RISK FACTORS

You should consider the following risks as well as the other information set forth in this prospectus when evaluating an investment in our company. In general, investing in the securities of issuers in emerging market countries, such as Brazil, involves a higher degree of risk than investing in the securities of issuers in the United States. Additional risks and uncertainties not currently known to us, or those that we currently deem to be immaterial, may also materially and adversely affect our business, results of operations, financial condition and prospects. Any of the following risks could materially affect us. In such case, you may lose all or part of your original investment.

Risks Relating to the Rights Offer

Common ADS Rights and Common Share Rights that are not exercised prior to the Common ADS Rights Expiration Time or Share Rights Expiration Time, respectively, will expire valueless without any compensation, and if you do not exercise your Common ADS Rights or Common Share Rights, you will suffer significant dilution of your percentage ownership of Common ADSs or Common Shares, as the case may be.

Holders of Common ADS Rights will be entitled to exercise their Common ADS Rights during the period commencing at 9:00 a.m. on                 and ending at 5:00 p.m. on                 . Holders of Common Share Rights will be entitled to exercise their Common Share Rights during the period commencing at 9:00 a.m. (Brasília time) on                 and ending at 5:00 p.m. (Brasília time) on                 . Any Common ADS Rights or Common Share Rights that remain unexercised at the end of the applicable period will expire valueless without any compensation.

The Rights Offer will result in our issuance of an additional                  Common Shares, directly or in the form of ADSs. To the extent that you do not exercise your Common ADS Rights or Common Share Rights, as applicable, your proportionate ownership and voting interest in us will, accordingly, be reduced, and the percentage that your current holdings of Common ADSs or Common Shares represent of our increased share capital after completion of the Rights Offer will be disproportionately reduced. See “Dilution.” Even if you elect to sell your Common ADS Rights or Common Share Rights, the consideration you receive for them may not be sufficient to fully compensate you for the dilution of your percentage ownership of the Common ADSs or Common Shares, as applicable, that may be caused as a result of the Rights Offer.

The market prices of Common ADSs and Common Shares may fluctuate and may fall below the subscription price of the New Common ADSs and New Common Shares, respectively, issued upon the exercise of Common ADS Rights and Common Share Rights, respectively.

The market prices of the Common ADSs or Common Shares could be subject to significant fluctuations. Such risks depend on the market’s perception of the likelihood of completion of the Rights Offer, on sales of New Common ADSs and New Common Shares in the market during the Rights Offer or the impression that such sales will take place and/or in response to various facts and events, including any regulatory changes affecting our operations, variations in our operating results and business developments and/or those of our competitors. Stock markets have, from time to time, experienced significant price and volume fluctuations that have affected the market prices for securities and which may be unrelated to our financial condition, operating performance or prospects. Furthermore, our financial condition, operating results and prospects from time to time may be below the expectations of market analysts and investors. Any of these events could result in a decline in the market price of the Common ADSs and Common Shares.

Table of Contents

We cannot assure you that the public trading market price of the Common ADSs and Common Shares will not decline below the exercise price after you elect to exercise your rights. If that occurs, because your subscription for New Common ADSs is irrevocable and may not be cancelled or modified, you will have committed to buy New Common ADSs at a price above the prevailing market price, and you will suffer an immediate unrealized loss on those New Common ADSs as a result. Moreover, we cannot assure you that following the exercise of rights you will be able to sell your New Common ADSs or New Common Shares at a price equal to or greater than the exercise price.

The Rights Offer may cause the price of the Common ADSs and Common Shares to decrease.

Depending upon the trading price of the Common ADSs and Common Shares at the time of our announcement of the Rights Offer and its terms, including the subscription price, together with the number of Common Shares we propose to issue and ultimately will issue if the Rights Offer is completed, the Rights Offer may result in an immediate decrease in the market value of the Common ADSs and Common Shares. This decrease may continue after the completion of the Rights Offer. If that occurs, you may have committed to buy Common ADSs and/or Common Shares in the Rights Offer at a price greater than the prevailing market price. Further, if a substantial number of Common ADS Rights and/or Common Share Rights are exercised and the holders of the New Common ADSs and/or New Common Shares received upon exercise of those rights choose to sell some or all of those New Common ADSs and/or New Common Shares, the resulting sales could depress the market price of the Common ADSs and Common Shares. Your purchase of New Common ADSs and/or New Common Shares in the Rights Offer may be at a price greater than the prevailing trading price. There is no assurance that following the exercise of your rights you will be able to sell your New Common ADSs and/or New Common Shares at prices equal to or greater than the applicable subscription prices.

No prior market exists for the Common ADS Rights or the Common Share Rights.

Although they will be transferable, the Common ADS Rights and Common Share Rights will be a new issue of securities with no established trading market. Unless exercised, the Common ADS Rights and the Common Share Rights will cease to have any value following the Common ADS Rights Expiration Time and the Share Rights Expiration Time, respectively.

Although we anticipate that the Common ADSs Rights will be eligible to trade on the NYSE beginning at 9:30 a.m. (New York City time) on                 , until 4:00 p.m. (New York City time) on                 , we can give no assurance that a market for the Common ADSs Rights will develop or, if a market does develop, as to how long it will continue or at what prices the rights will trade.

Although we anticipate that the Common Share Rights will be eligible to trade on the B3 from 9:00 a.m. (Brasília time) on                 to 5:00 p.m. (Brasília time) on                  , we can give no assurance that a market for the Common Share Rights will develop or, if a market does develop, as to how long it will continue or at what prices the rights will trade.

The New Common Share Subscription Price is not an indication of our market value.

Each Common ADS Right will entitle its holder to subscribe for one New Common ADS at an exercise price of the U.S. dollar equivalent of R$                . Each Common Share Right will entitle its holder to subscribe for one New Common Share at an exercise price of R$                . The exercise price has been determined based on a formula set forth in the RJ Plan and the Commitment Agreement, which resulted from independent negotiations between Oi and the Backstop Investors, and also considering the interests of our current shareholders. The New Common Share Subscription Price does not bear a direct relationship to the book value of our assets or the market value of our shares. Our Common ADSs and Common Shares may trade at prices lower than the respective subscription prices in the future.

You may not receive all of the Excess New Common ADSs and/or Excess New Common Shares you apply for in the Rights Offer.

Holders of Common ADS Rights and Commons Share Rights may manifest their intention to subscribe for Excess New Common ADSs and Excess New Common Shares, respectively, in the event that the Rights Offer is not fully subscribed pursuant to the exercise of rights initially allocated to holders of our existing Common ADSs and Preferred ADSs and existing Common Shares and Preferred Shares. If an insufficient number of Excess New Common ADSs and Excess New Common Shares are available to fully satisfy all excess applications, the available Excess New Common ADSs and Excess New Common Shares will be distributed on a pro rata basis as described in “The Offering—Subscription by Holders of Common ADSs and Preferred ADSs—Excess New Common ADSs” and “—Subscription by Holders of Common Shares and Preferred Shares—Excess New Common Shares.”

If you are a holder of Common ADS Rights, you will not be able to revoke the exercise of your subscription rights for New Common ADSs.

Unlike holders of Common Share Rights with respect to subscriptions for New Common Shares, holders of Common ADS Rights do not have withdrawal rights with respect to subscriptions for New Common ADSs. Therefore, even if circumstances arise after you have subscribed in the ADS Rights Offer that cause you to change your mind about subscribing for New Common ADSs, you will nonetheless be legally bound to proceed with your investment.

You need to act promptly and follow subscription instructions, otherwise your exercise of rights may be rejected and your rights may expire without value and without any compensation.

Holders who desire to exercise rights or apply for excess rights in the Rights Offer must act promptly to ensure that all required forms, letters and payments are actually received by the relevant agents prior to the Common ADS Rights Expiration Time or the Share Rights Expiration Time, as the case may be. If you fail to complete and sign the required acceptance forms or letters, send an incorrect payment amount, or otherwise fail to follow the procedures that apply to your desired transaction, your broker or other securities intermediary, the ADS Rights Agent or the B3 may reject all or part of your exercise of rights and any unexercised rights will expire without value and without any compensation. None of Oi, the Rights Agent or the B3 undertakes to contact you concerning, or attempt to correct, an incomplete or incorrect acceptance form, letter or payment. We have sole discretion to determine whether an exercise of rights and acceptance of or subscription for New Common ADSs or New Common Shares properly follows the appropriate procedures. If you hold Common ADSs, Preferred ADSs, Common Shares or Preferred Shares through a broker or other securities intermediary, you are urged to consult your broker or other securities intermediary without delay regarding the procedure you need to follow for the subscription and payment for New Common ADS and/or New Common Shares.

Brazilian tax laws may have an adverse impact on the taxes applicable to the disposition of Common Share Rights and Common ADS Rights.

According to Law No. 10,833, enacted on December 29, 2003, if a holder not deemed to be domiciled in Brazil for Brazilian tax and regulatory purposes, or a Non-Brazilian Holder, disposes of assets located in Brazil, the transaction will be subject to taxation in Brazil, even if such disposition occurs outside Brazil or if such disposition is made to another Non-Brazilian Holder. Accordingly, on the disposition of Common Share Rights, which are considered assets located in Brazil, the Non-Brazilian Holder will be subject to income tax on the gains assessed, following the rules described under “Taxation—Certain Brazilian Tax Considerations—Taxation of Gains,” regardless of whether the transactions are conducted in Brazil or abroad and with a Brazilian resident or not. A disposition of Common ADS Rights between Non-Brazilian Holders, however, involves the disposal of a non- Brazilian asset and in principle is currently not subject to taxation in Brazil. Nevertheless, in the event that the concept of “disposition of assets” is interpreted to include the disposition between Non-Brazilian Holders of assets located outside Brazil, this tax law could result in the imposition of withholding taxes in the event of a disposition of Common ADS Rights made by Non-Brazilian Holders. Due to the fact that, as of the date of this prospectus, Law No. 10,833/2003 has no judicial guidance as to its application, we are unable to predict whether an interpretation applying such tax laws to dispositions of Common ADS Rights between Non-Brazilian Holders could ultimately prevail in Brazilian courts. For more information, see “Taxation—Certain Brazilian Tax Considerations—Taxation of Gains.”

Your receipt or disposition of Common ADS Rights or Common Share Rights may be treated as a taxable distribution to you.

Your receipt of Common ADS Rights or Common Share Rights pursuant to the Rights Offer should be treated as a non-taxable distribution with respect to your existing Common ADSs, Preferred ADSs, Common Shares or Preferred Shares for U.S. federal income tax purposes. However, this conclusion is not free from doubt, and it is possible that subsequent events, such as certain distributions from Oi made within 36 months of the issuance date of the Common ADS Rights and Common Share Rights, could cause U.S. holder to be subject to tax on the fair market value of the Common ADS Rights and Common Share Rights. Additionally, it is possible that the Internal Revenue Service may take a contrary view and require a U.S. holder to include in income the fair market value of Common ADS Rights and Common Share Rights on the date of their distribution. For more information, see “Taxation—Certain United States Federal Income Tax Considerations—Taxation of Rights—Receipt of Rights in the Rights Offer.”

In addition, subject to the passive foreign investment company, or PFIC, rules discussed under “Taxation—Certain United States Federal Income Tax Considerations—Taxation of New Shares—PFIC Rules,” if you sell, exchange or otherwise dispose of your Common ADS Rights or Common Share Rights in a taxable disposition, you will recognize gain or loss for U.S. federal income tax purposes equal to the difference between the amount realized and your tax basis in your Common ADS Rights or Common Share Rights, if any, determined in U.S. dollars. Such gain or loss generally will be long-term capital gain or loss if the Common ADS Rights or Common Share Rights are deemed held for more than one year. Long-term capital gains realized by certain U.S. holders (including individuals) are eligible for taxation at reduced rates. Your holding period in the Common ADS Rights or Common Share Rights    will include your holding period in the existing Common ADSs, Preferred ADSs, Common Shares or Preferred Shares with respect to which the Common ADS Rights or Common Share Rights, as the case may be, were distributed. Your gain or loss will generally be income or loss from sources within the United States for foreign tax credit limitation purposes. The deductibility of capital losses is subject to limitations. For more information, see “Taxation—Certain United States Federal Income Tax Considerations—Taxation of Rights—Sale, Exchange or Other Taxable Disposition of Rights.”

Each holder of Common ADSs, Preferred ADSs, Common Shares and Preferred Shares is urged to consult his, her or its own tax advisor with respect to the particular tax consequences of the Rights Offer.

Risks Relating to Our Financial Restructuring

If we fail to comply with certain conditions subsequent set forth in the RJ Plan, the RJ Plan may terminate and we may be declared bankrupt under Brazilian law and liquidated.

On June 20, 2016, Oi, together with the other RJ Debtors, filed a joint voluntary petition for judicial reorganization pursuant to the Brazilian Bankruptcy Law with the RJ Court, pursuant to an urgent measure approved by our board of directors. On December 19 and 20, 2017, the GCM was held to consider approval of the most recently filed judicial reorganization plan. The GCM concluded on December 20, 2017 following the approval of the RJ Plan reflecting amendments to the judicial reorganization plan presented at the GCM as negotiated during the course of the GCM. On January 8, 2018, the RJ Court entered the Brazilian Confirmation Order, ratifying and confirming the RJ Plan, according to its terms, but modifying certain provisions of the RJ Plan. The Brazilian Confirmation Order was published in the Official Gazette of the State of Rio de Janeiro on February 5, 2018, the Brazilian Confirmation Date. For more information with respect to the RJ Proceedings, see “Business—Our Judicial Reorganization Proceedings.”

The Brazilian Confirmation Order, according to its terms, is currently binding on all parties, although it is subject to pending appeals with no suspensive effect attributed to it. By operation of the RJ Plan and the Brazilian Confirmation Order, provided that the Brazilian Confirmation Order is not overturned or altered as a result of the pending appeals, the unsecured claims against the RJ Debtors have been novated and discharged under Brazilian law and holders of such claims are entitled only to receive the recoveries set forth in the RJ Plan in exchange for their claims in accordance with the terms and conditions of the RJ Plan. As of the date of this prospectus, there are several appeals of the Brazilian Confirmation Order pending (see “Business—Our Judicial Reorganization Proceedings—Confirmation of Judicial Reorganization Plan by RJ Court”). For more information with respect to the recoveries available with respect to claims against the RJ Debtors provided for in the RJ Plan, see “Business—Our Judicial Reorganization Proceedings—Implementation of the Judicial Reorganization Plan” and “Management’s Discussion and Analysis of Financial Condition and Results of Operation—Prepetition Liabilities Subject to Compromise.”

Under the terms of the RJ Plan, in the event that the Rights Offer is not fully subscribed and the subscription for Unsubscribed Shares by the Backstop Investors does not close on or prior to February 28, 2019, the RJ Plan will automatically terminate and the rights and guarantees of the creditors appearing on the Second Creditors List will be restored under the original terms as if the RJ Plan had never been approved, net of amounts validly received pursuant to the RJ Plan as of the termination date, in accordance with Brazilian Bankruptcy Law, unless creditors agree by a simple majority vote of the amount of claims present or represented at a meeting of creditors called for that purpose to the total or partial waiver or modification of the conditions described above. If the RJ Plan is terminated, creditors will be entitled to (1) approve a modification to the RJ Plan at a meeting of creditors complying with the quorum requirements established in the Brazilian Bankruptcy Law, or (2) seek to have the RJ Debtors adjudicated as bankrupt by the RJ Court.

