Zenith Energy Ltd. (LSE: ZEN; OSE: ZENA; XSAT: ZENA SDR), the listed international energy production and development company,is pleased to announce that it has invested a further £259,000 in Reveille Resources PLC (“Reveille”), a Uranium-focused natural resources investment company, whose shares are expected to admit to trading on the Aquis Growth Market (the “Aquis”) with effect from 7 July 2026 (“Admission”).The Company will be issued 5,180,000 ordinary shares of 1 pence each in Reveille (“Reveille Shares”), at a price of 5 pence per share, conditional on Admission.

The Company has completed the sale of Futuro Energetico Italiano Srl (“FEI”), a special purpose vehicle established to hold and develop theVal VedelloandNovazzauranium licence applications, to Reveille for a nominal consideration.Zenith will be issued 7,000,000 Reveille Shares at a price of 5 pence per share on Admission, to reflect Zenith’s accrued costs in progressing FEI’s Val Vedello and Novazzauranium exploration applications (together, the “Lombardy Project”) to this stage of £350,000 (the “FEI Shares”).

This new investment, together with the Company's previous investment of£200,000, announced on 30 April 2026, and the issue of the FEI Shares, will result in Zenith becoming Reveille's largest shareholder, holding20,180,000 Reveille Shares, representing approximately25.26%of Reveille's issued share capital on Admission.

These warrants are subject to the terms of the Reveille IPO and are exercisable only in respect of the underlying shares that continue to be held by Zenith throughout the loyalty period.

Andrea Cattaneo, Chief Executive Officer of Zenith, commented:

“We are delighted to become the largest shareholder in Reveille upon its admission to the Aquis Growth Market. The spin-out of the Lombardy Project has always represented, in our view, the most effective way for Zenith shareholders to realise the value of these uranium assets within a dedicated exploration company focused exclusively on advancing them.

Reveille is now well positioned to progress the Novazza and Val Vedello exploration licence applications and, subject to the necessary regulatory approvals, advance towards delineating a modern mineral resource at one of Europe's most significant historical uranium districts.

We are pleased that Reveille's IPO has attracted the support of high-quality institutional investors, includingYA II PN, Ltd., an investment fund managed by Yorkville Advisors, a global investment manager with approximately US$1 billion of assets under management, alongside a number of experienced strategic investors who share our long-term vision for the Company. This provides strong validation of both the quality of the Lombardy Project and Reveille's strategy.

While Reveille is at an earlier stage of development, a comparative review of listed uranium companies underscores its compelling potential value proposition. With approximately 87,000 metres of historical drilling, 17 kilometres of underground development and historical uranium grades that compare favourably with several listed European uranium projects, including Berkeley Energia's Salamanca Project, we believe Reveille has the foundations to become one of Europe's leading uranium exploration companies as it successfully advances through the regulatory approval process and commences resource definition activities.

As Reveille's largest shareholder, with a 25.26% interest on Admission, Zenith is strongly aligned with the Company's future success and stands to benefit alongside all shareholders as Reveille executes its exploration strategy and seeks to unlock the significant long-term value of the Lombardy Project.”
