Not sure it matters, but the earnings release says she was replaced by an investment banker from B. Riley. Purely speculation on my part, but could they be seeing what kind of bids they would get for a sale with him coming on board?
I actually wouldn't be surprised if they are the acquirer. They have a ton of cash and need to keep up a high percentage growth rate. This industry is down, but actually QSII's earning aren't nearly as bad as their peers.
