Chairman’s Statement 
The 2024 financial year was a pivotal period of transition, validation, and progress for Hemogenyx 
Pharmaceuticals plc. In an industry climate marked by capital constraints and macroeconomic 
uncertainty, we advanced boldly into clinical-stage development, made substantial progress across all our 
programs, and built momentum that has carried us strongly into 2025. 
Our mission—to deliver innovative therapies to patients suffering from life-threatening hematologic 
conditions—remains at the heart of all we do. This past year has demonstrated our scientific discipline, 
operational resilience, and unwavering commitment to patients, partners, and shareholders. 
HG-CT-1 (formerly HEMO-CAR-T) 
Our lead clinical asset, HG-CT-1, is a proprietary CAR-T cell therapy designed to treat relapsed or 
refractory acute myeloid leukemia (R/R AML). In June 2023, our IND submission to the U.S. Food and 
Drug Administration (FDA) was placed on clinical hold due to third-party vector impurities. This was 
addressed swiftly and transparently through a complete investigation and corrective actions. 
In January 2024, the FDA lifted the clinical hold, allowing us to resume clinical development. Thereafter, 
we received IRB approval from MD Anderson Cancer Center, cleared all institutional onboarding, and 
prepared for patient enrolment. 
In February 2025, we dosed our first patient in the Phase I trial of HG-CT-1, marking a historic milestone 
for the Company. By March, we announced that the treatment had been well tolerated, with no adverse 
effects observed, successfully passing the initial safety assessment. Early signals of efficacy were 
encouraging, and monitoring continues in accordance with protocol. 
Also in March, the second patient was recruited, and manufacturing of HG-CT-1 was initiated. In April 
2025, we filed our first FDA-mandated Annual IND Report, documenting our progress and setting a 
roadmap for continued enrolment in the year ahead. 
In parallel, we expanded the clinical program through a strategic partnership with Prevail InfoWorks and 
Prevail Partners. This collaboration supports pediatric development and additional clinical sites in the 
U.S., further accelerating the program’s scalability and reach. 
CBR Platform 
Hemogenyx’s Chimeric Bait Receptor (CBR) technology has continued to evolve as both a highly 
promising anti-cancer and antiviral immunotherapy platform. In 2024, we made substantial strides across 
multiple fronts: 
- 
We demonstrated improved efficiency in lentiviral transduction for CBR-expressing cells.  
- 
Developed an intranasal mRNA-based delivery route potentially enabling mucosal immunity—a 
key advance for respiratory infections. 
- 
Progressed IND-enabling studies, including scale-up and formulation work, while identifying 
central nervous system related indications.

The CBR platform also gained attention at major conferences, including the Macrophage-directed 
Therapies Summit and the CBD Science & Technology Symposium, where Hemogenyx Pharmaceuticals 
presented its preclinical progress. 
CDX Antibody Program 
We continued IND-enabling work for our CDX bispecific antibody for the treatment of R/R AML as well 
as conditioning in transplant settings. In early 2024, a new clone of the antibody was developed with 
improved affinity and manufacturability. This platform remains a priority for future partnering and 
development opportunities. 
Strategic Manufacturing Partnership 
In December 2024, we announced a collaboration with Kure.ai to co-develop an ultrafast CAR-T 
manufacturing platform tailored to HG-CT-1. This partnership has the potential to dramatically reduce 
production times, improve scalability, and extend our technology to broader hematologic indications, 
including KMT2A-rearranged Acute Lymphoblastic Leukemia. 
Financing and Investor Confidence 
Despite one of the most challenging biotech funding climates in recent memory, we successfully raised 
over £3.9 million (before expenses) in 2024 and completed three further equity financings in Q1 2025 
totalling £1.33 million (before expenses). Including, in March 2025, when we welcomed a new 
institutional investor contributing £709,200 to support the HG-CT-1 trial. This continued access to capital 
reflects growing investor confidence in our science and strategy. 
The milestones achieved by the Company over the last year underscore the exceptional progress we have 
made—advancing multiple complex programs with a level of capital efficiency that is rarely achieved in 
our industry. This track record is a testament to the strength of our team, our focus, and our ability to 
deliver meaningful results with disciplined use of resources. 
Corporate Developments 
In January 2025, we appointed Westend Corporate LLP as our new Company Secretary and relocated 
our registered office to 6 Heddon Street, London. 
We also maintained transparency with regulators and stakeholders by submitting our FDA IND annual 
report and keeping the market updated through regular RNS announcements. 
Looking Forward 
We enter the second quarter of 2025 with optimism and focus. The successful first-in-human 
administration of HG-CT-1, promising early results, and the recruitment of the second patient firmly 
establish Hemogenyx as a clinical-stage company with real-world momentum. 
We are deeply grateful to our shareholders for their continued support and belief in the Company, 
especially during a period of transformation. We strive every day to create long-term value for them and 
for all stakeholders. 
Finally, I would like to thank our extraordinary team of scientists and advisors for their perseverance, 
vision, and dedication. Hemogenyx is positioned not only to progress but to lead in transforming the 
treatment of life-threatening blood diseases.

Board of Directors and Senior Management 
Professor Sir Marc Feldmann – Non-Executive Director & Chairman – appointed 9 April 2018 
 
Professor Sir Marc Feldmann is a pre-eminent medically trained immunologist at the University of 
Oxford where he was Head of the Kennedy Institute of Rheumatology until 2014 and now Emeritus 
Professor, and a Visiting Professor at Rockefeller University, New York. He trained in medicine at 
Melbourne University and then earned a Ph.D. in Immunology at the Walter & Eliza Hall Institute with 
Sir Gus Nossal, before working in London at the Imperial Cancer Research Fund. Sir Marc's main 
research interests are immunoregulation, understanding mechanisms of autoimmunity and the role of 
cytokines in disease, and working out how to fill unmet medical needs. 
 
His work in London led to the generation of a new hypothesis for the mechanism of autoimmunity, linking 
upregulated antigen presentation and cytokine expression. Testing this hypothesis led to the discovery, 
with colleague Sir Ravinder Maini, of the pivotal role of TNFα (Tumour Necrosis Factor alpha) in the 
pathogenesis of rheumatoid arthritis. This major discovery has revolutionised therapy not only of 
rheumatoid arthritis but other chronic inflammatory diseases (e.g. inflammatory bowel disease, psoriasis, 
and ankylosing spondylitis), and helped change the perception of monoclonal antibodies from niche 
products to mainstream therapeutics. Anti-TNF therapeutics are the current leading drug class with 2022 
sales exceeding US$42 billion. 
 
This has led to much scientific recognition, for example election to the Royal Society and Academy of 
Medical Sciences in London, the National Academy of Sciences USA and the Australian Academy of 
Science, and multiple major International prizes including the Crafoord Prize of the Royal Swedish 
Academy of Sciences, the Albert Lasker Clinical Research Award (NY), the Ernst Schering Prize, the 
Paul Janssen Award for Biomedical Research, the Canada-Gairdner Award, and more recently the Tang 
prize. He was also the first recipient in biology or medicine of the EU/European Patent Office Inventor 
of the Year Award in the Lifetime Achievement category. In addition, Sir Marc has advised more than 
20 of the largest pharmaceutical and biotech companies in the world and has mentored some of the most 
successful scientists, many of whom have become senior figures in the commercial pharmaceutical world. 
Sir Marc was knighted in the 2010 Queen's Birthday Honours, and was honoured in Australia with the 
knighthood equivalent, the Companion of the Order of Australia. 
 
Sir Marc has been at the forefront of promoting effective scientific-medical-pharmaceutical interactions. 
He has built up a huge network of friends and collaborators who meet regularly in Oxford and who will 
help Hemogenyx Pharmaceuticals to grow.

led a team of scientists at Advanced Cell Technologies, Inc. and was most recently on the faculty of Weill 
Cornell Medical College. While at Cornell, Dr Sandler made the significant discovery that the cells that 
give rise to blood stem cells during mammalian development continue to exist after birth, and he 
developed the method of isolation of these cells from humans. As a result of this important work, Dr 
Sandler was awarded the inaugural Daedalus Fund Award for Innovation at Cornell. He went on to found 
Hemogenyx Pharmaceuticals in order to further pursue this significant scientific discovery and his 
dedication to the translation of science into clinical practice. 
 
Dr Sandler has published numerous peer-reviewed papers and has received a number of awards and 
fellowships for his scientific research. Dr Sandler received his PhD from the University of British 
Columbia. He is a member of the International Society for Stem Cell Research. 
 
Alexis Sandler – Non-Executive Director – appointed 4 October 2017 
 
Alexis M. Sandler is the co-founder of Hemogenyx Pharmaceuticals, for which she has served as the 
Chief Operating Officer. Ms Sandler is an attorney specialising in intellectual property, with over 20 
years of experience representing a range companies and institutions.

Peter Redmond – Non-Executive Director – appointed 29 July 2015 
 
Peter Redmond is a corporate financier with over 40 years’ experience in corporate finance and venture 
capital. He has acted on and assisted a wide range of companies to attain a listing over many years on the 
former Unlisted Securities Market, the Main Market of the London Stock Exchange and AIM, whether 
by IPO or in many cases via reverse takeovers, across a wide range of sectors, ranging from 
pharmaceuticals, through technology, financial services and natural resources. In recent years has done 
so as a director and investor in the companies concerned. 
 
He was a founder director of a number of investment companies listed on the Standard List of the Stock 
Exchange, all of which went on to complete significant reverse takeovers resulting in admission as active 
businesses on AIM or back onto the Standard List. In particular, he was a founder director of Silver 
Falcon plc, the Company into which Hemogenyx Pharmaceuticals reversed, and he took a leading role in 
negotiating and effecting the reverse takeover. He undertook the same role in the rescue, reconstruction 
and refinancing of many AIM-quoted companies that had previously run into difficulties and took a 
significant active part in fundraising for the above companies – in particular Standard-listed GEM 
Resources plc, of which he remains a director.

Directors’ Strategic Report for the year ended 31 December 2023 
The Directors present their Strategic Report of Hemogenyx Pharmaceuticals plc for the year ended 31 
December 2024. 
 
Introduction 
This Strategic Report comprises several sections, namely: the Group’s objectives, the Group’s strategy 
and business model, a review of the Group’s business using key performance indicators, and the principal 
risks and uncertainties facing the business.  
 
The disclosures under s172 of the Companies Act 2006 are included in the Governance Report on page 
26. 
 
Objectives 
The Group’s objective is to develop breakthrough therapies for the treatment of blood and autoimmune 
diseases, rare cancers and of certain viral infections. 
 
Strategy and Business Model 
 
The Group’s long-term strategy is to create a suite of products to address current problems associated 
with the treatment of blood disorders such as leukemia-type cancers and autoimmune diseases, with the 
treatment of viral infections and certain non-blood cancer conditions, and advanced methods of 
conditioning of blood stem-cell transplants. The latter represents an important part of the solution to 
treating blood-related diseases, with the opportunity to improve outcomes through reduced blood stem 
cell transplant rejection and relapse, and if successful potentially provides long-term cures for these 
diseases. 
 
The Group’s business model aims to advance its therapies through clinical proof-of-concept, taking them 
towards a final stage of development. This is intended to be achieved either through the Company itself 
taking the product into and through clinical trials or by the licensing of one or more of its therapies to 
partners in return for potential upfront payments, research funding support, success milestone and royalty 
payments. 
 
Operational Review and Outlook 
 
The operational review and outlook are set out in the Chairman’s Statement on page 3. 
 
Financial Review 
 
The Group incurred a loss for the year to 31 December 2024 of £5,625,478 (31 December 2023: 
£6,696,493 loss). 
 
In the year to 31 December 2024 the loss mainly arose from operational expenses pursuing the Group’s 
objectives listed above as well as salaries, consulting and professional fees, and general administration 
expenses. These expenses have been met from the proceeds of equity placings that were undertaken 
during the period.

Cash flow and cash position 
 
Cash used in operations totalled £3,516,813 (31 December 2023: £6,105,570). 
 
As at 31 December 2024, the Group had a cash balance of £159,265 (31 December 2023 - £1,247,601). 
 
Key Performance Indicators (“KPIs”) 
 
The Directors have identified the KPIs below that they feel are the most vital measurements for the Group 
to monitor given its current stage of development. KPIs are monitored on an annual basis to ensure that 
they remain the most important and relevant measure of performance and progress. 
 
Cash management 
 
In the year the Company undertook several fundraises in furtherance of its research and development 
strategy, raising a total of £3,925,000 (before expenses). As of 31 December 2024 the cash position was 
£159,265 (31 December 2023: £1,247,601). 
 
The Group carefully plans expenditure with rolling cash flow forecasts and tight financial control. The 
Group takes a collaborative cost sharing approach with business partners and avoids long-term 
commitments as far as possible. 
 
As detailed in the Future Developments and Events Subsequent to the Year End note on page 21, in 
January 2025 the Company successfully raised £340,000 (before expenses) through the issue of 100,000 
new ordinary shares at a price of 340p per share. In February 2025 the Company raised £285,000 through 
the issue of convertible loan notes, which converted into 95,000 ordinary shares on 13 March 2025. 
 
Additionally, on the 11 March 2025 the Company announced it had issued 394,000 new ordinary shares 
raising £709,200 (before expenses).  
 
Intellectual property 
 
The Group is focused on developing new drugs and cell therapy products for blood and autoimmune 
diseases, HSC/BM transplantation, rare cancers and certain viral infections. The Group, or its licensors, 
has applied for patents to protect its proprietary technology and future products, which are in varying 
stages of development. 
 
The success of the Group will depend largely on the Group’s ability to implement successful drug 
development programmes, obtain the required regulatory approvals (in various territories), protect and 
exploit its own intellectual property and know-how and the intellectual property and know-how licensed 
to it, and to generate a cash flow in accordance with the strategy of the Group. Intellectual property is 
protected by the Group through taking a pro-active approach to filing patents over its products and 
technologies, as well as the diligent maintenance and protection of such patents and licences. 
 
