Cintas Corporation Reports Second Quarter Fiscal 2008

Revenue and Earnings

CINCINNATI, December 20, 2007 -- Cintas Corporation (Nasdaq:CTAS) today reported revenue for the second quarter of fiscal 2008 of $983.9 million, a 6.6% increase from the previous year’s second quarter revenue of $923.3 million.  Net income was $82.9 million and earnings per diluted share were $0.53.

Scott D. Farmer, President and Chief Executive Officer, stated, “We are pleased to announce our second quarter results, which are in line with our expectations.  Our new sales organization continues to gain momentum.  The new business results being achieved under this new organization are meeting our expectations, most notably in our emerging business units.”

Net income increased 0.4% and earnings per diluted share increased 3.9% as compared to the second quarter of fiscal 2007.  These results were impacted by an increase in the Company’s effective tax rate, which increased to 38.3% as compared to 37.3% in last year’s second quarter.  This increase was due to the second quarter impact of FASB Interpretation No. 48 (FIN 48), Accounting for Uncertainty in Income Taxes– an interpretation of FASB Statement No. 109.  The Company expects its full year fiscal 2008 effective tax rate to be the same as last year’s effective rate of 37.3%.  Results for the quarter were also impacted by the increased investment the Company has made to its sales organization over the past year.

Share Buyback

Mr. Farmer also announced, “We have resumed purchases under our authorized share buyback program.  During our second quarter, we purchased 5.2 million shares at a cost of approximately $191 million.  Since the program’s inception, we have bought back 19.4 million shares, which equates to over 11% of our outstanding stock that existed at the program’s inception.  We have $228 million in remaining authorization available under the program.”

Strong Balance Sheet and Cash Flow

The Company’s balance sheet and cash flow from operations continue to be strong.  As of November 30, 2007, the Company’s current assets exceeded current liabilities by over a three to one ratio and debt to total capitalization was 30.6%.

On December 7, 2007, subsequent to the end of the second quarter, the Company issued $250 million of 6.125% Senior Debt.  The proceeds generated from this debt issuance were used to reduce the Company’s outstanding balance under its commercial paper program.

Outlook

Mr. Farmer stated, “Our results through the second quarter continue to be in line with our expectations.  Based on these results and our current outlook for the remainder of our fiscal year, we reiterate our full fiscal year guidance of $3.9 billion to $4.1 billion in revenue and earnings per diluted share of $2.15 to $2.25.  Achieving this guidance would allow us to reach our 39th consecutive year of growth in revenue and earnings.”
