• Opportunity for UniFirst Team: Like UniFirst, Cintas has a nearly century-long heritage and deep family roots, and Cintas greatly respects the Croatti family and UniFirst team and the way they serve their customers. An enduring value at Cintas is the importance of its employees, whom it calls "partners," sharing collectively in the Company's success. Cintas would welcome UniFirst employees and ensure opportunities to develop and prosper within Cintas.

• Delivering Compelling, Immediate and Certain Value for UniFirst and Cintas Shareholders: Under the terms of the Proposal, UniFirst shareholders would receive an immediate and compelling 46% premium for their UniFirst shares in cash. The proposed acquisition is expected to be accretive to Cintas shareholders and would unlock attractive operating cost synergies for the combined company. 79% of UniFirst common shares are held by investors that also own Cintas stock.

Completion of the contemplated transaction is contingent upon reaching a definitive agreement and would be subject to the satisfaction of customary closing conditions, including receipt of UniFirst shareholder and required regulatory approvals. The proposed transaction would not be subject to any financing contingencies or approval by Cintas' shareholders. The cash consideration would be financed from Cintas cash on hand, committed lines of credit and/or other available sources of financing.

Cintas initially approached UniFirst and delivered an indication of interest to acquire UniFirst for $255 per share (the "Prior Proposal") on February 7, 2022, an offer that represented a 43% premium to UniFirst's closing price on that date. UniFirst summarily rejected that offer in February 2022 without any substantive engagement with Cintas. Since that time, UniFirst shares have declined 5% -- during the same period, the S&P 500 has appreciated 33% and Cintas stock has appreciated 95%.

On December 20, 2024, Cintas reiterated the Proposal and its willingness to meet with UniFirst and expressed a commitment to address UniFirst's comments outlined in UniFirst's rejection, including that Cintas may be willing to increase its Proposal of $275 per share should UniFirst's value creation plan justify such an increase. Cintas also indicated a willingness to discuss ways to preserve the UniFirst legacy post a transaction. UniFirst again refused to engage despite our best efforts to arrange collaborative discussions.

I have appreciated our prior discussions regarding the potential combination of UniFirst Corporation ("UniFirst") with Cintas Corporation ("Cintas"). As you know, we admire UniFirst for its track record of performance and the quality of its people. We firmly believe there is a compelling strategic and cultural fit between our two companies, and that Cintas would provide an excellent long-term home for UniFirst. Our combination would help maximize the success of UniFirst's operations and people over the long-term.

On behalf of Cintas, I would like to express Cintas' strong interest in pursuing a combination with UniFirst. To that end, we are pleased to submit this non-binding proposal (this "Proposal") to acquire UniFirst in a transaction with an implied total transaction value of approximately $5.2 billion. Specifically, we propose a transaction in which UniFirst shareholders will receive $275 per share for 100% of the outstanding UniFirst common and Class B shares. Common shareholders will receive value of approximately $4.2 billion and Class B shareholders will receive value of approximately $1 billion.

We believe the employees of UniFirst will be critical to the long-term success of the combined company. Cintas has a history of providing leadership and growth opportunities across its global organization to employees of acquired businesses. At the appropriate time, we look forward to discussing the retention of key talent and the best way to integrate our respective teams to ensure successful leadership of the combined business. Our objective would be to ensure that UniFirst's management and employees have the opportunity to develop and prosper within the Cintas organization.

During several of my prior conversations with Steve as well as on your earnings calls, you discussed the importance of three critical areas of investment - CRM, Brand and ERP. Interestingly, we have identified technology and brand as significant priorities for Cintas in the coming years. The priorities of our organizations being well-aligned speaks to how important these areas are and the value that could be derived by putting our companies together and leveraging these subjects for the greater benefit of our collective employees, customers and shareholders. In addition, we would be able to better leverage our infrastructure and route networks to enhance service to our customers and prospects enabling us to better compete in an increasingly competitive environment. Our opportunities together are both compelling and exciting.

I want to assure you that the proposed transaction is a top priority within our organization. Our executive management and advisors are prepared to commence private engagement immediately. We are committed to devoting the required resources that are necessary to quickly and efficiently complete our due diligence and finalize mutually acceptable definitive agreements on customary terms for a transaction of this nature. Given our familiarity with UniFirst, we will require only the completion of limited business due diligence along with customary public company legal due diligence in order to proceed with the proposed transaction.

