2023 was a transformational year for Neuren. 
In all three areas of the business, we achieved 
the key planned milestones that generated 
very significant value for all stakeholders.

The approval of DAYBUE™ by the US Food and Drug 
Administration (FDA) in March 2023 as the first ever 
treatment for Rett syndrome was a proud moment for the 
Neuren team. Our partner Acadia launched DAYBUE a month 
later. In our message to you last year, we stated that we 
were confident Acadia was very well placed for successful 
commercialisation. The launch was indeed highly successful 
and 2023 net sales of US$177 million in less than 9 months, 
with Acadia’s guidance for net sales to more than double in 
2024, is an outstanding outcome. We are very encouraged 
by testimonials from families about the impact of treatment.

In July 2023 we expanded our partnership with Acadia 
for DAYBUE from North America to worldwide, following 
a competitive partnering process. Acadia is in a unique 
position of being able to leverage knowledge of all aspects 
of the development, marketing and distribution of DAYBUE. 
The expanded agreement delivered to Neuren US$100 
million up-front and very attractive future economics 
linked to launches and sales in key territories. 

In December 2023 we announced highly encouraging 
results from our Phase 2 clinical trial of NNZ-2591 in 
Phelan-McDermid syndrome. These results exceeded our 
expectations, both in the consistency of the findings and 
the magnitude of improvements seen across clinically 
important aspects of Phelan-McDermid syndrome, 
including communication, behaviour, cognition/learning 
and socialisation. Neuren is currently leading the way in 
striving to achieve the first approved treatment for Phelan-
McDermid syndrome and the team is very excited by 
that prospect.  

We have noted before that Neuren has no cost attached 
to the royalty and milestone revenue we receive from 
Acadia, which therefore flows straight into pre-tax profit.  
The impact of this was evident in our financial results for 
2023, the highlight of which was profit after tax of $157 
million. This reflected revenue from Acadia of A$232 million, 
comprising royalty of A$27 million, a milestone payment 
of A$59 million and A$146 million from the expanded 
worldwide agreement.

Neuren was promoted into the S&P/ASX 200 index in 
September 2023 and was the best performing ASX 200 
stock in 2023, with a share price increase of 214%. We 
now have many more institutional shareholders and a 
high level of interest and engagement from the financial 
markets community. We continue to seek higher interest 
and investment, both in Australia and overseas, assisted by 
a wide range of intermediaries. In October 2023, Neuren was 
presented with the 2023 Australian Growth Company of the 
Year Award for Health and Life Sciences.

VALUES

We are determined and creative to break 
through barriers

We harness the power of collaboration and 
different perspectives

We recognise the importance of all 
stakeholders and endeavour to use 
financial resources efficiently

The Neuren team is far from complacent following the 
success of the last two years. We are acutely aware that 
it follows, and has been built on, a ten-year journey since 
our first clinical trial in Rett syndrome and that many loyal 
and committed shareholders have accompanied us on that 
journey. The experience we have gained on the ten-year 
journey is extremely valuable. Everything we have learnt 
from the development of trofinetide in Rett syndrome is 
directly relevant to our development of NNZ-2591 in other 
neurodevelopmental disorders, led by Phelan-McDermid 
syndrome. We believe that this and the connection of both 
drugs to IGF-1 enhances the risk profile of the NNZ-2591 
programs.

There is so much more to achieve and 2024 is another very 
important year for the business. We look forward to the 
continued progress of DAYBUE, both in the US and in other 
territories. We await the results of the Phase 2 trials of NNZ-
2591 for Pitt Hopkins syndrome in Q2 2024 and for Angelman 
syndrome in Q3 2024. In the meantime, the team is highly 
focused on advancing the Phelan-McDermid syndrome 
program. We are diligently preparing for an End of Phase 
2 Meeting with the FDA and are commencing manufacture 
of the drug supplies that will be required for a Phase 3 
program. We are also actively exploring further potential 
indications for NNZ-2591 and will say more about this as our 
assessment progresses.

Neuren is in a very strong financial position, with cash 
and short-term investments of more than A$200 million 
and the ongoing revenues from DAYBUE. This supports 
our commitment to achieving the best outcome for 
shareholders by pursuing value-adding opportunities to 
their fullest potential. For NNZ-2591, we will continue to 
evaluate all options to achieve this as the events of this 
year unfold.

We are grateful to our shareholders, both longstanding 
and new, and all the patient communities for the support 
that is so critical for our success. We commend and thank 
the Neuren team for their achievements and dedication, 
assisted by a range of development partners.

NEUREN’S GROUND -BREAKING THER APIES 
Neuren focuses on developing treatments for debilitating 
neurodevelopmental disorders that emerge in early 
childhood and stem from problems in brain development 
which lead to a wide range of serious issues affecting nearly 
every aspect of life. These neurodevelopmental disorders 
have severe life-long impact on the patients and their 
families. Each neurodevelopmental disorder is caused 
by a different genetic mutation, but in many cases, they 
share similar symptoms and the common characteristic 
of impaired connections and signalling between brain cells. 

Neuren currently has two novel patented drugs, trofinetide 
and NNZ-2591, which potentially have broad utility in 
the treatment of neurological disorders. Both drugs are 
synthetic analogues of important molecules that occur 
naturally in the brain, aiming to improve the impaired 
connections and signalling, meaning that the drug’s target 
is to have a broad impact on the disorder rather than aiming 
to treat one symptom. Both drugs can be administered 
orally in a patient-friendly liquid dose.

A critical feature of Neuren’s work to develop therapies 
for each of these disorders is close collaboration with the 
leading specialist physicians and with the well-organised 
patient advocacy organisations. 

THE IMPORTANCE OF ORPHAN DRUG 
DESIGNATION
The US Food and Drug Administration (FDA) and European 
Medicines Agency (EMA) have both granted Orphan Drug 
designation for trofinetide in Rett syndrome and Fragile X 
syndrome and for NNZ-2591 in each of Phelan-McDermid, 
Angelman and Pitt Hopkins syndromes. The FDA has also 
granted orphan drug designation for NNZ-2591 in Prader-
Willi syndrome.

Orphan Drug designation is a special status that the 
regulators may grant to a drug to treat a rare disease 
or condition. Amongst other incentives, Orphan Drug 
designation qualifies the sponsor of the drug for exclusivity 
periods during which the regulators will not approve a 
generic competitor product. These marketing exclusivity 
periods are extremely valuable for the commercialisation 
of Orphan Drugs. They provide additional protection, along 
with patents, against generic competitors and potentially 
can continue to provide protection after patent expiry. 
The exclusivity periods after marketing authorisation of 
products approved for pediatric use are 7.5 years in the 
United States and 12 years in the EMA region. Japan, South 
Korea and Taiwan also have Orphan Drug programs.

4

Neuren Pharmaceuticals Limited Annual Report 2023O P E R AT I N G   R E V I E W

C O N T I N U E D

As well as the exclusivity periods, Orphan Drugs have many 
other commercial advantages compared with existing 
markets that have apparently attractive large sales in which 
established products and companies have to be displaced. 
The serious and urgent unmet need results in a more 
supportive regulatory and pricing environment and strong 
engagement from the patient community and leading 
physicians. Historical data indicates a higher probability 
of achieving regulatory approval and the potential 
for immediate access to known patients means that a large 
sales organisation is less important. 

In short, the Orphan Drug business model targets a 
leadership position in markets with urgent need, at an 
attractive price and with a higher probability of getting 
to market.

The neurodevelopmental disorders that Neuren is aiming 
to treat are “rare diseases”, however they are not “ultra-
rare”, and in each disorder there are tens of thousands of 
potential patients.

COMMERCIAL EXCLUSIVIT Y
In addition to the primary protection of the important 
exclusivity periods from Orphan Drug designation explained 
above, Neuren has additional commercial protection from 
issued patents and pending patent applications, which 
extend as far as 2041. Since trofinetide and NNZ-2591 
are new chemical entities, following the first marketing 

authorisation for each drug, the term of one patent 
may potentially be extended by up to 5 years in many 
countries, including the United States, Europe and Japan.

TROFINETIDE FOR RETT SYNDROME

Successful launch of DAYBUE™ (trofinetide) 
in the United States 
In March 2023, Neuren’s partner for trofinetide, Acadia 
Pharmaceuticals (NASDAQ: ACAD), received US Food 
and Drug Administration (FDA) approval of DAYBUETM 
(trofinetide) for the treatment of Rett syndrome in 
adult and pediatric patients two years of age and older. 
On 17 April 2023, Acadia Pharmaceuticals launched 
DAYBUE™ (trofinetide) in the United States as the first 
approved treatment for Rett syndrome. 

Adoption of DAYBUE in the diagnosed Rett syndrome 
population has been faster than expected, with 
approximately 860 patients on DAYBUE at the end of 
February 2024. Caregivers and physicians have continued 
to report meaningful improvements in patients and the 
high demand has been well supported by access from 
Medicaid and private health insurance payors. In the 
United States there are approximately 5,000 diagnosed 
Rett syndrome patients and prevalence studies suggest 
the total number of patients may be 6,000 to 9,000.

Acadia reported net sales of US$177 million for 2023 and 
has provided guidance for net sales in 2024 of between 
US$370 million and US$420 million.

A characteristic of all long-term medicines is that not all patients who commence treatment will persist with treatment. 
Furthermore, for patients and caregivers, adjusting to a novel treatment regimen can take time, especially when it is the first 
treatment ever to become available. The number of patients commencing treatment and the proportion that persist with 
treatment long-term are key factors in the sales outcome. Acadia has provided detailed metrics for real world persistency since 
launch, which continues to outperform the clinical trial experience and has improved as new patient cohorts are added. The 
chart below shows the data reported in Acadia’s Q4 earnings call presentation in February 2024. The real world persistency has

Growing sustainable income to Neuren
In June 2023, Neuren received from Acadia a milestone payment of US$40 million earned following the first commercial sale of 
DAYBUE (trofinetide). 

