Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 4 Chairman’s statement Results and dividend The net asset value (NAV) per share at 31 March 2026 was 85.1 pence compared with 90.0 pence as at 31 March 2025. The total return per share for the year was minus 0.6 pence (2025: 4.8 pence). The target for the annual dividend yield continues to be set at 4.5% of the opening NAV per share. Having already declared an interim dividend of 2.0 pence per share which was paid in January 2026, the Directors now propose a final dividend of 2.5 pence. These payments totalling 4.5 pence (2025: 4.5 pence) are equivalent to 5.0% of the opening NAV (2025: 5.0%). The proposed final dividend will, subject to approval by shareholders at the Annual General Meeting (AGM), be paid on 4 September 2026. Our NAV per share grew consistently for the first nine months of the financial year, however market volatility in the quarter to March 2026 resulted in a reduction of our NAV. This volatility was caused by concerns over the impact of AI on software company valuations, and uncertainty from rising oil prices and global conflict. Although private market transactions have been less affected, quoted company valuations fell in February and March 2026, and we have taken this into account when striking the 31 March 2026 valuation of the portfolio. For example, The Beauty Tech Group, a listed company that is our second largest holding, was trading below its initial public offering (IPO) price at our year end, resulting in a fall in valuation of £0.6 million.

We continued to realise the Company’s mature portfolio acquired under the previous VCT rules with the remaining investments now totalling £6.6 million (31 March 2025: £9.4 million). Six exits were made during the year, including Idox, which was sold for net proceeds of £3.1 million compared to an original cost of £0.5 million, a 5.8x return. During the period The Beauty Tech Group (previously Project Glow Topco) completed its IPO on the London Stock Exchange. As part of the transaction, we realised 30% of our holding, generating £2.3 million which was a 5.8x return on our original investment. James Ferguson Chairman The Beauty Tech Group successfully completed its IPO on the London Stock Exchange

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 5 Share offers and liquidity In April 2025, gross proceeds of £6.0 million were received from the fully subscribed 2024/25 share offer as 6,596,320 new ordinary shares were issued. The Board also announced the successful subscription of its 2025/26 share offer, which amounted to £30 million. In relation to this offer, an interim allotment of 12,754,862 new ordinary shares was issued in November 2025, generating £11.8 million in gross proceeds, and 20,180,102 new ordinary shares were issued in April 2026, yielding gross proceeds of £18.2 million. The Board continues to monitor liquidity carefully and plans to raise up to £10 million of new capital in the 2026/27 tax year. Further details will be provided in due course. Our dividend investment scheme continues to operate. This enables shareholders to invest their dividends in new ordinary shares free of dealing costs and with the benefit of the tax reliefs available on new VCT share subscriptions. Instructions on how to join the scheme are included within the dividend section of our website, which can be found here: mercia.co.uk/vcts/n3vct/. During the year around 11% of total dividends were reinvested by shareholders. We have maintained our policy of being willing to buy back the Company’s shares in the market when necessary in order to maintain liquidity, at a 5% discount to NAV. During the year, a total of 7,096,426 shares were repurchased for cancellation, equivalent to approximately 4.9% of the opening share capital. Responsible investment The Company’s approach to Environmental, Social and Governance (ESG) responsibilities is set out on pages 31 to 33. The Board Chris Fleetwood and Tim Levett will retire from the Board at the Annual General Meeting. Both Chris and Tim have served on the Board since the Company’s incorporation and have made outstanding contributions to the development and success of the Company over the course of their tenure. Chris has been a very effective leader of the Audit & Risk Committee and Tim has stewarded the Company through changes in VCT Rules and a change in Manager. On behalf of the Board, I would like to thank them both for their insight, experience and dedication to the Company. As part of the Board’s succession planning, David Ovens and Jamie Younger joined the Board as non-executive directors in April 2025 and February 2026 respectively. David has 30 years’ experience of investment and is currently Joint Managing Director of Archangel Investors. Jamie is an audit and business advisory partner in Saffery LLP. He will take over from Chris as Chairman of the Audit & Risk Committee. VCT legislation and qualifying status The Government has increased the amount that VCT-qualifying companies can raise. Annual investment limits were doubled to £10 million (£20 million for knowledge-intensive companies) and lifetime limits rose to £24 million (£40 million for knowledge-intensive companies), with the stated aim of widening the pool of businesses the scheme can support. With effect from 6 April 2026, income tax relief on new VCT subscriptions was reduced from 30% to 20% – the first change to the rate in nearly two decades. The Board is disappointed by this reduction, which it believes runs counter to the Government’s stated commitment to support early-stage UK businesses. In anticipation of a more challenging fundraising environment for VCTs, and to ensure the Company retains the capacity to meet demand for early-stage investment capital, we extended our 2025/26 offer to raise an additional £10 million. We have continued to meet the stringent and complex qualifying conditions laid down by HM Revenue & Customs for maintaining our approval as a VCT. The Manager monitors the position closely and reports regularly to the Board. Philip Hare & Associates LLP has continued to act as independent adviser to the Company on VCT taxation matters. Investment activity has remained strong, with £6.8 million of capital provided to four new venture capital investments and £9.0 million of follow-on capital invested into the existing portfolio

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 11 Investment Manager’s review Overview of the year The UK venture capital market continued its recovery during the year to 31 March 2026, building on the stabilisation that followed the sharp correction from the 2021–22 funding peak. Total VC investment in UK businesses rebounded strongly in 2025, with year-on-year growth driven by renewed investor confidence, a more settled interest rate environment and sustained deal flow across the early and growth stages. For the early-stage market in which the Company operates, conditions remained constructive. Seed-stage activity was robust, regional ecosystems outside London continued to develop, and the pipeline of new company formation remained healthy. Exit routes were more active than in the preceding two years, with trade sales and secondary transactions providing liquidity for investors. At the same time, the market for later- stage and scale-up capital remained tighter, reinforcing the structural importance of patient, early-stage investors such as VCTs in supporting UK businesses through their formative growth phases. Against this backdrop, the Company remained an active investor throughout the year. Four new venture capital investments were completed and follow-on funding was provided to 18 existing portfolio companies, reflecting the increasing proportion of earlier-stage holdings that require multiple rounds of growth capital to realise their potential. At 31 March 2026 the portfolio comprised 60 companies with an aggregate value of £99.3 million. The diversity of the portfolio, spanning technology, health tech and business services, and spread across the UK’s regional innovation hubs, positions the Company well to benefit from the recovery in early- stage deal flow and exit activity described above. The sections that follow set out the portfolio’s performance in more detail. Table 2: Venture capital portfolio cash flow Year ended 31 March New investment £000 Disposal proceeds £000 Net cash inflow/ (outflow) £000 2022 14,730 24,791 10,061 2023 16,208 15,447 (761) 2024 15,098 12,428 (2,670) 2025 14,881 8,326 (6,555) 2026 15,821 9,714 (6,107) Total 76,738 70,706 (6,032) Investments in the year During the year ended 31 March 2026, four new venture capital investments were completed at a cost of £6.8 million and additional funding totalling £9.0 million was invested in 18 existing portfolio companies, by way of follow-on funding rounds. The proportion of follow- on investments is increasing in line with the evolution of the portfolio to earlier stage companies, which often require multiple rounds of growth finance to realise their potential. 7% by value of the portfolio is represented by management buy-out and growth capital investments acquired prior to November 2015 when the VCT rules were amended to promote earlier stage investment. A summary of the venture capital holdings at 31 March 2026 is given on pages 15 to 17, with information on the fifteen largest investments on pages 18 to 22.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 14 Portfolio The venture capital investment portfolio comprised 60 portfolio companies and was valued at £99.3 million as at 31 March 2026. Approximately half of the portfolio (51%) was invested in companies operating in the areas of Software & AI, followed by Consumer at 22% and Health & Life Sciences sectors at 19%. Further details of the composition of the portfolio are shown at pages 7 and 10.

Liquid cash balances are conservatively managed to take minimal risk, and are held with the Company’s banking partners and in a money market liquidity fund managed by BlackRock. Outlook The macroeconomic backdrop as we enter the new financial year remains mixed. UK GDP growth is forecast to be low once more for 2026, constrained by subdued business confidence and ongoing global uncertainty, including geopolitical tensions and the impact of US trade tariff policy on international supply chains. Once the Bank of England is able to reduce interest rates from their current level, financing conditions should ease for businesses and gradually support private market valuations. While the late-March volatility in quoted markets, driven in part by investor sentiment around AI and software company valuations, affected the carrying value of some holdings at our year end, a number of these have since recovered, and we do not regard this as indicative of a structural deterioration in the portfolio. For the early-stage technology and growth businesses in which the Company invests, the underlying environment remains encouraging. Demand for innovative, capital-efficient businesses continues to grow across the sectors in which the portfolio is concentrated, and the UK’s position as Europe’s leading hub for AI, deep tech and health tech investment provides a supportive backdrop for exit activity over the medium term. The Company’s cash and cash equivalents position of £34.9 million at 31 March 2026 provides significant capacity to support existing portfolio companies through follow-on rounds and to selectively deploy capital into new opportunities as they arise. We remain confident in the long-term prospects of the portfolio. We will continue to apply a disciplined approach to new investment, focusing on high-quality companies with credible paths to profitability, while working actively with existing holdings to build value ahead of future realisations. The Company is well-positioned to meet its objective of providing shareholders with attractive long-term tax-free returns, and we look forward to reporting on further progress in the year ahead.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 23 Shareholder information The Company Northern 3 VCT PLC is a Venture Capital Trust (VCT) which has been listed on the London Stock Exchange since September 2001. The Company invests mainly in unquoted venture capital holdings, with its remaining assets invested in a portfolio of quoted investments, money market funds and bank deposits. Northern 3 VCT PLC is managed by Mercia Fund Management Limited (Mercia), a wholly owned subsidiary of Mercia Asset Management PLC (MAM). MAM is a specialist alternative asset manager with over 15 years’ experience of providing capital to high-growth UK SMEs, meeting a large, growing and under-served need for long-term investment capital. MAM offers high-growth UK SMEs a complete capital solution including private equity, debt, seed and venture capital (the latter category accounting for the majority of its investment activity). In being managed by Mercia, the VCTs have the opportunity to co-invest alongside MAM’s own funds, or other funds managed by MAM and its subsidiaries, that are able to provide replacement capital and invest without the restrictions of the VCT Rules. Mercia also acts as adviser to Northern Venture Trust PLC and manager of Northern 2 VCT PLC, in addition to various other investment funds. The Company, Northern Venture Trust PLC and Northern 2 VCT PLC are generally known in the market as the Northern VCTs and are the only VCTs which Mercia manages or advises. Mercia Asset Management PLC is quoted on AIM. Northern 3 VCT PLC is a member of the Association of Investment Companies (AIC). Venture Capital Trusts Venture Capital Trusts (VCTs) were introduced in the November 1994 Budget and are governed by the Income Tax Act 2007. Their purpose is to encourage investment by private individuals into small, unquoted UK trading companies through a range of tax incentives. As at the date of this report, the principal tax benefits available to eligible investors include: • income tax relief at up to 20% on new subscriptions of up to £200,000 per tax year, provided the shares are held for at least five years; • exemption from income tax on dividends paid by VCTs (such dividends may include the VCT’s capital gains as well as its income); and • exemption from capital gains tax on disposals of shares in VCTs. To maintain approved status, a VCT must comply on an ongoing basis with the requirements of Section 274 of the Income Tax Act 2007. In particular at least 80% by value of its investments in qualifying holdings, of which at least 70% must comprise eligible shares. For this purpose a ‘qualifying holding’ is an investment in new shares or securities of an unquoted company (which may however be quoted on AIM) which has a permanent establishment in the UK, is carrying on a qualifying trade, and whose gross assets and number of employees at the time of investment do not exceed prescribed limits. The definition of ‘qualifying trade’ excludes certain activities such as property investment and development, financial services and asset leasing. The current limits for qualifying companies include: • a lifetime funding limit of £24 million (£40 million for ‘knowledge- intensive’ companies); • gross asset limits of £30 million pre-investment and £35 million post- investment; and • an annual fundraising limit of £10 million (£20 million for ‘knowledge- intensive’ companies). In addition, VCTs must comply with the principles-based ‘risk-to-capital’ condition and are subject to investment deployment requirements, including investing at least 30% of new funds in qualifying holdings within 12 months.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 24 Failure to meet the qualifying conditions could result in the loss of VCT approved status. Recent legislative developments: The VCT regime has been subject to a number of reforms in recent years, including: • the introduction of the ‘risk-to-capital’ condition and enhanced investment requirements under the Finance Act 2018; • the extension of the VCT sunset clause to 6 April 2035 under the Finance Act 2024; and • changes effective from 6 April 2026, including a reduction in income tax relief from 30% to 20% and increases to company size and funding limits. Maintenance of VCT qualifying status The Directors believe that the Company has at all times since inception complied with the VCT qualifying conditions laid down by HM Revenue & Customs. Corporate objective The Company’s objective is to provide long-term tax-free returns to investors through a combination of dividend yield and capital growth, by investing primarily in unquoted UK businesses which meet the Manager’s key criteria of good growth potential, strong management and potential to generate cash in the medium to long term. Investment policy The Company’s investment policy has been designed to enable the Company to achieve its objective whilst complying with the qualifying conditions set out in the VCT rules, as amended by HM Government from time to time. The Directors intend that the long-term disposition of the Company’s assets will be approximately 80% in a portfolio of VCT-qualifying unquoted and AIM-quoted investments and 20% in other investments selected with a view to producing an enhanced return while avoiding undue capital volatility, to provide a reserve of liquidity which will maximise the Company’s flexibility as to the timing of investment acquisitions and disposals, dividend payments and share buy-backs. Within the VCT-qualifying portfolio, investments will be structured using various investment instruments, including ordinary and preference shares, loan stocks and convertible securities, to achieve an appropriate balance of income and capital growth. The selection of new investments will necessarily have regard to the VCT rules, which are designed to focus investment on earlier stage development capital opportunities. The portfolio will be diversified by investing in a broad range of VCT- qualifying industry sectors and by holding investments in companies at different stages of maturity in the corporate development cycle. The normal investment holding period is expected to be in the range from three to ten years. No single investment will normally represent in excess of 3% of the Company’s total assets at the time of initial investment. As investments are held with a view to long-term capital growth as well as income, it is possible that individual holdings may grow in value to the point where they represent a significantly higher proportion of total assets prior to a realisation opportunity being available. Investments will normally be made using the Company’s equity shareholders’ funds and it is not intended that the Company will take on any long-term borrowings. Valuation policy Unquoted investments are valued in accordance with the accounting policy set out on page 68, which follows the International Private Equity and Venture Capital Valuation (IPEV) guidelines, being the industry accepted best practice. Where valuations are based on company earnings, audited historic results will be taken into account along with more recent unaudited information and projections where these are considered sufficiently reliable. For investments in earlier stage businesses, where a material arm’s length transaction has recently been concluded, this is usually taken as the starting point for fair value, and subsequently tested and recalibrated to reflect changes in market conditions or company specific performance. Performance is typically considered using a range of metrics such as annual recurring revenue, EBITDA, milestones achieved, customer wins, cash runway and budget accuracy. Provision against cost is made where an investment is under-performing significantly. Shareholder information continued

