On March 31, 2023, Stericycle Inc announced that it has received shareholder proposal from The International Brotherhood of Teamsters General Fund, asking the Company to adopt a policy that in the event of a change in control, there shall be no acceleration of vesting of any performance-based share units granted to any senior executive officer, provided, however, that the board's Compensation Committee may provide in an applicable grant or purchase agreement that any unvested award will vest on a partial, pro-rata basis up to the time of the named executive officer's termination, with such qualifications for an award as the Committee may determine. In addition, the Company recommended the shareholders to vote against the proposal at the annual meeting of shareholders scheduled to be held on May 16, 2023.
