Item 8.01. Other Events.
 
On September 21, 2026, StoneBridge Acquisition II Corporation (the “Company”) made available its Passive Foreign Investment Company (“PFIC”) Annual Information Statement for the taxable year ended December 31, 2025 (the “PFIC Annual Statement”) to holders of the Company’s Class A ordinary shares. The PFIC Annual Statement is intended to assist such shareholders who wish to make a qualified electing fund (“QEF”) election under Section 1295 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), with respect to their investment in the Company.
 
The Company makes no representation as to whether it was, or will be, classified as a PFIC for the taxable year ended December 31, 2025 or any other taxable year, and the delivery of the PFIC Annual Statement is not an admission of PFIC status. Shareholders are urged to consult their own tax advisors regarding the applicability and consequences of a QEF election and the U.S. federal income tax treatment of an investment in the Company.
 
A copy of the PFIC Annual Statement is filed as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
