FRANKLIN, TN, Tuesday, June 15, 2010—CLARCOR Inc. (NYSE:  CLC) reported its financial results for the second quarter ended May 29, 2010.  Operating profit increased 44%, and net earnings rose 42% from the second quarter of 2009.  Diluted earnings per share increased 42% to $0.47 in the second quarter of 2010 from $0.33 in the second quarter of 2009.  The impact of foreign currency exchange rates positively influenced the Company’s net sales by $3.6 million and its operating profit by $0.9 million compared to the second quarter of 2009.

Norm Johnson, CLARCOR’s Chairman and Chief Executive Officer, said, “Our second quarter operating results were strong.  Sales increased 12% from last year and were only 3% below sales in the second quarter of 2008 prior to the recession.  The sales increase from prior year drove the 44% increase in operating profit and improved our operating margin to 14.0% from 11.0% in the last year’s second quarter.  In fact, our operating profit and margin were comparable to operating profit of $37.5 million and margin of 14.0% from the second quarter of 2008.  This strong performance demonstrates our continued sales recovery from the recession and reflects the benefits of the various cost initiatives we put in place last year including our restructuring efforts at our HVAC filter operations.  Our improved cost structure positions us well to fully capitalize on the profit potential of our future growth opportunities both domestically and abroad.

“Our sales did not decline in 2009 as significantly as many other industrial companies, so our top-line rebound will not be as pronounced.  Our revenue stream is somewhat sheltered from extreme cyclicality due to our 80% aftermarket sales concentration and our geographic and end-market diversification.  Because of this and our strong balance sheet, we have been able to continue to focus on growth as we made the conscious decision not to reduce investment in sales efforts, research or product development.  We are experiencing the positive impact of this decision as we introduce new products and enter new markets including filtration solutions for the animal husbandry and mobile telecommunication markets.

“On the strength of increased sales and the related higher absorption of fixed manufacturing costs, our 32.9% gross margin in the second quarter of 2010 exceeded our gross margin of 30.3% in the second quarter last year.  More impressive, our gross margin in this year’s second quarter exceeded our 32.0% gross margin from the second quarter of 2008 despite a 3% reduction in sales.  This gross margin improvement is a strong indicator of our continuing success in eliminating cost and improving the efficiency of our manufacturing processes.

“All of our business segments contributed to our success in the second quarter.  Operating profit at each segment climbed significantly from last year.  The increase at our Engine/Mobile Filtration segment was the result of higher sales of heavy-duty engine filters both in the U.S. and internationally.  The increase at our Industrial/Environmental Filtration segment was driven by lower costs at our HVAC filter operations and incremental sales to oil drilling, aerospace and other industrial markets, and the increase at our Packaging segment was the result of higher sales primarily to the smokeless tobacco industry.

Engine/Mobile Filtration Segment

“Net sales at our Engine/Mobile Filtration segment increased $21.1 million or 23% compared to the second quarter of 2009.  This improvement was driven in large part by higher heavy-duty engine filter sales both domestically and internationally.  Sales of aftermarket heavy-duty engine filters in North America increased significantly in the second quarter of 2010 partially driven by an increase in heavy-duty truck tonnage in the U.S. compared to the second quarter of 2009.  Sales in China increased over 40% from the second quarter of 2009 as a result of incremental sales to both new and existing customers.  Despite the European macroeconomic issues, heavy-duty engine filter sales to Europe markets actually increased from last year.  In addition, U.S. sales of railroad filtration products increased as additional locomotives were taken from storage with the continued strengthening of U.S. rail activity.

“Operating profit at our Engine/Mobile Filtration segment increased $5.2 million or 28% from the second quarter of 2009.  Operating margin increased to 20.8% in the second quarter of 2010 from 20.0% in the second quarter last year.  The improvement in operating profit and margin from 2009 is primarily attributable to the higher year-over-year heavy-duty engine filter and railroad filtration product sales.

Industrial/Environmental Filtration Segment

“Net sales at our Industrial/Environmental Filtration segment declined $2.3 million or 2% to $117.6 million in the second quarter of 2010.  This reduction includes a $5.3 million reduction in HVAC filter sales to the 3M Company (“3M”) as compared to the second quarter of 2009.  3M informed us in the third quarter of 2009 that it would no longer be purchasing HVAC filters from us.  Excluding this reduction in sales to 3M, sales in this segment increased $3.0 million or 3% from the second quarter of 2009.  As a result of the benefits of our restructuring program at our HVAC filter operations, operating profit in the Industrial/Environmental Filtration segment increased $4.5 million or 77% to $10.4 million in the second quarter.  Operating margin increased to 8.8% in the second quarter of 2010 from 4.9% in the second quarter of 2009 and 4.2% from the first quarter of 2010.

