tAXIA Statement from Chair Our current Strategic Plan (www.ataxia.org.uldstrategic-plan-22-25/) aims for faster, accurate diagnosis of ataxia; improving access to specialist, integrated care (including mental health care), treatments and drugs for the ataxias; and to consistently maximise the impact of research activity leading to treatments and cures. Its final ambition is to enable people affected by ataxia to have greater access to services aimed at improving financial circumstances. Last year our Annual Report celebrated the approval in the USA of the first drug for Friedreichs ataxia, Skyclarys, which we hoped would be available quickly to people in the UK. Throughout 2023 and early 2024 we were in touch with Biogen, the pharmaceutical company which is bringing it market, encouraging them to submit Skyclarys to the UK regulators to be approved here, and made available through the NHS. We continue to work to ensure the drug becomes available to people with FA as soon as possible, hopefully joined by at least one more treatment for another ataxia. As trials of potential treatments for the ataxias multiply, we are preparing for a new era in the work of Ataxia UK: as a channel for patient vol￿S into the many drug approval processes that we hope will follow. In the meanwhile, we have partnered with others to bringing a rare ataxia from the basic, discovery, research stage to the trial of a potential treatment in 5 years. Likewise, our support services to people affected by the ataxias have entered a transformative phase following the obtaining of a 5-year grant from the National Lottery Community Fund to support the development of our Helpline and Advocacy ServI￿S in England and employ our first Specialist Ataxia Nurse to work with people affected by ataxia in January 2025, which we believe will, among other benefits, give access to quicker diagnosis. In April 2023 our Scottish Advice Service opened in partnership with Parkhead CAB in Glasgow; followed by the launch of the Advocacy seNice. These services add to the considerable support provided by the Helpline through which the financial circumstances of many Friends have been improved with the assistance of Ataxia UK. The support that Ataxia UK provides to people affected by ataxia is made possible through the generous donations and fundraising of Friends and supports and the grant giving of Trusts and foundations. The consistent financial support provided through the fundraising of our supporters, even at this difficult time, is always impressive. We are also grateful to the many committed volunteers who provide the governance of the charity as Trustees or Sub-Group members, and support our service delivery as Helpliners or as Co-ordinators of peer support groups. Many thanks to everyone who contributed to our work over the last year.

tAXIA Structure, Governance & Management Ataxia UK is a company limited by guarantee, incorporated in England and Wales on 25 November 2003, a registered charity in England and Wales {number 1102391) and a charity registered in Scotland (number SC040607). It is governed by its Memorandum and Articles of Association, adopted on 25 November 2003. Ataxia UK is managed by a Board of Trustees, which sets strategies and policies. All of the Trustees have a connection to ataxia either through having a diagnosis themselves or having friends or family with the condition. The Annual General Meeting of the charity took place on Sunday October 22nd 2023. Under the articles of association of the charity, trustees are nominated for election by the Friends of the charity, comprising beneficiaries affected by ataxia and others interested in the welfare of those affected by ataxia. Prospective Trustees have an interview with current Trustees before standing for election to be nominated by Friends. Trustees may remain in post for four years and then re-stand for a second term. New Trustees are invited to an induction session with the CEO and the Chair(s) of the Board of Trustees before their first Board Meeting. The meeting covers the Ataxia UK constitution, including the objects of the charity,. the legal duties of trustees; our Code of Conduct and Conflicts of Interest policies. Ataxia UK'S finances. the current strategic plan; aims and objectives, and the internal structure of the charity. New Trustees are provided with the Ataxia UK'S Trustee Handbook, which also includes links to the most significant documents on the Charity Commission website. Pay and remuneration is considered annually by a Remuneration Committee, comprising the Chair, Treasurer and one other Trustee. It meets during the budget setting prO￿sS to review salaries and grading levels, London weighting, incremental payments and inflation rises. The Remuneration Committee is provided with comparative benchmark information relating to similar posts in corresponding organisations to assist with their decision. Ataxia UK is a Living Wage Employer.

Ataxia UK | Annual Report- 2023- 2024 Public Benefit In compliance with the Charities Act 2011, Ataxia UK has adopted a Statement of Public Benefit as follows: "Ataxia UK is an inclusive organisation which promotes the wellbeing of all people affected by ataxia. We provide information and support services to people affected by ataxia and specialist services for this medical condition, many of which are not available from the NHS or other statutory or voluntary sources. We work to end isolation and promote engagement in social, educational and leisure activities for people affected by ataxia and their families. We educate the broad community and key subsections within it, such as the medical and social ServI￿S professions, about the effects of ataxia. We also fund vital research projects into potential treatments, aiming to find a cure for ataxia. There is currently no specific government funding for ataxia research.

tAXIA Statement of Equality, Diversity and Inclusion Ataxia UK has also adopted a Statement of Equality. Diversity and Inclusion: "Our vision at Ataxia UK is a world free of ataxia. Our mission is to find treatments and cures for the ataxias and to support everyone affected by ataxia. We will not achieve these aims alone. that's why we consider both those who work for Ataxia UK and Friends (members) we support who are affected, and partners with whom we collaborate, to be critical to our eventual success. Ataxia UK has always been committed to equality of opportunity to ensure all those who work for Ataxia UK, and those we represent, are treated equally, with dignity and respect. We ensure this by creating an environment in which individual differences, and the contributions of all, are recognised, valued, and enabled to enhance everything we do. We seek to ensure that every Ataxia UK campaign, programme and event promotes the principles of equality and diversity, and actively encourages our supporters and partners to share our standards and ambitions of fairness and inclusion. Our aim is to create an environment which is welcoming to all sections of society to enable our staff to be truly representative of our Friends and supporters. Additionally, for each employee to feel respected and able to give their best, regardless of their background and abilities. We encourage and expect the highest possible standards of work and conduct in everyone associated with Ataxia UK. and we recognise that this can only be achieved if the people that work at Ataxia UK feel valued and included. One of our core values is to ensure that everything we do has the needs of people affected by ataxia at its ￿ntre. We recognise that our Friends and supporters are people with differing needs, situations, goals and lifestyles. This is why equality and diversity are fundamental to our vision. Removing the barriers that limit aC￿sS for everyone requires embedding equality and diversity into everything we do. That way, everyone can be confident that Ataxia UK is diverse and inclusive. We are led by people affected by ataxia and ensure that the majority of our Board of Trustees is drawn from the diverse community which is affected by the condition. The Trustees confirm that they comply with their duty to have regard to the guidance on public benefit published by the Charity Commission and the

Ataxia UK | Annual Report- 2023- 2024 Office of the Scottish Charity Regulator OSCR in exercising their powers and duties. Ataxia UK operates throughout the United Kingdom of Great Britain and Northern Ireland through its network of Branches and Support Groups, which provide activities and support to Friends. The 2023 Annual National Conference was held in person. We have continued to work in partnership with other organisations with shared interests, principally Genetic Alliance UK, The Neurological Alliance, the Association of Medical Research Charities (AMRC) and Euro- ataxia. Our Chief Executive is the Secretary of Euro-ataxia, a federation of 20 patient organisations from 16 different European countries. The qft.iontifir. AAviortrv P.rtmmitt¢kts l.RAe.l is a sub-committee of the Board of Trustees and provides independent scientific advi￿ to the Board of Trustees on.. Research priorities for Ataxia UK Whether to fund specific research proposals The significance of research developments in related fields for ataxia and the development of novel research approaches The direction and scope of activity of Ataxia UK'S Research staff The quality and progress of research projects funded by the charity The best practice to review grant proposals The most appropriate mechanisms for attracting high-quality research proposals Promoting research in the field of ataxia The SAC comprises the following independent scientific members: Dr Javier Alegre-Abarretegui, Dr Franziska Denk, Professor Helen Dawes, Dr Mark Pook, Professor Keith Morris. Dr Gita Ramdharry and Dr Sophie Rowlands. The committee also included the following lay members during the year: Yanita Oparlakova, Harriet Brown and Nathan Hall. Professor Barry Hunt acted as the Ataxia UK'S Board Scientific Advisor. All members are unpaid volunteers.

tAXIA Employees During 2022-23 the average number of full-time equivalent employees during the year was 18 (with all employees, time involved in providing either support to the governance of the Charity or our charitable activities). From May 2023 our Finance Department has been supported by Fiona Bevan of Bevan Financial Management Ltd. We outsource IT support and HR advice functions. Volunteers In addition to the volunteers who function as trustees, many other volunteers play an important part in supporting Ataxia UK. During 2022-23 we have employed a number of interns and offered opportunities to volunteers throughout the charity. They have provided invaluable assistance in our day- to-day work, contributing towards our projects, such as the Ataxia Magazine. We have continued to recruit more committed volunteers. The current economic situation is hitting people with disabilities very hard. We are therefore especially grateful to those who have managed to raise funds for us, those who have donated to our appeals and regular givers, and the very generous support of people who have left bequests to Ataxia UK. We are also grateful to the volunteers who assist us by serving on the Finance Sub-committee, Scientific Advisory Committee, Medical Advisory Panel, Pharma Advisory Group, Fundraising and SeNices Services Advisory Groups. During the year five trained volunteers supported the Helpline seniice by answering phone and email enquiries. The contribution of all of our volunteers to the work of Ataxia UK is much valued and appreciated. Risk Management As in previous years, the Board actively managed the risks to the charity, focusing on the most serious. We maintain a register of risks and controls, and activities to mitigate risk throughout the year. a register the most significant risks and their mitigation will be enclosed following further internal review.

