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 Condensed Consolidated Balance Sheets.

    The following table presents the Company's contract assets and liabilities (in thousands):
As ofAs of
April 30, 2026October 31, 2025
Contract assets, current $131,590 $119,257 
Contract liabilities, current (132,070)(79,529)
Contract liabilities, long-term(71,122)(84,714)
Total contract liabilities (203,192)(164,243)
Net contract liabilities($71,602)($44,986)

The increase in the Company's contract assets during the first six months of fiscal 2026 principally reflects additional unbilled receivables on certain customer contracts using an over time recognition model in excess of billings, as well as the contract assets of a certain business acquired during fiscal 2026. The increase in the Company's total contract liabilities during the first six months of fiscal 2026 principally reflects the receipt of advance deposits on certain customer contracts, mainly at the FSG.

The amount of revenue that the Company recognized during the six and three months ended April 30, 2026 that was included in contract liabilities as of the beginning of fiscal 2026 was $55.8 million and $26.2 million, respectively.
    
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 April 30, 2026,
the Company had $2,622.6 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 $1,177.0 million of this amount during the remainder of fiscal 2026 and $1,445.6 million thereafter, of which the majority is expected to occur in fiscal 2027.
