MANAGEMENT COMMENTS

During this quarter, we saw a recovery in cement sales volume, which increased by 4.1%, mainly driven by sales of bagged cement and concrete for infrastructure related projects. Although there were some rains in March, affecting sales, we believe that the positive demand trend should continue for the remainder of the year. Gross profit increased by 5.5%, reflecting our continued focus on cost efficiencies to enhance profitability. Expenses increased this quarter. In an effort to optimize time and resources, collective bargaining with our labor unions is performed every three years. As an incentive to close this multi-year agreement, we offer a higher bonus for the first year, therefore increasing expenses, and 2025 is the first year of a new period. This effect is then mitigated in the following years. Despite these increased expenses, consolidated EBITDA for this first quarter was S/134.7 million, a 1.4% increase year-over-year.

This quarter, we made continued progress on our decarbonization journey, taking several important steps forward. As you may know, our plants primarily use coal for clinker production. Since 2023, a dedicated team has been actively exploring cost-efficient, locally available alternatives to coal. Northern Peru is a major producer of sugarcane, and one of its key byproducts—sugarcane bagasse (also known as "sugar brush")—is widely used as a biofuel. Building on last year’s successful lab-scale trials, we advanced to industrial-level testing this quarter, with promising results. We are also evaluating the potential use of end-of-life tires and other waste-derived fuels.

Alongside these efforts, we have strengthened our sustainability governance by reorganizing our board committees. We now have a dedicated Sustainability Committee, composed of three board members, responsible for approving our sustainability strategy, overseeing its implementation, and monitoring key ESG indicators. We believe strong governance and accountability are essential to achieving meaningful decarbonization and generating lasting social impact.

Moving on to concrete, pavement and mortar sales, this quarter revenues increased 22.3% year-over-year, mainly due to the execution of three infrastructure projects, as well as sales of pavement. During this period, we continued providing concrete for the Motupe river bank defenses, and also started shipments for the Yanacocha project and the Tarata bridge. All of these projects will continue their execution during the next quarters, guaranteeing stable demand for concrete. Moreover, pavement sales have increased steadily and we are convinced that they will continue to grow in the upcoming quarters. This is particularly relevant because it is a clear indication of the successful realization of our prospection strategy. During the past couple of years, we have worked hard on prospection works, as we understood that in order to promote the use of concrete instead of other materials, we had to go back several steps and introduce its benefits before the technical files were written. We can now reap the benefits of this long-term view, which has allowed us, on the one hand, to adjust our products and services to the requirements of each specific project, and on the other, to educate the decision makers on the benefits of concrete and precast materials for their infrastructure needs.

To sum up, this quarter we were able to deliver increased profitability, even with a temporary increase in expenses, mostly because of increasing demand, as well as a reliable cost structure. Likewise, by focusing on our strategy and providing building solutions, resilient infrastructure and continuing to search for cost-efficient ways to lower CO2 emissions, we continue to fulfill our purpose of building together the future you dream of.

ECONOMIC OVERVIEW 1Q25:

During 1Q25, the Peruvian economy showed signs of recovery and dynamism, with an estimated year-over-year growth of 4.0%, driven mainly by the construction, agribusiness, and non-traditional export sectors. The construction sector was a key driver of economic growth, largely due to a significant increase in public works. The agribusiness sector also performed well. Peruvian agro-exports—both traditional and non-traditional—posted a notable increase at the start of 2025. Non-traditional crops, which were affected by El Niño in early 2024, are expected to regain productivity in 2025, presenting an opportunity for export recovery. The fishing industry also performed well during this quarter, driven by increased anchovy catch for fishmeal and oil.

The economic outlook for the rest of the year remains optimistic. Peru’s Central Reserve Bank forecasts GDP growth of around 3% in 2025, provided a global recession does not occur. Meanwhile, the Ministry of Economy and Finance maintains a 4% growth target, emphasizing the importance of public investment and infrastructure project execution.

During the first quarter of 2025, northern Peru experienced significant rainfall, particularly in Piura, Lambayeque, and Tumbes. This period marked a stark contrast to the severe droughts of 2024, which had adversely affected the agricultural sector. The abrupt shift to heavy rains led to widespread flooding, surpassing flood thresholds in several areas, and caused damage to infrastructure and crops.

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, Holcim, 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 region.

The northern region of Peru, according to the Instituto Nacional de Estadística e Informática (INEI) and Apoyo Consultoría, represents approximately 32.9% of the country’s population and 20.0% 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 1.7 million households throughout the country as per the Ministry of Housing, Construction and Sanitation (80% qualitative and 20% quantitative deficit).

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”.

The following table shows a summary of the Consolidated Financial Results:

Consolidated Financial Results

(in millions of Soles S/)

During 1Q25, revenues increased 4.8%, mainly due to the increased sales of cement and concrete when compared to 1Q24. Gross profit increased 5.5% in 1Q25, compared to 1Q24, mainly due to lower costs as we are currently using our optimized capacity in Pacasmayo, as well as lower costs of raw materials. Profit for the period increased 6.5% in 1Q25, compared to 1Q24, primarily due to increased demand mentioned above.

SALES OF GOODS

Sales: cement, concrete and precast

(in millions of Soles S/)

Sales of cement, concrete and precast increased 6.5% in 1Q25, when compared to 1Q24, mainly due to increased sales of cement, concrete and pavement, as we continue to execute the rehabilitation and improvement of the runway, as well as the installation of the perimeter fence at piura airport. Gross margin during 1Q25 remained in line with 1Q24.

Sales: cement

(in millions of Soles S/)

Sales of cement represented 82.7% of cement, concrete and precast sales during 1Q25.

Sales of cement increased 3.9% in 1Q25, compared to 1Q24, mainly due to increased demand. Gross margin increased 2.6 percentage points in 1Q25, compared to 1Q24, mainly due to lower costs of raw materials such as coal and cement additives.
