Notes

1. Members are entitled to appoint one or more proxies (who need not be Shareholders) to exercise all or any of their rights to vote on their behalf at the meeting and at any adjournment of it. A member may appoint more than one proxy in relation to the meeting, provided that each proxy is appointed to exercise the rights attached to a different share or shares held by that member.

If a proxy appointment is submitted without indicating how the proxy should vote on any resolution, the proxy will have discretion as to whether and, if so, how they vote.

1. A Form of Proxy which may be used to make such appointment and give proxy instructions accompanies this Notice. If you do not have a Form of Proxy and believe that you should have one, or if you require additional forms, please contact Computershare Investor Services PLC on +44 (0370) 702 0147.

Members may also appoint a proxy online at www.investorcentre. co.uk/eproxy (more details can be found in the Form of Proxy) or, for members of CREST, through CREST electronic proxy appointment service (as described in note 12 below) or via the Proxymity platform (as described in note 13 below).

• 1. To be valid, any proxy instructions must be received by post or by hand (during normal business hours only) by Computershare Investor Services PLC, The Pavilions, Bridgwater Road, Bristol, BS99 6ZY, or at www.investorcentre.co.uk/eproxy, in each case no later than 10.00 a.m. on Friday 2 May 2025, together with, if appropriate, the power of attorney or other authority (if any) under which it is signed or a duly certified copy of that power or authority.
• 1. Any person to whom this Notice is sent who is a person nominated under Section 146 of the Companies Act 2006 (the "Act") to enjoy information rights (a "Nominated Person") may have a right, under an agreement between him/her and the member by whom he/she was nominated, to be appointed (or to have someone else appointed) as a proxy for the meeting. If a Nominated Person has no such proxy appointment right or does not wish to exercise it, he/she may have a right, under such an agreement, to give instructions to the member as to the exercise of voting rights. The statement of the above rights of the members in relation to the appointment of proxies does not apply to Nominated Persons. Those rights can only be exercised by members of the Company.
• 1. A vote withheld option is provided on the Form of Proxy to enable you to instruct your proxy not to vote on any particular resolution; however, it should be noted that a vote withheld in this way 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.
• 1. To be entitled to vote (and for the purpose of determining the number of votes members may cast), members must be registered in the register of members of the Company at 5.30 p.m. on Friday 2 May 2025 (or, in the event of any adjournment, 5.30 p.m. 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.
• 1. In the case of joint holders, where more than one of the joint holders 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).
• 1. If a member submits more than one valid proxy appointment in respect of the same shares, the appointment received last before the latest time for the receipt of proxies will take precedence.
• 1. Any corporation which is a member can appoint one or more corporate representatives who may exercise on its behalf all of its powers as a member provided that they do not do so in relation to the same shares.
• 1. Any member attending the meeting has the right to ask questions. Alternatively, as noted in the Chair's letter, Shareholders can ask questions or raise matters of concern by emailing the Company Secretary at company.secretary@tritaxbigbox.co.uk by 5.30 p.m. on Friday 2 May 2025. Such questions will be answered ahead of the meeting. The Company must cause to be answered any questions relating to the business being dealt with at the meeting but no such answer need be given if (i) to do so would interfere unduly with the preparation for the meeting or would involve the disclosure of confidential information or (ii) the answer has already been given on a website in the form of an answer to a question or (iii) it is undesirable in the interests of the Company or the good order of the meeting that the question be answered.
• 1. As at Monday 31 March 2025 (being the latest practicable date prior to the publication of this Notice) the Company's issued share capital consists of 2,480,677,459 Ordinary Shares, carrying one vote each. Therefore, the total voting rights in the Company as at Monday 31 March 2025 are 2,480,677,459.

Notice of Annual General Meeting continued

Notes continued

1. CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the meeting 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.

Please note the following:

(a) 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 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 3RA50 by the latest time(s) for receipt of proxy appointments specified in this Notice. 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 Application 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.

