Maxcom Telecomunicaciones Third Quarter 2007 Unaudited Results

MEXICO CITY, Oct. 31 /PRNewswire-FirstCall/ -- Maxcom Telecomunicaciones S.A.B. de C.V. (NYSE: MXT) (BMV: MAXCOM) (BMV: CPO) today announced its Third Quarter 2007 unaudited results.

LINES:

The number of voice lines in service at the end of 3Q07 increased 26% to 321,003 lines, from 255,174 lines at the end of 3Q06, and 7% when compared to 299,744 lines in service at the end of 2Q07.

During 3Q07, 29,306 new voice lines were installed, 3% above the 28,551 lines installed during 3Q06. When compared to 2Q07, the number of installations decreased 3% from 30,343 lines.

During the quarter, the monthly churn rate for voice lines was 1.7%, above the 1.6% monthly average churn experienced during 3Q06 and 2Q07.

Data equivalent lines (at 64Kbps) increased 226% to 125,960 at the end of 3Q07 from 38,640 at the end of 3Q06, and 105% when compared to 61,586 equivalent lines at the end of 2Q07. The increase was mainly driven by installations to residential customers.

During the third quarter, we launched our paid TV service in the city of Puebla. As of September 30, 2007, we had already installed 3,340 TV sets for 2,755 subscribers.

CUSTOMERS:

The number of total customers (voice, data and TV) grew 23% to 228,605 at the end of 3Q07, from 185,979 at the end of 3Q06, and 10% when compared to 207,309 customers at the end of 2Q07.

REVENUES:

Revenues during 3Q07 increased 28% to Ps$607.6 million, from Ps$476.2 million reported in 3Q06. Voice revenues in the quarter increased 33% to Ps$478.2 million, from Ps$359.0 million during 3Q06, and were primarily driven by a 26% increase in voice lines and a higher average revenue per line (ARPU). The ARPU increase was mainly attributed to an increase in public telephony services. Data revenues in 3Q07 were Ps$31.4 million, a 66% increase when compared to Ps$18.9 million in 3Q06, driven by the increase in data equivalent lines. Wholesale revenues in 3Q07 were even at Ps$98.0 million, when compared to Ps$98.2 million recorded in 3Q06.

3Q07 revenues represented a 7% increase from the Ps$569.9 million reported in 2Q07. Voice revenues in 3Q07 increased 8% from Ps$442.6 million in 2Q07, while data revenues increased to Ps$31.4 million, and were 23% higher than those reported in 2Q07 at Ps$25.5 million. During 3Q07, revenues from Wholesale customers decreased 4% from Ps$101.7 million recorded in 2Q07.

COST OF NETWORK OPERATIONS:

Cost of Network Operations in 3Q07 was Ps$249.7 million, 27% above the cost of Ps$196.0 million in 3Q06. With outbound traffic decreasing 15%, the cost per minute increased as a result of higher operating costs in our public phones due to a larger number of public phones in service, along with higher long distance termination charges and higher minutes to cellular phones.

The Ps$53.7 million increase in the Cost of Network Operations was generated by: (i) Ps$48.8 million, or 30% increase in network operating services, as a result of Ps$22.3 million higher operating costs related to public telephones, Ps$15.7 million higher calling party pays interconnection fees, Ps$5.4 million higher leases of circuits and ports, Ps$4.3 million higher long distance interconnection fees, Ps$1.4 million higher cost for paid TV operations, and Ps$0.2 higher Internet services costs, partially offset by Ps$0.5 million decrease in other services costs, such as CATV and cellular operations; (ii) Ps$4.2 million, or 14% increase in technical expenses; and, (iii) Ps$0.7 million, or 16%, increase in installation expenses and cost of disconnected lines.

Cost of Network Operations increased 3% on a quarter-over-quarter basis when compared to Ps$242.2 million in 2Q07. The Ps$7.5 million increase in Cost of Network Operations was generated by: (i) Ps$6.5 million, or 3% increase in Network operating services, as a result of Ps$2.9 million higher leases of circuits and ports, Ps$2.0 million higher cost of operation of public telephones, Ps$1.5 million higher calling party pays interconnection fees, Ps$1.4 million higher cost for paid TV operations, and Ps$0.8 million higher Internet services costs; partially offset by Ps$1.1 million lower long distance interconnection fees, and Ps$1.0 million lower other services cost, such as CATV and cellular operations; (ii) Ps$1.3 million, or 4%, increase in technical expenses; and, (iii) Ps$0.3 million, or 5%, decrease in installation expenses and cost of disconnected lines.

SG&A:

SG&A expenses were Ps$181.2 million in 3Q07, 9% above Ps$165.9 million in 3Q06. The Ps$15.3 million increase was mainly driven by: (i) higher salaries, wages and benefits of Ps$14.3 million as a result of larger headcount; (ii) Ps$7.2 million higher general and corporate expenses; (iii) Ps$1.3 million higher sales commissions; and, (iv) Ps$0.1 million higher compensation charges related to stock options plans. These increases were partially offset by: (i) lower external advisors expenses of Ps$4.0 million; (ii) Ps$2.4 million lower advertising and promotion expenses; (iii) lower bad debt reserve of Ps$0.9 million; and, (iv) lower maintenance expenses of Ps$0.3 million.

When compared to 2Q07, SG&A expenses in 3Q07 increased 8% from Ps$167.9 million. The Ps$13.2 million increase was generated by: (i) higher salaries, wages and benefits of Ps$12.6 million; (ii) higher general and corporate expenses of Ps$3.1 million; (iii) Ps$1.4 million higher external advisors expense; (iv) Ps$0.9 million higher sales commissions; and, (v) higher compensation charges related to stock options plans of Ps$0.7 million. These increases were partially offset by: (i) Ps$3.5 million decline in advertising and promotion expenses; (ii) lower bad debt reserve of Ps$1.3 million; and, (iii) lower maintenance expenses of Ps$0.7 million.

SG&A expenses in 3Q07, before the effect of the non-cash stock option compensation charge, were Ps$177.0 million, 9% above Ps$161.8 million in 3Q06, and 5% above Ps$167.9 million in 2Q07.

    (1) We define Adjusted EBITDA as net income (loss) excluding depreciation
        and amortization, total integral cost of financing, other (income)
        expenses, special items, tax and stock option plan expense. Adjusted
        EBITDA has material limitations that impair its value as a measure of
        a company's overall profitability since it does not address certain
        ongoing costs of our business that could significantly affect
        profitability such as financial expenses and income taxes,
        depreciation or capital expenditures and associated charges. Adjusted
        EBITDA is not a recognized financial measure under Mexican GAAP or
        U.S. GAAP and do not purport to be an alternative to net income as a
        measure of operating performance or to cash flows from operating
        activity as a measure of liquidity. We believe Adjusted EBITDA can be
        useful to facilitate comparisons of operating performance between
        periods and with other companies because it excludes the effect of
        stock option plan expense, which is a non-cash compensation item. You
        should review EBITDA and Adjusted EBITDA, along with consolidated
        financial statements, when trying to understand our operating
        performance. However, companies define EBITDA and Adjusted EBITDA in
        different ways and caution must be used in comparing these
        measurements to other companies.
