The story of Nissan's quarter in a nutshell

Revenue fell, operating income fell, but net income and vehicles sold both rose. How did that happen?

A couple of big factors hurt revenue and operating profit. First, like Japanese rivals Toyota (TM -1.20%) and Honda (HMC -0.87%), Nissan was hurt by a rise in value of the yen versus the U.S. dollar and euro. Dollars and euros earned abroad were worth fewer yen during the quarter than they were a year ago. Nissan said that shifting exchange rates alone took a 81.6 billion yen ($699 million U.S.) slice out of its operating profit for the quarter -- a hefty bite.

The exchange-rate swings accounted for most of the revenue drop, but operating profit was further hurt by an 87 billion yen ($768 million U.S.) increase in "marketing and selling expenses." Translation: incentives, particularly in the U.S., where a year-over-year increase in discounts hurt operating income by 67.2 billion yen ($593 million U.S.). The incentives helped boost sales, but at the expense of operating profit. 

Why did Nissan raise its incentives? The U.S. market is still healthy, and Nissan's car models compete well. But like rival Toyota, Nissan's model portfolio is still heavily weighted toward sedans, while market preferences have shifted toward the newer generation of car-based crossover SUVs.

Nissan has had to boost discounts to draw more buyers to its sedans while it works to increase production of its SUV models. Trucks and SUVs accounted for about 49% of Nissan's U.S. sales last year versus about 61% of the overall market.

Meanwhile, net income increased year over year, largely because Nissan's year-ago net result was hit by a big one-time charge related to recall costs. 

Also in the quarter: Nissan took control of Mitsubishi Motors

Nissan completed the purchase of a 34% stake in Mitsubishi Motors (MMTOF 2.01%) in October. Under Japanese law, that's a controlling stake, and Nissan CEO Carlos Ghosn became Mitsubishi's chairman soon after. The companies are currently working to integrate Mitsubishi's automotive operations into Nissan's alliance with French automaker Renault (RNSDF 6.90%)

Including Mitsubishi's sales, the Nissan-Renault alliance sold 9.96 million vehicles in 2016, making it the world's fourth-largest automaker.
