Quest Diagnostics to Speak at Credit Suisse First Boston Health Care Conference

11/13/2001

"Our outlook remains unchanged from the guidance we provided during our Third Quarter 2001 financial conference call on October 19, 2001," said Mr. Freeman. "We remain comfortable with the consensus of analyst expectations for fourth quarter earnings of $0.48 per diluted share, as reported by First Call. We continue to expect full year earnings per diluted share before special items to grow more than 65%. In 2002, we continue to expect to deliver earnings per share growth in excess of 30%. This increase is before the additional $0.35 per diluted share we expect to realize from the change in goodwill accounting that becomes effective on January 1, 2002. We continue to remain highly confident in our ability to deliver sustainable outstanding performance for our shareholders."
