VinFast Announces Delivery Results for the SecondQuarter of 2024 and Business Updates

12,058 vehicles delivered in Q2 2024, an increaseof 24% quarter-over-quarter, and a 26% increase year-over-year

Singapore, July 12, 2024 – VinFast Auto Ltd. (“VinFast” or the “Company”), a pure-play electric vehicle (“EV”) manufacturer with the mission of making EVs accessible to everyone, today announced its delivery results for the second quarter of 2024.

For the second quarter of 2024, VinFast delivered 12,058 vehicles, representing an increase of 24% quarter-over-quarter and an increase of 26% compared to the same period of last year. Through 1H2024, VinFast has delivered 21,747 vehicles, up by 92% compared to 1H2023.

While the second quarter delivery results were encouraging, ongoing economic headwinds and uncertainties in different macro-economies and global EV landscape necessitate a more prudent outlook for the rest of the year. The Company now anticipates delivering approximately 80,000 electric vehicles in 2024, compared to 34,855 vehicles delivered in 2023, or 2.3x year-over-year growth.

In addition, VinFast has made the strategic decision to adjust the timeline for the launch of its North Carolina manufacturing facility, which is now expected to begin production in 2028. This decision will allow the Company to optimize its capital allocation and manage its short-term spending more effectively, focusing more resources on supporting near-term growth targets and strengthening existing operations.

Madam Thuy Le, Chairwoman of the Board of Directors, stated, “We have adopted a more prudent outlook that is carefully calibrated to near-term headwinds, taking intofull consideration the realities of market volatility and potential challenges. Our robust long-term strategy and proven executioncapabilities position us well to meet the evolving needs of the dynamic global EV market.”

The Company also announced that it will release its 2Q24 financial results before the market opens on August 15^th^, 2024. On the same day, VinFast’s management will host a live webcast to discuss the Company’s business performance and strategy. Details for the call are below:
