Now that the proposed trans-Atlantic merger between O’Melveny & Myers and Allen & Overy has officially fizzled, a deal between two Midwestern regional firms could turn out to be the biggest law firm combination announced in 2019.

So far, Friday’s news that Cincinnati-based Taft Stettinius & Hollister will merge with Briggs and Morgan—a Minneapolis-based firm with about 135 lawyers—marks the largest law firm acquisition of the year. That’s a far cry from 2018, when five much larger deals had already been announced by early summer, according to data collected by ALM and Altman Weil.
