21 April 2026 Dear Shareholder

Annual General Meeting

This document sets out details of the Company's Annual General Meeting (AGM) which is to be held at 17 Waterloo Place, London, SW1Y 4AR at 09:00 on 20 May 2026. The formal Notice of Annual General Meeting is set out after this letter and summary details of the Resolutions to be proposed at the AGM are included below.

The audited Annual Report and Financial Statements for the year ended 31 December 2025 are available on the Company's website https://www.sciencegroup.com and provide consolidated financial information for the Company together with the Statement of the Executive Chair and other reports describing recent progress made by the Company.

The Board recommends that shareholders submit their vote in advance and appoint the Chair of the AGM as their proxy. Please register your proxy appointment electronically via https://www.shareview.co.uk or, if you are a CREST member, through the CREST proxy appointment service. If you are an institutional investor, you may also be able to appoint a proxy electronically via the Proxymity platform. Alternatively any shareholder may complete and return a hard copy Form of Proxy. Instructions for all options are included in the notes to this document.

The deadline for receipt by our Registrar of all proxy appointments is 09:00 on 18 May 2026. The appointment of a proxy does not prevent you from attending the AGM and voting in person.

All voting at the AGM will be on a poll in accordance with recommended best practice. The results of voting on all the Resolutions will be announced via the Regulatory News Service and published on the Company's website as soon as practicable after the end of the AGM.

Resolutions to be proposed at the AGM are as follows:

UK company law requires the Directors to present their Annual Report and Financial Statements for each year for formal adoption by shareholders. The Annual Report and Financial Statements of the Company for the year ended 31 December 2025 are available to shareholders on the Company's website https://www.sciencegroup.com.

The Company is required to appoint auditors at each AGM at which the accounts are laid before the Company, to hold office until the conclusion of the next such meeting. Grant Thornton UK LLP has been appointed by the Board as external auditors of the Company annually since 2020.

The Audit Committee has reviewed the independence, effectiveness and objectivity of Grant Thornton UK LLP, on behalf of the Board, who now propose their reappointment as auditors of the Company.

2

This Resolution authorises the Directors, in accordance with standard practice, to negotiate and agree the remuneration of the auditors.

The articles of association of the Company require that every Director that has been appointed by the Board since the last AGM or who was not appointed or reappointed at one of the two preceding AGMs must retire from office at the AGM and may offer themselves for re-election.

Therefore Martyn Ratcliffe and Susan Clement Davies are retiring and standing for re-election at the AGM. Martyn Ratcliffe is the Executive Chair and Susan Clement Davies is a Non-Executive Director of the Company. The Board has reviewed the performance of Mr Ratcliffe and Ms Clement Davies and considers that they continue to make effective and valuable contributions to the Board and demonstrate commitment to the role.

Brief biographies of the Directors are available on the Company's website https://www.sciencegroup.com and described in the Annual Report and Financial Statements for the year ended 31 December 2025.

A final dividend can only be paid after the shareholders at a general meeting have approved it. A final dividend of 10.0 pence per ordinary share is recommended by the Directors for payment to shareholders who are on the register at the close of business on 22 May 2026.

Resolution 7 gives the Directors authority to allot ordinary shares up to an aggregate nominal amount of £137,380.34 being an amount equal to approximately one third of the Company's issued share capital (excluding treasury shares) as at 17 April 2026 (being the latest practicable date prior to the publication of this document).

The authorities granted under this Resolution will expire at the conclusion of the next AGM or, if earlier, 30 June 2027. This authority would replace an existing similar authority granted at the annual general meeting held 21 May 2025.

If the Directors wish to allot shares or other equity securities for cash, the Companies Act 2006 requires that such shares or other equity securities are offered first to existing shareholders in proportion to their existing shareholding. Resolutions 8 and 9 give the Directors authority to allot shares and/or sell treasury shares for cash without having to offer them first to existing shareholders.

The authorities granted under these Resolutions comply with the Pre-Emption Group's revised Statement of Principles on Disapplying Pre-Emption Rights and are being sought to allow maximum flexibility. However, they will only be exercised if the Directors consider it to be in the best interests of the Company at the time and should not be taken as an indication of the Directors' intentions.

Resolution 8 asks shareholders to grant the Directors authority to do the following without first offering the securities to existing shareholders:

1. allot equity securities up to an aggregate nominal value of £41,214.10 (being approximately 10 per cent. of the Company's issued ordinary share capital (excluding treasury shares) as at 17 April 2026); and

2. sell treasury shares for cash up to an aggregate nominal value equal to the nominal value of the treasury shares held by the Company at the date of any such sales.

