Anterix (NASDAQ: ATEX), the leader in mission-critical private wireless broadband spectrum for utilities, and Texas-New Mexico Power (TNMP) today announced a 900 MHz spectrum sale agreement. This agreement enables TNMP to deploy a mission-critical private wireless network designed to strengthen grid reliability and support essential service improvements across its territory.

Anterix’s private wireless platform is available in the market now, providing utilities with a compelling cost-to-value proposition. For a utility like TNMP – a subsidiary of TXNM Energy serving over 280,000 homes and businesses – choosing an established, market-ready ecosystem reduces the risks of unproven alternatives and helps to ensure a more secure, scalable foundation capable of supporting any utility use case. As a cornerstone of its 2025-2027 System Resiliency Plan, TNMP's investment in this proven standard will facilitate faster outage response, real-time monitoring of critical infrastructure, and the seamless integration of advanced energy technologies.

TNMP joins a significant and growing network of Texas utilities – including LCRA, Oncor, Xcel Energy, and recently announced CPS Energy – that have prioritized secure, utility-controlled communications. This collective move cements the state’s leadership in grid modernization and provides a scalable foundation for the future. Nationwide, nine utilities now leverage Anterix’s 900 MHz platform across 15 states, proving it is the only utility-focused network built to deliver both measurable operational results and a clear roadmap to 5G.

“Utilities need secure, flexible solutions that work today, and by welcoming TNMP to the ranks of nine leading utilities already on this platform, we are reinforcing that 900 MHz is the proven national choice,” said Anterix President & CEO Scott Lang. “This agreement reflects the clear market momentum toward a solution that is available now, scalable to any use case, and offers a cost-to-value ratio that makes sense for the modern grid. By joining fellow Texas utilities in this collective move, TNMP is choosing a de-risked path to grid modernization”

TNMP President Neal Walker said, “Our customers depend on us for reliable power every day, and that responsibility is the driving force behind our 2025-2027 System Resiliency Plan. By deploying Anterix’s private wireless network, we are gaining the secure, utility-controlled communications needed to achieve faster outage response and real-time monitoring of our most critical infrastructure. This proven platform provides an immediate, cost-efficient solution that allows us to scale as our customers' needs evolve, ensuring we can seamlessly integrate advanced energy technologies and deliver smarter, more dependable service to the communities we serve.”
