Accounting Policies [Abstract]

Basis of Preparation

Basis of Preparation and Principles of Consolidation

The unaudited consolidated financial statements have been prepared in conformity with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for annual financial statements and therefore should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

Principles of Consolidation

The unaudited consolidated financial statements reflect all adjustments (of a normal and recurring nature) that management considers necessary for a fair presentation of such statements for the interim periods presented. The unaudited consolidated statements of income for the interim periods presented are not necessarily indicative of the results for the full year or for any subsequent period.

The accompanying unaudited consolidated financial statements include the financial statements of ExlService Holdings and all of its subsidiaries. The standalone financial statements of subsidiaries are fully consolidated on a line-by-line basis. All intercompany balances and transactions are eliminated in consolidation. The Company’s investments in equity affiliates are recorded using equity method of accounting.

Use of Estimates

Use of Estimates

The preparation of the unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the carrying amounts of assets and liabilities and disclosure of contingent assets and liabilities included in the unaudited consolidated financial statements. Although these estimates are based on management’s best assessment of the current business environment, actual results may be different from those estimates. The significant estimates that affect the unaudited consolidated financial statements include, but are not limited to, estimates of the contingent consideration, credit risk of customers, the nature and timing of the satisfaction of performance obligations, the standalone selling price of performance obligations, variable consideration in a customer contract, expected recoverability from customers with contingent fee arrangements, estimated costs to complete fixed price contracts, assets and obligations related to employee benefit plans, deferred tax valuation allowances, income-tax uncertainties and other contingencies, valuation of derivative financial instruments and stock-based awards, and useful life of long-lived assets and other intangible assets. The significant assumptions underneath these estimates include, but are not limited to assumptions to calculate stock-based compensation expense, determine pattern of generation of economic benefits to calculate depreciation and amortization for long-lived assets and other intangible assets, and recoverability of long-lived assets, goodwill and other intangible assets.
