BYD's Record Export Month and Covestro Deal Highlight a Two-Pronged Growth Strategy

BYD sets monthly overseas sales record of 175,349 units in June 2026, aims to overtake Toyota in five years, and partners with Covestro for advanced EV materials.

BYD has just delivered its strongest-ever month of overseas sales, while simultaneously deepening ties with a German chemical giant to gain tighter control over the materials that go into its vehicles. The two developments, announced in the same week, paint a picture of a company that is not only pushing volume but also re-engineering its supply chain from the ground up.

The Chinese electric-vehicle maker shipped 175,349 units abroad in June 2026, nearly double the figure from a year earlier and a new monthly record. That overseas surge, alongside 403,472 total vehicles sold worldwide, helps explain why Stella Li, head of BYD's international business, felt emboldened to declare on July 15 that the company intends to unseat Toyota as the world's largest automaker within five years — and to do it entirely without the US passenger-car market, which remains off-limits due to tariffs and software restrictions.

BYD's second-quarter numbers reinforce that ambition. The group delivered 557,090 battery-electric vehicles in the period, enough to pull ahead of Tesla in pure-EV sales for the quarter. For the full year 2025, BYD had already reported 2.26 million EVs sold against Tesla's roughly 1.6 million.

The export boom is not just a BYD phenomenon. China's total vehicle exports crossed the million-unit mark for the first time in a single month in June, reaching 1.037 million — a 75.1 percent year-on-year jump. New-energy vehicles drove the charge: NEV exports hit 523,000 units, up 160 percent from the prior year.

Against that backdrop, BYD has signed a memorandum of understanding with Covestro, the German specialty chemicals group, to co-develop advanced materials for electric vehicles, battery systems, energy storage, and public transport. The agreement goes well beyond a standard supplier contract. It envisions joint innovation programs, shared technology development, and possible strategic investments. Covestro brings deep expertise in polycarbonate and polyurethane materials — key ingredients for lighting, interior and exterior panels, and electronics in connected mobility applications — as well as lightweight high-performance materials that improve safety, thermal management, and cost efficiency.

Sustainability is a formal pillar of the deal. The two companies plan to work on low-carbon and circular material solutions, with Covestro's CQ portfolio — which contains at least 25 percent alternative raw materials — taking a central role. If the new materials scale into mass production, the implications could ripple across BYD's cost structure and its ability to tailor products for export markets with widely varying climate and regulatory demands.

Yet the partnership remains in its early stages. It will likely require upfront research spending and capital commitments before any benefits materialize. BYD's profit margins are already under pressure from a brutal domestic price war, and additional collaboration costs could weigh on earnings in the near term.

The stock market has taken note of both the operational momentum and the strategic repositioning, but the share price still reflects the deep decline of the past year. Hong Kong-listed BYD shares closed recently at €10.00, up 10.50 percent over the past month. The recovery began from a 52-week low of €8.03 on June 30, 2026, meaning the stock has clawed back about 24.5 percent since that trough. From the 52-week high of €14.80 set in July 2025, however, the shares remain 32.43 percent off. Over the trailing twelve months, the loss stands at 26.85 percent.

For investors, the Covestro tie-up provides a fresh narrative alongside the monthly delivery numbers and the overseas expansion story that have dominated recent trading. Whether the material innovations translate into tangible product advantages — and whether the partnership can help BYD close the gap with its 52-week high — will take several quarters to judge, as the first joint developments move from the lab into series production.
