On November 19, 2021, in the course of a conversation on a different topic between Mr. Spencer and Mr. Kotick, Mr. Spencer raised that Microsoft was interested in discussing strategic opportunities between Activision Blizzard and Microsoft and asked whether it would be possible to have a call with Mr. Nadella the following day. Mr. Kotick agreed to participate in such discussion. Following this call, Mr. Kotick promptly reported the conversation to Robert Morgado, the lead independent director on the Activision Blizzard Board of Directors, and Brian Kelly, the chairman of the Activision Blizzard Board of Directors. Messrs. Kotick and Kelly subsequently spoke with Allen & Company LLC, which we refer to as "Allen & Company," which had provided strategic financial advice to Activision Blizzard on other occasions, regarding the call with Mr. Spencer.
In a call on November 20, 2021, between Messrs. Kotick and Nadella, Mr. Nadella indicated that Microsoft was interested in exploring a strategic combination with Activision Blizzard. Following this call, Mr. Kotick promptly discussed the call with Messrs. Morgado and Kelly and, thereafter, with a representative of Skadden, Arps, Slate, Meagher & Flom LLP, outside legal counsel to Activision Blizzard, which we refer to as "Skadden."
On November 22, 2021, a call was held with Messrs. Spencer, Kotick and Kelly, during which call Mr. Spencer noted that, while Microsoft already had a significant amount of information about Activision Blizzard and its business as a result of the commercial relationship between the companies, Microsoft would need additional information regarding Activision Blizzard's long-range financial plan and prospects in order to advance its analysis. Subsequently, Messrs. Kotick and Kelly indicated to Mr. Spencer that Activision Blizzard was not willing to provide such information without an indication of the proposal that Microsoft would be prepared to make that could then be shared with the Activision Blizzard Board of Directors to gauge the Board's level of interest in engaging in additional discussions. Following this call, Robert Corti, chair of the Audit Committee of the Activision Blizzard Board of Directors, was also informed of Microsoft's expressed interest in potentially pursuing a transaction.
On November 26, 2021, Mr. Spencer again spoke with Messrs. Kotick and Kelly, indicating that, based on the information available to Microsoft, Microsoft was preliminarily considering making an all-cash acquisition proposal for Activision Blizzard at $80.00 per share. Thereafter, Messrs. Kotick, Kelly, Corti and Morgado discussed potential ranges at which the full Activision Blizzard Board of Directors may be willing to consider an acquisition proposal taking into consideration, among other factors, Activision Blizzard's historical trading prices, selected research analysts' estimates for Activision Blizzard and relative trading multiples of Activision Blizzard and its peers.