Neuren is eligible to receive ongoing royalties on net sales of trofinetide in North America, plus milestone payments of up to 
US$350m on achievement of a series of four thresholds of total annual net sales, plus one third of the market value of the Rare 
Pediatric Disease Priority Review Voucher that was awarded to Acadia by the FDA upon approval of the New Drug Application 
(NDA)”, to be paid when Acadia sells or uses the voucher. Neuren estimates the value of its one third share as US$33 million. 
No royalties or similar costs are payable by Neuren to third parties, which means Neuren’s revenue from Acadia will flow 
through to pre-tax profit. The royalty rates and sales milestone payments are related to the total amount of annual net sales of 
trofinetide in all indications in North America, as set out in the following tables:

SEC Filings section of Acadia’s website.

Following the expansion of the partnership with Acadia for trofinetide to worldwide, Acadia is now advancing in key markets 
outside North America. 

For Europe, Acadia is engaging with the European Medicines Agency (EMA) in Q1 2024, with a potential Marketing Authorisation 
Application filing in H1 2025. For Japan, Acadia is engaging with the regulator, Pharmaceuticals and Medical Devices Agency 
(PMDA) in 2024.

There is urgent unmet need for a treatment for Rett syndrome around the world, evidenced by communications received from 
families, patient support groups and physicians. The estimated number of potential patients and currently identified patients 
is shown in the table below. Neuren expects rates of diagnosis to increase with greater awareness and accelerate with the 
availability of a treatment.

         About Rett syndrome
Rett syndrome is a seriously debilitating and life-threatening neurological disorder. It is first recognized in infancy and 
seen predominantly in girls, but can occur very rarely in boys. At diagnosis, Rett syndrome has often been misdiagnosed as 
autism, cerebral palsy, or non-specific developmental delay. Most cases of Rett syndrome are caused by mutations on the 
X chromosome on a gene called MECP2. Rett syndrome strikes all racial and ethnic groups and has been estimated to occur 
worldwide in 1 of every 10,000 to 15,000 female births, causing problems in brain function that are responsible for cognitive, 
sensory, emotional, motor and autonomic function. These problems can include learning, speech, sensory sensations, mood, 
movement, breathing, cardiac function, and even chewing, swallowing, and digestion. Rett syndrome symptoms appear after 
an early period of apparently normal or near normal development until six to eighteen months of life, when there is a slowing 
down or stagnation of skills. A period of regression then follows, with loss of communication skills and purposeful hand use, 
loss or impairment of walking, and the onset of stereotypic hand movements. Other problems frequently include seizures and 
erratic breathing patterns, an abnormal side-to-side curvature of the spine (scoliosis), and sleep disturbances.

All four programs have been granted Orphan Drug designation by the US Food and Drug Administration (FDA) and are being 
developed under Investigational New Drug (IND) applications. In designing and executing the NNZ-2591 development program, 
Neuren has been able to leverage the extensive and highly relevant experience the management team has gained from the 
trofinetide Rett syndrome program across manufacturing, non-clinical, clinical and regulatory.

Phase 2 clinical trials 
Phase 2 clinical trials are being conducted in all four indications. The open label trials are each enrolling up to 20 children to 
examine safety, tolerability, pharmacokinetics and efficacy over 13 weeks of treatment with NNZ-2591. All subjects receive 
NNZ-2591 as an oral liquid dose daily, with escalation in two stages up to the target dose during the first 6 weeks of treatment, 
subject to independent review of safety and tolerability data. The study begins with 4 weeks of observation to thoroughly 
examine baseline characteristics prior to treatment, against which safety and efficacy are assessed for each child. This is 
followed by the treatment period of 13 weeks. A follow-up assessment is made 2 weeks after the end of treatment.

The overall aim of these first trials is to expedite the generation of data that will enable the subsequent trials to be designed 
as registration trials. In 2023 positive results were achieved in the Phelan-McDermid syndrome trial and enrolment was 
completed in both the Pitt Hopkins and Angelman syndrome trials. Top-line results are anticipated for Pitt Hopkins in Q2 2024 
and for Angelman in Q3 2024.

Positive results in Phelan-McDermid syndrome Phase 2 trial
In December 2023, Neuren announced positive top-line results from the Phase 2 clinical trial of NNZ-2591 in children with 
Phelan-McDermid syndrome. 

NNZ-2591 was well tolerated and demonstrated a good safety profile. There was only one serious treatment emergent adverse 
event (TEAE) of gastroenteritis, which was not related to study drug and occurred during the safety follow-up period after 
end of treatment. Three subjects discontinued due to TEAEs, two testing positive for COVID-19 and one due to seizures that 
were not related to study drug. No clinically significant changes in laboratory values, electrocardiogram (ECG) or other safety 
parameters were observed during treatment. TEAEs occurring in two or more subjects are listed in the following table:

Significant improvement was observed by both clinicians and caregivers from treatment, across multiple efficacy 
measures. Improvements were consistently seen across many of the core PMS characteristics. The results for the global 
efficacy measures rated by both clinicians and caregivers showed a level of improvement typically considered clinically 
meaningful. 16 out of 18 children showed improvement measured by the Clinical Global Impression of Improvement (CGI-I), 
an assessment by the clinician of the child’s overall status compared with baseline. The mean CGI-I score was 2.4. 10 children 
received a score of either 1 (“very much improved”) or 2 (“much improved”). 15 out of 18 children showed improvement 
measured by the Caregiver Overall Impression of Change (CIC), an assessment by the caregiver of the child’s overall status 
compared with baseline. The mean CIC score was 2.7. Seven children received a score of either 1 (“very much improved”) 
EEffffiiccaaccyy  eennddppooiinnttss  ssuummmmaarryy
or 2 (“much improved”). CGI-I and CIC are 7 point scales in which scores of 1, 2 or 3 indicate improvement.

Preparation for Phase 3
In order to expedite the overall development plan, in parallel with conducting the Phase 2 trials Neuren has been executing the 
additional development work required to be ready for Phase 3 development. Non-clinical toxicity studies to support longer 
clinical trials and commercial use of the product have been completed. Optimisation and scale-up of the drug product and 
drug substance manufacturing arrangements are well advanced, with manufacturing of supplies for Phase 3 trials scheduled 
in 2024.

31

Neuren plans to discuss proposals for Phase 3 development in Phelan-McDermid syndrome with the FDA during 2024.

Phelan-McDermid syndrome has an overwhelming unmet medical need
Phelan-McDermid syndrome (PMS) is caused by a deletion or other change in the 22q13 region of chromosome 22, which 
includes the SHANK3 gene, or a mutation of the gene. PMS is also known as 22q13 deletion syndrome. The SHANK3 gene codes 
for the shank3 protein, which supports the structure of synapses between nerve cells in the brain. PMS has severe quality of life 
impacts for those living with the syndrome, as well as parents and siblings. There are no approved treatments for PMS despite 
its severely debilitating impact.

The estimated prevalence of PMS is 1% of people diagnosed with autism, or between 1 in 8,000 and 1 in 15,000 males and 
females. It has historically been underdiagnosed, but this is changing with rising awareness and enhancement of genetic 
testing technologies. In November 2022, an important Externally-Led Patient Focused Drug Development (EL-PFDD) Meeting 
was held, in order for the FDA and other key stakeholders to hear directly from patients, their families, caregivers, and patient 
advocates about the impact PMS has on patients’ daily lives. The meeting content was collated in a “Voice of the Patient” 
report. In 2023 for the first time an International Classification of Disease (ICD) code was assigned to PMS.

From the Phelan-McDermid Syndrome Voice of the Patient Report:

“ PMS has an overwhelming unmet medical need. There are no FDA approved treatments for PMS despite 
its severely debilitating manifestations. Parents and caregivers are open to trying almost anything to try 
to relieve their child’s suffering; most have tried an incredibly high number of treatments and approaches 
for symptom management, with very little success. Some received medications that caused more harm 
than good.”

“ PMS has severe quality of life impacts on those living with the disease, as well as on parents and 
siblings. Most activities of daily life, including communicating needs or wants, self-care (bathing, dressing, 
toileting) and socializing with peers/siblings are affected. Most individuals living with PMS rely on their 
parents and caregivers for all their daily needs, and many require 24-hour care.”

Strong foundations built for NNZ-2591
Neuren has meticulously built strong foundations to enable clinical development of NNZ-2591 in multiple indications. 

Clear and consistent efficacy in mouse models of all four disorders

The studies in these models compared normal mice (“wild type”) and mice with a disrupted gene (“knockout”). The knockout 
mice exhibit behavioural and biochemical deficits that mimic each disorder in humans. The wild type mice and the knockout 
mice were each treated with placebo and NNZ-2591. In all four models, treatment with NNZ-2591 for 6 weeks eliminated all 
the deficits so that the knockout mice were indistinguishable from the wild type mice. In the Prader-Willi syndrome model, 
treatment with NNZ-2591 also normalized fat mass (obesity), insulin levels and IGF-1 levels. Treatment had no impact on the 
wild type mice which is important from a safety point of view.

Following review of the data from the mouse models and the mechanistic rationale for treatment, FDA granted Orphan Drug 
designation for NNZ-2591 in each of the four disorders.

OPTIMUM DOSE IN MOUSE MODEL OF PHELAN-
MCDERMID
Optimum dose identified

In the Phelan-McDermid syndrome model, the effect of four escalating dose levels was investigated. The results of this dose 
ranging study are shown in the charts below. They were consistent across all 8 behavioral tests and the incidence of seizures, 
demonstrating that the second highest dose was the optimum dose level in the mouse model. Comparison with human 
pharmacokinetic data from the Phase 1 clinical trial has informed the equivalent human dose for the Phase 2 trials in patients.

A further observation was that the optimum dose in this 6-week study showed better efficacy than the same dose in an earlier 
study for 3 weeks, indicating that efficacy increases with treatment duration. In the Phase 2 trials Neuren is testing treatment 
with NNZ-2591 for 13 weeks.

CORRECTING IMPAIRED SIGNALING IN NEURONS

Effects on biochemistry and brain cell structure confirmed

Biochemical testing in the Phelan-McDermid model showed that the abnormal length of dendritic spines between brain 
cells, the excess activated ERK protein (pERK) and the depressed level of IGF-1 in the knockout mice were all normalised after 
treatment with NNZ-2591, as shown in the charts below.

