Highlights 2023
Highlights - Avacta Therapeutics
The results to date show that 
AVA6000, the first peptide drug 
conjugate in the Avacta pipeline, 
has a favourable safety profile with 
concentration of the warhead in the 
TME resulting in multiple responses in 
patients with high levels of Fibroblast 
Activation Protein (‘FAPhigh’), thus 
delivering clinical proof-of-concept for 
AVA6000 and proof-of-mechanism for 
the proprietary pre|CISIONTM drug 
delivery platform.
The growing body of 
clinical and pre-clinical data 
validating the pre|CISIONTM 
platform has supported an 
acceleration in the Group’s 
commercial activities 
including the appointment 
of Dr Simon Bennett as 
Chief Business Officer of the 
Therapeutics Division. 
In the three-weekly dose 
escalation study for AVA6000 
the seventh dose cohort was 
successfully completed and, 
in light of the highly positive 
safety data, patients are 
now being dosed in a two-
weekly dose escalation study 
with the aim of defining 
the recommended Phase 2 
dose ('RP2D'), allowing dose 
expansion cohorts to begin in 
H2 2024 followed by the Phase 
2 efficacy study in a selected 
orphan indication.
Data from the three-weekly 
study confirm the ability of 
the pre|CISIONTM platform 
to concentrate a therapeutic 
warhead in the tumour 
microenvironment (‘TME’) 
to transform the safety 
profile in patients with 
advanced cancers. 
Encouraging 
clinical data for AVA6000,

highlights
A clinical stage oncology drug company developing 
innovative cancer therapies based on its two proprietary 
technology platforms: pre|CISIONTM and Affimer® 
AffyXell Therapeutics ('AffyXell'), 
the joint venture between Avacta 
and Daewoong Pharmaceutical 
('Daewoong') continued to progress 
well with the triggering of a second 
milestone payment. This has resulted in 
an increase in Avacta’s shareholding in 
AffyXell to 25%.

Appointment of Christina 
Coughlin MD, PhD as 
Head of Research and 
Development, to drive 
the clinical development 
strategy for AVA6000, 
Avacta’s lead pre|CISION™ 
tumour targeted therapy  
and the broader drug 
pipeline strategy.
Data from the AVA6000 
Phase 1 clinical trial 
three-weekly dose 
escalation study 
reported at the AACR 
annual meeting 
in San Diego, US, 
providing Clinical 
Proof of Concept for 
AVA6000 with multiple 
patient responses and 
favourable safety profile.
The Group announced that 
patients are now being dosed in 
a two-weekly dose escalation 
study with the aim of defining 
the recommended Phase 2 
dose ('RP2D'), allowing dose 
expansions to begin in H2 
2024 followed by the Phase 
2 efficacy study in a selected 
orphan indication.
Patients in the two-weekly study in 
each cohort can be dosed in parallel, 
allowing the Company to remain on 
track to begin the dose expansion 
studies in the second half of 2024.
Avacta receives 
approval to enrol 
patients in the 
UK in the ongoing 
two-weekly dose 
escalation study.

CLINICAL TRIAL METHODS
BACKGROUND AND PRECLINICAL DATA
MECHANISM OF ACTION OF AVA6000
Fibroblast activation protein-a (FAP) is an 
extracellular post-proline protease that is 
upregulated in many solid tumors in a 
membrane-bound form on cancer associated 
fibroblasts as well as tumor cells. FAP activity is 
also observed as a soluble protease to a low 
degree in plasma
AVA6000 is a peptide drug conjugate, that 
leverages the tumor-specific expression of FAP 
by linking a peptide moiety that is specifically 
cleaved by FAP to doxorubicin
The peptide moiety linker (pre|CISION ) 
prevents cellular entry of doxorubicin unless 
cleaved by FAP, thus enabling targeted delivery 
of doxorubicin to tumors
AVA6000 was assessed in a 
multi-center, ascending 
dose first-in-human Phase 1 
trial in patients (Data cutoff 
presented is 11 March 2024). 
The patient population 
included the following:
IN VIVO CHARACTERIZATION 
OF AVA6000
The antitumor activity of AVA6000 was 
assessed in two in vivo xenograft models, one 
with low and one with high tumor:plasma FAP 
activity
As shown in Fig. 2 (left panel), the model with 
a low activity ratio (HPAF-II) has limited activity 
of AVA6000, similar to doxorubicin.  However, 
significant antitumor activity with a dose 
response is demonstrated in the setting of 
high tumor:plasma FAP activity in Fig. 2 (right 
panel) suggesting that patients with tumors 
with high FAP activity will be more sensitive to 
the AVA6000 mechanism of action

FIGURE 7. EFFICACY AND SEVERE NEUTROPENIA 
OBSERVED AT DIFFERENT EXPOSURES
Figure 7. Efficacy with AVA6000 is Observed at Lower Exposures than Severe 
Neutropenia  
Logistic regression analysis of the relationship between response (PR, MR, 
SD>16weeks), severe neutropenia and dose indicates high probability of 
responses at a range of exposures (correlating to 250 – 310 mg/m2) compared with 
observation of severe neutropenia. Exposure for individual patients with tumor 
shrinkage (PR/MR) are included with black dots (1 PR with dose reduction)
Key Finding: 
Responses are observed 
at AVA6000 doses with 
doxorubicin exposures 
much lower than that 
reported with standard 
dose doxorubicin.  This 
suggests a more 
frequent schedule at 
these doses may 
enhance efficacy while 
not increasing toxicity

The Avacta pre|CISIONTM platform is a proprietary warhead 
delivery system, based on the activity of a cancer-specific 
protease, that is designed to concentrate highly potent 
warheads in the tumour microenvironment while sparing 
normal tissues. 
Fibroblast activation protein-α ('FAP') is an extracellular post-
proline protease that is upregulated in many solid tumours in 
a membrane-bound form on cancer associated fibroblasts as 
well as tumour cells. FAP activity is also observed as a soluble 
protease to a low degree in plasma. 
AVA6000 is the first clinical-stage pre|CISIONTM molecule. It is 
a peptide drug conjugate that leverages the tumour-specific 
expression of FAP by linking a peptide moiety which has two 
key properties: 
•	 It prevents the warhead from entering cells. 
•	 It is specifically cleaved by FAP to release active 
doxorubicin. 
The peptide moiety linker, pre|CISION™, prevents cellular 
entry of the warhead unless it is cleaved by FAP, thus enabling 
targeted delivery of doxorubicin to tumours.

Affimer® reagents are small proteins that can 
be engineered to bind to a target molecule 
of interest, in the same way that an antibody 
does, but with a number of competitive 
advantages over antibodies. 
Affimer® regents can be used to develop diagnostic 
and research assays, or products to enrich or purify a 
target from a complex mixture. If the target is involved 
in a disease pathway and binding by the Affimer® 
molecule activates, alters or blocks its function, then 
there is potential for the Affimer® molecule to provide 
therapeutic benefit as a drug. 
Antibodies are proteins that have evolved as part of 
the immune system to bind to a target in vivo. Over 
several decades this property of antibodies has been 
harnessed to develop thousands of reagents for 
laboratory assays and diagnostic tests, and one third 
of all drugs in development are now antibodies. This 
enormous success of antibodies is despite some 
significant limitations. These limitations are that: 
•	 antibodies are often not entirely specific to the target 
and cross-react with other targets causing uncertainty 
in the results that are obtained or drug side-effects; 
•	 antibodies are large proteins with complex 
structures, including special internal bonds 
and external chemical modifications that are 
required for correct function, making many of 
them challenging and costly to manufacture and 
resulting in batch-to-batch variability; 
•	 antibodies are often generated by immunising 
an animal and purifying the antibodies from 
the animal’s blood, which means that the time 
required to develop a new, high-quality antibody 
can be many months and that the type of target to 
which an antibody can be raised is limited to those 
that are not toxic and cause an immune response; 
many important and commercially valuable targets 
do not fit these criteria; 
•	 the large size of antibodies is a disadvantage in 
some applications in which, for example, tissue 
penetration is important or a high density on a 
sensor surface is required; and 
•	 many applications require the antibody to be 
modified to carry a payload or signalling tag and 
their large size and complex structure makes 
these modifications more challenging.
In contrast, the small size and simple structure of 
Affimer® molecules means that they are easy to 
manufacture with simple, low-cost processes that 
are reliable in their batch-to-batch consistency. Their 
simplicity also means that modifying an Affimer® 
molecule for a particular application is easily carried 
out with simple biochemistry. 
New Affimer® molecules are generated by screening 
through a pre-existing large library of approximately 
ten billion Affimer® molecules to identify those that 
bind to the target of interest. This utilises an industry 
standard in vitro process which does not use animals 
and therefore it is quick, taking a matter of weeks, 
and circumvents limitations arising from the need 
for an immune response in an animal. This screening 
process can also be finely controlled to maximise 
the specificity and optimise other properties of the 
Affimer® molecules that are identified in the library 
for a particular application. 
Affimer® molecules are ten times smaller than 
antibodies and are very stable, being resistant to 
extremes of pH and temperature, which makes them 
better suited to some applications where harsh 
conditions are experienced or where their small size 
leads to better tissue penetration or a higher density 
of binding sites on a surface. Their small size and the 
ease with which they can be modified means that the 
amount of time a therapeutic Affimer® molecule stays 
in the bloodstream can be tailored to suit different 
therapeutics regimes.
Despite the limitations outlined above, antibodies 
have become the dominant technology in markets 
worth in excess of $100 billion annually. Therefore, 
the opportunity for an alternative such as Affimer® 
technology is very large with the potential to generate 
near-term revenue from diagnostics, as well as potentially 
generating much higher rewards from therapeutics but 
with associated greater development risk.

I believe that Avacta has reached a pivotal point in its 
history. The clinical progress of the pre|CISION™ platform 
and of AVA6000 enable the Company to bring singular 
focus to the Therapeutics Division, though clinical 
development and partnering.
We are also aware of the need to continue to evolve the 
Board of Directors to best suit the needs of an AIM-listed 
clinical stage cancer treatments company, to strategically 
manage the Diagnostics Division for the best outcome for 
our staff, customers and shareholders alike, and to create 
financial optionality with respect to the company bond. 
The Board of Directors and I are excited about what is to 
come for Avacta.
The AVA6000 clinical data continue to impress. As we 
begin to progress into the expansion cohorts and Phase 
2 study and hopefully continue to demonstrate clear 
patient benefits, I am confident this will further open up 
the commercial partnering opportunities for AVA6000 
and the pre|CISION™ technology platform.
During the year there have been some changes to the 
Board, including the appointment of Shaun Chilton as 
Non-executive Director in June 2023. Shaun has held a 
number of senior and executive commercial positions, 
with more than 30 years’ experience in the pharmaceutical 
and pharmaceutical services industries, most recently as 
Chief Executive Officer of Clinigen. We believe he will bring 
invaluable experience to the Company.
Christina Coughlin MD, who joined the Board as a Non-
executive Director in March 2022 and acted as Medical 
Advisor in the latter half of the year, has now joined 
the Board on a full-time basis as Head of Research 
and Development in February 2024. Chris, a talented 
oncologist and immunologist, has been pivotal in driving 
the clinical development strategy for AVA6000 and will 
be responsible for all pre-clinical research and clinical 
development activities.
The Board will need to continue to evolve to meet the 
demands of being a clinical stage oncology Company 
and to more clearly communicate with shareholders and 
other stakeholders.

Strategic Report

The clinical data emerging from the AVA6000 Phase 1 study 
during 2023 clearly validate the pre|CISIONTM platform as 
a leading tumour-targeting mechanism. Targeting tumour 
tissue and reducing systemic exposure are key objectives in 
oncology drug development allowing more potent therapies 
to be utilised. The potential of a successful tumour-targeting 
platform is huge. 
AVA6000, Avacta’s first pre|CISIONTM peptide drug conjugate, 
has been shown to target doxorubicin to FAP-rich tumour 
tissue, dramatically improving the safety and tolerability 
of this well-established chemotherapy. Early signs of anti-
tumour activity have been seen in a number of patients on 
the trial meaning that clinically effective levels of the drug are 
being released in the tumour microenvironment. This also 
reflects the tumour biopsy data which show doxorubicin 
being present in the tumour tissue at many times the level 
measured in the blood stream at the same timepoint showing 
effectiveness in the tumour whilst minimising the debilitating 
side effects characteristically experienced with chemotherapy.
Avacta has been able to leverage this excellent progress in 
the clinic to progress conversations with potential commercial 
partners. The commercial strategy is to continue to develop 
AVA6000 through the Phase 2 efficacy study to maximise 
value. However, there are significant partnering opportunities 
for the broader pre|CISIONTM platform. The body of positive 
clinical data we have seen will support our commercial activities.
The Group’s focus is on growing shareholder value through 
its oncology drug programmes. The Diagnostics Division has 
been executing the plan that was set out to shareholders in 
October 2022 to build a valuable in vitro diagnostics business 
serving the needs of healthcare professionals. It has grown 
through two acquisitions, resulting in a combined revenue of 
£21.2 million, and is on a trajectory to become EBITDA positive 
in the near future with the acquired businesses showing 10% 
growth during 2023.
The fundraise completed post-period end in March 2024 
amounting to £31.1 million (gross proceeds) from new and 
existing institutional and private shareholders has enabled 
us to significantly extend the Group’s cash runway, creating a 
strong negotiating position in future commercial discussions 
and providing the funds to progress AVA6000 into Phase 2 
clinical trials, subject to FDA approval.

Avacta Report and Accounts          2023

Operational Review  
Business overview
Avacta is a healthcare group developing 
innovative cancer drugs and powerful  
in vitro diagnostics to improve human 
health and well-being. 
Avacta is addressing these key challenges in 
healthcare through two separate divisions: an 
oncology biotech division harnessing proprietary 
therapeutic platforms to develop novel, highly 
targeted cancer drugs, and its Diagnostics Division 
focused on supporting healthcare professionals and 
broadening access to testing. 
Avacta's two proprietary platforms, pre|CISION™ 
and Affimer®, underpin its cancer therapeutics whilst 
the Diagnostics Division is focused on innovative 
product development, the commercial routes to 
market and leveraging the Affimer® platform to drive 
competitive advantage. 
The pre|CISION™ platform modifies chemotherapy 
to be activated only in the tumour tissue, reducing 
systemic exposure and toxicity. This is achieved by 
harnessing an enzyme called FAP which is highly 
upregulated in most solid tumours compared 
with healthy tissues, turning chemotherapy into a 
peptide drug conjugate ‘precision medicine’. The lead 
pre|CISION™ programme, AVA6000 a peptide drug 
conjugate tumour-activated form of doxorubicin, 
is in Phase 1 studies and has shown dramatic 
improvement in safety compared with standard 
doxorubicin, and preliminary signs of clinical efficacy. 
Affimer® is a novel biologic platform which has 
significant technical and commercial advantages 
compared with antibodies and is used both to 
develop advanced immunotherapies and to improve 
the performance of immunodiagnostics. 
Avacta’s Diagnostics Division comprises two business 
units – Launch Diagnostics and Coris BioConcept. 
Avacta acquired UK-based IVD distributor Launch 
Diagnostics which has provided Avacta with well-
established sales channels in the professional, 
centralised hospital laboratory testing market in 
the UK and France. Coris, based in Gembloux, 
Belgium, develops, manufactures and markets 
rapid diagnostic test kits, mainly lateral flow tests, 
for use by healthcare professionals. Coris is ISO 
13485 certified and markets its products through 
distributors in Europe, Asia, South America, Africa 
and Oceania.
In the highly competitive diagnostics market, Avacta’s 
proprietary Affimer® platform is able to differentiate 
our immunodiagnostic products to gain competitive 
advantage and grow market share.

Therapeutics Division
The Avacta pre|CISIONTM platform is a proprietary 
warhead delivery system based on a tumour-specific 
protease that is designed to concentrate highly potent 
warheads in the tumour microenvironment while 
sparing normal tissues. Fibroblast activation protein-α 
('FAP') is an extracellular post-proline protease that is 
upregulated in many solid tumours in a membrane-
bound form on cancer associated fibroblasts as well 
as tumour cells. FAP activity is also observed as a 
soluble protease to a low degree in plasma. 
A pre|CISIONTM molecule has two key properties: 
1.	 It prevents the warhead from entering cells. 
2.	 It is specifically cleaved by FAP to release active 
warhead in the tumour. 
The peptide moiety linker, pre|CISION™, prevents 
cellular entry of the warhead unless it is cleaved by 
FAP, thus enabling targeted delivery of the warhead to 
tumours.
The lead pre|CISIONTM programme, AVA6000 a tumour 
activated form of doxorubicin, is in Phase 1 studies 
and has achieved clinical proof-of-concept, showing 
dramatic improvement in safety compared with 
standard doxorubicin, and early signs of clinical activity. 
Affimer® is a novel biologic platform which has 
significant technical and commercial advantages 
compared with antibodies and is used both to 
develop advanced immunotherapies and to improve 
the performance of immunodiagnostics. 
AVA6000 FAPα-activated doxorubicin - the lead 
pre|CISION™ programme
Avacta’s lead programme, AVA6000, is a pre|CISIONTM 
targeted form of doxorubicin, an anthracycline that 
is used as part of standard of care in several tumour 
types including soft tissue sarcoma. Its dosing 
schedule and long-term use is limited by severe 
systemic toxicities, in particular, by haematological 
toxicities and cardiotoxicities. 
The ALS-6000-101 Phase 1 clinical trial involves a 
dose-escalation Phase 1 study in patients with locally 
advanced or metastatic solid tumour, known to be 
Fibroblast Activation Protein α ('FAP') positive, in 
which cohorts of patients receive ascending doses 
of AVA6000 initially at three-weekly intervals to 
determine the maximum tolerated dose. For more 
information visit www.clinicaltrials.gov (NCT04969835).
 The Phase 1a three-weekly dose escalation study has 
been carried out at several sites in the UK and US 
and completed the seventh and final dose escalation 
cohort at 385 mg/m2, which is approximately 3.5 times 
the normal dose of doxorubicin. A number of patients 
in several different cohorts remain on the trial. 
The data emerging from the three-weekly dose 
escalation study show an excellent safety profile and 
that the pre|CISIONTM  platform is functioning as 
expected. The key findings of the study are:
•	 The pre|CISIONTM platform targets the release of 
a chemotherapy to the tumour as intended. The 
data show that the pre|CISIONTM modification is 
cleaved specifically by FAP, an enzyme present 
in high concentrations in many solid tumour 
compared with healthy tissue. In the case of 
AVA6000, this targets the release of doxorubicin 
to the tumour microenvironment, concentrating 
the active cytotoxic drug within the tumour 
microenvironment and limiting systemic exposure 
to the chemotherapy.
•	 AVA6000 has significantly improved the safety and 
tolerability of doxorubicin. A significant reduction 
in the frequency and severity of the known 
doxorubicin toxicities has been observed across the 
dosing range. A maximum tolerated dose has not 
been reached in the three-weekly dose escalation 
study despite dosing approximately 3.5x the normal 
level of doxorubicin in the highest and final dose 
cohort in this part of the Phase 1a study.
•	 AVA6000 has shown encouraging preliminary 
clinical signs of anti-tumour activity. Preliminary 
results in the Phase 1a trial demonstrate activity 
of AVA6000 in patients with tumour with high FAP 
activity and anthracycline sensitivity, validating the 
mechanism of action of AVA6000. 
Post-period end the Company announced that 
patients are now being dosed in a two-weekly 
dose escalation study with the aim of defining the 
recommended Phase 2 dose (RP2D), allowing dose 
expansions to begin in H2 2024 followed by the Phase 
2 efficacy study, subject to FDA approval, in a selected 
orphan indication.
 
Avacta Therapeutics Division aims to leverage its two proprietary technology 
platforms, pre|CISION™ and Affimer®, to develop innovative oncology 
therapies that make a significant difference to cancer patients’ treatment 
experience and outcomes.

Pipeline of pre|CISION™ chemotherapies
The next most advanced pre|CISION™ pre-clinical 
candidate is AVA3996, a tumour-activated proteasome 
inhibitor based on an analogue of Velcade.
Avacta is developing other pre|CISION™ drugs 
incorporating more potent toxins, the details of which 
have not yet been made public, but which the Group 
intends to disclose during 2024. 
Affimer® immunotherapy programmes
Avacta has also developed Affimer® immunotherapies, 
the most advanced of which (AVA032) is in pre-
clinical research phase and is a bispecific molecule 
comprising an anti-PD-L1 Affimer® fused to IL-
15, a cytokine that regulates the activation and 
proliferation of immune cells (T-cells and natural killer 
(NK) cells). Data presented at the AACR-NCI-EORTC 
International Conference on Molecular Targets and 
Cancer Therapeutics in October 2023 demonstrate 
encouraging in vitro and in vivo efficacy.  
Translation of the Affimer® platform into the clinic 
to demonstrate the safety and tolerability of this 
novel therapeutic protein platform represents a key 
value inflection point for the Affimer® technology. 
Limited resources for internal Affimer® programmes 
are complemented by external partnerships for the 
Affimer® platform with Daewoong Pharmaceutical 
and LG Chem Life Sciences.

