The European Used-Car Market — Understanding the Playing Field

AUTO1 is not a car company. It is a transaction machine for second-hand cars — a digital intermediary that buys used vehicles from consumers and fleets, reconditions a slice of them, and resells them to either professional dealers (its wholesale "Merchant" arm) or directly to consumers (its "Retail" arm, Autohero). To judge the stock, you first have to understand the arena it plays in: a vast, old, intensely fragmented, low-margin, and barely-digitised European used-car market.

The single most important idea for a newcomer: this is a penny-margin, high-velocity business. Nobody in used-car retail earns software-like margins on the cars themselves. The money is made on gross profit per unit (GPU) multiplied by volume, plus attached services (financing, logistics, warranties). Whoever can source cheaply, recondition efficiently, turn inventory fast, and bolt on finance wins. Everyone else burns cash.

1. The Arena: a €700bn market that is still mostly offline

Source: AUTO1 Capital Markets / Q1 2026 presentation, p.17 (market size per OC&C / Finaccord, 2019, EU27 + select European markets; includes B2B and financing transactions); company FY2025 Annual Report.

The numbers tell the whole story of why a company like AUTO1 can exist. Roughly 27.5 million used cars change hands in Europe every year, against a transaction value the industry sizes at around €700 billion (AUTO1's FY2025 annual report cites ~€600bn for the pure used-car retail layer; the larger figure adds B2B and financing flows). Yet the largest single player — AUTO1 itself — touches only 3.1% of relevant transactions, and the top 20 traditional retailers combined account for only ~6%. The other ~94% is a long tail of independent forecourts, single-location dealers, and private peer-to-peer sales.

That extreme fragmentation is the structural opportunity. Used cars trade roughly 2-3x as often as new cars are sold, the inventory is non-perishable but depreciating, and pricing is opaque — exactly the conditions under which a data-rich, pan-European aggregator can consolidate share. The catch, as the rest of this page shows, is that consolidating share in a penny-margin business requires enormous working capital and operational scale before profits appear.

2. How the money flows: the used-car value chain

A used car passes through several economic "stations" between its first and second owner. Profit can be captured at any of them, and the central strategic question for any operator is how many stations to own.

AUTO1 is vertically integrated: it owns the sourcing, the wholesale platform, the reconditioning, the retail brand, and the captive finance. Compare that to the two extremes of the industry. A pure marketplace (Auto Trader in the UK, Cars.com in the US) owns none of the stations — it sells listings and leads, never the car. A pure dealer group (AutoNation) owns physical stations but little technology. The economics of those models could not be more different, which is the next section.

This table is the heart of the business model. The Merchant (wholesale) arm is the volume engine — ~91% of the 842,000 cars AUTO1 moved in 2025 — selling a ~€8,700 car for roughly €960 of gross profit (about 11%). The Retail (Autohero) arm is the margin engine — a ~€17,100 car earns ~€2,555 of gross profit (about 15%), nearly 2.7x the per-unit gross profit of wholesale, but it ties up far more cash per car and grows off a much smaller base. The bull case for the whole sector is that online retail mix rises over time, dragging blended GPU up. The bear case is that retail's working-capital and reconditioning intensity keeps blended margins razor-thin for years.

3. Two business models under one roof: where the profits actually pool

Three very different businesses trade under the "Auto & Truck Dealerships" label, and lining up the operating margins of the listed comparables separates them cleanly.

Source: latest reported fiscal year per company filings (AUTO1 & Aramis FY2025 EUR; Carvana, CarMax, AutoNation, Cars.com USD; Auto Trader GBP). Margins are unitless and shown as reported.

The chart separates the industry into three economic species:

• Marketplaces (Auto Trader, Cars.com) carry essentially 100% gross margin because they never own a car — they sell listings. Auto Trader converts that into a stunning ~63% operating margin. This is the most profitable corner of the entire automotive-retail world, and it is the model AUTO1 is not in.
• Transactional retailers (Carvana, CarMax, Aramis, AUTO1) take inventory risk, so gross margins run 10-21% and operating margins are thin-to-negative. Carvana, after a near-death restructuring, is the standout at ~9%; CarMax sits around breakeven; Aramis and AUTO1 hover near 1%.
• Dealer groups (AutoNation) sit in between — asset-heavy physical networks earning mid-single-digit operating margins, propped up by parts, service, and finance.

The investment lesson is blunt: the used-car transaction business is structurally low-margin, and most of the durable profit in the broader sector pools in the asset-light marketplace layer. AUTO1's entire thesis is that scale plus vertical integration plus captive finance can lift a transactional model toward the kind of margins that justify a growth valuation. Whether that is achievable is the central debate the rest of this report adjudicates.

Source: latest reported fiscal-year filings for each peer. Figures kept in each company's reporting currency; revenue scale is not directly comparable across currencies but margins are.

Note the revenue scale: the US transactional players (Carvana, CarMax, AutoNation) each run €/$20-28bn of revenue versus AUTO1's €8.2bn — because in a transactional model, revenue is the full car price, so revenue mostly measures volume × ticket, not value created. This is why gross profit and GPU, not revenue, are the metrics that matter in this industry. A company can triple revenue by selling more cars at zero incremental margin; only GPU growth signals real economics.

