Team Partners,

I am sharing the attached letter from Cintas’ CEO Todd Schneider, which includes a link to a brief video message. We are excited about the transaction we announced last week and think it is important that all our Team Partners hear from Todd directly about the opportunities for UniFirst Team Partners and the benefits of the combined company. If you lead a team that does not have access to email, please ensure that all Team Partners have the opportunity to view the video by the end of next week.

Thank you for everything you continue to do for our customers and for one another.

Sincerely,

Steven S. Sintros

RE: A Message From Cintas President & CEO Todd Schneider

UniFirst Team Partners,

On behalf of everyone at Cintas, I want to reiterate how excited we are to bring our two companies together. I hope you will take a couple minutes to watch a short video message from me, where I express my enthusiasm for the future, initial details on what you can expect post-close and what I believe we can accomplish together.

Both of our companies have a dedication, professionalism and commitment to service excellence that enable us to deliver essential workday solutions to businesses and workers across North America every day. We look forward to welcoming the overwhelming majority of the UniFirst team to Cintas once the deal closes to build on the proud histories of both of our organizations. We’re confident that by coming together we’ll create new opportunities for our employees and deliver even more value to the customers we serve in an increasingly competitive market.

We will have more opportunities to be in touch in the months to come, but I will close by reiterating how excited I am about what this next chapter will bring as we move forward together.

All my best,

Todd Schneider

President and CEO, Cintas

The following is the transcript of the video message referenced in the note from Todd Schneider, President & CEO of Cintas to all UniFirst Partners:

Hello everyone, I’m Todd Scheider, President and CEO of Cintas.

By now you’ve heard about our plans to combine UniFirst and Cintas.

We’ve long admired the business that you’ve built. The extended courting process we’ve had with your leadership team, the Board and the Croatti family has only reinforced our belief that our two companies’ cultures are a great match.

Both the Croatti family and Cintas’ founding family, the Farmers, have built highly successful companies based on hard work and personal relationships.

Both organizations rank our people and our customers as really what makes us special.

The most important thing I want to tell you today is that on day one, you become a Cintas partner.

In a merger like this, all UniFirst team members become Cintas partners immediately and we honor your start date with UniFirst. Meaning for purposes of paid time off, 401(k), profit sharing, medical benefits and all benefits, we treat your start date with UniFirst as your start date with Cintas.

You may ask yourself, “does Cintas really need me?” But to put it simply, we don’t have a bench of people at Cintas to serve an additional 300,000 customers.

We need all kinds of talented people. If you’re an RSR, we need you to serve customers. If you’re a sales rep, we want to grow our business. We need your help. If you’re a divisional director of ops, we need the most talented people to run businesses.

And this is all separate from needing people to get products ready to be delivered to customers, which is incredibly important.

I thought it was really important that you hear all this directly from me as there has been and will be plenty of rumors in the marketplace that simply are not true.

Now integrating two businesses is never simple and change is always hard, but I’m simply asking that you give us a chance.

I think what you’ll find when we combine our organizations together, we’re going to be that much more successful.

But the most important resource in every single business is the people. The people take care of the customers, and without a customer you don’t have a business.

By joining forces, we’ll be better positioned to be highly successful and serve more customers, which will create more opportunities for the employee-partners involved in the business.

We’ve competed for years, and we’ll continue to do so until we’ve closed on our deal, but our companies have a lot more in common than you might think.

I’ll be back in touch as things progress, but in the meantime, take care of your customers and each other.

Thank you.

These factors are not necessarily all of the factors that could cause Cintas’, UniFirst’s or the combined company’s actual results, performance, or achievements to differ materially from those expressed in or implied by any forward-looking statements. Other unknown or unpredictable factors also could harm Cintas’, UniFirst’s or the combined company’s results.
