The period was a vital one in the progression of the Company. Development work on our lead HEMO-CAR-T product candidate was completed and we were able to submit an Investigational New Drug (“IND”) application to the Food and Drug Administration (“FDA”) to enable us to move into clinical trials for HEMO-CAR- T. Unfortunately, the FDA decided that certain aspects of the data initially provided did not meet its rigorous safety standards, so it imposed a clinical hold pending further development of the product. We worked hard in the final months of the year to meet the FDA’s additional requirements and, as a result, the clinical hold was lifted in January 2024. Hemogenyx Pharmaceuticals is thereby established as a “clinical stage” company and we are now proceeding to the next step in the development of HEMO- CAR-T, the commencement of Phase I clinical trials. At the same time, we continued to move forward, insofar as funding would allow, with our other main pipeline assets, our Chimeric Bait Receptor (“CBR”) platform and our CDX bi-specific CD3-FLT3 antibody (“CDX”). Significant progress was made on the former, as will be described more fully below. Fundraising We raised capital on a number of occasions in the period under review. In January 2023, we were successful in raising £4,056,250 in new equity capital at 2.5p per share which was intended to take us through the IND process and to the stage of clinical trials for HEMO-CAR-T. The clinical hold delayed matters for some months and of course diminished our cash resources. In December 2023, we therefore raised a further £534,375 at 2.375p per share to take us to the next key stage. In September, Prevail Partners LLC (“Prevail Partners”) made a strategic investment of $830,000 (£680,000) through a subscription for 11,066,067 new ordinary shares in the Company at a price of $0.075 (about 6p), at a premium of approximately 240% to the then share price. Prevail Partners is the investment partner of Prevail Infoworks Inc. (“Infoworks”), a contract research organisation that we have engaged to provide a variety of services necessary for the implementation and management of the clinical trials of HEMO-CAR-T. The price at which Prevail Partners made its investment in Hemogenyx Pharmaceuticals demonstrated its confidence in our HEMO-CAR-T product candidate. Further information on our association with Prevail Partners and Infoworks is described in the section headed “HEMO-CAR-T” below. Since the period end, and following the lifting of the clinical hold, we raised a further £3.325 million at 2p per share to enable us to move to clinical trials. While we accept that recent market conditions have been very difficult, we have been disappointed by the successively lower price at which we have had to carry out our fundraisings in the UK market, in the light of the progress we have made and the view taken by Prevail Partners concerning our status. The capital recently raised will undoubtedly take us materially further forward and we are now looking at a number of strategies for the future development of all three of our current product candidates. 3 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 Results for the Period The Group incurred a loss for the year to 31 December 2023 of £6,696,493 (31 December 2022: £3,986,982 loss). In the year to 31 December 2023 the loss mainly arose from operational expenses pursuing the Group’s objectives listed in the Strategic Report on page 10, 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, as further detailed in the Fundraising section above. HEMO-CAR-T The principal objective of HEMO-CAR-T is, as shareholders will know, to provide a new and more effective treatment and potential cure for relapsed and/or refractory acute myeloid leukaemia (“R/R AML”). AML is the most common type of acute leukaemia in adults and has poor survival rates; it is currently treated using chemotherapy, rather than the potentially more benign and effective form of cell therapy being developed by Hemogenyx Pharmaceuticals. The successful development of a new therapy for AML would have a major impact on treatment and survival rates for the disease. Development work on HEMO-CAR-T was largely completed during 2022 and work in 2023 was mainly devoted to preparing the IND application to the FDA, an essential step before being able to commence clinical trials. The FDA’s concern, as shareholders will be aware, is primarily with the safety of a treatment, and it rightly works to a very high standard. The work in preparing the IND application was extremely detailed and resulted in an application document running to over 3,000 pages. It was finally submitted in May 2023. As mentioned above, the FDA was not satisfied with a particular aspect of the detail provided and therefore imposed a clinical hold on the HEMO-CAR-T programme in June. Our scientific team worked on resolving the matter through the latter part of the year and on remanufacturing of the CAR-T components. This resulted in the clinical hold being lifted in January 2024. Although this was a setback, it is important to say that the FDA’s concerns were limited to one issue, and we were able to satisfy them much more quickly than many other companies whose prospective treatments were put on clinical hold. The removal of the clinical hold has enabled us to proceed with taking HEMO-CAR-T into clinical trials with the objective of getting an initial patient injected in the coming months. The Company has been actively putting the necessary pieces in place for some time, including discussions with the Hospital of the University of Pennsylvania, one of the leading cancer treatment hospitals in the US, in order to initiate the clinical trials process. Also, crucially, in September 2023, Hemogenyx Pharmaceuticals contracted with Infoworks, a well- established and experienced contract research organisation (“CRO”), through a Master Services and Contract Agreement for Infoworks to provide clinical services and technologies for the forthcoming Phase I clinical trials over an initial term of 40 months. An initial work plan was agreed, including clinical site coordination, project management, data management, clinical monitoring, and pharmacovigilance (safety management) services, with the use of InfoWorks’ integrated real-time data analytics platform for clinical support and real-time analysis. This vital link brings us Infoworks’ operational expertise and will ensure smooth execution of the clinical trials and fast, reliable data to lower our clinical risk and speed up our regulatory timeline. 4 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 At the same time, Prevail Partners, the investing affiliate of Infoworks, made the investment at a premium in the Company described more fully in the section headed “Fundraising” above. Chimeric Bait Receptor While our Chimeric Bait Receptor (“CBR”) was initially envisaged as a potential cure for a very wide range of viral diseases, it has recently become clear that it is also potentially a viable approach for the treatment of a range of cancers. The development of CBR as a cure for viral infections continues, and we remain excited about that, but its potential efficacy against cancer may provide a quicker route to successful development, approval and use. While we have had limited resources to apply to the development of our proprietary CBR technology platform, there have been a number of key developments and discoveries during the period under review and in the early part of 2024. We have been able to achieve as much as we have done because development of novel CBR constructs is facilitated and accelerated by in silico simulations using Artificial Intelligence (“AI”) tools and pipelines. In the wake of the COVID-19 pandemic, and in the face of global threats of emerging as well as engineered biological threats, the need for a nimble and proactive solution against future infectious agents became clear. We developed CBR as a novel, highly innovative, and patented immunotherapy initially for COVID-19. However, CBR has been designed to prevent and defeat infection by any known or emerging virus, potentially subverting the next global pandemic, and rendering virally- engineered bioweapons ineffective. To achieve proof of concept, we successfully designed a CBR construct (“CBR-COVID19”) to programme macrophages to neutralise the SARS-CoV-2 virus. We have also demonstrated that CBR-COVID19 is insensitive to several known variants of SARS-CoV-2 that make the original SARS-CoV-2 virus more infectious and challenge existing vaccine approaches. We are testing the efficacy of CBR-COVID19 against live infectious replicating SARS-CoV-2 virus in a major Biosafety Level 3 facility. One of the ultimate threats from emerging viruses, whether natural or man-made, is their uncertainty and unpredictability. Current therapeutic responses require extensive knowledge of the agent(s) as well as time-consuming and duplicative research efforts to develop effective treatments after an outbreak has begun. In this light, our first-in-class CBR platform allows for minimal lead time between first infection or pre-emptive intelligence and first response, providing protection for those on the front line of such a threat at a scale that has thus far not been achieved. As we announced in February 2024, CBR in relation to viruses is innovative in three ways: it will be an off-the-shelf therapeutic against airborne viral infections, it will be effective against emerging mutations of the targeted viruses, and it will be able to be stored, deployed and administered in the field using a standard atomiser/inhaler. These innovative features have been tested in the laboratory, and the ability of CBR to be delivered intranasally in spray form has been tested by our scientists in vivo in small animals. This recent work on the intranasal delivery of CBR is a breakthrough, enabling its development as an off- the-shelf prevention and/or treatment that will be cost-effective and simple to administer, making it ideal for the protection both of the civilian population and in biodefence. Moving onto cancer-related CBR innovations, we have found that a number of difficult conditions can potentially be treated using CBR. We have established that macrophages programmed with CBR have several potential advantages compared to other existing anti-cancer therapies. Our studies suggest that they can, inter alia, penetrate solid tumours, provide a better safety profile for treatment, and potentially cross the blood-brain barrier to target brain cancers and/or certain neurodegenerative diseases. 