Notice of Annual General Meeting

This document, which contains the notice of the annual general meeting of Babcock International Group PLC (the "Company"), is important and requires your immediate attention. If you are in any doubt about the action to take, please consult an independent financial adviser, who is authorised under the Financial Services and Markets Act 2000 if you are resident in the United Kingdom, or if not, from another appropriately authorised independent financial adviser.

Dear Shareholder

I am pleased to announce that the Company will hold its Annual General Meeting (the "AGM") at Ashurst LLP, Fruit & Wool Exchange, 1 Duval Square, London E1 6PW on Thursday, 25 September 2025 at 11.00am. The AGM is an important event in our corporate calendar as it provides the Board of Directors with an opportunity to present a review of the Company's performance, update shareholders on the Group's strategic priorities and listen to and respond to shareholder questions.

We set out the proposed resolutions, together with explanatory notes, on pages 2 to 5. Resolutions 19 to 21 will be proposed as special resolutions. All the rest will be proposed as ordinary resolutions. In line with our customary practice, we will hold the vote by a poll rather than on a show of hands, which ensures that we count the votes of shareholders who are not attending in person. Speaking on behalf of the Board of Directors, we encourage shareholders to submit any questions they would like to have answered at the AGM in advance, as this will enable us to respond to as many questions as possible at the AGM. You can do this by email to groupsecretariat@babcockinternational.com. If you attend the AGM, you may also submit questions during the meeting.

Voting

You can vote by proxy by visiting www.babcock-shares.com and following the instructions on that website. You will need to log in to your Babcock share portal or register, if you have not previously done so. To register, you will need your Investor Code, which is on your share certificate or dividend confirmation. Alternatively, to receive a paper form, please contact our Registrar, MUFG Corporate Markets, using the contact details set out in the Important Information for Shareholders on page 7. Our Registrar must receive your vote by 11.00am on Tuesday, 23 September 2025 or, in the event the AGM is adjourned, not less than 48 hours (excluding nonworking days) before the time fixed for the adjourned meeting. Further information on how to appoint a proxy is set out on pages 6 and 7.

Voting by proxy prior to the AGM does not affect your right to attend the AGM and vote in person should you so wish.

Recommendation

Your Directors believe that all of the proposed resolutions are in the best interests of the Company and its shareholders as a whole and unanimously recommend that you vote in favour of all of them, as your Directors intend to do in respect of their own beneficial holdings.

Yours sincerely

Dame Ruth Cairnie DBE

Chair 16 July 2025

such authorities to apply (unless previously renewed, varied or revoked by the Company in a general meeting) until the end of the Company's next annual general meeting (or, if earlier, until the close of business on 24 December 2026) but, in each case, so that the Company may make offers and enter into agreements before the authority expires which would, or might, require shares to be allotted or rights to subscribe for or to convert any security into shares to be granted after the authority expires and the Directors of the Company may allot shares or grant such rights under any such offer or agreement as if the authority conferred hereby had not expired. References in this Resolution 17 to the nominal amount of rights to subscribe for or to convert any security into shares (including where such rights are referred to as equity securities as defined in section 560(1) of the 2006 Act) are to the nominal amount of shares that may be allotted pursuant to the rights.

Explanatory Notes to the Resolutions

The shareholders will pass Ordinary Resolutions 1 to 18 if the votes cast for these Resolutions are more than those cast against. The shareholders will pass Special Resolutions 19 to 21 if the votes cast for these Resolutions are 75% or more in favour. The Board considers that all the Resolutions in the notice of the AGM are in the best interests of the Company and its shareholders as a whole. Your Directors unanimously recommend that you vote in favour of them as they intend to do in respect of their own beneficial holdings.

Resolution 1: Report and Accounts

The Directors must lay the Annual Report and Financial Statements before the shareholders at each annual general meeting.

Resolution 2: Directors' Remuneration Policy

Every year the Remuneration Committee reviews the Company's remuneration policy. This year following its review, the Committee decided to make certain changes to the policy, which it has fully described in Directors' Remuneration Policy on pages 156 to 162 of the Company's Annual Report and Financial Statements 2025. Before proposing the changes, the Committee engaged with certain of its largest shareholders to canvass their views. The Committee took these views into account before putting the changes to shareholders.

Resolution 3: Directors' Remuneration Report

We are asking shareholders to approve the Directors' remuneration report for the year ended 31 March 2025, which is set out on pages 163 to 177 of the Company's Annual Report and Financial Statements 2025. The vote upon this resolution is advisory. The vote is not specific to individual levels of remuneration and the Directors' entitlement to remuneration is not conditional on it.

