Proyecto Peru allowed the company to develop new business opportunities providing maintenance services to more than 4,000 km of public roads in Peru. The company's revenue in the operation and maintenance of infrastructure assets is generated either from fees the company charge to Norvial, Survial, Canchaque, Chinchaypujio and the Line 1 to operate and maintain the company's concessions or from government payments through maintenance service contracts the company has been awarded. The company provides the following road operation and maintenance services: Routine Maintenance. These services aim to preserve roads through ongoing maintenance, including road demarcation, cleaning, drainage, road fissure treatment which seals cracks in roads to prevent water infiltration, slurry sealing and micro-paving which seals asphalt to prevent aging and improve resistance to water and surface wear. Periodic Maintenance. These services entail activities that are performed periodically, intended to prevent the occurrence or exacerbation of defects, conserve the structural integrity of roads and correct major defects. Emergency Maintenance. This maintenance work is performed whenever the need arises, such as when natural disasters damage road surfaces. The company also administers toll stations and weighing stations, offer road patrolling services, operate assistance call centers and provide emergency medical services. The operation and maintenance services the company provides to the Lima Metro aim to preserve the mass transit system through ongoing maintenance, including cleaning of the trains and stations and providing train operators, among other services. With respect to operation and maintenance contracts with the Peruvian government, the company obtains new contracts through public bidding. With respect to contracts with the company's Infrastructure segment, the company participates in direct negotiation. Contract length typically ranges from three to five years. Energy The company operates three producing oil fields and five multiple fuel storage facilities under long-term government contracts, and the company owns a gas processing plant. The company's strategy is to develop the oil reserves of Block III and IV, to consolidate the company's storage business, and to look for new opportunities in the natural gas business. Through the company's Energy segment, the company has participated with 8% of the oil production, 1.5% of the liquefied petroleum gas (LPG) production and 19% of the fuel dispatch within Peru during 2022, according to the Ministry of Energy and Mines of Peru (MINEM). The company operates three energy businesses within the company's Energy segment: Exploration and Production: The company has been operating and extracting oil from four onshore fields (Block I, Block III, Block IV and Block V) located in the provinces of Talara and Paita in northern Peru. The company had two hydrocarbon extraction service contracts with Perupetro, the Peruvian entity responsible for the administration and supervision of all exploration and production contracts in Peru, under which the company has been operating two oil producing fields, Block I which expired on December 26, 2021 and Block V that will expire in October 2023. In addition, the company has two long-term license contracts with Perupetro, a state-owned oil and gas company, for two other blocks, Block III and IV, which started operations in April 2015 and oil production from these blocks is sold to Petroperu. During 2022, the oil production of the company's four blocks was approximately 3,063 bbl per day on average. Natural Gas: The company owns and operates a natural gas processing plant located in northern Peru, which processes and fractions natural gas, sells the liquids and delivers dry gas to a gas-fired power generation company under a long-term processing and fractionation agreement.

Oil and Gas Production The company has been operating and extracting oil from four mature fields (Blocks I, III, IV and V) located in the provinces of Talara and Paita in northern Peru. Two of these fields, Blocks I and V, have been operated under service contracts under which the company provides hydrocarbon extraction services to Perupetro. Hydrocarbons extracted from these two blocks belong to Perupetro, which in turn pays the company, once a month, a variable fee per barrel of extracted hydrocarbons. This extraction fee is based on a basket of international crude prices and the level of production. The service contract of Block I expired on December 26, 2021 and the Block V contract will expire on October 2023. The other two fields, Blocks III and IV, are operated under long-term license contracts with Perupetro. The hydrocarbons extracted are owned by the company's subsidiary UNNA Energía, who sells the oil to Petroperu based on the average prices of three international crude oil prices: Fortis, Suez Blend and Oman Blend crudes. UNNA Energía pays royalties, to Perupetro, calculated in accordance with a contractual formula that accounts for price, volume, income and expenses of each block. The company's activities are focused on proved reserves development and production and are conducted in mature oil fields, which have been producing oil for over 100 years in the case of Block I, over 95 years in the case of Block III, over 95 years in the case of Block IV, and over 50 years in the case of Block V. The company's activities in these fields bear limited exploration risk. Block I: The company operated and extracted oil and natural gas from Block I under a 30-year hydrocarbon extraction service contract with Perupetro, which was extended for an additional 10-year term and expired on December 26, 2021. Average daily production during 2021 was 537 barrels of crude oil. The company operated wells using various oil extraction systems and operated a network of production batteries and pipelines to collect, measure and deliver oil in a control point close to the Talara refinery. The field is located in the province of Talara, department of Piura, in northern Peru, approximately five miles from the Talara refinery, the second largest refinery in the country.

