Thank you, Ernie, and thank you all for joining us today. The first quarter was a milestone quarter for proving the long-term earnings power of our online retail model. We set company records on adjusted EBITDA and adjusted EBITDA margin. We achieved industry-leading adjusted EBITDA margin for the first time. We drove significant GAAP operating income, and we generated adjusted EBITDA that significantly exceeded capital expenditures and interest expense. Our results in Q1 were exceptional, but we also see significant opportunities to improve margins with scale and continued efficiency gains over time. We provide additional details on these opportunities in our shareholder letter. Turning to our first quarter results. We entered Q1 squarely focused on unit economics and profitability initiatives. Despite this focus, we saw strong customer demand in part due to several fundamental gains in conversion and customer experience that we made over the preceding quarters. Retail units sold increased by 16% year-over-year and 21% sequentially, reflecting significant market share gains on both a year-over-year and sequential basis. Revenue increased by 17% year-over-year and 26% sequentially. This unit and revenue growth was more than we targeted, given our continued focus on profitability initiatives entering the year. That said, our teams have handled it well and responded to increased sales while also demonstrating leverage on operations expenses. We are excited by this and believe there is more to come. Our growth in Q1 has had multiple impacts on our inventory. First, our results in Q1 demonstrated how efficient our nationally pooled inventory can be. In March, the average car we sold was only visible to customers on our website for 13 days before being purchased, nearing our all-time monthly low on this metric. Second, our inventory is currently smaller than we would like, resulting in less selection available to our customers. All else constant, we believe this is negatively impacting our sales volumes today. To respond, our teams have begun increasing production across the country. In the near term, our focus will remain on growing production to increase selection to more optimal levels for our customers. Our strong profitability results in Q1 were driven by meaningful fundamental improvements in GPU and SG&A expenses. In the first quarter, non-GAAP total GPU was $6,802, a sequential increase of $1,072 and a new first quarter record. Non-GAAP retail GPU was $3,211 versus $2,970 in Q4, a new company record. Our strength in retail GPU continues to be driven by fundamental gains and consistent performance in several areas, including nonvehicle cost of sales, customer sourcing, inventory turn times and revenues from additional services. Non-GAAP wholesale GPU was $1,153 versus $881 in Q4. Sequential changes in wholesale GPU were primarily driven by more favorable depreciation rates and first quarter seasonality. Non-GAAP other GPU was $2,438 versus $1,879 in Q4. Sequential changes in other GPU were primarily driven by more normalized loan sale volume relative to originations, lower securitization credit spreads and credit scoring and pricing optimizations, including credit tightening in Q4. Non-GAAP SG&A expense was $390 million versus $376 million in Q4. Q1 was an exceptional quarter for demonstrating the power of our model to leverage SG&A expenses. Retail units sold increased by 21% sequentially while non-GAAP SG&A expenses increased by less than 4%, leading to a nearly $700 reduction in SG&A expense per retail units sold. We continue to see opportunities for significant SG&A expense leverage over time and as we scale. Adjusted EBITDA was $235 million in Q1, a new company record. This result included small, onetime headwinds that were larger than any onetime tailwinds. It is important to note that the change in fair value of our Root Warrants does not impact adjusted EBITDA. Demonstrating the quality of our adjusted EBITDA, we also generated $134 million of GAAP operating income in Q1, a new company record. As mentioned previously, in Q1, we generated adjusted EBITDA that significantly exceeded capital expenditures and interest expense. This milestone means that in Q1, we officially achieved the goal we set out in May 2022 to drive significant positive cash flow after interest expense. Moreover, we achieved this goal at 360,000 units of annualized volume, in line with our expectations. Given our strong liquidity position and operating results, we currently plan to pay cash interest on our 2028 and 2030 senior secured notes on both semiannual payment dates in 2025, reducing long-term cash interest expense and supporting our plan to delever over time. Turning now to our second quarter outlook. We expect the following as long as the environment remains stable, a sequential increase in our year-over-year growth rate of retail units sold and a sequential increase in adjusted EBITDA. This outlook does not anticipate any material onetime benefits or costs. With our strong results in Q1 and outlook for Q2, we expect to comfortably deliver on our outlook of year-over-year growth in retail units sold and adjusted EBITDA for full year 2024. To conclude, our team's strong execution has positioned us well to pursue our financial goals. When we focused our growth, we joined Amazon, Google and Meta as one of the 4 fastest companies to join the Fortune 500. When we focused on profitability, we increased quarterly adjusted EBITDA by more than $500 million in under 2 years and catapulted to industry-leading margins. We are now focused on our long-term phase of driving profitable growth and pursuing our goal of becoming the largest and most profitable auto retailer and selling and buying millions of cars. We are excited about what's ahead. Thank you for your attention. We'll now take questions.
