Acquisition of 5 MWp solar development projects

Zenith Energy Ltd. (LSE: ZEN; OSE: ZENA; XSAT: ZENA SDR), is pleased to announce the acquisition of two solar development projects, both situated in the Province of Puglia in Italy, of 2.5 MWp each (collectively, the “Puglia Acquisitions”).

Highlights

• Two solar development projects in Puglia, each with a capacity of 2.5 MWp: a 2-hectare photovoltaic plant and a 5-hectare agrivoltaic project, both located in areas designated for solar PV and agrivoltaic development. • Classified as being at the Development Stage.

• Payment will be made upon securing all required permits and achieving Ready-to-Build status at the conclusion of the development process.

• The land has been acquired at an average price of approximately €70,000 per hectare.

Solar Development Strategy

Following completion of the Puglia Acquisitions, Zenith's solar development pipeline has increased to a total of 183.5 MWp, representing a further expansion from the 173.5 MWp reported in the Company's most recent independent valuation as of March 31, 2026, which assigned a total value of EUR 54.7 million to the portfolio.

The expansion of the pipeline is expected to support further value creation as projects advance through permitting, Ready-to-Build, and construction stages. The Company remains focused on increasing the scale and quality of its portfolio while progressing assets towards monetisation and production. Andrea Cattaneo, Chief Executive Officer, commented: “The Puglia acquisitions, with a combined capacity of 5 MWp, increase Zenith’s solar development pipeline to 183.5 MWp and further strengthen our presence in the Puglia market.

We are now approaching our target of 200 MWp and are excited to begin construction of our first site in July 2026. At the same time, we are advancing other projects towards the Ready-to-Build stage and exploring the divestment of selected assets on potentially highly advantageous terms to support further expansion.”
