Thank you, Cathy. And good evening, and welcome to our first quarter fiscal 2021 earnings call. On the call with me, as Kathy said, is Frank Lonegro, our Chief Financial Officer. Our prepared remarks will correspond with the slide deck, which is posted to the Investor Relations section of Beacon's website. Before I get into the details, as you know, we have announced the divestiture of our Interiors business. As such, we are providing two sets of financial information in today's earnings release. The primary focus will be on our continuing operations, which focuses solely on the exteriors business and treats interiors as discontinued operations. I know many of your models are still based on the combined company, so we've also provided summary information on the combined results. I hope the additional information will help you better gauge our first quarter performance and support your analysis going forward. On a continuing basis, we generated Q1 sales of $1.6 billion, an 11.4% year-on-year increase. Adjusted EBITDA improved to $143 million from $77 million the prior year. On a combined basis, so including interiors, sales were $1.8 billion, with 9% sales growth. Adjusted EBITDA for the combined business was $158 million compared to $94 million in fiscal Q1 last year. We believe both sets of numbers are important in understanding our first quarter results, but our remaining commentary in this evening will focus on the continuing exteriors business. Within the appendix of our slide presentation, we've included supplemental 2019 and 2020 income statements for the continuing exteriors business that should help you in modeling our pro forma financials. I'll now begin on page four of the slide materials, which focuses on our first quarter continuing results. Our fiscal 2021 is off to a great start. First quarter continuing adjusted EBITDA increased 86%, driven by the strongest quarterly organic sales growth in more than 4 years and one of the best first quarter EBITDA margin percentages in over a decade. We have strong leadership, and I'm very proud of the team's execution the past three or four quarters. I believe that this quarter gives you a sense of what the company is capable of delivering. Now there are several important takeaways from the first quarter. First, the residential demand is strong. Residential roofing sales increased 21% in the quarter. Strong reroofing and new construction activity was paced by milder weather, which opened up additional workdays for our customers. In a few Gulf States, demand was boosted by hurricane-related repair work, and the strong demand environment provides a favorable backdrop for the successful price increase we implemented in August. The positive housing market fundamentals also helped boost exterior complementary products. With the divestiture of interiors, our product mix is now more residentially focused and biased towards repair and replacement activity. Second, we continue to demonstrate good execution on our price actions. As highlighted during our last quarterly call, our team moved quickly in response to the August shingle price announcement from the manufacturers. We implemented higher prices to essentially coincide with the timing of the supplier increases. And as we have discussed previously, the timing and execution of our price initiatives creates favorable timing benefits, which positively contributed to gross margins in Q4 '20 and continued in the first quarter of fiscal '21. First quarter gross margins were 25.4% for continuing operations, exceeding our expectations. We continue to see inflationary pressures across most product categories, and we are confident in the current environment, we can capture additional pricing opportunities to more than offset the cost headwinds. Third, first quarter results demonstrate our ability to manage operating costs. One of our central goals as a leadership team is to aggressively manage costs in all demand environments. We are extremely proud of our expense management during the past three COVID impacted quarters, but we recognize that with all of them is passed during COVID and the year end close, determining the impact of our actions has been difficult. We see the first quarter as an indication of the progress we've made. During Q1, continuing adjusted OpEx dollars declined 3% year-on-year despite an 11% sales increase and a higher than normal residential mix, which is typically higher cost to serve. In a growth environment, an important part of our focus is to generate significant operating leverage, closely watching costs and managing the controllable aspects our day-to-day considerations as we run the business. Now please turn to page five of our slide materials. In our previous outlook commentary, we’ve taken a more cautious view on quarterly results, reflecting the potential impact of weather disruptions. However, our November and December monthly sales growth accelerated meaningfully, a reflection of strong underlying demand and favorable weather conditions. Our continuing business finished a strong 11.4% sales growth for the quarter. Gross margins at 25.4% was stronger than anticipated, with the upside from favorable residential mix, supplier incentives tied to higher volumes and continued price execution. Our first quarter operating expense outlook, centered on cost management tied to anticipated winterization during the quarter. As noted earlier, we're very pleased to report the meaningful OpEx decline, even with robust sales growth. Frank will share some of our specific productivity measures later. For the continuing business, adjusted EBITDA increased from $77 million to $143 million, and EBITDA margins increased from 5.4% to 9.1%. The favorable performance was driven by a combination of strong sales growth, a significant year-to-year increase in gross margin and a reduction in operating costs, resulting in significant OpEx leverage. Moving to page six of our slide materials. Let me provide you an update of our planned interior divestiture and a view of our business following the transactions closed. We announced in late December, the sale of our interiors business to American Securities who will subsequently integrate the transaction with their recently completed acquisition of Foundation Building Materials. We are making great progress and expect the deal will close later this week. The interiors business includes more than 80 branches focused on wallboard, ceiling tile and grid, steel starts and insulation products. Interiors operates from a separate branch network from our exteriors locations, making for a clean separation of the business. We were pleased with the outcome of the process and secured an attractive valuation of $850 million for the interiors business. Importantly, the proceeds allow us to improve our balance sheet, immediately lower our net debt leverage to very near our previously published targets and provides us with much greater financial flexibility. The divestment will return Beacon to its legacy position as a focused leader with an exterior building products distribution. 