The gas pipeline concession of Gasoducto Sur Peruano S.A. (“GSP”) was terminated on January 24, 2017, and, as a result, we have recognized impairments with respect to our investment in and account receivables from GSP and our participation in the related construction consortium (Consorcio Constructor Ductos del Sur, or “CCDS”). Both GSP and CCDS are in the process of being liquidated. Additionally, we have recently sold certain assets and businesses, including: on April 24, 2017, the sale of our interest in Compañía Operadora de Gas del Amazonas (“COGA”); on June 6, 2017, the sale of our interest in GMD S.A. (“GMD”); on April 11, 2018, the sale of our interest in Stracon GyM S.A. (“Stracon GyM”); and, on December 4, 2018, the sale of our interest in CAM Chile S.A. (“CAM”) and CAM Servicios del Perú S.A. (“CAM Servicios”). In addition, we are in the process of marketing for sale our subsidiary Adexus S.A. (“Adexus”), which entered into Chilean bankruptcy proceedings on November 19, 2019. For more information, see “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Recent Developments (2017—2020)—Asset Sales.”

Presentation of Financial Information

Our consolidated financial statements included in this annual report have been prepared in soles and in accordance with International Financial Reporting Standards (“IFRS”) issued by the International Accounting Standards Board (“IASB”). Our annual consolidated financial statements as of December 31, 2018 and 2019 and for the years ended December 31, 2017, 2018 and 2019 have been audited by Moore Assurance S.A.S. (a member firm of Moore Global Network Limited) in accordance with the standards of the Public Company Accounting Oversight Board (United States).

Our consolidated financial statements for the year ended December 31, 2017 included in this annual report were restated in our annual report on Form 20-F for the fiscal year ended December 31, 2018. In our consolidated financial statements included in our annual report on Form 20-F for the year ended December 31, 2017, we inadvertently presented the gain on the sale of GMD under “Gain from the sale of investments” in error and, accordingly, we restated our 2017 income statement and the related notes to reflect GMD as a discontinued operation. The previously issued consolidated financial statements of the company for the 2017 fiscal year (and the related audit opinion) included in the company’s annual report on Form 20-F for the year ended December 31, 2017 should not be relied upon. For more information, see note 2.31 to our audited annual consolidated financial statements included in this annual report.

We manage our business in three segments: Engineering and Construction (E&C); Infrastructure; and Real Estate. Prior to December 31, 2017, in addition to the foregoing segments, we had a Technical Services segment. However, we transferred Concar from this segment to our Infrastructure segment beginning on April 1, 2017; on

1

June 6, 2017, we sold our interest in our former technical services subsidiary, GMD; and we are in the process of marketing for sale Adexus, our other technical services subsidiary. The historical segment financial information included in this annual report has been adjusted accordingly. For information on our results of operations by business segment, see note 7 to our audited annual consolidated financial statements included in this annual report.

As a result of the sale of GMD on June 6, 2017, we present GMD as a discontinued operation in our audited annual consolidated financial statements for the years ended December 31, 2017, 2018 and 2019. We have also reclassified our selected financial information for the years ended December 31, 2015 and 2016 included in this annual report to show GMD as a discontinued operation. In addition, (i) on December 4, 2018, we sold our interests in each of CAM and CAM Servicios, (ii) on April 11, 2018, we sold our interest in Stracon GyM, and (iii) we are in the process of marketing for sale our subsidiary Adexus. As a result, we present CAM, CAM Servicios and Stracon GyM as discontinued operations, and Adexus as an investment held for sale, in our audited annual consolidated financial statements for the years ended December 31, 2018 and 2019. We have also reclassified our consolidated financial statements for the years ended December 31, 2017, and the selected financial information for the years ended December 31, 2015 and 2016 included in this annual report to show CAM, CAM Servicios and Stracon GyM as discontinued operations and Adexus as an investment held for sale. We have also revised historical backlog data included in this annual report to exclude the presentation of entities that are presented as discontinued operations.

We requested that the staff of the U.S. Securities and Exchange Commission (the “SEC”) grant relief from the financial statement filing requirements of Rule 3-09 of Regulation S-X (“Rule 3-09”) pursuant to Section 2430 of the Division of Corporation Finance Financial Reporting Manual, with respect to our investment in GSP. The SEC has not granted our company’s waiver request and, as a result, our company was required to file with the SEC separate financial statements for GSP for 2015, 2016 and 2017, with 2016 being audited. However, it has been impracticable for our company to comply with this requirement, because the audit opinion that was issued with respect to GSP’s 2016 financial statements included a disclaimer; our company’s loss of significant influence over GSP; and GSP’s limited management as the entity is in insolvency proceedings. We believe that GSP’s financial statements would not provide additional material information to investors. However, we cannot assure you that that the SEC will not take actions against our company relating to our non-compliance, and, among other matters, in the event of a capital raise, our company may be temporarily unable to have a registration statement for a public offering of securities in the United States declared effective by the SEC. For more information, see “Item 3.D. Key Information —Risk Factors—Risks Related to Recent Developments (2017 - 2020)—Our inability to provide audited financial statements for GSP in accordance with Rule 3-09 may result in enforcement actions by the SEC or may, among other matters, cause us to be unable to complete a public offering in the United States.” For more information on GSP, see notes 5(e) and 15 to our audited annual consolidated financial statements included in this annual report.

