VinFast Auto Ltd.

Price story Before the numbers, the tape. A stock price moves through four repeating seasons: a flat base (stage 1), an advance (2), a top (3), a decline (4). Where the price sits in that cycle frames everything below.

VinFast Auto Ltd. trades at $3.0, building a base and 9 weeks into that stage. That is −13.2% against its own 200-day average. It sits at 7% of a 52-week range of $3 to $5. On relative strength it is currently behind the S&P 500 on a trailing-13-week view (10 weeks and counting).

Today the stock is building a base — week 9 of stage 1. At $3.0 it trades −13.2% versus its 200-day average and sits at 7% of its 52-week range ($3–$5).

Against the market, two honest reads. Cumulative: over the last 4.9 years the stock moved −69% while the S&P 500 moved +66% — behind the index over the full window. Recent form: on a trailing-13-week view the stock is currently behind (10 weeks and counting; last ahead the week of 2026-05-22) — the ribbon below is that same metric, week by week.

What would end the trend, mechanically: two Friday closes in a row below the 200-day line. That is the exit rule — no debates.

→ The trend is one thing; the bill is another. Are you paying up for it? Next: how the P/E reads against its own history.

Valuation P/E is the price of $1 of annual profit: how many dollars the market pays for each dollar the company earns in a year.

P/E does not price VinFast Auto Ltd. — earnings are negative, so there is no multiple to rank against its own history. The revenue and margin lines below are where a turn, when it comes, would show first. On sales the market values VinFast Auto Ltd. at 0.0× its FY25 revenue of $90,179 B.

With earnings negative, P/E does not price — there is no multiple to rank against its own history. The revenue and margin lines below are where the turn, when it comes, will show first.

Put together: the multiple is unremarkable against its own past, so the story rests on the earnings line underneath it, not the multiple.

→ Cheap or dear rides on the earnings. Are they actually growing? Next: the fundamental stage — where the business sits in its arc, and how growth has compounded.

Stage: No read Every business sits somewhere on a fundamental arc, and this page names the spot before anything else. The last twelve quarters of revenue, profit and EPS growth — plus the return the business earns on its capital — are read as curves: Deteriorating (the curves are falling), Turning around (a trough has just formed and the last few quarters lift off it), Improving (the climb off the trough is sustained), Consistent (steadily positive with healthy returns), Topping out (still high but decelerating from the peak). When the curves genuinely disagree the read is Mixed; too little history is No read. CAGR (compound annual growth rate) is the smooth yearly pace that turns the starting value into the latest one — the fairest way to compare growth across different time spans. Read the columns together: if the 1-year number towers over the 10-year, recent growth is running hotter than the long-run trend. A dash means that window is not held, or the base year was a loss (where a growth rate is not meaningful).

VinFast Auto Ltd. reads as no read on its fundamental arc. Under eight usable quarters on the growth trio — not enough history for an honest trajectory read. The read is built from 11 quarters across 1 curve, on partial evidence.

Why it matters: with too little history, an honest page says so instead of guessing a trajectory.

The latest quarter’s profit carries a one-off item larger than the operating base, so the profit curve is shown but does not vote in the stage call.

The return-on-capital curve is not shown — net worth is negative, so a return on capital is not a meaningful number in any basis. This is a distressed balance sheet, and the stage is read from the growth curves alone.

Fewer than eight usable quarters on the growth curves — this page will not guess a trajectory from a stub of history.

→ The stage names the trajectory. Next: the revenue line that produces it, quarter by quarter.

4-Factor Sector Score

No sector-relative score — VinFast Auto Ltd. is not among the largest members shown in this industry comparison for Auto Manufacturers.

The score is a rank WITHIN a peer set: every metric is scored by percentile against the other members. Without the peer set there is no score to state, so none is invented here.

Revenue Revenue is the top line: everything the company billed its customers in the period.

VinFast Auto Ltd. reported $24,259 B of revenue in the Mar 26 quarter, +45.9% year on year. That is the 12th straight quarter of year-on-year growth. Over 4 years it has compounded at 54.0% a year. The last full year, FY25, came in at $90,179 B. The last four reported quarters add to $98,380 B.

