Items 4 and 5 are incorporated by reference in this Item 3 as if fully set forth herein. Pursuant to, and subject to the terms and conditions contained in, the Voting Agreement described in Item 4 of this statement, the Reporting Person may be deemed to have acquired beneficial ownership of the Subject Shares (as defined below) by virtue of the execution of the Voting Agreements (as defined in Item 4 below) among Cintas Corporation and certain shareholders of UniFirst party thereto (each, a "Voting Party" and together the "Voting Parties"). The shares of Common Stock and Class B Common Stock beneficially owned by the Voting Parties have not been purchased by the Reporting Person, and thus no payments were made by or on behalf of the Reporting Person in connection with the execution of the Merger Agreement (as defined in Item 4 below) or the execution of the Voting Agreement. The Voting Parties will receive the same consideration per share of Common Stock or Class B Common Stock, as applicable, as other shareholders receive pursuant to the terms of the Merger Agreement.

Items 3 and 5 are incorporated by reference in this Item 4 as if fully set forth herein. The purpose of the Mergers (as defined below) is for Cintas Corporation to acquire control of, and the entire equity interest in, the Issuer. Merger Agreement On March 10, 2026, Cintas Corporation, a Washington corporation ("Cintas"), entered into an Agreement and Plan of Merger (the "Merger Agreement") with (i) UniFirst Corporation, a Massachusetts corporation ("UniFirst"), (ii) Bruin Merger Sub I, Inc., a Delaware corporation and a wholly owned subsidiary of Cintas ("Merger Sub Inc."), and (iii) Bruin Merger Sub II, LLC, a Delaware limited liability company and a wholly owned subsidiary of Cintas ("Merger Sub LLC"). The Merger Agreement provides, among other things, that, on the terms and subject to the conditions set forth therein (i) Merger Sub Inc. will be merged with and into UniFirst (the "First Merger"), whereupon the separate existence of Merger Sub Inc. will cease, and UniFirst will continue as the surviving corporation of the First Merger and a wholly owned subsidiary of Cintas and (ii) immediately after the First Merger, UniFirst will be merged with and into Merger Sub LLC (the "Second Merger," and, together with the First Merger, the "Mergers"), whereupon the separate existence of UniFirst will cease, and Merger Sub LLC will continue as the surviving entity of the Second Merger and a wholly owned subsidiary of Cintas. Merger Consideration At the effective time of the First Merger (the "First Effective Time"), each share of (i) common stock, par value $0.10 per share, of UniFirst and (ii) Class B common stock, par value $0.10 per share, of UniFirst (clauses (i) and (ii), the "UniFirst Common Stock"), issued and outstanding immediately prior to the First Effective Time (other than shares of UniFirst Common Stock held in UniFirst's treasury or held directly by a subsidiary of UniFirst, Cintas, Merger Sub Inc. or Merger Sub LLC) will convert into the right to receive: (A) $ 155 in cash (the "Per Share Cash Amount") and (B) 0.7720 shares of fully paid and nonassessable Cintas common stock (the "Cintas Common Stock"), no par value (the "Per Share Stock Amount", and collectively with the Per Share Cash Amount, and if applicable, cash in lieu of fractional shares of Cintas Common Stock, the "Merger Consideration"). No fractional shares of Cintas Common Stock will be issued in the Mergers, and holders of UniFirst Common Stock will receive cash in lieu of any fractional shares of Cintas Common Stock. Treatment of UniFirst Equity Awards On the terms and subject to the conditions set forth in the Merger Agreement, at the First Effective Time, each outstanding UniFirst equity and cash-based award will be treated as follows: o Restricted Stock Unit Awards. Each Terminating Company RSU Award (as defined in the Merger Agreement) will be canceled and converted into the right to receive the Merger Consideration in respect of the number of shares of UniFirst Common Stock subject to the Outstanding Company RSU Award (as defined in the Merger Agreement) immediately prior to the First Effective Time. Each Continuing Company RSU Award (as defined in the Merger Agreement) will be assumed by Cintas and converted into a restricted stock unit award of Cintas (each, a "Converted RSU") with respect to a number of shares of Cintas Common Stock equal to the product (rounded down to the nearest whole share) obtained by multiplying (A) the number of shares of UniFirst Common Stock subject to the Continuing RSU Award immediately prior to the First Effective Time by (B) the Equity Award Conversion Ratio (as defined in the Merger Agreement), and each such Converted RSU that is assumed and converted will continue to have, and will be subject to, the same terms and conditions that applied to the corresponding Continuing Company RSU Award immediately prior to the First Effective Time. o Stock Appreciation Awards. Each Terminating Company SAR Award (as defined in the Merger Agreement) will be deemed exercised immediately prior to the First Effective Time for a number of shares of UniFirst Common Stock (the "Company SAR Shares") equal to the excess, if any of (A) the number of shares of UniFirst Common Stock subject to such Terminating Company SAR Award immediately prior to the First Effective Time less (B) the number of shares of UniFirst Common Stock (rounded up to the nearest whole share) having a fair market value (determined by reference to the Company Final Price (as defined in the Merger Agreement)) equal to the aggregate per-share exercise price applicable to such Terminating Company SAR Award, and the Company SAR Shares shall be canceled and converted upon the First Effective Time into the right to receive the Merger Consideration. Each Continuing Company SAR Award (as defined in the Merger Agreement) will be assumed by Cintas and converted into a stock-settled appreciation right of Cintas (each, a "Converted SAR Award") with respect to a number of shares of Cintas Common Stock equal to the product (rounded down to the nearest whole share), obtained by multiplying (A) the number of shares of UniFirst Common Stock subject to the Continuing Company SAR Award immediately prior to the First Effective Time by (B) the Equity Award Conversion Ratio, with such Converted SAR Award having a per-share exercise price equal to (i) the per-share exercise price of the Continuing Company SAR Award immediately prior to the First Effective Time divided by (ii) the Equity Award Conversion Ratio (rounded up to the nearest cent), and each such Converted SAR Award that is assumed and converted will continue to have, and will be subject to, the same terms and conditions that applied to the corresponding Continuing Company SAR Award immediately prior to the First Effective Time. Each Terminating Company SAR Award for which the applicable per-share exercise price exceeds the Company Final Price shall be canceled as of the First Effective Time for no consideration. o Performance Unit Awards. Each Terminating Company PSU Award (as defined in the Merger Agreement) will be canceled and converted into the right to receive the Merger Consideration in respect of the number of shares of UniFirst Common Stock subject to the Outstanding Company PSU Award (as defined in the Merger Agreement) immediately prior to the First Effective Time, with such number determined based on the Deemed Performance Level (as defined in the Merger Agreement). Each Continuing Company PSU Award (as defined in the Merger Agreement) will be assumed by Cintas and converted into an award of Converted RSUs with respect to a number of shares of Cintas Common Stock equal to the product (rounded down to the nearest whole share), obtained by multiplying (A) the number of shares of UniFirst Common Stock subject to the Continuing Company PSU Award immediately prior to the First Effective Time (with such number determined based on the Deemed Performance Level) by (B) the Equity Award Conversion Ratio. Except as otherwise provided in Merger Agreement, each Converted RSU assumed and converted will continue to have, and will be subject to, the same terms and conditions (including time-based vesting conditions, but excluding any performance-based vesting conditions) that applied to the corresponding Continuing Company PSU Award immediately prior to the First Effective Time. Representations and Warranties; Covenants The Merger Agreement contains customary representations and warranties of both UniFirst, on one hand, and Cintas, Merger Sub Inc. and Merger Sub LLC, on the other hand, and the parties have agreed to customary covenants, including, among others, relating to (i) the conduct of UniFirst's business during the period between the execution of the Merger Agreement and the First Effective Time, (ii) the obligation of UniFirst to call a meeting of its shareholders and (iii) UniFirst's non-solicitation obligations related to alternative business combination proposals.