The authority granted under Resolution 8 will replace an existing similar authority granted at the annual general meeting held on 21 May 2025.

Resolution 9 asks shareholders to grant the Directors authority to allot equity securities up to an additional aggregate nominal value of £41,214.10 (being approximately 10 per cent. of the Company's issued ordinary share capital (excluding treasury shares) as at 17 April 2026) without first offering the securities to existing shareholders where the allotment is in connection with an acquisition or specified capital investment (within the meaning of the Statement of Principles).

These authorities will expire at the conclusion of the next AGM or, if earlier, 30 June 2027.

3

Resolutions 10 and 11 give the Company authority to purchase its own issued share capital.

Under Resolution 10 the Company is seeking its standard authority to purchase up to 4,121,410 ordinary shares representing approximately 10 per cent. of the Company's issued ordinary share capital (excluding treasury shares) as at 17 April 2026 (being the latest practicable date prior to the publication of this document) at, or between, the minimum and maximum prices specified in this Resolution.

Under the buyback authority granted at the 2025 AGM, the Company has purchased 3,724,088 shares as at 17 April 2026 (being the latest practicable date prior to the publication of this document), being approximately

83.5 per cent. of the authority granted.

The Company acknowledges the substantial cash balances held by the Company, reinforced by the consistent operating cash flow from the business. While dialogue with major shareholders encourages the Company to seek to deploy the capital to accelerate the growth of the Group, the Company remains concerned that its relative valuation may act as an inhibitor. Indeed, the Directors consider that, on a relative valuation basis, one of the most attractive buying opportunities is the repurchase of the Company's shares. Accordingly, additional capital allocation to the buy-back programme may be appropriate if the Directors consider it to be in the best interests of the Company's shareholders and this could potentially exceed the standard buyback authority granted under Resolution 10. To facilitate this option in a timely and cost-effective manner, the Directors consider it to be in the interests of shareholders to seek an additional buyback authority to permit further purchases of the Company's shares should this be deemed appropriate in the future.

Therefore, under Resolution 11, the Company is seeking authority to purchase up to an additional 4,121,410 ordinary shares representing approximately a further 10 per cent. of the Company's issued ordinary share capital (excluding treasury shares) as at 17 April 2026 (being the latest practicable date prior to the publication of this document) at, or between, the minimum and maximum prices specified in this Resolution.

The Directors would use the authorities granted under Resolutions 10 and 11 only after careful consideration, having taken into account market conditions prevailing at that time, the investment needs of the Company, its opportunities for expansion and its overall financial position. The Directors would exercise these authorities to purchase ordinary shares only if they considered it to be in the best interests of shareholders and if the purchase could reasonably be expected to result in an increase in earnings per share.

Furthermore, the additional authority sought under Resolution 11 would be exercised by the Directors only after the authority sought under Resolution 10 has been exhausted and where the Board considers it to be in the best interests of shareholders to continue to purchase shares. For the avoidance of doubt, the Directors are not at the present time intending to use the authority sought under Resolution 11 and the Directors would notify shareholders of the intent to utilise this authority as appropriate.

Under the Companies Act 2006, the Company is allowed to hold its own shares in treasury following a buyback instead of cancelling them. Such shares may be resold for cash or used for the purpose of employee share schemes but all rights attaching to them, including voting rights and any right to receive dividends, are suspended whilst they are held in treasury. Accordingly, if the Directors exercise the authority conferred by Resolutions 10 and 11, the Company will have the option of holding these shares in treasury, rather than cancelling them.

The authorities sought at the AGM will expire at the conclusion of the next annual general meeting of the Company or, if earlier, 30 June 2027.

The Remuneration Committee of the Board undertook a review of the Enhanced Executive Incentive ("EEI") awards granted to senior management in 2021 under the EEI addendum to the Company's standard Performance Share Plan ("PSP"). The review found that, while the share price targets set were aligned with Company performance expectations and valuation multiples at the time of grant in 2021, broader market conditions and sector specific pressures have resulted in share price drag that does not, in the view of the Remuneration Committee, reflect the operational and financial progress achieved by the Company.

As part of the review, the Company consulted with its largest institutional shareholders, who indicated their support for the proposed approach.

In order to ensure that the total incentive package for senior management remains appropriately aligned with performance, retention and long-term value creation, the Board, on the recommendation of the Remuneration Committee, seeks shareholder approval to extend the vesting period from 14 October 2026 to 30 April 2028. Such an extension would be subject to orderly market provisions for a period of two years.

4

The Board considers that the Resolutions are fair and reasonable and in the best interests of shareholders as a whole.

