All that info is pretty easy to find in HMBL/TSNP at the time PR's printed numerous places. If I recall, it was 550 Million. I think Nov 2020 timeframe.
They didn’t cancel any preferred shares, the 551 million commons (pre split #) that Brian acquired along with the 7 million Pref A (for $40K) were returned to the company and cancelled. The 318 million commons (pre split #) that Brian acquired in the open market prior to Nov. he still owns. He had said he was going to convert into Pref B...but he has not. His post split 91 million commons (365 million pre split) are still owned by him with no conversion.
