Chair's letter

Dear Shareholder

Annual General Meeting 2024

I am writing to you regarding the 2024 Annual General Meeting (the 'AGM') of Morgan Sindall Group plc (the 'Company'), which will take place at 10.00am on Thursday, 2 May 2024 at the offices of Morgan Sindall Group plc, Kent House, 14-17 Market Place, London W1W 8AJ.

The AGM is an opportunity for you, as a shareholder, to express your views directly to the Board, either by attending the meeting in person or submitting a question on the business to be discussed at the AGM in advance of the meeting.

The notice convening the meeting (the 'Notice of Meeting') is set out on pages 2 to 4. A detailed explanation of the business to be considered at the meeting is set out on pages 5 to 7.

The directors believe that, in the interest of shareholder democracy, it is important that all members are given the opportunity to vote, regardless of whether they can attend the AGM. All resolutions will therefore be put to shareholders by way of a poll rather than a show of hands.

Action required

Whether or not you intend to be present at the AGM, you are strongly encouraged to appoint a proxy to cast your votes as soon as possible. All shareholders are sent either a proxy form or an email containing a Control Number, Shareholder Reference Number and PIN.

You can either complete, sign and return the proxy form, or submit an electronic proxy appointment instruction at www.investorcentre.co.uk/eproxy. In order for your vote to be counted, your instructions must be received by the Company's registrar at the relevant address set out in the Important notes to the Notice of Meeting, by no later than 10.00am on Tuesday, 30 April 2024.

Completion and return of the proxy form or submission of an electronic instruction will not preclude you from attending and voting in person at the AGM should you subsequently decide to do so.

Questions

It is important to us that we have the opportunity to hear from you, as a shareholder, directly. You will be able to ask questions of the Board either in person if you are able to attend the AGM, or by submitting questions in advance of the meeting by emailing [e-mail] (marked for the attention of the Company Secretary).

We will endeavour to publish (on an anonymised basis) any questions received before 10.00am on Tuesday,

30 April 2024, and our responses to those questions, on our website (www.morgansindall.com/investors/annual- general-meeting)prior to the AGM. Following the AGM, we will publish (on an anonymised basis) the full set of questions received (including those received after 10.00am on Tuesday, 30 April 2024 and at our AGM) and answers to those questions on our website (www.morgansindall. com/investors/annual-general-meeting). However, we reserve the right to edit questions or not to respond where we consider it appropriate to do so, taking account of our legal obligations.

Dividend payments

Shareholders are reminded that the Company no longer issues dividend payments by cheque and instead pays dividends directly into a nominated bank or building society account. You are therefore encouraged to ensure that your account details are recorded with the Company's Registrar as soon as possible, but no later than 26 April 2024, in order to have your dividend paid directly to you on the proposed 2024 final dividend payment date of 16 May 2024. Please see note 25 for further details and contact information.

Recommendation

The directors consider that all the resolutions to be proposed at the AGM are in the best interests of the Company and

its shareholders as a whole, and accordingly, unanimously recommend that you vote in favour of the resolutions, as they intend to do in respect of their own beneficial shareholdings.

The results will be published on the 'Annual General Meeting' page of our website at www.morgansindall.com and will be released as soon as reasonably practicable via a Regulatory Information Service following the conclusion of the AGM.

Yours faithfully

Michael Findlay

Chair

Explanatory notes to the resolutions

Chair's letterNotice of meeting Explanatory notes to the resolutions Important notes

The explanatory notes on the following pages explain each of the proposed resolutions. Resolutions 1 to 15 (inclusive) are proposed as ordinary resolutions. This means that for each of these resolutions to be passed, more than half of the votes cast must be in favour of the resolution. Resolutions 16 to 19 (inclusive) are proposed as special resolutions. For each of these resolutions to be passed, at least three quarters of the votes cast must be in favour of the resolution.

All resolutions at the AGM will be put to shareholders by way of a poll rather than a show of hands. A poll vote is more representative of shareholders' voting intentions because shareholder votes are counted according to the number of shares held and all votes tendered are counted. After the meeting, the results of voting, including proxy directions to withhold votes, will be published on our website.

Ordinary resolutions

Resolution 1: Annual Report

The directors of the Company are required to lay the annual report and accounts of the Company before the shareholders each year at the AGM. The Company's Annual Report for the year ended 31 December 2023 comprises the audited financial statements, the auditor's report, the directors' and corporate governance report, the strategic report and the remuneration report.

