Chile > Corporate and M&A

Housing ‘a world-class corporate and M&A practice that is fully comparable to what might be found in US or global firms‘, CMS Carey & Allende‘s 23-strong department specialises in complex transactions, such as unsolicited tender offers and international expansion plans via acquisitions. The client base derives from a range of industries, including finance, energy, infrastructure, real estate, construction, telecoms, and hotels and leisure. Managing partner Ramón Valdivieso (M&A operations both in Chile and other parts of Latin America) co-heads the corporate and M&A group alongside Jorge Allende Destuet, who regularly participates in cross-border business combinations. Also highly regarded are M&A specialist Luis Felipe Arze and Fernando De Cárcer (M&A, capital markets and corporate law).
