Insight: British American Tobacco

We assisted the lead banks on a USD 25 billion acquisition loan facility for British American Tobacco, to back the USD 49.4 billion acquisition of the 57.8% stake in U.S. peer Reynolds American Inc. which it did not already own. This was the largest deal in the European syndicated loan markets in 2017.

As part of our global Corporate and M&A practice, you’ll advise some of the world’s most successful companies, commercial and investment banks and private equity firms, on all aspects of commercial law and corporate finance. Mergers and acquisitions are the bedrock of our work; you can expect to tackle everything from public takeovers, private M&A and international equity offerings, to joint ventures, disposals and corporate restructurings – as well as day-to-day regulatory matters. Our lawyers combine excellent transactional skills with specialist expertise in areas such as antitrust, commercial, environmental, IP, tax, employment and pensions. We advised on one of the top five highest value, cross-border M&A deals in 2020 (Mergermarket) and are first globally for cross-border M&A by value (Bloomberg Q4 2020).

Insight: Liberty Global

We assisted Liberty Global on its GBP 31.4 billion joint venture with Telefónica to merge Virgin Media and O2’s fixed, broadband and mobile businesses in the UK.


Having the opportunity to advise on complex, high-profile transactions like the Virgin Media/O2 merger is one of the main reasons I became a corporate lawyer and why I chose to join Allen & Overy. The collaboration between various teams within Allen & Overy, the client and the other side was really impressive to observe and a privilege to be a part of, particularly as the serious work began very shortly after the UK went into lockdown #1, which meant that due diligence, drafting, negotiations and signing all had to be conducted completely remotely at a time when most people were still getting to grips with working from a laptop on their kitchen table for the first time.

International Capital Markets

With over 550 lawyers based all over the world, our International Capital Markets Team is at the heart of the world’s banking and financial markets. We enjoy a top-tier position across the full range of capital markets product lines and we’ve played a big part in almost every major development in our field. Rapidly changing economic, political and regulatory conditions have made the last few years challenging and we have helped clients address the fallout from several sovereign debt crises. As our focus shifts towards big-picture, long-term projects, we are increasingly working with colleagues from other practice areas to develop innovative solutions that incorporate complex financing techniques.

Insight: MarginMatrixTM

We developed a market-leading IT solution to help our clients comply with the mandatory variation margin rules that now apply to the USD 500 trillion OTC derivatives market. MarginMatrixTM covers global regulatory requirements, template development, data collection, data scrubbing, negotiations, automatic drafting, delivery of legal opinions and the import of data back on the client’s systems for business as usual. MarginMatrixTM provides process efficiencies and economies of scale that no individual client could match on its own. We acted for eight global investment banks, and between them, these eight clients have required over 25,000 negotiations.

Everyone at Allen & Overy takes real pride in doing their job well. It creates an inspiring atmosphere.

Insight: Covid-19 and the workplace of the future

At the outbreak of Covid-19, leading corporates and financial institutions turned to us to advise on the unprecedented employment aspects of the pandemic’s impact. As countries went into lockdown, we advised them on how to manage their workforces and we are working with them to establish what their ‘new normal’ will look like, ensuring they are covering all the relevant issues and that they have a holistic picture of their risk position. As we come out of the pandemic, we are continuing to advise on mandatory vaccinations/testing, as well as how businesses can move effectively to large-scale, hybrid working models.

People issues are at the top of board agendas and our clients come to us for strategic insight and guidance on the most sensitive and complex HR matters.

Insight: South Stream Transport

We worked with South Stream Transport, part of Gazprom, in an ICC arbitration with Saipem relating to a gas pipeline from Russia under the Black Sea into Europe. The case was one of the largest construction arbitrations of recent years.

I really enjoy the fight of litigation: strategy, tactics, intensity and especially the highs/lows of winning and losing.‎ There's no feeling quite like it.
