The common-size income statement reveals a period of significant volatility in operating profitability, characterized by a substantial expansion of margins in 2022 followed by a period of stabilization and periodic fluctuations through 2026.
- Revenue and Operating Performance
- Operating income as a percentage of sales demonstrated a marked increase, peaking at 24.21% in September 2022. While margins retracted in the subsequent year, they generally remained above the 2021 baseline, ending the observed period at 19.37% in September 2026. This trajectory suggests a structural shift toward higher operational margins compared to the start of the period.
- Primary Cost Drivers
- Crude oil and product purchases represent the most significant expenditure, consistently consuming between 54% and 62% of revenue. Production and manufacturing expenses remained relatively stable, typically ranging between 9% and 15%, though a relative dip was observed during the high-margin window of mid-2022.
- Operating Expenses and Depreciation
- Selling, general, and administrative expenses showed a general downward trend relative to revenue, decreasing from 4.22% in March 2021 to a low of 2.17% in March 2026. Depreciation and depletion costs were more volatile, fluctuating between a low of 4.00% in June 2022 and peaks exceeding 10% in March 2022 and September 2025, reflecting varying cycles of asset impairment and investment.
- Fiscal Obligations and Net Profitability
- Other taxes and duties experienced a consistent long-term decline, falling from 11.57% in early 2021 to between 4% and 7% by 2026. Net income attributable to the company mirrored the volatility of operating income, reaching a peak of 18.46% in September 2022. Despite a significant contraction to 5.03% in March 2026, profitability recovered to 13.95% by September 2026.
