Thanks, Tim. Good afternoon, everyone, and thank you for joining us. We are very pleased with our second quarter performance, with revenue and EBITDA, both exceeding guidance. The ACV team once again delivered strong results in a challenging macro environment for our dealer partners. With that, let me turn to second quarter highlights on slide four. Our market momentum continued in the second quarter, with record revenue of $115 million, year-over-year growth of 18% versus very strong results in Q2 2021. GMV of $2.7 billion also set a new record and increased 27% year-over-year. We sold 148,000 vehicles on our digital marketplace, a 6% sequential increase from Q1 and a modest decline versus record unit performance in Q2 2021. Overall, we are very pleased with our execution in Q2 and our progress on key strategic initiatives. We delivered strong results despite wholesale market conditions that softened in June, resulting from continued supply challenges, weakening retail demand and vehicle price depreciation. Market conditions have remained challenging in Q3. And in prudent, we have assumed that wholesale volumes will remain constrained in the back half of 2022. Our guidance now reflects this more cautious view of the macro factors impacting the dealer wholesale market. Our guidance also reflects our commitment to investing in growth, while ensuring we remain squarely focused on our path to profitability. As Bill will detail later, we have adjusted our operating expense plans to account for expected market headwinds. We are focused on improving our foundation to drive profitable growth, when market headwinds turn into tailwinds for ACV. Turning to slide five. To frame the rest of our discussion today, we will focus on the three pillars of our strategy to drive long-term shareholder value; growth, innovation and scale. I will begin with growth. Moving to slide seven. I'll again provide context on the dealer wholesale market in relation to the broader automotive retail market. First, to illustrate the demand side of our market, we've 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 declined sequentially from Q1 and declined about 15% year-over-year versus strong performance in Q2 2021. As a reminder, consumer demand for used vehicles is a key driver of wholesale demand and supply, because consumers purchasing a vehicle typically have a trade-in. Chart on the right illustrates how continued softening of consumer demand has impacted wholesale prices. After reaching historically high levels in 2021, wholesale prices declined during the first quarter, recovered in early Q2, but have been trending down since June. As we discussed last quarter, price deflation has contributed to conversion rate compression across the industry, as dealers have become more price sensitive when 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 were down about 21% year-over-year in Q2, due to the ongoing supply challenges impacting vehicle production. This is reflected in the chart on the right, which shows that supply of new vehicles remains historically low, because consumer trade-ins for new purchases are a significant input into the wholesale market, the supply chain issues continue to weigh on the market we serve. While there have been a few positive signals from auto OEMs regarding production improvements later this year, we have not assumed this in our 2022 outlook. On Slide 9, we provided additional insight into our business that underpins our confidence in ACV's market position and long-term growth opportunities. The chart on the left shows quarterly listings in our marketplace, which is a measure of dealer growth and marketplace adoption. After moderating the second half of 2021 as supply issues mounted, listing volume turned positive in Q1, and then increased again in Q2. For the first half of 2022, listings grew 27% year-over-year, reflecting strong execution on dealer penetration and wallet share growth. In fact, the number of listings dealers increased 30% year-over-year in Q2, which positions ACV for strong growth once wholesale volumes recover. In the figure on the right we provided an updated view of the quarterly variance in marketplace conversion. As we discussed last quarter, pre-COVID conversion rates in our marketplace were in a pretty tight range. Then increased significantly as pandemic-related supply demand and wholesale pricing factors drove very strong marketplace engagement. Then beginning in the first quarter this year, as vehicle prices and consumer demand moderated cautious buying behavior resulted in conversion rates returning to normal pre-COVID levels. This trend continued in Q2 with conversion rates ticking down quarter-over-quarter. For context, the year-over-year change in conversion rate in Q2 resulted in a 30,000 unit headwind versus Q2 2021. We believe conversion rates in our platform will increase in the future when the macro environment normalizes and as we help dealers manage price expectations with new data-enabled solutions. However, based on the latest data showing weakening consumer sentiment, and depreciating wholesale market prices, we believe it's prudent to assume conversion rates will remain at the lower end of the historical ranges for the balance of 2022. Turning to Slide 10. You can see that units grew sequentially from Q1 and declined modestly year-over-year, compared to record high unit performance in Q2 2021. Unit growth was 68%, on a two year basis. GMV grew 27% year-over-year to a record $2.7 billion. About half of the year-over-year growth, was driven by higher wholesale prices with the other half