BOS Objectives & Activities Our Mission As the leading voice of orthodontics in the UK we are dedicated to the life.enhancing results that orthodontics delivers. Together with our professional members, we champion the advancement of the specialty through educatlon, advocacy and research. We are driven by excellence in patient care. Charitable Aims To promote the study and practice of orthodontics. To maintain and improve professlonal standards In orthodontics. To encourage research and education In orthodontlcs.

THE BRITISH ORTHODONTIC SOCIETY TRUSTEES. REPORT (CONTINUED) (INCLUDING DIRECTORS. REPORT) FOR THE YEAR ENDED 31 DECEMBER 2024 Activitres Delivery of an education portfolio for the whole orthodontic team including a range of In- person and online education. Development of standards of orthodontic ¢are for professionals to follow. Promotion and funding of research in orthodontics. The charity has paid due regard to the guldance Issued by the Charlty Commlssion In deciding what activities the charity should undertake. Achievements, Performance & Forward Plans Clinical Practice Over the past year, several significant achievements have been made. Meetings have taken place with NHSE and Managed Clinical Networks (MCNS) to dlscuss the implications of the new Provider Selection Regime (PSR} guidance and its relevance to orthodontic commissionin8. In parallel, active support has been glven to the legal case agalnst HMRC In an effort to overturn the decision to remove VAT exemption on orthodontic appliances. Alongside these national-level initiatives. ongoing assistance has contSnued for members with contractual matters, while also responding to queries raised by members of the public. These activities have led to tangible improvements in beneficiaries, circumstances. Members have received regular updates on contractual arrangements and the latest legislation affectlng orthodontlc procurement. In addition, direct support has been offered to the public, helping individuals understand treatment access, NHS eligibility criteria, and standards of care. The impact has also been felt more widely across society. Efforts to raise national awareness of oral health have been delivered through public campaigns and strategic partnerships. Relationships with NHSE and the British Dental A550ciation (BDA) have been further strengthened, ensuring a more coordinated approach to orthodontic provision and advocacy. Nevertheless, challen8es remain. A key priority is ensuring that MCNS make full use of the cornprehensive range of contract tendering options set out In the PSR guidance document. Another challenge lies in reaching all members of the profession to ensure they are,well supported during the next round of orthodontic contract tendering.

THE BRITISH ORTHODONTIC SOCIETY TRUSTEES. REPORT (CONTINUED) (INCLUDING DIRECTORS. REPORT) FOR THE YEAR ENDED 31 DECEMBER 2024 Looking ahead to 2026 and beyond, the focus will be on continuing to influence NHSE policy in relation to orthodontic provision. A major part of thls work wlll involve educating MCNS on the role of the PSR guidance in the forthcoming round of contract tendering. Members will also be supported through the orthodontic reprocurement proces5 With regular update5 provided at BOS events, ensuring they remain fully informed and prepared for future developments. Matt Clover Director of Clinical Practice Education Over the past year, the Society has delivered a wide range of educatlonal opportunitles for all members of the orthodontic team, offered In face-to-face, vlrtual, and hybrid formats. Member5 now also benefit from a virtual learning environment hosted on the Moodle platform and administered by the Royal College of Surgeons of Edinbur8h. This plarform provides access to a variety of CPD activities tailored to different groups: specialty trainees in orthodont5cs (years 1-3) can access the National OrthodontSc Programme, whlle a dedlcated post-CCST area has been developed for ST4-5 trainees. Dental Care Professionals have their own bespoke section, and all members benefit from a general area linked to CPD resources assoclated with the Journal of Orthodontics. A number of targeted initiatives have further enhanced training provision. A national webinar was delivered to specialty trainees and their Clinical and Educational Supervlsor5 to explain the new Orthodontic Specialty Curriculum and assessment methods introduced in September 2024. Core CPD has contlnued to be provlded via Pro-Dental CPD, and collaboration with the British Society of Dental and Maxillofacial Radiology has enabled the delivery of specialist CBCT training. In addition, the Society worked wlth the Training Grades Group to organise a national post-CCST virtual seminar programme, supporting specialty trainees preparing for consultant roles within the NHS. Beyond educatlon, a slgniflcant achievement wa5 the careful packaging and secure storage of the BOS Museum and Archives in a bespoke facility, ensurin8 the preservation of the Society's history. These initiatives have improved circumstances for beneficiaries by enhancing the professional capabilities of members and, in turn, supporting the wider public. The provision of continuing education and CPD opportunities has been central to maintsining high professional standards and improving the quality of patient care.

