Dwusign Envelope ID.. E70B400D-CA454D7F-BBCD-E4CD53DCE207 ROYAL MICROSCOPICAL SOCIETY Report of the Board of Trustees for the year ended 31 December 2024 Foreword to the 2024 RMS Annual Report Dr Peter O'Toole, RMS President As we come to the end of 2024, we can reflect on another action-packed year in which the RMS delivered a wide range of high-profile events and other activities in support of the microscopy, imaging and flow cylometry communities. This year the Society hosted more than 30 meetings, conferences and courses, reaching an increasingly diverse, global audience. This included a number of virtual meetings and webinars, helping lo improve accessibility for our international community as well as achieving our aims around inclusivity and sustainability. As noted in the 'Evenls' section below, the RMS has stepped up its presen￿ as an exhibitor 81 external events- both in the UK and overseas. We view this as an essential part of reaching out to partner organisations, broadening the RMS'S reach and cementing ils position as an international Society at the forefront of microscopy, imaging and flow cytomelry. The highlight of this year's events calendar was undoubtedly elmi2024 in Liverpool. which the RMS hosted as an in-person event for the first lime since 2018. This really is one of the biggest and best events in European microscopy, and hugely important for the Light Microscopy Community- both for the researchers themselves and the manufacturers of their equipment. The event was a great success and the positive feedback from attendees is leslamenl to all the efforts of the organising committee, RMS staff, volunteers and countless others. We are already looking ahead lo mmc2025, taking place in Manchester next year, and l am sure this will prove to be one of the biggest and best ever instalments of the Congress Series. Any membership-based organisation ultimately thrives on its ability lo appeal lo new audiences as well as the retention of existing members. On this S￿re I'm delighted lo note that the number of individual RMS members increased by more than 20 per cent during 2024. This was largely driven by a healthy influx of student members, who we hope will continue lo have a long and happy association with the Society. 11 is really great to see the impact of our efforts lo support Early Career Mi¢ros¢opists as well as people at all career stages and those using miuoscopes PLJrely for study or pleasure. As a society, we are mindful of the need not only to deliver for our academic and individual membership, bul also for our corporate members. To that end, we have a highly engaged Corporate Advisory Board, and a number of developing schemes, such as our collaborative, RMS- hosted Corporate Member Events. These webinars are making available some fantastic, free content lo members and non-members alike, and we hope lo continue and develop this initiative next year. Our Education and Outreach activities have continued apace during 2024, including the loaning OLJt of well over 100 Microscope Activity Kits lo primary schools. This is a wonderful and well-eslablished scheme providing a first taste of microscopy lo thousands of children. Meanwhile the Hilachi High Tech America STEM Education Outreach Programme has remained extremely active, bringing port8ble electron microscopes lo secondary schools across the UK. We currently have no fewer than 10 RMS Diploma candidates progressing well through their studies, and six RMS annual summer sludenlships were awarded to projects this year in the fields of life, physical and multidisciplinary sciences. Our Outreach and Education Committee is also developing exciting plans to offer professionally accredited programmes to our membership, including Chartered Microscopist and Registered Technician status. More detail regarding all these initiatives can be found below. Our flagship. peer-reviewed publication, the Journal of Microscopy, continues to go from strenglh-lo-slrength, with a large increase in the number of papers published online this year. We are particularly pleased lo see a significant growth in the proportion of papers published 'open access,, via funding agreements between authors, institutions and our publisher, Wiley. By removing the requirement for authors lo cover submission fees themselves, these deals are making it possible for many more authors lo publish their work in the Journal of Microscopy. Meanwhile our membership magazine, infocLJS, continues lo develop as a fully online publication, with a number of new initiatives- including publicly available articles being promoted on the RMS website- being tsken forward by the editorial board. As we come to the year's end. I feel it is important to highlight the efforts and dediealion of the RMS staff, led by Chief Executive Sali Davis, and all our volunteers and committee members. They make up a fantastic team enabling the Society lo carry out all its activities, while embracing new ideas and ways of working along the way. When attending our Section AGMS - which cover all branches of microscopy, data analysis and flow

E70B400D-CA454D7F-BBCD-E4CD53DCE207 ROYAL MICROSCOPICAL SOCIETY Report of the Board of Trustees for the year ended 31 December 2024 cylomelry - l am always struck by just how much each committee is actually delivering for the microscopy community on a global scale, and by the efficiency and professionalism of staff and volunteers in supporting this work. Despite a swiftly changing and challenging environment in both academia and industry, plus all the uncertainties in the wider world at present, they somehow manage to keep delivering for the microscopy commLJnity, and it is a great credit to them all. It is absolute privilege to serve as RMS President, and to witness the PrOg￿$S being made across the full breadth of our activities, as the Society continues to meet the changing needs of its membership and wider community. I would like to give special thanks to all our members for your continued support of this great Society. Governing Document The Royal Microscopical Society's goveming document is its Royal Charter. The Supplemental Royal Charter was obtained 9 October 2008. Objectives The Royal Microscopical Society s objects are constituted in Supplemental Royal Charter, they are= To promote the advan￿ment of miuoscopical science by such means as the dis¢ussion and publication of research into those branches of science where microscopy is important., and To organise educational activities Con￿rned with microscopy for the benefit of the general public and for the science community. Recruitment of Trustees All members of Council (ex￿p1 the chairs of the seclionsl must be elected al the Annual General Meeting and re-elected after three years in office. Every year the longest serving members of Council musl retire according to the agreed rotational pattern. They are not eligible to serve on Council during the year following their retirement. A notice inviting nominations from the Fellowship is published on the RMS website and in infocus magazine at least four calendar months before the Annual General Meeting. Al a meeting not less than three calendar months before the Annual General Meeting, Council nominates qualified persons lensuring a balance in experience, suenlifie expertise, and gender) for election as OfFicers and Ordinary Members. The list of Council nominations is published to all members of the Society not later than three weeks before the Annual General Meeting. This list also contains the names of any nominations from the members of the Society, if there are any. along with the name of the nominating member. If no candidates have been nominated by the membership, the persons nominated by Council shall be judged to be elected, and no ballot shall be held. In 2024, we slrenglhened ourgovemance by recruiting Lay Trustees, following recommendations from the Charity Commission. These Lay Trustees bring diverse perspectives from different sectors and backgrounds, offering impartial insights into external communities and environments. To ensure we have the right expertise on our Board, both new Lay Trustees and existing Trustees will complete a Skills Matrix assessment. This will help us maintsin effective oversight and fulfil our charitable aims and legal obligations. Additionally, we have implemented a Volunteer Agreement that clearly outlines expectations for all Trustees and Volunteers working with the Society.