AVA6000 Clinical Trial Update
The pre|CISION™ platform - a proprietary 
warhead delivery system
The Avacta pre|CISIONTM platform is a proprietary 
warhead delivery system based on the activity 
of a cancer-specific protease that is designed to 
concentrate highly potent warheads in the tumour 
microenvironment ('TME') while sparing normal tissues.
Fibroblast activation protein-α ('FAP') is an extracellular 
post-proline protease that is upregulated in many 
solid tumours in a membrane-bound form of cancer 
associated fibroblasts as well as tumour cells. FAP 
activity is also observed as a soluble protease to a low 
degree in plasma.
AVA6000 is the first clinical-stage pre|CISIONTM 
molecule. It is a peptide drug conjugate that 
leverages the tumour-specific expression of FAP 
by linking a peptide moiety which has two key 
properties:
•	 It prevents the warhead from entering cells.
•	 It is specifically cleaved in the tumour 
microenvironment by FAP to release active 
doxorubicin which can then enter cells.
pre|CISIONTM drug conjugate ('PDC')
The warhead is linked to a peptide specifically cleaved 
by fibroblast activation protein-α ('FAP'), thus releasing 
the warhead in the extracellular space of the TME.
The Avacta pre|CISIONTM platform is a proprietary 
warhead delivery system that is designed to 
concentrate highly potent warheads in the tumour 
microenvironment while sparing normal tissues that is

Fibroblast activation protein-α ('FAP') is an extracellular 
post-proline protease that is upregulated in many 
solid tumours in a membrane-bound form on cancer 
associated fibroblasts as well as tumour cells, FAP 
activity is also observed as a soluble protease to a low 
degree in plasma. 
pre|CISION+ Immuno-peptide drug conjugate
The Avacta pre|CISION+ platform is based on the 
peptide drug conjugate delivery model which is 
then conjugated to a biologic protein moiety such 
as the Fc region of an antibody or Affimer XT to 
significantly extend the half-life and optimise the 
pharmacokinetics of the peptide drug conjugate.
Significant extension of the half-life of the 
pre|CISIONTM warhead will benefit certain warheads 
that target tumours in ways other than traditional 
cytotoxics. Examples of such pre|CISION+ warheads 
include cancer pathway targeted therapies or 
immune modulators where more consistent and 
concentrated delivery to the TME is optimal.
Biologic conjugates such as the Fc region of 
monoclonal antibodies are preserved from 
degradation by naturally occurring means within the 
immune system such as antibody recycling by the 
neonatal Fc receptor (Roopenian 2007, Rath 2015).
Delivery of the warhead by a pre|CISION+ drug leverages 
the tumour-specific expression of FAP combined with 
the half-life extension of the biologic conjugation.
pre|CISION-ADC
The Avacta pre|CISION-ADC platform leverages the 
FAP-activated tumour-specific release mechanism 
of the pre|CISIONTM technology with the tumour-
targeting capability of an antibody or Affimer®.
The mechanism of action of the pre|CISION-ADC 
model optimises warhead delivery by targeting the 
warhead to the TME in two ways: with the antibody 
or Affimer® target and FAP-release in the TME.
Optimisation of the bystander effect is a key benefit 
of the mechanism of the pre|CISION-ADC platform. 
The biologic targets the molecule to the TME through 
a non-internalising mechanism and membrane-
bound FAP releases the warhead in the extracellular 
24
Strategic Report

space, thus equally targeting both antigen-positive 
and antigen-negative tumour cells.
The dual-delivery by a pre|CISION-ADC drug 
leveraging both a tumour antigen to target and FAP 
to release the warhead will significantly reduce the 
off-tumour toxicities associated with traditional 
ADC mechanisms. 
Doxorubicin
Doxorubicin is one of the most effective and widely used 
chemotherapeutic agents for the treatment of a broad 
range of solid tumours and haematological malignancies 
including breast, ovarian, soft-tissue sarcoma and 
lymphoma. Nevertheless, the clinical use of doxorubicin 
has been limited because of a significant risk related 
to cardiac damage. The risks of this life-threatening 
side effect depend on cumulative doses and damage 
can occur both acutely and chronically over decades 
after exposure. When doxorubicin is administered 
intravenously into the patient it is readily distributed 
across almost all tissues, resulting in indiscriminative 
toxic effects on both healthy and tumour cells. One 
of the most serious side effects of doxorubicin is 
cardiomyopathy, whereby the heart muscle is damaged 
by the toxic effects of the doxorubicin, leading to a loss 
of cells in the heart muscle and ultimately irreversible 
congestive heart failure. The rate of cardiomyopathy is 
dependent on doxorubicin cumulative dose and there 
are several ways in which doxorubicin is believed to 
cause damage to the heart.
How does AVA6000 address the drawbacks 
of doxorubicin? 
Avacta’s lead pre|CISIONTM peptide drug conjugate 
programme, AVA6000, is a tumour-targeted form of 
doxorubicin, an anthracycline that is used to treat 
several indications both as a monotherapy (e.g. for 
advanced soft tissue sarcoma) and in combination with 
other drugs (e.g. for breast cancer). Its dosing schedule 
and long-term use is limited by severe systemic 
toxicities, in particular, by haematological toxicities and 
cardiotoxicities. 
AVA6000 targets the release of doxorubicin to the FAP-
rich tumour tissue thereby reducing the amount that is 
found in the bloodstream of the patients.  This lowers 
the systemic exposure to the drug whilst concentrating 
its release in the tumour and therefore reduces the 
systemic toxicities and the cumulative exposure of the 
heart to doxorubicin.  
This offers the potential to not only increase the dose 
level and frequency of dosing of doxorubicin but 
also allows for an increase in the number of cycles 
of treatment which is currently limited by the risk of 
cumulative heart damage. 
This potential improvement in dosing schedule (dose, 
dose frequency and number of cycles) due to reduced 
toxicities could improve the efficacy of doxorubicin in 
certain tumours and therefore improve the outcomes 
for patients.
AVA6000 clinical trial update
•	 A ‘first-in-human’ (‘FIH’) dose escalation study of 
AVA6000 is currently dosing patients in the UK and 
US (ClinicalTrials.gov Identifier: NCT04969835). 
•	 Safety and tolerability of AVA6000 are being 
assessed in a Phase 1a dose escalation study. Data 
to date from the three-weekly dosing arm of the 
trial demonstrated that the pre|CISIONTM platform 
targets the release of the chemotherapy to the 
tumour as intended, that AVA6000 significantly 
improved the safety and tolerability of doxorubicin 
and that AVA6000 is already showing encouraging 
preliminary clinical signs of anti-tumour activity.
•	 Cohort 7 was the final cohort in the three-weekly 
study and even at this dose level (385 mg/m2), 
which is approximately 3.5x the equivalent standard 
dose of doxorubicin, dose-limiting toxicities were 
not observed and the Safety Data Monitoring 
Committee ('SDMC') has concluded that this dose 
level is safe. A number of patients remain on the 
three-weekly study at this time in several different 
cohorts. A two-weekly dosing safety study has now 
commenced in the US on the basis that this is likely 
to lead to better efficacy.
•	 The combined data from the three-weekly and 
two-weekly studies will provide information to allow 
the Company to define the dose and schedule to 
be used in future efficacy studies. Patients can be 
dosed in parallel in the two-weekly dose escalation 
study and Avacta remains on track to begin the 
dose expansion efficacy study in the second half 
of 2024. The data from the expansion study will 
be used to inform the optimal choice of a single 
orphan indication for the Phase 2 efficacy study 
which will follow on immediately.

AffyXell was established in January 
2020 by Avacta and Daewoong as 
a joint venture to develop novel 
mesenchymal stem cell (‘MSC’) 
therapies. AffyXell combines Avacta's 
Affimer® platform with Daewoong's 
MSC platform such that the stem cells 
are genetically modified to produce 
and secrete therapeutic Affimer® proteins with immuno-modulatory effects in situ 
in the patient. The Affimer® proteins are designed to enhance the therapeutic 
effects of the MSC creating a novel, next generation cell therapy platform. 
Avacta has successfully developed and characterised Affimer® proteins against 
the second target of interest for AffyXell and has filed a patent application for 
the associated intellectual property triggering the second milestone in the 
agreement during the reporting period. The second milestone resulted in an 
increase in Avacta’s shareholding in AffyXell, from 19% to 25%.

Early in 2021, Avacta signed a licensing 
agreement with POINT Biopharma 
Inc. (‘POINT’), to provide access to 
Avacta’s pre|CISION™ technology for 
the development of tumour-activated 
radiopharmaceuticals.
Under the terms of the agreement, Avacta received an upfront fee and will 
receive development milestone payments for the first radiopharmaceutical FAPα-
activated drug totalling $9.5 million. Avacta will also receive milestone payments for 
subsequent radiopharmaceutical FAPα-activated drugs of up to $8 million each, a 
royalty on sales of FAP-activated radiopharmaceuticals by POINT and a percentage 
of any sublicensing income received by POINT.
Avacta is bound by confidentiality clauses in the licensing agreement with POINT 
and is therefore unable to provide a detailed update on progress outside of the 
information that has been placed in the public domain by POINT (POINT has 
named its pre|CISIONTM based programmes CanSeekTM).
POINT’s acquisition by Eli Lilly has not affected the licensing arrangements.

Diagnostics Division
In October 2022 Avacta set out a strategy to grow 
its Diagnostics Division through acquisitions to build 
a stand-alone in vitro diagnostics (‘IVD’) business 
taking advantage of post-pandemic opportunities to 
develop products in-house and to capture proprietary 
routes to market to maximise profitability. The focus 
of the Division is on professional healthcare in both 
the centralised setting such as hospital pathology 
laboratories and the decentralised setting such as 
primary healthcare, clinics and pharmacies. The 
strategy also has the potential to benefit from the 
competitive advantages of the Affimer® platform to 
differentiate immunodiagnostic products, such as 
lateral flow tests, in what is a competitive market. 
Avacta has focused its acquisitions on businesses with 
clear growth opportunities through product portfolio 
or geographic expansion, improved commercial 
processes and partners. 
Avacta has successfully executed two acquisitions 
of businesses that fit with this strategy: Launch 
Diagnostics Ltd (‘Launch’), a leading independent 
distributor of IVDs to the professional, centralised 
hospital laboratory testing market in the UK and 
France, and Coris BioConcept SRL (‘Coris’), a developer 
and supplier of rapid diagnostic test kits, mainly 
lateral flow tests. These acquisitions have allowed the 
Division to build scale and put it on a trajectory to 
become EBITDA positive in the near future.
The Diagnostics Division now has well-established 
routes to market in the UK and France and is 
expanding into other European countries including 
Germany. Alongside third-party products it has a 
market-leading portfolio of AMR test products that 
form part of the clinical workflow in many countries.  
From this base it is possible to build a significant, full 
spectrum, European IVD business through organic 
growth which is likely to be attractive ultimately to 
both strategic and financial acquirers. 
As announced on 28 February 2024, the Avacta Board 
has taken the strategic decision to focus its cash 
resources on growing the Therapeutics Division which 
the Board believes is now the main value driver of the 
Group. Whilst the Diagnostics Division is expected to 
be cash generative in the near future, it is strategically 
important for the Group to simplify its structure in 
order to attract specialist healthcare investors with the 
ability to support the growing pre-clinical and clinical 
pipeline of pre|CISIONTM and Affimer® therapeutics 
and it will do so in a manner which maximises value 
for its shareholders.
Avacta’s Diagnostics Division is focused on supporting healthcare 
professionals and broadening access to high quality diagnostics.

Launch Diagnostics
After Avacta completed the acquisition 
of Launch Diagnostics, the UK’s largest 
independent IVD distributor, Launch has 
provided Avacta with well-established sales 
channels in the professional, centralised 
hospital laboratory testing market in the 
UK and France. 
Avacta’s plan to grow the Launch Diagnostics 
business includes expanding the company’s product 
portfolio and investing in the sales teams in the 
UK and France. However, the most significant 
opportunity for growth lies in the geographical 
expansion of the business into Germany which is 
Europe’s largest diagnostics market. 
Launch Diagnostics provides pathology solutions 
encompassing high-quality diagnostic reagents and 
instrumentation from world-leading manufacturers to 
the health services of the UK, Belgium, Luxembourg 
and France through Launch Diagnostics SAS and to 
the Republic of Ireland. 
Offering an extensive portfolio of diagnostic kits 
and laboratory instrumentation, Launch’s product 
range has expanded over the years to include a 
comprehensive range of enzyme immunoassays (EIA), 
single test devices, serology products, molecular 
assays and instrumentation.
New site
At the end of February 2024, Launch Diagnostics 
moved to new facilities at Crossways Business 
Park in Dartford.  The new office incorporates a 
demonstration laboratory, training room and open 
plan working areas with several collaboration areas, 
where products can be showcased to customers and 
scientific symposia held. 
In addition to the new site, Launch customers in France 
are now benefiting from a French language website 
which was developed and launched in January 2024.  
Sales and marketing activities
The marketing team works closely with suppliers to 
support Launch’s customers. They also introduce new 
products and undertake due diligence to ensure new 
products fit to the needs of customers.  
The sales team are responsible for the customers in 
their territory where strong relationships ensure the 
business stays up to date with the requirements of 
the NHS and other customers, as well as being able 
to discuss new assays and equipment introduced into 
the product portfolio.   This approach has enabled a 
year-on-year sales growth of all key product ranges.
Advertising in scientific journals, trade conferences 
and sponsoring scientific meetings are all part of 
the strategy to promote key products. In September 
2023 Launch won the ‘Best Stand Award’ at the IBMS 
Congress for a sustainability themed stand, which 
used recycled pallets to build the main wall, recycled 
cardboard signage and living plants.  The stand was 
also made to be re-usable. 
Awards and recognition
Launch has also received a Bronze Award for 
the second year running for sales from Dynex 
technologies, suppliers of the DS2 automated ELISA 
platform.  In addition, Launch received an award from 
Vircell for Best distributor by sales volume for their 
Amplirun range, a series of external controls which 
can be used with molecular assays.
Technical activities
Launch’s technical department remains a pivotal 
function in the business. As the automation 
portfolio grows, due to the rapid change in specialist 
diagnostics, a lot of time is devoted to ensuring 
the team are fully prepared to support customers’ 
advancing needs. Customer service is a priority; 
the focus is to deliver quick, effective, and efficient 
support to customers who are providing laboratory 
services to patients throughout the UK, Ireland, France 
and Belgium. The constant monitoring of performance 
levels across all territories allows the team to 
accurately identify potential issues before they arise, 
resulting in short turnaround time for resolutions.
The Quality and Regulatory department has been kept 
busy due to the ever-changing regulatory landscape 
for the UK and Europe. All the products distributed 
by Launch are market-compliant and the Quality and 
Regulatory department helps us to stay informed of 
new and developing regulations, especially around the 
IVDD and IVDR.

Product Updates
Liofilchem antimicrobial resistance assays and 
culture media
Liofilchem products for antimicrobial resistance (‘AMR’) 
testing have been an area of consistent growth for 
Launch Diagnostics since distribution commenced, with 
sales primarily of MIC testing strips. In 2023 Launch 
expanded their Liofilchem offering to include agar 
plates which optimise the performance of Liofilchem 
MTS strips for antimicrobial resistance monitoring, 
whilst also following the EUCAST European guidelines. 
A number of other Liofilchem AMR products such as 
ComASP microbroth dilution panels are also becoming 
the test of choice for many reference laboratories and 
general microbiology laboratories.
Coris BioConcept AMR test products
Coupled with the success of Liofilchem AMR 
business, Launch has also started to sell products 
from Avacta’s Coris BioConcept business in both 
the UK and France.  The products include a range 
of rapid tests for detecting antibiotic resistance 
mechanisms in bacteria, and complement the 
Liofilchem range, allowing laboratories to screen and 
confirm antimicrobial resistance.  The combination of 
Liofilchem and Coris products will enable Launch to 
grow within the AMR testing business by covering all 
assays required in the current testing guidelines and 
shows the successful integration and growth within 
Avacta’s Diagnostics Division, reflecting the Group’s 
strategy in this area. 
Vircell VirClia Lotus
The new VirClia Lotus from Vircell was launched in July 
2023. This is a chemiluminescence serology analyser 
with more than 90 assays in a monotest format 
including Aspergillus galactomannan antigen, Candida, 
HEV, CMV, TORCH Mycoplasma pneumoniae and 
syphilis antibody. The instrument is ideal for running a 
combination of tests and a stat function allows urgent 
assays to be incorporated as required. The instrument 
allows for continual loading of both reagents and 
samples for added flexibility. The first instrument 
has been placed and a further two are scheduled 
in the coming months. New assays are constantly 
being developed by Vircell, with a VirClia test for 
Helicobacter pylori being released in March 2024.
Anatolia Molecular assays
Following internal verification work, the Bosphore 
Gastroenteritis v3 assay from Anatolia Geneworks 
was launched in July 2023. This assay provides a 
fully comprehensive PCR test for the detection of all 
clinically relevant bacteria, viruses and parasites from 
one test, with a simple workflow and runtime.
HOB
Since the HOB Clia systems for testing auto-immune 
disease were launched to the UK market at the end of 
2022, Launch has installed two instruments, and three 
further instruments are anticipated for placement 
this year. These are currently going through the NHS 
tender procurement process. 
There are two instruments in the HOB range, the 
BioClia 6500 and the BioClia 500, and therefore 
laboratory workload can determine the best 
instrument based on the sample numbers and 
required throughput. The instruments can run 
multiple assays at the same time, which aids in the 
laboratory workflow.

Biosystems A15s
The Biosystems A15s analyser can test for 
Calprotectin and Faecal Occult Blood (FOB) using an 
immunoturbidimetric method.  Since its introduction 
to the UK market, there has been a lot of interest 
for this system both in the UK and ROI. There are 
currently four laboratories completing validation work 
and another four about to start evaluations.   
Traditionally, sample processing for both the 
Calprotectin and FOB assays is time consuming with 
multiple steps, but the Biosystem A15s method uses 
a dedicated sample collection tube that requires no 
special pre-treatment, and reduces the laboratory 
sample preparation time.
Gold Standard Diagnostics AIX1000
The AIX1000 is a dedicated analyser and assay for testing 
syphilis by the Rapid Plasma Reagin (‘RPR’) method.  
Syphilis case in both the UK and France have increased 
dramatically in the last few years and traditional manual 
testing is time consuming and subjective.
The AIX1000 from Gold Standard allows for the 
automatic processing, dilution, testing and reading 
of results by a modified RPR method. Since its launch, 
the instrument and assay have been placed in both 
the UK and France within public laboratories and 
reference centres.  
FlashDx
The FlashDx molecular analyser and assays were 
launched for sale in Belgium in Q3 of 2023. This 
is a plug-and-play instrument with a small range 
of multiplexed nucleic acid microbiology tests, 
covering respiratory diseases, SARS CoV and sexually 
transmitted diseases. Each assay can detect the DNA 
from more than one organism. 
Sustainability 
Launch Diagnostics is committed to the principles 
of sustainability and a sustainability policy has been 
implemented as a central tenet of all operations. This 
covers environmental, social, and economic aspects 
together with the health, safety and well-being of all 
employees and visitors.
A carbon reduction plan is in place and there is a 
commitment to achieving net zero emissions by 2050, 
which is in line with the NHS net zero roadmap. This 
is also aligned with the requirements of the British in 
vitro diagnostics association (‘BIVDA’).

Coris, based in Gembloux, Belgium, was established 
in 1996 and specialises in developing, manufacturing 
and marketing rapid diagnostic kits for the detection 
of human respiratory, gastro-enteric and blood-
borne pathogens and for the detection of antibiotic 
resistance markers (RESIST range). These tests are 
based on the lateral flow immunochromatography 
technology with colloidal gold particles or latex 
microspheres and are CE marked for professional use. 
Coris is ISO 13485 certified and markets its products 
through distributors in Europe, Asia, South America, 
Africa and Oceania. 
Operationally, Coris employs 35 members of staff 
split across production, sales, marketing, quality 
control, regulation and administration. In March 
2023, the business entered into a nine-year lease of 
a new 10,700 ft2 production, offices and warehouse 
facility in Gembloux. 
Coris’ product portfolio comprises diagnostic tests 
for respiratory, gastro-enteric and blood-borne 
pathogens (bacteria, viruses and parasites) and for the 
detection of antibiotic resistance markers. Antibiotic 
resistance is a major global challenge and there are 
good future growth prospects for the market  
for antimicrobial resistance (‘AMR’) testing and is a key 
area in which Avacta expects to grow the Coris business. 
Research and innovation are at the core of Coris, with 
R&D activities producing a history of world firsts:
•	 Coris produced the first lateral flow test for 
the detection of Rotavirus, in 1997, quickly 
followed by other products for the diagnosis of 
gastroenterological and respiratory diseases. Other 
tests allowing the detection of chemical molecules 
in urine are also part of the catalogue, as well as 
several molecular biology tests from European

•	 Coris produced the first lateral flow test for 
the detection of carbapenemase-producing 
enterobacteria (CPE) in 2015. This range has been 
enriched with tests specific to Acinetobacters and 
for the detection of extended spectrum beta-
lactamase (ESBL). 
•	 Coris was one of the first two companies, and the 
first in Europe, to offer a Covid-19 diagnostic test.
Coris BioConcept
In May 2023, Avacta completed the acquisition 
of Belgian diagnostics business Coris BioConcept.
36
Strategic Report

All Coris’ diagnostic products are intended to be sold to 
medical analysis laboratories (both public and private), 
with the sales taking place mainly via a network of 
distributors present in more than 70 countries, who 
are regularly trained in the new products offered. The 
presence of the sales teams at various international 
congresses and exhibitions ensures product visibility 
among new distributors and customers.
Recently, to meet the growing demand for antibiotic 
resistance assays Coris has invested in a fully 
automated production line. In addition Coris has 
strengthened the production and sales teams as 
well as the team responsible for certifications and 
registrations to speed up the market approval of new 
products already underway in R&D.
Coris is also now exploring new markets including 
the US and lower-income countries such as India in 
which a new business model is being tested. In this 
new model, Coris will produce and provide the basic 
nitrocellulose test strips and other components for 
its products to a third party manufacturer/distributor 
in the country who will assemble product kits at a 
lower overall costs than can be achieved in Europe 
that is more suitable for the local market. In this way 
Coris plans to grow its global coverage for its market-
leading AMR products.
To date, Coris has been involved in more than 30 
international projects including 18 EC-funded projects 
and a wide range of Belgian collaborative projects. 
These projects have resulted in patents, publications 
and commercialised products, all manufactured 
since 2023 in a new facility located in Gembloux, 
Belgium. Coris also provides services for custom test 
development and contract manufacturing.

Avacta Report and Accounts          2023

Revenue
Reported Group revenues for the year ended 
31 December 2023 increased to £23.25 million 
compared to £9.65 million for the year ended 31 
December 2022 (‘2022’). 
Revenues for the Therapeutics Division were £2.06 million 
(2022: £5.48 million), with the achievement of a further 
milestone in the collaboration with AffyXell (realised in additional 
equity in the joint venture). The reduction from the prior year is 
because milestones were received from both AffyXell and  
LG Chem in 2022. 
Revenues for the Diagnostics Division were £21.19 million 
(2022: £4.17 million). This significant increase reflects both a 
full year impact of Launch Diagnostics (acquired in October 
2022), contributing £17.87 million, and the acquisition of Coris 
BioConcept in May 2023, contributing £3.27 million in the post-
acquisition period. On a like-for-like annualised basis, revenues 
of the acquired businesses grew by approximately 10% in 2023.
Acquisitions
On 31 May 2023, the Group acquired 100% of the shares and 
voting interests in Coris BioConcept SRL. Coris, established in 
1996, develops, manufactures and markets rapid diagnostic 
test kits, mainly lateral flow tests, for use by healthcare 
professionals. Coris is ISO13485 certified and markets its 
products through distributors in Europe, Asia, South America, 
Africa and Oceania. Total consideration for Coris included 
an initial consideration of £7.31 million in cash payable upon 
completion of the acquisition, in addition to £2.80 million 
for other short-term non-operating assets and an additional 
deferred earn-out element. The earn-out element provides 
additional consideration of 100% of the revenue achieved in 
excess of €5.5 million for the year ended 31 December 2023, 
and 90% of the revenue achieved in excess of €6.5 million for 
the year ended 31 December 2024, with the total earn-out 
payment capped at €3.5 million. The additional consideration to 
be paid based on future gross margin was estimated to be £nil 
at 31 December 2023. 
The acquisition of Coris is part of building critical mass in 
the Group’s Diagnostics Division, which is aiming to build an 
integrated and differentiated IVD business with a global reach 
serving healthcare professionals.
For the period from acquisition to 31 December 2023, Coris 
contributed revenue of £3.27 million and a reported loss of 
£0.28 million to the Group’s results. Further details on the 
acquisition are provided in Note 26 to the Financial Statements.
Research costs
During the year, the Group expensed through the income 
statement £14.53 million (2022: £11.10 million) research 
costs relating to the preCISIONTM and Affimer® therapeutic 
programmes, which are expensed given their early stage in 
the development pathway, in addition to the expansion and 
enhancement of the Group’s existing diagnostic test offering. 
Selling, general and administrative expenses
Administrative expenses have increased during the year to 
£16.86 million (2022: £11.23 million). This reflects a full year of 
Launch Diagnostics, £6.89 million, and the acquisition of Coris, 
£1.13 million. 
Amortisation and impairment expense
Amortisation charges of £1.03 million (2022: £1.05 million) 
have been recognised in the period, with a full year of 
amortisation recognised on acquired intangible assets arising 
from the Launch acquisition, £0.84 million, and amortisation 
of Coris acquired intangible assets, £0.16 million. The 2022 
amortisation expense, £0.82 million, was recognised on Affimer® 
development costs that were fully impaired in the prior period. 
Share of loss of associate
The share of loss of associate of £0.85 million (2022: £1.15 
million) arises from the Group’s equity-accounted investment 
in AffyXell Therapeutics Co., Ltd. The share of losses reflects 
the Group’s 25% ownership share of the losses accumulated 
in the year. The Group investment increased from 19% to 25% 
at 31 December 2023 as a result of additional equity issued 
due to the Group achieving its second technical milestone for 
the collaboration.
Share-based payment expense
The non-cash charge for the year decreased to £2.91 million 
(2022: £7.49 million), due to a limited number of new options 
being issued in the prior year, and the prior year charge being 
increased by changes to the assumptions around the likelihood 
of vesting of options.
Convertible bond
In October 2022, the Group issued senior unsecured 
convertible bonds (‘the Bonds’) of £55.00 million to a fund 
advised by Heights Capital Ireland LLC, a global equity and 
equity-linked focused investor. The Bonds were issued at 95% 
par value with total net proceeds of £52.25 million and accrue 
interest at an annual rate of 6.5% payable quarterly in arrears.
The Bonds contain various conversion and redemption features. 
The Bonds have a maturity of five years, and are repayable in 
20 quarterly amortisation repayments, of principal and interest 
over the five-year term, in either cash or in new ordinary shares 
at the Group’s option. The bondholder also has the option 
Financial Review
38
Strategic Report

