Thank you, Ernie, and thank you all for joining us today. Unless otherwise noted, all comparisons will be on a year-over-year basis. 2025 was an exceptional year for Carvana. We entered the year focused on 3 key objectives: one, delivering significant growth in retail units sold and adjusted EBITDA; two, driving fundamental gains in unit economics and customer experience; and three, developing foundational capabilities. By these measures, 2025 was a resounding success. In full year 2025, we grew retail units sold by 43% to a record 596,641. We integrated 10 additional ADESA locations, we expanded our digital auction capabilities nationwide, we reached multiyear highs on customer Net Promoter Score, and we increased adjusted EBITDA margin to a record 11%, again, making us the fastest-growing and most profitable company in our industry. Moving to the fourth quarter. Retail units sold totaled 163,522 in Q4, an increase of 43% and a new company record. Revenue was $5.603 billion, an increase of 58%. Revenue growth exceeded retail units sold growth primarily due to traditional gross revenue treatment for certain vehicles acquired from a large retail marketplace partner. Consistent with past quarters, our growth in the fourth quarter was driven by our 3 long-term drivers of growth: a continuously improving customer offering, increasing awareness, understanding and trust and increasing inventory selection and other benefits of scale. The fourth quarter marked our eighth consecutive quarter of industry-leading retail unit growth and unit economics. Non-GAAP retail GPU decreased by $255 primarily driven by higher non-vehicle costs, lower shipping distances flowing through to customers in the form of lower shipping fees and higher retail depreciation rates. Non-GAAP wholesale GPU decreased by $148 primarily driven by faster growth in retail units sold than wholesale marketplace units. Non-GAAP other GPU increased by $49 primarily driven by improvements in cost of funds and higher finance and VSC attach rates, partially offset by our decision to give back to customers in the form of lower interest rates. Since our last reporting, we again expanded our loan sale platform by entering into a fourth loan purchase agreement with a long-standing loan partner for up to $4 billion of loan purchases through December 2027. This brings the total of our new partner loan purchase agreements to $12 billion over the next 2 years in addition to $6 billion with Ally through October 2026. Q4 was another strong quarter for levering SG&A expenses. Our 43% growth in retail units sold led to a $340 reduction in non-GAAP SG&A expense for retail units sold, including a $57 reduction in operations expenses and a $344 reduction in overhead expenses. Advertising expense increased by $83 per retail unit sold as we continue to invest in building awareness, understanding and trust of our customer offering. With approximately 1.6% market share of the used vehicle retail market compared to approximately 20% e-commerce adoption in nonautomotive retail verticals, we believe we are in the early days of customer awareness and adoption of our model. We continue to see opportunities for significant SG&A expense leverage over time and as we scale driven by both continued improvements in operational expenses as well as leverage in the fixed components of our cost structure. Net income was $951 million, an increase of $792 million. Net income was positively impacted by a noncash benefit of $618 million, including a net noncash tax benefit of $685 million partially offset by a $67 million reduction in the fair value of warrants. Net income margin was 17.0%, an increase from 4.5%. Adjusted EBITDA was $511 million, an increase of $152 million and a new Q4 record. Adjusted EBITDA margin was 9.1%, a decrease from 10.1% primarily driven by increased retail revenue per unit resulting from the traditional gross revenue treatment mentioned previously. GAAP operating income was $424 million or 83% of adjusted EBITDA, an increase of $164 million and a new Q4 record. 2025 was a strong year for our balance sheet. We ended 2025 with $2.3 billion of cash and equivalents, retired $709 million of corporate notes, and reduced our net debt to trailing 12-month adjusted EBITDA ratio to 1.3x, our strongest financial position ever. As discussed in prior quarters, we remain committed to driving toward investment-grade quality credit ratios over time. In 2026, we plan to maintain our 3 key objectives from 2025, while placing additional weight on driving significant profitable growth at scale. Looking forward, assuming the environment remains stable, we expect significant growth in both retail units sold and adjusted EBITDA in full year 2026, including a sequential increase in both retail units sold and adjusted EBITDA in Q1 2026. In conclusion, Q4 represented another strong quarter, closing out our best year in company history. We remain excited about progressing toward our goals of becoming the largest and most profitable auto retailer and buying and selling millions of cars. Thanks for your attention. We'll now take questions.
