October 12, 2021 GBM LAMOSA: SCALE VERSUS ITS MEXICAN PEERS Sometimes size does matter. One of LAMOSA's main competitive advantages in Mexico is its scale, which provides flexibility across its production plants and, as has been the case in 2021, the opportunity to capture rapid increases in demand from changes in consumer behavior. Moreover, by having plants closer to distributors, it has pricing power from lower transportation costs. The illustration below clearly shows how LAMOSA's four plants in Tlaxcala allow the company to better serve the center and southeast regions of Mexico when compared to all its competitors. Being a heavy product to mobilize, ceramic tiles and adhesives could be seen as freight-intensive products, while transporting them over long distances can prove inefficient. The product that travels more is the premium one, and the company's pricing power allows to compensate for the logistics costs. Thus, it is fair to say that the manufacturer that is closer to its distributors has a certain advantage in terms of pricing.
