NOTE 1 - CLOSING OF OVER-ALLOTMENT OPTION AND ADDITIONAL PRIVATE PLACEMENT

The accompanying unaudited Pro Forma Balance Sheet presents the unaudited Balance Sheet of Catalyst Partners Acquisition Corp. (the “Company”) as of May 20, 2021, adjusted for the closing of the underwriter’s over-allotment option and related transactions which occurred on June 3, 2021 as described below.

The Company consummated its initial public offering (the “IPO”) of 30,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”), at $10.00 per Unit, generating gross proceeds of $300.0 million. Each Unit consists of one Class A ordinary share and one-fifth of one redeemable warrant (“Public Warrant”). Each whole Public Warrant will entitle the holder to purchase one Class A ordinary share at an exercise price of $11.50 per share, subject to adjustment.

The Company granted the underwriters in the IPO a 45-day option to purchase up to 4,500,000 Units, at $10.00 per Unit, to cover over-allotments, if any. On June 2, 2021, the underwriters partially exercised the option, and the closing of the issuance and sale of an additional 4,360,391 Units (the “Over-Allotment Units”) occurred on June 3, 2021, generating gross proceeds of approximately $43.6 million (the “Over-Allotment”). The underwriters forfeited the balance of the option. The Company incurred additional offering costs of approximately $2.4 million in connection with the Over-Allotment (of which approximately $1.5 million was for deferred underwriting fees).

Simultaneously with the closing of the IPO on May 20, 2021, the Company completed a private placement (the “Private Placement”) of an aggregate of 18,666,667 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) at a price of $0.60 per Private Placement Warrant to CAT Sponsor LLC, a Delaware limited liability company (the “Sponsor”), generating gross proceeds of approximately $11.2 million. On June 3, 2021, simultaneously with the issuance and sale of the Over-Allotment Units, the Company consummated the sale of an additional 1,453,464 Private Warrants at $0.60 per Private Placement Warrant (the “Additional Private Placement Warrants”), generating additional gross proceeds of approximately $872,000.

Upon the closing of the IPO, the Over-Allotment and the Private Placement, approximately $343.6 million ($10.00 per Unit) of the net proceeds of the sale of the Units and the Private Placement Warrants were placed in a  trust account (“Trust Account”) with Continental Stock Transfer & Trust Company acting as trustee and will be invested in United States government treasury bills with a maturity of 185 days or less or in money market funds investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended, or the Investment Company Act, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account.

In addition, the Sponsor and Catalyst Partners Foundation, a charitable foundation (the “Foundation”), agreed to forfeit 1,215,000 and 135,000 Founder Shares, respectively, on a pro rata basis, to the extent that the option to purchase additional Units was not exercised in full by the underwriters. The underwriters partially exercised their over-allotment option on June 3, 2021 and forfeited the remainder of the option; thus, 37,695 Founder Shares and 4,188 Founder Shares were forfeited by the Sponsor and the Foundation, respectively.

Unaudited Pro forma adjustments to reflect the exercise of the underwriters’ over-allotment option and the sale of the Private Placement Shares described above are as follows:
