ENCORE WIRE REPORTS FIRST QUARTER RESULTS

MCKINNEY, TX — Encore Wire Corporation (NASDAQ Global Select: WIRE) today announced results for the first quarter of 2010.

Net sales for the quarter ended March 31, 2010 were $175.2 million compared to $144.5 million during the first quarter of 2009. Net loss for the first quarter of 2010 was $2.5 million versus net income of $4.6 million in the first quarter of 2009. Fully diluted net loss per common share was $0.11 in the first quarter of 2010 versus earnings of $0.20 in the first quarter of 2009. Unit volumes, measured in pounds of copper contained in the wire sold during the period declined 30.6% in the first quarter of 2010 versus the first quarter of 2009. However, the spread between the cost of a pound of copper purchased and the price of a pound of copper sold increased by 12.3%. The 2010 first quarter results include a $2.6 million dollar pre-tax charge associated with the early retirement of long-term debt that the Company paid off in January.

On a sequential quarter comparison, net sales for the first quarter of 2010 were $175.2 million versus $177.1 million during the fourth quarter of 2009. Net loss for the first quarter of 2010 was $2.5 million versus a $1.9 million net loss in the fourth quarter of 2009. Fully diluted net loss per common share was $0.11 in the first quarter of 2010 versus a $0.08 net loss in the fourth quarter of 2009. Unit volumes declined 13.3% in the first quarter of 2010 versus the fourth quarter of 2009. However, the spread between the cost of a pound of copper purchased and the price of a pound of copper sold increased by 28.6%.

Commenting on the results, Daniel L. Jones, President and Chief Executive Officer of Encore Wire Corporation, said, “Unit volume decreases caused by the drop in construction activity continue to create turmoil in our industry. During the quarter, a competitor exited the market by selling out to another competitor. Despite the continued volume decreases, there were positive developments, including the increase in “spreads” during the past quarter. The spread between the price of wire sold and the cost of raw copper is a key metric in this industry and a key driver of the level of profitability. With our low cost structure, we have strong upside leverage when the spread expands. On a sequential quarter basis, the average cost of copper purchased increased by 10.7%, while the average price of wire sold increased by 14.1%, increasing the spread by 28.6%. Our pre-tax loss of $4.1 million ($2.5 million net of income taxes) includes a one-time pre-tax charge of $2.6 million ($1.7 million net of income taxes) associated with the debt retirement we executed in January. This positive change in sequential quarterly earnings occurred despite the 13.3% decrease in unit volume sold. We continue to strive to lead or follow industry price increases to achieve profit growth.

We produced these results in this difficult environment due to our low cost business model and aggressive cost cutting in all facets of our operation. We believe our superior order fill rates continue to enhance our competitive position, as our electrical distributor customers are holding lean inventories in the field.

We continue to maintain our strong balance sheet. We paid off our long-term debt and our $150 million revolving line of credit has a zero balance. In addition, we had $130.4 million in cash as of March 31, 2010. Our bank covenants were amended in the quarter to take current economic conditions into account. We also declared our fourteenth consecutive quarterly cash dividend during the first quarter of 2010.

With our exceptionally strong balance sheet, we have the capability to approach the future confidently. Our low cost structure and strong balance sheet have enabled us to withstand tough periods in the past, and we believe we will emerge stronger than most when market conditions improve. We thank our employees and associates for their tremendous efforts and our stockholders for their continued support.”
