Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Hedge Accounting

The Company uses derivative instruments to mitigate cash flow volatility from risk of fluctuations in foreign currency exchange rates and interest rates. The Company enters into foreign currency forward contracts to hedge cash flow risks from forecasted transactions denominated in certain foreign currencies, and interest rate swaps to hedge cash flow risks from its revolving credit facility having variable interest rate obligations. These contracts qualify as cash flow hedges under ASC Topic 815, Derivatives and Hedging, and are with counterparties that are highly rated financial institutions.

The following table sets forth the aggregate notional amount of derivatives in cash flow hedging relationship:

As of

September 30, 2024

December 31, 2023

Foreign currency forward contracts denominated in:

Sell U.S. dollar (USD)

868,200

722,800

Interest rate swaps (Floating to fixed) denominated in:

USD

—

75,000

The Company estimates that approximately $7,631 of derivative gains, net, excluding tax effects, included in AOCI, representing changes in the value of cash flow hedges based on exchange rates prevailing as of September 30, 2024, could be reclassified into earnings within the next twelve months. As of September 30, 2024, the maximum outstanding term of the cash flow hedges was approximately 42 months.

The Company also enters into foreign currency forward contracts to hedge its intercompany balances and other monetary assets and liabilities denominated in currencies other than functional currencies, against the risk of fluctuations in foreign currency exchange rates associated with remeasurement of such assets and liabilities to functional currency. These foreign currency forward contracts do not qualify as fair value hedges under ASC Topic 815, Derivatives and Hedging. Changes in the fair value of these financial instruments are recognized in the unaudited consolidated statements of income and are included in the foreign exchange gain/(loss) line item. The Company’s primary exchange rate exposure is with the Indian rupee (INR), the Philippine peso (PHP), the U.K. pound sterling (GBP) and South African rand (ZAR). The Company also has exposure to the Colombian peso (COP), the Euro (EUR), the Australian dollar (AUD), the Canadian dollar (CAD) and other local currencies in which it operates.

The following table sets forth the aggregate notional principal amounts of outstanding foreign currency forward contracts for derivatives not designated as hedging instruments:


	As of
Foreign currency forward contracts denominated in:	September 30, 2024	December 31, 2023
Sell USD	200,322	170,543

Employee Benefit Plans

The Company’s Gratuity Plan in India (the “India Plan”) provides for a lump sum payment to vested employees on retirement or upon termination of employment in an amount based on the respective employee’s salary and years of employment with the Company. In addition, the Company’s subsidiary operating in the Philippines conforms to the minimum regulatory benefit, which provide for lump sum payment to vested employees on retirement from employment in an amount based on the respective employee’s salary and years of employment with the Company (the “Philippines Plan”). Liabilities with regard to the India Plan and the Philippines Plan are determined by actuarial valuation using the projected unit credit method. Current service costs for these plans are accrued in the year to which they relate. Actuarial gains or losses or prior service costs, if any, resulting from amendments to the plans are recognized and amortized over the remaining period of service of the employees.

The India Plan is partially funded whereas the Philippines Plan is unfunded. The Company makes annual contributions to the India Plan established with insurance companies. Fund managers manage these funds and calculate the annual contribution required to be made by the Company and manage the India Plan, including any required payouts. These funds are managed on a cash accumulation basis, inclusive of interest which is declared periodically. The Company expects to earn a return of approximately 7.2% per annum on the India Plan for the year ending on December 31, 2024.