Accordingly, the Board unanimously recommends that shareholders vote in favour of the Resolutions to be proposed at the AGM as they intend to do in respect of their own beneficial holdings in the Company which on 17 April 2026 (the latest practicable date prior to the publication of this document) amounted in aggregate to 8,152,080 ordinary shares, representing approximately 19.8 per cent. of the current issued ordinary share capital of Science Group (excluding treasury shares).

Changes to entries on the register after 18:30 on 18 May 2026 shall be disregarded in determining the right of any person to attend or vote at the AGM.

   VOTING

2. Shareholders have the following voting options:

   1. online by following by appointing a proxy electronically at https://www.shareview.co.uk (see note 10);

   5. attendance in person at the AGM.

3. A vote withheld option is provided to enable shareholders to instruct a proxy to abstain on any particular Resolution. However, it should be noted that a "vote withheld" is not a vote in law and will not be counted in the calculation of the proportion of the votes "For" and "Against" a Resolution.

   PROXIES

4. A shareholder entitled to attend and vote is entitled to appoint a proxy or proxies to attend, speak and vote instead of him/her. A shareholder may appoint more than one proxy provided that each proxy is appointed to exercise the rights attached to a different share or shares held by them. A proxy need not be a shareholder of the Company.

5. Shareholders are strongly encouraged to appoint the Chair of the AGM as proxy with voting instructions.

6. Appointing a proxy does not prevent a shareholder from attending and voting in person. If a shareholder has appointed a proxy and attends the meeting in person and vote, the proxy appointment will automatically be terminated.

7. Shareholders may change proxy instructions by submitting a new proxy appointment using the methods set out in these notes. The cut-off time for receipt of proxy appointments also applies in relation to amended instructions and any amended proxy appointment received after the relevant cut-off time will be disregarded. If a shareholder submits more than one valid proxy appointment, the appointment received last before the cut-off time for receipt of proxies will take precedence. Shareholders must inform the Company's registrars in writing of any termination of the authority of a proxy.

8. Hard copy Forms of Proxy can be requested from Equiniti Limited on +44 (0)371 384 2030 (please ensure the country code is used if calling from outside the UK). Calls are charged at the standard geographic rate and will vary by provider. Calls outside the UK will be charged at the applicable international rate. Lines are open weekdays between 08:30 and 17:30 excluding public holidays in England and Wales.

9. In order to be valid, a hard copy Form of Proxy together with the power of attorney or other authority (if any) under which it is signed, or a notarially certified copy of such power or authority, must be received by Equiniti Limited at Highdown House, Yeoman Way, Worthing, West Sussex BN99 6DA no later than 09:00 on 18 May 2026 (or, if the AGM is adjourned, not less than 48 hours before the time fixed for the adjourned meeting) (excluding non-working days).

   ONLINE VOTING INSTRUCTIONS

10. Shareholders are encouraged to vote online by following the instructions for the electronic appointment of a proxy at https://www.shareview.co.uk where details of the voting procedures are shown. If you have not already registered you will require your Shareholder Reference Number printed on the form of proxy. The appointment must be received by Equiniti Limited no later than 09:00 on 18 May 2026 (or, if the AGM is adjourned, not less than 48 hours before the time fixed for the adjourned meeting) (excluding non-working days).

    CREST VOTING INSTRUCTIONS

11. CREST members who wish to appoint a proxy by utilising the CREST electronic proxy appointment service may do so for the meeting and any adjournment(s) of it by using the procedures described in the CREST Manual (available via www. euroclear.com). 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.

12. For a proxy appointment or instructions made using the CREST service to be valid, the appropriate CREST message (a CREST Proxy Instruction) must be properly authenticated in accordance with Euroclear UK & International Limited's (EUI) specifications and must contain the information required for such instructions as described in the CREST Manual. The message, regardless of whether it constitutes the appointment of a proxy or is an amendment to the instruction given to a previously appointed proxy, must, in order to be valid, be transmitted so as to be received by the issuer's agent (ID number RA19) no later than 09:00 on 18 May 2026 (or, if the AGM is adjourned, not later than 48 hours before the time fixed for the adjourned meeting) (excluding non-working days). 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.

    9

13. CREST members and, where applicable, their CREST sponsors or voting service providers should note that EUI does not make available special procedures in CREST for any particular message. 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/her 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.

14. 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.

16. A person to whom this Notice of Annual General Meeting is sent who is a person nominated under Section 146 of the Companies Act 2006 to enjoy information rights (Nominated Person) may, under an agreement between themselves and the shareholder by whom they were nominated, have a right to be appointed (or to have someone else appointed) as a proxy for the AGM.

17. The statements of the rights of shareholders in relation to the appointment of proxies in these notes do not apply to a Nominated Person.
