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

The accompanying unaudited Pro Forma Balance Sheet presents the Balance Sheet of Oaktree Acquisition Corp. III Life Sciences (the “Company”) as of October 25, 2024 adjusted for the closing of the underwriters’ partial overallotment option and related transactions, which occurred on October 30, 2024, as described below.

On October 25, 2024, the Company consummated an initial public offering (the “IPO”) of 17,500,000 units (the “Public Units”) at $10.00 per Public Unit, each Public Unit being comprised of one Class A ordinary shares, $0.0001 par value per share (the “Public Shares”) and one-fifth of one redeemable warrant, each whole warrant being exercisable for one Class A ordinary share at an exercise price of $11.50 (subject to adjustment, as described in the final prospectus relating to the IPO) (the “Public Warrants”). In connection with the IPO, the Company also consummated a private placement (the “Private Placement”) of units (the “Private Placement Units”) pursuant to which Oaktree Acquisition Holdings III LS, LLC (the “Sponsor”) purchased 550,000 Private Placement Units at $10.00 per Private Placement Units, each Private Placement Unit being comprised of one Class A ordinary share, $0.0001 par value per share (the “Private Placement Shares”) and one-fifth of one non-redeemable warrant, each whole warrant being exercisable for one Class A ordinary share at an exercise price of $11.50 (subject to adjustment, as described in the final prospectus relating to the IPO) (the “Private Placement Warrants” and together with the Public Warrants, the “Warrants”).

In connection with the IPO, the underwriters were granted a 45-day option from the date of the final prospectus related to the IPO (the “Over-Allotment Option”) to purchase up to 2,625,000 additional Units (the “Option Units”) to cover over-allotments, if any. On October 30, 2024, the underwriters partially exercised their Over-Allotment Option to purchase an additional 1,699,029 Option Units at a purchase price of $10.00 per Unit, generating additional gross proceeds of $16,990,290. The underwriters forfeited their option to purchase an additional 925,971 Option Units.

Simultaneously with the sale of the Option Units, the Sponsor purchased an additional 33,981 Private Placement Units at a purchase price of $10.00 per Private Placement Unit, generating additional gross proceeds of $339,810. As a result of the underwriters’ election to partially exercise their overallotment option, 231,492 Class B ordinary shares, $0.0001 par value per share, of the Company were forfeited by the Sponsor.

As of October 30, 2024, a total of $191,990,290 of the net proceeds from the IPO (including the Option Units) and the sale of the Private Placement Units were placed in the Trust Account.