5 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 As announced last November, we have now demonstrated that CBR could be used effectively in the treatment of a number of cancer conditions, in particular that CBR-programmed macrophages show promise for treatment of Non-Hodgkin Lymphoma (“NHL”). Our scientists have demonstrated that human macrophages, a type of immune cells, programmed with a purpose designed CBR, are able to eliminate NHL-derived cells with high efficiency in vitro. This result suggests that the Company may be able to develop an efficient treatment for people suffering from relapsed and/or refractory stage III/IV metastasized NHL. Our work also suggests that such CBRs can also be adapted to target several solid tumours such as epithelial ovarian cancer. NHL is the eleventh most common cancer in humans, with a poor rate of recovery and cure from present treatments. There are currently an estimated 540,000 new cases diagnosed globally with an estimated 260,000 deaths per year. The successful development of a new CBR-related therapy for NHL could have a major impact on treatment and survival rates for the disease. Our work further suggests that such CBRs can be adapted to target several solid tumours such as epithelial ovarian cancer. We have also begun to see evidence that a CBR-based approach may also potentially be effective against certain neurodegenerative diseases, some of which are currently very difficult or impossible to treat, including possibly Alzheimer’s disease. In this regard, in February 2024 we announced a further significant development for CBR, this time in relation to brain cancers and potentially to neurodegenerative diseases. We have established that CBR can be delivered into the brain via programmed microglial cells. Delivery of therapeutics across the blood-brain barrier is one of the most difficult problems in the treatment of brain diseases. Our scientists have developed a means of transplanting human blood stem cells (“HSC”) that allows their engraftment and differentiation into immune cells that reside in the brain, carrying out their work in vivo in the brains of immune- compromised mice. We believe that HSCs genetically modified to make CBR and transplanted back into a patient would give rise to microglial cells which could potentially find and destroy brain cancer cells. Meanwhile, we continue to look to our patent position and, in September 2023, our patent application for CBR with the World Intellectual Property Organization was published, though it remains to be approved. In summary, we should say that the considerable potential breadth and versatility of CBR has become increasingly evident over the past fifteen months, and evidence of its practical viability has been considerably established. It is not too much to say that CBR, which we always considered to have great potential, can now be seen as possibly revolutionary, now that its widespread probable applicability to difficult or presently untreatable conditions is being established in multiple preclinical studies. CDX bi-specific antibody CDX remains an important part of the Company’s product candidate portfolio, although it remains to a certain extent in abeyance while we push on with HEMO-CAR-T. However, some steps have been taken with CDX, including approval of the patent application in the USA entitled “Method of Eliminating Hematopoietic Stem Cells/Hematopoietic Progenitors (HSC/HP) in a Patient Using Bi-specific Antibodies” as patent No. 11,945,866. This is a significant addition to the patent protection for CDX, which remains one of our key product candidates for the future. It also solidifies the Company’s position as a leader in the area of conditioning of patients for bone marrow transplants. 6 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 Conclusion It remains for me to thank the Board and our strong, highly committed group of scientists for their hard and effective work, and to look forward to another successful year in the future development of Hemogenyx Pharmaceuticals in this new phase as a clinical-stage company. Prof Sir Marc Feldmann AC, FRS MB BS, PhD, FRCP, FRCPath, FAA, F Med Sci Chairman 24 April 2024 7 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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.

He also 8 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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. Ms Sandler is the General Counsel of The Frick Collection.

