WISeKey Announces the Establishment of SEALCOIN AG Subsidiary

Special Purpose Vehicle to House Operations of the Revolutionary SEALCOIN Project

Zug, Switzerland, July 2, 2024 – WISeKey International Holding Ltd. (“WISeKey” or the “Company”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity and IoT company operating as a holding company, today announced that it is in the process of incorporating SEALCOIN AG, a Special Purpose Vehicle (“SPV”) that will house the decentralized technology project SEALCOIN. Incorporation of the SPV as a WISeKey subsidiary is expected to be completed in early July 2024 in cooperation with The Hashgraph Association, a Swiss-based association which is at the forefront of digital enablement and empowerment using the Hedera network. The Hashgraph Association will become a strategic investor to the SPV with additional details to be announced in the coming weeks.

The SEALCOIN project aims to underpin decentralization ambitions on a global scale, setting a new standard for secure and efficient decentralized transactions. The project began in January 2024 at WISeKey’s semiconductor subsidiary, SEALSQ Corp (“SEALSQ”) (NASDAQ: LAES), as a proof of concept.

“We have concluded that the operations of the SEALCOIN project will be best fit under SEALCOIN AG as a new WISeKey subsidiary moving forward,” noted Carlos Moreira, CEO of WISeKey. “This decision allows the project to not only leverage SEALSQ’s expertise in the semiconductor and PKI space, but to capitalize on the extensive cybersecurity expertise of WISeKey. We look forward to the launch of the SEALCOIN platform and tokens, and to the revolutionary advancements we expect the project to make in our continued pursuit of decentralization.”

Strategic investment from The Hashgraph Association will allow SEALCOIN to integrate its advanced decentralized solutions with the leading industrial and decentralized infrastructure provided by Hedera, to create a strong Decentralized Physical Infrastructure Networks (“DEPIN”) ecosystem, with the goal of revolutionizing the IoT landscape.

Incorporation of SEALCOIN AG in Switzerland reinforces WISeKey’s commitment to operating within the highest standards of regulatory excellence given Switzerland’s leadership in blockchain and DLT regulatory frameworks. The Company will align the practices of SEALCOIN AG with FINMA guidelines; launch and roll-out of the SEALCOIN platform and tokens is subject to completion of relevant regulatory processes in applicable jurisdictions.
