VinFast Auto (NasdaqGS:VFS) is back in focus after outlining plans to sell two factories in Vietnam to cut about US$6.9b of debt, alongside rolling out upgraded electric SUVs and expanding global after-sales support.

The recent factory sale plan, upgraded VF 8 and VF 9 launches, and global service push arrive after a mixed run for investors. The share price is at US$3.57, with a 30 day share price return down 18.12%, a 90 day share price return up 9.85%, and a 3 year total shareholder return down 65.34%. This suggests sentiment has been volatile as the market weighs growth ambitions against the debt reduction story.

With the stock at US$3.57, trading well below the US$6.30 analyst price target and paired with efforts to cut roughly US$6.9b of debt, you have to ask: is there a real opportunity here, or is future growth already priced in?

Most Popular Narrative: 43.3% Undervalued

VinFast Auto’s most followed narrative puts fair value at $6.30 against the last close of $3.57, so the story focuses on how far the business can scale into that gap.

The rollout of dedicated VinFast charging infrastructure and ecosystem partnerships (GSM and V-GREEN) in Southeast Asia and beyond directly addresses the primary consumer barrier to EV adoption, supporting higher demand, increased deliveries, and ultimately greater revenue scale.

Transition to a more cost-efficient, next-generation vehicle platform and zonal E/E architecture is expected to materially lower bill of materials and production costs, improving gross and operating margins as scale and operational leverage increase.

Curious what kind of revenue trajectory and margin shift could justify that move from today’s price to the implied $6.30 fair value? The narrative focuses on substantial top line expansion, a leaner cost base, and a future profit multiple often associated with fast growing sectors, combined into one valuation story.

Result: Fair Value of $6.30 (UNDERVALUED)

However, you also need to keep an eye on heavy cash burn and continued reliance on Vingroup support, as well as limited brand recognition outside Vietnam and intense global EV competition.

Another View: Price Versus Sales Paints a Tougher Picture

Those analyst fair value stories are upbeat, but the P/S check is far less forgiving. At a P/S of 2.4x, VinFast trades well above the US Auto industry at 0.6x and the fair ratio of 0.1x, which points to meaningful valuation risk if sentiment cools.