Non-IFRS Data

In this annual report, we present EBITDA, a non-GAAP financial measure. A non-GAAP financial measure is generally defined as one that purports to measure financial performance, financial position or cash flows but excludes or includes amounts that would not be so adjusted in the most comparable IFRS measure. We present EBITDA because we believe it provides readers with a supplemental measure of the financial performance of our core operations that facilitates period-to-period comparisons on a consistent basis. Our management uses EBITDA, among other measures, for internal planning and performance measurement purposes. We believe that EBITDA is useful in evaluating our operating performance compared to other companies operating in our sectors because the calculation of EBITDA generally eliminates the effects of financing and income taxes and the accounting effects of capital spending, which items may vary for different companies for reasons unrelated to overall operating performance. EBITDA should not be construed as an alternative to net profit or operating profit, as an indicator of operating performance, as an alternative to cash flow provided by operating activities or as a measure of liquidity (in each case, as determined in accordance with IFRS). EBITDA, as calculated by us, may not be comparable to similarly titled measures reported by other companies. For our definition of EBITDA and a reconciliation of EBITDA to the most directly comparable IFRS financial measure, see “Item 3.A. Key Information—Selected Financial Data—Non-GAAP Financial Measure and Reconciliation.”

Currency Translations

Our consolidated financial statements are prepared in soles. For a description of our translation of amounts in currencies other than soles in our consolidated financial statements, see note 2.4 to our audited annual consolidated financial statements included in this annual report.

We have translated some of the soles amounts contained in this annual report into U.S. dollars and some U.S. dollars amounts contained in this annual report into soles, for convenience purposes only. Unless otherwise indicated or the context otherwise requires, the rate used to translate soles amounts to U.S. dollars and U.S. dollars amounts into soles was S/3.317 to US$1.00, which was the exchange rate reported for December 31, 2019 by the Peruvian Superintendency of Banks, Insurance and Private Pension Fund Administrators (Superintendencia de Banca, Seguros y AFPs, or “SBS”). We present our backlog in U.S. dollars. For contracts denominated in soles or other local currencies, amounts have been converted into U.S. dollars based on the exchange rate published by the SBS on December 31 of the corresponding year. When we present our ratios of backlog and revenues in this annual report, we similarly convert our revenues, which are reported in soles, into U.S. dollars based on the exchange rate reported for December 31 of the corresponding year. For conversions of macroeconomic indicators (particularly in “Item 5.D. Operating and Financial Review and Prospects—Trend Information” in this annual report), average annual exchange rates for the currencies of each of the countries addressed are used. The Federal Reserve Bank of New York does not report a noon buying rate for soles. The U.S. dollar equivalent information presented in this annual report is provided solely for convenience of the reader and should not be construed as implying that the soles or other currency amounts represent, or could have been or could be converted into, U.S. dollars at such rates or at any other rate.

Rounding

Certain figures included in this annual report have been subject to rounding adjustments. Accordingly, figures shown as totals in certain tables may not be arithmetic aggregations of the figures that precede them.

Backlog

This annual report includes our backlog for our Engineering and Construction (E&C), Infrastructure and Real Estate segments. We do not include backlog in this annual report in our Infrastructure segment for: (i) our Norvial toll road concession because its revenues from the concession are derived from toll fees charged to vehicles using the highway, and, as a result, such revenues are dependent on vehicular traffic levels; and (ii) our Energy line of business because: (a) our revenues from hydrocarbon extraction services are dependent on the amounts of oil and gas we produce and market prices, which fluctuate significantly; (b) our revenues from our gas processing plant are dependent on the amount of gas we process and market prices for natural gas liquids, which fluctuate significantly; and (c) our revenues from our fuel storage terminal operation partially depend on the volume of fuel stored and dispatched. When we present backlog on a segment basis, we do not include eliminations that are included in our consolidated backlog. Backlog is not a measure defined by IFRS, and our methodology for determining backlog may not be comparable to the methodology used by other companies in determining their backlog. Backlog is not audited. We have revised historical backlog data included in this annual report to exclude the presentation of entities that are presented as discontinued operations. For our definition of backlog, see “Item 4.B. Information on the Company—Business Overview—Backlog.” See also “Item 3.D. Key Information—Risk Factors—Risks Related to our Company—Our backlog and our ratio of historical backlog to revenues may not be reliable indicators of future revenues or profit.”

