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 6 weeks running.

Over the last 1 year the share price moved −39% while the S&P 500 moved +18%, so it is behind the index over that whole period. It was last ahead over 13 weeks in the week of 25 September 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.

ProQR Therapeutics N.V. 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.

ProQR Therapeutics N.V. is not in the Nasdaq 100, the S&P 500 or the Dow Jones 30, and is not on the US tech stocks list.

ProQR Therapeutics N.V. posted a net loss of $8.7 M in the Jun 2026 quarter. The full FY25 year was a loss of $42.2 M. That loss is 99.6% of the quarter's revenue. The same quarter a year earlier lost $12.2 M. 12 of the last 12 reported quarters were loss-making.

Net profit is what is left after every cost, interest and tax. Earnings per share, dividends and book value all grow from it.

ProQR Therapeutics N.V. reported $8.8 M of revenue in the Jun 2026 quarter, +120.4% on the same quarter a year earlier. Over 4 years it has grown 61.9% a year on average. The last full year, FY25, came in at $16.3 M. The last four reported quarters add to $18.4 M.

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

FY25 revenue was $16.3 M, −16.4% on the year before.

Recent pace: the last four quarters grew +10.6% on average, against 61.9% 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 +7.5%, against +8.1% a year over the last 8 quarters (stabilising).

ProQR Therapeutics N.V. has almost no sales yet: FY25 revenue was $16.3 M. On sales that small an operating margin is not a useful reading, so this section is left out until sales grow.

ProQR Therapeutics N.V.'s cash-flow history is too short to judge how much of its profit turns into cash. In FY25 its operations used $52.8 M of cash, against −$42.2 M of profit. After $1.0 M of spending on assets, free cash was −$53.8 M: it spent more than its operations brought in.

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.

What to look at next: the main use of cash is spending on assets. The next section checks what that spending is building.

ProQR Therapeutics N.V. 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 $3.8 M on assets over the last 3 years. Averaged over those years that is 7.8% 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: $3.8 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.

ProQR Therapeutics N.V. 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 ProQR Therapeutics N.V. at 12.2× its FY25 revenue of $16.3 M. The P/E comes back here once profit turns positive.

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.

ProQR Therapeutics N.V.'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.

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.

ProQR Therapeutics N.V. earned a ROE of −85% in FY25. That is up from a low of −97% in FY22. Its return on capital used (ROIC) is 35.7 percentage points below its cost of capital, so growth here does not yet pay for the capital it uses.

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.

The key test, return on capital used minus the cost of capital: −30.0% − 5.7% = −35.7 percentage points. The 5.7% 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.

ProQR Therapeutics N.V. has total debt of $15.3 M against shareholder equity of $79.5 M as of Jun 2026, so its debt is 0.19× its equity, which is very little. Year by year, that ratio went from 0.53 in FY21 to 0.32 in FY25. So the returns on this page come from the business, not from borrowed money.

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.

We have no ownership or short-position figures for ProQR Therapeutics N.V., so this section says so rather than fill the gap. At normal trading volumes, closing those positions would take about 3.7 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.

For ProQR Therapeutics N.V., the Z-score is −3.28. 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 −3.28 is inside the danger zone, so the balance sheet is a real risk.