The Group patent portfolio currently includes:  
 
CDX bi-specific antibodies (“CDX”) 
 
The patent application relating to CDX bi-specific antibodies was filed by Hemogenyx Pharmaceuticals 
LLC in the USA on 4 April 2016 ("CDX Patent") and awarded as Patent Number US 11,021,536 B2 on 
1 June 2021. The invention summarised in the patent application is a method of eliminating hematopoietic 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
10 
stem cells/hematopoietic progenitors ("HSC"/"HP") in a patient using bi-specific antibodies specifically 
binding to a protein predominantly expressed on the surface of HSC/HP and to a protein uniquely 
expressed on a surface of immune cells. The bound bi-specific antibodies redirect immune cells to 
eliminate HSC/HP. The invention relates to the required conditioning of a patient prior to a BM/HSC 
transplant. In this respect, the invention serves two main purposes: 
 
§ it provides adequate immunosuppression of the patient and clears sufficient niche space in the 
bone marrow for the transplant of HSC. This allows transplanted cells to engraft in the recipient; 
and 
§ it could potentially help to eradicate the source of malignancy. 
 
On 4 April 2017, an international PCT (Patent Cooperation Treaty) application was filed by Hemogenyx 
Pharmaceuticals which includes additional claims that extend the CDX Patent set out in the provisional 
patent application. These claims protect specific sequences of several high-quality clones discovered and 
validated by the Group. The claim extension transforms the original "method" provisional patent 
application into a "composition of matter" PCT application. A patent was granted in China in July 2022 
covering both transplant conditioning and AML treatment applications. An additional composition of 
matter patent application titled Bispecific Anti-FLT3/CD3 Antibodies and Methods of Use (covering novel 
sequences of the antibodies discovered and validated by the Company in collaboration with Eli Lilly & 
Company) was filed following completion of the Lilly collaboration agreement and was published by the 
World Intellectual Property Organization on 23 February 2023 as publication number WO/2023/023489. 
 
Furthermore, on the 2 February 2024 the United States Patent and Trademark Office granted a patent to 
the Company entitled Method of Eliminating Hematopoietic Stem Cells/Hematopoietic Progenitors 
(HSC/HP) in s Patient Using Bi-specific Antibodies. The original patent application is issued as U.S. 
Patent No. 11,945,866 on 2 April 2024. 
 
Monoclonal antibodies 
 
In July 2019 the Group filed a composition of matter patent application entitled Monoclonal Antibodies 
to Human FLT3/FLK2 Receptor Protein in relation to newly-discovered monoclonal antibodies against 
a target protein expressed on the surface of hematopoietic stem cells/hematopoietic progenitors and a 
number of leukemias, such as acute myeloid leukemia (“AML”). The patent was granted on 31 August 
2021 as Patent Number US 11,104,738. This patent covers composition of matter (sequences) of 
monoclonal antibodies to the human FLT3/FLK2 receptor protein that is found on the surface of acute 
myeloid leukaemia cells, hematopoietic (blood-forming) stem cells and progenitors (“HSC/HP”), and 
dendritic cells. It also covers a method of application of the Group’s bi-specific CDX antibodies for 
conditioning patients for bone marrow transplantation. 
 
HG-CT-1  
 
A PCT patent application titled Anti-FLT3 Antibodies, CARs, CAR T Cells and Methods of Use was 
published by the World Intellectual Property Organization on 23 February 2023 under number 
WO/2023/023491, detailing the Company’s Chimeric Antigen Receptor sequences including anti-FLT3 
antibodies. 
 
Hu-PHEC cell therapy 
 
The patent relating to Hu-PHEC was filed by Cornell University in several jurisdictions on 13 November 
2014. The patent was approved and issued in the United States of America on 25 February 2020 and 
published by the European Patent Office on 13 May 2020. The invention summarises a method of 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
11 
isolation and identification of post-natal hemogenic endothelial cells, as well as the provision of 
substantially purified populations of post-natal hemogenic endothelial cells, compositions of post-natal 
endothelial cells and methods to utilise post-natal hemogenic endothelial cells to regenerate the 
hematopoietic system in a patient. 
 
Advanced Hematopoietic Chimeras 
 
The provisional patent application relating to the Group’s proprietary humanised mouse model, the 
Advanced Hematopoietic Chimera (“AHC”), is an application filed by Dr Sandler and Dr Rita Simone in 
the USA on 20 February 2018. The invention summarised in the patent application is mice whose 
hematopoietic system is at least 40% humanised and methods for preparing the same. The patent was 
assigned to the Group’s subsidiary Immugenyx LLC on 24 May 2018. In June 2019 the Group announced 
that Immugenyx LLC has further refined its work to develop the Advanced peripheral blood 
Hematopoietic Chimera ("ApbHC") as a research and development tool. The major advantage of the 
ApbHC compared to other humanised mouse models known to the Group is the absence of Graft versus 
Host Disease, a disease that complicates and often renders impossible the efficient use of peripheral blood 
mononuclear cells in transplanted mice. The ApbHC can potentially be used for testing multi-specific 
antibodies, including its own bi-specific CDX antibody, as well as for the development and testing of 
new cell therapies involving immune cell programming such as CAR-T. ApbHC can also potentially be 
used for the modelling of autoimmune diseases, such as Systemic Lupus Erythematosus (aka Lupus), 
with a goal of developing fundamentally new treatments for those diseases. 
 
Chimeric Bait Receptor (“CBR”) 
 
In March 2022, the Company filed a seminal provisional patent application protecting its rights to the 
intellectual property covering its CBR platform technology, a new paradigm for treating viral infections 
from which constructs targeting viral pathogens and potentially malignancies may be derived and for 
certain cancer and neurological conditions On 7 September 2023 the Company filed patent application 
number WO2023168292 Chimeric Bait Receptors and Uses Thereof with the World Intellectual Property 
Organization. At the time of reporting, it remains to be reviewed and approved by national patent 
authorities. 
 
Product development 
 
The Group develops therapies for the treatment of AML, for the treatment of a range of viral conditions 
and certain rare cancers and conditions as well as for the improvement of bone marrow and blood stem 
cell transplant procedures.  
HG-CT-1 is a therapy for the treatment of AML in which a patient’s own T-cells, a type of immune cell, 
are modified to recognise and kill the patient’s cancer cells. The procedure involves: isolating T-cells 
from the patient; modifying the isolated T-cells in a laboratory using a CAR gene construct (which allows 
the cells to recognise the patient’s cancer); amplifying (growing to large numbers) the newly modified 
cells; and re-introducing the cells back into the patient. 
CBR is a broad and versatile range of potential treatments based on the methodology of programming 
immune cells using a novel type of modifiable synthetic receptor to destroy viral pathogens. This 
approach can also potentially be used to programme immune cells to destroy malignant cells causing 
certain types of cancer and potentially also some neurological conditions.

CDX aims to treat AML as well as to replace the need for existing methods of preparation of patients for 
transplantation, such as chemotherapy and radiation treatments, and at the same time address the problem 
of finding matching stem cell donors whilst reducing the risk of blood stem cell rejection after 
transplantation. 
 
The Group’s lead product, HG-CT-1, is at the stage of conducting clinical trials. Its other key products, 
CDX antibodies, the CBR platform, and CBR, are currently in preclinical development. In addition, the 
Group’s advanced hematopoietic chimeric (“AHC”) mice have been the subject of collaborations with 
other pharmaceutical companies to evaluate AHCs’ effectiveness as platforms for disease modelling and 
drug discovery and are being used by the Company currently for its own product development. 
 
The Directors monitor product development through pre-clinical results. The CDX and CAR-T products 
have been successfully evaluated in the Group’s proprietary humanised mouse model, achieving proof of 
concept. Furthermore, we have achieved notable demonstrations of both CDX’s and HG-CT-1’s activity 
versus AML cells in vitro and in vivo. If successful, the Company may be able to use the CDX and/or 
CAR-T products to eliminate relapsed or refractory acute myeloid leukaemia (“R/R AML”) in patients 
who qualify for bone marrow transplantation. HG-CT-1 has already entered clinical trials. The Company 
is also investigating the possibility of using its CDX antibodies in combination with other treatments for 
AML to increase their effectiveness. 
 
A CBR construct designed to target SARS-CoV-2 has been tested in vitro, and in vivo tests against live 
replicating viruses are ongoing, as is work on CBR for use against certain cancers such as Non-Hodgkin 
Lymphoma (“NHL”) certain solid tumours and neurological conditions.

Corporate Responsibility 
 
We have defined the scope of our Group’s responsible business practices as falling within the following 
key focus areas: 
§ Health and Safety – ensuring the safety and well-being of our staff 
§ Environment – managing our environmental impact areas of waste, energy and water 
§ Employees – supporting our people to develop and flourish within the business 
§ Community – positive interaction with the communities in which we operate 
§ Ethical Standards – operating to the highest ethical standards 
 
We remain committed to ensuring these activities become embedded in how we operate and contribute 
towards the success of our business. This includes not only identifying and managing business risk but 
exploring opportunities to add value to the business. 
 
Greenhouse Gas Emissions 
 
Given the nature of its activities, there is limited scope for the Group to have a major impact on 
environmental matters. Nevertheless, the Directors are mindful of their responsibilities in this regard and 
strive to seek opportunities where improvements may be made. 
 
Climate-related Financial Disclosures 
 
The Financial Stability Board’s Task Force on Climate-related Financial Disclosures (TCFD) 
recommendations serve as a global foundation for effective reporting on the operational and financial 
implications of the interrelationship between climate change and business, and set out recommended 
disclosures structured under four core elements: 
 
• Governance – The organisation’s governance around climate-related risks and opportunities  
• Strategy – The actual and potential impacts of climate-related risks and opportunities for an 
organisation’s businesses, strategy, and financial planning  
• Risk Management – The processes used by the organisation to identify, assess, and manage 
climate-related risks; and  
• Metrics and Targets – The metrics and targets used to assess and manage relevant climate-related 
risks and opportunities.

These are supported by recommended disclosures that build on the framework with information intended 
to help investors and others understand how reporting companies assess climate-related risks and 
opportunities.

Governance 
• 
Board’s oversight of 
climate-related risks and 
opportunities 
• 
Management’s role in 
assessing and managing 
climate-related risks and 
opportunities 
As a development stage biopharmaceutical 
business, the Group’s operations are at a 
relatively small scale and so therefore is its 
environmental 
impact. 
Nevertheless, 
the 
Board recognises its responsibility to protect 
the environment (particularly as the business 
scales up). 
The Board has oversight of climate-related 
matters 
(which 
include 
risks 
and 
opportunities). The board is supported by the 
Audit Committee, which is responsible for 
keeping under review the adequacy and 
effectiveness of the Group’s internal control 
and risk management systems, which consider 
climate-related risks. 
Strategy 
• 
Climate-related risks and 
opportunities identification 
• 
Climate-related risks and 
opportunities impacts 
• 
Resilience of the 
organisation’s strategy 
Hemogenyx Pharmaceuticals is committed to 
a net zero and healthier planet, and this is part 
of the Group’s strategic long-term priorities. 
The Board is committed to conserving natural 
resources and striving for environmental 
sustainability, by ensuring that its facilities 
(and the facilities of academic and contracted 
collaborators) are operated to optimise energy 
usage; minimising waste production; and 
protecting nature and people. 
As Hemogenyx Pharmaceuticals enters the 
next stage of its development, clinical trials, 
ESG will be at the heart of the Board and 
management’s vision and strategy to enable 
climate-related risks and opportunities to be 
identified and suitably mitigated/actioned. 
The information collected will allow the Board 
to challenge the Group’s strategy to ensure it is 
as resilient as possible. 
In the short-term, clinical trials are not 
expected to have any impact on the Company’s 
environmental impact as research will remain 
small and within the same facilities it currently 
operates from. However, this will be 
continually monitored.  
Risk Management 
• 
Identifying and assessing 
climate-related risks 
Given the small scale of its current operations, 
Hemogenyx Pharmaceuticals has the ability to 
embed 
climate-related 
risk 
management 
systems into its overall internal control

Hemogenyx Pharmaceuticals Summary 
• 
Managing climate-related 
risks 
• 
Integration into overall risk 
management 
systems from an early stage of its journey, thus 
almost eliminating the occurrence of transition 
risk. 
As operations scale up in the coming years, the 
identification, 
assessment 
and 
effective 
management of climate-related risks and 
opportunities will be actively discussed during 
Board and management meetings. 
Metrics and Targets 
• 
Climate-related metrics  
• 
Scope 1, Scope 2, and 
Scope 3 emissions.  
• 
Climate-related targets  
 
As the Group’s operations scale up, it will 
continue to monitor its energy use. The Group 
will seek to collect, structure, and effectively 
disclose related performance data for the 
material 
climate-related 
risks 
and 
opportunities identified where relevant. 
The Board will also look to adopt SASB 
recommended disclosures in the next 2-3 
years. 
The Group already minimises business travel, 
and therefore energy use and emissions, 
through 
the 
use 
of 
Internet-based 
communications tools. It has a policy of 
preferring 
devices 
with 
low 
energy 
consumption where a choice is available, and 
switching them off when not in use. 
 
Principal Risks and Uncertainties 
 
The Group operates in an uncertain environment and is subject to a number of risk factors. The Directors 
have carried out a robust assessment of the principal risks facing the Group, including those that threaten 
its business model, future performance, solvency or liquidity. They consider the following risk factors 
are of particular relevance to the Group’s activities and to any investment in the Group. It should be noted 
that the list is not exhaustive and that other risk factors not presently known or currently deemed 
immaterial may apply. 
 
The risk factors are summarised below: 
 
Risks relating to the Group’s business strategy 
 
The Group’s business is relatively undeveloped 
 
The operations of Hemogenyx Pharmaceuticals are at a relatively early stage and, to date, no commercial 
sales of its products have been made. The ability of the Group to achieve commercialisation is dependent 
on a number of factors, many of which are outside of the Group’s control. Examples of factors outside of 
the Group’s control are capital market conditions, FDA approval and competition. 
 
Business strategy of the Group 
 
The development of clinical products for new medical treatments is inherently uncertain, with high failure 
rates in clinical studies for both early and late-stage development products and such clinical studies can 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
16 
be expensive, time-consuming and complicated and there is no certainty as to the outcome of such 
studies. Even once clinical studies have been successfully carried out, later phase trials may not 
successfully replicate or improve on such outcomes. 
 
