At Yahoo, the long running courtship has lasted at least as long as this year, and is internally referred to as "Project Fraternity." Leaked documents in our possession state that an early offer was $37.5 million for 5% of the company (a $750 million valuation) back in Q1 2006. This was rejected by Facebook.
Things really heated up mid year. Yahoo proposed a $1 billion flat out acquisition price based on a model they created where they projected $608 million in Facebook revenue by 2009, growing to $969 million in 2010. By 2015 Yahoo projects that Facebook would generate nearly $1 billion in annual profit. The actual 2006 number appears to be around $50 million in revenue, or nearly $1 million per week.
These revenue projections are based on robust user growth. By 2010, Yahoo assumes Facebook would hit 48 million users, out of a total combined highschool and young adult population of 83 million.
Our sources say that Facebook flatly rejected the $1 billion offer, looking for far more. Yahoo was prepared to pay up to $1.62 billion, but negotiations broke off before the offer could be made.
These documents are now a couple of months old, and both Yahoo and Facebook may have changed their views on a possible deal substantially in that time.
