Not to suggest that AMD's primary reason for purchasing ATI would be to deflect from their poor Q2 results, as if true, talks would have likely been ongoing for many months or more, but delaying an annoucement or at least delaying the more public process of announcing takeover talks with shareholders and the ensuing, wider media coverage until shortly after the poor market reaction to their recent results, may have some advantages.
I thought that if an annoucement were to happen, it would be before the last CC, to soften the earnings blow and shift attention to the new dynamic such a move would bring. A couple of
ifs ahead, but if the market reaction to the start of this whole process via an official public annoucement (on Monday, if true) is positive or tends to improve as the process draws out over the coming months (assuming it does) and more details of the future relationship/combined entity become clear, it should add a lot of buzz to AMD over the difficult coming months against a resurgent Intel product line-up and price gouging and deflect from short-term financial concerns simply because it would be such a significant investment in long term capability and diversification. Whether it's the right thing for both companies at this time is another matter!
As noted in the CNN piece, it is rather interesting that none of the analysts enquired about the rumours at either of the last AMD or ATI CC's -- even if they likely expected the standard, "we don't comment on rumours" or similar response, the recipient's reaction could have been somwhat telling -- well, at least it would have given us some more vagaries to speculate on!