Ataxia UK | Annual Report- 2023 - 2024 Objectives & Activities Ataxia UK'S charitable objectives are to 'relieve those persons affected by ataxia,. Many different kinds of ataxia have been identified, with varying causes and characteristics. Typically, they are slowly progressive conditions in which initial clumsiness and poor balan￿ and co-ordination can lead to total physical disability. Other symptoms may include problems with speech, sight and hearing. There is currently no treatment for most ataxias, although good progress towards treatments is being made for some. One of our primary objectives is to find the causes of, and suitable treatments and cures for the various forms of ataxia. We do this by promoting and facilitating research in the ataxias, as well as funding research projects. Research grants are made on the basis of proposals from qualified researchers which have been assessed by peer reviewers and evaluated by Ataxia UK'S Scientific Advisory Committee. All projects, where appropriate, have approval from the Ethical Approval Committee local to the lead researcher. People with ataxia want a quick diagnosis that's delivered in a supportive and sympathetic manner, with the chol￿S of care explained and assistance in accessing them available, if required. They want information about their condition and medical care to enable the management of symptoms. Ataxia UK seeks to improve treatments and care by researching the experiences and requirements of people with ataxia and by developing replicable model solutions to the problems they experience. Our most significant work in this area is the development of Ataxia UK'S accredited Specialist Ataxia Centres. specialist clinics within the NHS that aim to bring together in a 'one-stop shop, all the services needed by someone with ataxia, from diagnosis to the ongoing management of their condition. In the absence of treatments and cures, Ataxia UK recognises the need to provide as many care and support services for people affected by ataxia as our resources will allow. These SeNi￿S comprise all other services for beneficiaries, including information and website services, such as our quarterly Ataxia Magazine, monthly eNewsletter, Helpline services, conferences and workshops on topics of interest, our network of Branches and Support Groups, and our Incontrol project that aims to combat loneliness and isolation within the ataxia community. Raising awareness of ataxia is a fundamental desire of people with ataxia. Ataxia UK is focussing its efforts on improving the understanding of the condition in the NHS, where diagnosis and treatment are often delayed, and 10

tAXIA also in the social care sector, where an understanding of the condition could significantly improve the situation of people affected by ataxia. Our Strategic Plan Ataxia UK'S Strategic Plan for 2022-25 contains these ambitions: Improve access to specialist, integrated care (including mental health care), treatments and drugs for the ataxias Faster, accurate diagnosis Consistently maximise the impact of research activity leading to treatments and cures Enable greater access to ServI￿S aimed at improving wellbeing and financial circumstances Our Strategic Plan 2022-25 takes into account the impact of the changes brought about in many areas of life by the Covid-19 pandemic which arrived towards the end of 2019-20, and the current economic climate which is affecting disabled people more than the general public and exacerbating the serious poverty of a small but significant number of people affected by ataxia. Some of the most significant actions we are taking to meet these objectives are: Establish a peripatetic Specialist Ataxia Nursing Service to accompany patients to appointments and support them in managing all aspects of their care. Continue to develop the Helpline and Advocacy Service and improve the support information held on the website. Revise the Medical Guidelines for the Treatment of the Ataxias and publish the 4th Edition. Increase the patient representation work we undertake in research projects. Increase the number of Accredited Ataxia Centres in the NHS to at least six. Support the drugs approval prO￿sS in the UK. Utilise the All About Ataxia seminar model to develop other online information seminars.

Ataxia UK | Annual Report- 2023 - 2024 Achievements & Performance, Aims for 2024- 2025 Research Research aims for 2023- 2024 Facilitate nebNorking amongst UK Ataxia Researchers Press for swift approvals for ataxia treatments in the UK Publication and dissemination of DRPLA research Plan next International Congress of Ataxia Research in London in Autumn 2024 Facilitate networking amongst UK based ataxia researchers Ataxia UK hosted its first networking event for UK-based researchers in September 2023. This was an in-person event in London, with almost 50 attendees, including researchers, clinicians, Ataxia UK representatives and two people living with ataxia. We invited participants to present their research on a range of ataxias, share information, reSoUr￿S and expertise to foster collaboration. The event also featured a Q&A session with people who live with ataxia, on the value of patient engagement in ataxia research. There was also an interesting discussion session at the end where we gathered ideas from the delegates on future events and activities Ataxia UK could do to facilitate research. We are exploring the possibility of setting up network for physios and one for junior researchers. It was a very successful nebNorking event, and we received very positive feedback. Press for swift approvals for ataxia treatments in the UK Towards the end of last year, we had the exciting news that the first drug was approved for people aged 16 and above with Friedreich's ataxia in the US. This was followed by approval by the EU in February 2024. The drug, Skyclarys (also known as Omaveloxolone), has been shown to slow the progression of the condition in trials, and being the first approved drug to treat FA it is a huge step forward. Following Brexit, the UK is no longer aligned with the EU drug regulatory framework, so Ataxia UK has been actively encouraging approval of the drug in the UK. First, we worked with Reata pharMa￿UtIcals, who developed Skyclarys, and then following the acquisition of Reata by Biogen in September 12

tAXIA 2023 we have been supporting and encouraging Biogen to seek UK approval, and we are hopeful this will happen soon. Ataxia UK has also written to the Secretary of State for Health to request support in getting Skyclarys made available to UK patients sooner. To drive forward the approval process in the UK, we set up an FA Special Interest Group, which includes clinical experts, Ataxia UK staff, and parents of children with FA. During the year we also engaged with consultants Realise Advocacy, who specialise in advising charities in this area. Together we drafted an Action plan and did an evidence review to identify any gaps in the information that will help with the drug approval and in the evaluation by the bodies that make recommendation on funding drugs on the national health service in the UK. NICE and Scottish Medicine Consortium. This is important so Ataxia UK can be prepared and get actively involved. Indeed, Ataxia UK and people with FA can play a critical role in this process to get Skyclarys to people with FA in the UK as soon as possible. We will do our utmost to ensure that the voices of people affected by FA are heard by the regulators, and as such Ataxia UK has been preparing to engage in the pro￿sseS at every opportunity. Ataxia UK also continues to work with other companies with FA programmes, as it is important to note that the currently approved drug is not a cure, and it is likely that a combination of different treatments will be needed in FA. In addition, the knowledge gained will have an impact when other drugs go through the same process for other ataxias. Indeed, for SCA3 we have already worked, via Euro-ataxia, in providing information on the condition for a drug that has been going through the EMA approval system. Publication and dissemination of DRPLA research We continue to update our community on the progress of the DRPLA research programme through social media and newsletters. Additionally, this year, we published three articles in scientific journals to increase visibility of our work and share our findings with the scientific and medical community. One article highlights the strides we have made in understanding DRPLA and our dedication to fostering a strong, united community of medical professionals, researchers and families. It also describes the resources scientists have developed to advance research on DRPLA and test potential treatments. Our Research Manager collaborated with neurologists to publish a review of current knowledge about DRPLA and providing recommendations for the best clinical care for people with DRPLA. CureDRPLA commissioned a company to interview people with DRPLA and their caregivers to better understand the impact of DRPLA, symptom 13

Ataxia UK | Annual Report- 2023 - 2024 progression and their preferences for future clinical trials. The main findings from these interviews have been published in a scientific journal. Plan next International Congress of Ataxia Research in London in Autumn 2024 Plans are progressing well for the next International congress for ataxia research, which will be held in London. Ataxia UK is again working jointly with the two US ataxia charities NAF and FARA; and we are joined by the Ataxia Global Initiative. We are pleased to be working together on what promises to be a great opportunity for networking and learning the latest on ataxia research with experts from around the world. The Scientific Steering Committee is working on an interesting scientific programme and there will also be input from a Trainee organising Committee who will organise specific activities to engage more junior researchers. Other Research Activities Ataxia UK Research Grants Programme During the year Ataxia UK awarded seven grants, five via our standard research programme, and two under the DRPLA programme. Including these projects there are currently 23 projects being managed. In addition, we gave travel awards and a conference sponsorship. Ataxia UK Grants 1.

