Key Highlights

Third Quarter 2015 Highlights

• Sales increase of 21.2% was primarily due to the Simonton and Canyon Stone acquisitions and growth within the U.S. businesses in each segment. The growth in the U.S. was partially offset by weaker market conditions in Canada and unfavorable foreign currency exchange rates which negatively impacted sales by $11.4.

• Gross margin expansion of 290 basis points primarily driven by increased average selling prices in both of our business segments, favorable freight costs, and favorable commodity costs, partially offset by unfavorable foreign currency impact from a weakening Canadian dollar.

• Sixth consecutive year-over-year quarterly adjusted EBITDA improvement. Excluding acquisitions, incremental year-over-year quarterly adjusted EBITDA growth of 18.5%.

End Market Exposure (*)

• 42.6% increase in sales due largely to the Simonton acquisition which accounted for $81.9 of the sales growth. Excluding Simonton, sales for the U.S. business increased 12.6% due to higher average selling prices, improved product mix, and improvement in U.S. market conditions. Growth in the U.S. was partially offset by weaker market conditions in Western Canada and unfavorable foreign currency exchange rates which negatively impacted sales by $5.9.

• Gross margin improved by 530 basis points driven by $23.7 of Simonton gross margin and a 200 basis point gross margin improvement in our legacy windows businesses due to improved pricing, and product mix partially offset by unfavorable foreign currency.

• SG&A expense increase includes $16.2 of expense attributable to Simonton. Excluding Simonton, SG&A expense as a percent of net sales decreased from 12.3% to 9.7%. Reduction of legal expenses accounted for 170 basis points of the decrease. The remainder relates to reductions in one-time restructuring and integration costs in Western Canada, and expense reduction initiatives in response to lower market demand in Western Canada.

• 4.4% increase in sales due largely to the Canyon Stone acquisition which accounted for $7.8 of the sales growth. Excluding Canyon Stone, sales for the U.S. business increased 4.2% due to favorable market demand and higher selling prices for our products. Growth in the U.S. was partially offset by unfavorable foreign currency exchange rates which negatively impacted sales by $5.5.

• Gross margin expanded by 220 basis points, driven by improved operating leverage from the sales increase, improved selling prices, favorable material cost pricing, and favorable freight expense, partially offset by unfavorable foreign currency.

• SG&A expense increased $2.4 which was due largely to the Canyon Stone acquisition which accounted for $1.3 of the SG&A expense increase. Excluding Canyon Stone, SG&A expense as a percent of sales increased from 8.4% to 8.7% which was mainly due to increased incentive compensation.

Continued Implementation of Enterprise Lean and Sales & Operations Planning (S&OP) System in U.S. Windows and Doors

New Channels and Markets 4Q 2015 Guidance

Based on the forecasted growth of the U.S. housing market and R&R spend, the impact of our enacted selling price increases and other margin enhancing initiatives, the expected impact of Canyon Stone, anticipated acquisition synergies, commodity fluctuations and a normalized weather pattern, we expect our adjusted EBITDA for 4Q 2015, in the range of $32.0 to $37.0

Economic Outlook & Guidance

Expect Continued Steady Growth in U.S. Housing Starts

Expect continued overall moderate growth of high single digits in U.S. housing recovery in 2015, however we expect the market to experience periods of choppiness in the growth rate

Expect an overall moderate growth rate for big ticket R&R spend of approximately 2% to 3% in 2015

Overall Canadian housing starts expected to moderate relative to 2014 with lower starts in oil-producing regions of Western Canada partially offset by higher starts in other regions
