Recommended All Share Offer

for

Union Jack Oil plc ("Union Jack")

by

Reabold Resources plc ("Reabold")

The Board of Reabold, the investing company focused on developing strategic gas projects for European energy security, is pleased to announce that they have reached agreement on the terms of a recommended all share offer by Reabold for 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").

The boards of Union Jack and Reabold believe that the Offer has a compelling strategic rationale, creating a more substantial and better capitalised oil and gas investment company with complementary assets and aligned objectives. The Offer is expected to deliver benefits to shareholders and other stakeholders of both companies, including enhanced scale, improved access to capital and a broader, more diversified portfolio. The all-share nature of the Offer enables Union Jack Shareholders to participate in the future value creation of the Enlarged Group, while Reabold Shareholders are expected to benefit from increased exposure to producing and development assets and the potential for operational efficiencies and disciplined capital allocation across a combined asset base.

In addition, having undertaken an extensive review of Union Jack's strategic and financing options, and having carefully considered the alternatives available, the board of Union Jack has concluded that no alternative proposal capable of providing the funding required to execute Union Jack's strategy is currently available on acceptable terms. 

In the absence of such funding or the Offer, the board of Union Jack is of the view that Union Jack will, in the short term, be unable to meet its licence commitments, which, in accordance with the licence terms, may result in the forfeiture of key assets within the Union Jack portfolio.

The board of Union Jack believes that the Offer provides the only financing option to prevent this outcome and is therefore of the view that the Offer is in the best interests of shareholders.

Given the foregoing, the board of Union Jack welcomes that the Acceptance Condition has been set at a level that requires Reabold to acquire or contract to acquire shares carrying only approximately 75 per cent. of the voting rights normally exercisable at a general meeting of Union Jack.

Summary

· Under the terms of the Offer, each shareholder of Union Jack ("Union Jack Shareholders") will be entitled to receive:

 0.051 New Reabold Share(s) in exchange for every 1 Union Jack Share(s)

· The terms of the Offer value each Union Jack Share at approximately 4.19 pence, based on an exchange ratio of 0.051 new Reabold Shares for each Union Jack Share and Reabold's closing share price of 81.0 pence on the Latest Practicable Date (the "Offer Value") prior to the publication of this announcement (being 30 June 2026) (the "Announcement").

· The Offer Value implies Union Jack's entire issued, and to be issued, share capital is valued at approximately £6.14 million on a fully diluted basis.

· Upon Completion of the Offer, the Enlarged Group will have a combined market capitalisation of approximately £17.80 million (assuming full acceptance of the Offer), with Union Jack Shareholders expected to own approximately 34.01 per cent. of the Enlarged Group.

· The Offer Value represents a premium of approximately:

- 25.0 per cent. to Union Jack's closing share price of 3.35 pence on 12 June 2026, being the latest trading date prior to the publication of the statement regarding a possible offer from Reabold (the "Relevant Date"); and

- 6.1 per cent. to the volume weighted average price of 3.95 pence per Union Jack Share for the three months ended on the Relevant Date.

· The share-for-share offer provides Union Jack Shareholders with the opportunity to participate in the future upside of the Enlarged Group through ownership of shares in a larger, more diversified and more liquid AIM-listed company.

Background to and reasons for the Offer

Reabold submitted a non-binding indicative proposal to the Union Jack Board on 5 June 2026 regarding a possible all-share offer, following which the parties engaged in discussions and Reabold conducted confirmatory due diligence on Union Jack's business and assets. Following this process, the boards of Reabold and Union Jack reached agreement on the terms of a recommended all-share offer.

The Reabold Board believes the Offer has a compelling strategic rationale, combining two complementary UK-focused onshore oil and gas businesses to create a larger, more diversified and better capitalised group. The Enlarged Group is expected to benefit from increased scale, broader asset exposure (including producing and development assets), improved access to capital and enhanced ability to progress key projects.

The combination is also expected to deliver operational and corporate efficiencies, including optimised development planning across shared assets and more effective capital allocation, allowing a greater proportion of capital to be deployed directly into asset development and value creation. The all-share structure allows Union Jack Shareholders to participate in the future upside of the Enlarged Group, while providing Reabold Shareholders with increased exposure to a broader portfolio with enhanced near-term cash flow potential.

Reabold is well-funded for its upcoming work programme, including the West Newton recompletion, and has recently demonstrated continued access to capital through the successful raising of £4.16 million through the issue of equity at the prevailing market price. For Union Jack Shareholders, the Offer provides an opportunity to realise an immediate premium while also gaining increased exposure to the development upside of West Newton as well as the broader Reabold portfolio within a larger, better capitalised platform.

Recommendation

The Union Jack Directors, who have been so advised by Gneiss as to the financial terms of the Offer, consider the terms of the Offer to be fair and reasonable. In providing its advice to the Union Jack Directors, Gneiss has taken into account the commercial assessments of the Union Jack Directors. Gneiss is providing independent financial advice to the Union Jack Directors for the purposes of Rule 3 of the Code.

In addition, having undertaken an extensive review of Union Jack's strategic and financing options, and having carefully considered the alternatives available, the board of Union Jack has concluded that no alternative proposal capable of providing the funding required to execute Union Jack's strategy is currently available on acceptable terms. 

In the absence of such funding or the Offer, the board of Union Jack is of the view that Union Jack will, in the short term, be unable to meet its licence commitments, which, in accordance with the licence terms, may result in the forfeiture of key assets within the Union Jack portfolio.

The board of Union Jack believes that the Offer provides the only financing option to prevent this outcome and is therefore of the view that the Offer is in the best interests of shareholders.

Given the foregoing, the board of Union Jack welcomes that the Acceptance Condition has been set at a level that requires Reabold to acquire or contract to acquire shares carrying only approximately 75 per cent. of the voting rights normally exercisable at a general meeting of Union Jack.

Accordingly, the Union Jack Directors intend to unanimously recommend that the Union Jack Shareholders accept the Offer, as all of the Union Jack Directors who are interested in Union Jack Shares have irrevocably undertaken to do (or procure to be done) in respect of their own holdings (and those of their connected parties) of, in aggregate, 3,132,144 Union Jack Shares, representing, in aggregate, approximately 2.14 per cent. of the issued ordinary share capital of Union Jack as at the Latest Practicable Date. These undertakings will remain binding in the event of a competing offer being made.

Considerations for the Recommendation

The Union Jack Directors believe that the combination of Union Jack and Reabold will create a strengthened onshore oil and gas company with a balanced portfolio of near-term production, appraisal and high-impact development opportunities. The Enlarged Group would benefit from enhanced scale, a simplified corporate structure, and an improved platform.

Specific other considerations for the recommendation of the Offer include:

Portfolio consolidation and enhanced exposure to core UK assets

· A combined portfolio centred on a number of high-quality UK onshore licences, including material interests in producing and near-production assets including Wressle and West Newton, providing increased exposure across a range of development stages.

· Greater alignment of interests across certain key licences where both companies currently hold positions, enabling more efficient decision-making, streamlined governance and accelerated development execution.