Staffing and key personnel 
 
The Group is reliant on a number of the key personnel, in particular Dr Vladislav Sandler who is the 
founder of Hemogenyx Pharmaceuticals (refer to Corporate Governance Report for further detail). Whilst 
the Group has endeavoured to ensure that it has contractual arrangements which include non-compete 
restrictions in place with such persons to lessen the risk of them ceasing to be involved with the Group, 
in the event that the Group was to lose the services of such individuals, its results could be adversely 
affected.  
 
Costs of commercialisation 
 
The ability of the Group to bring its products to first commercial sale will be dependent in part on the 
overall costs of manufacturing and the costs involved could be significant and there is no guarantee that 
the sale prices achievable for its products will be viable and sustainable. 
 
Clinical studies and timelines risk 
 
Hemogenyx Pharmaceuticals is currently progressing its product candidates through preclinical 
development and the first stages of clinical trials. Although encouraging results have been achieved so 
far, there can be no certainty that these results can be reproduced in clinical trials and as existing clinical 
trial progresses. The monies raised in Placings and Subscriptions support those preclinical and clinical 
development activities. 
 
The development of clinical products for new medical treatments is inherently uncertain, with high 
failure rates in clinical studies for both early- and late-stage development products. Furthermore, such 
clinical studies (Phase 1, Phase 2a/2b, Phase 3) are typically expensive, complex, can take considerable 
time to complete and have uncertain outcomes. 
 
Furthermore, as a result of adverse, undesirable, unintended or inconclusive results from any testing or 
clinical trials, the future progress, planning and potential treatment outcome of the products and clinical 
programmes may be affected and may potentially prevent or limit the commercial use of one, many or 
all of the Company's products. In addition, later phase clinical trials may fail to show the desired 
safety and efficacy obtained in earlier studies, and a successful completion of one stage of clinical 
development of an investigational clinical product does not ensure that subsequent stages of clinical 
development will be successful. 
 
Failure can occur at any stage of clinical development and, as a result, enforced delays to the clinical 
development plan could delay or prevent commercialisation of the Company's product candidates. 
Various factors associated with the potential failure or delay in completing a clinical programme include, 
but are not limited to: 
§ Delays in securing clinical investigators or clinical study sites; 
§ Delays in securing any regulatory authority, hospital ethics committee, or institutional review 
board approval or approvals necessary to commence a clinical study; 
§ Delays or failure to recruit a sufficient number of clinical study participants in accordance with 
the clinical study protocol; 
§ Difficulty or inability to monitor subjects adequately during or after treatment; 
§ Inability to replicate in Phase 3 controlled studies any safety and efficacy data obtained from 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
17 
controlled Phase 2a/2b clinical studies; 
§ Difficulty or inability to secure clinical investigator compliance to follow the approved clinical 
study protocol; and 
§ Unexpected adverse events or any other safety or related issues. 
 
Research and development risk 
 
The Group operates in the biotechnology and bio-pharmaceutical development sectors and carries out 
complex scientific research. If the research or preclinical testing or clinical trials of any of Hemogenyx 
Pharmaceuticals’ product candidates fail, meaning that these candidates will not be licensed or marketed, 
this would result in a complete absence of revenue from these failed candidates. Positive results from 
preclinical and early clinical studies do not guarantee positive results from clinical trials required to 
permit application for regulatory approval. Furthermore, the Group may discontinue the development 
of candidates if results are not positive or unlikely to further its progress towards a meaningful outcome 
or collaboration. 
 
Intellectual property (IP) infringement 
 
The Group may be subject to future litigation concerning its own IP and the IP of others. Adverse 
judgements in relation to its IP would likely have negative outcomes for its results of operations. 
 
Intellectual property (IP) control 
 
The Group is partially reliant on an exclusive, world-wide licence of a patent from Cornell University for 
its Hu-PHEC line of business. The exclusivity and exploitable territory for this licence depend on the Group 
meeting various developmental milestones. 
 
Environmental and other regulatory requirements 
 
The event of a breach with any environmental or regulatory requirements may give rise to reputational, 
financial or other sanctions against the Group, and therefore the Board considers these risks seriously and 
designs, maintains and reviews its policies and processes so as to mitigate or avoid these risks. Whilst the 
Board has a good record of compliance, there is no assurance that the Group’s activities will always be 
compliant. 
 
Financing 
 
The Group’s ability to develop its products through to commercial sales will depend upon the Group’s 
ability to obtain financing primarily through a further raising of new equity capital. Although the Group 
has been successful in raising new equity capital, there can be no guarantee that it will be able to do so in 
the future. The Group may not be successful in procuring the requisite funds on terms which are 
acceptable to it (or at all) and, if such funding is unavailable, would raise questions over its ability to 
further develop its products through to commercialisation. Further, Shareholders’ holdings of Ordinary 
Shares may be materially diluted if debt financing is not available. 
 
Market conditions 
 
Market conditions, including general economic conditions and their effect on exchange rates, interest 
rates and inflations rates, may impact the ultimate value of the Group regardless of its operating 
performance. The Group also faces competition from other organisations, some of which may have 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
18 
greater resources or be more established in a particular territory. The Board considers and reviews all 
market conditions to try and mitigate any risks that may arise from these. 
 
Political and country risk  
 
The departure of the UK from the EU is now complete and its impact on the business, whose current 
operations are principally in the US, has been negligible. Any further changes in international trade, tariff 
and import/export regulations may impose unexpected duty costs or other non-tariff barriers on the 
Group. The Company is monitoring matters and will seek advice, where necessary, as to how to mitigate 
the risks arising. The Company has not experienced and does not anticipate that there will be any impact, 
including on its personnel or supply chain, as a result of the on-going war in Ukraine or the situation in 
the Middle East save for a general increase in inflation such as of the cost of energy.

Directors’ Report for the year ended 31 December 2024 
The Directors present their report with the audited financial statements of the Group for the year ended 
31 December 2024. 
 
The Company’s Ordinary Shares were admitted to listing on the London Stock Exchange under the name 
Silver Falcon plc, on the Official List pursuant to Chapters 14 of the Listing Rules, which sets out the 
requirements for Standard Listings, on 9 November 2015. 
 
On 4 October 2017 the Company’s shareholders voted in favour of acquiring the biotechnology company 
Hemogenyx Pharmaceuticals Limited, with shares being readmitted to trading on 5 October 2017 under 
the name Hemogenyx Pharmaceuticals plc. 
 
Principal Activity 
 
The Group’s principal activity is the discovery, development and commercialisation of a suite of products 
to address current problems associated with the treatment of blood disorders such as cancers and 
autoimmune diseases, and with viral infections. Hemogenyx Pharmaceuticals’ distinct and 
complementary products include immunotherapy product candidates for the treatment of AML and other 
blood malignancies and potentially patient conditioning for bone marrow transplantation (the CDX bi-
specific antibody and CAR-T therapy). Each of these products holds the potential to revolutionise the 
way diseases of the blood are treated, offering solutions that mitigate the dangers and limitations 
associated with the current standard of care. Additionally, the Group has two platform technologies: its 
Advanced peripheral blood Hematopoietic Chimeras, a form of humanised mouse used to model diseases 
including autoimmune conditions and to test multi-specific antibody treatments; and Chimeric Bait 
Receptors or CBR, a novel way to create constructs potentially capable of programming immune cells to 
attract and destroy a wide range of viruses and malignant (cancer-causing) cells. 
 
The Group has two companies that are located outside of the UK. The principal laboratory of the Group 
is located in Manhattan, New York, USA. 
 
Results and Dividends 
 
The Consolidated Statement of Comprehensive Income set out on page 46 shows a loss for the year 
amounting to £5,625,478 (2023: £6,696,493). The Directors do not propose a dividend in respect of the 
year ended 31 December 2024 (31 December 2023: nil).

The Corporate Governance report is disclosed on page 26. 
 
Going Concern 
 
The Company’s business activities, together with facts likely to affect its future operations and financial 
and liquidity positions are set out in the Chairman’s Statement and Directors’ Strategic Report on pages 3 
and 10 respectively. In addition, Note 22 to the financial statements discloses the Company’s capital risk 
management policy and Note 2 details further considerations made by the Directors in respect of going 
concern. 
 
The Directors, having made due and careful enquiry, are of the opinion that the Company has or will have 
access to sufficient funding in order to execute its operations over the next 12 months, however a material 
uncertainty exists. The Directors have made an informed judgment, at the time of approving the financial 
statements, that there is a reasonable expectation that the Company has adequate resources to continue in 
operational existence for the foreseeable future, however this relies upon the Company raising additional 
capital. As a result, the Directors have adopted the going concern basis of accounting in the preparation of 
the annual financial statements. 
 
Political Donations 
 
The Group made no political donations during the year (2023: £nil). 
 
Charitable Donations 
 
There were no charitable donations made by the Group in the current or prior year. 
 
Greenhouse gas emissions 
 
The Company used less than 40,000kWh of energy in the United Kingdom during 2024 and therefore 
does not report on energy consumption and emissions under the Companies (Directors’ Report) and 
Limited Liability Partnerships (Energy and Carbon Report) Regulations 2018.

Statement of Directors’ Responsibilities 
 
The Directors are responsible for preparing the Annual Report and the financial statements in accordance 
with applicable law and regulations. 
 
Company law requires the Directors to prepare financial statements for each financial year. Under that 
law the Directors have elected to prepare the Group and Company financial statements in accordance 
with UK-adopted international accounting standards. 
 
Under Company law the Directors must not approve the financial statements unless they are satisfied that 
they give a true and fair view of the state of affairs of the Group and Company and of the profit or loss of 
the Group for that year. 
 
In preparing these financial statements, the Directors are required to: 
• Select suitable accounting policies and then apply them consistently; 
• Make judgments and accounting estimates that are reasonable and prudent; 
• State whether applicable UK-adopted international accounting standards have been followed, 
subject to any material departures disclosed and explained in the financial statements; and 
• Prepare the financial statements on the going concern basis unless it is inappropriate to presume 
that the Group and Company will continue in business. 
 
The Directors are responsible for keeping adequate accounting records that are sufficient to show and 
explain the Group and parent company’s transactions and disclose with reasonable accuracy at any time 
the financial position of the Group and parent company and enable them to ensure that the financial 
statements and the Directors’ remuneration report comply with the Companies Act 2006. They are also 
responsible for safeguarding the assets of the Group and parent company and hence for taking reasonable 
steps for the prevention and detection of fraud and other irregularities. They are also responsible to make 
a statement that they consider that the annual report and accounts, taken as a whole, is fair, balanced, and 
understandable and provides the information necessary for the shareholders to assess the Group and 
parent company’s position and performance, business model and strategy.  
 
The Directors are responsible for the maintenance and integrity of the corporate and financial information 
included on the Company’s website. Legislation in the United Kingdom governing the preparation and 
dissemination of the financial statements may differ from legislation in other jurisdictions. 
 
Directors’ Responsibility Statement Pursuant to Disclosure and Transparency Rules 
 
Each of the Directors, whose names and functions are listed on page 1, confirms that, to the best of their 
knowledge and belief: 
 
• the group and company financial statements have been prepared in accordance with UK-
adopted international accounting standards, and give a true and fair view of the assets, 
liabilities, financial position and loss of the Group; and  
• the Annual Report and financial statements, including the Business review, includes a fair 
review of the development and performance of the business and the position of the Group and 
parent company, together with a description of the principal risks and uncertainties that they 
face.

Disclosure of Information to Auditors 
 
So far as the Directors are aware, there is no relevant audit information of which the Company’s auditors 
are unaware, and each Director has taken all the steps that he ought to have taken as a Director in order 
to make himself aware of any relevant audit information and to establish that the Company’s auditors are 
aware of that information.

Governance Report 
Introduction 
 
The Company recognises the importance of, and is committed to, high standards of Corporate 
Governance. The Company has voluntarily applied the main and supporting principles set out in the UK 
Code of Corporate Governance published by the Financial Reporting Council in 2018 ("the Code"). The 
Code has been followed to the extent practicable for a company of its size and nature. The Code can be 
found 
at 
https://www.frc.org.uk/library/standards-codes-policy/corporate-governance/uk-corporate-
governance-code. The ways in which the Company has applied the Code are explained below: 
§ The Code requires that a smaller company should have at least two Independent Non-Executive 
Directors. As at 31 December 2024 the Board consisted of an Executive Director and three Non-
Executive Directors. The Non-Executive Directors are interested in either ordinary shares in the 
Company, options over ordinary shares in the Company, or both, and cannot therefore be 
considered fully independent under the Code. The remuneration of the Non-Executive Directors 
includes options and this is contrary to best practice, and thus the Company is not in full 
compliance. However, the Directors consider the present structure and arrangements to be 
adequate given the size and stage of development of the Company, and all are considered to be 
independent in character and judgement. 
§ Directors appointed by the Board are subject to election by shareholders at the Annual General 
Meeting of the Company following their appointment and thereafter are subject to re-election in 
accordance with the Company’s articles of association. The terms and conditions of appointment 
of Non-Executive Directors will be made available upon written request. 
 
The Board has voluntarily adopted a code for Directors’ dealings based on the Model Code contained in 
the Listing Rules of the UK Listing Authority that was previously in force. The Board will be responsible 
for taking all proper and reasonable steps to ensure compliance with the code by the Directors. 
Compliance with the code is being undertaken on a voluntary basis and the FCA will not have the authority 
to (and will not) monitor the Company’s voluntary compliance with it, nor to impose sanctions in respect of 
any failure by the Company to so comply. In addition, the Company will take all proper and reasonable 
steps to ensure compliance by the Founders with the Code for dealings in the Ordinary Shares. 
 
The Company is small with a modest resource base. The Company has a clear mandate to optimise the 
allocation of limited resources to support its development plans. As such, the Company strives to maintain 
a balance between conservation of limited resources and maintaining robust corporate governance 
practices. As the Company evolves, the Board is committed to enhancing the Company’s corporate 
governance policies and practices deemed appropriate for the size and maturity of the organisation. 
 
Set out below are the Company’s corporate governance practices for the year ended 31 December 2024. 
 
Committees 
 
The Company has established audit, remuneration and nomination committees. 
Audit Committee 
 
The Audit Committee has responsibility for, among other things, the monitoring of the integrity of the 
financial statements of the Company and its Group and the involvement of the Group's auditors in that 
process. It focuses in particular on compliance with accounting policies and ensuring that an effective 
system of external audit and financial control is maintained, including considering the scope of the annual 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
25 
audit and the extent of the non-audit work undertaken by external auditors and advising on the 
appointment of external auditors. The ultimate responsibility for reviewing and approving the annual 
report and accounts and the half-yearly reports remains with the Board. The Audit Committee will meet 
at least three times a year at the appropriate times in the financial reporting and audit cycle. 
 