Analysis of research outcomes of Ataxia UK funded research The impact of the research we fund is evaluated every year using the Researchfish online portal with very positive findings. The last 10 years, data shows that every £1 invested in research by Ataxia UK, raises an extra £4.39 in further funding used specifically for ataxia research. This illustrates the high quality of our funded research. Over the 10 years our funded research has produced 83 papers published in scientificlmedical journals and the development of 42 new research tools. Medical Research Charities Covid Support Fund For the third year running Ataxia UK secured a grant from the UK Government Covid Medical Research Charities Support Fund to support research we had funded during the year involving early career researchers in the UK. The grant of £218,585 is extremely welcome and will allow further funding of ataxia research. Being a member of the Association of Medical Research Charities (AMRC), and thus following good practice in the grant programme, meant Ataxia UK was an eligible organisation for this scheme. Update on DRPLA Research Programme Ataxia UK has been collaborating with CureDRPLA, a Us-based foundation, since March 2020 to advance research in Dentatorubral-pallidoluysian atrophy (DRPLA), a rare form of inherited ataxia. CureDRPLA provides funds to employ a Research Manager within Ataxia UK to support the Head of Research in leading the DRPLA Research Programme. The expertise we are gaining will help us advance research in other ataxias. 15

Ataxia UK | Annual Report- 2023 - 2024 Ataxia UK and CureDRPLA are coordinating the DRPLA Natural History and Biomarkers study, which is recruiting participants in the UK, US and other countries to understand how this condition progresses over time and collect clinical information that will inform future clinical trial designs. Several participants have completed the first study visit and a few have completed the year 1 follow-up visit. We also coordinate the CureDRPLA Global Patient Registry, an online collection of questionnaires to better characterise DRPLA. The registry currently holds data on 49 people with DRPLA from 10 different countries. In 2024, we aim to analyse the data from this registry to gain insights into DRPLA symptoms and progressions. We have succeeded in attracting an Msc placement student who can support our DRPLA Research Manager in analysing the registry information and publishing the findings in a scientific journal. In October 2023, CureDRPLA hosted the second DRPLA research conference in Boston (US) with 26 attendees. Including researchers from academic institutions in the US, UK, Italy and Japan attended the conference, along with representatives from three pharmaceutical companies. CureDRPLA is planning to host another conference in the autumn of 2024. An important milestone has been reached in the DRPLA Research Programme as an experimental treatment has started in the US for a person with DRPLA. This is taking pla￿ via the n-Lorem Foundation who charitably provides experimental treatments to treat people with rare diseases that affect very people in the US. While there is a clear regulatory path to run such trials in the US, similar opportunities are being explored in other countries like the UK. It is possible that more people with DRPLA in the US and other countries might be eligible for this experimental treatment as well. Ataxia UK and CureDRPLA have announced this to their communities, and we are supporting UK-based families with DRPLA in exploring if this could be possible for them. We also attended the Patient Colloquium n-Lorem organised in October 2023 to better understand their mission and who might be eligible for treatment, as their work could also be relevant to other ultra-rare genetic ataxias. 16

tAXIA Working with Pharmaceutical Companies in driving research forwards towards treatments for the ataxias Ataxia UK continues to work with phanna companies who have ataxia programmes, supporting them in advancing their research. A number of companies are getting closer to the drug approval stage and are thus needing to collect health-related quality of life data to support them in seeking approval. Ataxia UK has worked with these companies to facilitate this process. Some of this data has been presented at research conferences and we welcome this sharing of data. We have also provided introductions to ataxia experts in a range of areas, provided information on the research landscape, and explained the opportunities available in developing treatments for the ataxias to companies considering drug development programmes in the ataxia field. We encourage companies to run clinical trials in the UK and we are pleased that during the year a trial testing the promising 'antisense oligonucleotide, therapy is taking place in people with SCA1 and SCA3 at the London ataxia Centre. Ataxia UK also supported companies in ataxia awareness raising activities. As more promising treatments are being developed for the ataxias, we are getting to the stage that companies are submitting drugs for approval via the regulators. Ataxia UK has been actively supporting this process. The pharmaceutical company Biohaven have submitted the drug Troriluzole for evaluation by the EU regulator, the European Medicine Agency, as a potential treatment for people with SCA3. As part of Ataxia UK'S work with Euro-ataxia we provided a comprehensive submission to the EMA, highlighting the impact SCA3 has on families, the urgent need for a treatment, and urging flexibility due to it being a rare disease with no treatments. We plan to engage with UK drug regulators and decision-makers as needed. Pharma Strategy Advisory Committee The Pharma Strategy Advisory Committee met three times during the year and provided useful advice to Ataxia UK on collaboration with pharmaceutical and biotech companies, maximising our impact, and ways we can support drug development process. Due to the drug approval of the first drug for FA in Feb 2023 the Committee focused on advising Ataxia UK on the work the charity can do in this stage of the drug development process. 17

Ataxia UK | Annual Report- 2023 - 2024 Multi-centre European and International Research Projects Ataxia UK research staff are often invited to be partners in European and international research projects, to provide patient organisation involvement and expertise and to assist in providing the perspective of people with ataxia. Often this involves grant applications to EU or other funding schemes for research projects, and the invitations are either directly to Ataxia UK or to be representatives of Euro-ataxia (the federation of ataxia charities in Europe). The involvement of patient groups in projects is becoming increasingly important to the success of projects. During the year we have been involved in supporting researchers submit new grant applications and hopefully some will get funded. These are the projects we have participated in over the year: Accelerating and expanding the drug repurposing pipeline for rare neurological, neurometabolic and neuromuscular disorders by exploiting SIMilarities in clinical and molecular PATHology {SIMPATHIC) Euro-ataxia is a partner in this project that focuses on nine different rare conditions, including Spinocerebellar ataxia type 3. It aims to find and test the effect of drugs that are already available to patients for other conditions (repurposed drugs). It received funding form the European Commission Horizon Europe programme. Ataxia UK'S Head of Research is a Euro-ataxia representative on this project. European SCA31Machado Joseph disease initiative (ESMI) The ESMI consortium has successfully established the largest cohort of systematically characterised patients with SCA3 worldwide. The consortium is also playing an important role in the development of biomarkers. This is an extremely useful resource for running trials in Europe. A number of important publications have arisen from this project. This project has been recruiting participants since 2017 and Ataxia UK'S Head of Research, Dr Julie Greenfield, has continued to participate in the Steering Committee as a Euro-ataxia representative. Since the EU JPND funding ended the Consortium has secured funding from phama companies to continue the project. 18

tAXIA Progression chart of spastic ataxias (PROSPAX) project The PROSPAX project, launched in June 2020, is a collaborative effort between neurologists across Europe, plus Canada. The project aims to study the progression of spastic ataxias over time, from the clinical to the molecular level, including brain imaging, markers of progression and animal models. The project focuses mostly on ARSACS and SPG7, but will establish a more general research framework applicable to other spastic ataxias over time. Euro-ataxia is involved in the project as an active partner representing European ataxia patients, and is being supported by Ataxia UK. A representative of the Ataxia UK Research team attended the annual meeting of this project, held in Turkey, and we have continued to produ￿ blogs and disseminated communications to the community. An active Patient Organisation Group is leading a Work package to create Patient Reported Outcome Measures, by creating and distributing surveys and gathering the views of people with ataxia on the impact of their condition on different aspects of their lives. The results of these surveys are being written up for publication in a scientific journal. TREAT-ARCA Project This project, started in June 2020, focuses on recessive ataxias and in particular ARSACS and ARCA2 (also called COQ8A). It aims to design a toolbox of treatments for these ataxias; including gene therapy in animal model systems ofARSACS and ARCA2. There have been a number of research dissemination activities and in September we organised a well-attended webinar on gene therapy. We are also working on gaining an understanding of people's understanding and expectations from gene therapies for the ataxias. This will be done via a multi- national survey to people with inherited ataxias. A Research team working on this has been set up including researchers and patient groups and Ataxia UK is leading this project. It is particularly important to gather the views of people with ataxia, as research is advancing at both preclinical and clinical stages for the ataxias, with the first trials already taking place in people with FA. The European Friedreich's ataxia Consortium for Translational Studies (EFACTS) This is a study originally funded by the European Commission and that is gathering vital information about the progression of Friedreich's ataxia (FA). The purpose is to generate a large FA patient database, alongside an 19

