StoneBridge Acquisition II Corp Waives $10K Monthly Sponsor Admin Fees

What Happened StoneBridge Acquisition II Corporation filed an 8-K (Aug 14, 2026) disclosing that it entered into an Administrative Services Agreement with Scieniti LLC on September 30, 2025 under which the Company agreed to pay $10,000 per month for office space and administrative support. On August 10, 2026, the Company and Scieniti executed a waiver under which Scieniti irrevocably waived its right to receive those monthly fees for all periods commencing on or after October 1, 2025 through the earlier of the consummation of the Company’s initial business combination and the Company’s liquidation. The waiver is attached as Exhibit 10.1 to the filing.

Key Details

• Original Administrative Services Agreement date: September 30, 2025 (counterparty: Scieniti LLC, an affiliate of the sponsor Stonebridge Acquisition Sponsor II LLC).
• Waiver effective date: August 10, 2026; applies retroactively to periods beginning October 1, 2025.
• Amount waived: $10,000 per month in office, utilities and secretarial/administrative support fees.
• Waiver term: Until the earlier of the Company's initial business combination closing or the Company’s liquidation; waiver is described as irrevocable for the covered periods.

Why It Matters For investors, the waiver removes a recurring $10,000 monthly expense that would have been incurred for administrative services, which can help preserve the SPAC’s cash and improve short-term liquidity. It also signals direct financial support from a sponsor affiliate (Scieniti), since the affiliate agreed to forgo fees rather than the Company incurring the cost. The filing includes the full waiver as an exhibit for detailed review.