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 25 Investment Manager Mercia Fund Management Limited (Mercia) acts as Investment Manager and has done so since the Company consented to the novation of its existing investment management agreement from NVM Private Equity LLP (NVM) effective on 23 December 2019. The Board’s Management Engagement Committee reviews the terms of Mercia’s appointment as Manager on a regular basis. Further information about the terms of the management agreement with Mercia and the remuneration payable to Mercia is set out in the Directors’ Report on pages 40 to 41 and in Note 3 to the financial statements. Share price The Company’s share price is carried daily in the Financial Times and the Daily Telegraph. A range of shareholder information is provided on the internet at https://northern-vcts.cityhub.uk.com/login by the Company’s registrar, The City Partnership (UK) Limited, including details of shareholdings, indicative share prices and information on recent dividends (see page 88 for contact details for The City Partnership (UK) Limited). Share price information can also be obtained via the Company’s website. Dividend investment scheme The Company operates a dividend investment scheme, giving shareholders the option of investing their dividends in new ordinary shares in the Company with the benefit of the tax reliefs currently available to VCT subscribers. Instructions on how to join the scheme are included within the dividend section of our website, which can be found here: mercia.co.uk/vcts/n3vct/. Electronic communications The Company continues to provide the option to shareholders to receive communications from the Company electronically rather than by paper copy. Shareholders who wish to change their preferences should visit the Hub (https://northern-vcts.cityhub.uk.com/login (operated by the Company’s registrar, The City Partnership (UK) Limited)), and select their preferred method of delivery of company communications. Alternatively, shareholders may contact the registrar directly to confirm their communication preference using the details on page 88. Co-investment arrangements The Company operates within a co-investment and allocation policy that applies to all funds managed by the Mercia group. Under the terms of this policy, where an investment opportunity is VCT qualifying and the funding requirement is in excess of £3 million, the Company and the other VCTs managed by Mercia are the preferred lead investors. For these opportunities the Company is entitled to participate pro rata to net assets alongside the other VCT funds managed by Mercia; save where the investment opportunity is located in the West or East Midlands, Yorkshire, Humberside, Teesside or the North East, where minimum syndication requirements mean that certain other funds managed by Mercia can participate in the funding round alongside the Northern VCTs; with an allocation in proportion to each fund’s relative net asset value. Where the funding round for a new opportunity is under £3 million the VCTs will not be the lead investors; but if any such deal is in excess of £2.5 million, the Northern VCT funds have the right to participate at a de minimis level of £0.5 million. In relation to follow-on rounds of investment where the Company and other Northern VCTs are existing investors, the Company, alongside the other Northern VCT funds, shall have priority to determine how much they wish to invest, with no requirement to offer such investment opportunities to the other funds managed or advised by the Mercia group (although they are free to do so if so determined by the Manager). Under a co-investment scheme, members of the VCT investment team and certain key Mercia executives are required to invest personally alongside the funds in each VCT-qualifying investment on a predetermined basis.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 26 Section 172 of the Companies Act 2006 requires a Director to promote the success of the Company. In doing this they must act in the way that they consider, in good faith, would be most likely to promote the success of the Company for the benefit of its members as a whole. In doing this the Directors are required to have a regard, amongst other matters, to the: • likely consequences of any decisions in the long term • interests of the Company’s employees • need to foster the Company’s business relationships with suppliers, customers and others • impact of the Company’s operations on the community and environment • desirability of the Company maintaining a reputation for high standards of business conduct • need to act fairly as between members of the Company In discharging their duties each Director has regard to the factors set out above and to other factors which they consider relevant to the decision being made. Those factors may include, for example, the interests and views of our shareholders, suppliers and regulators. The Board’s aim is to make sure that decisions are consistent and predictable. Details on how the Board operates and the way directors reach decisions, including some of the matters discussed and debated during the year, the key stakeholder considerations that were central to those discussions and the way in which the Directors had regard to the need to foster the Company’s long-term relationship with shareholders and other stakeholders, are included in the Corporate Governance section of this report on pages 47 to 54. The tables opposite detail the key stakeholders and associated engagements with the Board and the key decisions reached in the year. Section 172 statement

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 27 Key stakeholders Stakeholder Detail regarding stakeholder engagement Shareholders The Directors recognise the value of maintaining regular communications with shareholders. Formal reports are published at the half- year and year-end stages and the Manager publishes periodic newsletters. An opportunity is given to shareholders at each annual general meeting to question the Board and the Manager on matters relating to the Company’s operation and performance. Shareholders are able to observe the annual general meeting virtually if they are not able to attend in person. The Manager holds an annual seminar to which shareholders are invited and the Directors attend. The Board welcomes the opportunity to engage with shareholders at these events. Regulatory News Service (“RNS”) announcements are published in accordance with the Listing Rules and the Disclosure Guidance and Transparency Rules. Investment Manager The Company’s most critical business relationship is with the Manager, Mercia. There is regular contact with Mercia and members of Mercia’s senior leadership team attend the Company’s board meetings. The content discussed at each meeting is over a wide range of topics from Company strategy to issues faced by portfolio companies. The Management Engagement Committee and Board review the performance of the Manager on an ongoing basis. Portfolio companies The Company holds minority investments in its portfolio companies and it has appointed Mercia to manage the portfolio. Whilst day to day interaction with portfolio companies is delegated via the investment management agreement to Mercia, updates are received by the Board at least quarterly. The Directors take an active interest in the challenges faced by portfolio companies. More details can be found on pages 31 to 33. Suppliers The Company has relationships with a number of key suppliers including its auditor, taxation advisers, solicitors, stockbrokers, banks and registrar. The Manager, with the oversight of the Board, monitors the performance of each of the Company’s suppliers on a periodic basis and each has demonstrated continued effectiveness. Community and environment Alongside the Manager, the Company considers its impact on the community and environment. Full details regarding the Company’s approach can be found within the Responsible Investment section of this report on pages 31 to 33. Employees The Company does not have any employees. The Board is comprised of non-executive directors. Key decisions The Directors’ decisions are intended to achieve the Company’s corporate objective. Maintaining the Company’s status as aVCT is a critical element of this. Decision Detail regarding decision made Decision to fundraise The decision was made to fundraise a total of £20 million for the Company. The Board carefully considered its cash requirements over the medium term. The Company continues to actively invest in VCT-qualifying holdings, not only in new investment opportunities but also by providing additional rounds of funding for existing investee companies. This approach requires the Company to maintain a strong reserve of liquid assets, so that sufficient cash resources are available to meet expected future requirements. Decision to increase offer size The Board subsequently approved an increase in the fundraising to £30 million in response to the announced changes to government policy affecting VCT rules, and reflecting strong demand. Payment of dividends The Company targets a dividend of at least 4.5% of the opening NAV per share in each year, subject to protecting the NAV from erosion over the medium term. The Board continues to assess and balance the ability to pay dividends with maintaining a stable NAV when proposing the level of dividends. Future prospects The challenges posed by the slower domestic and global economy persist for UK businesses. Nevertheless, the Directors find encouragement in the overall resilience demonstrated by our portfolio.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 28 Risk management The Audit & Risk Committee carries out a regular and robust assessment of the risk environment in which the Company operates and seeks to identify new risks as they emerge. During the year, the Audit & Risk Committee reviewed the Company’s emerging risk framework and determined that “AI” and advanced technology risk has increased in significance and potential impact and should therefore now be classified as a principal risk. The principal and emerging risks and uncertainties identified by the Audit & Risk Committee and accepted by the Board as potentially affecting the Company’s business model and future performance, and the corresponding steps taken with a view to their mitigation, are as follows: Risk Mitigation Change in risk level Artificial intelligence (“AI”) and advanced technology risk: rapid developments in artificial intelligence and related technologies may present risks (and opportunities) to both the Company and the companies in which it invests. Adoption or use of AI technologies may expose businesses to execution, regulatory, ethical and reputational risks. Conversely, portfolio companies that do not successfully develop or adopt relevant AI-enabled capabilities may face competitive disadvantages. The pace of AI development and the evolving regulatory environment create uncertainty which may adversely affect the operations, valuations or growth prospects of certain investee companies. Any of these factors could adversely affect the performance of the Company and investor returns. The Manager considers technology strategy, data governance, cyber security and regulatory compliance as part of its due diligence and ongoing monitoring of portfolio companies, proportionate to the size, stage and nature of each business. The Board oversees the Manager’s operational control environment, including arrangements with third-party service providers, to ensure appropriate systems, controls and policies are in place in relation to information security, data protection and regulatory compliance. The Board will continue to monitor developments in AI-related regulation and market practice to assess whether additional disclosures or controls are appropriate as the landscape evolves. New Availability of qualifying investments: there can be no guarantee that suitable investment opportunities will be identified in order to meet the Company’s objectives, which could have an adverse effect on investor returns. Additionally, the Company’s ability to obtain maximum value from its investments may be limited by the requirements of the relevant VCT Rules in order to maintain the VCT status of the Company. The Manager has a dedicated investment team that identifies and transacts in qualifying investments. The Directors regularly meet with the Manager to maintain awareness of the pipeline, and factor this into the Company’s fund raising plans. ↔ Economic and geopolitical risk: events such as economic recession or general fluctuation in stock markets, exchange rates and interest rates, notwithstanding recent lower inflation and falling interest rates, may affect the valuation of investee companies and their ability to access adequate financial resources, as well as affecting the Company’s own share price and discount to net asset value. In addition, heightened geopolitical tensions, including developments involving Iran and wider hostilities in the Middle East, alongside US trade policy and the ongoing conflict in Ukraine, may have further economic consequences as a result of increased market volatility and the restricted access to certain commodities and energy supplies. Such conditions may adversely affect the performance of companies in which the Company has invested (or may invest), which in turn may adversely affect the performance of the Company, and may have an impact on the number or quality of investment opportunities available to the Company and the ability of the Manager to realise the Company’s investments. Any of these factors could have an adverse effect on investor returns. The Company invests in a diversified portfolio of investments spanning various industry sectors and which are at different stages of growth. The Company maintains sufficient cash reserves to be able to provide additional funding to investee companies where it is appropriate and in the interests of the Company to do so. The Manager’s team is structured such that appropriate monitoring and oversight is undertaken by an experienced investment executive. As part of this oversight, the investment executive will guide and support the board of each unquoted investee company. At all times, and particularly during periods of heightened economic uncertainty, the investment team of the Manager share best practice from across the portfolio with the investee management teams in order to help with addressing economic challenges. ↑

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 29 Risk Mitigation Change in risk level Financial risk: most of the Company’s investments involve a medium to long-term commitment and many are illiquid. The Directors consider that it is inappropriate to finance the Company’s activities through borrowing except on an occasional short-term basis. Accordingly they seek to maintain a proportion of the Company’s assets in cash or cash equivalents in order to be in a position to pursue new unquoted investment opportunities and to make follow-on investments in existing portfolio companies. The Company has very little direct exposure to foreign currency risk and does not enter into derivative transactions. ↔ Investment and liquidity risk: the Company invests in early stage companies which may be pre-revenue at the point of investment. Portfolio companies may also require significant funds, through multiple funding rounds to develop their technology or the products being developed may be subject to regulatory approvals before they can be launched into the market. This involves a higher degree of risk and company failure compared to investment in larger companies with established business models. Early stage companies generally have limited product lines, markets and financial resources and may be more dependent on key individuals. The securities of companies in which the Company invests are typically unlisted, making them particularly illiquid and may represent minority stakes, which may cause difficulties in valuing and disposing of the securities. The Company may invest in businesses whose shares are quoted on AIM however this may not mean that they can be readily traded and the spread between the buying and selling prices of such shares may be wide. The Directors aim to limit the investment and liquidity risk through regular monitoring of the investment portfolio and oversight of the Manager, who is responsible for advising the Board in accordance with the Company’s investment objective. The investment and liquidity risks are mitigated through the careful selection, close monitoring and timely realisation of investments, by carrying out rigorous due diligence procedures and maintaining a wide spread of holdings in terms of financing stage and industry sector within the rules of the VCT scheme. The Board reviews the investment portfolio and liquidity with the Manager on a regular basis. ↔ Legislative and regulatory risk: in order to maintain its approval as a VCT, the Company is required to comply with current VCT legislation in the UK. Changes to UK legislation in the future could have an adverse effect on the Company’s ability to achieve satisfactory investment returns whilst retaining its VCT approval. Changes to investor tax reliefs, making investments in VCTs relatively less attractive, may result in investors favouring other investment classes, resulting in a lack of demand for the Company’s shares and impact the Company’s ability to fund raise. The Board and the Manager monitor political developments and where appropriate seek to make representations either directly or through relevant trade bodies. The Directors consider these risks to have increased due to a reduction in income tax relief available to investors in the future. ↑ Operational risk: the Company does not have any employees and the Board relies on a number of third-party providers, including the Manager, registrar and custodian, sponsor, receiving agent, lawyers and tax advisers, to provide it with the necessary services to operate. Such operations delegated to the Company’s key service providers may not be performed in a timely or accurate manner, resulting in reputational, regulatory, or financial damage. The risk of cyber-attack or failure of the systems and controls at any of the Company’s third- party providers may lead to an inability to service shareholder needs adequately, to provide accurate reporting and accounting and to ensure adherence to all VCT legislation rules. The Board has appointed an Audit & Risk Committee, who monitor the effectiveness of the system of internal controls, both financial and non- financial, operated by the Company and the Manager. These controls are designed to ensure that the Company’s assets are safeguarded and that proper accounting records are maintained. Third-party suppliers are required to have in place their own risk and controls framework, business continuity plans and the necessary expertise and resources in place to ensure that a high quality service can be maintained even under stressed scenarios. ↔

