Report of Independent Registered Public Accounting Firm

The Administrative Committee
IAC/InterActiveCorp Retirement Savings Plan

        We have audited the accompanying statements of net assets available for benefits of the IAC/InterActiveCorp Retirement Savings Plan (the "Plan") as of December 31, 2011 and 2010, and the related statement of changes in net assets available for benefits for the year ended December 31, 2011. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits.

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Plan's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2011 and 2010, and the changes in its net assets available for benefits for the year ended December 31, 2011, in conformity with U.S. generally accepted accounting principles.

        Our audits were conducted for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at year end) as of December 31, 2011 is presented for purposes of additional analysis and is not a required part of the financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. Such information is the responsibility of the Plan's management. The information has been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole.

IAC/InterActiveCorp Retirement Savings Plan

Notes to Financial Statements

1. Description of the Plan

        The following description of the IAC/InterActiveCorp Retirement Savings Plan (the "Plan") provides only general information. Participants should refer to the Summary Plan Description ("SPD") for a more complete description of the Plan's provisions.

General

        The Plan is a defined contribution plan covering substantially all employees of IAC/InterActiveCorp ("IAC" or the "Company") and certain affiliated companies. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA").

Contributions

        Participants can make pre-tax contributions and/or Roth 401(k) contributions ranging from 1% to 50%, and after-tax contributions ranging from 1% to 10%, in each case, of their compensation (as defined in the Plan document) through payroll deductions. Participant contributions are subject to the annual limitation established by the Internal Revenue Service ("IRS"). For 2011, the IRS limited the annual tax-deferred contribution to $16,500 for each participant. The Plan allows participants age 50 or older to make additional tax-deferred catch up contributions. For 2011, the IRS limited these annual catch up contributions to $5,500 for each participant. Other IRS limits exist for certain highly compensated employees participating in the Plan. The Plan permits rollover contributions from other qualified plans; however, rollover contributions are not eligible for the Company matching contribution. Participants can direct their contributions to any of the Plan's investment options and may generally change their investment options on a daily basis. Participants 18 years of age or older are eligible to participate upon commencement of service (as defined in the Plan document).

        All newly hired employees of the Company are automatically enrolled in the Plan, with pre-tax contributions of 4% (3% prior to July 1, 2011) directed into the various Alliance Bernstein Retirement Stock Funds based on their expected year of retirement commencing approximately 90 days after the date of their first paycheck. Newly hired employees are notified of their automatic enrollment in advance and may elect to change their investment option, contribution percentage or not to participate in the Plan prior to the first automatic deferral.

        The Company contributes an amount equal to 50% of the first 6% of compensation that a participant contributes in each payroll period to the Plan. The Company may also make a discretionary contribution of funds annually, which, if applicable, would be determined by the Company's Board of Directors (or a Committee thereof). For the year ended December 31, 2011, the Company made discretionary contributions of $346,706 to the Plan. The discretionary contributions were made by the Company as some participants elected to make their own contributions at a pace that did not allow them to maximize the full benefit of the Company match. Company matching contributions and discretionary contributions are directed to the investment options of the Plan based upon the respective participant's investment election.

Participant Accounts and Allocations

        Each participant's account is credited with the participant's contribution, the Company's matching contribution and the Company's discretionary contribution, if any, as well as an allocation of Plan earnings (losses). Allocations of Plan earnings (losses) are based on participant account balances in relation to total fund account balances, as defined in the Plan document. Fees charged for participant

loans and distributions are allocated directly to that participant's account. The benefit to which each participant is entitled is the vested portion of each such participant's account.

Vesting

        Participant contributions are fully vested at the time of contribution. Generally, participants are 100% vested in the Company matching contributions (plus actual earnings thereon) after two years of credited service. Certain participants who were employees in plans that were merged into the Plan have different vesting periods for Company matching contributions. In these cases, participants should refer to the applicable merged Plan documents for a complete description of vesting provisions.

