Item 8.01. Other Items.

        In a press release dated December 15, 2006, AXT, Inc. announced the pricing at $4.50 per share of 5,750,000 shares of its common stock in a firmly underwritten public offering. The amount of shares reflects an increase of 1,600,000 shares over the amount of shares anticipated to be sold as announced in a press release from AXT incorporated by reference into a Current Report on Form 8-K filed on November 30, 2006. The amount of shares also excludes an option that AXT has granted to the sole underwriter to purchase an additional 862,500 shares to cover over-allotments, if any, at any time on or prior to January 13, 2007. AXT estimates the net proceeds to it from the offering will be approximately $24.2 million, or approximately $27.9 million if the underwriter exercises its over-allotment option in full, after payment of the underwriting discount and estimated expenses of this offering, and anticipates that the offering will close on December 19, 2006. Additional details regarding the public offering are contained in the press release, a copy of which is attached hereto as Exhibit 99.1 and which is incorporated herein by reference.

        The Underwriting Agreement dated October 14, 2006 by and between AXT, Inc. and Needham & Company, LLC is attached hereto as Exhibit 1.1, is incorporated herein by reference and is an identically numbered exhibit to both AXT's prospectus dated August 3, 2006 for its registration statement on Form S-3 and AXT's registration statement on S-3MEF dated December 15, 2006.