We cannot assure you that the Rights Offer will be fully subscribed and the subscription for Unsubscribed Shares by the Backstop Investors will close on or prior to February 28, 2019, or that our creditors will agree to a waiver of this condition in the event that this transaction do not occur on a timely basis. As a result, the RJ Plan may automatically terminate. In the event that the RJ Plan terminates, we cannot predict (1) whether our creditors will be able to agree on a modification to the RJ Plan that will garner sufficient support to be approved by our creditors and confirmed by the RJ Court, (2) what modifications of the RJ Plan could be adopted and the impact of these modifications on our company, or (3) whether our creditors would seek to have the RJ Debtors adjudicated as bankrupt by the RJ Court, which under Brazilian law is generally followed by a liquidation of the debtors. The termination of the RJ Plan and the occurrence of any of these events subsequent to such termination is likely to have a material adverse effect on our business, financial condition, results of operations and ability to continue as a going concern.

The cash capital increase of R$4 billion provided for under Section 6 of the RJ Plan may not close on or prior to February 28, 2019, which could impair our ability to implement the capital expenditures contemplated by our business plan.

Under the terms of the RJ Plan, we are required to conclude the cash capital increase of R$4 billion provided for under Section 6 of the RJ Plan, either directly through this Rights Offer or through the exercise of our rights under the Commitment Agreement, on or prior to February 28, 2019. In the event that the Rights Offer is not fully subscribed and the subscription for Unsubscribed Shares by the Backstop Investors does not close on or prior to February 28, 2019, the RJ Plan will automatically terminate and the rights and guarantees of the creditors appearing on the Second Creditors List will be restored under the original terms as if the RJ Plan had never been approved, net of amounts validly received pursuant to the RJ Plan as of the termination date, in accordance with Brazilian Bankruptcy Law, unless creditors agree by a simple majority vote of the amount of claims present or represented at a meeting of creditors called for that purpose to the total or partial waiver or modification of the conditions described above.

As part of the RJ Plan, we negotiated the terms of the Commitment Agreement with members of the Ad Hoc Group, the IBC and certain other unaffiliated bondholders under which such bondholders agreed to backstop the Rights Offer. The commitments of these parties are subject to our satisfaction of certain conditions, including, among others, our compliance with the terms of the RJ Plan and the adoption by ANATEL of a new General Plan of Universal Service Goals ( Plano Geral de Metas de Universalização) amending and/or revoking Decree No. 7,512/2011 and reducing the universal access targets applicable to switched fixed telephony concessions. We cannot assure you that each of these conditions will be met or waived by the parties to the Commitment Agreement in a timely fashion so as to permit the closing of the Commitment Agreement on or prior to February 28, 2019. In addition, the Commitment Agreement may be terminated by Backstop Investors holding more than 60% in amount of the total Backstop Commitments in the event that we have not achieved certain milestones set forth in the Commitment Agreement, some of which have not been met. We cannot assure you that the Commitment Agreement will not be terminated by action of the Backstop Investors. For more information about the Commitment Agreement and the conditions precedent thereto, see “The Offering—Backstop Commitment Agreement.”

In the event that we are unable to conclude the cash capital increase of R$4 billion provided for under Section 6 of the RJ Plan, either directly through this Rights Offer or through the exercise of our rights under the Commitment Agreement, we may be unable to fund the capital expenditures included in our business plan, which are necessary for us to modernize our infrastructure in order to successfully compete in the Brazilian telecommunications sectors. Our failure to do so is likely to have a material adverse effect on our business, financial condition, results of operations and ability to continue as a going concern.

General Risks Relating to the Telecommunications Industry

The telecommunications industry is subject to frequent changes in technology. Our ability to remain competitive depends on our ability to implement new technology, and it is difficult to predict how new technology will affect our business .

Companies in the telecommunications industry must adapt to rapid and significant technological changes that are usually difficult to anticipate. The mobile telecommunications industry in particular has experienced rapid and significant technological development and frequent improvements in capacity, quality and data-transmission speed. Technological changes may render our equipment, services and technology obsolete or inefficient, which may adversely affect our competitiveness or require us to increase our capital expenditures in order to maintain our competitive position. In addition, personal mobility service providers in Brazil are experiencing increasing competition from over-the-top, or OTT, providers, which provide content (such as WhatsApp, Skype and YouTube) over an internet connection rather than through a service provider’s network. OTT providers are becoming increasingly competitive as customers shift from mobile voice and SMS communications to internet-based voice and data communications through computers and smartphone or tablet applications. It is possible that alternative technologies may be developed that are more advanced than those we currently provide. We may not obtain the expected benefits of our investments if more advanced technologies are adopted by the market. Even if we adopt new technologies in a timely manner as they are developed, the cost of such technology may exceed the benefit to us, and we cannot assure you that we will be able to maintain our level of competitiveness.

Our operations depend on our ability to maintain, upgrade and operate efficiently our accounting, billing, customer service, information technology and management information systems and to rely on the systems of other carriers under co-billing agreements.

Sophisticated information and processing systems are vital to our growth and our ability to monitor costs, render monthly invoices for services, process customer orders, provide customer service and achieve operating efficiencies. We cannot assure you that we will be able to operate successfully and upgrade our accounting, information and processing systems or that these systems will continue to perform as expected. We have entered into co-billing agreements with each long-distance telecommunications service provider that is interconnected to our networks in Brazil to include in our invoices the long-distance services rendered by these providers, and these providers have agreed to include charges owed to us in their invoices. Any failure in our accounting, information and processing systems, or any problems with the execution of invoicing and collection services by other carriers with whom we have co-billing agreements, could impair our ability to collect payments from customers and respond satisfactorily to customer needs, which could adversely affect our business, financial condition and results of operations.

Improper use of our networks could adversely affect our costs and results of operations.

We may incur costs associated with the unauthorized and fraudulent use of our networks, including administrative and capital costs associated with detecting, monitoring and reducing the incidence of fraud. Fraud also affects interconnection costs and payments to other carriers for non-billable fraudulent roaming. Improper use of our network could also increase our selling expenses if we need to increase our provision for doubtful accounts to reflect amounts we do not believe we can collect for improperly made calls. Any increase in the improper use of our network in the future could materially adversely affect our costs and results of operations.

Our business is dependent on our ability to expand our services and to maintain the quality of the services provided.

Our business as a telecommunications services provider depends on our ability to maintain and expand our telecommunications services network. We believe that our expected growth will require, among other things:

We believe that these requirements will place significant demand on our managerial, operational and financial resources. Failure to manage successfully our expected growth could reduce the quality of our services, with adverse effects on our business, financial condition and results of operations.

Our operations are also dependent upon our ability to maintain and protect our network. Failure in our networks, or their backup mechanisms, may result in service delays or interruptions and limit our ability to provide customers with reliable service over our networks. Some of the risks to our networks and infrastructure include (1) physical damage to access lines and long-distance optical cables; (2) power surges or outages; (3) software defects; (4) disruptions beyond our control; (5) breaches of security; and (6) natural disasters. The occurrence of any such event could cause interruptions in service or reduce capacity for customers, either of which could reduce our net operating revenue or cause us to incur additional expenses. In addition, the occurrence of any such event may subject us to penalties and other sanctions imposed by ANATEL, and may adversely affect our business and results of operations.

We face various cyber-security risks that, if not adequately addressed, could have an adverse effect on our business.

We face various cyber-security risks that could result in business losses, including but not limited to contamination (whether intentional or accidental) of our networks and systems by third parties with whom we exchange data, equipment failures, unauthorized access to and loss of confidential customer, employee and/or proprietary data by persons inside or outside of our organization, cyber attacks causing systems degradation or service unavailability, the penetration of our information technology systems and platforms by ill-intentioned third parties, and infiltration of malware (such as computer viruses) into our systems. Cyber attacks against companies have increased in frequency, scope and potential harm in recent years. Further, the perpetrators of cyber attacks are not restricted to particular groups or persons. These attacks may be committed by company employees or third parties operating in any region, including jurisdictions where law enforcement measures to address such attacks are unavailable or ineffective. We may not be able to successfully protect our operational and information technology systems and platforms against such threats. Further, as cyber attacks continue to evolve, we may incur significant costs in the attempt to modify or enhance our protective measures or investigate or remediate any vulnerability. The inability to operate our networks and systems as a result of cyber attacks, even for a limited period of time, may result in significant expenses to us and/or a loss of market share to other communications providers. The costs associated with a major cyber attack could include expensive incentives offered to existing customers and business partners to retain their business, increased expenditures on cyber-security measures and the use of alternate resources, lost revenues from business interruption and litigation. If we are unable to adequately address these cyber-security risks, or operating network and information systems could be compromised, which would have an adverse effect on our business, financial condition and results of operations.

The mobile telecommunications industry and participants in this industry, including us, may be required to adopt an extensive program of field measurements of radio frequency emissions and be subject to further regulation and/or claims based on concerns regarding potential health problems and interfere with medical devices.

Media and other entities have suggested that the electromagnetic emissions from mobile handsets and base stations may cause health problems. If consumers harbor health-related concerns, they may be discouraged from using mobile handsets. These concerns could have an adverse effect on the mobile telecommunications industry and, possibly, expose mobile services providers to litigation. We cannot assure you that further medical research and studies will refute a link between the electromagnetic emissions of mobile handsets and base stations, including on frequency ranges we use to provide mobile services, and these health concerns. Government authorities could increase regulation on electromagnetic emissions of mobile handsets and base stations, which could have an adverse effect on our business, financial condition and results of operations. The expansion of our network may be affected by these perceived risks if we experience problems in finding new sites, which in turn may delay the expansion and may affect the quality of our services.

In July 2002, ANATEL enacted regulations that limit emission and exposure for fields with frequencies between 9 kHz and 300 GHz. In May 2009, Law No. 11,934 was enacted, which established the need for field measurements by telecommunications service providers of all radio-communication transmitting stations every five years with respect to emission and exposure to these fields. We expect that ANATEL will publish new regulations which provide for the reevaluation of regulations regarding human exposure to radiofrequency electromagnetic fields and the form of the field measurements mandated by Law No. 11,934 by the end of 2018. We cannot predict the scope of the technical and financial impact of these new regulations on our company.  

Risks Relating to Our Company

We have identified various material weaknesses in our internal control over financial reporting which have materially adversely affected our ability to timely and accurately report our results of operations and financial condition. These material weaknesses may not have been fully remediated as of the filing date of this prospectus and we cannot assure you that other material weaknesses will not be identified in the future.

Under the supervision and with the participation of our chief executive officer and our chief financial officer, our management conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2017 based on the criteria established in “Internal Control —Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, our management concluded that as of December 31, 2017, our internal control over financial reporting was not effective because material weaknesses existed. A material weakness is a control deficiency, or combination of control deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual consolidated financial statements will not be prevented or detected on a timely basis. These deficiencies resulted in material misstatements to the Company’s financial statements for 2015 and previous years, which were corrected through restatement of those periods, and to the preliminary 2016 and 2017 financial statements, which were corrected prior to issuance.

32

Table of Contents

The material weaknesses identified as of December 31, 2017 were: (1) we did not design, establish and maintain effective procedures to ensure adequate review, approval, and existence of sufficient supporting documentation over manual journal entries. This weakness could impact in a failure to timely detect the totality of manual journal entries, as well as their adequate approval and revision; (2) we did not design, establish or maintain effective controls over the communication of activity that impacted the judicial deposits and contingencies balances. Further, effective controls over the timely reconciliation of these accounts were not established or maintained; (3) we did not design, establish or maintain effective control over the preparation, timely review, and documented approval of the reconciliation of unbilled revenues. Specifically, we did not have effective controls over the completeness and accuracy of supporting schedules. The schedules and historical information used in this process were not reviewed in a periodic and timely manner; (4) we did not have sufficient and skilled accounting and finance personnel necessary to perform appropriate processes and controls related to the preparation of the financial statements in accordance with U.S. GAAP, which includes timely identification and review of significant non-routine transactions. As a result, a number of errors in our financial statements were detected and corrected and could not be detected on a timely basis by management in the normal course of the business; (5) we did not design, establish or maintain effective control over the completeness and accuracy of consolidation entries, which includes timely review of reconciliation of intercompany balances and its elimination in the consolidation process; and (6) we did not design, establish or maintain effective control over the process level control to capture and identify the statute of limitation of its recoverable taxes.

Although we have implemented and continue to implement measures designed to remediate these material weaknesses and, in the short term, to mitigate the potential adverse effects of these material weaknesses, our assessment of the impact of these measures has not been completed as of the filing date of this prospectus and we cannot assure you that these measures are adequate. Moreover, we cannot assure you that additional material weaknesses in our internal control over financial reporting will not arise or be identified in the future.

As a result, we must continue our remediation activities and must also continue to improve our operational, information technology, and financial systems, infrastructure, procedures, and controls, as well as continue to expand, train, retain, and manage our employee base. Any failure to do so, or any difficulties we encounter during implementation, could result in additional material weaknesses or in material misstatements in our financial statements. These misstatements could result in a future restatement of our financial statements, could cause us to fail to meet our reporting obligations, or could cause investors to lose confidence in our reported financial information, which could materially adversely affect our business, financial condition and results of operations and may generate negative market reactions, potentially leading to a decline in the price of the Common Shares and Common ADSs.

Our debt instruments contain covenants that could restrict our financing and operating flexibility and have other adverse consequences.

As of June 30, 2018 and December 31, 2017, we had loans and financings of R$32,153 million and R$49,130 million, respectively, classified as liabilities subject to compromise. Following the implementation of the RJ Plan, the outstanding amount of our loans and financings has been substantially reduced. As of June 30, 2018, we had loans and financings of R$18,419 million not classified as liabilities subject to compromise, excluding the fair value adjustment of our loans and financings. However we are subject to certain financial covenants under the instruments that govern our indebtedness that limit our ability to incur additional debt. The level of our consolidated indebtedness and the requirements and limitations imposed by these debt instruments could adversely affect our financial condition or results of operations. In particular, the terms of some of these debt instruments restrict our ability, and the ability of our subsidiaries, to:

If we are unable to incur additional debt, we may be unable to invest in our business and make necessary or advisable capital expenditures, which could reduce future net operating revenue and adversely affect our profitability. In addition, the cash required to service our indebtedness reduces the amount available to us to make capital expenditures. If we are unable to generate operating cash flows, we may not be able to continue servicing our debt.

Under the RJ Plan, until the fifth anniversary of the Brazilian Confirmation Date, we are required to apply an amount equivalent to 100% of the net revenue from our sale of assets in excess of US$200 million to investments in our activities. Beginning on the sixth anniversary of the Brazilian Confirmation Date, we are required to allocate to the repayment of debt instruments representing recoveries under the RJ Plan on an annual basis an amount equivalent to 70% of the amount by which (1) our cash and cash equivalents and financial investments at the end of each fiscal year exceeds (2) the greater of (a) 25% of our operating expenses and capital expenses for that fiscal year, and (b) R$5,000 million, subject to adjustment in the event that we conclude any capital increases. The cash required to make these repayments will reduce the amount available to us to make capital expenditures.