The GSP gas pipeline concession was terminated on January 24, 2017, which had a significant impact on our backlog for our E&C and our consolidated backlog. For more information, see “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Recent Developments (2017—2020)—Termination of the Gasoducto Sur Peruano Concession.”

Reserves Estimates

This annual report includes our estimates for proved reserves in Blocks I and V, where GMP provides hydrocarbon extraction services to, and Blocks III and IV, where GMP extracts hydrocarbon under license agreements with, Perupetro S.A. (“Perupetro”). These reserves estimates were prepared internally by our team of engineers and

3

have not been audited or reviewed by any independent external engineers. For further information on these reserves estimates, see “Item 3.D. Key Information—Risks Related to Our Company—Additional Risks Related to our Infrastructure Business” and “Item 4.B. Information on the Company—Business Overview—Infrastructure—Principal Infrastructure Lines of Business—Energy—Oil and Gas Production.”

Market Information

We make estimates in this annual report regarding our competitive position and market share, as well as the market size and expected growth of the engineering and construction, infrastructure and real estate services industries in Peru and elsewhere in Latin America. We have made these estimates on the basis of our management’s knowledge and statistics and other information, which we believe to be the most recently available as of the date of this annual report, from government agencies, industry professional organizations, industry publications and other sources. While we believe these estimates to be accurate as of the date of this annual report, we have not independently verified the data from third-party sources and our internal data has not been verified by any independent source. We paid Great Place to Work ^® Institute, a human resources consulting, research and training firm, for our employees to participate in their market survey referenced in this annual report (Copyright ^© 2019 Great Place to Work ^® Institute, Inc. All rights reserved.). In this annual report we present gross domestic product (“GDP”) both on a nominal and real basis. Real GDP is nominal GDP adjusted to exclude the effect of inflation. Unless otherwise indicated, references to GDP are to real GDP.

Measurements and Other Data

In this annual report, we use the following measurements:

In this annual report, we use the term “accident incidence rate” with respect to our E&C segment, which is calculated as the number of injuries divided by the total number of hours worked by all full-time employees of our E&C segment during the relevant year divided by 200,000 (which reflects 40 hours worked per week in a 50-week year by 100 equivalent full-time workers).

Forward-Looking Statements

This annual report contains forward-looking statements. Forward-looking statements convey our current expectations or forecasts of future events. These statements involve known and unknown risks, uncertainties and other factors, including those listed under “Item 3.D. Key Information—Risk Factors,” which may cause our actual results, performance or achievements to differ materially from the forward-looking statements that we make.

Forward-looking statements typically are identified by words or phrases such as “may,” “will,” “expect,” “anticipate,” “aim,” “estimate,” “intend,” “project,” “plan,” “believe,” “potential,” “continue,” “is/are likely to,” or other similar expressions. Any or all of our forward-looking statements in this annual report may turn out to be inaccurate. Our actual results could differ materially from those contained in forward-looking statements due to a number of factors, including, among others:

The forward-looking statements in this annual report represent our expectations and forecasts as of the date of this annual report. These statements are intended to qualify for the safe harbors from liability provided by Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Except as required by law, we undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, after the date of this annual report. In particular, the COVID-19 pandemic, and governments’ extraordinary measures to limit the spread of the virus, are disrupting economic activity and the industries in which we operate, and consequently adversely affecting our business, results of operation and financial condition and, as conditions are recent, uncertain and changing rapidly, it is difficult to predict the full extent of the impact that the pandemic will have on our company.

The following selected financial data as of December 31, 2018 and 2019 and for the years ended December 31, 2017, 2018 and 2019 have been derived from our audited annual consolidated financial statements included in this annual report. The following selected financial data as of December 31, 2015, 2016 and 2017 and for the years ended December 31, 2015 and 2016 have been derived from our audited annual consolidated financial statements not included in this annual report. Our annual consolidated financial statements for the years ended December 31, 2017, 2018 and 2019 have been audited by Moore Assurance S.A.S. (a member firm of Moore Global Network Limited) in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our consolidated financial statements for the year ended December 31, 2017 included in this annual report were restated in our annual report on Form 20-F for the year ended December 31, 2018.

Non-GAAP Financial Measure and Reconciliation

In this annual report, we present EBITDA, a non-GAAP financial measure. A non-GAAP financial measure is generally defined as one that purports to measure financial performance, financial position or cash flows but excludes or includes amounts that would not be so adjusted in the most comparable IFRS measure. We define EBITDA as net profit plus: financial (expense) income, net; income tax; and depreciation and amortization.

