·Adjusted EBITDA was up 17% to $41.0 million

·Operating income reached $28.2 million, up 41%

Beverly, MA (October 29, 2014) — Atlantic Tele-Network, Inc. (NASDAQ: ATNI), today reported results for the third quarter and nine months ended September 30, 2014. Unless otherwise indicated, the discussion of the Company’s results is focused on its continuing operations, and comparisons are to the same period in the prior year. Results for all periods presented reflect classification of the Company’s U.S. retail wireless business operated under the “Alltel” name as discontinued operations as a result of the completion of the Company’s sale of this business to AT&T Mobility LLC on September 20, 2013.

Third Quarter 2014 Financial Results

“Our strong revenue and earnings growth in the first half of the year continued in the third quarter, led by our domestic wireless business, said Michael Prior, Chief Executive Officer. “Domestic data traffic increased significantly across our U.S. wholesale network, more than offsetting the expected decline in pricing that we have cited in earlier quarters of this year.   This volume growth primarily results from our capital investments to upgrade network capacity and coverage and we see additional opportunities to invest in 2015.  In the last eighteen months alone, we have increased the number of 3G or higher base stations from under 5% of our network to over 65% today.

We are pleased with the share gains we have achieved year-to-date in most of the markets within our international wireless portfolio and believe there are improvements we can make to enhance our competitive positioning and additional efficiencies we can achieve to optimize these assets. Wireline results for the first nine months of this year were slightly ahead of the comparable period last year, as revenues from U.S. wholesale transport activities and international broadband more than offset the decline in voice and other legacy revenues in our wireline markets.

“Cash from operations reached $55.7 million in the first nine months, and we remain committed to a steady, long-term approach to capital expenditures and investments in our existing portfolio,” Mr. Prior noted.

Third quarter revenues were $89.4 million, 13% above the $79.4 million reported for the third quarter of 2013.  Adjusted EBITDA(1) for the 2014 third quarter was $41.0 million, a 17% increase over the $35.0 million reported for the 2013 third quarter. Operating income was $28.2 million, up 41% compared to last year’s $20.0 million.  Net income from continuing operations attributable to ATN’s stockholders was $16.2 million or $1.01 per diluted share, compared to $1.6 million, or $0.10 per diluted share, for the third quarter of 2013.  Net income for 2013 was inclusive of $2.7 million in transaction-related charges, as well as $10.4 million of interest rate swap contract termination charges and the write off of deferred financing costs, which were both related to the pre-payment of the Company’s long term debt under its credit facility.

On September 19, 2014, ATN’s Board of Directors increased the Company’s cash dividend for the sixteenth consecutive year. The quarterly dividend was increased 7% to $0.29 per share.

Nine Month 2014 Financial Results

Nine month revenues were $247.8 million, 15% above the $215.8 million reported for the same period in 2013.  Adjusted EBITDA was $104.1 million, up 21% from $86.1 million in the prior year period; operating income increased 37% to $66.0 million; and net income from continuing operations attributable to ATN’s stockholders was $35.5 million, or $2.22 per diluted share, as compared with the same period in 2013 of $12.8 million, or $0.81 per diluted share, inclusive of the special charges noted above.

For the first nine months of 2013, net income attributable to ATN’s stockholders from discontinued operations was $4.6 million, or $0.29 per diluted share, and the net gain attributable to ATN’s stockholders on the disposal of the Alltel business was $276.5 million, or $17.51 per share.

Third Quarter 2014 Operating Highlights

U.S. Wireless

U.S. wireless revenues primarily consist of voice and data revenues from the Company’s wholesale roaming operations.  Total revenues from the U.S. wireless business were $44.3 million in the third quarter of 2014, an increase of 35% from the $32.8 million reported in the third quarter of 2013.  This strong revenue performance was driven by increased data traffic across the Company’s expanded domestic wireless network.  We expect to see significantly lower average wholesale data pricing in 2015 which should be offset in part, as we continue to expand our network capabilities, reach and capacity.  Data revenues accounted for 68% of U.S. wireless revenues in the 2014 third quarter compared to 56% in the similar year-ago period.   The Company ended the third quarter with 716 wholesale-only base stations in service compared to 579 at the end of last year’s third quarter.

International Wireless

International wireless revenues include retail and wholesale voice and data wireless revenues from international operations in Bermuda and the Caribbean. International wireless revenues were $21.6 million, a decrease of 6% over the $22.9 million reported in the third quarter of 2013, as a result of market share losses in Guyana and lower wholesale roaming revenues in many of our Island properties resulting from anticipated rate declines.  We continue to expect retail revenues to continue to grow but wholesale revenues to decline in our international markets over time.

Wireline

Wireline revenues are generated by the Company’s wireline operations in Guyana, including international telephone calls into and out of that country, by its integrated voice and data and wholesale transport operations in New England and New York State, and by its U.S. based wholesale long-distance voice services. Wireline revenues of $21.5 million, were flat compared with the third quarter of 2013 resulting from domestic unit price declines in enterprise offerings and decreases in voice traffic in all wireline markets, offset by an increase in broadband subscribers in Guyana and in U.S. wholesale transport revenue.
