STERICYCLE, INC. REPORTS RESULTS

FOR FIRST QUARTER 2008

Lake Forest, Illinois, April 23, 2008—Stericycle, Inc. (NASDAQ:SRCL), today reported financial results for the first quarter 2008.

Revenues for the quarter ended March 31, 2008 were $254.8, up 20.7% from $211.0 million in the same quarter last year. Acquisitions less than 12 months old contributed approximately $19.5 million to the growth in revenues for the quarter. Gross profit was $113.6 million, up 20.5% from $94.2 million in the same quarter last year. Gross profit as a percent of revenues was 44.6% versus 44.7% in the first quarter of 2007.

After the effect of the charge described in the table below, generally accepted accounting principles (“GAAP”) net income for the first quarter of 2008 was $31.7 million or $0.35 per diluted share compared with GAAP net income of $29.4 million or $0.32 per diluted share for the same quarter last year. The impact of the charge described was to reduce net income by $3.3 million or $0.04 per diluted share. Adjusted non-GAAP net income for the first quarter of 2008 (GAAP net income without including the charge described) was $35.0 million or $0.39 per diluted share.

Cash flow from operations was $63.6 million for the first three months of 2008. Cash flow and increased loan balances were used to strengthen our business and funded $79.4 million in stock repurchases (1,482,185 shares), $11.3 million in capital spending, and $7.8 million in acquisitions and international investments.

USE OF NON-GAAP FINANCIAL MEASURES

Stericycle’s management believes that non-GAAP measures provide meaningful supplemental information regarding our performance and liquidity by excluding certain expenses that may not be indicative of our core business operating results. We include these non-GAAP financial measures because we believe they are useful to investors in allowing for

greater transparency with respect to supplemental information used by management in its financial and operational decision making. These non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results.

Safe Harbor Statement: Statements in this press release may contain forward-looking statements that involve risks and uncertainties, some of which are beyond our control (for example, general economic conditions). Our actual results could differ significantly from the results described in the forward-looking statements. Factors that could cause such differences include changes in governmental regulation of medical waste collection and treatment and increases in transportation and other operating costs, as well as the other factors described in our filings with the U.S. Securities and Exchange Commission. As a result, past financial performance should not be considered a reliable indicator of future performance, and investors should not use historical trends to anticipate future results or trends. We make no commitment to disclose any subsequent revisions to forward-looking statements.
