Harmonic share price today

Harmonic Inc.'s share price was $10.21 at the close on 4 November 2026. That is 11.9% below its average price over the last 200 trading days. In the last 52 weeks it traded between $9 and $15, and at that close it sat 21% of the way up from that low.

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). 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 12 weeks running.

Over the last 1 year the share price moved +11% while the S&P 500 moved +23%, so it is behind the index over that whole period. It was last ahead over 13 weeks in the week of 14 August 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.

Harmonic Inc. 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.

Harmonic is on one of our US lists: US tech stocks.

Harmonic Inc. posted a net loss of $2.3 M in the Jul 2026 quarter. The full FY25 year was a loss of $43.3 M. That loss is 1.7% of the quarter's revenue. The same quarter a year earlier lost $8.1 M.

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, FY25 profit was −$43.3 M (−210.4% on the year before).

Harmonic Inc. reported $133 M of revenue in the Jul 2026 quarter. Over 4 years it has grown −8.2% a year on average. The last full year, FY25, came in at $361 M.

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

The quarterly figures for FY23, FY25 do not add up to the full-year total on file, so those quarters are left out of the charts and sums.

FY25 revenue was $361 M, −26.2% on the year before.

Harmonic Inc.'s operating margin was 18.0% in the Jul 2026 quarter. Across 5 years it has been between 3.8% and 18.1%. 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 +23.3 percentage points on the year while gross margin changed +0.7 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, 49% of Harmonic Inc.'s reported profit came in as cash from its operations, a gap worth watching. In FY25 it brought in $108 M of operating cash against −$43.3 M of profit. After $11.1 M of spending on assets, $96.9 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.

Harmonic Inc. 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 $28.7 M on assets over the last 3 years. Averaged over those years that is 2.7% 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: $28.7 M over the last 3 years.

In short: most of the cash goes on covering the loss, not on new assets; spending on assets is small next to it.

Harmonic Inc.'s P/E is 44.9×, 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 −214.4% while the price moved +2.0%. The price did better than earnings, which pushed the multiple up within its own range.

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.

Harmonic Inc.'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 4 quarters of 1 measure, 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.

The return figures here are yearly, not quarterly. They show level and direction only; they can support the growth lines but never decide the reading alone.

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.

Harmonic Inc. earned a ROE of −11% in FY25. Its return on capital used (ROIC) is 6.4 percentage points above its cost of capital, so growth here adds value, not just size. It comes from a −12.0% net margin and 0.50× 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 −12.0% net margin × 0.50× asset turnover × 1.87× leverage (assets divided by equity) ≈ −11.2% 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: 17.6% − 11.2% = +6.4 percentage points. The 11.2% is an estimate of this company's own cost of capital. Read the sign and size of the gap, not the decimals. A gap this wide means each dollar put back into the business creates more than a dollar of value.

The 17.6% ROIC above is the latest reading, as reported. The yearly chart below shows FY25 at 0.5%, and the quarterly chart works out each 12-month window from the quarterly figures, so the readings differ by date, not by method.

Harmonic Inc. has total debt of $130 M against shareholder equity of $360 M as of Jul 2026, so its debt is 0.36× its equity. Year by year, that ratio went from 0.65 in FY21 to 0.35 in FY25. Keep that borrowing in mind when reading the returns on this page.

Debt-to-equity shows how much of the business is paid for with borrowed money. Lower is safer, and the direction matters as much as the level.

6.5% of Harmonic Inc.'s tradable shares are in short positions, which are bets that the price will fall, so some traders are betting against it. At normal trading volumes, closing those positions would take about 4.4 days. US companies do not publish a quarter-by-quarter list of owners, so this page uses short interest instead.

There is no quarter-by-quarter list of owners here, so we look at short interest: the share of tradable shares held in short positions, which gain if the price falls.

It is a single reading at one point in time; we do not have its history.

Why it is at this level: the figure does not say who has the short positions or why, so we show the level without guessing the story.

For Harmonic Inc., the Z-score is 0.20. A Z-score above about 3 is safe and below about 1.8 signals danger, so this is in the danger zone. It estimates how far the balance sheet is from trouble; it is not a forecast of failure.

The Z-score estimates how far a company is from balance-sheet trouble. Above about 3 is safe; below about 1.8 is the danger zone. It was built for manufacturers, so it is not used for banks and lenders.

Why it matters: a Z-score of 0.20 is inside the danger zone, so the balance sheet is a real risk.

56.7 out of 100, rank 7 of 29 in Communication Equipment, with 56% of the evidence available.

Harmonic Inc. scores 56.7 out of 100 against the 29 companies it is compared with in Communication Equipment, ranking 7. Some evidence is missing, so the score is pulled toward the middle on purpose.

The four parts add up to the total exactly: 22.2 + 14.3 + 11.1 + 9.1 = 56.7. This is the same number shown on the industry page; it is worked out once for the whole group and read here.

What would change it: The score would fall if profit growth turns negative or margins stop improving while the share price lags its sector.

Harmonic ranks 7 of 29 Communication Equipment companies on the 4-Factor Sector Score, with 56.7 out of 100.

Missing figures are not scored as bad. They lower the confidence and pull the final score toward the middle. Relative strength counts only when the company has a reading for this week; with no reading, that factor is left out and its 20 points are shared across the other three in proportion. PEG is not shown when the ratio cannot mean anything: the company must be making a profit, its price-to-earnings must be positive, and its three-year earnings growth must fall between 5% and 60%. Dividing a price multiple by a loss, or by growth measured off a tiny base, produces a number that looks precise and tells you nothing. Under relative strength, one mark per week shows the last 12 weeks: a mark is filled where the company led S&P 500 by 5% or more over the 13 weeks ending that week, which is the same test used everywhere on this site. Price stage places the company on the same six-step path the industry is placed on (basing, turning, breaking out, leader, fading, asleep), read from how many weeks running it has led S&P 500 and whether that lead is growing or shrinking. It describes where the share price stands, not the direction of earnings, and it is not a recommendation; it is left blank for a company whose weekly history is too short or too stale to read.

The figures in this ranking come from the industry comparison: results through the Sep 2026 quarter, and the P/E at that quarter's end. The sections above use the latest weekly price, so a P/E or return there can differ a little from the one here. The stage words in this ranking (such as losing its lead or breaking out) describe the lead over the index, not the price phase in the price section.