The members of the Audit Committee are Peter Redmond, who acts as chairman of the committee, and 
Professor Sir Marc Feldmann. 
 
The Group’s external auditor is PKF Littlejohn LLP who has served as external auditor for ten years. The 
role of external auditor last went to tender in 2015 and a tender process will be undertaken in 2025 in 
respect of the year ended 31 December 2025. The Audit Committee closely monitors the level of audit 
and non-audit services that it provides to the Company and Group. 
 
During the year to 31 December 2024 the Audit Committee considered the following key issues in 
relation to the Financial Statements: 
 
Issue 
Action 
• 
Accounting policies 
The Committee reviewed and discussed the significant 
accounting policies with management and the external auditor and 
reached the conclusion that each policy was appropriate to the 
Group. 
• 
Carrying value of investment in 
Hemogenyx Pharmaceuticals LLC 
The Committee reviewed the impairment assessment report 
prepared by management and agreed that given the reasonable 
expectation that the Group will achieve its milestone targets over 
the next 18 months no impairment to the value of the investment 
in Hemogenyx Pharmaceuticals LLC was required as at 31 
December 2024. 
• 
Carrying 
value 
of 
licensed 
intangible assets 
The Committee reviewed the impairment assessment report 
prepared by management and agreed that given the licenses are 
still active and the licensing parties have not expressed a want to 
revoke the Company’s rights no impairment to the value of 
licensed intangible assets, being rights to certain intellectual 
property of Cornell University and Eli Lilly and Company, was 
required as at 31 December 2024. 
• 
Going concern review 
The Committee considered the ability of the Group to operate as 
a Going Concern considering cash flow forecasts for the next 12 
months and milestone achievements. It was determined by the 
Committee that it was reasonable to expect that the Group has or 
will have access to sufficient funding in order to achieve its 12-
month milestone targets and that it was appropriate for the 
Financial Statements to be prepared on a going concern basis. 
• 
Review of audit and non-audit 
services and fees 
The external auditor is not engaged by the Group to carry out any 
non-audit work in respect of which it might, in the future, be 
required to express an audit opinion. 
The Committee reviewed the fees charged for the provision of 
audit and non-audit services and determined that they were in line 
with fees charged to companies of similar size and stage of 
development. 
The Committee considered and was satisfied the external 
auditor’s assessment of its own independence.

Remuneration Committee 
 
The remuneration committee reviews the performance of the Executive Directors and makes 
recommendations to the Board on matters relating to their remuneration and terms of employment. The 
committee also makes recommendations to the Board on proposals for the granting of share awards and 
other equity incentives pursuant to any share award scheme or equity incentive scheme in operation from 
time to time. The Remuneration Committee will meet at least twice a year. 
 
The members of the Remuneration Committee are Peter Redmond, who acts as chairman of the 
committee, and Alexis Sandler. 
Nomination Committee 
 
The Nomination Committee is responsible for considering and making recommendations to the Board in 
respect of appointments to the Board, the Board committees and the chairmanship of the Board 
committees. It is also responsible for keeping the structure, size and composition of the Board under 
regular review, and for making recommendations to the Board with regard to any changes necessary, 
taking into account the skills and expertise that will be needed on the Board in the future. The Nomination 
Committee meets at least once a year. 
 
The members of the Nomination Committee are Peter Redmond, who acts as chairman of the committee, 
Professor Sir Marc Feldmann, and Alexis Sandler. 
 
Leadership 
 
The Company is headed by an effective Board which is collectively responsible for the long-term success 
of the Company. 
 
The role of the Board: the Board sets the Company’s strategy, ensuring that the necessary resources are 
in place to achieve the agreed strategic priorities, and reviews management and financial performance. It 
is accountable to shareholders for the creation and delivery of strong, sustainable financial performance 
and long-term shareholder value. To achieve this, the Board directs and monitors the Company’s affairs 
within a framework of controls which enable risk to be assessed and managed effectively. The Board also 
has responsibility for setting the Company’s core values and standards of business conduct and for 
ensuring that these, together with the Company’s obligations to its stakeholders, are widely understood 
throughout the Company. The Board has a formal schedule of matters reserved which is provided later 
in this report. 
 
Board Meetings: the core activities of the Board are carried out in scheduled meetings of the Board. These 
meetings are timed to link to key events in the Company’s corporate calendar and regular reviews of the 
business are conducted. Additional meetings and conference calls are arranged to consider matters which 
require decisions outside the scheduled meetings. During the year, the Board met formally on 12 
occasions. 
 
Outside the scheduled meetings of the Board, the Directors maintain frequent contact with each other to 
discuss any issues of concern they may have relating to the Company or their areas of responsibility, and 
to keep them fully briefed on the Company’s operations. 
 
Matters reserved specifically for the Board: the Board has a formal schedule of matters reserved that can 
only be decided by the Board. The key matters reserved are the consideration and approval of:

• The Company’s overall strategy; 
• Financial statements and dividend policy; 
• Management structure including succession planning, appointments and remuneration; 
material acquisitions and disposal, material contracts, major capital expenditure projects and 
budgets; 
• Capital structure, debt and equity financing and other matters; 
• Risk management and internal controls; 
• The Company’s corporate governance and compliance arrangements; and 
• Corporate policies 
 
Summary of the Board’s work in the year: during the year, the Board considered all relevant matters 
within its remit, but focused in particular on the development and risk diversification of the Company.

The Board is pleased with the high level of attendance and participation of Directors at Board and 
committee meetings. 
 
The Chairman sets the Board Agenda and ensures adequate time for discussion. 
 
Non-Executive Directors: the Non-Executive Directors bring a broad range of business and commercial 
experience to the Company and have a particular responsibility to challenge independently and 
constructively the performance of the Executive management (where appointed) and to monitor the 
performance of the management team in the delivery of the agreed objectives and targets. 
 
All directors with the exception of the CEO and Professor Sir Marc Feldmann were appointed for an 
initial term of 12 months. These terms were extended by mutual agreement after satisfactory performance 
and re-election by shareholders. 
 
Other governance matters: all of the Directors are aware that independent professional advice is available 
to each Director in order to properly discharge their duties as a Director. In addition, each Director and 
Board committee has access to the advice of the Company Secretary. 
 
The Company Secretary: the Company Secretary during the year was Ben Harber. Westend Corporate 
LLP were appointed on 1 January 2025. They are responsible for the Board complying with UK 
procedures. 
 
Effectiveness 
 
For the period under review the Board comprised a Chief Executive Officer, a Non-Executive Chairman, 
and two independent Non-Executive Directors. Biographical details of the Board members are set out on 
page 8 of this report. 
 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
28 
The Directors are of the view that the Board and its committees consist of Directors with an appropriate 
balance of skills, experience, independence and diverse backgrounds to enable them to discharge their 
duties and responsibilities effectively. 
 
Independence: the Non-Executive Directors bring a broad range of business and commercial experience 
to the Company. The Board considers each of the Non-Executive Directors to be independent in character 
and judgement. 
 
Appointments: the Board is responsible for reviewing and the structure, size and composition of the Board 
and making recommendations to the board with regards to any required changes. 
 
Commitments: all Directors have disclosed any significant commitments to the Board and confirmed that 
they have sufficient time to discharge their duties. 
 
Induction: all new Directors received an induction as soon as practical on joining the Board. 
 
Conflict of interest: a Director has a duty to avoid a situation in which he or she has, or can have, a direct or 
indirect interest that conflicts, or possibly may conflict with the interests of the Company. The Board had 
satisfied itself that there is no compromise to the independence of those Directors who have appointments 
on the Boards of, or relationships with, companies outside the Company. The Board requires Directors 
to declare all appointments and other situations which could result in a possible conflict of interest. 
 
Board performance and evaluation: Hemogenyx Pharmaceuticals plc has a policy of appraising Board 
performance annually. Having reviewed various approaches to Board appraisal, it has concluded that for 
a company of its current scale, an internal process in which all Board members submit answers to a 
questionnaire that considers the functionality of the Board and its committees is most appropriate at this 
stage. 
 
Accountability 
 
The Board is committed to providing shareholders with a clear assessment of the Company’s position 
and prospects. This is achieved through this report and as required in other periodic financial and trading 
statements. 
 
Going concern: the Company’s business activities, together with factors likely to affect its future 
operations, financial position, and liquidity position are set out in the Chairman’s Statement and the 
principal risks and uncertainties sections of the Directors’ Strategic Report. In addition, the Notes to the 
Financial Statements disclose the Company’s financial risk management practices with respect to its 
capital structure, liquidity risk, interest rate risk, credit risk, and other related matters. 
 
The Directors, having made due and careful enquiry, are of the opinion that the Company has or will have 
adequate working capital to execute its operations and has the ability to access additional financing over 
the next 12 months. The Directors, therefore, have made an informed judgement, at the time of approving 
financial statements, that there is a reasonable expectation that the Company has adequate resources to 
continue in operational existence for the foreseeable future. As a result, the Directors have continued to 
adopt the going concern basis of accounting in preparing the annual financial statements. 
 
Internal controls: the Board of Directors reviews the effectiveness of the Company’s system of internal 
controls in line with the requirement of the Code. The internal control system is designed to manage the 
risk of failure to achieve its business objectives. This covers internal financial and operational controls, 
compliances and risk management. The Company has necessary procedures in place for the year under 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
29 
review and up to the date of approval of the Annual Report and financial statements. The Directors 
acknowledge their responsibility for the Company’s system of internal controls and for reviewing its 
effectiveness. The Board confirms the need for an ongoing process for identification, evaluation and 
management of significant risks faced by the Company. The Directors carry out a risk assessment before 
signing up to any commitments. 
 
Workforce policies and practices 
 
The Board is responsible for ensuring that workforce policies and practices are consistent with the 
Group’s values and support its long-term sustainable success, and that staff are able to raise any matters 
of concern. The Non-executive Director designated to engage with the workforce on these matters is 
Alexis Sandler. Ms Sandler, and in turn the Board, review the Group’s policies and procedures, including 
anti-harassment and discrimination policies, sexual harassment reporting procedures, and procedures for 
reporting grievances or other concerns, and oversee the proportionate and independent investigation of 
any matters arising from them. These policies are provided to workers prior to the start of their work with 
the Group, and hard copies are posted prominently in the Group’s operating premises together with other 
legally required notices. 
 
Relations with stakeholders 
 
The Company is committed to a continuous dialogue with shareholders as it believes that this is essential 
to ensure a greater understanding of and confidence amongst its shareholders in the medium- and longer-
term strategy of the Group and in the Board’s ability to oversee its implementation. It is the responsibility 
of the Board as a whole to ensure that a satisfactory dialogue takes place. 
 
Section 172 of the Companies Act 2006 requires Directors to take into consideration the interests of 
stakeholders in their decision making. The Board is committed to understanding and engaging with all 
key stakeholder groups of the Company in order to maximise value and promote long-term Company 
success in line with our strategic objectives. The Board recognises its duties under Section 172 and 
continuously has regard to how the Company’s activities and decisions will impact employees, those with 
which it has a business relationship, the community and environment and its reputation for high standards 
of business conduct. In weighing all of the relevant factors, the Board, acting in good faith and fairly 
between members, makes decisions and takes actions that it considers will best lead to the long-term 
success of the Company. 
 
During the year, the Board assessed its current activities between the Board and its stakeholders, which 
demonstrated that the Board actively engages with its stakeholders and takes their various objectives into 
consideration when making decisions. Specifically, actions the Board has taken to engage with its 
stakeholders in 2024 include: 
• Attended the 2024 AGM and GM, and prepared to answer any questions raised by shareholders; 
• Arranged meetings with certain stakeholders to provide them with updates on the Company’s 
research and development activities and other general corporate updates; 
• Made presentations at conferences and published recordings and slide decks on the Company’s 
research and development; 
• Evaluated the relationships with the Company’s various collaborators through management and 
identified ways to strengthen relationships and arrangements with key collaborations; and 
• Monitored company culture and engaged with employees on efforts to continuously improve 
company culture and morale.

Year Ended 31 December 2024

The Board believes that appropriate steps and considerations have been taken during the year so that each 
Director has an understanding of the various key stakeholders of the Company. The Board recognises its 
responsibility to contemplate all such stakeholder needs and concerns as part of its discussions, decision-
making, and in the course of taking actions, and will continue to make stakeholder engagement a top 
priority in the coming years. 
 
The Board’s primary shareholder contact is through Peter Redmond, the Non-Executive Director 
responsible for shareholder relations. The Chairman, the CEO and other Directors, as appropriate, make 
themselves available for contact with major shareholders and other stakeholders in order to understand 
their issues and concerns. 
 
The Company plans to use the AGM as an opportunity to communicate with its shareholders. Notice of 
the AGM will be issued shortly and at least 21 days before the date of the meeting. To ensure compliance 
with the Governance Code, the Board proposes separate resolutions for each issue, and proxy forms allow 
shareholders who are unable to attend the AGM to vote for or against or to withhold their vote on each 
resolution. The results of all proxy voting will be published on the Group’s web site after the AGM. 
Shareholders who attend the AGM will have the opportunity to ask questions. 
 
The Group’s web site at https://hemogenyx.com is the primary source of information on the Group. The 
web site includes an overview of the activities of the Group and all recent Group announcements. 
 
Viability statement 
 
In accordance with the UK Corporate Governance Code published in July 2018, the Directors have 
assessed the prospects of the Group and concluded that it is appropriate to adopt the going concern basis 
of accounting based on the amount of cash on hand at the end of the year and at the time of publication 
of this report. The assessment of going concern is disclosed in Note 2.  
 
The Board’s assessment of the Group’s current position and principal risks are disclosed in the Directors’ 
Strategic Report on page 8 of this report.

Directors’ Remuneration Report 
The Company has an established remuneration committee. The Committee reviews the scale and structure 
of the Directors’ fees, taking into account the interests of shareholders and the performance of the 
Company and directors. 
 
The items included in this report are unaudited unless otherwise stated. 
 
