NII HOLDINGS, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Basis of Presentation

Unless the context requires otherwise, "NII Holdings, Inc.," "NII Holdings," "we," "our," "us" and "the Company" refer to the combined businesses of NII Holdings, Inc. and its consolidated subsidiaries. Our unaudited condensed consolidated financial statements have been prepared under the rules and regulations of the Securities and Exchange Commission, or the SEC. While these financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements, they reflect all adjustments that, in the opinion of management, are necessary for a fair presentation of the results for interim periods. In addition, the year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. We refer to our wholly-owned Brazilian operating company, Nextel Telecomunicações Ltda., as Nextel Brazil.

You should read these condensed consolidated financial statements in conjunction with the consolidated financial statements and notes contained in our annual report on Form 10-K for the year ended December 31, 2015. You should not expect results of operations for interim periods to be an indication of the results for a full year. Our consolidated results from continuing operations in this quarterly report on Form 10-Q include the results of operations of Nextel Brazil and our corporate headquarters.

Revision of Prior Period Financial Statements. In connection with the preparation of our condensed consolidated financial statements for the three months ended March 31, 2016, we determined that an error existed in our previously issued financial statements. Specifically, selling, general and administrative expenses for the six months ended December 31, 2015 were understated by $6.9 million as the result of a failure to properly accrue expenses for services Nextel Brazil received under a management consulting services arrangement. We evaluated this error under the SEC's authoritative guidance on materiality and the quantification of the effect of prior period misstatements on financial statements, and we have determined that the impact of this error on our prior period consolidated financial statements is immaterial. However, since the correction of this error in the first quarter of 2016 would have been material to our results of operations for the three months ended March 31, 2016 and may be material to our results of operations for the year ending December 31, 2016, we revised our prior period financial statements to correct this error herein. 

As a result of the correction of this error, as of December 31, 2015, accrued expenses and other increased by $6.8 million, accumulated deficit increased by $6.9 million and accumulated other comprehensive loss decreased by $0.1 million. Although not presented herein, for the six months ended December 31, 2015, this error resulted in a $6.9 million increase to selling, general and administrative expenses, operating loss, loss from continuing operations before reorganization items and income tax benefit, net loss from continuing operations and net loss. In addition, for the six months ended December 31, 2015, the correction of this error also resulted in a $0.07 increase in both net loss from continuing operations per basic and diluted common share and net loss per basic and diluted common share. This error did not relate to any periods prior to the six months ended December 31, 2015.

Sales of Nextel Argentina and Nextel Mexico. On April 30, 2015, we completed the sale of our operations in Mexico to New Cingular Wireless, Inc., or New Cingular Wireless, an indirect subsidiary of AT&T, Inc., or AT&T. In addition, on September 11, 2015, two of our indirect subsidiaries entered into a binding agreement with Grupo Clarin S.A., or Grupo Clarin, relating to the sale of all of the outstanding equity interests of Nextel Argentina, which was completed on January 27, 2016. See Note 4 for more information on these sales. In connection with these transactions, we have presented Nextel Argentina's and Nextel Mexico's results for all periods as discontinued operations in this quarterly report on Form 10-Q.

Reorganization Accounting. In accordance with the requirements of reorganization accounting, NII Holdings adopted the provisions of fresh start accounting as of June 30, 2015 and became a new entity for financial reporting purposes. References to the "Successor Company" relate to NII Holdings on or subsequent to June 30, 2015. References to the "Predecessor Company" relate to NII Holdings prior to June 30, 2015. See Note 2 for more information regarding the implementation of fresh start accounting.

Going Concern.The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. These condensed consolidated financial statements do not include any adjustments that might result from the occurrence of the uncertainties described below.

We have an obligation to meet a net debt financial covenant in Nextel Brazil's local bank loans that will apply semiannually beginning on June 30, 2016. We have made a number of changes within our senior management team and modified our business plan to reflect our available cash resources and the impact of the current and expected economic and competitive conditions in Brazil on both our subscriber growth and revenues, and to align our costs with this revised outlook, but based on our current business plan, we believe that it is unlikely that we will satisfy the applicable financial covenant included in both of Nextel Brazil's local bank loan agreements at the June 30, 2016 measurement date. We will need to refinance or negotiate amendments to these

(Unaudited)

financing arrangements or secure waivers from the lenders in order to avoid a potential default under the loan agreements. If a default occurs, the lenders could require us to repay the amounts outstanding under these arrangements, and if they were to do so, the lender of Nextel Brazil's equipment financing facility could accelerate the amount outstanding under that obligation as well. As of March 31, 2016, we had $256.5 million principal amount outstanding under Nextel Brazil's local bank loans and $318.0 million principal amount outstanding under Nextel Brazil’s equipment financing facility. See Note 6 for more information.

Because it is unlikely that we will satisfy the applicable financial covenant included in both of Nextel Brazil's local bank loans and because of the cross-default provisions included in Nextel Brazil's equipment financing facility as described above, we concluded that the circumstances described above continue to raise substantial doubt about our ability to continue as a going concern as of March 31, 2016.

Reclassifications. We have reclassified some prior period amounts in our condensed consolidated financial statements to conform to our current year presentation.

New Accounting Pronouncements.  In March 2016, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update, or ASU, No. 2016-09, “Improvements to Employee Share-Based Payment Accounting,” which includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. We early adopted this ASU in the first quarter of 2016. Under the new guidance, we made an accounting policy election to recognize the impact of forfeited awards on compensation expense when they occur, rather than initially reducing expense for an estimate of future forfeitures. This policy was applied using a modified retrospective approach and resulted in an immaterial cumulative effect adjustment to retained earnings.

Note 2. Emergence from Chapter 11 Proceedings and Fresh Start Accounting

On September 15, 2014, we and eight of our U.S. and Luxembourg-domiciled subsidiaries, including NII Capital Corp. and NII International Telecom, S.C.A., or NIIT, filed voluntary petitions seeking relief under Chapter 11 of Title 11 of the United States Bankruptcy Code, which we refer to as Chapter 11, in the United States Bankruptcy Court for the Southern District of New York, which we refer to as the Bankruptcy Court. In addition, subsequent to September 15, 2014, five additional subsidiaries of NII Holdings, Inc. filed voluntary petitions seeking relief under Chapter 11 in the Bankruptcy Court. We refer to the companies that filed voluntary petitions seeking relief under Chapter 11 collectively as the Debtors. Nextel Brazil and our previous other operating subsidiaries in Latin America were not Debtors in these Chapter 11 cases.

On June 19, 2015, the Bankruptcy Court entered an order approving and confirming the First Amended Joint Plan of Reorganization Proposed by the Plan Debtors and the Official Committee of Unsecured Creditors, dated April 20, 2015. We refer to this plan, as amended, as the Plan of Reorganization. On June 26, 2015, the conditions of the Bankruptcy Court's order and the Plan of Reorganization were satisfied, the Plan of Reorganization became effective, and we and the other Debtors emerged from the Chapter 11 proceedings. We refer to June 26, 2015 as the Emergence Date.

The significant transactions that occurred on the Emergence Date in connection with the effectiveness of our Plan of Reorganization included the following:

• NII Holdings canceled all shares of its common stock, preferred stock and other equity interests that existed prior to June 26, 2015;

• NII Holdings amended and restated its Bylaws and filed an Amended and Restated Certificate of Incorporation authorizing the Company to issue up to 140,000,000 shares of common stock, par value $0.001 per share, and up to 10,000,000 shares of undesignated preferred stock, par value $0.001 per share;

• NII Holdings issued 99,999,992 shares of new common stock, with a per share value of $20.68, and distributed cash of $776.3 million to the holders of claims and service providers in comprehensive settlement of numerous integrated claims and disputes approved by the Bankruptcy Court in connection with the confirmation of the Plan of Reorganization;

• In accordance with the Plan of Reorganization, all of the obligations of the Debtors with respect to the following indebtedness were canceled:

• $700.0 million aggregate principal amount of 7.875% senior notes due 2019 issued by NIIT pursuant to an indenture, dated as of May 23, 2013, among NIIT (as issuer), the Company (as guarantor), and Wilmington Trust National Association (as trustee) and all amendments, supplements or modifications thereto and extensions thereof;

• $900.0 million aggregate principal amount of 11.375% senior notes due 2019 issued by NIIT pursuant to an indenture, dated as of February 19, 2013, among NIIT (as issuer), the Company (as guarantor), and Wilmington Trust National Association (as trustee) and all amendments, supplements or modifications thereto and extensions thereof;

• $1.45 billion aggregate principal amount of 7.625% senior notes due 2021 issued by NII Capital Corp. pursuant to an indenture, dated as of March 29, 2011, among NII Capital Corp. (as issuer), each of the guarantors party thereto and Wilmington Savings Fund Society, FSB (as successor trustee) and all amendments, supplements or modifications thereto and extensions thereof;

• $500.0 million aggregate principal amount of 8.875% senior notes due 2019 issued by NII Capital Corp. pursuant to an indenture, dated as of December 15, 2009, among NII Capital Corp. (as issuer), each of the guarantors party thereto and U.S. Bank National Association (as successor trustee) and all amendments, supplements or modifications thereto and extensions thereof; and

• $800.0 million aggregate principal amount of 10.0% senior notes due 2016 issued by NII Capital Corp. pursuant to an indenture, dated as of August 18, 2009, among NII Capital Corp. (as issuer), each of the guarantors party thereto and Wilmington Savings Fund Society, FSB (as successor trustee) and all amendments, supplements or modifications thereto and extensions thereof.

In connection with our emergence from Chapter 11, we were required to apply the provisions of fresh start accounting to our financial statements. Because our results of operations during the period from June 26, 2015 to June 30, 2015 were not material, we applied fresh start accounting to our consolidated financial statements as of the close of business on June 30, 2015. Under the principles of fresh start accounting, a new reporting entity is considered to be created, and as a result, we allocated the reorganization value of NII Holdings as of June 30, 2015 to our individual assets based on their estimated fair values at the date we applied fresh start accounting.

Reorganization items for the three months ended March 31, 2016 were immaterial. Reorganization items for the three months ended March 31, 2015 consisted of $13.6 million in Chapter 11-related professional fees and other costs.

In connection with the completion of the sale of Nextel Communications Argentina, S.R.L., or Nextel Argentina, to Grupo Clarin in January 2016, the promissory note that was initially issued in connection with this transaction was canceled. See Note 4 for more information. Other than the cancellation of this promissory note in the first quarter of 2016, we did not have any non-cash investing or financing activities during the three months ended March 31, 2016 or 2015.

Revenue-Based Taxes. We record certain revenue-based taxes and other excise taxes on a gross basis as a component of both service and other revenues and selling, general and administrative expenses in our condensed consolidated financial statements. For the three months ended March 31, 2016 and 2015, we recognized $13.7 million and $17.8 million, respectively, in revenue-based taxes and other excise taxes, respectively.

Diluted Net Loss Per Common Share. As presented for the three months ended March 31, 2016 and 2015, our calculation of diluted net loss from continuing operations per common share is based on the weighted average number of common shares outstanding during those periods and does not include other potential common shares, including shares issuable upon the potential exercise of stock options under our stock-based employee compensation plans or restricted common shares issued under those plans since their effect would have been antidilutive.

For the three months ended March 31, 2016, we did not include 3.7 million stock options and 0.9 million restricted common shares in our calculation of diluted net loss from continuing operations per common share because their effect would have been antidilutive. In addition, for the three months ended March 31, 2015, we did not include 5.3 million stock options and 0.7 million restricted common shares in our calculation of diluted net loss from continuing operations per common share because their effect would have been antidilutive.

Note 4. Discontinued Operations

Sale of Nextel Argentina. On September 11, 2015, NII Mercosur Telecom, S.L.U. and NII Mercosur Moviles, S.L.U., both of which are indirect subsidiaries of NII Holdings, entered into a binding agreement with Grupo Clarin relating to the sale of all of the outstanding equity interests of Nextel Argentina. This agreement provided for aggregate cash consideration of $178.0 million, of which $159.0 million was paid at signing in connection with the transfer of a 49% equity interest in Nextel Argentina and the grant of a call option that allowed Grupo Clarin or any of its affiliates to acquire the remaining 51% equity interest in Nextel Argentina upon receipt of required approvals from the regulatory authorities in Argentina. We received the remaining cash consideration in October 2015, including $6.0 million deposited in escrow to satisfy potential indemnification claims. On January 27, 2016, the agreement was amended to permit Grupo Clarin or any of it affiliates to exercise the right to acquire the remaining 51% equity interest prior to receiving regulatory approval, and Grupo Clarin and its affiliates immediately acquired the remaining 51% of Nextel Argentina for no additional proceeds.

Sale of Nextel Mexico. On April 30, 2015, we, together with our wholly-owned subsidiary NIU Holdings LLC, completed the sale of our Mexican operations to New Cingular Wireless, an indirect subsidiary of AT&T. The transaction was structured as a sale of all of the outstanding stock of the parent company of Comunicaciones Nextel de Mexico, S.A. de C.V., or Nextel Mexico, for a purchase price of $1.875 billion, including $187.5 million deposited in escrow to satisfy potential indemnification claims. The net proceeds from this sale were $1.448 billion after deducting Nextel Mexico's outstanding indebtedness and applying other specified price adjustments. The amount held in escrow is available for the indemnification of defined claims through April 2017.

As of March 31, 2016, we had received notification for one indemnification claim in the amount of $6.5 million. As of March 31, 2016, we accrued an immaterial amount related to the potential settlement of this claim. We intend to vigorously contest this claim.

Sale of Nextel Chile. In August 2014, our wholly-owned subsidiaries NII Mercosur Telecom, S.L., NII Mercosur Moviles, S.L. and NII International Telecom S.C.A. completed the sale of all of the outstanding equity interests in our wholly-owned subsidiary, Nextel Chile, S.A., or Nextel Chile, to Fucata, S.A., a venture comprised of Grupo Veintitres and Optimum Advisors, for a de minimus amount.

Sale of Nextel Peru. In August 2013, our wholly-owned subsidiaries NII Mercosur Telecom, S.L. and NII Mercosur Moviles, S.L., completed the sale of all of the outstanding equity interests of our wholly-owned subsidiary, Nextel del Peru, S.A., or Nextel Peru, to Empresa Nacional de Telecomunicaciones S.A. and one of its subsidiaries, Entel Inversiones, S.A., which we refer to collectively as Entel. Entel has provided notice of potential claims for amounts greater than the $34.4 million that remained in escrow as of March 31, 2016 to satisfy these claims. We believe that the requirements for payment of certain indemnification claims have not been met at this time, and we intend to vigorously contest these claims. As of March 31, 2016, we accrued an immaterial amount related to the potential settlement of these claims. The time period for additional claims against the amount held in escrow lapsed in February 2015.

In connection with the sales of Nextel Argentina and Nextel Mexico, we have reported the results of these operating companies as discontinued operations in this quarterly report on Form 10-Q. Accordingly, we reclassified Nextel Argentina's and Nextel Mexico's results of operations for all periods presented to reflect these former operating companies as discontinued operations. Unless otherwise noted, amounts included in these notes to our condensed consolidated financial statements exclude amounts attributable to discontinued operations. The major components of loss from discontinued operations related to Nextel Argentina and Nextel Mexico were as follows (in thousands):

Note 5. Impairment, Restructuring and Other Charges

Asset Impairments.

During the first quarter of 2016, we reviewed our Nextel Brazil segment for potential impairment using a probability-weighted cash flow analysis. Our estimation of undiscounted future cash flows was partially based on assumptions that we will be able to fund our business plan and that it is not probable that our Nextel Brazil segment will be disposed of. Based on our current estimated undiscounted future cash flows, we determined that the carrying value of our Nextel Brazil segment is recoverable. 

During the three months ended March 31, 2015, Nextel Brazil recognized $3.7 million in non-cash asset impairment charges, the majority of which related to the shutdown or abandonment of certain transmitter and receiver sites that are no longer required in its business.

Restructuring Charges.

During the three months ended March 31, 2016, we recognized $1.3 million in severance and other related costs at the corporate level as a result of the separation of employees in an effort to streamline our organizational structure and reduce general and administrative expenses. During the three months ended March 31, 2016, Nextel Brazil recognized $3.2 million in restructuring charges primarily related to future lease costs for certain transmitter and receiver sites that are no longer required in its business and certain office closures. Nextel Brazil recognized $2.0 million in restructuring charges during the three months ended March 31, 2015 related to similar streamlining and cost reduction efforts.

Total impairment, restructuring and other charges for the three months ended March 31, 2016 and 2015 were as follows (in thousands):

Note 6. Debt

As a result of the implementation of fresh start accounting in connection with our emergence from Chapter 11, we remeasured the components of our debt to their fair values as of June 30, 2015. As a result, the carrying values of our bank loans and equipment financing facility do not represent their respective outstanding principal balances. The components of our debt are as follows:

	Successor Company

Brazil Bank Loans. In February 2015, Nextel Brazil and the lenders providing its local bank loans entered into standstill amendments which provided for a "covenant holiday" through December 31, 2015, during which time we were not required to comply with the financial covenants outlined in Nextel Brazil's local bank loan agreements. Going forward, Nextel Brazil must maintain a net debt to earnings before interest, taxes, depreciation and amortization, or EBITDA, ratio over the trailing 12 months of no greater than 4.0 as of June 30, 2016, 3.5 as of December 31, 2016 and 2.5 as of June 30, 2017 and on each six-month anniversary thereafter.

In connection with our emergence from Chapter 11, we made a number of changes within our senior management team and modified our business plan to reflect our available cash resources and the impact of the current and expected economic and competitive conditions in Brazil on both our subscriber growth and revenues, and to align our costs with this revised outlook. Based on our current business plan, we believe that it is unlikely that we will satisfy the applicable financial covenant included in both of Nextel Brazil's local bank loan agreements at the June 30, 2016 measurement date.

We will need to refinance or negotiate amendments to these financing arrangements or secure waivers from the lenders in order to avoid a potential default under the loan agreements. If a default occurs, the lenders could require us to repay the amounts outstanding under these arrangements. As a result of this uncertainty, we have continued to classify the amounts outstanding under Nextel Brazil's local bank loans as current liabilities in our condensed consolidated balance sheet as of March 31, 2016. As of March 31, 2016, we had $256.5 million principal amount outstanding under Nextel Brazil's local bank loans.

Brazil Equipment Financing Facility. In December 2014, Nextel Brazil and the lender under its equipment financing facility agreed to amend this facility to remove all financial covenants beginning with the December 31, 2014 measurement date through the June 30, 2017 measurement date so that the first measurement date under the amended facility will be December 31, 2017. Because of the uncertainty regarding our ability to meet the financial covenant contained in Nextel Brazil's local bank loans discussed above and certain cross-default provisions that are included in the loan agreement under Nextel Brazil's equipment financing facility, we have continued to classify the amount outstanding under this facility as a current liability in our condensed consolidated balance sheet as of March 31, 2016. As of March 31, 2016, we had $318.0 million in principal amount outstanding under Nextel Brazil's equipment financing facility. We do not have the ability to borrow additional amounts under this equipment financing facility.

Note 7. Fair Value Measurements

Nextel Argentina.

On September 11, 2015, two of our indirect subsidiaries entered into a binding agreement with Grupo Clarin relating to the sale of all of the outstanding equity interests of Nextel Argentina. In connection with the initial agreement, we issued a non-recourse promissory note in the amount of $85.0 million and pledged the remaining 51% of the equity interests in Nextel Argentina to Grupo Clarin. As of December 31, 2015, we recorded our retained 51% interest in Nextel Argentina as an equity method investment under the fair value option, which was included as a component of other assets in our consolidated balance sheet. As of December 31, 2015, we estimated the fair value of this investment to be $108.1 million. In addition, as of December 31, 2015, we recorded the non-recourse promissory note as a component of other long-term liabilities in our consolidated balance sheet at its estimated fair value of $108.1 million. This fair value estimate was based on the $178.0 million purchase price paid by Grupo Clarin, as adjusted for changes in excess cash from September 11, 2015 through December 31, 2015. On January 27, 2016, the agreement was amended to permit Grupo Clarin or any of its affiliates to exercise the right to acquire the remaining 51% equity interest prior to receiving regulatory approval, and Grupo Clarin and its affiliate immediately acquired the remaining 51% of Nextel Argentina for no additional proceeds. In connection with the completion of this transaction, the promissory note was canceled on January 27, 2016.

Financial Instruments.

Available-for-Sale Securities.

As of March 31, 2016 and December 31, 2015, available-for-sale securities held by Nextel Brazil included $23.7 million and $56.2 million, respectively, in investment funds and $10.5 million and $9.3 million, respectively, in certificates of deposit with a Brazilian bank. These funds invest primarily in Brazilian government bonds, long-term, low-risk bank certificates of deposit and Brazilian corporate debentures. During the three months ended March 31, 2016 and 2015, we did not have any material unrealized gains or losses associated with these investments.

We account for our available-for-sale securities at fair value. The fair value of our Brazilian certificates of deposit is based on their current redemption amount, and we classify these certificates of deposit within Level 2 of the fair value hierarchy. The fair value of Nextel Brazil's investment funds is measured based on the funds' net asset value as a practical expedient, which is excluded from the fair value hierarchy.

Held-to-Maturity Investments.

We periodically invest some of our cash holdings in certain securities that we intend to hold to maturity. As of December 31, 2015, held-to-maturity investments included $18.1 million in short-term investments held by NIIT in U.S. treasury notes. We account for held-to-maturity securities at amortized cost, which approximates the fair value observed in the market. As of December 31, 2015, the fair value of our held-to-maturity investments was $18.0 million. These securities matured in February 2016.

Debt Instruments.

The carrying amounts and estimated fair values of our debt instruments are as follows:

	Successor Company
	March 31, 2016						December 31, 2015
	Principal Amount Outstanding		Carrying Amount		Estimated Fair Value		Principal Amount Outstanding		Carrying Amount		Estimated Fair Value
	(in thousands)
Brazil equipment financing	$	318,012	$	315,565	$	316,129	$	342,475	$	339,850	$	340,189
Brazil bank loans and other	257,062		263,525		264,553		234,320		240,922		229,366
	$	575,074	$	579,090	$	580,682	$	576,795	$	580,772	$	569,555

Bank loans and other consists primarily of loans with certain banks in Brazil. We estimated the fair value of these bank loans, as well as the fair value of our equipment financing facility in Brazil, utilizing inputs such as U.S. Treasury security yield curves, prices of comparable bonds, LIBOR, U.S. Treasury bond rates and credit spreads on comparable publicly traded bonds. We consider both Nextel Brazil's equipment financing facility and its bank loans and other to be Level 3 in the fair value hierarchy.

Derivative Instruments.

We occasionally enter into derivative transactions for risk management purposes. We have not and will not enter into any derivative transactions for speculative or profit generating purposes. We record all derivative instruments as either assets or liabilities on our condensed consolidated balance sheet at their fair value. As of March 31, 2016 and December 31, 2015, Nextel Brazil had an immaterial amount of derivative instruments that were classified as short-term investments on our condensed consolidated balance sheet. We consider this measurement to be Level 3 in the fair value hierarchy. Nextel Brazil entered into foreign currency option agreements to manage the foreign currency exposures associated with the forecasted purchase of handsets and other U.S. dollar-denominated payments. We do not apply hedge accounting to these derivative instruments. As a result, we have included all changes in the fair value of these instruments as a component of other (expense) income, net in our condensed consolidated statement of comprehensive income (loss). The gains and losses recognized in the three months ended March 31, 2016 were not material. For the three months ended March 31, 2015, Nextel Brazil recognized $9.9 million in unrealized gains resulting from the changes in the estimated fair value of these derivative instruments.

Other Financial Instruments.

The carrying values of cash and cash equivalents, accounts receivable and accounts payable contained in our condensed consolidated balance sheets approximate their fair values due to the short-term nature of these instruments.

Note 8. Commitments and Contingencies

Handset, Equipment and Other Commitments.

We are a party to purchase agreements with various suppliers under which we have committed to purchase handsets, equipment and network services that will be used or sold in the ordinary course of business. As of March 31, 2016, we are committed to purchase $171.6 million under a handset purchase agreement with one of our handset suppliers by the end of 2016. We do not expect that we will purchase all of the committed devices, but we have not recorded a liability for this contract because we do not believe it is probable that we will incur a loss under this handset purchase agreement.

Brazil Spectrum Commitment.

In December 2015, Nextel Brazil participated in a spectrum auction and was the successful bidder for 30 megahertz, or MHz, of spectrum in the 1.8 gigahertz, or GHz, band for 455.0 million Brazilian reais, or approximately $116.7 million based on foreign currency exchange rates at the time. Nextel Brazil received the license agreement on February 16, 2016 and is committed to pay 10% of the total acquisition price when this license agreement is signed.

Contingencies.

Nextel Brazil has received various assessment notices from state and federal Brazilian authorities asserting deficiencies in payments related primarily to value-added taxes, excise taxes on imported equipment and other non-income based taxes. Nextel Brazil has filed various administrative and legal petitions disputing these assessments. In some cases, Nextel Brazil has received favorable decisions, which are currently being appealed by the respective governmental authority. In other cases, Nextel Brazil's petitions have been denied, and Nextel Brazil is currently appealing those decisions. Nextel Brazil also had contingencies related to certain regulatory, civil and labor-related matters as of March 31, 2016 and December 31, 2015.

As of March 31, 2016 and December 31, 2015, Nextel Brazil had accrued liabilities of $58.5 million and $57.7 million, respectively, related to contingencies, of which $4.6 million and $5.4 million related to unasserted claims, respectively. We currently estimate the reasonably possible losses related to matters for which Nextel Brazil has not accrued liabilities, as they are not deemed probable, to be approximately $305.0 million as of March 31, 2016. We continue to evaluate the likelihood of probable and reasonably possible losses, if any, related to all known contingencies. As a result, future increases or decreases to our accrued liabilities may be necessary and will be recorded in the period when such amounts are determined to be probable and reasonably estimable.

In addition, as of March 31, 2016, we estimated the reasonably possible losses related to potential indemnification claims in connection with the sales of Nextel Mexico and Nextel Peru for which we have not accrued liabilities, as they are not deemed probable, to be approximately $41.0 million.

Legal Proceedings.

We are subject to claims and legal actions that may arise in the ordinary course of business. We do not believe that any of these pending claims or legal actions will have a material effect on our business, financial condition, results of operations or cash flows.

Note 9. Income Taxes

The realization of deferred tax assets is dependent on the generation of future taxable income sufficient to realize our tax loss carryforwards and other tax deductions. Valuation allowances are required to be recognized on deferred tax assets unless it is determined that it is “more-likely-than-not” that the asset will be realized. In 2015, we recorded full valuation allowances on the deferred tax assets of our foreign operating companies, our U.S. parent company and subsidiaries and our foreign holding companies due to substantial negative evidence such as the recent history of cumulative losses and the projected losses for 2016 and subsequent years. We maintained this same valuation allowance position through the first three months of 2016.

Note 10. Segment Reporting

We have determined our reportable segment based on our method of internal reporting, which disaggregates our business by geographic location. We evaluate performance and provide resources to it based on operating income before depreciation, amortization and impairment, restructuring and other charges, which we refer to as segment earnings. Nextel Brazil is our only reportable operating segment.

Introduction

The following is a discussion and analysis of:

• our consolidated financial condition as of March 31, 2016 and December 31, 2015 and our consolidated results of operations for the three-month periods ended March 31, 2016 and 2015; and

• significant factors that we believe could affect our prospective financial condition and results of operations.

You should read this discussion in conjunction with our 2015 annual report on Form 10-K, including, but not limited to, the discussion regarding our critical accounting policies and estimates, as described below. Historical results may not indicate future performance. See "Forward-Looking and Cautionary Statements," "Item 1A. — Risk Factors" in our 2015 annual report on Form 10-K for risks and uncertainties that may impact our future performance. We refer to our remaining operating company as Nextel Brazil.

Nextel Brazil Business Overview

We provide wireless communication services under the Nextel^TM brand in Brazil with our principal operations located in major urban and suburban centers with high population densities and related transportation corridors of that country where we believe there is a concentration of Brazil's business users and economic activity, including primarily Rio de Janeiro and São Paulo.

In the second half of 2013, Nextel Brazil commercially launched services on its wideband code division multiple access, or WCDMA, network in São Paulo, Rio de Janeiro and surrounding areas and extended those services to other areas in Brazil by expanding the coverage of its network and utilizing roaming services and network sharing arrangements pursuant to agreements that it reached with another network operator in Brazil. Nextel Brazil currently offers services supported by its WCDMA network in approximately 260 cities in Brazil. Our WCDMA network enables us to offer a wide range of products and services supported by that technology, including data services provided at substantially higher speeds than can be delivered on our legacy integrated digital enhanced network, or iDEN.

Prior to the deployment of our WCDMA network, our services were primarily targeted to meet the needs of business customers. With the deployment of our WCDMA network in Brazil, our target market has shifted to individual consumers who use our services to meet both professional and personal needs. Our target subscribers generally exhibit above average usage, revenue and loyalty characteristics. We believe our target market is attracted to the services and pricing plans we offer, as well as the quality of and data speeds provided by our WCDMA network.

We also offer long-term evolution, or LTE, services in Rio de Janeiro and continue to provide services on our legacy iDEN network throughout various regions in Brazil. Our transition to standards-based technologies such as WCDMA also gives us more flexibility to offer customers the option of purchasing services by acquiring the subscriber identity module, or SIM, cards from us separately, and by providing the customer with the option to use the SIM cards in one or more devices that they acquire from us or from other sources.

The services we currently offer include:

• mobile telephone voice service;

• wireless data services, including text messaging services, mobile internet services and email services;

• push-to-talk services, including Direct Connect^®, Prip and International Direct Connect^® services, which allow subscribers to talk to each other instantly;

• other value-added services, including location-based services, which include the use of Global Positioning System, or GPS, technologies; digital media services; and a wide ranging set of applications available via our content management system, as well as the Android^TM open application market;

• business solutions, such as security, work force management, logistics support and other applications that help our business subscribers improve their productivity; and

• voice and data roaming services outside of our coverage areas.

Our goal is to generate higher revenues and increase our subscriber base by providing differentiated wireless communications services that are valued by our existing and potential customers, while managing our capital and operating expenditures in the near term and improving our profitability and cash flow over the long term. Our strategy for achieving this goal is based on several core principles, including:

20

• aligning our costs with our current business through continuous evaluation and streamlining of all capital and operating expenditures;

• focusing on higher value customer segments that generate higher average revenue per user, or ARPU, and lower customer turnover;

• utilizing the most profitable sales channels;

• offering a superior customer experience, including a reliable and high quality wireless network; and

• building on the strength of the unique positioning of the Nextel brand.

To support our business plan, we have made significant capital and other investments as we deployed our WCDMA network and LTE upgrade. These investments have increased our costs and negatively impacted our profitability and are expected to continue to have that impact as we incur the fixed costs associated with our network while building the subscriber base it serves. However, we believe our investments have enhanced, and will continue to enhance, the competitiveness of our service offerings while continuing to support the differentiated services and superior customer service that have historically been significant factors supporting our business.

We have implemented and will continue to implement changes in our business to better align our organization and costs with our operational and financial results and goals, as well as with the trends in our business. These changes have included changes to our leadership team in Brazil, significant reductions in our headquarters staff through the reorganization of the roles and responsibilities of both our Brazil and corporate teams, and headcount reductions in Brazil, all of which are designed to reduce costs while maintaining the support necessary to meet our customers' needs.

As a result of the sale of Nextel Argentina in September 2015 and Nextel Mexico in April 2015, both of which followed the sale of Nextel Chile in August 2014 and Nextel Peru in August 2013, we plan to allocate almost all of our financial and other resources to our operations in Brazil going forward.

Critical Accounting Policies and Estimates

The preparation of our financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates, assumptions and judgments that affect the reported amounts of assets and liabilities, revenues and expenses and related disclosures of contingent assets and liabilities in the condensed consolidated financial statements and accompanying notes. Although we believe that our estimates, assumptions and judgments are reasonable, they are based on presently available information. Due to the inherent uncertainty involved in making those estimates, actual results reported in future periods could differ from those estimates.

As described in more detail in our 2015 annual report on Form 10-K under “Management's Discussion and Analysis of Financial Condition and Results of Operations,” we consider the following accounting policies to be the most important to our financial position and results of operations or policies that require us to exercise significant judgment and/or estimates:

• revenue recognition;

• allowance for doubtful accounts;

• depreciation of property, plant and equipment;

• amortization of intangible assets;

• valuation of long-lived assets;

• foreign currency;

• loss contingencies; and

• income taxes.

There have been no material changes to our critical accounting policies and estimates during the three months ended March 31, 2016 compared to those discussed under “Management's Discussion and Analysis of Financial Condition and Results of Operations” in our 2015 annual report on Form 10-K.

Results of Operations

As a result of the application of fresh start accounting, the Successor Company's financial results for the three months ended March 31, 2016 are prepared under a new basis of accounting and are not directly comparable to the Predecessor Company's financial results for the three months ended March 31, 2015.

In accordance with accounting principles generally accepted in the U.S., we translated the results of operations of our Brazilian operating segment into U.S. dollars using the average foreign currency exchange rates for the applicable period. The following table presents the average foreign currency exchange rates we used to translate Nextel Brazil's results of operations, as well as changes from the average foreign currency exchange rates utilized in the prior period.

	Successor Company	Predecessor Company	Actual Percent Change From Prior Year
	Three Months Ended March 31,
	2016	2015
Brazilian real	3.91	2.86	(37	)%

During 2015, foreign currency exchange rates in Brazil generally depreciated in value relative to the U.S. dollar. During the first quarter of 2016, the foreign currency exchange rates experienced a slight appreciation compared to the rate in effect at the end of the prior year. The following table presents the foreign currency exchange rates in effect at the end of each of the quarters in 2015, as well as at the end of the first quarter of 2016.

	Predecessor Company		Successor Company
	2015				2016
	March	June	September	December	March
Brazilian real	3.21	3.10	3.97	3.90	3.56

To provide better insight into Nextel Brazil's results, we present the year-over-year percentage change in each of the line items presented on a consolidated basis and for Nextel Brazil on a constant currency basis in the "Constant Currency Change from Previous Year" columns in the tables below. The comparison of results for these line items on a constant currency basis shows the impact of changes in foreign currency exchange rates (i) by adjusting the relevant measures for the three months ended March 31, 2015 to amounts that would have resulted if the average foreign currency exchange rates for the three months ended March 31, 2015 were the same as the average foreign currency exchange rates that were in effect for the three months ended March 31, 2016; and (ii) by comparing the constant currency financial measures for the three months ended March 31, 2015 to the actual financial measures for the three months ended March 31, 2016. This constant currency comparison applies consistent exchange rates to the operating revenues earned in Brazilian reais and to the other components of segment earnings for the three months ended March 31, 2015. The constant currency information reflected in the tables below is not a measurement under accounting principles generally accepted in the U.S. and should be considered in addition to, but not as a substitute for, the information contained in our results of operations.

We define segment earnings (losses) as operating loss before depreciation, amortization and impairment, restructuring and other charges. Consolidated segment losses decreased $10.3 million, or 56%, for the three months ended March 31, 2016 compared to the same period in 2015 and include the results of operations of our Brazil segment and our corporate operations, both of which are discussed individually below.

