NASDAQ OMX Group (NDAQ)

from 15.9% to 21.4% in One-Year Period

New York, N.Y. — The Nasdaq Stock Market, Inc. (NASDAQ^®: NDAQ) today announced its consolidated market performance statistics for the NASDAQ Market Center, INET and Brut trading platforms. NASDAQ expects to make these monthly performance statistics public on the second Monday of each month, and will disclose market statistics available for the first time, including matched and touched market share in NASDAQ and NYSE-listed securities.

During February 2006, NASDAQ continued to maintain strong market share in NASDAQ-listed securities, with total market share of 80.0%, in line with January’s market share of 80.9%. NASDAQ’s total market share in NYSE-listed securities was 21.4% last month, an increase from 15.9% in February 2005.* NASDAQ’s average daily share volume in NYSE-listed securities in February 2006 was 497.4 million, compared to 311.0 million February 2005 and 551.8 million in the previous month. Included in the total market share figure for February is 25.3% in NASDAQ securities and 14.4% in NYSE securities executed by broker dealers and reported to NASDAQ.

“NASDAQ continues to see stable market share in NASDAQ-listed securities. Over the course of 2005 and with the acquisition of INET, we have seen a dramatic increase in our NYSE-listed market share,” commented Chris Concannon, executive vice president of NASDAQ Transaction Services. “The increase in our market share of NYSE-listed securities is being driven by a strong demand for automated executions in NYSE-listed stocks. As a result we have seen our liquidity pool of matched market share in NYSE-listed securities increase to an average of 7% in February and our touched market share in these securities rise from a 3% average in January 2005 to an average of 17.7% in February 2006.”

Our total market share in NASDAQ-listed securities is total share volume of NASDAQ-listed securities that are executed on the NASDAQ Market Center, INET and/or Brut books plus internalized volume, as a percentage of total consolidated NASDAQ market volume. Shares routed to other market centers for execution are not included.
