(the “Company”) approved Amendment No. 2 (the “Plan Amendment”) to the Anterix Inc. 2023 Stock Plan (the “2023 Plan”) at the Company’s 2026 Annual Meeting of Stockholders (the “Annual Meeting”). The Plan Amendment, which had been previously adopted by the Company’s Board of Directors on June 22, 2026, increases the number of shares of common stock (the “Common Stock”) available for issuance under the 2023 Plan by 1.0 million shares.

The foregoing description of the terms and conditions of the Plan Amendment is qualified in its entirety by reference to the full text of the Plan Amendment, a copy of which is filed as Exhibit 10.1 hereto and incorporated herein by reference.