· A diversified portfolio spanning cash-generative production, appraisal upside and longer-term development opportunities, enhancing resilience across commodity price cycles.

Improved scale and funding flexibility

· The Enlarged Group is expected to benefit from increased market capitalisation and liquidity, positioning it as a more relevant and investable vehicle within the UK small-cap E&P sector.

· Enhanced financial flexibility, supported by a combined cash position, production revenues and reduced duplication of corporate overheads, enabling more efficient capital allocation across the portfolio.

· Greater capacity to access external funding, including both equity and debt markets, on more favourable terms, supporting the advancement of key development projects.

Acceleration of value realisation from core projects

· Increased working interests in key projects are expected to enhance exposure to production and development upside.

· A more coordinated strategy for progressing appraisal and development assets, with the aim of unlocking material contingent resource potential through technical de-risking and development planning.

Strategic and operational synergies

· A strong strategic fit between the two companies, with highly complementary asset bases, overlapping geographic focus and aligned operational priorities.

· Opportunities to realise cost synergies through the elimination of duplicated corporate functions and the rationalisation of administrative and public company costs.

Enhanced market positioning

· The creation of a larger, more diversified entity is expected to improve visibility with institutional investors, potentially increasing trading liquidity and broadening the shareholder base.

· A more compelling investment proposition, combining production cash flow with significant development and appraisal upside, positioning the Combined Group as a differentiated onshore E&P platform.

Attractive transaction terms

· The terms of the Offer provide Union Jack Shareholders with exposure to a broader and more diversified portfolio, together with the potential for enhanced long-term value creation through the Enlarged Group.

The implied valuation of the Offer represents a premium of approximately 25.0 per cent. to Union Jack's closing share price of 3.35 pence on the Relevant Date with material upside potential through ownership of the Enlarged Group.

Irrevocable Undertakings

All of the Directors of Union Jack who currently beneficially hold or control Union Jack shares have provided irrevocable undertakings to accept the Offer in respect of 3,132,144 Union Jack Shares, representing approximately 2.14 per cent. of the issued ordinary share capital of Union Jack as at the Latest Practicable Date.

These irrevocable undertakings remain binding in the event a higher competing offer is made for Union Jack.

Further details of these irrevocable undertakings, including the circumstances in which they may lapse, are set out in paragraph 8 of this Announcement and in Appendix III to this Announcement.

Structure and Level of Acceptances

It is intended that the Offer be effected by means of a takeover offer within the meaning of Part 28 of the CA 2006.

The Offer is conditional upon Reabold having received valid acceptances (which have not been withdrawn) by no later than 1.00 p.m. (London time) on the Unconditional Date (or such later time(s) and/or date(s) as Reabold may specify, subject to the rules of the Code and, where applicable, with the consent of the Panel) in respect of not less than 75 per cent. (75%) (or such lower percentage as Reabold may decide) in value of the total Union Jack Shares to which the Offer relates and of the voting rights attached to those shares (the "Acceptance Condition"), provided that Reabold has acquired or agreed to acquire pursuant to the Offer or otherwise more than 50 per cent. (50%) of the voting rights then exercisable at a general meeting of Union Jack (the "Minimum Acceptance Threshold"). The Offer will also be subject to the NSTA Condition, the passing of the Reabold Shareholder Resolution at the Reabold General Meeting, the Admission Condition and all the other Conditions and certain further terms set out in Appendix I to this announcement being satisfied or (if capable of waiver) waived.

Information on the full details of the Offer and the expected timetable is set out in Appendix I and will be set out in an offer document, which Reabold will despatch to Union Jack Shareholders in due course (subject to certain restrictions relating to persons residing in Restricted Jurisdictions) ("Offer Document"). Subject to the same restrictions, the Offer Document will be made available by Reabold on its website at www.reabold.com and the website of Union Jack at www.unionjackoil.com.

Commenting on the Offer, Jeremy Edelman, Chairman of Reabold, said:

"We believe the proposed combination with Union Jack represents a compelling opportunity for Reabold shareholders. It would create a larger, more diversified and better capitalised company with a strengthened UK onshore oil and gas platform, providing balanced exposure to producing and development assets, improved access to funding, and the potential to deliver long-term shareholder value through increased scale, operational efficiencies, strategic synergies and disciplined capital allocation."

Commenting on the Offer, David Bramhill, Executive Chairman of Union Jack, said:

"The Offer has a compelling strategic rationale, creating a more substantial and better capitalised oil and gas company with complementary assets and aligned objectives. The combination of Union Jack and Reabold will create a strengthened onshore oil and gas company in both the UK and internationally with a balanced portfolio of near-term production, appraisal and high-impact development opportunities in the pursuit of future value creation. The combination will deliver a better capitalised business and more diversified portfolio with enhanced scale in the UK and increased international reach and the Offer will enable Union Jack Shareholders to participate in the future value creation of the Enlarged Group.

In addition, having undertaken an extensive review of Union Jack's strategic and financing options, and carefully considered the alternatives available, the board of Union Jack has concluded that no alternative proposal capable of providing the funding required on acceptable terms to execute Union Jack's strategy is currently available. In the absence of such funding or the Offer, the board of Union Jack is of the view that Union Jack will, in the short term, be unable to meet its licence commitments, which in accordance with the licence terms, may result in the forfeiture of key assets within the Union Jack portfolio. The board of Union Jack believes that the Offer provides the only financing option to prevent this outcome and are therefore of the view that the Offer is in the best interests of shareholders."

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.

No profit forecasts or estimates

No statement in this Announcement is intended or shall be deemed to be a profit forecast, estimate or projection of the future financial performance of Reabold or Union Jack for any period except as otherwise stated and no statement in this Announcement should be interpreted to mean that cashflow from operations, earnings or earnings per share or income of those persons (where relevant) for the current or future financial years would necessarily match or exceed the historical published cashflow from operations, earnings or earnings per share or income of those persons (where relevant).

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.

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).

Recommended All Share Offer

for

Union Jack Oil plc ("Union Jack")

by

Reabold Resources plc ("Reabold")

1. Introduction

The Board of Reabold, the investing company focused on developing strategic gas projects for European energy security, is pleased to announce that they have reached agreement on the terms of a recommended all share offer by Reabold for 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").

2. The Offer

Under the terms of the Offer, which shall be subject to the Conditions and further terms set out in Appendix I and, in respect of Union Jack Shares held in certificated form, Union Jack Shareholders will be entitled to receive:

0.051 New Reabold Share(s) in exchange for every 1 Union Jack Share(s)

The New Reabold Shares will be issued credited as fully paid and will rank pari passu in all respects with the Reabold Shares already in issue, including the right to receive and retain dividends and other distributions.

Upon the Offer becoming or being declared unconditional in all respects and assuming Reabold acquires all of the fully diluted share capital of Union Jack, Union Jack Shareholders will own approximately 34.01 per cent. of the share capital of the Enlarged Group (based on the fully diluted share capital of Reabold and the fully diluted share capital of Union Jack, in each case as at the Latest Practicable Date).