In addition to this, all new Trustees receive a more detailed Iruslee Training Document. Further Trustee training lakes place al Council meetings every few years. Pay and Remuneration The pay of RMS staff is agreed by a remuneration committee consisting of the President, Honorary Treasurer and Executive Honorary Secretary. The salary scales are based on a University salary scale, and the staff members pay grades are linked lo the most appropriate scale where the breadth of responsibilities are similar. 2025 will see a review of the salary structure and the introduction of performance objectives in order to grow, improve and develop our dedicated staff team. Oryanlsatlon & Governance Structure The Executive Committee manages the Society's day-lo-day operations on behalf of the Trustees. This committee comprises.. The President Vice-Presidentlsl Executive Honorary Secretary Honorary TreasLJrer Honorary Secretaries Meeting quarterly, the ExeeLJlive Committee oversees operations through the Chief Executive, who serves as the Society's senior permanent officer. The Chief Executive reports lo Council through joint oversight from the Executive Honorary Secretary and Honorary Treasurer. The Chief Executive ensures all Council actions comply with the Society's Charter and By-laws, maintaining accountability lo Society members. To ensure smooth operations, the Chief Executive collaborates with the Finance Director and Event Director, holding delegated authority over-. Financial management Employment matters Event program coordination Principal Risks and Uncertainties The trustees have a risk management strategy which comprises.. an annual review of the principal risks and Un￿rtaInlieS that the charity fa¢o', the establishment of policies, systems and procedures to mitigate those risks identified in the annual review., and the implementation of procedures designed lo minimise or manage any potential impact on the charity should those risks malerialise. This work has identified that financial sustainability is the major financial risk to the charity. A key element in the management of financial risk is a regular review of available IiqLJid funds to settle debts as they fall due, regular liaison with the bank, and active management of lfftde debtors and creditors balances to ensure sufficient working capital. The RMS is aware that the Journal of Microscopy revenue is likely to decrease due lo Open-ac￿sS journal submissions. A procedure and plan has been pul into place lo reduce our overheads if this risk becomes more apparent. This risk is reviewed al least annually during Executive Committee Meetings, and as part of the overall Strategy Meeting. Allenlion has also been focussed on non-financial risks arising from Health and Safety issues, Disaster Recovery and a loss of reputation. These risks are managed by ensuring accreditation is up lo date, having robust policies and prO￿dureS in place, and regular training for staff.

Dwusign Envelope ID.. E70B400D-CA454D7F-BBCD-E4CD53DCE207 ROYAL MICROSCOPICAL SOCIETY Report of the Board of Trustees for the year ended 31 December 2024 The RMS is also aware of the data it pro￿sseS and ensures it complies with the latest security stsndards. With the implementation of GDPR, fines for data breaches have increased. This poses a heightened risk for the RMS as it is essential to ensure our data is secure. An ISO 27001 a¢creditslion has been achieved to ensure all potential risk is reduced and managed in line with the guideline sel out in the standards of the qualification. The Society is also exposed to risks associated with being an employer, eg legislation and liligalion, and take appropriate steps, including obtaining legal advice where appropriate, lo adequately mitigate the Society's exposLJre lo such risks. Fundraising The charity does not directly fundraise from the public. The RMS is a self-funded organisalion with any funds generated from its own activities reinvested into the scientific community. Occasionally the RMS may carry out fundraising activities for a specific project or to ensure the longevity of the society. The charity does not use any external fundraisers and any fundraising undertaken during the year is monitored by the Trustees. Any fundraising projects would be managed by the staff at the RMS, with guidance from the trustees, who would set out clear guidelines and benefits lo the community. The RMS would conduct a full risk assessment prior lo the fundraising activity and ensure that all vulnerable personnel are protected. At present the RMS has not received any complaints regarding fundraising aclivilies. The significant donation recognised in the current year arose from donations provided by trusts and societies, and not from public fundraising. RMS Awards, Medals and Honours in 2024 The RMS offers a wide range of award opportunilies for individuals making a special contribution within microscopy, flow cytometry and imaging. Each year we invite applications from across the globe, to ensure those making a real difference re￿1ve the recognition they deserve. This year's awards included the RMS Science Sedion Awards, the Ovlstanding Achievement Awards for mid- career researchers, the RMS Early Career Award, the Chris Hawes Education and Outreach Award and one new Honorary Fellowships.