If we are unable to meet our debt service obligations or comply with our debt covenants, we could be forced to renegotiate or refinance our indebtedness or seek additional equity capital. In this circumstance, we may be unable to obtain financing on satisfactory terms, or at all.

For more information regarding the debt instruments to which we are obligated, see “Management’s Discussion and Analysis of Financial Condition and Results of Operation—Indebtedness” and “—Prepetition Liabilities Subject to Compromise.”

We rely on strategic suppliers of equipment, materials and certain services necessary for our operations and expansion. If these suppliers fail to provide equipment, materials or services to us on a timely basis, we could experience disruptions, which could have an adverse effect on our revenues and results of operations.

We rely on a few strategic suppliers of equipment and materials, including Huawei and Nokia Solutions and Networks do Brasil Telecomunicações Ltda, to provide us with equipment and materials that we need in order to expand and to operate our business in Brazil. In addition, we rely on a third-party provider of network maintenance services in certain regions were we operate. There are a limited number of suppliers with the capability of providing the mobile network equipment and fixed-line network platforms that our operations and expansion plans require or the services that we require to maintain our networks. In addition, because the supply of mobile network equipment and fixed-line network platforms requires detailed supply planning and this equipment is technologically complex, it would be difficult for our company to replace the suppliers of this equipment. Suppliers of cables that we need to extend and maintain our networks may suffer capacity constraints or difficulties in obtaining the raw materials required to manufacture these cables. As a result, we are exposed to risks associated with these suppliers, including restrictions of production capacity for equipment and materials, availability of equipment and materials, delays in delivery of equipment, materials or services, and price increases. If these suppliers or vendors fail to provide equipment, materials or services to us on a timely basis or otherwise in compliance with the terms of our contracts with these suppliers, we could experience disruptions or declines in the quality of our services, which could have an adverse effect on our revenues and results of operations, and we might be unable to satisfy the requirements contained in our concession and authorization agreements.

We are subject to numerous legal and administrative proceedings, which could adversely affect our business, results of operations and financial condition.

We are subject to numerous legal and administrative proceedings. It is difficult to quantify the potential impact of these legal and administrative proceedings. We classify our risk of loss from legal and administrative proceedings as “probable,” “possible” or “remote.” We make provisions for probable losses but do not make provisions for possible and remote losses.

As a result of the RJ Proceedings, we have applied ASC 852 in preparing our consolidated financial statements. ASC 852 requires that financial statements separately disclose and distinguish transactions and events that are directly associated with our reorganization from the transactions and events that are associated with the ongoing operations of our business. Accordingly, our prepetition obligations, including certain of our legal contingencies, that may be impacted by the RJ Proceedings based on our assessment of these obligations following the guidance of ASC 852 have been classified on our balance sheet as “Liabilities subject to compromise.” Prepetition liabilities subject to compromise are required to be reported at the amount allowed as a claim by the RJ Court, regardless of whether they may be settled for lesser amounts and remain subject to future adjustments based on negotiated settlements with claimants, actions of the RJ Court or other events. As of June 30, 2018 and December 31, 2017, the aggregate amount of legal contingencies recognized by the RJ Court was R$4,329 million and R$13,162 million, respectively. For more information about the impact of the RJ Proceedings on our legal proceedings, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Prepetition Liabilities Subject to Compromise—Labor Contingencies,” “—Civil Contingencies – ANATEL,” and “—Civil Contingencies – Other Claims, “Business—Our Judicial Reorganization Proceedings—Implementation of the Judicial Reorganization Plan,” note 28 to our audited consolidated financial statements included in this prospectus and note 19 to our unaudited interim consolidated financial statements included in this prospectus.

In addition, as of June 30, 2018 and December 31, 2017, the total estimated amount in controversy for those proceedings not subject to the RJ Plan in respect of which the risk of loss was deemed probable or possible totaled approximately R$28,162 million and R$27,603 million, respectively, and we had established provisions of R$1,304 million and R$1,368 million, respectively, relating to these proceedings. Our provisions for legal contingencies are subject to monthly monetary adjustments. For a detailed description of our provisions for contingencies, see note 18 to our audited consolidated financial statements included in this prospectus and note 19 to our unaudited interim consolidated financial statements included in this prospectus.

We are not required to disclose or record provisions for proceedings in which our management judges the risk of loss to be remote. However, the amounts involved in certain of the proceedings in which we believe our risk of loss is remote could be substantial. Consequently, our losses could be significantly higher than the amounts for which we have recorded provisions.

If we are subject to unfavorable decisions in any legal or administrative proceedings and the losses in those proceedings significantly exceed the amount for which we have provisioned or involve proceedings for which we have made no provision, our results of operations and financial condition may be materially adversely affected. Even for the amounts recorded as provisions for probable losses, a judgment against us would have an effect on our cash flow if we are required to pay those amounts. Unfavorable decisions in these legal proceedings may, therefore, reduce our liquidity and adversely affect our business, financial condition and results of operations. For a more detailed description of these proceedings, see “Business—Legal Proceedings”.

We have indemnification obligations with respect to the PT Exchange and the PT Portugal Disposition that could materially adversely affect our financial position.

In the exchange agreement, or the PT Exchange Agreement, that we entered into with Pharol under which we transferred defaulted commercial paper of Rio Forte Investments S.A., or Rio Forte, to Pharol in exchange for the delivery to our company of Common Shares and Preferred Shares as described under “Principal Shareholders—PT Option Agreement,” we agreed to indemnify Pharol against any loss arising from (1) Pharol’s contingent or absolute tax or anti-trust obligations in relation to the assets contributed to our company in the Oi capital increase in connection with which we acquired PT Portugal from Pharol in May 2014 and (2) Pharol’s management activities, with reference to acts or triggering events occurring on or prior to May 5, 2014, excluding any losses incurred by Pharol as a result of the financial investments in the Rio Forte commercial paper and the acquisition of the Rio Forte commercial paper from Oi under the PT Exchange Agreement.

In the PTP Share Purchase Agreement under which we sold PT Portugal in the PT Portugal Disposition, we agreed to indemnify Altice Portugal for breaches of our representations and warranties under the PTP Share Purchase Agreement, subject to certain customary procedural and financial limitations. There can be no assurance that we will not be subject to significant claims under these indemnification provisions and if we are subject to such claims under these indemnification provisions, we could be required to pay significant amounts, which would have an adverse effect on our financial condition.

We are subject to potential liabilities relating to our third-party service providers, which could have a material adverse effect on our business, financial condition and results of operations.

We are subject to potential liabilities relating to our third-party service providers in Brazil. Such potential liabilities may involve claims by employees of third-party service providers in Brazil directly against us as if we were the direct employer of such employees, as well as claims against us for secondary liability for, among other things, occupational hazards, wage parity or overtime pay, in the event that such third-party service providers fail to meet their obligations to their employees. We have not recorded any provisions for such claims, and significant judgments against us could have a material adverse effect on our business, financial condition and results of operations.

We are subject to delinquencies of our accounts receivables. If we are unable to limit payment delinquencies by our customers, or if delinquent payments by our customers increase, our financial condition and results of operations could be adversely affected.

Our business significantly depends on our customers’ ability to pay their bills and comply with their obligations to us. During the six-month period ended June 30, 2018, we recorded provisions for doubtful accounts in the amount of R$781 million, or 7.0% of our net operating revenue, primarily due to subscribers’ delinquencies. During 2017, we recorded provisions for doubtful accounts in the amount of R$692 million, or 2.9% of our net operating revenue, primarily due to subscribers’ delinquencies. As of June 30, 2018 and December 31, 2017, our provision for doubtful accounts was R$1,781 million and R$1,342 million, respectively.

ANATEL regulations prevent us from implementing certain policies that could have the effect of reducing delinquency of our customers in Brazil, such as service restrictions or limitations on the types of services provided based on a subscriber’s credit record. If we are unable to successfully implement policies to limit delinquencies of our Brazilian subscribers or otherwise select our customers based on their credit records, persistent subscriber delinquencies and bad debt will continue to adversely affect our operating and financial results.

In addition, if the Brazilian economy declines due to, among other factors, a reduction in the level of economic activity, an increase in inflation or an increase in domestic interest rates, a greater portion of our customers may not be able to pay their bills on a timely basis, which would increase our provision for doubtful accounts and adversely affect our financial condition and results of operations.

We are dependent on key personnel and the ability to hire and retain additional personnel.

We believe that our success will depend on the continued services of our senior management team and other key personnel. Our management team is comprised of highly qualified professionals, with extensive experience in the telecommunications industry. The loss of the services of any of our senior management team or other key employees could adversely affect our business, financial condition and results of operations. We also depend on the ability of our senior management and key personnel to work effectively as a team.

Our future success also depends on our ability to identify, attract, hire, train, retain and motivate highly skilled technical, managerial, sales and marketing personnel. Competition for such personnel is intense, and we cannot guarantee that we will successfully attract, assimilate or retain a sufficient number of qualified personnel. Failure to retain and attract the necessary technical, managerial, sales and marketing and administrative personnel could adversely affect our business, financial condition and results of operations.

Risks Relating to Our Brazilian Operations

Our Residential Services business faces competition from mobile services and other fixed-line service providers, which may adversely affect our revenues and margins.

Our Residential Services business, which provides local and long-distance fixed-line voice, fixed-line data, or broadband, and subscription television, or Pay-TV, services to our residential customers, as well as bundles of these services together with mobile services, faces competition from:

37

Table of Contents

Based on information available from ANATEL, from December 31, 2012 to June 30, 2018, the number of fixed lines in service (including the number fixed lines provided to our Business-to-Business, or B2B, customers) in our service areas (all of Brazil other than the state of São Paulo) declined from 27.7 million to 25.1 million . As of June 30, 2018, based on information available from ANATEL, (1) we had a market share of 53.2% of the total fixed lines in service in Region I of Brazil and a market share of 48.9% of the total fixed lines in service in Region II of Brazil (in each case, including the fixed lines provided to our B2B customers); (2) Claro had a market share of 24.8% of the total fixed lines in service in Region I and a market share of 20.1% of the total fixed lines in service in Region II; and (3) Telefônica Brasil had a market share of 14.1% of the total fixed lines in service in Region I and a market share of 25.9% of the total fixed lines in service in Region II.

As a result of competition from mobile services, we expect (1) the number of our fixed lines in service to experience a slow decline, as some of our customers eliminate their fixed-line services in favor of mobile services, and (2) the use of existing fixed lines for making voice calls to decline, as customers replace fixed-line calls in favor of calls on mobile phones as a result of the emergence of “all-net” plans, which allow a customer to make calls to any fixed-line or mobile device of any operator for a flat monthly fee. The rate at which the number of fixed lines in service in our service areas, a large majority of which are used by our residential customers, may decline depends on many factors beyond our control, such as economic, social, technological and other developments in Brazil. Despite the recent deceleration of fixed line disconnections, because we derive a significant portion of our net operating revenue from our Residential Services business, the reduction in the number of our fixed lines in service has negatively affected and is likely to continue to negatively affect our net operating revenue and margins.

Our broadband services in Brazil face strong competition from Claro, Telefônica Brasil and small regional players, which had market shares of 24.1%, 16.0% and an aggregate 22.2%, respectively, for broadband services in Regions I and II of Brazil as of June 30, 2018, according to data from ANATEL. As of June 30, 2018, we had a market share of 30.9% for broadband services in Regions I and II of Brazil, according to data from ANATEL. Claro provides local fixed-line services to residential customers through its cable network in the portions of Regions I and II where it provides cable television and broadband services under the “Net” brand. Telefônica Brasil provides local fixed-line services through its own network and the assets it acquired from Vivendi S.A. when it acquired GVT Participações S.A. in 2015. The primary drivers of competition in the broadband industry are speed and price, with discounts typically offered in the form of bundled services. Claro and Telefônica Brasil each offer broadband services at higher speeds than ours and both offer integrated voice, broadband and subscription television services, typically as bundles, to the residential services market through a single network infrastructure. Future offerings by our competitors that are aggressively priced or that offer additional services could have an adverse effect on our net operating revenue and our results of operations.

The primary providers of Pay-TV services in the regions in which we provide residential services are SKY, which provides direct-to-home, or DTH, service, and Claro, which provides DTH service under the “Claro TV” brand and Pay-TV services using coaxial cable under the “Net” brand. We offer DTH services throughout the regions in which we provide residential services. Future changes in satellite technology may result in one of our competitors utilizing new satellites for DTH services that have higher capacities or better quality of service, which could adversely affect our net operating revenue and may adversely affect our results of operations.

Our primary competitors for residential services, Claro and Telefônica Brasil, are each controlled by multinational companies that may have more significant financial and marketing resources, and greater abilities to access capital on a timely basis and on more favorable terms, than our company. In addition, we compete in our service areas with smaller companies that have been authorized by ANATEL to provide local fixed-line services. Increased competition from these small, regional companies may require us to increase our marketing expenses and our capital expenditures, which would lead to a decrease in our profitability. For a more information about our competition in the residential services market in Brazil, see “Business—Competition—Residential Services”.

Our Personal Mobility Services business faces strong competition from fixed-line service providers other mobile services providers and internet data providers, which may adversely affect our revenues and margins.

The mobile services market in Brazil is extremely competitive. Our Personal Mobility Services business, which provides post-paid and pre-paid mobile voice services and post-paid and pre-paid mobile data communications services, faces competition from large competitors such as (1) TIM Participações S.A., or TIM, (2) Claro and (3) Telefônica Brasil, which markets its mobile services under the brand name “Vivo.” As of June 30, 2018, based on information regarding the total number of subscribers as of that date available from ANATEL, we had a market share of 16.5% of the total number of mobile subscribers (including subscribers in our B2B Services business), ranking behind Telefônica Brasil with 32.0%, Claro with 25.1% and TIM with 24.1%. Telefônica Brasil, Claro and TIM are each controlled by multinational companies that may have more significant financial and marketing resources, and greater abilities to access capital on a timely basis and on more favorable terms, than our company.

Our ability to generate revenues from our Personal Mobility Services business depends on our ability to continue to maintain or increase the average revenue per unit, or ARPU, generated by our customer base, retain or increase the size of our customer base, improve the perception of the quality of our services and encourage the migration of our customers to our UMTS (Universal Mobile Telecommunications System), or 3G, and our LTE (Long Term Evolution), or 4G, networks through our offers of attractive data packages that take advantage of the structural shift from voice to data usage. The recent trend towards SIM card consolidation, reversing the trend of customers using multiple SIM cards to participate in on-net calling plans and the demand for more aggressive data packages in the pre-paid market may result in a decline in the size of our customer base. The increased use of instant internet messaging and Voice over Internet Protocol, or VoIP, services on smartphone applications such as WhatsApp may result in a migration from voice to data services, which could have an adverse effect on the size and profitability of our customer base. Acquiring each additional personal mobility customer entails costs, including sales commissions and marketing costs. Recovering these costs depends on our ability to retain such customers. Therefore, high rates of customer churn could have a material adverse effect on the profitability of our Personal Mobility Services business. During the six-month period ended June 30, 2018 and the year ended December 31, 2017, the average monthly churn rate of our Personal Mobility Services business was 3.9% and 4.1% per month, respectively.

