Dear Shareholder

NCC Group plc's 2026 Annual General Meeting

I am pleased to invite you to attend the 2026 Annual General Meeting (AGM) of the Company to be held at the offices of NCC Group plc, XYZ Building, 2 Hardman Boulevard, Spinningfields, Manchester M3 3AQ, at 1.00 pm on Tuesday 3 March 2026.

The primary focus of the AGM will be on the formal business set out in the Notice of Meeting (the "Notice"). The formal Notice of AGM is set out on pages 5 and 6 of this document and the explanatory notes on each resolution to be considered at the AGM appear on pages 2 to 4 of this document.

Action to be taken

The business of the meeting will be conducted on a poll. While the Company is looking forward to welcoming our shareholders to our AGM, shareholders are encouraged to submit their voting instructions and Proxy Form as soon as possible, even if they might intend to attend the AGM in person.

The Company's Registrar, Equiniti, must receive the completed Proxy Form, at the address on the form, by no later than 1.00 pm on Friday 27 February 2026. Alternatively, you can vote using our CREST proxy voting service by following the procedures set out in the CREST Manual, or if you are an institutional investor you may be able to appoint a proxy electronically via the Proxymity platform. You will still be able to vote on the day of the AGM if you attend the AGM in person, but if you have already submitted a Proxy Form, this will only be necessary if you intend to change the voting instructions given on your Proxy Form. Further details relating to voting by proxy are set out in the notes to the Notice on pages 7 to 9 of this document.

Recommendation

The Directors of the Company (the "Directors") believe that the resolutions set out in the Notice are likely to promote the success of the Company and are in the best interests of the Company and its shareholders. Accordingly, the Directors unanimously recommend you vote in favour of the resolutions set out on pages 5 to 6, as they intend to do in respect of their own beneficial shareholdings in the Company.

The Board would like to take this opportunity to thank all shareholders for their continued support.

Yours faithfully,

Chris Stone

Chair

Explanatory notes on the resolutions which we will be proposing at the AGM

Resolutions 1 to 13 (inclusive) and Resolution 18 will be proposed as ordinary resolutions. This means that, for each of those resolutions to be passed, more than 50% of the votes cast must be in favour of the resolution. Resolutions 14 to 17 (inclusive) and Resolution 19 will be proposed as special resolutions. This means that, for each of those resolutions to be passed, at least 75% of the votes cast must be in favour of the resolution.

Resolution 1: Receiving the Annual Report and Accounts

The Directors are required to present the Annual Report and Financial Statements for the financial year ended 30 September 2025, together with the Strategic Report and the reports of the Directors and auditor to shareholders at the AGM, all of which are contained within the Company's Annual Report and Accounts 2025 (the "2025 Annual Report"), which is available online at www.nccgroupplc.com/investorrelations/results-media/.

Resolution 2: Approving the Directors' Remuneration Report

The Directors' Remuneration Report is included in full on pages 81 to 93 of the 2025 Annual Report and provides details of the remuneration paid to the Directors in respect of the financial year ended 30 September 2025.

In accordance with the Companies Act 2006 (the "Companies Act"), the approval of the Directors' Remuneration Report is an advisory vote only and the Directors' entitlement to receive remuneration is not conditional thereon. This resolution and vote are a means of providing shareholder feedback to the Board on the implementation of the Directors' Remuneration Policy which was approved by shareholders at the Annual General Meeting held on 28 January 2025.

Resolution 3: Declaring a final dividend

Final dividends are to be approved by shareholders. However, they cannot be more than the amount the Board recommends. The Board is recommending a final dividend of 3.15p per ordinary share for the financial year ended 30 September 2025. If approved, the final dividend will be paid on 10 April 2026 to shareholders on the register at close of business on Friday 13 March 2026.

Resolutions 4 and 5: Reappointment and remuneration of the auditor

The auditor of the Company is required to be appointed or reappointed at each AGM at which accounts are presented. The Board, on the recommendation of the Audit Committee, recommends the reappointment of PricewaterhouseCoopers LLP (PwC) as auditor of the Company (to hold office until the next such meeting) and, accordingly, Resolution 4 proposes such reappointment. An assessment of the effectiveness, independence and objectivity of the auditor has been undertaken by the Audit Committee and details of the assessment can be found on page 75 of the 2025 Annual Report. The Board confirms that: (1) the recommendation is free from influence by a third party; and (2) no contractual term of the kind mentioned in Article 16(6) of the EU Regulation 537/2014 has been imposed on the Company.