We present EBITDA because we believe it provides readers with a supplemental measure of the financial performance of our core operations that facilitates period-to-period comparisons on a consistent basis. Our management uses EBITDA, among other measures, for internal planning and performance measurement purposes. We believe that EBITDA is useful in evaluating our operating performance compared to that of other companies operating in our sectors because EBITDA eliminates the effects of financing and income taxes and the accounting effects of capital spending, which items may vary for different companies for reasons unrelated to overall operating performance. EBITDA should not be construed as an alternative to net profit or operating profit, as an indicator of operating performance, as an alternative to cash flow provided by operating activities or as a measure of liquidity (in each case, as determined in accordance with IFRS). EBITDA, as calculated by us, may not be comparable to similarly titled measures reported by other companies. The following table sets forth the reconciliation of our net profit to EBITDA on a consolidated basis.

The following table shows a reconciliation of the EBITDA for our three segments, Parent company operations and intercompany eliminations:

The following tables set forth the reconciliation of our net profit to EBITDA for each of our business segments and certain of our lines of business or subsidiaries within these segments. The effects of the termination of the GSP gas pipeline concession on our results of operations and financial condition for 2016 are reflected in Corporate (the Parent Company Operations) and, with respect to the related construction consortium (CCDS), in our E&C segment. Beginning on April 1, 2017, we transferred Concar from our Technical Services segment to our former Infrastructure segment. This change does not impact our consolidated financial results.

Risks Related to Recent Developments (2017—2020)

The ongoing COVID-19 pandemic and government measures to contain the spread of the virus are disrupting economic activity in the countries where we operate and adversely affecting our business, results of operations and financial condition.

The recent outbreak of the Novel Coronavirus 2019 (COVID-19) pandemic, which has been declared by the World Health Organization to be a “public health emergency of international concern,” has spread across the world since the end of 2019. The virus has spread significantly in Latin America to date, and we cannot assure you that the virus will not spread more widely in the region. In such event, the countries where we operate are likely to have less resources to address the health care effects of the pandemic. In response, countries around the world—including Peru as well as Chile and Colombia—have adopted extraordinary measures to contain the spread of COVID-19, including imposing travel restrictions, requiring closures of non-essential businesses, establishing restrictions on public gatherings, instructing residents to practice social distancing, issuing stay-at-home orders, implementing quarantines and similar actions. Depending on how the spread of the virus continues to evolve, governments may extend these measures for longer periods.

The COVID-19 pandemic and these government measures have significantly increased economic uncertainty and are likely to cause a global recession. Moreover, the impact of the pandemic on economic activity has been sudden and severe, and we cannot predict the extent to which economies in the countries where we operate will ultimately be impacted. Even if the initial outbreaks of COVID-19 subside, we cannot predict whether subsequent outbreaks will reoccur, or whether governments will implement longer-term measures that continue to affect economic activity and capital investment levels. As a result, the negative impact of COVID-19 may continue well beyond the containment of the virus. In response to the sudden decline in economic activity, governments around the world, including in Latin America, have announced large stimulus programs to assist families and businesses. However, we cannot assure you that these programs will be sufficient to reactivate economy activity; moreover, the governments in the countries where we operate are likely to have less resources to stimulate their local economies.

The COVID-19 pandemic is significantly and adversely affecting our business, results of operations and financial condition. From mid-March through the end of May 2020, substantially all of our engineering and construction and real estate projects were mandatorily shut down. Although certain projects are gradually resuming, we cannot assure you when we will be able to resume work on our projects in full. Our infrastructure operations, which have for the most part been declared essential businesses, have continued; however, certain of our infrastructure businesses have been adversely affected, in particular, by the sharp decline in traffic volumes and oil and gas prices (also due to the

14

dispute in March among OPEC member countries). Our results and operations of the first quarter of 2020 were adversely impacted by the pandemic. We expect that our results of operations for the second quarter of 2020 will be significatively more impacted, as adverse conditions have persisted for a longer period during the second quarter. We are evaluating measures to reduce our expenses and preserve liquidity. However, depending on how long current conditions persist and unless we are able to benefit from government stimulus programs, the pandemic is likely to have a material adverse effect on our business, results of operation and financial condition.

Our reputation has been adversely affected by our association with Odebrecht’s affiliates in Peru

We participated in six construction and operation of infrastructure projects in Peru with affiliates of Odebrecht during the period from 2005 to 2017. Our reputation has been adversely affected as a result of the plea agreements and criminal convictions of Odebrecht and certain key persons related to Odebrecht in connection with corruption, money laundering and criminal organization. Peruvian authorities have initiated criminal investigations into the dealings of Odebrecht’s affiliates in Peru, the scope of which include certain consortia in which we participated. Moreover, as a result, our company and certain of our former directors and senior management are the subject of criminal investigations relating to corruption allegations. These investigations are ongoing.

