Ply Gem Results

Key Highlights Second Quarter Results

Second Quarter 2014 Highlights

• Net sales increase of 11.2% was due to the acquisitions of Gienow and Mitten which occurred in the second quarter of 2013, a slight 3.5% increase in U.S. single-family housing starts and an increase in average selling prices in both of our business segments.

• Gross margin expansion of 120 basis points driven by increased average selling prices and operating efficiency improvement in our U.S. windows business partially offset by integration and customer transition expenses related to the consolidation of our Western Canadian windows business.

End Market Exposure (*)

• 7.3% increase in net sales due largely to higher average selling prices, improved product mix, and a slight increase from the acquisition of Gienow into our Western Canada business.

• Gross margin improved by 270 basis points driven by a 470 basis point gross margin improvement in our U.S. business due to improved pricing and product mix partially offset by gross margin contraction in Western Canada due to near-term integration and restructuring costs related to the consolidation of manufacturing operations and unfavorable foreign currency exchange rates.

• SG&A expense increased by 6.2% which was attributed to the increase in net sales of the segment. SG&A expense as a percentage to net sales was 13.4% which is consistent with the prior year of 13.6%.

• 14.4% increase in net sales due to the acquisition of Mitten which was completed on May 31, 2013. Mitten favorably impacted net sales by $20.6 million for the quarter. Organic net sales increased 4.1% due to increased sales of metal accessories and higher selling prices.

• Gross margin declined by 50 basis points, driven by higher raw material costs and freight costs not yet offset by our recently announced selling price increases partially offset by cost savings/synergies experienced by Mitten.

• SG&A expense increased by $4.9 million of which $4.3 million is attributed to Mitten. Excluding Mitten, SG&A expense increased 3.6% which is consistent with the net sales increase.
