“Our results in the third quarter reflect the impact of dampened transaction revenue due to slow overall industry volumes,” commented Michael S. Geltzeiler, Group Executive Vice President and CFO, NYSE Euronext. “Despite lackluster near-term volume trends, we are focusing on those areas of our business model that are within our control. We are maintaining market share across our primary venues, we continue to develop additional cylinders of growth with new initiatives and our technology services business, we are continuing to reduce our fixed-cost base and are focused on better managing our capital for the benefit of our shareholders. On a constant dollar, constant portfolio basis, our fixed expenses were down $26 million, or 6% compared to the third quarter of 2009 and we expect to be below the low-end of our full-year fixed cost range.”

THIRD QUARTER 2010 CONSOLIDATED RESULTS

Total revenues less transaction-based expenses (net revenue), which include Section 31 fees, liquidity payments and routing and clearing fees, was $599 million in the third quarter of 2010, down $22 million, or 4% compared to $621 million in the third quarter of 2009. Third quarter 2010 net revenue compared to the third quarter of 2009 included a $25 million negative impact attributable to foreign currency fluctuations. On a currency neutral basis, net revenue in the third quarter of 2010 would have been slightly above third quarter of 2009 levels. The decrease in net revenue compared to the third quarter of 2009 was primarily driven by a $35 million, or 11% decrease in net transaction and clearing revenue, related to European cash and derivatives trading, partially offset by a $23 million, or 39% increase in technology services revenue.

Fixed operating expenses, excluding merger expenses and exit costs, were $419 million, compared to $426 million in the third quarter of 2009. Excluding the impact of acquisitions, a $13 million positive impact attributable to foreign currency fluctuations and investment in new businesses, fixed operating expenses were down $26 million, or 6%, compared to the third quarter of 2009.

Full-year 2010 fixed operating expenses are now expected to be below the low-end of the currency adjusted full-year range of $1,707 million and $1,749 million. The currency adjusted full-year 2010 fixed operating expense range is based on current EUR/USD and GBP/USD currency rates, which derive full-year 2010 average currency rates of EUR/USD $1.34 and GBP/USD $1.55. The original full-year 2010 fixed operating expense range was $1,723 million and $1,768 million and was based on 2009 average foreign currency rates of EUR/USD $1.39 and GBP/USD $1.57.

Operating income, excluding merger expenses and exit costs, was $180 million, down $15 million, or 8% compared to the third quarter of 2009 and included a $12 million negative impact attributable to foreign currency fluctuations. On a

currency neutral basis, operating income in the third quarter of 2010 would have decreased 2% compared to the third quarter of 2009.

Adjusted EBITDA which excludes merger expenses and exit costs, was $249 million, compared to $261 million in the third quarter of 2009. Adjusted EBITDA margin was 42% in the third quarter of 2010, in-line with the third quarter of 2009.

Non-operating income for the third quarter of 2010 includes the impact of the investment in New York Portfolio Clearing (income from associates) and NYSE Liffe U.S. (net loss/income attributable to non-controlling interest) initiatives. Both New York Portfolio Clearing and NYSE Liffe U.S. are currently in a loss position.

The effective tax rate for the third quarter of 2010 was 24.2% compared to 21.7% in the third quarter of 2009. The effective tax rate in the third quarter of 2010 includes the impact of advance tax rulings following the adoption of favorable tax laws in the Netherlands, lowering the estimated full-year effective tax rate from 27.5% to 26.5% which added $0.02 to third quarter 2010 diluted earnings per share. The effective tax rate in the third quarter of 2009 included the favorable impact of an effective tax rate true-up, which added $0.03 to third quarter 2009 diluted earnings per share. The effective tax rate for the Company is projected to be 26.5% for the remainder of 2010.

The weighted average diluted shares outstanding in the third quarter of 2010 was 262 million shares, up from 260 million shares in the third quarter of 2009 and 261 million shares in the second quarter of 2010. The weighted average diluted shares outstanding are projected to be 262 million shares for the remainder of 2010.

At September 30, 2010, total debt declined $0.2 billion from December 31, 2009 to $2.5 billion and consists of $2.1 billion in long-term debt and $0.4 billion in short-term debt. Cash, cash equivalents, investments and other securities (including $23 million related to Section 31 fees collected from market participants and due to the SEC) was $0.4 billion and net debt was $2.1 billion.

