Key HighlightsThird Quarter Results

Third Quarter 2014 Highlights

• Net sales increase of 7.5% was due to a 7.2% increase in U.S. single-family housing starts, an increase in average selling prices in both of our business segments and the acquisition of Simonton.

• Gross margin expansion of 180 basis points driven by increased average selling prices and operating efficiency improvements in our U.S. windows business partially offset by integration and restructuring costs related to the consolidation of our Western Canadian windows business and unfavorable foreign currency impact from a weakening Canadian dollar.

End Market Exposure

• 7.9% increase in net sales due to the Simonton acquisition. Excluding Simonton, net sales increased 3.9% due to higher average selling prices, improved product mix, increased New-co window units partially offset by unfavorable window unit sales to dealer customers and the weakening Canadian dollar in our Western Canada business.

• Gross margin improved by 380 basis points driven by a 710 basis point gross margin improvement in our legacy U.S. business due to improved pricing, product mix and manufacturing efficiencies 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 3.9% which was attributed to the Simonton acquisition and one-time integration costs of our Western Canadian businesses. Excluding Simonton and Western Canada integration costs, SG&A expense decreased 5.3%.

End Market Exposure (*)

• 7.1% increase in net sales due largely to favorable market demand in metal accessories and vinyl siding with units shipped increasing 15.6% and 6.8%, respectively. In addition, higher selling prices were realized in response to increased raw material costs.

• Gross margin expanded by 40 basis points, driven by increased selling prices, improved operating leverage resulting from favorable demand and volume, and cost savings/synergies experienced by Mitten offsetting higher materials costs.

• SG&A expense experienced a minor increase of $0.3 million. SG&A expense as a percentage of sales decreased from 8.9% in the prior year to 8.4% which is attributed to leveraging the fixed component of SG&A expense.

Mitten gross margin improvements associated with cost savings and synergies related to raw material sourcing, material improvements, and manufacturing efficiencies.

Increased raw material costs, mainly PVC and aluminum commodity costs partially offset by remaining impact of the Q1 2014 price increases. Additional recovery through future selling price increases.

Improved operating leverage as volume and demand increased, and favorable warranty claim rates.
