SEALSQ Corp filings document the disclosures of a British Virgin Islands foreign private issuer developing semiconductor, PKI and post-quantum security products. Its Form 6-K reports furnish annual report materials, operating and financial results, AGM notices and outcomes, governance votes, and product or certification updates for secure-element and post-quantum hardware programs.
The filing record also covers registered direct offering documents, securities purchase and placement agency agreements, ordinary shares, pre-funded warrants, Class E warrants, shelf registration references and equity incentive registration statements. These disclosures describe capital-structure changes, material agreements, liquidity and revenue commentary, board composition, and shareholder voting mechanics.
Amendment No. 1 to Schedule 13G shows that WISeKey International Holding AG now holds 6,001,200 SEALSQ Corp (LAES) ordinary shares, equating to 4.85 % of the 123.7 million shares outstanding as of 30 Jun 2025. Because the economic stake has fallen below the 5 % threshold, Item 5 is tick-marked “Ownership of 5 percent or less.”
Despite the smaller ordinary-share position, WISeKey also owns 1,499,700 Class F shares. When combined with the ordinary shares, this block delivers 52.41 % of SEALSQ’s total voting power, leaving WISeKey in effective control of shareholder decisions. All voting and dispositive power over the disclosed ordinary shares is sole; there is no shared power reported.
The filing is informational only—no purchase, sale or agreement is disclosed—and is made under Rule 13d-1(c). Certified by CEO Carlos Moreira and CFO John O’Hara on 29 Jul 2025.
SEALSQ Corp (NASDAQ: LAES) has entered into a definitive agreement to raise approximately $60 million through a registered direct offering. On 14 July 2025 the company signed a Securities Purchase Agreement with institutional investors to issue 15 million Ordinary Shares at a combined price of $4.00 per share, each accompanied by one Class A and one Class B warrant.
Both warrant series are immediately exercisable, expire on 15 July 2032 and carry an exercise price of $4.60. Full exercise would add a further 30 million shares, taking total potential issuance to 45 million. The warrants include anti-dilution adjustments, cashless-exercise mechanics and a 4.99% (optionally 9.99%) beneficial-ownership cap. Class A warrants feature an additional Black-Scholes cash-put right upon a qualifying Fundamental Transaction.
Maxim Group LLC is acting as placement agent and will receive a 7% fee on gross proceeds plus up to $40,000 in reimbursable expenses. The transaction is being conducted under SEALSQ’s effective Form F-3 shelf (File No. 333-286098). Closing is expected on 15 July 2025, subject to customary conditions. The company does not intend to list the warrants on any exchange.
Investors gain clarity on near-term liquidity—net proceeds (after fees) will strengthen the balance sheet—yet face material dilution from the primary share issuance and any future warrant exercises.
