Digi Power X subsidiary awarded Tier 3 certification

Mr. Michel Amar reports DIGI POWER X, VIA WHOLLY-OWNED SUBSIDIARY US DATA CENTRES INC., AWARDED TIER 3 ANSI/TIA-942-C "TIA-942 READY" CERTIFICATION FOR ARMS 200 AI MODULAR PLATFORM Digi Power X Inc.'s wholly owned subsidiary, US Data Centers, Inc., has been officially awarded Tier 3 certification under the ANSI/TIA-942-C-2024 "TIA-942 Ready" standard for its flagship ARMS 200 modular artificial-intelligence-ready data centre platform. The certification was issued by EPI Certification Pte. Ltd. following a successful independent audit on Aug. 26, 2025, confirming that ARMS 200 meets the highest global standards for resilience, reliability and compliance in data centre design. Why it matters The ANSI/TIA-942 certification is among the most respected global standards in the data centre industry: Global standard: covers site location, architecture, electrical, mechanical, telecom, safety and security; Independent verification: third party audited by EPI certification, going far beyond self-declarations; Tier 3 recognition: ensures high availability with concurrent maintainability, critical for AI, enterprise and hyperscale clients; Market signalling: many hyperscalers and global enterprises require TIA-942 certification in procurement, making ARMS 200 immediately more competitive in RFPs, sales and investor engagements. Expanding AI infrastructure In parallel with this certification, Digi Power X is accelerating its AI infrastructure roadmap. The company has: Deepened its strategic partnership with Super Micro Computers, Inc. (Nasdaq: SMCI) to integrate AI-optimized rack-scale systems into the ARMS 200 platform; Completed the purchase of Nvidia B200 GPUs, which will be deployed across ARMS 200 facilities to support hyperscale AI, enterprise and cloud workloads. "Achieving the ANSI/TIA-942 Tier 3 certification reinforces our commitment to building world-class, high-availability data centres," said Alec Amar, president of Digi Power X. "For us, it's not just about compliance, it's about giving our customers, investors and partners the assurance that our facilities meet the highest global standards of reliability, security and performance."