Blood-brain barrier penetration confirmed

As well as very high oral bioavailability, good penetration of the blood-brain barrier by NNZ-2591 has been demonstrated in 
a rodent study. A single dose was administered at 2 dose levels, with the high dose twice the low dose. The concentration of 
NNZ-2591 in the blood and cerebrospinal fluid was determined after 1.5 hours and again after 4 hours. The amount in the brain 
tissue was also measured after 4 hours. In each case the concentration was approximately proportional to the dose and after 
4 hours the concentration in blood and brain tissue was approximately equivalent.

Large scale manufacturing process developed

Neuren has successfully developed a proprietary process for manufacturing drug substance at large scale with exceptional 
purity and high yield.

Positive Phase 1 clinical trial results

Neuren completed a Phase 1 clinical, in which twice daily oral dosing of NNZ-2591 for seven days was safe and well tolerated in 
healthy volunteers at doses expected to be within the effective therapeutic range. This was an important milestone for NNZ-
2591 to be able to move forward to Phase 2 clinical trials in patients.

The primary objective was to evaluate safety and tolerability, with a secondary objective to evaluate pharmacokinetic 
parameters. No Serious Adverse Events (SAEs) were reported. All reported Adverse Events (AEs) were mild or moderate and 
resolved during the trial. There were no clinically significant findings from safety laboratory tests, vital signs, or cardiac tests. 
In the cohorts dosed for seven days, the most common AE reported was drowsiness.

Other indications
The mechanism of action of NNZ-2591 is relevant for many other neurodevelopmental synaptopathies and potential additional 
indications are currently being assessed. 

As part of the expanded global partnership with Acadia signed in July 2023, Neuren granted Acadia exclusive worldwide 
licence for NNZ-2591 solely in Rett syndrome and Fragile X syndrome, which enabled coordinated global development and 
removed restrictions on Neuren for NNZ-2591 in those two indications. Neuren retains worldwide rights to NNZ-2591 in all other 
indications.

Potential future payments to Neuren related to NNZ-2591 in Rett syndrome and Fragile X syndrome are identical to 
the payments for trofinetide in each of North America and outside North America. Acadia is responsible for all costs of 
development and commercialization in those two indications. 

THE SCIENCE BEHIND NEUREN’S PRODUCTS
Trofinetide (also known as NNZ-2566) and NNZ-2591 are synthetic analogues of glypromate (“GPE”) and cyclic glycine-proline 
(“cGP”) respectively, each of which occurs naturally in the brain and is involved in the biology of IGF-1, which is a growth factor 
stimulated by growth hormone. In the central nervous system, IGF-1 is produced by both of the major types of brain cells – 
neurons and glia. IGF-1 in the brain is critical both for normal development and to maintain or restore the biological balance 
required for normal functioning. During development, the brain and the cells that comprise it change rapidly and in complex 
ways. IGF-1 and its metabolites play a significant role in regulating these changes. In the mature brain, these molecules play an 
important role in responding to disease, stress and injury. 

Trofinetide and NNZ-2591 mimic the function of the natural molecules in the brain, however each drug is designed to have a 
longer half-life in circulation, be suitable for use as an oral medication, more readily cross the blood brain barrier and have 
better stability for longer and easier storage and shipping.

Whereas many drugs typically exert a specific effect on a specific target related to one symptom, trofinetide and NNZ-2591 
exert diverse effects which can help to control or normalise abnormal biological processes in the brain. 

Many neurological conditions share four common, underlying pathological features:

1. Inflammation
Inflammation in the brain (neuroinflammation) is perhaps the most common pathological feature of neurological disorders. 
Much of it is the result of excess production of molecules called inflammatory cytokines. These are prominent in brain injuries, 
neurodevelopmental disorders such as Rett syndrome, neurodegenerative diseases like Alzheimer’s and even so-called 
“normal” aging. 

Neuroinflammation places significant stress on brain cells. Stress can disrupt normal cellular processes such as information 
signalling, increase energy requirements beyond the ability of the cells to meet their metabolic needs, and disturb electrical 
functions which can lead to seizures and other abnormalities and even result in premature cell death.

2. Over-activation of microglia
Microglia are the resident immune cells in the brain. Once thought to serve primarily a sentinel function – responding to 
infection and damaged cells by surrounding and removing them – it is now known that they play a central role in maintaining 
synapses during development and in mature brains by pruning dendrites, the many small extensions of neurons that form 
synapses. Microglia are also a key source of IGF-1. Due to this wide-ranging maintenance function, they have appropriately 
been referred to as the “constant gardeners” of the brain.

Microglia are not only activated in response to infection and injury, they also are activated by inflammation. In this activated 
state, they not only lose their ability to effectively perform their normal function in synaptic maintenance but also produce 
more inflammatory cytokines which can further compound the damage to neurons and other brain cells.

Resting Microglial Cells

3. Dysfunction of synapses
Neurons communicate with each other by chemical and electrical signals transmitted via synapses. Normal synaptic function 
is essential for healthy brain function and underlies memory, cognition, behaviour and other brain activities. Normal synaptic 
function requires that the dendrites (the branches on the neurons) which form synapses are appropriately formed as well as 
that excitatory and inhibitory signals are kept in balance. 

When dendritic structure and synaptic signalling are abnormal, virtually all brain activities can be negatively 
impacted. Synaptic dysfunction has been identified as a core feature of many conditions including acute brain injury, 
neurodevelopmental disorders and neurodegenerative diseases. 

4. Reduced levels of IGF-1
IGF-1 levels in the brain have been reported to be depressed in a number of conditions, which means that the critical role of 
IGF-1 in maintaining and repairing brain cells and synapses is impaired. 

The aim of treatment with Neuren’s drugs is to restore the natural balance of brain function by:
 – reducing inflammation
 – restoring the normal functioning of microglia
 – improving the dendritic structure of synapses
 – normalising the levels of IGF-1 in the brain

Financial commentary
The consolidated profit after tax attributable to equity 
holders of the Company for the year ended 31 December 
2023 was A$157.1 million compared with A$0.2 million 
in 2022. Revenue of A$231.9 million was received under 
the licence agreement with Acadia (2022: A$14.6 million). 
This includes A$59.4 million for the first commercial sale 
milestone, an upfront of A$145.7 million under the expanded 
global licence agreement with Acadia and A$26.8 million 
from quarterly royalty income. Other income includes 
interest income of A$5.7 million (2022: A$0.4 million) and 
foreign exchange gains of A$2.4 million (2022: A$1.2 million).

There was an increase of A$14.1 million in research and 
development costs, due to higher expenditures in 2023 for 
the NNZ-2591 Phase 2 clinical trials and the foundational 
work to prepare for Phase 3 development of NNZ-2591 
across multiple indications. There was also an increase in 
corporate and administrative costs of A$2.5 million, mainly 
due to higher employee benefits and share-based payments 
expense. In addition, a loss of A$2.2 million on the fair value 
of outstanding forward contracts to sell Australian dollars 
and buy US dollars was recognised at 31 December 2023 
(2022: A$0.7 million).

The net income tax expense recognised for the year ended 
31 December 2023 was A$48.1 million (2022: nil). After 
utilising Australian carried forward tax losses and the 
expectation of offsetting the 5% withholding tax paid to 
the US Internal Revenue Service in relation to the milestone 
payments, Neuren has recognised a current tax liability of 
A$37.1 million.

Total cash and short-term investments at 31 December 
2023 were A$228.5 million (2022: A$40.2 million). Net cash 
received from operating activities was A$184.9 million (2022: 
A$3.6 million). The increase of A$181.3 million was primarily 
due to the receipt of A$221.0 million (2022: A$15.9 million) 
from Acadia for the first commercial sale milestone payment 
of US$40 million, the up-front payment of US$100 million 
under the expanded global licence agreement for trofinetide 
and receipt of quarterly royalty payments. This was offset by 
higher payments to other suppliers of A$24.6 million (2022: 
A$11.3 million) due to higher expenditures for the NNZ-2591 
Phase 2 clinical trials and the foundational work to prepare 
for Phase 3 development of NNZ-2591 across multiple 
indications. Withholding tax of A$11.8 million was paid to 
the US Internal Revenue Service by Acadia on Neuren’s 
behalf. This will be offset against Neuren’s Australian tax 
liability. Net cash from financing activities for 31 December 
2023 was A$3.6 million (2022: nil), comprising proceeds 
received on conversion of loan funded shares and exercise 
of share options.

Following the receipt of the first commercial sale milestone, 
up-front payment under the expanded global licence 
agreement for trofinetide and quarterly royalty payments, 
Neuren is holding more funds than are required to meet 
currently forecast short-term cash commitments. As a 
result, Neuren has classified A$211.4 million of short-term 
deposits as Short-term Investments.

Neuren Pharmaceuticals Limited Annual Report 2023CO R P O R AT E   G O V E R N A N C E

Neuren’s board of directors (“Board”) aims to ensure that 
the Company and its subsidiaries (the “Group”) operates 
with a corporate governance framework and practices that 
promote an appropriate governance culture throughout 
the organisation and that are relevant, practical and cost-
effective for the current size and stage of development of 
the business.

This Statement has been approved by the Board and 
provides a description of the framework and practices 
that are in operation at the Reporting Date, laid out 
under the structure of the ASX Listing Rules and the 
Corporate Governance Principles (the “Principles”) and 
Recommendations (the “Recommendations”) 4th Edition.

PRINCIPLE 1.  L AY SOLID FOUNDATIONS 
FOR MANAGEMENT AND OVERSIGHT
The Board is responsible for the overall corporate 
governance of the Group. The Board acts on behalf of and 
is accountable to the shareholders. The Board seeks to 
identify the expectations of shareholders as well as other 
regulatory and ethical expectations and obligations. The 
Board is responsible for identifying areas of significant 
business risk and ensuring mechanisms are in place to 
manage those risks adequately. In addition, the Board sets 
the overall strategic goals and objectives, and monitors 
achievement of goals.

