Shares cratered 20% in after-hours trading Wednesday evening despite Carvana delivering what, on paper, looked like a blowout quarter. Q2 revenue hit $7.38 billion versus analyst estimates of $6.91 billion, net income surged to a record $513 million — up $205 million year-over-year — and vehicle sales jumped 38% to 197,325 units. The selloff tells a different story: investors who bid the stock up nearly 10% in the week before earnings were focused on profitability quality, not just top-line growth — and the numbers disappointed on that front.

  • The Profit-Per-Car Problem Spooked Investors

Total gross profit per retail unit fell 5.5% year-over-year to $7,014 , down from $7,426 a year earlier. The company's adjusted EBITDA margin dropped 2 percentage points from a year ago to 10.4% as expansion efforts accelerated.

Morgan Stanley had specifically flagged the need for "a quality beat in Gross Profit per Unit driven by company-specific operations." That didn't materialize. In plain terms: Carvana sold far more cars but made less money on each one.

  • Guidance Was Good But Not Good Enough

Carvana guided for full-year 2026 adjusted EBITDA of $2.7 billion to $3.0 billion, implying $1.3 billion to $1.6 billion in the second half.

That would top 2025's record $2.2 billion. But the midpoint of $2.85 billion sits below the ~$2.89 billion Wall Street consensus, and any shortfall risks compressing valuations by derailing the EBITDA margin trajectory toward management's 13.5% long-term target.

  • Volume Is Surging, but Costs Are Rising With It

The year-over-year GPU decline partly reflects the loss of roughly $100 per unit in tariff-related benefits that boosted results last year , plus lower shipping fees Carvana passed on to customers as delivery distances shrank — a customer-friendly move that cut into revenue per car.

Higher reconditioning costs also weighed on projections.

  • The Stock's History of Post-Earnings Swings Amplifies the Signal

In February 2026, CVNA fell 15% post-earnings; in October 2025, it dropped 14.3%. This is a stock where thin after-hours liquidity and a large short interest magnify moves. Insiders sold $28.5 million in shares over the prior three months , a detail that won't comfort nervous holders.

The bottom line: Carvana is growing faster than any auto retailer in the country, yet at ~800,000 units it still claims just 1.5% of the U.S. auto market. Whether investors treat that runway as a reason to buy the dip — or a reminder that scale is eroding margins — will define CVNA's next chapter.