Prior to that, she worked as the director of business and legal affairs for a major media and entertainment company, and in private practice for several prominent law firms. Ms Sandler received her AB from Harvard University and her JD from the UCLA School of Law and is a member of the State Bar of New York and the State Bar of California. Peter Redmond – Non-Executive Director – appointed 4 October 2017 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 URA Holdings plc, of which he remains a director. 9 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 2023. Introduction This Strategic Report comprises a number of 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, certain cancers and of 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 leukaemia-type cancers and autoimmune diseases, with the treatment of viral infections and certain non-blood cancer conditions, and with bone marrow – or hematopoietic stem cell – conditioning preparatory to 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 2023 of £6,696,493 (31 December 2022: £3,986,982 loss). In the year to 31 December 2023 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. 10 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 Cash flow and cash position Cash used in operations totalled £6,105,570 (31 December 2022: £2,910,604). As at 31 December 2023, the Group had a cash balance of £1,247,601 (31 December 2022 - £2,532,758). 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 £5,254,000 (before expenses). As at 31 December 2023 the cash position was £1,247,601 (31 December 2022: £2,532,758). 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 23, in February 2024 the Company successfully raised £3,325,000 (before expenses) to progress its recently- approved clinical trials. Intellectual property The Group is focused on developing new conditioning treatments, drugs and cell therapy products for blood and autoimmune diseases, HSC/BM transplantation, certain cancers and 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 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 11 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 leukaemias, such as acute myeloid leukaemia (“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. HEMO-CAR-T 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 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 12 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 other cancers and conditions and for the transformation of bone marrow and blood stem cell transplant procedures. HEMO-CAR-T 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 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. 13 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 The Group’s lead product, HEMO-CAR-T, is at the stage of commencing 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 HEMO-CAR-T’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 R/R acute myeloid leukaemia (“AML”) in patients who qualify for bone marrow transplantation. 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. Diversity Hemogenyx Pharmaceuticals is committed to workplace diversity which includes but is not limited to gender, age, ethnicity and cultural background. Hemogenyx Pharmaceuticals’ Diversity Policy defines initiatives which assist the Company in maintaining and improving the diversity of its workforce.

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. The table below shows our current progress against the TCFD recommendations. 15 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 TCFD Pillar Governance Recommended Disclosure Hemogenyx Pharmaceuticals Summary • 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 the Board recognises its responsibility to protect the environment (particularly as the business scales up). impact.

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 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. 17 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 into 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. The monies raised in Placings and Subscriptions support those preclinical 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 (which have yet to be designed), 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 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. 18 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 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. 19 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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. Approved by the Board on 24 April 2024 Dr Vladislav Sandler CEO 20 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 Directors’ Report for the year ended 31 December 2023 The Directors present their report with the audited financial statements of the Group for the year ended 31 December 2023. 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 leading to change technologies aim 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, with bone marrow, or hematopoietic stem cell, transplants, and with viral infections. The Company's in which bone marrow/hematopoietic stem cell ("BM"/"HSC") transplants are performed and improve their efficacy. Hemogenyx Pharmaceuticals’ distinct and complementary products include immunotherapy product candidates for the treatment of AML and other blood malignancies and patient conditioning (the CDX bi-specific antibody and CAR-T therapy), and a cell therapy product for BM/HSC transplantation (the Hu-PHEC). Each of these products holds the potential to revolutionise the way BM/HSC transplants are being performed or 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 way 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.

