Second Quarter 2020 Earnings Release Management Comments The second quarter of 2020 has probably been the most challenging period in Pacasmayo’s history . We were unable to produce or sell cement for more than half of the period resulting in an unprecedented decrease in sales volume, high costs from stop in production, and consequently a decrease in EBITDA . This is certainly not particular to our business, as the country’s GDP is estimated to have fallen around 40 % in April compared to April 2019 . However, we do believe there are reasons to be cautiously optimistic about the medium term . The construction sector, which in this case includes cement production and commercialization, was included in phase one of the plan to reactivate the economy . As we mentioned in our first quarter results, anticipating the return to operations, we presented and got approval to restart production from the Ministry of Production, with the safety of our employees, as always, as our top priority . Therefore, we were able to restart producing and shipping cement on May 20 , from our three plants . We would like to mention that, as shown above, shipments have steadily recovered since we restarted operations . If we look at cement sales, in June 2020 , the decline has only been close to 20 % as compared to June 2019 . The health and safety of our employees is our undisputed top priority . Since before the declared state of emergency we started analyzing the best way to safeguard our employees, both at home, given them the resources needed to stay healthy, and more so once we were allowed to restart operations . We continue to operate with as little workers as possible in our plants, and those that have to go, follow strict guidelines for social distancing, hygiene, and regular checkups by our health and safety team . All of our administrative staff continues to work from home and we plan to continue working this way until we are certain that the benefits of returning to the office outweigh the risks . As we mentioned during the previous quarter, we have been pleasantly surprise by work from home arrangements so we will continue to support it, as it is encouraging productivity and better work - home balance . We believe empathy and solidarity are key, especially in times of crisis . This is why we would like to share with you some of the actions that we have taken to help our stakeholders during these difficult times . First, for our workers, we have implemented a nutritional program to help those with BMI indicators above healthy levels, online doctor’s appointments, safety kits, and psychological and emotional support for all of them . For our communities, through our volunteering program, we have helped with the disinfection of streets in some of our areas of influence, virtual training programs for some of the communities we regularly support, as well as support for local authorities offering them safety kits and food supplies . We firmly believe on building a better future together and now is the time to show our support to our workers, their families, the communities in our area of influence and those less fortunate during these difficult times . Moving on to cement demand behavior since we restarted operations and our expectations for the year, there are two main issues that need to be discussed . First, the self - construction segment has once again proven its resilience . We were expecting very low sales volumes to this segment since it is generally tied to employment and disposable income and we expected both of those to be severely affected by the pandemic . However, since employment in the North is tied to the agricultural segment, which has had a good year, it was less affected than in other areas of the country . If we add the size of the informal sector in the North, which did not quite stop during the lockdown, we can see that some of the negative effect from other segments was partially offset, resulting in better than expected results . It is still too early to conclude, but we have been pleasantly surprised by its performance during these first 6 weeks since the restart of operations . Secondly, on the public sector front, the execution of the Reconstruction plan from El Niño in 2017 will finally pickup, since the Peruvian government signed an agreement with the Government of the United Kingdom in June for the execution of S/ 7 billion soles during the first 2 years . The UK government will provide technical assistance for the construction of hospitals, schools and river defenses, all of which should be finished by June 2022 . This is excellent news for Pacasmayo, but more importantly, for the Northern region, since the much needed infrastructure will finally be built, hopefully in the most efficient manner . Finally, we believe it is important to mention that, the digital transformation strategy we have had in place since 2018 has proven very useful in this new reality . One of the most relevant initiatives has been one to digitalize our relationship with construction companies of all sizes, through Pacasmayo Profesional, allowing them to program 4

Second Quarter 2020 Earnings Release their requirements and track their shipments online . It integrates all of our back office platforms for an optimal customer service experience . This tool allows for the planning and programming of the fleet with efficiency algorithms to optimize the resources (mixers, pumps, drivers) according to the clients’ requirements . To summarize, these are challenging times for all, as we face an unprecedented economic and health crisis . However, we feel we are in a good position to face it . We believe that our emphasis on financial responsibility, sustainability, our client - centric view and strive for innovation will help us navigate these difficult time and will proof its value in the medium and long term . 5

Second Quarter 2020 Earnings Release Economic Overview 2 Q 20 : Throughout 2 Q 20 , Peru continued in mandatory social isolation, although with some releases of economic activities from May, to avoid the complete stop of economic standstill . The GDP for 2020 is estimated to have a drop of between 14 % and 20 % , according to Apoyo Consultoría with a significant recovery during 2021 and 2022 . The Government has announced various initiatives to reactivate the economy, after the paralysis of most sectors for more than 100 days . These initiatives represent 14 % of GDP, although less than half has been executed . The economic recovery has already started, but it will be slow . The reopening of the economy is taking place in phases, with construction being part of phase 1 . Cement production and shipments began in mid - May, and although definitely hit on the demand side, we expect a gradual recovery of volumes in the following months . Especially relevant for cement dispatches in the north is the execution of the reconstruction plans . In June, the Peruvian government signed an agreement with the government of the United Kingdom, for the execution of a package of S/ 7 billion to be executed during 2020 and 2021 . Through the agreement, the United Kingdom will provide the structure, strategy and governance processes necessary for the timely delivery of all works, promoting efficiency and avoiding corruption . This model has already been used successfully for the construction of the necessary infrastructure for the Lima 2019 Pan American Games, therefore favorable results are expected this time as well . 6

Second Quarter 2020 Earnings Release Peruvian Cement Industry Overview : Pacasmayo, UNACEM and Cementos Yura mainly supply cement demand in Peru . Pacasmayo primarily supplies the northern region of Peru, while UNACEM supplies the central region and Cementos Yura the southern region . The northern region of Peru, according to the Instituto Nacional de Estadística e Informática (INEI) and Apoyo Consultoría, represents approximately 23 % of the country’s population and 14 % of national Gross Domestic Product (“GDP”) . Despite the country’s sustained growth over the last 10 years, Peru continues to have a significant housing deficit, estimated at 1 . 9 million households throughout the country as per the Ministry of Housing, Construction and Sanitation . In Peru, the majority of cement is sold to a highly fragmented consumer base of individuals that tend to gradually buy bags of cement to build or to improve their homes, a segment the industry refers to as “self - construction” . *Import figures are sourced from Aduanet. They represent quantities of imported cement, not shipped cement.

Second Quarter 2020 Earnings Release Infrastructure Investment in the Area of Influence : Reconstruction of the North As we mentioned above, a boost in infrastructure is expected from the government’s reconstruction plan, now that the agreement between the Peruvian and UK government has been signed . This agreements includes an investment of S/ 7 billion in 2 years and includes 74 schools, 15 hospitals and integral solutions for 17 rivers, 5 brooks, and drainage of 7 Northern cities . This will have a significant impact on our cement shipments, as most of this budget is concentrated in our area of influence . Other projects Although the anticipated increase in Peru’s large infrastructure projects has been delayed, this remains an important growth driver for the country and also a necessity due to Peru’s significant infrastructure deficit . Although the progress of these projects has been slow, we have continued shipping cement to the ongoing projects, which are shown below, along with the potential demand for the next 5 years . During this quarter we resumed shipments to the Chiclayo airport, the Talara Refinery, and started shipping to the Salaverry Port . These projects should be executed and finished in the next 12 to 18 months . Source: Company filings, Proinversion, MINEM 8
