Sofia Carreiro

I am head of our Corporate & M&A practice in Portugal. I advise domestic and international clients on cross-border M&A, complex restructurings and joint ventures, with a focus on technology, energy, healthcare, aerospace and other regulated industries. I also have extensive experience in commercial contracts, including distribution and franchising.

With over 25 years of experience in corporate law, I have advised private and publicly listed companies, state-owned entities and international investors. My practice combines a solid command of complex regulatory frameworks with a pragmatic, business-oriented approach, providing clients with clear and actionable guidance.

Over the years, I have developed specialised expertise in advising on transactions and projects across highly regulated and strategic industries. My sector focus includes technology, energy, healthcare and life sciences, and aerospace, involving complex regulatory frameworks and cross-border transactions. This breadth of experience allows me to provide clients with sector-specific insights and to anticipate challenges that may arise in sophisticated corporate transactions.

My advice to clients covers the full spectrum of corporate transactions. I have extensive experience counselling on joint ventures and shareholder agreements, having led the negotiation of numerous structures in both public and private sectors. My practise also encompasses asset deals and corporate reorganisations, including winding up and liquidation, changes of legal form, establishment of holding structures, and internal reorganisation of companies. These assignments frequently involve close coordination with finance, regulatory and commercial teams, ensuring alignment between corporate structures, compliance requirements and business objectives.

Clients consistently underline my proactive and pragmatic approach. Testimonials highlight my flexibility in addressing complex requirements and my ability to deliver solutions in a practical, business-focused manner. I have been described as “really proactive and professional,” with my support recognised as “crucial for liaising with and solving legal problems in relation to complex negotiations.” Such feedback reflects not only technical strength but also a results-driven mindset that clients rely on to advance their strategic goals.
