Domino's Pizza experienced a 3% stock price decline due to disappointing same-store sales figures. Both US and international comparable sales growth fell short of analyst expectations. This underperformance occurred even though Domino's earnings and revenue surpassed Bloomberg Consensus estimates. A key reason cited for this weakness is a shift in consumer preferences. Budget-conscious consumers are increasingly favoring chicken over pizza when dining out. This trend is amplified by the "proteinmaxxing" movement. Other pizza chains like Papa John's and Pizza Hut are also facing similar challenges. Data indicates that chicken-centric quick-service restaurants are reporting stronger sales. This suggests that protein-focused meals are gaining traction. The combination of affordability and the "proteinmaxxing" trend is likely influencing these shifting meal preferences.