Once again, we believe there is no better time than now to combine our companies and create a world class organization to even further benefit our customers, employees and shareholders. We are excited about this opportunity and are prepared to move forward expeditiously. Please provide a formal, written response regarding this Proposal to me no later than November 22, 2024. We welcome the opportunity to discuss this Proposal with you at your convenience.

Steve called me on Friday, November 22, 2024, to respond to our proposal from November 8, 2024 for the acquisition of 100% of the outstanding common and Class B shares of UniFirst ("UniFirst") by Cintas Corporation ("Cintas") for $275 per share (the "Proposal"). I understand from our conversation that UniFirst requires more time to respond to our Proposal. I want to reiterate that we believe the Proposal is extremely attractive to UniFirst and its shareholders.

We prefer to engage in discussions with UniFirst in private. We are ready to engage with you immediately to work towards a mutually acceptable definitive agreement, including the mix of consideration - cash or cash and stock - that would be most compelling to your shareholders. In connection with that, we would like to meet with you in person during the week of December 2nd to discuss deal terms and the path to completing a transaction. I will attend the meeting along with our CFO, General Counsel and outside counsel. Please let me know by Wednesday, November 27^th which day next week is most convenient for your team to meet. At that point we can set a location for the meeting.

As we expressed in our November 8 letter, we firmly believe there is a compelling strategic and cultural fit between our two companies. A combination would create a leading provider of business services and enhance our collective ability to serve customers and support employees, including by accelerating the benefits of ongoing investments in technology. Together, Cintas and UniFirst would be better able to meet the challenges posed by continued and increasing competition from much larger and better-capitalized companies that are focused on increasing their garment and facility solutions and investing in last mile fleets.

• Diligence. We have followed UniFirst closely for many years and conducted extensive due diligence over that time. We expect to have limited and specific confirmatory due diligence requirements.
• Timing. We would work towards signing and announcing a definitive agreement before year-end.
• Regulatory. Cintas has engaged leading regulatory counsel and is confident in the path through regulatory review and closing.
• Financing. Our Proposal is not subject to any financing condition and any cash consideration would be financed from cash on hand, committed lines of credit and/or other available sources of financing.
• Certainty. Our Board of Directors supports the proposed transaction. Cintas shareholder approval will not be required.

I want to reiterate that the proposed transaction is a top priority within our organization, and we believe there is no better time than now to combine our companies and create a world class organization to even further benefit our customers, employees and shareholders. Cintas is committed to reaching a definitive agreement and to moving forward expeditiously. I look forward to discussing next steps this week and hearing back from you by November 27^th on dates your team is available to meet in person next week.

I received your letter dated November 27, 2024 responding to my letter dated November 25, 2024 reiterating our proposal from November 8, 2024 to acquire 100% of the outstanding common and Class B shares of UniFirst ("UniFirst") by Cintas Corporation ("Cintas") for $275 per share (the "Proposal"). Your response is surprising given that in my conversation with Steve on November 22 he appeared to indicate serious consideration would be given to our Proposal, including with the help of outside advisors. Despite the fact that 79% of UniFirst common shares are held by investors that also own Cintas stock and the significant premium being offered to UniFirst shareholders, our invitation to meet with you directly to discuss our Proposal has once again been ignored. This is the second time in just under three years that you and your fellow directors have failed to have substantive engagement or discussions with Cintas regarding value-enhancing alternatives for shareholders. I am hopeful we can have further private discussions regarding our Proposal.

In our brief engagement in February 2022, you indicated that UniFirst believed that the execution of its strategic plan would deliver meaningful value to UniFirst shareholders. Yet, since February 7, 2022 when Cintas provided you an indication of interest to acquire UniFirst for $255 per share (the "Prior Proposal"), your stock has appreciated approximately 12%, approximately one-third of the 35% appreciation in the S&P 500 and well below the 134% appreciation in Cintas stock.

We prefer to engage with you in collaborative, private discussions with minimal disruption to your management team to reach a mutually acceptable definitive agreement. We want to meet with you in person during the week of December 9th, including discussions about potential sources of additional value that could allow us to increase our Proposal. As part of this direct engagement, we are also prepared to discuss a mix of cash and stock consideration if that is preferable to your shareholders.

• Diligence. We expect to have limited and specific confirmatory due diligence requirements.
• Timing. We would work towards signing and announcing a definitive agreement before year-end.
• Regulatory. Cintas has engaged leading regulatory counsel and is confident in the path through regulatory review and closing. We are prepared to have our counsel immediately engage with you and your counsel to discuss the extensive work we have done to date (including with our economist) on the regulatory front and our path to closing of the transaction.
• Financing. Our Proposal is not subject to any financing condition and any cash consideration would be financed from cash on hand, committed lines of credit and/or other available sources of financing.
• Certainty. Our Board of Directors supports the proposed transaction. Cintas shareholder approval will not be required.

