Management Commentary

Madame Thuy Le, Chairwoman of VinFast, said: “VinFast delivered another strong quarter with robust year-on-year growth, underscoring the continued momentum behind our growth and the global shift to electric mobility, also keeping us on track to at least double our deliveries in 2025. While evolving macro conditions and shifting regulatory landscapes are creating new challenges for the EV industry, our long-term vision to become a global leader in electric mobility remains the same and we are committed to delivering high-quality, accessible EVs that meet the needs of customers around the world. We are maintaining our 2025 delivery guidance, and our go-to-market strategy is being refined to stay agile in the face of evolving macro and regulatory developments.”

Ms. Lan Anh Nguyen, Chief Financial Officer of VinFast, added: “We see tremendous opportunity in our core Asian markets, and stepping up promotions is a necessary investment to build long-term brand awareness. Our path to profitability is driven by scaling volumes while being disciplined on costs — that hasn’t changed. Our business is now at an inflection point where we expect economies of scale to drive greater operating leverage going forward.”

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, grants, and transactions with 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.
