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 ON Semiconductor Corporation is in stage 1. 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 16 weeks running.

Over the last 10 years the share price moved +700% while the S&P 500 moved +261%, so it is ahead of the index over that whole period. It was last ahead over 13 weeks in the week of 17 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.

ON Semiconductor 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.

ON Semiconductor is on 2 of our US lists: S&P 500 companies and US tech stocks.

ON Semiconductor Corporation earned $227 M of net profit in the Jul 2026 quarter, +33.2% on the same quarter a year earlier. Full-year FY25 profit was $121 M. Over 4 years profit has grown −41.2% a year on average. That is 14.1% of the quarter's revenue. The same quarter a year earlier earned $170 M.

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

2 of the last 12 reported quarters were loss-making.

For the full year, FY25 profit was $121 M (−92.3% on the year before).

Why profit moved: revenue changed +9.2% on a year earlier and the margin moved +3.0 percentage points. Most of the change came from keeping more of each sale.

On average over the last four quarters, profit changed −18.5% and revenue −2.3%. Profit is growing slower than sales: rising costs are taking part of the growth.

ON Semiconductor Corporation reported $1.6 B of revenue in the Jul 2026 quarter, +9.2% on the same quarter a year earlier. That is the 2nd quarter in a row with growth on the year before. Over 4 years it has grown −2.9% a year on average. The last full year, FY25, came in at $6.0 B.

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

The last four reported quarters add to $6.2 B.

FY25 revenue was $6.0 B, −15.3% on the year before.

Recent pace: the last four quarters grew −2.3% on average, against −2.9% a year over the longer run, so this year is growing at about the same pace as its own long-run rate.

Is growth speeding up? Revenue over the last 12 months grew −3.1%, against −10.8% a year over the last 8 quarters (accelerating); profit over the last 12 months grew +35.3%, against −43.0% a year (accelerating).

ON Semiconductor Corporation's operating margin was 19.5% in the Jul 2026 quarter, 3.0 percentage points higher than the same quarter a year ago. Across 5 years it has been between 17.8% and 33.7%. 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 +3.0 percentage points on the year while gross margin changed +1.7 points. So the gain came mostly from costs below the gross margin, such as staff and overheads, measured against sales.

Over the last 3 years, 146% of ON Semiconductor Corporation's reported profit came in as cash from its operations, so the profit is backed by cash. In FY25 it brought in $1.8 B of operating cash against $121 M of profit. After $341 M of spending on assets, $1.4 B 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.

ON Semiconductor 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 $2.6 B on assets over the last 3 years. Averaged over those years that is 14.3% of FY25 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: $2.6 B 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.

ON Semiconductor Corporation's P/E is 41.5×, with too little history to compare. 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.

Why the multiple is where it is: over the past year earnings per share moved −92.0% while the price moved +49.0%. The price did better than earnings, which pushed the multiple up within its own range.

Where the price move came from: over 3 years the price moved +1.5% a year; about −32.1% a year came from earnings growth and about +33.6 percentage points from the multiple (the market paying more). The split is approximate (price return minus earnings growth). It shows how much of the move came from the market paying a different multiple.

In short: there is too little history to say whether the multiple is high or low for this company, so the earnings trend underneath matters more than the multiple.

ON Semiconductor Corporation's business is turning around. Profit growth has swung from −81.8% at its low to +35.3%, improving for 2 quarters in a row, with ROCE rising at 10.1%. This is based on 12 quarters of 4 measures.

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: a turn in growth is often where a bigger change starts. The lines say a turn is forming, so the question is whether the next quarters confirm it.

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.

ON Semiconductor Corporation earned a ROE of 2% in FY25. Its return on capital used (ROIC) is 0.6 percentage points below its cost of capital, so growth here does not yet pay for the capital it uses. It comes from a 2.0% net margin and 0.48× asset turnover (sales divided by assets).

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.

Why the return is what it is (FY25): a 2.0% net margin × 0.48× asset turnover × 1.63× leverage (assets divided by equity) ≈ 1.6% on equity. The margin does its share; borrowing is a big part of it.

The key test, return on capital used minus the cost of capital: 13.3% − 13.9% = −0.6 percentage points. The 13.9% 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 13.3% ROIC above is the latest reading, as reported. The yearly chart below shows FY25 at 11.3%, and the quarterly chart works out each 12-month window from the quarterly figures, so the readings differ by date, not by method.