Headcount as of September 30, 2010 was 3,030 (including 34 staff from Corporate Board Member) down 10% from December 31, 2009 and down 11% from September 30, 2009.

The Board of Directors declared a cash dividend of $0.30 per share for the fourth quarter of 2010. The fourth quarter 2010 dividend is payable December 31, 2010 to shareholders of record as of the close of business on December 15, 2010. The anticipated ex-date will be December 13, 2010.

•

Derivatives net revenue of $188 million in the third quarter of 2010 decreased $10 million, or 5% compared to the third quarter of 2009 and included a $10 million negative impact from foreign currency fluctuations. These results were primarily driven by a $15 million, or 10% decrease in European derivatives net transaction and clearing revenue, partially offset by a $3 million, or 11% increase in U.S. options trading net transaction and clearing revenue. Derivatives net revenue decreased $38 million, or 17% compared to the second quarter of 2010 and included a $5 million positive impact from foreign currency. These results were primarily due to trading volume declines of 25% and 22% for European (excluding Bclear) and U.S. derivatives, respectively, from elevated second quarter 2010 levels. Adjusting for the impact of foreign currency fluctuations, Derivatives net revenue in the third quarter of 2010 would have been flat compared to the third quarter of 2009 and would have decreased 19% compared to the second quarter of 2010.

•

European derivatives net transaction and clearing revenue of $132 million in the third quarter of 2010 decreased $15 million, or 10% compared to the third quarter of 2009 and included a $9 million negative impact from foreign currency fluctuations. European derivatives trading volumes increased 1% in the third quarter of 2010 compared to the third quarter of 2009. The 10% decrease in European derivatives net transaction and clearing revenue compared to the third quarter of 2009 was primarily driven by an 11% decrease in the average net rate per contract (excluding Bclear) due to the impact of business mix and negative currency fluctuations. European derivatives net transaction and clearing revenue decreased $29 million, or 18% compared to second quarter of 2010 and included a $4 million positive impact from foreign currency fluctuations. These results were due to a 25% decline in trading volumes (excluding Bclear) for the period. Adjusting for the impact of foreign currency fluctuations, net transaction and clearing revenue would have decreased 4% from the third quarter of 2009 and would have decreased 20% from the second quarter of 2010.

•

The average net rate per contract for European derivatives (excluding Bclear), including the impact of currency fluctuations, in the third quarter of 2010 was $0.670 per contract, down from $0.754 per contract in the third quarter of 2009, but up from $0.643 per contract in the second quarter of 2010. On a currency neutral basis, using third quarter 2010 average GBP/USD currency rates, the average net rate per contract in the second quarter of 2010 was $0.668 and the average net rate per contract in the third quarter of 2009 was $0.713.

•

U.S. equity options net transaction revenue of $35 million in the third quarter of 2010 increased $3 million, or 11% compared to the third quarter of 2009, but declined $7 million, or 17% compared to the second quarter of 2010. These results were primarily driven by increases in market share which drove a 24% increase in NYSE Euronext U.S. equity options ADV to 3.2 million contracts, up from 2.6 million contracts in the prior year period, partially offset by a 10% decline in the average rate per contract. The decline in net transaction revenue compared to the second quarter of 2010 was driven by a 22% decline in trading volumes.

•

The average net rate per contract for U.S. equity options in the third quarter of 2010 was $0.171 per contract, down from $0.191 per contract in the third quarter of 2009, but up slightly from the $0.165 per contract recorded in the second quarter of 2010. The decrease in the average net rate per contract compared to the third quarter of 2009 was primarily driven by an increase in penny-pilot issues traded over NYSE Arca. Penny-pilot issues

represented 83% of consolidated U.S. equity options trading volume in the third quarter of 2010, compared to 52% in the third quarter of 2009 and 74% in the second quarter of 2010.

•

NYSE Euronext’s U.S. equity options exchanges accounted for 26% of total consolidated U.S. equity options trading in the third quarter of 2010, up from 20% in the third quarter of 2009 and in-line with 26% in the second quarter of 2010.

•

Operating income, excluding merger expenses and exit costs, in the third quarter of 2010 was $93 million, an 11% decrease compared to $104 million in the third quarter of 2009 and a $47 million, or 34% decrease from the second quarter of 2010.

