Haggart's October 2026 RSU Vesting and New Grant at Seagate

According to the filing, Dylan G. Haggart, a director of Seagate Technology Holdings plc (NASDAQ:STX), reported two distinct events on October 24, 2026. First, 1,580 RSUs originally awarded on October 25, 2025 under the Seagate Technology Holdings plc 2022 Equity Incentive Plan vested and were converted into 1,580 ordinary shares at a price of $0, bringing his total direct holdings to 16,095 shares before the withholding transaction.

The filing further discloses that 380 of those shares were simultaneously disposed of under transaction code F at $630.49 per share, a disposition the filing attributes to tax-related share withholding. Following this transaction, Haggart's direct beneficial ownership stood at 15,715 ordinary shares, according to the filing.

Separately, the filing reports that Haggart received a new grant of 345 RSUs on October 24, 2026, also under the 2022 Equity Incentive Plan and for no consideration. Each RSU represents a contingent right to receive one ordinary share. The filing states that release of these shares is subject to Haggart's continuous service with the issuer, with vesting occurring on the earlier of one year from grant or the date of the next annual general meeting of shareholders following the fiscal year ending July 2, 2027, provided that meeting falls at least 50 weeks after the preceding fiscal year's annual general meeting. The 345 RSUs are held directly and remain outstanding following the reported transactions.
