NYSE Group Announces Fourth Quarter and Full Year 2006 Financial Results.

NEW YORK -- NYSE Group, Inc. (NYSE: NYX) today reported net income of $45.5 million, or $0.29 per diluted share, for the three months ended December 31, 2006, a $65.8 million increase as compared to a $20.3 million loss, or $(0.18) per diluted share, for the three months ended December 31, 2005. These results are presented in accordance with U.S. Generally Accepted Accounting Principles (GAAP).

Fourth quarter 2006 results include the quarterly results from the operations of NYSE Arca (formerly known as the Archipelago Exchange, or ArcaEx[R], and the Pacific Exchange, Inc.). The merger between NYSE, Inc. and Archipelago Holdings, Inc. closed on March 7, 2006. Fiscal 2005 results include only the operations of New York Stock Exchange, Inc., the predecessor of NYSE Group.

Included in the fourth quarter 2006 results are $34.1 million in merger expenses and exit costs consisting of a restructuring charge in connection with a workforce reduction of more than 500 positions ($29.2 million), the acceleration of certain fixed asset useful lives ($2.8 million), and other professional fees incurred in connection with both the acquisition of Archipelago Holdings, Inc. and the pending combination with Euronext N.V. ($2.1 million).

On a non-GAAP basis, giving effect to the Archipelago transaction as if it occurred at the beginning of the earliest period presented, and excluding the merger expenses and exit costs, the net income of NYSE Group for the three months ended December 31, 2006 would have been $70.8 million, or $0.45 per diluted share, a $65.7 million or twelve-fold increase as compared to net income, on a non-GAAP basis, of $5.1 million, or $0.03 per diluted share, for the three months ended December 31, 2005. A full reconciliation of these non-GAAP results is included in the attached tables.

For the year ended December 31, 2006, net income and diluted earnings per share on a GAAP basis were $205.0 million and $1.36, respectively. This compares to GAAP net income and diluted earnings per share of $40.7 million and $0.35, respectively, for the year ended December 31, 2005. On a non-GAAP basis, net income increased 188% to $258.8 million, while diluted earnings per share increased 193% to $1.64.

"NYSE Group experienced an extraordinary year in 2006. Beginning with the close of the Archipelago transaction and subsequent secondary offering which established the NYSE Group as a public company, we are successfully transforming the NYSE," said NYSE Group Chief Financial Officer and Executive Vice President, Nelson Chai. "Among other things, we have revamped our transaction pricing, restructured the profile of our business portfolio, including through the implementation of the Hybrid Market and taking full control of our technology expenses as a result of our 100% ownership of SIAC, announced the NASD Regulation transaction, and launched our new options platform. We are delivering against the integration savings previously announced in conjunction with the Archipelago transaction, including a 35% reduction in our workforce. Finally, the pending combination with Euronext will create the first true global exchange group. We have executed against an ambitious set of objectives and positioned NYSE Group for long-term growth while delivering substantial shareholder value.

"Our recently announced agreement to acquire 5% of the National Stock Exchange, India's largest financial marketplace, and our strategic alliance with the Tokyo Stock Exchange are a strong start to the new year. In 2007, we will finalize the roll out of our Hybrid Market, deliver against the integration targets in conjunction with the Archipelago transaction and complete the Euronext transaction. We will continue to improve our business model and lead the global transformation of the exchange landscape in order to benefit our investors, listed companies

and market professionals."

To supplement NYSE Group's consolidated financial statements prepared in accordance with GAAP and to better reflect period-over-period comparisons, NYSE Group uses non-GAAP financial measures of operating performance. A non-GAAP financial measure is a numerical measure of performance, financial position, or cash flows that either excludes or includes 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 and exit costs, compensation charges, gains on sale of businesses and other investments, and (ii) improve overall understanding of NYSE Group's current financial performance and its prospects for the future. Specifically, NYSE Group 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.
