PureTech Health plc (“PureTech Health”, “PureTech” or “the Company”), which is comprised of 
PureTech and its subsidiaries (together, the “Group”), is a clinical-stage biotherapeutics company 
dedicated to giving life to new classes of medicine to change the lives of patients with devastating 
diseases. We have created a broad and deep pipeline through our experienced research and 
development team and our extensive network of scientists, clinicians and industry leaders that is 
being advanced both internally and through our Founded Entities1 via our hub-and-spoke model. 

Our R&D engine has resulted in the development of 29 therapeutics and therapeutic candidates, 
including two that have received both US FDA clearance and European marketing authorization 
and a third (KarXT) that has been filed for FDA approval. A number of these programs are being 
advanced by PureTech as Internal Programs2 or by our Founded Entities in various indications 
and stages of clinical development, including registration enabling studies. All of the underlying 
programs and platforms that resulted in this pipeline of therapeutic candidates were initially 
identified or discovered and then advanced by the PureTech team through key validation points. 

The common theme across our programs is serious patient need. In many cases, these programs are 
identified based on previous signals of human efficacy or validated pharmacology, which has enabled 
us to advance therapeutic candidates with substantially de-risked profiles and robust development 
rationales. 80 percent of the trials that have been run by PureTech or our Founded Entities have been 
successful,3 and our probability of clinical success is six times better than the industry average.4

With this track record, we believe we are delivering on our promise to give life to science, advance 
novel medicines to patients and generate value for shareholders.

Every decision we make is anchored in our mission to 
advance treatments for patients that simultaneously 
create shareholder value, and I’m confident we will see 
continued success in both areas. 

Raju Kucherlapati, Ph.D.
Interim Chair of the Board of Directors

Since I joined the PureTech Board of 
Directors, I have witnessed the Company 
mature its hub-and-spoke business model 
with a commitment to deliver value to 
patients and shareholders. 

Consistent with our founding strategy, 
the Company has progressed promising 
programs in various therapeutic areas to 
inflection points and advanced them 
either internally or via Founded Entities. 
This uniquely efficient approach to R&D 
has enabled the development of a robust 
pipeline of new medicines, including two 
that have received FDA clearance and 
a third that has been filed for FDA 
approval, all without raising money from 
the capital markets in six years. This is 
a true testament to our model. 

PureTech’s exceptional productivity and 
capital discipline was exemplified in 2023. 
The Company embarked on a new phase 
of clinical expansion by creating two new 
Founded Entities from its internal work. 
The launches of Seaport Therapeutics and 
Gallop Oncology mark an exciting next 
chapter for PureTech, adding new 
de-risked specialist opportunities or 
“spokes” to the PureTech hub-and-spoke 
model. PureTech’s self-sustaining engine 
has enabled this continued operational 

progress despite adverse macroeconomic 
factors for the industry whilst also 
providing capital for the Company to 
return $50 million to shareholders via 
a share buyback program in addition to 
the recently proposed $100 million 
tender offer.

I would like to personally thank all of our 
shareholders for supporting us as we seek 
to improve patients’ lives. Every decision 
we make is anchored in our mission to 
advance treatments for patients that 
simultaneously create shareholder value, 
and I’m confident we will see continued 
success in both areas. 

On behalf of the Board, I would like to 
thank Daphne Zohar for her vision, 
leadership and dedication in founding and 
building PureTech. Daphne pioneered the 
hub-and-spoke model to create cutting-
edge medicines, assembled a leading 
team and positioned PureTech for an 
exciting future and continued growth, and 
I am confident that our Founded Entity, 
Seaport Therapeutics, will thrive with her 
at the helm as Chief Executive Officer. 
I would also like to welcome Bharatt 
Chowrira, Ph.D. J.D., into the Chief 
Executive Officer role at PureTech. 

A 30-year veteran of the biotech industry, 
Bharatt has held leadership roles including 
Chief Executive Officer, Chief Operating 
Officer and General Counsel in multiple 
biotech companies, including Auspex 
Pharmaceuticals Inc., which was acquired 
by Teva Pharmaceuticals for $3.5 billion, 
and Sirna Therapeutics, which was 
acquired by Merck & Co. for $1.1 billion. 
Bharatt has been a driving force behind 
PureTech’s achievements since 2017, 
serving as the Company’s President and 
Chief Business, Finance and Operating 
Officer and as a member of the board of 
directors, and I know our organization will 
continue to deliver value to patients and 
shareholders alike under his 
seasoned leadership.

Sincerely, 

Raju Kucherlapati, Ph.D.

Letter from the Chief Executive Officer

Shaping our 
future

2023 was a banner year for PureTech, and we are already charting an exciting 
path forward in 2024. I am proud and very humbled to assume the role of 
Chief Executive Officer at such a remarkable organization, and I look forward 
to continuing our transformational work for patients and shareholders. 

Bharatt Chowrira, Ph.D., J.D.
Chief Executive Officer and Member of the Board of Directors

PureTech made remarkable progress in 
2023 as we continued to deliver on our 
mission to give life to new classes of 
medicine that have the potential to 
change the lives of patients with 
devastating diseases. In 2023, we 
made significant strategic and clinical 
advancements across our hub-and-spoke 
R&D model, setting up the Company for 
growth in 2024 and beyond. 

Our strategy: A hub-and-spoke model 
that manages risk in advancing novel 
medicines for patients and generates 
value for shareholders 
At PureTech we pioneered the hub-and-
spoke model in biotech. Our “hub” is 
our core group of people, our proven, 
innovative R&D engine, and our 
capabilities at PureTech that are at the 
center of everything we do. It enables us 
to identify promising technologies and 
therapeutic opportunities; unlock their 
value through innovation; progress them 
through key de-risking milestones; and 
then develop them further – either 
internally or through the creation of 
a Founded Entity. The Founded Entities 
are our “spokes,” and they allow us to 
continue advancing candidates via 
a focused vehicle while sharing 

development costs with outside partners. 
These sector specialists not only enable 
cost efficiencies by investing capital in the 
Founded Entities, but also serve as 
external validation for the programs that 
we have until then developed in-house. 
This model ensures that promising new 
medicines are progressed to patients 
efficiently while we continue to generate 
and develop the next wave of novel 
candidates. It also yields a diversified 
portfolio, enabling us to have multiple 
shots on goal for creating shareholder 
value. Our distinctive approach is 
powered by three guiding principles: 
validated efficacy, clear patient benefit 
and an efficient de-risked path. 

This R&D model allows us to be more 
capital efficient, ensures that our interests 
are aligned with our shareholders and 
incentivizes us to move our resources to 
the programs with the greatest probability 
of success. It also brings in non-dilutive 
capital, which has resulted in PureTech not 
needing to raise money from the capital 
markets in over six years. In fact, nearly 
$3.8 billion has been raised by our 
Founded Entities since July 2018, of which 
96 percent was from third parties.1 In that 
time, we have generated tremendous

financings, loans and promissory 
notes, public offerings or grant 
awards. Funding figure excludes future 
milestone considerations received 
in conjunction with partnerships and 
collaborations.

value, including through the monetization 
of our stakes in Founded Entities, and have 
reinvested proceeds in further growing 
PureTech’s hub-and-spoke business. We 
have also returned $50 million to 
shareholders through our share buyback 
program and recently proposed an 
additional $100 million return to 
shareholders via a Tender Offer.2 The 
Board is committed to evaluating our 
capital allocation regularly (see page 8 
for further details), including assessing 
opportunities for capital returns to 
shareholders, subject to future 
monetization events and the Company’s 
operational needs.

We consistently maintain one of the most 
impressive track records in the biopharma 
industry, with a probability of clinical 
success that is six times higher than the 
industry average3. More than 80 percent4 
of our clinical trials have demonstrated 
success, and we take great pride in this 
track record. Across our programs, this has 
delivered a robust pipeline of new 
medicines that are poised for growth. This 
includes 29 new therapeutics and 
therapeutic candidates generated to date, 
with two taken from inception at PureTech 
to U.S. Food and Drug Administration 
(FDA) and EU regulatory clearances and 
one – Karuna’s KarXT (xanomeline-
trospium) – that has been filed for 
FDA approval.

Our model makes biopharma accessible 
both to generalist investors compelled by 
the meaningfulness of medical innovation 
and upside of cutting-edge R&D as well as 
to specialists comfortable with evaluating 
therapeutic opportunities. The former 
sees aligned incentives within PureTech’s 
internal activity and broader equity 
portfolio, through which they are shielded 
from the volatility of single asset binary 
outcomes so common in our industry. 

We have followed our model to success as 
our programs have matured and our 
internal capabilities have grown. 
Importantly, our R&D strategy is not only 
proven, but it is also scalable and 
repeatable. Consistent with our founding 
strategy, we have progressed several 
programs to inflection points, having 
sufficiently de-risked their core assets, and 
at the end of 2023, we added two new 
Founded Entity “spokes” to the PureTech 
“hub.” Our newly launched Seaport 
Therapeutics builds on the success of our 
Glyph platform and related therapeutic 
candidates to accelerate the development 
of new neuropsychiatric medicines in 
areas of high unmet need. I am also 
delighted that PureTech has indicated the 
launch  Gallop Oncology™, which builds 
on the promising clinical and preclinical 
data generated from our LYT-200 program 
in hematological malignancies and solid 
tumors. In creating these focused entities, 

we continue to deliver on our fundamental 
goal: advance novel therapeutic solutions 
to patients battling serious, 
devastating conditions.

Internal Programs: Effective 
identification and de-risking of the most 
promising technologies
Most of the candidates that we advance 
internally are centered around a strategy 
that focuses on established biological 
principles to promptly progress 
therapeutics with validated efficacy and 
clinical signals.

This strategy is exemplified through our 
lead Internal Program, LYT-100, 
a deuterated form of pirfenidone. 
Pirfenidone (Esbriet®) is approved for the 
treatment of idiopathic pulmonary fibrosis 
(IPF) in the US and other countries, having 
been shown to slow the decline of lung 
function and extend life by an average of 
2.5 years.7 It is one of two standard of care 
treatments for IPF, with nintedanib 
(OFEV®) being the other, yet – despite the 
proven efficacy – only about 25 percent of 
IPF patients with this rare, progressive and 
fatal disease are currently being treated 
with either standard of care drug, largely 
due to tolerability issues. 

LYT-100 is designed to retain the beneficial 
pharmacology and clinically-validated 
efficacy of pirfenidone with a highly 

Case study

The KarXT 
journey at 
PureTech

p14

Karuna’s KarXT, invented and advanced by 
PureTech, is a hallmark for how we create 
value. Patients living with schizophrenia 
need new treatment options as current 
standard-of-care antipsychotics have 
significant side effects and poor 
adherence rates. Xanomeline, originally 
discovered by Eli Lilly, demonstrated 
clinical efficacy but was shelved due to its 
side effect profile. PureTech’s team 
invented and filed patents for a synergistic 
agonist and antagonist concept (e.g., 
xanomeline + trospium chloride) that 
would unlock the efficacy of xanomeline 
and allow for improved tolerability. 
Following an exceptionally successful 
clinical journey, FDA approval for KarXT is 
anticipated in 2024. If approved, KarXT will 
deliver the first new mechanism for 
treating schizophrenia in over 50 years, 
and - as a result of KarXT’s remarkable 
innovation story – Bristol Myers Squibb 
(BMS) acquired Karuna for $14 billion in the 
March 2024 post-period.

In addition to transforming the treatment 
landscape for patients with schizophrenia, 
Karuna’s success has allowed us to 
generate approximately $1.1 billion in cash 
to date5 to fund our operations and fuel 
our next wave of innovation. This has been 
realized through the monetization of 
a portion of our holdings in Karuna, gross 
proceeds from BMS’ acquisition valued at 
$293 million as well as a strategic royalty 
agreement for KarXT with Royalty Pharma. 
The $500 million transaction with Royalty 
Pharma, which was announced in March 
2023, included $100 million in cash 
received up front in 2023 and up to 
$400 million in additional payments 
contingent on the achievement of certain 
regulatory and commercial milestones. As 
part of this transaction, we sold PureTech’s 
rights to receive a 3 percent royalty from 
Karuna to Royalty Pharma on sales up to 
$2 billion annually, after which Royalty will 
receive 33 percent and PureTech will retain 
67 percent of the royalty payments.6

differentiated pharmacokinetic profile that has 
translated into favorable tolerability in multiple 
clinical studies. In fact, we have demonstrated 
an approximately 50 percent reduction in 
participants experiencing gastro-intestinal (GI) 
and central nervous system (CNS)-related 
adverse events (AEs) in a crossover study of 
LYT-100 vs. pirfenidone. We believe this profile 
has the potential to keep patients on treatment 
longer, enabling more optimal disease 
management and patient outcomes. 

Beyond this promising profile, we have also 
shown that LYT-100 is well-tolerated at exposure 
levels higher than the FDA-approved dose of 
pirfenidone, which may enable enhanced 
efficacy given Phase 3 data with pirfenidone that 
showed a dose-response effect on forced vital 
capacity and survival in people with IPF.8

Our goal with the ongoing Phase 2b ELEVATE 
IPF trial is to validate the ability of LYT-100 to 
deliver a more tolerable treatment with 
comparable efficacy to pirfenidone at one dose 
while also exploring the potential for enhanced 
efficacy at a higher dose. The trial is fully 
enrolled, and we look forward to sharing topline 
results in the fourth quarter of 2024.

Founded Entities: Launch of two new 
Founded Entities; KarXT seeking FDA 
approval; clinical and commercial progress 
across the Group 
We are constantly evaluating our Internal 
Programs for candidates that can follow the 

This agreement supplied us with non-dilutive 
capital in the short-term and has great 
potential for long-term earnings based on 
KarXT’s future regulatory and commercial 
milestones, as well as product sales.

We believe KarXT’s journey to regulators 
benefited from our creation of Karuna as 
a Founded Entity focused on a specialized 
asset. Initially, KarXT was part of a diversified 
portfolio undergoing de-risking within 
PureTech. Eventually its potential and the 
forecasted demands of its later-stage clinical 
journey informed our decision to house 
Karuna as a stand-alone Founded Entity that 
could draw the right mix of investors, including 
specialists, and dedicated personnel and 
expertise to effectively and efficiently drive its 
progress. The KarXT story therefore 
showcases both sides of our value proposition: 
de-risked portfolio development in-house 
and specialized asset advancement via 
Founded Entities.

KarXT “playbook”, and in 2023 we made the 
decision to advance several into new 
Founded Entities. 

Seaport Therapeutics was born from our Glyph 
technology platform, which has demonstrated 
clinical proof-of-concept and has been prolific in 
producing new therapeutic candidates. The 
proprietary Glyph platform is designed to 
enable and enhance oral bioavailability, bypass 
first-pass metabolism and reduce 
hepatotoxicity and other side effects to advance 
active drugs that were previously held back by 
those limitations. With this technology and 
candidate portfolio, including SPT-300 (Glyph 
allopregnanolone; formerly LYT-300), SPT-320 
(Glyph agomelatine; formerly LYT-320), and SPT 
348 (a prodrug of a non-hallucinogenic 
neuroplastogen) Seaport’s mission, similar to 
Karuna’s, is to advance first-and-best-in class 
therapeutics for patients with anxiety, 
depression and other neuropsychiatric 
disorders. The Seaport programs made 
important advancements at PureTech in 2023, 
with topline Phase 2a data announced from 
a proof-of-concept study of SPT-300, a grant 
received from the U.S. Department of Defense 
of up to $11.4 million to advance SPT-300 in 
Fragile X-associated Ataxia Syndrome, and the 
nomination of SPT-320. In the 2024 post-period, 
we announced the launch of Seaport with 
a $100 million9 oversubscribed Series A 
financing with participation from top tier biotech 
investors ARCH Venture Partners, Sofinnova 
Investments and Third Rock Ventures. Seaport 
will be led by PureTech Founding CEO Daphne 
Zohar. Following the Series A financing, 
PureTech holds equity ownership in Seaport of 
61.5 percent. 

We also indicated the intent to launch Gallop 
Oncology from our LYT-200 (anti-galectin-9) 
program. We are advancing a differentiated 
approach to cancer treatment by targeting the 
pro-tumor mechanisms of galectin-9 for the 
treatment of hematological malignancies and 
solid tumors. A large body of preclinical and 
human data underscores the importance of 
galectin-9 as a potent oncogenic driver in 
leukemia cells and an immunosuppressive 
protein, and LYT-200 has demonstrated direct 
cytotoxic, anti-leukemic effects through 
multiple mechanisms as well as anti-tumor 
efficacy. We’re excited by the data generated to 
date in acute myeloid leukemia (AML) and 
high-risk myelodysplastic syndrome (MDS), as 
well as head and neck cancers. We expect 
additional data from the ongoing Phase 1b 
clinical trial for the potential treatment of AML 
and MDS to be presented in a scientific forum in 
2024, as well as additional data from the

10  EndeavorRx is a digital therapeutic 
indicated to improve attention 
function as measured by computer-
based testing in children ages 8-17 
years old with primarily inattentive 
or combined-type ADHD, who have 
a demonstrated attention issue. 
Patients who engage with EndeavorRx 
demonstrate improvements in 
a digitally assessed measure Test 
of Variables of Attention (TOVA®) of 
sustained and selective attention 
and may not display benefits in 
typical behavioral symptoms, such 
as hyperactivity. EndeavorRx should 
be considered for use as part of 
a therapeutic program that may 
include clinician-directed therapy, 
medication, and/or educational 
programs, which further address 
symptoms of the disorder. EndeavorRx 
is available by prescription only. 
It is not intended to be used as 
a stand-alone therapeutic and is not 
a substitution for a child’s medication. 
The most common side effect 
observed in children in EndeavorRx’s 
clinical trials was a feeling of 
frustration, as the game can be quite 
challenging at times. No serious 
adverse events were associated with 
its use. EndeavorRx is recommended 
to be used for approximately 25 
minutes a day, 5 days a week, over 
initially at least 4 consecutive weeks, 
or as recommended by your child’s 
health care provider. To learn more 
about EndeavorRx, please visit 
EndeavorRx.com.

11  EndeavorOTC is a digital therapeutic 

indicated to improve attention 
function, ADHD symptoms and quality 
of life in adults 18 years of age and 
older with primarily inattentive or 
combined-type ADHD. EndeavorOTC 
utilizes the same proprietary 
technology underlying EndeavorRx, 
a prescription digital therapeutic 
indicated to improve attention 
function in children ages 8-17. 
EndeavorOTC is available under the 
U.S. Food and Drug Administration’s 
current Enforcement Policy for Digital 
Health Devices for Treating Psychiatric 
Disorders During the Coronavirus 
Disease 2019 (COVID-19) Public Health 
Emergency. EndeavorOTC has not 
been cleared or authorized by the U.S. 
Food and Drug Administration for its 
indications. It is recommended that 
patients speak to their health care 
provider before starting EndeavorOTC 
treatment. No serious adverse events 
have been reported in any of our 
clinical studies. To learn more, visit

Phase 1b trial in combination with tislelizumab 
for the potential treatment of advanced 
solid tumors.

Several of our other Founded Entities have 
made key progress in 2023 as well. As noted, 
Karuna submitted a New Drug Application to 
the FDA for KarXT for the treatment of 
schizophrenia in adult patients, which was 
accepted and granted a Prescription Drug User 
Fee Act (PDUFA) date of September 26, 2024. 
The company was subsequently acquired by 
BMS for $14 billion. The clinical program 
expanding the evidence base for KarXT 
continued with additional positive data 
reported and two Phase 3 trial initiations in 
Alzheimer’s disease.

At Vedanta, the team administered the initial 
dose to the first patient for the company’s 
Phase 2 COLLECTiVE202 clinical trial of VE202 
for the management of ulcerative colitis and the 
program was granted Fast Track designation by 
the FDA. Vedanta also plans to initiate a Phase 3 
clinical trial of VE303 in patients at high risk for 
recurrent Clostridioides difficile infection in the 
second quarter of 2024. Vor also made progress 
in the clinic and announced new clinical data 
from its Phase 1/2a first-in-human study of 
trem-cel (VOR33) in patients with AML, 
titled VBP101. 

Notably, Akili received U.S. FDA authorization to 
broaden the label for EndeavorRx®.10 This 
expansion now includes children aged 13 to 
17 years old with attention-deficit/hyperactivity 
disorder (ADHD), which will increase the 
eligibility for this treatment and thus double 
the number of pediatric patients with ADHD 
who can benefit. Akili also announced plans to 
transition from a prescription to a non-
prescription business model to further increase 
access. Further to this strategic plan, Akili 
launched EndeavorOTC®11 for adults with 
ADHD, following positive results from a clinical 
trial evaluating EndeavorRx in this population. 

Finally, Sonde Health increased its sales and 
growth through establishing partnerships with 
a variety of providers, health companies, 
pharmaceutical entities and manufacturers. 
Entrega also continued its R&D work to advance 
its core platform for the oral administration of 
biologics, vaccines and other drugs that are 
usually not effectively absorbed when 
administered orally. 

Our future: Crystalizing value
We have successfully grown a pipeline of 
therapeutics and candidates, carefully allocated 

our resources and diligently executed on our 
mission. We retain substantial holdings in both 
our public and private Founded Entities; are due 
certain royalties and milestone payments as 
some of these programs advance; maintain 
a strong balance sheet to support our existing 
programs, and Founded Entities, and fuel our 
future innovation; and we will have returned 
$150 million to shareholders through our 
recently completed share buyback program and 
proposed Tender Offer. These achievements 
underscore the significant value we have 
created that has not been fully recognized by 
the market. I am committed to evaluating ways 
to unlock and crystalize that value for 
shareholders and look forward to sharing my 
vision for the Company’s future growth in the 
coming months.

Thanks to our network of supporters for 
giving life to science 
After an extremely productive year, I would like 
to extend my thanks and appreciation to our 
dedicated teams – both at PureTech and across 
our Founded Entities – who play an essential 
role in driving highly innovative and impactful 
R&D forward. Your commitment to our cause 
is inspiring, and I am so grateful to work 
alongside you in the name of serving patients 
and our shareholders. 

I would also like to thank our talented board for 
their guidance, in addition to our wide network 
of shareholders, collaborators, and advisors for 
their continued support of our vision. 

I also want to express my sincere gratitude to 
Daphne Zohar for her remarkable leadership 
since the inception of PureTech and for guiding 
the Company into this exciting new phase. I am 
pleased that we will continue to benefit from her 
entrepreneurial spirit as she drives further value 
for PureTech in her new role as CEO of Seaport.

2023 was a banner year for PureTech, and we are 
already charting an exciting path forward in 
2024. I am proud and very humbled to assume 
the role of CEO at such a remarkable 
organization, and I look forward to continuing 
our transformational work for patients and 
shareholders.

PureTech determines its capital allocation with a measured approach that balances support for its current Internal and Founded 
Entity Programs and the funding of future innovation, with the goal of maximizing shareholder returns. Key components include:

Capital Returns

Strategy

Value impact

Taxes

In 2024, PureTech has proposed a $100 million Tender Offer1. The board will continue to assess ongoing 
opportunities to improve shareholder returns, including additional capital returns to shareholders from future 
monetization events, while maintaining a cash runway of at least three years to support our Internal Programs, 
Founded Entities, future innovation and operational needs.

We believe that periodic capital returns to shareholders are an important acknowledgement of the value created 
for shareholders that may not be reflected in the share price. We believe the proposed Tender Offer1 is a capital 
efficient mechanism that maximizes shareholder returns, provides liquidity and reduces the outstanding share 
count while allowing us to maintain a strong balance sheet.

As a U.S. domiciled taxpayer, the amount of tax that we would owe on any proceeds we may generate between federal and state 
obligations is in the mid to high 20 percent range; however, the exact amount is dependent upon a number of factors including our 
ability to claim net operating losses or other losses (e.g., operating losses, capital losses) and utilize R&D credits. We actively work to 
appropriately manage our tax burden and requirements. We currently anticipate having fairly minimal losses in 2024 as compared to 
our sizeable gains in the year, especially with respect to Karuna in light of its sale to Bristol Myers Squibb. Further guidance around our 
anticipated 2024 tax position will be set forth in our 2024 Half Year report.

Founded Entities

Strategy

Balancing costs, benefits, risks and rewards, we may move assets from Internal Programs to Founded Entities. 
We may continue to make investments into our Founded Entities, such as Seaport, in which we invested 
$32 million in conjunction with the Series A financing. The decision to contribute capital to a Founded Entity 
financing is intended to maintain PureTech’s ownership position or minimize dilution of PureTech’s position in 
a Founded Entity or, in certain circumstances, to help catalyze a financing round that we believe will bring 
additional long-term value to the company. PureTech may participate in financing rounds for existing Founded 
Entities as well as newly formed Founded Entities.

Value impact

Our Founded Entities are a prospective source of non-dilutive capital that enable us to advance potential 
medicines to patients efficiently, reduce our financial exposure, return capital to shareholders and largely 
self-fund our operations through future monetization events. Housing our candidates and/or platforms in this 
structure attracts specialized management teams and defrays cost-intensive late-stage development work while 
maintaining financial upside potential upon success.

Existing programs

Strategy

Value impact

New innovation

Strategy

Our most advanced internal program is LYT-100, for which we expect Phase 2b data in the fourth quarter of 2024. 
PureTech anticipates completing the ongoing trial with existing capital. The necessary level of spend for 
a subsequent Phase 3 trial for LYT-100 will be driven by the required number of patients and exact design, both of 
which will be informed by the results of the Phase 2b trial and discussions with the FDA. If the data are positive, 
PureTech anticipates having optionality to pursue third-party funding to support a subsequent trial. Additionally, 
we intend to develop LYT-200 in our recently created Founded Entity Gallop Oncology. PureTech anticipates 
funding the continued development of LYT-200 until Gallop Oncology is positioned to raise capital from third 
party investors at an appropriate juncture. As we have historically demonstrated, if our candidates don’t achieve 
our pre-specified threshold for advancement early on, we move our resources to areas that we believe are better 
positioned to add value.

Our development strategy is intended to align our interests with those of our shareholders by pursuing internal 
de-risking activities to ensure that our assets under development present a demonstrable value proposition. 
We avoid the bias to continue by establishing a high threshold for further development. Once a program has 
reached the next key value generating inflection point, we retain the optionality to continue internal 
development for further value accretion, or we may pursue external funding, collaborations or partnerships 
to reduce risk and expense while maximizing shareholder value.

Consistent with our founding hub-and-spoke R&D model, we are continuously sourcing innovations which – with 
further work – could create significant value. Subject to consultation with our esteemed R&D committee and 
ultimately our Board, both of which assist us in our rigorous process of vetting potential assets, we anticipate 
selecting up to two assets or programs per year that require minimal spend to get to a value inflection point and 
will do so in a capital efficient manner. New innovations may yield assets  that could be complementary to our 
existing programs.

Value impact

Our innovation engine enables the growth of our portfolio to ensure the next wave of candidates is progressing 
towards value creating milestones for shareholders. We will continue to examine the overall value created from 
these initiatives to ensure they are driving shareholder value and consider other mechanisms as appropriate.

Chapter 7 Trustee provided notice that a third party bid to purchase the assets subject to the bankruptcy had been accepted as a stalking horse bid, subject to Bankruptcy Court 
approval. If such sale of the assets is ultimately approved by the Bankruptcy Court and consummated, it is expected that PureTech could recover a portion of its investment in Gelesis 
senior secured convertible promissory notes. The ultimate resolution of this matter, any potential recovery, and the associated timing remains uncertain.

LYT-100 (deupirfenidone) is currently being developed internally at PureTech for the 
treatment of idiopathic pulmonary fibrosis (IPF), which is a rare, progressive and fatal 
disease. It has the potential to address multiple underserved diseases, including progressive 
fibrosing interstitial lung diseases, a group of lung diseases closely related to IPF, as well as 
other fibrotic conditions where there is human data with pirfenidone that is suggestive of 
clinical benefit.

 — We acquired LYT-100 based on insights gained internally and via unpublished findings through 
our network of collaborators. LYT-100, which is a deuterated form of pirfenidone, was originally 
developed by Auspex Pharmaceuticals, Inc. (Auspex), where our Chief Executive Officer, Bharatt 
Chowrira, Ph.D., J.D., served as Chief Operating Officer. Auspex (now a wholly-owned subsidiary 
of Teva Pharmaceuticals), pioneered the deuteration technology and successfully developed 
deutetrabenazine (Austedo®), the first FDA-approved deuterated drug. 

 — Pirfenidone (Esbriet®) is approved for the treatment of IPF in the U.S. and other countries. It has 

been shown to slow the decline of lung function and research suggests it extends life by 
approximately 2.5 years in patients with IPF.1 It is one of two standard of care treatments for IPF, 
along with nintedanib (OFEV®). Only about 25% of IPF patients are currently being treated with 
either standard of care drug,2 yet combined sales of Esbriet and Ofev in 2022 were more than 
$4 billion, representing a significant market opportunity in IPF and other fibrotic lung diseases.3 
LYT-100 is designed to retain the beneficial pharmacology and clinically-validated efficacy of 
pirfenidone with a highly differentiated pharmacokinetic profile that has translated into 
favorable tolerability in multiple clinical studies and has the potential to keep patients on 
treatment longer to enable more optimal disease management.

IPF
 — LYT-100 is currently being evaluated in ELEVATE IPF, a global, randomized, double-blind, 

placebo-controlled Phase 2b clinical trial designed to evaluate the efficacy, tolerability, safety 
and dosing regimen of LYT-100 in patients with IPF compared to placebo. The trial has four arms: 
placebo, pirfenidone, a dose of LYT-100 with comparable exposure to the FDA-approved dose of 
pirfenidone and a dose of LYT-100 with a higher level of exposure than the FDA-approved dose of 
pirfenidone. The primary endpoint is the rate of decline in Forced Vital Capacity (FVC) for the 
combined LYT-100 arms versus placebo over the 26-week treatment period using a prespecified 
Bayesian approach. Other key endpoints include tolerability measures, biomarkers and patient-
reported outcomes. Both doses of LYT-100 will be compared to pirfenidone, though the trial is 
not powered to show a statistical difference in efficacy between LYT-100 and pirfenidone. 

 — LYT-100 has shown a 50% reduction in gastro-intestinal related adverse events in a crossover trial 
versus pirfenidone in healthy older adults. We believe the differentiated tolerability profile of 
LYT-100 will address one of the key reasons that patients on current standard of care dose reduce, 
discontinue or switch from otherwise efficacious treatments.2,4 We have also been able to dose 
LYT-100 at a higher exposure level, potentially enabling improved efficacy. Given this, we believe 
LYT-100 has the potential to become standard of care and to become a backbone therapy in the 
treatment for IPF.

 — In the April 2024 post-period, enrollment was completed in the ELEVATE IPF Phase 2b clinical trial 

evaluating LYT-100 in patients with IPF. 

 — In October 2023, expanded data were presented at the CHEST Annual Meeting from 

a completed trial of LYT-100 in healthy older adults, which informed the two doses selected for 
the ongoing Phase 2b trial. In addition to supporting the improved tolerability of LYT-100 versus 
the FDA-approved dose of pirfenidone, the data supported the selection of a higher dose of 
LYT-100 with the potential for improved efficacy that is now being evaluated in ELEVATE IPF.

Expected milestones

 — Topline results from ELEVATE IPF are expected in Q4 2024. A streamlined development program 

is planned using the same endpoints that have supported past approvals. Pending positive 
clinical and regulatory feedback, the program will advance into a Phase 3 trial. We believe the 
results of the Phase 2b trial, together with a Phase 3 trial, could serve as the basis for registration 
in the U.S. and other geographies.

 — As of December 31, 2023, the LYT-100 patent portfolio includes 32 active patents acquired from 
Auspex, which provide broad coverage of compositions of matter, formulations and methods of 
use for deuterated pirfenidone, including the LYT-100 deupirfenidone compound. This IP estate 
comprises six issued U.S. patents and 26 patents issued in 23 foreign jurisdictions, which are 
expected to expire in 2028 and may be extended by up to five years. In addition, we have 
in-licensed one U.S. patent and one U.S. patent application from Auspex directed to formulations 
of deuterated pirfenidone, both of which expire in 2035, and also filed additional patent 
applications on deupirfenidone, including nine (9) pending U.S. patent applications, 17 foreign 
applications and three (3) international PCT applications directed to the use of deuterated 
pirfenidone, including LYT-100, for the treatment of a range of conditions. Any issued patents 
claiming priority to these applications are expected to expire in 2039 through 2044, exclusive of 
possible patent term adjustments or extensions.

Program discovery

PureTech team

Key milestones  
achieved and  
development status

Seaport Therapeutics is a clinical-stage biopharmaceutical company charting a proven path in 
neuropsychiatry. Seaport is advancing a clinical-stage pipeline of neuropsychiatric medicines 
that includes its most advanced therapeutic candidate, SPT-300 (formerly known as LYT-300), 
an oral prodrug of allopregnanolone, which is being advanced for the treatment of anxious 
depression, SPT-320 (formerly known as LYT-320), a novel prodrug of agomelatine, which 
is being advanced for the treatment of Generalized Anxiety Disorder (GAD), and SPT-348, 
a prodrug of a non-hallucinogenic neuroplastogen, which is in development for the treatment 
of mood and other neuropsychiatric disorders. Beyond these programs, Seaport has multiple 
discovery and preclinical programs underway. All of the programs in Seaport’s pipeline are 
based on the Glyph™ platform, which is designed to enable and enhance oral bioavailability, 
avoid first-pass metabolism and reduce hepatotoxicity and other side effects to advance 
active drugs that were previously held back by those limitations. The design and optimization 
of drug-specific chemistry and pharmacology is tailored for each program. This robust and 
consistent application of Glyph technology has led to the rapid growth of a robust pipeline 
of neuropsychiatric medicines.

 — With intersecting interests in enabling promising neuropsychiatric drugs to reach their full 

potential and the emerging science around the lymphatic system, we identified a breakthrough 
technology being developed at Monash University that had the potential to selectively transport 
therapeutic molecules through the lymphatic system. 

 — With the Glyph platform, drugs are absorbed like dietary fats through the intestinal lymphatic 
system and transported into circulation. The Glyph technology has the potential to be widely 
applied to many therapeutic molecules that have high first-pass metabolism leading to low 
bioavailability and/or side effects, including hepatotoxicity. We prioritized areas of high unmet 
patient need where the broad application of treatment options with validated efficacy was 
untapped due to these issues. The Glyph platform has been refined at PureTech and Seaport to 
efficiently generate multiple therapeutic candidates within Seaport’s pipeline.

 — In December 2023, SPT-320 (Glyph-agomelatine) was nominated as a new therapeutic candidate 
powered by the Glyph platform. A novel prodrug of agomelatine, SPT-320 is in development for 
the treatment of GAD. Agomelatine is effective in treating GAD and major depressive disorder 
(MDD) and offers superior tolerability to standard of care. However, agomelatine has low (~1%) 
bioavailability due to high first-pass metabolism, resulting in increased liver enzymes in some 
patients and necessitating frequent liver function monitoring that has held back the drug. 
SPT-320 uses the Glyph platform to bypass first-pass metabolism by the liver and thus has the 
potential to reduce liver exposure, hepatotoxicity, and the need for liver function monitoring. 
 — In November 2023, successful topline results from the randomized, proof-of-concept Phase 2a 

trial of SPT-300 (Glyph-allopregnanolone) were reported. The trial was designed to evaluate the 
salivary cortisol response in the Trier Social Stress Test, a validated clinical model of anxiety in 
healthy volunteers. Oral administration of SPT-300 achieved the trial’s primary endpoint of 
a statistically significant reduction versus placebo in the increase from baseline to peak levels of 
the stress hormone salivary cortisol (p=0.0001) with a treatment effect size versus placebo of 
0.72, measured by Cohen’s d. 

 — In August 2023, it was announced that the U.S. Department of Defense awarded up to 

$11.4 million to advance SPT-300 for the treatment of Fragile X-associated Tremor/Ataxia 
Syndrome (FXTAS). 

Expected milestones

 — Following the completion of an oversubscribed $100 million Series A financing, Seaport is 
evaluating its timelines and will provide public guidance around milestones in due course.

Intellectual property

 — As of December 31, 2023, the extensive Glyph intellectual property portfolio includes 20 families 
of patent filings directed to platform technologies which provide expansive coverage for a broad 
range of novel linker chemistries, as well as product technologies directed to compositions of 
matter for a wide variety of prodrugs and methods of use for the treatment of various indications, 
including several CNS-related indications. This intellectual property estate comprises eight (8) 
families of patent filings that provide exclusive rights to IP that is co-owned or exclusively licensed 
with Monash University and twelve (12) families of company-owned patent applications covering 
various aspects of the Glyph prodrug technologies, including compositions of matter, 
formulations, synthetic processes, and methods of therapeutic uses. Any patents to issue from 
these patent families are expected to expire in 2035 through 2044, exclusive of possible patent 
term adjustments or extensions or other forms of exclusivity. PureTech retains the right to 
develop non-CNS therapies utilizing the Glyph platform, subject to certain contractual 
constraints.

Karuna Therapeutics is a wholly owned subsidiary of Bristol Myers Squibb (BMS) driven 
to create and deliver transformative medicines for people living with psychiatric and 
neurological conditions. Karuna’s lead candidate KarXT (xanomeline-trospium) is under 
review by the U.S. Food and Drug Administration (FDA) for the treatment of schizophrenia 
in adults. KarXT is also being evaluated in Phase 3 clinical trials as a potential adjunctive 
treatment for schizophrenia and as a potential treatment for psychosis in Alzheimer’s disease.

 — We and our collaborators, including leading schizophrenia experts, were excited about efficacy 
data generated in schizophrenia and Alzheimer’s disease by Eli Lilly with xanomeline, which had 
notable efficacy stemming from its activation of muscarinic receptors (M1 and M4) but had been 
held back by gastrointestinal tolerability issues. To overcome this, we invented KarXT, an oral M1/
M4-preferring muscarinic agonist, by combining xanomeline (a muscarinic agonist) with 
trospium (a peripherally acting muscarinic antagonist that doesn’t cross the blood brain barrier). 
This enabled the beneficial effects of M1/M4 activation in the brain without the peripheral side 
effects. We conducted key human tolerability proof-of-concept studies with KarXT that allowed 
Karuna to advance it further in schizophrenia patients. Karuna licensed the key KarXT intellectual 
property from PureTech. KarXT has been submitted to the FDA, and – if approved – we will have 
pioneered the development of the first new class of medicine for schizophrenia in over 50 years.

 — In December 2023, Karuna announced they entered into a definitive agreement with BMS under 
which BMS has agreed to acquire Karuna for $330.00 per share in cash, for a total equity value 
of $14.0 billion. In the March 2024 post-period, the transaction was completed and Karuna is now 
a wholly owned subsidiary of BMS.

 — In November 2023, Karuna announced that the FDA accepted its new drug application for KarXT 
(xanomeline-trospium) for the treatment of schizophrenia and has granted a Prescription Drug 
User Fee Act (PDUFA) date of September 26, 2024. 

 — In November 2023, Karuna announced positive results from the Phase 1b trial evaluating the 

effect of KarXT on 24-hour ambulatory systolic blood pressure in adults with schizophrenia. The 
primary endpoint in the trial was the change from baseline at week 8 in 24-hour average 
ambulatory systolic blood pressure. In the trial, KarXT demonstrated a mean change from 
baseline to week 8 in 24-hour ambulatory systolic blood pressure of -0.59 mmHg. The upper 
bound of the two-sided 95% confidence interval for the mean change from baseline to week 8 
was 1.60 mmHg, thus ruling out a clinically meaningful increase in blood pressure (defined per 
FDA guidance as ≥3 mmHg change from baseline). Daytime and nighttime systolic blood 
pressure measurements showed no meaningful change and were generally consistent with the 
24-hour average. Additional vital sign measures collected in the trial, including 24-hour average 
diastolic blood pressure and heart rate, were consistent with prior trials of KarXT in schizophrenia. 
Further, KarXT was generally well tolerated, with a side effect profile consistent with prior trials in 
the EMERGENT program.

 — In March 2023, Karuna announced positive topline results from the Phase 3 EMERGENT-3 trial 

evaluating the efficacy, safety, and tolerability of KarXT in adults with schizophrenia. The trial met 
its primary endpoint, with KarXT demonstrating a statistically significant and clinically 
meaningful 8.4-point reduction in Positive and Negative Syndrome Scale (PANSS) total score 
compared to placebo (-20.6 KarXT vs. -12.2 placebo; p<0.0001) at Week 5 (Cohen’s d effect size of 
0.60). Consistent with prior trials, KarXT demonstrated an early and sustained statistically 
significant reduction of symptoms from Week 2 (p<0.05) through the end of the trial as assessed 
by PANSS total score. KarXT also demonstrated reductions in positive and negative symptoms of 
schizophrenia as measured by PANSS positive and PANSS negative Marder factor subscales. 
KarXT was generally well tolerated, with a side effect profile substantially consistent with 
previous trials of KarXT in schizophrenia.

 — In the third quarter of 2023, Karuna initiated the Phase 3 ADEPT-2 and ADEPT-3 trials for 

psychosis in Alzheimer’s disease (AD). 

Expected milestones

 — Karuna’s New Drug Application for KarXT in schizophrenia has been granted a PDUFA date of 

September 26, 2024. If approved, KarXT is expected to launch in late 2024.

1  As of 22 March 2023, PureTech has sold its right to receive a 3 percent royalty from Karuna to Royalty Pharma on net sales up to 

$2 billion annually, after which threshold PureTech will receive 67 percent of the royalty payments and Royalty Pharma will receive 
33 percent.

Key milestones  
achieved and  
development status

Gallop Oncology™ is advancing a first-in-class, mechanistically differentiated approach to 
cancer treatment by targeting a novel, pro-tumor and immunosuppressive molecule. Gallop’s 
LYT-200 is ananti-galectin-9 monoclonal antibody (mAb) being developed for the treatment 
of acute myeloid leukemia (AML) and high-risk myelodysplastic syndromes (MDS) and head 
and neck cancers. 

 — With a focus on providing significant therapeutic benefit to cancer patients, we opportunistically 
identified a foundational immunosuppressive/pro-tumor mechanism(s) involving galectin-9, 
which was the basis of certain intellectual property that we licensed from New York University 
prior to its publication in Nature Medicine. Galectin-9 promotes multiple immunosuppressive 
pathways in the context of solid tumors and blocking galectin-9 results in tumor cell death in the 
context of AML and other hematological malignancies. High levels of galectin-9 expression in 
tumor tissue, on leukemia cells as well as in patients’ blood are linked to more advanced disease 
and worse outcomes. LYT-200 is a fully human IgG4 monoclonal antibody designed to inhibit the 
activity of galectin-9. We believe that LYT-200 is the most advanced clinical program against this 
target. It has the potential to be used as a single agent and in combination with other anti-cancer 
therapies, depending on the cancer type, treatment setting and line of treatment. LYT-200 has 
also demonstrated direct cytotoxic, anti-leukemic effects through multiple mechanisms, as well 
as synergy with standard of care in preclinical models. 

 — Preclinical work demonstrates single agent mechanistic and anti-tumor efficacy of LYT- 200 in 

multiple animal and patient-derived tumor cell models.

AML
 — In the February 2024 post-period, the U.S. Food and Drug Administration (FDA) granted Orphan 
Drug Designation to LYT-200 for the treatment of AML. The FDA grants orphan drug designation 
to novel products for the treatment of conditions affecting fewer than 200,000 persons in the U.S, 
and it qualifies the company for incentives including tax credits for some clinical trials and 
eligibility for seven years of market exclusivity in the U.S., if the drug is approved for AML.

 — In December 2023, it was announced that three dose escalation cohorts had been completed at 
weekly doses of 2 mg/kg (cohort 1), 4 mg/kg (cohort 2) and 7.5 mg/kg (cohort 3) in the ongoing 
Phase 1b trial evaluating LYT-200 as a single agent in relapsed/refractory AML and MDS patients. 
In a heavily pre-treated patient population, the early data demonstrate a favorable safety and 
tolerability profile of LYT-200 with no dose limiting toxicities. In the first cohort, disease 
stabilization was observed in two of the five patients treated, with one patient achieving red 
blood cell transfusion independence. In the second cohort, disease stabilization was observed in 
two of the four patients treated. In the third cohort, disease stabilization was observed in all four 
of the patients treated, with a reduction in bone marrow blasts observed in two of the four 
patients and the clearance of peripheral blasts observed in one patient. Two patients achieved 
more than 50 percent bone marrow blast reduction, with one of these patients observing an 
increase in platelet count without transfusions. The fourth cohort, evaluating a weekly regimen of 
LYT-200 at the 12 mg/kg dose, is still ongoing, and additional data are expected to be shared in 
a scientific forum.

Locally advanced/metastatic solid tumors
 — In the March 2024 post-period, the FDA granted Fast Track designation for LYT-200 in 

combination with anti-PD1 therapy for the treatment of recurrent/metastatic head and neck 
cancers. Fast Track designation is a process designed to streamline the development and 
accelerate the assessment of drugs that target serious conditions with unmet need.

 — In December 2023, initial data from the Phase 1 portion of the Phase 1/2 dose escalation and 

expansion clinical trial of LYT-200 was announced. The initial data were presented at European 
Society for Medical Oncology meeting and demonstrate a favorable safety profile in all cohorts, 
including the monotherapy and combination arms with tislelizumab, an anti-PD-1 antibody being 
developed by BeiGene, and show disease control and suggestion of anti-tumor activity in 
combination with tislelizumab. In the combination cohort, anti-tumor activity was observed in 
patients with relapsed or refractory head and neck cancer, a patient population that has 
historically demonstrated a low response rate to anti-PD-1 agents of around 20 percent and 
10 percent with chemotherapy1.

 — LYT-200 has broad intellectual property coverage for these antibody-based immunotherapy 

technologies. As of December 31, 2023, there are 15 families of intellectual property within this 
patent portfolio, including eight families of patent filings that are co-owned with and/or 
exclusively licensed from New York University which cover antibodies that target galectin-9, 
including LYT-200, and methods of using these antibodies in various immuno-oncology 
technologies and treatment methods. In addition, the intellectual property portfolio includes six 
families of company-owned patent applications covering the use of anti-galectin-9 antibodies in 
the diagnosis and treatment of various cancers, including solid tumors and hematological 
cancers and one family of patent applications co-owned with BeiGene directed to combination 
therapies for the treatment of solid tumors. This intellectual property portfolio comprises four 
issued U.S. patents which are expected to expire in 2038, 12 pending U.S. patent applications, 
which if issued, are expected to expire 2037 through 2044, two international PCT applications, 
54 pending foreign applications and 12 issued patents in foreign jurisdictions.

Akili is pioneering the development of cognitive treatments through game-changing 
technologies. Akili’s EndeavorRx®1 is an FDA-cleared digital therapeutic indicated to improve 
attention function as measured by computer-based testing in children ages 8-17 years old 
with primarily inattentive or combined-type ADHD, who have a demonstrated attention issue. 
Akili’s EndeavorOTC®2 is a digital therapeutic indicated to improve attention function, ADHD 
symptoms and quality of life in adults 18 years of age and older with primarily inattentive or 
combined-type ADHD.

 — We engaged with leading neuroscientists and clinicians who had been studying the effects of 

video games on cognition and the underlying neural processes accessible by sensory stimulation 
and we collaborated with Dr. Adam Gazzaley, M.D., Ph.D., to translate the underlying academic 
device into a medical intervention, including overseeing the initial product development and 
design and the implementation of the initial proof-of-concept studies.

 — Akili’s FDA-cleared product, EndeavorRx, is based on a patented platform technology 

exclusively licensed from the University of California, San Francisco. The proprietary platform 
targets cognitive interference processing while also adapting difficulty automatically in real-
time, allowing individuals of wide-ranging ability levels to interact with the product in their homes 
without the need for physician calibration or additional hardware. 

 — In September 2023, Akili announced its strategic plan to transition from a prescription to 

a non-prescription business model. The non-prescription model allows Akili to give consumers 
access to differentiated and clinically-validated technology, while removing the reliance on 
payers that stand in the way of patients trying to access treatment. 

 — In January 2023, Akili shared topline results of the STARS-ADHD-Adolescents label expansion trial 
evaluating the efficacy and safety of EndeavorRx in adolescents ages 13-17 with ADHD. The pivotal 
trial achieved its predefined primary efficacy outcome, showing statistically significant improvement 
in attentional functioning after four weeks of treatment. Based on these results, Akili announced in 
December 2023 that it received authorization from the FDA to expand the EndeavorRx label to 
include older children aged 13-17. This increased age range is expected to more than double the 
number of pediatric patients with ADHD who are now eligible for EndeavorRx. 

 — In May 2023, Akili shared topline results of the STARS-ADHD-Adult clinical trial evaluating the 
efficacy and safety of EndeavorRx in adults with ADHD. The results demonstrated attention 
improved in more than 80 percent of adults with ADHD, and over one-third of participants no 
longer exhibited an attention deficit following treatment. Improvements in attention were nearly 
seven times larger than those seen in the pivotal trial that supported EndeavorRx’s FDA 
authorization for aged 8 to 12 with ADHD. Additionally, nearly half of adults treated with 
EndeavorRx met a prespecified threshold for clinically meaningful improvement in their quality 
of life. EndeavorRx treatment was well-tolerated, with minimal side effects and no serious 
device-related adverse events reported. Based on these results, Akili announced the release of 
EndeavorOTC in June 2023, and submitted a 510(k) application to the FDA in October for 
EndeavorOTC as an over-the-counter (OTC) treatment for adults with ADHD.

 — In the February 2024 post-period, Akili shared positive results from its partner Shionogi’s Phase 3 
pivotal trial of its localized version of Akili’s EndeavorRx for pediatric ADHD patients in Japan 
aged 8 to 17. Shionogi submitted the results of this trial for regulatory approval to Japan’s 
Pharmaceuticals and Medical Devices Agency in 2024.

 — Akili plans to pursue regulatory approval for OTC labeling of its treatment products and expects that 
both EndeavorOTC and EndeavorRx will remain on the market as the company pursues these plans.

 — EndeavorOTC: Akili continues to work interactively with FDA on the review of its marketing 

submission for EndeavorOTC and expects to provide a status update by the end of the second 
quarter of 2024. Pursuant to FDA guidance, Akili is continuing to make EndeavorOTC available 
over the counter, without a prescription, while its submission to FDA is under review.
 — EndeavorRx: Akili announced plans to submit data to the FDA to convert its pediatric 

prescription product, EndeavorRx, to OTC in 2024. Akili’s partner Shionogi submitted the 
localized Japanese version of Akili’s AKL-T01 (marketed as EndeavorRx in the U.S.) for marketing 
approval with Japan’s Pharmaceuticals and Medical Devices Agency.

 EndeavorRx is a digital therapeutic indicated to improve attention function as measured by computer-based testing in children ages 8-17 years old with primarily inattentive 
or combined-type ADHD, who have a demonstrated attention issue. Patients who engage with EndeavorRx demonstrate improvements in a digitally assessed measure Test of 
Variables of Attention (TOVA®) of sustained and selective attention and may not display benefits in typical behavioral symptoms, such as hyperactivity. EndeavorRx should be 
considered for use as part of a therapeutic program that may include clinician-directed therapy, medication, and/or educational programs, which further address symptoms of the 
disorder. EndeavorRx is available by prescription only. It is not intended to be used as a stand-alone therapeutic and is not a substitution for a child’s medication. The most common 
side effect observed in children in EndeavorRx’s clinical trials was a feeling of frustration, as the game can be quite challenging at times. No serious adverse events were associated 
with its use. EndeavorRx is recommended to be used for approximately 25 minutes a day, 5 days a week, over initially at least 4 consecutive weeks, or as recommended by your child’s 
health care provider. To learn more about EndeavorRx, please visit EndeavorRx.com.

2  EndeavorOTC is a digital therapeutic indicated to improve attention function, ADHD symptoms and quality of life in adults 18 years of age and older with primarily inattentive or 

combined-type ADHD. EndeavorOTC utilizes the same proprietary technology underlying EndeavorRx, a prescription digital therapeutic indicated to improve attention function 
in children ages 8 - 17. EndeavorOTC is available under the U.S. Food and Drug Administration’s current Enforcement Policy for Digital Health Devices for Treating Psychiatric 
Disorders During the Coronavirus Disease 2019 (COVID-19) Public Health Emergency. EndeavorOTC has not been cleared or authorized by the U.S. Food and Drug Administration 
for its indications. It is recommended that patients speak to their health care provider before starting EndeavorOTC treatment. No serious adverse events have been reported in any 
of our clinical studies. To learn more, visit EndeavorOTC.com.

Vor Bio is a clinical-stage cell and genome engineering company that aims to change the 
standard of care for patients with blood cancers by engineering hematopoietic stem 
cells (HSC) to enable targeted therapies post-transplant. Vor’s lead eHSC candidate 
is tremtelectogene empogeditemcel (trem-cel), formerly VOR33, which is created by 
genetically modifying healthy donor HSCs in order to remove the CD33 surface target 
protecting them from a targeted therapy post-transplant. Transplant with trem-cel is 
designed to replace standard of care transplants for patients suffering from acute myeloid 
leukemia (AML) and potentially other blood cancers. Trem-cel has the potential to enable 
powerful targeted therapies in the post-transplant setting including CD33-targeted CAR-T 
cells. VCAR33ALLO is a CD33-directed CAR-T cell therapy made from healthy cells obtained 
from the same donor from which the patient was previously transplanted. Vor’s vision is 
to develop a treatment system for AML where trem-cel is first administered to patients to 
remove CD33 from their healthy cells, followed by VCAR33ALLO administration to target and 
kill any remaining cancer cells.

 — We were interested in approaches to treat hematological malignancies that currently have poor 
response rates or poor adverse event profiles despite recent advances in cell therapies and 
targeted therapies. We worked with Vor Bio Scientific Board Chair, Siddhartha Mukherjee, M.D., 
Ph.D., on key intellectual property, which Vor Bio exclusively in-licensed from Columbia, and on 
advancing this concept through critical proof-of-concept experiments.

 — In the March 2024 post-period, Vor announced that the FDA had granted Fast Track Designation 

and Orphan Drug Designation to VCAR33ALLO.

 — In the January 2024 post-period, Vor announced it has dosed the first patient in VBP301, its 

Phase 1/2, multicenter, open-label, first-in-human study of VCAR33ALLO in patients with relapsed 
or refractory AML after standard-of-care transplant or a trem-cel transplant. By using healthy 
transplant donor cells as the starting material to produce VCAR33ALLO, the CAR-T cells have 
a more stem-like phenotype, leading to greater potential for expansion, persistence, and 
anti-leukemia activity compared to a product derived from a patient’s own lymphocytes. 

 — In November 2023, Vor announced updated data from patients treated in VBP101, Vor’s 

Phase 1/2a multicenter, open-label, first-in-human study of trem-cell in patients with AML. 
Primary neutrophil engraftment occurred in all seven patients treated to date with trem-cel with 
a median time to engraftment of 10 days. All three patients treated with Mylotarg (the only 
anti-CD33 therapy approved by the FDA) experienced hematologic protection from deep 
cytopenias through repeat doses, suggesting that trem-cel transplants shielded patients’ 
healthy cells from the on-target toxicity (myelosuppression) typically seen with Mylotarg 
treatment. The hematological protection exhibited provides support that dose escalation of 
Mylotarg is warranted and highlights the potential to dose CD33-targeted CAR-T therapy 
without expected hematologic toxicity.

 — In August 2023, Vor announced a world-wide non-exclusive license from Editas Medicine for 

ex-vivo Cas9 gene-edited HSC therapies for the treatment and/or prevention of hematological 
malignancies.

Expected milestones

 — A trem-cel clinical trial data update is expected in the second half of 2024.
 — A VCAR33ALLO clinical trial data update is expected in the second half of 2024.

Vedanta is leading the development of a potential new category of oral therapies based 
on defined consortia of bacteria isolated from the human microbiome and grown from 
pure clonal banks. Vedanta is a leader in the field with capabilities and deep expertise to 
discover, develop and manufacture live bacteria-based therapies. Vedanta’s candidates 
include VE303, a Phase 3-ready therapeutic candidate designed for the prevention of 
recurrent Clostridioides difficile infection (rCDI), VE202, a Phase 2 therapeutic candidate 
in development for the treatment of ulcerative colitis and VE707, a preclinical therapeutic 
candidate being advanced for the prevention of infection and colonization recurrence of 
several multidrug-resistant organisms (MDROs).

 — We engaged with leading world-renowned experts in immunology and identified and in-

licensed intellectual property to pioneer the concept of therapeutically defined consortia of 
microbes that could modulate the immune system or treat bacterial infections.

 — In October 2023, Vedanta announced the first patient was dosed in the Phase 2 COLLECTiVE202 
clinical trial of VE202 for the treatment of ulcerative colitis. Vedanta also announced that the U.S. 
Food and Drug Administration granted Fast Track designation to VE202.

 — In October 2023, Vedanta shared additional data from the VE303 Phase 2 CONSORTIUM 

clinical trial that further explained the biological effects of VE303 associated with prevention 
of Clostridioides difficile recurrence. VE303 accelerated the restoration of a healthy gut 
microbiome community and early recovery of key metabolites. Furthermore, among nearly 
400 bacterial species detected in trial participants after treatment, species in VE303 were 
the top predictors of non-recurrence. Vedanta previously announced that the trial met its 
primary endpoint.

 — In October 2023, Vedanta shared preclinical data of VE707, which demonstrated that among 
nearly 100 consortia tested for their ability to reduce intestinal carriage of some of the most 
common and serious MDROs, VE707 was the most effective at reducing the levels of K. 
pneumoniae and E. coli in rodent models. Results also demonstrated that a rationally designed, 
defined consortium of bacteria can decolonize MDROs in animals and can be manufactured 
efficiently.

 — In May 2023, Vedanta announced the U.S. FDA granted Fast Track designation to VE303, for the 

prevention of rCDI.

 — In April 2023, Vedanta announced a $106.5 million financing to advance its pipeline of defined 

bacterial consortia therapies.

Expected milestones

 — Vedanta plans to initiate a Phase 3 clinical trial of VE303 in patients at high risk for rCDI in the first 

half of 2024.

Sonde is developing a voice-based artificial intelligence platform that detects changes in the 
sound of voice that are linked to health conditions – like depression, anxiety and respiratory 
disease – to provide health tracking and monitoring. 

 — We identified vocal features as a leading non-invasive source of health data, particularly given the 
evolving technology landscape where voice interactions with devices are rapidly increasing. We 
developed novel intellectual property around this concept and helped advance the technology 
from an academic concept to a commercially focused technology.

 — In the March 2024 post-period, Sonde announced the publication of a new study that has 

validated the ability of the company’s mental fitness vocal biomarker (MFVB) platform to reliably 
distinguish individuals with elevated mental health symptoms. The four-week cohort study 
revealed a statistically significant correlation between voice-based identification of increased or 
decreased mental health risk with the results of the M3 Checklist, a clinically validated mental 
health assessment. The research, published in the peer-reviewed journal Frontiers in Psychiatry, 
highlights the potential of vocal biomarkers and Sonde’s technology specifically to provide 
objective data that can complement clinical care and improve self-monitoring for conditions like 
depression, stress- and trauma-related conditions, and anxiety.

 — In May 2023, Sonde announced the publication of new research that demonstrates the ability of 

its respiratory responsive vocal biomarker (RRVB) machine learning model to differentiate 
patients with COVID-19 from healthy individuals with about 70% accuracy. The peer-reviewed 
study, which was published in the Journal of Medical Internet Research, suggests the RRVB tool 
could serve as a pre-screening tool for acute respiratory infection and pave the way for the 
development of voice-based tools for future disease detection and monitoring applications.
 — In February 2023, Sonde and the Massachusetts General Hospital Frontotemporal Disorders 
Unit announced they had been selected by the Massachusetts Artificial Intelligence and 
Technology Center for Connected Care in Aging & Alzheimer’s Disease (MassAITC) to lead 
a pilot study focused on leveraging vocal biomarkers for remote detection and monitoring of 
mild cognitive impairment in the home environment. Funded by MassAITC and the National 
Institute on Aging, a division of the U.S. National Institutes of Health, the project is part of 
a $1.7 million grant to explore the use of artificial intelligence and other advanced technologies 
for in-home care. Specifically, it will evaluate the feasibility of obtaining voice recordings of older 
individuals in the home environment that can be used to longitudinally monitor speech and 
memory functions.

Expected milestones

 — Sonde is working to develop a cognitive fitness or Mild Cognitive Impairment vocal biomarker 

health tracking capability by late 2024.

Entrega is focused on the oral administration of biologics, vaccines and other drugs that 
are otherwise not efficiently absorbed when taken orally. The vast majority of biologic 
drugs, including peptides, proteins and other macromolecules, are currently administered 
by injection, which can present challenges for healthcare administration and compliance 
with treatment regimes. Entrega believes oral administration thus represents an ideal 
administration approach for this increasingly large class of therapies reshaping many areas of 
medicine, including the treatment of diabetes and weight loss.

Entrega’s technology platform is an innovative approach to oral administration which uses 
a proprietary, customizable hydrogel dosage form to control local fluid microenvironments 
in the GI tract in an effort to both enhance absorption and reduce the variability of drug 
exposure. Peptide therapeutics (e.g., the emerging GLP-1 agonist class) are ideally suited to 
benefit from Entrega’s approach.

 — We were interested in enabling the oral administration of biologics, which has been a long-

standing problem in drug development. We engaged with leading experts in drug 
administration, including Robert Langer, Sc.D., screened over 100 technologies and the initial 
platform was licensed from Samir Mitragotri, Ph.D., when he was Professor of Chemical 
Engineering at UC Santa Barbara (currently Hiller Professor of Bioengineering and Hansjorg Wyss 
Professor of Biologically Inspired Engineering at Harvard University). We later enhanced this 
platform with intellectual property developed by our team.

 — In 2023, Entrega demonstrated increased oral peptide bioavailability of two- to three-fold over 

standard permeation enhancer formulations.

on the US Bureau of Labor Statistics.6 
We are proud to have 43% gender 
diversity at the Board level, which 
placed PureTech within the top 30 
FTSE250 companies.7

Goal 9: Build resilient infrastructure, 
promote inclusive and sustainable 
industrialization and foster 
innovation
Industry, infrastructure and innovation 
are key drivers of economic growth and 
social value creation. Innovation sits at 
the heart of what we do at PureTech, 
and our success is a natural result of our 
innovative and strong R&D model (see

based on our leading research from 
scientific collaborators and our 
innovative R&D expertise.

Goal 10: Reduce inequality within and 
among countries
We believe that equality is fundamental 
to a stable, just, prosperous and 
peaceful society and we recognize the 
important role we can play in 
addressing systemic inequality both 
within our industry and beyond.

We have implemented a series of 
policies and practices to support equal 
opportunity and treatment of all our 
staff. We have a zero-tolerance policy 
on discrimination in all its forms and 
expect our value chain partners to do 
the same (see page 35).

Goal 8: Promote sustained, inclusive 
and sustainable economic growth, 
full and productive employment and 
decent work for all
We support our staff by ensuring 
excellent working conditions and 
offering a comprehensive benefits 
package to all employees across our 
business operations (see page 37).

We provide in-depth training to our 
people, with a strong focus on 
improving their skills by putting in place 
effective career development plans. 
We also drive significant economic 
growth and productivity through our 
R&D and growing business 
investments. Finally, we partner with 
local universities to provide internship 
opportunities for students who want to 
pursue a career in life sciences 
(see page 36).

Goal 12: Ensure sustainable 
consumption and production patterns
Responsible consumption and 
production are fundamental to 
sustainable development. We engage 
with external experts, including 
a Ecovadis Silver rated sustainable 
environmental solutions provider to 
monitor and manage waste with 
a particular focus on hazardous medical 
waste management. The majority of our 
biologically and chemically hazardous 
waste is disposed of through conversion

facing our world today, with severe and 
underreported implications for human 
health. At PureTech, we monitor and 
report our scope 1, 2 and 3 emissions 
and we recognize that the ability to 
manage the potential impacts of 
climate change on our business and 
strategic plans are among the factors 
that are integral to the long-term 
success of our business. To take this 
a step further, we undertook a detailed 
analysis to identify any climate-related 
risks with the potential to have 
a strategic impact on our business 
moving forward and have published our 
inaugural Task Force on Climate-
Related Financial Disclosures (TCFD) 
disclosure in 2021 (see pages 54 to 58 
for our 2023 TCFD disclosures).

We remain committed to assessing, 
measuring and reporting climate 
exposure and continuing to support 
high level partnerships and industry 
associations advocating for responsible 
public policies on climate.

Goal 17: Strengthen the means of 
implementation and revitalize the 
global partnership for sustainable 
development
At PureTech, we recognize the 
importance of building partnerships 
and collaborations to drive progress on 
the Sustainable Development Goals.

We are Committed to the 
Fight Against Idiopathic 
Pulmonary Fibrosis (IPF)
It’s important to note that the work we 
do at PureTech every day is in service 
to the patients we hope to help. Our 
most advanced therapeutic candidate, 
LYT-100, is being developed for the 
potential treatment of conditions 
involving inflammation and fibrosis, 
including IPF. IPF is a progressive and 
life-shortening disorder of the lungs with 
a median survival rate of 2-5 years.8

Our initiatives:
Our awareness campaign to informs IPF patients and caregivers 
worldwide of our investigational treatment in development. Our 
initiative creates inclusive resources to engage both patients and 
caregivers in clinical trials.

In September 2023, we continued our efforts to promote 
Pulmonary Fibrosis Awareness Month to raise awareness of IPF 
and to serve as inspiration for our employees. During this month 
we hosted a lunch and learn with Dr. Lisa Lancaster to understand 
the evolution of IPF trials and the patient experience. During an 
employee town hall, members of the Social and Culture 
Committee led the discussion on IPF and conducted the ‘Pucker 
Up Challenge”. We also held an all-employee walk in taking steps 
toward a cure. 

In February 2023, we celebrated Rare Disease Day in which 
employees wore stripes to show support for rare diseases such as 
IPF. The idea is to raise awareness for the over 7,000 rare diseases 
that impact millions of people globally and to advocate for 
health equity.

Consistent with our commitment to improve the care of patients 
with IPF, we partnered with the Pulmonary Fibrosis Foundation 
(PFF) in 2023 to help raise awareness of the condition in 
several ways.

We have a strong relationship with PFF, which is the leading 
patient advocacy organization for the IPF community. They not 
only provide support and educational resources to the 
community but are also working to identify effective treatments 
for IPF. PFF is also a trusted resource and partner to PureTech as 
we advance LYT-100 through the clinic.

In November 2023, we established an educational grant 
partnership with PF Warriors to advance their awareness, 
education and clinical research initiatives for pulmonary fibrosis 
patients. PF Warriors is an international support network 
delivering vital assistance, education, inspiration and hope to 
pulmonary fibrosis patients and families. Through such strategic 
alliances, we aim to empower patient advocacy groups creating 
real change for those living with PF. Our grant upholds our 
commitment to foster greater understanding of this disease while 
accelerating essential efforts to improve patient 
health outcomes.

Patients

Clinical trial participants are made fully aware of all risks involved 
prior to participating in a clinical trial. To confirm this, we ensure 
that every patient has provided informed consent of their 
willingness to participate through a signed voluntary 
commitment. Our informed consent requirements are set out in 
the PureTech Clinical Research Policy.

We also rely on the use of human biological specimens to develop 
our innovative therapies through clinical trials, which require 
informed consent. Our Human Biological Specimens Policy 
specifies our commitment to respecting both donors and the 
specimens they provide and that collecting, obtaining, storing 
and using human biological samples must be obtained 
through consent. 

Our President is responsible for ensuring that PureTech follows all 
US and applicable international regulatory requirements and 
standards and applicable bioethics principles. In 2023, there were 
no FDA sponsored inspections related to clinical trial 
management and pharmacovigilance that resulted in PureTech 
receiving Voluntary Action Indicated (VAI) and Official Action 
Indicated (OAI) from FDA.

Bioethics: R&D
Our ethical and quality management standards, allow for 
continuous improvement through R&D, while helping us to 
maintain high standards of product quality and safety in 
compliance with relevant regulations at each phase. In 2023, we 
spent $110.5 million on research and development projects to 
develop new and innovative therapeutics (see page 73 for details 
on R&D expenses)

As we enhance our R&D strategy, we continue to assess and 
identify areas for improvement across our clinical trial safety, 
quality and risk management processes. We have robust policies 
relating to Good Manufacturing Practices (GMP) and regulatory 
inspections to reinforce ethics into our processes and we are in 
the process of implementing additional policies on quality and 
risk management.

Environmental factors remain integral in our R&D as we aim to cut 
back or remove hazardous chemicals from our R&D procedures. 
We also stay current on the newest green chemistry 
advancements and strive to implement eco-friendly design 
principles. In 2023, we managed to optimize some of our 
large-scale drug substance processes to replace more hazardous 
solvents that negatively impact the environment.

P

Our team is dedicated to providing therapeutics for unmet 
medical needs. We leverage the substantial groundwork laid by 
the biopharmaceutical industry, which has dedicated decades to 
discovering novel modalities and proving efficacy in patients. 
Despite these advancements, barriers have prevented important 
new medicines from reaching their full potential. Through our 
unique insights, we aim to realize the full promise of these vital 
new therapeutics for patients in need. With our cutting-edge 
R&D efforts, we are targeting these gaps while creating long-
term value for both patients and shareholders.

Commitment #2: 
Ensuring patient safety

Patient safety remains our utmost priority informing all aspects of 
our work. Our committed research team, in conjunction with 
external partners, adheres to strict procedures, processes and 
guidelines to ensure clinical trial and R&D integrity. Through 
diligent oversight and responsible development practices, we 
seek to uphold patient wellbeing at every stage.

Delivering Safe Clinical trials
We conduct all clinical trials according to the highest standards of 
ethics and safety. All our trials follow the standards of the 
International Conference on Harmonization (ICH) Good Clinical 
Practice guidelines and the World Medical Association (WMA) 
Declaration of Helsinki on the Ethical Principles for Medical 
Research Involving Human Subjects.

To ensure compliance and rigor in our approach, we seek 
approval from Independent Ethics Committees and local 
regulatory authorities on all investigative medicine trials. In 
addition, our employees who are engaged with clinical trials, 
either as clinical staff or their designees, are responsible for 
ensuring full compliance with best clinical practice.

When sponsoring an Investigational New Drug (IND) application, 
we acknowledge our responsibility to both participants and the 
regulatory agencies who put their trust in us to act responsibly. 
We have a robust governance framework in place to ensure 
patient oversight which includes effective policies and protocols 
such as our Safety Management Plans and Medical Monitoring 
Plans, which helps us to monitor, review and act on any incidents. 
All protocols are compliant with ICH E6 (R2) per FDA regulations 
and most of our studies have Independent Data Safety 
Monitoring Committees.

Our ESG framework continuedESG reportPureTech Health plc   Annual Report and Accounts 2023    33  

Bioethics: Animal Research
Animal research continues to play a vital and irreplaceable part in 
progressing drug discovery, as it assists scientists in addressing 
biological uncertainties.

Ensuring Drug Efficacy and Safety

Therefore, in 2023, PureTech received no FDA warning letters, no 
products were delayed due to a lack of regulatory approval and 
no product recalls took place.

As we continue to advance our therapeutic candidates towards 
commercialization, we will continue to practice our clinical 
protocols diligently to ensure ongoing safety and compliance 
across our operations and clinical trials.

Commitment #3: 
Accelerating our R&D engine to unlock new medicines

R&D has been the bedrock of progress in global health and a key 
component in the successful discovery and development of our 
therapeutic candidates. 

Generating a robust pipeline that has the potential to 
address millions of patients with unmet medical needs has been 
made possible through our strong R&D model.

We are proud of our model which allows us to fulfill our unyielding 
commitment to delivering potentially life-changing new 
therapies for patients in need. We will continue to leverage this 
model, our scientific insight and our network of scientists, 
clinicians and industry leaders to unlock new medicines and 
deliver highly innovative therapeutics for patients.

PureTech conducts animal testing only when necessary, in line 
with the FDA Modernization Act 2.0, to further the development 
of therapeutics and is mandated by regulatory bodies, before 
human trials of new medications can proceed.

We follow the guidelines outlined under the USDA Animal 
Welfare Act and are dedicated to the human and ethical 
treatment of animals. Studies involving animals are evaluated and 
approved by the Executive Team and are carried out at external 
qualified and certified vendors that fulfil our standards and 
anticipated practices for animal care, welfare and handling.

Whenever we contemplate animal testing, we are devoted to 
applying the replacement, reduction and refinement of animal 
studies (3Rs).

 —  Replace 

We use alternative methods to animal testing 
wherever possible.

 — Reduce 

We use the minimum number of animals in trials.

 — Refine 

We minimize pain, suffering and distress, and improve the 
welfare of animals used in trials.

Bioethics: Quality Management
We have a robust Quality Management System (QMS) in place to 
oversee our raw material suppliers. Our QMS consists of various 
SOPs which describe our controlled processes that result in 
consistent quality control as per PureTech’s quality system. SOPs 
include, but are not limited to, the processes relating to the:

 —  Qualification of New Vendors
 — Qualification of Existing Vendor for New Materials
 — Management of Changes related to Vendor
 — Evaluation of Supply for Quality
 — Change Control
 — Batch Disposition
 — Employee Training on New Materials

To ensure our QMS is robust and up to date, risk assessment 
protocol is built into our procedures for vendor audits, vendor 
oversight, and data integrity for Chemistry, Manufacturing, and 
Controls (CMC). This allows us to quickly determine vendor risks 
and accelerate new vendor onboarding to meet 
business demands.

Our detailed Board and Executive Management diversity data is 
set out in page 53 of this report as required by the Listing Rules 
LR 9.8.6(10) Annex 2.1. Data is for the PureTech Board and 
Executive Management as of December 31st, 2023. Numbers in 
this table are based on how individuals identify themselves.

Promoting Cultural Diversity
It is important to us that alongside our efforts to champion 
gender equality, we promote and celebrate cultural diversity 
within our firm and the communities we serve. 

We are compliant with the US Equal Employment Opportunity 
Commission’s requirement to file an annual EEO-1 Report, 
disclosing employment data about job categories as well as the 
ethnicity, race and gender of our employees. This process 
ensures that we maintain transparency and accountability across 
our business and allows us to identify target areas for further 
improvement regarding diversity, equity and inclusion. 

In 2023, our employee-led Cultural and Social Committee 
continued its work to support the enhancement of cultural 
diversity in our workplace. Established in 2021, this collaborative 
committee dedicates itself to creating programs that celebrate 
diversity, promote equality, and foster respect and inclusion. 

Examples of the Committee’s initiatives in 2023 included:

Marking International Women’s Day
In March, we celebrated International Women’s Day, a global day 
dedicated to recognizing the social, economic, cultural, and 
political achievements of women. To mark this occasion, we 
circulated company-wide educational materials and event 
resources, to help colleagues learn more about the history of 
women’s rights and their invaluable contributions to society, as well 
as current ways in which colleagues can get involved in supporting 
this mission. We are proud to play our part in this important global 
initiative by commemorating women’s achievements, raising 
awareness about discrimination, and encouraging action to drive 
gender parity.

Celebrating LGBTQ+ Pride Month 
In June, we marked LGBTQ+ Pride Month by celebrating the 
profound impact lesbian, gay, bisexual, and transgender 
(LGBTQ+) individuals have made in past and continue to make on 
our present and future. Throughout the month we celebrated in 
many ways, including: 

Commitment #1: 
Building a diverse, equitable and inclusive workplace

Diversity, Equity and Inclusion
We know that the best ideas are brought to life when we combine 
our different perspectives, talents and skills to unlock our 
maximum potential as an organization. That is why we value having 
a diverse, equitable and inclusive work environment in which all our 
colleagues are treated with utmost fairness, kindness, and respect. 

Under PureTech’s Formal Policy, we are strictly committed to 
treating all employees and qualified applicants equally 
regardless of their race, color, religion, gender or gender identity, 
sexual orientation, nationality, ancestry, age, physical or mental 
disability, veteran or military service, or any other status 
protected by law.

Our commitment to diversity, equity and inclusion is embedded 
across every aspect of our employment practices and 
encompasses all stages from hiring, job assignment, promotion 
and compensation to discipline, discharge, benefits and training.

Championing Gender Diversity
For us at PureTech, it is a deep source of pride that we champion 
gender diversity and equality in the medical industry, as well as in 
our workplace. 

We are strongly committed to promoting diverse teams across 
both our leadership and employee level, to ensure an equitable 
environment in the business. We are consistently taking 
significant steps forward in integrating diversity at a leadership 
level, as we believe that a diverse board and senior management 
team leads to stronger performance, retention of exceptional 
talent and greater shareholder value.

We have achieved gender parity at Board level as of December 31, 
2023, with 43% women and 57% men making up our senior 
leadership team, whilst also continuing to enhance the gender and 
cultural diversity of our wider management team and workforce.

Commemorating Juneteenth 
In June 2023, we honoured Juneteenth, the day dedicated to 
commemorating the emancipation of slavery in the US. To learn 
more about the legacy of this historical event, we distributed 
resources to employees highlighting the context, events and 
significance of Juneteenth. In addition to this, we supported local 
African-American businesses through catering orders for 
company events. As of 2023, we have also added June 19th as 
a company holiday to observe this important day in history.

Commitment #2: 
Promoting employee development to attract and retain the  
best talent

Human capital is vital to a successful business operation to 
identify new opportunities, innovate and lead. We depend on our 
people, their scientific knowledge, skills and commitment to 
thrive. As such, the personal development, retention and 
recruitment of industry-leading talent is one of our top priorities 
at PureTech.

Recruitment and Retention
As our programs advance and our business rapidly evolves, the 
PureTech team has evolved with it over the course of years. While 
the prioritization of our pipeline led to a scale-back of our R&D 
operations in 2023, our recruitment strategy remains unchanged, 
as we continue to focus on developing a skilled and diverse 
pipeline of talent.

Beyond this, we are passionate about providing opportunities to 
those hoping to pursue a career in life sciences. To support 
first-generation students from under- resourced and under-
represented communities, we partner with local organizations 
like Project Onramp to offer paid summer internships. In 2023, 
we welcomed 4 interns through our various programs.

Training and Development
We uphold the value of human capital development at PureTech, 
encouraging managers and employees to discuss job 
performance and goals on an informal, day-to-day basis while 
also conducting formal performance evaluations annually. We 
encourage regular one-on-ones between employees and their 
supervisors, and progress is monitored via an online portal. This 
enables employees and managers to have clear visibility over 
their goals throughout the year, which in turn facilitates ongoing 
constructive feedback and development. In 2023, 100% of our 
employees received performance appraisals.

For PureTech, career development goes beyond providing 
opportunities for promotions. We believe an effective career 
development program entails providing opportunities to enhance 
employees’ competitive capabilities, broaden their expertise and 
deepen their knowledge. To achieve this, we offer an extensive 
range of training and also fund participations in development 
programs on a case-by-case basis. Some of the development 
trainings include:

IT training:
 — Mandatory annual IT training provided by Risk Management 

Solutions (RMS) for all employees

 — Mandatory annual cybersecurity training for all employees, 

with follow- on assignment to be completed

We source our talent through our outstanding network of world 
leading scientists. We also source emerging talent from local top 
tier universities in Boston – the heart of the world’s biotech hub – 
as well as through partnerships with local university cooperative 
education programs. Our engagement in cooperative education 
programs offers students real-world experience aligned with 
their academic pursuits. By welcoming undergraduate co-op 
students for six-month paid internships in our Research 
department, we continue to fortify our talent acquisition pipeline. 
Additionally, active participation in life science career fairs 
enables us to identify and attract skilled candidates, ensuring we 
have a strongly dynamic team working towards our innovative and 
sustainable initiatives.

Employee Benefits
The physical, financial, social and emotional well-being of our 
employees is paramount to us at PureTech. To support this, we 
provide a range of benefits for our employees.

An enrollment session is held annually with our benefits 
administrator, Baystate Benefit Services, to help our employees 
understand how they can make best use of the benefits available

PureTech’s performance share plan provides the majority of 
employees stock options upon joining the organization.

We also provide appropriate market-based compensation and 
incentives in alignment with the goals of the organization and its 
shareholders.

As of 2023, our company does not have any employees who are 
covered by collective bargaining agreements or are affiliated with 
trade or labour unions. While we currently operate without such 
arrangements, we respect the rights of our employees, and 
support their freedom of association and the option 
collective bargaining.

Commitment #3: 
Maintaining a robust Employee Health and Safety (EHS) program

P

l

It is our unyielding commitment to provide a healthy and safe 
working environment for our employees that supports their 
physical and mental wellbeing. Amid the challenges posed by the 
COVID-19 pandemic, our unwavering commitment to employee 
well-being has been paramount. We continue to prioritize the 
health and safety of our team, alongside implementing 
comprehensive and regularly updated action plans to ensure 
business continuity. In 2023, we have continued to evolve our 
COVID-19 practices in response to guidance from scientific 
communities and local/national government. We monitor the 
local and national COVID-19 levels to ensure our practices keep 
staff safe. We provide all staff access to free COVID tests and 
masks to be used when the individual deems it necessary. Onsite 
staff are encouraged to use our hybrid working model when they 
are not feeling well. 

EHS Governance
We have a robust Employee Health and Safety program in place 
that ensures adherence to all EHS-related activities including 
employee safety training, lab safety protocols and emergency 
action planning.

Our EHS activities are overseen by an Emergency Coordinator 
and Safety Officer with support from an external EHS expert who 
is certified through the National Registry of Certified 
Microbiologists (NRCM) and is a Certified Biosafety Professional 
(CBSP) and Registered Biosafety Professional (RBP) through the 
American Biological Safety Association (ABSA).

PureTech’s EHS team is led by a Safety Officer and Emergency 
Coordinator per the requirements of OSHA. The roles and the 
responsibilities involved are as follows:

Safety Officer
 — Fulfils the role of Chemical Hygiene Officer (CHO). Appointed 
under the Chemical Hygiene Plan, the CHO is responsible for 
designing, developing, implementing, and maintaining the 
Company’s chemical hygiene policies and practices. They are 
also responsible for ensuring appropriate safety procedures 
and training are in place and ensuring that all hazardous waste 
is disposed of correctly.

Emergency Coordinator 
 — The role involves keeping PureTech’s Emergency Plan up to 

date and reviewing and amending it where necessary.

Our ESG framework continuedESG report38    PureTech Health plc   Annual Report and Accounts 2023

People

As well as overseeing day-to-day activities, the EHS team reviews 
EHS protocols on an annual basis, or when emerging reasons 
demand a process review, such as a lab incident, new project, or 
the introduction of a new piece of equipment.

Commitment #4: 
Strengthening engagement and collaboration between people, 
communities and partners

EHS Training and Audits
We provide a mandatory safety training program for all our staff 
and conduct regular internal audits to maintain industry- leading 
health and safety (H&S) standards. Our H&S training modules 
consist of the following to integrate and maintain highly effective 
H&S culture:

 — Mandatory annual safety training provided to all lab 

employees in accordance with the Occupational Safety 
and Health Administration (OSHA)

 — Mandatory refresher Personal Protective Equipment (PPE) 

training provided to all lab staff

 — Mandatory RCRA hazardous waste refresher training 

provided to all lab staff

Key safety information is communicated to employees through 
regular internal communication channels such as town hall 
meetings, bulletin boards, memoranda, and other written 
internal communications. Employees must report any concerns 
to a supervisor or PureTech’s operations team.

Reporting on Incidents
PureTech’s operation is classified as a ‘research and development 
laboratory’ according to the Standard Industrial Classification 
(SIC) or North American Industrial Classification System (NAICS) 
codes and hence we are exempt from reporting on incidents to 
OSHA. With that said, we continue to practice thorough safety 
protocols at our lab facilities and are committed to continuously 
improving our EHS measures driven by our Safety Committee.

Stakeholder engagement and collaboration is the foundation of 
innovation and key to unlocking new solutions that profoundly 
transform the lives of patients. 

As such, we take great care to invest in and promote a positive 
and interconnected company culture among our stakeholders, 
while ensuring we make a meaningful difference to the 
communities closest to us.

Employee Engagement 
We are proud of our series of initiatives to promote employee 
engagement, which are met with resounding enthusiasm and 
appreciation from our colleagues: 

Employee Intranet, a Connection Hub
 — Our Employee Intranet features important company 

information and employee resources in one easily accessible 
portal, including company news, new hire highlights, 
upcoming company events, employee directory, a social 
gallery and an opportunity to provide feedback.

Employee Value Recognition
 — In 2023, we added an Employee Value Recognition section to 
the Employee Intranet platform, providing employees with 
the opportunity to nominate their colleagues for their hard 
work and recognize the ways in which they uphold PureTech’s 
core values. All submitted value recognitions are then shared 
and celebrated at the following companywide town hall. 

Employee-led Cultural and Social Committee
 — Our dedicated Cultural and Social Committee, run by our 

employees, plan and host D&I-related programs and events, 
with the aim of fostering engagement and cementing a sense 
of community and belonging for our people.

Employee Engagement
 — We have an open-door policy to encourage employee 

feedback and to better understand our employees’ needs, 
concerns, and satisfaction rate. In 2023, we held a series of 
employee value and cultural workshops during a company 
retreat. See more in Employee Retreat.

Community Engagement
As a longstanding member of Boston’s thriving biotech hub, we 
are committed to giving back to our community in as many ways 
as we can, to help make a difference. In 2023, we contributed to 
several community initiatives and charitable events, 
which included:

The Greater Boston Food Bank – Hunger Free Holidays 
Campaign
 — In November 2023, we participated in a fundraiser for the 
Hunger Free Holidays campaign hosted by the Greater 
Boston Food Bank, to raise awareness and funds during the 
holiday season for the 1 in 3 who are food insecure. We are 
proud to have matched up to $10,000 in employee donations 
in support of this cause.

School on Wheels
 — PureTech invited School on Wheels to come in and present 

during our monthly Town Hall to talk to us about their mission 
and goals. Following this, our employees assembled 144 
backpacks filled with supplies purchased by PureTech to 
donate to students impacted by homelessness. In addition to 
this, PureTech made a donation to LifeScience Cares, enabling 
employees to have priority access to volunteer opportunities 
there both in-person and virtual.

Promoting Employee Wellbeing
A shift to a hybrid working model has impacted work-life balance 
for many around the globe. At PureTech, we believe that 
wellbeing is critical to developing a sustainable and happy 
workplace. This includes ensuring physical, emotional, financial, 
social factors as well as a sense of community belonging, and 
purpose are prioritized. In 2023, we hosted onsite happy hours for 
all employees to wind down and connect with one another, and 
organized various initiatives and activities to promote 
employee wellbeing:

PureTech Coffee Chat Program
We continued to host our PureTech Coffee Chat Program to foster 
engagement, collaboration and connection amongst our peers. 
This optional program randomly paired participating employees 
across various departments to meet in-person or virtually to talk 
about their work and interests over coffee. 

Mental Health Awareness Program
In support of Mental Health Awareness month, resources and 
discounts for wellness programs, such as expert resources and 
virtual wellness classes, were introduced to all employees. 
Additionally, we hosted Krista Quinn, a wellness trainer and 
somatic therapy coach, to provide a guided meditation session 
to help employees unwind.

Employee Retreat
 — In 2023 we organized a companywide offsite retreat, 
welcoming all employees and their families to come 
together and join in on the fun. Team bonding exercises and 
workshops included encouraging individuals to come up 
with words and ideas they associate with PureTech’s 5 key 
values: Excellence in Everything We Do, Respect for People, 
Entrepreneurial and Scrappy, Dance to Our Own Tune, Trust 
and Integrity. The resulting word cloud reflecting employees’ 
perceptions perfectly encapsulated our company culture – 
a clear testament to the unity amongst team members and 
alignment of values.

PLANET

The deep interconnection between planetary and human health continues to reveal itself through trends like shifting disease vectors, 
extreme weather events, changing pollen patterns, and disrupted access to clean air and water. As we emerge from the COVID-19 
pandemic, we have an increased understanding of how environmental factors directly impact public health outcomes. At PureTech, we 
recognize our responsibility to account for and mitigate the detrimental effects our operations may have on communities already 
burdened by issues like pollution, biodiversity loss, water scarcity, and the mounting health consequences of climate change. By 
comprehensively analyzing our environmental footprint, we aim to benefit both people and planet.

While our impacts on the environment are limited as a result of the current scale of our operations and phase of our business, we 
remain committed to monitoring and reducing the environmental footprint that results from our operations. This means continuing to 
be aware of biodiversity and natural capital impacts and keeping up to speed with the latest regulations and reporting requirements. 
In addition, we are taking action by addressing the following key areas:

Commitment #1: 

Transparent GHG 
emissions disclosures

Commitment #3: 

Sustainable facility 
operations 

Commitment #2: 

Strengthen our waste 
management process

Our ESG framework continuedESG reportPureTech Health plc   Annual Report and Accounts 2023    41  

Commitment #1: 
Transparent GHG emissions disclosures

All carbon dioxide emissions and energy consumption figures 
relate to global operations. PureTech Health PLC is listed on the 
London Stock Exchange but operates in the United States of 
America. Therefore, emissions and energy consumption figures 
in this report relate to emissions in offshore areas.

The impact of climate change threatens the stability of the world 
and directly impacts human health. We understand it is the 
responsibility of everyone including businesses to mobilize and 
fight the worst impacts and keep the world aligned with 
1.5 degrees. As a clinical-stage biotherapeutics company with no 
approved therapeutics on the market, our current day-to-day 
impact on the environment is limited.

With that said, we are increasing the level of reporting and 
transparency around ESG as we build a stronger and more 
sustainable organization and will introduce climate-related 
targets, such as a net zero commitment and a transition plan to 
1.5ºC pathway when the state of operations is sufficiently 
advanced, such as entering a commercial stage, to render such 
analysis meaningful. At this stage, we believe that our operations 
have minimal environmental impact (see pages 54 to 58 for details 
of our TCFD report) to develop a robust climate-related target.

Streamlined Energy & Carbon Reporting
The section below, prepared by Verco, includes our fourth year of 
reporting under the Streamlined Energy & Carbon Reporting 
(SECR’) requirements. Verco is a leading sustainability and carbon 
consultancy with a 30-year track record supporting its clients to 
understand policy risks and delivering compliance services. 
Verco draws upon its considerable expertise and experience to 
ensure that the requirements of the SECR regulation are met.

The reporting period is the same as the Company’s financial year, 
January 1, 2023, to December 31, 2023.

Organization Boundary and Scope of Emissions
We have reported on all the emission sources required under the 
Companies Act 2006 (Strategic Report and Directors’ Reports) 
Regulations 2018 (‘Regulations’). These sources fall within the 
Company’s consolidated financial statement.

An operational control approach has been used in order to define 
our organizational boundary. This is the basis for determining the 
Scope 1, 2 and 3 emissions for which the Company is responsible.

The emissions sources that constitute our boundary for the year 
ending December 31, 2023, are:

 — Scope 1: Natural gas combustion;
 — Scope 2: Purchased electricity for our own use; and
 — Scope 3: Fuel used in personal/hire cars for business use, 
business travel, waste, water, well-to-tank emissions, and 
T&D emissions associated with electricity consumption. 
Please note that Scope 3, aside from fuel used in personal/
hire cars, is voluntary disclosure going beyond the 
Regulation requirements.

Methodology
We employed the services of a specialist adviser, Verco, to 
quantify and verify the Greenhouse Gas (GHG) emissions 
associated with our operations.

The following methodology was applied by Verco in the 
preparation and presentation of this data:

 — Principles of the Greenhouse Gas Protocol published by the 

World Business Council for Sustainable Development and the 
World Resources Institute (the “GHG Protocol”);

 — Application of appropriate emission factors, including DEFRA 
(2022) and eGRID (2021), to the our activity data to calculate 
GHG emissions;

 — For Scope 2 reporting, the application of appropriate 

emission factors to electricity consumption data to calculate 
location-based and market-based GHG emissions;

 — Presentation of gross emissions; no net figures are provided 

as the Company does not purchase carbon credits 
(or equivalents);

 — Inclusion of all applicable Kyoto gases, expressed in carbon 

dioxide equivalents, or CO2e;

 — Presentation of annual energy use, expressed in 

kilowatt-hours, or kWh;

 — The following assumptions have been used due to data not 
being obtainable or unable to be confirmed by the time 
of this report: 
 – As supplier-specific generation mix information was 

unavailable, the United States Environmental Protection 
Agency (‘EPA’) and the Department for Environment, Food 
& Rural Affairs (‘DEFRA’) residual fuel mix emissions factors 
have been used to calculate market-based emissions.

