Softbank is hitting the whole Silicon Valley looking for people to prop up it's failed investment. This was never a growth stock and they have killed any value with paying 50% over asking price at the time in 2016. With inflation I wonder are they even breaking even at 40-50 billion. The only reason they would invest is if they want to ensure control is never lost again, but even at 10% if all the other shareholds vote to sell you could find yourself outnumbered on the board.
I'd love to be a fly on the wall of those board meetings though, with people willingly trying to choke ARMs development and innovation so they can negotiate tiny royalties on their architecture licenses. They have pissed off every customer seemingly in a desperate bid to inflate revenue, if only those customers realised the middle-manager bozo fest they have been helping prop up whilst engineers walk out the door.
It seems here in Cambridge most of the employees are only sticking around for IPO, those that haven't left that is, but then again most of them haven't had any career development the past few years and think other companies want their out of touch skillsets of jockeying JIRA boards and calling it innovative engineering. I've seen single handedly the delusion of these types of engineers quickly finding out that they aren't as talented as ARM tells them.