As we approach the end of 2024, the RMS can reflect on another action-packed year in which we delivered a wide range of high-profile meetings, conferences, courses and other events in support of the microscopy, imaging and flow cytometry communities. This year the Society hosted more than 30 events in total, including a number of virtual meetings and webinars- helping lo reach a diverse, global audience. We recognise the benefits of online meetings in terms of increased accessibility, inclusivity and sustainability, and will continue to consider provision for remote attendan￿ on a case-by-case basis. We will also continue listening lo feedback from our event attendees and members. The first six months of 2024 saw UK Light Microscopy Facility Meeting 2024., Flow Facilities Meeting 2024- Virtual Flow Cytomelry Data Analysis Course Spring 2024,. EM-UKI 2024,. AFM & SPM 2024,. Virtual Facility Management Training Course 2024,. and Intr(￿UctIon to Image Analysis (Dublinl. Our online events also included the highly successful Expansion Microscopy User Group Meetings Wlth our partner organisalions in both North America and Australia, and a further inslalmenl of the Virtual International Microscopy Lecture Series, featuring Dr Harald Hess. This yearfs stsnd-oul RMS event was elmi 2024 (The European Light Microscopy Initiative), held in Liverpool, UK, from 4 - 7June. 11 was the first time the Society had staged elmi as an in-person event Sin￿ 2018, and once again the meeting lived up to its reputation as one of the most highly regarded in the microscopy calendar. This really is one of the biggest and best events in the European microscopy calendar, and hugely important for the Light Microscopy Community- both forthe researchers themselves and the manufacturers of their equipment. The year continued apace through summer and autumn, with Light Microscopy Summer School 2024 (Yorkl., Gelling the most from your Confocal Course 2024 Iyorkl,.

Out of the lolal 369 Student members, 164 are undergraduate students. We are always grateful for the support given to us by our Corporate Members and are pleased lo report that eight new companies joined us in 2024, bringing the totsl number of Corporate Members to 68. The Society aims lo increase membership numbers and has stepped up ils presence as an exhibitor al external events this year to actively recruit new members. We also urge all existing members to encourage others who might be interested in joining. We value and appreciate the support given to us by our members, and we remain confident that RMS Membership continues lo offer a real benefit to microscopisls worldwide. We are proud lo be a truly international organisation and are pleased to be able to offer as a benefit to members, membership of the European Microscopy Society. Members who did not renew their subscription in 2024 have told us this was largely due to external circumstan￿S and not because the membership failed to provide value lo them. Education and Outreach By Dr Kerry Thompson, RMS Honorary Secretary Education and Chair of Outreach & Education Committee Over the last 12 months we have worked on Some new initiatives related lo outreach, education and professional development, and I will discuss them amongst our long standing other activities and programmes. Our Microscope Activity Kits have continued to be loaned out to primary schools this year, and we have distributed more than 105 kits, which is f8ntaslic. This work is superbly facilitated by the excellent RMS office staff and the team in Oxfordshire Employment and County Print Finishers. The MAKS remain ever popular within the primary education sector and are still very sought after for Science Festivals and Fairs. We are continuing lo work on an Image Analysis activity for schools, which is being led by Stephen Cross from the DAIM Section. Stephen is working hard on various interactive controls including graph and measurement fun¢tionality and the sele¢tion of regions and annotslions within the example data. As the ever increasing Importan￿ and awareness of analysis skills and education becomes more and more apparent lo our larger community, we hope that this initiative will spark interest in this field with the younger generations. A huge thank you to all who have been involved to date. The Hitachi High Tech America STEM Education Outreach Programme, led by Alex Ball and James Perkins, has remained extremely active over the reporting period. For 202312024, the programme ran with one SEM. Despite this there have been over 12,700 students from both stale {770/.} and private school1230/.l engaged since 2020. Analysis conducted on the programme data by Aex and James has revealed that there have been 34 loans lo schools and four to museums, and the team have p8rticipaled in three workshops, two cOnferen￿S and one festival. Furthermore, the impact report delivered by our Professional Internship Placement PhD, student Zoe Barr, has demonstrated that participants engaged with the programme in a number of ways including.. Individual Sludenl Research Projeels, Lessons and In-class Demonstrations, along with Demonstrations and Workshops

In an eX￿rp1 from this report she notes The best support for STEM education relies on the design of leaching practices which provide the student with the most valuable leaming opportunities possible. Pedagogical frameworks aim to incorporate the curriculum outcomes, address Equality, Diversity and InGlusion (EDI) and inspire students with enlhusiasn7 for STEM." Once again we thank Zoe for her work on this report and look forward to the upcoming academic publication from the whole team. The 10 current RMS Diploma candidates are progressing well through their studies. Thank you to Susan Brookes for continuing her superb role as chair of the RMS Qualification Committee and to Marie Kokolski for supporting both Susan and Kale with the annual candidate progress presentations. We would like lo extend our warmest congratulations to Adam Coslin in Australia for completing his Diploma. Six RMS annual summer studenlships were awarded lo projects this year in the fields of life, physical and multidisciplinary sciences. Congratulations to the awardees., we hope you enjoyed your placements and look forward lo seeing your reports in infocus. The development of professionally accredited programmes continues, including, but not limited to, the Chartered Microscopist and Registered Technician. Thank you to our new Chief Executive Sali for really driving this initiative forward over the past 12 months. This has been a multistep process with involvement from the broader RMS community and members, along with a dedicated steering group which has representation from our sections and those interested in this space. After an initial survey with almost 300 responses deemed that the membership wanted the RMS to pursue this professional a¢creditalion, the work began in earnest. We are pleased to say that Privy Council Iwhose role il is lo grant permission for keeping a regislerl have approved the schedule needed to develop the register. We anticipate that the steering group will develop the course content and curriculum within the next 12 months and provide updates as appropriate. Thank you lo the Steering Group for your efforts to date and I look forward to continuing lo work with you on this exciting initiative to see il through lo fruition. Also under the professional development and training remit, I would like lo update you on the outcome of the recent RMS Training Survey. The survey had over 500 responses with participants from UK, USA, Australia, Germany, Spain and Ireland. A big thank you to the whole working group and also Georgina Fletcher for her excellent guidan￿ and keeping us on mission and lo tssk. Both the mentoring programme and the job shadowing initiative continue to be well availed of with Biolmaging UK and the RMS now supporting three years, worth of opportunities. I would like to draw attention to the newly fomied Microscopisl Profiles page on the RMS website. This excellent work led by Saskia Bakker is shining a light on the variety of roles, jobs and careers in which microscopy skills and knowledge are required. This page is not only useful as a resource lo direct undergraduate and graduate students towards, bul also to the larger community to really gain a better understanding of our collective diversity. l encourage you to submit your profile to help us build our representation. Thanks to Lucy ￿dIer in the office for designing and implementing the page so excellently. Finally, we had the pleasure of awarding this year's Chrrs Hawes Award for Outreach and Education to Mark Pickering, of University College Dublin. Alongside his research activities, public and community involvement in science are cornerstones of Mark's work. He has contributed to many national and international public outreach and engagement inilialives, including The Dublin Maker Festival, Skype-a-scientisl, the 'JellyLab' and the 'Science by the Sea, YouTube series. Mark is an eloquent advocate for the importance of Microscopy and STEM initiatives from primary lo tertiary education, and beyond. He is a wonderfully deserving recipient of this award and my congratulations go to him. Finally, I would like lo thank the Outreach and Education Committee members for their contributions throughout the past 12 months. It really is a pleasure lo Chair this committee and contribute to shaping the larger RMS mission. None of this would be possible without the continued support of the RMS staff who enable our efforts. A notable mention lo Kale, Jess and Jade for keeping me, and us all on track, and for their friendship and general 10

