STERICYCLE, INC. REPORTS RESULTS

FOR THIRD QUARTER 2009

Lake Forest, Illinois, October 27, 2009—Stericycle, Inc. (NASDAQ:SRCL), today reported financial results for the third quarter of 2009.

Revenues for the quarter ending September 30, 2009 were $297.8 million, up 7.5% from $277.1 million in the same quarter last year. Acquisitions less than 12 months old contributed approximately $19.3 million to the growth in revenues for the quarter. Revenues increased 11.1% compared to the third quarter of 2008 when adjusted for unfavorable foreign exchange impacts of $10.1 million. Regulated returns management services revenues for the quarter were $16.0 million compared with $16.1 million for the third quarter of 2008. Gross profit was $140.9 million, up 14.5% from $123.0 million in the same quarter last year. Gross profit as a percent of revenue was 47.3% compared with 44.4% in the third quarter of 2008.

Net income for the third quarter of 2009 was $46.5 million or $0.54 per diluted share compared with net income of $39.2 million or $0.45 per diluted share for the third quarter of 2008.  Net income for the third quarter of 2008 included the effect of $0.1 million of charges related to an arbitration settlement, and net income for the third quarter of 2009 included the effect of $3.3 million of transactional expenses related to acquisitions offset by $1.8 million net release of prior years’ tax reserves.  Adjusted for these charges, earnings per diluted share increased from $0.45 in the third quarter of 2008 to $0.55 in the third quarter of 2009 or up 23.6% (see table below).

For the nine months ending September 30, 2009, revenues were $864.2 million, up 6.7% from $809.7 million in the same period last year. Revenues

increased 11.7% compared with the prior year-to-date when adjusted for  unfavorable foreign exchange impacts of $40.6 million. Regulated returns management services revenues were $54.0 million compared with $58.6 million in the same period last year. Gross profit was $405.3 million, up 12.6% from $359.8 million in the same period last year. Gross profit as a percent of revenues was 46.9% versus 44.4% in the same period in 2008. Earnings per diluted share increased 22.0% to $1.51 from $1.24 per diluted share in the same period last year. Net income for the nine months of 2008 included the effect of $3.5 million of charges related to an arbitration settlement, and net income for the nine months of 2009 included the effect of $4.8 million of transactional expenses related to acquisitions offset by $1.8 million net release of prior years’ tax reserves. Adjusted for these charges, the earnings per diluted share increased from $1.28 to $1.54, or 21.0% (see table below):
