Can Starboard Squeeze Meaningful Margin from CarMax's 2.5% EBIT Margin Without Disrupting the Omnichannel Pivot?
Event Date: March 11, 2026 — Starboard Value LP nominates two directors for CarMax's 2026 Annual Meeting
What Happened
Starboard Value, the activist investor known for its operational playbook at companies like Darden Restaurants and Papa John's, has formally nominated two directors to CarMax's board ahead of the 2026 Annual Meeting. The move follows months of engagement and lands at a moment of acute vulnerability: CarMax is without a permanent CEO, its EBIT margin sits at 2.5% — roughly half that of dealer peers — and the stock has lost 41% over the past year.
CarMax responded that it "has been taking the necessary steps to ensure that this business delivers on its potential," pointing to an ongoing board-led CEO search and $150 million SG&A reduction initiative. But Starboard's filing raises a pointed question: can a cost-focused activist extract meaningful margin improvement from a business that has spent years and billions building an omnichannel platform?
The Margin Gap
| Metric | KMX (TTM) | AutoNation (AN) | Lithia (LAD) |
|---|---|---|---|
| EBIT Margin | 2.5% | 4.5% | 4.1% |
| Gross Margin | 11.3% | 17.7% | 14.9% |
| ROE | 7.5% | 27.7% | 12.4% |
| ROIC | 3.1% | 9.9% | 7.3% |
| Revenue Growth (TTM) | 0.1% | 3.2% | 4.0% |
The comparison is stark. CarMax's 2.5% EBIT margin trails AutoNation by nearly 200 basis points and Lithia by 160 basis points. In FY2025, CarMax generated $789 million of operating income on $28.2 billion in revenue. Closing even half the margin gap to peers — roughly 100 basis points — would represent an incremental $282 million in EBIT, or roughly a 36% improvement.
But the gap isn't purely a cost story. CarMax's gross margin of 11.3% already trails AN's 17.7% substantially, reflecting CarMax's no-haggle, high-volume, used-only model versus franchise dealers that benefit from higher-margin new car sales, parts, and service operations. The controllable lever is SG&A.
The SG&A Question
CarMax spent $2.44 billion on SG&A in FY2025, or 8.6% of revenue. The company has already committed to $150 million in SG&A savings by FY2027 — roughly a 6% reduction — with a 30% workforce cut at its Customer Experience Centers in Q3 FY2026 as a first step.
The trajectory, however, is moving in the wrong direction on a per-unit basis. Q3 FY2026 showed SG&A of $581 million against $6.2 billion in revenue (9.3%), up from Q3 FY2025's $576 million against $6.7 billion (8.6%). Revenue declined 7% year-over-year while SG&A barely budged, exposing the operating deleverage problem that activists love to target.
Management has leaned into AI-driven efficiency — its "Sky" tool improved consultant productivity by 24% and containment rates by 30% — but these gains have yet to flow through to bottom-line margins in a declining volume environment.
The Omnichannel Dilemma
This is where Starboard's margin thesis collides with CarMax's strategic identity. The company has invested heavily in its omnichannel platform: 80% of retail sales are now digitally supported, and the company just launched a ChatGPT-based shopping experience — a first for U.S. auto retail. Net Promoter Scores are at their highest since the digital rollout began.
CarMax's omnichannel infrastructure carries real costs — technology, logistics, and the nationwide inventory network that enables online-to-store delivery. Carvana, the pure-digital competitor, demonstrates what aggressive cost focus looks like: it has achieved a 9.3% EBIT margin, but only after near-bankruptcy, massive debt restructuring, and draconian cost cuts that would be culturally alien to CarMax.
Starboard's playbook typically involves SG&A rationalization, improved procurement, and board-level governance changes. At CarMax, the risk is that cutting too deep into the omnichannel buildout undoes the competitive moat that justifies the company's market position against both traditional dealers and digital natives like Carvana.
What the Numbers Suggest
CarMax's FY2025 results show a business that has stabilized revenue at ~$28 billion but lost its profit momentum:
| Fiscal Year | Revenue ($B) | EBIT ($M) | EBIT Margin | EPS |
|---|---|---|---|---|
| FY2022 | $33.2 | $1,586 | 4.8% | $6.97 |
| FY2023 | $31.1 | $757 | 2.4% | $3.03 |
| FY2024 | $28.2 | $766 | 2.7% | $3.02 |
| FY2025 | $28.2 | $777 | 2.8% | $3.21 |
EBIT has flatlined near $770 million for three consecutive years after peaking at $1.6 billion in FY2022. The $150 million SG&A target, if fully achieved, would lift EBIT margin to roughly 3.3% — still well below the 4%+ level peers command.
Investment Implications
The Bull Case for Starboard's Involvement
- CEO search catalyst: Board representation gives Starboard influence over the permanent CEO hire, likely pushing for a more operationally focused leader
- Incremental SG&A beyond $150M: Starboard could push for $250-300M in total cost reductions, targeting the back-office and marketing spend that management cited as elevated in Q3
- Capital allocation discipline: KMX repurchased shares at a $1.74 billion authorization pace — Starboard may redirect capital toward debt reduction given $19.4 billion in total debt and a 15.5x net debt/EBITDA ratio
The Bear Case
- Volume risk: CarMax's Q3 FY2026 showed retail unit comps down 6.3% — cost cuts in a declining volume environment can accelerate the slide
- Omnichannel disruption: Reducing investment in digital capabilities hands Carvana and franchise dealers a competitive opening
- No-haggle model ceiling: CarMax's pricing transparency inherently caps gross margins below franchise dealers who negotiate and bundle F&I products more aggressively
What's Next
- 2026 Annual Meeting (likely June-July 2026): Shareholders vote on Starboard's two nominees — the proxy fight's outcome will signal whether the market wants operational change or strategic continuity
- Permanent CEO announcement: The board search is underway with "urgency" — Starboard's presence likely accelerates the timeline and shapes the candidate profile
- Q4 FY2026 results (March/April 2026): Will show whether the $150M SG&A initiative is gaining traction and if the volume declines have bottomed
The core tension is clear: CarMax's 2.5% EBIT margin leaves meaningful room for improvement, but the path from 2.5% to 4%+ requires either substantial volume recovery or cost cuts that risk undermining the omnichannel infrastructure CarMax has spent years building. Starboard's track record suggests it will push for the latter. Whether that creates or destroys long-term value depends on where the cuts land.