to convert Bonds in full outside of the usual quarterly 
amortisation repayments. This has occurred twice during 
the period with a total principal amount converted of 
£3.7 million. For all repayments to date, the Group has 
elected to settle through the issue of shares. The share 
price underlying the quarterly amortisation repayment 
is the lower of the conversion price (118.75p) or a 10% 
discount to the volume weighted average price (‘VWAP’) 
in the five- or ten-day trading period prior to conversion 
date. For other conversions, shares are issued at the 
conversion price, which may reset downwards at 18 
months depending on share price performance, subject 
to a reset price floor of £0.95. 
The bond agreement contains embedded derivatives 
in conjunction with an ordinary host debt liability. The 
derivative element is measured at fair value using a 
Monte-Carlo option pricing model, which estimates the 
fair value based on the probability-weighted present value 
of expected future investment returns, considering each 
of the possible outcomes available to the bondholders. 
The fair value of the derivative liability has reduced during 
the year to £18.32 million (2022: £39.10 million) as a 
result of fluctuations in the share price during the period 
and a reduction in the principal amount remaining from 
£55.00 million to £40.80 million. This has resulted in a 
gain on revaluation of derivative of £15.68 million (2022: 
charge of £4.10 million).
The host debt liability is measured at amortised cost, 
being adjusted to reflect revisions in estimated cashflows 
arising from early conversion events, resulting in an 
implied interest charge of £14.73 million (2022: £2.61 
million) and a liability at year-end of £16.10 million (2022: 
£18.73 million). The increased interest charge reflects a 
full year charge following the issuance of the bonds in 
October 2022.
Net finance costs
Finance income increased to £0.66 million (2022: £0.09 
million) due to an increase in interest rates and a higher 
average cash balance during the year following the 
fundraise in October 2022.
Other finance costs of £0.57 million (2022: £0.01 million) 
relate primarily to IFRS 16 interest charges.
Losses before taxation
Losses before taxation from continuing operations for the 
year were £27.32 million (2022: £41.64 million).
Taxation
The taxation credit has decreased to £2.37 million (2022, 
restated: £4.66 million). The Group claims each year 
for research and development tax credits and, since it 
is currently loss-making, elects to surrender these tax 
credits for a cash rebate, resulting in a credit of £2.05 
million (2022: £2.23 million). The larger credit in the prior 
year reflects the recognition of a previously unrecognised 
deferred tax asset of £2.56 million in relation to tax 
losses, on acquisition of Launch Diagnostics. 
Loss for the period
The reported loss for the period was £24.95 million (2022, 
restated: £36.63 million). The loss per ordinary share 
reduced to 9.15p (2022, restated: 14.34p) based on a 
weighted average number of shares in issue during the 
period of 272,683,485 (2022: 255,369,066).
Cash flow
The Group reported cash and cash equivalent balances of 
£16.63 million at 31 December 2023 (2022: £41.78 million). 
Operating cash outflows from operations amounted to 
£21.85 million (2022: £15.95 million).
During the year, research and development tax credit 
cash rebates were received in relation to the years ending 
31 December 2022 and 2021, resulting in a cash inflow of 
£6.63 million from income tax received (2022: £0.17m paid). 
Net cash outflow from investing activities amounted to 
£9.00 million (2022: £25.04 million) arising principally 
from the acquisition of Coris, an outflow of £6.93 million 
net of cash acquired. In 2022, the acquisition of Launch 
resulted in an outflow of £24.88 million net of cash 
acquired. Other investing cash outflows include purchase 
of property, plant and equipment of £1.12 million (2022: 
£0.56 million).
There was a net cash outflow from financing activities 
of £1.30 million (2022: inflow of £56.90 million), arising 
primarily from the principal elements of lease payments 
of £1.45 million (2022: £0.80 million). In the prior period, 
the inflow arose from the proceeds of issue of share 
capital, £9.02 million, and the issue of convertible 
bonds, £52.25 million, in October 2022. There were also 
proceeds from the exercise of share options of £0.40 
million (2022: £0.47 million).
Financial position
Net assets as at 31 December 2023 were £21.80 
million (2022, restated: £21.00 million) of which cash 
and cash equivalents amounted to £16.63 million 
(2022: £41.78 million). 
The IFRS 16 Leases presentation results in the 
recognition of right-of-use asset amounting to £7.07 
million (2022: £5.42 million) in relation to the Group’s

leasehold properties and other leased assets, together with 
a corresponding lease liability of £7.03 million (2022: £5.11 
million) with the increase arising due to the acquisition of Coris.
Intangible assets increased to £30.84 million (2022: £26.32 
million) due to the acquisition of Coris and the recognition of 
£2.82 million of goodwill. Further details on the acquisition 
accounting are detailed in Note 26 to the Financial Statements.
Liabilities in relation to the convertible bond have been 
recognised with £18.32 million (2022: £39.10 million) relating to 
the fair value of the derivative element at 31 December 2023 
and £16.10 million (2022: £18.73 million) relating to the debt 
liability element. 
Dividends
No dividends have been proposed for the year ended 31 
December 2023 (2022: £nil).
Key performance indicators
At this stage of the Group’s development, the non-financial key 
performance indicators focus on two areas:
•	 The progression of the preCISIONTM and Affimer® 
technologies into clinical stage assets within the 
Therapeutics Division.
•	 The integration of the acquired Diagnostics businesses, 
Launch and Coris, together with expansion into further 
markets with existing and new products.
These are discussed in more detail within the Operational 
Review on pages 16 to 37.
The financial key performance indicators focus around three 
areas, which allow an assessment of the performance of 
the businesses as the Diagnostics Division moves towards 
profitability, and of the funding available as the Therapeutics 
Division technologies progress into clinical stage assets.
•	 Group revenues
•	 Adjusted EBITDA
•	 Cash and cash equivalent balances

Principal risks and uncertainties
The principal risks and uncertainties facing the Group are set 
out on pages 42 to 44.
Cautionary statement
The Strategic Report, containing the Operational and Financial 
reviews of the Group, contains forward-looking statements that 
are subject to risk factors associated with, amongst other things, 
economic and business circumstances occurring from time 
to time within the markets in which the Group operates. The 
expectations expressed within these statements are believed 
to be reasonable but could be affected by a wide variety of 
variables outside of the Group’s control. These variables could 
cause the results to differ materially from current expectations. 
The forward-looking statements reflect the knowledge and 
information available at the time of preparation.
The Strategic Report uses Alternative Performance Measures 
(‘APMs’) to assist in presenting information in this Report in an 
easily analysable and comparable form. The APMs used provide 
a meaningful basis on which to analyse the Group’s financial 
performance, which is helpful to the reader; however, it is noted 
that they are not substitutes for IFRS measures and may not be 
directly comparable to similarly titled measures used by other 
companies. APMs are defined in Note 1(N) to the accounts.
Section 172(1) statement
Section 172(1) of the Companies Act 2006 requires a Director of 
a company to act in the way he or she considers, in good faith, 
would be most likely to promote the success of the company 
for the benefit of its members as a whole. In doing so, s172(1) 
requires the Directors to have regard, amongst other matters, 
to the:
•	 likely consequences of any decision in the long term; 
•	 interests of the Group’s employees; 
•	 need to foster the Group’s business relationships with 
suppliers, customers and others; 
•	 impact of the Group’s operations on the community and the 
environment; 
•	 desirability of the Group in maintaining a reputation for high 
standards of business conduct; and 
•	 need to act fairly between members of the Group. 
In discharging its Section 172(1) duties, the Board has regard to the 
factors set out above and ensures that decision-making processes 
are made on a consistent basis and meet the above factors. 
Key decisions taken by the Board during the year include:
•	 the strategic development and progress of the Group’s lead 
clinical asset, AVA6000 through Phase 1 clinical trials;
•	 the appointment of Shaun Chilton as a Non-executive 
Director to the Board, bringing with him a wealth of 
pharmaceutical and pharmaceutical services experience 
from global companies across Europe and the US to 
support the Diagnostics Division as it progresses with its 
growth strategy; and
•	 the acquisition of Coris BioConcept as part of the strategic 
development of the Diagnostics Division into a European 
IVD business providing innovative solutions to healthcare 
professionals.
The Board looks to promote the long-term success of the 
Group whilst considering the interests of all stakeholders. The 
Board reviews matters relating to financial and operational 
performance; business strategy; key risks; stakeholder-related 
matters; legal and regulatory compliance matters over the 
course of the financial year and through future financial periods. 
The Board members have had refresher training with their 
Nominated Advisor (‘NOMAD’) on Director responsibilities in the 
application of AIM rules.
The Directors work across all the Group’s facilities and provide 
regular updates to employees, most of whom are either 
shareholders or holders of share options, on the progress 
of the Group. The updates provide details of the business 
objectives, strategy and business model, together with sharing 
of technical progress across the various teams within the 
Group. The Directors actively seek regular feedback from 
employees to ensure their interests are reflected.
Engaging with the Group’s stakeholders is key to the way the 
Group is operated and is an important consideration for the 
Directors when making relevant decisions. Details of how the 
Directors engage with stakeholders is set out in the Corporate 
Governance report on pages 53 to 59, including the Group’s 
responsibilities to health, safety and environmental issues 
in relation to its employees, suppliers, customers and the 
communities in which the Group operates.
The Directors believe strongly in maintaining the highest 
levels of business conduct, accountability and good corporate 
governance to all the Group’s stakeholders. In maintaining this 
approach, the Group has adopted the Quoted Companies 
Alliance Corporate Governance Code, with further details on 
how it complies with the Code set out on page 53.

Avacta Report and Accounts          2023

The Board is responsible for risk management and 
reviewing the internal control systems. The internal 
control systems are designed to manage rather than 
eliminate the risk of failure to achieve business objectives 
and can only provide reasonable and not absolute 
assurance against material misstatement or loss. 
The Group highlights potential financial and non-financial 
risks that may impact on the business as part of the 
risk management procedures in the form of a Risks and 
Uncertainties Register. The Board reviews these reports and 
monitors the position at Audit Committee and Board meetings. 
There are ongoing processes for identifying, evaluating and 
mitigating the significant risks faced by the Group, which are 
reviewed on a periodic basis. The review process involves a 
review of each area of the business to identify material risks 
and the controls in place to manage these risks. The process is 
undertaken by the Chief Financial Officer and senior managers 
with responsibility for specific controls. The commercial, 
operational, development and quality teams, in addition to 
project teams, meet on a periodic basis to review progress 
of all key projects and identify key issues for discussion with 
Senior Management. Where any significant weakness or failing 
is identified, implementation of appropriate remedial action is 
completed following approval by the Board.
The principal risks and uncertainties that could have 
a significant impact on the Group are set out here:
Reliance on third parties supporting clinical and 
pre-clinical programmes - Therapeutics	
    Change  ^
Avacta relies heavily upon other parties (including clinical 
research organisations) for many important stages of its 
therapeutic development programmes, including execution 
of some pre-clinical studies and later-stage development 
for its compounds and drug candidates, and management 
of its clinical trials, including medical monitoring and data 
management. Underperformance by any of these other parties 
could adversely impact the Group’s ability to operate effectively.
With the Group now progressing Phase 1 trials on its first 
clinical programme (AVA6000) relationships are established with 
clinical stage third parties (including the recent appointment of 
a specialist clinical CRO to support the AVA6000 trial) which has 
enabled the reduction in the number of third party consultants.
The regulatory approval processes of the MHRA and FDA and 
other comparable regulatory authorities can be lengthy and 
time consuming. The Group consults, where appropriate, with 
regulatory advisers and regulatory-approved bodies to ensure 
that all regulatory requirements are met with timely approvals.
The Group uses experienced and reputable clinical research 
organisations and requires its clinical and manufacturing 
partners to comply with Good Clinical Practice and Good 
Manufacturing Practice.
Manufacturing and supply - Diagnostics	
    Change  ^
The Group relies on both its own (Coris) and third party 
manufacturers (Launch) for the supply of products. 
The Group’s companies maintain ISO13485 and other 
ISO standard quality systems to ensure that products 
manufacturer by it or supplied to it are of high quality.  
The Group continuously works to expand the range of 
products, including potential replacement products, from 
global suppliers.
Commercial - Diagnostics	 	
    	
    Change < >
The regulatory changes in relation to the IVDR/CE marking 
processes have been deferred by the relevant authorities 
alleviating time pressure for existing Group products to become 
compliant. However, the Coris products which are already on 
the market and those which are developed in the future need 
to go through the IVDR/CE/FDA regulatory processes to ensure 
they remain competitive and approved in the markets they are 
sold in. These processes are dependent on validation data and 
the bandwidth of Notified Bodies and therefore delays in com-
mercialisation are possible. The risk of 'IVDR approved products' 
fast-tracked through Chinese Notified Bodies is a risk that needs 
to be managed and monitored. 
Principal Risks and Uncertainties
42
Strategic Report

Expanding the existing markets and launching new products 
is a key commercial risk. The establishment of Launch 
Diagnostics Germany and set up of commercial operations is a 
key risk for 2024.
Integration and growth - Diagnostics                   Change  ^
The Group has successfully completed two acquisitions in 
2022 and 2023 and is now integrating and growing those 
businesses.
A key risk for the Group lies in ensuring that the anticipated 
growth and synergies can be realised. This is managed by 
experienced senior teams in both Launch and Coris as well as 
at Board level.
Research and development	
                   Change < >
The Group’s research and development activities are focused 
around the pre|CISIONTM and Affimer® technologies in the 
Therapeutics Division.
There is a risk, consistent with similar biotechnology compa-
nies developing new and innovative technology platforms, that 
the scientific results required for specific internal development 
programmes, product development projects, customer-related 
evaluations or third-party collaborations will not be achieved. 
This risk is in specific applications of the pre|CISIONTM or 
Affimer®  technologies rather than in the individual technology 
platform as a whole. 
Positive progress has been made with the pre|CISIONTM 
platform through the AVA6000 phase I clinical trials to date 
and the Therapeutics team continue to progress the Affimer® 
platform in preclinical programmes.
With the Group’s first asset (AVA6000) progressing through 
clinical trials there is a risk that the trials might not be suc-
cessful and that the Group is unable to develop marketable 
products. There is a risk that the clinical trials could lead to 
unanticipated results, which require further development 
leading to time delays. The Group has built an experienced 
and reputable team of clinical advisers who are monitoring the 
outputs of the clinical trials to ensure appropriate decisions 
based on data outcomes are taken at the right time.
Diagnostics development risk has changed given the Coris ac-
quisition which has brought an experienced IVD development 
team into the Group. The focus is now on developing and 
improving IVD solutions, primarily rapid point of care tests, in 
infectious diseases and antimicrobial resistance. There is a risk 
that these products may not achieve the required specification 
to be commercially successful.  Coris develops products under 
the ISO 13485 quality standard in order to manage the risks of 
diagnostics product development. 
 
Funding	                    	
	
	
    Change  ^
The development of the Group’s Affimer® and pre|CISIONTM 
technologies in the Therapeutics Division is resource and cash 
intensive.
As at 31 December 2023, the Group had cash of £16.6 million. 
Subsequent to the year end in March 2024, the Group com-
pleted a £31.1 million fund raise with institutional and private 
shareholders to ensure there was a strong cash runway to 
support the Group’s plans. The fundraise required a significant 
discount to the share price immediately prior to the fundraise 
reflecting the challenging nature of the capital markets. 
Progress in the Group’s Therapeutic programmes may impact 
the timing and ability to raise future funding. 
External market and economic factors, such as the Ukraine 
and Palestine conflicts together with UK recession, may impact 
the timing and amount of future funding available through 
capital markets.
Intellectual property	
                   	
    Change < >
The success of the Group’s pre|CISIONTM and Affimer® 
technology platforms depend on its ability to obtain and 
maintain patent protection for its proprietary technology.
Failure to protect the pre|CISIONTM and Affimer® technology 
platforms, or to obtain patent protection with a scope that is 
sufficiently wide, could significantly impact the Group’s ability 
to commercialise the technology. 
Should the patents be challenged, there could be a 
considerable cost in defending the patent rights, with an 
uncertain outcome.
The Board regularly reviews the patent portfolio and its 
protection. Specialist patent attorneys are engaged to apply 
for and defend intellectual property rights in appropriate 
territories.
Key staff	                   	
	
	
    Change < >
The Group has in place experienced and motivated Senior 
Leadership Teams across the Diagnostics and Therapeutics 
Divisions, together with a significant number of highly skilled 
senior scientists and technical specialists.
Loss of key staff could lead to a delay in the Group’s plans and 
operations.
During the year, the Group has successfully recruited, where 
required, senior specialist roles within the Therapeutics 
Division covering scientific, regulatory and clinical development 
areas, having relocated its operations from Cambridge to 
London during 2022.

Avacta Report and Accounts          2023

Strategic Report
Key staff	(continued)
The Group aims to provide remuneration packages, including 
share incentive plans, and working conditions that will 
attract and retain staff of the required level, informally 
benchmarking the level of benefits provided to its staff 
against comparator companies.
Cybersecurity	
                   	
	
    Change < >
Unexpected events such as failures of IT systems or the 
increasing threat of targeted cyber attacks could disrupt the 
Group’s operations from any of its sites or lead to a loss of data. 
The Group continues to place reliance on third-party cloud-
hosted applications, which provide cost-effective services with 
significant redundancies and disaster prevention and recovery 
strategies.
The Group has in place disaster recovery plans which are 
periodically tested, and third-party specialists are used to assess 
any potential vulnerabilities in the Group’s systems.
The Group ensures that all software and systems are regularly 
updated to latest software versions and firmware updates. Its 
cyber security plans and security access levels are reviewed 
on a regular basis, including the two acquisitions within the 
Diagnostics Division, to ensure comparable levels of security 
are in place. It also provides training to staff on dealing with 
potential cyber attacks and security risks.
Loss of facilities	
                  	
	
 Change < >
Should the Group’s facilities become inaccessible through 
damage caused by fire, flooding or theft, the ability to carry on 
development programmes and meet customer deadlines may 
be affected depending on the severity of the incident.
The Group has purpose-built facilities in the UK and Europe 
with specialist equipment and working environments that 
potentially may not be easily repaired or replaced. 
The Group has established business continuity plans in place 
for each location which are regularly reviewed and tested. 
Resilience exists between sites so that certain operations 
could be quickly transferred from one facility to another where 
appropriate. Health and safety procedures and policies exist 
for each site with routine checks on facilities, equipment and 
infrastructure. The Group also maintains adequate insurance 
to cover any business damage or interruption.

Avacta Report and Accounts          2023
49

Governance
The Directors present their report and the 
audited financial statements for the year 
ended 31 December 2023.
Principal activity
The principal activities of the Group are focused on improving 
healthcare outcomes through targeted cancer treatments and 
diagnostics.
Avacta Therapeutics is a clinical stage oncology biotech division 
harnessing proprietary therapeutic platforms to develop novel, 
highly targeted cancer drugs.
Avacta Diagnostics focuses on supporting healthcare 
professionals and broadening access to diagnostics.
Avacta has two proprietary platforms, pre|CISION™ and Affimer®.
The pre|CISION™ platform is a highly specific substrate 
for fibroblast activation protein (FAP) which is upregulated 
in most solid tumours compared with healthy tissues. The 
pre|CISION™ platform harnesses this tumour specific 
protease to activate pre|CISION™ peptide drug conjugates 
and pre|CISION™ antibody/Affimer® drug conjugates in the 
tumour microenvironment, reducing systemic exposure and 
toxicity, allowing dosing to be optimised to deliver the best 
outcomes for patients.
The lead pre|CISION™ programme AVA6000, a peptide drug 
conjugate form of doxorubicin, is in Phase 1 studies. It has 
shown a dramatic improvement in safety and tolerability in 
clinical trials to date compared with standard doxorubicin and 
preliminary signs of clinical activity in multiple patients.
Business review and future developments
A review of the Group’s operations and future developments is 
covered in the Strategic Report on pages 16 to 37. This report 
includes sections on strategy and markets and considers key 
risks and key performance indicators.
Financial results
Details of the Group’s financial results, including events 
after the end of the reporting period, are set out in the 
Consolidated Statement of Profit or Loss and other 
components on pages 81 to 133. 
The Directors have reviewed the results for the years ended 
31 December 2023 and 31 December 2022, including the 
Annual Report & Accounts, preliminary results statement 
and the report from the external auditor. In reviewing the 
statements and determining whether they were fair, balanced 
and understandable, the Directors considered the work and 
recommendations of management as well as the report from 
the external auditor.
Financial key performance indicators (‘KPIs’)
A review of the Group’s KPIs are included within the Financial 
Review on page 40.
Dividends
The Directors do not recommend the payment of a dividend 
(2022: £nil).
Going concern
These financial statements have been prepared on a going 
concern basis, notwithstanding a loss of £24.95 million and 
operating cash outflows from operations of £21.8 million for 
the year ended 31 December 2023. The Directors consider 
this to be appropriate for the following reasons.
The Directors have prepared detailed cash flow forecasts that 
extend to at least twelve months from the date of approval of 
the financial statements. The forecasts take into account the 
Directors’ views of current and future economic conditions 
that are expected to prevail over the period. These forecasts 
include assumptions regarding the status of therapeutic 
development collaborations, the AVA6000 clinical trials, 
product development projects together with the Launch and 
Coris sales pipelines, future revenues and costs, together with 
various scenarios which reflect growth plans, opportunities, 
risks and mitigating actions. The forecasts also include 
assumptions regarding the timing and quantum of investment 
in the therapeutic development programmes. 
Whilst there are inherent uncertainties regarding the 
cash flows associated with the development of both the 
therapeutic platforms, the Directors are satisfied that there 
is sufficient discretion and control as to the timing and 
quantum of cash outflows to ensure that the Company and 
Group are able to meet their liabilities as they fall due for at 
least twelve months from the date of approval of the financial 
statements. The key factors considered in reaching this 
conclusion are summarised below:
•	 As at 31 December 2023, the Group’s cash and cash 
equivalents were £16.6 million (2022: £41.8 million).
•	 The Group completed an equity fundraise in March 2024, 
which raised gross proceeds of £31.1 million (£29.4 million 
net proceeds).
•	 While the Group does have external borrowings in the form 
of a convertible bond with principal amount remaining of 
£40.8 million, this liability can be settled by the issue of new 
equity, rather than cash, at the discretion of the Group. 
•	 The Directors have considered the position of the individual 
trading companies in the Group to ensure that these 
companies are also in a position to continue to meet their 
obligations as they fall due.  
The Directors continue to explore additional sources of 
income and finance available to the Group to continue the 
development of the therapeutic platforms beyond 2024. 
The sources of income could come through the licensing of 
assets/targets from the proprietary Affimer® and pre|CISION™ 
platforms or through additional therapeutic collaborations, 
similar to the LG Chem and Daewoong collaborations, which 
may include up-front technology access fees and significant 
early-stage development income, or through additional 
equity fundraises.
Directors’ Report
50

Avacta Report and Accounts          2023
Based on these indications, the Directors are confident that 
the Company will have sufficient funds to continue to meet its 
liabilities as they fall due for at least twelve months from the 
date of approval of the financial statements and therefore have 
prepared the financial statements on a going concern basis.
Directors
The Directors who were in office during the year and up to 
the date of signing the Report and Accounts, unless otherwise 
stated were:

AGM resolutions were sent with the 2023 AGM Notice to 
shareholders. Shaun’s appointment subsequently ceased at 
the 2023 AGM and he was re-appointed following the 2023 
AGM by the Directors under their powers within the Articles 
of Association. He will therefore be subject to re-appointment 
by shareholders at the 2024 AGM. All four Directors, being 
eligible, offer themselves for re-election. In relation to the re-
elections of each of the Directors, the Board is satisfied that 
the four Directors continue to be effective and to demonstrate

Chairman’s statement on corporate governance
All members of the Board believe strongly in the value 
and importance of good corporate governance and in our 
accountability to all the Company’s stakeholders, including 
shareholders, staff, customers and suppliers. In the statement 
below, we explain our approach to governance, and how the 
Board and its committees operate.
The corporate governance framework which the Company 
operates, including Board leadership and effectiveness, Board 
remuneration, and internal control, is based upon practices 
which the Board believes are proportional to the size, risks, 
complexity and operations of the business and is reflective of 
the Group’s values. The Board adopts the Quoted Companies 
Alliance’s (‘QCA’) Corporate Governance Code for small and 
mid-size quoted companies.
The QCA Code is constructed around ten broad principles 
and a set of disclosures. The QCA has stated what it considers 
to be appropriate arrangements for growing companies and 
asks companies to provide an explanation about how they are 
meeting the principles through the prescribed disclosures.

