[1] | Primarily represents cost-reduction initiatives. Amounts associated with our Biopharma segment: (i) charges of $240 million for the three months ended September 28, 2025 (including charges of $117 million for our Manufacturing Optimization Program and charges of $107 million for our Realigning our Cost Base Program), (ii) charges of $451 million for the nine months ended September 28, 2025 (including charges of $669 million for our Realigning our Cost Base Program and credits of $295 million for our Manufacturing Optimization Program), (iii) charges of $141 million for the three months ended September 29, 2024 (primarily including charges for our Realigning our Cost Base Program) and (iv) charges of $1.2 billion for the nine months ended September 29, 2024 (including charges of $1.3 billion for our Manufacturing Optimization Program and credits of $69 million for our Realigning our Cost Base Program). For the nine months ended September 28, 2025 and September 29, 2024, Employee terminations include revisions of estimates of previously recorded accruals for severance benefits, driven in large part by higher-than-expected voluntary attrition.
