Delta Air Lines (NYSE:DAL) is a major American airline, known for its extensive domestic and international flight network. It competes with other major airlines like American Airlines and United Airlines. On October 9, 2025, Delta reported an earnings per share (EPS) of $1.71, exceeding the estimated EPS of $1.52. However, its revenue of $15.2 billion fell short of the expected $15.96 billion.

Despite the revenue miss, Delta's stock price surged nearly 7% on the same day, as highlighted by the company's announcement of better-than-expected third-quarter results. The adjusted revenue of $15.2 billion for the September quarter marked a 4.1% increase from the previous year, surpassing analyst expectations of $15.08 billion. This growth reflects a strong recovery in the travel sector.

Delta's improved earnings performance, with an EPS of $1.71 compared to $1.50 in the same quarter last year, has bolstered investor confidence. The company has also raised its full-year earnings guidance, further enhancing its stock's appeal. This positive outlook is supported by a surge in travel demand, leading to record revenue and benefiting Delta and its industry peers.

Financially, Delta's valuation metrics indicate a strong position. With a price-to-earnings (P/E) ratio of approximately 6.18, the stock is considered undervalued relative to its earnings. The price-to-sales ratio of about 0.63 suggests investors are paying 63 cents for every dollar of sales, while the enterprise value to sales ratio of 0.82 reflects the company's total valuation relative to its sales.

Delta's financial health is further demonstrated by its earnings yield of about 16.19%, indicating a solid return on investment for shareholders. The debt-to-equity ratio of approximately 0.83 shows a balanced use of debt and equity in financing its assets. However, the current ratio of about 0.40 suggests a need for improvement in covering short-term liabilities with short-term assets.
