I do wonder about the CEO's grand plan. She is giving felons permanent powers and hopes to sell them to the highest bidder. What makes her think she is going to be able to control them? Dr. King kept them in check precisely because the powers weren't permanent. They always needed to come back to him for another dose.
Some of them may try to use her as a broker for their powers, but many are just going to go out on their own.
Anyway, they wrapped most things up and set up the second season quite well - in the unlikely event that there is one. At least we weren't left with a huge cliffhanger. People can buy the whole season set and be happy that they have a relatively complete and self-contained story.
