McDonald's earnings and revenue fall short of expectations as consumer demand weakens.

• McDonald's missed second-quarter earnings and revenue estimates.
• Since the fourth quarter of 2020, the company's same-store sales have been declining.
• McDonald's is relying on value meals to attract customers again as it faces a growing consumer resistance.

On Monday, the company reported quarterly earnings and revenue that fell short of analysts' expectations, as same-store sales decreased across all divisions.

Based on a survey of analysts by LSEG, the company's reported results differed from Wall Street's expectations.

• Earnings per share: $2.97 adjusted vs. $3.07 expected
• Revenue: $6.49 billion vs. $6.61 billion expected

McDonald's reported a decline in second-quarter net income, with earnings of $2.02 billion, or $2.80 per share, compared to $2.31 billion, or $3.15 per share, in the same period last year. However, when excluding charges related to the sale of its South Korean business and other items, McDonald's earned $2.97 per share.

In contrast to the previous year, the company's quarterly revenue of $6.49 billion remained unchanged.

McDonald's same-store sales decreased by 1%, falling short of StreetAccount's growth estimate of 0.4%. This marks the first time the company has experienced a decline in same-store sales since the fourth quarter of 2020.

In the U.S., McDonald's reported a 10.3% increase in same-store sales a year ago, but this quarter, its same-store sales decreased by 0.7%.

In the past 12 months, more consumers have reduced their restaurant spending, especially at fast-food chains, which they no longer consider a good value. McDonald's reported a decline in foot traffic to its U.S. restaurants during the quarter.

McDonald's is introducing a $5 meal deal in late June to attract customers, as executives had previously warned about the intensified competition in the consumer environment.

Last week, the company announced that it would prolong the value meal beyond the initial four-week timeframe and stated that it would attract customers back.

McDonald's is attempting to attract customers outside of the U.S. through its international operated markets division, which includes significant markets like France and Germany. Despite this, the same-store sales in these markets decreased by 1.1% in the quarter.

McDonald's is still grappling with the aftermath of boycotts in the Middle East and sales in China remain challenging, as reported by the company's international developmental licensed markets unit, which encompasses both China and Japan, and experienced a 1.3% decline in same-store sales.