reflecting, a broader mix of vehicles on our marketplace. Moving to Slide 11. Based on our internal analysis, we estimate that the US dealer wholesale market remains well below normalized volumes, and contracted around 20% year-over-year in Q2. Despite this macro backdrop, we continue to execute, gain market share and attract new dealers to our marketplace. Given our 3% year-over-year unit decline in Q2 and an estimated market contraction of 20%, this implies that ACV grew market share by 17% year-over-year. Next I would like to wrap up the growth section, with highlights on our value-added services. Our investments in the technology and resources, to scale ACV Transportation and ACV Capital, are driving strong top-line growth while also creating efficiencies for both our partners and for ACV. On Slide 12, you can see that ACV Transportation continues to deliver strong results. Our growing carrier partner network and fast cycle times, resulted in attach rates once again exceeding 50% in Q2, with transport revenue growing 20% year-over-year. In Q2, over 70% of our transports were automatically dispatched, an increase of 20 percentage points from Q1. The investment we are making in technologies like Auto Dispatch and our Carrier Transportation app, are attracting new carriers to our marketplace and driving operating efficiencies. In fact, our transfer business had a key milestone in Q2, with positive revenue margins in the mid-single-digits. As a reminder, our 2026 financial targets assume transport revenue margin of 15%. So hitting the mid-single-digits in Q2 2022 puts us on a strong path to achieving this target. Turning now to Slide 13. We are very pleased with the execution in our ACV Capital business. Capital attach rates more than doubled year-over-year in Q2, resulting in over 100% loan volume growth. Our investment in technology to power our Capital business is paying dividends. ACV's Capital Portal launched in Q1, and adoption has been strong with 75% of active ACV Capital dealers, now leveraging this value-added, post-auction financing solution. We also ramped up our investment in ACV Capital sales capacity, to drive adoption and dealer engagemen,t which will further enable ACV Capital to be an important growth and profit driver going forward. Turning to the second element of our strategy, to drive long-term shareholder value innovation. Turning now to Slide 15. I would like to highlight the innovations we're delivering to enable our dealer partners, to drive consumer-sourced inventory. Live Appraisal was one of our first offerings in this category, and provides a unique way for consumers to have their vehicles sold in ACV's marketplace, by our dealer partners. Live Appraisal was one of our first offerings in this category, and provides a unique way for consumers to have their vehicles sold in ACV's marketplace by our dealer partners. Live Appraisal listings grew 30% year-over-year in Q2 highlighting the market traction this offering is gaining. In addition to Live Appraisal we are developing a more comprehensive set of solutions for our dealers leveraging technology from Drivably, Monk and MAX Digital. The initial market reception for Drivably has been very promising with the number of dealers launched, doubling quarter-over-quarter in Q2. Dealers are now able to offer a seamless consumer buying experience powered by the ACV pricing engine our condition-adjusted model for vehicle valuation. Looking ahead, we are working 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 the price dealers can offer consumers. We are in the early stages of launching dealers on these new offerings and are very excited about consumer sourcing, because it offers attractive TAM expansion and strong unit economics for ACV by leveraging technology prior to incurring the cost of infecting vehicles. Moving to slide 16, I am pleased to share an update to our advanced buyer solution SAM which was formally launched last month. As a reminder, SAM provides dealers with specific and relevant notifications and intelligent auto bidding capabilities. SAM not only enhances the buyer experience in our platform, it also creates persistent demand price realization and ultimately higher conversion for our sellers. Following the July launch dealer adoption has accelerated with over 800 new dealers leveraging SAM in Q2. We believe, SAM will be a big growth driver for us as we expand its use cases and capabilities. On slide 17, I'll wrap-up on innovation with an update on APEX our next-generation data collection device that we introduced in March at our Analyst Day. APEX expands on ACV's existing AMS technology by incorporating upgraded audio capture capabilities and sensor detection including vibration displacement and ultrasonics. This more comprehensive data set, leads to a better understanding of the operating condition of a vehicle's engine and powertrain which increases dealer confidence while buying online. APEX also increased its inspection efficiency for our teammates and provides a better quality audio experience in our marketplace. This wireless device is integrated with our single inspection application and is live in select markets today with broad deployment planned later this year. So to wrap-up on innovation, we are very excited about our growing suite of data-enabled solutions and technology roadmap that expands our competitive model creates even more value for our dealer partners while improving margin to drive sustainable long-term growth. With that, let me hand it over to Bill, and take you through our financial results and how we're driving growth at scale.
