Nokia Networks reported a 20 percent year-on-year hike in its second-quarter revenues to €3.64 billion (US$5.24 billion) Thursday, helped by two months of revenues from the Motorola wireless infrastructure assets it finally acquired in April. (See NSN Finally Seals $975M Moto Deal.)

But that growth wasn't due only to the acquired lines of business. Parent Nokia Corp. (NYSE: NOK) noted in its earnings report that "excluding the acquired Motorola networks assets, Nokia Siemens Networks net sales would have increased 13 percent year-on-year."

That puts NSN's second-quarter revenues, excluding the Moto assets, at €3.43 billion ($4.93 billion) and the sales contribution of the Motorola lines at €208 million ($299 million) for May and June.

Just for fun: By extrapolating that figure, the new Motorola assets have a quarterly revenue run rate of around €310 million ($446 million).

The addition of the new assets has at least had one of the desired effects, as NSN's North American revenues leaped by 72 percent to €311 million ($447.3 million) in the second quarter. (See NSN Expands in North America With Moto Buyout.)

NSN's margins are still a concern, however. Its second-quarter gross margin was 26.6 percent, down from 30.8 percent a year earlier, while its operating loss was €111 million ($160 million), though that is an improvement from a year ago.

Its non-IFRS operating profit (before one-time charges) was €40 million ($57.5 million), giving it a non-IFRS operating margin of just 1.1 percent, down from 1.7 percent in the same quarter a year ago.

Nokia expects NSN to generate revenues in the range of €3.2 billion to €3.5 billion ($4.6 billion to $5 billion) in the third quarter, during which the equipment vendor's parents are expected to reveal their plans for the venture following their decision to remain the sole investors.
