Thanks, Julie. Good morning, everyone, and thank you for joining us on the call today. We have more information than usual to cover. but considering the events in Ukraine and Europe, we will try to be as efficient as possible, and our thoughts are with those who are affected. We are pleased to report a strong finish to 2021. Our teams delivered excellent execution across our segments, and we are grateful for their hard work. For the fourth quarter, we earned $1.04 per share on revenue of $856 million. Same store revenue grew by 8% compared to the fourth quarter of 2020, as overall non-residential building construction and service continue to show broad-based strength. For the first time ever, we are reporting more than $3 billion in four-year revenues. We have good cash flow, and our backlog has registered an unprecedented increase. In addition, in January of 2022, we received approvals of previously filed tax refund claims for the past years that will meaningfully impact our first quarter results, and Bill will review those in detail during his remarks. We had an active fourth quarter for acquisitions. At the beginning of December, we acquired Ivey Mechanical, which services customers across the southeastern United States. We have known Ivey for 25 years, and their mechanical construction and service expertise is well positioned for collaboration and mutual benefits. On the last day of December, we acquired Edwards Electrical and Mechanical based in Indiana. Edwards brings us a solid, full-service presence in Indianapolis and provides new capabilities in clean room solutions that will complement our off-site construction and prefabrication. On December 31st, we also acquired a strong service and controls business in Kentucky, Thermal Solutions. And on that same day, we acquired Kodiak Labor Solutions, a temporary staffing agency that we have worked with on an ongoing basis and which will help us recruit and deploy skilled construction labor in many of our markets. We are happy to have these strong teams as a great new part of Comfort Systems USA, and we are confident that we have added some wonderful people and strong capabilities. I will discuss our business and outlook in a few minutes, But first, I will turn this call over to Bill to review our financial performance. Bill?