In addition lo the fLJII. digital issue, published each quarter, we also now publish selected articles from each issue, as individual, 'open access, features on the RMS website. These are promoted on social media lin addition to the full, quarterly issue) to help drive people lo the website and promote infocus Magazine lo an aLJdience beyond RMS members. Notable articles from the three issues published this year include a lengthy 'Picture Special, review of elmi2024', a comprehensive historical overview of microscopy-lhemed postage stamps by Joel Cohen., a piece by RMS Hon Fellow Professor Brian Ford on the lalesl developments in the authentication of original Leeuwenhoek microscopes,. and 8 review of the newly-opened Oxford-ZEISS Centre of Excellence ICoE} al the University of Oxford. Our De￿mber issue included allraclive articles on both foraminifera and diatoms., dual reflections from Jon Moss and Erin Tranfield on selling up an Electron Microscopy facility., and a piece by Tony Hayes of Cardiff University on a 3-D pollen library sel up lo aid research, leaching and science engagement aclivilies. The Editorial Board has also sought lo feature articles shining a light on RMS initiatives, such as the RMS Diploma and mentoring scheme. In March, we were also very pleased lo feature the reports of each of our 2023 Summer Sludenlships. Our 2024 Summer Studenlship reports have now all been received and will be featured in our March 2025 issue. The magazine continues to feature a wide range of content, with regular features such as the Events Calendar, New Member Profiles, Company News, and latest news from the Journal of Microscopy. Plans are also in pla for a new'Big Questions, feature, in which contributors offer their views on a topical issue in microscopy. The first subject we are planning to tackle is the impact of Al in microscopy. The editorial board is investigating new options for publishing content online, outside of the full issue each quarter for instance, the option of publishing 'early view, versions of articles prior to the'page design, stage, or summary articles providing a 'taster' of an article due to be published in the forthcoming issue. A number of new, online advertising opportunities are also now available, associated with the 'full' digital magazine, promoted 'open access, articles and our Infocus e-newsletter. The online format enables better monitoring of readership figures le.g. page views, 'clicks through, etc.) which is improwng our intelligence surrounding the performance of adverts, and the information we are able to provide companies. For instance, the promotion of our 'open access, features has made a significant impact on readership figures for these articles, enabling companies to reach a wider audience. Finally, we bade a fond farewell to Dr Laura Fumagalli, who stepped down from the infocus Editorial Board in July. Laura has made many contributions in helping shape the direction of the publication in recent years, and we thank her for all her efforts. The current infocus Editr)rial Board is as follows..

The @Journal X account currently boasts 4,120 followers- up from 4,024 at the end of 2023.we have stepped up engagement on the Journal account as part of wider efforts to promote the Joumal and boost article submissions. This includes greater use of images to promote individual articles, and regular posts to raise awareness of opportunities to publish 'open access, through Iransformalional agreements. Meanwhile, with the exception of Bluesky, the RMS Linkedln account remains the Society's fastest%rowing plafform on social media. In just the last 12 months OLJr audience has grown from 3,562 to 4,630 followers, an increase of almost 30 per cent. The RMS Facebook following remains fairly static at around 2,500 followers. Financial Review Report by Mr Rod Shipleyg Honorary Treasurer Foreword These accounts have been prepared in accordance with the Charity Commission Statement of Recommended Pr8Ctice which was updated in 2019. In accordance with these guidelines, indirect or support costs are allocated to each charitable activity based on the percentage of income provided by the particular charitable activity, eg if an activity generates 200/0 of the annual income, then 200/0 of Indi￿¢1 costs will be apportioned lo the aclivily. In this way an accurate representation of the costs of activities can be presented. A flagship event Imicroscience Microscopy Congress mmcl is staged every 'odd' years, so whilst a comparison of income between years is slraightfotward, a comparison of expenditure requires a level of understanding and inlerpretslion. This is because the per￿ntageS used lo apportion indirect costs change from year lo year, i.e. expenditure on 'meelings and courses, will include a larger proportB)n of indirect costs in a non mmc year. Overall The Society re￿iVed incoming resources of £1.681 M compared lo £1.886M in 2023. Our managed portfolio of listed investments, largely represented by funds under management by Ralhbones Incorporating Investec Wealth and Investment Limited, had a value at the end of 2024 of £3.698M12023.. £3.547MI. The overall value of the Society's funds, including the property and other investments al the end of 2024 was £5.448M {2023'. £5.325MI. When viewing the 2024 accounts, the following points should also be noted.. The totsl valLJe of the Society s fijnds has increased by £123K12023.. £132K) primarily due to the gain made during the year in our investment portfolio of £189K12023.' gains of £126KI. A planned operating deficit of £145K was seen in 202412023-. surplus of £6KI. Please note, the trustees agreed an operating deficit of £169K for 2024. This deficit includes additional staff costs relating to the planning for ime21 in 2026. £12K {2023.. £14KI has been spent on Microscope Activity Kit (MAKI equipment and logistics and £12K {2023.. £11.5KI on the summer studenlships Isee note 9}. An internal property valuation has been condueled by the Trustees which resulted in a £79K gain lof which £13k of the gain was atlribulable lo the property recognised as investment property) on the revaluation of the Fixed Asset. An amount of £54k has also been recognised to facilitate the pledged gift of Microscopy equipment lo the NHM. During the course of the year, the designated funds Iportions of the Society s free reserves that are ring-fencedl were used to support activities in the area of its Outreach programme. The value of the designated fLJnds and the expenditure charged to them appears in the accounts and provides the reader with a picture of expenditure in these areas (S￿ note 181. Generated funds The Society owns the Sl Clements building in Oxford and leases the ground floor to 8 restaurant. During 2015 8 new lease was negotiated which expires in 2039.

