Zephyr Energy plc

("Zephyr" or the "Company")

Result of oversubscribed Bookbuild

and

Posting of notice of General Meeting

£10.5 million fundraise comprising a £9.8 million Placing and £0.7 million proposed Director Subscription

On 24 June 2025 the Company announced a proposed equity fundraising by way of an accelerated bookbuild (the "Fundraising Announcement"). The Board of Zephyr is pleased to announce that the Bookbuild has concluded and that it has conditionally raised gross proceeds of approximately £9.8 million at the Issue Price of 3.0 pence through the Placing of 326,666,667 Placing Shares to new and existing investors.

In addition, certain Directors, management and their affiliates intend to subscribe for 23,333,333 new Ordinary Shares at the Issue Price to raise a further £0.7 million for the Company after publication of the Company's audited results for the year ended 31 December 2024 by 30 June 2025, subject to the passing of the Resolutions.

The Placing was undertaken on the back of three key recent catalysts for the Company:

1. The Company delivered a highly successful production test on the State 36-2R well. The test achieved a notable, choked-back peak flow rate of 2,848 boe per day with no material drop in bottom hole pressure, and without the use of any fracture stimulation. Detailed test results indicate that the one-mile well's productivity will rank in the top 6% of all gas wells across the United States' 'Lower 48'. The well also demonstrated elevated liquid yields, and economic estimates appear to be competitive with longer lateral wells in core U.S. basins. Additional management analysis suggests that future, two-mile laterals on the Paradox project will have an estimated P50 individual well performance of 3.6 million boe per well and internal rates of return in excess of 280% (based on 29 May 2025 prices), significantly higher figures than exist today in core U.S. basins;

2. A US$100 million commitment from a major U.S.-based oil sector investor (the 'Investor') to accelerate growth through the drilling activity in Zephyr's Williston Basin non-operated asset portfolio. Pairing Zephyr's proven track record and deep regional expertise with the Investor's financial strength, the partnership is designed to increase consolidated cash flow rapidly and deliver attractive returns for all stakeholders; and

3. A proposed accretive, off-market acquisition that will add an initial 400 boepd net to Zephyr and 600,000 boe of proved developed producing (PDP) reserves to the portfolio. In addition, the Proposed Acquisition offers attractive near-term drilling upside potential suitable for the Investor and accretive to Zephyr.

Colin Harrington, Chief Executive of Zephyr, said: "I am delighted to announce the results of the oversubscribed Placing and believe that the Company has now passed an exciting inflection point in its growth and development trajectory.

"Net proceeds from the fundraise will generate immediate accretive production while also providing a path to first cash flow at the Paradox project. The result, following the highly successful State 36-2R well drilling and production testing operations, puts Zephyr in a position of real strength as we move to formalise dialogue with potential Paradox project infrastructure and industry partners. Further, it comes at a time when we believe we have "cracked the code" for a highly commercial future development of the Paradox project.

"It is anticipated that there will be considerable news flow as we progress through this exciting period. Updates are expected to include an updated independent Competent Person's Report ("CPR") on the Paradox project, deployment of initial funds from our strategic partnership, updates regarding discussions with industry and financial partners related to the acceleration of future development of the Paradox project, and the finalisation of infrastructure to enable us to secure sustainable production from our Paradox project wells.

"It should be noted that the Company's primary goal is to deliver production and returns from the Paradox project as quickly as possible. In addition to ongoing discussions with local pipeline and gas processing infrastructure partners, the Company has been approached by multiple parties, including compressed natural gas service companies and data centre / cryptocurrency mining operators, expressing an interest in securing direct, near-term offtake agreements for gas produced by the project. The Company first considered these early production concepts in 2022 and, cognisant of today's backdrop, has seen significant renewed interest from third parties related to this approach. These gas sales alternatives would not require any CAPEX contribution from Zephyr, but could provide for rapid deployment of a near-term gas sales solution - albeit for a portion of gas produced with the remainder ultimately sold via pipeline. Should a data centre / cryptocurrency mining venture come to fruition, the Board would consider the merits of the Company being paid in, and keeping in treasury, Bitcoin and, potentially, other mainstream cryptocurrencies.

