How McDonald's Crushed It in 2017

McDonald's (NYSE: MCD) is reaping the benefits of its three years of turnaround efforts. The fast-food chain, which boasts more than 36,000 global locations, saw its stock rise about 40% in 2017 as it experienced increased customer traffic after some updates to its menu and restaurants.

On Jan. 30, McDonald's released its fourth-quarter and full-year results. Customer traffic grew by 1.9% year over year for the full 2017 year, which marked the first increase on that metric in five years.

To figure out why McDonald's stock shot up that much in 2017, we need to take a closer look at the company's overall turnaround plans that seem to be moving faster than expected.

Same-store sales got a lot juicier

McDonald's same-store sales figures from 2017 were the proof it needed to show investors that its turnaround efforts are working.

The first quarter brought a 4% increase in global comparable sales for McDonald's. In an April 25 letter to investors, the company's CEO Steve Easterbrook said the team was working to keep existing customers and win back lost customers by focusing on making the in-store experience more efficient and enjoyable with things like menu and technology updates.

"Our efforts to build a better McDonald's are yielding meaningful results with continued positive momentum and a strong start to 2017 that includes positive comparable sales across all segments, higher global guest counts and enhanced profitability," Easterbrook said at the time.

For the second quarter, McDonald's reported a global same-store sales increase of 6.6%. This was significant because it was the company's strongest global comparable sales results in over five years.

Although growth slowed a bit compared to the second quarter, the second half of 2017 was also encouraging -- global same-store sales increased 6% in the third quarter and 5.5% in the fourth quarter -- as the company marked its 10th consecutive quarter of global same-stores growth.

In its full-year report, McDonald's said 2017 ended up being its best full-year global comparable-store sales performance in six years with an increase of 5.3%. "Our results demonstrate we successfully completed the transition from turnaround to growth," Easterbrook said on the fourth-quarter earnings call.

Updates to stores helped increase foot traffic

The company spent 2017 working to improve the in-store experience for customers. That meant serving food that was fresher and hotter, as well as offering friendlier service, Easterbrook said.