• (b) CREST members and, where applicable, their CREST sponsors or voting service provider(s) should note that Euroclear UK & International Limited does not make available 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/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 provider(s) are referred in particular to those sections of the CREST Manual concerning practical limitations of the CREST system and timings.
• (c) 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.
• 1. 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 10.00 a.m. on Friday 2 May 2025 in order 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.
• 1. Copies of the letters of appointment of the Non-Executive Directors will be available for inspection upon request from the Company Secretary during normal business hours from Tuesday 1 April 2025 until the conclusion of the meeting (Saturdays, Sundays and public holidays excepted).
• 1. Copies of this Notice, and other information required by Section 311A of the Act, can be found at https://www.tritaxbigbox.co.uk /investors/shareholder-information/.
• 1. You may not use any electronic address (within the meaning of Section 333(4) of the Act) provided in this Notice (or in any related documents including the Form of Proxy) to communicate with the Company for any purposes other than those expressly stated.
• 1. Under Section 527 of the Act, members meeting the threshold requirements set out in that section have the right to require the Company to publish on a website a statement setting out any matter relating to: (i) the audit of the Company's accounts (including the Auditor's Report and the conduct of the audit) that are to be laid before the AGM; or (ii) any circumstance connected with an auditor of the Company ceasing to hold office since the previous meeting at which annual accounts and reports were laid in accordance with Section 437 of the Act, (in each case) that the members propose to raise at the AGM. The Company may not require the members requesting any such website publication to pay its expenses in complying with Sections 527 or 528 of the Act. Where the Company is required to place a statement on a website under Section 527 of the Act, it must forward the statement to the Company's Auditor not later than the time when it makes the statement available on the website. The business which may be dealt with at the meeting includes any statement that the Company has been required under Section 527 of the Act to publish on a website.

Explanatory notes

The notes on the following pages give an explanation of the proposed resolutions.

Resolutions 1 to 13 (inclusive) 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 14 to 17 (inclusive) are proposed as special resolutions. This means that for each of those resolutions to be passed, at least three-quarters of the votes cast must be in favour of the resolution.

Report and accounts (Resolution 1)

This resolution is to receive and adopt the accounts for the financial year ended 31 December 2024 and the associated reports of the Directors and Auditor.

Directors' Remuneration Report (Resolution 2)

This resolution is to approve the Directors' Remuneration Report (other than the part containing the Directors' Remuneration Policy) for the financial year ended 31 December 2024. You can find this report on pages 111 to 113 of the Company's Annual Report and Accounts for the financial year ended 31 December 2024. As this vote is an advisory vote, no entitlement of a Director to remuneration is conditional on it. This resolution is required to be put to a vote annually under Section 420(1) of the Companies Act 2006.

Election and re-election of Directors (Resolutions 3 to 9)

Resolution 3 is to approve the election of Kirsty Wilman as Director of the Company. Resolutions 4 to 9 (inclusive) are to approve the re-election of Aubrey Adams, Elizabeth Brown, Wu Gang, Alastair Hughes, Richard Laing and Karen Whitworth as Directors of the Company.

In accordance with the Company's Articles of Association, Directors appointed by the Board are required to submit themselves for election at the first Annual General Meeting following their appointment. The Board recommends that Kirsty Wilman, who was appointed as a Director by the Board on 1 September 2024, is elected as a Director of the Company. All other Directors who are Directors at the date of this Notice shall retire from office at the Annual General Meeting and will be subject to re-election.

The Directors are committed to measures that promote good corporate governance. The Board is satisfied that each of the Directors standing for election and re-election continues to perform effectively and demonstrates commitment to their respective roles.

Short biographical details of each of the Directors standing for election and re-election are set out on pages 80 and 81 of the Company's Annual Report.

Appointment and remuneration of the Auditor (Resolutions 10 and 11)

Resolution 10 proposes the re-appointment of BDO LLP as Auditor of the Company and Resolution 11 authorises the Directors to set the Auditor's remuneration.