As stated in our letter dated November 27, 2024, the UniFirst Board of Directors carefully considered Cintas Corporation's offer and unanimously concluded that the proposal is not in the best interests of UniFirst, its shareholders, and other stakeholders. In making its determination, the UniFirst Board of Directors considered the offer price, execution and business risks, feedback from some of UniFirst's largest shareholders by voting power, and UniFirst's future growth and value creation opportunities.

On behalf of Cintas Corporation ("Cintas"), I am writing to reiterate our proposal to acquire 100% of the outstanding common and Class B shares of UniFirst Corporation ("UniFirst") by Cintas for $275 per share in cash (the "Proposal"). In my continued effort to engage with you, I believe it's appropriate to address each of the points in your letter dated December 9, 2024. I want to provide additional clarity on each point since these considerations formed the basis for the UniFirst Board of Directors to unanimously conclude that our Proposal is not in the best interest of UniFirst, its shareholders and other stakeholders.

With respect to price, we understand that UniFirst's directors have unanimously concluded that a 44% premium offer to UniFirst's ninety-day average closing price as of December 2, 2024 does not warrant a meeting to explore how a transaction with Cintas can deliver substantial value to your shareholders. Our Proposal represents an approximate premium of 55% over UniFirst's closing price as of December 19, 2024. The rejection of our Proposal and the associated premium is surprising to us given UniFirst's 2024 stock performance as well as its stock performance over the past few years. We are confident your common shareholders would find these premiums compelling since 79% of UniFirst common shares are held by investors that also own Cintas stock.

We would also welcome a discussion regarding how this transaction would have minimal impact on UniFirst employees. At Cintas, we pride ourselves on being a great home for our employee-partners, and we believe UniFirst employees would feel the same way. UniFirst employees will be an important asset of our combined company. During our meeting, we'd be ready to share how and why we think bringing UniFirst employees into the Cintas family would be a win-win for everyone involved.

• Diligence. We expect to have limited and specific confirmatory due diligence requirements.
• Timing. We would work towards signing and announcing a definitive agreement in January, 2025.
• Regulatory. Cintas has engaged leading regulatory counsel and is confident in the path through regulatory review and closing. We are prepared to have our counsel immediately engage with you and your counsel to discuss the extensive work we have done to date (including with our economist) on the regulatory front and our path to closing the transaction.
• Financing. Our Proposal is not subject to any financing condition and any cash consideration would be financed from cash on hand, committed lines of credit and/or other available sources of financing.
• Certainty. Our Board of Directors supports the proposed transaction. Cintas shareholder approval will not be required.

Our Proposal offers a unique opportunity to deliver value to your shareholders and enhance our collective ability to serve customers and support employees, including by accelerating the benefits of ongoing investments in technology. Together, Cintas and UniFirst would be better able to meet the challenges posed by continued and increasing competition from much larger and better-capitalized companies that are focused on increasing their garment and facility solutions and investing in last mile fleets.

The terse response we received on November 27, 2024 rejecting our Proposal did not provide anything constructive on the economic terms or conditions of our Proposal. Our subsequent December 3, 2024 request for an in-person meeting, including our willingness to discuss potential sources of additional value that would allow us to increase our Proposal, was also rejected. Our most recent December 20, 2024 request for engagement included a willingness to discuss ways to preserve the UniFirst legacy and the potential to include Cynthia Croatti or her designee on the Cintas Board post a transaction.

We believe that our Proposal offers a unique opportunity to deliver value to your shareholders and enhance our collective ability to serve customers and support employees, including by accelerating the benefits of ongoing investments in technology. Like UniFirst, Cintas has a nearly century-long heritage and deep family roots, and Cintas greatly respects the Croatti family and UniFirst team and the way you serve your customers. Cintas would welcome UniFirst employees and ensure opportunities to develop and prosper within Cintas. Together, Cintas and UniFirst would be better able to meet the challenges posed by continued and increasing competition from much larger and better-capitalized companies that are focused on increasing their garment and facility solutions and investing in last mile fleets.

• Financing. Our Proposal is not subject to any financing condition and any cash consideration would be financed from cash on hand, committed lines of credit and/or other available sources of financing.
