MANAGEMENT COMMENTS

During the third quarter of 2026, our operational performance remained exceptionally solid, driven by a 14.2% increase in the sales volume of cement, concrete, and precast. This robust demand directly contributed to a 16.3% rise in revenues, which reached S/ 667.4 million. We successfully leveraged this growth alongside higher selling prices to achieve a consolidated EBITDA of S/ 233.1 million, an outstanding 45.1% increase. Consequently, our consolidated EBITDA margin expanded by 7.0 percentage points to reach an impressive 34.9%. Complementing this strong performance, our net income rose by 69.8% to S/ 121.4 million, primarily driven by higher gross profit and lower administrative expenses. In the concrete, pavement, and mortar segment, although revenue was impacted by the completion of shipments for the Yanacocha and Motupe projects, gross profit demonstrated a strong recovery due to a commercial strategy focused on value creation and profitability. Meanwhile, growth in precast products was mainly supported by increased demand for pavers in public and private projects, particularly across Piura, Trujillo, and Chiclayo.

Furthermore, we continue to drive the industrialization of the construction sector by expanding our portfolio of advanced construction solutions, designed to address complex infrastructure challenges efficiently and sustainably. A key highlight is our Pipe Jacking system using concrete pipes, which allows for the execution of underground works while significantly minimizing surface excavations and logistical interferences. This method offers high precision, speed, and structural capacity, reducing the impact on urban traffic and the surrounding environment. In parallel, our hydraulic and soil containment solutions have proven highly effective for projects in contact with water and critical soils. Our concrete sheet piles—prefabricated structural elements produced under strict ISO 9001 quality controls—provide essential functions such as erosion control, scour protection, soil containment, and slope stabilization. These elements guarantee faster on-site execution, high precision, full control of the construction process, and superior durability in aggressive environments. The success of this solution is validated by the Piura River defense project, where we have secured the specification of an additional 4.4 kilometers of concrete sheet piles. By accompanying our clients from engineering specification through to manufacturing and assembly, we reaffirm our commitment to delivering durable, efficient, and reliable infrastructure solutions.

Beyond our financial results, we continue to build trust, drive sustainability, and generate a positive impact in the country. We are immensely proud to announce that we reached the 9th position nationwide in the Merco ranking. This achievement consolidates our presence in the Top 10 in Peru for the fourth consecutive year and reaffirms our position as leaders in our sector for 11 uninterrupted years. Maintaining this leadership over time is the direct result of the hard work, effort, and resilience of the entire Cementos Pacasmayo team, reflecting a culture that bets on good people and outstanding professionals.

We also recognize that the great infrastructure projects in northern Peru are built not only with cement, but with the talent and dedication of our foremen (maestros de obra). To support them, we created “Construye Experto,” a digital ecosystem designed to boost their development and strengthen our loyalty and growth strategy. The impact of this evolving value proposition speaks for itself: we now have more than 5,000 foremen with access to benefits and learning opportunities, alongside a 157% monthly growth in the accumulation of “Construye Puntos” (builder points). When our foremen grow, what we build together grows as well.

Our commitment to the development and well-being of the communities where we operate was celebrated this quarter through significant recognitions for our “Juntos contra la Anemia” (Together against Anemia) and “Sueños en Concreto” (Dreams in Concrete) initiatives. These recognitions represent concrete stories and results: 310 children and 58 pregnant women recovered from anemia, and over 1,000 homes were improved, benefiting more than 4,000 Peruvians. Furthermore, “Juntos contra la Anemia” won the first edition of the Socios En Salud 2026 Awards. Developed in the district of Elías Soplín Vargas, this collaborative effort between the company, authorities, health professionals, and families successfully reduced the prevalence of childhood anemia in the district from 17% to 9%, bringing equitable and timely health services to early childhood.

We conclude this quarter with confidence in our strategic momentum and operational strength. Beyond the financial results, our progress reflects a meaningful contribution to Peru’s economic and social development—creating tangible opportunities, improving living standards in our communities, and generating sustainable value for all our stakeholders.

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 Perú, 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.(1)

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”.
