NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, IN WHOLE OR IN PART, DIRECTLY OR INDIRECTLY, IN, INTO OR FROM ANY JURISDICTION WHERE TO DO SO WOULD CONSTITUTE A VIOLATION OF THE RELEVANT LAWS OR REGULATIONS OF THAT JURISDICTION

FOR IMMEDIATE RELEASE

25 August 2026

INCREASED FINAL* CASH OFFER

for

ALTERNATIVE INCOME REIT PLC ("AIRE")

by

GLENSTONE REIT PLC ("Glenstone")

Share dealing platforms are now registering instructions to accept Glenstone's Offer for AIRE ahead of this week's decision by AEW UK REIT plc ("AEWU") on its possible competing offer

Share dealing platforms are now able to receive acceptance instructions from clients holding AIRE Shares.  AIRE Shareholders who wish to accept the 70 pence per AIRE Share on offer from Glenstone must act for themselves to instruct their share dealing platform or nominee.  AEW UK REIT plc ("AEWU") must either announce a firm offer or withdraw its possible offer for AIRE this week, by Friday 28 August 2026 ("AEWU's PUSU Deadline"). 

A substantial proportion of AIRE Shares are held through retail nominee and share-dealing platforms. Glenstone understands that a number of those platforms will aggregate and submit client acceptances only very late in the Offer timetable in time to count towards the Acceptance Condition, before 1.00 p.m. on the Unconditional Date, being 4 September 2026.  

Accordingly, the acceptance figures reported by Glenstone from day to day reflect only acceptances which have actually been aggregated and submitted by the share-dealing platforms and received by the Receiving Agent at the relevant reporting time.

AIRE's retail investors can now register their instructions to accept Glenstone's 70 pence per Share cash Offer with their share dealing platforms.  Whilst all AIRE Shareholders are strongly encouraged to accept Glenstone's Offer as soon as possible, AIRE Shareholders who have been awaiting AEWU's PUSU Deadline before accepting Glenstone's Offer should now prepare to act and instruct their share dealing platforms, immediately following AEWU's announcement this week. 

AEWU's Possible Offer - PUSU deadline approaching

AEWU announced the terms of a possible all-share offer for AIRE on 16 July 2026 and now has until 5.00 p.m. on Friday 28 August 2026 either to announce a firm intention to make its offer or to confirm that it has withdrawn its possible offer for AIRE. 

Glenstone's Offer is open for acceptances for less than one week following AEWU's PUSU deadline and will remain open until 1.00 p.m. on 4 September 2026, whether AEWU announces an all-share offer for AIRE or withdraws its possible offer. 

AIRE Shareholders who have been waiting on AEWU's announcement before accepting the 70 pence per AIRE Share currently on offer from Glenstone must therefore act decisively in the next few days.

Action is required by AIRE Shareholders who wish to accept the 70 pence per AIRE Share in cash offered to them by Glenstone

Glenstone's Offer of 70 pence in cash for each AIRE Share is available for acceptance by all AIRE Shareholders.  It is a contractual takeover offer under the City Code on Takeovers and Mergers and Part 28 of the Companies Act (requiring Acceptances) and not a Scheme (which is implemented by a shareholder vote).  Therefore, any AIRE Shareholder who wishes to accept the Offer for their AIRE Shares must REGISTER THEIR INSTRUCTION TO ACCEPT THE OFFER with their share dealing platform or nominee, as applicable. 

Shareholders who do not register their acceptances cannot expect to receive the consideration of 70 pence per AIRE Share through the acceptances of other Shareholders AND MUST ACT for themselves, accordingly. 

Share dealing platforms are operating internal deadlines for the registration of instructions from accepting AIRE Shareholders, who must act well in advance of the Offer's 4 September 2026 deadline

A substantial proportion of AIRE Shareholders are retail investors who hold their AIRE Shares via share dealing platforms such as Hargreaves Lansdown, Interactive Investor and AJ Bell.  Glenstone understands that Shareholders are now able to provide instructions to most share dealing platforms, who will then register their clients' acceptances with the Receiving Agent immediately prior to 1.00 p.m. on the Unconditional Date, being Friday 4 September 2026. 