Ataxia UK | Annual Report- 2023 - 2024 integrated clinical and natural history database; this is be linked to a biological samples repository. It also aims to define a panel of clinical assessment tools for use in future trials. Data from this study has resulted in useful publications and is also being used to plan clinical trials. Ataxia UK have supported the project over the years. There are two Euro-ataxia representatives on the Steering Committee for this project, one being from Ataxia UK (Prof Barry Hunt). FA Global Clinical Consortium During the year efforts have progressed in combining the efforts of EFACTS with the other well established natural history study in Friedreich ataxia, FACOMS (includes people from US, Canada, Australia, New Zealand and India). These studies have been conducted in parallel with many similarities in protocol design, objectives and study conduct. A new FA Global Clinical Consortium and a harmonized global study protocol has now been established. Ataxia UK has a patient group representative (Prof Barry Hunt) on this Consortium. Cerebellum and Emotional Networks (CEN) This is a training network funded by the EU (Marie Sklodowska-curie Innovative Training NetrNork) that investigates the brain circuits that underlie emotional behaviour. The training network is focusing on the role of the cerebellum, a previously overlooked part of the brain, and its involvement in the control of emotions. The knowledge gained will inform the development of new therapeutic strategies for individuals suffering from emotional disorders. Ataxia UK'S Head of Research is the Euro-ataxia representative. PhaseAGE project ('Phase Transitions in Aging and Age-related Diseases,) This project is a capacity building, training Consortium funded by the EU, and lead by a researcher in Portugal. It includes research projects on the formation of 'aggregates' by a phenomenon of phase separation (e.g. as when oil and water separate) in neurodegenerative conditions and in ageing. In particular, they are focusing on SCA3, hence Ataxia UK'S involvement. Ataxia UK'S Head of Research is on the Scientific Steering Committee and has been involved in the evaluation of the progress of this training project, A face- to-face meeting was held in September in Portugal to support patient organisations in building capacity and Ataxia UK was actively involved in this event, with both the Head of Research and Head of seNi￿s participating and 20

tAXIA giving presentations on 'lnvolving patients and patient groups in research, and 'Engaging your community,. The talks were followed by small group discussions and an art exhibition, showcasing photographs and stories from people with the conditions and artistic images of the proteins involved in the conditions. Ataxia Global Initiative (AGI) The Ataxia Global Initiative is a worldwide research network with the goal of facilitating the clinical development of therapies for ataxias. Dr Julie Greenfield (Ataxia UK'S Head of Research) continues to be a Steering Committee Member and co-chairs the Policy and Patient Engagement Working Group, tasked with setting all the policies for the initiative. During the year there have been meetings to encourage further participation of patients group representatives in activities of AGI. During the year eight papers were published in a special series of the medical journal Cerebellum. These are consensus papers with expert guidance and recommendations in a range of topics covered by the working groups (clinical assessments, brain scanning, biofluid sample collection, digital biomarkers, assessments using smartphones, speech assessments, oculomotor assessments and data sharing and analysis in next-generation sequencing to help diagnosis). AGI works closely with the 'Critical Path to Therapeutics for the Ataxias, Consortium hosted by the US not-for-profit organization Critical Path Institute. This Global Consortium aims to bring together experts from across different fields of ataxia research, patient groups and pharma companies to create regulatory tools and strategies to catalyse the development of approved medicines for the ataxias. A crucial aspect of the Consortium is that it includes experts from regulatory bodies such as the US Food and Drugs Administration (FDA) in its discussions. Ataxia UK is a partner of this initiative and attends regular meetings. AT Society Collaboration Ataxia UK has continued to provide a research support service to the Ataxia Telangiectasia (AT) Society, supporting people affected by AT. During the year we supported them in their research grant programme, and other research activities. A new Biomarkers in AT Working Group was established by the AT Society to progress this area of research and a review paper has been drafted for publication. In addition, work is underway to organise an AT clinical research meeting in 2025. 21

Ataxia UK | Annual Report- 2023 - 2024 Recruitment of Participants to Research Studies Having a database of people with ataxia puts Ataxia UK in a unique position to support research via the recruitment of participating volunteers. During the year we have supported 23 studies find participants. This includes studies understanding balance and gait, speech difficulties and a clinical trial testing a medication. Ataxia UK also supported a researcher run two workshops on working with patient samples in neuroscience. Ataxia UK has an internal Ethics Review Committee who provides input on studies involving people with ataxia, as needed. Raising Awareness of Ataxia Research Ataxia UK research staff have attended meetings and conferences throughout the year. This has been very useful in raising the profile of ataxia and Ataxia UK, creating opportunities to establish new partnerships and encouraging further research in ataxia. Ataxia UK'S Research Aims for 2024- 2025 Host the International congress for ataxia research in London Work with pharmaceutical company to accelerate access of Skyclarys to UK patients Actively engage with pharmaceutical companies who have drugs close to approval Gather the views of people with ataxia on gene therapies Care and Support Services for People Affected by Ataxia Care and support aims for 2023-24 Secure funding to sustain and enhance the complete range of Ataxia UK Services Provide another Occupational Therapy placement for the University of Brighton Expand the Helpline and Advocacy Service further Collaborate with Rare Minds to launch a dedicated Ataxia UK counselling servi￿. 22

tAXIA Pilot an Ataxia UK Specialist Nurse in the Southwest region to offer specialised care and reSoUr￿S to that community. Services Overview In July 2023, Ataxia UK achieved a significant milestone by securing five years of funding from the National Lottery Community Fund in England. This funding serves as a vital support for the expansion of our Helpline and Advocacy Servi￿. On the second year of this project, we are proud to announce the appointment of a Specialist Nurse. This role will facilitate the coordination of specialist services for people within the ataxia community, particularly focusing on the southwest region of England. where aC￿sS to specialised neurology services for ataxia patients is limited. Additionally, the funding has enabled us to appoint a second part-time staff member to enhance the Helpline and Advocacy Sep￿iCe, allowing us to reach and assist more individuals affected by ataxia. Furthermore, we have successfully secured additional funding to fulfil the match-funding requirement of the Lottery Project and to support various other essential seniices. Ataxia UK had the privilege of hosting its third Occupational Therapy placement, welcoming students from the University of Brighton, furthering our commitment to education and collaboration within the community. Community Activities We hosted a diverse range of 45 virtual activities, drawing in over 761 participants, a notable increase from the 540 participants in 2022-2023. These activities included monthly wellbeing sessions, Occupational Therapy activities, and noteworthy events such as Wellbeing Week, Volunteers Week, and various information sessions. With the exception of one in-person event in October 2023 we have continued to develop activities in a virtual format, ensuring the ataxia community can continue to aC￿sS key services and support. These activities have proven to be an effective means of enhancing the wellbeing of participants and fostering a sense of community for people affected by ataxia. All About Ataxia All About Ataxia seminars provide people who have a relatively re￿nt diagnosis information about ataxia, although we know that people who have been diagnosed much longer have also found them useful. 23

Ataxia UK | Annual Report- 2023 - 2024 The sessions were conducted three times this year, a decrease from quarterly in the previous year, although the total number of attendees increased with 82 participants in 2023-24, up from 70 in 2022-23. Sign-ups per session were higher, notably boosted by the in-person All About Ataxia event held before the National conferen￿ in October, which attracted 37 attendees. All About AtaxiaPLUS All About Ataxia PLUS is a series of information seminars developed by the ataxia community and Ataxia UK, and is aimed at bringing people in the ataxia community together to share information and learn from each other. Each All About Ataxia PLUS session delivers information on a particular subject which is important and helpful for people with ataxia and their friends, families, and carers. Three sessions of All About AtaxiaPLUS were delivered, focusing on practical tips and tools for individuals with ataxia. The initial session, All About AtaxiaPLUS Life Hacks, was attended by 23 participants and garnered positive feedback. Building on its success, the session evolved into All About AtaxiaPLUS Gadgets, Aids & Adaptations, delivered during Wellbeing Week to 48 participants, receiving highly positive feedback once more. A session titled All About AtaxiaPLUS Your Mental Health was collaboratively developed with Rareminds, reaching 23 attendees. Wellbeing Week Hosted in January 2023 Wellbeing Week was a series of free virtual workshops designed to increase emotional and physical wellbeing with the ataxia community. Attendance was high and feedback overwhelming positive with many attendees asking for more of the same. The sessions included topics such as Managing Symptoms, Exercise, Speech Therapy, Gadgets Aids & Adaptations, and Mindfulness. A total of 343 individuals registered for these sessions, with 255 attendees participating. Following each session, all registrants were sent a follow-up email containing access to watch the session again, presentation slides or handouts, a feedback survey link, and responses to any questions posed during the session, as applicable. Volunteers, Week To celebrate Volunteers, Week, we expressed our gratitude to all our volunteers by sending hand-written thank you cards and hosting a special volunteers week quiz. 24

