Press Release

Salem, MA (November 5, 2008) — Atlantic Tele-Network, Inc. (NASDAQ: ATNI) today reported results for the quarter ended September 30, 2008. For the three months ended September 30, 2008, was $55.9 million, an increase of $7.8 million, or 16%, as compared to revenue of $48.1 million for the three months ended September 30, 2007. Operating income increased 17% for the quarter to $20.4 million, as compared to $17.4 million for the quarter ended September 30, 2007. Net income was $10.1 million for the quarter, as compared to $9.4 million for the same period in 2007, an increase of $0.7 million, or 7%.

On a per share basis, net income increased by 8% to $0.66 per diluted share from $0.61 per diluted share for the three months ended September 30, 2007. Earnings per share were negatively impacted this quarter by $0.04 as a result of the addition of two early-stage businesses; which include IslandCom Telecommunications, a Turks & Caicos-based wireless company, a controlling interest of which was acquired by Bermuda Digital Communications (BDC) in September, and ION, a New York State fiber optic network, in which Sovernet acquired a majority stake of in August.

For the nine months ended September 30, 2008, revenue was $152.0 million, an increase of $14.8 million or 11% as compared to revenue of $137.2 million for the nine months ended September 30, 2007. Operating income increased 15% for the nine months September 30, 2008 to $54.1 million, as compared to $46.9 million for the same period in 2007. Net income was $28.2 million for the nine months ended September 30, 2008, as compared to $25.3 million for the same period in 2007, an increase of $2.9 million or 11%. On a per share basis, net income also increased by 11% to $1.85 per diluted share from $1.66 per diluted share for the nine months ended September 30, 2007.

“Our wireless operations accounted for well over half of all revenue in the quarter” said Michael T. Prior, Chief Executive Officer of Atlantic Tele-Network, Inc. “Strong growth in our US wireless operations continued, and this business unit accounted for two-thirds of total wireless revenue. This growth largely reflects the success of our accelerated build-out program in rural areas of the West and Midwest in the first half of 2008 to meet the needs of our larger carrier customers. The consolidation of our Bermuda operations, following our ownership increase earlier this year, was also a large component of the year-on-year increase in wireless revenue. In Bermuda, subscriber levels were flat overall, although losses in the smaller pre-paid segment were offset in large part by gains in ARPU from higher-value users with data contracts. We expect the recent investment in Turks and Caicos by Bermuda to provide a small boost to wireless revenue over the next twelve months; however, the start-up nature of those operations is likely to generate modest losses for at least that period.

“On the fixed line side of our business, our Guyana subsidiary helped drive another nice quarter of growth, but we expect to reduce our build-out of local access lines in coming quarters. We are excited by Sovernet’s expansion beyond Vermont and New Hampshire with its investment, alongside a number of rural telephone operators, in a state-wide fiber optic network in New York State. While we were happy to make these two new investments in the third quarter, they are relatively small and, given the strength of our balance sheet, we continue to look for larger opportunities.”

Third Quarter 2008 Operating Highlights
The following operating results for the quarter ended September 30, 2008 are compared against the same period in 2007 unless otherwise indicated.

Wireless Revenue. Wireless revenue increased by $8.3 million, or 38%, to $30.4 million from $22.1 million. Of this increase, $5.1 million was attributable to the consolidation of BDC, our Bermuda wireless operation, which the Company began consolidating as of May 15, 2008. In addition, our U.S. rural wireless business saw revenue increase by $3.9 million, or 24%, to $19.9 million from $16.0 million, notwithstanding the sale of 59 sites in the fourth quarter of 2007. These increases were offset by a $0.7 million decrease in our wireless business in Guyana. Our U.S. rural wireless business continued to deploy new base stations and ended the quarter with a total of 396 base stations, compared to 286 on September 30, 2007. In Guyana, our wireless revenue decline reflects the continued impact of competition that entered the market in late 2006 and a decline in subscribers from 330,000 as of September 30, 2007 to 273,000 as of September 30, 2008.

Local Telephone and Data Revenue. Local telephone and data revenue grew to $12.8 million compared to $11.6 million in 2007, an increase of $1.2 million, or 10%. Our Guyana operations increased their local telephone and data revenue by $0.7 million, or 10%, from $6.8 million to $7.5 million, as access lines increased from 127,000 lines to 136,000 lines, or 7%, and interconnect fees increased. In New England, Sovernet recorded $4.1 million in local telephone and data revenue, an increase of $0.4 million over 2007 due largely to the acquisition of ION, an early stage fiber based transport provider, in August 2008.

International Long Distance Revenue. International long distance revenue, all of which is generated by our GT&T subsidiary, was $11.8 million in 2008, a decrease of $1.5 million, or 11%, from $13.3 million in 2007. This decrease, we believe, primarily was a result of a considerable increase in illegal bypass activities in the quarter, resulting in lost revenue opportunities.

Operating Expenses. Operating expenses increased by $4.9 million, or 16%, from $30.7 million to $35.6 million for the third quarter of 2007 and 2008, respectively. Of this increase, $3.9 million represents operating expenses of BDC which the Company began consolidating as of May 15, 2008. In addition, the Company recorded increased depreciation and amortization expense associated with our network expansion in the rural U.S and in Guyana. Such increases, however, were partially offset by a significant decrease in marketing expenses in Guyana, down from historical highs in 2007. Operating expenses for the third quarter 2007 and 2008 also included non-cash stock based compensation expense of $0.2 million in each quarter.

Operating Income. Operating income increased by $3.0 million, or 17%, from $17.4 million to $20.4 million for the quarter. This increase came predominately from the consolidation of the results of the operations of BDC, effective May 15, 2008 and U.S. rural wireless revenue growth.