FY25 revenue came in at $90,179 B (+104.9% on the year), capping 4 years at 54.0% compound. The latest quarter (Mar 26) printed $24,259 B, +45.9% year on year — the 12th consecutive quarter of year-over-year growth.

Pace check: the last four quarters averaged +80.8% growth against the decade's 54.0% — the current year is running faster than its own long-run rate.

Acceleration check: trailing-twelve-month revenue grew +81.8% over the last 4 quarters against +74.1%/yr over the last 8 — accelerating.

→ Revenue grew — did margins hold as it scaled? Next: −98.9% this quarter (−25.1 pp YoY).

Operating margin Operating margin is what is left of every $100 of sales after running the business, before interest and tax. It is the cleanest read on pricing power and cost control.

VinFast Auto Ltd.'s operating margin is −98.9% in the Mar 26 quarter, −25.1 percentage points against the same quarter a year ago. Across 5 fiscal years the operating margin has ranged −319.9% to −82.2%. The current quarter sits inside that band.

VinFast Auto Ltd.'s operating margin is −98.9% in the Mar 26 quarter, −25.1 percentage points against the same quarter a year ago. Across 5 fiscal years the operating margin has ranged −319.9% to −82.2%. The current quarter sits inside that band.

The latest quarter's operating margin is −98.9%, −25.1 pp against the same quarter a year ago. Across 5 fiscal years the operating margin has ranged −319.9%–−82.2%.

🚨 Why the margin moved: operating margin went −25.1 pp year on year while gross margin went −38.3 pp — the loss came mostly from the gross line: input costs and pricing.

→ Margins slipped — did that reach the bottom line? Next: profit null in the latest quarter.

Net profit Net profit is what survives every cost, interest and tax — the number EPS, dividends and book value all grow from.

VinFast Auto Ltd. posted a net loss of $29,501 B in the Mar 26 quarter. That quarter carries a one-off item larger than its own revenue, so the year-on-year figure is an artefact rather than a trading result. The full FY25 year was a loss of $99,583 B. That loss is 121.6% of the quarter's revenue.

VinFast Auto Ltd. posted a net loss of $29,501 B in the Mar 26 quarter. That quarter carries a one-off item larger than its own revenue, so the year-on-year figure is an artefact rather than a trading result. The full FY25 year was a loss of $99,583 B. That loss is 121.6% of the quarter's revenue.

Mar 26 profit was $−29,501 B, null year on year. On the full year, FY25 printed $−99,583 B (null).

🚨 Read this profit with care: at $−29,501 B it is larger than the whole quarter's revenue of $24,259 B — no operating business earns more than it sells, so this is a one-off item (a debt-to-equity conversion, a tax write-back or an asset sale), not money the business earned. The underlying operations are running at −98.9% operating margin; the year-on-year jump and any P/E built on this number are artefacts of the one-off, not a real earnings turn.

→ Profit rose — but did the cash follow?

Cash flow — the router The P&L says what was earned; the cash-flow statement says what actually arrived. Operating cash flow (CFO) against profit is the cleanest lie detector in the accounts.

VinFast Auto Ltd.'s cash-flow history is too thin to judge how much reported profit converts into cash. In FY25 that was $−44,461 B of operating cash against $−99,583 B of profit. After $22,979 B of capital spending, $−67,441 B was left as free cash. Cash resolution here is annual, because quarterly cash statements are not published.

FY25: operating cash of $−44,461 B against reported profit of $−99,583 B, leaving free cash of $−67,441 B after $22,979 B of capital spending.

Cash-flow readings here are annual — that is the resolution our series carries, so this section moves once a year.

Router verdict: the visible cash user is investment — the next section checks what the spending is buying.

→ So follow the cash to where it goes. Next: $64,197 B of building over 3 years.

Where the cash goes Working capital is the cash tied up between paying suppliers and getting paid: debtor days (customers owe), inventory days (stock waits), and the cash conversion cycle (the whole loop, in days of sales).

VinFast Auto Ltd. does not report the debtor, inventory and payable day-counts a cash cycle is built from, so this section reads the investment side instead. Capital spending ran $64,197 B over the last 3 years. Averaged over those years that is 23.7% of FY25 revenue a year.

Working-capital day-counts are not in our numbers for this stock, so this section reads the investment side — where the cash is being put to work.