tAXIA Branch and Support Groups Ataxia UK'S Support Groups and Branches are vital hubs of support and activity, all powered by the dedication of Ataxia UK volunteers. These groups provide invaluable spaces for sharing support, information, and camaraderie, hosting a total of 186 meetings with more than 1135 attendees. Support Groups, totalling 36 across the UK, offer members the opportunity to connect, share experiences, and unwind. Our 5 Branches serve as local arms of the charity, each with a Chair and Treasurer, actively support group meetings and activities throughout the year. In addition to geographical Support Groups and Branches, we also have 5 non- geographical support groups, catering to specific needs within our community. These include the Virtual Support Group, designed for remote connection, the 16-30s Group for younger members, and specialised groups such as the Episodic Ataxia Group. Re￿ntlY introduced are the Carers and the Autoimmune & Gluten Ataxia Support Groups, both established within the last year, enriching our support network, and meeting the diverse needs of those affected by ataxia. Volunteering Ataxia UK is deeply grateful for the invaluable contributions of our dedicated volunteers, totalling 89 individuals, many of whom perform multiple roles, including 6 new recruits. Our volunteers are the backbone of the organisation, actively supporting various facets of our work. They play pivotal roles in on the Helpline, by responding to queries, providing support and processing new Friend applications, and ensure the smooth operation of our branches and support groups. Additionally, they contribute to the development and delivery of virtual activities, participate in clinics at specialist ataxia ￿ntres, and tirelessly fundraise to sustain our mission. Moreover, many volunteers serve on committees and advisory groups, lending their expertise and passion to further our cause. Ataxia UK recognises and appreciates the indispensable role of our volunteers, without whom our work would not be possible. Diverse Placements We facilitated a diverse placement opportunity by hosting two occupational therapy students from the University of Brighton. Throughout their placement, they actively engaged with our community, participating in various support group meetings to offer insights into occupational therapy. Additionally, they conducted an Occupational Therapy drop-in clinic and led a session highlighting how occupational therapy can assist carers. Furthermore, they 25

Ataxia UK | Annual Report- 2023 - 2024 worked one-to-one with members of the ataxia community, gaining valuable firsthand experience of the challenges faced by those affected by the condition and deepening their understanding of living with a rare progressive neurological condition. Throughout their placement, the students were supported by the Ataxia UK seprfices team and received long-arm supervision from a consultant occupational therapist, who is also a member of the board of trustees and themselves a person living with ataxia, further enriching their learning experien￿. Scottish Advice Service Ataxia UK'S Rare Conditions Advice Pilot, in collaboration with Parkhead CAB in Glasgow, aims to pioneer and evaluate tailored advisory services for individuals with ataxia in Scotland. Through robust evidence gathering, the project seeks to influence social policy and support frameworks for other rare conditions, extending beyond ataxia. In its first year, the project recruited and trained a Rare Conditions Adviser, promoted the service through various channels, and facilitated collaboration between Ataxia UK and CAB staff. The project's initial findings reveal the complexity of client cases, with an average of 18 issues per person, significantly higher than standard advice services. Challenges include cross-border referrals due to the absence of a Specialist Ataxia Centre in Scotland. However, the project has increased awareness and capability among frontline advisers, improved communication strategies, and enhanced service delivery channels. Partnering has facilitated knowledge exchange, proving valuable amid Scottish benefit devolution. Plans for the second year involve continued support for the ataxia community, sharing project learnings, and undergoing rigorous external evaluation. Helpline & Advocacy Service Helpline Ataxia UK'S Helpline received a total of 1,350 contacts, providing support to 996 individuals across a range of concerns, covering 1,645 distinct issues. These included the provision of information about ataxia, health needs, therapies, referrals, and diagnosis. Furthermore, our assistance extended to addressing social care requirements, such as housing, aids, and adaptations, as well as navigating welfare benefits. grants, and financial matters. 26

tAXIA During this period, we welcomed 4 new volunteers to join our Helpline Team, bolstering our capacity to provide support. Regrettably, we also bid farewell to two volunteers who contributed significantly to our efforts. Advocacy Service Due to increased staff hours, over the past year Ataxia UK'S Advocacy Servi has been hard at work, handling 118 cases and providing vital support to 94 people in our community. The support covers a range of issues as stated above with particular focus on benefits (31 cases), navigating the NHS (33 cases) and grant applications (28 cases). In addition to achieving outcomes like access to specialist health services, appropriate adapted housing and adequate care and support, the service has secured £14,877 in grant funding for specialist equipment and services and £19,403 in unclaimed welfare benefits. Membership We welcomed 696 new Friends of Ataxia UK in 2023-24, that is up from 575 last year. Care & Support aims for 2024- 2025 Review content and format of All About Ataxia seminar to encourage attendance Connect with the ataxia community by attending Ataxia UK Branch & Support Group meetings both online and in-person Roadshows to devolved nations Enhance volunteer support by providing superlision by Rareminds for Helpline Team Develop and deliver more All About AtaxiaPLUS sessions Update website information Introduce evaluation strategy for ServI￿S Extend Helpline opening hours Increase the number of people supported by the Helpline and Advocacy Servi 27

Ataxia UK | Annual Report- 2023 - 2024 Improvements in Treatments & Care Treatment & Care aims for 2023-24 Develop 'Virtual Grand rounds, for expert advice on ataxia patients, diagnosis and management Hold Euro-ataxia annual conference in Gree Publish Ataxia Medical Guidelines Pilot an Ataxia UK Specialist Nurse in the Southwest region to offer specialised care and resources to that community Expand the Speech Therapy Service to support those Friends who are waiting for or unable to access the course. Develop 'Virtual Grand rounds, for expert advice on ataxia patients, diagnosis and management Following advice from Ataxia UK'S Medical Advisory Panel (MAP) during the year we launched 'Virtual Ataxia Grand Rounds,. A successful pilot was held during the year, involving two difficult ataxia cases being presented by clinicians to a group of four expert ataxia clinicians, plus Ataxia UK Research staff, who discussed the cases. Following positive feedback, a second grand round was held, and this time the event was publicised to UK clinicians who are on the Ataxia UK registry of healthcare professionals with an interest in ataxia to submit cases. This is a new useful service that Ataxia UK can provide in order to assist clinicians in cases that require expert input in diagnosis and management of cases with ataxia. We plan to run more Grand rounds over the coming year. Hold Euro-ataxia annual conference in Greece Euro-ataxia, of which Ataxia UK is an active member, is the federation of over 20 European ataxia patient organisations. Each year, Euro-ataxia organises a conference to enable patient groups across Europe to network and hear updates on research for the ataxias. The 2023 Euro-ataxia research conference was held in Greece, in May. More than 50 participants attended physically, including patient organisation representatives, people with ataxia, researchers, clinicians and pharmaceutical company representatives, as well as more than 20 who followed the event online. The event was organised by the Greek patient group (HEFAA) and Euro-ataxia, with support from Ataxia UK. 28

tAXIA The research conference was very successful with a range of interesting research talks, a panel discussion with people with ataxia, updates from pharma companies. The presentations covered a wide range of topics, including gene discovery, improvements in diagnosis, emerging and existing therapeutics, natural history studies, and biomarkers of ataxia. Flash talks from four early career scientists were included to promote their research findings. Engaging junior scientists in a patient-centred research event such as this is beneficial in broadening their perspectives on the needs of people with ataxia, highlighting the importance of their research and encouraging them to continue their careers in ataxia research. Interviews were also conducted with patient group representatives, researchers and clinicians to get their perspective on important issues facing the ataxia community. We were successful in getting a grant from the European Union's Horizon 2020 research and innovation programme (under the EJP RDCOFUND-EJP N. 825575), and sponsorship from pharmaceutical companies, meaning we could offer participants contributions to the cost of attending. The first day was dedicated to the research conference and the second day was for Euro-ataxia members only. The main topic of conversation was the progress made in individual countries on access to Skyclarys the first approved drug for FA (see above) and member groups were able to share what is happening in the different countries. Publish Ataxia Medical Guidelines Progress is being made in updating the Ataxia Medical Guidelines to help health professionals diagnose and manage people with ataxia. Specialist contributors for all sections have been identified and many sections have been updated. The Guideline Development Group has been reviewing the sections throughout the year. As this is a very long document, there have been delays and we were not able to publish them during the year. Pilot an Ataxia UK Specialist Nurse in the Southwest region to offer specialised care and resources to that community Funding secured in 2023-24 from the National Lottery Community Fund will enable Ataxia UK to appoint a Specialist Nurse in the Southwest region. The Nurse will be appointed in early 2025. Funding secured in 2023-24 from the National Lottery Community Fund will enable Ataxia UK to appoint a Specialist Nurse in the Southwest region. The Nurse will be appointed in early 2025. This region lacks access to ataxia specialist servI￿s, as the specialist centres in London, Oxford, and Sheffield are quite far away. The introduction of a 29

