Item 5.04 Temporary Suspension of Trading under Registrant’s Employee Benefit Plans

On March 17, 2025, in connection with the planned spin-off of Angi Inc. (the “Spin-off”), IAC Inc. (“IAC” or the “Company”) delivered a notice under Rule 104(b)(2)(i) of Regulation BTR to its executive officers and directors (collectively, the “Covered Persons”), regarding a “blackout” period under the IAC Inc. Retirement Savings Plan (the “Plan”) that will be imposed in accordance with Section 306(a) of the Sarbanes-Oxley Act of 2002 and U.S. Securities and Exchange Commission regulations.

The blackout period is expected to begin at 4:00 PM Eastern Time on March 31, 2025 and to end no later than 9:30 AM Eastern Time on April 3, 2025. During the blackout period, participants will be temporarily unable to execute transactions under the Plan involving their balances (if any) in the IAC stock fund, including investment transactions and plan loans and withdrawals. The blackout period under the Plan is needed in connection with the Spin-off in order to allow for the establishment of a new Angi Inc. (“Angi”) stock fund to hold shares of Angi stock received by Plan participant accounts in respect of shares of IAC stock held in the IAC stock fund.

The blackout notice is filed herewith as Exhibit 99.1.
