A Vivendi representative confirmed the upcoming executive get together, but didn't discuss the specifics of the meeting. Said meeting has taken place annually since 2005, and the rep noted it's intended as "a forum of exchange and discussion, not for quick-fix decisions or solutions."
Vivendi and Activision came together in 2007, creating Activision-Blizzard as a result of the merger. Vivendi sold three percent of its Activision stock in late 2011, but kept approximately 60 percent of its holdings. Since today's report, Vivendi's stock rose 3.7 percent in Paris markets.
Update: To help contextualize some of this super business-y madness, Wedbush Securities analyst Michael Pachter told Joystiq, "Some believe Vivendi is worth more if it is split up into various parts. The potential split doesn't really mean anything for Activision, other than a lot of shares on the market all at once. I don't think a sale is likely, as there are few potential buyers, if any. Instead, it makes more sense for Vivendi if they have Activision borrow a lot of money and pay a dividend of all of its cash. Spin it off to Vivendi shareholders." He added that he's not sure if the report is accurate or not.