Ataxia UK | Annual Report- 2023 - 2024 specialist nurse will significantly improve access to appropriate, coordinated, and specialist care for people with ataxia in the Southwest. Expand the Speech Therapy Service to support those Friends who are waiting for or unable to access the course The Gift of Speech project seeks to address the speech difficulties faced by people with ataxia. We offer an online speech therapy course aimed at slowing the progression of ataxia speech symptoms. Additionally, we fund voice banking services that facilitate the development of a customised synthetic voice to be used with a communication aid in the event that speech becomes incomprehensible due to ataxia symptoms. Speech Therapy Our Speech Therapy program consists of a 6-week course that begins with four individual sessions with our Speech and Language Therapist. During these initial sessions, participants receive personalised guidance to identify and work on areas for speech improvement. Following this, participants join a small group of 5-6 individuals for daily sessions over the next 4 weeks. There are five group sessions each week, one of which is led by the Speech and Language Therapist. 60 Friends of Ataxia UK have undertaken the course and there are a further 38 people on the waiting list. We are excited to have recruited a second speech and language therapist to help us deliver the course more regularly. To accommodate those on the waiting list and for individuals in our community who may be unable to commit to a six-week intensive course, Ataxia UK delivered two standalone speech therapy sessions. Voice Banking We now offer funding for people with ataxia to bank their voice with Speakunique. vol￿ Banking involves recording an individual's natural voice, to be used to create a personalised synthetic vol￿. This means people can retain their identity and communicate in a voice that sounds like their own, even when natural speech is not possible. vol￿ Banking is designed to be inclusive, ensuring that everyone has access to a personalised synthetic voice, even if their natural Vol￿ is already unintelligible. Voice Design uses various voice characteristics, such as age, gender, and regional accent, to create a unique and tailored voice. Additionally, individuals have the option to use old recordings or donor voices to create their synthetic voice. 30

tAXIA Since we launched in 2022, we have funded 38 people with ataxia to download their personalised voice. In addition to this, 163 people with Ataxia have registered with Speakunique and of those 81 people have completed the voice banking process and created a vol￿. Other Activities Supporting Improvements in Treatments & Care Medical Advisory Panel meetings Ataxia UK'S Medical Advisory Panel met twice during the year (June and November 2023) and provided advice to Ataxia UK on a number of important topics. The meetings are also an opportunity for Ataxia UK to provide an update on the latest activities and for the group to be kept updated on research developments they are each involved in. A main topic of discussion was the approval of the first drug for adults with FA and its implications for UK patients (see research section). Other discussions focused on progress with the Virtual grand rounds, results of a treatment trial for SCA27B, and issues around lack of funding for Brain banks. Value of Treatment Project - evaluating the work of Ataxia Centres Ataxia UK is a partner in this European Brain Council project, that focuses on evaluating coordinated care in three rare neurological diseases. The ataxia study is being conducted Prof Giunti at the London Ataxia Centre. It has involved surveying people with ataxia in the UK, Germany and Italy to assess the value of Ataxia Centres. The results of this project highlight the value of coordinated care and specialist centres in addressing the challenges for people living with ataxia. Patients attending Specialist Ataxia Centres felt the care they received was better than those in non-specialist settings. There was no significant difference in the cost of the two different settings. Over the year two papers based on this research have been accepted for publication in peer-reviewed medical journals.The first focuses on the dIfferen￿S to the care that people with ataxia may receive in the different settings and the second paper focuses on the differences in costs. A third paper has been submitted to a journal presenting more detailed information on the UK setting. Prof Giunti was also invited by the European Brain Council to present the data at an event in Brussels on Rare disease day (29th Feb), thus increasing awareness further. 31

Ataxia UK | Annual Report- 2023 - 2024 Ataxia UK Ethics Review Committee Research studies, such as surveys, that are distributed to Friends of Ataxia UK or shared on our social media channels are first reviewed by the Ethics Review Committee. This Committee comprises five members, who either have ataxia or are family members of people affected by ataxia. During the yearthe Committee reviewed six surveys and interview-based studies, information leaflets to be provided to participants of an upcoming trial and a research workshop. Raising awareness and understanding of ataxia amongst healthcare professionals - Healthcare professionals, registry We continue to reach out to healthcare professionals with an interest in ataxia via our e-newsletters sent to 545 people on the Registry four times a year. In particular we publicised the publication of the Optimal Clinical Pathway for adults with movement disorders in England. The optimal clinical pathway sets out what good treatment, care and support looks like for people with neurological conditions, from those experiencing the first symptoms, to those that have lived with such conditions for a long time. Following lobbying by Ataxia UK this pathway includes an Ataxia Health Care Pathway, developed by ataxia specialists and Ataxia UK. This shows the ideal route to care within the NHS in England for people with ataxia, and emphasises the important role of the specialist ataxia centres. This is part of a suite of optimal neuroscience clinical pathways that have been developed by the neurological community, with the support of NHS England and the National NeurOscien￿S Advisory Group. Consultations for changes in healthcare services Response to consultation by HFEA (Human Fertilization and Embryology Authority) on use of PGT Ataxia UK provided a response to a survey created by Genetic Alliance to be submitted to the Human Fertilization and Embryology Authority (HFE4) in helping them decide whether to license the reproductive technique, pre-implantation genetic testing (PGT), for couples with a chance of having a child with autosomal recessive spinocerebellar ataxia-17 (SCAR17). The response included information on the impact of the condition and recommended that families are given the choice to use PGT and hence recommended a license be granted. Ataxia UK also publicised the consultation to people with ataxia so their input could be gathered. The HFEA approved the use of PGT for this condition. This is part of ongoing efforts by Ataxia UK to 32

tAXIA respond to consultations when any couple seek a licence for a not-yet licensed form of inherited ataxia. Ataxia UK accredited Ataxia Centres Ataxia UK-accredited Specialist Ataxia Centres are centres of excellence, where people with ataxia re￿1ve the best quality of care from ataxia experts and a coordinated Servi￿ combining diagnosis, treatment, support and research. In order to re￿1ve accreditation Centres need to comply to criteria devised by Ataxia UK. Sheffield Adult Ataxia Centre - Royal Hallamshire Hospital Sheffield The team at the Accredited Ataxia Centre consists of two neurologists (Prof Hadjivassiliou and Dr Shanmugarajah) and two Ataxia Nurses, thus is a large concentration of expertise. In addition, they have close links with the Children's Ataxia Centre below, which facilitates the transition between children's and adult services. Prof Hadjivassiliou continues to publish extensively on ataxia research, in particular autoimmune ataxias. A grant was awarded last year by Ataxia UK, Coeliac UK and other funders to improve diagnosis and management of gluten ataxia, and this project is now underway. The Sheffield team are also organsing an Ataxia Trainaing Day for healthcare professionals in June 2024, and ataxia UK helped publicise the event. Ataxia Children's Centre at Sheffield Children's Hospital The Sheffield Children's Centre, staffed by ataxia specialist paediatric neurologist, Dr Santosh Mordekar, supported by an Ataxia nurse, continues to receive referrals and see children with a range of ataxias. London Adult Ataxia Centre- UCUUCLH National Hospital for Neurology and Neurosurgery The London Ataxia Centre, led by Prof Giunti, now runs four ataxia clinics a week, with the support of a full-time Ataxia Nurse. There is also a multidisciplinary clinic, where patients see the neurologist along with other healthcare professionals, such as speech and language therapists and physiotherapists. In addition, there is a vestibular clinic and neuro- ophthalmology and neuro-urology clinics, providing even more integrated care. Prof Giunti continues to be involved in numerous research projects including trials. Her research laboratory studies a wide range of ataxias and is the only 33