1. Impairment, restructuring and other charges

Consolidated impairment, restructuring and other charges recognized in the three months ended March 31, 2016 primarily consisted of $3.2 million in restructuring charges related to future lease costs for certain transmitter and receiver sites that are no longer required in Nextel Brazil's business and certain office closures, as well as $1.3 million in severance and other related costs at the corporate level as a result of the separation of employees in an effort to streamline our organizational structure and reduce general and administrative expenses.

Consolidated impairment, restructuring and other charges recognized in the three months ended March 31, 2015 primarily represented $3.7 million of non-cash asset asset impairment charges related to the shutdown or abandonment of transmitter and receiver sites in Brazil and $2.0 million of severance costs incurred in Brazil resulting from the separation of employees in an effort to streamline our organizational structure and reduce general and administrative expenses.

2. Depreciation and amortization

The $40.1 million, or 50%, decrease in consolidated depreciation and amortization on a reported basis, and the 32% decrease on a constant currency basis, for the three month ended March 31, 2016 compared to the same period in 2015 was principally the result of a decrease in the value of Nextel Brazil's property, plant and equipment resulting from the implementation of fresh start accounting.

3. Interest expense, net

Consolidated net interest expense decreased $10.1 million, or 28%, on a reported basis, for the three months ended March 31, 2016 compared to the same period in 2015 primarily as a result of the depreciation in the value of the Brazilian real relative

23

to the U.S. dollar. On a constant currency basis, consolidated net interest expense increased 7% over the same period primarily as the result of an increase in interest rates on Nextel Brazil's local loans.

4. Foreign currency transaction gains (losses), net

Consolidated foreign currency transaction gains of $39.6 million during the three months ended March 31, 2016 were primarily the result of the impact of the appreciation in the value of the Brazilian real relative to the U.S. dollar during the period on Nextel Brazil's U.S. dollar-denominated net liabilities.

Consolidated foreign currency transaction losses of $78.5 million for the three months ended March 31, 2015 were largely the result of the impact of the depreciation in the value of the Brazilian real relative to the U.S. dollar during the period on Nextel Brazil's U.S. dollar-denominated liabilities.

5. Other (expense) income, net

Consolidated net other expense of $2.5 million for the three months ended March 31, 2016 primarily related to withholding taxes.

Consolidated net other income of $9.2 million for the three months ended March 31, 2015 largely related to gains on the exercise of foreign currency options in Brazil that are used to manage the foreign currency exposure associated with the forecasted purchase of handsets and other U.S. dollar-denominated payments.

6. Reorganization items

Reorganization items for the three months ended March 31, 2016 and 2015 consisted of professional fees and other costs related to our Chapter 11 filing.

We use the term "subscriber unit," which we also refer to as a subscriber, to represent an active subscriber identity module, or SIM, card, which is the level at which we track subscribers. The table below provides an overview of Nextel Brazil's subscriber units in commercial service on both its iDEN and WCDMA networks, as well as Nextel Brazil's customer turnover rates for each of the quarters in 2015 and for the first quarter of 2016. We calculate customer turnover by dividing subscriber deactivations for the period by the average number of subscriber units during that period.

(1) Total net subscriber losses and customer turnover for each quarter presented were revised to include adjustments to reduce Nextel Brazil's subscriber base by approximately 45,400 subscribers (15,700 WCDMA subscribers and 29,700 iDEN subscribers) that were not properly deactivated in periods prior to the first quarter of 2016.

25

(2) For the three months ended September 30, 2015, migrations from iDEN to WCDMA included approximately 31,000 migrations which were not properly reported in prior quarters. This change in migrations did not impact total subscriber units at the end of any period presented.

The following table represents Nextel Brazil's average monthly revenue per subscriber, or ARPU, for subscribers on both its iDEN and WCDMA networks for each of the quarters in 2015, as well as for the first quarter of 2016, in both U.S. dollars (US$) and in Brazilian reais (BR). We calculate service ARPU by dividing service revenues per period by the weighted average number of subscriber units in commercial service during that period.

	Predecessor Company		Successor Company
	Three Months Ended		Three Months Ended
	March 31, 2015	June 30, 2015	September 30, 2015	December 31, 2015	March 31, 2016

(1) Total service ARPU in both U.S. dollars and Brazilian reais for each quarter presented includes the impact of adjustments to reduce Nextel Brazil's subscriber base for subscribers that were not properly deactivated in prior periods.

The average value of the Brazilian real depreciated relative to the U.S. dollar during the first quarter of 2016 by 37% compared to the average value that prevailed during the first quarter of 2015. As a result, the components of Nextel Brazil's results of operations for the three months ended March 31, 2016, after translation into U.S. dollars, reflect lower revenues and expenses in U.S. dollars than would have occurred if the Brazilian real had not depreciated relative to the U.S. dollar. If the value of the Brazilian real remains at current levels or depreciates further relative to the U.S. dollar, Nextel Brazil's future reported results of operations will be adversely affected.

The economic environment in Brazil continues to reflect a significant downturn from prior years with low consumer confidence, negative real wage growth, a net loss of jobs and higher unemployment. Consumers in Brazil are also being impacted by rising costs of food and other essentials, with the inflation of food costs significantly exceeding both inflation levels experienced in prior years and the consumer price index. These conditions and trends have resulted in a decline in the amount of consumer disposable income that is available to purchase telecommunications services and have had an adverse impact on our ability to attract and retain subscribers and on our collection rates. We expect that the current economic conditions and weak foreign currency exchange rates will continue to have a negative impact on Nextel Brazil's reported results of operations through at least the end of 2016.

Nextel Brazil began offering a full range of voice and data services on its WCDMA network in late 2013 and experienced subscriber growth on its WCDMA network and an increase in its WCDMA service ARPU in Brazilian reais through the end of 2014. Although Nextel Brazil's WCDMA subscriber units increased from 337.9 thousand subscribers as of January 1, 2014 to 2.7 million subscribers as of March 31, 2016, Nextel Brazil's WCDMA service ARPU in Brazilian reais has decreased slightly over the course of the last year, and its WCDMA customer turnover increased significantly in the first quarter of 2016, as a result of more intense competition in the wireless market and the economic factors discussed above. In addition, the competitive environment in the Brazilian wireless industry was characterized by aggressive pricing and service offerings throughout 2015 and into the first quarter of 2016. In the second quarter of 2015, Nextel Brazil implemented several new rate plans and promotions to improve the attractiveness of its service offerings, expand targeted customer segments and provide economic incentives to attract customers. Specifically, in June 2015, Nextel Brazil began offering new simplified rate plans that further incentivize subscribers to utilize their existing handsets when purchasing Nextel Brazil's services, which generally result in similar or higher service ARPU levels. In addition, during the fourth quarter of 2015, Nextel Brazil launched promotions to increase prices on certain rate plans, which resulted in higher service ARPU levels for new WCDMA customers during the first quarter of 2016 compared to the levels experienced during the fourth quarter of 2015.

Nextel Brazil continues to offer services on its iDEN network, which does not support data services that are competitive with the higher speed data services offered by its competitors or available on its WCDMA network. As a result, Nextel Brazil has had to offer iDEN service plans with lower average revenues per subscriber to retain and attract high value subscribers on its iDEN network and offer incentives to transition those subscribers to services on its WCDMA network. Despite these efforts, Nextel

26

Brazil has experienced net subscriber losses and declines in its average revenue per subscriber on its iDEN network, and we expect that these trends will continue.

As a result of these factors, Nextel Brazil's average revenue per subscriber during the three months ended March 31, 2016 was lower than its average revenue per subscriber during the same period in 2015, which, in combination with the impact of weaker foreign currency exchange rates, caused the $120.1 million, or 35%, decline in Nextel Brazil's service and other revenues over the same period. On a constant currency basis, Nextel Brazil's service and other revenues decreased 11%, and its average revenue per subscriber decreased 6% in the three months ended March 31, 2016 compared to the same period in 2015.

Nextel Brazil had a segment earnings margin of 2% for the three months ended March 31, 2016. Nextel Brazil recognized segment earnings of $3.8 million during the three months ended March 31, 2016 compared to segment earnings of $3.5 million during the same period in 2015 as a result of the following:

1. Service and other revenues

The $120.1 million, or 35%, decrease in service and other revenues on a reported basis in the three months ended March 31, 2016 compared to the same period in 2015 is primarily the result of the impact of weaker foreign currency exchange rates on our reported results and the decline in service ARPU discussed above. On a constant currency basis, Nextel Brazil's service and other revenues decreased 11% in the first quarter of 2016 compared to the same period in 2015.

Nextel Brazil's WCDMA subscriber base grew from 2.0 million subscribers as of the end of the first quarter of 2015 to 2.7 million subscribers as of the end of the first quarter of 2016. Nextel Brazil has continued to strategically facilitate the migration of iDEN subscribers to its WCDMA network, which resulted in 41.7 thousand migrations during the three months ended March 31, 2016. As a result of the overall growth in its WCDMA subscriber base, Nextel Brazil's WCDMA-based service and other revenues increased $0.5 million from the three months ended March 31, 2015 to the same period in 2016, or 37% on a constant currency basis. This increase was offset by a $120.6 million, or 61%, decrease in Nextel Brazil's iDEN-based service and other revenues from the three months ended March 31, 2015 to the same period in 2016, or 47% on a constant currency basis, driven by a decrease in Nextel Brazil's iDEN subscriber base from 2.4 million subscribers as of the end of the first quarter of 2015 to 1.3 million subscribers as of the end of the first quarter of 2016 and a decline in its iDEN-based average revenue per subscriber from $22 for the first quarter of 2015 to $15 for the first quarter of 2016.

2. Handset and accessory net subsidy

The $27.8 million, or 84%, decrease in handset and accessory net subsidy on a reported basis from the first quarter of 2015 to the same period in 2016 is largely related to an increased emphasis on new service plans under which services are provided to new subscribers using their existing handsets, as well as lower subsidies per handset. As a result of the new service plans, 85% of Nextel Brazil's new WCDMA subscribers during the first quarter of 2016 represented customers who utilized their existing handsets compared to 48% of new WCDMA subscribers utilizing their existing handsets during the first quarter of 2015. On a constant currency basis, Nextel Brazil's handset and accessory net subsidy decreased 78% for the three months ended March 31, 2016 compared to the same period in 2015.

3. Cost of service

The $40.1 million, or 31%, decrease in cost of service on a reported basis from the first quarter of 2015 to the same period in 2016 is primarily caused by the impact of weaker foreign currency exchange rates described above. On a constant currency basis, Nextel Brazil's cost of service decreased 5% for the three months ended March 31, 2016 to the same period in 2015 primarily as the result of a decrease in interconnect costs related to lower mobile termination rates. In addition, on a constant currency basis, Nextel Brazil recognized significant cost savings in the first quarter of 2016 compared to the same period in 2015 as a result of insourcing certain engineering functions that were previously performed by third party service providers. Also, with the continuing decline in the number of iDEN subscribers in Nextel Brazil's subscriber base, Nextel Brazil's service and repair costs related to its iDEN handset maintenance program continued to decrease. These decreases were partially offset by an increase in costs related to Nextel Brazil's nationwide roaming arrangement, as well as an increase in direct switch and transmitter and receiver site costs on a local currency basis due to higher site rent expense resulting from inflation.

In 2012, Brazil's telecommunications regulatory agency approved regulations to implement a transition to a cost-based model for determining mobile termination rates. Under the current regulations, the mobile termination rates are being gradually reduced over a transition period ending in 2019, when cost-based rates will take effect. The transition rules also provide for a partial "bill and keep" settlement process that applies to the settlement of mobile termination charges between smaller operators like Nextel Brazil and its larger competitors (who are considered to hold significant market power under the Brazilian regulations), which

27

further reduces mobile termination charges for smaller operators. The lower costs resulting from this partial bill and keep settlement process, which is similar to the settlement process that has historically applied to termination charges relating to our iDEN services, decline as mobile termination rates are reduced during the transition period, with the bill and keep settlement process terminating when cost-based rates are implemented.