Forfeitures

        Company matching contributions that do not vest become forfeitures. Forfeitures are first made available to reinstate previously forfeited account balances of qualifying participants who have left the Company and have subsequently returned, in accordance with applicable law. Remaining amounts, if any, are used to reduce prospective Company matching contributions and discretionary contributions, to fund corrective action necessary to remedy the failure of non-discrimination testing and to pay Plan expenses. Cumulative forfeited non-vested accounts totaled $271,226 and $270,895 at December 31, 2011 and 2010, respectively. The amount of forfeitures used to reduce Company matching contributions totaled $363,475 for the year ended December 31, 2011. The amount of forfeitures used to reduce the employer contributions receivable at December 31, 2011 totaled $279,322.

Notes Receivable from Participants

        Generally, participants may borrow from their accounts a minimum of $1,000, up to a maximum amount equal to the lesser of $50,000 or 50% of their vested account balance. With the exception of loans used to purchase a primary residence, which can have terms of up to 15 years, loan terms are limited to a maximum of five years. Any loans that have been transferred into the Plan from a previous plan are subject to the initial terms of the loan. Loans are secured by the balance in the participant's account and bear interest at a rate commensurate with commercial prevailing rates as determined by the Plan Administrator. Principal and interest are paid ratably through regular payroll deductions. Upon termination of employment, any outstanding loans are due and payable within 90 days following the termination date. Interest rates on outstanding loans range from 4.25% to 9.25%, with maturity dates through June 29, 2026.

Payment of Benefits

        Upon retirement, termination of employment, death, disability, financial hardship or attainment of age 59¹/2, participant vested accounts are distributable in the form of a lump sum payment or substantially equal installments of cash as elected by the participant. Participant vested account balances of more than $5,000 may be left in the Plan as elected by the participant. Participant distributions may not be deferred past April 1 of the calendar year following the year in which the participant attains age 70¹/2. Participant vested account balances of less than $5,000 but more than $1,000 may be automatically rolled over into an individual retirement account ("IRA") unless the participant elects otherwise. Participant vested account balances of $1,000 or less will be automatically distributed in a lump sum. Participants reaching the age of 59¹/2 may elect to withdraw some or all of

their vested account balance while still employed. Participants' pre-tax contributions may be withdrawn earlier, subject to certain hardship withdrawal provisions of the Plan. Generally, participants who have made after-tax contributions may elect to withdraw some or all of their vested account balance with no limit on the number of withdrawals of this type.

Plan Termination

        Although the Company has expressed no intent to terminate the Plan, in the event that the Plan is terminated by the Company, all amounts credited to the participants' accounts would become 100% vested and the net assets would be distributed to participants.

Administrative Expenses

        Substantially all of the administrative expenses are borne by the Plan unless the Company elects to pay such expenses.

2. Summary of Significant Accounting Policies

Basis of Accounting

        The accompanying financial statements have been prepared on the accrual basis of accounting.

        The Plan holds shares of a common collective trust that has investments in fully benefit-responsive investment contracts. These investment contracts are required to be reported at fair value. However, contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. The accompanying statements of net assets available for benefits present the fair value of the investment as well as the adjustment of the investment in the common collective trust fund from fair value to contract value related to fully benefit-responsive investment contracts. The accompanying statement of changes in net assets available for benefits is prepared on a contract value basis.

Use of Estimates

        The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates, judgments and assumptions that affect amounts reported in the financial statements and the accompanying notes. Actual results could differ from those estimates.

Investment Valuation and Income (Loss) Recognition

        The Plan's investments are stated at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. See Note 4 for a discussion of fair value measurements.

        Purchases and sales of investments are recorded on a trade-date basis. Dividend income is recorded on the ex-dividend date and interest income is recorded when earned.

2. Summary of Significant Accounting Policies (Continued)

Notes Receivable from Participants

        Notes receivable from participants are recorded at their unpaid principal balance plus any accrued but unpaid interest. Delinquent participant loans are reclassified as distributions based on the terms of the Plan document. No allowance for credit losses has been recorded as of December 31, 2011 and 2010.

Benefit Payments

        Benefit payments are recorded when paid.