Governance
Establishing a strategy and business 
model which promotes long-term value 
for shareholders 
Our Mission
Our Mission is to improve patients’ lives and grow shareholder value 
by developing novel cancer therapies and powerful diagnostics 
using our proprietary Affimer® and pre|CISION™ platforms.
Investment opportunity
•	 Avacta has two divisions: A clinical stage oncology biotech 
division harnessing proprietary therapeutic platforms to 
develop novel, highly targeted cancer drugs, and a diagnostics 
division focused on supporting healthcare professionals.
•	 The Therapeutics Division is leveraging Avacta’s proprietary 
technologies to develop innovative oncology drugs that transform 
treatment outcomes to improve cancer patients’ lives.
•	 The Diagnostics Division is focused on supporting healthcare 
professionals and broadening access to testing. 
Technology platforms
•	 Avacta’s has two proprietary platform technologies – the 
Affimer® and pre|CISION™ platforms – which are being used 
to deliver a robust portfolio of products that address multi-
billion dollar markets.
•	 The pre|CISION™ platform is a highly specific substrate 
for fibroblast activation protein (FAP) which is highly 
upregulated in most solid tumours compared with healthy 
tissues. The pre|CISION™ platform harnesses this tumour 
specific protease to activate pre|CISION™ peptide drug 
conjugates and pre|CISION™ antibody drug conjugates 
in the tumour microenvironment, reducing systemic 
exposure and toxicity, allowing dosing to be optimised to 
deliver the best outcomes for patients.
•	 Affimer® molecules are engineered alternatives to 
antibodies that have significant competitive advantages 
including size, stability, versatility, rapid development and 
ease of production.
Therapeutics Division
•	 Avacta Therapeutics’ strategy is to build an in-house pipeline 
of first-in-class and best-in-class targeted cancer therapies 
and immunotherapies, and to accelerate the development of 
its platform technologies by working with partners.
•	 AVA6000, a peptide drug conjugate form of doxorubicin, is 
in Phase 1 studies. It has shown a dramatic improvement in 
safety and tolerability compared with standard doxorubicin 
and preliminary signs of clinical activity.
•	 Data from the Phase I trial for the first candidate, AVA6000, 
confirms the pre|CISIONTM platform’s ability to target a toxin 
to the tumour microenvironment and transform the safety 
profile of such cancer therapies.
•	 The second pre|CISION™ tumour-targeted chemotherapy 
candidate for development was announced in January 2022 
and is a proteasome inhibitor referred to as AVA3996. 
•	 Preclinical data regarding AVA3996, the second pre|CISION™ 
programme, a tumour targeted proteasome inhibitor, were 
presented at the American Association of Cancer Research 
Annual Meeting in April, and at AACR-NCI-EORTC International 
Conference on Molecular Targets and Cancer Therapeutics in 
October along with data from other research programmes.
•	 There is also significant longer-term potential to combine 
the two platforms to create next generation targeted ‘drug 
conjugate’ cancer treatments.
•	 AffyXell Therapeutics ('AffyXell'), the joint venture between 
Avacta and Daewoong Pharmaceutical ('Daewoong') 
continued to progress well with the triggering of a second 
milestone payment, resulting in an increase in Avacta’s 
shareholding in AffyXell to 25% from its previous 19%.
•	 The growing body of clinical and pre-clinical data validating 
the pre|CISIONTM platform has supported an acceleration in 
the Group’s commercial activities including the appointment 
of Dr Simon Bennett as Chief Business Officer of the 
Therapeutics Division. 
Diagnostics Division
•	 Avacta’s Diagnostics Division completed the acquisition 
of Belgium-based Coris BioConcept SRL, a developer and 
manufacturer of rapid tests focused on infectious diseases, 
on 31 May 2023 for an upfront consideration of £7.3 million 
with an earn-out based on future business performance of 
up to £3.0 million payable in cash, adding a broad range of 
marketed professional-use rapid tests to the Division.
•	 The Diagnostics Division, which also includes Launch 
Diagnostics, a leading UK IVD distributor that was acquired 
in October 2022, reports revenue of £21.2 million and an 
adjusted EBITDA loss of £1.2 million.
•	 The Group’s strategy is to divest the Diagnostics Division 
to create a pure-play oncology biopharmaceutical company 
in a manner which maximises value and strategic benefits 
for shareholders.
The Board believes it has a balanced business and capital 
allocation model, and a high-value oncology pipeline supported 
by a revenue-generating, fast-growing diagnostics business, 
which seeks to create long-term shareholder value alongside 
patient benefit.

Avacta Report and Accounts          2023
Board structure, skills and compliance
The Board has a collective responsibility and legal obligation 
to promote the interests of the Company and to define the 
corporate governance arrangements. At 31 December 2023, 
the Board comprised six Non-executive Directors and two 
Executive Directors. Subsequent to the year end, in February 
2024, the composition of the Board changed to five Non-
executive Directors and three Executive Directors. The profiles 
of the Directors are set out on pages 46 to 48.
The division of responsibilities between the Chairman and the 
Chief Executive Officer is clearly defined. The Chairman’s primary 
responsibility is ensuring the effectiveness of the Board and 
setting its agenda. The Chairman is not involved in the day-to-day 
business of the Group. The Chief Executive has direct charge of 
the Group on a day-to-day basis and is accountable to the Board 
for the financial and operational performance of the Group.
The Chairman, Dr Eliot Forster, was appointed as Chairman to 
the Board in June 2018. Prior to his appointment to the Board, 
he was not involved with any part of the Avacta Group and has 
been considered to be independent since his appointment. 
Eliot has significant experience within US and European life 
science companies, in particular in the therapeutics area where 
the Group’s pre|CISION™ and Affimer® technologies have a 
significant focus. Eliot’s time commitment is one to two days 
per month.
The Chief Executive Officer, Dr Alastair Smith, was appointed 
to the Board in September 2007. Alastair has over 15 years’ 
experience as Chief Executive Officer of an AIM-listed business, 
having founded the business and has been responsible for the 
strategic development of the Group, leading fundraising and 
M&A activities during this time. Alastair’s time commitment is 
full time.
Dr Trevor Nicholls was appointed as Non-executive Director in 
August 2013 and was Chairman from August 2013 to June 2018. 
Prior to his appointment to the Board, he was not involved with 
any part of the Avacta Group and has been considered to be 
independent since his appointment. Trevor has vast experience 
with life science and reagents companies and has provided 
significant oversight into the development of the Affimer® 
reagents and diagnostics proposition. During the period Trevor 
has been Chairman of the Remuneration Committee. Trevor’s 
time commitment is one to two days per month. 
Paul Fry was appointed as a Non-executive Director in February 
2020. Prior to his appointment to the Board, he was not involved 
with any part of the Avacta Group and has been considered 
independent since his appointment. Paul has an extensive 
financial background within the life sciences sector and has been 
Chairman of the Audit Committee since his appointment to the 
Board. Paul’s time commitment is one to two days per month.
Dr Mark Goldberg was appointed as a Non-executive Director 
in August 2021. Prior to his appointment to the Board, he was 
not involved with any part of the Avacta Group and has been 
considered independent since his appointment. Mark has 
an extensive background as an Executive and Non-executive 
Director within the US biotechnology sector and is also a 
medical oncologist. Mark’s time commitment is one to two days 
per month.
Shaun Chilton was appointed as a Non-executive Director 
in June 2023. Prior to his appointment to the Board, he was 
not involved with any part of the Avacta Group and has been 
considered independent since his appointment. Shaun has 
held a number of senior and executive commercial positions 
over more than 30 years in companies in pharmaceutical and 
pharmaceutical services industries. Shaun’s time commitment is 
one to two days per month.
Dr Christina Coughlin was appointed as a Non-executive 
Director in March 2022. Prior to her appointment to the Board, 
she was not involved with any part of the Avacta Group and 
was considered independent up to July 2023. In late July 2023 
Christina undertook an additional consulting role to assist the 
Therapeutics Division with the clinical trials of its lead asset, 
AVA6000. This consulting role continued through to the end 
of January 2024, at which point Christina joined Avacta full 
time to become an Executive Director and Head of Research 
and Development. Christina has an extensive background in 
the pharmaceutical and biotechnology fields, with a broad 
background of drug development from pre-IND to filing 
experience in global companies. Christina’s time commitment 
from February 2024 is full time.
Tony Gardiner was appointed as an Executive Director in 
January 2016 and fulfils the role of Chief Financial Officer for the 
Group. Tony has over 25 years’ experience in senior financial and 
operational roles across small and large organisations and has 
previously served as CFO in an AIM-listed business. In addition 
to this role, Tony is also Company Secretary and provides advice 
and guidance to the Board and Non-executive Directors. The 
Board acknowledges that best corporate governance practice 
would not combine the role of an Executive Director and 
Company Secretary; however, given the relative size of the Group 
at this stage, the Board is comfortable with Tony performing both 
roles but will review the position as the Group grows. Tony’s time 
commitment is full time.
The Board met regularly throughout the year, either in person  
or by video conferencing methods, with ad hoc meetings also 
being held. The role of the Board is to provide leadership of the 
Company and to set strategic aims but within a framework of 
prudent and effective controls which enable risk to be managed 
to acceptable levels. The Board has agreed the Schedule of 
Matters reserved for its decision, which includes ensuring that 
the necessary financial and human resources are in place 
to meet its obligations to its shareholders and others. It also 
approves acquisitions and disposals of businesses, major 
capital expenditure, annual financial budgets and recommends 
interim and final dividends. It receives recommendations from 
the Audit Committee in relation to the appointment of an 
auditor, their remuneration and the policy relating to non-
audit services. The Board agrees the framework for Executive 
Directors’ remuneration with the Remuneration Committee 
and determines fees paid to Non-executive Directors. Given 
the relative size of the Company, there is currently no separate 
Nomination Committee and the Board, with advice from 
the Remuneration Committee, takes responsibility for any 
recruitment of Executive and Non-executive Directors, together 
with succession planning. Board papers are circulated before 
Board meetings in sufficient time to allow meaningful review and 
preparation by all Board members.

Governance
Conflicts of interest
Each Director has a duty to avoid situations in which he or 
she has or can have a direct or indirect interest that conflicts, 
or possibly may conflict, with the interests of the Group. 
The Board requires each Director to declare to the Board 
the nature and extent of any direct or indirect interest in a 
proposed transaction or arrangement with the Group and the 
Company Secretary maintains a register of Directors’ other 
interests. The Board has power to authorise any potentially 
conflicting interests that are disclosed by a Director.
Board evaluation and performance
The performance of the Board is evaluated on an ongoing 
basis informally with reference to all aspects of its operation 
including, but not limited to: the appropriateness of its skill 
level; the way its meetings are conducted and administered 
(including the content of those meetings); the effectiveness 
of the various Committees; whether corporate governance 
issues are handled in a satisfactory manner; and whether 
there is a clear strategy and objectives.
A new Director, on appointment, is briefed on the activities 
of the Company. Professional induction training is also given 
as appropriate. The Chairman briefs Non-executive Directors 
on issues arising at Board meetings if required and Non-
executive Directors have access to the Chairman at any 
time. Ongoing training is provided as needed. Directors are 
continually updated on the Group’s business by means of 
Board presentations on risk and compliance matters as well 
as issues covering pensions, social, ethical, environmental and 
health and safety.
In the furtherance of their duties or in relation to acts 
carried out by the Board or the Company, each Director has 
been informed that they are entitled to seek independent 
professional advice at the expense of the Company. The 
Company maintains appropriate cover under a Directors and 
Officers insurance policy in the event of legal action being 
taken against any Director.
Each Director is appraised through the normal appraisal 
process. The Chief Executive is appraised by the Chairman, 
the executive Board members by the Chief Executive and 
the non-executive Board members by the Chairman. Each 
Director has access to the services of the Company Secretary 
if required.
The Non-executive Directors are considered by the Board 
to be independent of management and are free to exercise 
independence of judgement. The Non-executive Directors 
have never been employees of the Company nor do they 
participate in any of the Company’s pension schemes or 
bonus arrangements. They receive no remuneration from 
the Company other than the Directors’ fees. Dr Eliot Forster, 
shortly after his appointment to the Board in 2018, received 
an award of share options, which were equivalent to one 
year’s fee for his services as Chairman. The share options 
which are now fully vested do not carry any performance 
obligations (further details are provided within the 
Remuneration Report). The Board and Company’s advisers do 
not consider the share options, given their relatively low value 
in relation to Dr Forster’s fee for his services and his income 
from other roles outside of the Avacta Group, to impact his 
independence.
Directors are subject to re-election at the Annual General 
Meeting following their appointment. In addition, at each 
Annual General Meeting one third (or whole number more 
than one third) of the Directors will retire by rotation.
As the Group evolves and develops, the composition of the 
Board will change to reflect the priorities of the Group. There 
are currently no ethnic minority Board members; however, 
the Group is satisfied that as further Directors are added to 
the Board that there will be no limitation of opportunities due 
to diversity.

Avacta Report and Accounts          2023
Audit Committee
The Audit Committee (‘the Committee’) is established by 
and is responsible to the Board. 
Paul Fry is the Chair of the Committee and is considered to 
be an independent Non-executive Director. Paul is a member 
of the Chartered Institute of Management Accountants and 
brings significant breadth of recent and relevant financial 
experience to his role, including roles as Chief Financial Officer 
of Argenta and as Chief Financial Officer of Vectura Group 
Ltd, which was listed on the Main Market of the London Stock 
Exchange until it was acquired by Philip Morris International 
Inc. and subsequently de-listed in October 2021. The current 
members of the Committee - Eliot Forster and Trevor Nicholls, 
both of whom are Non-executive Directors - have gained wide 
experience in regulatory, commercial and risk issues. 
The terms of reference of the Audit Committee include the 
following responsibilities:
•	 To monitor and be satisfied with the truth and fairness of 
the Company’s financial statements before submission to 
the Board for approval, ensuring their compliance with the 
appropriate accounting standards, the law and the Listing 
Rules of the Financial Services Authority
•	 To monitor and review the effectiveness of the Company’s 
system of internal control
•	 To make recommendations to the Board in relation to the 
appointment of the external auditor and their remuneration, 
following appointment by the shareholders in the Annual 
General Meeting, and to review and be satisfied with the 
auditor’s independence, objectivity and effectiveness on an 
ongoing basis
•	 To implement the policy relating to any non-audit services 
performed by the external auditor
Risk management
The Board is responsible for risk management and reviewing 
the internal controls systems. The internal control systems are 
designed to manage rather than eliminate the risk of failure to 
achieve business objectives, and can only provide reasonable, 
and not absolute assurance against material misstatement or 
loss. Given the relative size of the Group, there is not currently 
a separate internal audit function.
The Group highlights potential financial and non-financial 
risks which may impact on the business as part of the risk 
management procedures in the form of a Risk Register. The 
Board receives these reports periodically and monitors the 
position at Board meetings. There are ongoing processes for 
identifying, evaluating and mitigating the significant risks faced 
by the Group, which are reviewed on a periodic basis. The 
review process involves a review of each area of the business 
to identify material risks and the controls in place to manage 
these risks given the revenue, production, regulatory and 
supply chain considerations within the Diagnostics Division 
and the clinical trials and pre-clinical development work in the 
Therapeutics Division. The process is undertaken by the Chief 
Financial Officer and senior managers with responsibility for 
specific controls. Where any significant weakness or failing is 
identified, implementation of appropriate remedial action is 
completed following approval by the Board.
The Group maintains appropriate insurance cover in respect 
of actions taken against the Directors because of their roles, 
as well as against material loss or claims against the Group. 
The insured values and type of cover are comprehensively 
reviewed on a periodic basis. 
Remuneration Committee
The Remuneration Committee is chaired by Trevor Nicholls and 
the other current members of the Committee are Eliot Forster 
and Paul Fry, all of whom are Non-executive Directors. The 
Committee meets at least once a year with the Chief Executive 
and Chief Financial Officer in attendance as appropriate.  
The terms of reference of the Remuneration Committee 
include the following responsibilities:
•	 To determine the framework and policy, together with the 
individual packages of the remuneration of the Executive 
Directors and certain other senior executives of the Group
•	 To determine targets for performance-related pay schemes
•	 To review employee benefit structures
•	 To produce an annual report of the Committee’s 
remuneration policy
Shareholder communications and engagement
Responsibility for investor relations sits with the Chief Executive 
Officer, supported by the Chief Financial Officer and Group 
Communications Director together with input from other 
members of the Senior Management Team as required.
The Company is committed to communicating openly with 
its shareholders to ensure that its strategy and performance 
are clearly understood. We communicate with shareholders 
through the Annual Report & Accounts, full-year and half-year 
announcements, trading updates and the Annual General 
Meeting, and we encourage shareholders’ participation 
using technology platforms such as the Investor Meet 
Company platform. 
A range of corporate information (including the Annual Report 
& Accounts) is also available to shareholders, investors and 
the public on our website, www.avacta.com. The Company 
uses intermediaries such as Investor Meet Company and Vox 
Markets to ensure that key updates provided via RNS releases 
are relayed to as many shareholders as possible. The Directors 
encourage the participation of all shareholders, including 
private investors, at the Annual General Meeting, with over 100 
shareholders attending the 2023 AGM in person.
The Chief Executive Officer and Chief Financial Officer meet 
regularly with institutional shareholders to foster a mutual 
understanding of objectives and communicate back to the 
Board. The Chairman and Non-executive Directors are also 
available to discuss governance and other matters directly with 
major shareholders.

Corporate Governance Report (continued)
Shareholder communications and engagement (continued) 
The Company also holds science days, where investors and 
significant shareholders are provided with an update on the 
Group’s scientific activities by members of the Board and 
Senior Management Team.
Share dealing code
The Company has adopted a code on dealings in relation to the 
securities of the Group. The Company requires the Directors 
and other relevant employees of the Group to comply with the 
Share Dealing Code and takes proper and reasonable steps to 
secure their compliance.
Corporate social responsibility
•	 The Board recognises the importance of corporate social 
responsibility and seeks to take account of all of the interests 
of the Group stakeholders, including shareholders, partners, 
employees, customers and suppliers. The Board wants to 
establish and maintain an environment in which employees, 
suppliers and partners act in an ethical and socially responsible 
way in operating the business and the impact of its activities 
relating to health, safety and environmental issues.
Employee welfare and engagement
It is the Group’s policy to involve employees in its progress, 
development and performance. The Executive Directors 
regularly engage with employees, many of whom are 
shareholders or holders of share options, to seek their views 
and provide briefings and presentations on key developments 
and strategy. The updates also follow key events within the 
financial reporting calendar and aim to give staff the same 
level of insight provided to institutional shareholders and 
analysts, providing details of the business objectives, strategy 
and business model, together with sharing of technical 
progress across the various teams within the Group. Senior 
Management work across all the Group’s facilities and actively 
seek regular feedback from staff to ensure that the strategy 
and aims of the Group are readily understood.
Training, career development and promotion of disabled persons
Applications for employment by disabled persons are 
fully considered, bearing in mind the respective aptitudes 
and abilities of the applicants concerned. It is the policy 
of the Group that the training, career development and 
promotion of a disabled person should, as far as possible, 
be identical to that of a person who is fortunate enough not 
to suffer from a disability. In the event of members of staff 
becoming disabled, every effort is made to ensure that their 
employment with the Group continues.
Equal opportunities and diversity
The Group is a committed equal opportunities employer, and 
its employees and job applicants will receive equal treatment 
regardless of age, disability, gender reassignment, marital 
or civil partner status, pregnancy or maternity, race, colour, 
nationality, ethnic or national origin, religion or belief, sex or 
sexual orientation.
The Group does not have formal diversity quotas but 
recognises that a diverse employee profile is fundamental to 
the business. The gender profile across all employees as at 
31 December 2023 was 52% female and 48% male.
Health and safety
The Group has well-defined health and safety policies 
and procedures, complying with current legislation and 
safeguarding staff, contractors and visitors. Alastair Smith 
and Tony Gardiner are the Executive Directors responsible 
for health and safety, chairing Group meetings and reporting 
on health and safety matters to the Board. The Group’s 
policies and procedures form a part of staff induction and 
training programmes. Regular internal safety audits are 
carried out and no significant issues have been identified by 
these audits.
Ethics and compliance
The Group’s Diagnostics and Therapeutics Divisions operate 
around product development, drug development and clinical 
trials where there are highly regulated ethical frameworks 
in place.
Political and charitable donations
The Group does not make political or charitable donations, 
although charitable fundraising by employees is encouraged.
Modern slavery and human trafficking statement
The Group ensures that all employees are eligible to work in 
their country of employment. The majority of our workforce 
are employed directly; however, where agency workers are 
utilised, it is ensured that these same checks are performed 
by the supplier.
The Group has a Whistleblowing Policy, where anyone who 
raise concerns through a defined process, are protected. 
In addition, there are robust policies in place that ensure 
equality amongst colleagues, as well as deploying a zero-
tolerance approach to harassment and bullying in all areas of 
the business.
Environment and greenhouse gas emissions
Due to the nature of the Group’s divisions it has a low 
environmental impact, and seeks to minimise the impact of its 
operations and comply with relevant regulations and legislation.
The Group continues to develop processes to measure 
and report on the Group’s GHG emissions, and provides 
the below voluntary disclosures on Scope 1 & Scope 
2 greenhouse gas (‘GHG’) emissions to aid a better 
understanding of its environmental impact and the measures 
being taken to minimise this.
58

Avacta Report and Accounts          2023
In the table below:
•	 Scope 1 emissions cover direct emissions of GHG from fuel 
combustion
•	 Scope 2 emissions cover emissions from purchased 
electricity
•	 Scope 3 emissions cover all other indirect emissions that 
occur in a company’s value chain. They are not included in 
the reporting below but the Group will continue to develop 
its processes to allow measurement and reporting on these 
emissions in future periods.

The increase in Scope 1 CO2e metric tons in 2023 is largely 
attributable to the inclusion of a full year of emissions data 
relating to Launch Diagnostics, compared with a shorter two 
month period post-acquisition in 2022. These emissions are 
predominantly driven by car fleets of sales representatives and 
field service engineers. Launch Diagnostics is in the process of 
phasing out diesel vehicles in favour of hybrid or fully electric 
vehicles in an effort to reduce its Scope 1 emissions. 
The increase in Scope 2 CO2e metric tons in 2023 is again 
attributable to the inclusion of a full year of emissions data for 
Launch Diagnostics, in addition to seven months of emissions 
post-acquisition for Coris. In the year, Launch Diagnostics 
signed a lease for a new more energy efficient premises, with a 
better EPC rating. The new premises also has electric charging 
points for vehicles to support the change in car fleet.
In addition, the 2023 emissions data also includes reporting 
for Coris BioConcept SRL since its acquisition date. Coris 
installed solar panels at their premises in Gembloux, Belgium 
to help minimise non-renewable energy usage.

authorised for issue on 29 April 2024 and was signed on its 
behalf by:

Audit Committee Report  
Introduction
The Audit Committee is a sub‑committee of the Board and is 
responsible for reviewing all aspects of the financial reporting 
of the business and all aspects of internal control. The 
Committee represents the interests of our shareholders in 
relation to the integrity of information and the effectiveness of 
the audit processes in place.
The terms of reference of the Audit Committee include the 
following responsibilities:
•	 To monitor and be satisfied with the truth and fairness of 
the Company’s financial statements before submission to 
the Board for approval, ensuring their compliance with the 
appropriate accounting standards, the law and the Listing 
Rules of the Financial Services Authority
•	 To monitor and review the effectiveness of the Company’s 
system of internal control
•	 To make recommendations to the Board in relation to the 
appointment of the external auditor and their remuneration, 
following appointment by the shareholders in the Annual 
General Meeting, and to review and be satisfied with the 
auditor’s independence, objectivity and effectiveness on an 
ongoing basis
•	 To implement any policies relating to any non-audit services 
performed by the external auditor
The Committee is authorised by the Board to seek and obtain 
any information it requires from any officer or employee of the 
Company and to obtain external legal or other independent 
professional advice as is deemed necessary by it.
Meetings of the Committee are held as required during the 
year. The regular meetings coincide with the review of the 
scope of the external audit and observations arising from their 
work in relation to internal control and to review the financial 
statements. The external auditor is invited to these meetings 
and meets with the Audit Committee at least once a year. 
At its meeting, the Committee carries out a full review of the 
year-end financial statements and of the audit, using as a basis 
the Report to the Audit Committee prepared by the external 
auditor and considering any significant accounting policies, 
any changes to them and significant estimates or judgements. 
Questions are asked of management of any significant or 
unusual transactions where the accounting treatment could be 
open to different interpretations.
Due to its size and structure, the Group does not have an 
internal audit function. This is a matter which the Committee 
reviews annually.
External auditor
The external auditor is required to give the Committee information 
about policies and processes for maintaining their independence 
and compliance regarding the rotation of audit partners and staff. 
The Committee considers all relationships between the external 
auditor and the Company to ensure that they do not compromise 
the auditor’s judgement or independence, particularly with the 
provision of non-audit services.
BDO LLP were appointed auditor to the Group following a 
tender process in 2021. The Audit Committee considers that 
the Company’s relationship with the Group’s auditor is working 
well and the Committee remains satisfied with the effectiveness 
of the auditor. Piers Harrison retains the role of engagement 
partner. There are no contractual obligations restricting the 
Company’s choice of external auditor.
Significant issues relating to the financial 
statements
The specific issues considered by the Audit Committee in the 
period under review, in relation to the financial statements, are 
shown below.
Use of judgements and estimates
In preparing the consolidated financial statements, the Group 
has made judgements and estimates 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 ongoing basis. Revisions to 
estimates are recognised prospectively.
Information about judgements and estimates made by the 
Group that have the most significant effects on the amounts 
recognised in the financial statements are given below.
Judgements:
During the year, the Committee considered the following key 
judgements made in preparation of the financial statements:
Going concern - The judgement of whether or not the 
accounts should be prepared on a going concern basis, 
as detailed in the Financial Review. The Committee has 
reviewed detailed cash flow forecasts that extend to at least 
twelve months from the date of approval of the financial 
statements. The forecasts take into account the Directors’ 
views of current and future economic conditions that 
are expected to prevail over the period. These forecasts 
include assumptions regarding the status of therapeutic 
development collaborations, the AVA6000 clinical trials, 
product development projects together with the Launch 
and Coris sales pipelines, future revenues and costs, 
together with various scenarios which reflect growth plans, 
opportunities, risks and mitigating actions. The forecasts also 
include assumptions regarding the timing and quantum of 
investment in the therapeutic development programmes.
Whilst there are inherent uncertainties regarding the 
cash flows associated with the development of both the 
therapeutic platforms, the Directors are satisfied that there 
is sufficient discretion and control as to the timing and 
quantum of cash outflows to ensure that the Company and 
Group are able to meet their liabilities as they fall due for at 
least twelve months from the date of approval of the financial 
statements and therefore have prepared the financial 
statements on a going concern basis.
Revenue recognition – Judgements arise from the application 
of IFRS 15 to the Group’s revenue streams, as disclosed in 
Note 1C, as to the timing and nature of revenue recognised 
in relation to the achievement of milestones.
60

Avacta Report and Accounts          2023
Estimates:
The Committee also considered the assumptions and 
estimation uncertainties as at 31 December 2023 that have 
a significant risk of resulting in a material adjustment to the 
carrying amounts and liabilities in the next financial year are: 
Impairment – Impairment tests have been performed on the 
carrying amounts of the Group’s cash-generating units. Key 
assumptions such as the amount and timing of future cash 
flow growth, and the achievement of future development 
milestones, underlie the recoverable amounts used in 
these impairment tests. Further information on the key 
assumptions underlying these tests is disclosed in Note 10.
Acquisitions – Estimation uncertainty is inherent in the 
methods used to determine the fair value of consideration 
and of the assets acquired and liabilities assumed, as set 
out in Note 26. These include the valuation of acquired 
intangible assets and the estimate of deferred contingent 
consideration payable.	
Convertible bond – Determining the fair value of the 
embedded derivative within the convertible bond, both at 
inception and at the reporting date. See Note 22.

