First Quarter 2020 Earnings Release Management Comments During 1 Q 20 , the unprecedented event of a global pandemic hit Peru . On March 15 , 2020 , President Vizcarra declared a state of emergency to prevent the massive spread of COVID - 19 , which would collapse our precarious healthcare system . The country has since been on hold, with no production or sales of any good or service except those considered essential . Following this government mandate, our operations have been stopped since March 16 and, as of the date of this report, we are unsure when they will be allowed to restart . First, we believe it is important to mention the trend we were experiencing before the state of emergency was declared . If we look at revenues for the first two months of the year, compared to the same period of 2019 , we see an outstanding increase of 14 . 4 % . As in previous quarters, the concrete sector was performing exceptionally well, increasing almost 53 % year - on - year as of February 2020 . We believe this trend, as well as the possibility of the government focusing some of its recovery plan resources in infrastructure spending, may help in the recovery in sales volume . We are strictly following the measures mandated by the government and so cannot produce or sell any cement except a very small amount for the mining industry . However, we have been working probably more than ever, to not only have all the safety measures and protocols in place to begin production as soon as legally possible, but also, working towards the future . We have been working with the Ministry of Production to present our plan to restart production, with the safety of our employees, as always, as our top priority . We have used this opportunity to start some initiatives we had already been considering, such as more extensive work from home arrangements . We have been pleasantly surprised with the results during the first weeks of home office for all . We were expecting some level of communications issues and meetings being less effective, since we are used to face - to - face interaction . However, the opposite has been proven so far ; communication, especially with leaders and managers, has been enhanced, turnaround and response time has improved and meetings are shorter and more effective . These results encourage us to continue this working method beyond legal requirements, as we believe it will bring about higher productivity levels, increased well - being, and work - home balance for our employees . Lastly, we would like to make it very clear that we remain focused on our long - term goals and firmly believe in the potential of our industry, and our company’s ability to capitalize on this potential . We are aware that the world has changed and we need to adapt . We are ready for the challenge and will continue to work hard to generate long - term value . 4

First Quarter 2020 Earnings Release The plan that the Government has already implemented adds up to 12 % of GDP . To give liquidity to this plan, the Government issued two bonds for the sum of US $ 3 billion, which obtained high demand, therefore attaining excellent rates : The Global Bond 2026 at a rate of 2 . 39 % , and the Global Bond 2031 at a rate of 2 . 78 % , The construction sector will definitely be affected in this recession, especially the self - construction sector, which still represents an important part of our sales . However, in recent quarters, we have seen how concrete has begun to take a more predominant role, and in this sense, growth in infrastructure, if it is a sector prioritized by the Government, could help mitigate the fall in self - construction . 5 Quarantine 4 continuous weeks 6 continuous weeks and 2 more throughout the year 6 continuous weeks and 4 more throughout the year Restrictions on economic activity In particular sectors until the end of winter In particular sectors throughout the year Generalized and throughout the year Adjustments to costs in business and families Moderate.

In Peru, as in the rest of the world, social isolation measures have been implemented that have affected, and will continue to affect, the economy significantly . It is still too early to know the full impact, since, as Apoyo Consultoría indicates, the business environment of the following months will depend on uncertain events that are currently under development . On March 15 , 2020 , the Peruvian government declared a state of emergency and mandatory social isolation, as well as the closure of borders . All activities except essential activities (production and supply of food, pharmaceuticals and fuel, financial entities, insurance and pensions, health sector and the media) have been suspended . The mandatory social isolation occurred initially for 15 days but has been extended, for now, until May 10 , 2020 . It is still uncertain how the return to activities will occur ; it is likely that after the quarantine period, additional measures of partial social isolation will be maintained . The timely publication of operating protocols will be key for companies to properly plan the reactivation of their businesses . It is likely that it will take until the end of the year for most economic activities to operate normally . GDP growth for 2020 will depend on several factors, such as the final quarantine period, the size of the government's economic recovery plan, and its level and speed of execution . Below are the scenarios according to Apoyo Consultoría Economic Growth Scenarios

First Quarter 2020 Earnings Release Peruvian Cement Industry Overview : Peruvian cement demand is mainly supplied by Pacasmayo, UNACEM and Cementos Yura, and by Caliza Inca, imports and other small players to a lesser extent . 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 29 % of the country’s population and 18 % 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” .

First Quarter 2020 Earnings Release Infrastructure Investment in the Area of Influence : 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 . We do not know yet how these investments will be affected by the economic effects of COVID - 19 . 7

First Quarter 2020 Earnings Release The projects below were those in execution or close to execution during 2020 . Most of these projects will demand concrete, pavement and other precast products which are very important in terms of our new strategy as a building solutions company . Given the economic impact of COVID - 19 , and the fact that we do not yet know the full extent of it, we cannot guarantee that these projects will continue during 2020 . * In execution Also, significant spending was directed towards reconstruction works to address the damage caused by Coastal El Niño in 2017 , based on Government’s Reconstruction Plan . We had started seeing some acceleration in shipments for reconstruction related projects during 2019 and the first months of 2020 . However, we are uncertain about the execution of these projects now that the government will have to focus their efforts on COVID - 19 and its effects .
