Shares of Nokia (NOK 0.28%) found a crystal-clear wavelength on Thursday, Jan. 25. The Finnish provider of wireless phone network systems and related services reported fourth-quarter earnings early in the morning, sending the stock as much as 12.6% higher after the market open. The raw results were far from impressive, but management made up for the weak financial numbers with bullish commentary on a leaner operating model and improving market conditions.

Feeble financial figures, cheerful commentary

As noted, Nokia's Q4 results weren't great by the numbers. Net sales fell 21% year over year to $6.1 billion, hampered by limited orders from North American clients as they ride out the inflation crisis by tapping into overstocked equipment inventories. Adjusted earnings landed at $0.11 per diluted share, down from $0.16 per share in the year-ago report. Your average analyst expected earnings of roughly $0.15 per share on revenue near $7.1 billion.

On the upside, Nokia's operating margins widened in two of the three main business divisions. The mobile networks margin increased from 6.8% to 11.5%, while cloud and network services reported a 22.8% margin, up from 13.9% one year earlier. Segment-level sales were down across the board, but networks still saw operating profits rise by 45%, and services tallied 56% higher profit results. The cost-cutting program Nokia instituted last year is making a difference here.

Furthermore, Nokia's management reported "a significant improvement in order intake in the fourth quarter, particularly in Network Infrastructure." In other words, the lean years of American inflation worries seem to be ending, at least from this Finnish perspective.

It's time to finish stalled 5G network installations

It's kind of rare to see an earnings report fall a country mile short of analyst expectations, sparking a price jump in the process. In this case, Nokia's bears and critics are backing down as the company seems headed for more stable results in 2024 and beyond.

There are still some hurdles to negotiate, including difficulties exporting European communications infrastructure into China. But if U.S. customers get back to 5G network upgrades in 2024, as Nokia's C-suite comments suggest, the wireless infrastructure sector should see robust growth over the next couple of years. That's great news for longtime Nokia shareholders like yours truly.
