Southwest Airlines reported a fourth-quarter adjusted earnings per share (EPS) of $0.56, surpassing analysts' expectations of $0.44. However, the airline's total operating revenue of $6.93 billion fell short of the projected $6.96 billion. Following the mixed results, Southwest's shares declined by 4%. The airline's CEO, Bob Jordan, expressed satisfaction with the company's performance during the holiday season and highlighted a $500 million cost reduction target, which they aim to accelerate to 2025. Additionally, Southwest anticipates receiving 38 Boeing 737 MAX 8 aircraft deliveries in 2025. Despite the positive revenue boost from leisure travel, the company is facing above-normal unit cost inflation, particularly in wage rates and airport costs. This mixed performance has attracted scrutiny regarding the reporting of adjusted revenue alongside quarterly figures, raising potential regulatory concerns.
