 4  PGTI Third Quarter 2017 Financial ResultsSeptember 30, 2017   Impacts of Hurricane Irma (1 of 2)  Sales impact to Q3 2017 estimated at $13M; added costs to Q3 2017 estimated at $1.1M.Hurricane Irma, the first major hurricane to hit our market since 2005, made landfall in Florida on September 10th.Irma was a Category 4 storm upon landfall in the Florida Keys, with sustained 130-mph winds, and at one point before landfall, set record by maintaining 185-mph winds for 37 straight hours.Largest and most powerful storm ever recorded in the Atlantic.400-mile-wide storm covered the entire state as it moved north along Florida’s Gulf Coast.Significant wind-borne damage in western FL; Severe storm-surge flooding in eastern FL.Our entire market of Florida impacted to some degree (FL represents 90% of our sales). Our South FL market was especially hard hit (South FL represents 70% of our sales).Estimated between 5M and 6M people (or between 25% and 30% of the state) evacuated. Damages from Irma estimated to be between $50B and $100B in Southeast U.S.Including Irma, damages from 2017 Hurricane Season estimated to be between $150B and $400B. 

 5  PGTI Third Quarter 2017 Financial ResultsSeptember 30, 2017   Impacts of Hurricane Irma (2 of 2)  Through July/August 2017, versus same two-months last year, sales were up 5%.These solid sales produced strong operating results, as adjusted EBITDA margin for July/August 2017 was 19.3%, compared to 17.9% during same two-months last year.Early September 2017 operations were similarly strong.As Irma approached Florida, order levels dropped by as much as 50% due to customer shut-downs.Certain of our production facilities ceased operating for up to 6 days, with no shipping or production.We believe we would have set another record for quarterly sales in Q3 2017 absent the storm.Added costs in Q3 2017 include increased distribution and warehousing costs, incremental costs to bring facilities back up to full production, and our Community Outreach efforts, to help those affected by the storm in the local area and certain other markets we serve in FL, providing members of the community with things like free generators, chainsaws, food, water and other supplies.We still felt the effects of Irma in the first half of October 2017, but stronger sales in the second half of October 2017 helped deliver total sales for the month of approximately $41.5M, up 12%, and EBITDA margin of about 18.0%, versus 15.3%, both as compared to October 2016.

 12  PGTI Third Quarter 2017 Financial ResultsSeptember 30, 2017   2017 Outlook  We estimate that Q3 2017 sales were negatively impacted by approximately $13M due to Hurricane Irma, some of which is expected to be recovered in Q4 2017, with the remainder expected to fall into 2018.For the full year of 2017, we expect to finish within the previous guidance range for consolidated sales of $490M to $500M, and we are revising our estimate of adjusted EBITDA to be between $80M and $84M, due to additional SG&A investments, including television advertising spending, associated with awareness for impact-resistant products, as well as the effect on EBITDA from lower sales as the result of Irma.