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 30 Risk Mitigation Change in risk level Performance of the Manager: the successful implementation of the Company’s investment policy is dependent on the expertise of the Manager and its ability to attract and retain suitable staff. The Company’s ability to achieve its investment objectives is largely dependent on the performance of the Manager in the acquisition and disposal of assets and the management of such assets. The Board has broad discretion to monitor the performance of the Manager and the power to appoint a replacement, but the Manager’s performance or that of any replacement cannot be guaranteed. The Board reviews the performance of the Manager formally at Management Engagement Committee meetings and during the year at board meetings. There is ongoing dialogue outside of formal meetings. Performance is closely monitored against other VCT funds and review of other market intelligence. ↔ Stock market risk: a proportion of the Company’s investments are quoted on the London Stock Exchange and AIM and will be subject to market fluctuations upwards and downwards. External factors such as terrorist activity, political activity or global health crises, can negatively impact stock markets worldwide. In times of adverse sentiment there may be very little, if any, market demand for shares in smaller companies quoted on the London Stock Exchange and AIM. The Company’s small number of holdings of quoted investments are actively managed by the Manager, and the Board keeps the portfolio and the actions taken under ongoing review. ↑ VCT qualifying status risk: while it is the intention of the Directors that the Company will be managed so as to continue to qualify as a VCT, there can be no guarantee that this status will be maintained. A failure to continue meeting the qualifying requirements could result in the loss of VCT tax relief, the Company losing its exemption from corporation tax on capital gains, to shareholders being liable to pay income tax on dividends received from the Company and, in certain circumstances, to shareholders being required to repay the initial income tax relief on their investment. The Manager keeps the Company’s VCT qualifying status under continual review and its reports are reviewed by the Board on a quarterly basis. The Board has also retained Philip Hare & Associates LLP to undertake an independent VCT status monitoring role. ↔ The Audit & Risk Committee continually assesses and monitors emerging risks that could impact the Company’s operations and strategic objectives. As part of the risk assessment process, the Audit & Risk Committee evaluates a wide range of potential threats and uncertainties that may arise from evolving market dynamics, regulatory changes, technological advancements, geopolitical developments, and other external factors. By remaining aware of emerging risks, the Audit & Risk Committee by recommendations to the Board ensures that the Company is better equipped to anticipate challenges and adapt swiftly to changing circumstances. The Strategic report was approved by the Board of Directors and is signed on its behalf by Mercia Company Secretarial Services Limited Company Secretary 11 June 2026 Risk management continued

Environmental, social and governance The Company is committed to conducting its affairs responsibly and considers environmental, social and governance (ESG) issues as part of its operations. In addition to its commitment to financial performance, the Board is mindful of the impact of the Company and its investments on the environment alongside its social and corporate governance responsibilities. We recognise that the ESG regulatory and reporting landscape is subject to rapid change, and therefore the Company works closely with the Manager to ensure compliance and develop initiatives. The Company is required, under the Companies Act 2006, to provide details of environmental performance, social, human rights, employee and community issues, including information about any policies it has in relation to these matters and the effectiveness of these policies. As the Company does not have any employees, nor its own premises, the Company does not maintain specific policies in relation to these matters, however the Manager maintains its own policies as appropriate.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 32 Environmental The Company is committed to investing in companies that are aware of their impact on the environment. As part of the Manager’s investment process, environmental risks associated with potential portfolio companies are evaluated. Carbon emission reporting and SECR The Streamlined Energy and Carbon Reporting (SECR) is a UK regulation that requires some large companies to report on their energy use, greenhouse gas emissions, and energy efficiency measures in their annual reports. The Company does not own or lease its own premises and does not employ any staff directly and as the Company consumes under 40MWh of energy per year, it is deemed a ‘low energy user’ and is therefore out of scope for SECR reporting. The Company’s registered office is at the Manager’s head office, which is in the process of finalising its fifth annual review of corporate carbon emissions, in collaboration with Positive Planet. It offset its emissions for the year to March 2025. More information can be found in its annual report. Task Force on Climate-related Financial Disclosures The Company is not in scope for TCFD and the Manager, due to its total assets under management being under £5 billion, is also out of scope. The Company will seek to voluntarily adopt any recommendations made by the Task Force on Climate-related Financial Disclosures (TCFD) which fall within its investment mandate as soon as reasonably practical.Portfolio carbon emissions reporting Your Board is acutely aware of the importance of measuring and reporting the impact of the Company’s complete carbon impact, including the impact of its investments in portfolio companies. Due to the early stage of its investee companies, many do not have the systems or resources in place to accurately record emissions. The Manager is focused on engaging with management teams directly, raising engagement and awareness. Instead of providing emissions data based on a large number of assumptions, the Manager will continue to monitor developments in carbon reporting frameworks and engage with third parties to assess the possibility of reporting on portfolio company level activity once meaningful, auditable data can be provided for the majority of the portfolio. Social The Company’s operations continue to provide social benefits to a wider group of stakeholders. Diversity Your Directors understand the importance of promoting diversity of the Company’s board. The ongoing board succession plan seeks to create a diverse group of experienced individuals. The Board had 14% representation from female directors as at 31 March 2026. The Manager has also committed to encouraging diversity, with several initiatives in place such as: • Being a signatory of the Investing in Women Code, a commitment to support the advancement of female entrepreneurship in the United Kingdom by improving female entrepreneurs’ access to tools, resources and finance from the financial services sector. • Adhering to an Equal Opportunities policy that values and respects all employees, irrespective of role, gender, race, age, sexual orientation or religious belief. National focus The Manager has a network of 11 locations nationwide, enabling local access to its investment team by management teams. This enables the Company to invest in companies spread across the country, not just in London. In total, 68% of the Company’s investment, measured by value, is outside of London. Responsible investment continued

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 33 Governance As providers of Venture Capital with a dedicated investment team of 14 professionals who attend portfolio company board meetings, governance is an area in which your Board and the Manager strongly believe the Company can make a meaningful contribution. Investment process As part of our standard investment process we look for companies with independent and diverse boards, robust internal controls, and a commitment to ethical behaviour and transparency. Management due diligence is performed as part of the investment process, feeding into the decision process on whether to invest. In addition, each investment recommendation from the Manager includes a dedicated section discussing ESG specific risks and value creation opportunities, encouraging the Manager’s investment team and management teams to engage. Portfolio talent and operating partners The Manager supports portfolio companies through a structured approach to leadership, oversight and organisational development, led by a Head of Value Creation. This includes access to experienced operating partners and senior individuals who assist portfolio companies with strategic and operational matters, leadership development, and the maintenance of effective governance frameworks. This approach aligns with the Board’s view that strong corporate governance is essential for long-term success. Value creation By attending board meetings and engaging with management teams, the Manager looks to encourage best practice, creating opportunities for portfolio companies to network, instilling key performance indicators and supporting coaching of portfolio company leadership teams.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 38 The Directors present their report and the audited financial statements for the year ended 31 March 2026. Activities and status The principal activity of the Company during the year was the making of long-term equity and loan investments, mainly in unquoted companies. The Directors have managed the affairs of the Company with the intention of maintaining its status as an approved venture capital trust for the purposes of Section 274 of the Income Tax Act 2007. The Directors consider that the Company was not at any time up to the date of this report a close company within the meaning of Chapter 2 of Part 10 of the Corporation Tax Act 2010. The Company’s registered number is 04280530. A consideration of the environmental impact of the Company’s activities is set out on pages 31 and 32. Corporate governance The statement on Corporate Governance set out on pages 47 to 54 is included in the Directors’ Report by reference. Results and dividend The loss after tax for the year of £952,000 (2025: profit after tax £6,956,000) has been transferred to reserves. The final dividend of 2.5 pence per share in respect of the year ended 31 March 2025 and interim dividend of 2.0 pence per share in respect of the year ended 31 March 2026 were paid during the year at a cost of £6,902,000 and have been charged to reserves. The Directors have proposed a final dividend of 2.5 pence per share for the year ended 31 March 2026. Subject to approval of the final dividend at the Annual General Meeting, the final dividend will be paid on 4 September 2026 to shareholders on the register on 7 August 2026.Provision of information to the auditor Each of the Directors who held office at the date of approval of this Directors’ Report confirms that, so far as they are aware, there is no relevant audit information of which the Company’s auditor is unaware and that they have taken all the steps that they could reasonably be expected to have taken as a director in order to make themselves aware of any relevant audit information and to establish that the Company’s auditor is aware of that information.Statement on long-term viability In accordance with the requirements of the AIC Code of Corporate Governance, the Directors have assessed the prospects of the Company over the three year period to March 2029. The Directors consider that for the purpose of this exercise it is not practical or meaningful to look forward over a period of more than three years and that the period is appropriate for a business of the Company’s nature and size. In making their assessment the Directors have carried out a robust review of the risk environment in which the Company operates, including those risks which might threaten its business model or future performance and the steps taken with a view to their mitigation (see pages 28 to 30 for further details on risk management). The Directors have considered the ability of the Company to comply on an ongoing basis with the conditions for maintaining VCT approved status. The Directors have also considered the nature of the Company’s business, including its substantial reserve of cash and near-cash investments, the potential of its venture capital portfolio to generate future income and capital proceeds and the ability of the Directors to control the level of future cash outflows arising from share buy-backs, dividends and investments. When assessing the potential future cashflows of the Company, the Directors have considered various scenarios including a ‘downside case’ where potential cash inflows are severely impacted by economic disruption. As detailed on page 51, the Management Engagement Committee has also considered the Company’s relationship with the Manager, Mercia, by reference to the performance of the venture capital portfolio and the expertise demonstrated by Mercia in venture capital investment. Directors’ report

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 39 Taking into account the Company’s current position and principal risks, the Directors have concluded that there is a reasonable expectation that the Company will be able to continue in operation over the three year period and meet its liabilities as they fall due over that period. Future developments of the business are discussed in the Outlook section of the Chairman’s statement on page 6. Going concern The financial statements have been prepared on a going concern basis. The Directors performed an assessment of the Company’s ability to meet its liabilities as they fall due. In performing this assessment, the Directors took into consideration the uncertain economic outlook including: • the investments and liquid resources held by the Company; • the fact that the Company has no debt or capital commitments; • the ability of the Company to meet all of its liabilities and ongoing expenses from its assets, including its year-end cash balance; • revenue and operating cost forecasts for the forthcoming year; • the ability of third-party service providers to continue to provide services; and • potential downside scenarios including a fall in the valuation of the investment portfolio or levels of investment income. Based on this assessment, the Directors are confident that the Company will have sufficient funds to continue to meet its liabilities as they fall due for at least 12 months from the date of approval of the financial statements, and therefore determine the going concern basis to be appropriate. An explanation of the significant post-balance sheet events are given in the investment realisations section of the Strategic Report and in Note 21 of the financial statements. Directors None of the Directors has a contract of service with the Company and, except as mentioned below under the heading ‘Management’, no contract or arrangement subsisted during or at the end of the year in which any director was materially interested and which was significant in relation to the Company’s business. A list of each director who has served during the year is given on page 44. Director Diversity In accordance with UKLRs 6.6.6R(10), 6.6.15 G, 11.4.23R and 11.4.24R, the Company confirms that each of the Directors of the Company was asked to confirm the gender that they identify with and their ethnicity, as of 31 March 2026. The responses have been collated and reflect the following data: Number of Board members Percentage of the Board Number of senior positions on the Board (CEO, CFO, SID and Chair) Number in executive management Percentage of executive management Men 6 86% 1 N/A N/A Women 1 14% – N/A N/A Non-binary – – – N/A N/A All other gender identities – – – N/A N/A Not specified/ prefer not to say – – – N/A N/A

The Board recognises the importance, value and strength of having a diverse membership. Although the key objective with any board appointment is to recruit the best person for the job, the Board has strengthened its diversity in the most recent Board appointment(s) and will continue to do so by ensuring the candidate search process utilises proven methods of appealing to a diverse mix of applicants. The Board is exclusively non-executive and as such only the position of Chair is relevant to the Board. Further the Company has not elected to appoint a Senior Independent Director. Directors’ and officers’ liability insurance The Company has, as permitted by the Companies Act 2006, maintained insurance cover on behalf of the Directors and secretary indemnifying them against certain liabilities which may be incurred by any of them in relation to the Company. Management Mercia took over management of the Company’s investment affairs on 23 December 2019 after the novation of the pre-existing management agreement between the Company and NVM Private Equity LLP (NVM), who had acted as manager since the Company’s inception. The principal terms of the Company’s management agreement with Mercia are set out in Note 3 to the financial statements. The Management Engagement Committee carries out a regular review of the terms of Mercia’s appointment with a view to ensuring that Mercia’s remuneration is set at an appropriate level, having regard to the nature of the work carried out and general market practice. As required by the Listing Rules, the Directors confirm that in their opinion the continuing appointment of Mercia as Manager on the terms agreed is in the interests of the Company’s shareholders as a whole. In reaching this conclusion the Directors have taken into account the performance of the investment portfolio and the efficient and effective service provided by Mercia to the Company. Directors’ report continued

