The largest used car retailer in the US just reported Q4 results with a new CEO in the chair, a 57% adjusted EPS beat, a paused buyback, and a goodwill impairment that distorted the headline number.
Read on, and you get the breakdown of whether the $200 million cost-out target, the tariff-driven shift toward used vehicles, and the CAF lending recovery make this worth owning before the fiscal 2027 setup plays out.

The Q4 Headline Loss Was Accounting Noise – the Adjusted Beat Was 57%
CarMax, Inc. (NYSE: KMX) reported Q4 fiscal 2026 on April 14. Headline: net loss of $0.85 per diluted share. The reason: a $0.99 noncash goodwill impairment plus $0.20 in restructuring charges.
Strip both out and adjusted EPS was $0.34, beating the $0.22 consensus by 57%. Revenue $5.9 billion, beat estimates by 3%.
The stock fell 6% in premarket trading on the headline loss, which is exactly the kind of reaction that creates entry points if the thesis underneath is intact.
The goodwill impairment reflects the market cap declining below book value. It is an accounting adjustment, not a cash charge, and it does not affect operations.
Adjusted EPS $0.34, beat $0.22 consensus by 57%: The number that actually reflects the business.
$0.99 noncash goodwill impairment: No cash left the building. Just an accounting write-down.
Revenue $5.9B, beat estimates by 3%: Top line held up despite pricing pressure.
Combined unit sales hit 303,969, up 0.7%. Retail used comps declined 1.9%. That is the number to watch – sales momentum has not turned yet.
Action: Do not buy the headline. Buy the $0.34 adjusted beat if you are buying the FY2027 thesis. Enter $36 to $40, reassess if Q1 FY2027 adjusted EPS misses consensus.

Keith Barr Is the New CEO, and His Mandate Is Urgency, Not Patience
Keith Barr became President and CEO of CarMax effective March 16, 2026.
This is the first major leadership transition at the company in years, and his opening message on the Q4 earnings call was notably direct: “We are moving with urgency to improve execution, drive efficiencies, and sharpen our customer offering.”
That kind of language in a first earnings call is not boilerplate. It is a declaration of intent.
CarMax raised its SG&A exit-rate savings goal to $200 million by the end of FY2027, up from $150 million. That is a $50 million upgrade in Barr’s first quarter.
In-year savings get partially offset by bonus normalization and growth costs, but the exit rate is what matters for the FY2028 earnings run rate.
Keith Barr appointed CEO, March 16, 2026: First major leadership change in years.
SG&A savings target raised to $200M exit rate by FY2027: Up from $150M in his first quarter.
Barr inherited scale and a brand. Getting the cost base right while volumes recover is the operating leverage story.
Action: In June, if Barr updates the $200M target higher or cites specific milestones hit ahead of schedule, the efficiency program is outrunning expectations, and you add.

