UNIFIRST CORP

As previously disclosed, the Merger Agreement contemplates that the Company may enter into letter agreements with certain executive officers providing for retention bonuses designed to ensure the retention of each such executive officer following the closing of the Transaction. On October 26, 2026, the Company entered into a letter agreement (each, a “Letter Agreement”) with each of Steven Sintros, the Company’s President and Chief Executive Officer, Shane O’Connor, the Company’s Executive Vice President and Chief Financial Officer, and David Katz, the Company’s Executive Vice President, Sales and Marketing (each, an “Executive”).

Each Letter Agreement (other than the Letter Agreement with Mr. Sintros) provides for a one-time cash retention bonus (the “Retention Bonus”) in the amount of $1,750,000 for Mr. O’Connor or $1,250,000 for Mr. Katz. Each Retention Bonus is payable to the applicable Executive as soon as reasonably practicable after the 120-day anniversary of the closing of the Transaction (the “Payment Date”). To receive the Retention Bonus, the Executive must be actively employed in good standing with Cintas or one of its affiliates on the Payment Date. If, after the closing of the Transaction and before the Payment Date, the Executive is terminated without "Cause" or resigns with "Good Reason" (each as defined in the Company’s Executive Employment Plan), the Executive will remain eligible to receive the Retention Bonus, with such Retention Bonus being paid in full as soon as reasonably practicable following the Executive executing and not revoking a release of claims in favor of the Company and Cintas (the “Release Requirement”).

If the Transaction is abandoned by the parties, the Retention Bonus will be paid in two installments, with 50% paid as soon as reasonably practicable after such abandonment and 50% paid as soon as reasonably practicable after the six-month anniversary of such abandonment, subject in each case to the Executive’s continued employment in good standing through the applicable payment date. Any unpaid installment will be paid if, after the abandonment, the Executive is terminated without Cause or resigns with Good Reason, subject to the satisfaction of the Release Requirement.

Each Letter Agreement also confirms that the Transaction will constitute a “Change in Control” under the Company’s Executive Employment Plan and acknowledges that, as of the closing of the Transaction, the Transaction will materially diminish the Executive’s duties, authority, and responsibilities, which gives the Executive “Good Reason” to resign from employment under the Company’s Executive Employment Plan. Each Letter Agreement also modifies the Good Reason process so that the Executive has 180 days after the closing of the Transaction to claim Good Reason.

Each Letter Agreement further provides that if the Executive resigns with Good Reason after the closing of the Transaction, and satisfies the Release Requirement, the Executive will be entitled to receive the following benefits in addition, in the case of Mr. O’Connor or Mr. Katz, to any unpaid portion of the Retention Bonus: (1) the severance benefits under Section 7 of the Executive Employment Plan, (2) prorated vesting and payment of Cintas restricted stock units received in exchange for Company restricted stock units granted in 2026, and (3) full accelerated vesting and payment of all other outstanding Company equity awards, as converted under the Merger Agreement.

The foregoing description of the Letter Agreements does not purport to be complete and is qualified in its entirety by reference to the full text of the Letter Agreements, copies of which are filed as Exhibits 10.15, 10.16, and 10.17 to this Annual Report on Form 10-K and are incorporated herein by reference.