We have experienced increased pressure to reduce our mobile rates in response to pricing competition. This pricing competition has taken the form unlimited voice plans or special promotional packages, which may include, among other things, traffic usage promotions. We no longer offer handset subsidies for new customers, and competing with the service plans and promotions offered by our competitors may cause an increase in our marketing expenses and customer-acquisition costs, which has adversely affected our results of operations during some periods in the past and could continue to adversely affect our results of operations. Our inability to compete effectively with these packages could result in our loss of market share and adversely affect our net operating revenue and profitability. For more information about our competition in the personal mobility services market in Brazil, see “Business—Competition—Personal Mobility Services”.

Our B2B Services business faces strong competition from other mobile, fixed-line and information technology services providers, which may adversely affect our revenues and margins.

Our B2B Services business provides a la carte and bundled fixed-line voice and data services, mobile voice and data services and information technology services to our small- and medium-sized enterprise, or SME, customers and our corporate (including government) customers, as well as interconnection, network usage and traffic transportation services to other telecommunications providers, which we refer to as our wholesale business. The competition risks relating to the fixed-line and mobile services we provide to our SME and corporate customers are similar to those relating to the fixed-line and mobile services we provide to our residential and personal mobility customers, respectively.

The Brazilian recession has had a significant negative effect on our operating revenue and margins as SMEs generally, including our customers, have reduced the size of their businesses and in some cases ceased operations, and a number of our Corporate customers have reduced their telecommunications spending as part of their overall cost-cutting efforts. Because we derive a significant portion of our net operating revenue from our B2B Services business, the loss of a significant number of SME and corporate customers would adversely affect our net operating revenue and may adversely affect our results of operations. For more information about our competition in the B2B market in Brazil, see “Business—Operations in Brazil—Competition—B2B Services”.

Our long-distance services in Brazil face significant competition, which may adversely affect our revenues.

In Brazil, unlike in the United States and elsewhere, a caller chooses its preferred long-distance carrier for each long-distance call, whether originated from a fixed-line telephone or a mobile handset, by dialing such carrier’s long-distance carrier selection code ( Código de Seleção de Prestadora ). The long-distance services market in Brazil has become less competitive as a result of ongoing reductions in the interconnection rates, as mandated by ANATEL. The proliferation of all-net service plans, particularly for mobile services, offers unlimited long-distance calls and data combination plans that have reduced the relevance of long-distance services for mobile services. As a result, competition for long-distance services in Brazil is limited to fixed-line voice services. We compete with Telefônica Brasil, which is the incumbent fixed-line service provider in the State of São Paulo. Competition in the Brazilian fixed-line long-distance market may require us to increase our marketing expenses and/or provide services at lower rates than those we currently expect to charge for such services. Competition in the Brazilian fixed-line long-distance market has had and could continue to have a material adverse effect on our revenues and margins.

The Brazilian telecommunications industry is highly regulated. Changes to these regulations have and may continue to adversely impact our business.

The Brazilian telecommunications industry is highly regulated by ANATEL. ANATEL regulates, among other things, rates, quality of service and universal service goals, as well as competition among telecommunications service providers. Changes in laws and regulations, grants of new concessions, authorizations or licenses or the imposition of additional universal service obligations, among other factors, may adversely affect our business, financial condition and results of operations. For more information, see “Business—Regulation of the Brazilian Telecommunications Industry”.

For example, in November 2012, ANATEL approved the General Plan on Competition Targets ( Plano Geral de Metas de Competição ), which includes criteria for the evaluation of telecommunications providers to determine which providers have significant market power, regulations applicable to the wholesale markets for trunk lines, backhaul, access to internet backbone and interconnection services, and regulations related to partial unbundling and/or full unbundling of the local fixed-line networks of public regime service providers. For more information, see “Business—Regulation of the Brazilian Telecommunications Industry—Other Regulatory Matters—General Plan on Competition Targets”. We have been classified by ANATEL as a company with significant market power in certain markets, as a result of which we are subject to increased regulation in areas such as fixed-line and mobile infrastructure sharing and mobile interconnection rates. In 2014 ANATEL approved rules under which interconnection rates we are able to charge for the use of our mobile networks would be reduced between 2016 and 2019. As a result, the mobile interconnection rates for Regions I, II and III declined by 47.1%, 47.7% and 39.2%, respectively, in each of February 2017 and 2018, and they will decline by the same percentages in February 2019. ANATEL has also set the interconnections rates we are able to charge for the use of our fixed-line networks, which have declined between 20.9% and 57.3% in each of February 2017 and 2018 and will continue to decline by the same percentages in February 2019. For more information, see “Business—Rates—Network Usage (Interconnection) Rates”. These regulations have had and will continue to have adverse effects on our revenues, although as a result of reductions in our costs and expenses for these services that we acquire from other telecommunications providers, we cannot predict with certainty the effects that these regulations will have on our results of operations.

In December 2016, legislation was introduced in the Brazilian Congress, which we refer to as PLC 79, to substantially amend certain features of the current regulatory framework of the Brazilian telecommunications industry. For more information about PLC 79, see “Business—Regulation of the Brazilian Telecommunications Industry—Concessions and Authorizations—Other Regulatory Matters—New Regulatory Framework”. PLC 79 has faced political gridlock in the Brazilian Congress and has not yet been passed, and we cannot predict whether this legislation will ultimately be adopted by the Brazilian Congress and executed by the President or will be adopted as proposed. Furthermore, should this legislation be adopted, many of its provisions would only have effects on our business following a rule-making procedure by ANATEL to implement the modifications to the regulatory scheme. We cannot predict the form of these new regulations or the time required for ANATEL to propose or adopt these regulations. Therefore, we are unable to predict with any certainty the effects of this legislation on our company, if adopted.

We cannot predict whether ANATEL, the Brazilian Ministry of Science Technology, Innovation and Communication ( Ministério da Ciência, Tecnologia, Inovação e Comunicação ), or the Brazilian Ministry of Communication, or the Brazilian government will adopt these or other telecommunications sector policies in the future or the consequences of such policies on our business or the business of our competitors. In the event that any modification of the regulatory scheme or new regulations applicable to our company are adopted that increase the costs of compliance to our company, whether through capital expenditure requirements, increased service requirements, increased costs for renewal of our authorizations and licenses, increased exposure to regulatory penalties or otherwise, these modifications and regulations could have a material adverse effect on our business, financial condition and results of operations.

Our local fixed-line and domestic long-distance concession agreements in Brazil are subject to periodic modifications by ANATEL and we cannot assure you that the modifications to these concession agreements will not have adverse effects on our company.

We provide fixed-line telecommunications services in our Brazilian service areas pursuant to concession agreements with the Brazilian government. These concession agreements expire on December 31, 2025, and may be amended by the parties every five years prior to the expiration date. In connection with each five-year amendment, ANATEL has the right, following public consultations, to impose new terms and conditions in response to changes in technology, competition in the marketplace and domestic and international economic conditions.

Table of Contents

Our obligations under our concession agreements may be subject to revision in connection with each future amendment. Our concession agreements were last amended in 2011. In 2014, ANATEL held a public comment period for the 2015 revision of the terms of our concession agreements and met regularly with us throughout 2015 to discuss possible amendments, and in 2016 the Brazilian Ministry of Communication issued an ordinance addressing guidelines for the establishment of a new regulatory framework for telecommunications, in line with the provisions of PLC 79. Despite these efforts, our concession agreements have not yet been amended, as a result of the Brazilian Congress’s failure to date to pass PLC 79, passage of which is required to provide the necessary legal authority for ANATEL to implement the proposed changes to our concession agreements. Further discussions regarding amendments to our concession agreements have halted pending resolution of PLC 79. Under their existing terms, our concession agreements may be amended by December 2020 at the latest. If PLC 79 is not passed, our concession agreements will expire in 2025 without the possibility of renewal. For more information about our concession agreements, see “Business—Concessions, Authorizations and Licenses—Fixed-Line and Domestic Long-Distance Services Concession Agreements”.

In connection with the consideration of revisions to the concession agreements under the public regime, in January 2017, ANATEL proposed revisions to the terms of the General Plan of Grants ( Plano Geral de Outorgas ), in line with the provisions of PLC 79. However, as a result of the legislative gridlock faced by PLC 79, ANATEL has halted implementation of the General Plan of Grants. For more information about PLC 79 and ANATEL’s proposed revisions to the terms of the General Plan of Grants, see “Business—Regulation of the Brazilian Telecommunications Industry—Other Regulatory Matters—New Regulatory Framework”.

We cannot assure you that any future amendments to our concession agreements or the General Plan of Grants will not impose requirements on our company that will require us to undertake significant capital expenditures or will not modify the rate-setting procedures applicable to us in a manner that will significantly reduce the net operating revenue that we generate from our Brazilian fixed-line businesses. If the amendments to our Brazilian concession agreements have these effects, our business, financial condition and results of operations could be materially adversely affected.

Our local fixed-line and domestic long-distance concession agreements expire on December 31, 2025 and we cannot assure you that our bids for new concessions upon the expiration of our existing concessions will be successful or that the pending expiration of these concessions will not have adverse effects on our ability to finance our operations.

Our concession agreements will expire on December 31, 2025. We expect the Brazilian government to offer new concessions in competitive auctions prior to the expiration of our existing concession agreements. We may participate in such auctions, but our existing fixed-line and domestic long-distance concession agreements will not entitle us to preferential treatment in these auctions. If we do not secure concessions for our existing service areas in any future auctions, or if such concessions are on less favorable terms than our current concessions, our business, financial condition and results of operations would be materially adversely affected. In addition, based on the current scheduled expiration of our concession agreements and the uncertainty that the terms of these concessions will be extended, investors may be unwilling to make investments in our company on terms that are attractive to our company, or at all. Our inability to raise capital in the equity or debt markets on favorable terms, or at all, could have a materially adverse effect on our business, financial condition and results of operations.

Our local fixed-line and domestic long-distance concession agreements in Brazil, as well as our authorizations to provide personal mobile services in Brazil, contain certain obligations, and our failure to comply with these obligations may result in various fines and penalties being imposed on us by ANATEL.

Our local fixed-line and domestic long-distance concession agreements in Brazil contain terms reflecting the General Plan of Universal Service Goals, the General Plan of Quality Goals ( Plano Geral de Metas de Qualidade ) and other regulations adopted by ANATEL, the terms of which could affect our financial condition and results of operations. Our local fixed-line concession agreements in Brazil also require us to meet certain network expansion, quality of service and modernization obligations in each of the Brazilian states in our service areas. In the event of noncompliance with ANATEL targets in any one of these states, ANATEL can establish a deadline for achieving the targeted level of such service, impose penalties and, in extreme situations, terminate the applicable concession agreement for noncompliance with our quality and universal service obligations. See “Business—Regulation of the Brazilian Telecommunications Industry—Regulation of Fixed-Line Services”.

In addition, our authorizations to provide personal mobile services contain certain obligations requiring us to meet network scope and quality of service targets. If we fail to meet these obligations, we may be fined by ANATEL until we are in full compliance with our obligations and, in extreme circumstances, our authorizations could be revoked by ANATEL. See “Business—Regulation of the Brazilian Telecommunications Industry—Regulation of Mobile Services—Obligations of Personal Mobile Services Providers”.

On an almost weekly basis, we receive inquiries from ANATEL requiring information from us on our compliance with the various service obligations imposed on us by our concession agreements. If we are unable to respond satisfactorily to those inquiries or comply with our service obligations under our concession agreements, ANATEL may commence administrative proceedings in connection with such noncompliance. We have received numerous notices of commencement of administrative proceedings from ANATEL, mostly due to our inability to achieve certain targets established in the General Plan on Quality Goals and the General Plan of Universal Service Goals.

At the time that ANATEL notifies us it believes that we have failed to comply with our obligations, we evaluate the claim and, based on our assessment of the probability of loss relating to that claim, may establish a provision. We vigorously contest a substantial number of the assessments made against us. As a result of the commencement of the RJ Proceedings, our contingencies related to claims of ANATEL were reclassified liabilities subject to compromise and were measure as required by ASC 852. As of June 30, 2018 and December 31, 2017, our prepetition liabilities subject to compromise included R$928 million and R$9,334 million, respectively, related with claims of ANATEL. For more information relating to the reclassification of contingencies related to claims of ANATEL as of June 30, 2018, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Principal Factors Affecting Our Financial Condition and Results of Operations—Effects of the RJ Proceedings and Our Financial Restructuring.”

By operation of the RJ Plan and the Brazilian Confirmation Order (provided that the Brazilian Confirmation Order is not overturned or altered as a result of the pending appeals filed against it), the claim for these contingent obligations has been novated and discharged under Brazilian law and ANATEL is entitled only to receive the recovery set forth in the RJ Plan in exchange for these contingent claims in accordance with the terms and conditions of the RJ Plan. For more information regarding the recoveries to which ANATEL is entitled under the RJ Plan, see “Business—Our Judicial Reorganization Proceedings—Implementation of the Judicial Reorganization Plan—Settlement of Class III Claims—ANATEL.”

We may be unable to implement our plans to expand and enhance our existing networks in Brazil in a timely manner or without unanticipated costs, which could hinder or prevent the successful implementation of our business plan and result in revenues and net income being less than expected.

Our ability to achieve our strategic objectives depends in large part on the successful, timely and cost-effective implementation of our plans to expand and enhance our networks in Brazil. Factors that could affect this implementation include:

Although we believe that our cost estimates and implementation schedule are reasonable, we cannot assure you that the actual costs or time required to complete the implementation of these projects will not substantially exceed our current estimates. Any significant cost overrun or delay could hinder or prevent the successful implementation of our business plan and result in revenues and net income being less than expected.

Certain key inputs are subject to risks related to importation, and we acquire other key inputs from a limited number of domestic suppliers, which may further limit our ability to acquire such inputs in a timely and cost effective manner.

The high growth in data markets in general and broadband in particular may result in a limited supply of equipment essential for the provision of such services, such as data transmission equipment and modems. The restrictions on the number of manufacturers imposed by the Brazilian government for certain inputs, mainly data transmission equipment and modems, and the geographical locations of non-Brazilian manufacturers of these inputs, pose certain risks, including:

If any of these risks materialize, they may result in our inability to provide services to our customers in a timely manner or may affect the prices of our services, which may have an adverse effect on our business, financial condition and results of operations.

We make investments based on demand forecasts that may become inaccurate due to economic volatility and may result in revenues that lower than expected.

We make certain investments, such as the procurement of materials and the development of physical sites, based on our forecasts of the amount of demand that customers will have for our services at a later date (generally several months later). However, any major changes in the Brazilian economic scenario may affect this demand and therefore our forecasts may turn out to be inaccurate. For example, economic crises may restrict credit to the population, and uncertainties relating to employment may result in a delay in the decision to acquire new products or services. As a result, it is possible that we may make larger investments based on demand forecasts than were necessary given actual demand at the relevant time, which may directly affect our cash flow.