Average daily production during 2022 was 627 barrels of crude oil. The company operates wells using various oil extraction systems and operates a network of production batteries and pipelines to collect, measure and deliver oil in a control point close to the Talara refinery, which purchases the oil according to a contract based on an average price of three international crude oil prices: Fortis Blend, Suez Blend and Oman crudes, as adjusted by certain factors. The field is located between the provinces of Talara and Paita, department of Piura, in northern Peru, approximately 43 miles from the Talara refinery. Block IV: The company operates and extracts oil and natural gas from Block IV under a 30-year license agreement with Perupetro, which expires in April 2045. Average daily production during 2022 was 2,331 barrels of crude oil. The company operates wells using various oil extraction systems and operates a network of production batteries and two pipelines to collect, measure and deliver oil in a control point close to the Talara refinery, which purchases the oil according to a contract based on an average price of three international crude oil prices: Fortis Blend, Suez Blend and Oman crudes, adjusted for costs related to hydrocarbon transportation. The field is located in the province of Talara, department of Piura, in northern Peru, approximately 21 miles from the Talara refinery. Block V: The company operates and extracts oil and natural gas from Block V under a 30-year hydrocarbon extraction service contract with Perupetro, which was extended for an additional 10-year term and expires in October 2023. Average daily production during 2022 in this field was 105 barrels of crude oil. The company operate 46 wells in this field using various oil extraction systems. The Block V field is located in the province of Los Órganos, department of Piura, Peru, close to the border with Ecuador. Block V has been producing oil since the 1950s. For Block V, the company is entitled to a variable fee paid by Perupetro, which is based on the level of production of each field and a price formula that is based on an average price of three international crude oil prices: Fortis blend, Suez blend and Oman crudes, and a discount over this price of approximately of 72% per barrel. For Block III and Block IV, the company pay royalties to Perupetro based on an average price of three international crude oil prices, Fortis blend, Suez blend and Oman crudes, as well as the production and the incomes and expenses of each block. The company produces natural gas as a byproduct of the production of crude oil (an average of 5.5 MMcf per day during 2022). In Block IV, a certain volume of natural gas extracted is used as fuel and the excess is sent to the company's Pariñas plant to be processed and commercialized as liquid and dry gas. In June 2022, the company started its contract with Lima Gas to compress and sell compressed natural gas (CNG) (average of 0.89 MMcf per day). In Block V, the company reinject the natural gas produced back into the wells. In Block III, the company uses part of the produced gas as fuel to operate well equipment (pumping units) and the company is looking for a market to sell the excess. In this regard, the company has signed an agreement with Gasnorp to start delivering natural gas in 2023. Gas Processing Plant The company owns a gas processing plant located 7 km north of the city of Talara in Piura, Peru. The company has a delivery and gas processing and fractioning contract with Enel Generación Piura (formerly known as EEPSA), according to which Enel Generación Piura delivers wet natural gas that it purchases from onshore and offshore gas operators in the area. The company then processes and fractions the gas into two products: (i) dry natural gas, which can be used as fuel in Enel Generación Piura's gas-fired turbine; and (ii) natural gas liquids, which are sold in the Peruvian market. Under the terms of the agreement, the company is responsible for all operating costs of the gas processing plant but are also entitled to keep revenues from the sale of the natural gas liquids to third parties after payment of a variable royalty, based on the volume of gas processed, to Enel Generación Piura. The company's gas processing and fractionation contract with Enel Generación Piura expires in 2023. The company's gas processing plant has the capacity to process up to 44 MMcf per day. The company processed 31.7 MMcf per day during 2022. Approximately 85.8 % of the volume processed by the company's gas processing plant depends on the gas volumes provided by Enel Generación Piura for processing and use on its gas-fired turbines. These volumes vary per month and depend upon the power dispatch curve of Enel Generación Piura among Peruvian power generation plants. In rainy months (December to April) where hydroelectric power generation in Peru is typically higher, gas volumes demanded by Enel Generación Piura are lower than in dryer months (May to November) in which activity of thermal generators tends to be