Boards and sponsors bring their most consequential transactions to Thornhill, trusting us to deliver deal certainty, sharp commercial judgement, and outcomes that hold up to the closest scrutiny.
We advise on complex and cross-border public and private transactions, combining corporate expertise with leading specialist teams in finance, tax, competition and regulation. We act for bidders, targets, sponsors and financial advisers in roughly equal measure, giving us a balanced view of how transactions are negotiated from both sides of the table.
Our London, New York and Hong Kong teams work together as a single deal team on cross-border matters, and we routinely draw on colleagues in Financial Services Regulation, Competition and Tax so that regulatory considerations are addressed from the outset rather than discovered midway through a transaction.

Our Difference
Advisers to both sides
The majority of our M&A matters span more than one jurisdiction, and our London, New York and Hong Kong teams work as a single deal team rather than local hand-offs.
Built for cross-border complexity
The majority of our M&A matters span more than one jurisdiction, and our London, New York and Hong Kong teams work as a single deal team rather than local hand-offs.
Regulatory fluency as standard
Our M&A partners work as a matter of course alongside colleagues in Financial Services Regulation and Competition, so regulatory risk is identified early rather than discovered late.
A steady hand under pressure
Public company transactions move on tight, immovable timetables, and our teams are structured to give boards clear, decisive advice when it matters most.
Long-term client relationships
A significant proportion of our M&A instructions come from clients we have advised on more than one transaction, a mark of the trust we aim to earn.
