RESTON, Va., May 10, 2017 - NII Holdings, Inc. [NASDAQ: NIHD] today announced its financial results for the first quarter of 2017. For the quarter, the Company generated consolidated operating revenues of $251 million, consolidated adjusted OIBDA of $5 million and a consolidated operating loss of $80 million. The Company’s consolidated adjusted OIBDA excludes the impact of non-cash asset impairments, restructuring charges and other unusual items. Capital expenditures were $9 million for the quarter. The Company reported 3G net subscriber additions of 38,000 in the quarter, which were offset by 115,000 subscriber losses on the Company's iDEN network.

“We had solid results to start off the year,” said Steve Shindler, NII’s Chief Executive Officer. “We reported our fifth consecutive quarter of positive adjusted OIBDA in Brazil and our second consecutive quarter of more than 35,000 3G net subscriber additions, resulting from a continued reduction in churn. We had a slight drop in ARPU compared to last quarter primarily due to increased customer credits, which we expect to continue to offer as a retention tool.”

Nextel Brazil's average monthly service revenue per subscriber (ARPU) for the first quarter of 2017 was $21, a 31% increase on a reported basis, and a 5% increase on a constant currency basis, compared to the same quarter last year. Nextel Brazil's average monthly churn rate for the first quarter of 2017 was 3.71%, a 63 basis point decrease compared to the same quarter last year. Nextel Brazil's cost per gross addition (CPGA) was $84 for the first quarter of 2017, a $12 decrease on a reported basis, and a 28% decrease on a constant currency basis, compared to the same quarter last year. Nextel Brazil's cash cost per user (CCPU) was $19 for the first quarter of 2017, a $4 increase on a reported basis, and a 1% decrease on a constant currency basis, compared to the same quarter last year.

During the first quarter, the Company spent $118 million of cash and investments, primarily related to $45 million of cash used in operating activities (including approximately $30 million paid for interest and $19 million paid for annual spectrum license fees), $28 million of cash used for capital expenditures and $42 million of cash for scheduled principal payments.

At quarter-end, the Company's sources of funding included $213 million of cash and short-term investments, $163 million of cash held in escrow to secure indemnification obligations in connection with the sale of Nextel Mexico and $92 million in cash pledged as collateral to secure certain performance bonds in Brazil.

“We are making good progress working with our lenders to obtain multiple years of principal amortization relief on our loans,” said Dan Freiman, NII’s Chief Financial Officer. “Our ongoing discussions reflect a common interest in making the necessary modifications to our loan terms to allow adequate time for us to continue to build the scale in our business we need to generate free cash flow. We're optimistic that we will reach an agreement with our lenders.”

Additional details regarding the Company’s results, including a more detailed explanation on local currency operating metrics, are included in the Company’s Quarterly Report on Form 10-Q for the three months ended March 31, 2017 that wasfiled with the Securities and Exchange Commission today.

(UNAUDITED)

Consolidated OIBDA and Consolidated Adjusted OIBDA

Consolidated operating income before depreciation and amortization, or OIBDA, represents operating income before depreciation and amortization expense. Consolidated adjusted operating income before depreciation and amortization, or adjusted OIBDA, represents consolidated operating income before depreciation expense, amortization expense, material asset impairments, severance costs associated with publicly announced restructuring plans and other material non-recurring or unusual charges. Consolidated OIBDA and consolidated adjusted OIBDA are not measurements under accounting principles generally accepted in the United States, may not be similar to consolidated OIBDA and consolidated adjusted OIBDA measures of other companies and should be considered in addition to, but not as substitutes for, the information contained in our statements of operations. We believe that consolidated OIBDA and consolidated adjusted OIBDA provide useful information to investors because they are indicators of our operating performance, especially in a capital intensive industry such as ours, since they exclude items that are not directly attributable to ongoing business operations. Consolidated OIBDA and consolidated adjusted 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 subscriber 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 subscriber units 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 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 as follows (in millions, except CPGA):

Cost per Gross Add	$	264		$	369

Cash Cost per Handset/User

Cash cost per handset/unit, or CCPU, represents the sum of cost of service, general and administrative expenses and customer retention and other costs divided by average handsets in service during the period and divided by the number of months in the period. CCPU is not a measurement under accounting principles generally accepted in the United States, may not be similar to CCPU measures of other companies and should not be considered in addition to, but not as a substitute for, the information contained in our statements of operations. We believe CCPU is a measure of the recurring costs we incur on a monthly basis to provide service to our subscribers. The CCPU calculation excludes material asset impairments, severance costs associated with publicly announced restructuring plans and other material non-recurring or unusual charges and is calculated as follows (in thousands, except CCPU):

Impact of Foreign Currency Fluctuations

The following table shows the impact of changes in foreign currency exchange rates on certain financial measures for the three months ended March 31, 2016 compared to the same period in 2017 by (i) adjusting the relevant measures for the three months ended March 31, 2016 to levels that would have resulted if the average foreign currency exchange rates for the three months ended March 31, 2016 were the same as the average foreign currency exchange rates that were in effect for the three months ended March 31, 2017; and (ii) comparing the actual and adjusted financial measures for the three months ended March 31, 2016 to the similar financial measures for the three months ended March 31, 2017 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 on a consolidated basis and segment earnings for Nextel Brazil, before the adjustments for changes in foreign currency exchange rates, are based on the calculations contained elsewhere in these non-GAAP reconciliations for the three months ended March 31, 2017 and 2016. The average foreign currency exchange rates for each of the relevant currencies during each of the three months ended March 31, 2017 and 2016 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 three months ended March 31, 2017 compared to the same period in 2016 by removing the impact of the significant difference in the average foreign currency exchange rates in effect for those periods.
