Bolsa de Madrid
On 18 July 2007, the board of Altadis backed a €16.2 billion offer for the company by Imperial Tobacco (now Imperial Brands). The acquisition was cleared by the Spanish stock market regulator on 7 November 2007, paving the way for the creation of the world's fourth largest tobacco company. The acquisition was completed on 25 February 2008 with the delisting of Altadis from the Bolsa de Madrid.