Ataxia UK | Annual Report- 2023 - 2024 UK site for European natural history projects on the SCAS and FA. Importantly this Centre was involved in the drug trial that lead to the first drug to be approved in FA, in addition to the laboratory studies that contributed data on the effectiveness of the drug. During the year a new treatment trial for SCA1 and SCA3 has started. The Centre is also supported by Ataxia UK clinic volunteers. Since the pandemic the support had changed from face-to-face to phone and online support., but we are now planning for return to face-to-face support (in addition to phone support as needed). London Paediatric Ataxia Centre The Paediatric Ataxia Clinic is an addition to the Adult London Ataxia Centre, at the National Hospital for Neurology and Neurosurgery (NHNN), enabling children with ataxia to re￿1ve care at this centre of excellence. The clinic team at the Paediatric Ataxia Clinic includes Professor Paola Giunti, Dr Shpresa Pula (consultant in Paediatric Neurology), and Katarina Manso (ataxia nurse). The Paediatric Ataxia Clinic leads a large translational research programme, which aims to put research findings into practice. It's primarily focused on the genetic basis of ataxias, particularly Friedreich's ataxia. They recognise the importance of clinical registries and gathering natural history data, so that when therapeutic trials are offered, their Servi￿ is "trial-ready". Children referred to the Paediatric Ataxia Clinic will need to be monitored and supported by local healthcare professionals between visits. Oxford Ataxia Centre at John Radcliffe Hospital The Adult and paediatric Centre was accredited in Oxford last year. The Oxford Ataxia Centre offers a specialised service for adults and children with a suspected or confirmed ataxia. The service is provided by a multidisciplinary team including two adult neurologists (Dr Tofaris and Dr Rinaldo), a clinical geneticist (Prof Nemeth), and a paediatric neurologist (Dr Martin). Euro-ataxia Euro-ataxia is the federation of ataxia charities across Europe, with 20 member groups from 15 countries. Ataxia UK'S CEO is the SecretaryGeneral and Ataxia UK'S Head of Research is the Research Advisor. 34

tAXIA The Euro-ataxia annual conference was held in May (see above). A new member, FARA Ireland, joined Euro-ataxia during the year. Various letters of support for new research projectshave been written to support ataxia researchers get funding from the EU and other funders. Euro- ataxia offers toprovidethe patient perspective and input to funded ataxia projects where needed. During the year one such applications has succeeded in getting funding, which lead to the establishment of a Gene therapy Centre in Portugal. Lobbying for improvements in care and research We are active members of a number of representative 'umbrella' organisations, including Genetic Alliance UKIRare Disease UK, the Association of Medical Research Charities (AMRC) and the Neurological Alliances in England, Scotland and Wales. Sue Millman, CEO of Ataxia UK, is also a Trustee of Genetic Alliance UK. and Carol Mccudden, is on the Board of Trustees of the Wales Neurological Allian￿. All of these organisations seek to influence and improve investment, policy and practi￿ in activities and services which influence the lives of people affected by ataxia, and we actively engage in their training, policy development, surveys and lobbying activities. The Government launched the follow up initiative to the Rare Disease Strategy: The UK Rare Diseases Framework in early 2021. Sue Millman represents the Neurological Alliance (England) on the UK Rare Diseases Forum. The Forum enables engagement and collaboration between patient advocates, the UK Rare Disease Framework Board, the Delivery Groupl implementation boards for England and the devolved nations. The CEO has attended numerous meetings during the year regarding the Rare Disease Framework.

Ataxia UK | Annual Report- 2023 - 2024 Fundraising Our strategic fundraising priorities for the financial year 2023 - 2024 were: Maintain income, seeking modest growth where possible. Continual revision and improvement of our thanking process. Make improvements to our supporter journey - with a focus on improving digital usability, particularly on our website. Focus on fundraising streams which are traditionally more robust during times of economic difficulties - Trust and Foundations and Major Donor Fundraising. Maintain income, seeking modest growth where possible. FY23-24 was a mixed bag for income performance with growth in some channels and underperformance in others. The primary underperformers were in income streams we have less influence over such as legacies which ended the year 85 % below budgeted expectations. The positives though were seeing grovrth in Individual Giving and our Events and Community Fundraising which grew year on year by 3 % and 18 % respectively. Continual revision and improvement of our thanking process. Throughout the year we continued our focus on ensuring we thank our supporters as best we can for their generosity and support. To this end we held our first ever thank-a-thon in September 2023 which involved all members of staff across all departments join in with phoning, emailing, and writing to our supporters to thank them for their support. Make improvements to our supporter journey- with a focus on improving digital usability, particularly on our website Work on improving our supporter continued this year and we've rolled out the new design to a lot of the new website sections, and booking interfaces. A comprehensive holistic redesign, with particular attention paid to the top bNO layers of the website will be carried out in the Autumn of 2024. 36

tAXIA Focus on fundraising streams which are traditionally more robust during times of economic difFiculties - Trust and Foundations and Major Donor Fundraising. Much of the previous financial year and along with the early part of FY23-24 was focused on producing our bid to the National Lottery Community Fund requesting support over 5 years to support and transform our sepdice provision. l am very pleased to report that this application was successful in securing £499,251 over 5 years. Throughout the rest of the year, we focused on producing applications to match fund this amount. We also continued to implement our Major Donor Fundraising Strategy and built plans for 2 new initiatives to support this area of work to be implemented in FY24-25. Our Approach to Fundraising Ataxia UK has an in-house fundraising team undertaking a range of activities including: Direct marketing Events and community fundraising Legacy fundraising Trusts and Foundations Major donor fundraising This financial yearwe worked with an agency-"The Fundraisers"_ who helped us prepare Trust and Foundation bids throughout the year. All their work is monitored and reviewed by Ataxia UK before submission. We did not work with commercial participators this financial year. Supporters fundraise on our behalf and are given support throughout their event by our dedicated Events and Community fundraisers. Ataxia UK is registered with the Fundraising Regulator, and we are committed to following the Regulator's Code of Practice and Fundraising Promise which set the standards for fundraising behaviours in our interactions with the public and our supporters. We have a Vulnerable Persons Fundraising Policy which sets out how we identify such potential vulnerability and how we aim to respond in such circumstances. In this financial year we received complaints relating to our fundraising including, 2 complaints about the content of our appeals, 1 relating to a missing thank you, 1 relating to the lack of accessible challenge events, 1 37

tAXIA In Q3, a new Communications & Marketing strategy was agreed by thr board, setting out the goals for Ataxia UK'S sustainable digital growth as well as a variety of improvements to traditional means of communications. The plan is spread across the years 2023-2026. While the primary focus of this strategy is digital growth, it also encompasses traditional marketing and plans on how to streamline the flow of information and user journeys from traditional channels to digital channels and vice versa. In addition to supporting the main charity objectives being at the heart of this strategy, it also pays particular focus to ensuring we move towards more inclusive, accessible, data and user insight-driven decision making. Complete and launch our first full length ataxia documentary Filming and production of our first full length ataxia documentary continued in FY23-24 and will be launched in autumn 2024. Continue improving our core services l infonnation dissemination The communication team is a key component in ensuring the vital information and resources are made available to the community. Some highlights of how they made this happen in FY23-24 are: Improving page load speeds on the website making the website more user friendly and improving their experience Simplified our online joining process meaning supporters are becoming friends of Ataxia UK in 5 mins as opposed to the 20mins it took previously Increased subscriptions to our monthly newsletter by over 15 /0 39

Ataxia UK | Annual Report- 2023 - 2024 Financial Review For the year ending 31 March 2024 Overview 2023124 again proved to be a challenging economic environment for the charity, however, we continue to be very grateful for the continued support and generosity of our supporters. The charity will continue to ensure that our income is used in the most effective way to meet our strategic goals. The Balance Sheet and Statement of Financial Activities shows a significant improvement in Ataxia UK'S funds, as a result of a £488K surplus in the year (2022123: £167K). The charity has improved from a net asset position of £39K in the 2022123 financial year to a net asset position of £528K in the current year. A small net liability position still exists for the restricted funds on the balance sheet due to the 3 years expenditure commitment being made for the DRPLA and NKX6-2 projects in 2020121, whilst the funding will be received gradually over the 3 year period of the projects. The projects had a delayed start so the funding was pushed out by a further year but the situation is now almost resolved and is the reason for the accounts showing such a good net asset position. The deficit in restricted funds, of which DRPLA and NKX6-2 funds are part, have decreased over the year to (£16K) (2023: (£687K)). General unrestricted funds have unfortunately decreased to £543K (2023: £726K) due to the costs of running the charity increasing at a greater rate than the income. Further details of this are given later in this review as are details of reserves. We continue to maintain a healthy cash flow and have cash at bank and in hand of £1.9 million. Review of income Income £1,816K U2K C¢+nlc 40

tAXIA Total income for 2023124 was £1,814K (2022123: £1,450K) an increase of Donation income was higher than the previous year, £830K (2022123: £743K) an increase of 11.70/0. Legacy income was exceptionally low and decreased to £32K for the year (2022123: £218K), a decrease of 85 %. We had a good pipeline of legacies about which we had been notified, but very little came to fruition during the year. Income from fundraising activities increased to £286K (2022123: £242K) an increase of 18 %. Childlife income remained at £100k (2023: £100K). Grants receivable increased to £554K (2022123 £76K), a 629 % increase which was due to income relating to the DRPLA and NXK6-2 projects above. Conference income dropped to £14K, (2022123. £20K) a decrease of 30 %. Review of expenditure Expenditure £1.325K Raising Awareness E193K Research activi￿ £382K Care Services £243K £150 Total expenditure for 2023124 was £1,325K (2022123: £1 ,283K) an increase of 3.2 % . Spending on research activities decreased to £382K (2022123: £512K), a decrease of 25 % . This was partly due to a reduction in research grants made during the year; £101 K (2022123: £188K), a decrease of 46 %. The detailed breakdown of the research grants made can be found in note 9. There was a 21 % decrease in spend on care ServI￿S to £243K (2022123: £307K). Cost of raising awareness increased greatly from the previous year to £193K (2022123: £1 OOK) an increase of 93 %. This is largely related to the annual conference, Ataxian production, and an increase in salaries required due to the high cost of living. Expenditure on raising funds increased by 33 % to £271 K (2022123: £203K), and on generating funds to £150K (2022123: £93K) a 61% increase. Both were due to an increase in salaries because of the high cost of living and also trust fundraising. Governance costs increased by 26.5 % to £86K (2022123. £68K). 41

