RISK FACTORS

You should carefully consider the risks described below, as well as the other information in this prospectus before deciding to purchase any common shares or ADSs. Our business, results of operations, financial condition or prospects could be materially and adversely affected if any of these risks occurs, and as a result, the market price of our common shares and ADSs could decline and you could lose all or part of your investment. In general, investors take more risk when they invest in the securities of issuers in emerging markets such as Argentina than when they invest in the securities of issuers in the United States and other more developed markets. The risks described below are those known to us and that we currently believe may materially affect us.

Risks Relating to Argentina

Substantially all of our revenues are generated in Argentina and thus are highly dependent on economic and political conditions in Argentina

Central Puerto is an Argentine corporation ( sociedad anónima ). All of our assets and operations are located in Argentina. Accordingly, our financial condition and results of operations depend to a significant extent on macroeconomic, regulatory, social and political conditions prevailing in Argentina, including the level of growth, inflation rates, foreign exchange rates, interest rates and international developments and conditions that may affect Argentina. Between 2007 and 2015, the Fernández de Kirchner administrations increased direct intervention in the Argentine economy, including the implementation of expropriation measures, price controls, exchange controls and changes in laws and regulations affecting foreign trade and investment. These measures had a material adverse effect on private sector entities, including us. It is possible that similar measures could be adopted by the current or future Argentine government or that economic, social and political developments in Argentina, over which we have no control, could have a material adverse effect on the Argentine economy and, in turn, adversely affect our financial condition and results of operations. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting our Results of Operations—Argentine Economic Conditions.”

The Argentine economy remains vulnerable and any significant decline could adversely affect our results of operations

The Argentine economy has experienced significant volatility in recent decades, characterized by periods of low or negative growth, high levels of inflation and currency devaluation. Sustainable economic growth in Argentina is dependent on a variety of factors, including the international demand for Argentine exports, the stability and competitiveness of the peso against foreign currencies, confidence among consumers and foreign and domestic investors, a stable rate of inflation, national employment levels and the circumstances of Argentina’s regional trade partners.

The Argentine economy remains vulnerable, as reflected by the following economic conditions:

36

As in the recent past, Argentina’s economy may be adversely affected if political and social pressures inhibit the implementation by the Argentine government of policies designed to control inflation, generate growth and enhance consumer and investor confidence, or if policies implemented by the Argentine government that are designed to achieve these goals are not successful. These events could materially adversely affect our financial condition and results of operations.

Any decline in economic growth, increased economic instability or expansion of economic policies and measures taken by the Argentine government to control inflation or address other macroeconomic developments that affect private sector entities such as us, all developments over which we have no control, could have an adverse effect on our financial condition or results of operations.

The impact of presidential and congressional elections on the future economic and political environment of Argentina is uncertain, but likely to be material

Presidential and congressional elections in Argentina took place on October 25, 2015, and a runoff election ( ballotage ) between the two leading presidential candidates was held on November 22, 2015, which resulted in Mr. Mauricio Macri being elected President of Argentina. The Macri administration assumed office on December 10, 2015.

On October 22, 2017, mid-term legislative elections were held at the federal and provincial government levels. Macri’s Cambiemos alliance obtained the most votes in the City of Buenos Aires, as well as in the provinces of Buenos Aires, Chaco, Córdoba, Corrientes, Entre Ríos, Jujuy, La Rioja, Mendoza, Neuquén, Salta, Santa Cruz and Santa Fe. As a result, as of December 10, 2017, Cambiemos increased its representation in the Argentine Congress by nine senators (holding in the aggregate 24 of a total of 72 seats in the Senate) and by 21 members of the Chamber of Deputies (holding in the aggregate 107 of a total of 257 seats in such Chamber).

Since assuming office, the Macri administration has announced and implemented several significant economic and policy reforms, including:

37

38

Pursuant to Resolution No. 522/16, the ENRE ordered a public hearing to be held to evaluate the proposals for the full tariff review filed by EDENOR and EDESUR for the period beginning January 1, 2017 to December 31, 2021. The hearing was held on October 28, 2016 and, following such hearing, on January 31, 2017, the ENRE issued Resolution No. 63/17, by virtue of which such administrative authority approved the tariffs to be applied by EDENOR. Similarly, Resolution No. 64/17 approved EDESUR’s tariffs. With regards to transmission tariffs, seven public hearings were held pursuant to Resolutions Nos. 601/16, 602/16, 603/16, 604/16, 605/16, 606/16, 607/16 of the ENRE. In such public hearings the tariff proposals filed by transmission companies Transener S.A, Distrocuyo S.A., Transcomahue S.A., Ente Provincial de Energía de Neuquén, Transba S.A., Transnea S.A., Transnoa S.A., and Transpa S.A. for the period beginning January 1, 2017 to December 31, 2021 were evaluated. Pursuant to Resolutions Nos. 66/17, 68/17, 69/17, 71/17, 73/17, 75/17, 77/17 and 79/17, the ENRE approved the new applicable tariffs of such companies.

The Macri administration does not have a majority of seats in the Argentine Congress and, therefore, it may be difficult to adopt some of those measures unless he obtains support from the opposition, creating uncertainty as to the ability of the Macri administration to pass any measure that it expects to implement. In addition, recent judicial decisions substantially limiting the Macri administration’s efforts to raise tariffs and protests throughout Argentina in respect of such efforts have added to political uncertainty. This political uncertainty in respect of economic measures could lead to volatility in the market prices of securities of Argentine companies.

The fiscal, monetary and currency adjustments undertaken by the Macri administration may subdue growth in the short-term. For example, immediately after the foreign exchange controls were lifted on December 16, 2015, the dismantling of the multiple exchange regime resulted in the official peso exchange rate (available only for certain types of transactions) falling in value by 40.1%, as the peso-U.S. dollar exchange rate reached Ps.13.76 to US$1.00 on December 17, 2015. The Central Bank has since allowed the peso to float with limited intervention intended to ensure the orderly operation of the MULC. On January 17, 2018, the exchange rate was Ps.18.85 to US$1.00, as quoted by the Banco de la Nación Argentina for wire transfers ( divisas ).

As of the date of this prospectus, the impact that these measures and any future measures taken by the current administration will have on the Argentine economy as a whole and the electric power industry in particular cannot be predicted. The proposed economic liberalization could be disruptive to the economy and fail to benefit, or harm, our business. There remains uncertainty as to which additional measures announced during the presidential campaign will be taken by the Macri administration and when these will be implemented, if ever. In particular, we have no control over the implementation of the reforms to the regulatory framework that governs our operations and cannot guarantee that these reforms will be implemented or implemented in a manner that will benefit our business. The failure of these measures to achieve their intended goals could adversely affect the Argentine economy, which, in turn may have an adverse effect on our financial condition and results of operations.

If the current levels of inflation do not decrease, the Argentine economy could be adversely affected

Historically, inflation has materially undermined the Argentine economy and the Argentine government’s ability to create conditions that permit growth. In recent years, Argentina has experienced high inflation rates. See “—The credibility of several Argentine economic indices has been called into question, which has led to a lack of confidence in the Argentine economy and could affect your evaluation of this offering and/or the market value of the ADSs” below.

During 2016, the City of Buenos Aires CPI inflation rate was 41.05%, while according to the Province of San Luis CPI, the inflation rate was 31.53%. The new INDEC IPC inflation rates for January, February, March,

39

April, May, June, July, August and September 2017 were 1.3%, 2.5%, 2.4%, 2.6%, 1.3%, 1.2%, 1.7%, 1.4% and 1.9%, respectively. In the past, and particularly throughout the Fernández de Kirchner administration, the Argentine government has implemented programs to control inflation and monitor prices for essential goods and services, including attempts to freeze the price of certain supermarket products and price support arrangements agreed between the Argentine government and private sector companies in several industries and markets, that did not address the structural causes of inflation and failed to reduce inflation.

High inflation rates affect Argentina’s foreign competitiveness, social and economic inequality, negatively impacts employment, consumption and the level of economic activity and undermines confidence in Argentina’s banking system, which could further limit the availability of and access by local companies to domestic and international credit.

Inflation remains a challenge for Argentina given its persistent nature in recent years. The Argentine government has announced its intention to reduce the primary fiscal deficit as a percentage of GDP over time and also reduce the Argentine government’s reliance on Central Bank financing. If, despite the measures adopted by the Argentine government, these measures fail to address Argentina’s structural inflationary imbalances, the current levels of inflation may continue and have an adverse effect on Argentina’s economy and can also lead to an increase in Argentina’s debt. Moreover, certain objectives of the Argentine government, such as the increase in tariffs to incentivize investment in the energy sector, may create inflationary pressures. Inflation in Argentina has contributed to a material increase in our costs of operation, in particular labor costs, and negatively impacted our financial condition.

Inflation rates could escalate in the future, and there is uncertainty regarding the effects that the measures adopted, or that may be adopted in the future, by the Argentine government to control inflation may have. See “—Government intervention may adversely affect the Argentine economy and, as a result, our business and results of operations.” Increased inflation could adversely affect the Argentine economy, which in turn may have an adverse effect on our financial condition and results of operations.

The IAS 29, Financial Reporting in Hyperinflationary Economies , requires that financial statements of any entity whose functional currency is the currency of a hyperinflationary economy, whether based on the historical cost method or on the current cost method, be stated in terms of the measuring unit current at the end of the reporting period. Although the current rate of inflation does not rise to the level required for Argentina to be considered a hyperinflationary economy under IAS 29, if inflation rates continue to escalate in the future, the Argentine peso may qualify as a currency of a hyperinflationary economy according to the guidelines in IAS 29, in which case our financial statements and other financial information may need to be adjusted by applying a general price index and expressed in the measuring unit (the hyperinflationary currency) current at the end of each reporting period. We cannot determine at this time the impact this would have on our financial condition. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting Our Results of Operations—Inflation.”

The credibility of several Argentine economic indices has been called into question, which has led to a lack of confidence in the Argentine economy and could affect your evaluation of this offering and/or the market value of the ADSs

During the administrations of Kirchner and Fernández de Kirchner, the INDEC, the Argentine government’s principal statistical agency, underwent institutional and methodological reforms that gave rise to controversy regarding the reliability of the information that it produced. Reports published by the IMF have stated that their staff uses alternative measures of inflation for macroeconomic surveillance, including data produced by private sources, which have shown inflation rates considerably higher than those published by the INDEC between 2007 and 2015. The IMF also censured Argentina for failing to make sufficient progress, as required under the Articles of Agreement of the IMF, in adopting remedial measures to address the quality of official data, including inflation and GDP data.

40

On January 8, 2016, based on its determination that the INDEC had failed to produce reliable statistical information, particularly with respect to its CPI, GDP, foreign trade and poverty data, the Macri administration declared the national statistical system and the INDEC in a state of administrative emergency through December 31, 2016, which was not renewed. The INDEC suspended publication of certain statistical data until it completed reorganization of its technical and administrative structure to recover its ability to produce sufficient and reliable statistical information. During the first six months of this reorganization period, the INDEC published official CPI figures published by the City of Buenos Aires and the Province of San Luis for reference. On June 29, 2016, the INDEC published a report that included revised GDP data for the years 2004 through 2015. Among other adjustments, in calculating GDP for 2004, the INDEC made changes to the composition of GDP that resulted in a downward adjustment of approximately 12% for that year. In calculating real GDP for subsequent years based on the revised 2004 GDP, the INDEC used deflators that are consistent with its revised methodology to calculate inflation. By understating inflation in the past, the INDEC had overstated growth in real terms. The adjustments made by the INDEC resulted in a determination of real GDP growth for the period 2004-2014 of 44.8%, as opposed to a 63% growth in real terms for the same period resulting from the information used prior to June 29, 2016.

Following the publication of revised data and a new inflation index, on November 9, 2016, the IMF lifted the censorship against Argentina, stating that the country had resumed the publication of data in a manner consistent with its obligations under the Articles of Agreement of the IMF.

