Despite being a record year for law firm mergers, 2013 will not see McKenna Long & Aldridge and Dentons sit down with one another at the Thanksgiving dinner table. The Am Law 100 firms confirmed Tuesday that they will remain separate entities a little more than a month after announcing they were in discussions about a potential combination.

McKenna had postponed voting on a merger with Dentons several times, according to reports by sibling publication the Daily Report, with a final vote that began this weekend due to conclude Tuesday. But voting was halted by midday once McKenna’s management, which had endorsed the deal with Dentons, realized it could not persuade a supermajority—or partners holding two-thirds of equity in the firm—to vote in favor of a merger, says a senior Dentons partner who briefed The Am Law Daily on the matter early Tuesday afternoon.