Dividend payment (Resolution 12)

The Company currently pays four dividends per annum and to date these have been declared as "interim" dividends. The alternative to this would be to declare three interim dividends with the final dividend being proposed as a "final" dividend.

A final dividend, however, would require Shareholder approval which would delay the payment. To avoid this potential delay, the Company has proposed a dividend policy, annually, that enables the Company to pay all of its dividends as "interim" dividends and for the last dividend not to be categorised as a "final" dividend that would ordinarily be subject to Shareholder approval.

Having regard to corporate governance best practice relating to the payment of interim dividends without the approval of a final dividend by a company's shareholders, the Directors have decided to seek express approval from Shareholders of its policy to pay four interim dividends per year. Should this resolution be approved, it will be valid until the conclusion of the Company's next Annual General Meeting in 2026, when it is intended that a similar resolution will be proposed.

It should be noted that the dividend policy is not a profit forecast and if dividends are declared by the Directors, they will only be paid to the extent permitted in accordance with the Companies Act 2006.

Directors' authority to allot shares (Resolution 13)

The Directors may allot shares and grant rights to subscribe for, or convert any security into, shares only if authorised to do so by Shareholders.

Accordingly, Resolution 13 will be proposed as an ordinary resolution to grant the Directors authority to allot shares and grant rights to subscribe for, or convert any security into, shares in the Company (a) up to a nominal value of £8,268,924 (826,892,400 Ordinary Shares), which is equivalent to approximately one-third of the total issued ordinary share capital of the Company as at Monday 31 March 2025 (being the latest practicable date prior to the publication of this Notice); and (b) in connection with a fully pre-emptive offer up to an aggregate nominal value of £16,537,849 (1,653,784,900 Ordinary Shares), which is (before any reduction) approximately two-thirds of the Company's issued share capital as at Monday 31 March 2025.

This is in line with corporate governance guidelines. The Directors have no present intention of using this authority. However, if they do exercise the authority, the Directors intend to take note of relevant corporate governance guidelines in the use of such powers.

As at Monday 31 March 2025 (being the latest practicable date prior to the publication of this Notice), the Company did not hold any shares in treasury.

If the resolution is passed, the authority will expire on the earlier of the conclusion of the next Annual General Meeting of the Company in 2026 or, if earlier, on the date falling 15 months after the passing of the resolution.

Disapplication of pre-emption rights (Resolutions 14 and 15)

If the Directors wish to allot equity securities or sell treasury shares for cash, company law requires that these shares are first offered to existing Shareholders in proportion to their existing holdings.

There may be occasions, however, when the Directors will need the flexibility to finance investment opportunities identified by the Company's investment manager (in accordance with the Company's investment policy) by the issue of Ordinary Shares without a pre-emptive offer to existing Shareholders. The Directors require a power from Shareholders to do so.

Accordingly, Resolution 14 will be proposed as a special resolution to grant the Directors power to allot equity securities or sell treasury shares for cash and 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 power will be limited to the allotment of equity securities and sales of treasury shares for cash up to an aggregate nominal value of £1,240,338 (which is equivalent to approximately 5% of the Company's issued ordinary share capital as at Monday 31 March 2025, being the latest practicable date prior to the publication of this Notice).

Resolution 14 also seeks a disapplication of the pre-emption rights on a rights issue or other fully pre-emptive issue so as to allow the Directors to make exclusions or such other arrangements as may be appropriate to resolve legal, regulatory or practical difficulties which, for example, might arise with overseas Shareholders.

Disapplication of pre-emption rights (Resolutions 14 and 15) continued

The Directors seek further power under Resolution 15 to allot equity securities or sell treasury shares for cash and otherwise than to existing Shareholders pro rata to their holdings. Resolution 15 will be proposed as a special resolution. The power will be limited to the allotment of equity securities and sales of treasury shares for cash up to an aggregate nominal value of £1,240,338 (which is equivalent to approximately 5% of the Company's issued ordinary share capital as at Monday 31 March 2025) in connection with the financing (or refinancing, if the power is to be used within twelve months after the original transaction) of a transaction which the Directors determine to be an acquisition or other capital investment of a kind contemplated by the Statement of Principles. This is in addition to the 5% referred to in Resolution 14.