“Despite HVAC filter sales being lower in the second quarter of 2010 driven by the 3M reduction, operating profit at our HVAC filter operations improved $2.0 million from the second quarter of 2009.  This improvement was the result of our restructuring efforts, including the elimination of fixed costs from the closure of several manufacturing facilities, and the reduction of material costs from commodity pricing and continued manufacturing efficiencies.  We anticipate that operating performance at our HVAC filter operations will continue to strengthen in 2010 as we benefit from the changes in our cost structure, and we leverage our expected sales growth from existing and new markets in the second half of the year.

“Sales of filters to oil drilling, aerospace and other industrial markets improved significantly in the second quarter of 2010 compared to the second quarter of 2009 and drove an increase in operating profit in these markets.  Based upon recent strong order activity, we anticipate that the year-over-year growth in these markets will continue throughout 2010, and we expect full year sales growth between 18% and 20%.

“Our largest concentration of European sales is to the aviation and wastewater markets.  Global sales to these markets declined approximately 15% from the second quarter of 2009 driven by a 20% decline in European sales.  Sales to the U.S. were essentially flat compared to last year’s second quarter.  Although we expect European sales to continue to be lower than 2009 levels for the remainder of 2010, this decline should be offset by an increase in U.S. sales.  Overall, we anticipate full year 2010 global sales to the aviation and wastewater markets to be down less than 5% from last year.

“We expect that our overall natural gas vessel and element sales for the full year 2010 will grow between 7.0% and 9.0% from 2009, though sales to this market were down in the second quarter and first six months of 2010 compared with 2009.  Despite lower sales, operating profit from the natural gas market was consistent with 2009 due to lower steel prices, a higher mix of aftermarket element sales, which command a higher margin, and a reduction in selling and administrative expenses.  We anticipate the sale of natural gas vessels will be higher in the second half of 2010.  We have experienced a steady increase in our vessel sale backlog since September 2009, a trend which we believe should continue heading into the fourth quarter of 2010 due to natural gas finds during 2009, both in the U.S. and overseas.  In addition, our emphasis on building our natural gas filtration aftermarket business is gaining momentum and should grow faster than our natural gas vessel business.

Packaging Segment

“Net sales at our Packaging segment increased $9.7 million or 56% to $26.9 million in the second quarter of 2010.  This increase includes a one-time, no margin $4.6 million equipment sale to one of our customers.  Excluding this equipment sale, net sales increased by $5.1 million or 29%.  This increase was primarily driven by additional sales of smokeless tobacco packaging.  Operating profit in the second quarter of 2010 rose from 2009 primarily due to the incremental profit from this increase in sales.

Cash Flow and Balance Sheet

“Our financial position continues to be solid, and our cash flow remains strong.  Cash flow from operating activities, excluding changes in our short-term investments, decreased to $37.8 million in the first six months of 2010 from $52.5 million in the same period last year.  This $14.7 million reduction was the result of an additional $26.5 million outflow for working capital requirements to support our elevated sales levels partially offset by higher net earnings of $12.9 million.  In the first six months of 2010, we used cash of $35.0 million to pay down our line of credit in full.  The strength of our balance sheet, including our $250.0 million undrawn line of credit and cash of $75.7 million, provides us with the valuable financial flexibility to fund internal growth opportunities, consider potential acquisitions and repurchase shares.

Outlook

“We continue to be pleased with our operating results in the first six months of 2010.  Sales and operating profit improvements from 2009 are quite significant as we have experienced a positive turning point in sales in most of our product markets.  More impressive, however, are the comparisons with the second quarter of 2008 prior to the recession.  Despite lower sales, operating profit and margin in the second quarter of 2010 were comparable to the second quarter of 2008 on the strength of various cost initiatives including the restructuring of our HVAC filter operations.

“While we remain cautious due to tenuous global economic conditions, we are increasing our 2010 guidance for diluted earnings per share to be in the range of $1.70 to $1.85 up from our previous guidance of $1.55 to $1.70.  Reaching the high-end of our guidance will require the economy to continue to improve in the second half of the year.  We are aware that there is concern that economic growth could stagnate for the remainder of the year.  If the economy does indeed slow down, reaching the high-end of our guidance would be a challenge.

The ranges of expected annual 2010 sales growth rates from 2009 and expected 2010 operating margins by segment and in total are as follows:

		2010 Estimated Sales Growth		2010 Estimated Operating Margin
Engine/Mobile Filtration		14% - 16%		20.0% - 21.0%
Industrial/Environmental Filtration		4% - 5%		8.0% - 9.0%
Packaging		19% - 20%		7.5% - 8.5%
CLARCOR		9% - 11%		13.0% - 14.0%

“We expect a full year effective tax rate from 33% to 34%, 2010 cash flow from operating activities (excluding changes in short-term investments) from $90.0 million to $105.0 million and 2010 capital expenditures from $30.0 million to $35.0 million.

CLARCOR will be holding a conference call to discuss the first quarter results at 10:00 a.m. CDT on June 16, 2010.