Furthermore, improvements in economic conditions may have the opposite effect. For example, an increase in demand not accompanied by our investment in improved infrastructure may result in a possible loss of opportunity to increase our revenue or result in the degradation of the quality of our services.

We may be unable to respond to the recent trend towards consolidation in the Brazilian telecommunications market.

The Brazilian telecommunications market has been subject to consolidation. Mergers and acquisitions may change market dynamics, create competitive pressures, force small competitors to find partners and impact our financial condition; and may require us to adjust our operations, marketing strategies (including promotions), and product portfolio. For example, in March 2015, Telefónica S.A. acquired from Vivendi S.A., all of the shares of GVT Participações S.A., the controlling shareholder of Global Village Telecom S.A. This acquisition increased Telefónica’s share of the Brazilian telecommunications market, and we believe such trend is likely to continue in the industry as players continue to consolidate. Additional joint ventures, mergers and acquisitions among telecommunications service providers are possible in the future. If such consolidation occurs, it may result in increased competition within our market. We may be unable to adequately respond to pricing pressures resulting from consolidation in our market, adversely affecting our business, financial condition and results of operations. We may also consider engaging in merger or acquisition activity in response to changes in the competitive environment, which could divert resources away from other aspects of our business.

Companies in the Brazilian telecommunication industry, including us, may be harmed by restrictions regarding the installation of new antennas for mobile services.

Currently, there are approximately 250 municipal laws in Brazil that limit the installation of new antennas for mobile service, which has been a barrier to the expansion of mobile networks. Those laws are meant to regulate issues related to zoning and the alleged effects of the radiation and radiofrequencies of the antennas. The federal law, that establishes new guidelines to create a consolidated plan for the installation of antennas was approved in 2015, however, it is still pending specific regulation. Despite the federal initiative, as long as the municipal laws remain unchanged, the risk of noncompliance with regulations and of having services of limited quality in certain areas continues to exist, which could materially and adversely affect our business, results of operations and financial condition.

Additional antenna installation is also limited as a result of concerns that radio frequency emissions from base stations may cause health problems. See “—General Risks Relating to the Telecommunications Industry—The mobile telecommunications industry and participants in this industry, including us, may be required to adopt an extensive program of field measurements of radio frequency emissions and be subject to further regulation and/or claims based on concerns regarding potential health problems and interfere with medical devices”.

Our commitment to meet the obligations of our Brazilian employees’ pension plans, managed by Fundação Sistel de Seguridade Social and Fundação Atlântico de Seguridade Social may be higher than what is currently anticipated, and therefore, we may be required to make additional contributions of resources to these pension plans or to record liabilities or expenses that are higher than currently recorded.

As sponsors of certain private employee pension plans in Brazil, which are managed by Fundação Sistel de Seguridade Social, or Sistel, and Fundação Atlântico de Seguridade Social, or FATL, our subsidiaries cover the actuarial deficits of these pension benefit plans, which provide guaranteed benefits to our retirees in Brazil and guaranteed future benefits to our current Brazilian employees at the time of their retirement. As of December 31, 2017, our Brazilian pension benefit plans had an aggregate deficit of R$632 million. Our commitment to meet these deficit obligations may be higher than we currently anticipate, and we may be required to make additional contributions or record liabilities or expenses that are higher than we currently record, which may adversely affect our financial results. If the life expectancy of the beneficiaries should exceed the life expectancies included in the actuarial models, the level of our contributions to these plans could increase. If the managers of these plans should suffer losses on the investments of the assets of these plans, we would be required to make additional contributions to these plans in order for these plans to be able to provide the agreed benefits. Any increase in the level of our contributions to these plans as a result of an increase in life expectancy or a decline in investment returns could have a material adverse effect on our financial condition or results of operations. For a more detailed description of our Brazilian pension plans, see “Business—Employees—Employee Benefits—Pension Benefit Plans.”

As a result of the RJ Proceedings, certain of our unfunded obligations under our post-retirement plans have been classified on our balance sheet as “Liabilities subject to compromise.” As of December 31, 2017, the aggregate amount of our unfunded obligations under our post-retirement defined benefit plans recognized by the RJ Court was R$560 million, all of which related to claims of FATL. As of June 30, 2018, these claims had been novated. As of June 30, 2018, we had reclassified R$560 million on our balance sheet as “liability for pension benefits, net of provision for unfunded status on our balance sheet.” For more information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations —Prepetition Liabilities Subject to Compromise,” “Business—Employees—Employee Benefits—Pension Benefit Plans—Fundação Atlântico de Seguridade Social—BrTPREV Plan,” note 28 to each of our audited consolidated financial statements included in this prospectus and our unaudited interim consolidated financial statements included in this prospectus.

Risks Relating to Our African and Asian Operations

Any impairment of the fair market value at which we record our indirect investment in Unitel in our financial statements would have a material adverse effect on our financial condition and results of operations.

As of June 30, 2018 and December 31, 2017, we recorded in our consolidated financial statements as assets held for sale of R$5,082 million and R$4,675 million, respectively, mainly relating to our interest in Unitel, including R$2,345 million and R$2,012 million, respectively, of accrued dividends owed to our company by Unitel and R$2,032 million and R$1,920 million, respectively, representing the fair market value of Africatel’s 25% interest in Unitel, and recorded as liabilities directly associated with assets held for sale of R$274 million and R$354 million, respectively, mainly relating to our interest in Unitel.

The book value of our indirect investment in Unitel is subjected to testing for impairment when events or changes in circumstances indicate that the value of our indirect investment in Unitel may be lower than the fair market value at which we carry this investment. We recorded losses of R$190 million and R$267 million for the six-month period ended June 30, 2018 and the year ended December 31, 2017, respectively, as a result of our review of the fair value of our investment in Unitel. Any further impairment of our indirect investment in Unitel may result in a material adverse effect on our financial condition and results of operations.

We cannot assure you as to when PT Ventures will realize the accounts receivable recorded with respect to the declared and unpaid dividends owed to PT Ventures by Unitel or when PT Ventures will receive dividends that have been declared or that may be declared by Unitel in the future.

Since November 2012, PT Ventures has not received any payments for outstanding amounts owed to it by Unitel with respect to dividends declared by Unitel for the fiscal years ended December 31, 2014, 2013, 2012 and 2011, and the extraordinary dividends declared by Unitel in November 2010 based on its 2005 results of operations and free reserves held in 2006 through 2009. Based on the dividends declared by Unitel for those fiscal years, PT Ventures has an estimated recoverable amount of US$608.3 million (R$2,355.5 million) as of December 31, 2017. The gross amount of unpaid dividends by Unitel to PT Ventures refers to US$122.5 million (R$472.3 million) with respect to fiscal year 2014, US$190.0 million (R$732.6 million) with respect to fiscal year 2013, US$190.0 million (R$732.6 million) with respect to fiscal year 2012, US$190.0 million (R$732.6 million) with respect to fiscal year 2011, and US$93.9 million (R$362.1 million) with respect to the dividends declared in 2010. As of the date of this prospectus, PT Ventures has not received any such amounts.

In addition, at a general meeting of the shareholders of Unitel held on May 13, 2015, the other shareholders discussed the financial statements as well as the payment of dividends with respect to fiscal year 2014. The other Unitel shareholders did not permit PT Ventures to attend and participate in this shareholders’ meeting alleging that they did not acknowledge PT Ventures as a Unitel shareholder. PT Ventures has received a copy of the minutes of this meeting, which indicate that Unitel declared dividends in the amount of US$490.0 million (R$1,889.3 million), of which PT Ventures’ share amounts to US$122.5 million (R$472.3 million).

On June 12, 2015, PT Ventures filed a suit in the Provincial Courts of Luanda requesting the court to require Unitel to produce the final minutes of the May 13, 2015 general shareholders’ meeting and to annul all resolutions purportedly made at this meeting. Unitel filed its defense and a motion to dismiss this action on November 23, 2015, and PT Ventures filed its answer to Unitel’s motion on December 7, 2015. A preparatory hearing took place before the Civil and Administrative Division of the Luanda Provincial Court on May 30, 2016, in order to allow the parties to try and reach an immediate agreement. However, both parties reiterated their respective positions during the hearing and no settlement agreement was reached. On April 5, 2017, the court rendered its decision and voided all the resolutions taken during the May 13, 2015 Unitel General Meeting. At a general meeting of the shareholders of Unitel held on August 16, 2017, the other shareholders reapproved all the resolutions that had been declared null and void by the Angolan court, with the dissenting vote of PT Ventures.

At a general meeting of the shareholders of Unitel held on July 26, 2017, the other shareholders of Unitel approved the allocation of the 2015 profits to free reserve and retained earnings accounts, with the dissenting vote of PT Ventures.

On August 16, 2017, a general meeting of shareholders of Unitel was convened to resolve upon the allocation of the 2016 profits, among other issues. The management proposed not to pay any dividends to shareholders again. However, PT Ventures’ representative at the meeting claimed that, since the management proposal had not been disclosed to the shareholders in advance, the shareholders had not had the opportunity to properly assess the proposal and therefore any resolution about the subject would end up being null and void.

On May 29, 2018, a general meeting of shareholders was convened and the discussions of some of the pending items in the agenda of the general meeting of August 16, 2017 resumed, including the allocation of the 2016 profits, as well as to resolve upon the financial statements for the fiscal year ended December 31, 2017 and the allocation of the 2017 profits, among other issues. Unitel’s management once again proposed not to pay any dividends to shareholders. The other shareholders of Unitel approved the allocation of the 2016 profits to free reserve and retained earnings accounts, with the dissenting vote of PT Ventures.

Table of Contents

On June 27, 2018, a general meeting of shareholders of Unitel was convened to resolve upon the allocation of the 2017 profits, among other issues. The management proposed not to pay any dividends to shareholders again. The Unitel shareholders agreed that 50% of the profit, i.e., 43,311,227,624 Angolan Kwanza, should be distributed to the shareholders.

On several occasions, PT Ventures has requested an explanation from Unitel about its failure to pay to PT Ventures its share of the declared dividends. As of the date of this prospectus, PT Ventures has not received a satisfactory explanation regarding this failure to pay, nor has PT Ventures received reliable indications as to the expected timing of the payment of the accrued dividends. As a result, on October 20, 2015, PT Ventures filed a suit in the Provincial Courts of Luanda seeking payment of outstanding dividends for the fiscal years 2010 through 2013, together with interest thereon. As a result of our institution of this suit, in 2017 and 2016 we recognized provisions with respect to the unpaid dividends of US$45 million (R$174 million) and US$14 million (R$54 million), respectively.

We cannot assure you that PT Ventures will be successful in these suits, as to the timing of the payment of the accrued dividends to our company, or whether we will be able to receive dividends that have been declared or that may be declared by Unitel in the future. Our inability to receive these dividends could have a material adverse impact on the fair value of our investment in Unitel, our financial position and our results of operations.

The other shareholders of Unitel have claimed that they believe that Pharol’s sale of a minority interest in Africatel to our company did not comply with the Unitel shareholders’ agreement.

The Unitel shareholders’ agreement provides a right of first refusal to the other shareholders of Unitel if any shareholder desires to transfer any or all of its shares of Unitel, other than transfers to certain affiliated companies. This agreement also provides that if any shareholder breaches a material obligation under the Unitel shareholders’ agreement, the other shareholders will have a right to purchase the breaching shareholder’s stake in Unitel at its net asset value.

On March 14, 2016, the other shareholders of Unitel initiated an arbitration proceeding against PT Ventures, claiming that Pharol’s sale of a minority interest in Africatel to our company did not comply with the Unitel shareholders’ agreement. The other shareholders of Unitel had previously made the same claim as a counterclaim in the arbitration initiated by PT Ventures on October 13, 2015, but then withdrew that counterclaim. The arbitral tribunal was constituted on April 14, 2016. On May 19, 2016, the arbitration proceeding against PT Ventures initiated by the other shareholders of Unitel was consolidated with the arbitration initiated by PT Ventures on October 13, 2015. PT Ventures presented its statement of claim on October 14, 2016 and the other shareholders of Unitel presented their statement of defense and counterclaim on February 28, 2017. A hearing in the arbitration was held from February 7 to 16, 2018, where each party presented its arguments and the factual witnesses and experts from each side were heard. We cannot predict the outcome of this proceeding. An adverse outcome in this proceeding could have a material adverse impact on our financial condition and results of operations.

PT Ventures disputes the other shareholders’ interpretation of the relevant provisions of the Unitel shareholders’ agreement, and we believe that the relevant provisions of the Unitel shareholders’ agreement apply only to a transfer of Unitel shares by PT Ventures itself. We have been defending against the allegation by Unitel’s other shareholders vigorously. If a binding decision by the arbitral tribunal were rendered ruling in favor of the interpretation of the Unitel shareholders’ agreement proposed by the other Unitel shareholders, PT Ventures could be required to sell its interest in Unitel for a value significantly lower than the amount that we record in our financial statements with respect to our indirect investment in Unitel. The sale of PT Ventures’ interest in Unitel in these circumstances could have a material adverse impact on our financial condition and results of operations.

The other shareholders of Unitel have prevented PT Ventures from exercising its rights to appoint the chief executive officer and a majority of the board of directors of Unitel.

Under the Unitel shareholders’ agreement, PT Ventures is entitled to appoint three of the five members of Unitel’s board of directors and its chief executive officer. Under the Unitel shareholders’ agreement, the appointment of the chief executive officer of Unitel is subject to the approval of the holders of 75% of Unitel’s shares. However, the other shareholders of Unitel have failed to vote to elect the directors nominated by PT Ventures at Unitel’s shareholders’ meetings, and as a result, PT Ventures’ representation on Unitel’s board of directors was reduced.

On July 22, 2014, the only member of Unitel’s board of directors that had been appointed by PT Ventures resigned from his position, and the other shareholders of Unitel have not permitted PT Ventures to appoint a replacement. In November 2014, the other shareholders of Unitel stated to PT Ventures that its rights as a shareholder of Unitel had been purportedly “suspended” in October 2012, although these other shareholders have not indicated any legal basis for this alleged suspension. At a general shareholders’ meeting of Unitel held on December 15, 2014, an election of members of the board of directors of Unitel was held. At this meeting, Unitel’s other shareholders claimed that PT Ventures was not entitled to vote as a result of the alleged suspension of its rights as a shareholder of Unitel in October 2012, and they refused to elect the member nominated by PT Ventures to Unitel’s board of directors. As of the date of this prospectus, no nominee of PT Ventures serves on the Unitel board of directors.

On January 14, 2015, PT Ventures filed a suit in the Provincial Court of Luanda to annul all resolutions purportedly taken during the December 15, 2014 general shareholders’ meeting of Unitel. PT Ventures was notified of the terms of Unitel’s defense on August 20, 2018 and submitted its reply on August 28, 2018. Some of the challenged deliberations became moot on December 15, 2015 because they had not been implemented within one year of their adoption.

