SEALSQ Corp: what insiders have been doing
SEALSQ Corp is a Technology company. Its directors and officers file their transactions with SEC (Form 4). From 22 October 2025 to 22 October 2026, the disclosure feed for SEALSQ Corp logged 28 filings by 5 insiders.
All open-market trades in the period are sales: 19 sales worth €560k, by 5 insiders, with no purchase on record. At €77k, the sale published on 7 October 2026 by Enguent Jean-Pierre is the largest of the period (0.016% of market cap).
Across the 3,171 companies tracked on its exchange, the median is 24 filings; at 28 filings, this issuer sits above that mark. Since 2026, the database holds no purchases and 19 sales by insiders of the company. In its latest annual report filed with the SEC (20-F, fiscal year ended 31 December 2025), the company reported revenue of 18.3 m USD and net income of -34.2 m USD.
Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.

About SEALSQ Corp
SEALSQ Corp (ticker: LAES) is a technology company listed on the NASDAQ in the United States. For French-speaking investors, it is best viewed as a specialist semiconductor and cybersecurity name operating at the intersection of secure hardware, public key infrastructure (PKI), and post-quantum security. The company’s stated mission is to design and commercialize products that secure identity, authentication, and communications at the silicon level, with an emphasis on future-proofing systems against quantum-computing threats.
SEALSQ was founded in 2022 as part of the WISeKey ecosystem and is structured as an international group with its operational base in Cointrin, near Geneva, Switzerland. Even though its operating headquarters are in Switzerland, the company trades in the U.S. on the NASDAQ, which makes it relevant to growth-oriented investors tracking cybersecurity, digital trust, and niche semiconductor plays.

The company’s core business is organized around three main pillars: secure semiconductors, PKI-based trust services, and post-quantum hardware/software solutions. In practical terms, SEALSQ develops chips, modules, and related technologies intended for secure authentication, IoT devices, critical infrastructure, and other use cases where embedded security is essential. Its commercial narrative is based on “security by design,” meaning protection is built into the hardware architecture rather than added later through software alone. That approach is its key competitive advantage versus broader, more generalized semiconductor or cybersecurity peers.
From a competitive standpoint, SEALSQ remains a relatively small and highly specialized company, but it is positioned in a structurally attractive theme: the transition toward quantum-resistant security standards. The investment case is less about scale today and more about long-duration optionality, intellectual property, and early positioning in a market that may expand meaningfully as quantum adoption and quantum-risk awareness increase. The company also highlights ecosystem-building efforts through strategic investments and partnerships tied to the emerging quantum stack.
Recent news flow has been active. In 2026, SEALSQ announced audited FY2025 results, reiterated guidance, emphasized U.S. deployments of post-quantum semiconductor technology, expanded its quantum investment fund, and outlined additional “Quantum Made in USA” initiatives. It also disclosed a planned relocation of its Geneva headquarters to Pont-Rouge in August 2026, signaling operational expansion. For investors, SEALSQ is still a development-stage technology story, where execution, commercialization, and conversion of its pipeline will be the key variables to watch.
