WOODLAND PARK, N.J., April 06, 2026 (GLOBE NEWSWIRE) -- Anterix (NASDAQ:ATEX), the leader in mission-critical private wireless broadband spectrum for utilities, and NorthWestern Energy announced today a milestone sale agreement, marking the first planned deployment of Anterix's 10 MHz broadband configuration in the 900 MHz band. The agreement follows the Federal Communications Commission's (FCC) unanimous February 2026 approval to expand Anterix's broadband spectrum allocation, which will effectively almost double the capacity available for utilities.

"NorthWestern Energy's territory spans vast distances across remote, rugged terrain and extreme weather conditions – exactly where our 900 MHz wireless broadband spectrum delivers unmatched, mission critical connectivity for utility communications," said Anterix President & CEO, Scott Lang. "We are proud to provide the foundation NorthWestern Energy needs to build a secure platform for a modern grid, enabling the delivery of safe, reliable energy for the communities they serve."

"The increased capacity gained from this 10 MHz broadband configuration is a solid foundation as we expand NorthWestern Energy's wireless communications network to securely and reliably modernize the grid and energy infrastructure serving our customers," said NorthWestern Energy Director of Network Engineering and Operations, Mark Maroney. "That means real-time control of remote distribution powerlines and equipment, redundant, reliable connectivity to field devices, real-time monitoring and enhanced situational awareness of our energy systems in areas at high risk for wildfire and more efficient restoration of service when outages do occur."

With this agreement, NorthWestern Energy becomes the tenth utility to secure Anterix's 900 MHz spectrum. This milestone underscores the industry-wide shift toward private, utility-controlled networks, as the preferred infrastructure for the energy transition. Beyond spectrum, Anterix continues to accelerate utility time-to-value through its TowerX™ nationwide tower access program, CatalyX® turnkey connectivity management, and the Anterix Active Ecosystem of more than 150 technology innovators.
