Financial and corporate

Since its 2018 inception, Martínez de Hoz & Rueda (MHR) has swiftly become a leading firm in Argentina, particularly in project development. The full-service firm recently opened a fully operational office in Montevideo, Uruguay. MHR provides top-tier legal advice, focusing on understanding clients’ businesses, goals, and needs. With senior offices in Buenos Aires and Neuquén, MHR excels in the oil, gas, and energy sectors.

The firm also boasts strong banking and capital markets practices. 

 

Highlights

The firm continues to play a leading role in Argentina’s sustainable finance and energy transition. It advised CAF on one of the country’s largest syndicated loans of 2023, supporting climate-focused projects aimed at reducing emissions. In project development, the firm provides comprehensive legal counsel to Fortescue on Argentina’s largest green hydrogen initiative, covering regulatory, permitting, and contractual matters, and has contributed to shaping the Federal Hydrogen Promotional Regime. Additionally, the firm acted for the International Finance Corporation (IFC) in the financing of the world’s largest electric ferry—marking the first-ever blue financing in the maritime and electric transport sector globally. This groundbreaking transaction required aligning emerging blue finance principles with international environmental standards and Argentina’s regulatory framework.
