Item 2.02

Results of Operations and Financial Condition

On October 25, 2007 Stericycle, Inc. issued a press release announcing its financial results for the quarter ended September 30, 2007. A copy of this press release is attached hereto as Exhibit 99.1 and incorporated by reference.

The press release and accompanying balance sheet refer to Stericycle's total debt to capitalizaton percentage ratio. The total debt to capitalization percentage ratio is calculated by dividing total debt (numerator) by the sum of total debt, preferred stock, and shareholders' equity (denominator). We consider this leverage ratio to be a good indicator of the strength of a company's balance sheet and its ability to service its debt. Total debt to capitalization percentage is not a measure in accordance with accounting principles generally accepted in the United States. The ratio should not be considered as an alternative to net income, as an indicator of operating performance or as an alternative to cash flow as a measure of liquidity.
