Sterling Digital plc

("Sterling" or the "Company")

Installation Works Commence at West Texas Site

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 commenced site installation works at the Company's West Texas site for its planned bitcoin mining operations in advance of the expected arrival of the equipment.

This marks another key moment in the Company's progression as it transitions from planning, procurement and contracting into on-site execution and operations, representing the culmination of several months of intensive preparatory work and a significant step forward in Sterling's mission to become a leading low-cost Bitcoin producer.

Stefan Michealides, CEO of Sterling Digital, commented:

"This is a defining moment for Sterling, one that marks the culmination of months of rigorous planning, engineering and procurement into tangible, operational reality. We have made substantial progress across all workstreams: site survey and geotechnical assessments are complete, grid connection agreements are in place, and our proprietary energy optimisation infrastructure is being deployed as part of the initial installation phase. This reflects the hard work across the whole of our team, and now brings Sterling significantly closer to full operational capacity."

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.
