McGuireWoods Adds Alex Weniger-Araujo and Andrei Sirabionian to Capital Markets Practice
"McGuireWoods hires partners Alex Weniger-Araujo and Andrei Sirabionian into its Capital Markets Practice to advise on SPAC transactions, IPOs and broader securities law matters."
Alex Weniger-Araujo joins McGuireWoods from Loeb & Loeb and will serve as a partner in the Capital Markets Practice. He and Sirabionian have guided more than 100 companies through SPAC transactions and business combinations and collectively bring more than three decades of experience representing international and domestic issuers, underwriters and investors in public and private securities transactions. Weniger-Araujo counsels clients on reporting requirements, corporate governance, stock exchange rules and ongoing securities law compliance. Before entering private practice, he led product development for a legal technology company, founded a real estate analytics SaaS platform and served as general counsel at a New York–based venture development firm focused on Seed to Series A stage companies.
Andrei Sirabionian also joins McGuireWoods from Loeb & Loeb as a partner in the Capital Markets Practice. He counsels clients on reporting requirements, corporate governance and securities law compliance and, in addition, has represented entities in acquisitions and divestitures, spinoffs, joint ventures and going-private transactions.
The two partners rejoin McGuireWoods colleague Shahrooz Shahnavaz, a Los Angeles tax partner who arrived from Loeb & Loeb in 2025. The trio has collaborated extensively, with Shahnavaz advising on tax structuring for SPAC transactions and de-SPAC business combinations, and together they deepen McGuireWoods’ capabilities on SPAC IPOs, business combinations and related capital markets matters.
