PREFORMED LINE PRODUCTS ANNOUNCES FINANCIAL RESULTS

FOR THE QUARTER ENDED MARCH 31, 2010

Mayfield Village, Ohio, April 30, 2010 – Preformed Line Products Company (Nasdaq:PLPC) today reported financial results for the first quarter ended March 31, 2010.

Net income for the quarter ended March 31, 2010 was $1,132,000, or $.21 per diluted share, compared to $2,722,000, or $.51 per diluted share, for the comparable period in 2009.

Net sales for the first quarter of 2010 increased 17% to $68,908,000 compared to $58,694,000 in the first quarter of 2009.

Currency translation had a positive impact on sales and net income for the quarter of $6.9 million and $.4 million, respectively.

Rob Ruhlman, Chairman and Chief Executive Officer, said, “Our overall results for the current quarter were disappointing given the 17% increase in sales.  Increases in our raw material costs and integration expenses related to the acquisition of Dulmison in December 2009 contributed to the decline in our operating profit.   The improvement in sales as a result of adding Dulmison was offset by the continuing faltering economy in Europe as well as the ongoing economic challenges in the U.S.  If we have an uptick in sales in the second quarter, there should be a corresponding improvement in leveraging our expenses.”
