SJ Berwin has posted 2.5% revenue growth for 2012-13, with profits per equity partner (PEP) set to fall by around 10%.

The UK top 20 firm has announced unaudited turnover of £184.6m for the last financial year, up on the £180.1m took in during 2011-12.

PEP has not yet been finalised; however, it is expected to have fallen around 10% on last year's figure of £635,000, putting it in the region of £570,000. Net profit, however, is understood to have marginally risen.

The results come after period of significant investment, including 13 lateral hires and a launch in Luxembourg in January this year. The firm cited its London, Germany and Brussels offices as standout performers, while the regulatory, corporate, funds and energy and infrastructure practices saw the most growth.

Senior partner Stephen Kon said: "We will continue to invest in our platform, ensuring we are where our clients need us, focusing on growing our emerging markets offering and further strengthening our corporate, litigation and energy and infrastructure practices."

The news comes with the firm currently in merger talks with Asia-Pacific firm King & Wood Mallesons. Last weekend (8-9 June) partners informally discussed the potential tie-up, which would be structured as a Swiss verein, at their annual retreat in Marbella.