The Argentine government’s reforms seek to produce official data that meets international standards. In order to be effective, however, reforms require certain implementation steps and the timely collection of data, the success of which may be outside of the Argentine government’s control. If these reforms cannot be successfully implemented, such failure may adversely affect the Argentine economy, in particular by undermining consumer and investor confidence. The INDEC’s past or future data may be materially revised to reveal a different economic or financial situation in Argentina, which could affect investors’ perception of Argentina, including the market value of the ADSs. In addition, the failure or delays in implementing the expected changes may impair other measures taken by the Central Bank to tackle inflation. This, in turn, could have a negative impact on Argentina’s economy and, as a result, could have an adverse effect on our ability to access international capital markets to finance our operations and growth, adversely affecting our results of operations and financial condition.

Fluctuations in the value of the peso could adversely affect the Argentine economy and, in turn, adversely affect our results of operations

The devaluation of the peso may have a negative impact on the ability of certain Argentine businesses to service their foreign currency-denominated debt, lead to inflation, significantly reduce real wages and jeopardize the stability of businesses, such as ours, whose success depends on domestic market demand and adversely affect the Argentine government’s ability to honor its foreign debt obligations. After several years of moderate variations in the nominal exchange rate, the peso lost more than 30% of its value with respect to the U.S. dollar in each of 2013 and 2014. In 2015, the peso lost approximately 52% of its value with respect to the U.S. dollar, including a 10% devaluation from January 1, 2015 to September 30, 2015 and a 38% devaluation during the last quarter of the year, mainly concentrated after December 16, 2015 once the Macri administration eliminated exchange controls imposed by the prior administration. From January 1, 2016 to December 31, 2016 the peso lost approximately 21.86% of its value with respect to the U.S. dollar. During the first nine months of 2017, the peso lost approximately 8.93% of its value with respect to the U.S. dollar. On January 17, 2018, the exchange rate was Ps.18.85 to US$1.00, as quoted by the Banco de la Nación Argentina for wire transfers ( divisas ).

Persistent high inflation during 2013, 2014, 2015, and 2016, together with formal and de facto exchange controls, resulted in an increasingly overvalued official exchange rate. Compounded by the effects of foreign exchange controls and restrictions on foreign trade, these highly distorted relative prices resulted in the loss of competitiveness of Argentine production, impeded investment and caused economic stagnation. A significant

41

appreciation of the peso against the U.S. dollar also presents risks for the Argentine economy, including the possibility of a reduction in exports (as a consequence of the loss of external competitiveness). Any such appreciation could also have a negative effect on economic growth and employment and reduce tax revenues in real terms.

From time to time, the Central Bank may intervene in the MULC in order to maintain the currency. Additional volatility, appreciation or depreciation of the peso or reduction of the Central Bank’s reserves as a result of currency intervention could adversely affect the Argentine economy, which in turn may have an adverse effect on our financial condition and results of operations.

If the peso devalues further, the negative effects on the Argentine economy could have adverse consequences for our financial condition.

Government intervention may adversely affect the Argentine economy and, as a result, our business and results of operations

The two administrations of President Fernández de Kirchner, who governed from 2007 through December 9, 2015, increased state intervention in the Argentine economy, including through expropriation and nationalization measures, price controls and pervasive exchange controls.

In 2008, the Fernández de Kirchner administration absorbed and replaced the former private pension system for a public “pay as you go” pension system. As a result, all resources administered by the private pension funds, including significant equity interests in a wide range of listed companies, were transferred to a separate fund ( Fondo de Garantía de Sustentabilidad , or the “FGS”) to be administered by the National Social Security Administration ( Administración Nacional de la Seguridad Social , or the “ANSES”). The dissolution of the private pension funds and the transfer of their financial assets to the FGS have had important repercussions on the financing of private sector companies. Debt and equity instruments that previously could be placed with pension fund administrators are now entirely subject to the discretion of the ANSES. Since acquiring equity interests in privately owned companies, through the process of replacing the pension system, the ANSES is entitled to designate representatives of the Argentine government to the boards of directors of those entities. Pursuant to Decree No. 1,278/12, issued by the executive branch on July 25, 2012, the ANSES’s representatives must report directly to the Ministry of Economy and are subject to a mandatory information-sharing regime, under which, among other obligations, the representatives must immediately inform the Ministry of Economy of the agenda for each board of directors’ meeting and provide related documentation.

In April 2012, the Fernández de Kirchner administration decreed the removal of directors and senior officers of YPF, the country’s largest oil and gas company, which was controlled by the Spanish group Repsol, and submitted a bill to the Argentine Congress to expropriate shares held by Repsol representing 51% of the shares of YPF. The Argentine Congress approved the bill in May 2012 through the passage of Law No. 26,741, which declared the production, industrialization, transportation and marketing of hydrocarbons to be activities of public interest and fundamental policies of Argentina and empowered the Argentine government to adopt any measures necessary to achieve self-sufficiency in hydrocarbon supply. In February 2014, the Argentine government and Repsol announced that they had reached an agreement on the terms of the compensation payable to Repsol for the expropriation of the YPF shares. Such compensation totaled US$5 billion payable by delivery of Argentine sovereign bonds with various maturities. The agreement, which was ratified by Law No. 26,932, settled the claim filed by Repsol with the ICSID.

It is widely reported by private sector economists that expropriations, price controls, exchange controls and other direct involvement by the Fernández de Kirchner administration in the economy had an adverse impact on the level of investment in Argentina, the access of Argentine companies to the international capital markets and Argentina’s commercial and diplomatic relations with other countries. Further actions taken by the Argentine government concerning the economy, including decisions with respect to interest rates, taxes, price controls,

42

salary increases, provision of additional employee benefits and foreign exchange controls could continue to have a material adverse effect on Argentina’s economic growth and in turn affect our financial condition and results of operations. Moreover, any additional Argentine government policies established to preempt, or in response to, social unrest could adversely and materially affect the economy, and therefore our business, results of operations and financial condition.

Government measures, as well as pressure from labor unions, could require salary increases or added benefits, all of which could increase companies’ operating costs

In the past, the Argentine government has passed laws and regulations forcing privately owned companies to maintain certain wage levels and provide added benefits for their employees. Additionally, both public and private sector employers have been subject to strong pressure from the workforce and trade unions to grant salary increases and certain benefits. See “—Risks Relating to Our Business—We could be affected by material actions taken by the trade unions.”

Labor relations in Argentina are governed by specific legislation, such as labor Law No. 20,744 and Collective Bargaining Law No. 14,250, which, among other things, dictate how salary and other labor negotiations are to be conducted. Every industrial or commercial activity is regulated by a specific collective bargaining agreement (“CBA”) that groups companies together according to industry sector and trade union. Although the process of negotiation is standardized, each chamber of industrial or commercial activity separately negotiates the increases of salaries and labor benefits with the relevant trade union of such commercial or industrial activity.

Argentine employers, both in the public and private sectors, have experienced significant pressure from their employees and labor organizations to increase wages and to provide additional employee benefits. In August 2012, the Argentine government established a 25% increase in minimum monthly salary to Ps.2,875, effective as of February 2013. The Argentine government increased the minimum salary to Ps.3,300 in August 2013, to Ps.3,600 in January 2014, to Ps.4,400 in September 2014 and to Ps.5,588 in August 2015. It further decreed an increase of the minimum salary applicable to Ps.6,060 in January 2016, to Ps.6,810 in June 2016, to Ps.7,560 in September 2016 and to Ps.8,060 in January 2017. In June 2017, the Ministry of Labor raised the minimum salary to Ps.10,000, effective in three tranches: Ps.8,860 as of July 2017, Ps.9,500 as of January 2018 and Ps.10,000 as of July 2018. Due to high levels of inflation, both public and private sector employers are experiencing significant pressure from unions and their employees to further increase salaries. In 2015, the INDEC published the Coeficiente de Variación Salarial (Salary Variation Index, or the “CVS”), an index that shows the evolution of salaries. The Salaries Index showed an increase of approximately 33.00% in registered private sector salaries in 2016, and 22.46% for the nine-month period ended September 30, 2017.

In the future, the Argentine government could take new measures requiring salary increases or additional benefits for workers, and the labor force and labor unions may apply pressure for such measures. Any such increase in wage or worker benefit could result in added costs and reduced results of operations for Argentine companies, including us. Such added costs could adversely affect our business, financial condition and result of operations.

The implementation of new exchange controls and restrictions on capital inflows and outflows could limit the availability of international credit and could threaten the financial system, adversely affecting the Argentine economy and, as a result, our business

In 2001 and 2002, Argentina imposed exchange controls and transfer restrictions, substantially limiting the ability of companies to retain foreign currency or make payments abroad. After 2002, these restrictions, including those requiring the Central Bank’s prior authorization for the transfer of funds abroad to pay principal and interest on debt obligations, were substantially eased through 2007. In addition to the foreign exchange restrictions applicable to outflows, in June 2005 the Argentine government adopted various rules and regulations that established restrictive controls on capital inflows into Argentina, including a requirement that, for certain

43

funds remitted into Argentina, an amount equal to 30% of the funds must be deposited into an account with a local financial institution as a U.S. dollar deposit for a one-year period without any accrual of interest, benefit or other use as collateral for any transaction.

From 2011 and until President Macri assumed office, the Argentine government increased controls on the sale of foreign currency and the acquisition of foreign assets by local residents, limiting the possibility of transferring funds abroad. Furthermore, under regulations issued since 2012 certain foreign exchange transactions were subject to prior approval by the Federal Administration of Public Income (“AFIP”). Through a combination of foreign exchange and tax regulations, the Fernández de Kirchner administration significantly curtailed access to the MULC by individuals and private-sector entities. In addition, during the last few years under the Fernández de Kirchner administration, the Central Bank exercised a de facto prior approval power for certain foreign exchange transactions otherwise authorized to be carried out under the applicable regulations, such as dividend payments or repayment of principal of intercompany loans as well as the import of goods, by means of regulating the amount of foreign currency available to companies to conduct such transactions. The number of exchange controls introduced in the past and in particular after 2011 during the Fernández de Kirchner administration gave rise to an unofficial U.S. dollar trading market, and the peso/U.S. dollar exchange rate in such market substantially differed from the official peso/U.S. dollar exchange rate. See “Exchange Controls.”

Additionally, the level of international reserves deposited with the Central Bank significantly decreased from US$47.4 billion as of November 1, 2011 to US$25.6 billion as of December 31, 2015, resulting in a reduced capacity of the Argentine government to intervene in the MULC and to provide access to such markets to private sector entities like us. The Macri administration announced a program intended to increase the level of international reserves deposited with the Central Bank through the execution of certain agreements with several Argentine and foreign entities. As a result of the measures taken under such program and due to the issuance by the Argentine government of US$16.5 billion and US$2.75 billion of new debt securities in the international capital markets on April 22, 2016 and July 6, 2016, respectively, the level of international reserves increased to US$38.8 billion as of December 31, 2016. As of November 24, 2017, the level of international reserves of the Central Bank totaled US$55.0 billion, an increase from US$38.8 billion as of December 31, 2016.

Since assuming office, the Macri administration gradually implemented a series of reforms related to the foreign exchange restrictions, including certain currency controls, which had been imposed under the Fernández de Kirchner administration, in order to provide greater flexibility and access to the MULC. On August 8, 2016 the Central Bank issued Communication “A” 6037, which substantially modified the applicable foreign exchange regulations and eliminated the set of restrictions for accessing the MULC. Effective as of July 1, 2017, pursuant to Communication “A” 6244, all regulations that restricted access to the MULC were repealed, leaving in place only the obligation to comply with a reporting regime. Pursuant to Communication “A” 6401, dated December 26, 2017, a new reporting regime was created, pursuant to which the “Survey on the issuance of foreign notes and liabilities by the financial and private non-financial sector,” established by Communication “A” 3602, and the “Survey on direct investments,” established by Communication “A” 4237, were replaced by a unified report on direct investments and debt. Argentine residents must comply with the reporting regime, even when the funds have not been sold in the MULC and/or there is no expectation to access the MULC in the future in relation to the funds that must be reported. For further information, see “Exchange Controls.”