The net proceeds from the Placing will be used to allow the Company to progress HEMO-CAR-T to Phase I clinical trials. Further details of the Group’s future developments and events subsequent to the year end are set out in the Chairman’s Statement and Directors’ Strategic Report on pages 3 and 10 respectively. Corporate Governance 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. The Directors therefore 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. 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 (2022: £nil). Charitable Donations There were no charitable donations made by the Group in the current or prior year. 23 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 Greenhouse gas emissions The Company used less than 40,000kWh of energy in the United Kingdom during 2023 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. Auditors The auditors, PKF Littlejohn LLP, have expressed their willingness to continue in office and a resolution to reappoint them will be proposed at the Annual General Meeting. 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 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: 24 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 • • 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. Approved by the Board on 24 April 2024 Dr Vladislav Sandler CEO 25 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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://frc.org.uk/our-work/publications/Corporate-Governance. 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 2023 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 2023. 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 26 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 nine years. The role of external auditor last went to tender in 2015. The Audit Committee closely monitors the level of audit and non-audit services that it provides to the Company and Group. Having assessed the performance, objectivity and independence of the auditor, the Committee will be recommending the reappointment of PKF Littlejohn LLP as auditor to the Company at the 2024 Annual General Meeting. During the year to 31 December 2023 the Audit Committee considered the following key issues in relation to the Financial Statements: Issue • Accounting policies • Carrying value of investment in Hemogenyx Pharmaceuticals LLC • Carrying value of licensed intangible assets • Going concern review • Review of audit and non-audit services and fees Action the significant reviewed and discussed The Committee accounting policies with management and the external auditor and reached the conclusion that each policy was appropriate to the Group. 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 2023. 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 2023. 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. 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. 27 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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: 28 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 • 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. Attendance at Board meetings Dr Vladislav Sandler Professor Sir Marc Feldmann Alexis Sandler Peter Redmond Number held and entitled to attend 12 12 12 12 Number attended 12 4 11 12 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 is Ben Harber. He is 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. 29 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 30 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 2023 include: • Attended the 2023 AGM 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. 31 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 10 of this report. Dr Vladislav Sandler CEO 32 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 33 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 ▪ ▪ ▪ ▪ 33 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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. ▪ ▪ Members The Remuneration Committee comprises the following independent Non-Executive Directors: Name Peter Redmond Alexis Sandler Remuneration Components Position Chairman Member Date of appointment 5 October 2017 5 October 2017 The Company remunerates directors in line with best market practice in the industry in which it operates. 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 $275,000 in 2022 which rose to $324,000 in March 2023 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 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 work in connection with Immugenyx’s development of its AHC. Pursuant to this contract, Dr Sandler receives $64,889 (2022: $64,889) and 10,000 ownership units in Immugenyx LLC per annum. This contract has the same noncompete and non-interference covenants in the event of its termination as his contract with Hemogenyx Pharmaceuticals LLC. 34 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 2023 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 37 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 FTSE Techmark Mediscience chosen due to sector relevance: Investment Performance Comparison 500 450 400 350 300 250 200 150 100 50 0 5 1 - v o N 6 1 - b e F 6 1 - y a M 6 1 - g u A 6 1 - v o N 7 1 - b e F 7 1 - y a M 7 1 - g u A 7 1 - v o N 8 1 - b e F 8 1 - y a M 8 1 - g u A 8 1 - v o N 9 1 - b e F 9 1 - y a M 9 1 - g u A 9 1 - v o N 0 2 - b e F 0 2 - y a M 0 2 - g u A 0 2 - v o N 1 2 - b e F 1 2 - y a M 1 2 - g u A 1 2 - v o N 2 2 - b e F 2 2 - y a M 2 2 - g u A 2 2 - v o N 3 2 - b e F 3 2 - y a M 3 2 - g u A 3 2 - v o N HEMO FTSE small cap FTSE Techmark Mediscience 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 historical investment performance is not reflective of the current Group. Consideration of shareholder views The Board considers shareholder feedback received and guidance from shareholder bodies. This feedback, plus any additional feedback received from time to time, is considered as part of the Company’s annual policy on remuneration. Approved on behalf of the Board of Directors. Peter Redmond Director & Remuneration Committee Chairman 24 April 2024 38 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 2023 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 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 to 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 2023 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 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. Conclusions relating to going concern In auditing the financial statements, we have concluded that the director’s 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 the parent company’s ability to continue to adopt the going concern basis of accounting included the procedures as noted in the Key Audit Matters section of our report. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the group’s or parent company’s ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue. In relation to the entities reporting on how they have applied the UK Corporate Governance Code, we have nothing material to add or draw attention to in relation to the directors’ statement in the financial statements about whether the director’s considered it appropriate to adopt the going concern basis of accounting. 39 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 £132,000 (2022: £115,000). This was calculated based on 2% of total expenses for the year, 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 £29,000 (2022: £10,000) 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 £92,400 (2022: £80,500) and the parent company was set at £20,300 (2022: £7,000), being 70% of materiality for the financial statements as a whole respectively. A benchmark of 70% for performance materiality 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 £6,600 (2022: £5,750) for the group financial statements and £1,450 (2022: £500) 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. 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 a significant component, being Hemogenyx Pharmaceuticals LLC, was 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 than 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 40 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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. Key Audit Matter How our scope addressed this matter Carrying value of investments in, and loans to, subsidiary undertakings (Parent company – Note 2, Note 13 and Note 14 ) Investments held by the parent company in subsidiaries, as at 31 December 2023, totalled £8.0m in the Company Statement of Financial Position. Loans to those subsidiaries, as at 31 December 2023, are reported as £18.1m. If the These are significant balances due to the subsidiary parent company. 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’s financial performance and to corroborate the directors’ evaluation of recoverability; development progress • Reviewed and assessed the current state of development, and scientific the and commercial progress of products under development; • Reviewed board minutes for any indications of changes in investments held by the parent company; • Agreed ownership documents of all the subsidiaries in the group; and • Reviewed the market capitalisation of the group to provide further assurance of the the carrying value of 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. Going concern company – Note 2) (Group and parent 41 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 When preparing financial statements, those charged with governance should satisfy themselves as to whether the going concern basis is appropriate. 570 (UK) “Going the auditor concern” ISA specifically requires to conclude on; whether a material uncertainty related to going concern exists; the Directors use of the going concern assumption in the preparation of the financial the appropriateness relevant disclosures in the financial statements. the appropriateness of statements; and any of As the group and parent company are required to raise additional funds in discrete tranches on a regular basis, the is uncertain, going timing of which concern was deemed to be a key audit matter. As part of our audit, we have performed the following procedures: • Reviewed management’s assessment of going concern to 31 December 2025 and assessed the reasonableness of key assumptions and inputs used by management; • Evaluated and corroborated the key assumptions and inputs underlying the budgets and cash flow forecasts, including sensitivity analysis against the base case scenario; • Discussed with management how they intend to fund the clinical trials and other clinical programs, including an assessment of the funding options currently under negotiation; • Compared management’s forecasts to actual results through the subsequent events period and performed inquiries to the date of this report; • Assessed the probability of obtaining additional sources of funds when required, together with the ability to defer research and development expenditure; and • Assessed the disclosures made regarding going concern the financial statements for consistency with management’s assessment. in intends to progress The group its key development project to clinical trials together with the performance of other clinical programs. Significant additional funds will be required in order to progress as planned, which are not yet agreed and unconditional. As disclosed in Note 2, the group has a high proportion of discretionary expenditure which it is able to defer, if sufficient funding is not available. 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 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 42 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 company and its 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: • • adequate accounting records have not been kept, 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 23; • 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 32; • 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 55; • 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 24; 43 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 • Board’s confirmation that it has carried out a robust assessment of the emerging and principal risks set out on page 18; • The section of the annual report that describes the review of effectiveness of risk management and internal control systems set out on page 31; and • The section describing the work of the audit committee set out on page 26. Responsibilities of directors As explained more fully in the directors’ responsibilities statement, 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 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 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, 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, FCA Listing Rules, the Disclosure Guidance and Transparency Rules Sourcebook, the UK Corporate Governance Code and US Food and Drug Administration. • 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 44 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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.

This description forms part of our auditor’s report. Council’s website Other matters which we are required to address We were appointed by the audit committee on 30 June 2023 to audit the financial statements for the period ending 31 December 2023 and subsequent financial periods. Our total uninterrupted period of engagement is 9 years, covering the periods ending 31 December 2015 to 31 December 2023. The non-audit services prohibited by the FRC’s Ethical Standard were not provided to the company and we remain independent of the 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.

