Nowicki, Chairman of the UniFirst Board of Directors. “This transaction follows a thoughtful and thorough evaluation by our Board, leadership team and members of the Croatti family, and we are unanimous in our conviction that this transaction is in the best interests of UniFirst and all our stakeholders.”

“This announcement reflects the extraordinary dedication of our Team Partners to ‘Always Deliver’ for the customers and communities we serve,” said Steven Sintros, UniFirst President and Chief Executive Officer. “As we spent time with Todd and the Cintas leadership team, it became clear that there is a deep alignment in purpose and core priorities between our two companies, including a steadfast commitment to investing in our people and driving operational excellence. Bringing together these successful, family-founded businesses will create meaningful benefits for our people and communities while advancing innovation for the benefit of our customers and the broader industry.”

“Since our founding in 1936, UniFirst has been distinguished by our strong family culture and core values – Customer Focus, Respect for Others and Commitment to Quality – and an unwavering dedication to serve the people who do the hard work,” said Cynthia, Carol and Matthew Croatti. “As stewards of that legacy, we reflected deeply on how best to build on UniFirst’s rich history as an industry pioneer and unlock additional opportunities for growth, innovation, and long-term value creation for our stakeholders. We see in Cintas a family-founded partner that both respects the strong business we have built and fundamentally shares our values.
