RCN Reports Second Quarter 2010 Results

Revenue Reaches $195 Million

EBITDA Reaches $53 Million, Including Deal Costs of $3 Million

Free Cash Flow Reaches $10 Million

HERNDON, Va., August 10, 2010 — RCN Corporation (NASDAQ: RCNI) today announced second quarter 2010 results.

RCN Corporation is a leading provider of all-digital and high-definition video, high-speed internet, and premium voice services to residential and small-medium business customers, in Philadelphia, Lehigh Valley (PA), New York, Boston, Chicago and Washington D.C., as well as high-capacity transport services to carrier and large enterprise customers.

“During the second quarter, RCN generated solid, consistent levels of Revenue, EBITDA and Free Cash Flow,” stated Peter D. Aquino, President and Chief Executive Officer. “We continued to make progress in our key customer-facing initiatives, rolling out TiVoÒ Premiere from RCN HD DVR and DOCSIS 3.0, and RCN Metro successfully launched its Xtreme Network in New York and New Jersey. We remain focused on continued execution while we finalize the process of closing our merger with an affiliate of ABRY Partners.”

Second Quarter Review
Following are highlights of second quarter 2010 results for consolidated RCN and for the company’s two reporting segments: Residential/Small-Medium Business, comprised of the RCN and RCN Business Services business units; and RCN Metro Optical Networks.

Consolidated Results

•		Revenue. Total revenue of $195 million increased 1% from $192 million in the second quarter of 2009 and increased 2% from the first quarter of 2010.

•		EBITDA. EBITDA of $53 million decreased from $56 million in the second quarter of 2009 and increased slightly from the first quarter of 2010. Included in 2010 EBITDA results are costs related to the pending acquisition of the company, including $1.3 million in the first quarter of 2010 and $3.0 million in the second quarter of 2010. Excluding these costs, EBITDA increased 2% from the second quarter of 2009 and 4% from the first quarter of 2010, and EBITDA margin of 29% grew slightly from the second quarter of 2009 and the first quarter of 2010. EBITDA is a non-GAAP financial measure — see “Non-GAAP Measures” below.

•		Capital Expenditures. Capital expenditures were $30 million, up from $25 million in the second quarter of 2009 and $22 million in the first quarter of 2010, driven primarily by the timing of certain investments in the Residential/Small-Medium Business segment.

•		Free Cash Flow. Free cash flow was $10 million, compared to $10 million in the second quarter of 2009 and $7 million in the first quarter of 2010. Free cash flow also included costs related to the pending acquisition of the company, as noted above. Free cash flow is a non-GAAP financial measure — see “Non-GAAP Measures” below.

Residential/Small-Medium Business Segment

•		Revenue. Residential/Small-Medium Business revenue of $145 million was comparable to $145 million in the second quarter of 2009 and increased 3% compared to the first quarter of 2010. Year-over-year revenue comparisons reflect 8,000 fewer customers partially offset by an increase in average revenue per customer (“ARPC”) to $113.

•		EBITDA. Residential/Small-Medium Business EBITDA of $37 million decreased from $40 million in the second quarter of 2009 and increased from $36 million in the first quarter of 2010. Included in 2010 EBITDA results are costs related to the pending acquisition of the company, including $0.9 million in the first quarter of 2010 and $2.2 million in the second quarter of 2010. Excluding these costs, EBITDA of $40 million decreased 1% from the second quarter of 2009 and increased 6% from the first quarter of 2010, and EBITDA margin of 27% decreased slightly from the second quarter of 2009 and increased nearly 100 basis points from the first quarter of 2010.

•		Capital Expenditures. Residential/Small-Medium Business capital expenditures were $21 million, up from $16 million in the second quarter of 2009 and $12 million in the first quarter of 2010, due primarily to the timing of key investments, including DOCSIS 3.0, the launch of TiVoÒ Premiere from RCN HD DVR, and selected footprint expansion.

•		Customers and RGUs. Residential/Small-Medium Business customers of approximately 422,000 decreased 8,000 compared to the second quarter of 2009 and 4,000 compared to the first quarter of 2010, due in part to continued tightening of credit standards for new customers in certain markets. Total revenue generating units of approximately 886,000 decreased by 25,000 compared to the second quarter of 2009 and decreased by 10,000 compared to the first quarter of 2010, as continued growth in data RGUs was offset by a reduction in voice RGUs, consistent with trends for highly-penetrated landline voice providers, and a decrease in video RGUs, due to the customer trends noted above.

RCN Metro Optical Networks Segment

•		Revenue. RCN Metro revenue of $50 million increased 5% from $47 million in the second quarter of 2009, and increased 1% from the first quarter of 2010, driven primarily by continued growth in transport services as well as growth in IP and colocation services.

