There are no material inventoried costs relating to over-time contracts where revenue is accounted for using the cost-to-cost method of accounting as of September 27, 2025 and September 28, 2024.

We have recorded inventory write-downs, primarily as a result of excess and obsolete inventories related to restructuring actions taken to close facilities and transfer remaining production and for the retirement or exiting the business of specific programs. See Note 14 - Restructuring and Note 22 - Segments, for additional disclosures relating to inventory write-downs.