Ataxia UK | Annual Report- 2023 - 2024 Reserves levels at year end 2024 {£KI 2023(£K 465 383 79 General funds Designated funds Total unrestricted funds 343 543 727 Total restricted funds Total funds held 1161 528 1687} 39 The charity saw an increase in reserve levels ending the year on £528K (31 March 2023: (£39K)), due to the total net income of £488k generated in the year. Restricted funds were (£16K) (2022123.- (£687K)), (detailed in Note 22) with their still being deficit positions for DRPLA and NKX6-2. These deficit positions have very much decreased in the year. Designated Funds totalled £79K (2022123: £343K) representing funds held at branches (8.7K) and other designated funds (£70k) as detailed under Note 21. The trustees have released 5 designated funds during the year and decreased one. These were unrestricted funds which were set aside by trustees for a future purpose but were felt to no longer be needed. A parental fund and Research conference fund remain; the conference fund relates to the ICAR conference to be held in November 2024. General resenies of the charity as at 31 March 2024 were £465K (31 March 2023: £384K) a 210/0 increase. The trustees consider that it is both prudent and appropriate as part of their risk management policy to maintain a minimum level of contingency within free reseNes to provide against any unforeseen changes in income andlor expenditure. The reserves policy has been updated slightly in 2024 to reflect the face that operating costs are impacted by one off incidents such as ICAR. Therefore the new policy is to hold unrestricted, undesignated reserves equal to a minimum of 3 months operating costs adjusted for out-of- pocket costs covered by research and services restricted income. This figure amounted to £312,704 as of 31 March 2024, and the total of unrestricted, undesignated reserves was £468,053. This reflects a balance between being prudent and allowing the charity to direct as much resource as possible into research and care activities. GOING CONCERN With the impact of the current economic climate on charity giving, the importance of having adequate reserves, as detailed above, continued to be a priority. We are blessed by the generous support of the ataxia community. We will maintain the close scrutiny of the management accounts and cashflow and take whatever steps necessary to ensure the continued viability of the charity. 42

Ataxia UK | Annual Report- 2023 - 2024 Independent auditor's report to the members of Ataxia UK Opinion We have audited the financial statements of Ataxia UK for the year ended 31 March 2024 which comprise the Statement of Financial Activities, the Balance Sheet, the Statement of Cash Flows and notes to the financial statements including a summary of significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102.. The Financial Reporting Standard applicable in the UK and Republic of Ireland (United Kingdom Generally Accepted Accounting practi￿}. In our opinion, the financial statements: give a true and fair view of the state of the Charity's affairs as at 31 March 2024 and of its income and expenditure for the year then ended. have been properly prepared in accordan￿ with United Kingdom Generally Accepted Accou nting Practice; have been prepared in accordance with the requirements of the Charities and Trustee Investment (Scotland) Act 2005 and regulation 8 of the Charities Accounts (Scotland) Regulations 2006 (as amended) and 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 Charity 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 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 trustees, use of the going concern basis of accounting in the preparation of the financial statements is appropriate. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, 44

tAXIA Independent auditor's report to the members of Ataxia UK may cast significant doubt on the charitable 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. Our responsibilities and the responsibilities of the trustees with respect to going concern are described in the relevant sections of this report. Other information The trustees are responsible for the other information. The other information comprises the information included in the annual report other than the financial statements and our auditor's report thereon. 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. In connection with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether there is a material misstatement in the financial statements or a material misstatement of the other information. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard. Opinion on other matters prescribed by the Companies Act 2006 In our opinion, based on the work undertaken in the course of the audit: the information given in the trustees, report (incorporating the directors, report) for the financial year for which the financial statements are prepared is consistent with the financial statements; and the trustees, report (incorporating the directors, report) has been prepared in accordance with applicable legal requirements. 45

Ataxia UK | Annual Report- 2023 - 2024 Independent auditor's report to the members of Ataxia UK Matters on which we are required to report by exception In the light of the knowledge and understanding of the Charity and environment obtained in the course of the audit, we have not identified material misstatements in the Trustees, Annual Report. We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 or the Charity Accounts (Scotland) Regulations 2006 (as amended) requires us to report to you if, in our opinion: sufficient accounting records have not been kept. the financial statements are not in agreement with the accounting records and returns. or we have not obtained all the information and explanations necessary for the purposes of our audit. Responsibilities of the trustees As explained more fully in the trustees, responsibilities statement, the trustees are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as they determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error. In preparing the financial statements, the trustees are responsible for assessing the Charity'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 trustees either intend to liquidate the Charity or to cease operations, or have no realistic alternative but to do so. Our 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 46

tAXIA Independent auditor's report to the members of Ataxia UK reasonably be expected to Influen￿ 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 are set out below. Capability of the audit in detecting irregularities In identifying and assessing risks of material misstatement in respect of irregularities, including fraud and non-compliance with laws and regulations, our procedures included the following: We enquired of management, which included obtaining and reviewing supporting documentation, Con￿rning the charity's policies and prO￿dureS relating to: Identifying, evaluating, and complying with laws and regulations and whether they were aware of any InStan￿S of non-compliance" Detecting and responding to the risks of fraud and whether they have knowledge of any actual, suspected, or alleged fraud. The internal controls established to mitigate risks related to fraud or non- compliance with laws and regulations. We inspected the minutes of meetings of those charged with governance. We obtained an understanding of the legal and regulatory framework that the charity operates in, focusing on those laws and regulations that had a material effect on the financial statements or that had a fundamental effect on the operations of the charity from our professional and sector experience. We reviewed the financial statement disclosures and tested these to supporting documentation to assess Complian￿ with applicable laws and regulations. We performed analytical pro￿dureS to identify any unusual or unexpected relationships that may indicate risks of material misstatement due to fraud. In addressing the risk of fraud through management override of controls, we tested the appropriateness of journal entries and other adjustments, assessed whether the judgements made in making accounting estimates are indicative of a potential bias and tested significant transactions that are unusual or those outside the normal course of business. 47

Ataxia UK | Annual Report- 2023 - 2024 Independent auditor's report to the members of Ataxia UK 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-complian￿. The risk is also greater regarding irregularities occurring due to fraud rather than error, as fraud involves intentional concealment, forgery, collusion, omission or misrepresentation. A further description of our responsibilities is available on the Financial Reporting Council's website at: www.frc.org.uldauditorsresponsibilities. This description forms part of our auditor's report. Use of our report This report is made solely to the Charity's trustees, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006 and under Section 44(1) (c) of the Charities and Trustee Investment (Scotland) Act 2005. Our audit work has been undertaken so that we might state to the Charity's trustees 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 Charity's trustees as a body, for our audit work, for this report, or for the opinions we have formed. 10 October 2024 Anthony Epton (Senior Statutory Auditor) for and on behalf of Goldwins Limited Statutory Auditor Chartered Accountants 75 Maygrove Road West Hampstead London NW6 2EG 48

During the 2023124 financial year. we had a net positive movement in total funds. The balance sheet shows a net asset position. The DRPLA and NKX&2 grants were agreed in 2020121 with the funding received over 3 years. Covid delayed the start of the grants and means the funding has been spread over a longer period and should be completed by 2026. See note 22 (note l DRPLA and note li NKX6-2) below for further details. The cost of living crisis has had an impact on donations and could continue to have an impact on the 2024125 financial year. We continue to take steps to ensure the continued viability of the charity. The cashflow was reviewed regularly to ensure that actual unrestricted cash was going to be adequate at all times. The Finance Committee meet regularly to monitor the situation and the fundraising department are continuing to pursue other ways to raise funds to safeguard income. To aid robust forecasting, a budget and associated cash flow have been drawn up for 2024-2026. The Trustees feel there are adequate reSoUr￿S to continue operating for the foreseeable future. The Trustees feel that there are no material uncertainties about the charitable company's ability to continue as a going concem. Accordingly, we continue to adopt the going concem basis in preparing this annual report and financial statements. c. Childlife: The Charty is a member of a consortium, with three other charrties, called Childlife, through which the member charities are able to collectivety raise funds for their respective causes through the operation of a combined payroll deduction scheme and donor development.
