Both Bcom and Qcom were in talks for a merger/getting bought long before today's news. Quarterly earnings report is always Wednesday and all hands has ALWAYS been the coming Friday. Every time. This time we did not having all hands meeting. All hands meeting was not scheduled for today because it would be chaotic. Announcement/leak from Bcom was preplanned.
Qcom execs want this deal to happen in order hedge possibility NXP deal won't happen; it is very likely it won't happen. Expect next all hands just to prep you what's going to happen next.
NOTE: this is all my guess. Having both acquisition announcement and no meeting is too convenient to be coincidental
