As of December 31, 2025, the Company had foreign tax credit carryforwards of $33.9 million, all of which will expire between 2031 and 2035. As of December 31, 2025, the Company had foreign net operating loss and capital loss carryforwards of $154.2 million, of which $22.9 million expires over the next 15 years and $131.3 million can be carried forward indefinitely.

The valuation allowance for foreign deferred tax assets was $24.5 million and $9.6 million as of December 31, 2025 and 2024, respectively. The historical profitability of each foreign entity is a factor in determining whether to establish or release a valuation allowance. Pre-tax operating losses on a three-year cumulative basis or lack of sustainable profitability are considered objectively verifiable evidence and will generally outweigh a projection of future taxable income. Certain foreign subsidiaries have experienced cumulative operating losses over a three-year period and, as a result, have recorded a valuation allowance against all or a portion of their deferred tax assets. Based on all available evidence, we have determined that it is more likely than not (defined as a likelihood of greater than 50%) that the deferred tax assets held by these entities will not be realized and, consequently, have recorded valuation allowances on these deferred tax assets.

Changes in the valuation allowance for deferred tax assets for the years ended December 31, 2025, 2024 and 2023 was as follows:


	Year Ended December 31,
	2025		2024		2023

Income tax expense at federal statutory rate	$	73,662	$	75,256
State income taxes, net of federal benefit	13,508		12,562
Detriment from foreign tax rates	6,616		9,418

Other adjustments, net	(984)		(3,875)
Income tax provision	$	70,683	$	83,471

The income tax provision for the years ended December 31, 2025 and 2024 was $100.1 million and $70.7 million, respectively. The increase in the income tax provision was primarily due to a less favorable tax benefit related to share-based compensation, resulting from fewer non-qualified stock option exercises and an increase in valuation allowances against certain foreign deferred tax assets as compared to the prior year.

We file numerous consolidated and separate income tax returns in the U.S. federal jurisdiction and in many city, state and foreign jurisdictions. We are no longer subject to U.S. federal income tax examinations for years prior to 2022. We are also no longer subject to state and local or foreign tax examinations by tax authorities for years prior to 2019.

Our liability for uncertain tax positions was $0.5 million and $0.7 million as of December 31, 2025 and 2024, respectively. As of December 31, 2025, our accrual for the payment of tax-related interest and penalties was not significant.

Recent Legislation

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The OBBBA is expected to have immaterial impacts on the current and future year cash flows and effective tax rate.

Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	Description of Business and Summary of Significant Accounting Policies Description of Business FTI Consulting, Inc., including its consolidated subsidiaries (collectively, the “Company,” “we,” “our” or “FTI Consulting”), is a leading global expert firm for organizations facing crisis and transformation. Individually, each of our segments and practices is staffed with experts recognized for the depth of their knowledge and a track record of making an impact. We operate through five reportable segments: Corporate Finance, Forensic and Litigation Consulting (“FLC”), Economic Consulting, Technology and Strategic Communications. The Company renamed its Corporate Finance & Restructuring segment to Corporate Finance to better align with the segment’s business activities, structure and strategy, as of December 31, 2025. The segment name change did not result in any change to the composition of the segment and has no impact on previously reported financial information. Accounting Principles Our consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). The consolidated financial statements include the accounts of FTI Consulting and all of our subsidiaries. All intercompany transactions and balances have been eliminated. Reclassifications of certain prior period amounts have been made to conform to the current period presentation. Foreign Currency Results of operations for our non-United States subsidiaries are translated from the designated functional currency to the reporting currency of the United States dollar (“USD”). Revenues and expenses are translated at average exchange rates for each month, while assets and liabilities are translated at balance sheet date exchange rates and certain equity transactions are translated at historical exchange rates. Resulting net translation adjustments are recorded as a component of stockholders’ equity in “Accumulated other comprehensive loss.” Transaction gains and losses arising from currency exchange rate fluctuations on transactions denominated in a currency other than the local functional currency are included in “Interest income and other” on the Consolidated Statements of Comprehensive Income. Such transaction gains and losses may be realized or unrealized depending upon whether the transaction settled during the period or remains outstanding at the balance sheet date. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Due to the inherent uncertainty involved in making those assumptions, actual results could differ from those estimates. Management bases its estimates on historical trends, projections, current experience and other assumptions that it believes are reasonable. Our most significant estimates relate to revenues and the assessment of the recoverability of goodwill and intangible assets. Other estimates include, but are not limited to, the realization of deferred tax assets and the fair value of acquisition-related contingent consideration. The fair values of all of our financial instruments are estimated to be equal to their carrying values as of December 31, 2025 and 2024. Concentrations of Risk We do not have a single customer that represents 10% or more of our consolidated revenues. We derive the majority of our revenues from providing professional services to clients in the United States (“U.S.”). For the year ended December 31, 2025, we derived approximately 37% of our consolidated revenues from the work of professionals who are assigned to locations outside the U.S. We believe that the geographic and industry diversity of our customer base throughout the U.S. and internationally minimizes the risk of incurring material losses due to concentrations of credit risk. Revenue Recognition Revenues are recognized when we satisfy a performance obligation by transferring services promised in a contract to a customer and in an amount that reflects the consideration that we expect to receive in exchange for those services. Performance obligations in our contracts represent distinct or separate services that we provide to our customers. If, at the outset of an arrangement, we determine that a contract with enforceable rights and obligations does not exist, revenues are deferred until all criteria for an enforceable contract are met or until consideration is received. We generate the majority of our revenues by providing consulting services to our clients. Most of our consulting service contracts are based on one of the following types of contract arrangements: •Time and expense arrangements require the client to pay us based on the number of hours worked at contractually agreed-upon rates. We recognize revenues for these contract arrangements based on hours incurred and contracted rates utilizing a right-to-invoice practical expedient because we have a right to consideration for services completed to date. When a time and expense arrangement has a not-to-exceed or “cap” amount and we expect to perform work in excess of the cap, we recognize revenues up to the cap amount specified by the client. •Fixed-fee arrangements require the client to pay a fixed-fee in exchange for a predetermined set of professional services. We recognize revenues earned to date by applying the proportional performance method. Generally, these arrangements have one performance obligation because the promises to transfer goods or services within most of our agreements are not considered to be separately identifiable. •Performance-based or contingent arrangements represent forms of variable consideration. In these arrangements, our fees are based on the attainment of contractually defined objectives with our client, such as completing a business transaction or assisting the client in achieving a specific business objective. We recognize revenues earned to date in an amount that is probable not to reverse using the expected value or most likely amount to determine the expected variable consideration and then apply the proportional performance method when the criteria for over time revenue recognition are met. Certain fees in our time and materials arrangements may be subject to approval by a third-party, such as a bankruptcy court and other regulatory agency. In such cases, we record revenues based on the amount we estimate we will be entitled to in exchange for our services and only to the extent a significant reversal of revenue is not likely to occur when the uncertainty associated with the estimate is subsequently resolved. Potential fee reductions imposed by bankruptcy courts and other regulatory agencies or negotiated with specific clients are estimated on a specific identification basis. Our estimates may vary depending on the nature of the engagement, client economics, historical experience and other appropriate factors. When there are changes in our estimates of potential fee reductions, we record such changes to revenues with a corresponding offset to our billed and unbilled accounts receivable. In our Technology segment, certain clients are billed based on the amount of data storage used or the volume of information processed. Unit-based revenues are defined as revenues billed on a per item, per page or another unit-based method and include revenues from data processing and hosting. Unit-based revenues include revenues associated with licensed software products made available to customers via a web browser (“on-demand”). On-demand revenues are charged on a unit or monthly basis and include, but are not limited to, processing and review related functions. Reimbursable expenses, including those relating to travel, out-of-pocket expenses, outside consultants and other outside service costs, are generally included in revenues, and an equivalent amount of reimbursable expenses is included in costs of services in the period in which the expense is incurred. Timing of revenue recognition often differs from the timing of billing to our customers. Generally, we transfer goods or services to a customer before the customer pays consideration or payment is due. If we have an unconditional right to invoice and receive payment for goods or services already provided, we record billed and unbilled receivables on our Consolidated Balance Sheets. Our contract terms generally include a requirement of payment within 30 days when no contingencies exist. Payment terms and conditions vary depending on the jurisdiction, market and type of service, and whether regulatory or other third-party approvals are required. At times, we may execute contracts in a form provided by customers that might include different payment terms and contracts may be negotiated at the client’s request. Direct Cost of Revenues Direct cost of revenues consists primarily of billable employee compensation and related payroll benefits, the cost of contractors assigned to revenue-generating activities and direct expenses billable to clients. Direct cost of revenues also includes expense for cloud-based computing and depreciation expense on licensed software used to host and process client information. Direct cost of revenues does not include an allocation of corporate overhead and non-billable segment costs. Share-Based Compensation Share-based compensation cost is estimated at the grant date based on the fair value of the award and is recognized as expense over the requisite service period or performance period of the award. The amount of share-based compensation expense recognized at any date must at least equal the portion of grant date value of the award that is vested at that date. The fair value of restricted share awards and restricted stock units is measured based on the closing price of the underlying stock on the date of grant. The fair value of performance stock units that contain market-based vesting conditions is measured using a Monte Carlo pricing model. The compensation cost of performance stock units with market-based vesting conditions is based on the grant date fair value and is not subsequently reversed if it is later determined that the market condition is unlikely to be met or is expected to be lower than originally anticipated. For performance stock units that contain performance-based vesting conditions, the compensation cost is adjusted each reporting period based on the probability of the awards vesting. For all of our share-based awards, we recognize forfeitures in compensation cost when they occur. Advertising Costs Advertising costs consist of marketing, advertising through print and other media, professional event sponsorship and public relations. These costs are expensed as incurred. Advertising costs totaled $26.8 million, $27.0 million and $23.0 million for the years ended December 31, 2025, 2024 and 2023, respectively, and are included in selling, general and administrative (“SG&A”) expenses on the Consolidated Statements of Comprehensive Income. Income Taxes Our income tax provision consists principally of U.S. federal, state and international income taxes. We generate income in a significant number of states located throughout the U.S. and in foreign countries in which we conduct business. Our effective income tax rate may fluctuate due to a change in the mix of earnings between higher and lower state or country tax jurisdictions and the impact of non-deductible expenses. Additionally, we record deferred tax assets and liabilities using the asset and liability method of accounting, which requires us to measure these assets and liabilities using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. We recognize a deferred tax asset if it is more likely than not (defined as a likelihood of greater than 50%) that a tax benefit will be accepted by the relevant taxing authority. The measurement of deferred tax assets and liabilities is based upon currently enacted tax rates in the applicable jurisdictions. A valuation allowance is recognized if, based on the weight of available evidence, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In evaluating our ability to recover our deferred tax assets, we consider all available positive and negative evidence, including scheduled reversals of temporary differences, projected future taxable income, tax planning strategies and recent results of operations. The historical profitability of each foreign entity is a factor in determining whether to establish or release a valuation allowance. Pre-tax operating losses on a three-year cumulative basis is considered objectively verifiable evidence and will