Szlosek's October 2026 RSU Activity at Seagate Technology Holdings

According to the filing, Thomas A. Szlosek, a director of Seagate Technology Holdings plc (NASDAQ:STX), reported activity across both Table I (non-derivative securities) and Table II (derivative securities) on October 24, 2026. The filing was signed by Louis J. Thorson as attorney-in-fact for Szlosek and submitted on October 26, 2026.

The filing discloses that the 1,580 RSUs awarded to Szlosek on October 25, 2025, under the 2022 Equity Incentive Plan were converted into ordinary shares on October 24, 2026, via transaction code M, at a conversion price of $0. Immediately following that conversion, 380 ordinary shares were withheld (transaction code F) at a price of $630.49 per share, a transaction type commonly associated with tax-withholding on vested equity awards. The filing notes that Szlosek's resulting direct ownership of ordinary shares stood at 1,558.39, a figure that includes 1.39 shares acquired through dividend reinvestment, as explained in footnote 1 of the filing.

Separately, the filing discloses a new award of 345 RSUs granted to Szlosek on October 24, 2026, also under the 2022 Equity Incentive Plan, for no consideration. Each RSU represents a contingent right to receive one ordinary share of the issuer. According to the filing, shares will be released "on the earlier of (i) one year from the date of grant and (ii) the date of the next annual general meeting of shareholders of the Issuer following the end of the fiscal year ending on July 2, 2027, provided such annual general meeting is at least fifty (50) weeks after the immediately preceding fiscal year's annual general meeting," subject to Szlosek's continuous service with the issuer. Following these transactions, Szlosek holds 345 RSUs directly.