Notwithstanding the measures adopted by the Argentine government, in the future the Argentine government could impose further exchange controls, transfer restrictions or restrictions on the movement of capital and/or take other measures in response to capital flight or a significant depreciation of the peso, which could limit our ability to access the international capital markets and impair our ability to make interest, principal or dividend payments abroad. Such measures could lead to renewed political and social tensions and undermine the Argentine government’s public finances, which could adversely affect Argentina’s economy and prospects for economic growth and, consequently, adversely affect our business and results of operations.

44

A lack of financing for Argentine companies due to the unresolved litigation with holdout bondholders may negatively impact our financial condition or cash flows

In 2005 and 2010, Argentina conducted exchange offers to restructure part of its sovereign debt that had been in default since the end of 2001. As a result of these exchange offers, Argentina restructured over 92% of its eligible defaulted debt.

Commencing in 2002, holdout creditors filed numerous lawsuits against Argentina in several jurisdictions, including the United States, Italy, Germany and Japan. These lawsuits generally assert that Argentina failed to make timely payments of interest and/or principal on their bonds, and seek judgments for the outstanding principal of and/or accrued interest on those bonds. Judgments have been issued in numerous proceedings in the United States and Germany, but to date creditors have not succeeded, with a few minor exceptions, in executing on those judgments.

In 2012, plaintiffs in New York obtained a U.S. district court order enjoining Argentina from making interest payments in full on the bonds issued pursuant to the 2005 and 2010 exchange offers unless Argentina paid the plaintiffs in full, under the theory that the former payments violated the pari passu clause in the 1994 Fiscal Agency Agreement (the “FAA”) governing those non-performing bonds. The Second Circuit Court of Appeals affirmed the so-called pari passu injunctions, and on June 16, 2014 the U.S. Supreme Court denied Argentina’s petition for a writ of certiorari and the pari passu injunctions became effective on June 18 of that year.

In 2014, the Argentine government took a number of steps intended to continue servicing the bonds issued in the 2005 and 2010 exchange offers, which had limited success.

The Argentine government engaged in negotiations with holders of defaulted bonds in December 2015 with a view to bringing closure to fifteen years of litigation. In February 2016, the Argentine government entered into an agreement in principle to settle with certain holders of defaulted debt and put forward a proposal to other holders of defaulted debt, including those with pending claims in U.S. courts, subject to two conditions: (i) obtaining approval by the Argentine Congress and the lifting of the pari passu injunctions. On March 2, 2016, the U.S. district court agreed to vacate the pari passu injunctions, subject to two conditions: first, the repeal of all legislative obstacles to settlement with holders of defaulted debt securities issued under the FAA; and (ii) full payment to holders of pari passu injunctions with whom the Argentine government had entered into an agreement in principle on or before February 29, 2016. The U.S. district court’s order was affirmed by the Second Circuit Court of Appeals on April 13, 2016. On June 30, 2016, the Argentine Congress repealed the legislative obstacles to the settlement and approved the settlement proposal. On April 22, 2016, Argentina issued US$16.5 billion of new debt securities in the international capital markets, and applied US$9.3 billion of these proceeds to satisfy settlement payments on agreements with holders with claims amounting to approximately US$4.2 billion. The District Court ordered the vacatur of all pari passu injunctions upon confirmation of such payments.

As of the date of this prospectus, litigation initiated by bondholders that have not accepted Argentina’s settlement offer continues in several jurisdictions, although the size of the claims involved has decreased significantly.

Although the vacatur of the pari passu injunctions removed a material obstacle to access to capital markets by the Argentine government, future transactions may be affected as litigation with holdout bondholders continues, which in turn could affect the Argentine government’s ability to access international credit markets, thus affecting our ability to finance our growth.

High public expenditures could result in long-lasting adverse consequences for the Argentine economy

In recent years, the Argentine government has substantially increased public expenditures. In 2016, national public sector expenditures increased by 37.0% year over year (measured in nominal Argentine pesos) and the

45

government reported a primary fiscal deficit of 4.6% of GDP, according to the Argentine Ministry of Economy (which is, as of the date of this prospectus, divided into two parts—the Ministry of Treasury and the Ministry of Public Finance). During recent years, the Argentine government has resorted to the Central Bank and to the ANSES to alleviate part of its funding requirements. Moreover, the primary fiscal balance could be negatively affected in the future if public expenditures continue to increase at a rate higher than revenues due to, for example, social security benefits, financial assistance to provinces with financial problems and increased spending on public works and subsidies, including subsidies to the energy and transportation sectors. A further deterioration in fiscal accounts could negatively affect the government’s ability to access the long-term financial markets and could in turn result in more limited access to such markets by Argentine companies. Additionally, a further deterioration in fiscal accounts could affect the Argentine government’s ability to continue subsidies for consumers in the energy sector.

A decline in international prices for Argentina’s main commodity exports could have an adverse effect on Argentina’s economic growth

Argentina’s financial recovery from the 2001-2002 crisis occurred in a context of price increases for Argentina’s commodity exports, such as soy. High commodity prices contributed to the increase in Argentine exports since the third quarter of 2002 and to high government tax on revenues from export withholdings. However, the reliance on the export of certain commodities has caused the Argentine economy to be more vulnerable to fluctuations in their prices.

Commodity prices, including for soy, have declined significantly since peak prices due in part to slower growth in China. A continuing decline in the international prices for Argentina’s main commodity exports could have a negative impact on the levels of government revenues and the government’s ability to service its sovereign debt, and could either generate recessionary or inflationary pressures, depending on the government’s reaction. Either of these results would adversely impact Argentina’s economy and, therefore, our financial condition.

The Argentine economy could be adversely affected by economic developments in other markets and by more general “contagion” effects

Weak, flat or negative economic growth of any of Argentina’s major trading partners, such as Brazil, could adversely affect Argentina’s balance of payments and, consequently, economic growth.

The economy of Brazil, Argentina’s largest export market and the principal source of imports, is currently experiencing heightened negative pressure due to the uncertainties stemming from ongoing political crisis, including the impeachment of Brazil’s president, Ms. Dilma Rousseff. The Brazilian economy contracted by 3.6% during 2016, mainly due to a 4.2% decrease in household consumption and a 10.2% decrease in gross fixed capital formation. A further deterioration of economic conditions in Brazil may reduce demand for Argentine exports and create advantages for Brazilian imports. While the impact of Brazil’s downturn on Argentina cannot be predicted, we cannot exclude the possibility that the Brazilian political and economic crisis could have a further negative impact on the Argentine economy.

The Argentine economy may be affected by “contagion” effects. International investors’ reactions to events occurring in one developing country sometimes appear to follow a “contagion” pattern, in which an entire region or investment class is disfavored by international investors. In the past, the Argentine economy has been adversely affected by such contagion effects on a number of occasions, including the 1994 Mexican financial crisis, the 1997 Asian financial crisis, the 1998 Russian financial crisis, the 1999 devaluation of the Brazilian real, the 2001 collapse of Turkey’s fixed exchange rate regime and the global financial crisis that began in 2008.

The Argentine economy may also be affected by conditions in developed economies, such as the United States, that are significant trading partners of Argentina or have influence over world economic cycles. If

46

interest rates increase significantly in developed economies, including the United States, Argentina and its developing economy trading partners, such as Brazil, could find it more difficult and expensive to borrow capital and refinance existing debt, which could adversely affect economic growth in those countries. Decreased growth on the part of Argentina’s trading partners could have a material adverse effect on the markets for Argentina’s exports and, in turn, adversely affect economic growth. Any of these potential risks to the Argentine economy could have a material adverse effect on our business, financial condition and result of operations.

On June 23, 2016, the United Kingdom voted in favor of exiting the European Union. As of the date of this prospectus, the actions that the United Kingdom will take to effectively exit from the European Union or the length of such process are uncertain. The results of the United Kingdom’s referendum have caused, and are anticipated to continue causing, volatility in the financial markets, which may in turn have a material adverse effect on our business, financial condition and results of operations.

On November 8, 2016, Mr. Donald J. Trump was elected president of the United States. The results of the presidential election have created significant uncertainty about the future relationship between the United States and other countries, including with respect to the trade policies, treaties, government regulations and tariffs that could apply to trade between the United States and other nations. These developments, or the perception that any of them could occur, may have a material adverse effect on global economic conditions and the stability of global financial markets. Any of these factors could depress economic activity and restrict our access to suppliers and have a material adverse effect on our business, financial condition and results of operations.

Risks Relating to the Electric Power Sector in Argentina

The Argentine government has intervened in the electric power sector in the past, and is likely to continue intervening

Historically, the Argentine government has played an active role in the electric power industry through the ownership and management of state-owned companies engaged in the generation, transmission and distribution of electric power. Since 1992 and the privatization of several state-owned companies, the Argentine government has reduced its control over the industry. However, as is the case in most other countries, the Argentine electric power industry remains subject to strict regulation and government intervention. Moreover, to address the Argentine economic crisis of 2001 and 2002, the Argentine government adopted Law No. 25,561 (the “Public Emergency Law”) and other regulations, which made a number of material changes to the regulatory framework applicable to the electric power sector. These changes have had significant adverse effects on electric power generation, distribution and transmission companies and included the freezing of distribution margins, the revocation of adjustment and inflation indexation mechanisms for tariffs, a limitation on the ability of electric power distribution companies to pass on to the consumer increases in costs due to regulatory charges and the introduction of a new price-setting mechanism in the WEM, all of which had a significant impact on electric power generators and caused substantial price differences within the market.

The Fernández de Kirchner administration continued to intervene in the electric power industry by, for example, granting temporary margin increases, proposing a new tariff regime for residents of poverty-stricken areas, increasing remunerations earned by generators for capacity, operation and maintenance services, creating specific charges to raise funds that are transferred to government-managed trust funds that finance investments in generation and distribution infrastructure and mandating investments for the construction of new generation plants and the expansion of existing transmission and distribution networks.

For example, in March 2013, pursuant to Resolution No. 95/13, issued by the former Secretariat of Energy, the Fernández de Kirchner administration suspended the renewal of sales contracts in the term market and execution of new agreements in the WEM, and ordered that any demand not satisfied by Argentine generators must be directly supplied by CAMMESA. As a result, Argentine generators are required to supply capacity and energy to CAMMESA at prices fixed by the former Secretariat of Energy.

47

Since the Macri administration assumed office, the Argentine government has initiated significant reforms to the Argentine electric power industry. On December 16, 2015, the Macri administration declared a state of emergency with respect to the national electric power system that remained in effect until December 31, 2017. The state of emergency allowed the Argentine government to take actions designed to guarantee the supply of electric power in Argentina, such as instructing the Ministry of Energy and Mining to elaborate and implement, with the cooperation of all federal public entities, a coordinated program to guarantee the quality and security of the electric power system and rationalize public entities’ consumption of energy. In addition, the Argentine government and certain provincial governments have approved significant price adjustments and tariff increases applicable to certain generation and distribution companies. Following the tariff increases, preliminary injunctions suspending such increases were requested by customers, politicians and non-governmental organizations that defend customers’ rights, which preliminary injunctions were granted by Argentine courts. Among the different rulings in this respect, two recent rulings issued by the Second Division of the Federal Court of Appeals for the City of La Plata and a federal judge from the San Martín district court led to the suspension of end-users tariff increases of electric power in the Province of Buenos Aires and in the whole territory of Argentina, respectively. Pursuant to these injunctions, (i) the end-user tariff increases granted as of February 1, 2016 were suspended retroactively to that date, (ii) end-user bills sent to customers were not to include the increase and (iii) the amounts already collected from end-users as a consequence of consumption recorded before these rulings had to be reimbursed. However, on September 6, 2016, the Supreme Court denied these injunctions that suspended end-users electric power tariff increases, arguing formal objections and procedural defects and therefore, as of the date of this prospectus, increases of the electric power end-users tariffs are not suspended.

Pursuant to Resolution No. 522/16, the ENRE ordered a public hearing to be held to evaluate the proposals for the full tariff review filed by EDENOR and EDESUR for the period from January 1, 2017 to December 31, 2021. The hearing was held on October 28, 2016. A non-binding public hearing was conducted by the Ministry of Energy and Mining and the ENRE to discuss tariff proposals submitted by distribution companies covering the greater Buenos Aires area (with approximately 15 million inhabitants), including Edenor, for the 2017-2021 period within the framework of the RTI. Following such hearing, on January 31, 2017, the ENRE issued Resolution No. 63/17, pursuant to which such administrative authority approved the tariffs to be applied by EDENOR. In the same sense, Resolution No. 64/17 approved EDESUR’s tariffs.

