Biggest thing to watch: the price is not yet in a clear uptrend, so timing is the risk more than the business. ## What is the Ciena share price today? Ciena Corporation's share price was $271.93 at the close on 4 November 2026. It has been moving sideways for 4 weeks. That is 33.0% below its average price over the last 200 trading days. In the last 52 weeks it traded between $178 and $584, and at that close it sat 23% of the way up from that low. Over the past 13 weeks it has done worse than the S&P 500, and it has been behind for 19 weeks running. Over the last 10 years the share price moved +1,324% 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 26 June 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. ## What dividend does Ciena pay? Ciena 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. ## Which stock lists is Ciena on?

## Is Ciena profitable? Ciena Corporation earned $266 M of net profit in the Aug 2026 quarter, +429.6% on the same quarter a year earlier. That is the 3rd quarter in a row of profit growth. Full-year FY25 profit was $123 M. Over 4 years profit has grown −29.5% a year on average. That is 15.9% of the quarter's revenue. The same quarter a year earlier earned $50.3 M. 1 of the last 12 reported quarters were loss-making. For the full year, FY25 profit was $123 M (+46.9% on the year before). Why profit moved: revenue changed +37.0% on a year earlier and the margin moved +11.9 percentage points. Most of the change came from keeping more of each sale. On average over the last four quarters, profit changed +738.1% and revenue +32.5%. Profit is growing faster than sales: fixed costs are spread over more sales, so each extra dollar of revenue adds more to profit. ## How much revenue does Ciena make, and is it growing? Ciena Corporation reported $1.7 B of revenue in the Aug 2026 quarter, +37.0% on the same quarter a year earlier. That is the 7th quarter in a row with growth on the year before. Over 4 years it has grown 7.1% a year on average. The last full year, FY25, came in at $4.8 B. The last four reported quarters add to $6.0 B. FY25 revenue was $4.8 B, +18.8% on the year before. Recent pace: the last four quarters grew +32.5% on average, against 7.1% 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 +32.6%, against +22.4% a year over the last 8 quarters (accelerating); profit over the last 12 months grew +364.5%, against +117.7% a year (accelerating). ## How much of every $100 of sales does Ciena keep? Ciena Corporation's operating margin was 18.1% in the Aug 2026 quarter, 11.9 percentage points higher than the same quarter a year ago. Across 5 years it has been between 4.8% and 13.4%. The latest quarter is above every full year in that period. Why the margin moved: operating margin changed +11.9 percentage points on the year while gross margin changed +4.1 points. So the gain came mostly from costs below the gross margin, such as staff and overheads, measured against sales. ## Is Ciena's profit turning into cash? Over the last 3 years, 322% of Ciena Corporation's reported profit came in as cash from its operations, so the profit is backed by cash. In FY25 it brought in $806 M of operating cash against $123 M of profit. After $141 M of spending on assets, $665 M was left over as free cash. 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. ## Where does Ciena's cash go? Ciena 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 $384 M on assets over the last 3 years. Averaged over those years that is 2.7% of FY25 revenue a year. Nothing is estimated in place of the missing day counts, so no cash-cycle chart is drawn. Spending on assets: $384 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. ## What is Ciena's P/E ratio, and how does it compare with its own history? Ciena Corporation's P/E is 60.8×, in the middle of its own history: higher than 53% of past readings. Its usual P/E (the middle reading) is 51.9×, over 4.5 years of weekly prices. This compares the share price with the company’s own past. It does not say what the business is worth. Why the multiple is where it is: over the past year earnings per share moved +46.6% while the price moved +36.5%. Earnings did better than the price, which pulled the multiple down within its own range. Where the price move came from: over 3 years the price moved +83.7% a year; about +37.9% a year came from earnings growth and about +45.8 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: the multiple is about average against its own past, so the earnings trend underneath matters more than the multiple. ## Is the Ciena business getting better or worse? Ciena Corporation's business is getting better. EPS growth hit its low 6 quarters ago at −64.5% and has recovered to +358.7%, with ROCE rising at 6.8%. This is based on 12 quarters of 4 measures. Why it matters: a lasting rise from a low is what this page is built to show. The latest quarter’s profit includes a one-off item bigger than the normal business, so the profit line is shown but does not count in this reading. ## How much does Ciena earn on its capital? Ciena Corporation earned a ROE of 5% in FY25. That is up from a low of 3% in FY24. Its return on capital used (ROIC) is 11.1 percentage points above its cost of capital, so growth here adds value, not just size. It comes from a 2.6% net margin and 0.81× asset turnover (sales divided by assets). Why the return is what it is (FY25): a 2.6% net margin × 0.81× asset turnover × 2.15× leverage (assets divided by equity) ≈ 4.5% 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: 22.0% − 10.9% = +11.1 percentage points. The 10.9% 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 22.0% ROIC above is the latest reading, as reported. The yearly chart below shows FY25 at 7.9%, and the quarterly chart works out each 12-month window from the quarterly figures, so the readings differ by date, not by method. ## Does Ciena have too much debt? Ciena Corporation has total debt of $3.3 B against shareholder equity of $3.1 B as of Aug 2026, so its debt is 1.07× its equity. Year by year, that ratio went from 0.27 in FY21 to 0.60 in FY25. Keep that borrowing in mind when reading the returns on this page. ## What is the Ciena shareholding pattern? 2.8% of Ciena Corporation'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 1.3 days. US companies do not publish a quarter-by-quarter list of owners, so this page uses short interest instead. 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 holds the short positions or why, so we show the level without guessing the story. ## How far is Ciena from balance-sheet trouble? For Ciena Corporation, the Z-score is 6.47. A Z-score above about 3 is safe and below about 1.8 signals danger, so this is well clear of danger. It estimates how far the balance sheet is from trouble; it is not a forecast of failure. Why it matters: a Z-score of 6.47 is well clear of the danger zone, so the balance sheet is not the risk here. ## How does Ciena rank in its industry? 54.3 out of 100, rank 9 of 29 in Communication Equipment, with 85% of the evidence available. Ciena Corporation scores 54.3 out of 100 against the 29 companies it is compared with in Communication Equipment, ranking 9. Earnings are strong; relative strength in its sector is -21.4% and the one-year return is 36.5%. The four parts add up to the total exactly: 30.7 + 17 + 4.4 + 2.2 = 54.3. 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. ## Which companies is Ciena compared with? Ciena ranks 9 of 29 Communication Equipment companies on the 4-Factor Sector Score, with 54.3 out of 100. 1.

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.
