ALASKA COMMUNICATIONS SYSTEMS REPORTS SECOND QUARTER RESULTS

Successful Offering of Directory Business Results in 2Q Net Income of $92.7 Million

Municipality of Anchorage Approves ACS’ $10.4 Million E911 Proposal

ANCHORAGE, Alaska—Alaska Communications Systems Group, Inc. (“ACS”) (Nasdaq:ALSK) today reported financial results for the second quarter ended June 30, 2003.

Revenues for the second quarter of 2003 increased sequentially to $84.8 million and EBITDA was $29.0 million. This compared to revenues of $92.9 million and EBITDA of $35.9 million for the second quarter of 2002, which included $11.1 million of access revenue as a result of a favorable court ruling related to a dispute. ACS reported net income of $92.7 million, or $3.08 per share for the second quarter of 2003, compared to net income of $3.6 million, or $0.11 per share for the same period in 2002. During the second quarter of 2003, the Company recorded a gain related to the sale of a majority interest in its directories business of approximately $97.6 million.

On May 8, 2003, ACS announced the successful completion of the initial public offering of its directories business. Adjusted for the sale of the directory business, pro forma second quarter revenues were $81.4 million and EBITDA was $27.6 million. This represents a $5.2 million sequential increase in revenues and a $1.8 million increase in EBITDA over the preceding quarter on a pro forma basis.

The Company also announced today that the Anchorage Assembly unanimously approved ACS’ ten-year $10.4 million proposal to upgrade and manage the city’s existing 911 system. The upgrade will include improved network services, improved address and location data, better work stations for dispatchers and enhanced map display equipment for the Anchorage Police Department and the Anchorage Fire Department.

“The second quarter generated strong improvements in our operating and financial results for the Company,” commented Chuck Robinson, Chairman and CEO of ACS. “The successful IPO of our directories business enabled us to pay off over $112 million in debt and increase our cash by over $31 million. Moving forward, we will capitalize on this improved financial position to invest in selected strategic initiatives, like our new innovative service bundling programs introduced this quarter and our advanced CDMA 1X network, offering exciting new customer features and improved coverage rolling out in the second half of the year. We believe these programs will allow us to continue to serve Alaska as the premier telecommunications company offering the most integrated spectrum of services to both consumers and businesses throughout the State.”

“We are pleased with the sequential increase in revenue in the second quarter at each of our business units,” commented Kevin P. Hemenway, Senior Vice President and CFO of ACS. “Most noteworthy was an exceptional performance by our wireless business, with strong revenues, EBITDA, and increasing MOU. Additionally, our local telephone business continued to benefit from the aggressive restructuring program we undertook a year ago, as EBITDA margins were 50.2% for the period. While we continued to experience traditional access line losses as a result of the unbalanced regulatory environment and an erosion of the total number of access lines in the market, this loss of traditional access lines was partially offset by the increase of approximately 6,300 in enterprise telephone lines associated with the State of Alaska. In addition, we made meaningful progress in the operation of the State contract during the quarter as we completed the inventory of units served for the State, resulting in approximately $1.5 million in out-of-quarter revenue and $1.6 million in out-of-quarter costs. The bulk of this labor intensive effort to properly account for the State’s services for which we can bill is now substantially complete, and we expect to see

gradual sequential improvement to EBITDA margins in this segment moving forward, while continuing to address the transformation of the State’s network to our advanced IP platform.”

“During the quarter, we paid off $112.8 million in debt, successfully managed our capital expenditures and, as a result, entered the third quarter with $64.7 million in cash and an available $75 million line of credit,” added Mr. Hemenway. “Additionally, we retain an ownership interest in the directories business currently valued in the market at over $18 million. The successful spin-off of our directories business enabled us to improve our credit profile as our net leverage ratio declined to 4.1x and our interest coverage ratio increased to 2.4x, on a pro forma basis after giving effect to the transaction. With the company’s improved credit profile, we are currently exploring opportunities to raise additional capital to support the future growth of the business and to refinance our senior secured credit facilities with some combination of new senior and senior secured indebtedness.”

Quarter Summary

• Local telephone revenues for the second quarter were up both on a sequential basis and on a normalized basis year-over-year. Due to the effect of the Company’s aggressive cost reduction program, local telephone EBITDA margins increased to 50.2% from 49.1% for the same period last year.

• Access lines ended at 339,397 including 21,169 enterprise telephone lines resulting from the State of Alaska contract. Traditional access lines ended the quarter at 318,228, a sequential decrease of 2,319 as the Company was impacted by the erosion in its access line base from competitive bypass and the elimination of second lines as customers move to broadband and wireless solutions. During the quarter the company launched several new service bundles aimed at winning back local telephone customers, which ACS expects to have an impact on traditional access lines in the third quarter and going forward.

• Local network service revenues were consistent year-over-year.

• Excluding the $11.1 million settlement, access revenues were up 5% compared to the previous year.

• Deregulated and other revenues were up $0.8 million from last year as both rents and billing and collection revenues increased.

• Cellular revenues grew by an impressive 7.0% from the prior year period and the Company added almost 1,800 subscribers. ARPU (Average Revenue per Unit) improved by $1.94 to $48.24 and MOU (Minutes of Use) increased by 19.9% from the same period last year.

• Directory business. On May 8th, 2003, ACS announced the completion of the initial public offering of its directories business through a Canadian income trust fund. The offering raised net proceeds of $142.2 million for ACS. The Company’s retained 12.58% interest carried a market valuation of $18.4 million as of June 30, 2003. Prior to the closing of the IPO, Directory contributed $3.4 million in revenues and $1.6 million in EBITDA during the quarter.

• Internet revenues were up significantly on both a sequential and year-over-year basis. This reflects the success of the Company’s DSL rollout and increased revenues from the Company’s State of Alaska contract, including $1.5 million in retroactive revenue recorded during the second quarter. ACS ended the quarter with over 14,800 DSL subscribers, an increase of approximately 900 subscribers on a sequential basis.

• Interexchange revenues were up sequentially from the preceding quarter and EBITDA margins improved. During the quarter, the Company completed the grooming of its database to remove inactive subscribers, leading to a sequential decrease of approximately 13,400 subscribers.

• Operating expenses for the quarter, before depreciation and amortization and the gain on disposal of assets, were flat with the prior year period but grew by $1.9 million on a sequential basis due to the positive increase in sales and higher costs of sales and expenses related to the Company’s State of Alaska contract.

Notes:

EBITDA is presented as an additional means of evaluating the Company’s financial condition, liquidity and its ability to satisfy rating agency and creditor requirements. The Company incurs significant non-cash charges, including depreciation and amortization, related to the capital assets utilized in its operations. EBITDA is a central measure used in the Company’s compliance with debt covenants related to its senior credit facility. EBITDA as defined by the senior credit facility’s credit agreement is net income before interest expense, provisions for taxes, depreciation expense, amortization expense, other noncash charges, and unusual gains. The credit agreement also calls for excluding the EBITDA of any business disposed of during the period. Using this information along with Income from continuing operations provides for a more complete analysis of results of operations. Income from continuing operations is the most directly comparable GAAP measure.

On May 8, 2003, the Company completed the sale of an 87.42% majority interest in its directory business to a Canadian income fund. The Company’s retained interest of 12.58% is expected to generate cash distributions of approximately $1.9 million annually. Pro forma adjustments to EBITDA are presented to reflect the estimated effect of this sale as if it had occurred at the beginning of the periods presented.
