Thank you, Ernie, and thank you all for joining us today. Our fourth quarter highlighted the significant and sustainable progress we have made on our path to profitability. We set company records for fourth quarter and full-year total GPU and adjusted EBITDA, completing a year in which we improved adjusted EBITDA by nearly $1.4 billion and positioning us well for further adjusted EBITDA growth in 2024. As part of our earnings materials this quarter, we provide a detailed look at our fourth quarter and full-year results. I'll start by summarizing three key takeaways. First, our FY2023 results and Q1 2024 outlook resoundingly demonstrate the ability of our online sales model to generate significant adjusted EBITDA. Based on our Q1 outlook, we expect to generate significantly above $100 million of adjusted EBITDA, equating to significantly above $1,200 per retail unit sold. Despite declining used vehicle prices, industry volumes that remain below pre-pandemic levels and sizable costs of carrying capacity for future growth. Second, we are now beginning to demonstrate record adjusted EBITDA profitability while also showing early signs of growth. Based on industry data sources, we gained market share on a sequential basis in Q4 and our outlook calls for retail unit growth not only on a sequential basis, but also on a year-over-year basis in Q1 and in full-year 2024. Third, we have a unique and powerful infrastructure for significantly and efficiently scaling retail unit volume with excess capacity in our existing footprint to support multiples of profitable growth. We expect this growth to be paired with significant operating leverage as we leverage our underutilized overhead costs. Moving now to our fourth quarter results. As we previously discussed, our long-term financial goal is to generate significant GAAP net income and free cash flow. In service of this goal, our management team remains 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. Due to the dynamic nature of the current environment, we will focus our remaining remarks on sequential changes in these metrics. Retail units sold declined by 6% sequentially, in line with our outlook and better than the industry on a sequential basis. Total revenue was $2.424 billion, a decrease of 13% sequentially. In the fourth quarter, non-GAAP total GPU was $5,730, a sequential decrease of $666 driven primarily by the absence of non-recurring benefits, which positively impacted Q3 and seasonality. Non-GAAP retail GPU $2,970 in Q4 versus $2,877 in Q3, a new company record. Our strength in retail GPU came despite higher-than-normal fourth quarter depreciation and continues to be driven by fundamental gains in non-vehicle cost of sales, customer sourcing, inventory turn times and revenues from additional services, highlighting the value of our vertically-integrated business model. We expect non-GAAP retail GPU in Q1 to be similar to Q4, with the potential for upside. Non-GAAP wholesale GPU was $881 in Q4 versus $951 in Q3. Sequential changes in wholesale GPU were primarily driven by fourth quarter seasonality. We expect a sequential increase in wholesale GPU in Q1. Non-GAAP other GPU was $1,879 in Q4 versus $2,568 in Q3. Sequential changes in other GPU were primarily driven by selling a lower volume of loans in Q4 relative to retail units sold that in Q3, as well as lower premium on loan sales resulting from higher industry-wide loss expectations that we have since passed through to our pricing. We expect a sequential increase in other GPU in Q1. Non-GAAP SG&A expense was $376 million in Q4 versus $370 million in Q3. Sequential changes in non-GAAP SG&A expense were primarily driven by the absence of a small non-recurring benefit that impacted Q3 and small incremental expenses in Q4. Finally, adjusted EBITDA was $60 million in Q4, a new fourth quarter company record. I'll turn now to our first quarter outlook. While the macroeconomic and industry environment continues to be uncertain, looking toward the first quarter of 2024, we expect the following as long as the environment remains stable. One, we expect retail units sold slightly up on a year-over-year basis; and two, we expect adjusted EBITDA significantly above $100 million. Our confidence about driving significantly above $100 million of adjusted EBITDA is driven by our results so far this quarter. This outlook does not anticipate any material one-time benefits or costs in Q1. For FY2024, we expect to grow retail units sold and adjusted EBITDA compared to FY2023. We are excited about the path we are on, and we look forward to making continued progress toward our goal of becoming the largest and most profitable auto retailer. Thank you for your attention. We'll now take questions.