Summary of Significant Accounting Policies	9 Months Ended
Summary of Significant Accounting Policies	Sep. 30, 2024
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies (a)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, 2023. 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. Intra-group balances and transactions, and gains and losses arising from intra-group transactions, are eliminated while preparing consolidated financial statements. The Company’s investments in equity affiliates are initially recorded at cost and any excess purchase consideration paid over proportionate share of the fair value of the net assets of the investee at the acquisition date is recognized as goodwill. The proportionate share of net income or loss of the investee after its acquisition is recognized in the unaudited consolidated statements of income. Accounting policies of the respective individual subsidiaries and equity affiliates are aligned wherever necessary, so as to ensure consistency with the accounting policies that are adopted by the Company under U.S. GAAP. (b)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 fair value of the identifiable intangible assets and contingent consideration, purchase price allocation, including revenue projections and the discount rate applied within the discounted cash flow model for business acquisitions, credit risk of customers, the nature and timing of the satisfaction of performance obligations, the standalone selling price of performance obligations, and 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 incremental borrowing rate to calculate lease liabilities and right-of-use (“ROU”) assets, determine lease term to calculate single operating lease cost, 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. (c)Recent Accounting Pronouncements In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. This ASU modifies the disclosure or presentation requirements of a variety of Topics in the Codification. Certain of the amendments represent clarifications to or technical corrections of the current requirements. For entities subject to the SEC’s existing disclosure requirements and for entities required to file or furnish financial statements with or to the SEC in preparation for the sale of or for purposes of issuing securities that are not subject to contractual restrictions on transfer, the effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The amendments in this ASU should be applied prospectively. For all entities, if by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the Codification and will not become effective for any entity. The adoption of this ASU will not have a material impact on the Company’s unaudited consolidated financial statements. The Company will continue to monitor for SEC action, and plan accordingly for adoption. In November 2023, FASB issued ASU No. 2023-07, Segment Reporting (“Accounting Standards Codification (“ASC”) Topic 280”): Improvements to Reportable Segment Disclosures. This ASU improves reportable segment disclosure requirements on an annual and interim basis for all public entities by requiring disclosure of significant segment expenses that are regularly reviewed by the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment's profit or loss and assets. The ASU also allows, in addition to the measure that is most consistent with U.S. GAAP, the disclosure of additional measures of segment profit or loss that are used by the CODM in assessing segment performance and deciding how to allocate resources. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of this ASU on its unaudited consolidated financial statements. In December 2023, FASB issued ASU No. 2023-09, Income Taxes (“ASC Topic 740”), Improvements to Income Tax Disclosures. This ASU expands disclosures relating to the entity’s income tax rate reconciliation, income taxes paid and certain other disclosures related to income taxes. The ASU will be effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of this ASU on its unaudited consolidated financial statements. (d)Recently adopted Accounting Pronouncements In March 2023, FASB issued ASU No. 2023-01, Leases (“ASC Topic 842”): Common Control Arrangements. This ASU provides guidance in ASC Topic 842 that leasehold improvements associated with common control leases should be (i) amortized by the lessee over the useful life of the leasehold improvements to the common control group, regardless of the lease term, as long as the lessee controls the use of the underlying asset through a lease, and (ii) accounted for as a transfer between entities under common control through an adjustment to equity if and when the lessee no longer controls the use of the underlying asset. The ASU is effective for fiscal years beginning after December 15, 2023. Early adoption is permitted for both interim and annual financial statements that have not yet been issued. When adopted in an interim period, it must be adopted from the beginning of the year that includes that interim period. The Company does not have any lease arrangements with entities under common control and the adoption of this ASU did not have a material impact on its unaudited consolidated financial statements.

Leases [Abstract]

Leases

The Company conducts its operations using facilities leased under operating lease agreements that expire at various dates. The Company finances its use of certain motor vehicles and other equipment under various lease arrangements provided by financial institutions. The lease agreements do not contain any covenants to impose any restrictions except for market-standard practice for similar lease arrangements.

The Company had performed an evaluation of its contracts with suppliers in accordance with ASC Topic 842, Leases, and had determined that, except for leases for office facilities, motor vehicles and other equipment as described above, none of the Company’s contracts contain a lease.

The components of lease cost, which are included in the Company’s unaudited consolidated statements of income, are as follows:


	Three months ended September 30,				Nine months ended September 30,
	2024		2023		2024		2023
Finance lease:
Depreciation on underlying ROU assets	$	111	$	50	$	261	$	127

Variable lease costs	1,240		1,170		3,329		3,334
Sub lease income	(49)		—		(49)		—
Total lease cost	$	7,350	$	6,084	$	20,763	$	18,695

(1) Includes short-term leases, which are immaterial.

Operating lease	4.9 years			5.6 years
Weighted average discount rate
Finance lease	14.9		%	14.2		%
Operating lease	7.9		%	7.4		%

As part of the Company’s efforts to optimize its existing network of operations centers, the Company continued to evaluate its office facilities to determine where it can exit or consolidate its use of office space. The Company modified certain of its operating leases, resulting in an increase of its lease liabilities by $3,383 and a decrease of its lease liabilities by $1,876, during the nine months ended September 30, 2024 and 2023, respectively, with a corresponding adjustment to ROU assets.

