Timing of PR is determined when a transaction is completed, as there is a specified time period when the news needs to be released; it is not a situation that the company can decide, "We'll hold the bad news for 3 days and release today's good news now."
If the company could control the news, it would be better to release positive news first to build a stronger base before the bad news comes out. If bad news were to be announced first, there is a weak base, with many unanswered questions, to handle the negativity (extreme selling with SP plunging) as the eventual good news is not known and those matters will be in doubt. When released later, the good news will be ignored for all intents and purposes. But ...
... if all the news is good, then who cares about order of PR's.
