As previously disclosed on its Current Report on Form 8-K on May 22, 2026, Akari Therapeutics, Plc (the "<u>Company</u>") entered into a securities purchase agreement (the "<u>Purchase Agreement</u>") with certain investors (the "<u>Investors</u>"), pursuant to which the Company agreed to sell and issue in a private placement (the "<u>Offering</u>") an aggregate of 1,470,588 unregistered American Depository Shares ("<u>ADSs</u>"), or prefunded warrants to purchase ADSs, each representing 80,000 of the Company's ordinary shares per ADS, together with Series H warrants, Series I warrants and Series J warrants to purchase an equivalent number of ADSs (the Series H, Series I, and Series J warrants collectively referred to as the "<u>Series Warrants</u>").

Under the Purchase Agreement, the gross proceeds of the Offering were to be funded in three separate tranches pursuant to three separate closings, the first of which occurred on May 27, 2026 (the "<u>First Closing Date</u>"), and the second and third closings were expected to occur on or about June 15, 2026 (the "<u>Second Closing Date</u>") and July 15, 2026 (the "<u>Third Closing Date</u>"), respectively.

Subsequent to the First Closing Date, on June 23, 2026, the Company and the Investors entered into an amendment to the Purchase Agreement (the "<u>Amendment</u>"), pursuant to which the parties agreed to combine the Second Closing Date and the Third Closing Date into one consolidated closing, which occurred on June 26, 2026 (the "<u>Combined Closing Date</u>"). Other than establishing the Combined Closing Date, no changes to the Purchase Agreement were made by the Amendment. On the Combined Closing Date, the Company issued and sold to the Investors the remaining 980,395 ADSs, or prefunded warrants in lieu thereof, due under the Purchase Agreement. Delivery of the Series Warrants is contingent upon receipt of shareholder approval at the Company's annual general meeting of shareholders to be held on June 30, 2026.

The foregoing summary of the terms of the Amendment is subject to, and qualified in its entirety by, the full text of such agreement, which is filed as Exhibit 10.1, to this Current Report on Form 8-K and is incorporated by reference herein.
