ALASKA COMMUNICATIONS SYSTEMS FILES FOR INITIAL
PUBLIC OFFERING OF INCOME DEPOSIT SECURITIES AND
PUBLIC OFFERING OF SENIOR SUBORDINATED NOTES

Proposes Reclassification of Outstanding Common Stock

        ANCHORAGE, Alaska—April 12, 2004—Alaska Communications Systems Group, Inc. (ACS) (Nasdaq: ALSK) today announced that it has filed a registration statement with the Securities and Exchange Commission (SEC) for the initial public offering of its Income Deposit Securities (IDS) and a separate offering of its senior subordinated notes. An IDS is a unit containing one share of new class A common stock of ACS and a fixed principal amount of senior subordinated notes of ACS. The senior subordinated notes to be sold in the separate offering will be identical to those senior subordinated notes included in the IDSs.

        ACS plans to use the net proceeds of the proposed offerings, together with available cash, to refinance certain outstanding indebtedness and to finance the cash portion of a proposed reclassification of all of ACS's outstanding common stock prior to these offerings, including shares held by affiliates of Fox Paine & Company, LLC, its majority shareholders, into a combination of cash and shares of new class B common stock of ACS. All remaining shares of class B common stock issued in the reclassification will be subject to redemption with the net proceeds of any exercise of the option granted by ACS to the underwriters to purchase additional IDSs from ACS to satisfy overallotments from the initial public offering. All remaining shares of the class B common stock not so redeemed will be exchanged into IDSs, in specified portions and subject to certain conditions, on the 12th day following the completion of the reclassification and on the second anniversary of the reclassification.

        The completion of the proposed offerings and reclassification is subject to a number of conditions, including the approval of the reclassification by the holders of a majority of ACS's outstanding common stock.

        Citigroup Global Markets Inc., CIBC World Markets Corp. and J.P. Morgan Securities Inc. will serve as lead underwriters and joint book-running managers. Banc of America Securities LLC and RBC Capital Markets Corporation will serve as lead managers for the offerings.



        Liane Pelletier, Chair, CEO and President of ACS, commented: "We are pursuing these offerings as we believe that they will improve our overall financial flexibility by increasing our access to capital and strengthening our balance sheet while providing increased value to our existing shareholders. Additionally, we hope to expand our equity investor base through these offerings. We expect the reclassification and the offerings will support our long term strategic and operating plans."

        In connection with the proposed reclassification of ACS's existing common stock, ACS has filed a preliminary information statement/prospectus, included in a registration statement on Form S-4, with the SEC. SECURITY HOLDERS ARE ADVISED TO READ THE INFORMATION STATEMENT/PROSPECTUS (WHEN AVAILABLE), BECAUSE IT WILL CONTAIN IMPORTANT INFORMATION.

Newsbreak to All Employees
April 12, 2004

Dear ACS Employee:

        You may read about a financial recapitalization we are proposing to undertake. With this note, I'll attempt to answer any questions you may have about the potential transaction.

        The proposed recapitalization will have no impact on the daily operations of ACS. The recapitalization is strictly a financial event. This is supportive of the strategic and operational plans that have been communicated to you in recent weeks. The message you can pass on to customers or business associates is that it is business as usual at ACS with our focus squarely on the customer.

        This is an important and natural step for the company. In a nutshell, we expect it will result in a strengthened balance sheet and a more diverse shareholder base. It provides an excellent opportunity to return the company to a wider public ownership.

        We will continue to keep you informed as events unfold and further developments related to the proposed recapitalization become available. Meanwhile, you can find a copy of our public announcement on the company investor site at www.alsk.com.

Liane Pelletier
Chair, CEO and President, ACS