On October 13, 2015, PT Ventures initiated an arbitration proceeding against the other shareholders of Unitel as a result of the violation by those shareholders of a variety of provisions of the Unitel shareholders’ agreement, including the provisions entitling PT Ventures to nominate the majority of the members of the board of directors of Unitel and its chief executive officer. The arbitral tribunal was constituted on April 14, 2016. PT Ventures presented its statement of claim on October 14, 2016 and the other shareholders of Unitel presented their statement of defense and counterclaim on February 28, 2017. A hearing in the arbitration was held from February 7 to 16, 2018, where each party presented its arguments and the factual witnesses and experts from each side were heard. A closing hearing was held on May 9, 2018. The parties exchanged their first post-hearing briefs on July 13, 2018. We cannot predict the outcome of this proceeding. An adverse outcome in this proceeding could have a material adverse impact on our financial condition and results of operations. For more information about this proceeding, see “Business—Legal Proceedings—Legal Proceedings Relating to Our Interest in Unitel.”

Unitel has called a general shareholders’ meeting to be held on October 18, 2018, with the express purpose of electing the new members of the company’s corporate bodies, including the board of directors. PT Ventures has provided Unitel with the names of three candidates for the board of directors, one of whom should also be appointed as the managing director.

Unitel has granted loans to a related party and entered into a management contract with a third-party without the approval of PT Ventures.

Under the Unitel shareholders’ agreement, the shareholders of Unitel and their affiliates are not permitted to enter into any contracts with Unitel unless the contracts are approved by a resolution of Unitel’s board of directors adopted by at least four members of its board of directors. As a result of the inability of PT Ventures to appoint members of the Unitel board of directors, PT Ventures is unable to effectively exercise its implied veto right over related party transactions of Unitel.

Between May 2012 and August 2013, Unitel made disbursements to Unitel International Holdings B.V., or Unitel Holdings, of €322.9 million and US$43.0 million under various facility agreements entered into between Unitel and Unitel Holdings. Unitel Holdings is owned by Mrs. Isabel dos Santos, an indirect shareholder of Unitel and a member of the board of directors of Unitel.

In September 2015, PT Ventures commenced litigation in the British Virgin Islands, or the BVI, against Vidatel, one of the other shareholders of Unitel, seeking a worldwide freezing order against Vidatel (prohibiting Vidatel from disposing of, dealing or diminishing the value of any of its assets (whether in the BVI or elsewhere)). In February 2016, the BVI court issued a judgment granting this freezing order against Vidatel pending the conclusion of the ICC arbitration brought by PT Ventures. In March 2018, the BVI court denied an application by Vidatel to set aside the worldwide freezing order. Vidatel appealed that decision, and the court of appeal rejected Vidatel’s appeal on April 4, 2018.

In March 2016, PT Ventures commenced litigation in the Netherlands against Unitel Holdings, Isabel dos Santos, Tokeyna Management Limited and Unitel’s chief executive officer as defendants, claiming that each of the defendants cooperated with and/or benefited from the misappropriation of funds from Unitel. The defendants in the Dutch litigation challenged the jurisdiction of the court, and in May 2017 the Dutch District Court denied the defendants’ objection and affirmed jurisdiction. A hearing took place before the Dutch Court of Appeal on May 25, 2018. On August 14, 2018, the Dutch Court of Appeal upheld the Dutch District Court’s judgement in its entirety.

We cannot assure you that we will be able to prevent Unitel from taking actions that should require the approval of the members of the Unitel board of directors nominated by PT Ventures, including approving related party transactions with the other shareholders of Unitel that we believe are detrimental to the financial condition and results of operations of Unitel. The use of the resources of Unitel in this manner could have a material adverse impact on the financial position and results of operations of Unitel and therefore the value of our investment in Unitel.

On October 13, 2015, PT Ventures initiated an arbitration proceeding against the other shareholders of Unitel as a result of the violation by those shareholders of a variety of provisions of the Unitel shareholders’ agreement, including the provisions that would have entitled PT Ventures to veto these related party transactions. The arbitral tribunal was constituted on April 14, 2016. PT Ventures presented its statement of claim on October 14, 2016 and the other shareholders of Unitel presented their statement of defense and counterclaim on February 28, 2017. A hearing in the arbitration was held from February 7 to 16, 2018, where each party presented its arguments and the factual witnesses and experts from each side were heard. A closing hearing was held on May 9, 2018. The parties exchanged their first post-hearing briefs on July 13, 2018.We cannot predict the outcome of this proceeding. An adverse outcome in this proceeding could have a material adverse impact on our financial condition and results of operations. For more information about this proceeding, see “Business—Legal Proceedings—Legal Proceedings Relating to Our Interest in Unitel.”

The other shareholders of Unitel have attempted to dilute our indirect ownership of Unitel through a capital increase in which we could be technically unable to participate, and have called shareholders’ meetings at which they have indicated the desire to unilaterally amend the by-laws of Unitel and the Unitel shareholders’ agreement.

At a general shareholders’ meeting of Unitel held on December 15, 2014, the other shareholders of Unitel voted to increase Unitel’s share capital and alter the nominal value of its shares. The details of this capital increase are obscure to us as they were not included in the prior notice for this meeting nor were they discussed in detail during this meeting. Additional details of this capital increase have been included in draft minutes of this meeting provided to PT Ventures and it appears that, although PT Ventures has determined to subscribe to its pro rata share of this capital increase to avoid dilution of its interest in Unitel, payment of the subscription price may be proposed under conditions that would not permit PT Ventures to obtain the necessary foreign exchange approvals prior to the date on which payment would be due.

The agenda of this general shareholders’ meeting of Unitel included amendments to Unitel’s by-laws and purported amendments to Unitel shareholders’ agreement, in addition to other matters that may have been raised at the shareholders’ meeting itself, which included investments by Unitel in Zimbabwe and a study in order to implement a corporate reorganization of Unitel. We have not been provided of the details of the proposed by-law amendments nor of any purported amendments to the Unitel shareholders’ agreement. The December 15, 2014 meeting was suspended without any action taken on these items.

On January 14, 2015, PT Ventures filed a suit in the Provincial Court of Luanda to annul all resolutions purportedly taken during the December 15, 2014 general shareholders’ meeting of Unitel, including the approval of the Unitel capital increase, the approval of investments by Unitel in Zimbabwe, and a study in order to implement a corporate reorganization of Unitel. PT Ventures was notified of the terms of Unitel’s defense on August 20, 2018 and submitted its reply on August 28, 2018. Some of the challenged deliberations became moot on December 15, 2015 because they had not been implemented within one year of their adoption.

We note that there appears to be no legal authority for the other shareholders of Unitel to amend the Unitel shareholders’ agreement through actions taken at a general meeting of shareholders, as this agreement is an agreement among the parties thereto. Should the other shareholders approve actions detrimental to Unitel or our investment in Unitel, these actions could have a material adverse impact on the financial position and results of operations of Unitel and therefore the value of our investment in Unitel.

Adverse political, economic and legal conditions in the African and Asian countries in which we have acquired investments may hinder our ability to receive dividends from our African and Asian subsidiaries and investments.

The governments of many of the African and Asian countries in which we have investments have historically exercised, and continue to exercise, significant influence over their respective economies and legal systems. Countries in which we have investments may enact legal or regulatory measures that restrict the ability of our subsidiaries and investees to make dividend payments to us. Similarly, adverse political or economic conditions in these countries may hinder our ability to receive dividends from our subsidiaries and investees. Historically, Pharol has received dividends from the African and Asian subsidiaries and investees that we have acquired; however, a limitation on our ability to receive a material portion of those dividends could adversely affect our cash flows and liquidity.

In addition, our investments in these regions are exposed to political and economic risks that include, but are not limited to, exchange rate and interest rate fluctuations, inflation and restrictive economic policies and regulatory risks that include, but are not limited to, the process for the renewal of licenses and the evolution of regulated retail and wholesale tariffs. In addition, our ventures in African and Asian markets face risks associated with increasing competition, including due to the entrance of new competitors and the rapid development of new technologies.

The development of partnerships in these markets raises risks related to the ability of the partners to jointly operate the assets. Any inability of our company and our partners to operate these assets may have a negative impact on our strategy and all of these risks may have material effects on our results of operations.

Risks Relating to Brazil

The Brazilian government has exercised, and continues to exercise, significant influence over the Brazilian economy. This involvement, as well as Brazilian political and economic conditions, could adversely impact our business, results of operations and financial condition.

Oi is a Brazilian corporation, and a majority of our operations and customers are located in Brazil. Accordingly, our financial condition and results of operations are substantially dependent on Brazil’s economy. The Brazilian government frequently intervenes in the Brazilian economy and occasionally makes significant changes in policy and regulations. The Brazilian government’s actions to control inflation and implement macroeconomic policies have often involved increases in interest rates, wage and price controls, currency devaluations, blocking access to bank accounts, imposing capital controls and limits on imports, among other things. We do not have any control over, and are unable to predict, which measures or policies the Brazilian government may adopt in the future. Our business, results of operations and financial condition may be adversely affected by changes in policies or regulations, or by other factors such as:

Uncertainty over whether possible changes in policies or rules affecting these or other factors may contribute to economic uncertainties in Brazil and to heightened volatility in the Brazilian securities markets and securities issued abroad by Brazilian issuers. The President of Brazil has considerable power to determine governmental policies and actions that relate to the Brazilian economy and, consequently, affect the operations and financial performance of businesses such as our company. We can offer no assurances that the policies that may be implemented by the Brazilian federal or state governments will not adversely affect our business, results of operations and financial condition.

52

Table of Contents

In addition, protests, strikes and corruption scandals have led to a fall in confidence and a political crisis. For example, Brazilian markets have been experiencing heightened volatility due to the uncertainties derived from the ongoing “Lava Jato” investigation, which is being conducted by the Office of the Brazilian Federal Prosecutor, and its impact on the Brazilian economy and political environment. Members of the Brazilian federal government and of the legislative branch, as well as senior officers of certain Brazilian private and state-owned companies, have faced allegations of political corruption. These government officials and senior officers allegedly accepted bribes by means of kickbacks on contracts granted by major state-owned companies to several infrastructure, oil and gas and construction companies. The profits of these kickbacks allegedly financed the political campaigns of the main political parties in Brazil that were unaccounted for or not publicly disclosed, as well as served to personally enrich the recipients of the bribery scheme. As a result of the ongoing “Lava Jato” investigation, a number of senior politicians, including congressman and officers of the major state-owned companies in Brazil resigned or have been arrested. The potential outcome of the “Lava Jato” investigation is uncertain, but it has already adversely affected the Brazilian markets and trading prices of securities issued by Brazilian issuers. We cannot predict whether the “Lava Jato” investigation will lead to further political and economic instability or whether new allegations against government officials or other companies in Brazil will arise in the future.

Moreover, on December 2, 2015, the Brazilian Congress opened impeachment proceedings against Brazilian President Dilma Rousseff for allegedly breaking federal budget laws during her re-election campaign in 2014. On May 12, 2016, the Brazilian Senate voted to begin its review of the impeachment proceedings against President Dilma Rousseff, who was suspended from office. After the legal and administrative process for the impeachment, Brazil’s Senate removed President Dilma Rousseff from office on August 31, 2016 for infringing budgetary laws. Michel Temer, the former vice president, who had been acting President of Brazil following Ms. Rousseff’s suspension in May 2016, was sworn in by Senate to serve out the remainder of the presidential term until 2018. There was an ongoing proceeding before the Brazilian Higher Electoral Court ( Tribunal Superior Eleitoral ) alleging that the electoral alliance between Ms. Rousseff and Mr. Temer in the 2014 general election had violated campaign finance laws. On June 9, 2017, the Brazilian Higher Electoral Court absolved the electoral alliance, including President Temer of wrongdoing; however, he remains subject to heightened scrutiny due to the ongoing Lava Jato investigations. The resolution of the political and economic crisis in Brazil still depends on the outcome of the Lava Jato investigation and proceedings and approval of reforms that are expected to be promoted by the new president. In addition, the presidential election in Brazil is expected to occur in October 2018. The election may change government political policies and the elected administration may implement new policies. We cannot predict which policies the Brazilian government may adopt or change or the effect that any such policies might have on our business and on the Brazilian economy. Any such new policies or changes to current policies may have a material adverse effect on our business, results of operations and financial condition.

Furthermore, political demonstrations in Brazil over the last few years have affected the development of the Brazilian economy and investors’ perceptions of Brazil. For example, street protests, which started in mid-2013 and continued through 2016, demonstrated the public’s dissatisfaction with the worsening Brazilian economic condition (including an increase in inflation and fuel prices as well as rising unemployment), the perception of widespread corruption, as well as the potential for severe water and electricity rationing following a decrease in rainfall and water reservoir levels throughout Brazil in early 2016. In addition, in May 2018, a nationwide truckers’ strike in which truck drivers, dissatisfied by the increase in fuel prices, blocked roads throughout the country, preventing the delivery of goods and gasoline to Brazilian businesses, resulted in a general slowdown in commercial transactions during the strike.

Depreciation of the real may lead to substantial losses on our liabilities denominated in or indexed to foreign currencies.

During the four decades prior to 1999, the Brazilian Central Bank periodically devalued the Brazilian currency. Throughout this period, the Brazilian government implemented various economic plans and used various exchange rate policies, including sudden devaluations (such as daily and monthly adjustments), exchange controls, dual exchange rate markets and a floating exchange rate system. Since 1999, exchange rates have been set by the market. The exchange rate between the real and the U.S. dollar has varied significantly in recent years. For example, the real /U.S. dollar exchange rate increased from R$1.9554 per U.S. dollar on December 31, 2000 to R$3.5333 on December 31, 2002. The real depreciated by 8.9% against the U.S. dollar during 2012, by 14.6% during 2013, by 13.4% during 2014 and by 47.1% during 2015, appreciated by 16.5% in 2016 and depreciated by 1.5% in 2017. In addition, the real depreciated by 10.7% against the Euro during 2012, by 19.7% during 2013, was substantially unchanged during 2014, depreciated by 31.7% in 2015, appreciated by 19.1% in 2016 and depreciated by 15.4% in 2017 and 13.0% in the six-month period ended June 30, 2018.

As of June 30, 2018 and December 31, 2017, R$31,070 million and R$36,557 million, respectively, of our loans and financing classified as liabilities subject to compromise was denominated in currencies other than the real , representing 61.4% and 74.4%, respectively, of our consolidated financial indebtedness. As a result of the commencement of the RJ Proceedings, we ceased recording exchange rate gains and losses with respect to these loans and financings. Following the implementation of the RJ Plan, our obligations under (1) our New Notes that were issued to holders of bonds issued by Oi, Oi Coop and PTIF that are entitled to receive the Qualified Recovery described under “Business—Our Judicial Reorganization Proceedings—Implementation of the Judicial Reorganization Plan— Settlement of Class III Claims – Defaulted Bonds—Qualified Recovery,” (2) participations under the Non-Qualified Credit Agreement that was available to holders of bonds issued by Oi, Oi Coop and PTIF that were entitled to receive the Non-Qualified Recovery described under “Business—Our Judicial Reorganization Proceedings—Implementation of the Judicial Reorganization Plan—Settlement of Class III Claims – Defaulted Bonds—Non-Qualified Recovery,” (3) recoveries of creditors under our export credit agreements described under “Business—Our Judicial Reorganization Proceedings—Implementation of the Judicial Reorganization Plan—Settlement of Class III Claims – Export Credit Agreements,” and (4) recoveries under our bonds issued by Oi, Oi Coop and PTIF to holders of our U.S. dollar-denominated bonds issued by Oi and Oi Coop that are not entitled to receive the Qualified Recovery or the Non-Qualified Recovery, as described under “Business—Our Judicial Reorganization Proceedings—Implementation of the Judicial Reorganization Plan—Settlement of Class III and Class IV Claims – Default Recovery,” will be denominated in U.S. dollars and will accrue interest at fixed-rates in U.S. dollars.

