and provides guidance for 2011

	•		Full year 2010 net subscriber additions of 1,641,000 resulting in an ending subscriber base of 9.0 million — a 22% increase over the subscriber base at the end of 2009. Net subscriber additions of 436,000 in the fourth quarter.

RESTON, Va. — February 24, 2011 — NII Holdings, Inc. [NASDAQ: NIHD] today announced its consolidated financial results for the fourth quarter and full year 2010. For the full year 2010, the Company added 1,641,000 net subscribers to its network, bringing its total year-end subscriber base to 9.0 million, a 22% increase over year-end 2009. Financial results for the full year 2010 included consolidated operating revenues of $5.6 billion, a 27% increase compared to last year; consolidated operating income before depreciation and amortization, or OIBDA, of $1.43 billion, a 29% increase compared to last year; and consolidated operating income of $877 million, a 30% increase compared to last year. For the full year 2010, the Company generated net income of $341 million, or $2.03 per basic share. Capital expenditures were $876 million for full year 2010.

For the fourth quarter of 2010, the Company added slightly more than 436,000 net subscribers to its network. Financial results for the fourth quarter of 2010 included consolidated operating revenues of $1.52 billion, a 23% increase over the same period last year, consolidated OIBDA of $379 million, a 27% increase over the same period last year, and consolidated operating income of $229 million, a 31% increase over the same period last year. Consolidated OIBDA results for the fourth quarter of 2010 include an out of period adjustment of $26 million in additional expense resulting from a change in Brazilian tax law that reduced Nextel Brazil’s expected recovery

relating to prepaid Value Added Taxes imposed on handset sales. This out of period adjustment was offset by a benefit of $9 million relating to an operating tax credit in Brazil that was discussed on our third quarter results call but was subsequently excluded from the Company’s reported results for that period. The net effect of these items is a $17 million reduction in the Company’s reported fourth quarter OIBDA.

“NII delivered strong growth and profitability in 2010, exceeding our goals for net subscriber additions, revenues, and OIBDA that we outlined for the year,” said Steve Dussek, NII Holdings’ Chief Executive Officer. “In 2010, we grew our subscriber base by 22%, increased our revenues by 27% and increased our OIBDA by 29%. During 2010, we also successfully bid for 3G spectrum in our largest markets, Mexico and Brazil. We believe our plans to deploy 3G networks will position us to pursue more profitable growth in the future by enabling us to target additional customer segments and provide innovative broadband wireless services to our high value customer base.”

NII Holdings’ consolidated average monthly service revenue per subscriber (ARPU) increased to $48 for the full year 2010 from $45 in 2009, with the increase resulting primarily from higher average currency exchange rates. The Company also reported consolidated churn of 1.66% for the full year 2010, a 35 basis point decrease from the 2.01% churn rate for the full year 2009. Consolidated churn of 1.60% in the fourth quarter was down 25 basis points relative to the same period last year. Consolidated cost per gross add, or CPGA, was $286 for full year 2010, a $10 increase from 2009 levels, resulting primarily from higher average currency exchange rates.

“Our team delivered outstanding results in 2010, capitalizing on a solid rebound in economic activity and driving growth, while generating record levels of profitability,” said Gokul Hemmady, NII’s Executive Vice President and Chief Financial Officer. “The strength of our underlying operations, combined with our plans to use our recently acquired spectrum to deploy new 3G networks, has positioned us to drive success as we compete in a broadband centric world. In 2011, we will commit substantial time and resources to capture this opportunity by building our planned 3G networks, but we will not lose focus on what brought us to where we are today — delivering high quality services that meet the needs of our customers. We believe that our strong liquidity position and flexible capital structure puts us in a great position to execute on all of these opportunities, while maintaining our disciplined approach to capital that has enabled us to be successful in the past.”

The Company ended the year with $2.9 billion in total long-term debt, which includes $1.3 billion in senior notes; $1.1 billion in convertible notes; $194 million in syndicated loan facilities; and $302 million in local currency tower financing obligations, capital leases and other obligations. With year-end consolidated cash and cash equivalents and short-term investments of $2.3 billion, the Company’s net debt at the end of the year was approximately $600 million.

