REPORTS THIRD QUARTER 1997 OPERATING RESULTS ELGIN, ILLINOIS -- SEPTEMBER 29, 1997 -- Safety-Kleen Corp. (NYSE:SK) today announced results for its third quarter ended Sept. 6, 1997. Consolidated revenue for the 12-week period was $230 million, an increase of 8% compared with the similar period in 1996. Net earnings rose to $15.1 million, an increase of 8% over the $14.0 million reported in the third quarter of 1996. On a per share basis, earnings were $0.26, compared with $0.24 in the same quarter one year ago. The Company reported average shares outstanding were approximately 58.7 million. For the first thirty-six weeks of 1997, consolidated revenue was $680 million, an increase of 9% compared with $626 million during the same period in 1996. Net earnings were $40.3 million, relatively unchanged from $40.7 million during the same period one year ago. Year-to-date earnings per share were $0.69 compared with $0.70 per share in 1996. Commenting on the results, Joseph Chalhoub, President and Chief Operating Officer noted, "Excluding the impact of a stronger dollar, on a year-over-year basis consolidated revenue for the quarter was up 9%. Our Industrial Services revenue for the third quarter grew 11% and Automotive Services increased 10% compared with the prior year quarter. We also saw Imaging reach break-even at the gross profit line, another plus for this quarter," Chalhoub noted. The Company's Oil Recovery Service ("ORS") also netted a small profit during the third quarter on a revenue increase of 5%. "We continue to see earnings improvement on a sequential - MORE - [logo] PRINTED ON RECYCLED PAPER. Safety-Kleen Corp. ADD ONE basis in our ORS business due primarily to the aggressive cost reduction program we have in place," Chalhoub added. Safety-Kleen also noted that its newer businesses, Imaging, Vacuum Services, and Lab Pack contributed approximately $14 million in revenue during the quarter and are on track to exceed their goal of $50 million in combined revenue for 1997. "We expect these businesses to continue to grow rapidly for the foreseeable future and ultimately contribute gross profit margins comparable to our established businesses. At present, our Industrial Waste Services business offers considerable growth opportunities for the Company and we are testing new services that we hope to announce shortly," Chalhoub said. Andrew Campbell, Chief Financial Officer of the Company added, "SG&A expenses declined 4.4% from the previous quarter to approximately 13.6% of revenue due in part to lower employee-related expenses. We hope to be able to maintain this trend going forward. In addition, we recognized a one-time, favorable tax credit during the quarter which reduced our effective tax rate to 37%. We expect the tax rate to return closer to the 38% level going forward," Campbell noted. In addition, the third quarter 1997 results include non-recurring charges of $1.6 million after tax related to severance costs, and also reflect the benefit of adjustments to previously established reserves of a similar amount.