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 41 Remuneration receivable by the Manager The remuneration receivable by the Manager by virtue of the management agreement with the Company comprises the following: Remuneration payable by the Company Basic management fee: the Manager is entitled to receive a basic annual management fee equivalent to 2.06% of net assets, calculated half-yearly as at 31 March and 30 September. In consenting to the novation of the management agreement to Mercia in December 2019, it was agreed that the fee due on the value of liquid assets above the threshold of £20 million would continue to attract a reduced rate of 1% per annum on a permanent basis. In the year ended 31 March 2026 the basic annual management fee was £2,537,000 (2025: £2,327,000). Performance-related management fee: performance-related management fees are payable on annual performance above the higher of the annual hurdle of 5% of opening NAV per share and the difference between the cumulative total return brought forward to its high water mark (together, the ‘Excess Return’). The performance-related management fee is calculated at 14% of the Excess Return and the payment of the performance-related management fee in any one year is capped to 2.25% of the net asset value at the start of the year with the balance being deferred. There was no performance-related management fee due for the year ended 31 March 2026 (2025: £65,000). Accounting and secretarial fee: the Manager is responsible for providing accounting, administrative and secretarial services to the Company for an annual fee of £74,000 (2025: £72,000), linked to the movement in the CPI. The total remuneration payable in aggregate to the Manager by the Company in respect of the year, comprising the basic management fee, the performance-related management fee and the accounting and secretarial fee, was £2,611,000 (2025: £2,464,000). Under current tax legislation the fees paid by the Company to the Manager are not subject to VAT. The total annual running costs of the Company, including the basic management fee and the accounting and secretarial fee but excluding the performance-related management fee, are capped at 2.9% of average net assets and any excess will be refunded to the Company by way of a reduction in the Manager’s basic management fee. The annual running costs of the Company for the year ended 31 March 2026 were equivalent to 2.28% of average net assets (2025: 2.20%). Remuneration payable by investee companies Under the management agreement, the Manager is entitled to receive fees from investee companies in respect of the arrangement of investments and the provision of non-executive directors and other advisory services. The Manager is responsible for paying the due diligence and other costs incurred in connection with proposed investments which for whatever reason do not proceed to completion. In the year ended 31 March 2026 the arrangement fees receivable by the Manager from investee companies which were attributable to investments made by the Company amounted to £437,000 (2025: £404,000), and directors’ and monitoring fees amounted to £343,000 (2025: £345,000). Executive co-investment scheme Since 2006 the Company has, together with the other VCT funds managed by Mercia, participated in a co-investment scheme with the objective of enabling the Manager to recruit, retain and incentivise its key investment personnel. Under the scheme executives are required to invest personally (and on the same terms as the Company and other VCT funds managed by Mercia) in the ordinary share capital of every unquoted investee company in which the Company invests. Since the novation of the management agreement to Mercia, Mercia has managed a new co-investment scheme. The shares held by executives can only be sold at such time as the VCT funds advised by Mercia sell their shares and any prior ranking loan notes or preference shares held by the funds having been repaid.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 43 Directors’ remuneration report This report has been prepared by the Directors in accordance with the requirements of Section 420 of the Companies Act 2006. A resolution to approve the Directors’ Remuneration Report will be proposed at the Annual General Meeting on 30 July 2026. The Company’s independent auditor, Johnston Carmichael LLP, is required to give its opinion on certain information included in this report, as indicated below. The auditor’s report on these and other matters is set out on pages 56 to 62. Directors’ remuneration policy The Board currently comprises seven directors, all of whom are non- executive. The Board does not have a separate Remuneration Committee, as the Company has no employees or executive directors. The Board has established a Nomination Committee, chaired by Mr J G D Ferguson and comprising all of the Directors, which meets annually (or more frequently if required) to consider the selection and appointment of directors and to make recommendations to the Board as to the level of directors’ fees. The Board has not retained external advisers in relation to remuneration matters but has access to information about directors’ fees paid by other companies of a similar size and type. The Board considers that directors’ fees should reflect the time commitment required and the high level of responsibility borne by directors, and should be broadly comparable to those paid by similar companies. It is not considered appropriate that either new or existing directors’ remuneration should be performance-related, and none of the Directors are eligible for bonuses, pension benefits, share options, long-term incentive schemes or other benefits in respect of their services as non-executive directors of the Company. The articles of association place an overall limit (currently £200,000 per annum) on directors’ remuneration. The articles of association provide that directors shall retire and be subject to re-election at the first annual general meeting after their appointment and that any director who was not appointed or re-appointed at one of the preceding two annual general meetings shall retire and be subject to re-election at each annual general meeting. As a matter of good practice, the Board has adopted the 2024 AIC Code recommendation that all directors should seek annual re- election. None of the Directors has a service contract with the Company. On being appointed or re-elected, directors receive a letter from the Company setting out the terms of their appointment and their specific duties and responsibilities. A director’s appointment may be terminated on three months’ notice being given by the Company and in certain other circumstances. A director who ceases to hold office is not entitled to receive any payment other than accrued fees (if any) for past services. An ordinary resolution to approve the Directors’ remuneration policy of the Company was approved by shareholders at the Annual General Meeting of the Company on 27 July 2023 and remains in force for a three-year period. Shareholder approval will be sought for the Directors’ remuneration policy at the Company’s AGM on 30 July 2026.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 47 The Board of Northern 3 VCT PLC has considered the Principles and Provisions of the Association of Investment Companies Corporate Governance Code (AIC Code). The AIC Code addresses the Principles and Provisions set out in the UK Corporate Governance Code (the UK Code), adapts the UK Code to make the Principles and Provisions relevant for investment companies and sets out additional Provisions on issues that are of specific relevance to investment companies. The Board considers that reporting against the Principles and Provisions of the AIC Code which has been endorsed by the Financial Reporting Council, provides more relevant information to shareholders than reporting against the UK Code. The AIC Code is available on the AIC website (www.theaic.co.uk). The Company is committed to maintaining high standards in corporate governance and during the year ended 31 March 2026 has complied with the Principles and Provisions of the AIC Code, with the exception of provisions 13, 14, 24 and 25 which have not been applied for the reasons detailed below. Board of directors The Company has a board of seven non-executive directors, all of whom are considered to be independent of the Company’s Manager, Mercia Fund Management Limited (Mercia). The Board meets regularly in person or by conference call five times each year, and on other occasions as required. The Board is responsible to shareholders for the effective stewardship of the Company’s affairs and has a formal schedule of matters specifically reserved for its decision which include: • consideration of long-term strategic issues; • valuation of the unquoted investment portfolio; and • ensuring the Company’s compliance with good practice in corporate governance matters. A brief biographical summary of each director is given on pages 34 to 37. The Chairman, Mr J G D Ferguson, leads the Board in the determination of its strategy and in the achievement of its objectives. The Chairman is responsible for organising the business of the Board, ensuring its effectiveness and setting its agenda, and has no involvement in the day to day business of the Company. He facilitates the effective contribution of the Directors and ensures that they receive accurate, timely and clear information and that they communicate effectively with shareholders. The Board has established a formal process, led by the Chairman, for the annual evaluation of the performance of the Board, its principal committees and individual directors. The Directors are made aware on appointment that their performance will be subject to regular evaluation. The performance of the Chairman is evaluated by a meeting of the other board members under the leadership of Mr C J Fleetwood. The Chairman has not felt that an external Board review is necessary. The Company Secretary, Mercia Company Secretarial Services Limited, is responsible for advising the Board through the Chairman on all governance matters. All of the Directors have access to the advice and services of the Company Secretary, which has administrative responsibility for the meetings of the Board and its committees. Directors may also take independent professional advice at the Company’s expense where necessary in the performance of their duties. The Company’s articles of association and the schedule of matters reserved to the Board for decision provide that the appointment and removal of the Company Secretary is a matter for the Board. As detailed in the table on page 52 the Board met five times during the year as part of its regular programme of Board meetings and on another five occasions by conference call. The matters discussed and approved during the year include the key decisions set out on page 27, the approval of share buybacks, the allotment of shares pursuant to the Dividend Investment Scheme, review of the terms of reference of each of the Committees of the Board and horizon scanning for changes in legislation and regulatory guidance that applies to the Company. Corporate governance

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 48 Provision 14 of the AIC Code recommends the appointment of a senior independent non-executive director to provide a sounding board for the Chairman and serve as an intermediary for the other directors and shareholders. The Board has opted not to appoint a senior independent director and does not comply with this AIC Code provision. The Board has concluded that given the size and composition of the Board (consisting entirely of experienced non-executive directors), the appointment of a senior independent non-executive director is not appropriate: 1. the Chairman has the ability to use each of the Directors as a sounding board as required from time to time; 2. the Board members have confirmed that given the access they have to the Chairman, they do not require another director to act as an intermediary on their behalf. The Directors do not consider that appointing a senior non-executive would provide any benefit to shareholders, who already have the ability to contact the Company, Board and its Manager through a variety of channels. Providing another director as a point of access would not enhance this process. 3. Board members formally assess the Chairman’s performance annually without input from the Chairman and there is no need to appoint a senior non-executive in respect of this process. The articles of association provide that directors shall retire and be subject to election at the first annual general meeting after their appointment and that any director who was not appointed or re-appointed at one of the preceding two annual general meetings shall retire and be subject to re-election at each annual general meeting. However the Board has as a matter of good practice adopted the AIC Code recommendation that all directors should seek annual re-election. Independence of directors The Board regularly reviews the independence of its members and is satisfied that the Company’s directors are independent in character and judgement and there are no relationships or circumstances which could affect their objectivity. Provision 13 of the AIC Code recommends that where a director has served for more than nine years, the Board should state its reasons for believing that the individual remains independent. The Board is of the view that a term of service in excess of nine years is not in itself prejudicial to a director’s ability to carry out their duties effectively and from an independent perspective; the nature of the Company’s business is such that individual directors’ experience and continuity of Board membership can significantly enhance the effectiveness of the Board as a whole. Provision 24 of the AIC Code recommends determining and disclosing a policy on the tenure of the Chair. The Company does not have a set limit on the tenure of the members of the Board and the Chairman and therefore does not comply with this provision. However the Board has as a matter of good practice adopted the AIC Code recommendation that all directors should seek annual re-election, and acknowledges that regular refreshment of its membership is desirable. Board committees The Board has appointed three standing committees to make recommendations to the Board in specific areas. The Board does not have a separate Remuneration Committee, as the Company has no employees or executive directors. Detailed information relating to the remuneration of directors is given in the Directors’ Remuneration Report on pages 44 and 45. Corporate governance continued

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 49 Audit & Risk Committee During the year the Audit & Risk Committee comprised: Mr C J Fleetwood (Chair) Mrs A B Brown Mr J G D Ferguson Mr T R Levett Mr D S Ovens (appointed 24 April 2025) Mr J M O Waddell Mr J Younger (appointed 13 February 2026) The Audit & Risk Committee’s terms of reference include the following roles and responsibilities: • monitoring the integrity of the financial statements of the Company and any formal announcements relating to the Company’s financial performance, and reviewing significant financial reporting judgements contained in them; • providing advice (where requested by the Board) on whether the annual report and accounts, taken as a whole, is fair, balanced and understandable, and provides the information necessary for shareholders to assess the Company’s position and performance, business model and strategy; • following Audit Committees and the External Audit: Minimum Standard, issued by the Financial Reporting Council in May 2023; • reviewing the Company’s risk management and internal control framework by monitoring and making recommendations to the Board in relation to the Company’s internal control (including internal financial control) and risk management systems; • reporting to the Board on how it has discharged its responsibilities; • monitoring and making recommendations to the Board in relation to the valuation of the Company’s unquoted investments; • periodically considering the need for an internal audit function; • making recommendations to the Board in relation to the appointment, re-appointment and removal of the external auditor and approving the remuneration and terms of engagement of the external auditor; • reviewing and monitoring the external auditor’s independence and objectivity and the effectiveness of the audit process, taking into consideration relevant UK professional and regulatory requirements; • monitoring the extent to which the external auditor is engaged to supply non-audit services; and • ensuring that the Manager has arrangements in place for the investigation and follow-up of any concerns raised confidentially by staff in relation to the propriety of financial reporting or other matters. The Audit & Risk Committee reviews its terms of reference and its effectiveness annually and recommends to the Board any changes required as a result of the review. The terms of reference are available on request from the Company Secretary and on the Company’s website. The Audit & Risk Committee ordinarily meets three times per year and has direct access to Johnston Carmichael LLP, the Company’s external auditor. The Board considers that the members of the Audit & Risk Committee are independent and have collectively the skills and experience required to discharge their duties effectively, and that the Chair of the Audit & Risk Committee meets the requirements of the AIC Code as to recent and relevant financial experience. During the year ended 31 March 2026 the Company did not have an independent internal audit function as it is not deemed necessary given the size of the Company and the nature of the Company’s business. However, the Audit & Risk Committee considers annually whether there is a need for such a function and makes a recommendation to the Board. During the year ended 31 March 2026 the Audit & Risk Committee discharged its responsibilities by: • the engagement and onboarding of Johnston Carmichael LLP as auditor to the Company, following a formal audit tender process carried out in the year to 31 March 2025 and with shareholder approval of the appointment obtained at the 2025 AGM; • reviewing and approving the external auditor’s remuneration and independence; • reviewing the external auditor’s plan for the audit of the Company’s financial statements, including identification of key risks and confirmation of auditor independence;