The Board appoints the principal executive officer, 
currently the Chief Executive Officer. The Board has 
delegated the responsibility for the operation and 
administration of the Group to the Chief Executive Officer 
and senior management. The Board ensures that the 
management team is appropriately qualified to discharge 
its responsibilities. 

The Board ensures management’s objectives and activities 
are aligned with the expectations and risks identified by 
the Board through a number of mechanisms including the 
following:

 – establishment of the overall strategic direction and 

leadership of the Group;

 – approving and monitoring the implementation by 

management of the Group’s strategic plan to achieve 
those objectives;

 – reviewing performance against its stated objectives, 

by receiving regular management reports on business 
situation, opportunities and risks;

 – monitoring and review of the Group’s controls and 
systems including those concerned with regulatory 
matters to ensure statutory compliance and the highest 
ethical standards; and

 – review and adoption of budgets and forecasts and 
monitoring the results against stated targets.

The Board sets the corporate strategy and financial targets 
with the aim of creating long-term value for shareholders.

In accordance with Recommendation 1.2, the Board 
undertakes appropriate checks before appointing a new 
director, or putting forward to shareholders a candidate 
for election and provides shareholders with all material 
information in its possession relevant to a decision on 
whether or not to elect or re-elect a director.

The Group has a written agreement with each director and 
senior executive, setting out the terms of their appointment, 
in accordance with Recommendation 1.3. The Company 
Secretary is accountable directly to the Board on all matters 
to do with the proper functioning of the Board, in accordance 
with Recommendation 1.4.

At this stage of the Group’s development, considering the 
very small size of the workforce and the specialist nature 
of most positions, the Board has chosen not to establish 
a formal diversity policy or formal objectives for gender 
diversity, as recommended in Recommendation 1.5. The 
Group does not discriminate on the basis of age, ethnicity, 
religion, gender or sexuality and when a position becomes 
vacant the Group seeks to employ the best candidate 
available for the position. At 31 December 2023 there 
were four male and two female directors. Five of the ten 
senior executives were female. The Group had twenty-four 
employees and consultants, of which thirteen were female. 

In accordance with Recommendation 1.6, there is a process 
to evaluate periodically the performance of the Board, 
its committees and individual directors. A performance 
evaluation was undertaken by an independent external 
party, with the process commencing during 2023. The final 
report with recommendations was presented to the Board 
in February 2024. 

In accordance with Recommendation 1.7, there is a process 
for the Board to evaluate periodically the performance of the 
Chief Executive Officer and for the Chief Executive Officer to 
evaluate periodically the performance of senior executives. 
The evaluation of the Non-Executive Chair is part of the 
board performance evaluation process. For the evaluation 
of senior executives, an individual discussion is held after 
each senior executive complete a qualitative questionnaire, 
covering past individual and team achievements and 
challenges, as well as forward-looking outcomes and areas 
of personal focus. Performance evaluations were undertaken 
during early 2024, in relation to the performance of the 
senior executives in 2023. The performance evaluations 
were postponed until after the announcement of top-line 
results from the Phase 2 clinical trial of NNZ-2591 in Phelan-
McDermid syndrome in late December 2023, given the 
importance of that milestone.

PRINCIPLE 2.  STRUCTURE THE BOARD TO BE EFFECTIVE AND ADD VALUE
The Board has not considered it necessary or value-adding to establish a separate Nomination Committee (Recommendation 
2.1). The selection, appointment and retirement of directors is considered by the full Board, within the framework of the skills 
matrix described below. The Board may also engage an external consultant where appropriate to identify and assess suitable

 Given the length of his tenure, in accordance with the Recommendations the Board has considered the nature of the relationships 
of Trevor Scott with management and substantial shareholders and has concluded that he remains independent. 

Jon Pilcher is not considered independent due to his executive role.

There is a majority of independent directors in accordance with Recommendation 2.4. The chair is independent and the chair 
and chief executive officer roles are separate (Recommendation 2.5). The directors believe that the structure and membership 
profile of the Board has provided and continues to provide the maximum value to the business at its stage of its development. 

In accordance with Recommendation 2.6, the Company has a program for inducting new directors and provides appropriate 
professional development opportunities for directors to develop and maintain the skills and knowledge needed to perform 
their role as directors effectively.

Whistleblower Policy are to be reported to the Board.

The Group’s Anti-bribery and Corruption is available on 
the Company website (Recommendation 3.4). Any material 
breaches of the Anti-bribery and Corruption Policy are to

27

PRINCIPLE 4.  SAFEGUARD INTEGRIT Y 
OF CORPOR ATE REPORTS
The Board has an Audit Committee, which consists of 
only independent non-executive directors, has at least 
3 members and is chaired by an independent director as 
suggested in Recommendation 4.1. The Committee met 
twice during 2023, attended by all members. 

The Committee operates under a charter approved by 
the Board, a summary of which is available on the Neuren 
website. It is responsible for undertaking a broad review of, 
ensuring compliance with, and making recommendations in 
respect of, the Group’s internal financial controls and legal 
compliance obligations. In respect of financial reporting, it 
is also responsible for:

 – review of audit assessment of the adequacy and 

effectiveness of internal controls over the Company’s 
accounting and financial reporting systems, including 
controls over computerised systems;

 – review of the audit plans and recommendations of the 

external auditors;

 – evaluating the extent to which the planned scope of 
the audit can be relied upon to detect weaknesses in 
internal control, fraud and other illegal acts;
 – review of the results of audits, any changes in 

accounting practices or policies and subsequent effects 
on the financial statements and make recommendations 
to management where necessary and appropriate;
 – review of the performance and fees of the external 

auditor;

 – audit of legal compliance including trade practices, 

corporations law, occupational health and safety and 
environmental statutory compliance , and compliance 
with the Listing Rules of the ASX;

 – supervision of special investigations when requested 

by the Board

In undertaking these tasks the Audit Committee meets 
separately with management and external auditors where 
required. 

In accordance with Recommendation 4.2, the Board also, 
before it approves the entity’s financial statements for a 
financial period, receives a declaration in writing from the 
Chief Executive Officer and the Chief Financial Officer that 
the financial records of the company have been properly 
maintained and that the financial statements are in 
accordance with New Zealand Equivalents to International 
Financial Reporting Standards (NZ FRS) and present a 
true and fair view, in all material respects, of the Group’s 
financial position and performance and that this opinion 
is founded on a sound system of risk management and 
internal control that is operating effectively in all material 
respects with regard to business and financial reporting 
risks. The Board received those assurances for the annual 
financial statements on 29 February 2024.

Neuren Pharmaceuticals Limited Annual Report 2023CO R P O R AT E   G O V E R N A N C E

C O N T I N U E D

For other periodic corporate reports released to the 
market that are not audited or reviewed by an external 
auditor, processes are in place to ensure that the reports 
are materially accurate, balanced and provide investors 
with appropriate information to make informed investment 
decisions (Recommendation 4.3). Reports are prepared 
by the Chief Financial Officer and reviewed by the Chief 
Executive Officer, or are prepared by the Chief Executive 
Officer and reviewed by the Board. The Board receives a 
declaration in writing from the Chief Financial Officer and 
Chief Executive Officer regarding those reports.

PRINCIPLE 5.  MAKE TIMELY 
AND BAL ANCED DISCLOSURE
Neuren is required to comply with the continuous disclosure 
requirements as set out in the ASX Listing Rules, disclosing 
to the ASX any information that a reasonable person would 
expect to have a material effect on the price or value of 
Neuren’s securities, unless certain exemptions from the 
obligation to disclose apply.

In accordance with Recommendation 5.1, the Board has 
approved policies and procedures to ensure that it complies 
with its disclosure obligations and that disclosure is timely, 
factual, clear and objective. The Board has designated the 
company secretary as the person primarily responsible 
for implementing and monitoring those policies and 
procedures. A summary of the policies and procedures is 
available on the Neuren website. All information disclosed 
to the ASX is placed on the Neuren website after it has been 
published by the ASX, and the Board receives copies of all 
material market announcements promptly after they have 
been made (Recommendation 5.2).

All investor or analyst presentations with new information 
are released on the ASX Market Announcements Platform 
ahead of such presentations, in accordance with 
Recommendation 5.3.

PRINCIPLE 6.  RESPECT THE RIGHTS 
OF SECURIT Y HOLDERS
The Board strives to communicate effectively with 
shareholders, give them ready access to balanced and 
understandable information about the business and make 
it easy for them to participate in shareholder meetings.

In accordance with Recommendation 6.1, comprehensive 
information about the Company and its governance 
is provided via the website www.neurenpharma.com. 
This includes information about the Board and senior 
executives, as well as corporate governance policies. 
All announcements, presentations, financial information 
and meetings materials disclosed to the ASX are placed 
on the website, so that current and historical information 
can be accessed readily.

The Company’s investor relations program facilitates 
effective two-way communication with investors 
(Recommendation 6.2). The Chief Executive Officer interacts 
with institutional investors, private investors, analysts and 
media on an ad hoc basis, conducting meetings in person 
or by video/teleconference and responding personally 
to enquiries. 

The Board seeks practical and cost-effective ways to 
promote informed participation at shareholder meetings 
(Recommendation 6.3). This includes providing access to 
clear and comprehensive meeting materials and electronic 
proxy voting. The Annual Shareholders’ Meeting in 2023 
was conducted as a hybrid meeting, with participation 
both in-person and by electronic means.

All resolutions at the Company’s Annual 
Shareholders’ Meeting in 2023 were decided by a poll 
(Recommendation 6.4)

In accordance with Recommendation 6.5, shareholders are 
provided with and encouraged to use electronic methods to 
communicate with the Company and with the share registry.

PRINCIPLE 7.  RECOGNISE AND MANAGE RISK
The Board has established policies for the oversight and 
management of material business risks, a summary of which 
is available on the Neuren website. The Board does not have 
a separate committee to oversee risk, judging that the whole 
Board is better able to conduct that function efficiently 
and effectively, given the small size of the Board and the 
specialised nature of the business (Recommendation 7.1). 

In accordance with Recommendation 7.2, the Board 
reviews the Group’s risk management framework at least 
annually to satisfy itself that it continues to be sound. 
A review was conducted in 2023.