4. Selling and marketing expenses

The $26.8 million, or 55%, decrease in selling and marketing expenses on a reported basis during the first quarter of 2016 compared to the same period in 2015 is partially due to the impact of weaker foreign currency exchange rates described above. On a constant currency basis, Nextel Brazil's selling and marketing expenses decreased 38% in the three months ended March 31, 2016 compared to the same period in 2015 as the result of a reduction in sales and marketing personnel, lower advertising and media expenses resulting from cost reductions and retail store closures.

5. General and administrative expenses

The $25.5 million, or 20%, decrease in general and administrative expenses on a reported basis for the first quarter of 2016 compared to the same period 2015 is due to the impact of weaker foreign currency exchange rates described above. On a constant currency basis, Nextel Brazil's general and administrative expenses increased 9% over the same period primarily as a result of an increase in bad debt expense resulting from lower collections and higher consulting expenses.

Segment losses decreased $11.0 million, or 48% in the three months ended March 31, 2016 compared to the three months ended March 31, 2015 primarily due to a reduction in payroll costs resulting from fewer general and administrative personnel following reductions in force that we implemented in 2015, lower consulting expenses and lower information technology costs.

Liquidity and Capital Resources

As of March 31, 2016, we had a working capital deficit of $234.0 million compared to a working capital deficit of $177.4 million as of December 31, 2015. As of March 31, 2016, our working capital included $332.7 million in cash and cash equivalents, of which $1.3 million was held by Nextel Brazil in Brazilian reais, and $35.0 million in short-term investments, which was also held in Brazilian reais. In addition, as of March 31, 2016, we had $160.7 million of cash collateral securing certain performance bonds relating to our obligations to deploy spectrum in Brazil, of which we recorded $99.5 million as a component of other assets and the remaining $61.2 million of which we recorded as a component of prepaid expenses and other in our condensed consolidated balance sheet. As of March 31, 2016, we also had $227.0 million in cash held in escrow in connection with the sales of Nextel Argentina, Nextel Mexico and Nextel Peru and $67.0 million in judicial deposits in Brazil, all of which we classified as restricted cash.

A substantial portion of our U.S. dollar-denominated cash, cash equivalents and short-term investments is held in bank deposits and U.S. treasury securities, and our cash, cash equivalents and short-term investments held in Brazilian reais are typically maintained in a combination of money market funds, highly liquid overnight securities and fixed income investments. The values of our cash, cash equivalents and short-term investments that are held in Brazilian reais will fluctuate in U.S. dollars based on changes in the exchange rate of the Brazilian real relative to the U.S. dollar. Our current sources of funding include our cash, cash equivalent and short-term investment balances.

The following is a discussion of the primary sources and uses of cash in our operating, investing and financing activities.

We used $18.2 million of cash in our operating activities during the three months ended March 31, 2016, a $152.7 million decrease from the three months ended March 31, 2015, primarily due to decreased operating losses.

Our investing activities provided us with $33.7 million of cash during the three months ended March 31, 2016, primarily due to $54.6 million in net proceeds received from maturities of our short-term investments in Brazil and at the corporate level, partially offset by $8.4 million in cash capital expenditures. We used $116.9 million of cash in our investing activities during the three months ended March 31, 2015, primarily due to $51.3 million in cash used by our discontinued operations, $45.8 million in cash capital expenditures and $9.8 million in net purchases of short-term investments in Brazil.

We used $24.7 million of cash in our financing activities during the three months ended March 31, 2016, mostly due to the $24.4 million semi-annual principal repayment under Nextel Brazil's equipment financing facility. Our financing activities provided us with $335.9 million of cash during the first quarter of 2015, largely due to $339.4 million in net proceeds we received from the debtor-in-possession loan agreement we entered into in March 2015.

Future Capital Needs and Resources

Over the course of the last several years, our results of operations, including our operating revenues and operating cash flows, have been negatively affected by a number of factors, including significant deterioration in economic conditions in Brazil, increased competitive pressure, the overall depreciation of the value of the Brazilian real relative to the U.S. dollar and the impact of previous delays in the deployment and launch of services on our WCDMA network in Brazil. These and other factors resulted in a reduction in our subscriber growth and revenues at a time when our costs reflected the operation of both of our networks and had a significant negative impact on our results and our ability to grow our revenue base to a level sufficient to reach the scale required to generate positive operating income.

As a result, in 2014, we concluded that we were not able to maintain sufficient liquidity to support our business plan and repay our debts when they come due, including $4.35 billion of senior notes issued by NII International Telecom, S.C.A., or NIIT, and NII Capital Corp. On September 15, 2014, we and eight of our U.S. and Luxembourg-domiciled subsidiaries, filed voluntary petitions seeking relief under Chapter 11 of Title 11 of the United States Bankruptcy Code, which we refer to as Chapter 11, in the United States Bankruptcy Court for the Southern District of New York, which we refer to as the Bankruptcy Court. Subsequent to September 15, 2014, five additional subsidiaries filed voluntary petitions seeking relief under Chapter 11 in the Bankruptcy Court. On June 26, 2015, we and the other Debtors emerged from the Chapter 11 proceedings. Our operating subsidiaries in Brazil, Mexico and Argentina were not debtors in the Chapter 11 cases. See Note 2 to our condensed consolidated financial statements for more information regarding the impact of the implementation of the Plan of Reorganization.

We will use the remainder of the proceeds received from the sales of Nextel Argentina in September 2015 and Nextel Mexico in April 2015, both of which followed the sales of Nextel Chile in August 2014 and Nextel Peru in August 2013, to fund our operations in Brazil.

Capital Resources.  Our ongoing capital resources depend on a variety of factors, including our existing cash, cash equivalents and investment balances, cash flows generated by our operating activities, cash that we recover from the amounts held in escrow

29

to secure our indemnification obligations in connection with the sales of Nextel Argentina, Nextel Mexico and Nextel Peru, the return of cash pledged as collateral to secure certain performance bonds relating to our obligations to deploy our spectrum in Brazil, external financial sources, other financing arrangements and the availability of cash proceeds from the sale of assets.

Our ability to generate sufficient net cash from our operating activities in the future is dependent upon, among other things:

• the amount of revenue we are able to generate and collect from our subscribers, including our ability to increase the size of our subscriber base;

• the amount of operating expenses required to provide our services;

• the cost of acquiring and retaining customers, including the subsidies we incur to provide handsets to both our new and existing subscribers; and

• changes in foreign currency exchange rates.

Due to the impact of our recent and projected results of operations and other factors, we expect our access to the capital markets in the near term may be limited. See "— Future Outlook and Liquidity Plans"for more information.

Capital Needs and Contractual Obligations.  We currently anticipate that our future capital needs will principally consist of funds required for:

• operating expenses and capital expenditures relating to our existing network and the planned deployment of LTE in other commercial areas in Brazil;

• payments in connection with spectrum purchases, including ongoing spectrum license fees;

• debt service requirements;

• obligations relating to our tower financing arrangements and capital lease obligations;

• cash taxes; and

• other general corporate expenditures.

During the three months ended March 31, 2016, there were no material changes to our total contractual obligations as described in our annual report on Form 10-K for the year ended December 31, 2015.

Capital Expenditures.  Our capital expenditures, including capitalized interest, were $7.6 million and $14.9 million for the three months ended March 31, 2016 and 2015, respectively. We have reduced our investments in capital expenditures, including making substantial reductions to our investments in network development and deployment. We expect these efforts to conserve our cash resources to continue.

Our capital spending and related expenses are expected to be driven by several factors, including:

• the amount we spend to enhance our WCDMA network in Brazil and deploy our planned LTE upgrade;

• the extent to which we expand the coverage of our network in new or existing market areas;

• the number of additional transmitter and receiver sites we build in order to increase system capacity, maintain system quality and meet our regulatory requirements, as well as the costs associated with the installation of network infrastructure and switching equipment; and

• the costs we incur in connection with non-network related information technology projects.

Our future capital expenditures may also be affected by future technology improvements, technology choices and our available capital.

Maintenance Covenants Under Financing Agreements. As of March 31, 2016, we had $256.5 million principal amount outstanding under Nextel Brazil's local bank loans. As discussed in more detail in Note 1 and Note 6 to our condensed consolidated financial statements, we are required to meet a net debt financial covenant included in the local bank loan agreements that will apply semiannually beginning on June 30, 2016. Based on our current business plan, we believe that it is unlikely that we will satisfy the applicable financial covenant at the June 30, 2016 measurement date. We will need to refinance or negotiate amendments to these financing arrangements or secure waivers from the lenders in order to avoid a potential default under the loan agreements. If a default occurs, the lenders could require us to repay the amounts outstanding under these arrangements. As a result of this

30

uncertainty, we have continued to classify the amounts outstanding under Nextel Brazil's local bank loans as current liabilities in our condensed consolidated balance sheet as of March 31, 2016.

In December 2014, Nextel Brazil and the lender under the equipment financing facility agreed to amend this facility to remove all financial covenants beginning with the December 31, 2014 measurement date through the June 30, 2017 measurement date so that the first measurement date under the amended facility will be December 31, 2017. As of March 31, 2016, we had $318.0 million in principal amount outstanding under Nextel Brazil's equipment financing facility. Because of the uncertainty regarding our ability to meet the financial covenant contained in Nextel Brazil's local bank loans discussed above and certain cross-default provisions that are included in the loan agreement under Nextel Brazil's equipment financing facility, we have continued to classify the amount outstanding under this facility as a current liability in our condensed consolidated balance sheet as of March 31, 2016.

Future Outlook and Liquidity Plans.  In connection with our emergence from Chapter 11, we made a number of changes within our senior management team and modified our business plan to reflect our available cash resources and the impact of the current and expected economic and competitive conditions in Brazil on both our subscriber growth and revenues, and to align our costs with this revised outlook. Our current sources of funding are our cash and investments on hand; the ultimate amount recovered from cash currently held in escrow to secure our indemnification obligations in connection with the sales of Nextel Argentina, Nextel Mexico and Nextel Peru; the return of cash pledged as collateral to secure certain performance bonds relating to our obligations to deploy our spectrum in Brazil; and funds generated from our operations. As of March 31, 2016, assuming the availability of these funding sources, and if we are successful in making the necessary changes to our business that are factored into our revised business plan, we expect to have sufficient liquidity to continue to fund our business for about two years.

If we do not meet the results in our revised business plan, or if anticipated funding sources are not available to us, including the release of cash held in escrow, it is likely that we would need to obtain additional funding in the next twelve to fifteen months. We believe that the uncertainties relating to our business, together with the restrictions in our current financing arrangements and general conditions in the financial and credit markets, may make it challenging for us to obtain additional funding. In addition, the cost of any additional funding that we may require, if available, could be both significant and higher than the cost of our existing financing arrangements. Our inability to obtain suitable financing if and when it is required for these or other reasons could, among other things, negatively impact our results of operations and liquidity.

In making the assessment of our funding needs and the adequacy of our current sources of funding, we have considered:

• cash and cash equivalents on hand and short-term investments available to fund our operations;

• restricted cash currently held in escrow to secure our indemnification obligations in connection with the sales of Nextel Argentina, Nextel Mexico and Nextel Peru;

• the future return of cash pledged as collateral to secure certain performance bonds relating to our obligations to deploy our spectrum in Brazil;

• cash proceeds from sales of assets, including the potential sale of additional transmitter and receiver sites in Brazil;

• expected cash flows from our operation in Brazil;

• the cost of purchasing spectrum, the financing available to fund such purchases, and timing of spectrum payments, including ongoing fees for spectrum use;

• the anticipated level of capital expenditures required to meet both minimum build-out requirements and our planned deployment of the WCDMA network in Brazil, as well as our planned deployment of LTE in other commercial areas in Brazil;

• our scheduled debt service obligations;

• our other contractual obligations; and

• cash income and other taxes.

