Exhibit 99.1 Alaska Communications Systems Provides Strategic Initiative Updates ANCHORAGE, Alaska--(BUSINESS WIRE)--April 4, 2005--Alaska Communications Systems Group, Inc. ("ACS") (Nasdaq:ALSK) today reviewed progress of its strategic initiatives. As previously announced, as part of its 2005 plan, management has formed process improvement teams to identify areas for operating efficiencies. The teams range from those improving the customer experience in retail stores to reducing costs of high-speed data installations by hundreds of dollars. If ACS is successful in its process improvements, it could achieve $3 million to $4 million in benefits over the next two to three years. These savings are expected to be partially offset by marketing and sales investments to support such activities as further development of bundles and programs to decrease customer churn. For example, management expects to increase media marketing to approximately $4.2 million in 2005 compared to $3.4 million in 2004. ACS is also working to grow its wholesale carrier business through the securing of contracts with interexchange carriers such as MCI and Sprint for their traffic moving to/from Alaska. ACS' existing network and indefeasible rights of use (IRU) commitments provide sufficient capacity to serve any such wholesale contracts that ACS may win. Additionally, having already been granted competitive eligible telecommunication carrier (CETC) status in two separate phases, which is expected to generate approximately $7 million in annual revenue, the company is also contemplating a third phase. If achieved, phase three could add up to $1 million annually in revenue and earnings before taxes, depreciation and amortization. These actions are consistent with and do not alter previously issued guidance. About Alaska Communications Systems ACS is the leading integrated communications provider in Alaska, offering local telephone service, wireless, long distance, data, and Internet services to business and residential customers throughout Alaska.