On the investment side: capital spending of $64,197 B over the last 3 fiscal years.

The synthesis: the cash is going into capacity, not disappearing into the cycle — the question becomes whether the new capacity earns.

→ Does all this activity actually earn its cost of capital? Next: ROE is null% and the ROIC − WACC spread is −153.2 pp.

Return on equity Return on equity (ROE) is the profit the business earns on its shareholders’ money. With the full capital-employed split not in our numbers, ROE is the cleanest long ladder we can draw here.

VinFast Auto Ltd. earns a ROE of 108% in FY25. That is up from a trough of 42% in FY21. Return on invested capital clears the cost of that capital by −153.2 percentage points, so growth here is not yet paying for the capital it uses. The wiring behind it is −110.4% net margin on 0.49× asset turns.

FY25 ROE is 108%, recovered from a FY21 trough of 42% — the full ladder below shows the fall and the climb, undoctored.

🚨 Why the return is what it is — the wiring (FY25): −110.4% net margin × 0.49× asset turns × −1.98× balance-sheet leverage ≈ 107.1% on equity. Margin does its share; leverage is modest — this is an earned return, not a borrowed one.

The capstone test — ROIC − WACC: −143.3% − 9.9% = a −153.2 pp spread. The 9.9% is an estimate of this company's own cost of capital — read the sign and the size of the spread, not the decimals. Negative — growth at these returns destroys value until the returns recover.

→ Returns like these — is the balance sheet borrowing to make them? Next: debt-to-equity is not in our numbers.

Dividend

VinFast Auto Ltd. pays no dividend. Across the last 12 reported quarters it has declared no dividend per share, so there is no payout history to chart and no yield to quote. Companies at this stage typically reinvest earnings rather than distribute them, which makes the cash-flow and reinvestment sections the place that cash shows up.

VinFast Auto Ltd. does not currently pay a dividend. Across the last 12 reported quarters the company has declared no dividend per share, so there is no payout history to chart and no yield to quote. Companies at this stage typically reinvest earnings instead of distributing them.

→ No payout to follow. The cash question becomes what the business does with what it earns instead.

Debt Debt-to-equity says how much of the business is funded by borrowings. Low is the safe corner; the trend matters as much as the level.

VinFast Auto Ltd.'s net worth is negative — it owes more than it owns — so a debt-to-equity ratio is not meaningful here. On the annual view that ratio went from −0.63 in FY21 to −1.23 in FY25. The returns elsewhere on this page are therefore earned rather than borrowed.

Mar 26: total debt of $122,428 B against shareholder equity of $−104,912 B — a debt-to-equity of −1.17. On the annual view, debt-to-equity went from −0.63 (FY21) to −1.23 (FY25). The returns on this page are earned, not borrowed.

→ Who owns this, and are they adding or leaving? Next: short interest is 4.7% of the float.

Ownership There is no quarter-by-quarter holder register to read here, so we read the crowd through short interest — the slice of tradable shares currently sold short, positioned for a fall.

4.7% of VinFast Auto Ltd.'s tradable float is currently sold short — some money is positioned against it. At typical trading volumes those positions would take about 5.1 days to buy back. There is no quarter-by-quarter holder register to read for this filer, so the crowd is read through short interest instead.

The latest reading: 4.7% of the float is sold short, and at typical trading volumes it would take about 5.1 days to buy those positions back. Some money is positioned against it. This is a single point-in-time reading — we do not yet hold its history, so we show no trend chart.

Why it sits there: who is doing the shorting, and why, does not travel with the number — the level is shown without inventing its story.

→ One last check: does the safety math agree? Next: the balance-sheet safety line.

Safety line The Z-score estimates how far a company sits from balance-sheet distress — above roughly 3 is safe, below roughly 1.8 is the danger zone. It was built for manufacturers, so it is not applied to banks and lenders.

VinFast Auto Ltd.: the Z-score reads −4.13. A Z-score above roughly 3 reads as safe and below roughly 1.8 as the distress zone, so this sits inside the distress zone. It is a distance-to-distress estimate from the balance sheet, not a forecast of failure.

🚨 Why it matters: a Z-score of −4.13 is inside the distress zone — the balance sheet is a real risk, not a detail.

The safety line in one sentence: the Z-score reads −4.13.
