RPC has defied the continued economic downturn to post a 20% hike in turnover in 2012-12, with the expansive firm's revenue rising from £68m to £82.1m.

The results come after the firm's revenue climbed by 13% during the previous financial year, meaning fee income has soared by 36% over the last two years compared with a 2010-11 equivalent of £60.3m.

Profit per equity partner (PEP) has still to be confirmed, so it is unclear what impact the firm's recent expansion drive has made on profits.

According to the firm, the rise in turnover is practice-wide, with transactional and advisory teams, as well as litigation, putting in strong performances.

RPC, which saw PEP rise by 10.6% in 2011-12 to £354,000, opened in Bristol in January 2012 with the hire of a 28-strong team from CMS Cameron McKenna, while August last year saw the launch of a Hong Kong base through the addition of a five partner team from Clyde & Co. Its last international move was in October 2011 when it opened in Singapore in October 2011.

More recent hires have included a three-partner corporate team from Wragge & Co in January this year, while March saw the firm secure the services of SJ Berwin corporate partner Anthony Shatz and DLA Piper IP partner Mark Crichard.

RPC managing partner Jonathan Watmough (pictured) said: "Clearly we're very pleased with these figures, not least because the lion's share of this growth is organic, with the expected uplift from our recent expansion in Asia and the UK yet to flow through.

"We could see as early as the year before last that strong momentum was building, and that many of the string of strategic investments that we'd made between 2008 and 2011, coupled with our fundamental reengineering of the firm, were starting to pay off significantly.

"And we've managed to achieve this growth without diluting the sense of teamwork and collegiality that derives from our all equity structure – an aspect of our culture that we defend ferociously."

Confirmation of RPC's strong results comes on the same day that Clydes announced a 17% boost in turnover and a 5% rise in PEP.
