The Pyrenees Mountains may divide France and Spain, but Altadis unites the countries for a smoke. Born of the 1999 merger of Spain's Tabacalera and France's Societe Nationale d'Exploitation Industrielle des Tabacs et Allumettes (Seita), Altadis is one of the world's largest tobacco firms. Altadis brands include Ducados, Fortuna, Gauloises, and Gitanes. Its cigar operation (the top worldwide) produces Antonio y Cléopatra, Farias, Hav-A-Tampa, and Montecristo and controls a quarter of the world's cigar market (mostly from its Altadis USA unit). Altadis was acquired by Imperial Brands in February 2008 and sold its about 50% stake in Aldeasa, a top operator of Spain's duty-free shops, to Autogrill in April 2008.