•		EBITDA. RCN Metro EBITDA of $16 million increased slightly from the second quarter of 2009 and decreased slightly from the first quarter of 2010. Included in 2010 EBITDA results are costs related to the pending acquisition of the company, including $0.3 million in the first quarter of 2010 and $0.8 million in the second quarter of 2010. Excluding these costs, EBITDA increased 7% from the second quarter of 2009 and decreased slightly from the first quarter of 2010, with EBITDA margin of 34% growing nearly 100 basis points from the second quarter of 2009 and declining by nearly 100 basis points from the first quarter of 2010.

•		Capital Expenditures. RCN Metro capital expenditures were $9 million, flat from $9 million in the second quarter of 2009 and down from $10 million in the first quarter of 2010.

Reported Results
Revenue was $195 million in the second quarter of 2010, compared to $192 million in the second quarter of 2009 and $190 million in the first quarter of 2010. Net income was $3 million in the second quarter of 2010, compared to a net loss of $9 million in the second quarter of 2009 and net income of $5 million in the first quarter of 2010. As reported previously, the swing to net income from net loss is due primarily to lower depreciation expense, as certain assets became fully depreciated during 2009.

Michael T. Sicoli, Chief Financial Officer, stated, “In the second quarter, RCN generated strong levels of free cash flow despite the inclusion of deal-related costs and increased investments in capital expenditures. We are pleased with the results to date of our decision to tighten up-front customer credit standards in certain markets within our Residential/Small-Medium Business segment, and we will expand the program to additional markets during the third quarter to support our long-term profitability.”

Non-GAAP Measures
In addition to the results presented in accordance with Generally Accepted Accounting Principles (“GAAP”) throughout this press release, RCN has presented non-GAAP financial measures, such as EBITDA, EBITDA Margin, Free Cash Flow and ARPC. RCN believes that these non-GAAP measures, viewed in addition to and not in lieu of its reported GAAP results, provide useful information to investors because they are an integral part of RCN’s internal evaluation of operating performance. In addition, they are measures that RCN uses to evaluate management’s effectiveness. Reconciliations to comparable GAAP measures as well as definitions begin on page 8. RCN’s non-GAAP financial measures may not be comparable to similarly titled measures presented by other companies.

EBITDA is defined as net income (loss) plus income tax benefit (expense), other (expense) income net, (loss) gain on sale of assets, interest expense, investment income, depreciation and amortization, non-cash stock-based compensation expense and other special items including impairments, exit costs and other charges. EBITDA margin represents EBITDA divided by total revenues. We believe that EBITDA provides useful information to investors because it is an indicator of the strength and performance of our ongoing business operations, including our ability to fund discretionary spending such as capital expenditures and other investments and our ability to incur and service debt. While depreciation and amortization are considered operating costs under generally accepted accounting principles, these expenses represent non-cash current period allocation of costs associated with long-lived assets acquired or constructed in prior periods. EBITDA is a calculation commonly used as a basis for investors, analysts and credit rating agencies to evaluate and compare the periodic and future operating performance and value of companies within the cable industry. EBITDA, as defined above, may not be similar to EBITDA measures of other companies, is not a measurement under accounting principles generally accepted in the United States and should be considered in addition to, but not as a substitute for, the information contained in our statements of operations.

Segment EBITDA is defined as operating income before depreciation and amortization, non-cash stock-based compensation expense, exit costs and restructuring charges. This measure eliminates the significant level of non-cash depreciation and amortization expense that results from the capital-intensive nature of our businesses and from intangible assets recognized in business combinations, as well as non-cash stock-based compensation and other special items such as exit costs and other restructuring charges. We use this measure to evaluate our consolidated operating performance and the performance of our operating segments, and to allocate resources and capital. It is also a significant performance measure in our annual incentive compensation programs. We believe that this measure is useful to investors because it is one of the bases for comparing our operating performance with that of other companies in our industries, although our measure may not be directly comparable to similar measures used by other companies. Because we use this metric to measure our segment profit or loss, we reconcile it to operating income, the most directly comparable financial measure calculated and presented in accordance with GAAP. Segment EBITDA should not be considered as a substitute for operating income (loss), net income (loss), net cash provided by operating activities, or other measures of performance or liquidity we have reported in accordance with GAAP.

Average monthly revenue per customer, or ARPC, is an industry metric that measures revenues, excluding commercial and other residential revenue (consisting of dial-up and reciprocal compensation) per period divided by the average number of customers during that period. We believe that ARPC provides useful information concerning the appeal of our service offerings and our rate plans. ARPC, as defined above, may not be similar to ARPC measures of other companies, is not a measurement under accounting principles generally accepted in the United States and should be considered in addition to, but not as a substitute for, the information contained in our statements of operations.

Free cash flow is defined as net cash from operating activities, plus net cash from investing activities, activity in short-term investments and restricted investments. We believe that free cash flow provides useful information to investors, analysts and our management about the cash generated by our core operations after interest and our ability to fund scheduled debt maturities and other financing activities. Free cash flow, as defined above, may not be comparable to free cash flow measures of other companies, is not a measurement under accounting principles generally accepted in the United States and should be considered in addition to, but not as a substitute for, the information contained in our statements of cash flows.