As of June 30, 2018, R$6,268 million of our loans and financing not classified as liabilities subject to compromise was denominated in currencies other than the real , representing 12.4% of our consolidated financial indebtedness.

When the real depreciates against foreign currencies, we incur losses on our liabilities denominated in or indexed to foreign currencies, such as our U.S. dollar-denominated and Euro-denominated long-term debt and foreign currency loans, and we incur gains on our monetary assets denominated in or indexed to foreign currencies, as the liabilities and assets are translated into reais . If significant depreciation of the real were to occur when the value of such liabilities significantly exceeds the value of such assets, including any financial instruments entered into for hedging purposes, we could incur significant losses, even if the value of those assets and liabilities has not changed in their original currency. In addition, a significant depreciation in the real could adversely affect our ability to meet certain of our payment obligations. A failure to meet certain of our payment obligations could trigger a default under certain financial covenants in our debt instruments, which could have a material adverse effect on our business and results of operations. During 2016, in connection with our consideration of potential plans to restructure our indebtedness, we did not roll over our non-deliverable forwards and settled our long-term currency swaps. As a result, our exposure to foreign currency fluctuations has increased substantially. As an effect of the approval and confirmation of the RJ Plan, we expect to restructure our indebtedness in a manner that the increased exposure to foreign currency fluctuations to be temporary. In the event that these expectations are not met, the effects of foreign currency fluctuations on our debt instruments could have a material adverse effect on our financial condition and results of operations.

A portion of our capital expenditures and operating leases require us to acquire assets or use third-party assets at prices denominated in or linked to foreign currencies, some of which are financed by liabilities denominated in foreign currencies, principally the U.S. dollar and the Euro. We generally do not hedge exposures relating to our capital expenditures or operating expenses against risks related to movements of the real against foreign currencies. To the extent that the value of the real decreases relative to the U.S. dollar or the Euro, it becomes more costly for us to purchase these assets or services, which could adversely affect our business and financial performance.

Depreciation of the real relative to the U.S. dollar could create additional inflationary pressures in Brazil by increasing the price of imported products and requiring recessionary government policies, including tighter monetary policy. On the other hand, appreciation of the real against the U.S. dollar may lead to a deterioration of the country’s current account and balance of payments, as well as to a dampening of export-driven growth.

If Brazil experiences substantial inflation in the future, our margins and our ability to access foreign financial markets may be reduced. Government measures to curb inflation may have adverse effects on the Brazilian economy, the Brazilian securities market and our business and results of operations.

Brazil has in the past experienced extremely high rates of inflation, with annual rates of inflation reaching as high as 2,708% in 1993 and 1,093% in 1994. Inflation and some of the Brazilian government’s measures taken in an attempt to curb inflation have had significant negative effects on the Brazilian economy.

Since the introduction of the real in 1994, Brazil’s inflation rate has been substantially lower than in previous periods. However, actions taken in an effort to control inflation, coupled with speculation about possible future governmental actions, have contributed to economic uncertainty in Brazil and heightened volatility in the Brazilian securities market. More recently, Brazil’s rates of inflation, as measured by the General Market Price Index — Internal Availability ( Índice Geral de Preços — Disponibilidade Interna ), or IGP-DI, published by Fundação Getúlio Vargas, or FGV, were 5.5% in 2013, 3.8% in 2014, 10.7% in 2015, 7.2% in 2016, (0.42)% in 2017 and 5.5% in the six-month period ended June 30, 2018. According to the Broad Consumer Price Index ( Índice Nacional de Preços ao Consumidor Ampliado ), or IPCA, published by the Brazilian Institute for Geography and Statistics ( Instituto Brasileiro de Geografia e Estatística ), or IBGE, the Brazilian consumer price inflation rates were 5.9% in 2013, 6.4% in 2014, 10.7% in 2015, 6.3% in 2016, 2.9% in 2017 and 2.6% in the six-month period ended June 30, 2018.

If Brazil experiences substantial inflation in the future, our costs may increase and our operating and net margins may decrease. Although ANATEL regulations provide for annual price increases for most of our services in Brazil, such increases are linked to inflation indices, discounted by increases in our productivity. During periods of rapid increases in inflation, the price increases for our services may not be sufficient to cover our additional costs and we may be adversely affected by the lag in time between the incurrence of increased costs and the receipt of revenues resulting from the annual price increases. Inflationary pressures may also curtail our ability to access foreign financial markets and may lead to further government intervention in the economy, including the introduction of government policies that may adversely affect the overall performance of the Brazilian economy.

Fluctuations in interest rates could increase the cost of servicing our debt and negatively affect our overall financial performance.

Our financial expenses are affected by changes in the interest rates that apply to our floating rate debt. As of June 30, 2018 and December 31, 2017, we had, among other consolidated debt obligations, R$11,891 million and R$15,870 million, respectively, of loans and financings that were subject to variable interest rates, including: (1) R$0 million and R$4,982 million, respectively, of loans and financings that were subject to the London Interbank Offered Rate, or LIBOR; (2) R$8,428 million and R$6,388 million, respectively, of loans and financings and debentures that were subject to the Interbank Certificate of Deposit (Certificado de Depósito Interbancário), or CDI, rate, an interbank rate; (3) R$3,463 million and R$2,927 million, respectively, of loans and financings and debentures that were subject to the Long-Term Interest Rate (Taxa de Juros de Longo Prazo), or TJLP, a long-term interest rate; and (4) R$0 million and R$1,573 million, respectively, of loans and financings that were subject to the IPCA rate, an inflation index.

The TJLP includes an inflation factor and is determined quarterly by the National Monetary Council ( Conselho Monetário Nacional ). In particular, the TJLP and the CDI rate have fluctuated significantly in the past in response to the expansion or contraction of the Brazilian economy, inflation, Brazilian government policies and other factors. For example, the CDI increased from 9.77% per annum as of December 31, 2013 to 11.57% per annum as of December 31, 2014, increased to 14.13% per annum as of December 31, 2015, decreased to 13.63% per annum as of December 31, 2016, decreased to 6.89% per annum as of December 31, 2017 and decreased to 6.56% per annum as of June 30, 2018.

As a result of the commencement of the RJ Proceedings, we ceased recording interest expenses on these loans and financings. By operation of the RJ Plan and the Brazilian Confirmation Order (provided that the Brazilian Confirmation Order is not overturned or altered as a result of the pending appeals filed against it), these loans and loans and financings have been novated and discharged under Brazilian law and creditors under these loans and financings are entitled only to receive the recoveries set forth in the RJ Plan in exchange for their claims in accordance with the terms and conditions of the RJ Plan. For more information regarding the recoveries to which creditors under our loans and financings are entitled and received under the RJ Plan, see “Business—Our Judicial Reorganization Proceedings—Implementation of the Judicial Reorganization Plan.”

Following the implementation of the RJ Plan, we expect that recoveries of creditors under our debentures, unsecured lines of credit and lessors under the lease contracts of Oi and Telemar relating to real property owned by Copart 4 and Copart 5 will accrue interest based on the CDI rate. As a result, following the implementation of the RJ Plan, inflation will increase our interest expenses and debt service obligations with respect to these recoveries. In addition, the RJ Plan permits us to seek to raise up to R$2.5 billion in the capital markets and seek to borrow up to R$2 billion under new export credit facilities, as described under “—Liquidity and Capital Resources.” This debt may accrue interest at floating rates in foreign currencies. Accordingly, we may incur interest expenses and foreign exchange gains and losses in connection with this new debt. A significant increase in any of these interest rates could adversely affect our financial expenses and negatively affect our overall financial performance.

The market value of securities issued by Brazilian companies is influenced by the perception of risk in Brazil and other countries, which may have a negative effect on the trading price of Common Shares and Common ADSs and may restrict our access to international capital markets.

Economic and market conditions in other countries and regions, including the United States, the European Union and emerging market countries, may affect to varying degrees the market value of securities of Brazilian issuers. Although economic conditions in these countries and regions may differ significantly from economic conditions in Brazil, investors’ reactions to developments in these other countries may have an adverse effect on the market value of securities of Brazilian issuers, the availability of credit in Brazil and the amount of foreign investment in Brazil. Crises in the European Union, the United States and emerging market countries have at times resulted in significant outflows of funds from Brazil and may diminish investor interest in securities of Brazilian issuers, including our company. This could materially and adversely affect the market price of our securities, and could also make it more difficult for us to access the capital markets and finance our operations in the future on acceptable terms or at all.

Restrictions on the movement of capital out of Brazil may impair our ability to service certain debt obligations.

Brazilian law provides that whenever there exists, or there is a serious risk of, a material imbalance in Brazil’s balance of payments, the Brazilian government may impose restrictions for a limited period of time on the remittance to foreign investors of the proceeds of their investments in Brazil as well as on the conversion of the real into foreign currencies. The Brazilian government imposed such a restriction on remittances for approximately six months in 1989 and early 1990. The Brazilian government may in the future restrict companies from paying amounts denominated in foreign currency or require that any such payment be made in reais . Many factors could affect the likelihood of the Brazilian government imposing such exchange control restrictions, including the extent of Brazil’s foreign currency reserves, the availability of sufficient foreign exchange on the date a payment is due, the size of Brazil’s debt service burden relative to the economy as a whole, and political constraints to which Brazil may be subject. There can be no certainty that the Brazilian government will not take such measures in the future.

A more restrictive policy could increase the cost of servicing, and thereby reduce our ability to pay, our foreign currency-denominated debt obligations and other liabilities. As of June 30, 2018 and December 31, 2017, our foreign-currency denominated debt was R$37,338 million and R$36,557 million, respectively, and represented 73.8% and 74.4%, respectively, of our consolidated indebtedness. If we fail to make payments under any of these restructured debt obligations, we will be in default under those obligations, which could reduce our liquidity as well as the market price of Common Shares and Common ADSs.

In addition, a more restrictive policy could hinder or prevent the Brazilian custodian of Common Shares underlying Common ADSs or holders who have exchanged Common ADSs for the underlying Common Shares from converting dividends, distributions or the proceeds from any sale of such shares into U.S. dollars and remitting such U.S. dollars abroad. In such an event, the Brazilian custodian for the Common Shares will hold the reais that it cannot convert for the account of holders of Common ADSs who have not been paid. Neither the custodian nor the ADS Depositary will be required to invest the reais or be liable for any interest.

Risks Relating to the Common Shares and the Common ADSs

Holders of Common Shares or Common ADSs may not receive any dividends or interest on shareholders’ equity.

According to Oi’s by-laws and the Brazilian Corporate Law, Oi must generally pay its shareholders at least 25% of Oi’s consolidated annual net income as dividends or interest on shareholders’ equity, as calculated and adjusted under Brazilian GAAP. This adjusted net income may be capitalized, used to absorb losses or otherwise retained as allowed under Brazilian GAAP and may not be available to be paid as dividends or interest on shareholders’ equity. Holders of Common Shares or Common ADSs may not receive any dividends or interest on shareholders’ equity in any given year due to the dividend preference of Preferred Shares. Additionally, the Brazilian Corporate Law allows a publicly traded company like Oi to suspend the mandatory distribution of dividends in any particular year if Oi’s board of directors informs Oi’s shareholders that such distributions would be inadvisable in view of Oi’s financial condition or cash availability and subject to approval of the general shareholders’ meeting and analysis by the members of Oi’s fiscal council. Under the RJ Plan, Oi and the other RJ Debtors are prohibited from declaring or paying dividends, interest on shareholders’ equity or other forms of return on capital or making any other payment or distribution on or related to their shares (including any payment related to a merger or consolidation) until the sixth anniversary of the date of the Judicial Ratification of the RJ Plan, subject to certain exceptions, as described under “Dividends and Dividend Policy.”

Holders of Common ADSs may find it difficult to exercise their voting rights at Oi’s shareholders’ meetings.

Under Brazilian law, only shareholders registered as such in Oi’s corporate books may attend Oi’s shareholders’ meetings. All Common Shares underlying Common ADSs are registered in the name of the ADS Depositary. Holders or Common ADSs may exercise the voting rights with respect to the Common Shares represented by their Common ADSs only in accordance with the deposit agreement relating to the Common ADSs. There are practical limitations upon the ability of the holders of Common ADSs to exercise their voting rights due to the additional steps involved in communicating with holders of Common ADSs. For example, Oi is required to publish a notice of Oi’s shareholders’ meetings in certain newspapers in Brazil. To the extent that holders of Common Shares are entitled to vote at a shareholders’ meeting, they will be able to exercise their voting rights by attending the meeting in person or voting by proxy. By contrast, holders of Common ADSs may receive notice of a shareholders’ meeting by mail from the ADS Depositary if Oi notifies the ADS Depositary of the shareholders’ meeting and requests the ADS Depositary to inform holders of Common ADS of the shareholders’ meeting. To exercise their voting rights, holders of Common ADS must instruct the ADS Depositary on a timely basis. This noticed voting process will take longer for holders of Common ADS than for holders of Common Shares. If the ADS Depositary fails to receive timely voting instructions for all or part of the Common ADSs, the ADS Depositary will assume that the holders of those Common ADSs are instructing it to give a discretionary proxy to a person designated by us to vote their Common ADSs, except in limited circumstances.

In the circumstances in which holders of Common ADSs have voting rights, they may not receive the voting materials in time to instruct the depositary to vote the Common Shares underlying their Common ADSs. In addition, the ADS Depositary and its agents are not responsible for failing to carry out voting instructions of the holders of Common ADSs or for the manner of carrying out those voting instructions. Accordingly, holders of Common ADSs may not be able to exercise voting rights, and they will have no recourse if the common shares underlying their Common ADSs are not voted as requested.

Holders of Common Shares or Common ADSs in the United States may not be entitled to the same preemptive rights as Brazilian shareholders have, pursuant to Brazilian legislation, in the subscription of shares resulting from capital increases made by us.

Under Brazilian law, if Oi issues new shares in exchange for cash or assets as part of a capital increase, subject to certain exceptions, Oi must grant its shareholders preemptive rights at the time of the subscription of shares, corresponding to their respective interest in Oi’s share capital, allowing them to maintain their existing shareholding percentage. Oi may not legally be permitted to allow holders of Common Shares or Common ADSs in the United States to exercise any preemptive rights in any future capital increase unless (1) Oi files a registration statement for an offering of shares resulting from the capital increase with the U.S. Securities and Exchange Commission, or SEC, or (2) the offering of shares resulting from the capital increase qualifies for an exemption from the registration requirements of the Securities Act. At the time of any future capital increase, Oi will evaluate the costs and potential liabilities associated with filing a registration statement for an offering of shares with the SEC and any other factors that Oi considers important in determining whether to file such a registration statement. Oi cannot assure the holders of Common Shares or Common ADSs in the United States that Oi will file a registration statement with the SEC to allow them to participate in any of Oi’s capital increases. As a result, the equity interest of such holders in Oi may be diluted.

