SUMMARY RESULTS

($ in millions except per share amounts)

See reconciliations of GAAP to non-GAAP measures beginning on page 10.

·                  Consolidated revenue increased 4% year-over-year in the first quarter driven by solid growth at The Match Group, Media and eCommerce, partially offset by modest declines at Search & Applications.

·                  The Match Group revenue increased 13%, or 19% excluding the effects of foreign exchange, driven by contributions from The Princeton Review and FriendScout24, acquired on August 1, 2014 and August 31, 2014, respectively, and 16% growth in Dating paid subscribers to over 4.0 million globally.  Dating revenue increased 2%, or 8% excluding the effects of foreign exchange.

·                  Search & Applications revenue decreased 4% driven by 7% and 1% declines at Websites and Applications, respectively.

·                  Consolidated Adjusted EBITDA decreased 30% year-over-year in the first quarter driven by increased investment at The Match Group, Media and eCommerce and lower revenue at Search & Applications, partially offset by lower Corporate expenses.

·                  IAC repurchased 3.0 million shares of common stock between February 3, 2015 and April 24, 2015 at an average price of $67.68 per share, or $200.0 million in aggregate.

DISCUSSION OF FINANCIAL AND OPERATING RESULTS

Search & Applications

Websites revenue decreased 7% due primarily to a decline in revenue at Ask.com, partially offset by strong growth at About.com.  Applications revenue decreased 1% due to lower queries in B2B (our partnership operations), partially offset by strength in our B2C business, including query growth in our desktop search applications, as well as the contribution from mobile applications (via our acquisition of Apalon on November 3, 2014) and SlimWare (acquired April 1, 2014).  Adjusted EBITDA decreased 4% due primarily to the lower revenue and the impact of the write-off of $2.3 million of deferred revenue in connection with the acquisition of SlimWare.  Operating income decreased 9% as the current year period was negatively impacted by a $4.0 million contingent consideration fair value adjustment.

The Match Group

Dating revenue grew 2% due primarily to 8% growth in North America driven by increased paid subscribers, partially offset by 8% lower International revenue due to foreign exchange effects, despite an increase in paid subscribers.  Excluding foreign exchange effects, total Dating revenue would have increased 8% and International revenue would have increased 9%.  Non-dating(1) revenue, which benefited from the acquisition of The Princeton Review, grew 372%.  Adjusted EBITDA decreased 45% due to increased marketing spend at Dating and DailyBurn, losses from The Princeton Review, which was not in the prior year period, $3.3 million of costs in the current year related to the ongoing consolidation and streamlining of our technology systems and European operations at our Dating businesses as well as a $3.9 million benefit in the prior year related to the expiration of the statute of limitations for a non-income tax matter.  Operating income reflects a positive $11.0 million contingent consideration fair value adjustment in the current year period.

Media

Revenue increased 20% due principally to the contribution from IAC Films and solid growth at Vimeo.  The Adjusted EBITDA loss was larger than the prior year due primarily to increased investment in Vimeo.

eCommerce

Revenue increased 13% due to significant growth at HomeAdvisor.  Adjusted EBITDA losses were $3.1 million in the first quarter versus profits in the prior year due primarily to increased investment at HomeAdvisor.

Corporate

The Corporate Adjusted EBITDA loss decreased due primarily to lower compensation costs.  Corporate operating loss reflects an increase of $8.3 million in stock-based compensation expense due primarily to a higher number of forfeited awards in the prior year and the impact of a modification of certain awards in the current year.

OTHER ITEMS

The effective tax rates for continuing operations in Q1 2015 and Q1 2014 were 22% and 38%, respectively, and the effective tax rates for Adjusted Net Income in Q1 2015 and Q1 2014 were 34% and 36%, respectively.  The effective rate for continuing operations was lower in Q1 2015 due primarily to the non-taxable gain on contingent consideration fair value adjustments in the current year.

Note 1: Includes The Princeton Review, Tutor.com and DailyBurn.

IAC’S PRINCIPLES OF FINANCIAL REPORTING

IAC reports Adjusted EBITDA, Adjusted Net Income, Adjusted EPS and Free Cash Flow, all of which are supplemental measures to 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 goodwill and intangible asset impairments and (ii) gains and losses recognized on changes in the fair value of contingent consideration arrangements.  We believe Adjusted EBITDA is a useful measure for analysts and investors as this measure allows a more meaningful comparison between our performance and that of our competitors.  Moreover, our management uses this measure internally to evaluate the performance of our business as a whole and our individual business segments.  The above items are excluded from our Adjusted EBITDA measure because these items are non-cash in nature, and we believe that by excluding these items, Adjusted EBITDA corresponds more closely to the cash operating income generated from our business, from which capital investments are made and debt is serviced.