THE BRITISH ORTHODONTIC SOCIETY TRUSTEES. REPORT (CONTINUED) (INCLUDING DIRECTORS. REPORT) FOR THE YEAR ENDED 31 DECEMBER 2024 The impact has extended beyond immediate beneficiaries. The Society ha5 continued to raise natSonal awareness of oral health through public campaigns and partnerships, while also supporting research into treatment effectiveness, helping to strengthen the evidence base that informs both policy and clinical practice. At the same time, BOS has upheld and promoted ethical standards, transparency, and professionalism across dentistry, reinforcing public trust In the profession. Performance against key indicators has been strong. More than 30 educational events were delivered. with over 85% of attendees rating the content and organisation as excellent or very good. Thirteen active BOSF-funded research projects were supported, representin8 commitments of more than £500,000. In addition, the Journal of Orthodontics achieved a major mllestone in securing its first Impact Factor (1.31, alongside a notable increase Sn submissions from 28 different countries. Looking forward to 2025 and beyond, the Soclety plans to further expand CPD opportunities for the orthodontic team. This will be achieved both through a diverse programme of educational event5 and by continuing to develop the Virtual Learning Environment, ensuring that members across all roles and stages of their careers have access to hi8h-quality, flexible learning. Hemendranath Shah Director of Education External Relations Over the past year, the External Relations team has delivered a number of important achievements. A major milestone was the bulld and launch of the My Mlssing Teeth websSte {www.mymissingteeth.co.uk), designed to educate and inform the public about the condition, which affects one In thlrty people In the UK. Alongside this, the Soclety celebrated its 30th anniversary with a year-long campai8n, BOS @30, which was widely covered and well received by members. Press engagement has been extensive and impactful, securing national and professlonal coverage across a wide range of topics. Notable examples include features in The Guardian on soft foods and jaw development and on "mewing," an article in BDJ In Practice on dental tourism, and coverage of Roz Mcmullan's OBE. The team also secured widespread media attention for the announcement of the new BOS President and Honorary Patron, contributed expert advice to Sussex Express on jaw and dental health, partnered with Kidscape for Anti-Bullying Week, and supported the drafting of a joint letter to the Health Secretary, Wes Streeting, and Chief Dental Officer for England. Jason Wong.

THE BRITISH ORTHODONTIC SOCIETY TRUSTEES. REPORT (CONTINUED) (INCLUDING DIRECTORS. REPORT) FOR THE YEAR ENDED 31 DECEMBER 2024 Support was also provided to BOS educational events, enabling hybrid delivery options for delegates both onsite and onllne. A new co-hosted event with 32Co was successfully launched in collaboration with the office and events team, providing a potential blueprint for future InitiatSves. The ongoing @KeepGBSmiling campaign continued to promote healthy eating and oral hygiene, while the team also assumed responsibility for the commercial aspects of BOS magazines and the Journol of Orthodontics. Furthermore, the Society maintained a visible presence at major industry events, including BDIA, Dentistry Show, and Dentistry Show London. by providing speakers and hosting stands. These efforts have brought clear improvements to members, experiences. The Members, Area of the BOS website was upgraded, issues with the online shop were resolved, and the Find a Treatment function was reinstated. Participation in careers fairs enhanced the visibility of orthodontics as a career choice, fostering early engagement with the profession. The BOS Foundation IBOSF) also benefited from new online donation pages, allowing members to make one-off or ongoing contributions. while additional guidance and support were provided to the new Editor of BOS News, Arti Hlndocha. The impact has also been felt more widely. The team's proactive liaison with both consumer and professional press has provided expert insight, commentary, and, when necessary, refutations of misinformation about orthodontics. The launch of the My Missing Teeth website has created a valuable new resource for the public. while national campalgns and partnerships have continued to raise awareness of oral health and the importance of orthodontic care. Performance metrics highlight the strength of these achievements. The 30th Anniversary campaign secured multiple national media placements and extensive professional coverage. Public engagement has continued through campaigns, events, and targeted university outreach. From October 2024 to August 2025, the BOS website attracted more than 68,000 users, with over 26,000 views of the "Your Jaw Surgery" section and more than 2,200 users accessing the Members, Area and professional pa8es. Social media presence also grew, with combined following of 6,118 across all platforms and private member 8roups reaching 5S6 participants. Linkedln generated around 4,000 impressions per month, Facebook achieved approximately 2,500 monthly views, and Instagram our highest-engagement platform reached 13,500 views per month. All channels continue to show healthy growth. There have, however, been challenges. The situation In Gaza generated strong opinions among members, and as a registered charity the Society was limited in what it could publicly say. Another ongoing challenge has been maintaining member engagement by providing content and services that encourage both retention and recruitment. Looking ahead to 2025 and beyond, the External Relations team will contribute actively to

