Mayfield Village, Ohio, August 5, 2010 – Preformed Line Products Company (Nasdaq:  PLPC) today reported financial results for the second quarter and the first six months of 2010.

Net income for the quarter ended June 30, 2010 increased 70% to $6,096,000, or $1.13 per diluted share, compared to $3,584,000 or $.68 per diluted share, for the comparable period in 2009.

Net sales in the second quarter of 2010 were $82,137,000, an increase of 38% from sales of $59,568,000 in the second quarter of 2009.

Net income for the six months ended June 30, 2010 increased 15% to $7,228,000, or $1.34 per diluted share, compared to $6,306,000, or $1.19 per diluted share for the comparable period in 2009.  Net sales increased 28% to $151,045,000 for the first six months of 2010 compared to $118,262,000 in the first six months of 2009.

Currency exchange rates favorably impacted sales by $3,661,000 for the quarter and $10,597,000 for the first six months of 2010, while the favorable impact on net income was $245,000 for the quarter and $599,000 for the first six months of 2010.

Rob Ruhlman, Chairman and Chief Executive Officer, said, “We had a strong second quarter enabling us to overcome the disappointing results of the first quarter.  The integration of the Dulmison product line acquired in December of last year continues to proceed smoothly.  Although we have additional work to do in merging the Dulmison operations with our existing operations, I am happy with the cooperation and progress made between the two operations.  This acquisition certainly contributed to our second quarter growth but I am particularly impressed with the performance and success of our legacy operations in the face of an ongoing difficult world economic environment.  We continue to feel the pressure of higher raw material costs and we are countering by improving our production efficiencies and capitalizing on the strength of our geographical diversity.”
