Contract Balances

Unbilled receivable and Contract assets: The timing of revenue recognition may differ from the timing of customer billing. When revenue is recognized prior to billing and the right to the amount due from customers is conditioned only on the passage of time, the Company records an unbilled receivable on its consolidated balance sheets. Unbilled receivables totaled $100.4 million at July 5, 2026, of which $68.2 million was included in “Accounts receivable, net” and $32.2 million was included in “Other assets, net” in the condensed consolidated balance sheet. Unbilled receivables totaled $105.6 million at December 28, 2025, of which $72.4 million was included in “Accounts receivable, net” and $33.2 million was included in “Other assets, net” in the condensed consolidated balance sheet. Unbilled receivables primarily related to software revenue. The Company had no material contract assets as of July 5, 2026 and December 28, 2025.

Deferred revenue and Customer deposits: Deferred revenue is recorded when revenue is recognized subsequent to customer invoicing. Deferred revenue is classified as either current in “Accrued expenses and other current liabilities” or as long-term in “Deferred taxes and other long-term liabilities” in the condensed consolidated balance sheets based on the timing of when the Company expects to recognize revenue. The deferred revenue balance is primarily related to the Company’s software as a service offerings, maintenance contracts and prepaid storage arrangements. Deferred revenue totaled $239.8 million at July 5, 2026, of which $174.3 million was included in “Accrued expenses and other current liabilities” and $65.5 million was included in “Deferred taxes and other long-term liabilities” in the condensed consolidated balance sheet. Deferred revenue totaled $224.8 million at December 28, 2025, of which $159.3 million was included in “Accrued expenses and other current liabilities” and $65.5 million was included in “Deferred taxes and other long-term liabilities” in the condensed consolidated balance sheet. The Company also had customer deposits received in advance of the transfer of control totaling $16.0 million and $19.3 million at July 5, 2026 and December 28, 2025, respectively, which was included in “Accrued expenses and other current liabilities” in the condensed consolidated balance sheet. The Company expects that these customer deposits will be recognized in revenue within three months of the balance sheet date.

Transaction price allocated to the remaining performance obligations

The Company applies the practical expedient and does not disclose information about remaining performance obligations that have original expected durations of one year or less. The estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the period are not material to the Company. The remaining performance obligations primarily include noncancelable purchase orders, noncancelable software subscriptions and cloud service contracts and long-term prepaid storage contracts.
