Cintas’ reportable operating segments are Uniform Rental and Facility Services and First Aid and Safety Services. The Uniform Rental and Facility Services reportable operating segment consists of the rental and servicing of uniforms and other garments including flame resistant clothing, mats, mops and shop towels and other ancillary items.

The CODM is responsible for setting the Company's strategic direction, managing overall operations and is the main point of communications between the Board and key operational personnel within the organization. The CODM evaluates each operating segment's performance primarily based on revenue and operating income, using this information to guide strategic decisions and allocate resources across the Company. The accounting policies of the operating segments are the same as those described in Note 1 entitled Significant Accounting Policies.