In January 2019, Odebrecht executed a settlement and cooperation agreement with the Peruvian government regarding several infrastructure projects in the country, including certain projects in which we participated. Under the agreement, Odebrecht has agreed to pay compensation to the Peruvian government over the course of several years and to cooperate with, and provide evidence to, prosecutors in connection with ongoing investigations by the Peruvian government. Former senior officers of Odebrecht’s affiliate in Peru have indicated to Peruvian prosecutors that certain of our former directors and senior management were aware that Odebrecht had made corrupt payments to government officials in connection with certain projects in which we participated.

In December 2019, we entered into a preliminary settlement and cooperation agreement with the Peruvian anticorruption prosecutor and the ad hoc Peruvian state counsel in respect of investigations relating to past projects in which the company participated with Odebrecht and investigations relating to an alleged participation in the “construction club”. The terms of the preliminary settlement and cooperation agreement are confidential in accordance with Peruvian law and under discussion with Peruvian authorities.

Our reputation is a key factor in our clients’ evaluation of whether to engage our services, key industry players’ willingness to partner with us, financial institutions’ willingness to provide us credit, and recruiting and retaining talented personnel to our company. The impact on our business reputation related to our association with Odebrecht and the alleged actions of our former board members and senior management has had, and is likely to continue to have, a material adverse effect on our business, financial condition and results of operations. The outcome of the ongoing investigations and settlement discussions, any new charges or news reports containing new allegations against the company, or other similar developments, could further damage the reputation of the company.

Investigations regarding potential corruption or other illegal acts could have a material adverse effect on our business, financial condition and results of operations

Our company and certain of our subsidiaries, and certain of our former directors and senior management, have been charged in connection with criminal and civil investigations relating to certain of our projects in connection with our association with Odebrecht and in connection with our alleged participation in what is referred to as the “construction club.”

In connection with investigations relating to the IIRSA South project concession (tranche II), the Peruvian criminal prosecutor moved to charge our company and our construction subsidiary, GyM, as criminal defendants in connection with the project. In response, the Peruvian First National Preparatory Investigation Court (Primer Juzgado de Investigación Preparatoria Nacional) notified us of its decision to formally include our company and GyM in its criminal investigation. We appealed the court’s decision and, in June 2018, the First Court of Appeals of the Superior Court of Lima revoked the judicial order that indicted our company and GyM, among other corporate defendants, in the criminal investigation on charges of collusion and other crimes and rejected the petition, without prejudice, made by the prosecutor to incorporate both companies in the aforementioned process. Nevertheless, in February of 2020, we were notified that the criminal prosecutor had filed a new motion to bring criminal charges against our company and GyM in connection with the IIRSA South project concession (tranche II). We cannot predict the outcome of this motion.

15

Separately, in connection with these investigations, in December 2018, the Peruvian First National Preparatory Investigation Court resolved to include our company and GyM as civilly-responsible third parties in the investigations related to the IIRSA South project concession (tranche II) and GyM as a civilly-responsible third party in the investigations related to Tranches 1 and 2 of the Lima Metro. These proceedings are ongoing.

Peruvian prosecutors have included José Graña Miró Quesada, a shareholder and the former Chairman of our company, in an investigation for the crime of collusion, and Hernando Graña Acuña, a shareholder, a former board member of our company and former chairman of our subsidiary GyM, for the crime of money laundering against the Peruvian government, each in connection with the IIRSA South project concession (tranche II), in which we participated with Odebrecht. Gonzalo Ferraro Rey, the former Chief Infrastructure Officer of our company, has also been included in an investigation for the crime of money laundering in connection with the same project. In addition, José Graña Hernando Graña, as well as Juan Manuel Lambarri, the former chief executive officer of our subsidiary GyM, have been charged in connection with Tranches 1 and 2 of the Lima Metro project. In August 2019, José Graña indicated in public statements to the media that he and Hernando Graña had initiated a process of plea bargaining with Peruvian prosecutors in respect of multiple projects in which our company participated with Odebrecht and in respect of the alleged “construction club.” According to José Graña’s public statements, in the plea bargaining process, both he and Hernando Graña are cooperating with the Peruvian prosecutor, which may include providing information related to wrongdoing or knowledge of improper behavior while they were at the company. However, given the confidential nature of these proceedings, the reported information is limited and difficult to verify. We cannot assure you what they will ultimately say to the government, or that their statements will not adversely affect the company’s business.

A conviction of corruption or settlements with government authorities could lead to criminal and civil fines as well as penalties, sanctions, injunctions against future conduct, profit disgorgement, disqualifications from directly and indirectly engaging in certain types of business, the loss of business licenses or permits, debarment from contracting or from participating in bidding processes with the Peruvian government, or other restrictions. Moreover, our alleged involvement in corruption investigations, and any findings or admissions of wrongdoing in such investigations, could further damage our reputation and have a material adverse impact on our ability to compete for business. In addition, such investigations may affect the company’s ability to secure financing in the future. Furthermore, investigations could continue to divert management’s attention and resources from other issues facing our business.