On February 1, 2017, the ENRE enacted several resolutions, which, among other policy changes, implemented a reduction of electric power tariff subsidies and an increase in electric power tariffs for residential customers. Such increases ranged between 61% and 148%, depending on to the amount of the consumer’s electric power consumption.

Regarding transmission tariffs, seven public hearings were held pursuant to Resolutions Nos. 601/16, 602/16, 603/16, 604/16, 605/16, 606/16 and 607/16 of the ENRE. In such public hearings, the tariff proposals filed by transmission companies Transener S.A., Distrocuyo S.A., Transcomahue S.A., Ente Provincial de Energía de Neuquén, Transba S.A., Transnea S.A., Transnoa S.A. and Transpa S.A. for the period from January 1, 2017 to December 31, 2021 were evaluated. Pursuant to Resolutions Nos. 66/17, 68/17, 69/17, 71/17, 73/17, 75/17, 77/17 and 79/17, the ENRE approved the new applicable tariffs for such companies.

Additionally, in March 2016, the Secretariat of Electric Energy enacted Resolution SEE No. 22/16, through which it adjusted the electric power prices for the sale of energy by generation companies under the Energía Base. See “See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting Our Results of Operations—Our Revenues—The Energía Base.” The Secretariat of Electric Energy cited the fact that WEM prices have been distorted and discourage private sector investment in power generation and that it was necessary to raise tariffs to partially compensate for increasing operation and maintenance costs and to improve the cash flow generation capacity of these companies. On February 1, 2017, the tariff revision process was completed and the new tariff scheme for the following five-year period was enacted.

48

The Argentine government has also established public bidding processes for the development of new generation projects from both thermal and renewable sources. These measures aim not only to satisfy domestic electric power demand, but also to promote investments in the electric power sector and improve the economic situation of the WEM, which, as discussed above, has faced challenges since 2001.

Notwithstanding the recent measures adopted by the Argentine government, we cannot guarantee that the expected changes to the electric power sector will happen as expected, within the anticipated timeframe or at all. It is possible that certain measures may be adopted by the Argentine government that could have a material adverse effect on our business and results of operations, or that the Argentine government may adopt emergency legislation similar to the Public Emergency Law or other similar resolutions in the future that could have a direct impact on the regulatory framework of the electric power industry and indirectly adversely affect the electric power generation industry, and therefore, our business, financial condition and results of operations.

Electricity generators, distributors and transmitters have been materially and adversely affected by emergency measures adopted in response to Argentina’s economic crisis of 2001 and 2002, many of which remain in effect

Since the Argentine economic crisis of 2001 and 2002, Argentina’s electric power sector has been characterized by government regulations and policies that have resulted in significant distortions in the electric power market, particularly with respect to prices, throughout the whole value chain of the sector (generation, transmission and distribution). Historically, Argentine electric power prices were calculated in U.S. dollars and margins were adjusted periodically to reflect variations in relation to costs. In January 2002, the Public Emergency Law authorized the Argentine government to renegotiate its public utility contracts. Under this law, the Argentine government revoked provisions in the public utility contracts related to the adjustment and inflation indexation mechanism. Instead, the tariffs on such contracts were frozen and converted from their original U.S. dollar values to Argentine pesos at a rate of Ps.1.00 per US$1.00. For further information on the changes to the legal framework of the Argentine electric power industry caused by the Public Emergency Law, see “The Argentine Electric Power Sector.”

These measures, coupled with the effect of high inflation and the devaluation of the peso in recent years, led to a significant decline in revenues and a significant increase of costs in real terms, which could no longer be recovered through margin adjustments or market price-setting mechanisms. This situation, in turn, led many public utility companies to suspend payments on their financial debt (which continued to be denominated in U.S. dollars despite the pesification of revenues), effectively preventing these companies from obtaining further financing in the domestic or international credit markets and making additional investments.

After declaring a state of emergency with respect to the national electrical system, the Argentine government increased electric power tariffs in the WEM under the Energía Base. Preliminary injunctions suspending such increases were requested by customers, politicians and non-governmental organizations, and recent rulings suspended the increases in the whole territory of Argentina. On September 6, 2016, the Supreme Court denied these injunctions that suspended end-users electric power tariff increases, and a public hearing to evaluate the proposals for a full tariff review filed by EDENOR and EDESUR was held on October 28, 2016. The tariff increases were approved on January 31, 2017. In addition, the Argentine government issued Resolution SE No. 21/16 calling for a public bid process for the installation of new generation capacity from both thermal and renewable sources, offering generators U.S. dollar-denominated rates linked to generation costs for newly available generation capacity. However, tariffs under the Energía Base remain well below historical levels, although there have been important increases and, they are now denominated in U.S. dollars which mitigates the effect of variations in the foreign exchange rate. These measures, or any future measures, may not be sufficient to address the structural problems created by the economic crisis of 2001 and 2002 and its aftermath, and measures similar to those adopted during the economic crisis may not be enacted in the future.

49

We have, in the recent past, been unable to collect payments, or to collect them in a timely manner, from CAMMESA and other customers in the electric power sector

For the nine-month period ended September 30, 2017 and the year ended December 31, 2016, we derived approximately 78.54% and 74.66%, respectively, of our revenues from our sales to CAMMESA (under the Energía Base, the spot market and remuneration under Resolution No. 724/2008, relating to agreements with CAMMESA to improve existing power generation capacity). In addition, we receive significant cash flows from CAMMESA in connection with the FONINVEMEM and similar programs. Payments to us by CAMMESA, including installments in connection with returns from FONINVEMEM and similar programs, depend upon payments that CAMMESA in turn receives from other WEM agents such as electric power distributors as well as the Argentine government.

In recent years, due to regulatory conditions in Argentina’s electric power sector that affected the profitability and economic viability of power utilities, certain WEM agents defaulted on their payments to CAMMESA, which adversely affected CAMMESA’s ability to meet its payment obligations to electric power generators, including us. In the recent past, when CAMMESA experienced a lack of funds to pay to generators, a significant amount of unpaid balances were converted into LVFVD. See “Business—FONINVEMEM and Similar Programs.” As a consequence of delays in payments that CAMMESA received from other WEM agents in the past, we also saw delays in the payments we received under the Energía Base, receiving payments from CAMMESA within approximately 90 days of month-end, rather than the required 42 days after the date of billing. Such payment delays resulted in higher working capital requirements that we would typically finance with our own financing sources. Since September 2016, CAMMESA has paid without delays, in accordance with the Energía Base. However, CAMMESA may once again be unable to make payments to generators both in respect of energy dispatched and generation capacity availability on a timely basis or in full, which may substantially and adversely affect our financial position and the results of our operations.

Electricity demand may be affected by tariff increases, which could lead generation companies like us to record lower revenues

During the 2001 and 2002 economic crisis, electric power demand in Argentina decreased due to the decline in the overall level of economic activity and the deterioration in the ability of many consumers to pay their electric power bills. In the years following the 2001 and 2002 economic crisis, electric power demand experienced significant growth, increasing at an estimated average of approximately 3.86% per annum from 2002 through 2015 (despite a decline in 2009), due to its reduced cost as a result of certain energy subsidies, freezing of margins and elimination of inflation adjustment provisions in distribution concessions. In March 2016, the Argentine government unified and increased wholesale energy prices for all consumption in Argentina, eliminated certain energy subsidies and implemented an incentive plan (through discounts) for residential customers whose electric power consumption is at least 10.00% lower than their consumption for the same month of the previous year. These measures are currently in an early stage of implementation, and we cannot ascertain as of the date of this prospectus what the effect on our revenues could be. Any significant increase in energy prices to consumers (whether through a tariff increase or through a cut in consumer subsidies) could result in a decline in demand for the energy that we generate. Any material adverse effect on electric power demand, in turn, could lead electric power generation companies, like us, to record lower revenues and results of operations than currently anticipated.

Argentina has certain energy transmission and distribution limitations that adversely affect the capacity of electric power generators to deliver all of the energy they are able to produce, which results in reduced sales

The energy that generators are able to deliver to the transmission system for the further delivery to the distribution system at all times depends on the capacity of the transmission and distribution systems that connects them to it. The transmission and distribution system is currently operating at near full capacity and both transmission and distributors may not be able to guarantee an increased supply of electric power to their

50

customers. In the past years, the increase in demand for electric power resulted in blackouts in Buenos Aires and other cities around Argentina, which results in excess capacity for generators. As a result, the amount of hydroelectric energy and thermal energy generated is larger than what the transmission and distribution systems are capable of transmitting or distributing. Any transmission or distribution limitation for generators could reduce the energy sold, which could adversely affect our financial condition.

Our equipment, facilities and operations are subject to environmental, health and safety regulations

Our generation business is subject to federal and provincial laws, as well as to the supervision of governmental agencies and regulatory authorities in charge of enforcing environmental laws and policies. We operate in compliance with applicable laws and in accordance with directives issued by the relevant authorities and CAMMESA; however, it is possible that we could be subject to controls, which could result in penalties to be imposed on us, such as the termination of the HPDA Concession Agreement. In addition, future environmental regulations could require us to make investments in order to comply with the requirements set by the authorities, instead of making other scheduled investments and, as a result, could have a material adverse effect on our financial condition and our results of operations.

We operate in a heavily regulated sector that imposes significant costs on our business, and we could be subject to fines and liabilities that could have a material adverse effect on our results of operations

We are subject to a wide range of federal, provincial and municipal regulations and supervision, including laws and regulations pertaining to tariffs, labor, social security, public health, consumer protection, the environment and competition. Furthermore, Argentina has 23 provinces and one autonomous city (the City of Buenos Aires), each of which, under the Argentine National Constitution, has power to enact legislation concerning taxes, environmental matters and the use of public space. Within each province, municipal governments can also have powers to regulate such matters. Although the generation of electric power is considered an activity of general interest ( actividad de interés general ) subject to federal legislation, due to the fact that our facilities are located throughout various provinces, we are also subject to provincial and municipal legislation. Future developments in the provinces and municipalities concerning taxes (including sales, security and health and general services taxes), environmental matters, the use of public space or other matters could have a material adverse effect on our business, results of operations and financial condition. Compliance with existing or future legislation and regulations could require us to make material expenditures and divert funds away from planned investments in a manner that could have a material adverse effect on our business, results of operations and financial condition.

In addition, our failure to comply with existing regulations and legislation, or reinterpretations of existing regulations and new legislation or regulations, such as those relating to fuel and other storage facilities, volatile materials, cyber security, emissions or air quality, hazardous and solid waste transportation and disposal and other environmental matters, or changes in the nature of the energy regulatory process may subject us to fines and penalties and have a significant adverse impact on our financial results.

Our power plants are subject to the risk of mechanical or electrical failures and any resulting unavailability may affect our ability to fulfill our contractual and other commitments and thus adversely affect our business and financial performance

Our power generation units are at risk of mechanical or electrical failure and may experience periods of unavailability affecting our ability to generate electric power. For example, certain of our turbogenerators at the Puerto Complex, including generators 5, 6, 7 and 8, began operating in the 1960s and are, therefore, over 50 years old. Because of their age, these generators may face a higher risk of mechanical or electrical failure. Any unplanned unavailability of our generation facilities may adversely affect our financial condition or results of operations.

51

Risks arise for our business from technological change in the energy market

The energy market is subject to far-reaching technological change, both on the generation side and on the demand side. For example, with respect to energy generation, the development of energy storage devices (battery storage in the megawatt range) or facilities for the temporary storage of power through conversion to gas (so-called “power-to-gas-technology”), the increase in energy supply due to new technological applications such as fracking or the digitalization of generation and distribution networks should be mentioned.

New technologies to increase energy efficiency and improve heat insulation, for the direct generation of power at the consumer level, or that improve refeeding (for example, by using power storage for renewable generation) may, on the demand side, lead to structural market changes in favor of energy sources with low or zero carbon dioxide emissions or in favor of decentralized power generation, (for instance, via small-scale power plants within or close to residential areas or industrial facilities.)

