Key Highlights
• Sales increased $34.2M during the quarter. Our U.S.
businesses experienced an organic growth rate of 6.4%
which was primarily driven by increased demand for our
products within our Siding, Fencing and Stone segment
and our new construction windows and doors. Favorable
price and product mix provided a sales increase of
$13.6M within our segments. Including the impact of
$1.9M in unfavorable currency exchange rates and
favorable pricing product mix, Canadian sales increased
$4.6M during the quarter.
• Gross margin contracted 140 basis points primarily driven
by unfavorable commodity costs, mainly PVC resin and
aluminum, relative to Q2 2016 in our Siding, Fencing &
Stone segment, partially offset by higher average selling
prices in our Siding, Fencing & Stone and Windows and
Doors segments.
• Adjusted EBITDA margin decreased slightly by 20 basis
points due to unfavorable commodity and material costs
partially offset by higher average selling prices in both of
our business segments.
• Thirteenth consecutive year-over-year quarterly adjusted
EBITDA improvement. Incremental year-over-year
quarterly adjusted EBITDA growth of 5.4%.
• Q2 2017 LTM adjusted EBITDA of $235.6M.

Key Highlights
• Sales increase of $55.6M during the first half of 2017 was
primarily due to organic growth in our U.S. and Canadian
businesses. Our U.S. and Canadian businesses
experienced organic growth rates of 6.7% and 8.6%,
respectively, which was primarily driven by increased
demand for our products within our Siding, Fencing and
Stone segment and our new construction windows and
doors. Favorable price and product mix provided a sales
increase of $24.6M within our segments. Including the
impact of favorable currency exchange rates and
favorable price and product mix, Canadian sales during
the first half increased $6.6M. These sales drivers were
partially offset by $6.2M resulting from 1 less shipping day
in the first quarter compared to 2016 due to the
Company’s fiscal calendar.
• Gross margin contracted 100 basis points primarily driven
by unfavorable commodity costs, mainly PVC resin and
aluminum, in our Siding, Fencing & Stone segment,
partially offset by higher average selling prices in our
Siding, Fencing & Stone and Windows and Doors
segments.
• Adjusted EBITDA increased $6.5M or 6.4% due to higher
sales levels within both of our segments. Adjusted
EBITDA margin was consistent with the prior period.

Key Highlights
• Sales were favorable by $15.0M or 5.7% primarily driven by organic
growth of our U.S. new construction products and Canadian business
and favorable price and product mix. Our U.S. new construction
business increased $12.3M or 7.4%, which was partially offset by a
$1.0M decrease in our U.S. repair & remodeling products. Our
Canadian business increased $3.7M or 16.6% which was partially offset
by an unfavorable foreign currency exchange of $1.0M.
• Gross margin expanded by 110 basis points primarily driven by
improved pricing and product mix for our U.S. new construction
products and Canadian business, partially offset by increased
commodity costs, mainly PVC resin, aluminum and glass, increased
freight costs and a slight deterioration of gross margins in our U.S.
repair and remodel products.
• SG&A expense decreased $0.4M during the quarter. As a percent of
sales, SG&A expense decreased 90 basis points from 13.7% to 12.8% as
a result of improved leverage on the fixed component of SG&A
expense.