 – 136 Harrison Avenue did not have electricity consumption 
data available. Verco estimated the figure by applying 
Real Estate Environmental Benchmarks (‘REEB’) and 
Building Energy Efficiency Survey (‘BEES’) benchmarks to 
the floor area.

 – PureTech Health PLC have provided the total mileage 

claimed by employees for business travel in personal cars 
across the reporting period. Verco have used a relevant 
emissions factor, for an average car size, to calculate the 
associated emissions. 

 – PureTech Health PLC have provided the total mileage of 

flights taken by employees for business travel throughout 
the reporting period. Verco have used a relevant 
emissions factor, for domestic US flights, to calculate the 
associated emissions.

Note: Consistent with the Company’s consolidated financial statement, the emissions report leading up to FY2022 included our 
controlled Founded Entity, Vedanta, data. An increase in energy use for FY2022 was largely driven by the energy consumption at the 
Vedanta facility. Vedanta has been deconsolidated as of FY2023. 

Intensity Ratio
As well as reporting the absolute emissions, intensity ratios for the Company’s emissions have been provided below. The Company’s 
GHG emissions intensity is expressed as tonnes of  CO2 equivalent per m2 of floor area and per number of full-time employee (FTE).

These were selected as the most appropriate metrics for the Company, as the majority of emissions result from the operation of the 
Company’s premises and employee travel. These metrics are also consistent with previous years.

The intensity ratios are as follows:

 — 0.03 t CO2e per m2 of total floor area and 1.87 t CO2e per FTE (location-based method).
 — 0.03 t CO2e per m2 of total floor area 1.87 t CO2e per FTE (market-based method).

The intensity ratios for FY2023 have been calculated using a total floor area of 5,018 m2 and total number of 90 full-time employees.

Our ESG framework continuedESG reportPureTech Health plc   Annual Report and Accounts 2023    43  

Baselines and Progress
The Company’s absolute GHG emissions have seen a decrease of approximately 21.9 t CO2e, when using both the location-based and 
market-based method for Scope 2 emissions. This can be attributed to a reduction in electricity and gas consumption, as a result of the 
termination of the Company’s lease for one of its sites in March 2023. On the other hand, Scope 3 emissions have increased by 27% 
compared to FY2022, due to a surge in business travel, particularly flights. The emissions categories  CO2/dry ice and third-party 
deliveries, which were reported on in FY2022, are not included in FY2023 reporting.

Understanding the Indirect Environmental Impacts of our Business Activities
While our direct environmental footprint as a clinical-stage biotherapeutics company is relatively modest, PureTech recognizes the 
broader influence we can have through our strategic investment decisions. Guided by our comprehensive Environmental, Social and 
Governance (ESG) framework, we consider environmental and social impacts when assessing potential partner companies, in addition 
to governance and ethical practices. 

We prioritize business partners that demonstrate accountability through ambitious goals, transparent reporting and full compliance 
with all applicable regulations related to emissions to waste, energy usage to diversity, equity and inclusion.

While our own operations may have minimal ecological impact directly, the companies we choose to fund create ripples across 
industries and communities worldwide. By selecting partners based on ESG initiatives, we amplify our positive influence. Our 
investment decisions shape a rising tide that lifts environmental stewardship, social progress and ethical business practices.

At PureTech, we are committed to reducing our operational waste, recycling and reusing where possible and ensuring the safe disposal 
of hazardous material. We partner with Veolia Environment and Triumvirate for the management of our hazardous medical waste. 
Veolia’s Voluntary Protection Programs (‘VPP’) are rated by OSHA and all staff are HAZWOPER certified. Triumvirate is a sustainable 
environmental solutions provider helping organizations reduce waste, stay safe and compliant, and manage risk. In 2023, PureTech 
produced 1,174lbs (98kg) of biologically and chemically hazardous waste in the course of its research. The majority of this waste is 
disposed of through incineration or for fuels blending. Full details of waste generated and treatment methods are shown in the 
tables below.

The decrease in waste volume was driven by the closure of our lab space due to the scale-back of our R&D operations in 2023, which 
also drove the increase in fuel blending and incineration due to hazardous material disposal. 

PureTech will continue to monitor these output levels as part of a commitment to keep hazardous waste to a minimum.

Commitment #3: 
PureTech’s Energy-Efficient Headquarters

PureTech’s headquarters at Innovation Square, 6 Tide Street in Boston, is a bro wnfield redevelopment site offering many 
environmental benefits.

Innovation Square consolidates PureTech’s laboratory and business operation functions in one building, reducing the need for 
employees to commute between multiple locations.

The building is in close proximity to public transportation and is equipped with ample bicycle storage – twice the amount required by 
LEED for the building’s size – to encourage green commuting. The building also has on-site shower and changing facilities for cleanliness 
and hygiene.

Drivers of electric vehicles (EVs) have access to four charging points in the parking area. Employees are also encouraged to take public 
transportation to work via a travel subsidy, while an office shuttle bus runs to and from the major Boston train stations.

The building is certified LEED Silver. The fit-out incorporates a range of elements to encourage efficient resource use including:18

 — A roof featuring reflective materials to reduce the building’s heat island effect.
 — Water use reduction of up to 39% through features such as low-flow toilets.
 — Water-efficient landscaping using hardy and drought tolerant plants to reduce irrigation by 50% over a midsummer baseline case.
 — Design and model expected to use 35% less energy than the LEED baseline across heating, cooling, lighting, hot water production 

and other operational functions.

 — Designed to generate 47% fewer greenhouse gas (GHG) emissions than the AIA 2030 Challenge baseline, equivalent to an annual 

reduction of 2,500 metric tonnes of CO2e.

 — Use of low-emitting flooring, paints and sealants in the construction in compliance with the US SCAQMD Rule #1168 to reduce 

VOC emissions.

 — No chlorofluoro-carbon-based refrigerants (CFCs) were used in building heating, ventilation, air conditioning and 

refrigeration systems.

 — PureTech’s kitchen area is stocked with reusable utensils, plates, cups and glasses to minimize the use of disposable items. 

Every conference room has recycling bins for paper and other waste, as do all kitchens.

18  All data in this section is taken from the Article 37 Green Building Report and LEED checklist developed by WSP for the building’s landlords, Related Beal.

GOVERNANCE

Our work would not be possible without trust – it is a core value on which our success depends, and the foundation of our relationship 
with our stakeholders. We prioritize meeting our stakeholders’ expectations by being responsible corporate citizens and holding 
ourselves to the highest ethical standards of compliance and transparency. Our approach to Governance, which underpins our focus 
on Patients, People and Planet, centers on the following key areas:

Commitment #1: 

Establish and maintain  
a strong ESG governance

Commitment #3: 

Strengthen supply  
chain standards 

Commitment #2: 

Uphold high standard 
business ethics

PureTech’s governance framework is described in detail in pages 
59 to 122 of this report in line with the UK Corporate 
Governance Code.

ESG Governance
PureTech recognizes the importance of good governance in 
delivering positive ESG outcomes, in line with the long-term 
objectives of the business. The Board maintains direct oversight 
and is ultimately responsible for our performance. Our ESG 
strategy is driven by the ESG Committee, which reports directly 
to the Board, and guides our approach and provides the 
important framework to deliver on this strategy in 
a consistent manner. 

Our ESG Committee was founded in 2020 and is chaired by 
non-Executive Director, Kiran Mazumdar-Shaw. The ESG 
committee is responsible for managing, reviewing and advancing 
our ESG progress and enhancing disclosure and transparency 
through our annual ESG reporting process. While not part of the 
Board of Directors, the ESG Committee, along with other Board 
Committees, meets with the Board on a quarterly basis (or as the 
need arises) to assess and monitor ESG risks and provide updates 
on progress regarding the implementation of strategy.

The ESG committee is composed of a non-Executive Director 
and supported by at least one C-Suite Officer, and reports 
directly to the Board. The work of the ESG Committee is 
supported by a dedicated internal working group, that is 
responsible for the implementation of strategy and welcomes 
active engagement with shareholders and other stakeholders on 
matters relating to ESG and corporate stewardship.

Our TCFD Report, on pages 54 to 58, provides additional detail on 
the role and responsibilities of the Board and our Management 
Team in the oversight and implementation of our ESG strategy.

Commitment #2: 
Uphold high standard business ethics

Sustainability-linked remuneration
As of 2023, we have not set any climate-related targets or 
incorporated such targets into our remuneration policies. While 
we are cognizant of the ESG preference at large to incorporate 
sustainability-related metrics into companies’ executive 
remuneration policies, we believe it is most beneficial for our 
stakeholders when the remuneration metrics are material to the 
business, suitably stretching and clearly linked to the strategy of 
the business. Given the size and nature of our business, we do not 
yet deem it appropriate or material to set far-reaching ambitions 
in this area.

19  Board composition as of December 31, 2023.
20 Board composition as of December 31, 2023.

Board Diversity
The Board and Management continue to recognize the benefits 
of diversity and the requirements set out in the FCA Diversity 
Policy, as well as the expectations set out in the FTSE Women’s 
Leaders Review and the Parker Review. Reflective of this 
commitment was our recognition as one of the leading 
organizations for Board diversity across the FTSE 250. We take 
great pride in the diversity of our leadership team, which at the 
end of 2023, PureTech Board and Executive Committee 
accounted for:

 — 43% gender diversity at Board level19
 — 57% cultural diversity at Board level20

Our commitment to championing diversity of gender and 
ethnicity in particular has been longstanding. While the Parker 
Review called for the appointment of at least one non-Executive 
Director from an ethnic minority background by 2021 – “One by 
2021” – we had already achieved this target in 2019. We are 1 of 
only 8 FTSE250 companies to have met and exceeded the 2024 
target with a minority ethnic Chair and more than two minority 
ethnic directors in the business, and 1 of only 14 FTSE250 
companies with a minority ethnic CEO. The Board is cognizant of 
the updated targets set by the Parker Review for the appointment 
of an Executive Director from an ethnic minority background by 
December 2027. The current composition of our Executive team 
positions us to be in alignment with these expectations, and we 
will continue to take all aspects of diversity into consideration as 
part of our ongoing Board and Executive Management 
refreshment.

In 2021, we met FTSE Women Leaders Review’s increased gender 
diversity target recommending FTSE 350 companies to achieve 
a minimum of 40% women on Boards and in Leadership teams by 
the end of 2025, and we continued to uphold this high 
standard in 2023.

For details on our gender diversity initiatives, please see page 35.

Our detailed Board and Executive Management diversity data is 
set out in page 53 of this report as required by the Listing Rules LR 
9.8.6(10) Annex 2.1. Data is for the PureTech Board and Executive 
Management as of December 31st, 2023. Numbers in this table 
are based on how individuals identify themselves.

Business Ethics
For PureTech, being an ethical business means operating with 
transparency to ensure just and inclusive behaviors throughout 
our organization and across our day-to-day interactions.

We are committed to acting with transparency, integrity, 
professionalism and excellence to uphold deep levels of trust 
with our stakeholders. This requires careful observance of all 
applicable laws and regulations, as well as regard for the highest 
standards of conduct and personal integrity.

Anti-Bribery and Corruption
PureTech has written policies and reporting procedures in place 
on its zero-tolerance approach to bribery and corruption that 
have been reviewed and approved by the Board of Directors. 
These policies are detailed in our Code of Business Conduct and 
Ethics, and our Anti- Bribery Policy outlines the expectations we 
have for all employees when it comes to anti-bribery 
and corruption.

We take a zero-tolerance approach to bribery and corruption in 
all its forms. Specific principles related to anti-bribery and 
corruption are outlined in our Professional Practices Policy, while 
third-party risk is governed by our Anti-Bribery Third- Party 
Guidelines. PureTech is bound by UK laws, including the Bribery 
Act 2010, and has implemented policies and procedures 
accordingly.

Employees are required to review and consent to PureTech’s 
corruption, anti-trust violations, and conflicts of interest policy 
during the onboarding process and reinstate their commitment 
on an annual basis.

The terms of our Whistleblowing Policy have been formally set 
out in the Employee Handbook and published on our intranet. To 
prevent bribery and corruption, our Whistleblowing Policy 
encourages our staff to confidentially report any ethical concerns, 
wrongdoings, breaches, or improper conduct by or on behalf of 
the Company without fear of reprisal. This includes an external 
hotline to allow employees to report suspected issues, 
allegations and concerns anonymously. Appropriate individuals, 
depending on the nature of the specific issue at hand, investigate 
all allegations of misconduct and communicate findings to the 
proper personnel inside the Company, which often includes the 
CEO, to ensure that all concerns are addressed. The results of 
these investigations are reported to the Audit Committee.

The Audit Committee is satisfied that the Policy has been 
designed in a manner that encourages staff to report suspected 
wrongdoing as soon as possible and provides guidance on how 
to raise any concerns. In 2023, PureTech was not involved in and 
suffered no monetary losses due to legal proceedings related to 
corruption and bribery.

Code of Ethics for HealthCare Professionals
PureTech maintains a policy to ensure that interactions and 
business relationships with healthcare professionals (HCPs) are 
conducted in accordance with applicable regulations and ethical 
standards. The policy states, among other things, that (a) HCPs 
will be selected solely on the basis of their qualifications and (b) 
payments will be made at fair market value taking into account 
purchasing history or volume or prospective ability to drive sales. 
The policy provides the roadmap for engagement of HCPs and 
regulates interactions between PureTech and HCPs.

Anti-Harassment and Grievance Mechanism
 PureTech is committed to providing a work environment that is 
free of harassment based on sex, race or any other personal 
characteristic protected under federal or state law. PureTech 
does not tolerate any forms of harassment or offensive conduct, 
including sexual harassment or any other form of harassment, as 
is clearly outlined in our Harassment Policy. The policy states our 
position towards any behavior that impacts an individual’s 
self-esteem at work and provides examples of 
prohibited behavior.

All PureTech employees are required to complete mandatory 
annual anti-harassment training to ensure that all employees are 
able to recognize and identify behaviors that may cause harm to 
their colleagues.

The training highlights the importance of creating an environment 
that encourages respect for all people and also provides an 
overview of our grievance reporting structure and how 
inappropriate conduct is handled. To ensure continuous 
compliance and awareness, we send periodic reminders to 
encourage our employees to undertake refresher training relating 
to anti-corruption. We also ensure that all new employees 
complete training during onboarding.

PureTech is committed to maintaining its reputation for honesty, 
fairness, respect, responsibility, integrity, trust and sound 
business judgment. As part of this commitment to ethical and 
legal conduct, we strongly encourage all employees to ask 
questions and report any concerns.

PureTech’s Compliance HelpLine allows employees to report 
suspected issues, allegations and concerns anonymously either 
through our internal or external helplines. It is a violation of 
PureTech’s policy to retaliate against anyone raising a question or 
reporting a good faith concern.

Human Rights and Modern Slavery
We are committed to being a responsible corporate citizen by 
supporting the protection and advancement of human rights for 
our people, patients and the communities in which we operate. 
We fully support the Children’s Rights and Business Principles set 
out by the UN Declaration of the Rights of the Child and 
their protection.

In light of the size of our business and the nature of our business, 
PureTech is exempt from producing a Modern Slavery statement. 
However, we do not have cause to believe that any breaches in 
Modern Slavery are occurring within our business or supply chain, 
and we are striving to adopt a Modern Slavery transparency 
statement in the future.

In 2023, we made progress towards establishing and 
implementing a Business Continuity Plan (BCP) to provide for 
recovery of critical business functions in case of any unplanned 
events. As we prepare our BCP, and to ensure that we have 
identified any potential weaknesses in our process, an external 
vulnerability and verification analysis was carried out by an 
external third-party which allows us to identify and improve any 
potential weaknesses in our processes. We will continue to 
evaluate and prioritize risks and uncertainties that may impact our 
operation and will implement formal BCP in due course.

Some of the tools currently in place to enhance our cyber security 
include, but are not limited to:

 —  VulScan: Identifies security vulnerabilities in our network to 
ensure business continuity. The tool provides up-to-date 
information on the degrees of risk for each vulnerability and 
provides appropriate mitigation strategies.

 —  Crowdstrike: Used for endpoint protection and to secure the 

most critical areas of enterprise risk.

We believe a robust IT infrastructure and the development of 
a BCP are essential to secure and improve the resilience of the 
business. In light of the accelerated digital transformation and 
associated security risks that the pandemic and geopolitical 
issues have brought about in recent years, cybersecurity remains 
a key area of focus of our leadership. Given its material risks to the 
business, it also represents a key component of our BCP. 

Data Privacy and Security
PureTech is committed to upholding and protecting the privacy 
of our business members and our stakeholders. Our Information 
Security Acceptable Use Policy outlines the acceptable use of 
computer equipment, systems, and software at PureTech, and 
maintains a balance between our established culture of 
openness, trust and integrity whilst ensuring the safety and 
security of our stakeholders, systems, and information.

All employees are required to complete an annual cybersecurity 
training to increase employees’ awareness and understanding of 
cybersecurity risk.

Additionally, to ensure all clinical trial participant privacy and 
confidentiality of Protected Health Information (PHI) are 
protected during the conduct of a clinical trial sponsored by 
PureTech, all employees who are involved in our clinical trial 
operations are required to follow our PHI Standard Operating 
Procedure (SOP). (See pages 32 to 33 for more on patient safety).

Supply Chain
Given the nature of our business operations as a clinical- stage 
company, we have a small-scale supply chain, which is mainly 
comprised of material suppliers for the development of our 
Internal Programs. As a result, our environmental and social 
impacts are minimal at the current scale and phase of our 
business. Nevertheless, we are committed to ensuring that all 
aspects of our business operations, including relationships with 
our suppliers, are sustainable, ethical and responsible.

Our Commitment to ESG
PureTech takes pride in its commitment to the community that it 
consists of (its people), the community it serves (its patients) and 
the community that it participates within (the world at large). Our 
team is dedicated to furthering our mission of changing the lives 
of patients with devastating diseases, and we are aware that this 
can only be achieved through a sustainable business.

We believe that our environmental, social, and governance 
initiatives are crucial to achieving our goals, and we are 
committed to making continuous advancements across 
these areas.

By reporting our ESG metrics, we can better track our progress 
and identify areas for improvement, helping us to further direct 
PureTech towards a brighter future.

To achieve this, we have a robust Quality Management System 
(QMS) in place to oversee our material suppliers. This consists of 
several key SOPs which describe the controlled processes we 
follow regarding qualification, evaluation, change management, 
and training, to name a few areas, and ensure consistent 
conformance to our high standards. More details on our SOPs are 
included in the Patients Section of this Report under Ethical R&D 
(see pages 32 to 33).

Stakeholder Stewardship
PureTech remains committed to being a good corporate citizen 
and our ESG program is one way of delivering on this 
commitment. Our stakeholders’ feedback is vital to us in order to 
improve our sustainability performance and disclosure. 
Accordingly, we welcome your comments, questions, or 
suggestions on how we can enhance our ESG efforts in the future 
by emailing us at: esg@puretechhealth.com.

To determine vendor risks and accelerate new vendor 
onboarding, risk assessment processes are built into all our 
procedures for vendor audits and data integrity for Chemistry, 
Manufacturing, and Controls (CMC). In 2023, ~30% of our Tier I 
suppliers who provide materials for our clinical development 
participate in Rx-360 International Pharmaceutical Supply Chain 
Consortium equivalent audit programs.

Appendix
PureTech continues to utilize the Sustainability Accounting 
Standards Board (SASB) sector guidance for our ESG disclosures 
this year. At the same time, we are monitoring the International 
Sustainability Standards Board (ISSB) as it works to establish 
a global baseline for sustainability reporting standards. 
We anticipate incorporating the ISSB standards into our ESG 
reporting process once they are finalized and implemented 
across our sector.

TCFD REPORT

Overview
In this section, we present PureTech’s third formal climate related 
financial disclosures that are partially consistent with all four 
themes and eleven recommended disclosures from Section C of 
the Annex entitled ‘Implementing the Recommendations of the 
Task Force on Climate-related Financial Disclosures’, published in 
October 2021 by the TCFD, outlining PureTech’s continued 
efforts to adopt, measure, manage and mitigate its climate and 
sustainability-related impacts. We believe that our ability to 
manage any potential climate-related impacts on our business 
and strategic direction is integral to our success. 

As a clinical-stage biotherapeutics company, we operate in an 
inherently high-risk environment. The overall aim of our risk 
management effort is to achieve an effective balancing of risk 
and reward. Risks are formally identified by the Board and 
appropriate processes are put in place to monitor and mitigate 
them on an ongoing basis (see details on risk management on 
pages 60 to 64 of the 2023 Annual Report and Accounts). Due to 
the size, scale and nature of our operations (see “Strategy”), we 
have concluded that PureTech is unlikely to face any material 
climate-related physical or transition risks in the short to medium-
term. Materiality is defined by whether an event will have an 
adverse effect on to PureTech’s financial condition, development, 

or results of operations. Where appropriate, we use short-, 
medium- and long-term horizons to assess the climate related 
impact to our operation. For short-term time horizon we use 2-4 
years, for medium-term time horizon 5-6 years, and for long-term 
time horizon over 7 years.

While our impact on the environment is minimal, we are 
committed to mitigating climate-related risks in line with 
emerging climate science as our business continues to expand. 
To achieve this, we focus on managing energy consumption 
across our operations, optimizing employee commuting, and 
managing third-party deliveries.

We also measure our ESG-related performance and have 
embedded effective procedures and processes within our risk 
management framework. Our risk management metrics are set 
forth on pages 60 to 64 of our 2023 Annual Report and Accounts 
and are reviewed by the Executive team and the Board to ensure 
we are taking appropriate action.

Our process and the actions outlined below refer to PureTech’s 
approach as of December 31, 2023.

Our ESG framework continuedESG report 
PureTech Health plc   Annual Report and Accounts 2023    55  

Governance
Our Board of Directors is tasked with risk identification and with 
implementing procedures and strategies for risk mitigation and 
management, including climate-related risks. This is discussed 
during periodic meetings to identify any key or emerging risks 
facing PureTech.

The Board utilizes its risk management framework to guide our 
overall strategy, business planning, corporate policies, actions, 
and objectives. These are implemented by our management 
team with oversight and advice from the Board. This process 
includes monitoring any emerging or ongoing climate or 
environmental-related risks. More information on the roles and 
responsibilities of the Board, including detail on our risk 
management framework can be found on pages 86 to 90 of our 
2023 Annual Report and Accounts.

PureTech’s ESG Committee is chaired by Non-Executive Director 
Kiran Mazumdar-Shaw with the responsibility to effectively 
manage, review and advance ESG issues on an ongoing basis. 
Ms. Mazumdar-Shaw is an avid climate advocate and leads ESG 
initiatives across the companies she serves. PureTech’s ESG 
Committee process includes assessing and overseeing 
PureTech’s climate-related risks and opportunities, as well as 
considering how these should inform business planning and 
strategic focus into the future. The ESG committee considers 
climate-related risks on at least an annual basis or more often 
as the need arises. All findings are reported to the Board.

As of 2023, the ESG Committee composed of a non-Executive 
Director and supported by at least one C-Suite Officer, and 
a dedicated internal working group of cross-functional leaders to 
drive internal action and implementation, reporting directly to 
the Board. The ESG Committee is supported by several third-
party experts to guide our approach. The Committee 
periodically reports its activities to the Board during scheduled 
meetings or via updates throughout the year. The progress of our 
ESG initiatives is reported in our 2023 Annual Report and 
Accounts, see pages 22 to 50 for more.

Strategy
To identify physical and transitional climate-related risks and 
opportunities that may impact our business, PureTech conducts 
detailed analysis with third-party organizations, including an ESG 
expert, to guide our strategic approach.

This analysis has led us to conclude that PureTech is unlikely to 
face any material climate-related risk and opportunities in the 
short, medium to long term, particularly due to the scope and 
scale of our operations. Looking ahead, we will continue to 
conduct broad-based risk assessments and monitor the following 
climate-related risks and opportunities and their potential 
financial impacts identified through our risk management on an 
ongoing basis (for their short, medium and long-term risk):

 — Transitional and Market risks: Associated with higher 

operating costs due to the introduction of carbon pricing/
taxation schemes or other supply-chain cost increases
 — Physical and Market risks: Associated with supply chain or 
operational disruption leading to increased costs from the 
increased severity of extreme weather events, or long-term 
changes to weather patterns

 — Transitional and Reputational risks: Associated with any 
potential impacts to reputation if PureTech falls short 
of stakeholder expectations regarding climate-related 
performance or impact management

 — Transitional and Legal and Reputational risks: Associated 

with the increased cost of compliance/non-compliance with 
new climate regulations and reporting

 — Market opportunities: Associated with reducing operating 

costs through energy-efficient improvements

 — Transitional and Reputational opportunities: Associated with 
being early-adopters of enhanced disclosure measures or 
low-carbon technologies

As we continue our operation as a good corporate citizen, we 
have taken steps to improve upon the managing risks, should 
they arise. For example, we have initiated compiling a Business 
Continuity Plan (BCP) in 2023 to ensure that our physical 
operations and supply chains have effective measures in place to 
mitigate any potential climate-related risks. As part of the 
transitional planning, we intend to have a formal BCP in place in 
the short-term horizon (see page 49 of the 2023 Annual Report 
and Accounts for more information on our BCP). For further 
information on the Company’s risk assessment, monitoring and 
mitigation efforts, please see Risk Management section of the 
2023 Annual Report and Accounts (see pages 60 to 66).

Risk Management
While climate-related risks are not currently identified as 
a principal risk for PureTech, we will continue to monitor our 
climate-related risk profile as internal and external 
circumstances change.

Risks are formally identified by the Board and appropriate 
processes are in place to monitor and mitigate them on an 
ongoing basis (see “Governance”). On an annual basis, our 
auditors perform a risk assessment to consider the potential 
impacts of climate change on our business, financial statements 
and the audit. This included making enquiries of management to 
understand the extent of the potential material impact of climate 
change risk on our financial statements (see page 125 of the 2023 
Annual Report and Accounts for more). In addition, we are 
committed to introducing climate risk tools and processes that 
identify, manage and act on any material climate-related risks 
should the needs arise. Our ESG committee, with the counsel of 
third-party ESG experts, considers climate-related risks and 
strategic priorities on an annual basis, or more regularly, as the 
need arises.

As part of our climate-related monitoring program, PureTech 
employs external consultants to audit and report on our climate-
related metrics, including the following assessments which are 
more fully discussed in our 2023 ESG Report on pages 22 to 50:

 — Streamlined Energy and Carbon Reporting (SECR) 

prepared by Verco

 — Green Building Report and LEED Checklist prepared by 
WSP in conjunction with Related Beal, the landlord of our 
headquarters facility

 — Hazardous Waste Reporting prepared by Veolia Environment 

S.A. and Triumvirate Environmental

These findings inform the ESG Committee’s climate risk analysis 
strategy to identify and act on any physical and transition risks 
considered material to the Company.

Metrics and Targets
PureTech employs the services of a B Corp certified specialist 
adviser Verco, to quantify and verify the GHG emissions 
associated with its operations. We report our Scope 1 and 2 
emissions as required under the Companies Act 2006 
(Strategic Report and Directors’ Reports) Regulations 2018 and 
the Streamlined Energy and Carbon Reporting (SECR) guidelines. 
We also voluntarily report our Scope 3 emissions categories that 
are relevant to our business.

An operational control approach is used to define our 
organizational boundary. This is the basis for 
determining emissions.

The emissions sources that constitute our boundary include:

 — Scope 1: natural gas combustion within boilers and carbon 

dioxide used in our laboratories;

 — Scope 2: purchased electricity for our own use; and
 — Scope 3: business travel, employee commuting, and third-
party deliveries. We do not report on all 15 categories 
of the GHG Protocol as not all categories are material to 
our operation. 

Our current emissions profile, as well as other environmental-
related measures adopted, can be found in our 2023 ESG Report 
(pages 44 to 45 of the 2023 Annual Report and Accounts). 
PureTech considers whether additional environmental metrics 
should be developed and reported on throughout the year.

Given (a) the nature of our industry, business operations and 
therapeutic mission and (b) we have not identified any material 
climate-related risks to our business, PureTech has not set any 
emissions-related targets to date. We do plan on introducing 
climate-related targets when our operations have sufficiently 
advanced beyond clinical stage and deem this necessary.

Next steps
We remain committed to operating as a good corporate citizen, 
and to managing the climate-related impacts of our operations 
and environmental matters. We intend to (1) enhance climate-
related risks and opportunities management, (2) identify and 
address areas of improvement year-on-year, and (3) set GHG 
emissions targets and measure performance and progress 
annually in the medium-term time horizon.

Risk management

The execution of the Group’s strategy is subject to a range of risks and uncertainties. As a clinical-stage biotherapeutics company, the 
Group operates in an inherently high-risk environment. The Group’s strategic approach seeks to aid the Group’s risk management 
efforts to achieve an effective balancing of risk and reward. Risk assessment, evaluation and mitigation are integral parts of the Group’s 
management process. The Group, however, also recognizes that ultimately no strategy provides an assurance against loss, as we 
saw in the current year with Gelesis, which ceased operations and filed a voluntary petition for Chapter 7 bankruptcy liquidation in 
October 2023.

Risks are formally identified by the Board and appropriate internal controls are put in place and tailored to the specific risks to monitor 
and mitigate them on an ongoing basis. If multiple or an emerging risk event occurs, it is possible that the overall effect of such events 
would compound the overall effect on the Group. The principal risks that the Board has identified as the key business risks facing the 
Group are set out in the table below along with the impact and mitigation management plan with respect to each risk. These risks are 
only a high-level summary of the principal risks affecting our business; any number of these or other risks could have a material adverse 
effect on the Group or its financial condition, development, results of operations, subsidiary companies and/or future prospects. 
Further information on the risks facing the Group can be found on pages 186 to 223 which also includes a description of circumstances 
under which principal and other risks and uncertainties might arise in the course of our business and their potential impact.

Management Plans/Actions

1   Risks related to science and 

technology failure 

The science and technology being developed or 
commercialized by some of our businesses may fail 
and/or our businesses may not be able to develop 
their intellectual property into commercially viable 
therapeutics or technologies.

There is also a risk that certain of the businesses 
may fail or not succeed as anticipated, resulting in 
significant decline of our value.

The failure of any of our 
businesses could decrease 
our value. A failure of one of 
the major businesses could 
also impact the reputation of 
PureTech as a developer of high 
value technologies and possibly 
make additional fundraising by 
PureTech or any Founded Entity 
more difficult or unavailable on 
acceptable terms at all.

Prior to additional steps in the development 
of any technology, extensive due diligence is 
carried out that covers all the major business risks, 
including technological feasibility, competition and 
technology advances, market size, strategy, adoption 
and intellectual property protection.

A capital efficient approach is employed, which 
requires the achievement of a level of proof of 
concept prior to the commitment of substantial 
capital is committed. Capital deployment is 
generally tranched to ensure the funding of 
programs only to their next value milestone. 
Members of our Board or our management team 
serve on the board of directors of several of the 
businesses so as to continue to guide each business’s 
strategy and to oversee proper execution thereof. 
We use our extensive network of advisors to ensure 
that each business has appropriate domain expertise 
as it develops and executes on its strategy and the 
R&D Committee of our Board reviews each program 
at each stage of development and advises our Board 
on further actions. Additionally, we have a diversified 
model with numerous assets such that the failure of 
any one of our businesses or therapeutic candidates 
would not result in a failure of all of our businesses.

2  Risks related to clinical trial failure 
Clinical trials and other tests to assess the 
commercial viability of a therapeutic candidate are 
typically expensive, complex and time-consuming, 
and have uncertain outcomes.

Conditions in which clinical trials are conducted 
differ, and results achieved in one set of conditions 
could be different from the results achieved in 
different conditions or with different subject 
populations. If our therapeutic candidates fail to 
achieve successful outcomes in their respective 
clinical trials, the therapeutics will not receive 
regulatory approval and in such event cannot be 
commercialized. In addition, if we fail to complete 
or experience delays in completing clinical tests 
for any of our therapeutic candidates, we may 
not be able to obtain regulatory approval or 
commercialize our therapeutic candidates on a 
timely basis, or at all.

3  Risks related to regulatory approval
The pharmaceutical industry is highly regulated. 
Regulatory authorities across the world enforce 
a range of laws and regulations governing the 
testing, approval, manufacturing, labelling and 
marketing of pharmaceutical therapeutics. 
Stringent standards are imposed which relate 
to the quality, safety and efficacy of these 
therapeutics. These requirements are a major 
determinant of the commercial viability of 
developing a drug substance or medical device 
given the time, expertise and expense which must 
be invested. 

We may not obtain regulatory approval for our 
therapeutic candidates. Moreover, approval in 
one territory offers no guarantee that regulatory 
approval will be obtained in any other territory. 
Even if therapeutics are approved, subsequent 
regulatory difficulties may arise, or the conditions 
relating to the approval may be more onerous or 
restrictive than we anticipate.

A critical failure of a clinical trial 
may result in termination of 
the program and a significant 
decrease in our value. Significant 
delays in a clinical trial to support 
the appropriate regulatory 
approvals could impact the 
amount of capital required for 
the business to become fully 
sustainable on a cash flow basis.

We have a diversified model to limit the impact 
of clinical trial outcomes on our ability to operate 
as a going concern. We have dedicated internal 
resources to establish and monitor each of the clinical 
programs for the purpose of maximising successful 
outcomes. We also engage outside experts to help 
create well-designed clinical programs that provide 
valuable information and mitigate the risk of failure. 
Significant scientific due diligence and preclinical 
experiments are conducted prior to a clinical trial 
to evaluate the odds of the success of the trial. In 
the event of the outsourcing of these trials, care 
and attention are given to assure the quality of the 
vendors used to perform the work.

The failure of one of our 
therapeutics to obtain any 
required regulatory approval, or 
conditions imposed in connection 
with any such approval, may 
result in a significant decrease 
in our value.

We manage our regulatory risk by employing highly 
experienced clinical managers and regulatory 
affairs professionals who, where appropriate, will 
commission advice from external advisors and 
consult with the regulatory authorities on the design 
of our preclinical and clinical programs. These 
experts ensure that high-quality protocols and other 
documentation are submitted during the regulatory 
process, and that well-reputed contract research 
organizations with global capabilities are retained 
to manage the trials. We also engage with experts, 
including on our R&D Committee, to help design 
clinical trials to help provide valuable information 
and maximize the likelihood of regulatory approval. 
Additionally, we have a diversified model with 
numerous assets such that the failure to receive 
regulatory approval or subsequent regulatory 
difficulties with respect to any one therapeutic 
would not adversely impact all of our therapeutics 
and businesses.

Management Plans/Actions

Adverse reactions or 
unacceptable side effects 
may result in a smaller market 
for our therapeutics, or even 
cause the therapeutics to fail to 
meet regulatory requirements 
necessary for sale of the 
therapeutic. This, as well as any 
claims for injury or harm resulting 
from our therapeutics, may 
result in a significant decrease in 
our value.

Safety is our top priority in the design of our 
therapeutics. We conduct extensive preclinical and 
clinical trials which test for and identify any adverse 
side effects. Despite these steps and precautions, we 
cannot fully avoid the possibility of unforeseen side 
effects. To mitigate the risk further we have insurance 
in place to cover product liability claims which may 
arise during the conduct of clinical trials.

The failure to obtain 
reimbursement from third 
party payers, and competition 
from other therapeutics, could 
significantly decrease the amount 
of revenue we may receive from 
therapeutic sales for certain 
therapeutics. This may result in a 
significant decrease in our value.

We engage reimbursement experts to conduct 
pricing and reimbursement studies for our 
therapeutics to ensure that a viable path to 
reimbursement, or direct user payment, is available. 
We also closely monitor the competitive landscape 
for our therapeutics and therapeutic candidates 
and adapt our business plans accordingly. Not 
all therapeutics that we are developing will rely 
on reimbursement. Also, while we cannot control 
outcomes, we seek to design studies to generate 
data that will help support potential reimbursement.

4  Risks related to therapeutic safety
There is a risk of adverse reactions with all drugs 
and medical devices. If any of our therapeutics are 
found to cause adverse reactions or unacceptable 
side effects, then therapeutic development may 
be delayed, additional expenses may be incurred 
if further studies are required, and, in extreme 
circumstances, it may prove necessary to suspend 
or terminate development. This may occur even 
after regulatory approval has been obtained, 
in which case additional trials may be required, 
the approval may be suspended or withdrawn 
or require product labels to include additional 
safety warnings. Adverse events or unforeseen 
side effects may also potentially lead to product 
liability claims against us as the developer of the 
therapeutics and sponsor of the relevant clinical 
trials. These risks are also applicable to our 
Founded Entities and any trials they conduct or 
therapeutic candidates they develop.

5   Risks related to therapeutic profitability 

and competition

We may be unable to sell our therapeutics 
profitably if reimbursement from third-party 
payers – such as private health insurers and 
government health authorities – is restricted or not 
available. If, for example, it proves difficult to build 
a sufficiently strong economic case based on the 
burden of illness and population impact.

Third-party payers are increasingly attempting to 
curtail healthcare costs by challenging the prices 
that are charged for pharmaceutical therapeutics 
and denying or limiting coverage and the level of 
reimbursement. Moreover, even if the therapeutics 
can be sold profitably, they may not be adopted by 
patients and the medical community.

Alternatively, our competitors – many of whom 
have considerably greater financial and human 
resources – may develop safer or more effective 
therapeutics or be able to compete more 
effectively in the markets targeted by us. New 
companies may enter these markets and novel 
therapeutics and technologies may become 
available which are more commercially successful 
than those being developed by us. These risks are 
also applicable to our Founded Entities and could 
result in a decrease in their value.

6   Risks related to intellectual property 

protection

We may not be able to obtain patent protection 
for some of our therapeutics or maintain the 
secrecy of their trade secrets and know-how. 
If we are unsuccessful in doing so, others may 
market competitive therapeutics at significantly 
lower prices. Alternatively, we may be sued for 
infringement of third-party patent rights. If these 
actions are successful, then we would have to pay 
substantial damages and potentially remove our 
therapeutics from the market. We license certain 
intellectual property rights from third parties. 
If we fail to comply with our obligations under 
these agreements, it may enable the other party 
to terminate the agreement. This could impair 
our freedom to operate and potentially lead to 
third parties preventing us from selling certain 
of our therapeutics.

7  Risks related to enterprise profitability
We expect to continue to incur substantial 
expenditure in further research and development 
activities. There is no guarantee that we will 
become operationally profitable, and, even 
if we do so, we may be unable to sustain 
operational profitability.

8   Risks related to hiring and retaining 

qualified employees and key personnel

We operate in complex and specialized 
business domains and require highly qualified 
and experienced management to implement 
our strategy successfully. We and many of our 
businesses are located in the United States which 
is a highly competitive employment market.

Moreover, the rapid development which is 
envisaged by us may place unsupportable 
demands on our current managers and 
employees, particularly if we cannot attract 
sufficient new employees. There is also the risk that 
we may lose key personnel.

The failure to obtain patent 
protection and maintain the 
secrecy of key information may 
significantly decrease the amount 
of revenue we may receive 
from therapeutic sales. Any 
infringement litigation against 
us may result in the payment of 
substantial damages by us and 
result in a significant decrease in 
our value.

The strategic aim of the 
business is to generate profits 
for our shareholders through 
the commercialization of 
technologies through therapeutic 
sales, strategic partnerships 
and sales of businesses or parts 
thereof. The timing and size 
of these potential inflows are 
uncertain. Should revenues from 
our activities not be achieved, or 
in the event that they are achieved 
but at values significantly less than 
the amount of capital invested, 
then it would be difficult to sustain 
our business.

The failure to attract highly 
effective personnel or the 
loss of key personnel would 
have an adverse impact on 
our ability to continue to grow 
and may negatively affect our 
competitive advantage.

We spend significant resources in the prosecution 
of our patent applications and maintenance of our 
patents, and we have in-house patent counsel and 
patent group to help with these activities. We also 
work with experienced external attorneys and law 
firms to help with the protection, maintenance and 
enforcement of our patents. Third party patent filings 
are monitored to ensure the Group continues to have 
freedom to operate. Confidential information (both 
our own and information belonging to third parties) 
is protected through use of confidential disclosure 
agreements with third parties, and suitable 
provisions relating to confidentiality and intellectual 
property exist in our employment and advisory 
contracts. Licenses are monitored for compliance 
with their terms.

We retain significant cash in order to support funding 
of our Founded Entities and our Internal Programs. 
We have close relationships with a wide group of 
investors and strategic partners to ensure we can 
continue to access the capital markets and additional 
monetization and funding for our businesses. 
Additionally, our Founded Entities are able to 
raise money directly from third party investors and 
strategic partners.

The Board regularly seeks external expertise to 
assess the competitiveness of the compensation 
packages of its senior management. Senior 
management continually monitors and assesses 
compensation levels to ensure we remain 
competitive in the employment market. We maintain 
an extensive recruiting network through our Board 
members, advisors and scientific community 
involvement. We also employ an executive as a full-
time in-house recruiter and retain outside recruiters 
when necessary or advisable. Additionally, we 
are proactive in our retention efforts and include 
incentive-based compensation in the form of 
equity awards and annual bonuses, as well as a 
competitive benefits package. We have a number 
of employee engagement efforts to strengthen 
our PureTech community.

9   Risks related to business, economic or 

public health disruptions

Business, economic, financial or geopolitical 
disruptions or global health concerns could 
seriously harm our development efforts and 
increase our costs and expenses.

We regularly review the business, economic, financial 
and geopolitical environment in which we operate. It 
is possible that we may see further impact as a result 
of current geopolitical tensions. We monitor the 
position of our suppliers, clinical trial sites, regulators, 
providers of financial services and other third parties 
with whom we conduct business. We develop 
and execute contingency plans to address risks 
where appropriate.

Broad-based business, economic, 
financial or geopolitical 
disruptions could adversely 
affect our ongoing or planned 
research and development 
activities. Global health concerns, 
such as a further pandemic, or 
geopolitical events, like the 
ongoing consequences of the 
armed conflicts, could also result 
in social, economic, and labor 
instability in the countries in 
which we operate or the third 
parties with whom we engage. We 
consider the risk to be increasing 
since the prior year and note 
further risks associated with 
the banking system and global 
financial stability. We cannot 
presently predict the scope and 
severity of any potential business 
shutdowns or disruptions, but 
if we or any of the third parties 
with whom we engage, including 
the suppliers, clinical trial sites, 
regulators, providers of financial 
services and other third parties 
with whom we conduct business, 
were to experience shutdowns 
or other business disruptions, 
our ability to conduct our 
business in the manner and on 
the timelines presently planned 
could be materially and negatively 
impacted. It is also possible 
that global health concerns or 
geopolitical events such as these 
ones could disproportionately 
impact the hospitals and clinical 
sites in which we conduct any of 
our current and/or future clinical 
trials, which could have a material 
adverse effect on our business 
and our results of operation and 
financial impact.

PureTech Health plc   Annual Report and Accounts 2023    65  

This assessment was made in consideration of our strong 
financial position, current strategy, and management of 
principal and emerging risks. The following facts support 
the Directors’ view of the viability:

 — We have a cash, cash equivalents and short-term 

investments position of $327.1 million as of December 31, 
2023. Our cash position was strengthened in March 2024 
when we received gross proceeds of $292.7 million from the 
BMS acquisition of Karuna.

 — In March 2024, we announced a proposed capital return 
of $100.0 million to our shareholders by way of a tender 
offer. This announcement reflects the Board’s commitment 
to evaluate its capital allocation regularly, including the 
assessment of opportunities for capital returns to our 
shareholders, subject to the Company’s operational needs.
 — Our cash, cash equivalents and short-term investments are 

highly liquid and readily available.

 — We have control over the spending and strategic 

direction of our Wholly-Owned Programs and Controlled 
Founded Entities.

 — Our business model is structured so that we are not reliant 
on the successful outcomes of any one therapeutic or 
technology within the Wholly-Owned Programs, or any 
Founded Entities.

In addition, the fact that our Wholly-Owned Programs and 
Founded Entities (with the exception of Akili) are currently 
in the research and development stage means that these 
therapeutics, technologies and entities are not reliant on cash 
inflows from product sales or services during the period of this 
assessment. This also means that we are not highly susceptible 
to conditions in one or more market sectors in this time frame. 
The utilization of existing cash, cash equivalents and short-
term investments to advance these therapeutics, technologies 
and entities is within our control, and the spending and 
investment decisions are largely discretionary. Therefore, there 
is management control on reducing discretionary spending 
if unforeseen liquidity risks arise. Although engaging with 
collaboration partners is highly valuable from a validation and, 
in some cases, funding perspective, we are not solely reliant on 
cash flows from such sources over the period of assessment.

Further, the Directors have considered milestone and royalty 
funding based on existing collaboration and partnership 
arrangements, milestone payments from the Royalty Purchase 
Agreement with Royalty Pharma, the ability of the Wholly-
Owned Programs and each Controlled Founded Entity to 
enter into new collaboration agreements, all of which could be 
expected to generate cash in-flows but were not included in 
the assessment. 

Viability

PureTech Health plc Viability Statement
In accordance with the UK Corporate Governance Code 
(Governance Code) published in July 2018, the Directors 
have assessed the prospects of the Company with respect to 
the December 31, 2023 financial position. Based on current 
projections, the Directors believe that the Company has 
sufficient available funding to extend operations into at least 
2027. This period is deemed appropriate having assessed 
the financial health as of December 31, 2023. We expect our 
Wholly-Owned Programs3 to significantly progress during 
this period and for key Controlled Founded Entities2 to reach 
significant development milestones over the period of the 
assessment. As we advance our Wholly-Owned Programs 
and Controlled Founded Entities, our future decisions will be 
driven by the data of our programs. Our current projections 
are consistent with our disciplined R&D approach to advance 
our Wholly-Owned Programs and Controlled Founded 
Entities through the development process and not commit 
resources to further development unless specific thresholds 
for advancement are met. 

The Directors have evaluated our cash and cash equivalents 
and short-term investment of $327.1 million as of December 
31, 2023, the gross proceeds of $292.7 million that we received 
from the Bristol Myers Squibb ("BMS") acquisition of Karuna in 
March 2024, and our proposed capital return of $100.0 million 
by way of a repurchase of ordinary shares to our shareholders 
announced in March 2024, against plausible scenarios. The 
Directors have determined that these amounts are sufficient 
to support our existing and newly launched Founded 
Entities1 (Seaport Therapeutics and Gallop Oncology), and 
our strategy around creating and supporting other Founded 
Entities, should they require it. Additionally, the Directors 
have determined that these amounts are also sufficient for 
the advancement of our Wholly-Owned Programs, to provide 
reasonable returns for our shareholders and to fund the 
Company’s operating costs into at least 2027. 

The Directors' review has considered all of the principal and 
emerging risks identified and focused on the pathway to 
regulatory approval of each therapeutic candidate being 
developed within our Wholly-Owned Programs as well as those 
of our Founded Entities. The Directors reviewed the near-term 
liquidity and considered funding plans of our Wholly-Owned 
Programs and Founded Entities and the near-term capital 
returns to our shareholders in our assessment of long-term 
cash flow projections. It should be noted that the majority of 
funding has been allocated to support the Company’s strategy 
around Founded Entities, alongside the advancement of 
the Wholly-Owned Programs which could become Founded 
entities themselves.

The Directors confirm that they have a reasonable expectation 
that we will continue to operate and meet our obligations as 
they become due over the period of the assessment. In making 
this statement, the Directors carried out a robust assessment 
of the principal and emerging risks, including those that would 
threaten our business model, future performance, solvency 
or liquidity and evaluated plausible scenarios that included 
these risks.

Governance66    PureTech Health plc   Annual Report and Accounts 2023

Viability continued

The Directors note that our ownership stakes in the Founded 
Entities are expected to be illiquid in nature, with the 
exception of our ownership stakes in entities which are 
publicly traded on Nasdaq. While we anticipate holding these 
ownership stakes through the achievement of significant 
milestones or other events, we will continue to be diligent in 
exploring monetization opportunities after key value accretion 
has occurred similar to the execution of the sale of 1,750,000 
common shares of Karuna for an aggregate proceeds of 
$218.1 million in 2021, the sale of 602,100 common shares of 
Karuna for an aggregate proceeds of $115.5 million in 2022, 
the sale of 535,400 common shares of Vor for an aggregate 
proceeds of $3.3 million in 2022, and the sale of 167,579 
common shares of Karuna for an aggregate proceeds of 
$33.3 million in 2023. We also expect that certain of these 
Founded Entities may not be successful, and this could result in 
a loss of the amounts previously invested. For example, Gelesis 
was listed on the New York Stock Exchange as of December 
31, 2022 and was delisted from the New York Stock Exchange 
in April 2023. On October 30, 2023, Gelesis ceased operations 
and filed a voluntary petition for relief under the United States 
bankruptcy code. However, even if certain Founded Entities 
are not successful, our liquidity is expected to remain sufficient 
to achieve the remaining milestone events, fund operational 
costs and provide returns for our shareholders over the period 
of assessment. 

The Directors have concluded, based on our strong financial 
position and readily available cash, cash equivalents and 
short-term investments, that we are highly likely to be able 
to fund our infrastructure requirements, advance our Wholly-
Owned Programs, including trials in more advanced stages, 
and contribute amounts necessary for the Founded Entities 
to reach significant development milestones over the period 
of the assessment and return capital to our shareholders. 
Therefore, there is a reasonable expectation that we have 
adequate resources and will continue to operate and meet our 
obligations over the period of the assessment.

1.  Founded Entities are comprised of the entities which the Company incorporated and announced the incorporation as a Founded Entity externally. It includes certain of the 

Company’s wholly-owned subsidiaries which have been announced by the Company as Founded Entities, Controlled Founded Entities2 and deconsolidated Founded Entities. 
As of December 31, 2023, deconsolidated Founded Entities included Akili Interactive Labs, Inc., Karuna Therapeutics, Inc., Vor Bio, Inc., Gelesis, Inc., Sonde Health, Inc., and 
Vedanta Biosciences, Inc.

2.  Controlled Founded Entities are comprised of the Company’s consolidated operational subsidiaries that currently have already raised third-party dilutive capital. As of December 31, 

2023, Entrega was the only entity under this definition. 

3.  Wholly-Owned Programs are comprised of the Company’s current and future therapeutic candidates and technologies that are developed by the Company's wholly-owned 

subsidiaries, whether they were announced as a Founded Entity or not, and will be advanced through with either the Company's funding or non-dilutive sources of financing. As of 
December 31, 2023, Wholly-Owned Programs were developed by the wholly-owned subsidiaries Alivio Therapeutics, Inc., PureTech LYT, Inc., PureTech LYT 100, Inc. and included 
primarily the programs LYT-100, LYT-200, LYT-300, and the Glyph platform.

the information contained in this discussion and analysis 
or set forth elsewhere in this report, including information

including the risks set forth on pages 60 to 64 and in the 
Additional Information section from pages 186 to 224, our 
actual results could differ materially from the results described 
in or implied by these forward-looking statements.

Our audited Consolidated Financial Statements as 
of December 31, 2023 and 2022, and for the years 
ended December 31, 2023, 2022 and 2021, have been 
prepared in accordance with UK-adopted International 
Financial Reporting Standards ("IFRSs"). The Consolidated 
Financial Statements also comply fully with IFRSs as issued by 
the International Accounting Standards Board ("IASB").

The following discussion contains references to the 
Consolidated Financial Statements of PureTech Health plc 
(the "Parent") and its consolidated subsidiaries, together "the 
Group". These financial statements consolidate PureTech 
Health plc’s subsidiaries and include the Group’s interest in 
associates by way of equity method, as well as investments 
held at fair value. Subsidiaries are those entities over which 
the Group maintains control. Associates are those entities in 
which the Group does not have control for financial accounting 
purposes but maintains significant influence over financial and 
operating policies. Where the Group has neither control nor 
significant influence for financial accounting purposes, or when 
the investment in associates is not in instruments that would 
be considered equity for accounting purposes, we recognize 
our holdings in such entity as an investment at fair value with 
changes in fair value being recorded in the Consolidated 
Statement of Comprehensive Income/(Loss). For purposes of 
our Consolidated Financial Statements, each of our Founded 
Entities1 are considered to be either a “subsidiary", an 
“associate” or an "investment held at fair value" depending on 
whether the Group controls or maintains significant influence 
over the financial and operating policies of the respective 
entity at the respective period end date, and depending 
on the form of the investment. For additional information 
regarding the accounting treatment of these entities, see 
Note 1. Material Accounting Policies to our Consolidated 
Financial Statements included in this report. For additional 
information regarding our operating structure, see “Basis of 
Presentation and Consolidation” below.

Business Background and Results Overview
The business background is discussed above from pages 1 to 
21, which describes the business development of our Wholly-
Owned Programs3 and Founded Entities. 

Our ability to generate product revenue sufficient to achieve 
profitability will depend on the successful development 
and eventual commercialization of one or more therapeutic 
candidates of our wholly-owned or Controlled Founded 
Entities2, which may or may not occur. Historically, certain 
of our Founded Entities' therapeutics received marketing 
authorization from the FDA, but our Wholly-Owned Programs 
have not generated revenue from product sales to date. 

Furthermore, our ability to achieve profitability will largely 
rely on successfully monetizing our investment in founded 
entities, including the sale of rights to royalties, entering 
into strategic partnerships, and other related business 
development activities.

We deconsolidated a number of our Founded Entities, 
specifically Vedanta Biosciences, Inc. ("Vedanta") in 
March 2023, Sonde Health Inc. ("Sonde") in 2022, Karuna 
Therapeutics, Inc. ("Karuna"), Vor Biopharma Inc. ("Vor") and 
Gelesis in 2019, and Akili in 2018.

Any deconsolidation affects our financials in the following 
manner: 

 — our ownership interest does not provide us with a controlling 

financial interest; 

 — we no longer control the Founded Entity's assets and 
liabilities, and as a result, we derecognize the assets, 
liabilities and non-controlling interests related to the 
Founded Entity from our Consolidated Statement of 
Financial Position;

 — we record our retained investment in the Founded Entity 

at fair value; and 

 — the resulting amount of any gain or loss is recognized in our 
Consolidated Statement of Comprehensive Income/(Loss).

We anticipate our expenses to continue to increase 
proportionally in connection with execution of our strategy 
around creating and supporting Founded Entities, as well 
as the ongoing development activities related mostly to the 
advancement into late-stage studies of the clinical programs 
within our Wholly-Owned Programs. We also expect that our 
expenses and capital requirements will increase in the near 
to mid-term as we: 

 — continue our research and development efforts; 
 — seek regulatory approvals for any therapeutic candidates 

that successfully complete clinical trials; and

 — add clinical, scientific, operational, financial and 

management information systems and personnel, including 
personnel to support our therapeutic development and 
potential future commercialization claims.

More specifically, we anticipate that our internal research and 
development spend will increase in the foreseeable future 
as we may initiate additional clinical studies for our existing 
therapeutic candidates, evaluate new therapeutic candidates 
for investment and further development, progress additional 
therapeutic candidates into the clinic, as well as advance our 
technology platforms.

1.  Founded Entities are comprised of the entities which the Company incorporated and announced the incorporation as a Founded Entity externally. It includes certain of the 

Company’s wholly-owned subsidiaries which have been announced by the Company as Founded Entities, Controlled Founded Entities2 and deconsolidated Founded Entities. 
As of December 31, 2023, deconsolidated Founded Entities included Akili Interactive Labs, Inc., Karuna Therapeutics, Inc., Vor Bio, Inc., Gelesis, Inc., Sonde Health, Inc., and 
Vedanta Biosciences, Inc.

2.  Controlled Founded Entities are comprised of the Company’s consolidated operational subsidiaries that currently have already raised third-party dilutive capital. As of December 31, 

2023, Entrega was the only entity under this definition. 

3.  Wholly-Owned Programs are comprised of the Company’s current and future therapeutic candidates and technologies that are developed by the Company's wholly-owned 

subsidiaries, whether they were announced as a Founded Entity or not, and will be advanced through with either the Company's funding or non-dilutive sources of financing. As of 
December 31, 2023, Wholly-Owned Programs were developed by the wholly-owned subsidiaries Alivio Therapeutics, Inc., PureTech LYT, Inc., PureTech LYT 100, Inc. and included 
primarily the programs LYT-100, LYT-200, LYT-300, and the Glyph platform.

Recent Developments (subsequent to December 31, 2023
The Group has evaluated subsequent events after December 
31, 2023 up to the date of issuance, April 25, 2024, of the 
Consolidated Financial Statements, and has not identified 
any recordable or disclosable events not otherwise reported 
in these Consolidated Financial Statements or notes thereto, 
except for the following: 

In January 2024, the Group established two new clinical-
stage entities: Seaport Therapeutics ("Seaport") and Gallop 
Oncology ("Gallop"). Seaport will advance certain central 
nervous system programs and relevant Glyph intellectual 
property. Gallop will advance LYT-200 and other galectin-9 
intellectual property. As of December 31, 2023, the financial 
results of these programs were included in the Wholly-Owned 
Programs segment in the footnotes to the Consolidated 
Financial Statements. Upon raising dilutive third-party 
financing, the financial results of these two entities will be 
included in the Controlled Founded Entities segment to the 
extent that the Group maintains control over these entities.

On May 9, 2022, the Group announced the commencement 
of a $50.0 million share repurchase program the ("Program") 
of its ordinary shares of one pence each. In February 2024, 
the Group completed the Program and has repurchased an 
aggregate of 20,182,863 ordinary shares under the Program. 
These shares have been held as treasury shares and are being 
used to settle the vesting of restricted stock units or exercise 
of options.

In March 2024, Karuna was acquired by Bristol Myers Squibb 
(“BMS”) in accordance with a definitive merger agreement 
signed in December 2023. The Group received total proceeds 
of $292.7 million before income tax in exchange for its holding 
of 886,885 shares of Karuna common stock. 

In March 2024, the Group announced a proposed capital 
return of $100.0 million to its shareholders by way of a tender 
offer (the "Tender Offer"). The Tender Offer is expected to 
be launched in early May, subject to market conditions and 
shareholder approval. If the full $100.0 million is not returned, 
then the Group intends to return any remainder following the 
completion of the Tender Offer, by way of a special dividend.

In April 2024, Seaport Therapeutics, the Group's latest 
Founded Entity, raised $100 million in a Series A financing, 
out of which $32 million was invested by the Group. Following 
the Series A financing, the Group holds equity ownership in 
Seaport of 61.5 percent on a diluted basis. 

In April 2024, the Gelesis' Chapter 7 Trustee provided notice 
that a third party bid to purchase the assets subject to the 
bankruptcy had been accepted as a stalking horse bid, 
subject to Bankruptcy Court approval. If such sale of the 
assets is ultimately approved by the Bankruptcy Court and 
consummated, it is expected that PureTech could recover a 
portion of its investment in Gelesis senior secured convertible 
promissory notes. The ultimate resolution of this matter, any 
potential recovery, and the associated timing remain uncertain. 
The Group has not recorded any amount in its Consolidated 
Financial Statements related to amounts that may be received 
as a result of the bankruptcy process.

Financial Review continued

In addition, with respect to our Founded Entities’ programs, 
we anticipate that we will continue to fund a small portion 
of development costs by strategically participating in such 
companies’ financings when we believe participation in 
such financings is in the best interests of our shareholders. 
The form of any such participation may include investment 
in public or private financings, collaboration, partnership 
arrangements, and/or licensing arrangements, among others. 
Our management and strategic decision makers consider the 
future funding needs of our Founded Entities and evaluate the 
needs and opportunities for returns with respect to each of 
these Founded Entities routinely and on a case-by-case basis.

As a result, we need substantial additional funding in the 
future, following the period described below in the Funding 
Requirement section, to support our continuing operations 
and pursue our growth strategy until such time as we can 
generate sufficient revenue from product sales to support 
our operations, if ever. Until such time, we expect to finance 
our operations through a combination of monetization of our 
interests in our Founded Entities, collaborations with third 
parties, or other sources. We may be unable to raise additional 
funds or enter into such other agreements or arrangements 
when needed on favorable terms, or at all. If we are unable 
to raise capital or enter into such agreements, as and when 
needed, we may have to delay, scale back or discontinue the 
development and commercialization of one or more of our 
wholly-owned therapeutic candidates. 

Measuring Performance
The Financial Review discusses our operating and financial 
performance, our cash flows and liquidity as well as our 
financial position and our resources. The results for each 
period are compared primarily with the results of the 
comparative period in the prior year.

Reported Performance 
Reported performance considers all factors that have affected 
the results of our business, as reflected in our Consolidated 
Financial Statements.

Core Performance
Core performance measures are alternative performance 
measures which are adjusted and non-IFRS measures. These 
measures cannot be derived directly from our Consolidated 
Financial Statements. We believe that these non-IFRS 
performance measures, when provided in combination with 
reported performance, will provide investors, analysts and 
other stakeholders with helpful complementary information to 
better understand our financial performance and our financial 
position from period to period. The measures are also used 
by management for planning and reporting purposes. The 
measures are not substitutable for IFRS financial information 
and should not be considered superior to financial information 
presented in accordance with IFRS.

Cash flow and liquidity
PureTech Level cash, cash 
equivalents and short-term 
investments

Measure type: Core performance
Definition: Cash and cash 
equivalents and short-term

Why we use it: PureTech Level 
cash, cash equivalents and short-

that provides valuable additional 
information with respect to cash, 
cash equivalents and short-term 
investments available to fund the 
Wholly-Owned Programs and make 
certain investments in Founded 
Entities.

Basis of Presentation and Consolidation
Our Consolidated Financial Information consolidates the 
financial information of PureTech Health plc, as well as its 
subsidiaries, and includes our interest in associates and 
investments held at fair value.

Basis for Segmentation 
Our Directors are our strategic decision-makers. Our operating 
segments are determined based on the financial information 
provided to our Directors periodically for the purposes of 
allocating resources and assessing performance. During the 
second half of 2023, we changed the financial information that 
was regularly reviewed by the Directors to allocate resources 
and assess performance. We have determined each of our 
Wholly-Owned Programs represents an operating segment, 
and we have aggregated each of these operating segments 
into one reportable segment, the Wholly-Owned Programs 
segment, given the high level of operational and financial 
similarities across our Wholly-Owned Programs. Each of our 
Controlled Founded Entities represents an operating segment. 
We aggregate each Controlled Founded Entity operating 
segment into one reportable segment, the Controlled 
Founded Entities segment. For our entities that do not meet 
the definition of an operating segment, we present this 
information in the Parent Company & Other column in our 
segment footnote to reconcile the information in this footnote 
to our Consolidated Financial Statements. Substantially all of 
our revenue and profit generating activities are generated 
within the United States and, accordingly, no geographical 
disclosures are provided. 

Following is the description of our reportable segments:

Wholly-Owned Programs
The Wholly-Owned Programs segment is advancing Wholly-
Owned Programs which are focused on treatments for 
patients with devastating diseases. The Wholly-Owned 
Programs segment is comprised of the technologies that are 
wholly-owned and will be advanced through with either the 
Group's funding or non-dilutive sources of financing. The 
operational management of the Wholly-Owned Programs 
segment is conducted by the PureTech Health team, which 
is responsible for the strategy, business development, and 
research and development. 

Controlled Founded Entities
The Controlled Founded Entities segment is comprised of the 
Group’s consolidated operational subsidiaries as of December 
31, 2023 that either have, or have plans to hire, independent 
management teams and currently have already raised third-
party dilutive capital. These subsidiaries have active research 
and development programs and either have entered into or 
plan to seek an equity or debt investment partner, who will 
provide additional industry knowledge and access to networks, 
as well as additional funding to continue the pursued growth 
of the company. 

The Group’s entities that were determined not to meet 
the definition of an operating segment are included in the 
Parent Company and Other column to reconcile the segment 
information to the financial statements. This column captures 
activities not directly attributable to the Group’s operating 
segment and includes the activities of the Parent, corporate 
support functions and certain research and development 
support functions that are not directly attributable to a 
strategic business segment as well as the elimination of 
intercompany transactions. This column also captures the 
operating results for our deconsolidated entities through the 
date of deconsolidation (e.g. Vedanta in 2023 and Sonde in 
2022), and accounting for our holdings in Founded Entities for 
which control has been lost, which primarily represents: the 
activity associated with deconsolidating an entity when we no 
longer control the entity (e.g. Vedanta in 2023 and Sonde in 
2022), the gain or loss on our investments accounted for at fair 
value (e.g. our ownership stakes in Karuna, Vor and Akili) and 
our net income or loss of associates accounted for using the 
equity method. 

In January 2024, the Group launched two new Founded 
Entities (Seaport Therapeutics and Gallop Oncology) to 
advance certain programs from the Wholly-Owned Programs. 
Seaport Therapeutics will advance certain central nervous 
system programs and relevant Glyph intellectual property. 
Gallop Oncology will advance LYT-200 and other galectin-9 
intellectual property. The financial results of these programs 
were included in the Wholly-Owned Programs segment in 
the footnotes to the Consolidated Financial Statements as of 
December 31, 2023 and 2022, and for the three years ended 
December 31, 2023, 2022 and 2021, respectively. Upon raising 
dilutive third-party financing, the financial results of these two 
entities will be included in the Controlled Founded Entities 
segment to the extent that the Group maintains control over 
these entities.

The table below summarizes the entities that comprised each 
of our segments as of December 31, 2023:

Entities’ therapeutic candidates is highly uncertain. As such, 
at this time, we cannot reasonably estimate or know the nature, 
timing and estimated costs of the efforts that will be necessary 
to complete the remainder of the development of these 
therapeutic candidates through our funding or in conjunction 
with our external partners. We are also unable to predict 
when, if ever, material net cash inflows will commence from our 
wholly-owned or our Founded Entities’ therapeutic candidates. 
This is due to the numerous risks and uncertainties associated 
with developing therapeutics, including the uncertainty of:

 — progressing research and development of our Wholly-

Owned Programs and Founded Entities and continuing 
to progress our various technology platforms and other 
potential therapeutic candidates based on previous human 
efficacy and clinically validated biology within our Wholly-
Owned Programs and Founded Entities;

 — establishing an appropriate safety profile with investigational 

new drug application; 

 — the success of our Founded Entities and their need for 

additional capital; 

 — identifying new therapeutic candidates to add to our Wholly-

Owned Programs or Founded Entities; 

 — successful enrollment in, and the initiation and completion 

of, clinical trials; 

 — the timing, receipt and terms of any marketing approvals 

from applicable regulatory authorities; 

 — establishing commercial manufacturing capabilities or 
making arrangements with third-party manufacturers; 
 — addressing any competing technological and market 

developments, as well as any changes in governmental 
regulations; 

 — negotiating favorable terms in any collaboration, licensing or 
other arrangements into which we may enter and performing 
our obligations under such arrangements; 

 — maintaining, protecting and expanding our portfolio of 

intellectual property rights, including patents, trade secrets 
and know-how, as well as obtaining and maintaining 
regulatory exclusivity for our wholly-owned and our Founded 
Entities’ therapeutic candidates; 

 — continued acceptable safety profile of our therapeutics, 

if any, following approval; and 

 — attracting, hiring and retaining qualified personnel. 

A change in the outcome of any of these variables with respect 
to the development of a therapeutic candidate could mean 
a significant change in the costs and timing associated with 
the development of that therapeutic candidate. For example, 
the FDA, the EMA, or another comparable foreign regulatory 
authority may require us to conduct clinical trials beyond 
those that we anticipate will be required for the completion 
of clinical development of a therapeutic candidate, or we may 
experience significant trial delays due to patient enrollment or 
other reasons, in which case we would be required to expend 
significant additional financial resources and time on the 
completion of clinical development. In addition, we may obtain 
unexpected results from our clinical trials, and we may elect to 
discontinue, delay or modify clinical trials of some therapeutic 
candidates or focus on others. Identifying potential therapeutic 
candidates and conducting preclinical testing and clinical 
trials is a time-consuming, expensive and uncertain process 
that takes years to complete, and we may never generate 
the necessary data or results required to obtain marketing 
approval and achieve product sales. In addition, our wholly-
owned and our Founded Entities’ therapeutic candidates, 
if approved, may not achieve commercial success. 

Financial Review continued

Components of Our Results of Operations 
Revenue
To date, we have not generated any meaningful revenue 
from product sales and we do not expect to generate any 
meaningful revenue from product sales in the near future. 
We derive our revenue from the following: 

Contract revenue
We generate revenue primarily from licenses, services 
and collaboration agreements, including amounts that are 
recognized related to upfront payments, milestone payments, 
royalties and amounts due to us for research and development 
services. In the future, revenue may include additional 
milestone payments and royalties on any net product sales 
under our licensing agreements. We expect that any revenue 
we generate will fluctuate from period to period as a result of 
the timing and amount of license, research and development 
services and milestone and other payments. 

Grant Revenue
Grant revenue is derived from grant awards we receive from 
governmental agencies and non-profit organizations for 
certain qualified research and development expenses. We 
recognize grants from governmental agencies and non-profit 
organizations as grant revenue in the Consolidated Statement 
of Comprehensive Income/(Loss), gross of the expenditures 
that were related to obtaining the grant, when there is 
reasonable assurance that we will comply with the conditions 
within the grant agreement and there is reasonable assurance 
that payments under the grants will be received. We evaluate 
the conditions of each grant as of each reporting date to 
ensure that we have reasonable assurance of meeting the 
conditions of each grant arrangement, and it is expected that 
the grant payment will be received as a result of meeting the 
necessary conditions.

Operating Expenses 
Research and Development Expenses 
Research and development expenses consist primarily 
of costs incurred for our research activities, including our 
discovery efforts, and the development of our wholly-owned 
and our Controlled Founded Entities’ therapeutic candidates, 
which include: 

 — employee-related expenses, including salaries, related 

benefits and equity-based compensation; 

 — expenses incurred in connection with the preclinical and 

clinical development of our wholly-owned and our Founded 
Entities’ therapeutic candidates, including our agreements 
with contract research organizations; 

 — expenses incurred under agreements with consultants who 

supplement our internal capabilities; 

 — the cost of lab supplies and acquiring, developing and 
manufacturing preclinical study materials and clinical 
trial materials; 

 — costs related to compliance with regulatory requirements; 

and 

 — facilities, depreciation and other expenses, which include 
direct and allocated expenses for rent and maintenance 
of facilities, insurance and other operating costs. 

We expense all research costs in the periods in which they 
are incurred and development costs are capitalized only if 
certain criteria are met. For the periods presented, we have 
not capitalized any development costs since we have not met 
the necessary criteria required for capitalization. 

Research and development activities are central to 
our business model. We expect that our research and 
development expenses will continue to increase for the 
foreseeable future in connection with our planned preclinical 
and clinical development activities in the near term and in 
the future related to our Wholly-Owned Programs and our 
existing, newly established and future Founded Entities. The 
successful development of our wholly-owned and our Founded 

Governance72    PureTech Health plc   Annual Report and Accounts 2023

Financial Review continued

General and Administrative Expenses 
General and administrative expenses consist primarily 
of salaries and other related costs, including stock-based 
compensation, for personnel in our executive, finance, 
corporate and business development and administrative 
functions. General and administrative expenses also include 
professional fees for legal, patent, accounting, auditing, 
tax and consulting services, travel expenses and facility-
related expenses, which include direct depreciation costs 
and allocated expenses for rent and maintenance of facilities 
and other operating costs. 

We expect that our general and administrative expenses 
will increase in the future as we support our increased 
number of consolidated Founded Entities, continued 
research and development to support our Wholly-Owned 
Programs and our technology platforms, as well as potential 
commercialization of our Controlled Founded Entities' 
portfolio of therapeutic candidates.

Total Other Income/(Expense)
Gain on Deconsolidation of Subsidiary
Upon losing control over a subsidiary, the assets and liabilities 
are derecognized along with any related non-controlling 
interest (“NCI”). Any interest retained in the former subsidiary 
is measured at fair value when control is lost. Any resulting 
gain or loss is recognized as profit or loss in the Consolidated 
Statement of Comprehensive Income/(Loss).

Gain/(Loss) on Investments Held at Fair Value 
Investments held at fair value include both unlisted and 
listed securities held by us, which include investments in 
Akili, Karuna, Vor, Vedanta and Sonde and other insignificant 
investments. We account for investments in convertible 
preferred shares in accordance with IFRS 9 as investments 
held at fair value when the preferred shares do not provide 
their holders with access to returns associated with a residual 
equity interest. Under IFRS 9, the preferred share investments 
are categorized as debt instruments that are presented at fair 
value through profit and loss because the amounts receivable 
do not represent solely payments of principal and interest.

Realized Gain/(Loss) on Sale of Investments
Realized gain/(loss) on sale of investments held at fair value 
relates to realized differences in the per share disposal price 
of a listed security as compared to the per share exchange 
quoted price at the time of disposal. The realized loss in 
2021 is attributable to a block sale discount, due to a variety 
of market factors, primarily the number of shares being 
transacted was significantly larger than the daily trading 
volume of the security. The realized loss in 2022 is attributable 
to the settlement of call options written by the Group on 
Karuna stock. The amount in 2023 is not significant.

Gain/(Loss) on Investments in Notes from Associates
Gain/(loss) on investments in notes from associates relates 
to our investment in the notes from Gelesis and Vedanta. 
We account for these notes in accordance with IFRS 9 
as investments held at fair value, with changes in fair 
value recognized through the Consolidated Statement of 
Comprehensive Income/(Loss). The amount in 2023 is primarily 
attributable to a decrease in the fair value of our notes from 
Gelesis. On October 30, 2023, Gelesis ceased operations and 
filed a voluntary petition for relief under the United States 
bankruptcy code.

Other Income (Expense) 
Other income (expense) consists primarily of gains and losses 
on financial instruments. In 2022, it relates primarily to the 
Backstop agreement with Gelesis. 

Finance Income/(Costs) 
Finance costs consist of loan interest expense, interest 
expense due to accretion of and adjustment to the sale of 
future royalties liability as well as the changes in the fair value 
of certain liabilities associated with financing transactions, 
mainly preferred share liabilities in respect of preferred shares 
issued by our non-wholly owned subsidiaries to third parties. 
Finance income consists of interest income on funds invested 
in money market funds and U.S. treasuries. 

Share of Net Income (Loss) of Associates Accounted for Using 
the Equity Method, Gain on Dilution of Ownership Interest and 
Impairment of Investment in Associates
Associates are accounted for using the equity method 
(equity accounted investees) and are initially recognized at 
cost, or if recognized upon deconsolidation, they are initially 
recorded at fair value at the date of deconsolidation. The 
Consolidated Financial Statements include our share of 
the total comprehensive income/(loss) of equity accounted 
investees, from the date that significant influence commences 
until the date that significant influence ceases. When the share 
of losses exceeds the net investment in the investee, including 
the investment considered long-term interests, the carrying 
amount is reduced to nil and recognition of further losses is 
discontinued except to the extent that we have incurred legal 
or constructive obligations or made payments on behalf of 
an investee.

We compare the recoverable amount of the investment to its 
carrying amount on a go-forward basis and determine the 
need for impairment. 

When our share in the equity of the investee changes as a 
result of equity transactions in the investee (related to financing 
events of the investee), we calculate a gain or loss on such 
change in ownership and related share in the investee's equity. 
During the year ended December 31, 2022, we recorded a gain 
on dilution of our ownership interest in Gelesis.

In 2023, we recorded our share of the net loss of Gelesis 
which reduced the carrying amount of our investment to zero. 
On October 30, 2023, Gelesis ceased operations and our 
significant influence in Gelesis ceased.

Income Tax 
The amount of taxes currently payable or refundable is 
accrued, and deferred tax assets and liabilities are recognized 
for the estimated future tax consequences attributable to 
differences between the financial statement carrying amount 
of existing assets and liabilities and their respective tax bases. 
Deferred tax assets are also recognized for realizable loss and 
tax credit carryforwards. Deferred tax assets and liabilities are 
measured using substantively enacted tax rates in effect for 
the year in which those temporary differences are expected 
to be recovered or settled. Net deferred tax assets are not 
recorded if we do not assess their realization as probable. 
The effect on deferred tax assets and liabilities of a change 
in income tax rates is recognized in our financial statements 
in the period that includes the substantive enactment date 
or the change in tax status.

Our total revenue was $3.3 million for the year ended December 31, 2023, a decrease of $12.3 million, or 79 percent compared 
to the year ended December 31, 2022. The decrease was primarily attributable to a decrease of $10.9 million in grant revenue, 
mainly as a result of inclusion of Vedanta’s activities only for a part of the year through its deconsolidation in March 2023, and 
a decrease of $2.0 million as a result of decreased grant-related activities. The decrease was also attributed to a decrease of 
$1.3 million in contract revenue due to the conclusion of certain collaboration agreements, as well as a decrease of $0.6 million 
due primarily to the discontinuation of royalty revenue from Gelesis as Gelesis ceased operations in October 2023.

Our research and development expenses were $96.2 million for the year ended December 31, 2023, a decrease of $56.2 million, 
or 37 percent compared to the year ended December 31, 2022. The change was primarily attributable to a decrease of 
$26.6 million in research and development expenses incurred by the Wholly-Owned Programs, out of which $13.1 million is due 
to prioritization of research and development projects, whereby the Group elected to focus on programs where it believes it has 
the highest probability of success and reduced efforts in research and clinical stage projects where such probability of success 
is lower. The program prioritization and reduction in the research activities further resulted in a decrease of $6.3 million in payroll 
and headcount related costs, and $1.3 million of impairment cost of fixed assets related to write down of lab equipment that 
was previously used by the research team. In addition, there was a decrease of $12.4 million, mainly in contract manufacturing 
expenses in the year ended December 31, 2023, as compared to the year ended December 31, 2022, due to the ramp up of 
clinical manufacturing efforts in the year ended December 31, 2022, in preparation of the start of new clinical studies. These 
decreases in research and development expenses were partially offset with increases of $4.7 million in consulting fee and outside 
services. The decrease in research and development expenses was also attributable to a decrease of $29.3 million in the Parent 
Company and Other as a result of inclusion of Vedanta’s activities only for a part of the year 2023 through its deconsolidation 
in March 2023, as compared with inclusion of the results for the full year in the year ended December 31, 2022.

Our general and administrative expenses were $53.3 million for the year ended December 31, 2023, a decrease of $7.7 million, 
or 13 percent compared to the year ended December 31, 2022. The change was attributable to a decrease of $13.6 million in 
Parent Company and Other offset by increases of $5.7 million, and $0.1 million in the Wholly-Owned Programs segment and 
the Controlled Founded Entities segment, respectively. The decrease in the Parent Company and Other in 2023 was primarily 
attributable to the inclusion of Vedanta’s activities only for a part of the year 2023 through its deconsolidation in March 2023, 
as compared with inclusion of the results for the full year in the year ended December 31, 2022, partially offset with an increase 
in consulting fees related to project evaluation and employee compensation costs. The increases in the Wholly-Owned Programs 
segment and the Controlled Founded Entities segments were primarily driven by increases, in management fees, charged by 
the Parent Company during the year ended December 31, 2023 as compared to the year ended December 31, 2022.

Total Other Income/(Expense)
Total other income was $111.1 million for the year ended December 31, 2023 compared to a loss of $26.0 million for the year 
ended December 31, 2022, reflecting a change of $137.1 million, or 528%. The increase in other income was primarily attributable 
to the following:

 — a gain from investments held at fair value of $77.9 million primarily attributed to an increase in fair value of Karuna shares for 
the year ended December 31, 2023, compared to a loss of $32.1 million for the year ended December 31, 2022, reflecting 
an increase in other income of $110.0 million. 

 — a gain from deconsolidation of Vedanta of $61.8 million for the year ended December 31, 2023, compared to a gain from 

deconsolidation of Sonde of $27.3 million for the year ended December 31, 2022, reflecting an increase in other income of 
$34.5 million. 

 — a decrease of $29.2 million in realized loss from the sale of investments. 

These increases in total other income were partially offset by a loss from investments in notes from associates of $27.6 million 
primarily due to Gelesis ceasing operations in October 2023, for the year ended December 31, 2023, while no such loss occurred 
during the year ended December 31, 2022, as well as a decrease in other income of $9.0 million due to a gain of $7.6 million in 
respect of the Gelesis back-stop agreement recorded during the year ended December 31, 2022.

Net Finance Income/(Costs)
Net finance income was $5.1 million for the year 
ended December 31, 2023, compared to net finance income 
of $138.9 million for the year ended December 31, 2022, 
reflecting a decrease of $133.8 million or 96 percent in net 
finance Income. The decrease was primarily attributable to the 
net change in fair value of subsidiaries' financial instrument 
liabilities: during the year ended December 31, 2023, net 
change in fair value of subsidiaries' preferred shares, warrant 
and convertible note liabilities was an income of $2.6 million, 
while for the year ended December 31, 2022, such change 
was an income of $137.1 million, primarily related to change 
in fair value of Vedanta preferred share liabilities, leading to 
decrease in income of $134.4 million. In addition, the decrease 
in net finance income is attributable to non-cash interest 
expenses in the amount of $10.2 million recorded on the sale 
of future royalties liability, during the year ended December 
31, 2023, with no such corresponding expense, or liability, 
in the year ended December 31, 2022. This decrease in net 
finance income was partially offset by an increase in interest 
income in the amount of $10.2 million due to higher interest 
rates and yields earned on financial assets and a decrease of 
$0.5 million in contractual interest expense during the year 
ended December 31, 2023, as compared to the year ended 
December 31, 2022.

Share of Net Income/(loss) of Associates Accounted for Using 
the Equity Method 
For the year ended December 31, 2023, the share in net loss of 
associates reported under the equity method was $6.1 million 
as compared to the share in net loss of associates of 
$27.7 million for the year ended December 31, 2022, resulting 
in a net decrease in loss of $21.7 million. The decrease was 
primarily attributable to a decrease in Gelesis losses incurred 
in the year ended December 31, 2023, due to the reduction 
in the carrying value of our investment to zero.

Gain/(Loss) on Dilution of Ownership Interest in Associates 
and Impairment of Investment in Associates
During the year ended December 31, 2022, the Group 
recorded a gain on dilution of its equity ownership interest 
in Gelesis of $28.2 million as a result of the completion of the 
merger with CapStar on January 13, 2022. In addition, during 
the year ended December 31, 2022, the Group recorded an 
impairment loss of $8.4 million in respect of its investment in 
Gelesis. No such gains or impairment was incurred in the year 
ended December 31, 2023.

Taxation 
Income tax expense was an expense of $30.5 million for 
the year ended December 31, 2023, as compared to a 
benefit of $55.7 million for the year ended December 
31, 2022, reflecting an increase in income tax expense of 
$86.2 million. The increase in the income tax expense in the 
year ended December 31, 2023, was primarily attributable to 
lower pre-tax loss in the tax consolidated U.S. group, the tax 
in respect of the sale of future royalties to Royalty Pharma and 
the impact of derecognizing previously recognized deferred 
tax assets that are no longer expected to be utilized. For 
the year ended December 31, 2022, the Group recorded 
an income tax benefit, primarily attributable to the increase 
in gains that are non-taxable. For a full reconciliation from 
the statutory tax rate to the effective tax rate, see Note 27. 
Taxation to our Consolidated Financial Statements.

Comparison of the Years Ended December 31, 2022 and 2021
For the comparison of 2022 to 2021, refer to Part I, Item 5 
“Operating and Financial Review and Prospects” of our Annual 
Report on Form 20-F for the year ended December 31, 2022.

PureTech Health plc   Annual Report and Accounts 2023    75  

Material Accounting Policies and Significant Judgments 
and Estimates 
Our management’s discussion and analysis of our financial 
condition and results of operations is based on our financial 
statements, which we have prepared in accordance with 
UK-adopted International Financial Reporting Standards 
("IFRSs"). The Consolidated Financial Statements also comply 
fully with IFRSs as issued by the International Accounting 
Standards Board ("IASB"). In the preparation of these financial 
statements, we are required to make judgments, estimates 
and assumptions about the carrying amounts of assets and 
liabilities that are not readily apparent from other sources. 
The estimates and associated assumptions are based on 
historical experience and other factors that are considered 
to be relevant. Actual results may differ from these estimates 
under different assumptions or conditions. 

Our estimates and assumptions are reviewed on an ongoing 
basis. Revisions to accounting estimates are recognized in the 
period in which the estimate is revised if the revision affects 
only that period or in the period of the revisions and future 
periods if the revision affects both current and future periods. 

While our significant accounting policies are described in more 
detail in the notes to our Consolidated Financial Statements 
appearing at the end of this report, we believe the following 
accounting policies to be most critical to the judgments and 
estimates used in the preparation of our financial statements. 
See Note 1. Material Accounting Policies to our Consolidated 
Financial Statements for a further detailed description of our 
significant accounting policies. 

Financial instruments 
We account for our financial instruments according to IFRS 
9. In accordance with IFRS 9, we carry certain financial assets 
and financial liabilities at fair value, with changes in fair value 
through profit and loss ("FVTPL"). Valuation of these financial 
instruments includes determining the appropriate valuation 
methodology and making certain estimates such as the future 
expected returns on the financial instrument in different 
scenarios, appropriate discount rate, volatility, and term to exit.

In accordance with IFRS 9, when issuing preferred shares in 
our subsidiaries, we determine the classification of financial 
instruments in terms of liability or equity. Such determination 
involves judgement. These judgements include an assessment 
of whether the financial instruments include any embedded 
derivative features, whether they include contractual 
obligations upon us to deliver cash or other financial assets 
or to exchange financial assets or financial liabilities with 
another party at any point in the future prior to liquidation, and 
whether that obligation will be settled by exchanging a fixed 
amount of cash or other financial assets for a fixed number of 
the Group's equity instruments.

Consolidation
The Consolidated Financial Statements include the financial 
statements of the Group and the entities it controls. Based 
on the applicable accounting rules, we control an investee 
when we are exposed, or have rights, to variable returns 
from our involvement with the investee and have the ability 
to affect those returns through our power over the investee. 
Therefore an assessment is required to determine whether 
we have (i) power over the investee; (ii) exposure, or rights, to 
variable returns from our involvement with the investee; and 
(iii) the ability to use our power over the investee to affect 
the amount of our returns. Judgement is required to perform 
such assessment and it requires that we consider, among 
others, activities that most significantly affect the returns of the 
investee, our voting shares, representation on the board, rights 
to appoint board members and management, shareholders 
agreements, de facto power and other contributing factors.

Governance76    PureTech Health plc   Annual Report and Accounts 2023

Financial Review continued

Sale of Future Royalties Liability
We account for the sale of future royalties liability as a financial 
liability, as we continue to hold the rights under the royalty 
bearing licensing agreement and have a contractual obligation 
to deliver cash to an investor for a portion of the royalty 
we receive. Interest on the sale of future royalties liability is 
recognized using the effective interest rate over the life of the 
related royalty stream.

The sale of future royalties liability and the related interest 
expense are based on our current estimates of future royalties 
expected to be paid over the life of the arrangement. 
Forecasts are updated periodically as new data is obtained. 
Any increases, decreases or a shift in timing of estimated 
cash flows require us to re-calculate the amortized cost of 
the sale of future royalties liability as the present value of the 
estimated future contractual cash flows that are discounted at 
the liability’s original effective interest rate. The adjustment is 
recognized immediately in profit or loss as income or expense.

In determining the appropriate accounting treatment for 
the Royalty Purchase Agreement, management applied 
significant judgement.

Investment in Associates
When we do not control an investee but maintain significant 
influence over the financial and operating policies of the 
investee, the investee is an associate. Significant influence 
is presumed to exist when we hold 20 percent or more 
of the voting power of an entity, unless it can be clearly 
demonstrated that this is not the case. We evaluate if we 
maintain significant influence over associates by assessing if 
we have the power to participate in the financial and operating 
policy decisions of the associate.

Associates are accounted for using the equity method 
(equity accounted investees) and are initially recognized at 
cost, or if recognized upon deconsolidation, they are initially 
recorded at fair value at the date of deconsolidation. The 
Consolidated Financial Statements include our share of the 
total comprehensive income or loss of equity accounted 
investees, from the date that significant influence commences 
until the date that significant influence ceases. When our share 
of losses exceeds the net investment in an equity accounted 
investee, including investments considered to be long-term 
interests ("LTI"), the carrying amount is reduced to zero and 
recognition of further losses is discontinued except to the 
extent that we have incurred legal or constructive obligations 
or made payments on behalf of an investee. To the extent we 
hold interests in associates that are not providing access to 
returns underlying ownership interests, the instrument held by 
us is accounted for in accordance with IFRS 9.

Judgement is required in order to determine whether we 
have significant influence over financial and operating policies 
of investees. This judgement includes, among others, an 
assessment whether we have representation on the board 
of the investee, whether we participate in the policy-making 

processes of the investee, whether there is any interchange of 
managerial personnel, whether there is any essential technical 
information provided to the investee, and if there are any 
transactions between us and the investee.

Judgement is also required to determine which instruments we 
hold in the investee form part of the investment in associates, 
which is accounted for under IAS 28 and scoped out of IFRS 
9, and which instruments are separate financial instruments 
that fall under the scope of IFRS 9. This judgement includes an 
assessment of the characteristics of the financial instrument of 
the investee held by us and whether such financial instrument 
provides access to returns underlying an ownership interest.

Where the Group has other investments in an equity 
accounted investee that are not accounted for under IAS 28, 
judgement is required in determining if such investments 
constitute long-term interests for the purposes of IAS 28. 
This determination is based on the individual facts and 
circumstances and characteristics of each investment, but is 
driven, among other factors, by the intention and likelihood to 
settle the instrument through redemption or repayment in the 
foreseeable future, and whether or not the investment is likely 
to be converted to common stock or other equity instruments. 

Recent Accounting Pronouncements 
For information on recent accounting pronouncements, 
see Note 2. New Standards and Interpretations to our 
Consolidated Financial Statements. 

Cash Flow and Liquidity
Our cash flows may fluctuate and are difficult to forecast and 
will depend on many factors, including:

 — the expenses incurred in the development of wholly-owned 
and Controlled Founded Entities' therapeutic candidates;

 — the revenue, if any, generated by wholly-owned and 
Controlled-Founded Entities' therapeutic candidates;
 — the revenue, if any, generated from licensing and royalty 

agreements with Founded Entities;

 — the financing requirements of the Wholly-Owned Programs 

and our Founded Entities; and

 — the investing activities including the monetization, through 

sale, of shares held in our public Founded Entities.

As of December 31, 2023, we had cash and cash equivalents 
of $191.1 million and short-term investments of $136.1 million. 
As of December 31, 2023, we had PureTech Level cash, cash 
equivalents and short-term investments of $326.0 million. 
PureTech Level cash, cash equivalents and short-term 
investments is a non-IFRS measure (for a definition of PureTech 
Level cash, cash equivalents and short-term investments and a 
reconciliation with the IFRS number, see the section Measuring 
Performance earlier in this Financial Review). In March 2024, we 
received total proceeds of $292.7 million before income tax in 
exchange for our holding of 886,885 shares of Karuna common 
stock as a result of the completion of Karuna acquisition by 
Bristol Myers Squibb (“BMS”).

