Thank you, Ernie, and thank you all for joining us today. Our first quarter results demonstrated significant progress on our path to profitability. We exceeded our goal of driving $100 million of non-GAAP SG&A reductions one quarter early, and we surpassed our previously communicated goal of greater than 4,000 GPU. In the first quarter, retail units sold totaled 79,240, a decrease of 25% year-over-year and 9% sequentially. Our decline in retail units sold, which we expected, was driven by four primary factors: one, reduced inventory size; two, reduced advertising; three, increased benchmark interest rates and credit spreads; and four, a continued focus on executing our profitability initiatives. Total revenue was $2.6 billion, a decrease of 25% year-over-year and 8% sequentially. Due to the dynamic nature of the current environment, we will focus our remaining remarks on sequential changes. As we've previously discussed, our long-term financial goal is to generate significant GAAP net income and free cash flow. In service of that goal, in the near term, our management team is focused on driving progress on a set of key non-GAAP financial metrics that are inputs into this long-term goal, including non-GAAP gross profit, non-GAAP SG&A expense and adjusted EBITDA. In the first quarter, non-GAAP total GPU was $4,796, a sequential increase of $2,129 driven by increases across all components. Non-GAAP retail GPU was $1,591 versus $632 in Q4. Retail GPU included a $593 benefit due to an adjustment to our retail inventory allowance. In addition, sequential changes in retail GPU were primarily driven by higher average days of sale, partially offset by wider spreads between wholesale and retail market prices, higher shipping revenue and lower reconditioning and inbound transport costs. Notably, we achieved our Q1 retail GPU despite selling vehicles that were, on average, more than 120 days old. Vehicles sold in Q1 that were less than 90 days old had retail GPU over 2,000, illustrating the benefit of normalizing inventory size and turning vehicles more quickly. Non-GAAP wholesale GPU was $1,236 versus $551 in Q4. Wholesale GPU included a $50 benefit due to an adjustment to our wholesale inventory allowance. In addition, we estimate that wholesale GPU benefited by $150 due to abnormal wholesale market appreciation in the quarter. Beyond those factors, sequential changes in wholesale GPU were primarily driven by higher wholesale marketplace volume. Non-GAAP other GPU was $1,969 versus $1,483 in Q4. Sequential improvement in other GPU was primarily driven by a greater volume of loans sold in the quarter compared to Q4. In Q1, we sold slightly less than a normalized volume of loans as a result of uncertainty in the securitization market in March. The GPU impact of this less-than-normalized sales volume was largely offset by higher interest income and other improvements, leading to an approximately normalized other GPU in Q1. In Q1, we made significant progress reducing SG&A expenses for the third consecutive quarter, reducing non-GAAP SG&A expense by $119 million sequentially, following a $60 million sequential reduction in Q4. These expense reductions were broad-based, including advertising, compensation and benefits, logistics and other SG&A. Non-GAAP SG&A expense per retail unit sold decreased by more than $900 sequentially in Q1, demonstrating significant operating leverage. Adjusted EBITDA loss was $24 million in Q1 or 0.9% of revenue. We expect to achieve positive adjusted EBITDA in Q2. After a strong quarter in Q1, we expect to drive greater than $5,000 of non-GAAP total GPU in Q2 as long as the macroeconomic and industry environment remains similar to Q1. Our strong GPU performance is powered by 3 fundamental drivers: driver number one, a more robust retail GPU model. We expect greater than $2,000 of non-GAAP retail GPU in Q2 driven primarily by our efforts to normalize inventory size, accelerate turn times and generate additional revenue from additional services. In FY '21, we generated approximately $1,700 of non-GAAP retail GPU. Since then, we've made fundamental improvements that we believe will drive higher retail GPU on a sustainable basis. First, we have continued to improve our customer vehicle sourcing with a higher share of retail units sourced from customers in Q1 2023 than in FY 2021. Second, we are generating more revenue from the unique services we offer our customers, including nationwide shipping and home delivery. Third, over time, we expect per unit reconditioning and inbound transport costs, excluding depreciation and amortization, to be below FY 2021 due to our continued focus on operating efficiency. Moving on to driver number two, expanded wholesale platform. We expect greater than $1,000 of non-GAAP wholesale GPU in Q2, split between Carvana's first-party wholesale vehicle sales and ADESA's third-party wholesale marketplace. In FY '21, we generated approximately $450 of non-GAAP wholesale GPU. Since then, we've made several fundamental improvements that we believe will drive higher wholesale GPU on a sustainable basis. First, in May 2022, we acquired ADESA, the second largest U.S. wholesale used vehicle auction marketplace. ADESA's wholesale marketplace generated significant gross profit in Q1 and will be a long-term addition to our total gross profit. Second, our acquisition of ADESA has improved the efficiency of our offering of buying cars from customers and selling them in the wholesale market. For example, since Q1 2022, we have reduced inbound transport costs on wholesale vehicles by approximately $200 per wholesale unit sold or approximately $90 per retail unit sold, supported by ADESA locations. Third, we continue to invest in our wholesale platform through product and process improvements with a continued goal of growing these businesses over time. Moving on to driver number three, strong finance and ancillary product execution. We expect greater than $2,000 non-GAAP other GPU in Q2, primarily driven by a normalization of loan sales volume. Since the beginning of Q2, we have sold or securitized approximately $1.3 billion of loan principal, an increase compared to Q1. In FY '21, we generated approximately $2,450 of non-GAAP other GPU. While we have not yet regained this level, in the medium term, we see a significant opportunity to increase other GPU by improving our cost of fund spread relative to mature securitization market participants and by continuing to expand our ancillary product platform. To summarize, our first quarter results and second quarter outlook reflect the return to our multitrack -- multiyear track record of driving GPU improvements. We believe the gains we are demonstrating in 2023 are sustainable and reflect the significant fundamental improvements we have made in the last 12 months. We also see further opportunities for more improvements in GPU in the future. Moving on to our second quarter outlook. While the macroeconomic and industry environment continues to be uncertain, looking toward Q2 '23 more broadly, we expect the following as long as the environment remains stable. On retail units, we currently expect a sequential reduction in retail units sold in Q2 compared to Q1 as we continue to normalize our inventory size, optimize marketing spend, make progress on our profitability initiatives -- and make progress on our profitability initiatives. On SG&A, we expect similar non-GAAP SG&A expense in Q2 compared to Q1. We continue to see significant opportunities to further reduce non-GAAP SG&A expenses over time. Finally, we expect to generate positive adjusted EBITDA in Q2, achieving the first step in our 3-step plan to generate positive free cash flow. On March 31, we had approximately $3.5 billion in total liquidity resources, including $1.5 billion in cash and revolving availability and $2 billion in unpledged real estate and other assets, including more than $1 billion of real estate acquired with ADESA. Our strong liquidity position, significant production capacity runway and our clear and focused operating plan positions us well on our path to achieve our goal of driving positive free cash flow and becoming the largest and most profitable auto retailer in the future. Thank you for your attention. We'll now take questions.
