For 2025, the statement shows ordinary earnings of US$0.00 per Class A share per day and no cash or property distributions to shareholders.

StoneBridge Acquisition II Corporation reported a change to its related-party administrative services arrangement. The company had entered into an Administrative Services Agreement on September 30, 2025 with Scieniti LLC, an affiliate of its sponsor, under which it agreed to pay $10,000 per month for office space, utilities, and secretarial and administrative support.
On August 10, 2026, StoneBridge and Scieniti executed a waiver under which Scieniti irrevocably waived its right to receive these monthly fees for all periods starting October 1, 2025 through the earlier of the company’s initial business combination or its liquidation. This waiver reduces ongoing administrative fee obligations to the affiliate for that period. The waiver is documented in an exhibit to the report.
StoneBridge Acquisition II Corporation is a Cayman Islands-based blank check company seeking a business combination, with no operating business yet. As of June 30, 2026, it held $59.1 million in a Trust Account invested in money market funds and $211,791 in cash outside the trust, with total assets of $59.4 million.
For the six months ended June 30, 2026, it reported net income of $737,571, driven almost entirely by $1.04 million of dividend and interest income on Trust Account investments, offset by $298,034 of general and administrative expenses. Class A public shares are classified as temporary equity at a redemption value of $10.27 per share, totaling $59.1 million for 5,750,000 redeemable shares.
Management states that the company must complete a business combination by April 1, 2027, with optional three‑month extensions to October 1, 2027 if the sponsor funds up to $1.15 million. Because this liquidation deadline falls within one year of issuance and extensions are discretionary, the company concludes there is substantial doubt about its ability to continue as a going concern.
StoneBridge Acquisition II Corporation, a blank check company, reported net income of $387,601 for the three months ended March 31, 2026.

At quarter-end, the company held $58,558,815 in its Trust Account and cash of $329,698 for operations, with total assets of $59,032,012. There were 5,750,000 Class A public shares classified as redeemable and 1,916,667 Class B founder shares outstanding. Management discloses substantial doubt about the ability to continue as a going concern within one year, as the company has not yet completed a business combination and faces a deadline of April 1, 2027, extendable to October 1, 2027, to consummate a deal.

StoneBridge Acquisition II Corporation reported that director Richard Saldanha resigned from the board and all committees effective May 8, 2026. The company states his resignation was not due to any disagreement with management, the board, or company policies or practices.
Mr. Saldanha had previously received a one-time equity grant of 25,000 Class B ordinary shares on February 5, 2026, for his board service. These shares were transferred to him from the sponsor’s existing holdings and were set to vest upon completion of the company’s initial business combination, contingent on his continued board service.
Because he resigned before any business combination was consummated, the 25,000 Class B ordinary shares will automatically be returned to Stonebridge Acquisition Sponsor II LLC under the terms of the grant agreement.
