6 November 2025 By Order of The Board

Registered Office: Units 7 & 8

Fulcrum 4 Solent Way Whiteley Fareham Hampshire PO15 7FT

Teodora Angelova Andreeva

Chief Financial Officer

The notes on the following pages give an explanation of the proposed resolutions. Resolutions 1 to 11 are proposed as ordinary resolutions. This means that for each of those resolutions to be passed, more than half of the votes cast must be in favour of the resolution. Resolutions 12 and 13 are proposed as special resolutions. This means that for those resolutions to be passed, at least three-quarters of the votes cast must be in favour of the resolutions.

The directors must lay the Company's accounts, the directors' report and the auditor's report before the shareholders in a general meeting. A copy of those accounts and reports are enclosed with this document and are also available on the Company's website at https://www.cssgplc.com/investors/.

The Company is required to appoint an auditor at each general meeting at which accounts are laid before the shareholders, to hold office until the end of the next such meeting. Resolution 2 proposes the re-appointment of UHY Hacker Young LLP as the Company's auditor. Resolution 3 seeks authority for the directors to decide the auditor's remuneration.

Under Article 118 and subject to the provisions of the Companies Act, the Company may by ordinary resolution declare dividends in accordance with the respective rights of the members, but no dividend shall exceed the amount recommended by the Board. The Board has recommended a final dividend of

2.4p per ordinary share in issue being the total dividend for the financial year ended 30 June 2025.

Roberto Michele Fiorentino is currently the Chief Executive Officer and a member of the Board of Directors and has been nominated for re-appointment as a director. For the purposes of article 76.2 of the Company's Articles of Association his re-appointment is not required but is for completeness only. He will hold office from the date of his re-appointment until the 2026 annual general meeting of shareholders where he may retire from office and offer himself for re-appointment, or until his earlier death, resignation or removal. Mr. Fiorentino has agreed to serve if re-appointed, and the Board has no reason to believe that he will be unable to serve.

Teodora Angelova Andreeva is currently the Chief Financial Officer and a member of the Board of Directors and has been nominated for re-appointment as a director. For the purposes of article 76.1 of the Company's Articles of Association her re-appointment is required. If re-appointed she will hold office from the date of her re-appointment until the 2026 annual general meeting of shareholders where she will retire from office and offer herself for re-appointment, or until her earlier death, resignation or removal. Teodora Angelova Andreeva has agreed to serve if re-appointed, and the Board has no reason to believe that she will be unable to serve.

Stephen Naylor is currently a non-executive member of the Board of Directors and is not seeking re-election. For the purposes of article 76.1 of the Company's Articles of Association he will retire from office at the annual general meeting, unless his earlier death, resignation or removal. The resignation shall not result in a vacancy on the board and no appointment shall be made to fill the position vacated.

Under Article 76 of the Company's articles of association, at each Annual General Meeting of the Company any director who has been appointed by the Board since the previous annual general meeting is required to retire from office and may offer himself for re-appointment. Accordingly, John Nigel Wakefield has resolved to retire voluntarily and to submit himself for election by the shareholders.

Under Article 76 of the Company's articles of association, at each Annual General Meeting of the Company any director who has been appointed by the Board since the previous annual general meeting is required to retire from office and may offer himself for re-appointment. Accordingly, Andrew Robert Wonnacott has resolved to retire voluntarily and to submit himself for election by the shareholders.

The purpose of Resolution 10 is to confer upon the directors the power to allot shares. Section 551 of the Companies Act 2006 provides that the directors may not allot new shares (other than pursuant to employee share schemes) without shareholder approval.

The Resolution proposes that a new authority be granted in substitution for any existing authority to allot securities up to a maximum amount of £229,471, representing approximately 33.33 per cent. of the Company's current issued Ordinary Share capital. In addition (and as was the case at last year's annual general meeting), following guidance issued by The Investment Association, the Company is seeking additional authority to allot securities in connection with a fully pre-emptive rights issue up to a maximum amount of £458,942, representing approximately 66.66 per cent. of the Company's current issued Ordinary Share capital, as reduced by the nominal amount of any equity securities issued under paragraph (A) of Resolution 10. The benefit to the Company of obtaining such authority on an annual basis is that it would allow the Company to implement a rights issue of an amount equal to two thirds of the issued Ordinary Share capital without the need to call an additional general meeting. This would shorten the implementation timetable of such a rights issue. Shares held in treasury are ignored for the purposes of calculating the percentages and associated amounts referred to in Resolution 10 and in this note.

The directors have no present intention of exercising this authority. The authority conferred by Resolution 10 will expire at the conclusion of the next annual general meeting or, if earlier, on 31 December 2026, unless previously cancelled or varied by the Company in general meeting. It is the intention of the directors to renew this authority annually at each annual general meeting.

The purpose of resolution 11 is to allow the directors authority to transfer shares from treasury up to a maximum number of 200,000 ordinary shares. These shares may be freely transferred when an employee benefit trust is established for the purposes of establishing an employee share scheme of the Company.