generally outweigh a projection of future taxable income. Certain foreign subsidiaries have experienced operating losses on a three-year cumulative basis and, as a result, have recorded a valuation allowance against all or a portion of their deferred tax assets. The Inflation Reduction Act includes provisions that permit clean energy tax credits that are transferable to an unrelated third party in exchange for cash payment. When the control of the investment tax credits transfers, the acquired credits are recognized as deferred tax assets and are measured under Accounting Standards Codification Topic 740, Income Taxes. The difference between the purchase price and the tax basis of the purchased credits is recognized as deferred credits. The deferred credits are recognized in income tax expense in proportion to the reversal of the associated deferred tax asset. The amounts paid for the tax credits are presented in the “Cash paid for income taxes and tax credits, net of refunds” line in the supplemental cash flow disclosures. Cash Equivalents Cash equivalents consist of money market funds, commercial paper and certificates of deposit with maturities of three months or less at the time of purchase. Multi-Currency Notional Cash Pooling We hold a master netting arrangement with a third-party financial institution whereby certain subsidiaries participate in a notional cash pooling arrangement to manage global liquidity requirements. As part of the master netting arrangement, the participating subsidiaries may maintain either cash deposit or borrowing positions through foreign and/or local currency accounts with the bank, so long as the aggregate position of the global pool is a notionally calculated net cash deposit. Amounts in each of the accounts are unencumbered and unrestricted with respect to use. The net positive cash balance related to this pooling arrangement is included in cash and cash equivalents in the Consolidated Balance Sheets as of December 31, 2025 and 2024. Allowance for Expected Credit Losses We estimate the current-period provision for expected credit losses on a specific identification basis. Our judgments regarding a specific client’s credit risk considers factors such as the counterparty’s creditworthiness, knowledge of the specific client’s circumstances and historical collection experience for similar clients. Other factors include, but are not limited to, current economic conditions and forward-looking estimates. Our actual experience may vary from our estimates. If the financial condition of our clients were to deteriorate, resulting in their inability or unwillingness to pay our fees, we may need to record additional provisions for expected credit losses in future periods. The risk of credit losses may be mitigated to the extent that we received a retainer from some of our clients prior to performing services. We maintain an allowance for expected credit losses, which represents the estimated aggregate amount of credit risk arising from the inability or unwillingness of specific clients to pay our fees or disputes that may affect our ability to fully collect our billed accounts receivable. We record our estimate of lifetime expected credit losses concurrently with the initial recognition of the underlying receivable. Accounts receivable, net of the allowance for expected credit losses, represents the amount we expect to collect. At each reporting date, we adjust the allowance for expected credit losses to reflect our current estimate. Adjustments to the allowance for expected credit losses are recorded to SG&A expenses on the Consolidated Statements of Comprehensive Income. Our billed accounts receivables are written off when the potential for recovery is considered remote. Property and Equipment We record property and equipment, including improvements that extend useful life, at cost, while maintenance and repairs are expensed as incurred. We calculate depreciation using the straight-line method based on an estimated useful life ranging from less than one year to 15 years for furniture, equipment and software. We amortize leasehold improvements over the shorter of the estimated useful life of the asset or the lease term. We capitalize costs incurred during the application development stage of computer software developed or obtained for internal use. Capitalized software developed for internal use is classified within computer equipment and software and is amortized over the estimated useful life of the software, which ranges from less than one year to 10 years. Purchased software licenses to be sold to customers are capitalized and amortized over the license term. Notes Receivable from Employees Notes receivable from employees principally include unsecured general recourse forgivable loans which are provided to attract and retain certain of our senior employees and other professionals. Generally, all of the principal amount and accrued interest income of the forgivable loans we make to employees and other professionals will be forgiven according to the stated terms of the loan agreement, provided that the professional is providing services to the Company on the forgiveness date and upon other specified events, such as death or disability. We record accrued interest income as a reduction to operating expenses on our Consolidated Statements of Comprehensive Income. Professionals who terminate their employment or services with us prior to the end of the forgiveness period are required to repay the outstanding, unforgiven loan balance and any accrued but unforgiven interest. The unforgiven interest is recorded to “Interest income and other” on our Consolidated Statements of Comprehensive Income at the time of termination. If the termination was by the Company without “cause” or by the employee with “good reason,” or, subject to certain conditions, if the employee terminates his or her employment due to retirement or non-renewal of his or her employment agreement, the loan may be forgiven or continue to be forgivable, in whole or in part. We amortize forgivable loans straight-line over the requisite service period, which ranges from a period of one year to 10 years. The amount of expense recognized at any date must at least equal the portion of the principal forgiven on the forgiveness date. Goodwill and Intangible Assets Goodwill represents the purchase price of acquired businesses in excess of the fair market value of net assets acquired at the date of acquisition. Intangible assets may include customer relationships, trademarks and acquired software. We test our goodwill and indefinite-lived intangible assets for impairment annually as of the first day of the fourth quarter and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. On a quarterly basis, we monitor the key drivers of fair value to detect events or other changes that would warrant an interim impairment test. Important factors we consider that could trigger an interim impairment review include, but are not limited to, the following: •significant underperformance relative to expected historical or projected future operating results; •a significant change in the manner of our use of the acquired asset or the strategy for our overall business; •a significant market decline related to negative industry or economic trends; and/or •our market capitalization relative to net carrying value. We assess our goodwill for impairment at the reporting unit level. A reporting unit is an operating segment or a business one level below that operating segment if discrete financial information is available and regularly reviewed by the chief operating decision maker. Our reporting units are the same as our operating segments. Our annual goodwill impairment test may be conducted using a qualitative assessment or a quantitative assessment. Under GAAP, we have an option to bypass the qualitative assessment and perform a quantitative impairment test. We determine whether to perform a qualitative assessment first or to bypass the qualitative assessment and proceed with the quantitative goodwill impairment test for each of our reporting units based on the excess of fair value over carrying value from the most recent quantitative tests and other events or changes in circumstances that could impact the fair value of the reporting units. In the qualitative assessment, we consider various factors, events or circumstances, including macroeconomic conditions, industry and market considerations, cost factors, overall financial performance and other relevant reporting unit specific events. If, based on the qualitative assessment, we determine that it is not “more likely than not” that the fair value of a reporting unit is less than its carrying value, we do not prepare a quantitative impairment test. If we determine otherwise, we will prepare a quantitative assessment for potential goodwill impairment. In the quantitative assessment, we compare the estimated fair value of the reporting unit with the carrying amount of that reporting unit. We estimate fair value using a combination of an income approach (based on discounted cash flows) and market approaches, using appropriate weighting factors. If the fair value exceeds the carrying amount, goodwill is not impaired. However, if the carrying value exceeds the fair value of the reporting unit, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Intangible assets with finite lives are amortized over their estimated useful life and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We amortize our acquired finite-lived intangible assets on a straight-line basis over periods ranging from two to 15 years. Impairment of Long-Lived Assets We review long-lived assets such as property and equipment, operating lease assets and finite-lived intangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. These events or changes in circumstances may include a significant deterioration of operating results, changes in business plans or changes in anticipated future cash flows. If an impairment indicator is present, we evaluate recoverability of assets to be held and used by a comparison of the carrying value of the assets with future undiscounted net cash flows expected to be generated by the assets. We group assets at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows generated by other asset groups. If the total of the expected undiscounted future cash flows is less than the carrying amount of the asset group, we estimate the fair value of the asset group to determine whether an impairment loss should be recognized. Leases We determine if a contract is a leasing arrangement at inception. Operating lease assets represent our right to control the use of an identified asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized on the Consolidated Balance Sheets at the commencement date based on the present value of lease payments over the lease term. We use the incremental borrowing rate on the commencement date in determining the present value of our lease payments. We recognize operating lease expense for our operating leases on a straight-line basis over the lease term. We lease office space and equipment under non-cancelable operating leases, which may include renewal or termination options that are reasonably certain of exercise. Most leases include one or more options to renew, with renewal terms that can extend the lease term up to seven years. The exercise of lease renewal options is at our sole discretion. Certain of our lease agreements include rental payments that are adjusted periodically for inflation. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Leases with an initial term of 12 months or less are not recorded on the balance sheet and are expensed as incurred. Lease and non-lease components are accounted for together as a single lease component for operating leases associated with our office space. Billings in Excess of Services Provided Billings in excess of services provided represent amounts billed to clients, such as retainers, in advance of work being performed. Clients may make advance payments, which are held on deposit until completion of work or are applied at predetermined amounts or times. Excess payments are either applied to final billings or refunded to clients upon completion of work. Payments in excess of related accounts receivable and unbilled receivables are recorded as billings in excess of services provided within the liabilities section of the Consolidated Balance Sheets.

