Costs Associated with Exit/Disposal Form 8 K

Item 2.05 Costs Associated with Exit or Disposal Activities.

On July 31, 2024, HilleVax, Inc. (the "Company") announced a workforce reduction of approximately 41 employees, constituting approximately 40% of the Company's workforce. The Company is taking this action to reduce its operating expenses while maintaining core capabilities as the Company explores the potential for continued development of its HIL-214 and HIL-216 norovirus vaccine candidates as well as business development-related activities for these vaccine candidates. The workforce reduction was approved by the Company's board of directors on July 26, 2024.

The Company currently estimates that it will incur charges associated with the workforce reduction of approximately $3.4 million primarily related to employee severance payments, benefits and related termination costs. The Company expects that the reduction in force will be substantially complete with the majority of related charges recognized in the third quarter of 2024.

The estimates of the charges and expenditures that the Company expects to incur in connection with the workforce reduction, and the timing thereof, are subject to several assumptions and the actual amounts incurred may differ materially from these estimates. In addition, the Company may incur other charges or cash expenditures not currently contemplated due to unanticipated events that may occur, including in connection with the implementation of the workforce reduction.
