ITEM 2.02    RESULTS OF OPERATIONS AND FINANCIAL CONDITION

        On January 19, 2005, Alaska Communications Systems Group, Inc. (the "Company") announced an update to previously provided guidance for the quarter ended December 31, 2004. The press release is attached hereto as Exhibit 99.1.

ITEM 7.01    REGULATION FD DISCLOSURE

        On January 19, 2005, the Company announced that revenues for the quarter ended December 31, 2004 are expected to be between $74.5 million and $75.0 million, and confirmed that the Company is expected to be within its previously announced quarterly guidance for EBITDA. The Company's expected revenues for the quarter ended December 31, 2004 do not include revenues associated with a significant customer premise equipment contract which the Company had expected to recognize during the quarter. The delay in the Company's ability to recognize revenue relates to issues with the Company's sub-contractor. At this point, however, the sub-contractor is providing the Company with the additional contractors needed. As a result, the Company expects that it will recognize $1.6 million of revenue associated with this contract during the quarter ended March 31, 2005.

        In addition, during the quarter ended December 31, 2004 the Company:


        Including the effect of the foregoing, the Company's cash balance as of December 31, 2004 is expected to be approximately $90.5 million, including approximately $4.7 million of restricted cash.

        The Company's fiscal year ended December 31, 2004. The Company's final results are not yet available and the above information is preliminary and is subject in all respects to completion of various internal analyses and procedures necessary to finalize the Company's financial statements and to the completion of the audit for the fiscal year ended December 31, 2004.

ITEM 8.01    OTHER EVENTS

        On January 18, 2004, the Company filed a preliminary prospectus supplement relating to a proposed offering of its common stock. The proposed offering is expected to raise approximately $75 million of gross proceeds and is part of the Company's previously announced refinancing plan (the "Refinancing Plan"). The preliminary prospectus has been filed with the Securities and Exchange Commission. Excerpts from the preliminary prospectus are included in Exhibit 99.2, which is incorporated by reference herein.

        On January 12, 2004, as part of the Company's Refinancing Plan, the Company's subsidiary, Alaska Communications Systems Holdings, Inc. ("ACSH") commenced tender offers and consent solicitations in respect of its outstanding 97/8% senior subordinated notes due 2009 and its 93/8% senior notes due 2011. A press release relating to these tender offers and consent solicitations is included as Exhibit 99.3 and is incorporated by reference herein.
