October 12, 2021 LAMOSA: A DISCIPLINED M&A STRATEGY LAMOSA'S CERAMIC TILES M&A GBM Porcelanite - Mexico. In 2007, LAMOSA (#4 in Mexico) bought Porcelanite (#1 in Mexico), a player 5x its size, in a very aggressive but calculated move by management that resulted in a transformational milestone for the company. LAMOSA's footprint gave the company a significant edge in economies of scale, allowing it to get better supplier contracts than its peers. With such a large scale, the company reorganized its production across plants, focusing each one on a certain design or format, which resulted in longer production runs and, in turn, greater efficiencies and productivity. Ceramica San Lorenzo (CSL) South America. In 2016, - LAMOSA bought CSL to expand into Colombia, Peru, Chile, and Argentina. This move consolidated the company's position in the Americas. Five years later, management has doubled CSL's margins on account of economies of scale, rationalization of capacity, and improved logistics (exports) across the region. At the time of the acquisition, LAMOSA already exported to South America and by getting those assets, it redirected its capacity in Mexico to domestic demand and other markets while increasing CSL's utilization capacity at the same time. - Eurocerámica Colombia. In 2020, LAMOSA acquired Eurocerámica to strengthen its position in Colombia. This acquisition was seamlessly integrated with CSL's assets and turned LAMOSA into Colombia's second-largest ceramic tiles producer, only behind Corona. Grupo Roca - America/Europe. In 2021, LAMOSA announced the acquisition of Grupo Roca's ceramic tiles business, with plants in Brazil and Spain, and a strong business in the United States. Synergies should arise from economies of scale and improved logistics, as well as the integration of best practices and technologies. Hard currency revenues. With the addition of these assets, LAMOSA will now sell -13% of its total revenues in USD and EUR. 20 plants 130M m² 130M m² 20 plants 130M m² 187M m² 2 plants 23M m² 3 plants 23M m² 20 plants 130M m² 2 plants 23M m² 3 plants 23M m² 2 plants 2 plants 11M m² 11M m² 225M m² 1 plant 35M m² 3 plant LAMOSA/CERAMIC: THE ROAD TO GROWTH IS PAVED WITH TILES. | 25
