Sterling Digital plc

("Sterling" or the "Company")

Entry into Gas Purchase Agreement

Sterling Digital plc (AQSE: ASIC),  a company established to develop low-energy-cost digital asset mining operations in the United States, announces that it has entered into a gas purchase agreement (the "Agreement") with a US based supplier  (the "Supplier") for the supply of natural gas to power its bitcoin mining operations in West Texas, US.

The key commercial terms of the Agreement are as follows:

·    The Agreement becomes effective once the Supplier confirms its facilities are ready to deliver gas, with Sterling required to receive such gas within 90 days of that notice.

·    The initial term of the Agreement is five years, with the option to extend for up to two further one-year periods

·    The Agreement provides the Company with surface-use rights over a 1.5 acre parcel of land in Martin County, Texas, to establish its mining site.

·    The Company will pay the average WAHA gas price based on the preceding two months, plus a transportation fee of US$0.33 per MMBtu and a service fee of US$0.22 per MMBtu.

·    The Company has committed to purchasing a minimum of 96,360 MMBtu of gas per year across the first four years of the Agreement (385,440 MMBtu in aggregate), with the Supplier guaranteeing availability of up to 6,500 MMBtu per day during the initial  term.

·    Prior to the initial supply of gas, the Company will pay a deposit equivalent to 61 days of estimated consumption, to be held in escrow and fully refundable to the extent unused, on expiry or termination of the Agreement.

The Agreement marks a significant operational milestone in the Company's development. Under its terms, natural gas will be supplied to the Company's facility by accessing the underutilised, and economically stranded WAHA pipeline in West Texas, with the Agreement establishing a formal framework for the purchase and delivery of gas. This provides a clear pathway to powering the Company's first mining operations. The Company is now ready to begin gas offtake.

The gas supply secured under the Agreement is expected to be sufficient to support up to 25 megawatts ("MW") of computing capability. In securing access to a natural gas supply that would otherwise go unutilised, the Company is positioned to generate electricity using a supply model which secures the Company's ambition to build a cost-competitive mining operation underpinned by a low-cost energy source.

Stefan Michealides, CEO of Sterling, commented:

"The signing of this five-year Gas Purchase Agreement is an important and key operational step for the Company. We now have access to a reliable, competitively priced supply of up to 6,500 MMBtu per day, supporting our strategy of developing low-cost, energy-led bitcoin mining operations.

"With the commercial framework now in place and offtake ready to begin, Sterling is now a step closer to commencing production."

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

About Sterling Digital plc

Sterling Digital plc was incorporated for the purpose of establishing a Bitcoin mining business and was admitted to trading on the AQSE Growth Market on 1 December 2025. The Company intends to locate modular, self-contained Bitcoin mining operations directly on stranded gas fields in the United States, providing the Company with a low-cost energy solution for its mining operations.

 The Company's objective is to deliver sustainable long-term capital growth for shareholders via:

• compounding Bitcoin exposure via cheapest-in-class mining; and

• active management of the Company's Bitcoin reserves.

Sterling Digital's strategy of utilising stranded natural gas to generate its electricity requirements enables the Company to produce Bitcoin at materially lower costs than comparable grid-connected miners, while simultaneously achieving ESG alignment by monetising gas resources that are otherwise flared as a by-product of the oil and gas industry.  This model delivers both enhanced mining efficiency and a significant competitive cost advantage within the Bitcoin mining sector.

The Company benefits from a highly experienced management team with proven track records across Bitcoin mining, energy management, fintech and capital markets. Their combined expertise spans modular mining deployments, power infrastructure, capital raising, and regulated crypto exchange operations.
