Delta Air Lines Inc. (NYSE:DAL)

The financial performance from 2017 to 2021 is characterized by a period of steady growth, followed by a severe operational contraction in 2020, and a subsequent partial recovery in 2021.

EBITDA Performance Trends

Earnings before interest, tax, depreciation and amortization exhibited a generally positive trajectory between 2017 and 2019, reaching a peak of 9,080 million US dollars. This trend was abruptly reversed in 2020, with EBITDA falling to a deficit of 12,346 million US dollars. By 2021, a return to positive territory was observed, with EBITDA recovering to 3,675 million US dollars, although this figure remained significantly below the pre-2020 baseline.

Profitability and Net Income Correlation

Net income and earnings before tax mirrored the fluctuations seen in EBITDA. A consistent increase in net income was noted from 2017 to 2019, rising from 3,577 million US dollars to 4,767 million US dollars. The 2020 fiscal year experienced a profound collapse, with net income dropping to negative 12,385 million US dollars, representing a volatility swing of over 17 billion US dollars from the previous year's peak.

Operating Expense Analysis

The variance between EBIT and EBITDA indicates that depreciation and amortization remained a substantial and relatively stable cost component across the five-year period. Even during the severe operational downturn of 2020, the difference between these two metrics suggests that non-cash charges continued to impact the earnings profile, contributing to the depth of the losses reported in EBIT.

Recovery Phase Analysis

The 2021 data signifies a pivot toward recovery. While net income returned to a positive state at 280 million US dollars, the gap between EBITDA and net income suggests that while operational cash flow improved significantly, the full restoration of pre-crisis profitability levels had not yet been realized.

Between 2017 and 2019, the enterprise value and EBITDA exhibited relative stability, resulting in a consistent valuation multiple. The EV/EBITDA ratio during this period fluctuated within a narrow range between 5.08 and 5.48, suggesting a steady relationship between the total enterprise value and operational cash flow generation.

Enterprise Value Trends

The enterprise value remained remarkably resilient over the five-year period, fluctuating between a low of US$ 42,684 million and a peak of US$ 46,127 million. This suggests that the market's valuation of the overall business remained consistent regardless of the fluctuations in annual earnings.

EBITDA Volatility

Operational earnings experienced a severe contraction in 2020, shifting from US$ 9,080 million in 2019 to a loss of US$ 12,346 million. A partial recovery was observed in 2021, with EBITDA returning to a positive US$ 3,675 million, although this figure remained significantly lower than pre-2020 levels.

EV/EBITDA Multiple Expansion

The EV/EBITDA ratio expanded significantly to 11.62 by the end of 2021. This sharp increase was driven by the fact that the enterprise value returned to its historical baseline while EBITDA recovered only to approximately 40% of its 2019 peak. Consequently, the multiple more than doubled compared to the 2017-2019 average.
