The increase in contract assets, net, primarily resulted from increased services performed under contracts consisting of multiple tasks. During the three and six months ended July 27, 2024, we performed services and recognized $2.9 million and $12.5 million, respectively, of contract revenues related to contract liabilities that existed at January 27, 2024. See Note 7, Other Current Assets and Other Assets, for information on our long-term contract assets.

Customer Credit Concentration

We have two customers whose combined amounts of accounts receivable and contract assets, net, exceeded 10% of total combined accounts receivable and contract assets, net. The combined amounts of accounts receivable and contract assets, net, for Lumen Technologies were $402.7, or 25.9%, and $345.0, or 27.4%, as of July 27, 2024 and January 27, 2024, respectively, and Charter Communications were $164.25, or 10.6%, and $108.2, or 8.6%, as of July 27, 2024 and January 27, 2024, respectively, of the total combined accounts receivable and contract assets, net. No other customer had combined amounts of accounts receivable and contract assets, net, which exceeded 10% of total combined accounts receivable and contract assets, net as of July 27, 2024 or January 27, 2024. We believe that none of our significant customers were experiencing financial difficulties that would materially impact the collectability of our total accounts receivable and contract assets, net, as of July 27, 2024 or January 27, 2024.
