Second Quarter 2021 Earnings Release Management Comments During 2 Q 21 our volumes continued strong, despite the high levels of uncertainty, since, more than a month after the runoff for the Presidential elections this past June 6 , the winner has not yet been officially proclaimed . This shows our resilience, especially in terms of sales of bagged cement, which have sustained its strong performance . As expected though, volumes from private projects have been affected by the political situation, and will most likely remain low for the rest of the year . However, we are confident that we will continue experiencing high sales volumes, since demand from the public sector, mainly from the infrastructure spending related to the government to government agreement with the UK government for the reconstruction of the damage cause by El Niño has already started materializing and will increase during the second half of the year . We would like to briefly go into further detail in terms of cement, concrete and precast sales, since the comparison to 2 Q 20 shines little light on their true performance this quarter . If we look at quarter - on - quarter sales, these have decreased slightly, however, this does not affect our expectations for year - end sales since we expected this trend . If we compare sales of cement, concrete and precast from this quarter to those from 2 Q 19 , as the most recent pre - pandemic comparison for a similar period, they increased 41 . 8 % . Although the largest portion of this growth can be attributed to bagged cement sales, concrete and precast also increased . Precast continued to perform outstandingly, as we mentioned last quarter, mainly due to our efforts to expand the customer base . Concrete had a small set back as most of the investment from private projects has come to a halt until the political situation becomes more clear . However, volumes from the public sector should offset this loss in volumes and we expect to see record levels again as soon as the third quarter . During this quarter, our solid and innovative commercial efforts were rewarded, as we are very pleased to have received a Silver Effie award . The Effie Awards honor the world's most effective companies and brands . Pacasmayo was a winner in the brand experience category, for “construyexperto . pe”, an online platform created to redesign the foreman Dz s experience, with training and tools that help them be more efficient . We are very proud of the award, which acknowledges the effectiveness of our client - focused strategy . Finally, as we have always mentioned, our people are definitely our most important asset . This year, our ranking place in Merco Talento Perú, which aims to identify the 100 most attractive companies to work, has improved 37 positions from last year . This ranking is based on eight different evaluations, which are integrated to obtain the monitor that is made public every year . We believe this is a significant improvement, which shows our commitment to improve our human capital management . We will strive to continue improving in this ranking every year . To sum up, this quarter has yet again proven the resilience of our business, as well as the effectiveness of our commercial strategy . We expect sales to continue the positive trend for the rest of the year, as the self - construction segment remains solid and the added demand from the public sector should offset a weaker private sector . As always, we remain committed to continue generating value and to improve our business in the most sustainable manner . 4

Second Quarter 2021 Earnings Release Economic Overview 2 Q 21 : During 2 Q 21 , the runoff election between Pedro Castillo and Keiko Fujimori took place on June 6 . The result was extremely tight, and, as of the day of this report Castillo leads with less than 0 . 5 % margin, while Fujimori claims that there have been irregularities during the voting process and has taken a variety of political and legal measures that are still being resolved . This has resulted in high levels of uncertainty, that are likely to prevail for some months . This uncertainty arises not only from the fact that there is still no official pronouncement from the highest electoral authority regarding who will be proclaimed President, but also because who has the best chance of being declared the winner, Pedro Castilllo, has not given clear signals of what his government will be like, or who will participate . Castillo represents a radical left wing party, which despite having shown some signs of moderation in recent weeks in some aspects such as the inclination towards free market policies on the macroeconomic side, continues to speak of drafting a new Constitution for Peru . Nonetheless, the Peruvian Central Bank (BCR for its Spanish acronym) has not modified its GDP growth projections for the year, since it believes that the negative effect of the political uncertainty will be offset by higher public spending and a strong self - construction segment . During 2 Q 21 , we have seen the self - construction segment remain strong and the expectation is for it to continue the same path for the rest of the year . In terms of public spending, its growth comes basically from infrastructure spending, most of it from Reconstruction related works, mainly the government to government agreement with the UK government, and the plans implemented to fight against COVID - 19 such as Arranca Perú and those included in the National Competitiveness Plan . Finally, it is very important to mention that, after being the country with the most deaths per million and one of the last ones to begin to vaccinate its population, Peru is finally performing better in its fight against COVID - 19 . Peru is the country that has most decreased its number of deaths in Latin America and should have around 20 % of the population vaccinated by the end of July, and 80 % by the end of the year, as long as the new government maintains the current efforts and strategies . This increase in the speed of vaccination will not only protect people’s health, but will also help reactivate the economy 5

Second Quarter 2021 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 28 . 9 % of the country’s population and 14 . 9 % of national Gross Domestic Product (“GDP”) . Despite the country’s 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 ofHousing, 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” . 6 Peruvian Cement Market Cement Dispatches and Market Share *Import figures are sourced from Aduanet.

Second Quarter 2021 Earnings Release Infrastructure Investment in the Area of Influence: R e co nst r uct i o n o f t h e N o rth A boost in infrastructure is expected from the government’s reconstruction plan, now that the agreement between the Peruvian and UK government is under execution . This agreement 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 . 50 % of this investment is expected to be executed by the end of 2021 . 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 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 2 Q 21 , we continued shipping to the Talara Refinery, and the Salaverry Port . These projects should be executed and finished in the next 12 to 18 months .