In accordance with normal practice, Resolution 5 proposes that the Audit Committee, for and on behalf of the Directors, be authorised to determine the level of the auditor's remuneration.

Resolutions 6 to 12: Re-election of Directors

In accordance with the UK Corporate Governance Code (the "Code"), all of the Directors will stand for re-election at the AGM. No Directors have been appointed by the Board since the previous AGM and therefore no Directors are required to submit themselves for election at the AGM under the Company's Articles of Association (the "Articles").

Biographical details of each Director standing for re-election can be found on pages 62 and 63 of the 2025 Annual Report together with their skills and experience which support the reasons why their contributions are, and continue to be, important to the Company's long-term sustainable success.

The Board supports the re-election of each Director, as it believes that the particular knowledge and experience of each Director, as described in their biographies on pages 62 to 63 of the 2025 Annual Report, assist in ensuring that the Board has an appropriate balance of skills and experience for the requirements of the business. The Board has confirmed, following a performance review, that each of the Directors standing for re-election continues to perform effectively and demonstrates commitment to their role. Details of the Board performance review are set out within the 2025 Annual Report. Their independence was determined by reference to the relevant provisions of the Code. The Board has considered whether each of the Non-Executive Directors is free of any relationship that could materially interfere with the exercise of their independent judgement and has determined that each Non-Executive continues to be considered independent.

Resolution 13: Granting the Directors authority to allot shares

Under section 551 of the Companies Act, the directors of a company are not permitted to allot shares (or grant certain rights over shares) unless authorised to do so by shareholders.

Resolution 13 renews a similar authority given at the last AGM and is in two parts.

The Investment Association ("IA") share capital management guidelines on directors' authority to allot shares state that its members will permit, and treat as routine, resolutions seeking authority to allot shares representing up to two-thirds of the company's issued share capital, provided that any authority to allot shares representing in excess of one-third of the company's issued share capital should only be used to allot shares pursuant to a fully pre-emptive offer (including a rights issue).

In line with guidance issued by the IA, if passed, paragraph (a) of Resolution 13 will authorise the Directors to allot shares in the Company (and to grant rights to subscribe for, or to convert any security into, shares in the Company) up to an aggregate nominal amount of £1,050,759.00 (representing 105,075,900 ordinary shares). This amount represents approximately one-third of the issued ordinary share capital of the Company as at 10 December 2025 (being the latest practicable date before the publication of this document).

In addition, if passed, paragraph (b) of Resolution 13 will authorise the Directors to allot ordinary shares in the Company (and to grant rights to subscribe for, or to convert any security into, ordinary shares in the Company) in connection with a rights issue only up to a further aggregate nominal amount of £1,050,759.00 (representing 105,075,900 ordinary shares). This amount represents approximately one-third of the issued ordinary share capital of the Company as at 10 December 2025 (being the latest practicable date before the publication of this document).

As at the date of this document, no ordinary shares are held by the Company in treasury.

The Directors have no current intention of allotting new ordinary shares other than in relation to the Company's share schemes. However, the Directors consider that it is in the best interests of the Company to have the authorities available so that they have the maximum flexibility to allot shares or grant rights without the need for a general meeting should they determine that it is appropriate to do so to respond to market developments or to take advantage of business opportunities as they arise. The Board recommends that this authority be renewed.

If given, these authorities will expire on the earlier of the conclusion of the Company's next AGM, or on 3 June 2027. It is the Directors' intention to renew the allotment authority each year.

Resolutions 14 and 15: Disapplication of pre-emption rights

Generally, if the Directors wish to allot new shares or other equity securities (within the meaning of section 560 of the Companies Act) for cash or sell treasury shares for cash, then under the Companies Act they must first offer such shares or securities to shareholders in proportion to their existing holdings. These statutory pre-emption rights may be disapplied by shareholders.

In accordance with the Pre-Emption Group's Statement of Principles on Disapplying Pre-Emption Rights ("Statement of Principles"), Resolutions 14 and 15, which will be proposed as special resolutions, will enable the Directors to allot equity securities for cash or sell treasury shares for cash up to a maximum aggregate nominal amount of £2,101,518.00 without first offering them to shareholders pro rata to their existing holdings.

