Osborne Clarke (OC) has kicked off this year's results season by posting a 15% rise in global revenue for the 2014-15 financial year.

The figures show global revenue for the year to 30 April 2015 was €195m (£140m), up from €169m (£121m), while UK revenue grew by 9% to £96.5m, up from £88.4m, according to a statement by the firm.

OC UK managing partner Ray Berg (pictured) said it had been a "stunning" year for the firm, adding that it was a "privilege to be able to announce such great results so soon".

Revenue from clients in OC's eight chosen sectors, which the firm said it would focus on in its five-year strategy earlier this year, accounted for 93% of its UK revenue.

Those sectors are digital business, energy and utilities, financial services, life sciences and healthcare, real estate and infrastructure, recruitment, retail, and transport and automotive.

The firm's figures for profit and profit per equity partner are set to be finalised in the next two to three weeks.

Deals that the firm has worked on during the year include Carphone Warehouse's £3.6bn merger with Dixons Retail and Patisserie Valerie's £170m initial public offering.

The firm also opened an office in Amsterdam and established a strategic alliance with Hong Kong firm John Koh & Co during the year.

In 2013-14 OC reported an even larger increase in revenue as it climbed to £142m from £112.8m, a rise of 26%.

Those figures resulted in all UK staff being awarded a year-end bonus.

The firm is understood to be in the process of assessing the results for 2014-15 in light of its bonus structure to see if a payout will happen again this year.

Looking forward Berg said: "Among other initiatives, we're looking at increasing process efficiencies, deepening our diversity programme and increasingly internationalising our client relationship management programme.

"Clearly we're not resting on our laurels."