The terms of the Offer value each Union Jack Share at approximately 4.19 pence, based on an exchange ratio of 0.051 new Reabold Shares for each Union Jack Share and Reabold's closing share price of 81.0 pence on the Latest Practicable Date prior to the publication of the Announcement.

The Offer Value implies Union Jack's entire issued, and to be issued, share capital is valued at approximately £6.14 million on a fully diluted basis.

The Offer Value represents a premium of approximately:

· 25.0 per cent. to Union Jack's closing share price of 3.35 pence on 12 June 2026, being the latest trading date prior to the publication of the statement regarding a possible offer from Reabold (the "Relevant Date"); and.

· 6.1 per cent. to the volume weighted average price of 3.95 pence per Union Jack Share for the three months ended on the Relevant Date.

The share for share offer provides Union Jack Shareholders with the opportunity to participate in the future upside of the Enlarged Group through ownership of shares in a larger, more diversified and more liquid AIM-listed company.

The Offer is conditional, among other things, upon valid acceptances of the Offer being received which will result in Reabold holding Union Jack Shares carrying, in aggregate, not less than 75 per cent. of the voting rights of Union Jack (or such lesser percentage as Reabold may decide, provided that Reabold together with its wholly-owned subsidiaries shall hold or have acquired or agreed to acquire (whether pursuant to the Offer or otherwise), directly or indirectly, Union Jack Shares carrying in aggregate more than 50 per cent. of the voting rights then normally exercisable at a general meeting of Union Jack).

The Offer is extended to all issued Union Jack Shares and any further Union Jack Shares which are unconditionally allotted or issued and fully paid before the Offer closes.

If any dividend, distribution or other return of value is authorised, declared, made or paid in respect of Union Jack Shares on or after the date of this Announcement the Offer Value shall be reduced by the amount of any such dividend, distribution or other return of value. In such circumstances, Union Jack Shareholders shall be entitled to retain any such dividend, distribution, or other return of value declared, made or paid.

The Union Jack Shares will be acquired pursuant to the Offer fully paid and free from all liens, charges, equitable interests, encumbrances, rights of pre-emption and other third party rights or interests together with all rights attaching thereto including, without limitation, the right to receive all dividends and other distributions (if any) announced, declared, made or paid after the date of this Announcement.

The Offer will extend to all Union Jack Shares unconditionally allotted or issued and fully paid on the date of the Offer and any Union Jack Shares which are unconditionally allotted or issued and fully paid (including pursuant to the exercise of Union Jack Share Options) and any Treasury Shares unconditionally sold or transferred by Union Jack, in each case whilst the Offer remains open for acceptance or by such earlier date as Reabold may, subject to the Code, decide, not being earlier than the date on which the Offer becomes unconditional.

3. Background to and reasons for the Offer

On 5 June 2026, Reabold submitted a non-binding indicative proposal to the board of Union Jack regarding a possible all-share offer for the entire issued and to be issued share capital of Union Jack.

Following receipt of the proposal, the board of Union Jack engaged with Reabold and its advisers and granted Reabold access to a confirmatory due diligence process.

Discussions between the parties have continued in respect of the possible terms of a transaction. Reabold and its advisers have undertaken due diligence on Union Jack's assets, operations and prospects, including its interests in onshore UK production and development licences and its expanding US portfolio.

The Reabold Board has, following this process and after careful consideration of the strategic merits of a combination of the two businesses, determined that the proposed acquisition of Union Jack represents an attractive opportunity to create a larger, more diversified and better capitalised oil and gas investment company.

On 30 June 2026, the boards of Reabold and Union Jack reached agreement on the terms of a recommended all-share offer, pursuant to which Reabold will acquire the entire issued and to be issued ordinary share capital of Union Jack, to be implemented by way of a contractual offer under Part 28 of the CA 2006.

Reabold is well-funded for its upcoming work programme, including the West Newton recompletion, and has recently demonstrated continued access to capital through the successful raising of £4.16 million through the issue of equity at the prevailing market price. For Union Jack Shareholders, the Offer provides an opportunity to realise an immediate premium while also gaining increased exposure to the development upside of West Newton as well as the broader Reabold portfolio within a larger, better capitalised platform. The Enlarged Group is also expected to benefit from reduced corporate costs and improved capital efficiency, allowing a greater proportion of capital to be deployed directly into asset development and value creation.

Strategic rationale

The Reabold Board believes that the combination of Reabold and Union Jack has a strong strategic and industrial logic, creating a more substantial UK-focused oil and gas investment company with complementary asset bases and aligned strategic objectives.

Both companies are focused on the development and monetisation of onshore oil and gas assets, primarily in the UK, with exposure to appraisal and development opportunities that require disciplined capital allocation and technical expertise. The Enlarged Group is expected to benefit from enhanced scale, broader asset diversification and improved access to funding.

Portfolio and asset combination

Union Jack's producing and development assets, including its interests in Wressle, West Newton and Keddington in the UK and its footprint in US onshore production, are considered by Reabold to be complementary to Reabold's existing portfolio of investments in upstream energy assets.

The combination is expected to:

· consolidate overlapping interests in the key UK licence, West Newton, resulting in increased economic exposure and simplified asset ownership;

· provide exposure to near-term production and cash flow from Union Jack's producing assets; and

· enhance the Enlarged Group's ability to advance development and appraisal programmes across its portfolio.

Scale, capital and market positioning

The Reabold Board believes that the Enlarged Group will benefit from:

· increased scale and market presence as a combined AIM-listed oil and gas investment company;

· improved access to equity and debt capital to fund development activity; and

· a broader and more diversified asset base, reducing asset-specific and funding risk.

In the current oil and gas environment, which is increasingly characterised by consolidation and a focus on capital efficiency, the Reabold Board believes that greater scale is an important driver of long-term shareholder value.

Operational efficiencies and synergies

Reabold expects that the combination will generate operational and corporate efficiencies over time, including:

· optimisation of development plans across shared assets;

· reduction of corporate and administrative costs; and

· improved capital allocation across a broader portfolio of opportunities.

Value creation for shareholders

The Reabold Board believes the Offer provides Union Jack shareholders with the opportunity to participate in the future upside of the Enlarged Group through an all-share structure and Reabold shareholders with exposure to a wider portfolio of producing and development assets with enhanced near-term cash flow potential.

Overall, the Reabold Board believes that the Offer represents a compelling opportunity to accelerate the development of both companies' asset bases and to create a better capitalised and more competitive platform for growth in the onshore oil and gas sector.

4. Recommendation

The Union Jack Directors, who have been so advised by Gneiss as to the financial terms of the Offer, consider the terms of the Offer to be fair and reasonable. In providing its advice to the Union Jack Directors, Gneiss has taken into account the commercial assessments of the Union Jack Directors. Gneiss is providing independent financial advice to the Union Jack Directors for the purposes of Rule 3 of the Code.

In addition, having undertaken an extensive review of Union Jack's strategic and financing options, and having carefully considered the alternatives available, the board of Union Jack has concluded that no alternative proposal capable of providing the funding required to execute Union Jack's strategy is currently available on acceptable terms. 

