A share price tends to move through four phases: moving sideways (stage 1), rising (stage 2), stalling near a high (stage 3) and falling (stage 4). Today American Superconductor Corporation is in stage 4. The phase helps read everything below.

Over the past 13 weeks it has done worse than the S&P 500, and it has been behind for 18 weeks running.

Over the last 10 years the share price moved +169% while the S&P 500 moved +246%, so it is behind the index over that whole period. It was last ahead over 13 weeks in the week of 2 July 2026. The chart above shows the 13-week comparison for every week.

This page treats a rise as over when the price closes below its 200-day average on two Fridays in a row.

American Superconductor Corporation pays no dividend. In the last 12 reported quarters it declared no dividend per share, so there is no payout history to chart and no yield to show. Companies like this usually keep their earnings in the business, so the cash-flow sections show where that cash goes.

American Superconductor is not in the Nasdaq 100, the S&P 500 or the Dow Jones 30, and is not on the US tech stocks list.

American Superconductor Corporation earned $3.0 M of net profit in the Sep 2026 quarter, −36.9% on the same quarter a year earlier. Full-year FY26 profit was $134 M. That is 3.2% of the quarter's revenue. The same quarter a year earlier earned $4.8 M. 3 of the last 12 reported quarters were loss-making.

Net profit is what is left after every cost, interest and tax. Earnings per share, dividends and book value all grow from it.

For the full year, FY26 profit was $134 M (+2,118.0% on the year before).

Why profit moved: revenue changed +42.8% on a year earlier and the margin moved −0.2 percentage points. Sales did the work, and the margin was about flat.

On average over the last four quarters, profit changed +1,239.8% and revenue +30.9%. Profit is growing faster than sales: fixed costs are spread over more sales, so each extra dollar of revenue adds more to profit.

American Superconductor Corporation reported $94.0 M of revenue in the Sep 2026 quarter, +42.8% on the same quarter a year earlier. That is the 12th quarter in a row with growth on the year before. Over 4 years it has grown 28.9% a year on average. The last full year, FY26, came in at $299 M.

Revenue is everything the company billed its customers in the period.

The last four reported quarters add to $349 M.

FY26 revenue was $299 M, +34.3% on the year before.

Recent pace: the last four quarters grew +30.9% on average, against 28.9% a year over the longer run, so this year is growing faster than its own long-run rate.

Is growth speeding up? Revenue over the last 12 months grew +31.1%, against +40.8% a year over the last 8 quarters (rolling over).

American Superconductor Corporation's operating margin was 4.3% in the Sep 2026 quarter, 0.2 percentage points lower than the same quarter a year ago. Its latest full-year margin is the highest it has ever reported. Across 5 years it has been between −30.1% and 5.9%. The latest quarter is within that range.

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

Why the margin moved: operating margin changed −0.2 percentage points on the year while gross margin changed −2.8 points. So the drop came mostly from the gross margin, which means input costs and prices charged.

As noted under valuation: when margins are at a record, every ratio built on profit looks better than usual, so a low multiple can mislead.

Over the last 2 years, 37% of American Superconductor Corporation's reported profit came in as cash from its operations, a gap worth watching. In FY26 it brought in $23.1 M of operating cash against $134 M of profit. After $4.9 M of spending on assets, $18.3 M was left over as free cash.

The profit and loss account shows what was earned. The cash-flow statement shows the cash that actually came in. Comparing operating cash flow with profit is one of the best checks that a profit is real.

Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year.

Why: the cash figure is clear, but the day counts behind it are not in our data, so we show it without guessing the reason.

What to look at next: the main use of cash is spending on assets. The next section checks what that spending is building.

American Superconductor Corporation does not report the customer, stock and supplier day counts a cash cycle needs, so this section looks at its spending on assets instead. It spent $8.2 M on assets over the last 3 years. Averaged over those years that is 0.9% of FY26 revenue a year.

Working capital is the cash tied up between paying suppliers and getting paid. Debtor days: how long customers take to pay. Inventory days: how long stock sits. The cash cycle: the whole loop, in days of sales.

Nothing is estimated in place of the missing day counts, so no cash-cycle chart is drawn.

Spending on assets: $8.2 M over the last 3 years.

In short: the cash is going into new capacity, not getting stuck in the daily cycle. The question is whether the new capacity earns.

American Superconductor Corporation's P/E is 8.0×, about the lowest it has ever been. Its usual P/E (the middle reading) is 84.0×, over 1 year of weekly prices. This compares the share price with the company’s own past. It does not say what the business is worth.

P/E is the share price divided by a year's profit per share: how many dollars the market pays for each dollar of yearly profit.

Keep one thing in mind: margins are the best this company has ever reported. A multiple that looks low against its own past can mislead when profit is at a record. If margins fall back, today's multiple is higher than it looks.

Why the multiple is where it is: over the past year earnings per share moved +1,806.2% while the price moved −39.8%. Earnings did better than the price, which pulled the multiple down within its own range.

In short: the multiple is low against its own past, so the earnings trend underneath matters more than the multiple.

American Superconductor Corporation's business trend cannot be read yet. There are fewer than eight usable quarters of growth figures, so there is not enough history to read the trend. This is based on 12 quarters of 2 measures, with some gaps.

Every business is somewhere on a path of getting better or worse, and this section names where. The last 12 quarters of growth in revenue, profit and earnings per share, plus the return the business earns on its capital, are read as lines. Getting worse: the lines are falling. Turning around: a low point has just formed and the last few quarters are rising from it. Getting better: the rise from the low has lasted. Growing steadily: steady growth with healthy returns. Slowing from a peak: still high, but slowing. When the lines disagree the result is mixed; too little history means no reading. CAGR (compound annual growth rate) is the steady yearly rate that would turn the starting value into the latest one. It is the fairest way to compare growth over different periods. If the 1-year figure is much bigger than the 10-year one, recent growth is running faster than the long-run trend. A dash means there is no figure for that period, or the starting year was a loss, where a growth rate means nothing.

Why it matters: with too little history, we say so rather than guess a direction.

One or more growth lines have an extreme jump caused by comparing with a near-zero or loss-making quarter. Those jumps are capped before reading and drawn at the edge of the chart, so one odd quarter does not decide the result.

There are fewer than eight usable quarters, so this page does not guess a direction from so little history.

Compound annual growth rate (%)

Compound annual growth rate over each period, %. Revenue, profit and EPS come from yearly figures; the stock price row is price growth over the same periods. A dash means no figure for that period, or the starting year was a loss.

American Superconductor Corporation earned a ROE of 24% in FY26. That is up from a low of −43% in FY23. Its return on capital used (ROIC) is 18.5 percentage points below its cost of capital, so growth here does not yet pay for the capital it uses.

Return on equity (ROE) is the profit the business earns on its shareholders’ money. We do not have the full capital split, so ROE is the longest history we can draw here.

It comes from a 44.7% net margin and 0.40× asset turnover (sales divided by assets).

Why the return is what it is (FY26): a 44.7% net margin × 0.40× asset turnover × 1.33× leverage (assets divided by equity) ≈ 23.8% on equity. The margin does most of the work; borrowing plays a small part, so this return is earned, not borrowed.

The key test, return on capital used minus the cost of capital: 3.6% − 22.1% = −18.5 percentage points. The 22.1% is an estimate of this company's own cost of capital. Read the sign and size of the gap, not the decimals. Negative: growth at these returns loses value until returns improve.

The 3.6% ROIC above is the latest reading, as reported. The yearly chart below shows FY26 at 6.5%, and the quarterly chart works out each 12-month window from the quarterly figures, so the readings differ by date, not by method.
