As previously disclosed on a Form 6-K filed by Bit Origin Ltd.(the “Company”) on February 26, 2025, the Company received a written notice from the Listing Qualifications Staff of Nasdaq regarding the Company’s failure to comply with Nasdaq Listing Rule 5550(a)(2) on February 21, 2025, which requires listed securities to maintain a minimum bid price of $1.00 per share. A failure to comply with Nasdaq Listing Rule 5550(a)(2) exists when listed securities fail to maintain a closing bid price of at least $1.00 per share for 30 consecutive business days. Based on the closing bid price for the last 30 consecutive business days, the Company failed to meet the aforesaid requirement. The Company was provided a period of 180 calendar days, until August 20, 2025, to regain compliance.

On August 28, 2025, the Company received a written notice from Nasdaq (the “August 2025 Notice”) stating that, although the Company had not regained compliance with the minimum bid price requirement by August 20, 2025, in accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company is eligible for an additional 180 calendar day period, or until February 16, 2026, to regain compliance with Nasdaq Listing Rule 5550(a)(2). To regain compliance, the closing bid price of the Company’s ordinary shares must meet or exceed $1.00 per share for a minimum of 10 consecutive business days during this 180-day period.

The August 2025 Notice has no immediate impact on the listing of the Company’s ordinary shares, which will continue to be listed and traded on the Nasdaq Capital Market, subject to the Company’s compliance with the other listing requirements of the Nasdaq Capital Market. Although the Company will use all reasonable efforts to achieve compliance with Rule 5550(a)(2), there can be no assurance that the Company will be able to regain compliance with that rule or will otherwise be in compliance with other Nasdaq listing criteria.

On August 29, 2025, the Company issued a press release entitled “Bit Origin Receives 180-Day Extension from Nasdaq to Regain Compliance with Minimum Bid Price Requirement” A copy of the press release is furnished herewith as Exhibit 99.1 and is incorporated herein by reference.

Exhibit 99.1

Bit Origin Receives 180-Day Extension from Nasdaqto Regain Compliance with Minimum Bid Price Requirement

August 29, 2025 (Singapore) – Bit Origin Ltd (NASDAQ: BTOG) ("Bit Origin" or the "Company"), today announced that it has received a notification letter from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) granting the Company an additional 180-calendar-day compliance period, or until February 16, 2026, to regain compliance with the minimum bid price requirement under Nasdaq Listing Rule 5550(a)(2).

As previously disclosed, on February 21, 2025, Nasdaq notified the Company that its listed securities did not meet the minimum bid price requirement of $1.00 per share over the preceding 30 consecutive business days. The initial 180-day compliance period expired on August 20, 2025.

The additional compliance period is granted based on the Company's compliance of all other continued listing requirements for the Nasdaq Capital Market, except for the bid price requirement, and providing written notice of its intention to cure the deficiency during the second compliance period by effecting a reverse stock split, if necessary.

To regain compliance, the Company’s ordinary shares must maintain a closing bid price of at least $1.00 per share for a minimum of ten consecutive business days during the compliance period. If the Company does not regain compliance by February 16, 2026, Nasdaq will provide written notification that the Company’s securities are subject to delisting. At that time, the Company would have the right to appeal the determination to a Nasdaq Hearings Panel.

This notification from Nasdaq has no immediate effect on the listing or trading of the Company’s ordinary shares, which will continue to trade on the Nasdaq Capital Market under the symbol “BTOG.”
