CMS saw revenues across the group rise 5.1% during 2012, with net profit also climbing across the network of 10 law firms.

The network, which includes CMS Cameron McKenna in the UK, CMS Bureau Francis Lefebvre in France and CMS Hasche Sigle in Germany, saw total revenues climb to €837.7m (£679.3m) for the financial reporting period ending 31 December, up from €797.3m (£646.5m) in 2011.

Net profit rose 4.5% from the same period in 2011, with partner count standing at 768. The firm declined to provide a profit figure.

It is not yet clear how much revenue the UK arm contributed, with the firm so far declining to provide a geographic breakdown. Last year the UK arm posted revenues of £227.6m – 1.2% up against a 6.8% climb in profits per equity partner to £534,000 for the financial year ending 30 April 2012.

Announcing the groupwide turnover, CMS said that activity was particularly strong in the energy, life sciences, technology, media and telecoms (TMT) and financial services sectors.

CMS executive chairman Cornelius Brandi said: "This strong performance, which has been achieved despite the global economic downturn, is confirmation that the CMS model is the right one, allowing us to provide clients with the service they require on the best terms available."

Deal highlights included working with Telefonica Deutschland on its €1.5bn (£1.3bn) initial public offering, the largest flotation in Germany in the past five years, and representing Societe Generale on its €50bn (£43bn) Euro medium-term note programme.

The CMS group employs 2,800 lawyers across 54 offices in 29 countries. During the 2012 calendar year it opened in Barcelona and Dubai and expanded its Beijing team to 14 lawyers.

However, the UK arm launched a redundancy consultation in January this year which resulted in 37 jobs being cut including lawyers, secretarial and support roles.
