Oil and gas lease operating expenses show a decreasing trend as a percentage of net sales from early 2020 into mid-2022, likely reflecting improved operational efficiency, yet the ratio increases again by the end of 2023 through 2025, signifying rising operating costs relative to net sales.

Purchased commodities costs reduce significantly from early 2024 onward, possibly indicating changes in sourcing strategies or commodity price variations.

Selling, general, and administrative expenses fluctuate moderately but remain within a narrow range, demonstrating consistent overhead cost management.

Other operating and non-operating expenses show erratic behavior, including a notable drop to nearly negligible levels in early 2023 before rising again, signaling irregular non-recurring charges or cost adjustments.

Taxes other than on income remain relatively stable as a percentage of net sales, with minor fluctuations suggestive of consistent tax obligations outside income taxes.

However, variability emerges again later, with significant declines in early 2025.

Net income attributable to common stockholders follows a similar trajectory, showing large losses in 2020, gradual recovery through 2021 and 2022, peaking with strong positive net incomes in 2022 and 2023, before diminishing toward negative territory in early 2025.

Income tax expense percentages vary widely, reflecting volatile pre-tax income, with periodic benefits and expenses impacting overall profitability.
