Top 30 International Firms in London

There are two new entries into this year’s table of the top 30 US firms in London by revenue.

Out go Arnold & Porter and Bryan Cave and in come Morrison & Foerster and O’Melveny & Myers, the latter like the proverbial rocket.

It is only three years since O’Melveny kick-started its UK offering by recruiting two private equity partners, Matthew Hudson and John Daghlian, the latter from SJ Berwin.

Since then, aided by the boom in private equity, the office has mushroomed.

Although still small at partner level, with only seven
currently on board, O’Melveny’s high leverage (the total lawyer headcount in the office is 50) has helped secure it a place among London’s leading US firms in record time.

Record growth is also on display at the other end of the table. As reported by The Lawyer (26 February), Mayer Brown Rowe & Maw and White & Case are the fastest-growing US firms in London, with the former’s UK revenue up by an impressive 21.8 per cent, from $145m (£79.67m) last year to $176.64m (£96m) and the latter’s up by a standout 38 per cent to $172.2m (£93.59m).

There is no doubting that 2006 was a boom year for US firms in the City. But for some, it was just that bit better than for others.
