ATSI Record Revenues Result in 181% Increase

526% Improvement in Gross Profit


SAN ANTONIO, TX -- (MARKET WIRE) -- December 14, 2006 -- ATSI Communications, Inc. (OTCBB: ATSX) announced today that revenues for the three months ended October 31, 2006 totaled $6,532,000, a 181% improvement over revenues of $2,682,000 for the three months ended October 31, 2005. The significant gain in revenues resulted in the Company's ninth consecutive quarter of record revenues and an increase of $1.2 million over the immediately preceding quarter. In addition to record revenues for the quarter, the Company produced positive cash flow from operations or net income before non-cash items of $222,000. Non-cash items include long-term incentive compensation for employees and directors that reflects the Company's adoption of SFAS 123R accounting for the amortization expense of stock option grants.

In addition to the Company's continued revenue growth, recent achievements and highlights for the quarter include:

--  526% improvement in gross profit for the three months ended October
    31, 2006 vs. the three months ended October 31, 2005 ($513,000 vs. $82,000
    respectively).
--  Second consecutive quarter of positive cash flow from operations.
--  The Company processed a record volume of 105 million VoIP minutes of
    use ("MOU") during the quarter through its NexTone powered VoIP network.
--  ATSI secures $1.2 million financing with CCA Financial Services, Inc.
    to fund its growth initiatives.
    
Arthur L. Smith, CEO of ATSI, stated, "We are pleased to report that we delivered on our plan to increase gross profit while controlling SG&A expenses. The results are evident with the key improvement in cash flow from operations and an increase in cash reserves during the quarter. Although we do expect our positive revenue growth trend to continue, we remain committed to emphasizing increases in gross profit while maintaining a strict control on expenses." Mr. Smith added, "Increasing our cash reserve and strengthening our balance sheet will assist us with internally financing our growth and allow us to capitalize on strategic opportunities we could not have considered in the past."

Including non-cash items, net loss applicable to common stockholders for the three months ended October 31, 2006 was $186,000 vs. net income applicable to common stockholders of $1,217,000 for the three months ended October 31, 2005 that included a gain of $1,652,00 from discontinued operations. The Company incurred $419,000 in non-cash expense for the quarter ended October 31, 2006 that includes $315,000 in non-cash stock-based compensation. Additional non-cash expenses incurred during the quarter include interest, bad debt, depreciation, amortization, and preferred dividend expense.

Net income before non-cash items is not a term defined by generally accepted accounting principles (GAAP) and may not be comparable to other similarly titled measurements used by other companies. Such non-GAAP measures should be considered in addition to, and not as a substitute for, performance measures calculated in accordance with GAAP. The accompanying table includes a detailed reconciliation of net loss reported in accordance with GAAP to net income before non-cash items.