Introduction
This report sets out the remuneration policy operated by the 
Company in respect of Executive and Non-executive Directors 
as of the date of the report. The Company is listed on AIM and 
therefore is not required to prepare a remuneration report 
complying with the disclosure requirements under section 
420 of the Companies Act (2006) or the Companies (Directors’ 
Remuneration Policy and Directors’ Remuneration Report) 
Regulations 2019 or to comply with the Financial Conduct 
Authority Listing Rules.
The Company aims to adhere to a high level of compliance 
with corporate governance guidelines and therefore the 
Company has prepared this unaudited report voluntarily so 
that shareholders can clearly understand remuneration paid 
to the Directors. 
At the Company’s Annual General Meeting, a resolution to 
approve the Remuneration Report will be proposed, with 
details provided within the Notice of Meeting. The vote will 
be advisory.
Remuneration Committee
The Remuneration Committee consists of Trevor Nicholls 
(Chairman), Eliot Forster and Paul Fry. All members of the 
Committee are Non-executive Directors of the Company 
and are considered by the Board to be independent. Non-
executive Directors have no personal financial interest in the 
Company, except the holding of shares, no potential conflict 
of interest arising from cross directorships and no day-to-day 
involvement in the running of the Company. The Remuneration 
Committee has responsibility for the following:
•	 Determining the framework and policy, and the individual 
packages of the remuneration of the Executive Directors 
and certain other senior executives, including pension rights 
and any compensation payments
•	 Determining targets for performance-related pay and share 
incentive schemes
•	 Reviewing employee benefit structures
•	 Appointing and using remuneration consultants
•	 Producing an annual report of the Committee’s 
remuneration policy
Remuneration policy of Executive Directors
Avacta’s remuneration policy for Executive Directors is 
designed to attract, retain and motivate executives of 
the highest calibre to ensure that the Group is managed 
successfully for the benefit of shareholders. The policy is 
to pay base salary at median quartile levels with attractive 
short-term and longer-term performance incentives. Share 
ownership is encouraged and all the Executive Directors are 
directly interested in the share capital of the Company or hold 
share options over the share capital. 
In setting remuneration levels, the Committee takes into 
consideration remuneration within the Group and the 
remuneration practices in other companies of a similar size in 
the markets and locations in which Avacta operates. Avacta is 
a dynamic, growing company operating in a specialised field 
and has grown significantly in size, scope and value over the 
last few years. Positions are benchmarked from time-to-time 
against comparable roles in biotech and AIM companies, with 
the last exercise carried out in January 2023 with the support 
of an external adviser, Mercer. Mercer does not provide 
any other services to the Group and is a signatory to the UK 
Remuneration Consultants Group Code of Conduct.
Executive Directors – Short-term incentives
Basic salary
Basic salary is determined by several factors including market 
rates, together with the individual Director’s experience, 
responsibilities and performance. Individual salaries of 
Directors were reviewed by the Remuneration Committee 
in January 2024. It was agreed to increase the Executive 
Director’s salaries by a 5% cost of living increase consistent 
with Group employees. Therefore, with effect from 1 January 
2024, the salary of the Chief Executive Officer would be 
increased from £343,000 to £360,000 per annum and 
the salary of the Chief Financial Officer be increased from 
£237,000 to £249,000 per annum. No further action would be 
taken at this stage to address the gap between the Executive 
Director’s salaries and the median salary data provided by 
Mercer as part of the review carried out in January 2023.
On 1 February 2024, Christina Coughlin was appointed to 
the Executive Director position of Head of Research and 
Development, having carried out a consulting role with the 
Group’s Therapeutics Division from August 2023 in addition 
to her Non-executive Director role. Christina’s Non-executive 
Director role ceased on 31 January 2024 upon commencing 
the full-time Executive Director role, with her basic salary being 
set at £375,000 per annum, reflecting the level of experience 
that Christina brings to the role and comparable salaries 
across US and European biotech companies. In addition to the 
basic salary, a one-off fee of $100,000 was paid to Christina on 
commencement of the role.
Performance-related bonus
The Company operates an annual performance-related bonus 
scheme for Executive Directors. Payments under the bonus 
scheme are at the discretion of the Board (as recommended 
by the Remuneration Committee) and are based around 
significant value creation milestones, covering financial, 
commercial, technical and operational parameters, which are 
set at the start of the financial year. The maximum bonus that 
can be earned by an Executive Director for the 2023 financial 
year was 100% of basic salary. The Committee determines on 
an annual basis the composition of the award, which can be 
split between cash, deferred share awards and share options. 
For the year ending 31 December 2022, the Chief Executive 
Officer was paid a bonus equivalent to 48% of his current 
basic salary and the Chief Financial Officer was paid a bonus 
equivalent to 36% of his current basic salary. The bonuses 
were paid in March 2023.
Remuneration Committee Report
62

Avacta Report and Accounts          2023
For the year ending 31 December 2023, the Remuneration 
Committee reviewed the performance of the Executive 
Directors against the agreed targets for the year and 
concluded that both the Chief Executive Officer and the Chief 
Financial Officer should be paid bonus equivalent to 65% of 
their basic salaries. The bonuses were paid in March 2024, a 
constructive obligation was recognised at year-end and the 
corresponding expense was included in the result for the year 
ending 31 December 2023.
Benefits in kind
The Company provides private medical and critical illness 
insurance for the Executive Directors.  
Pensions
The Company makes payments into defined contribution 
Personal Pension Plans on behalf of the Executive Directors. 
These payments are at a rate up to 6% of basic salary 
consistent with terms offered to other staff across the 
Group. Executive Directors can elect to take these pension 
contributions as additional salary payments if they so choose.
Executive Directors – Long-term incentives
Share interests
The Committee considers that the long-term motivation of 
the Executive Directors is secured by their interests in the 
share capital of the Company, operating an EMI-approved 
share option scheme, an unapproved Executive Share Option 
Scheme, a Joint Share Ownership Plan (‘JSOP’) and a Long-Term 
Incentive Plan (‘LTIP’).
The individual interests and joint interests (where applicable) 
of the Directors in the share capital of the Company are set 
out on page 65 and their interests in options held over shares 
in the Company are set out on page 51. 
Executive Directors are expected to build a direct stake in the 
Company’s shares over time, either through the purchase of 
shares in the market from time to time and/or through the 
future exercise of share options.
The Committee has an established framework of LTIP awards 
for Executive Directors and certain senior executives with most 
recent awards being granted in September 2023. No awards 
were made during 2022. 
The September 2023 LTIP award was granted with vesting 
conditions based on the share price performance of the Group 
relative to the FTSE AIM All Share Index over a three-year period 
to 31 December 2025, subject to the Board having discretion to 
review the exercise conditions in exceptional circumstances. 
Christina Coughlin, following her appointment as an Executive 
Director, will be eligible to participate in the LTIP when the next 
awards are granted.
The Company can grant share options under its share option 
schemes subject to a cap, agreed with shareholders, to be up to 
15% of total issued share capital in any ten-year period.
Executive Directors’ service agreements
The Board’s policy on setting notice periods for Directors is 
that these should not exceed one year. All Executive Directors 
have service agreements terminable on six months’ notice.
The details of the service contracts of the Executive Directors 
at 31 December 2023 are shown below.

Non-executive Directors
The Board determines the fees paid to Non-executive Directors, 
the aggregate limit for which is laid down in the Articles of 
Association. The fees, which are reviewed annually, are set 
in line with prevailing market conditions and at a level which 
will attract individuals with the necessary experience and 
ability to make a significant contribution to the Group’s affairs. 
Non-executive Directors are not involved in any discussion or 
decision about their own remuneration. The same applies to the 
Chairman of the Board, whose remuneration is determined by 
the Board on the recommendation of the Committee.
The Non-executive Directors do not participate in any of the 
Company’s pension schemes or bonus arrangements.

The Non-executive Directors are encouraged to maintain a 
shareholding within the Company and their current holdings 
are set out on page 51. None of the Non-executive Directors 
(except for Eliot Forster) hold any interest in share options 
or the joint share ownership plan of the Company. Eliot 
Forster, shortly after his appointment to the Board in 2018, 
received an award of share options, which were equivalent 
to one year’s fee for his services as Chairman. The share 
options vested equally over a three-year period and did 
not carry any performance obligations (further details are 
provided within the table on page 65). The Committee and 
Company’s advisers do not consider the share options, given 
their relatively low value in relation to Dr Forster’s fee for 
his services and his income from other roles outside of the 
Avacta Group, to impact his independence.

(2022: £3,248,000). The aggregate gain made by Directors on the exercise of share options was £nil (2022: £nil).
 
External appointments
The Committee recognises that its Directors may be invited to become Executive or Non-executive Directors of other companies or 
to become involved in charitable or public service organisations. As the Committee believes that this can broaden the knowledge and 
experience of the Company’s Directors to the benefit of the Group, it is the Company’s policy to approve such appointments provided 
there is no conflict of interest and the commitment required is not excessive. The Director concerned can retain the fees relating to 
any such appointment.
Directors’ remuneration
The remuneration of each of the Directors of the Company for the year ended 31 December 2023 is set out below. These values are 
included within the audited accounts.

Avacta Report and Accounts          2023
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. 
As required by the AIM Rules of the London Stock Exchange, 
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 in accordance with 
UK accounting standards and applicable law (UK Generally 
Accepted Accounting Practice), including FRS 102 The Financial 
Reporting Standard applicable in the UK and Republic of Ireland.  
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 their 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, reliable, and prudent; 
•	 for the Group financial statements, state whether they have 
been prepared in accordance with UK adopted international 
accounting standards;
•	 for the parent company financial statements, state whether 
applicable UK accounting standards have been followed, 
subject to any material departures disclosed and explained 
in the financial statements;
•	 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 and a Directors’ 
Report 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.

Financial Statements
1	
Accounting policies
Avacta Group plc (the ‘Company’) is a company incorporated and 
domiciled in the UK. These consolidated financial statements 
for the year ended 31 December 2023 comprise the Company 
and its subsidiaries (together referred to as the ‘Group’).  
Basis of preparation
The Group’s consolidated financial statements have been 
prepared in accordance with UK adopted international 
accounting standards. The Company has elected to prepare 
its parent company financial statements in accordance with 
applicable UK accounting standards, including Financial 
Reporting Standard 102 – The Financial Reporting Standard 
applicable in the United Kingdom and Republic of Ireland ('FRS 
102'), and with the Companies Act 2006. These parent 
company financial statements and notes appear after the 
notes to the consolidated financial statements. 
The financial statements have been prepared on the historical 
cost basis.
Functional and presentation currency
These consolidated financial statements are presented in 
pound sterling, which is the Company’s functional currency. All 
amounts have been rounded to the nearest thousand, unless 
otherwise indicated.
Going concern
These financial statements have been prepared on a going 
concern basis, notwithstanding a loss of £24.95 million and 
operating cash outflows from operations of £21.8 million for 
the year ended 31 December 2023. The Directors consider this 
to be appropriate for the following reasons.
The Directors have prepared detailed cash flow forecasts that 
extend to at least twelve months from the date of approval of 
the financial statements. The forecasts take into account the 
Directors’ views of current and future economic conditions 
that are expected to prevail over the period. These forecasts 
include assumptions regarding the status of therapeutic 
development collaborations, the AVA6000 clinical trials, and 
product development projects, together with the Launch and 
Coris sales pipelines, future revenues and costs, together with 
various scenarios which reflect growth plans, opportunities, 
risks and mitigating actions. The forecasts also include 
assumptions regarding the timing and quantum of investment 
in the therapeutic development programmes. 
Whilst there are inherent uncertainties regarding the cash 
flows associated with the development of both the therapeutic 
platforms, the Directors are satisfied that there is sufficient 
discretion and control as to the timing and quantum of cash 
outflows to ensure that the Company and Group are able to meet 
their liabilities as they fall due for at least twelve months from 
the date of approval of the financial statements. The key factors 
considered in reaching this conclusion are summarised opposite:
•	 As at 31 December 2023, the Group’s cash and cash 
equivalents were £16.6 million (2022: £41.8 million).
•	 The Group completed an equity fundraise in March 2024, 
which raised gross proceeds of £31.1 million (£29.4 million 
net proceeds).
•	 While the Group does have external borrowings in the form 
of a convertible bond with principal amount remaining of 
£40.8 million, this liability can be settled by the issue of new 
equity, rather than cash, at the discretion of the Group. 
•	 The Directors have considered the position of the individual 
trading companies in the Group to ensure that these 
companies are also in a position to continue to meet their 
obligations as they fall due.  
The Directors continue to explore additional sources of income 
and finance available to the Group to continue the development 
of the therapeutic platforms beyond 2024. The sources of 
income could come through the licensing of assets/targets 
from the proprietary Affimer® and pre|CISION™ platforms or 
through additional therapeutic collaborations, similar to the LG 
Chem and Daewoong collaborations, which may include up-front 
technology access fees and significant early-stage development 
income, or through additional equity fundraises.
Based on these indications, the Directors are confident that 
the Company will have sufficient funds to continue to meet its 
liabilities as they fall due for at least twelve months from the 
date of approval of the financial statements and therefore have 
prepared the financial statements on a going concern basis.
Use of judgements and estimates
In preparing these consolidated financial statements, 
management has made judgements and estimates 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 ongoing basis. Revisions to estimates are recognised 
prospectively.
Information about judgements and estimates made by 
management that have the most significant effects on the 
amounts recognised in the financial statements is given below.
The Directors consider that the key judgements made in 
preparation of the financial statements are:
Going concern - The judgement of whether or not the 
accounts should be prepared on a going concern basis has 
been disclosed above.
Revenue recognition – Judgements arise from the application 
of IFRS 15 to the Group’s revenue streams, as disclosed in 
Note 1C, as to the timing and nature of revenue recognised in 
relation to the achievement of milestones.
Notes to the Consolidated  
Financial Statements
86

Avacta Report and Accounts          2023
The Directors consider that the assumptions and estimation 
uncertainties at 31 December 2023 that have a significant risk of 
resulting in a material adjustment to the carrying amounts and 
liabilities in the next financial year are: 
Impairment – Impairment tests have been performed on 
the carrying amounts of the Group’s cash-generating units. 
Further information on the key assumptions underlying these 
tests is disclosed in Note 10.
Acquisitions – Estimation uncertainty is inherent in the 
methods used to determine the fair value of consideration 
and of the assets acquired and liabilities assumed, as set out 
in Note 26. These include the valuation of acquired intangible 
assets and the estimate of deferred consideration payable.
Convertible bond – Determining the fair value of the 
embedded derivative within the convertible bond, both at 
conversion dates and at the reporting date. See Note 22.
The estimates and judgements relevant to the Company 
financial statements have been disclosed in Note 30.
Changes in accounting policies
a.	 New standards and interpretations adopted from 1 
January 2023
The following amendments to IFRS accounting standard are 
mandatorily effective for reporting periods beginning on or 
after 1 January 2023. They have impacted the Group financial 
statements as follows:
•	 Disclosure of Accounting Policies (Amendments to IAS 1 
Presentation of Financial Statements and IFRS Practice 
Statement 2 Making Materiality Judgements) 
 
In February 2021, the IASB issued amendments to IAS 1 
and IFRS Practice Statement 2. The amendments aim to 
make accounting policy disclosures more informative by 
replacing the requirement to disclose ‘significant accounting 
policies’ with ‘material accounting policy information’. 
The amendments also provide guidance under what 
circumstance, the accounting policy information is likely to 
be considered material and therefore requiring disclosure.  
 
These amendments have no effect on the measurement 
or presentation of any items in the Consolidated financial 
statements of the Group but affect the disclosure of 
accounting policies of the Group. 
•	 Definition of Accounting Estimates (Amendments to IAS 8 
Accounting policies, Changes in Accounting Estimates and Errors)  
 
The amendments to IAS 8, which added the definition of 
accounting estimates, clarify that the effects of a change in an 
input or measurement technique are changes in accounting 
estimates, unless resulting from the correction of prior period 
errors. These amendments clarify how entities make the 
distinction between changes in accounting estimate, changes 
in accounting policy and prior period errors.  
 
These amendments had no effect on the consolidated 
financial statements of the Group.
•	 Deferred Tax related to Assets and Liabilities arising from a 
Single Transaction (Amendments to IAS 12 Income Taxes)  
 
In May 2021, the IASB issued amendments to IAS 12, which 
clarify whether the initial recognition exemption applies 
to certain transactions that result in both an asset and a 
liability being recognised simultaneously (e.g. a lease in the 
scope of IFRS 16). The amendments introduce an additional 
criterion for the initial recognition exemption, whereby the 
exemption does not apply to the initial recognition of an 
asset or liability which at the time of the transaction, gives 
rise to equal taxable and deductible temporary differences.  
 
These amendments had no material effect on the 
consolidated financial statements of the Group.
b.	 New standards and interpretations not yet effective 
There are a number of standards, amendments to standards, 
and interpretations which have been issued by the IASB that 
are effective in future accounting periods that the Group has 
decided not to adopt early. 
The following amendments are relevant to the Group and are 
effective for the period beginning 1 January 2024: 
•	 Liability in a Sale and Leaseback (Amendments to IFRS 16 
Leases)
•	 Classification of Liabilities as Current or Non-Current 
(Amendments to IAS 1 Presentation of Financial Statements)
The following amendments are relevant to the Group and are 
effective for the period beginning 1 January 2025:
•	 Lack of Exchangeability (Amendments to IAS 21 The Effects 
of Changes in Foreign Exchange Rates) 
The Group does not expect any accounting standards that are 
issued but not yet effective, to have a material impact on the 
financial statements of the Group.
Significant accounting policies
The Group has consistently applied the following accounting 
policies to all periods presented in these consolidated financial 
statements, except if mentioned otherwise.
A - Basis of consolidation
The Group accounts for business combinations using the 
acquisition method when control is transferred to the Group. 
The consideration transferred in the acquisition is measured 
at fair value, as are the identifiable net assets acquired. Any 
goodwill that arises is tested annually for impairment. Any 
gain on a bargain purchase is recognised in profit or loss 
immediately. Transaction costs are expensed as incurred, 
except if related to the issue of debt or equity securities.
The consideration transferred does not include amounts 
related to the settlement of pre-existing relationships. Such 
amounts are generally recognised in profit or loss.
87
>

Financial Statements
A - Basis of consolidation (continued)
Any contingent consideration is measured at fair value to the date 
of acquisition. If an obligation to pay contingent consideration 
that meets the definition of a financial instrument is classified as 
equity, then it is not remeasured and settlement is accounted 
for within equity. Otherwise, other contingent consideration is 
remeasured at fair value at each reporting date and subsequent 
changes in the fair value of the contingent consideration are 
recognised in profit or loss.
Subsidiaries are entities controlled by the Group. The Group 
controls an entity when it is exposed to, or has rights to, variable 
returns from its involvement with the entity and has the ability 
to affect those returns through its power over the entity. 
The financial statements of subsidiaries are included in the 
consolidated financial statements from the date on which control 
commences until the date on which control ceases. Control 
exists when the Company has the power, directly or indirectly, to 
govern the financial and operating policies of an entity so as to 
obtain benefits from its activities. In assessing control, potential 
voting rights that presently are exercisable or convertible are 
considered. The financial statements of subsidiaries are included 
in the consolidated financial statements from the date that 
control commences until the date that control ceases.
The Group’s interests in equity-accounted investees comprises 
an interest in an associate (AffyXell Therapeutics, see Note 23). 
Associates are those entities in which the Group has significant 
influence, but not control or joint control, over the financial and 
operating policies. Interests in associates are accounted for using 
the equity method. They are initially recognised at cost, which 
includes transaction costs. Subsequent to initial recognition, the 
consolidated financial statements include the Group’s share 
of the profit or loss and other comprehensive income (‘OCI’) of 
equity-accounted investees, reduced by distributions received by 
the investee, until the date on which significant influence ceases.
Intra-group balances and transactions, and any unrealised 
income and expenses arising from intra-group transactions, 
are eliminated. Increases in the investment in AffyXell arise 
through the settlement of amounts receivable, for achievement 
of milestones under the collaboration agreement, in additional 
equity in the entity. See Note 1C for further details.
B – Foreign currency
Transactions in foreign currencies are translated into the 
respective functional currencies of Group companies at the 
exchange rates at the dates of the transactions.
Monetary assets and liabilities denominated in foreign currencies 
are translated into the functional currency at the exchange rate 
at the reporting date. Non-monetary items that are measured 
based on historical cost in a foreign currency are translated 
at the exchange rate at the date of the transaction. Foreign 
currency differences are generally recognised in profit or loss and 
presented within administrative expenses, or in OCI where they 
relate to the net investment in a foreign operation.
The assets and liabilities of foreign operations are translated into 
pound sterling at the exchange rates at the reporting date. The 
income and expenses of foreign operations are translated into 
pound sterling at the average exchange rates relevant to the 
reporting period.
C – Revenue from contracts with customers
Revenue is measured based on the consideration specified in a 
contract with a customer. The Group recognises revenue when 
it transfers control over a good or service to a customer. The 
following table provides information about the nature and timing 
of the satisfaction of performance obligations in contracts with 
customers, including significant payment terms, and the related 
revenue recognition policies.

