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 Arqit Quantum share price today? Arqit Quantum Inc.'s share price was $13.87 at the close on 4 November 2026. That is 22.9% below its average price over the last 200 trading days. In the last 52 weeks it traded between $12 and $34, and at that close it sat 9% 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 5 weeks running. Over the last 1 year the share price moved −60% 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 2 October 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 Arqit Quantum pay? Arqit Quantum Inc. pays no dividend. In the last 6 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 Arqit Quantum on? Arqit Quantum is on one of our US lists: US tech stocks. [US tech stocks](https://www.sectoralpha.in/us-tech-stocks)

## Is Arqit Quantum profitable? Arqit Quantum Inc. posted a net loss of $33.0 M in the Mar 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 $35.3 M. That loss is 5,302.1% of the quarter's revenue. The same quarter a year earlier earned $58.0 M. Read this profit with care: at −$33.0 M it is bigger than the quarter's whole revenue of $623 K. 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 −4,931.6% 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 Arqit Quantum make, and is it growing? Arqit Quantum Inc. reported $623 K of revenue in the Mar 2026 quarter, +829.9% on the same quarter a year earlier. Over 4 years it has grown 82.3% a year on average. The last full year, FY25, came in at $530 K. FY25 revenue was $530 K, +80.9% on the year before. Recent pace: the last four quarters grew +303.2% on average, against 82.3% a year over the longer run, so this year is growing faster than its own long-run rate. ## How much of every $100 of sales does Arqit Quantum keep? Arqit Quantum Inc.'s sales have fallen to very little: FY25 revenue was $530 K, against $7.2 M in FY22. On sales that small an operating margin is not a useful reading, so this section is left out until sales recover. ## Is Arqit Quantum's profit turning into cash? Arqit Quantum Inc.'s cash-flow history is too short to judge how much of its profit turns into cash. In FY25 its operations used $29.6 M of cash, against −$35.3 M of profit. After $33.0 K of spending on assets, free cash was −$29.6 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 Arqit Quantum's cash go? Arqit Quantum 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 $751 K on assets over the last 3 years. Averaged over those years that is 47.2% 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: $751 K 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 Arqit Quantum's P/E ratio, and how does it compare with its own history? Arqit Quantum 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 Arqit Quantum Inc. at 455.4× its FY25 revenue of $530 K. The P/E comes back here once profit turns positive. ## Is the Arqit Quantum business getting better or worse? Arqit Quantum 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. 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. 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. 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. ## How much does Arqit Quantum earn on its capital? Arqit Quantum Inc. earned a ROE of −130% in FY25. That is up from a low of −481% in FY24. Its return on capital used (ROIC) is left out: on sales this small it reads −412%, a number that says nothing useful about the business. ## Does Arqit Quantum have too much debt? Arqit Quantum Inc. has total debt of $2.2 M against shareholder equity of $28.5 M as of Mar 2026, so its debt is 0.08× its equity, which is very little. Year by year, that ratio went from 0.10 in FY22 to 0.03 in FY25. So the returns on this page come from the business, not from borrowed money. ## What is the Arqit Quantum shareholding pattern? 37.2% of Arqit Quantum 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 6.5 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 Arqit Quantum from balance-sheet trouble? For Arqit Quantum Inc., the Z-score is 11.52. 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 11.52 is well clear of the danger zone, so the balance sheet is not the risk here. ## How does Arqit Quantum rank in its industry?

The score ranks a company within its industry: each measure is scored against the other members.
