(a) Q4 2018 operating income of $17.9 million at ANGI Homeservices includes $18.8 million in stock-based compensation expense and $0.1 million of other transaction-related items in connection with the Angie’s List transaction as well as $1.9 million in stock-based compensation expense and $2.4 million in transaction-related items in connection with the Handy acquisition; excluding these items, operating income would have been $41.1 million and Adjusted EBITDA would have been $68.7 million.

(b) Q4 2017 operating loss of $33.9 million at ANGI Homeservices includes $25.1 million in stock-based compensation expense and $22.0 million of other transaction-related items in connection with the Angie’s List transaction.

Match Group

·Revenue growth was due primarily to increased subscribers and ARPU at Tinder, partially offset by unfavorable foreign exchange effects.

·Operating income and Adjusted EBITDA grew slower than revenue due to higher cost of revenue, due to in-app purchase fees as revenue is increasingly sourced through mobile app stores, and higher legal costs.

Please refer to the Match Group Q4 2018 earnings release and the related investor presentation referenced therein for further detail.

Page 3 of 19

ANGI Homeservices

·Revenue increased 25% to $279.0 million driven by:

·37% Marketplace growth driven by a 24% increase in service requests to 5.3 million, an 18% increase in paying service professionals to 214,000 and a 16% increase in revenue per paying service professional (compared to 14% growth in Q3 2018)

·13% growth in Europe

·Pro forma revenue (excluding deferred revenue write-offs in connection with the Angie’s List transaction and Handy acquisition) increased 21% to $279.5 million.

·Operating income was $17.9 million in Q4 2018 compared to an operating loss of $33.9 million in Q4 2017 driven primarily by Adjusted EBITDA of $66.2 million in Q4 2018 compared to $16.2 million in Q4 2017.

·Items impacting Q4 2018

·$1.7 million in CEO-transition compensation-related expenses

Page 4 of 19

Vimeo

·Revenue increased 28% to $44.2 million driven by a 22% increase in average revenue per subscriber and a 9% increase in ending subscribers to 952,000.

·Operating loss increased 25% to $10.1 million and Adjusted EBITDA loss increased 32% to $8.4 million due primarily to higher marketing and legal costs, partially offset by higher Gross Profit margins (60% in Q4 2018 compared to 56% in Q4 2017).

Dotdash

·Revenue increased 32% to $40.2 million due to strong advertising growth across several verticals, particularly Verywell and The Spruce, as well as growth in affiliate commerce commissions.

·Operating income increased 140% to $11.8 million and Adjusted EBITDA increased 99% to $12.5 million, faster than revenue due to operating leverage across several expense categories.

Applications

·Revenue increased 10% to $153.3 million due to a 277% increase in Mobile, partially offset by a 15% decline in Desktop.

·Mobile revenue growth was driven by 136% growth related to the ongoing transition to subscription products, higher marketing and new products.  Mobile revenue growth was also attributable to iTranslate (acquired in Q1 2018), Daily Burn (moved to Applications effective April 1, 2018) and TelTech (acquired in Q4 2018).

·The lower Desktop revenue was driven by continued Partnerships declines as well as lower Consumer queries due primarily to the Google Chrome browser policy change in September 2018.

·Operating income decreased $25.6 million due primarily to an intangible asset impairment charge of $27.7 million related to a trade name and trademark at the Desktop business, partially offset by a 15% increase in Adjusted EBITDA to $34.7 million.

Page 5 of 19

Emerging & Other

·Revenue decreased 10% to $130.2 million due primarily to the sales of Electus and Dictionary.com in Q4 2018, IAC Films and Daily Burn (moved to Applications effective April 1, 2018), partially offset by higher revenue from Ask Media Group and BlueCrew (acquired in Q1 2018).

·Operating income decreased 43% to $6.5 million and Adjusted EBITDA decreased 40% to $7.4 million due primarily to the sales of Dictionary.com and Electus and investment in BlueCrew.

Corporate

Operating loss increased $10.0 million due primarily to a $10.7 million increase in stock-based compensation expense, due primarily to a mark-to-market adjustment and the modification of certain awards in connection with asset sales during the quarter.

