Cintas Corporation Reports Third Quarter Sales and Profits

• Rental Organic Growth Accelerates to 7.5 percent, adjusted for 1 less workday

• Other Services Revenue rises over 15 percent

• Gross Margins improve despite higher energy costs

CINCINNATI, March 17, 2005 — Cintas Corporation (Nasdaq:CTAS) today reported revenue for the third quarter of fiscal 2005 of $755 million, an 8.4 percent increase from the previous year’s third quarter revenue of $697 million. Net income of $71.3 million increased 7.3 percent from $66.5 million last year and earnings per share of $.41 increased 5 percent from $.39 last year.

Scott D. Farmer, President and Chief Executive Officer, stated, “We are pleased to report another solid quarter of performance. Our rental revenue grew 7.5 percent on an organic basis when adjusted for one less workday this quarter, up from an organic growth rate of 6.0 percent in the second quarter and 5.8 percent in the first quarter of this fiscal year. Other services revenue, which is primarily the sale of uniforms and first aid and safety products and services, rose 15.5 percent during the quarter, and 5.7 percent organically when adjusted for the one less workday. Total revenue for the company increased 8.4 percent on a reported basis and 7.1 percent on an organic basis when adjusted for the one less workday.”

Mr. Farmer continued, “Our revenue growth continues to accelerate as we add more new customers across all of our business divisions. Recently, we expanded our product and service offerings even further by adding fire protection services, such as fire extinguishers, and further expanding our new Document Management Division to include document storage. The product and service offerings we have today give us the opportunity to achieve our goal of providing a service to every business in the United States and Canada, which encompasses more than 14 million businesses. Today, we serve only 700,000 of those businesses. We are truly expanding into a broader-based business services company as reflected in the recent change in our tagline from “Cintas, The Uniform People” to “Cintas, The Service Professionals”.

Mr. Farmer said, “For the quarter, our gross margins were a solid 42.6 percent versus 42.4 percent of revenue in the third quarter last year. This was achieved despite higher energy prices. In the quarter, selling, general and administrative costs increased to 27.0 percent from 26.5 percent of revenue in the third quarter last year, primarily as a result of continuing to increase our investment in sales and marketing programs and higher healthcare benefit costs.”

Strong Balance Sheet

The Company’s balance sheet continues to strengthen. Debt to total capitalization was 18.5 percent as of February 28, 2005, versus 21.8 percent as of February 29, 2004. Cash and marketable securities climbed to $368 million as of February 28, 2005, compared to $249 million a year ago, or a 48 percent increase. Total shareholders’ equity was $2.1 billion as of February 28, 2005.

Outlook

Mr. Farmer commented, “We have tightened our guidance for the remainder of fiscal 2005, which is within the guidance we provided at the beginning of this fiscal year. For fiscal 2005, which ends May 31, 2005, our forecast is for revenue to be in a range of $3.05 to $3.07 billion compared to fiscal 2004‘s revenue of $2.81 billion. Our guidance for earnings per share is $1.71 to $1.75 compared to $1.58 for fiscal 2004.”
