Karlo Siirala

Partner, Member of the Finnish Bar, LL.M.

I advise private equity firms, financial investors, corporates, growth companies, founders and management teams on various types of corporate transactions, including mergers and acquisitions, buyouts, exits, and growth and minority investments. I have significant experience in executing complex cross-border transactions across a range of business sectors, with particular experience in the technology and life sciences sectors and regulated fields, such as banking, insurance and financial services.

I also advise fund managers and investors on a wide range of matters related to private investment funds, such as fund formation, co-investment and consortium arrangements, fund investments and secondary transactions.

I earned my law degree from the University of Helsinki. In addition, I hold an LLM degree from Columbia Law School, where I was recognised as a James Kent Scholar for outstanding academic achievement. I also have gained international experience through my secondment to a leading US law firm. I have been recognised as a Rising Star for Corporate/M&A/Private Equity in Finland in the IFRL1000 Rising Stars Expert Guide 2022.

I regularly lecture at law schools and client seminars on topics related to corporate law and mergers and acquisitions.
