INCOME TAXES	9 Months Ended
INCOME TAXES	Sep. 30, 2024
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES At the end of each interim period, the Company estimates the annual expected effective income tax rate and applies that rate to its ordinary year-to-date earnings or loss. The income tax provision or benefit related to significant, unusual, or extraordinary items, if applicable, that will be separately reported or reported net of their related tax effects are individually computed and recognized in the interim period in which they occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or unrecognized tax benefits is recognized in the interim period in which the change occurs. The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected pre-tax income (or loss) for the year, projections of the proportion of income (and/or loss) earned and taxed in foreign jurisdictions, permanent and temporary differences and the likelihood of the realization of deferred tax assets generated in the current year. The accounting estimates used to compute the provision or benefit for income taxes may change as new events occur, more experience is acquired, additional information is obtained or the Company's tax environment changes. To the extent that the expected annual effective income tax rate changes during a quarter, the effect of the change on prior quarters is included in income tax provision or benefit in the quarter in which the change occurs. For the three and nine months ended September 30, 2024, the Company recorded an income tax benefit of $115.8 million and $95.8 million, respectively, which represents an effective income tax rate of 33% and 22%, respectively. Following the purchase of the remaining noncontrolling interests of a foreign subsidiary, we reorganized related business operations, which resulted in the release of a valuation allowance for foreign net operating losses in the amount of $31.3 million as a discrete item in the third quarter because we are now forecasting the utilization of the net operating losses within the foreseeable future. For the three months ended September 30, 2024, the effective income tax rate was higher than the statutory rate of 21% due primarily to the valuation allowance release mentioned above and state taxes. For the nine months ended September 30, 2024, the effective income tax rate was higher than the statutory rate of 21% due primarily to the valuation allowance release mentioned above, research credits and the realization of capital losses, partially offset by nondeductible compensation expense and the nondeductible portion of goodwill in the sale of Mosaic Group. For the three and nine months ended September 30, 2023, the Company recorded an income tax benefit of $118.8 million and $3.6 million, respectively, which represents an effective income tax rate of 23% and 5%, respectively. For the three months ended September 30, 2023, the effective income tax rate was higher than the statutory rate of 21% due primarily to state taxes. For the nine months ended September 30, 2023, the effective income tax rate was lower than the statutory rate of 21% due primarily to non-deductible compensation expense, return to provision adjustments, foreign income taxed at different statutory rates and unconsolidated tax losses, partially offset by research credits and the realization of capital losses. The Company's income taxes are routinely under audit by federal, state, local and foreign authorities as a result of previously filed separate company and consolidated tax returns for periods prior to the June 30, 2020 separation of IAC from Match Group, Inc. (the "Match Separation") and for its tax returns filed on a standalone basis following the Match Separation. These audits include questioning the timing and the amount of income and deductions and the allocation of income and deductions among various tax jurisdictions. The Company is not currently under audit by the IRS. Returns filed in various other jurisdictions are open to examination for tax years beginning with 2014. Income taxes payable include unrecognized tax benefits considered sufficient to pay assessments that may result from the examination of prior year tax returns. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may not accurately anticipate actual outcomes and, therefore, may require periodic adjustment. Although management currently believes changes in unrecognized tax benefits from period to period and differences between amounts paid, if any, upon resolution of issues raised in audits and amounts previously provided will not have a material impact on the liquidity, results of operations, or financial condition of the Company, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future. The Company recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. At September 30, 2024 and December 31, 2023, accruals for interest and penalties are not material. At September 30, 2024 and December 31, 2023, unrecognized tax benefits, including interest and penalties, were $23.3 million and $19.6 million, respectively. Unrecognized tax benefits, including interest and penalties, at September 30, 2024 increased by $3.7 million due primarily to research credits. If unrecognized tax benefits at September 30, 2024 are subsequently recognized, $22.1 million, net of related deferred tax assets and interest, would reduce income tax expense. The comparable amount at December 31, 2023 was $18.6 million. The Company believes that it is reasonably possible that its unrecognized tax benefits could decrease by $0.3 million by September 30, 2025 due to expected settlements and statute expirations, all of which would reduce the income tax provision.

CONTINGENCIES	9 Months Ended
CONTINGENCIES	Sep. 30, 2024
Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES In the ordinary course of business, the Company is subject to various lawsuits and other contingent matters. The Company establishes accruals for specific legal and other matters when it determines that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable. Management has also identified certain legal and other matters where it believes an unfavorable outcome is not probable and, therefore, no accrual is established. Although management currently believes that resolving claims against the Company, including claims where an unfavorable outcome is reasonably possible, and for which the Company cannot estimate a loss or range of loss, will not have a material impact on the liquidity, results of operations, or financial condition of the Company, these matters are subject to inherent uncertainties and management's view of these matters may change in the future. The Company also evaluates other contingent matters, including unrecognized tax benefits and non-income tax contingencies, to assess the likelihood of an unfavorable outcome and estimated extent of potential loss. It is possible that an unfavorable outcome of one or more of these lawsuits or other contingencies could have a material impact on the liquidity, results of operations, or financial condition of the Company. See "Note 7—Income Taxes" for information related to unrecognized tax benefits.

- Definition

The entire disclosure for loss and gain contingencies. Describes any existing condition, situation, or set of circumstances involving uncertainty as of the balance sheet date (or prior to issuance of the financial statements) as to a probable or reasonably possible loss incurred by an entity that will ultimately be resolved when one or more future events occur or fail to occur, and typically discloses the amount of loss recorded or a range of possible loss, or an assertion that no reasonable estimate can be made.

The Company froze and terminated the domestic funded pension plan as of December 31, 2022. The last of the required customary regulatory approvals of the termination of this plan was received in February 2024. In connection with the termination of this plan, the liabilities were settled through a combination of (i) lump sum payments to eligible participants who elected to receive them and (ii) the purchase of annuity contracts for participants who either did not elect lump sums or were already receiving benefits. During the third quarter of 2024, the domestic funded pension plan’s remaining assets of $15.3 million were transferred to a suspense account in the trust for the IAC Inc. Retirement Savings Plan (the "IAC Plan"), a qualified retirement plan ("QRP"). In accordance with Internal Revenue Service ("IRS") requirements, assets in the suspense account are to be allocated to active Dotdash Meredith participants in the IAC Plan no less than ratably over a period not to exceed seven years, which may be accelerated. During the third quarter of 2024, Dotdash Meredith made its first asset allocation under the requirements. The assets were transferred to a fund that is considered to be a fair value hierarchy Level 2 investment. The amount transferred to the QRP is reflected as a retirement investment fund in "Other non-current assets" in the balance sheet, and the account is restricted in nature.