If our business is unable to react to changes caused by new technological developments and the associated changes in market structure, our equity, financial or other position, or our results, operation and business, could be materially and adversely affected.

We may face competition

The power generation markets in which we operate are characterized by numerous strong and capable participants, many of which may have extensive and diversified developmental or operating experience (including both domestic and international) and financial resources similar to or significantly greater than ours. See “Business—Competition.” An increase in competition could cause reductions in prices and increase acquisition prices for fuel, raw materials and existing assets and, therefore, adversely affect our results of operations and financial condition.

We compete with other generation companies for the megawatt of capacity that are allocated through public auction processes. On October 7, 2016, the Ministry of Energy finalized the auction process for the installation of new renewable energy units and granted awards in the amount of 1,108.65 MW, including one biomass project, 12 wind energy projects and four solar energy projects. Of these, we were awarded one wind energy project for 99 MW of generating capacity at the price of US$61.50 per MWh. On October 31, 2016, the Ministry of Energy and Mining, pursuant to Resolution No. 252/16, launched Round 1.5 of the RenovAR Program as a continuation of Round 1 and on November 25, 2016, granted awards in the amount of 1281.5 MW, including 10 wind energy projects and 20 solar energy projects. Of these, we were awarded one wind energy project for 48 MW of generating capacity at the price of US$59.38 per MWh. Following Rounds 1 and 1.5 of the RenovAR Program, the Ministry of Energy and Mining pursuant to Resolution No. 275/17, which launched Round 2 of the program on August 17, 2017, granted awards in the amount of 2,043 MW of renewable power capacity. We submitted bids for Round 2 of the RenovAR Program on October 19, 2017 and, on November 29, 2017, we were awarded a wind energy project called, “La Genoveva I,” which will allow us to add an additional capacity of 86.6 MW to our portfolio and to continue to build a presence in the renewable energies sector.

The Secretariat of Electric Energy, pursuant to Resolution SEE No. 287-E/17, called for proposals for supply of electric power to be generated through existing units, the conversion of open combined cycle units into closed combined cycle units or the installation of co-generation units. We submitted bids on August 9, 2017, and, on September 25, 2017, we were awarded the two co-generation projects. Our newly awarded Terminal 6 San Lorenzo and Luján de Cuyo projects have the following two potential sources of income: (i) electric power sales to CAMMESA through PPAs with a 15-year term which are priced in U.S. dollars; and (ii) steam sales pursuant to separate steam supply agreements negotiated with private offtakers, which are expected to be priced in U.S. dollars.

In addition, we have acquired four heavy-duty, highly efficient gas turbines and 130 hectares of land in the north of the Province of Buenos Aires, that could potentially allow us to develop new power capacity that could

52

add 1,255 MW to our total installed capacity through one or more projects working under a simple cycle configuration. For example, we will use a Siemens gas turbine, with a capacity of 286 MW, for the Terminal 6 San Lorenzo co-generation project described above. Our objective is to use the remaining three units and the aforementioned land, in which we have already invested US$134 million, to participate in one or more projects, in future bidding processes called by the Argentine government for new generation capacity. Because of the competition among generation companies in these auction processes, we cannot predict whether we will be awarded the projects and whether we will be able to utilize these assets as intended. In addition, as of the date of this prospectus, we have already paid SEK$381.37 million (which, converted at the exchange rate quoted by the Central Bank as of the date of each payment, equals US$45.46 million) to purchase two additional Siemens gas turbines for our Luján de Cuyo project.

We and our competitors are connected to the same electrical grid that has limited capacity for transportation, which, under certain circumstances, may reach its capacity limits. Therefore, new generators may connect, or existing generators may increase, their outputs and dispatch more electric power to the same grid that would prevent us from delivering our energy to our customers. In addition, the Argentine government (or any other entity on its behalf) might not make the necessary investments to increase the system’s capacity, which, in case there is an increase of energy output, would allow us and existing and new generators to efficiently dispatch our energy to the grid and to our customers. As a result, an increase in competition could affect our ability to deliver our product to our customers, which would adversely affect our business, results of operations and financial condition.

Our business is subject to risks arising from natural disasters, catastrophic accidents and terrorist attacks

Our generation facilities, or the third-party fuel transportation or electric power transmission infrastructure that we rely on, may be damaged by flooding, fires, earthquakes and other catastrophic disasters arising from natural or accidental or intentional human causes. We could experience severe business disruptions, significant decreases in revenues based on lower demand arising from catastrophic events, or significant additional costs to us not otherwise covered by business interruption insurance clauses. There may be an important time lag between a major accident, catastrophic event or terrorist attack and our definitive recovery from our insurance policies, which typically carry non-recoverable deductible amounts, and in any event are subject to caps per event. In addition, any of these events could cause adverse effects on the energy demand of some of our customers and of consumers generally in the affected market. Some of these considerations, could have a material adverse effect on our business, financial condition and our result of operations.

We may be subject to expropriation or similar risks

All or substantially all of our assets are located in Argentina. We are engaged in the business of power generation and, as such, our business or our assets may be considered by the government to be a public service or essential for the provision of a public service. Therefore, our business is subject to political uncertainties, including expropriation or nationalization of our business or assets, loss of concessions, renegotiation or annulment of existing contracts, and other similar risks. For example, the HPDA Concession Agreement pursuant to which we are permitted to operate our Piedra del Águila plant expires on December 29, 2023.

In such an event, we may be entitled to receive compensation for the transfer of our assets. However, the price received may not be sufficient, and we may need to take legal actions to claim appropriate compensation. Our business, financial condition and results of our operations could be adversely affected by the occurrence of any these events.

Changes in regulatory frameworks under which we sell our electricity may affect our financial condition and results of operations

We currently sell our capacity availability and electricity under various regulatory frameworks, including the Energía Base and Energía Plus. See “Business—Our Customers” and “The Argentine Electric Power Sector.”

53

On December 16, 2016, the Argentine government declared a state of emergency with respect to the national electrical system until December 31, 2017. We cannot assure you what further changes the Argentine government may make to the Energía Base or the other regulatory frameworks under which we sell power availability or electricity, including whether these changes future changes will not negatively impact our results of operations. Moreover, we cannot assure you under what regulatory framework we will be able to sell our generation capacity and electricity in the future.

We cannot assure you that changes in the current applicable laws and regulations, or adverse judicial or administrative interpretations of such laws and regulations, will not adversely affect our results of operations. In addition, some of the measures proposed by the new government may also generate political and social opposition, which may in turn prevent the new government from adopting such measures as proposed.

Risks Relating to Our Business

Our results depend largely on the compensation established by the Secretariat of Electric Energy and received from CAMMESA

Since the enactment of Resolution SE No. 95/13, issued by the former Secretariat of Electric Energy, as amended, our compensation has depended largely on the variable compensation determined by energy output and availability. This resolution was replaced in February 2017 by Resolution SEE No. 19/17, issued by Secretariat of Electric Energy. Except for sales under contracts, revenues from energy production are paid by CAMMESA under the Energía Base based on a fixed and variable costs system which was determined by the Secretariat of Electric Energy pursuant to the new Resolution SEE No. 19/17. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting Our Results of Operations—Our Revenues—The Energía Base” and “Risk Factors—Risks Relating to the Electric Power Sector in Argentina—We have, in the recent past, been unable to collect payments, or to collect them in a timely manner, from CAMMESA and other customers in the electric power sector.” These tariffs under the Energía Base, which were increased in February, May and November 2017, are denominated in U.S. dollars. The resulting sales are converted into Argentine pesos at the exchange rate as of the last day of the month of the transaction and are paid 42 days later.

As a result of this system, our revenues are highly dependent on actions taken by regulatory authorities. Any change in the current system could have a material adverse effect on our revenues and, as a result, our results of operations.

Factors beyond our control may affect our ability to win public bids for new generation capacity, or affect or delay the completion of new power plants once we have been awarded projects

Our business plan contemplates an investment in new energy generation projects in order to expand our generating capacity by more than 2,020.27 MW. This includes more than 628.27 MW from renewable sources, including wind energy projects, as well as the installation of new thermal generation units with an installed generating capacity of 1,392 MW.

On October 7, 2016, the Ministry of Energy finalized the auction process for the installation of new renewable energy units and granted awards in the amount of 1,108.65 MW. Of these, we were awarded one wind energy project for 99 MW of generating capacity at the price of US$61.50 per MWh. On October 31, 2016, the Ministry of Energy and Mining, pursuant to Resolution No. 252/16, launched Round 1.5 of the RenovAR Program as a continuation of Round 1 and on November 25, 2016, granted awards in the amount of 1281.5 MW. Of these, we were awarded one wind energy project for 48 MW of generating capacity at the price of US$59.38 per MWh. Following Rounds 1 and 1.5 of the RenovAR Program, the Ministry of Energy and Mining pursuant to Resolution No. 275/17, which launched Round 2 of the program on August 17, 2017 and granted awards in the amount of 2,043 MW of renewable power capacity. We submitted bids for Round 2 of the RenovAR Program on October 19, 2017 and, on November 29, 2017, we were awarded a wind energy project called, “La Genoveva I,” which will allow us to add an additional capacity of 86.6 MW to our portfolio and to continue to build a presence in the renewable energies sector.

The Secretariat of Electric Energy, pursuant to Resolution SEE No. 287-E/17, called for proposals for supply of electric power to be generated through existing units, the conversion of open combined cycle units into closed combined cycle units or the installation of co-generation units. We submitted bids on August 9, 2017, and, on September 25, 2017, we were awarded the two co-generation projects with the characteristics set forth in the table below. Our newly awarded Terminal 6 San Lorenzo and Luján de Cuyo projects have the following two potential sources of income: (i) electric power sales to CAMMESA through PPAs with a 15-year term which are priced in U.S. dollars; and (ii) steam sales pursuant to separate steam supply agreements negotiated with private offtakers, which are expected to be priced in U.S. dollars.

In addition, we have acquired four heavy-duty, highly efficient gas turbines and 130 hectares of land in the north of the Province of Buenos Aires, that could potentially allow us to develop new power capacity that could add 1,255 MW to our total installed capacity through one or more projects working under a simple cycle configuration. For example, we will use a Siemens gas turbine, with a capacity of 286 MW, for the Terminal 6 San Lorenzo co-generation project described above. Our objective is to use the remaining three units and the aforementioned land, in which we have already invested US$134 million, to participate, through one or more projects, in future bidding processes called by the Argentine government for new generation capacity. Because of the competition among generation companies in these auction processes, we cannot predict whether we will be awarded the projects and whether we will be able to utilize these assets as intended. In addition, as of the date of this prospectus, we have already paid SEK$381.37 million (which, converted at the exchange rate quoted by the Central Bank as of the date of each payment, equals US$45.46 million) to purchase two additional Siemens gas turbines for our Luján de Cuyo project.

Delays in construction or commencement of operations of expanded capacity in our existing power plants or our new power plants could lead to an increase in our financial needs and also cause our financial returns on new investments to be lower than expected, which could materially adversely affect our financial condition and results of operations.

Factors that may impact our ability to commence operations at our existing power plants or build new power plants include: (i) the failure of contractors to complete or commission the facilities or auxiliary facilities by the agreed-upon date or within budget; (ii) the unexpected delays of third parties such as gas or electric power distributors in providing or agreeing to project milestones in the construction or development of necessary infrastructure linked to our generation business; (iii) the delays or failure by our turbine suppliers in providing fully operational turbines in a timely manner; (iv) difficulty or delays in obtaining the necessary financing in terms satisfactory to us or at all; (v) delays in obtaining regulatory approvals, including environmental permits; (vi) court rulings against governmental approvals already granted, such as environmental permits; (vii) shortages or increases in the price of equipment reflected through change orders, materials or labor; (viii) opposition by local and/or international political, environmental and ethnic groups; (ix) strikes; (x) adverse changes in the political and regulatory environment in Argentina; (xi) unforeseen engineering, environmental and geological problems; and (xii) adverse weather conditions, natural disasters, accidents or other unforeseen events. Any cost overruns could be material. In addition, any of these other factors may cause delays in the completion of expanded capacity at our existing power plants or the construction of our new power plant, which could have a material adverse effect on our business, financial condition and results of operations. These delays may also result in short-term sanctions by CAMMESA and, in extreme cases, sanctions for the duration of the contract.

