TRINET GROUP INC

On February 23, 2024, Burton M. Goldfield, amember of the Board of Directors, adopted a new written trading plan intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act (the “Goldfield Plan”). The first possible trade date under the Goldfield Plan is May 28, 2024, and the end date of the Goldfield Plan is February 28, 2025 (subject to customary exceptions), for a duration of approximately one year. The Goldfield Plan calls for the sale of an amount of shares that Mr. Goldfield 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 Goldfield Plan depends on the number of shares to be withheld by us on equity awards that will vest during the duration of the Goldfield Plan, among other factors. For purposes of this disclosure, without

subtracting any shares to be withheld upon future vesting events, the aggregate number of shares currently expected to be sold pursuant to the Goldfield Plan is 74,379.