In May 2018, Peruvian Supreme Decree No. 096-2018-EF set forth guidelines to determine the value of assets to be put in trust to guarantee eventual compensation to the Peruvian government that is required for companies that have been partners of companies that have been, or whose officers or representatives have been, convicted of, or have admitted to, corruption, money-laundering or similar crimes, which includes our company and our subsidiary GyM. Following discussions with the Peruvian government, in February 2019, we established a trust in favor of the Peruvian government in respect of any liabilities arising from Tranches 1 and 2 of the Lima Metro project and Tranche II of the IIRSA project, to which we assigned shares of our subsidiary GMI, which is estimated to be worth approximately US$23.4 million (S/79.1 million). We cannot assure you that the Peruvian government will not claim the assets set forth in this trust or require that our company place additional assets in trust, nor can we assure you that these assets will fully satisfy any eventual obligations we may have to the Peruvian government.

Management has estimated the value of the company’s contingencies to be approximately US$84.4 million (S/279.8 million), and taking into account the net present value, established a provision in the company’s financial statements in the amount of US$46.6 million (S/153.9 million). This includes amounts in respect of probable liabilities arising from the investigations of Tranche II of the IIRSA project, Tranches 1 and 2 of the Lima Metro project, the GSP project and the “construction club” investigation (described below). We cannot provide assurance that our liability will not exceed the amount estimated by management and provisioned for in the financial statements of the company. Furthermore, if the company is further charged in connection with wrongdoing in respect of other projects, this contingent amount could increase significantly.

16

We cannot assure you that the scope of the foregoing proceedings will not be expanded to incorporate other projects in which we have been involved, that our company will not be included in other investigations or proceedings as a criminal defendant or civilly-responsible third party in Peru or elsewhere, or that other of our former or current directors and senior management will not be included in the foregoing proceedings. We continue to evaluate alternatives to resolving ongoing investigations against our company and our subsidiary GyM, including the negotiation of a settlement and cooperation agreement with Peruvian authorities. However, we cannot assure you that these investigations will be resolved in a manner that is favorable to our company.

INDECOPI and Peruvian prosecutors have initiated investigations alleging that certain construction companies in Peru, including our company, colluded to receive public contracts

The Peruvian National Institute for the Defense of Free Competition and the Protection of Intellectual Property (“INDECOPI”) initiated in 2017 investigations regarding allegations that certain construction companies in Peru, including our subsidiary GyM, colluded as a “construction club” to receive public contracts. In February 2020, INDECOPI initiated an administrative proceeding against several construction companies, including our subsidiary GyM, aiming to impose civil fines on the investigated companies.

Separately, in December 2018, GyM was formally included as a civilly-responsible third party, along with eleven other construction companies, in the criminal investigation conducted by a Peruvian public prosecutor based on facts similar to those under investigation by INDECOPI. In December 2019, the prosecutor criminally charged GyM and another of our subsidiaries, CONCAR, and other companies in the construction sector in Peru, as well as a former director and senior management of our company, with collusion and other alleged crimes. As described above, the company’s management has made estimates, and established provisions, in the company’s audited consolidated financial statements for the investigations in respect of the company and its subsidiaries, including in respect of the company’s alleged participation in what is referred to as the “construction club”. We cannot provide assurance that our liability will not exceed the amount estimated by management and provisioned for in the financial statements of GyM and CONCAR. Furthermore, if GyM, CONCAR or any other subsidiary of the company is further charged in connection with wrongdoing in respect of other projects, this contingent amount could increase significantly.

We cannot assure you that any of our company’s other current or former directors or senior management will not be included in these investigations or proceedings in the future, nor can we predict the outcome of any such investigations or proceedings, the timing thereof or how they may impact our business, financial condition and results of operations. We also cannot predict whether prosecutors or INDECOPI will bring additional investigations or proceedings in the future. We continue to evaluate alternatives to resolving ongoing investigations against our subsidiaries GyM and CONCAR, including the negotiation of a settlement and cooperation agreement with Peruvian authorities. However, we cannot assure you that these investigations will be resolved in a manner that is favorable to our company.

A conviction of corruption or settlements with government authorities could lead to criminal and civil fines as well as penalties, sanctions, injunctions against future conduct, profit disgorgement, disqualifications from directly and indirectly engaging in certain types of business, the loss of business licenses or permits, debarment from contracting or from participating in bidding processes with the Peruvian government, or other restrictions.

