Intense Competition: The fast-food industry is highly competitive, with numerous established and emerging players vying for market share, which could pressure Wendy's sales and profitability.

Food Safety Incidents: Any widespread foodborne illness or contamination event linked to Wendy's products could severely damage its brand reputation, lead to lawsuits, and result in significant financial losses.

Shifting Consumer Tastes: Evolving consumer preferences towards healthier options, plant-based diets, or different dining experiences could reduce demand for Wendy's traditional menu items if the company doesn't adapt effectively.