Other income, net

Other income, net in Q4 2018 includes $120.6 million related to the pre-tax gains on the sales of Dictionary.com, Electus, Felix and CityGrid.

Income Taxes

In Q4 2018, the Company recorded an income tax provision of $19.7 million for an effective income tax rate of 8%, which is lower than the statutory rate of 21% due primarily to excess tax benefits generated by the exercise and vesting of stock-based awards.

In Q4 2017, the Company recorded an income tax provision of $31.8 million for an effective income tax rate of 58%, which is higher than the statutory rate of 21% due primarily to the one-time transition tax on foreign earnings, partially offset by excess tax benefits generated by the exercise and vesting of stock-based awards.

The Company does not expect to be a full US federal cash income tax payer until 2022, which is in line with previous estimates.  The ultimate timing is dependent primarily on the performance of the Company and the amount and timing of tax deductions related to stock-based awards.

Free Cash Flow

For the twelve months ended December 31, 2018, Free Cash Flow increased $561.3 million to $902.5 million due primarily to higher Adjusted EBITDA and favorable working capital.

DILUTIVE SECURITIES

IAC has various dilutive securities.  The table below details these securities as well as potential dilution at various stock prices (shares in millions; rounding differences may occur).

	Shares	Price		2/1/19			Dilution at:

Options	5.8	$	62.97	3.1			3.1			3.2			3.2			3.2

Total Diluted Shares Outstanding				87.1			87.1			87.2			87.2			87.2

The dilutive securities calculation in the above table is different from GAAP dilution, which is calculated based on the treasury method, and is based on the following assumptions:

RSUs and subsidiary denominated equity awards (excluding all ANGI Homeservices and Match Group and their subsidiary denominated awards) — These awards are settled on a net basis; therefore, the dilutive effect is presented as the net number of shares expected to be issued upon vesting or exercise, in each case assuming a withholding tax rate of 50%.  Withholding taxes paid by the Company on behalf of the employees upon vesting or exercise would have been $65.0 million, assuming a stock price of $211.09 and a 50% withholding rate.  In addition, the estimated income tax benefit from the tax deduction received upon the vesting or exercise of these awards is assumed to be used to repurchase IAC shares.

Upon exercise, if the Company decided to issue a sufficient number of shares to cover the $65.0 million employee withholding tax obligation above, 0.3 million additional shares would be issued.

Options — The cash generated from the exercise of all vested and unvested options, consisting of (a) the option exercise price and (b) the estimated income tax benefit from the tax deduction received upon the exercise of IAC options, is assumed to be used to repurchase IAC shares.

If options were net settled for employee withholding taxes at a 50% withholding rate, the dilution in the table shown above would be reduced by 2.0 million shares (1.3 million for vested options and 0.8 million for unvested options) and the withholding taxes paid by the Company on behalf of the employees would be $428.9 million ($270.3 million for vested options and $158.6 million for unvested options).

Exchangeable Senior Notes — No dilution is reflected in the table above for the 0.875% Exchangeable Senior Notes issued on October 2, 2017, which are exchangeable into IAC common shares at an initial conversion price of approximately $152.18 per share, because any dilution is offset by the assumed exercise of the bond hedge, which was purchased upon issuance of the Exchangeable Senior Notes.

ANGI Homeservices and Match Group Equity Awards and the Treatment of the Related Dilutive Effect

Certain ANGI Homeservices and Match Group equity awards can be settled either in IAC common shares or the common shares of these subsidiaries, at IAC’s election.  For purposes of the dilution calculation above, these awards are assumed to be settled in shares of ANGI Homeservices and Match Group common stock; therefore, no dilution from these awards is included.

IAC PRINCIPLES OF FINANCIAL REPORTING

IAC reports Adjusted EBITDA, Adjusted EBITDA margin and Free Cash Flow, all of which are supplemental measures to U.S. generally accepted accounting principles (“GAAP”).  These measures are among the primary metrics by which we evaluate the performance of our businesses, on which our internal budgets are based and by which management is compensated.  We believe that investors should have access to, and we are obligated to provide, the same set of tools that we use in analyzing our results.  These non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results.  IAC endeavors to compensate for the limitations of the non-GAAP measures presented by providing the comparable GAAP measures with equal or greater prominence and descriptions of the reconciling items, including quantifying such items, to derive the non-GAAP measures.  We encourage investors to examine the reconciling adjustments between the GAAP and non-GAAP measures, which are included in this release.  Interim results are not necessarily indicative of the results that may be expected for a full year.

