Thanks, Tim. Good afternoon, everyone. Thank you for joining us. ACV delivered solid top line results above our guidance range despite the persistent supply constraints weighing on the automotive industry and softening retail demand for used vehicles. We delivered EBITDA within our guidance range while continuing to invest in key growth expansion and technology initiatives. We continue to broaden and deepen our relationships with our dealer partners, who underpin our long-term growth opportunities. Automotive dealers faced the macro challenges I referenced earlier that they have proven to be resilient and are a critical part of the automotive ecosystem. Dealers have also embraced digital transformation, and ACV is increasingly well positioned to enable them to improve their ability to source, manage and sell vehicles with greater transparency and efficiency. With that, let me turn to the first quarter highlights on Slide 4. Our market momentum continued in the first quarter with revenue of $103 million; growth, 49% year-over-year. We transacted $2.4 billion of GMV, growth of 83% year-over-year. We sold 140,000 vehicles in our digital marketplace, a 9% increase year-over-year and an increase of 70% on a 2-year basis. Overall, we are very pleased with strong execution by the ACV team and continued customer adoption of our growing suite of services. Turning to Slide 5. To frame the rest of our discussion today, we will focus on the 3 pillars of our strategy to drive long-term shareholder value, growth, innovation and scale. I will begin with growth. Moving to Slide 7. Given the continued headwinds facing the automotive industry, we are providing context on the dealer wholesale market in relation to the broader automotive retail market. First, to understand the demand side of our market, we provided data on overall used car transactions and wholesale pricing trends. As you can see in the chart on the left, retail sales of used vehicles in Q1 experienced a seasonal sequential improvement over Q4 but was down about 10% year-over-year versus very strong performance in Q1 '21. Consumer demand for used vehicles is a key driver of wholesale demand and supply because consumers purchasing a used vehicle typically have a trade-in. The chart on the right illustrates how the modified consumer demand in Q1 impacted wholesale prices. After experiencing historically high wholesale prices throughout 2021, prices declined during the first quarter which does not mirror typical seasonal historical patterns. As I will describe in more detail later, this price deflation resulted in compression to conversion rates across the industry as dealers increasingly became more price-sensitive while buying vehicles in the wholesale market. Now turning to Slide 8. Let's look at the supply picture. New vehicle sales remained well below historical averages and we're down about 16% year-over-year in Q1 due to the ongoing supply challenges impacting vehicle production. This is reflected in the chart on the right, which shows the supply of light vehicles at franchise dealerships remain historically low. New vehicle supply is important to our business because consumer trade-ins for new purchases are a significant input into the wholesale market. With new vehicle inventories at these acute levels, the volume of trades entering the wholesale market has declined, resulting in a near-term contraction in the market we serve. While the exact timing for supply to return to historic metrics may be unclear, what is clear is that our ongoing investment in growth and differentiated products positions ACV to benefit from the resulting recovery in the wholesale market. So what gives us confidence in our strong market position. On Slide 9, we provided additional insights into our business. The chart on the left shows quarterly listings in our marketplace. Think of listings as a measure of dealer growth and marketplace adoption. As you can see, listings have grown consistently quarter-over-quarter with a notable exception of the beginning of the pandemic Q2 2020. Listing's growth moderated in the second half of '21 as supply pressures mounted in the industry. However, Q1 '22, listings recovered nicely, growing 37% year-over-year, reflecting strong execution on territory expansion, dealer penetration and wallet share growth, including higher-priced segment of vehicles. This is also a reflection of the changing sentiment as dealers are increasingly becoming more willing to wholesale vehicles. In the figure on the right, we've provided the quarterly variance in the marketplace conversion. There are 3 key takeaways: First, pre-COVID, you can see the conversion rates in our marketplace were quite consistent, varying just a few percentage points from the average; second, once COVID hit, conversion rates significantly increased, driven by the supply, demand, wholesale pricing factors I covered earlier; and third, as I mentioned, vehicle prices began to decline in Q1 '22, resulting in incrementally cautious buying behavior and further softening of conversion rates back to normal pre-COVID levels. For context, the year-over-year change in conversion rates in Q1 '22 was a 30,000 unit headwind versus Q1 '21. We believe conversion rates in our platform will increase in the future as we continue to invest in our data products to help dealers manage price expectations. Obviously, the historically high conversion rates, we and the industry experienced last year, benefited from the macro environment, but it's important context when assessing our year-over-year unit growth. Turning to Slide 10. You can see that units grew 9% year-over-year compared to 55% unit growth Q1 '22 and 70% unit growth on a 2-year basis. And despite softening wholesale prices, GMV grew 83% to $2.4 billion, resulting from a broader mix of vehicles in our marketplace. Moving on to Slide 11. Based on our internal analysis, we estimate that the U.S. wholesale TAM from retail dealers was flattish quarter-over-quarter but contracted around 18% year-over-year. So despite ongoing industry headwinds, we continue to access it, gain