−Removed: This ratio is an estimate of the equivalent energy content of the products and may not reflect their relative economic value.
−Removed: (3) Average prices reflect the before and after effects of our settled commodity derivatives.
−Removed: Our calculation of such after effects includes gains (losses) on settlements of commodity derivatives, which do not qualify for hedge accounting because we do not designate or document them as hedges for accounting purposes.
−Removed: (4) The average realized price for the nine months ended September 30, 2024 and 2025 includes $2 million and $1 million, respectively, of proceeds related to a take-or-pay contract.
−Removed: Excluding the effect of these proceeds, the average realized price for ethane before and after the effects of derivatives for the nine months ended September 30, 2024 and 2025 would have been $8.48 per Bbl and $11.66 per Bbl, respectively.

+Added: volumes accounted for an approximate $22 million increase in year-over-year NGLs revenues (calculated as the change in year-to-year volumes times the prior year average price).
+Added: Revenues from sales of oil decreased from $50 million for the three months ended March 31, 2025 to $47 million for the three months ended March 31, 2026, a decrease of $3 million, or 7%, primarily due to lower oil prices and production volumes, partially offset by $3 million of oil revenue attributable to the HG Acquisition properties.
Lower oil prices, excluding the effects of derivative settlements, accounted for an approximate $2 million decrease in year-over-year oil revenues (calculated as the change in the year-to-year average price times current year production volumes).
−Removed: Commodity derivative fair value gains.
−Removed: Our commodity derivatives included fixed price swaps, collars, basis swaps, call options and embedded put options.

+Added: For the three months ended March 31, 2025, commodity derivative fair value losses included $11 million of net cash payments for settled derivative losses.
+Added: For the three months ended March 31, 2026, commodity derivative fair value gains included $165 million of net cash payments for settled derivative losses.
Commodity derivative fair value gains or losses vary based on future commodity prices and have no cash flow impact until the derivative contracts are settled or monetized prior to settlement.
