On November 24, 2025, the parties amended the Ordinary Share SPA, to provide that at the Company’s option, the Company may sell the VWAP Purchase Shares either (i) at a price per share equal to (x) 0.95, multiplied by (y) the lower of (A) the Closing Sale Price on the applicable Trading Day and (B) the VWAP on the applicable Trading Day during a one (1)- day VWAP Purchase Valuation Period (as defined in the Ordinary Share SPA) or (ii) at a price per share equal to (x) 0.97, multiplied by (y) the lowest VWAP of the Class A ordinary shares during a three (3)- day VWAP Purchase Valuation Period.

Additionally, the VWAP Purchase Maximum Amount (as defined in the Ordinary Shares SPA) was amended to provide that the Company’s right to direct the Selling Shareholder to purchase Class A ordinary shares under the Ordinary Share SPA shall be limited to the amount of shares equal to the lower of: (i) the product (rounded up or down to the nearest whole number) obtained by multiplying (A) the daily trading volume in the Class A ordinary shares on the Trading Market (or Eligible Market, as applicable) on the applicable VWAP Purchase Exercise Date for such VWAP Purchase by (B) 0.20; and (ii) the quotient obtained by dividing (A) $2,000,000, by (B) the VWAP on the VWAP Purchase Exercise Date, and (b) respect to a VWAP Purchase made pursuant to Section 3.1 where the VWAP Purchase Valuation Period consists of three (3) Trading Days, such number of Class A ordinary shares equal to the lower of (i) the product (rounded up or down to the nearest whole number) obtained by multiplying (A) the daily trading volume in the Class A ordinary shares on the Trading Market (or Eligible Market, as applicable) on the applicable VWAP Purchase Exercise Date for such VWAP Purchase by (B) 0.40; and (ii) the quotient obtained by dividing (A) $3,000,000, by (B) the VWAP on the VWAP Purchase Exercise Date (in each case to be appropriately adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction during the applicable period); provided however, that the Selling Shareholder may waive this limit if Form F-3 is being used to register the Registrable Securities (as defined in the Registration Rights Agreement). All capitalized terms not defined in this paragraph shall have the meanings ascribed to them in the Ordinary Share SPA, as amended.

On August 29, 2025, Blue Gold Limited (the “Company”) entered into an Ordinary Share Purchase Agreement with Tumim Stone Capital LLC (the “Ordinary Share SPA”), pursuant to which the Company may, at its option, issue and sell up to an aggregate principal amount of $75 million in Class A ordinary shares, subject to certain conditions.

Tumim Stone Capital LLC is referred to herein as the “Selling Shareholder.”
