WISeKey International Holding Ltd. announced its unaudited first half 2023 (H1 2023) revenue of $15.1 million, a 39% increase from H1 2022. WISeKey operates as a holding company with four subsidiaries, each dedicated to a unique aspect of its expansive technology portfolio. WISeKey plans to further invest to mature each subsidiary and IPO each independent subsidiary upon reaching maturity.

Semiconductor revenue growth in H1 2023 was largely due to higher demand for semiconductors/IoT products.