The actuarial gain of $4.4 million and $5.5 million for the three and nine months ended September 30, 2024, respectively, primarily relates to the final annuity contract pricing and lump sum payments for the domestic funded pension plan, partially offset by investment performance and plan expenses. The actuarial gain of $1.0 million and $1.2 million for the three and nine months ended September 30, 2023, respectively, primarily relates to updates to participant census data, investment performance and an increase in the discount rate.

The following table summarizes the weighted average expected return on plan assets used to determine the net periodic benefit (credit) cost at September 30, 2024 following the remeasurements, and December 31, 2023, respectively:


	September 30, 2024		December 31, 2023
	Pension
	Domestic			Domestic
Expected return on plan assets	5.22	%		4.48	%

The components of net periodic benefit (credit) cost, other than the service cost component, are included in "Other income, net" in the statement of operations.

Roofing does not meet the threshold to be reflected as a discontinued operation at the IAC level. During the fourth quarter of 2023, IAC moved Roofing to Emerging & Other and prior period financial information has been recast to conform to this presentation. Following IAC's move of Roofing to Emerging & Other, Angi has three operating segments: (i) Ads and Leads, (ii) Services and (iii) International (includes Europe and Canada). Basis of Presentation The Company prepares its consolidated financial statements (referred to herein as "financial statements") in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP"). The financial statements include the accounts of the Company, all entities that are wholly-owned by the Company and all entities in which the Company has a controlling financial interest. All intercompany transactions and balances between and among the Company and its subsidiaries have been eliminated. The unaudited interim financial statements have been prepared in accordance with GAAP for interim financial information and with the rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and notes required by GAAP for complete annual financial statements. In the opinion of management, the unaudited interim financial statements include all normal recurring adjustments considered necessary for a fair presentation. Interim results are not necessarily indicative of the results that may be expected for the full year. The unaudited interim financial statements should be read in conjunction with the annual audited financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. Accounting Estimates Management of the Company is required to make certain estimates, judgments and assumptions during the preparation of its financial statements in accordance with GAAP. These estimates, judgments and assumptions impact the reported amounts of assets, liabilities, revenue and expenses and the related disclosure of assets and liabilities. Actual results could differ from these estimates. On an ongoing basis, the Company evaluates its estimates, judgments and assumptions, including those related to: the fair values of cash equivalents and marketable debt and equity securities; the carrying value of accounts receivable, including the determination of the allowance for credit losses; the determination of the customer relationship period for certain costs to obtain a contract with a customer; the recoverability of right-of-use assets ("ROU assets"); the useful lives and recoverability of buildings, capitalized software, equipment and leasehold improvements and definite-lived intangible assets; the recoverability of goodwill and indefinite-lived intangible assets; the fair value of equity securities without readily determinable fair values; the fair value of interest rate swaps; contingencies; unrecognized tax benefits; the liability for potential refunds and customer credits; the valuation allowance for deferred income tax assets; pension and postretirement benefit expenses, including actuarial assumptions regarding discount rates, expected returns on plan assets, inflation and healthcare costs; and the fair value of and forfeiture rates for stock-based awards, among others. The Company bases its estimates, judgments and assumptions on historical experience, its forecasts and budgets and other factors that the Company considers relevant. Interest Rate Swaps In March 2023, Dotdash Meredith entered into interest rate swaps for a total notional amount of $350 million, which synthetically converted a portion of the Dotdash Meredith Term Loan B due December 1, 2028 ("Dotdash Meredith Term Loan B") from a variable rate to a fixed rate to manage interest rate risk exposure for the period commencing April 3, 2023 and ending April 1, 2027. Dotdash Meredith designated the interest rate swaps as cash flow hedges and applies hedge accounting to these contracts in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 815, Derivatives and Hedging. As cash flow hedges, the interest rate swaps are recognized at fair value on the balance sheet as either assets or liabilities, with the changes in fair value recorded in "Accumulated other comprehensive loss" in the balance sheet and reclassified into “Interest expense” in the statement of operations in the periods in which the interest rate swaps affect earnings. Dotdash Meredith assessed hedge effectiveness at the time of entering into these agreements and determined these interest rate swaps are expected to be highly effective. Dotdash Meredith evaluates the hedge effectiveness of the interest rate swaps quarterly, or more frequently, if necessary, by verifying (i) that the critical terms of the interest rate swaps continue to match the critical terms of the hedged interest payments and (ii) that it is probable the counterparties will not default. If the two requirements are met, the interest rate swaps are determined to be effective and all changes in the fair value of the interest rate swaps are recorded in "Accumulated other comprehensive loss." The cash flows related to interest settlements of the hedged monthly interest payments are classified as operating activities in the statement of cash flows, consistent with the interest expense on the related Dotdash Meredith Term Loan B. See "Note 3—Long-term Debt" for additional information. General Revenue Recognition The Company accounts for a contract with a customer when it has approval and commitment from all authorized parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue is recognized when control of the promised services or goods is transferred to the Company's customers and in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services or goods. The Company's disaggregated revenue disclosures are presented in "Note 5—Segment Information." Deferred Revenue Deferred revenue consists of payments that are received or are contractually due in advance of the Company's performance obligation. The Company’s deferred revenue is reported on a contract-by-contract basis at the end of each reporting period. The Company classifies deferred revenue as current when the remaining term or expected completion of its performance obligation is one year or less. The current and non-current deferred revenue balances were $117.0 million and $0.1 million, respectively, at September 30, 2024, and $143.4 million and $0.1 million, respectively, at December 31, 2023. During the nine months ended September 30, 2024, the Company recognized $108.3 million of revenue that was included in the deferred revenue balance at December 31, 2023. The change in the deferred revenue balance from December 31, 2023 to September 30, 2024 also reflects the reduction of $33.2 million related to the sale of Mosaic Group in the first quarter of 2024. During the nine months ended September 30, 2023, the Company recognized $147.8 million of revenue that was included in the deferred revenue balance at December 31, 2022. The current and non-current