CarMax Inc. KMX
CarMax's omnichannel flywheel is intact but stalled; new CEO Keith Barr can unlock value by fixing digital conversion, reconditioning costs, dynamic pricing, and SG&A discipline.
Thesis
Starboard, a ~$350 million shareholder, congratulates incoming CEO Keith Barr and lays out an operational playbook for CarMax (KMX). The firm argues CarMax's omnichannel model — anchored by physical stores and ~90% consumer-sourced inventory — should be a structural advantage, but execution has lagged: the digital trade-in flow loses conversion to nimbler competitors, in-store reconditioning is under-automated (with >$300/unit savings available), and rigid gross-profit-per-unit pricing rules drove share losses in 2025-26. Starboard urges modest $100-$300 per-vehicle price reductions paired with real-time dynamic pricing, and a zero-based SG&A reset targeting 70-75% of gross profit (vs. franchise-dealer peers near 71.9%). It also flags CarMax Auto Finance as conservatively managed, with room to thoughtfully expand into adjacent credit tiers while protecting the pristine balance sheet (~$42/share tangible book).
SCQA
CarMax is the largest US used-car retailer with a differentiated omnichannel model, ~90% consumer-sourced inventory, ~$42/share tangible book, and a NPS-leading customer franchise — trading near book at ~8x NTM EBITDA.
Recent performance has fallen well short of potential: digital conversion lags peers, reconditioning is under-automated, rigid per-unit gross-profit targets caused share losses, and SG&A drifted above the ~71.9% peer-average ratio of gross profit.
Starboard urges Keith Barr to streamline the digital trade-in/sell flow, cut >$300/unit reconditioning costs, adopt dynamic pricing with $100-$300 price cuts, run a zero-based SG&A reset to 70-75% of gross profit, and selectively grow CAF.
Reactivating the scale flywheel through buying, reconditioning, selling, pricing and SG&A discipline can close the gap between current performance and long-term potential, expanding margins beyond the ~8x NTM EBITDA multiple while protecting the pristine balance sheet.
The three reasons
- 1
Digital front-end friction is killing conversion despite top-of-funnel demand
- 2
SG&A bloated to >75% of gross profit vs. ~71.9% peer average — zero-based reset needed
- 3
Rigid per-unit gross-profit targets caused share losses in volatile 2025-2026 markets
Primary demands
- Simplify and streamline the digital trade-in/buying experience to lift conversion
- Optimize embedded reconditioning operations and pursue >$300/unit cost savings
- Adopt a dynamic, data-driven pricing framework instead of rigid gross-profit-per-unit targets
- Run a zero-based SG&A review and target SG&A at 70-75% of gross profit (preference 70%)
- Thoughtfully expand CarMax Auto Finance into adjacent and slightly lower-credit tiers while protecting the balance sheet

Notes
Public welcome letter from Jeffrey Smith / Starboard Value to incoming CarMax CEO Keith Barr, dated March 10, 2026. Tone is unusually collaborative for an activist letter — congratulatory framing, explicit acknowledgement that meetings have not started, and a structured operational to-do list (digital front end, reconditioning, selling, pricing, SG&A, CAF). No proxy threat, no named villain, no slides or charts — pure prose letter on Starboard letterhead. Stake quantified in dollars (~$350M) but no percent ownership disclosed. Peer set listed in footnote: CVNA, ABG, AN, GPI, LAD, PAG, SAH. Classified as initial_thesis because this is the first public Starboard letter following the CEO transition; could also be read as follow_up if part of a longer existing campaign — folder context suggests this is the opening salvo to the new CEO.
