INFORMATION CONTAINED IN THIS REPORT

Notification of Nasdaq Listing Deficiencies

On July 1, 2026, Blue Gold Limited (the “Company”) received a formal notification from Nasdaq stating that, based on the closing bid price of the Company’s class A ordinary shares of par value US$0.0001 per share (the “Class A ordinary shares”), for the last 30 consecutive business days, the Company’s Class A ordinary shares no longer comply with the minimum bid price requirement of $1.00 per share for continued listing on the Nasdaq Global Market, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Requirement”).

In addition, also on July 1, 2026, the Company received a separate formal deficiency letter from Nasdaq stating that the Market Value of Listed Securities (the “MVLS”) of the Company’s Class A ordinary shares has been below the $50 million minimum requirement for the preceding 30 consecutive business days, and that the Company therefore no longer meets the minimum MVLS requirement for continued listing on the Nasdaq Global Market, as set forth in Nasdaq Listing Rule 5550(b)(2) (the “MVLS Requirement”).

On July 8, 2026, the Company issued a press release announcing that the Company received a written notification from Nasdaq of the noncompliance with the Bid Price Requirement and a deficiency letter relating to the MVLS Requirement.

The notification and the deficiency letter have no immediate effect on the listing or trading of the Company’s Class A ordinary shares and the Company’s public warrants, which continue to be listed and to trade on Nasdaq. In accordance with Nasdaq Listing Rules, the Company was afforded a compliance period of 180 calendar days from the date of each notification, or until December 28, 2026 with respect to the Bid Price Requirement and the MVLS Requirement, to regain compliance.

To regain compliance with the Bid Price Requirement, the closing bid price of the Company’s Class A ordinary shares must be at least $1.00 per share for a minimum of 10 consecutive business days during the applicable compliance period. To regain compliance with the MVLS Requirement, the Company’s MVLS must close at $50 million or more for a minimum of 10 consecutive business days during the applicable compliance period.

In the event the Company does not regain compliance by December 28, 2026, the Company may be eligible for an additional 180 calendar day grace period. To qualify, the Company will be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for the Nasdaq Capital Market, with the exception of the Bid Price Requirement, and will need to provide written notice of its intention to cure the deficiency during the second compliance period, including by effecting a reverse stock split, if necessary. If the Company chooses to implement a reverse stock split, it must complete the split no later than ten (10) business days prior to December 28, 2026, or the expiration of the second compliance period if granted.  

A copy of the press release is furnished as Exhibit 99.1 to this Report of Foreign Private Issuer on Form 6-K and is incorporated herein by reference.
