DES PLAINES, IL – Littelfuse has revised its guidance for the second quarter and full year of 2007.

Sales for the second quarter, which previously were expected to be up 2 percent to 5 percent sequentially, are now expected to be similar to the first quarter of 2007. First quarter 2007 sales were $131.8 million.

Diluted earnings per share for the second quarter, which previously were expected to be in the range of 48 cents to 52 cents, are now expected to be approximately 40 cents excluding an estimated gain of 22 cents per diluted share on the sale of excess land in Ireland. Diluted earnings per share on a GAAP basis are expected to be approximately 62 cents.

“Our electronic sales have not ramped up as expected during the quarter, due to softness in the telecom segment and lingering effects of the inventory correction,” said Gordon Hunter, chief executive officer. “Margins will also not show the expected improvement in the quarter due primarily to lower-than-expected plant utilization. Although electronic sales for the second quarter will be below our previous guidance, we have seen order rates improve in the last several weeks, and we still expect third quarter sales to increase sequentially from the second quarter,” added Hunter.

Previous full year 2007 guidance called for a 3 to 5 percent sales increase over 2006 and an earnings goal of $2 per diluted share excluding restructuring charges.

The revised guidance for 2007 is as follows:

• Sales at similar levels to 2006. Sales for 2006 were $534.9 million.

• Diluted earnings per share of $1.65 to $1.75, excluding restructuring charges and the Ireland gain but including ongoing costs related to the previously-announced manufacturing transfers such as retention bonuses, equipment move costs and accelerated depreciation on legacy assets. These transfer costs are being booked as period expense and are currently running at approximately $1 million per quarter pre-tax for an after-tax earnings per share impact of 3 cents per quarter.

“Although the prospect of a flat sales year in 2007 is disappointing, our major cost reduction projects and new product development programs remain on track,” said Hunter. “As a result, we are still confident of achieving our 15 percent operating margin target by the end of 2009.”
