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). Organic growth at the firm saw the promotion of Ignacio Errazquin to partner in January 2021, while at senior associate level, Sebastian Barros is active in energy, infrastructure and natural resources transactions.

The practice also fields experts in telecoms and IT service operators’ strategic alliances, as well as telecoms-related regulatory compliance. The principal figures are corporate/M&A group co-head Ramón Valdivieso, who has substantial technology, media and communications sector knowledge; and IT specialist Diego Rodríguez, who assists with outsourcing agreements and software as a service (SaaS) contracts.