As of September 30, 2024 and December 31, 2023, the Company did not have any significant leases that have not yet commenced but that create significant rights and obligations for the Company.

Maturities of lease liabilities as of September 30, 2024 were as follows:

Accumulated Other Comprehensive Income (Loss), Net of Tax [Abstract]

Accumulated Other Comprehensive Income/(Loss)

Accumulated other comprehensive income/(loss) (“AOCI”) consists of actuarial gain/(loss) on retirement benefits and foreign currency translation adjustments. In addition, the Company enters into foreign currency forward contracts and interest rate swaps, which are designated as cash flow hedges and net investment hedges, as applicable, in accordance with ASC Topic 815, Derivatives and Hedging. Cumulative changes in the fair values of cash flow hedges are recognized in AOCI on the Company’s consolidated balance sheets. The fair value changes are reclassified from AOCI to unaudited consolidated statements of income upon settlement of foreign currency forward contracts designated as cash flow hedges of a forecast transaction, whereas such changes for interest rate swaps are reclassified over the term of the contract. Fair value changes related to net investment hedges are included in AOCI and are reclassified to unaudited consolidated statements of income when a foreign operation is disposed or partially disposed. The following table sets forth the changes in AOCI during the nine months ended September 30, 2024 and 2023:

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Capital Commitments As of September 30, 2024, the Company had committed to spend approximately $6,300 under agreements to purchase property and equipment. This amount is net of capital advances paid which are recognized in unaudited consolidated balance sheets as “Capital work in progress” under “Property and equipment.” On June 15, 2023, the Company, along with other limited partners, entered into a limited partnership agreement with the general partner, PNP Financial Services Fund GP I, LLC and initial limited partner and outgoing partner, to form a partnership with the name Plug and Play Financial Services Fund I, L.P. (the “Partnership”) for the primary purpose of making investments in growth-stage technology companies. During the nine months ended September 30, 2024, the Company further invested $600 in the Partnership and is committed under the Partnership to make further investments up to an amount of $2,800. Other Commitments Certain units of the Company’s Indian subsidiaries were established as 100% Export-Oriented units or under the Software Technology Parks of India or Special Economic Zone scheme promulgated by the Government of India. These units are exempt from customs, central excise duties, and levies on imported and indigenous capital goods, stores, and spares. The Company has undertaken to pay custom duties, service taxes, levies, and liquidated damages payable, if any, in respect of imported and indigenous capital goods, stores and spares consumed duty free, in the event that certain terms and conditions are not fulfilled. The Company believes, however, that these units have in the past satisfied, and will continue to satisfy, the required conditions. The Company’s operations centers in the Philippines are registered as qualified Philippines Economic Zone Authority units, which provides the Company fiscal incentives on the import of capital goods and local purchase of services and materials. The Company is required to meet certain requirements to retain the incentives. The Company has complied, and intends to continue compliance, with the requirements to avail itself of the incentives. Contingencies The transfer pricing regulations in the countries where the Company operates require that controlled intercompany transactions be at arm’s-length. Accordingly, the Company determines and documents pricing for controlled intercompany transactions based on an economic analysis as prescribed in the respective regulations. The tax authorities have jurisdiction to review the Company’s transfer pricing. If the Company’s transfer pricing is challenged by the authorities, they could assess additional tax, interest and penalties, thereby impacting the Company’s profitability and cash flows. The Company is currently involved in transfer pricing and related income tax disputes with Indian tax authorities. The aggregate amount demanded by Indian tax authorities (net of advance payments) as of September 30, 2024 and December 31, 2023 is $37,144 and $36,694, respectively. The Company has made payments and/or provided bank guarantees against these demands in the amounts of $7,669 and $7,227, as of September 30, 2024 and December 31, 2023, respectively. The Company believes that its positions will more likely than not be sustained upon final examination by the tax authorities, and accordingly has not accrued any liabilities with respect to these matters in its consolidated financial statements. India’s VAT regime ended in June 2017 and was replaced by the current Goods and Service Tax (“GST”) regime. Pursuant to reviewing the Company’s annual VAT filings, the Indian tax authorities raised aggregate VAT demands for tax years 2015 and 2017, in the amounts of $5,455 and $5,493, as of September 30, 2024 and December 31, 2023, respectively. The Company has provided bank guarantees against these demands in the amounts of $5,455 and $4,570, as of September 30, 2024 and December 31, 2023, respectively. The GST authorities rejected the Company’s refunds claims in the amounts of $5,023 and $4,748 as of September 30, 2024 and December 31, 2023, respectively. The Company has filed appeals against these matters and believes that it is more likely than not that upon final examination its position will be sustained based on its technical merits. Accordingly, no provision was recognized as of September 30, 2024 and December 31, 2023, respectively. Some of the Company’s subsidiaries in India have undergone assessments with the statutory authority with respect to defined contribution plan. Except for some components of the assessments for which the Company has recognized a provision in the financial statements, the Company believes that the amount demanded by such authority is not a meaningful indicator of the potential liabilities of the Company, and that these matters are without merit. The Company is defending against the assessment orders and in one case, has instituted an appeal against the order before the relevant tribunal while also making a payment under protest of the amount demanded. As of the reporting date, the Company’s management does not believe that the ultimate assessments in any of these matters will have a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows. The Company will continue to monitor and evaluate its position based on future events and developments on these matters. From time to time, the Company, its subsidiaries, and/or their present officers or directors, may be or have been, named as a defendant in litigation matters, including employment-related claims. The plaintiffs in those cases seek damages, including, where applicable, compensatory damages, punitive damages and attorney’s fees. With respect to pending litigation matters as of the reporting date, the Company believes that the damages claimed are without merit, and the Company intends to vigorously defend them. The Company will continuously monitor developments on these matters to assess potential impacts to the financial statements. The outcomes of legal actions are unpredictable and subject to significant uncertainties, and thus it is inherently difficult to determine the likelihood of the Company incurring a material loss or quantification of any such loss. With respect to certain pending litigation matters as of the reporting date, the Company has made provisions based on information currently available, including its evaluation of the facts underlying each matter and legal counsel’s advice on the estimated losses or range of reasonably possible losses. Based on the Company’s assessment, including the availability of insurance recoveries, the Company’s management does not believe that currently pending litigation, individually or in aggregate, will have a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows. The Company will continuously monitor these matters to assess potential impacts to the financial statements.

