Ecopetrol S.A. (EC) Income Statement

The sharp rebound in 2026Q2 appears driven by commodity price recovery, yet the preceding four quarters showed consistent YoY declines, indicating a cyclical trough. The -16.4% drop in 2025Q4 and -18.2% in 2025Q4 highlight the company's sensitivity to oil prices. Investors should monitor whether this uptick is sustainable or a temporary reprieve amid global supply dynamics.

The margin expansion in 2026Q2 suggests that Ecopetrol benefits from lower input costs or higher realized prices, but the sustainability is questionable given the prior quarters' compressed margins. The 22.27% operating margin over the period is below peers like Petrobras (31.4%), implying structural cost disadvantages. The company's integrated model, including midstream and refining, may provide a buffer, but the cyclicality of upstream margins remains a key risk.

The disproportionate rise in operating income relative to revenue indicates that fixed costs are being covered more efficiently as volumes or prices recover. However, this leverage cuts both ways: in 2025Q4, a -18.2% revenue decline led to a -62.2% drop in EPS, showing the downside risk. SG&A remained relatively stable, suggesting management is controlling overhead, but the high fixed-cost base of pipelines and refineries amplifies earnings volatility.

The reduction in COGS relative to revenue suggests better operational efficiency or lower input costs, but the increase in SG&A in 2026Q2 warrants attention. The company's high fixed costs in mature fields and pipeline maintenance remain a drag, and the -16.4% revenue decline in 2025Q4 likely pressured margins. Management's ability to control costs during downturns will be critical, especially with potential regulatory changes affecting royalty deductions.

The trough in 2025Q4 appears driven by a combination of low oil prices and possibly higher costs, leading to a net margin of just 5.2%. The subsequent recovery in 2026Q2 suggests a cyclical upturn, but the sustainability depends on oil price stability and production volumes. This inflection highlights the company's vulnerability to commodity cycles, despite its diversified infrastructure assets.