deferred revenue balances were $157.1 million and $0.2 million, respectively, at December 31, 2022. Non-current deferred revenue is included in "Other long-term liabilities" in the balance sheet. Practical Expedients and Exemptions For contracts that have an original duration of one year or less, the Company uses the practical expedient available under ASC Topic 606, Revenue from Contracts with Customers ("ASC 606"), applicable to such contracts and does not consider the time value of money. In addition, as permitted under the practical expedient available under ASC 606, the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts with variable consideration that is tied to sales-based or usage-based royalties, allocated entirely to unsatisfied performance obligations, or to a wholly unsatisfied promise accounted for under the series guidance, and (iii) contracts for which the Company recognizes revenue at the amount which it has the right to invoice for services performed. The Company also applies the practical expedient to expense sales commissions as incurred where the anticipated customer relationship period is one year or less. Certain Risks and Concentrations—Services Agreement with Google (the "Services Agreement") The Company and Google are parties to an amended Services Agreement, which automatically renewed effective March 31, 2023 and expires on March 31, 2025. The Company earns certain other advertising revenue from Google that is not attributable to the Services Agreement. A portion of the Company’s net cash from operating activities that it can freely access is attributable to revenue earned pursuant to the Services Agreement and other revenue earned from Google. For the three and nine months ended September 30, 2024, total revenue earned from Google was $116.6 million and $374.5 million, respectively, representing 12% and 13%, respectively, of the Company's revenue. The total revenue earned from the Services Agreement for the three and nine months ended September 30, 2024 was $86.0 million and $287.3 million, respectively, representing 9% and 10%, respectively, of the Company's total revenue. For the three and nine months ended September 30, 2023, total revenue earned from Google was $180.3 million and $551.0 million, respectively, representing 16% and 17%, respectively, of the Company's revenue. The total revenue earned from the Services Agreement for the three and nine months ended September 30, 2023 was $149.4 million and $452.7 million, respectively, representing 13% and 14%, respectively, of the Company's total revenue. The related accounts receivable totaled $43.4 million and $52.2 million at September 30, 2024 and December 31, 2023, respectively. The revenue attributable to the Services Agreement is earned by Ask Media Group and the Desktop business, which comprise the Search segment. For the three and nine months ended September 30, 2024, revenue earned from the Services Agreement was $70.9 million and $238.1 million, respectively, within Ask Media Group and $15.0 million and $49.2 million, respectively, within the Desktop business. For the three and nine months ended September 30, 2023, revenue earned from the Services Agreement was $131.9 million and $398.3 million, respectively, within Ask Media Group and $17.5 million and $54.4 million, respectively, within the Desktop business. The Services Agreement requires that the Company comply with certain guidelines promulgated by Google. Google may generally unilaterally update its policies and guidelines without advance notice. These updates may be specific to the Services Agreement or could be more general and thereby impact the Company as well as other companies. These policy and guideline updates have in the past (and could in the future) require modifications to, or prohibit and/or render obsolete certain of our products, services and/or business practices, which have negatively impacted revenue and been costly to address (and could in the future), which have had and could have an adverse effect on our business, financial condition and results of operations. Recent Accounting Pronouncements Recent Accounting Pronouncements Adopted by the Company There were no recently issued accounting pronouncements adopted by the Company during the nine months ended September 30, 2024. Recent Accounting Pronouncements Not Yet Adopted by the Company Accounting Standards Update ("ASU") No. 2023-07—Segment Reporting (Topic 280)—Improvements to Reportable Segment Disclosures In November 2023, the FASB issued ASU No. 2023-07, which is intended to provide users of financial statements with more decision-useful information about reportable segments of a public business entity, primarily through enhanced disclosures of significant segment expenses. This ASU requires annual and interim disclosures of significant expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss and an amount and description of its composition of other segment items. The provisions of this ASU also require entities to include all annual disclosures required by Topic 280 in the interim periods and permits entities to include multiple measures of a segment's profit or loss if such measures are used by the CODM to assess segment performance and determine allocation of resources, provided that at least one of those measures is determined in a way that is consistent with the measurement principles under GAAP. The amendments in ASU No. 2023-07 apply retrospectively and are effective for fiscal years beginning after December 15, 2023 and interim periods after December 15, 2024, early adoption is permitted. The Company, as required, will adopt ASU No. 2023-07 in its financial statements for the year ending December 31, 2024. ASU No. 2023-07 will not impact the Company's results of operations, financial condition or cash flows. The Company is assessing the form and content of the disclosure of its significant segment expenses as required by ASU No. 2023-07. ASU No. 2023-09—Income Taxes (Topic 740)—Improvements to Income Tax Disclosures In December 2023, the FASB issued ASU No. 2023-09, which establishes required categories and a quantitative threshold to the annual tabular rate reconciliation disclosure and disaggregated jurisdictional disclosures of income taxes paid. The guidance's annual requirements are effective for the Company beginning with the December 31, 2025 reporting period. Early adoption is permitted and prospective disclosure should be applied. However, retrospective disclosure is permitted. The Company is currently assessing ASU No. 2023-09 and its impact on its income tax disclosures; ASU No. 2023-09 does not impact the Company's results of operations, financial condition or cash flows. The Company does not plan to early adopt ASU No. 2023-09. ASU No. 2024-03—Income Statement-Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40)—Disaggregation of Income Statement Expenses In November 2024, the FASB issued ASU No. 2024-03, which is intended to provide users of financial statements with more decision-useful information about expenses of a public business entity, primarily through enhanced disclosures of certain components of expenses commonly presented within captions on the statement of operations, such as purchases of inventory, employee compensation, depreciation and amortization, as well as a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. ASU No. 2024-03 also requires disclosure of the total amount of selling expenses and, in annual reporting periods, the definition of selling expenses. ASU No. 2024-03 is effective for fiscal years beginning after December 15, 2026 and for interim periods beginning after December 15, 2027. Early adoption is permitted and may be applied either prospectively or retrospectively. The Company is currently assessing ASU No. 2024-03 and its impact on its disclosures; ASU No. 2024-03 does not impact the Company's results of operations, financial condition or cash flows. Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation.