(1) Represents money market funds which are carried at the fair value option under ASC Topic 825 “Financial Instruments”.

(2) Represents those short-term investments which are carried at the fair value option under ASC Topic 825 “Financial Instruments”.

(3) Contingent consideration is presented under “Accrued Expenses and Other Current Liabilities” and “Other Non-Current Liabilities,” as applicable, in the consolidated balance sheets.

Fair Value of Derivative Financial Instruments:

The Company’s derivative financial instruments consist of foreign currency forward contracts and interest rate swaps. Fair values for derivative financial instruments are based on independent sources including highly rated financial institutions and are classified as Level 2. Refer to Note 17 - Derivatives and Hedge Accounting to the unaudited consolidated financial statements for further details.

Fair Value of Contingent Consideration:

The fair value measurement of contingent consideration is determined using Level 3 inputs. The Company’s contingent consideration represents a component of the total purchase consideration for business acquisitions. The measurement is calculated using unobservable inputs based on the Company’s own assessment of achievement of certain performance goals. The Company estimated the fair value of the contingent consideration based on the Monte Carlo simulation model and scenario-based method. Refer to Note 10 - Business Combinations, Goodwill and Other Intangible Assets to the unaudited consolidated financial statements for further details.

The following table summarizes the changes in the fair value of contingent consideration:


	Three months ended September 30,				Nine months ended September 30,
	2024		2023		2024		2023
Opening balance	$	—	$	13,689	$	15,589	$	18,689

Payments	—		—		(15,000)		(5,000)
Closing balance	$	7,700	$	16,189	$	7,700	$	16,189

During the three and nine months ended September 30, 2024 and 2023, there were no transfers among Level 1, Level 2 and Level 3.