The Tariff Tailwind Is Structural, and It Sends Buyers Straight to Used
New vehicle tariffs raise average transaction prices. Buyers on the fence between new and used shift toward used.
CarMax sells more used cars than anyone in the US and manufactures nothing, so the tariff tailwind flows to it rather than through it.
This has happened before. Every time new vehicle affordability tightens, used vehicle demand picks up, and CarMax is the primary beneficiary at scale.
The company already increased its mix of older, more affordable ValueMax vehicles in Q4 to meet demand from budget-conscious buyers. That is a real-time response to the affordability shift happening right now.
New car tariffs raise prices, and used car demand follows: A direct and historical relationship.
Largest used vehicle retailer in the US: Scale advantage in the exact segment that wins from tariffs.
Gross profit per retail used unit fell $207 to $2,115 because CarMax cut prices to drive volume. You need volume to recover faster than margins compress.
Action: If Q1 FY2027 retail used comps turn positive, the tariff tailwind is real, and you add. A second consecutive quarter of negative comps means the pricing strategy is not generating volume, and you hold off.
CarMax Auto Finance: The Lending Arm That Can Swing EPS Hard
CarMax Auto Finance originates auto loans for CarMax buyers. CAF income was $143.7 million in Q4, with a 42.8% penetration rate on retail sales.
It is the single most important swing factor for the fiscal 2027 recovery thesis.
CAF income fell 9.8% in Q4 on a smaller receivable base and a higher provision of $74 million versus $68 million a year ago. The increase came from expanding into Tier 2 and Tier 3 credit, where penetration hit 25.6%.
The expansion is intentional, but credit quality is in a transition period. The net interest margin was 6.3%, up slightly, which tells you the spread is holding even as the mix shifts.
CAF income $143.7M in Q4: Down 9.8% but still generating meaningful earnings.
Penetration rate 42.8%: Nearly half of retail buyers are financing through CarMax’s own book.
Loan loss provision $74M vs $68M a year ago: Rising but contained, driven by deliberate Tier 2 and 3 expansion.
As the 2022 and 2023 vintages roll off, provisions normalize and CAF swings from headwind to tailwind.
Action: On the Q1 FY2027 call, if the loan loss provision is flat or declining versus $74M, the CAF normalization is tracking, and you hold.
Above $85M means the Tier 2 and 3 expansion is generating losses faster than modeled, and you reduce.
How CarMax Compares Against Carvana and the Franchise Dealers Right Now
Carvana trades at a premium multiple after its turnaround, but it is carrying real operational complexity and does not have CarMax’s physical footprint or financing scale.
The franchised dealers like AutoNation and Penske are actually hurt by tariffs because they are heavier in new vehicle sales, the exact segment feeling the pricing pressure. CarMax is the pure-play used vehicle beneficiary in a tariff environment.
On a forward basis, the multiple is in the mid-teens on FY2027 adjusted estimates.
For a business with 300-plus locations, a captive financing arm, and the dominant used car brand, mid-teens is not expensive if the cost-out and volume recovery both land.
Pure-play used position is the tariff advantage: New car dealers absorb tariff costs, and CarMax gets the displaced buyers.
Carvana has no comparable financing scale or physical footprint: Different risk profile and different unit economics.
The buyback pause is leverage-related, not a cash crisis. The $1.31 billion authorization is intact. When leverage normalizes, resumption follows. That moment has not arrived.
Action: When CarMax announces buyback resumption, add. That signal means leverage has normalized and cash generation is confirmed. Do not position early; wait for it.

The Risks Are Honest, and Two of Them Are Already Showing Up
Retail used unit comps declined 1.9% in Q4. That is not a background risk – it is a current reality. Management is cutting prices to drive volume, which is compressing gross profit per unit. Gross profit per retail used unit dropped $207 year over year to $2,115.
You are buying into a thesis that volume recovers faster than margins compress, and right now that equation has not tipped in your favor yet.
Consumer credit is the second largest risk. CAF has been expanding into Tier 2 and Tier 3, which means the book is more exposed to a consumer slowdown than it was two years ago.
The $74 million provision is manageable. A $100 million-plus provision in Q1 signals the expansion moved too fast.
Retail used comps down 1.9% in Q4: The volume recovery is the whole thesis. It has not started yet.
Gross profit per unit is down $207 year over year: Pricing for volume is working against margins.
Neither risk is fatal over 12 to 18 months. You are betting on direction. Q1 FY2027 is when you find out if the direction is right.
Action: Hard stop at $32. Negative comps and a provision above $85M in the same quarter mean both pillars are breaking. Exit without waiting.
Final Word: Messy Quarter, Real Thesis, and One Data Point Away From Confirmation
Noncash goodwill charge, 57% adjusted EPS beat, new CEO with a $200M efficiency mandate, and tariffs pushing buyers toward used cars. The setup is real. The confirmation is not here yet.
Buy partially. Size it for 12 to 18 months. Q1 FY2027 confirms. Hard stop at $32.
Setup Scorecard
Entry Window: $36 to $40. Do not chase it above $42 before Q1 FY2027 confirms the comp recovery.
Catalyst Watch: Q1 FY2027 earnings in June 2026 for retail used comp direction, CAF provision trend, SG&A progress update, and buyback resumption announcement.
Upside Setup: Retail used comps turn positive, CAF provisions decline toward $60M, SG&A savings exceed $100M annualized by mid-year. Stock rerates from mid-teens to high-teens forward earnings on FY2028 estimates. Target $50 to $55 over 12 to 18 months.
Downside Cushion: $5.9B quarterly revenue base, 300-plus location footprint, captive CAF financing at 42.8% penetration, $1.31B buyback authorization when leverage normalizes.
What Moves It Next: Q1 FY2027 retail used unit comps, CAF income and provision direction, tariff impact on new vehicle transaction prices in April and May, and any SG&A milestone update from Barr.
