Did The New All-Day Breakfast Help McDonald's Post Best Q4 In Four Years?

McDonald's Corporation (NYSE: MCD)'s latest announcement to move to all-day breakfast helped boost the company's best fourth-quarter profit and revenue results in the United States in nearly four years.

Shares have risen 1.64 percent to $120.34 in Monday's trading session at the time of this publication.

Biggest Change In 7 Years

The all-day breakfast launched in October, and has been McDonald's largest transition since its 2009 announcement of nationally available McCafe beverages.

CEO Stephen Easterbrook's turnaround began to take effect during the third quarter. At that time, McDonald's U.S. division had posted its first quarterly increase in same-store sales in two years.

McDonald's fourth-quarter results were "a testament to the swift changes we made and the early impact of our turnaround efforts," Easterbrook stated.

"McDonald's U.S. business begins 2016 as a customer-led organization focused on delivering outstanding customer service through comprehensive simplification efforts, core menu enhancements and a compelling everyday national value platform. Generating sustained, positive guest traffic remains a top priority for the segment," said McDonald's, according to the Wall Street Journal.