In the absence of such funding or the Offer, the board of Union Jack is of the view that Union Jack will, in the short term, be unable to meet its licence commitments, which, in accordance with the licence terms, may result in the forfeiture of key assets within the Union Jack portfolio.

The board of Union Jack believes that the Offer provides the only financing option to prevent this outcome and is therefore of the view that the Offer is in the best interests of shareholders.

Given the foregoing, the board of Union Jack welcomes that the Acceptance Condition has been set at a level that requires Reabold to acquire or contract to acquire shares carrying only approximately 75 per cent. of the voting rights normally exercisable at a general meeting of Union Jack.

Accordingly, the Union Jack Board intend to recommend that the Union Jack Shareholders accept the Offer, as all of the Union Jack Directors who are interested in Union Jack Shares have irrevocably undertaken to do (or procure to be done) in respect of their own holdings (and those of their connected parties) of, in aggregate, 3,132,144 Union Jack Shares, representing, in aggregate, approximately 2.14 per cent. of the issued ordinary share capital of Union Jack as at the Latest Practicable Date. These undertakings will remain binding in the event of a competing offer being made.

5. Considerations for the recommendation

The Union Jack Directors believe that the combination of Union Jack and Reabold will create a strengthened onshore oil and gas company with a balanced portfolio of near-term production, appraisal and high-impact development opportunities. The Enlarged Group would benefit from enhanced scale, a simplified corporate structure, and an improved platform.

In addition, having undertaken an extensive review of Union Jack's strategic and financing options, and carefully considered the alternatives available, the board of Union Jack has concluded that no alternative proposal capable of providing the funding required on acceptable terms to execute Union Jack's strategy is currently available and therefore is of the view that the Offer is in the best interests of Union Jack Shareholders.

Specific other considerations for the recommendation of the Offer include:

Portfolio consolidation and enhanced exposure to core UK assets

· A combined portfolio centred on a number of high-quality UK onshore licences, including material interests in producing and near-production assets including Wressle and West Newton, providing increased exposure across a range of development stages.

· Greater alignment of interests across certain key licences where both companies currently hold positions, enabling more efficient decision-making, streamlined governance and accelerated development execution.

· A diversified portfolio spanning cash-generative production, appraisal upside and longer-term development opportunities, enhancing resilience across commodity price cycles.

Improved scale and funding flexibility

· The Enlarged Group is expected to benefit from increased market capitalisation and liquidity, positioning it as a more relevant and investable vehicle within the UK small-cap E&P sector.

· Enhanced financial flexibility, supported by a combined cash position, production revenues and reduced duplication of corporate overheads, enabling more efficient capital allocation across the portfolio.

· Greater capacity to access external funding, including both equity and debt markets, on more favourable terms, supporting the advancement of key development projects.

Acceleration of value realisation from core projects

· Increased working interests in key projects are expected to enhance exposure to production and development upside.

· A more coordinated strategy for progressing appraisal and development assets, with the aim of unlocking material contingent resource potential through technical de-risking and development planning.

Strategic and operational synergies

· A strong strategic fit between the two companies, with highly complementary asset bases, overlapping geographic focus and aligned operational priorities.

· Opportunities to realise cost synergies through the elimination of duplicated corporate functions and the rationalisation of administrative and public company costs.

Enhanced market positioning

· The creation of a larger, more diversified entity is expected to improve visibility with institutional investors, potentially increasing trading liquidity and broadening the shareholder base.

· A more compelling investment proposition, combining production cash flow with significant development and appraisal upside, positioning the Combined Group as a differentiated onshore E&P platform.

Attractive transaction terms

· The terms of the Offer provide Union Jack Shareholders with exposure to a broader and more diversified portfolio, together with the potential for enhanced long-term value creation through the Enlarged Group.

· The implied valuation of the Offer represents a premium of approximately 25.0 per cent. to Union Jack's closing share price of 3.35 pence on the Relevant Date with material upside potential through ownership of the Enlarged Group.

· In addition, having undertaken an extensive review of Union Jack's strategic and financing options, and carefully considered the alternatives available, the board of Union Jack has concluded that no alternative proposal capable of providing the funding required on acceptable terms to execute Union Jack's strategy is currently available and therefore is of the view that the Offer is in the best interests of shareholders.

6. Information about Reabold

Reabold is an investing company incorporated and domiciled in England and Wales, whose ordinary shares are admitted to trading on AIM, a market operated by the London Stock Exchange.

Reabold is focused on investing in and developing upstream oil and gas projects, with a particular emphasis on assets that offer near-term production potential and the opportunity to create value through active management, technical oversight and disciplined capital allocation. Its strategy is to acquire interests in undervalued or underdeveloped oil and gas assets, primarily in OECD jurisdictions, and to enhance value through appraisal, development and monetisation.

Portfolio and asset base

Reabold holds a diversified portfolio of exploration, appraisal and development-stage oil and gas assets, with interests principally in the United Kingdom, Italy, Romania and the United States.

· United Kingdom - Rathlin Energy (UK) Limited and PEDL 183

Reabold's principal asset is its interest in the West Newton gas development project, located onshore within the PEDL183 licence in East Yorkshire.

Reabold has an approximately 79.8 per cent. shareholding in Rathlin Energy (UK) Limited ("Rathlin"). Through this holding (together with its direct licence interest), Reabold has an economic interest of approximately 69.9 per cent. in the West Newton project and the wider PEDL183 licence area.

West Newton is considered by Reabold to be a potentially material onshore UK gas resource and represents a central element of its strategy to support domestic energy supply. The project is currently in the appraisal and development phase, with ongoing work programmes designed to de-risk the asset and progress it towards production.

· Italy - Beacon Energy plc

Reabold holds a 22.69 per cent. interest in Beacon Energy plc ("Beacon"), which has a 42.3 per cent. economic interest in the Colle Santo gas project in Abruzzo, Italy. Colle Santo is a material onshore gas development project, with estimated 2P reserves of approximately 65 Bcf, and is intended to be developed as one of the first small-scale LNG projects in Italy.

As part of the consideration for the sale of Reabold's interest in LNEnergy Limited to Beacon in October 2025, Reabold is entitled to receive up to €16 million through an earn-out mechanism, under which it will receive 25 per cent. of its pro rata share of net cash flows generated by the Colle Santo project once production commences.

Reabold, through its shareholding in Beacon and earn-out entitlement, retains a material indirect and economic interest in the Colle Santo project, while having no further funding obligations in respect of its development

· Romania - Danube Petroleum Limited

Reabold has a 50.8% equity position in Danube Petroleum Limited ("Danube"), with ASX listed ADX Energy Ltd ("ADX") holding the remaining 49.2% via its wholly owned subsidiary ADX Energy Panonia SRL ("Panonia"), the operator of the licence. Danube has a 100% interest in the Parta exploration and Iecea Mare production licence in Western Romania, which includes the IMIC-1 discovery and the IMIC-2 prospect.