The powers proposed under Resolution 14 will be limited to allotments or sales of ordinary shares:

• (a) up to an aggregate nominal amount of (i) £2,101,518.00 in connection with a rights issue or (ii) £1,050,759.00 in connection with an open offer or other pre-emptive offer, in each case to ordinary shareholders and to holders of other equity securities (if required by the rights of those securities or the Directors otherwise consider necessary), but (in accordance with normal practice) subject to such exclusions or other arrangements, such as for fractional entitlements and overseas shareholders, as the Directors consider necessary;
• (b) in any other case, up to an aggregate nominal amount of £315,227.00 (representing 31,522,700 ordinary shares). This amount represents approximately 10% of the issued ordinary share capital of the Company as at 10 December 2025 (being the latest practicable date before the publication of this document); and
• (c) up to 2% for a follow-on offer which the Directors determine to be a kind contemplated in the Statement of Principles.

If given, the authority granted under Resolution 14 will expire on the earlier of the conclusion of the Company's next AGM, or on 3 June 2027. It is the Directors' intention to renew this authority each year.

The powers proposed under Resolution 15 will be limited to allotments or sales of ordinary shares:

• (a) up to an aggregate nominal amount of £315,227.00 (representing 31,522,700 ordinary shares). This amount represents approximately 10% of the issued ordinary share capital of the Company as at 10 December 2025 (being the latest practicable date before the publication of this document);
• (b) may be used only for the purposes of financing (or refinancing, if such refinancing occurs within 12 months of the original transaction) a transaction which the Directors determine to be an acquisition or other capital investment of a kind contemplated by the Statement of Principles most recently published by the Pre-Emption Group prior to the date of this Notice; and

(c) up to an aggregate nominal amount of £63,045.58 (which represents approximately 2% of the issued ordinary share capital of the Company) for a follow-on offer which the Directors determine to be a kind contemplated in the Statement of Principles.

If given, the authority granted under Resolution 15 will expire on the earlier of the conclusion of the Company's next AGM, or on 3 June 2027. It is the Directors' intention to renew this authority each year.

Resolution 16: Authority to purchase own shares

The Directors believe it is in the interests of the Company and its shareholders to have the flexibility to purchase its own shares and this resolution seeks authority from shareholders to do so.

Resolution 16, which will be proposed as a special resolution, renews a similar authority given at the last AGM. On 21 October 2025, as part of its strategy and trading update, the Company announced its intention to commence a share buyback programme in light of the strength of the Company's balance sheet and reflecting the Directors' confidence in the future prospects of the Group using the existing buyback authority from the Company's last AGM. The Directors may determine to undertake a share buyback programme using the general AGM authority in each year including under the authority sought pursuant to Resolution 16. The Directors will take into account factors including the financial resources of the Company, the Company's share price and future funding opportunities when deciding whether to undertake any share buyback programmes. The Directors would only use the authority under this Resolution 16 if they believed that to do so would be a prudent use of the Company's cash resources and would result in an increase in earnings per share and promote the success of the Company for the benefit of its shareholders as a whole. If any purchases of ordinary shares are made pursuant to this authority, it is intended that such ordinary shares will either be cancelled, held in treasury or used to satisfy options exercised under the Company's share schemes, in each case in accordance with the provisions of the Companies Act. While held in treasury, the shares would not be entitled to receive any dividend or dividend equivalent (apart from any issue of bonus shares) and would have no voting rights. The Directors will have regard to institutional shareholder guidelines which may be in force at the time of any such purchase, holding or resale of shares held in treasury. Any purchases of ordinary shares would be by means of market purchases on the London Stock Exchange.

In line with the guidelines published by the Investment Association, this resolution is limited to 31,522,700 ordinary shares, representing approximately 10% of the issued equity share capital of the Company as at 10 December 2025 (being the latest practicable date prior to publication of this document). The authority also sets minimum and maximum prices at which shares may be bought. The renewed authority will remain in force until the earlier of the conclusion of the Company's next AGM, or 3 June 2027. The Directors intend to seek renewal of this power at each AGM.

The total number of options to subscribe for ordinary shares for all share schemes of the Company which were outstanding as at 10 December 2025 (being the latest practicable date prior to publication of this document) was 12,022,632, which represents approximately 3.81% of the Company's issued share capital and would represent 4.24% of the Company's issued share capital if the full authority to repurchase ordinary shares, as proposed by Resolution 16, was exercised.

As at 10 December 2025 (being the latest practicable date prior to publication of this document), the Company holds no shares in treasury and there are no warrants outstanding over any ordinary shares in the Company.

