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 Mercury Systems share price today? Mercury Systems, Inc.'s share price was $80.32 at the close on 3 November 2026. It has been moving sideways for 11 weeks. That is 12.1% below its average price over the last 200 trading days. In the last 52 weeks it traded between $67 and $126, and at that close it sat 23% of the way up from that low.

Over the last 10 years the share price moved +215% while the S&P 500 moved +255%, 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. ## What dividend does Mercury Systems pay? Mercury Systems, 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 Mercury Systems on? Mercury Systems 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 Mercury Systems profitable? Mercury Systems, Inc. earned $798 K of net profit in the Jul 2026 quarter, −95.1% on the same quarter a year earlier. The full FY26 year was a loss of $29.7 M. That is 0.3% of the quarter's revenue. The same quarter a year earlier earned $16.4 M. 10 of the last 12 reported quarters were loss-making. ## How much revenue does Mercury Systems make, and is it growing? Mercury Systems, Inc. reported $290 M of revenue in the Jul 2026 quarter, +6.1% on the same quarter a year earlier. That is the 8th quarter in a row with growth on the year before. Over 5 years it has grown 1.3% a year on average. The last full year, FY26, came in at $984 M. The last four reported quarters add to $984 M. FY26 revenue was $984 M, +7.9% on the year before. Recent pace: the last four quarters grew +8.1% on average, against 1.3% 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 +7.9%, against +8.5% a year over the last 8 quarters (stabilising). ## How much of every $100 of sales does Mercury Systems keep? Mercury Systems, Inc.'s operating margin was 1.2% in the Jul 2026 quarter, 4.9 percentage points lower than the same quarter a year ago. Across 6 years it has been between −14.4% and 8.8%. The latest quarter is within that range. Why the margin moved: operating margin changed −4.9 percentage points on the year while gross margin changed −0.4 points. So the drop came mostly from costs below the gross margin, such as staff and overheads, measured against sales. ## Is Mercury Systems' profit turning into cash? Over the last 2 years, 107% of Mercury Systems, Inc.'s reported profit came in as cash from its operations, so the profit is backed by cash. In FY26 it brought in $102 M of operating cash against −$29.7 M of profit. After $34.3 M of spending on assets, $68.1 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 Mercury Systems' cash go? Mercury Systems, 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 $88.4 M on assets over the last 3 years. Averaged over those years that is 3.0% of FY26 revenue a year. Nothing is estimated in place of the missing day counts, so no cash-cycle chart is drawn. Spending on assets: $88.4 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 Mercury Systems' P/E ratio, and how does it compare with its own history? Mercury Systems, 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 Mercury Systems, Inc. at 4.9× its FY26 revenue of $984 M. The P/E comes back here once profit turns positive. ## Is the Mercury Systems business getting better or worse? Mercury Systems, 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 2 measures, with some gaps. Why it matters: with too little history, we say so rather than guess a direction. 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 Mercury Systems earn on its capital? Mercury Systems, Inc. earned a ROE of −2% in FY26. That is up from a low of −9% in FY24. Its return on capital used (ROIC) is 8.7 percentage points below its cost of capital, so growth here does not yet pay for the capital it uses. It comes from a −3.0% net margin and 0.42× asset turnover (sales divided by assets). Why the return is what it is (FY26): a −3.0% net margin × 0.42× asset turnover × 1.55× leverage (assets divided by equity) ≈ −2.0% on equity. The margin does its share; borrowing plays a small part, so this return is earned, not borrowed. The key test, return on capital used minus the cost of capital: 0.4% − 9.1% = −8.7 percentage points. The 9.1% 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 Mercury Systems have too much debt? Mercury Systems, Inc. has total debt of $503 M against shareholder equity of $1.5 B as of Jul 2026, so its debt is 0.34× its equity. Year by year, that ratio went from 0.18 in FY21 to 0.34 in FY26. Keep that borrowing in mind when reading the returns on this page. ## What is the Mercury Systems shareholding pattern? 10.0% of Mercury Systems, 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 9.4 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 Mercury Systems from balance-sheet trouble? For Mercury Systems, Inc., the Z-score is 4.34. 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 4.34 is well clear of the danger zone, so the balance sheet is not the risk here. ## How does Mercury Systems rank in its industry?
