Item 8.01 Other Events.

As previously disclosed, on October 26, 2015, Intercontinental Exchange, Inc., a Delaware corporation (“ICE”), Red Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of ICE (“Merger Sub”), Interactive Data Holdings Corporation, a Delaware corporation (“Interactive Data”), and Igloo Manager Co-Invest, LLC, a Delaware limited liability company, solely in its capacity as agent and attorney-in-fact for the Interactive Data stockholders and optionholders, entered into an Agreement and Plan of Merger providing for the acquisition of Interactive Data by ICE through a merger of Merger Sub with and into Interactive Data, with Interactive Data surviving the merger as a wholly owned subsidiary of ICE (the “Merger”). The completion of the Merger is subject, among other conditions, to the expiration or termination of the waiting period applicable to the Merger pursuant to the requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and the rules promulgated thereunder.

ICE filed the notification and report forms required pursuant to the HSR Act in connection with the Merger on November 2, 2015. On November 6, 2015, ICE was notified that the waiting period under the HSR Act applicable to the Merger was terminated by the Federal Trade Commission, and, as a result, the corresponding condition to the parties’ obligation to consummate the Merger has been satisfied. The Merger remains subject to satisfaction of other customary closing conditions and obtainment of approval from the Financial Conduct Authority of the United Kingdom.

CAUTIONARY STATEMENT REGARDING FORWARD LOOKING STATEMENTS

This Current Report on Form 8-K contains “forward-looking statements” made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. In some cases, you can identify forward-looking statements by words such as “may,” “hope,” “will,” “should,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “predict,” “potential,” “continue,” “could,” “future” or the negative of those terms or other words of similar meaning. You should carefully read forward-looking statements, including statements that contain these words, because they discuss our future expectations or state other “forward-looking” information. Forward-looking statements are subject to numerous assumptions, risks and uncertainties which change over time. ICE cautions readers that any forward-looking statement is not a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking statement.

Forward-looking statements include, but are not limited to, statements about the benefits of the Merger involving ICE and Interactive Data, including future financial results, ICE’s plans, objectives, expectations and intentions, the expected timing of completion of the transaction and other statements that are not historical facts. Important factors that could cause actual results to differ materially from those indicated by such forward-looking statements are set forth in ICE’s filings with the SEC. These risks and uncertainties include, without limitation, the following: the inability to close the Merger in a timely manner; the failure to satisfy conditions to completion of the Merger, including receipt of required regulatory and other approvals; the failure of the proposed transaction to close for any other reason; the possibility that any of the anticipated benefits of the proposed transaction will not be realized; the risk that integration of Interactive Data’s operations with those of ICE will be materially delayed or will be more costly or difficult than expected; the challenges of integrating and retaining key employees; the effect of the announcement of the transaction on ICE’s or the combined company’s respective business relationships, operating results and business generally; the possibility that the anticipated synergies and cost savings of the Merger will not be realized, or will not be realized within the expected time period; the possibility that the Merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events; diversion of management’s attention from ongoing business operations and opportunities; general competitive, economic, political and market conditions and fluctuations; actions taken or conditions imposed by the United States and foreign governments or regulatory authorities; and adverse outcomes of pending or threatened litigation or government investigations. In addition, you should carefully consider the risks and uncertainties and other factors that may affect future results of ICE, as described in ICE’s filings with the SEC that are available on the SEC’s web site located at www.sec.gov, including the sections entitled “Risk Factors” in ICE’s Form 10–K for the fiscal year ended December 31, 2014, as filed with the SEC on February 5, 2015, and ICE’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2015, June 30, 2015 and September 30, 2015, as filed with the SEC on May 5, 2015, August 5, 2015 and October 28, 2015, respectively. You should not place undue reliance on forward-looking statements, which speak only as of the date of this Current Report on Form 8-K. Except for any obligations to disclose material information under the Federal securities laws, ICE undertakes no obligation to publicly update any forward-looking statements to reflect events or circumstances after the date of this Current Report on Form 8-K.