On 24 October 2025, ADX announced that, despite repeated requests to extend the Parta licence, the Regulatory Authority had advised that the exploration phase 1 of the licence has expired and had issued Panonia with invoices totalling EUR 4.2 million for alleged expenditures relating to the unperformed exploration commitments applicable to Parta.

ADX, on behalf of Panonia, is formally disputing these invoices on the basis of having incurred significant costs to address the unforeseen challenges attributable to the work program, as well as due to the regulatory delays and access restrictions which have prevented Panonia from entirely fulfilling the work program, and denied Panonia the ability to benefit from the potential upside from making a discovery.

· United States - Daybreak Oil and Gas

Reabold has a 42% shareholding in Daybreak Oil and Gas Inc ("Daybreak"). Daybreak is an OTC-traded oil and gas company engaged in the exploration, development and production of onshore crude oil and natural gas, primarily in California.

On 3 June 2026, Reabold announced that it had entered into an exclusivity agreement with Zenith Energy plc granting it exclusivity to evaluate a potential acquisition of Reabold's shares in Daybreak.

· Other investments and monetisation track record

Reabold has historically built and realised value through its investment model, including the sale of its interest in the Victory gas project to Shell, generating material cash proceeds, and the ongoing monetisation of its Colle Santo exposure through the Beacon transaction.

Strategy and positioning

Reabold's portfolio is weighted towards gas-focused development assets, particularly in Europe, reflecting its strategic focus on energy security and domestic supply.

The portfolio comprises a mix of assets mainly in the late-stage appraisal and development part of the oil and gas project lifecycle, providing a balance of potential near-term cash flow and longer-term value creation.

The Reabold Board believes that its investment-led model, combined with active asset management and a focus on monetisation, positions Reabold to deliver shareholder value through the progression and crystallisation of its asset base.

Reabold is headquartered in London.

7. Information about Union Jack

Union Jack is an oil and gas company with a focus on onshore production, development, exploration and investment opportunities within the United Kingdom and the United States of America ("USA") hydrocarbon sector.

Union Jack currently has interests in multiple key licences within the East Midlands, Humber Basin and East Yorkshire in the United Kingdom and more recently has expanded into the USA by assembling a portfolio of development and exploration assets in Oklahoma, working in conjunction with its partner Reach Oil and Gas Inc. ("Reach").

Portfolio and asset base

United Kingdom

· Wressle Development PEDL180 and PEDL182

Union Jack has a 40% interest in the Wressle-1 discovery ("Wressle") located in North Lincolnshire, on the western margin of the Humber Basin and is one of the most productive conventional producing onshore oilfields in the UK.

Wressle has generated revenues in excess of US$24,000,000 net to Union Jack before taxes. To date, over 800,000 barrels gross of high-quality oil have been produced and sold from Wressle.

During the year ended 31 December 2025, Wressle produced on constrained flow an average of 297 barrels of oil per day ("bopd"), Union Jack net 119 bopd.

The Wressle project remains a high-value asset in Union Jack's portfolio with 2P reserves of over 2,300,000 barrels of oil equivalent gross to be extracted according to ERCE as stated within their Competent Persons Report.

The joint venture parties are awaiting regulatory approvals for planning and permit applications that will enable the next phase of field development to take place.

· West Newton Development PEDL183

Union Jack holds a 16.665% working interest in PEDL183, that incorporates the West Newton gas discoveries and is operated on behalf of the joint venture partners by Rathlin. As set out above, Reabold has an economic interest of approximately 69.9 per cent. in the West Newton project and the wider PEDL183 licence area.

PEDL183 is located onshore in the UK, north of the River Humber, encompassing the town of Beverley, East Yorkshire. The licence area is within the western sector of the Southern Zechstein Basin.

The West Newton drilling programmes have yielded substantial hydrocarbon discoveries within the Kirkham Abbey formation.

The North Sea Transition Authority ("NSTA") has approved a revised work programme, for PEDL183, which is subject to regulatory and other approvals, allowing progress in the most efficient manner.

Commercial gas production could be brought to market within months of a successful well test whilst additional activity is carried out on the further development of West Newton.

Union Jack is confident that West Newton will prove to be an important strategic asset to the UK as the country looks to secure domestic energy supply and affordable energy.

· Keddington Development PEDL005(R)

The producing Keddington oilfield, in which Union Jack has a 55% interest, is located along the highly prospective East Barkwith Ridge, an east-west structural high on the southern margin of the Humber Basin.

Following a major upgrade of site facilities and infrastructure during 2025, Keddington was brought back on-line in June 2025 and to date over 8,750 barrels of oil have been produced and sold.

A technical review by Reach (the operator) has confirmed that there remains an undrained oil resource located on the eastern side of the Keddington field. Planning consent for further drilling is already in place, presenting an opportunity to increase production via a development side-track from one of the existing wells.

To facilitate confirmation of the target definition and well design planning, re-processing of legacy 3D seismic data has been completed.

Modelling indicates that infill drilling is forecast to improve recovery from the Keddington field by between 113,000 to 183,000 barrels of oil, depending on the reservoir permeability and infill target.

The sub-surface location of a step-out well has been finalised and it is planned to drill the well, where planning consent is already granted, when the operator deems appropriate.

United States of America

Since commencing activities in the USA, Union Jack has:

• Acquired material ownership interests in numerous drilling, development and production projects in Oklahoma

• Formed a drilling partnership with Reach

• Built a quality, cash generating, Mineral Royalty portfolio in the Permian Basin, Bakken Shale and Eagle Ford Shale

• Received material cash flows from its operations

· Andrews 1-17 and Andrews 2-17 Discovery Wells Oklahoma - The Andrews Field

Union Jack holds a 45% interest in the producing Andrews Field ("Andrews"), located in Seminole County, Oklahoma, USA, on which two exploration wells were successfully drilled.

Andrews, comprising of the Andrews 1-17 and Andrews 2-17 discovery wells are predominantly gas producers with associated oil from the Hunton Limestone formation ("Hunton"), one of the main hydrocarbon reservoirs in Oklahoma.

Since the commencement of production, Andrews has produced and sold over 100,000,000 cubic feet of clean natural gas and approximately 10,000 barrels of high-quality oil with an average API of 45.5 degrees.

In-house assessment of gas reserves by the operator, Reach, is that over 1.2 billion cubic feet of recoverable gas remain in place with an estimated field life of approximately 20 years.

OPEX costs associated with Andrews are remarkably low, currently at approximately US$3,500 per month, translating into production costs of less than US$5 per barrel of oil equivalent and driving healthy operating netbacks.

· Moccasin 1-13 Discovery

The producing Moccasin 1-13 Discovery ("Moccasin"), in which Union Jack has a 45% interest, located in Pottawatomie County, Oklahoma was drilled in January 2025 to test a dip and fault closed structure west of the Wilzetta fault.

Moccasin encountered hydrocarbons in three zones, the 1st Wilcox, Bartlesville and Red Fork sands.

The 1st Wilcox sand was perforated and production established in February 2025. To date Moccasin has produced circa 23,000 barrels of good quality oil and is currently producing approximately 48 bopd.

