Agree - very disappointing and frustrating.
So far he's sold ~ 37.5m shares or ~ 27.5% of his holding prior to the selloff which started last November.
IMO he has committed to the board for an orderly sell down and his selling patterns/prices so far suggest that.
Problem is if his intention is to sell out completely that will make it more difficult to attract money with another CR in the short to medium term.
I would hope/assume he isn't allowed to sell during a capital raise period.
The other problem is at the current sell rate in would take the remainder of 2023 to get out out completely.
This means the major milestones announcements we are expecting to see this year may be sold into as everyone knows the prince will be selling.
Let's see if he sells in three weeks prior to such an announcement or after ....

Some positive news: (Via Google Translate)

I don't know if Altech Batteries Limited (ATC) subscribed ( I hope they didn't)
ATC holds ~ 29% of Altech Advanced Materials AG.
It means they can pay for their share of the pilot plant and Cerenergy BFS and maybe finally make a payment to us on the amount outstanding for ATC selling them the 25% of AIG. ()
