Thank you, operator, and good afternoon, everyone. Welcome to Magnite's first quarter 2022 Earnings Conference Call. As a reminder, the comparisons you will see in the 10-Q as reported include the financial results of SpotX and SpringServe for Q1 2022, but for the periods prior to the acquisition dates, the results do not include SpotX or SpringServe, which were acquired on April 30, 2021, and July 1, 2021, respectively. During the course of this call, when we refer to the results and associated year-over-year comparisons with the phrase as reported, we are referring to the basis as reported in our 10-Q. When we make comments referring to pro forma comparisons, we are including SpotX and SpringServe for the relevant pre-acquisition period in order to provide a like-for-like comparison. Please keep in mind as it relates to the SpotX and SpringServe acquisitions, prior quarterly results are estimated and unaudited. As a reminder, this conference call is being recorded. Joining me on the call today are Michael Barrett, CEO; and David Day, our CFO. I would like to point out that we have posted financial highlight slides on our Investor Relations website to accompany today's presentation. Before we get started, I will remind you that our prepared remarks and answers to questions will include information that might be considered to be forward-looking statements, including, but not limited to, statements concerning our anticipated financial performance and strategic objectives, including the potential impact of macroeconomic factors on our business. These statements are not guarantees of future performance. They reflect our current views with respect to future events and are based on assumptions and estimates, and subject to known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from expectations or results projected or implied by forward-looking statements. A discussion of these and other risks, uncertainties and assumptions is set forth in the company's periodic reports filed with the SEC, including our first quarter 2022 quarterly report on Form 10-Q and our 10-K. We undertake no obligation to update forward-looking statements or relevant risks. Our commentary today will include non-GAAP financial measures, including revenue ex-TAC or less traffic acquisition costs, adjusted EBITDA and non-GAAP income per share. Reconciliations between GAAP and non-GAAP metrics for our reported results can be found in our earnings press release and in the financial highlights deck that is posted on our Investor Relations website. At times, in response to your questions, we may offer incremental metrics to provide greater insights into the dynamics of our business. Please be advised that this additional detail may be one-time in nature, and we may or may not provide an update on the future of these metrics. I encourage you to visit our Investor Relations website to access our press release, financial highlights deck, periodic SEC reports and webcast replay of today's call to learn more about Magnite. I will now turn the call over to Michael. Michael, please go ahead.