Earnings Per Share [Abstract]

LOSS PER SHARE

The Company treats its common stock and Class B common stock as one class of stock for net earnings (loss) per share ("EPS") purposes as both classes of stock participate in earnings, dividends and other distributions on the same basis. The restricted stock award granted to our Chief Executive Officer ("CEO") on November 5, 2020 is a participating security and the Company calculates basic EPS using the two-class method since those restricted shares are unvested and have a non-forfeitable dividend right in the event the Company declares a cash dividend on common shares and participate in all other distributions of the Company in the same manner as all other IAC common shares. Diluted EPS is calculated on the most dilutive basis, which excludes stock-based awards that would be anti-dilutive, including the restricted stock award granted to our CEO.

Undistributed earnings allocated to the participating security is subtracted from earnings in determining earnings attributable to holders of IAC common stock and Class B common stock for basic EPS. Basic EPS is computed by dividing net earnings (loss) attributable to holders of IAC common stock and Class B common stock by the weighted-average number of shares of common stock and Class B common stock outstanding during the period.

For the calculation of diluted EPS, net earnings (loss) attributable to holders of IAC common stock and Class B common stock is adjusted for the impact from our public subsidiary's dilutive securities, if applicable, and the reallocation of undistributed earnings allocated to the participating security by the weighted-average number of common stock and Class B common stock outstanding plus dilutive securities during the period.

The numerator and denominator of basic and diluted EPS computations for the Company’s common stock and Class B common stock are calculated as follows:

_____________________

(a) On November 5, 2020, IAC's CEO was granted a stock-based award in the form of 3.0 million shares of restricted common stock (the "restricted shares"). The number of restricted shares that ultimately vests is subject to the satisfaction of growth targets in IAC's stock price over the 10-year service condition of the award. These restricted shares have a non-forfeitable dividend right in the event the Company declares a cash dividend on its common shares and participate in all other distributions of the Company in the same manner as all other IAC common shares. Accordingly, the two-class method of calculating EPS is used. While the restricted shares are presented as outstanding shares in the balance sheet, these shares are excluded from the weighted average shares outstanding in calculating basic EPS and the allocable portion of net earnings are also excluded. Fully diluted EPS reflects the impact on earnings and fully diluted shares in the manner that is most dilutive.

(b) IAC has the option to settle certain Angi stock-based awards in its shares. The impact on net earnings relates to the settlement of Angi's dilutive securities in IAC common shares. For the three and nine months ended September 30, 2024 and 2023, these Angi equity awards were anti-dilutive.

(c) For the three and nine months ended September 30, 2024 and 2023, the Company had a loss from operations and as a result approximately 7.8 million and 8.0 million of potentially dilutive securities, respectively, were excluded from computing diluted EPS for each of those periods because the impact would have been anti-dilutive. Accordingly, the weighted average basic shares outstanding were used to compute the EPS amounts for the three and nine months ended September 30, 2024 and 2023.