If holders of Common ADSs exchange them for Common Shares, they may risk temporarily losing, or being limited in, the ability to remit foreign currency abroad and certain Brazilian tax advantages.

The Brazilian custodian for the Common Shares underlying the Common ADSs must obtain an electronic registration number with the Brazilian Central Bank to allow the ADS Depositary to remit U.S. dollars abroad. Holders of Common ADSs benefit from the electronic certificate of foreign capital registration from the Brazilian Central Bank obtained by the custodian for the ADS Depositary, which permits it to convert dividends and other distributions with respect to the Common Shares into U.S. dollars and remit the proceeds of such conversion abroad. If holders of Common ADSs decide to exchange them for the underlying Common Shares, they will only be entitled to rely on the custodian’s certificate of registration with the Brazilian Central Bank for five business days after the date of the exchange. Thereafter, they will be unable to remit U.S. dollars abroad unless they obtain a new electronic certificate of foreign capital registration in connection with the common shares, which may result in expenses and may cause delays in receiving distributions. See “Exchange Controls.”

Also, if holders of Common ADSs that exchange Common ADSs for Common Shares do not qualify under the foreign investment regulations, they will generally be subject to less favorable tax treatment of dividends and distribution on, and the proceeds from any sale of, Common Shares. See “Exchange Controls” and “Taxation—Certain Brazilian Tax Considerations.”

Holders of Common ADSs may face difficulties in protecting their interests because, as a Brazilian company, Oi is subject to different corporate rules and regulations, and Oi’s shareholders may have fewer and less well-defined rights.

Holders of Common ADSs are not direct shareholders of Oi and are unable to enforce the rights of shareholders under Oi’s by-laws and the Brazilian Corporate Law.

Oi’s corporate affairs are governed by Oi’s by-laws and the Brazilian Corporate Law, which differ from the legal principles that would apply if Oi were incorporated in a jurisdiction in the United States, such as the State of Delaware or New York, or elsewhere outside Brazil. Even if a holder of Common ADSs surrenders its Common ADSs and becomes a direct shareholder, its rights as a holder of Common Shares under the Brazilian Corporate Law to protect its interests relative to actions by Oi’s board of directors may be fewer and less well-defined than under the laws of those other jurisdictions.

Although insider trading and price manipulation are crimes under Brazilian law, the Brazilian securities markets are not as highly regulated and supervised as the U.S. securities markets or the markets in some other jurisdictions. In addition, rules and policies against self-dealing or for preserving shareholder interests may be less well-defined and enforced in Brazil than in the United States and certain other countries, which may put holders of Common Shares and Common ADSs at a potential disadvantage. Corporate disclosures also may be less complete or informative than those of a public company in the United States or in certain other countries.

Oi is exempt from some of the corporate governance requirements of the New York Stock Exchange.

Oi is a foreign private issuer, as defined by the SEC for purposes of the Exchange Act. As a result, for so long as Oi remains a foreign private issuer, Oi will be exempt from, and you will not be provided with the benefits of, some of the corporate governance requirements of The New York Stock Exchange, or the NYSE. Oi is permitted to follow practice in Brazil in lieu of the provisions of the NYSE’s corporate governance rules, except that:

Table of Contents

The standards applicable to Oi are considerably different than the standards applied to U.S. domestic issuers. Although Rule 10A-3 under the Exchange Act generally requires that a listed company have an audit committee of its board of directors composed solely of independent directors, as a foreign private issuer, Oi is relying on a general exemption from this requirement that is available to it as a result of the features of Brazilian law applicable to Oi’s fiscal council. In addition, Oi is not required to, among other things:

Oi intends to rely on some or all of these exemptions. As a result, you will not be provided with the benefits of certain corporate governance requirements of the NYSE.

We could be adversely affected by violations of anti-corruption laws and regulations.

We are required to comply with Brazilian anti-corruption laws and regulations, including Law No. 12,846/2013, or the Brazilian Anti-Corruption Law, as well as anti-corruption laws and regulations in other jurisdictions, including the U.S. Foreign Corrupt Practices Act of 1977, or the FCPA.

The Brazilian Anti-Corruption Law, the FCPA and similar anti-corruption laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to government officials or other persons for the purpose of obtaining or retaining business. Recent years have seen a substantial increase in anti-corruption law enforcement activity, with more frequent and aggressive investigations and enforcement proceedings by both the U.S. Department of Justice and the SEC, increased enforcement activity by non-U.S. regulators, and increases in criminal and civil proceedings brought against companies and individuals. Our policies mandate compliance with these anti-corruption laws. We operate, through our businesses, in countries that are recognized as having governmental and commercial corruption. We cannot assure you that our internal control policies and procedures will protect us from reckless or criminal acts committed by our employees, the employees of any of our businesses, or third party intermediaries. In the event that we believe or have reason to believe that our employees or agents have or may have violated applicable anti-corruption laws, including the FCPA, we may be required to investigate or have outside counsel investigate the relevant facts and circumstances, which can be expensive and require significant time and attention from senior management. Violations of these laws may result in criminal or civil sanctions, inability to do business with existing or future business partners (either as a result of express prohibitions or to avoid the appearance of impropriety), injunctions against future conduct, profit disgorgements, disqualifications from directly or indirectly engaging in certain types of businesses, the loss of business permits or other restrictions which could disrupt our business and have a material adverse effect on our business, financial condition, results of operations or liquidity.

Holders of Common ADSs may face difficulties in serving process on or enforcing judgments against us and other persons.

Oi is organized under the laws of Brazil, and all of the members of Oi’s board of directors, Oi’s executive officers and Oi’s independent registered public accountants reside or are based in Brazil. The vast majority of Oi’s assets and those of these other persons are located in Brazil. As a result, it may not be possible for holders of Common ADSs to effect service of process upon Oi or these other persons within the United States or other jurisdictions outside Brazil or to enforce against Oi or these other persons judgments obtained in the United States or other jurisdictions outside Brazil. In addition, because substantially all of Oi’s assets and all of Oi’s directors and officers reside outside the United States, any judgment obtained in the United States against Oi or any of our directors or officers may not be collectible within the United States. Because judgments of U.S. courts for civil liabilities based upon the U.S. federal securities laws may only be enforced in Brazil if certain conditions are met, holders may face greater difficulties in protecting their interests in the case of actions by us or Oi’s board of directors or executive officers than would shareholders of a U.S. corporation.

Brazilian tax laws may have an adverse impact on the taxes applicable to the disposition of Common Shares and Common ADSs.

According to Law No. 10,833, enacted on December 29, 2003, if a Non-Brazilian Holder disposes of assets located in Brazil, the transaction will be subject to taxation in Brazil, even if such disposition occurs outside Brazil or if such disposition is made to another Non-Brazilian Holder. Accordingly, on the disposition of New Common Shares, which are considered assets located in Brazil, the Non-Brazilian Holder will be subject to income tax on the gains assessed, following the rules described under “Taxation—Certain Brazilian Tax Considerations—Taxation of Gains,” regardless of whether the transactions are conducted in Brazil or abroad and with a Brazilian resident or not. A disposition of Common ADSs between Non-Brazilian Holders, however, involves the disposal of a non-Brazilian asset and in principle is currently not subject to taxation in Brazil. Nevertheless, in the event that the concept of “disposition of assets” is interpreted to include the disposition between Non-Brazilian Holders of assets located outside Brazil, this tax law could result in the imposition of withholding taxes in the event of a disposition of Common ADSs made by Non-Brazilian Holders. Due to the fact that, as of the date of this prospectus, Law No. 10,833/2003 has no judicial guidance as to its application, we are unable to predict whether an interpretation applying such tax laws to dispositions of Common ADSs between Non-Brazilian Holders could ultimately prevail in Brazilian courts. See “Taxation—Certain Brazilian Tax Considerations—Taxation of Gains.”

If Oi is characterized as a passive foreign investment company in any taxable year, certain adverse U.S. federal income tax consequences could apply to a U.S. investor who holds Common Shares or Common ADSs during such year.

Oi will be classified as a PFIC in any taxable year if either: (1) 50% or more of the fair market value of our gross assets (determined on the basis of a quarterly average) for the taxable year produce passive income or are held for the production of passive income, or (2) 75% or more of our gross income for the taxable year is passive income. As a publicly traded foreign corporation Oi intends for this purpose to treat the aggregate fair market value of our gross assets as being equal to the aggregate value of our outstanding stock plus the total amount of our liabilities (“Market Capitalization”) and to treat the excess of the fair market value of our assets over their book value as a nonpassive asset to the extent attributable to our nonpassive income. Based on certain estimates of Oi’s gross income and gross assets, the nature of its business, the size of its investment in certain subsidiaries, and its anticipated Market Capitalization, Oi believes that for its taxable year ended December 31, 2015, Oi was a PFIC for U.S. federal income tax purposes; however, Oi also believes that it was not a PFIC for the taxable years ended December 31, 2016 and December 31, 2017. Nevertheless, because PFIC status is determined annually based on Oi’s income, assets and activities for the entire taxable year, it is not possible to determine whether Oi will be characterized as a PFIC for the taxable year ending December 31, 2018, or for any subsequent year, until after the close of the year. Furthermore, because Oi determines the value of its gross assets based on the Market Capitalization test, a decline in the value of its Common Shares and Preferred Shares may result in Oi becoming a PFIC. Accordingly, there can be no assurance that Oi will not be considered a PFIC for any taxable year.

61

Table of Contents

If Oi is characterized as a PFIC, certain adverse U.S. federal income tax consequences could apply to a U.S. investor who holds Common Shares or Common ADSs during such year with respect to any “excess distribution” received from Oi and any gain from a sale or other disposition of Common Shares or Common ADSs, and U.S. investors also may be subject to additional reporting obligations with respect to Common Shares or Common ADSs. Oi does not intend to provide the information necessary for the U.S. investor to make a qualified electing fund election with respect to Common Shares or Common ADSs. See “Taxation—Certain United States Federal Income Tax Considerations—Taxation of New Shares—PFIC Rules.”

Additionally, U.S. holders of Common Shares or Common ADSs whose holding period for such Shares or ADSs includes any portion of the taxable year ended December 31, 2015 may be subject to the PFIC rules discussed below with respect to any dividends received on, and upon the sale, exchange or other taxable disposition of, their Rights or New Shares received upon exercise of the Rights. See “Taxation—Certain United States Federal Income Tax Considerations—Taxation of New Shares.”

If a United States person is treated as owning at least 10% of Oi’s shares, such holder may be subject to adverse U.S. federal income tax consequences.

If a United States person is treated as owning (directly, indirectly or constructively) at least 10% of the value or voting power of Oi’s shares, such person may be treated as a “United States shareholder” with respect to each “controlled foreign corporation” in our group (if any). If United States shareholders own (or are treated as owning) more than 50% of the value or voting power of Oi’s shares, Oi would (and our non-U.S. subsidiaries could) be treated as controlled foreign corporations. In addition, if our group includes one or more U.S. subsidiaries, certain of our non-U.S. subsidiaries could be treated as controlled foreign corporations (regardless of whether we are treated as a controlled foreign corporation). A United States shareholder of a controlled foreign corporation may be required to report annually and include in its U.S. taxable income its pro rata share of “Subpart F income,” “global intangible low-taxed income” and investments in U.S. property by controlled foreign corporations, regardless of whether we make any distributions. An individual that is a United States shareholder with respect to a controlled foreign corporation generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a United States shareholder that is a U.S. corporation. Failure to comply with these reporting obligations may subject you to significant monetary penalties and may prevent the statute of limitations with respect to your U.S. federal income tax return for the year for which reporting was due from starting. We cannot provide any assurances that we will assist investors in determining whether any of our non-U.S. subsidiaries are treated as a controlled foreign corporation or whether such investor is treated as a United States shareholder with respect to any of such controlled foreign corporations or furnish to any United States shareholders information that may be necessary to comply with the aforementioned reporting and tax paying obligations. Certain of our shareholders may be United States shareholders. The determination of controlled foreign corporation status is complex and includes attribution rules, the application of which is not entirely certain. A United States investor should consult its advisors regarding the potential application of these rules to an investment in Common Shares or Common ADSs.

The relative volatility and illiquidity of the Brazilian securities markets may adversely affect holders of Common Shares and Common ADSs.

The Brazilian securities markets are substantially smaller, less liquid and more volatile than major securities markets in the United States. The B3, which is the principal Brazilian stock exchange, had a market capitalization of R$3.2 trillion (US$955.6 billion) as of December 31, 2017 and an average daily trading volume of R$8.7 billion (US$2.6 billion) for 2017. In comparison, aggregate market capitalization of the companies (including U.S. and non-U.S. companies) listed on the NYSE was US$22.1 trillion as of December 31, 2017 and the NYSE recorded an average daily trading volume of US$58.2 billion for 2017. There is also significant concentration in the Brazilian securities markets. The ten largest companies in terms of market capitalization represented approximately 53% of the aggregate market capitalization of the B3 as of December 31, 2017. The ten most widely traded stocks in terms of trading volume accounted for approximately 39% of all shares traded on the B3 in 2017. These market characteristics may substantially limit the ability of holders of Common ADSs to sell the Common Shares underlying the Common ADSs at a price and at a time when they wish to do so and, as a result, could negatively impact the market price of the Common ADSs themselves.

The imposition of IOF taxes may indirectly influence the price and volatility of Common Shares and Common ADSs.

Brazilian law imposes the Tax on Foreign Exchange Transactions, or the IOF/Exchange Tax, on the conversion of reais into foreign currency and on the conversion of foreign currency into reais . Brazilian law also imposes the Tax on Transactions Involving Bonds and Securities, or the IOF/Securities Tax, due on transactions involving bonds and securities, including those carried out on a Brazilian stock exchange.

In October 2009, the Brazilian government imposed the IOF/Exchange Tax at a rate of 2.0% in connection with inflows of funds related to investments carried out by non-Brazilian investors in the Brazilian financial and capital markets with the objective of slowing the pace of speculative inflows of foreign capital into the Brazilian market and the appreciation of the real against the U.S. dollar. The rate of the IOF/Exchange Tax generally applicable to foreign investments in the Brazilian financial and capital markets was later increased to 6.0%. In December 2011, the rate of the IOF/Exchange Tax applicable to several types of investments was reduced back to zero percent. As of the date of this prospectus, all investments in the Brazilian financial and capital markets are subject to the IOF/Exchange Tax rate of zero percent.

In November 2009, the Brazilian government also established that the rate of the IOF/Securities Tax would apply to the transfer of shares with the specific purpose of enabling the issuance of ADSs. In December 2013, the rate of the IOF/Securities Tax applicable to transactions involving the issuance of ADSs was reduced to zero percent.

The imposition of these taxes may discourage foreign investment in shares of Brazilian companies, including Oi, due to higher transaction costs, and may negatively impact the price and volatility of the Common ADSs and Common Shares on the NYSE and the B3.