Financial Statements (continued)

Therapeutics
Payments received during the period in relation to assignment of patent rights to AffyXell are 
considered to be a right-to-use the relevant intellectual property (‘IP’), and therefore revenue 
is recognised at the point in time the performance obligation is satisfied. The payment is 
assessed as for a right to use the relevant IP primarily as a result of the Group not undertaking 
activities that significantly affect the IP to which AffyXell has rights during the respective contracts.
Transaction price is determined to be the fair value of shares issued by AffyXell to the Group 
as consideration. Revenue is recognised at the point in time that the performance obligation 
is satisfied, being the point in time at which the patent rights are assigned to the customer. An 
adjustment is made to eliminate profit on the downstream sale, which is reversed over time as 
the asset is realised by the investee.
Diagnostic 
reagent test 
sales
Diagnostics
The performance obligation for these sales is the transfer of control of the goods to the 
customer. The timing of this is determined by the terms and conditions of the reagent 
transportation but are usually either at the point of despatch or on receipt by the customer. 
Revenue is recognised at the point in time this performance obligation is satisfied.
Transaction prices for these performance obligations do not contain any variable elements.

Avacta Report and Accounts          2023
D - Employee benefits
Short-term employee benefits are expensed as the related 
service is provided. A liability is recognised for the amount 
expected to be paid if the Group has a present legal or 
constructive obligation to pay this amount as a result of past 
service provided by the employee and the obligation can be 
estimated reliably.
The grant-date fair value of equity-settled share-based 
payment arrangements granted to employees is generally 
recognised as an expense, with a corresponding increase in 
equity, over the vesting period of the awards. The amount 
recognised as an expense is adjusted to reflect the number 
of awards for which the related service and non-market 
performance conditions are expected be met, such that 
the amount ultimately recognised is based on the number 
of awards that meet the related service and non-market 
performance conditions at the vesting date. For share-based 
payment awards with market or non-vesting conditions, the 
grant-date fair value of the share-based payment is measured 
to reflect such conditions and there is no true-up for 
differences between expected and actual outcomes. Fair value 
measurement is discussed in more detail in Note 1M below. 
Obligations for contributions to defined contribution plans are 
expensed as the related service is provided. 
Termination benefits are expensed at the earlier of when the 
Group can no longer withdraw the offer of those benefits and 
when the Group recognises costs for a restructuring. 
Where the terms and conditions on which equity instruments 
were granted are modified, such as through a settlement, 
the Group accounts for the modification as an acceleration 
of vesting and immediately recognises the amount that 
would otherwise have been recognised for services over the 
remainder of the vesting period.
E – Finance income and finance costs
The Group’s finance income and finance costs include:
•	 interest income;
•	 interest expense on lease liabilities (see Note 1L); and
•	 interest expense and gains/losses on revaluation of 
derivative in respect of convertible bond (see Note 1J).
Interest income on cash deposits is recognised in the profit or 
loss as it is earned.
F – Taxation
The income tax credit comprises current and deferred tax. It 
is recognised in the statement of profit or loss except to the 
extent that it relates to items recognised directly in equity, in 
which case it is recognised in equity. 
The current tax credit relates to the expected Small and 
Medium Sized Enterprise R&D relief receivable for the year, 
and any adjustment to the amount receivable in respect of 
previous years, net of current tax payable. The amount of 
current tax receivable is the best estimate of the tax amount 
expected to be received that reflects the related uncertainty. 
It is measured using the applicable rates enacted or 
substantively enacted at the reporting date. 
Deferred tax is recognised in respect of temporary differences 
between the carrying amounts of assets and liabilities for 
financial reporting purposes and the amounts used for 
taxation purposes, except for when they arise on the initial 
recognition of goodwill. Deferred tax assets are recognised 
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. Future taxable profits are determined based 
on the reversal of relevant taxable temporary differences. If 
the amount of taxable temporary differences is insufficient 
to recognise a deferred tax asset in full, then future taxable 
profits, adjusted for reversals of existing temporary differences, 
are considered, based on the business plans for individual 
subsidiaries in the Group and the expected manner of offsetting 
existing tax losses against these future taxable profits. 
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.
The Group has determined that the global minimum top-
up tax is an income tax in the scope of IAS 12. The Group 
has applied a temporary mandatory relief from deferred tax 
accounting for the impacts of the top-up tax and accounts for 
it as a current tax where it is incurred. The Group’s revenues 
reported revenues for the year ended 31 December 2023 
mean that it is not subject to the global minimum top-up tax.
G – Inventories
Inventories are measured at the lower of cost and net 
realisable value. Cost is determined using the weighted 
average cost basis. 
At each reporting date, the Group assesses whether 
inventories are impaired or if an impairment loss recognised 
in prior periods has reversed. Any excess of the carrying 
amount of inventory over its estimated selling price less costs 
to complete and sell is recognised as an impairment loss in the 
income statement.

Financial Statements
H – Property, plant and equipment
Property, plant and equipment are held at cost less 
accumulated depreciation and any accumulated 
impairment losses.
Any gain or loss on disposal of an item of property, plant 
and equipment is recognised in profit or loss.
Depreciation is calculated to write off the cost of items of 
property, plant and equipment less their estimated residual 
values using the straight-line method over their estimated 
useful lives, and is recognised in profit or loss.
The estimated useful lives of property, plant and equipment 
for current and comparative periods are as follows:
Laboratory equipment	
3 to 10 years
Office fixtures and fittings	
3 to 10 years
Leasehold improvements	
5 to 15 years
Motor vehicles	
	
3 to 5 years
Depreciation methods, useful lives and residual values are 
reviewed at each reporting date and adjusted if appropriate. 
Assets in the course of construction are carried at cost, less 
any identified impairment. Cost includes professional fees 
and other directly attributable costs that are necessary to 
bring the assets to their operating condition. Depreciation 
commences when the assets are ready for their intended use.
I – Intangible assets and goodwill
i)  Research and development
Research and development – Expenditure on research activ-
ities is recognised in profit or loss as incurred. Development 
expenditure is capitalised on a research and development 
project only if the expenditure can be measured reliably, the 
product or process is technically and commercially feasible, 
future economic benefits are probable and the Group intends 
to and has sufficient resources to complete development and 
to use or sell the asset. Otherwise, it is recognised in profit or 
loss as incurred. 
Research expenditure relating to Therapeutics work is expensed 
in the period it is incurred, consistent with pharmaceutical 
industry practice. Given the stage of development of the 
technology, with the most advanced candidate being in Phase 
1 of a clinical trial, there is a significant risk that a commercial 
product may not materialise, and so there is not sufficient 
certainty that the relevant expenditure satisfies the commercial 
or technical feasibility criteria. These criteria would be expected 
to be satisfied after regulatory approval, typically following 
completion of Phase 3 trials.
For Diagnostics, an assessment is made of the research and 
development expenditure on a project-by-project basis to 
identify which expenditure satisfies the above capitalisation 
criteria. The key judgement involved is considered to be the 
assessment of the stage of development of the project, and 
whether it can be demonstrated that a project has commercial 
or technical feasibility. A broader judgement is also made 
around the availability of sufficient financial resources to 
complete the development projects, which is fundamentally 
linked to the going concern assessment discussed earlier 
in Note 1. For Diagnostics projects, the technical feasibility 
criteria would generally be expected to be satisfied once 
a working prototype was in place and appropriate clinical 
validation had been performed.
Subsequent to initial recognition, development expenditure 
is measured at cost less accumulated amortisation and any 
accumulated impairment losses. A periodic review of existing 
capitalised development costs is performed to identify costs 
relating to projects which are no longer considered to satisfy 
the capitalisation criteria. For such costs, an impairment 
charge is recognised in profit or loss.
ii)  Goodwill 
Goodwill arising on the acquisition of subsidiaries is measured 
at cost less accumulated impairment losses.
At each reporting date, the Group reviews the carrying 
amounts of its non-financial assets to determine whether 
there is any indication of impairment. If any such indication 
exists, then the asset’s recoverable amount is estimated. 
Goodwill is tested annually for impairment.
For impairment testing, assets are grouped together into the 
smallest group of assets that generates cash inflows from 
continuing use that are largely independent of the cash inflows 
of other assets or group of assets. These groups of assets are 
referred to as cash-generating units (‘CGUs’). Goodwill arising 
from a business combination is allocated to CGUs that are 
expected to benefit from the synergies of the combination, 
with each unit or group of units to which goodwill is allocated 
representing the lowest level within the Group at which the 
goodwill is monitored for internal management purposes, and 
not being larger than an operating segment.
This results in a two-step approach to impairment testing. 
An impairment test is first performed for individual cash-
generating units with indicators of impairment or those 
containing goodwill. An impairment test is then performed for 
the group of CGUs to which goodwill can be allocated.
The recoverable amount of an asset, CGU, or group of CGUs 
is the greater of its value in use and its fair value less costs 
to sell. Value in use is based on the estimated future cash 
flows, discounted to their present value using a discount rate 
that reflects current market assessments of the time value 
of money and the risks specific to the asset or CGU. The 
recoverable amount of a group of CGUs is the sum of the 
individual CGU value in uses.
Notes to the Consolidated  
Financial Statements (continued)
90

Avacta Report and Accounts          2023
An impairment loss is recognised if the carrying amount of an 
asset, CGU, or group of CGUs including goodwill exceeds its 
recoverable amount.
Impairment losses are recognised in profit or loss. They are 
allocated first to reduce the carrying amount of any goodwill 
allocated to the CGU, or group of CGUs, and then to reduce 
the carrying amounts of the other assets in the CGU on a pro 
rata basis.
An impairment loss in respect of goodwill is not reversed. For 
other assets, an impairment loss is reversed only to the extent 
that the asset’s carrying amount does not exceed the carrying 
amount that would have been determined, net of depreciation 
or amortisation, if no impairment loss had been recognised.
iii)  Other intangible assets
Other intangible assets, including software and patents that 
are acquired by the Group and have finite useful lives, are 
measured at cost less accumulated amortisation and any 
accumulated impairment losses.
Amortisation is calculated to write off the cost of intangible 
assets less their estimated residual values using the straight-
line method over their estimated useful lives, and is recognised 
in profit or loss. Goodwill is not amortised.
The estimated useful lives for current and comparative periods 
are as follows:
•	 Development expenditure relating to Diagnostics products 
is amortised on a straight-line basis over the expected 
useful life of the technology, being 5 to 15 years
•	 Software: amortised over the useful life of the software, 
being 3 to 5 years
•	 Patents: amortised over the same period as the length of 
the life of the patent, being up to 20 years
•	 Brand: amortised over the useful life of the asset, being 
10 years
•	 Customer relationships: amortised over the useful life of the 
asset, being 10 to 15 years
J – Financial instruments
The Group classifies its financial assets in the following 
measurement categories:
•	 Those to be measured subsequently at fair value (either 
through other comprehensive income (‘OCI’) or through 
profit or loss)
•	 Those to be measured at amortised cost 
The classification depends on the entity’s business model for 
managing the financial assets and the contractual terms of the 
cash flows. 
At initial recognition, the Group measures a financial asset 
at its fair value plus, in the case of a financial asset not at fair 
value through profit or loss (‘FVPL’), transaction costs that 
are directly attributable to the acquisition of the financial 
asset. Transaction costs of financial assets carried at FVPL are 
expensed in profit or loss. 
Subsequent measurement of debt instruments depends on the 
Group’s business model for managing the asset and the cash 
flow characteristics of the asset. The measurement categories 
into which the Group classifies its debt instruments are:
•	 Amortised cost: Assets that are held for collection of 
contractual cash flows, where those cash flows represent 
solely payments of principal and interest, are measured at 
amortised cost. Interest income from these financial assets 
is included in finance income using the effective interest 
rate method. Any gain or loss arising on derecognition is 
recognised directly in profit or loss and presented in other 
gains/(losses) together with foreign exchange gains and 
losses. Impairment losses are presented as a separate line 
item in the statement of profit or loss. 
•	 FVPL: Assets that do not meet the criteria for amortised cost 
are measured at FVPL. A gain or loss on a debt investment 
that is subsequently measured at FVPL is recognised in 
profit or loss and presented net within other gains/ (losses) 
in the period in which it arises.
Cash and cash equivalents comprise cash balances and short-
term deposits. Cash and bank overdrafts are offset and the net 
amount reported in the balance sheet when there is a legally 
enforceable right to offset the recognised amounts, there is an 
intention to settle on a net basis and interest is charged on a 
net basis.
Financial liabilities are classified as measured at amortised 
cost or FVPL. A financial liability is classified as at FVPL if it is 
classified as held-for-trading, it is a derivative or it is designated 
as such on initial recognition. Financial liabilities at FVPL are 
measured at fair value and net gains and losses, including any 
interest expense, are recognised in profit or loss. Other financial 
liabilities are subsequently measured at amortised cost using 
the effective interest method. Interest expense and foreign 
exchange gains and losses are recognised in profit or loss.
The Group’s convertible bond is accounted for as a hybrid 
instrument, with a non-derivative host contract and an 
embedded derivative. The embedded derivative relates to the 
ability for the bond to be settled in shares, therefore causing 
some of the cashflows of the instrument to vary according to 
the Group’s share price. At inception, the host debt contract 
was measured at the issue price adjusted for a proportion of 
transaction costs and the inception fair value of the embedded 
derivative. The host debt contract is subsequently measured 
at amortised cost The embedded derivative is measured at 
fair value using a Monte-Carlo option pricing model, which 
91
>

Financial Statements
estimates fair value based on the probability-weighted present 
value of expected future investment returns, considering each 
of the possible outcomes available to the bondholders. This 
is a Level 3 fair value measurement, as described in Note 1M. 
Gains or losses on remeasurement of the fair value of the 
embedded derivative are recognised through the profit or loss.
The convertible bond contains scheduled quarterly 
amortisation events, and the ability for the bondholder to 
elect to settle a portion of the bonds early, with both events 
settled in shares at the discretion of the Group. Where shares 
are issued in settlement of the convertible bond, the total 
reduction in liability (of the host debt and derivative elements) 
is recognised within share premium. The reduction in the 
host debt liability is the aggregate principal and interest 
amounts settled. The reduction in the derivative liability is the 
value to the bondholder of the shares issued in excess of the 
aggregate principal and interest amounts. Early conversion 
events revise the future estimated cashflows under the bond, 
as such the host debt liability must be remeasured using 
the original effective interest rate, with recognition of any 
subsequent gain or loss.
Further details on the convertible bond are discussed in Note 22. 
K – Operating segments
An operating segment is a component of the Group that 
engages in business activities from which it may earn revenues 
and incur expenses, including revenues and expenses 
that relate to transactions with any of the Group’s other 
components. An operating segment’s operating results are 
reviewed regularly by the Group’s chief operating decision-
maker (‘CODM’) to make decisions about resources to be 
allocated to the segment and assess its performance, and for 
which discrete financial information is available.
In accordance with IFRS 8 Operating Segments, the Group 
determines and presents operating segments based on 
the information that internally is provided to the Board of 
Directors. Accordingly, the Board of Directors, which reviews 
internal monthly management reports, budget and forecast 
information, is deemed to be the Group’s CODM. 
The Group has two operating segments, these being the 
level at which the CODM makes decisions on strategy and 
capital allocation.
L - Leases
At inception of a contract, the Group assesses whether a 
contract is, or contains, a lease. A contract is, or contains, 
a lease if the contract conveys the right to control the use 
of an identified asset for a period of time in exchange for 
consideration. To assess whether a contract conveys the right 
to control the use of an identified asset, the Group uses the 
definition of a lease in IFRS 16. 
For the leases of property the Group has elected not to 
separate non-lease components and account for the lease and 
non-lease components as a single lease component. 
The Group recognises a right-of-use asset and a lease liability at 
the lease commencement date. The right-of-use asset is initially 
measured at cost, which comprises the initial amount of the 
lease liability adjusted for any lease payments made at or before 
the commencement date, plus any initial direct costs.
The right-of-use asset is subsequently depreciated using the 
straight-line method from the commencement date to the end 
of the lease term, unless the lease transfers ownership of the 
underlying asset to the Group by the end of the lease term. In 
that case the right-of-use asset will be depreciated over the 
useful life of the underlying asset, which is determined on the 
same basis as those of property and equipment. In addition, 
the right-of-use asset is periodically reduced by impairment 
losses, if any, and adjusted for certain remeasurements of the 
lease liability. 
The lease liability is initially measured at the present value of 
the lease payments that are not paid at the commencement 
date, discounted using the Group’s incremental borrowing 
rate. The Group’s incremental borrowing rate is the rate of 
interest that the Group would have to pay to borrow over a 
similar term, and with a similar security, the funds necessary to 
obtain an asset of a similar value to the right-of-use asset in a 
similar economic environment.
Lease payments included in the measurement of the lease 
liability comprise the following: 
•	 Fixed payments, including in-substance fixed payments
•	 Lease payments in an optional renewal period if the Group 
is reasonably certain to exercise an extension option
The lease liability is measured at amortised cost using the 
effective interest method. It is remeasured if the Group 
changes its assessment of whether it will exercise an 
extension or termination option.
When the lease liability is remeasured in this way, a 
corresponding adjustment is made to the carrying amount 
of the right-of-use asset, or is recorded in profit or loss if the 
carrying amount of the right-of-use asset has been reduced 
to zero. 
The Group has elected not to recognise right-of-use assets 
and lease liabilities for leases of low-value assets and short-
term leases, including IT equipment. The Group recognises 
the lease payments associated with these leases as an 
expense on a straight-line basis over the lease term.

Financial Statements (continued)

Avacta Report and Accounts          2023
M – Fair value measurement
A number of the Group’s accounting policies and disclosures 
require the measurement of fair values, for both financial and 
non-financial assets and liabilities.
The fair value measurement of the Group’s financial and 
non-financial assets and liabilities utilises market observable 
inputs and data as far as possible. Inputs used in determining 
fair value measurements are categorised into different levels 
based on how observable the inputs used in the valuation 
technique utilised are (the ‘fair value hierarchy’): 
Level 1: Quoted prices in active markets for identical items 
(unadjusted) 
Level 2: Observable direct or indirect inputs other than 
Level 1 inputs 
Level 3: Unobservable inputs (i.e. not derived from market 
data). 
The classification of an item into the above levels is based on 
the lowest level of the inputs used that has a significant effect 
on the fair value measurement of the item. 
The Group measures the following financial instruments at fair 
value, all considered to be Level 3 measurements:
- Contingent consideration receivable (Note 27)
- Derivative element of the convertible bond (Note 22)
A description of the valuation technique and a reconciliation 
of the opening and closing values is provided in the respective 
notes listed above. 
N – Alternative performance measures
This Group presents an alternative performance measure 
(‘APM’), adjusted EBITDA, in the Consolidated Statement of 
Profit or Loss. Adjusted EBITDA is presented to enhance 
an investor’s evaluation of ongoing operating results, by 
facilitating both a meaningful comparison of results between 
periods and identification of the underlying cash used by 
operations within the business. Items of expenditure excluded 
from the adjusted EBITDA measure are those where the 
relative magnitudes year-on-year are not directly reflective 
of year-on-year performance, or are not closely linked to 
the underlying cashflows from operations. There is a clear 
reconciliation between adjusted EBITDA and operating loss in 
the Consolidated Statement of Profit or Loss. It is noted that 
the above APM is not a substitute for IFRS measures, and may 
not be directly comparable to similarly titled measures used by 
other companies.

Segment Reporting
Operating segments
In the view of the Board of Directors, the Group has two (2022: 
two) distinct reportable segments, which are Diagnostics and 
Therapeutics (2022: Diagnostics and Therapeutics), and segment 
reporting has been presented on this basis. The Directors 
recognise that the operations of the Group are dynamic and 
therefore this position will be monitored as the Group develops.
The principal activities of each reportable segment in the current 
and prior year are as follows:
Diagnostics: development and sale of innovative, next generation 
diagnostic solutions and disruptive immunodiagnostic products
Therapeutics: development of novel cancer therapies harnessing 
proprietary technology
Segment revenue represents revenue from external customers 
arising from sale of goods and services, plus inter-segment 
revenues. Inter-segment transactions are priced on an arm’s 
length basis. Segment results, assets and liabilities include items 
directly attributable to a segment as well as those that can be 
allocated on a reasonable basis.
The Group’s revenue to destinations outside the UK amounted to 
45% (2022: 74%) of total revenue. The revenue analysis below is 
based on the country of registration of the customer:

The Group operates the following schemes:
• An HM Revenue and Customs (‘HMRC’) approved enterprise management incentive plan (‘EMI scheme’)
• An unapproved share option plan (‘Unapproved scheme’)
• An HMRC approved employee share incentive plan (‘SIP’)
• A Joint Share Ownership Plan (‘JSOP’)
The Group recognised a total share-based payment charge to the income statement of £2,906,000 (2022: £7,490,000).
EMI, unapproved and collaboration options
Details of the EMI, unapproved and collaboration options currently granted and unexercised, which are all equity settled, 
are given opposite.
The contract assets primarily relate to the Group’s rights to consideration for work completed but not invoiced at the reporting date. 
The contract assets are transferred to receivables when the rights become unconditional; this usually occurs when the Group issues 
an invoice to the customer. The contract liabilities primarily relate to advance consideration received from customers.
Of the £273,000 (2022: £51,000) in contract liabilities at the beginning of the period, £262,000 (2022: £31,000) has been recognised 
as revenue for the year ended 31 December 2023.

Financial Statements
These options are share-based payments and are measured at fair value at the date of grant. The fair value determined at the 
grant date of equity-settled share-based payments is expensed on a straight-line basis over the vesting period, based on the 
Group’s estimate of shares that will eventually vest. If options remain unexercised after a period of ten years from the date of 
grant, the options expire. Furthermore, options are forfeited if the employee leaves the Group before the options vest.  
Fair value is measured by use of the Black-Scholes option pricing model. Expected volatility was determined by calculating the 
historical volatility of the Group’s share price over a period commensurate with the expected life of the option. The expected 
life used in the model has been adjusted, based on management’s best estimate at the date of grant, for the effects of non-
transferability, exercise restrictions and behavioural considerations.
The fair value of the options granted in relation to collaboration agreements has also been measured using the above method, as 
the fair value of the services received cannot be estimated reliably through other methods.
The inputs into the Black-Scholes models for the options granted during the year were as follows. No options were granted in the 
previous year:

Avacta Report and Accounts          2023
The options outstanding at 31 December 2023 had a range of exercise prices from 10p to 118.5p (2022: 10p to 118.5p), a 
weighted average exercise price of 15.40p (2022: 17.45p), and a weighted average remaining contractual life of seven years and 18 
weeks (2022: six years and 31 weeks).
Joint Share Ownership Plan
The Joint Share Ownership Plan (‘JSOP’) covers certain employees who have a joint interest in shares with Avacta Group Trustee 
Limited as trustee of The Avacta Employees’ Share Trust. At 31 December 2023, five employees (2022: five) had joint interests in 
2,782,306 (2022: 2,782,306) ordinary shares in the Company. The Joint Share Ownership Agreements are dated 15 February 2016, 
or 21 February 2014, or 9 January 2012 between each employee individually, Avacta Group Trustee Limited and Avacta Group plc. 
Each employee has purchased 1% of the ordinary shares and the Avacta Group Trustee Limited owns 99% of the ordinary shares. 
The agreements operate when a Capital event occurs, being the sale or partial sale of the Company’s ordinary shares. If the 
proceeds per ordinary share are more than the original market price on the date the agreement was entered into then a formula 
sets out the sharing of the gain between the employee and Avacta Group Trustee Limited.
These joint interests have been treated as employee benefits and the fair value at the date of issue of the shares based on the 
Group’s estimate of the number of shares that will eventually be sold and the price at which they will be sold on a straight-line 
basis from the date that a sale becomes probable to the date at which they are anticipated to be sold.
Share Incentive Plan
The Group operates an HMRC-approved Share Incentive Plan (‘SIP’). The SIP is operated on behalf of the Group by Link Market 
Services Trust Limited as Trustee for the SIP. Certain employees based on eligibility criteria are issued free shares up to a 
maximum £3,000 as part of their annual performance review. On 28 February 2023, 55,331 ordinary shares of 10p each were 
issued in relation to the Free Share award based on the closing middle market price of 161.0p on 24 February 2023. 
In addition to the free share awards, the Group also operates a matching and partnership share arrangement whereby for 
each one share purchased by the employee via salary deduction a matching share was awarded by the Group. The maximum 
amount that can be subscribed for by employees via salary deduction is £1,800 per annum. As at 31 December 2023, 19 eligible 
employees had binding commitments to subscribe for partnership shares during the year ending 31 December 2023.
Free share awards are met through a combination of reallocating ordinary shares which have been forfeited by leavers from within 
the SIP and through the issue of new ordinary shares when required. Matching share awards to date have generally been met 
from continued on-market purchases by Link Market Services Trustees Limited as Trustee of the SIP. 
As at 31 December 2023, the Trustee held 627,299 (2022: 1,010,042) ordinary shares of 10p on behalf of the SIP.

