Think Delta Air Lines Is Expensive? This Chart Might Change Your Mind.

Despite concerns about Delta Air Lines' $16.9 billion adjusted net debt and cyclical revenue, the airline's profitability, as measured by return on invested capital (ROIC), has consistently exceeded its weighted average cost of capital (WACC), unlike many budget airlines. Delta, along with United, has shown resilience due to factors like strong loyalty programs and co-branded credit cards, allowing them to better navigate rising costs and economic downturns compared to budget carriers, suggesting a more favorable risk-reward profile for Delta's stock.

Analysis

Delta Air Lines (DAL), despite an adjusted net debt of $16.9 billion and the airline industry's traditional cyclicality, presents a potentially undervalued investment case, trading at a price-to-earnings ratio of just over 8. The company, along with United Airlines, has demonstrated a significant divergence in performance by consistently achieving a return on invested capital (ROIC) exceeding the estimated industry weighted average cost of capital (WACC) of 8-9%. This contrasts sharply with American Airlines and budget carriers, the latter of which have seen their ROIC decline post-pandemic while major network carriers maintained pre-pandemic levels. This outperformance is attributed to several factors: rising labor, airport, and supply chain costs disproportionately impacting budget airlines' low-margin models; the greater ease for premium airlines to offer economy seats versus budget airlines upgrading to premium; and substantial revenue generation from loyalty programs and co-branded credit cards. These elements suggest Delta possesses increased resilience against economic downturns compared to budget competitors, leading to a potentially more favorable risk-reward profile than its current valuation might imply. However, it is noteworthy that The Motley Fool Stock Advisor did not include Delta in its recent list of top 10 stocks, despite the positive operational indicators.

Key Decisions for Investors

• Investors should assess Delta's valuation considering its sustained ROIC above WACC and its operational advantages, which may not be fully reflected in its current P/E ratio despite its debt.
• Monitor the widening performance gap and competitive pressures between network carriers like Delta and budget airlines, as this trend could offer relative stability for Delta, particularly in fluctuating economic conditions.
• Balance the article's positive outlook on Delta's fundamentals and resilience with third-party analyst perspectives, such as its current exclusion from The Motley Fool's top stock recommendations, when making investment decisions.
