TRINET GROUP, INC.

Other Information

On February 18, 2026, Anthony Shea Treadway, our Chief Revenue Officer, adopted a new written trading plan intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act (the “Treadway Plan”). The first possible trade date under the Treadway Plan is August 19, 2026, and the end date of the Treadway Plan is August 18, 2027 (subject to customary exceptions), a duration of eighteen months. The Treadway Plan calls for the sale of an amount of shares that Mr. Treadway could receive upon the future vesting of certain outstanding equity awards, net of any shares withheld by us to satisfy applicable taxes. The exact number of shares to be sold pursuant to the Treadway Plan depends on the number of shares to be withheld by us and the amount of any additional equity awards that may be granted and that will vest during the duration of the Treadway Plan, among other factors. For purposes of this disclosure, without taking into account (i) any future equity awards granted under

the company’s equity-based incentive plans (ii) any new shares purchased under the company’s employee stock purchase plan or (iii) the subtraction of any shares to be withheld upon future vesting events, the aggregate number of shares currently expected to be sold pursuant to the Treadway Plan is 26,971.