Resolution 2: Final dividend

The Board recommends the payment of a final dividend of 78 pence per ordinary share. Subject to approval by shareholders, the final dividend will be paid on 16 May 2024 to all ordinary shareholders on the register of members at close of business on 26 April 2024.

Resolution 3: Directors' remuneration report

In accordance with the Companies Act 2006 (the 'Act'), the Company is required to offer a binding vote on the Company's forward-looking directors' remuneration policy (the 'Policy') at least once every three years and a separate advisory vote on the implementation of the Company's existing remuneration policy (as set out in the directors' remuneration report) each year. The Policy, which is currently in force and set out on pages 143 to 152 of the Annual Report, was approved by shareholders at the AGM held in May 2023 and is therefore not itself the subject of a resolution at this year's AGM.

The remuneration report is set out on pages 135 to 162 of the Annual Report. It provides details of the directors' remuneration for the year ended 31 December 2023. The Board considers that appropriate executive remuneration encourages the effective stewardship that is vital to delivering our strategy of creating long-term value for all stakeholders. Accordingly, in compliance with applicable legislation, shareholders will be invited to approve the directors' remuneration report. The vote on this resolution is advisory only and the directors' entitlement to remuneration is not conditional on this resolution being passed.

Resolutions 4 to 11: Appointment and reappointment of directors

Under the Company's articles of association, at every AGM all the directors at the date of the notice convening the AGM shall retire from office and may offer themselves for reappointment by the members. Each of our directors will stand for re-election at this year's AGM except for Sharon Fennessy who will be standing for election, this being the first AGM since her appointment. The directors' biographies are set out on pages 104 and 105 of the Annual Report and include details of their skills, competencies and experience. The directors' balance of knowledge and skills, combined with their breadth of business experience, makes a significant contribution to the effective functioning of the Board and is, and continues to be, important to the Company's long-term sustainable success.

Following the annual evaluation process, the Board believes that the performance of each director proposed to be reappointed at the AGM continues to be effective and that they demonstrate commitment to their respective roles.

Resolutions 12 and 13: Reappointment and remuneration of the auditor

The Company is required to appoint an auditor at each general meeting at which accounts are laid to serve until the next such meeting. Ernst & Young LLP has indicated its willingness to continue in office and resolution 12 proposes its reappointment to hold office from the conclusion of this meeting until the conclusion of the next general meeting at which accounts are laid before the Company.

In accordance with normal practice, resolution 13 proposes that the auditor's remuneration be determined by the directors. The Board will delegate this authority to the audit committee to negotiate and agree the auditor's remuneration.

Resolution 14: Political donations

This resolution will renew the authority given at last year's AGM, which is due to expire at the 2024 AGM. Under sections 366 and 367 of the Act, the Company is required to seek shareholders' authority to make any political donations and/or incur political expenditure. Although the Company does not make, and does not intend to make, donations to political parties and/or to independent election candidates within the normal meaning of that expression, the legislation is very broadly drafted and may catch activities such as: funding seminars and other functions to which politicians are invited; supporting certain bodies involved in policy review and law reform; and matching employees' donations to certain charities.

Therefore, in accordance with current best practice, the directors have decided to propose an ordinary resolution to authorise the Company and its subsidiaries to make certain types of political donations and/or expenditure, as more particularly described in the resolution, up to an aggregate amount of £25,000. This authority shall expire at the conclusion of next year's AGM, or close of business on 2 August 2025, whichever is earlier.

Resolution 15: Directors' authority to allot shares

The directors currently have authority to allot shares in the Company and to grant rights to subscribe for or convert any securities into shares in the Company. This authority is due to lapse at our 2024 AGM. The Board is seeking by this ordinary resolution to renew the directors' authority to allot shares in the capital of the Company in accordance with section 551 of the Act.

Paragraph (a) of this resolution would give directors the authority to allot shares or grant rights to subscribe for or convert any securities into shares up to an aggregate nominal amount equal to £789,337.05 (representing 15,786,741 shares). This amount represents approximately one third of the total issued share capital of the Company as at 13 March 2024, the latest practicable date prior to the date of this Notice

of Meeting.

The directors have noted the latest Share Capital Management Guidelines published by The Investment Association (the 'IA') in February 2023, which updated the previous guidance to allow the authority in paragraph (b) of this resolution to incorporate all fully pre-emptive offers, not just fully pre-emptive rights issues. Similar to last year's AGM, the directors have decided that they will continue to propose limiting the relevant limb of the allotment authority to rights issues in line with past practice but will continue to keep emerging market practice under review. As a result, paragraph (b) of this resolution would give the directors the authority to allot shares or grant rights to subscribe for or convert any securities into shares in connection with a rights issue, up to an aggregate nominal amount equal to £1,578,674.15 (representing 31,573,483 shares), as reduced by the nominal amount of any shares issued under paragraph (a) of this resolution. This amount (before any reduction) represents approximately two thirds of the total issued share capital of the Company as at 13 March 2024, being the latest practicable date prior to the date of this Notice of Meeting.