The cost of generating these funds was £43K12023.. £41 KI. Charitable activities Meetings and Courses During the year, the RMS managed to support the community with a combination of in-person and virtual events with a full calendar of RMS events. The lolal income from Meetings was £578K12023.. £177KI, and income from courses was £121 K12023.. £121 K). Expenditure on Meetings was £897K12023.. £334KI. Expenditure on Courses was £140K12023.. £93KI, please note, this expenditure includes an allocated contribution lo RMS salaries and overheads. The Society's policy on meetings and courses is that the income from a meeting should at least meet the direct costs of that meeting, and courses should try lo retum a surplus on direel costs Ibul excluding direct staff limel. Once the indirect costs are apportioned, meetings and courses made a deficit with expenditure exceeding income by £338K12023.. £129K deficit). A breakdown of direct and indirect costs for meetings and courses can be found in Note 8 of the accounts. Subscriptions Income from membership subscriptions increased to £136K {2023.' £120KI during 2024. We are grateful for the support given lo us by our Corporate Members. Publications The Society publishes the internationally recognised Journal of Microscopy and the membership magazine, infocus. In addition, we have back issues of the Journal of Microscopy dating from 1841 available through Wiley online. Together they generated income of £657K12023.' £602KI with expenditure of £511 K {2023'. £386KI. For many years the RMS has relied on the funds generated from the Journal of Microscopy lo financially support the activities of the Society. The drive towards Open Ac¢ess10A1 has put the Society at risk of a reduction in revenue from the JoLJrnal of Microscopy. The Society is now experiencing a steady decrease in income from the Journal, which could decrease lo approximately £255K within the next three years. The Executive Committee have produced working groups to review the following areas.. Increase income Decrease expenditure Journal submissions Outreach Outreach income of £1,32512023'. £9321 was received in 2024 with a further £65K of donation income which is largely generated from a donation towards the purchase of a SEM1£64KI and the sale of microscopes1£1.2KI to enthusiasts. These microscopes are donated to the Society by organisations and universities when they become surplus lo requirements. They are then restored and sold on by Dr Chris Hammond FRMS and Mr Chris Kennedy FRMS. The Society conlinLJes to be Indebted lo all of them for their time and expertise in generating this income. Efforts continue, via articles in infocus, to publicise this activity and to encourage organisations lo donate redundant and unwanted microscopes to the Society. Donations and grants The level of donations and grants expended was £80K 12023= £35KI, which includes expenditure on the Microscope Activity Kits, travel bursaries awarded to members and the accrued purchase of the outreach SEM. Governance costs Governance costs were £42K12023.. £38KI, comprising costs incurred for meetings of Council, professional fees (including the auditors feel, and a proportion of office costs.

Dwusign Envelope ID.. E70B400D-CA454D7F-BBCD-E4CD53DCE207 ROYAL MICROSCOPICAL SOCIETY Report of the Board of Trustees for the year ended 31 December 2024 Investment Policy General The Trustees of the Royal Micros(x)pical Society have appointed Investec Wealth and Investment to manage the portfolio of the Society on a discretionary basis. This Investment Policy provides a framework under which the appointed investment managers should operate. The Investment Managers should take into account the general nature of the Royal Microscopical Society and its principals and not knowingly make investments that may compromise the position of the Society. Objective The objective of the investment FX)rtfolio is to provide a retum over and above UK inflation as measured by UK RPI (Retail Price Index) over a long-lerm lime horizon in 8ddilion of 10 years. The Trustees aulhorise the use of multiple asset classes in order to achieve these returns irb a risk adjusted manner. Weighting In line with the medium risk mandate the Trustees would expect the investment manager lo be within the following weightings, except under exceptional circumstsnces., Medium risk Balanced Fixed Interest Equities Commercial Property Allernalive Investments Cash oo/. 100A 200A 300/. 400/. 500/. 6001. 7001. 80ts1. 900A 1000A The above chart details the asset classes in which the portfolio is to be invested and the likely weightings within each asset class. As markets are dynamic we will employ two types of asset allocation. The strategic asset allocation is the default neutral position for the portfolio weightings which we would adopt when conditions are normal or when there is no anlicipaled advantage in moving away from this position. This is represented by the middle line in each bar. As we rarely experience normal economic conditions then we employ a second much shorter term asset allocation called tactical asset allocation. The tactical position can be sel either side of the strategic position but within the maximum and minimum boundaries sel out above in each asset class. Risk The Trustees are comfortable with a moderate risk profile and are aware that the portfolio will be subject lo short term volatility given the exposure to capital markets. The diversification be￿een asset classes should provide a smoother medium lo long term risk adjusted return and lower volatility. Liquidity It is the expectation of the Trustees that the portfolio will remain invested in liquid assets which are either quoted on a regulated exchange, UCITS (Undertakings for the Collective Investment in Transferable Securiliesl compliant or readily realisable in an orderly manner. Should there be a future reduction in other income streams, the Society would rely on increased income from the portfolio lo support future charitable activities of the Society, and there would then be a change of emphasis between capital growth and income. Benchmarks The Trustees would like lo be provided with two measures from which lo judge the portfolio perforrnan￿. Firstly the MSCI WMA (Morgan Stanley Capitsl International Wealth Management Association) balanced index and secondly UK RPI plus 2.5Yo. 16

