you've just described 90% of all publicly traded companies. lol.
My all time fav story is ISRG - split adjusted it ran from pennies to over $1000/share. they had a monopoly on FDA approved soft tissue surgical robot until this year. they had been literally raping hospitals forever with an old outdated robot, and selling extremely expensive replaceable surgical instruments for it. The hospitals all had to pay because there was no other FDA approved laparoscopic / soft tissue robot.
now that there is a new competitor this year with a newer robot, monopoly is over- just about all of the execs started cashing out blocks of shares right after the last ER. Quite hilarious. the party is ending. but hey i give them respect for creating the monopoly and racket. the sad part is if they were not so greedy they could have remained on top forever by updating their robot and making it more cost effective. they refused to meet any customer requests for things like haptic feedback and reusable instruments, head tracking, which the new competitor robot has (TRXC). obviously, the ISRG CEO should be fired for incompetency but he'll have a big golden parachute.
