CarMax, Inc.

KMX

FAVORABLE

May 27, 2026

Research Conclusion

At $41.57/share, CarMax trades at ~6.8x forward EV/EBITDA, a trough multiple typical of a distressed cyclical rather than the nation's largest used-car retailer with embedded $16B+ captive finance operation. The stock is priced for simultaneous failure on all execution levers. Our probability-weighted analysis yields ~$79/share expected value—roughly 90% upside from current levels. The base case (45% probability) implies $80–$110 over 2–3 years as CEO Keith Barr's restructuring materializes and the cycle turns. The bear case (25% probability) represents fair value with zero execution credit. The asymmetry is favorable. The primary risk is not whether CarMax is cheap (it is, by almost any framework), but whether the turnaround takes 2 or 5 years and whether Carvana closes the GPU gap further. Constructive at current price with medium confidence, 2–3 year horizon.

Company Overview & Moat Assessment

CarMax, Inc. (NYSE: KMX) is the nation's largest used-vehicle retailer, operating 256 stores across 110 U.S. television markets as of February 28, 2026. Founded in 1993 and spun off from Circuit City in 2002, CarMax pioneered the no-haggle used-car model. The company sells ~780,000 retail used vehicles per year (~2% of the 40M-unit U.S. used car market), purchases nearly 1 million vehicles per year directly from consumers, and operates a wholly-owned captive finance subsidiary, CarMax Auto Finance (CAF), which holds ~$16.4B in auto loan receivables. Revenue of $25.9B in FY2026 splits ~80% used vehicle sales, ~17% wholesale, and ~3% services/EPP. CAF generates ~$563M in annual segment income—economically the most critical earnings contributor at ~70% of total adjusted net income. The stock trades at ~14x adjusted EPS and ~0.98x book value.

▲ Bull Case

  • ◆SG&A savings delivery: $200M annual savings target materializes by FY2028, adding ~$1.04/share to adjusted EPS, pushing EPS toward $4.25+ in FY2027 and $6.50+ in FY2028 as volume and GPU improve.
  • ◆Rate normalization + CAF expansion: 100–150bps in Fed rate cuts by FY2028 drive used car affordability, pushing comp units +3–5%; CAF penetration moves toward 50% target, adding $135–160M incremental annual CAF income.
  • ◆Multiple re-rating to peers: As ROIC recovers above WACC (projected FY2028–FY2029), stock re-rates from 6.8x to 9.5–11x EV/EBITDA in line with AN/LAD peers at 10.8x–13.2x, implying $120–$140/share.

▼ Bear Case

  • ◆SG&A execution miss: Barr delivers only $50–75M of $200M target; cultural resistance and automotive complexity overwhelm IHG playbook; EPS trajectory stays near $2.25–2.50 through FY2028.
  • ◆GPU structural erosion: Carvana's superior per-unit economics (GPU >$3,000 vs. KMX $2,253) drive pricing pressure; used GPU falls to $2,100–2,150 as CarMax struggles to differentiate in commodity market.
  • ◆CAF credit deterioration: Provision for loan losses stays elevated at $420–450M as Tier 2/3 borrowers underperform; CAF income flat to declining despite penetration gains; credit risk elevated at 14% average rates.
Primary Debate on Wall Street

“The central Street debate: deep-value turnaround or value trap? Bulls (1 Strong Buy, 2 Buy of 13 analysts) argue CarMax is at extreme historical discount with new CEO catalyzing efficiency, tariff tailwind improving demand, and embedded CAF franchise chronically underappreciated. Average bull target: $60–$90. Bears (1 Sell, 2 Strong Sell of 13 analysts) argue Carvana has structurally shifted unit economics; GPU will compress; 30-year no-haggle advantage is table stakes; CEO execution from hospitality outsider is serious risk. Consensus cluster (7 Hold of 13) agrees stock is fairly valued at current levels—priced for bear case but lacking near-term catalysts for re-rating. Average target: $40–$60. Street consensus FY2027E EPS $2.55–$3.48 (center $2.75) is MORE cautious than our base case ($3.50), reflecting our assumptions on faster CAF provision normalization and SG&A savings beginning FY2027.”

Top Catalysts
  • ◆Q1 FY2027 earnings (June 2026): First full quarter under CEO Barr; SG&A/unit trajectory and savings execution confirmation. HIGH impact, will re-rate stock $5–$15 either direction.
  • ◆SG&A savings on track: SG&A/unit declining below $1,800 and path to $1,700 exit validates $200M target delivery. HIGH impact, Q1–Q3 FY2027.
  • ◆Fed rate cuts to ≤3.5%: Material improvement in used car affordability and comp unit rebound across all 256 stores. HIGH impact, FY2028.
  • ◆CAF penetration >44%: Evidence of Barr prioritizing finance utilization and CECL-driven income growth. MEDIUM impact, FY2027–FY2028 with 3–5 quarter lag.
  • ◆Tariff-driven volume acceleration: Industry data confirming sustained +3–5% used car unit growth supporting bull case. MEDIUM impact, Q2–Q4 FY2027.
Top Risks
  • ◆SG&A savings execution miss: Barr delivers only $50–$75M of $200M target due to cultural resistance and automotive complexity. HIGH severity, 40–50% probability.
  • ◆GPU structural erosion: Carvana's superior per-unit economics drive compression below $2,100, signaling moat collapse not cyclical trough. HIGH severity, 25–35% probability.
  • ◆CAF provision spike above $450M: Tier 2/3 credit deterioration worsens, impairing most critical earnings driver and killing CAF expansion thesis. HIGH severity, 25% probability.
  • ◆Prolonged high interest rates above 4%: Rate normalization delayed 1–2 years, pushing demand recovery beyond base case horizon. HIGH severity, 40–50% probability.
  • ◆Carvana competitive disruption: CVNA achieves 1.2M+ units with $3,500+ GPU, definitively winning model war and invalidating turnaround thesis. MEDIUM severity, 30–40% probability.
