Financial Highlights: Second Quarter 2011 Compared to Second Quarter 2010

• Revenues of $84.9 million increased by $0.4 million, or 0.5 percent, from $84.5 million in the prior year:
  • Wireless revenue increased by $1.7 million, or 4.9 percent. Declines in service revenue of $1.1 million and equipment revenue of $0.5 million were offset by $3.3 million in higher wholesale, roaming and other revenue.
  • Enterprise revenue increased by $0.8 million, or 6.9 percent, with higher data revenue driving growth.
  • Retail, wholesale and access wireline revenues declined by $2.1 million, or 5.6 percent, with growth in Internet products partially offsetting continued revenue declines caused by erosion in the traditional wireline business.
• EBITDA of $30.7 million decreased by $0.8 million, or 2.7 percent, from $31.5 million in the prior year.
  • Wireless EBITDA was $16.2 million in the second quarter. Equipment subsidies impacted EBITDA by $1.7 million compared to the prior year.
  • Wireline EBITDA declined by $0.8 million, or 5.3 percent, to $14.5 million. Lower access revenue of $1.4 million was significantly offset by a non-recurring favorable settlement of a previous contact dispute.

• Net loss of $3.7 million, or $0.08 per share, compared to net loss of $27.7 million, or $0.62 per share in the prior year. Prior year losses were impacted by a non-cash charge to income tax expense of $29.7 million.

With the closing of our convertible note offering in the quarter, we extended the maturity for over 95 percent of our outstanding long-term debt until 2016. Cash balances now exceed $20 million, giving us headroom to fund the recently announced 4G LTE wireless network initiatives,” said Wayne Graham, ACS chief financial officer.

Forward-Looking EBITDA Guidance

This press release includes information related to management's estimate of EBITDA for the year ending December 31, 2011. EBITDA, as defined by the company, may not be similar to EBITDA measures used by other companies and is not a measurement under generally accepted accounting principles (GAAP). Management believes that EBITDA provides useful information to investors about the company's performance because it eliminates the effects of period-to-period changes in costs associated with capital investments, interest and stock-based compensation expense that are not directly attributable to the underlying performance of the company's business operations. Management believes the most directly comparable GAAP measure would be "Net cash provided by operating activities." Due to the difficulty in forecasting and quantifying the amounts that would be required to be included in this comparable GAAP measure, the company is not providing an estimate of year-end 2011 net cash provided by operating activities at this time.

Forward-Looking Statements

This press release includes certain "forward-looking statements," as that term is defined in the Private Securities Litigation Reform Act of 1995.
