The search giant is down more than 9% after reporting 4Q earnings of $8.22 a share, below the Street’s $8.41 consensus forecast. Net profit came in at $2.7B, up 6.4% vs the same period last year, on revenues of $10.6B, up 25.4%. But when ad commissions are taken out, the revenue figure drops to $8.1B, which is short of what most analysts expected. Google-owned sites accounted for 69% of total revenues. Although investors were disappointed, CEO Larry Page was ebullient: “I am super excited about the growth of Android, Gmail, and Google+, which now has 90M users globally. … I’m very excited about what we can do in 2012 — there are tremendous opportunities to help users and grow our business.” He declined to tell analysts how many Google+ users he expects to have a year from now.
