CATL Rebounds 3.2% as Washington Opening and Buyback Collide With Margin Doubts

CATL shares rose 3.2% to 306.77 CNY after hitting a 52-week low of 295.50 CNY, as US pickup battery news and a buyback offset domestic share worries.

Shares of CATL climbed 3.2% to 306.77 CNY on Tuesday, snapping a bruising stretch that had just pushed the world's largest battery maker to a fresh 52-week low of 295.50 CNY a day earlier. Two separate forces are pulling the stock in opposite directions: a possible breakthrough in the United States, and a home market where customers are steadily spreading their orders around.

A Tall Battery Aimed at American Pickups

The immediate spark came from reports in the Financial Times that CATL has developed a dedicated high-cell design—internally described as a "tall battery"—built specifically for US pick-up trucks. Chief Technology Officer Zhu Lingbo confirmed the development to the newspaper, a disclosure that first surfaced on 9 September.

Traders are pairing that product news with speculation that CATL representatives could join a Chinese government delegation at bilateral talks on 24 September. Hopes for trade relief, or at least concrete steps toward entering the US market, have given the stock a rare tailwind after weeks of gloom.

Management Pushes Back on the Skeptics

The rebound follows a sharp deterioration in sentiment. Mid-month, CATL's A-shares fell roughly 10% across two consecutive trading sessions, with market watchers pointing to rumors of September production cuts and worries about thinning per-unit profit in the third quarter. Over a 30-day window, the decline reached 23%, and Monday's close of 297.05 CNY in Shenzhen underscored how much ground had been lost.

Technical chief Lin Jiubiao used a Bloomberg report to counter the pessimism, insisting the company's full-year targets remain untouched. China's consumption tax on lithium-ion batteries, in force for just over three weeks, has had only a limited effect on domestic orders, he said, with minor fluctuations offset by fresh demand. The overall business outlook for 2026, according to Lin, is unchanged.

The Per-Unit Profit Question

Whether that reassurance holds depends heavily on one metric: net profit per battery unit in the current quarter. The new levy has forced the entire value chain to recalculate, and while CATL's scale gives it unusual room to absorb costs, it is unclear how much of the tax burden can be passed on to automakers. If the company had to concede on pricing to protect volumes, unit margins will compress. If efficiency gains offset the charge, the resilience of the model would be emphatically confirmed.

Buyback and New Markets Provide a Floor

Management has put money behind its own conviction. On 11 September, CATL repurchased 604,293 A-shares through the Shenzhen exchange's central bidding process at prices between 330.15 and 331.61 yuan apiece—a total outlay of 199,978,827.46 yuan before ancillary costs. The move signals that the leadership views its own stock as undervalued at the depressed level.

Beyond the core auto business, CATL is widening its footprint. An 18 August strategic partnership with the VNET Group will build a three-tier ecosystem linking computing infrastructure with zero-emission energy technologies, opening a growth avenue outside passenger vehicles. On the international front, the company signed a cooperation agreement with Egypt's BME covering battery-pack technology licensing, production equipment supply and training. That plant is initially planned for one gigawatt-hour of annual capacity, with a path to five gigawatt-hours.

Closer to home, CATL is shoring up its raw-material base. Its subsidiary Yichun Contemporary New Energy Mining has resumed the environmental impact assessment process for the Jianxiawo lithium mine project—a step seen as important for securing medium-term self-sufficiency in lithium.

Rivals Are Quietly Taking Pieces of the Pie

The cautious case rests on harder operational ground. Chinese automakers are actively reducing their reliance on a single dominant supplier. Li Auto has announced it will roll out its own battery solutions across its entire model line-up. Official documents from the Ministry of Industry and Information Technology show the new Li i6 SUV will use cells from rival CALB. Xpeng elevated CALB to its largest battery supplier, while Huawei-backed Aito dropped its exclusive arrangement with CATL and added both CALB and Gotion High-tech to its network.

Xiaomi now works with four suppliers—FinDreams, Sunwoda, CALB and CATL—yet its new Sky Nomad line uses only Sunwoda and CALB cells, leaving CATL on the sidelines. When established customers spread their orders, growth in the domestic market comes under pressure.

The Line in the Sand

For investors, the 52-week low at 295.50 CNY has become the decisive support level. If it holds and management's assurances about stable domestic orders prove accurate, the case for a recovery stays alive. A sustained break below it would entrench fears of shrinking unit margins and lost market share, risking a further slide. The next real catalyst for a fundamental re-rating will be the third-quarter earnings report—the moment when it becomes clear whether per-unit profit withstood the cost squeeze.