Description of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2025
Accounting Policies [Abstract]
Accounting Principles	Accounting Principles Our consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). The consolidated financial statements include the accounts of FTI Consulting and all of our subsidiaries. All intercompany transactions and balances have been eliminated. Reclassifications of certain prior period amounts have been made to conform to the current period presentation.
Foreign Currency	Foreign Currency Results of operations for our non-United States subsidiaries are translated from the designated functional currency to the reporting currency of the United States dollar (“USD”). Revenues and expenses are translated at average exchange rates for each month, while assets and liabilities are translated at balance sheet date exchange rates and certain equity transactions are translated at historical exchange rates. Resulting net translation adjustments are recorded as a component of stockholders’ equity in “Accumulated other comprehensive loss.” Transaction gains and losses arising from currency exchange rate fluctuations on transactions denominated in a currency other than the local functional currency are included in “Interest income and other” on the Consolidated Statements of Comprehensive Income. Such transaction gains and losses may be realized or unrealized depending upon whether the transaction settled during the period or remains outstanding at the balance sheet date.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Due to the inherent uncertainty involved in making those assumptions, actual results could differ from those estimates. Management bases its estimates on historical trends, projections, current experience and other assumptions that it believes are reasonable. Our most significant estimates relate to revenues and the assessment of the recoverability of goodwill and intangible assets. Other estimates include, but are not limited to, the realization of deferred tax assets and the fair value of acquisition-related contingent consideration. The fair values of all of our financial instruments are estimated to be equal to their carrying values as of December 31, 2025 and 2024.
Concentrations of Risk	Concentrations of Risk We do not have a single customer that represents 10% or more of our consolidated revenues. We derive the majority of our revenues from providing professional services to clients in the United States (“U.S.”). For the year ended December 31, 2025, we derived approximately 37% of our consolidated revenues from the work of professionals who are assigned to locations outside the U.S. We believe that the geographic and industry diversity of our customer base throughout the U.S. and internationally minimizes the risk of incurring material losses due to concentrations of credit risk.
Revenue Recognition	Revenue Recognition Revenues are recognized when we satisfy a performance obligation by transferring services promised in a contract to a customer and in an amount that reflects the consideration that we expect to receive in exchange for those services. Performance obligations in our contracts represent distinct or separate services that we provide to our customers. If, at the outset of an arrangement, we determine that a contract with enforceable rights and obligations does not exist, revenues are deferred until all criteria for an enforceable contract are met or until consideration is received. We generate the majority of our revenues by providing consulting services to our clients. Most of our consulting service contracts are based on one of the following types of contract arrangements: •Time and expense arrangements require the client to pay us based on the number of hours worked at contractually agreed-upon rates. We recognize revenues for these contract arrangements based on hours incurred and contracted rates utilizing a right-to-invoice practical expedient because we have a right to consideration for services completed to date. When a time and expense arrangement has a not-to-exceed or “cap” amount and we expect to perform work in excess of the cap, we recognize revenues up to the cap amount specified by the client. •Fixed-fee arrangements require the client to pay a fixed-fee in exchange for a predetermined set of professional services. We recognize revenues earned to date by applying the proportional performance method. Generally, these arrangements have one performance obligation because the promises to transfer goods or services within most of our agreements are not considered to be separately identifiable. •Performance-based or contingent arrangements represent forms of variable consideration. In these arrangements, our fees are based on the attainment of contractually defined objectives with our client, such as completing a business transaction or assisting the client in achieving a specific business objective. We recognize revenues earned to date in an amount that is probable not to reverse using the expected value or most likely amount to determine the expected variable consideration and then apply the proportional performance method when the criteria for over time revenue recognition are met. Certain fees in our time and materials arrangements may be subject to approval by a third-party, such as a bankruptcy court and other regulatory agency. In such cases, we record revenues based on the amount we estimate we will be entitled to in exchange for our services and only to the extent a significant reversal of revenue is not likely to occur when the uncertainty associated with the estimate is subsequently resolved. Potential fee reductions imposed by bankruptcy courts and other regulatory agencies or negotiated with specific clients are estimated on a specific identification basis. Our estimates may vary depending on the nature of the engagement, client economics, historical experience and other appropriate factors. When there are changes in our estimates of potential fee reductions, we record such changes to revenues with a corresponding offset to our billed and unbilled accounts receivable. In our Technology segment, certain clients are billed based on the amount of data storage used or the volume of information processed. Unit-based revenues are defined as revenues billed on a per item, per page or another unit-based method and include revenues from data processing and hosting. Unit-based revenues include revenues associated with licensed software products made available to customers via a web browser (“on-demand”). On-demand revenues are charged on a unit or monthly basis and include, but are not limited to, processing and review related functions. Reimbursable expenses, including those relating to travel, out-of-pocket expenses, outside consultants and other outside service costs, are generally included in revenues, and an equivalent amount of reimbursable expenses is included in costs of services in the period in which the expense is incurred. Timing of revenue recognition often differs from the timing of billing to our customers. Generally, we transfer goods or services to a customer before the customer pays consideration or payment is due. If we have an unconditional right to invoice and receive payment for goods or services already provided, we record billed and unbilled receivables on our Consolidated Balance Sheets. Our contract terms generally include a requirement of payment within 30 days when no contingencies exist. Payment terms and conditions vary depending on the jurisdiction, market and type of service, and whether regulatory or other third-party approvals are required. At times, we may execute contracts in a form provided by customers that might include different payment terms and contracts may be negotiated at the client’s request. Direct Cost of Revenues Direct cost of revenues consists primarily of billable employee compensation and related payroll benefits, the cost of contractors assigned to revenue-generating activities and direct expenses billable to clients. Direct cost of revenues also includes expense for cloud-based computing and depreciation expense on licensed software used to host and process client information. Direct cost of revenues does not include an allocation of corporate overhead and non-billable segment costs.
Share-Based Compensation	Share-Based Compensation Share-based compensation cost is estimated at the grant date based on the fair value of the award and is recognized as expense over the requisite service period or performance period of the award. The amount of share-based compensation expense recognized at any date must at least equal the portion of grant date value of the award that is vested at that date. The fair value of restricted share awards and restricted stock units is measured based on the closing price of the underlying stock on the date of grant. The fair value of performance stock units that contain market-based vesting conditions is measured using a Monte Carlo pricing model. The compensation cost of performance stock units with market-based vesting conditions is based on the grant date fair value and is not subsequently reversed if it is later determined that the market condition is unlikely to be met or is expected to be lower than originally anticipated. For performance stock units that contain performance-based vesting conditions, the compensation cost is adjusted each reporting period based on the probability of the awards vesting. For all of our share-based awards, we recognize forfeitures in compensation cost when they occur.
Advertising Costs	Advertising Costs Advertising costs consist of marketing, advertising through print and other media, professional event sponsorship and public relations. These costs are expensed as incurred.
Income Taxes	Income Taxes Our income tax provision consists principally of U.S. federal, state and international income taxes. We generate income in a significant number of states located throughout the U.S. and in foreign countries in which we conduct business. Our effective income tax rate may fluctuate due to a change in the mix of earnings between higher and lower state or country tax jurisdictions and the impact of non-deductible expenses. Additionally, we record deferred tax assets and liabilities using the asset and liability method of accounting, which requires us to measure these assets and liabilities using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. We recognize a deferred tax asset if it is more likely than not (defined as a likelihood of greater than 50%) that a tax benefit will be accepted by the relevant taxing authority. The measurement of deferred tax assets and liabilities is based upon currently enacted tax rates in the applicable jurisdictions. A valuation allowance is recognized if, based on the weight of available evidence, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In evaluating our ability to recover our deferred tax assets, we consider all available positive and negative evidence, including scheduled reversals of temporary differences, projected future taxable income, tax planning strategies and recent results of operations. The historical profitability of each foreign entity is a factor in determining whether to establish or release a valuation allowance. Pre-tax operating losses on a three-year cumulative basis is considered objectively verifiable evidence and will generally outweigh a projection of future taxable income. Certain foreign subsidiaries have experienced operating losses on a three-year cumulative basis and, as a result, have recorded a valuation allowance against all or a portion of their deferred tax assets. The Inflation Reduction Act includes provisions that permit clean energy tax credits that are transferable to an unrelated third party in exchange for cash payment. When the control of the investment tax credits transfers, the acquired credits are recognized as deferred tax assets and are measured under Accounting Standards Codification Topic 740, Income Taxes. The difference between the purchase price and the tax basis of the purchased credits is recognized as deferred credits. The deferred credits are recognized in income tax expense in proportion to the reversal of the associated deferred tax asset. The amounts paid for the tax credits are presented in the “Cash paid for income taxes and tax credits, net of refunds” line in the supplemental cash flow disclosures.
Cash Equivalents	Cash Equivalents Cash equivalents consist of money market funds, commercial paper and certificates of deposit with maturities of three months or less at the time of purchase.
Multi-Currency Notional Cash Pooling	Multi-Currency Notional Cash Pooling We hold a master netting arrangement with a third-party financial institution whereby certain subsidiaries participate in a notional cash pooling arrangement to manage global liquidity requirements. As part of the master netting arrangement, the participating subsidiaries may maintain either cash deposit or borrowing positions through foreign and/or local currency accounts with the bank, so long as the aggregate position of the global pool is a notionally calculated net cash deposit. Amounts in each of the accounts are unencumbered and unrestricted with respect to use. The net positive cash balance related to this pooling arrangement is included in cash and cash equivalents in the Consolidated Balance Sheets as of December 31, 2025 and 2024.