Explanatory notes on the resolutions which we will be proposing at the AGM continued

Resolution 17: Notice of general meetings

Resolution 17 enables the Company to hold general meetings (other than AGMs) on 14 clear days' notice. The Companies Act provides that the minimum notice period required for general meetings of the Company is 21 clear days unless shareholders approve a shorter notice period, which cannot, however, be less than 14 clear days. The Articles currently permit such shorter notice period, but this resolution is required in order to comply with the Companies (Shareholders' Rights) Regulations 2009.

In accordance with the Companies Act, the Company must make a means of electronic voting available to all shareholders for that meeting in order to be able to call a general meeting on less than 21 clear days' notice. The Directors do not have any current intention to exercise this authority but consider it appropriate to ensure that the Company has the appropriate flexibility to respond to all eventualities.

If passed, the resolution will be effective until the Company's next AGM, when it is intended that a similar resolution will be proposed.

AGMs will continue to be held on at least 21 clear days' notice.

Resolution 18: Political donations

Resolution 18 deals with political donations. Under the Companies Act, political donations to any political parties, independent election candidates or political organisations or the incurring of political expenditure are prohibited unless authorised by shareholders in advance. What constitutes a political donation, a political party, a political organisation or political expenditure is not easy to decide, as these terms are widely defined in the Companies Act. Normal business activities and expenditure which might not be thought to be political expenditure or a political donation to a political organisation in the usual sense may fall within the restrictions of the Companies Act. For example, sponsorship, subscriptions, payment of expenses, paid leave for employees fulfilling public duties and support for bodies representing the business community in policy review or reform may fall within this.

It is not the Company's policy to make donations to political parties, or to make other political donations within the normal meaning of that expression, and the Directors have no intention of changing that policy. Therefore, notwithstanding that the Company has not made a political donation in the past and has no intention either now or in the future of making any political donation or incurring any political expenditure in respect of any political party, political organisation or independent election candidate, the Board has decided to put forward Resolution 18. The resolution does not purport to authorise any particular donation or expenditure, but is expressed in general terms, as required by the Companies Act, and will allow the Company to support the community and put forward its views to wider business and government entities without running the risk of being in inadvertent breach of the law. The authority will not be used to make political donations within the normal meaning of that expression. As permitted under the Companies Act, Resolution 18 also covers any political donations made, or political expenditure incurred, by any subsidiaries of the Company, in each case up to an aggregate limit of £75,000. This authority will expire at the end of the next AGM of the Company.

Resolution 19: Adoption of new Articles of Association

The Board is proposing that the Company adopt new Articles of Association (the "New Articles") in place of the current Articles of Association (the "Current Articles") which were adopted in September 2019.

The principal changes in the New Articles are summarised below. They are intended to reflect developments in law, regulation and market practice, and to provide additional flexibility where this is considered appropriate. In addition, the Company has taken the opportunity to incorporate amendments of a more minor, technical or clarifying nature, which are not summarised below. These seek to modernise the language in the document and clarify how certain provisions should operate.

(a) Dividends (article 130)

The New Articles give the Board greater flexibility to determine the appropriate method(s) by which it pays dividends to shareholders. This flexibility will help the Board take account of developments in market practice and keep down the administrative costs of making payments.

(b) Untraced shareholders (article 31)

The process of selling shares belonging to shareholders who remain untraced for a prolonged period has been modernised in the New Articles to bring it more into line with current market practice and to balance the administrative burden on the Company with the need to safeguard shareholder rights. The time period for engaging the Company's powers of sale in relation to the shares of such untraced shareholders has been reduced from twelve years to six years, and the proceeds of the sale of such shares will be forfeited by the former shareholder, with no further right to claim the proceeds from the Company (for the Board to use as they think fit). As such, consequential amendments have also been made to article 143 (unclaimed dividends) for consistency.

(c) Right to refuse registration (article 36)

The New Articles give the Board greater flexibility to the Board to refuse registration in a wider variety of circumstances to take account of developments in market practice. The New Articles allow for the Board to refuse registration of uncertificated shares in accordance with the uncertificated securities rules. The New Articles also allow the Board to refuse registration of an allotment or transfer of shares in favour of more than four joint allottees or transferees.

A marked-up version of the New Articles, showing the changes against the Current Articles, is available on the Company's website and will be available for inspection at the meeting.