Earnings per ordinary share 
The calculation of earnings per ordinary share is based on the profit or loss for the period and the weighted average number of 
equity voting shares in issue excluding own shares held jointly by the Avacta Employees’ Share Trust and certain employees and 
the shares held within the Avacta Share Incentive Plan (‘SIP’). 
At 31 December 2023, 25,491,642 options (2022: 20,444,462) have been excluded from the diluted weighted-average number of 
ordinary shares calculation because, due to the loss for the period, their effect would have been anti-dilutive. Further details on 
share options are set out in Note 5. 
At 31 December 2023, no potentially dilutive shares relating to the convertible bond (2022: 5,314,010) have been excluded from 
the diluted weighted-average number of ordinary shares calculation because, due to the loss for the period, their effect would 
have been anti-dilutive. Further details on the convertible bond are set out in Note 22.
In January 2024, 3,425,373 new ordinary shares of 10p each were issued in settlement of the quarterly principal of £2.55 million 
and interest repayment of £0.66 million in respect of the unsecured convertible bond.
On 4 March 2024, 27,390,485 ordinary shares of 10p each were allotted and issued at 50p further to a placing of shares, with a 
further 130,000 ordinary shares of 10p each being allotted and issued in relation to a management subscription of shares. On 
19 March 2024, a further 23,879,124 conditional placing shares and 10,896,948 REX offer shares of 10p each were allotted and 
issued at 50p. 
In April 2024, 7,529,825 new ordinary shares of 10p each were issued in settlement of the quarterly principal of £2.55 million and 
interest repayment of £0.62 million in respect of the unsecured convertible bond.

Avacta Report and Accounts          2023
Goodwill
Goodwill arising on business combinations is allocated to the Group’s cash-generating units (‘CGUs’) based on an assessment of 
which CGUs, or group of CGUs, will derive benefit from each acquisition. See Note 1I for the definition of a cash-generating unit.
The Therapeutics goodwill relates to the individual Therapeutics CGU. Goodwill arising from the acquisitions of Launch Diagnostics 
and Coris BioConcept is allocated to the group of Diagnostics CGUs, being the lowest level at which goodwill is monitored for 
internal management purposes, and the level at which benefit is expected to be derived from the acquisitions.
Goodwill is not amortised, but is tested annually for impairment at this CGU, or group of CGUs, level.

Impairment review
Goodwill is not amortised, but is tested annually for impairment at the CGU, or group of CGUs, level. Impairment tests are 
mandatory for CGUs, or groups of CGUs, containing goodwill acquired in a business combination. Impairment tests for other 
CGUs are carried out when an indication of impairment is considered to exist, such as operating losses. 
Therapeutics
The Therapeutics CGU contains goodwill and so is tested annually for impairment. The recoverable amount of this CGU was 
based on a value-in-use calculation, using discounted cash-flow projections. The key assumptions used in the estimation of the 
recoverable amount are considered to be as follows:
•	 Modelled growth over a ten-year period, this time frame reflecting management’s best estimate of the period at which revenue 
growth of the CGU would be above the long-term background growth rate. This time frame exceeds the usual five-year period 
due to the stage of the development pipeline, and the length of time expected to be taken to generate ongoing commercial 
revenues from such work.
•	 Revenue growth is forecasted to increase to circa £60 million over the modelled growth period. Growth rates are based on 
management’s risk-adjusted expectations of commercial licence revenues from the existing development pipeline, and existing 
collaborations. 
•	 Terminal growth rate after the modelled growth phase of 4.1% (2022: 3.5%), approximating the long-term average growth rate
•	 Pre-tax discount rate of 19.0% (2022: 19%), derived from a weighted-average cost-of-capital of 15% (2022: 15%)
Using the assumptions listed above, the value in use of the Therapeutics CGU exceeds its carrying amount by £48.5 million.
AVA6000, the lead development candidate, is in Phase 1 clinical trials and the risk associated with the remaining clinical trial 
pathway presents a risk that future commercial revenues may not occur in the quantum or within the time frame estimated by 
management, which may result in the carrying amount exceeding the recoverable amount of the CGU.
With an assumption that future cashflow estimates remain unchanged, the pre-tax discount rate would need to increase to 26% to 
result in an impairment.

Diagnostics
As set out in Note 1I, a two-step approach to impairment testing is followed for the Diagnostics segment, with individual CGUs 
tested for impairment where there are specific indicators, such as operating losses, and then a mandatory impairment test 
performed at the level of the group of Diagnostics CGUs due to the presence of goodwill.
Indicators of impairment were identified in one constituent CGU of the Diagnostics group, a French distribution operation. An 
impairment charge of £512,000  arose due to the carrying amount of the CGU exceeding its recoverable amount (value-in-use) 
of £2,349,000. The impairment charge is considered to have arisen from the faster than expected reduction in COVID sales. This 
impairment charge has been recognised pro rata against those non-current assets of the CGU whose value is not supported by 
their estimated fair value. Impairment charges of £28,000 against right-of-use assets, £73,000 against brand intangible assets 
and £487,000 against customer relationship intangible assets were recognised. Key assumptions used in the estimation of the 
recoverable amount include:
•	 Modelled growth over a ten-year period of 10% p.a., exceeding the usual five-year period, which reflects historical growth rates 
and management’s best estimate of the period expected to be taken for the CGU to reach a steady-state of growth, due to 
recent expansion of the CGU and the elongated time frame for revenue growth to be realised due to tender cycles.
•	 Terminal growth rate after the forecast period of 3.10%, approximating the long-term average growth rate
•	 Gross margin of 35%, based on historical gross margins achieved
•	 Overhead growth rates reflecting forecast revenue growth rates or long-term inflation rates depending on the nature of the 
cost.  
•	 Pre-tax discount rate of 12.5%, derived from a weighted average cost-of-capital of 11% (2022: 12.0%). 
An increase in the discount rate by 1%, or a decrease in the revenue growth rate by 1% p.a. over the modelled growth period, 
would result in an increase in impairment charge by £482,000 and £774,000 respectively.
No other indicators of impairment were identified in individual CGUs.
For the group of Diagnostics CGUs, where a mandatory impairment assessment is performed due to the presence of goodwill, the 
key assumptions used in the estimation of the value-in-use recoverable amount are as follows:
•	 Modelled growth over a five-year period, except for one CGU as discussed above, with compound annual growth rates ranging 
from 9% to 21%.
•	 Terminal growth rate after the forecast period approximating the long-term average growth rate and ranging from 2.30% to 
4.10% depending on the territory of operation
•	 Gross margins based on historical gross margins achieved, with adjustments to reflect management’s best estimate of future 
achievable margins, ranging from 36% to 64%.
•	 Overhead growth rates reflecting forecast revenue growth rates or long-term inflation rates depending on the nature of the 
cost.  
•	 Pre-tax discount rates ranging from 12.5% to 19.5% derived from weighted average cost-of-capitals of 12.5% to 14.0%.
•	 Management’s best estimate of the increase in future cashflows arising from synergies achievable following the acquisition of 
Coris BioConcept (see Note 26) have been included within that CGU’s value-in-use.
Using these key assumptions, a recoverable amount for the group of CGUs of £32,772,000 was determined, exceeding the 
carrying amount of the group of CGUs by £1,900,000. Reasonably possible changes in key assumptions underlying the recoverable 
amount would cause the group of CGU’s carrying amount to exceed its recoverable amount. An increase in the discount rate 
applied to each CGU within the group of CGUs by 0.5%, or a reduction in the compound annual growth rate by 6% would result in 
the recoverable amount being equal to the carrying amount.

No material provision against trade receivables has been made, the overdue receivables relate to a number of customers for 
whom there is no recent history of default, nor any other indication that settlement will not be forthcoming. The other classes 
within trade and other receivables do not contain impaired assets and are considered to be fully recoverable. 
The Group assesses, on a forward-looking basis, the expected credit losses associated with its debt instruments carried at 
amortised cost. The impairment methodology applied depends on whether there has been a significant increase in credit risk. For 
trade receivables, the Group applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses to be 
recognised from initial recognition of the receivables. The expected loss rates are based on the Group’s historical credit losses and 
current and forward-looking information on factors affecting the Group’s customers. The resulting implied expected credit loss for 
the current financial period is not material.

Unrecognised deferred tax assets
Deferred tax assets have not been recognised in respect of the following items, because it is not probable that future taxable 
profits will be available against which the Group can use the benefits. The unrecognised tax losses do not have an expiry date.
Deferred tax has been measured using the substantively enacted rate due to prevail in the year of reversal.
The comparative period has been restated to retrospectively correct the lack of recognition of a deferred tax asset on losses 
of £2,557,000. The Group historically had significant unrecognised losses, relating to the activities of its subsidiary Avacta Life 
Sciences Limited. Having acquired a profitable subsidiary in October 2022, Launch Diagnostics Limited, a significant deferred tax 
liability was recognised in respect of intangible assets recognised in accordance with IFRS3. This liability should have been offset 
by a deferred tax asset recognised in relation to the historic losses. Further information on the restatement of the prior period is 
included in Note 28.

Respective rights of ordinary and deferred shares
The rights of the ordinary shareholders are dealt with in the Articles of Association of the Company, which are available from 
the Company’s registered office at Unit 20, Ash Way, Thorp Arch Estate, Wetherby, LS23 7FA or from its website, www.avacta.
com. The holders of the deferred shares shall not, by virtue or in respect of their holdings of deferred shares, have the right to 
receive notice of any General Meeting, nor the right to attend, speak or vote at any such General Meeting. Save as required by 
law, the Company need not issue share certificates to the holders of the deferred shares in respect of their holding thereof. The 
deferred shares shall not entitle their holders to receive any dividend or other distribution. The deferred shares shall on a return 
of assets in a winding-up entitle the holders only to the repayment of the amounts so paid up on such deferred shares after 
repayment of the capital paid up on the ordinary shares plus the payment of £10,000,000 per ordinary share. The Company shall 
have irrevocable authority at any time to appoint any person to execute on behalf of the holders of the deferred shares a transfer 
thereof and/or an agreement to transfer the same to such person as the Company determines as custodian thereof, without 
making any payment to the holders thereof, and/or to cancel the same (in accordance with the provisions of the Companies Acts) 
without making any payment to or obtaining the sanction of the holders thereof, and pending such transfer and/or cancellation, to 
retain the certificate for such shares. The Company may, at its option at any time purchase all or any of the deferred shares then 
in issue, at a price not exceeding 1p for each holding of deferred shares so purchased.

Capital reserves
Share premium
The share premium account of £83,220,000 (2022: £62,184,000) arose from the issue of shares at a premium to their nominal 
value less certain allowable costs of issue. This reserve is not distributable.
Other reserve
The other reserve of negative £1,729,000 (2022: negative £1,729,000) arose from the application of reverse acquisition accounting 
principles to the financial statements at the time of the reverse takeover of Avacta Group plc by Avacta Limited. This reserve is not 
distributable.
Translation reserve
The translation reserve comprises all foreign currency differences arising from the translation of the financial statements of foreign 
operations. The transactions recognised within other comprehensive income during the year, from which the translation reserve 
arises, are all items that are or may be reclassified subsequently to profit or loss. This reserve is not distributable.
Reserve for own shares
The reserve for own shares of negative £2,485,000 (2022: negative £2,754,000) arose following the issue of ordinary shares of 10p 
each to Link Market Services Trust Limited as Trustee to the Avacta Group plc SIP (see Note 5) in previous periods. In addition, 
2,782,306 (2022: 2,782,306) ordinary shares of 10p each are held jointly by certain employees, each individually with Avacta Group 
Trustee Limited. This reserve is not distributable. Where ordinary shares have been transferred from Link Market Services Trust 
Limited into the beneficial ownership of employees during the period, these amounts have been transferred to retained earnings, 
this amounted to £270,000 in the period (2022: £206,000).
Retained earnings
Retained earnings arise from the cumulative profits or losses of the Group. The charge and associated credits in respect of 
cumulative share-based payment charges (where appropriate) are also included.

Financial instruments and risk management
Capital management
The Group’s main objective when managing capital is to protect returns to shareholders by ensuring the Group develops such 
that it trades profitably in the foreseeable future. The Group recognises that because it is an early-stage development Group with 
limited current revenues, and significant continued investment that does not support debt within its capital structure, its capital 
structure is largely limited to equity-based capital which the Group uses to finance most of its strategy.
In October 2022, the Group issued senior unsecured convertible bonds (‘the Bonds’) of £55.00 million to a fund advised by Heights 
Capital Ireland LLC, a global equity and equity-linked focused investor. The Bonds were issued at 95% par value with total net 
proceeds of £52.25 million, and accrue interest at an annual rate of 6.5% payable quarterly in arrears. The Bonds contain various 
conversion and redemption features together with embedded derivatives in conjunction with an ordinary host debt liability, 
further details of which can be found in Note 22.
The Group also has credit card debt. Credit card debt is used to finance incidental expenditure, is short term and settled in the 
month following the incurring of the related expenditure. The Group does not have long-term gearing ratio targets.
The Group manages its capital with regard to the risks inherent in the business and the sector within which it operates. It does not 
impact the dividend policy of the Group as the current strategy is to invest capital in the business.
Financial risk management
The Group’s activities expose it to a variety of financial risks: credit risk, liquidity risk and market risk (including foreign currency risk). 
Interest rate risk
The Group continues to manage the cash position in a manner designed to maximise interest income, while at the same time 
minimising any risk to these funds. Surplus cash funds are deposited with commercial banks that meet credit criteria approved by 
the Board, for periods between one and twelve months.
The convertible bond has a fixed interest coupon rate payable of 6.5% per annum. However, due to the embedded derivative 
component, there is an effective interest rate on the debt liability of 113.7% contributing to the ‘Convertible bond – interest 
expense’ charged in the period.
Notes to the Consolidated  
Financial Statements (continued)

Avacta Report and Accounts          2023
Interest rate and currency profile
At 31 December 2023 and throughout the year, the Group maintained cash at bank in the following currencies: The current book 
value of interest-bearing assets and liabilities is as follows: 
Cash at bank attracted interest at floating rates, which were between nil% and 5.00% at 31 December 2023 (2022: nil% and 
2.85%). 
Bank loans are all denominated in euros and attracted interest rates between 1.37% and 4.02% per annum at 31 December 2023.
Credit risk
Management has a credit policy in place and the exposure to credit risk is monitored on an ongoing basis. This policy includes 
restricting the maximum value of cash held with any one financial institution. The Group does not require collateral in respect of 
financial assets. At the balance sheet date, there were no significant concentrations of credit risk. The maximum exposure to credit 
risk is represented by the carrying amount of each financial asset in the balance sheet.
Fair value of financial instruments
At 31 December 2023, the fair value of the Group’s financial assets and liabilities approximates to their carrying amounts as 
disclosed in the Consolidated Statement of Financial Position, with exception of the convertible bond debt element which has an 
effective interest rate of 113.7% (2022: 113.7%) due to the embedded derivative component.
Sensitivity analysis
The Group is not materially exposed to changes in interest or exchange rates at 31 December 2023.
Financial instruments policy
Treasury and financial risk policies are approved by the Board. All instruments utilised by the Group are for financing purposes. 
Short-term deposits are placed for a period of no longer than twelve months with institutions with a ‘superior or strong’ ability to 
repay short-term debt obligations. In order to manage financial exposure between different financial institutions no more than 
£30 million is placed on short-term deposit with any one financial institution.

Convertible bond
In October 2022, the Group issued senior unsecured convertible bonds (‘the Bonds’) of £55 million to a fund advised by Heights Capital 
Ireland LLC, a global equity and equity-linked focused investor. The Bonds were issued at 95% par value with total net proceeds of 
£52.25 million, and accrue interest at an annual rate of 6.5% payable quarterly in arrears.
The Bonds contain various conversion and redemption features. The Bonds have a maturity of five years, and are repayable in 20 
quarterly amortisation repayments, of principal and interest over the five-year term, in either cash or in new ordinary shares at the 
Group’s option. The bondholder also has the option to convert Bonds in full outside of the usual quarterly amortisation repayments, 
which has occurred twice during the period with a total principal amount converted of £3,700,000. For all repayments to date, the 
Group has elected to settle through the issue of shares. The share price underlying the quarterly amortisation repayment is the lower 
of the conversion price (118.75p) or a 10% discount to the volume weighted average price (‘VWAP’) in the five- or ten-day trading period 
prior to conversion date. For other conversions, shares are issued at the conversion price, which may reset downwards at 18 months 
depending on share price performance, subject to a reset price floor of £0.95.
The bond contains embedded derivatives in conjunction with an ordinary host debt liability. The derivative element is measured at 
fair value using a Monte-Carlo option pricing model, which estimates the fair value based on the probability-weighted present value of 
expected future investment returns, considering each of the possible outcomes available to the bondholders. This falls under Level 3 of 
the fair value hierarchy. 
Significant assumptions used in the fair value analysis include the volatility rate. A volatility of 84.7% was used in the determination of the 
fair value of the derivative element. A reduction of 25% would have resulted in a reduction in the fair value at inception by £1,839,000, 
corresponding increases in volatility do not have a significant impact on the valuation. 
The host debt liability is measured at amortised cost, being adjusted to reflect revisions in estimated cashflows arising from early 
conversion events, resulting in an implied interest expense of £14,730,000.
In the comparative period, transaction costs of £3,413,000 were apportioned between the derivative and debt liability components 
according to the relative inception values. This resulted in £2,287,000 of transaction costs being recognised as an expense at acquisition, 
with £1,127,000 adjusted for in the carrying amount of the debt liability at acquisition.

and corresponding to a £3,548,000 increase in the Group’s investment in the associate based on the

Related party transactions
Transactions between the parent company of the Group and its subsidiaries, which are related parties, have been eliminated on 
consolidation. See Note 38 for details of these transactions. 
Provision of services to related parties in the period relate to research and development services provided to an associate of the Group, 
AffyXell Therapeutics Co., Ltd, as set out in Note 23, and to purchase of consulting medical adviser services between the Group and a 
Non-executive Director. These transactions were made on terms equivalent to those that prevail in arm’s length transactions.
AffyXell Therapeutics Co., Ltd is an associate in which the Group has a 25% ownership (2022: 19%). The investment in associate is 
measured using the equity method. The Group has significant influence as a result of material transactions with the entity and the 
provision of essential technical information. AffyXell Therapeutics Co., Ltd was established in 2020 to develop Affimer® proteins 
which will be used for the generation of new cell and gene therapies.
During the year, the investment in associate has increased with the achievement of certain milestones within the collaboration 
resulting in additional issue of equity to the Group. This milestone achievement corresponds to the transfer of an intellectual 
property asset to the associate, representing a downstream transaction between the Group and its associate. The Group’s share 
of the associate’s gain or loss arising from the transaction is therefore eliminated, and instead recognised over a time period 
commensurate to that over which the associate recognises the cost of the asset.

amounts paid in relation to net working capital balances net of financing liabilities. 
In addition, the Group has agreed to pay the selling shareholders additional consideration of one times the sales exceeding €5.5 
million in the year ending 31 December 2023 and 0.9 times the sales exceeding €6.5 million in the year ending 31 December 2024, 
capped at a total of €3.5 million . Based on an assessment of forecast future sales, the fair value of this contingent consideration at 
the acquisition date is £22,000. At 31 December 2023, the contingent consideration estimated has been revised to £nil.
B. Acquisition-related costs
The Group incurred acquisition-related costs of £282,000 on legal fees and due diligence costs. These costs have been included in

Aquisition of subsidiary
 
Coris BioConcept 
On 31 May 2023, the Group acquired 100% of the shares and voting interests in Coris BioConcept SRL (‘Coris’). Coris develops, 
manufactures and markets rapid diagnostic test kits, mainly lateral flow tests, for use by healthcare professionals. Coris is 
ISO13485 certified and markets its products through distributors in Europe, Asia, South America, Africa and Oceania.
For the period from acquisition to 31 December 2023, Coris contributed revenue of £3,270,000 and loss of £278,000 to the 
Group’s results. If the acquisition had occurred on 1 January 2023, management estimates that consolidated revenue would have 
been £24,499,000 and consolidated loss for the year would have been £25,666.000. In determining these amounts, management 
has assumed that the fair value adjustments that arose on the date of acquisition would have been the same if the acquisition had 
occurred on 1 January 2023.

D. Goodwill
Goodwill arising from the acquisition has been recognised as follows:
The goodwill is attributable mainly to the skills and technical talent of Coris’ work-force and the synergies expected to be achieved 
from integrating the company into the Group’s wider Diagnostics business. None of the goodwill recognised is expected to be 
deductible for tax purposes.
Launch Diagnostics
On 21 October 2022, the Group acquired 100% of the shares and voting interests in Launch Diagnostics Holdings Ltd (‘Launch 
Diagnostics’). Launch Diagnostics is a leading independent IVD distributor in the UK, providing immunodiagnostic and molecular 
test products, technical support and maintenance to healthcare providers.
The acquisition of Launch Diagnostics was the first step in an M&A-led growth strategy for the Group’s Diagnostics Division, with 
the vision of building an integrated and differentiated IVD business with global reach servicing professionals and consumers.
For the period from acquisition to 31 December 2022, Launch Diagnostics contributed revenue of £3,971,000 and profit of 
£309,000 to the Group’s results. If the acquisition had occurred on 1 January 2022, management estimates that consolidated 
revenue would have been £27,845,000 and consolidated loss for the year would have been £34,601,000. In determining these 
amounts, management assumed that the fair value adjustments that arose on the date of acquisition would have been the same if 
the acquisition had occurred on 1 January 2022.  
A. Consideration transferred
 
In addition, the Group agreed to pay the selling shareholders additional consideration of 50% of the gross margin on sales 
exceeding £2 million per annum of Launch Diagnostics’ COVID-19 related products for three years capped at £13 million. Based 
on an assessment of forecast future sales, the fair value of this contingent consideration at the acquisition date was £nil. At both 
31 December 2022 and 31 December 2023, the contingent consideration estimated has remained at £nil.
B. Acquisition-related costs
In the year ended 31 December 2022, the Group incurred acquisition-related costs of £712,000 on legal fees and due diligence 
costs. These costs were included in ‘Acquisition-related expenses’.

Discontinued operation
 
On 15 March 2022, the Group sold its entire Animal Health segment (see Note 2).  An up-front payment of £860,000 was received 
with deferred contingent consideration (‘earn-out payment’) of up to £1,433,000. There were associated costs to sell of £181,000. 
The fair value of the contingent consideration has been estimated to be £717,000 as at 31 December 2023 (2022: £717,000). 
The earn-out payment is tiered based on revenues achieved by the combined performance of the Animal Health segment 
and its acquirer. Based on the maximum revenues achieved in any twelve-month period of the three years to 31 December 
2024 (the ‘earn-out period’), the earn-out payment will be nil, £717,000 or £1,433,000. Management’s estimate of fair value is 
an approximation to the expected value, being the value of each payment multiplied by its probability of being achieved. The 
probability of achievement is estimated using information on performance for the period to 31 December 2023 and growth rates 
expected over the remaining earn-out period. In order to achieve an earn-out payment of £717,000, growth rate in revenues of 
4.7% would be required over the remaining earn-out period.
D. Goodwill
Goodwill arising from the acquisition has been recognised as follows:
The goodwill was attributable mainly to the skills and technical talent of Launch Diagnostics’ workforce and the synergies expected 
to be achieved from integrating the company into the Group’s Diagnostics business. None of the goodwill recognised was 
expected to be deductible for tax purposes.

Restatement of comparative information
 
During 2023, the Group identified an error in the 2022 financial statements. On acquisition of Launch Diagnostics in 2022, a 
deferred tax asset should have been recognised in relation to previously unrecognised losses in different taxable entities but 
within the same taxation authority as the Launch Diagnostics UK taxable entity. This asset should have been recognised to the 
extent that the losses offset taxable temporary differences of the Launch Diagnostics UK taxable entity.
This error has been corrected by restating each of the affected financial statement line items in the comparative period. The 
following tables summarise the impacts on the Group’s consolidated financial statements.
In the restated consolidated statement of financial position this leaves a net deferred tax asset relating to the UK taxation 
authority, and a net deferred tax liability relating to the French taxation authority, which cannot be offset against one another.

