Decrease in Number of Shares of Class A Common Stock Offered

The aggregate number of shares of BGC Partners, Inc. Class A common stock, par value $0.01 per share, which we refer to as the “Class A common stock,” offered has been reduced by 16,000,000 shares.

BGC Partners, Inc., which we refer to as “BGC Partners,” and/or Cantor Fitzgerald, L.P., which we refer to as “Cantor,” as a selling stockholder, at BGC Partners’ election, have granted the underwriters the right to purchase up to 3,000,000 additional shares of Class A common stock.

Use of Proceeds

BGC Partners estimates that its net proceeds from this offering will be approximately $74,100,000 ($97,260,000 if the underwriters exercise their option to purchase additional shares in full (assuming all of the option shares are sold by BGC Partners)), assuming a public offering price of $8.00 per share, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by BGC Partners.
