I was looking for news on an IPO but couldn't find anything, but I did find this dated today Jan 22 2020:
Its good to see HL jumping of course, but this article suggests (to me at least) that their strong rebound is likely due to their own bottom line performance and may not be the result of anything to do with their ownership stake in Resverlogix.
Regardless of the reasons its good to see Resverlogix's biggest stakeholder doing well...
