Item 2.05

Costs Associated with Exit or Disposal Activities.

On August 29, 2023, Apellis Pharmaceuticals, Inc. (the "Company") announced a corporate restructuring, pursuant to which the Company (i) plans to continue to support the U.S. commercial launch of SYFOVRE and is preparing for potential ex-U.S.launches, with an anticipated decision on regulatory approval by the European Medicines Agency in early 2024, (ii) plans to reduce EMPAVELI expenses through a more focused commercial and medical PNH organization and prioritizing the development of systemic pegcetacoplan in patients with immune complex membranoproliferative glomerulonephritis ("IC-MPGN")and C3 glomerulopathy ("C3G") and not initiating any new clinical development programs with systemic pegcetacoplan and (iii) intends to prioritize research initiatives in retina and central nervous system diseases, intends to deprioritize certain development initiatives (including siRNA with systemic pegcetacoplan, APL-1030,and APL-2006),and plans to continue its collaboration with Beam Therapeutics, Inc.

In connection with the corporate restructuring, on August 28, 2023, the Company committed to a reduction in workforce of approximately 225 employees, or approximately 25% of its current workforce. The Company expects that the corporate restructuring and associated reduction in workforce will result in total cost savings of up to $300 million through 2024, which includes more than $70 million in expected net costs savings related to the reduction in workforce and up to $230 million related to elimination of planned external expenses. The Company anticipates that the reduction in workforce will be substantially completed in the third quarter of 2023.

As a result of the reduction in workforce, the Company estimates that it will incur approximately $9 million to $11 million in costs, substantially all of which are cash expenditures. These costs are anticipated to be incurred primarily in the second half of 2023. The estimate of costs that the Company expects to incur and the expected timing to complete the reduction in workforce are subject to a number of assumptions, and actual results may differ. The Company may also incur other cash or non-cashcharges or cash expenditures not currently contemplated due to events that may occur as a result of, or in association with, the reduction in workforce.

Item 8.01

Other Events.

In connection with the corporate restructuring, the Company also announced that it plans to provide an update on its expected cash runway in connection with its third quarter 2023 earnings update. Additionally, the Company announced that (i) 230 people in the United States were on commercial treatment with EMPAVELI as of June 30, 2023 and (ii) top-linedata from the Phase 3 VALIANT study in patients with IC-MPGNand C3G are expected in 2024.
