I believe you are right that these are not SEC safe harbor pre planned compensation type sales because the Form 4 carries an "S" code, which is an open market sale.
I don't have a problem with them giving themselves a small bonus for all the work they do to build shareholder value, but I am a little concerned that the sale was so soon after the conference call as customary "blackout periods" for no insider trading usually encompasses 60 days prior to the material event as well as several days afterward.
It was a Friday, after hours , they all sold exactly the same time on march 1st, it is def. not sketchy and is normal pre scheduled. If this was done manually or as a sketchy thing it would have happened at noon a few days ago "the 25 spike".
