The Nasdaq Stock Market has initiated procedures to delist Cayson Acquisition Corp's securities because the company failed to provide necessary shareholder figures within an allotted extension period, thereby failing to comply with Listing Rule 5450(a)(2). This rule requires a minimum of 400 total holders for continued listing. The company received notice of this failure on October 29, 2026, and has filed an appeal by the November 5, 2026 deadline to maintain its listing status while it attempts to provide the required documentation. Cayson Acquisition Corp is a blank check company organized as a SPAC focused on completing an initial business combination.
