Well, the known mid-range publishers that went completely or partially bust is not that large. THQ, Atari, Majesco, and Midway come to mind, but neither had a studio buying rush beforehand as far as I remember, but Majesco and THQ bought up plenty of licenses before going under, so that might be. I remember Majesco focusing and investing heavily at first into the PSP and the Advent series but neither worked out for them.
I checked, and I think the Publisher was... THQ!
THQ bought a ton of studios before the financial crisis (6 studios alone in 2006), but got hit badly by the crisis. And since they burnt all their money in acquisitions, they didn't have any reserves for the crisis, and had to file for chapter 11 in 2012. So maybe that just comes with the name.
Although Nordic games already was on a shopping spree long before they acquired the THQ brand name for themselves. And it's long enough to even warrant it's own Wikipedia page: https://en.wikipedia.org/wiki/List_of_acquisitions_by_THQ_Nordic
Also funny how this closes the circle: Their first acquisition (still just as Nordic games) was JoWood, the owner of the Gothic brand. Now with Piranha Byte, they also have it's creators.
