Comment for Type of Reporting Person:
(1) This Schedule 13D relates to the securities of WISeQey Corp. ("WISeQey" or the "Issuer"), as successor to WISeKey International Holding AG ("WISeKey"). Prior to the completion of the cross-border merger (the "Merger") on October 1, 2026, this Schedule 13D related to the following classes of securities of WISeKey: Class B ordinary shares ("Class B Shares"), nominal value CHF 0.10 per share (represented in part by American Depositary Shares), and Class A ordinary shares, nominal value CHF 0.01 per share ("Class A Shares"). Following the Merger, the Reporting Person's WISeKey Class B Shares were exchanged for ordinary shares of WISeQey ("WISeQey Ordinary Shares") and the Reporting Person's WISeKey Class A Shares were exchanged for Class F Shares of WISeQey ("WISeQey Class F Shares"). Due to EDGAR structured data (XML) filing requirements effective for Schedule 13D filings, the cover page's numeric boxes (Rows 7 through 13) are limited to a single class of security and relate solely to the WISeQey Ordinary Shares.

Every ten (10) WISeQey Class F Shares are convertible at any time, at the option of the holder, into one WISeQey Ordinary Share. This comment shall serve as full disclosure of the Reporting Person's beneficial ownership of the WISeQey Class F Shares. As of the date hereof, the Reporting Person has sole voting power and sole dispositive power over 1,811,641 WISeQey Class F Shares (representing the exchange of 1,811,641 WISeKey Class A Shares), and no shared voting or dispositive power over any WISeQey Class F Shares.
