From growth companies to multinationals and leading institutions, we offer a wealth of expertise in corporate transactions to a diverse and innovative client base. Our advice is clear, pragmatic and, crucially, aligned with the client’s strategic goals.

Our experienced lawyers advise on every aspect of corporate transactions and leverage the firm’s full-service offering to provide business-critical advice in key areas such as tax, employment, UK and EU competition/anti-trust, regulatory, real estate, IT, data protection and IP issues.

Our market-leading strengths in IP and technology mean we are uniquely well-placed to counsel clients in dynamic sectors such as technology, life sciences and brands. We draw on our understanding of these sectors to advise corporate and institutional clients acquiring or evaluating IP and technology portfolios, helping them to secure commercially-relevant legal protections and to acquire, sell or invest with confidence.

We carry out both domestic and cross-border transactional work advising on private and public mergers & acquisitions, disposals, spin-outs, and corporate reorganisations. We also have considerable experience of advising on domestic and international joint ventures, helping our clients expand and develop their business into new areas and new markets.

With regard to finance transactions, we act for businesses raising finance as well as for the finance providers including venture capital firms, private equity firms and corporate venturing houses. We are recognised for our market leading expertise advising technology and life sciences growth companies at all stages of the evolutionary cycle of equity financing transactions including early stage financings, Series A and Series B, growth equity and pre-IPO cross-over finance. We also advise numerous equity providers in these sectors on their investments from Series A onwards and act for many of the world’s leading companies on their corporate venturing programmes.

Our debt experience includes advising on corporate borrowing and secured lending transactions, acquisition finance and debt refinance as well as venture debt and convertible equity instruments.

We also offer the full range of services for equity capital market (ECM) transactions and have experience in handling primary and secondary offerings on both the UK markets and NASDAQ from a UK perspective.

On cross-border transactions, we draw on a network of specialist lawyers from independent law firms around the world in order to provide a seamless service. A key differentiator of Bristows’ network as compared with that of “global brand” firms is our ability to choose the best firms for any particular transaction rather than being tied to one firm or office in each jurisdiction.