2011 Outlook

The Company announced the following outlook for 2011:

	•		Total net subscriber additions of approximately 1.7 million.
	•		Consolidated operating revenues of approximately $6.6 billion.
	•		Consolidated OIBDA of approximately $1.6 billion, which includes the impact of approximately $50 million of non-cash equity compensation expense. The OIBDA outlook also includes the impact of start up costs related to the development and launch of 3G networks and costs related to support the Company’s 3G initiatives, including marketing related costs and investment in I.T. and other systems to support the expansion of the customer segments targeted for 3G services.

•

Consolidated capital expenditures of approximately $1.6 billion, which includes investments relating to the development and launch of the Company’s 3G networks, costs related to the development of the technology to support high-performance push to talk services on W-CDMA, and the enhancement of the coverage and capacity of the Company’s iDEN networks to support customer growth.

The Company’s 2011 outlook is predicated on a number of assumptions including the assumption that foreign exchange rates and general economic conditions in its markets will remain relatively stable during the year.

In addition to the preliminary results prepared in accordance with accounting principles generally accepted in the United States (GAAP) provided throughout this press release, NII has presented consolidated OIBDA, ARPU, CPGA and Net Debt. These measures are non-GAAP financial measures and should be considered in addition to, but not as substitutes for, the information prepared in accordance with GAAP.

(UNAUDITED)

Operating Income Before Depreciation and Amortization

Consolidated operating income before depreciation and amortization, or OIBDA, represents operating income before depreciation and amortization expense. Consolidated OIBDA is not a measurement under accounting principles generally accepted in the United States, may not be similar to consolidated OIBDA measures of other companies and should be considered in addition to, but not as a substitute for, the information contained in our statements of operations. We believe that consolidated OIBDA provides useful information to investors because it is an indicator of operating performance, especially in a capital intensive industry such as ours, since it excludes items that are not directly attributable to ongoing business operations. Our consolidated OIBDA calculations are commonly used as some of the bases for investors, analysts and credit rating agencies to evaluate and compare the periodic and future operating performance and value of companies within the wireless telecommunications industry. Consolidated OIBDA can be reconciled to our consolidated statements of operations as follows (in millions):

Average Monthly Revenue Per Handset/Unit in Service (ARPU)

Average monthly revenue per handset/unit in service, or ARPU, is an industry term that measures service revenues, which we refer to as subscriber revenues, per period from our customers divided by the weighted average number of handsets in commercial service during that period. ARPU is not a measurement under accounting principles generally accepted in the United States, may not be similar to ARPU measures of other companies and should be considered in addition, but not as a substitute for, the information contained in our statements of operations. We believe that ARPU provides useful information concerning the appeal of our rate plans and service offerings and our performance in attracting and retaining high value customers. Other revenue includes revenues for such services as roaming, handset maintenance, cancellation fees, analog and other. ARPU can be calculated and reconciled to our consolidated statement of operations as follows (in millions, except ARPU):

Cost per Gross Add (CPGA)

Cost per gross add, or CPGA, is an industry term that is calculated by dividing our selling, marketing and handset and accessory subsidy costs, excluding costs unrelated to initial customer acquisition, by our new subscribers during the period, or gross adds. CPGA is not a measurement under accounting principles generally accepted in the United States, may not be similar to CPGA measures of other companies and should be considered in addition, but not as a substitute for, the information contained in our statements of operations. We believe CPGA is a measure of the relative cost of customer acquisition. CPGA can be calculated and reconciled to our consolidated statements of operations as follows (in millions, except CPGA):

Net Debt

Net debt represents total long-term debt less cash, cash equivalents, short-term and long-term investments. Net debt to consolidated operating income before depreciation and amortization represents net debt divided by consolidated operating income before depreciation and amortization. Prior to 2008, we calculated net debt as total long-term debt less cash and cash equivalents. In the second quarter of 2010, we extended the permissible investment maturity dates for cash investments, which resulted in the classification of some of our cash investments as long-term investments. As a result, we now include the cash in long-term investments to the items subtracted from long-term debt to calculate net debt. Net debt is not a measurement under accounting principles generally accepted in the United States, may not be similar to net debt measures of other companies and should be considered in addition to, but not as a substitute for, the information contained in our balance sheets. We believe that net debt and net debt to consolidated operating income before depreciation and amortization provide useful information concerning our liquidity and leverage. Net debt as of December 31, 2010 can be calculated as follows (in millions):