Allowance for Expected Credit Losses	Allowance for Expected Credit Losses We estimate the current-period provision for expected credit losses on a specific identification basis. Our judgments regarding a specific client’s credit risk considers factors such as the counterparty’s creditworthiness, knowledge of the specific client’s circumstances and historical collection experience for similar clients. Other factors include, but are not limited to, current economic conditions and forward-looking estimates. Our actual experience may vary from our estimates. If the financial condition of our clients were to deteriorate, resulting in their inability or unwillingness to pay our fees, we may need to record additional provisions for expected credit losses in future periods. The risk of credit losses may be mitigated to the extent that we received a retainer from some of our clients prior to performing services. We maintain an allowance for expected credit losses, which represents the estimated aggregate amount of credit risk arising from the inability or unwillingness of specific clients to pay our fees or disputes that may affect our ability to fully collect our billed accounts receivable. We record our estimate of lifetime expected credit losses concurrently with the initial recognition of the underlying receivable. Accounts receivable, net of the allowance for expected credit losses, represents the amount we expect to collect. At each reporting date, we adjust the allowance for expected credit losses to reflect our current estimate. Adjustments to the allowance for expected credit losses are recorded to SG&A expenses on the Consolidated Statements of Comprehensive Income. Our billed accounts receivables are written off when the potential for recovery is considered remote.
Property and Equipment	Property and Equipment We record property and equipment, including improvements that extend useful life, at cost, while maintenance and repairs are expensed as incurred. We calculate depreciation using the straight-line method based on an estimated useful life ranging from less than one year to 15 years for furniture, equipment and software. We amortize leasehold improvements over the shorter of the estimated useful life of the asset or the lease term. We capitalize costs incurred during the application development stage of computer software developed or obtained for internal use. Capitalized software developed for internal use is classified within computer equipment and software and is amortized over the estimated useful life of the software, which ranges from less than one year to 10 years. Purchased software licenses to be sold to customers are capitalized and amortized over the license term.
Notes Receivable from Employees	Notes Receivable from Employees Notes receivable from employees principally include unsecured general recourse forgivable loans which are provided to attract and retain certain of our senior employees and other professionals. Generally, all of the principal amount and accrued interest income of the forgivable loans we make to employees and other professionals will be forgiven according to the stated terms of the loan agreement, provided that the professional is providing services to the Company on the forgiveness date and upon other specified events, such as death or disability. We record accrued interest income as a reduction to operating expenses on our Consolidated Statements of Comprehensive Income. Professionals who terminate their employment or services with us prior to the end of the forgiveness period are required to repay the outstanding, unforgiven loan balance and any accrued but unforgiven interest. The unforgiven interest is recorded to “Interest income and other” on our Consolidated Statements of Comprehensive Income at the time of termination. If the termination was by the Company without “cause” or by the employee with “good reason,” or, subject to certain conditions, if the employee terminates his or her employment due to retirement or non-renewal of his or her employment agreement, the loan may be forgiven or continue to be forgivable, in whole or in part. We amortize forgivable loans straight-line over the requisite service period, which ranges from a period of one year to 10 years. The amount of expense recognized at any date must at least equal the portion of the principal forgiven on the forgiveness date.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the purchase price of acquired businesses in excess of the fair market value of net assets acquired at the date of acquisition. Intangible assets may include customer relationships, trademarks and acquired software. We test our goodwill and indefinite-lived intangible assets for impairment annually as of the first day of the fourth quarter and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. On a quarterly basis, we monitor the key drivers of fair value to detect events or other changes that would warrant an interim impairment test. Important factors we consider that could trigger an interim impairment review include, but are not limited to, the following: •significant underperformance relative to expected historical or projected future operating results; •a significant change in the manner of our use of the acquired asset or the strategy for our overall business; •a significant market decline related to negative industry or economic trends; and/or •our market capitalization relative to net carrying value. We assess our goodwill for impairment at the reporting unit level. A reporting unit is an operating segment or a business one level below that operating segment if discrete financial information is available and regularly reviewed by the chief operating decision maker. Our reporting units are the same as our operating segments. Our annual goodwill impairment test may be conducted using a qualitative assessment or a quantitative assessment. Under GAAP, we have an option to bypass the qualitative assessment and perform a quantitative impairment test. We determine whether to perform a qualitative assessment first or to bypass the qualitative assessment and proceed with the quantitative goodwill impairment test for each of our reporting units based on the excess of fair value over carrying value from the most recent quantitative tests and other events or changes in circumstances that could impact the fair value of the reporting units. In the qualitative assessment, we consider various factors, events or circumstances, including macroeconomic conditions, industry and market considerations, cost factors, overall financial performance and other relevant reporting unit specific events. If, based on the qualitative assessment, we determine that it is not “more likely than not” that the fair value of a reporting unit is less than its carrying value, we do not prepare a quantitative impairment test. If we determine otherwise, we will prepare a quantitative assessment for potential goodwill impairment. In the quantitative assessment, we compare the estimated fair value of the reporting unit with the carrying amount of that reporting unit. We estimate fair value using a combination of an income approach (based on discounted cash flows) and market approaches, using appropriate weighting factors. If the fair value exceeds the carrying amount, goodwill is not impaired. However, if the carrying value exceeds the fair value of the reporting unit, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Intangible assets with finite lives are amortized over their estimated useful life and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We amortize our acquired finite-lived intangible assets on a straight-line basis over periods ranging from two to 15 years.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets We review long-lived assets such as property and equipment, operating lease assets and finite-lived intangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. These events or changes in circumstances may include a significant deterioration of operating results, changes in business plans or changes in anticipated future cash flows. If an impairment indicator is present, we evaluate recoverability of assets to be held and used by a comparison of the carrying value of the assets with future undiscounted net cash flows expected to be generated by the assets. We group assets at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows generated by other asset groups. If the total of the expected undiscounted future cash flows is less than the carrying amount of the asset group, we estimate the fair value of the asset group to determine whether an impairment loss should be recognized.
Leases	Leases We determine if a contract is a leasing arrangement at inception. Operating lease assets represent our right to control the use of an identified asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized on the Consolidated Balance Sheets at the commencement date based on the present value of lease payments over the lease term. We use the incremental borrowing rate on the commencement date in determining the present value of our lease payments. We recognize operating lease expense for our operating leases on a straight-line basis over the lease term. We lease office space and equipment under non-cancelable operating leases, which may include renewal or termination options that are reasonably certain of exercise. Most leases include one or more options to renew, with renewal terms that can extend the lease term up to seven years. The exercise of lease renewal options is at our sole discretion. Certain of our lease agreements include rental payments that are adjusted periodically for inflation. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Leases with an initial term of 12 months or less are not recorded on the balance sheet and are expensed as incurred. Lease and non-lease components are accounted for together as a single lease component for operating leases associated with our office space.
Billings in Excess of Services Provided	Billings in Excess of Services Provided Billings in excess of services provided represent amounts billed to clients, such as retainers, in advance of work being performed. Clients may make advance payments, which are held on deposit until completion of work or are applied at predetermined amounts or times. Excess payments are either applied to final billings or refunded to clients upon completion of work. Payments in excess of related accounts receivable and unbilled receivables are recorded as billings in excess of services provided within the liabilities section of the Consolidated Balance Sheets.
Recently Adopted Accounting Standards and Accounting Standards Not Yet Adopted	Recently Adopted Accounting Standards In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands annual disclosures in an entity’s income tax rate reconciliation table and requires annual disclosures regarding cash taxes paid both in the U.S. (federal, state and local) and foreign jurisdictions. We adopted ASU 2023-09 on a prospective basis, beginning with the year ended December 31, 2025. See Note 16, “Income Taxes” for disclosures required under ASU 2023-09. Accounting Standards Not Yet Adopted In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires additional, disaggregated disclosure around certain income statement expense line items. The amendments in this ASU are effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027, although early adoption is permitted. The Company is in the process of evaluating the impact of this new guidance on its consolidated financial statements. In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which modernizes the accounting for internal-use software costs by increasing the operability of the recognition guidance to reflect neutrality toward different methods of software development. The amendments in this ASU are effective for annual and interim periods beginning after December 15, 2027 and can be applied prospectively, retrospectively, or with a modified transition approach. Early adoption is permitted. The Company is in the process of evaluating the impact of this new guidance on its consolidated financial statements.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We are subject to legal actions arising in the ordinary course of business. In management’s opinion, we believe we have adequate legal defenses and/or insurance coverage with respect to the eventuality of such actions. We are not aware of any asserted or unasserted legal proceedings or claims that we believe would have a material adverse effect on our financial condition or our results of operations. During the year ended December 31, 2025, the Company recognized gain contingencies at the conclusion of certain legal actions. These amounts are included as a gain in SG&A expenses on our Consolidated Statements of Comprehensive Income. As of December 31, 2025 and 2024, we were contingently liable under bank guarantees issued in favor of third parties that totaled $17.5 million and $10.9 million, respectively. These bank guarantees primarily support bid and performance obligations and operating leases for office space. The amounts are guaranteed under guarantee facilities totaling $32.5 million and $42.7 million as of December 31, 2025 and 2024, respectively. We had $15.0 million and $31.8 million available under the guarantee facilities as of December 31, 2025 and 2024, respectively. These bank guarantees are issued separately from our Credit Facility and, as a result, do not affect available borrowing capacity under our Credit Facility. We entered into a material lease agreement for our new office space in London, England during the year ended December 31, 2025. See Note 14, “Leases” for additional information about the terms of the Leases.

