Arrangements for the 2021 Annual General Meeting (AGM) to be held at 2.00 pm on Thursday 4 November 2021

Following the government's announcement in July 2021, the Board notes that as of 19 July 2021, the remaining restrictions on social contact arising from the Covid-19 pandemic have been lifted. However, the public is being urged to exercise caution and the Board notes the increase in infections since the remaining restrictions were lifted. Although the Company is not expecting to be legally restricted in terms of attendance at the AGM, the Board remains committed to protecting the health and wellbeing of its shareholders and of the general public. Therefore, it is regrettably the opinion of the Board that due to the increase in the number of Covid-19 cases reported in the UK, shareholders should not physically attend the AGM. Accordingly, the Board strongly urges shareholders to consider whether travelling to and attending the AGM would be necessary under the current circumstances. In any event, attendees may be required to wear face coverings and will be required to keep a distance between themselves and other attendees.

The Company will arrange for the AGM to be convened with the minimum necessary quorum, to conduct the necessary business of the AGM. The Company therefore strongly encourages all shareholders to appoint the Chair of the meeting as their proxy and to submit their voting instructions electronically in advance of the meeting, in accordance with the instructions contained in the Notice of AGM.

The Board recognises that the AGM provides an important opportunity to engage with shareholders. Therefore, the Company will ensure that shareholders can submit any questions in writing prior to the AGM. Shareholders may submit a question, by writing to investor_relations@nccgroup.com with details of their name, shareholding and question by 2.00 pm on 2 November 2021. Only questions from registered shareholders of the Company will be accepted.

The result of the poll vote will be made available as soon as possible after the meeting on our website.

We hope all our shareholders will understand the need for this restriction in the interests of the health and wellbeing of our employees and our shareholders themselves.

NCC Group plc's 2021 Annual General Meeting

I am pleased to invite you to attend the 2021 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 2.00 pm on Thursday 4 November 2021.

The formal notice of AGM (the 'Notice') is set out on pages 5 and 6 and the explanatory notes on each resolution to be considered at this year's AGM appear on pages 2 to 4.

Action to be taken

Whether or not you intend to come to the AGM, please complete and return the proxy form we have sent to you.

Alternatively you can vote using our CREST proxy voting service following the procedures set out in the CREST Manual. You will still be able to vote on the day of the AGM 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.

Although we are respectfully asking shareholders not to attend the AGM in light of the Covid-19 pandemic, please complete and return the proxy form we have sent to you. The Company's Registrar, Equiniti, must receive the completed proxy form, at the address on the form, by no later than 2.00 pm on Tuesday 2 November 2021. Alternatively, you can vote using our CREST proxy voting service following the procedures set out in the CREST Manual.

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 of the shareholders as a whole. Accordingly, they recommend you vote in favour of each resolution as they intend to do in respect of their own beneficial shareholdings in the Company, which amount in aggregate to 480,424 shares representing approximately 0.16% of the existing ordinary share capital of the Company (excluding treasury shares).

Yours faithfully

Chris Stone Chair

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

Resolutions 1 to 14 (inclusive) and resolution 19 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 15 to 18 (inclusive) will be proposed as special resolutions. This means that, for each of those resolutions to be passed, not less than 75% of the votes cast must be in favour of the resolution.

Resolution 1: Receiving the Annual Report and Accounts

The Directors will present to the shareholders at the AGM the accounts for the year ended 31 May 2021, together with the Strategic Report and the reports of the Directors and the auditor.

Resolution 2: Approving the Directors' Remuneration Report (other than the Directors' remuneration policy)

The Directors' Remuneration Report is included in full on pages 100 to 118 of the Company's 2021 Annual Report and Accounts (the '2021 Annual Report') and provides details of the remuneration paid to the Directors in respect of the year ended 31 May 2021. For the purposes of this resolution, this does not include the parts of the Directors' Remuneration Report containing the Directors' remuneration policy, which is set out on pages 103 to 108.