We are currently negotiating a settlement and cooperation agreement with Peruvian authorities in connection with the criminal investigations against our company

In December 2019, we entered into a preliminary settlement and cooperation agreement with the Peruvian anticorruption prosecutor and the ad hoc Peruvian state counsel in respect of investigations relating to past projects in which the company participated with Odebrecht and investigations relating to an alleged participation in the “construction club”. The terms of the preliminary settlement and cooperation agreement are confidential in accordance with Peruvian law and under discussion with Peruvian authorities.

Although in the preliminary settlement and cooperation agreement, the Peruvian government undertook to enter into a final settlement and cooperation agreement within sixty business days, we have not reached a final agreement, and the parties continue to discuss the terms of the settlement. Although we expect to reach a final

17

agreement with the government, we cannot guarantee that the government will execute the agreement within a reasonable time frame or at all, nor can we guarantee that any final settlement and cooperation agreement will be executed on terms favorable to the company. In particular, we cannot provide assurances that the government will not require compensation in an amount materially greater than the amount we have estimated and provisioned; that our company will be able to pay any compensation required pursuant to the terms of any final settlement and cooperation agreement; or a final settlement and cooperation agreement will not contain measures that restrict the company’s business in the future, including limitations on the company’s ability enter into contracts with the Peruvian government. We also cannot guarantee what impact any settlement and cooperation agreement, which may require admission of wrongdoing, will have on our reputation.

A class action civil lawsuit in the United States may adversely affect our company

A class action civil lawsuit was filed in 2017 against our company and certain of our former directors and former and current executive officers in the United States. In February 2020, we executed a term sheet with the plaintiffs that provides the general terms and conditions for a final settlement agreement. The term sheet stipulates a settlement amount of US$20 million plus interest after a certain time period. The company recorded provisions of US$15 million as of December 31, 2019, and the remaining US$5 million is expected to be covered by the company’s D&O insurance. It is not certain whether the negotiation of a final settlement agreement will be successful, and if so, whether any such agreement will be approved by the court. In such case, we would expect the lawsuit to resume.

If the lawsuit continues to be litigated, we cannot assure you that our position will prevail. If our position does not prevail, the lawsuit may have a material adverse effect on our business, financial condition and results of operations.

There is substantial uncertainty with regard to the amount, timing and manner in which the payment for the termination of the GSP gas pipeline concession will be paid

There is substantial uncertainty with regards to the payment contemplated under the GSP gas pipeline concession contract as a result of the termination of the gas pipeline concession, including with respect to the amount, timing and manner in which the payment will be made, or if it will be made at all.

Although the concession contract provides that payment must be made within one year of termination, the Peruvian Ministry of Energy and Mines has not made payment or, to our knowledge, initiated the payment process or the auction process for a new concessionaire. As a result, after the six-month period mandated by the concession contract for the parties to discuss the matter, in October 2019, we asserted our rights against the Peruvian government by filing a request for arbitration before the International Centre for Settlement of Investment Disputes. However, in December 2019 we withdrew our request for arbitration, as required by Peruvian authorities under the preliminary settlement and cooperation agreement we entered into with Peruvian anticorruption prosecutor and the ad hoc Peruvian state counsel.

As of the date of this annual report, we are analyzing available contractual and legal options to recover as a creditor of GSP. However, we cannot guarantee that any of these options will be successful, or that we will be able to recover all or any of the amounts owed to the company as a result of the termination of the GSP gas pipline concession on a timely basis, or at all. Failure to receive the expected payment on a timely basis, or at all, would have a material adverse effect on our business, financial condition and results of operations.

We have made certain estimates in our consolidated financial statements with respect to the expected payment for the termination of the GSP contract. As of December 31, 2019, we fully impaired the remaining amount of our investment in GSP. However, we maintain S/544 million (US$164 million) in long-term account receivables as a creditor of GSP.

Our inability to provide audited financial statements for GSP in accordance with Rule 3-09 may result in enforcement actions by the SEC or may, among other matters, cause us to be unable to complete a public offering in the United States

We have been unable to provide certain financial statements of GSP that are required by Rule 3-09 to be included in our company’s annual report. Under Rule 3-09, we are required to present or generate financial statements of GSP as of December 31, 2015 and for the period from November 2, 2015 to December 31, 2015, as of and for the year ended December 31, 2016 and as of and for the year ended December 31, 2017, with the financial statements of GSP as of and for the year ended December 31, 2016 audited in accordance with the standards of the Public Company Accounting Oversight Board. It is currently impracticable for our company to comply with this requirement, because the audit opinion that was issued with respect to GSP’s 2016 financial statements included a disclaimer, our company’s loss of significant influence over GSP, and GSP’s limited management as the entity is in insolvency proceedings.