Share-Based Compensation Expense

The table below reflects the total share-based compensation expense recognized in our Consolidated Statements of Comprehensive Income for the years ended December 31, 2025, 2024 and 2023:


	Year Ended December 31,

Income Statement Classification	2025		2024		2023
Direct cost of revenues	$	26,821	$	22,179	$	19,067

Total	$	41,705	$	42,181	$	36,272

Restricted Share Awards

The following table summarizes our restricted share awards activity during the year ended December 31, 2025.

As of December 31, 2025, there was $61.7 million of unrecognized compensation cost related to unvested restricted share awards. That cost is expected to be recognized ratably over a weighted average period of 3.8 years. The total fair value of restricted share awards that vested during the years ended December 31, 2025, 2024 and 2023 was $26.8 million, $28.1 million and $29.0 million, respectively.

Restricted Stock Units

The following table summarizes our restricted stock units activity during the year ended December 31, 2025.


	Shares	Weighted Average Grant Date Fair Value
Restricted stock units outstanding at December 31, 2024	489	$	130.79
Restricted stock units granted	115	$	166.84
Restricted stock units released	(104)	$	91.92
Restricted stock units forfeited	(18)	$	179.09
Restricted stock units outstanding at December 31, 2025	482	$	146.01

As of December 31, 2025, there was $38.2 million of unrecognized compensation cost related to unvested restricted stock units. That cost is expected to be recognized ratably over a weighted average period of 3.8 years. The total fair value of restricted stock units released for the years ended December 31, 2025, 2024 and 2023 was $17.9 million, $8.7 million and $6.6 million, respectively.

Performance Stock Units

Performance stock units represent common stock potentially issuable in the future, subject to achievement of either market or performance conditions. Our current outstanding performance stock units that are subject to market conditions vest based on the adjusted total shareholder return of the Company as compared to the adjusted total shareholder return of the Standard & Poor’s 500 Index over the applicable performance period. Our current outstanding performance stock units that are subject to performance conditions vest based on Adjusted EBITDA metrics over the applicable performance period. The vesting and payout range for all of our performance stock units is typically between 0% and up to 150% of the target number of shares granted at the end of a two- or three-year performance period.

The following table summarizes our performance stock units activity during the year ended December 31, 2025.


	Shares	Weighted Average Grant Date Fair Value
Performance stock units outstanding at December 31, 2024	208	$	190.14
Performance stock units granted (1)	106	$	158.26
Performance stock units released	(59)	$	164.88
Performance stock units forfeited (2)	(44)	$	184.44
Performance stock units outstanding at December 31, 2025	211	$	182.42

(1) Performance stock units granted are presented at the maximum potential payout percentage of 150% of target shares granted.

As of December 31, 2025, there was $6.2 million of unrecognized compensation cost related to unvested performance stock units. That cost is expected to be recognized ratably over a weighted average period of 0.8 years. The total fair value of performance stock units released during the years ended December 31, 2025, 2024 and 2023 was $11.1 million, $15.2 million and $11.7 million, respectively.

The weighted average grant date fair value per share of restricted share awards, restricted stock units and performance stock units awarded during the years ended December 31, 2025, 2024 and 2023 was $163.83, $211.79 and $187.85, respectively. The fair value of our restricted share awards, restricted stock units and performance stock units that are subject to performance conditions is determined based on the closing market price per share of our common stock on the grant date. The fair value of our performance stock units subject to market conditions is calculated using a Monte Carlo pricing model as of the grant date.

Stock Options

We did not grant any stock options during the years ended December 31, 2025, 2024 and 2023. Historically, we used the Black-Scholes option-pricing model to determine the fair value of our stock option grants.

The following table summarizes our stock option activity during the year ended December 31, 2025.


	Options	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in Years)	Aggregate Intrinsic Value
Stock options outstanding at December 31, 2024	60	$	37.93

Stock options exercised	(38)	$	36.53

Stock options outstanding and exercisable at December 31, 2025	22	$	40.36	1.2	$	2,876

Cash received from option exercises for the years ended December 31, 2025, 2024 and 2023 was $1.4 million, $10.9 million and $1.3 million, respectively. The tax benefit realized from stock options exercised was immaterial for each of the years ended December 31, 2025, 2024 and 2023.

The intrinsic value of stock options exercised is the amount by which the market value of our common stock on the exercise date exceeds the exercise price. The total intrinsic value of stock options exercised for the years ended December 31, 2025, 2024 and 2023 was $4.9 million, $52.0 million and $6.0 million, respectively.

As of December 31, 2025, there was no unrecognized compensation cost related to stock options.

