REVENUE
    
Contract Balances

    Contract assets (unbilled receivables) represent revenue recognized on contracts using an over time recognition model in excess of amounts invoiced to the customer. Contract liabilities (deferred revenue) represent customer advances and billings in excess of revenue recognized and are included within accrued expenses and other current liabilities and other long-term liabilities in the Company’s Consolidated Balance Sheets.

The following table presents the Company’s contract assets and liabilities (in thousands):

As of October 31,
20252024
Contract assets, current $119,257 $112,235 
Contract liabilities, current (79,529)(83,903)
Contract liabilities, long-term(84,714)(61,843)
Total contract liabilities (164,243)(145,746)
Net contract liabilities($44,986)($33,511)

    The increase in the Company's total contract liabilities during fiscal 2025 principally reflects the receipt of advance deposits on certain customer contracts, mainly at the FSG.

The amount of revenue that the Company recognized during fiscal 2025 that was included in contract liabilities as of the beginning of fiscal 2025 was $74.9 million.
    
Remaining Performance Obligations

Backlog, which the Company believes to be the equivalent of its remaining performance obligations, represents contractually committed, or firm customer orders. As of October 31, 2025, the Company had $2,107.6 million of remaining performance obligations associated with firm contracts pertaining to many of the products offered by the FSG and ETG. The Company will recognize net sales as these obligations are satisfied. The Company expects to recognize $1,358.7 million of this amount during fiscal 2026 and $748.9 million thereafter, of which more than half is expected to occur in fiscal 2027.

About Revenue Disclosures

Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.

Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
