CarMax, Inc. vs Samsung Electronics Co., Ltd.: Strategic Comparison

This in-depth comparison examines CarMax, Inc. and Samsung Electronics Co., Ltd. across revenue, market value, business model, competitive positioning, and long-term growth strategy. Whether you are researching CarMax, Inc. on its own, evaluating Samsung Electronics Co., Ltd., or weighing the two companies side by side, the breakdown below highlights where each company leads and where the gap between CarMax, Inc. and Samsung Electronics Co., Ltd. is widest.

On the headline numbers, CarMax, Inc. reports annual revenue of $25.9B against ~$236.9B for Samsung Electronics Co., Ltd., while their respective market capitalizations stand at $9.1B and $1.33T. CarMax, Inc. is headquartered in United States and Samsung Electronics Co., Ltd. in South Korea, and those different home markets shape how each company competes.

CarMax, Inc.: CarMax fundamentally transformed the sleazy, high-pressure world of buying a used car in America. Before CarMax, buying a used car meant negotiating with a highly commissioned salesman in a plaid suit at an independent lot. CarMax disrupted this entirely by introducing a 'no-haggle, no-pressure' corporate retail model. With large, superstore lots across the country and a large online inventory, they applied the clean, standardized corporate efficiency of a Best Buy or Target to the chaotic used car industry, becoming the largest retailer of used cars in the US.

Samsung Electronics Co., Ltd.: Samsung Electronics, based in Suwon, is the flagship company of the Samsung Group and South Korea's most valuable listed company. It is the world's largest memory chipmaker and one of the two largest smartphone vendors. Its market value passed $1 trillion in May 2026 and was about $1.33 trillion in late September 2026, after its shares more than tripled in a year on AI memory demand. The company is led by co-CEOs Jun Young-hyun (semiconductors) and TM Roh (devices), with Jay Y. Lee as Executive Chairman.

CarMax, Inc. and Samsung Electronics Co., Ltd. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between CarMax, Inc. and Samsung Electronics Co., Ltd..

CarMax, Inc. business model: CarMax buys used vehicles from consumers (whether or not they buy a car), from dealers, and at auctions, reconditions the ones that meet its retail standard, and sells them at fixed prices online, in stores, or through a mix of both. Vehicles that do not meet the retail standard are sold to licensed dealers in CarMax's online wholesale auctions. On top of the vehicle margin, CarMax earns income from CarMax Auto Finance loans, fees from third-party lenders, and commissions on extended protection plans (EPP). In fiscal 2026, used vehicle sales were 80.0% of revenue, wholesale 17.4%, and other sales and revenues 2.6%; CAF contributed $562.7 million of income, reported separately from revenue.

Samsung Electronics Co., Ltd. business model: Samsung earns money from two groups of businesses. Device Solutions (DS) makes and sells memory (DRAM, HBM, NAND), System LSI chips such as Exynos processors and ISOCELL image sensors, and contract foundry manufacturing. In Q2 2026, DS produced ~$90.5 billion (KRW 127.5 trillion) of the company's ~$122 billion (KRW 171.5 trillion) revenue and ~$63.3 billion (KRW 89.2 trillion) of its ~$63.5 billion (KRW 89.5 trillion) operating profit. Device eXperience (DX) sells Galaxy phones, tablets, wearables, TVs, monitors and home appliances, plus network equipment. Separately consolidated subsidiaries add OLED panels from Samsung Display, sold to Apple and other phone makers, and automotive and audio electronics from Harman.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of CarMax, Inc. stack up against those of Samsung Electronics Co., Ltd..

CarMax, Inc. competitive advantage: CarMax's advantage is scale combined with vertical integration. It appraises and buys well over a million vehicles a year from consumers and dealers, which feeds both its retail lots and its own wholesale auctions, and it owns the reconditioning, logistics, pricing, and financing steps that pure marketplaces outsource. A national store network lets customers test drive, trade in, or pick up locally, while CarMax Auto Finance and third-party lenders let it approve most credit tiers at the point of sale. Edmunds adds an owned automotive research audience. No competitor combines retail, wholesale auctions, captive finance, and a brick-and-mortar footprint at the same scale.

Samsung Electronics Co., Ltd. competitive advantage: Samsung's edge is manufacturing scale and breadth. It is the largest memory producer and one of only three major DRAM makers, alongside SK hynix and Micron. That lets it capture pricing upswings like the 2026 AI-driven shortage. It also owns component businesses (memory, OLED through Samsung Display, image sensors) that sell to rivals as well as to its own Galaxy devices, so it earns money even when competitors' products win.

Future prospects matter as much as current results. The growth strategies below explain how CarMax, Inc. and Samsung Electronics Co., Ltd. each plan to expand from here.

CarMax, Inc. growth strategy: Keith Barr's 'Shift into GEAR' plan has four pillars: Great Offering (price competitively across demand cycles and grow saleable inventory), Easy Experience (connect digital tools with in-store service to lift conversion), Add Value (grow CAF and EPP profitability), and Run Lean (cut reconditioning, logistics, and SG&A costs). CAF's full-spectrum lending push is a central lever: in Q2 fiscal 2027 CAF financed 22% of Tier 2 volume versus 10% a year earlier. CarMax also continues to build stand-alone reconditioning and auction centers to support future volume.

Samsung Electronics Co., Ltd. growth strategy: Samsung's growth plan centers on AI memory: ramping HBM4 for Nvidia and AMD accelerators, developing HBM4E, and adding DRAM capacity at Pyeongtaek. In foundry it is pursuing 2nm gate-all-around production and building its Taylor, Texas fab to win customers from TSMC. On the device side it relies on Galaxy AI features, foldables and premium TVs to defend share against Apple and Chinese brands.

A closer look at the financial trajectory of CarMax, Inc. and Samsung Electronics Co., Ltd. rounds out the comparison.

CarMax, Inc.: CarMax's revenue is large but its margins are thin: in fiscal 2026 it booked $25.88 billion of net sales and operating revenues, $2.81 billion of gross profit (10.8%), $562.7 million of CAF income, and $2.45 billion of SG&A, leaving $247.3 million of net earnings ($1.68 per diluted share, or $2.91 adjusted). That compares with $26.35 billion of revenue and $500.6 million of net earnings in fiscal 2025, and a peak of $29.68 billion of revenue in fiscal 2023. The fourth quarter of fiscal 2026 included a $141.3 million non-cash goodwill impairment, wiping out the goodwill on the balance sheet. CarMax repurchased $631.8 million of stock in fiscal 2026, paused buybacks in Q4, and said in September 2026 it would resume them in Q3 fiscal 2027 after Q2 net earnings of $165.3 million on $7.9 billion of revenue.

Samsung Electronics Co., Ltd.: Samsung's earnings follow the memory cycle. Revenue fell from ~$215 billion (KRW 302.2 trillion) in 2022 to ~$184 billion (KRW 258.9 trillion) in 2023 during a chip downturn, then recovered to ~$214 billion (KRW 300.9 trillion) in 2024 and ~$237 billion (KRW 333.6 trillion) in 2025, when net income reached about $31.5 billion (KRW 44.3 trillion). In 2026, AI server demand created a memory shortage. Q1 operating profit of ~$40.6 billion (KRW 57.2 trillion) exceeded the full-year 2025 total, and Q2 reached ~$63.5 billion (KRW 89.5 trillion) on ~$122 billion (KRW 171.5 trillion) revenue. Higher memory costs also squeezed Samsung's own devices: the MX and Networks unit lost ~$497 million (KRW 0.7 trillion) in Q2 2026 on ~$23.6 billion (KRW 33.2 trillion) revenue.