Adjusted Net Income generally captures all items on the statement of operations that have been, or ultimately will be, settled in cash and is defined as net earnings attributable to IAC shareholders excluding, net of tax effects and noncontrolling interests, if applicable: (1) stock-based compensation expense, (2) acquisition-related items consisting of (i) amortization of intangibles and goodwill and intangible asset impairments and (ii) gains and losses recognized on changes in the fair value of contingent consideration arrangements, (3) income or loss effects related to IAC’s former passive ownership in VUE, and (4) discontinued operations.  We believe Adjusted Net Income is useful to investors because it represents IAC’s consolidated results taking into account depreciation, which management believes is an ongoing cost of doing business, as well as other charges that are not allocated to the operating businesses such as interest expense, income taxes and noncontrolling interests, but excluding the effects of any other non-cash expenses.

Adjusted EPS is defined as Adjusted Net Income divided by fully diluted weighted average shares outstanding for Adjusted EPS purposes.  We include dilution from options and warrants in accordance with the treasury stock method and include all restricted stock units (“RSUs”) in shares outstanding for Adjusted EPS, with performance-based RSUs included based on the number of shares that the Company believes are probable of vesting.  This differs from the GAAP method for including RSUs, which are treated on a treasury method, and performance-based RSUs, which are included for GAAP purposes only to the extent the performance criteria have been met (assuming the end of the reporting period is the end of the contingency period).  Shares outstanding for Adjusted EPS purposes are therefore higher than shares outstanding for GAAP EPS purposes.  We believe Adjusted EPS is useful to investors because it represents, on a per share basis, IAC’s consolidated results, taking into account depreciation, which we believe is an ongoing cost of doing business, as well as other charges, which are not allocated to the operating businesses such as interest expense, income taxes and noncontrolling interests, but excluding the effects of any other non-cash expenses.  Adjusted Net Income and Adjusted EPS have the same limitations as Adjusted EBITDA, and in addition, Adjusted Net Income and Adjusted EPS do not account for IAC’s former passive ownership in VUE.  Therefore, we think it is important to evaluate these measures along with our consolidated statement of operations.

IAC’S PRINCIPLES OF FINANCIAL REPORTING - continued

Free Cash Flow is defined as net cash provided by operating activities, less capital expenditures.  In addition, Free Cash Flow excludes, if applicable, tax payments and refunds related to the sales of certain businesses and investments, including IAC’s interests in VUE, an internal restructuring and dividends received that represent a return of capital due to the exclusion of the proceeds from these sales and dividends from cash provided by operating activities.  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.

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, of stock options, restricted stock units and performance-based RSUs.  These expenses are not paid in cash, and we include the related shares in our fully diluted shares outstanding using the treasury stock method; however, performance-based RSUs are included only to the extent the performance criteria have been met (assuming the end of the reporting period is the end of the contingency period).  We view the true cost of stock options, restricted stock units and performance-based RSUs as the dilution to our share base, and such awards are included in our shares outstanding for Adjusted EPS purposes as described above under the definition of Adjusted EPS.  Upon the exercise of certain stock options and vesting of restricted stock units and performance-based RSUs, the awards are settled, at the Company’s discretion, on a net basis, with the Company remitting the required tax-withholding amount from its current funds.

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.

Amortization of intangible assets and goodwill and intangible asset impairments are non-cash expenses relating primarily to acquisitions.  At the time of an acquisition, the identifiable definite-lived intangible assets of the acquired company, such as content, technology, customer lists, advertiser and supplier relationships, 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.  While it is likely that we will have significant intangible amortization expense as we continue to acquire companies, 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 ongoing costs of doing business.

Income or loss effects related to IAC’s former passive ownership in VUE are excluded from Adjusted Net Income and Adjusted EPS because IAC had no operating control over VUE, which was sold for a gain in 2005, had no way to forecast this business, and did not consider the results of VUE in evaluating the performance of IAC’s businesses.

Free Cash Flow

We look at Free Cash Flow as a measure of the strength and performance of our businesses, not for valuation purposes.  In our view, applying “multiples” to Free Cash Flow is inappropriate because it is subject to timing, seasonality and one-time events.  We manage our business for cash and we think it is of utmost importance to maximize cash — but our primary valuation metrics are Adjusted EBITDA and Adjusted EPS.
