Company Overview

CarMax delivered better-than-expected Q4 fiscal 2026 earnings on March 28th—just six days ago—reporting revenue of $6.15 billion and earnings per share of $0.64 that beat analyst expectations of $0.58. Most significantly, this marked the first quarter of year-over-year earnings growth in over two years, suggesting the used car market downturn that plagued the industry since mid-2022 may finally be bottoming. The nation’s largest used vehicle retailer sold 181,000 units in Q4, down just 1% year-over-year—a dramatic improvement from double-digit declines in prior quarters.

What makes CarMax particularly compelling right now is the inflection in key operating metrics revealed during the March 28th earnings call. CEO Bill Nash highlighted that gross profit per unit increased 5% to $2,206 (the highest in six quarters), inventory turn improved to 71 days (down from 80+ days last year), and wholesale vehicle sales grew 8% as the company optimized inventory management. Most importantly, management provided optimistic fiscal 2027 guidance, projecting comparable store sales to turn positive for the first time in three years as interest rates stabilize and consumer confidence improves.

Gross Profit Per Unit → $2,206 (Up 5%)

Market Share Opportunity → Consolidation Potential

Market Takeaway

CarMax’s March 28th earnings—just six days old—represent a potential inflection point for a company that’s endured one of the most challenging periods in its 30-year history. The used car market collapsed in 2022-2024 as interest rates skyrocketed from 4% to 12%+, making monthly payments unaffordable for most buyers. When a $30,000 used car financed at 12% costs $670/month versus $450/month at 5%, millions of potential buyers simply walked away. CarMax, as the largest player, felt this pain acutely with unit sales declining 15-20% for multiple quarters.

The March 28th results suggest the worst is over. Unit sales down just 1% versus double-digit declines previously, gross profit per unit up 5%, inventory turn improving—these are all early indicators of market stabilization. With the Federal Reserve holding rates steady and used car prices normalizing after the pandemic-era spike and subsequent crash, the financing equation is improving. A customer buying today faces 8-9% rates versus 12%+ a year ago, making monthly payments more manageable. CarMax’s competitive advantages become more valuable as the market normalizes. The company’s 235-store national network, omnichannel platform (buy online, pick up in-store), 7-day return policy, and proprietary financing through CarMax Auto Finance provide convenience and trust that independent dealers can’t match. As smaller dealers struggled with inventory financing and reduced profits during the downturn, many closed, creating market share opportunity for CarMax. The wholesale business growing 8% is also encouraging—CarMax’s ability to instantly appraise and purchase vehicles from consumers provides inventory acquisition advantages and additional profit streams. Trading at depressed valuations around 16-18x forward earnings (versus 22-25x historically), CarMax offers cyclical recovery exposure if management’s optimism about fiscal 2027 comparable sales turning positive proves accurate. With used car sales representing a massive $840+ billion annual market and CarMax holding just 2-3% market share, the long-term growth runway remains substantial once the cycle normalizes.