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Nature of Operations IAC today is comprised of category leading businesses, including Dotdash Meredith, Angi Inc. ("Angi") and Care.com, as well as others ranging from early stage to established businesses. As used herein, “IAC,” the “Company,” “we,” “our,” “us” and other similar terms refer to IAC Inc. and its subsidiaries (unless the context requires otherwise).
Basis of Presentation	Basis of Presentation The Company prepares its consolidated financial statements (referred to herein as "financial statements") in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP"). The financial statements include the accounts of the Company, all entities that are wholly-owned by the Company and all entities in which the Company has a controlling financial interest. All intercompany transactions and balances between and among the Company and its subsidiaries have been eliminated. The unaudited interim financial statements have been prepared in accordance with GAAP for interim financial information and with the rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and notes required by GAAP for complete annual financial statements. In the opinion of management, the unaudited interim financial statements include all normal recurring adjustments considered necessary for a fair presentation. Interim results are not necessarily indicative of the results that may be expected for the full year. The unaudited interim financial statements should be read in conjunction with the annual audited financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023.
Accounting Estimates	Accounting Estimates Management of the Company is required to make certain estimates, judgments and assumptions during the preparation of its financial statements in accordance with GAAP. These estimates, judgments and assumptions impact the reported amounts of assets, liabilities, revenue and expenses and the related disclosure of assets and liabilities. Actual results could differ from these estimates. On an ongoing basis, the Company evaluates its estimates, judgments and assumptions, including those related to: the fair values of cash equivalents and marketable debt and equity securities; the carrying value of accounts receivable, including the determination of the allowance for credit losses; the determination of the customer relationship period for certain costs to obtain a contract with a customer; the recoverability of right-of-use assets ("ROU assets"); the useful lives and recoverability of buildings, capitalized software, equipment and leasehold improvements and definite-lived intangible assets; the recoverability of goodwill and indefinite-lived intangible assets; the fair value of equity securities without readily determinable fair values; the fair value of interest rate swaps; contingencies; unrecognized tax benefits; the liability for potential refunds and customer credits; the valuation allowance for deferred income tax assets; pension and postretirement benefit expenses, including actuarial assumptions regarding discount rates, expected returns on plan assets, inflation and healthcare costs; and the fair value of and forfeiture rates for stock-based awards, among others. The Company bases its estimates, judgments and assumptions on historical experience, its forecasts and budgets and other factors that the Company considers relevant.
Interest Rate Swaps	Interest Rate Swaps In March 2023, Dotdash Meredith entered into interest rate swaps for a total notional amount of $350 million, which synthetically converted a portion of the Dotdash Meredith Term Loan B due December 1, 2028 ("Dotdash Meredith Term Loan B") from a variable rate to a fixed rate to manage interest rate risk exposure for the period commencing April 3, 2023 and ending April 1, 2027. Dotdash Meredith designated the interest rate swaps as cash flow hedges and applies hedge accounting to these contracts in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 815, Derivatives and Hedging. As cash flow hedges, the interest rate swaps are recognized at fair value on the balance sheet as either assets or liabilities, with the changes in fair value recorded in "Accumulated other comprehensive loss" in the balance sheet and reclassified into “Interest expense” in the statement of operations in the periods in which the interest rate swaps affect earnings. Dotdash Meredith assessed hedge effectiveness at the time of entering into these agreements and determined these interest rate swaps are expected to be highly effective. Dotdash Meredith evaluates the hedge effectiveness of the interest rate swaps quarterly, or more frequently, if necessary, by verifying (i) that the critical terms of the interest rate swaps continue to match the critical terms of the hedged interest payments and (ii) that it is probable the counterparties will not default. If the two requirements are met, the interest rate swaps are determined to be effective and all changes in the fair value of the interest rate swaps are recorded in "Accumulated other comprehensive loss." The cash flows related to interest settlements of the hedged monthly interest payments are classified as operating activities in the statement of cash flows, consistent with the interest expense on the related Dotdash Meredith Term Loan B. See "Note 3—Long-term Debt" for additional information.
General Revenue Recognition	General Revenue Recognition The Company accounts for a contract with a customer when it has approval and commitment from all authorized parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue is recognized when control of the promised services or goods is transferred to the Company's customers and in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services or goods. The Company's disaggregated revenue disclosures are presented in "Note 5—Segment Information." Deferred Revenue Deferred revenue consists of payments that are received or are contractually due in advance of the Company's performance obligation. The Company’s deferred revenue is reported on a contract-by-contract basis at the end of each reporting period. The Company classifies deferred revenue as current when the remaining term or expected completion of its performance obligation is one year or less. The current and non-current deferred revenue balances were $117.0 million and $0.1 million, respectively, at September 30, 2024, and $143.4 million and $0.1 million, respectively, at December 31, 2023. During the nine months ended September 30, 2024, the Company recognized $108.3 million of revenue that was included in the deferred revenue balance at December 31, 2023. The change in the deferred revenue balance from December 31, 2023 to September 30, 2024 also reflects the reduction of $33.2 million related to the sale of Mosaic Group in the first quarter of 2024. During the nine months ended September 30, 2023, the Company recognized $147.8 million of revenue that was included in the deferred revenue balance at December 31, 2022. The current and non-current deferred revenue balances were $157.1 million and $0.2 million, respectively, at December 31, 2022. Non-current deferred revenue is included in "Other long-term liabilities" in the balance sheet. Practical Expedients and Exemptions For contracts that have an original duration of one year or less, the Company uses the practical expedient available under ASC Topic 606, Revenue from Contracts with Customers ("ASC 606"), applicable to such contracts and does not consider the time value of money. In addition, as permitted under the practical expedient available under ASC 606, the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts with variable consideration that is tied to sales-based or usage-based royalties, allocated entirely to unsatisfied performance obligations, or to a wholly unsatisfied promise accounted for under the series guidance, and (iii) contracts for which the Company recognizes revenue at the amount which it has the right to invoice for services performed. The Company also applies the practical expedient to expense sales commissions as incurred where the anticipated customer relationship period is one year or less.
Certain Risks and Concentrations—Services Agreement with Google (the "Services Agreement")	Certain Risks and Concentrations—Services Agreement with Google (the "Services Agreement") The Company and Google are parties to an amended Services Agreement, which automatically renewed effective March 31, 2023 and expires on March 31, 2025. The Company earns certain other advertising revenue from Google that is not attributable to the Services Agreement. A portion of the Company’s net cash from operating activities that it can freely access is attributable to revenue earned pursuant to the Services Agreement and other revenue earned from Google. The Services Agreement requires that the Company comply with certain guidelines promulgated by Google. Google may generally unilaterally update its policies and guidelines without advance notice. These updates may be specific to the Services Agreement or could be more general and thereby impact the Company as well as other companies. These policy and guideline updates have in the past (and could in the future) require modifications to, or prohibit and/or render obsolete certain of our products, services and/or business practices, which have negatively impacted revenue and been costly to address (and could in the future), which have had and could have an adverse effect on our business, financial condition and results of operations.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recent Accounting Pronouncements Adopted by the Company There were no recently issued accounting pronouncements adopted by the Company during the nine months ended September 30, 2024. Recent Accounting Pronouncements Not Yet Adopted by the Company Accounting Standards Update ("ASU") No. 2023-07—Segment Reporting (Topic 280)—Improvements to Reportable Segment Disclosures In November 2023, the FASB issued ASU No. 2023-07, which is intended to provide users of financial statements with more decision-useful information about reportable segments of a public business entity, primarily through enhanced disclosures of significant segment expenses. This ASU requires annual and interim disclosures of significant expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss and an amount and description of its composition of other segment items. The provisions of this ASU also require entities to include all annual disclosures required by Topic 280 in the interim periods and permits entities to include multiple measures of a segment's profit or loss if such measures are used by the CODM to assess segment performance and determine allocation of resources, provided that at least one of those measures is determined in a way that is consistent with the measurement principles under GAAP. The amendments in ASU No. 2023-07 apply retrospectively and are effective for fiscal years beginning after December 15, 2023 and interim periods after December 15, 2024, early adoption is permitted. The Company, as required, will adopt ASU No. 2023-07 in its financial statements for the year ending December 31, 2024. ASU No. 2023-07 will not impact the Company's results of operations, financial condition or cash flows. The Company is assessing the form and content of the disclosure of its significant segment expenses as required by ASU No. 2023-07. ASU No. 2023-09—Income Taxes (Topic 740)—Improvements to Income Tax Disclosures In December 2023, the FASB issued ASU No. 2023-09, which establishes required categories and a quantitative threshold to the annual tabular rate reconciliation disclosure and disaggregated jurisdictional disclosures of income taxes paid. The guidance's annual requirements are effective for the Company beginning with the December 31, 2025 reporting period. Early adoption is permitted and prospective disclosure should be applied. However, retrospective disclosure is permitted. The Company is currently assessing ASU No. 2023-09 and its impact on its income tax disclosures; ASU No. 2023-09 does not impact the Company's results of operations, financial condition or cash flows. The Company does not plan to early adopt ASU No. 2023-09. ASU No. 2024-03—Income Statement-Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40)—Disaggregation of Income Statement Expenses In November 2024, the FASB issued ASU No. 2024-03, which is intended to provide users of financial statements with more decision-useful information about expenses of a public business entity, primarily through enhanced disclosures of certain components of expenses commonly presented within captions on the statement of operations, such as purchases of inventory, employee compensation, depreciation and amortization, as well as a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. ASU No. 2024-03 also requires disclosure of the total amount of selling expenses and, in annual reporting periods, the definition of selling expenses. ASU No. 2024-03 is effective for fiscal years beginning after December 15, 2026 and for interim periods beginning after December 15, 2027. Early adoption is permitted and may be applied either prospectively or retrospectively. The Company is currently assessing ASU No. 2024-03 and its impact on its disclosures; ASU No. 2024-03 does not impact the Company's results of operations, financial condition or cash flows.

