Management Comments

“I am very pleased to report on the important progress achieved by Alteva in 2012 and year-to-date in 2013.  I fully appreciate the trust that our Board of Directors has placed in me by naming me Alteva’s Chief Executive Officer.  I am confident that together we will continue our pursuit of profitable growth and increased value for our shareholders in 2013 and beyond,” said David Cuthbert.

“We have made significant investments in the Company’s future and a platform for growth has been built.  Benefiting from the established presence of the Alteva brand in the communications industry and embracing a singular vision for generating profitable growth throughout the organization, the entire Company began conducting business as Alteva in January 2013.  Additionally, we have reorganized our corporate structure, significantly bolstered and reformulated our management team, and invested in creating a business infrastructure with flexible processes and systems.

“During the course of 2012, our UC revenues increased to approximately half of our consolidated revenues for the first time in Alteva’s history.  Furthermore, we achieved the highest level of quarterly UC contract volume in the Company’s history.  This is an exciting and promising inflection point but we have only begun to tap into the large and growing market for cloud-based UC services and applications.  We are now razor focused on setting our sights on growing our top line such that we may leverage our infrastructure to return the Company back to profitability on an operating basis.  Only then may we begin to say that our transition has achieved meaningful success.  The unified Alteva team is ready for this challenge and we are energized by the opportunities that lie ahead in 2013.  With our plans for aggressive top line growth, leveraging the investments made in the Company during 2012 and ongoing management of expenses, we have set a goal of achieving positive EBITDA, exclusive of O-P contributions, by the end of first quarter 2014.”

Fourth Quarter 2012 Results

Revenues for the three-month period ended December 31, 2012 were $6.9 million, as compared to $7.1 million for the same period in 2011.

In the first quarter of 2012, the Company realigned its segment reporting and management structure as a result of the Alteva acquisition in 2011.  The Company’s segments are strategic business units that offer different products and services and are now managed as Unified Communications (“UC”), and Telephone. Revenues discussed in this press release for periods prior to the first quarter of 2012 have been presented on the basis of the new segment reporting.

Revenues from UC services, net of eliminations, were $3.4 million in the fourth quarter of 2012, an increase of 10.7% from $3.1 million in the prior year period.  As a percentage of consolidated revenue, the UC segment contributed nearly 50% of revenues in the fourth quarter of 2012 as compared with 43% in the same period of the prior year.  The increase in UC revenues was primarily attributable to organically generated UC services revenue growth.

Telephone services revenues, net of eliminations, were $3.5 million in the fourth quarter of 2012, a decrease from $4.0 million in the corresponding 2011 period.  The Telephone segment contributed approximately 50% of revenues in the fourth quarter 2012 as compared with 57% in the fourth quarter of 2011. The decrease was primarily due to lower Universal Service Fund revenues.  Lower Telephone services revenues also resulted from losses due to wireless substitution and competition for other triple play service providers, partially offset by an increase in access lines rates.

Gross profit increased by 21.6% to $3.2 million in the fourth quarter of 2012 from $2.6 million in the same period of 2011.  Gross profit as a percentage of revenues increased to 46.2% in the fourth quarter 2012 from 37.0% in the 2011

period.  The improvement in gross profit in dollars as well as on a margin basis primarily reflects (i) the substantial increase in revenues contributed by the UC segment in the fourth quarter of 2012 compared to the same period last year, (ii) and the Company’s ability to leverage its infrastructure.

Selling, general and administrative (“SG&A”) expenses in the fourth quarter of 2012 increased to $6.5 million from $5.1 million in the corresponding period of 2011.  The 27% increase in SG&A expenses reflects the additional operating expenses for Alteva as well as the current and ongoing requirements to support the Company’s cloud communications growth strategies.

Operating expenses in the fourth quarter of 2012 included an $8.9 million non-cash write down of fixed assets in the Telephone segment due to the continued decline in this segment’s operating performance.

Total other income for the three-month period ended December 31, 2012 was $3.2 million as compared to $1.0 million for the same period in 2011.  This increase is primarily due to the accounting treatment of O-P distributions of $3.25 million in the fourth quarter of 2012 as compared with $1.2 million in the prior year period which was recorded based on the amount in excess of the Company’s share of the O-P earnings for that period as opposed to being applied to the investment account.

For the three-month period ended December 31, 2012, the Company had a net loss of $(7.1) million, or $(1.24) per basic and diluted common share, as compared to a net loss of $(1.9) million, or $(0.34) per basic and diluted common share, for the three-month period ended December 31, 2011.  Excluding the non-cash fixed asset write down in the Telephone segment, the fourth quarter 2012 net loss would have been $(1.2) million, or $(0.21) per basic and diluted common share, as compared to a net loss of $(1.9) million, or $(0.34) per basic and diluted common share, in the same period of the prior year.

Restatement of Financial Statements

On March 12, 2013, the Company’s Audit Committee of its Board of Directors, in consultation with management, determined that our consolidated balance sheets for the first three quarters of 2012 and for 2009, 2010 and 2011 should be restated due to an error in the calculation of the deferred income taxes related to the temporary difference of accumulated depreciation of fixed assets. The total adjustment relating to the correction of the deferred income taxes was an increase in non-current deferred tax liability and a reduction in retained earnings of $1.3 million, and did not impact statement of operations or cash flows for any of those periods.  The restated financial statements are included in the Company’s 2012 Annual Report on Form 10-K.