•

Operating margin, excluding merger expenses and exit costs, was 49%, compared to 53% in the third quarter of 2009 and 62% in the second quarter of 2010. Adjusted EBITDA margin was 57%, compared to 62% in the third quarter of 2009 and 68% in the second quarter of 2010.

•

The CFTC Derivatives Clearing Organization (DCO) filing for New York Portfolio Clearing (NYPC), the innovative joint venture of the Depository Trust & Clearing Corporation (DTCC) and NYSE Euronext, has been submitted and is in the 90-day comment period as of November 1, 2010. NYPC is expected to deliver unique operational and capital efficiencies to the market by evaluating a clearing member’s risk on a portfolio basis across both cash bonds and derivatives.

•

Cash Trading and Listings net revenue was $298 million in the third quarter of 2010, a decrease of $28 million, or 9% compared to the third quarter of 2009 and included a $10 million negative impact from foreign currency fluctuations. These results were primarily driven by a $25 million, or 19% decline in net transaction revenue, principally due to pricing reductions in European cash in 2009 and lower trading volumes in U.S. cash trading. Net revenue decreased $23 million, or 7% compared to the second quarter of 2010 and included a $1 million

positive impact from currency fluctuations. These results were primarily due to trading volume declines of 21% and 25%, respectively, for European and U.S. cash equities trading from elevated second quarter 2010 levels. Adjusting for the impact of foreign currency fluctuations, Cash Trading and Listings net revenue in the third quarter of 2010 would have decreased 6% compared to the third quarter of 2009 and would have decreased 7% compared to the second quarter of 2010.

•

European cash products net transaction revenue of $59 million in the third quarter of 2010 decreased $19 million, or 24% compared to the third quarter of 2009 and included a $6 million negative impact from currency fluctuations. The decline in European cash net transaction revenue compared to the third quarter of 2009 was driven primarily by 2009 pricing changes and the negative impact from currency fluctuations. Net transaction revenue decreased $12 million, or 17% from the second quarter of 2010 and included a $1 million positive impact of currency fluctuations. The decline in net transaction and clearing revenue compared to the second quarter of 2010 was primarily due to a 21% decline in trading volumes for the period. Adjusting for the impact of foreign currency fluctuations, net transaction revenue in the third quarter of 2010 would have decreased 17% compared to the third quarter of 2009 and would have decreased 18% compared to the second quarter of 2010.

•

Average net revenue per transaction for European cash products, including the impact of currency fluctuations, in the third quarter of 2010 was $0.655 per transaction, down from $0.896 per transaction in the third quarter of 2009, but up slightly from $0.654 per transaction in the second quarter of 2010. On a currency neutral basis, using third quarter of 2010 average EUR/USD currency rates, the average net revenue per transaction in the second quarter of 2010 was $0.665 and the average net revenue per transaction in the third quarter of 2009 was $0.808.

•

•

U.S. cash products net transaction revenue of $48 million decreased $6 million, or 11% from $54 million in the third quarter of 2009 and decreased $12 million, or 20% from the second quarter of 2010.

The decrease in U.S. cash products net transaction revenue compared to the second quarter of 2010 was primarily driven by a 25% decrease in U.S. cash trading volume. Total U.S. consolidated cash equities average daily trading volume in the third quarter of 2010 was 7.6 billion shares, the lowest quarterly average daily trading volume since the second quarter of 2008.

The increase in the net rate per 100 shares handled from the third quarter of 2009 was driven by accretive pricing changes on NYSE and NYSE Arca.

Information Services and Technology Solutions revenue was $113 million in the third quarter of 2010, an increase of $19 million, or 20% compared to the third quarter of 2009 and included a $5 million negative impact from foreign currency fluctuations. The increase in revenue compared to the third quarter of 2009 was primarily driven by the impact of the NYFIX acquisition and an increase in global SFTI and software sales revenue. Revenue increased $6 million, or 6% compared to the second quarter of 2010 and included a $1 million positive impact

from foreign currency fluctuations. The increase in revenue compared to the second quarter of 2010 was primarily driven by increases in global SFTI and software sales revenue. Adjusting for the impact of foreign currency fluctuations, Information Services and Technology Solutions revenue in the third quarter of 2010 would have increased 26% compared to the third quarter of 2009 and would have increased 5% compared to the second quarter of 2010.

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 and other special 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.
