SEALSQ commits $15 million for capacity on 12 satellites from WISeSat.Space, a company its own CEO runs
The chipmaker's binding deal for capacity on 12 WISeSat.Space satellites lands six weeks after it paid $10.79 a share in a PIPE that now sits 71% underwater. LAES shareholders hold the cash and carry the marks while SAIQ sits 71% below the entry price.

On October 26, 2026, SEALSQ−5.30% — SEALSQ, down 5.30 percent today Corp, the Geneva maker of post-quantum security chips, signed a binding letter of intent to pay an estimated $15 million for satellite capacity on twelve WISeSat.Space satellites, together with mission control, ground segment, spectrum-filing and operational support services 1. The deal seeds SEALSQ's planned Quantum Spatial Orbital Cloud, or QSOC, a roadmap of up to 100 satellites through 2033 1. Carlos Moreira is chairman and chief executive of the buyer, the seller and their parent, WISeQey Corp; the LOI remains subject to definitive agreements and board approvals, listed among its risks in the WISeSat.Space release 16.
SEALSQ's cash is far larger than its market value
SEALSQ shareholders hold both the cash and the risk. The chipmaker reported about $463 million in cash, cash equivalents and restricted cash at September 30, 2026, yet its stock closed at $1.26 on November 13, a market capitalization of roughly $280 million, below its own cash pile 35. It lost $27.8 million in the first half of 2026, a 39% widening year on year 5. The letter of intent is its second cash transfer to WISeSat.Space inside one month: a $10 million PIPE closed on October 1 at $10.79 a share, the SPAC redemption price 2.
SEALSQ's cash pile went from $2 million to $486 million in five years

The market has never paid the entry price
WISeSat.Space, trading as SAIQ since October 2, closed at $3.11 on November 13, down 8.8% on the day and 71% below the price SEALSQ paid six weeks earlier 4. Its 52-week high is $9.94, so no market buyer has ever matched the PIPE's $10.79 4. The company booked no revenue and a roughly $2.9 million net loss in the first half of 2026 4.

The seller flagged its own risks
The LOI remains subject to definitive agreements and board approvals, and the release lists "the related-party nature of the transaction" among its risks 1. Releases have come near-daily since: today WISeSat.Space published a satellite-security strategy naming SEALSQ's QS7001 post-quantum chip, in orbit since March 2026 6.
The deal's gap is the missing outside price
It is not automatically a bad deal. SEALSQ's nine-month revenue rose 65% to $16.3 million, full-year guidance of $27 million to $36 million stands reaffirmed, and a pipeline above $200 million runs through 2029 3. The Viasat KA-SAT hack of February 2022 showed satellite ground systems really do get attacked 6. The LOI could be cheap infrastructure for recurring space-enabled security subscriptions. What it lacks is any external price: buyer and seller share one chief executive, and no independent valuation has been published.
