Upstream Wins, Downstream Bleeds: China's EV Supply Chain Splits

A Tale of Two Balance Sheets

Recent earnings disclosures from Chinese electric-vehicle companies reveal a stark divergence: the firms mining lithium, refining battery precursors, and fabricating cells are posting healthy margins, while the automakers assembling those components into finished cars report mounting losses. BAIC, Seres, and GAC - three established players with meaningful EV portfolios - have each flagged deteriorating profitability in preliminary guidance, even as upstream suppliers signal continued strength.

The split is not subtle. Battery-materials processors that struggled through 2023's lithium-price collapse have rebuilt pricing power as demand stabilizes and new capacity comes online more slowly than anticipated. Automakers, by contrast, remain locked in a protracted discount cycle that shows no sign of easing. At DailyTechWire, we've tracked similar upstream-downstream disconnects in semiconductor supply chains and smartphone ecosystems, but the speed and scale of this reversal in China's EV sector stands out.

Why Input Costs Are Rising Again

Lithium carbonate and hydroxide prices bottomed in late 2023, then began a steady climb through the first half of 2024 and into 2025. Spot quotations for battery-grade lithium carbonate in China climbed above 100,000 yuan per metric ton by mid-2025, roughly double the trough, according to data from Shanghai Metals Market. That recovery has flowed straight through to the profit-and-loss statements of mining companies and chemical processors.

Meanwhile, nickel and cobalt - key ingredients in higher-energy-density cells - have seen less dramatic swings but remain elevated relative to the lows of 2020 and 2021. Automakers locked into shorter-term supply agreements find themselves renegotiating at less favorable terms, while the largest battery producers pass along cost increases with minimal friction.

The structural advantage lies in concentration. A handful of vertically integrated materials groups control significant portions of refining and precursor capacity, giving them leverage that fragmented vehicle assemblers lack. CATL, for instance, has secured long-term offtake deals and equity stakes in upstream mines, insulating its own cell business while smaller automakers scramble for spot supply.

The Automaker Squeeze

Chinese EV manufacturers entered 2025 hoping that a post-subsidy shakeout would restore rational pricing. Instead, competition intensified. New models from BYD, Geely, and a wave of startup brands flooded showrooms, and the average transaction price for battery-electric sedans and SUVs continued to drift downward.

BAIC's electric-vehicle unit, which had posted modest quarterly profits in 2023, swung to a loss in the first half of 2025. Seres - known for its collaboration with Huawei on the AITO brand - likewise flagged weaker results, citing both volume pressure and unfavorable input costs. GAC, which operates a joint venture with Honda and has launched its own Aion EV line, reported that electric-vehicle operations dragged group margins below breakeven in certain quarters.

None of these companies lack scale or technical capability. The issue is margin defense. When a 10 percent reduction in vehicle price meets a 15 percent increase in battery-pack cost, the math becomes unforgiving. Automakers have responded by paring optional features, reducing battery capacity on entry trims, and leaning harder on software subscriptions, but these measures buy time rather than solve the underlying imbalance.

Where the Profits Pooled

Upstream, the picture is brighter. Lithium miners that survived the 2023 downturn emerged leaner and more disciplined. CATL, the world's largest battery-cell producer, obtained regulatory clearance to restart a flagship lithium mine, ensuring feedstock security and further vertical integration. Smaller precursor and cathode-materials suppliers have consolidated, and the survivors enjoy better utilization rates and pricing discipline.

This is not a story of monopoly rent-seeking. Demand for batteries remains robust, and the supply base has rationalized after a period of overbuilding. What has changed is bargaining power. A decade ago, automakers dictated terms to a fragmented component base. Today, a concentrated upstream extracts value from a fragmented downstream.

The shift mirrors dynamics in other technology hardware markets. Semiconductor fabs and advanced-packaging houses command premium economics relative to device assemblers. Display-panel makers oscillate between glut and shortage, but the brands that buy those panels operate on thinner margins. In each case, capital intensity and technical complexity create moats that assembly scale cannot easily replicate.

Policy and Market Structure

Chinese industrial policy has long favored upstream investment. State-backed funds financed lithium-mining ventures in Australia, Chile, and Africa, while local governments offered subsidies for battery-cell gigafactories. The result is a supply chain that is both globally dominant and domestically competitive, but the benefits accrue unevenly.

Automakers, by contrast, face a more fragmented support landscape. Municipal governments offer site incentives and tax breaks, but these are tied to employment and local content rather than profitability. The central government's NEV subsidy program wound down in 2022, and subsequent stimulus measures have targeted consumer rebates rather than manufacturer margins.

Export markets offer a potential release valve. Chinese EV brands have expanded aggressively into Southeast Asia, the Middle East, and Europe, seeking higher transaction prices and less saturated competition. Yet tariff headwinds - most notably in North America and the European Union - limit the scale of that opportunity. BYD's partnership with a Japanese luxury dealer and exploratory manufacturing in Mexico signal ambition, but neither moves the needle on domestic overcapacity in the near term.

What Comes Next

The current profit distribution is unlikely to persist indefinitely. History suggests that automakers will eventually secure better input terms through vertical integration, long-term contracts, or supplier consolidation. BYD's in-house battery production and Tesla's agreements with lithium producers point the way. Smaller players may merge or exit, reducing the number of entities competing for the same input slate.

In the meantime, the divergence offers a lens on China's broader industrial evolution. The country has moved beyond assembly-led growth; value now resides in technology, materials science, and capital-intensive processing. Automakers that treat batteries as commodities will struggle. Those that invest upstream or forge genuine partnerships with materials suppliers will find more defensible economics.

For investors and competitors watching from Seoul, Tokyo, Detroit, and Stuttgart, the lesson is clear: controlling the supply chain's chokepoints matters more than controlling the brand on the hood. China's EV sector is learning that lesson in real time, and the rest of the world is taking notes.