Funding Requirements 
We have incurred operating losses since inception. Based on 
our current plans, we believe our existing financial assets as of 
December 31, 2023, will be sufficient to fund our operations 
and capital expenditure requirements into at least 2027. We 
expect to incur substantial additional expenditures in the 
near term to support our ongoing and future activities. We 
anticipate to continue to incur net operating losses for the 
foreseeable future to support our existing Founded Entities 
and newly launched Founded Entities (Seaport Therapeutics 
and Gallop Oncology), and our strategy around creating and 
supporting other Founded Entities, should they require it, to 
reach significant development milestones over the period of 
the assessment in conjunction with our external partners. We 
also expect to incur significant costs to advance our Wholly-
Owned Programs, to continue research and development 
efforts, to discover and progress new therapeutic candidates 
and to fund the Group’s operating costs into at least 2027. 
Our ability to fund our therapeutic development and clinical 
operations as well as ability to fund our existing, newly 
founded and future Founded Entities, will depend on the 
amount and timing of cash received from planned financings, 
monetization of shares of public Founded Entities and 
potential business development activities. Our future capital 
requirements will depend on many factors, including: 

 — the costs, timing and outcomes of clinical trials and 

regulatory reviews associated with our wholly-owned 
therapeutic candidates; 

 — the costs of preparing, filing and prosecuting patent 

applications and maintaining, enforcing and defending 
intellectual property related claims; 

 — the emergence of competing technologies and products and 

other adverse marketing developments; 

 — the effect on our therapeutic and product development 
activities of actions taken by the U.S. Food and Drug 
Administration (“FDA”), the European Medicines Agency 
(“EMA”) or other regulatory authorities; 

 — the number and types of future therapeutics we develop and 

support with the goal of commercialization;

 — The costs, timing and outcomes of identifying, evaluating, 
and investing in technologies and drug candidates to 
develop as Wholly-Owned Programs or as Founded Entities; 
and 

 — the success of our Founded Entities and their need for 

additional capital.

A change in the outcome of any of these or other variables 
with respect to the development of any of our wholly-owned 
therapeutic candidates could significantly change the 
costs and timing associated with the development of that 
therapeutic candidate.

Further, our operating plans may change, and we may 
need additional funds to meet operational needs and 
capital requirements for clinical trials and other research 
and development activities. We currently have no credit 
facility or other committed sources of capital beyond 
our existing financial assets. Because of the numerous 
risks and uncertainties associated with the development 
and commercialization of our wholly-owned therapeutic 
candidates, we have only a general estimate of the amounts 
of increased capital outlays and operating expenditures 
associated with our current and anticipated therapeutic 
development programs and these may change in the future.

Operating Activities 
Net cash used in operating activities was $105.9 million 
for the year ended December 31, 2023, as compared to 
$178.8 million for the year ended December 31, 2022, resulting 
in a decrease of $72.9 million in net cash used in operating 
activities. The decrease in outflows is primarily attributable to 
our lower operating loss mainly due to a decrease in research 
and development activities in the Wholly-Owned Programs 
and Controlled Founded Entities and a decrease of operating 
cash flows as a result of the deconsolidation of Vedanta on 
March 1, 2023. 

Net cash used in operating activities was $178.8 million for 
the year ended December 31, 2022, as compared to $158.3 
million for the year ended December 31, 2021, resulting in 
an increase of $20.5 million in net cash used in operating 
activities. The increase in outflows is primarily attributable to 
our higher operating loss mainly due to an increase in research 
and development activities in the Wholly-Owned Programs 
segment, partially offset by the timing of receipts and 
payments in the normal course of business.

Investing Activities 
Net cash provided by investing activities was $69.0 million for 
the year ended December 31, 2023, as compared to net cash 
outflow of $107.2 million for the year ended December 31, 
2022, resulting in an increase of $176.2 million in net cash from 
investing activities. The increase in net cash from investing 
activities was primarily attributable to increased cash inflow 
from short-term investment activities (redemptions, net of 
purchases) amounting to $264.4 million, partially offset by a 
reduction in proceeds from the sale of investments held at fair 
value of $85.4 million.

Net cash used in investing activities was $107.2 million for the 
year ended December 31, 2022, as compared to cash inflows 
of $197,375 for the year ended December 31, 2021, resulting 
in a decrease of $304.6 million in net cash resulting from 
investing activities. The decrease in the net cash resulting 
from investing activities was primarily attributed to a decrease 
in proceeds from the sale of investments held at fair value of 
$99.4 million and to the purchase of short-term investments, 
net of redemptions amounted to $198.7 million for the year 
ended December 31, 2022. 

Financing Activities 
Net cash provided by financing activities was $78.1 million 
for the year ended December 31, 2023, as compared to 
net cash used in financing activities of $29.8 million for the 
year ended December 31, 2022, resulting in an increase of 
$108.0 million in the net cash provided by financing activities. 
The increase in the net cash provided by financing activities 
was primarily attributable to the receipts of $100.0 million 
upfront payment from Royalty Pharma upon execution of 
Royalty Purchase Agreement in March 2023, and a $6.8 million 
decrease in treasury stock purchase in 2023 as compared 
to 2022.

Net cash used in financing activities was $29.8 million for 
the year ended December 31, 2022, as compared to net 
cash provided by financing activities of $22.7 million for 
the year ended December 31, 2021, resulting in a decrease 
of $52.6 million in the net cash resulting from financing 
activities. The decrease in the net cash resulting from 
financing activities was primarily attributable to the fact that 
in the year ended December 31, 2021, there was an issuance 
of subsidiary preferred shares of $37.6 million while for the 
year ended December 31, 2022, there was no such issuance, 
and due to the treasury share purchases of $26.5 million 
for the year ended December 31, 2022 while there were 
no such purchases for the year ended December 31, 2021. 
This decrease was partially offset by the fact that during 
the year ended December 31, 2021, there were payments 
to settle stock based awards of $13.3 million, while for 
the year ended December 31, 2022, there were no such 
payments made.

Investments Held at Fair Value
Investments held at fair value increased by $65.9 million to $317.8 million as of December 31, 2023. As of December 31, 2023, 
Investments held at fair value consist primarily of our common share investment in Karuna, Vor and Akili (Akili was in the form 
of preferred shares until August 2022) and our preferred share investment in Sonde (from May 2022) and Vedanta (from March 
2023). The increase is primarily attributed to an increase of $73.5 million in the value of Karuna shares as well as the Group 
recognizing its investment in the convertible preferred shares of Vedanta in the amount of $20.5 million subsequent to Vedanta 
being deconsolidated from the Group’s financial statements, partially offset by decreases in fair value of various investments. 

Cash, Cash Equivalents, and Short-Term Investments
Consolidated cash, cash equivalents and short-term investments decreased by $23.0 million to $327.1 million as of December 31, 
2023. The decrease is primarily attributed to net cash used in operating activities of $105.9 million, purchase of treasury 
stock of $19.6 million, purchase of convertible note from associate of $16.9 million, and cash derecognized upon loss of 
control over Vedanta of $13.8 million, partially offset by proceeds of $33.3 million from sale of Karuna shares during the year 
ended December 31, 2023, and receipts of $100.0 million upfront payment from Royalty Pharma upon execution of Royalty 
Purchase Agreement in March 2023.

Non-Current Liabilities
Non-current liabilities increased by $126.2 million to $184.4 million as of December 31, 2023. The increase was driven by the 
Group receiving a $100.0 million non-refundable initial payment at the execution of the Royalty Purchase Agreement with 
Royalty Pharma, which is accounted for as a non-current sale of future royalties liability, as well as the accretion of non-cash 
interest expense on the sale of future royalties liability, and a $32.8 million increase in our deferred tax liabilities, partially offset 
by a $10.2 million decrease in long-term loan due to Vedanta being deconsolidated in 2023.

Trade and Other Payables
Trade and other payables decreased by $10.7 million to $44.1 million as of December 31, 2023. The decrease reflected primarily 
the deconsolidation of Vedanta and the timing of payments as of December 31, 2023.

Preferred Shares 
Preferred share liability in subsidiaries decreased by $27.2 million as of December 31, 2023. The decrease in the preferred 
share liability primarily relates to a decrease of $24.6 million due to the deconsolidation of Vedanta during the year 
ended December 31, 2023.

Financial Review continued

Quantitative and Qualitative Disclosures about Financial Risks
Interest Rate Sensitivity 
As of December 31, 2023, we had cash and cash equivalents 
of $191.1 million and short-term investments of $136.1 million, 
while we had PureTech Level cash, cash equivalents and 
short-term investments of $326.0 million. PureTech Level 
cash, cash equivalents and short-term investments is a non-
IFRS measure (for a definition of PureTech Level cash, cash 
equivalents and short-term investments and a reconciliation 
with the IFRS number, see the section Measuring Performance 
earlier in this Financial review). Our exposure to interest rate 
sensitivity is impacted by changes in the underlying U.K. and 
U.S. bank interest rates. We have not entered into investments 
for trading or speculative purposes. Due to the conservative 
nature of our investment portfolio, which is predicated on 
capital preservation and investments in short duration, high-
quality U.S. Treasury Bills and related money market accounts, 
we do not believe a change in interest rates would have a 
material effect on the fair market value of our portfolio, and 
therefore, we do not expect our operating results or cash flows 
to be significantly affected by changes in market interest rates. 

Foreign Currency Exchange Risk 
We maintain our consolidated financial statements in our 
functional currency, which is the U.S. dollar. Monetary 
assets and liabilities denominated in currencies other than 
the functional currency are translated into the functional 
currency at rates of exchange prevailing at the balance sheet 
dates. Non-monetary assets and liabilities denominated in 
foreign currencies are translated into the functional currency 
at the exchange rates prevailing at the date of the transaction. 
Exchange gains or losses arising from foreign currency 
transactions are included in the determination of net income 
(loss) for the respective periods. Such foreign currency gains or 
losses were not material for all reported periods.

Controlled Founded Entity Investments
We maintain investments in certain Controlled Founded 
Entities. Our investments in Controlled Founded Entities 
are eliminated as intercompany transactions upon financial 
consolidation. We are exposed to a preferred share liability 
owing to the terms of existing preferred shares and the 
ownership of Controlled Founded Entities preferred shares 
by third parties. The liability of preferred shares is maintained 
at fair value through profit and loss. We view our exposure 
to third-party preferred share liability as low as of December 
31, 2023 as the liability is not significant. Please refer to Note 
16. Subsidiary Preferred Shares to our Consolidated Financial 
Statements for further information regarding our exposure to 
Controlled Founded Entity investments. 

PureTech Health plc   Annual Report and Accounts 2023    79  

Deconsolidated Founded Entity Investments
We maintain certain debt or equity holdings in Founded 
Entities which have been deconsolidated. These holdings 
are deemed either as investments carried at fair value under 
IFRS 9 with changes in fair value recorded through profit and 
loss or as associates accounted for under IAS 28 using the 
equity method. Our exposure to investments held at fair value 
and investments in notes from associates was $317.8 million 
and $4.6 million, respectively, as of December 31, 2023, 
and we may or may not be able to realize the value in the 
future. Accordingly, we view the risk as high. Our exposure 
to investments in associates is limited to the carrying amount 
of the investment. We are not exposed to further contractual 
obligations or contingent liabilities beyond the value of 
initial investment. As of December 31, 2023, Sonde was the 
only associate, and the carrying amount of the investments 
in Sonde accounted for under the equity method was 
$3.2 million. Accordingly, we do not view this risk as high. 

Equity Price Risk 
As of December 31, 2023, we held 886,885 common shares 
of Karuna, 2,671,800 common shares of Vor, and 12,527,477 
common shares of Akili. The fair value of our investments in 
the common shares of Karuna, Vor and Akili was $280.7 million, 
$6.0 million, and $6.1 million, respectively.

The investments in Karuna, Vor and Akili are exposed to 
fluctuations in the market price of these common shares. The 
effect of a 10.0 percent adverse change in the market price 
of Karuna, Vor and Akili common shares as of December 31, 
2023, would cause a loss of $29.3 million to be recognized as 
a component of other income (expense) in our Consolidated 
Statement of Comprehensive Income/(Loss). However, we 
view exposure to equity price risk as low due to the definitive 
merger agreement Karuna entered into with Bristol Myers 
Squibb ("BMS”) in December 2023 under which Karuna 
common shares were acquired by BMS for $330 per share in 
March 2024. See Note 28. Subsequent Events. 

Liquidity Risk 
We do not believe we will encounter difficulty in meeting the 
obligations associated with our financial liabilities that are 
settled by delivering cash or another financial asset. While 
we believe our cash and cash equivalents and short-term 
investments do not contain excessive risk, we cannot provide 
absolute assurance that in the future, our investments will not 
be subject to adverse changes or decline in value based on 
market conditions. 

Governance80    PureTech Health plc   Annual Report and Accounts 2023

Financial Review continued

Credit Risk 
We maintain an investment portfolio in accordance with our 
investment policy. The primary objectives of our investment 
policy are to preserve principal, maintain proper liquidity 
and meet operating needs. Although our investments are 
subject to credit risk, our investment policy specifies credit 
quality standards for our investments and limits the amount 
of credit exposure from any single issue, issuer or type of 
investment. We do not own derivative financial instruments. 
Accordingly, we do not believe that there is any material 
market risk exposure with respect to derivative or other 
financial instruments. 

Credit risk is also the risk of financial loss if a customer 
or counterparty to a financial instrument fails to meet 
its contractual obligations. We are potentially subject 
to concentrations of credit risk in accounts receivable. 
Concentrations of credit risk with respect to receivables is 
owed to the limited number of companies comprising our 
receivable base. However, our exposure to credit losses is 
currently low due to relatively low receivable balance, a small 
number of counterparties and the high credit quality or healthy 
financial conditions of these counterparties. 

Foreign Private Issuer Status 
Owing to our U.S. listing on the Nasdaq Global Market, 
we report under the Securities Exchange Act of 1934, as 
amended, or the Exchange Act, as a non-U.S. company with 
foreign private issuer status. As long as we qualify as a foreign 
private issuer under the Exchange Act, we will be exempt from 
certain provisions of the Exchange Act that are applicable to 
U.S. domestic public companies, including: 

 — the sections of the Exchange Act regulating the solicitation 

of proxies, consents or authorizations in respect of a security 
registered under the Exchange Act; 

 — sections of the Exchange Act requiring insiders to file public 
reports of their stock ownership and trading activities and 
liability for insiders who profit from trades made in a short 
period of time; 

 — the rules under the Exchange Act requiring the filing with the 
SEC of quarterly reports on Form 10-Q containing unaudited 
financial and other specified information, or current reports 
on Form 8-K, upon the occurrence of specified significant 
events; and 

 — Regulation FD, which regulates selective disclosures of 

material information by issuers.

Chair’s overview
“We believe that good corporate 
governance is essential for building a 
successful and sustainable business.”

Dear Shareholder,

I am pleased to introduce our Corporate Governance Report. 
This Report sets out our governance framework and the work of 
the Board and its committees.

As a Board, we are responsible for ensuring there is an effective 
governance framework in place. This includes setting the 
Company’s strategic objectives, ensuring the right leadership 
and resources are in place to achieve these objectives, monitoring 
performance, ensuring that sufficient internal controls and 
protections are in place and reporting to shareholders. An 
effective governance framework is also designed to ensure 
accountability, fairness and transparency in the Company’s 
relationships with all of its stakeholders, whether shareholders, 
employees, partners, the government or the wider patient 
community. We believe that good corporate governance is 
essential for building a successful and sustainable business.

The Board is committed to the highest standards of corporate 
governance and undertakes to maintain a sound framework for 
our control and management. In this Report, we provide details of 
that framework.

The key constituents necessary to deliver a robust structure are in 
place and, accordingly, this report includes a description of how 
the Company has applied the principles and provisions of the 
Governance Code and how it intends to apply those principles 
in the future.

Since the Company’s 2023 Annual General Meeting, it has been 
my pleasure to act in the position of interim Chair, in addition to my 
role as the Senior Independent Director, to ensure continuity and 
the maintenance of strong governance practices at PureTech. As 
part of my expanded role, I have been working with my colleagues 
on the Nomination Committee and the rest of the Board to 
identify a suitable successor to our former Chair, Mr. Christopher 
Viehbacher. This process is ongoing as we work to identify a 
seasoned candidate with extensive experience in maximising 
shareholder value. 

The Nomination Committee, with assistance from the rest of 
the Board and the Company’s management, has also continued 
to explore potentially adding another non-executive director 
to strengthen the Board’s skillsets and reinforce the strong 
governance that has been a hallmark of the Company’s Board 
and broader operations. While there is not a firm timeline for 
the identification of a new Chair and potential additional non-
executive director, the Nomination Committee and the Company 
are conducting a thorough and efficient process to identify the 
best candidates. 

The Board looks forward to being able to discuss these matters 
with our shareholders in connection with our AGM or indeed at 
any other time during the year.

The Board

Roles and responsibilities of the Board
The Board is responsible to shareholders for our overall 
management as a whole. The main roles of the Board are:

 — creating value for shareholders;
 — providing business and scientific leadership;
 — approving our strategic objectives;
 — ensuring that the necessary financial and human resources are 

in place to meet strategic objectives;

 — overseeing our system of risk management; and
 — setting the values and standards for both our business conduct 

and governance matters.

The Directors are also responsible for ensuring that obligations 
to shareholders and other stakeholders are understood and met 
and that communication with shareholders is maintained. The 
responsibility of the Directors is collective, taking into account 
their respective roles as Executive Directors and Non-Executive 
Directors. All Directors are equally accountable to the Company’s 
shareholders for the proper stewardship of its affairs and our long-
term success.

The Board reviews strategic issues on a regular basis. During 
the past year the Board has played an active role on a variety of 
strategic initiatives of the Company. Members served as subject 
matter experts, advised on asset evaluation strategy and reviewed 
potential transactions. In addition, several members served on 
an independent transactions committee, led by the interim Chair. 
As a result, certain members have devoted substantial time and 
effort to the Company, above and beyond what would typically be 
expected of Non-Executive Directors.

The Board has also exercised control over our performance 
by agreeing on budgetary and operational targets and 
monitoring performance against those targets. The Board has 
overall responsibility for our system of internal controls and risk 
management. Any decisions made by the Board on policies and 
strategy to be adopted by us or changes to current policies and 
strategy are made following presentations by the Executive 
Director and other members of management, and only after a 
detailed process of review and challenge by the Board. Once 
made, the Executive Director and other members of management 
are fully empowered to implement those decisions.

Except for a formal schedule of matters which are reserved for 
decision and approval by the Board, the Board has delegated our 
day-to-day management to the Chief Executive Officer who is 
supported by other members of the senior management team. 
The schedule of matters reserved for Board decision and approval 
are those significant to us as a whole due to their strategic, 
financial or reputational implications.

The Company’s schedule of matters reserved for the Board 
includes the following matters:

 — approval and monitoring of our strategic aims and objectives;
 — approval of the annual operating and capital 

expenditure budget;

 — changes to our capital structure, the issue of any of our 

securities and material borrowings;

 — approval of the annual report and half-year results statement, 
accounting policies and practices or any matter having a 
material impact on our future financial performance;

 — ensuring a sound system of internal control and 

risk management;

 — approving Board appointments and removals, and approving 

policies relating to directors’ remuneration;

 — strategic acquisitions;
 — major disposals of our assets or subsidiaries;
 — approval of all circulars, prospectuses and other documents 

issued to shareholders governed by the Financial 
Conduct Authority’s (FCA) Listing Rules, Disclosure 
Guidance and Transparency Rules or the City Code on 
Takeovers and Mergers;

 — approval of terms of reference and membership of 

Board committees;

 — considering and, where appropriate, approving directors’ 

conflicts of interest; and

 — approval, subject to shareholder approval, of the appointment 

and remuneration of the auditors.

The schedule of matters reserved to the Board is available on 
request from the Company Secretary or within the Investors 
section of our website at www.puretechhealth.com.

The Board delegates specific responsibilities to certain 
committees that assist the Board in carrying out its functions 
and ensure independent oversight of internal control and risk 
management. The three principal Board committees (Audit, 
Remuneration and Nomination) play an essential role in 
supporting the Board in fulfilling its responsibilities and ensuring 
that we maintain the highest standards of corporate governance. 
Each committee has its own terms of reference which set out the 
specific matters for which delegated authority has been given 
by the Board.

The terms of reference for each of the committees are fully 
compliant with the provisions of the Governance Code. 
All of these are available on request from the Company 
Secretary or within the Investors section of our website at 
www.puretechhealth.com.

PureTech Health plc   Annual Report and Accounts 2023    87  

Board size and composition
As of December, 2023, there were seven Directors on the Board: 
the Non-Executive interim Chair, two Executive Directors and four 
Non-Executive Directors. Following the departure from the Board 
of Daphne Zohar on April, 2024 to become chief executive officer 
of PureTech founded entity, Seaport Therapeutics, Inc., there 
were six Directors on the Board: the Non-Executive interim Chair, 
one Executive Director and four Non-Executive Directors. The 
biographies of these Directors (including the former CEO and the 
former Chair) are provided on pages 82 to 85. Raju Kucherlapati, 
Ph.D., assumed the role of PureTech’s Senior Independent 
Director as well as the chair of its Nomination Committee, 
effective as of January 1, 2023, following the retirement of Dame 
Marjorie Scardino. Additionally, Dr. Kucherlapati assumed the role 
of interim Chair following the conclusion of the term of the former 
Chair Mr. Christopher Viehbacher on June 13, 2023. There were no 
other changes to the composition of the Board during 2023. Dr. 
Raju Kucherlapati will continue as interim Chair until a permanent 
Chair can be selected and appointed. Dr. Kucherlapati will also 
continue in his current role of Senior Independent director during 
this period. 

While the Company is conducting a search for a new Chair of the 
Board and considering adding an additional member, it does not 
anticipate that these activities will be completed by the time of 
the 2024 AGM. 

The Company’s policy relating to the terms of appointment 
and the remuneration of both Executive and Non-Executive 
Directors is detailed in the Directors’ Remuneration Report 
on pages 102 to 122.

The size and composition of the Board is regularly reviewed by 
the Nomination Committee to ensure there is an appropriate and 
diverse mix of skills and experience on the Board.

The Board may appoint any person to serve as a Director, either to 
fill a vacancy or as an addition to the existing Board. Any Director 
so appointed by the Board shall hold office only until the following 
AGM and then shall be eligible for election by the shareholders. In 
accordance with the Governance Code, all of the Directors will be 
offering themselves for election at the AGM to be held on June 13, 
2024, full details of which are set out in the notice of meeting 
accompanying this Annual Report.

Non-Executive Directors
The Company’s Non-Executive Directors are Dr. Raju Kucherlapati 
(interim Chair), Ms. Sharon Barber-Lui, Dr. John LaMattina, Dr. 
Robert Langer, and Ms. Kiran Mazumdar-Shaw. 

The Non-Executive Directors provide us with a wide range of skills 
and experience. Each Non-Executive Director has significant 
senior level experience as well as an extensive network in each 
of their own fields, an innovative mindset and independent 
judgement on issues of strategy, performance and risk, and 
is well placed to constructively challenge and scrutinize the 
performance of management. In addition, certain of our Non-
Executive Directors also serve as members of one or more boards 
of directors of our Founded Entities and are key drivers for our 
Internal Programs.

Senior Independent Director
The Company’s Senior Independent Director is Dr. Raju 
Kucherlapati. A key responsibility of the Senior Independent 
Director, following the appointment of a permanent Chair, is 
to be available to shareholders in the event that they may feel it 
inappropriate to relay views through the Chair or Chief Executive 
Officer. In addition, the Senior Independent Director is to serve 
as an intermediary between the rest of the Board and the Chair 
where necessary. Further, the Senior Independent Director will 
lead the Board in its deliberations on any matters on which the 
Chair is conflicted. For the period while Dr. Raju Kucherlapati 
serves as both interim Chair and Senior Independent Director, any 
other of the Non-Executive Directors is available to shareholders 
in the event that they may feel it inappropriate to relay views 
through the Chair or Chief Executive Officer. In addition, any other 
of the Non-Executive Directors may be elected by the Board to 
lead the Board in its deliberations on any matters on which Dr. Raju 
Kucherlapati is conflicted.

The roles of Chair and Chief Executive Officer
The Company’s interim Chair is Dr. Raju Kucherlapati. He has 
served as interim Chair since the 2023 AGM to fulfill the leadership 
requirements and governance obligations of the role following 
the resignation of the former Chair. The Nomination Committee 
is currently conducting a search to identify a new permanent 
Chair, but such person is not expected to be in place at the time of 
the 2024 AGM. Until such permanent replacement is appointed 
as Chair by the Board, Dr. Raju Kucherlapati is serving as interim 
Chair. There is and will remain a clear division of responsibilities 
between the Chair and the Chief Executive Officer. 

The Chair is responsible for the leadership and conduct of 
the Board and for ensuring effective communication with 
shareholders.

The Chair facilitates the full and effective contribution of Non-
Executive Directors at Board and Committee meetings, ensures 
that they are kept well informed and ensures a constructive 
relationship between the Executive Directors and Non-Executive 
Directors. The Chair also ensures that the Board committees carry 
out their duties, including reporting back to the Board either orally 
or in writing following their meetings at the next Board meeting.

The role of the Chief Executive Officer, Dr. Bharatt Chowrira, is to 
lead the execution of the Company’s strategy and the executive 
management of PureTech. She is responsible, among other 
things, for the development and implementation of strategy 
and processes which enable us to meet the requirements of 
shareholders, for delivering the operating plans and budgets for 
our businesses, for monitoring business performance against key 
performance indicators (KPIs) and reporting on these to the Board 
and for providing the appropriate environment to recruit, engage, 
retain and develop the high-quality personnel needed to deliver 
our strategy.

Governance88    PureTech Health plc   Annual Report and Accounts 2023

The Board continued

Independence
The Governance Code requires that at least 50 percent of the 
Board of a UK premium listed company, excluding the Chair, 
consists of Non-Executive Directors determined by the Board 
to be independent in character and judgement and free from 
relationships or circumstances which may affect, or could appear 
to affect, the Directors’ judgement. The Board regards Ms. 
Barber-Lui, Dr. Kucherlapati, Dr. LaMattina and Ms. Mazumdar-
Shaw as Independent Non-Executive Directors for the purposes 
of the Governance Code. In reaching this determination, the 
Board duly considered (i) their directorships and links with 
other Directors through their involvement in other subsidiary 
companies; (ii) their equity interests in PureTech and/or the 
Founded Entities, including equity grants of restricted stock 
units made to Non-Executive Directors by the Company under its 
Performance Share Plan; and (iii) in respect of Dr. LaMattina and 
Dr. Kucherlapati, the length of their tenures as Directors of the 
Company. The Board is satisfied that the judgement, experience 
and challenging approach adopted by each of these Directors 
should ensure that they each make a significant contribution to the 
work of the Board and its committees. Therefore, the Board has 
determined that Ms. Barber-Lui, Dr. Kucherlapati, Dr. LaMattina, 
and Ms. Mazumdar-Shaw are of independent character and 
judgement, notwithstanding the circumstances described at (i), 
(ii) and (iii) above. In addition, with respect to Dr. Kucherlapati, the 
Board has considered his role as interim Chair and determined 
that such additional responsibilities shall not impact his 
independence in light of the interim nature of the role and the 
search underway for a permanent Chair appointee.

The Nomination Committee, with assistance from the rest of the 
Board and the Company’s management, is focused on potentially 
adding an additional independent non-executive director in 
order to strengthen the Board’s skillsets and reinforce the strong 
governance that has been a hallmark of the Company’s Board 
and broader operations. The Nomination Committee and the 
Company intend to conduct a thorough and expeditious process 
to identify the best candidates. Progress updates will be provided 
in due course. 

Board support, indemnity and insurance
The Company Secretary, Mr. Charles Sherwood, is responsible to 
the Board for ensuring Board procedures are followed, applicable 
rules and regulations are complied with and that the Board is 
advised on governance and relevant regulatory matters. All 
Directors have access to the impartial advice and services of the 
Company Secretary.

There is also an agreed procedure for Directors to take 
independent professional advice at the Company’s expense. 
In accordance with the Company’s Articles of Association and a 
contractual Deed of Indemnity, the Directors have been granted 
an indemnity issued by the Company to the extent permitted 
by law in respect of liabilities incurred to third parties as a result 
of their office. The indemnity would not provide any coverage 
where a Director is proved to have acted fraudulently or with 
wilful misconduct. The Company has also arranged appropriate 
insurance cover in respect of legal action against its Directors 
and officers.

Board meetings and decisions
The Board meets regularly during the year, as well as on an ad hoc 
basis as required by business need. The Board had 8 scheduled 
meetings in 2023, and details on attendance are set forth in the 
table below:

* Mr. Viehbacher retired from the Company’s Board in June 2023.
While each current director was able to attend the vast majority 
of meetings in 2023, in the event of any unavoidable absence, the 
impacted Director would review with management the topics and 
materials to be discussed at the meeting, and provide appropriate 
feedback to be conveyed at such meeting, as was the case with 
respect to the meetings any director was unable to attend. Ms. 
Zohar did not attend certain meetings where she recused herself 
in light of the topics to be discussed. 

The Board also acted by unanimous written consent five times 
in 2023. On occasion it was more expedient for the Board to 
approve matters, especially administrative matters, by unanimous 
written consent rather than to convene a meeting for the purpose. 
Directors were, however, provided with an opportunity to discuss 
any concerns they had with the written resolution before its issue 
for signature. 

At each quarterly meeting of the Board, there was a closed session 
held in which only the interim Chair and the other Non-Executive 
Directors participated. In certain meetings held to discuss a 
specific topic or topics, a closed session was not held due to 
limited time allocated for such meeting or the nature of the topic 
being considered.

The schedule of Board and Committee meetings each year is, so 
far as is possible, determined before the commencement of that 
year and all Directors or, if applicable, all Committee members, 
are expected to attend each meeting.

Supplementary meetings of the Board and/or the Committees 
are held as and when necessary. Each member of the Board 
receives in advance of each scheduled meeting detailed Board 
packages, which include an agenda based upon matters to 
be addressed and appropriate presentation and background 
materials. If a Director is unable to attend a meeting due to 

GovernanceThe Board continued

PureTech Health plc   Annual Report and Accounts 2023    89  

exceptional circumstances, he or she will nonetheless receive 
the meeting materials and discuss the materials with the Chief 
Executive Officer.

The Chair, Chief Executive Officer and senior management 
team work together to ensure that the Directors receive relevant 
information to enable them to discharge their duties and that 
such information is accurate, timely and clear. This information 
includes quarterly management accounts containing analysis 
of performance against budget as well as a summary of the 
operational performance of each of our businesses against its 
goals. Additional information is provided as appropriate for the 
topics being addressed at the meeting. At each meeting, the 
Board receives presentations from the Chief Executive Officer 
and, by invitation, other members of senior management as 
required. This ensures that all Directors are in a position to 
effectively monitor our overall performance, and to contribute to 
the development and implementation of its strategy.

Company Board meetings are held either in our offices in Boston, 
Massachusetts, U.S., or by videoconference. This practice began 
during the onset of the COVID-19 pandemic for the safety of the 
Board and has continued in recent years. The venue of Board 
meetings varies depending on the schedules and health of our 
directors. The Board endeavours to hold at least two in-person 
meetings during the year, as they give members of the Company’s 
senior management team, as well as the senior management of 
the Founded Entities, the opportunity to formally present to the 
Board on new technology development and business strategies. 

Certain Directors also serve on the boards of directors of our 
Founded Entities. These Founded Entity boards of directors meet 
regularly during the year, as well as on an ad hoc basis as required 
by business need. This service enables the Directors to have deep 
understanding of the businesses and contribute significantly to 
the strategy and oversight of these businesses.

Directors’ conflicts of interest
Each Director has a statutory duty under the Companies Act 2006 
(the CA 2006) to avoid a situation in which he or she has or can have 
a direct or indirect interest that conflicts or may potentially conflict 
with the interests of the Company. This duty is in addition to the 
continuing duty that a Director owes to the Company to disclose 
to the Board any transaction or arrangement under consideration 
by the Company in which he or she is interested. The Company’s 
Articles of Association permit the Board to authorize conflicts 
or potential conflicts of interest. The Board has established 
procedures for managing and, where appropriate, authorizing any 
such conflicts or potential conflicts of interest. In deciding whether 
to authorize any conflict, the Directors must have regard to their 
general duties under the CA 2006 and their overriding obligation 
to act in a way they consider, in good faith, will be most likely to 
promote the Company’s success. In addition, the Directors are 
able to impose limits or conditions when giving authorization 
to a conflict or potential conflict of interest if they think this is 
appropriate. The authorization of any conflict matter, and the 
terms of any authorization, may be reviewed by the Board at any 
time. The Board believes that the procedures established to deal 
with conflicts of interest are operating effectively.

Induction, awareness and development
In preparation for the Company’s initial public offering (IPO), 
and upon joining the Board subsequent to the IPO, Directors 
received an induction briefing from the Company’s legal advisors 
on their duties and responsibilities as Directors of a publicly 
quoted company. The Directors also received presentations from 
the Company’s corporate brokers prior to the IPO. In addition, 
in order to ensure that the Directors continue to further their 
understanding of the challenges facing our Founded Entities 
and Internal Programs, the Board periodically receives the 
presentations and reports covering the business and operations 
of each of our Founded Entities as well as its Internal Programs.

We have put in place a comprehensive induction plan for any 
new Directors. This program will be tailored to the needs of each 
individual Director and agreed with him or her so that he or she 
can gain a better understanding of us and our businesses. In 
addition, the Company facilitates sessions as appropriate with our 
advisors, as well as appropriate governance specialists, to ensure 
that any new Directors are fully aware of, and understand, their 
responsibilities and obligations of a publicly quoted company and 
of the governance framework within which they must operate. 

Board effectiveness and performance evaluation
The Board periodically reviews its effectiveness and performance. 
The Board seeks the assistance of an independent third-party 
provider at least once every three years in its evaluation in 
compliance with the Governance Code, and will otherwise carry 
out an internally facilitated Board evaluation led by the Senior 
Independent Director, assisted by the Company Secretary, 
covering the effectiveness of the Board as a whole, its individual 
Directors and its Committees. For 2023, internal evaluations of 
the Board demonstrated that the Board and its Committees fulfil 
their responsibilities, operate effectively and demonstrate a clear 
structure and division of responsibilities between the Board and 
its Committees. The increased quality of Board materials and 
presentations and advances in the process for evaluating strategic 
transactions were favourably viewed. The Board will continue to 
perform internal evaluations to ensure the effectiveness of the 
Board and ensure alignment with the interests of stakeholders.

In addition to the above, the Non-Executive Directors, led by the 
Senior Independent Director when that person is not also serving 
as interim Chair, will periodically appraise the permanent Chair’s 
performance, following which the Senior Independent Director 
will provide any feedback to the Chair. For the period while the 
Senior Independent Director also serves as interim Chair, the 
appraisal of the Interim Chair’s performance will be led by the 
Non-Executive Directors acting together. The performance of 
each of the Directors on the Board and the performance of the 
committees of the Board will be reviewed by the Chair as deemed 
necessary. The performance of Executive Directors will be 
reviewed by the Board on an ongoing basis, as deemed necessary, 
in the absence of the Executive Director under review.

Committees of the Board
The Board has three principal committees: the Nomination 
Committee, the Audit Committee and the Remuneration 
Committee. The composition of the three principal committees

records are maintained and transactions are recorded accurately 
and fairly to permit the preparation of financial statements in 
accordance with IFRS. The Board approves the annual operating 
budgets and regularly receives details of actual performance 
measured against the budget.

Principal risks and uncertainties
Our operations and the implementation of our objectives and 
strategy are subject to a number of key risks and uncertainties. 
Principal and emerging risks are formally reviewed by the Board 
at least annually and appropriate procedures are put in place to 
monitor and, to the extent possible, mitigate these risks.

A summary of the key risks affecting us and the steps taken 
to manage these risks are set out on pages 60 to 64 and in the 
Additional Information section from pages 186 to 223.

Political expenditure
It is the Board’s policy not to incur political expenditure or 
otherwise make cash contributions to political parties and it has 
no intention of changing that policy.

2024 Annual General Meeting
The Notice of the AGM, which will be held at 4:00 pm BST (11:00 
am EDT) on June 13, 2024 at the offices of FTI Consulting at 200 
Aldersgate, 200 Aldersgate Street, London EC1A 4HD, is enclosed 
with this report. Details of the resolutions and the explanatory 
notes thereto are included with the Notice. To ensure compliance 
with the Governance Code, the Board proposes separate 
resolutions for each issue and proxy forms allow shareholders 
who are unable to attend the AGM to vote for or against or to 
withhold their vote on each resolution. In addition, to encourage 
shareholders to participate in the AGM process, the Company 
proposes to offer electronic proxy voting through the Registrar’s 
website and through the CREST service. The results of all proxy 
voting will be published on our website after the AGM. 

Our website at www.puretechhealth.com is the primary source 
of information on us. The website includes an overview of our 
activities, details of our businesses, and details of all of our recent 
announcements.

Internal Control
The Board fully recognizes the importance of the guidance 
contained in the Guidance on Risk Management, Internal Control 
and Related Financial and Business Reporting. Our internal 
controls were in place during the whole of 2023 and we are 
satisfied that we have adequate controls and that our internal 
control over financial reporting was effective for the year ended 
December 31, 2023. 

The Board is responsible for establishing and monitoring internal 
control systems and for reviewing the effectiveness of these 
systems. The Board views the effective operation of a rigorous 
system of internal control as critical to our success; however, it 
recognizes that such systems are designed to manage rather than 
eliminate risk of failure and can provide only reasonable and not 
absolute assurance against material misstatement or loss. The key 
elements of our internal control system, all of which have been in 
place during the financial year and up to the date these financial 
statements were approved, are as follows:

Control environment and procedures 
We have a clear organizational structure with defined 
responsibilities and accountabilities. It adopts the highest values 
surrounding quality, integrity and ethics, and these values are 
communicated clearly throughout the whole organization. 
Detailed written policies and procedures have been established 
covering key operating and compliance risk areas. These policies 
and procedures are reviewed and the effectiveness of the systems 
of internal control is assessed periodically by the Board.

Identification and evaluation of risks
The Board actively identifies and evaluates the risks inherent in the 
business and ensures that appropriate controls and procedures 
are in place to manage these risks. The Board obtains an update 
regarding our Internal Programs and all Founded Entities on a 
regular basis, and reviews our performance and the performance 
of our Internal Programs and Founded Entities on a quarterly 
basis. However, the performance and structuring of business units 
may be reviewed more frequently if deemed appropriate.

The key risks and uncertainties we face, as well as the relevant 
mitigations, are set out on pages 60 to 64 and in the Additional 
Information section from pages 186 to 223.

Information and financial reporting systems
We evaluate and manage significant risks associated with the 
process for preparing consolidated accounts by having in place 
systems and internal controls that ensure adequate accounting

Relations with Stakeholders 
– Section 172 Statement

The Board recognizes its duties under Section 172 of the Companies Act 2006 and continuously has regard to how the Company’s 
activities and decisions will impact investors, employees, those with whom it has a business relationship, the community and 
environment and its reputation for high standards of business conduct. In weighing all of the relevant factors, the Board, acting in good 
faith and fairly between members, makes decisions and takes actions that it considers will best lead to the long- term success of the 
Company. In accordance with Section 172, it is the responsibility of the Board as a whole to ensure that a satisfactory dialogue takes 
place and that the Board considers the potential impact on the Company’s key stakeholders when making decisions.

The Board is committed to understanding and engaging with shareholders and other key stakeholder groups of the Company in order 
to maximize value and promote long-term Company success in line with our strategic objectives, as well as to promote and ensure 
fairness between our stakeholders. The Board believes that appropriate steps and considerations have been taken during the year so 
that each Director has an understanding of the various key stakeholders of the Company. The Board recognizes its responsibility to 
contemplate all such stakeholder needs and concerns as part of its discussions, decision-making, and in the course of taking actions and 
will continue to make stakeholder engagement a top priority in the coming years.

During the year, the Board assessed its current activities between the Board and its stakeholders, which demonstrated that the Board 
actively engages with its stakeholders and takes their various objectives into consideration when making decisions.

Stakeholder

How we engage

Key matters identified

Investors

 – Our shareholders are the owners and 
investors in our business. We make 
significant efforts to engage with 
our shareholders and understand 
their objectives. We engage with our 
shareholders through a number of 
mechanisms to ensure that shareholder 
views are brought into the boardroom and 
considered in our decision-making. 

 – The Board’s primary shareholder contact 

is through the Chief Executive Officer. The 
Chair, the Senior Independent Director 
and other Directors, as appropriate, 
make themselves available for contact 
with major shareholders and other 
stakeholders in order to understand their 
issues and concerns.

 – Stakeholder engagement will often take 
place by the Executive Directors and 
senior management through investor 
meetings and investor roadshows, including 
participation at healthcare conferences 
and participating in fireside chats at those 
events, with the Board receiving regular 
updates by way of analysis reports on 
stakeholder views.

 – Meetings were held throughout the year with 
institutional shareholders. Key shareholder 
publications including the annual report, the 
full year and half year results announcements 
and press releases and the information for 
investors are available on the Company’s 
website: www.puretechhealth.com. 

 – Our Board keeps its Strategy and Business Model 
under regular review. During the past year, the 
Board has engaged to carefully consider its 
strategy for future growth and development, 
in particular devoting attention to the future 
prospects of its business model and its listing 
venues and the risks and opportunities this would 
give to the Company’s stakeholders.

 – The company carefully manages its expenditure 
and anticipates future capital needs through 
careful capital management and capital 
allocation to its Internal Programs and clinical 
trials as well as opportunities to secure financing 
from third parties, for example we monetized 
PureTech’s royalty in Karuna Therapeutics’ 
KarXT for up to $500 million, with $100 million 
in cash paid up front. Our Board also carefully 
considers opportunities for disposal of shares in 
our Founded Entities, which have generated over 
$815 million in non-dilutive proceeds to advance 
our pipeline and growth since 2020. 

 – The Board seeks to ensure appropriate board 
structure and the Nomination Committee 
continues to actively evaluate seasoned 
candidates with extensive experience suitable for 
a Company of PureTech’s size.

 – The Board recognizes the importance of Diversity, 
Equity and Inclusion and is delighted to have a 
diverse group of leaders at both the Board and 
Management levels.

How we engage

Key matters identified

Our People

 – Our employees are crucial to the success of 
our business and many key decisions made 
by our Board have an impact on them. It 
is important to understand the employee 
perspective and ensure that we maintain 
an engaged workforce, as we believe that 
this will lead to better business results. We 
engage with our employees in various ways 
to ensure that their voice is heard in the 
management of our business including:

 – The conduct of regular town hall 

meetings, email briefings to employees 
on key events as well as communication 
through the company intranet site and an 
engagement survey

 – The implementation of regular appraisals 
and personal development programs

Community 
& 
Environment

 – We are committed to supporting the 
communities in which we operate and 
the wider public. To that end, we have 
developed various mechanisms for 
engagement including: 

 – Internships/partnerships with local 

universities and programs

 – Charitable giving
 – Building Certifications
 – Therapeutic Focus

 – The Board recognizes the importance of an 

incentivized and engaged workforce, especially 
in the highly competitive biotechnology cluster 
of the greater Boston area. While the Board 
recognized the three methods suggested in 
the Code for workforce engagement, the Board 
opted for a more informal approach given the 
Company’s number of employees. The Board 
is responsive to the views of employees, and 
regularly seeks feedback from the Executive 
Directors on the overall culture of the Company 
which is aligned to the purpose, values and 
strategy of the organization. Executive Directors 
provide insights based on the feedback from 
routine employee engagement, such as through 
surveys and Town Hall Meetings. 

 – The Board aims to attract and retain employees. 

This is attained through a combination of 
competitive remuneration and benefit packages 
and an established personal management 
and development program. This program is 
implemented with a view to development of the 
individual in an inclusive environment where 
employees from diverse backgrounds can thrive. 

 – We are proud to be a company dedicated to 

giving life to new classes of medicine to improve 
the lives of patients with devastating diseases and 
believe we have established a business where our 
employees are proud to work. 

 – We are committed to improving our practices to 
ensure our business operates on a sustainable 
basis. In particular, we have created an ESG 
committee chaired by one of our Non-Executive 
Directors to guide our sustainability initiatives. 
Our business operates with low carbon emissions, 
and we are committed to delivering long-term 
environmental sustainability.

 – We partner with local universities and programs 

to offer paid internship and externship 
programs, generally within technical fields in our 
development organization.

 – The company engages with local community 

and supports charitable causes. In particular, in 
2023, PureTech made charitable contributions to 
the Pulmonary Fibrosis Foundation, School on 
Wheels and The Greater Boston Food Bank. 

Suppliers/
Business 
Partners

 – Our business model creates value through 

 – We aim to build clear and reliable supply 

partnerships and relationships with various key 
collaborators, and we continually evaluate how 
to strengthen relationships and arrangements 
with these institutions and individuals. Our 
engagement in 2023 included:

 – Quality updates and quality audits
 – Meetings with key surgeons to 

understand/identify potential indications 
and applications for therapeutics
 – Partnerships – BeiGene and Eli Lilly

arrangements with our contract manufacturers 
for clinical product supply, in particular with an 
emphasis on quality, especially in relation to a 
clinical environment. 

 – We seek partnerships with other life sciences 
organizations to secure non-dilutive funding, 
access to development opportunities and access 
to materials for our clinical trials.

that attaches to them in defending proceedings brought against 
them, to the extent permitted by the Companies Act. In addition, 
Directors and officers of the Company and its Founded Entities 
have been and continue to be covered by Directors’ and officers’ 
liability insurance.

See further description of indemnity and insurance on page 88.

Political donations
No political contributions/donations for political purposes 
were made by the Company or any of our affiliate companies to 
any political party, politician, elected official or candidate for 
public office during the financial year ended December 31, 2023 
(2022: nil).

Significant agreements
There are no agreements between the Company or any of our 
affiliate companies and any of its employees or any Director which 
provide for compensation to be paid to an employee or a Director 
for loss of office as a consequence of a takeover of the Company.

Compliance with the UK Corporate Governance Code
The Directors are committed to a high standard of corporate 
governance and compliance with the best practice of the UK 
Corporate Governance Code (Governance Code) published 
in July 2018. The Governance Code is available at the Financial 
Reporting Council website at www.frc.org.uk.

The Directors consider that the Company has, throughout the 
year ended December 31, 2023, applied the main principles and 
complied with the provisions set out in the Governance Code with 
the following exceptions:

 — Dr. Raju Kucherlapati, the interim Chair, is also Chair of 
the Nomination Committee when it is dealing with the 
appointment of a successor, which is not aligned with provision 
17 of the Governance Code. In making the determination 
for maintaining Dr. Kucherlapati as Chair of the Nomination 
Committee the Board duly considered (i) the interim nature 
of the role and the search underway for a permanent Chair 
appointee (ii) his professional background (iii) his tenure on the 
Board and experience. The Board deemed this to be relevant 
experience making his role as Chair of Committee in the 
best interest of the Company’s shareholders. The Board has 
acknowledged Dr. Kucherlapati’s exemplary leadership during 
a busy and transformative period for the Company. However, 
the Directors are also cognizant of the extended tenure of 
Dr. Kucherlapati’s interim role and are taking affirmative steps 
to appoint a permanent Chair. These affirmative steps include 
both interviewing external potential candidates for the role 
as well as evaluating the skillsets and leadership qualities of 
its current members. If an external candidate is chosen as 
permanent Chair, Dr. Kucherlapati is expected to remain a key 
member of the Company’s Board. 

 — Mr. Christopher Viehbacher, the former Chair, served on 

the Audit Committee during the year, which is not aligned 
with provision 24 of the Governance Code. In making the 
determination for maintaining Mr. Viehbacher as a member 
of the Audit Committee the Board duly considered (i) his 
experience as a Chartered Accountant and numerous senior 
executive positions in his career (ii) his prior service as chair of 
the Committee and (iii) his departure from the Committee and 
the Board following the 2023 AGM. The Board deemed this to 
be recent and relevant financial experience, qualifying him to 
serve on the Committee.

February 7, 2024, the Company repurchased an aggregate of 
20,182,863 ordinary shares under the Share Buyback Programme,

the 2023 AGM, and the authority from the 2023 AGM expires

bribery and corruption policy which prohibits our employees 
from engaging in bribery or any other form of corruption. In 
addition, we have a whistleblowing policy under which staff 
are encouraged to report to the Chief Executive Officer or the 
President any alleged wrongdoing, breach of a legal obligation 
or improper conduct by or on the part of us or any of our officers, 
Directors, employees, consultants or advisors. In the event of a 
communication to the Executive Directors or others, including via 
the Company’s Whistleblower hotline, pursuant to these policies, 
this information will be shared with the Audit Committee who will 
evaluate the claims and in turn report to the rest of the Board. 

Transition of auditor
During 2023, the Audit Committee oversaw the handover and 
induction arrangements to ensure a smooth transition for our 
new auditors. Last year, following a tender offer process, the 
Audit Committee recommended to the Board the appointment 
of PricewaterhouseCoopers LLP UK (“PwC”) as the preferred 
new auditor, replacing KPMG LLP who has served as our auditor 
since 2015. Based on this recommendation, the Board proposed 
that PwC be appointed as external auditor of Company, which 
received shareholder approval at the 2023 AGM Audit Committee, 
with 99.75% of votes cast in favour of the appointment.

Disclosure of information to auditor
The Directors who held office at the date of approval of this 
Directors’ report confirm that:

GovernanceDirectors’ Report for the year ended December 31, 2023 continued

PureTech Health plc   Annual Report and Accounts 2023    97  

 — so far as the Director is aware, there is no relevant audit 

information of which the Company’s Auditor is unaware; and
 — the Director has taken all steps that he/she ought to have taken 
as a Director in order to make himself/herself aware of any 
relevant audit information and to establish that the Company’s 
Auditor is aware of that information.

This confirmation is given and should be interpreted in 
accordance with the provisions of Section 418 of the CA 2006.

Statement of Directors’ responsibilities in respect of the 
Annual Report and the financial statements
The Directors are responsible for preparing the Annual Report 
and the Group and parent Company financial statements in 
accordance with applicable law and regulations. 

Company law requires the directors to prepare Group and 
parent Company financial statements for each financial year. 
Under that law they are required to prepare the Group financial 
statements in accordance with UK-adopted international 
accounting standards and applicable law and have elected to 
prepare the parent Company financial statements on the same 
basis. In addition, the Group financial statements are required 
under the UK Disclosure Guidance and Transparency Rules to 
be prepared in accordance with the UK-adopted international 
accounting standards.

Under Company law the Directors must not approve the financial 
statements unless they are satisfied that they give a true and fair 
view of the state of affairs of the Group and parent Company and 
of the Group’s profit or loss for that period. In preparing each 
of the Group and parent Company financial statements, the 
directors are required to: 

 — select suitable accounting policies and then apply them 

consistently; 

 — make judgements and estimates that are reasonable, relevant 

and reliable; 

 — state whether they have been prepared in accordance with the 

UK-adopted international accounting standards;

 — assess the Group and parent Company’s ability to continue as 
a going concern, disclosing, as applicable, matters related to 
going concern; and 

 — use the going concern basis of accounting unless they either 
intend to liquidate the Group or the parent Company or to 
cease operations, or have no realistic alternative but to do so. 

The Directors are responsible for keeping adequate accounting 
records that are sufficient to show and explain the parent 
Company’s transactions and disclose with reasonable accuracy 
at any time the financial position of the parent Company and 
enable them to ensure that its financial statements comply with 
the Companies Act 2006. They are responsible for such internal 
control as they determine is necessary to enable the preparation 
of financial statements that are free from material misstatement, 
whether due to fraud or error, and have general responsibility for 
taking such steps as are reasonably open to them to safeguard 
the assets of the Group and to prevent and detect fraud and 
other irregularities.

Under applicable law and regulations, the Directors are also 
responsible for preparing a Strategic Report, Directors’ Report, 
Directors’ Remuneration Report and Corporate Governance 
Statement that complies with that law and those regulations. 

The Directors are responsible for the maintenance and 
integrity of the corporate and financial information included 
on the Company’s website. Legislation in the UK governing the 
preparation and dissemination of financial statements may differ 
from legislation in other jurisdictions. 

Responsibility statement of the Directors in respect of the 
annual financial report
We confirm that to the best of our knowledge: 

 — the financial statements, prepared in accordance with the 
applicable set of accounting standards, give a true and fair 
view of the assets, liabilities, financial position and profit or 
loss of the Company and the undertakings included in the 
consolidation taken as a whole; and 

 — the strategic report includes a fair review of the development 

and performance of the business and the position of the issuer 
and the undertakings included in the consolidation taken as 
a whole, together with a description of the principal risks and 
uncertainties that they face. 

We consider the annual report and accounts, taken as a whole, is 
fair, balanced and understandable and provides the information 
necessary for shareholders to assess the Group’s position and 
performance, business model and strategy.

Chair, Nomination Committee

might affect, or appear to affect, the Directors’ judgement in 
their service on the Nomination Committee. While the Board 
has not deemed Dr. Langer independent for the purposes of 
overall Board composition, he is independent in the context 
of his service on the Nomination Committee. The Board duly 
considered (i) his involvement in other Founded Entities and (ii) the 
exceptional circumstance that Dr. Langer is a founding Director 
of the Company. The Board further regards Dr. Kucherlapati as 
independent on the basis of the Governance Code criteria despite 
also serving as interim Chair of the Board since June 2023 in light 
of the criteria listed above and the fact that Dr. Kucherlapati’s 
appointment as Chair of the Board is temporary in nature. 

The Nomination Committee meets as required to initiate the 
selection process of, and make recommendations to, the Board 
with regard to the appointment of new Directors. During 2023, 
the Nomination Committee met one time to review the structure, 
size and composition of the Board in light of the requirements of 
the Governance Code. Dr. Kucherlapati, Ms. Mazumdar-Shaw and 
Dr. Langer participated in the meeting. Mr. Viehbacher, the Chief 
Executive Officer and the President were invited to and attended 
the meeting.

In light of the retirement of Dame Scardino at the end of 2022 
and departure of Mr. Viehbacher following the Company’s 2023 
AGM, the committee undertook a search to identify a new Board 
Chair and Director. This thorough search is aimed at replacing 
these outgoing Directors with individuals of the same stature 
while focusing on the key skill sets needed to complement the 
current Board and guide the Company in its continued evolution. 
The Company will provide updates in due course but does not 
currently expect that such new Directors will be in place at the time 
of the 2024 AGM.

Diversity policy
Diversity within the Company’s Board and the Management 
Team is essential in maximizing its effectiveness, as it enriches 
debates, business planning and problem- solving. The Company 
approaches diversity in its widest sense so as to recruit and 
develop the best talent available, based on merit and assessed 
against objective criteria of skills, knowledge, independence 
and experience as well as other criteria such as gender, age and 
ethnicity. This approach is also applied to ensuring diversity 
within the Board and the Remuneration, Audit and Nomination 
committees. The Company will adhere to a strategy of recruiting 
individuals who meet these criteria as it searches for additional 
independent Non-Executive Directors to the Board, as discussed 
below. The Committee’s primary objective is to ensure that the 
Company maintains the strongest possible leadership across both 
the Board and the Management Team..

Information regarding the Company’s diversity efforts can be 
found in the ESG Report on pages 24 to 45.

Board and Committee evaluation
Information regarding the evaluation of the Board and its 
Committees can be found on page 90.

Committee responsibilities
The Nomination Committee assists the Board in discharging its 
responsibilities relating to the composition and make-up of the 
Board and any Committees of the Board. It is also responsible 
for periodically reviewing the Board’s structure and identifying 
potential candidates to be appointed as Directors or Committee 
members as the need may arise. The Nomination Committee is 
responsible for evaluating the balance of skills, knowledge and 
experience and the size, structure and composition of the Board 
and Committees of the Board, retirements and appointments 
of additional and replacement Directors and Committee 
members, and makes appropriate recommendations to the 
Board on such matters. A full copy of the Committee’s Terms of 
Reference is available on request from the Company Secretary 
and within the Investor’s section on Company’s website at 
www.puretechhealth.com.

Committee membership
The Nomination Committee consisted of Dr. Raju Kucherlapati, 
who served as the committee’s Chair, Dr. Robert Langer, and 
Ms. Kiran Mazumdar-Shaw during 2023. The biographies of the 
Nomination Committee members can be found on pages 82 to 83.

The Governance Code requires that a majority of the members 
of a nomination committee should be independent Non-
Executive Directors.

In making their determination for the year 2023, the Board 
regarded Dr. Raju Kucherlapati, Dr. Langer and Ms. Mazumdar-
Shaw as meeting the independence criteria set out in the 
Governance Code as it is applied to their service on the 
Nomination Committee. In reaching this determination, the 
Board duly considered (i) their directorships and links with other 
Directors through their involvement in other Founded Entities; 
(ii) their equity interests in PureTech Health and/or the Founded 
EntitiesThe Board also duly considered the extent to which these 
matters may impact their service on the Nomination Committee. 
After such consideration, the Board has determined Dr. Langer 
and Ms. Mazumdar-Shaw to be independent in character and 
judgement and free from relationships or circumstances which

Chair, Audit Committee

in making the independence determination for the interim Chair, 
Dr. Kucherlapati, the Board considered his (i) his prior service 
on the Board (ii) relevant leadership positions within the sector 
and (iii) the interim nature of his role as interim Chair. The Board 
deemed this to be recent and relevant financial experience, 
qualifying both Mr. Viehbacher and Dr. Kucherlapati to serve 
on the Committee.

Ms. Barber-Lui has served as Chair of the Committee since 
April 26, 2022. Ms. Barber-Lui has experience as a Chartered 
Accountant and has held numerous senior executive positions in 
her career. The Board has deemed this to be recent and relevant 
financial experience, qualifying her to be Chair of the Committee. 
Ms. Barber-Lui has accounting experience, is currently the Chief 
Financial Officer and Senior Vice President, North America at Teva 
Pharmaceutical Industries Ltd., a publicly-traded Israeli company 
(NYSE and TASE: TEVA), and has held a number of senior finance 
and executive leadership positions in her career. The Board 
has deemed this to be recent and relevant financial experience 
qualifying her to be Chair of the Committee. 

Both Dr. Kucherlapati and Dr. LaMattina have also been deemed 
to have recent and relevant financial experience qualifying them 
to serve on the Committee. The Board based this determination 
based on (i) their numerous senior leadership positions and (ii) 
their competence in the sector in which the company operates. 
For Dr. Raju Kucherlapati and Dr. John LaMattina The biographies 
of the Committee members can be found on pages 82 to 83. 

The Committee met six times during the year, with Ms. Barber-Lui 
and Dr. Kucherlapati each attending all six meetings, 
Mr. Viehbacher attending three of four meetings prior to his 
departure from the Committee and Dr. LaMattina attending two 
meetings after replacing Mr. Viehbacher on the Committee. In 
2023, the Chief Executive Officer and President were invited to 
and attended all of the meetings, the prior Auditor was invited to 
and attended two of the meetings and the current Auditor was 
invited to and attended three of the meetings. When appropriate, 
the Committee met with the Auditor without any members of the 
executive management team being present.

Activities during the year
During the year, the Audit Committee oversaw the handover 
and induction arrangements to ensure a smooth transition for 
our new auditors. Last year, following a tender offer process, the 
Audit Committee recommended to the Board the appointment 
of PricewaterhouseCoopers LLP UK (“PwC”) as the preferred new 
auditor, replacing KPMG LLP who had served as our auditor since 
2015. Based on this recommendation, the Board proposed that 
PwC be appointed as external auditor of the Company, which 
received shareholder approval at the 2023 AGM Audit Committee, 
with 99.75% of votes cast in favour of the appointment. 

The Committee also undertook the normal recurring items, the 
most important of which are noted below. 

Committee responsibilities
The Audit Committee monitors the integrity of our financial 
statements and reviews all proposed annual and half-yearly results 
announcements to be made by us with consideration being 
given to any significant financial reporting judgements contained 
in them. The Committee also advises the Board on whether it 
believes the annual report and accounts, taken as a whole, are 
fair, balanced and understandable and provide the information 
necessary for shareholders to assess the Company’s position and 
performance, business model and strategy. The Committee also 
considers internal controls and has complied with the provisions of 
the Competition and Markets Authority Order. Additionally we are 
in compliance with legal requirements, including the provisions of 
the, FCA’s Listing Rules, Disclosure Guidance and Transparency 
Rules, and reviews any recommendations from the Group’s 
Auditor regarding improvements to internal controls and the 
adequacy of resources within our finance function. A full copy of 
the Committee’s Terms of Reference is available on request from 
the Company Secretary and within the Investor’s section on the 
Company’s website at www.puretechhealth.com.

Committee membership
The Committee consists of three independent Non-Executive 
Directors, Ms. Sharon Barber-Lui, Dr. Raju Kucherlapati and 
Dr. John LaMattina. Dr. LaMattina replaced Mr. Christopher 
Viehbacher following his departure from the Committee due 
to his retirement from the Board on June 13, 2023. 

The Governance Code requires that the audit committee be 
comprised of independent Non-Executive Directors, with the 
chair of the Board refraining from serving on the Committee. 
In making the determination for maintaining Mr. Viehbacher as 
a member of the Audit Committee the Board duly considered 
(i) his experience as a Chartered Accountant and numerous 
senior executive positions in his career (ii) his prior service as 
chair of the Committee and (iii) his upcoming departure from 
the Committee and the Board following the 2023 AGM. Similarly, 

Governance100    PureTech Health plc   Annual Report and Accounts 2023

Report of the Audit Committee continued

Significant issues considered in relation to the 
financial statements
The Committee considered, in conjunction with management and 
the external auditor, the significant areas of estimation, judgement 
and possible error in preparing the financial statements and 
disclosures, discussed how these were addressed and approved 
the conclusions of this work. The principal areas of focus in this 
regard were the determination of the accounting treatment 
for the sale of future royalties, and valuation of Level 3 financial 
instruments, including those related to Vedanta Biosciences and 
Sonde Health.

Going concern
At least annually, the Committee considers the going concern 
principle on which the financial statements are prepared. 
As a business which seeks to fund the development of its 
Internal Programs, as well as support its Founded Entities 
with further capital, the business model is currently inherently 
cash consuming.

As of December 31, 2023, we had sufficient funding to extend 
operations into 2027 based on the Company’s strategic 
operating plan.

Accounting treatment for the sale of future royalties
An area of judgment in our financial statements and, therefore 
audit risk, relates to the determination of the appropriate 
accounting treatment for the Royalty Agreement, which at year 
end resulted in a sale of future royalty liability of $110.2 million. We 
considered the pertinent terms and underlying economics of the 
agreement in determining the appropriate accounting treatment.

Therefore, while an inability of the Internal Programs and Founded 
Entities to raise funds through equity financings with outside 
investors, strategic arrangements, licensing deals or debt facilities 
may require us to modify our level of capital deployment into our 
Internal Programs and Founded Entities or to more actively seek 
to monetize one or more Founded Entities, it would not threaten 
our viability overall.

Valuation of financial instruments
An area of judgement in our financial statements and, therefore 
audit risk, relates to the valuation of investments held at fair 
value that do not have a quoted active market price which at year 
end had a carrying value totaling $25 million (2022 – $11 million). 
We considered the underlying economics of the valuations 
and sought external expertise in determining the appropriate 
valuation of the financial investments. These valuations rely, in 
large part, on the capital structure, values of recent transactions 
and market movement. These values also determine the amount 
of gain (loss) on the financial instruments. The Committee believes 
that we considered the pertinent terms and underlying economics 
of each of the financial instruments, as well as the advice of 
external experts, and as such concluded that the financial 
Instruments were appropriately recorded.

Regulatory compliance
Ensuring compliance for FCA regulated businesses also 
represents an important control risk from the perspective of the 
Committee. We engage with outside counsel and other advisors 
on a regular basis to ensure compliance with legal requirements.

Review of Annual Report and Accounts and Half-
yearly Report
The Committee carried out a thorough review of our 2023 Annual 
Report and Accounts and our 2023 Half-yearly Report resulting in 
the recommendation of both for approval by the Board. In carrying 
out its review, the Committee gave particular consideration to 
whether the Annual Report, taken as a whole, was fair, balanced 
and understandable, concluding that it was. It did this primarily 
through consideration of the reporting of our business model 
and strategy, the competitive landscape in which it operates, the 
significant risks it faces, the progress made against its strategic 
objectives and the progress made by, and changes in fair value of, 
its Founded Entities during the year.

Compliance
The Committee has had a role in supporting our compliance 
with the Governance Code, which applies to us for the 2023 
financial year. The Board has included a statement regarding our 
longer-term viability on page 65. The Committee worked with 
management and assessed that there is a robust process in place 
to support the statement made by the Board.

Similarly, the Committee worked with management to ensure 
that the current processes underpinning its oversight of internal 
controls provide appropriate support for the Board’s statement 
on the effectiveness of risk management and internal controls.

Risk and internal controls
The principal risks we face are set out on pages 60 to 64 and in the 
Additional Information section from pages 186 to 223.

The Committee has directed that management engage in a 
continuous process to review internal controls around financial 
reporting and safeguarding of assets. Management has engaged 
external advisors to complete internal control testing on behalf 
of management for the 2023 financial year and the results were 
presented to the Committee. 

Based on the above, we have satisfied ourselves that we have 
adequate controls and that our internal control over financial 
reporting is effective for the year ended December 31, 2023.

We have a formal whistleblowing policy. The Committee is 
satisfied that the policy has been designed to encourage staff to 
report suspected wrongdoing as soon as possible, to provide staff 
with guidance on how to raise those concerns, and to ensure staff 
that they should be able to raise genuine concerns without fear of 
reprisals, even if they turn out to be mistaken.

GovernanceReport of the Audit Committee continued

PureTech Health plc   Annual Report and Accounts 2023    101  

Internal audit
We do not maintain a separate internal audit function. This is 
principally due to our size, where close control over operations 
is exercised by a small number of executives. In assessing the 
need for an internal audit function, the Committee considered 
the risk assessment performed by management to identify key 
areas of assurance and the whole system of internal financial 
and operational controls. The Company achieves internal 
assurance by performing the risk assessment of the key areas of 
assurance and maintaining related key internal controls, as well as 
engaging external advisors to perform internal control testing, as 
described above.

External audit
We have engaged PricewaterhouseCoopers LLP (UK) as our 
Auditor since 2023. The current audit partner is Sam Taylor who 
has been our audit partner since June 2023. 

The effectiveness of the external audit process is dependent on 
appropriate risk identification. In November 2023, the Committee 
discussed the Auditor’s audit plan for 2023. This included a 
summary of the proposed audit scope and a summary of what the 
Auditor considered to be the most significant financial reporting 
risks facing us together with the Auditor’s proposed audit 
approach to these significant risk areas. The main areas of audit 
focus for the year were (a) Valuation of financial instruments and 
(b) the accounting model for the sale of a future royalty liability. 

Appointment and independence
The Committee advises the Board on the appointment of the 
external Auditor and on its remuneration both for audit and 
non-audit work, and discusses the nature, scope and results 
of the audit with the external Auditor. The Committee keeps 
under review the cost-effectiveness and the independence and 
objectivity of the external Auditor. Controls in place to ensure 
this include monitoring the independence and effectiveness of 
the audit, a policy on the engagement of the external Auditor to 
supply non-audit services, and a review of the scope of the audit 
and fee and performance of the external Auditor.

Non-audit work
The Committee approves all fees paid to the Auditor for 
non-audit work.

Where appropriate, the Committee sanctions the use of 
PricewaterhouseCoopers LLP for non-audit services in 
accordance with our non-audit services policy. During 2023 
PwC did not provide any non-audit related services, apart from 
non-audit fees in connection with access to the firm’s accounting 
research and disclosure database. Therefore, the ratio of non-
audit work to audit work was nil, which the Committee is satisfied 
does not breach the independence of PricewaterhouseCoopers.

strategic plan. The Remuneration Committee also recommends 
and monitors the level and structure of remuneration for senior 
management. The Remuneration Committee shall, in consultation 
with the interim Chairman and/or the Chief Executive Officer, 
determine the total individual remuneration package of each 
Executive Director, including share awards. The Remuneration 
Committee shall also have regard to current information for 
remuneration in other companies of comparable scale and 
complexity and can appoint remuneration consultants to 
assist in such process. The Remuneration Committee also has 
responsibility to review the design of all share incentive plans 
and determine awards under such plans. A full copy of the 
Remuneration Committee’s Terms of Reference is available on 
request from the Company Secretary and within the Investors 
section of the Company’s website at www.puretechhealth.com.

Committee membership
The Remuneration Committee consists of Dr. LaMattina, Dr. 
Kucherlapati and Ms. Mazumdar-Shaw, with Dr. LaMattina serving 
as Chair of the Committee. The biographies of the Committee 
members can be found on pages 82 to 83. The Committee met 
three times during the year, with each Committee member in 
attendance for all three meetings. The Committee also acted by 
unanimous written consent seven times during the year. During 
2023, the Chief Executive Officer and the President were invited 
to all of the meetings, with Ms. Zohar attending two of the three 
meetings and Dr. Chowrira attending all three meetings. However, 
no Executive Director was permitted to participate in discussions 
or decisions about his or her personal remuneration.

Our Remuneration Policy
The success of PureTech depends on the motivation and retention 
of our highly skilled workforce with significant expertise across 
a range of science and technology disciplines, as well as our 
highly-experienced management team and seasoned Directors. 
PureTech’s Remuneration Policy is therefore an important part of 
our business strategy. Our guiding principle is to provide market 
competitive remuneration packages, including with respect to 
cash compensation in the form of base salary, annual bonuses 
and benefits as well as share based compensation, benchmarked 
against data generated from our local markets to enable us to put 
together and retain a top tier team.

The Directors’ Remuneration Policy was approved by 
shareholders at the 2021 AGM with 83.9% support, and the 
Remuneration Report was approved by shareholders at the 2023 
AGM with 95.5% support. At the 2023 AGM, we also received 
96.8% support for a proposal for a new Performance Share Plan 
to help us better manage the potential dilution from equity 
incentives, a critically important part of our overall compensation 
program. The Committee is grateful for this level of investor 
support, which clearly indicates that shareholders are sympathetic 
to our approach of balancing UK standards on remuneration 
with practices designed to ensure that PureTech can remain 
competitive against U.S. peer companies in the biopharma sector.

The Directors’ Remuneration Report is split into three 
sections, namely:

 — This Annual Statement: summarizing and explaining the major 

decisions on Directors’ remuneration in the year;

 — The Directors’ Remuneration Policy: setting out the framework 
for remuneration for our Directors on pages 106 to 112; and

 — The Annual Report on Remuneration: setting out the 

implementation of the Remuneration Policy in the year ended 
December 31, 2023 and the intended implementation for the 
year ending December 31, 2024 on pages 113 to 122.

The current Directors’ Remuneration Policy was last approved 
at the 2021 AGM, and such approval is effective until the 
December 31, 2024. We are asking shareholders to approve a 
new Remuneration Policy at the 2024 AGM by way of a binding 
vote. The Directors’ Remuneration Report (excluding that part 
of the report containing the Directors’ Remuneration Policy on 
pages 106 to 112) and is also subject to a shareholder vote at this 
year’s AGM. The vote to approve the Directors’ Remuneration 
Report is advisory only and does not affect the actual historical 
remuneration paid to any individual Director. We will also be 
asking shareholders to approve a separate AGM proposal 
to amend the Performance Share Plan (“PSP”) to align with 
the new Policy.

Committee responsibilities 
The Remuneration Committee’s primary purpose is to assist the 
Board in determining the Company’s remuneration policies. The 
Remuneration Committee has the responsibility for setting the 
remuneration policy for all Executive Directors and the Chairman 
of the Company, including pension rights and compensation 
payments, and in determining such policy must take into account 
all factors which it deems necessary including regulatory 
requirements, with the objective of attracting, retaining and 
motivating executive management having regard to views of 
shareholders and stakeholders and the risk appetite of the 
Company and alignment to the Company’s long term goals and 

GovernanceDirectors’ Remuneration Report continued

PureTech Health plc   Annual Report and Accounts 2023    103  

Ahead of the requirement to seek shareholder approval for 
a new Directors’ Remuneration Policy at the 2024 AGM, the 
Remuneration Committee has reviewed whether any changes 
are required, taking into account the evolution of the business 
and, in particular, the ongoing pressures in what remains a 
very competitive U.S. market for talent. At the same time, the 
Committee recognizes the need for remuneration practices 
to broadly align with UK standards and the expectations of UK 
investors. We have sought to develop a package which remains 
consistent with the principles of the UK Corporate Governance 
Code and best practice.

The key aims of the Remuneration Policy and the Code principles 
to which they relate are as follows:

 — promote our long-term success (Code principle: 

Proportionality);

 — attract, retain and motivate high caliber senior management 
and focus them on the delivery of our long-term strategic 
and business objectives (Proportionality, alignment to 
culture and risk);

 — be simple and understandable, both externally and internally 

(Clarity, simplicity, predictability and proportionality);

 — achieve consistency of approach across senior management 
to the extent appropriate and informed by relevant market 
benchmarks (Clarity and alignment to culture); and

 — encourage widespread equity ownership across the executive 
team to ensure a long-term focus and alignment of interest 
with shareholders (Alignment to culture, risk).

The new Remuneration Policy continues many of the features of 
the existing Policy, including with respect to fixed remuneration, 
annual bonuses and shareholding guidelines. We are, however, 
making an important change to long-term equity incentive 
provision for the Executive Directors.

Currently, the Executive Directors receive annual grants of 
performance shares at levels of up to 600 percent of base salary 
for the Chief Executive Officer and up to 300 percent of base 
salary for any other Executive Directors. The shares vest subject 
to the achievement of performance conditions over a three-year 
period, with a subsequent two-year post-vesting holding period. 
While this focus on performance shares is consistent with normal 
practice for UK-listed companies, it is unusual for U.S. companies 
in the biopharma sector, where restricted stock and stock 
options are significantly more common. PureTech competes for 
talent with other companies based in the biotech cluster around 
Boston, and we face increasing challenges to retain key people 
in a local market where competitor organizations are offering 
large equity grants to senior employees without long-term 
performance conditions.

In the interests of providing a suitably competitive package for 
PureTech’s leaders which is relevant in the local context, the new 
Policy introduces certain time-vesting restricted shares into 
the long-term incentive structure for the Executive Directors. 
Under this approach, 50 percent of the total long-term equity 
component will remain as performance shares, with the remaining 
50 percent being comprised of time-vesting restricted shares. To 
ensure ongoing competitiveness, total grant levels will remain 
unchanged, so that the Chief Executive Officer’s award under this 
new structure will be up to 300 percent of salary in performance 
shares and 300 percent in time-vesting restricted shares. For 
any other Executive Directors, the grant levels will be up to 150 
percent in performance shares and 150 percent in time-vesting 
restricted shares.

The vesting of the performance shares will continue to be subject 
to the satisfaction of challenging performance conditions over 
a three-year period, with a significant proportion linked to TSR. 
The time-vesting restricted shares will vest subject to continued 
employment, albeit with a requirement that the Remuneration 
Committee is satisfied with Company and individual performance 
over the vesting period. The time-vesting restricted shares will 
vest in three equal annual instalments commencing one year 
from the initial grant date, in line with common U.S. practice. 
Both performance and time-vesting restricted shares will remain 
subject to a two-year post-vesting holding period. Vesting 
provisions with respect to time-vesting restricted shares may 
be altered at the discretion of the Remuneration Committee, 
provided that the vesting periods are not shorter than what is 
described previously.

We recognise that the introduction of time-vesting restricted 
shares is a significant change to the incentive construct. However, 
it results in a hybrid approach which is directly in line with market 
practice in the sector, and helps us provide our leaders with 
compensation packages which are more competitive in the local 
context, while also putting the business in a better position to 
attract the very best talent going forward.

One other change we are making to the Remuneration Policy 
relates to Non-Executive Director compensation. Currently, Non-
Executive Directors receive a mixture of cash and ordinary shares 
in PureTech. The fee levels payable to date have been significantly 
below the levels typically payable for experienced Non-
Executive Directors at U.S. companies in our sector. Given the 
Board’s policy of appointing high calibre Directors who can add 
considerable value based on their knowledge and experience, 
we intend to address the current market shortfall in two ways. 
First, over the course of 2024 we will be reviewing the level of 
cash compensation, to ensure that it is consistent with the very 
significant contributions made by the Non-Executive Directors. 
Full details of any changes will be disclosed in next year’s 
Directors’ Remuneration Report. Second, the new Remuneration 

Governance104    PureTech Health plc   Annual Report and Accounts 2023

Directors’ Remuneration Report continued

Policy provides more flexibility in the way Non-Executive Directors 
can be paid, by increasing the equity element of the fee from 
$50,000 to up to $150,000. 

The full Directors’ Remuneration Policy is set out on 
pages 106 to 112.

Amendment to Performance Share Plan
The purpose of the separate proposal to amend the performance 
share plan is to align the plan document with the remuneration 
policy being proposed at the upcoming AGM. This amendment 
will facilitate an important element of our overall compensation 
program and aligns with our historic approach of balancing UK 
standards on remuneration with practices designed to ensure that 
PureTech can remain competitive against U.S. peer companies in 
the biopharma sector.

Performance and reward in 2023
During 2023, PureTech delivered strong execution and 
achievement of key strategic and financial goals, which has been 
reflected in the annual bonus outcome. The Company delivered 
substantial growth and generated momentum to support future 
growth in the coming years as our balance sheet, Founded Entities 
equity and royalty stakes, and Internal Programs position PureTech 
with the strength to build substantial value for shareholders 
in the current environment. This growth is due in large part to 
(i) significant development and advancement of our Internal 
Programs and activities initiated or progressed to potentially 
bring these innovative therapies to market, (ii) monetization 
of PureTech’s royalty in Karuna Therapeutics’ KarXT for up to 
$500 million, with $100 million in cash paid up front, (iii) completion 
of various strategic sourcing and strategic planning initiatives 
with the forward looking goal to enhance shareholder value, 
(iv), substantial development and expansion of the Company’s 
intellectual property portfolio and (v) key support provided to 
the Founded Entities as their businesses progress and, in certain 
cases, execute key transactions or financings. This increase in 
value, together with management’s operational performance 
at PureTech and within Internal Programs and Founded Entities, 
resulted in the Remuneration Committee approving 75% of the 
target performance goals. In line with our standard approach, 
the Committee then reviewed the overall performance of 
the Company and the individual Executive Directors before 
determining the final bonus payout. The Committee considered 
operational performance, the overall growth of the business 
during the year, the extent to which the target performance 
goals had in some cases been exceeded and the individual 
contributions of the Executive Directors. Following this exercise, 
the Committee determined that a bonus equal to 75% of target (or 
37.5% of base salary) was to be awarded to the Executive Directors.
The Committee focused on the monetization of the KarXT royalty 
as an exceptional achievement, and also considered at length 
the successful activities of certain Founded Entities and the value 
created for PureTech thereby, especially Karuna in light of its sale 
to Bristol Myers Squibb. Following this exercise of review, the 
Committee determined to exercise discretion to increase the 
bonus payment from 75% of target to 200% of target. This resulted 

in a bonus payment of 100% of base salary to be awarded to the 
Executive Directors. The Committee is of the view that this is 
appropriate in recognizing the Executive Directors’ achievements 
in 2023. See highlights of 2023 on pages 1 to 6. 

In relation to the PSP, PureTech’s performance over the last three 
financial years was very strong in terms of the achievement of 
strategic objectives despite such performance not translating 
to growth in the Company’s share price. Overall, the share price 
declined from an average price of 285 pence during the last three 
months of 2020 to an average price of 164 pence during the last 
three months of 2023. However, strong strategic performance 
over the three-year performance period resulted in PSP awards 
granted to the executive management team, including the two 
Executive Directors, in 2021 vesting at a level of 35.3 percent after 
the end of the 2023 financial year.

Full details of payments to the Executive Directors in 2023 
can be found later in this report. As part of the Remuneration 
Committee’s review of overall compensation arrangements in the 
Fall of 2023, and taking into account multi-year periods compared 
to Executive Directors of U.S. and UK companies of a similar 
size to PureTech, the Committee concluded that a significant 
deficiency existed, and determined to make significant lump 
sum benefits payments to the Executive Directors to align with 
allowances often provided to other Executive Directors in both 
the U.S. and the UK. These allowances, related to housing and 
transportation, had not been provided to Executive Directors 
of PureTech since PureTech’s IPO in 2015 and the Committee felt 
that it was appropriate to address this important competitive 
element that would typically be part of an overall compensation 
regime. As a result, we agreed to make two payments to the then 
serving Chief Executive Officer, with the first $1.5 million paid in 
2023 and the second $1.0 million paid in early 2024. A one-time 
$1.0 million payment was also made to the then serving President 
for the same reasons in early 2024. Full details of the payments are 
set out in the Directors’ Remuneration Report. We recognize that 
payments of this nature are relatively unusual, but they are 
considered to be in shareholders’ interests as they ensure that we 
are fairly compensating our senior team in a manner consistent 
with common practice for other leaders in our sector, taking into 
account a period of under-reward in earlier years. As noted, the 
Remuneration Committee periodically considers the overall 
mix of benefits provided to all employees, including senior 
management team members, and does not currently anticipate 
making similar benefits payments in the near term.

The Committee believes the Remuneration Policy operated 
as intended during the year and that remuneration outcomes 
are appropriate, taking into account outcomes throughout 
the business, company and individual performance and the 
stakeholder experience.

Board changes since the year end
As announced on April 9, 2024  in connection with the foundation 
of Seaport Therapeutics, Inc. (Seaport), our Chief Executive 
Officer Daphne Zohar left the business with immediate effect to 
become Chief Executive Officer of Seaport, while also serving as 
senior adviser and observer to the Board of Directors of PureTech.

Ms. Zohar has been paid base salary, benefits and pension up 
to April 8, 2024, and is not eligible for the 2024 bonus award. 
However, outstanding PSP awards will continue to vest for the 
duration of her service as senior advisor and observer to the 
Board. The two-year post-vesting holding period for PSP awards 
will continue to apply, and Ms. Zohar is also required to maintain a 
minimum level of shareholding for at least two years following her 
departure, in line with the Directors’ Remuneration Policy.

There are no compensation payments for loss of office. Full details 
of 2024 remuneration will be disclosed in next year’s Directors’ 
Remuneration Report.

The compensation package for her successor as Chief Executive 
Officer, Bharatt Chowrira, is described in the next section. There 
are no other compensation elements in connection with his 
appointment as Chief Executive Officer beyond those set out.

The year ahead
For 2024, the following key decisions have been made in relation to 
how the Policy will be implemented:

 — Base salaries for the Executive Director were increased by 
3.2 percent, which is in line with the average increase for 
the general workforce taking into consideration a number 
of factors, with a primary consideration being the current 
inflationary pressures in the United States.

 — Since this decision was taken in relation to base salaries, 
as noted above there has been a Chief Executive Officer 
succession. The Committee carefully considered the base 
salary for Bharatt Chowrira, the new Chief Executive Officer, 
and determined that this should be $850,000 effective from 
the date of appointment. This took into account the scope of 
the role and the appropriate market positioning against key 
competitors, considering base salary and the other elements 
of the package.

 — The annual bonus target and maximum will remain at 

50 percent and 100 percent of base salary, respectively and for 
the new Chief Executive Officer will be based on the blended 
base salary paid over the year; and

 — The grants of PSP awards in 2024 will remain at the level of 
600 percent of base salary for the Chief Executive Officer, 
in line with the limits as set out in the Policy. Subject to 
shareholder approval of the new Remuneration Policy, half of 
the awards will be granted as performance shares and half as 
time-vesting restricted shares.

 — For the performance share element, we are retaining a mix of 
performance measures linked to absolute TSR, relative TSR 
and key strategic metrics which are tied to business progress 
over the three-year performance period. We have made a 
small change to the weightings for these different elements, 
with the 2024 award set to be based 50 percent on TSR and 
50 percent on strategic metrics.

 — For the Non-Executive Directors, as noted above, our intention 
is to increase the current equity portion of fees from $50,000 to 
$150,000, with this additional $100,000 either being awarded 
in the form of a higher grant of PureTech ordinary shares or in 
subsidiary equity, in line with new Remuneration Policy.

 — Levels of cash compensation for the Non-Executive Directors 

will be reviewed later in 2024.

Remuneration for other Colleagues
In addition to matters relating to Executive Directors’ 
remuneration, the Committee also reviews the compensation 
policies for the wider employee base, with a particular focus on the 
use of equity compensation throughout the whole organization. 
PureTech grants its employees awards of performance shares 
and restricted shares under the PSP as well as market-value stock 
options, helping to ensure a degree of competitiveness against 
other U.S. companies operating in the same sector. Following 
shareholder approval of the new Performance Share Plan in 2023, 
we have greater flexibility in operating the plan given the new 
dilution limits within the plan. As argued last year, we believe 
that our new approach represents a suitable balance between 
UK good practice and the commercial realities of operating in a 
competitive market for talent in our sector in the U.S. 

Closing comments
The Committee is comfortable that the operation of the Policy 
for 2023 has demonstrated a robust link between performance 
and reward given the successes recorded during the year and that 
discretion, where exercised, has been in line with shareholder 
interests. The Committee believes the new Remuneration Policy, 
and the proposed operation of the Policy for 2024 is appropriate 
and continues to strike a suitable balance between UK investor 
expectations and the realities of operating in a competitive 
U.S. market.

The Committee looks forward to shareholders’ support at 
the 2024 Annual General Meeting for the advisory resolution 
covering this Annual Statement and the Annual Report on 
Remuneration and the separate resolution to approve the new 
Remuneration Policy.

Governance106    PureTech Health plc   Annual Report and Accounts 2023

Directors’ Remuneration Policy

This part of the Directors’ Remuneration Report sets out the Remuneration Policy for the Executive Directors and has been prepared 
in accordance with the provisions of the Companies Act 2006, The Large and Medium Sized Companies and Groups (Accounts and 
Reports) Regulations 2008 and the subsequent amendments, and the UK Listing Authority Listing Rules. In addition, the report has been 
prepared on a “comply or explain” basis with regard to the UK Corporate Governance Code 2018.

This Directors’ Remuneration Policy will be put to a binding shareholder vote at the Company’s AGM on June 13, 2024 and, if approved, 
is intended to apply for a period of three years from that date.

Changes to the Remuneration Policy
The policy being brought to shareholders for approval contains the following three changes:

 — Time-vesting restricted shares are being introduced into the long-term incentive structure for the Executive Directors, with 

50 percent of the total long-term equity component remaining as performance shares, and 50 percent being comprised of time-
vesting restricted shares. In the interests of ensuring ongoing competitiveness, maximum grant levels will remain unchanged.
 — The time-vesting restricted shares will vest over three years in three equal annual instalments commencing one year from the 

initial grant date, subject to continued employment and a Remuneration Committee assessment that individual and company 
performance has been satisfactory over the vesting period. Both performance and time-vesting restricted shares will remain subject 
to the same two-year post-vesting holding period as currently applies.

 — Increasing the annual equity grant of PureTech ordinary shares paid to our Non-Executive Directors from $50,000 to $150,000.

In addition, some minor changes to the wording of the Policy have been made in the interests of enhanced clarity.

Decision making process for determination, review and implementation of Directors’ Remuneration Policy
The Committee reviews the Policy and its operation to ensure it continues to support and align to the business strategy and 
appropriately reward the Executive Directors and takes into account relevant market practice, regulation and governance 
developments, institutional investor views and the views of our shareholders. The Committee also has regard to the remuneration 
arrangements, policies and practices of the workforce as a whole and takes this into account when reviewing Executive Director pay. 

The Policy is reviewed annually by the Committee. If changes are required, a new policy (or an amendment to the policy) will be put 
forward to shareholder vote prior to the normal triennial shareholder vote. The Committee consults with shareholders on remuneration 
proposals and will consider the feedback in finalizing the Policy. The Committee sought the views of major shareholders before 
confirming the Policy as set out below.

Operation of the Policy is considered annually for the year ahead, including metrics for incentives, weightings and targets. The 
Committee reviews operation for the prior year and considers whether, in light of the strategy, changes are required for the year ahead 
or if remuneration remains appropriate for the year ahead. Shareholders’ views may be sought depending on the changes proposed.

The Company can make long-
term incentive awards of either 
performance shares or time-
vesting restricted shares. 

For performance shares, vesting 
is dependent on the satisfaction 
of performance targets and 
continued service. Performance 
and vesting periods are normally 
three years. 

For time-vesting restricted 
shares, vesting is dependent 
on continued service and 
Remuneration Committee 
confirmation that Company 
and individual performance 
has been satisfactory over the 
vesting period. Vesting normally 
takes place in three equal annual 
tranches over a three-year 
period following grant.

All awards will be subject to a 
two-year post-vesting holding 
period during which vested 
shares cannot be sold other than 
to settle tax. This post-vesting 
period continues post-cessation 
of employment.

The Committee also has the 
discretion to adjust vesting 
levels of performance-related 
awards to override formulaic 
outcomes, taking into account 
similar factors as apply in 
relation to annual bonus 
awards, but by reference to 
the performance period.

The Committee requires 
that Executive Directors who 
participate in a long-term 
incentive plan operated by 
the Company retain half of the 
net shares vesting under any 
long-term incentive plan until 
a shareholding requirement 
is met.

For the Chief Executive Officer, 
600 percent of base salary. This 
will normally be split 300 percent 
of base salary in performance 
shares and 300 percent of base 
salary in time-vesting restricted 
shares.

For other Executive Directors, 
300 percent of base salary. This 
will normally be split 150 percent 
of salary in performance shares 
and 150 percent in time-vesting 
restricted shares. 

Participants may benefit from 
the value of dividends paid over 
the vesting period to the extent 
that awards vest. This benefit is 
delivered in the form of cash or 
additional shares at the time that 
awards vest.

Performance targets and recovery 
provisions 

For performance shares, the 
performance period is normally 
three years. 

Up to 25 percent of a performance 
share award vests at threshold 
performance (0 percent vests 
below this), increasing to 100 
percent pro-rata for maximum 
performance. Normally at least 
half of any performance share 
award will be measured against 
TSR targets with the remainder 
measured against relevant 
financial or strategic measures. 
Performance conditions are 
agreed by the Committee on 
an annual basis. 

For time-vesting restricted 
shares, there are no performance 
conditions other than the 
requirement for the Remuneration 
Committee to confirm a 
satisfactory level of Company and 
individual performance over the 
vesting period. 

Recovery and withholding 
provisions are in place for both 
performance and time-vesting 
restricted shares.

Minimum of 400 percent of base 
salary for the Chief Executive 
Officer and a minimum of 200 
percent of base salary for the 
other Executive Directors.

A portion of the compensation 
to Non-Executive Directors is in 
the form of PureTech Health plc 
ordinary shares.

Additional remuneration is 
payable for additional services 
to PureTech such as the 
Chairship of a Committee or 
membership on a Committee. 
Additional remuneration 
is also payable for services 
provided beyond those services 
traditionally provided as 
a director.

Taxable benefits may be 
provided and may be grossed 
up where appropriate. 

Notes: 
1 

In the event that the Company elects any non-U.S. Executive Directors, the 401k Plan may not be an appropriate pension arrangement. In such cases an alternative pension 
arrangement may be offered. Any such arrangement would not be higher than the pension rate operated for the majority of employees in that jurisdiction.

2  For those below Board level, a lower annual bonus opportunity and equity award size may apply. In general, these differences arise from the development of remuneration 

arrangements that are market competitive for the various categories of individuals, together with the fact that remuneration of the Executive Directors and senior executives 
places significant emphasis on performance-related pay.

3  The choice of the performance metrics for the annual bonus scheme reflects the Committee’s belief that incentive compensation should be appropriately challenging and linked 

to the delivery of the Company’s strategy. Further information on the choice of performance measures and targets is set out in the Annual Report on Remuneration.

4  The performance conditions applicable to the performance shares (see Annual Report on Remuneration) are selected by the Remuneration Committee on the basis that they 

reward the delivery of long-term returns to shareholders and are consistent with the Company’s objective of delivering superior levels of long-term value to shareholders while 
providing the Company with tools to successfully recruit and retain employees in the U.S.

5  For the avoidance of doubt, the Company reserves the right to honour any commitments entered into in the past with current or former Directors (such as the vesting/exercise 
of share awards) notwithstanding that these may not be in line with this Remuneration Policy. Details of any payments to former Directors will be set out in the Annual Report on 
Remuneration as they arise.

Governance110    PureTech Health plc   Annual Report and Accounts 2023

Directors’ Remuneration Policy continued

Recovery and withholding provisions
Recovery and withholding provisions (’’clawback and malus’’) may 
be operated at the discretion of the Remuneration Committee in 
respect of awards granted under the Performance Share Plan and 
in certain circumstances under the Annual Bonus Plan (including 
where there has been a material misstatement of accounts, or 
in the event of fraud, gross misconduct or conduct having a 
materially detrimental effect on the Company’s reputation). 

