After four years of rising revenue, McDermott Will & Emery saw its gross revenue slip in 2015, while profits rose 3.3 percent for the firm’s somewhat diminished equity partnership.

The Chicago-based firm brought in $891.5 million in revenue last year, a modest decline of 0.9 percent from the $900 million it posted in 2014. The firm’s revenue still sits below prerecession levels, when it peaked at $978 million in 2007.
