• Full year 2009 consolidated operating revenues of $4.4 billion — a 3% increase over 2008. Consolidated fourth quarter operating revenues of $1.2 billion.

RESTON, Va. — February 25, 2010 — NII Holdings, Inc. [NASDAQ: NIHD] today announced its consolidated financial results for the fourth quarter and full year 2009. For the full year 2009, the Company added 1,185,000 net subscribers to its network, bringing the total year-end subscriber base to 7.4 million, a 20% increase in the ending subscriber base over year-end 2008. Financial results for the full year 2009 included consolidated operating revenues of $4.40 billion, a 3% increase compared to last year; consolidated operating income before depreciation and amortization, or OIBDA, of $1.11 billion, a 5% decrease compared to last year; and consolidated operating income of $677 million, a 12% decrease compared to last year. For the full year 2009, the Company generated net income of $381 million, or $2.30 per basic share. During 2009, the Company expanded its network coverage to an estimated 15 million additional people primarily in Brazil. Capital expenditures were $733 million for full-year 2009.

For the fourth quarter of 2009, the Company added over 347,000 net subscribers to its network. Financial results for the fourth quarter of 2009 included consolidated operating revenues of $1.23 billion, a 25% increase over the same period last year, consolidated OIBDA of $298 million, a 19% increase over the same period last year, and consolidated operating income of $175 million, an 11% increase over the same period last year. Consolidated OIBDA results for the fourth quarter of 2009 include $27 million in severance costs related to the transition of our employees in connection with the previously announced network operations and IT managed services contracts.

“NII delivered strong growth and profitability in 2009, meeting or exceeding our goals for net subscriber additions, revenues, and OIBDA that we outlined for the year,” said Steve Dussek, NII Holdings’ Chief Executive Officer. “For the year we grew our subscriber base by 20%, and when comparing our results on a constant currency basis, we increased our revenues by 19% and increased our OIBDA by 25%. We expanded our network to about 15 million additional people during the year, with most of that expansion in Brazil. We believe these investments will continue to enhance our brand and visibility, positioning NII to generate more profitable growth in the future. We are also very excited about the previously announced agreements that we entered into with Nokia Siemens Networks and Hewlett Packard for managed services of our network support and information technology operations, respectively. We believe that our partnerships with these world class companies will position us to further enhance the superior service quality our high value customers have come to expect, while improving our efficiency,” he added.

NII Holdings’ consolidated average monthly service revenue per subscriber (ARPU) was $45 for the full year 2009, a decline compared to 2008 that is primarily the result of lower average currency exchange rates. The Company also reported churn of 2.0% for the full year 2009, an increase from the 1.9% churn rate for the full year 2008, but reported churn of 1.85% in the fourth quarter of 2009, which was flat relative to the churn rate reported in the fourth quarter of 2008. Consolidated cost per gross add, or CPGA, was $271 for full year 2009 — a $39 improvement over 2008, resulting primarily from lower average currency exchange rates.

“Our team again delivered outstanding results, adjusting to rapidly changing economic conditions throughout the year and executing on our plan to deliver profitable growth in a difficult economic environment,” said Gokul Hemmady, NII’s Vice President and Chief Financial Officer. “We will continue to pursue strategies that are designed to provide the flexibility we need to respond to changes in the economic and competitive environment and that position us to deliver on our profitable growth strategy. We are excited about the opportunities that are available to us in 2010, including our plans to pursue spectrum, and if successful, support our deployment of 3G networks in our markets. We believe our strong liquidity position and flexible capital structure put us in a great position to pursue these opportunities, all while maintaining our disciplined approach to capital allocation that has enabled us to be successful in the past.”

The Company ended the year with approximately $3.49 billion in total long-term debt, which includes $1.3 billion in senior notes, $1.2 billion in convertible notes, $350 million in convertible notes classified as short-term debt, $335 million in syndicated loan facilities, and $306 million in local currency tower financing obligations, capital leases and other obligations. With year-end consolidated cash and cash equivalents of $2.5 billion and short-term investments of $116 million, the Company’s net debt at the end of the year was $871 million.

On February 15, 2010, the Company also announced that it signed an investment agreement under which Grupo Televisa, S.A.B. will invest $1.44 billion in cash for an initial 30% equity stake in NII Holding’s operating subsidiary in Mexico. Televisa will also be granted an option to acquire an additional 7.5% equity interest in Nextel Mexico that will be exercisable on either the 3^rd or 4^th anniversary of the completion of the initial investment. Pursuant to this investment agreement, the parties agreed to form a bidding consortium to participate together in the spectrum auctions in Mexico that are expected to be conducted during the first half of 2010. Completion of the transactions contemplated by the investment agreement, including Televisa’s acquisition of the

equity interest in Nextel Mexico, is conditioned upon, among other things, the consortium’s success in the spectrum auctions.

