CarMax ($KMX): Revenue Rose 6% but Gross Profit and Earnings Fell as Used-Car Margins Compressed, the Buyback Quietly Stopped, and Subprime Loan Exposure Jumped ~29%
CarMax's top line grew, but the growth was bought rather than earned: used-vehicle gross profit dollars fell as per-unit margins compressed, net earnings dropped nearly 12%, and the company leaned into subprime auto loans while quietly halting its buyback — a lower-quality quarter beneath a superficially solid revenue headline.

CarMax's top line grew, but the growth was bought rather than earned: used-vehicle gross profit dollars fell as per-unit margins compressed, net earnings dropped nearly 12%, and the company leaned into subprime auto loans while quietly halting its buyback — a lower-quality quarter beneath a superficially solid revenue headline.
⚠ Major Risks
- •Used-vehicle margin compression: used-vehicle gross profit fell to ~$501.4M from ~$554.2M even as used sales rose 4.7%, so used gross margin slipped from ~9.1% to ~7.8% — a volume-over-margin trade that signals limited pricing power.
- •Subprime credit expansion: Tier 2/Tier 3 receivables grew to $707.6M from $550.4M (~29%), the loan-loss allowance rose to 2.95% of loans ($475.0M) from 2.78%, and total past-due loans edged up to 5.20%.
- •Rising funding costs and securitization dependence: interest expense rose ~25% to $33.8M, CAF interest margin narrowed to $276.7M from $287.9M, and the company carries $16.08B of non-recourse notes reliant on warehouse and term-securitization markets.
- •Earnings deterioration: net earnings fell 11.8% to $185.6M and pretax earnings fell to $258.6M despite higher revenue; EPS held up better (-5% to $1.31) only because the share count is ~7% lower year over year.
- •Macro sensitivity: loss reserves hinge on a single macro scenario tied to U.S. unemployment and the Black Book used-vehicle index, so a downturn would pressure both vehicle demand and CAF credit losses simultaneously.
🔍 Accounting Red Flags
- ▲Net earnings of $185.6M versus operating cash flow of just $17.6M (down from $299.5M) — a wide divergence driven by a $518.5M build in auto loans held for sale; a funding-timing item, but it leaves reported operating cash flow very thin this quarter.
- ▲The loan-loss allowance is a judgment-heavy estimate built on a single macroeconomic scenario with a two-year reasonable-and-supportable window reverting to history over 12 months, while the book is actively shifting toward lower-credit Tier 2/3 loans.
- ▲The Level 3 residual-certificate fair value relies on an unobservable ~18% discount rate (immaterial at $4.1M, but a fully subjective input).
💰 Cash Flow Quality
Reported operating cash flow collapsed to $17.6M from $299.5M, though the drop is dominated by a $518.5M build in loans held for sale that should reverse as those loans are securitized.
- •Operating cash flow of $17.6M covered less than 10% of net earnings ($185.6M); the gap is almost entirely the auto-loans-held-for-sale buildup (from $100.5M to $619.0M on the balance sheet).
- •Management conserved cash: open-market buybacks effectively halted ($2.3M vs $204.0M a year ago) and capital expenditures were cut to $103.3M from $136.7M.
- •Non-cash provisions remain large — $95.6M net provision for loan losses and $26.2M for cancellation reserves — reflecting the credit-intensive captive-finance model.
- •Heavy reliance on securitization funding: $3.26B of non-recourse notes issued against $3.01B repaid during the quarter.
🏰 Competitive Position
As the nation's largest used-vehicle retailer with scale, a no-haggle brand, an omnichannel platform and a captive-finance flywheel, CarMax has a real but eroding edge in a fragmented, low-switching-cost market.
- +Largest U.S. used-vehicle retailer with national footprint and scale advantages in sourcing and reconditioning.
- +Captive CarMax Auto Finance arm captures additional spread and steady income (~$140M this quarter) and deepens the customer relationship.
- +Recognized no-haggle brand and omnichannel (online/in-store) buying experience in a market where most competitors are sub-scale.
- -This quarter's margin compression shows limited pricing power — the company had to thin used-vehicle spreads to move volume.
- -Highly fragmented, cyclical market with low switching costs and intense competition from franchised dealers and online rivals.
- -Profitability is increasingly leveraged to consumer credit, with growth tilting toward riskier Tier 2/3 borrowers.
The consensus read on this quarter is upbeat: net sales rose 6.2% to $8.01B, used-vehicle revenue climbed 4.7%, and EPS of $1.31 looks like only a modest 5% slip — evidence that retail demand is recovering. Invert it, and the numbers tell a harder story. Gross profit actually fell to $854.4M from $893.6M, because used-vehicle gross margin compressed from roughly 9.1% to 7.8% — used-vehicle gross profit dollars dropped about $53M even as the company sold more cars. CarMax moved metal at thinner spreads; this was volume bought with margin, not pricing power.
The second engine, CarMax Auto Finance, shows the same reach for growth. Tier 2/Tier 3 (lower-credit) receivables jumped ~29% to $707.6M, the loan-loss allowance rose to 2.95% of loans from 2.78%, and total past-due loans ticked up to 5.20%, even as CAF's interest margin narrowed and interest expense rose ~25%. So the profit cushion is being stretched at exactly the moment the credit book is moving down the quality spectrum.
Management's own actions confirm the caution. Open-market buybacks went from over $200M a year ago to essentially zero, and capex was trimmed — cash conservation that coincides with reported operating cash flow collapsing to $17.6M from $299.5M. Most of that collapse is a $518M build in loans held for sale that should reverse on securitization, so it isn't a solvency alarm, but the combination of a halted buyback and cut capex is a tell.
The one thing to watch: whether used-vehicle gross profit per unit stabilizes next quarter, and whether the fast-growing Tier 2/3 loan book holds up as it seasons. If margins keep thinning while subprime losses build, the revenue growth that headlines applaud will keep failing to reach the bottom line.
