NYMEX Files Registration Statement

Fri Feb 23 2007

NEW YORK, NY, February 23, 2007 — NYMEX Holdings, Inc. (NYMEX), (NYSE: NMX), the parent company of the New York Mercantile Exchange, Inc., announced today that it has filed an automatic shelf registration statement on Form S-3 with the Securities and Exchange Commission.

NYMEX is considering a proposed secondary offering of shares of common stock issuable upon conversion of shares of Class A-1, A-2 and A-3 and Class B-1, B-2 and B-3 common stock of NYMEX. NYMEX's charter currently provides for transfer restrictions on the shares of the Class A-1, A-2 and A-3 and Class B-1, B-2 and B-3 common stock. The number of shares to be included in the proposed secondary offering would depend on the interest of the NYMEX stockholders participating in the proposed secondary offering, which will be determined on or about March 7, 2007.

There can be no assurance that NYMEX will pursue or consummate the proposed secondary offering at this time or at any time in the future.

Separately, NYMEX's board of directors is currently considering the adoption of a dividend policy. We expect that the declaration of any dividends, which in any event would not occur until after June 30, 2007, would be based on, among other things, NYMEX's continuing profitability and strategic and operating needs. As a result, there can be no assurance that future dividends will be paid, or if paid will be comparable with past dividends. From 2002 until NYMEX's initial public offering, NYMEX paid cash dividends at least twice per year.