The issue giving rise to the recovery and withholding must be 
discovered within three years of vesting or payment and there is 
flexibility to recover overpayments by withholding future incentive 
payments and recovering the amount directly from the employee. 

In compliance with U.S. Securities and Exchange Commission 
reporting and Nasdaq listing standards, effective as of November 
8, 2023, the Committee has adopted a new Policy for Recovery of 
Erroneously Awarded Compensation. This new policy requires 
that the Remuneration Committee clawback excess incentive 
compensation from executive officers following a required 
accounting restatement where, based on the restated financials, 
executives would have missed the portion of the award tied to a 
specific financial performance metrics. 

The new policy covers restatements involving the financial 
measures within the Performance Share Plan and Annual Bonus 
Plan and is intended to apply in addition to and in concert with the 
Company’s existing clawback and malus provisions.

Discretions in the policy
To ensure the efficient administration of the variable incentive 
plans outlined above, the Committee will apply certain 
operational discretions. These include the following:

 — selecting the participants in the plans on an annual basis;
 — determining the timing of grants of awards and/or payments;
 — determining the quantum of awards and/or payments (within 

the limits set out in the Policy table above);

 — reviewing performance against LTI performance metrics;
 — determining the extent of vesting based on the assessment 

of performance (where relevant);

 — making the appropriate adjustments required in certain 

circumstances, for instance for changes in capital structure;
 — deciding how to settle awards made under the plans, e.g. in 

cash, shares, nil-cost options or as otherwise permitted under 
the plan rules;

 — overriding formulaic outcomes of incentive plans if 

determined by the Committee not to be reflective of 
company performance;

 — determining “good leaver” status for incentive plan purposes 

and applying the appropriate treatment; further details 
on the discretion applicable in relation to leavers are set 
out on page 112;

 — undertaking the annual review of weighting of performance 
measures and setting targets for the annual bonus plan 
and other incentive schemes, where applicable, from 
year to year; and

 — discretion, in the event of a change in control of the 

Company, to determine that time pro-rating shall not apply 
to outstanding awards.

If an event occurs which results in the annual bonus plan or 
PSP performance conditions and/or targets being deemed no 
longer appropriate (e.g. material acquisition or divestment), 
the Committee will have the ability to adjust appropriately the 
measures and/or targets and alter weightings, provided that the 
revised conditions are not materially less challenging than the 
original conditions.

not included in these charts as It Is not expected that similar payments of this nature will be made in 2024.

2  The On-Target level of bonus is taken to be 50 percent of the maximum bonus opportunity (50 percent of salary). The On-Target level of PSP vesting is assumed to be 50 percent 
of the face value of the performance share element, i.e. 150 percent of base salary for the CEO, plus 100 percent of the face value of the time-vesting restricted share element, 
i.e. 300 percent of base salary for the CEO. These values are included in addition to the components/values of Minimum remuneration.

3  Maximum assumes full bonus pay-out (100 percent of base salary) and the full face value of the proposed PSP awards, i.e. 600 percent of base salary for the CEO, in addition to 

fixed components/values of Minimum remuneration.

4  No share price growth has been factored into the calculations of minimum, target and maximum compensation. An additional maximum scenario has been shown which assumes 

50% share price appreciation for the performance-related PSP during the performance period.

Approach to recruitment and promotions
The remuneration package for a new Executive Director would 
be set in accordance with the terms of the Company’s prevailing 
approved Remuneration Policy at the time of appointment and 
take into account the skills and experience of the individual, the 
market rate for a candidate of that experience and the importance 
of securing the relevant individual.

Salary would be provided at such a level as required to attract the 
most appropriate candidate and may be set initially at or above 
mid-market level.

Additionally, salary may be provided at a below mid-market level 
on the basis that it may progress towards the mid-market level 
once expertise and performance has been proven and sustained. 
The annual bonus and long-term incentive awards would be 
limited in line with the policy, meaning that bonus opportunity 
would be limited to 100% of base salary and long-term incentive 
awards would be limited to 600% (in the case of a new Chief 
Executive Officer) or to 300% (in the case of a new Executive 
Director who is not a Chief Executive Officer). Depending on 
the timing of the appointment, the Committee may deem it 
appropriate to set annual bonus performance conditions for 

such appointee that are different than those applicable to the 
incumbent Executive Directors. A PSP award can be made shortly 
following an appointment.

In addition, the Committee may offer additional cash and/
or share-based elements to replace deferred or incentive pay 
forfeited by an executive leaving a previous employer if required 
to facilitate, in exceptional circumstances, the recruitment of the 
relevant individual. It would seek to ensure, where possible, that 
these awards would be consistent with awards forfeited in terms 
of vesting periods, expected value, performance conditions and 
delivery mechanism.

For appointment of an Executive Director who was employed 
by the Company prior to the appointment, any variable pay 
element awarded in respect of the prior role may be allowed to 
pay out according to its terms. In addition, any other ongoing 
remuneration obligations existing prior to appointment 
may continue.

For any Executive Director appointment, the Committee may 
agree that the Company will meet certain relocation and/or 
incidental expenses as appropriate.

Directors’ Remuneration Policy continued

Service contracts
Executive Directors’ service contracts do not provide for 
liquidated damages, longer periods of notice on a change 
of control of the Company or additional compensation on an 
Executive Director’s cessation of employment with us, except as 
discussed below.

The Committee’s Policy is to offer service contracts for Executive 
Directors with notice periods of no more than 12 months, and 
typically between 60 to 180 days.

Service contracts provide for severance pay following termination 
in the case that employment is terminated by the Company 
without ‘cause’, or by the employee for ‘good reason’. In this 
case severance pay as set out in the contract is no greater than 
12-months’ base salary and is aligned to the duration of any 
restrictive covenants placed on the employee. Service contracts 
may also provide for the continuation of benefits but for no longer 
than a 12-month period post termination.

Service contracts also provide for the payment of international 
tax in non-U.S. jurisdictions if applicable to the Executive 
Director. They also can provide for garden leave and, if 
required by applicable law, the recovery and withholding of 
incentive payments.

Service contracts are available for inspection at the company’s 
registered office.

Policy on termination of employment
The Policy on termination is that the Company does not 
make payments beyond its contractual obligations and the 
commitments entered into as part of any incentive plan operated 
by the Company. In addition, Executive Directors will be expected 
to mitigate their loss. The Committee ensures that there have 
been no unjustified payments for failure.

An Executive Director may be eligible for an annual bonus 
payment for the final year in which that Director served as an 
employee, provided that they are deemed to be a ’good leaver’. If 
so, any such annual bonus payment will be subject to performance 
testing and a pro-rata reduction will normally be applied based on 
the time served during the relevant financial year.

The default treatment for any share-based entitlements under the 
PSP is that any unvested outstanding awards lapse on cessation 
of employment. However, in certain prescribed circumstances, 
or at the discretion of the Remuneration Committee, ’good 
leaver’ status can be applied. In these circumstances, a 
participant’s awards will vest subject to the satisfaction of the 
relevant performance criteria (for performance share awards) 
and, ordinarily, on a time pro-rated basis, with the balance of the 
awards lapsing. The two-year post vest holding period will usually 
continue to apply. The Committee has discretion to permit the 
early vesting at the date of cessation of employment, again based 
on performance (for performance share awards) and ordinarily on 
a time pro-rated basis.

In addition, the Company can pay for any administrative expenses, 
legal expenses or outplacement services arising from the 
termination where considered appropriate.

External appointments
The Board can allow Executive Directors to accept appropriate 
outside commercial Non-Executive Director appointments 
provided that the duties and time commitment required 
are compatible with their duties and time commitment as 
Executive Directors.

Non-Executive Directors
Non-Executive Directors are appointed as a Non-Executive 
Director of the Company by a letter of appointment. These 
letters usually provide for a notice period of one month from the 
Company and the Non-Executive Director prior to termination.

Consideration of shareholder views
The Committee will carefully consider shareholder feedback 
received in relation to the AGM each year. This feedback, plus 
any additional feedback received during any meetings from time 
to time, is then considered as part of the annual review of the 
Remuneration Policy.

The Company will seek to engage directly with major shareholders 
and their representative bodies should any material changes 
be proposed to the Remuneration Policy or its implementation. 
Details of votes cast for and against the resolutions to approve 
the Remuneration Policy and the prior year’s remuneration report 
and any matters discussed with shareholders during the year will 
be set out in the Annual Report on Remuneration. The Company 
consulted with shareholders in early 2024, in relation to new 
Remuneration Policy.

Consideration of our employment conditions generally
To ensure a coherent cascade of the Remuneration Policy 
throughout the organization, no element of remuneration is 
operated solely for Executive Directors and all elements of 
remuneration provided to the Executive Directors are generally 
operated for other employees, including participation in stock-
based incentive plans. In addition, the Committee considers 
the general base salary increase for the broader employee 
population when determining the annual salary increases for the 
Executive Directors. The Remuneration Committee has general 
responsibility for determining pay for senior management as well 
as Executive Directors. Employees (other than senior executives) 
have not been consulted in respect of the design of our 
Remuneration Policy, although the Committee will keep this under 
review. The Remuneration Committee seeks employee feedback 
with respect to the overall compensation policies and practices 
from the Executive Directors and other members of Management, 
who provide insights based on information gathered through 
routine employee engagement.

Implementation of the Remuneration Policy for the year ending December 31, 2024
Base salary
The Committee reviewed the base salary levels for the Executive Directors in early 2024 and an increase of 3.2 percent was awarded. 
This increase was in line the average increase for the general workforce, which was largely driven by cost of living considerations in the US. 
Following this annual increase, Dr. Chowrira’s base salary was increased as part of his appointment as Chief Executive Officer in April 2024.

Pension
We will continue to contribute under the 401k Plan subject to the maximum set out in the Policy table.

Benefits
Benefits provided will continue to include housing allowance, transportation allowance, private medical, disability and dental cover. 
As explained in the Annual Statement from the Chair of the Remuneration Committee, benefits payments related to housing and 
transportation allowance of $1.0 million were made to both the Chief Executive Officer and the former Chief Executive Officer in 
early 2024, though those payments are reflected in the 2023 Single Total Figure of Remuneration for each Director set forth below. 
Additional payments of this type are not expected in 2024.

Annual bonus
For 2024, the operation of the annual bonus plan will be similar to the plan’s operation in 2023. The maximum annual bonus will continue 
to be 100 percent of base salary for the Executive Director based on the blended base salary paid over the year. The 2024 annual bonus 
will be based on development goals and strategic development of our Internal Programs, financial and capital markets based goals. The 
performance metrics and targets will be disclosed in the FY2024 Annual Report and Accounts given that they are commercially sensitive 
at the current time.

Long-term incentives
Awards under the PSP will be made to the Executive Director in 2024. As explained in the Annual Statement from the Chair of the 
Remuneration Committee, subject to shareholder approval of the new Remuneration Policy at the AGM, the Chief Executive Officer 
will receive a performance share award with a face value of 300 percent of base salary and a restricted share award with a face value of 
300 percent of base salary. 

The performance share awards will be subject to the performance conditions described below, measured over the three-year period 
ended 31 December 2026. As a clinical-stage therapeutics company, the Company believes that TSR is an appropriate and objective 
measure of the Company’s performance. In addition, measuring TSR on both an absolute and relative basis rewards our management 
team for absolute value creation for our shareholders whilst also incentivizing outperformance of the market. To provide a balance to the 
TSR performance conditions that is more directly based on Management’s long term strategic performance, TSR is complemented by 
measures linked to strategic delivery. There will be a robust assessment of the achievement of the strategic targets over the three year 
period with full disclosure in the Directors’ Remuneration Report following the end of the performance period.

Further detail of the performance conditions is set out below:

 — 30 percent of the performance shares under award will vest based on the achievement of absolute TSR targets.
 — 20 percent of the performance shares under award will vest based on the achievement of a relative TSR performance condition, 

10 percent each against two benchmarks (explained below).

 — 50 percent of the performance shares under award will vest based on the achievement of strategic targets.

The change in the weightings between TSR and strategic targets reflects the nature of the business and the critical importance of 
meeting specific milestones and developing the portfolio of companies within which PureTech has an interest.

Governance114    PureTech Health plc   Annual Report and Accounts 2023

Annual Report on Remuneration continued

The minimum performance target for the absolute TSR portion of the performance share award will be TSR equal to 10 percent per 
annum, whilst the maximum target will be TSR equal to 20 percent per annum. Relative TSR will be measured against the constituent 
companies in the FTSE 250 Index (excluding Investment Trusts) and the MSCI Europe Health Care Index (each benchmark applying to  
10 percent of the performance share award, respectively). The minimum performance target will be achievement of TSR equal to the 
median company in the Index and the maximum performance target will be achievement of upper quartile TSR performance. 25 percent 
of each element of the TSR targets will vest for threshold performance. Strategic measures will be based on the achievement of 
milestones and other qualitative measures of performance over the performance period. Strategic targets will be set at the outset based 
on development of Internal Programs, financial achievements, including monetization of Founded Entities, product pipeline growth, 
operational excellence, strategic development or transaction related goals and other shareholder value enhancing metrics in line with 
our strategic plan. Full disclosure of the measures, weightings and strategic targets will be made retrospectively.

The Committee believes that this combination of measures is appropriate. TSR measures the success of our management team in 
identifying and developing new therapeutics whilst strategic targets help incentivize our management team through the stages which 
ultimately result in successful therapeutics.

Any performance shares which vest will be subject to a two-year post-vesting holding period.

The restricted shares to be granted to the Executive Directors will vest subject to continued employment and a Remuneration 
Committee assessment that Company and individual performance has been satisfactory. In line with normal practice in the United 
States, vesting will take place in three equal annual tranches over three years. For each tranche there will be a two-year post-vesting 
holding period.

Non-Executive Directors
Fees for our Board of Directors have been reviewed for 2024. The level of cash compensation is not being increased for 2024 although, 
as noted in the Annual Statement from the Chair of the Remuneration Committee, a further review will be undertaken later this year in 
the interests of ensuring ongoing competitiveness. 

The Board intends to increase the equity component of compensation from $50,000 to $150,000. Full details will be provided in next 
year’s Directors’ Remuneration Report.

As our Board of Directors consists of leading experts with the experience of successfully developing technologies and bringing 
them to market, this gives rise to the possibility that the intellectual property we seek to acquire has been developed by one of our 
Non-Executive Directors and/or that our Non-Executive Directors provide technical or otherwise specialized advisory services to 
the Company above and beyond the services typically provided by a Non-Executive Director. In such exceptional circumstances, our 
Remuneration Policy provides us with the flexibility to remunerate them with equity in the relevant subsidiary company as we would 
any other inventor of the intellectual property or provider of technical advisory services. This practice is in line with other companies in 
the life sciences sector. If the Company is unable to offer market-competitive remuneration in these circumstances, it risks forfeiting 
opportunities to obtain intellectual property developed by our Non-Executive Directors and/or foregoing valuable advisory services. 
The Company believes foregoing such intellectual property and/or advisory services would not be in the long-term interest of our 
shareholders. Accordingly, subsidiary equity grants may be made to Non-Executive Directors upon the occurrence of the exceptional 
circumstances set out above.

Annual bonus outcome for 2023 (audited)
For the 2023 annual bonus, targets were set for a balanced scorecard at the beginning of the year. The 2023 targets were focused on (i) 
development goals designed to incentivize the team to continue development of the Company’s Internal Programs, generate valuable 
clinical data in support of the Company’s Internal Programs, create innovative Internal Programs, publish key results and achieve patent 
protection for the Company’s Internal Programs; and (ii) strategic goals designed to incentivize the team to complete important deals, 
execute strategic partnerships, monetize Founded Entity holdings or otherwise strengthen the Company’s balance sheet, strengthen 
the Company’s investor base and provide support for Founded Entity transactions and financings. In addition, the Remuneration 
Committee took into account other goals and other achievements by the management team in setting final achievement attainment 
and fixing bonus payouts. The table below sets out the performance assessment and associated bonus outcomes:

Target Goals – Maximum 100 percent Achievement (audited)

Performance Measures Category

Achievement

Internal Program Development 
(50%)

The Internal Program Development Goals were 70 percent achieved in 2023. The 
management team’s performance resulted in an achievement outcome of 35 percent 
which was lower than the pre-specified cap of 50 percent for this category of the goals. 
A description of performance in 2023 is set out below:

Percentage of 
Target Attained

35%

The Company expanded enrollment of Phase 2b multiple ascending dose studies for 
LYT-100 in healthy older adults to support proceeding in IPF, completed studies to support 
appropriate dosing and design of a pivotal trial in IPF, achieved Phase 1b study results 
with LYT-200 and generated data to support the initiation of Phase 2 studies of LYT-200 
in leukemia and solid tumors, completed a Phase 1 study of LYT-300 to select doses for 
a Phase 2 study, nominated LYT-320 as an additional therapeutic candidate, generated 
a key publication in conjunction with a key collaborator and generated several patent 
allowances and issuances in the U.S.

Strategic Goals 
(50%)

The Strategic Goals were 66 percent achieved in 2023. The management team’s performance 
resulted in an achievement outcome of 33 percent out of a pre-specified cap of 50 percent for 
this category of the goals. A description of performance in 2023 is set out below:

33%

The Company extensively evaluated certain strategic transactions and options to enhance 
shareholder value, monetized PureTech’s royalty in Karuna Therapeutics’ KarXT for up to 
$500 million, with $100 million in cash paid up front, considered the further monetization 
of Founded Entity equity holdings and supported its Founded Entities to achieve certain 
strategic transactions, financings and grant funding.

Other Achievements

The management team evidenced further exceptional performance as described below:

7%

The Company completed various strategic sourcing initiatives for new programs and 
strategic transactions, conducted extensive outreach to raise the corporate profile 
and cultivate new investors and analysts, conducted significant and robust activities to 
strengthen the Company’s intellectual property portfolio and generated value accretion 
through the successful activities of certain Founded Entities, especially Karuna in light of 
its sale to Bristol Myers Squibb.

Pre-Specified Maximum Total

75%

Accordingly, the Committee determined that the Company had achieved 75 percent of its target goals for 2023, which would equate to 
a bonus payout at 37.5 percent of base salary. 

Each of the above target categories are subject to maximum percentage achievement limits capped at 100 percent of the target 
bonus (i.e. 50 percent of salary). For 2023, the Committee exercised discretion, increasing the bonus payout to 200 percent of target 
(i.e. 100 percent of base salary) for the reasons set out in the Annual Statement accompanying this report. 

The Committee determined that payouts at this level are appropriate taking into account the overall performance of the Executive 
Directors and the achievements set forth above. In exercising discretion, the Committee also considered the monetization of PureTech’s 
royalty in Karuna Therapeutics’ KarXT for up to $500 million, with $100 million in cash paid up front, and the successful activities of 
certain Founded Entities and the value created for PureTech thereby, especially Karuna in light of its sale to Bristol Myers Squibb. The 
Committee believes that such a bonus award is appropriate to reward and retain top management.

The strategic measures over the three-year period were focused on (i) financial goals (40 percent), (ii) clinical development goals 
(40 percent), and (iii) other achievements (10 percent). The financial achievements resulted in satisfaction of 35 percent of the vesting of 
the strategic measures included, among other things, obtaining approximately $815 million for PureTech by monetizing Founded Entity 
equity, most notably Karuna in light of its sale to Bristol Myers Squibb, the closing of initial public offerings of two Founded Entities and 
two SPAC transactions for Founded Entities, the execution of several partnership agreements which brought in non-dilutive funding 
and the completion of certain investor-related activities. The clinical development achievements resulted in satisfaction of 45 percent 
of the vesting of the strategic measures included, among other things, the successful initiation, enrollment and completion of several 
Phase 1 and Phase 2 clinical studies for LYT-100 and robust enrollment of the LYT-100 IPF phase 2 study, the advancement of other 
product candidates within our Internal Programs, the advancement of certain programs at the Company’s Founded Entities, including 
receipt of U.S. marketing clearances for two programs. The other achievements resulted in satisfaction of 8 percent of the vesting of the 
strategic measures include the monetization of PureTech’s royalty in Karuna Therapeutics’ KarXT for up to $500 million, with $100 million 
in cash paid up front, operation of the Company’s Internal Programs within projected timelines and budgets, conducting significant and 
robust activities to strengthen the Company’s intellectual property portfolio, building out a world-class development organization, the 
in-licensing and creation of new programs, the issuance of certain intellectual property, and the publication of validating data in top tier 
peer-reviewed academic journals.

1  The share price at the date of grant is based on the 3-day average closing price immediately prior to the grant of the award.
2  Share awards have been valued based on an exchange rate of GBP 1: USD 1.2448, which was the 3-day average exchange rate immediately prior to the grant of the award.

The PSP awards granted in 2023 are subject to (i) achievement of absolute TSR targets (40 percent of the awards), (ii) achievement of TSR 
targets as compared to TSR performance of the constituent companies in the FTSE 250 Index (excluding Investment Trusts) and the 
MSCI Europe Health Care Index (20 percent of the awards, 10 percent against each benchmark) and (iii) achievement of targets based on 
strategic measures (40 percent of the awards), measured over the three year period to December 31, 2025.

The minimum performance target for the absolute TSR portion of the award is TSR equal to 7 percent per annum, whilst the maximum 
target is TSR equal to 15 percent per annum. The minimum performance target for the relative TSR portion of the award is TSR equal to 
the median of the index, whilst the maximum target will be TSR equal to the upper quartile of the index. Strategic measures are based 
on the achievement of project milestones and other qualitative measures of performance. Strategic targets have been set based 
on financial achievements, including monetization of Founded Entities, clinical development progress, product pipeline growth, 
operational excellence and other shareholder value enhancing metrics in line with our strategic plan. The Committee believes that this 
combination of measures and the agreed weightings are appropriate. TSR measures the success of our management team in identifying 
and developing new therapeutics whilst strategic targets help incentivize our management team through the stages which ultimately 
result in successful therapeutics.

Full disclosure of the strategic targets will be made retrospectively.

In addition, each Non-Executive Director, with the exception of Mr. Viehbacher, was granted share based remuneration on June 8, 2023, 
in the form of 17,122 time-vesting restricted stock units. The equity awards granted to our Non-Executive Directors vest in their entirety 
immediately prior to Company’s 2024 AGM, provided that the Non-Executive Directors continue their service through such date. This 
share based element is part of the annual fee for Non-Executive Directors and is not subject to performance (audited).

The Remuneration Committee consists of Dr. LaMattina, Ms. Mazumdar-Shaw and Dr. Kucherlapati, with Dr. LaMattina serving as the 
Chair of the Committee. In 2023 the Committee received independent remuneration advice from Korn Ferry (UK) Limited, who was 
appointed by and is accountable to the Committee. A separate practice within Korn Ferry provides certain other candidate placement 
services to the Company. The terms of engagement between the Committee and Korn Ferry are available from the Company Secretary 
on request. The Committee also consults with Executive Directors. However, no Director is permitted to participate in discussions or 
decisions about their personal remuneration. During the year, fees in respect of remuneration advice from Korn Ferry amounted to 
£14,012. Korn Ferry is a founder member of the Remuneration Consultants’ Group and complies with its Code of Conduct which sets 
out guidelines to ensure that its advice is independent and free of undue influence.

Independent auditors’ report to the members 
of PureTech Health plc

Report on the audit of the financial statements

Opinion
In our opinion, PureTech Health plc’s group financial statements 
and company financial statements (the “financial statements”):

 — give a true and fair view of the state of the group’s and of 
the company’s affairs as at 31 December 2023 and of the 
group’s loss and the group’s and company’s cash flows for 
the year then ended;

 — have been properly prepared in accordance with UK-

adopted international accounting standards as applied in 
accordance with the provisions of the Companies Act 2006; 
and

 — have been prepared in accordance with the requirements 

of the Companies Act 2006.

We have audited the financial statements, included within the 
Annual Report and Accounts (the “Annual Report”), which 
comprise: the Consolidated and parent company Statement 
of Financial Position, as at 31 December 2023; Consolidated 
Statement of Comprehensive Income/(Loss), Consolidated and 
parent company Statement of Changes in Equity, Consolidated 
and  parent company Statement of Cash Flows, for the 
year then ended; and the notes to the financial statements, 
comprising material accounting policy information and other 
explanatory information.

Our opinion is consistent with our reporting to the 
Audit Committee.

Separate opinion in relation to IFRSs as issued by the IASB
As explained in note 1 to the financial statements, the group 
and company, in addition to applying UK-adopted international 
accounting standards, have also applied international financial 
reporting standards (IFRSs) as issued by the International 
Accounting Standards Board (IASB).

In our opinion, the group and company financial statements 
have been properly prepared in accordance with IFRSs as 
issued by the IASB.

Basis for opinion
We conducted our audit in accordance with International 
Standards on Auditing (UK) (“ISAs (UK)”) and applicable law. 
Our responsibilities under ISAs (UK) are further described 
in the Auditors’ responsibilities for the audit of the financial 
statements section of our report. We believe that the audit 
evidence we have obtained is sufficient and appropriate to 
provide a basis for our opinion.

Independence
We remained independent of the group in accordance with 
the ethical requirements that are relevant to our audit of the 
financial statements in the UK, which includes the FRC’s Ethical 
Standard, as applicable to listed public interest entities, and 
we have fulfilled our other ethical responsibilities in accordance 
with these requirements.

To the best of our knowledge and belief, we declare that non-
audit services prohibited by the FRC’s Ethical Standard were 
not provided.

Other than those disclosed in Note 8 to the consolidated 
financial statements, we have provided no non-audit services 
to the company or its controlled undertakings in the period 
under audit.

Our audit approach
Context
PureTech Health plc is a public limited company incorporated 
under the laws of England and Wales, and is listed on the FTSE 
Main Market. As such, the group and parent company financial 
statements are subject to an audit in accordance with the 
requirements of the UK Companies Act.

Overview
Audit scope

 — We identified three entities, being PureTech Health LLC, 
PureTech LYT and PureTech LYT 100, Inc, which when 
grouped represent one component, collectively and 
hereafter referred to as PureTech Health. This component, 
in our view, required a full scope audit based on its 
contribution to adjusted loss before tax. In addition, we 
determined that audit procedures over certain accounts 
or balances were required at a further two components 
(Vedanta Biosciences, Inc and Gelesis Holdings, Inc) to 
provide sufficient overall group coverage of particular 
financial statement line items. Further we performed a full 
scope audit under ISA (UK) requirements for the PureTech 
Health plc entity.

 — All work in relation to the components for the group audit 
was performed by our PwC US (overseas supporting firm) 
colleagues in Boston, under our direction and supervision. 
The audit procedures over the parent company were 
performed by PwC UK, in addition to incremental ISA (UK) 
procedures as required for the group audit, which includes 
the audit of the group consolidation.

Key audit matters

 — Determination of the Accounting Treatment for the Sale 

of Future Royalties Liability (group)

 — Valuation of investments in subsidiaries (parent)

Materiality

 — Overall group materiality: $7,000,000 based on 

professional judgement.

 — Overall company materiality: $4,772,000 based on 

1% of total assets.

 — Performance materiality: $5,250,000 (group) and

As part of designing our audit, we determined materiality 
and assessed the risks of material misstatement in the 
financial statements.

Key audit matters
Key audit matters are those matters that, in the auditors’ 
professional judgement, were of most significance in the audit 
of the financial statements of the current period and include 
the most significant assessed risks of material misstatement 
(whether or not due to fraud) identified by the auditors, 
including those which had the greatest effect on: the overall 
audit strategy; the allocation of resources in the audit; and 
directing the efforts of the engagement team. These matters, 
and any comments we make on the results of our procedures 
thereon, were addressed in the context of our audit of the 
financial statements as a whole, and in forming our opinion 
thereon, and we do not provide a separate opinion on 
these matters.

How our audit addressed the key audit matter

Determination of the Accounting Treatment for the Sale of Future 
Royalties Liability (group)

As described in Notes 1 and 17 to the consolidated financial 
statements, on March 4, 2011, the Group entered into a licence 
agreement with Karuna Therapeutics, Inc. (“Karuna”) according to 
which the Group granted Karuna an exclusive licence to research, 
develop and sell KarXT in exchange for a royalty on annual net 
sales, development and regulatory milestones and a fixed portion 
of sublicensing income, if any (hereinafter “Licence Agreement”). 

On March 22, 2023, the Group signed an agreement with Royalty 
Pharma (hereinafter “Royalty Purchase Agreement”), according 
to which the Group sold Royalty Pharma a partial right to receive 
royalty payments made by Karuna in respect of net sales of KarXT, if 
and when received. According to the Royalty Purchase Agreement, 
all royalties due to the Group under the Licence Agreement will be 
paid to Royalty Pharma up until an annual threshold of $60 million, 
while all royalties above such annual threshold in a given year will 
be split 33% to Royalty Pharma and 67% to the Group.

Under the terms of the Royalty Purchase Agreement, the Group 
received a non-refundable initial payment of $100 million at the 
execution of the Royalty Purchase Agreement and is eligible to 
receive additional payments in the aggregate of up to an additional 
$400 million based on the achievement of certain regulatory and 
commercial milestones. The Group continues to hold the rights 
under the Licence Agreement and has a contractual obligation 
to deliver cash to Royalty Pharma for a portion of the royalties 
it receives.

Therefore, the Group will continue to account for any royalties 
and regulatory milestones due to the Group under the License 
Agreement as revenue in its Consolidated Statement of 
Comprehensive Income/(Loss) and record the proceeds from 
the Royalty Purchase Agreement as a financial liability in its 
Consolidated Statement of Financial Position. In determining the 
appropriate accounting treatment for the Royalty Agreement, 
management applied significant judgement. In order to determine 
the amortised cost of the sale of future royalties liability, 
management is required to estimate the total amount of future 
receipts from and payments to Royalty Pharma under the Royalty 
Purchase Agreement over the life of the agreement.

The $100 million liability, recorded at execution of the Royalty 
Purchase Agreement, will be accreted to the total of these receipts 
and payments as interest expense over the life of the Royalty 
Purchase Agreement. The sale of future royalties liability amounted 
to $110.2 million as of December 31, 2023.

Valuation of investments in subsidiaries (parent) 

As described in Note 2 to the parent company financial statements, 
the company holds an investment in its subsidiary undertaking 
($456.9m). The recoverability of the investment is assessed as a 
normal risk, as it is not subject to significant judgement. However 
due to its materiality in the context of the parent company financial 
statements, this is the area which was the key focus of our overall 
parent company audit. Our audit focused on the risk that the 
carrying value of the investment in subsidiaries could be overstated. 
In accordance with IFRS, this asset is subject to impairment testing 
when a triggering event or change in circumstances indicates 
that the carrying value may not be recoverable. Management 
have performed an impairment trigger assessment, and have not 
identified any impairment triggers. No impairment charge has 
been recorded against the company’s investment in subsidiary 
undertakings in the current year.

The principal considerations for our determination that 
performing procedures relating to the determination of 
the accounting treatment for the sale of future royalties 
liability is a critical audit matter are (i) the significant 
judgement by management when determining the 
accounting treatment for the sale of future royalties 
liability and (ii) a high degree of auditor judgement 
and effort in performing procedures and evaluating 
audit evidence related to the accounting for the sale of 
future royalties liability. Addressing the matter involved 
performing procedures and evaluating audit evidence 
in connection with forming our overall opinion on the 
consolidated financial statements. These procedures 
included testing the effectiveness of controls relating 
to management’s determination of the accounting 
treatment for the sale of future royalties liability. 
These procedures also included, among others, (i) 
obtaining and reviewing the key terms of the License 
Agreement and Royalty Agreement; (ii) evaluating the 
appropriateness of management’s determined accounting 
treatment for the sale of future royalties liability; and (iii) 
evaluating the sufficiency of the disclosures within the 
consolidated financial statements. Based on the results 
of the procedures described above, we conclude that 
the accounting treatment for the sale of future royalties 
liability is appropriate.

We evaluated management’s assessment of whether any 
indication of impairment existed, and confirmed that no 
such indication existed. In order to assess whether there is 
an indication of impairment, management compared the 
carrying amount of the net assets of the group ($453.2m) 
to the group’s market capitalisation at December 31, 
2023 of $672.1m. Based on the results of the procedures 
described above, we conclude that the carrying amount 
of the investment in subsidiaries is appropriate. We have 
also assessed the related disclosures in the company only 
financial statements, and consider them to be appropriate.

How we tailored the audit scope
We tailored the scope of our audit to ensure that we performed 
enough work to be able to give an opinion on the financial 
statements as a whole, taking into account the structure of 
the group and the company, the accounting processes and 
controls, and the industry in which they operate.

For each component in the scope of our group audit, we 
allocated a materiality that is less than our overall group 
materiality. The materiality allocated to the component was 
$6,300,000. Certain components were audited to a local 
statutory audit materiality that was also less than our overall 
group materiality.

We tailored the scope of our audit to ensure that we performed 
enough work to be able to give an opinion on the financial 
statements as a whole, taking into account the structure of the 
group and the parent company, the accounting processes and 
controls, and the industry in which they operate. The group’s 
accounting process is structured around a group finance 
function located in Boston, Massachusetts, who maintain 
accounting records and controls for the group.

In establishing the overall group audit strategy and plan, we 
determined whether for each component within the group 
we required an audit of its complete financial information 
(‘full scope audit’), or whether specific audit procedures to 
address a certain risk characteristic or financial statement line 
items would be sufficient. One component, PureTech Health, 
has been considered to be individually financially significant 
and therefore requiring a full scope audit. In addition, we 
determined that audit procedures over certain accounts or 
balances were required at a further two components (Vedanta 
Biosciences, Inc and Gelesis Holdings, Inc) to provide sufficient 
overall group coverage of particular financial statement 
line items. We performed a detailed review of the working 
papers of our overseas supporting firm, and maintained 
regular communications during the planning, execution and 
completion phases of their audit. We directed the work of the 
overseas supporting firm, engaged in site visits, reviewed their 
approach and findings and participated in the closing meetings.

Further we performed a full scope audit under ISA (UK) 
requirements for the PureTech Health plc entity.

The impact of climate risk on our audit
As part of our audit we made enquiries of management and 
performed a risk assessment to consider the potential impacts 
of climate change on the Group and parent company financial 
statements. We remained alert when performing our audit 
procedures for any indicators of the impact of climate risk. Our 
procedures did not identify any material impact as a result of 
climate risk on the group’s and company’s financial statements.

Materiality
The scope of our audit was influenced by our application 
of materiality. We set certain quantitative thresholds for 
materiality. These, together with qualitative considerations, 
helped us to determine the scope of our audit and the nature, 
timing and extent of our audit procedures on the individual 
financial statement line items and disclosures and in evaluating 
the effect of misstatements, both individually and in aggregate 
on the financial statements as a whole.

Based on our professional judgement, we determined 
materiality for the financial statements as a whole as follows:

We use performance materiality to reduce to an appropriately 
low level the probability that the aggregate of uncorrected 
and undetected misstatements exceeds overall materiality. 
Specifically, we use performance materiality in determining 
the scope of our audit and the nature and extent of our testing 
of account balances, classes of transactions and disclosures, 
for example in determining sample sizes. Our performance 
materiality was 75% of overall materiality, amounting to 
$5,250,000 for the group financial statements and $3,579,000 
for the company financial statements.

In determining the performance materiality, we considered 
a number of factors - the history of misstatements, risk 
assessment and aggregation risk and the effectiveness of 
controls – and concluded that an amount in the middle of our 
normal range was appropriate.

We agreed with the Audit Committee that we would report 
to them misstatements identified during our audit above 
$350,000 (group audit) and $239,000 (company audit) as 
well as misstatements below those amounts that, in our view, 
warranted reporting for qualitative reasons.

Conclusions relating to going concern
Our evaluation of the directors’ assessment of the group’s and 
the company’s ability to continue to adopt the going concern 
basis of accounting included:

 — Obtaining from management their assessment which 

supports the Board’s conclusions with respect to going 
concern basis of preparation of the financial statements;

 — Testing the mathematical integrity of the cash flow 

forecasts and the models and reconciled these to the Board 
approved budgets;

 — Identifying and assessing management’s alternate downside 
scenarios, and considering whether the assumptions in the 
downside scenario were reasonable and appropriate;
 — Considering additional mitigating actions, in particular 

assessing the reasonableness of potential mitigating actions 
based on historical execution and feasibility;

 — Assessing the completeness of the going concern 

disclosures; and

 — Assessing the reliability of cash flow forecasts by comparing 
actual performance to forecasts, specifically performing look 
back testing over the budgeted results of 2023.

Based on the work we have performed, we have not identified 
any material uncertainties relating to events or conditions 
that, individually or collectively, may cast significant doubt on 
the group’s and the company’s ability to continue as a going 
concern for a period of at least twelve months from when the 
financial statements are authorised for issue.

Overall materiality

$7,000,000.

How we determined it Based on professional judgement

Rationale for 
benchmark applied

Based on the volatility of earnings experienced by the company 
in recent years, due to material non operating items, we have 
concluded that pre-tax income or loss for the current year alone 
is not the most meaningful benchmark for determining overall 
materiality. Thus, we have also considered adjusted income or loss 
before tax as an alternative benchmark. These benchmarks yielded 
overall materiality levels ranging from $4.8 million to $8 million. 
We then used our professional judgement to determine an overall 
materiality level of $ 7 million.

$4,772,000.

1% of total assets

As the primary value of 
the parent company is the 
investments held, an asset based 
metric is the most appropriate 
benchmark for setting materiality.

Independent auditors’ report to the members of PureTech Health plc continued

In auditing the financial statements, we have concluded that the 
directors’ use of the going concern basis of accounting in the 
preparation of the financial statements is appropriate.

responsibilities with respect to the corporate governance 
statement as other information are described in the Reporting 
on other information section of this report.

However, because not all future events or conditions can be 
predicted, this conclusion is not a guarantee as to the group’s 
and the company’s ability to continue as a going concern.

In relation to the directors’ reporting on how they have 
applied the UK Corporate Governance Code, we have nothing 
material to add or draw attention to in relation to the directors’ 
statement in the financial statements about whether the 
directors considered it appropriate to adopt the going concern 
basis of accounting.

Our responsibilities and the responsibilities of the directors with 
respect to going concern are described in the relevant sections 
of this report.

Reporting on other information
The other information comprises all of the information in the 
Annual Report other than the financial statements and our 
auditors’ report thereon. The directors are responsible for the 
other information. Our opinion on the financial statements 
does not cover the other information and, accordingly, we do 
not express an audit opinion or, except to the extent otherwise 
explicitly stated in this report, any form of assurance thereon.

In connection with our audit of the financial statements, our 
responsibility is to read the other information and, in doing 
so, consider whether the other information is materially 
inconsistent with the financial statements or our knowledge 
obtained in the audit, or otherwise appears to be materially 
misstated. If we identify an apparent material inconsistency or 
material misstatement, we are required to perform procedures 
to conclude whether there is a material misstatement of the 
financial statements or a material misstatement of the other 
information. If, based on the work we have performed, we 
conclude that there is a material misstatement of this other 
information, we are required to report that fact. We have 
nothing to report based on these responsibilities.

With respect to the Strategic report and Directors’ Report, we 
also considered whether the disclosures required by the UK 
Companies Act 2006 have been included.

Based on our work undertaken in the course of the audit, the 
Companies Act 2006 requires us also to report certain opinions 
and matters as described below.

Strategic report and Directors’ Report
In our opinion, based on the work undertaken in the course 
of the audit, the information given in the Strategic report and 
Directors’ Report for the year ended 31 December 2023 is 
consistent with the financial statements and has been prepared 
in accordance with applicable legal requirements.

In light of the knowledge and understanding of the group and 
company and their environment obtained in the course of the 
audit, we did not identify any material misstatements in the 
Strategic report and Directors’ Report.

Directors’ Remuneration
In our opinion, the part of the Directors’ Remuneration Report 
to be audited has been properly prepared in accordance with 
the Companies Act 2006.

Corporate governance statement
The Listing Rules require us to review the directors’ statements 
in relation to going concern, longer-term viability and that 
part of the corporate governance statement relating to the 
company’s compliance with the provisions of the UK Corporate 
Governance Code specified for our review. Our additional 

Based on the work undertaken as part of our audit, we have 
concluded that each of the following elements of the corporate 
governance statement is materially consistent with the financial 
statements and our knowledge obtained during the audit, 
and we have nothing material to add or draw attention to in 
relation to:

 — The directors’ confirmation that they have carried out a 
robust assessment of the emerging and principal risks;
 — The disclosures in the Annual Report that describe those 
principal risks, what procedures are in place to identify 
emerging risks and an explanation of how these are being 
managed or mitigated;

 — The directors’ statement in the financial statements about 

whether they considered it appropriate to adopt the going 
concern basis of accounting in preparing them, and their 
identification of any material uncertainties to the group’s 
and company’s ability to continue to do so over a period 
of at least twelve months from the date of approval of the 
financial statements;

 — The directors’ explanation as to their assessment of the 

group’s and company’s prospects, the period this assessment 
covers and why the period is appropriate; and
 — The directors’ statement as to whether they have a 

reasonable expectation that the company will be able to 
continue in operation and meet its liabilities as they fall due 
over the period of its assessment, including any related 
disclosures drawing attention to any necessary qualifications 
or assumptions.

Our review of the directors’ statement regarding the longer-
term viability of the group and company was substantially less 
in scope than an audit and only consisted of making inquiries 
and considering the directors’ process supporting their 
statement; checking that the statement is in alignment with the 
relevant provisions of the UK Corporate Governance Code; 
and considering whether the statement is consistent with the 
financial statements and our knowledge and understanding of 
the group and company and their environment obtained in the 
course of the audit.

In addition, based on the work undertaken as part of our audit, 
we have concluded that each of the following elements of the 
corporate governance statement is materially consistent with 
the financial statements and our knowledge obtained during 
the audit:

 — The directors’ statement that they consider the 

Annual Report, taken as a whole, is fair, balanced and 
understandable, and provides the information necessary for 
the members to assess the group’s and company’s position, 
performance, business model and strategy;

 — The section of the Annual Report that describes the review 
of effectiveness of risk management and internal control 
systems; and

 — The section of the Annual Report describing the work of the 

Audit Committee.

We have nothing to report in respect of our responsibility to 
report when the directors’ statement relating to the company’s 
compliance with the Code does not properly disclose a 
departure from a relevant provision of the Code specified under 
the Listing Rules for review by the auditors.

Responsibilities for the financial statements and the audit
Responsibilities of the directors for the financial statements
As explained more fully in the Statement of Directors’ 
responsibilities in respect of the Annual Report and the financial 
statements, the directors are responsible for the preparation 

Financial statementsPureTech Health plc   Annual report and accounts 2023    127

Independent auditors’ report to the members of PureTech Health plc continued

of the financial statements in accordance with the applicable 
framework and for being satisfied that they give a true and fair 
view. The directors are also responsible for such internal control 
as they determine is necessary to enable the preparation of 
financial statements that are free from material misstatement, 
whether due to fraud or error.

are not closely related to events and transactions reflected 
in the financial statements. Also, the risk of not detecting a 
material misstatement due to fraud is higher than the risk of 
not detecting one resulting from error, as fraud may involve 
deliberate concealment by, for example, forgery or intentional 
misrepresentations, or through collusion.

In preparing the financial statements, the directors are 
responsible for assessing the group’s and the company’s ability 
to continue as a going concern, disclosing, as applicable, 
matters related to going concern and using the going concern 
basis of accounting unless the directors either intend to 
liquidate the group or the company or to cease operations, or 
have no realistic alternative but to do so.

Auditors’ responsibilities for the audit of the financial statements
Our objectives are to obtain reasonable assurance about 
whether the financial statements as a whole are free from 
material misstatement, whether due to fraud or error, and to 
issue an auditors’ report that includes our opinion. Reasonable 
assurance is a high level of assurance, but is not a guarantee 
that an audit conducted in accordance with ISAs (UK) will always 
detect a material misstatement when it exists. Misstatements 
can arise from fraud or error and are considered material if, 
individually or in the aggregate, they could reasonably be 
expected to influence the economic decisions of users taken on 
the basis of these financial statements.

Irregularities, including fraud, are instances of non-compliance 
with laws and regulations. We design procedures in line 
with our responsibilities, outlined above, to detect material 
misstatements in respect of irregularities, including fraud. 
The extent to which our procedures are capable of detecting 
irregularities, including fraud, is detailed below.

Based on our understanding of the group and industry, we 
identified that the principal risks of non-compliance with 
laws and regulations related to direct laws and regulations 
over financial reporting, specifically Companies Act 2006 
and tax legislation, and we considered the extent to which 
non-compliance might have a material effect on the financial 
statements. We evaluated management’s incentives and 
opportunities for fraudulent manipulation of the financial 
statements (including the risk of override of controls), and 
determined that the principal risks were related to the 
misappropriation of cash. The group engagement team shared 
this risk assessment with the component auditors so that they 
could include appropriate audit procedures in response to such 
risks in their work. Audit procedures performed by the group 
engagement team and/or component auditors included:

 — Identifying and testing of journal entries based on our risk 
assessment criteria, in particular any journals with unusual 
account combinations which credit cash;

 — Evaluation of controls designed to prevent and detect 

irregularities;

 — Reviewing board minutes throughout the financial year 
and post year end to identify any unusual items such as 
suspicious activity, non-compliance, breaches of laws or 
potential litigation;

 — Review of financial statements disclosures for compliance 

with Companies Act 2006;

 — Assessing compliance with the tax legislation through our 

audit work over the payroll, VAT and corporation tax;
 — Performing enquiries of the Directors, management and 
legal counsel and inspection of regulatory and legal 
correspondence and;

 — Incorporating unpredictability into our audit plan.

There are inherent limitations in the audit procedures described 
above. We are less likely to become aware of instances of non-
compliance with laws and regulations that 

Our audit testing might include testing complete populations of 
certain transactions and balances, possibly using data auditing 
techniques. However, it typically involves selecting a limited 
number of items for testing, rather than testing complete 
populations. We will often seek to target particular items for 
testing based on their size or risk characteristics. In other cases, 
we will use audit sampling to enable us to draw a conclusion 
about the population from which the sample is selected.

A further description of our responsibilities for the audit of the 
financial statements is located on the FRC’s website at: www.frc.
org.uk/auditorsresponsibilities. This description forms part of 
our auditors’ report.

Use of this report

only for the company’s members as a body in accordance with 
Chapter 3 of Part 16 of the Companies Act 2006 and for no 
other purpose. We do not, in giving these opinions, accept 
or assume responsibility for any other purpose or to any other 
person to whom this report is shown or into whose hands it 
may come save where expressly agreed by our prior consent 
in writing.

Other required reporting
Companies Act 2006 exception reporting
Under the Companies Act 2006 we are required to report 
to you if, in our opinion:

 — we have not obtained all the information and explanations 

we require for our audit; or

 — adequate accounting records have not been kept by the 

company, or returns adequate for our audit have not been 
received from branches not visited by us; or

 — certain disclosures of directors’ remuneration specified by 

law are not made; or

 — the company financial statements and the part of the 

Directors’ Remuneration Report to be audited are not in 
agreement with the accounting records and returns.

We have no exceptions to report arising from this responsibility.

Appointment
Following the recommendation of the Audit Committee, we 
were appointed by the directors on 13 June 2023 to audit the 
financial statements for the year ended 31 December 2023 and 
subsequent financial periods. This is therefore our first year of 
uninterrupted engagement.

Notes to the Consolidated Financial Statements 

(Amounts in thousands, except share and per share data, or exercise price and conversion price)

1.   Material Accounting Policies

Description of Business
PureTech Health plc (the “Parent”) is a public company incorporated, domiciled and registered in the United Kingdom (“UK”). The 
registered number is 09582467 and the registered address is 13th Floor, One Angel Court, London, EC2R 7HJ, United Kingdom.

The Parent and its subsidiaries are together referred to as the “Group”. The Parent company financial statements present financial 
information about the Parent as a separate entity and not about its Group.

The accounting policies set out below have, unless otherwise stated, been applied consistently to all periods presented in these 
group financial statements.

Basis of Presentation
The consolidated financial statements of the Group (the "Consolidated Financial Statements") are presented as of December 31, 
2023 and 2022, and for the years ended December 31, 2023, 2022 and 2021. The Consolidated Financial Statements have been 
approved by the Directors on April 25, 2024, and are prepared in accordance with UK-adopted International Financial Reporting 
Standards ("IFRSs"). The Consolidated Financial Statements also comply fully with IFRSs as issued by the International Accounting 
Standards Board ("IASB"). UK-adopted IFRSs differs in certain respects from IFRSs as issued by the IASB. However, the differences 
have no impact for the periods presented. 

For presentation of the Consolidated Statement of Comprehensive Income/(Loss), the Group uses a classification based on the 
function of expenses, rather than based on their nature, as it is more representative of the format used for internal reporting and 
management purposes and is consistent with international practice.

Certain amounts in the Consolidated Financial Statements and accompanying notes may not add due to rounding. All percentages 
have been calculated using unrounded amounts.

Basis of Measurement 
The Consolidated Financial Statements are prepared on the historical cost basis except that the following assets and liabilities are 
stated at their fair value: investments held at fair value, investments in notes from associates and liabilities classified as fair value 
through the profit or loss. 

Use of Judgments and Estimates 
In preparing the Consolidated Financial Statements, management has made judgements, estimates and assumptions that affect 
the application of the Group’s accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual 
results may differ from these estimates. Estimates and underlying assumptions are reviewed on an on-going basis.

Significant estimation is applied in determining the following:

 — Financial instruments valuations (see Note 18. Financial Instruments): In accordance with IFRS 9, the Group carries certain 

financial assets and financial liabilities at fair value, with changes in fair value through profit and loss ("FVTPL"). Valuation of 
the aforementioned financial instruments (assets and liabilities) includes making significant estimates, specifically determining 
the appropriate valuation methodology and making certain estimates such as the future expected returns on the financial 
instrument in different scenarios, appropriate discount rate, volatility, and term to exit. 

Significant judgement is also applied in determining the following:

 — Whether financial instruments should be classified as liability or equity (see Note 16. Subsidiary Preferred Shares.). The 

judgement includes an assessment of whether the financial instruments include contractual obligations of the Group to deliver 
cash or other financial assets or to exchange financial assets or financial liabilities with another party, and whether those 
obligations could be settled by the Group exchanging a fixed amount of cash or other financial assets for a fixed number of its 
own equity instruments. Further information about these critical judgements and estimates is included below under Financial 
Instruments.

 — Whether the power to control investees exists (see Note 5. Investments Held at Fair Value and Note 6. Investments in 

Associates and accounting policy with regard to Subsidiaries below). The judgement includes an assessment of whether 
the Group has (i) power over the investee; (ii) exposure, or rights, to variable returns from its involvement with the investee; 
and (iii) the ability to use its power over the investee to affect the amount of its own returns. The Group considers among 
others its voting shares, shareholder agreements, ability to appoint board members, representation on the board, rights to 
appoint management, de facto control, investee dependence on the Group, etc. If the power to control the investee exists, it 
consolidates the financial statements of such investee in the Consolidated Financial Statements of the Group. Upon issuance 
of new shares in an investee and/or a change in any shareholders or governance agreements, the Group reassesses its ability 
to control the investee based on the revised voting interest, revised board composition and revised subsidiary governance and 
management structure. When such new circumstances result in the Group losing its power to control the investee, the investee 
is deconsolidated. On March 1 2023 Vedanta was deconsolidated. Although the Group holds 47% of the voting rights and 
the other shareholders are widely dispersed, the Group does not have de facto control because the investor rights agreement 
stipulates that the relevant activities of Vedanta are directed by Vedanta's Board and the Group does not control Vedanta's 
Board decision making. Voting rights are not the dominant factor for directing Vedanta's relevant activities.

Notes to the Consolidated Financial Statements continued

1.   Accounting policies continued

 — Whether the Group has significant influence over financial and operating policies of investees in order to determine if the 

Group should account for its investment as an associate based on IAS 28 or a financial instrument based on IFRS 9.  (refer to 
Note 5. Investments Held at Fair Value and Note 6. Investments in Associates ). This judgement includes, among others, an 
assessment whether the Group has representation on the board of directors of the investee, whether the Group participates in 
the policy making processes of the investee, whether there is any interchange of managerial personnel, whether there is any 
essential technical information provided to the investee and if there are any transactions between the Group and the investee.

 — Upon determining that the Group does have significant influence over the financial and operating policies of an investee, if 
the Group holds more than a single instrument issued by its equity-accounted investee, judgement is required to determine 
whether the additional instrument forms part of the investment in the associate, which is accounted for under IAS 28 and 
scoped out of IFRS 9, or it is a separate financial instrument that falls in the scope of IFRS 9. This judgement includes an 
assessment of the characteristics of the financial instrument of the investee held by the Group and whether such financial 
instrument provides access to returns underlying an ownership interest.

 — When the Group has other investments in an equity accounted investee that are not accounted for under IAS 28, judgement is 
required in determining if such investments constitute long-term interests ("LTI") for the purposes of IAS 28. This determination 
is based on the individual facts and circumstances and characteristics of each investment, but is driven, among other factors, by 
the intention and likelihood to settle the instrument through redemption or repayment in the foreseeable future, and whether 
or not the investment is likely to be converted to common stock or other equity instruments. After considering the individual 
facts and circumstances of the Group’s investment in its associate's preferred stock in the manner described above, including 
the long-term nature of such investment, the ability of the Group to convert its preferred stock investment to an investment in 
common shares and the likelihood of such conversion, the Group concluded that such investment was considered a long term 
interest.

 — In determining the appropriate accounting treatment for the Royalty Purchase Agreement, management applied significant 

judgement (refer to Note 17. Sale of Future Royalties Liability).

As of December 31, 2023, the Group had cash and cash equivalents of $191,081 and short-term investments of $136,062. 
Considering the Group’s financial position as of December 31, 2023, and its principal risks and opportunities, the Group prepared 
a going concern analysis covering a period of at least the twelve-month period from the date of signing the Consolidated Financial 
Statements ("the going concern period") utilizing realistic scenarios and applying a severe but plausible downside scenario. 
Even under the downside scenario, the analysis demonstrates the Group continues to maintain sufficient liquidity headroom and 
continues to comply with all financial obligations. The Board of Directors believe the Group and the Parent is adequately resourced 
to continue in operational existence for at least the twelve-month period from the date of signing the Consolidated Financial 
Statements. Accordingly, the Board of Directors considered it appropriate to adopt the going concern basis of accounting in 
preparing the Consolidated Financial Statements and the PureTech Health plc Financial Statements. 

Basis of consolidation
The Consolidated Financial Statements as of December 31, 2023 and 2022, and for each of the years ended December 31, 2023, 
2022 and 2021, comprises PureTech Health plc and its consolidated subsidiaries. Intra-group balances and transactions, and any 
unrealized income and expenses arising from intra-group transactions, are eliminated.

Subsidiaries 
As used in these financial statements, the term subsidiaries refers to entities that are controlled by the Group. Under applicable 
accounting rules, the Group controls an entity when it is exposed to, or has the rights to, variable returns from its involvement with 
the entity and has the ability to affect those returns through its power over the entity. In assessing control, the Group takes into 
consideration potential voting rights, board representation, shareholders' agreements, ability to appoint board of directors and 
management, de facto control and other related factors. The financial statements of subsidiaries are included in the Consolidated 
Financial Statements from the date that control commences until the date that control ceases. Losses applicable to the non-
controlling interests in a subsidiary are allocated to the non-controlling interests even if doing so causes the non-controlling 
interests to have a deficit balance.

7  Follica became inactive during 2023.

Change in Subsidiary Ownership and Loss of Control 
Changes in the Group’s interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions.

Where the Group loses control of a subsidiary, the assets and liabilities are derecognized along with any related non-controlling 
interest (“NCI”). Any interest retained in the former subsidiary is measured at fair value when control is lost. Any resulting gain or 
loss is recognized as profit or loss in the Consolidated Statement of Comprehensive Income/(Loss).

Associates 
As used in these financial statements, the term associates are those entities in which the Group has no control but maintains 
significant influence over the financial and operating policies. Significant influence is presumed to exist when the Group holds 
between 20 and 50 percent of the voting power of an entity, unless it can be clearly demonstrated that this is not the case. The 
Group evaluates if it maintains significant influence over associates by assessing if the Group has the power to participate in the 
financial and operating policy decisions of the associate.

Financial statements136    PureTech Health plc   Annual report and accounts 2023

Notes to the Consolidated Financial Statements continued

1.   Accounting policies continued

Application of the Equity Method to Associates 
Associates are accounted for using the equity method (equity accounted investees) and are initially recognized at cost, or if 
recognized upon deconsolidation, they are initially recorded at fair value at the date of deconsolidation. The Consolidated 
Financial Statements include the Group’s share of the total comprehensive income or loss of equity accounted investees, from the 
date that significant influence commences until the date that significant influence ceases. 

To the extent the Group holds interests in associates that are not providing access to returns underlying ownership interests, the 
instrument is accounted for in accordance with IFRS 9 as investments held at fair value.

When the Group’s share of losses exceeds its equity method investment in the investee, losses are applied against long-term 
interests, which are investments accounted for under IFRS 9. Investments are determined to be long-term interests when they 
are long-term in nature and in substance they form part of the Group's net investment in that associate. This determination is 
impacted by many factors, among others, whether settlement by the investee through redemption or repayment is planned or 
likely in the foreseeable future, whether the investment can be converted and/or is likely to be converted to common stock or 
other equity instrument and other factors regarding the nature of the investment. Whilst this assessment is dependent on many 
specific facts and circumstances of each investment, typically conversion features whereby the investment is likely to convert 
to common stock or other equity instruments would point to the investment being a long-term interest. Similarly, where the 
investment is not planned or likely to be settled through redemption or repayment in the foreseeable future, this would indicate 
that the investment is a long-term interest. When the net investment in the associate, which includes the Group’s investments in 
other long-term interests, is reduced to nil, recognition of further losses is discontinued except to the extent that the Group has 
incurred legal or constructive obligations or made payments on behalf of an investee.

The Group has adopted the amendments to IAS 28 Investments in Associates that addresses the dual application of IAS 28 and 
IFRS 9 when equity method losses are applied against long-term interests. The amendments provide the annual sequence in 
which both standards are to be applied in such a case. The Group has applied the equity method losses to the long-term interests 
presented as part of Investments held at fair value subsequent to remeasuring such investments to their fair value at balance sheet 
date.

Sale of Future Royalties Liability
The Group accounts for the sale of future royalties liability as a financial liability, as it continues to hold the rights under the royalty 
bearing licensing agreement and has a contractual obligation to deliver cash to an investor for a portion of the royalty it receives. 
Interest on the sale of future royalties liability is recognized using the effective interest rate over the life of the related royalty 
stream.

The sale of future royalties liability and the related interest expense are based on the Group’s current estimates of future royalties 
expected to be paid over the life of the arrangement. Forecasts are updated periodically as new data is obtained. Any increases, 
decreases or a shift in timing of estimated cash flows require the Group to re-calculate the amortized cost of the sale of future 
royalties liability as the present value of the estimated future contractual cash flows that are discounted at the liability’s original 
effective interest rate. The adjustment is recognized immediately in profit or loss as income or expense.

Financial Instruments 
Classification 
The Group classifies its financial assets in the following measurement categories:

 — Those to be measured subsequently at fair value either through other comprehensive income "FVOCI", or through profit or loss 

"FVTPL", and

 — Those to be measured at amortized cost.

The classification depends on the Group’s business model for managing the financial assets and the contractual terms of the cash 
flows.

For assets measured at fair value, gains and losses are recorded in profit or loss. 

Measurement 
At initial recognition, the Group measures a financial asset at its fair value plus, in the case of a financial asset not at FVTPL, 
transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets that are 
carried at FVTPL are expensed.

Impairment 
The Group assesses on a forward-looking basis the expected credit losses associated with its debt instruments carried at amortized 
cost. For trade receivables, the Group applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses 
to be recognized from initial recognition of the receivables.

Financial Assets 
The Group’s financial assets consist of cash and cash equivalents, investments in debt securities, trade and other receivables, 
notes, restricted cash deposits and investments in equity securities. The Group’s financial assets are virtually all classified into the 
following categories: investments held at fair value, notes, trade and other receivables, short-term investments and cash and cash 
equivalents. The Group determines the classification of financial assets at initial recognition depending on the purpose for which 
the financial assets were acquired.

Investments held at fair value are investments in equity instruments. Such investments consist of the Group's minority interest 
holdings where the Group has no significant influence or preferred share investments that are not providing access to returns 
underlying ownership interests and are categorized as debt instruments that are presented at fair value through profit and loss 
because the amounts receivable do not represent solely payments of principal and interest. These financial assets are initially 
measured at fair value and subsequently re-measured at fair value at each reporting date.  The  Group has elected to record the 
changes in fair values for the financial assets falling under this category through profit and loss. Please refer to Note 5. Investments 
Held at Fair Value.

Financial statementsPureTech Health plc   Annual report and accounts 2023    137

Notes to the Consolidated Financial Statements continued

1.   Accounting policies continued

Changes in the fair value of financial assets at FVTPL are recognized in other income/(expense) in the Consolidated Statement of 
Comprehensive Income/(Loss) as applicable. 

The notes from an associate, since their contractual terms do not consist solely of cash flow payments of principal and interest 
on the principal amount outstanding, are initially and subsequently measured at fair value, with changes in fair value recognized 
through profit and loss.

Cash and cash equivalents consist of demand deposits with banks and other financial institutions and highly liquid instruments 
with original maturities of three months or less at the date of purchase. Cash and cash equivalents are carried at cost, which 
approximates their fair value.

Short-term investments consist of short-term US treasury bills that are held to maturity. The contractual terms consist solely of 
payment of the principal and interest and the Group's business model is to hold the treasury bills to maturity. As such, such short-
term investments are recorded at amortized cost. As of balance sheet date, amortized cost approximated the fair value of such 
short-term investments.

Trade and other receivables are non-derivative financial assets with fixed and determinable payments that are not quoted on 
active markets. These financial assets are carried at the amounts expected to be received less any expected lifetime losses. Such 
losses are determined taking into account previous experience, credit rating and economic stability of counterparty and economic 
conditions. When a trade receivable is determined to be uncollectible, it is written off against the available provision. As of balance 
sheet date, the Group did not record any such expected lifetime losses related to the outstanding trade and other receivable 
balances. Trade and other receivables are included in current assets, unless maturities are greater than 12 months after the end of 
the reporting period.

Financial Liabilities 
The Group’s financial liabilities primarily consist of trade and other payables, and preferred shares. 

The majority of the Group’s subsidiaries have preferred shares and certain notes payable with embedded derivatives, which 
are classified as current liabilities. When the Group has preferred shares and notes with embedded derivatives that qualify 
for bifurcation, the Group has elected to account for the entire instrument as FVTPL after determining under IFRS 9 that the 
instrument qualifies to be accounted for under such FVTPL method.

The Group derecognizes a financial liability when its contractual obligations are discharged, cancelled or expire.

Equity Instruments Issued by the Group 
Financial instruments issued by the Group are treated as equity only to the extent that they meet the following two conditions, in 
accordance with IAS 32:

1.  They include no contractual obligations upon the Group to deliver cash or other financial assets or to exchange financial assets 

or financial liabilities with another party under conditions that are potentially unfavorable to the Group; and

2.  Where the instrument will or may be settled in the Group’s own equity instruments, it is either a non-derivative that includes no 
obligation to deliver a variable number of the Group’s own equity instruments or is a derivative that will be settled by the Group 
exchanging a fixed amount of cash or other financial assets for a fixed number of its own equity instruments.

To the extent that this definition is not met, the financial instrument is classified as a financial liability. Where the instrument so 
classified takes the legal form of the Group’s own shares, the amounts presented in the Group's shareholders' equity exclude 
amounts in relation to those shares.

Changes in the fair value of liabilities at FVTPL are recognized in net finance income /(costs) in the Consolidated Statement of 
Comprehensive Income/(Loss) as applicable. 

IFRS 15, Revenue from Contracts with Customers 
The standard establishes a five-step principle-based approach for revenue recognition and is based on the concept of recognizing 
an amount that reflects the consideration for performance obligations only when they are satisfied and the control of goods or 
services is transferred.

The majority of the Group’s contract revenue is generated from licenses and services, some of which are part of collaboration 
arrangements. 

Management reviewed contracts where the Group received consideration in order to determine whether or not they should be 
accounted for in accordance with IFRS 15. To date, the Group has entered into transactions that generate revenue and meet the 
scope of either IFRS 15 or IAS 20 Accounting for Government Grants. Contract revenue is recognized at either a point-in-time or 
over time, depending on the nature of the performance obligations.

The Group accounts for agreements that meet the definition of IFRS 15 by applying the following five step model:

 — Identify the contract(s) with a customer – A contract with a customer exists when (i) the Group enters into an enforceable 

contract with a customer that defines each party’s rights regarding the goods or services to be transferred and identifies the 
payment terms related to those goods or services, (ii) the contract has commercial substance and, (iii) the Group determines 
that collection of substantially all consideration for goods or services that are transferred is probable based on the customer’s 
intent and ability to pay the promised consideration.

 — Identify the performance obligations in the contract – Performance obligations promised in a contract are identified based on 

the goods or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can 
benefit from the good or service either on its own or together with other resources that are readily available from third parties 
or from the Group, and are distinct in the context of the contract, whereby the transfer of the goods or services is separately 
identifiable from other promises in the contract.

Financial statements138    PureTech Health plc   Annual report and accounts 2023

Notes to the Consolidated Financial Statements continued

1.   Accounting policies continued

 — Determine the transaction price – The transaction price is determined based on the consideration to which the Group will 
be entitled in exchange for transferring goods or services to the customer. To the extent the transaction price includes 
variable consideration, the Group estimates the amount of variable consideration that should be included in the transaction 
price utilizing either the expected value method or the most likely amount method depending on the nature of the variable 
consideration. Variable consideration is included in the transaction price if, in the Group’s judgement, it is probable that a 
significant future reversal of cumulative revenue under the contract will not occur. 

 — Allocate the transaction price to the performance obligations in the contract – If the contract contains a single performance 
obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple 
performance obligations require an allocation of the transaction price to each performance obligation based on a relative 
standalone selling price basis. 

 — Recognize revenue when (or as) the Group satisfies a performance obligation – The Group satisfies performance obligations 
either over time or at a point in time as discussed in further detail below. Revenue is recognized at the time the related 
performance obligation is satisfied by transferring a promised good or service to a customer.

Revenue generated from services agreements (typically where licenses and related services were combined into one performance 
obligation) is determined to be recognized over time when it can be determined that the services meet one of the following: (a) 
the customer simultaneously receives and consumes the benefits provided by the entity’s performance as the entity performs; 
(b) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced; or (c) 
the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to 
payment for performance completed to date.

It was determined that the Group has contracts that meet criteria (a), since the customer simultaneously receives and consumes 
the benefits provided by the Group’s performance as the Group performs. Therefore revenue is recognized over time using 
the input method based on costs incurred to date as compared to total contract costs. The Group believes that in research 
and development service type agreements using costs incurred to date represents the most faithful depiction of the entity’s 
performance towards complete satisfaction of a performance obligation.

Revenue from licenses that are not part of a combined performance obligation are recognized at a point in time due to the 
licenses relating to intellectual property that has significant stand-alone functionality and as such represent a right to use the 
entity's intellectual property as it exists at the point in time at which the license is granted.

Royalty income received in respect of licensing agreements when the license of intellectual property is the predominant item in the 
arrangement is recognized as the related third-party sales in the licensee occur.

Amounts that are receivable or have been received per contractual terms but have not been recognized as revenue since 
performance has not yet occurred or has not yet been completed are recorded as deferred revenue. The Group classifies as non-
current deferred revenue amounts received for which performance is expected to occur beyond one year or one operating cycle.

Grant Revenue
The Group recognizes grants from governmental agencies as grant revenue in the Consolidated Statement of Comprehensive 
Income/(Loss), gross of the expenditures that were related to obtaining the grant, when there is reasonable assurance that the 
Group will comply with the conditions within the grant agreement and there is reasonable assurance that payments under the 
grants will be received. The Group evaluates the conditions of each grant as of each reporting date to ensure that the Group has 
reasonable assurance of meeting the conditions of each grant arrangement and that it is expected that the grant payment will be 
received as a result of meeting the necessary conditions.

The  Group submits qualifying expenses for reimbursement after the Group has incurred the research and development expense. 
The Group records an unbilled receivable upon incurring such expenses. In cases in which the grant revenue is received prior 
to the expenses being incurred or recognized, the amounts received are deferred until the related expense is incurred and/or 
recognized. Grant revenue is recognized in the Consolidated Statement of Comprehensive Income/(Loss) at the time in which the 
Group recognizes the related reimbursable expense for which the grant is intended to compensate.

Functional and Presentation Currency 
The Consolidated Financial Statements are presented in United States dollars (“US dollars”). The functional currency of all 
members of the Group is the U.S. dollar.  The Group's share in foreign exchange differences in associates were reported in other 
comprehensive income/(loss).

Foreign Currency 
Transactions in foreign currencies are translated to the respective functional currencies of Group entities at the foreign exchange 
rate ruling at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies at the balance sheet 
date are retranslated to the functional currency at the foreign exchange rate ruling at that date. Foreign exchange differences 
arising on remeasurement are recognized in the Consolidated Statement of Comprehensive Income/(Loss). Non-monetary assets 
and liabilities that are measured in terms of historical cost in a foreign currency are translated using the exchange rate at the date 
of the transaction. 

Share Capital 
Ordinary shares are classified as equity. The Group's equity is comprised of share capital, share premium, merger reserve, other 
reserve, translation reserve, and retained earnings/accumulated deficit.

Financial statementsPureTech Health plc   Annual report and accounts 2023    139

Notes to the Consolidated Financial Statements continued

1.   Accounting policies continued

Treasury Shares
Treasury shares are recognized at cost and are deducted from shareholders' equity. No gain or loss is recognized in profit and loss 
for the purchase, sale, re-issue or cancellation of the Group's own equity shares.

Property and Equipment 
Property and equipment is stated at cost less accumulated depreciation and any accumulated impairment losses. Cost includes 
expenditures that are directly attributable to the acquisition of the asset. Assets under construction represent leasehold 
improvements and machinery and equipment to be used in operations or research and development activities. When parts of 
an item of property and equipment have different useful lives, they are accounted for as separate items (major components) of 
property and equipment. Depreciation is calculated using the straight-line method over the estimated useful life of the related 
asset: 

Laboratory and manufacturing equipment
Furniture and fixtures
Computer equipment and software
Leasehold improvements

2-8 years
7 years
1-5 years
5-10 years, or the remaining term of the lease, if shorter

Depreciation methods, useful lives and residual values are reviewed at each balance sheet date.

Intangible Assets 
Intangible assets, which include purchased patents and licenses with finite useful lives, are carried at historical cost less 
accumulated amortization, if amortization has commenced. Intangible assets with finite lives are amortized from the time they 
are available for their intended use. Amortization is calculated using the straight-line method to allocate the costs of patents and 
licenses over their estimated useful lives. 

Research and development intangible assets, which are still under development and have accordingly not yet obtained marketing 
approval, are presented as In-Process Research and Development (IPR&D). The cost of IPR&D represents upfront payments as well 
as additional contingent payments based on development, regulatory and sales milestones related to certain license agreement 
where the Group licenses IP from a third party. These milestones are capitalized as the milestone is triggered. See Note 25. 
Commitments and Contingencies. IPR&D is not amortized since it is not yet available for its intended use, but it is evaluated for 
potential impairment on an annual basis or more frequently when facts and circumstances warrant.

Impairment of Non-Financial Assets 
The Group reviews the carrying amounts of its property and equipment and intangible assets at each reporting date to determine 
whether there are indicators of impairment. If any such indicators of impairment exist, then an asset’s recoverable amount is 
estimated. The recoverable amount is the higher of an asset’s fair value less cost of disposal and value in use.

The Group’s IPR&D intangible assets are not yet available for their intended use. As such, they are tested for impairment at least 
annually. 

An impairment loss is recognized when an asset’s carrying amount exceeds its recoverable amount. For the purposes of 
impairment testing, assets are grouped at the lowest levels for which there are largely independent cash flows. If a non- financial 
asset instrument is impaired, an impairment loss is recognized in the Consolidated Statement of Comprehensive Income/(Loss).

Investments in associates are considered impaired if, and only if, objective evidence indicates that one or more events, which 
occurred after the initial recognition, have had an impact on the future cash flows from the net investment and that impact can 
be reliably estimated. If an impairment exists, the Group measures an impairment by comparing the carrying value of the net 
investment in the associate to its recoverable amount and recording any excess as an impairment loss. See Note 6. Investments in 
Associates for impairment recorded in respect of an investment in associate during the year ended December 31, 2022.

Employee Benefits 
Short-Term Employee Benefits 
Short-term employee benefit obligations are measured on an undiscounted basis and expensed as the related service is provided. 
A liability is recognized for the amount expected to be paid if the Group has a present legal or constructive obligation due to past 
service provided by the employee, and the obligation can be estimated reliably.

Defined Contribution Plans 
A defined contribution plan is a post-employment benefit plan under which an entity pays fixed contributions into a separate entity 
and has no legal or constructive obligation to pay further amounts. Obligations for contributions to defined contribution plans are 
recognized as an employee benefit expense in the periods during which related services are rendered by employees. 

Share-based Payments 
Share-based payment arrangements, in which the Group receives goods or services as consideration for its own equity 
instruments, are accounted for as equity-settled share-based payment transactions (except certain restricted stock units – see 
below) in accordance with IFRS 2, regardless of how the equity instruments are obtained by the Group. The grant date fair value 
of employee share-based payment awards is recognized as an expense with a corresponding increase in equity over the requisite 
service period related to the awards. The amount recognized as an expense is adjusted to reflect the actual number of awards 
for which the related service and non-market performance conditions are expected to be met, such that the amount ultimately 
recognized as an expense is based on the number of awards that do meet the related service and non-market performance 
conditions at the vesting date. For share-based payment awards with market conditions, the grant date fair value is measured to 
reflect such conditions and there is no true-up for differences between expected and actual outcomes.

Certain restricted stock units are treated as liability settled awards starting in 2021. Such awards are remeasured at every 
reporting date until settlement date and are recognized as compensation expense over the requisite service period. Differences in 
remeasurement are recognized in profit and loss. The cumulative cost that will ultimately be recognized in respect of these awards 
will equal to the amount at settlement. 

The fair value of the awards is measured using option pricing models and other appropriate models, which take into account the 
terms and conditions of the awards granted. 

Development Costs 
Expenditures on research activities are recognized as incurred in the Consolidated Statement of Comprehensive Income/(Loss). 
In accordance with IAS 38, development costs are capitalized only if the expenditure can be measured reliably, the product or 
process is technically and commercially feasible, future economic benefits are probable, the Group can demonstrate its ability 
to use or sell the intangible asset, the Group intends to and has sufficient resources to complete development and to use or 
sell the asset, and it is able to measure reliably the expenditure attributable to the intangible asset during its development. The 
point at which technical feasibility is determined to have been reached is, generally, when regulatory approval has been received 
where applicable. Management determines that commercial viability has been reached when a clear market and pricing point 
have been identified, which may coincide with achieving meaningful recurring sales. Otherwise, the development expenditure is 
recognized as incurred in the Consolidated Statement of Comprehensive Income/(Loss). As of balance sheet date, the Group has 
not capitalized any development costs.

Provisions 
A provision is recognized in the Consolidated Statement of Financial Position when the Group has a present legal or constructive 
obligation due to a past event that can be reliably measured, and it is probable that an outflow of economic benefits will be 
required to settle the obligation. Provisions are determined by discounting the expected future cash flows at a pre-tax rate that 
reflects risks specific to the liability.

Leases
The Group leases real estate for use in operations. These leases have lease terms of approximately 10 years. The Group includes 
options that are reasonably certain to be exercised as part of the determination of the lease term. The group determines if an 
arrangement is a lease at inception of the contract in accordance with guidance detailed in IFRS 16. Right-of-use (ROU) assets 
represent the Group’s right to use an underlying asset for the lease term and lease liabilities represent the Group's obligation to 
make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement 
date based on the present value of the lease payments over the lease term. As most of the Group's leases do not provide an 
implicit rate, the Group used its estimated incremental borrowing rate, based on information available at commencement date, in 
determining the present value of future payments. 

The Group’s leases are virtually all leases of real estate.

The Group has elected to account for lease payments as an expense on a straight-line basis over the life of the lease for: 

 — Leases with a term of 12 months or less and containing no purchase options; and 
 — Leases where the underlying asset has a value of less than $5,000. 

The right-of-use asset is depreciated on a straight-line basis and the lease liability gives rise to an interest charge. 

Finance Income and Finance Costs 
Finance income consists of interest income on funds invested in money market funds and U.S. treasuries. Finance income is 
recognized as it is earned. Finance costs consist mainly of loan, notes and lease liability interest expenses, interest expense due to 
accretion of and adjustment to sale of future royalties liability as well as the changes in the fair value of financial liabilities carried at 
FVTPL (such changes can consist of finance income when the fair value of such financial liabilities decreases).

Taxation 
Tax on the profit or loss for the year comprises current and deferred income tax. In accordance with IAS 12, tax is recognized in the 
Consolidated Statement of Comprehensive Income/(Loss) except to the extent that it relates to items recognized directly in equity.

Current income tax is the expected tax payable or receivable on the taxable income or loss for the year, using tax rates enacted or 
substantially enacted at the reporting date, and any adjustment to tax payable in respect of previous years.

Deferred tax is recognized due to temporary differences between the carrying amounts of assets and liabilities for financial 
reporting purposes and the amounts used for taxation purposes. Deferred tax assets are recognized for unused tax losses, unused 
tax credits and deductible temporary differences to the extent that it is probable that future taxable profits will be available against 
which they can be used. Deferred tax assets with respect to investments in associates are recognized only to the extent that it 
is probable the temporary difference will reverse in the foreseeable future and taxable profit will be available against which the 
temporary difference can be utilized. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it 
is no longer probable that the related tax benefit will be realized.

Financial statementsPureTech Health plc   Annual report and accounts 2023    141

Notes to the Consolidated Financial Statements continued

1.   Accounting policies continued

Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, using tax 
rates enacted or substantively enacted at the reporting date.

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against 
current tax liabilities and when the deferred income tax assets and liabilities relate to income taxes levied by the same taxation 
authority on either the same taxable entity or different taxable entities where there is an intention to settle the balances on a net 
basis.

Fair Value Measurements 
The Group’s accounting policies require that certain financial assets and certain financial liabilities be measured at their fair value.

The Group uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to 
measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. Fair values 
are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows:

 — Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities.
 — Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e. as 

prices) or indirectly (i.e. derived from prices).

 — Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs).

The Group recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the 
change has occurred.

The carrying amount of cash and cash equivalents, accounts receivable, restricted cash, deposits, accounts payable, accrued 
expenses and other current liabilities in the Group’s Consolidated Statement of Financial Position approximates their fair value 
because of the short maturities of these instruments. 

Operating Segments 
Operating segments are reported in a manner that is consistent with the internal reporting provided to the chief operating 
decision maker (“CODM”). The CODM reviews discrete financial information for the operating segments in order to assess their 
performance and is responsible for making decisions about resources allocated to the segments. The CODM has been identified 
as the Group’s Board of Directors.

2.   New Standards and Interpretations

The Group has applied the following amendments for the first time for its annual reporting period commencing January 1, 2023:

 — IFRS 17 Insurance Contracts 
 — Definition of Accounting Estimates (Amendments to IAS 8)
 — Deferred Tax related to Assets and Liabilities Arising from a Single Transaction (Amendments to IAS 12)

The amendments listed above did not have any impact on the amounts recognized in prior and current periods and are not 
expected to significantly affect the future periods.

Certain new accounting standards, amendments to accounting standards and interpretations have been published that are 
not mandatory for December 31, 2023 reporting periods and have not been early adopted by the Group. These standards, 
amendments or interpretations are not expected to have a material impact on the Group in the current or future reporting periods 
and on foreseeable future transactions.

All amounts recorded in contract revenue were generated in the United States. 

For the years ended  December 31, 2023, 2022 and 2021, contract revenue includes royalties received from an associate in the 
amounts of zero, $509 and  $231, respectively.

Substantially all of the Group’s  contracts related to contract revenue for the years ended December 31, 2023, 2022 and 2021 were 
determined to have a single performance obligation which consists of a combined deliverable of license of intellectual property 
and research and development services. Therefore, for such contracts, revenue is recognized over time based on the input method 
which the Group believes is a faithful depiction of the transfer of goods and services. Progress is measured based on costs incurred 
to date as compared to total projected costs. Payments for such contracts are primarily made up-front on a periodic basis.

During the year ended December 31, 2021, the Group received a $6,500 payment from Imbrium Therapeutics, Inc. following the 
exercise of the option to acquire an exclusive license for the Initial Product Candidate, as defined in the agreement. Since the 
license transferred was a right to use license, revenue from the option exercise was recognized at a point in time upon transfer of 
the license, which occurred during the year ended December 31, 2021.

Disaggregated Revenue
The Group disaggregates contract revenue in a manner that depicts how the nature, amount, timing, and uncertainty of revenue 
and cash flows are affected by economic factors. The Group disaggregates revenue based on contract revenue or grant revenue, 
and further disaggregates contract revenue based on the transfer of control of the underlying performance obligations.

Accounts receivables represent rights to consideration in exchange for products or services that have been transferred by the 
Group, when payment is unconditional and only the passage of time is required before payment is due. Accounts receivables do 
not bear interest and are recorded at the invoiced amount. Accounts receivables are included within trade and other receivables 
on the Consolidated Statement of Financial Position. The accounts receivables related to contract revenue were $555 and $606 as 
of December 31, 2023 and 2022, respectively.

4.  Segment Information

Basis for Segmentation 
The Directors are the Group’s chief operating decision-makers. The Group’s operating segments are determined based on the 
financial information provided to the Board of Directors periodically for the purposes of allocating resources and assessing 
performance. During the second half of 2023, the Group changed the financial information that was regularly reviewed by the 
Board of Directors to allocate resources and assess performance. The Group has determined each of its Wholly-Owned Programs 
represents an operating segment and the Group has aggregated each of these operating segments into one reportable segment, 
the Wholly-Owned Programs segment, given the high level of operational and financial similarities across its Wholly-Owned 
Programs. Each of the Group’s Controlled Founded Entities represents an operating segment. The Group aggregates each 
Controlled Founded Entity operating segment into one reportable segment, the Controlled Founded Entities segment. For the 
Group’s entities that do not meet the definition of an operating segment, the Group presents this information in the Parent & 
Other column in its segment footnote to reconcile the information in this footnote to the Consolidated Financial Statements. 
Substantially all of the Group’s revenue and profit generating activities are generated within the United States and, accordingly, no 
geographical disclosures are provided. 

The Group has retroactively recast its fiscal year 2022 and 2021 results on the new basis for comparability.

Following is the description of the Group's reportable segments:

Wholly-Owned Programs
The Wholly-Owned Programs segment is advancing Wholly-Owned Programs which are focused on treatments for patients with 
devastating diseases. The Wholly-Owned Programs segment is comprised of the technologies that are wholly-owned and will 
be advanced through with either the Group's funding or non-dilutive sources of financing. The operational management of the 
Wholly-Owned Programs segment is conducted by the PureTech Health team, which is responsible for the strategy, business 
development, and research and development. 

Controlled Founded Entities
The Controlled Founded Entities segment is comprised of the Group’s consolidated operational subsidiaries as of December 31, 
2023 that either have, or have plans to hire, independent management teams and currently have already raised third-party dilutive 
capital. These subsidiaries have active research and development programs and either have entered into or plan to seek an equity 
or debt investment partner, who will provide additional industry knowledge and access to networks, as well as additional funding 
to continue the pursued growth of the entity. 

The Group’s entities that were determined not to meet the definition of an operating segment are included in the Parent Company 
and Other column to reconcile the information in this footnote to the financial statements. This column captures activities not 
directly attributable to the Group's operating segments and includes the activities of the Parent, corporate support functions and 
certain research and development support functions that are not directly attributable to a strategic business segment as well as the 
elimination of intercompany transactions. This column also captures the operating results for the deconsolidated entities through 
the date of deconsolidation (e.g. Vedanta in 2023 and Sonde in 2022) and accounting for the Group's holdings in Founded Entities 
for which control has been lost, which primarily represents: the activity associated with deconsolidating an entity when the Group 
no longer controls the entity (e.g. Vedanta in 2023 and Sonde in 2022), the gain or loss on the Group's investments accounted 
for at fair value (e.g. the Group's ownership stakes in Karuna, Vor and Akili) and the Group's net income or loss of associates 
accounted for using the equity method. 

(The term "Founded Entities" refers to entities which the Company incorporated and announced the incorporation as a Founded 
Entity externally. It includes certain of the Company’s wholly-owned subsidiaries which have been announced by the Company as 
Founded Entities, Controlled Founded Entities and deconsolidated Founded Entities.)

In January 2024, the Group launched two new Founded Entities to advance certain programs from the Wholly-Owned Programs 
segment. Refer to Note 28. Subsequent Events for detail. The financial results of these programs were included in the Wholly-
Owned Programs segment as of December 31, 2023 and 2022 and for the three years ended December 31, 2023, 2022 and 2021, 
respectively. Upon raising dilutive third-party financing, the financial results of these two entities will be included in the Controlled 
Founded Entities segment to the extent that the Group maintains control over these entities.

The Group’s Board of Directors reviews segment performance and allocates resources based upon revenue and operating loss as 
well as the funds available for each segment. The Board of Directors do not review any other information for purposes of assessing 
segment performance or allocating resources.

5.   Investments Held at Fair Value continued

Vedanta
On March 1, 2023, Vedanta issued convertible debt to a syndicate of investors. The Group did not participate in this round of 
financing. As part of the issuance of the debt, the convertible debt holders were granted representation on Vedanta's Board of 
Directors and the Group lost control over the Vedanta Board of Directors and the power to direct the relevant Vedanta activities. 
Consequently, Vedanta was deconsolidated on March 1, 2023 and its results of operations are included in the Consolidated 
Financial Statements through the date of deconsolidation.

Following deconsolidation, the Group has significant influence over Vedanta through its voting interest in Vedanta and its 
remaining representation on Vedanta's Board of Directors. However, the Group only holds convertible preferred shares in Vedanta 
that do not provide their holders with access to returns associated with a residual equity interest, and as such are accounted for 
under IFRS 9, as investments held at fair value with changes in fair value recorded in profit and loss. Under IFRS 9, the preferred 
share investments are categorized as debt instruments that are presented at fair value through profit and loss because the amounts 
receivable do not represent solely payments of principal and interest.

Upon deconsolidation, the Group derecognized its assets, liabilities and non-controlling interest in respect of Vedanta and 
recorded its aforementioned investment in Vedanta at fair value. The deconsolidation resulted in a gain of $61,787. As of the date 
of deconsolidation, the investment in Vedanta convertible preferred shares held at fair value amounted to $20,456.

During the year ended December 31, 2023, the Group recognized a loss of $6,303 for the changes in the fair value of the 
investment in Vedanta that was included in gain/(loss) on investments held at fair value within the Consolidated Statement of 
Comprehensive Income/(Loss). The fair value of the Group’s investment in Vedanta is $14,153 as of December 31, 2023. 

Karuna
Karuna was deconsolidated in March 2019. During 2019, Karuna completed its IPO and the Group lost its significant influence in 
Karuna. The shares held in Karuna are accounted for as an investment held at fair value under IFRS 9.

2021
On February 9, 2021, the Group sold 1,000,000 common shares of Karuna for $118,000. On November 9, 2021, the Group sold 
an additional 750,000 common shares of Karuna for $100,125. As a result of the aforementioned sales, the Group recorded a loss 
of $20,925, attributable to blockage discount included in the sales price, in realized gain/(loss) on sale of investments within the 
Consolidated Statement of Comprehensive Income/(Loss).

2022
On August 8, 2022, the Group sold 125,000 shares of Karuna common stock. In addition, the Group wrote a series of call options 
entitling the holders thereof to purchase up to 477,100 Karuna common stock at a set price, which were exercised in full in August 
and September 2022. Aggregate proceeds to the Group from all aforementioned transactions amounted to  $115,457, net of 
transaction fees. As a result of the aforementioned sales, the Group recorded a loss of $29,303, attributable to the exercise of the 
aforementioned call options, in realized gain/(loss) on sale of investment within the Consolidated Statement of Comprehensive 
Income/(Loss). 

2023
During the three months ended December 31, 2023, the Group sold 167,579 shares of Karuna common stock with aggregate 
proceeds of $33,309, net of transaction fees. 

During the years ended December 31, 2023, 2022, and 2021 the Group recorded gains of $107,079, $134,952, $109,987, 
respectively for the changes in the fair value of the Karuna investment that were included in gain/(loss) on investments held at fair 
value within the Consolidated Statement of Comprehensive Income/(Loss). As of December 31, 2023, the Group held  886,885 
shares or 2.3 percent of total outstanding Karuna common stock. In December 2023, Karuna entered into a definitive merger 
agreement with Bristol Myers Squibb ("BMS") under which Karuna common shares were acquired by Bristol Myers Squibb for $330 
per share in March 2024. See Note 28. Subsequent Events. The fair value of the Group’s investment in Karuna is $280,708 as of 
December 31, 2023.  

Vor
Vor was deconsolidated in February 2019. As the Group did not hold common shares in Vor upon deconsolidation and the 
preferred shares it held did not have equity-like features. Therefore, the preferred shares held by the Group fell under the 
guidance of IFRS 9 and were treated as a financial asset held at fair value with changes in fair value recorded in the Consolidated 
Statement of Comprehensive Income/(Loss). 

2021
On January 8, 2021, the Group participated in the second closing of Vor’s Series B preferred share financing. For consideration of 
$500, the Group received an additional 961,538 Series B preferred shares. 

On February 9, 2021, Vor closed its initial public offering (the "IPO") of 9,828,017 shares of its common stock at a price of $18.00 
per share. Subsequent to the closing, the Group held 3,207,200 shares of Vor common stock, representing 8.6 percent of Vor 
common stock. 

2022
In August and December 2022, the Group sold an aggregate of 535,400 shares of Vor common stock for aggregate proceeds of 
$3,253.

During the years ended December 31, 2023,  2022 and 2021, the Group recognized a loss of $11,756, a loss of $16,247, and a 
gain of $3,903, respectively, for the changes in the fair value of the investment that were included in gain/(loss) on investments

Vor is $6,012 as of December 31, 2023.

Gelesis
Gelesis was deconsolidated in July 2019. The common stock held in Gelesis was accounted for under the equity method, while 
the preferred shares and warrants held by the Group fell under the guidance of IFRS 9 and were treated as financial assets held 
at fair value, with changes to the fair value of the instruments recorded through the Consolidated Statement of Comprehensive 
Income/(Loss). Please refer to Note 6. Investments in Associates for information regarding the Group's investment in Gelesis as an 
associate.

2021
During the year ended December 31, 2021, as the equity method based investment in Gelesis was reduced to zero previously, 
the Group allocated a portion of its share in the net loss in Gelesis of $73,703, to its preferred share and warrant investments in 
Gelesis, which were considered to be long-term interests in Gelesis.

2022
On January 13, 2022, Gelesis completed its business combination with Capstar Special Purpose Acquisition Corp ("Capstar"). 
As part of the business combination, all shares in Gelesis, common and preferred, including the shares held by the Group, were 
exchanged for common shares of the merged entity and unvested common shares that will vest upon the stock price of the new 
combined entity reaching certain target prices (hereinafter "Gelesis Earn-out Shares"). In addition, the Group invested $15,000 
in the class A common shares of Capstar as part of the Private Investment in Public Equity ("PIPE") transaction that took place 
immediately prior to the closing of the business combination and an additional approximately $4,961, as part of the Backstop 
agreement signed with Capstar on December 30, 2021 (See Note 6. Investments in Associates). Pursuant to the business 
combination, Gelesis became a wholly-owned subsidiary of Capstar and Capstar changed its name to Gelesis Holdings, Inc., 
which began trading on the New York Stock Exchange under the ticker symbol "GLS" on January 14, 2022. The exchange of the 
preferred stock (including warrants) for common stock (including common stock warrants) represents an additional investment in 
Gelesis equity investment. The Group recorded the changes in fair value of the preferred stock and warrants through the date 
of the exchange upon which the preferred shares and warrants were derecognized and recorded as an additional investment in 
Gelesis equity interest. All equity method losses allocated in prior periods against the investment in Gelesis held at fair value were 
reclassified to include within the equity method investment in Gelesis and were offset against the gain on dilution of interest. 

