October 12, 2021 GBM HISTORICAL MARKET SHARES (VOLUMES SOLD) After the acquisition of Porcelanite in 2007, LAMOSA positioned itself as the leader in the Mexican ceramic tiles market, more than doubling in size when compared to the second-largest player. Despite the industry still has room for further consolidation, with several family-owned Mexican ceramic tile producers holding less than 3% of the market, it appears that the largest competitors are preferring the organic growth route, with all companies (except for Vitromex) having added capacity since 2010, while no acquisitions have happened in Mexico over that same period. In contrast, many acquisitions have taken place abroad, with LAMOSA and Mohawk (Daltile's holding), the largest ceramic tile producers in the world, being particularly active.
