A little more than a year after a potential merger between Dentons and McKenna Long & Aldridge fell through, the two Am Law 100 firms are once again looking to combine operations.

McKenna Long’s partnership is on the verge of finally voting on a tie-up with Dentons, according to four sources briefed on the matter. The two firms discussed a deal throughout the fall of 2013, but a vote shortly before Thanksgiving was halted amid mounting opposition by some partners in McKenna Long’s powerful government contracts practice. As noted by sibling publication the Daily Report, any deal requires the approval of a two-thirds majority of McKenna Long’s equity partnership, a vote weighted by equity points.