Dwusign Envelope ID.. E70B400D-CA454D7F-BBCD-E4CD53DCE207 ROYAL MICROSCOPICAL SOCIETY Report of the Board of Trustees for the year ended 31 December 2024 Perfom7ance & Reporting The investrnenl manager should provide live, online access to the Trustees, provide quarterly valuations and attend the appropriate meetings of the Trustees where required. At least annually the strategic asset allocation should be visited and its suitability confirmed by the Trustees. A review of the long-term performance should be undertaken every five years. Voting The investment manager will exercise, where considered appropriate, voting rights on behalf of the Trustees taking into account the general nature of the Charity. Investment Performance As at the 31 December 2024 the total value of the Society's investments were £4.031,818 {2023: £3.867,1241, the majority of this is held in an Investec managed mixed portfolio and £333.521 represents the value of the Charity's freehold propety let out lo a third party. A breakdown of the investment portfolio can be found within note 14. Reserves Policy The current reserves policy is.. "The reserve will be sufficient lo confront the risks {recorded within the Risk Register) that the Society is exposed to. These include those associated with the charitable aclivilies. In addition to expenditure commitments for the annual meetings and courses, the Society makes a major commitment years in advan￿ of its flagship meeting microscien￿ Microscopy Congress Immcl, so that in any one year the sum approaches £1,000,000. Th8 Society is also exposed to risks associated with being an employer, e.g. legislation and litigation. The Society relies on sources of significant income (the Journal of Microscopy and its investments) that are particularly vulnerable lo external factors. The Society has a risk register and a¢knO￿edge$ the financial risk to the Society from redU￿d andlor curtailed income sources, e.g. Journal of Microscopy, investments and events (fewer people allending conferences as a result of a poor economic climate). The Joumal provides an operating surplus of approximately £398K so if there were to be a loss of revenue from the Journal in the future dLJe to Changes in publication m(xlels for scientificjournals, provision should be made for this additional amount each year from investments to cover the potential loss. The Society's reserves therefore need to be sufficient to allow il lo operate and adapt for a minimum of twenly-foLJr months in the event of cessation of income from these sources and thereafter if il ceased to be financially viable lo meet its commitments to staff. Twenty-four months running costs equate lo around £1.75 million (not including direct costs on activities). Running costs including all direct costs less Joumal income would be approximately £2.562 million. Increasing our Reserves lo Ihirty-six months has been discussed al various Executive meetings. This will continue lo be reviewed at the annual Executive Strategy meeting. In 2024 - 2025 the Society's commitment lo growth - described within ils rolling five-year strategy- will continue with ils ambitious Outreach & Education projects and will continue to draw on some of ils reserves. The rolling strategy also requires us lo make improvements to the building and also the IT and infraslruclure. Plans for the future include marketing the Societies expertise in organising conferences and exhibitions, increase membership, making improvements in the online version of infocus magazine and running of the 100 Microscope Activity Kit loan scheme for the foreseeable future al a cost of approximately £23K per year. The Society's unrestricted funds consist of the accumulated fund and the capital fund. The accumulated fund represents the Society's reserves that have not been assigned lo any other funds. At 31 December 2024, the balance of this fund was £564K12023.' £681 Kl. The capital fund represents the society's interest in investments 17

The cost of investment management is shown as a charge against the capital fund and similady the depreciation cost on freehold propety has been charged to the capital fund. Al 31 December 2024, the balan￿ of this fund was £4.744M12023'. £4.523MI. The Society's designated fLJnds consist of the Building Fund £25.gK {2023.. £20.1 Kl, Outreach Fund £26.2K 12023.. £24.2KI and IT Fund £56.5K 12023.. £55KI. The BLJilding Fund was sel up to fund future repairs, maintenance and improvements to the offices, flat and restaurant. The Outreach Fund was sel up lo support any activities in the area of its Outreach program. The IT Fund was set up to fund future improvements lo IT database. The Society currently has sufficient funds available lo meet the requirements set out in the reserves policy, and proportion of the Investment Portfolio can be made available if required. The unrestricted funds available currently stsnd at £5.417M which exceeds the running costs set out in the reserves policy. The running costs do vary on an annual basis and can increase with the commitment to the organisation of a large conference. For example. the running costs within the reserves policy, prior lo the impact of the ¢ovid-19 pandemic, stood al £3.98M. The Executive Committee is also monitoring increasing the reserves lo 36 months, which is reviewed al the annual Executive Strategy Meeting, as the commitment lo secure a large venue is usually required up to four years in advance. The Society has four restricted funds detailed in Note 19. Publlc Beneflt The Trustees, Annual Report describes the activities undertaken to further the Society's charitable purposes for the public benefit. Particular highlights of the Society's public benefit activities include the provision of the Microscope Activity Kits IMAKS), which are lent lo Primary Schools for a school lemi al a time, free-of-charge, and include microscopes and activities which are linked lo the school curriculum. These kits are booked out up to a year in advance and so far have benefited nearly 200,000 4-11 year old children encouraging them to have an interest in science at an early age. The Society has also supported the logistics and transportation of two tabletop SEMS and X-Ray Microanalysis Equipment lo Secondary Schools around the UK in a scheme which is also supported by the Natural History Museum, Hilachi Scientific, Oxford Instruments and IRIS (The InstitLJle for Research in Schools). The SEM has been loaned lo 26 schools to dale, with three more due this year and those 26 schools have then connected with a further 60 schools, for a total of 86 schools that have been involved in the programme. We have also worked with the Armourers and Brasiers with generous support from the auekett Microscopical Club to be able to offer, throLJgh the Natural History Museum a second SEM donated by Hilachi again. 'We also have 3 MAK'S that are loaned lo evening and weekend STEM groups as well as Community Education groups (Scouts and Girl Guiding) making this figure far greater. Al the other end of the scale the Society organises a wide range of training courses and scientific meetings for research scientists. The courses provide training to scientists lo enable them to get the best possible results from using their microsc£)pes, im8ge analysis software and flow cylometers in their research, in leaching al various Universities. and in Industry. The Scientific Meetings provide a forum for cutting edge science networking and discussion, which attendees take back to their colleagues lo work on and further develop their scientific research. The Society provides bursaries lo enable scientists to attend these meetings. The Trustees have conSide￿d the Charity Commission's requirement in respect of Public Benefit. In their view the charity meets, in full, the criteria to satisfy the lesl. The Trustees, annual report further describes the activities undertaken lo further ils charitable purposes for the public benefit. Plans for the Future General In 2023, Sali Davis was recruited as the Society's new Chief Executive Offi￿r, to replace her predecessor of 40 years, Allison Winlon. Since then, Sali continues lo oversee the strategic and operational activities for the Society. Under Sali's leadership and direction the following new inilialives have been implemented the following.. undertaking a fully comprehensive governance review which has resulted in a refreshed Handbook for the commillees and focussed interest groups that the RMS oversee and provide secretariat for along with a streamlining of the ExecLJtive, Council and Section Chair committees and Board. A new cor)flict of interest and 18