The Red Fork and Bartlesville sands have good hydrocarbon shows from the geological sample log and the Computed Petrophysical Interpretation indicates hydrocarbon presence in both of these formations. The hydrocarbons are "behind pipe" and remain to be perforated at a later date.

Since completion of the 1st Wilcox sand, Union Jack has purchased the 3D seismic over the Moccasin prospect area. Preliminary evaluation indicates another potential structure is present and mapping of the seismic continues.

· Wilzetta Fault Play 

Union Jack signed a farm-in agreement with Reach to acquire a 75% interest in a high-impact well, Diana-1, planned to be drilled at a future date to test the Footwall Fold Prospect in the Wilzetta Fault play, a proven oil-producing location and in an area of associated interest.

The prolific Wilzetta Fault plays are the sites of numerous oilfields across Central Oklahoma. Typical wells drilled in the Wilzetta Fault can produce approximately 250 barrels of oil per day providing pay-back within three months.

The proposed Diana-1 well is intended to be drilled to a depth of 6,000 feet and the prospect integrity is supported by recently reprocessed 3D seismic data.

· Rogers Secondary Recovery Project

The Rogers enhanced oil recovery project is located approximately two kilometres from the Andrews Field and is planned to materially increase delivery from two legacy production wells. Union Jack has a 45% interest in this project.

Base-case secondary recovery volumes calculated by the operator, Reach, suggest that up to a further 124,000 barrels of oil can be recovered. The Union Jack Directors believe the project economics are attractive, indicating future gross revenues at prevailing oil and gas prices of approximately US$5.0 million with a remarkable IRR approaching 60%.

· Taylor 1-16 Well

The producing Taylor 1-16 well ("Taylor"), in which Union Jack has a 45% interest, encountered the Hunton, Misner and Cromwell Sand formations.

The Cromwell formation was subjected to a nitrogen foam treatment to enhance production. Following the application of this process, the Taylor well is now producing up to 15 bopd and permanent production facilities have been installed.

· Mineral Royalties

Union Jack holds six mineral royalty packages, all brokered by Union Jack's Oklahoma-based agent and adviser, Reach (the "Mineral Royalties").

The Mineral Royalties portfolio delivered returns in excess of 11.9% by contributing revenues of £89,819 in 2025 (£196,737 in 2024) based on a capitalised value of £751,834 at year end 2025 (£783,219 in 2024).

The general attractions of USA Mineral Royalties include:

• Exposure to active and productive basins and some of the largest operators in the USA;

• Monthly income with no development or operating costs;

• Ownership in perpetuity, with no forward liabilities or obligations;

• Royalties estimated to have a long economic life, in some cases more than 26 years and an IRR in excess of 11.9% during 2025.

The Mineral Royalties assembled to date are summarised below:

• Cronus Unit, containing a 25 well package in the Permian Basin, Midland County, Texas comprising of nine Chevron and 16 XTO (a subsidiary of Exxon) operated wells;

• COG Operating LLC (a subsidiary of ConocoPhillips) operated Powell Ranch Unit, consisting of 15 wells in the Permian Basin, Upton County, Texas comprising of seven horizontal and eight vertical wells;

• Occidental operated Palm Springs Unit, containing 10 horizontal wells in the Permian Basin, Howard County, Texas;

• Bakken Shale, a diversified 96 well interest package, located in Dunn, McKenzie and Williams Counties, North Dakota. Quality operators include Burlington Resources, Continental and Hess;

• Permian Basin, an 8 well producing unit, located in Howard and Borden Counties, Texas. Operated by Vital Energy Inc, a quoted, Permian Basin focused entity, based in Tulsa, Oklahoma

• Eagle Ford Shale, comprising of a 9 producing horizontal well package, located in DeWitt County, Texas, operated by ROCC Operating

The Mineral Royalties provide additional upside at no cost to Union Jack.

The operators associated with the Mineral Royalties are all major producers, ranking highly in the S&P Global (formerly Standard & Poor's), Fitch, and Moody credit ratings.

8. Irrevocable Undertakings

The Directors of Union Jack who currently beneficially hold or control Union Jack Shares have provided irrevocable undertakings to accept the Offer in respect of an additional 3,132,144 Union Jack Shares, representing approximately 2.14 per cent. of the issued ordinary share capital of Union Jack as at the Latest Practicable Date.

These irrevocable undertakings remain binding in the event a higher competing offer is made for Union Jack.

A condition of the Offer will be for Reabold to receive valid acceptances in respect of, and/or having otherwise acquired, Union Jack Shares which constitute not less than 75 per cent. of the voting rights relating to Union Jack's ordinary share capital, which would be satisfied by the receipt of valid acceptances of the Offer in respect of these irrevocable undertakings.

Further details of these irrevocable undertakings, including the circumstances in which they may lapse, are set out in Appendix III to this Announcement.

9. Reabold's intentions regarding Union Jack's Business, Management and Employees

Strategic plans for Union Jack

Following the Unconditional Date, Reabold intends to manage Union Jack and its interests as part of Reabold's existing portfolio in accordance with its existing investing policy as an AIM-quoted investing company.

Reabold views the licence interests and other assets held by Union Jack as being complementary to its existing portfolio, including its existing exposure to West Newton. The Reabold Board believes that the Offer represents a compelling strategic opportunity to enhance scale, diversify the Enlarged Group's portfolio and improve capital allocation flexibility.

Following the Unconditional Date, the Enlarged Group will seek to:

· add Union Jack's producing and development interests to Reabold's existing portfolio of direct and indirect interests in upstream oil and gas projects and assets;

· optimise capital deployment across the Enlarged Group's portfolio, prioritising near-term cash generative opportunities and value-accretive development projects; and

· leverage Reabold's technical, commercial and financial expertise to oversee, support and seek to maximise value from Union Jack's interests and assets.

Reabold intends that the Enlarged Group will continue to pursue Reabold's existing strategy of investing in and managing direct and indirect interests in upstream oil and gas opportunities, with an increased emphasis on production-led cash flows and disciplined portfolio management.

Board, management and employees of Union Jack

David Bramhill, Executive Chairman, and Joseph O'Farrell, Executive Director, are the only current employees of Union Jack (the "Executive Directors"). Otherwise, Union Jack operates through a combination of external consultants and service providers. It is intended that, following the Unconditional Date, Reabold will retain the benefit of these consultancy arrangements and service contracts to the extent necessary.

It is expected that, following the Unconditional Date, the employment of the Executive Directors will be terminated and that they will each resign from their directorships of Union Jack, along with Union Jack's non-executive director, Dr Zac Phillips. The Executive Directors have entered into conditional settlement agreements with Union Jack in respect of the expected termination of their employment as a result of the Offer, and will (subject to completion of the Offer) each receive a settlement payment amounting to £100,000 (net of tax), which is less than their respective contractual entitlements on termination. Dr Zac Phillips will receive payment in lieu of his contractual notice period.

Accordingly, it is intended that the Enlarged Group will operate under Reabold's existing board, management and governance framework, subject to such changes as Reabold considers appropriate following completion of the Offer.