Notes

• 1. In order to attend and vote at the Annual General Meeting (AGM) you must comply with the procedures set out in these notes by the dates specified in this Notice and accompanying notes.
• 1. Any member entitled to attend and vote at the AGM is entitled to appoint one or more proxies to exercise any or all of their rights to attend, speak and vote at the AGM. A form to be used for appointing a proxy or proxies for this AGM will be sent to you (the "Proxy Form"). Please complete and return the Proxy Form whether or not you intend to attend the AGM in person. The appointment of a proxy, including by return of the Proxy Form, will not prevent you from attending and voting at the AGM if you so wish. You can appoint the Chair of the AGM to act as your proxy or ask one or more persons of your choice to be your proxy. Your proxy does not have to be a shareholder of the Company. There are notes on the Proxy Form explaining how you should complete it.
• 1. Voting on all resolutions will be conducted by way of a poll, rather than on a show of hands. This is a more transparent method of voting as shareholders' votes are counted according to the number of shares registered in their names. The total voting rights in the Company as at 10 December 2025 (being the latest practicable date prior to publication of this document) was 315,227,905.
• 1. To be valid, the completed Proxy Form must be received by the Company's Registrar, Equiniti, by no later than 1.00 pm on Friday 27 February 2026 (or, if the AGM is adjourned, no later than 48 hours (excluding any part of a day that is not a working day) before the time of any adjourned meeting) and should be addressed to Freepost RTHJ-CLLL-KBKU, Equiniti, Aspect House, Spencer Road, Lancing BN99 8LU.
• 1. Arrangements for the appointment of a proxy and proxy instructions will be made available to all members who are registered in the register of members of the Company at the close of business on Friday 27 February 2026 (or, if the AGM is adjourned, close of business on the date which is two working days before the date of the adjourned meeting). If you have any questions in relation to your proxy appointment, please contact the Company's Registrar, Equiniti, on +44 (0)371 384 2679. If calling from outside the UK, please ensure the country code is used. Lines are open 8.30 am to 5.30 pm Monday to Friday excluding public holidays in England and Wales.
• 1. CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the AGM and any adjournment(s) thereof by using the procedures described in the CREST Manual. CREST personal members or other CREST sponsored members, and those CREST members who have appointed a voting service provider(s), should refer to their CREST sponsor or voting service provider(s), who will be able to take the appropriate action on their behalf.

In order for a proxy appointment or instruction made using the CREST service to be valid, the appropriate CREST message (a "CREST Proxy Instruction") must be properly authenticated in accordance with CREST's specifications and must contain the information required for such instructions, as described in the CREST Manual, which can be viewed at www.euroclear.com. The message, regardless of whether it constitutes the appointment of a proxy or an amendment to the instruction given to a previously appointed proxy, must, to be valid, be transmitted so as to be received by the issuer's agent (ID RA19) by 1.00 pm on Friday 27 February 2026 (or, if the AGM is adjourned, no later than

48 hours (excluding any part of a day that is not a working day) before the time of any adjourned meeting). For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp applied to the message by the CREST Applications Host) from which the issuer's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.

CREST members and, where applicable, their CREST sponsors or voting service providers should note that there are no special procedures in CREST for any particular messages. Normal system timings and limitations will therefore apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST personal member or sponsored member or has appointed a voting service provider(s), to procure that their CREST sponsor or voting service provider(s) take(s)) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In this connection, CREST members and, where applicable, their CREST sponsors or voting service providers are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings.

The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.

If you are an institutional investor you may be able to appoint a proxy electronically via the Proxymity platform, a process which has been agreed by the Company and approved by the Company's Registrar. For further information regarding Proxymity, please go to www.proxymity.io. Your proxy must be lodged by 1.00 pm on Friday 27 February 2026 (or, if the AGM is adjourned, no later than 48 hours (excluding any part of a day that is not a working day) before the time of any adjourned meeting) in order to be considered valid. Before you can appoint a proxy via this process you will need to have agreed to Proxymity's associated terms and conditions. It is important that you read these carefully as you will be bound by them and they will govern the electronic appointment of your proxy.

• 1. You may not use any electronic address provided either in this Notice or any related documents (including the Proxy Form) to communicate with the Company for any purposes other than those expressly stated.
• 1. The right of members to vote at the AGM is determined by reference to the Company's register of members (the "Register"). The Company has set a time and date for eligibility to attend the AGM. This year, only those shareholders registered at the close of business on Friday 27 February 2026 will be eligible to attend and vote at this AGM in respect of the number of shares registered in their name at that time. We will disregard changes to entries on the Register after close of business on Friday 27 February 2026 for this purpose.

If the AGM were to be adjourned for any reason, then only those shareholders registered in the Register at the close of business on the day which is two working days prior to the day fixed for the adjourned meeting will be eligible to attend and vote at the adjourned meeting.