Accounting policies
Basis of preparation
As used in the financial statements and related notes, the term 
‘Company’ refers to Avacta Group plc.  
These financial statements have been prepared in accordance 
with applicable UK accounting standards, including Financial 
Reporting Standard 102 – The Financial Reporting Standard 
applicable in the United Kingdom and Republic of Ireland (‘FRS 102’), 
and with the Companies Act 2006. The financial statements 
have been prepared on the historical cost basis except for the 
modification to a fair value basis for certain financial instruments 
as specified in the accounting policies below. 
The Company has taken advantage of section 408 of the 
Companies Act 2006 and has not included its own profit and 
loss account in these financial statements. 
The individual accounts of the Company have also adopted the 
following disclosure exemptions: 
•	 The requirement to present a statement of cash flows and 
related notes
•	 The reconciliation of number of shares outstanding from the 
beginning to the end of the period has not been included a 
second time
•	 Key Management Personnel compensation has not been 
included a second time
•	 Certain disclosures required by FRS 102.11 Basic Financial 
Instruments and FRS 102.12 Other Financial Instrument Issues 
in respect of financial instruments not falling within the fair 
value accounting rules of Paragraph 36(4) of Schedule 1
•	 Certain disclosures required by FRS 102.26 Share Based 
Payments
These financial statements have been prepared on a going 
concern basis, the rationale for this assessment is given in Note 1.
Use of judgements and estimates
In preparing the Company financial statements, management 
has made judgements and estimates 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 ongoing 
basis. Revisions to estimates are recognised prospectively.
Information about judgements and estimates made by 
management that have the most significant effects on the 
amounts recognised in the financial statements is given below.
The Directors consider that the key judgements made in 
preparation of the financial statements are:
Going concern - The judgement of whether or not the accounts 
should be prepared on a going concern basis has been 
disclosed in Note 1.
Share-based payments - Judgements arise from the choice of 
inputs to the share option valuation models underlying the 
share-based payment charge, as disclosed in Note 5.
The Directors consider that the assumptions and estimation 
uncertainties at 31 December 2023 that have a significant risk 
of resulting in a material adjustment to the carrying amounts 
and liabilities in the next financial year are: 
Convertible bond derivative liability – Determine the fair value 
of the embedded derivative within the convertible bond, both 
at conversion dates and at the reporting date. See Note 22 for 
further information.
Carrying amount of investments in subsidiaries and amounts 
owed by subsidiary undertakings – Management perform 
an impairment assessment of investments in subsidiaries by 
comparing the carrying amount relevant to each subsidiary with 
the corresponding recoverable amount. In the absence of a 
determinable fair value, the recoverable amount is considered 
to be the value in use of the corresponding cash-generating unit 
forming the basis of the Group impairment testing. 
Management measure impairment of amounts owed by 
subsidiary undertakings by comparing the carrying amount 
with the present value of estimated cash flows discounted at 
the asset’s original effective interest rate.
Where fair value less costs to sell is measurable, for example 
where there is an agreement for sale in place, the aggregate 
carrying amount of investment in subsidiary and intercompany 
receivable is compared to this recoverable amount. Where the 
aggregate carrying amount exceeds the fair value less costs to 
sell, an impairment is first allocated against the investment, with 
any residual impairment recognised against the amount owed 
by the subsidiary. Where the fair value less costs to sell exceed 
the carrying amount, previous impairment losses are reversed 
to increase the carrying amount to the recoverable amount.
Management recognise that there is inherent uncertainty in 
the recoverable amounts based on the value-in use models 
and that the carrying amount of the investment in Launch 
Diagnostics has been impaired to its recoverable amount such 
that an adverse change in assumptions would increase the 
quantum of impairment. A 1% increase in the discount rates 
would result in an increase in the provision against investment 
in subsidiary undertakings by £3,310,000, and a 1% decrease 
in the compound annual revenue growth rate within the 
forecast period of the model would result in an increase in 
provision of £607,000.
Tangible fixed assets
Tangible fixed assets are held at cost less accumulated 
depreciation and impairment charges.
Depreciation is provided at the following annual rates in order 
to write off the cost less estimated residual value, which is 
based on up-to-date prices, of property, plant and equipment 
over their estimated useful lives as follows:
Fixtures and fittings	
    3 to 10 years
Intangible fixed assets
Intangible fixed assets are held at cost less accumulated 
amortisation and impairment charges. Amortisation is 
provided for to write off the cost less estimated residual value 
of intangible assets over the estimated useful lives as follows:
Software                                        3 to 5 years

Avacta Report and Accounts          2023
Investments
Fixed asset investments are stated at cost less accumulated 
provision for impairment where appropriate. The Directors 
consider annually whether a provision against the value of 
investments on an individual basis is required. Such provisions 
are charged to the profit and loss account in the year.
Taxation
The charge for taxation is based on the result for the year 
and takes into account taxation deferred because of timing 
differences between the treatment of certain items for 
taxation and accounting purposes.
Deferred tax is provided for any timing differences between 
the carrying amounts of assets and liabilities for financial 
reporting purposes and the amounts used for taxation 
purposes except when they arise on the initial recognition of 
assets and liabilities that is not a business combination and 
that affects neither accounting nor taxable profits. A deferred 
tax asset is recognised only to the extent that it is probable 
that future taxable income will be available against which an 
asset can be utilised. 
Share-based payments
The grant-date fair value of equity-settled share-based 
payment arrangements granted to employees is generally 
recognised as an expense, with a corresponding increase in 
equity, over the vesting period of the awards. The amount 
recognised as an expense is adjusted to reflect the number 
of awards for which the related service and non-market 
performance conditions are expected to be met, such that 
the amount ultimately recognised is based on the number 
of awards that meet the related service and non-market 
performance conditions at the vesting date. For share-based 
payment awards with market or non-vesting conditions, the 
grant-date fair value of the share-based payment is measured 
to reflect such conditions and there is no true-up for 
differences between expected and actual outcomes.
Employees of subsidiary undertakings are treated as capital 
contributions to subsidiary undertakings from the parent 
company, increasing the cost of investment in subsidiary.
Convertible bond – derivative liability
The Company is party to the derivative element of the 
convertible bond only. The derivative is initially measured at 
fair value, creating a corresponding investment in subsidiary 
reflecting the element of the convertible bond liability borne 
at inception on behalf of the Company’s subsidiary, Avacta 
Finance (Jersey) Ltd. Subsequent changes in the fair value of 
this derivative are recognised through profit or loss. Sensitivity 
analysis has been disclosed in Note 22.This derivative liability 
arises from the future settlement of the bond being through 
the issue of ordinary shares by the Company, in its role as 
Guarantor to the convertible bond. The Company receives 
redeemable preference shares in Avacta Finance (Jersey) 
Ltd in exchange for the issue of such ordinary shares. These 
redeemable preference shares are included within the cost of 
investment, see Note 32.

Investments
*Additions in the year to investments in subsidiary are capital contributions relating to share-based payments to employees of 
subsidiary undertakings.
+Redeemable preference shares of its subsidiary Avacta Finance (Jersey) Ltd are received by the Company in exchange for the 
issue of ordinary shares to settle liabilities arising through conversion of the convertible bond. The paid-up value of the preference 
shares represents the aggregate of the principal and interest being settled. During the period, certain preference shares received 
were subsequently redeemed against the intercompany loan in place between the Company and Avacta Finance (Jersey) Ltd.
During the current year, an impairment assessment of the investment in subsidiaries was undertaken. This assessment involved 
comparing the future discounted cashflows of the subsidiary, or net assets for non-trading subsidiaries, to the carrying value of 
the relevant investment balance. Where the carrying value exceeded this recoverable amount, an impairment was recognised.

Reserves
Share premium
The share premium account of £83,220,000 (2022:

their nominal value less certain allowable costs of issue. This 
reserve is not distributable.
Reserve for own shares
The reserve for own shares of negative £2,485,000 (2022: 
negative £2,755,000) arose following the issue of ordinary 
shares of 10p each to Link Market Services Trust Limited as 
Trustee to the Avacta Group plc SIP (see Note 5) in previous 
periods. In addition, 2,782,306 (2022: 2,782,306) ordinary 
shares of 10p each are held jointly by certain employees, each 
individually with Avacta Group Trustee Limited. This reserve 
is not distributable. Where ordinary shares have been 
transferred from Link Market Services Trust Limited into the 
beneficial ownership of employees during the period, these 
amounts have been transferred to retained earnings, this 
amounted to £270,000 in the period (2022: £206,000).
Retained earnings
Retained earnings arise from the cumulative profits or losses 
of the Group. The charge and associated credits in respect of 
cumulative share-based payment charges (where appropriate)

apply to any such allotment, provided that this power shall be limited to the allotment of equity securities:
in connection with or pursuant to an offer of such securities by way of a pre-emptive offer (as defined below);
(otherwise than pursuant to resolution 10.1 above) up to an aggregate nominal amount of £3,600,000 (being approximately 10% of the issued           
ordinary share capital of the Company as at the date of this notice); and
(otherwise than pursuant to resolutions 10.1 or 10.2 above) up to an aggregate nominal amount equal to 20% of any allotment of equity 
securities or sale of treasury shares from time to time under resolution 10.2 above, such authority to be used only for the purposes of making 
a follow-on offer which the Directors of the Company determine to be of a kind contemplated by paragraph 3 of Section 2B of the Statement of 
Principles on Disapplying Pre-Emption Rights most recently published by the Pre-Emption Group prior to the date of this notice,
and shall expire on the earlier of the date falling six months from the end of the current financial year of the Company and the conclusion of the next 
Annual General Meeting of the Company after the passing of this resolution, save that the Company may, before the expiry of any power contained in 
this resolution, make a further offer or agreement which would or might require equity securities to be allotted after such expiry and the Directors of 
the Company may allot equity securities in pursuance of such offer or agreement as if the power conferred by this resolution had not expired.
For the purpose of resolution 9.2 and this resolution 10: fully pre-emptive offer means a rights issue, open offer or other pre-emptive issue or 
offer to: (i) holders of ordinary shares in proportion (as nearly as may be practicable) to the respective numbers of ordinary shares held by them on 
the record date(s) for such allotment; and (ii) persons who are holders of other classes of equity securities if this is required by the rights of such 
securities (if any) or, if the Directors of the Company consider necessary, as permitted by the rights of those securities, but subject in both cases to such 
exclusions or other arrangements as the Directors of the Company may deem necessary or expedient in relation to fractional entitlements, treasury 
shares, record dates or legal, regulatory or practical difficulties which may arise under the laws of any jurisdiction, the requirements of any recognised 
regulatory body or any stock exchange in any territory or any other matter whatsoever.
11.	
To empower the Directors of the Company (subject to the passing of resolution 9 and in substitution for all existing like powers (other than resolution 
10 above) granted to the Directors of the Company (to the extent that they remain in force and unexercised)) pursuant to sections 570 and 573 of the 
Act to allot equity securities (within the meaning of section 560 of the Act) for cash pursuant to the authority conferred upon them by resolution 9 or 
where the allotment constitutes an allotment of equity securities by virtue of section 560(3) of the Act as if section 561(1) of the Act and sections (1) - (6) 
of sections 562 of the Act did not apply to any such allotment, provided that this power shall be limited to the allotment of equity securities:
up to an aggregate nominal amount of £3,600,000 (being approximately 10% of the issued ordinary share capital of the Company as at the date 
of this notice), such authority to be used only for the purposes of financing (or refinancing, if the authority is to be used within 12 months after 
the original transaction) a transaction which the Directors of the Company determine to be either an acquisition or a specified capital investment 
of a kind contemplated by the Statement of Principles on Disapplying Pre-Emption Rights most recently published by the Pre-Emption Group 
prior to the date of this notice; and
(otherwise than pursuant to resolution 11.1 above) up to an aggregate nominal amount equal to 20% of any allotment of equity securities or sale 
of treasury shares from time to time under resolution 11.1 above, such authority to be used only for the purposes of making a follow-on offer 
which the Directors of the Company determine to be of a kind contemplated by paragraph 3 of Section 2B of the Statement of Principles on 
Disapplying Pre-Emption Rights most recently published by the Pre-Emption Group prior to the date of this notice,
and shall expire on the earlier of the date falling six months from the end of the current financial year of the Company and the conclusion of the next 
Annual General Meeting of the Company after the passing of this resolution, save that the Company may, before the expiry of any power contained in 
this resolution, make a further offer or agreement which would or might require equity securities to be allotted after such expiry and the Directors of 
the Company may allot equity securities in pursuance of such offer or agreement as if the power conferred by this resolution had not expired.

Notice of Meeting Notes
The following notes explain your general rights as a registered shareholder and your right to attend, speak and vote at this Annual 
General Meeting (the 'Meeting') or to appoint someone else to do so on your behalf:
1.	 To be entitled to attend, speak and vote at the Meeting (and for the purpose of the determination by the Company of the number 
of votes they may cast), shareholders must be registered in the Register of Members of the Company at 8.00 p.m. on 24 June 2024. 
Changes to the Register of Members after the relevant deadline shall be disregarded in determining the rights of any person to 
attend, speak and vote at the Meeting.
2.	 Registered shareholders are entitled to appoint another person as a proxy to exercise all or part of their rights to attend, speak and 
vote on their behalf at the Meeting. A shareholder may appoint more than one proxy in relation to the Meeting, provided that each 
proxy is appointed to exercise the rights attached to a different ordinary share or ordinary shares held by that shareholder. A proxy 
need not be a shareholder of the Company. 
3.	 In the case of joint holders, where more than one of the joint holders purports to appoint a proxy, only the appointment submitted 
by the most senior holder will be accepted. Seniority is determined by the order in which the names of the joint holders appear in 
the Company’s Register of Members in respect of the joint holding (the first named being the most senior).
4.	 A vote 'withheld' is not a vote in law, which means that the vote will not be counted in the calculation of votes 'for' or 'against' the 
resolution. If no voting indication is given, your proxy will vote or abstain from voting at their discretion. Your proxy will vote (or 
abstain from voting) as they think fit in relation to any other matter which is put before the Meeting.
5.	 You can vote/appoint a proxy:
•	 by logging on to www.signalshares.com and following the instructions;
•	 LinkVote+ is a free app for smartphone and tablet provided by Link Group (the company's registrar). It offers shareholders the 
option to submit a proxy appointment quickly and easily online, as well as real-time access to their shareholding records.  The 
app is available to download on both the Apple App Store and Google Play, or by scanning the relevant QR code below; 
 
 
 
 
 
 
 
 
•	 if you are an institutional investor you may also be able to appoint a proxy electronically via the Proxymity platform, a process 
which has been agreed by the Company and approved by the Registrar. For further information regarding Proxymity, please 
go to www.proxymity.io. Your proxy must be lodged by 10.30 a.m. on 24 June 2024 in order to be considered valid or, if the 
Meeting is adjourned, by the time which is 48 hours before the time of the adjourned meeting. Before you can appoint a proxy 
via this process you will need to have agreed to Proxymity’s associated terms and conditions. It is important that you read 
these carefully as you will be bound by them and they will govern the electronic appointment of your proxy. An electronic proxy 
appointment via the Proxymity platform may be revoked completely by sending an authenticated message via the platform 
instructing the removal of your proxy vote;
•	 by requesting a hard copy form of proxy directly from the Registrar by email at shareholderenquirires@linkgroup.co.uk or by 
phone on 0371 664 0300. Calls are charged at the standard geographic rate and will vary by provider. Calls outside the UK will 
be charged at the applicable international rate. Lines are open between 9.00 a.m. to 5.30 p.m., Monday to Friday (excluding 
public holidays in England and Wales); or
•	 in the case of CREST members, by utilising the CREST electronic proxy appointment service in accordance with the procedures 
set out below.
6.	 In order for a proxy appointment to be a valid, a proxy form, electronic filing, any CREST Proxy Instructions (as described in note 10 
below) or appointing a proxy via Proxymity must be completed. In each case so as to be received by Link Group by 2.30 p.m. on 24 
June 2024 in accordance with these notes and the notes to the form of proxy.
7.	 If you return more than one proxy appointment, either by paper or electronic communication, the appointment received last by 
Link Group before the latest time for the receipt of proxies will take precedence. Electronic communication facilities are open to all 
shareholders and those who use them will not be disadvantaged. 
8.	 The return of a completed proxy form, electronic filing, any CREST Proxy Instructions (as described in note 10 below) or appointing 
a proxy via Proxymity will not prevent a shareholder from attending the Meeting and speaking and/or voting in person if they wish 
to do so.
Notice of Meeting Notes

9.	 CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for 
the Meeting (and any adjournment of the Meeting) by using the procedures described in the CREST manual (available from www.
euroclear.com). CREST personal members or other CREST sponsored members, and those CREST members who have appointed (a) 
voting service provider(s), should refer to their CREST sponsor or voting service provider(s), who will be able to take the appropriate 
action on their behalf.
10.	 In order for a proxy appointment or instruction made by means of CREST to be valid, the appropriate CREST message (a ‘CREST 
Proxy Instruction’) must be properly authenticated in accordance with Euroclear UK & International Limited's specifications, and 
must contain the information required for such instructions, as described in the CREST manual. The message must be transmitted 
so as to be received by the issuer's agent (ID RA10) by 10.30 a.m. on 24 June 2024. For this purpose, the time of receipt will be 
taken to mean the time (as determined by the timestamp applied to the message by the CREST Application Host) from which the 
issuer's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time any change of 
instructions to proxies appointed through CREST should be communicated to the appointee through other means.
11.	 CREST members and, where applicable, their CREST sponsors or voting service provider(s) should note that Euroclear UK & 
International Limited does not make available special procedures in CREST for any particular message. Normal system timings and 
limitations will, therefore, apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member 
concerned to take (or, if the CREST member is a CREST personal member or sponsored member or has appointed (a) voting service 
provider(s)), to procure that their CREST sponsor or voting service provider(s) take(s) such action as shall be necessary to ensure 
that a message is transmitted by means of the CREST system by any particular time. In this connection, CREST members and, where 
applicable, their CREST sponsors or voting system provider(s) are referred, in particular, to those sections of the CREST manual 
concerning practical limitations of the CREST system and timings. The Company may treat as invalid a CREST Proxy Instruction in 
the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.  
12.	 Any corporation which is a registered shareholder can appoint one or more corporate representatives who may exercise on its 
behalf all of its powers as a registered shareholder, provided that no more than one corporate representative exercises powers in 
relation to the same share.
13.	 As at 29 April 2024 (being the latest practicable date prior to the publication of this document), the Company’s ordinary issued 
share capital consisted of 360,042,104 ordinary shares, carrying one vote each, and 19,327,344 deferred shares, carrying no voting 
rights. Therefore, the total voting rights in the Company as at 29 April 2024 were 360,042,104.
14.	 You may not use any electronic address (within the meaning of section 333(4) of the Act) provided in either this Notice or any related 
documents (including the form of proxy) to communicate with the Company for any purposes other than those expressly stated.
15.	 Under the Articles, resolutions 1 to 9 set out in this Notice are ordinary business, and resolutions 10 to 11 are special business.

Explanation of Resolutions
Ordinary resolutions
Resolutions 1 to 9 are proposed as ordinary resolutions. Each of these resolutions will be passed if more than 50% of the votes 
cast (in person or by proxy) are cast in favour of it.
a.	 Resolution 1: The Directors of the Company ('Directors') are required to present to shareholders at the AGM the audited 
accounts of the Company, the strategic report, and the reports of the Directors and auditor, for the year ended 31 
December 2023.
b.	 Resolution 2: The Directors’ remuneration report is set out in the Company’s Annual Report and Accounts for the year 
ended 31 December 2023. The vote is advisory and the Directors’ entitlement to remuneration is not conditional on it.
c.	 Resolution 3: The Company’s Articles of Association require any Director appointed since the last AGM to retire and seek 
re-appointment. Shaun Chilton was appointed following the last AGM and will seek re-appointment at the AGM. 
d.	 Resolutions 4, 5 and 6: The Company’s Articles of Association require one third of the Directors to retire from office 
each year (or, if their number is not a multiple of three, the number nearest to but not less than one-third). Paul Fry, Mark 
Goldberg and Tony Gardiner are each retiring by rotation and seeking re-appointment at the AGM.  
 
Biographical information for all the Directors standing for re-election is included on page 46 of the Directors’ report in the 
Company’s Annual Report and Accounts. Having considered the performance of and contribution made by each of the 
Directors standing for re-election, the board of Directors (the 'Board') remains satisfied that, and the Chair confirms that, the 
performance of each Director continues to be effective and to demonstrate commitment to the role and as such the Board 
recommends their re-election.
e.	 Resolution 7: Resolution 7 relates to the appointment of BDO LLP as the Company’s Auditor to hold office until the next 
general meeting of the Company at which accounts are laid before the Company. 
f.	 Resolution 8: It is normal practice for shareholders to resolve at the AGM that the Audit Committee decides on the level 
of remuneration of the auditor for the audit work to be carried out by it in the next financial year. The amount of the 
remuneration paid to the auditor for the next financial year will be disclosed in the next audited annual accounts of the 
Company.
g.	 Resolution 9: The Directors may only allot shares or grant rights over shares if authorised to do so by shareholders. The 
Investment Association ('IA') guidelines on authority to allot shares state that IA members will permit, and treat as routine, 
resolutions seeking authority to allot shares representing up to two-thirds of a company’s issued share capital provided 
that any amount in excess of one-third of the company’s issued share capital is applied to fully pre-emptive offers only 
(including open offers and rights issues). Accordingly, resolution 9, if passed, would authorise the Directors under section 
551 of the Companies Act 2006 (the 'Act') to allot new shares or grant rights to subscribe for, or convert any security into, 
new shares (subject to shareholders’ pre-emption rights (unless and to the extent disapplied)): (i) up to a maximum nominal 
amount of £12,001,000; and (ii) up to a maximum nominal amount of £24,002,000 (less the aggregate nominal amount of 
shares or rights granted under (i)) in connection with a fully pre-emptive offer, together representing the IA guideline limit 
of approximately two-thirds of the Company’s issued ordinary share capital (excluding shares held in treasury) as at 29 April 
2024, being the latest practicable date prior to the publication of this document. Passing this resolution will ensure that the 
Directors continue to have the flexibility to act in the best interests of shareholders, when opportunities arise, by issuing 
new shares or granting rights over shares. There are no current plans to issue new shares pursuant to this authority except 
in connection with employee share schemes. 
 
Explanation of Resolutions

Special resolutions 
 
Resolutions 10 to 11 are special resolutions. Each of these resolutions will be passed if 75% or more of the votes cast (in 
person or by proxy) are cast in favour of it.
h.	 Resolutions 10 and 11: The Statement of Principles on Disapplying Pre-Emption Rights most recently published by 
the Pre-Emption Group prior to the publication of this document (the 'Pre-Emption Principles') states that a general 
disapplication of pre-emption rights will likely be supported where a company seeks authority to issue non-pre-emptively 
for cash shares representing: (i) no more than 10% of its issued share capital on an unrestricted basis (being for any 
purpose); and (ii) no more than an additional 10% of its issued share capital to be used for an acquisition or a specified 
capital investment of a kind contemplated by the Pre-Emption Principles. In addition, the Pre-Emption Principles state 
that, in each case, a company may seek further authority to disapply pre-emption rights for up to 2% of its issued share 
capital to be used only for the purposes of a follow-on offer of a kind contemplated by paragraph 3 of Section 2B of the 
Pre-Emption Principles. 
 
Resolution 10 contains a three-part disapplication of statutory pre-emption rights. Other than in connection with a fully 
pre-emptive offer, the power contained in resolution 10 would be limited to a maximum nominal amount of £4,320,500, 
which would equate to 43,205,000 ordinary shares in the capital of the Company, representing approximately 12% of 
the Company’s issued share capital as at 29 April 2024, being the latest practicable date prior to the publication of this 
document. Of the £4,320,500, £720,000 can only be used for the purposes of making a follow-on offer. 
 
Resolution 11 is a further disapplication of pre-emption rights limited to an additional 10% of issued ordinary share 
capital to be used for transactions which the Directors determine to be an acquisition or specified capital investment 
and a further 2% of issued ordinary share capital to be used for making a follow-on offer. This power would be limited 
to a maximum nominal amount of £4,320,500, which would equate to 43,205,000 ordinary shares in the capital of 
the Company, representing approximately 12% of the Company’s issued share capital as at 29 April 2024, being the 
latest practicable date prior to the publication of this document. Of the £4,320,500, £720,000 can only be used for the 
purposes of making a follow-on offer. 
 
If passed, these authorities will expire at the same time as the authority to allot shares given pursuant to resolution 9.