Financial Instruments Not Carried at Fair Value:

The Company’s other financial instruments not carried at fair value consist primarily of cash and cash equivalents (except investments in money market funds, as disclosed above), short-term investments (except investments in mutual funds, as disclosed above), restricted cash, accounts receivable, net, long-term investments, accrued capital expenditures, accrued expenses, client liabilities and interest payable on borrowings for which fair values approximate their carrying amounts. The carrying value of the Company’s outstanding credit facilities approximates their fair value because the Company’s interest rate yield is near current market rates for comparable debt instruments.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
Summary of Significant Accounting Policies (Policies)	Sep. 30, 2024
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, 2023.
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. Intra-group balances and transactions, and gains and losses arising from intra-group transactions, are eliminated while preparing consolidated financial statements. The Company’s investments in equity affiliates are initially recorded at cost and any excess purchase consideration paid over proportionate share of the fair value of the net assets of the investee at the acquisition date is recognized as goodwill. The proportionate share of net income or loss of the investee after its acquisition is recognized in the unaudited consolidated statements of income. Accounting policies of the respective individual subsidiaries and equity affiliates are aligned wherever necessary, so as to ensure consistency with the accounting policies that are adopted by the Company under U.S. GAAP.
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 fair value of the identifiable intangible assets and contingent consideration, purchase price allocation, including revenue projections and the discount rate applied within the discounted cash flow model for business acquisitions, credit risk of customers, the nature and timing of the satisfaction of performance obligations, the standalone selling price of performance obligations, and 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 incremental borrowing rate to calculate lease liabilities and right-of-use (“ROU”) assets, determine lease term to calculate single operating lease cost, 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.
Recent Accounting Pronouncements and Recently adopted Accounting Pronouncements	Recent Accounting Pronouncements In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. This ASU modifies the disclosure or presentation requirements of a variety of Topics in the Codification. Certain of the amendments represent clarifications to or technical corrections of the current requirements. For entities subject to the SEC’s existing disclosure requirements and for entities required to file or furnish financial statements with or to the SEC in preparation for the sale of or for purposes of issuing securities that are not subject to contractual restrictions on transfer, the effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The amendments in this ASU should be applied prospectively. For all entities, if by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the Codification and will not become effective for any entity. The adoption of this ASU will not have a material impact on the Company’s unaudited consolidated financial statements. The Company will continue to monitor for SEC action, and plan accordingly for adoption. In November 2023, FASB issued ASU No. 2023-07, Segment Reporting (“Accounting Standards Codification (“ASC”) Topic 280”): Improvements to Reportable Segment Disclosures. This ASU improves reportable segment disclosure requirements on an annual and interim basis for all public entities by requiring disclosure of significant segment expenses that are regularly reviewed by the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment's profit or loss and assets. The ASU also allows, in addition to the measure that is most consistent with U.S. GAAP, the disclosure of additional measures of segment profit or loss that are used by the CODM in assessing segment performance and deciding how to allocate resources. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of this ASU on its unaudited consolidated financial statements. In December 2023, FASB issued ASU No. 2023-09, Income Taxes (“ASC Topic 740”), Improvements to Income Tax Disclosures. This ASU expands disclosures relating to the entity’s income tax rate reconciliation, income taxes paid and certain other disclosures related to income taxes. The ASU will be effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of this ASU on its unaudited consolidated financial statements. (d)Recently adopted Accounting Pronouncements In March 2023, FASB issued ASU No. 2023-01, Leases (“ASC Topic 842”): Common Control Arrangements. This ASU provides guidance in ASC Topic 842 that leasehold improvements associated with common control leases should be (i) amortized by the lessee over the useful life of the leasehold improvements to the common control group, regardless of the lease term, as long as the lessee controls the use of the underlying asset through a lease, and (ii) accounted for as a transfer between entities under common control through an adjustment to equity if and when the lessee no longer controls the use of the underlying asset. The ASU is effective for fiscal years beginning after December 15, 2023. Early adoption is permitted for both interim and annual financial statements that have not yet been issued. When adopted in an interim period, it must be adopted from the beginning of the year that includes that interim period.

The Company has one class of common stock outstanding.

Share Repurchases


	Shares repurchased	Total consideration		Weighted average purchase price per share (1)
Three months ended September 30, 2024	91,565	$	3,346	$	36.54
Three months ended September 30, 2023	45,267	$	1,324	$	29.25

Nine months ended September 30, 2023	237,047	$	7,853	$	33.13

On October 5, 2021, the Company’s board of directors authorized a $300,000 (excluding excise tax) common stock repurchase program beginning January 1, 2022 (the “2022 Repurchase Program”).

On February 26, 2024, the Company’s board of directors authorized a $500,000 (excluding excise tax) common stock repurchase program beginning March 1, 2024 (the “2024 Repurchase Program”), and terminated the 2022 Repurchase Program on February 29, 2024.

