(1) The Private Warrants (and shares of common stock issued or issuable upon exercise of the Private Warrants) in general, will not be transferable, assignable or salable until 30 days after the Closing (excluding permitted transferees) and they will not be redeemable under certain redemption scenarios by us so long as they are held by the Sponsor, Metric or their respective permitted transferees. Otherwise, the Private Warrants have terms and provisions that are identical to those of the Public Warrants, including as to exercise price, exercisability and exercise period. If the Private Warrants are held by holders other than the Company’s sponsor, Metric or their respective permitted transferees, the Private Warrants will be redeemable by the Company under all redemption scenarios and exercisable by the holders on the same basis as the Public Warrants.

 

 

(2)

The Public Warrants became exercisable 30 days after the closing of the FLAG Merger. Each whole share of the warrant is exercisable for one share of the Company’s common stock.

 

The Company may redeem the outstanding Public Warrants for $1.92 per warrant upon at least 30 days’ prior written notice of redemption given after the warrants become exercisable, if the reported last sale price of the common stock equals or exceeds $34,560.00 per share (as adjusted for stock dividends, sub-divisions, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period commencing after the warrants become exercisable and ending on the third trading day before the Company sends the notice of redemption to the warrant holders. Upon issuance of a redemption notice by the Company, the warrant holders may, at any time after the redemption notice, exercise the public warrants on a cashless basis.

 

The Company accounts for the Public Warrants in accordance with the guidance contained in ASC 815-40. Such guidance provides that because the warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a liability.

 

The accounting treatment of derivative financial instruments in accordance with ASC 815 requires that the Company record a derivative liability upon the closing of the FLAG Merger (see Note 2).

 

On October 17, 2024, the Company received notice from the NYSE that the Company’s Public Warrants to purchase common stock are no longer suitable for listing pursuant to Section 1001 of the NYSE American Company Guide due to the low trading price of such public warrants, and that the NYSE Regulation has determined to commence proceedings to delist the public warrants. The Public Warrants may be traded on the OTC Pink Marketplace under the symbol CLDWW.
