Cintas Corporation Announces Record Sales and Earnings for the First Quarter Ended August 31, 1999

CINCINNATI, September 22, 1999 — Cintas Corporation announced today its results for the first quarter ending August 31, 1999. Prior year numbers reflect the restatement of Cintas financial results to include the impact of the acquisition of Unitog in March 1999 which was accounted for as a pooling of interests. Net income of $43 million increased 19% over the first quarter results of last year. Basic earnings per share of $.39 and diluted earnings per share of $.38 increased 18% and 15%, respectively, over the first quarter last year. Revenues were $457 million, an increase of 7% over the $426 million for last year. Rental revenues increased 9% from the first quarter last year despite the sale of some of the business previously acquired in acquisitions, including Unitog. Excluding these divestitures, rental revenues would have increased 11%.

Richard T. Farmer, Chairman of the Cincinnati based uniform company, commented, "The integration of Unitog is ahead of schedule, and we are very pleased with our net income improvement in the quarter. As we stated when we completed the Unitog transaction, our first goal is to take advantage of the significant profit improvement opportunities we have with the Unitog operations. Our results for the first quarter indicate that we are accomplishing this goal despite the lower revenues compared to last year from those acquired operations. Cintas currently services over 350,000 business customers from its network of approximately 300 operating locations. We are well on the way to completing our 31st consecutive year of growth in sales and profits."

Cintas is a leader in the corporate identity uniform business and also provides many ancillary services including entrance mats, sanitation supplies, first aid products and services and cleanroom services. Cintas is publicly-traded over the Nasdaq under the symbol CTAS.