As part of the aforementioned exchange, the Group received 4,526,622 Gelesis Earn-out Shares, which were valued on the date 
of the exchange at $14,214. The Group accounted for such Gelesis Earn-out Shares under IFRS 9 as investments held at fair value 
with changes in fair value recorded through profit and loss.

2023
In February and May 2023, as part of Gelesis' issuance of senior secured promissory notes to the Group, Gelesis also issued to the 
Group (i) warrants to purchase 23,688,047 shares of Gelesis common stock with an exercise price of $0.2744 per share  (ii) warrants 
to purchase 192,307,692 shares of Gelesis common stock at an exercise price of $0.0182 per share and (iii) warrants to purchase 
43,133,803 shares of Gelesis common stock at an exercise price of $0.0142 per share. These warrants expire five years after 
issuance and are collectively referred to as the Gelesis 2023 Warrants.

The Gelesis 2023 Warrants were recorded at their initial fair value of $1,121 and then subsequently re-measured to fair value 
through the profit and loss. As of December 31, 2023, the fair value of the Gelesis 2023 Warrants was $0 as Gelesis ceased 
operations in October 2023.  

During the years ended December 31, 2023,  2022 and 2021, the Group recognized a loss of $1,264, a loss of  $18,476 and a gain 
of $34,566, respectively, related to the change in the fair value of these instruments that was included in gain/(loss) on investments 
held at fair value within the Consolidated Statement of Comprehensive Income/(Loss). 

Sonde
On May 25, 2022, Sonde completed a Series B preferred share financing, which resulted in the Group losing control over Sonde 
and the deconsolidation of Sonde. Therefore, the results of operations of Sonde are included in the Consolidated Financial 
Statements through the date of deconsolidation.

Upon deconsolidation, the Group derecognized its assets and liabilities and non-controlling interest in respect of Sonde and 
recorded its aforementioned investments in Sonde at fair value. The deconsolidation resulted in a gain of $27,251. As of the date 
of deconsolidation, the investment in Sonde preferred shares held at fair value amounted to $11,168. 

Following deconsolidation, the Group had significant influence in Sonde through its 48.2% voting interest in Sonde and its 
remaining representation on Sonde's Board of Directors. The Group holds Preferred A-1, A-2 and B shares. The Preferred A-1 
shares have the same terms as common stock and provide their shareholders with access to returns associated with a residual 
equity ownership in Sonde. Consequently, the investment in Preferred A-1 shares is accounted for under the equity method. The 
convertible Preferred A-2 and B shares do not provide their shareholders with access to returns associated with a residual equity 
interest and as such are accounted for under IFRS 9, as investments held at fair value with changes in fair value recorded in profit 
and loss. Under IFRS 9, the A-2 and B preferred share investments are categorized as debt instruments that are presented at fair 
value through profit and loss because the amounts receivable do not represent solely payments of principal and interest.

During the years ended December 31, 2023 and 2022, the Group recognized a loss of $994, and a gain of $235, respectively, for 
the changes in the fair value of the investment in Sonde that were included in gain/(loss) on investments held at fair value within 
the Consolidated Statement of Comprehensive Income/(Loss). The fair value of the Group’s investment in Sonde is $10,408 as of 
December 31, 2023.

Akili
Akili was deconsolidated in 2018. At time of deconsolidation, as the Group did not hold common shares in Akili and the preferred 
shares it held did not have equity-like features. Therefore, the preferred shares held by the Group fell under the guidance of IFRS 9 
and were treated as a financial asset held at fair value and changes to the fair value of the preferred shares were recorded through 
the Consolidated Statement of Comprehensive Income/(Loss), in accordance with IFRS 9. 

On May 25, 2021, Akili completed its Series D financing for gross proceeds of $110,000 in which Akili issued 13,053,508 Series D 
preferred shares. The Group did not participate in this round of financing and as a result, the Group's interest in Akili was reduced 
from 41.9 percent to 27.5 percent.

On August 19, 2022, Akili Interactive merged with Social Capital Suvretta Holdings Corp. I, a special purpose acquisition 
company.  The combined company's securities began trading on August 22, 2022 on the Nasdaq Stock Market under the ticker 
symbol "AKLI". As part of this transaction, the Akili Interactive shares held by the Group were exchanged for the common stock 
of the combined company's securities as well as unvested common stock ("Akili Earnout Shares") that will vest when the share 
price exceeds certain thresholds. In addition, as part of a PIPE transaction that took place concurrently with the closing of the 
transaction, the Group purchased 500,000 shares for a total consideration of $5,000. Following the closing of the aforementioned 
transactions, the Group holds 12,527,477 shares of the combined entity and 1,433,914 Akili Earn-out Shares, with fair value 
amounted to $6,422 as of December 31, 2023.

During the years ended December 31, 2023, 2022 and 2021, the Group recognized a loss of $8,681, a loss of $131,419, and 
a gain of $32,151, respectively, for the changes in the fair value of the investment in Akili that were included in gain/(loss) on 
investments held at fair value within the Consolidated Statement of Comprehensive Income/(Loss).

6.   Investments in Associates

Gelesis
Gelesis was founded by the Group and raised funding through preferred shares financings as well as issuances of warrants and 
loans. As of July 1, 2019, Gelesis was deconsolidated from the Group’s financial statements. Upon deconsolidation, the preferred 
shares and warrants held by the Group fell under the guidance of IFRS 9 Financial Instruments and were treated as financial assets 
held at fair value and the investment in common shares of Gelesis was subject to IAS 28 Investment in Associates as the Group had 
significant influence over Gelesis. 

2021
Due to the Group's share in the losses of Gelesis, in 2020, the Group's investment in Gelesis accounted for under the equity 
method was reduced to zero. Since the Group had investments in Gelesis warrants and preferred shares that were deemed to be 
long-term interests, the Group continued recognizing its share in Gelesis losses while applying such losses to its preferred share 
and warrant investment in Gelesis accounted for as an investment held at fair value. In 2021, total investment in Gelesis, including 
the long-term interests, was reduced to zero. Since the Group did not incur legal or constructive obligations or made payments 
on behalf of Gelesis, the Group discontinued recognizing equity method losses in 2021. As of December 31, 2021, unrecognized 
equity method losses amounted to $38,101, which included $709 of unrecognized other comprehensive loss.

During 2021, due to exercise of stock options into common shares in Gelesis, the Group's equity interest in Gelesis was reduced 
from 47.9 percent at December 31, 2020 to 42.0 percent as of December 31, 2021. The gain resulting from the issuance of shares 
to third parties and the resulting reduction in the Group's share in the accumulated deficit of Gelesis under the equity method was 
fully offset by the unrecognized equity method losses.

Backstop agreement – 2022 and 2021
On December 30, 2021, the Group signed a Backstop agreement with Capstar and had committed to acquire Capstar class A 
common shares at $10 per share immediately prior to the closing of the business combination between Gelesis and Capstar, in 
case, the Available Funds, as defined in the agreement, were less than $15,000. According to the Backstop agreement, if the 
Group had to acquire any shares under the agreement, the Group would receive an additional 1,322,500 class A common shares 
of Capstar at no additional consideration.

The Group determined that such agreement meets the definition of a derivative under IFRS 9 and as such should be recorded at 
fair value with changes in fair value recorded through profit and loss. The derivative was initially recorded at fair value adjusted 
to defer the day 1 gain equal to the difference between the fair value of $11,200 and transaction price of zero on the effective 
date of the Backstop agreement and as such was initially recorded at zero. The deferred gain was amortized over the period from 
the effective date until settlement date, January 13, 2022. During the years ended December 31, 2022 and 2021, the Group 
recognized income of $10,400 and $800, respectively, for the amortization of the deferred gain. During the year ended December 
31, 2022, the Group recognized a loss of $2,776 in respect of the decrease in the fair value of the derivative until the settlement 
date, resulting in a net gain of $7,624 recorded during the year ended December 31, 2022 in respect of the Backstop agreement. 
The gain was included in other Income/(expense) in the Consolidated Statement of Comprehensive Income/(Loss). The fair value 
of the derivative on the settlement date in the amount of $8,424 represents an additional investment in Gelesis as part of the SPAC 
transaction described below.

On January 13, 2022, as part of the conclusion of the aforementioned Backstop agreement, the Group acquired 496,145 class A 
common shares of Capstar for $4,961 and received an additional 1,322,500 class A common shares of Capstar for no additional 
consideration.

2022
Share exchange – Capstar
On January 13, 2022, Gelesis completed its business combination with Capstar. As part of the business combination, all shares 
in Gelesis, common and preferred, including the shares held by the Group, were exchanged for common shares of the merged 
entity and unvested common shares that will vest upon the stock price of the new combined entity reaching certain target prices 
(the "Gelesis Earn-out Shares"). In addition, the Group invested $15,000 in the class A common shares of Capstar as part of the 
PIPE transaction that took place immediately prior to the closing of the business combination and an additional $4,961, as part of 
the Backstop agreement described above. Pursuant to the business combination, Gelesis became a wholly-owned subsidiary of 
Capstar and Capstar changed its name to Gelesis Holdings, Inc., which began trading on the New York Stock Exchange under the 
ticker symbol "GLS" on January 14, 2022. Following the closing of the business combination, the PIPE transaction, the settlement 
of the aforementioned Backstop agreement with Capstar, and the exchange of all preferred shares in Gelesis to common shares in 
the new combined entity, the Group holds 16,727,582 common shares of Gelesis Holdings Inc., which was equal to approximately 
23.2% of Gelesis Holdings Inc's outstanding common shares at the time of the exchange. Due to the Group's significant equity 
holding and voting interest in Gelesis, the Group continued to maintain significant influence in Gelesis and as such continued to 
account for its Gelesis equity investment under the equity method.

Gelesis was deemed to be the acquirer in Gelesis Holdings Inc. and the financial assets and financial liabilities in Capstar were 
deemed to be acquired by Gelesis in consideration for the shares held by Capstar legacy shareholders. As such, the Group did 
not revalue the retained investment in Gelesis but rather treated the exchange as a dilution of its equity interest in Gelesis from 
42.0 percent as of December 31, 2021 to 22.8 percent as of January 13, 2022 (including warrants that provide its holders access 
to returns associated with equity holders). After considering the aforementioned additional investments, the exchange of the 
preferred stock, previously accounted for as an investment held at fair value, to common stock (and representing an additional 
equity investment in Gelesis), the earn-out shares received in Gelesis (see Note 5. Investments Held at Fair Value) and the offset of 
previously unrecognized equity method losses, the net gain recorded on the dilution of interest amounted to $28,255.

Impairment
Following Gelesis’ decline in its market price in 2022 and its lack of liquidity, the Group recorded an impairment loss of $8,390 
as of December 31, 2022 in respect of its investment in Gelesis. The recoverable amount of the investment in Gelesis was $4,910 
as of December 31, 2022, which was determined based on fair value less costs to sell (which were estimated to be insignificant). 
Fair value was determined based on level 1 of the fair value hierarchy as Gelesis shares were traded on an active market as of 
December 31, 2022.

The impairment loss was presented separately in the Consolidated Statement of Comprehensive Income/(loss) for the year ended 
December 31, 2022 in the line item impairment of investment in associates.

2023
During the year ended December 31, 2023, the Group entered into agreements with Gelesis to purchase senior secured 
convertible promissory notes and warrants for shares of Gelesis common stock  (see Note 7. Investment in Notes from Associates). 
The warrants to purchase shares of Gelesis common stock represented potential voting rights to the Group and it is therefore 
necessary to consider whether they were substantive. If these potential voting rights were substantive and the Group had the 
practical ability to exercise the rights and take control of greater than 50% of Gelesis common stock, the Group would be required 
to consolidate Gelesis under the accounting standards.

In February 2023, the Group obtained warrants to purchase 23,688,047 shares of Gelesis common stock (the “February Warrants”) 
at an exercise price of $0.2744 per share. The exercise of the February Warrants was subject to the approval of the Gelesis 
stockholders until May 1, 2023. On May 1, 2023, stockholder approval was no longer required for the Group to exercise the 
February Warrants. The potential voting rights associated with the February Warrants were not substantive as the exercise price of 
the February Warrants was at a significant premium to the fair value of the Gelesis common stock.

In May 2023, the Group obtained warrants to purchase 235,441,495 shares of Gelesis common stock (the “May Warrants”). The 
May Warrants were exercisable at the option of the Group and had an exercise price of either $0.0182 or $0.0142. The May 
Warrants were substantive as the Group would have benefited from exercising such warrants since their exercise price was at 
the money or at an insignificant premium over the fair value of the Gelesis common stock. However, that benefit from exercising 
the May Warrants only existed for a short period of time because in June 2023, the potential voting rights associated with the 
May Warrants were impacted by the terms and conditions of the Merger Agreement as described below and were no longer 
substantive.

Notes to the Consolidated Financial Statements continued

6.   Investments in Associates continued

In October 2023, the Group terminated the Merger Agreement with Gelesis and the potential voting rights associated with the 
May Warrants were not substantive. Also, in October 2023, Gelesis ceased operations and filed a voluntary petition for relief 
under the provisions of Chapter 7 of Title 11 of the United States Bankruptcy Code. A Chapter 7 trustee has been appointed by 
the Bankruptcy Court who has control over the assets and liabilities of Gelesis, effectively eliminating the authority and powers of 
the Board of Directors of Gelesis and its executive officers to act on behalf of Gelesis. The assets of Gelesis will be liquidated and 
Gelesis no longer has any officers or employees. The Group ceased accounting for Gelesis as an equity method investment as it no 
longer had significant influence in Gelesis. During the year ended December 31, 2023, the Group recorded $4,910 as its share in 
the losses of Gelesis and the Group’s balance in this equity method investment was zero as of December 31, 2023. 

Merger Agreement 
On June 12, 2023, PureTech Health LLC and Caviar Merger Sub LLC, a Delaware limited liability company and a wholly-owned 
subsidiary of PureTech (“Merger Sub”), entered into an agreement (the "Merger Agreement"), pursuant to which Gelesis would 
merge with and into Merger Sub, with Merger Sub continuing as the surviving company ( the “Merger”). If the Merger had been 
completed, PureTech would have acquired all issued and outstanding shares of common stock of Gelesis not otherwise held by 
PureTech, and Gelesis would have become an indirect wholly-owned subsidiary of PureTech.  On October 12, 2023, the Group 
terminated the Merger Agreement. 

Sonde
On May 25, 2022, Sonde completed a Series B preferred share financing. As a result of the aforementioned financing, the Group's 
voting interest was reduced below 50% and the Group lost its control over Sonde and as such ceased to consolidate Sonde on the 
date the round of financing was completed.  

Following deconsolidation, the Group has significant influence in Sonde through its voting interest in Sonde and its remaining 
representation on Sonde's Board of Directors. The Group's voting interest at date of deconsolidation and as of December 31, 2022 
was 48.2% and 40.17%, respectively. The Group holds Preferred A-1, A-2 and B shares. The Preferred A-1 shares, in substance, 
have the same terms as common stock and as such provide their shareholders with access to returns associated with a residual 
equity ownership in Sonde. Consequently, the investment in Preferred A-1 shares is accounted for under the equity method. The 
Preferred A-2 and B shares, however, do not provide their shareholders with access to returns associated with a residual equity 
interest and as such are accounted for under IFRS 9, as investments held at fair value.

The fair value of the Preferred A-1 shares on the date of deconsolidation amounted to $7,716, which is the initial value of the 
equity method investment in Sonde. 

During the years ended December 31, 2023 and 2022, the Group recorded losses of  $1,052  and  $3,443, respectively, related to 
Sonde's equity method of accounting.  As of December 31, 2023, the Sonde equity method investment has a balance of $3,185.

Gelesis
Unsecured Promissory Note
On July 27, 2022, the Group, as a lender, entered into an unsecured promissory note (the "Junior Note") with Gelesis, as a 
borrower, in the amount of $15,000. The Junior Note bears an annual interest rate of 15% per annum. The maturity date of the 
Junior Note is the earlier of December 31, 2023 or five business days following the consummation of a qualified financing by 
Gelesis. Based on the terms of the Junior Note, due to the option to convert to a variable amount of shares at the time of default, 
the Junior Note is required to be measured at fair value with changes in fair value recorded through profit and loss. 

As of December 31, 2023 and December 31, 2022 the fair value of the Junior Note was $0 and $16,501, respectively. In the year 
ended December 31, 2023, the Group recorded a loss of $16,501 for the change in the fair value of the Junior Note which was 
included in gain/(loss) on investments in notes from associates within the Consolidated Statement of Comprehensive Income/
(Loss). The fair value of the Junior Note was determined to be $0 as of December 31, 2023 as Gelesis has ceased operations and 
filed for bankruptcy. In the year ended December 31, 2022, the Group recorded interest income of $963 and a gain of $539 for 
the change in the fair value of the Junior Note which was included in other income/(expense) in the Consolidated Statement of 
Comprehensive Income/(Loss).

Senior Secured Convertible Promissory Notes
During the year ended December 31, 2023, the Group entered into multiple agreements with Gelesis to purchase for $11,850  
senior secured convertible promissory notes (the "Senior Notes") and warrants for share of Gelesis common stock. The initial fair 
value of the Senior Notes was determined to be $10,729 while $1,121 was determined to be the initial fair value of the warrants. 
The Senior Notes represent debt instruments that are presented at fair value through profit and loss as the amounts receivable do 
not solely represent payments of principal and interest as the Senior Notes are convertible into Gelesis common stock.  

The Senior Notes are secured by a first-priority lien on substantially all assets of Gelesis and the guarantors (other than the equity 
interests in, and assets held by Gelesis s.r.l., a subsidiary of Gelesis, and certain other exceptions).

In October 2023, Gelesis ceased operations and filed a voluntary petition for relief under the provisions of Chapter 7 of Title 
11 of the United States Bankruptcy Code. Therefore, the Group determined that the fair value of the Senior Notes was $0 as of 
December 31, 2023 and the Group recorded a loss of $10,729  for the changes in the fair value of the Senior Notes. The loss was 
included in gain/(loss) on investments in notes from associates in the Consolidated Statement of Comprehensive Income/(Loss). 

Vedanta
On April 24, 2023, Vedanta closed the second tranche of its convertible debt for additional proceeds of $18,000, of which $5,000 
were invested by the Group. The convertible debt carries an interest rate of 9 percent per annum. The debt has various conversion 
triggers and the conversion price is established at the lower of 80% of the equity price of the last financing round, or a certain pre-
money valuation cap established in the agreement. If the convertible debt is not earlier converted or repaid, the entire outstanding 
amount of the convertible debt shall be due and payable upon the earliest to occur of (a) the later of (x) November 1, 2025 and 
(y) the date which is sixty (60) days after all amounts owed under, or in connection with, the loan Vedanta received from a certain 
investor have been paid in full, or (b) the consummation of a Deemed Liquidation Event (as defined in Vedanta’s Amended and 
Restated Certificate of Incorporation).

Due to the terms of the convertible debt, the investment in such convertible debt is measured at fair value with changes in the fair 
value recorded through profit and loss. During the years ended December 31, 2023, the Group recorded a loss of $400 for the 
changes in the fair value of the Vedanta convertible debt which was included in gain/(loss) on investments in notes from associates 
in the Consolidated Statement of Comprehensive Income/(Loss). 

Following is the activity in respect of investments in notes from associates during the periods. The fair value of the $4,600 note 
from associate as of December 31, 2023 is determined using unobservable Level 3 inputs. See Note 18. Financial Instruments for 
additional information.

9.  Share-based Payments

Share-based payments includes stock options, time-based restricted stock units (“RSUs”) and performance-based RSUs in which 
the expense is recognized based on the grant date fair value of these awards, except for performance-based RSUs to executives 
that are treated as liability awards where expense is recognized based on reporting date fair value up until settlement date.

Share-based Payment Expense
The Group's share-based payment expense for the years ended December 31, 2023, 2022 and 2021, was $4,415, $14,699, and 
$13,950 respectively. The following table provides the classification of the Group’s consolidated share-based payment expense as

The Performance Share Plan
In June 2015, the Group adopted the Performance Stock Plan (the “2015 PSP”). Under the 2015 PSP and subsequent 
amendments, awards of ordinary shares may be made to the Directors, senior managers and employees, and other individuals 
providing services to the Group up to a maximum authorized amount of 10.0 percent of the total ordinary shares outstanding. 
The shares have various vesting terms over a period of service between one and four years, provided the recipient remains 
continuously engaged as a service provider. The options awards expire 10 years from the grant date.

In June 2023 the Group adopted a new Performance Stock Plan (the "2023 PSP") that has the same terms as the 2015 PSP but 
instituted for all new awards a limit of 10.0 percent of the total ordinary shares outstanding over a five-year period.

The share-based awards granted under the PSPs are generally equity-settled (see cash settlements below). As of December 31, 
2023, the Group had issued 27,384,777 units of share-based awards under these plans.

Each RSU entitles the holder to one ordinary share on vesting and the RSU awards are generally based on a vesting schedule over 
a one to three-year requisite service period in which the Group recognizes compensation expense for the RSUs. Following vesting, 
each recipient will be required to make a payment of one pence per ordinary share on settlement of the RSUs. 

RSUs granted to the non-executive directors are time-based and equity-settled. The grant date fair value on such RSUs is 
recognized over the vesting term.

RSUs granted to executives are performance-based and vesting of such RSUs is subject to the satisfaction of both performance 
and market conditions. The performance condition is based on the achievement of the Group's strategic targets. The market 
conditions are based on the achievement of the absolute total shareholder return (“TSR”), TSR as compared to the FTSE 250 
Index, and TSR as compared to the MSCI Europe Health Care Index. The RSU award performance criteria have changed over time 
as the criteria are continually evaluated by the Group’s Remuneration Committee.

The Group recognizes the estimated fair value of performance-based awards with non-market conditions as share-based 
compensation expense over the performance period based upon its determination of whether it is probable that the performance 
targets will be achieved. The Group assesses the probability of achieving the performance targets at each reporting period. 
Cumulative adjustments, if any, are recorded to reflect subsequent changes in the estimated outcome of performance-related 
conditions.

9.  Share-based Payments continued

The fair value of the performance-based awards with market conditions is based on the Monte Carlo simulation analysis utilizing 
a Geometric Brownian Motion process with 100,000 simulations to value those shares. The model considers share price volatility, 
risk-free rate and other covariance of comparable public companies and other market data to predict distribution of relative share 
performance.

Liability settled RSUs classification
The RSUs to executives are treated as liability awards as the Group has a historical practice of settling these awards in cash, and as 
such adjusted to fair value at every reporting date until settlement with changes in fair value recorded in earnings as stock based 
compensation expense.

The Group incurred share-based payment expenses for RSUs of $827 (including $402 expense in respect of RSU liability awards), 
$1,637 (including $1,131 expense in respect of RSU liability awards), and $1,540 (including $589 expense in respect of RSU liability 
awards) for the years ended December 31, 2023, 2022 and 2021, respectively. The decrease in the share-based compensation 
expense in respect of the RSUs for the year ended December 31, 2023, as compared to the year ended December 31, 2022 is due 
to reduction in the fair value of the liability awards.

As of December 31, 2023, the carrying amount of the RSU liability awards was $4,782, $1,281 current; $3,501 non current, out of 
which $1,283 related to awards that have met all their performance and market conditions.

11.  Earnings/(Loss) per Share 

Basic earnings/(loss) per share is calculated by dividing the Group's net income or loss for the year attributable to ordinary 
shareholders by the weighted average number of ordinary shares outstanding, net of treasury shares.

Diluted EPS is calculated by dividing the Group's net income or loss for the year by the weighted average number of ordinary 
shares outstanding, net of treasury shares, plus the weighted average number of ordinary shares that would be issued at 
conversion of all the dilutive potential ordinary shares into ordinary shares. Dilutive effects arise from equity-settled shares from the 
Group's share-based plans. 

For the years ended December 31, 2023, 2022 and 2021, the Group incurred a net loss and therefore all outstanding potential 
securities were considered anti-dilutive. The amount of potential securities that were excluded from the diluted calculation 
amounted to 1,509,900, 3,134,131 and 6,553,905 shares, respectively.

Substantially all the intangible asset licenses represent in-process-research-and-development assets since they are still being 
developed and not ready for their intended use. As such, these assets are not amortized but tested for impairment annually. 

During the year ended December 31, 2023, the Group wrote off two of its research intangible assets for which research was ceased 
in the amount of $105.

During the year ended December 31, 2023, Vedanta, Inc. was deconsolidated and as such, $19 net in intangible assets were 
derecognized.

During  the year ended December 31,2022, the Group wrote off one of its research intangible assets for which research was 
ceased in the amount of $163.

During the year ended December 31, 2022, Sonde Health, Inc. was deconsolidated and as such, $18 net intangible assets were 
derecognized.

The Group tested all intangible assets for impairment as of the balance sheet date and concluded that none of such assets were 
impaired. 

The Group had negligible amortization expense for the years ended December 31, 2022 and 2021 and no amortization expense 
for the year ended December 31, 2023.

Changes in share capital and share premium relate primarily to incentive options exercises during the period.

Shareholders are entitled to vote on all matters submitted to shareholders for a vote. Each ordinary share is entitled to one vote 
and is entitled to receive dividends when and if declared by the Group’s Directors. 

On June 18, 2015, the Group acquired the entire issued share capital of PureTech LLC in return for 159,648,387 ordinary shares. 
This was accounted for as a common control transaction at cost. It was deemed that the share capital was issued in line with 
movements in share capital as shown prior to the transaction taking place. In addition, the merger reserve records amounts 
previously recorded as share premium.

Other reserves comprise the cumulative credit to share-based payment reserves corresponding to share-based payment expenses 
recognized through Consolidated Statement of Comprehensive Income/(Loss), settlements of vested stock awards as well as other 
additions that flow directly through equity such as the excess or deficit from changes in ownership of subsidiaries while control is 
maintained by the Group.

On May 9, 2022, the Group announced the commencement of a $50,000 share repurchase program (the "Program") of its ordinary 
shares of one pence each (the “Ordinary Shares”). The Group executed the Program in two equal tranches. The Group entered 
into an irrevocable non-discretionary instruction with Jefferies International Limited (“Jefferies”) in relation to the purchase by 
Jefferies of the Ordinary Shares for an aggregate consideration (excluding expenses) of no greater than $25,000 for each tranche, 
and the simultaneous on-sale of such Ordinary Shares by Jefferies to the Group, subject to certain volume and price restrictions. 
Jefferies made its trading decisions in relation to the Ordinary Shares independently of, and uninfluenced by, the Group. Purchases 
could continue during any close period to which the Group was subject. The instruction to Jeffries could be amended or withdrawn 
so long as the Group was not in a close period or otherwise in possession of inside information.

Any purchases of the Ordinary Shares under the Program were carried out on the London Stock Exchange and could be carried 
out on any other UK recognized investment exchange in accordance with pre-set parameters and subject to limits prescribed by 
the Group’s general authority to repurchase the Ordinary Shares granted by its shareholders at its annual general meeting on 
May 27, 2021, and relevant Rules and Regulations. All Ordinary Shares repurchased under the Program are held in treasury and 
re-issued for settlement of share-based awards. As of December 31, 2023, the Group had repurchased an aggregate of 18,278,873 
Ordinary Shares under the share repurchase program with 7,683,526 shares repurchased in 2023. The Program was completed 
during the month ended February 2024.

As of December 31, 2023, the Group’s issued share capital was 289,468,159 shares, including 17,614,428 shares repurchased 
under the Program and were held by the Group in treasury. The Group does not have a limited amount of authorized share capital.

16.  Subsidiary Preferred Shares 

Preferred shares issued by subsidiaries often contain redemption and conversion features that are assessed under IFRS 9 in 
conjunction with the host preferred share instrument. This balance represents subsidiary preferred shares issued to third parties. 

The subsidiary preferred shares are redeemable upon the occurrence of a contingent event, other than full liquidation of the 
Group, that is not considered to be within the control of the Group. Therefore these subsidiary preferred shares are classified as 
liabilities. These liabilities are measured at fair value through profit and loss. The preferred shares are convertible into ordinary 
shares of the subsidiaries at the option of the holders and are mandatorily convertible into ordinary shares under certain 
circumstances. Under certain scenarios, the number of ordinary shares receivable on conversion will change and therefore, the 
number of shares that will be issued is not fixed. As such the conversion feature is considered to be an embedded derivative that 
normally would require bifurcation. However, since the preferred share liabilities are measured at fair value through profit and loss, 
as mentioned above, no bifurcation is required. 

The preferred shares are entitled to vote with holders of common shares on an as converted basis.

The fair value of all subsidiary preferred shares as of December 31, 2023 and December 31, 2022, is as follows: 

As of December 31,

As is customary, in the event of any voluntary or involuntary liquidation, dissolution or winding up of a subsidiary, the holders 
of subsidiary preferred shares which are outstanding shall be entitled to be paid out of the assets of the subsidiary available for 
distribution to shareholders and before any payment shall be made to holders of ordinary shares. A merger, acquisition, sale of 
voting control or other transaction of a subsidiary in which the shareholders of the subsidiary immediately before the transaction 
do not own a majority of the outstanding shares of the surviving company shall be deemed to be a liquidation event. Additionally, 
a sale, lease, transfer or other disposition of all or substantially all of the assets of the subsidiary shall also be deemed a liquidation 
event.

As of December 31, 2023 and December 31, 2022, the minimum liquidation preference reflecting the amounts that would be 
payable to the subsidiary preferred holders upon a liquidation event of the subsidiaries, is as follows:

17.  Sale of Future Royalties Liability

On March 4, 2011, the Group entered into a license agreement with Karuna Therapeutics, Inc. (“Karuna”) according to which 
the Group granted Karuna an exclusive license to research, develop and sell KarXT in exchange for a royalty on annual net sales, 
development and regulatory milestones and a fixed portion of sublicensing income, if any (hereinafter “License Agreement”).

On March 22, 2023, the Group signed an agreement with Royalty Pharma  (hereinafter "Royalty Purchase Agreement"), according 
to which the Group sold Royalty Pharma a partial right to receive royalty payments made by Karuna in respect of net sales of 
KarXT, if and when received. According to the Royalty Purchase Agreement, all royalties due to the Group under the License 
Agreement will be paid to Royalty Pharma up until an annual threshold of $60,000, while all royalties above such annual threshold 
in a given year will be split 33% to Royalty Pharma and 67% to the Group. Under the terms of the Royalty Purchase Agreement, 
the Group received a non-refundable initial payment of $100,000 at the execution of the Royalty Purchase Agreement and is 
eligible to receive additional payments in the aggregate of up to an additional $400,000 based on the achievement of certain 
regulatory and commercial milestones.

The Group continues to hold the rights under the License Agreement and has a contractual obligation to deliver cash to Royalty 
Pharma for a portion of the royalties it receives. Therefore, the Group will continue to account for any royalties and regulatory 
milestones due to the Group under the License Agreement as revenue in its Consolidated Statement of Comprehensive Income/
(Loss) and record the proceeds from the Royalty Purchase Agreement as a financial liability on its Consolidated Statement of 
Financial Position. In determining the appropriate accounting treatment for the Royalty Purchase Agreement, management applied 
significant judgement.

The acquisition of Karuna by Bristol Meyers Squibb (NYSE: BMY), which closed on March 18, 2024, had no impact on the Group's 
rights or obligations under the License Agreement or Royalty Purchase Agreement, each of which remains in full force and effect.

In order to determine the amortized cost of the sale of future royalties liability, management is required to estimate the total 
amount of future receipts from and payments to Royalty Pharma under the Royalty Purchase Agreement over the life of the 
agreement. The $100,000 liability, recorded at execution of the Royalty Purchase Agreement, will be accreted to the total of these 
receipts and payments as interest expense over the life of the Royalty Purchase Agreement. These estimates contain assumptions 
that impact both the amortized cost of the liability and the interest expense that will be recognized in future periods. 

Additional proceeds received from Royalty Pharma will increase the Group’s financial liability. As royalty payments are made 
to Royalty Pharma, the balance of the liability will be effectively repaid over the life of the Royalty Purchase Agreement. The 
estimated timing and amount of royalty payments to and proceeds from Royalty Pharma are likely to change over the life of the 
Royalty Purchase Agreement. A significant increase or decrease in estimated royalty payments, or a significant shift in the timing 
of cash flows, will materially impact the sale of future royalties liability, interest expense and the time period for repayment. The 
Group will periodically assess the expected payments to, or proceeds from, Royalty Pharma, and any such changes in amount or 
timing of cash flows will require the Group to re-calculate the amortized cost of the sale of future royalties liability as the present 
value of the estimated future cash flows from the Royalty Purchase Agreement that are discounted at the liability’s original effective 
interest rate. The adjustment is recognized immediately in profit or loss as income or expense. 

The following shows the activity in respect of the sale of future royalties liability:

18.  Financial Instruments 

The Group’s financial instruments consist of financial assets in the form of notes, convertible notes and investment in shares, and 
financial liabilities, including preferred shares. Many of these financial instruments are presented at fair value, with changes in fair 
value recorded through profit and loss.

Fair Value Process
For financial instruments measured at fair value under IFRS 9, the change in the fair value is reflected through profit and loss. Using 
the guidance in IFRS 13, the total business enterprise value and allocable equity of each entity being valued can be determined 
using a market backsolve approach through a recent arm’s length financing round (or a future probable arm's length transaction), 
market/asset probability-weighted expected return method ("PWERM") approach, discounted cash flow approach, or hybrid 
approaches. The approaches, in order of strongest fair value evidence, are detailed as follows:

Valuation Method

Description

Market – Backsolve

Market/Asset – PWERM

Income Based – DCF

The market backsolve approach benchmarks the original issue price (OIP) of the company’s latest 
funding transaction as current value.
Under a PWERM, the company value is based upon the probability-weighted present value of 
expected future investment returns, considering each of the possible future outcomes available to the 
enterprise. Possible future outcomes can include IPO scenarios, potential SPAC transactions, merger 
and acquisition transactions as well as other similar exit transactions of the investee.
The income approach is used to estimate fair value based on the income streams, such as cash flows 
or earnings, that an asset or business can be expected to generate.

At each measurement date, investments held at fair value (that are not publicly traded) as well as the fair value of preferred share 
liabilities, including embedded conversion rights that are not bifurcated, were determined using the following allocation methods: 
option pricing model (“OPM”), PWERM, or hybrid allocation framework. The methods are detailed as follows:

Allocation Method

Description

OPM

PWERM

Hybrid

The OPM model treats preferred stock as call options on the enterprise’s equity value, with exercise 
prices based on the liquidation preferences of the preferred stock. 
Under a PWERM, share value is based upon the probability-weighted present value of expected 
future investment returns, considering each of the possible future outcomes available to the 
enterprise, as well as the rights of each share class. 
The hybrid method is a combination of the PWERM and OPM. Under the hybrid method, multiple 
liquidity scenarios are weighted based on the probability of the scenario's occurrence, similar to 
the PWERM, while also utilizing the OPM to estimate the allocation of value in one or more of the 
scenarios. 

Valuation policies and procedures are regularly monitored by the Group. Fair value measurements, including those categorized 
within Level 3, are prepared and reviewed for reasonableness and compliance with the fair value measurements guidance under 
IFRS accounting standards. The Group measures fair value using the following fair value hierarchy that reflects the significance of 
the inputs used in making the measurements:

Fair Value
Hierarchy Level

Description

Level 1
Level 2

Level 3

Inputs that are quoted market prices (unadjusted) in active markets for identical instruments.
Inputs other than quoted prices included within Level 1 that are observable either directly (i.e. as 
prices) or indirectly (i.e. derived from prices). 
Inputs that are unobservable. This category includes all instruments for which the valuation technique 
includes inputs not based on observable data and the unobservable inputs have a significant effect 
on the instruments' valuation. 

Whilst the Group considers the methodologies and assumptions adopted in fair value measurements as supportable and 
reasonable, because of the inherent uncertainty of valuation, those estimated values may differ significantly from the values that 
would have been used had a ready market for the investment existed.

The change in fair value of preferred shares and convertible notes liabilities are recorded in finance income/(costs) – fair value 
accounting in the Consolidated Statement of Comprehensive Income/(Loss).

Investments Held at Fair Value
Karuna, Vor and Akili Valuation
Karuna (Nasdaq: KRTX), Vor (Nasdaq: VOR), Akili (Nasdaq: AKLI) and additional immaterial investments are listed entities on an 
active exchange, and as such, the fair value as of December 31, 2023, was calculated utilizing the quoted common share price 
which is categorized as Level 1 in the fair value hierarchy. 

Vedanta and Sonde
As of December 31, 2023, the Group accounts for the following investments under IFRS 9 as investments held at fair value with 
changes in fair value through the profit and loss: Sonde preferred A-2 and B shares and Vedanta convertible preferred shares 
(subsequent to the date of deconsolidation). The valuation of the aforementioned investments is categorized as Level 3 in the fair 
value hierarchy due to the use of significant unobservable inputs to value such assets. During the year ended December 31, 2023, 
the Group recorded such investments at fair value and recognized a loss of $7,298 for the change in fair value of the investments. 
In addition, the Group determined that the fair value of its investment in the Gelesis 2023 Warrants was $0 as Gelesis ceased 
operations in October 2023.

The following table summarizes the changes in all the Group’s investments held at fair value, which were categorized as Level 3 in

Investments in Notes from Associates
As of December 31, 2022, the investment in notes from associates was $16,501 and represents investments the Group made in 
convertible promissory notes of Gelesis. During the year ended December 31, 2023, the Group invested $10,729 in convertible 
promissory notes of Gelesis and $5,000 in a convertible note of Vedanta. The Group recorded a loss of $27,630 for the change in 
fair value of the notes from associates in the gain/(loss) on investments in notes from associates within the Consolidated Statement 
of Comprehensive Income/Loss. The loss was driven by a reduction in the fair value of the Gelesis convertible promissory notes of 
$27,230 as Gelesis filed for bankruptcy in October 2023 and a change in the fair value of the Vedanata convertible note of $400.  

The convertible debt issued by Vedanta was valued using a market backsolve approach that leverages a Monte Carlo simulation. 
The significant unobservable inputs categorized as Level 3 in the fair value hierarchy used at December 31, 2023, in the fair value 
measurement of the convertible debt are the same as the inputs disclosed above for Vedanta preferred shares.

19.  Subsidiary Notes Payable 

The subsidiary notes payable are comprised of loans and convertible notes. As of December 31, 2023 and December 31, 2022, 
the loan in Follica and the convertible notes for Knode and Appeering did not contain embedded derivatives and therefore these 
instruments continue to be held at amortized cost. The notes payable consist of the following:

On April 6, 2021, and on November 24, 2021, Sonde issued unsecured convertible promissory notes to its existing shareholders 
for a combined total of $4,329, of which $2,215 were issued to third-party shareholders (and $2,113 were issued to the Group 
and eliminated in consolidation). In addition, in March 2022, Sonde issued an additional amount of $921, of which $393 were 
issued to third parties (and $528 issued to the Group and eliminated in consolidation). The notes bore interest at an annual rate of 
6.0 percent and were to mature on the second anniversary of the issuance. The notes were to mandatorily convert in a Qualified 
Financing, as defined in the note purchase agreement, at a discount of 20.0 percent from the price per share in the Qualified 
Financing. In addition, the notes allowed for optional conversion concurrently with a discount of 20.0 percent from the price per 
share in the Non Qualified Equity Financing. Upon the completion of the Preferred B round of financing in Sonde on May 25, 
2022, the Group lost control in Sonde and all convertible notes were derecognized as part of the deconsolidation – See Note 5. 
Investments Held at Fair Value.

For Sonde convertible notes, since these notes contained embedded derivatives, the notes were assessed under IFRS 9 and the 
entire financial instruments were elected to be accounted for as FVTPL. The Sonde notes were deconsolidated in May 2022 as 
described above.

20.  Non-Controlling Interest

As of December 31, 2023,  non-controlling interests include Entrega and Follica. Ownership interests of the non-controlling 
interests in these entities as of December 31, 2023 were 11.7 percent, and 19.9 percent, respectively. As of December 31, 2022, 
non-controlling interests include Entrega, Follica, and Vedanta. Ownership interests of the non-controlling interests in these entities 
were 11.7 percent , 19.9 percent, and 12.2 percent, respectively. As of December 31, 2021, non-controlling interests include 
Entrega, Follica, Sonde, and Vedanta. Ownership interests of the non-controlling interests in these entities were 11.7 percent, 
19.9 percent, 6.2 percent and 3.7 percent, respectively. During the year ended December 31, 2023, Vedanta Biosciences, Inc was 
deconsolidated. During the year ended December 31, 2022, Sonde Health, Inc was deconsolidated. See Note 5. Investments Held 
at Fair Value. 

Non-controlling interests include the amounts recorded for subsidiary stock options.

On June 11, 2021, the Group acquired the remaining 17.1 percent of the minority non-controlling interests of Alivio (after exercise 
of all in the money stock options) increasing its ownership to 100.0 percent of Alivio. The consideration for such non-controlling 
interests amounted to $1,224, to be paid in three equal installments, with the first installment of $408 paid at the effective date of 
the transaction and two additional installments to be paid upon the occurrence of certain contingent events. The Group recorded 
a contingent consideration liability of $560 at fair value for the two additional installments, resulting in a total acquisition cost 
of $968. The excess of the consideration paid over the book value of the non-controlling interest of approximately $9,636 was 
recorded directly as a charge to shareholders’ equity. The second installment of $408 was paid in July 2021, upon the occurrence 
of the contingent event specified in the agreement. The contingent consideration liability was adjusted to fair value at the end 
of each reporting period with changes in fair value recorded in earnings. Changes in fair value of the aforementioned contingent 
consideration liability were not material. As of December 31, 2022, the remaining contingent liability was reduced to zero as the 
second contingent event did not occur.

On December 1, 2021, option holders in Entrega exercised options into shares of common stock, increasing the NCI interest held 
from 0.2 percent to 11.7 percent. During 2021, option holders in Vedanta exercised options and increased the NCI interest to 
3.7 percent. The exercise of the options resulted in an increase in the NCI share in Entrega and Vedanta shareholder's deficit of 
$5,887. The amount together with the consideration paid by NCI ($101) amounted to $5,988 and was recorded as a gain directly 
in shareholders' equity.

On February 15, 2022, option holders in Vedanta exercised options into shares of common stock, increasing the NCI interest held 
from 3.7 percent to 12.2 percent. The exercise of the options resulted in an increase in the NCI share in Vedanta shareholder's 
deficit of $15,171. The amount together with the consideration paid by NCI ($7) amounted to $15,171 and was recorded as a gain 
directly in shareholders' equity.

22.  Long-term loan

In September 2020, Vedanta entered into a $15,000 loan and security agreement with Oxford Finance LLC. The loan is secured 
by Vedanta's assets, including equipment, inventory and intellectual property. The loan bears a floating interest rate of 7.7 
percent plus the greater of (i) 30 day U.S. Dollar LIBOR reported in the Wall Street Journal or (ii) 0.17 percent. The loan matures 
September 2025 and requires interest-only payments prior to 2023. The loan also carries a final fee upon full repayment of 7.0 
percent of the original principal, or $1,050. As part of the loan agreement, Vedanta also issued Oxford Finance LLC 12,886 Series 
C-2 preferred share warrants with an exercise price of $23.28 per share, expiring September 2030. The outstanding loan balance 
totaled approximately $15,400 as of December 31, 2022. On March 1, 2023, the Group derecognized the loan in connection with 
Vedanta's deconsolidation. Refer to Note 5. Investments Held at Fair Value.

During the year ended December 31, 2019, the Group entered into a lease agreement for certain premises consisting of 50,858 
rentable square feet of space located at 6 Tide Street, Boston, Massachusetts. The lease commenced on April 26, 2019 for an 
initial term consisting of ten years and three months, and there is an option to extend the lease for two consecutive periods of 
five years each. The Group assessed at the lease commencement date whether it was reasonably certain to exercise the extension 
options, and deemed such options were not reasonably certain to be exercised. The Group will reassess whether it is reasonably 
certain to exercise the options only if there is a significant event or significant change in circumstances within its control. 

On June 26, 2019, the Group executed a sublease agreement with Gelesis. The lease is for 9,446 rentable square feet located 
on the sixth floor of the Group’s former office at 501 Boylston Street, Boston, Massachusetts. The sublease was set to expire on 
August 31, 2025, and was determined to be a finance lease. Gelesis ceased operations and filed for bankruptcy on October 30, 
2023. As a result, the Group wrote off its receivable in the lease of $1,266 in 2023. 

On January 23, 2023, the Group executed a sublease agreement with Allonnia, LLC (“Allonnia”). The sublease is for approximately 
11,000 rentable square feet located on the third floor of the 6 Tide Street building where the Group’s offices are currently located. 
Allonnia obtained possession of the premises on February 17, 2023 with a rent commencement date of May 17, 2023. The lease 
term is two years from the rent commencement date, and Allonnia has the option to extend the sublease for an additional year at 
the same terms. The annual lease fee is $1,111 per year. The sublease was determined to be an operating lease, and as such, the 
total lease payments under the sublease agreement are recognized over the lease term on a straight-line basis. In February 2024, 
Allonnia exercised the option and extended the lease term through May 31, 2026.

Rental income recognized by the Group during the year ended December 31, 2023 was $781 which was included in the other 
income/(expense) line item in the Consolidated Statement of Comprehensive Income/(Loss). In the year ended December 31, 
2022, the Group did not recognize any rental income.

24.  Capital and Financial Risk Management 

Capital Risk Management
The Group's capital and financial risk management policy is to maintain a strong capital base to support its strategic priorities, 
maintain investor, creditor and market confidence as well as sustain the future development of the business. The Group’s 
objectives when managing capital are to safeguard its ability to continue as a going concern, to provide returns for shareholders 
and benefits for other stakeholders, and to maintain an optimal capital structure to reduce the cost of capital. To maintain or adjust 
the capital structure, the Group may issue new shares or incur new debt. The Group has no material externally imposed capital 
requirements. The Group’s share capital is set out in Note 15. Equity.

Management continuously monitors the level of capital deployed and available for deployment in the Wholly-Owned Programs  
segment and at Founded Entities. The Directors seek to maintain a balance between the higher returns that might be possible with 
higher levels of deployed capital and the advantages and security afforded by a sound capital position.

The Group’s Directors have overall responsibility for the establishment and oversight of the Group's capital and risk management 
framework. The Group is exposed to certain risks through its normal course of operations. The Group’s main objective in using 
financial instruments is to promote the development and commercialization of intellectual property through the raising and 
investing of funds for this purpose. The nature, amount and timing of investments are determined by planned future investment 
activity. Due to the nature of activities and with the aim to maintain the investors’ funds as secure and protected, the Group’s 
policy is to hold any excess funds in highly liquid and readily available financial instruments and maintain minimal exposure to 
other financial risks.

The Group has exposure to the following risks arising from financial instruments:

Credit Risk
Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its 
contractual obligations. Financial instruments that potentially subject the Group to concentrations of credit risk consist principally 
of cash and cash equivalents, short-term investments, and trade and other receivables. The Group held the following balances (not 
including the income tax receivable resulting from overpayment of income taxes as of December 31, 2022. See Note 27. Taxation):

The Group invests its excess cash in U.S. Treasury Bills (presented as short-term investments), and money market accounts, which 
the Group believes are of high credit quality. Further, the Group's cash and cash equivalents and short-term investments are held 
at diverse, investment-grade financial institutions.

The Group assesses the credit quality of customers on an ongoing basis. The credit quality of financial assets is assessed by 
historical and recent payment history, counterparty financial position, and reference to credit ratings (if available) or to historical 
information about counterparty default rates. The Group does not have expected credit losses due to the high credit quality or 
healthy financial conditions of these counterparties. As of December 31, 2023 and 2022, none of the trade and other receivables 
were impaired.

Liquidity Risk
Liquidity risk is the risk that the Group will encounter difficulty in meeting the obligations associated with its financial liabilities that 
are settled by delivering cash or another financial asset. The Group actively manages its liquidity risk by closely monitoring the 
maturity of its financial assets and liabilities and projected cash flows from operations, under both normal and stressed conditions, 
without incurring unacceptable losses or risking damage to the Group’s reputation. Due to the nature of these financial liabilities, 
the funds are available on demand to provide optimal financial flexibility.

The table below summarizes the maturity profile of the Group’s financial liabilities, including subsidiary preferred shares that have 
customary liquidation preferences, as of December 31, 2023 and 2022, based on contractual undiscounted payments:

Interest Rate Sensitivity 
As of December 31, 2023, the Group had cash and cash equivalents of $191,081, and short-term investments of $136,062. The 
Group's exposure to interest rate sensitivity is impacted by changes in the underlying U.K. and U.S. bank interest rates. The Group 
has not entered into investments for trading or speculative purposes. Due to the conservative nature of the Group's investment 
portfolio, which is predicated on capital preservation and investments in short duration, high-quality U.S. Treasury Bills and 
related money market accounts, a change in interest rates would not have a material effect on the fair market value of the Group's 
portfolio, and therefore, the Group does not expect operating results or cash flows to be significantly affected by changes in 
market interest rates.

Controlled Founded Entity Investments
The Group maintains investments in certain Controlled Founded Entities. The Group’s investments in Controlled Founded Entities 
are eliminated as intercompany transactions upon financial consolidation. The Group is, however, exposed to a preferred share 
liability owing to the terms of existing preferred shares and the ownership of Controlled Founded Entities preferred shares by 
third parties. As discussed in Note 16. Subsidiary Preferred Shares, certain of the Group’s subsidiaries have issued preferred shares 
that include the right to receive a payment in the event of any voluntary or involuntary liquidation, dissolution or winding up of a 
subsidiary, including in the event of "deemed liquidation" as defined in the incorporation documents of the entities, which shall be 
paid out of the assets of the subsidiary available for distribution to shareholders, and before any payment shall be made to holders 
of ordinary shares. The liability of preferred shares is maintained at fair value through the profit and loss. The Group’s cash position 
supports the business activities of the Controlled Founded Entities. Accordingly, the Group views exposure to the third party 
preferred share liability as low.

Deconsolidated Founded Entity Investments
The Group maintains certain debt or equity holdings in Founded Entities that are deconsolidated. These holdings are deemed 
either as investments and accounted for as investments held at fair value, or as associates and accounted for under the equity 
method. The Group's exposure to investments held at fair value is $317,841 as of December 31, 2023, and the Group may or may 
not be able to realize the value in the future. Accordingly, the Group views the risk as high. The Group’s exposure to investments 
in associates is limited to the carrying amount of the investment in an associate. The Group is not exposed to further contractual 
obligations or contingent liabilities beyond the value of the initial investments. Accordingly, the Group does not view this as a high 
risk. As of December 31, 2023, Sonde is the only associate, and the carrying amount of the investment as associate is $3,185.

Equity Price Risk
As of December 31, 2023, the Group held 886,885 common shares of Karuna, 2,671,800 common shares of Vor and 12,527,477 
common shares of Akili. The fair value of these investments in Karuna, Vor and Akili was $292,831, of which approximately 96% is 
related to the Karuna common shares. 

The investments in Karuna, Vor and Akili are exposed to fluctuations in the market price of these common shares. The effect of 
a 10.0 percent adverse change in the market price of Karuna, Vor and Akili common shares would cause a loss of approximately 
$29,283 to be recognized as a component of other income (expense) in the Consolidated Statement of Comprehensive Income/
(Loss). However, the Group views exposure to equity price risk as low due to the definitive merger agreement Karuna entered into 
with Bristol Myers Squibb "BMS") in December 2023 under which Karuna common shares were acquired by Bristol Myers Squibb 
for $330 per share in March 2024. 

Foreign Exchange Risk
The Group maintains consolidated financial statements in the Group's functional currency, which is the U.S. dollar. Monetary assets 
and liabilities denominated in currencies other than the functional currency are translated into the functional currency at exchange 
rates prevailing at the balance sheet dates. Non-monetary assets and liabilities denominated in foreign currencies are translated 
into the functional currency at the exchange rates prevailing at the date of the transaction. Exchange gains or losses arising 
from foreign currency transactions are included in the determination of net income (loss) for the respective periods. Such foreign 
currency gains or losses were not material for all reported periods. 

The Group does not currently engage in currency hedging activities since its foreign currency risk is limited, but the Group may 
begin to do so in the future if and when its foreign currency risk exposure changes.

25.  Commitments and Contingencies 

The Group is a party to certain licensing agreements where the Group is licensing IP from third parties. In consideration for 
such licenses, the Group has made upfront payments and may be required to make additional contingent payments based on 
developmental and sales milestones and/or royalty on future sales. As of December 31, 2023, certain milestone events have not 
yet occurred, and therefore, the Group does not have a present obligation to make the related payments in respect of the licenses. 
Such milestones are dependent on events that are outside of the control of the Group, and many of these milestone events are 
remote of occurring. As of December 31, 2023 and December 31, 2022, payments in respect of developmental milestones that are 
dependent on events that are outside the control of the Group but are reasonably possible to occur amounted to approximately 
$7,371 and $8,666, respectively. These milestone amounts represent an aggregate of multiple milestone payments depending 
on different milestone events in multiple agreements. The probability that all such milestone events will occur in the aggregate is 
remote. Payments made to license IP represent the acquisition cost of intangible assets. 

The Group was a party to certain sponsored research arrangements and is a party to arrangements with contract manufacturing 
and contract research organizations, whereby the counterparty provides the Group with research and/or manufacturing services. 
As of December 31, 2023 and 2022, the noncancellable commitments in respect of such contracts amounted to approximately 
$16,422 and $11,288, respectively.

In March 2024, a complaint was filed in Massachusetts District Court against the Group alleging breach of contract with respect to 
certain payments alleged to be owed to a previous employee of a Group subsidiary based on purported terms of a contract between 
such individual and the Group. The Group intends to defend itself vigorously though the ultimate outcome of this matter and the 
timing for resolution remains uncertain. No determination has been made that a loss, if any, arising from this matter is probable or 
that the amount of any such loss, or range of loss, is reasonably estimable.

The Group is involved from time-to-time in various legal proceedings arising in the normal course of business. Although the 
outcomes of these legal proceedings are inherently difficult to predict, the Group does not expect the resolution of such legal 
proceedings to have a material adverse effect on its financial position or results of operations. The Group did not book any 
provisions and did not identify any contingent liabilities requiring disclosure for any legal proceedings other than already included 
above for the years ended December 31, 2023 and 2022.

26.  Related Parties Transactions 

Related Party Subleases and Royalties 
During 2019, the Group executed a sublease agreement with a related party, Gelesis. As of December 31, 2022, the sublease 
receivable amounted to $1,285. During 2023, the sublease receivable was written down to $0 as Gelesis ceased operations and 
filed for bankruptcy.

The Group recorded $23, $89 and $113 of interest income with respect to the sublease during the years ended December 31, 
2023, 2022, and 2021, respectively, which is presented within finance income in the Consolidated Statement of Comprehensive 
Income/(Loss).

The Group received royalties from Gelesis on its product sales. The Group recorded zero, $509, and $231 of royalty revenue

Statement of Comprehensive Income/(Loss).

27.  Taxation continued

The income tax expense/(benefit) was $30,525, $(55,719) and $3,756 in 2023, 2022 and 2021 respectively. The increase in 
tax expense for the year ended December 31, 2023 was primarily attributable to a lower pre-tax loss in the tax consolidated 
U.S. group, the tax in respect of the sale of future royalties to Royalty Pharma and the tax impact of derecognizing previously 
recognized deferred tax assets that are no longer expected to be utilized.

Reconciliation of Effective Tax Rate
The Group is primarily subject to taxation in the U.S. A reconciliation of the U.S. federal statutory tax rate to the effective tax rate is 
as follows:

For the year ended December 31

US federal statutory rate
State taxes, net of federal effect
Tax credits
Stock-based compensation
Finance income/(costs) – fair value 
accounting
Loss with respect to associate 
for which no deferred tax asset is 
recognized
Revaluation of deferred due to rate 
change
Nondeductible compensation
Recognition of deferred tax assets and 
tax benefits not previously recognized
Unrecognized deferred tax asset
Deconsolidation of subsidiary
Other
Worthless stock deduction

The Group has recognized deferred tax assets due to future reversals of existing taxable temporary differences that will be 
sufficient to recover the deferred tax assets. Our unrecognized deferred tax assets of $88,058 are primarily related to tax 
credits, capitalized research & development expenditures and deferred tax asset related to the sale of future royalties to Royalty 
Pharma. The Group does not believe it is probable that future taxable profit will be available to support the realizability of these 
unrecognized deferred tax assets.

The Group had U.S. federal net operating losses carry forwards (“NOLs”) of $13,681, $219,466 and $215,400 as of December 
31, 2023, 2022 and 2021, respectively, which are available to offset future taxable income. These NOLs expire through 2037 with 
the exception of $2,305 which is not subject to expiration. The Group had U.S. federal research and development tax credits of 
approximately $1,396, $4,500 and $3,900 as of December 31, 2023, 2022 and 2021, respectively, which are available to offset 
future taxes that expire at various dates through 2043. The Group also had Federal Orphan Drug credits of approximately $930 
and $6,100 as of December 31, 2023, and 2022, which are available to offset future taxes that expire at various dates through 
2043. A portion of these federal NOLs and credits can only be used to offset the profits from the Group’s subsidiaries who file 
separate federal tax returns. These NOLs and credits are subject to review and possible adjustment by the Internal Revenue 
Service.

The Group had state net operating losses carry forwards (“NOLs”) of approximately $111,446, $71,700 and $27,900 for the years 
ended December 31, 2023, 2022 and 2021, respectively, which are available to offset future taxable income. These NOLs expire 
at various dates beginning in 2030. The Group had Massachusetts research and development tax credits of approximately $98, 
$600 and $1,300 for the years ended December 31, 2023, 2022 and 2021, respectively, which are available to offset future taxes 
and expire at various dates through 2038. These NOLs and credits are subject to review and possible adjustment by state taxing 
authority.

Utilization of the NOLs and research and development credit carryforwards may be subject to a substantial annual limitation under 
Section 382 of the Internal Revenue Code of 1986 due to ownership change limitations that have occurred previously or that could 
occur in the future. These ownership changes may limit the amount of NOL and research and development credit carryforwards 
that can be utilized annually to offset future taxable income and tax, respectively. The Group has performed a Section 382 analysis  
through December 31, 2023. The results of this analysis concluded that certain net operating losses were subject to limitation 
under Section 382 of the Internal Revenue Code. None of the Group’s net operating losses which are subject to a Section 382 
limitation has been recognized in the financial statements.

28.  Subsequent Events 

The Group has evaluated subsequent events after December 31, 2023, up to the date of issuance, April 25, 2024, of the 
Consolidated Financial Statements, and has not identified any recordable or disclosable events not otherwise reported in these 
Consolidated Financial Statements or notes thereto, except for the following:

In January 2024, the Group launched two new Founded Entities (Seaport Therapeutics and Gallop Oncology) to advance certain 
programs from the Wholly-Owned Programs segment. Seaport Therapeutics ("Seaport") will advance certain central nervous 
system programs and relevant Glyph intellectual property.  Gallop Oncology will advance LYT-200 and other galectin-9 intellectual 
property. The financial results of these programs were included in the Wholly-Owned Programs segment in the footnotes to the 
Consolidated Financial Statements, as of December 31, 2023 and 2022, and for the three years ended December 31, 2023, 2022 
and 2021, respectively. Upon raising dilutive third-party financing, the financial results of these two entities will be included in the 
Controlled Founded Entities segment to the extent that the Group maintains control over these entities.

On May 9, 2022, the Group announced the commencement of a $50,000 share repurchase program (the "Program") of its ordinary 
shares of one pence each. In February 2024, the Group completed the Program and has repurchased an aggregate of 20,182,863 
ordinary shares under the Program. These shares have been held as treasury shares and are being used to settle the vesting of 
restricted stock units or exercise of options.

In March 2024, Karuna was acquired by Bristol Myers Squibb (“BMS”) in accordance with a definitive merger agreement signed in 
December 2023. As a result of this transaction, the Group received total proceeds of $292,672 before income tax in exchange for 
its holding of 886,885 shares of Karuna common stock. 

In March 2024, the Group announced a proposed capital return of $100,000 to its shareholders by way of a tender offer (the 
"Tender Offer"). The Tender Offer is expected to be launched in early May, subject to market conditions and shareholder approval. 
If the full $100,000 is not returned, then the Group intends to return any remainder following the completion of the Tender Offer, 
by way of a special dividend.

In April 2024, Seaport Therapeutics, the Group's latest Founded Entity, raised $100,000 in a Series A financing, out of which 
$32,000 was invested by the Group. Following the Series A financing, the Group holds equity ownership in Seaport of 61.5 percent 
on a diluted basis. 

In April 2024, the Gelesis' Chapter 7 Trustee provided notice that a third party bid to purchase the assets subject to the bankruptcy 
had been accepted as a stalking horse bid, subject to Bankruptcy Court approval. If such sale of the assets is ultimately approved 
by the Bankruptcy Court and consummated, it is expected that PureTech could recover a portion of its investment in Gelesis senior 
secured convertible promissory notes. The ultimate resolution of this matter, any potential recovery, and the associated timing 
remain uncertain. The Group has not recorded any amount in its Consolidated Financial Statements related to amounts that may 
be received as a result of the bankruptcy process.

Notes to the Financial Statements

(amounts in thousands, except share and per share data)

1.  Accounting policies

Basis of Preparation and Measurement
The financial statements of PureTech Health plc (the “Parent”) are presented as of December 31, 2023 and 2022, and for the 
years ended December 31, 2023 and 2022, and have been prepared under the historical cost convention in accordance with 
international accounting standards in conformity with the requirements of UK-adopted International Financial Reporting Standards 
("IFRSs"). The financial statements of PureTech Health plc also comply fully with IFRSs as issued by the International Accounting 
Standards Board (IASB). A summary of the significant accounting policies that have been applied consistently throughout the year 
are set out below.

Certain amounts in the Parent Company Financial Statements and accompanying notes may not add due to rounding. All 
percentages have been calculated using unrounded amounts. 

Functional and Presentation Currency
The functional currency of the Parent is United States ("U.S.”) Dollars and the financial statements are presented in U.S. Dollars.

Investments
Investments are stated at historical cost less any provision for impairment in value, and are held for long-term investment purposes. 
Provisions are based upon an assessment of events or changes in circumstances that indicate that an impairment has occurred, 
such as the performance and/or prospects (including the financial prospects) of the investee company being significantly below 
the expectations on which the investment was based, a significant adverse change in the markets in which the investee company 
operates, or a deterioration in general market conditions.

Impairment
If there is an indication that an asset might be impaired, the Parent would perform an impairment review. An asset is impaired if 
the recoverable amount, being the higher of fair value less cost to sell and value in use, is less than its carrying amount. Value in 
use is measured based on future discounted cash flows attributable to the asset. In such cases, the carrying value of the asset is 
reduced to its recoverable amount with a corresponding charge recognized in the profit and loss statement.

Dividend Income
Dividend received from the Parent's subsidiary is recorded as dividend income in the profit and loss statement.

Financial Instruments
Currently the Parent does not enter into derivative financial instruments. Financial assets and financial liabilities are recognized and 
cease to be recognized on the basis of when the related titles pass to or from the Parent company.

Share-Based Payments
Share-based payment awards granted in subsidiaries to employees, Board of Directors and consultants to be settled in Parent's 
equity instruments are accounted for as equity-settled share-based payment transactions in accordance with IFRS 2. Restricted 
stock units granted in subsidiaries to the executives are accounted for as share-based liability awards in accordance with IFRS 
2 as they can be cash-settled at PureTech's discretion and have a history of being cash-settled. The grant date fair value of 
equity-settled share-based payment awards and the settlement date fair value of the share-based liability awards are recognized 
as an increase to the investment with a corresponding increase in equity. For equity-settled restricted stock units, the grant 
date fair value is the grant date share price. For share-based liability awards, the fair value at each reporting date is measured 
using the Monte Carlo simulation analysis considering share price volatility, risk-free rate, and other covariance of comparable 
public companies and other market data to predict distribution of relative share performance. For stock options, the fair value is 
measured using an option pricing model, which takes into account the terms and conditions of the options granted. When the 
subsidiary settles the equity awards other than by the Parent's equity, the settlement is recorded as a decrease in equity against a 
corresponding decrease to the investment account.

Notes to the Financial Statements continued

2. 

Investment in subsidiary continued

PureTech consists of the Parent and its subsidiaries (together, the “Group”). Investment in subsidiary represents the Parent’s 
investment in PureTech LLC as a result of the reverse acquisition of the Group’s financial statements immediately prior to the 
Parent’s initial public offering (“IPO”) on the London Stock Exchange in June 2015. PureTech LLC operates in the U.S. as a US-
focused scientifically-driven research and development company that conceptualizes, sources, validates and commercializes 
different approaches to advance the needs of human health. For a summary of the Parent’s indirect subsidiaries, please refer to 
Note 1 of the Consolidated Financial Statements of the Group.

The Parent recognizes in its investment in its operating subsidiary PureTech LLC, share-based payments granted to employees, 
executives, non-executive directors and service providers in its subsidiary. The decrease in 2021 and increases in investment in 
subsidiary in 2022 and 2023, respectively, are due to such share-based payments results from the expenses related to the grant of 
equity-settled share-based awards, as well as settlements and payments of these equity awards by the subsidiary, or settlement of 
share-based payments through equity by PureTech.

3.  Share capital and reserves

PureTech Health plc was incorporated with the Companies House under the Companies Act 2006 as a public company on May 8, 
2015.

On June 24, 2015, the Group authorized 227,248,008 of ordinary share capital at one pence apiece. These ordinary shares were 
admitted to the premium listing segment of the United Kingdom’s Listing Authority and traded on the Main Market of the London 
Stock Exchange for listed securities. In conjunction with the authorization of the ordinary shares, the Parent completed an IPO on 
the London Stock Exchange, in which it issued 67,599,621 ordinary shares at a public offering price of 160 pence per ordinary 
share, in consideration for $159.3 million, net of issuance costs of $11.8 million.

Additionally, the IPO included an over-allotment option equivalent to 15 percent of the total number of new ordinary shares. The 
stabilization manager provided notice to exercise in full its over-allotment option on July 2, 2015. As a result, the Parent issued 
10,139,943 ordinary shares at the offer price of 160 pence per ordinary share, which resulted in net proceeds of $24.2 million, net 
of issuance costs of $0.8 million.

On March 12, 2018, the Group raised approximately $100.0 million, before issuance costs and other expenses, by way of a placing 
of 45,000,000 placing shares.

During the years ended December 31, 2023 and 2022, other reserves increased by $3,482 and $10,384, respectively, primarily due 
to equity-settled share-based payments granted to employees, the Board of Directors and service providers in subsidiaries. See 
Note 2 above.

Treasury stock
On May 9, 2022, the Group announced the commencement of a $50,000 share repurchase program (the "Program") of its ordinary 
shares of one pence each (the “Ordinary Shares”). The Group executed the Program in two equal tranches. The Group entered 
into an irrevocable non-discretionary instruction with Jefferies International Limited (“Jefferies”) in relation to the purchase by 
Jefferies of the Ordinary Shares for an aggregate consideration (excluding expenses) of no greater than $25,000 for each tranche, 
and the simultaneous on-sale of such Ordinary Shares by Jefferies to the Group. Jefferies made its trading decisions in relation to 
the Ordinary Shares independently of, and uninfluenced by, the Group. Purchases could continue during any close period to which 
the Group was subject. The instruction to Jeffries could be amended or withdrawn so long as the Group was not in a close period 
or otherwise in possession of inside information.

Any purchases of the Ordinary Shares under the Program were carried out on the London Stock Exchange and could be carried 
out on any other UK recognized investment exchange in accordance with pre-set parameters and subject to limits prescribed by 
the Group’s general authority to repurchase the Ordinary Shares granted by its shareholders at its annual general meeting on May 
27, 2021, and relevant Rules and Regulations. All Ordinary Shares repurchased under the Program are held in treasury.

As of December 31, 2023, the Group repurchased an aggregate of 18,278,873 Ordinary Shares under the share repurchase 
program. The Program was completed during the month ended February 2024.

4. 

Intercompany payables

The Parent had a balance due to its operating subsidiary PureTech LLC of $22,061 as of December 31, 2023, which is related to 
IPO costs and operating expenses. These intercompany payables do not bear any interest and are repayable upon demand.

5.  Profit and loss account

As permitted by Section 408 of the Companies Act 2006, the Parent’s profit and loss account has not been included in these 
financial statements. The Parent’s loss for the year was $3,178. 

6.  Directors’ remuneration, employee information and share-based payments

The remuneration of the executive Directors of the Parent company is disclosed in Note 26. Related Parties Transactions, of the 
Group's Consolidated Financial Statements. Full details of Directors’ remuneration can be found in the audited sections of the 
Directors’ Remuneration Report. Full detail of the share-based payment charge and the related disclosures can be found in Note 9. 
Share-based Payments, of the Group's Consolidated Financial Statements.

The Parent had no employees during 2023 or 2022.

This Annual Report and Accounts and our associated Annual Report on 
Form 20-F include statistical and other industry and market data that we 
obtained from industry publications and research, surveys and studies 
conducted by third parties. Industry publications and third-party research, 
surveys and studies generally indicate that their information has been

Risks Related to our Financial Position and Need for Additional Capital

We are a clinical-stage biotherapeutics company and have incurred 
significant operating losses since our inception. We may continue to incur 
significant operating losses for the foreseeable future.

Investment in biotechnology, including therapeutic development and 
medical device development, is highly speculative because it entails 
substantial upfront capital expenditures and significant risk that 
any potential therapeutic candidate will be unable to demonstrate 
effectiveness or an acceptable safety profile, gain regulatory approval 
or certification (where applicable) and become commercially viable. To 
date, only two of our Founded Entities’ medical devices, Gelesis, Inc.’s 
Plenity® and Akili Interactive Labs, Inc.’s EndeavorRx®, have received 
marketing authorization from the U.S. Food and Drug Administration, 
or the FDA, and have been CE Marked in the European Union, or EU. All 
of the therapeutic candidates in our Internal Programs and the majority 
of our Founded Entities’ therapeutic candidates may require substantial 
additional development time, including extensive clinical research, and 
resources before we would be able to apply for or receive regulatory 
clearances, certifications or approvals and begin generating revenue from 
therapeutic sales.

Since our inception, we have invested most of our resources in developing 
our technology and therapeutic candidates, building our intellectual 
property portfolio, developing our supply chain, conducting business 
planning, raising capital and providing general and administrative support 
for these operations, including with respect to our Founded Entities. We 
are not operationally profitable and have incurred operating losses in 
each year since our inception. Our operating losses for the years ended 
December 31, 2021, 2022 and 2023 were $150.3 million, $197.8 million and 
$146.2 million, respectively. We have no therapeutics developed in our 
Internal Programs approved for commercial sale and have not generated 
any revenues from therapeutic sales, and we and our Founded Entities 
have financed operations solely through the sale of equity securities, 
revenue from strategic alliances and government funding and, with respect 
to certain of our Founded Entities, debt financings. We continue to incur 
significant research and development, or R&D, and other expenses related 
to ongoing operations and expect to incur losses for the foreseeable 
future. We anticipate continued losses for the foreseeable future.

Due to risks and uncertainties associated with the development of drugs, 
biologics and medical devices, we are unable to predict the timing 
or amount of our expenses, or when we will be able to generate any 
meaningful revenue or achieve or maintain profitability, if ever. In addition, 
our expenses could increase beyond our current expectations if we are 
required by the FDA, the European Medicines Agency, or the EMA, or 
other comparable foreign regulatory authorities and notified bodies in the 
EU to perform preclinical studies or clinical trials in addition to those that 
we currently anticipate, or if there are any delays in any of our or our future 
collaborators’ clinical trials or the development of our existing therapeutic 
candidates and any other therapeutic candidates that we may identify. 
Even if our existing therapeutic candidates or any future therapeutic 
candidates that we may identify are approved for commercial sale, we 
anticipate incurring significant costs associated with commercializing any 
approved therapeutic and ongoing compliance efforts.

As of December 31, 2023, we had never generated revenue from the 
therapeutic candidates within our Internal Programs, and we may never be 
operationally profitable.

We may never be able to develop or commercialize marketable 
therapeutics or achieve operational profitability. Revenue from the sale 
of any therapeutic candidate for which regulatory clearance, certification, 
authorization or approval is obtained will be dependent, in part, upon the 
size of the markets in the territories for which we gain regulatory clearance, 
certification, authorization or approval, the accepted price for the 
therapeutic, the ability to obtain reimbursement at any price and whether 

Additional informationPureTech Health plc   Annual Report and Accounts 2023    187  

we own the commercial rights for that territory. Our growth strategy 
depends on our ability to generate revenue. In addition, if the number 
of addressable patients is not as anticipated, the indication or intended 
use cleared, certified, authorized or approved by regulatory authorities 
or notified bodies is narrower than expected, or the reasonably accepted 
population for treatment is narrowed by competition, physician choice or 
treatment guidelines, we may not generate significant revenue from sales 
of such therapeutics, even if cleared, certified, authorized or approved. 
Even if we are able to generate revenue from the sale of any cleared, 
certified, authorized or approved therapeutics, we may not become 
operationally profitable and may need to obtain additional funding to 
continue operations. Even if we achieve operational profitability in the 
future, we may not be able to sustain profitability in subsequent periods.

If we are unable to achieve sustained profitability, it would depress 
the value of our company and could impair our ability to raise capital, 
expand our business, diversify our R&D pipeline, market the therapeutic 
candidates within our Internal Programs, if cleared or approved, and 
pursue or continue our operations. Our prior losses, combined with 
expected future losses, have had and may continue to have an adverse 
effect on our shareholders’ equity and working capital.

We may require substantial additional funding to achieve our business 
goals. If we are unable to obtain this funding when needed and on 
acceptable terms, we could be forced to delay, limit or terminate certain 
of our therapeutic development efforts. Certain of our Founded Entities 
will similarly require substantial additional funding to achieve their 
business goals.

Across our Internal Programs and our Founded Entities, we established 
the underlying platforms that have resulted in the development of 29 
therapeutics and therapeutic candidates, including two (Plenity and 
EndeavorRx) that have received both U.S. FDA and European marketing 
authorization and a third (KarXT) that has been filed for FDA approval. 
Developing biotherapeutics is expensive and time-consuming, and with 
respect to the therapeutic candidates within our Internal Programs, we 
expect to require substantial additional capital to conduct research, 
preclinical studies and clinical trials for our current and future programs, 
establish pilot scale and commercial scale manufacturing processes and 
facilities, seek regulatory approvals for the therapeutic candidates within 
our Internal Programs and launch and commercialize any therapeutics 
for which we receive regulatory approval, including building our own 
commercial sales, marketing and distribution organization. With respect 
to our Founded Entities’ programs, we anticipate that we will continue to 
fund a small portion of development costs by strategically participating 
in such companies’ financings when doing so would be in the interests 
of our shareholders. We expect to finance our future cash needs through 
a combination of public and private equity offerings, debt financings, 
strategic partnerships, sales of assets and alliances and licensing 
arrangements, among others. We, and indirectly, our shareholders, 
may bear the cost of issuing and servicing any such securities and of 
entering into and maintaining any such strategic partnerships or other 
arrangements. Because any decision by us to issue debt or equity 
securities in the future will depend on market conditions and other factors 
beyond our control, we cannot predict or estimate the amount, timing or 
nature of any future financing transactions. Our management and strategic 
decision makers have not made decisions regarding the future allocation 
of certain of our resources among our Founded Entities, but evaluate the 
needs and opportunities with respect to each of these Founded Entities 
routinely and on a case-by-case basis. In connection with any collaboration 
agreements relating to our Internal Programs, we are also responsible 
for the payments to third parties of expenses that may include milestone 
payments, license maintenance fees and royalties, including in the case of 
certain of our agreements with academic institutions or other companies 
from whom intellectual property rights underlying their respective 
programs have been in-licensed or acquired. Because the outcome of 
any preclinical or clinical development and regulatory approval process 
is highly uncertain, we cannot reasonably estimate the actual amounts 
necessary to successfully complete the development, regulatory approval 
or certification process and potential commercialization of our Internal 
Programs and any future therapeutic candidates we may identify.

As of December 31, 2023, we had cash, cash equivalents and short term 
investments of $326 million at the PureTech Health plc level. Based on 
current projections, the Directors believe that the company has sufficient 
available funding to extend operations into at least 2027. However, our 
operating plan may change as a result of many factors currently unknown 
to us, and we may need to seek additional funds sooner than planned, 
through public or private equity or debt financings, sales of assets or 
programs, other sources, such as strategic collaborations or license and 
development agreements, or a combination of these approaches. Even 
if we believe we have sufficient funds for our current or future operating 
plans, we may opportunistically seek additional capital if market conditions 
are favorable or if we have specific strategic considerations. Our spending 
will vary based on new and ongoing therapeutic development and 
corporate activities. 

Our future funding requirements, both short-term and long-term, will 
depend on many factors, including, but not limited to:

 — the time and cost necessary to complete ongoing, planned and future 
unplanned clinical trials (such term to include clinical studies in these 
Risk Factors where context requires and the item being studied or 
subject of a potential study may be regulated as a medical device in the 
EU), including our ongoing clinical trials for certain of our therapeutic 
candidates, and potential future clinical trials for certain of our 
therapeutic candidates;

 — the outcome, timing and cost of meeting regulatory requirements 
established by the FDA, the EMA and other comparable foreign 
regulatory authorities;

 — the progress, timing, scope and costs of our preclinical studies, clinical 
trials and other related activities for our ongoing and planned clinical 
trials, and potential future clinical trials;

 — the costs of obtaining clinical and commercial supplies of raw materials 
and drug products for the therapeutic candidates within our Internal 
Programs, as applicable, and any other therapeutic candidates we may 
identify and develop;

 — our ability to successfully identify and negotiate acceptable terms for 

third-party supply and contract manufacturing agreements with contract 
manufacturing organizations, or CMOs;

 — the costs of commercialization activities for any of the therapeutic 

candidates within our Internal Programs that receive marketing approval, 
including the costs and timing of establishing therapeutic sales, 
marketing, distribution and manufacturing capabilities, or entering 
into strategic collaborations with third parties to leverage or access 
these capabilities;

 — the amount and timing of sales and other revenues from the therapeutic 

candidates within our Internal Programs, if approved, including the 
sales price and the availability of coverage and adequate third-party 
reimbursement;

 — the cash requirements of our Founded Entities and our ability and 

willingness to provide them with financing;

 — the cash requirements of any future acquisitions or discovery of 

therapeutic candidates;

 — the time and cost necessary to respond to technological and market 

developments, including other therapeutics that may compete with one 
or more of our Internal Programs or those of our Founded Entities;

 — the costs of acquiring, licensing or investing in intellectual property 

rights, therapeutics, therapeutic candidates and businesses;

 — our ability to attract, hire and retain qualified personnel as we expand 

R&D and establish a commercial infrastructure;

 — the costs of maintaining, expanding and protecting our intellectual 

property portfolio; 

 — the costs of operating as a public company in the United Kingdom, or 
UK, and the United States, or US, and maintaining listings on both the 
London Stock Exchange, or the LSE, and The Nasdaq Global Market, 
or Nasdaq; and

 — costs associated with any adverse market conditions or other 

macroeconomic factors.

We cannot be certain that additional funding will be available on 
acceptable terms, or at all. If adequate funds are not available to us on a 
timely basis, we may be required to delay, limit or terminate one or more 
research or development programs or the potential commercialization 
of any approved therapeutics or be unable to expand operations or 
otherwise capitalize on business opportunities, as desired, which could 
materially affect our business, prospects, financial condition and results 
of operations.

Raising additional capital may cause dilution to our existing shareholders, 
restrict our operations or require us to relinquish rights to current 
therapeutic candidates or to any future therapeutic candidates on 
unfavorable terms.

To the extent that we or our Founded Entities raise additional capital 
through the sale of equity or convertible debt securities, your ownership 
interest will be diluted, and the terms may include liquidation or other 
preferences that adversely affect your rights as a shareholder. The 
incurrence of additional indebtedness would result in increased fixed 
payment obligations and could involve additional restrictive covenants, 
such as limitations on our ability to incur additional debt, limitations on 
our ability to acquire, sell or license intellectual property rights and other 
operating restrictions that could adversely impact our ability to conduct 
our business. Additionally, any future collaborations we enter into with 
third parties may provide capital in the near term, but limit our potential 
cash flow and revenue in the future. If we raise additional funds through 
strategic partnerships and alliances and licensing arrangements with third 
parties, we may have to relinquish valuable rights to our technologies or 
therapeutic candidates, or grant licenses or other rights on unfavorable 

Risk Factor Annex continuedAdditional information188    PureTech Health plc   Annual Report and Accounts 2023

terms. Any such additional fundraising efforts for us may divert our 
management from their day-to-day activities, which may adversely affect 
our ability to develop and commercialize therapeutic candidates that we 
may identify and pursue. Moreover, such financing may result in dilution to 
shareholders, imposition of debt covenants and repayment obligations, or 
other restrictions that may affect our business.

In addition, if any of our Founded Entities raises funds through the issuance 
of equity securities, our shareholders’ indirect equity interest in such 
Founded Entity could be substantially diminished. If any of our Founded 
Entities raises additional funds through collaboration and licensing 
arrangements, it may be necessary to relinquish some rights to our 
technologies or these therapeutic candidates or grant licenses on terms 
that are not favorable to us.

If we engage in acquisitions or strategic partnerships, this may increase 
our capital requirements, dilute our shareholders, cause us to incur debt or 
assume contingent liabilities and subject us to other risks.

We may engage in various acquisitions and strategic partnerships in the 
future, including licensing or acquiring complementary therapeutics, 
intellectual property rights, technologies or businesses. Any acquisition or 
strategic partnership may entail numerous risks, including:

 — increased operating expenses and cash requirements;

 — the assumption of indebtedness or contingent liabilities;

 — the issuance of our equity securities which would result in dilution to our 

shareholders;

 — assimilation of operations, intellectual property, therapeutics and 

therapeutic candidates of an acquired company, including difficulties 
associated with integrating new personnel;

 — the diversion of our management’s attention from our existing 

therapeutic programs and initiatives in pursuing such an acquisition or 
strategic partnership;

 — retention of key employees, the loss of key personnel and uncertainties in 

our ability to maintain key business relationships;

 — risks and uncertainties associated with the other party to such a 

transaction, including the prospects of that party and their existing 
therapeutics or therapeutic candidates and regulatory approvals; and

 — our inability to generate revenue from acquired intellectual property, 

technology and/or therapeutics sufficient to meet our objectives or even 
to offset the associated transaction and maintenance costs.

In addition, if we undertake such a transaction, we may issue dilutive 
securities, assume or incur debt obligations, incur large one-time expenses 
and acquire intangible assets that could result in significant future 
amortization expense.

Risks Related to Our Founded Entities

Our ability to realize value from our Founded Entities may be impacted 
if we reduce our ownership or otherwise cede control to other investors 
through contractual agreements or otherwise.

We do not have a majority interest in our Non-Controlled Founded 
Entities. Our interests may be further reduced as such companies raise 
capital from third-party investors. In addition, we may agree to contractual 
arrangements for the funding of further developments by one or more 
of our Founded Entities. As a result, with respect to our Non-Controlled 
Founded Entities, we may not be able to exercise control over the affairs 
of such Founded Entity, including that Founded Entity’s governance 
arrangements and access to management and financial information. We 
are also party to agreements with certain of our Founded Entities that 
contain provisions which could force us to exit from that Founded Entity 
at a time and/or price determined by other investor(s) (for example, by the 
exercise of drag-along rights). If we were forced to exit out of a Founded 
Entity, this could have a material adverse effect on our business, financial 
condition or results of operations and prospects. In addition, if the affairs 
of one or more Founded Entities in which we hold a minority stake were to 
be conducted in a manner detrimental to our interests or intentions, our 
business, reputation and prospects may be adversely affected.

As certain of our Founded Entities have completed equity financings, they 
have entered into certain agreements with the investors participating 
in such financings, including us. We are party to voting agreements 
with Entrega, Inc., or Entrega Sonde Health, Inc., or Sonde and Seaport 
Therapeutics, Inc. or Seaport; investors’ rights agreements with Akili, 
Vedanta, Entrega, Sonde, Seaport and Vor Biopharma Inc., or Vor, and 
stockholders’ agreements with Gelesis, Akili, Vedanta, Entrega, and Sonde, 
pursuant to which we are subject to certain restrictions on the transfer 
or sale of shares (e.g., pre-emptive rights or drag-along, tag-along rights 
or lock up agreements), and we may not be able freely to transfer our 
interest in such Founded Entities or procure the sale of the entire issued 

share capital of such Founded Entities, similar to other investors who are 
party to these agreements. In addition, many of our Founded Entities have 
employee share plans which further dilute our interest in such business. If 
the affairs of one or more of our Founded Entities were to be conducted or 
impacted in a manner detrimental to our interests or intentions the value 
we are able to realize from such entity may be diminished. For example, 
on October 30, 2023, Gelesis ceased operations and filed a voluntary 
petition for Chapter 7 bankruptcy liquidation in October 2023. If we were 
unable to realize our interest in a Founded Entity or suffer dilution of our 
shareholding, this could have a material adverse effect on our business, 
financial condition or results of operation and prospects.

Our overall value may be dominated by a single or limited number of our 
Founded Entities.

A large proportion of our overall value may at any time reside in a small 
proportion of our Founded Entities. Accordingly, there is a risk that if 
one or more of the intellectual property or commercial rights relevant to 
a valuable business were impaired, this would have a material adverse 
impact on our overall value. Furthermore, a large proportion of our 
overall revenue may at any time be the subject of one, or a small number 
of, licensed technologies. Should the relevant licenses be terminated or 
expire this would be likely to have a material adverse effect on the revenue 
received by us. Any material adverse impact on the value of the business 
of a Founded Entity could, in the situations described above, or otherwise, 
have a material adverse effect on our business, financial condition, trading 
performance and/or prospects.

We have limited information about and limited control or influence over our 
Non-Controlled Founded Entities.

While we maintain ownership of equity interests in our Non-Controlled 
Founded Entities, we do not maintain voting control or direct management 
and development efforts for these entities. Each of these entities are 
independently managed, and we do not control the clinical and regulatory 
development of these Non-Controlled Founded Entities’ therapeutic 
candidates. Any failure by our Non-Controlled Founded Entities to adhere 
to regulatory requirements, initiate preclinical studies and clinical trials 
on schedule or to obtain clearances or approvals for their therapeutic 
candidates could have an adverse effect on our business, financial 
condition, results of operation and prospects. The information included 
in this report about our Non-Controlled Founded Entities is based on 
(i) our knowledge, which may in some cases be limited, (ii) information 
that is publicly available, including the public filings of SEC reporting 
companies, such as Vor, Akili and Gelesis, and (iii) information provided to 
us by our Non-Controlled Founded Entities. Where a date is provided, the 
information included in this report about our Non-Controlled Founded 
Entities is as of that date and you should not assume that it is accurate 
as of any other date. As such, there may be developments at our Non-
Controlled Founded Entities of which we are unaware that could have an 
adverse effect on our business, financial condition, results of operation and 
prospects. For example, on October 30, 2023, Gelesis ceased operations 
and filed a voluntary petition for Chapter 7 bankruptcy liquidation in 
October 2023. 

Our Founded Entities are difficult to value given that many of their 
therapeutic candidates are in the development stage.

Investments in early-stage companies, particularly privately held entities, 
are inherently difficult to value since sales, cash flow and tangible asset 
values are very limited, which makes the valuation highly dependent on 
expectations of future development, and any future significant revenues 
would only arise in the medium to longer terms and are uncertain. Equally, 
investments in companies just commencing the commercial stage are 
also difficult to value since sales, cash flow and tangible assets are limited, 
they have only commenced initial receipts of revenues and valuations are 
still dependent on expectations of future development. There can be no 
guarantee that our valuation of our Founded Entities will be considered 
to be correct in light of the early stage of development for many of these 
entities and their future performance. As a result, we may not realize the 
full value of our ownership in such Founded Entities which could adversely 
affect our business and results of operations. For example, on November 
15, 2019, resTORbio, Inc., or resTORbio, announced that its lead therapeutic 
candidate, RTB101, did not meet its primary endpoint in its Phase 3 study 
and ceased further development leading to a decline in resTORbio’s stock 
price from $9.27 to $1.09 and our sale of 7,680,700 common shares of 
resTORbio. As a result of the foregoing, we recognized a total cash loss of 
approximately $10 million from our initial investment through sale of shares.

Risk Factor Annex continuedAdditional informationPureTech Health plc   Annual Report and Accounts 2023    189  

Certain of our and our Founded Entities’ therapeutics and therapeutic 
candidates represent novel therapeutic approaches and negative 
perception of any therapeutic or therapeutic candidate that we or they 
develop could adversely affect our ability to conduct our business, obtain 
and maintain regulatory clearance, authorization or approvals or identify 
alternate regulatory pathways to market for such therapeutic candidate.

Certain of our and our Founded Entities’ therapeutic candidates are 
considered relatively new and novel therapeutic approaches. Our and 
their success will depend upon physicians who specialize in the treatment 
of diseases targeted by our and their therapeutic candidates, prescribing 
potential treatments that involve the use of our and their therapeutic 
candidates, if approved, in lieu of, or in addition to, existing treatments 
with which they are more familiar and for which greater clinical data 
may be available. Access will also depend on consumer acceptance and 
adoption of therapeutics that are commercialized. In addition, responses 
by the U.S., state or foreign governments to negative public perception 
or ethical concerns may result in new legislation or regulations that could 
limit our or our Founded Entities’ ability to develop or commercialize 
any therapeutic candidates, obtain or maintain regulatory approval, 
identify alternate regulatory pathways to market or otherwise achieve 
profitability. More restrictive statutory regimes, government regulations 
or negative public opinion would have an adverse effect on our business, 
financial condition, results of operations and prospects and may delay or 
impair the development and commercialization of our or our Founded 
Entities’ therapeutic candidates or demand for any therapeutics we or 
they may develop.

For example, in the United States and the EU, no therapeutics to date 
have been approved specifically demonstrating an impact on the 
microbiome as part of their therapeutic effect. Vedanta is developing a 
pipeline of microbiome-derived modulators for immune and infectious 
disease. Microbiome therapies may not be successfully developed or 
commercialized or gain the acceptance of the public or the medical 
community. Additionally, adverse events, or AEs, in non-investigational 
new drug application, or IND, human clinical studies and clinical trials of 
Vedanta’s therapeutic candidates or in clinical trials of other companies 
developing similar therapeutics and the resulting publicity, similarly to the 
AEs publicized with respect to Seres Therapeutics, Inc.’s SER-287 Phase 
2 clinical trial, as well as any other AEs in the field of the microbiome, 
could result in a decrease in demand for any therapeutic that Vedanta 
may develop. Finally, the FDA, the EMA or other comparable foreign 
regulatory authorities may lack experience in evaluating the safety and 
efficacy of therapeutic candidates based on microbiome therapeutics, 
which could result in a longer than expected regulatory review process, 
increase expected development costs and delay or prevent potential 
commercialization of therapeutic candidates.

Risks Related to the Clinical Development, Regulatory Review and 
Approval of our and our Founded Entities’ Therapeutic Candidates

Risks Related to Clinical Development

The therapeutic candidates within our Internal Programs and most of 
our Founded Entities’ therapeutic candidates are in preclinical or clinical 
development, which is a lengthy and expensive process with uncertain 
outcomes and the potential for substantial delays. We cannot give any 
assurance that any of our and our Founded Entities’ therapeutic candidates 
will receive regulatory clearance, authorization or approval, which is 
necessary before they can be commercialized.

