Domino's Pizza Inc. reported a mixed earnings performance, leading to a decline in its stock price. Despite beating earnings expectations, the company's guidance has raised concerns among investors. CEO Russ Weiner acknowledged the intense competition in the market, referring to the current environment as the 'pizza wars.' The company noted a decrease in business from lower-income consumers in August, attributing this to competitive promotions from rivals. However, Domino's dismissed the notion that promotions for frozen pizzas at grocery stores significantly impacted its sales. The company is also planning to expand its presence on food aggregators beyond Uber Eats. As of now, Domino's operates 21,000 restaurants globally.
