As previously disclosed in the Reportd on Form 6-K dated on January 8, 2025 and June 30, 2025 of BIT ORIGIN LTD, an exempted company incorporated in the Cayman Islands (the “Company”), the Company received a written notice from The Nasdaq Stock Market LLC (“Nasdaq”) Listing Qualifications Department on January 3, 2025, notifying the Company that the Company no longer complies with Nasdaq Listing Rule 5550(b)(1), which requires companies listed on the Nasdaq Capital Market to maintain a minimum of $2,500,000 in stockholders’ equity for continued listing, and the Company’s Form 20-F for the year ended June 30, 2024 reported stockholders’ equity of $909,583.

In response, the Company submitted a compliance plan to Nasdaq on February 17, 2025, outlining a series of initiatives intended to restore compliance with the Rule. Based on its review of the submission, Nasdaq granted the Company an extension through June 30, 2025, to demonstrate compliance. 

On July 1, 2025, the Company received a letter from Nasdaq, stating that, based on the Company’s Report on Form 6-K dated June 30, 2025, Nasdaq has determined that the Company complies with Nasdaq Listing Rule 5550(b)(1).

Nasdaq will continue to monitor the Company’s ongoing compliance with the minimum stockholders’ equity requirement and, if at the time of its next periodic report, the Company does not evidence compliance with the minimum stockholders’ equity requirement, the Company may be subject to delisting. At such time, Nasdaq staff will provide written notification to the Company, which may then appeal the Nasdaq staff’s determination to a Hearings Panel.

On July 3, 2025, the Company issued a press release entitled “Bit Origin Ltd Regains Compliance with Nasdaq Listing Requirements of Minimum Stockholders’ Equity”. A copy of the press release is furnished herewith as Exhibit 99.1.