The authorities sought under this resolution, if passed, will expire at the conclusion of the Company's next AGM or close of business on 2 August 2025, whichever is earlier. The directors currently have no intention of issuing further shares or granting rights over shares other than in connection with the Company's employee share option and share incentive schemes. However, if the directors do exercise the authority granted by the resolution, the directors intend to follow the IA's recommendations concerning its use.

As at 13 March 2024, being the latest practicable date prior to the date of this Notice of Meeting, the Company held no shares in treasury.

Special resolutions

Resolutions 16 and 17: Directors' general authority to disapply pre-emption rights and directors' specific authority to disapply pre-emption rights in connection with an acquisition or specified capital investment

Resolutions 16 and 17 will be proposed as special resolutions, each of which requires three quarters of the votes to be cast in favour. They would give the Board the power to

allot equity securities (or sell any ordinary shares which the Company holds in treasury) for cash without first offering them to existing shareholders in proportion to their existing shareholdings.

The power set out in resolution 16 would be limited to:

1. pre-emptiveoffers, 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 consider necessary; and
2. otherwise, allotments or sales up to an aggregate nominal amount of £118,400.55 (representing 2,368,011 shares and approximately 5% of the issued ordinary share capital of the Company as at 13 March 2024, the latest practicable date prior to publication of this Notice of Meeting).

Resolution 17 is intended to give the Company flexibility to make non-pre-emptive issues of ordinary shares in connection with acquisitions and other capital investments as contemplated by the Pre-Emption Group's Statement of Principles. The power under resolution 17 is in addition to that proposed by resolution 16 and would be limited to allotments or sales of up to an aggregate nominal amount of £118,400.55 (representing 2,368,011 shares and an additional 5% of the issued ordinary share capital of the Company as at 13 March 2024, the latest practicable date prior to publication of this Notice of Meeting).

In respect of the authorities sought under resolutions 16 and 17, the directors acknowledge the increased limits set out in the Pre-Emption Group's Statement of Principles published in November 2022 (the '2022 Statement of Principles'). However, at this time, the directors consider it remains appropriate to retain the previous limits of 5% of the issued ordinary share capital of the Company in resolutions 16 and 17 and have not adopted the increased limits of 10% set out in the 2022 Statement of Principles, nor do the resolutions specifically provide for follow-on offers. The directors will continue to keep emerging market practice under review but consider that the limits of 5% provide sufficient flexibility to the Company at present.

The directors have no present intention to exercise the powers sought by resolutions 16 or 17. If the powers sought by resolutions 16 or 17 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

2022 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 2022 Statement of Principles.

The powers under resolutions 16 and 17 will expire at the conclusion of the Company's next AGM or close of business on 2 August 2025, whichever is earlier.

Resolution 18: Authority to purchase own shares

Resolution 18 is a special resolution seeking approval of the renewal of the general authority from shareholders granted at last year's AGM authorising the Company to buy back its ordinary shares in the market, either for cancellation or to be held in treasury. There are a number of reasons why the directors may, in the future, consider a buy-back of shares to be in the best interests of the Company and of its shareholders generally.

These may include where the directors:

1. expect that such a buy-back would result in an increase in earnings per share;
2. consider that the Company has excess cash; and/or
3. determine that it is appropriate to increase the Company's gearing or its share liquidity.

The directors therefore consider it prudent for the Company to have the flexibility to effect market purchases of its own shares in the future.

The directors will exercise this authority only if, having due regard to the interests of long-term shareholders, they consider that to do so would be in the best interests of the Company, and of its shareholders, and (among other things) expect such purchase to result in an increase in earnings per share. In addition, the directors confirm that the decision to propose this authority for approval at the AGM has been taken by the full Board, the majority of whom are non- executive directors who do not participate in the Company's share plans and whose interest in the Company's shares is therefore unaffected by the earnings per share metric.

The Company may either retain any of its own shares which it has purchased as treasury shares with a view to possible re-issue at a future date, use them to satisfy awards under employee share plans, or cancel them. Holding the shares as treasury shares gives management the ability to re-issue them quickly and cost-effectively and would provide the Company with additional flexibility in the management of its capital base.

