It's human nature to push off bad news. It is also better to release bad news after close of business on a Friday, so that investors can absorb the shock, be diverted by weekend activities and be in a more forgiving mood by Monday morning.
Plus, that gives PT a chance to issue another fluffy Monday morning PR to help investors "get over" not seeing any revenue, or seeing new toxic notes show up. Maybe talk about how that new "Volve" is working out.
