Anterix, Inc.

Overview

  • Owns and monetizes licensed 900 MHz spectrum (896–901 / 935–940 MHz) across the contiguous U.S., Hawaii, Alaska, and Puerto Rico.
  • Transitioning from a lease-centric model to a broader operating model that includes securing and expanding spectrum, clearing/retuning incumbents, selling and leasing spectrum, and building a portfolio of spectrum-based products and services.
  • Targets private wireless networks for utilities and critical infrastructure customers to support grid modernization, operational resilience, cybersecurity, remote automation, real-time monitoring, and edge-enabled applications.
  • Introduced a new brand identity and expanded product ecosystem in fiscal 2026 to reflect this evolution.

Business model and strategic evolution (fiscal 2026)

  • Four recurring activities:
    1. Secure and expand spectrum holdings.
    2. Clear and retune incumbents to convert narrowband to broadband.
    3. Monetize spectrum through sales or long-term leases.
    4. Develop and deliver products and services to drive recurring revenue as networks are deployed and operated.
  • Launched integrated platform offerings to reduce deployment complexity and enable scalable solutions:
    • TowerX: turnkey tower-site access service (in collaboration with Crown Castle).
    • CatalyX: turnkey connectivity management (SIM management, private-to-public roaming, device visibility).
    • Anterix Active Ecosystem (AAE): ecosystem of more than 150 technology innovators.
  • Customer focus: utilities and critical infrastructure enterprises implementing private LTE/PLTE networks on 900 MHz spectrum.
  • In February 2026 the FCC adopted the 2026 Report and Order, expanding the broadband segment to 10 MHz (5 x 5). The company continues to pursue licenses, clearing, and monetization under the updated framework.

Spectrum assets and licensing status

  • Primary asset: 900 MHz band (Band 8 family) licensed nationwide across the contiguous U.S. and some territories.
  • Licensing framework and strategy:
    • Originally structured with a 3 x 3 MHz broadband segment and two narrowband segments under the FCC’s 2020 Report and Order, using eligibility tests (50% Licensed Spectrum Test, 90% Broadband Segment Test, and 240 Channel Requirement). The 2026 Order introduced 5 x 5 rules and a 10 MHz broadband segment.
    • Complex Systems exemption: incumbents operating Complex Systems are exempt from Mandatory Retuning, affecting license eligibility in certain counties.
    • Pursues voluntary exchanges, acquisitions, retuning, and Anti-Windfall Payments to qualify for broadband licenses across counties.
    • Began filing for broadband licenses in May 2021 and has filed applications and surrendered underlying licenses as broadband licenses are granted.

Licenses and counties (high-level)

  • 419 counties licensed for broadband by the FCC (159 licenses transferred to customers).
  • 155 counties with broadband licenses delivered to customers.
  • The county-level framework uses 3,233 U.S. counties as the base unit for license eligibility.
  • 900 MHz assets include a substantial number of channels across counties, with ongoing clearing and conversion activities where incumbents remain.

  • The 2026 Order expanded the broadband segment to 10 MHz (two 5 MHz blocks) and changed license-eligibility mechanics, which affects county-level strategy and license pursuit.
  • FirstNet (FRNA/NPSBN) is a potential competitive influence for certain customers.