Under the terms of this resolution, the Company will be generally authorised to make market purchases of up to 4,736,022 shares with an aggregate nominal value of £236,801.10, representing approximately 10% of the total issued share capital of the Company as at 13 March 2024, the latest practicable date prior to the date of this Notice of Meeting. The maximum price payable per share will be based on the market price of a share as set out in more detail in the resolution itself. The minimum price payable per share, exclusive of expenses, is its nominal value.

As at 13 March 2024, being the latest practicable date prior to the date of this Notice of Meeting, the number of outstanding options to subscribe for shares granted by the Company was 1,612,350. This figure represents 3.40% of the total issued share capital of the Company at that date and would, assuming no further shares are issued, represent 4.26% of the total issued share capital if full authority to purchase shares (under the existing authority and that sought at

the AGM) were used.

The Company has not undertaken any purchases of its own shares since the date of the last AGM, but the renewal of the authority is sought to preserve flexibility. The directors have no present intention of exercising this authority, which will expire at the conclusion of the Company's next AGM or close of business on 2 August 2025, whichever is earlier.

As at 13 March 2024, being the last practicable date prior to the date of this Notice of Meeting, no shares had been purchased and held as treasury shares or cancelled under the existing authority.

Resolution 19: Notice period for general meetings

Under the Act, the notice period required for general meetings of the Company is 21 days unless shareholders approve a shorter notice period (which cannot be less than 14 clear days). AGMs are still required to be held on at least 21 clear days' notice. Approval for a shorter notice period was sought and received from shareholders at the last AGM and, to preserve this ability, resolution 19 seeks renewal of the approval for a notice period of 14 days to apply to general meetings. The shorter notice period will not be used as a matter of routine but only where clear flexibility is merited by the business of the meeting and is thought to be to the advantage of shareholders as a whole. If used, an electronic voting facility will be provided.

The approval will be effective until the conclusion of the Company's next AGM, when it is intended that a similar resolution will be proposed, or close of business on

2 August 2025, whichever is earlier.

Notice of Annual General Meeting 2024

Important notes

1. The Board is proposing to welcome shareholders in person at this year's AGM to be held at the offices of Morgan Sindall Group plc, Kent House, 14-17 Market Place, London W1W 8AJ. We will notify you of any significant updates to our AGM arrangements as soon as reasonably practicable via a Regulatory Information Service and on the 'Annual General Meeting' page of our website at www.morgansindall.com.
2. Shareholders are entitled to appoint one or more proxies (who need not be a member of the Company) to exercise all or any of their rights to attend, speak and vote at the AGM. Your proxy could be the Chair, another director of the Company or another person who has agreed to represent you. Your proxy must vote as you instruct and must attend the AGM for your vote to be counted. A proxy form, which may be used to make such appointment and give proxy instructions, accompanies this Notice of Meeting.
   A shareholder may appoint more than one proxy in relation to the AGM, provided that each proxy is appointed to exercise the rights attached to a different share or shares held by that shareholder. To appoint more than one proxy, you may photocopy the proxy form accompanying this Notice of Meeting. Please indicate the proxy holder's name and the number of shares in relation to which they are authorised to act as your proxy (which, in aggregate, should not exceed the number of shares held by you). Please also indicate if the proxy instruction is one of multiple instructions being given. All proxy forms must be signed and should be returned together in the same envelope. A failure to specify the number of shares to which each proxy appointment relates or specifying a number more than those held by you will result in the appointment being invalid.
   If you do not have a proxy form and believe that you should have one, please contact Computershare on 0370 707 1695. Lines are open from 8.30am to 5.30pm (UK time), Monday to Friday, or you can contact Computershare by email at [e-mail].
3. Voting on all resolutions will be conducted by way of a poll rather than a show of hands. This is a more transparent method of voting as member votes are counted according to the number of shares held. As soon as practicable following the meeting, the results of the voting at the meeting and the numbers of proxy votes cast for and against or actively withheld in respect of each of the resolutions will be announced on the Company's website at www.morgansindall.com and notified via a Regulatory Information Service.
4. To be valid, any proxy form or other instrument appointing a proxy must be received by post or (during normal business hours only) by hand at Computershare Investor Services PLC, The Pavilions, Bridgwater Road, Bristol BS13 8AE no later than 10.00am on Tuesday,
   30 April 2024, or in the event of an adjournment, no less than 48 hours before the stated time of the adjourned meeting (excluding any part of a day that is not a working day).