In addition to the factors described above, the anticipated cash needs of our business, as well as the conclusions presented herein regarding our liquidity needs, could change significantly:

• based on the continued development of our business plans and strategy;

31

• if we decide to expand into new markets or expand our geographic coverage or network capacity in our existing markets beyond our current plans, as a result of the construction of additional portions of our network or the acquisition of competitors or others;

• if currency values in Brazil depreciate or appreciate relative to the U.S. dollar in a manner that is more significant than we currently expect and assume as part of our plans;

• if economic conditions in Brazil do not improve or worsen;

• if competitive practices in the mobile wireless telecommunications industry in Brazil change materially from those currently prevailing or from those now anticipated; or

• if other presently unexpected circumstances arise that have a material effect on the cash flow or profitability of our business.

Effect of New Accounting Standards

In March 2016, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update, or ASU, No. 2016-09, “Improvements to Employee Share-Based Payment Accounting,” which includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. We early adopted this ASU in the first quarter of 2016. Under the new guidance, we made an accounting policy election to recognize the impact of forfeited awards on compensation expense when they occur, rather than initially reducing expense for an estimate of future forfeitures. This policy was applied using a modified retrospective approach and resulted in an immaterial cumulative effect adjustment to retained earnings.

Forward-Looking and Cautionary Statements

This quarterly report on Form 10-Q may contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, as amended. Statements regarding expectations, including forecasts regarding operating results, performance assumptions and estimates relating to capital requirements, as well as other statements that are not historical facts, are forward-looking statements. These forward-looking statements are generally identified by such words or phrases as “we expect,” “we believe,” “would be,” “will allow,” “expects to,” “will continue,” “is anticipated,” “estimate,” “project” or similar expressions. These forward-looking statements involve risk and uncertainty, and a variety of facts could cause our actual results and experience to differ materially from the anticipated results or other expectations expressed in these forward-looking statements. We do not have a policy of updating or revising forward-looking statements except as otherwise required by law.

While we provide forward-looking statements to assist in the understanding of our anticipated future financial performance, we caution readers not to place undue reliance on any forward-looking statements, which speak only as of the date that we make them. Forward-looking statements are based on current expectations and assumptions that are subject to significant risks and uncertainties that could cause actual results to differ materially from those in the forward-looking statements. Except as otherwise required by law, we undertake no obligation to publicly release any updates to forward-looking statements to reflect events after the date of this quarterly report on Form 10-Q, including unforeseen events.

Our ability to predict results or the actual effect of future plans or strategies is inherently uncertain. Factors that could have a material adverse effect on our operations and results of our business include, but are not limited to:

• our ability to attract and retain customers;

• our ability to satisfy the requirements of our debt obligations;

• our ability to access sufficient debt or equity capital to meet any future operating and financial needs;

• our ability to meet established operating goals and generate cash flow;

• the availability of other funding sources, including the proceeds from the sales of Nextel Argentina, Nextel Mexico and Nextel Peru held in escrow and proceeds derived from other asset sales;

• general economic conditions in Brazil and in the market segments that we are targeting for our services;

• the political and social conditions in Brazil, including political instability, which may affect Brazil's economy and the regulatory scheme there;

32

• the impact of foreign currency exchange rate volatility in the local currency in Brazil when compared to the U.S. dollar and the impact of related currency depreciation in Brazil;

• our having reasonable access to and the successful performance of the technology being deployed in our service areas, and improvements thereon, including technology deployed in connection with the introduction of digital two-way mobile data or internet connectivity services in our markets;

• the availability of adequate quantities of system infrastructure and subscriber equipment and components at reasonable pricing to meet our service deployment and marketing plans and customer demand;

• risks related to the operation and expansion of our WCDMA network in Brazil, including the potential need for additional funding to support enhanced coverage and capacity, and the risk that new services supported by the WCDMA network will not attract enough subscribers to support the related costs of deploying or operating the network;

• our ability to successfully scale our billing, collection, customer care and similar back-office operations to keep pace with customer growth as necessary, increased system usage rates and growth or to successfully deploy new systems that support those functions;

• future legislation or regulatory actions relating to our services, other wireless communications services or telecommunications generally and the costs and/or potential customer impacts of compliance with regulatory mandates;

• the ability to achieve and maintain market penetration and average subscriber revenue levels sufficient to provide financial viability to our network business;

• the quality and price of similar or comparable wireless communications services offered or to be offered by our competitors, including providers of cellular services and personal communications services;

• market acceptance of our new service offerings;

• our ability to successfully manage and support our legacy iDEN network in Brazil;

• equipment failure, natural disasters, terrorist acts or other breaches of network or information technology security; and

• other risks and uncertainties described in Part I, Item 1A. "Risk Factors," in our annual report on Form 10-K for the year ended December 31, 2015 and, from time to time, in our other reports filed with the SEC.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

During the three months ended March 31, 2016, there were no material changes to our market risk policies or our market risk sensitive instruments and positions as described in our annual report on Form 10-K for the year ended December 31, 2015.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods required by the Securities and Exchange Commission, or the SEC, and that such information is accumulated and communicated to the Company's management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

As of March 31, 2016, an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures was carried out under the supervision and with the participation of our management teams in the United States and in Brazil. Based on this evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were not effective due to two material weaknesses in Nextel Brazil's internal control over financial reporting. One of the material weaknesses was initially disclosed during the three months ended September 30, 2014 and relates to certain deficiencies in Nextel Brazil's control environment and risk assessment processes, including an organizational structure with insufficiently trained resources and where supervisory roles, responsibilities and monitoring activities were not aligned with financial reporting objectives. Our remediation efforts related to this material weakness are ongoing. Our current efforts are focused on monitoring the maturity of Nextel Brazil's newly implemented organizational structure and resources, as well as improving account reconciliation and review procedures.

During the three months ended March 31, 2016, management identified an additional material weakness in the Company’s internal control over financial reporting in Brazil that existed as of December 31, 2015 related to multiple control deficiencies that

33

resulted in certain expenses not being recorded in the fourth quarter of 2015. The control deficiencies include violation of procurement and payment policies, lack of tone at the top, and lack of communication regarding the entry into a significant arrangement by Nextel Brazil senior management. We have amended our disclosures of material weaknesses in our Item 9A. assessment of internal control over financial reporting as of December 31, 2015 in a Form 10-K/A dated May 10, 2016. As discussed further in Note 1 to our condensed consolidated financial statements, we corrected an immaterial error in our prior period financial statements as a result of this material weakness. The Audit Committee of our Board of Directors has hired a third party adviser to further assess the facts and assist us in the development of a remediation plan to address this material weakness.

These control deficiencies create a reasonable possibility that a material misstatement to the consolidated financial statements will not be prevented or detected on a timely basis. As a result, we performed additional procedures to mitigate the impact of these deficiencies on our condensed consolidated financial statements, including reviews and validations performed by staff at our headquarters office who were not part of the financial close process in Brazil.

Changes in Internal Control over Financial Reporting

Other than the additional material weakness described above, there have been no changes in the Company's internal control over financial reporting during the most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

34

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

Unless the context requires otherwise, "NII Holdings, Inc.," "NII Holdings," "we," "our," "us" and "the Company" refer to the combined businesses of NII Holdings, Inc. and its consolidated subsidiaries. Our unaudited condensed consolidated financial statements have been prepared under the rules and regulations of the Securities and Exchange Commission, or the SEC. While these financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements, they reflect all adjustments that, in the opinion of management, are necessary for a fair presentation of the results for interim periods. In addition, the year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. We refer to our wholly-owned Brazilian operating company, Nextel Telecomunicações Ltda., as Nextel Brazil.

You should read these condensed consolidated financial statements in conjunction with the consolidated financial statements and notes contained in our annual report on Form 10-K for the year ended December 31, 2015. You should not expect results of operations for interim periods to be an indication of the results for a full year. Our consolidated results from continuing operations in this quarterly report on Form 10-Q include the results of operations of Nextel Brazil and our corporate headquarters.

Revision of Prior Period Financial Statements. In connection with the preparation of our condensed consolidated financial statements for the three months ended March 31, 2016, we determined that an error existed in our previously issued financial statements. Specifically, selling, general and administrative expenses for the six months ended December 31, 2015 were understated by $6.9 million as the result of a failure to properly accrue expenses for services Nextel Brazil received under a management consulting services arrangement. We evaluated this error under the SEC's authoritative guidance on materiality and the quantification of the effect of prior period misstatements on financial statements, and we have determined that the impact of this error on our prior period consolidated financial statements is immaterial. However, since the correction of this error in the first quarter of 2016 would have been material to our results of operations for the three months ended March 31, 2016 and may be material to our results of operations for the year ending December 31, 2016, we revised our prior period financial statements to correct this error herein. 

As a result of the correction of this error, as of December 31, 2015, accrued expenses and other increased by $6.8 million, accumulated deficit increased by $6.9 million and accumulated other comprehensive loss decreased by $0.1 million. Although not presented herein, for the six months ended December 31, 2015, this error resulted in a $6.9 million increase to selling, general and administrative expenses, operating loss, loss from continuing operations before reorganization items and income tax benefit, net loss from continuing operations and net loss. In addition, for the six months ended December 31, 2015, the correction of this error also resulted in a $0.07 increase in both net loss from continuing operations per basic and diluted common share and net loss per basic and diluted common share. This error did not relate to any periods prior to the six months ended December 31, 2015.

Sales of Nextel Argentina and Nextel Mexico. On April 30, 2015, we completed the sale of our operations in Mexico to New Cingular Wireless, Inc., or New Cingular Wireless, an indirect subsidiary of AT&T, Inc., or AT&T. In addition, on September 11, 2015, two of our indirect subsidiaries entered into a binding agreement with Grupo Clarin S.A., or Grupo Clarin, relating to the sale of all of the outstanding equity interests of Nextel Argentina, which was completed on January 27, 2016. See Note 4 for more information on these sales. In connection with these transactions, we have presented Nextel Argentina's and Nextel Mexico's results for all periods as discontinued operations in this quarterly report on Form 10-Q.

Reorganization Accounting. In accordance with the requirements of reorganization accounting, NII Holdings adopted the provisions of fresh start accounting as of June 30, 2015 and became a new entity for financial reporting purposes. References to the "Successor Company" relate to NII Holdings on or subsequent to June 30, 2015. References to the "Predecessor Company" relate to NII Holdings prior to June 30, 2015. See Note 2 for more information regarding the implementation of fresh start accounting.

Going Concern.The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. These condensed consolidated financial statements do not include any adjustments that might result from the occurrence of the uncertainties described below.

We have an obligation to meet a net debt financial covenant in Nextel Brazil's local bank loans that will apply semiannually beginning on June 30, 2016. We have made a number of changes within our senior management team and modified our business plan to reflect our available cash resources and the impact of the current and expected economic and competitive conditions in Brazil on both our subscriber growth and revenues, and to align our costs with this revised outlook, but based on our current business plan, we believe that it is unlikely that we will satisfy the applicable financial covenant included in both of Nextel Brazil's local bank loan agreements at the June 30, 2016 measurement date. We will need to refinance or negotiate amendments to these financing arrangements or secure waivers from the lenders in order to avoid a potential default under the loan agreements. If a default occurs, the lenders could require us to repay the amounts outstanding under these arrangements, and if they were to do so, the lender of Nextel Brazil's equipment financing facility could accelerate the amount outstanding under that obligation as well. As of March 31, 2016, we had $256.5 million principal amount outstanding under Nextel Brazil's local bank loans and $318.0 million principal amount outstanding under Nextel Brazil’s equipment financing facility. See Note 6 for more information.

Because it is unlikely that we will satisfy the applicable financial covenant included in both of Nextel Brazil's local bank loans and because of the cross-default provisions included in Nextel Brazil's equipment financing facility as described above, we concluded that the circumstances described above continue to raise substantial doubt about our ability to continue as a going concern as of March 31, 2016.

