I imagine that when a company has been in bankruptcy and is sold, that means that a lot of people are going to need to come together to figure out how to improve processes, cut costs, and avoid going into bankruptcy again.
My company did so well last year that we are in the process of being sold and merging with another company. The process started back February or March of this year and the sale is still going through the approval process and the executives directors have been in meetings for months. After the sale goes through, it will take a while to integrate, learn to merge and update processes, notify and manage customer transitions, etc. The sale should go through soon, but the transition process may take years before it's fully compelted.