On March 15, 2024, the Company entered into a 2024 ASR Agreement with Citibank to repurchase shares of its common stock for an aggregate purchase price of $125,000, as part of the Company’s 2024 Repurchase Program. Upon payment of the aggregate purchase price of $125,000, the Company received an initial delivery of 3,350,084 shares of its common stock at an initial price of $29.85 per share, representing 80% of the aggregate purchase price. The Company funded the repurchase with available cash on hand and borrowing from its revolving credit facility. The 2024 ASR Agreement is accounted for as a treasury stock transaction and forward stock purchase agreement indexed to the Company’s common stock. The forward stock purchase agreement was classified as an equity instrument under ASC Topic 815-40, Contracts in Entity's Own Equity, and deemed to have a fair value of zero at the effective date. The prepayment of $25,000 was initially recorded in additional paid-in

capital, which reflected the pending settlement of the 2024 ASR Agreement. Under the terms of the 2024 ASR Agreement, the ultimate number of shares of Common Stock that the Company repurchased was based on the average of the daily volume-weighted average prices of the Common Stock during the term of the 2024 ASR Agreement, less a discount and subject to adjustments pursuant to the terms and conditions of the 2024 ASR Agreement.

On July 19, 2024, upon final settlement of the 2024 ASR Agreement, the Company received 820,433 additional shares of its common stock based on a daily volume-weighted average price of $29.97 per share during the term of the 2024 ASR Agreement. The additional shares received were recorded as treasury stock at a fair market value of $33.96 per share, and $2,862 was recorded in additional paid-in capital.

Under the Company’s two repurchase programs, shares may be purchased by the Company from time to time from the open market and through private transactions, or otherwise, as determined by the Company’s management as market conditions warrant. Repurchases may be discontinued at any time by the management.

The Company purchased shares of its common stock, for a total consideration including commissions and excluding excise tax, under its two repurchase programs, as below:


	Shares repurchased	Total consideration		Weighted average purchase price per share
Three months ended September 30, 2024	1,738,114	$	59,346	$	34.14
Three months ended September 30, 2023	975,774	$	28,636	$	29.35

Nine months ended September 30, 2024	6,012,285	$	187,599	$	31.20
Nine months ended September 30, 2023	3,001,619	$	93,483	$	31.14

Repurchased shares have been recorded as treasury shares and will be held until the Company’s board of directors designates that these shares be retired or used for other purposes.

Pursuant to the Inflation Reduction Act, effective January 1, 2023, the Company is required to pay a 1% excise tax on the fair market value of each share of common stock repurchased, net of stock issuances. The Company recognized excise tax of $412 and $1,030, respectively, on repurchase of common stock as a part of cost of such repurchases for the three and nine months ended September 30, 2024.

Credit Agreement

The Company held a $300,000 revolving credit facility pursuant to its credit agreement (the “Credit Agreement”), dated as of November 21, 2017 with certain lenders and Citibank N.A. as Administrative Agent. The revolving credit facility originally had a maturity date of November 21, 2022 and was voluntarily pre-payable from time to time without premium or penalty.

On April 18, 2022, the Company and each of the Company’s wholly owned material domestic subsidiaries entered into an Amendment and Restatement Agreement with Citibank, N.A. as Administrative Agent, and certain lenders (the “2022 Credit Agreement”), pursuant to which the parties thereto amended and restated the Credit Agreement. Among other things, the 2022 Credit Agreement (a) provides for the issuance of new revolving credit commitments such that the aggregate amount of revolving credit commitments available to the Company is equal to $400,000; (b) extends the maturity date of the revolving credit facility from November 21, 2022 to April 18, 2027; and (c) replaces LIBOR with Secured Overnight Financing Rate (“SOFR”) as the reference rate for the U.S. dollar borrowings.

On August 9, 2024, the Company and each of the Company’s wholly owned material domestic subsidiaries entered into a First Amendment to Amended and Restated Credit Agreement with Citibank, N.A., as Administrative Agent, and certain lenders (the “2024 Credit Agreement”), pursuant to which the parties thereto amended and restated the 2022 Credit Agreement. Among other things, the 2024 Credit Agreement (a) provides for a $100,000 increase to the revolving credit commitments such that the aggregate amount of revolving credit commitments available to the Company is now equal to $500,000; and (b) provides for the issuance of a new term loan facility in the aggregate amount of $100,000 with an annual amortization of 5%. The increased credit facility and the new term loan facility both mature on April 18, 2027.