80% to 85% of our continuing business will be within residential and commercial roofing. We reviewed the roofing market attributes as relatively unique. More than 80% of residential and non-residential roofing is classified as repair and replacement, with the majority of that being non-discretionary and driven by the replacement of worn or damaged roofs. The remaining 15% to 20% of our exteriors business is complementary products, consisting largely of siding, windows and doors, lumber and wood roofing products. These exterior complementary products have some overlap with roofing customers and shared distribution facilities providing meaningful sales and operating synergies. To summarize, we feel the interiors divestiture represents a transformative strategic event for the company, narrowing management's focus, substantially improving our balance sheet and financial flexibility and concentrating the business around our core capabilities. Next, please turn to page seven of the slide deck. In recent quarters, we provided updates of each of these four strategic initiatives. In light of the interiors divestiture, we felt it was appropriate to reset our financial targets and metrics for each. These initiatives remain central to our improved sales growth, operational efficiency and profitability. Some of the impact can be directly measured. There are also additional benefits for which are less obvious, but play an important role differentiating us from competitors and adding incremental value from customers. Let me begin with organic growth. This initiative is focused on improving both the number and the effectiveness of interactions between our sales organization and customers. We continue to invest in sales training programs, marketing support, and value added tools that help our sales people track their contacts with existing and potential new customers. And we have established targets for our sales team involved in the number of interactions daily, and we know that meeting these objectives strongly correlates to driving overall company sales performance. Next is our industry-leading digital platform. Digital is a clear differentiator in the marketplace for Beacon. During our last quarterly call, we disclosed that digital sales had reached a run rate of 10% of total company sales during the final month of fiscal 2020. Our exteriors business was further along the adoption curve than interiors, so we expect to see another bump in adoption this year. We have continued to leverage the customer adoption rates that accelerated during the early COVID environment, and are confident our current year and long-term growth trajectory will cement our leadership. Digital is an excellent example of how a sharpened post divestiture focus should pay dividends for growth. Our marketing organization will now be able to devote 100% of their time to the exteriors products on the platform and develop new offerings. Next, moving to our On Time & Complete Network, our OTC strategy creates a network of branches in larger MSAs. We operate in 58 distinct markets and have more than 250 exteriors branches participating in OTC. OTC provides four key benefits. First is improved customer service as we have created the flexibility to deliver from the branch with the best combination of product and service to support the customer’s needs. Second is a lower cost to serve. Since we can optimize across a network of branches, we get reduced delivery time and mileage, improving labor efficiency and reducing fleet costs and emissions. Third, reduced inventory levels. We previously indicated we believe we can permanently reduce our inventory by $50 million to $100 million as we optimize across our OTC branches, and we remain confident that we can hit that target. And fourth, we can accelerate our talent development. Our OTC creates opportunities for our people to explore a variety of roles at Beacon and build increasing levels of responsibility, allowing them to build great careers at our company and reach their full potential. Lastly, I want to update our branch operating performance targets. I talked extensively about our focus on the volume quintile [ph] branches and our goal to significantly improve the operating performance. We've developed a diagnostic tool and a reporting cadence that places emphasis on structural change to secure we get sustained improvement. We previously guided to a $30 million to $60 million improvement at these branches that will be achieved over several years. We shared on our prior earnings call and in fiscal 2020 we've seen a more than $20 million year-over-year improvement, the majority of which came from exteriors branches. With the success we saw during the first year of the program, we are now resetting our 2021 target to a $20 million year-on-year improvement from the lowest quintile exteriors branches. Each year, we will continue to focus on driving sales and operating improvements to bring these branches over time up to at least to our company average. To summarize, my update on our strategic initiatives, even the objectives, nor the anticipated impacts to Beacon, have changed following the interiors divestiture. Instead, it has sharpened our focus on these programs might be enhancing their effectiveness over time. Now, I will pass the call over to Frank to provide deeper focus on our first quarter continuing results.