Significant progress has been made on delivery of the Chartered Microscopist and Registered Technician qualifications with all associated Societies and Organisalions such as the Royal Society of Chemisty and Biology, the Institute of Physics all expressing support for this planned offering for members. The RMS Ambassadors programme is also being refreshed with a very different package being offered to those who wish to be part of this scheme. The scheme will be open lo applications from members only and the re-launch has been supported by a student intern, Malika Zahedi. Sali's focus continues lo be ensuring the long term financial viability of the society which is inextricably linked with the performance of its investments, the Journal of Microscopy and its other charitable activities. Strategy Meetings continue to explore the impact and miligale the potential income loss of the anlicipaled move of the Journal tr) open access and ways of increasing income and decreasing expenditure continue to be explored by the Trustees. Sali has hopes that the RMS will meet these challenges by continuing to working more collaboratively with other like minded stakeholders who are also facing similar challenges such as other Royal Societies whose charitable aims and pursuits lie firmly within the scientific sector. As such, three Memorandum of Understandings have been drafted and signed by three other societies which will help secure. foster and encourage greater collaboration with working partners and stakeholders. Generated funds The restaurant will be leased lo the exisling tenanl until 2039 and rent for the reslaurantwill continue lo be charged at the market rale with regular rent reviews. The flat is not rented out through a letting agent, but may be rented on an ad hoc basis and we are currently exploring options to rent out the meeting rooms we have lo generate further income. On-going repairs and maintenance lo the building will continue lo be funded from the designated Building Fund. The Society will ￿ntinUe to explore ways of maximising investment income Iwilhin the boundaries of the Investment Policyl and will work closely with ils investment manager and bankers lo maximise returns on cash holdings. Charitable activities DLJring 2024 we have held a range of both 'in person, and virtual events starting off with the first quarter during which we held the popular International Microscopy Lecture Series IIMLSI along with our regular Expansion Microscopy User GroLJP Meetings, EM-UKI, Cryo Microscopy Course and the Virtual Flow Cytomelry Data Course We continue lo represent all sections of our mieroscopy, imaging and cylometry communities delivering meetings such as an AFM & SPM Meeting, our Virtual Facilities Management Training Course, the Light Microscopy Summer School, Getting the most from your Confocal Course, an EM Course. We have striven lo work more collaboratively this year as well, hosting a Lab-based X-ray Phase Contrast Imaging event with UCL and allending the popular M&M conference in Cleveland, Ohio emc in Copenhagen and attending and sponsoring the Slrathclyde Optical Microscopy Course. We enjoy hosting our usual cohort of long running events such as the ESRIC Super-Resolulion Summer School and the Flow Cytomelry Course. One of our notable successes this year was delivering the Microscopy." Advances, Innovation, Impact meeting which was a one day meeting incorporating the RMS AGM. Attendees and recipients of the RMS Awards were invited lo give short talks on their work and this was met with resounding praise from all who attended. We were pleased lo be able lo offer the dual Frontiers in Biolmaging and Frontiers in Physical Imaging al the latter end of the year, both of which events were met with strong delegate numbers and widespread accolade. Of note in particular, given the plethora of events we were already undertaking was our Suc￿$$fUl bid to host ELMi24 in Liverpool. Over three days this international event combined a heady mix of vibrant conference sessions covering all the lalesl techniques and applicalions in light microscopy. Liverpool will also be the destination for the IMC21 bid which we are acting as PCO for in 2026 We continue lo try lo increase our current membership numbers by keeping subscription rates low, with just a very small increase in rates for 2024 and we are looking al our current benefit package for our membership and our Corporate members.

With the return to more 'in-person' events we will be recruiting new members at our own events, and attending other events to promote both RMS membership and the Society in general. Membership benefits will continue to be reviewed on a regular basis. The quality of the Journal of Microscopy has enabled us to maintain income similar to previous years, though this has started lo reduce. On-line subscriptions will continue to replace hard(x)py subscriptions and the digilized back issues of the Journal continue lo be popular though at a reduced level, but still providing in the short term an additional income stream. Developments in Open Access publishing will continue lo be monitored carefully by the Trustees and Wiley the publishers. We continue to put additional resources into Social Media as il is proving lo be a tool widely used within the scientific community lo communicate more effectively and in a more instantaneous way. Our followers on Facebook, Twiller, Instagram and Linkedln increase steadily each month and this helps us to promote the Society, engage with our members and the wider community.

