First Quarter 2008 Operating Review

     FRANKLIN, TN, Wednesday, March 19, 2008—CLARCOR Inc. (NYSE: CLC) today reported results for the first quarter ended March 1, 2008. Sales in the first quarter of 2008 rose by $41 million, a 19% increase compared to the first quarter of 2007. Operating profit increased by 18% compared to the same quarter in 2007. Foreign currency fluctuations favorably impacted sales and operating profit by $6 million and $1 million, respectively, for the most recent quarter.

Net earnings declined by 1% and diluted earnings per share was unchanged from the first quarter in 2008 compared to the first quarter due to a $2.4 million charge to interest expense this quarter. During the quarter we entered into an interest rate swap to fix the interest rate we will pay for the next two years on borrowings of $100 million. We recorded a mark to market adjustment for this swap in the first quarter for $2.4 million that will reverse and reduce interest expense for the next seven quarters. The actual impact of this charge will have no effect on net earnings or earnings per share over the two year period. In addition, we will benefit from reducing the impact of interest rate fluctuations for the next two years. Excluding this charge, net earnings would have increased by 9% and earnings per share would have been $0.35 for the quarter.

Norm Johnson, CLARCOR’s Chairman and Chief Executive Officer, said, “We are very pleased with our first quarter operating results. Excluding the Peco acquisition, organic sales growth was 7% and operating profit growth was 17% compared to last year.
Despite a clearly slowing U.S. economy, our first quarter performance was strong and was primarily driven by the following:

• Double-digit sales growth in our non-U.S. heavy-duty engine filter business, both in local currency and in U.S. dollars.

• Double-digit sales growth in our air quality and dust collector business, both domestically and overseas.

• Continuing strong world-wide demand for our oil and gas filter products.

• Significant improvement this quarter in our packaging business.

“Though not growing at the same pace, most of our other businesses also reported continuing sales growth, including domestic heavy-duty engine and railroad filtration, fiber and resin filtration, and aviation fuel and aerospace filtration products. With increasing sales, we were able to leverage our cost structure resulting in even faster growth in operating profit. We are also pleased that operating margins in the first quarter of 2008 improved in each of our business segments from 2007 even after an additional $27 million in sales from Peco at very little operating profit. Excluding the Peco acquisition, operating margins rose to 12.3% for the quarter from 11.3% in the first quarter of 2007.

“I think this quarter’s results demonstrate clearly the benefit from the many investments we have made over the last 15 years to expand our portfolio of filtration companies. Historically, CLARCOR’s growth was driven by our domestic heavy-duty engine and railroad business, supported by our aviation fuel and aerospace product lines. This quarter’s growth was driven by our oil and gas businesses, our non-U.S. businesses and our air filtration system products. Our diversification into many different, though complementary, filtration lines has resulted in an operation with increasingly stable sales and profits. We have maintained our focus on the filtration aftermarket which provides a strong base of recurring revenues. In addition, the breadth of the filtration product lines we sell increases our ability to grow as almost any filtration opportunity, whether from the development of additional product lines or from a possible acquisition, will fit within CLARCOR.

“The acquisition of Peco in the first quarter of fiscal 2008 added $27 million to sales. Peco contributed approximately $200,000 to operating profit in the first quarter of 2008 due to the costs of the transition and the impact of purchase accounting adjustments. One of these adjustments, which will affect only this quarter, was a one-time increase in cost of sales of $1.5 million in the first quarter arising from manufacturing profit in inventory at the date of the acquisition. Based upon the current backlog and product demand, we expect Peco’s sales, operating profit and operating margin for fiscal 2008, excluding purchase accounting adjustments, to exceed what it had achieved as a private company in its last fiscal year prior to the acquisition. For its fiscal year ended May 2007, Peco reported sales of $102 million and operating profit of $12 million. We continue to expect that Peco will be accretive to diluted earnings per share this year.

“The Peco acquisition transition is progressing well. Demand for Peco’s vessels and filter elements for gas transmission facilities is very strong and the backlog continues to increase. Demand is coming from both U.S. and overseas customers, particularly throughout Asia. We have had many meetings between our Facet and Peco operations and see numerous sales opportunities, including potential sales in industrial and waste water filtration that we would otherwise be unable to achieve. We believe that the technical and distribution synergies from combining Peco and Facet will be significant. For example, we are working to develop enhanced Peco oil and gas filters manufactured using our nanofiber technology. We are also working to utilize Peco’s proprietary Peach^® filter media to produce a new line of heavy-duty engine fuel filters for our Engine/Mobile businesses.

“The restructuring of our CLC Air business is proceeding. We believe that the decline in sales that we experienced last year is largely over. Sales in the first quarter of 2008 were slightly below the same quarter in 2007. As we have noted, over the first six months of last year we eliminated several unprofitable customers so we had expected very little sales growth this quarter. We incurred an operating loss at CLC Air this quarter, but this was also expected. For the rest of 2008, we expect significantly improved performance at CLC Air. The equipment delays we encountered last year are largely over and we expect to see improving productivity in our manufacturing operations leading to a substantially lower cost structure, primarily in reduced labor and freight costs, as the year progresses. So far we have spent over $10 million for new equipment and expect to purchase an additional $4 to $5 million over the rest of this year.

“We have not changed our expectations regarding the CLC Air restructuring. We still expect operating profit to improve by approximately $10 million from 2007; to achieve a $14 million improvement in operating profit by the end of 2009; and to continue to drive towards our ultimate goal of a 10% operating margin for this business.

“Our Packaging segment improved significantly from the same period last year which was an unusually difficult quarter. The improvement from last year is due to increased sales of decorated metal and plastic packaging to confectionary, spice and tobacco companies. I need to point out though that the first quarter is normally this segment’s slowest and not necessarily indicative of performance during the next three quarters. However, we are very optimistic that 2008 will be a good year for J.L. Clark and more reflective of its results in 2005 and 2006 than its 2007 results.

“Other expense increased this quarter primarily due to increased interest expense related to the Peco acquisition and the $2.4 million interest charge related to an interest rate swap we entered into during the quarter. The $2.4 million charge will reverse over the next two years and reduce interest expense by the same amount. Early in the quarter, we renegotiated our borrowing arrangements with a consortium of banks, raising our line of credit from $165 million to $250 million while also lowering the interest rate we are charged on any outstanding borrowings.

“Our tax rate in the first quarter at 32.8% was slightly lower than will be the case for the rest of 2008. In the first quarter, we recorded a $400,000 tax benefit related to a refund we received in one of our overseas subsidiaries arising from changes in certain tax regulations.

“Cash flows from operating activities increased by over 9% this quarter compared to last year’s quarter. Cash dividends increased by nearly 11%. During the quarter, we repurchased 1,000,000 shares of our common stock at an average price of $37.26 per share. Share repurchases in future quarters will depend on cash availability, acquisition opportunities and the market price of our common stock. Capital expenditures this year are expected to be approximately $40 million to $50

million compared to $37 million in 2007. Much of this expenditure is due to the HVAC restructuring program, expansion programs for new products and production lines, and new warehouse and inventory management systems.

“We still expect that 2008 earnings per share will be in the $1.85 to $2.05 range. This estimate is unchanged from our estimate in January. We are concerned regarding the strength of the U.S. economy for the rest of 2008, but we still expect that CLARCOR will record higher sales and higher net earnings than in 2007 and that 2008 will be our 16^th consecutive record year.”