The size and complexity of the Group’s business is 
not sufficient to warrant an internal audit function 
(Recommendation 7.3). The risk management policy 
is designed to involve the entire organisation in risk 
management and to ensure that the effectiveness of 
the risk management and internal control processes 
are continually improved.

The Group does not have a material exposure to 
economic, environmental or social sustainability risks 
(Recommendation 7.4).

PRINCIPLE 8.  REMUNER ATE FAIRLY 
AND RESPONSIBLY
Neuren believes having highly skilled and motivated people 
will allow the organisation to best pursue its mission 
and achieve its goals for the benefit of shareholders and 
stakeholders more broadly. The ability to attract and retain 
the best people is critical to the Company’s future success. 

28

Neuren Pharmaceuticals Limited Annual Report 2023CO R P O R AT E   G O V E R N A N C E

C O N T I N U E D

The Board believes remuneration policies are a key part 
of ensuring this success.

The Board has a Remuneration Committee, which consists 
of only independent non-executive directors, has at least 
three members and is chaired by an independent director 
as suggested in Recommendation 8.1. The Committee met 
once during 2023. 

The Committee operates under a charter approved by 
the Board, a summary of which is available on the Neuren 
website. It is responsible for undertaking a broad review of, 
ensuring compliance with, and making recommendations 
in respect of, the Group’s remuneration policies. It is also 
responsible for:

 – setting and reviewing compensation policies and 

practices of the Company;

 – setting and reviewing all elements of remuneration of 
the directors and members of the executive team; and

 – setting and reviewing long term incentive plans for 

employees and/or directors.

In undertaking these tasks the Remuneration Committee 
meets separately with management where required.

The Group’s remuneration policies and practices 
are summarised below, in accordance with 
Recommendation 8.2.

The Remuneration Committee assesses the appropriateness 
of the nature and amount of remuneration of executive 
directors and senior executives on a regular basis by 
reference to relevant employment market conditions, with 
the overall objective of ensuring maximum shareholder 
benefit from the retention of a high quality executive 
team. To assist in achieving these objectives, the nature 
and amount of executive remuneration is linked to the 
Company’s performance. Remuneration consists of fixed 
cash remuneration, including superannuation contributions 
required by law, and equity-based remuneration. Fixed cash 
remuneration takes into account labour market conditions, 
as well as the scale and nature of the Group’s business. 
Equity-based remuneration is provided by participation in 
a share option plan and/or a loan funded share plan. These 
are designed to ensure that key executives are aligned 
with shareholders through an interest in the long-term 
growth and value of the Company. Senior executive service 
agreements generally include a requirement for 3 months’ 
notice of termination by the executive or the Group. There 
are no other termination payments. Termination for 
misconduct does not require notice or payment. The Group 
does not operate a short-term incentive plan, however 
discretionary bonuses may be approved to recognise 
exceptional achievement. Discretionary bonuses were 
approved in 2023, the amount of which took into account 
the value of the critical milestones achieved during the year 
in each of the three value drivers of the business.

29

Remuneration of non-executive directors comprises fixed 
cash fees only. The fees are determined by the Board 
within the aggregate limit for directors’ fees approved by 
shareholders. Non-executive directors on payroll receive 
retirement benefits as part of their fixed fee. All other non-
executive directors receive no retirement benefits.

Participants in equity based remuneration schemes 
are not permitted to enter into transactions which 
limit the economic risk of participating in the scheme 
(Recommendation 8.3).

PRINCIPLE 9.  ADDITIONAL 
RECOMMENDATIONS
Neuren is incorporated in New Zealand and ensures 
meetings of security holders are held at a reasonable place 
and time (Recommendation 9.2).

Since Neuren is incorporated in New Zealand and applies 
New Zealand financial reporting standards, its auditor 
is located in New Zealand. The Board has considered it 
impractical and an unnecessary expense for the auditor 
to travel to Australia to attend the annual general meeting 
in person, as suggested in Recommendation 9.3. The 
Company’s constitution enables the Board to convene 
virtual shareholder meetings, with participation by 
electronic means.

ENVIRONMENTAL AND SOCIAL IMPACT
Neuren’s small workforce of 24 people all work from home 
and no office or other facility is maintained. The incremental 
environmental impact is therefore negligible.

Pharmaceutical development for international markets 
necessarily requires some domestic and long-haul plane 
travel for some people. However, the improved technology 
and increased use of video meeting applications has 
enabled the frequency to be reduced. The necessity of any 
plane travel is always considered carefully before approval. 

Neuren’s work to develop treatments for serious 
neurodevelopmental disorders that have no approved 
medicines and have a devastating impact on families has 
a very high positive social impact, which is also highly 
motivating for Neuren’s workforce. Neuren works closely 
with the patient communities for each of the disorders and 
provides financial support to events organised by patient 
advocacy organisations.

Neuren aims to provide a positive and productive work 
environment for its workforce. Working from home provides 
people with high flexibility and enables optimum work/life 
balance. The small size of the team facilitates opportunities 
to experience and take responsibility for a broader range of 
activities. Staff turnover was zero in 2023.

1.  NATURE OF BUSINESS
Neuren Pharmaceuticals Limited (Neuren or the Company, 
and its subsidiaries, or the Group) is a publicly listed 
biopharmaceutical company developing drugs for 
neurological disorders.

The Company is a limited liability company incorporated 
in New Zealand. The address of its registered office in New 
Zealand is at the offices of Lowndes Jordan, Level 15 HSBC 
Tower, 188 Quay Street, Auckland 1141. Neuren ordinary 
shares are listed on the Australian Securities Exchange 
(ASX code: NEU).

These consolidated financial statements have been 
approved for issue by the Board of Directors on 
29 February 2024.

Material Uncertainties 
 – The Group’s licensing and research and development 
activities involve inherent risks. These risks include, 
among others: dependence on the sales made by 
licensees, the Group’s ability to retain key personnel; the 
Group’s ability to protect its intellectual property and 
prevent other companies from using the technology; 
part of the Group’s business is based on novel and yet to 
be proven technology; the Group’s ability to sufficiently 
complete the clinical trials process; and technological 
developments by the Group’s competitors could render 
its products obsolete.

 – The Group’s revenue from licence agreements includes 
quarterly royalty income contingent on the amount 
of ongoing sales, whilst other milestone payments 
are contingent on future sales and events and will be 
intermittent. The business plan therefore may require 
expenditure in excess of revenue and in the future the 
Group may need to raise further financing through other 
public or private equity financings, collaborations or 
other arrangements with corporate sources, or other 
sources of financing to fund operations. There can be 
no assurance that such additional financing, if available, 
can be obtained on terms reasonable to the Group.

2.   SUMMARY OF MATERIAL ACCOUNTING 

POLICIES

These general-purpose consolidated financial statements 
of the Group are for the year ended 31 December 2023 
and have been prepared in accordance with and comply 
with generally accepted accounting practice in New 
Zealand (GAAP), New Zealand equivalents to International 
Financial Reporting Standards (NZ IFRS) issued by the 
New Zealand Accounting Standards Board which comply 
with International Financial Reporting Standards, the 
requirements of the Financial Markets Conduct Act 2013, 
and other applicable Financial Reporting Standards 
as appropriate for profit- oriented entities that fall 
into Tier 1 as determined by the New Zealand External 
Reporting Board.

(a)  Basis of preparation

Entities Reporting
The consolidated financial statements incorporate the 
assets and liabilities of all subsidiaries of the Group as at 
31 December 2023 and the results of all subsidiaries for 
the year then ended. Neuren Pharmaceuticals Limited and 
its subsidiaries, which are designated as profit-oriented 
entities for financial reporting purposes, together are 
referred to in these financial statements as the Group.

Statutory Base
Neuren is registered under the New Zealand Companies 
Act 1993. Neuren is also registered as a foreign company 
under the Australian Corporations Act 2001.

Historical cost convention
These consolidated financial statements have been 
prepared under the historical cost convention as modified 
by certain policies below. Amounts are expressed in 
Australian Dollars and are rounded to the nearest thousand, 
except for earnings per share.

Critical accounting estimates
The preparation of financial statements requires the use 
of certain critical accounting estimates. It also requires the 
Group to exercise its judgement in the process of applying 
the Group’s accounting policies. Actual results may differ 
from those estimates. The areas involving a higher degree 
of judgement or complexity, or areas where assumptions 
and estimates are significant to the financial statements 
are disclosed in Note 19.

Going concern basis
The directors monitor the Group’s cash position and 
initiatives to ensure that adequate funding continues to 
be available for the Group to meet its business objectives. 
The Group recorded a profit after tax of $157.0 million 
for the year ending 31 December 2023 and had positive 
operating cash flows of $184.9 million for the year ended 
31 December 2023. The Group had cash of $17.1 million and 
short-term investments (term deposits) of $211.5 million at 
31 December 2023.

It is the considered view of the Directors that the Group 
will have access to adequate resources to meet its ongoing 
obligations for at least a period of 12 months from the 
date of signing these financial statements. On this basis, 
the Directors have assessed it is appropriate to adopt the 
going concern basis in preparing its consolidated financial 
statements. The consolidated financial statements do not 
include any adjustments that would result if the Group was 
unable to continue as a going concern.

Changes in accounting policies
There are no changes in accounting policies for the year 
ended 31 December 2023.

2.   SUMMARY OF MATERIAL ACCOUNTING 

POLICIES (CONTINUED)

Standards, interpretations and amendments to 
published standards that are not yet effective
At the date of authorisation of these consolidated 
financial statements, several new, but not yet effective, 
Standards and amendments to existing Standards, and 
Interpretations have been published by the IASB. None of 
these Standards or amendments to existing Standards have 
been adopted early by the Group. Management anticipates 
that all relevant pronouncements will be adopted for 
the first period beginning on or after the effective date of 
the pronouncement. New Standards, amendments and 
Interpretations not adopted in the current year have not 
been disclosed as they are not expected to have a material 
impact on the Group’s consolidated financial statements.

(b)  Principles of Consolidation

Subsidiaries
Subsidiaries are all entities (including structured entities) 
over which the group has control. The group controls 
an entity when the group 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.

