Union Jack Oil plc

("Union Jack" or the "Company")

Placing and Subscription of £2 million to fund growth

Union Jack Oil plc (AIM: UJO), a UK and USA focused onshore hydrocarbon production, development and exploration company, is pleased to announce that it has raised gross proceeds of £2 million (before expenses) through a successful placing (the "Placing") and subscription (the "Subscription") of an  aggregate of 40,000,000 new ordinary shares of 5 pence each in the Company ("New Ordinary Shares"), (the "Fundraise") at a price of 5 pence per New Ordinary Share (the "Issue Price").

It is proposed that each Placing and Subscription share will have one warrant attached, exercisable at 8 pence for a period of 2 years, representing a total of 40,000,000 warrants (the "Fundraise Warrants"). The New Ordinary Shares issued pursuant to the Placing and Subscription have been issued utilising the Company's existing authorities. The issue of the Fundraise Warrants will be subject to shareholder approval at a General Meeting, details of which will be notified in the coming days.

SP Angel Corporate Finance LLP ("SP Angel") and Zeus Capital Limited ("Zeus") acted as Joint Brokers in relation to the Placing (together "Joint Brokers").

Successful Strategic Entry into the USA

Over the past 12 months, following the Company's successful strategic entry into the USA in pursuit of near-term growth opportunities, Union Jack has delivered four back-to-back discoveries, established oil and gas production and sales and built a high-return Mineral Royalty portfolio.

Following the success of the recently drilled Mocassin-1 well, this play type is replicated in a number of other target wells that have been identified by the Company and its strategic Joint Venture and drilling partner, Reach Oil and Gas Company Inc. ("Operator").

The H2 2025 drilling programme has already commenced in Oklahoma and is focused on a three well, high-impact drilling programme that offers various primary and secondary stacked pay opportunities, expected to generate substantial news over the next six-month period and beyond.

Use of Proceeds

The Company will use the net proceeds of the Fundraise to fund continued success in the USA.

This success will be driven through the execution of a high-impact three well drilling programme in Oklahoma at a cost of circa US$3,000,000 that represents material value-creation opportunities as indicated by the combination of the size of the estimated recoverable resource, NPV10% pre-tax values at a US$65 oil price on success ("NPV10") with high estimates of the chance of success ("COS") of finding moveable hydrocarbons as estimated by the Operator, combined with a material working interest level held by Union Jack ("WI"):

o    "Sark" Central Oklahoma (60% WI) - has an estimated recoverable resource of 1,440,000 barrels of oil gross, COS of 65% and NPV10% circa US$19,900,000 net (see further details in the RNS dated 9 July 2025)

o    "Crossroads" Southern Oklahoma (43% WI) - has an estimated recoverable resource of 1,670,000 barrels of oil gross, COS of 40% and NPV10% of circa US$11,600,000 net

o    "Wolverine-1" Central Oklahoma (30% WI) - has an estimated recoverable resource of circa 1,310,000 barrels of oil, COS of 80% and NPV10% circa US$7,500,000 net

The three well programme has a potential aggregate NPV10% of circa US$39,000,000 net.

During Q2 2025, Union Jack averaged production from the USA and the UK of circa 175 boepd net and remains profitable.

David Bramhill, Executive Chairman of Union Jack, commented: "The Board would like to thank those new investors and shareholders who have participated in the Fundraise that will help deliver further growth for the Company.

"In just over 15 months, the Company, which remains debt free, has drilled four consecutive discoveries and compiled a portfolio of what we believe to be dynamic projects, forming the foundations of a valuable commercial business in the USA, complementing our profitable revenues from Wressle and Keddington in the UK.

"The recent success at Moccasin has been a major catalyst and Union Jack now has a fully-funded drilling and development programme in Oklahoma. We have commenced our high-impact three well drilling campaign that will deliver sustained news flow over the next six months and beyond in support of our stated growth strategy that, on success, will be financially transformative."

Further details on the Placing

The Placing comprises the issue of 32,200,000 New Ordinary Shares (the "Placing Shares") at the Issue Price to conditionally raise approximately £1.61 million before expenses for the Company.

The Company and the Joint Brokers have entered into a placing agreement (the "Placing Agreement"). Pursuant to the terms of the Placing Agreement, the Joint Brokers, as agents for the Company, have conditionally agreed to use their reasonable endeavours to procure subscribers for the Placing Shares. The Joint Brokers have conditionally placed the Placing Shares with certain institutional and other investors at the Issue Price.

Further details on the Subscription

The Subscription comprises the issue of an aggregate of 7,800,000 New Ordinary Shares (the "Subscription Shares") at the Issue Price to conditionally raise proceeds of approximately £390,000 before expenses for the Company.

Further details on the Fundraise

Both the Placing Shares and the Subscription Shares will rank pari passu with the Company's existing Ordinary Shares. The New Ordinary Shares issued pursuant to the Fundraise will represent approximately 27 per cent. of the enlarged share capital of the Company (as enlarged by the Fundraise, excluding shares held in treasury).

Related Party Transactions

David Bramhill, Joseph O'Farrell and Craig Howie ("Directors"), the Company's Executive Chairman, Executive Director and Non-Executive Director, respectively, and Matt Small, Company Secretary (Non-Board PDMR), have subscribed for an aggregate amount of £190,000 in the Fundraise as follows:

As Directors of the Company, David Bramhill, Joseph O'Farrell and Craig Howie are deemed to be related parties of the Company under the AIM Rules for Companies (the "AIM Rules") and therefore their participation in the Fundraise is classified as a related party transaction. The independent director of the Company, being Graham Bull, a Non-Executive Director of the Company, having consulted with SP Angel, the Company's Nominated Adviser, considers that the terms of the Directors' participation are fair and reasonable in-so-far as the Company's shareholders are concerned.

Application for Admission

Completion of the Fundraise is conditional upon admission of the New Ordinary Shares to trading on AIM ("Admission").

Application has been made to the London Stock Exchange for the New Ordinary Shares to be admitted to trading on AIM and it is expected that Admission will take place and that trading will commence on or around 8:00 a.m. on 29 July 2025. The New Ordinary Shares will rank pari passu in all respects with the existing ordinary shares.

Notice of General Meeting

In order to issue the Fundraise Warrants, the Company is preparing a Notice of General Meeting (the "Notice") to seek authority to disapply pre-emption rights of the Fundraise Warrants. The General Meeting date will be communicated to shareholders in the coming days and a further announcement will be made when the Notice has been sent to shareholders.

Total Voting Rights

Following Admission, the Company's share capital will comprise 152,865,896 Ordinary Shares. The Company holds 6,300,000 shares in Treasury, consequently the total voting rights will comprise 146,565,896 Ordinary Shares which is the figure which may be used by shareholders as the denominator for the calculation 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 Financial Conduct Authority's Disclosure and Transparency Rules.