4. A digitisation land-grab inside a flat market

The European used-car market itself barely grows — unit volumes track the car parc, scrappage, and the economic cycle, compounding at only low-single-digits (AUTO1 frames the long-term market unit CAGR at roughly +2%). The growth story is therefore not a rising tide; it is share migration from offline to online and from fragmented incumbents to scaled platforms.

Source: AUTO1 Group FY2016-FY2025 income statements (reported, EUR).

The two bars tell the industry's real dynamic. Revenue is lumpy — it fell in 2020 (COVID) and again in 2023 (used-car price deflation after the 2021-22 spike) — because revenue swings with both volume and used-car prices. But gross profit has compounded far more steadily, more than 4x from 2018 to 2025, because GPU is a spread the company controls regardless of headline car prices. That divergence — volatile revenue, resilient gross profit — is the signature of a well-run intermediary gaining share in a flat, cyclical market. It is also why this industry rewards GPU-and-units watchers and punishes revenue-watchers.

The fragmentation backdrop frames how much runway exists. If the largest player has 3.1% and the top 20 have ~6%, then the consolidation opportunity is measured in decades of share gains, not quarters — but it also means no single competitor can be ignored, because share is being contested forecourt by forecourt across 20+ countries.

5. The cycle, and what can go wrong

"Auto & Truck Dealerships" is classified consumer cyclical, and used-car intermediaries inherit three distinct risk cycles a newcomer must hold in mind:

Source: AUTO1 FY2025 Annual Report, MD&A (Price Index 138.2 at Dec-2025, +0.7% YoY) and risk-factor disclosures.

Two structural hazards sit on top of the cycles. First, inventory is depreciating stock: a used-car retailer that turns inventory slowly during a price decline takes real losses, which is why days-to-sale and turn velocity are existential KPIs in this industry — not vanity metrics. Second, electric-vehicle residual values are volatile and policy-sensitive: AUTO1 flags that EV resale values "remain volatile and sensitive to policy, taxation, and infrastructure maturity," a genuine and growing source of pricing risk as EVs flow into the second-hand market over the next decade.

The reassuring counterpoint: used-car demand is defensive relative to new cars. In a downturn, buyers trade down from new to used, which can cushion volumes even as ticket prices soften — a partial natural hedge that pure new-car dealers lack.

6. Regulation and technology: the forces reshaping the economics

Source: AUTO1 FY2025 Annual Report risk factors ("Regulatory Landscape") and business overview; intensity is the analyst's qualitative read.

Regulation is a moat as much as a risk. The European used-car business is governed not by one rulebook but by a patchwork of country-specific consumer-protection, warranty, registration, VAT, and administrative laws. AUTO1 explicitly calls this a "structural operational" complexity. For a single-country forecourt that complexity is a nuisance; for a pan-European platform that has already built the compliance, logistics, and tax machinery across 30+ countries, it is a barrier to entry — a new digital entrant must replicate that country-by-country apparatus to compete cross-border. The same logic applies to cross-border arbitrage: buying a car cheaply in one country and selling it where demand is higher is a core source of platform margin, but it depends entirely on harmonised transport and registration handling.

Technology is where the next margin leg is supposed to come from. Three shifts matter:

1. AI-based pricing. AUTO1 reports that ~90% of all cars are AI-priced, using proprietary pan-European demand data. In a market where pricing is opaque, a data advantage in pricing is the sourcing advantage — it lets the platform bid accurately and avoid over-paying.
2. Captive finance via securitisation. The industry increasingly funds inventory and lending off-balance-sheet through non-recourse ABS structures (AUTO1 carries no corporate debt; all long-term debt is non-recourse against ring-fenced assets). This lets a thin-margin retailer scale working capital without diluting equity — but it imports interest-rate and credit-loss risk.
3. Automation of reconditioning and overhead. The stated long-term lever is to halve overhead cost per unit through automation — the difference between a 1% and a 5%+ operating margin in a penny-margin model.

7. The investment lens: a flat market, a fragmented field, and a long climb to profit

Source: AUTO1 Capital Markets / Q1 2026 presentation, p.17 & p.30 (10% share and 5-9% Adj. EBITDA margin long-term targets); FY2025 Adj. EBITDA margin derived from reported €197.5m on €8,172.6m revenue.

Stripped to its essence, the industry case is a wager on three things resolving favourably:

(1) Online penetration of used-car transactions keeps rising from a low base. The car will increasingly be bought and sold through screens, not forecourts — and scaled platforms capture that migration.

(2) Scale + vertical integration + captive finance lift a structurally penny-margin model toward mid-single-digit operating margins. AUTO1 targets a leap from ~2.4% Adj. EBITDA margin and 3.1% share toward 5-9% margin and ~10% share — a tripling of share and a doubling-plus of margin.

(3) The cycle cooperates — used-car prices stay stable, rates ease, and EV residuals don't deliver a nasty surprise.

The honest summary: the European used-car market is enormous, durable, fragmented, and digitising — a genuinely attractive arena for a scaled consolidator — but the unit economics are brutal, the model is working-capital-heavy and cyclical, and the prize (marketplace-like margins) is exactly the thing transactional retail has historically failed to deliver. That tension — a large, structurally appealing opportunity versus a thin, capital-intensive, unproven path to profit — is the lens through which every subsequent tab of this report should be read.
