ENCORE WIRE REPORTS SECOND QUARTER RESULTS

MCKINNEY, TX - Encore Wire Corporation (NASDAQ Global Select: WIRE) today announced results for the second quarter and six months ended June 30, 2014.

Net sales for the second quarter ended June 30, 2014 were $307.1 million compared to $289.5 million during the second quarter of 2013. Copper unit volume, measured in pounds of copper contained in the wire sold, increased 10.0% in the second quarter of 2014 versus the second quarter of 2013, accounting for most of the increase in net sales dollars. Aluminum building wire sales also contributed to the increased sales, constituting 8.9% of net sales dollars for the second quarter of 2014 versus 6.6% in the second quarter of 2013. The average selling price of wire per copper pound sold dropped 6.0% in the second quarter of 2014 versus the second quarter of 2013, somewhat offsetting the increase in sales dollars. Net income for the second quarter of 2014 was $10.2 million versus $15.5 million in the second quarter of 2013. Fully diluted net earnings per common share were $0.49 in the second quarter of 2014 versus $0.75 in the second quarter of 2013.

Net sales for the six months ended June 30, 2014 were $584.3 million compared to $554.8 million during the same period in 2013. Copper unit volume in the six months ended June 30, 2014 increased 9.6% versus the same period in 2013, offset by a 6.2% drop in average sales prices. Aluminum building wire sales contributed to the increased sales, constituting 8.4% of net sales dollars for the six months ended June 30, 2014 versus 6.1% in the six months ended June 30, 2013. Net income for the six months ended June 30, 2014 was $21.0 million versus $21.9 million in the same period in 2013. Fully diluted net earnings per common share were $1.01 for the six months ended June 30, 2014 versus $1.06 in the same period in 2013.

On a sequential quarter comparison, net sales for the second quarter of 2014 were $307.1 million versus $277.2 million during the first quarter of 2014. Copper wire unit volume increased 14.9% on a sequential quarter comparison, offset somewhat by a 4.6% decrease in average sales prices. Aluminum building wire sales also contributed to the increased sales, constituting 8.9% of net sales dollars for the second quarter of 2014 versus 7.9% in the first quarter of 2014. Net income for the second quarter of 2014 was $10.2 million versus $10.9 million in the first quarter of 2014. Fully diluted net income per common share was $0.49 in the second quarter of 2014 versus $0.52 in the first quarter of 2014.

Commenting on the results, Daniel L. Jones, President and Chief Executive Officer of Encore Wire Corporation, said, “Continuing the positive trend we saw developing throughout last year, the second quarter was encouraging to us. Unit volumes were up in all building wire products. We believe our expansion of product offerings to our existing customer base over the last several years has been critical to maintaining and perhaps boosting our market share, as our capital expenditures help to drive increased sales. As we have repeatedly noted, one of the key metrics to our earnings is the “spread” between the price of copper wire sold and the cost of raw copper purchased in any given period. That spread decreased 9.9% in the second quarter of 2014 versus the second quarter of 2013, while our copper unit volume shipped in the second quarter of 2014 increased 10.0% versus the second quarter of 2013. The copper spread contracted as the average price of copper purchased fell 4.4% in the second quarter of 2014 versus the second quarter of 2013, but the average selling price of wire sold fell 6.0%, as a result of

slightly unfavorable pricing discipline in the industry. That same trend was evident on a sequential quarterly comparison, as copper unit sales increased 14.9% with a 6.1% decrease in spreads. We believe that certain competitors cut prices in the second quarter of 2014 to try to “remain competitive” with our superior service levels. Along with the continued success of our aluminum building wire launch, the increase in copper unit volumes drove earnings per share in the second quarter. The aluminum building wire products grew to 8.9% of net sales in the quarter, driven by a unit sales increase of 28.9% on a sequential quarter basis. We continue to strive to lead or follow industry price increases to achieve profit growth. We produced these results due to our low cost business model and aggressive cost control in all facets of our operations. 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.

Our balance sheet is very strong. We have no long term debt, and our revolving line of credit is paid down to zero. In addition, we had $19.1 million in cash as of June 30, 2014. We also declared another cash dividend during the quarter. Our low cost structure and strong balance sheet have enabled us to withstand difficult periods in the past, and we believe that this strategy will serve us well going forward. We thank our employees and associates for their outstanding effort and our shareholders for their continued support.”