Resolution 4: Final Dividend

Shareholder approval is sought for a final dividend for the year ended 31 March 2025 of 4.5p per ordinary share. If approved at the AGM, this would be paid on Tuesday, 30 September 2025 to those shareholders on the Company's register of members at close of business on Friday, 22 August 2025.

Resolutions 5 to 13: Reappointment of Directors

In line with article 80 of the Company's articles of association and the provisions of the UK Corporate Governance Code (the "Code"), all Directors will retire at the AGM and stand for re-appointment, as proposed in resolutions 5 to 13. The Directors named in Resolutions 5 to 10 and 12 and 13 were all reappointed at last year's annual general meeting.

Following the annual performance evaluation of all Directors, the Board is satisfied that the individual performance of each Director continues to be effective and demonstrates commitment to his or her role. Their biographical details, which are set out in Appendix 1 to this Notice, demonstrate how the Board has the appropriate balance of skills, experience, independence and knowledge to lead the Company's long-term sustainable success. Accordingly, the Board unanimously recommends their reappointment.

The Board has reviewed the independence of its Non-Executive Directors and has determined that each of them continues to be independent.

Resolutions 14 and 15: Appointment and remuneration of the auditor

On the recommendation of the Audit Committee, the Board is recommending to shareholders the reappointment of Forvis Mazars LLP as external auditor of the Company. If approved, Forvis Mazars LLP will be our external auditor for the year ending 31 March 2026.

In accordance with standard practice, Resolution 15 authorises the Audit Committee, on behalf of the Board, to determine the remuneration of the Company's auditor.

Resolution 16: Political donations and expenditure

We do not make political donations or incur political expenditure within the ordinary meaning of those terms. However, certain activities undertaken in the usual course of business may inadvertently fall within the legal definition of political donation or political expenditure. In line with standard practice, on an annual basis, we ask shareholders to approve on a precautionary basis a limited authority to ensure that the Company does not commit any technical breach of the 2006 Act.

Resolution 17: Authority to Allot

Under section 551 of the 2006 Act, the Directors may only allot shares or grant rights over shares if authorised to do so by shareholders. This Resolution seeks authority to allot (a) shares up to an aggregate nominal value of £101,119,319.40 (such amount to be reduced by any allotments or grants made under paragraph (b) in excess of such amount) and (b) equity securities up to an aggregate nominal amount of £202,238,638.80 (such amount to be reduced by any allotments or grants made under paragraph (a)) where the allotment is in connection with a fully pre-emptive offer (including a rights issue or open offer). These amounts represent a maximum of 33.3% and 66.6% respectively of the total issued ordinary share capital of the Company as at 9 July 2025*.

This resolution is in accordance with the guidance provided by the Investment Association on the Directors' authority to allot. This guidance permits resolutions seeking authority to allot shares representing up to two-thirds of the Company's issued share capital if Directors use such authority (that part provided by paragraph (b) of Resolution 17) to allot shares pursuant to a fully pre-emptive offer, including a rights issue or open offer. If granted, this authority will expire at the end of the Company's annual general meeting in 2026 (or, if earlier, the close of business on 24 December 2026). As at 9 July 2025* the Company held no treasury shares.

The Directors have no present intention of exercising the allotment authority sought under Resolution 17 unless required for the allotment of ordinary shares in respect of options and awards under employee share plans. However, the Directors consider it desirable to have the flexibility to use it should opportunities arise. If the Directors do exercise the authority, the Directors intend to follow market best practice as regards its use.

Resolution 18: Amendments to the Babcock International Group PLC Performance Share Plan 2019 (PSP)

The resolution seeks Shareholder approval to amend the PSP to implement the changes to the PSP needed to implement amendments to the Company's remuneration policy which the Company is proposing under resolution 2.

The PSP is the Company's long term incentive plan, under which annual performance-based share plan grants are made to the Company's Executive Directors and the broader leadership team. The PSP currently provides that the maximum grant level in respect of any financial year must not exceed 200% of annual base salary or (for executive directors only) any other limit approved by shareholders in the Company's remuneration policy from time to time.

Under resolution 2, the Company is proposing changes to its remuneration policy including the introduction of a "TSR kicker" for the PSP. Under the kicker, the maximum award received by the CEO could be 500% if the TSR performance conditions are met. Therefore, it is proposed that the maximum grant level under the PSP be increased to 500% of annual base salary (or any other limit approved in the future by Shareholders as part of any change to the remuneration policy) to align with the changes to the remuneration policy.

Additionally, to provide greater flexibility, an amendment is proposed to specify that grants may be made under the PSP in the 6 weeks after any amendment to the plan approved by shareholders. No other amendments are proposed to the PSP other than typographical updates. A copy of the rules of the PSP (showing the proposed amendments) is available for inspection at the National Storage Mechanism and at the place of the meeting from at least 15 minutes before the General Meeting until the end of the General Meeting.

Resolution 19: Disapplication of Pre-emption rights

Under section 561(1) of the 2006 Act, the Company cannot issue ordinary shares for cash until it has first offered them pro rata to existing shareholders.

We are asking shareholders for authority to allot a limited number of shares or equity securities or sell treasury shares otherwise than to existing shareholders pro rata to their holdings. Apart from offers or invitations in proportion to the respective number of shares held, the authority in Resolution 19 will be limited to:

• (a) pre-emptive offers, including rights issues or open offers, and offers to holders of other equity securities if required by the rights of those securities, or as the Board otherwise considers necessary;
• (b) the issue of shares and sales of treasury shares for cash up to a maximum aggregate nominal value of £30,335,795 (representing approximately 10% of the Company's issued ordinary share capital as at 9 July 2025*); and
• (c) allotments or sales up to an additional aggregate nominal amount equal to 20% of any allotments or sales made under (b) above (so a maximum of 2%), such power to be used only for the purposes of making a follow-on offer of a kind contemplated by Section 2B of the Pre-Emption Group's Statement of Principles.

If granted, this authority will expire at the conclusion of the annual general meeting of the Company to be held in 2026, (or, if earlier, the close of business on 24 December 2026). The limits in Resolution 19 are in line with those set out in the Pre-Emption Group's Statement of Principles published in November 2022.

The Directors have no present intention to exercise the powers sought by Resolution 19. If the powers sought by Resolution 19 are used in relation to a non-pre-emptive offer, the Directors confirm their intention to follow the shareholder protections in paragraph 1 of Part 2B of the Pre-Emption Group's Statement of Principles and, where relevant, follow the expected features of a follow-on offer as set out in paragraph 3 of Part 2B of the Pre-Emption Group's Statement of Principles.

Resolution 20: Authority to Purchase Own Shares

If passed, Resolution 20 will renew the general authority for the Company to make market purchases of its own ordinary shares as permitted by the 2006 Act. Many other listed companies have this authority. This resolution specifies the maximum number of shares which the Company may acquire (a maximum of 10% of the Company's issued share capital as at 9 July 2025*) as well as minimum and maximum prices. If granted, the authority would expire at the conclusion of the annual general meeting of the Company to be held in 2026 (or, if earlier, the close of business on 24 December 2026). The Company would either cancel or hold as treasury shares any shares purchased under this authority. Any shares held in treasury could subsequently be cancelled, sold for cash or transferred under the Company's employee share plans (including under the Company's all-employee share purchase and free share plans).

As at 9 July 2025*, the total number of ordinary shares that may be issued on the exercise or vesting of outstanding options or awards under the Company's executive or employee share schemes represented approximately 2.4% of the Company's issued share capital as at that date. If the authority given by this Resolution 20 was exercised in full and those shares were subsequently cancelled, these options or awards would represent 2.7% of the Company's issued ordinary share capital.

The Directors have no present intention of using this authority other than in connection with the £200 million share buyback programme that the Company announced on 25 June 2025 it intends to launch over the next 12 months. The Directors would only exercise the authority if it is in the best interests of the Company and its shareholders generally to do so and (except in the case of a purchase of own shares to fulfil obligations under the Company's executive or employee share schemes) any purchase could reasonably be expected to result in an increase in earnings per share of the Company (taking into account the relevant factors and circumstances at the time).

Resolution 21: Notice for General Meetings

Authority is sought from shareholders to allow general meetings (other than annual general meetings) to be called on 14 clear days' notice rather than the 21 days otherwise required by section 307A of the 2006 Act. The Company would like to preserve the authority given at last year's annual general meeting. The Company would not use the shorter notice period as a matter of routine for general meetings, but only where the business of the meeting merits the flexibility and is to the advantage of shareholders as a whole.

* 9 July 2025 being the latest practicable date prior to the publication of this notice.

CREST Personal Members or other CREST-sponsored members, as well as those CREST members, who have appointed a voting service provider(s), should refer to their CREST sponsor or voting service provider(s), who will take the appropriate action on their behalf.
• 1. 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 Euroclear UK & International Limited's specifications, and must contain the information required for such instruction, as described in the CREST Manual (available via www.euroclear.com). 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 received by the issuer's agent (ID RA10) by 11.00am on Tuesday, 23 September 2025 (or not less than 48 hours before the time fixed for any adjourned AGM, provided that no account shall be taken of any part of a day that is not a working day).

Before proxies can be appointed via this process, institutional investors will need to have agreed to Proxymity's associated terms and conditions. It is important that these are read carefully as investors will be bound by them and they will govern the electronic appointment of proxies. An electronic proxy appointment via the Proxymity platform may be revoked completely by sending an authenticated message via the platform instructing the removal of your proxy vote.
