BYD's Overseas Sales Jump 91% as R&D Spending Outpaces Profit

BYD is leaning on international markets to offset a shrinking home base, and the numbers for the first nine months of 2026 make the shift plain. Overseas volumes climbed roughly 91% year on year between January and September, while domestic sales fell about 30%. Foreign markets accounted for around 43% of total deliveries in that window, up from roughly 21% a year earlier. All told, the automaker moved about 3.1316 million vehicles over the nine months.

The export surge comes against a backdrop of mounting trade barriers. Import duties on BYD vehicles run from 27% in the EU to 100% in the US, and the company is challenging its US designation in court. Stella Li, BYD's executive vice president, flagged geopolitics as the single biggest hurdle to the group's international build-out and named both the tariffs and the US listing among the obstacles in its path. How well BYD can work around those restrictions will go a long way toward determining whether overseas demand can keep compensating for weakness at home.

R&D Bill Tops Net Profit

The expansion is being funded by a hefty research budget. Executive vice president He Zhiqi said on 1 November that BYD spent 36.3 billion RMB on research and development in the first nine months of 2026 — more than the 22.3 billion RMB net profit it booked over the same period. Cumulative R&D outlays have now passed 280 billion RMB, he added.

Quarterly results, however, landed short of expectations. Net profit for the third quarter of 2026 came in at 10.02 billion yuan, against analyst forecasts of 11.4 billion to 12.95 billion yuan. Revenue of 221.5 billion yuan also disappointed, with higher dealer discounts on older models weighing on average selling prices, according to media reports. Hong Kong-listed shares slipped intraday on 30 October following the release.

October deliveries offered a brighter read. BYD sold about 490,000 new-energy vehicles, up 10.97% from a year earlier, though Reuters noted the pace slowed from September. Exports more than doubled in October, rising 102.8% to roughly 170,000 units, and overseas business helped offset soft domestic demand and fierce price competition. Even so, cumulative sales from January to October stood about 2.16% below the prior-year level, at around 3.6 million vehicles.

Solid-State Ambitions and a Cautious Timeline

Li Yunfei, the company's brand and PR chief, said yesterday according to Caixin that full-year sales should come in slightly above last year's level, with overseas markets expected to grow faster. The scale of the business is already considerable: BYD sold 4.6 million vehicles across 120 countries and regions last year, generating revenue of $111 billion, according to Time. The company is chasing the top spot among global automakers, a goal that increasingly rests on its international business.

On solid-state batteries, Stella Li struck an ambitious note, saying BYD will be the first company to put the technology into series production. She paired that claim with a caveat — the technology still needs to mature, and the industry may have to push back its targeted 2030 timeline. Chips tell a similar story of self-development balanced with outside partners: Li said in-house semiconductors will never cover all BYD vehicles, and Nvidia remains a partner. Whether that mix of homegrown technology and external alliances can deliver durable growth in the face of steep political hurdles is the question that now hangs over the stock.