Our objectives are to obtain reasonable assurance about whether the financial statements as a wFK)le are fr￿ from mater￿1 misstatemenL whether due to fraud or error, and to issue an auditor's report that includes our OFMnK)n. Reasonable assuran￿ is a high level of assuran￿, but is not a guarantee that an audit conducted in a(￿ordan￿ with ISAS IUKI will always detect a material misstatement when il exsts.

Whilst considering how our audit work addressed the detection of irregularities, we also considered the likelihood of detection based on our approach. Irregularities arising from fraud are inherently more difficult lo delecl than those arising from error. Because of the inherent limitations of an audit, there is a risk that we will not delecl all irregularities, including those leading lo 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 lo become aware of instances of non-complian￿. The risk is also greater regarding irregularities occurring due lo fraud rather than error, as fraud involves intentional Con￿alMent, forgery, collusion, omission or misrepresenlalion.

The financial statements have been prepared for the Society as a single entity. The financial statements are denominated in sterling, whid) is the Society's functional currency. and are rounded lo the nearest whole pound. The preparation of finanaal statements in compliance with FRS 102 requires the use of certain critical accounting estimates. It also requires management lo exercise judgement in applying the Society s accounting policies (see note 2}. b) Going concem The Royal Microscopic81 Society has a strong cash position, and the majority of its funds are unrestricted funds. The Society continues lo review ils expenditure during 2024 to reduce the cost base where feasible, which offset the majority of the reduction in income.

Any marf(el valuation of the (x)Ileclion is indeterminable due lo the age and a lack of accurate financial information relating to the individual items making up such a collection. Therefore, no value has been included in the tangible fixed assets included in these financial slalements in relation to this collection. The collection is presently in the care of the History of Science Museum within the University of Oxford. e) Penslons The Society contributes lo a defined contribution pension scheme. The assets are held separately from those of the society in independenuy administered funds. The contributions are charged lo the statement of financial activities on a payable basis. The contribLJtions paid are shown in note 12. fj Fund accountlng The society maintains various types of funds as follows.. General funds are unrestricted funds which are available for use at the discretion of the trustees in furtherance of the objectives of the charity and which have not been designated for other purposes. Designated funds comprise unrestricted funds that have been set aside by the Iruslees for particular purFK)ses. Restricted funds are funds which are to be used in accordance with specific restrictions imposed by donors or which have been raised by the society for particular purposes. g) Income All incoming resources are recognised once the charity has enlillemenl lo the resources, it is probable that the resources will be received and the monetary value of incoming reSoU￿S can be measured wth sufficient reliability. Deferred income represents amounts re￿iVed for future per1(￿S and is released to incoming resources in the period for whith l( has been re￿ived. h) Resources expended Liabilities are recognised as resources expended as soon as there is a legal or constructive obligation committing the society to the expenditure. All expenditure is accounted for on an accruals basis and has been classtfied under headings that aggregate all costs related to the heading. Expenditure on raising funds are those costs involved in attracting voluntary income and those associated with the management of the investment portfolio. Expenditure on charitable activities includes expenditure associated with the production of publications, organisalion of meetings and courses and the processing of grants. Governan￿ costs include those incurred in the governance of the society and its assets and 8re primarily associated with constilulional and stslutory requirements. Support costs represent the costs incurred by staff directly providing support for the production of publications, meetings and other activities that further the charity s objects.

Basic financial instruments are initialty recognised at transaction value and subsequently measures at their settlement value. l) Cash Cash al bank and in hand includes cash and short-term highly liquid investments w(th a short maturity of three months or less from a dale of acquisition or opening of the deposit or similar account. ml Debtors Trad8 and other debtors are recognised al the settlement amount after any trade discount offered. Prepayments are valued al the amount prepaid net of any trade discounts due. n) Creditors Liabilities are recognised when there is an obligation at the balance sheet dale. As a result of a past events, it is likely that a transfer of benefit will be required in setdement. and the amount of the settlement can be estimated reliably. Liabilities are recognised at the amount that the Society anticipates il will pay to sellle the debt. Alternatively, the amount il has re￿iVed as advanced payments for goods or services which the Society MLJSI provide. 2. Judgements In preparing the Financial Statements, trustees are required to make eslimales and assumptions which affect reported income, expenses, assets, liabilities and disclosu￿ of conlingenl assets and liabilities. Use of available information and application of judgement are inherent in the formation of eslimales, together wlh expectations of future events that are believed to be reasonable under the ryrcumslances. Actual results in the future could dtffer from such estimates. There are not considered to be any significant judgements or estimates other than the valuation placed on the heritage assets and freehold property (see belowl. These heritage assets are carried al nil value on the basis that the value of these assets is impossible to estimate, due lo their unique nature. The Society carries its freehold property al fair value, with changes in fair value being recognised in the Statement of Finanoal Activities. The souety engaged independent valuation specialists lo determine fair value at 31 December 2021. Some of the key assumptions used lo determine the fair value ofthese assets are based on the valuer's knowledge and experience of the market and values of similar properties, which could be deemed subjective. In be￿een formal revaluations the Trustees assess the carrying value of the freehold propety. The society's property is mixed-use and an apportionment must be made between Investment Propety and Propety, Plant and Equipment on the basis of square fool used in each activity. There is little eslimalion involved in detemiining the value of accruals and prepayments, as these are mostly based on supplier invoices elc. Depreciation rates are based on 'induslry norms and experien￿ of the lrfe of assets. 3.