Segment Reporting [Abstract]

SEGMENT INFORMATION

Our reportable segments currently consist of Dotdash Meredith (Digital and Print), Angi (Ads and Leads, Services and International) and Search. Our CODM regularly reviews certain financial information by operating segment to determine allocation of resources and assess its performance. Segment profitability is determined by and presented on an Adjusted EBITDA basis consistent with the CODM’s view of profitability of its businesses, which excludes certain expenses that are required in accordance with GAAP. While not considered a reportable segment, Emerging & Other comprises various operating segments that do not meet the quantitative thresholds that require presentation as separate reportable segments.

The following table presents revenue by reportable segment:

RELATED PARTY TRANSACTIONS	9 Months Ended
RELATED PARTY TRANSACTIONS	Sep. 30, 2024
Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS IAC and Angi Allocation of CEO Compensation and Certain Expenses Joseph Levin, CEO of IAC and Chairman of Angi, was CEO of Angi from October 10, 2022 through April 8, 2024. As a result, IAC allocated $2.4 million for the nine months ended September 30, 2024 and $2.6 million and $7.2 million for the three and nine months ended September 30, 2023, respectively, in costs to Angi (including salary, benefits, stock-based compensation and costs related to the CEO's office). These costs were allocated from IAC based upon time spent on Angi by Mr. Levin. Management considers the allocation method to be reasonable. The allocated costs also include costs directly attributable to Angi that were initially paid for by IAC and billed by IAC to Angi. On April 8, 2024, Jeffrey W. Kip, President of Angi, was appointed to succeed Joseph Levin as CEO of Angi. Mr. Levin remains Chairman of the Angi board of directors. The Combination and Related Agreements The Company and Angi, in connection with the transaction resulting in the formation of Angi in 2017, which is referred to as the "Combination," entered into a contribution agreement; an investor rights agreement; a services agreement; a tax sharing agreement; and an employee matters agreement, which collectively govern the relationship between IAC and Angi. IAC and Vimeo Inc. ("Vimeo") In connection with the spin-off of Vimeo from IAC, the parties entered in several agreements to govern their relationship following the completion of the transaction, certain of which remain in effect and are as follows: a separation agreement, a tax matters agreement and an employee matters agreement. Following the completion of the transaction, Vimeo and IAC entered into certain commercial agreements, including lease agreements. The Company and Vimeo are related parties because Mr. Diller is the beneficial owner of more than ten percent of the voting interests in both IAC and Vimeo. The Company charged Vimeo rent pursuant to lease agreements of $0.9 million and $2.6 million for both the three and nine months ended September 30, 2024 and 2023, respectively. The Company had non-current rent receivable amounts of $0.4 million and $0.3 million at September 30, 2024 and December 31, 2023, respectively, due from Vimeo pursuant to the lease agreements. These amounts are included in "Other non-current assets" in the balance sheet. IAC and Expedia Group At September 30, 2024, the Company and Expedia Group each had a 50% ownership interest in two aircraft that may be used by both companies. Members of the aircraft flight crews are employed by an entity in which the Company and Expedia Group each have a 50% ownership interest. The Company and Expedia Group have agreed to share costs relating to flight crew compensation and benefits pro-rata according to each company’s respective usage of the aircraft, for which they are separately billed by the entity described above. The Company and Expedia Group are related parties because Mr. Diller serves as Chairman and Senior Executive of both IAC and Expedia Group. For both the three and nine months ended September 30, 2024 and 2023, total payments made to this entity by the Company were not material. Expedia Group may also use certain aircraft owned 100% by a subsidiary of the Company on a cost basis. For both the three and nine months ended September 30, 2024 and 2023, the payments made by Expedia Group to the Company pursuant to this arrangement were not material. During the second quarter of 2024, the Company and Expedia Group entered into a five-year lease agreement, commencing October 2024, for Expedia Group to occupy office space in the Company's New York City headquarters building. The total payments pursuant to this lease agreement are not material.

Available-for-sale marketable debt securities	$	24,947	$	148,998
Total marketable securities	$	24,947	$	148,998

Marketable securities are carried at fair value. The Company has no investments in marketable equity securities, following the change in classification of its investment in MGM Resorts International ("MGM") to an equity method investment in the fourth quarter of 2023, described below. Prior to the fourth quarter of 2023, the Company had two investments in marketable equity securities, other than its investment in MGM, including one investment that was fully impaired in the first quarter of 2023 due to the investee declaring bankruptcy and another investment that was sold in the third quarter of 2023, resulting in a net pre-tax gain of $0.1 million. The Company recorded a net unrealized pre-tax loss of $0.3 million during the nine months ended September 30, 2023 for these investments. The realized and unrealized pre-tax gain and loss related to these investments are included in "Other income, net" in the statement of operations.

At September 30, 2024 and December 31, 2023, current available-for-sale marketable debt securities are as follows:


	September 30, 2024								December 31, 2023

The contractual maturities of debt securities classified as current available-for-sale at September 30, 2024 and December 31, 2023 were within one year. There were no investments in available-for-sale marketable debt securities that had been in a continuous unrealized loss position for longer than twelve months at September 30, 2024 and December 31, 2023.

