United Airlines Holdings Inc. (NASDAQ:UAL)

The common-size income statement reveals a significant shift in financial performance over the five-year period. Initially experiencing substantial losses, the company demonstrates a clear trajectory towards profitability, although some fluctuations are observed. Revenue composition evolves, and expense management appears to improve, contributing to the overall positive trend.

Revenue Composition

Passenger revenue consistently represents the dominant portion of operating revenue, ranging from approximately 82% to 91%. While initially decreasing from 81.99% in 2021 to 89.05% in 2022, it stabilizes around 90% for the subsequent years. Cargo revenue experiences a marked decline, decreasing from 9.54% to 2.78% and remaining relatively low. Other operating revenue exhibits a modest increase over the period, rising from 8.48% to 6.52%. These shifts suggest a growing reliance on passenger travel and a diminishing contribution from cargo services.

Expense Management

Salaries and related costs represent a substantial portion of operating revenue, initially at -38.83% in 2021, decreasing to -25.51% in 2022, then fluctuating between -27.53% and -29.87% in subsequent years. Aircraft fuel costs demonstrate significant volatility, decreasing from -23.36% in 2021 to -29.17% in 2022, then decreasing to -19.29% in 2025. Landing fees and other rent also decrease over time, though less dramatically. Depreciation and amortization consistently represents a significant expense, decreasing from -10.09% to -4.98%. The combined effect of these expense trends contributes to improved operating performance.

Operating Performance

Operating income (loss) transitions from a substantial loss of -4.15% in 2021 to a positive income of 5.20% in 2022, continuing to improve to 8.93% in 2024 before slightly decreasing to 7.98% in 2025. This improvement is largely attributable to the changes in revenue composition and expense management. The impact of the CARES Act grant is notable in 2021, contributing 16.32% to operating revenue, but this benefit disappears in subsequent years. Special (charges) credits also contribute significantly in 2021, but become negative in later years.

Non-Operating Items & Net Income

Interest expense, net of interest capitalized, consistently represents a negative percentage of operating revenue, but decreases over time, indicating improved debt management. Interest income shows a positive trend, increasing from 0.15% to 1.03%. Net income (loss) mirrors the trend in operating income, moving from a loss of -7.97% in 2021 to a profit of 5.68% in 2025. Income tax expense fluctuates, initially positive, then negative, and finally stabilizing around -1.6%. The overall trend indicates a substantial improvement in profitability.

In summary, the company demonstrates a strong recovery and improvement in financial performance over the analyzed period. While passenger revenue remains the primary driver, effective expense management and favorable trends in non-operating items contribute to a sustained increase in net income.
