VinFast Auto (VFS) Stock Could Be Above Fair Value Despite Investor Investigation

Simply Wall St · 1d ago

VinFast Auto has put investors through a rough ride over the longer term, and that kind of history naturally raises a question about whether the current share price lines up with the sales the business is generating. With the stock now trading around US$3.21, the issue is less about short term swings and more about what that tag implies about the value of its revenue base.

  • The share price has fallen about 67.0% over 5 years, which puts the focus squarely on whether the valuation still matches what the company delivers in sales.
  • A recent investor investigation tied to rising operating losses and weaker gross profit margins points to pressure on how efficiently VinFast Auto can turn each dollar of revenue into sustainable value.
  • The analysts covering VinFast Auto have run their own numbers. See what analysts think VinFast Auto's shares could be worth.

For investors, the debate is whether VinFast Auto's current price is adequately supported by the level and quality of its sales today.

If you are weighing whether VinFast Auto's current tag of US$3.21 is fair for its sales profile, it can help to compare that context with 35 high quality undervalued stocks.

Is VinFast Auto Getting Expensive on Sales?

P/S is often a better yardstick for VinFast Auto because the group is still reporting free cash flow losses, so earnings-based measures do not tell you much about what investors are paying for each dollar of sales. On this metric, the stock trades on roughly 1.7x P/S, compared with an Auto industry average around 0.4x and a peer group nearer 1.2x.

That gap looks wide. The Fair Ratio model, which adjusts for VinFast Auto's margins, risk profile and size, points to a much lower multiple than the current 1.7x. The very large gap suggests the framework is heavily penalising the business for its cash burn and revenue quality rather than offering a precise target. Because the recent Pomerantz investigation highlights pressure on losses and gross margin, this richer P/S tag means you are paying a premium valuation for a company that is still working to stabilise its economics.
