China's EV Makers Face Margin Collapse as Battery Giants Capture the Value Chain
Automakers posted RMB 1,954 billion (US$271.4 billion) in industry profit in H1 2026—down 20% year-on-year—even as revenue grew, exposing a structural squeeze that is forcing vehicle manufacturers to rethink their entire supply chain posture.
The headline numbers from China's Passenger Car Association (CPCA) tell a stark story: the domestic auto industry generated RMB 51,893 billion (US$7.21 trillion) in revenue in the first half of 2026, a modest 1.8% gain, but profit collapsed at five times that pace. The resulting profit margin of 3.8% sits well below the 6.5% average logged by downstream consumer industries in the same period—and is less than half the 9% margin the sector recorded in 2014. At the vehicle assembly level, the squeeze is even more brutal: the China Association of Automobile Manufacturers (CAAM) Deputy Secretary-General Chen Shihua disclosed that average profit margins at the vehicle manufacturing stage fell to just 1.5% in H1 2026.
The divergence between assemblers and their upstream suppliers has rarely been this visible. Contemporary Amperex Technology (CATL) reported H1 2026 revenue of RMB 2,769.1 billion (US$384.6 billion), up 54.8% year-on-year, with net profit attributable to shareholders rising 41.98% to RMB 432.84 billion (US$60.1 billion). For investors tracking the electric vehicle value chain, the message is unambiguous: the economics of China's EV boom are accruing overwhelmingly to component suppliers, not to the brands on the showroom floor.
Costs Surging Faster Than Revenue Strips Per-Vehicle Profit
CPCA Secretary-General Cui Dongshu's chain-level analysis quantifies the damage precisely. Per-vehicle revenue across the industry chain reached RMB 344,000 in H1 2026, up 5% year-on-year. But per-vehicle costs and taxes consumed RMB 305,000 and RMB 25,000 respectively—rising 6% and 7.1%—leaving gross per-vehicle profit at just RMB 13,000, a 17.7% year-on-year decline.
The cost escalation is broad-based. Computer and communications electronics—a proxy for automotive chips—posted profit growth of 91% in H1 2026. Non-ferrous metals smelting surged 96%. Both categories sit squarely inside the bill of materials for every new-energy vehicle.
Executives have been candid. Xpeng Chairman He Xiaopeng acknowledged that "the vast majority of money earned goes back to partners running memory and lithium carbonate businesses." NIO founder Li Bin told China Automotive News that cost increases on the Onvo model exceeded RMB 10,000 per unit, translating to roughly RMB 15,000 in retail price impact. Li Auto absorbed more than RMB 14,000 in higher battery, memory, and chip costs per unit on the new-generation L6, yet held the sticker price at RMB 249,800—matching its predecessor—to defend market position.
Weakening Demand Removes the Safety Valve Automakers Needed
The demand side offers no relief. According to China Urban Passenger Car Association data, domestic narrow-definition passenger car retail sales totaled 8.701 million units in H1 2026, down 20.2% year-on-year. New-energy passenger vehicles—the segment that was supposed to drive volume recovery—fell 14% to 4.702 million units.
Policy headwinds are compounding the slowdown. EV purchase subsidies have been progressively phased out, and the announcement that plug-in hybrid and range-extended electric vehicles will be subject to vehicle and vessel tax starting 2027 has amplified consumer hesitation. Against annual sales targets set before the demand deterioration became apparent, most mainstream Chinese brands are tracking badly: only Zeekr is near 60% of its full-year target at the halfway mark; the rest cluster between 24% and 42% completion rates.
The combination of cost inflation and volume shortfall is structural, not cyclical. CAAM and CPCA data together confirm that total industry costs reached RMB 46,100 billion (US$6.4 trillion) in H1 2026, growing 2.8%—outpacing the 1.8% revenue expansion. Seres Group has guided for a net loss attributable to shareholders of RMB 1.5–1.8 billion (US$208–250 million) for the period. Great Wall Motor and Changan Automobile both project net profit declines exceeding 50% versus H1 2025.
Battery Self-Sufficiency Emerges as the Defining Strategic Bet
McKinsey's January 2026 research placed battery pack costs at 30%–40% of total battery-electric vehicle production cost—making it the single largest lever available to any automaker seeking to reclaim margin. Cui Dongshu's prescription is blunt: "Vehicle manufacturers universally do not make batteries, and therefore have no bargaining power."
His structural argument carries weight. CATL and BYD's captive battery unit Fudi Battery together held 57.28% of China's domestic power battery installation market in H1 2026, when total domestic power battery installations reached 335.6 GWh, up 12% year-on-year. That duopoly concentration gives both companies pricing authority that individual automakers cannot easily contest through procurement negotiations alone.
The response from vehicle manufacturers is accelerating. BYD, Great Wall Motor, Leapmotor, Chery, Geely, and GAC Group have all launched proprietary battery technology brands and developed in-house cell and pack manufacturing capability. Li Auto and Xiaomi Auto have since joined the cohort: Li Auto pursues self-designed packs with participation in cell development; Xiaomi Auto has reportedly completed a full in-house battery pack facility covering incoming cells, modules, and pack assembly, while sourcing cells externally.
Leapmotor offers the most advanced data point on what vertical integration can deliver: the company claims its self-developed, self-manufactured model gives it control over 65% of total vehicle cost and yields a 10% cost advantage versus peers relying on external supply. Cui frames the end state as "vehicle manufacturers as kings"—a scenario where automakers that master battery, electric drive, electronic control, and thermal management systems in-house can structurally improve unit economics regardless of commodity cycles.
Export Momentum Provides a Partial Offset—But Structural Risks Remain
One near-term margin lever sits outside the factory gate. CPCA data shows the export price of lithium batteries fell 12% year-on-year to RMB 104,800 (US$14,556) per unit in 2026, reducing the cost burden for export-oriented configurations. June 2026's relative profit improvement—the monthly rate reached 5.2% versus 3.7% in March–April—was partly attributed by Cui to a surge in premium-segment export volumes, suggesting overseas demand can temporarily offset domestic pricing pressure.
However, the structural arithmetic remains unfavorable. Anti-price-war initiatives have been in circulation for more than a year without producing measurable industry-level profit recovery. Until automakers can demonstrate that in-house battery programs translate from capital commitment into actual per-unit cost savings—a timeline that industry observers place no earlier than H2 2026 at best—the margin gap between China's vehicle assemblers and their upstream suppliers will continue to widen.
For investors, the actionable read is straightforward: the value in China's EV supply chain is migrating upstream, and the automakers best positioned to arrest that migration are those already deepest into vertical battery integration.
