Anterix Inc. Spectrum License Sale to NorthWestern Energy

Anterix Inc., through its subsidiary PDV Spectrum Holding Company, LLC, has entered into a spectrum license sale agreement with NorthWestern Energy (NWE). Under this agreement, PDV will sell 900 MHz broadband licenses to NWE, covering portions of Montana, South Dakota, and Wyoming. The sale includes a 6 MHz broadband configuration for certain counties and a 10 MHz configuration for others, following FCC approval for the transfer of these licenses. The total contract value is $7.7 million, with payments structured between 2026 and 2033, contingent upon FCC license grants and spectrum assignment. This agreement marks a significant development, enabling NWE to deploy a private wireless broadband network for enhanced grid modernization, real-time control of infrastructure, and improved service restoration, particularly in wildfire-prone areas. This is the first planned deployment of Anterix's 10 MHz broadband configuration.
