RSU Vestings and Planned Share Sale by Seagate's Chief Commercial Officer

According to the filing, Teh Ban Seng, EVP and Chief Commercial Officer of Seagate Technology Holdings plc, reported three transactions involving ordinary shares over September 9-10, 2026. Two involved the conversion of restricted share units into ordinary shares, both coded as "M" transactions at a $0 price, meaning no cash consideration was paid upon vesting. The first vesting of 600 shares came from a grant under the 2022 Equity Incentive Plan where "one-quarter of the shares vested on September 9, 2023 and the remaining portion vested in equal quarterly installments over the following three years for a total vesting period of four years," as stated in the filing.

The second RSU vesting delivered 663 ordinary shares from a separate grant. The filing states that "one-quarter of the shares vested on September 9, 2025 and the remaining portion shall vest in equal quarterly installments over the following three years for a total vesting period of four years." Following both vestings on September 9, the reporting person's directly held ordinary shares rose to 6,473 before the subsequent sale.

On September 10, 2026, 663 ordinary shares were sold at a price of $860.09 per share. The filing notes this sale was executed "under a Rule 10b5-1 trading plan adopted by the Reporting Person on February 11, 2026." After the sale, direct beneficial ownership of ordinary shares stood at 5,810. The form was signed by Louis J. Thorson as Attorney-in-Fact for Ban Seng Teh on September 11, 2026.
