The change in contract assets (liabilities), net, primarily resulted from increased services performed under contracts consisting of multiple tasks. During the three and six months ended July 26, 2025, we performed services and recognized $11.9 million and $33.4 million of contract revenues related to contract liabilities that existed at January 25, 2025.
Customer Credit Concentration

Customers whose combined amounts of accounts receivable and contract assets, net, exceeded 10% of total combined accounts receivable and contract assets, net as of July 26, 2025 or January 25, 2025 were as follows (dollars in millions):

July 26, 2025January 25, 2025
