LEGAL DISCLAIMERS

Filed by NYSE Euronext
pursuant to Rule 425 under the Securities Act of 1933
and deemed filed pursuant to Rule 14a-12
under the Securities Exchange Act of 1934
Subject Company: NYSE Euronext
Commission File No.: 001-33392
Non-GAAP Financial Measures
To supplement NYSE Euronext’s consolidated financial statements prepared in accordance with GAAP and to better reflect period-over-period comparisons, NYSE Euronext uses
non-GAAP financial measures of performance, financial position, or cash flows that either exclude or include amounts that are not normally excluded or included in the most
directly comparable measure, calculated and presented in accordance with GAAP.  Non-GAAP financial measures do not replace and are not superior to the presentation of GAAP
financial results, but are provided to (i) present the effects of certain merger expenses, exit costs, charge for fair value adjustment to RSU awards, disposal activities, the BlueNext
tax settlement, debt refinancing costs and discrete tax items, and (ii) improve overall understanding of NYSE Euronext’s current financial performance and its prospects for the
future.  Specifically, NYSE Euronext believes the non-GAAP financial results provide useful information to both management and investors regarding certain additional financial
and business trends relating to financial condition and operating results.  In addition, management uses these measures for reviewing financial results and evaluating financial
performance.  The non-GAAP adjustments for all periods presented are based upon information and assumptions available as of the date of this release.
CAUTIONARY STATEMENT REGARDING FORWARD LOOKING STATEMENTS
This communication 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 and NYSE Euronext caution 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 proposed merger involving ICE and NYSE Euronext, including future financial
results, ICE’s and NYSE Euronext’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 and NYSE
Euronext’s filings with the U.S. Securities and Exchange Commission (the “SEC”). These risks and uncertainties include, without limitation, the following: the inability to close the
merger in a timely manner; the inability to complete the merger due to the failure of NYSE Euronext stockholders to adopt the merger agreement or the failure of ICE
stockholders to approve the issuance of ICE common stock in connection with the merger; the failure to satisfy other 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 NYSE Euronext’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, NYSE Euronext’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 the combined
company, as are described in the section entitled “Risk Factors” in the joint proxy statement/prospectus filed by ICE with the SEC, and as described in ICE’s and NYSE Euronext’s
respective 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, 2012, as filed with the SEC on February 6, 2013, and “Risk Factors” in NYSE Euronext’s Form 10-K for the fiscal year ended December 31, 2012, as filed with
the SEC on February 26, 2013.  You should not place undue reliance on forward-looking statements, which speak only as of the date of this written communication. Except for any
obligations to disclose material information under the Federal securities laws, neither ICE nor NYSE Euronext undertakes any obligation to publicly update any forward-looking
statements to reflect events or circumstances after the date of this written communication.