Statement of Hemogenyx Pharmaceutical plc’s Policy on Directors’ Remuneration by the 
Chairman of the Remuneration Committee 
 
As Chairman of the Remuneration Committee I am pleased to introduce our Directors’ Remuneration 
Report. One of the Remuneration Committee’s aims is to provide clear, transparent remuneration 
reporting for our shareholders which adheres to the best practice corporate governance principles that are 
required for listed organisations. 
 
The Directors’ Remuneration Policy, which is set out on page 32 of this report, will be submitted to 
shareholders for approval at our Annual General Meeting. 
 
A key focus of the Directors’ Remuneration Policy is to align the interests of the Directors to the long-
term interests of the shareholders and aims to support a high-performance culture with appropriate reward 
for superior performance, without creating incentives that will encourage excessive risk taking or 
unsustainable company performance. This is underpinned through the implementation and operation of 
incentive plans. 
 
Key Activities of the Remuneration Committee 
 
The key activities of the Remuneration Committee are: 
§ to determine and agree with the Board the framework or broad policy for the remuneration of the 
Company’s chairman, chief executive, the executive directors, the company secretary and such 
other members of the executive management as it is designated to consider; 
§ in determining such policy, take into account all factors which it deems necessary including 
relevant legal and regulatory requirements, the provisions and recommendations of the UK 
Corporate Governance Code (the “Code”) and associated guidance. The objective of such policy 
shall be to ensure that members of the executive management of the Company are provided with 
appropriate incentives to encourage enhanced performance and are, in a fair and responsible 
manner, rewarded for their individual contributions to the success of the Company;  
§ recommend and monitor the level and structure of remuneration for senior management; 
§ when setting remuneration policy for directors, review and have regard to the remuneration 
trends across the Company, and review the on-going appropriateness and relevance of the 
remuneration policy; 
§ obtain reliable, up-to-date information about remuneration in other companies. To help it fulfil 
its obligations the Committee shall have full authority to appoint remuneration consultants and 
to commission or purchase any reports, surveys or information which it deems necessary, within 
any budgetary restraints imposed by the Board; 
§ be exclusively responsible for establishing the selection criteria, selecting, appointing and setting 
the terms of reference for any remuneration consultants who advise the Committee; 
§ approve the design of, and determine targets for, any performance related pay schemes operated 
by the Company and approve the total annual payments made under such schemes; 
§ review the design of all share incentive plans for approval by the Board and shareholders. For 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
32 
any such plans, determine each year whether awards will be made, and if so, the overall amount 
of such awards, the individual awards to executive directors, company secretary and other 
designated senior executives and the performance targets to be used; 
§ ensure that contractual terms on termination, and any payments made, are fair to the individual, 
and the Company, that failure is not rewarded and that the duty to mitigate loss is fully 
recognised; and 
§ oversee any major changes in employee benefits structures throughout the Company.

The components of Director remuneration that are considered by the Board for the remuneration of 
directors in future years are likely to consist of: 
• Base salaries 
• Pension and other benefits 
• Annual bonus 
• Share incentive arrangements 
 
The Executive Director has entered into a service agreement with the Company and the Non-Executive 
Directors have entered into letters of appointment with the Company. 
 
All such contracts impose certain restrictions as regards the use of confidential information and intellectual 
property and the Executive Director’s service contract imposes restrictive covenants which apply 
following the termination of the agreement. 
 
The Executive Director Dr Vladislav Sandler is entitled to pay at a rate of £1,500 per day for time spent in 
the UK on the Company’s business. In addition, Dr Sandler has a separate contract with Hemogenyx 
Pharmaceuticals LLC effective 1 September 2017 appointing him as CEO and Chief Scientific Officer of 
that company for an initial three-year term with automatic continuation and setting out his duties in relation 
to his day-to-day to work in connection with Hemogenyx Pharmaceuticals’ product candidates. Pursuant to 
this contract, Dr Sandler was entitled to receive $324,000 in March 2023 which rose to $389,000 in March 
2024 and four weeks’ holiday a year. Dr Sandler is also subject to certain non-compete and non-interference 
covenants in the event of its termination (subject to certain limited exceptions). Dr Sandler also has a separate 
contract with Immugenyx LLC effective from 1 January 2019 appointing him as CEO and Chief Scientific

Other Matters 
 
The Company does not currently have any annual or long-term incentive schemes or any other scheme 
interests in place for any of the Directors. 
 
The Company has established a workplace pension scheme but it does not presently have any employees 
qualifying under the auto-enrolment pension rules who have not opted out of the scheme. It makes 
matching contributions to a 401(k) pension plan for employees in the US of up to 4%. The Company has 
not paid out any excess retirement benefits to any Directors or past Directors. The Company has not paid 
any compensation to past Directors. 
 
Recruitment Policy 
 
Base salary levels will take into account market data for the relevant role, internal relativities, their 
individual experience and their current base salary. Where an individual is recruited at below market 
norms, they may be re-aligned over time (e.g. two to three years), subject to performance in the role. 
Benefits will generally be in accordance with the approved policy. 
 
For external and internal appointments, the Board may agree that the Company will meet certain 
relocation and/or incidental expenses as appropriate. 
 
Payment for Loss of Office 
 
The Committee will honour Executive Directors’ contractual entitlements. Service contracts do not 
contain liquidated damages clauses. If a contract is to be terminated, the Committee will determine such 
mitigation as it considers fair and reasonable in each case. There is no agreement between the Company 
and its Executive Directors or employees, providing for compensation for loss of office or employment 
that occurs because of a takeover bid. 
 
The Committee reserves the right to make additional payments where such payments are made in good 
faith in discharge of an existing legal obligation (or by way of damages for breach of such an obligation); 
or by way of settlement or compromise of any claim arising in connection with the termination of an 
Executive Director’s office or employment. 
 
Service Agreements and Letters of Appointment 
 
The Executive Director’s service agreement had an initial term of two years and may subsequently be 
terminated by the Company or the Executive Director by giving 6 months’ notice.

Historical share price performance comparison 
 
The chart below compares the share price performance (based on a notional investment of £100) of 
Hemogenyx Pharmaceuticals plc against the FTSE SmallCap and FTSE Techmark Mediscience for the 
period November 2015 to December 2024 calculated on a month end spot basis. The FTSE SmallCap has 
been chosen to provide a wider market comparator constituting companies of an appropriate size and the 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
36 
FTSE Techmark Mediscience chosen due to sector relevance: 
 
 
Hemogenyx Pharmaceuticals plc was listed in November 2015 (under the name Silver Falcon plc) and 
therefore no historical share price data exists prior to this period. There was also no data between 
December 2015 and October 2017 pending completion of a transaction. It is for these reasons that the

Annual Report & Financial Statements for the 
Year Ended 31 December 2024

Independent Auditor’s Report to the Members of Hemogenyx Pharmaceuticals Plc 
Opinion  
We have audited the financial statements of Hemogenyx Pharmaceuticals Plc (the ‘parent company’) and 
its subsidiaries (the ‘group’) for the year ended 31 December 2024 which comprise the Consolidated 
Statement of Comprehensive Income, the Consolidated and Company Statements of Financial Position, 
the Consolidated and Company Statements of Changes in Equity, the Consolidated and Parent Company 
Statements of Cash Flows and notes to the financial statements, including significant accounting policies. 
The financial reporting framework that has been applied in their preparation is applicable law and UK-
adopted international accounting standards and as regards the parent company financial statements, as 
applied in accordance with the provisions of the Companies Act 2006.  
In our opinion:  
• the financial statements give a true and fair view of the state of the group’s and of the parent 
company’s affairs as at 31 December 2024 and of the group’s loss for the year then ended;  
• the group financial statements have been properly prepared in accordance with UK-adopted 
international accounting standards;  
• the parent company financial statements have been properly prepared in accordance with UK-
adopted international accounting standards and as applied in accordance with the provisions of 
the Companies Act 2006; and  
• the financial statements have been prepared in accordance with the requirements of the Companies 
Act 2006.  
Basis for opinion  
We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and 
applicable law. Our responsibilities under those standards are further described in the Auditor’s 
responsibilities for the audit of the financial statements section of our report. We are independent of the 
group and parent company in accordance with the ethical requirements that are relevant to our audit of 
the financial statements in the UK, including the FRC’s Ethical Standard as applied to listed public 
interest entities, and we have fulfilled our other ethical responsibilities in accordance with these 
requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide 
a basis for our opinion.  
Material uncertainty related to going concern 
We draw attention to note 2 in the financial statements, which indicates that the group will need to obtain 
additional funding in order to complete its Phase 1 clinical development of CAR-T product, together with 
working capital requirements. As stated in note 2, these events or conditions, along with the other matters 
as set forth in note 2, indicate that a material uncertainty exists that may cast significant doubt on the 
group’s and company’s ability to continue as a going concern. Our opinion is not modified in respect of 
this matter. 
 
In auditing the financial statements, we have concluded that the directors’ use of the going concern basis 
of accounting in the preparation of the financial statements is appropriate. Our evaluation of the directors’ 
assessment of the group’s and company’s ability to continue to adopt the going concern basis of 
accounting included reviewing key assumptions and inputs used by management in their cash flow 
forecasts, checking mathematical accuracy, as well as discussing with management how they intend to 
fund the clinical trials. Furthermore, we have assessed the probability of obtaining additional sources of 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
38 
funds when required, along with an assessment of committed expenditure and those which are able to be 
deferred or tapered.  
 
In relation to the group’s and company’s reporting on how it has applied the UK Corporate Governance 
Code, we have nothing material to add or draw attention to in relation to: 
 
• the directors’ statement in the financial statements about whether the directors considered it 
appropriate to adopt the going concern basis of accounting; and 
• the directors' identification in the financial statements of the material uncertainty related to the 
entity’s ability to continue as a going concern over a period of at least twelve months from the 
date of approval of the financial statements. 
Our responsibilities and the responsibilities of the directors with respect to going concern are described 
in the relevant sections of this report. 
 
Our application of materiality  
For the purposes of determining whether the financial statements are free from material misstatement, we 
define materiality as the magnitude or nature of misstatement that makes it probable that the economic 
decisions of a reasonably knowledgeable person, relying on the financial statements, would be changed, 
or influenced. We also determine a level of performance materiality which we use to assess the extent of 
testing needed to reduce to an appropriately low level the probability that the aggregate of uncorrected 
and undetected misstatements exceeds materiality for the financial statements as a whole. 
Materiality for the group financial statements as a whole was set at £115,000 (2023: £132,000). This was 
calculated based on 2% of total expenses, which is unchanged from the prior year. Using our professional 
judgement, we have determined this to be the principal benchmark within the financial statements as it 
will be most relevant to stakeholders in assessing the financial performance of the group during its years 
of development as the group is not currently revenue generating. 
Materiality for the parent company financial statements as a whole was set at £22,000 (2023: £29,000) 
based on 2% of total expenses, which is unchanged from the prior year. We have determined this level 
of materiality for the parent company to gain sufficient coverage of expenses. 
Performance materiality for the group financial statements was set at £80,000 (2023: £92,400) and the 
parent company was set at £15,000 (2023: £20,300), being 70% of materiality for the financial statements 
as a whole. A benchmark of 70% for performance materiality, which is unchanged from the prior year, 
was applied to provide sufficient coverage of significant and residual risks. 
We agreed to report to those charged with governance all corrected and uncorrected misstatements we 
identified through our audit with a value in excess of £5,000 (2023: £6,600) for the group financial 
statements and £1,000 (2023: £1,450) for the parent company financial statements. We also agreed to 
report any other audit misstatements below that threshold that we believe warranted reporting on 
qualitative grounds. 
 
Our approach to the audit 
The scope of our audit was influenced by our application of materiality. The quantitative and qualitative 
thresholds for materiality determine the scope of our audit and the nature, timing, and extent of our audit 
procedures. 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
39 
The group includes the listed parent company and its US-based subsidiaries. We assessed the structure 
of the group, its accounting processes and controls, and the industry in which it operates in order to 
determine the scope of our audit work and ensure that we obtained sufficient and appropriate audit 
evidence on which to base our group audit opinion. Those entities of the group which were considered to 
be material components, being the parent company and the subsidiary Hemogenyx Pharmaceuticals LLC, 
were subject to full scope audit procedures by us. We did not rely on the work of any component auditors. 
Procedures were performed to address the assessed risks of material misstatement at component level. 
As part of our planning, we assessed the risk of material misstatement including those that required 
significant auditor consideration at the component and group level. Procedures were then performed to 
address the risk identified and for the most significant assessed risks of material misstatement. The 
procedures performed are outlined below in the key audit matters section of this report. 
Key audit matters  
Key audit matters are those matters that, in our professional judgment, were of most significance in our 
audit of the financial statements of the current period and include the most significant assessed risks of 
material misstatement (whether or not due to fraud) we identified, including those which had the greatest 
effect on: the overall audit strategy, the allocation of resources in the audit; and directing the efforts of 
the engagement team. These matters were addressed in the context of our audit of the financial statements 
as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. 
In addition to the matter described in the Material uncertainty related to going concern section we have 
determined the matter described below to be the key audit matters to be communicated in our report. 
Key Audit Matter 
How our scope addressed this matter 
Carrying value of investments in, and 
loans to, subsidiary undertakings (Parent 
company only – Note 2, Note 13 and Note 
14) 
 
Investments held by the parent company 
in subsidiaries, as at 31 December 2024, 
totalled £8,000,000 in the Company 
Statement of Financial Position. Loans to 
those subsidiaries, as at 31 December 
2024, are reported as £21,862,118. 
These are significant balances due to the 
parent 
company. 
If 
the 
subsidiary 
undertakings are unable to generate 
sufficient future profits in the foreseeable 
future, there is a risk that both the 
investment and loans held in those entities 
are overstated. 
Given the aforementioned, the carrying 
value of investments in and loans to 
subsidiary undertakings was deemed to 
be a key audit matter. 
As part of our audit, we have performed the 
following procedures: 
• Reviewed 
and 
challenged 
the 
directors’ assessment of the carrying 
value of investments and loans to 
subsidiary undertakings, and their 
conclusions thereon; 
• Reviewed and assessed the subsidiary 
undertakings’ financial performance 
and 
development 
progress 
to 
corroborate the directors’ evaluation 
of recoverability; 
• Reviewed and assessed the current 
state of development, and scientific 
and commercial progress of the 
products under development; 
• Agreed ownership documents of all 
the subsidiaries in the group; and 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
40 
• Reviewed the market capitalisation of 
the group to provide further assurance 
of 
the 
carrying 
value 
of 
the 
investments and loans to subsidiary 
undertakings subsequent to the year 
end. 
Through the performance of the above 
testing, we conclude that management’s 
assessment of the carrying value of 
investments in, and loans to, subsidiary 
undertakings is reasonable. Recoverability is 
dependent on successful project 
development through the clinical trial phase 
and securing regulatory approval. 
 
