MANAGEMENT COMMENTS

During this quarter, our country, and particularly the North of Peru was affected by heavy rains and landslides. During March, a cyclone, known as Yaku, reached northern Peru and mainly affected the regions of Tumbes, Piura, Lambayeque and La Libertad. This is an extremely rare meteorological event outside tropical area. Our sales were understandably affected by this event, mainly during March, when sales volume decreased by 23.4% as compared to the same period of 2022. Nonetheless, due to proper cost management and the decrease in the use of imported clinker, we were able to increase our EBITDA margin by almost 1 percentage point, reaching 25.1%. The outlook is still uncertain, especially considering that after the cyclone subsided, heavy rains started again during April due to the increase in the temperature of the ocean. We will continue to focus on efficiencies to deliver the best possible results in the current context.

We would like to turn the focus to two main issues that are extremely relevant in today’s complex climate context. First, we want to emphasize, as we have always done, that for Pacasmayo, people will always come first. During these difficult times, that have left many without a home, we have strived to help as much as possible in order to alleviate their losses. In the city of Pacasmayo, an area that is not usually severely affected by rain, floods or landslides, we acted promptly mitigating the devastating effects of cyclone Yaku. We deployed a detailed step-by-step plan that included: 1. Clearing the excess water, that in some areas was over 1-meter-high, 2. Cleaning the solid waste left after the water had been cleared, and 3. Sanitizing the streets. Unfortunately, in most of the country, sewage systems are still precarious, and when rain floods the streets, there’s the possibility of collapsed sewage systems, posing a very alarming safety threat. This is why the immediate clearing and sanitizing is an urgent matter in order to prevent more severe problems. Finally, we would like to mention that, despite the rainfall and flooding, our operations presented no relevant damages and the current construction for the optimization of our Pacasmayo plant has not suffered any delays.

The second issue that we would like to focus on, relates to the very evident need for preventive works and resilient construction. Weather patterns such as El Niño, that occurs periodically have devastating effects in our country’s infrastructure. Since these events are recurrent, and climate change is going to potentially make them stronger, more frequent and possibly less predictable, the way in which we build our infrastructure is key to prevent adverse effects. In our own experience, the concrete pavement used in over ten roads and avenues in Piura, has endured the heavy rainfall and flooding, much better than any other alternatives. In a similar manner, the preventive work we did in our quarry in Tembladera, by which we channeled the river, significantly reduced the impact of recent heavy rains in this area. We need to insist on the importance for these preventive works and demand that new construction works have a focus both on sustainability and resilience. Extreme climate patterns will continue, and we need to make sure that, as a country, we are prepared to face them.

To sum up, the start of 2023 has brought us some difficulties, which we are facing in the best possible manner, focusing on the support that our people and our country require. However, let us not forget that challenges bring opportunities; we are at a crucial moment to make a difference in the way we face the next natural disaster or climate phenomenon. As a company, we are prepared to tackle the challenge, not only with our products and services, but with our sustained drive for collaborative action, to make sure that sooner, rather than later, we live in a country that has infrastructure that is as resilient as its people.

ECONOMIC OVERVIEW 1Q23:

During this quarter, economic activity, especially in the north of the country, was affected by the heavy rains, and landslides that occurred in March. A cyclone, known as Yaku, reached northern Peru and mainly affected the regions of Tumbes, Piura, Lambayeque and La Libertad. This phenomenon, and the rainy season in general, have so far left economic losses estimated in 4,000 million dollars according to Alonso Segura, former Finance Minister.

Unfortunately, after the cyclone ended, the rains have continued due to the increase in the temperature of the water, which is above its normal values in the northern and central areas of the Peruvian ocean. During the month of April there has been rainfall above normal, and it is expected to continue for at least a few more weeks.

It is important to mention that private investment contracted by 0.5% in 2022 and this trend is expected to continue during 2023. This contraction occurs in a scenario of slow recovery of business confidence, which would have a negative impact on the decisions of new investment projects.

At the political level, during 1Q23, there was some stabilization, marked by an improvement in the relationship between the Executive Branch and Congress. Additionally, the announced creation of the National Infrastructure Authority (ANI for its Spanish abbreviation), whose objective is to carry out infrastructure works, as well as disaster prevention tasks and control of hydrographic basins, has the potential to boost new projects in the medium term, especially considering the need to deal with the potential El Niño Phenomenon.

PERUVIAN CEMENT INDUSTRY OVERVIEW:

The demand for cement in Peru is covered mainly by Pacasmayo, UNACEM and Cementos Yura, and to a lesser extent by Caliza Inca, imports and other small producers. Pacasmayo mainly covers the demand in the northern region of the country, while UNACEM covers 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 32.5% of the country’s population and 16.0% 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”.