Reclassifications. We have reclassified some prior period amounts in our condensed consolidated financial statements to conform to our current year presentation.

New Accounting Pronouncements.  In March 2016, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update, or ASU, No. 2016-09, “Improvements to Employee Share-Based Payment Accounting,” which includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. We early adopted this ASU in the first quarter of 2016. Under the new guidance, we made an accounting policy election to recognize the impact of forfeited awards on compensation expense when they occur, rather than initially reducing expense for an estimate of future forfeitures. This policy was applied using a modified retrospective approach and resulted in an immaterial cumulative effect adjustment to retained earnings.

Emergence From Chapter 11 Proceedings and Fresh Start Accounting

Reorganizations [Abstract]

Emergence from Chapter 11 Proceedings and Fresh Start Accounting

Emergence from Chapter 11 Proceedings and Fresh Start Accounting

On September 15, 2014, we and eight of our U.S. and Luxembourg-domiciled subsidiaries, including NII Capital Corp. and NII International Telecom, S.C.A., or NIIT, filed voluntary petitions seeking relief under Chapter 11 of Title 11 of the United States Bankruptcy Code, which we refer to as Chapter 11, in the United States Bankruptcy Court for the Southern District of New York, which we refer to as the Bankruptcy Court. In addition, subsequent to September 15, 2014, five additional subsidiaries of NII Holdings, Inc. filed voluntary petitions seeking relief under Chapter 11 in the Bankruptcy Court. We refer to the companies that filed voluntary petitions seeking relief under Chapter 11 collectively as the Debtors. Nextel Brazil and our previous other operating subsidiaries in Latin America were not Debtors in these Chapter 11 cases.

On June 19, 2015, the Bankruptcy Court entered an order approving and confirming the First Amended Joint Plan of Reorganization Proposed by the Plan Debtors and the Official Committee of Unsecured Creditors, dated April 20, 2015. We refer to this plan, as amended, as the Plan of Reorganization. On June 26, 2015, the conditions of the Bankruptcy Court's order and the Plan of Reorganization were satisfied, the Plan of Reorganization became effective, and we and the other Debtors emerged from the Chapter 11 proceedings. We refer to June 26, 2015 as the Emergence Date.

The significant transactions that occurred on the Emergence Date in connection with the effectiveness of our Plan of Reorganization included the following:

• NII Holdings canceled all shares of its common stock, preferred stock and other equity interests that existed prior to June 26, 2015;

• NII Holdings amended and restated its Bylaws and filed an Amended and Restated Certificate of Incorporation authorizing the Company to issue up to 140,000,000 shares of common stock, par value $0.001 per share, and up to 10,000,000 shares of undesignated preferred stock, par value $0.001 per share;

• NII Holdings issued 99,999,992 shares of new common stock, with a per share value of $20.68, and distributed cash of $776.3 million to the holders of claims and service providers in comprehensive settlement of numerous integrated claims and disputes approved by the Bankruptcy Court in connection with the confirmation of the Plan of Reorganization;

• In accordance with the Plan of Reorganization, all of the obligations of the Debtors with respect to the following indebtedness were canceled:

• $700.0 million aggregate principal amount of 7.875% senior notes due 2019 issued by NIIT pursuant to an indenture, dated as of May 23, 2013, among NIIT (as issuer), the Company (as guarantor), and Wilmington Trust National Association (as trustee) and all amendments, supplements or modifications thereto and extensions thereof;

• $900.0 million aggregate principal amount of 11.375% senior notes due 2019 issued by NIIT pursuant to an indenture, dated as of February 19, 2013, among NIIT (as issuer), the Company (as guarantor), and Wilmington Trust National Association (as trustee) and all amendments, supplements or modifications thereto and extensions thereof;

• $1.45 billion aggregate principal amount of 7.625% senior notes due 2021 issued by NII Capital Corp. pursuant to an indenture, dated as of March 29, 2011, among NII Capital Corp. (as issuer), each of the guarantors party thereto and Wilmington Savings Fund Society, FSB (as successor trustee) and all amendments, supplements or modifications thereto and extensions thereof;

• $500.0 million aggregate principal amount of 8.875% senior notes due 2019 issued by NII Capital Corp. pursuant to an indenture, dated as of December 15, 2009, among NII Capital Corp. (as issuer), each of the guarantors party thereto and U.S. Bank National Association (as successor trustee) and all amendments, supplements or modifications thereto and extensions thereof; and

• $800.0 million aggregate principal amount of 10.0% senior notes due 2016 issued by NII Capital Corp. pursuant to an indenture, dated as of August 18, 2009, among NII Capital Corp. (as issuer), each of the guarantors party thereto and Wilmington Savings Fund Society, FSB (as successor trustee) and all amendments, supplements or modifications thereto and extensions thereof.

In connection with our emergence from Chapter 11, we were required to apply the provisions of fresh start accounting to our financial statements. Because our results of operations during the period from June 26, 2015 to June 30, 2015 were not material, we applied fresh start accounting to our consolidated financial statements as of the close of business on June 30, 2015. Under the principles of fresh start accounting, a new reporting entity is considered to be created, and as a result, we allocated the reorganization value of NII Holdings as of June 30, 2015 to our individual assets based on their estimated fair values at the date we applied fresh start accounting.

Reorganization items for the three months ended March 31, 2016 were immaterial. Reorganization items for the three months ended March 31, 2015 consisted of $13.6 million in Chapter 11-related professional fees and other costs.

In connection with the completion of the sale of Nextel Communications Argentina, S.R.L., or Nextel Argentina, to Grupo Clarin in January 2016, the promissory note that was initially issued in connection with this transaction was canceled. See Note 4 for more information. Other than the cancellation of this promissory note in the first quarter of 2016, we did not have any non-cash investing or financing activities during the three months ended March 31, 2016 or 2015.

Revenue-Based Taxes. We record certain revenue-based taxes and other excise taxes on a gross basis as a component of both service and other revenues and selling, general and administrative expenses in our condensed consolidated financial statements. For the three months ended March 31, 2016 and 2015, we recognized $13.7 million and $17.8 million, respectively, in revenue-based taxes and other excise taxes, respectively.

Diluted Net Loss Per Common Share. As presented for the three months ended March 31, 2016 and 2015, our calculation of diluted net loss from continuing operations per common share is based on the weighted average number of common shares outstanding during those periods and does not include other potential common shares, including shares issuable upon the potential exercise of stock options under our stock-based employee compensation plans or restricted common shares issued under those plans since their effect would have been antidilutive.

For the three months ended March 31, 2016, we did not include 3.7 million stock options and 0.9 million restricted common shares in our calculation of diluted net loss from continuing operations per common share because their effect would have been antidilutive. In addition, for the three months ended March 31, 2015, we did not include 5.3 million stock options and 0.7 million restricted common shares in our calculation of diluted net loss from continuing operations per common share because their effect would have been antidilutive.

Discontinued Operations

Sale of Nextel Argentina. On September 11, 2015, NII Mercosur Telecom, S.L.U. and NII Mercosur Moviles, S.L.U., both of which are indirect subsidiaries of NII Holdings, entered into a binding agreement with Grupo Clarin relating to the sale of all of the outstanding equity interests of Nextel Argentina. This agreement provided for aggregate cash consideration of $178.0 million, of which $159.0 million was paid at signing in connection with the transfer of a 49% equity interest in Nextel Argentina and the grant of a call option that allowed Grupo Clarin or any of its affiliates to acquire the remaining 51% equity interest in Nextel Argentina upon receipt of required approvals from the regulatory authorities in Argentina. We received the remaining cash consideration in October 2015, including $6.0 million deposited in escrow to satisfy potential indemnification claims. On January 27, 2016, the agreement was amended to permit Grupo Clarin or any of it affiliates to exercise the right to acquire the remaining 51% equity interest prior to receiving regulatory approval, and Grupo Clarin and its affiliates immediately acquired the remaining 51% of Nextel Argentina for no additional proceeds.

Sale of Nextel Mexico. On April 30, 2015, we, together with our wholly-owned subsidiary NIU Holdings LLC, completed the sale of our Mexican operations to New Cingular Wireless, an indirect subsidiary of AT&T. The transaction was structured as a sale of all of the outstanding stock of the parent company of Comunicaciones Nextel de Mexico, S.A. de C.V., or Nextel Mexico, for a purchase price of $1.875 billion, including $187.5 million deposited in escrow to satisfy potential indemnification claims. The net proceeds from this sale were $1.448 billion after deducting Nextel Mexico's outstanding indebtedness and applying other specified price adjustments. The amount held in escrow is available for the indemnification of defined claims through April 2017. As of March 31, 2016, we had received notification for one indemnification claim in the amount of $6.5 million. As of March 31, 2016, we accrued an immaterial amount related to the potential settlement of this claim. We intend to vigorously contest this claim.

Sale of Nextel Chile. In August 2014, our wholly-owned subsidiaries NII Mercosur Telecom, S.L., NII Mercosur Moviles, S.L. and NII International Telecom S.C.A. completed the sale of all of the outstanding equity interests in our wholly-owned subsidiary, Nextel Chile, S.A., or Nextel Chile, to Fucata, S.A., a venture comprised of Grupo Veintitres and Optimum Advisors, for a de minimus amount.

Sale of Nextel Peru. In August 2013, our wholly-owned subsidiaries NII Mercosur Telecom, S.L. and NII Mercosur Moviles, S.L., completed the sale of all of the outstanding equity interests of our wholly-owned subsidiary, Nextel del Peru, S.A., or Nextel Peru, to Empresa Nacional de Telecomunicaciones S.A. and one of its subsidiaries, Entel Inversiones, S.A., which we refer to collectively as Entel. Entel has provided notice of potential claims for amounts greater than the $34.4 million that remained in escrow as of March 31, 2016 to satisfy these claims. We believe that the requirements for payment of certain indemnification claims have not been met at this time, and we intend to vigorously contest these claims. As of March 31, 2016, we accrued an immaterial amount related to the potential settlement of these claims. The time period for additional claims against the amount held in escrow lapsed in February 2015.

In connection with the sales of Nextel Argentina and Nextel Mexico, we have reported the results of these operating companies as discontinued operations in this quarterly report on Form 10-Q. Accordingly, we reclassified Nextel Argentina's and Nextel Mexico's results of operations for all periods presented to reflect these former operating companies as discontinued operations. Unless otherwise noted, amounts included in these notes to our condensed consolidated financial statements exclude amounts attributable to discontinued operations.

Impairment, Restructuring and Other Charges

Asset Impairments.

During the first quarter of 2016, we reviewed our Nextel Brazil segment for potential impairment using a probability-weighted cash flow analysis. Our estimation of undiscounted future cash flows was partially based on assumptions that we will be able to fund our business plan and that it is not probable that our Nextel Brazil segment will be disposed of. Based on our current estimated undiscounted future cash flows, we determined that the carrying value of our Nextel Brazil segment is recoverable. 

During the three months ended March 31, 2015, Nextel Brazil recognized $3.7 million in non-cash asset impairment charges, the majority of which related to the shutdown or abandonment of certain transmitter and receiver sites that are no longer required in its business.

Restructuring Charges.

During the three months ended March 31, 2016, we recognized $1.3 million in severance and other related costs at the corporate level as a result of the separation of employees in an effort to streamline our organizational structure and reduce general and administrative expenses. During the three months ended March 31, 2016, Nextel Brazil recognized $3.2 million in restructuring charges primarily related to future lease costs for certain transmitter and receiver sites that are no longer required in its business and certain office closures. Nextel Brazil recognized $2.0 million in restructuring charges during the three months ended March 31, 2015 related to similar streamlining and cost reduction efforts.