THE BRITISH ORTHODONTIC SOCIETY TRUSTEES. REPORT (CONTINUED) (INCLUDING DIRECTORS. REPORT) FOR THE YEAR ENDED 31 DECEMBER 2024 the Membership Working Party, helping to communicate new and improved benefits to both existing and potential members. Work will also continue within the Commercial Working Party to explore ways of collaborating effectively with industry partners for the benefit of both the membership and the sector as a whole. The Society will maintain its presence at major dental events and exhibitions, providing speakers and encouraging new membership and attendance at BOS events. Press engagement with both professional and consumer media will continue to raise the profile of orthodontics, the Society, and the value of its offering. Finally, collaboration with the 80S Foundation will focus on developing an effective strategy to increase donations, whether through one-off contributions, on80ing support, or legacy giving. Hayley Llandro and Anjili Patel Current and Former Director of External Relations Clinical Governance Over the past year, the Governance Directorate has delivered a broad range of work across its core areas of audit, publications, ethics, and clinical effectiveness. Audit The directorate, under the leadership of Mariyah Nazir, Chair of Audit, has continued to recelve a steady number of requests for surveys. The ability to seek the vlews of mernbers Is of great value to the Society, providing insight into clinical practice, professional perspectlves, and workforce trends. At the same tlme, care Is taken to avold over-surveyin8, which can lead to fati8ue and reduced response rates. Striking the rlght balance remalns a priority. Recent surveys have explored a wide range of important topics, including: clinical declsion- making in radiographic assessment of ectopic teeth and the use of CBCT; health advocacy in orthodontics; diversity and leadership wlthin the profession; functlonal appllance use by UK orthodontists; patient-initiated follow-up (PIFU); job satisfaction among orthodontic therapists. the impact of MRI on orthodontics. clinician experiences of duty of candour. and national approaches to clinical photography in hospital orthodontic departments. These projects demonstrate both the breadth and depth of issues explored through Bos-led audit. The Society is grateful to Mariyah for the excellent work she continues to provide in this vital area. Publlcatlons The directorate also encompasses publications, led by Chair Sameer Patel. Significant progress has been made in updating and expanding BOS advice and information leaflet5, ensuring that both members and the publlc have access to reliable, high-quality 8uidance.

THE BRITISH ORTHODONTIC SOCIETY TRUSTEES. REPORT (CONTINUED) (INCLUDING DIRECTORS. REPORT) FOR THE YEAR ENDED 31 DECEMBER 2024 These resources are available in both digital and printed formats, with a structured publication programme developed in partnership with the BOS News team to promote awareness and accessibility. The advlce leaflets, authored and updated by BOS members, are designed to support professional practice while also benefiting patients and, in some cases, reaching a wider audlence. Recent work has focused on ensuring consistency between member-facing and patient-facing guidance, particularly around issues such as written consent. While defence socletles advise that a written treatment plan Is not a strlct requirement for orthodontics, the Society's position is that such a plan is often helpful. Efforts have also been made to revlew the readabllity and accessibility of publlcatbons to ensure they meet the needs of all audiences. Ethlcs The governance directorate further includes ethlcs, led by Chair Nicky Stanford. On behalf of BOS, Nicky attended four meetings with the GDC regarding their new Scope of Practice 8uldance. The Society was successful in securing the inclusion of all its recommendations, and the final guidance is expected to be published later this year. Key outcomes include explicit clarificatlon of the orthodontlc therapist scope of practSce, with confirmation that procedures involving the removal of enamel, such as interproximal reduction (IPR), are outside their remlt. In addition, it was conflrmed that all orthodontlc procedures, includin8 IPR for orthodontic purposes, are outside the scope of practice for dental therapists. In addition, BOS contrlbuted to a GDC round table on thelr forthcomlng consultation regarding a new Framework of Professionalism. This framework will be supported by material from speciallst societies, enabling the GDC to illustrate how principles and professional guidance apply to different clinical situations and contexts. Cllnical Effectiveness Bulletin The directorate also oversee5 the Cllnical Effectivene55 Bulletin (CEB}. After a period of valued service, Robert Smyth has completed his term as editor. His contribution, particularly the development of searchable publlcations on the BOS website, will leave a lasting le8acy. The Society extends its thanks to Robert for his excellent work and dedication. The winners of the CEB prize will be formally announced at the BOC.

BOS research raises national awareness of the value not only of orthodontics to health and wellbeing but also the value of oral health and how orthodontics contributes to overall health. Through public campaigns and partnerships such as "Keep Britain Smiling" there ha5 been increased engagement of the public raising their awareness of the benefit5 of orthodontics, the role that orthodontic treatment plays In overall oral and general health. Increased emphasis on person centred care and inviting feedback from those who have received orthodontic treatment with this being used to promote the benefits. 4.

THE BRITISH ORTHODONTIC SOCIETY TRUSTEES. REPORT (CONTINUED) (INCLUDING DIRECTORS. REPORT) FOR THE YEAR ENDED 31 DECEMBER 2024 mitigating activities are encompassed in the BOS / BOSF 2024 research strategy and action plan. It has been agreed by the Board that research pump-primers are now the preferred way to utilise limited resources & the immediate plan is that fundraising activities will generate the "relatively small" amounts of matched funding to cover these projects. In 2024 the BOS Student Technician Award was not awarded, and there were no entries for the Laurence Usiskin Student Elective Award. It is important that support for and uptake of all BOS award5 is prioritised. Environmental sustainability now and in the future of orthodontic treatment provision has been highllghted In 2024, and will be an ongoing challenge with attention to clinical procedures, materials, digital imaging and remote monitoring as potential mitigating factors. 6. Plans for 202$ and be ond Develop and implement the new BOS / BOSF research strategy approved at the December 2024 BOS Board meeting, including initiatives at a national and/or international level to raise funding for research, coordinate orthodontic research, promote person centred evidence based treatment and improve long term sustainability. Specifically thi5 will include actlons on the followlng: Continue to drive the quest for increased BOS Membershlp by tailoring activities to the needs of our members in the various BOS sub-groups. Encompass the interests of the wlder orthodontic which includes our nurses, theraplsts, hy8enlsts and technlclans as well as the dentists with a special interest in Orthodontics, Optlmise communlcation and collaborative activities with our corporate members, sponsors and other stakeholders such as the Royal Colleges.

THE BRITISH ORTHODONTIC SOCIETY TRUSTEES. REPORT (CONTINUED) (INCLUDING DIRECTORS. REPORT) FOR THE YEAR ENDED 31 DECEMBER 2024 Revamp future BOC events to ensure that we embrace our sponsors, past members / retired members and past BOS Offlce Holders. Make it attractive and also easy for our BOS members, but also members of the public to make donations to the 8OSF Acknowledge and highlight the ongoing success of the Journal of Orthodontlc5 (JO and showcase ongoing BOSF funded research and our Scholarship and Award wlnners. Seek programme grants and scholarshlp grants on some of the big issues facing DentSstry and Orthodontlcs such as SUStalnability, oral health, integratlon with general health and wellbeing, interceptive orthodontics etc in partnerships with major International research funders. Peter Mossey Director of Research Professional Development In 2024, the British Orthodontic Conference (BOC) stood out as one of the yearfs major achievements. The event was well received by delegates and drew positive reviews, though it unfortunately did not break even financially and recorded a loss. Building on this, work began to launch the 2025 conference at a new venue, ICC Wales. Alongside these efforts, the team focused on reduclng both its size and expenses, strengthening its partnership with the new Marketing and PR contractor, Positive Communications, and streamlining the conference platform through the use of CVENT. 13-

THE BRITISH ORTHODONTIC SOCIETY TRUSTEES. REPORT (CONTINUED) (INCLUDING DIRECTORS. REPORT) FOR THE YEAR ENDED 31 DECEMBER 2024 These actions translated into direct improvements for beneficiaries. Delegates experienced a smoother and more engaging conference both in the lead-up to and during the event. At the same time, work was undertaken to secure the long-term future of the BOC for member5, the Society, and the wider speciality, ensuring it continues to serve as a benchmark for orthodontic education and events. The benefits extended to society more broadly. The BOC remains one of the most visible and important aspects of the BOS'S work, carrying significant profile and brand value across the profession. Membership of the BOS offers many advantages, but access to the BOC continues to be one of the strongest elements of the Society's value proposition. The conference also plays a vital role in maintaining and strengthening relationships with the wider trade and other professional organisations. However, challenges remaln. Like all large-scale events, the BOC faces pressures linked to delegate numbers and discretionary spending, both of which are influenced by wider economic conditions largely outside the Society's control. In response, several measures have been introduced to mitigate these risks. These include enhancing the trade sponsorship experience to secure stronger revenues, streamlining the BOC team, and introducing new or improved conference features. Other strategies include refining benefit packages for speakers, consolidating the conference timetable to reduce overhead costs, limiting expenditure on discretionary elements such as social events, and considering smaller-scale events in proportion to likely audience sizes in the future. Looking ahead to 2025 and beyond, the Society remains committed to running the BOC but with an increased focus on aligning the scale, scope, and style of the event with both audience needs and the financial realities facing the BOS. Thi5 may include explorin8 the use of mid-size hotel conference venue5 in place of larger-capacity centres. Strengthenin8 commercial and professional partnerships will be a key priority, both to reduce costs and to add value and new features for delegates. Finally, there are plans to consolidate BOS events into single timeframes and locations, reducing overheads while enhancing the value delivered to delegates.

THE BRITISH ORTHODONTIC SOCIETY TRUSTEES. REPORT (CONTINUED) (INCLUDING DIRECTORS. REPORT) FOR THE YEAR ENDED 31 DECEMBER 2024 4. Financial Review Market Review of 2024 Global financial markets performed strongly overall in 2024. Over the year, the broader global stock market rose by 20.13%. The US stock market was the driving force behind global gains, returning 26.77%. This was largely due to higher economic growth rates and a greater weighting to the best performing sectors, in particular technology. The FTSE 100 Index ended 2024 in positive territory. rising by 5.7% over the year to notch up a fourth consecutive year of positive gains, while the FTSE 250 Index rose by 4.7% over the year. The Bank of England lowered its base rate from 5.25% to 4.75%. The outcome of the US election, the UK budget and persistent inflationary pressures have stoked expectations that interest rates will fall more slowly than previously hoped. The MSCI UK returned a respectable 9.4% in 2024, underperforming the US but outperforming continental peers as the MSCI Europe ex UK returned 2.7%. Softer export demand due to China's slowdown and polltlcal Instability In Germany and France the Eurozone's two largest economies - weighed on performance. The pound ended the year 1.7% lower at usSI.26, towards the lower end of Its 12-month range after the US dollar strengthened significantly following the US election. Investments Policy & Performance The Trustees are empowered to Invest the Surplus funds of the Society as they see fit. In practice, the Trustees have appolnted Qullter Chevlot as the Society's investment managers, to administer and advise on the Society's investment portFolio and all surplus funds are Invested through them. The investment managers are under instructions to grow the portfolio to a sufficient size to be in the position to fund scholarships and larger research studies. There are no restrictions placed by the Trustees on the nature of investments to be held, but the investment managers are expected to balance the type of investments to achieve a medium risk profile. The Trustees discuss and decide annually on the level of investment once the free reserves of the Society are confirmed following the audit of the financial statements. 15-

