COMPLETION OF COMBINATION AND TRADING UPDATE

Capturing rental growth and capitalising on increasing occupational activity

Tritax Big Box REIT plc ("BBOX" or the "Company") is pleased to announce that the Scheme of Arrangement (the "Scheme") in respect of the all share combination of BBOX and UK Commercial Property REIT Limited ("UKCM") became effective on 16 May 2024 (the "Effective Date") and that admission of 576,939,134 New BBOX Shares is expected today at 8.00 a.m. ("Admission").

Colin Godfrey, CEO commented:

"Following very strong support from both sets of shareholders, we are pleased to announce the completion of the acquisition of UKCM and are delighted to welcome our new shareholders to BBOX.

"The combination complements our big box weighted investment portfolio with high-quality urban logistics assets enhancing our customer offering and driving accelerated rental growth through early capture of significant rental reversion. The liquid nature of the non-strategic parts of the UKCM portfolio is reflected in the number of inbound enquiries we have received which will facilitate the accretive rotation of capital into the development of brand new best-in-class logistics assets.

"We are seeing an encouraging uptick in levels of activity in our development pipeline. Many occupiers that deferred decision making in 2023 have moved forward in 2024 and we have 1.5 million sq ft of new development transactions in legals, and a strong pipeline in negotiations. In addition, freehold development sales are expected to contribute at least £15 million of DMA income in the year. Through rent reviews, lettings and regears we are making good progress capturing the significant reversion within our investment portfolio. In addition, we continue to take advantage of market conditions to selectively acquire mispriced assets. These factors together with stabilised yields collectively support our positive outlook for 2024."

Additional Information for US Investors

The Combination relates to the shares of a Guernsey company with a listing on the London Stock Exchange and is proposed to be implemented pursuant to a scheme of arrangement provided for under Guernsey company law. A transaction effected by means of a scheme of arrangement is not subject to the proxy solicitation or the tender offer rules under the US Exchange Act. Accordingly, the Combination is subject to the procedural and disclosure requirements, rules and practices applicable in the United Kingdom or Guernsey involving a target company incorporated in Guernsey and listed on the London Stock Exchange, which differ from the requirements of US proxy solicitation or tender offer rules. Financial information included in this Announcement and the Scheme Document has been prepared in accordance with UK IFRS or EU IFRS and thus may not be comparable to financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States. Generally accepted accounting principles in the United States differ in certain significant respects from UK IFRS and EU IFRS.

The New BBOX Shares have not been and will not be registered under the US Securities Act or under the securities laws of any state or other jurisdiction of the United States. Accordingly, the New BBOX Shares may not be offered, sold, resold, delivered, distributed or otherwise transferred, directly or indirectly, in or into or from the United States absent registration under the US Securities Act or an exemption therefrom and in compliance with the securities laws of any state or other jurisdiction of the United States. The New BBOX Shares are expected to be issued in reliance upon the exemption from the registration requirements of the US Securities Act provided by section 3(a)(10) thereof.

None of the securities referred to in this Announcement have been approved or disapproved by the SEC, any state securities commission in the United States or any other US regulatory authority, nor have such authorities passed upon or determined the fairness or merits of such securities or the Combination or upon the adequacy or accuracy of the information contained in this Announcement. Any representation to the contrary is a criminal offence in the United States.

It may be difficult for US holders of UKCM Shares to enforce their rights and claims arising out of the US federal securities laws, since BBOX and UKCM are organised in countries other than the United States, and some or all of their officers and directors may be residents of, and some or all of their assets may be located in, jurisdictions other than the United States. US holders of UKCM Shares may have difficulty effecting service of process within the United States upon those persons or recovering against judgments of US courts, including judgments based upon the civil liability provisions of the US federal securities laws. US holders of UKCM Shares may not be able to sue a non-US company or its officers or directors in a non-US court for violations of US securities laws. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court's judgment.

The receipt of New BBOX Shares pursuant to the Combination by a US UKCM Shareholder may be a taxable transaction for US federal income tax purposes, and may also be a taxable transaction under applicable state and local tax laws, as well as foreign and other tax laws. Each UKCM Shareholder is urged to consult its independent professional adviser immediately regarding the tax consequences of the Combination.