Subsidiaries are fully consolidated from the date on which 
control is transferred to the group. They are deconsolidated 
from the date that control ceases.

All intra-group assets and liabilities, equity, income, 
expenses and cash flows relating to transactions 
between members of the Group are eliminated in full 
on consolidation. When necessary, amounts reported 
by subsidiaries have been adjusted to conform with the 
group’s accounting policies.

(c)  Foreign Currency Translation

(i) Functional and Presentation Currency
The functional currency of the Company and the 
presentation currency of the Group is Australian Dollars.

(ii) Transactions and Balances
Foreign currency transactions are translated into the 
functional currency using the exchange rates prevailing 
at the dates of the transactions. Foreign exchange 
gains and losses resulting from the settlement of such 
transactions and from the translation at year-end exchange 
rates of monetary assets and liabilities denominated in 
foreign currencies are recognised in the Statement of 
Comprehensive Income, except when deferred in equity as 
qualifying net investment hedges.

(iii) Foreign Operations
The results and financial position of foreign entities (none of 
which has the currency of a hyperinflationary economy) that 
have a functional currency different from the presentation 
currency are translated into the presentation currency as 
follows:

 – assets and liabilities for each Statement of Financial 
Position presented are translated at the closing rate 
at the date of that statement of financial position;

 – revenue and expenses for each Statement of 

Comprehensive Income are translated at average 
exchange rates; and

 – all resulting exchange differences are recognised as 

a separate component of equity.

Exchange differences arising from the translation of any 
net investment in foreign entities, and of borrowings and 
other currency instruments designated as hedges of such 
investments, are taken to a separate component of equity.

Goodwill and fair value adjustments arising on the 
acquisition of a foreign operation are treated as assets and 
liabilities of the foreign operation and translated at the 
closing rate.

(d)  Revenue
NZ IFRS 15 establishes a five-step model to account for 
revenue arising from contracts with customers and requires 
that revenue be recognised at an amount that reflects the 
consideration to which an entity expects to be entitled in 
exchange for transferring goods or services to a customer. 
The five-step process is as follows:

 – identify the contract(s) with a customer;
 – identify the performance obligations in the contract(s);
 – determine the transaction price;
 – allocate the transaction price to the performance 

obligations in the contract(s); and

 – recognise revenue when (or as) the performance 

obligations are satisfied.

Licence revenue
Licence revenues in connection with licensing of the Group’s 
intellectual property to customers are recognised as a right 
to use the entity’s intellectual property as it exists at the 
point in time at which the licence is granted. This is because 
the contracts for the licence of intellectual property 
are distinct and do not require, nor does the customer 
reasonably expect, that the Group will undertake further 
activities that significantly affect the intellectual property 
to which the customer has rights.

35

2.   SUMMARY OF MATERIAL ACCOUNTING 

POLICIES (CONTINUED)

Although the Group is entitled to sales-based royalties 
from sales of goods and services to third parties using 
the intellectual property transferred, these royalty 
arrangements do not of themselves indicate that the 
customer would reasonably expect the Group to undertake 
such activities, and no such activities are undertaken or 
contracted in practice. Accordingly, the promise to provide 
rights to the Group’s intellectual property is accounted for 
as a performance obligation satisfied at a point in time.

The following consideration is received in exchange for 
licences of intellectual property:

(i)    Up-front payments – These are fixed amounts and are 

recognised at the point in time when the Group transfers 
the intellectual property to the customer.

(ii)   Milestone payments – This is variable consideration that 

is contingent on the customer reaching certain clinical, 
regulatory or commercial targets in relation to the 
intellectual property licenced. Variable consideration 
is estimated using the most likely amount method, 
variable consideration is constrained such that amounts 
are only recognised when it is highly probable that 
a significant reversal in the amount of cumulative 
revenue recognised will not occur when the uncertainty 
associated with the variable consideration (that is, 
the customer meeting the conditions) is subsequently 
resolved. Milestone payments that are not in control 
of the Group, such as regulatory approvals, are not 
considered highly probable of being achieved until those 
approvals are received.

(iii)  Sales-based royalties – Licenses of intellectual property 
include royalties, which are variable consideration that 
are based on the sale of products that are produced 
using the intellectual property. The specific exception 
to the general requirements of estimating variable 
consideration for sales or usage-based royalties 
promised in a licence of intellectual property is applied. 
The exception requires such revenue to be recognised 
at the later of when (a) subsequent sales or usage occurs 
and (b) the performance obligation to which some or 
all of the sales-based or usage-based royalty has been 
allocated is satisfied (or partially satisfied).

Grants
Grant income is recognised in profit or loss within the 
Statement of Comprehensive Income over the periods in 
which the related costs for which the grants are intended to 
compensate are recognised as expenses and when there is 
reasonable assurance that the grant will be received and all 
attached conditions will be complied with.

Research and development tax incentives
Other income from the Australian government Research and 
Development tax incentive (RDTI) program is recognised 
when there is reasonable assurance that the tax incentive 
will be received and all attached conditions will be 
complied with. The research and development activities 
and expenditure are assessed to determine eligibility 
under the RDTI program. When Group revenue exceeds the 
threshold of aggregated turnover of $20 million or more, a 
non-refundable tax offset can be claimed. This is recognised 
as a reduction in current tax liability.

Interest income
Interest income is recognised as it is earned using the 
effective interest method.

(e)  Research and development
Research costs include direct and directly attributable 
overhead expenses for drug discovery, research and 
pre-clinical and clinical trials. Research costs are expensed 
as incurred.

(f)  Income tax
The income tax expense or benefit for the period is the tax 
payable on the period’s taxable income or loss using tax 
rates enacted or substantively enacted at the reporting 
date, adjusted by changes in deferred tax assets and 
liabilities attributable to temporary differences and unused 
tax losses.

Deferred tax assets and liabilities are recognised for 
temporary differences at the tax rates expected to apply 
when the assets are realised or liabilities are settled, based 
on those tax rates which are enacted or substantively 
enacted at the reporting date. The relevant tax rates are 
applied to the cumulative amounts of deductible and 
taxable temporary differences to measure the deferred 
tax asset or liability. An exception is made for certain 
temporary differences arising from the initial recognition of 
an asset or a liability in a transaction, other than a business 
combination, that at the time of the transaction did not 
affect either accounting profit or taxable profit or loss.

Deferred tax assets are recognised for deductible temporary 
differences and unused tax losses only if it is probable that 
the temporary differences will reverse in the foreseeable 
future and future taxable amounts will be available to utilise 
those temporary differences and losses.

Current and deferred tax balances attributable to amounts 
recognised directly in equity are also recognised directly 
in equity.

2.   SUMMARY OF MATERIAL ACCOUNTING 

POLICIES (CONTINUED)

(g)  Goods and services tax (GST)
The financial statements have been prepared so that all 
components are presented exclusive of GST. All items 
in the statement of financial position are presented net 
of GST, with the exception of receivables and payables, 
which include GST invoiced.

(h)  Cash and cash equivalents
Cash and cash equivalents comprises cash and demand 
deposits held with established financial institutions and 
highly liquid investments, which have maturities of three 
months or less that are readily convertible to known 
amounts of cash and which are subject to an insignificant 
risk of changes in value. Cash and cash equivalents are held 
to meet currently forecast short-term cash commitments.

(i)  Short-term investments
Short-term investments comprise short-term deposits, 
which have maturities of three months or less that are 
readily convertible to known amounts of cash and which 
are subject to an insignificant risk of changes in value. 
When the Group is holding more short-term deposits than 
are required to meet currently forecast short-term cash 
commitments, these are held as short-term investments.

(j)  Trade and other receivables
The Group makes use of a simplified approach in accounting 
for trade and other receivables and records the loss 
allowance as lifetime expected credit losses. These 
are the expected shortfalls in contractual cash flows, 
considering the potential for default at any point during 
the life of the financial instrument. In calculating, the 
Group assesses trade receivables on an individual basis, 
and uses its historical experience, external indicators and 
forward-looking information to calculate the expected 
credit losses.

(k)  Employee benefits

Wages and salaries, annual leave, long service leave and 
superannuation
Liabilities for wages and salaries, bonuses, annual leave, 
long service leave and superannuation expected to 
be settled within 12 months of the reporting date are 
recognised in accrued liabilities in respect of employees’ 
services up to the reporting date and are measured at 
the amounts expected to be paid when the liabilities are 
settled. Liabilities for non- accumulating personal leave are 
recognised when the leave is taken and measured at the 
rates paid or payable.

Contributions are made by the Group to employee 
superannuation funds and are charged as expenses when 
the obligation to pay them arises.

Share-based payments
Neuren operates a loan funded share plan and share option 
plan. Both plans are accounted for as share options and 
the loan is not recognised as an asset. The fair value of the 
services received in exchange for the grant of the options 
or shares is recognised as an expense with a corresponding 
increase in the share option reserve over the vesting period. 
The total amount to be expensed over the vesting period 
is determined by reference to the fair value of the options 
or shares at grant date. At each reporting date, except for 
options that are subject to a market condition for vesting, 
the Company revises its estimates of the number of options 
that are expected to vest. It recognises the impact of 
these revisions, if any, in the Statement of Comprehensive 
Income, and a corresponding adjustment to equity over the 
remaining vesting period.

When options are exercised, the proceeds received net of 
any directly attributable transaction costs are credited to 
share capital.

(l)  Share issue costs
Costs associated with the issue of new shares which 
are recognised in shareholders’ equity are treated as 
a reduction of the amount collected per share.

(m)  Financial instruments

Recognition and derecognition
Financial assets and financial liabilities are recognised when 
the Group becomes a party to the contractual provisions of 
the financial instrument.

Financial assets are derecognised when the contractual 
rights to the cash flows from the financial asset expire, or 
when the Group has transferred its rights to receive cash 
flows from the asset or has assumed an obligation to pay the 
received cash flows in full without material delay to a third 
party under a ‘pass-through’ arrangement; and either (a) the 
Group has transferred substantially all the risks and rewards 
of the asset, or (b) the Group has neither transferred nor 
retained substantially all the risks and rewards of the asset, 
but has transferred control of the asset.

