SUPPLEMENT TO PROXY STATEMENT DATED JUNE 25, 2026
FOR THE ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD ON AUGUST 4, 2026
Anterix Inc.
3 Garret Mountain Plaza
Suite 401
Woodland Park, NJ 07424
Dear Stockholders,
The additional information provided herein supplements, and should be read in conjunction with, the information regarding Proposal 3 - Amendment No. 2 to the 2023 Stock Plan ("Proposal 3") contained in the definitive proxy statement (the "Proxy Statement") of Anterix Inc. ("we," "us," "our" or the "Company") filed with the Securities and Exchange Commission on June 25, 2026, regarding the annual meeting of stockholders to be held on August 4, 2026, at 9:30 a.m. EDT (the "2026 Annual Meeting"). Except as supplemented by the information contained herein, all information set forth in the Proxy Statement remains unchanged. This supplement does not reflect any other events occurring after the date of the Proxy Statement or modify or update disclosures that may have been affected by subsequent events. From and after the date of this supplement, any references to the Proxy Statement will be deemed to include the Proxy Statement as supplemented hereby. Capitalized terms used herein, unless otherwise defined, have the meanings set forth in the Proxy Statement.
As more specifically described in the Proxy Statement, we are seeking stockholder approval of Amendment No. 2 (the "Amendment") to the Anterix Inc. 2023 Stock Plan (as amended from time-to-time, the "2023 Plan"), in order to increase the number of shares available for issuance under the 2023 Plan by 1.0 million shares. The Amendment was approved by the Company's Board of Directors (the "Board") on June 22, 2026.
On July 15, 2026, Institutional Shareholder Services ("ISS") issued its Proxy Analysis & Benchmark Policy Voting Recommendations (the "ISS Report") related to our 2026 Annual Meeting. In the ISS Report, ISS recommended that stockholders vote against Proposal 3. The information below addresses the concerns outlined in the ISS Report and provides supplemental data to support Proposal 3 and the size of the share increase to 2023 Plan approved and recommended by the Board. We are providing this additional information to help ensure that our stockholders have an opportunity to vote their shares on the basis of complete information.
The 2023 Plan share increase is reasonable.
Among the reasons provided by ISS for its negative voting recommendation was the determination by ISS that the size of the share increase (i.e., 1.0 million shares) we requested in Proposal 3 exceeded applicable ISS benchmarks. In reaching this determination, ISS utilized capitalization data as of March 31, 2026, the end of our 2026 fiscal year. In determining the share increase request in Proposal 3, our Board considered capitalization data as of June 11, 2026 (the record date for the 2026 Annual Meeting), as outlined in the table below. In addition, we are providing supplemental information regarding the current overhang of our outstanding equity awards and the dilutive impact of our share increase request. Correcting these assumptions and providing this supplemental information, we believe, will bring our share increase request within the parameters of ISS guidelines.
Updated 2023 Plan Details.
As of June 11, 2026, there were a total of 279,420 shares of common stock that remained available for future awards under the 2023 Plan. Also as of June 11, 2026, there were 480,823 full value awards (e.g., RSUs, PSUs) and 1,518,488 appreciation awards (i.e., stock options and stock appreciation rights) outstanding. The weighted average exercise price and remaining term of such appreciation awards were $39.45 and 7.52 years, respectively.

(1)Overhang (number of shares subject to equity awards outstanding at maximum level but not exercised, plus number of shares available to be granted, divided by total shares of common stock outstanding at the end of the year plus the total number of shares available for issuance and outstanding awards) covers shares available prior to request and total shares subject to outstanding awards.
(2)Basic dilution is the total number of shares subject to equity awards granted (at stretch level and less cancellations), including the new share request divided by the total shares of common stock outstanding.
THE BOARD REITERATES ITS RECOMMENDATION THAT YOU VOTE "FOR" THE APPROVAL OF PROPOSAL 3.
If you have already voted, you do not need to vote again unless you would like to change or revoke your prior vote on any proposal. If you would like to change or revoke your prior vote on any proposal, please refer to page 6 of the Proxy Statement for instructions on how to do so.
Sincerely,
Gena L. Ashe
Chief Legal Officer and Corporate Secretary