Investment in MGM Resorts International


	September 30, 2024		December 31, 2023
	(In thousands)
Investment in MGM	$	2,530,045	$	2,891,850

At September 30, 2024, the Company owns 64.7 million common shares of MGM, which represents 21.8% of MGM's common shares outstanding. During the fourth quarter of 2023, due to MGM's ongoing share repurchase program, which passively increased the Company's ownership interest, the Company determined that the equity method of accounting applied and elected to account for its investment in MGM pursuant to the fair value option. Prior to the fourth quarter of 2023, the Company's investment in MGM was accounted for as an equity security with a readily determinable fair value, with changes in fair value recognized through income each period. Since the Company has always marked its investment in MGM to fair value through income each period the election of the fair value option results in no change from its historical accounting for this investment. The fair value of the investment in MGM is remeasured each reporting period based upon MGM's closing stock price on the New York Stock Exchange on the last trading day in the reporting period and any unrealized pre-tax gains or losses are included in the statement of operations. For the three and nine months ended September 30, 2024, the Company recorded unrealized pre-tax losses on its investment in MGM of $346.3 million and $361.8 million, respectively. For the three and nine months ended September 30, 2023, the Company recorded an unrealized pre-tax loss and gain on its investment of MGM of $463.4 million and $209.1 million, respectively. The cumulative unrealized net pre-tax gain through September 30, 2024 is $1.3 billion. A $2.00 increase or decrease in the share price of MGM would result in an unrealized gain or loss, respectively, of $129.4 million. At November 8, 2024, the fair value of the Company's investment in MGM was $2.4 billion.

Fair Value Measurements

The Company categorizes its financial instruments measured at fair value into a fair value hierarchy that prioritizes the inputs used in pricing the asset or liability. The three levels of the fair value hierarchy are:

•Level 1: Observable inputs obtained from independent sources, such as quoted market prices for identical assets and liabilities in active markets.

•Level 2: Other inputs, which are observable directly or indirectly, such as quoted market prices for similar assets or liabilities in active markets, quoted market prices for identical or similar assets or liabilities in markets that are not active and inputs that are derived principally from or corroborated by observable market data. The fair values of the Company's Level 2 financial assets are primarily obtained from observable market prices for identical underlying securities that may not be actively traded. Certain of these securities may have different market prices from multiple market data sources, in which case an average market price is used.

•Level 3: Unobservable inputs for which there is little or no market data and require the Company to develop its own assumptions, based on the best information available in the circumstances, about the assumptions market participants would use in pricing the assets or liabilities.

The following tables present the Company's financial instruments that are measured at fair value on a recurring basis:

Warrant

The Company owns preferred shares of Turo Inc. ("Turo"), a peer-to-peer car sharing marketplace, which are accounted for as an equity security without a readily determinable fair value, as the preferred shares are not common stock equivalents. As part of the Company's original investment in Turo preferred shares, the Company received a warrant that was recorded at fair value each reporting period with any change in fair value included in "Other income, net" in the statement of operations. The warrant was measured using significant unobservable inputs and classified in the fair value hierarchy table as Level 3. The Company net settled its Turo warrant on July 23, 2024 (the warrant expiration date) for 4.5 million shares of Series E-2 preferred stock and the fair value of the warrant of $70.0 million was reclassified to equity securities without readily determinable fair values. The Company had measured this warrant at fair value at June 30, 2024 using the settlement value of the shares received pursuant to its net exercise on July 23, 2024. For the periods prior to the settlement, the warrant was included in "Other non-current assets" in the balance sheet.

Assets measured at fair value on a nonrecurring basis

The Company's non-financial assets, such as goodwill, intangible assets, ROU assets, buildings, capitalized software, equipment and leasehold improvements, are adjusted to fair value only when an impairment is recognized. The Company's financial assets, comprising equity securities without readily determinable fair values, are adjusted to fair value when observable price changes for similar or identical securities are identified or an impairment is recognized. Such fair value measurements are based predominantly on Level 3 inputs.

Goodwill

During the third quarter of 2023, the Company reassessed the fair value of the Mosaic Group reporting unit (included in the Emerging & Other segment prior to the sale of its assets on February 15, 2024) and recorded a goodwill impairment of $9.0 million, as a result of the projected reduction in future revenue and profits from the business and lower trading multiples of a selected peer group of companies.

Intangible Asset

During the third quarter of 2023, the Company determined that a projected reduction in future revenue related to a certain indefinite-lived trade name intangible asset in the Dotdash Meredith Digital segment was an indicator of possible impairment. Following the identification of the indicator, the Company updated its calculation of the fair value of the indefinite-lived intangible asset and recorded an impairment of $7.6 million. The impairment of indefinite-lived intangible assets is included in “Amortization of intangibles” in the statement of operations. The Company determines the fair value of indefinite-lived intangible assets using an avoided royalty discounted cash flow ("DCF") valuation analysis.

ROU Assets and Related Leasehold Improvements, Furniture and Equipment

During the first quarter of 2023, Dotdash Meredith recorded impairment charges of $70.0 million related to certain unoccupied leased office space due to the continued decline in the commercial real estate market consisting of impairments of $44.7 million and $25.3 million of an ROU asset and related leasehold improvements, furniture and equipment, respectively.

The impairment charges related to ROU assets are included in "General and administrative expense" and the impairment charges related to leasehold improvements, furniture and equipment are included in "Depreciation" in the statement of operations. The impairment charges represent the amount by which the carrying value of the asset group exceeded its estimated fair value, calculated using a DCF approach using sublease market assumptions of the expected cash flows and discount rate. The impairment charges were allocated between the ROU assets and related leasehold improvements, furniture and equipment of the asset group based on their relative carrying values.

Financial instruments measured at fair value only for disclosure purposes

The total fair value of the outstanding long-term debt, including the current portion, is estimated using observable market prices or indices for similar liabilities, which are Level 2 inputs, and was approximately $1.98 billion and $1.95 billion at September 30, 2024 and December 31, 2023, respectively.

