Samsung's numbers aren't just strong, but record-breaking and even better than the company expected when they announced the estimated results a few weeks ago. Samsung posted an operating profit of 5.3 trillion won ($4.72 billion USD) with sales of 47 trillion won ($42 billion USD). 5.3 trillion won in profit is a 76% increase over Q4 2010.
Samsung’s mobile business specifically posted an operating profit of 2.6 trillion won ($2.3 billion USD) in Q4 because of huge mobile phone shipments of a record 35 million units. Unfortunately, even with the record Q4, and a rise in full-year revenue, Samsung's full-year net profit of 13.7 trillion won was down 15% year-on-year.