Other information  
The other information comprises the information included in the Annual Report, other than the financial 
statements and our auditor’s report thereon. The directors are responsible for the other information 
contained within the annual report. Our opinion on the group and parent company financial statements 
does not cover the other information and, except to the extent otherwise explicitly stated in our report, 
we do not express any form of assurance conclusion thereon. Our responsibility is to read the other 
information and, in doing so, consider whether the other information is materially inconsistent with the 
financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be 
materially misstated. If we identify such material inconsistencies or apparent material misstatements, we 
are required to determine whether this gives rise to a material misstatement in the financial statements 
themselves. If, based on the work we have performed, we conclude that there is a material misstatement 
of this other information, we are required to report that fact.  
We have nothing to report in this regard.  
Opinions on other matters prescribed by the Companies Act 2006  
In our opinion the part of the directors’ remuneration report to be audited has been properly prepared in 
accordance with the Companies Act 2006. 
In our opinion, based on the work undertaken in the course of the audit: 
• the information given in the strategic report and the directors’ report for the financial year for 
which the financial statements are prepared is consistent with the financial statements; and  
• the strategic report and the directors’ report have been prepared in accordance with applicable 
legal requirements.  
Matters on which we are required to report by exception 
In the light of the knowledge and understanding of the group and the parent company and their 
environment obtained in the course of the audit, we have not identified material misstatements in the 
strategic report or the directors’ report.  
We have nothing to report in respect of the following matters in relation to which the Companies Act 
2006 requires us to report to you if, in our opinion:  

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
41 
• adequate accounting records have not been kept by the parent company, or returns adequate for 
our audit have not been received from branches not visited by us; or  
• the parent company financial statements and the part of the directors’ remuneration report to be 
audited are not in agreement with the accounting records and returns; or 
• certain disclosures of directors’ remuneration specified by law are not made; or  
• we have not received all the information and explanations we require for our audit. 
Corporate governance statement  
We have reviewed the directors' statement in relation to going concern, longer-term viability and that part 
of the Corporate Governance Statement relating to the group’s and parent company's compliance with 
the provisions of the UK Corporate Governance Code specified for our review by the Listing Rules.  
Based on the work undertaken as part of our audit, we have concluded that each of the following elements 
of the Corporate Governance Statement is materially consistent with the financial statements or our 
knowledge obtained during the audit: 
• Directors' statement with regards the appropriateness of adopting the going concern basis of 
accounting and any material uncertainties identified set out on page 21; 
• Directors’ explanation as to their assessment of the group’s prospects, the period this assessment 
covers and why the period is appropriate set out on page 30; 
• Directors’ statement on whether they have a reasonable expectation that the group will be able to 
continue in operation and meet its liabilities set out on page 54; 
• Directors' statement that they consider the annual report and the financial statements, taken as a 
whole, to be fair, balanced and understandable set out on page 22; 
• Board’s confirmation that it has carried out a robust assessment of the emerging and principal 
risks set out on page 15; 
• The section of the annual report that describes the review of effectiveness of risk management 
and internal control systems set out on page 27; and 
• The section describing the work of the audit committee set out on page 24. 
Responsibilities of directors  
As explained more fully in the statement of directors’ responsibilities, the directors are responsible for 
the preparation of the group and parent company financial statements and for being satisfied that they 
give a true and fair view, and for such internal control as the directors determine is necessary to enable 
the preparation of financial statements that are free from material misstatement, whether due to fraud or 
error.  
In preparing the group and parent company financial statements, the directors are responsible for 
assessing the group’s and the parent company’s ability to continue as a going concern, disclosing, as 
applicable, matters related to going concern and using the going concern basis of accounting unless the 
directors either intend to liquidate the group or the parent company or to cease operations, or have no 
realistic alternative but to do so.  
Auditor’s responsibilities for the audit of the financial statements  
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are 
free from material misstatement, whether due to fraud or error, and to issue an 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 (UK) will always detect a material misstatement when it exists.

Misstatements can arise from fraud or error and are considered material if, individually or in the 
aggregate, they could reasonably be expected to influence the economic decisions of users taken on the 
basis of these financial statements.  
Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design 
procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of 
irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, 
including fraud is detailed below: 
• We obtained an understanding of the group and parent company and the sector in which they 
operate to identify laws and regulations that could reasonably be expected to have a direct effect 
on the financial statements. We obtained our understanding in this regard through discussions 
with management, and application of our cumulative audit knowledge and experience of the 
sector.  
• We determined the principal laws and regulations relevant to the group and parent company in 
this regard to be those arising from the Companies Act 2006, Listing Rules, the Disclosure 
Guidance and Transparency Rules, the UK Corporate Governance Code and compliance with US 
Food and Drug Administration requirements. 
• We designed our audit procedures to ensure the audit team considered whether there were any 
indications of non-compliance by the group and parent company with those laws and regulations. 
These procedures included, but were not limited to: 
o Making inquiries of management; 
o Reviewing legal and professional fees; 
o Reviewing board and audit committee minutes; and 
o Reviewing regulated news service publications.  
• We also identified the potential risks of material misstatement of the financial statements due to 
fraud. We considered, in addition to the non-rebuttable presumption of a risk of fraud arising from 
management override of controls, that a potential for management bias exists in relation to the 
carrying value of investments in, and loans to, subsidiary undertakings - parent company. See key 
audit matters section above. 
• As in all our audits, we addressed the risk of fraud arising from management override of controls 
by performing audit procedures which included, but were not limited to: the testing of journals; 
reviewing accounting estimates for evidence of bias; and evaluating the business rationale of any 
significant transactions that are unusual or outside the normal course of business. 
• Compliance with laws and regulations at the subsidiary level was ensured through inquiry of 
management and review of correspondence for any instances of non-compliance. 
Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, 
including those leading to a material misstatement in the financial statements or non-compliance with 
regulation. This risk increases the more that compliance with a law or regulation is removed from the 
events and transactions reflected in the financial statements, as we will be less likely to become aware of 
instances of non-compliance. The risk is also greater regarding irregularities occurring due to fraud rather 
than error, as fraud involves intentional concealment, forgery, collusion, omission or misrepresentation. 
A further description of our responsibilities for the audit of the financial statements is located on the 
Financial Reporting Council’s website at: www.frc.org.uk/auditorsresponsibilities. This description 
forms part of our auditor’s report.  
Other matters which we are required to address  
We were first appointed by the audit committee to audit the financial statements for the period ended 31 
December 2015 and subsequent financial periods. Our total uninterrupted period of engagement is 10 
years, covering the periods ended 31 December 2015 to 31 December 2024.

The non-audit services prohibited by the FRC’s Ethical Standard were not provided to the group or the 
parent company and we remain independent of the group and the parent company in conducting our audit. 
Our audit opinion is consistent with the additional report to the audit committee.  
Use of our report 
This report is made solely to the company’s members, as a body, in accordance with Chapter 3 of Part 16 
of the Companies Act 2006.  Our audit work has been undertaken so that we might state to the company’s 
members those matters 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 members as a body, for our audit work, for this report, or for the opinions 
we have formed.

Notes to the Financial Statements 
1. General information 
 
The Group’s business is clinical-stage biotechnology focused on the discovery, development and 
commercialisation of innovative treatments relating to the treatment of blood cancers, certain solid 
cancers, autoimmune diseases, and viral infections. The products under development are designed to 
address a range of problems that occur with current standard of care treatments. 
 
The Company’s registered office is located at 6 Heddon Street, London, W1B 4BT, and the 
Company’s shares are listed on the main market of the London Stock Exchange. 
 
 
2. Summary of significant accounting policies 
 
The principal accounting policies applied in the preparation of these financial statements are set out 
below. These policies have been consistently applied to all the years presented, unless otherwise 
stated. 
 
Basis of preparation 
 
The financial statements have been prepared in accordance with UK-adopted international 
accounting standards and with requirements of the Companies Act 2006. The financial statements 
have been prepared under the historical cost convention. 
 
Basis of consolidation 
 
The consolidated financial statements comprise the financial statements of Hemogenyx 
Pharmaceuticals plc and its subsidiaries as at 31 December 2024. The financial statements of the 
subsidiaries are prepared for the same reporting period as the parent company, using consistent 
accounting policies. 
 
All intra-group balances, transactions, income and expenses and profits and losses resulting from 
intra-group transactions that are recognised in assets, are eliminated in full. 
 
Subsidiaries are fully consolidated from the date of acquisition, being the date on which the Group 
obtains control, and continue to be consolidated until the date that such control ceases. Hemogenyx 
Pharmaceuticals plc owns the majority of the shareholdings and has operational control over all its 
subsidiaries. Please refer to Note 14 for information on the consolidation of Hemogenyx 
Pharmaceuticals LLC. 
 
Hemogenyx Pharmaceuticals plc has used the exemption granted under s408 of the Companies Act 
2006 that allows for the non-disclosure of the Income Statement of the parent company. The after-
tax loss attributable to Hemogenyx Pharmaceuticals plc for the year ended 31 December 2024 was 
£638,537 (2023: loss of £1,620,638).

Research and development expenditure 
 
(i) 
Research and development 
Expenditure on research activities, undertaken with the prospect of gaining new scientific or 
technical knowledge and understanding, is expensed in profit or loss as incurred. Development 
activities involve a plan or design for the production of new or substantially improved products and 
processes. Development expenditures are capitalised only if development costs can be measured 
reliably, the product or process is technically and commercially feasible, future economic benefits 
are probable, and the Company intends to, and has sufficient resources to, complete development 
and to use or sell the asset. No development costs have been capitalised to date. 
 
(ii) 
Clinical trial expenses 
Clinical trial-related expenses are a component of the Company's research and development costs. 
These expenses include fees paid to contract research organisations, clinical sites, and other 
organisations who conduct development activities on the Company's behalf. The amount of clinical 
trial expenses recognised in the period related to clinical agreements is based on estimates of the 
work performed using an accrual basis of accounting. These estimates incorporate factors such as 
patient enrolment, services provided, contractual terms, and prior experience with similar contracts. 
 
Intangibles 
 
Research and development 
 
Research expenditure is written off as incurred. Development costs are capitalised only if the 
expenditure can be measured reliably, the product or process is technically and commercially 
feasible, future economic benefits are probable, the Group intends to and has sufficient resources to 
complete development and to use or sell the asset, and it is able to measure reliably the expenditure 
attributable to the intangible asset during its development. 
 
The Group’s view is that capitalised assets have a finite useful life and to that extent they should be 
amortised over their respective unexpired periods with provision made for impairment when 
required. Assets capitalised are not amortised until the associated product is available for use or sale. 
Amortisation is calculated using the straight-line method to allocate the costs of development over 
the estimated useful economic lives. Estimated useful economic life is assessed by reference to the 
remaining patent life and may be adjusted after taking into consideration product and market 
characteristics such as fundamental building blocks and product life cycle specific to the category of 
expenditure. 
 
Intellectual property (IP) 
 
IP assets (comprising patents, know-how, copyright and licences) acquired by the Group as a result 
of a business combination are initially recognised at fair value or as a purchase at cost and are 
capitalised. 
 
Internally generated IP costs are written off as incurred except where IAS 38 criteria, as described in 
research and development above, would require such costs to be capitalised. 
 
The Group’s view is that capitalised IP assets have a finite useful life and to that extent they should 
be amortised over their respective unexpired periods with provision made for impairment when 
required. Capitalised IP assets are not amortised until the Group is generating an economic return 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
54 
from the underlying asset and as such no amortisation has been incurred to date as the products to 
which they relate are not ready to be sold on the open market. When the trials are completed and the 
products attain the necessary accreditation and clearance from the regulators, the Group will assess 
the estimated useful economic like and the IP will be amortised using the straight-line method over 
their estimated useful economic lives. 
 
Fixed assets 
 
All property and equipment are stated at historical cost less accumulated depreciation or impairment 
value. Cost includes the original purchase price and expenditure that is directly attributable to the 
acquisition of the items to bring the asset to its working condition. Depreciation is provided at rates 
calculated to write off the cost less estimated residual value of each asset over its expected useful 
economic life. Right of Use assets are depreciated over their expected useful economic life on the 
same basis as owned assets, or where shorter, the lease term. Assets are reviewed for impairment 
when events or changes in circumstances indicate that the carrying amount may not be recoverable. 
 
The following rates are used: 
 
Computer equipment 
33% 
Straight-line 
Leasehold improvements 
12.5% 
Straight-line 
Property & equipment 
20% - 50% 
Straight-line 
 
Impairment of non-financial assets 
 
The Group is required to review, at least annually, whether there are indications (events or changes 
in circumstances) that non-financial assets have suffered impairment and that the carrying amount 
may exceed the recoverable amount. If there are indications of impairment, then an impairment 
review is undertaken. An impairment charge is recognised within operating costs for the amount by 
which the carrying amount exceeds its recoverable amount. The recoverable amount is the higher of 
the asset’s fair value less costs to sell and the value-in-use. In the event that an intangible asset will 
no longer be used, for example, when a patent is abandoned, the balance of unamortised expenditure 
is written off. 
 
Impairment reviews require the estimation of the recoverable amount based on value-in-use 
calculations. Non-financial assets relate typically to investments in related parties and in-process 
development and patents and require broader assumptions than for developed technology. Key 
assumptions taken into consideration relate to technological, market and financial risks and include 
the chance of product launch taking into account the stage of development of the asset, the scale of 
milestone and royalty payments, overall market opportunities, market size and competitor activity, 
revenue projections, estimated useful lives of assets (such as patents), contractual relationships and 
discount rates to determine present values of cash flows. 
 
Investments 
 
Equity investments in subsidiaries are held at cost, less any provision for impairment.  
 
Going concern 
 
The preparation of financial statements requires an assessment on the validity of the going concern 
assumption.