The 2024 Credit Agreement includes a letter of credit sub facility and is voluntarily pre-payable from time to time without premium or penalty. Borrowings under the revolving credit facility can be used for working capital and general corporate purposes, including permitted acquisitions. Borrowings under the term loan facility can be used to repay the borrowings outstanding under the revolving facility on August 9, 2024, being the effective date of the 2024 Credit Agreement.

Obligations under the 2024 Credit Agreement are guaranteed by the Company’s wholly-owned material domestic subsidiaries and are secured by all or substantially all of the Company’s and its material domestic subsidiaries’ assets. The 2024 Credit Agreement contains customary affirmative and negative covenants, including, but not limited to, restrictions on the ability to incur indebtedness, create liens, make certain investments, make certain dividends and distributions, enter into, or undertake, certain liquidations, mergers, consolidations or acquisitions and dispose of certain assets or subsidiaries.

The Company has fully drawn $100,000 under its term loan facility based on adjusted SOFR, and repaid the borrowings outstanding under its revolving credit facility to that extent.

The effective interest rates of the revolving credit facility and the term loan facility are as follows:


	Three months ended September 30,				Nine months ended September 30,

Income Tax Disclosure [Abstract]

Income Taxes

The Company determines the tax provision for interim periods using an estimate of its annual effective tax rate. Each quarter, the Company updates its estimate of annual effective tax rate, and if its estimated tax rate changes, the Company makes a cumulative adjustment.

The effective tax rate decreased from 24.4% during the three months ended September 30, 2023 to 22.6% during the three months ended September 30, 2024. The Company recorded income tax expense of $15,460 and $14,161 for the three months ended September 30, 2024 and 2023, respectively. The increase in income tax expense was primarily as a result of higher profit during the three months ended September 30, 2024, compared to the three months ended September 30, 2023, partially offset by higher excess tax benefits related to stock-based compensation during the three months ended September 30, 2024, compared to the three months ended September 30, 2023.

The effective tax rate increased from 20.8% during the nine months ended September 30, 2023 to 22.6% during the nine months ended September 30, 2024. The Company recorded income tax expense of $43,086 and $37,773 for the nine months ended September 30, 2024 and 2023, respectively. The increase in income tax expense was primarily as a result of higher profit during the nine months ended September 30, 2024, compared to the nine months ended September 30, 2023 and lower excess tax benefits related to stock-based compensation during the nine months ended September 30, 2024, compared to the nine months ended September 30, 2023.

During the nine months ended September 30, 2024, the Company’s subsidiaries in India repatriated $18,255 (net of $996 withholding taxes) to the United States.

Deferred income taxes recognized in OCI were as follows:


	Three months ended September 30,				Nine months ended September 30,
	2024		2023		2024		2023
Deferred taxes benefit / (expense) recognized on:

Segment and Geographical Information

Segment Reporting [Abstract]

Segment and Geographical Information

The Company is a provider of data analytics and digital operations and solutions.

The Company manages and reports financial information through its four reportable segments: Insurance, Healthcare, Analytics and Emerging Business, which reflects how management reviews financial information and makes operating decisions. These business units develop client-specific solutions, build capabilities, maintain a unified go-to-market approach and are integrally responsible for service delivery, customer satisfaction, growth and profitability.

The CODM generally reviews financial information such as revenues, cost of revenues and gross profit, disaggregated by the operating segments to allocate an overall budget among the operating segments.

The Company does not allocate and therefore the CODM does not evaluate, certain operating expenses, interest expense or income taxes by segment. Many of the Company’s assets are shared by multiple operating segments. The Company manages these assets on a total Company basis, not by operating segment, and therefore asset information and capital expenditures by operating segment are not presented.

The August 2024 acquisition of Incandescent Technologies, Inc. (“ITI Data”) is included in the Analytics reportable segment. Refer to Note 10 - Business Combinations, Goodwill and Other Intangible Assets to the unaudited consolidated financial statements for further details.

