By 2016 Peck predicts an explosion in revenue up to US$6bn, generating US$2.3bn in pre-tax earnings.
Those calculations form the basis of his advice that Facebook is worth "as much as US$5-US$6bn".
Despite already having a $1bn bid turned down, Peck expects Yahoo to make an improved offer if it doesn't want to "risk becoming a marginal player in this rapidly growing space".
And he believes a significantly-improved offer would secure the site for Yahoo.
"When it comes down to it, we think the price tag is the ultimate factor for a transaction to materialise," he said.
