Business Editors

ST. THOMAS, U.S. Virgin Islands--(BUSINESS WIRE)--April 30, 2003

Atlantic Tele-Network, Inc. (AMEX:ANK), today reported earnings of $2.8 million, or $0.56 per share for the quarter ended March 31, 2003. For the quarter ended March 31, 2002, the Company earned $2.0 million, or $0.40 per share. First quarter earnings for 2003 represent a 40% increase over last year's first quarter.

Telephone operating revenues were $18.1 million as compared to $15.3 million for the first quarter of 2002, an increase of $2.8 million, or 18%. The increase in telephone operating revenue is principally attributable to a 31% increase in local exchange revenue and an 8% increase in international long distance revenue, or $1.9 million and $0.7 million respectively. The increase in local exchange revenue reflects substantial additions of both wireline and cellular subscribers from the prior period. The increase in international long distance revenue was due to an increased volume of traffic following the mandated reduction in international settlement rates for traffic between Guyana and the United States effective January 1, 2002. Cellular subscribers increased from 51,244 on March 31, 2002 to 92,756 on March 31, 2003, an increase of 81%, while wireline subscribers increased from 81,386 to 87,057, reflecting total additions of 5,671, or 7% from the prior period.

Total telephone operating expenses were $11.0 million for the first quarter of 2003 compared with $10.2 million for the corresponding quarter of 2002, an increase of 8% or $0.8 million. A reduction of international long distance expense due to the full implementation of the FCC mandated reduction in international settlement rates was offset by higher depreciation, power, legal and other expenses related to the expansion of facilities.

Cornelius B. Prior, Jr., Chairman of the Board and Chief Executive Officer of Atlantic Tele-Network, Inc. said, "We were pleased to read in the Guyana press on March 21, 2003 of President Jagdeo's direction to the Prime Minister, Sam Hines, to reconvene the Government's negotiating team with respect to talks with ATN and GT&T representatives begun in Trinidad last April concerning new telecommunications policy initiatives of the Government of Guyana. In view of this positive development, we have decided not to appeal the recent decision of the U.S. District Court in Washington, D.C. which held, among other things, that ATN had no private right of action to challenge a proposed loan to Guyana by the IADB which we believed would have infringed our contractual rights."

"Our Guyana subsidiary, GT&T, continues to grow strongly, reflecting additional investment last year of $14.5 million and enabling us to expand both our cellular operations and our fixed wireline customers substantially. Teledensity in Guyana (phone lines per total population) is now over 20%, compared to less than 2% when we began operation there in 1991. Cellular operations in Bermuda also prospered, with our share of BDC's net income up 55% from the first quarter of 2002, up 200% or three times the first quarter of 2001, and now contributing almost 20% of ATN's net income."

Its principal subsidiary, Guyana Telephone and Telegraph Company, Limited, is 80% owned by ATN and is the national telephone service provider in the Cooperative Republic of Guyana for all local, long-distance and international service.