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 2023. 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 2023 was £1,620,638 (2022: profit of £1,202,024). 53 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 Research and development expenditure Research and development (i) 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. Clinical trial expenses (ii) 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 54 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 Leasehold improvements Property & equipment Impairment of non-financial assets 33% 12.5% 20% - 50% Straight-line Straight-line Straight-line 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. 55 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 The Company successfully raised £5.25 million (before expenses) through the allotment and issue of new ordinary shares during the year ended 31 December 2023, and a further £3.25 million in early 2024. These proceeds were raised in order to facilitate the progression of the Company's HEMO- CAR-T 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. However, 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. 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. As a result, 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 liabilities 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 liabilities are classified as current liabilities 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 liabilities. The liabilities 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 56 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 57 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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. 58 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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. 59 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 2023 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 2023 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 are as follows: Standard   IFRS 16 (Amendments) IAS 1 (Amendments) IAS 8 (Amendments) IAS 17 (Amendments) IAS 12 (Amendments) Impact on initial application Property, plant, and equipment Classification of Liabilities as Current or Non- Current. Accounting estimates Insurance Deferred Tax Effective date 1 January 2024* 1 January 2023 1 January 2023 1 January 2023 1 January 2023 * Subject to endorsement The Group is evaluating the impact of the new and amended standards above, which are not expected 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. 60 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 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. 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. The following tables present expenditure and certain asset information regarding the Group’s geographical segments for the year ended 31 December 2023 and 2022: SEGMENT ASSETS United Kingdom - Non-current - Current United States - Non-current - Current Belgium (Discontinued operation) - Non-current - Current Total - Non-current - Current CAPITAL EXPENDITURE United Kingdom United States Belgium (Discontinued operation) Year Ended 31 December 2023 £ Year Ended 31 December 2022 £ - 234,056 3,936,279 1,915,093 - 20,465 3,936,279 2,169,614 - 117,285 - 117,285 - 109,314 4,497,827 2,464,581 - 20,887 4,497,827 2,594,782 - 430,611 - 430,611 Capital expenditure consists of the purchase of property, plant and equipment.

The tax rates effective at 31 December 2023 are 25% and 28% in the UK and the USA respectively. The Group has accumulated tax losses arising in the UK of approximately £4,100,000 (31 December 2022: £3,225,000) 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 $18,031,000 (31 December 2022: $11,377,000) 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 £6,696,493 (2022: 63 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 £3,979,314) by the weighted average number of ordinary shares in issue during the year of 1,129,136,727 (2022: 979,749,321). Dilutive loss per Ordinary Share equals basic loss per Ordinary Share as, due to the losses incurred in 2023 and 2022, there is no dilutive effect from the subsisting share options.

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, 2023, the Company has not incurred any development or sales-based payment obligations to the licensor. 65 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 Cost 31 December 2021 Additions Exchange movements 31 December 2022 Additions Exchange movements 31 December 2023 Intellectual Property £ 441,493 - - 441,493 - - 441,493 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. 13.

The loans are interest free and will be repaid when Hemogenyx LLC’s operational cash flow allows. Management has undertaken an impairment assessment of the loan as at 31 December 2023 and has determined that that there was no impairment required due to continued progress of the product candidates. The interest rate and impairment assessment are reviewed on an annual basis. 66 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 14.

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) (ii) (iii) (iv) Admission to the LSE (“Admission”); On the date falling six (6) months after Admission; On the date falling twelve (12) months after Admission; and 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. 69 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 30,000,000 shares. This was increased to 90,000,000 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: Employees, including directors* Members of the Scientific Advisory Board Total Number options 104,326,986 12,481,912 116,808,898 * Details of options held by individual directors are disclosed in the Directors’ Report. In October 2022, the expiration date of options to acquire 4,806,577 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.