2010 Outlook

The Company announced the following outlook for 2010:

• Total net subscriber additions in the range of 1.275 million to 1.375 million.

• Consolidated operating revenues in the range of $5.2 billion to $5.4 billion.

• Consolidated OIBDA in the range of $1.25 billion to $1.35 billion, which includes the impact of approximately $75 million of non-cash equity compensation expense. The OIBDA outlook also includes the impact of ongoing start up costs related to the launch of the Company’s third generation network in Peru, start up costs related to the development of the Company’s third generation network in Chile, and costs related to market launch of 7 million additional POPs.

• Consolidated capital expenditures in the range of $850 million to $950 million, which includes investments relating to the development of the Company’s third generation network in Chile, and the enhancement of the coverage and capacity of our network in Brazil.

The Company’s 2010 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 information based on consolidated operating revenues and consolidated OIBDA for 2009 that are compared with the results for 2008 on a constant currency basis, which adjusts the results by using the same average currency exchange rates for the full years 2009 and 2008, and has presented consolidated OIBDA, ARPU, CPGA and Net Debt. These measures and the constant currency comparisons are non-GAAP financial measures and should be considered in addition to, but not as substitutes for, the information prepared in accordance with GAAP. Reconciliations from GAAP results to these non-GAAP financial measures are provided in the notes to the attached financial table.

Consolidated 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):

* The Company’s guidance estimate for OIBDA for the year ended December 31, 2010 includes the impact of approximately $75 million of non-cash equity compensation expense. This estimate is predicated on a number of assumptions, including the assumption that foreign currency exchange rates and general economic conditions in its markets will remain relatively stable during the year. The information regarding the Company’s outlook and objectives for 2010, including its guidance estimate for OIBDA for the year ended December 31, 2010, is forward looking and is based upon management’s current beliefs, as well as a number of assumptions concerning future events, and as such, should be taken in the context of the risks and uncertainties identified in the “Safe Harbor” Statement under the Private Securities Litigation Reform Act of 1995 included above and of the risks and uncertainties outlined in the SEC filings of NII Holdings, Inc., including the Company’s Annual Report on Form 10-K for the year ended December 31, 2008, the Company’s Current Report on Form 8-K dated August 5, 2009 and the Company’s other filings with the SEC.

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 and short-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 2008, we added short-term investments to the items subtracted from long-term debt to calculate net debt because we concluded that our short-term investments were similar to cash and cash equivalents in terms of liquidity and should be used similarly in providing the assessment of our overall leverage in the net debt calculation. 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, 2009 can be calculated as follows (in millions):

Impact of Foreign Currency Fluctuations

The following table shows the impact of changes in foreign currency exchange rates on certain financial measures from the year ended December 31, 2008 to the year ended December 31, 2009 by (i) adjusting the relevant measures for the year ended December 31, 2008 to levels that would have resulted if the average foreign currency exchange rates for the year ended December 31, 2008 were the same as the average foreign currency exchange rates that were in effect for the year ended December 31, 2009 and (ii) by comparing the actual and adjusted 2008 financial measures to the similar financial measures for the year ended December 31, 2009 to show the percentage change in those measures before and after taking those adjustments into account. The amounts reflected in the following table for operating income before depreciation and amortization and average monthly revenue per handset/unit in service on a consolidated basis and for Nextel Mexico, Nextel Brazil and Nextel Argentina, before the adjustments for changes in foreign currency exchange rates, are based on the calculations contained elsewhere in these non-GAAP reconciliations for the years and three months ended December 31, 2009 and 2008. The average foreign currency exchange rates for each of the relevant currencies during each of the years ended December 31, 2009 and 2008 are included in the notes to the table below. The information reflected in the following table 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. We believe that these calculations provide useful information concerning our relative performance for the year ended December 31, 2008 compared to the year ended December 31, 2009 by removing the impact of the significant difference in the average foreign currency exchange rates in effect for those periods.

(1) The 2008 Normalized amounts reflect the impact of applying the monthly average foreign currency exchange rates for each of the twelve months ended December 31, 2009 to the operating revenues earned in foreign currencies and to the other components of each of the 2008 actual financial measures shown above for the year ended December 31, 2008, other than certain components of those measures consisting of U.S. dollar-based operating expenses, which were not adjusted. The amounts included under the column “2008 Adjustment” reflect the amount determined by subtracting the 2008 Normalized amounts calculated as described in the preceding sentence from the 2008 Actual amounts and reflect the impact of the year over year change in the average foreign currency exchange rates on each of the financial measures for 2008. The average foreign currency exchange rates for each of the relevant currencies during each of the twelve months ended December 31, 2009 and 2008 for purposes of these calculations were as follows:
