KINDER MORGAN, INC.

The following tables summarize the key components of our consolidated earnings results.

Our consolidated revenues primarily consist of services and sales revenue. Our services revenues include fees for transportation and other midstream services that we perform. Fluctuations in our consolidated services revenue largely reflect changes in volumes and/or in the rates we charge. Our consolidated sales revenues include sales of natural gas (includes natural gas and RNG), products (includes NGL, crude oil, CO 2, and transmix), and other (includes RINs). Our consolidated sales revenue will fluctuate with commodity prices and volumes, and the costs of sales associated with purchases will usually have a commensurate and offsetting impact, except for the CO 2 segment, which produces, instead of purchases, the crude oil, CO 2, and RINs it sells. Additionally, fluctuations in revenues and costs of sales may be further impacted by gains or losses from derivative contracts that we use to manage our commodity price risk.

Below is a discussion of significant changes in our Consolidated Earnings Results for the comparable three-month periods ended March 31, 2026 and 2025:

Revenues

Revenues increased$587 million in 2026 compared to 2025. The increase was primarily due to (i) an increase in natural gas sales of $460 million due to higher commodity prices and volumes; and (ii) an increase in services revenues of $157 million resulting from higher volumes, primarily driven by increased demand for services and expansion projects placed into service, and higher rates partially offset by a decrease in product sales of $34 million driven primarily by lower commodity prices. The increase in sales revenues was partially offset by a corresponding increase in our costs of sales as described below under “Operating Costs, Expenses and Other—Costs of sales.”

Operating Costs, Expenses and Other

Costs of sales

Costs of sales increased $273 million in 2026 compared to 2025. The increase was primarily due to (i) an increase of $300 million of costs of sales for natural gas primarily due to higher volumes and commodity prices; and (ii) an increase of$20 million related to derivative contracts used to hedge commodity purchases. The increase was partially offset by a decrease of$69 million of costs of sales for products driven by lower commodity prices.

Other Income (Expense)

Interest, net

In the table above, we report our interest expense as “net,” meaning that we have subtracted interest income and capitalized interest from our total interest expense to arrive at one interest amount. Interest, net decreased $21 million in 2026 compared to 2025. The decrease was primarily due to lower interest rates associated with our fixed-to-variable interest rate swap agreements and lower average short-term debt balances partially offset by higher interest rates and average balances on our long-term debt.
