UIS insider Kristen Prohl withholds 3,577 shares for taxes – Form 4

Rhea-AI Filing Summary

Unisys Corp. (UIS) – Form 4 filing dated 08/04/2025

Senior Vice President, General Counsel, Secretary & CAO Kristen Prohl reported two Rule 16b-3 “F” transactions on 08/01/2025, indicating shares were withheld by the issuer to satisfy tax obligations upon the vesting of equity awards. The insider disposed of 1,295 and 2,282 common shares, respectively, at an accounting price of $3.91 per share (≈ $14 thousand total).

Following these withholdings, Prohl’s direct ownership declined from an estimated 215,167 shares to 211,590 shares. No derivative securities were involved and there were no open-market purchases or sales. The transactions do not appear to be materially significant relative to Unisys’s share count or daily trading volume.

Insights

Equity Compensation Analyst

TL;DR: Routine tax-withholding; immaterial for investors.

The “F” code confirms these are non-discretionary share withholdings tied to vesting, not open-market sales. Only 3,577 shares (<1% of her holdings) were surrendered, worth roughly $14k. Ownership remains above 211k shares, maintaining strong alignment with shareholders. Given Unisys’s market capitalization, the transaction is de minimis and provides no directional signal on fundamentals or valuation.