Year Ended 31 December 2024 
 
 
55 
The Company successfully raised £3.93 million (before expenses) through the allotment and issue 
of new ordinary shares during the year ended 31 December 2024, and a further £340 thousand in 
early 2025. These proceeds were raised in order to facilitate the progression of the Company's HG-
CT-1 product candidate into clinical trials and to enable the Company to continue development of 
product candidates for the treatment of viral infections and cancers based on its CBR platform. 
 
Funding will be required by the Company to complete Phase I clinical development. 
 
The Company cannot be certain that such additional funding will be available on acceptable terms, 
or at all. To the extent that the Company raises additional funds by issuing equity securities, the 
Company’s stockholders may experience dilution. Any debt financing, if available, may involve 
restrictive covenants. If the Company is unable to raise additional capital when required or on 
acceptable terms, it may have to (i) significantly delay, scale back or discontinue the development 
and/or commercialisation of one or more product candidates; (ii) seek collaborators for product 
candidates at an earlier stage than otherwise would be desirable and on terms that are less favourable 
than might otherwise be available; or (iii) relinquish or otherwise dispose of rights to technologies, 
product candidates or products that it would otherwise seek to develop or commercialise on 
unfavourable terms. 
 
The Directors are of the opinion that the Company has adequate working capital to execute its 
operations for the present time and is confident in its ability to access additional financing over the 
next 12 months, however a material uncertainty exists. The Directors, therefore, have made an 
informed judgement, at the time of approving these financial statements, that there is a reasonable 
expectation that the Company has adequate resources to continue in operational existence for the 
foreseeable future, however this relies upon the Company raising additional capital. The Directors have 
continued to adopt the going concern basis of accounting in preparing the annual financial statements. 
 
Trade and other receivables and payables 
 
Trade and other receivables are amounts due from customers for services performed in the ordinary 
course of business. If collection is expected in one year or less (or in the normal operating cycle of 
the business if longer), they are classified as current assets. If not, they are presented as non-current 
assets. 
 
Trade and other receivables are recognised initially at fair value and subsequently measured at 
amortised cost using the effective interest method, less provision for impairment. 
 
Other payables measured at amortised cost are obligations to pay for goods or services that have been 
acquired in the ordinary course of business from suppliers. The payables are classified as current 
payables if payment is due within one year or less (or in the normal operating cycle of the business if 
longer). If not, they are presented as non-current payables. 
 
The payables are recognised initially at fair value and subsequently measured at amortised cost using 
the effective interest method. 
 
Foreign currencies 
 
Functional and presentation currency 
The Company’s presentation currency is the British Pound Sterling (“£”). The functional currency 
for the Company, being the currency of the primary economic environment in which the Company 
operates, is the British Pound Sterling. The individual financial statements of each of the Company’s 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
56 
wholly owned subsidiaries are prepared in the currency of the primary economic environment in 
which it operates (its functional currency). 
 
The financial statements of Hemogenyx Pharmaceuticals LLC, Immugenyx LLC and Hemogenyx-
Cell SPRL have been translated into Pound Sterling in accordance with IAS 21 The Effects of 
Changes in Foreign Exchange Rates. This standard requires that assets and liabilities be translated 
using the exchange rate at period end, and income, expenses and cash flow items are translated using 
the rate that approximates the exchange rates at the dates of the transactions (i.e. the average rate for 
the period). The foreign exchange differences on translation of Hemogenyx Pharmaceuticals LLC, 
Immugenyx LLC and Hemogenyx-Cell SPRL are recognised in other comprehensive income (loss). 
 
Foreign currency transactions 
Foreign currency transactions are translated into the functional currency using the exchange rates 
prevailing on the dates of the transactions. Foreign exchange gains and losses resulting from the 
settlement of such transactions and from the translation at period-end exchange rates of monetary 
assets and liabilities denominated in foreign currencies are recognised in profit and loss. 
 
Share capital 
 
Ordinary Shares are classified as equity. Equity instruments issued by the Hemogenyx 
Pharmaceuticals Group are recorded at the proceeds received, net of direct issue costs. 
 
Cash 
 
Cash consists of cash bank deposit balances. 
 
Share-based payments 
 
The Group has applied the requirements of IFRS 2 Share-based Payment for all grants of equity 
instruments. 
 
The Group issues equity-settled share-based payments to the directors, senior management and 
employees (“Employee Share Options”), to corporate finance advisers for assistance in raising 
private equity, and to its Scientific Advisory Board members (“Non-employee Share Options”). In 
2021, the Group adopted the “Hemogenyx Pharmaceuticals plc 2021 Equity Incentive Plan with 
Non-Employee Sub-Plan” (the “EIP”) for the grant of options, restricted shares, and restricted share 
units to employees, directors and consultants of the Company and its subsidiaries over ordinary 
shares in the capital of the Company, which was approved by the Company’s shareholders at the 
2022 AGM. Equity-settled share-based payments are measured at fair value at the date of grant for 
Employee Share Options and the date of service for Non-employee Share Options. The fair value 
determined at the grant date or service date, as applicable, of the equity-settled share-based payments 
is expensed, with a corresponding credit to equity, on a straight-line basis over the vesting period, 
based on the Group’s estimate of shares that will eventually vest. At each subsequent reporting date, 
the Group calculates the estimated cumulative charge for each award having regard to any change in 
the number of options that are expected to vest and the expired portion of the vesting period. The 
change in this cumulative charge since the last reporting date is expensed with a corresponding credit 
being made to equity. Once an option vests, no further adjustment is made to the aggregate amount 
expensed. 
 
The fair value is calculated using the Black Scholes method for both Employee and Non-employee 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
57 
Share Options as management views the Black Scholes method as providing the most reliable 
measure of valuation. The expected life used in the model has been adjusted, based on management’s 
best estimate, for the effects of non-transferability exercise restrictions and behavioural 
considerations. The market price used in the model is the issue price of Company shares at the last 
placement of shares immediately preceding the calculation date. The fair values calculated are 
inherently subjective and uncertain due to the assumptions made and the limitation of the calculations 
used. 
 
Taxation 
 
Current tax 
 
Current taxation is based on the results for the year as adjusted for items that are non-assessable or 
disallowed. It is calculated using rates that have been enacted, or substantially enacted, by the balance 
sheet date. Current income tax assets and liabilities are measured at the amount expected to be 
recovered from or paid to the relevant taxation authorities. 
 
Deferred tax 
 
Deferred income tax is recognised on all temporary differences arising between the tax bases of assets 
and liabilities and their carrying amounts in the financial statements, with the following exceptions: 
§ where the temporary difference arises from the initial recognition of goodwill or of an 
asset or liability in a transaction that is not a business combination and, at the time of the 
transaction, affects neither accounting nor taxable profit or loss; 
§ in respect of taxable temporary differences associated with investment in subsidiaries, 
associates and joint ventures, where the timing of the reversal of the temporary 
differences can be controlled, and it is probable that the temporary differences will not 
reverse in the foreseeable future; and 
§ deferred income tax assets are recognised only to the extent that it is probable that taxable 
profit will be available against which the deductible temporary differences, carried 
forward tax credits or tax losses can be utilised. 
 
Deferred income tax assets and liabilities are measured on an undiscounted basis at the tax rates that 
are expected to apply when the related asset is realised or liability is settled, based on tax rates and 
laws enacted or substantively enacted at the statement of financial position date. 
 
The carrying amount of deferred income tax assets is reviewed at each statement of financial position 
date. Deferred income tax assets and liabilities are offset, only if a legally enforcement right exists 
to set off current tax assets against current tax liabilities, the deferred income taxes related to the 
same taxation authority and that authority permits the Company to make a single net payment. 
 
Income tax is charged or credited directly to equity if it relates to items that are credited or charged to 
equity. Otherwise, income tax is recognised in the statement of comprehensive income. 
 
Financial Assets and Liabilities 
 
Financial assets and liabilities are recognised in the Company’s statement of financial position when 
the Company becomes a party to the contractual provisions of the instrument. The Company 
currently does not use derivative financial instruments to manage or hedge financial exposures or 
liabilities. 
 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
58 
Loans and receivables are non-derivative financial assets with fixed or determinable payments that 
are not quoted in an active market. They are included in current assets, except for maturities greater 
than 12 months after the end of the reporting period. These are classified as non-current assets. The 
Company’s loans and receivables comprise Trade and Other Receivables and Cash and Cash 
Equivalents in the Statement of Financial Position. 
 
Impairment of Financial Assets 
 
The Company and Group assess at each reporting date whether a financial asset is impaired and will 
recognise the impairment loss immediately through the consolidated statement of comprehensive 
loss. 
 
Interest Bearing Loans and Borrowings 
 
Borrowings are initially recognised at the fair value of consideration received less directly 
attributable transaction costs. After initial recognition, borrowings are subsequently measured at 
amortised cost using the effective interest rate method. Where borrowings are provided by 
shareholders at an interest rate discounted to market rates, the difference on initial fair value is taken 
to equity as a capital contribution. 
 
Where the Group has entered into a hybrid instrument whereby there is a debt instrument and an 
embedded derivative financial liability, the fair value of the debt instrument less the fair value of the 
derivative financial liability is equal to loan recognised on initial measurement. 
IFRS 16, Leases 
IFRS 16 requires lessees to recognise a lease liability reflecting future lease payments and a ‘right-
of-use asset’ for virtually all lease contracts. IFRS 16 includes an optional exemption for certain 
short-term leases and leases of low-value assets; however, this exemption can only be applied by 
lessees. For lessors, the accounting remains substantially unchanged. IFRS 16 provides updated 
guidance on the definition of a lease (as well as the guidance on the combination and separation of 
contracts); under IFRS 16, a contract is, or contains, a lease if the contract conveys the right to control 
the use of an identified asset for a period of time in exchange for consideration. 
The right-of-use asset and lease liability are both based on the present value of lease payments due 
over the term of the lease, with the asset being depreciated in accordance with IAS 16 Property, 
Plant and Equipment and the liability increased for the accretion of interest and reduced by lease 
payments. 
 
Segmental reporting 
 
The Group’s operations are located in New York, USA with the head office located in the United 
Kingdom. The main assets of the Group, cash and cash equivalents, are held primarily in the United 
Kingdom and the United States, while the fixed assets and right of use assets are held in the United 
States. The Board ensures that adequate amounts are transferred internally to allow all companies to 
carry out their operations on a timely basis. 
 
 
The Group currently has one reportable segment – a biotechnology company focused on the 
discovery, development and commercialisation of innovative treatments relating to blood and 
immune system disorders and viral infections.

New Accounting Standards and Interpretations issued and applied in the Financial Statements 
 
(a) New and amended standards mandatory for the first time for the financial periods beginning on 
or after 1 January 2024 
 
The International Accounting Standards Board (IASB) issued various amendments and revisions to 
International Financial Reporting Standards and IFRIC interpretations. The amendments and 
revisions were applicable for the year ended 31 December 2024 but did not result in any material 
changes to the financial statements of the Group or Company. 
 
b) New standards, amendments and interpretations in issue but not yet effective or not yet endorsed 
and not early adopted  
 
Standards, amendments and interpretations that are not yet effective and have not been early adopted

to have a material impact on future Group financial statements. 
 
 
3. Significant accounting judgements, estimates and assumptions 
 
The preparation of the financial statements in conformity with International Financial Reporting 
Standards requires the use of certain critical accounting estimates. It also requires management to 
exercise its judgement in the process of applying the Company’s accounting policies. 
 
Estimates and judgements are continually evaluated, and are based on historical experience and other 
factors, including expectations of future events that are believed to be reasonable under the 
circumstances. The estimates and assumptions that have a significant risk of causing a material 
adjustment to the carrying amounts of assets and liabilities within the next financial year are 
discussed below. 
 
The principal areas in which judgement is applied are as follows: 
 
Valuation of stock options 
 
Management uses the Black Scholes model to value the share options. The model requires use of 
assumptions regarding volatility, risk free interest rate and a calculation of the value of the option at 
the time of the grant. Please see Note 18 for details. 
 
Intangible assets impairment 
 
When there is an indicator of a significant and permanent reduction in the value of intangible assets, 
an impairment review is carried out. The impairment analysis is principally based on estimated 

Hemogenyx Pharmaceuticals plc 
Annual Report & Financial Statements for the 
Year Ended 31 December 2024 
 
 
60 
discounted future cash flows. The determination of the assumptions is subjective and requires the 
exercise of considerable judgement about the outcome of research and development activity, 
probability of technical and regulatory success, amount and timing of projected future cash flow or 
changes in market conditions. Any changes in key assumptions could materially affect whether an 
impairment exists. See Note 12 for further details. 
 
Valuation of investment in and long-term loans to subsidiaries  
 
Management has assessed the recovery profile of the Parent Company loans granted to subsidiaries 
and noted the research and development timetable would mean that repayment of the amounts loaned 
would not commence in the short to medium term and accordingly the loans were considered to be 
long-term. Management has assessed the recoverability of the loans to subsidiaries and its investment 
in subsidiaries using the same metrics and assumptions. The determination of the assumptions is 
subjective and requires the exercise of considerable judgement about the outcome of research and 
development activity, probability of technical and regulatory success, amount and timing of projected 
future cash flow or changes in market conditions. Any changes in key assumptions could materially 
affect whether an impairment exists. Several factors such as the progression of the Phase I trial of 
HG-CT-1 gives management comfort that no impairment indicators exist over both balances.  
 
4. Segment Information 
 
The Group has one reportable segment, the discovery, development, and commercialisation of 
innovative treatments relating to blood and immune system disorders and viral infections, and 
administrative functions in the United Kingdom, and therefore the segmental information is the same 
as that presented in the primary statements.

Weighted average tax rate is calculated by reference to the tax rates effective in each of the 
jurisdictions. The tax rates effective at 31 December 2024 are 25% and 28% in the UK and the USA 
respectively. 
 
The Group has accumulated tax losses arising in the UK of approximately £4,512,000 (31 December 
2023: £3,529,000) that should be available, under current legislation, to be carried forward against 
future profits. No deferred tax asset has been recognised against these losses. 
 
