Management Commentary

Madam Thuy Le, Chairwoman of VinFast, said: “I am pleased with the progress we’ve made over the past year. Despite Q1 typically being our slowest quarter, deliveries for the first quarter of 2025 exceeded our total deliveries for the first half of last year—an encouraging start to 2025 amid ongoing global uncertainties. We are beginning to see improved operating leverage as volume growth and a streamlined footprint translate into a more efficient cost structure. Looking ahead, our next-generation EV platform and E/E architecture is intended to further BOM cost optimization, enhancing product quality, performance, and affordability across our lineup.”

Ms. Lan Anh Nguyen, Chief Financial Officer of VinFast, added: “Our business is at an inflection point, with economies of scale beginning to drive stronger operating leverage. We have made progress in reducing both costs of vehicles sold (COGS) and operating expenses, and continue to streamline our footprint while identifying further cost-saving opportunities.”

Financial Results for the First Quarter of 2025

Revenues

Revenue growth from the first quarter of 2025 was driven by an increase in EVs sale volumes due to growth in the Vietnam market and contributions from new overseas markets. The decrease compared to the fourth quarter of 2024 was attributed to a decrease in EVs sales volumes due to seasonality and the Lunar New Year in Vietnam.

Business Outlook

VinFast’s target markets are Vietnam, Indonesia, the Philippines, India, North America and Europe, and it is regularly evaluating opportunities to enter new countries and regions in Europe, Asia, the Middle East and Africa. VinFast’s aim is to grow its global footprint in areas where it may identify high potential for EVs. VinFast may establish or enlarge its presence in existing and new markets through different distribution models, with dealerships being the predominant approach in the recent past. To ensure that VinFast continues to have sufficient production capacity to support its current and future operations, it will, from time to time, endeavor to add manufacturing, assembly and distribution capacity across its markets through the expansion of existing infrastructure and new brownfield and greenfield projects. While VinFast remains focused on the mini- through E-segments of the electric SUV market, it is also evaluating the full spectrum of vehicle types for future product development. VinFast continuously monitors its global expansion strategy and has the ability to accelerate, moderate or otherwise deviate from its existing distribution, manufacturing, assembly, marketing and other plans for any market at any time.

VinFast’s funding sources for its capital requirements to implement its growth strategy may include loans and grants from its major shareholders and affiliates, the public and private debt and equity capital markets, existing and new third-party loans and borrowings and cash from operations. VinFast is prepared to opportunistically access the debt and equity capital markets, subject to market conditions. VinFast also seeks to capture available tax and other incentives and subsidies to reduce its costs of investment and operations.

Conference Call

The Company’s management will host its first quarter of 2025 earnings conference call at 8:00 AM U.S. Eastern Time on June 09, 2025.
