Commencement of On-Site Power Generation

Issue of Warrants

Sterling Digital plc (AQSE: ASIC), a company established to develop low-energy-cost digital asset mining operations in the United States, is pleased to announce the successful commencement of on-site electricity generation at its West Texas site.

Following the installation of the equipment at the West Texas site announced on 12 June 2026, the Company's two 2 MW Caterpillar natural gas generators were started over the weekend and are now running as part of the commissioning programme. Power is generated from the offtake of underutilised, economically stranded natural gas in the WAHA pipeline in West Texas, secured under a five-year Gas Purchase Agreement, announced on 8 June 2026, and converted to electricity using the Company's proprietary energy optimisation infrastructure.

The generators have completed initial start-up and are undergoing fine-tuning and control-system calibration to optimise their performance, reliability and fuel efficiency prior to connection of the Company's ASIC mining servers. This includes verification of fuel, cooling, lubrication and electrical systems, calibration of engine controls and protective relays, and load testing to optimise combustion, voltage, frequency and load stability.

Once commissioning is complete, each generator will deliver approximately 1.6 MW net power, together powering 420 ASIC mining servers, representing approximately 193,500 terahashes per second (TH/s) of computing capacity.

Following validation of the power generation systems, the miners will be connected and brought online in controlled stages, with the objective of maximising system stability, operating efficiency and uptime from the outset.

Stefan Michaelides, CEO of Sterling Digital, commented:

"This is an important operational milestone for Sterling. For the first time, we are generating our own electricity in West Texas, utilising ultra low-cost surplus natural gas and turning months of planning, procurement and engineering into operating energy infrastructure.

Our site team and contractors have worked exceptionally hard to deliver this progress in demanding West Texas conditions.

With the generators live, our focus now shifts to final optimisation and the careful integration of the mining fleet.

Margins in Bitcoin mining are won on the cost of energy. Sterling's low-cost energy solution is laying the foundation for industry-leading profitability."

Issue of Warrants

Further to the above, the Company announces that it has issued 501,000 warrants over ordinary shares in the Company to a contractor in partial lieu of payment, at the contractor's request (the "Warrants"). The Warrants have an exercise price of 6 pence per ordinary share, vest immediately on grant and expire five years from the date of issue.

The Directors of the Company accept responsibility for the contents of this announcement.

About Sterling Digital plc

Sterling Digital plc (AQSE: ASIC) is developing low-energy-cost Bitcoin mining operations in the United States, using modular infrastructure and gas-to-energy generation to convert underutilised energy into productive compute.

The Company's initial focus is on West Texas which benefits from significant energy resources, established infrastructure, and constrained gas markets, creating an opportunity to convert underutilised gas into productive computing power.

Sterling has entered into a five-year gas purchase agreement for natural gas supply, including surface-use rights, in Martin County, West Texas. The agreement secures access to up to 6,500 MMBtu per day and is expected to support up to 25 MW of computing capability. Initially, the Company's two owned 2 MW Caterpillar natural gas generators will deliver approximately 1.6 MW net power, together powering Sterling's current fleet of 420 ASIC mining servers, representing approximately 193,500 terahashes per second (TH/s) of computing capacity.