When the Group has transferred its rights to receive cash 
flows from an asset or has entered into a pass-through 
arrangement, it evaluates if, and to what extent, it has 
retained the risks and rewards of ownership.

When it has neither transferred nor retained substantially 
all of the risks and rewards of the asset, nor transferred 
control of the asset, the Group continues to recognise 
the transferred asset to the extent of its continuing 
involvement. In that case, the Group also recognises an 
associated liability. The transferred asset and the associated 
liability are measured on a basis that reflects the rights and 
obligations that the Group has retained.

37

Neuren Pharmaceuticals Limited Annual Report 2023N O T E S   T O   T H E   C O N S O L I D AT E D   F I N A N C I A L   S TAT E M E N T S
C O N T I N U E D

2.   SUMMARY OF MATERIAL ACCOUNTING 

Subsequent measurement of financial assets

POLICIES (CONTINUED)

Continuing involvement that takes the form of a guarantee 
over the transferred asset is measured at the lower of the 
original carrying amount of the asset and the maximum 
amount of consideration that the Group could be required 
to repay.

A financial liability is derecognised when it is extinguished, 
i.e. the obligation is discharged, cancelled or expired.

Classification and initial measurement of financial assets
Except for those trade receivables that do not contain a 
significant financing component and are measured at the 
transaction price in accordance with NZ IFRS 15 ‘Revenue 
from contracts with customers’, all financial assets are 
initially measured at fair value adjusted for transaction 
costs (where applicable).

Financial assets, other than those designated and effective 
as hedging instruments, are classified into the following 
categories:

 – amortised cost
 – fair value through profit or loss (FVTPL)
 – fair value through other comprehensive income (FVOCI).

In the periods presented the company does not have any 
financial assets categorised as FVTPL or FVOCI.

The classification is determined by both:

 – the entity’s business model for managing the financial 

asset

 – the contractual cash flow characteristics of the financial 

asset.

All income and expenses relating to financial assets that 
are recognised in profit or loss are presented within finance 
cost or finance income, except for impairment of trade 
receivables which is presented within other expenses.

Financial assets at amortised cost
Financial assets are measured at amortised cost if 
the assets meet the following conditions (and are not 
designated as FVTPL):

 – they are held within a business model whose objective 
is to hold the financial assets and collect its contractual 
cash flows

 – the contractual terms of the financial assets give rise 

to cash flows that are solely payments of principal and 
interest on the principal amount outstanding.

After initial recognition, these are measured at amortised 
cost using the effective interest method.

Discounting is omitted where the effect of discounting 
is immaterial. The Group’s cash and cash equivalents, 
short- term investments and trade receivables fall into this 
category of financial instruments.

Classification and measurement of financial liabilities
The Group’s financial liabilities include trade and other 
payables and derivative financial liabilities. Financial 
liabilities are initially measured at fair value, and, where 
applicable, adjusted for transaction costs.

Subsequently, trade and other payables are measured at 
amortised cost using the effective interest method.

Derivative financial instruments are initially recognised 
at fair value on the date on which a derivative contract is 
entered into and subsequently remeasured at fair value. 
Derivatives are carried as financial assets when the fair 
value is positive and as financial liabilities when the fair 
value is negative. Gains or losses on derivative financial 
instruments are recognised in the profit or loss.

All revenue from licences of intellectual property is from the United States. The revenue from licences of intellectual property 
was earned by Neuren on the first commercial sale of DAYBUE by Acadia in the United States, and on signing the expanded 
worldwide licence agreement with Acadia.

4.  REVENUE (CONTINUED)
Neuren is eligible to receive quarterly royalty income, calculated as a percentage of net sales of DAYBUE in North America and 
is recognised in the period Acadia makes the sales of DAYBUE. Sales of DAYBUE commenced in April 2023. The royalty rate for 
annual sales of less than or equal to US$250 million is 10%. The royalty rate then increases to 12% for annual net sales greater 
than US$250 million but less than or equal to US$500 million.

 The adjustment to tax expense relates to the utilisation of a foreign income tax offset rather than previously unrecognised tax losses in relation to the prior 
year income tax return.
 The tax rate of the Group changed from the base rate of 25.0% to the full company tax rate of 30.0% effective 1 January 2023. Neuren is not a base rate entity 
for the year ended 31 December 2023 as its aggregated turnover for the year is greater than the aggregated turnover threshold of $50 million.

(a) 

 Of these gross tax losses, $62.5 million (2022: $62.6 million) relate to New Zealand tax losses, which are unlikely to be utilised unless future taxable income 
is generated in New Zealand. The movement in New Zealand gross tax losses is due to the New Zealand tax losses being translated at the closing foreign 
exchange rate at each reporting date. All previously unrecognised Australian tax losses have been utilised for the year ended 31 December 2023.

There are no franking credits or imputation credits available for use as at 31 December 2023 (2022: nil).

7.  EARNINGS PER SHARE
Basic earnings per share is calculated by dividing the profit for the year attributable to the equity holders of the company by 
the weighted average number of ordinary shares on issue during the year excluding shares held as treasury stock.

Diluted earnings per share is calculated by dividing the profit attributable to ordinary equity holders of the parent by the 
weighted average number of ordinary shares outstanding during the year plus the weighted average number of ordinary shares 
that would be issued on conversion of all the dilutive potential ordinary shares into ordinary shares.

Following the receipt of the first commercial sale milestone payment and the upfront payment for the expansion of the 
partnership with Acadia Pharmaceuticals for trofinetide to a worldwide exclusive licence, Neuren is holding more funds than 
are required to meet currently forecast short-term cash commitments. As a result, the Company has classified short-term 
deposits as short-term investments.

The Group has not recognised any amounts receivable in relation to the R&D tax incentive for the year ended 31 December 
2023, as a result of revenue exceeding the threshold of $20,000,000 in the financial year. As a result of exceeding this threshold, 
eligible R&D expenditure qualifies for a non-refundable tax offset and is recognised as a reduction in current tax liability.

In 2022 the R&D tax incentive receivable was determined based on a combination of eligible domestic and international 
expenditure of $1,988,057 at a rate of 43.5 cents tax incentive rebate per eligible R&D dollar spent. This amount was received in 
cash during the financial year.

The Group applies the simplified model of recognising lifetime expected credit losses for all trade receivables as these items do 
not have a significant financing component.

In measuring the expected credit losses, the trade receivables have been assessed on an individual basis due to the limited 
number of receivables.

The expected loss rates are based on the payment profile of the individual receivable including historical experience, external 
indicators and forward-looking information to calculate the expected credit losses.

Trade receivables are written off (i.e. de-recognised) when there is no reasonable expectation of recovery. Failure to make 
payments within 180 days from the invoice date and failure to engage with the Group on alternative payment arrangements 
amongst others are considered indicators of no reasonable expectation of recovery. No credit losses have been determined for 
the current year (2022: nil).

13.  SHARE C APITAL (CONTINUED)

Loan funded shares
The Company has a Loan Funded Share Plan to support the achievement of the Company’s business strategy by linking 
executive reward to improvements in the financial performance of the Company and aligning the interests of executives 
with shareholders. Under the Loan Funded Share Plan, loan funded shares may be offered to employees or consultants 
(“Participants”). The Company issues new ordinary shares, which are placed in a trust to hold the shares on behalf of the 
Participant. The trustee issues a limited-recourse, interest-free loan to the participant, which is equal to the number of shares 
multiplied by the issue price. A limited-recourse loan means that the repayment amount will be the lesser of the outstanding 
loan and the market value of the shares that are subject to the loan. The trustee continues to hold the shares on behalf of 
the Participant until all vesting conditions have been satisfied and the Participant chooses to settle the loan, at which point 
ownership of the shares is transferred from the trust to the Participant. Any dividends paid by the Company while the shares 
are held by the trust are applied as repayment of the loan at the after-tax value of the dividend. On request by the participant, 
the Company may dispose of, or buy back, vested shares and utilise the proceeds to settle the outstanding loan. The directors 
may apply vesting conditions to be satisfied before the shares can be transferred to the Participant. Before the loan can be 
given, the New Zealand Companies Act requires the Company to disclose to shareholders the provision of financial assistance 
to the Participant. The maximum loan term is 5 years.

All loan funded shares under the plan during the year ended 31 December 2023 are subject to the following vesting conditions:

i. 

ii. 

 40% of the Loan Funded Shares shall vest on acceptance by the US Food and Drug Administration of the filing of a New Drug 
Application for Trofinetide; and

 40% of the Loan Funded Shares shall vest when the Company determines to progress NNZ-2591 to a Phase 2b or Phase 3 
clinical trial following a positive Phase 2 clinical trial outcome, or executes a partnering transaction for NNZ-2591;

iii.   20% of the Loan Funded Shares shall vest when the Company executes a partnering transaction for trofinetide outside 
North America, or submits a Marketing Authorisation Application for trofinetide in the European Union, the United 
Kingdom, or Japan.

Each of these vesting conditions shall be tested separately from the other vesting conditions. The first vesting condition (i) was 
met in September 2022 and the third vesting condition (iii) was met in July 2023.

The estimated fair value of the shares has been determined using the Black-Scholes valuation model. The significant inputs 
into the model were the share price on date of valuation, the estimated future volatility of the share price, a dividend yield of 
0%, an expected life of 5 years, and an annual risk-free interest rate of 0.4%. The estimated future volatility of the share price 
was derived by analysing the historic volatility of the share price during the relevant period.

At 31 December 2023, the carrying value of all financial instruments approximated their fair value.

(b)  Risk management
The Group is subject to a number of financial risks which arise as a result of its activities.

Market risk
Market risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in 
market prices. Market risk comprises three types of risk: currency risk, interest rate risk and other price risk.

Currency risk
During the normal course of business the Group enters into contracts with overseas customers or suppliers or consultants that 
are denominated in foreign currency. As a result of these transactions there is exposure to fluctuations in foreign exchange 
rates. The Company also has a net investment in a foreign operation, whose net assets are exposed to foreign currency 
translation risk.