Factors beyond our control may delay the completion of CVOSA’s combined cycle plant

We expect to receive cash flows from CVOSA’s combined cycle plant, which is expected to have 816 MW of installed generating capacity and to be operational during the first quarter of 2018.

Delays in the construction of CVOSA’s combined cycle plant or a delay in the commencement of its operations could delay the start of payments by CAMMESA of the monthly installments for our energy sales from 2008 to 2011. As of September 30, 2017, the receivables for sale of energy for the period of 2008 to 2011

55

totaled Ps.1.29 billion. After the combined cycle plant becomes operational, the amount due will be converted into U.S. dollars at the exchange rate effective at the date of the agreement, which was Ps.3.97 per U.S. dollar. The U.S. denominated monthly payments under the CVO agreement are payable in pesos, converted at the applicable exchange rate in place at the time of each monthly payment. A delay in such payments could have a material adverse effect on our business, financial condition and results of operations. See “Business—FONINVEMEM and Similar Programs.”

Our business may require substantial capital expenditures for ongoing maintenance requirements and the expansion of our installed generation capacity

Incremental capital expenditures may be required to fund ongoing maintenance necessary to maintain our power generation and operating performance and improve the capabilities of our electric power generation facilities. Furthermore, capital expenditures will be required to finance the cost of our current and future expansion of our generation capacity. If we are unable to finance any such capital expenditures in terms satisfactory to us or at all, our business and the results of our operations and financial condition could be adversely affected. Our financing ability may be limited by market restrictions on financing availability for Argentine companies. See “—Risk Relating to Argentina— A lack of financing for Argentine companies due to the unresolved litigation with holdout bondholders, may negatively impact our financial condition or cash flows” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

If the conditions for the La Plata Plant Sale are not met, our results of operations could be adversely affected

On December 20, 2017, YPF EE accepted our offer to sell the La Plata plant, subject to certain conditions. The effective transfer of the La Plata plant is subject to the following conditions: (i) the termination of a due diligence process during which YPF can, at its own discretion, terminate the La Plata Plant Sale; (ii) the payment by YPF EE of the purchase price for the La Plata Plant; (iii) the extension of our steam supply agreement with YPF at our Luján de Cuyo plant for a period of up to 24 months from January 1, 2019 under the same terms as our existing steam supply agreement, which we expect to sign in January 2018; (iv) we and YPF EE shall have complied with the regulation in force in connection with the resale of the aggregate transportation capacity under a FTC contract to YPF EE, and MEGSA ( Mercado Eléctrico de Gas ) shall have awarded such aggregate transportation capacity under the FTC contract to YPF EE; (v) the renewal of two contracts between us and certain third parties and the acceptance by such third parties of the assignment of such contracts to YPF EE; and (vi) other formal conditions. We will effectively transfer the La Plata plant to YPF EE on the La Plata Plant Sale Effective Date.

If the La Plata Plant Sale does not occur, we will continue to be subject to certain obligations upon the termination of our agreement with YPF for energy and steam sales relating to the La Plata plant, which, with respect to the supply of steam to YPF, has been extended for a period of five months from October 31, 2017. Upon termination, unless the agreement is extended, we must dismantle all facilities, equipment, tools and any other assets making up the co-generation plant, including the civil works, within 180 days of the end of the agreement and without any notice requirements. We are solely responsible for the expenses arising from dismantling such goods and facilities, and we have made a provision at September 30, 2017 for such expenses in the amount of Ps.131 million. For more information, see “Unaudited Pro Forma Consolidated Financial Information.”

The non-renewal or early termination of the HPDA Concession Agreement would adversely affect our results of operations

The HPDA Concession Agreement executed between us and the Argentine government, pursuant to which we are permitted to operate our Piedra del Águila plant, expires on December 29, 2023. This plant has a total installed capacity of 1,440 MW, and it represented approximately 15.12% of our total generation and 12.46% of our revenues in 2016, and approximately 17.46% of our total generation and 13.90% of our revenues in the nine-month period

56

ended September 30, 2017. We currently intend to renew the HPDA Concession Agreement prior to its expiration. If the HPDA Concession Agreement expires without renewal, we will be required to revert the assets to the Argentine government. The HPDA Concession Agreement also contains various requirements related to the operation of the hydroelectric plant and compliance with laws and regulations. The non-performance of the HPDA Concession Agreement could give rise to certain penalties and even the termination of the concession. If the concession were terminated, it would be granted to a new company organized by the Argentine government and a tender offer would be carried out for selling the new company’s shares of stock. The proceeds to be received by us in such tender offer would be calculated based on a formula in which the proceeds of the tender decrease as the expiration of the concession term comes closer. Any non-renewal or early termination of the HPDA Concession Agreement would materially and adversely affect our financial condition and results of operation.

Our interests in TJSM, TMB and CVOSA may be significantly diluted

As of the date of this prospectus, we have a 30.8752% interest in TJSM and a 30.9464% interest in TMB, both companies that are engaged in managing the purchase of equipment, building, operating and maintaining power plants constructed under the FONINVEMEM program. We have the right to name two out of nine directors on the board of directors of each company. As of the date of this prospectus, we also own 56.19% of CVOSA, the company that operates the thermal power plant in Timbues. After ten years of operations of each company (which will occur on February 2, 2020 for TJSM, January 7, 2020 for TMB and 10 years after the date on which CVOSA begins to operate in the future), each company is entitled to receive property rights to such power plants from the respective trusts currently holding such power plants. At such time, since the Argentine government financed part of the construction, it will be incorporated as a shareholder of TJSM, TMB and CVOSA, and our interests in TJSM, TMB and CVOSA may be diluted. In the case of TJSM and TMB, we cannot estimate the exact effects of such potential dilution due to the fact that the Argentine government’s stake in these companies depends on the funds provided by the Argentine government for the construction of each plant, which has not yet been defined. In the case of CVOSA, although the effect of the potential dilution has also not yet been defined for the same reasons, the Argentine government’s stake in CVOSA will be at least 70% pursuant to FONINVEMEM arrangements for CVOSA. Any dilution of our interest in TJSM, TMB or CVOSA could reduce our income, which could adversely affect our results of operations. See “Business—FONINVEMEM and Similar Programs.”

Future changes in the rainfall amounts in the Limay River basin could adversely affect the revenues from the Piedra del Águila concession and, therefore, our financial results

As a hydroelectric facility, Piedra del Águila depends on the availability of water resources in the Limay River basin for electric power generating purposes, which in turn depends on the rainfall amounts in the area. In 1996, 2007 and 2012, and in particular in 1998, 1999 and 2016, the area experienced record-low rainfall levels. Lack of water resulted in lower electric power generation and, therefore, lower revenue. However, rainfall levels, and therefore electric generation, were significantly higher than average during 1995, 2001, 2002, 2005 and 2006. For more information about Piedra del Águila’s seasonality, see “Business—Seasonality.”

In the event of critically low water levels, the Intergovernmental Basin Authority, which is in charge of managing the basin of the Limay, Neuquén and Negro rivers, is entitled to manage the water flows according to its flow control standards, which could result in lower water resources for us, which in turn, would result in decreased generation activities. Further, under the HPDA Concession Agreement, we are not entitled to receive any compensation for revenue losses as a result of such actions.

The Limay River basin’s flow may not be sufficient to maintain a regular generation level at Piedra del Águila and the enforcement authority may implement unfavorable measures for Piedra del Águila, and therefore, for us, which could adversely affect our financial condition and our results of operations.

Our ability to operate wind farms profitably is highly dependent on suitable wind and associated weather conditions

The amount of energy generated by, and the profitability of, wind farms are highly dependent on climate conditions, particularly wind conditions, which can vary materially across locations, seasons and years. Variations in wind conditions at wind farm sites occur as a result of daily, monthly and seasonal fluctuations in wind currents and, over the longer term, as a result of more general climate changes and shifts. Because turbines will only operate when wind speeds fall within certain specific ranges that vary by turbine type and manufacturer, if wind speeds fall outside or towards the lower end of these ranges, energy output at our wind farms would decline.

If in the future the wind resource in the areas where our wind farms are located is lower than expected, electricity production at such wind farms would be lower than expected and consequently could materially adversely affect our results of operations.

Our insurance policies may not fully cover damage, and we may not be able to obtain insurance against certain risks

We maintain insurance policies intended to mitigate our losses due to customary risks. These policies cover our assets against loss for physical damage, loss of revenue and also third-party liability. However, we may not have sufficient insurance to cover any particular risk or loss. If an accident or other event occurs that is not covered by our current insurance policies, we may experience material losses or have to disburse significant amounts from our own funds, all of which could have a material adverse effect on our operations and financial position. In addition, an insufficiency in our insurance policies could have an adverse effect on us. In such case, our financial condition and our results of operations could be adversely affected. See “Business—Insurance.”

Our generation operations require us to handle hazardous elements such as fuels, which could potentially result in damage to our facilities or injuries to our personnel

Although we comply with all applicable environmental safety laws and best practices, any accident involving the fuels with which we operate could have adverse environmental consequences and could damage our industrial facilities or our personnel.

Any structural damage to the dam or any other structure located in any of our hydroelectric plants could compromise its electric power generating capacity. Any generation constraints resulting from structural damage could have a material adverse effect on our financial condition and results of operations.

We may be exposed to lawsuits and or administrative proceedings that could adversely affect our financial condition and results of operations

In the ordinary course of our business we enter into agreements with CAMMESA and other parties. Even though we do not currently have any material litigation or administrative proceeding, litigation and/or regulatory proceedings are inherently unpredictable, and excessive verdicts do occur. Adverse outcomes in lawsuits and investigations could result in significant monetary damages, including indemnification payments, or injunctive relief that could adversely affect our ability to conduct our business and may have a material adverse effect on our financial condition and results of operations.

Energy demand is seasonal, largely due to climate conditions

Energy demand fluctuates according to the season and climate conditions may materially and adversely impact energy demand. During the summer (December through March), energy demand may increase significantly due to the need for air conditioning and, during winter (June through August), energy demand may

58

fluctuate according to the needs for lighting and heating. As a result, seasonal changes could materially and adversely affect the demand for energy and, consequently, affect our results of operations and financial condition (in particular sales derived from the Energía Plus regulatory framework, which is dependent on demand rather than on capacity committed under contract).

We may undertake acquisitions and investments to expand or complement our operations that could result in operating difficulties or otherwise adversely affect our financial conditions and results of operations

In order to expand our business, from time to time, we may carry out acquisitions and investments which offer added value and are consistent with or complementary to our business strategy.

For example, in 2015, we acquired: (i) a direct and indirect interest of 24.99% in DGCU’s stock capital; and (ii) a direct and indirect interest of 44.10% of DGCE’s stock capital, both of which operate in a highly regulated industry. The results of these companies’ operations are influenced by the applicable regulatory framework and the interpretation and enforcement of such regulatory framework by ENARGAS, the governmental authority created to regulate privatized natural gas transmission and distribution companies. Their licenses are subject to revocation under certain circumstances. If any of these events were to occur, it could have a material adverse effect on them and, as a result, on us.

In connection with potential acquisition and investment transactions, we may be exposed to various risks, including those arising from: (i) not having accurately assessed the value, future growth potential, strengths, weaknesses and potential profitability of potential acquisition targets; (ii) difficulties in successfully integrating, operating, maintaining or managing newly-acquired operations, including personnel; (iii) unexpected costs of such transactions; or (iv) unexpected contingent or other liabilities or claims that may arise from such transactions. If any of these risks were to materialize, it could adversely affect our financial condition and results of operations.

If we were to acquire another energy company in the future, such acquisition could be subject to the Argentine Antitrust Authority’s approval

The Antitrust Law provides that any transactions involving the acquisition, transfer or control of another company’s assets will be subject to the Comisión Nacional de Defensa de la Competencia (CNDC) (“Argentine Antitrust Authority”) prior consent and approval in the event that (i) the total revenues of the companies involved for the last fiscal year exceeds the sum of Ps.200 million in Argentina; and (ii) the transaction amount or the value of the transferred assets located in Argentina exceeds Ps.20 million.

