Notice

of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On

April 27, 2026, Cayson Acquisition Corp (the “Company”) received a written notice (the “Notice”)

from the Listing Qualifications Department of The Nasdaq Stock Market (“Nasdaq”) indicating that the Company is not

in compliance with Listing Rule 5450(a)(2) (the “Minimum Total Holders Rule”), which requires the Company to have

at least of 400 “Total Holders” (generally defined as both beneficial holders and holders of record) of the Company’s

ordinary shares for continued listing on the exchange.

The

Notice stated that no later than June 11, 2026, the Company is required to submit a plan to regain compliance with the Minimum Total

Holders Rule. If Nasdaq accepts the Company’s plan, Nasdaq may grant the Company an extension of up to 180 calendar days from the

date of the Notice to evidence compliance with the Minimum Total Holders Rule. If Nasdaq does not accept the Company’s plan, the

Company will have the opportunity to appeal the decision in front of a Nasdaq Hearings Panel. The Company intends to submit a plan with

Nasdaq on or before June 11, 2026 to maintain its Nasdaq listing.

“believe(s),” “predicts,” “potential,” “continue,” “future,” “opportunity,”

seek,” “intend,” “strategy,” or the negative version of those words or phrases or similar expressions are

intended to identify such forward-looking statements.

The

Company cautions readers not to place undue reliance upon any forward-looking statements, which speak only as of the date made. The Company

does not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements

to reflect any change in its expectations or any change in events, conditions or circumstances on which any such statement is based.
