CarMax earnings create a buying opportunity in Carvana stock

Carvana CVNA shares opened in the “red” this morning in sympathy with peer CarMax (KMX) whose Q1 earnings signaled margin compression, stubbornly weak volumes, and rising acquisition costs.

But a compelling case can be made that the market is lazily painting both companies with the same brush, ignoring the fundamental structural differences between how they operate.

Here’s why the sell-off in Carvana stock today is unwarranted and may actually be an opportunity for long-term investors to load up on a quality name at a discount.

Market share dominance warrants buying Carvana stock

The most obvious flaw in the “sympathy sell-off” logic is that Carvana and CarMax are on entirely different growth curves right now. 

KMX saw its comparable-store used units slip 0.8% this quarter – continuing a long-running trend of sluggish retail volume.

The company is stuck in a mature, brick-and-mortar bottleneck.

CVNA, on the other hand, is capturing massive market share: In its latest reported quarter, Carvana posted an explosive 40% year-on-year growth in retail units, selling over 187,000 cars. 

CarMax explicitly said today that it had to cut prices and sacrifice margin just to “try” and prop up stagnant volumes, but Carvana is pulling in hyper-growth numbers without having to trim its unit economics.

So, a margin squeeze born out of KMX operational stagnation doesn’t automatically mean Carvana is experiencing the same friction – that’s what makes CVNA shares worth buying on the dip.

CVNA shares offer a more attractive GPU structure

Investors panicked also because CarMax’s retail gross profit per unit (GPU) tanked by $230 in the first quarter to $2,177.

However, treating this as a death sentence for CVNA ignores how much more vertically integrated and multi-layered its GPU structure really is. 

KMX’s profit model is tightly tethered to the traditional spread between wholesale acquisition and retail sticker price.

When wholesale acquisition cost pops (as they did this quarter, driving CarMax’s average selling price up by $1,168), the company’s margins get crushed.

But CVNA’s total GPU isn’t just about the metal. It generates “highly optimized” revenue streams from proprietary digital financing, gap insurance, extended warranties, and a vertically integrated logistics/reconditioning network.

In Q1, the company delivered an industry-leading 10.4% Adjusted EBITDA margin.

So, Carvana shares are attractive because they’re structurally built to absorb fluctuations in vehicle acquisition costs far better than KMX’s legacy model.

Should you load up on Carvana Co today?

CarMax’s new chief executive, Keith Barr, spent much of the earnings call talking about operational inefficiencies, explicitly mentioning that KMX moves roughly 2 million cars annually via transfers but suffers from “too many unproductive transfers.”

Simply put, the company is weighed down by heavy fixed overhead: physical dealerships, massive localized inventory footprints, and regional logistics inefficiencies.

When foot traffic slows down, those fixed costs bleed them quickly. But Carvana’s “digital-first”, centralized hub-and-spoke model allows for much higher variable cost elasticity.

CVNA stock looks compelling as it routes fulfillment dynamically through digital platforms and centralized reconditioning centers; it doesn’t face the same “unproductive localized overhead” that CarMax is currently scrambling to restructure.
