McDonald’s so far unfazed by latest entrant in breakfast war by John Kell @FortuneMagazine May 8, 2014, 5:05 PM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons FORTUNE — Waffle tacos and breakfast burritos haven’t yet become a formidable challenger to McDonald’s Corp.’s MCD most profitable meal of the day: breakfast. The fast-food chain said Thursday its global same-store sales climbed 1.2% last month, boosted by strong results in China. Sales were flat in the U.S., although the figure came in line with analysts’ estimates. It was the first full month since Yum! Brands Inc.’s YUM Taco Bell chain debuted a breakfast menu with steak and egg burritos, waffle tacos and flatbread melts, among other items. After Taco Bell entered the market in late March, McDonald’s responded by announcing a two-week promotion that would give breakfast customers a free cup of McCafe coffee at its participating locations. A number of restaurant chains have made a push to offer more breakfast options, competition that could potentially hurt McDonald’s.

Hottovy. “It’s very easy to come up with a breakfast platform, but very difficult to sustain it. I don’t see Taco Bell challenging McDonald’s dominance in the category any time soon.” Breakfast is an important part of the day for restaurant chains. Over 12.5 billion breakfast visits were made in the U.S. last year, according to research firm NPD Group. NPD said traffic at that time of the day rose 3% in 2013, while restaurant visits for lunch and dinner declined. Sterne Agee Senior Research Analyst Lynne Collier said that while Taco Bell could eventually eat into McDonald’s business, it will take some time for the Yum! division to build a notable market share in the breakfast business.

Internationally, McDonald’s same-store sales rose 0.3% in Europe and climbed 2.9% in the Asia/Pacific, Middle East and Africa region. Same-store sales track sales at all McDonald’s restaurants that have been in operation at least 13 months.
