Corporate Governance Analyst

Routine late filing due to final review; company seeks 15‑day relief.

Flag Ship Acquisition Corp states it needs more time to finish its financial statement review for the year ended December 31, 2025 and expects to use the 15‑day extension available under Rule 12b-25. This is a procedural delay tied to closing controls and disclosure completion.

Timing and completion depend on the final review and any auditor deliverables; subsequent filings will show whether the delay affected reported results. Future periodic filings will confirm whether the extension resolved outstanding issues.