Dotdash Meredith Term Loans and Dotdash Meredith Revolving Facility

On December 1, 2021, Dotdash Meredith entered into a credit agreement ("Dotdash Meredith Credit Agreement"), which provides for (i) the five-year $350 million Dotdash Meredith Term Loan A due December 1, 2026 ("Dotdash Meredith Term Loan A"), (ii) the seven-year $1.25 billion Dotdash Meredith Term Loan B (together with the Dotdash Meredith Term Loan A, the "Dotdash Meredith Term Loans") and (iii) a five-year $150 million revolving credit facility ("Dotdash Meredith Revolving Facility"). The Dotdash Meredith Term Loan A bears interest at an adjusted term secured overnight financing rate ("Adjusted Term SOFR") as defined in the Dotdash Meredith Credit Agreement plus an applicable margin depending on Dotdash Meredith's most recently reported consolidated net leverage ratio, as defined in the Dotdash Meredith Credit Agreement. The adjustment to the secured overnight financing rate is fixed at 0.10% for the Dotdash Meredith Term Loan A. The Dotdash Meredith Term Loan B has a varying adjustment of 0.10%, 0.15% or 0.25% based upon the duration of the borrowing period. At September 30, 2024 and December 31, 2023, the Dotdash Meredith Term Loan A bore interest at Adjusted Term SOFR plus 2.25%, or 7.68% and 7.69%, respectively, and the Dotdash Meredith Term Loan B bore interest at Adjusted Term SOFR, subject to a minimum of 0.50%, plus 4.00%, or 9.30% and 9.44%, respectively. Interest payments are due at least quarterly through the terms of the Dotdash Meredith Term Loans.

In March 2023, Dotdash Meredith entered into interest rate swaps on the Dotdash Meredith Term Loan B for a total notional amount of $350 million with a maturity date of April 1, 2027. The interest rate swaps synthetically converted $350 million of the Dotdash Meredith Term Loan B for the duration of the interest rate swaps from a variable rate to a fixed rate of approximately 7.92% ((i) the weighted average fixed interest rate of approximately 3.82% on the interest rate swaps plus (ii) the adjustment to the secured overnight financing rate of 0.10% plus (iii) the base rate of 4.00%), beginning on April 3, 2023.

The interest rate swaps are expected to be highly effective. See "Note 4—Accumulated Other Comprehensive Loss" for the net unrealized gains and losses before reclassifications in "Accumulated other comprehensive loss" and realized gains reclassified into "Interest expense" for the three and nine months ended September 30, 2024 and 2023. At September 30, 2024, less than $0.1 million is expected to be reclassified into interest expense within the next twelve months as net realized losses.

The Dotdash Meredith Term Loan A requires quarterly principal payments of approximately $4.4 million through December 31, 2024, $8.8 million through December 31, 2025 and approximately $13.1 million thereafter through maturity. The Dotdash Meredith Term Loan B requires quarterly payments of $3.1 million through maturity. The Dotdash Meredith Term Loan B may require additional annual principal payments as part of an excess cash flow sweep provision, the amount of which, in part, is governed by the applicable net leverage ratio and further subject to the excess cash flow exceeding $80 million as defined in the Dotdash Meredith Credit Agreement. No such payment was required related to the period ended December 31, 2023.

There were no outstanding borrowings under the Dotdash Meredith Revolving Facility at September 30, 2024 and December 31, 2023. The annual commitment fee on undrawn funds is based on Dotdash Meredith's consolidated net leverage ratio, as defined in the Dotdash Meredith Credit Agreement, most recently reported and was 40 basis points at both September 30, 2024 and December 31, 2023. Any borrowings under the Dotdash Meredith Revolving Facility would bear interest, at Dotdash Meredith's option, at either a base rate or Adjusted Term SOFR, plus an applicable margin, which is based on Dotdash Meredith's consolidated net leverage ratio.

As of the last day of any calendar quarter, if either (i) $1.00 or more of loans under the Dotdash Meredith Revolving Facility or Dotdash Meredith Term Loan A are outstanding, or (ii) the outstanding face amount of undrawn letters of credit, other than cash collateralized letters of credit at 102% of face value, exceeds $25 million, subject to certain increases for qualifying material acquisitions, then Dotdash Meredith will not permit the consolidated net leverage ratio, which permits netting of up to $250 million in cash and cash equivalents, as of the last day of such quarter to exceed 5.5 to 1.0. This ratio was not exceeded for both test periods ended September 30, 2024 and December 31, 2023. The Dotdash Meredith Credit Agreement also contains covenants that would limit Dotdash Meredith’s ability to pay dividends, incur incremental secured indebtedness, or make distributions or certain investments in the event a default has occurred or if Dotdash Meredith’s consolidated net leverage ratio exceeds 4.0 to 1.0, subject to certain available amounts as defined in the Dotdash Meredith Credit Agreement. This ratio was exceeded for both test periods ended September 30, 2024 and December 31, 2023.

The Dotdash Meredith Credit Agreement also permits the Company to, among other things, contribute cash to Dotdash Meredith which will provide additional liquidity to ensure that Dotdash Meredith does not exceed certain consolidated net leverage ratios for any test period, as further defined in the Dotdash Meredith Credit Agreement. In connection with these capital contributions, Dotdash Meredith may make distributions to the Company in amounts not more than any such capital contributions, provided that no default has occurred and is continuing. Such capital contributions and subsequent distributions impact the consolidated net leverage ratios of Dotdash Meredith, however, absent these contributions, Dotdash Meredith's consolidated net leverage ratio would not have exceeded 5.5 to 1.0. During the three and nine months ended September 30, 2024, the Company contributed $20 million and $125 million, respectively, to Dotdash Meredith, following which Dotdash Meredith distributed $20 million in October 2024 back to the Company. During the three and nine months ended September 30, 2024, Dotdash Meredith distributed back to the Company $50 million and $210 million, respectively, including $105 million in January 2024 related to the Company's contribution in December 2023. During the three and nine months ended September 30, 2023, the Company contributed $125 million and $405 million, respectively, to Dotdash Meredith, and Dotdash Meredith distributed back to the Company $130 million and $280 million, respectively.

The obligations under the Dotdash Meredith Credit Agreement are guaranteed by certain of Dotdash Meredith's wholly-owned subsidiaries and are secured by substantially all of the assets of Dotdash Meredith and certain of its subsidiaries.
