Arntzen Grette is a leading Norwegian M&A adviser, handling the full range of transactional work, including public and private acquisitions, mergers and demergers, joint ventures, reorganisations, and divestments. The team combines strong transactional capability with deep sector knowledge, particularly within energy and technology.
We act for Norwegian and international corporates, private equity funds, investment firms, and major industry players. The team is recognised for navigating complex regulatory environments and structuring transactions that balance innovation, compliance, and commercial value.
Recent work includes major transactions in both traditional oil and gas and the rapidly expanding renewables sector. We have extensive experience with large-scale acquisitions, cross-border investments, and restructurings involving intricate regulatory frameworks and project financing.
Our interdisciplinary approach is a key strength. M&A specialists collaborate closely with experts in capital markets, competition, tax, financing, employment, and dispute resolution to ensure each transaction is managed strategically and efficiently.
We are known for maintaining deal momentum, identifying and mitigating risks early, and delivering pragmatic, value-driven advice. The team also advises private equity clients on portfolio transactions, fund structures, and exits, offering balanced insight from both buy- and sell-side mandates.
