Insights

EV sector analyst

Record Vietnam deliveries signal scale, but figures are preliminary.

VinFast reports 13,914 domestic EV deliveries in September 2025 and 103,884 in the first nine months of 2025. Model mix skews to entry and mid segments: VF 5 led September with 3,847, while year-to-date leaders are VF 3 (31,386) and VF 5 (30,956).

The company states results are preliminary and deliveries are only one metric; revenue recognition can differ due to average selling price and cost components. This tempers direct financial read-through from unit counts.

Operationally, the disclosed sales mix highlights breadth across models including VF 6 (14,425 YTD) and newer nameplates like Herio Green (8,604) and VF 7 (5,877). Actual financial impact will depend on pricing and costs reported in subsequent financial statements.
