Allende & Brea‘s corporate and M&A practice is a popular choice for international companies seeking advice on complex, high-value transactions in Argentina. The team has a strong presence in a variety of sectors, including technology, banking, transport, mining, real estate, agribusiness, and pharmaceuticals, and works closely with the firm’s insurance team to provide tailored corporate and M&A advice to both multinational and domestic insurance companies. Valeriano Guevara Lynch, a corporate and M&A specialist with over twenty years of experience, and Santiago Sturla, whose expertise spans M&A, shareholders’ conflicts, finance and restructuring, project finance, and foreign investments, lead the practice. Raúl Fratantoni is regularly engaged by Argentine closely-held companies and family-owned businesses; Tomás Di Ció is adept in M&A, commercial agreements and general corporate law; and Marcos Patrón Costas is noted for his experience in transactions involving the energy and infrastructure sectors. The practice is supported by a growing cohort of high-performing associates, including Nicole Dillon. As we go to press the firm has announced the further strengthening of the corporate practice with the hire of seasoned transactional specialist Pedro Menéndez San Martin from Estudio Bunge – effective as of October 2025.
