Remaining Performance Obligations from Contracts with Customer

As of September 30, 2025, the aggregate amount of the transaction price allocated to remaining performance obligations that are unsatisfied or partially unsatisfied was approximately $6.4 billion. Remaining performance obligations typically include the remaining non-cancelable, committed and fixed portion of contracts for their entire duration and therefore it is not comparable to what the Company considers to be the next 12 months backlog. Given the profile of contract terms, the majority of this amount is expected to be recognized as revenue over the next three years.

Disaggregation of Revenue

The Company considers information that is regularly reviewed by its Chief Operating Decision Maker ("CODM") in evaluating financial performance to disaggregate revenue. Please see Note 22 — Segment Information and Sales to Significant Customers.
