Note 1 - Closing of over-allotment option and additional private placement

The accompanying unaudited proforma balance sheet presents the balance sheet of Collective Acquisition Corp. II (the “Company”) as of April 30, 2026 adjusted for the closing of the underwriters’ overallotment option and related transactions, which occurred on June 12, 2026, as described below.

On April 30, 2026, the Company consummated the initial public offering (the “Initial Public Offering”) of 22,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units offered, the “Public Shares”) at $10.00 per Unit, generating gross proceeds of $220,000,000. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 5,837,500 private placement warrants (the “Private Placement Warrants”) at a price of $0.80 per Private Placement Warrant, in a private placement to the Company’s Sponsor, generating gross proceeds of $4,670,000. Each Unit consists of one Class A Ordinary Share, par value $0.0001 per share, and one-half of one redeemable warrant (the “Public Warrants”), each whole Public Warrant entitling the holder thereof to purchase one Class A Ordinary Share at an exercise price of $11.50 per share, subject to adjustment.

In connection with the Initial Public Offering, the underwriters were granted a 45-day option from the date of the Initial Public Offering to purchase up to an additional 3,300,000 Units to cover over-allotments if any. On June 12, 2026, the underwriters exercised their over-allotment option in full to purchase an additional 3,300,000 Units at $10.00 per Unit, generating gross proceeds of $33,000,000. As a result of the full exercise of the over-allotment option, 1,100,000 Founder Shares no longer subject to forfeiture.

As of June 12, 2026, a total of $33,165,000 of the net proceeds from the Initial Public Offering (including the full over-allotment close) and the sale of the Private Placement Warrants were placed in the trust account (the “Trust Account”).
