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 Pacific Biosciences of California share price today? Pacific Biosciences of California, Inc.'s share price was $2.44 at the close on 3 November 2026. That is 51.6% above its average price over the last 200 trading days. In the last 52 weeks it traded between $1 and $3, and at that close it sat 89% of the way up from that low. Over the past 13 weeks it has done better than the S&P 500, and it has stayed ahead for 6 weeks in a row. Over the last 1 year the share price moved +66% while the S&P 500 moved +21%, so it is ahead of the index over that whole period. 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 Pacific Biosciences of California pay? Pacific Biosciences of California, 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. ## Which stock lists is Pacific Biosciences of California on? Pacific Biosciences of California is not in the Nasdaq 100, the S&P 500 or the Dow Jones 30, and is not on the US tech stocks list. ## Is Pacific Biosciences of California profitable? Pacific Biosciences of California, Inc. posted a net loss of $44.7 M in the Jun 2026 quarter. That quarter includes a one-off gain bigger than its revenue, so the comparison with last year does not reflect normal business. The full FY25 year was a loss of $546 M. That loss is 114.7% of the quarter's revenue. The same quarter a year earlier lost $41.9 M. 11 of the last 12 reported quarters were loss-making. Read this profit with care: at −$44.7 M it is bigger than the quarter's whole revenue of $39.0 M. No business earns more than it takes in from sales, so this is a one-off item (for example a debt settlement, a tax write-back or an asset sale), not money the business earned. The underlying business is running at a −114.4% operating margin. The jump on last year, and any P/E built on this profit, come from the one-off, not from a real turn in earnings. ## How much revenue does Pacific Biosciences of California make, and is it growing? Pacific Biosciences of California, Inc. reported $39.0 M of revenue in the Jun 2026 quarter, −1.9% on the same quarter a year earlier. Over 4 years it has grown 5.2% a year on average. The last full year, FY25, came in at $160 M. The last four reported quarters add to $159 M. FY25 revenue was $160 M, +3.9% on the year before. Recent pace: the last four quarters grew +2.0% on average, against 5.2% a year over the longer run, so this year is growing slower than its own long-run rate. Is growth speeding up? Revenue over the last 12 months grew +2.0%, against −8.2% a year over the last 8 quarters (accelerating). ## How much of every $100 of sales does Pacific Biosciences of California keep? Pacific Biosciences of California, Inc.'s operating margin was −114.4% in the Jun 2026 quarter, 1.6 percentage points lower than the same quarter a year ago. Across 5 years it has been between −344.8% and −136.5%. The latest quarter is above every full year in that period. Why the margin moved: operating margin changed −1.6 percentage points on the year while gross margin changed −4.5 points. So the drop came mostly from the gross margin, which means input costs and prices charged. ## Is Pacific Biosciences of California's profit turning into cash? Pacific Biosciences of California, Inc.'s cash-flow history is too short to judge how much of its profit turns into cash. In FY25 its operations used $111 M of cash, against −$546 M of profit. After $2.7 M of spending on assets, free cash was −$114 M: it spent more than its operations brought in. Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year. 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 Pacific Biosciences of California's cash go? Pacific Biosciences of California, 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 $17.7 M on assets over the last 3 years. Averaged over those years that is 3.7% 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: $17.7 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. ## What is Pacific Biosciences of California's P/E ratio, and how does it compare with its own history? Pacific Biosciences of California, Inc. has no P/E right now, because its earnings are negative. The revenue and margin sections are where a turn would show first. Measured against sales instead, the market values Pacific Biosciences of California, Inc. at 4.7× its FY25 revenue of $160 M. The P/E comes back here once profit turns positive. ## Is the Pacific Biosciences of California business getting better or worse? Pacific Biosciences of California, 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 12 quarters of 1 measure, with some gaps. Why it matters: with too little history, we say so rather than guess a direction. 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. The return-on-capital line is not shown: net worth is negative, so a return on capital means nothing. The balance sheet is in distress, and this reading uses the growth lines alone. 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. ## How much does Pacific Biosciences of California earn on its capital? Pacific Biosciences of California, Inc. earned a ROE of −10,215% in FY25. Its return on capital used (ROIC) is 24.3 percentage points below its cost of capital, so growth here does not yet pay for the capital it uses. It comes from a −341.5% net margin and 0.20× asset turnover (sales divided by assets). Why the return is what it is (FY25): a −341.5% net margin × 0.20× asset turnover × 146.58× leverage (assets divided by equity) ≈ −10,011.4% 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: −15.4% − 8.9% = −24.3 percentage points. The 8.9% 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. ## Does Pacific Biosciences of California have too much debt? Pacific Biosciences of California, Inc.'s net worth is negative: it owes more than it owns, so a debt-to-equity ratio means nothing here. Year by year, that ratio went from 1.21 in FY21 to 131.32 in FY25. So the returns on this page come from the business, not from borrowed money. ## What is the Pacific Biosciences of California shareholding pattern? 15.4% of Pacific Biosciences of California, Inc.'s tradable shares are in short positions, which are bets that the price will fall, so a large group of traders is betting against it. At normal trading volumes, closing those positions would take about 2.6 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 Pacific Biosciences of California from balance-sheet trouble? For Pacific Biosciences of California, Inc., the Z-score is −4.88. 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. Why it matters: a Z-score of −4.88 is inside the danger zone, so the balance sheet is a real risk. ## How does Pacific Biosciences of California rank in its industry? There is no score against its industry: Pacific Biosciences of California, Inc. is not among the largest members shown in this industry comparison for Medical Devices. The score ranks a company within its industry: each measure is scored against the other members. Without that group there is no score, so none is shown. ## Which companies is Pacific Biosciences of California compared with?
