Analysts surveyed by FactSet expected Goldman to earn $4.32 a share on $7.66 billion in revenue.

For the full year, Goldman reported a profit of $8.08 billion, or $17.07 a share, up from $7.73 billion, or $16.34 a share, last year.

Goldman's compensation expenses, typically the firm's largest operating expense, were flat for the year at $12.69 billion.