Existing employment rights and pensions

Union Jack provided the Executive Directors access to a stakeholder pension scheme which did not include any employer contributions. Both the Executive Directors opted out of this scheme. Accordingly, Reabold has no intentions in respect of employer contributions to pension schemes, the accrual of benefits for any members, the admission of new members, or the establishment of any pension arrangements for Union Jack following the Unconditional Date.

Save as set out above in relation to board changes, Reabold does not intend to make any material changes to the management of Union Jack nor employment policy as a result of the Offer.

Management incentivisation arrangements

Reabold has not entered into, and has not had any discussions regarding, any new incentivisation arrangements with members of Union Jack's management in connection with the Offer prior to the Unconditional Date. Following the Unconditional Date, Reabold intends to review the incentivisation arrangements of the Enlarged Group in due course.

Headquarters, locations, branding, fixed assets and research and development

Following the completion of the Offer, Reabold intends to maintain its existing registered office in London which will become the registered office of the Enlarged Group.

Union Jack maintains a registered office in Bath, being the address of its Company Secretary. Union Jack does not operate from this address and does not have any permanent office address or fixed assets. Accordingly, no material changes are intended in respect of Union Jack's business locations or fixed assets, or to the headquarters or headquarters function of the Enlarged Group as a consequence of the Offer.

Following completion, it is intended that the Enlarged Group will operate under Reabold's existing name and branding. Owing to the nature of Union Jack's business, Union Jack does not have a research and development function and Reabold has no plans to establish such a function following the Unconditional Date.

Effect on Reabold's existing business

Other than as set out above, Reabold does not expect there to be any material impact on the strategic plans, management, employees, locations or headquarters functions of the existing Reabold group as a consequence of the Offer.

Trading facilities

Union Jack Shares are currently admitted to trading on AIM and the OTCID Basic Market. As set out in paragraph 14 below, on or shortly after the Unconditional Date, an application will be made to the London Stock Exchange for the cancellation of the admission to trading of Union Jack Shares on AIM shortly following the Unconditional Date and an application will be made to OTC Markets Group for the cancellation of the admission to trading of Union Jack Shares on the OTCID Basic Market. Following which, Union Jack is expected to be re-registered as a private limited company.

Post-offer undertakings

None of the statements in this paragraph 9 constitute "post-offer undertakings" for the purposes of Rule 19.5 of the Code.

10. Union Jack Share Options

The Offer will affect holders of Union Jack Share Options. Appropriate proposals will be made to the holders of such instruments in accordance with Rule 15 of the Code, and each grant of such Share Options shall be treated in accordance with the rules applicable to it. Further details of these arrangements will be communicated to the holders of Union Jack Share Options in due course.

The Offer extends to any Union Jack Shares which are unconditionally allotted or issued and fully paid (or credited as fully paid) on or before the date on which the Offer closes (or such earlier date as Reabold may, subject to the Takeover Code, decide) including any such shares allotted or issued pursuant to the exercise, release or other settlement of existing options, awards and any other rights granted under the Union Jack Share Options following the Offer becoming or being declared unconditional in all respects.

11. Disclosure of interests in relevant securities

As at the close of business on the Last Practicable Date, save for the irrevocable undertakings referred to in paragraph 8 of this Announcement, neither Reabold nor, so far as Reabold is aware, any person acting in concert with Reabold for the purposes of the Offer, has an interest in or right to subscribe for, or has any arrangement in relation to, relevant securities of Union Jack, or had any short position in relation to any relevant securities of Union Jack, whether conditional or absolute and whether in the money or otherwise, including any short position under a derivative, any agreement to sell or any delivery obligation or right to require another person to purchase or take delivery of relevant securities of Union Jack, or has borrowed or lent (including for these purposes, entering into any financial collateral arrangements of the kind referred to in Note 4 to Rule 4.6 of the Code) any relevant securities of Union Jack.

For these purposes, "arrangement" includes any indemnity or option arrangement, and any agreement or understanding, formal or informal, of whatever nature, relating to Union Jack Shares which may be an inducement to deal or refrain from dealing in such shares. In this paragraph, "relevant securities of Union Jack" means Union Jack Shares and securities convertible into, or rights to subscribe for, options (including trade options) in respect thereof and derivatives referenced thereto. Neither Reabold nor any person acting in concert with Union Jack has any Note 11 Arrangement.

12. Offer Related Arrangements

Confidentiality Agreement

Reabold and Union Jack entered into a confidentiality agreement dated 10 June 2026 ("Confidentiality Agreement") pursuant to which, amongst other things, Reabold gave undertakings to keep information relating to the Offer and Union Jack confidential and not disclose it to third parties, subject to certain permitted exceptions. The Confidentiality Agreement also contains customary non-solicitation and standstill provisions, in each case subject to customary carve-outs, which apply for a period of 6 months from the date of the Confidentiality Agreement. The obligations of Reabold pursuant to the Confidentiality Agreement shall expire on the earlier of (i) the date falling on 18-month anniversary of the date of the Confidentiality Agreement and (ii) completion of the Offer.

13. Conditions

The Offer will be subject to the Conditions and further terms set out in Appendix I to this Announcement. The Offer will lapse unless all of the Conditions have been fulfilled or, where permitted, waived or, where appropriate, have been determined by Reabold to be or remain satisfied, by midnight (London time) on the earlier of the Unconditional Date or the Long-stop Date (subject to the rules of the Code and where applicable, the consent of the Panel). In particular, the following Conditions shall apply:

Valid acceptances of the Offer having been received (and not, where permitted, withdrawn) by no later than 1.00 p.m. (London time) on the Unconditional Date (or such other time(s) and/or date(s) as Reabold may specify, with the consent of the Panel and in accordance with the Code) in respect of not less than 75 per cent. of the Union Jack Shares to which the Offer relates and of the voting rights attached to those shares (or such lesser percentage as Reabold may decide) provided that Reabold together with its wholly-owned subsidiaries shall hold or have acquired or agreed to acquire (whether pursuant to the Offer or otherwise), directly or indirectly, Union Jack Shares carrying in aggregate more than 50 per cent. of the voting rights then normally exercisable at a general meeting of Union Jack including (the "Acceptance Condition").

For the purposes of the Acceptance Condition: 

a) Union Jack Shares which have been unconditionally allotted but not issued before the Offer becomes or is declared Unconditional, whether pursuant to the exercise of any outstanding subscription or conversion rights or otherwise, shall be deemed to carry the voting rights they will carry on issue;

b) the expression "Union Jack Shares to which the Offer relates" shall be construed in accordance with Chapter 3 of Part 28 of the CA 2006;

c) valid acceptances shall be deemed to have been received in respect of Union Jack Shares which are treated for the purposes of Part 28 of the CA 2006 as having been acquired or contracted to be acquired by Reabold by virtue of acceptances of the Offer; and

d) Union Jack Shares (if any) that cease to be held in treasury before the Offer becomes, or is declared, unconditional as to acceptances are Union Jack Shares to which the Offer relate.