THE BRITISH ORTHODONTIC SOCIETY TRUSTEES. REPORT (CONTINUED) {INCLUDING DIRECTORS. REPORT) FOR THE YEAR ENDED 31 DECEMBER 2024 Quilter Cheviot ("QC") run a charity specific fund, namely the Global Income and Growth Fund for Charities. After a positive 2023 which saw an Il% increase, the fund generated another positive return of just over 9% in 2024, putting it into the 2nd quartile. The GBP Allocation 60-80% Equity was also at 9%. Risk Return Overall, gains on the Society's investments amounted to £83,444.32, a small decrease compared to the £92,659.00 gain achieved In 2023. We continue to monitor the fund's performance on a regular basls. We speak and meet regularly with the relatlonshlp and portfolio managers at Quilter Cheviot to ensure the Society's best financial interests are being maintained. As of August 2025, the BOS holds £1.282M of liquid assets whlch is suffi'cient to continue Its charitable activities into 2025 and the years beyond. A total of £200,000 was wlthdrawn from the main investment fund in Oecember 2024, and a further £IOO,000 was withdrawn from the Foundation Fund. This helped support the funding of ongoing BOS and BOSF research and provided the Soclety with sufficient cash flow/workin8 capital until March 2025 when the next year's membership fees were recelved. Going concern The Treasurer contlnues to work closely with the COO and the flnance team to manage both the day-to-day and longer-term financial position of the charity. The Trustees remain confident that the charitable company will continue in operational existence for the foreseeable future and be able to meet all of its financial obligations as they fall due for a period of at least twelve months from the date of approval of these financial statements. Based on the charitable company's forecasts and action plans. the Trustees consider it is appropriate for the financial statements to be prepared on the going concern basis. The financial statements do not Include any adjustments that would result should the going concern basis of preparath'on not be appropriate. In the event that this basi5 is not appropriate provisions may be required and assets may need to be written down to thelr recoverable amount 16-

THE BRITISH ORTHODONTIC SOCIETY TRUSTEES. REPORT (CONTINUED) {INCLUDING DIRECTORS. REPORT) FOR THE YEAR ENDED 31 DECEMBER 2024 Reserves Pol icy In 2021 The Trustees agreed that unrestricted funds not committed or Invested in tanglble fixed assets ("the free reserves") should not fall below £500,000. The Trustees maintain this figure remains appropriate to enable the current actr'vitles of the charity to contlnue, even If unanticipated events resulted in expenditure that had not been budgeted for. At 31 December 2024 the Soclety had free reserves of £970,718 which Is £470,718 more than the reserrfes policy. In addition to unrestricted funds, at 310ecember 2024, the charltable company also held restricted reserves totalling £109,439. The Trustees are aware that a withdrawal of free reserves is likely to be needed in the final quarter of 2025. This will bring the total below the reserves policy of £500,000. The Board is taking this matter seriously and is working on a recovery plan to rebuild reserve5, including the management of future spending, implementing new fundraising initiatives, adjusting the operating budget and recapitalising the balance sheet. No timeframe has yet been set for reserves to be returned to the target level, but the issue remains a high priority on the Society's Risk Register. Risk and Corporate Governance Matters The Society places a high value on risk management, with a focu5 on identifylng potentlal risks that may compromise the ability to fulfil our key aims, and then putting in place approaches to mitigate these risks. The risks to which the Society15 exposed are reassessed and reviewed by the Trustees on a regular basis at each of the 4 board meetings per year. Individual Trustees are given an area of risk management to keep under review, but all Trustees are involved in updating the linal risk register. A complete risk assessment is undertaken on a yearly basis. This updates the previous year's risk assessment and adds to or amends any risk issues. If a new risk factor is identified during the yearly cycle. then the Trustees responsible for the appropriate area of risk management will Investigate, make recommendations, and actlon any agreed strategy to mitigate that risk. The risk register is maintained by the Honorary Secretary. -17-
