After remaining flat between 2011 and 2012, Pittsburgh-based K&L Gates saw its revenue grow by about 9.3 percent in 2013, a year that saw the firm’s financials impacted significantly by its Jan. 1, 2013, merger with Australia-based Middletons.

The firm’s gross revenue rose from about $1.06 billion in 2012 to $1.159 billion in 2013, with a larger chunk of that figure being generated by its overseas offices than had been the case the previous year.
