The CNMC has approved seven concentration operations in December, involving companies such as DFDS, Caser Seguros, Lyntia Networks, Abertis Autopistas, KKR, TADECO, and GED. These operations span various industries, including transportation, insurance, telecommunications, and healthcare. The CNMC has determined that these operations do not pose a threat to competition and do not result in significant changes to the market structure. Competition law advisors should take note of these approved operations and their implications for the involved businesses.