The principle currency risk faced by the business is the exchange rate between the Australian dollar and the US dollar. The 
Group holds cash denominated in US dollars and Australian dollars and has material revenue and expenditure in each of these 
currencies. Where possible, the Group matches foreign currency income and foreign currency expenditure as a natural hedge, 
holding foreign currency cash to facilitate this natural hedge. When foreign currency expenditure exceeds foreign currency 
revenue and foreign currency cash, the group purchases foreign currency to meet anticipated requirements under spot and 
forward contracts. The Group does not designate formal hedges.

18.  FINANCIAL INSTRUMENTS AND RISK MANAGEMENT (CONTINUED)
At 31 December 2023, there were three forward contracts to convert Australian dollars to US dollars outstanding. Adjustment 
of these financial instruments to fair value as measured at 31 December 2023 resulted in a loss of $2.2 million. This fair value 
measurement is categorised within Level 2 of the fair value hierarchy. A summary of the forward contracts outstanding at 
31 December 2023 is as follows:

Buy USD 
$'000

Sell AUD 
$'000

Weighted

exchange rate

Term

36,672 3 months or less

During the year, the US dollar fluctuated against the Australian dollar. A net foreign exchange gain of $2.4 million is included 
in results for the year ended 31 December 2023 (2022: $1.2 million), this includes a $1.9 million gain on the milestone revenue 
from Acadia (2022: $1.4 million gain).

The carrying amounts of US dollar denominated financial assets and liabilities are as follows:

An increase of 10% in the rate of the US dollar against the Australian dollar as at the reporting date would have decreased the 
consolidated profit after income tax by $18,418,196 (2022: $1,238,107). A decrease of 10% in the rate of the US dollar against the 
Australian dollar as at the reporting date would have increased the consolidated profit after income tax by $22,511,129 (2022: 
$1,514,242). An increase of 10% in the rate of the US dollar against the Australian dollar as at the reporting date would have 
decreased equity by $51,743 (2022: decrease of $12,419). A decrease of 10% in the rate of the US dollar against the Australian 
dollar as at the reporting date would have increased equity by $63,242 (2022: increase of $15,179).

Interest rate risk
The Group is exposed to changes in market interest rates as entities in the Group hold cash and cash equivalents and 
short-term investments.

The effective interest rates on financial assets are as follows:

Financial Assets

Cash and cash equivalents
    Australian dollar cash deposits
    Australian dollar interest rate
    US dollar cash deposits
    US dollar interest rate

2023

4.79%
168,688
4.67%

38,076
3.58%
2,104
–%

The Company and Group do not have any interest-bearing financial liabilities. Trade and other receivables and payables do not 
bear interest and are not interest rate sensitive.

A 5% change in average market interest rates would have changed reported profit after tax by approximately $537,400 (2022: 
$68,200). A 5% increase/decrease in the average market interest rates would have no impact on other components of equity.

18.  FINANCIAL INSTRUMENTS AND RISK MANAGEMENT (CONTINUED)

Credit risk
The Group incurs credit risk from transactions with financial institutions. The total credit risk on cash and cash equivalents 
and short-term investments, which have been recognised in the statement of financial position, is the carrying amount. The 
Company and its subsidiaries do not retain any collateral or security to support transactions with financial institutions. Cash 
and cash equivalents and short-term are held and transacted with National Australia Bank, Commonwealth Bank, Westpac, 
Western Union and Primis bank.

Liquidity risk
The Group’s financial liabilities, comprising trade and other payables and derivatives, are generally repayable within 
1 – 3 months. The maturity and availability of financial assets, comprising cash and cash equivalents, short-term investments 
and trade and other receivables, are monitored and managed to ensure financial liabilities can be repaid when due.

Capital management
The Group monitors capital including share capital, retained earnings and reserves and the cash and cash equivalents and 
short-term investments presented in the consolidated statement of financial position. The Group has no debt. The key 
objective of the Group when managing its capital is to safeguard its ability to continue as a going concern, so that the Group 
can sustain the future development of the research and development activities being performed by the Group.

19.  CRITIC AL ACCOUNTING ESTIMATES AND ASSUMPTIONS
The Group makes estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, 
seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing material 
adjustment to the carrying amounts of assets and liabilities within the next financial year are as discussed below.

The Group has assessed that all research and development expenditure to date does not meet the requirements for 
capitalisation as an intangible asset because it is not yet probable that the expected future economic benefits that are 
attributable to the asset will flow. The Group’s current assessment is that future expenditure will not meet that requirement 
prior to the approval of a New Drug Application by the US Food and Drug Administration.

The Group is subject to income taxes in Australia because it is domiciled in that country. There are transactions and 
calculations undertaken during the ordinary course of business for which the ultimate tax determination may be uncertain. 
Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will 
impact the current and deferred tax provisions in the period in which such determination is made.

The Group measures the fair value of loan funded shares and options to acquire ordinary shares with employees and 
consultants by reference to the fair value of the equity instruments at the date at which they are granted. The estimated fair 
value of the shares is determined using the Black-Scholes valuation model, taking into account the terms and conditions 
upon which the instruments were granted. Some judgements are made on the inputs into the valuation model, including 
the expected life and volatility.

To the Shareholders of Neuren Pharmaceuticals Limited 

Report on the Audit of the Consolidated Financial Statements 

Opinion 

We have audited the consolidated financial statements of Neuren Pharmaceuticals Limited (the “Company”) and its 
subsidiaries (the “Group”) on pages 30 to 50 which comprise the consolidated statement of financial position as at
31 December 2023, and the consolidated statement of comprehensive income, consolidated statement of changes in
equity and the consolidated statement of cash flows for the year then ended, and notes to the consolidated financial 
statements, including material accounting policy information.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the financial position 
of the Group as at 31 December 2023 and of its financial performance and cash flows for the year then ended in accordance 
with New Zealand equivalents to International Financial Reporting Standards (“NZ IFRS”) issued by the New Zealand 
Accounting Standards Board and International Financial Reporting Standards (“IFRS”).

Basis for Opinion 

We conducted our audit in accordance with International Standards on Auditing (New Zealand) (“ISAs (NZ)”) issued by the 
New Zealand Auditing and Assurance Standards Board. Our responsibilities under those standards are further described in 
the Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are independent 
of the Group in accordance with Professional and Ethical Standard 1 International Code of Ethics for Assurance Practitioners 
(including International Independence Standards) (New Zealand) issued by the New Zealand Auditing and Assurance 
Standards Board and the International Ethics Standards Board for Accountants’ International Code of Ethics for Professional 
Accountants (including International Independence Standards) (“IESBA Code”), and we have fulfilled our other ethical 
responsibilities in accordance with these requirements and the IESBA Code. We believe that the audit evidence we have 
obtained is sufficient and appropriate to provide a basis for our opinion. 

Other than in our capacity as auditor we have no relationship with, or interests in, the Group. 

Key Audit Matters 

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the 
consolidated financial statements of the current year. We have determined that there are no key audit matters to communicate 
in our report. 

Information Other than the Consolidated Financial Statements and Auditor’s Report thereon

The Directors are responsible for the other information. The other information comprises the information included in the annual 
report but does not include the financial statements and our auditor’s report thereon. The annual report is expected to be made 
available to us after the date of this auditor’s report. 

Our opinion on the consolidated financial statements does not cover the other information and we do not express any form of
audit opinion or assurance conclusion thereon. 

In connection with our audit of the consolidated financial statements, our responsibility is to read the other information and, in 
doing so, consider whether the other information is materially inconsistent with the consolidated financial statements, or our 
knowledge obtained in the audit, or otherwise appears to be materially misstated.

Member of Grant Thornton International Ltd. 

51

Neuren Pharmaceuticals Limited Annual Report 2023When we read the annual report, if we conclude that there is a material misstatement therein, we are required to communicate 
the matter to those charged with governance. 

Directors’ responsibilities for the Consolidated Financial Statements 

The Directors are responsible on behalf of the Company for the preparation and fair presentation of the consolidated financial 
statements in accordance with NZ IFRS, and for such internal control as the Directors determine is necessary to enable the 
preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error. 

In preparing the consolidated financial statements, the directors are responsible on behalf of the Company for assessing the 
Group’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going 
concern basis of accounting unless the directors either intend to liquidate the Group or to cease operations, or have no 
realistic alternative but to do so. 

Auditor’s responsibilities for the Audit of the Consolidated Financial Statements 

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free 
from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. 
Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with ISAs 
(NZ) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered 
material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users 
taken on the basis of these consolidated financial statements. 

A further description of the auditor’s responsibilities for the audit of the consolidated financial statements is located on the 
External Reporting Board’s website at: https://www.xrb.govt.nz/assurance-standards/auditors-responsibilities/audit-report-1/ 

Restriction on use of our report 

This report is made solely to the Company’s shareholders, as a body. Our audit work has been undertaken so that we might 
state to the Company’s shareholders, as a body, those matters which we are required to state to them in an auditor’s report 
and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other 
than the Company and the Company’s shareholders, as a body, for our audit work, for this report or for the opinion we have 
formed.

AUSTR ALIAN STOCK EXCHANGE DISCLOSURES
Neuren Pharmaceuticals Limited is incorporated in New Zealand under the Companies Act 1993.

The Company is not subject to Chapter 6, 6A, 6B and 6C of the Corporations Act, Australia, dealing with the acquisition of

Limitations on the acquisition of shares imposed under New Zealand law are as follows:

(a)   In general, securities in the Company are freely transferable and the only significant restrictions or limitations in relation to 

the acquisition of securities are those imposed by New Zealand laws relating to takeovers and overseas investment.

in certain permitted ways. These include a full takeover offer in accordance with the Takeovers Code, a partial takeover 
in accordance with the Takeovers Code, an acquisition approved by an ordinary resolution, an allotment approved by an 
ordinary resolution, a creeping acquisition (in certain circumstances), or compulsory acquisition of a shareholder holding 
90% or more of the shares.

investments in New Zealand by overseas interest. In general terms, the consent of the New Zealand Overseas Investment 
Office may be required where an ‘overseas person’ acquires shares in the Company that amount to 25 % or more of the 
shares issued by the Company, or if the overseas person already holds 25% or more, the acquisition increases that holding.