The Group has tax losses carried forward in the US of approximately $21,122,000 (31 December 
2023: $18,031,000) available under current rules until 2037. Of the total Federal net operating losses, 
the amounts incurred after 2017 of approximately $9,000,000 will carry forward indefinitely. No 
deferred tax asset has been recognised against these losses. Sections 382 and 383 of the US Internal 
Revenue Code, and similar state regulations, contain provisions that may limit the tax loss carried 
forward available to be used to offset income in any given year upon the occurrence of certain events, 
including changes in the ownership interests of significant stockholders. In the event of a cumulative 
change in ownership in excess of 50% over a three-year period, the amount of the NOL carry 
forwards that the Company may utilise in any one year may be limited. 
 
 
9. Earnings per share 
 
The calculation of the basic and fully diluted earnings per share is calculated by dividing the loss for 
the year from continuing operations attributable to equity owners of the Group of £5,977,640 (2023: 
£5,787,611) by the weighted average number of ordinary shares in issue during the year of 3,301,431 
(2023: 2,822,841). 
 
Dilutive loss per Ordinary Share equals basic loss per Ordinary Share as, due to the losses incurred 
in 2024 and 2023, there is no dilutive effect from the subsisting share options. See Note 18 for 
details of stock options and warrants outstanding.

12. Intangible assets 
 
On 15 January 2015, the Company entered into an Exclusive License Agreement with Cornell 
University to grant to the Company patent rights to patent PCT/US14/65469 entitled Post-Natal 
Hematopoietic Endothelial Cells and Their Isolation and Use and rights to any product or method 
deriving therefrom. The Company paid Cornell University USD $347,500 for such licence rights. 
 
In October 2021, the Company entered into a licence with Eli Lilly & Company to use a patented 
product derived from jointly-developed intellectual property in the CDX antibody for a term ending 
on the latest of (a) the twelfth (12th) anniversary of the date of First Commercial Sale of a particular 
Licensed Product in a particular country; (b) the first day on which there is not at least one Licensed 
Patent having a Valid Claim Covering the manufacture, use, or sale of such Licensed Product in 
such country; or (c) the expiration of the last-to-expire Data Exclusivity Period for such Licensed 
Product in such country. The Company paid £181,743 or $250,000 as an up-front payment and will 
make milestone payments of up to $1 million through to Phase II clinical trials. Lilly is also eligible 
to receive substantial additional milestone payments based on the achievement of prespecified 
milestones, as well as tiered single-digit royalties on sales and a percentage of any cash payments 
received in respect of any sublicence of the licensed intellectual property. Through December 31, 
2024, the Company has not incurred any development or sales-based payment obligations to the 
licensor.

The carrying value of intangible assets is reviewed for indications of impairment whenever events 
or changes in circumstances indicate that the carrying value may exceed the recoverable amount. The 
products to which they relate are not ready to be sold on the open market. When the trials are 
completed and the products attain the necessary accreditation and clearance from the regulators, the 
Group will assess the estimated useful economic life and the IP will be amortised using the straight-
line method over their estimated useful economic lives. The directors are of the view that no 
impairment is required as the test results to date have been very positive and these products are now 
being moved on towards the clinical trial phase. Accordingly, the directors continue to believe that 
the products will eventually attain the necessary accreditation and clearance from the regulators and 
so no impairment has been considered necessary. 
 
Amortisation will be charged to operating costs in the Statement of Comprehensive Income when 
the Group achieves product sales.

16. Called up share capital 
 
Capital Reorganisation 
 
The Company carried out a subdivision and reclassification of the Existing Ordinary Shares by 1:2 
so that each Existing Ordinary Share was subdivided and reclassified into 1 new ordinary share of 
£0.000025 each (the New Ordinary Shares) and 1 deferred share of £0.009975 each (the Deferred 
Shares) (the Subdivision), followed by a consolidation of the New Ordinary Shares by 400:1  so that 
every 400 New Ordinary Shares will be consolidated into 1 New Ordinary Share of £0.01 each (the 
Consolidation, together with the Subdivision, the Capital Reorganisation).  
 
The Deferred Shares will have no right to vote or participate in the capital of the Company (save as 
set out under the ‘New Articles’) and the Company will not issue any certificates or credit CREST 
accounts in respect of them. The Deferred Shares will not be admitted to trading on any exchange. 
The rights of the New Ordinary Shares and the Deferred Shares will be set out in the New Articles 
proposed to be adopted by the Company. The purpose of the Capital Reorganisation is to reduce the 
nominal value of the Existing Ordinary Shares and to reduce the number of shares in issue.

Employee Plan 
Under the Employee Plan (“EMP”) share options are granted to directors and employees at the 
complete discretion of the Company. The fair value of the options is determined by the Company at 
the date of the grant. Options granted vest in tranches on each of the following events/dates: 
(i) 
Admission to the LSE (“Admission”); 
(ii) 
On the date falling six (6) months after Admission; 
(iii) 
On the date falling twelve (12) months after Admission; and 
(iv) 
On the date falling twenty-four (24) months after Admission 
On the provision that the option holder remains an employee of the Group. 
Options granted to most other option holders from 4 January 2018 onwards vest in equal tranches of 
12.5% every three months from the date of grant, until fully vested. 
The fair value of the options is determined using the Black Scholes method as stated in Note 2. The 
contractual life of each option granted is between two and five years. There are no cash settlement 
alternatives. 
Options are settled when the Company receives a notice of exercise and cash proceeds from the 
option holder equal to the aggregate exercise price of the options being exercised. 
 
As part of the EMP, certain share options have been granted to a Director of the Company which 
contain vesting conditions that are contingent on the authorisation of the FDA to commence clinical 
trials.   
 
Non-Employee Plan 
Under the Non-Employee Plan (“NEMP”) share options are granted to non-employees at the 
complete discretion of the Company. The exercise price of the options is determined by the Company 
at the date of the grant. The options vest at the date of the grant. 
The fair value of the options is determined using the Black Scholes method as stated in Note 2 and 
not the value of services provided as this is deemed the most appropriate method of valuation. In all 
cases non-employee option holders received cash remuneration in consideration for services 
rendered in accordance with agreed letters of engagement. The contractual life of each option granted 
ranges from two to five years. There are no cash settlement alternatives. Volatility was determined 
by calculating the volatility for three similar listed companies and applying the average of the four 
volatilities calculated. 
Options are settled when the Company receives a notice of exercise and cash proceeds from the 
option holder equal to the aggregate exercise price of the options being exercised. 
 
2021 Equity Incentive Plan with Non-Employee Sub-Plan 
Under the 2021 Equity Incentive Plan with Non-Employee Sub-Plan” (the “EIP”) share options, 
restricted shares, and restricted share units may be granted to employees, directors and consultants 
of the Company and its subsidiaries at the discretion of the Company in an aggregate amount up to 
188 shares. This was increased to 563 shares in April 2023. The fair value of awards made under 
this plan is determined in the same way as for the EMP and NEMP described above. 
 
A schedule of options granted since inception for all plans is below:

In October 2022, the expiration date of options to acquire 12,016 ordinary shares (which were 
scheduled to expire in October 2022) was extended by two years by the Board of Directors of the 
Company. The Company recognised this transaction as a modification of a share-based instrument 
for financial reporting purposes. The change in the fair value of the stock option before and after the 
modification amounted to approximately $5,400, which was recorded as part of expense related to 
share-based payment transactions. The fair value was determined using the Black Scholes model 
using the assumptions noted below.

c) 
Market risk 
 
Interest rate risk 
 
Interest rate risk is the risk that the value of financial instruments will fluctuate due to changes in 
market interest rates. The Group's income and operating cash flows are substantially independent of 
changes in market interest rates as the Group has no significant interest-bearing assets. The 
borrowings issued at fixed rates expose the Group to fair value interest rate risk. The Company's 
management monitors the interest rate fluctuations on a continuous basis and acts accordingly. 
 
The Company has floating rate financial assets in the form of deposit accounts with major banking 
institutions; however, it is not currently subjected to any other interest rate risk. 
 
Based on cash balances as above as at the statement of financial position date, a rise in interest rates 
of 1% would not have a material impact on the profit and loss of the Company and such is not 
disclosed. 
 
In relation to sensitivity analysis, there was no material difference to disclosures made on financial 
assets and liabilities. 
 
At the reporting date the interest rate profile of interest-bearing financial instruments was:

Foreign currency risk 
 
The Group operates internationally and has monetary assets and liabilities in currencies other than 
the functional currency of the operating company involved. 
 
The Group seeks to manage its exposure to this risk by ensuring that where possible, the majority of 
expenditure and cash of individual subsidiaries within the Group are denominated in the same 
currency as the functional currency of that subsidiary. 
 
The Group has not entered into any derivative instruments to manage foreign exchange fluctuations.

Capital risk management 
 
The Group defines capital as the total equity of the Company. The Group’s objectives when 
managing capital are to safeguard the Group’s ability to continue as a going concern in order to 
provide returns for shareholders and benefits for other stakeholders and to maintain an optimal capital 
structure to reduce the cost of capital. 
 
In order to maintain or adjust the capital structure, the Group may adjust the amount of dividends paid 
to shareholders, return capital to shareholders, issue new shares or sell assets to reduce debt. 
 
Fair value of financial assets and liabilities 
 
There are no material differences between the fair value of the Group’s financial assets and liabilities 
and their carrying values in the financial statements. 
 
 
23. Commitments 
Licences 
Milestone and royalty payments that may become due under licence agreements are dependent on, 
among other factors, clinical trials, regulatory approvals and ultimately the successful development 
of new drugs, the outcomes and timings of which are uncertain. 
For the licence from Cornell University to the patent of the Hu-PHEC technology, the Group’s 
minimum future payments contingent upon meeting certain development, regulatory and 
commercialisation milestones total £855,301 ($1,035,000) plus £413,189 ($500,000) on receipt of 
marketing approval from each additional market excluding the United States of America and the

European Union. Upon commencement of commercial production, the Group will pay a royalty 
between 2 to 5% on all net sales. Through 31 December 2024, none of the requirements to make 
such payments have been met. In addition, the Group pays an annual licence maintenance fee of up 
to £61,978 ($75,000) until commercial sales are achieved. 
For the licence to Eli Lilly and Company’s (“Lilly”) contributions to the intellectual property in the 
CDX bispecific antibody, future payments will be contingent upon meeting certain similar 
development, regulatory and commercialisation milestones and so do not meet the definition of 
commitments pending further developments. This licence is subject to an up-front payment to Lilly 
of $250,000 and milestone payments of up to $1 million through to Phase II clinical trials. Lilly is 
also eligible to receive substantial additional milestone payments based on the achievement of 
prespecified milestones, as well as tiered single-digit royalties on sales. In addition, the Company 
will pay Lilly a percentage of any cash payments received in respect of any sublicence of the licensed 
intellectual property. 
Leases 
In August 2021, Hemogenyx LLC entered into a lease for a 9,357 square foot purpose-built 
laboratory for eight years beginning on 1 April 2022. The lease contains escalating monthly payments 
ranging from approximately $64,300 to $76,500 per month over the lease term. The Group paid a 
security deposit of £156,114 ($188,005) during the year ended 31 December 2021 for such facility 
lease. 
Service agreements

Research Cell Banks (RCBs) for production of the Company’s proprietary recombinant protein(s) 
encoded by cDNAs. From 31 December 2021 through 31 December 2022, Hemogenyx 
Pharmaceuticals LLC has paid £199.956 (CHF 214,063) under this agreement. Under the terms of 
the agreement, Hemogenyx Pharmaceuticals LLC may pay up to CHF 590,000 at its discretion in 
aggregate, inclusive of the amounts already paid. 
In December 2021, Hemogenyx Pharmaceuticals LLC entered into service agreements with another 
party to produce components of the Company’s CAR-T product candidate. Under the terms of the 
agreement, Hemogenyx Pharmaceuticals LLC must pay an aggregate of £1,970,911 ($2,109,957) in 
milestone payments during the term of production. From 31 December 2021 through 31 December 
2024, Hemogenyx Pharmaceuticals LLC has paid £2,244,287 ($2,868,121) under these agreements. 
In September 2023, Hemogenyx Pharmaceuticals entered into a Master Services and Contract 
Agreement for a third party to provide clinical services and technologies for the forthcoming Phase 
I clinical trials for an initial term of 38 months, paying an aggregate of £1,979,753 ($2,530,057). 
This includes an upfront payment of £772,097 ($986,713) and monthly instalments over 38 months 
of £32,639 ($41,712) commencing in April 2024. From April 2024 through 31 December 2024,

24. Ultimate controlling party 
 
The Directors have determined that there is no controlling party as no individual shareholder holds a 
controlling interest in the Company. 
 
 
25. Prior period error: lease liability classification (IFRS 16) 
 
During the year ended 31 December 2024, the Group identified a classification error in the 
presentation of lease liabilities under IFRS 16 Leases in the prior year’s consolidated financial 
statements. While the total lease liability was correctly recognised, an amount of £89,438 that should 
have been presented as a current liability as at 31 December 2023 was incorrectly classified as non-
current. 
 
As a result, the comparative amounts in the consolidated statement of financial position have been 
restated to reflect the correct classification. The impact of this restatement as at 31 December 2023 
is as follows: current lease liabilities increased by £89,438 from £273,084 to £362,522, and non-
current lease liabilities decreased by £89,438 from £2,672,802 to £2,583,364. There was no impact 
on total lease liabilities, net assets, or the consolidated statement of profit or loss and other 
comprehensive income, including basic and diluted earnings per share, for the year ended 31 
December 2023. 
 
There was also no impact on the statement of financial position as at 1 January 2023, as the error 
arose during the year ended 31 December 2023. Accordingly, no restatement was required at the 
beginning of the earliest comparative period. 
 
 
26. Subsequent events 
 
In January 2025 the Company raised £340,000 through the issue of 100,000 new ordinary shares at 
a price of 340p per share. One institutional investor was also granted 50,000 warrants exercisable at 
a price of 500p each for a period of 12 months from 1 March 2025. 
 
In February 2025 the Company raised £285,000 through the issue of convertible loan notes (“CLNs”) 
and the loan note holders also received a one-for-one warrant, exercisable at a price of £4.00 per 
share for each share held upon the CLN conversion date. The CLNs converted into 95,000 ordinary 
shares on 13 March 2025.  
 
In February 2025, the Company terminated its Exclusive License Agreement with Cornell 
University.  
 
In March 2025 the Company raised £709,200 through the issue of 394,000 new ordinary shares at a 
price of 180p per share. The investor was also granted a one-for-two warrant, exercisable at a price 
of £3.50 per share for each share subscribed