Financial instruments The Group’s financial instruments consist of cash, amounts receivable, accounts payable and accrued liabilities. Fair value of financial assets and liabilities Fair values have been determined for measurement and/or disclosure purposes based on the following methods. When applicable, further information about the assumptions made in determining fair values is disclosed in the notes specific to that asset or liability. The carrying amount for cash, accounts receivable, and accounts payable and accrued liabilities on the statement of financial position approximate their fair value because of the limited term of these instruments. The fair value of deferred payment approximates its fair value. The investment is carried at cost as it is not traded on an active market. Financial risk management objectives and policies The Company has exposure to the following risks from its use of financial instruments: • Credit risk • Liquidity and funding risk • Market risk The following table sets out the amortised costs categories of financial instruments held by the Company as at the year ended 31 December 2023 and year ended 31 December 2022: Group Year Ended 31 December 2023 £ Group Year Ended 31 December 2022 £ Company Year Ended 31 December 2023 £ Company Year Ended 31 December 2022 £ 5,138 1,247,601 1,252,739 9,810 2,532,758 2,542,568 - 219,236 219,236 - 88,909 88,909 (301,707) (2,945,886) (374,343) (3,422,835) (119,249) - (82,746) - (3,247,593) (3,797,178) (119,249) (82,746) Assets Trade and other receivables, except prepayments Cash and cash equivalents Liabilities Trade and other payables Lease liabilities a) Credit risk The Group had receivables of £0 owing from customers (31 December 2022: £0). All bank deposits are held with Financial Institutions with a minimum credit rating of B. 72 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 b) Liquidity and funding risk The Group regularly reviews its major funding positions to ensure that it has adequate financial resources in meeting its financial obligations. The Group takes liquidity risk into consideration when deciding its sources of funds. The principle liquidity risk facing the business is the risk of going concern which has been discussed in Note 2. 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: Group Year Ended 31 December 2023 £ Group Year Ended 31 December 2022 £ Company Year Ended 31 December 2023 £ Company Year Ended 31 December 2022 £ 1,247,601 2,532,758 219,236 88,909 Financial Assets Cash and cash equivalents 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. The following table shows a currency of net monetary assets and liabilities by functional currency of the underlying companies for the years ended 31 December 2023 and 31 December 2022: 73 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 31 December 2023 Functional Currency US Dollars Euro Currency of net monetary assets/(liabilities) Pounds Sterling US Dollars Euros Total Pound Sterling £ 206,397 12,839 - 219,236 £ - 1,007,900 - 1,007,900 31 December 2022 Functional Currency Pound Sterling £ 75,358 13,551 - 88,909 US Dollars £ - 2,422,962 - 2,422,962 Currency of net monetary assets/(liabilities) Pounds Sterling US Dollars Euros Total Capital risk management Total £ 206,397 1,020,739 20,465 1,247,601 Total £ 75,358 2,436,513 20,887 2,532,758 £ - - 20,465 20,465 Euro £ - - 20,887 20,887 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 74 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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 2023, 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 In December 2021, Hemogenyx Pharmaceuticals LLC entered into a service agreement to establish 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 2023, Hemogenyx Pharmaceuticals LLC has paid £1 ($1,134,059) 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 2,530,057. This includes an upfront payment of 986,713 and monthly instalments over 38 months of 41,712 commencing in April 2024. No sums other than an upfront fee were paid during the year ended 31 December 2023. Share options As detailed further in Note 18, certain share options contain contingent vesting conditions. 75 Hemogenyx Pharmaceuticals plc Annual Report & Financial Statements for the Year Ended 31 December 2023 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. Subsequent events In February 2024 the Company was granted a patent by the United States Patent and Trademark Office entitled Method of Eliminating Hematopoietic Stem Cells/Hematopoietic Progenitors (HSC/HP) in a Patient Using Bi-specific Antibodies. Also in February 2024, the Company was informed by the FDA that it had lifted the clinical hold on the IND application for HEMO-CAR-T for the treatment of acute myeloid leukemia. The FDA confirmed that the Company had addressed all issues identified in its prior clinical hold letter satisfactorily and consents to the Company proceeding with its Phase I clinical study of HEMO- CAR-T. The Company successfully raised US$4.2 million (£3.325 million) before expenses through the allotment and issue of 166,250,000 new ordinary shares at 2 pence per share. The funds were raised to allow the Company to progress HEMO-CAR-T to phase 1 clinical trials. 26.