Unless the Panel consents otherwise, the Acceptance Condition shall only be capable of being satisfied when all other Conditions set out in Part A of Appendix I have been satisfied or, if permitted, waived.

NSTA Condition

The receipt of the written unconditional consent (or consent provided in any form which is at that time customary) of the North Sea Transition Authority (the "NSTA"), pursuant to the terms of any licence held by Union Jack relating to petroleum situated in Great Britain, its territorial sea or the UK Continental Shelf, in respect of the proposed change of control of Union Jack pursuant to the Offer.

Admission Condition

Either:

· Admission of the New Reabold Shares to trading on AIM; or

· if Reabold so determines (and subject to the consent of the Panel), the London Stock Exchange having acknowledged to Reabold or its agent (and such acknowledgement not having been withdrawn) that the New Reabold Shares will be admitted to trading on AIM.

Reabold Shareholder Approval

The Reabold Shareholders passing the Reabold Shareholder Resolution at the Reabold General Meeting.

14. Cancellation of trading, compulsory acquisition and delisting

It is intended that an application will be made to the London Stock Exchange to cancel the admission to trading in Union Jack Shares on AIM, with such cancellation expected to take effect shortly after completion of the Offer. If such application is made, it is expected that cancellation of admission to trading on AIM will take place no earlier than 20 Business Days after the date on which Reabold has, by virtue of its shareholding and acceptance of the Offer, acquired, or agreed to acquire, 75 per cent. of the voting rights attaching to the Union Jack Shares. Reabold will procure that Union Jack makes a regulatory announcement when the necessary 75 per cent. threshold has been reached confirming that the notice period has commenced and the anticipated date of cancellation and withdrawal.

If, following the Offer becoming or being declared unconditional, Reabold has not acquired or agreed to acquire at least 75 per cent. of the issued share capital of Union Jack, Reabold will not, by virtue of its own shareholding be in a position to procure the cancellation of admission to trading on AIM of Union Jack Shares and the cancellation would need to be approved at a meeting of Union Jack Shareholders.

It is also proposed that, following Completion and after the cancellation of its shares from trading, Union Jack will be re-registered as a private limited company under the relevant provisions of the CA 2006. Cancellation of admission to trading on AIM will significantly reduce the liquidity and marketability of all Union Jack Shares not assented to the Offer at that time.

For so long as Union Jack Shares remain admitted to trading on AIM, Reabold intends that Union Jack maintains a board of directors that complies with the relevant rules of the exchange.

If the Offer becomes or is declared as unconditional and Reabold receives valid acceptances in respect of Union Jack Shares which, together with the Union Jack Shares acquired, or agreed to be acquired, before or during the Offer by Reabold, represent not less than 75 per cent. of the voting rights attaching to the Union Jack Shares, Reabold expects to seek to re-register Union Jack as a private company under the relevant provisions of the CA 2006.

If Reabold receives acceptances under the Offer in respect of, or otherwise acquires, not less than 90 per cent. of Union Jack Shares to which the Offer relates and not less than 90 per cent. of the voting rights carried by those shares, Reabold intends to exercise its rights pursuant to the provisions of sections 974 to 991 (inclusive) of the CA 2006 to acquire compulsorily the remaining Union Jack Shares in respect of which the Offer has not been accepted on the same terms as the Offer.

15. Issue and Admission of New Reabold Shares

The Reabold Directors do not currently have authority to issue and allot the New Reabold Shares in accordance with section 551 of the CA 2006 and, accordingly, the approval of Reabold Shareholders to the issue of the New Reabold Shares is required. The Offer is therefore conditional upon, amongst other things, the Reabold Shareholder Resolution being passed by the Reabold Shareholders at the Reabold General Meeting which will be convened in due course.

The New Reabold Shares will be issued in registered form and will be capable of being held in certificated and uncertificated form. Following the Offer becoming or being declared unconditional, the New Reabold Shares will be issued as fully paid and will rank equally in all respects with the Reabold Shares in issue at the time the New Reabold Shares are issued pursuant to the Offer, including in relation to the right to receive notice of, and to attend and vote at, general meetings of Reabold, and the right to receive and retain any dividends and/or other distributions declared, made or paid, or any other return of capital (whether by reduction of share capital or share premium account or otherwise) made, by Reabold in respect of the Reabold Shares with a record date falling after the Offer becoming or being declared unconditional and to participate in the assets of Reabold upon a winding-up of Reabold.

Irrespective of the date on which the Offer becomes or is declared unconditional falls, Union Jack Shareholders will not be entitled to receive any dividend declared, made or paid by Reabold for the benefit of the Reabold Shareholders by reference to a record date falling on or before the date on which the Offer becomes or is declared unconditional.

Application will be made to the London Stock Exchange for the New Reabold Shares to be admitted to trading on AIM. It is expected that Admission will become effective and that dealings for normal settlement in respect of the New Reabold Shares issued to Accepting Shareholders who submit valid acceptances on or before the date the Offer becomes or is declared unconditional, will commence on AIM within 14 days of such a date. It is expected that Admission will become effective and that dealings for normal settlement in respect of the New Reabold Shares issued to Accepting Shareholders who submit valid acceptances after the date the Offer becomes or is declared unconditional will commence on AIM within 14 days of submitting such acceptance.

No application has been made or is currently intended to be made by Reabold for the New Reabold Shares to be admitted to listing or trading on any other exchange.

This Announcement has been prepared for the purposes of complying with English law, the Market Abuse Regulation, the Disclosure Guidance and Transparency Rules, the AIM Rules and the rules of the London Stock Exchange and the Code, 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 the United Kingdom.

The release, publication or distribution of this Announcement in or into certain jurisdictions other than the United Kingdom may be restricted by law and therefore any persons who are subject to the laws of any jurisdiction other than the United Kingdom should inform themselves about, and observe, any applicable requirements.

To the fullest extent permitted by applicable law, the companies and persons involved in the Offer disclaim any responsibility or liability for the violation of such restrictions by any person.

Copies of this Announcement and formal documentation relating to the Offer shall not be, and must not be, mailed or otherwise forwarded, distributed or sent in, into or from any Restricted Jurisdiction or any jurisdiction where to do so would violate the laws of that 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.

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, Reabold or any member of the Wider Reabold Group 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, any member of the Wider Reabold Group 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, any member of the Wider Reabold Group'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", "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 or any member of the Wider Reabold Group, 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 any member of the Wider Reabold Group, or any of their respective associates, directors, officers, employees or advisers, are expressly qualified in their entirety by the cautionary statement above.

Reabold and the Wider Reabold Group expressly disclaim 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.

No profit forecasts or estimates

No statement in this Announcement is intended or shall be deemed to be a profit forecast, estimate or projection of the future financial performance of Reabold or Union Jack for any period except as otherwise stated and no statement in this Announcement should be interpreted to mean that cashflow from operations, earnings or earnings per share or income of those persons (where relevant) for the current or future financial years would necessarily match or exceed the historical published cashflow from operations, earnings or earnings per share or income of those persons (where relevant).

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).

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.

This will be judged by the Panel by reference to the facts of each case at the time that the relevant circumstances arise.