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 50 • reviewing the Manager’s statement of internal controls operated in relation to the Company’s business and assessing the effectiveness of those controls in minimising the impact of key risks. The Committee has carried out a granular review of the control framework in readiness for the implementation of amended Provision 34 of the AIC Code for the financial year 1 April 2026 to 31 March 2027; • reviewing periodic reports on the effectiveness of the Manager’s compliance procedures; • reviewing the appropriateness of the Company’s accounting policies; • reviewing the Company’s draft annual financial statements and half- yearly results statement prior to Board approval, including the proposed fair value of investments; • reviewing the external auditor’s detailed reports to the Audit & Risk Committee on the annual financial statements; • reviewing the taxation advisers’ VCT status monitoring and compliance reports; and • considering the effectiveness of the external audit process. The key area of risk that has been identified and considered by the Audit & Risk Committee in relation to the business activities and financial statements of the Company is the valuation and existence of unquoted investments, particularly in light of economic uncertainty caused by inflationary pressures, higher interest rates, global economic slowdown and geopolitical tensions. Another important area of risk that is considered by the Audit & Risk Committee is compliance with HM Revenue & Customs conditions for maintenance of approved venture capital trust status. These issues were discussed with the Manager and the auditor at the pre- year end audit planning meeting and at the conclusion of the audit of the financial statements. Valuation of unquoted investments: the Manager confirmed to the Audit & Risk Committee that the investment valuations had been carried out consistently with prior periods and in accordance with published industry guidelines, taking account of the latest available information about investee companies and current market data. The Audit & Risk Committee reviewed the estimates and judgements used in the investment valuations and was satisfied that the final valuations are appropriate. Venture capital trust status: the Manager confirmed to the Audit & Risk Committee that the conditions for maintaining the Company’s status as an approved venture capital trust had been complied with throughout the year. The position was also confirmed and reported on by Philip Hare & Associates LLP in its capacity as adviser to the Company on taxation matters and the relevant report was reviewed by the Audit & Risk Committee. The Manager and auditor confirmed to the Audit & Risk Committee that they were not aware of any material misstatements. Having reviewed the reports received from the Manager and auditor, the Audit & Risk Committee is satisfied that the key areas of risk and judgement have been appropriately addressed in the financial statements and that the significant assumptions used in determining the value of assets and liabilities have been properly appraised and are sufficiently robust. The Audit & Risk Committee considers that Johnston Carmichael LLP has carried out its duties as auditor in a diligent and professional manner. Following a detailed review of the draft annual report, the Audit & Risk Committee concluded that, taken as a whole, it was considered to be fair, balanced and understandable. The Audit & Risk Committee recommended to the Board that the Directors’ responsibilities statement in respect of the annual report and the financial statements, should be signed accordingly. The Audit & Risk Committee regularly reviews and monitors the auditor’s effectiveness and independence by considering the following criteria: qualification, expertise, resources, effectiveness, independence and leadership. Taking into account the views of the Manager regarding the audit process, formal documentation issued to the Audit & Risk Committee and the board by the auditor regarding the external audit for the year ended 31 March 2026 and assessments made by the Directors of the Company, the Audit & Risk Committee was satisfied that Johnston Carmichael LLP is effective, has the appropriate qualifications and expertise to carry out the audit of the Company and has demonstrated sufficient resource applied under competent and effective leadership. Johnston Carmichael LLP has confirmed that it is independent of the Company and has complied with the applicable auditing standards. There were no non-audit services contracted during the period. In accordance with professional guidelines the engagement leader is rotated after at most five years; this is the first year that the current partner has served. Corporate governance continued

The Nomination Committee monitors the balance of skills, knowledge, diversity and experience offered by Board members, and satisfies itself that they are able to devote sufficient time to carry out their role efficiently and effectively. When recommending new appointments to the Board, the Nomination Committee draws on its members’ extensive business experience and range of contacts to identify suitable candidates, and would consider the use of formal advertisements and external consultants where appropriate. The Nomination Committee recognises the benefits of diversity in the constitution of the Board and it is the Nomination Committee’s intention that the diversity of representation on the Board will continue to increase over time. New directors are provided with briefing material relating to the Company, its Manager and the venture capital industry as well as to their own legal responsibilities as directors. The Nomination Committee has written terms of reference which are reviewed annually and are available on request from the Company Secretary and on the Company’s website. The Nomination Committee met during the year to commence the search processes that resulted in the appointment of David Ovens and Jamie Younger. Both searches were conducted by the Nomination Committee drawing on candidates from its extensive network of non-executive directors. AIC Code provision 25 states that open advertising and/or an external search consultancy should generally be used for the appointment of non-executive directors. The Committee was satisfied that the search process carried out was sufficiently broad and delivered an exceptional pool of candidates, such that it was acceptable not to comply with the Code on this occasion. The offers made to Mr D S Ovens and Mr J Younger were formally approved by the Board of Directors. As part of the Board’s ongoing succession planning, Mr C J Fleetwood and Mr T R Levett will retire from the Board at this year’s AGM. Management Engagement Committee During the year the Management Engagement Committee comprised: Mr J G D Ferguson (Chairman) Mrs A B Brown Mr C J Fleetwood Mr T R Levett Mr D S Ovens (appointed 24 April 2025) Mr J M O Waddell Mr J Younger (appointed 13 February 2026) The Management Engagement Committee undertakes a periodic review of the performance of the Manager, Mercia, and of the terms of the management agreement including the level of fees payable and the length of the notice period. The principal terms of the agreement are set out in Note 3 to the financial statements on page 71. Following the latest review by the Management Engagement Committee, the Board concluded that the continuing appointment of Mercia was in the interests of the Company and its shareholders as a whole. Mercia has demonstrated its commitment to, and expertise in, venture capital investment since its appointment. Mercia has also performed its company secretarial and accounting duties efficiently and effectively.

Corporate responsibility The Board aims to ensure that the Company takes a positive approach to corporate responsibility, in relation both to itself and to the companies it invests in. This entails maintaining a responsible attitude to ethical, environmental, governance and social issues, and the encouragement of good practice in investee companies. The Board seeks to avoid investing in companies which do not operate within relevant ethical, environmental and social legislation or otherwise fail to comply with appropriate industry standards. Investor relations In fulfilment of the Chairman’s obligations under the AIC Code, the Chairman gives feedback to the Board on any issues raised with him by shareholders with a view to ensuring that members of the Board develop an understanding of the views of shareholders about their company. The Board recognises the value of maintaining regular communications with shareholders. Formal reports are sent to shareholders at the year-end in accordance with their communication preferences, and an opportunity is given to shareholders at each annual general meeting to question the Board and the Manager on matters relating to the Company’s operation and performance. The Manager holds an annual VCT investor seminar to which shareholders are invited. Proxy voting figures for each resolution are announced at general meetings and are made available publicly following the relevant meeting. Further information can also be obtained via the Company’s website. Internal control The Directors have overall responsibility for ensuring that there are in place robust systems of internal control, both financial and non-financial, and for reviewing their effectiveness. The purpose of the internal financial controls is to ensure that proper accounting records are maintained, the Company’s assets are safeguarded and the financial information used within the business and for publication is accurate and reliable; such a system can provide only reasonable and not absolute assurance against material misstatement or loss. The Board regularly reviews financial performance and results with the Manager. Responsibility for accounting and secretarial services has been contractually delegated to Mercia under the management agreement. Mercia has established its own system of internal controls in relation to these matters, details of which have been reviewed by the Audit & Risk Committee. Non-financial internal controls include the systems of operational and compliance controls maintained by the Manager in relation to the Company’s business as well as the management of key risks as referred to in the section headed ‘Risk management’ below. The Directors confirm that by means of the procedures set out above, and in accordance with ‘Guidance on Risk Management, Internal Control and Related Financial and Business Reporting’, published by the Financial Corporate governance continued

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 53 Reporting Council, they have established a continuing process for identifying, evaluating and managing the significant potential risks faced by the Company and have reviewed the effectiveness of the internal control systems. This process has been in place throughout, and subsequent to, the accounting period under review. In readiness for the application of updated provision 34 of the AIC Code with effect from 1 April 2026, following the recommendation of the Audit & Risk Committee, the Board has agreed the Company’s risk management and controls framework, including the controls that are managed by the Manager. The Board will be able to monitor and review the effectiveness of the framework in the year to 31 March 2027. This will enable the Board to make an appropriate declaration of effectiveness of the material controls as at the balance sheet date and identify any material controls that have not operated effectively and the actions that will be taken to improve them. Risk management Risk management is discussed in the Strategic Report on pages 28 to 30. Share capital, rights attaching to the shares and restrictions on voting and transfer As at 31 March 2026 there were 157,645,007 ordinary shares in issue (as at that date none of the issued shares were held by the Company as treasury shares). Subject to any suspension or abrogation of rights pursuant to relevant law or the Company’s articles of association, the shares confer on their holders (other than the Company in respect of any treasury shares) the following principal rights: (a) the right to receive out of profits available for distribution such dividends as may be agreed to be paid (in the case of a final dividend in an amount not exceeding the amount recommended by the Board as approved by shareholders in general meeting or in the case of an interim dividend in an amount determined by the Board). All dividends unclaimed for a period of 12 years after having become due for payment are forfeited automatically and cease to remain owing by the Company; (b) the right, on a return of assets on a liquidation, reduction of capital or otherwise, to share in the surplus assets of the Company remaining after payment of its liabilities pari passu with the other holders of ordinary shares; and (c) the right to receive notice of and to attend and speak and vote in person or by proxy at any general meeting of the Company. On a show of hands every member present or represented and voting has one vote and on a poll every member present or represented and voting has one vote for every share of which that member is the holder; the appointment of a proxy must be received not less than 48 hours before the time of the holding of the relevant meeting or adjourned meeting or, in the case of a poll taken otherwise than at or on the same day as the relevant meeting or adjourned meeting, be received after the poll has been demanded and not less than 24 hours before the time appointed for the taking of the poll. These rights can be suspended. If a member, or any other person appearing to be interested in shares held by that member, has failed to comply within the time limits specified in the Company’s articles of association with a notice pursuant to Section 793 of the Companies Act 2006 (notice by company requiring information about interests in its shares), the Company can until the default ceases suspend the right to attend and speak and vote at a general meeting and if the shares represent at least 0.25% of their class the Company can also withhold any dividend or other money payable in respect of the shares (without any obligation to pay interest) and refuse to accept certain transfers of the relevant shares. Shareholders, either alone or with other shareholders, have other rights as set out in the Company’s articles of association and in the Companies Act 2006. A member may choose whether their shares are evidenced by share certificates (certificated shares) or held in electronic (uncertificated) form in CREST (the UK electronic settlement system). Any member may transfer all or any of their shares, subject in the case of certificated shares to the rules set out in the Company’s articles of association or in the case of uncertificated shares to the regulations governing the operation of CREST (which allow the Directors to refuse to register a transfer as therein set out); the transferor remains the holder of the shares until the name of the transferee is entered in the register of members. The Directors may refuse to register a transfer of certificated shares in favour of more than four persons jointly or where there is no adequate evidence of ownership or the transfer is not duly stamped (if so required). The Directors may also refuse to register a share transfer if it is in respect of a certificated share which is not fully paid up or on which the Company has a lien provided that, where the share transfer is in respect of any share admitted to the Official List

Whilst there are no squeeze-out and sell-out rules relating to the shares in the Company’s articles of association, shareholders are subject to the compulsory acquisition provisions in Sections 974 to 991 of the Companies Act 2006. Amendment of articles of association The Company’s articles of association may be amended by the members of the Company by special resolution (requiring a majority of at least 75% of the persons voting on the relevant resolution). Appointment and replacement of directors A person may be appointed as a director of the Company by the shareholders in a general meeting by ordinary resolution (requiring a simple majority of the persons voting on the relevant resolution) or by the Directors; no person, other than a director retiring by rotation or otherwise, shall be appointed or reappointed as director at any general meeting unless they are recommended by the Directors or, not less than seven or more than 42 clear days before the date appointed for the meeting, notice is given to the Company of the intention to propose that person for appointment or re-appointment in the form and manner set out in the Company’s articles of association. Each director who is appointed by the Directors (and who has not been elected as a director of the Company by the members at a general meeting held in the interval since his appointment as a director of the Company) is to be subject to election as a director of the Company by the members at the first annual general meeting of the Company following their appointment. At each annual general meeting of the Company, any director who was not appointed or re-appointed at one of the preceding two annual general meetings shall retire and be subject to re-election. As a matter of good practice, the Board has adopted the AIC Code recommendation that all directors should seek annual re-election. The Companies Act 2006 allows shareholders in general meeting by ordinary resolution (requiring a simple majority of the persons voting on the relevant resolution) to remove any director before the expiration of their period of office, but without prejudice to any claim for damages which the director may have for breach of any contract of service between them and the Company. A person also ceases to be a director if they resign in writing, cease to be a director by virtue of any provision of the Companies Act, become prohibited by law from being a director, become bankrupt or is the subject of a relevant insolvency procedure, or becomes of unsound mind, or if the Board so decides following at least six months’ absence without leave or if they become subject to relevant procedures under the mental health laws, as set out in the Company’s articles of association. Powers of the Directors The Company’s articles of association specify that, subject to the provisions of the Companies Act 2006 and articles of association of the Company and any directions given by shareholders by special resolution, the business of the Company is to be managed by the Directors, who may exercise all the powers of the Company, whether relating to the management of the business or not, except where the Companies Act 2006 or the articles of association of the Company otherwise require. In particular the Directors may exercise on behalf of the Company its powers to purchase its own shares to the extent permitted by shareholders. Authority was given at the Company’s 2025 Annual General Meeting to make market purchases of up to 15,111,065 ordinary shares at any time up to the 2026 Annual General Meeting and otherwise on the terms set out in the relevant resolution, and renewed authority is being sought at the Annual General Meeting to be held on 30 July 2026 as set out in a separate circular.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 55 Directors’ responsibilities statement The Directors are responsible for preparing the annual report and financial statements in accordance with applicable law and regulations. Company law requires the Directors to prepare financial statements for each financial year. Under that law they are required to prepare the financial statements in accordance with UK accounting standards, including FRS 102 ‘The Financial Reporting Standard applicable in the UK and Republic of Ireland’. Under company law the Directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs of the Company and of its profit or loss for the year. In preparing these financial statements, the Directors are required to: • select suitable accounting policies and then apply them consistently; • make judgements and estimates that are reasonable and prudent; • state whether applicable UK accounting standards have been followed, subject to any material departures disclosed and explained in the financial statements; • assess the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern; and • use the going concern basis of accounting unless they either intend to liquidate the Company or to cease operations, or have no realistic alternative but to do so. The Directors are responsible for keeping adequate accounting records that are sufficient to show and explain the Company’s transactions and disclose with reasonable accuracy at any time the financial position of the Company and enable them to ensure that its financial statements comply with the Companies Act 2006. They are responsible 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, and have general responsibility for taking such steps as are reasonably open to them to safeguard the assets of the Company and to prevent and detect fraud and other irregularities. Under applicable law and regulations, the Directors are also responsible for preparing a Strategic Report, Directors’ Report, Directors’ Remuneration Report and Corporate Governance Statement that complies with that law and those regulations. The Directors are responsible for the maintenance and integrity of the corporate and financial information included on the Company’s website. Legislation in the UK governing the preparation and dissemination of financial statements may differ from legislation in other jurisdictions. Responsibility statement of the Directors in respect of the annual report and financial statements for the year ended 31 March 2026 We confirm that to the best of our knowledge: • the financial statements, prepared in accordance with the applicable set of accounting standards, give a true and fair view of the assets, liabilities, financial position and profit or loss of the Company; and • the Strategic Report and Directors’ Report include a fair review of the development and performance of the business and the position of the issuer, together with a description of the principal risks and uncertainties that they face. We consider the annual report and accounts, taken as a whole, is fair, balanced and understandable and provides the information necessary for shareholders to assess the Company’s position and performance, business model and strategy.By order of the Board Mercia Company Secretarial Services Limited Company Secretary 11 June 2026

