The agenda includes electing seven directors, approving executive pay on an advisory basis, increasing shares available under the 2023 Stock Plan, choosing how often to hold future say-on-pay votes (the Board recommends one year), and ratifying Deloitte & Touche as auditor for the year ending March 31, 2027.
The proxy highlights a board where 5 of 7 nominees are independent, the Chair and CEO roles are separated, and all key committees are fully independent. In fiscal 2026, Anterix advanced its 900 MHz private broadband strategy, executing spectrum sale agreements of $13 million with CPS Energy, $3.2 million with Texas-New Mexico Power, and $7.7 million with NorthWestern Energy, and reports $127 million of contracted customer proceeds and zero debt.
Executive pay is built around base salary, an annual performance-based cash bonus, and long-term equity. For fiscal 2026, the CEO’s base salary was $564,075, with bonus targets tied mainly to customer proceeds, free cash flow, regulatory milestones, and individual performance.

The company emphasizes strong governance features such as stock ownership guidelines, an updated clawback policy, anti-hedging and anti-pledging rules, and active ESG and human capital oversight.