Before obtaining marketing clearance, certification, authorization or 
approval from regulatory authorities or notified bodies for the sale of 
our or our Founded Entities’ therapeutic candidates, we or our Founded 
Entities must conduct extensive clinical trials to demonstrate the safety 
and efficacy, or with respect to biologics, safety, purity and potency, 
of the therapeutic candidates in humans. To date, we have focused 
substantially all of our efforts and financial resources on identifying, 
acquiring, and developing therapeutic candidates, including conducting 
lead optimization, preclinical studies and clinical trials, and providing 
general and administrative support for these operations. To date, 
only two of our Founded Entities’ products, Gelesis’ Plenity and Akili’s 
EndeavorRx, have received marketing authorization from the FDA, 
and are CE marked in the EU, and we cannot be certain that any of our 
internal or our Founded Entities’ other therapeutic candidates will receive 
regulatory clearance, certification, authorization or approval, the timing 
of such clearance, certification, authorization or approval, if received, or 
that clinical trials will progress as planned. Our or our Founded Entities’ 
inability to successfully complete preclinical and clinical development 
could result in additional costs to us and negatively impact our ability 
to generate revenue. Our future success is dependent on our and our 
Founded Entities’ ability to successfully develop, obtain regulatory 
clearance, certification, authorization or approval for, and then successfully 

commercialize therapeutic candidates. We and our Founded Entities, with 
the exceptions of Gelesis and Akili, currently have no drugs or biologics 
approved or devices cleared, certified, authorized or approved for sale 
and have not generated any revenue from sales of drugs, biologics or 
devices. We cannot guarantee that we or our Founded Entities will be able 
in the future to develop or successfully commercialize any of our or their 
therapeutic candidates. 

Other than Gelesis’ Plenity and Akili’s EndeavorRx, all of our Internal 
Programs and our Founded Entities’ therapeutic candidates require 
additional development; management of preclinical, clinical, and 
manufacturing activities; and/or regulatory clearances, certification, 
authorization or approvals. In addition, we or our Founded Entities may 
need to obtain adequate manufacturing supply; build a commercial 
organization; commence marketing efforts; and obtain coverage 
and reimbursement before we generate any significant revenue from 
commercial therapeutic sales, if ever. Many of the therapeutic candidates 
in our Internal Programs and our Founded Entities’ therapeutic candidates 
are in early-stage research or translational phases of development, and 
the risk of failure for these programs is high. We cannot be certain that any 
of the therapeutic candidates in our Internal Programs or our Founded 
Entities’ therapeutic candidates will be successful in clinical trials or receive 
regulatory approval, authorization or clearance. Further, our Internal 
Programs or our Founded Entities’ therapeutic candidates may not receive 
regulatory clearance, certification, authorization or approval even if we 
believe they are successful in clinical trials. If we or our Founded Entities 
do not receive regulatory clearance, certification, authorization or approval 
for our or their therapeutic candidates, we may not be able to continue 
operations, which may result in dissolution, out-licensing the technology or 
pursuing an alternative strategy.

Preclinical development is uncertain. Our preclinical programs may 
experience delays or may never advance to clinical trials, which would 
adversely affect our ability to obtain regulatory clearance, authorization 
or approvals or commercialize these programs on a timely basis or at all, 
which would have an adverse effect on our business.

Certain of our Internal Programs are in the preclinical stage, and their risk 
of failure is high. Before we can commence clinical trials for a therapeutic 
candidate, we must complete extensive preclinical testing and studies 
that support our planned INDs, in the United States, or similar applications 
in other jurisdictions. We cannot be certain of the timely completion 
or outcome of our preclinical testing and studies and cannot predict 
if the FDA or other regulatory authorities will accept our proposed 
clinical programs or if the outcome of our preclinical testing and studies 
will ultimately support the further development of our programs. As a 
result, we cannot be sure that we will be able to submit INDs or similar 
applications for our preclinical programs on the timelines we expect, if at 
all, and we cannot be sure that submission of INDs or similar applications 
will result in the FDA or other regulatory authorities allowing clinical 
trials to begin.

Clinical trials of our or our Founded Entities’ therapeutic candidates may 
be delayed, and certain programs may never advance in the clinic or may 
be more costly to conduct than we anticipate, any of which can affect our 
ability to fund our company and would have a material adverse impact on 
our platform or our business.

Clinical testing is expensive, time-consuming, and subject to uncertainty. 
We cannot guarantee that any of our ongoing and planned clinical trials 
will be conducted as planned or completed on schedule, if at all. Moreover, 
even if these trials are initiated or conducted on a timely basis, issues may 
arise that could result in the suspension or termination of such clinical trials. 
A failure of one or more clinical trials can occur at any stage of testing, and 
our clinical trials may not be successful. Events that may prevent successful 
or timely initiation or completion of clinical trials include:

 — inability to generate sufficient preclinical, toxicology, or other in vivo or in 

vitro data to support the initiation or continuation of clinical trials;

 — delays in confirming target engagement, patient selection or other 

relevant biomarkers to be utilized in preclinical and clinical therapeutic 
candidate development;

 — delays in reaching a consensus with regulatory agencies as to the design 

or implementation of our clinical studies;

 — delays in reaching agreement on acceptable terms with prospective 
contract research organizations, or CROs, and clinical trial sites, the 
terms of which can be subject to extensive negotiation and may vary 
significantly among different CROs and clinical trial sites;

 — delays in identifying, recruiting and training suitable clinical investigators;

 — delays in obtaining required Institutional Review Board, or IRB, or other 
reviewing bodies approval or positive opinion at each clinical trial site;

Risk Factor Annex continuedAdditional information190    PureTech Health plc   Annual Report and Accounts 2023

 — imposition of a temporary or permanent clinical hold by regulatory 
agencies for a number of reasons, including after review of an IND 
or amendment, clinical trial application, or CTA, or amendment, 
investigational device exemption, or IDE, or supplement, or equivalent 
application or amendment; as a result of a new safety finding that 
presents unreasonable risk to clinical trial participants; or a negative 
finding from an inspection of our clinical trial operations or study sites;

 — developments in trials for other therapeutic candidates with the same 

targets or related modalities as our or our Founded Entities’ therapeutic 
candidates conducted by competitors that raise regulatory or safety 
concerns about risk to patients of the treatment, or if the FDA or similar 
foreign authorities find that the investigational protocol or plan is clearly 
deficient to meet its stated objectives;

 — difficulties in securing access to materials for the comparator arm of 

certain of our clinical trials;

 — delays in identifying, recruiting and enrolling suitable patients to 

participate in clinical trials, and delays caused by patients withdrawing 
from clinical trials or failing to return for post-treatment follow-up;

 — difficulties in finding a sufficient number of trial sites, or trial sites 

deviating from trial protocol or dropping out of a trial;

 — difficulty collaborating with patient groups and investigators;

 — failure by CROs, other third parties, or us to adhere to clinical trial 

requirements;

 — failure by CROs, other third parties, or us to perform in accordance 
with the FDA’s or any other regulatory authority’s current good 
clinical practices, or GCP, requirements, or regulatory guidelines in 
other countries;

 — occurrence of AEs or undesirable side effects or other unexpected 

characteristics associated with the therapeutic candidate that are viewed 
to outweigh its potential benefits;

 — changes in regulatory requirements and guidance that require amending 

or submitting new clinical protocols;

 — changes in the standard of care on which a clinical development plan was 

based, which may require new or additional trials;

 — the cost of clinical trials of any therapeutic candidates that we may 

identify and pursue being greater than we anticipate;

 — clinical trials of any therapeutic candidates that we may identify and 

pursue producing negative or inconclusive results, which may result in 
our deciding, or regulators requiring us, to conduct additional clinical 
trials or abandon therapeutic development programs;

 — transfer of manufacturing processes to larger-scale facilities operated by 
a CMO, or by us, and delays or failures by our CMOs or us to make any 
necessary changes to such manufacturing process;

 — delays in manufacturing, testing, releasing, validating, or importing/
exporting sufficient stable quantities of therapeutic candidates that 
we may identify for use in clinical trials or the inability to do any of the 
foregoing; and

 — factors we may not be able to control, such as current or potential 

pandemics or other events that may limit patients, principal investigators 
or staff or clinical site availability, result in clinical trial protocol deviations, 
or impact supply of our or our Founded Entities’ therapeutic candidates.

Any inability to successfully initiate or complete clinical trials could result in 
additional costs to us or impair our ability to generate revenue. In addition, 
if we make manufacturing or formulation changes to our Internal Programs, 
we may be required to or we may elect to conduct additional preclinical 
studies or clinical trials to bridge data obtained from our modified 
therapeutic candidates to data obtained from preclinical and clinical 
research conducted using earlier versions. Clinical trial delays could also 
shorten any periods during which our therapeutics have patent protection 
and may allow our competitors to bring therapeutics to market before we 
do, which could impair our ability to successfully commercialize therapeutic 
candidates and may harm our business and results of operations.

We could also encounter delays if a clinical trial is suspended or terminated 
by us, by the data safety monitoring board, or DSMB, or by the FDA or 
other comparable foreign regulatory authorities, or if the IRBs of the 
institutions in which such trials are being conducted suspend or terminate 
the participation of their clinical investigators and sites subject to their 
review. Such authorities may suspend or terminate a clinical trial due 
to a number of factors, including failure to conduct the clinical trial 
in accordance with regulatory requirements or our clinical protocols, 
inspection of the clinical trial operations or trial site by the FDA or other 
comparable foreign regulatory authorities resulting in the imposition of 
a clinical hold, unforeseen safety issues or adverse side effects, failure 
to demonstrate a benefit from using a therapeutic candidate, changes in 
governmental regulations or administrative actions or lack of adequate 
funding to continue the clinical trial.

Moreover, principal investigators for our clinical trials may serve as scientific 
advisors or consultants to us from time to time and receive compensation 
in connection with such services. Under certain circumstances, we may be 
required to report some of these relationships to the FDA or comparable 
foreign regulatory authorities. The FDA or comparable foreign regulatory 
authority may conclude that a financial relationship between us and 
a principal investigator has created a conflict of interest or otherwise 
affected interpretation of the study. The FDA or comparable foreign 
regulatory authority may therefore question the integrity of the data 
generated at the applicable clinical trial site and the utility of the clinical 
trial itself may be jeopardized. This could result in a delay in approval, or 
rejection, of our marketing applications by the FDA or comparable foreign 
regulatory authority, as the case may be, and may ultimately lead to the 
denial of marketing approval of one or more of our Internal Programs or our 
Founded Entities’ therapeutic candidates.

Delays in the initiation, conduct or completion of any clinical trial of the 
therapeutic candidates within our Internal Programs or our Founded 
Entities’ therapeutic candidates will increase our costs, slow down the 
therapeutic candidate development and approval process and delay or 
potentially jeopardize our ability to commence therapeutic sales and 
generate revenue. In addition, many of the factors that cause, or lead to, 
a delay in the commencement or completion of clinical trials may also 
ultimately lead to the denial of regulatory approval of the therapeutic 
candidates within our Internal Programs or our Founded Entities’ 
therapeutic candidates. In the event we identify any additional therapeutic 
candidates to pursue, we cannot be sure that submission of an IDE, IND, 
CTA, or equivalent application, as applicable, will result in the FDA or 
comparable foreign regulatory authority allowing clinical trials to begin 
in a timely manner, if at all. Any of these events could have a material 
adverse effect on our business, prospects, financial condition and results 
of operations.

In addition, the FDA’s and other regulatory authorities’ policies with 
respect to clinical trials may change and additional government regulations 
may be enacted. For instance, the regulatory landscape related to clinical 
trials in the EU recently evolved. The EU Clinical Trials Regulation, or 
CTR, which was adopted in April 2014 and repeals the EU Clinical Trials 
Directive, became applicable on January 31, 2022. While the EU Clinical 
Trials Directive required a separate clinical trial application, or CTA, to 
be submitted in each member state in which the clinical trial takes place, 
to both the competent national health authority and an independent 
ethics committee, the CTR introduces a centralized process and only 
requires the submission of a single application for multicenter trials. The 
CTR allows sponsors to make a single submission to both the competent 
authority and an ethics committee in each member state, leading to a 
single decision per member state. The assessment procedure of the 
CTA has been harmonized as well, including a joint assessment by all 
member states concerned, and a separate assessment by each member 
state with respect to specific requirements related to its own territory, 
including ethics rules. Each member state’s decision is communicated 
to the sponsor via the centralized EU portal. Once the CTA is approved, 
clinical study development may proceed. The CTR foresees a three-year 
transition period. The extent to which ongoing and new clinical trials will 
be governed by the CTR varies. Clinical trials for which an application was 
submitted (i) prior to January 31, 2022 under the EU Clinical Trials Directive, 
or (ii) between January 31, 2022 and January 31, 2023 and for which the 
sponsor has opted for the application of the EU Clinical Trials Directive 
remain governed by said Directive until January 31, 2025. After this date, 
all clinical trials (including those which are ongoing) will become subject 
to the provisions of the CTR. Compliance with the CTR requirements by 
us and our third-party service providers, such as CROs, may impact our 
developments plans. 

It is currently unclear to what extent the UK will seek to align its regulations 
with the EU. The UK regulatory framework in relation to clinical trials is 
derived from existing EU legislation (as implemented into UK law, through 
secondary legislation), and after Brexit, EU laws on clinical trials (including 
the (EU) CTR) are not directly applicable in Great Britain (i.e., the UK 
excluding Northern Ireland). On January 17, 2022, the UK Medicines and 
Healthcare products Regulatory Agency, or MHRA, launched an eight-
week consultation on reframing the UK legislation for clinical trials, with 
the aim to streamline clinical trials approvals, enable innovation, enhance 
clinical trials transparency, enable greater risk proportionality, and promote 
patient and public involvement in clinical trials. The MHRA published 
its consultation outcome on March 21, 2023 in which it confirmed that it 
would update the existing legislation. The resulting legislative changes 
will ultimately determine the extent to which the UK regulations align 
with the CTR. Under the terms of the Protocol on Ireland and Northern 
Ireland, provisions of the CTR which relate to the manufacture and import 
of investigational medicinal products and auxiliary medicinal products 
currently apply in Northern Ireland.

The results of early-stage clinical trials and preclinical studies may not be 
predictive of future results. Initial data in clinical trials may not be indicative 
of results obtained when these trials are completed or in later stage trials.

 — Furthermore, our or our collaborators’ ability to successfully initiate, 

enroll and conduct a clinical trial outside the United States is subject to 
numerous additional risks, including:

The results of preclinical studies may not be predictive of the results of 
clinical trials, and the results of any early-stage clinical trials we commence 
may not be predictive of the results of the later-stage clinical trials. The 
results of preclinical studies and clinical trials in one set of patients or 
disease indications, or from preclinical studies or clinical trials that we 
did not lead, may not be predictive of those obtained in another. In some 
instances, there can be significant variability in safety or efficacy results 
between different clinical trials of the same therapeutic candidate due 
to numerous factors, including changes in trial procedures set forth in 
protocols, differences in the size and type of the patient populations, 
changes in and adherence to the dosing regimen and other clinical trial 
protocols and the rate of dropout among clinical trial participants. In 
addition, preclinical and clinical data are often susceptible to various 
interpretations and analyses, and many companies that have believed 
their therapeutic candidates performed satisfactorily in preclinical studies 
and clinical trials have nonetheless failed to obtain marketing approval. 
A number of companies in the pharmaceutical, biopharmaceutical and 
biotechnology industries have suffered significant setbacks in clinical 
development even after achieving promising results in earlier studies, 
and any such setbacks in our clinical development could have a material 
adverse effect on our business and operating results. Even if early-stage 
clinical trials are successful, we may need to conduct additional clinical 
trials of our Internal Programs in additional patient populations or under 
different treatment conditions before we are able to seek approvals 
or clearances from the FDA or other comparable foreign regulatory 
authorities to market and sell these therapeutic candidates. Our failure 
to obtain marketing authorization for the therapeutic candidates within 
our Internal Programs would substantially harm our business, prospects, 
financial condition and results of operations.

If we encounter difficulties enrolling patients in clinical trials, our clinical 
development activities could be delayed or otherwise adversely affected.

Identifying and qualifying trial participants to participate in clinical studies 
is critical to our success. The timing of our clinical studies depends on the 
speed at which we can recruit trial participants to participate in testing the 
therapeutic candidates within our Internal Programs. Delays in enrollment 
may result in increased costs or may affect the timing or outcome of the 
planned clinical trials, which could prevent completion of these trials and 
adversely affect our ability to advance the development of the therapeutic 
candidates within our Internal Programs. If trial participants are unwilling 
to participate in our studies because of negative publicity from AEs in 
our trials or other trials of similar therapeutics, or those related to specific 
therapeutic area, or for other reasons, including competitive clinical studies 
for similar patient populations, the timeline for recruiting trial participants, 
conducting studies, and obtaining regulatory approval of potential 
therapeutics may be delayed. Any delays could result in increased costs, 
delays in advancing our therapeutic candidate development, delays in 
testing the effectiveness of the therapeutic candidates within our Internal 
Programs, or termination of the clinical studies altogether.

We may not be able to identify, recruit and enroll a sufficient number of trial 
participants, or those with required or desired characteristics to achieve 
diversity in a study, to complete our clinical studies in a timely manner. 
Patient and subject enrollment is affected by factors including:

 — the size and nature of a patient population;

 — the patient eligibility criteria defined in the applicable clinical trial 
protocols, which may limit the patient populations eligible for 
clinical trials to a greater extent than competing clinical trials for the 
same indication;

 — the size of the study population required for analysis of the trial’s 

primary endpoints;

 — the severity of the disease under investigation;

 — the proximity of patients to a trial site;

 — the inclusion and exclusion criteria for the trial in question;

 — the design of the trial protocol;

 — the ability to recruit clinical trial investigators with the appropriate 

competencies and experience;

 — the availability and efficacy of approved medications or therapies for the 

disease or condition under investigation;

 — clinicians’ and patients’ perceptions as to the potential advantages and 
side effects of the therapeutic candidate being studied in relation to 
other available therapies and therapeutic candidates;

 — the ability to obtain and maintain patient consents; and

 — the risk that patients enrolled in clinical trials will not complete such trials, 

for any reason.

 — difficulty in establishing or managing relationships with CROs 

and physicians;

 — differing standards for the conduct of clinical trials;

 — differing standards of care for patients with a particular disease;

 — an inability to locate qualified local consultants, physicians and 

partners; and

 — the potential burden of complying with a variety of foreign laws, medical 

standards and regulatory requirements, including the regulation of 
pharmaceutical and biotechnology therapeutics and treatments.

If we have difficulty enrolling sufficient numbers of patients to conduct 
clinical trials as planned, we may need to delay or terminate clinical trials, 
either of which would have an adverse effect on our business.

Use of the therapeutic candidates within our Internal Programs or the 
therapeutic candidates being developed by our Founded Entities could be 
associated with side effects, AEs or other properties or safety risks, which 
could delay or halt their clinical development, prevent their regulatory 
clearance, authorization or approval, cause us to suspend or discontinue 
clinical trials, abandon a therapeutic candidate, limit their commercial 
potential, if cleared, authorized or approved, or result in other significant 
negative consequences that could severely harm our business, prospects, 
operating results and financial condition.

As is the case with pharmaceuticals generally, it is likely that there may 
be side effects and AEs associated with our and our Founded Entities’ 
drug or biologic therapeutic candidates’ use. Similarly, investigational 
devices may also be subject to side effects and AEs. Results of our clinical 
trials or those being conducted by Founded Entities could reveal a high 
and unacceptable severity and prevalence of side effects or unexpected 
characteristics. Undesirable side effects caused by these therapeutic 
candidates could cause us, our Founded Entities or regulatory authorities 
to interrupt, delay or halt clinical trials and could result in more restrictive 
labeling or the delay or denial of regulatory clearance, certification, 
authorization or approval by the FDA, the EMA or other comparable 
foreign regulatory authorities, or notified bodies (when applicable). The 
side effects related to the therapeutic candidate could affect patient 
recruitment or the ability of enrolled patients to complete the trial or result 
in potential product liability claims. Any of these occurrences may harm our 
business, financial condition and prospects significantly.

Moreover, if therapeutic candidates within our Internal Programs are 
associated with undesirable side effects in preclinical studies or clinical 
trials or have characteristics that are unexpected, we may elect to 
abandon their development or limit their development to more narrow 
uses or subpopulations in which the undesirable side effects or other 
characteristics are less prevalent, less severe or more acceptable from 
a risk-benefit perspective, which may limit the commercial expectations 
for the therapeutic candidate if approved. We may also be required to 
modify or terminate our study plans based on findings in our preclinical 
studies or clinical trials. Many therapeutic candidates that initially show 
promise in early-stage testing may later be found to cause side effects that 
prevent further development. As we work to advance existing therapeutic 
candidates and to identify new therapeutic candidates, we cannot be 
certain that later testing or trials of therapeutic candidates that initially 
showed promise in early testing will not be found to cause similar or 
different unacceptable side effects that prevent their further development.

It is possible that as we test the therapeutic candidates within our Internal 
Programs in larger, longer and more extensive clinical trials, or as the 
use of these therapeutic candidates becomes more widespread if they 
receive regulatory clearance or approval, illnesses, injuries, discomforts 
and other AEs that were observed in earlier trials, as well as conditions 
that did not occur or went undetected in previous trials, will be reported 
by subjects. If such side effects become known later in development 
or upon approval, if any, such findings may harm our business, financial 
condition and prospects significantly. Additionally, adverse developments 
in clinical trials of pharmaceutical, biopharmaceutical or biotechnology 
therapeutics conducted by others may cause the FDA or other regulatory 
oversight bodies to suspend or terminate our clinical trials or to change the 
requirements for approval of any of our Internal Programs.

In addition to side effects caused by the therapeutic candidate, the 
administration process or related procedures also can cause adverse side 
effects. If any such AEs occur, our clinical trials could be suspended or 
terminated. If we are unable to demonstrate that any AEs were not caused 
by the therapeutic candidate, the FDA, the European Commission, the 
EMA, or other regulatory authorities or bodies could order us to cease 
further development of, or deny clearance, certification or approval of, 
a therapeutic candidate for any or all targeted indications. Even if we 

Risk Factor Annex continuedAdditional information192    PureTech Health plc   Annual Report and Accounts 2023

can demonstrate that all future serious adverse events, or SAEs, are not 
therapeutic-related, such occurrences could affect patient recruitment or 
the ability of enrolled patients to complete the trial. Moreover, if we elect, 
or are required, to not initiate, delay, suspend or terminate any future 
clinical trial of any of our Internal Programs, the commercial prospects of 
such therapeutic candidates may be harmed and our ability to generate 
therapeutic revenues from any of these therapeutic candidates may be 
delayed or eliminated. Any of these occurrences may harm our ability 
to develop other therapeutic candidates, and may harm our business, 
financial condition and prospects significantly.

Additionally, if any of the therapeutic candidates within our Internal 
Programs or those of our Founded Entities receives marketing 
authorization, the FDA could impose contraindications or a boxed 
warning in the labeling of the therapeutic. For any of our drug or biologic 
therapeutic candidates receiving marketing authorization, the FDA could 
require us to adopt a risk evaluation and mitigation strategy, or REMS, 
and could apply elements to assure safe use to ensure that the benefits 
of the therapeutic outweigh its risks, which may include, among other 
things, a Medication Guide outlining the risks of the therapeutic for 
distribution to patients, a requirement that clinicians or health care settings 
to become certified prior to prescribing and to participate in additional 
REMS activities, such as training, patient counseling, and monitoring, and 
a communication plan to health care practitioners. Furthermore, if we or 
others later identify undesirable side effects caused by the therapeutic 
candidates within our Internal Programs or those of our Founded Entities, 
once approved, cleared, certified, or authorized, several potentially 
significant negative consequences could result, including:

 — regulatory authorities may suspend or withdraw approvals of such 

therapeutic candidate, or seek an injunction against its manufacture or 
distribution;

 — regulatory authorities may require additional warnings in the labeling, 

including boxed warnings, or issue safety alerts, Dear Healthcare 
Provider letters, press releases or other communications containing 
warnings or other safety information about the therapeutic;

 — we or our Founded Entities may be required by the FDA to implement a 
REMS for a marketed drug or biologic or similar risk mitigation measures 
by foreign regulatory authorities;

 — we or our Founded Entities may be required to change the way a 

therapeutic candidate is administered or conduct additional clinical trials;

 — we or our Founded Entities may be subject to fines, injunctions or the 

imposition of civil or criminal penalties;

 — we or our Founded Entities could be sued and held liable for harm 

caused to patients; and

 — our or our Founded Entities’ reputations may suffer.

Any of these occurrences could prevent us or our Founded Entities from 
achieving or maintaining market acceptance of the particular therapeutic 
candidate, if approved, authorized, cleared, or certified, and may harm our 
business, financial condition and prospects significantly.

Risks Related to Regulatory Review and Approval 

Our clinical trials may fail to demonstrate substantial evidence of the 
safety and effectiveness of therapeutic candidates that we may identify 
and pursue for their intended uses, which would prevent, delay or limit the 
scope of regulatory clearance, certification, authorization or approval and 
potential commercialization.

Before obtaining regulatory approvals for the commercial sale of any of 
our drug or biological therapeutic candidates, we must demonstrate 
through lengthy, complex and expensive preclinical studies and clinical 
trials that the applicable therapeutic candidate is both safe and effective 
for use in each target indication, and in the case of our Internal Programs 
and Founded Entities’ therapeutic candidates regulated as biological 
therapeutics in the United States, that the therapeutic candidate is safe, 
pure and potent for use in its targeted indication. Each therapeutic 
candidate must demonstrate an adequate risk versus benefit profile in 
its intended patient population and for its intended use. Similarly, before 
obtaining regulatory clearances, certifications, authorization or approvals 
for the commercial sale of any of the device therapeutic candidates of our 
Founded Entities, our Founded Entities may be required to demonstrate 
through lengthy, complex and expensive preclinical studies and clinical 
trials that the applicable therapeutic candidate meets the regulatory 
standard of clearance, certification, authorization or approval—for 
example, substantial equivalence to a predicate medical device or a 
reasonable assurance of safety or effectiveness, as applicable—for 
its intended use.

Clinical testing is expensive and can take many years to complete, and its 
outcome is inherently uncertain. Failure can occur at any time during the 
clinical development process. Most therapeutic candidates that begin 
clinical trials are never approved by regulatory authorities or notified 
bodies for commercialization. We may be unable to design and execute a 
clinical trial to support marketing authorization or certification.

We cannot be certain that our clinical trials will be successful. Additionally, 
any safety concerns observed in any one of our clinical trials in our 
targeted indications could limit the prospects for regulatory clearances, 
certification, authorization or approval of our therapeutic candidates in 
those and other indications, which could have a material adverse effect 
on our business, financial condition and results of operations. In addition, 
even if such clinical trials are successfully completed, we cannot guarantee 
that the FDA, the EMA or comparable foreign regulatory authorities or 
notified bodies (when applicable) will interpret the results as we do, and 
more trials could be required before we submit our therapeutic candidates 
for clearance, certification or approval. Even if we believe that our and 
our Founded Entities’ clinical trials and preclinical studies demonstrate 
the safety and efficacy of our and their therapeutic candidates, only the 
FDA and other comparable regulatory agencies may ultimately make such 
determination. No regulatory agency has made any such determination 
that any of our Internal Programs or those of our Founded Entities are safe 
or effective for use for any indication.

Additionally, we may utilize an “open-label” trial design for some of our 
future clinical trials. An open-label trial is one where both the patient and 
investigator know whether the patient is receiving the test article or either 
an existing approved drug or placebo. Open-label trials are subject to 
various limitations that may exaggerate any therapeutic effect as patients 
in open-label studies are aware that they are receiving treatment. Open-
label trials may be subject to a “patient bias” where patients perceive their 
symptoms to have improved merely due to their awareness of receiving 
an experimental treatment. Patients selected for early clinical studies 
often include the most severe sufferers and their symptoms may have 
been bound to improve notwithstanding the new treatment. In addition, 
open-label trials may be subject to an “investigator bias” where those 
assessing and reviewing the physiological outcomes of the clinical trials 
are aware of which patients have received treatment and may interpret the 
information of the treated group more favorably given this knowledge. 
The opportunity for bias in clinical trials as a result of open-label design 
may not be adequately handled and may cause any of our trials that utilize 
such design to fail or to be considered inadequate and additional trials 
may be necessary to support future marketing applications. Moreover, 
results acceptable to support approval in one jurisdiction may be deemed 
inadequate by another regulatory authority to support regulatory approval 
in that other jurisdiction. To the extent that the results of the trials are 
not satisfactory to the FDA, the EMA or comparable foreign regulatory 
authorities for support of a marketing application, we may be required to 
expend significant resources, which may not be available to us, to conduct 
additional trials in support of potential approval of our Internal Programs. 
Even if regulatory approval is secured for a therapeutic candidate, 
the terms of such approval may limit the scope and use of the specific 
therapeutic candidate, which may also limit its commercial potential.

Even if we complete the necessary preclinical studies and clinical trials, 
the marketing approval and certification process is expensive, time-
consuming and uncertain and may prevent us from obtaining clearance, 
certification, authorization or approvals for the potential commercialization 
of therapeutic candidates.

Any therapeutic candidate we may develop and the activities associated 
with their development and potential commercialization, including 
their design, testing, manufacture, safety, efficacy, recordkeeping, 
labeling, storage, approval, certification, advertising, promotion, sale 
and distribution, are subject to comprehensive regulation by the FDA 
and other comparable foreign regulatory authorities. Failure to obtain 
marketing authorization or certification for a therapeutic candidate will 
prevent us from commercializing the therapeutic candidate in a given 
jurisdiction. For example, although Gelesis and Akili have received 
marketing authorization for Plenity and EndeavorRx, respectively, from the 
FDA, and are CE marked in the EU, we and our Founded Entities have not 
received clearance, certification, authorization or approval to market any 
of our or their other therapeutic candidates from regulatory authorities 
in any jurisdiction and it is possible that none of the other therapeutic 
candidates we and our Founded Entities may seek to develop in the future 
will ever obtain regulatory clearance, authorization or approval. We have 
no experience in filing and supporting the applications necessary to gain 
marketing clearance, certification, authorization or approval and expect 
to rely on third-party CROs or regulatory consultants to assist us in this 
process. Securing regulatory clearance, certification, authorization or 
approval requires the submission of extensive preclinical and clinical data 
and supporting information to the various regulatory authorities for each 
therapeutic indication to establish the therapeutic candidate’s safety, 

Risk Factor Annex continuedAdditional informationPureTech Health plc   Annual Report and Accounts 2023    193  

purity, efficacy and potency. Securing regulatory clearance, authorization 
or approval also requires the submission of information about the 
therapeutic manufacturing process to, and inspection of manufacturing 
facilities by, the relevant regulatory authority. Any therapeutic candidates 
we or our Founded Entities develop may not be effective, may be only 
moderately effective, or may prove to have undesirable or unintended side 
effects, toxicities or other characteristics that may preclude our obtaining 
marketing clearance, certification, authorization or approval or prevent or 
limit commercial use, if cleared, certified, authorized or approved.

The process of obtaining marketing clearance, certification, authorization 
or approval, both in the United States and abroad, is expensive, may 
take many years if additional clinical trials are required, if clearance, 
certification, authorization or approval is obtained at all, and can 
vary substantially based upon a variety of factors, including the type, 
complexity and novelty of the therapeutic candidates involved. Changes 
in marketing authorization policies during the development period, 
changes in or the enactment of additional statutes or regulations, or 
changes in regulatory review for each submitted therapeutic application, 
may cause delays in the clearance, authorization, approval or rejection of 
an application. The FDA, comparable authorities and notified bodies in 
other countries have substantial discretion in the approval and certification 
process and may refuse to accept any application or may decide that 
our data are insufficient for clearance, authorization or approval and 
require additional preclinical, clinical or other studies. In addition, 
varying interpretations of the data obtained from preclinical and clinical 
testing could delay, limit, or prevent marketing approval or certification 
of a therapeutic candidate. Any marketing approval or certification we 
ultimately obtain may be limited or subject to restrictions or post-market 
commitments that render the cleared, certified, authorized or approved 
therapeutic not commercially viable.

If we experience delays in obtaining clearance, certification, authorization 
or approval or if we fail to obtain clearance, certification, authorization or 
approval of any therapeutic candidates we may develop, the commercial 
prospects for those therapeutic candidates may be harmed, and our ability 
to generate revenues will be materially impaired.

We have conducted, and may continue to conduct in the future, clinical 
trials for therapeutic candidates outside the United States, and the FDA, 
the EMA and comparable foreign regulatory authorities may not accept 
data from such trials.

We have conducted clinical trials outside of the United States in the past, 
and may in the future choose to conduct one or more clinical trials outside 
the United States, including in Europe. For example, we have conducted 
clinical trials in Australia and are conducting or may conduct clinical trials in 
additional locations outside the United States, including without limitation 
Argentina, Australia, Brazil, Bulgaria, Chile, Colombia, Czech Republic, 
Finland, Georgia, Greece, India, Malaysia, Mexico, Moldova, Philippines, 
Poland, Romania, Spain, South Africa, South Korea, Thailand, Ukraine, 
and the United Kingdom. The acceptance of study data from clinical trials 
conducted outside the United States or another jurisdiction by the FDA, 
the EMA or any comparable foreign regulatory authority may be subject 
to certain conditions or may not be accepted at all. For example, in cases 
where data from foreign clinical trials are intended to serve as the basis for 
approval of a drug or biologic in the United States, the FDA will generally 
not approve the application on the basis of foreign data alone unless (i) the 
data are applicable to the U.S. population and U.S. medical practice; (ii) the 
trials were performed by clinical investigators of recognized competence 
and pursuant to GCP regulations; and (iii) if necessary, the FDA is able 
to validate the data through an on-site inspection or other appropriate 
means. In addition, even where the foreign study data are not intended to 
serve as the sole basis for approval, if the study was not otherwise subject 
to an IND, the FDA will not accept the data as support for an application 
for marketing approval unless the study was conducted in accordance with 
GCP requirements and unless the FDA is able to validate the data from 
the study through an onsite inspection if deemed necessary. Many foreign 
regulatory authorities have similar approval requirements. In addition, such 
foreign trials would be subject to the applicable local laws of the foreign 
jurisdictions where the trials are conducted. There can be no assurance 
that the FDA, the EMA or any comparable foreign regulatory authority 
will accept data from trials conducted outside of the United States or the 
applicable jurisdiction. If the FDA, the EMA or any comparable foreign 
regulatory authority does not accept such data, it would result in the 
need for additional trials, which would be costly and time-consuming and 
delay aspects of our business plan, and which may result in therapeutic 
candidates that we may develop not receiving approval, authorization or 
clearance for commercialization in the applicable jurisdiction.

If we are unable to obtain regulatory clearance, certification, authorization 
or approval in one or more jurisdictions for any therapeutic candidates that 
we may identify and develop, our business could be substantially harmed.

We cannot commercialize a therapeutic until the appropriate regulatory 
authorities or notified bodies have reviewed and cleared, certified, 
authorized or approved the therapeutic candidate. Clearance, certification, 
authorization or approval by the FDA, the EMA and comparable foreign 
regulatory authorities and notified bodies is lengthy and unpredictable, 
and depends upon numerous factors, including substantial discretion of 
the regulatory authorities and notified bodies. Clearance, certification, 
authorization or approval policies, regulations, or the type and amount 
of preclinical or clinical data necessary to gain clearance, authorization 
or approval may change during the course of a therapeutic candidate’s 
development and may vary among jurisdictions, which may cause delays 
in the clearance, certification, authorization or approval or the decision 
not to clear, certify, authorize or approve an application. Gelesis and 
Akili have obtained marketing authorization from the FDA for Plenity and 
EndeavorRx, and are CE marked, respectively, but we and our Founded 
Entities have not obtained regulatory clearance, authorization or approval 
for any other therapeutic candidates, and it is possible that our current 
therapeutic candidates and any other therapeutic candidates which we and 
our Founded Entities may seek to develop in the future will not ever obtain 
regulatory clearance, certification, authorization or approval. We cannot 
be certain that any of our Internal Programs or our Founded Entities’ 
therapeutic candidates will receive regulatory clearance, certification, 
authorization or approval or be successfully commercialized even if 
we or our Founded Entities receive regulatory clearance, certification, 
authorization or approval.

Obtaining marketing clearance, certification, authorization or approval 
is an extensive, lengthy, expensive and inherently uncertain process, 
and regulatory authorities and notified bodies may delay, limit or deny 
clearance, certification, authorization or approval of the therapeutic 
candidates within our Internal Programs or our Founded Entities’ 
therapeutic candidates for many reasons, including but not limited to:

 — the inability to demonstrate to the satisfaction of the FDA, the EMA 
or comparable foreign regulatory authorities that the applicable 
therapeutic candidate is safe, pure, potent or effective as a treatment for 
our targeted indications or otherwise meets the applicable regulatory 
standards for clearance, authorization or approval;

 — the FDA, the EMA or comparable foreign regulatory authorities may 
disagree with the design, endpoints or implementation of our or our 
Founded Entities’ clinical trials;

 — the population studied in the clinical program may not be sufficiently 

broad or representative to assure safety or efficacy in the full population 
for which we or our Founded Entities seek clearance, authorization 
or approval;

 — the FDA, the EMA or comparable foreign regulatory authorities may 

require additional preclinical studies or clinical trials beyond those that 
we or our Founded Entities currently anticipate;

 — the FDA, the EMA or comparable foreign regulatory authorities may 

disagree with our or our Founded Entities’ interpretation of data from 
preclinical studies or clinical trials;

 — the data collected from clinical trials of therapeutic candidates that we 

may identify and pursue may not be sufficient to support the submission 
of an NDA, biologics license application, or BLA, or other submission 
for regulatory clearance, authorization or approval in the United States 
or elsewhere;

 — as applicable, we or our Founded Entities may be unable to demonstrate 
to the FDA, the EMA or comparable foreign regulatory authorities that 
a therapeutic candidate’s risk-benefit ratio for its proposed indication 
is acceptable;

 — the FDA, the EMA or comparable foreign regulatory authorities may 

identify deficiencies in the manufacturing processes, test procedures and 
specifications, or facilities of third-party manufacturers with which we or 
our Founded Entities contract for clinical and commercial supplies; and

 — the clearance, certification, authorization or approval policies or 

regulations of the FDA, the EMA or comparable foreign regulatory 
authorities may change in a manner that renders the clinical trial design 
or data insufficient for clearance or approval.

The lengthy approval process, as well as the unpredictability of the results 
of clinical trials and evolving regulatory requirements, may result in our or 
our Founded Entities’ failure to obtain regulatory clearance, certification, 
authorization or approval to market therapeutic candidates that we or our 
Founded Entities may pursue in the United States or elsewhere, which 
would significantly harm our or our Founded Entities’ business, prospects, 
financial condition and results of operations.

Risk Factor Annex continuedAdditional information194    PureTech Health plc   Annual Report and Accounts 2023

Furthermore, clearance, authorization or approval by the FDA in the 
United States, if obtained, does not ensure approval or certification 
by regulatory authorities or notified bodies in other countries or 
jurisdictions. To market any therapeutics outside of the United States, 
we or our Founded Entities must establish and comply with numerous 
and varying regulatory requirements of other countries regarding safety 
and effectiveness. Clinical trials conducted in one country may not be 
accepted by regulatory authorities or notified bodies in other countries, 
and regulatory approval or certification in one country does not mean that 
regulatory approval or certification will be obtained in any other country. 
Approval and certification processes vary among countries and can involve 
additional therapeutic testing and validation and additional or different 
administrative review periods from those in the United States, including 
additional preclinical studies or clinical trials, as clinical trials conducted in 
one jurisdiction may not be accepted by regulatory authorities or notified 
bodies in other jurisdictions. In many jurisdictions outside the United 
States, a therapeutic candidate must be approved for reimbursement 
before it can be approved for sale in that jurisdiction. In some cases, 
the price that we intend to charge for our therapeutics is also subject 
to approval. Seeking foreign regulatory approval or certification could 
result in difficulties and costs for us or our Founded Entities and require 
additional preclinical studies or clinical trials which could be costly and 
time-consuming. Regulatory requirements can vary widely from country 
to country and could delay or prevent the introduction of our or our 
Founded Entities’ therapeutics in those countries. The foreign regulatory 
approval and certification process involves all of the risks associated 
with FDA approval. We do not have any therapeutics approved for sale 
in international markets, though two of our Founded Entities, Akili and 
Gelesis, do. If we or our Founded Entities fail to comply with regulatory 
requirements in international markets or to obtain and maintain required 
approvals, or if regulatory approvals or certifications in international 
markets are delayed, our target market will be reduced and our ability to 
realize the full market potential of our therapeutics will be harmed.

If the FDA does not conclude that our therapeutic candidates satisfy the 
requirements for the Section 505(b)(2) regulatory approval pathway, or if 
the requirements for such therapeutic candidates under Section 505(b)
(2) are not as we expect, the approval pathway for those therapeutic 
candidates will likely take significantly longer, cost significantly more and 
entail significantly greater complications and risks than anticipated, and in 
either case may not be successful.

We plan to develop one or more therapeutic candidates for which we 
may plan to seek approval under the 505(b)(2) regulatory pathway. The 
Drug Price Competition and Patent Term Restoration Act of 1984, also 
known as the Hatch-Waxman Act, added Section 505(b)(2) to the FDCA. 
Section 505(b)(2) permits the filing of an NDA where at least some of 
the information required for approval comes from studies that were not 
conducted by or for the applicant and for which the applicant has not 
obtained a right of reference. Section 505(b)(2), if applicable to us under 
the FDCA, would allow an NDA we submit to the FDA to rely in part on data 
in the public domain or the FDA’s prior conclusions regarding the safety 
and effectiveness of approved compounds, which could expedite the 
development program for our future therapeutic candidates by potentially 
decreasing the amount of nonclinical and/or clinical data that we would 
need to generate in order to obtain FDA approval. 

If the FDA does not allow us to pursue the Section 505(b)(2) regulatory 
pathway as anticipated, we may need to conduct additional nonclinical 
studies and/or clinical trials, provide additional data and information, and 
meet additional standards for regulatory approval. If this were to occur, 
the time and financial resources required to obtain FDA approval for such 
therapeutic candidates, and complications and risks associated with such 
therapeutic candidates, would likely substantially increase. Moreover, 
inability to pursue the Section 505(b)(2) regulatory pathway could result 
in new competitive products reaching the market more quickly than any 
therapeutic candidates we developed, which could adversely impact our 
competitive position and prospects. Even if we are allowed to pursue 
the Section 505(b)(2) regulatory pathway, we cannot assure you that any 
therapeutic candidates we develop will receive the requisite approval for 
commercialization.

In addition, notwithstanding the approval of a number of products by the 
FDA under Section 505(b)(2), certain pharmaceutical companies and others 
have objected to the FDA’s interpretation of Section 505(b)(2). If the FDA’s 
interpretation of Section 505(b)(2) is successfully challenged, the FDA 
may change its 505(b)(2) policies and practices, which could delay or even 
prevent the FDA from approving any NDA that we submit under Section 
505(b)(2). In addition, the pharmaceutical industry is highly competitive, 
and Section 505(b)(2) NDAs are subject to certain requirements designed 
to protect the patent rights of sponsors of previously approved drugs that 
are referenced in a Section 505(b)(2) NDA. These requirements may give 
rise to patent litigation and mandatory delays in approval of our NDAs for 
up to 30 months or longer depending on the outcome of any litigation. It is 
not uncommon for a manufacturer of an approved product to file a citizen 

petition with the FDA seeking to delay approval of, or impose additional 
approval requirements for, pending. competing products. If successful, 
such petitions can significantly delay, or even prevent, the approval of a 
new product. Even if the FDA ultimately denies such a petition, the FDA 
may substantially delay approval while it considers and responds to the 
petition. In addition, even if we are able to utilize the Section 505(b)(2) 
regulatory pathway, there is no guarantee this would ultimately lead to 
streamlined product development or earlier approval.

Interim, “top-line,” and preliminary data from our clinical trials that we 
announce or publish from time to time may change as more patient data 
become available or as additional analyses are conducted, and as the data 
are subject to audit and verification procedures that could result in material 
changes in the final data.

From time to time, we may publish interim, “top-line,” or preliminary 
data from our clinical studies, which is based on a preliminary analysis of 
then-available data, and the results and related findings and conclusions 
are subject to change following a more comprehensive review of the 
data related to the particular study or trial. We also make assumptions, 
estimations, calculations and conclusions as part of our analyses of data, 
and we may not have received or had the opportunity to fully and carefully 
evaluate all data. As a result, the interim, top-line, or preliminary results 
that we report may differ from future results of the same studies or trials, 
or different conclusions or considerations may qualify such results, once 
additional data have been received and fully evaluated. Data from interim 
analyses of clinical trials that we may complete are subject to the risk that 
one or more of the clinical outcomes may materially change as patient 
enrollment continues and more patient data become available. Preliminary 
or “top-line” data also remain subject to audit and verification procedures 
that may result in the final data being materially different from the 
preliminary data we previously published. As a result, interim, “top-line,” 
and preliminary data should be viewed with caution until the final data are 
available. Material adverse changes between preliminary, “top-line,” or 
interim data and final data could significantly harm our business prospects.

Further, others, including regulatory agencies, may not accept or agree 
with our assumptions, estimates, calculations, conclusions or analyses 
or may interpret or weigh the importance of data differently, which 
could impact the value of the particular program, the approvability or 
commercialization of the particular therapeutic candidate or therapeutic 
and our company in general. In addition, the information we choose to 
publicly disclose regarding a particular study or clinical trial is based 
on what is typically extensive information, and you or others may not 
agree with what we determine is the material or otherwise appropriate 
information to include in our disclosure. Any information we determine 
not to disclose may ultimately be deemed significant by you or others with 
respect to future decisions, conclusions, views, activities or otherwise 
regarding a particular therapeutic candidate or our business.

The complexity of a combination therapeutic that includes a drug or 
biologic and a medical device presents additional, unique development 
and regulatory challenges, which may adversely impact our or our Founded 
Entities’ development plans and our or our Founded Entities’ ability to 
obtain regulatory clearance, authorization or approval of our Internal 
Programs or our Founded Entities’ therapeutic candidates.

We or our Founded Entities may decide to pursue marketing authorization 
of a combination therapeutic. A combination therapeutic may include, 
amongst other possibilities, any drug, device, or biologic that is intended 
for use with another individually specified drug, device, or biologic, where 
both are required to achieve the intended use, indication, or effect.

Developing and obtaining regulatory clearance, authorization or approval 
in the United States for combination therapeutics pose unique challenges 
because such therapeutic candidates involve components that are 
regulated by the FDA under different types of regulatory requirements, 
and in the United States by different FDA centers. As a result, such 
therapeutics raise regulatory, policy and review management challenges. 
For example, because divisions from both FDA’s Center for Drug Evaluation 
and Research or Center for Biologics Evaluation and Research and FDA’s 
Center for Devices and Radiological Health must review submissions 
concerning therapeutic candidates that are combination therapeutics 
comprised of drug or biologics and devices, respectively, the regulatory 
review and clearance, authorization or approval process for these 
therapeutics may be more complex than would otherwise be required 
for single-agent therapeutics. In addition, differences in regulatory 
pathways for each component of a combination therapeutic can impact 
the regulatory processes for all aspects of therapeutic development and 
management, including clinical investigation, marketing applications, 
manufacturing and quality control, adverse event reporting, promotion 
and advertising, user fees and post-clearance, authorization or approval 
modifications. Similarly, if applicable, the device components of a 
combination therapeutic candidate will require any necessary clearances, 
certifications or approvals or other marketing authorizations in other 
jurisdictions, which may prove challenging to obtain.

Risk Factor Annex continuedAdditional informationThe EU regulates medical devices and medicinal products separately, 
through different legislative instruments, and the applicable requirements 
will vary depending on the type of drug-device combination product. 
For instance, drug-delivery products intended to administer a medicinal 
product where the medicinal product and the device form a single integral 
product are regulated as medicinal products in the EU. In such a case, 
the marketing authorization application must include – where available 
– the results of the assessment of the conformity of the device part with 
the EU Medical Devices Regulation contained in the manufacturer’s EU 
declaration of conformity of the device or the relevant certificate issued by 
a notified body. If the marketing authorization application does not include 
the results of the conformity assessment and where for the conformity 
assessment of the device, if used separately, the involvement of a notified 
body is required, the EMA or the EU member state competent authority 
must require the applicant to provide a notified body opinion on the 
conformity of the device. By contrast, in case of drug-delivery products 
intended to administer a medicinal product where the device and the 
medicinal product do not form a single integral product (but are e.g., co-
packaged), the medicinal product is regulated in accordance with the rules 
for medicinal products described above while the device part is regulated 
as a medical device and will have to comply with all the requirements set 
forth by the Medical Devices Regulation.

Certain modifications to our Founded Entities’ device therapeutics 
may require new 510(k) clearance or other marketing authorizations or 
certifications and may require our Founded Entities to recall or cease 
marketing their therapeutics.

Akili and Gelesis received de novo classification for EndeavorRx and 
Plenity, respectively, from the FDA. Once a medical device is permitted 
to be legally marketed in the United States pursuant to a 510(k) clearance, 
de novo classification, or a premarket approval, or PMA, a manufacturer 
may be required to notify the FDA of certain modifications to the device. 
Manufacturers determine in the first instance whether a change to a 
medical device requires a new premarket submission, but the FDA 
may review any manufacturer’s decision. The FDA may not agree with 
our Founded Entities’ decisions regarding whether new clearances, 
authorizations or approvals are necessary. They may make modifications 
or add additional features in the future that they believe do not require 
a new 510(k) clearance, de novo marketing authorization, or approval of 
a PMA or PMA amendments or supplements. If the FDA disagrees with 
their determinations and requires them to submit new 510(k) notifications, 
requests for de novo classification, or PMAs (or PMA supplements or 
amendments) for modifications to their previously cleared or authorized 
therapeutics for which they have concluded that new clearances, 
authorization or approvals are unnecessary, they may be required to cease 
marketing or to recall the modified therapeutic until they obtain clearance, 
authorization or approval, and they may be subject to significant regulatory 
fines or penalties.

In the EU, devices lawfully placed on the market pursuant to the EU Medical 
Devices Directive prior to May 26, 2021 may generally continue to be made 
available on the market or put into service, provided that the requirements 
of the transitional provisions are fulfilled. In particular, no substantial 
change must be made to the device as such a modification would 
trigger the obligation to obtain a new certification under the EU Medical 
Devices Regulation and therefore to have a notified body conducting 
a new conformity assessment of the devices. Once our devices will be 
certified under the EU Medical Devices Regulation, we must inform the 
notified body that carried out the conformity assessment of the medical 
devices that we market or sell in the EU and the EEA of any planned 
substantial changes to our quality system or substantial changes to our 
medical devices that could affect compliance with the general safety and 
performance requirements laid down in Annex I to the EU Medical Devices 
Regulation or cause a substantial change to the intended use for which the 
device has been CE marked. The notified body will then assess the planned 
changes and verify whether they affect the products’ ongoing conformity 
with the EU Medical Devices Regulation. If the assessment is favorable, the 
notified body will issue a new certificate of conformity or an addendum to 
the existing certificate attesting compliance with the general safety and 
performance requirements and quality system requirements laid down 
in the Annexes to the EU Medical Devices Regulation. The notified body 
may disagree with our proposed changes and product introductions or 
modifications could be delayed or canceled, which could adversely affect 
our ability to grow our business.

We may not elect or be able to take advantage of any expedited 
development or regulatory review and approval processes available 
to therapeutic candidates granted breakthrough therapy or fast track 
designation by the FDA.

We intend to evaluate and continue ongoing discussions with the FDA 
on regulatory strategies that could enable us or our Founded Entities to 
take advantage of expedited development pathways for certain of our 
Internal Programs or our Founded Entities’ therapeutic candidates in the 
future, although we cannot be certain that our Internal Programs or our 
Founded Entities’ therapeutic candidates will qualify for any expedited 
development pathways or that regulatory authorities will grant, or allow us 
or our Founded Entities to maintain, the relevant qualifying designations. 
Examples of expedited development pathways that we could pursue 
include breakthrough therapy and fast track designation.

The fast track program is intended to expedite or facilitate the process 
for reviewing therapeutic candidates that meet certain criteria. 
Specifically, drugs and biologics are eligible for fast track designation 
if they are intended, alone or in combination with one or more drugs or 
biologics, to treat serious or life-threatening diseases or conditions and 
demonstrate the potential to address unmet medical needs for such 
diseases or conditions. Fast track designation applies to the combination 
of the therapeutic candidate and the specific indication for which it is 
being studied. The sponsor of a fast track therapeutic candidate has 
opportunities for more frequent interactions with the applicable FDA 
review team during product development and, once a BLA or NDA is 
submitted, the application may be eligible for priority review. An NDA 
or BLA submitted for a Fast Track therapeutic candidate may also be 
eligible for rolling review, where the FDA may consider for review sections 
of the NDA or BLA on a rolling basis before the complete application 
is submitted, if the sponsor provides a schedule for the submission of 
the sections of the NDA or BLA, the FDA agrees to accept sections of 
the application and determines that the schedule is acceptable, and the 
sponsor pays any required user fees upon submission of the first section of 
the application.

A “breakthrough therapy” is defined as a drug or biologic that is intended, 
alone or in combination with one or more other drugs or biologics, to treat 
a serious or life-threatening disease or condition, where preliminary clinical 
evidence indicates that the drug or biologic may demonstrate substantial 
improvement over existing therapies on one or more clinically significant 
endpoints, such as substantial treatment effects observed early in clinical 
development. For therapeutic candidates that have been designated 
as breakthrough therapies, increased interaction and communication 
between the FDA and the sponsor of the trial can help to identify the 
most efficient path for clinical development while minimizing the number 
of patients placed in ineffective control regimens. Drugs and biologics 
designated as breakthrough therapies also receive the same benefits 
associated with fast track designation, including eligibility for rolling review 
of a submitted NDA or BLA, if the relevant criteria are met.

Even if we believe a particular therapeutic candidate is eligible for 
breakthrough therapy or fast track designation, we cannot assure you 
that the FDA would decide to grant it. Breakthrough therapy designation 
and fast track designation do not change the standards for approval, 
and there is no assurance that such designation or eligibility will result in 
expedited review or approval. Thus, even if we or our Founded Entities do 
receive breakthrough therapy, fast track designation, or other comparable 
designation, we or our Founded Entities may not experience a faster 
development process, review or approval compared to conventional 
FDA procedures. In addition, the FDA may withdraw either breakthrough 
therapy or fast track designation if it believes that the therapeutic no 
longer meets the qualifying criteria. Our business may be harmed if we are 
unable to avail ourselves of these or any other expedited development and 
regulatory pathways.

We may not be able to obtain or maintain orphan drug designation or 
exclusivity for our therapeutic candidates.

Regulatory authorities in some jurisdictions, including the United States, 
may designate drugs for relatively small patient populations as orphan 
drugs. Under the Orphan Drug Act, the FDA may designate a drug as 
an orphan drug if it is intended to treat a rare disease or condition, 
which is generally defined as a patient population of fewer than 200,000 
individuals in the United States, or if the disease or condition affects more 
than 200,000 individuals in the United States and there is no reasonable 
expectation that the cost of developing the drug for the type of disease or 
condition will be recovered from sales of the product in the United States. 
The criteria for designating an “orphan medicinal product” in the EU are 
similar in principle to those in the United States. A medicinal product can 
be designated as an orphan if its sponsor can establish that: (1) the product 
is intended for the diagnosis, prevention or treatment of a life threatening 
or chronically debilitating condition (2) either (a) such condition affects not 
more than five in 10,000 persons in the EU when the application is made, or 
(b) the product, without the benefits derived from the orphan status, would 

Risk Factor Annex continuedAdditional information196    PureTech Health plc   Annual Report and Accounts 2023

not generate sufficient return in the EU to justify the necessary investment; 
and (3) there exists no satisfactory method of diagnosis, prevention 
or treatment of the condition in question that has been authorized for 
marketing in the EU or, if such method exists, the product will be of 
significant benefit to those affected by that condition.

Orphan drug designation entitles a party to financial incentives, such as tax 
advantages and user fee waivers. Additionally, if a product that has orphan 
designation subsequently receives the first FDA approval for the disease 
or condition for which it has such designation, the product is entitled 
to orphan drug exclusivity, which means that the FDA may not approve 
any other applications to market the same drug for the same disease 
or condition for seven years, except in certain circumstances, such as a 
showing of clinical superiority (i.e., another product is safer, more effective 
or makes a major contribution to patient care) over the product with 
orphan exclusivity or where the manufacturer is unable to assure sufficient 
product quantity. Competitors, however, may receive approval of different 
products for the same disease or condition for which the orphan product 
has exclusivity, or obtain approval for the same product but for a different 
disease or condition than that for which the orphan product has exclusivity. 
In the EU, orphan designation must be requested before submitting an 
MAA. An EU orphan designation entitles a party to incentives such as 
reduction of fees or fee waivers, protocol assistance, and access to the 
centralized procedure. Upon grant of a marketing authorization, orphan 
medicinal products are entitled to ten years of market exclusivity for the 
approved indication, which means that the competent authorities cannot 
accept another MAA, or grant a marketing authorization, or accept an 
application to extend a marketing authorization for a similar medicinal 
product for the same indication for a period of ten years. The period of 
market exclusivity is extended by two years for orphan medicinal products 
that have also complied with an agreed pediatric investigation plan, or PIP. 
No extension to any supplementary protection certificate can be granted 
on the basis of pediatric studies for orphan indications.

We have obtained orphan drug designation in the United States for LYT-
200 for the treatment of pancreatic cancer and for the treatment of acute 
myeloid leukemia, and we may also seek orphan drug designation for other 
of our therapeutic candidates in the future. We may not be the first to 
obtain regulatory approval of any therapeutic candidate for its orphan-
designated disease or condition and may therefore not obtain orphan 
drug exclusivity. In addition, exclusive marketing rights in the United States 
may be limited if we seek approval for an disease or condition broader 
than the orphan-designated disease or condition or may be lost if the FDA 
later determines that the request for orphan designation was materially 
defective or if the manufacturer is unable to assure sufficient quantities 
of the product to meet the needs of patients with the rare disease or 
condition. In the EU, the orphan exclusivity period may be reduced to six 
years if, at the end of the fifth year, it is established that the product no 
longer meets the criteria for which it received orphan drug destination, 
including where it is shown that the product is sufficiently profitable not to 
justify maintenance of market exclusivity or where the prevalence of the 
condition has increased above the threshold. Additionally, a marketing 
authorization may be granted to a similar product for the same indication 
at any time if (i) the second applicant can establish that its product, 
although similar, is safer, more effective or otherwise clinically superior; (ii) 
the applicant consents to a second orphan medicinal product application; 
or (iii) the applicant cannot supply enough orphan medicinal product.

Orphan drug designation does not ensure that we will receive marketing 
exclusivity in a particular market, and we cannot assure you that any 
future application for orphan drug designation with respect to any other 
therapeutic candidate will be granted. Orphan drug designation neither 
shortens the development time or regulatory review time of a drug, nor 
gives the drug any advantage in the regulatory review or approval process.

If we or our Founded Entities are unable to successfully validate, develop 
and obtain regulatory clearance, certification, authorization or approval 
for companion diagnostic tests for any future drug candidates that require 
or would commercially benefit from such tests, or experience significant 
delays in doing so, we or our Founded Entities may not realize the full 
commercial potential of these drug candidates.

In connection with the clinical development of the therapeutic candidates 
within our Internal Programs or Founded Entities’ therapeutic candidates 
for certain indications, we or our Founded Entities may work with 
collaborators to develop or obtain access to in vitro companion diagnostic 
tests to identify patient subsets within a disease category who may 
derive selective and meaningful benefit from our drug candidates. To 
be successful, we, our Founded Entities or our collaborators will need 
to address a number of scientific, technical, regulatory and logistical 
challenges. The FDA and comparable foreign regulatory authorities 
regulate in vitro companion diagnostics as medical devices and, under 
that regulatory framework, will likely require the conduct of clinical trials 
to demonstrate the safety and effectiveness of any diagnostics we or our 

Founded Entities may develop, which we expect will require separate 
regulatory clearance, certification, authorization or approval prior to 
commercialization. In addition, if safe and effective use of a therapeutic 
product depends on an in vitro companion diagnostic, the FDA generally 
will require approval, authorization or clearance of that diagnostic, known 
as a companion diagnostic, before or at the same time that the FDA 
approves the therapeutic product.

In addition, the FDA has historically required approval of a PMA application 
for companion diagnostics associated with cancer medications. However, 
in January 2024, the FDA announced its intention to initiate the process 
to reclassify into Class II most in vitro diagnostic tests that are currently 
regulated as Class III medical devices, including certain companion 
diagnostic in-vitro diagnostics. If such reclassification efforts occur, any 
companion diagnostics that are the subject of the down-classification 
may no longer require approval of a PMA application, but rather may be 
marketed pursuant to the generally less burdensome 510(k) clearance 
process. However, there is no assurance that any companion diagnostic 
required for therapeutic candidates within our Internal Programs or those 
of our Founded Entities will benefit from the reclassification, or that the 
reclassification, even if it does occur, will result in a shorter timeline to 
development or marketing of the companion diagnostic.

We or our Founded Entities may rely on third parties for the design, 
development and manufacture of companion diagnostic tests for our 
Internal Programs’ or our Founded Entities’ therapeutic candidates 
that may require such tests. If we or our Founded Entities enter into 
such collaborative agreements, we will be dependent on the sustained 
cooperation and effort of our future collaborators in developing and 
obtaining approval for these companion diagnostics. It may be necessary 
to resolve issues such as selectivity/specificity, analytical validation, 
reproducibility, or clinical validation of companion diagnostics during 
the development and regulatory clearance, certification, authorization 
or approval processes. Moreover, even if data from preclinical studies 
and early clinical trials appear to support development of a companion 
diagnostic for a therapeutic candidate, data generated in later clinical trials 
may fail to support the analytical and clinical validation of the companion 
diagnostic. We, our Founded Entities and our future collaborators may 
encounter difficulties in developing, obtaining regulatory clearance, 
certification, authorization or approval for, manufacturing and 
commercializing companion diagnostics similar to those we face with 
respect to the therapeutic candidates within our Internal Programs 
themselves, including issues with achieving regulatory clearance, 
certification, authorization or approval, production of sufficient quantities 
at commercial scale and with appropriate quality standards, and in gaining 
market acceptance. If we or our Founded Entities are unable to successfully 
develop companion diagnostics for these therapeutic candidates, or 
experience delays in doing so, the development of these therapeutic 
candidates may be adversely affected, these therapeutic candidates may 
not obtain marketing approval, and we may not realize the full commercial 
potential of any of these therapeutic candidates that obtain marketing 
approval. As a result, our business, results of operations and financial 
condition could be materially harmed. In addition, a diagnostic company 
with whom we or our Founded Entities contract may decide to discontinue 
selling or manufacturing the companion diagnostic test that we anticipate 
using in connection with development and commercialization of our 
Internal Programs or our Founded Entities’ therapeutic candidates or our 
relationship with such diagnostic company may otherwise terminate. We 
or our Founded Entities may not be able to enter into arrangements with 
another diagnostic company to obtain supplies of an alternative diagnostic 
test for use in connection with the development and commercialization 
of our Internal Programs or our Founded Entities’ therapeutic candidates 
or do so on commercially reasonable terms, which could adversely affect 
and/or delay the development or commercialization of our or our Founded 
Entities’ therapeutic candidates.

For any cleared, certified, authorized or approved therapeutic, we or our 
Founded Entities will be subject to ongoing regulatory obligations and 
continued regulatory review, which may result in significant additional 
expense and we or our Founded Entities may be subject to penalties if 
we or our Founded Entities fail to comply with regulatory requirements or 
experience unanticipated problems with the therapeutic candidates within 
our Internal Programs or our Founded Entities’ therapeutic candidates.

Gelesis’ Plenity and Akili’s EndeavorRx are, and any of the therapeutic 
candidates within our Internal Programs or our Founded Entities’ 
therapeutic candidates that are cleared, certified, authorized or approved 
will be, subject to ongoing regulatory requirements for manufacturing, 
labeling, packaging, storage, advertising, promotion, sampling, record-
keeping, conduct of post-marketing studies, and submission of safety, 
efficacy and other post-market information, including both federal and 
state requirements in the United States and requirements of comparable 
foreign regulatory authorities.

Risk Factor Annex continuedAdditional informationPureTech Health plc   Annual Report and Accounts 2023    197  

Manufacturers and manufacturers’ facilities are required to comply 
with extensive requirements imposed by the FDA, the EMA and other 
comparable foreign regulatory authorities, including ensuring that 
quality control and manufacturing procedures conform to current good 
manufacturing practices, or cGMP, or similar foreign regulations. As 
such, we and our CMOs are subject to continual review and inspections 
to assess compliance with cGMP, or similar foreign requirements and 
adherence to commitments made in any marketing authorization, and 
any future 510(k), de novo classification, certification, PMA, NDA, BLA or 
marketing authorization application, or MAA, or equivalent application. 
We and our CMOs are also subject to requirements pertaining to the 
registration of our manufacturing facilities and the listing of our and our 
Founded Entities’ therapeutics and therapeutic candidates with the FDA; 
continued complaint, adverse event and malfunction reporting; corrections 
and removals reporting; and labeling and promotional requirements. 
Accordingly, we and others with whom we work must continue to expend 
time, money, and effort in all areas of regulatory compliance, including 
manufacturing, production and quality control. Gelesis’ and Akili’s 
marketing authorizations and certifications for Plenity and EndeavorRx, 
respectively, are and any regulatory clearances, certification, authorization 
or approvals that we may receive for the therapeutic candidates within our 
Internal Programs or our Founded Entities’ therapeutic candidates will be, 
subject to limitations on the cleared, certified, authorized or approved 
indicated uses for which the therapeutic may be marketed and promoted 
or to the conditions of approval. Any regulatory clearances, certifications, 
authorizations or approvals that we may receive for the therapeutic 
candidates within our Internal Programs may contain requirements for 
potentially costly post-marketing testing, such as Phase 4 clinical trials and 
surveillance to monitor the safety and efficacy of a drug therapeutic. We 
are required to report certain adverse reactions and production problems, 
if any, to the FDA and other comparable foreign regulatory authorities. 
Any new legislation addressing drug or medical safety issues could result 
in delays in therapeutic development or commercialization, or increased 
costs to assure compliance.

The FDA and other agencies, including the U.S. Department of Justice, 
and for certain therapeutics, the Federal Trade Commission, closely 
regulate and monitor the marketing, labeling, advertising and promotion 
of therapeutics to ensure that they are manufactured, marketed and 
distributed only for the cleared, certified, authorized or approved 
indications and in accordance with the provisions of the cleared, certified, 
authorized or approved labeling. We are, and will be, required to 
comply with requirements concerning advertising and promotion for the 
therapeutic candidates within our Internal Programs, if cleared, certified, 
authorized or approved. For example, promotional communications 
with respect to prescription drugs and medical devices are subject to a 
variety of legal and regulatory restrictions and must be consistent with the 
information in the therapeutic’s label or labeling. We may not promote our 
therapeutics for indications or uses for which they do not have approval, 
certification, authorization or clearance.

The holder of a cleared 510(k), de novo classification, certification or an 
approved NDA, BLA, PMA, MAA or equivalent marketing authorization 
must submit new or supplemental applications and obtain clearance, 
authorization or approval for certain changes to the approved therapeutic, 
therapeutic labeling, or manufacturing process. For example, any 
modification to Plenity or EndeavorRx that could significantly affect its 
safety or effectiveness or that would constitute a major change in its 
intended use could require a new 510(k) clearance, de novo classification, 
certification or approval of PMA application. Delays in obtaining required 
clearances, certifications or approvals would harm our ability to introduce 
new or enhanced therapeutic in a timely manner, which in turn would harm 
our or our Founded Entities’ future growth. Failure to submit a new or 
supplemental application and to obtain approval or certification for certain 
changes prior to marketing the modified therapeutic may require a recall 
or to stop selling or distributing the marketed therapeutic as modified, and 
may lead to significant enforcement actions.

Subject to the transitional provisions and in order to sell our products 
in EU member states, our products must comply with the general safety 
and performance requirements set forth in the new EU Medical Device 
Regulation (EU) 2017/745, which repeals and replaces the EU Medical 
Devices Directive. Compliance with these requirements is a prerequisite to 
be able to affix the European Conformity, or “CE”, mark to our products, 
without which they cannot be marketed or sold in the EU. All medical 
devices placed on the market in the EU must meet the general safety 
and performance requirements laid down in Annex I to the EU Medical 
Devices Regulation (EU) 2017/745 including the requirement that a 
medical device must be designed and manufactured in such a way that, 
during normal conditions of use, it is suitable for its intended purpose. 
Medical devices must be safe and effective and must not compromise 
the clinical condition or safety of patients, or the safety and health of 
users and – where applicable – other persons, provided that any risks 
which may be associated with their use constitute acceptable risks when 
weighed against the benefits to the patient and are compatible with 

a high level of protection of health and safety, taking into account the 
generally acknowledged state of the art. To demonstrate compliance with 
the general safety and performance requirements, we or our Founded 
Entities must undergo a conformity assessment procedure, which varies 
according to the type of medical device and its (risk) classification. 
Except for low risk medical devices (Class I), where the manufacturer can 
self-assess the conformity of its products with the general safety and 
performance requirements (except for any parts which relate to sterility, 
metrology or reuse aspects), a conformity assessment procedure requires 
the intervention of a notified body. The notified body would typically audit 
and examine the technical file and the quality system for the manufacture, 
design and final inspection of our devices. If satisfied that the relevant 
product conforms to the relevant general safety and performance 
requirements, the notified body issues a certificate of conformity, which 
the manufacturer uses as a basis for its own declaration of conformity. 
The manufacturer may then apply the CE mark to the device, which allows 
the device to be placed on the market throughout the EU. If we fail to 
comply with applicable laws and regulations, we would be unable to affix 
the CE mark to our products, which would prevent us from selling them 
within the EU. In June 2020, Gelesis received a certification for Plenity as a 
class III medical device indicated for weight loss in overweight and obese 
adults with a Body Mass Index of 25-40 kg/m2, when used in conjunction 
with diet and exercise. Also in June 2020, Akili received a certification for 
EndeavorRx as a prescription-only digital therapeutic software intended 
for the treatment of attention and inhibitory control deficits in paediatric 
patients with ADHD.

We or our Founded Entities could also be required to conduct post-
marketing clinical trials to verify the safety and efficacy of our or our 
Founded Entities’ therapeutics in general or in specific patient subsets. 
If original marketing approval of a drug or biologic was obtained via 
an accelerated approval pathway, we or our Founded Entities could 
be required to conduct a successful post-marketing clinical trial to 
confirm clinical benefit for our or our Founded Entities’ therapeutics. 
An unsuccessful post-marketing study or failure to complete such a 
study could result in the withdrawal of marketing clearance, certification, 
authorization or approval.

If a regulatory agency discovers previously unknown problems with 
a therapeutic, such as AEs of unanticipated severity or frequency, or 
problems with the facility where the therapeutic is manufactured, or 
disagrees with the promotion, marketing or labeling of a therapeutic, 
such regulatory agency may impose restrictions on that therapeutic or 
us, including requiring withdrawal of the therapeutic from the market. 
If we or our Founded Entities fail to comply with applicable regulatory 
requirements, a regulatory agency or enforcement authority may, 
among other things:

 — issue warning letters that would result in adverse publicity;

 — impose civil or criminal penalties;

 — suspend or withdraw regulatory approvals or certifications;

 — suspend any of our or our Founded Entities’ ongoing clinical trials;

 — refuse to approve pending applications or supplements to approved 

applications submitted by us or our Founded Entities;

 — impose restrictions on our operations, including closing our 

CMOs’ facilities;

 — seize or detain therapeutics; or

 — require a recall.

Any government investigation of alleged violations of law could require 
us to expend significant time and resources in response, and could 
generate negative publicity. Any failure to comply with ongoing regulatory 
requirements may significantly and adversely affect our ability to 
commercialize and generate revenue from our therapeutics. If regulatory 
sanctions are applied or if regulatory clearance, authorization or approval 
is withdrawn, the value of our company and our operating results will be 
adversely affected.

The FDA’s and other regulatory authorities’ policies may change and 
additional government regulations may be enacted that could prevent, 
limit or delay regulatory clearance, certification, authorization or approval 
of the therapeutic candidates within our Internal Program or our Founded 
Entities’ therapeutic candidates. 

In addition, the FDA has historically required approval of a PMA application 
for companion diagnostics associated with cancer medications. However, 
in January 2024, the FDA announced its intention to initiate the process 
to reclassify into Class II most in vitro diagnostic tests that are currently 
regulated as Class III medical devices, including certain companion 
diagnostic in-vitro diagnostics. If such reclassification efforts occur, any 
companion diagnostics that are the subject of the down-classification 
may no longer require approval of a PMA application, but rather may be 
marketed pursuant to the generally less burdensome 510(k) clearance 
process. However, there is no assurance that any companion diagnostic 
required for therapeutic candidates within our Internal Programs or those 

Risk Factor Annex continuedAdditional information198    PureTech Health plc   Annual Report and Accounts 2023

of our Founded Entities will benefit from the reclassification, or that the 
reclassification, even if it does occur, will result in a shorter timeline to 
development or marketing of the companion diagnostic.

We also cannot predict the likelihood, nature or extent of government 
regulation that may arise from future legislation or administrative action, 
either in the United States or abroad. If these legislative or administrative 
actions impose constraints on the FDA’s ability to engage in oversight 
and implementation activities in the normal course, our business may be 
negatively impacted. Outside of the United States, for instance, the EU 
pharmaceutical legislation is currently undergoing a complete review 
process, in the context of the Pharmaceutical Strategy for Europe initiative, 
launched by the European Commission in November 2020. The European 
Commission’s proposal for revision of several legislative instruments 
related to medicinal products (potentially reducing the duration of 
regulatory data protection, revising the eligibility for expedited pathways, 
etc.) was published on April 26, 2023. The proposed revisions, remain 
to be agreed and adopted by the European Parliament and European 
Council, and the proposals may therefore be substantially revised before 
adoption, which is not anticipated before early 2026. The revisions may, 
however, have a significant impact on the biopharmaceutical industry in 
the long term.

The FDA and other regulatory agencies actively enforce the laws and 
regulations prohibiting the promotion of off-label uses.

If, for any of our Internal Programs that are cleared or approved, we are 
found to have improperly promoted off-label uses of those therapeutics, 
we may become subject to significant liability. The FDA and other 
regulatory agencies strictly regulate the promotional claims that may be 
made about prescription therapeutics, if cleared, authorized or approved. 
In particular, while the FDA permits the dissemination of truthful and 
non-misleading information about a cleared, authorized or approved 
therapeutic, a manufacturer may not promote a therapeutic for uses 
that are not cleared, authorized or approved by the FDA or such other 
regulatory agencies as reflected in the therapeutic’s cleared, authorized or 
approved labeling. If we are found to have promoted such off-label uses, 
we may become subject to significant liability. The federal government 
has levied large civil and criminal fines against companies for alleged 
improper promotion of off-label use and has enjoined several companies 
from engaging in off-label promotion. The FDA has also requested that 
companies enter into consent decrees, corporate integrity agreements 
or permanent injunctions under which specified promotional conduct 
must be changed or curtailed. If we cannot successfully manage the 
promotion of the therapeutic candidates within our Internal Programs, if 
cleared, authorized or approved, we could become subject to significant 
liability, which would materially adversely affect our business and 
financial condition.

Certain of our therapeutic candidates may be regulated as controlled 
substances, the making, use, sale, importation, exportation, and 
distribution of which are subject to significant regulation by the U.S. Drug 
Enforcement Administration, or DEA, and other regulatory agencies.

We expect that certain of our therapeutic candidates, if approved, will be 
regulated as controlled substances, which are subject to state, federal, 
and foreign laws and regulations regarding their manufacture, use, sale, 
importation, exportation, and distribution. Among other things, controlled 
substances are regulated under the federal Controlled Substances Act of 
1970, or CSA, and regulations of the DEA. 

The DEA regulates controlled substances as Schedule I, II, III, IV or V 
substances. Schedule I substances by definition have no established 
medicinal use and may not be marketed or sold in the United States. 
A pharmaceutical product may be listed as Schedule II, III, IV or V, with 
Schedule II substances considered to present the highest risk of abuse 
and Schedule V substances the lowest relative risk of abuse among 
such substances. Certain of our other therapeutic candidates contain 
Schedule IV substances, which subjects such therapeutic candidates to 
additional restrictions regarding their manufacture, shipment, storage, 
sale and use, depending on the scheduling of the active ingredients, 
and may limit the commercial potential of any of our therapeutic 
candidates, if approved.

Various states also independently regulate controlled substances. Though 
state controlled substances laws often mirror federal law, because the 
states are separate jurisdictions, they may separately schedule drugs as 
well. While some states automatically schedule a drug when the DEA 
does so, in other states there must be rulemaking or a legislative action. 
State scheduling may delay commercial sale of any controlled substance 
drug product for which we obtain federal regulatory approval and adverse 
scheduling could impair the commercial attractiveness of such product. 
We or our collaborators must also obtain separate state registrations in 
order to be able to obtain, handle and distribute controlled substances for 
clinical trials or commercial sale, and failure to meet applicable regulatory 
requirements could lead to enforcement and sanctions from the states in 
addition to those from the DEA or otherwise arising under federal law.

For any of our products or therapeutic candidates classified as controlled 
substances, we and our suppliers, manufacturers, contractors, customers 
and distributors are required to obtain and maintain applicable 
registrations from state, federal and foreign law enforcement and 
regulatory agencies and comply with state, federal and foreign laws and 
regulations regarding the manufacture, use, sale, importation, exportation 
and distribution of controlled substances. There is a risk that DEA 
regulations may limit the supply of the compounds used in clinical trials 
for our therapeutic candidates, and, in the future, the ability to produce 
and distribute our products in the volume needed to meet commercial 
demand. Regulations associated with controlled substances govern 
manufacturing, labeling, packaging, testing, dispensing, production 
and procurement quotas, recordkeeping, reporting, handling, shipment 
and disposal. These regulations increase the personnel needs and 
the expense associated with development and commercialization of 
therapeutic candidates including controlled substances. The DEA, and 
some states, conduct periodic inspections of registered establishments 
that handle controlled substances. Failure to obtain and maintain 
required registrations or comply with any applicable regulations 
could delay or preclude us from developing and commercializing our 
therapeutic candidates containing controlled substances and subject 
us to enforcement action. The DEA may seek civil penalties, refuse to 
renew necessary registrations or initiate proceedings to revoke those 
registrations. In some circumstances, violations could lead to criminal 
proceedings. Because of their restrictive nature, these regulations could 
limit commercialization of any of our products or therapeutic candidates 
that are classified as controlled substances.

The EU legislation does not establish different classes of narcotic 
or psychotropic substances. However, the United Nations, or UN, 
Single Convention on Narcotic Drugs of 1961 and the UN Convention 
on Psychotropic Substances of 1971, or the UN Conventions, codify 
internationally applicable control measures to ensure the availability of 
narcotic drugs and psychotropic substances for medical and scientific 
purposes. The individual EU member states are all signatories to these UN 
Conventions. All signatories have a dual obligation to ensure that these 
substances are available for medical purposes and to protect populations 
against abuse and dependence. The UN Conventions regulate narcotic 
drugs and psychotropic substances as Schedule I, II, III, IV substances with 
Schedule II substances presenting the lowest relative risk of abuse among 
such substances and Schedule I and IV substances considered to present 
the highest risk of abuse.

The UN Conventions require signatories to require all persons 
manufacturing, trading (including exporting and importing) or distributing 
controlled substances to obtain a license from the relevant authority. Each 
individual export or import of a controlled substance must also be subject 
to an authorization. The obligations provided in the UN Conventions 
and additional requirements are implemented at national level and 
requirements may vary from one member state to another. In order to 
develop and commercialize our products in the EU, we need to comply with 
the national requirements related to controlled substances which is costly 
and may affect our development plans in the EU.

Risks Related to Manufacturing our Therapeutic Candidates or Those 
of our Founded Entities

Certain of the therapeutic candidates being developed by us or our 
Founded Entities are novel, complex and difficult to manufacture. 
We could experience manufacturing problems that result in delays 
in our development or commercialization programs or otherwise 
harm our business.

The manufacturing processes our CMOs use to produce our and our 
Founded Entities’ therapeutic candidates are complex and in certain 
cases novel. Several factors could cause production interruptions, 
including inability to develop novel manufacturing processes, equipment 
malfunctions, facility contamination, raw material shortages or 
contamination, natural disasters, disruption in utility services, human error 
or disruptions in the operations of our suppliers, including acquisition of 
the supplier by a third party or declaration of bankruptcy. For example, 
Vedanta has its own proprietary cGMP manufacturing facilities for 
certain therapeutic candidates, including VE202, VE303, VE800 and 
VE416. Creating defined consortia of live microbial therapeutics for 
these therapeutic candidates is inherently complex, and therefore can 
be vulnerable to delays. The expertise required to manufacture these 
therapeutic candidates is unique to Vedanta, and as a result, it would 
be difficult and time consuming to find an alternative CMO. In addition, 
manufacturing of clinical supply for certain of our therapeutic candidates 
is dependent on third party CMOs, and manufacturing such therapeutic 
candidates is inherently complex. 

Risk Factor Annex continuedAdditional informationPureTech Health plc   Annual Report and Accounts 2023    199  

Some of our and our Founded Entities’ therapeutic candidates include 
biologics, some of which have physical and chemical properties that cannot 
be fully characterized. As a result, assays of the finished product may not 
be sufficient to ensure that the therapeutic candidate is consistent from 
lot-to-lot or will perform in the intended manner. Accordingly, our CMOs 
must employ multiple steps to control the manufacturing process to assure 
that the process is reproducible and the therapeutic candidate is made 
strictly and consistently in compliance with the process. Problems with the 
manufacturing process, even minor deviations from the normal process, 
could result in therapeutic defects or manufacturing failures that result 
in lot failures, therapeutic recalls, product liability claims or insufficient 
inventory to conduct clinical trials or supply commercial markets. We or our 
Founded Entities may encounter problems achieving adequate quantities 
and quality of clinical-grade materials that meet the FDA, the EMA or other 
applicable standards or specifications with consistent and acceptable 
production yields and costs.

In addition, the FDA and other foreign regulatory authorities may require 
us or our Founded Entities to submit samples of any lot of any approved 
therapeutic together with the protocols showing the results of applicable 
tests at any time. Under some circumstances, the FDA or other foreign 
regulatory authorities may require that we or our Founded Entities not 
distribute a lot until the agency authorizes its release. Slight deviations in 
the manufacturing process, including those affecting quality attributes and 
stability, may result in unacceptable changes in the therapeutic that could 
result in lot failures or therapeutic recalls. Lot failures or therapeutic recalls 
could cause us or our Founded Entities to delay therapeutic launches or 
clinical trials, which could be costly to us and otherwise harm our business, 
financial condition, results of operations and prospects.

Our CMOs also may encounter problems hiring and retaining 
the experienced scientific, quality assurance, quality-control and 
manufacturing personnel needed to operate our manufacturing processes, 
which could result in delays in production or difficulties in maintaining 
compliance with applicable regulatory requirements.

Any problems in our CMOs’ manufacturing process or facilities could result 
in delays in planned clinical trials and increased costs, and could make 
us a less attractive collaborator for potential partners, including larger 
biotechnology companies and academic research institutions, which could 
limit access to additional attractive development programs. Problems 
in our manufacturing process could restrict our ability to meet potential 
future market demand for therapeutics.

We do not currently have nor do we plan to acquire the infrastructure or 
capability internally to manufacture our clinical drug supplies for use in the 
conduct of our clinical trials, and we lack the resources and the capability 
to manufacture the therapeutic candidates within our Internal Programs 
on a clinical or commercial scale. Instead, we rely on our third-party 
manufacturing partners for the production of the active pharmaceutical 
ingredient, or API, and drug formulation. The facilities used by our third-
party manufacturers to manufacture our therapeutic candidates that we 
may develop must be successfully inspected by the applicable regulatory 
authorities, including the FDA, after we submit any NDA or BLA to the FDA.

We are currently completely dependent on our third-party manufacturers 
for the production of certain of our therapeutic candidates in accordance 
with cGMPs or similar foreign requirements, which include, among other 
things, quality control, quality assurance and the maintenance of records 
and documentation.

Although we have entered into agreements for the manufacture of clinical 
supplies for such therapeutic candidates, our third-party manufacturers 
may not perform as agreed, may be unable to comply with these cGMP or 
similar foreign requirements and with FDA, state and foreign regulatory 
requirements or may terminate its agreement with us. If any of our 
third-party manufacturers cannot successfully manufacture material that 
conforms to our specifications and the applicable regulatory authorities’ 
strict regulatory requirements, pass regulatory inspection or maintain a 
compliance status acceptable to the FDA or state or foreign regulatory 
authorities, our NDAs, BLAs or MAAs will not be approved. In addition, 
although we are ultimately responsible for ensuring therapeutic quality, 
we have no direct day-to-day control over our third-party manufacturers’ 
ability to maintain adequate quality control, quality assurance and 
qualified personnel. If our third-party manufacturers are unable to satisfy 
the regulatory requirements for the manufacture of our therapeutics, if 
approved, or if our suppliers or third-party manufacturers decide they 
no longer want to manufacture our therapeutics, we will need to find 
alternative manufacturing facilities, which would be time-consuming and 
significantly impact our ability to develop, obtain regulatory approval 
for or market our therapeutics, if approved. If we are required to change 
contract manufacturers for any reason, we will be required to show that 
the new manufacturer maintains facilities and procedures that comply 
with quality standards and with all applicable regulations. We will also 
need to verify, such as through a manufacturing comparability study, 
that any new manufacturing process or procedure will produce our 

therapeutic candidate according to specifications previously submitted to 
the FDA or another regulatory authority. We might be unable to identify 
manufacturers for long-term clinical and commercial supply on acceptable 
terms or at all. Manufacturers are subject to ongoing periodic announced 
and unannounced inspection by the FDA and other governmental 
authorities to ensure compliance with government regulations. As a result, 
our third-party manufacturers may be subject to increased scrutiny.

If we were to experience an unexpected loss of supply for clinical 
development or commercialization, we could experience delays in our 
ongoing or planned clinical trials as our third-party manufacturers would 
need to manufacture additional quantities of our clinical and commercial 
supply and we may not be able to provide sufficient lead time to enable 
our third-party manufacturers to schedule a manufacturing slot, or to 
produce the necessary replacement quantities. This could result in delays 
in progressing our clinical development activities and achieving regulatory 
approval for our therapeutics, which could materially harm our business.

The manufacture of pharmaceutical therapeutics is complex and requires 
significant expertise and capital investment, including the development 
of advanced manufacturing techniques and process controls. We and 
our contract manufacturers must comply with cGMP or similar foreign 
regulations and guidelines. Manufacturers of pharmaceutical therapeutics 
often encounter difficulties in production, particularly in scaling up and 
validating initial production. These problems include difficulties with 
production costs and yields, quality control, including stability of the 
product, quality assurance testing, operator error, shortages of qualified 
personnel, as well as compliance with strictly enforced federal, state and 
foreign regulations. Furthermore, if microbial, viral or other contaminations 
are discovered in our therapeutics or in the manufacturing facilities in 
which our therapeutic candidate are made, such manufacturing facilities 
may need to be closed for an extended period of time to investigate and 
remedy the contamination. We cannot assure you that any stability or other 
issues relating to the manufacture of any of our therapeutic candidates will 
not occur in the future. Additionally, our manufacturers may experience 
manufacturing difficulties due to resource constraints or as a result of labor 
disputes or unstable political environments. If our manufacturers were to 
encounter any of these difficulties, or otherwise fail to comply with their 
contractual obligations, our ability to provide any therapeutic candidates 
to patients in clinical trials would be jeopardized. Any delay or interruption 
in the supply of clinical trial supplies could delay the completion of clinical 
trials, increase the costs associated with maintaining clinical trial programs 
and, depending upon the period of delay, require us to commence new 
clinical trials at additional expense or terminate clinical trials completely.

Any adverse developments affecting clinical or potential commercial 
manufacturing of our therapeutic candidates may result in shipment 
delays, inventory shortages, lot failures, therapeutic withdrawals or recalls, 
or other interruptions in the supply of our therapeutic candidates. We may 
also have to take inventory write-offs and incur other charges and expenses 
for therapeutic candidates that fail to meet specifications, undertake 
costly remediation efforts or seek more costly manufacturing alternatives. 
Accordingly, failures or difficulties faced at any level of our supply chain 
could materially adversely affect our business and delay or impede the 
development and commercialization of any of our therapeutic candidates 
and could have a material adverse effect on our business, prospects, 
financial condition and results of operations.

Our or our Founded Entities’ therapeutic candidates must be manufactured 
in accordance with federal, state and international regulations, and we or 
our Founded Entities could be forced to recall our or our Founded Entities’ 
medical devices and therapeutic candidates or terminate production if we 
or our Founded Entities fail to comply with these regulations.

The methods used in, and the facilities used for, the manufacture of 
medical device therapeutics and therapeutic candidates of our Founded 
Entities, including Gelesis, Akili, Follica and Sonde, must comply with the 
FDA’s cGMPs for medical devices, known as the QSR, which is a complex 
regulatory scheme that covers the procedures and documentation of, 
among other requirements, the design, testing, validation, verification, 
complaint handling, production, process controls, quality assurance, 
labeling, supplier evaluation, packaging, handling, storage, distribution, 
installation, servicing and shipping of medical devices. Furthermore, 
we and our Founded Entities are required to verify that our suppliers 
maintain facilities, procedures and operations that comply with our quality 
standards and applicable regulatory requirements. The FDA enforces the 
QSR through, among other oversight methods, periodic announced or 
unannounced inspections of medical device manufacturing facilities, which 
may include the facilities of subcontractors, suppliers or CMOs. Our and 
our Founded Entities’ therapeutics and therapeutic candidates are also 
subject to similar state regulations and various laws and regulations of 
foreign countries governing manufacturing.

Risk Factor Annex continuedAdditional information200    PureTech Health plc   Annual Report and Accounts 2023

Our or our Founded Entities’ third-party manufacturers may not take 
the necessary steps to comply with applicable regulations or our or our 
Founded Entities’ specifications, which could cause delays in the delivery 
of our therapeutic candidates. In addition, failure to comply with applicable 
FDA or comparable foreign requirements or later discovery of previously 
unknown problems with our or our Founded Entities’ therapeutics or 
therapeutic candidates or manufacturing processes could result in, 
among other things: warning letters or untitled letters; civil penalties; 
suspension or withdrawal of approvals or clearances; seizures or recalls of 
our or our Founded Entities’ therapeutics; total or partial suspension of 
production or distribution; administrative or judicially imposed sanctions; 
the FDA’s or foreign regulatory authorities’ refusal to grant pending or 
future clearances, certifications, authorizations, or approvals for our or 
our Founded Entities’ therapeutic candidates; clinical holds; refusal to 
permit the import or export of our or our Founded Entities’ therapeutics or 
therapeutic candidates; and criminal prosecution of us or our employees. 
Any of these actions could significantly and negatively impact supply of 
our or our Founded Entities’ therapeutics or therapeutic candidates. If 
any of these events occurs, our reputation could be harmed, we could be 
exposed to product liability claims and we or our Founded Entities could 
lose customers and suffer reduced revenue and increased costs.

Risks Related to Commercialization

If, in the future, we are unable to establish sales and marketing 
capabilities or enter into agreements with third parties to sell and 
market any therapeutic candidates we may develop, we may not be 
successful in commercializing those therapeutic candidates if and when 
they are approved.

We do not have a sales or marketing infrastructure or the capabilities for 
sale, marketing, or distribution of pharmaceutical therapeutics. To achieve 
commercial success for any approved therapeutic for which we retain 
sales and marketing responsibilities, we must either develop a sales and 
marketing organization or outsource these functions to third parties. In the 
future, we may choose to build a focused sales, marketing, and commercial 
support infrastructure to market and sell the therapeutic candidates within 
our Internal Programs, if and when they are approved. We may also elect 
to enter into collaborations or strategic partnerships with third parties to 
engage in commercialization activities with respect to selected therapeutic 
candidates, indications or geographic territories, including territories 
outside the United States, although there is no guarantee we will be able to 
enter into these arrangements even if the intent is to do so.