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 56 Independent auditor’s report To the members of Northern 3 VCT PLC Opinion We have audited the financial statements of Northern 3 VCT PLC (“the Company”), for the year ended 31 March 2026, which comprise the Income statement, the Balance sheet, the Statement of changes in equity, the Statement of cash flows and the Notes to the financial statements, including 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 Practice). In our opinion the financial statements: • Give a true and fair view of the state of the Company’s affairs as at 31 March 2026 and of its return for the year then ended; • Have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and • Have been prepared in accordance with the requirements of the Companies Act 2006. Basis for opinion We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditor responsibilities for the audit of the financial statements section of our report. We are independent of the Company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC’s Ethical Standard, as applied to listed public interest entities, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.Our approach to the audit We planned our audit by first obtaining an understanding of the Company and its environment, including its key activities delegated by the Board to relevant approved third-party service providers and the controls over provision of those services. We conducted our audit using information maintained and provided by Mercia Fund Management Limited (the “Manager”), Mercia Company Secretarial Services Limited (the “Company Secretary”, and “Administrator”), Brewin Dolphin Limited (the “Listed Investments Custodian”) and The City Partnership (UK) Limited (the “Registrar”) to whom the Company has delegated the provision of services. We tailored the scope of our audit to reflect our risk assessment, taking into account such factors as the types of investments within the Company, the involvement of the Administrator, the accounting processes and controls, and the industry in which the Company operates. The scope of our audit was influenced by our application of materiality. We set certain quantitative thresholds for materiality. These together with qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of our audit procedures on the individual financial statement line items and disclosures and in the evaluation of the effect of misstatements, both individually and in aggregate on the financial statements as a whole. Key audit matters Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements of the current period and include the most significant assessed risks of material misstatement (whether or not due to fraud) that we identified. These matters included those which had the greatest effect on: the overall audit strategy; the allocation of resources in the audit; and directing the efforts of the engagement team. These matters were addressed in the context of our audit of the financial statements as a whole, and in forming our opinion thereon, we do not provide a separate opinion on these matters. We summarise below the key audit matter in arriving at our audit opinion above, together with how our audit addressed this matter and the results of our audit work in relation to this matter.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 57 Key Audit Matter How our audit addressed the key audit matter and our conclusions Valuation and ownership of unlisted investments (as per page 50 (Audit & Risk Committee Report), page 68 (Accounting Policies) and Note 8). The valuation of the unlisted investment portfolio at 31 March 2026 was £93.4 million. As this is the largest component of the Company’s Balance sheet, and there is a high degree of subjectivity in the valuation of unlisted investments, it has been designated as a key audit matter, being one of the most significant assessed risks of material misstatement due to fraud or error. The unlisted investments are valued in accordance with the revised International Private Equity and Venture Capital (IPEV) valuation guidelines. Significant judgement is required in applying these principles and determining certain inputs to the valuation models. Additionally, there is a risk that the investments recorded as held by the Company may not represent the property of the Company. In order to address the risks associated with the valuation and ownership of the unlisted investment portfolio, we: • Performed a walkthrough of the valuation and ownership process for unlisted investments at the Administrator and Manager, to evaluate the design and implementation of key controls; • Obtained evidence of the Board’s challenge and approval of all valuations; • As part of our risk assessment procedures, we stratified the unlisted investments portfolio and selected a sample of investments for detailed testing based on this risk-based stratification. For the investments in our sample: • We obtained an understanding of the sector for each investee company for the period being audited, and made enquiries of management; • We gained an understanding of the original investment rationale and valuation basis, along with any milestones set; • We obtained an update on the investment, paying particular attention to progress against pre-set milestones and/or indications that a reduction in valuation may be appropriate; • We assessed the appropriateness of the valuation basis used, paying particular attention to any changes from the prior year valuation basis; • We agreed data used in the valuation models to independent sources and assessed how management assess the accuracy and reliability of investee company information; • Where deemed appropriate, we engaged our specialist corporate finance team to review certain judgemental inputs to valuations, such as multiples and discounts; and • We reperformed the enterprise value calculations and waterfalls to ensure mathematical accuracy. • Performed back-testing over investment disposals to assess for potential management bias in the valuation process; • Ensured that accounting estimates and related disclosures were appropriately disclosed in the financial statements; • Agreed the ownership of 100% of the investments through physical verification of the share certificates and loan notes, or via independently obtained confirmations from the underlying investee companies; • For a sample of purchases and disposals agreed the transaction details to sale and purchase agreements and receipts traced and agreed to bank; • For a sample of follow-on investments agreed cashflows to sale and purchase agreements and VCT compliance approvals and transactions traced and agreed to bank; and • Agreed follow-on investments to share certificates and loan note agreements to verify the ownership of the investments, with all payments and receipts traced and agreed to bank. From our completion of these procedures, we identified no material misstatements in relation to valuation and ownership of unlisted investments.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 58 Our application of materiality We define materiality as the magnitude of misstatement in the financial statements that makes it probable that the economic decisions of a reasonably knowledgeable person would be changed or influenced. We use materiality in determining the nature and extent of our work and in evaluating the results of that work. Materiality measure Value Materiality for the financial statements as a whole We have set materiality as 2% of net assets as we believe that net assets is the primary performance measure used by investors and is the key driver of shareholder value. We determined the measurement percentage to be commensurate with the risk and complexity of the audit and the Company’s listed status. We initially set our overall materiality at £2.70m. This was revised during the course of our audit due to a later adjustment recorded in respect of investment valuations. £2.68m Performance materiality Performance materiality represents amounts set by the auditor at less than materiality for the financial statements as a whole, to reduce to an appropriately low level the probability that the aggregate of uncorrected and undetected misstatements exceeds materiality for the financial statements as a whole. In setting this we consider the Company’s overall control environment and any experience of the audit that indicates a lower risk of material misstatements. Based on our judgement of these factors, as well as the fact that this is the first year we are performing the audit, we have set performance materiality at 50% of our overall financial statement materiality. The revision to our overall materiality level noted above did not result in a requirement to revise our performance materiality under the Firm’s methodology. £1.35m Materiality measure Value Specific materiality Recognising that there are transactions and balances of a lesser amount which could influence the understanding of users of the financial statements we calculate a lower level of materiality for testing such areas. Specifically, given the importance of the distinction between revenue and capital for the Company, we also applied a separate testing threshold for income from investments, set at the higher of 5% of the revenue return before taxation and our Audit & Risk Committee reporting threshold. We have set a separate specific materiality in respect of related party transactions and Directors’ remuneration. We used our judgement in setting these thresholds and considered our experience and industry benchmarks for specific materiality. £0.14m Audit & Risk Committee reporting threshold We agreed with the Audit & Risk Committee that we would report to them all differences in excess of 5% of overall materiality in addition to other identified misstatements that warranted reporting on qualitative grounds, in our view. For example, an immaterial misstatement as a result of fraud. The revision to our overall materiality level noted above did not result in a requirement to revise our Audit & Risk Committee reporting threshold under the Firm’s methodology. £0.14m During the course of the audit, we reassessed initial materiality and found no reason to alter the basis of calculation used at year-end.Independent auditor’s report continued

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 59 Conclusions relating to going concern In auditing the financial statements, we have concluded that the Directors’ use of the going concern basis of accounting in the preparation of the financial statements is appropriate. Our evaluation of the Directors’ assessment of the Company’s ability to continue to adopt the going concern basis of accounting included: • Evaluating management’s method of assessing going concern, including consideration of market conditions and macro-economic uncertainties; • Assessing and challenging the forecast cashflows and associated sensitivity modelling used by the Directors in support of their going concern assessment; • Obtaining and recalculating management’s assessment of the Company’s ongoing maintenance of venture capital trust status; • Assessing the adequacy of the Company’s going concern disclosures included in the Annual Report and Financial Statements. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the Company’s ability to continue as a going concern for a period of at least 12 months from when the financial statements are authorised for issue. In relation to the Company’s reporting on how it has applied the UK Corporate Governance Code, we have nothing material to add or draw attention to in relation to the Directors’ statement in the financial statements about whether the Directors considered it appropriate to adopt the going concern basis of accounting. Our responsibilities and the responsibilities of the Directors with respect to going concern are described in the relevant sections of this report. Other information The other information comprises the information included in the Annual Report and Financial Statements other than the financial statements and our auditor’s report thereon. The Directors are responsible for the other information contained within the Annual Report and Financial Statements. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon. Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard. Opinions on other matters prescribed by the Companies Act 2006 In our opinion, the part of the Directors’ Remuneration Report to be audited has been properly prepared in accordance with the Companies Act 2006. In our opinion, based on the work undertaken in the course of the audit: • The information given in the Strategic Report and the Directors’ Report for the financial year for which the financial statements are prepared is consistent with the financial statements; and • The Strategic Report and the Directors’ Report have been prepared in accordance with applicable legal requirements.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 60 Matters on which we are required to report by exception In the light of the knowledge and understanding of the Company and its environment obtained in the course of the audit, we have not identified material misstatements in the Strategic Report or the Directors’ Report. We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion: • Adequate accounting records have not been kept by the Company, or returns adequate for our audit have not been received from branches not visited by us; or • The financial statements and the part of the Directors’ Remuneration Report to be audited are not in agreement with the accounting records and returns; or • Certain disclosures of Directors’ remuneration specified by law are not made; or • We have not received all the information and explanations we require for our audit; or • A corporate governance statement has not been prepared by the Company. Corporate governance statement We have reviewed the Directors’ statement in relation to going concern, longer-term viability and that part of the Corporate Governance Statement relating to the entity’s compliance with the provisions of the UK Corporate Governance Code specified for our review by the Listing Rules. Based on the work undertaken as part of our audit, we have concluded that each of the following elements of the Corporate Governance Statement is materially consistent with the financial statements or our knowledge obtained during the audit: • The Directors’ statement with regards to the appropriateness of adopting the going concern basis of accounting and any material uncertainties identified set out on page 39; • The Directors’ explanation as to its assessment of the Company’s prospects, the period this assessment covers and why the period is appropriate set out on pages 38 and 39; • The Directors’ statement on fair, balanced and understandable set out on page 55; • The Directors’ statement on whether it has a reasonable expectation that the Company will be able to continue in operation and meets its liabilities set out on page 39; • The Board’s confirmation that it has carried out a robust assessment of the emerging and principal risks set out on page 28; • The section of the Annual Report that describes the review of the effectiveness of risk management and internal control systems set out on pages 53 to 54; and • The section describing the work of the Audit & Risk Committee set out on pages 49 and 50. Responsibilities of Directors As explained more fully in the Directors’ Responsibilities Statement set out on page 55, the Directors 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 the Directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error. In preparing the financial statements, the Directors are responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the Directors either intend to liquidate the Company or to cease operations, or have no realistic alternative but to do so.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 61 Auditor responsibilities for the audit of the financial statements Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements. A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council’s website at: http://www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report. Extent to which the audit was considered capable of detecting irregularities, including fraud Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below. We assessed whether the engagement team collectively had the appropriate competence and capabilities to identify or recognise non- compliance with laws and regulations by considering their experience, past performance and support available. All engagement team members were briefed on relevant identified laws and regulations and potential fraud risks at the planning stage of the audit. Engagement team members were reminded to remain alert to any indications of fraud or non-compliance with laws and regulations throughout the audit. We obtained an understanding of the legal and regulatory frameworks that are applicable to the Company and the sector in which it operates, focusing on those provisions that had a direct effect on the determination of material amounts and disclosures in the financial statements. The most relevant frameworks we identified include: • Companies Act 2006; • Financial Conduct Authority (FCA) listing and Disclosure Guidance and Transparency Rules (DTR); • The principles of the UK Corporate Governance Code applied by the 2024 AIC Corporate Governance Code (the “AIC Code”); • Industry practice represented by the Statement of Recommended Practice: Financial Statements of Investment Trust Companies and Venture Capital Trusts (“the SORP”) issued in July 2022 and updated in December 2025; • The Company’s qualification as a Venture Capital Trust under section 274 of the Income Tax Act 2007; and • UK Generally Accepted Accounting Practice. We gained an understanding of how the Company is complying with these laws and regulations by making enquiries of management and those charged with governance. We corroborated these enquiries through our review of relevant correspondence with regulatory bodies and board meeting minutes. We assessed the susceptibility of the financial statements to material misstatement, including how fraud might occur, by meeting with management and those charged with governance to understand where it was considered there was susceptibility to fraud. This evaluation also considered how management and those charged with governance were remunerated and whether this provided an incentive for fraudulent activity. We considered the overall control environment and how management and those charged with governance oversee the implementation and operation of controls. In areas of the financial statements where the risks were considered to be higher, we performed procedures to address each identified risk. We identified a heightened fraud risk in relation to: • Valuation of unlisted investments; and • Management override of controls.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 62 Audit procedures performed in response to the risks relating to valuation of unlisted investments are set out in the section on key audit matters above, and audit procedures performed in response to the risk of management override of controls are included below. In addition to the above, the following procedures were performed to provide reasonable assurance that the financial statements were free of material fraud or error: • Reviewing minutes of meetings of those charged with governance for reference to: breaches of laws and regulation or for any indication of any potential litigation and claims; and events or conditions that could indicate an incentive or pressure to commit fraud or provide an opportunity to commit fraud; • Reviewing the level of and reasoning behind the Company’s procurement of legal and professional services; • Performing audit procedures over the risk of management override of controls, including testing of journal entries and other adjustments for appropriateness, performing unpredictability testing by expanding samples, recalculating the investment management fee and performance-related fee, evaluating the business rationale of significant transactions outside the normal course of business and assessing judgements made by management in their calculation of accounting estimates for potential management bias; • Completion of appropriate checklists and use of our experience to assess the Company’s compliance with the Companies Act 2006 and the Listing Rules; and • Agreement of the financial statement disclosures to supporting documentation. Our audit procedures were designed to respond to the risk of material misstatements in the financial statements, recognising that the risk of not detecting a material misstatement due to fraud is higher than the risk of not detecting one resulting from error, as fraud may involve intentional concealment, forgery, collusion, omission or misrepresentation. There are inherent limitations in the audit procedures performed and the further removed non-compliance with laws and regulations is from the events and transactions reflected in the financial statements, the less likely we would become aware of it. Other matters which we are required to address Following the recommendation of the Audit & Risk Committee, we were appointed by the Board on 7 August 2025 to audit the financial statements for the year ended 31 March 2026 and subsequent financial years. The period of our total uninterrupted engagement is one year, covering the year ended 31 March 2026. The non-audit services prohibited by the FRC’s Ethical Standard were not provided to the Company and we remain independent of the Company in conducting our audit. Our audit opinion is consistent with the additional report to the Audit & Risk Committee. Use of our report This report is made solely to the Company’s members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the Company’s members those matters we are required to state to them in an auditor’s report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the Company and the Company’s members as a body, for our audit work, for this report, or for the opinions we have formed.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 67 1. Accounting policies A summary of the principal accounting policies, all of which have been consistently applied throughout the year and the preceding year, is set out below. (a) Basis of accounting The financial statements have been prepared in accordance with applicable United Kingdom accounting standards, including Financial Reporting Standard 102 (“FRS 102”), with the Companies Act 2006 and the 2014 Statement of Recommended Practice, ‘Financial Statements of Investment Trust Companies and Venture Capital Trusts’ (“the SORP”) (updated in December 2025) issued by the Association of Investment Companies (“AIC”). The Company has early adopted these guidelines and is not aware of any material difference arising from this early adoption. The financial statements are prepared in sterling which is the functional and presentational currency of the Company and rounded to the nearest £000. The financial statements have been prepared on a going concern basis under the historical cost convention except investments which are stated at their fair value. The Directors performed an assessment of the Company’s ability to meet its liabilities as they fall due. In performing this assessment, the Directors took into consideration the uncertain economic outlook including: • the investments and liquid resources held by the Company; • the fact that the Company has no debt or capital commitments; • the ability of the Company to meet all of its liabilities and ongoing expenses from its assets, including its year-end cash balance; • revenue and operating cost forecasts for the forthcoming year; • the ability of third-party service providers to continue to provide services; and • potential downside scenarios including a fall in the valuation of the investment portfolio or levels of investment income. Based on this assessment, the Directors are confident that the Company will have sufficient funds to continue to meet its liabilities as they fall due for at least 12 months from the date of approval of the financial statements, and therefore determine the going concern basis to be appropriate. (b) Significant estimates and judgements Disclosure is required of judgements and estimates made by management in applying the accounting policies that have a significant effect on the financial statements. While estimates are based on best judgement using information and financial data available, the actual outcome may differ from these estimates. A price sensitivity analysis is provided in the other price risk sensitivity section of Note 18 on page 80. The key estimate in the financial statements is the determination of the fair value of the unlisted investments by the Directors as it significantly impacts the valuation of the unlisted investments at the balance sheet date. The fair valuation process involves estimates using inputs that are unobservable. The fair value of the unlisted investments at the balance sheet date was £93,438,000. The key judgement in the valuation of the unquoted investments process is the Directors’ determination of the appropriate application of the International Private Equity and Venture Capital (‘IPEV’) guidelines to each unlisted investment. The judgement applied in the selection of the methodology used for determining the fair value of each unlisted investment can have a significant impact upon the valuation. Notes to the financial statements