Revenues and cost of revenues for the three months ended September 30, 2024 and 2023, respectively, for each of the reportable segments, are as follows:

Business Combinations, Goodwill and Other Intangible Assets

Goodwill and Intangible Assets Disclosure [Abstract]

Business Combinations, Goodwill and Other Intangible Assets

Incandescent Technologies, Inc.

On August 1, 2024, the Company, through its wholly owned subsidiary Clairvoyant AI, Inc., completed the acquisition of ITI Data, a Nebraska corporation, pursuant to an equity securities purchase agreement dated July 31, 2024 (the "Purchase Agreement"). The Company purchased 100% of the issued and outstanding equity securities in ITI Data.

ITI Data is a data management solutions firm that works with the global banks, financial services and healthcare companies. It delivers enterprise business solutions for clients processing significant data volumes with complex data management requirements. The acquisition strengthens the Company’s ability to deliver reliable, data-driven insights to its clients and ultimately drive greater value and innovation across their operations.

The base purchase consideration payable at the closing of the transaction was $26,000, excluding cash acquired, debt and other estimated post-closing adjustments. The Purchase Agreement also allows the seller the ability to earn up to $13,000 of

contingent consideration, based on the achievement of certain performance goals by ITI Data during the two years ending July 31, 2026. The contingent consideration had an estimated fair value of $7,700, and has been presented as contingent consideration under “Accrued expenses and other current liabilities” and “Other non-current liabilities,” as applicable in the consolidated balance sheets. A portion of the purchase consideration otherwise payable was placed into escrow as security for the post-closing working capital adjustments and the indemnification obligations under the Purchase Agreement. To finance the acquisition, the Company utilized its available cash on hand.

The Company’s preliminary purchase price allocation to net tangible and intangible assets of ITI Data as of August 1, 2024 is as follows:


Intangible assets	$	10,720
Other assets, net	581
Goodwill	22,035



Total purchase consideration*	$	33,336

* Includes contingent consideration of $7,700 recognized at fair value as of the date of acquisition.

The fair value of assets acquired and liabilities assumed from the acquisition of ITI Data is based on a preliminary valuation and, as such, the Company's estimates and assumptions are subject to change within the measurement period. The Company is in the process of finalizing the adjustments related to debt, working capital position and other post-closing adjustments, which, when determined, may result in the recognition of additional assets or liabilities as of the acquisition date, and shall accordingly lead to finalization of the purchase consideration. The measurement period will not exceed one year from the acquisition date.

In connection with this acquisition, the Company recorded $10,420 in customer-related intangibles which are being amortized on a straight-line basis (which approximates the economic pattern of benefits) over the estimated weighted average amortization period of 5 years.

The ITI Data acquisition is treated as a stock acquisition for tax purposes.

The goodwill recognized represents the acquired capabilities, operating synergies and other benefits expected to result from combining the acquired operations with the Company’s existing operations. The goodwill has been assigned to the Company’s Analytics reportable segment based upon the Company’s assessment of nature of services rendered by ITI Data.

The results of operations of the acquired business and the fair value of the acquired assets and assumed liabilities are included in the Company’s unaudited consolidated financial statements with effect from the date of the acquisition. The acquisition did not materially impact the Company's financial position, results of operations or cash flows, and therefore, the Company has not provided unaudited supplemental pro forma results.

Goodwill

The following table sets forth details of changes in goodwill by reportable segment of the Company:


	Insurance		Healthcare		Emerging Business		Analytics		Total



Balance as of January 1, 2024	$	50,035	$	21,872	$	47,001	$	286,731	$	405,639

Balance as of September 30, 2024	$	50,147	$	21,867	$	46,883	$	308,766	$	427,663

As of September 30, 2024, the Company performed an assessment to determine whether events or circumstances exist that may lead to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The Company considered current and forecasted economic and market conditions and qualitative factors, such as the Company’s performance during the nine months ended September 30, 2024, business forecasts for the remainder of the year,

stock price movements, generation and availability of cash and expansion plans. The Company reviewed key assumptions, including revisions of projected future revenues for reporting units against the results of the annual impairment test performed during the fourth quarter of 2023. The Company did not identify any triggers or indications of potential impairment for its reporting units as of September 30, 2024.

The recoverability of goodwill is dependent upon the continued growth of cash flows from the Company’s business activities. This growth is based on business forecasts and improvement in profitability of its reporting units. The Company continues to maintain its focus on cultivating long-term client relationships as well as attracting new clients.