Definitions of Non-GAAP Measures

Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (Adjusted EBITDA) is defined as operating income excluding: (1) stock-based compensation expense; (2) depreciation; and (3) acquisition-related items consisting of (i) amortization of intangible assets and impairments of goodwill and intangible assets, if applicable, and (ii) gains and losses recognized on changes in the fair value of contingent consideration arrangements.  We believe this measure is useful for analysts and investors as this measure allows a more meaningful comparison between our performance and that of our competitors.  The above items are excluded from our Adjusted EBITDA measure because these items are non-cash in nature.  Adjusted EBITDA has certain limitations in that it does not take into account the impact to our consolidated statement of operations of certain expenses.

Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by revenue.  We believe Adjusted EBITDA margin is useful for analysts and investors as this measure allows a more meaningful comparison between our performance and that of our competitors.  Adjusted EBITDA margin has certain limitations in that it does not take into account the impact to our consolidated statement of operations of certain expenses.

Free Cash Flow is defined as net cash provided by operating activities, less capital expenditures.  We believe Free Cash Flow is useful to investors because it represents the cash that our operating businesses generate, before taking into account non-operational cash movements.  Free Cash Flow has certain limitations in that it does not represent the total increase or decrease in the cash balance for the period, nor does it represent the residual cash flow for discretionary expenditures.  For example, it does not take into account stock repurchases.  Therefore, we think it is important to evaluate Free Cash Flow along with our consolidated statement of cash flows.

IAC PRINCIPLES OF FINANCIAL REPORTING - continued

Non-Cash Expenses That Are Excluded From Our Non-GAAP Measures

Stock-based compensation expense consists principally of expense associated with the grants, including unvested grants assumed in acquisitions (including the combination of HomeAdvisor and Angie’s List) of stock options, RSUs, performance-based RSUs and market-based awards.  These expenses are not paid in cash and we view the economic cost of stock-based awards to be the dilution to our share base; we also include the related shares in our fully diluted shares outstanding for GAAP earnings per share using the treasury stock method.  Performance-based RSUs and market-based awards are included only to the extent the applicable performance or market condition(s) have been met (assuming the end of the reporting period is the end of the contingency period).  To the extent that stock-based awards are settled on a net basis, the Company remits the required tax-withholding amounts from its current funds.

Please see page 10 for a summary of our dilutive securities, including stock-based awards as of February 1, 2019 and a description of the calculation methodology.

Depreciation is a non-cash expense relating to our property and equipment and is computed using the straight-line method to allocate the cost of depreciable assets to operations over their estimated useful lives, or, in the case of leasehold improvements, the lease term, if shorter.

Amortization of intangible assets and impairments of goodwill and intangible assets are non-cash expenses related primarily to acquisitions (including the combination of HomeAdvisor and Angie’s List).  At the time of an acquisition, the identifiable definite-lived intangible assets of the acquired company, such as technology, service professional and contractor relationships, customer lists and user base, memberships, trade names and content, are valued and amortized over their estimated lives.  Value is also assigned to acquired indefinite-lived intangible assets, which comprise trade names and trademarks, and goodwill that are not subject to amortization.  An impairment is recorded when the carrying value of an intangible asset or goodwill exceeds its fair value.  We believe that intangible assets represent costs incurred by the acquired company to build value prior to acquisition and the related amortization and impairment charges of intangible assets or goodwill, if applicable, are not ongoing costs of doing business.

Gains and losses recognized on changes in the fair value of contingent consideration arrangements are accounting adjustments to report contingent consideration liabilities at fair value.  These adjustments can be highly variable and are excluded from our assessment of performance because they are considered non-operational in nature and, therefore, are not indicative of current or future performance or the ongoing cost of doing business.
