Restructuring and Related Activities [Abstract] |
RESTRUCTURING CHARGES | RESTRUCTURING CHARGES France Restructuring In November 2023, the Company initiated an information and consultation procedure with the Works Council for its Valbonne, France workforce regarding a planned wind-down of Sangamo’s French research and development activities and a corresponding reduction in workforce, including planned closure of the Company’s cell therapy manufacturing facility and research labs in Valbonne, France. The information and consultation procedure with the Works Council resulted in the definition of an acceptable set of termination provisions including payouts to departing employees and were a required step before the Company could eliminate positions at Sangamo France. The information and consultation procedure of the Works Council was completed in the first quarter of 2024. On March 1, 2024, the Company’s Board of Directors approved the France Restructuring which resulted in the elimination of all 93 roles in France, or approximately 24% of the total global workforce. As a result, the Company terminated its research and development activities in France and has substantially completed making severance payments to its French employees as required by French law and the terms of the applicable collective bargaining agreements, and incurring other employee-related costs. A majority of expenses related to employee severance and notice period payments, benefits, contract termination costs, and other related restructuring charges for the France Restructuring were recognized during the year ended December 31, 2023. During the three months ended June 30, 2024, the Company recognized $2.4 million as expense relating to a terminated manufacturing-related supplier arrangement for costs that were incurred without economic benefit to the Company, included in general and administrative expense in the accompanying Condensed Consolidated Statements of Operations. During the three months ended September 30, 2024, the Company reached a settlement relating to the terminated manufacturing agreement and recognized $2.2 million as a reduction to general and administrative expenses in the accompanying Condensed Consolidated Statements of Operations. The expenses incurred during the three and nine months ended September 30, 2024 related to employee severance and notice period payments, benefits, other employee-related costs, and facility shutdown costs were not material. There were no material expenses or adjustments recorded during the three and nine months ended September 30, 2025. See Note 6 – Impairment of Long-Lived Assets and Write-Down of Assets Held For Sale for impairment considerations related to the France Restructuring. The France Restructuring and the cash payments related thereto were completed as of March 31, 2025. The Company will continue the long-term follow up for its clinical studies in France for previously dosed patients as required by regulations. November 2023 Restructuring On November 1, 2023, the Company executed a restructuring of operations and a corresponding reduction in workforce (the “November 2023 Restructuring”), designed to reduce costs and advance its strategic transformation into a neurology-focused genomic medicine company. The November 2023 Restructuring resulted in the elimination of approximately 162 roles, including 108 full-time employees and 54 contracted employees and eliminated open positions, in the United States, or approximately 40% of the total United States workforce at that time, and included one-time severance payments and other employee-related costs, including additional vesting of service-based stock compensation awards. The total restructuring charges are estimated to be approximately $7.8 million to $8.8 million, related to employee severance and notice period payments, benefits, Brisbane, California facility close-out costs, and other related restructuring charges for the November 2023 Restructuring, of which $0.9 million to $1.9 million is remaining to be incurred as of September 30, 2025. The Company incurred $0.2 million of expenses during the three and nine months ended September 30, 2024, of which $0.1 million is included in research and development expense and $0.1 million is included in general and administrative expense. No expense relating to the November 2023 Restructuring was recorded during the three and nine months ended September 30, 2025. The Company expects the remaining costs representing the close-out costs for the Brisbane, California facility to be complete in the next one to two years. The following table is a summary of accrued November 2023 Restructuring and France Restructuring charges included within other accrued liabilities on the Company’s Condensed Consolidated Balance Sheet as of September 30, 2025 (in thousands):
