Oscar Stephens is a trusted advisor to sponsors, developers, and financial institutions in renewable energy and infrastructure financings, bringing more than twenty years of experience across the U.S. and emerging markets to every engagement. His practice encompasses a broad range of lending and capital markets transactions, with particular depth in cross-border work throughout Latin America - one of the world's most complex and compelling regions for energy and infrastructure investment.
Oscar's transactional experience spans the full spectrum of sophisticated financings: unsecured and secured syndicated facilities, Rule 144A and Regulation S note offerings, private placements under Section 4(a)(2) of the Securities Act, and intricate structured financings of all kinds. He represents banks, borrowers, and issuers in term and construction loans, project bonds, acquisition and leveraged financings, high-yield bond offerings, future flow securitizations, and receivables- and asset-backed financings - consistently delivering clarity, sound judgment and a business-oriented approach to transactions of significant complexity.
In renewable energy and infrastructure, Oscar has developed particular expertise representing sponsors and operators of solar projects, wind farms, international airports, highways, and port terminals. His industry knowledge extends further into oil & gas, banking, financial services, fintech, technology, telecom, manufacturing, and agriculture and food & beverage - giving him a comprehensive understanding of the sectors his clients navigate.
Oscar also counsels growth-stage corporations entering the U.S. market, advising on holding company structures, multi-jurisdictional operations, and venture capital funding. He regularly represents foreign financial institutions on New York law matters and multi-currency facilities, and advises sovereign and quasi-sovereign entities on U.S. securities law compliance.
Conducting business fluently in both English and Spanish, Oscar brings a genuinely bi-cultural and pragmatic perspective that proves invaluable in cross-border transactions. His command of civil law traditions throughout the Americas - combined with deep expertise in non-recourse financing, public-private partnerships, concession and offtake agreements, and BOOT/BOT structures - positions him to navigate the legal and commercial complexities that define the most challenging international deals. This combination of legal fluency, cultural insight, and practical problem-solving has been a defining strength throughout his career.
