SEALSQ: Revenue Grew 131% and the Stock Fell 36% — the Price Is Now Mostly Cash

SEALSQ's first-half report, out Friday, reads like a clean growth story. Revenue nearly doubled, rising 131% to $11.2 million; the company reaffirmed full-year guidance of $27 million to $36 million; and management pointed to continued momentum in post-quantum chips. The stock tells a different story: it is down about 36% this year and trading just above its 52-week low. Both things are true at once, and the space between them — why a company can report 131% growth and still be sold off — is the real story here.

A growth headline on a loss-making base

The answer begins with the fact that this growth is small and deeply unprofitable. For the six months to the end of June, SEALSQ posted a net loss of $27.8 million, wider than the $20.0 million loss a year earlier, and a GAAP loss per share of -$0.13 on its ordinary shares. Operating losses reached $32.2 million, because research and development plus general and administrative costs grew faster than the top line. The 131% revenue jump is real, but it sits on a tiny starting point — H1 2025 revenue was just $4.8 million. The one genuinely encouraging line is gross margin, which improved to roughly 48%, a sign the underlying chip business can eventually scale to a decent margin. But that margin does not yet come anywhere near covering the cost structure, so growing revenue has not yet made the company profitable.

The price is mostly cash

The most important number in this report is not on the income statement. SEALSQ ended June with about $486 million in cash — nearly $495 million counting short-term investments — while the stock's total market value is roughly $526 million. Subtract the cash and the operating company itself carries an enterprise value of only about $100 million. In plain terms, the market is pricing most of this stock as a pile of cash and assigning the semiconductor business a small price tag.

That cash did not come from operations. It came from selling stock — including a $125 million registered direct offering in March — and it is being spent converting the pipeline into products. A business that recorded a $32 million operating loss in six months would eventually erode even a large cushion at the current pace. And the equity behind that cash is why per-share results look so much worse than the headline revenue: -$0.13 for ordinary shares and -$0.64 for the company's separate F share class, both reflecting a heavily layered share structure.

The path, and the clock

So the question is not whether SEALSQ beat the quarter, and not even whether it held guidance. It is whether the post-quantum products the cash is funding turn into real, profitable revenue. Management puts the active pipeline above $225 million through 2029, more than $100 million of it tied to post-quantum products. The QS7001 chip has cleared several certification steps, and the QVault TPM is being evaluated by roughly 30 prospective customers. But management expects the first commercial revenue only toward the end of 2026, with meaningful contribution pushed into 2027 as customers finish technical integration.

Read the two halves together and this stops being an earnings recap. The market has already stripped most of the operating value out of this stock in the 36% year-to-date slide; the price now rests largely on the cash balance, and the post-quantum business is on offer at around a $100 million enterprise value. That is cheap only if the pipeline converts and the loss shrinks as revenue scales. If the product revenue slips again, the cash cushion is what quietly erodes per-share value. For now the honest read is a wait: it is too early to call a turning point, but after this selloff the valuation has absorbed enough bad news that the next two to four quarters — first product revenue, and whether the burn comes down — decide whether this was a bargain or a slower leak.
