Item 2.05 Costs Associated with Exit or Disposal Activities.

On May 1, 2024, Akari Therapeutics, Plc (the “Company”) began to implement a reduction-in-force of approximately 67% of its total workforce as a result of the recently announced program prioritization under which the Company's HSCT-TMA program was suspended. The reduction-in-force is part of an operational restructuring plan and includes the elimination of certain senior management positions. The purpose of the restructuring plan, including the reduction-in-force, is to reduce HSCT-TMA related operating costs, while supporting the execution of the Company’s long-term strategic plan.

The Company currently expects expenses related to the reduction-in-force, consisting primarily of cash severance and termination benefits and related costs, to be in the range of approximately $3.1 million to $3.2 million, which includes approximately $1.6 million of non-cash expenses related to vesting of equity awards. The Company expects these costs to be payable through the fourth quarter of 2024. These estimates are subject to a number of assumptions, and actual results may differ. The Company may also incur additional costs not currently contemplated due to events that may occur as a result of, or that are associated with, the operational restructuring plan, including the reduction-in-force.

Item 5.02 Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers.

On May 7, 2024, Rachelle Jacques resigned from the Board of Directors (the “Board”), effective May 7, 2024. In connection with Ms. Jacques’ resignation from the Board, the Board reduced its size to five members. There was no disagreement between Ms. Jacques and the Company on any matter related to the Company’s operations, policies or practices that led to Ms. Jacques’ resignation from the Board.
