McDonald's Corp. (NYSE: MCD) shares suffered their largest single-day drop in more than a year Tuesday after a research firm warned that the fast food chain could deliver worse-than-expected results in its third fiscal quarter, Bloomberg reports.
The report sent shares of the company falling 3.6%, to $155.77 — the worst result since July 26, 2016.
Data tracker M Science said Tuesday that its sales forecast for the Golden Arches is weaker than that of Wall Street analysts.
The report found that the burger chain will likely miss on domestic revenue and same-store sales in the coming quarter.
Hurricane Harvey, which hit Texas last month, and Hurricane Irma, which is still making its way up the east coast, is expected to weigh heavily on August and September sales at restaurants. McDonald's, which has more than 2,000 locations in Texas and Florida, is not immune to these expected declines.
