Thank you. Good afternoon. Thank you for joining us for the Aspen Aerogels Conference Call. I'm John Fairbanks, Aspen's Chief Financial Officer. There are a few housekeeping items that I would like to address before turning the call over to Don Young, Aspen's President and CEO. The press release announcing Aspen's financial results and business developments, as well as the reconciliation of management's use of non-GAAP financial measures compared to the most applicable GAAP measures, is available on the investor section of Aspen's website, www.arajel.com. Included in the press release is a summary statement of operations, a summary balance sheet, and a summary of key financial and operating statistics for the fourth quarter and year ended December 31st, 2020. In addition, the investor section of Aspen's website will contain an archived version of this webcast for approximately one year. Please note that our discussion today will include forward-looking statements, including any statement regarding outlook, expectations, beliefs, projections, estimates, targets, prospects, business plans, and any other statement that is not a historical fact. These forward-looking statements are subject to risks and uncertainties. Aspen Aerogel's actual results may differ materially from those expressed in these forward-looking statements. A list of factors that could affect the company's actual results can be found in Aspen's press release issued today and discussed in more detail on the reports Aspen files with the SEC, particularly in the company's most recent annual report on Form 10-K. The company's press release issued today and filings with the SEC can also be found in the Investors section of Aspen's website. These forward-looking statements made today represent the company's views as of today, February 18th, 2021. Aspen disclaims any obligation to update these forward-looking statements to reflect future events or circumstances. During this call, we will refer to non-GAAP financial measures, including adjusted EBITDA. These financial measures are not prepared in accordance with U.S. generally accepted accounting principles or GAAP. These non-GAAP financial measures are not intended to be considered in isolation or as a substitute for results prepared in accordance with GAAP. The definitions and reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures and a discussion of why we present these non-GAAP financial measures are included in today's press release. I would also like to note that over the next two weeks, in connection with the vesting of restricted stock units issued under our long-term equity incentive program, our Section 16 officers will file Form 4s to report the withholding of shares by the company to satisfy statutory tax obligation related to the vestings of these RSUs. I want to emphasize that the shares that were held by Aspen will not be sold into the market and will remain unissued. I'll now turn the call over to Don.

Thank you, John. Good afternoon. Thank you for joining us for our Q4 2020 earnings call. Today, John and I are switching up the usual order of our comments. John will start with a recap of our 2020 full year performance and finish with our outlook for 2021. I will follow John by providing a strategic overview of the company and by outlining the significant opportunities we have before us. This evening, we also uploaded a new company presentation to the investor section of our website that expands upon my comments. We will conclude today's call with a Q&A session. John, over to you.