On November 21, 2025, we entered into a material lease agreement to accept possession of three leases (the “Leases”) for our new office space in London, England. We expect to accept possession of the premises on or about September 25, 2027, subject to the satisfaction of certain conditions. The Leases will have a fixed term of 15 years, subject to a break option allowing the tenant, which is a wholly-owned subsidiary of the Company, to terminate the Leases at the end of the 10th year. At the end of the initial 15-year term, the tenant has a one-time contractual right to renew each of the Leases for a term of either five years or ten years. Fixed rental payments under the Leases are scheduled to commence in February 2028, payable in quarterly installments, and will aggregate to approximately $115.0 million. The Leases are not included within “Operating lease assets” and “Operating lease liabilities” on the Consolidated Balance Sheets as of December 31, 2025, as the Company does not yet have the right to use the premises.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	We operate our segments and their practices through FTI Consulting and its subsidiaries in 32 countries with different business, client, and geographic cybersecurity risk profiles. We aim to proactively identify and assess our vulnerability to cybersecurity threats and actual cybersecurity incidents on an ongoing basis at both the enterprise level, as well as at a more operational level, differentiating unique risks related to our segments, practices, clients, employees, and the locations in which business is conducted. Our Information Technology Group (“ITG”) helps monitor and analyze cybersecurity incidents and risks and our progress mitigating and resolving such threats. This information is regularly discussed with our outside directors and executive management. Approach and Integration Cybersecurity risk is integrated and managed as part of our broader enterprise risk management program under the direction of our Vice President – Chief Risk and Compliance Officer – who works closely with our Chief Information Officer and others, including the Head of our Cybersecurity & Privacy division to help identify, review, assess and address cybersecurity and other security risks. Our Chief Risk and Compliance Officer, Chief Information Officer and the Head of our Cybersecurity & Privacy division are members of the Company’s cybersecurity response team (the “Cyber Response Team”). The Cyber Response Team’s responsibilities include maintaining a Cybersecurity Incident Response Plan, which sets out a path for how cyber threats and incidents are identified and escalated up to and including the Board of Directors and other leadership, when appropriate. Direct threats are escalated promptly to the appropriate team, following a path that considers both the nature of the threat, the level of risk, and the degree to which it has been substantiated. Indirect threats, such as third-party incidents, are escalated through the ITG to the appropriate corporate functions, as the situation warrants. Third-Party Engagement and Oversight Where appropriate, we engage third-party vendors to provide cybersecurity-related services, including security monitoring, risk assessments, penetration testing, audit support and incident response services. Vendors are selected through due diligence processes appropriate to the nature of the services provided, and we enter into written agreements that include provisions addressing data security, confidentiality, privacy and incident notification. We conduct vendor oversight activities based on the nature of the services and associated risks, which may include performance discussions, issue management and remediation follow-up, as appropriate. Our Vendor Code of Conduct (“VCC”) establishes expectations related to ethical conduct and data protection. As part of applicable vendor onboarding processes, vendors are required to acknowledge and agree to comply with the VCC or to provide an alternative code of conduct that demonstrates comparable standards. For vendor engagements involving access to information systems, confidential information or physical security considerations, appropriate cross-functional stakeholders participate in risk and compliance reviews during the procurement and contract review process prior to engagement. Our contracts for such vendors include provisions designed to safeguard company and client information and to define responsibilities in the event of a security incident. Incident Response Plan and Training In the event of the detection of a potentially significant cybersecurity incident or threat, an escalation of cybersecurity threat, or changes with respect to a current incident, the Company has processes in place to notify relevant employees who assist in the response, as well as third-party vendors. Our ITG and management, in consultation with the Company’s outside legal counsel and accountants, will assess materiality, informed by ongoing discussions about what criteria would constitute potential materiality considerations. The Audit Committee and necessary directors will be informed of all material events. To educate our management, employees, and consultants, and help mitigate the risk of human failure in exposing our Information Technology systems to cybersecurity threats from bad actors, our management, employees, and consultants are required to complete on-line cybersecurity training annually. We also provide regular reminders to employees regarding suspicious emails or other communications and conduct periodic phishing simulations and remedial spot testing and training to reinforce recognition and response techniques. In 2025, we continued to review and refine our incident response procedures. We conducted technical tabletop exercises, simulating cybersecurity events and appropriate responses, with the senior leadership team of FTI Consulting, including an executive officer and an outside director, and provided regular quarterly updates to the Board of Directors on ongoing efforts to strengthen our security posture. We continue to communicate with the broader executive incident response team on updates to our incident response posture and any simulation training conducted on a periodic basis. The expanded incident response briefing schedule is also included in the annual Board of Directors briefing, and directors and certain officers of the Company have been and will continue to be given the opportunity to participate in simulation training. In addition, our outside directors are encouraged to attend continuing education relating to cybersecurity. Materiality of Risks We are subject to and routinely face cyber-based attacks and attempts by hackers and similar unauthorized users seeking to gain access to or corrupt our information technology systems. Since the beginning of the last fiscal year, we have not identified risks from known cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected us, including our business strategy, results of operations, or financial condition, or that we believe are reasonably likely to have such an effect over the long term. However, there can be no assurance that we will be able to successfully mitigate the negative impacts of cybersecurity threats in the future. Accordingly, we continue to prioritize our cybersecurity risk management despite the lack of identified material impacts to date.

The Head of our Cybersecurity and Privacy division has been with FTI since 2007 and has extensive experience in the cybersecurity field. The members of Cybersecurity & Privacy division have experience and education in cybersecurity, risk management, data assurance, and compliance. Among them they hold various certifications in information systems security and privacy. The practices and activities of our cybersecurity and information technology teams align with internationally accepted management frameworks. Furthermore, we offer cybersecurity consulting as a service to clients. Our client-facing cybersecurity and information security experts periodically advise our cybersecurity and information technology teams regarding best practices. In addition, from time-to-time, they address our executives, directors, and other segment or regional leaders regarding complex issues faced by other companies that arise from data-security-related challenges. Among other things, they discuss new and evolving types and levels of threats and attacks, hacking and ransomware, foreign actors, risks driven by new and evolving technologies, including artificial intelligence, potential damages, and liability, and technological and other solutions potentially available to mitigate such risks, as well as other company responses. The existence of this team within FTI aids in our ability to have current incident and threat intelligence that we can use to bolster our own security posture and defenses. Our cybersecurity practice also provides us with supplemental incident response investigation services in partnership with independent, external consultants, as needed and as appropriate. For additional information on the risks we face related to cyber and information security threats, please see the related risk factor in Item 1A. Risk Factors.

Revenues	12 Months Ended
Revenues	Dec. 31, 2025
Revenue from Contract with Customer [Abstract]
Revenues	Revenues We generate the majority of our revenues by providing consulting services to our clients. See Note 1, “Description of Business and Summary of Significant Accounting Policies” for additional information on our accounting policies for revenues. Revenues are recognized when we satisfy a performance obligation by transferring services promised in a contract to a customer and in an amount that reflects the consideration that we expect to receive in exchange for those services. Performance obligations in our contracts represent distinct or separate services that we provide to our customers. We estimate that approximately 76% of our revenues recognized during the year ended December 31, 2025 were generated from time and expense contract arrangements. If, at the outset of an arrangement, we determine that a contract with enforceable rights and obligations does not exist, revenues are deferred until all criteria for an enforceable contract are met. Revenues recognized during the current period may include revenues from performance obligations satisfied or partially satisfied in prior periods. This primarily occurs when the estimated transaction price has changed based on our current probability assessment over whether the agreed-upon outcome for our performance-based and contingent arrangements will be achieved. The aggregate amount of revenues recognized related to a change in the transaction price in the current period, which related to performance obligations satisfied or partially satisfied in a prior period, was $26.0 million, $20.0 million and $11.7 million for the years ended December 31, 2025, 2024 and 2023, respectively. Unfulfilled performance obligations primarily consist of fees not yet recognized on certain fixed-fee arrangements and performance-based and contingent arrangements. As of December 31, 2025 and 2024, the aggregate amount of the remaining contract transaction price allocated to unfulfilled performance obligations was $27.3 million and $25.5 million, respectively. We expect to recognize the majority of the related revenues over the next 12 months. We elected to utilize the optional exemption to exclude from this disclosure fixed-fee and performance-based and contingent arrangements with an original expected duration of one year or less and to exclude our time and expense arrangements for which revenues are recognized using the right-to-invoice practical expedient. Contract assets are defined as assets for which we have recorded revenues but are not yet entitled to receive our fees because certain events, such as completion of the measurement period or client approval, must occur. The contract asset balance was immaterial as of December 31, 2025 and 2024, respectively. Contract liabilities are defined as liabilities incurred when we have received consideration but have not yet performed the agreed-upon services. This may occur when clients pay fees before work begins. The contract liability balance was immaterial as of December 31, 2025 and 2024, respectively.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Debt	12 Months Ended
Debt	Dec. 31, 2025
Debt Disclosure [Abstract]
Debt	Debt Long-term debt outstanding under our senior unsecured bank revolving credit facility (“Credit Facility”) was $365.0 million and there was no current portion as of December 31, 2025. The Company classified the borrowings under the Credit Facility as long-term debt in the accompanying Consolidated Balance Sheets, as we have the intent and unilateral ability to refinance any borrowings on a continuous basis through the maturity of the Credit Facility on November 21, 2027. There was no debt outstanding as of December 31, 2024. Our second amended and restated credit agreement governing our Credit Facility has a revolving line of credit limit of $900.0 million and a maximum incremental facility of $300.0 million, subject to certain conditions. The Credit Facility was originally guaranteed by substantially all of our wholly owned domestic subsidiaries and was originally secured by a first priority security interest in substantially all of the assets of FTI Consulting and such domestic subsidiaries. In October 2024, the Company’s credit rating was upgraded to investment grade by S&P Global. The upgraded rating triggered a Ratings Collateral Release Date under, and as defined in, the Credit Facility. Upon the occurrence of the Ratings Collateral Release Date, the security interests and liens previously granted to the lenders were automatically terminated and released, and the Credit Facility is now unsecured, with only unsecured guarantees being provided by substantially all of our wholly owned domestic subsidiaries. Borrowings under the Credit Facility bear interest at a rate equal to, in the case of: (i) USD, at our option, Adjusted Term Secured Overnight Financing Rate (“SOFR”) or Adjusted Daily Simple SOFR, (ii) euros, Euro Interbank Offered Rate, (iii) British pounds, Sterling Overnight Index Average Reference Rate, (iv) Australian dollars, Bank Bill Swap Reference Bid Rate, (v) Canadian dollars, Canadian Dollar Offered Rate, (vi) Swiss francs, Swiss Average Rate Overnight, and (vii) Japanese yen, Tokyo Interbank Offered Rate, in each case, plus an applicable margin that will fluctuate between 1.25% per annum and 2.00% per annum based upon the Company’s Consolidated Total Net Leverage Ratio (as defined in the Credit Facility) at such time or, in the case of USD borrowings, an alternative base rate plus an applicable margin that will fluctuate between 0.25% per annum and 1.00% per annum based upon the Company’s Consolidated Total Net Leverage Ratio at such time. The alternative base rate is a fluctuating rate per annum equal to the highest of (1) the Federal Funds rate plus the sum of 50 basis points, (2) the rate of interest in effect for such day as the prime rate announced by Bank of America, and (3) the one-month Term SOFR plus the Term SOFR Adjustment plus 100 basis points. Under the Credit Facility, we are required to pay a commitment fee rate that fluctuates between 0.20% and 0.35% per annum and a letter of credit fee rate that fluctuates between 1.25% and 2.00% per annum, in each case, based upon the Company’s Consolidated Total Net Leverage Ratio.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