The Company undertakes that Ordinary Shares will only be issued pursuant to these authorities at a premium to the prevailing Net Asset Value at the time of issue, unless specifically approved by Shareholders in a general meeting.

Resolutions 14 and 15 have been separated in accordance with the guidance issued by the Pre-Emption Group.

If given, the powers contained in Resolutions 14 and 15 will each expire at the conclusion of the next Annual General Meeting of the Company in 2026 or, if earlier, on the date falling 15 months after the passing of the resolutions.

The figure of up to 5% reflects the Pre-Emption Group's Statement of Principles (as updated in March 2015). The Directors are aware of the Pre-Emption Group's most recent Statement of Principles on Disapplying Pre-emption Rights published in November 2022 (the "2022 Statement of Principles"). However, at this time, the Directors consider it appropriate to retain the previous limits of 5% of the issued ordinary share capital of the Company in Resolutions 14 and 15 and have not adopted the increased limits. The Directors will keep emerging market practice under review.

The Directors confirm that they will follow the shareholder protections in paragraph one of Part 2B of the 2022 Statement of Principles.

Authority to purchase own shares (Resolution 16)

In certain circumstances, it may be advantageous for the Company to purchase its own shares and Resolution 16 seeks the authority from Shareholders to continue to do so. Resolution 16 will be proposed as a special resolution. The Directors will exercise this authority at their absolute discretion only when, in the light of market conditions prevailing at the time, they believe that the effect of such purchases will be to increase earnings per share and will be in the best interests of the Company and Shareholders generally.

The Directors have not exercised the authority to purchase own shares approved at the Company's 2024 Annual General Meeting in the last twelve months. Furthermore, the Directors currently have no intention of exercising this authority but will keep the matter under review, taking into account factors including (without limitation) market conditions, the financial resources of the Company, the Company's share price, appropriate gearing levels, other investment opportunities and the overall position of the Company.

Any shares purchased in this way may either be cancelled (and the number of shares in issue will be reduced accordingly) or, in accordance with the Companies Act 2006, retained as treasury shares.

This would give the Company the ability to re-issue treasury shares quickly and cost-effectively and provides the Company with greater flexibility in the management of its capital base.

Once held in treasury, the Company is not entitled to exercise any rights, including the right to attend and vote at meetings, in respect of the shares. Further, no dividend or other distribution of the Company's assets may be made to the Company in respect of the treasury shares.

The resolution specifies the maximum number of Ordinary Shares that may be acquired (approximately 10% of the Company's issued ordinary share capital as at Monday 31 March 2025, being the latest practicable date prior to the publication of this Notice) and the maximum and minimum prices at which they may be bought.

There are no warrants or options to subscribe for Ordinary Shares outstanding as at Monday 31 March 2025.

If given, this authority will expire at the conclusion of the next Annual General Meeting of the Company in 2026 or, if earlier, on the date falling 15 months after the passing of the resolution.

General meetings: length of notice (Resolution 17)

The Companies Act 2006 requires the Company to give at least 21 clear days' notice for a general meeting of the Company (other than Annual General Meetings) unless the Company:

• (a) has obtained Shareholder approval for the holding of general meetings on shorter notice, which cannot be less than 14 clear days; and
• (b) offers the facility for all Shareholders to vote by electronic means.

Resolution 17 seeks such approval and will be proposed as a special resolution. The minimum notice period for Annual General Meetings remains at least 21 clear days' notice. This authority would provide the Company with flexibility where action needs to be taken quickly. It is intended that this shorter notice period would not be used as a matter of routine but only where the flexibility is merited by the business of the meeting and is thought to be in the interests of Shareholders as a whole.

Should this resolution be approved, it will be valid until the conclusion of the Company's next Annual General Meeting in 2026, when it is intended that a similar resolution will be proposed.