In accordance with the Companies Act 2006 (the 'Companies Act'), this resolution to approve the Directors' Remuneration Report (other than the Directors' remuneration policy) is advisory only and therefore no entitlement to remuneration is conditional on it.

Resolution 3: Approving the Directors' remuneration policy

In accordance with the Companies Act 2006, the Company proposes an ordinary resolution to approve the Directors' remuneration policy contained in the Directors' Remuneration Report. The proposed policy is set out on pages 103 to 108 of the 2021 Annual Report. The vote on this resolution is binding and, if passed, will mean that remuneration payments and payments for loss of office can only be made to Directors or former Directors in accordance with the approved Directors' remuneration policy. The Company is required to ensure that a vote on its remuneration policy takes place at least every three years, unless it is proposed that the policy is to be changed before the expiry of the three year period, in which case the Company will propose a new resolution to approve the amended policy. The previous vote on the Company's existing Directors' remuneration policy was held in October 2020 and the policy is due to expire at the 2023 AGM.

Subject to approval at the AGM, the proposed Directors' remuneration policy will take effect from the end of the AGM and will replace the existing policy as approved by shareholders in 2020.

Resolution 4: 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 year ended 31 May 2021. If shareholders approve the recommended dividend, it will be paid on 12 November 2021 to shareholders on the register at close of business on 15 October 2021.

Resolutions 5 and 6: Appointment 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. An assessment of the effectiveness, independence and objectivity of the auditor has been undertaken by the Audit Committee, which has recommended to the Board that KPMG LLP be reappointed as auditor. 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. Accordingly, shareholder approval is being sought pursuant to resolution 5 to reappoint KPMG LLP as auditor of the Company.

Resolution 6 proposes that the Audit Committee be authorised to determine the level of the auditor's remuneration.

Resolutions 7–13: Re-election of Directors

Under the Company's Articles of Association (the 'Articles'), Directors appointed by the Board are required to submit themselves for election at the first AGM following their appointment. There have been no Directors appointed to the Board since the 2018 AGM; therefore, in accordance with the UK Corporate Governance Code every Director will stand for re-election at the AGM.

Biographical details of each Director standing for re-election can be found on pages 74 and 75 of the 2021 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 as set out in the 2021 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. 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 14: Granting the Directors authority to allot shares

Generally, the Directors may only allot shares in the Company (or grant rights to subscribe for, or to convert any security into, shares in the Company) if they have been authorised to do so by shareholders.

Resolution 14 renews a similar authority given at last year's AGM and is in two parts.

In line with guidance issued by the Investment Association, if passed, paragraph 14(a) of resolution 14 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 £1,029,910 (representing 102,991,000 ordinary shares). This amount represents approximately one-third of the issued ordinary share capital of the Company as at 10 September 2021 (being the latest practicable date before the publication of this document).

In addition, if passed, paragraph 14(b) of resolution 14 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 £1,029,910 (representing 102,991,000 ordinary shares). This amount represents approximately one-third of the issued ordinary share capital of the Company as at 10 September 2021 (being the latest practicable date before the publication of this document).

If given, these authorities will expire at the conclusion of the Company's next AGM. It is the Directors' intention to renew the allotment authority each year.

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 permitted by institutional shareholder guidelines to allot shares 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.

Resolutions 15 and 16: 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 2006) for cash, then under the Companies Act 2006 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.

Resolutions 15 and 16, which will be proposed as special resolutions, will enable the Directors to allot equity securities for cash or sell treasury shares for cash without first offering them to shareholders pro rata to their existing holdings. The resolutions take a similar form to the resolutions passed at last year's AGM.

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

• (a) in connection with a rights issue, open offer or other pre-emptive offer 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; and
• (b) in any other case, up to an aggregate nominal amount of £154,486 (representing 15,448,600 ordinary shares). This amount represents approximately 5% of the issued ordinary share capital of the Company as at 10 September 2021 (being the latest practicable date before the publication of this document).