1. Shareholders may vote electronically, by no later than 10.00am on Tuesday, 30 April 2024 (or, in the event of an adjournment, no less than 48 hours before the stated time of the adjourned meeting (excluding any part of a day that is not a working day)), by visiting www.investorcentre.co.uk/eproxy. You will be asked to enter the Shareholder Reference Number, Control Number and PIN shown on either your proxy form or email and agree to certain terms and conditions. CREST shareholders may lodge their proxy via the CREST system (see notes 10 to 13). You have the right to request information from Computershare to enable you to determine that your vote on a poll was validly recorded and counted. Please contact Computershare on 0370 707 1695 to request this information. Lines are open from 8.30am to 5.30pm (UK time), Monday to Friday, or you can contact Computershare by email at [e-mail] no later than 30 days following the date of the meeting. In line with the requirements of the Companies Act 2006, the confirmation will be provided to the registered shareholder no later than 15 days from the day following the announcement of the poll results or receipt of the request, whichever is the later. The confirmation will
   be provided to registered shareholders in the manner stipulated by Computershare. Requests for confirmations must include the registered shareholder's name, address, and shareholder reference number, and confirm the name of the issuer and the date of the meeting you wish to receive a confirmation for.
2. A shareholder may change proxy instructions by returning a new proxy form using the methods set out above. If you have appointed a proxy using the hard copy proxy form but would like to change your instructions using another hard copy form, you should contact Computershare on 0370 707 1695. The above deadline for receipt of proxy forms also applies to amended instructions. Any attempt to terminate or amend a proxy form after the relevant deadline will be disregarded.
   Shareholders are strongly encouraged to appoint the
   Chair of the meeting (rather than a named person) as their proxy and to submit voting instructions in advance of the AGM.
   The valid appointment of a proxy via the return of a completed proxy form, other such instrument or any CREST Proxy Instruction (as described in note 11 below) would not prevent a shareholder from attending the AGM and voting in person if they wished.

Chair's letterNotice of meeting Explanatory notes to the resolutions Important notes

1. Any person to whom this Notice of Meeting is sent who is a person nominated under section 146 of the Act to enjoy information rights (a 'Nominated Person') may, under an agreement between them 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.
   If a Nominated Person has no such proxy appointment right or does not wish to exercise it, they may, under any such agreement, have a right to give instructions to the shareholder as to the exercise of voting rights.
2. The statement of the rights of shareholders in relation to the appointment of proxies in note 2 above does not apply to Nominated Persons. The rights described in note 2 can only be exercised by shareholders of the Company.
3. To be entitled to attend and vote at the AGM (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 6.00pm on Tuesday, 30 April 2024 (or, in the event of any adjournment, on the date which is two days before the date of any adjourned meeting (excluding any part of a day that is not a working day)). Changes to the register of members of the Company after the relevant deadline shall be disregarded in determining the rights of any person to attend and vote at the meeting.
4. CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so 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 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.
5. 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 & Ireland Limited's specifications and must contain the information required for such instruction, 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 Company's agent, Computershare Investor Services PLC (ID 3RA50), by 10.00am on Tuesday, 30 April 2024 (or, in the event of an adjournment, not less than 48 hours before the stated time of the adjourned meeting (excluding any part of a day that is not a working day)). For this purpose, the time of receipt will be taken to be the time (as determined
   by the time stamp applied to the message by the CREST Application Host) from which the Company'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.

1. CREST members and, where applicable, their CREST sponsors, or voting service providers should note that
   Euroclear UK & Ireland Limited 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, 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 system providers are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings.
2. 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.
3. 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.
4. A corporation must execute the form of proxy under its common seal or the hand of a duly authorised officer or attorney. The power of attorney or authority (if any) should be returned with the form of proxy.
5. 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 Registrar. For further information regarding Proxymity, please go to www.proxymity.io. Your proxy must be lodged by 10.00am on Tuesday,
   30 April 2024 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.
6. In the case of joint holders, where more than one joint holder purports to appoint a proxy, only the appointment submitted by the most senior holder will be accepted. Seniority is determined by the order in which the names of the joint holders appear in the Company's register of members in respect of the joint holding (the first-named being the most senior).
7. If a shareholder submits more than one valid proxy appointment, the appointment received last before the latest time for the receipt of proxies will take precedence. If the Company is unable to determine which appointment was received last, none of them will be treated as valid in respect of that share.
8. As at 13 March 2024, being the last practicable day prior to the date of this Notice of Meeting, the Company's issued share capital consisted of 47,360,226 ordinary shares, carrying one vote each. Therefore, the total voting rights in the Company as at that date are 47,360,226.