The Argentine Antitrust Authority will determine whether any acquisition subject to its prior approval negatively impacts competitive conditions in the markets in which we compete or adversely affects consumers in these markets. Although we are not contemplating any business combination as of the date of this prospectus, if the Argentine Antitrust Authority were to reject any business combination or if such authority were to take any action to impose conditions or performance commitments on us as part of the approval process for any business combination, it could adversely affect our financial condition and results of operations and prevent us from achieving the anticipated benefits of such acquisition.

We depend on senior management and other key personnel for our current and future performance

Our current and future performance depends to a significant degree on our qualified senior management team, and on our ability to attract and retain qualified management. Our future operations could be harmed if any of our senior executives or other key personnel ceased working for us. Competition for senior management personnel is intense, and we may not be able to retain our personnel or attract additional qualified personnel. The loss of a member of senior management may require the remaining executive officers to divert immediate and substantial attention to fulfilling his or her duties and of seeking a replacement. Any inability to fill vacancies in our senior executive positions on a timely basis could harm our ability to implement our business strategy, which would harm our business and results of operations.

59

We could be affected by material actions taken by the trade unions

Although we have stable relationships with our work force, in the past we experienced organized work stoppages and strikes, and we may face such work stoppages or strikes in the future. Labor claims are common in the Argentina energy sector, and in the past, unionized employees have blocked access and caused damages to the facilities of various companies in the industry. Moreover, we have no insurance coverage for business interruptions caused by workers’ actions, which could have an adverse effect on our results of operations.

We are subject to anticorruption, anti-bribery, anti-money laundering and other laws and regulations

We are subject to anti-corruption, anti-bribery, anti-money laundering and other laws and regulations. We may be subject to investigations and proceedings by authorities for alleged infringements of these laws. Although we perform compliance processes and maintain internal control systems, these proceedings may result in fines or other liabilities and could have a material adverse effect on our reputation, business, financial conditions and result of operations. If any such subsidiaries, employees or other persons engage in fraudulent, corrupt or other unfair business practices or otherwise violate applicable laws, regulations or internal controls, we could become subject to one or more enforcement actions or otherwise be found to be in violation of such laws, which may result in penalties, fines and sanctions and in turn adversely affect our reputation, business, financial condition and result of operations.

Our ability to generate electricity at our thermal generation plants partially depends on the availability of natural gas and, to a lesser extent, liquid fuel.

The supply and price of natural gas and liquid fuel used in our thermal generation plants has been in the past, and may in the future be, affected by, among other things, the availability of natural gas and liquid fuel in Argentina, given the current shortage of natural gas supply and declining reserves in Argentina. In particular, many oil and gas fields in Argentina are mature and in recent years have not been subject to significant investment into development and exploration activities and, therefore, reserves are likely to be depleted.

Pursuant to Resolution No. 95/2013, as amended, CAMMESA is in charge of managing and supplying all fuels required to run our thermal plants. If in the future we were to become required to purchase our own natural gas or liquid fuel from third parties, we cannot assure you that we will be able to purchase natural gas or liquid fuel at prices that are fully reimbursable by CAMMESA and, even if CAMMESA accepted to reimburse us for such amounts, it may be uncertain when such reimbursements would occur. In addition, natural gas delivery depends on the infrastructure (including barge facilities, roadways and natural gas pipelines) available to serve each generation facility. As a result, our thermal plants are subject to the risks of disruptions or curtailments in the fuel delivery chain and infrastructure. Any such disruption or curtailment may result in the unavailability, or higher prices, of natural gas or liquid fuel. Moreover, if in the future we are required to purchase our own natural gas or liquid fuel from third parties at prices that are not fully reimbursable by CAMMESA, such situation may have a material adverse effect on our financial condition and results of operations.

Risks Relating to our Shares and ADSs

It may be difficult for you to obtain or enforce judgments against us

We are incorporated in Argentina. All of our directors and executive officers reside outside the United States, and substantially all of our and their assets are located outside the United States. As a result, it may not be possible for you to effect service of process within the United States upon these persons or to enforce judgments against them or us in U.S. courts. We have been advised by our special Argentine counsel, Bruchou, Fernández Madero & Lombardi, that there is doubt as to the enforceability in original actions in Argentine courts of liabilities predicated solely on U.S. federal securities laws and as to the enforceability in Argentine courts of judgments of U.S. courts obtained in actions predicated upon the civil liability provisions of U.S. federal securities laws. The enforcement of such judgments will be subject to compliance with certain requirements

60

under Argentine law, such as Articles 517 through 519 of the Argentine Code of Civil and Commercial Procedure, including the condition that such judgments do not violate the principles of public policy of Argentine Law, as determined by an Argentine court. In addition, an Argentine court will not order an attachment on property located in Argentina and determined by such court to be essential for the provision of a public service.

Future exchange controls and restrictions on the repatriation of capital from Argentina may impair the ability of holders of ADSs to receive dividends and distributions on, and the proceeds of any sale of, the shares underlying the ADSs, which could affect the market value of the ADSs

In 2001 and 2002 Argentina imposed exchange controls and transfer restrictions, substantially limiting the ability of companies to retain foreign currency or make payments abroad, including payments of dividends. In addition, new regulations were issued in the last quarter of 2011, which significantly curtailed access to the MULC by individuals and private sector entities. More recently, since December 2015 the new Argentine administration has lifted many of the foreign exchange restrictions imposed in 2011, including the lifting of certain restrictions for the repatriation of portfolio investment by non-resident investors. As a consequence, with respect to the proceeds of any sale of common shares underlying the ADSs, as of the date of this prospectus, the conversion from pesos into U.S. dollars and the remittance of such U.S. dollars abroad is not subject to prior approval of the Argentine Central Bank, provided that the foreign beneficiary is either a natural or legal person residing in or incorporated and established in jurisdictions, territories or associated states that are considered “cooperators for the purposes of fiscal transparency.”

Argentina may impose new stricter exchange controls and transfer restrictions in the future, among other things, in response to capital flight or a significant depreciation of the peso. In such a case, the ADS Depositary may be prevented from converting pesos it receives in Argentina for the account of the ADS holders. If this conversion is not possible, the deposit agreement allows the ADS Depositary to distribute the foreign currency only to those ADS holders to whom it is possible to do so. If the exchange rate fluctuates significantly during a time when the ADS Depositary cannot convert the foreign currency, holders of our ADSs may lose some or all of the value of the dividend distribution. Also, if payments cannot be made in U.S. dollars abroad, the repatriation of any funds collected by foreign investors in pesos in Argentina may be subject to restriction. In such event, the ability of our foreign shareholders and holders of ADSs to obtain the full value of their shares and ADSs and the market value of our shares and ADSs may be adversely affected.

We will be traded on more than one market and this may result in price variations; in addition, investors may not be able to easily move shares for trading between such markets

Prior to the date of this prospectus, our common shares were listed on the BYMA. We have applied to list the ADSs on the NYSE. Any markets that may develop for our common shares or for the ADSs may not have liquidity and the price at which the common shares or the ADSs may be sold is uncertain.

Trading in the ADSs or our common shares on these markets will take place in different currencies (U.S. dollars on the NYSE and pesos on the BYMA), and at different times (resulting from different time zones, different trading days and different public holidays in the United States and Argentina). The trading prices of the securities on these two markets may differ due to these and other factors. Any decrease in the price of our common shares on the BYMA could cause a decrease in the trading price of the ADSs on the NYSE. Investors could seek to sell or buy our shares to take advantage of any price differences between the markets through a practice referred to as arbitrage. Any arbitrage activity could create unexpected volatility in both our share prices on one exchange, and the ADSs available for trading on the other exchange. In addition, holders of ADSs will not be immediately able to surrender their ADSs and withdraw the underlying common shares for trading on the other market without effecting necessary procedures with the ADS Depositary. This could result in time delays and additional cost for holders of ADSs.

61

Under Argentine Corporate Law, shareholder rights may be fewer or less well defined than in other jurisdictions

Our corporate affairs are governed by our bylaws and by Argentine Law No. 19,550, as amended (the “Argentine Corporate Law”), which differ from the legal principles that would apply if we were incorporated in a jurisdiction in the United States (such as Delaware or New York), or in other jurisdictions outside Argentina. Thus, the rights of holders of our ADSs or holders of our common shares under the Argentine Corporate Law to protect their interests relative to actions by our 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 illegal under Argentine law, the Argentine securities markets may not be as highly regulated or supervised as the U.S. securities markets or markets in some of the other jurisdictions. In addition, rules and policies against self-dealing and regarding the preservation of shareholder interests may be less well defined and enforced in Argentina than in the United States, or other jurisdictions outside Argentina, putting holders of our common shares and the ADSs at a potential disadvantage.

Holders of our common shares and the ADSs located in the United States may not be able to exercise preemptive or accretion rights

Under the Argentine Corporate Law, if we issue new shares as part of a capital increase, our shareholders may have the right to subscribe to a proportional number of shares to maintain their existing ownership percentage. Rights to subscribe for shares in these circumstances are known as preemptive rights. In addition, shareholders are entitled to the right to subscribe for the unsubscribed shares remaining at the end of a preemptive rights offering on a pro rata basis, known as accretion rights. Upon the occurrence of any future increase in our capital stock, United States holders of common shares or ADSs will not be able to exercise the preemptive and related accretion rights for such common shares or ADSs unless a registration statement under the Securities Act is effective with respect to such common shares or ADSs or an exemption from the registration requirements of the Securities Act is available. We are not obligated to file a registration statement with respect to those common shares or ADSs. We may not file such a registration statement, or an exemption from registration may not be available. Unless those common shares or ADSs are registered or an exemption from registration applies, a U.S. holder of our common shares or ADSs may receive only the net proceeds from those preemptive rights and accretion rights if those rights can be sold by the ADS Depositary; if they cannot be sold, they will be allowed to lapse. Furthermore, the equity interest of holders of common shares or ADSs located in the United States may be diluted proportionately upon future capital increases.

Non-Argentine companies that own our common shares directly and not as ADSs may not be able to exercise their rights as shareholders unless they are registered in Argentina

Under Argentine law, foreign companies that own shares in an Argentine corporation are required to register with the Inspección General de Justicia (Superintendency of Legal Entities, or the “IGJ”), in order to exercise certain shareholder rights, including voting rights. Holders owning common shares directly (rather than ADSs) that are non-Argentine companies and are not registered with the IGJ may be limited in their ability to exercise their rights as holders of our common shares.

Voting rights, and other rights, with respect to the ADSs are limited by the terms of the deposit agreement

Holders may exercise voting rights with respect to the common shares underlying ADSs only in accordance with the provisions of the deposit agreement. There are no provisions under Argentine law or under our bylaws that limit ADS holders’ ability to exercise their voting rights through the ADS Depositary with respect to the underlying common shares, except if the ADS Depositary is a foreign entity and it is not registered with the IGJ. The ADS Depositary is registered with the IGJ. However, there are practical limitations upon the ability of ADS holders to exercise their voting rights due to the additional procedural steps involved in communicating with such holders. For example, Law No. 26,831 requires us to notify our shareholders by publications in certain official

62

and private newspapers of at least 20 and no more than 45 days in advance of any shareholders’ meeting. ADS holders will not receive any notice of a shareholders’ meeting directly from us. In accordance with the deposit agreement, we will provide the notice to the ADS Depositary, which will in turn, if we so request, as soon as practicable thereafter provide to each ADS holder:

To exercise their voting rights, ADS holders must then provide instructions to the ADS Depositary how to vote the shares underlying ADSs. Because of the additional procedural step involving the ADS Depositary, the process for exercising voting rights will take longer for ADS holders than for holders of our common shares. Except as described in this prospectus, holders of the ADS will not be able to exercise voting rights attaching to the ADSs.

Also, section 7.6 of the deposit agreement provides that each of the parties to the deposit agreement (including, without limitation, each holder and beneficial owner) waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding against us and/ or the ADS Depositary. This provision may have the effect of limiting and discouraging lawsuits against us and/ or the ADS Depositary. Moreover, you may not be able to exercise your right to vote and you may have no legal remedy if the shares underlying your ADSs are not voted as you requested.

