YTD sales of $250M is an all-time record sales level for a first-half.Single-family housing starts in Florida strengthened in Q2 2017, increasing 10% compared to Q2 2016. Single-family housing starts in Florida continue to track towards 85,000 for the year, but with the highest growth in new construction occurring in homes with lower opening price-points than seen last year.The growth in the housing market in Florida continues to out-pace the rest of the country, due to:Population expansion (projected to increase 325,000 in 2017; approaching 21M)Job creation (1.4M jobs added since a low of 8.1M in December 2009; now 9.7M employed)Declining unemployment (reached a high of 11.2% in December 2009; now 4.1%)We continue to develop innovative new products, and unveiled the next generation of our cutting-edge, new products at the 2017 NAHB International Builders Show.

 5  PGTI Second Quarter 2017 Financial ResultsJuly 1, 2017   Market Overview  Impact product sales increased 18% quarter-over-quarter, including quarter-over-quarter increases of 27% in vinyl impact products and 15% in aluminum impact products, both driven by sales of our WinGuard products.61% of our sales were from repair and remodeling, while sales in new construction represented 39%, a slightly higher mix of sales towards repair and remodeling. We believe lower new home inventories and increasing home prices, have led some would-be trade-up home buyers to remodel versus buy.As the third largest state in the U.S., the single largest factor for economic improvement in Florida continues to be the housing market.Florida single-family housing starts in Q2 2017 finished up 10% quarter-over-quarter.Florida single-family housing starts have increased in 23 of the last 26 consecutive quarters when compared the same quarter in the prior year.Florida single-family housing starts in 2016 finished at approximately 78,000.Florida’s population can support single-family housing starts of 110,000 per year.

 10  PGTI Second Quarter 2017 Financial ResultsJuly 1, 2017   2017 Outlook  We expect the voluntary prepayment of $12M we made on July 7th, will save approximately $3M in debt service costs over the remaining life of the 2016 Credit Agreement, including approximately $360,000 in the second half of 2017.Slight increases in LIBOR have resulted in our all-in borrowing rate under our term loan to increase to approximately 6%, from 5.75%. Total interest expense estimated to be approximately $19.1M in 2017.Depreciation and amortization will continue to increase due to significant capital investments made over the last three years, including manufacturing modernization, and expansion of capabilities and capacity, and acquisitions. We estimate that depreciation and amortization expense will be nearly $19M in 2017, an increase of more than $3M from 2016.Combined with a solid first half of 2017, we anticipate ending the year towards the high end of the ranges for consolidated sales and EBITDA we previously provided, which are sales of $490 to $500 million, and EBITDA of between $83 and $87 million.