Glenstone has also been made aware that certain share dealing platforms are operating to internal deadlines which fall earlier than 4 September 2026, during the week beginning 31 August 2026.  AIRE Shareholders are encouraged to contact their share dealing platform for further information on internal procedures and deadlines.  Further information provided to Glenstone by share dealing platforms regarding their procedures and deadlines for processing clients' instructions will shortly be made available at Glenstone's website at https://www.glenstonereit.co.uk/cash-offer-for-alternative-income-reit-plc/.

All AIRE Shareholders should prepare to act in time to register their instruction to ACCEPT, in order to be eligible to receive the 70 pence per Share available to them under Glenstone's Offer.

Further Information on Glenstone's Offer

Glenstone's Offer Document and a specimen copy of the Form of Acceptance are available, subject to certain restrictions relating to persons resident in Restricted Jurisdictions, at Glenstone's website at https://www.glenstonereit.co.uk/cash-offer-for-alternative-income-reit-plc/.

*The financial terms of the Offer are final and will not be increased except that Glenstone reserves the right to revise the financial terms of the Offer if a third party announces a firm intention to make an offer for AIRE under Rule 2.7 of the Code.

Glenstone's increased final* cash Offer of 71.4 pence per AIRE Share has now been reduced to 70.0 pence per AIRE Share following the payment by AIRE of a dividend of 1.4 pence per AIRE Share on 15 August 2026 ("Fourth Quarterly Dividend").  AIRE Shareholders who accept the Offer and who held their AIRE Shares on 31 July 2026 (being the record date for the Fourth Quarterly Dividend) are entitled to retain the Fourth Quarterly Dividend in full under the terms of the Offer.

Capitalised terms used in this announcement shall, unless the context requires otherwise, have the same meanings given to them in Part VII of the offer document published by Glenstone on 6 July 2026.

Any decision or response in relation to the Offer should be made solely on the basis of the Offer Document and, where applicable, the Form of Acceptance.

Overseas AIRE Shareholders

This announcement and the Offer Document have been prepared in accordance with, and for the purpose of complying with, English law, the Code, MAR and the DTRs, and the information disclosed may not be the same as that which would have been disclosed if this announcement had been prepared in accordance with the laws of jurisdictions outside England.

The release, publication or distribution of this announcement and/or the Offer Document in, into or from jurisdictions other than the United Kingdom may be restricted by law and/or regulation and therefore any persons who are not resident in the United Kingdom or who are subject to the laws of any jurisdiction other than the United Kingdom (including Restricted Jurisdictions) should inform themselves about, and observe, any applicable legal or regulatory requirements. In particular, the ability of persons who are not resident in the United Kingdom or who are subject to the laws of any jurisdiction other than the United Kingdom to participate in the Acquisition or to accept the Offer (or, in the event the Acquisition is implemented by way of a Scheme, to vote their Scheme Voting Shares or AIRE Shares (as applicable) in respect of the Scheme at the Court Meeting or the Resolutions at the General Meeting, or to appoint another person as proxy to vote at the Court Meeting or the General Meeting on their behalf) may be affected by the laws of the jurisdictions in which they are located or to which they are subject. Any failure to comply with applicable legal or regulatory requirements of any jurisdiction may constitute a violation of securities laws in that jurisdiction. To the fullest extent permitted by applicable law, the companies, advisers and persons involved in the Acquisition disclaim any responsibility or liability for the violation of such restrictions by any person.

Unless otherwise determined by Glenstone or required by the Code, and permitted by applicable law and regulation, the Acquisition shall not be made available, directly or indirectly, in, into or from a Restricted Jurisdiction or any other jurisdiction where to do so would violate the laws or regulations in that jurisdiction and no person may accept the Offer (or, in the event that the Acquisition is implemented by way of a Scheme, vote in respect of the Scheme) by use of the mails or any other means or instrumentality (including, without limitation, facsimile, e-mail or other electronic transmission, telex or telephone) of interstate or foreign commerce of, or any facility of a national, state or other securities exchange of, any Restricted Jurisdiction or from within a Restricted Jurisdiction or any other jurisdiction if to do so would constitute a violation of the laws of that jurisdiction.

Copies of this announcement, the Offer Document and any other formal documentation relating to the Offer are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in, into or from any Restricted Jurisdiction or any other jurisdiction where to do so would constitute a violation of the laws or regulations of such jurisdiction and persons receiving such documents (including custodians, nominees and trustees) must not mail or otherwise forward, distribute or send them in, into or from any Restricted Jurisdiction or any other jurisdiction where to do so would constitute a violation of the laws or regulations of such jurisdiction. Doing so may render invalid any related purported acceptance of, or vote in respect of, the Acquisition.

