[Form 4] Anterix Inc. Insider Trading Activity

Rhea-AI Filing Summary

Form 4 filing summary – Anterix Inc. (ATEX): On 08/05/2025, director and 10 % owner Jeffrey A. Altman accepted 7,767 restricted shares of ATEX common stock as non-employee director compensation (code “A”) at a $0 acquisition cost. The award vests on the earlier of 05 Aug 2026 or the next annual shareholder meeting, subject to insider-trading blackout rules.

Following the grant, Altman’s direct holdings rise to 15,416 shares. He also reports 124,492 additional directly held shares and 5,411,776 shares held indirectly via Owl Creek funds, leaving the Owl Creek/Altman group comfortably above the 10 % ownership threshold. No sales, option exercises, or derivative trades were reported, so overall economic exposure remains largely unchanged. The transaction is routine, modest in size relative to Altman’s existing 5.55 million-share exposure, and has limited impact on Anterix’s ownership structure or float.

Positive

• Director/10 % owner acquired 7,767 additional shares, modestly increasing direct alignment with shareholders.
• No insider sales reported, maintaining confidence signal and stable ownership.

Negative

• None.

Insights

Financial Analyst

TL;DR 7,767-share grant modestly lifts insider’s direct stake; no shares sold, overall exposure unchanged.

The filing shows Altman continuing to accumulate equity through routine board compensation rather than open-market purchasing. The 7.8 k-share grant is immaterial relative to his 5.4 m indirect holdings and Anterix’s 19 m share float, so market impact should be negligible. Still, the absence of sales and maintenance of a >10 % position reinforce long-term alignment between the director and shareholders.

Corporate Governance Specialist

TL;DR Standard director compensation; confirms insider retains sizable 10 %+ stake.

The award follows customary vesting terms and complies with Rule 10b5-1 safeguards. No indication of intent to dispose. Continued disclosure of indirect shares via Owl Creek funds is important for transparency, but there are no red-flags or governance concerns. Impact on voting control and free float is effectively nil.
