Motorola offered a estimate that lowered expectations for its Q4 2011 earnings earlier this month, and it’s now out with the final numbers, reporting net revenues of $3.4 billion and a GAAP net loss of $80 million. That’s a swing in the opposite direction from $80 million in net earnings during the same quarter a year ago, although the company did achieve the “modest profitability” it had promised on a non-GAAP basis, reporting earnings of $61 million by that accounting standard. Its earlier estimates of device shipments for the quarter also proved to be on the mark, with the company confirming that it shipped 10.5 million mobile devices in total, 5.3 million of which were smartphones. Mobile device shipments for all of 2011 totaled 42.4 million, with 18.7 million of those being smartphones.

As for the company’s efforts to break into the tablet business, it says it “shipped” 200,000 tablets in Q4 and an even one million during the year, although there’s no word on actual sale figures to consumers. Motorola’s Sanjay Jha also says that the company remains “energized” about the proposed merger with Google, which is still expected to close in early 2012 (it’s also, incidentally, precluded an earnings call for today).
