Brendan Moynihan --
Vice President, Financial Planning and Investor Relations
Thank you. Good morning, everyone, and welcome to Lydall's First Quarter 2021 Earnings Conference Call. Joining me on today's call are Sara Greenstein, President and Chief Executive Officer; and Randy Gonzales, Executive Vice President and Chief Financial Officer. Sara will begin the call with a high-level overview of the quarter, including the actions taken to solidify Lydall's position as a world leader in specialty filtration and advanced materials solutions. Randy will follow with a review of our financial performance and discuss the key business drivers by segment. Sara will then conclude the call with a brief discussion on our current outlook, immediate priorities, and how we are well positioned for long-term growth. At the end of their remarks, we'll open the line for questions. Our quarterly earnings release was issued along with the filing of our quarterly Form 10-Q. Both are available on our Investor Relations website, ir.lydall.com and can be used as referenced for today's call, along with the Q1 2021 earnings conference call presentation, which can be found at lydall.com in the Investor Relations section. As noted on slide two of this presentation, any comments made on this conference call that may constitute forward-looking statements are made available pursuant to the safe harbor provision as defined in the securities laws. Please also refer to the cautionary note concerning forward-looking statements within Lydall's Form 10-Q for further information. In addition, we will be referring to non-GAAP financial measures during this conference call. A reconciliation to GAAP financials can be found in the appendix of the presentation I just referenced.