higher. During 2022 approximately 8.7% of the volume processed by the company's gas processing plant depends on the volumes of gas extracted by UNNA Energía in Block IV, approximately 5.5% depends on the volumes of gas provided by SAVIA and 2.4% on the gas provided by CNPC which the company processes and commercializes as liquid natural gas. Fuel Storage Terminals The company is a 50% partner in Consorcio Terminales with a Peruvian affiliate of Oiltanking GmbH, one of the world's largest operators of independent terminals for bulk liquid storage. In June 2014, Terminales del Peru, a new consortium that included the company's subsidiary UNNA Energía and Oiltanking Peru, was awarded a concession for the operation of the North and Central Fuel Terminals for PetroPeru. The contracts have 20-year terms and consist of the operation of four terminals in the north and one terminal in the center of the country, providing storage and dispatching bulk liquid fuel. The company's open-access terminals offer the company's customers dependable and critical handling and storage services for refined petroleum liquid products, maintaining high quality, safety and environmental standards. The company provides storage, handling and loading and uploading services for a broad range of refined petroleum liquid products, including gasoline, aircraft fuel, diesel, LPG and heavy fuel oil. The company delivers the liquids into two types of transportation systems, railroad cars and cistern trucks. Because of the strategic location of the company's assets, the company's deep-water access, inland terminals and the company's aggregate storage capacity of 2.69 MMbbl in the North and Central Terminals, the company is well-positioned to cover the needs of the company's clients, the two principal refineries in Peru. Other Terminal Operations The company is a 50% partner in Oiltanking Andina Services S.A.C. ('OTAS'). This subsidiary operates a fuel terminal named 'Terminal Marino Pisco Camisea' under a contract subscribed with Pluspetrol to operate an export terminal for gasoline, diesel, propane and butane. In 2022, this terminal dispatched 23.7 million barrels and received 5.4 million barrels of natural gas liquids (LPG, Nafta, MDBS, B-100, ULSD, B5 S50 y Diesel 2). This contract term has been extended until November 30, 2027. Additionally, through OTAS, the company is a 25% partner in LQS, which operates the 'Terminal de Químicos de Matarani', which dispatched 57,508 tonnes of sodium hydrosulfide for international mining companies in 2022. Real Estate segment The company's Real Estate segment is one of the largest apartment building developers in Peru, in terms of number of units sold and value of sales in 2022, and is focused on the development and sale of affordable housing and housing, as well as other real estate projects. Since commencing the company's operations in 1987, the company has developed approximately 1,444,650 m2 of affordable housing (approximately 23,331 units); approximately 402,198 m2 of housing (approximately 2016 units); approximately 170,416 m2 of office space (approximately 903 offices); and approximately 43,000 m2 of shopping centers (three shopping centers and strip malls). Moreover, the company is building approximately 63,344 m2 of affordable housing (approximately 1,120 units). The company's Real Estate segment also owns land parcels in Lima, comprising approximately 9 hectares as of December 31, 2022, and the company has sold undeveloped land in the past and intend to continue such sales in the future. The company undertakes a significant amount of the activities in the company's Real Estate segment with partners; through financing and commercial arrangements the company uses to purchase land and to develop real estate projects. Principal Real Estate Activities The company's real estate developments include the following products: affordable housing; housing; and commercial real estate. The company began developing affordable housing projects in 2001, following the Peruvian government's efforts to address the country's housing deficit, particularly for low-income families. The company launched the first major affordable housing project in Peru in 2007, Parque Agustino, in Lima's El Agustino neighborhood. Since 2001, the company has completed 18 affordable housing projects. As of December 31, 2022, the company was in the process of developing three affordable housing projects, including construction, presales and procuring required authorizations and permits. These projects consist of expansions of projects previously completed by the company. Affordable housing consists of apartments, usually ranging between 50 and 72 m2 in size, that are purchased using government-sponsored support programs. The Peruvian government has adopted the Nuevo Credito MiVivienda and Techo Propio programs, among others, which promote access to affordable housing in Peru by providing government subsidies to individuals for the purchase of homes. The company develops substantially all of its affordable housing projects on land