Highly professional and qualified team. O2 lawyers are excellent at handling complex cross-border M&A transactions. They have strong reputation as notably active in headline inbound M&A transactions and joint venture projects within Russia and abroad.

I’d like to praise great O2 team for the splendid work they did. They are highly professional and result-orientated, fully understand client’s needs and are always guided by these needs. They are able to handle complex and sophisticated domestic and cross-border M&A transactions. 

I’d like to mention highly skilled, internationally qualified partners and associates of O2 Consulting. In our case their English law expertise came in handy. We needed the transaction documents including parallel share purchase agreements under English law and Russian law and the call and put option agreements to be prepared. They managed to provide all conditions for the transaction with a complicated structure and with a series of closings. The solution they offered included a unique set of Russian and English law governed back-to-back put and call options combined with amendments to the effective shareholder’s agreement.’

They provided us very high quality services. All O2 Consulting lawyers I worked with established themselves as competent, UK-qualified, well-respected corporate and commercial experts with unique understanding of the clients’ needs and goals, capable of perfect drafting and communication

Karen Shakhnazarov’s excellent commercial acumen, combined with more than 20 years of legal expertise and a charismatic personality, makes him a partner to go for complex M&A transactions and difficult negotiations.