We believe that the information presented by separate financial statements of GSP would not provide to our company’s investors additional material information not already included in our company’s own consolidated financial statements included in this annual report. As a result, we do not believe that the omission of those financial statements will have a material impact on a reader’s understanding of our financial condition or results of operations. Nevertheless, we requested a waiver from the SEC from the requirement to file the consolidated financial statements of GSP described above, and the SEC has not granted our waiver request.

As a result, we are currently not fully compliant with our reporting requirements with the U.S. Securities Exchange Act of 1934 (the “Exchange Act”). The SEC may impose penalties or otherwise take action against our company. In addition, the SEC may not declare effective any registration statement that we file that requires the financial statements under Rule 3-09 to be included. If, as a result, we are unable to complete a registered offering, our ability to access the public capital markets in the United States would be impaired. Furthermore, the Rule 144 safe harbor for certain sales of our ADSs in the United States is currently unavailable.

We were in default under certain of our debt instruments during 2017, 2018 and 2019, and we cannot assure you that we will not be in default under our debt instruments in the future, or that we will be able to obtain additional waiver in the event of any future defaults

In 2019, our subsidiary Adexus entered into Chilean bankruptcy proceedings to restructure its outstanding indebtedness and, as a result, we were in default under our loan agreement with CS Peru Infrastructure Holdings LLC. We received a waiver for the default on February 28, 2020. As a result, this indebtedness of US$35 million was recorded as a current liability as of December 31, 2019, of which US$10 million was repaid at the time of the waiver. Also during 2019, our construction subsidiary GyM was under a continuing default under the Financial Stability Framework Agreement with respect to its failure to comply with certain ratios between Tranche A (client invoices) and Tranche B (client provisions). No event of default was formally notified to GyM by the lenders, and GyM procured a waiver from the lenders in July 2019. In addition, during the years 2017 and 2018 we were in default under certain of our debt instruments, including due to: delays in delivering audited financial statements; defaults with respect to certain financial ratio and other covenants; and delays in paying certain amounts outstanding. We procured waivers from our creditors under such instruments.

We cannot assure you that we will not breach the covenants under these or other of our debt instruments in the future and, in such event, that we would be able to obtain the required waivers from our creditors. Failure to successfully obtain waivers could force us to precipitate the sale of assets, including on unfavorable terms, to repay these debt instruments. Moreover, if we are not able to renegotiate the terms of any debt instruments in which we are in default, or repay them promptly, our ability to obtain financings, including performance guarantees or similar financings required under many of our business contracts, would be impaired, which may have a material adverse effect on our business, financial condition and results of operations.

We may be unable to access financing that we need to operate our business on favorable terms or at all

Due to uncertainty relating to the investigations of our company, our creditors and other banks operating in the Peruvian market have placed restrictions on our ability, and the ability of other construction companies, to acquire future credit lines or other financings. We cannot assure you that we will be able to obtain new financings in the future on favorable terms or at all. We may encounter difficulties in obtaining performance bonds or credit support that we require to secure, among other things, bids, advance payments and performance for our projects.

19

Our ability to obtain financings will also depend in part upon prevailing conditions in credit and capital markets, which are beyond our control. Emerging markets have been affected by changes in the U.S. monetary policy, resulting at times in a withdrawal of investments and increased volatility in the value of their currencies. If interest rates rise significantly in the United States, emerging market economies, including Peru, could find it more difficult and expensive to borrow capital and refinance existing debt. Higher interest rates globally or in Peru would in turn impact our costs of funding.

Currently, volatility and instability due to the ongoing COVID-19 pandemic and government measures to contain the spread of the virus also has, and may continue to, negatively affect the general willingness of lenders to extend credit. At the same time, the COVID-19 pandemic has also put further pressure on our liquidity needs, including for short-term working capital; from mid- March through the end of May, substantially all of our engineering and construction and real estate projects have been mandatorily shut down, and, although work on many of our projects will begin to resume generally, we cannot assure you when we will be able to resume work on our projects in full.

An inability to procure adequate financing or credit on favorable terms or all could have a material adverse effect on our business, financial condition and results of operation.

We may not be able to sell assets on favorable terms or at all

As part of our strategic action plan in response to the termination of the GSP gas pipeline concession, our board of directors approved the sale of certain non-strategic assets, in order to raise funds to make payments in respect of debt related to the termination of the GSP gas pipeline concession. In 2017 and 2018 we undertook multiple divestitures. In addition, we continue marketing for sale our subsidiary Adexus. Moreover we are also evaluating the sale of additional assets, including part of our land bank, which we do not consider to be strategic to our business, to meet our liquidity needs. However, we cannot assure you that we will be able to continue to sell assets on favorable terms or at all. If we are not able to sell assets on a timely basis, our ability to address our liquidity needs may be adversely affected. Conversely, if we sell significant assets, our business and results of operations will be diminished.

We may be subject to takeover transactions, and we cannot assure you that any such transaction, if it were to occur, would be favorable to our shareholders.
