Press Release

SALEM, Mass. (March 04, 2009) — Atlantic Tele-Network, Inc. (NASDAQ: ATNI) today reported results for the quarter and year ended December 31, 2008. For the year, revenue was $207.3 million, an increase of $20.6 million, or 11%, as compared to revenue of $186.7 million for the year ended December 31, 2007. Net income was $34.8 million for the year as compared to $37.9 million for the same period in 2007, a decrease of $3.1 million, or 8%. On a per share basis, net income declined by 8% to $2.28 per diluted share from $2.48 per diluted share for the year ended December 31, 2007.

Revenue for the quarter was $55.4 million, an increase of $5.8 million, or 12%, as compared to revenue of $49.6 million for the quarter ended December 31, 2007. Net income was $6.6 million for the quarter as compared to $12.6 million for the same period in 2007, a decrease of $6.0 million, or 48%. On a per share basis, net income declined by 48% to $0.43 per diluted share from $0.82 per diluted share for the quarter ended December 31, 2007.

Revenue and operating income for the quarter was positively impacted by the consolidation of our Bermuda operations following the May 2008 increase in our ownership position, as further discussed below. However, operating income was impacted by losses of approximately $1.0 million from our two previously announced early-stage business acquisitions – IslandCom Telecommunications, a Turks & Caicos-based wireless voice and data company and ION, a New York State fiber optic network, and $1.0 million of costs related to an unsuccessful effort to acquire an entity out of bankruptcy. Operating income for the year and quarter ended December 31, 2007 includes a pre-tax gain of $5.0 million ($6.0 million for the year) related to asset sales at Commnet, including the sale of 59 base stations, and offset by a pre-tax asset impairment charge of $4.4 million at Choice Communications.

"The results for the quarter and the year were mixed" said Michael T. Prior, Chief Executive Officer of Atlantic Tele-Network, Inc. "We are happy with a number of strategic moves we made to position ourselves for continued growth of our businesses. We invested nearly $40 million in acquiring or increasing our stakes in operational businesses, and an estimated additional $40.0 million expanding and upgrading our existing networks. With a robust balance sheet and belief in our strategy and team, we looked hard for new investment opportunities. Before the severe market drop in the last third of the year, we found valuations for later-stage and larger businesses to be too high and instead invested in two, small early-stage businesses – the fiber backhaul business in upstate New York and the wireless business in Turks and Caicos – that fit very well with our existing operations. Although these investments had a negative near-term impact, we expect both to be positive contributors to cash flows in 2010. We also increased our ownership in our Bermuda wireless operation and extended our US wireless footprint with the acquisition of a wireless network in Nevada. We believe both of those transactions strengthen us strategically and provide the potential for increased revenues and cash flows in 2009. Our quest for opportunities also led to a significant increase in legal and related expenses in the fourth quarter with respect to a large transaction we pursued without success. With our net cash position, large recurring cash flows and the larger debt facility we closed just prior to the collapse of the credit markets, we believe we are well positioned to make further strategic investments, although we will continue to take a long-term view and maintain strict investment parameters in terms of value, strategic fit and risk.

"The performance of our existing businesses also contributed to the mixed results for the quarter. Our rural wireless business continued to grow nicely, albeit at the slower pace we expected after the sale of assets at the end of 2007. With 473 base stations at the end of the year (a more than 50% annual increase) and a major new market in Nevada, we see opportunities to continue to grow that business in 2009, although rate reductions and overbuilding will have some negative impact. Our next biggest wireless business, in Bermuda, was flat on a stand-alone basis, but we believe the imminent launch of a UMTS (3G) network will provide some growth for this business in 2009 and 2010, and, as noted above, we expect BDC's expansion to Turks and Caicos also to add growth.

"In Guyana," Mr. Prior added, "the wireless results were disappointing. While the continued loss of subscribers was mainly composed of low-value subscribers, wireless revenues declined significantly in that market. We believe we have the better network and offer better value, but we still need to convince more consumers of that. More importantly in Guyana, 2008 saw a marked increase in international bypass activities. We have taken additional actions to stem that activity, which not only robs GT&T of revenue and profit but also significantly reduces the government's VAT and income tax collections. Although governmental authorities have made some effort to assist us, we have yet to see a major reduction in bypass activity. Lastly, in New England the core business held up well and continued to grow in a tough environment. We believe that the addition of ION and some new services to customers will provide a boost to results from this market in future periods."

Fourth Quarter 2008 Operating Highlights

The following operating results for the quarter ended December 31, 2008 are compared against the same period in 2007 unless otherwise indicated.

Wireless Revenue. Wireless revenue increased by $7.2 million, or 32%, to $30.0 million from $22.8 million. The consolidation of our Bermuda Digital Communications (BDC) operations, which began as of May 15, 2008, contributed $6.1 million of the increase. Notwithstanding the sale of 59 base stations at the end of 2007, our U.S. rural wireless business increased revenues by $1.9 million as a result of its ongoing deployment of new base stations along with growth in recurring voice and data traffic. We ended the quarter with a total of 473 base stations in our U.S. network, – the 2008 total includes 46 sites from the acquisition of wireless network assets of CC Communications in Nevada in late December – up from 303 base stations as of December 31, 2007. This acquisition had a negligible impact on results for the quarter. In Guyana, our wireless revenue declined by $0.7 million, as increased competition led to a decrease in our wireless customer base to approximately 248,000 subscribers as of December 31, 2008 from 328,000 as of December 31, 2007 and 273,000 as of September 30, 2008.

Local Telephone and Data Revenue. Local telephone and data revenue grew to $13.3 million compared to $12.5 million in 2007, an increase of 6%. Sovernet's local telephone and data revenue increased $0.9 million, or 24%, to $4.6 million from $3.7 million in 2007. This increase is mainly due to Sovernet's acquisition of ION. Our Guyana subsidiary saw a slight increase in its local telephone and data revenue as access lines increased from 132,000 lines to 139,000 lines, or 5%, however, these increases were offset by a decrease in data revenue at our Virgin Islands subsidiary.

International Long Distance Revenue. International long distance revenue, all of which is generated by our GT&T subsidiary, was $11.1 million in 2008, a decrease of $2.2 million, or 17%, from $13.3 million in 2007. We believe this decrease primarily is a result of a considerable increase in illegal bypass activities in the quarter resulting in lost revenue opportunities, and an overall reduction in call volume into Guyana as an outcome of the current worldwide economic slowdown.

Operating Expenses. Excluding the net impact from the previously mentioned impairment of assets and gain on the sale of assets in 2007, operating expenses increased by $10.0 million, or 33%, from $29.9 million to $39.9 million for the fourth quarter 2007 and 2008, respectively. Of this increase, $5.7 million represents operating expenses of BDC which the Company began consolidating as of May 2008, $1.5 million in operating expenses at ION, which was acquired in August 2008, and $1.0 million for unsuccessful acquisition efforts that were previously mentioned. In addition, depreciation and amortization expense at Commnet increased $1.0 million as a result of our network expansion in the rural U.S. Operating expenses for the fourth quarter 2007 and 2008 included non-cash stock based compensation expense of $0.4 million and $0.2 million, respectively.

Operating Income. Operating income declined by $4.8 million, or 24%, from $20.3 million to $15.5 million for the quarter. This was due in part to the decrease in Guyana's international long distance revenue, as well as the addition of the early stages businesses of ION and IslandCom.