The relative volatility and illiquidity of the Argentine securities markets may substantially limit our ADS holders’ ability to sell common shares underlying the ADSs at the price and time they desire

Investing in securities that trade in emerging markets, such as Argentina, often involves greater risk than investing in securities of issuers in the United States. The Argentine securities market is substantially smaller, less liquid, more concentrated and can be more volatile than major securities markets in the United States, and is not as highly regulated or supervised as some of these other markets. There is also significantly greater concentration in the Argentine securities market than in major securities markets in the United States. During December 2017, the ten largest Argentine companies in terms of their weight in the MERVAL index represented approximately 63.19% of its composition. Accordingly, although holders of our ADSs are entitled to withdraw the common shares underlying the ADSs from the ADS Depositary at any time, their ability to sell such shares at a price and time at which they wish to do so may be substantially limited. Furthermore, new capital controls imposed by the Central Bank could have the effect of further impairing the liquidity of the BYMA by making it unattractive for non-Argentines to buy shares in the secondary market in Argentina.

Substantial sales of our common shares or the ADSs after the global offering could cause the price of the common shares or of the ADSs to decrease

After the global offering, the existing shareholders will continue to hold a large number of shares. We, our directors, certain of our significant shareholders, including the selling shareholders, and members of senior management listed in “Management and Corporate Governance—Senior Officers”, who own in aggregate 53.29% of our outstanding common shares prior to the global offering, have agreed with the international underwriters, subject to certain exceptions, not to offer, sell, contract to sell or otherwise dispose of or hedge our shares of capital stock or ADSs or securities convertible into or exercisable or exchangeable for shares of capital stock or ADSs during the 180-day period following the date of this prospectus without the prior written consent of the representatives. See “Underwriting.” After these lock-up agreements expire, they will be able to sell their securities in the public market. Also, the Argentine government authorized the Ministry of Energy and Mining to promote the measures necessary to proceed with the sale, assignment or transfer of the equity interest owned by the Argentine government in power plants, including its interest in our Company (representing 8.25% of our

63

outstanding shares). See “Summary—The Argentine government has authorized the Ministry of Energy and Mining to proceed with the sale of their shareholdings in power plants, including their participation in us.” The market price of our common shares or the ADSs could drop significantly if they sell our common shares or the ADSs or the market perceives that they intend to sell them.

Our shareholders may be subject to liability for certain votes of their securities

Our shareholders are not liable for our obligations. Instead, shareholders are generally liable only for the payment of the shares they subscribe. However, shareholders who have a conflict of interest with us and who do not abstain from voting may be held liable for damages to us, but only if the transaction would not have been approved without such shareholders’ votes. Furthermore, shareholders who willfully or negligently vote in favor of a resolution that is subsequently declared void by a court as contrary to Argentine Corporate Law or our bylaws may be held jointly and severally liable for damages to us or to other third parties, including other shareholders.

We are an “emerging growth company” and are availing ourselves of reduced disclosure requirements applicable to emerging growth companies, which could make the ADSs or our common shares less attractive to investors

We are an EGC as defined in the U.S. Jumpstart Our Business Startups Act of 2012, and we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act and reduced disclosure obligations regarding executive compensation.

We cannot predict if investors will find the ADSs or our common shares less attractive because we may rely on these exemptions. If some investors find the ADSs or our common shares less attractive as a result, there may be a less active trading market for the ADSs or our common shares and the price of the ADSs or our common shares may be more volatile. We may take advantage of these reporting exemptions until we are no longer an EGC.

We will cease to be an EGC upon the earliest of: (1) the last day of the fiscal year during which we have revenue of US$1.07 billion or more, (2) the last day of the fiscal year following the fifth anniversary of the date of this prospects, (3) the date on which we have issued more than US$1 billion in non-convertible debt during the previous three-year period or (4) when we become a “large accelerated filer,” as defined in Rule 12b-2 under the Exchange Act.

As a foreign private issuer, we are exempt from a number of rules under the U.S. securities laws and are permitted to file less information with the Commission than a U.S. company. This may limit the information available to holders of our ADSs

We are a “foreign private issuer,” as defined in the SEC’s rules and regulations and, consequently, we are not subject to all of the disclosure requirements applicable to companies organized within the United States. For example, we are exempt from certain rules under the Exchange Act that regulate disclosure obligations and procedural requirements related to the solicitation of proxies, consents or authorizations applicable to a security registered under the Exchange Act. In addition, our officers and directors are exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act and related rules with respect to their purchases and sales of our securities. Moreover, while we expect to submit quarterly interim consolidated financial data to the Commission under cover of the Commission’s Form 6-K, we are not required to file periodic reports and financial statements with the Commission as frequently or as promptly as U.S. public companies. Accordingly, there may be less information concerning our company publicly available than there is for U.S. public companies.

As a foreign private issuer, we are not subject to certain NYSE corporate governance rules applicable to U.S. listed companies

We rely on a provision in the NYSE Listed Company Manual that allows us to follow Argentine law with regard to certain aspects of corporate governance. This allows us to follow certain corporate governance practices that differ in significant respects from the corporate governance requirements applicable to U.S. companies listed on the NYSE.

For example, we are exempt from NYSE regulations that require a listed U.S. company, among other things, to:

The market price for our common shares or ADSs could be highly volatile, and our common shares or ADSs could trade at prices below the initial offering price

The market price for our common shares or the ADSs after the global offering is likely to fluctuate significantly from time to time in response to factors including:

Volatility in the price of our common shares or the ADSs may be caused by factors outside of our control and may be unrelated or disproportionate to our operating results. In particular, announcements of potentially adverse developments, such as proposed regulatory changes, new government investigations or the commencement or threat of litigation against us, as well as announced changes in our business plans or those of competitors, could adversely affect the trading price of our common shares or the ADSs, regardless of the likely outcome of those developments or proceedings. Moreover, statements made about our Company, whether publicly or in private, may be misconstrued, particularly if read out of context. In a personal message in Spanish to an acquaintance in Argentina in December 2017, which was retransmitted without authorization, Mr. Pérès Moore, the Chairman of our Board of Directors, stated in effect that Central Puerto is a valuable company, that its stock has risen substantially, and that whether there could be upside remains to be discussed. Mr Pérès Moore did not intend to express any view about the future value of the shares, other than the uncertainty derived from factors such as the ones described in this risk factor.

Broad market and industry factors could adversely affect the market price of our common shares or ADSs, regardless of our actual operating performance. As a result, our common shares or ADSs may trade at prices significantly below the initial public offering price.

Upon becoming a registered public company and as we continue to test our internal controls, we may identify internal control issues

Our internal controls over financial reporting are not yet required to meet all of the standards contemplated by Section 404 of the Sarbanes-Oxley Act, and failure to achieve and maintain effective internal controls over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act could have a material adverse effect on our business and our common shares or the ADSs.

Because currently we do not have comprehensive documentation of our internal controls and have not yet tested our internal controls in accordance with Section 404, we cannot conclude in accordance with Section 404 that we do not have a material weakness in our internal controls or a combination of significant deficiencies that could result in the conclusion that we have a material weakness in our internal controls. We will be required to document, review and, if appropriate, improve our internal controls and procedures in anticipation of eventually being subject to the requirements of Section 404 of the Sarbanes-Oxley Act, which will require annual management assessments of the effectiveness of our internal controls over financial reporting beginning with the filing of our second annual report with the Commission and, when we cease to be an EGC, an attestation report by our independent auditors evaluating these assessments. During the course of our testing, we may identify deficiencies of which we are not currently aware.

Matters impacting our internal controls may cause us to be unable to report our financial information on a timely basis and thereby subject us to adverse regulatory consequences, including sanctions by the SEC. There also could be a negative reaction in the financial markets due to a loss of investor confidence in us and the reliability of our consolidated financial statements. Confidence in the reliability of our consolidated financial statements also could suffer if we or our independent registered public accounting firm were to report a material weakness in our internal controls over financial reporting. This could in turn limit our access to capital markets and possibly, harm our results of operations, and lead to a decline in the trading price of our common shares or the ADSs.

The protections afforded to minority shareholders in Argentina are different from and more limited than those in the United States and may be more difficult to enforce

Under Argentine law, the protections afforded to minority shareholders are different from, and much more limited than, those in the United States. For example, the legal framework with respect to shareholder disputes, such as derivative lawsuits and class actions, is less developed under Argentine law than under U.S. law as a result of Argentina’s short history with these types of claims and few successful cases. In addition, there are different procedural requirements for bringing these types of shareholder lawsuits. As a result, it may be more difficult for our minority shareholders to enforce their rights against us or our directors or controlling shareholder than it would be for shareholders of a U.S. company.

Holders of our common shares may determine not to pay any dividends

In accordance with the Argentine General Corporate Law 19,550, as amended, which we refer to as the Argentine Corporate Law, after allocating at least 5% of our annual net earnings to constitute a mandatory legal reserve, we may pay dividends to shareholders out of net and realized profits, if any, as set forth in our consolidated financial statements prepared in accordance with IFRS. The approval, amount and payment of dividends are subject to the approval by our shareholders at our annual ordinary shareholders’ meeting. The approval of dividends requires the affirmative vote of a majority of the shareholders entitled to vote at the meeting. As a result, we cannot assure you that we will be able to generate enough net and realized profits so as to pay dividends or that our shareholders will decide that dividends will be paid.

We may be a passive foreign investment company for U.S. federal income tax purposes

A non-U.S. corporation will be considered a passive foreign investment company, which we refer to as a PFIC, for U.S. federal income tax purposes in any taxable year in which 75% or more of its gross income is

66

“passive income” or 50% or more of its assets (determined based on a quarterly average) constitute “passive assets.” The determination as to whether a non-U.S. corporation is a PFIC is based upon the application of complex U.S. federal income tax rules (which are subject to differing interpretations), the composition of income and assets of the non-U.S. corporation from time to time and, in certain cases, the nature of the activities performed by its officers and employees.

Based upon our current and projected income, assets and activities, we do not expect to be considered a PFIC for our current taxable year or for future taxable years. However, because the determination of whether we are a PFIC will be based upon the composition of our income, assets and the nature of our business, as well as the income, assets and business of entities in which we hold at least a 25% interest, from time to time, and because there are uncertainties in the application of the relevant rules, there can be no assurance that we will not be considered a PFIC for any taxable year.

If we are a PFIC for any taxable year during which a U.S. Holder, as defined in “Taxation—Certain United States Federal Income Tax Considerations,” holds the ADSs or common shares, the U.S. Holder might be subject to increased U.S. federal income tax liability and to additional reporting obligations. See “Taxation—Certain United States Federal Income Tax Considerations—Passive Foreign Investment Company.” U.S. Holders are encouraged to consult their own tax advisors regarding the applicability of the PFIC rules to their purchase, ownership and disposition of the ADSs or common shares.

The requirements of being a public company may strain our resources and distract our management, which could make it difficult to manage our business

Following the completion of the global offering, we will be required to comply with various regulatory and reporting requirements, including those required by the Commission in addition to our existing reporting requirements by the CNV. Complying with these reporting and regulatory requirements will be time consuming, resulting in increased costs to us or other adverse consequences. As a public company, we will be subject to the reporting requirements of the Exchange Act, and the requirements of the Sarbanes-Oxley Act, as well as to the Argentine Capital Markets Law and CNV rules. These requirements may place a strain on our systems and resources. The Exchange Act applicable to us requires that we file annual and current reports with respect to our business and financial condition. Likewise, CNV rules require that we make annual and quarterly filings and that we comply with disclosure obligations including current reports. The Sarbanes-Oxley Act requires that we maintain effective disclosure controls and procedures and internal controls over financial reporting. To maintain and improve the effectiveness of our disclosure controls and procedures, we will need to commit significant resources, hire additional staff and provide additional management oversight. We will be implementing additional procedures and processes for the purpose of addressing the standards and requirements applicable to public companies. These activities may divert management’s attention from other business concerns, which could have a material adverse effect on our business, results of operations and financial condition.
