Heights Capital Management, the institutional investor behind a $2 billion IonQ stock offering, also is leading a $200 million offering and private placement of SEALSQ stock.

SEALSQ, one of many players in the quantum-safe security arena, announced the offering and private placement on Oct. 15. The company’s press release described the pricing of a $94.8 million registered offering and a $105.2 million concurrent private placement, further stating the offerings are being led by Heights Capital Management, Inc., which also led a $2 billion IonQ offering announced last week.

More from the SEALSQ statement: “The Registered Offering consists of 12,640,000 ordinary shares at an offering price of $7.50. The Private Offering consists of pre-funded warrants to purchase 14,026,666 ordinary shares and Class D warrants to purchase up to 53,333,332 ordinary shares at a combined offering price of $7.50. The Class D warrants will have an exercise price of $9.25 per ordinary share, will be immediately exercisable and will expire seven years following the date of issuance. Gross proceeds for the Offerings are expected to be approximately $200.0 million before deducting commissions and offering expenses.”

The announcement came just a few days after SEALSQ, based in Cointrin, Switzerland, near Geneva, with US presence in Monument, Colorado, announced a $69 million warrant exercise transaction, which allowed Heights and other institutional investors to buy stock priced at $4.60.

Carlos Moreira, President and CEO of SEALSQ, said in the Oct. 15 release: “We plan to utilize the net proceeds to advance our Post-Quantum and Quantum roadmap, as SEALSQ has been rapidly expanding our portfolio in this field. We are executing with determination to deliver the most secure technologies to protect billions of connected devices through our post-quantum semiconductors and software solutions. This transaction represents a strong endorsement of our technical progress, strategic acquisitions, growing IP portfolio, and the exceptional talent we’ve assembled. With it, SEALSQ expects to benefit from a pro-forma cash position of approximately $400 million as of October 16, 2025, providing a solid foundation to fuel our next phase of growth.”

SEALSQ stock (NASDAQ: LAES) was $6.89 per share around mid-day Oct. 17. It was up more than 13% over the previous five days, and about 85% over the previous month.

SEALSQ is not what you would call a “pure play” quantum company, as it primarily works in the field of post-quantum cryptography (PQC)in addition to other semiconductor segments, though it also is moving into the area of “quantum as a service” and lists quantum sensing on its website under a “coming soon” header.

In addition to its financial news, SEALSQ also this week announced its QASIC quantum-resistant ASIC and further strategic plans for its acquisition of French ASIC firm IC’ALPS, announced earlier this year. It also recently announced US partnerships, including one with Brooklyn Park, Minnesota-based Trusted Semiconductor Solutions for “Made in US” PQC products.

All of the above is making SEALSQ one to watch in the quantum space, particularly as PQC adoption begins to take off.
