Digi Power X Achieves Tier III Certification for ARMS 200, Sets Near-Term Deployment Timeline and Provides September 2025 Operational Update

This news release constitutes a "designated news release" for the purposes of the Company's prospectus supplement dated May 30, 2025 to its short form base shelf prospectus dated May 15, 2025.

MIAMI, Oct. 01, 2025 (GLOBE NEWSWIRE) -- Digi Power X Inc. ("Digi Power X" or the "Company") (NASDAQ:DGXX, TSXV:DGX), an innovative energy infrastructure company, is pleased to provide unaudited comparative production results for the month ended September 30, 2025, combined with an operations update. All monetary references are expressed in U.S. dollars unless otherwise indicated.

As previously announced, Digi Power X recently achieved a major milestone in its AI strategy: the Company's ARMS 200 (AI-Ready Modular Solution) has achieved Tier III certification under the globally recognized ANSI/TIA-942 standard, validated by EPI, the global leader in data center audits. This certification makes ARMS 200 one of the very few modular AI data-center platforms worldwide to receive Tier III certification, providing:

• High availability (99.982%) with redundant and concurrently maintainable systems;
• Enterprise-grade reliability for mission-critical AI, cloud and blockchain workloads; and
• Customer trust and compliance, with certification validated by EPI.
  
  
  
  

Near-Term Deployment Catalyst

The first Tier III certified ARMS 200 pod is scheduled for delivery at Digi Power X's Alabama facility by the end of November 2025, with commissioning planned for December 2025. From this foundation, Digi Power X plans to expand into ARMS 500 (5MW) and ARMS 1000 (10MW) clusters, offering customers flexible scaling with Tier III reliability.

Each ARMS unit is engineered for rapid deployment within approximately 180 days of delivery, providing a faster path to AI capacity than traditional data centers.

Strategic Partnership with Supermicro

Digi Power X has deepened its strategic partnership with Super Micro Computer, Inc. ("Supermicro"), integrating AI-optimized rack-scale systems into the ARMS platform. This is expected to position the Company as a turnkey provider of Tier III-ready AI infrastructure at scale.

Strong Balance Sheet and Crypto-Backed Expansion

• The Company held cash, Bitcoin ("BTC"), Ethereum ("ETH") and cash deposits of approximately $29 million as of September 30, 2025, as compared to $29 million on August 31, 2025 (based on a BTC price of $113,300 as of September 30, 2025, and $108,200 as of August 31, 2025, per CoinMarketCap, and an ETH price of $4,160 as of September 30, 2025, and $4,390 as of August 31, 2025, per CoinMarketCap).
  
  
  
  
• Digi Power X expanded its inventory of BTC from approximately 85 BTC as of August 31, 2025, to 100 BTC as of September 30, 2025, representing an increase of 18% over the previous month, through its mining activities (as described in more detail below).
  
  
  
  
• Digi Power X held approximately 1,000 ETH as of September 30, 2025, representing a fair market value of approximately $4.2 million (based on an ETH price of $4,160 as of September 30, 2025, per CoinMarketCap), as compared to a fair market value of approximately $4.4 million as of August 31, 2025 (based on an ETH price of $4,390 as of August 31, 2025, per CoinMarketCap). The Company's ETH position is currently staked to generate an annualized return of roughly 3% in rewards. This yield provides an additional recurring revenue stream while maintaining exposure to ETH's long-term appreciation potential.
  
  
  
  
• The value of BTC produced at the Company's facilities between its self-mining and colocation agreements and energy sales was approximately $3.4 million on September 30, 2025 (based on a BTC price of $113,300 as of September 30, 2025, per CoinMarketCap).
  
  
  
  
• Miners running at the Company's facilities produced approximately 25 BTC during the month between self-mining and colocation agreements, representing an approximate value of $2.8 million (based on a BTC price of $113,300 as of September 30, 2025, per CoinMarketCap).
  
  
  
  
• The Company has invested approximately $5.8 million year-to-date in capital expenditures and mining infrastructure support equipment, including approximately $0.3 million in September.
  
  
  
  

Growing Infrastructure Footprint

The Company currently operates with approximately 100 MW of available power across three sites, with plans to expand to 200 MW+ through organic growth and targeted acquisitions. BTC mining will continue at the Company's other sites, including by next-generation hydro-powered systems that are scheduled for Q1 2026 deployment.

"Tier III certification for ARMS 200 represents a turning point for Digi Power X. We are now positioned among a very small group of companies worldwide that can deliver modular, enterprise grade AI data centers on rapid deployment timelines. With our first ARMS 200 pod arriving in Alabama this November, and our partnership with Supermicro providing rack-scale AI systems, Digi Power X is building a differentiated platform for hyperscale-ready AI growth," said Michel Amar, CEO of Digi Power X.
