Performance Obligations

We regularly enter into contracts with multiple performance obligations. These contracts are believed to be firm as of the balance sheet date. However, we may allow customers to make product substitutions as we launch new products. The timing of shipments depends on several factors, including agreed upon shipping schedules, which may span multiple quarters. Most performance obligations are generally satisfied within approximately three tosix months after the contract execution date. As of September 28, 2025, the aggregate amount of the transaction price allocated to remaining performance obligations was $747 million, of which 77% is expected to be converted to revenue in the next twelve months,11% in the following twelve months, and the remainder thereafter.