New Accounting Standards	Dec. 31, 2025
Accounting Changes and Error Corrections [Abstract]
New Accounting Standards	New Accounting Standards Recently Adopted Accounting Standards In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands annual disclosures in an entity’s income tax rate reconciliation table and requires annual disclosures regarding cash taxes paid both in the U.S. (federal, state and local) and foreign jurisdictions. We adopted ASU 2023-09 on a prospective basis, beginning with the year ended December 31, 2025. See Note 16, “Income Taxes” for disclosures required under ASU 2023-09. Accounting Standards Not Yet Adopted In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires additional, disaggregated disclosure around certain income statement expense line items. The amendments in this ASU are effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027, although early adoption is permitted. The Company is in the process of evaluating the impact of this new guidance on its consolidated financial statements. In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which modernizes the accounting for internal-use software costs by increasing the operability of the recognition guidance to reflect neutrality toward different methods of software development. The amendments in this ASU are effective for annual and interim periods beginning after December 15, 2027 and can be applied prospectively, retrospectively, or with a modified transition approach. Early adoption is permitted. The Company is in the process of evaluating the impact of this new guidance on its consolidated financial statements.

- Definition

The entire disclosure for change in accounting principle. Includes, but is not limited to, nature, reason, and method of adopting amendment to accounting standards or other change in accounting principle.

Segment Reporting [Abstract]

Segment Reporting

We manage our business in five reportable segments: Corporate Finance, FLC, Economic Consulting, Technology and Strategic Communications.

Our Corporate Finance segment focuses on the strategic, operational, financial, transactional and capital needs of our clients around the world. Our clients include companies, boards of directors, investors, private equity sponsors, lenders, and other financing sources and creditor groups, governments and other interested parties. We deliver a wide range of services centered around three core offerings: Transactions, Transformation and Turnaround & Restructuring.

Our FLC segment provides law firms, companies, boards of directors, government entities, private equity firms and other interested parties with a multidisciplinary and independent range of services across risk & investigations and disputes, supported by our data & analytics technology-enabled solutions, with a focus on highly regulated industries. Our services are centered around five core offerings: Construction, Projects & Assets and Environmental Solutions, Data & Analytics, Dispute Advisory Services, Healthcare Risk Management & Advisory and Risk & Investigations, which includes our cybersecurity and financial services-related offerings.

Our Economic Consulting segment, including subsidiary Compass Lexecon LLC, provides law firms, companies, government entities and other interested parties with analyses of complex economic issues for use in international arbitration, legal and regulatory proceedings and strategic decision making and public policy debates around the world. We deliver a wide range of services centered around three core offerings: Antitrust & Competition Economics, Financial Economics and International Arbitration.

Our Technology segment provides companies, law firms, private equity firms and government entities with a comprehensive global portfolio of digital insights and risk management, artificial intelligence (“AI”) and data services. Our professionals help organizations better address risk as the growing volume and variety of enterprise and emerging data intersects with legal, regulatory and compliance needs. We deliver a wide range of expert and AI-powered solutions driven by five core client needs: Blockchain & Digital Assets, Information Governance, Privacy & Security, Investigations, Litigation, and M&A, Antitrust and Competition.

Our Strategic Communications segment develops and executes communications strategies to help management teams, boards of directors, law firms, governments and regulators manage change and mitigate risk surrounding transformational and disruptive events, including crises, transactions, investigations, disputes, regulation and legislation. We deliver a wide range of services centered around three core offerings: Corporate Reputation, Financial Communications and Public Affairs.

We have considered information that is regularly provided to our Chief Executive Officer, who is our chief operating decision maker (“CODM”), for our segment reporting disclosure. Our CODM assesses the performance and allocates resources to each segment based on revenues and multiple measures of segment profit, including gross profit, which is the measure closest to GAAP reporting principles. Gross profit is defined as revenues less direct costs of revenues. Our CODM uses gross profit (i) to evaluate reportable segment performance against budgets, forecasts and strategies and (ii) to make strategic decisions regarding resource allocation, such as billable headcount and related compensation costs, as well as utilization and bill rates of our service offerings. Our CODM is not provided asset information by reportable segment.

Equity [Abstract]

Stockholders' Equity

Stockholders’ Equity

Stock Repurchase Program

On June 2, 2016, our Board of Directors authorized a stock repurchase program (the “Repurchase Program”), which was most recently increased by $500.0 million to an aggregate authorization of $2.2 billion on October 21, 2025. No time limit has been established for the completion of the Repurchase Program, and the Repurchase Program may be suspended, discontinued or replaced by the Board of Directors at any time without prior notice. As of December 31, 2025, we had $491.8 million available under the Repurchase Program to repurchase additional shares of our common stock.

The following table details our stock repurchases under the Repurchase Program:


	Year Ended December 31,
	2025		2024		2023
Shares of common stock repurchased and retired	5,265		52		112
Average price paid per share (1)	$	163.07	$	197.53	$	158.70
Total cost (1)	$	858,575	$	10,216	$	17,797

(1) Excludes excise tax of $8.0 million and commissions incurred during the year ended December 31, 2025.

As we repurchase our common shares, we reduce stated capital on our Consolidated Balance Sheets for the $0.01 of par value of the shares repurchased, with the excess purchase price over par value recorded as a reduction to additional paid-in capital. If additional paid-in capital is reduced to zero, we record the remainder of the excess purchase price over par value as a reduction of retained earnings.

Common Stock Outstanding

Common stock outstanding was approximately 30.9 million shares and 35.9 million shares as of December 31, 2025 and 2024, respectively. Common stock outstanding includes unvested restricted stock awards, which are considered issued and outstanding under the terms of the restricted stock award agreements. The decrease in common stock outstanding was primarily due to stock repurchases under the Repurchase Program during the year ended December 31, 2025.
