ENCORE WIRE REPORTS THIRD QUARTER RESULTS

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

Net sales for the third quarter ended September 30, 2014 were $297.4 million compared to $309.9 million during the third quarter of 2013. Copper unit volume, measured in pounds of copper contained in the wire sold, decreased 5.7% in the third quarter of 2014 versus the third quarter of 2013, accounting for most of the decrease in net sales dollars. Aluminum building wire sales somewhat offset the decreased copper sales, constituting 9.4% of net sales dollars for the third quarter of 2014 versus 7.2% in the third quarter of 2013. Aluminum unit volume was up 28.4% in the third quarter of 2014 versus the third quarter of 2013. The average selling price of wire per copper pound sold dropped 0.7% in the third quarter of 2014 versus the third quarter of 2013. Sales prices declined primarily due to lower copper prices, which declined 1.8% versus the third quarter of 2013. Net income for the third quarter of 2014 was $11.1 million versus $13.8 million in the third quarter of 2013. Fully diluted net earnings per common share were $0.53 in the third quarter of 2014 versus $0.66 in the third quarter of 2013.

Net sales for the nine months ended September 30, 2014 were $881.6 million compared to $864.7 million during the same period in 2013. Increased unit volumes of building wire sold in the first nine months of 2014 versus the first nine months of 2013 accounted for the increase in net sales dollars. Unit volume, measured in copper pounds contained in the wire sold increased 4.0% in the first nine months of 2014 versus the first nine months of 2013. The volume increase was offset somewhat by a 4.3% decrease in the average selling price per copper pound sold in the first three quarters of 2014 versus the same period in 2013. Sales prices declined primarily due to lower copper prices, which declined 4.9% in the first three quarters of 2014 versus the first three quarters of 2013. Aluminum unit volume increased 43.6% in the first nine months of 2014 versus the first nine months of 2013. Net income for the nine months ended September 30, 2014 was $32.1 million versus $35.7 million in the same period in 2013. Fully diluted net earnings per common share were $1.54 for the nine months ended September 30, 2014 versus $1.72 in the same period in 2013.

On a sequential quarter comparison, net sales for the third quarter of 2014 were $297.4 million versus $307.1 million during the second quarter of 2014. Unit volume of copper building wire accounted for the majority of the decrease, dropping 7.4% on a sequential quarter comparison. Net income for the third quarter of 2014 increased to $11.1 million versus $10.2 million in the second quarter of 2014. Fully diluted net income per common share was $0.53 in the third quarter of 2014 versus $0.49 in the second quarter of 2014.

Commenting on the results, Daniel L. Jones, President and Chief Executive Officer of Encore Wire Corporation, said, “The third quarter was good from both a volume and margin perspective. Aluminum unit volumes were up strongly in the quarter and the nine month periods as we continue to grow that portion of our building wire business. Copper wire units are up on a year to date basis. The overall construction and building wire markets appear to be doing okay this year but not showing any significant improvement over last year. Anecdotal information confirms our belief that we are outperforming the industry in volume growth. Our third quarter copper wire unit volumes are near the average of the first two quarters. 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 increased 2.1% in the third quarter

of 2014 versus the third quarter of 2013, and 9.6% on a sequential quarter comparison. The copper spread expanded 9.6% as the average price of copper purchased rose 1.8% in the third quarter of 2014 versus the second quarter of 2014, but the average selling price of wire sold rose 3.9%, as a result of somewhat improved pricing discipline in the industry. The aluminum building wire products grew to 9.4% of net sales in the quarter, driven by a unit sales increase of 28.4% in the third quarter of 2014 versus the third quarter of 2013. We continue to strive to lead and support industry price increases in an effort to maintain and increase margins. 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. As orders come in from electrical contractors, the distributors can count on our order fill rates to ensure quick deliveries from coast to coast. We have been able to accomplish this despite holding what are historically lean inventories for us.

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 $38.8 million in cash at the end of the quarter. 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 are continuing to prove valuable now. We thank our employees and associates for their outstanding effort and our shareholders for their continued support.”
