CATL’s sharp selloff came down to a mismatch: the battery maker’s sales surged, but profit growth slowed and profit declined from the previous quarter. Investors also had reason to question whether product mix, tax changes and inventory write-downs would keep squeezing margins—and how much of those costs CATL could pass on to customers.

What happened to CATL shares and earnings?
On October 21, CATL’s Hong Kong-listed shares closed down 11.41% at HK$364.80. Reports put the Shenzhen-listed shares’ decline at more than 12%.

The selloff followed CATL’s third-quarter results:
- Revenue: RMB 165.221 billion, up 58.58% year over year.

- Net profit attributable to shareholders: RMB 21.246 billion, up 14.54% year over year but down 5.77% from the second quarter.

- Expectations: One reported market estimate put quarterly profit at RMB 26.03 billion, above the result. Separately, another report said analysts had expected profit growth of 41.2%, versus the actual 14.5%. These are different measures of expectations, but both point to a material shortfall.

The market reaction was not simply about whether CATL was growing. It was about how little of its much faster sales growth was showing up in profit.
Why profit growth lagged revenue
Lower-margin products weighed on the mix
CATL attributed pressure on unit profitability in part to changes in its product mix. Reporting points to a larger contribution from energy-storage shipments with lower margins, which can bring in revenue without generating as much profit per unit as higher-margin products.

Margins were under pressure
Several reports put CATL’s third-quarter gross margin at about 20.7%, down from 23.15% in the second quarter.

28 MarketWatch, citing Citi, reported a lower figure of 19.3%; the available reporting does not reconcile the difference.
26 The sources nevertheless point in the same direction: profitability weakened.
Tax changes added costs
Reports identified China’s battery consumption tax and reduced export tax rebates as additional pressures on CATL’s margins.

25 One report says the consumption tax was reinstated at 2% in September 2026, while another says a lower export rebate took effect during the third quarter.

These costs raise a key question: can CATL pass them on to customers, or will some of the burden remain with the company? Reporting said CATL was discussing how to share higher tax costs with customers, but the available evidence does not establish the outcome of those talks.

Inventory write-downs also contributed
CATL faced higher asset impairment losses. One report said impairment losses rose by RMB 1.2 billion quarter over quarter, largely because of inventory write-downs amid lithium carbonate price fluctuations.
12 Those write-downs added to the pressure on quarterly profit alongside operating and tax costs.
Competition adds to the concern
The earnings miss landed amid signs that some automakers want to diversify their battery supply. Forbes described this trend as “de-CATLization,” linking the move toward broader sourcing with investor concern about CATL’s position and negotiating leverage.

A separate report, citing Nikkei, said Xiaomi and Li Auto planned to source batteries from CALB and Sunwoda for new models and develop cells themselves.
19 Such plans do not by themselves establish a broad loss of CATL customers, but they underline why investors may be watching its customer relationships and pricing power more closely.
Broker reactions reinforced the focus on margins. Citi cut its price target, citing weaker-than-expected gross margins, higher expenses and greater impairment losses.
26 Reporting also described JPMorgan lowering its rating on CATL’s Hong Kong shares to Neutral.

What investors may watch next
A tax that affected only part of the third quarter could weigh on a larger share of the following quarter if it remains in place. That makes the cost-sharing question important: CATL’s ability to protect margins depends partly on whether customers absorb some of the added costs.

CATL’s management also expressed optimism about future battery demand. A report on the company’s outlook said it expected global demand for power and energy-storage batteries to grow by 20% to 30% the following year.
30 But demand growth alone does not answer the issue behind the selloff: whether stronger sales can translate into stronger profit when product mix, taxes, impairments and customer bargaining power are weighing on margins.
In short, October 21’s decline reflected a reset in expectations. CATL remained a fast-growing business by revenue, but its results raised doubts about how reliably that growth could convert into earnings.
