Interest Rate Risk Long-Term Debt A portion of our long-term debt is variable-rate debt. Changes in interest rates impact the interest payments of our variable-rate debt but generally do not impact the fair value of the liability. Conversely, changes in interest rates impact the fair value of our fixed-rate debt but do not impact its cash flows. The ABL Facility is variable-rate debt with interest rates that are generally indexed to the prime rate or a secured overnight financing rate (“SOFR”) plus an applicable margin. At June 30, 2026, $177.0 million was outstanding under the ABL Facility at a weighted average interest rate of 5.84%. A change in interest rates of 0.125% would result in an increase or decrease of our annual interest expense of $0.2 million, based on borrowings outstanding at June 30, 2026. The 2026 Term Loan B is variable-rate debt with interest rates that are generally indexed to the SOFR plus an applicable margin. At June 30, 2026, $947.6 million was outstanding under the 2026 Term Loan B with an interest rate of SOFR of 3.63% plus a margin of 3.50%. A change in interest rates of 0.125% would result in an increase or decrease of our annual interest expense of $1.2 million, based on borrowings outstanding at June 30, 2026. Interest Rate Swaps In March and April 2024, we entered into two $200.0 million interest rate swaps to reduce the variability of cash outflows associated with our floating-rate, SOFR-based instruments. One of the interest rate swaps expired in April 2026. An increase of 10% in the value of the underlying interest rate swap would result in a net change in the fair value of our interest rate swap of less than $0.1 million at June 30, 2026. Preferred Unit Distributions The current distribution rate for the Class B Preferred Units is the three-month CME Term SOFR interest rate plus a tenor spread adjustment of 0.26161% plus a spread of 7.213% (see Note 8 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion). A change in interest rates of 0.125% would result in an increase or decrease of our quarterly Class B Preferred Unit distribution of $0.1 million, based on the Class B Preferred Units outstanding at June 30, 2026. The current distribution rate for the Class C Preferred Units is the three-month CME Term SOFR interest rate plus a spread of 7.384% (see Note 8 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion). A change in interest rates of 0.125% would result in an increase or decrease of our quarterly Class C Preferred Unit distribution of less than $0.1 million, based on the Class C Preferred Units outstanding at June 30, 2026. The current distribution rate for the Class D Preferred Units is the three-month CME Term SOFR interest rate plus a spread of 7.00% (see Note 8 to our unaudited condensed consolidated financial statements included in this Quarterly Report for a further discussion). A change in interest rates of 0.125% would result in an increase or decrease of our quarterly Class D Preferred Unit distribution of $0.1 million, based on the Class D Preferred Units outstanding at June 30, 2026. Commodity Price Risk Our operations are subject to certain business risks, including commodity price risk. Commodity price risk is the risk that the market value of crude oil or natural gas liquids will change, either favorably or unfavorably, in response to changing market conditions. Procedures and limits for managing commodity price risks are specified in our market risk policy. Open commodity positions and market price changes are monitored daily and are reported to senior management and to marketing operations personnel. The crude oil and natural gas liquids industries are “margin-based” and “cost-plus” businesses in which our realized margins depend on the differential of sales prices over our supply costs. We have no control over market conditions. As a result, our profitability may be impacted by sudden and significant changes in the price of crude oil and natural gas liquids. We engage in various types of forward contracts and financial derivative transactions to reduce the effect of price volatility on our product costs, to protect the value of our inventory positions, and to help ensure the availability of product 49 Table of Contents during periods of short supply. We attempt to balance our contractual portfolio by purchasing volumes when we have a matching purchase commitment from our commercial, retail and industrial customers. We may experience net unbalanced positions from time to time. In addition to our ongoing policy to maintain a balanced position, for accounting purposes we are required, on an ongoing basis, to track and report the market value of our derivative portfolio. Although we use financial derivative instruments to reduce the market price risk associated with forecasted transactions, we do not account for financial derivative transactions as hedges. All changes in the fair value of our physical contracts that do not qualify as normal purchases and normal sales and settlements (whether cash transactions or non-cash mark-to-market adjustments) are reported within cost of sales-product (for purchase contracts) in our unaudited condensed consolidated statements of operations, regardless of whether the contract is physically or financially settled, and within cash flows from operations in our unaudited condensed consolidated statements of cash flows. The following table summarizes the hypothetical impact on the June 30, 2026 fair value of our commodity derivatives of an increase of 10% in the value of the underlying commodity. Increase (Decrease) To Fair Value (in thousands) Crude oil (Water Solutions segment) $ (499) Crude oil (Crude Oil Logistics segment) $ 246 Propane (Liquids Logistics segment) $ 634 Butane (Liquids Logistics segment) $ 15,512 Other (Liquids Logistics segment) $ 236 Changes in commodity prices may also impact the volumes that we are able to transport, dispose, store and market, which also impact our cash flows. Credit Risk Our operations are also subject to credit risk, which is the risk of loss from nonperformance by suppliers, customers or financial counterparties to a contract. Procedures and limits for managing credit risk are specified in our credit policy. Credit risk is monitored daily and we believe we minimize exposure through the following: •requiring certain customers to prepay or place deposits for our products and services; •requiring certain customers to post letters of credit or other forms of surety; •monitoring individual customer receivables relative to previously-approved credit limits; •requiring certain customers to take delivery of their contracted volume ratably rather than allow them to take delivery at their discretion; •entering into master netting agreements that allow for offsetting counterparty receivable and payable balances for certain transactions; •reviewing the receivable aging regularly to identify issues or trends that may develop; and •requiring marketing personnel to manage their customers’ receivable position and suspend sales to customers that have not timely paid outstanding invoices. At June 30, 2026, our primary counterparties were retailers, resellers, energy marketers, producers, refiners, and dealers. Fair Value We determine the fair value of our exchange traded derivative financial instruments utilizing publicly available prices, and for non-exchange traded derivative financial instruments, we utilize pricing models for similar instruments including publicly available prices and forward curves generated from a compilation of data gathered from third-parties. 50 Table of Contents
