## The Power of 900 MHz: A Technological Moat Anterix's primary competitive advantage is rooted in its licensed 900 MHz spectrum, designated as Band 106 for LTE and n106 for 5G within the 3GPP global standard. This mid-band spectrum possesses inherent propagation characteristics that are particularly well-suited for utility applications, offering tangible benefits over alternative frequencies and technologies. Quantifiable advantages include approximately 20-30% greater coverage efficiency in rural areas, translating to potentially lower infrastructure costs for utilities compared to higher-frequency bands used by some competitors. This efficiency contributes to an estimated 15-25% lower operating cost per unit for building wide-area utility networks. The licensed nature of the spectrum ensures priority access and control, critical for mission-critical utility operations, fostering heightened efficiency, resiliency, and security. Anterix's solutions enable a quicker time-to-market for utility private networks, estimated at 20-30% faster deployment compared to navigating shared or unlicensed spectrum complexities. Furthermore, the 900 MHz band demonstrates enhanced reliability in harsh environments, with potentially lower failure rates for utility grid communications during disruptive events. The technology also offers better energy efficiency in spectrum utilization, requiring less power consumption for network operations. Anterix is not static in its technological pursuits. Recognizing the growing bandwidth demands, the company, alongside a broad coalition of utilities and industry associations, petitioned the FCC to expand the 900 MHz broadband segment from 3x3 MHz to 5x5 MHz. The FCC's adoption of a Notice of Proposed Rulemaking (NPRM) in January 2025 is a significant step, proposing to provide utilities with greater capacity for future use cases and potentially allowing them to serve other entities within their footprints. While a multi-year process, this initiative signals a potential enhancement of the spectrum's long-term value. The company is also developing complementary platform services like CatalyX for connectivity and SIM management and is actively involved in DOE/EPRI initiatives focused on enhancing grid cybersecurity, leveraging its secure network foundation. These technological advancements and strategic R&D efforts contribute directly to Anterix's competitive moat, supporting its market positioning and enabling it to address the evolving needs of the utility sector, including the integration of AI and edge computing. ## Momentum Builds: Performance, Pipeline, and Financial Strength Anterix's recent financial performance reflects the early stages of commercializing its spectrum assets and executing its strategic plan. For the fiscal year ended March 31, 2025, the company reported spectrum revenue of $6.03 million, a 44% increase from $4.19 million in FY2024, primarily driven by revenue recognition from agreements with Xcel Energy (TICKER:XEL) and Evergy (TICKER:EVRG). Despite the revenue growth, the company's net loss increased by 25% to $11.4 million in FY2025, up from $9.1 million in FY2024. This wider loss was influenced by a $3.8 million increase in severance and related charges, partially offset by the rise in spectrum revenue and higher net gains from intangible asset transactions. Gains on the sale of intangible assets, net, significantly increased by 148% to $18.3 million in FY2025, primarily due to the transfer of four broadband licenses to Oncor, while gains on the exchange of intangible assets, net, decreased by 35% to $22.8 million, reflecting the volume of narrowband-to-broadband license exchanges in the respective periods.

Operational achievements underscore the company's progress. Anterix has now secured agreements with seven leading utility customers across 15 states, representing nearly $400 million in contracted proceeds. Key recent wins include the $102.5 million agreement with Oncor and the $13.5 million expansion agreement with LCRA, which collectively mean Anterix's partners now cover 93% of Texas counties, establishing a powerful regional deployment model. The company emphasizes that its solutions have moved "from the lab to the field," with existing customers actively deploying networks and demonstrating successful use cases. To accelerate future adoption, Anterix launched the AnterixAccelerator initiative with a committed investment of up to $250 million. This program, designed to test the correlation between price and action and reduce deployment friction, has seen significant early traction and is currently oversubscribed with utilities in active discussions. Management also implemented targeted cost reductions, expecting to lower the operating expense run rate by approximately 20% annually from prior levels, further enhancing cash flow generation. ## Outlook, Strategic Acceleration, and Shareholder Value Anterix's outlook is centered on leveraging its established market leadership and financial strength to capitalize on the growing demand for private utility broadband. Management projects significant percentage growth in contracted proceeds in Fiscal Year 2026 compared to the $116 million achieved in FY2025, driven in part by the momentum generated by the AnterixAccelerator program. They anticipate continued operational expense savings and managed capital expenditures focused on spectrum clearing necessary for contract fulfillment. The company's strategic review process, initiated in February 2025 with Morgan Stanley (TICKER:MS) following inbound interest, represents a potential catalyst. While the outcome is not predetermined, the goal is to explore opportunities that could accelerate the company's efforts and deliver enhanced value to shareholders. This process, combined with the potential for the 5x5 MHz FCC expansion and the traction from the AnterixAccelerator, highlights a period of potential strategic inflection. Management believes the company's stock is currently undervalued, particularly when comparing its market capitalization to the rate at which it has successfully sold or leased spectrum. This conviction fuels their intent to be more aggressive with the share repurchase program. With $227.7 million remaining under the current authorization as of March 31, 2025, and efforts underway to accelerate cash flow timing (such as pulling $34 million into Q4 FY25), Anterix aims to utilize its financial resources to directly enhance shareholder value through buybacks. The opportunistic nature of the program allows flexibility based on market conditions and cash flow generation.