market share and attract new dealers to our marketplace. Given our 9% year-over-year unit growth in Q1 and an estimated market contraction of 18%, this would imply ACV grew market share by 27% year-over-year. Next, I would like to wrap up the growth section with highlights on our value-added services. We continue to invest in the technology and resources to scale ACV Transportation and ACV Capital. These investments are driving strong top line growth by delivering highly differentiated services to the market while also creating efficiency for both our partners and for ACV. On Slide 12, you can see that ACV Transportation continues to deliver strong results and remains a key enabler of attracting new buyers to the platform. Our growing carrier partner network and fast cycle times resulted in attach rates, once again, exceeding 50% in Q1, with the number of transports growing 45% year-over-year. In Q1, over 50% of our transports were automatically dispatched, which drove more efficiency in our transport operations. We also just recently launched the ACV Carrier Transportation app, which is a digital tool for carriers to efficiently manage their vehicle pickups and deliveries. Technologies like Auto Dispatch and the Carrier app help attract new carriers to our transfer marketplace and drive efficiencies, which is an important element of ACV's overall margin expansion strategy. Turning now to Slide 13. We are pleased with the execution in our ACV Capital business. Attach rates and capital have more than doubled year-over-year, resulting in 140% loan volume growth. The increased mix of higher-priced vehicles transacted in our marketplace, along with new ACV Capital offerings resulted in a 50% increase in revenue per loan in Q1. We are also investing in the technology powering our capital business to drive adoption and improve dealer engagement, which we believe will drive additional wallet share. The new ACV Capital Online Portal equips dealers with a seamless post-auction financing solution. This enhanced platform aligns with ACV's commitment by leveraging technology to deliver easy-to-use solution and transparency for dealer partners and will further enable ACV Capital being important growth and profit driver going forward. Turning to the second element of our strategy to drive long-term shareholder value, innovation. Now to Slide 15. I would like to highlight the innovations we're delivering to enable our dealer partners to drive consumer source inventory. Live Appraisal was our first offering in this category that contributed to our strong unit growth in '21 and continues to be a unique and effective way for consumers to sell their vehicles and ACV's marketplace through our dealer partners. Live Appraisal once again contributed a high single-digit percentage of our units in Q1 '22. The Live Appraisal is just the beginning. With the acquisitions of Drivably, Monk and MAX Digital, we are able to create a more comprehensive solution for our dealers on the consumer acquisition front, which we believe will increase our wallet share of dealer wholesale. Drivably provides a seamless consumer buying experience and is powered by the ACV pricing engine, which is our condition adjusted machine learning model for vehicle evaluation. This integrated appraisal tool provides an end-to-end experience for selling a consumer's car. Our ability to deliver trusted vehicle valuation because of our expensive proprietary data enables dealers to provide attractive offers to their consumers, which means sourcing for more customers for the dealership, which in turn drives more wholesale supply. We also plan to leverage Monk's AI-driven imaging technology to enable consumers to do a self-inspection right from their own mobile device, which will further inform that price dealers can offer consumers. We are in the early stages of launching dealers on this new platform, and we are very excited about consumer sourcing, an attractive TAM expansion and wallet share opportunity for ACV. Moving to Slide 16. We are very pleased with the market traction we're seeing with our MAX Digital SaaS and data-enabled offerings and the synergies created by the ACV MAX combination. Why this combination is so powerful? MAX has a significant volume of data and suite of services from its long history in retail automotive. ACV has amassed a huge volume of data in wholesale automotive. Merging all that data and intelligence together creates insights for our dealers. It will help power both MAX and all ACV products. Leveraging our growing moat of dealer retail and wholesale data, we can make recommendations that are localized and personalized for a particular dealer. The ability to drive dealer-specific insights is key as it drives better outcomes for both the retail and wholesale side of the business. Moving to Slide 17. I am pleased to share an update to our advanced fire tools, including the previously shared programmatic buying goes. We are about to increase our go-to-market presence, including the introduction of a brand initiative. These tools will now be offered under the brand, SAM, an acronym for Smart Acquisition Manager. Thanks to SAM, buying an ACV has never been easier. By creating specific and relevant notifications as well as powering intelligent auto bidding, SAM brings broad and persistent demand for the platform, complementing our marketplace in driving price realization and conversion for our sellers. And SAM also informs our algorithms and pricing engine to help dealers understand vehicle pricing. SAM is already contributing over 5% of our quarterly unit volume, and we believe it will be a big growth driver for us as we expand its use cases and capabilities. Simply put, every dealer needs SAM. So to wrap up on innovation, we are very excited about our growing suite of data-enabled solutions and technology road map that expands our competitive moat, creates even more value for our dealer partners and drive sustainable long-term growth. With that, let me hand it over to Bill to take you through our financial results and how we're driving growth at scale.