There are risks involved with both establishing our own commercial 
capabilities and entering into arrangements with third parties to perform 
these services. For example, recruiting and training a sales force or 
reimbursement specialists is expensive and time consuming and could 
delay any therapeutic launch. If the commercial launch of a therapeutic 
candidate for which we recruit a sales force and establish marketing and 
other commercialization capabilities is delayed or does not occur for 
any reason, we would have prematurely or unnecessarily incurred these 
commercialization expenses. This may be costly, and our investment would 
be lost if we cannot retain or reposition commercialization personnel.

Factors that may inhibit our efforts to commercialize any approved 
therapeutic on our own include:

 — the inability to recruit and retain adequate numbers of effective sales, 

marketing, reimbursement, customer service, medical affairs, and other 
support personnel;

 — the inability of sales personnel to obtain access to physicians or persuade 

adequate numbers of physicians to prescribe any future approved 
therapeutics;

 — the inability of reimbursement professionals to negotiate arrangements 
for formulary access, reimbursement, and other acceptance by payors;

 — the inability to price therapeutics at a sufficient price point to ensure an 

adequate and attractive level of profitability;

 — restricted or closed distribution channels that make it difficult to 

distribute our therapeutics to segments of the patient population;

 — the lack of complementary therapeutics to be offered by sales personnel, 
which may put us at a competitive disadvantage relative to companies 
with more extensive therapeutic lines; and

 — unforeseen costs and expenses associated with creating an independent 

commercialization organization.

If we enter into arrangements with third parties to perform sales, 
marketing, commercial support, and distribution services, our therapeutic 
revenue or the profitability of therapeutic revenue may be lower than if 
we were to market and sell any therapeutics we may develop internally. In 
addition, we may not be successful in entering into arrangements with third 
parties to commercialize the therapeutic candidates within our Internal 

Programs or may be unable to do so on terms that are favorable to us or 
them. We may have little control over such third parties, and any of them 
may fail to devote the necessary resources and attention to sell and market 
our therapeutics effectively or may expose us to legal and regulatory risk 
by not adhering to regulatory requirements and restrictions governing 
the sale and promotion of prescription drug therapeutics, including those 
restricting off-label promotion. If we do not establish commercialization 
capabilities successfully, either on our own or in collaboration with third 
parties, we will not be successful in commercializing the therapeutic 
candidates within our Internal Programs, if approved.

Even if any current or future therapeutic candidate of ours receives 
regulatory clearance or approval, it may fail to achieve the degree of 
market acceptance by physicians, patients, third-party payors and others 
in the medical community necessary for commercial success, in which case 
we may not generate significant revenues or become profitable.

We have never commercialized a therapeutic, and even if any current 
or future therapeutic candidate of ours is approved by the appropriate 
regulatory authorities for marketing and sale, it may nonetheless fail to gain 
sufficient market acceptance by physicians, patients, third-party payors 
and others in the medical community. Physicians may be reluctant to take 
their patients off their current medications and switch their treatment 
regimen. Further, patients often acclimate to the treatment regime that 
they are currently taking and do not want to switch unless their physicians 
recommend switching therapeutics or they are required to switch due to 
lack of coverage and adequate reimbursement. In addition, even if we are 
able to demonstrate our Internal Programs’ safety and efficacy to the FDA 
and other regulators, safety or efficacy concerns in the medical community 
may hinder market acceptance.

Efforts to educate the medical community and third-party payors on the 
benefits of the therapeutic candidates within our Internal Programs may 
require significant resources, including management time and financial 
resources, and may not be successful. The degree of market acceptance 
of the therapeutic candidates within our Internal Programs, if approved for 
commercial sale, will depend on a number of factors, including:

 — the efficacy and safety of the therapeutic;

 — the potential advantages of the therapeutic compared to 

competitive therapies;

 — the prevalence and severity of any side effects;

 — whether the therapeutic is designated under physician treatment 

guidelines as a first-, second- or third-line therapy;

 — our ability, or the ability of any future collaborators, to offer the 

therapeutic for sale at competitive prices;

 — the therapeutic’s convenience and ease of administration compared to 

alternative treatments;

 — the willingness of the target patient population to try, and of physicians 

to prescribe, the therapeutic;

 — limitations or warnings, including distribution or use restrictions 

contained in the therapeutic’s approved labelling;

 — the strength of sales, marketing and distribution support;

 — changes in the standard of care for the targeted indications for the 

therapeutic; and

 — availability and adequacy of coverage and reimbursement from 

government payors, managed care plans and other third-party payors.

Sales of medical therapeutics also depend on the willingness of 
physicians to prescribe the treatment, which is likely to be based on 
a determination by these physicians that the therapeutics are safe, 
therapeutically effective and cost effective. In addition, the inclusion 
or exclusion of therapeutics from treatment guidelines established by 
various physician groups and the viewpoints of influential physicians can 
affect the willingness of other physicians to prescribe the treatment. We 
cannot predict whether physicians, physicians’ organizations, hospitals, 
other healthcare providers, government agencies or private insurers will 
determine that our therapeutic is safe, therapeutically effective and cost 
effective as compared with competing treatments. If any therapeutic 
candidates we develop do not achieve an adequate level of acceptance, 
we may not generate significant therapeutic revenue, and we may not 
become profitable.

Any failure by any current or future therapeutic candidate of ours that 
obtains regulatory approval to achieve market acceptance or commercial 
success would adversely affect our business prospects. In addition, any 
negative perception of one of our Founded Entities or any therapeutic 
candidates marketed or commercialized by them may adversely affect 
our reputation in the marketplace or among industry participants and our 
business prospects.

Risk Factor Annex continuedAdditional informationPureTech Health plc   Annual Report and Accounts 2023    201  

The incidence and prevalence for target patient populations of our 
therapeutic candidates have not been established with precision. If the 
market opportunities for our therapeutic candidates are smaller than we 
estimate, or if any approval that we obtain is based on a narrower definition 
of the patient population, our revenue and ability to achieve profitability 
may be materially adversely affected. 

The precise incidence and prevalence for all the conditions we aim to 
address with our therapeutic candidates are unknown and cannot be 
precisely determined. Our projections of both the number of people who 
have these diseases, as well as the subset of people with these diseases 
who have the potential to benefit from treatment with our therapeutic 
candidates, are based on beliefs and estimates. These estimates have 
been derived from a variety of sources, including the scientific literature, 
surveys of clinics, patient foundations or market research, and may prove 
to be incorrect. Further, new trials may change the estimated incidence or 
prevalence of these diseases. 

The total addressable market across all of our therapeutic candidates 
will ultimately depend upon, among other things, the diagnosis criteria 
included in the final label for each of our therapeutic candidates approved 
for sale for these indications, acceptance by the medical community and 
patient access, drug pricing and reimbursement. The number of patients 
in the United States and other major markets and elsewhere may turn out 
to be lower than expected, patients may not be otherwise amenable to 
treatment with our products or new patients may become increasingly 
difficult to identify or gain access to, all of which would adversely affect our 
results of operations and our business. Further, even if we obtain significant 
market share for our therapeutic candidates, if the potential target 
populations are very small, we may never achieve profitability despite 
obtaining such significant market share.

The insurance coverage and reimbursement status of newly-approved 
therapeutics is uncertain. The therapeutic candidates within our Internal 
Programs may become subject to unfavorable pricing regulations, 
third-party coverage and reimbursement practices, or healthcare reform 
initiatives, which would harm our business. Failure to obtain or maintain 
coverage and adequate reimbursement for new or current therapeutics 
could limit our ability to market those therapeutics and decrease our ability 
to generate revenue.

The regulations that govern marketing approvals, pricing, coverage, and 
reimbursement for new drugs and other medical therapeutics vary widely 
from country to country. In the United States, healthcare reform legislation 
may significantly change the approval requirements in ways that could 
involve additional costs and cause delays in obtaining approvals. Some 
countries require approval of the sale price of a therapeutic before it can 
be marketed. In many countries, the pricing review period begins after 
marketing or therapeutic licensing approval is granted. In some foreign 
markets, pricing remains subject to continuing governmental control even 
after initial approval is granted. As a result, we might obtain marketing 
approval for a therapeutic in a particular country, but then be subject to 
price regulations that delay our commercial launch of the therapeutic, 
possibly for lengthy time periods, and negatively impact the revenue 
we are able to generate from the sale of the therapeutic in that country. 
Adverse pricing limitations may hinder our ability to recoup our investment 
in one or more therapeutics or therapeutic candidates, even if any 
therapeutic candidates we may develop obtain marketing approval.

Our ability to successfully commercialize our therapeutics and therapeutic 
candidates also will depend in part on the extent to which coverage and 
adequate reimbursement for these therapeutics and related treatments 
will be available from government health administration authorities, 
private health insurers, and other organizations. Government authorities 
and third-party payors, such as private health insurers and health 
maintenance organizations, decide which medications they will pay for 
and establish reimbursement levels. The availability of coverage and 
extent of reimbursement by governmental and private payors is essential 
for most patients to be able to afford treatments such as gene therapy 
therapeutics. Sales of these or other therapeutic candidates that we 
may identify will depend substantially, both domestically and abroad, 
on the extent to which the costs of the therapeutic candidates within our 
Internal Programs will be paid by health maintenance, managed care, 
pharmacy benefit and similar healthcare management organizations, or 
reimbursed by government health administration authorities, private health 
coverage insurers and other third-party payors. If coverage and adequate 
reimbursement is not available, or is available only to limited levels, we may 
not be able to successfully commercialize our therapeutics or therapeutic 
candidates. Even if coverage is provided, the approved reimbursement 
amount may not be high enough to allow us to establish or maintain 
pricing sufficient to realize a sufficient return on our investment. A primary 
trend in the U.S. healthcare industry and elsewhere is cost containment. 
Government authorities and third-party payors have attempted to control 

costs by limiting coverage and the amount of reimbursement for particular 
medications. In many countries, the prices of medical therapeutics are 
subject to varying price control mechanisms as part of national health 
systems. In general, the prices of medicines under such systems are 
substantially lower than in the United States. Other countries allow 
companies to fix their own prices for medicines, but monitor and control 
company profits. Additional foreign price controls or other changes in 
pricing regulation could restrict the amount that we are able to charge for 
the therapeutic candidates within our Internal Programs. Accordingly, in 
markets outside the United States, the reimbursement for therapeutics 
may be reduced compared with the United States and may be insufficient 
to generate commercially reasonable revenues and profits.

There is also significant uncertainty related to the insurance coverage 
and reimbursement of newly approved therapeutics and coverage may 
be more limited than the purposes for which the medicine is approved 
by the FDA or comparable foreign regulatory authorities. In the United 
States, the principal decisions about reimbursement for new medicines 
are typically made by the Centers for Medicare & Medicaid Services, or 
CMS, an agency within the U.S. Department of Health and Human Services. 
CMS decides whether and to what extent a new medicine will be covered 
and reimbursed under Medicare and private payors tend to follow CMS to 
a substantial degree. No uniform policy of coverage and reimbursement 
for therapeutics exists among third-party payors and coverage and 
reimbursement levels for therapeutics can differ significantly from payor 
to payor. As a result, the coverage determination process is often a time 
consuming and costly process that may require us to provide scientific and 
clinical support for the use of our therapeutics to each payor separately, 
with no assurance that coverage and adequate reimbursement will be 
applied consistently or obtained in the first instance. It is difficult to predict 
what CMS will decide with respect to reimbursement for fundamentally 
novel therapeutics such as ours, as there is no body of established 
practices and precedents for these new therapeutics. Reimbursement 
agencies in Europe may be more conservative than CMS. For example, a 
number of cancer drugs have been approved for reimbursement in the 
United States and have not been approved for reimbursement in certain 
European countries. Moreover, eligibility for reimbursement does not 
imply that any drug will be paid for in all cases or at a rate that covers 
our costs, including research, development, manufacture, sale, and 
distribution. Interim reimbursement levels for new drugs, if applicable, may 
also not be sufficient to cover our costs and may not be made permanent. 
Reimbursement rates may vary according to the use of the drug and the 
clinical setting in which it is used, may be based on reimbursement levels 
already set for lower cost drugs and may be incorporated into existing 
payments for other services. Our inability to promptly obtain coverage 
and profitable payment rates from both government-funded and private 
payors for any approved therapeutics we may develop could have a 
material adverse effect on our operating results, our ability to raise capital 
needed to commercialize therapeutic candidates, and our overall financial 
condition. As noted above, in the United States we plan to have various 
programs to help patients afford our therapeutics, including patient 
assistance programs and co-pay coupon programs for eligible patients.

Net prices for drugs may be reduced by mandatory discounts or rebates 
required by government healthcare programs or private payors and by 
any future relaxation of laws that presently restrict imports of drugs from 
countries where they may be sold at lower prices than in the United States. 
Our inability to promptly obtain coverage and profitable reimbursement 
rates third-party payors for any approved therapeutics that we develop 
could have a material adverse effect on our operating results, our ability 
to raise capital needed to commercialize therapeutics and our overall 
financial condition.

Increasingly, third-party payors are requiring that pharmaceutical 
companies provide them with predetermined discounts from list prices 
and are challenging the prices charged for medical therapeutics. We 
cannot be sure that reimbursement will be available for any therapeutic 
candidate that we commercialize and, if reimbursement is available, the 
level of reimbursement. Reimbursement may impact the demand for, or 
the price of, any therapeutic or therapeutic candidate for which we obtain 
marketing approval. In order to obtain reimbursement, physicians may 
need to show that patients have superior treatment outcomes with our 
therapeutics compared to standard of care drugs, including lower-priced 
generic versions of standard of care drugs. We expect to experience 
pricing pressures in connection with the sale of any of the therapeutic 
candidates within our Internal Programs, due to the trend toward managed 
healthcare, the increasing influence of health maintenance organizations 
and additional legislative changes. The downward pressure on healthcare 
costs in general, particularly prescription drugs and surgical procedures 
and other treatments, has become very intense. As a result, increasingly 
high barriers are being erected to the entry of new therapeutics. 
Additionally, we may develop companion diagnostic tests for use with our

Internal Programs or our Founded Entities’ therapeutic candidates. We, 
or our Founded Entities or our collaborators may be required to obtain 
coverage and reimbursement for these tests separate and apart from 
the coverage and reimbursement we seek for our Internal Programs or 
our Founded Entities’ therapeutic candidates, once approved. Even if 
we or our Founded Entities obtain regulatory approval or clearance for 
such companion diagnostics, there is significant uncertainty regarding 
our ability to obtain coverage and adequate reimbursement for the same 
reasons applicable to our Internal Programs or our Founded Entities’ 
therapeutic candidates. Medicare reimbursement methodologies, whether 
under Part A, Part B, or clinical laboratory fee schedule may be amended 
from time to time, and we cannot predict what effect any change to these 
methodologies would have on any therapeutic candidate or companion 
diagnostic for which we receive approval.

 — the federal Health Insurance Portability and Accountability Act of 

1996, or HIPAA, which created additional federal criminal statutes that 
prohibit knowingly and willfully executing, or attempting to execute, a 
scheme to defraud any healthcare benefit program or obtain, by means 
of false or fraudulent pretenses, representations, or promises, any of 
the money or property owned by, or under the custody or control of, 
any healthcare benefit program, regardless of the payor (e.g., public or 
private) and knowingly and willfully falsifying, concealing or covering 
up by any trick or device a material fact or making any materially false 
statements in connection with the delivery of, or payment for, healthcare 
benefits, items or services relating to healthcare matters. Similar to the 
federal Anti-Kickback Statute, a person or entity can be found guilty of 
violating HIPAA without actual knowledge of the statute or specific intent 
to violate it;

Risks Related to Compliance with Healthcare Laws

If we fail to comply with healthcare laws, we could face substantial 
penalties and our business, operations and financial conditions could be 
adversely affected.

Healthcare providers, physicians and third-party payors in the United 
States and elsewhere play a primary role in the recommendation and 
prescription of pharmaceutical therapeutics. Arrangements with healthcare 
providers, third-party payors and customers can expose pharmaceutical 
manufacturers to broadly applicable fraud and abuse and other healthcare 
laws and regulations, including, without limitation, the federal Anti-
Kickback Statute and the federal False Claims Act, or the FCA, which 
may constrain the business or financial arrangements and relationships 
through which such companies sell, market and distribute pharmaceutical 
therapeutics. In particular, the promotion, sales and marketing of 
healthcare items and services, as well as certain business arrangements in 
the healthcare industry, are subject to extensive laws designed to prevent 
fraud, kickbacks, self-dealing and other abusive practices. These laws and 
regulations may restrict or prohibit a wide range of ownership, pricing, 
discounting, marketing and promotion, structuring and commission(s), 
certain customer incentive programs and other business arrangements 
generally. Activities subject to these laws also involve the improper use of 
information obtained in the course of patient recruitment for clinical trials. 
The applicable federal and state healthcare laws and regulations laws that 
may affect our ability to operate include, but are not limited to:

 — the federal Anti-Kickback Statute, which prohibits, among other things, 
persons from knowingly and willfully soliciting, receiving, offering or 
paying any remuneration (including any kickback, bribe, or rebate), 
directly or indirectly, overtly or covertly, in cash or in kind, to induce, or 
in return for, either the referral of an individual, or the purchase, lease, 
order or recommendation of any good, facility, item or service for which 
payment may be made, in whole or in part, under a federal healthcare 
program, such as the Medicare and Medicaid programs. A person or 
entity does not need to have actual knowledge of the statute or specific 
intent to violate it in order to have committed a violation. Violations are 
subject to civil and criminal fines and penalties for each violation, plus 
up to three times the remuneration involved, imprisonment of up to 
ten years, and exclusion from government healthcare programs. The 
Anti-Kickback Statute has been interpreted to apply to arrangements 
between pharmaceutical manufacturers, on the one hand, and 
prescribers, purchasers and formulary managers, on the other;

 — federal civil and criminal false claims laws and civil monetary penalty laws, 
including the False Claims Act, which impose criminal and civil penalties, 
including through civil “qui tam” or “whistleblower” actions, against 
individuals or entities for, among other things, knowingly presenting, or 
causing to be presented, claims for payment or approval from Medicare, 
Medicaid, or other federal health care programs that are false or 
fraudulent; knowingly making or causing a false statement material to 
a false or fraudulent claim or an obligation to pay money to the federal 
government; or knowingly concealing or knowingly and improperly 
avoiding or decreasing such an obligation. Manufacturers can be held 
liable under the FCA even when they do not submit claims directly to 
government payors if they are deemed to “cause” the submission of false 
or fraudulent claims. The government may assert that a claim including 
items or services resulting from a violation of the federal Anti-Kickback 
Statute constitutes a false or fraudulent claim for purposes of the FCA. 
The FCA also permits a private individual acting as a “whistleblower” to 
bring actions on behalf of the federal government alleging violations of 
the FCA and to share in any monetary recovery;

 — the federal civil monetary penalties laws, which impose civil fines for, 
among other things, the offering or transfer or remuneration to a 
Medicare or state healthcare program beneficiary if the person knows 
or should know it is likely to influence the beneficiary’s selection of a 
particular provider, practitioner, or supplier of services reimbursable by 
Medicare or a state healthcare program, unless an exception applies;

 — the federal Physician Payments Sunshine Act, created under the ACA, 

and its implementing regulations, which require manufacturers of drugs, 
devices, biologicals and medical supplies for which payment is available 
under Medicare, Medicaid or the Children’s Health Insurance Program 
(with certain exceptions) to report annually to the U.S. Department 
of Health and Human Services, or HHS, under the Open Payments 
Program, information related to payments or other transfers of value 
made to physicians (defined to include doctors, dentists, optometrists, 
podiatrists and chiropractors), certain non-physician providers (physician 
assistants, nurse practitioners, clinical nurse specialists, certified nurse 
anaesthetists, anaesthesiologist assistants and certified nurse midwives), 
and teaching hospitals, as well as ownership and investment interests 
held by physicians and their immediate family members;

 — federal consumer protection and unfair competition laws, which 

broadly regulate marketplace activities and activities that potentially 
harm consumers;

 — federal price reporting laws, which require manufacturers to calculate 

and report complex pricing metrics to government programs, where such 
reported prices may be used in the calculation of reimbursement and/or 
discounts on approved therapeutics; and

 — analogous state and foreign laws and regulations, such as state and 
foreign anti-kickback, false claims, consumer protection and unfair 
competition laws which may apply to pharmaceutical business practices, 
including but not limited to, research, distribution, sales and marketing 
arrangements as well as submitting claims involving healthcare items 
or services reimbursed by any third-party payer, including commercial 
insurers; state laws that require pharmaceutical companies to comply 
with the pharmaceutical industry’s voluntary compliance guidelines 
and the relevant compliance guidance promulgated by the federal 
government that otherwise restricts payments that may be made to 
healthcare providers and other potential referral sources; state laws that 
require drug manufacturers to file reports with states regarding pricing 
and marketing information, such as the tracking and reporting of gifts, 
compensations and other remuneration and items of value provided to 
healthcare professionals and entities; and state and local laws requiring 
the registration of pharmaceutical sales representatives.

Because of the breadth of these laws and the narrowness of the statutory 
exceptions and regulatory safe harbors available, it is possible that some 
of our business activities, including compensation of physicians with stock 
or stock options, could, despite efforts to comply, be subject to challenge 
under one or more of such laws. Additionally, FDA or foreign regulators 
may not agree that we have mitigated any risk of bias in our clinical 
trials due to payments or equity interests provided to investigators or 
institutions which could limit a regulator’s acceptance of those clinical trial 
data in support of a marketing application. Moreover, efforts to ensure that 
our business arrangements will comply with applicable healthcare laws may 
involve substantial costs. It is possible that governmental and enforcement 
authorities will conclude that our business practices may not comply with 
current or future statutes, regulations or case law interpreting applicable 
fraud and abuse or other healthcare laws and regulations. If any such 
actions are instituted against us, and we are not successful in defending 
ourselves or asserting our rights, those actions could have a significant 
impact on our business, including the imposition of significant civil, 
criminal and administrative penalties, damages, disgorgement, monetary 
fines, exclusion from participation in Medicare, Medicaid and other federal 
healthcare programs, integrity and oversight agreements to resolve 
allegations of non-compliance, contractual damages, reputational harm, 
diminished profits and future earnings, and curtailment or restructuring of 

Risk Factor Annex continuedAdditional informationPureTech Health plc   Annual Report and Accounts 2023    203  

our operations, any of which could adversely affect our ability to operate 
our business and our results of operations. In addition, the approval 
and commercialization of any of the therapeutic candidates within our 
Internal Programs outside the United States will also likely subject us 
to foreign equivalents of the healthcare laws mentioned above, among 
other foreign laws.

Failure to comply with data protection laws and regulations could lead 
to government enforcement actions (which could include civil or criminal 
penalties), private litigation, and/or adverse publicity and could negatively 
affect our operating results and business.

We and any potential collaborators may be subject to federal, state, and 
foreign data protection laws and regulations (i.e., laws and regulations that 
address privacy and data security). In the United States, numerous federal 
and state laws and regulations, including federal health information privacy 
laws, state data breach notification laws, state health information privacy 
laws, and federal and state consumer protection laws (e.g., Section 5 of the 
Federal Trade Commission Act), that govern the collection, use, disclosure 
and protection of health-related and other personal information could 
apply to our operations or the operations of our collaborators. In addition, 
we may obtain health information from third parties (including research 
institutions from which we obtain clinical trial data) that are subject to 
privacy and security requirements under HIPAA, as amended. Depending 
on the facts and circumstances, we could be subject to civil, criminal, and 
administrative penalties if we knowingly obtain, use, or disclose individually 
identifiable health information maintained by a HIPAA-covered entity in a 
manner that is not authorized or permitted by HIPAA.

As our operations and business grow, we may become subject to or 
affected by new or additional data protection laws and regulations and 
face increased scrutiny or attention from regulatory authorities. In the 
United States, certain states have adopted data privacy and security laws 
and regulations, which govern the privacy, processing and protection of 
health-related and other personal information. Such laws and regulations 
will be subject to interpretation by various courts and other governmental 
authorities, thus creating potentially complex compliance issues for us and 
our future customers and strategic partners. For example, the California 
Consumer Privacy Act of 2018, as amended by the California Privacy Rights 
Act, or collectively, the CCPA, requires covered businesses that process 
the personal information of California residents to, among other things: (i) 
provide certain disclosures to California residents regarding the business’s 
collection, use, and disclosure of their personal information; (ii) receive 
and respond to requests from California residents to access, delete, and 
correct their personal information, or to opt out of certain disclosures of 
their personal information; and (iii) enter into specific contractual provisions 
with service providers that process California resident personal information 
on the business’s behalf. Additional compliance investment and potential 
business process changes may also be required. Similar laws have passed 
in other states and are continuing to be proposed at the state and federal 
level, reflecting a trend toward more stringent privacy legislation in 
the United States. The enactment of such laws could have potentially 
conflicting requirements that would make compliance challenging. In the 
event that we are subject to or affected by HIPAA, the CCPA, the CPRA or 
other domestic privacy and data protection laws, any liability from failure 
to comply with the requirements of these laws could adversely affect our 
financial condition.

Further, in the event we decide to conduct clinical trials or continue to 
enroll subjects in our ongoing or future clinical trials in the European 
Economic Area, or EEA, or the United Kingdom, UK, we may be subject to 
additional privacy restrictions. The EU General Data Protection Regulation 
2016/679, or GDPR, and the UK General Data Protection Regulation and the 
Data Protection Act 2018, or the UK GDPR, could impose comprehensive 
data privacy compliance obligations in relation to our collection and use 
of personal data, including a principle of accountability and the obligation 
to demonstrate compliance through policies, procedures, training and 
audit, as well as regulating cross-border transfers of personal data out 
of the EEA and the UK. In relation to data transfers from the EEA to the 
United States, the EU-US Data Privacy Framework, or DPF, was approved 
by the European Commission in July 2023 as an effective EU GDPR data 
transfer mechanism to U.S. entities self-certified under the DPF. The 
UK Extension to the DPF followed in October 2023, as an effective UK 
GDPR data transfer mechanism to U.S. entities self-certified under the 
UK Extension to the DPF. In relation to such cross border transfers of 
personal data, we expect the existing legal complexity and uncertainty 
regarding international personal data transfers to continue. In particular, 
we expect the European Commission approval of the current DPF to be 
challenged and international transfers to the United States and to other 
jurisdictions more generally to continue to be subject to enhanced scrutiny 
by regulators. As the regulatory guidance and enforcement landscape in 
relation to data transfers continue to develop, we could suffer additional 
costs, complaints and/or regulatory investigations or fines; we may have to 

stop using certain tools and vendors and make other operational changes; 
we may have to implement alternative data transfer mechanisms under the 
GDPR and/ or take additional compliance and operational measures; and/
or it could otherwise affect the manner in which we provide our services 
and could adversely affect our business, operations and financial condition. 
Companies that must comply with the GDPR and UK GDPR face increased 
compliance obligations and risk, including more robust regulatory 
enforcement of data protection requirements and potential fines for 
noncompliance of up to €20 million under the GDPR and £17.5 million under 
the UK GDPR or 4% of the annual global revenues of the noncompliant 
undertaking, whichever is greater. The existence of parallel regimes under 
the GDPR and UK GDPR, and divergence in respect of implementing or 
supplementary laws across the EEA and UK in certain areas, means that 
we could be subject to potentially overlapping or divergent enforcement 
actions for certain actual or perceived violations. 

Failure to comply with these laws and regulations could result in 
government enforcement actions (which could include civil, criminal and 
administrative penalties), private litigation, and/or adverse publicity and 
could negatively affect our operating results and business. Moreover, 
clinical trial subjects, employees and other individuals about whom we 
or our potential collaborators obtain personal information, as well as the 
providers who share this information with us, may limit our ability to collect, 
use and disclose the information. Claims that we have violated individuals’ 
privacy rights, failed to comply with data protection laws, or breached our 
contractual obligations, even if we are not found liable, could be expensive 
and time-consuming to defend and could result in adverse publicity that 
could harm our business.

Healthcare legislative measures aimed at reducing healthcare costs may 
have a material adverse effect on our business and results of operations.

The United States and many foreign jurisdictions have enacted or 
proposed legislative and regulatory changes affecting the healthcare 
system that could prevent or delay marketing approval of the therapeutic 
candidates within our Internal Programs or our Founded Entities’ 
therapeutic candidates or any future therapeutic candidates, restrict or 
regulate post-approval activities and affect our or our Founded Entities’ 
ability to profitably sell any therapeutic for which we or our Founded 
Entities obtain marketing approval. Changes in regulations, statutes or 
the interpretation of existing regulations could impact our or our Founded 
Entities’ business in the future by requiring, for example: (i) changes to our 
manufacturing arrangements; (ii) additions or modifications to therapeutic 
labeling; (iii) the recall or discontinuation of our therapeutics; or (iv) 
additional record-keeping requirements. If any such changes were to be 
imposed, they could adversely affect the operation of our business.

In the United States, there have been and continue to be a number of 
legislative initiatives and judicial challenges to contain healthcare costs. 
For example, in March 2010, the Affordable Care Act, or the ACA, was 
passed, which substantially changed the way healthcare is financed by 
both governmental and private insurers, and significantly impacted the 
U.S. pharmaceutical industry. The ACA, among other things, subjects 
biological therapeutics to potential competition by lower-cost biosimilars, 
addresses a new methodology by which rebates owed by manufacturers 
under the Medicaid Drug Rebate Program are calculated for drugs that are 
inhaled, infused, instilled, implanted or injected, increases the minimum 
Medicaid rebates owed by manufacturers under the Medicaid Drug 
Rebate Program and extends the rebate program to individuals enrolled in 
Medicaid managed care organizations, establishes annual fees and taxes 
on manufacturers of certain branded prescription drugs, and creates a new 
Medicare Part D coverage gap discount program, in which manufacturers 
must agree to offer 70 percent point-of-sale discounts off negotiated 
prices of applicable brand drugs to eligible beneficiaries during their 
coverage gap period, as a condition for the manufacturer’s outpatient 
drugs to be covered under Medicare Part D. Since the enactment of the 
ACA, there have been numerous judicial, administrative, executive, and 
legislative challenges to certain aspects of the ACA. On June 17, 2021, 
the U.S. Supreme Court dismissed the most recent judicial challenge 
to the ACA brought by several states without specifically ruling on the 
constitutionality of the ACA.

Payment methodologies may be subject to changes in healthcare 
legislation and regulatory challenges. For example, in order for a drug 
therapeutic to receive federal reimbursement under the Medicaid or 
Medicare Part B programs or to be sold directly to U.S. government 
agencies, the manufacturer must extend discounts to entities eligible 
to participate in the 340B drug pricing program. In December 2018, the 
CMS published a final rule permitting further collections and payments to 
and from certain ACA qualified health plans and health insurance issuers 
under the ACA risk adjustment program in response to the outcome 
of the federal district court litigation regarding the method CMS uses 
to determine this risk adjustment. Since then, the ACA risk adjustment 
program payment parameters have been updated annually.

Risk Factor Annex continuedAdditional information204    PureTech Health plc   Annual Report and Accounts 2023

In addition, other legislative changes have been proposed and adopted 
in the United States since the ACA was enacted. In August 2011, the 
Budget Control Act of 2011, among other things, resulted in aggregate 
reductions of Medicare payments to providers, which went into effect in 
2013, and, due to subsequent legislative amendments, will remain in effect 
through 2032, with the exception of a temporary suspension from May 1, 
2020 through March 31, 2022, unless additional Congressional action is 
taken. The American Taxpayer Relief Act of 2012 further reduced Medicare 
payments to several types of providers, including hospitals and cancer 
treatment centers, and increased the statute of limitations period for 
the government to recover overpayments to providers from three to five 
years. In addition, in March 2021, Congress enacted the American Rescue 
Plan Act of 2021, which, among other things, eliminated the statutory cap 
on drug manufacturers’ Medicaid Drug Rebate Program rebate liability, 
effective January 1, 2024.

There has been increasing legislative and enforcement interest in the 
United States with respect to drug pricing practices. Specifically, there 
have been several recent U.S. Congressional inquiries and proposed 
federal and state legislation designed to, among other things, bring more 
transparency to drug pricing, reduce the cost of prescription drugs under 
Medicare, review the relationship between pricing and manufacturer 
patient programs, and reform government program reimbursement 
methodologies for drugs. On August 16, 2022, the Inflation Reduction 
Act of 2022, or IRA, was signed into law. Among other things, the IRA 
requires manufacturers of certain drugs to engage in price negotiations 
with Medicare (beginning in 2026), imposes rebates under Medicare Part 
B and Medicare Part D to penalize price increases that outpace inflation 
(first due in 2023), and replaces the Part D coverage gap discount program 
with a new discounting program (beginning in 2025). The IRA permits the 
Secretary of the Department of Health and Human Services to implement 
many of these provisions through guidance, as opposed to regulation, 
for the initial years. On August 29, 2023, HHS announced the list of the 
first ten drugs that will be subject to price negotiations, although the 
Medicare drug price negotiation program is currently subject to legal 
challenges. For that and other reasons, it is currently unclear how the IRA 
will be effectuated. 

At the state level, legislatures have increasingly passed legislation and 
implemented regulations designed to control pharmaceutical and 
biological therapeutic pricing, including price or patient reimbursement 
constraints, discounts, restrictions on certain therapeutic access and 
marketing cost disclosure and transparency measures, and, in some 
cases, designed to encourage importation from other countries and bulk 
purchasing. In addition, regional healthcare authorities and individual 
hospitals are increasingly using bidding procedures to determine what 
pharmaceutical therapeutics and which suppliers will be included in their 
prescription drug and other healthcare programs. Furthermore, there has 
been increased interest by third-party payors and governmental authorities 
in reference pricing systems and publication of discounts and list prices.

There have been, and likely will continue to be, legislative and regulatory 
proposals at the foreign, federal and state levels directed at containing or 
lowering the cost of healthcare. The implementation of cost containment 
measures or other healthcare reforms may prevent us from being able to 
generate revenue, attain profitability, or commercialize our therapeutic. 
Such reforms could have an adverse effect on anticipated revenue from 
therapeutic candidates that we may successfully develop and for which 
we may obtain regulatory approval and may affect our overall financial 
condition and ability to develop therapeutic candidates. We cannot predict 
the initiatives that may be adopted in the future. The continuing efforts of 
the government, insurance companies, managed care organizations and 
other payors of healthcare services to contain or reduce costs of healthcare 
and/or impose price controls may adversely affect:

 — the demand for the therapeutic candidates within our Internal Programs 

or our Founded Entities’ therapeutic candidates, if approved;

 — our ability to receive or set a price that we believe is fair for our 

therapeutics;

 — our ability to generate revenue and achieve or maintain profitability;

 — the amount of taxes that we are required to pay; and

 — the availability of capital.

Other healthcare reform measures may be adopted in the future, and may 
result in additional reductions in Medicare and other healthcare funding, 
more rigorous coverage criteria, lower reimbursement, and new payment 
methodologies. This could lower the price that we receive for any approved 
therapeutic. Any denial in coverage or reduction in reimbursement from 
Medicare or other government-funded programs may result in a similar 
denial or reduction in payments from private payors, which may prevent 
us from being able to generate sufficient revenue, attain profitability or 
commercialize the therapeutic candidates within our Internal Programs or 
our Founded Entities’ therapeutic candidates, if approved. Litigation and 
legislative efforts to change or repeal the ACA are likely to continue, with 
unpredictable and uncertain results.

In the EU, similar developments may affect our ability to profitably 
commercialize our therapeutic candidates, if approved. On December 
13, 2021, Regulation No 2021/2282 on Health Technology Assessment, or 
HTA, amending Directive 2011/24/EU, was adopted. While the Regulation 
entered into force in January 2022, it will only begin to apply from January 
2025 onwards, with preparatory and implementation-related steps to take 
place in the interim. Once applicable, it will have a phased implementation 
depending on the concerned products. The Regulation intends to boost 
cooperation among EU member states in assessing health technologies, 
including new medicinal products as well as certain high-risk medical 
devices, and provide the basis for cooperation at the EU level for joint 
clinical assessments in these areas. It will permit EU member states to 
use common HTA tools, methodologies, and procedures across the EU, 
working together in four main areas, including joint clinical assessment of 
the innovative health technologies with the highest potential impact for 
patients, joint scientific consultations whereby developers can seek advice 
from HTA authorities, identification of emerging health technologies 
to identify promising technologies early, and continuing voluntary 
cooperation in other areas. Individual EU member states will continue to 
be responsible for assessing non-clinical (e.g., economic, social, ethical) 
aspects of health technology, and making decisions on pricing and 
reimbursement.

Risks Related to Competition

We face significant competition in an environment of rapid technological 
and scientific change, and there is a possibility that our competitors 
may achieve regulatory approval before us or develop therapies that are 
safer, more advanced or more effective than ours, which may negatively 
impact our ability to successfully market or commercialize any therapeutic 
candidates we may develop and ultimately harm our financial condition.

The development and commercialization of new drug therapeutics is highly 
competitive. We may face competition with respect to any therapeutic 
candidates that we seek to develop or commercialize in the future from 
major pharmaceutical companies, specialty pharmaceutical companies, 
and biotechnology companies worldwide. Potential competitors also 
include academic institutions, government agencies, and other public 
and private research organizations that conduct research, seek patent 
protection, and establish collaborative arrangements for research, 
development, manufacturing, and commercialization.

There are a number of major pharmaceutical and biotechnology companies 
that are currently pursuing the development and commercialization of 
potential medicines targeting similar treatment areas as we are. If any of 
our competitors receive FDA or foreign regulatory authorities approval 
before we do, the therapeutic candidates within our Internal Programs 
would not be the first treatment on the market, and our market share may 
be limited. In addition to competition from other companies targeting 
our target indications, any therapeutics we may develop may also face 
competition from other types of therapies.

Many of our current or potential competitors, either alone or with their 
strategic partners, have:

 — greater financial, technical, and human resources than we have 

at every stage of the discovery, development, manufacture, and 
commercialization of therapeutics;

 — more extensive resources for preclinical testing, conducting clinical trials, 
obtaining regulatory approvals, and in manufacturing, marketing, and 
selling drug therapeutics;

 — therapeutics that have been approved or are in late stages of 

development; and

 — collaborative arrangements in our target markets with leading companies 

and research institutions.

Mergers and acquisitions in the pharmaceutical and biotechnology 
industries may result in even more resources being concentrated among a 
smaller number of our competitors. Smaller or early-stage companies may 
also prove to be significant competitors, particularly through collaborative 
arrangements with large and established companies. These competitors 
also compete with us in recruiting and retaining qualified scientific 
and management personnel and establishing clinical trial sites and 
patient registration for clinical trials, as well as in acquiring technologies 
complementary to, or necessary for, our programs. Our commercial 
opportunity could be reduced or eliminated if our competitors develop 
and commercialize therapeutics that are safer, more effective, have fewer 
or less severe side effects, are more convenient, or are less expensive than 
any therapeutics that we may develop. Furthermore, currently approved 
therapeutics could be discovered to have application for treatment of our 
targeted disease indications or similar indications, which could give such 
therapeutics significant regulatory and market timing advantages over the 
therapeutic candidates within our Internal Programs. Our competitors may 
also obtain FDA, EMA or other comparable foreign regulatory approval for 
their therapeutics more rapidly than we may obtain approval for ours and 

Risk Factor Annex continuedAdditional informationmay obtain orphan therapeutic exclusivity from the FDA for indications 
that we are targeting, which could result in our competitors establishing a 
strong market position before we are able to enter the market. Additionally, 
therapeutics or technologies developed by our competitors may render 
our potential therapeutic candidates uneconomical or obsolete and we 
may not be successful in marketing any therapeutic candidates we may 
develop against competitors.

In addition, we could face litigation or other proceedings with respect to 
the scope, ownership, validity and/or enforceability of our patents relating 
to our competitors’ therapeutics and our competitors may allege that our 
therapeutics infringe, misappropriate or otherwise violate their intellectual 
property. The availability of our competitors’ therapeutics could limit the 
demand, and the price we are able to charge, for any therapeutics that we 
may develop and commercialize.

The therapeutic candidates within our Internal Programs or our Founded 
Entities’ therapeutic candidates for which we or our Founded Entities 
intend to seek approval as biologic therapeutics may face competition 
sooner than anticipated.

If we or our Founded Entities are successful in achieving regulatory 
approval to commercialize any biologic therapeutic candidate we or 
our Founded Entities develop alone or with collaborators, it may face 
competition from biosimilar therapeutics. In the United States, certain of 
the therapeutic candidates within our Internal Programs and our Founded 
Entities’ therapeutic candidates are regulated by the FDA as biologic 
therapeutics subject to approval under the BLA pathway. The Biologics 
Price Competition and Innovation Act of 2009, or BPCIA, created an 
abbreviated pathway for the approval of biosimilar and interchangeable 
biologic therapeutics following the approval of an original BLA. The 
abbreviated regulatory pathway establishes legal authority for the 
FDA to review and approve biosimilar biologics, including the possible 
designation of a biosimilar as “interchangeable” based on its similarity 
to an existing brand therapeutic. Under the BPCIA, an application for a 
biosimilar therapeutic may not be submitted until four years following 
the date that the reference therapeutic was first licensed by the FDA. 
In addition, the approval of a biosimilar therapeutic may not be made 
effective by the FDA until 12 years after the reference therapeutic was 
first licensed by the FDA. During this 12-year period of exclusivity, another 
company may still market a competing version of the reference therapeutic 
if the FDA approves a full BLA for the competing therapeutic containing 
the sponsor’s own preclinical data and data from adequate and well-
controlled clinical trials to demonstrate the safety, purity and potency of 
their therapeutic. In the EU, upon receiving a marketing authorization, new 
biological entities generally receive eight years of data exclusivity and 
an additional two years of market exclusivity. If granted, data exclusivity 
prevents regulatory authorities in the EU from referencing the innovator’s 
data to assess a biosimilar application. During the additional two-year 
period of market exclusivity, a biosimilar marketing authorization can be 
submitted, and the innovator’s data may be referenced, but no biosimilar 
product can be marketed until the expiration of the market exclusivity.

We believe that any of the therapeutic candidates within our Internal 
Programs or our Founded Entities’ therapeutic candidates that are 
approved as a biological therapeutic under a BLA should qualify for the 12-
year period of exclusivity. However, there is a risk that this exclusivity could 
be shortened due to congressional action or otherwise, or that the FDA 
will not consider such therapeutic candidates to be reference therapeutics 
for competing therapeutics, potentially creating the opportunity for 
generic competition sooner than anticipated. Other aspects of the BPCIA, 
some of which may impact the BPCIA exclusivity provisions, have also 
been the subject of recent litigation. Moreover, the extent to which a 
biosimilar therapeutic, once approved, will be substituted for any one of 
our, our Founded Entities’ or our collaborators’ reference therapeutics 
in a way that is similar to traditional generic substitution for non-biologic 
therapeutics is not yet clear, and will depend on a number of marketplace 
and regulatory factors that are still developing. If competitors are able to 
obtain marketing approval for biosimilars referencing any therapeutics that 
we or our Founded Entities develop alone or with collaborators that may 
be approved, such therapeutics may become subject to competition from 
such biosimilars, with the attendant competitive pressure and potential 
adverse consequences.

Risks Related to Reliance on Third Parties

We are currently party to and may seek to enter into additional 
collaborations, licenses and other similar arrangements and may not be 
successful in maintaining existing arrangements or entering into new ones, 
and even if we are, we may not realize the benefits of such relationships, 
and it could cause us to expend significant resources and give rise to 
substantial business risk with no assurance of financial return.

We are currently parties to license and collaboration agreements with 
a number of universities and pharmaceutical companies and expect 
to enter into additional agreements as part of our business strategy. 
Establishing strategic collaborations is difficult and time-consuming. Our 
discussions with potential collaborators may not lead to the establishment 
of collaborations on favorable terms, if at all. Potential collaborators 
may reject collaborations based upon their assessment of our financial, 
regulatory or intellectual property position. Even if we successfully 
establish new collaborations, these relationships may never result in the 
successful development or commercialization of therapeutic candidates 
or the generation of sales revenue. The success of our current and any 
future collaboration arrangements will depend heavily on the efforts and 
activities of our collaborators. Collaborations are subject to numerous 
risks, which may include risks that:

 — collaborators may have significant discretion in determining the efforts 

and resources that they will apply to collaborations;

 — collaborators may not pursue development and commercialization of 
the therapeutic candidates within our Internal Programs or may elect 
not to continue or renew development or commercialization programs 
based on clinical trial results, changes in their strategic focus due to their 
acquisition of competitive therapeutics or their internal development 
of competitive therapeutics, availability of funding or other external 
factors, such as a business combination that diverts resources or creates 
competing priorities;

 — collaborators may delay clinical trials, provide insufficient funding 

for a clinical trial program, stop a clinical trial, abandon a therapeutic 
candidate, repeat or conduct new clinical trials or require a new 
formulation of a therapeutic candidate for clinical testing;

 — collaborators could independently develop, or develop with third parties, 
therapeutics that compete directly or indirectly with our therapeutics or 
therapeutic candidates;

 — a collaborator with marketing, manufacturing and distribution rights 

to one or more therapeutics may not commit sufficient resources to or 
otherwise not perform satisfactorily in carrying out these activities;

 — we could grant exclusive rights to our collaborators that would prevent us 

from collaborating with others;

 — collaborators may not properly maintain or defend our intellectual 
property rights or may use our intellectual property or proprietary 
information in a way that gives rise to actual or threatened litigation that 
could jeopardize or invalidate our intellectual property or proprietary 
information or expose us to potential liability;

 — disputes may arise between us and a collaborator that cause the delay 

or termination of the research, development or commercialization of our 
current or future therapeutic candidates or that results in costly litigation 
or arbitration that diverts management attention and resources;

 — collaborations may be terminated, which may result in a need for 

additional capital to pursue further development or commercialization of 
the applicable current or future therapeutic candidates;

 — collaborators may own or co-own intellectual property covering 

therapeutics that result from our collaboration with them, and in such 
cases, we would not have the exclusive right to develop or commercialize 
such intellectual property;

 — disputes may arise with respect to the ownership of any intellectual 

property developed pursuant to our collaborations; and

 — a collaborator’s sales and marketing activities or other operations 
may not be in compliance with applicable laws resulting in civil or 
criminal proceedings.

Additionally, we may seek to enter into additional collaborations, joint 
ventures, licenses and other similar arrangements for the development 
or commercialization of the therapeutic candidates within our Internal 
Programs, due to capital costs required to develop or commercialize 
the therapeutic candidate or manufacturing constraints. We may not be 
successful in our efforts to establish such collaborations for the therapeutic 
candidates within our Internal Programs because our R&D pipeline may be 
insufficient, the therapeutic candidates within our Internal Programs may 
be deemed to be at too early of a stage of development for collaborative 
effort or third parties may not view the therapeutic candidates within our 
Internal Programs as having the requisite potential to demonstrate safety 
and efficacy or significant commercial opportunity, or collaborators may 

Risk Factor Annex continuedAdditional information206    PureTech Health plc   Annual Report and Accounts 2023

pursue existing or other development-stage therapeutics or alternative 
technologies in preference to those being developed in collaboration with 
us. In addition, we face significant competition in seeking appropriate 
strategic partners, and the negotiation process can be time consuming 
and complex. Further, any future collaboration agreements may restrict us 
from entering into additional agreements with potential collaborators. We 
cannot be certain that, following a strategic transaction or license, we will 
achieve an economic benefit that justifies such transaction.

Even if we are successful in our efforts to establish such collaborations, 
the terms that we agree upon may not be favorable to us, and we may not 
be able to maintain such collaborations if, for example, development or 
approval of a therapeutic candidate is delayed, the safety of a therapeutic 
candidate is questioned or sales of an approved therapeutic candidate 
are unsatisfactory. Additionally, if we enter into R&D collaborations during 
the early phases of therapeutic development, success will in part depend 
on the performance of research collaborators. We will not directly control 
the amount or timing of resources devoted by research collaborators to 
activities related to therapeutic candidates. Research collaborators may 
not commit sufficient resources to our R&D programs. If any research 
collaborator fails to commit sufficient resources, the preclinical or clinical 
development programs related to the collaboration could be delayed 
or terminated. 

In addition, any potential future collaborations may be terminable by 
our strategic partners, and we may not be able to adequately protect 
our rights under these agreements. Furthermore, strategic partners 
may negotiate for certain rights to control decisions regarding the 
development and commercialization of the therapeutic candidates within 
our Internal Programs, if approved, and may not conduct those activities 
in the same manner as we do. Any termination of collaborations we enter 
into in the future, or any delay in entering into collaborations related to 
the therapeutic candidates within our Internal Programs, could delay the 
development and commercialization of the therapeutic candidates within 
our Internal Programs and reduce their competitiveness if they reach 
the market, which could have a material adverse effect on our business, 
financial condition and results of operations.

We anticipate relying upon strategic collaborations for marketing and 
commercializing our existing therapeutic candidates, and we may rely even 
more on strategic collaborations for R&D of other therapeutic candidates 
or discoveries. We may sell therapeutic offerings through strategic 
partnerships with pharmaceutical and biotechnology companies. If we 
are unable to establish or manage such strategic collaborations on terms 
favorable to us in the future, our R&D efforts and potential to generate 
revenue may be limited. If we fail to make required milestone or royalty 
payments to collaborators or to observe other obligations in agreements 
with them, the collaborators may have the right to terminate or stop 
performance of those agreements.

Even if we successfully establish new collaborations, these relationships 
may never result in the successful development or commercialization of 
therapeutic candidates or the generation of sales revenue. To the extent 
that we enter into collaborative arrangements, the related therapeutic 
revenues are likely to be lower than if we directly marketed and sold 
therapeutics. Such collaborators may also consider alternative therapeutic 
candidates or technologies for similar indications that may be available to 
collaborate on and whether such a collaboration could be more attractive 
than the one with us for any future therapeutic candidate.

Management of our relationships with collaborators will require:

 — significant time and effort from our management team;

 — coordination of our marketing and R&D programs with the marketing and 

R&D priorities of our collaborators; and

 — effective allocation of our resources to multiple projects.

We rely on third parties to assist in conducting our clinical trials and some 
aspects of our research and preclinical testing, and those third parties 
may not perform satisfactorily, including failing to meet deadlines for the 
completion of such trials, research, or testing.

We currently rely and expect to continue to rely on third parties, such as 
CROs, clinical data management organizations, medical institutions, and 
clinical investigators, to conduct some aspects of research and preclinical 
testing and clinical trials. Any of these third parties may terminate their 
engagements with us or be unable to fulfill their contractual obligations. 
If any of our relationships with these third parties terminate, we may 
not be able to enter into arrangements with alternative third parties on 
commercially reasonable terms, or at all. If we need to enter into alternative 
arrangements, it would delay therapeutic development activities.

Further, although our reliance on these third parties for clinical 
development activities limits our control over these activities, we remain 
responsible for ensuring that each of our trials is conducted in accordance 
with the applicable protocol, legal and regulatory requirements and 

scientific standards. For example, notwithstanding the obligations of a 
CRO for a trial of one of the therapeutic candidates within our Internal 
Programs, we remain responsible for ensuring that each of our clinical 
trials is conducted in accordance with the general investigational plan 
and protocols for the trial. Moreover, the FDA and comparable foreign 
regulatory authorities require us to comply with requirements, commonly 
referred to as GCPs, for conducting, recording and reporting the results 
of clinical trials to assure that data and reported results are credible 
and accurate and that the rights, integrity and confidentiality of trial 
participants are protected. The FDA and comparable foreign regulatory 
authorities enforce these GCPs through periodic inspections of trial 
sponsors, principal investigators, clinical trial sites and IRBs. If we or our 
third-party contractors fail to comply with applicable GCPs, the clinical 
data generated in our clinical trials may be deemed unreliable and the FDA 
or comparable foreign regulatory authorities may require us to perform 
additional clinical trials before approving the therapeutic candidates within 
our Internal Programs, which would delay the regulatory approval process. 
We cannot be certain that, upon inspection, the FDA or comparable 
foreign regulatory authorities will determine that any of our clinical trials 
comply with GCPs. We are also required to register certain clinical trials 
and post the results of completed clinical trials on databases including 
a government-sponsored database, ClinicalTrials.gov, within certain 
timeframes. Failure to do so can result in fines, adverse publicity and civil 
and criminal sanctions.

Furthermore, the third parties conducting clinical trials on our behalf are 
not our employees, and except for remedies available to us under our 
agreements with such contractors, we cannot control whether or not they 
devote sufficient time, skill and resources to our ongoing development 
programs. These contractors may also have relationships with other 
commercial entities, including our competitors, for whom they may also 
be conducting clinical trials or other drug or medical device development 
activities, which could impede their ability to devote appropriate time to 
our clinical programs. If these third parties, including clinical investigators, 
do not successfully carry out their contractual duties, meet expected 
deadlines or conduct our clinical trials in accordance with regulatory 
requirements or our stated protocols, we may not be able to obtain, or 
may be delayed in obtaining, regulatory approvals for the therapeutic 
candidates within our Internal Programs. If that occurs, we will not be able 
to, or may be delayed in our efforts to, successfully commercialize the 
therapeutic candidates within our Internal Programs. In such an event, 
our financial results and the commercial prospects for any therapeutic 
candidates that we seek to develop could be harmed, our costs could 
increase and our ability to generate revenues could be delayed, impaired 
or foreclosed.

Our or our Founded Entities’ use of third parties to manufacture the 
therapeutic candidates within our Internal Programs or our Founded 
Entities’ therapeutic candidates and other therapeutic candidates that we 
or our Founded Entities may develop for preclinical studies and clinical 
trials may increase the risk that we or our Founded Entities will not have 
sufficient quantities of our or our Founded Entities’ therapeutic candidates, 
therapeutics, or necessary quantities of such materials on time or at an 
acceptable cost.

With respect to certain of the therapeutic candidates within our Internal 
Programs or our Founded Entities’ therapeutic candidates, we and certain 
of our Founded Entities do not currently have, nor do we plan to acquire, 
the infrastructure or capability internally to manufacture drug supplies 
for our ongoing clinical trials or any future clinical trials that we or our 
Founded Entities may conduct, and we and our Founded Entities lack the 
resources to manufacture any therapeutic candidates on a commercial 
scale. We rely, and expect to continue to rely, on third-party manufacturers 
to produce our and certain of our Founded Entities’ therapeutic candidates 
or other therapeutic candidates that we or our Founded Entities may 
identify for clinical trials, as well as for commercial manufacture if any 
therapeutic candidates receive marketing authorization. Any significant 
delay or discontinuity in the supply of a therapeutic candidate, or the 
raw material components thereof, for an ongoing clinical trial due to the 
need to replace a third-party manufacturer could considerably delay 
the clinical development and potential regulatory authorization of the 
therapeutic candidates within our Internal Programs or our Founded 
Entities’ therapeutic candidates, which could harm our business and results 
of operations.

We or our Founded Entities may be unable to identify and appropriately 
qualify third-party manufacturers or establish agreements with third-party 
manufacturers or do so on acceptable terms. Even if we or our Founded 
Entities are able to establish agreements with third-party manufacturers, 
reliance on third-party manufacturers entails additional risks, including:

 — reliance on the third party for sourcing of raw materials, components, and 
such other goods as may be required for execution of its manufacturing 
processes and the oversight by the third party of its suppliers;

Risk Factor Annex continuedAdditional informationPureTech Health plc   Annual Report and Accounts 2023    207  

 — reliance on the third party for regulatory compliance and quality 

assurance for the manufacturing activities each performs;

 — the possible breach of the manufacturing agreement by the third party;

 — the possible misappropriation of proprietary information, including trade 

secrets and know-how; and

 — the possible termination or non-renewal of the agreement by the 
third party at a time that is costly or inconvenient for us or our 
Founded Entities.

Furthermore, all of our CMOs are engaged with other companies to 
supply and/or manufacture materials or therapeutics for such companies, 
which exposes our manufacturers to regulatory risks for the production 
of such materials and therapeutics. The facilities used by our contract 
manufacturers to manufacture our drug, or medical device therapeutic 
candidates are subject to review by the FDA pursuant to inspections that 
will be conducted after we submit an NDA, BLA, PMA application or other 
marketing application to the FDA. We do not control the manufacturing 
process of, and are to some extent dependent on, our contract 
manufacturing partners for compliance with the regulatory requirements, 
known as cGMP requirements for manufacture of drug, biologic and 
device therapeutics. If our contract manufacturers cannot successfully 
manufacture material that conforms to our specifications and the strict 
regulatory requirements of the FDA or others, we will not be able to secure 
or maintain regulatory authorization for the therapeutic candidates within 
our Internal Programs or our Founded Entities’ therapeutic candidates 
manufactured at these manufacturing facilities. We are subject to similar 
requirements in foreign jurisdictions. In addition, we have no control over 
the ability of our contract manufacturers to maintain adequate quality 
control, quality assurance and qualified personnel. If the FDA or another 
comparable foreign regulatory agency does not approve these facilities for 
the manufacture of the therapeutic candidates within our Internal Programs 
or our Founded Entities’ therapeutic candidates or if any agency withdraws 
its approval in the future, we or our Founded Entities may need to find 
alternative manufacturing facilities, which would negatively impact our or 
our Founded Entities’ ability to develop, obtain regulatory authorization 
or certification for or market the therapeutic candidates within our Internal 
Programs or our Founded Entities’ therapeutic candidates, if cleared, 
certified or approved.

The therapeutic candidates within our Internal Programs or our Founded 
Entities’ therapeutic candidates may compete with other therapeutic 
candidates and marketed therapeutics for access to manufacturing 
facilities. Any performance failure on the part of our or our Founded 
Entities’ existing or future manufacturers could delay clinical development, 
marketing approval, certification or commercialization. Our and certain of 
our Founded Entities’ current and anticipated future dependence upon 
others for the manufacturing of the therapeutic candidates within our 
Internal Programs or our Founded Entities’ therapeutic candidates may 
adversely affect our future profit margins and our ability to commercialize 
any therapeutic candidates that receive marketing clearance or approval 
on a timely and competitive basis.

If the contract manufacturing facilities on which we and certain of our 
Founded Entities’ rely do not continue to meet regulatory requirements 
or are unable to meet our or our Founded Entities’ supply demands, our 
business will be harmed.

All entities involved in the preparation of therapeutic candidates for clinical 
trials or commercial sale, including our and certain of our Founded Entities’ 
existing CMOs for the therapeutic candidates within our Internal Programs 
or our Founded Entities’ therapeutic candidates, are subject to extensive 
regulation. Components of a finished drug or biologic therapeutic 
approved for commercial sale or used in late-stage clinical trials must be 
manufactured in accordance with cGMP, or similar regulatory requirements 
outside the United States. These regulations govern manufacturing 
processes and procedures, including recordkeeping, and the 
implementation and operation of quality systems to control and assure the 
quality of investigational therapeutics and therapeutics approved for sale. 
Similarly, medical devices must be manufactured in accordance with QSR 
and similar foreign requirements. Poor control of production processes can 
lead to the introduction of contaminants or to inadvertent changes in the 
properties or stability of Gelesis’ Plenity, Akili’s EndeavorRx, our Founded 
Entities’ other therapeutic candidates or the therapeutic candidates within 
our Internal Programs. Our or our Founded Entities’ failure, or the failure 
of third-party manufacturers, to comply with applicable regulations could 
result in sanctions being imposed on us or our Founded Entities, including 
clinical holds, fines, injunctions, civil penalties, delays, suspension or 
withdrawal of approvals or certification, license revocation, suspension of 
production, seizures or recalls of therapeutic candidates or marketed drugs 
or devices, operating restrictions and criminal prosecutions, any of which 
could significantly and adversely affect clinical or commercial supplies of 
the therapeutic candidates within our Internal Programs or our Founded 
Entities’ therapeutic candidates.

We and/or our CMOs must supply all necessary documentation, as 
applicable, in support of a marketing application, such as an NDA, BLA, 
PMA or MAA, on a timely basis and must adhere to regulations enforced by 
the FDA and other regulatory agencies through their facilities inspection 
program. Some of our CMOs have never produced a commercially 
approved pharmaceutical therapeutic and therefore have not obtained 
the requisite regulatory authority approvals to do so. The facilities and 
quality systems of some or all of our third-party contractors must pass a 
pre-approval inspection for compliance with the applicable regulations as 
a condition of regulatory approval of the therapeutic candidates within our 
Internal Programs or our Founded Entities’ therapeutic candidates or any 
of our other potential therapeutics. In addition, the regulatory authorities 
may, at any time, audit or inspect a manufacturing facility involved with the 
preparation of the therapeutic candidates within our Internal Programs 
or our Founded Entities’ therapeutic candidates or our other potential 
therapeutics or the associated quality systems for compliance with the 
regulations applicable to the activities being conducted. Although we 
oversee the CMOs, we cannot control the manufacturing process of, and 
are completely dependent on, our CMO partners for compliance with the 
regulatory requirements. If these facilities do not pass a pre-approval plant 
inspection, regulatory approval of the therapeutics may not be granted 
or may be substantially delayed until any violations are corrected to the 
satisfaction of the regulatory authority, if ever.

The regulatory authorities or notified bodies (when applicable) also may, 
at any time following clearance, certification or approval of a therapeutic 
for sale, audit the manufacturing facilities of our third-party contractors. If 
any such inspection or audit identifies a failure to comply with applicable 
regulations or if a violation of our therapeutic specifications or applicable 
regulations occurs independent of such an inspection or audit, we or the 
relevant regulatory authority may require remedial measures that may be 
costly and/or time consuming for us or a third party to implement, and that 
may include the temporary or permanent suspension of a clinical study or 
commercial sales or the temporary or permanent closure of a facility. Any 
such remedial measures imposed upon us or third parties with whom we 
contract could materially harm our business.

Additionally, if supply from one approved manufacturer is interrupted, an 
alternative manufacturer would need to be qualified. For drug and biologic 
therapeutics, as applicable, an NDA, BLA supplement or MAA variation, 
or equivalent foreign regulatory filing, is also required, which could result 
in further delay. Similarly, for medical devices, a new marketing application 
or supplement may be required. The regulatory agencies may also require 
additional studies if a new manufacturer is relied upon for commercial 
production. Switching manufacturers may involve substantial costs and is 
likely to result in a delay in our desired clinical and commercial timelines.

These factors could cause us or our Founded Entities to incur higher 
costs and could cause the delay or termination of clinical trials, regulatory 
submissions, required approvals, or commercialization of the therapeutic 
candidates within our Internal Programs or our Founded Entities’ 
therapeutic candidates. Furthermore, if our or our Founded Entities’ 
suppliers fail to meet contractual requirements and we or our Founded 
Entities are unable to secure one or more replacement suppliers capable of 
production at a substantially equivalent cost, our or our Founded Entities’ 
clinical trials may be delayed or we or our Founded Entities could lose 
potential revenue.

Risks Related to Our Intellectual Property

Risks Related to Our Intellectual Property Protection

If we or our Founded Entities are unable to obtain and maintain sufficient 
intellectual property protection for our or our Founded Entities’ existing 
therapeutic candidates or any other therapeutic candidates that we or 
they may identify, or if the scope of the intellectual property protection 
we or they currently have or obtain in the future is not sufficiently broad, 
our competitors could develop and commercialize therapeutic candidates 
similar or identical to ours, and our ability to successfully commercialize our 
existing therapeutic candidates and any other therapeutic candidates that 
we or they may pursue may be impaired.

As is the case with other pharmaceutical and biopharmaceutical 
companies, our success depends in large part on our ability to obtain and 
maintain protection of the intellectual property we may own solely and 
jointly with others, particularly patents, in the United States and other 
countries with respect to our Internal Programs or our Founded Entities’ 
therapeutic candidates and technology. We and our Founded Entities 
seek to protect our proprietary position by filing patent applications in the 
United States and abroad related to our and our Founded Entities’ existing 
therapeutic candidates, our various proprietary technologies, and any 
other therapeutic candidates or technologies that we or they may identify.

Risk Factor Annex continuedAdditional information208    PureTech Health plc   Annual Report and Accounts 2023

Obtaining, maintaining and enforcing pharmaceutical and 
biopharmaceutical patents is costly, time consuming and complex, and 
we may not be able to file or prosecute all necessary or desirable patent 
applications, or maintain, enforce or license patents that may issue from 
such patent applications, at a reasonable cost or in a timely manner. It 
is also possible that we could fail to identify patentable aspects of our 
R&D output before it is too late to obtain patent protection. Although 
we take reasonable measures, we have systems in place to remind us of 
filing and prosecution deadlines, and we employ outside firms and rely on 
outside counsel to monitor patent deadlines, we may miss or fail to meet 
a patent deadline, including in a foreign country, which could negatively 
impact our patent rights and harm our competitive position, business, and 
prospects. We may not have the right to control the preparation, filing and 
prosecution of patent applications, or to maintain the rights to patents 
licensed to third parties. Therefore, these patents and applications may not 
be prosecuted and enforced in a manner consistent with the best interests 
of our business.

The patent position of biotechnology and pharmaceutical companies 
generally is highly uncertain, involves complex legal, technological 
and factual questions and has in recent years been the subject of much 
litigation. The standards that the U.S. Patent and Trademark Office, or the 
USPTO, and its foreign counterparts use to grant patents are not always 
applied predictably or uniformly. In addition, the laws of foreign countries 
may not protect our rights to the same extent as the laws of the United 
States, or vice versa. There is no assurance that all potentially relevant 
prior art relating to our patents and patent applications has been found, 
which can prevent a patent from issuing from a pending application or 
later invalidate or narrow the scope of an issued patent. For example, 
publications of discoveries in the scientific literature often lag behind the 
actual discoveries, and patent applications in the United States and other 
jurisdictions are typically not published until 18 months after filing or, in 
some cases, not at all. Therefore, we cannot know with certainty whether 
we were the first to make the inventions claimed in our patents or pending 
patent applications, or that we were the first to file for patent protection of 
such inventions. As a result, the issuance, scope, validity, enforceability and 
commercial value of our patent rights are highly uncertain. Our pending 
and future patent applications may not result in patents being issued 
that protect our Internal Programs or our Founded Entities’ therapeutic 
candidates, in whole or in part, or which effectively prevent others from 
commercializing competitive therapeutic candidates. Even if our patent 
applications issue as patents, they may not issue in a form that will provide 
us with any meaningful protection, prevent competitors from competing 
with us or otherwise provide us with any competitive advantage. Our 
competitors may be able to circumvent our patents by developing similar 
or alternative therapeutic candidates in a non-infringing manner.

In addition, the issuance of a patent is not conclusive as to its inventorship, 
scope, validity or enforceability, and our patents may be challenged in the 
courts or patent offices in the United States and abroad. Such challenges 
may result in loss of exclusivity or freedom to operate or in patent claims 
being narrowed, invalidated or held unenforceable, in whole or in part, 
which could limit our ability to stop others from using or commercializing 
similar or identical therapeutic candidates to ours, or limit the duration of 
the patent protection of our Internal Programs or our Founded Entities’ 
therapeutic candidates. For example, we may be subject to a third-
party pre-issuance submission of prior art to the USPTO, or become 
involved in opposition, derivation, re-examination, inter partes review, 
post-grant review or interference proceedings challenging our owned or 
licensed patent rights. An adverse determination in any such submission, 
proceeding or litigation could reduce the scope of, or invalidate, our 
patent rights, allow third parties to commercialize our Internal Programs 
or our Founded Entities’ therapeutic candidates and compete directly 
with us, without payment to us, or result in our inability to manufacture 
or commercialize drugs without infringing third-party patent rights. In 
addition, if the breadth or strength of protection provided by our patents 
and patent applications is threatened, regardless of the outcome, it could 
dissuade companies from collaborating with us to license, develop or 
commercialize current or future therapeutic candidates.

Furthermore, our and our Founded Entities’ intellectual property rights 
may be subject to a reservation of rights by one or more third parties. 
We are party to a license agreement with New York University related to 
certain intellectual property underlying our LYT-200 therapeutic candidate, 
which is subject to certain rights of the government, including march-in 
rights, to such intellectual property due to the fact that the research was 
funded at least in part by the U.S. government. We are also party to other 
license agreements for intellectual property underlying certain of our 
therapeutic candidates and programs. Additionally, our Founded Entities 
Akili, Follica, Vedanta, Sonde and Vor, are party to license agreements 
with academic institutions pursuant to which such Founded Entities 
have in-licensed certain intellectual property underlying various of their 

therapeutic candidates. While these license agreements are exclusive, they 
contain provisions pursuant to which the government has certain rights, 
including march-in rights, to such patents and technologies due to the 
fact that the research was funded at least in part by the U.S. government. 
When new technologies are developed with government funding, the 
government generally obtains certain rights in any resulting patents, 
including a non-exclusive license authorizing the government to use the 
invention or to have others use the invention on its behalf. These rights may 
permit the government to disclose our information to third parties and to 
exercise march-in rights to use or allow third parties to use our technology. 
The government can exercise its march-in rights if it determines that 
action is necessary because we fail to achieve practical application of the 
government-funded technology, because action is necessary to alleviate 
health or safety needs, to meet requirements of federal regulations, or to 
give preference to U.S. industry. In addition, our rights in such inventions 
may be subject to certain requirements to manufacture therapeutics 
embodying such inventions in the United States. Any exercise by the 
government of such rights or by any third party of its reserved rights could 
harm our competitive position, business, financial condition, results of 
operations, and prospects.

If our or our Founded Entities’ trademarks and trade names are not 
adequately protected, then we may not be able to build name recognition 
in our markets of interest and our business may be adversely affected.

Our or our Founded Entities’ registered or unregistered trademarks or 
trade names may be challenged, infringed, circumvented or declared 
generic or determined to be infringing on other marks. We and our 
Founded Entities may not be able to protect our rights to these trademarks 
and trade names, which we need to build name recognition among 
potential collaborators or customers in our markets of interest. At times, 
competitors may adopt trade names or trademarks similar to ours, thereby 
impeding our ability to build brand identity and possibly leading to market 
confusion. In addition, there could be potential trade name or trademark 
infringement claims brought by owners of other trademarks or trademarks 
that incorporate variations of our registered or unregistered trademarks 
or trade names. Over the long term, if we and our Founded Entities are 
unable to establish name recognition based on our trademarks and trade 
names, then we may not be able to compete effectively and our business 
may be adversely affected. We and our Founded Entities may license 
our trademarks and trade names to third parties, such as distributors. 
Though these license agreements may provide guidelines for how our or 
our Founded Entities’ trademarks and trade names may be used, a breach 
of these agreements or misuse of our trademarks and tradenames by our 
licensees may jeopardize our rights in or diminish the goodwill associated 
with our trademarks and trade names. Our or our Founded Entities’ efforts 
to enforce or protect our proprietary rights related to trademarks, trade 
names, trade secrets, domain names, copyrights or other intellectual 
property may be ineffective and could result in substantial costs and 
diversion of resources and could adversely affect our competitive position, 
business, financial condition, results of operations and prospects.

We may not be able to protect our intellectual property rights 
throughout the world.

Filing, prosecuting and defending patents on the therapeutic candidates 
within our Internal Programs of our Founded Entities’ therapeutic 
Candidates in all countries throughout the world would be prohibitively 
expensive, and our intellectual property rights in some countries outside 
the United States can be less extensive than those in the United States. 
In addition, the laws of some foreign countries do not protect or enforce 
intellectual property rights to the same extent as federal and state laws in 
the United States. Consequently, we and our Founded Entities may not be 
able to prevent third parties from practicing our inventions in all countries 
outside the United States, or from selling or importing therapeutics made 
using our inventions in and into the United States or other jurisdictions. 
Competitors may use our and our Founded Entities’ technologies in 
jurisdictions where we have not obtained patent protection to develop 
their own therapeutics and may also export infringing therapeutics to 
territories where we have patent protection, but enforcement is not as 
strong as that in the United States. These therapeutics may compete 
with our or our Founded Entities’ therapeutics and our patents or other 
intellectual property rights may not be effective or sufficient to prevent 
them from competing.

Many companies have encountered significant problems in protecting and 
defending intellectual property rights in foreign jurisdictions. The legal 
systems of certain countries, particularly certain developing countries, do 
not favor the enforcement of patents, trade secrets, and other intellectual 
property protection, particularly those relating to biotechnology and 
pharmaceutical therapeutics, which could make it difficult for us to stop 
the infringement of our or our Founded Entities’ patents or marketing of 

Risk Factor Annex continuedAdditional informationPureTech Health plc   Annual Report and Accounts 2023    209  

competing therapeutics in violation of our proprietary rights generally. 
Proceedings to enforce our or our Founded Entities’ patent rights in 
foreign jurisdictions, whether or not successful, could result in substantial 
costs and divert our efforts and attention from other aspects of our 
business, could put our or our Founded Entities’ patents at risk of being 
invalidated or interpreted narrowly and our patent applications at risk 
of not issuing, and could provoke third parties to assert claims against 
us or our Founded Entities. We may not prevail in any lawsuits that we 
or our Founded Entities initiate and the damages or other remedies 
awarded, if any, may not be commercially meaningful. Accordingly, our 
efforts to enforce our intellectual property rights around the world may 
be inadequate to obtain a significant commercial advantage from the 
intellectual property that we develop or license.

In some jurisdictions including European Union countries, compulsory 
licensing laws compel patent owners to grant licenses to third parties. 
In addition, some countries limit the enforceability of patents against 
government agencies or government contractors. In these countries, the 
patent owner may have limited remedies, which could materially diminish 
the value of such patent. If we, our Founded Entities or any of our licensors 
are forced to grant a license to third parties under patents relevant to 
our or our Founded Entities’ business, or if we, our Founded Entities or 
our licensors are prevented from enforcing patent rights against third 
parties, our competitive position may be substantially impaired in such 
jurisdictions.

Our or our Founded Entities’ proprietary rights may not adequately protect 
our technologies and therapeutic candidates, and do not necessarily 
address all potential threats to our competitive advantage.

The degree of future protection afforded by our or our Founded Entities’ 
intellectual property rights is uncertain because intellectual property 
rights have limitations, and may not adequately protect our or our Founded 
Entities’ business, or permit us to maintain our competitive advantage. 
The following examples are illustrative:

 — others may be able to make therapeutics that are the same as or similar 

to the therapeutic candidates within our Internal Programs or our 
Founded Entities’ therapeutic candidates but that are not covered by 
the claims of the patents that we or our Founded Entities own or have 
exclusively licensed;

 — others, including inventors or developers of our or our Founded Entities’ 
owned or in-licensed patented technologies who may become involved 
with competitors, may independently develop similar technologies that 
function as alternatives or replacements for any of our or our Founded 
Entities’ technologies without infringing our intellectual property rights;

 — we, our Founded Entities or our licensors or our other collaboration 

partners might not have been the first to conceive and reduce to practice 
the inventions covered by the patents or patent applications that we or 
our Founded Entities own or license or will own or license;

 — we, our Founded Entities or our licensors or our other collaboration 

partners might not have been the first to file patent applications covering 
certain of the patents or patent applications that we or they own or have 
obtained a license, or will own or will have obtained a license;

 — we, our Founded Entities or our licensors may fail to meet obligations 
to the U.S. government with respect to in-licensed patents and patent 
applications funded by U.S. government grants, leading to the loss of 
patent rights;

 — it is possible that our or our Founded Entities’ pending patent 

applications will not result in issued patents;

 — it is possible that there are prior public disclosures that could invalidate 

our, our Founded Entities’ or our licensors’ patents;

 — issued patents that we or our Founded Entities own or exclusively 

license may not provide us with any competitive advantage, or may 
be held invalid or unenforceable, as a result of legal challenges by our 
competitors;

 — our or our Founded Entities’ competitors might conduct R&D activities 
in countries where we do not have patent rights, or in countries where 
R&D safe harbor laws exist, and then use the information learned from 
such activities to develop competitive therapeutics for sale in our major 
commercial markets;

 — ownership, validity or enforceability of our, our Founded Entities’ or our 
licensors’ patents or patent applications may be challenged by third 
parties; and

 — the patents of third parties or pending or future applications of third 

parties, if issued, may have an adverse effect on our business.

Risks Related to Our License Arrangements

The failure to maintain our licenses and realize their benefits may 
harm our business.

We have acquired and in-licensed certain of our technologies from third 
parties. We may in the future acquire, in-license or invest in additional 
technology that we believe would be beneficial to our business. We are 
subject to a number of risks associated with our acquisition, in-license or 
investment in technology, including the following:

 — diversion of financial and managerial resources from existing operations;

 — failure to successfully negotiate a proposed acquisition, in-license or 

investment in a timely manner and at a price or on terms and conditions 
favorable to us;

 — failure to successfully combine and integrate a potential acquisition into 

our existing business to fully realize the benefits of such acquisition;

 — the impact of regulatory reviews on a proposed acquisition, in-license or 

investment; and

 — the outcome of any legal proceedings that may be instituted with respect 

to the proposed acquisition, in-license or investment.

If we fail to properly evaluate potential acquisitions, in-licenses, 
investments or other transactions associated with the creation of new R&D 
programs or the maintenance of existing ones, we might not achieve the 
anticipated benefits of any such transaction, we might incur costs in excess 
of what we anticipate, and management resources and attention might be 
diverted from other necessary or valuable activities.

Our or our Founded Entities’ rights to develop and commercialize our 
Internal Programs or our Founded Entities’ therapeutic candidates are 
subject in part to the terms and conditions of licenses granted to us and 
our Founded Entities by others, and the patent protection, prosecution and 
enforcement for some of our Internal Programs or our Founded Entities’ 
therapeutic candidates may be dependent on our and our Founded 
Entities’ licensors.

We and our Founded Entities currently are reliant upon licenses of certain 
intellectual property rights and proprietary technologies from third 
parties that are important or necessary to the development of our and 
our Founded Entities’ proprietary technologies, including technologies 
related to our Internal Programs and our Founded Entities’ therapeutic 
candidates. These licenses, and other licenses we and they may enter into 
in the future, may not provide adequate rights to use such intellectual 
property and proprietary technologies in all relevant fields of use or in 
all territories in which we or our Founded Entities may wish to develop 
or commercialize technology and therapeutic candidates in the future. 
Licenses to additional third-party proprietary technology or intellectual 
property rights that may be required for our or our Founded Entities’ 
development programs may not be available in the future or may not 
be available on commercially reasonable terms. In that event, we or our 
Founded Entities may be required to expend significant time and resources 
to redesign our proprietary technology or therapeutic candidates or to 
develop or license replacement technology, which may not be feasible on 
a technical or commercial basis. If we and our Founded Entities are unable 
to do so, we may not be able to develop and commercialize technology 
and therapeutic candidates in fields of use and territories for which we 
are not granted rights pursuant to such licenses, which could harm our 
competitive position, business, financial condition, results of operations 
and prospects significantly.

In some circumstances, we and our Founded Entities may not have the right 
to control the preparation, filing and prosecution of patent applications, 
or to maintain and enforce the patents, covering technology that we or 
our Founded Entities license from third parties. In addition, some of our or 
our Founded Entities’ agreements with our licensors require us to obtain 
consent from the licensor before we can enforce patent rights, and our 
licensor may withhold such consent or may not provide it on a timely basis. 
Therefore, we cannot be certain that our licensors or collaborators will 
prosecute, maintain, enforce and defend such intellectual property rights 
in a manner consistent with the best interests of our business, including 
by taking reasonable measures to protect the confidentiality of know-how 
and trade secrets, or by paying all applicable prosecution and maintenance 
fees related to intellectual property registrations for any of our Internal 
Programs or our Founded Entities’ therapeutic candidates and proprietary 
technologies. We and our Founded Entities also cannot be certain that our 
licensors have drafted or prosecuted the patents and patent applications 
licensed to us in compliance with applicable laws and regulations, which 
may affect the validity and enforceability of such patents or any patents 
that may issue from such applications. This could cause us to lose rights 
in any applicable intellectual property that we in-license, and as a result 
our ability to develop and commercialize therapeutic candidates may be 
adversely affected and we may be unable to prevent competitors from 
making, using and selling competing therapeutics.

In addition, our or our Founded Entities’ licensors may own or control 
intellectual property that has not been licensed to us and, as a result, we 
may be subject to claims, regardless of their merit, that we are infringing 
or otherwise violating the licensor’s rights. In addition, while we cannot 
currently determine the amount of the royalty obligations we would be 
required to pay on sales of future therapeutics, if any, the amounts may 
be significant. The amount of our and our Founded Entities’ future royalty 
obligations will depend on the technology and intellectual property 
we and our Founded Entities use in therapeutic candidates that we 
successfully develop and commercialize, if any. Therefore, even if we or 
our Founded Entities successfully develop and commercialize therapeutic 
candidates, we may be unable to achieve or maintain profitability. In 
addition, we or our Founded Entities may seek to obtain additional licenses 
from our licensors and, in connection with obtaining such licenses, we 
may agree to amend our existing licenses in a manner that may be more 
favorable to the licensors, including by agreeing to terms that could 
enable third parties (potentially including our competitors) to receive 
licenses to a portion of the intellectual property rights that are subject 
to our or our Founded Entities’ existing licenses. Any of these events 
could have a material adverse effect on our or our Founded Entities’ 
competitive position, business, financial conditions, results of operations, 
and prospects.

If we or our Founded Entities fail to comply with our obligations in the 
agreements under which we license intellectual property rights from third 
parties or these agreements are terminated or we or our Founded Entities 
otherwise experience disruptions to our business relationships with our 
licensors, we could lose intellectual property rights that are important 
to our business.

We are party to various agreements that we depend on to develop our 
Internal Programs or our Founded Entities’ therapeutic candidates and 
various proprietary technologies, and our rights to use currently licensed 
intellectual property, or intellectual property to be licensed in the future, 
are or will be subject to the continuation of and our and our Founded 
Entities’ compliance with the terms of these agreements. For example, 
under certain of our and our Founded Entities’ license agreements we 
and our Founded Entities are required to use commercially reasonable 
efforts to develop and commercialize therapeutic candidates covered by 
the licensed intellectual property rights, maintain the licensed intellectual 
property rights, and achieve certain development milestones, each of 
which could result in termination in the event we or our Founded Entities 
fail to comply.

In spite of our efforts, our or our Founded Entities’ licensors might 
conclude that we have materially breached our obligations under such 
license agreements and might therefore terminate the license agreements, 
thereby removing or limiting our or our Founded Entities’ ability to 
develop and commercialize therapeutics and technology covered by these 
license agreements.

Moreover, disputes may arise regarding intellectual property subject to a 
licensing agreement, including:

 — the scope of rights granted under the license agreement and other 

interpretation-related issues;

 — the extent to which our Internal Programs or our Founded Entities’ 
therapeutic candidates, technology and processes infringe on 
intellectual property of the licensor that is not subject to the 
licensing agreement;

 — the sublicensing of patent and other rights under our or our Founded 

Entities’ collaborative development relationships;

 — our and our Founded Entities’ diligence obligations under the license 
agreement and what activities satisfy those diligence obligations;

 — the inventorship and ownership of inventions and know-how resulting 
from the joint creation or use of intellectual property by our and our 
Founded Entities’ licensors and us and our Founded Entities and our 
partners; and

 — the priority of invention of patented technology.

In addition, certain provisions in our and our Founded Entities’ license 
agreements may be susceptible to multiple interpretations. The resolution 
of any contract interpretation disagreement that may arise could narrow 
what we believe to be the scope of our rights to the relevant intellectual 
property or technology, or increase what we believe to be our financial 
or other obligations under the agreement, either of which could have a 
material adverse effect on our or our Founded Entities’ business, financial 
condition, results of operations and prospects. Moreover, if disputes over 
intellectual property that we or our Founded Entities have licensed prevent 
or impair our ability to maintain our current licensing arrangements on 
commercially acceptable terms, we may be unable to successfully develop 
and commercialize the affected therapeutic candidates, which could have 
a material adverse effect on our competitive position, business, financial 
conditions, results of operations and prospects.

Third-party claims of intellectual property infringement may prevent or 
delay our development and commercialization efforts.

Our commercial success depends in part on our avoiding infringement of 
the patents and proprietary rights of third parties. However, our research, 
development and commercialization activities may be subject to claims 
that we infringe or otherwise violate patents or other intellectual property 
rights owned or controlled by third parties. There is a substantial amount of 
litigation, both within and outside the United States, involving patent and 
other intellectual property rights in the biotechnology and pharmaceutical 
industries, including patent infringement lawsuits, interferences, 
derivation, oppositions, inter partes review and post-grant review before 
the USPTO, and corresponding foreign patent offices. Numerous U.S. and 
foreign issued patents and pending patent applications, which are owned 
by third parties, exist in the fields in which we are pursuing development 
candidates. Our competitors in both the United States and abroad, many 
of which have substantially greater resources and have made substantial 
investments in patent portfolios and competing technologies, may have 
applied for or obtained or may in the future apply for or obtain, patents 
that will prevent, limit or otherwise interfere with our ability to make, 
use and sell, if approved, the therapeutic candidates within our Internal 
Programs or our Founded Entities’ therapeutic candidates. In addition, 
many companies in the biotechnology and pharmaceutical industries have 
employed intellectual property litigation as a means to gain an advantage 
over their competitors. As the biotechnology and pharmaceutical 
industries expand and more patents are issued, and as we gain greater 
visibility and market exposure as a public company, the risk increases that 
our existing therapeutic candidates and any other therapeutic candidates 
that we or our Founded Entities may identify may be subject to claims of 
infringement of the patent rights of third parties.

There may be other third-party patents or patent applications with claims 
to materials, formulations, methods of manufacture or methods for 
treatment related to the use or manufacture of our or our Founded Entities’ 
existing therapeutic candidates and any other therapeutic candidates 
that we or they may identify. Because patent applications can take 
many years to issue, there may be currently pending patent applications 
which may later result in issued patents that our or our Founded Entities’ 
existing therapeutic candidates and any other therapeutic candidates 
that we or they may identify may infringe. In addition, third parties may 
obtain patents in the future and claim that use of our or our Founded 
Entities’ technologies infringes upon these patents. If any third-party 
patents were held by a court of competent jurisdiction to cover the 
manufacturing process of our or our Founded Entities’ existing therapeutic 
candidates and any other therapeutic candidates that we or they may 
identify, any molecules formed during the manufacturing process, or any 
final therapeutic itself, the holders of any such patents may be able to 
block our ability to commercialize such therapeutic candidate unless we 
obtained a license under the applicable patents, or until such patents 
expire. Additionally, pending patent applications that have been published 
can, subject to certain limitations, be later amended in a manner that 
could cover our Internal Programs or our Founded Entities’ therapeutic 
candidates. Furthermore, the scope of a patent claim is determined by 
an interpretation of the law, the written disclosure in a patent and the 
patent’s prosecution history and can involve other factors such as expert 
opinion. Our analysis of these issues, including interpreting the relevance 
or the scope of claims in a patent or a pending application, determining 
applicability of such claims to our proprietary technologies or therapeutic 
candidates, predicting whether a third party’s pending patent application 
will issue with claims of relevant scope, and determining the expiration 
date of any patent in the United States or abroad that we consider relevant 
may be incorrect, which may negatively impact our or our Founded Entities’ 
ability to develop and market the therapeutic candidates within our 
Internal Programs or our Founded Entities’ therapeutic candidates. We do 
not always conduct independent reviews of pending patent applications of 
and patents issued to third parties.

Similarly, if any third-party patents were held by a court of competent 
jurisdiction to cover aspects of our or our Founded Entities’ formulations, 
processes for manufacture or methods of use, including any combination 
therapies, the holders of any such patents may be able to block our or our 
Founded Entities’ ability to develop and commercialize the applicable 
therapeutic candidate unless we obtained a license or until such patent 
expires. In either case, such a license may not be available on commercially 
reasonable terms or at all, or it may be non-exclusive, which could result in 
our competitors gaining access to the same intellectual property.

Parties making claims against us or our Founded Entities may obtain 
injunctive or other equitable relief, which could effectively block our ability 
to further develop and commercialize our or our Founded Entities’ existing 
therapeutic candidates and any other therapeutic candidates that we may 
identify. Defense of these claims, regardless of their merit, would involve 
substantial litigation expense and would be a substantial diversion of 
management and employee resources from our business. In the event of 
a successful claim of infringement against us or our Founded Entities, we 

Risk Factor Annex continuedAdditional informationPureTech Health plc   Annual Report and Accounts 2023    211  

or our Founded Entities may have to pay substantial damages, including 
treble damages and attorneys’ fees for willful infringement, pay royalties, 
redesign our infringing therapeutics or obtain one or more licenses from 
third parties, which may be impossible or require substantial time and 
monetary expenditure.

Parties making claims against us or our Founded Entities may be able 
to sustain the costs of complex patent litigation more effectively than 
we can because they have substantially greater resources. Furthermore, 
because of the substantial amount of discovery required in connection 
with intellectual property litigation or administrative proceedings, there is 
a risk that some of our confidential information could be compromised by 
disclosure. In addition, any uncertainties resulting from the initiation and 
continuation of any litigation could have material adverse effect on our 
ability to raise additional funds or otherwise have a material adverse effect 
on our business, results of operations, financial condition and prospects.

Risks Related to Our Patents

Patent terms may be inadequate to protect our competitive position on 
therapeutic candidates for an adequate amount of time.

Patents have a limited lifespan. In the United States, if all maintenance fees 
are timely paid, the natural expiration of a patent is generally 20 years from 
its earliest U.S. non-provisional or international patent application filing 
date. Various extensions may be available, but the life of a patent, and 
the protection it affords, is limited. Even if patents covering our Internal 
Programs or our Founded Entities’ therapeutic candidates are obtained, 
once the patent life has expired, we or our Founded Entities may be 
open to competition from competitive therapeutics, including generics 
or biosimilars. Given the amount of time required for the development, 
testing and regulatory review of new therapeutic candidates, patents 
protecting such candidates might expire before or shortly after such 
candidates are commercialized. As a result, our or our Founded Entities’ 
owned and licensed patent portfolio may not provide us with sufficient 
rights to exclude others from commercializing therapeutics similar or 
identical to ours.

If we or our Founded Entities are not able to obtain patent term extension 
or non-patent exclusivity in the United States under the Hatch-Waxman 
Act and in foreign countries under similar legislation, thereby potentially 
extending the marketing exclusivity term of the therapeutic candidates 
within our Internal Programs or our Founded Entities’ therapeutic 
candidates, our business may be materially harmed.

Depending upon the timing, duration and specifics of FDA marketing 
approval of the therapeutic candidates within our Internal Programs or 
our Founded Entities’ therapeutic candidates, one or more of the U.S. 
patents covering each of such therapeutic candidates or the use thereof 
may be eligible for up to five years of patent term extension under the 
Hatch-Waxman Act. The Hatch-Waxman Act allows a maximum of one 
patent to be extended per new drug application, or NDA, for an FDA 
approved therapeutic as compensation for the patent term lost during the 
FDA regulatory review process. A patent term extension cannot extend 
the remaining term of a patent beyond a total of 14 years from the date of 
therapeutic approval and only those claims covering such approved drug 
therapeutic, a method for using it or a method for manufacturing it may be 
extended. Patent term extension also may be available in certain foreign 
countries upon regulatory approval of the therapeutic candidates within 
our Internal Programs or our Founded Entities’ therapeutic candidates. 
Nevertheless, we or our Founded Entities may not be granted patent term 
extension either in the United States or in any foreign country because of, 
for example, failing to exercise due diligence during the testing phase or 
regulatory review process, failing to apply within applicable deadlines, 
failing to apply prior to expiration of relevant patents or otherwise failing to 
satisfy applicable requirements. Moreover, the term of extension, as well as 
the scope of patent protection during any such extension, afforded by the 
governmental authority could be less than we request.

If we or our Founded Entities are unable to obtain patent term extension 
or restoration, or the term of any such extension is less than our request, 
the period during which we will have the right to exclusively market our 
therapeutic may be shortened and our competitors may obtain approval 
of competing therapeutics following our patent expiration sooner, and our 
revenue could be reduced, possibly materially.