Section 561(1) of the Companies Act 2006 provides that if the directors wish to allot any equity securities or sell any treasury shares (if it holds any), for cash, the Company must first offer them to existing shareholders in proportion to their existing shareholdings. Section 561 does not apply in connection with allotments made pursuant to an employee share scheme.

The purpose of Resolution 12 is to allow the directors to allot shares for cash as if section 561(1) of the Companies Act 2006 did not apply, in connection with rights issues, open offers and other pre-emptive offers pursuant to the authority to allot shares granted by Resolution 10, and otherwise up to a total amount of £68,841, representing approximately 10 per cent. of the Company's current issued Ordinary Share capital. The Resolution proposes that a new authority be granted in substitution for any existing authority.

Shares held in treasury are ignored for the purposes of calculating the percentages and associated amounts referred to in Resolution 12 and in this note.

The power conferred by Resolution 12 will expire at the conclusion of the next annual general meeting or, if earlier, on 31 December 2026, unless previously cancelled or varied by the Company in general meeting. It is the intention of the directors to renew this power annually at each annual general meeting.

Under Article 13 of the Company's Articles of Association, the Company may, from time to time, purchase its own shares subject to the terms of the Articles of Association and applicable statutory requirements. Resolution 13 is intended to grant the Directors authority to make market purchases of the Company's own ordinary shares of 5p each up to a maximum of 1,376,826 ordinary shares, being an amount equal to approximately 10 per cent. of the Company's current issued share capital. The maximum price payable is an amount equal to 105 per cent. of the average of the middle market quotations for an ordinary share of the Company for the five business days immediately preceding the date of purchase and the minimum price is the nominal value of 5p per share.

Shares held in treasury are ignored for the purposes of calculating the percentages and associated amounts referred to in Resolution 13 and in this note.

Although the Directors have no current intention to make such purchases, they consider that it is in the best interests of the Company and its members to have the ability to make market purchases of the Company's own shares in appropriate circumstances without the cost and delay of holding a general meeting. The authority would only be exercised if the Directors believed that the purchase would enhance earnings per share and be in the best interests of shareholders generally.

The Company may hold in treasury any of its own shares that it purchases in accordance with the authority conferred by Resolution 13. As at the date of publication of this document, the Company held 2,130,401 shares in treasury.

The power conferred by Resolution 13 will expire at the conclusion of the next annual general meeting or, if earlier, on 31 December 2026, unless previously cancelled or varied by the Company in general meeting. It is the intention of the directors to renew this power annually at each annual general meeting.

Any shareholder who is entitled to attend and vote at the AGM is entitled to appoint one or more proxies (who need not be shareholders) to attend the AGM and speak and vote instead of the shareholder. If more than one proxy is appointed each proxy must be appointed to exercise rights attached to different shares. Appointment of a proxy will not preclude a shareholder from attending and voting in person at the AGM.

In order for a proxy form to be valid, it must be completed and signed and returned to the Company's registrars, Neville Registrars Limited, at Neville House, Steelpark Road, Halesowen, B62 8HD so they receive it no later than 10 a.m. on 27 November 2025.

A shareholder wishing to appoint multiple proxies should contact the Shareholder Helpline on 0121 585 1131 to obtain additional proxy forms. Alternatively, you may wish to photocopy your proxy form. It will be necessary for the shareholder to indicate on each separate proxy form the number of shares in relation to which each such proxy is authorised to act.

Any corporation which is a shareholder can appoint one or more corporate representatives who may exercise on its behalf all of its powers as a shareholder provided that they do not do so in relation to the same shares.

To be entitled to attend and vote at the meeting (and for the purpose of the determination by the Company of the votes they may cast), shareholders must be registered in the register of members of the Company at 6 p.m. on 27 November 2025 or, in the event of any adjournment, on the date which is two days before the time of the adjourned meeting). Changes to the register of members after the relevant deadline shall be disregarded in determining the rights of any person to attend and vote at the meeting.

Copies of the following documents may be inspected at the registered office of the Company during normal business hours Monday to Friday (public holidays excepted) up to and including the day of the AGM, and at the venue for the AGM from half an hour before the time fixed for the AGM until the end of the AGM:

• the Company's annual report and accounts for the year ended 30 June 2025; and

• copies of the directors' service contracts.

Shareholders who have general queries about the AGM or need additional proxy forms should call the Shareholder Helpline on 0121 585 1131 (no other methods of communication will be accepted).

As at 6 November 2025 (being the latest practical date prior to publication of this notice) the Company's issued share capital consisted of 15,898,656 Ordinary Shares of which 2,130,401 are held in treasury. Therefore, total voting rights in the Company as at 6 November 2025 are 13,768,255.

Shareholders may not use any electronic address provided in either this notice of AGM or any related documents (including the chairman's letter and proxy form), to communicate with the Company for any purposes other than those expressly stated.
