If he got pushed out, then this is good news. However, if he is resigning on his own terms as "he pursues new opportunities in his home state of Florida" according to the release, then it's a bad thing because it means that even he has realized that this is a sinking ship. We won't know the real answer because many times, an exit strategy is phrased a certain way on purpose.
I assume since he is staying to help with the transition and they have an outside replacement already to go, that this has been in the works for sometime. Its usually a bad sign when your CFO resigns just when your business is on the verge of a major expansion, but I see no sign of him selling his stock up to now, so maybe he's just burnt out and he didn't feel he could handle the complex demands of global finance.
That's just a ridiculous comment. How is this indicative of a sinking ship? You bring in a new CFO from a prominent company. Plus the timing clearly indicates that this move was in the making for a long time. Nothing negative to read here.
Then why would he leave now? Why not hang out for another year or two, when the company is clearly ready to take off? I think (hopefully) he was forced out for someone more experienced. The new guy looks like a sharp CFO.