This resolution renews the authority obtained at last year's AGM. If given, the authority granted under resolution 15 will expire on the conclusion of the AGM of the Company to be held in 2022.

The powers proposed under resolution 16 will be limited to allotments or sales of ordinary shares:

• (a) up to an aggregate nominal amount of £154,486 (representing 15,448,600 ordinary shares). This amount represents approximately 5% of the issued ordinary share capital of the Company as at 10 September 2021 (being the latest practicable date before the publication of this document); and
• (b) may be used only for the purposes of financing (or refinancing, if such refinancing occurs within six 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 on Disapplying Pre-Emption Rights most recently published by the Pre-Emption Group prior to the date of this Notice.

This resolution renews the authority obtained at last year's AGM. If given, the authority granted under resolution 16 will expire on the conclusion of the AGM of the Company to be held in 2022.

In accordance with the Pre-Emption Group's Statement of Principles, the Directors confirm that they do not intend to issue more than 7.5% of the issued ordinary share capital of the Company on a non-pre-emptive basis (except in connection with an acquisition or specified capital investment as referred to above) in any rolling three year period without prior consultation with shareholders. As noted in relation to resolution 14 above, the Directors have no current intention of issuing ordinary shares other than in relation to the Company's employee share schemes.

Resolution 17: 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 17, which will be proposed as a special resolution, renews a similar authority given at last year's AGM. The Directors presently have no intention of exercising the authority sought under resolution 17, but consider the authority desirable to provide maximum flexibility in the management of the Company's capital base. If passed, and in considering whether to use this authority, the Directors will take into account factors including the financial resources of the Company, the Company's share price and future funding opportunities. The Directors would only use this authority if they believed that to do so 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 2006. While held in treasury, the shares are not entitled to receive any dividend or dividend equivalent (apart from any issue of bonus shares) and 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.

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

continued

Resolution 17: Authority to purchase own shares continued

This resolution would be limited to 30,897,300 ordinary shares, representing approximately 10% of the issued equity share capital of the Company as at 10 September 2021 (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 conclusion of the Company's 2022 AGM. 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 September 2021 (being the latest practicable date prior to publication of this document) was 8,855,175, which represents approximately 2.87% of the Company's issued share capital and would represent 3.18% of the Company's issued share capital if the full authority to repurchase ordinary shares as proposed by resolution 17 was exercised.

As at 10 September 2021 (being the latest practicable date prior to publication of this document), the Company holds no shares in treasury.

Resolution 18: Notice of general meetings

Resolution 18 enables the Company to hold general meetings (other than AGMs) on 14 clear days' notice. The Articles currently permit such notice period, but this resolution is required in order to comply with the Shareholders' Rights Regulations.

The Company intends only to use the shorter notice period where the flexibility would be helpful given the business of the meeting and where the Company considers it is to the advantage of the shareholders as a whole. In accordance with the Companies Act 2006, 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.

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

Resolution 19: Political donations

Resolution 19 deals with political donations. Under the Companies Act 2006, 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 the legislation is capable of wide interpretation. 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.

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 19. This 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. As permitted under the Companies Act 2006, resolution 19 also covers any political donations made, or political expenditure incurred, by any subsidiaries of the Company. This authority will expire at the end of the next AGM of the Company.

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 return of the Proxy Form will not prevent you from attending and voting at the AGM if you so wish.

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 September 2021 were 308,973,042.
• 1. To be valid, the completed Proxy Form must be received by the Company's Registrar, Equiniti, by no later than 2.00 pm on Tuesday 2 November 2021 and should be addressed to Freepost RTHJ-CLLL-KBKU, Equiniti, Aspect House, Spencer Road, Lancing BN99 8LU.

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 2.00 pm on Tuesday 2 November 2021. 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 his 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.
