Mergers & Acquisitions, Corporate and Equity Capital Markets

Joint Managing Partner, Head of Transactions

Since helping set the firm up in 1998, Stefanie Yuen Thio now heads its transactional practice, where she is able to holistically support clients across all areas of her expertise, including public mergers & acquisitions, capital markets, private equity transactions and corporate governance.

Stef is a people person, which has not only built her a formidable network of contacts, but has also underpinned her strategic abilities in boardroom battles. Deeply invested in every relationship, Stefanie's unique personality and her proficiency in English, Mandarin and Cantonese have won her clients the world over, from the United States and Europe to Mainland China and Hong Kong.

Beyond the boardroom, Stefanie's interests extend to community causes. In 2022, she founded SG Her Empowerment Limited (SHE), a civil society organisation with Institution of Public Character status dedicated to women's empowerment. She is also an active and outspoken commentator on topics she is passionate about, regularly quoted and published in the news media on a broad range of subjects, from gender equality to governance in Singapore's listed companies.

In 2025, she was appointed Singapore's Alternate Representative to the ASEAN Intergovernmental Commission on Human Rights (AICHR). She was also appointed a member of the Monetary Authority of Singapore's (MAS) Corporate Governance Advisory Committee, where she chairs a sub-committee reviewing the Code of Corporate Governance (CG Code). Stefanie is the Chairperson of ESR REIT, an industrial real estate investment trust listed on the Mainboard of the Singapore Exchange Securities Trading Limited.
