Second Quarter and Six Months 2007 Operating Review

FRANKLIN, TN, June 19, 2007 — CLARCOR Inc. (NYSE: CLC) reported today that second quarter 2007 net earnings increased by 25% and diluted earnings per share increased by 28% compared to the same quarter in 2006. Sales for the second quarter of 2007 increased by 4% and operating profit increased by 20% compared to the same period in 2006. Overall, operating margins improved to 13.4% for the 2007 second quarter compared to 11.5% in last year’s second quarter.

In the second quarter of 2006, CLARCOR recorded a $3 million bad debt expense charge to operating profit, or $0.04 per diluted share, which did not recur in this year’s second quarter. If that charge had not been recorded in 2006, the improvement in second quarter operating profit and net earnings from 2006 to 2007 would have been 8% and 12%, respectively. Even excluding the $3 million charge, operating margins improved this quarter by over 50 basis points compared to last year’s second quarter.

Norm Johnson, CLARCOR’s Chairman and Chief Executive Officer, said, “We had a very good second quarter and believe that the rest of this year will show further improvement in both sales and operating profit compared to last year’s results. Particularly strong results were shown by our international Engine/Mobile segment operations. Sales grew 30% during the 2007 second quarter including the Sinfa acquisition made earlier this year and 19% excluding the acquisition. Likewise, in our Industrial/Environmental segment businesses, European sales grew by 26% from last year.

Even though we benefited from the weakness during the quarter of the U.S. dollar, on a local currency basis our European sales grew by 13% and our Asian sales by over 25%.

“Engine/Mobile Filtration sales rose by 7% from last year’s second quarter and 5% excluding the Sinfa acquisition. Operating profit improved by 9%. Heavy-duty engine filter sales grew at a faster rate in the second quarter compared to earlier in 2007 as over-the-road truck traffic was stronger in the second quarter of this year than it was in the first quarter. Filter sales for railroad locomotive applications fell slightly compared to last year. Operating margins in the current quarter improved to 22.5% compared to 22.1% last year. We expect sales growth in our Engine/Mobile Filtration segment to be stronger in the second half of 2007. This is based on current order patterns and an expectation that domestic freight tonnage movement will gradually increase, both by truck and by rail, as the year progresses.

“Sales in our Industrial/Environmental Filtration segment rose 2% in the second quarter of 2007 compared to the same period in 2006. However, this small increase obscures significant differences this quarter by end markets. Sales to industrial filter end markets grew by 27% while sales to environmental end markets declined by 10%. Sales to industrial end markets were strong in most of our product lines, including oil and gas, aerospace, aviation fuel and general industrial liquid filters. Operating margins in our industrial end market grew to nearly 15% during the quarter.

“There were several reasons for the decline in sales to environmental end markets from last year’s second quarter. First, we terminated a $10 million contract with a customer in the second quarter 2006, but still had some second quarter 2006 sales from this customer that we did not have this year. Second, we are in the first year of a three-year program to restructure our HVAC filter operations. One of the steps in this program is to remove lower margin customers, and that happened this quarter. Also, HVAC filter sales to automotive manufacturers and lower-tier automotive parts suppliers continue to slowly decline. Offsetting this, however, is continual progress at selling our Total Filtration program to non-automotive customers. Recent successes include new regional and national programs with a number of non-automotive Fortune 500 companies. Sales for 2007 to environmental customers will be lower than in 2006, but we do expect an improvement in operating margins as our HVAC restructuring program accelerates.

“The goal of our HVAC restructuring program is to improve operating profit. By the end of 2009 we expect an improvement in our operating profit run rate of $14 million annually compared to 2006 operating profit for this market. There are many initiatives in this program, but the improvement in operating margins is anticipated to come primarily from regionalizing our manufacturing facilities to substantially reduce our freight costs and to better service our customers, and a significant investment in automated manufacturing equipment to increase manufacturing productivity. Over the three-year period we plan to spend approximately $23 million in new equipment under this program. This is in addition to our normal levels of capital spending for the HVAC market. We expect a small improvement in margins later this year and a much greater improvement in 2008 and 2009.

“Our Packaging segment had a slow second quarter. Sales declined by 6% this quarter compared to last year, and operating profit decreased by approximately $600 thousand. Operating margins decreased to 8% this quarter from 10% in the second quarter last year, but we expect higher operating margins for the rest of 2007. The sales decline was caused by slower growth in our customers’ sales of their products resulting in reduced shipments to them. This was particularly true in the confectionary markets where some of our customers saw a slower sales buildup in their new product introductions than they had anticipated. We do not expect to recover the entire sales shortfall from the first half of 2007 during the rest of this year, but we do expect improved margins based on current cost reduction initiatives and greater plant efficiencies.

“There was little change in other income compared to last year’s second quarter. Our tax rate was approximately 33.2% for the quarter, which was somewhat higher than it was in the first quarter of 2007. We expect the rate to be approximately 34.0% to 35.0% for the next two quarters.

“Currency fluctuations had a larger impact on sales and operating profit this quarter than we normally experience. Currency fluctuations increased dollar-denominated sales by $4 million and dollar-denominated operating profit by $500 thousand.

“Capital expenditures were $18 million for the six-month period just ended compared to $7 million in the six-month period a year earlier. We expect capital spending will increase during the second half of the year, partly due to our HVAC restructuring program, and is expected to total $40 million to $45 million for 2007 compared to $18 million in 2006. As always, we are continuing to invest in new technologies, new media and new product development. Later this year, we will begin manufacturing nanofiber embedded media which we will initially use for dust collector cartridges. We have also begun intensive research in using nanofiber media in filtration applications that have never before used this type of media as well as experimentation on new approaches in applying nanofibers to different types of filtration media.

“Cash flow continues to be strong. Cash from operations increased to $81 million in the 2007 six-month period from $19 million last year. We repurchased nearly $50 million of our common stock this quarter and nearly $80 million during the last twelve months. We expect to continue to repurchase our common stock depending on the current stock price and interest rates. The average stock repurchase price during the second quarter was $31.83 per share.

“Based on our first half results and current backlog, we expect our 2007 sales to grow by approximately 6% from 2006. We also expect diluted earnings per share for 2007 to be from $1.72 to $1.80, and the midpoint of this range would be an 11% increase over 2006. We expect that CLARCOR will have a record 2007 and post its 15^th consecutive year of increased sales and earnings.”
