LAPSE OF OFFER

Introduction

On 1 July 2026, the Board of Reabold, the investing company focused on developing strategic gas projects for European energy security, announced that it had reached agreement on the terms of an all share offer by Reabold for the entire issued and to be issued share capital of Union Jack, to be effected by means of a UK Takeover Code (the “Code”) offer within the meaning of Part 28 of the CA 2006 (the "Offer"). On 29 July 2026, the full terms and conditions of the Offer and the procedures for acceptance of the Offer (the “Offer Document”) were published and made available to Union Jack Shareholders.

Capitalised words and expressions in this announcement shall, unless otherwise defined, have the meaning given in the Offer Document.

As at 1:00 p.m. (London time) on 2 October 2026, Reabold had not received sufficient acceptances to satisfy the Acceptance Condition, and the Offer has now lapsed. Further details are set out in this announcement below.

Reabold observes in this light that Union Jack stated in its interim results announcement of 29 September 2026 that its newly reconstituted board of directors share Reabold’s belief that Union Jack should conduct a review of the asset portfolio, capital allocation priorities and central cost base. It was also stated that Union Jack expects to seek additional funding and is open to alternative funding arrangements, if necessary.

Reabold believes the Offer would have addressed those challenges and allowed Union Jack Shareholders to participate in a better-capitalised platform with enhanced access to funding and a wider portfolio of assets.

Day 60 acceptance level update

In accordance with Rule 31.7 of the Code, Reabold confirms that, as at 1.00 p.m. (London time) on 2 October 2026, Reabold had received valid acceptances of the Offer in respect of a total of 19,085,529 Union Jack Shares, representing approximately 13.02 per cent. of the existing issued share capital of Union Jack.

The valid acceptance received included valid acceptances from David Bramhill and Joseph O'Farrell in respect of 470,575 and 2,166,812 Union Jack Shares, respectively, pursuant to the terms of their irrevocable undertakings. Reabold is unable to confirm whether it has received valid acceptances in respect of the remaining 494,757 Union Jack Irrevocable Shares.

Acceptance Condition

As at 1:00 p.m. (London time) on 2 October 2026, Reabold may have counted 19,085,529 Union Jack Shares, representing approximately 13.02 per cent. of the existing issued share capital of Union Jack, towards satisfaction of the Acceptance Condition.

Union Jack Shareholders are reminded that the Offer was conditional, among other things, on valid acceptances of the Offer being received in respect of such number of Union Jack Shares which would result in Reabold holding Union Jack Shares carrying in aggregate more than 75 per cent. of the voting rights normally exercisable at a general meeting of Union Jack.

As such, the Acceptance Condition has not been satisfied and the Offer has now lapsed.

Reabold confirmed that neither it, nor any person acting in concert with Reabold, held any interest in relevant securities of the Union Jack prior to the commencement of the Offer and no such interests have been acquired during the Offer Period.

Further information

As the Takeover Offer has now lapsed, it is no longer open to acceptances and any accepting Union Jack Shareholders cease to be bound by their acceptances.

Reabold will now be subject to Rule 35.1 of the Code, save that Reabold reserves the right to make a further offer for the entire issued and to be issued share capital of Union Jack with the consent of the Panel, in the event that: (i) such further offer is recommended by the Union Jack Board; or (ii) a third party announces a firm intention to make an offer for Union Jack; or (iii) in the other circumstances set out in Note 1 on Rule 35.1 of the Code.

General

The percentages of Union Jack Shares referred to in this announcement are based on figures of 146,565,896 Union Jack Shares in issue as at close of business in London on 28 July 2026 (being the last Business Day prior to the publication of the Offer Document).

Forward Looking Statements

This announcement (including information incorporated by reference in this announcement), oral statements made regarding the Offer, and other information published by Union Jack or Reabold contain statements which are, or may be deemed to be, "forward looking statements". Such forward looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and on numerous assumptions regarding the business strategies and the environment in which Reabold shall operate in the future and are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied by those statements. The forward-looking statements contained in this announcement relate to Reabold’s’ future prospects, developments and business strategies, the expected timing and scope of the Offer and other statements other than historical facts. In some cases, these forward looking statements can be identified by the use of forward looking terminology, including the terms “believes”, “estimates”, “will look to”, “would look to”, “plans”, “prepares”, “anticipates”, “expects”, “is expected to”, “is subject to”, “intends”, “may”, “will”, ”seeks”, “trends”, "shall" or "should" or their negatives or other variations or comparable terminology. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that shall occur in the future. These events and circumstances include the ability to complete the Offer, the ability to obtain requisite regulatory and shareholder approvals and the satisfaction of other Conditions on the proposed terms and schedule, changes in the anticipated benefits from the proposed transaction not being realised as a result of changes in general economic and market conditions in the countries in which Reabold and Union Jack operate, changes in the global, political, economic, business, competitive, market and regulatory forces, future exchange and interest rates, changes in tax rates and future business combinations or disposals. If any one or more of these risks or uncertainties materialises or if any one or more of the assumptions prove incorrect, actual results may differ materially from those expected, estimated or projected. Such forward looking statements should therefore be construed in the light of such factors.

Neither Reabold, nor any of their respective associates or directors, officers or advisers, provides any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in this document shall actually occur. Specifically, statements of estimated cost savings and synergies relate to future actions and circumstances which, by their nature, involve risks, uncertainties and contingencies. As a result, the cost savings and synergies referred to may not be achieved, may be achieved later or sooner than estimated, or those achieved could be materially different from those estimated. Due to the scale of the Union Jack Group, there may be additional changes to the Union Jack’s Group’s operations. As a result, and given the fact that the changes relate to the future, the resulting cost synergies may be materially greater or less than those estimated. Given these risks and uncertainties, potential investors should not place any reliance on forward looking statements. The forward-looking statements speak only at the date of this document. All subsequent oral or written forward- looking statements attributable to Reabold, or any of its associates, directors, officers, employees or advisers, are expressly qualified in their entirety by the cautionary statement above.

Reabold expressly disclaims any obligation to update such statements other than as required by law or by the rules of any competent regulatory authority, whether as a result of new information, future events or otherwise.

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in 1% 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. on the 10th business day following the commencement of the offer period and, if appropriate, by no later than 3.30 p.m. 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 1% 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. 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 http://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 [phone] if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.