If the Acquisition is implemented by way of a Scheme (unless otherwise permitted by applicable law or regulation), the Scheme Document may not be sent, supplied or made available, directly or indirectly, in or into, or by use of the mails or any other means or instrumentality (including, without limitation, facsimile, e-mail or other electronic transmission, telex or telephone) of interstate or foreign commerce of, or any facility of a national, state or other securities exchange of, any Restricted Jurisdiction and the Scheme may be voted on by any such use, means, instrumentality or facility or from within any Restricted Jurisdiction.

The availability of the Acquisition to AIRE Shareholders who are not resident in the United Kingdom may be affected by the laws of the jurisdiction in which they are resident. Persons who are not resident in the United Kingdom should inform themselves of, and observe, any applicable requirements.

Further details in relation to AIRE Shareholders in overseas jurisdictions are contained in Part V of the Offer Document.

The Acquisition is subject to the applicable requirements of the Companies Act, the Code, the Panel, the FCA, the London Stock Exchange and the Registrar of Companies (and, in the event that the Acquisition is implemented by way of a Scheme, the Court).

Notice to US shareholders in AIRE

The Acquisition relates to the shares of an English company and is expected to be implemented by means of a takeover offer provided for under the Companies Act. A transaction implemented by means of a takeover offer is not subject to the tender offer rules or the proxy solicitation rules under the US Exchange Act. The Acquisition is subject to the disclosure requirements and practices applicable to a takeover offer involving a target company in England whose shares are traded on the main market of the London Stock Exchange, which differ from the US disclosure requirements in certain respects.

The financial information included in the Offer Document (or, if the Acquisition is implemented by way of a Scheme, the Scheme Document) has been or will have been prepared in accordance with accounting standards applicable in the United Kingdom and may not therefore be comparable to the financial information of United States 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 accounting standards applicable in the United Kingdom.

The receipt of cash pursuant to the Acquisition by US AIRE Shareholders may be a taxable transaction for US federal income tax purposes and under applicable US state and local, as well as foreign and other, tax laws. Each AIRE Shareholder (including each US AIRE Shareholder) is urged to consult their own independent professional adviser immediately regarding the legal and tax consequences of the Acquisition applicable to them.

Neither the Securities and Exchange Commission nor any US state securities commission has approved or disapproved or passed judgment upon the fairness or the merits of the Acquisition or determined if this announcement and/or the Offer Document is adequate, accurate or complete. Any representation to the contrary is a criminal offence in the US.

Each of AIRE and Glenstone is incorporated under the laws of England and Wales. In addition, most of their respective officers and directors reside outside the US, and some or all of their respective assets are or may be located in jurisdictions outside the US. Therefore, investors may have difficulty effecting service of process within the US upon those persons or recovering against AIRE or Glenstone or their respective officers or directors on judgments of US courts, including judgments based upon the civil liability provisions of US federal 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. It may not be possible to sue AIRE or Glenstone or their respective officers or directors in a non-US court for violations of US securities laws.

In accordance with normal United Kingdom practice and pursuant to Rule 14e-5 of the US Exchange Act, to the extent applicable, Glenstone or its nominees or brokers (acting as agents) may from time to time make certain purchases of, or arrangements to purchase, AIRE Shares, other than pursuant to the Acquisition, while the Offer remains open to acceptance, in compliance with applicable law, including the US Exchange Act. Any information about such purchases will be disclosed as required in the United Kingdom, will be reported via a Regulatory Information Service and will be available on the London Stock Exchange website at: http://www.londonstockexchange.com.

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in one per cent. or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the offer period and, if later, following the announcement in which any securities exchange offeror is first identified. An Opening Position Disclosure must contain details of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3.30 p.m. (London time) on the 10th business day following the commencement of the offer period and, if appropriate, by no later than 3.30 p.m. (London time) on the 10th business day following the announcement in which any securities exchange offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in one per cent. or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s), save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 p.m. (London time) on the business day following the date of the relevant dealing.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4).

Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Panel's website at www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the offer period commenced and when any offeror was first identified. You should contact the Panel's Market Surveillance Unit on +44 (0)20 7638 0129 if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.