"In summary, we are ready to capitalise on the recent progress made across our asset portfolio, and, as always, our Company's management and Board remains fully aligned with our shareholders. To date, management and affiliates have purchased circa 10% of the Company's issued share capital, and it is our intention to have meaningful participation in the fundraising. In light of recent catalysts and particularly given the excellent progress made delivering top-tier well results, management believes that Zephyr offers substantial future upside. We look forward to participating in this growth alongside all other shareholders.

"I would like to thank our adviser team for the successful execution of the Placing in challenging market conditions, and I speak for the entire Zephyr team in welcoming our new shareholders on board."

Notice of General Meeting and admission to AIM

Due to the limited existing share authorities available to issue new Ordinary Shares, the Placing will be conducted in two tranches, as follows:

· the First Placing: a placing of the 175,071,902 First Placing Shares at the Issue Price to be issued pursuant to the Company's existing authorities to issue and allot equity securities on a non-pre-emptive basis, granted at the annual general meeting of the Company on 31 July 2024, to raise approximately £5.3 million gross; and

· the Second Placing: a conditional placing of 151,594,765 Second Placing Shares at the Issue Price to be issued conditional on the passing of the Resolutions at the General Meeting to raise approximately £4.5 million gross.

The First Placing is conditional upon, inter alia, First Admission becoming effective on or around 27 June 2025 or such later time and/or date as the Bookrunners and the Company may otherwise agree (being in any event no later than 8.00 a.m. on 11 July 2025). Application has been made to London Stock Exchange for First Admission to occur on or around 27 June 2025.

The Second Placing is conditional upon, inter alia, the passing of the Resolutions to be proposed at the General Meeting to be held at the offices of Haynes Boone, 1 New Fetter Lane London, EC4A 1AN, United Kingdom at 10.00 a.m. on 14 July 2025 and Second Admission becoming effective on or around 15 July 2025.

A circular containing further details of the Placing and the notice of General Meeting is expected to be despatched to Shareholders later today. A copy of the Circular will be available on the Company's website later today at https://www.zephyrplc.com/.

Application will be made to London Stock Exchange for admission of the Second Placing Shares to trading on AIM ("Second Admission"), subject to, amongst other things, completion of the First Placing and the passing of the Resolutions. Second Admission is expected to occur on or around 15 July 2025 or such later time and/or date as the Bookrunners and the Company may agree (being in any event no later than 8.00 a.m. on 29 July 2025).

Change to significant shareholdings in the Company

As a result of the issue of the First Placing Shares, the shareholding of Origin Creek Energy LLC ("OCE") will be diluted on First Admission to approximately 8.25 per cent. (the number of Ordinary Shares that OCE holds will remain the same at 158,954,546). Rick Grant, the Chairman of Zephyr, and Colin Harrington, the Chief Executive Officer of Zephyr, are both shareholders and directors of OCE, and Colin Harrington is indirectly the controlling shareholder of OCE. Colin Harrington also has an interest in a further 1,453,936 Ordinary Shares and therefore his total interest in the Company including OCE will also be diluted on First Admission to approximately 8.33 per cent. (the number of Ordinary Shares that he holds in total will remain the same at 160,408,482).

Colin Harington intends to take part in the Director Subscription, which is expected to complete alongside the Second Placing subject to the passing of the Resolutions. A further announcement confirming the final details of the Director Subscription will be made following the announcement of the Results.

Total voting rights

Immediately following First Admission, the Company will have 1,925,790,922 ordinary shares of 0.1p each in issue, each with one voting right. There are no shares held in treasury. Therefore, the Company's total number of ordinary shares in issue and voting rights will be 1,925,790,922 and this figure may be used by shareholders from First Admission as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.

Unless otherwise defined, definitions contained in this Announcement have the same meaning as set out in the Fundraising Announcement.
