# AutoNation (AN) Q3 2026: pre-earnings channel check Canonical URL: https://ai.marketcheck.com/investor/an-q3-2026 Pre-earnings channel check · Dealer group · published Oct 21, 2026 · 25 min read · reported Thu, Oct 29, 2026 ## What the report says North American Vehicle Transaction Signal - Signal: Neutral. Confidence: Medium. AutoNation's new-vehicle sales moved with the market. In our data they fell 3.1% from a year ago (5.2% at the stores AutoNation owned through both years), against a 3.0% fall for the whole new market, and by September they were up 0.8%. Used sales fell 7.2% (8.1% same-store) against 3.5% for the used market, but our count has run 4 to 5 points below AutoNation's own reported used change in both earlier quarters this year, so that shortfall sits inside our measurement error. New cars sold closer to sticker than a year ago, by more than franchise dealers overall managed, while used cars came off their first asking price by as much as a year ago even as franchise dealers overall cut less. The lots are heavier: nearly a third of new stock had waited over 90 days at its selling store, and used stock rose 11% from a year ago after setting aside cars listed more than 180 days at the same store as service loaners, taking used Market Days Supply to the top of its typical range, ahead of the off-lease returns management expects. Gross profit per car, financing, service, the captive lender and the share count are outside our data and can move the company's quarter a full tier either way.
