Expertises

Corporate/M&A
Mergers and acquisitions are among the most transformative decisions a business can make – whether driven by ambitions for growth, entry into new markets, evolving industry dynamics or long-term investment objectives. These transactions demand clear insight and the ability to navigate legal and regulatory complexity across jurisdictions.
Capital Markets
Whether you want to raise capital through equity, debt or alternative forms of financing, you need to thoroughly understand the sector and the legal ins and outs of domestic and international capital market regulations.
Private Equity
Houthoff advises private equity clients on transactions, acquisitions, financing and structuring. Our team offers strategic and legal support from entry to exit.
Governance
Governance and supervision within large corporations and (semi-)public institutions require careful consideration. Supervisory board members often find themselves in a complex position: they must remain sufficiently involved in the company’s management while also maintaining their independent role. Striking the right balance is essential, especially when the pressure is high and the stakes are significant.
ESG & Sustainability
Behind the daily headlines on sustainability and environmental, social and governance (ESG) issues hide complex challenges such as permitting, subsidies, funding and reporting obligations. These matters affect the expectations and demands of all corporate stakeholders.
SPAC
A SPAC (Special Purpose Acquisition Company) is an alternative way of raising capital through an initial public offering, before acquiring an operating target company.