Total impairment, restructuring and other charges for the three months ended March 31, 2016 and 2015 were as follows (in thousands):

	Successor Company		Predecessor Company

Debt

As a result of the implementation of fresh start accounting in connection with our emergence from Chapter 11, we remeasured the components of our debt to their fair values as of June 30, 2015. As a result, the carrying values of our bank loans and equipment financing facility do not represent their respective outstanding principal balances. The components of our debt are as follows:

	Successor Company
	March 31, 2016			December 31, 2015
	(in thousands)
Brazil equipment financing facility	$	315,565		$	339,850

	$	90,279		$	82,647

Brazil Bank Loans. In February 2015, Nextel Brazil and the lenders providing its local bank loans entered into standstill amendments which provided for a "covenant holiday" through December 31, 2015, during which time we were not required to comply with the financial covenants outlined in Nextel Brazil's local bank loan agreements. Going forward, Nextel Brazil must maintain a net debt to earnings before interest, taxes, depreciation and amortization, or EBITDA, ratio over the trailing 12 months of no greater than 4.0 as of June 30, 2016, 3.5 as of December 31, 2016 and 2.5 as of June 30, 2017 and on each six-month anniversary thereafter.

In connection with our emergence from Chapter 11, we made a number of changes within our senior management team and modified our business plan to reflect our available cash resources and the impact of the current and expected economic and competitive conditions in Brazil on both our subscriber growth and revenues, and to align our costs with this revised outlook. Based on our current business plan, we believe that it is unlikely that we will satisfy the applicable financial covenant included in both of Nextel Brazil's local bank loan agreements at the June 30, 2016 measurement date.

We will need to refinance or negotiate amendments to these financing arrangements or secure waivers from the lenders in order to avoid a potential default under the loan agreements. If a default occurs, the lenders could require us to repay the amounts outstanding under these arrangements. As a result of this uncertainty, we have continued to classify the amounts outstanding under Nextel Brazil's local bank loans as current liabilities in our condensed consolidated balance sheet as of March 31, 2016. As of March 31, 2016, we had $256.5 million principal amount outstanding under Nextel Brazil's local bank loans.

Brazil Equipment Financing Facility. In December 2014, Nextel Brazil and the lender under its equipment financing facility agreed to amend this facility to remove all financial covenants beginning with the December 31, 2014 measurement date through the June 30, 2017 measurement date so that the first measurement date under the amended facility will be December 31, 2017. Because of the uncertainty regarding our ability to meet the financial covenant contained in Nextel Brazil's local bank loans discussed above and certain cross-default provisions that are included in the loan agreement under Nextel Brazil's equipment financing facility, we have continued to classify the amount outstanding under this facility as a current liability in our condensed consolidated balance sheet as of March 31, 2016. As of March 31, 2016, we had $318.0 million in principal amount outstanding under Nextel Brazil's equipment financing facility. We do not have the ability to borrow additional amounts under this equipment financing facility.

Fair Value Measurements

Nextel Argentina.

On September 11, 2015, two of our indirect subsidiaries entered into a binding agreement with Grupo Clarin relating to the sale of all of the outstanding equity interests of Nextel Argentina. In connection with the initial agreement, we issued a non-recourse promissory note in the amount of $85.0 million and pledged the remaining 51% of the equity interests in Nextel Argentina to Grupo Clarin. As of December 31, 2015, we recorded our retained 51% interest in Nextel Argentina as an equity method investment under the fair value option, which was included as a component of other assets in our consolidated balance sheet. As of December 31, 2015, we estimated the fair value of this investment to be $108.1 million. In addition, as of December 31, 2015, we recorded the non-recourse promissory note as a component of other long-term liabilities in our consolidated balance sheet at its estimated fair value of $108.1 million. This fair value estimate was based on the $178.0 million purchase price paid by Grupo Clarin, as adjusted for changes in excess cash from September 11, 2015 through December 31, 2015. On January 27, 2016, the agreement was amended to permit Grupo Clarin or any of its affiliates to exercise the right to acquire the remaining 51% equity interest prior to receiving regulatory approval, and Grupo Clarin and its affiliate immediately acquired the remaining 51% of Nextel Argentina for no additional proceeds. In connection with the completion of this transaction, the promissory note was canceled on January 27, 2016.

Financial Instruments.

Available-for-Sale Securities.

As of March 31, 2016 and December 31, 2015, available-for-sale securities held by Nextel Brazil included $23.7 million and $56.2 million, respectively, in investment funds and $10.5 million and $9.3 million, respectively, in certificates of deposit with a Brazilian bank. These funds invest primarily in Brazilian government bonds, long-term, low-risk bank certificates of deposit and Brazilian corporate debentures. During the three months ended March 31, 2016 and 2015, we did not have any material unrealized gains or losses associated with these investments.

We account for our available-for-sale securities at fair value. The fair value of our Brazilian certificates of deposit is based on their current redemption amount, and we classify these certificates of deposit within Level 2 of the fair value hierarchy. The fair value of Nextel Brazil's investment funds is measured based on the funds' net asset value as a practical expedient, which is excluded from the fair value hierarchy.

Held-to-Maturity Investments.

We periodically invest some of our cash holdings in certain securities that we intend to hold to maturity. As of December 31, 2015, held-to-maturity investments included $18.1 million in short-term investments held by NIIT in U.S. treasury notes. We account for held-to-maturity securities at amortized cost, which approximates the fair value observed in the market. As of December 31, 2015, the fair value of our held-to-maturity investments was $18.0 million. These securities matured in February 2016.

Debt Instruments.

The carrying amounts and estimated fair values of our debt instruments are as follows:

	Successor Company
	March 31, 2016						December 31, 2015
	Principal Amount Outstanding		Carrying Amount		Estimated Fair Value		Principal Amount Outstanding		Carrying Amount		Estimated Fair Value
	(in thousands)
Brazil equipment financing	$	318,012	$	315,565	$	316,129	$	342,475	$	339,850	$	340,189
Brazil bank loans and other	257,062		263,525		264,553		234,320		240,922		229,366
	$	575,074	$	579,090	$	580,682	$	576,795	$	580,772	$	569,555

Bank loans and other consists primarily of loans with certain banks in Brazil. We estimated the fair value of these bank loans, as well as the fair value of our equipment financing facility in Brazil, utilizing inputs such as U.S. Treasury security yield curves, prices of comparable bonds, LIBOR, U.S. Treasury bond rates and credit spreads on comparable publicly traded bonds. We consider both Nextel Brazil's equipment financing facility and its bank loans and other to be Level 3 in the fair value hierarchy.

Derivative Instruments.

We occasionally enter into derivative transactions for risk management purposes. We have not and will not enter into any derivative transactions for speculative or profit generating purposes. We record all derivative instruments as either assets or liabilities on our condensed consolidated balance sheet at their fair value. As of March 31, 2016 and December 31, 2015, Nextel Brazil had an immaterial amount of derivative instruments that were classified as short-term investments on our condensed consolidated balance sheet. We consider this measurement to be Level 3 in the fair value hierarchy. Nextel Brazil entered into foreign currency option agreements to manage the foreign currency exposures associated with the forecasted purchase of handsets and other U.S. dollar-denominated payments. We do not apply hedge accounting to these derivative instruments. As a result, we have included all changes in the fair value of these instruments as a component of other (expense) income, net in our condensed consolidated statement of comprehensive income (loss). The gains and losses recognized in the three months ended March 31, 2016 were not material. For the three months ended March 31, 2015, Nextel Brazil recognized $9.9 million in unrealized gains resulting from the changes in the estimated fair value of these derivative instruments.

Other Financial Instruments.

The carrying values of cash and cash equivalents, accounts receivable and accounts payable contained in our condensed consolidated balance sheets approximate their fair values due to the short-term nature of these instruments.

Commitments and Contingencies [Abstract]

Commitments and Contingencies

Commitments and Contingencies

Handset, Equipment and Other Commitments.

We are a party to purchase agreements with various suppliers under which we have committed to purchase handsets, equipment and network services that will be used or sold in the ordinary course of business. As of March 31, 2016, we are committed to purchase $171.6 million under a handset purchase agreement with one of our handset suppliers by the end of 2016. We do not expect that we will purchase all of the committed devices, but we have not recorded a liability for this contract because we do not believe it is probable that we will incur a loss under this handset purchase agreement.

Brazil Spectrum Commitment.

In December 2015, Nextel Brazil participated in a spectrum auction and was the successful bidder for 30 megahertz, or MHz, of spectrum in the 1.8 gigahertz, or GHz, band for 455.0 million Brazilian reais, or approximately $116.7 million based on foreign currency exchange rates at the time. Nextel Brazil received the license agreement on February 16, 2016 and is committed to pay 10% of the total acquisition price when this license agreement is signed.

Contingencies.

Nextel Brazil has received various assessment notices from state and federal Brazilian authorities asserting deficiencies in payments related primarily to value-added taxes, excise taxes on imported equipment and other non-income based taxes. Nextel Brazil has filed various administrative and legal petitions disputing these assessments. In some cases, Nextel Brazil has received favorable decisions, which are currently being appealed by the respective governmental authority. In other cases, Nextel Brazil's petitions have been denied, and Nextel Brazil is currently appealing those decisions. Nextel Brazil also had contingencies related to certain regulatory, civil and labor-related matters as of March 31, 2016 and December 31, 2015.

As of March 31, 2016 and December 31, 2015, Nextel Brazil had accrued liabilities of $58.5 million and $57.7 million, respectively, related to contingencies, of which $4.6 million and $5.4 million related to unasserted claims, respectively. We currently estimate the reasonably possible losses related to matters for which Nextel Brazil has not accrued liabilities, as they are not deemed probable, to be approximately $305.0 million as of March 31, 2016. We continue to evaluate the likelihood of probable and reasonably possible losses, if any, related to all known contingencies. As a result, future increases or decreases to our accrued liabilities may be necessary and will be recorded in the period when such amounts are determined to be probable and reasonably estimable.

In addition, as of March 31, 2016, we estimated the reasonably possible losses related to potential indemnification claims in connection with the sales of Nextel Mexico and Nextel Peru for which we have not accrued liabilities, as they are not deemed probable, to be approximately $41.0 million.

Legal Proceedings.

We are subject to claims and legal actions that may arise in the ordinary course of business. We do not believe that any of these pending claims or legal actions will have a material effect on our business, financial condition, results of operations or cash flows.

Income Taxes

Income Taxes

The realization of deferred tax assets is dependent on the generation of future taxable income sufficient to realize our tax loss carryforwards and other tax deductions. Valuation allowances are required to be recognized on deferred tax assets unless it is determined that it is “more-likely-than-not” that the asset will be realized. In 2015, we recorded full valuation allowances on the deferred tax assets of our foreign operating companies, our U.S. parent company and subsidiaries and our foreign holding companies due to substantial negative evidence such as the recent history of cumulative losses and the projected losses for 2016 and subsequent years. We maintained this same valuation allowance position through the first three months of 2016.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Revenue-Based Taxes

Revenue-Based Taxes. We record certain revenue-based taxes and other excise taxes on a gross basis as a component of both service and other revenues and selling, general and administrative expenses in our condensed consolidated financial statements. For the three months ended March 31, 2016 and 2015, we recognized $13.7 million and $17.8 million, respectively, in revenue-based taxes and other excise taxes, respectively.

Diluted Net (Loss) Income Per Common Share

Diluted Net Loss Per Common Share. As presented for the three months ended March 31, 2016 and 2015, our calculation of diluted net loss from continuing operations per common share is based on the weighted average number of common shares outstanding during those periods and does not include other potential common shares, including shares issuable upon the potential exercise of stock options under our stock-based employee compensation plans or restricted common shares issued under those plans since their effect would have been antidilutive.

For the three months ended March 31, 2016, we did not include 3.7 million stock options and 0.9 million restricted common shares in our calculation of diluted net loss from continuing operations per common share because their effect would have been antidilutive. In addition, for the three months ended March 31, 2015, we did not include 5.3 million stock options and 0.7 million restricted common shares in our calculation of diluted net loss from continuing operations per common share because their effect would have been antidilutive.
