CMTL Form 4/A: RSU Vesting Corrected—620 Shares Withheld for Taxes

Rhea-AI Filing Summary

Daniel Gizinski, President of the S&S Communications Segment at Comtech Telecommunications Corp (CMTL), reported the vesting and settlement of restricted stock units. On 08/12/2025, 1,374 restricted stock units vested and converted into 1,374 shares of common stock on a one-for-one basis. Of those shares, 620 were withheld to cover the Reporting Person's federal, state and FICA tax obligations. The filing amends a prior Form 4 to correct the amount of shares withheld; no other changes were reported. Following the reported transactions, the tables show the Reporting Person's beneficial ownership as 25,145 shares of common stock and 36,104 shares underlying restricted stock units/derivative holdings.

Positive

• Restricted stock units vested and converted into common shares on a one-for-one basis, reflecting normal compensation settlement.
• 620 shares were withheld to cover tax obligations, indicating taxes were dealt with via share withholding rather than an open-market sale.
• An amendment was filed correcting the withheld-share amount, demonstrating corrective disclosure and compliance with reporting requirements.

Negative

• None.

Insights

Corporate Governance Expert

TL;DR: Routine insider equity compensation settlement and a corrective amendment; immaterial governance change.

The filing documents a standard vesting and tax-withholding event for an executive's restricted stock units, and an amended Form 4 solely to correct the number of shares withheld for taxes. This indicates the company and reporting person are maintaining disclosure compliance by correcting the prior report. There are no indications of additional grants, dispositions for cash, or changes in control or ownership percentage disclosed here.

Securities Analyst

TL;DR: Compensation-related issuance with tax withholding; transaction appears administrative rather than materially value-changing.

The report shows 1,374 RSUs vested and converted one-for-one into common shares, with 620 shares withheld for taxes. The amendment corrects the previously reported withheld amount. The tables list post-transaction beneficial ownership figures (25,145 common shares; 36,104 underlying derivative/RSU-related shares), which help quantify the executive's current stake but do not by themselves signal a material corporate event.
