Business Growth Update and Acceleration Capital Funding

London, UK - Quantum Data Energy PLC (LSE: MAST) is pleased to announce that it has made significant progress to grow its portfolio of flexible generation power assets and megawatts ("MW") in production as it progresses toward its initial target of 300 MW. In particular, QDE is near completing financial close and commencing with construction of its Bordesley 5 MW flexible generation power project as recently announced in the Company's RNS announcement dated 3 February 2026.

As a result of the progress made and to fund QDE's capital requirements for the abovementioned project capex, an acceleration capital funding (the "Acceleration Capital") has been undertaken to support the expeditious completion. QDE has existing sufficient cash reserves to support the Company's working capital requirements, and therefore the Acceleration Capital use of proceeds is solely intended to provide capital to increase QDE's MWs in production.

The Acceleration Capital raises £1,165,000 gross via the issue of 46,600,000 new ordinary shares at an issue price of 2.5p per new ordinary share ("Placing Shares"). The Acceleration Capital has been facilitated by the Company's sole corporate broker, Fortified Securities.

Pieter Krügel, CEO at Quantum Data Energy PLC, said: "We are excited about the ongoing progress that we are making as we continue to build our portfolio of flexgen assets to our initial target of 300 MW and beyond. The Acceleration Capital has been undertaken solely to support the expeditious completion of an immediate growth opportunity that will make a meaningful contribution to QDE's portfolio of MWs in production. We are also working on a number of additional near term growth opportunities and look forward to updating the market with further updates in due course."