purchased from the private sector. Some of the company's affordable housing projects, however, such as Los Parques de Comas, are developed through government bidding processes. Government subsidy programs like Nuevo Credito MiVivienda and Techo Propio have driven the demand for affordable housing in Peru, which has in turn increased the company's sales of affordable housing units. The company's housing developments consist of residential buildings consisted of apartments with a mid- to high-price range that do not qualify for government subsidies. As of December 31, 2022, the company was developing four affordable housing projects, which are in the construction stage. The company's housing units typically range between 67.58 m2 and 125 m2 in size. Substantially all of the company's affordable housing and housing development projects are located in Lima. The company has also purchased land to develop four affordable housing projects in Piura. The company intends to develop affordable housing projects in other cities outside of Lima. The company develops and sells office and commercial buildings, such as shopping centers. On certain occasions, the company has operated the company's commercial real estate and later sold it, such as Larcomar, a landmark shopping center which the company built in 1998 and sold in 2010. The company has also developed commercial real estate buildings in connection with the company's affordable housing and housing projects, such as the Parque Agustino shopping center. Since 1987, the company has developed 16 office buildings, three shopping centers and one medical center. Land Bank The company typically purchases land to develop real estate projects with the intention to begin construction within a 12- to 18-month period after the purchase of the land. The company may also, from time to time, purchase land for subsequent resale. As of December 31, 2022, the company owned approximately 80.6 hectares, of which 99% is located in Lima and 1% outside of Lima. The company continually evaluates opportunities to purchase new land for the company's real estate development projects. The company has a 50.45% interest in Almonte, which owns approximately 71.4 hectares of undeveloped land in Lurín, located 30 km south of Lima, as of December 31, 2022. Financing The company generally funds land purchases for its housing and commercial real estate projects through cash from the company's operations. For the company's affordable housing projects, the company generally partners with real estate investment funds and insurance companies that provide between 60% and 70% of the total capital required to purchase the land and cover certain pre-construction costs in exchange for equity in the project. Once the company acquires land for a particular real estate development project, the company obtains working capital through a credit line from a financial institution, which the company utilize to finance additional project needs as they arise. The company also obtains financing through pre-construction sales for the company's affordable housing and housing projects and, to a lesser extent, the company's commercial real estate projects. The company's affordable housing and housing projects generally require less outside financing because they are generally financed with pre-construction sales. Sales and Marketing The company typically pre-sells its affordable housing and housing units prior to and during construction and use the related proceeds to finance the construction of the units. The company's commercial and sales processes differ depending on the type of development and market segment of the development. The company primarily sells its real estate development projects through an internal sales force that is assigned to particular projects and, to a lesser extent, external brokers on a non-exclusive, commission-fee basis. The company's marketing efforts consist of newspaper advertisements, radio and television commercials, billboards and promotional offers for referrals. The company also advertises its real estate projects on the company's website and social media. For the company's affordable housing projects, the company provides post-sale customer service through the company's Ayni program, which aims to preserve the long-term value of the company's affordable housing developments by promoting a cooperative community life. Through this program, the company distributes manuals that teach best practices for living in communities, offer leadership workshops, budget workshops, promote small business development, facilitate conflict resolution and provide other services. These services are provided for a six- to eight-month period following project delivery. In 2012, the company initiated the Ayni contest for residents of the company's affordable housing projects with the aim of stimulating the sustainability of their community. Participants present an enhancement project for their community, such as a recreation center, and a jury selects the best project, which the company fund and construct.