3. Investments

        The Plan's investments (including investments purchased, sold and held during the year) (depreciated) appreciated in fair value as follows:

        The following are investments that represent 5% or more of the Plan's net assets:

4. Fair Value Measurements

        The Plan categorizes its assets and liabilities 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 prices for identical assets and liabilities in active markets.

7

---

IAC/InterActiveCorp Retirement Savings Plan

Notes to Financial Statements (Continued)

4. Fair Value Measurements (Continued)

•

Level 2:    Other inputs that are observable directly or indirectly, such as quoted prices for similar assets or liabilities in active markets, quoted 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.



•

Level 3:    Unobservable inputs for which there is little or no market data and require the Plan 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 shares of registered investment companies, the self-directed brokerage account (which invests primarily in common stocks, cash equivalents and registered investment companies) and the IAC/InterActiveCorp common stock fund are valued at quoted market prices at year end. The fair value of the common collective trust fund is based on the net asset value ("NAV") reported by the administrator of the Schwab Stable Value Fund. The NAV is based on the value of the underlying assets owned by the fund, minus its liabilities, and then divided by the number of shares outstanding. There have been no changes in the valuation methodologies used at December 31, 2011 and 2010.

        The preceding valuation methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while management believes the valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

        The following tables present the Plan's assets that are measured at fair value on a recurring basis. There are no Plan assets that are measured on a recurring basis using Level 3 inputs.

5. Income Tax Status

        The Plan received a determination letter from the IRS dated October 5, 2011, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the "Code") and, therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan Administrator believes that the Plan conforms to ERISA requirements and continues to qualify as tax exempt under the Code. Accordingly, no provision for income taxes has been included in the Plan's financial statements.

        Accounting principles generally accepted in the United States require Plan management to evaluate uncertain tax positions taken by the Plan. The financial statement effects of a tax position are recognized when the position is more likely than not, based on the technical merits, to be sustained upon examination by the IRS. The Plan Administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2011, there are no uncertain tax positions taken or expected to be taken. The Plan has recognized no interest or penalties related to uncertain tax positions. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan Administrator believes it is no longer subject to income tax examinations for years prior to 2008.

6. Transfers to Other Plans

        On December 1, 2010, IAC exchanged (on a tax-free basis) the stock of a wholly-owned subsidiary that held the Company's Evite, Gifts.com and IAC Advertising Solutions businesses and $217.9 million in cash for substantially all of Liberty Media Corporation's ("Liberty") equity stake in IAC. As a result of this transaction and pursuant to a Transition Service Agreement, dated December 1, 2010, between

Notes to Financial Statements (Continued)

6. Transfers to Other Plans (Continued)

the Company and Liberty, the Plan continued to cover substantially all employees of Evite, Gifts.com and IAC Advertising Solutions until June 1, 2011, after which the net assets available for benefits of the employees of these businesses were transferred out of the Plan to a separately established plan maintained by Liberty.

        On January 31, 2011, IAC contributed The Daily Beast to a newly formed venture with Harman Newsweek called The Newsweek/Daily Beast Company. IAC and Harman Newsweek operate The Newsweek/Daily Beast Company jointly. As a result of this transaction the net assets available for benefits of the employees of The Daily Beast were transferred out of the Plan on June 1, 2011.

7. Related-Party Transactions

        Certain Plan investments consist of common stock of IAC, the Plan sponsor, and shares of registered investment companies and a common collective trust managed by Schwab Retirement Plan Services, Inc., the Plan's record keeper. Therefore, these transactions qualify as party-in-interest transactions. Fees paid by the Plan for the recordkeeping and administrative services amounted to $56,164 for the year ended December 31, 2011.

8. Certain Risks and Uncertainties

        The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the statements of net assets available for benefits.

9. Reconciliation of Financial Statements to Form 5500

        The following is a reconciliation of the statements of net assets available for benefits between the financial statements and Form 5500:

10. Subsequent Event

        After a review of Plan investments by the Company, effective March 30, 2012 and May 15, 2012, various investment options under the Plan were changed to better align to the investment guidelines of the Plan.
