2. Group Strategy

PHASES OF THE COMPANY’S PLAN

The company is operating on a three-phase plan to face the COVID - 19 crisis

Mar 2020 Apr 2020 Dec 2020 Dec 2021

Phase 1

Phase 2

Phase 3

Stabilization

(reactive)

Transformation

Relaunch of the

company

Strategic changes in the structure of the Company to optimize its

operation and to be prepared for the third phase of this plan

Execution of the Financial Plan

10

3. Retain and assure critical resources

and talent

• We have reduced 10-15% of our staff.However, we identify and retain new talent

needed, as well as defining our succession

plans and contingency plans for any

undesired impact of this situation.

• Loss of 18 members of our team because ofthe pandemic. 20% of company population

confirmed to have or had COVID-19.

• Taking necessary precautions andimplementing safety protocols in all our

projects to prevent the expansion of the

situation.

• The company secured medical andeconomical support for the workers in the

event of infection.

1. Minimize the impact on companies

results on 2020

E&C: Additional costs incurred during 2Q20,

new health and operation standards for the

remaining backlog were negotiated.

Infrastructure: Present a recovery in most of its

indicators: traffic, fuel consumption or oil

price.

Real Estate: Low house income units began to

be delivered during July. However, the

deliveries have not speed up yet.

Consequently, this has been still a slow quarter

for this business unit.

All projects in the company are in execution

and implementing new safety standards. Most

of the projects are in the new maximum

production rate given the current social

distance restrictions and safety protocols.

PHASE 2: TRANSFORMATION(May 20- Dec 20)

3Q2020 Status of the Plan:

11

2. Buy time to face upcoming

financial and non-financial deadlines

• Access to credit lines or money from capitalmarket remained limited until the plea

agreement has been signed, event which

remains delayed but still possible to happen

before year end.

• Shareholders’ Meeting held on Nov 2approved a financial plan that contemplates

several scenarios based on the timing of the

plea agreement signature. The company will

seek to execute the bridge loan portion

during the next 75 days – key to avoid the

alternate scenario of selling core assets.

Revenues close to US$ 1 billion

EBITDA close to US$ 115 million

Net loss close to 12 -13 million

Financial debt close to US$ 460 million

+ Non-financial debt related to the plea agreement,

the settlement of the class action and some other

debts disclosed in last Shareholders Meeting

Total debt US$ 720 MM out of which US$

360 MM to be refinanced

Forecast 2020:

PHASE 2: TRANSFORMATION(May 20- Dec 20)

12

• Secure a bridge loan not shorter than US$ 50 MM as defined in our financialplan in the next 75 days to face different potential scenarios discussed in the

plan

• Conclude negotiations to lock amounts and terms of payment to be included inthe plea agreement and sign it if possible

• Prepare the company to resume mandatory investment plan for blocks III andIV with no external new money during 2021

PHASE 2: TRANSFORMATION(May 20- Dec 20)

Key Goals for 4Q2020:

13

New identity, purpose and

aspiration of the company

revealed

We will continue to reveal

identities and purposes in

the relevant subsidiaries

With US$ 1.9 Billion

This presentation 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 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 presentation 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: global macroeconomic conditions, including commodity prices, and economic, political and social conditions in the markets in

which we operate, particularly in Peru; major changes in Peruvian government policies at the national, regional or municipal levels,

including in connection with infrastructure concessions, investments in infrastructure and affordable housing subsidies; social conflicts in

Peru that disrupt infrastructure projects, particularly in the mining sector; interest rate fluctuations, inflation and devaluation or appreciation

of the nuevo sol in relation to the U.S. dollar (or other currencies in which we receive revenue); our ability to continue to grow our

operations, both in Peru and internationally; the level of capital investments and financings available for infrastructure projects of the types

that we perform, both in the private and public sectors; competition in our markets, both from local and international companies; our ability

to complete acquisitions on favorable terms or at all and to integrate acquired businesses and manage them effectively post-acquisition;

performance under contracts, where a failure to meet schedules, cost estimates or performance targets on a timely basis could result in

reduced profit margins or losses and impact our reputation; developments, some of which may be beyond our control, that affect our

reputation in our markets, including a deterioration in our safety record; industry-specific operational risks, such as operator errors,

mechanical failures and other accidents; availability and costs of energy, raw materials, equipment and labor; our ability to obtain financing

on favorable terms; our ability to attract and retain qualified personnel; our ability to enter into joint operations, and rules involved in

operating under joint operation or similar arrangements; our exposure to potential liability claims and contract disputes, including as a

result of environmental damage alleged to have been caused by our operations; our and our clients’ compliance with environmental, health

and safety laws and regulations, and changes in government policies and regulations in the countries in which we operate; negotiations of

claims with our clients of cost and schedule variances and change orders on major projects; volatility in global prices of oil and gas; the

cyclical nature of some of our business segments; limitations on our ability to operate our concessions profitably, including changes in

traffic patterns, and limitations on our ability to obtain new concessions; our ability to accurately estimate the costs of our projects; changes

in real estate market prices, customer demand, preference and purchasing power, and financing availability and terms; our ability to obtain

zoning and other license requirements for our real estate development; changes in tax laws; natural disasters, severe weather or other

events that may adversely impact our business; and certain other factors disclosed in our registration statement on Form F-1 on file with

the SEC.

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 presentation. In light of the risks and uncertainties described above, the future