Further, for certain of our and our Founded Entities’ licensed patents, we 
and our Founded Entities do not have the right to control prosecution, 
including filing with the USPTO, a petition for patent term extension 
under the Hatch-Waxman Act. Thus, if one of our or our Founded Entities’ 
licensed patents is eligible for patent term extension under the Hatch-
Waxman Act, we may not be able to control whether a petition to obtain a 
patent term extension is filed with, or whether a patent term extension is 
obtained from, the USPTO.

Also, there are detailed rules and requirements regarding the patents 
that may be submitted to the FDA for listing in the Approved Drug 
Products with Therapeutic Equivalence Evaluations, or the Orange Book. 
We or our Founded Entities may be unable to obtain patents covering 
the therapeutic candidates within our Internal Programs or our Founded 
Entities’ therapeutic candidates that contain one or more claims that 
satisfy the requirements for listing in the Orange Book. Even if we or our 
Founded Entities submit a patent for listing in the Orange Book, the FDA 
may decline to list the patent, or a manufacturer of generic drugs may 
challenge the listing. If or when one of the therapeutic candidates within 
our Internal Programs or our Founded Entities’ therapeutic candidates is 
approved and a patent covering that therapeutic candidate is not listed 
in the Orange Book, a manufacturer of generic drugs would not have to 
provide advance notice to us of any abbreviated new drug application, or 
ANDA, filed with the FDA to obtain permission to sell a generic version of 
such therapeutic candidate.

Issued patents covering our Internal Programs or our Founded Entities’ 
therapeutic candidates could be found invalid or unenforceable if 
challenged in courts or patent offices.

If we, our Founded Entities or one of our licensing partners initiated legal 
proceedings against a third party to enforce a patent covering one or more 
of our Internal Programs or our Founded Entities’ therapeutic candidates, 
the defendant could counterclaim that the patent covering the relevant 
therapeutic candidate is invalid and/or unenforceable. In patent litigation 
in the United States, defendant counterclaims alleging invalidity and/
or unenforceability are commonplace. Grounds for a validity challenge 
could be an alleged failure to meet any of several statutory requirements, 
including subject matter eligibility, novelty, nonobviousness, written 
description or enablement. Grounds for an unenforceability assertion 
could be an allegation that someone connected with prosecution of 
the patent withheld relevant information from the USPTO, or made a 
misleading statement, during prosecution. Third parties may also raise 
similar claims before administrative bodies in the United States or abroad, 
even outside the context of litigation. Such mechanisms include re-
examination, post grant review, and equivalent proceedings in foreign 
jurisdictions (e.g., opposition proceedings). Such proceedings could result 
in revocation or amendment to our or our Founded Entities’ patents in 
such a way that they no longer cover our Internal Programs or our Founded 
Entities’ therapeutic candidates. The outcome following legal assertions of 
invalidity and unenforceability is unpredictable. With respect to the validity 
question, for example, we cannot be certain that there is no invalidating 
prior art, of which we and the patent examiner were unaware during 
prosecution. If a defendant were to prevail on a legal assertion of invalidity 
and/or unenforceability, we would lose at least part, and perhaps all, of 
the patent protection on our Internal Programs or our Founded Entities’ 
therapeutic candidates. Such a loss of patent protection could have a 
material adverse impact on our business.

Changes in U.S. patent law could diminish the value of patents in general, 
thereby impairing our and our Founded Entities’ ability to protect 
our therapeutics.

Changes in either the patent laws or interpretation of the patent laws in 
the United States could increase the uncertainties and costs surrounding 
the prosecution of patent applications and the enforcement or defense 
of issued patents. Assuming that other requirements for patentability 
are met, prior to March 2013, in the United States, the first to invent the 
claimed invention was entitled to a patent, while outside the United States, 
the first to file a patent application was entitled to the patent. After March 
2013, under the Leahy-Smith America Invents Act, or the America Invents 
Act, enacted in September 2011, the United States transitioned to a first 
inventor to file system in which, assuming that other requirements for 
patentability are met, the first inventor to file a patent application will be 
entitled to the patent on an invention regardless of whether a third party 
was the first to invent the claimed invention. A third party that files a patent 
application in the USPTO after March 2013, but before us could therefore 
be awarded a patent covering an invention of ours even if we had made the 
invention before it was made by such third party. This will require us and 
our Founded Entities to be cognizant of the time from invention to filing 
of a patent application and be diligent in filing patent applications, but 
circumstances could prevent us from promptly filing patent applications 
on our inventions. Since patent applications in the United States and 
most other countries are confidential for a period of time after filing or 
until issuance, we cannot be certain that we, our Founded Entities or our 
licensors were the first to either (i) file any patent application related to 
our Internal Programs or our Founded Entities’ therapeutic candidates or 
(ii) invent any of the inventions claimed in our, our Founded Entities or our 
licensor’s patents or patent applications.

Risk Factor Annex continuedAdditional information212    PureTech Health plc   Annual Report and Accounts 2023

The America Invents Act also includes a number of significant changes 
that affect the way patent applications are prosecuted and also may 
affect patent litigation. These include allowing third party submission 
of prior art to the USPTO during patent prosecution and additional 
procedures to attack the validity of a patent by USPTO administered 
post-grant proceedings, including post-grant review, inter partes review, 
and derivation proceedings. Because of a lower evidentiary standard in 
USPTO proceedings compared to the evidentiary standard in U.S. federal 
courts necessary to invalidate a patent claim, a third party could potentially 
provide evidence in a USPTO proceeding sufficient for the USPTO to hold 
a claim invalid even though the same evidence would be insufficient to 
invalidate the claim if first presented in a district court action. Accordingly, 
a third party may attempt to use the USPTO procedures to invalidate our 
patent claims that would not have been invalidated if first challenged by the 
third party as a defendant in a district court action. Therefore, the America 
Invents Act and its implementation could increase the uncertainties and 
costs surrounding the prosecution of our or our Founded Entities’ owned 
or in-licensed patent applications and the enforcement or defense of our 
or our Founded Entities’ owned or in-licensed issued patents, all of which 
could have a material adverse effect on our competitive position, business, 
financial condition, results of operations, and prospects.

In addition, the patent positions of companies in the development and 
commercialization of pharmaceuticals are particularly uncertain. Recent 
U.S. Supreme Court and Federal Circuit rulings have narrowed the scope 
of patent protection available in certain circumstances and weakened the 
rights of patent owners in certain situations. This combination of events 
has created uncertainty with respect to the validity and enforceability of 
patents, once obtained. Depending on future actions by the U.S. Congress, 
the federal courts, and the USPTO, the laws and regulations governing 
patents could change in unpredictable ways that could have a material 
adverse effect on our existing patent portfolio and our ability to protect 
and enforce our intellectual property in the future.

Obtaining and maintaining our patent protection depends on compliance 
with various procedural, document submission, fee payment and other 
requirements imposed by governmental patent agencies, and our patent 
protection could be reduced or eliminated for non-compliance with 
these requirements.

Periodic maintenance fees, renewal fees, annuity fees and various other 
governmental fees on patents and/or applications will be due to be paid 
to the USPTO and various governmental patent agencies outside of the 
United States in several stages over the lifetime of the patents and/or 
applications. We and our Founded Entities have systems in place to remind 
us to pay these fees, and we and our Founded Entities employ outside 
firms and rely on outside counsel to pay these fees due to the USPTO 
and non-U.S. patent agencies. However, we and our Founded Entities 
cannot guarantee that our licensors have similar systems and procedures 
in place to pay such fees. In addition, the USPTO and various non-U.S. 
governmental patent agencies require compliance with a number of 
procedural, documentary, fee payment and other similar provisions during 
the patent application process. We employ reputable law firms and other 
professionals to help us comply, and in many cases, an inadvertent lapse 
can be cured by payment of a late fee or by other means in accordance 
with the applicable rules. However, there are situations in which non-
compliance can result in abandonment or lapse of the patent or patent 
application, resulting in partial or complete loss of patent rights in the 
relevant jurisdiction. In such an event, our competitors might be able to 
enter the market and this circumstance would have a material adverse 
effect on our business.

Risks Related to Confidentiality

If we are unable to protect the confidentiality of our trade secrets, the 
value of our technology could be materially adversely affected and our 
business would be harmed.

We and our Founded Entities consider proprietary trade secrets, 
confidential know-how and unpatented know-how to be important to 
our business. We and our Founded Entities may rely on trade secrets and 
confidential know-how to protect our technology, especially where patent 
protection is believed by us to be of limited value. However, trade secrets 
and confidential know-how are difficult to protect, and we have limited 
control over the protection of trade secrets and confidential know-how 
used by our licensors, collaborators and suppliers. Because we have relied 
in the past on third parties to manufacture the therapeutic candidates 
within our Internal Programs or our Founded Entities’ therapeutic 
candidates, because we may continue to do so in the future, and because 
we expect to collaborate with third parties on the development of our 
current therapeutic candidates and any future therapeutic candidates we 
develop, we may, at times, share trade secrets with them. We also conduct 
joint R&D programs that may require us to share trade secrets under 
the terms of our R&D partnerships or similar agreements. Under such 
circumstances, trade secrets and confidential know-how can be difficult to 
maintain as confidential.

We and our Founded Entities seek to protect our confidential proprietary 
information, in part, by confidentiality agreements and invention 
assignment agreements with our employees, consultants, scientific 
advisors, contractors and collaborators. These agreements are designed 
to protect our proprietary information. However, we cannot be certain 
that such agreements have been entered into with all relevant parties, 
and we cannot be certain that our and our Founded Entities’ trade secrets 
and other confidential proprietary information will not be disclosed 
or that competitors will not otherwise gain access to our trade secrets 
or independently develop substantially equivalent information and 
techniques. For example, any of these parties may breach the agreements 
and disclose proprietary information, including trade secrets, and we may 
not be able to obtain adequate remedies for such breaches. We and our 
Founded Entities also seek to preserve the integrity and confidentiality of 
our confidential proprietary information by maintaining physical security 
of our premises and physical and electronic security of our information 
technology systems, but it is possible that these security measures could 
be breached. If any of our or our Founded Entities’ confidential proprietary 
information were to be lawfully obtained or independently developed by 
a competitor, we or our Founded Entities would have no right to prevent 
such competitor from using that technology or information to compete 
with us, which could harm our competitive position.

Unauthorized parties may also attempt to copy or reverse engineer 
certain aspects of our or our Founded Entities’ therapeutics that we 
consider proprietary. We or our Founded Entities may not be able 
to obtain adequate remedies in the event of such unauthorized use. 
Enforcing a claim that a party illegally disclosed or misappropriated a 
trade secret can be difficult, expensive and time-consuming, and the 
outcome is unpredictable. In addition, some courts inside and outside 
the United States are less willing or unwilling to protect trade secrets. 
Trade secrets will also over time be disseminated within the industry 
through independent development, the publication of journal articles 
and the movement of personnel skilled in the art from company to 
company or academic to industry scientific positions. Though our or our 
Founded Entities’ agreements with third parties typically restrict the 
ability of our advisors, employees, collaborators, licensors, suppliers, 
third-party contractors and consultants to publish data potentially 
relating to our trade secrets, our agreements may contain certain limited 
publication rights. In addition, if any of our or our Founded Entities’ trade 
secrets were to be lawfully obtained or independently developed by 
a competitor, we would have no right to prevent such competitor from 
using that technology or information to compete with us, which could 
harm our competitive position. Despite employing the contractual and 
other security precautions described above, the need to share trade 
secrets increases the risk that such trade secrets become known by our 
competitors, are inadvertently incorporated into the technology of others, 
or are disclosed or used in violation of these agreements. If any of these 
events occurs or if we otherwise lose protection for our trade secrets, the 
value of such information may be greatly reduced and our competitive 
position, business, financial condition, results of operations, and prospects 
would be harmed.

We or our Founded Entities may be subject to claims that our employees, 
consultants or independent contractors have wrongfully used or 
disclosed confidential information of third parties or that our employees 
have wrongfully used or disclosed alleged trade secrets of their 
former employers.

As is common in the biotechnology and pharmaceutical industries, we and 
our Founded Entities employ individuals who were previously employed 
at universities or other biotechnology or pharmaceutical companies, 
including our competitors or potential competitors. Although we and 
our Founded Entities try to ensure that our employees, consultants and 
independent contractors do not use the proprietary information or know-
how of others in their work for us, we or our Founded Entities may be 
subject to claims that we or our employees, consultants or independent 
contractors have inadvertently or otherwise used or disclosed intellectual 
property, including trade secrets or other proprietary information, of 
any of our employee’s former employer or other third parties. Litigation 
may be necessary to defend against these claims. If we or our Founded 
Entities fail in defending any such claims, in addition to paying monetary 
damages, we may lose valuable intellectual property rights or personnel, 
which could adversely impact our business. Even if we or our Founded 
Entities are successful in defending against such claims, litigation could 
result in substantial costs and be a distraction to management and 
other employees.

monetary damages, we may lose valuable intellectual property rights, 
such as exclusive ownership of, or right to use, intellectual property 
that is important to our Internal Programs or our Founded Entities’ 
therapeutic candidates. Even if we are successful in defending against such 
claims, litigation could result in substantial costs and be a distraction to 
management and other employees. 

Any of the foregoing could have a material adverse effect on our 
competitive position, business, financial condition, results of operations 
and prospects.

Risks Related to the COVID-19 Pandemic or Future Public Health Crises

The COVID-19 pandemic has impacted, and any future global health crises 
may in the future impact, our business, including our clinical trials and 
preclinical studies, and may materially and adversely affect our business 
in the future.

Public health crises such as pandemics or other global emergencies could 
adversely impact our business and have a material adverse impact on our 
operations and financial condition and results. We have experienced as 
a result of COVID-19, and may in the future experience as a result of any 
future pandemic or global health crises, disruptions that severely impact 
our business, clinical trials and preclinical studies, including:

 — delays or difficulties in enrolling patients in our clinical trials;

 — delays or difficulties in clinical site initiation, including difficulties in 

recruiting clinical site investigators and clinical site staff;

 — delays or disruptions in non-clinical experiments due to unforeseen 

circumstances at contract research organizations, or CROs, and vendors 
along their supply chain;

 — increased rates of patients withdrawing from our clinical trials following 

enrollment as a result of contracting COVID-19, being forced to 
quarantine, or not accepting home health visits;

 — diversion of healthcare resources away from the conduct of clinical trials, 
including the diversion of hospitals serving as our clinical trial sites and 
hospital staff supporting the conduct of our clinical trials;

 — interruption of key clinical trial activities, such as clinical trial site data 
monitoring, due to limitations on travel imposed or recommended by 
federal or state governments, employers and others or interruption 
of clinical trial subject visits and study procedures (particularly any 
procedures that may be deemed non-essential), which may impact the 
integrity of subject data and clinical study endpoints;

 — interruption or delays in the operations of the FDA, comparable foreign 
regulatory agencies and notified bodies, which may impact review and 
approval or certification timelines;

 — interruption of, or delays in receiving, supplies of our therapeutic 

candidates from our contract manufacturing organizations due to staffing 
shortages, production slowdowns or stoppages and disruptions in 
delivery systems; and

 — limitations on employee resources that would otherwise be focused 
on the conduct of our preclinical studies and clinical trials, including 
because of sickness of employees or their families, the desire of 
employees to avoid contact with large groups of people, an increased 
reliance on working from home or mass transit disruptions.

The COVID-19 pandemic has had, and any future global health crises may 
have in the future, an unfavorable impact on global economic conditions, 
including a decrease in or loss of insurance coverage among individuals 
in the United States, an increase in unemployment, and other negative 
impacts. In addition, the trading prices for biopharmaceutical companies 
have been highly volatile as a result of recent extreme volatility in the 
global economy, including as a result of the COVID-19 pandemic. As a 
result, if we require any further capital we may face difficulties raising 
capital through sales of our ordinary shares or such sales may be on 
unfavorable terms. 

To the extent the COVID-19 pandemic adversely affects our business and 
financial results, it may also have the effect of heightening many of the 
other risks described in this “Risk Factors” section, such as those relating to 
our clinical development operations, the supply chain for our ongoing and 
planned clinical trials, and the availability of governmental and regulatory 
authorities to conduct inspections of our clinical trial sites, review materials 
submitted by us in support of our applications for regulatory approval and 
grant approval for our therapeutic candidates.

Risks Related to Challenges or Lawsuits Related to 
Intellectual Property

We may become involved in lawsuits to protect or enforce our or our 
Founded Entities’ patents or other intellectual property, which could be 
expensive, time consuming and unsuccessful.

Competitors may infringe our or our Founded Entities’ patents or other 
intellectual property. Our and our Founded Entities’ ability to enforce 
our patent or other intellectual property rights depends on our ability to 
detect infringement. It may be difficult to detect infringers who do not 
advertise the components or methods that are used in connection with 
their therapeutics and services. Moreover, it may be difficult or impossible 
to obtain evidence of infringement in a competitor’s or potential 
competitor’s therapeutic or service. We may not prevail in any lawsuits 
that we initiate and the damages or other remedies awarded if we were 
to prevail may not be commercially meaningful. If we were to initiate legal 
proceedings against a third party to enforce a patent covering one or more 
of our Internal Programs or our Founded Entities’ therapeutic candidates, 
the defendant could counterclaim that the patent covering our or our 
Founded Entities’ therapeutic candidate is invalid and/or unenforceable. 
In patent litigation in the United States, defendant counterclaims alleging 
invalidity and/or unenforceability are commonplace. Grounds for a validity 
challenge could be an alleged failure to meet any of several statutory 
requirements, including subject matter eligibility, novelty, nonobviousness, 
written description or enablement. Grounds for an unenforceability 
assertion could be an allegation that someone connected with prosecution 
of the patent withheld relevant information from the USPTO, or made a 
misleading statement, during prosecution. The outcome following legal 
assertions of invalidity and unenforceability is unpredictable. Interference 
or derivation proceedings provoked by third parties or brought by us or 
declared by the USPTO may be necessary to determine the priority of 
inventions with respect to our or our Founded Entities’ patents or patent 
applications. An unfavorable outcome could require us to cease using the 
related technology or to attempt to license rights to it from the prevailing 
party. Our business could be harmed if the prevailing party does not offer 
us a license on commercially reasonable terms or at all, or if a non-exclusive 
license is offered and our competitors gain access to the same technology. 
Our defense of litigation or interference or derivation proceedings may 
fail and, even if successful, may result in substantial costs and distract 
our management and other employees. In addition, the uncertainties 
associated with litigation could have a material adverse effect on our ability 
to raise the funds necessary to continue clinical trials, continue research 
programs, license necessary technology from third parties, or enter into 
development partnerships that would help us bring therapeutic candidates 
to market. Furthermore, because of the substantial amount of discovery 
required in connection with intellectual property litigation, there is a risk 
that some of our or our Founded Entities’ confidential information could 
be compromised by disclosure during this type of litigation. There could 
also be public announcements of the results of hearings, motions, or other 
interim proceedings or developments. If securities analysts or investors 
perceive these results to be negative, it could adversely impact the price of 
our ADSs. Furthermore, any of the foregoing could have a material adverse 
effect on our financial condition, results of operations, and prospects.

We and our Founded Entities may be subject to claims challenging the 
inventorship of our patents and other intellectual property.

Our and our Founded Entities’ agreements with employees and our 
personnel policies provide that any inventions conceived by an individual 
in the course of rendering services to us shall be our exclusive property. 
Although our policy is to have all such individuals complete these 
agreements, we may not obtain these agreements in all circumstances, 
and individuals with whom we have these agreements may not comply 
with their terms. The assignment of intellectual property may not 
be automatic upon the creation of an invention and despite such 
agreement, such inventions may become assigned to third parties. 
In the event of unauthorized use or disclosure of our trade secrets or 
proprietary information, these agreements, even if obtained, may not 
provide meaningful protection, particularly for our trade secrets or other 
confidential information.

We, our Founded Entities or our licensors may be subject to claims that 
former employees, collaborators or other third parties have an interest 
in our owned or in-licensed patents, trade secrets, or other intellectual 
property as an inventor or co-inventor. For example, we, our Founded 
Entities or our licensors may have inventorship disputes arising from 
conflicting obligations of employees, consultants or others who are 
involved in developing our Internal Programs or our Founded Entities’ 
therapeutic candidates. Litigation may be necessary to defend against 
these and other claims challenging inventorship of our, our Founded 
Entities’ or our licensors’ ownership of our owned or in-licensed patents, 
trade secrets or other intellectual property. If we, our Founded Entities 
or our licensors fail in defending any such claims, in addition to paying

Risks Related to Our Business and Industry

We attempt to distribute our scientific, execution and financing risks 
across a variety of therapeutic areas, indications, programs and modalities 
that are driven by our proven innovation and drug development 
strategy. However, our assessment of, and approach to, risk may not be 
comprehensive or effectively avoid delays or failures in one or more of our 
programs. Failures in one or more of our programs could adversely impact 
other programs and have a material adverse impact on our business, 
results of operations and ability to fund our business.

While we aim to distribute our scientific, execution and financing risks 
across programs, there may be foreseen and unforeseen risks across 
the therapeutic candidates within our Internal Programs and programs 
being developed by our Founded Entities in whole or in part. In addition, 
if any one or more of our clinical programs encounter safety, tolerability, 
or efficacy problems, developmental delays, regulatory issues, or other 
problems, our business could be significantly harmed. As our and certain 
of our Founded Entities’ therapeutic candidates progress through clinical 
development, we or others may determine that certain of our risk allocation 
decisions were incorrect or insufficient, that individual programs or our 
science in general has technology or biology risks that were unknown 
or underappreciated, or that we have allocated resources across our 
programs in such a way that did not maximize potential value creation. All 
of these risks may relate to our current and future programs sharing similar 
science and infrastructure, and in the event material decisions in any of 
these areas turn out to have been incorrect or under-optimized, we may 
experience a material adverse impact on our business and ability to fund 
our operations.

Our business is highly dependent on the clinical advancement of 
our programs and our success in identifying potential therapeutic 
candidates. Delay or failure to advance our programs could adversely 
impact our business.

Over time, our and our Founded Entities’ preclinical and clinical work led 
us to identify potential synergies across target therapeutic indications, 
generating a broad portfolio of therapeutic candidates across multiple 
programs. Even if a particular program is successful in any phase of 
development, such program could fail at a later phase of development, 
and other programs within the same therapeutic area may still fail at any 
phase of development including at phases where earlier programs in 
that therapeutic area were successful. This may be a result of technical 
challenges unique to that program or due to biology risk, which is 
unique to every program. As we progress our programs through clinical 
development, there may be new technical challenges that arise that cause 
an entire program or a group of programs within an area of focus to fail. 

Our future success depends on our ability to retain key employees, 
directors, consultants and advisors and to attract, retain and motivate 
qualified personnel.

Our ability to compete in the highly competitive biotechnology industry 
depends upon our ability to attract and retain highly qualified managerial, 
scientific and medical personnel. We are highly dependent on the 
management, R&D, clinical, financial and business development expertise 
of our executive officers, our directors, as well as the other members of our 
scientific and clinical teams, including Bharatt Chowrira, our chief executive 
officer, and Eric Elenko, our President. The loss of the services of any of 
our executive officers and other key personnel, and our inability to find 
suitable replacements could result in delays in therapeutic development 
and our financial condition and results of operations could be materially 
adversely affected.

Furthermore, each of our executive officers may terminate their 
employment with us at any time. Recruiting and retaining qualified 
scientific and clinical personnel and, if we progress the development of the 
therapeutic candidates within our Internal Programs toward scaling up for 
commercialization, sales and marketing personnel, will also be critical to 
our success. The loss of the services of our executive officers or other key 
employees could impede the achievement of research, development and 
commercialization objectives and seriously harm our ability to successfully 
implement our business strategy. Furthermore, replacing executive officers 
and key employees may be difficult and may take an extended period of 
time because of the limited number of individuals in our industry with the 
breadth of skills and experience required to successfully develop, gain 
regulatory approval for and commercialize the therapeutic candidates 
within our Internal Programs. Competition to hire qualified personnel 
in our industry is intense, and we may be unable to hire, train, retain or 
motivate these key personnel on acceptable terms given the competition 
among numerous pharmaceutical and biotechnology companies for similar 
personnel. Furthermore, to the extent we hire personnel from competitors, 
we may be subject to allegations that they have been improperly solicited 
or that they have divulged proprietary or other confidential information, or 
that their former employers own their research output. We also experience 
competition for the hiring of scientific and clinical personnel from 
universities and research institutions.

In addition, we rely on consultants and advisors, including scientific and 
clinical advisors, to assist us in formulating our research and development 
and commercialization strategy. Our consultants and advisors may be 
employed by employers other than us and may have commitments under 
consulting or advisory contracts with other entities that may limit their 
availability to us. If we are unable to continue to attract and retain high 
quality personnel, our ability to pursue our growth strategy will be limited.

We will need to expand our organization and we may experience 
difficulties in managing this growth, which could disrupt our operations.

As we mature, we expect to expand our full-time employee base and to 
hire more consultants and contractors. Our management may need to 
divert a disproportionate amount of its attention away from our day-to-day 
activities and devote a substantial amount of time toward managing these 
growth activities. We may not be able to effectively manage the expansion 
of our operations, which may result in weaknesses in our infrastructure, 
operational mistakes, loss of business opportunities, loss of employees and 
reduced productivity among remaining employees. Our expected growth 
could require significant capital expenditures and may divert financial 
resources from other projects, such as the development of additional 
therapeutic candidates. If our management is unable to effectively manage 
our growth, our expenses may increase more than expected, our ability 
to generate and/or grow revenues could be reduced, and we may not be 
able to implement our business strategy. Our future financial performance 
and our ability to commercialize therapeutic candidates and compete 
effectively will depend, in part, on our ability to effectively manage any 
future growth.

Because we are developing multiple programs and therapeutic candidates 
and are pursuing a variety of target indications and treatment modalities, 
we may expend our limited resources to pursue a particular therapeutic 
candidate and fail to capitalize on development opportunities or 
therapeutic candidates that may be more profitable or for which there 
is a greater likelihood of success.

Because we have limited financial and personnel resources, we may 
forgo or delay pursuit of opportunities with potential target indications 
or therapeutic candidates that later prove to have greater commercial 
potential than our current and planned development programs and 
therapeutic candidates. Our resource allocation decisions may cause 
us to fail to capitalize on viable commercial therapeutics or profitable 
market opportunities. Our spending on current and future research 
and development programs and other future therapeutic candidates 
for specific indications may not yield any commercially viable future 
therapeutic candidates. If we do not accurately evaluate the commercial 
potential or target market for a particular therapeutic candidate, we may be 
required to relinquish valuable rights to that therapeutic candidate through 
collaboration, licensing or other royalty arrangements in cases in which it 
would have been more advantageous for us to retain sole development 
and commercialization rights to such future therapeutic candidates.

Additionally, we may pursue additional in-licenses or acquisitions of 
development-stage assets or programs, which entails additional risk to 
us. Identifying, selecting and acquiring promising therapeutic candidates 
requires substantial technical, financial and human resources expertise. 
Efforts to do so may not result in the actual acquisition or license of a 
successful therapeutic candidate, potentially resulting in a diversion of 
our management’s time and the expenditure of our resources with no 
resulting benefit. For example, if we are unable to identify programs that 
ultimately result in approved therapeutics, we may spend material amounts 
of our capital and other resources evaluating, acquiring and developing 
therapeutics that ultimately do not provide a return on our investment.

Product liability lawsuits against us could cause us to incur substantial 
liabilities and could limit commercialization of any therapeutic candidates 
that we may develop.

We face an inherent risk of product liability exposure related to the 
testing of therapeutic candidates in human clinical trials and will face an 
even greater risk if we commercially sell any therapeutics that we may 
develop. If we cannot successfully defend ourselves against claims that 
the therapeutic candidates within our Internal Programs or medicines 
caused injuries, we could incur substantial liabilities. Regardless of merit or 
eventual outcome, liability claims may result in:

 — decreased demand for any therapeutic candidates or medicines that we 

may develop;

 — injury to our reputation and significant negative media attention;

 — withdrawal of clinical trial participants;

 — significant costs to defend the related litigation;

 — substantial monetary awards to trial participants or patients;

 — loss of revenue; and

 — the inability to commercialize the therapeutic candidates within our 

Internal Programs.

or data accurately or to disclose unauthorized activities. If we or our 
Founded Entities obtain FDA or comparable foreign regulatory authorities 
approval, or notified bodies certification, of the therapeutic candidates 
within our Internal Programs or our Founded Entities’ therapeutic 
candidates and begin commercializing those therapeutics in the United 
States and abroad, our potential exposure under such laws will increase 
significantly, and our costs associated with compliance with such laws are 
also likely to increase. In particular, research, sales, marketing, education 
and other business arrangements in the healthcare industry are subject to 
extensive laws designed to prevent fraud, kickbacks, self-dealing and other 
abusive practices. These laws and regulations may restrict or prohibit a 
wide range of pricing, discounting, educating, marketing and promotion, 
sales and commission, certain customer incentive programs and other 
business arrangements generally. Activities subject to these laws also 
involve the improper use of information obtained in the course of patient 
recruitment for clinical trials, which could result in regulatory sanctions and 
cause serious harm to our reputation. It is not always possible to identify 
and deter misconduct by employees and third parties, and the precautions 
we take to detect and prevent this activity may not be effective in 
controlling unknown or unmanaged risks or losses or in protecting us from 
governmental investigations or other actions or lawsuits stemming from a 
failure to be in compliance with such laws. If any such actions are instituted 
against us, and we are not successful in defending ourselves or asserting 
our rights, those actions could have a significant impact on our business, 
including the imposition of significant fines or other sanctions.

Employee litigation and unfavorable publicity could negatively affect our 
future business.

Our employees may, from time to time, bring lawsuits against us regarding 
injury, creating a hostile work place, discrimination, wage and hour 
disputes, sexual harassment, or other employment issues. In recent years, 
there has been an increase in the number of discrimination and harassment 
claims generally. Coupled with the expansion of social media platforms 
and similar devices that allow individuals access to a broad audience, 
these claims have had a significant negative impact on some businesses. 
Certain companies that have faced employment- or harassment-related 
lawsuits have had to terminate management or other key personnel, 
and have suffered reputational harm that has negatively impacted their 
business. If we were to face any employment-related claims, our business 
could be negatively affected.

If we fail to comply with environmental, health and safety laws and 
regulations, we could become subject to fines or penalties or incur costs 
that could harm our business.

We are subject to numerous environmental, health and safety laws and 
regulations, including those governing laboratory procedures and the 
handling, use, storage, treatment and disposal of hazardous materials 
and wastes. Our operations involve the use of hazardous and flammable 
materials, including chemicals and biological materials. Our operations 
also produce hazardous waste therapeutics. We generally contract with 
third parties for the disposal of these materials and wastes. We cannot 
eliminate the risk of contamination or injury from these materials. In the 
event of contamination or injury resulting from our use of hazardous 
materials, we could be held liable for any resulting damages, and any 
liability could exceed our resources. We also could incur significant costs 
associated with civil or criminal fines and penalties for failure to comply 
with such laws and regulations.

Although we maintain workers’ compensation insurance to cover us 
for costs and expenses we may incur due to injuries to our employees 
resulting from the use of hazardous materials, this insurance may not 
provide adequate coverage against potential liabilities. We do not 
maintain insurance for environmental liability or toxic tort claims that 
may be asserted against us in connection with our storage or disposal of 
biological, hazardous or radioactive materials.

In addition, we may incur substantial costs in order to comply with 
current or future environmental, health and safety laws and regulations. 
These current or future laws and regulations may impair our research, 
development or therapeutic efforts. Our failure to comply with these 
laws and regulations also may result in substantial fines, penalties or 
other sanctions.

Although we maintain product liability insurance, including coverage for 
clinical trials that we sponsor, it may not be adequate to cover all liabilities 
that we may incur. We anticipate that we will need to increase our insurance 
coverage as we commence additional clinical trials and if we successfully 
commercialize any therapeutic candidates. The market for insurance 
coverage is increasingly expensive, and the costs of insurance coverage 
will increase as our clinical programs increase in size. We may not be able 
to maintain insurance coverage at a reasonable cost or in an amount 
adequate to satisfy any liability that may arise.

Litigation against us could be costly and time-consuming to defend and 
could result in additional liabilities.

In March 2024, a complaint was filed against the company alleging breach 
of contract with respect to certain payments alleged to be owed to a 
previous employee of a company subsidiary based on purported terms of 
a contract between such individual and the company. We intend to defend 
ourselves vigorously though the ultimate outcome of this matter and the 
timing for resolution remains uncertain. No determination has been made 
that a loss, if any, arising from this matter is probable or that the amount of 
any such loss, or range of loss, is reasonably estimable. We may from time 
to time be subject to additional legal proceedings and claims that arise 
in the ordinary course of business or otherwise, such as claims brought 
by third parties in connection with commercial disputes and employment 
claims made by our current or former employees. Claims may also be 
asserted by or on behalf of a variety of other parties, including government 
agencies, patients, or stockholders. We could also be subject to securities 
class action litigation. In the past, securities class action litigation has often 
been brought against a company following a decline in the market price of 
its securities. This risk is especially relevant for us because biotechnology 
companies have experienced significant stock price volatility in recent 
years. If we face such litigation, it could result in substantial costs and 
a diversion of management’s attention and resources, which could 
harm our business.

Any litigation involving us may result in substantial costs, operationally 
restrict our business, and may divert management’s attention and 
resources, which may seriously harm our business, overall financial 
condition, and results of operations. Insurance may not cover existing 
or future claims, be sufficient to fully compensate us for one or more of 
such claims, or continue to be available on terms acceptable to us. A 
claim brought against us that is uninsured or underinsured could result in 
unanticipated costs, thereby adversely impacting our results of operations.

The increasing use of social media platforms presents new risks 
and challenges.

Social media is increasingly being used to communicate about our and 
our Founded Entities’ clinical development programs and the diseases 
our therapeutics are being developed to treat, and we intend to utilize 
appropriate social media in connection with our commercialization efforts 
following approval of the therapeutic candidates within our Internal 
Programs. Social media practices in the biopharmaceutical industry 
continue to evolve and regulations relating to such use are not always 
clear. This evolution creates uncertainty and risk of noncompliance with 
regulations applicable to our business. For example, patients may use 
social media channels to comment on their experience in an ongoing 
blinded clinical study or to report an alleged adverse event. When such 
disclosures occur, there is a risk that we fail to monitor and comply with 
applicable adverse event reporting obligations or we may not be able 
to defend our business or the public’s legitimate interests in the face 
of the political and market pressures generated by social media due to 
restrictions on what we may say about the therapeutic candidates within 
our Internal Programs. There is also a risk of inappropriate disclosure of 
sensitive information or negative or inaccurate posts or comments about 
us on any social networking website. If any of these events were to occur 
or we otherwise fail to comply with applicable regulations, we could incur 
liability, face regulatory actions or incur other harm to our business.

Our and our Founded Entities’ employees, independent contractors, 
consultants, commercial partners and vendors may engage in misconduct 
or other improper activities, including noncompliance with regulatory 
standards and requirements.

We are exposed to the risk of fraud, misconduct or other illegal activity 
by our employees, independent contractors, consultants, commercial 
partners and vendors as well as the employees, independent contractors, 
consultants, commercial partners and vendors of our Founded Entities. 
Misconduct by these parties could include intentional, reckless and 
negligent conduct that fails to: comply with the laws of the FDA and 
comparable foreign regulatory authorities; provide true, complete and 
accurate information to the FDA and comparable foreign regulatory 
authorities; comply with manufacturing standards we have established; 
comply with healthcare fraud and abuse laws in the United States and 
similar foreign fraudulent misconduct laws; or report financial information

Cyberattacks or other failures in our telecommunications or information 
technology systems, or those of our collaborators, contract research 
organizations, third-party logistics providers, distributors or other 
contractors or consultants, could result in information theft, data 
corruption and significant disruption of our business operations.

We collect and maintain information in digital form that is necessary to 
conduct our business, and we are increasingly dependent on information 
technology, or IT, systems and infrastructure to operate our business. In 
the ordinary course of our business, we collect, store, and transmit large 
amounts of confidential information, including intellectual property, 
proprietary business information, clinical trial data, and personal 
information (collectively, “Confidential Information”) of clinical trial 
participants, employees, and contractors. It is critical that we do so in 
a secure manner to maintain the confidentiality and integrity of such 
Confidential Information. 

As use of digital technologies has increased, cyber incidents, including 
third parties gaining access to employee accounts using stolen or 
inferred credentials, computer malware (e.g., ransomware), viruses, 
misconfigurations, “bugs” or other vulnerabilities, malicious code 
spamming, phishing attacks or other means, and deliberate attacks and 
attempts to gain unauthorized access to computer systems and networks, 
have increased in frequency and sophistication. These threats pose a risk 
to the security of our, our collaborators’, our CROs’, third-party logistics 
providers’, distributors’ and other contractors’ and consultants’ systems 
and networks, and the confidentiality, availability and integrity of our 
data. There can be no assurance that we will be successful in preventing 
cyberattacks or successfully mitigating their effects. Similarly, there can be 
no assurance that our collaborators, CROs, third-party logistics providers, 
distributors and other contractors and consultants will be successful in 
protecting our clinical and other data that is stored on their systems. 

We and certain of our service providers are from time to time subject to 
cyberattacks and security incident. Although to our knowledge we have 
not experienced any significant system failure, accident or material security 
breach to date, if such an event were to occur and cause interruptions in 
our operations, it could result in a material disruption of development 
programs and business operations.

Any cyber attack, data breach or destruction or loss of data could result in 
a violation of applicable U.S. and international privacy, data protection and 
other laws, and subject us to litigation and governmental investigations 
and proceedings by federal, state and local regulatory entities in the 
United States and by international regulatory entities, resulting in exposure 
to material civil and/or criminal liability. A security incident could also 
expose us to risks and could cause management distraction and the 
obligation to devote significant financial and other resources to mitigate 
such problems, which would increase our future information security costs, 
including through organizational changes, deploying additional personnel, 
reinforcing administrative, physical and technical safeguards, further 
training of employees, changing third-party vendor control practices, and 
engaging third-party subject matter experts and consultants and reduce 
the demand for our technology and services. Any security compromise 
affecting us, our collaborators, CROs, third-party logistics providers, 
distributors, and other contractors and consultants, or our industry, 
whether real or perceived, could harm our reputation, erode confidence in 
the effectiveness of our security measures and lead to regulatory scrutiny.

Further, our general liability insurance and corporate risk program may 
not cover all potential claims to which we are exposed and may not be 
adequate to indemnify us for all liability that maybe imposed; and could 
have a material adverse effect on our business and prospects. For example, 
the loss of clinical trial data from completed or ongoing clinical trials for 
any of the therapeutic candidates within our Internal Programs or our 
Founded Entities’ therapeutic candidates could result in delays in our 
development and regulatory approval efforts and significantly increase our 
costs to recover or reproduce the data.

The increasing focus on environmental sustainability and social initiatives 
could increase our costs, harm our reputation and adversely impact our 
financial results.

There has been increasing public focus by investors, patients, 
environmental activists, the media and governmental and 
nongovernmental organizations on a variety of environmental, social 
and other sustainability matters. We may experience pressure to make 
commitments relating to sustainability matters that affect us, including the 
design and implementation of specific risk mitigation strategic initiatives 
relating to sustainability. Expectations regarding the management of 
environmental, social and governance, or ESG, initiatives continues 
to evolve rapidly. While we may from time to time engage in various 
initiatives (including but not limited to voluntary disclosures, policies, or 
goals) to improve our ESG profile or respond to stakeholder expectations, 
we cannot guarantee that these initiatives will have the desired effect. 
If we are not effective in addressing environmental, social and other 

sustainability matters affecting our business, or setting and meeting 
relevant sustainability goals, our reputation and financial results may suffer. 
In addition, even if we are effective at addressing such concerns, we may 
experience increased costs as a result of executing upon our sustainability 
goals that may not be offset by any benefit to our reputation, which could 
have an adverse impact on our business and financial condition.

In addition, this emphasis on environmental, social and other sustainability 
matters has resulted and may result in the adoption of new laws and 
regulations, including new reporting requirements. If we fail to comply 
with new laws, regulations or reporting requirements, our reputation and 
business could be materially and adversely impacted.

We may acquire businesses, or therapeutics or therapeutic candidates, or 
form strategic alliances, in the future, and we may not realize the benefits 
of such acquisitions. 

We acquire or in-license businesses or therapeutics from other companies 
or create joint ventures with third parties that we believe will complement 
or augment our existing business. If we acquire businesses with promising 
markets or technologies, we may not be able to realize the benefit of 
acquiring such businesses if we are unable to successfully integrate them 
with our existing operations and company culture or retain key personnel 
from the acquired company. We may encounter numerous difficulties 
in developing, manufacturing and marketing any new therapeutics or 
therapeutic candidates resulting from a strategic alliance or acquisition 
that delay or prevent us from realizing their expected benefits or 
enhancing our business. We cannot assure you that, following any such 
acquisition or license, we will achieve the expected synergies to justify 
the transaction. Failure to successfully identify, complete, manage and 
integrate acquisitions could materially and adversely affect our business, 
financial condition and results of operations and could cause the price of 
our securities to decline.

Changes in funding for the FDA, the SEC and other government agencies 
could hinder their ability to hire and retain key leadership and other 
personnel, prevent new therapeutics and services from being developed 
or commercialized in a timely manner or otherwise prevent those agencies 
from performing normal functions on which the operation of our business 
may rely, which could negatively impact our business.

The ability of the FDA, foreign regulatory authorities and notified bodies 
to review and approve or certify new therapeutics or take action with 
respect to other regulatory matters can be affected by a variety of factors, 
including government budget and funding levels, ability to hire and retain 
key personnel and accept payment of user fees, and statutory, regulatory, 
and policy changes. In addition, government funding of the SEC and other 
government agencies on which our operations may rely, including those 
that fund research and development activities is subject to the political 
process, which is inherently fluid and unpredictable. The priorities of the 
FDA and foreign regulatory authorities may also influence the ability of 
the FDA and foreign regulatory authorities to take action on regulatory 
matters, for example the FDA’s and foreign regulatory authorities’ budget 
and funding levels and ability to hire and retain key personnel.

Disruptions at the FDA and foreign regulatory authorities may also slow 
the time necessary for new drugs to be reviewed and/or approved, or for 
other actions to be taken, by relevant government agencies, which would 
adversely affect our business. For example, over the last several years, 
the U.S. government has shut down several times and certain regulatory 
agencies, such as the FDA and the SEC, have had to furlough critical FDA, 
SEC and other government employees and stop critical activities. If a 
prolonged government shutdown occurs, it could significantly impact the 
ability of the FDA to timely review and process our regulatory submissions, 
which could have a material adverse effect on our business. Similarly, 
a prolonged government shutdown could prevent the timely review of 
our patent applications by the USPTO, which could delay the issuance of 
any U.S. patents to which we might otherwise be entitled. Further, in our 
operations as a public company, future government shutdowns could 
impact our ability to access the public markets and obtain necessary 
capital in order to properly capitalize and continue our operations.

Separately, in response to the global COVID-19 pandemic, the FDA 
postponed most inspections of domestic and foreign manufacturing 
facilities at various points. Even though the FDA has since resumed 
standard inspection operations of domestic facilities where feasible, future 
shutdown as a result of COVID-19 or any other public health crises may 
lead to inspectional or administrative delays. If a prolonged government 
shutdown or other disruption occurs, it could significantly impact the ability 
of the FDA to timely review and process our regulatory submissions, which 
could have a material adverse effect on our business. Future shutdowns or 
other disruptions could also affect other government agencies such as the 
SEC, which may also impact our business by delaying review of our public 
filings, to the extent such review is necessary, and our ability to access the 
public markets.

Furthermore, in the EU, notified bodies must be officially designated 
to certify products and services in accordance with the EU Medical 
Devices Regulation. Despite a recent increase in designations, the 
current number of notified bodies designated under the new Regulation 
remains significantly lower than the number of notified bodies designated 
under the previous regime. The current designated notified bodies 
are therefore facing a backlog of requests as a consequence of which 
review times have lengthened. This situation may impact the way we are 
conducting our business in the EU and the EEA and the ability of our 
notified body to timely review and process our regulatory submissions and 
perform its audits.

We or the third parties upon whom we depend may be adversely affected 
by a natural disaster and our business continuity and disaster recovery 
plans may not adequately protect us from a serious disaster.

Natural disasters could severely disrupt our operations, and have a 
material adverse effect on our business, results of operations, financial 
condition and prospects. If a natural disaster, power outage or other 
event occurred that prevented us from using all or a significant portion 
of our headquarters, that damaged critical infrastructure, such as the 
manufacturing facilities of our third-party CMOs, or that otherwise 
disrupted operations, it may be difficult or, in certain cases, impossible 
for us to continue our business for a substantial period of time. The 
disaster recovery and business continuity plans we have in place currently 
are limited and are unlikely to prove adequate in the event of a serious 
disaster or similar event. We may incur substantial expenses as a result of 
the limited nature of our disaster recovery and business continuity plans, 
which, could have a material adverse effect on our business, financial 
condition, results of operations and prospects.

We will continue to incur increased costs as a result of operating as a U.S.-
listed public company, and our management will be required to devote 
substantial time to new compliance initiatives.

As a U.S. public company, and particularly now that we are no longer an 
emerging growth company, we have incurred and will continue to incur 
significant legal, accounting and other expenses that we did not incur as a 
public company listed only on the LSE. In addition, the Sarbanes-Oxley Act 
of 2002, or the Sarbanes-Oxley Act, and rules subsequently implemented 
by the SEC and Nasdaq have imposed various requirements on public 
companies, including establishment and maintenance of effective 
disclosure and financial controls and corporate governance practices. 
Our management and other personnel continue to devote a substantial 
amount of time to these compliance initiatives. Moreover, these rules and 
regulations will increase our legal and financial compliance costs and will 
make some activities more time-consuming and costly. For example, we 
expect that these rules and regulations may make it more difficult and 
more expensive for us to obtain director and officer liability insurance.

We continue to evaluate these rules and regulations and cannot predict 
or estimate the amount of additional costs we may incur or the timing 
of such costs. These rules and regulations are often subject to varying 
interpretations, in many cases due to their lack of specificity, and, as a 
result, their application in practice may evolve over time as new guidance 
is provided by regulatory and governing bodies. This could result in 
continuing uncertainty regarding compliance matters and higher costs 
necessitated by ongoing revisions to disclosure and governance practices.

Risks Related to Our International Operations

Our international operations may expose us to business, regulatory, 
political, operational, financial, pricing and reimbursement and economic 
risks associated with doing business outside of the United States.

As a company based in the United Kingdom, our business is subject to 
risks associated with being organized outside of the United States. While 
the majority of our operations are in the United States and our functional 
currency is the U.S. dollar, our future results could be harmed by a variety 
of international factors, including:

 — economic weakness, including inflation, or political instability in 

particular non-U.S. economies and markets;

 — differing and changing regulatory requirements;

 — difficulties in compliance with different, complex and changing laws, 

regulations and court systems of multiple jurisdictions and compliance 
with a wide variety of foreign laws, treaties and regulations;

 — changes in a specific country’s or region’s political or economic 

environment, including, but not limited to, the implications of one or 
more of the following occurring the decision of the United Kingdom:

 — future activities subject to the terms of the Trade and Cooperation 
Agreement between the United Kingdom and the European Union 
effective May 1, 2021, which has not impacted our results to-date;

 — a second referendum on Scottish independence from the United 

Kingdom; and/or

 — a snap general election; and

 — negative consequences from changes in tax laws.

In addition, our business strategy incorporates potential international 
expansion to target patient populations outside the United States. If we or 
our Founded Entities receive regulatory approval for and commercialize 
any of the therapeutic candidates within our Internal Programs or our 
Founded Entities’ therapeutic candidates in patient populations outside 
the United States, we may hire sales representatives and conduct physician 
and patient association outreach activities outside of the United States. 
Doing business internationally involves a number of risks, including, but 
not limited to:

 — multiple, conflicting, and changing laws and regulations such as privacy 
regulations, tax laws, export and import restrictions, employment laws, 
regulatory requirements, and other governmental approvals, permits, 
and licenses;

 — failure by us to obtain and maintain regulatory approvals for the use of 

our therapeutics in various countries;

 — additional potentially relevant third-party patent rights;

 — complexities and difficulties in obtaining protection and enforcing our 

intellectual property;

 — difficulties in staffing and managing foreign operations;

 — complexities associated with managing multiple payor reimbursement 

regimes, government payors, or patient self-pay systems;

 — limits in our ability to penetrate international markets;

 — financial risks, such as longer payment cycles, difficulty collecting 

accounts receivable, the impact of local and regional financial crises 
on demand and payment for our therapeutics, and exposure to foreign 
currency exchange rate fluctuations;

 — natural disasters, political and economic instability, including wars, 

terrorism, and political unrest, outbreak of disease, boycotts, curtailment 
of trade, and other business restrictions;

 — certain expenses including, among others, expenses for travel, 

translation, and insurance; and

 — regulatory and compliance risks that relate to maintaining accurate 

information and control over sales and activities that may fall within the 
purview of the U.S. Foreign Corrupt Practices Act of 1977, as amended, or 
the FCPA, its books and records provisions, or its anti-bribery provisions.

Any of these factors could significantly harm our potential international 
expansion and operations and, consequently, our results of operations.

Unfavorable global economic conditions could adversely affect our 
business, financial condition or results of operations.

Our ability to invest in and expand our business and meet our financial 
obligations, to attract and retain third-party contractors and collaboration 
partners and to raise additional capital depends on our operating and 
financial performance, which, in turn, is subject to numerous factors, 
including the prevailing economic and political conditions and financial, 
business and other factors beyond our control, such as the rate of 
unemployment, the number of uninsured persons in the United States, 
political influences and inflationary pressures. For example, an overall 
decrease in or loss of insurance coverage among individuals in the United 
States as a result of unemployment, underemployment or the repeal of 
certain provisions of the ACA, may decrease the demand for healthcare 
services and pharmaceuticals. If fewer patients are seeking medical care 
because they do not have insurance coverage, we and our Founded 
Entities may experience difficulties in any eventual commercialization of 
the therapeutic candidates within our Internal Programs or our Founded 
Entities’ therapeutic candidates and our business, results of operations, 
financial condition and cash flows could be adversely affected.

In addition, our results of operations could be adversely affected by 
general conditions in the global economy and in the global financial 
markets upon which pharmaceutical and biopharmaceutical companies 
such as us are dependent for sources of capital. In the past, global financial 
crises have caused extreme volatility and disruptions in the capital 
and credit markets. A severe or prolonged economic downturn could 
result in a variety of risks to our business, including a reduced ability to 
raise additional capital when needed on acceptable terms, if at all, and 
weakened demand for the therapeutic candidates within our Internal 
Programs. A weak or declining economy could also strain our suppliers, 
possibly resulting in supply disruption. Any of the foregoing could harm 
our business and we cannot anticipate all of the ways in which the current 
economic climate and financial market conditions could adversely impact 
our business. Additionally, we maintain the majority of our cash and 

Risk Factor Annex continuedAdditional information218    PureTech Health plc   Annual Report and Accounts 2023

cash equivalents in accounts with major U.S. and multi-national financial 
institutions, and our deposits at certain of these institutions exceed insured 
limits. Market conditions can impact the viability of these institutions. In 
the event of failure of any of the financial institutions where we maintain 
our cash and cash equivalents, there can be no assurance that we would 
be able to access uninsured funds in a timely manner or at all. Any inability 
to access or delay in accessing these funds could adversely affect our 
business and financial position.

We are subject to the U.K. Bribery Act 2010, or the Bribery Act, the U.S. 
Foreign Corrupt Practices Act of 1977 (as amended) (“FCPA”) and other 
anti-corruption laws, as well as export control laws, import and customs 
laws, trade and economic sanctions laws and other laws governing 
our operations.

Our operations are subject to anti-corruption laws, including the Bribery 
Act, the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. 
§201, the U.S. Travel Act, and other anti-corruption laws that apply in 
countries where we do business. These laws generally prohibit us and 
our employees and intermediaries acting on our behalf from corruptly 
authorizing, promising, offering, or providing, directly or indirectly, 
anything else of value, to government officials or other persons to obtain 
or retain business or gain some other business advantage. The Bribery Act 
also prohibits: (i) “commercial” bribery of private parties, in addition to 
bribery involving domestic or foreign officials; (ii) the acceptance of bribes, 
as well as the giving of bribes, and (iii) “facilitation payments”, meaning 
generally low level payments designed to secure or expedite routine 
governmental actions or other conduct to which persons are already under 
obligations to perform. The Bribery Act also creates an offence applicable 
corporate entities for failure to prevent bribery by our employees, officers, 
directors and other third parties acting on our behalf, to which the only 
defence is to maintain “adequate procedures” designed to prevent such 
acts of bribery. 

In the future, we and our strategic partners may operate in jurisdictions that 
pose a heightened risk of potential Bribery Act or FCPA violations, and we 
may participate in collaborations and relationships with third parties whose 
conduct could potentially subject us to liability under the Bribery Act, 
FCPA or other anti-corruption laws, even if we do not explicitly authorize 
or have actual knowledge of such activities. In addition, we cannot predict 
the nature, scope or effect of future regulatory requirements to which our 
international operations might be subject or the manner in which existing 
laws might be administered or interpreted.

We are also subject to other laws and regulations governing our 
international operations, including regulations administered by the 
governments of the United Kingdom and the United States, and authorities 
in the European Union and its member states, including applicable export 
control regulations, economic sanctions and embargoes on certain 
countries, regions, and persons, import and customs requirements and 
currency exchange regulations, collectively referred to as the Trade Control 
laws. Compliance with Trade Control Laws regarding the import and export 
of our products may create delays in the introduction of our products 
in international markets, and, in some cases, prevent the export of our 
products to some countries altogether.

We have policies and procedures designed to promote compliance 
with anti-corruption laws and Trade Control laws. However, there is no 
assurance that we will be completely effective in ensuring our compliance 
with all applicable anti-corruption laws, including the Bribery Act, the FCPA 
or other legal requirements, including Trade Control laws. If we are not in 
compliance with the Bribery Act, the FCPA and other anti-corruption laws 
or Trade Control laws, we may be subject to criminal and civil penalties, 
disgorgement, debarment from debarment from government contracts 
as well as other sanctions and remedial measures, and may also result in 
collateral litigation. These consequences could have an adverse impact 
on our business, financial condition, results of operations and liquidity. 
Likewise, any investigation of any potential violations of the Bribery Act, the 
FCPA, other anti-corruption laws or Trade Control laws by United Kingdom, 
United States or other authorities could also have an adverse impact on our 
reputation, our business, results of operations and financial condition. In 
addition, responding to any enforcement action may result in a significant 
diversion of management’s attention and resources and significant defense 
costs and other professional fees.

The United Kingdom’s withdrawal from the European Union may have a 
negative effect on global economic conditions, financial markets and our 
business, which could reduce the price of our ADSs.

Since the end of the Brexit transition period on January 1, 2021, Great 
Britain (England, Scotland and Wales) has not been directly subject to EU 
laws, however under the terms of the Ireland/Northern Ireland Protocol, 
EU laws generally apply to Northern Ireland. On February 27, 2023, the UK 
Government and the European Commission reached a political agreement 
on the “Windsor Agreement” which will revise the Protocol on Ireland/
Northern Ireland in order to address some of the perceived shortcomings 
in its operation. Under the changes, Northern Ireland will be reintegrated 
under the regulatory authority of the MHRA with respect to medicinal 
products. The Windsor Framework was approved by the European 
Union-United Kingdom Joint Committee on March 24, 2023, so the UK 
government and the EU will enact legislative measures to bring it into 
law. On June 9, 2023, the MHRA announced that the medicines aspects 
of the Windsor Framework will apply from January 1, 2025. There could 
be additional uncertainty and risk around what these changes will mean 
to our business. It is currently unclear to what extent the UK Government 
will seek to align its regulations with the EU. The EU laws that have been 
transposed into UK law through secondary legislation remain applicable 
in Great Britain, but new legislation such as the (EU) CTR is not applicable 
in Great Britain. Whilst the EU-UK Trade and Cooperation Agreement, or 
TCA, includes the mutual recognition of Good Manufacturing Practice, or 
GMP, inspections of manufacturing facilities for medicinal products and 
GMP documents issued, it does not contain wholesale mutual recognition 
of UK and EU pharmaceutical regulations and product standards. There 
may be divergent local requirements in Great Britain from the EU in 
the future, which may impact clinical and development activities that 
occur in the UK in the future. Similarly, clinical trial submissions in the 
UK cannot be bundled with those of EU member states within the EMA 
Clinical Trial Information System, or CTIS, adding further complexity, 
cost and potential risk to future clinical and development activity in the 
UK. Significant political and economic uncertainty remains about how 
much the relationship between the UK and EU will differ as a result of the 
UK’s withdrawal. 

These developments, or the perception that any related developments 
could occur, have had and may continue to have a material adverse effect 
on global economic conditions and the stability of global financial markets, 
and may significantly reduce global market liquidity and restrict the ability 
of key market participants to operate in certain financial markets. Any 
of these factors could depress economic activity and restrict our access 
to capital, which could have a material adverse effect on our business, 
financial condition and results of operations and may adversely affect the 
market price of our ADSs.

The uncertainty regarding new or modified arrangements between the UK 
and other countries following the withdrawal may have a material adverse 
effect on the movement of personnel, goods, information or data between 
the UK and members of the EU and the United States, including the 
interruption of or delays in imports into the UK of goods originating within 
the EU and exports from the UK of goods originating there. For example, 
shipments into the UK of medicinal product substance manufactured for 
us in the EU may be interrupted or delayed and thereby prevent or delay 
the manufacture in the UK of drug product. Similarly, shipments out of 
the UK of drug product to the United States or the EU may be interrupted 
or delayed and thereby prevent or delay the delivery of drug product to 
clinical sites. Such a situation could hinder our ability to conduct current 
and planned clinical trials and have an adverse effect on our business.

Exchange rate fluctuations may materially affect our results of operations 
and financial condition.

Although we are based in the United Kingdom, our financial statements 
are denominated in U.S dollars and many of our business activities are 
carried out with partners outside the U.S. and United Kingdom and these 
transactions may be denominated in another currency. As a result, our 
business and the price of our ADSs may be affected by fluctuations in 
foreign exchange rates not only between the pound sterling and the 
U.S. dollar, but also the currencies of other countries, which may have 
a significant impact on our results of operations and cash flows from 
period to period. Currently, we do not have any exchange rate hedging 
arrangements in place.

Risks Related to Our Equity Securities and ADSs

The market price of our ADSs has been and will likely continue to be highly 
volatile, and you could lose all or part of your investment.

The market price of our ADSs has been and will likely continue to be 
volatile. The stock market in general, and the market for biopharmaceutical 
companies in particular, has experienced extreme volatility that has often 
been unrelated to the operating performance of particular companies. As 
a result of this volatility, you may not be able to sell your ADSs at or above 
the purchase price. The market price for our ADSs may be influenced by 
many factors, including:

 — adverse results or delays in our preclinical studies or clinical trials;

 — reports of AEs or other negative results in clinical trials of third parties’ 
therapeutic candidates that target the therapeutic candidates within 
our Internal Programs or our Founded Entities’ therapeutic candidates’ 
target indications;

 — an inability for us to obtain additional funding on reasonable 

terms or at all;

 — any delay in submitting an IND, BLA or NDA for the therapeutic 

candidates within our Internal Programs or our Founded Entities’ 
therapeutic candidates and any adverse development or perceived 
adverse development with respect to the FDA’s review of that 
IND, BLA or NDA;

 — failure to develop successfully and commercialize the therapeutic 
candidates within our Internal Programs or our Founded Entities’ 
therapeutic candidates;

 — announcements we make regarding our current therapeutic candidates, 
acquisition of potential new therapeutic candidates and companies and/
or in-licensing;

 — failure to maintain our or our Founded Entities’ existing license 

arrangements or enter into new licensing and collaboration agreements;

 — failure by us, our Founded Entities or our licensors to prosecute, maintain 

or enforce our intellectual property rights;

 — changes in laws or regulations applicable to future therapeutics;

 — inability to obtain adequate clinical or commercial supply for 

the therapeutic candidates within our Internal Programs or our 
Founded Entities’ therapeutic candidates or the inability to do so at 
acceptable prices;

 — adverse regulatory decisions, including failure to reach agreement with 
applicable regulatory authorities on the design or scope of our planned 
clinical trials;

 — failure to obtain and maintain regulatory exclusivity for the therapeutic 

candidates within our Internal Programs or our Founded Entities’ 
therapeutic candidates;

 — regulatory approval or commercialization of new therapeutics or other 
methods of treating our target disease indications by our competitors;

 — failure to meet or exceed financial projections we may provide to the 

public or to the investment community;

 — publication of research reports or comments by securities or 

industry analysts;

 — the perception of the pharmaceutical and biotechnology industries by 
the public, legislatures, regulators and the investment community;

 — announcements of significant acquisitions, strategic partnerships, 

joint ventures or capital commitments by us, our Founded Entities our 
strategic collaboration partners or our competitors;

 — disputes or other developments relating to proprietary rights, including 
patents, litigation matters and our or our Founded Entities’ ability to 
obtain patent protection for our technologies;

 — additions or departures of our key scientific or management personnel;

 — significant lawsuits, including patent or shareholder litigation, against us;

 — changes in the market valuations of similar companies;

 — adverse developments relating to any of the above or additional factors 

with respect to our Founded Entities;

 — sales or potential sales of substantial amounts of our ADSs; and

 — trading volume of our ADSs.

In addition, companies trading in the stock market in general, and 
Nasdaq, in particular, have experienced extreme price and volume 
fluctuations that have often been unrelated or disproportionate to the 
operating performance of these companies. Broad market and industry 
factors may negatively affect the market price of our ADSs, regardless of 
our actual operating performance. Since our ADSs were initially sold in 
November 2020 at a price of $33.00 per ADS, our ADS price has fluctuated 
significantly. If the market price of our ADSs does not exceed the price 
at which you acquired them, you may not realize any return on your 
investment in us and may lose some or all of your investment.

If securities or industry analysts do not publish research or publish 
inaccurate or unfavorable research about our business, our ADS price and 
trading volume could decline.

The trading market for our ADSs and ordinary shares depends in part 
on the research and reports that securities or industry analysts publish 
about us or our business. If no or few securities or industry analysts cover 
our company, the trading price for our ADSs and ordinary shares would 
be negatively impacted. If one or more of the analysts who covers us 
downgrades our equity securities or publishes incorrect or unfavorable 
research about our business, the price of our ordinary shares and ADSs 
would likely decline. If one or more of these analysts ceases coverage of 
our company or fails to publish reports on us regularly, or downgrades our 
securities, demand for our ordinary shares and ADSs could decrease, which 
could cause the price of our ordinary shares and ADSs or their trading 
volume to decline.

Future sales, or the possibility of future sales, of a substantial number 
of our securities could adversely affect the price of the shares and 
dilute shareholders.

Sales of a substantial number of our ADSs in the public market could occur 
at any time, subject to certain restrictions described below. If our existing 
shareholders sell, or indicate an intent to sell, substantial amounts of our 
securities in the public market, the trading price of the ADSs could decline 
significantly and could decline below the original purchase price. As of 
March 31, 2024, we had 270,209,101 outstanding ordinary shares. Ordinary 
shares subject to outstanding options under our equity incentive plans and 
the ordinary shares reserved for future issuance under our equity incentive 
plans will become eligible for sale in the public market in the future, subject 
to certain legal and contractual limitations.

Holders of ADSs are not treated as holders of our ordinary shares.

If you purchase an ADS, you will become a holder of ADSs with underlying 
ordinary shares in a company incorporated under English law. Holders 
of ADSs are not treated as holders of our ordinary shares, unless they 
withdraw the ordinary shares underlying their ADSs in accordance with the 
deposit agreement and applicable laws and regulations. The depositary 
is the holder of the ordinary shares underlying the ADSs. Holders of ADSs 
therefore do not have any rights as holders of our ordinary shares, other 
than the rights that they have pursuant to the deposit agreement. See 
“Description of Securities Other Than Equity Securities” in our Annual 
Report on Form 20-F.

Holders of ADSs may be subject to limitations on the transfer of their ADSs 
and the withdrawal of the underlying ordinary shares.

ADSs are transferable on the books of the depositary. However, the 
depositary may close its books at any time or from time to time when it 
deems expedient in connection with the performance of its duties. The 
depositary may refuse to deliver, transfer or register transfers of ADSs 
generally when our books or the books of the depositary are closed, or at 
any time if we or the depositary think it is advisable to do so because of 
any requirement of law, government or governmental body, or under any 
provision of the deposit agreement, or for any other reason, subject to 
the right of ADS holders to cancel their ADSs and withdraw the underlying 
ordinary shares. Temporary delays in the cancellation of your ADSs and 
withdrawal of the underlying ordinary shares may arise because the 
depositary has closed its transfer books or we have closed our transfer 
books, the transfer of ordinary shares is blocked to permit voting at 
a shareholders’ meeting or we are paying a dividend on our ordinary 
shares. In addition, ADS holders may not be able to cancel their ADSs and 
withdraw the underlying ordinary shares when they owe money for fees, 
taxes and similar charges and when it is necessary to prohibit withdrawals 
in order to comply with any laws or governmental regulations that apply to 
ADSs or to the withdrawal of ordinary shares or other deposited securities. 
See “Description of Securities Other Than Equity Securities” in our Annual 
Report on Form 20-F.

ADS holders may not be entitled to a jury trial with respect to claims 
arising under the deposit agreement, which could result in less favorable 
outcomes to the plaintiff(s) in any such action.

The deposit agreement governing the ADSs representing our ordinary 
shares provides that, to the fullest extent permitted by law, holders and 
beneficial owners of ADSs irrevocably waive the right to a jury trial of any 
claim they may have against us or the depositary arising out of or relating 
to the ADSs or the deposit agreement.

If this jury trial waiver provision is not permitted by applicable law, an 
action could proceed under the terms of the deposit agreement with a 
jury trial. If we or the depositary opposed a jury trial demand based on the 
waiver, the court would determine whether the waiver was enforceable 
based on the facts and circumstances of that case in accordance with the 
applicable state and federal law. To our knowledge, the enforceability of a 
contractual pre-dispute jury trial waiver in connection with claims arising

U.S. Supreme Court. However, we believe that a contractual pre-dispute 
jury trial waiver provision is generally enforceable, including under the laws 
of the State of New York, which govern the deposit agreement, by a federal 
or state court in the City of New York, which has non-exclusive jurisdiction 
over matters arising under the deposit agreement. In determining whether 
to enforce a contractual pre-dispute jury trial waiver provision, courts will 
generally consider whether a party knowingly, intelligently and voluntarily 
waived the right to a jury trial. We believe that this is the case with respect 
to the deposit agreement and the ADSs. It is advisable that you consult 
legal counsel regarding the jury waiver provision before entering into the 
deposit agreement.

If you or any other holders or beneficial owners of ADSs bring a claim 
against us or the depositary in connection with matters arising under the 
deposit agreement or the ADSs, including claims under federal securities 
laws, you or such other holder or beneficial owner may not be entitled to a 
jury trial with respect to such claims, which may have the effect of limiting 
and discouraging lawsuits against us and/or the depositary. If a lawsuit is 
brought against us and/or the depositary under the deposit agreement, it 
may be heard only by a judge or justice of the applicable trial court, which 
would be conducted according to different civil procedures and may result 
in different outcomes than a trial by jury would have had, including results 
that could be less favorable to the plaintiff(s) in any such action, depending 
on, among other things, the nature of the claims, the judge or justice 
hearing such claims, and the venue of the hearing.

No condition, stipulation or provision of the deposit agreement or ADSs 
serves as a waiver by any holder or beneficial owner of ADSs or by us or the 
depositary of compliance with the U.S. federal securities laws and the rules 
and regulations promulgated thereunder.

One of our principal shareholders has a significant holding in the company 
which may give them influence in certain matters requiring approval by 
shareholders, including approval of significant corporate transactions in 
certain circumstances.

As of March 31, 2024, Invesco Asset Management Limited, or Invesco, held 
approximately 23.76 percent of our ordinary shares. Accordingly, Invesco 
may, as a practical matter, be able to influence certain matters requiring 
approval by shareholders, including approval of significant corporate 
transactions in certain circumstances. Such concentration of ownership 
may also have the effect of delaying or preventing any future proposed 
change in control of the company. The trading price of the ordinary shares 
could be adversely affected if potential new investors are disinclined to 
invest in the company because they perceive disadvantages to a large 
shareholding being concentrated in the hands of a single shareholder. 
The interests of Invesco and the investors that acquire ADSs may not 
be aligned. Invesco may make acquisitions of, or investments in, other 
businesses in the same sectors as us or our Founded Entities. These 
businesses may be, or may become, competitors of us or our Founded 
Entities. In addition, funds or other entities managed or advised by Invesco 
may be in direct competition with us or our Founded Entities on potential 
acquisitions of, or investments in, certain businesses. In addition, Invesco 
holds equity interests in certain of our Founded Entities where they may 
exert direct influence.

You will not have the same voting rights as the holders of our ordinary 
shares and may not receive voting materials in time to be able to exercise 
your right to vote.

Except as described in our Annual Report on Form 20-F and the deposit 
agreement, holders of the ADSs will not be able to exercise voting rights 
attaching to the ordinary shares represented by the ADSs. Under the terms 
of the deposit agreement, holders of the ADSs may instruct the depositary 
to vote the ordinary shares underlying their ADSs. Otherwise, holders of 
ADSs will not be able to exercise their right to vote unless they withdraw 
the ordinary shares underlying their ADSs to vote them in person or by 
proxy in accordance with applicable laws and regulations and our Articles 
of Association. Even so, ADS holders may not know about a meeting far 
enough in advance to withdraw those ordinary shares. If we ask for the 
instructions of holders of the ADSs, the depositary, upon timely notice from 
us, will notify ADS holders of the upcoming vote and arrange to deliver 
our voting materials to them. Upon our request, the depositary will mail to 
holders a shareholder meeting notice that contains, among other things, a 
statement as to the manner in which voting instructions may be given. We 
cannot guarantee that ADS holders will receive the voting materials in time 
to ensure that they can instruct the depositary to vote the ordinary shares 
underlying their ADSs. A shareholder is only entitled to participate in, and 
vote at, the meeting of shareholders, provided that it holds our ordinary 
shares as of the record date set for such meeting and otherwise complies 
with our Articles of Association. In addition, the depositary’s liability to 
ADS holders for failing to execute voting instructions or for the manner 
of executing voting instructions is limited by the deposit agreement. As 
a result, holders of ADSs may not be able to exercise their right to give 
voting instructions or to vote in person or by proxy and they may not have 
any recourse against the depositary or us if their ordinary shares are not 
voted as they have requested or if their shares cannot be voted.

You may not receive distributions on our ordinary shares represented by 
the ADSs or any value for them if it is illegal or impractical to make them 
available to holders of ADSs.

The depositary for the ADSs has agreed to pay to you any cash dividends 
or other distributions it or the custodian receives on our ordinary shares 
or other deposited securities after deducting its fees and expenses. You 
will receive these distributions in proportion to the number of our ordinary 
shares your ADSs represent. However, in accordance with the limitations 
set forth in the deposit agreement, it may be unlawful or impractical to 
make a distribution available to holders of ADSs. We have no obligation to 
take any other action to permit distribution on the ADSs, ordinary shares, 
rights or anything else to holders of the ADSs. This means that you may not 
receive the distributions we make on our ordinary shares or any value from 
them if it is unlawful or impractical to make them available to you. These 
restrictions may have an adverse effect on the value of your ADSs.

Because we do not have immediate plans to pay any cash dividends on our 
ADSs, capital appreciation, if any, may be your sole source of gains and you 
may never receive a return on your investment.

Under current English law, a company’s accumulated realized profits must 
exceed its accumulated realized losses (on a non-consolidated basis) 
before dividends can be declared and paid. Therefore, we must have 
sufficient distributable profits before declaring and paying a dividend. 
We have not paid dividends in the past on our ordinary shares. We have 
not announced any immediate plans to pay any cash dividends. As a 
result, capital appreciation, if any, on our ADSs will be your sole source 
of gains for the foreseeable future, and you would suffer a loss on your 
investment if you were unable to sell your ADSs at or above the price that 
you initially paid for them. Investors seeking cash dividends should not 
purchase our ADSs.

Risks Related to Our Corporate Status 

We are not regulated as an “investment company” under the Investment 
Company Act of 1940, as amended, or the 1940 Act, and if we were 
deemed an “investment company” under the 1940 Act, applicable 
restrictions could make it impractical for us to continue our business as 
contemplated and could have a material adverse effect on our business.

The 1940 Act and the rules thereunder contain detailed parameters for the 
organization and operation of investment companies. Among other things, 
the 1940 Act and the rules thereunder limit or prohibit transactions with 
affiliates, impose limitations on the issuance of debt and equity securities 
and impose certain governance requirements. We have not been and do 
not intend to become regulated as an investment company, and we intend 
to conduct our activities so that we will not be deemed to be an investment 
company under the 1940 Act. In order to ensure that we are not deemed 
to be an investment company, we may be limited in the assets that we may 
continue to own and, further, may need to dispose of or acquire certain 
assets at such times or on such terms as may be less favorable to us than 
in the absence of such requirement. If anything were to happen which 
would cause us to be deemed to be an investment company under the 
1940 Act (such as significant changes in the value of our Founded Entities 
or a change in circumstance that results in a reclassification of our interests 
in our Founded Entities for purposes of the 1940 Act), the requirements 
imposed by the 1940 Act could make it impractical for us to continue our 
business as currently conducted, which would materially adversely affect 
our business, results of operations and financial condition. In addition, if 
we were to become inadvertently subject to the 1940 Act, any violation of 
the 1940 Act could subject us to material adverse consequences, including 
potentially significant regulatory penalties and the possibility that certain 
of our contracts could be deemed unenforceable.

As a foreign private issuer, we are exempt from a number of rules under the 
U.S. securities laws and are permitted to file less information with the SEC 
than a U.S. company. This may limit the information available to holders of 
ADSs or our ordinary shares.

We are a “foreign private issuer,” as defined in the SEC’s rules and 
regulations and, consequently, we are not subject to all of the disclosure 
requirements applicable to U.S. domestic public companies. For example, 
we are exempt from certain rules under the Exchange Act that regulate 
disclosure obligations and procedural requirements related to the 
solicitation of proxies, consents or authorizations applicable to a security 
registered under the Exchange Act, including the U.S. proxy rules under 
Section 14 of the Exchange Act. In addition, our officers and directors are 
exempt from the reporting and “short-swing” profit recovery provisions 
of Section 16 of the Exchange Act and related rules with respect to their 
purchases and sales of our securities. Moreover, while we currently make 
annual and semi-annual filings with respect to our listing on the LSE, we 
will not be required to file periodic reports and financial statements with 
the SEC as frequently or as promptly as U.S. domestic issuers and will not 
be required to file quarterly reports on Form 10-Q or current reports on 
Form 8-K under the Exchange Act. In addition, “foreign private issuers” 

Risk Factor Annex continuedAdditional informationPureTech Health plc   Annual Report and Accounts 2023    221  

are exempt from Regulation FD, which prohibits selective disclosures 
of material information. Accordingly, there will be less publicly available 
information concerning our company than there would be if we were not 
a foreign private issuer. 

As a foreign private issuer, we are permitted to adopt certain home 
country practices in relation to corporate governance matters that differ 
significantly from Nasdaq corporate governance listing standards. These 
practices may afford less protection to shareholders than they would enjoy 
if we complied fully with corporate governance listing standards.

As a foreign private issuer listed on Nasdaq, we are subject to corporate 
governance listing standards. However, rules permit a foreign private issuer 
like us to follow the corporate governance practices of its home country. 
Certain corporate governance practices in the United Kingdom, which 
is our home country, may differ significantly from corporate governance 
listing standards. For example, neither the corporate laws of the United 
Kingdom nor our articles of association require a majority of our directors 
to be independent and we could include non-independent directors 
as members of our nomination and remuneration committee, though a 
majority is required, and our independent directors would not necessarily 
hold regularly scheduled meetings at which only independent directors 
are present. Currently, we follow home country practice to the maximum 
extent possible. Therefore, our shareholders may be afforded less 
protection than they otherwise would have under corporate governance 
listing standards applicable to U.S. domestic issuers. See “Governance” of 
this Annual Report and Accounts and “Item 16G—Corporate Governance” 
of our Annual Report on Form 20-F.

We may lose our foreign private issuer status in the future, which could 
result in significant additional cost and expense.

While we currently qualify as a foreign private issuer, the determination of 
foreign private issuer status is made annually on the last business day of an 
issuer’s most recently completed second fiscal quarter and, accordingly, 
the next determination will be made with respect to us on June 30, 2024.

In the future, we would lose our foreign private issuer status if we to fail to 
meet the requirements necessary to maintain our foreign private issuer 
status as of the relevant determination date. For example, if more than 
50 percent of our securities are held by U.S. residents and more than 50 
percent of the members of our executive committee or members of our 
board of directors are residents or citizens of the United States, we could 
lose our foreign private issuer status.

The regulatory and compliance costs to us under U.S. securities laws 
as a U.S. domestic issuer may be significantly more than costs we incur 
as a foreign private issuer. If we are not a foreign private issuer, we will 
be required to file periodic reports and registration statements on U.S. 
domestic issuer forms with the SEC, which are more detailed and extensive 
in certain respects than the forms available to a foreign private issuer. 
We would be required under current SEC rules to prepare our financial 
statements in accordance with U.S. GAAP, rather than IFRS, and modify 
certain of our policies to comply with corporate governance practices 
associated with U.S. domestic issuers. Such conversion of our financial 
statements to U.S. GAAP will involve significant time and cost. In addition, 
we may lose our ability to rely upon exemptions from certain corporate 
governance requirements on U.S. stock exchanges that are available to 
foreign private issuers such as the ones described above and exemptions 
from procedural requirements related to the solicitation of proxies.

Risks Related to Our Internal Controls
Failure to maintain effective internal control over financial reporting 
could have a material adverse effect on our business, financial condition, 
results of operations, and stock price and may adversely affect investor 
confidence in our company and, as a result, the value of our ADSs and 
your investment. Section 404 of the Sarbanes-Oxley Act requires us to 
evaluate the effectiveness of our internal controls over financial reporting 
as of the end of each fiscal year, including a management report assessing 
the effectiveness of our internal controls over financial reporting, and a 
report issued by our independent registered public accounting firm on 
that assessment. Our ability to comply with the annual internal control 
reporting requirements will depend on the effectiveness of our financial 
reporting and data systems and controls across our company. We expect 
these systems and controls to require additional investment as we 
become increasingly more complex and our business grows. To effectively 
manage this complexity, we will need to continue to maintain and revise 
our operational, financial and management controls, and our reporting 
systems and procedures. Certain weaknesses or deficiencies or failures to 
implement required new or improved controls, or difficulties encountered 
in the implementation or operation of these controls, could harm our 
operating results and cause us to fail to meet our financial reporting 
obligations, or result in material misstatements in our financial statements, 
which could adversely affect our business and reduce the value of our 
ADSs. We previously identified and disclosed a material weakness in our 

internal control over financial reporting in our Annual Report on Form 20-F 
for the year ended December 31, 2021. This material weakness has since 
been remediated, but we may discover additional material weaknesses 
in our internal control over financial reporting in the future, which we 
may not successfully remediate on a timely basis or at all. Any failure to 
remediate any significant deficiencies or material weaknesses identified 
by us or to implement required new or improved controls, or difficulties 
encountered in their implementation, could cause us to fail to meet our 
reporting obligations. 

If we fail to maintain effective internal control over financial reporting, we 
could suffer material misstatements in our financial statements and fail 
to meet our reporting obligations, which could cause investors to lose 
confidence in our reported financial information. This could in turn limit 
our access to capital markets or lead to a decline in the trading price of 
our securities. We may also be required to restate our financial statements 
from prior periods. Additionally, ineffective internal control over financial 
reporting could expose us to increased risk of fraud or misuse of corporate 
assets and subject us to potential delisting from the stock exchange on 
which we list, regulatory investigations, litigation from shareholders and 
civil or criminal sanctions, which could have a material adverse effect 
on our business.

Our disclosure controls and procedures may not prevent or detect all errors 
or acts of fraud.

We are subject to certain reporting requirements of the Exchange Act. 
Our disclosure controls and procedures are designed to reasonably 
assure that information required to be disclosed by us in reports we file 
or submit under the Exchange Act is accumulated and communicated 
to management, recorded, processed, summarized and reported within 
the time periods specified in the rules and forms of the SEC. We believe 
that any disclosure controls and procedures or internal controls and 
procedures, no matter how well conceived and operated, can provide 
only reasonable, not absolute, assurance that the objectives of the 
control system are met. These inherent limitations include the realities 
that judgments in decision-making can be faulty, and that breakdowns 
can occur because of simple error or mistake. Additionally, controls can 
be circumvented by the individual acts of some persons, by collusion 
of two or more people or by an unauthorized override of the controls. 
Accordingly, because of the inherent limitations in our control system, 
misstatements or insufficient disclosures due to error or fraud may occur 
and not be detected.

Risks Related to Tax Matters

We are treated as a U.S. domestic corporation for U.S. federal 
income tax purposes.

We are treated as a U.S. domestic corporation for U.S. federal income tax 
purposes under Section 7874(b) of the Internal Revenue Code of 1986, as 
amended, or the Code. As a result, we are subject to U.S. income tax on 
our worldwide income and any dividends paid by us (or deemed to be paid 
by us for U.S. federal income tax purposes) to Non-U.S. Holders (as defined 
in the discussion under “Taxation in the United States” in our Annual 
Report on Form 20-F) will generally be subject to U.S. federal income 
tax withholding at a 30 percent rate or such lower rate as provided in an 
applicable treaty. Furthermore, PureTech Health plc is also resident for tax 
purposes in the U.K. and subject to U.K. corporation tax on its worldwide 
income and gains. Consequently, we may be liable for both U.S. and U.K. 
income tax, which could have a material adverse effect on our financial 
condition and results of operations.

This discussion of certain U.S. federal income tax risks is subject in its 
entirety to the summaries set forth in “Certain United Kingdom Tax 
Considerations” and “Taxation in the United States” in our Annual 
Report on Form 20-F.

Our ability to use our U.S. net operating losses and certain other tax 
attributes to offset future U.S. taxable income and income tax liabilities 
may be subject to certain limitations.

As of December 31, 2023, we had U.S. federal and state net operating loss 
carryforwards, or NOLs, of approximately $13.7 million and $111.5 million, 
respectively, which, subject to the following discussion, are generally 
available to be carried forward to offset our future taxable income, if any, 
until such NOLs are used or expire. Our federal NOLs generated in taxable 
years beginning after December 31, 2017 are not subject to expiration, 
but may generally only be used to offset 80% of taxable income in years 
beginning after December 31, 2020. As of December 31, 2023, we also 
had U.S. federal and state research and development and other tax credit 
carryforwards of approximately $2.3 million and $0.1 million, respectively, 
available to reduce our future income tax liabilities, if any. These NOLs 
and tax credit carryforwards could expire unused, to the extent subject to 
expiration, and be unavailable to offset future taxable income or income 
tax liabilities.

Risk Factor Annex continuedAdditional information222    PureTech Health plc   Annual Report and Accounts 2023

In general, under Sections 382 and 383 of the Code, a corporation that 
undergoes an “ownership change,” generally defined as a greater than 
50 percentage point change (by value) in its equity ownership by certain 
shareholders or groups of shareholders over a rolling three year period, 
is subject to limitations on its ability to utilize its pre-change U.S. federal 
NOLs and tax credit carryforwards to offset future taxable income and 
income tax liabilities. Similar rules may apply under state law. Our existing 
federal NOLs and tax credits may be subject to limitation arising from 
previous ownership changes. Future changes in our stock ownership, some 
of which are outside of our control, could result in ownership changes 
under Sections 382 or 383 of the Code, and our ability to utilize our federal 
NOLs or tax credit carryforwards could be further limited.

Additionally, we may not be able to utilize the NOLs or tax credit 
carryforwards of our Founded Entities that have been deconsolidated 
or that will deconsolidate in the future. Furthermore, our ability to utilize 
NOLs of companies that we have acquired or may acquire in the future may 
be subject to similar limitations.

For these reasons, even if we attain profitability, we may not be able to 
realize a tax benefit from the use of our NOLs or tax credit carryforwards.

We may be unable to use net operating loss and tax credit carryforwards 
and certain built-in losses to reduce future U.K. tax liabilities.

As a U.K. incorporated and tax resident entity, PureTech Health plc is 
subject to U.K. corporate taxation on its tax-adjusted trading profits. Due 
to the nature of our business, PureTech Health plc has generated losses 
since inception and therefore we have not paid any U.K. corporation tax. 
Subject to numerous utilization criteria and restrictions (including those 
that limit the percentage of profits that can be reduced by carried forward 
losses and those that can restrict the use of carried forward losses where 
there is a change of ownership of more than half the ordinary shares of the 
company and a major change in the nature, conduct or scale of the trade), 
we expect these to be eligible for carry forward and utilization against 
future U.K. operating profits.

Future changes to tax laws could materially adversely affect our company 
and reduce net returns to our shareholders.

The tax treatment of the company is subject to changes in tax laws, 
regulations and treaties, or the interpretation thereof, tax policy initiatives 
and reforms under consideration and the practices of tax authorities 
in jurisdictions in which we operate, as well as tax policy initiatives and 
reforms related to the Organisation for Economic Co-Operation and 
Development’s, or OECD, Base Erosion and Profit Shifting, or BEPS, 
Project, the European Commission’s state aid investigations and other 
initiatives. Such changes may include (but are not limited to) the taxation 
of operating income, investment income, dividends received or (in the 
specific context of withholding tax) dividends paid. We are unable to 
predict what tax reform may be proposed or enacted in the future or what 
effect such changes would have on our business, but such changes, to 
the extent they are brought into tax legislation, regulations, policies or 
practices, could affect our financial position and overall or effective tax 
rates in the future in countries where we have operations, reduce post-tax 
returns to our shareholders, and increase the complexity, burden and cost 
of tax compliance.

Tax authorities may disagree with our positions and conclusions regarding 
certain tax positions, resulting in unanticipated costs, taxes or non-
realization of expected benefits.

A tax authority may disagree with tax positions that we have taken, which 
could result in increased tax liabilities. For example, HM Revenue & 
Customs, or HMRC, the Internal Revenue Service or another tax authority 
could challenge our allocation of income by tax jurisdiction and the 
amounts paid between certain of our Founded Entities pursuant to our 
intercompany arrangements and transfer pricing policies, including 
amounts paid with respect to our intellectual property development. 
Similarly, a tax authority could assert that we are subject to tax in 
a jurisdiction where we believe we have not established a taxable 
connection, often referred to as a “permanent establishment” under 
international tax treaties, and such an assertion, if successful, could 
increase our expected tax liability in one or more jurisdictions. A tax 
authority may take the position that material income tax liabilities, interest 
and penalties are payable by us, in which case, we expect that we might 
contest such assessment. Contesting such an assessment may be lengthy 
and costly and if we were unsuccessful in disputing the assessment, 
the implications could increase our anticipated effective tax rate, 
where applicable.

Shareholder protections found in provisions under the U.K. City Code 
on Takeovers and Mergers, or the Takeover Code, will not apply if our 
securities are no longer admitted to trading on a regulated market or a 
multilateral trading facility in the United Kingdom or on any stock exchange 
in the Channel Islands or the Isle of Man and our place of management and 
control is considered to change to outside the United Kingdom.

We are registered as a public limited company incorporated in England 
and Wales and have our ordinary shares admitted to trading on a 
regulated market in the United Kingdom (being the main market of the 
LSE). Accordingly, we are currently subject to the Takeover Code and, as 
a result, our shareholders are entitled to the benefit of certain takeover 
offer protections provided under the Takeover Code. The Takeover Code 
provides a framework within which takeovers of companies are regulated 
and conducted. If, at the time of a takeover offer, we have de-listed from 
the main market of the LSE (and do not maintain a listing of securities on 
any other regulated market or a multilateral trading facility in the United 
Kingdom or on any stock exchange in the Channel Islands or the Isle of 
Man) and the Panel on Takeovers and Mergers determine that we do not 
have our place of central management and control in the United Kingdom, 
then the Takeover Code may not apply to us and our shareholders would 
not be entitled to the benefit of the various protections that the Takeover 
Code affords. In particular, we would not be subject to the rules regarding 
mandatory takeover bids. The following is a brief summary of some of the 
most important rules of the Takeover Code:

 — when any person acquires, whether by a series of transactions over a 
period of time or not, an interest in shares which (taken together with 
shares already held by that person and an interest in shares held or 
acquired by persons acting in concert with him or her) carry 30 percent 
or more of the voting rights of a company that is subject to the Takeover 
Code, that person is generally required to make a mandatory offer 
to all the holders of any class of equity share capital or other class of 
transferable securities carrying voting rights in that company to acquire 
the balance of their interests in the company;

 — when any person who, together with persons acting in concert with him 
or her, is interested in shares representing not less than 30 percent but 
does not hold more than 50 percent of the voting rights of a company 
that is subject to the Takeover Code, and such person, or any person 
acting in concert with him or her, acquires an additional interest in shares 
which increases the percentage of shares carrying voting rights in which 
he or she is interested, then such person is generally required to make 
a mandatory offer to all the holders of any class of equity share capital 
or other class of transferable securities carrying voting rights of that 
company to acquire the balance of their interests in the company;

 — a mandatory offer triggered in the circumstances described in the 

two paragraphs above must be in cash (or be accompanied by a cash 
alternative) and at not less than the highest price paid within the 
preceding 12 months to acquire any interest in shares in the company by 
the person required to make the offer or any person acting in concert 
with him or her;

 — in relation to a voluntary offer (i.e. any offer which is not a mandatory 
offer), when interests in shares representing 10 percent or more of 
the shares of a class have been acquired for cash by an offeror (i.e., a 
bidder) and any person acting in concert with it in the offer period and 
the previous 12 months, the offer must be in cash or include a cash 
alternative for all shareholders of that class at not less than the highest 
price paid for any interest in shares of that class by the offeror and by 
any person acting in concert with it in that period. Further, if an offeror 
acquires for cash any interest in shares during the offer period, a cash 
alternative must be made available at not less than the highest price paid 
for any interest in the shares of that class;

 — if the offeror acquires an interest in shares in an offeree company (i.e., 
a target) at a price higher than the value of the offer, the offer must be 
increased to not less than the highest price paid for the interest in shares 
so acquired;

 — the offeree company must obtain competent advice as to whether the 
terms of any offer are fair and reasonable and the substance of such 
advice must be made known to all the shareholders, together with the 
opinion of the board of directors of the offeree company;

 — special or favorable deals for selected shareholders are not permitted, 

except in certain circumstances where independent shareholder 
approval is given and the arrangements are regarded as fair and 
reasonable in the opinion of the financial adviser to the offeree;

Risk Factor Annex continuedAdditional informationPureTech Health plc   Annual Report and Accounts 2023    223  

 — all shareholders must be given the same information;

 — each document published in connection with an offer by or on behalf of 
the offeror or offeree must state that the directors of the offeror or the 
offeree, as the case may be, accept responsibility for the information 
contained therein;

 — profit forecasts, quantified financial benefits statements and asset 

valuations must be made to specified standards and must be reported on 
by professional advisers;

 — misleading, inaccurate or unsubstantiated statements made in 

documents or to the media must be publicly corrected immediately;

 — actions during the course of an offer by the offeree company, which 

might frustrate the offer are generally prohibited unless shareholders 
approve these plans. Frustrating actions would include, for example, 
lengthening the notice period for directors under their service contract 
or agreeing to sell off material parts of the target group;

 — stringent and detailed requirements are laid down for the disclosure 

of dealings in relevant securities during an offer, including the prompt 
disclosure of positions and dealing in relevant securities by the parties 
to an offer and any person who is interested (directly or indirectly) in 
1 percent or more of any class of relevant securities; and employees of 
both the offeror and the offeree company and the trustees of the offeree 
company’s pension scheme must be informed about an offer. In addition, 
the offeree company’s employee representatives and pension scheme 
trustees have the right to have a separate opinion on the effects of the 
offer on employment appended to the offeree board of directors’ circular 
or published on a website.
