Indicate by check mark whether the registrant is an emerging growth company as defined in Rule 405 of the Securities Act of 1933 (§230.405 of this chapter) or Rule 12b-2 of the Securities Exchange Act of 1934 (§240.12b-2 of this chapter).

Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

As previously disclosed, on April 5, 2024, Akari Therapeutics, Plc (the “Company”) received a letter from the Listing Qualifications Staff (the “Staff”) of The Nasdaq Capital Market (“Nasdaq”) indicating that it did not comply with the minimum $2,500,000 stockholders’ equity requirement for continued listing set forth in Listing Rule 5550(b) (the “Stockholders’ Equity Requirement”) (the “Original Notice”). At that time, the Company was provided 45 days to submit a compliance plan to regain compliance with the Stockholders’ Equity Requirement. On May 20, 2024, the Company submitted a plan to regain compliance with the Stockholders’ Equity Requirement (the “Compliance Plan”) for the Staff’s consideration. On August 5, 2024, the Company was notified by the Staff that it had been granted an extension until September 30, 2024 to comply with the Compliance Plan and evidence compliance with the Stockholders’ Equity Requirement.

On October 1, 2024, the Company received a delisting determination letter (“Delisting Determination Letter”) from the Staff notifying the Company that it did not meet the terms of an extension granted by Nasdaq to regain compliance with the Stockholders’ Equity Requirement. The Delisting Determination Letter states that unless the Company requests a hearing before a Nasdaq Hearing Panel (“Panel”) by October 8, 2024, trading of the Company’s American Depositary Shares (“ADSs”) will be suspended.

Accordingly, the Company intends to request a hearing before the Panel, which request will automatically stay any suspension/delisting action by the Staff at least until the hearing process concludes and any extension granted by the Panel expires. The Company expects that it will regain compliance with the Stockholders’ Equity Requirement upon closing of its pending merger with Peak Bio, Inc. (“Peak Bio”).

There can be no assurance that the Company will be able to regain compliance with the Stockholders’ Equity Requirement or will otherwise be in compliance with other applicable Nasdaq listing rules, that the Panel will grant the Company an additional extension period to remain listed on Nasdaq, or that the Company’s appeal of the delisting determination will be successful.
