• Right now, VinFast Auto scores 3 out of 6 on Simply Wall St's valuation checks. Next up is a look at how different valuation methods treat the stock and, later in the article, a way to get an even richer view of what that score really means.

Approach 1: VinFast Auto Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a company could be worth by projecting its future cash flows and discounting them back to today’s value. It tries to answer what those future streams of cash are worth in today’s terms.

For VinFast Auto, the model used is a 2 Stage Free Cash Flow to Equity approach, based on cash flow projections in ₫. The latest twelve month free cash flow is a loss of ₫80.4 million. Projections supplied include an estimated free cash flow of ₫23.9 million in 2030, with intermediate years moving from losses to positive figures. Beyond the analyst supplied period, Simply Wall St extrapolates further cash flows to complete the 10 year path.

Putting all of those projected cash flows together, discounting them back, and allowing for the second stage assumptions, the model arrives at an estimated intrinsic value of US$3.80 per share. Compared with the recent share price of US$2.95, the DCF output suggests the shares are about 22.4% undervalued based on these inputs and assumptions.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests VinFast Auto is undervalued by 22.4%. Track this in your watchlist or portfolio, or discover 49 more high quality undervalued stocks.

Approach 2: VinFast Auto Price vs Sales

For companies where earnings are weak or volatile, the P/S ratio is often more useful than P/E because it compares the share price to revenue, which is usually more stable than profits. Investors typically look for a P/S multiple that matches their expectations for future growth and risk, with higher growth or perceived quality often justifying a higher ratio and higher risk usually pointing to a lower one.

VinFast Auto currently trades on a P/S of 2.01x. That sits below the peer average of 2.28x, but above the broader Auto industry average of 0.64x. Simply Wall St also provides a proprietary Fair Ratio of 0.10x, which reflects what the P/S multiple might be given factors such as the company’s growth profile, industry, profit margins, market cap and risk characteristics.

This Fair Ratio aims to be more tailored than a straight comparison with peers or industry averages because it adjusts for company specific traits rather than assuming all Auto stocks deserve similar multiples. Setting the current 2.01x P/S against the Fair Ratio of 0.10x suggests the shares trade above that modelled level.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your VinFast Auto Narrative

Earlier the article mentioned that there is an even better way to understand valuation, so this is where Narratives come in as a simple way for you to attach a clear story about VinFast Auto to a set of forecasts for revenue, earnings, margins and ultimately a fair value estimate.

A Narrative is your own version of the VinFast Auto story, where you decide what you believe about factors such as EV adoption, profitability and capital needs, then connect those views to numbers like future earnings and an assumed fair value rather than looking at ratios in isolation.

On Simply Wall St, Narratives sit inside the Community page and are designed to be accessible, so you can compare your view with how millions of other investors frame the same company and see how different stories translate into different valuation outcomes.

For VinFast Auto, one investor might lean toward a more optimistic Narrative that lines up with a fair value around US$7.95 per share, while another might prefer a cautious Narrative closer to US$5.50 per share. By comparing those fair values to the current market price, each investor can decide whether the stock looks interesting based on their own assumptions.

These Narratives update automatically when new news, guidance or earnings data is added to the platform, so your story, forecasts and fair value stay linked to the latest information without you having to rebuild the whole model each time something changes.