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 68 Notes to the financial statements continued (c) Valuation of investments Purchases and sales of investments are recognised in the financial statements at the date of transaction (trade date). As permitted by FRS 102 chapters 11 and 12, the Company’s investments are recorded at fair value at the point of acquisition and are measured at subsequent reporting dates at fair value, with any changes being recognised in profit or loss. The fair value of investments held at 31 March 2026 is £99,345,000 (31 March 2025: £103,231,000). In the case of investments quoted on a recognised stock exchange, fair value is established by reference to the closing bid price on the relevant date or the last traded price, depending on the convention of the exchange on which the investment is quoted. In the case of unquoted investments, fair value is established in accordance with IPEV guidelines by using measurements of value such as calibrating to the price of recent investment and earnings or revenue multiples; where no reliable fair value can be estimated using such techniques, unquoted investments are carried at cost subject to provision for impairment where necessary. This process is used for both the valuation of unquoted equity and debt investments. In the case of debt investments, debt, including both principal and any accrued interest is valued with reference to their recoverability upon eventual sale of the Company’s investment. The key assumption when using the price of a recent investment as an input to the valuation is that the price obtained remains a reasonable proxy for fair value for a period of time such that an enterprise value can be inferred and subsequently recalibrated where necessary to take account of changes to either the prevailing market conditions or performance of the investee. The price of a recent investment is not a default position for establishing fair value as at the measurement date and when this technique is employed, the resultant valuations are cross- checked for reasonableness by employing an alternative valuation technique. The key assumptions for the multiples approach are the selection of the most appropriate earnings or revenue measure (historic or forecast) and the selection of the multiple itself which may be influenced by the multiples achieved by a range of comparable companies in either private or public transactions. Gains and losses arising from changes in fair value of investments are recognised as part of the capital return within the income statement and allocated to the revaluation reserve. Transaction costs attributable to the acquisition or disposal of investments are charged to capital return within the income statement, in accordance with AIC SORP guidance. Investments are carried at fair value, which may reduce to nil where recoverability is considered remote. Such investments remain at nil fair value until realisation or formal insolvency, with movements recognised in the capital return (revaluation reserve) and any realised losses recognised in the capital reserve. (d) Cash and cash equivalents Cash and cash equivalents comprise cash balances and short-term deposits, including short-term highly liquid investments and money market funds readily convertible to known amounts of cash. (e) Income Dividends receivable on quoted equity shares are recognised on the ex-dividend date. Dividends receivable on the portfolio of quoted equity investments held for liquidity purposes are recognised on the date of receipt due to the nature of how this portfolio is managed. Dividends receivable on unquoted equity shares are recognised when the Company’s right to receive payment is established and there is no reasonable doubt that payment will be received. Fixed income returns on non-equity shares and debt securities are recognised on an effective interest rate basis, provided there is no reasonable doubt that payment will be received in due course.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 69 (f) Expenses All expenses are accounted for on an accruals basis. Expenses are charged to revenue return within the income statement except that: • expenses which are incidental to the acquisition or disposal of an investment are allocated to capital return as incurred; and • expenses are split and allocated partly to capital return where a connection with the maintenance or enhancement of the value of the investments held can be demonstrated, and accordingly the basic element of the investment management fee has been allocated 25% to revenue return and 75% to capital return, in order to reflect the Directors’ expected long-term view of the nature of the investment returns of the Company. The performance- related element of the investment management fee is charged 100% to capital return. (g) Revenue and capital The revenue column of the income statement includes all income and revenue expenses of the Company. The capital column includes realised and unrealised gains and losses on investments and that part of the investment management fee which is allocated to capital return. (h) Taxation UK corporation tax payable is provided on taxable profits at the current rate. The tax charge for the year is allocated between revenue return and capital return on the ‘marginal basis’ as recommended in the SORP. Provision is made for deferred taxation on all timing differences calculated at the current rate of tax relevant to the benefit or liability. (i) Dividends payable Dividends payable are recognised as distributions in the financial statements when the Company’s liability to make payment has been established. (j) Provisions A provision is recognised in the balance sheet when the Company has a legal or constructive obligation as a result of a past event and it is probable that an outflow of economic benefits will be required to settle the obligation. No provision is established where a reliable estimate of the obligation cannot be made. Provisions are allocated to revenue or capital depending on the nature of the circumstances. (k) Share capital account The share capital account represents the nominal value of all shares issued by the Company. (l) Share premium account The share premium account represents the value paid by shareholders for shares above the nominal value. (m) Capital redemption reserve The capital redemption reserve is a non-distributable reserve into which amounts are transferred following the redemption or purchase of a company’s own shares. (n) Revaluation reserve Changes in the fair value of investments are dealt with in this reserve.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 70 Notes to the financial statements continued (o) Capital reserve The following are accounted for in the capital reserve: gains or losses on the realisation of investments; the cost of repurchasing ordinary shares, including stamp duty and transaction costs; and other capital charges and credits charged to this account in accordance with the above policies. (p) Revenue reserve The revenue reserve comprises the retained earnings of a business from profits made in the current and prior periods. (q) Segmental reporting The Company has a single operating segment carrying out the investment activity of the Company. All venture investments are based in the UK. No further segmental analysis is provided as allowed by paragraph XIV of the SORP, due to the homogeneous nature of the trust’s investment activities. All income from operating segments is disclosed in Note 2. 2.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 71 The Manager receives a basic management fee, payable quarterly in advance, at the rate of 2.06% per annum of net assets calculated half-yearly as at 31 March and 30 September. The fee due on the value of liquid assets above the threshold of £20 million attracts a reduced rate of 1% per annum. The Manager bears the cost of the fees of Brewin Dolphin for managing the listed interest-bearing and equity portfolios. The Manager also provides administrative and secretarial services to the Company for an annualised fee as at 31 March 2026 of £74,000 per annum (linked to the movement in the CPI). This fee is included in other expenses (see Note 4). The Manager is entitled to receive an annual performance-related management fee. The fee is calculated on annual performance above the higher of the annual hurdle of 5% of opening NAV per share and the deficit to the high water mark total return brought forward (together, the ‘Excess Return’). The performance-related management fee is calculated at 14% of the Excess Return and the payment of the performance-related management fee in any one year is capped to 2.25% of the net asset value at the start of the year with the balance being deferred. The performance-related management fee due in respect of the year ended 31 March 2026 was nil (2025: £65,000). The total running costs of the Company, excluding performance-related management fees and any irrecoverable VAT thereon, are capped at 2.9% of its net assets and Mercia has agreed that any excess will be refunded by way of a reduction in its fees. 4.

There is no other unprovided deferred taxation. Approved venture capital trusts are exempt from tax on capital gains within the Company. Since the Directors intend that the Company will continue to conduct its affairs so as to maintain its approval as a venture capital trust, no current or deferred tax has been provided in respect of any capital gains or losses arising on the revaluation or disposal of investments.

Return per share The calculation of the return per share is based on the loss after tax for the year of £952,000 (2025: profit after tax £6,956,000) and on 152,736,203 (2025: 146,866,413) shares, being the weighted average number of shares in issue during the year. 8. Investments All investments are accounted for as fair value through profit or loss on initial recognition, therefore all gains and losses arising on these investments are reflected through the profit or loss. FRS 102, including subsequent amendments, requires an entity to classify fair value measurements using a fair value hierarchy that reflects the significance of the inputs used in making the measurements. The fair value hierarchy shall have the following classifications: • Level 1 – unadjusted quoted prices in an active market for identical assets or liabilities that the entity can access at the measurement date. • Level 2 – inputs other than quoted prices included within Level 1 that are observable (ie developed using market data) for the asset or liability, either directly or indirectly. • Level 3 – inputs are unobservable (ie for which market data is unavailable) for the asset or liability.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 75 The gains and losses in the above table have all been recognised in the income statement on page 63. Details of movements in the venture investment portfolio during the year is provided in the Investment portfolio section on page 15. At 31 March 2026 there were no commitments (31 March 2025: nil) in respect of investments approved by the Manager but not yet completed. Transactions shown as purchases and disposals above may differ from those reported in the Statement of Cash Flows. This can arise as a result of investment reorganisations, the conversion of convertible loan instruments, and the settlement of associated receivables and payables. For debt investments, interest is recognised as income only to the extent that it has been received, or is expected to be received, in accordance with the accounting policy set out in Note 1. Where loan stock interest does not meet the recognition criteria for investment income, it is instead reflected within the investment valuation, where supported by the overall valuation of the portfolio company, and is included within unrealised gains and losses on investments. Valuation methodology 31 March 2026 £000 31 March 2025 £000 Revenue multiple 63,138 54,473 Cost and price of recent investment (calibrated and reviewed for impairment) 26,215 20,514 Earnings multiple 4,085 12,612 Net assets – 30 93,438 87,629 The principal inputs used in the calibration exercise, and in valuation techniques based on multiples, include revenue, EBITDA and earnings multiples. These are derived by reference to the most recent financial performance of the portfolio company and the relevant multiples observed for comparable companies. Adjustments are made to reflect differences in scale, growth prospects, risk profile and quality of earnings. Revenue multiples are frequently applied, reflecting the nature of the Company’s portfolio which predominantly comprises growth-oriented and technology businesses that are not typically profitable in the earlier stages of development. Once an investee company reaches sufficient scale and sustained profitability, valuation approaches are more commonly based on EBITDA or earnings multiples. In applying comparable trading multiples to the valuation of equity instruments, the Company identifies appropriate sector valuation reports. These multiples are then adjusted to reflect factors such as illiquidity, marketability and other company-specific differences between the portfolio company and the selected public comparators. Where valuations are based on cost or the price of a recent investment, the Company undertakes a calibration process at each valuation date. This involves assessing the performance and progress of the investee relative to the original investment case, considering whether any key events or milestones have occurred that may indicate a change in value, and determining whether an alternative approach, such as a market-based multiple or discounted cash flow methodology, would be more appropriate. Consideration is also given to the circumstances surrounding the transaction where the investment price may not represent fair value, for example where there has been disproportionate dilution of existing shareholders or where market conditions at the time of investment no longer reflect those at the valuation date.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 76 Notes to the financial statements continued The Directors consider that, for each investment, the valuation methodology selected represents the most appropriate approach having regard to the nature and performance of the business, market conditions and the IPEV Guidelines, and provides a reliable estimate of fair value as at 31 March 2026. FRS 102 requires consideration of the sensitivity of fair value measurements to reasonably possible alternative assumptions. Approximately 28% of the Level 3 investments held in the portfolio, comprising investments valued using recent transaction price, discounted offer price, net assets or cost, is not subject to sensitivity analysis. For the remaining investments, comprising approximately 72% of the Level 3 investments held in the portfolio, the Directors have assessed the potential impact of changes in key valuation inputs, in particular revenue and earnings multiples. Sensitivity analysis has been performed on these investments and is summarised below: As at 31 March 2026 Valuation technique Fair value £000 Multiple range Weighted average multiple Change in input Change in fair value of investments £000 Change in NAV (pence per share) Revenue multiple 63,138 0.1x – 8.0x 3.3x + 10% 3,913 2.48 -10% (3,003) (1.90) Earnings multiple 4,085 2.5x – 9.2x 5.8x + 10% 652 0.41 -10% (551) (0.35) As at 31 March 2025 Valuation technique Fair value £000 Multiple range Weighted average multiple Change in input Change in fair value of investments £000 Change in NAV (pence per share) Revenue multiple 54,473 0.25x – 8.0x 4.5x + 10% 3,700 2.56 -10% (2,476) (1.71) Earnings multiple 12,612 4.0x – 8.0x 7.0x + 10% 1,280 0.89 -10% (1,416) (0.98) This illustrates that a 10% increase in the revenue and earnings multiples applied would result in an increase in the value of unquoted investments of £4,565,000 (2025: £4,980,000). Conversely, a 10% decrease in the multiples would reduce the value by £3,554,000 (2025: £3,892,000).

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 80 Notes to the financial statements continued 17. Net asset value per share The calculation of net asset value per share as at 31 March 2026 is based on net assets of £134,181,000 (2025: £130,109,000) divided by the 157,645,007 (2025: 144,514,326) ordinary shares in issue at that date. 18. Financial instruments The Company’s financial instruments comprise equity and interest-bearing investments, cash at bank, investments in money market funds and liquid resources including debtors and creditors. The Company holds financial assets in accordance with its investment policy of investing mainly in a portfolio of VCT-qualifying unquoted and AIM-quoted securities whilst holding a proportion of its assets in cash or near-cash investments in order to provide a reserve of liquidity. Fixed asset investments (see Note 8) are valued at fair value. For quoted investments this is either bid price or the latest traded price, depending on the convention of the exchange on which the investment is quoted. Unquoted investments are carried at fair value as determined by the Directors in accordance with current venture capital industry guidelines. The fair value of all other financial assets and liabilities is represented by their carrying value in the balance sheet, due to the short term nature of these instruments. In carrying on its investment activities, the Company is exposed to various types of risk associated with the financial instruments and markets in which it invests. The most significant types of financial risk facing the Company are market risk, credit risk and liquidity risk. The Company’s approach to managing these risks is set out below together with a description of the nature and amount of the financial instruments held at the balance sheet date. Market risk The Company’s strategy for managing investment risk is determined with regard to the Company’s investment objective, as outlined in the Strategic Report on page 24. The management of market risk is part of the investment management process and is a central feature of venture capital investment. The Company’s portfolio is managed in accordance with the policies and procedures described in the Corporate Governance statement on pages 47 to 54, having regard to the possible effects of adverse price movements, with the objective of maximising overall returns to shareholders. Investments in unquoted companies, by their nature, usually involve a higher degree of risk than investments in companies quoted on a recognised stock exchange, though the risk can be mitigated to a certain extent by diversifying the portfolio across business sectors and asset classes. The overall disposition of the Company’s assets is monitored by the Board on a quarterly basis. Details of the Company’s investment portfolio at the balance sheet date are set out on pages 15 to 17. An analysis of investments between debt and equity instruments is given in Note 8. 4.4% (31 March 2025: 12.0%) by value of the Company’s net assets comprises equity securities listed on regulated stock exchanges. A 5% increase in the bid price of these securities as at 31 March 2026 would have increased net assets and the total return for the year by £295,000 (31 March 2025: £780,000); a corresponding fall would have reduced net assets and the total return for the year by the same amount. Other price risk sensitivity 69.5% (31 March 2025: 67.3%) by value of the Company’s net assets comprises investments in unquoted companies held at fair value. A sensitivity analysis is provided in Note 8 which recognises that the valuation methodologies employed involve subjectivity in the selection of the key inputs, as described in the valuation policy on page 24. Although the Directors believe that the estimates of fair value are appropriate, the use of different methodologies or assumptions regarding the inputs could lead to different measurements of fair value.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 81 Interest rate risk Some of the Company’s financial assets are interest-bearing, of which some are at fixed rates and some variable. As a result, the Company is exposed to fair value interest rate risk due to fluctuations in the prevailing levels of market interest rates. (a) Fixed rate investments The table below summarises weighted average effective interest rates for the Company’s fixed rate interest-bearing financial instruments: 31 March 2026 31 March 2025 Total fixed rate portfolio £000 Weighted average interest rate % Weighted average period for which rate is fixed Years Total fixed rate portfolio £000 Weighted average interest rate % Weighted average period for which rate is fixed Years Fixed-rate investments in unquoted companies 11,838 9.6% 2.5 9,788 10.4% 1.9 Although the Company holds investments in loan stocks that pay interest, the Board does not consider it appropriate to assess the impact of interest rate changes in isolation upon the value of the unquoted investment portfolio, as interest rate changes are only one factor affecting the market price movements that are discussed above under market price risk. (b) Floating rate investments The Company’s floating rate investments comprise floating-rate loans to unquoted companies and cash and cash equivalents. The benchmark rate which determines the rate of interest receivable is the UK bank base rate for cash and cash equivalents, which was 3.75% at 31 March 2026 (31 March 2025: 4.5%). It is considered that an increase or decrease of 100 basis points in interest rates as at the reporting date would not have a significant effect on the Company’s net assets or total return for the year. The amounts held in floating rate investments at the balance sheet date were as follows: 31 March 2026 £000 31 March 2025 £000 Cash and cash equivalents 34,858 24,862 34,858 24,862

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 82 Notes to the financial statements continued Credit risk Credit risk is the risk that a counterparty to a financial instrument will fail to discharge an obligation or commitment that it has entered into with the Company. The Manager and the Board carry out a regular review of counterparty risk. The carrying values of financial assets represent the maximum credit risk exposure at the balance sheet date. At 31 March 2026 the Company’s financial assets exposed to credit risk comprised the following: 31 March 2026 £000 31 March 2025 £000 Fixed-rate investments in unquoted companies (above) 11,838 9,788 Cash and cash equivalents 34.858 24,862 Accrued dividends and interest receivable 101 115 46.797 34,765 Credit risk relating to loans and preference shares in unquoted companies is considered to be part of market risk. The balances included within unquoted loan investments related to loans which were past due as at 31 March 2026 is nil (31 March 2025: nil). The exposure to credit risk on accrued income is mitigated by performing loan affordability evaluations on investee companies as part of the investment due diligence process. Those assets of the Company which are traded on recognised stock exchanges are held on the Company’s behalf by a third party custodian (a nominee company of Brewin Dolphin Limited). Bankruptcy or insolvency of a custodian could cause the Company’s rights with respect to securities held by the custodian to be delayed or limited. Credit risk arising on transactions with brokers relates to transactions in quoted securities awaiting settlement. Risk relating to unsettled transactions is considered to be low due to the short settlement period involved and the high credit quality of the brokers used. The Board further mitigates the risk by monitoring the quality of service provided by the brokers. The Company’s cash and cash equivalents are maintained with major banks of high creditworthiness or highly rated low volatility money market funds (see Note 13 for further detail). There were no significant concentrations of credit risk to counterparties at 31 March 2026 or 31 March 2025. Liquidity risk The Company’s financial assets include investments in unquoted equity securities which are not traded on a recognised stock exchange and which generally may be illiquid. As a result, the Company may not be able to realise some of its investments in these instruments quickly at an amount close to their fair value in order to meet its liquidity requirements, or to respond to specific events such as a deterioration in the creditworthiness of any particular issuer. The Company’s cash and cash equivalents investments are considered to be readily realisable as they are of high credit quality as outlined above.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 83 The Company’s liquidity risk is managed on a continuing basis by the Manager in accordance with policies and procedures laid down by the Board. The Company’s overall liquidity risks are monitored on a quarterly basis by the Board. The Company maintains sufficient cash and cash equivalents to pay accounts payable and accrued expenses. At 31 March 2026 these investments were valued at £34,858,000 (31 March 2025: £36,974,000). 19. Contingencies At 31 March 2026 contingent assets not recognised in the financial statements in respect of potential deferred proceeds from the sale of investee companies amounted to approximately £202,000 (31 March 2025: £794,000). The extent to which these amounts will become receivable in due course is dependent on future events. The Company had no contingent liabilities at 31 March 2026 or 31 March 2025. 20. Related party transactions Fees payable during the year to the Directors and their interest in shares of the Company are disclosed within the Directors’ Remuneration Report on page 44. There were no amounts outstanding and due to the Directors as at 31 March 2026 (31 March 2025: nil). Fees charged by the Manager to the Company are disclosed in Note 3. As detailed in the Directors’ report on page 41, the Manager also charged investee companies £437,000 (2025: £404,000) of arrangement fees and £343,000 (2025: £345,000) of directors’ and monitoring fees in the year. 21. Post balance sheet events After the year end, on 2 April 2026, the Company issued 20,180,102 ordinary shares for a net consideration of £17,638,000 as a result of the prospectus share offer launched during the year ended 31 March 2026. On 1 April 2026, the Company invested £973,000 in a new portfolio company, Flok Health, a digital healthcare company providing AI-enabled physiotherapy services, primarily focused on musculoskeletal conditions. On 15 April 2026, the Company invested £973,000 in a new portfolio company, Fifth Dimension AI, a software company providing decision-intelligence tools for the real estate and real-assets sector. Since the year end, the Company has invested £1,457,000 of follow-on capital across three existing portfolio companies. Since the year end, the Company has fully exited four AIM-listed venture holdings (CelLBxHealth (formerly Angle), Netcall, Pebble Beach Holdings and Velocity Composites) for total proceeds of £864,000, compared with a carrying value at 31 March 2026 of £680,000 and a cost of £960,000. Since the year end, the Company has also partially exited its AIM-listed holdings in Eco Animal Health and Synectics, for proceeds of £78,000, compared with a carrying value at 31 March 2026 of £81,000 and an original cost of £178,000.

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 84 Alternative performance measure or APM APMs are not prescribed by accounting standards but are industry specific performance measures which help users of the annual accounts and financial statements to better interpret and understand performance. Some of the terms in this glossary have been identified as APMs. Annualised tax-free dividend yield (APM) The sum of dividends proposed or paid in respect of the last 12 months as at a given date expressed as a percentage of the net asset value per share at the start of the period. We use this measure as it shows the dividend income receivable by shareholders over a 12 month period expressed as a theoretical yield based on acquiring a single share at the NAV per share at the start of the period. The dividend yield as at 31 March 2026 is calculated by dividing the dividend per share paid or proposed over the preceding 12 months of 4.5 pence (2025: 4.5 pence) by the NAV per share at the start of the period of 90.0 pence (2025: 89.3 pence) giving a result of 5.0% (2025: 5.0%). Cumulative return per share (APM) The sum of the published NAV per share plus cumulative dividends paid per share since the Company was launched. We use this measure as it enables comparisons to be made between different VCTs over the whole life of each fund. The cumulative return per share for the Company as at 31 March 2026 comprises the NAV per share of 85.1 pence (2025: 90.0 pence) plus the cumulative dividends paid of 126.6 pence (2025: 122.1 pence) giving a result of 211.7 pence per share (2025: 212.1 pence per share). Cumulative dividends paid per share The total amount of shareholder dividend distributions paid per share since the Company was launched. Distributable reserves The sum of the capital reserve, revenue reserve and that part of the revaluation reserve which is related to readily realisable investments. Ex-dividend date The date immediately preceding the record date for a given dividend. Shareholders who acquire their shares on or after the ex-dividend date will not be eligible to receive the relevant dividend. Gain/loss on disposal of investments The profit or loss on the sale of an investment during the year calculated by reference to the proceeds received on sale of the investment less the valuation of the investment at the last annual report date. Glossary of terms

Northern 3 VCT PLC Annual Report and Financial Statements 31 March 2026 Strategic report Governance Financial statements Introduction 85 NAV total return (APM) The theoretical return to a shareholder over a given period based on acquiring shares at the start of the period at the latest published NAV per share then utilising the proceeds of each dividend paid during the period to acquire further shares at the latest published NAV per share as at each ex-dividend date. We use this measure as it enables comparisons to be drawn against an investment index in order to benchmark performance.
