BYD's Record October Cuts Both Ways: 300,000 EVs for the First Time, but a Profit Miss and a Shrinking Home Market

BYD's stock picked up 2.6% in pre-market trading after the Chinese automaker reported its October delivery figures, with the export engine doing most of the heavy lifting. Yet the same numbers that lifted sentiment also laid bare an awkward split: battery-electric vehicles are racing ahead, plug-in hybrids are sliding backwards, and the domestic market is contracting.

The headline figure was hard to miss. BYD sold 305,743 pure electric passenger cars last month, up 37.38% year on year — the third consecutive monthly record and the first time the company has cleared the 300,000 mark for battery-electric models in a single month. Total sales of vehicles with alternative drivetrains reached 490,168, of which the EV tally formed the bulk.

Plug-in hybrids, by contrast, fell to 177,382 units, a decline of 17.23% from a year earlier and also down on September. Pure EVs therefore accounted for 63.28% of passenger car sales — a mix shift that flatters the overall number but tells a more complicated story underneath.

Exports double, but momentum cools month on month

Overseas shipments came in at 170,194 vehicles with electric or plug-in hybrid powertrains, a jump of 102.84% compared with October 2025. Against September, however, exports slipped 5.81% — the second consecutive monthly decline. Bloomberg framed the export performance as relief for the share price, while Reuters described it as a counterweight to sluggish domestic demand and fierce price competition.

That distinction matters. The year-on-year surge and the month-on-month softening are two different signals, and investors who read only the former risk mistaking a strong annual comparison for accelerating momentum. In China itself, BYD sold 319,974 vehicles in October, down 10.6% year on year. Robust exports, in other words, coincided with a weaker home market rather than offsetting it evenly across regions.

The profit test is where the story gets harder

Volume alone has never been the deciding metric, and the third-quarter results published on Thursday made that plain. Net profit for Q3 2026 came in at RMB 10 billion on an unaudited basis, against broker estimates compiled by Reuters that ranged from RMB 11.4 billion to RMB 12.95 billion. The result fell short of the entire forecast range.

The underlying operating trend was stronger than that miss suggests. Revenue rose 13.6% to RMB 221.5 billion in the third quarter, and net profit climbed 28% year on year. The gap between growth and expectations is the crux: BYD is expanding, but not at the pace the market had priced in.

Balance-sheet charges add another layer. On Friday the company reported credit and asset impairments of RMB 3,654,330 thousand for January through September 2026, of which RMB 2,794,209 thousand related to inventory write-downs. Those figures document a hit already taken — neither proof of further deterioration nor evidence of imminent relief.

A cumulative deficit that one record month cannot erase

For all October's strength, the year-to-date picture remains behind last year. Sales from January to October totalled 3,621,744 vehicles, compared with 3,701,852 in the same period a year earlier — a shortfall of 2.16%. The EV surge has not yet compensated for weakness elsewhere.

Media reports put BYD's full-year target at 5.0 to 5.5 million vehicles, which means a strong year-end push would need to deliver more than further records in a single drivetrain category. BYD notes that its monthly sales figures are unaudited and subject to revision.

The investment question, then, is not simply growth versus crisis. It is whether the growth holds up. Export demand offers a genuine reason for optimism; the earnings miss attaches a clear condition to it. Further monthly delivery reports will show whether overseas demand retains its cushioning effect, but only subsequent financial results can supply the economic proof.
