Fair Value Disclosures [Abstract]  
FINANCIAL INSTRUMENTS
11. FINANCIAL INSTRUMENTS
Concentrations of Credit Risk. Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, restricted cash, and accounts receivable. The Company maintains its cash and cash equivalents and restricted cash in bank deposit accounts that frequently exceed federally insured limits. The Company has not experienced any losses in such accounts and does not believe it is exposed to any significant risk.
Accounts receivable primarily comprise amounts due for the gathering, compression, treating, and processing services the Company provides to its customers and also the sale of natural gas liquids resulting from its processing services. This industry concentration has the potential to impact its overall exposure to credit risk, either positively or negatively, in that the Company’s customers may be similarly affected by changes in economic, industry or other conditions. The Company monitors the creditworthiness of its counterparties and can require letters of credit or other forms of credit assurance for receivables from counterparties that are judged to have substandard credit unless the credit risk can otherwise be mitigated.
Fair Value. The carrying amount of cash and cash equivalents, restricted cash, accounts receivable and trade accounts payable reported on the consolidated balance sheet approximates fair value due to their short-term maturities.
A summary of the estimated fair value of the Company’s debt financial instruments follows.

(1) Excludes applicable unamortized debt issuance costs and debt discounts.
The carrying values on the balance sheets of both the Amended and Restated ABL Facility and Permian Transmission Term Loan represents their fair values due to their floating interest rates. The fair value for the 2029 Secured Notes is based on an average of nonbinding broker quotes as of December 31, 2025 and 2024. The use of different market assumptions or valuation methodologies may have a material effect on the estimated fair value.
Deferred Earn-Outs. The estimated fair value of the Company’s deferred earn-outs are remeasured each reporting period and estimated using discounted cash flow techniques with appropriate discount rates. Given the unobservable nature of the inputs, the fair value measurement of the deferred earn-out is deemed to use Level 3 inputs.
Tall Oak earn-out: In connection with the Tall Oak Acquisition, the Company incurred a deferred earn-out liability. As of December 31, 2025, the estimated fair value of the deferred earn-out liability recorded on the Company’s consolidated balance sheet was $21.5 million which is reflected within other current liabilities. The earn-out becomes payable to Tall Oak Parent subject to Tall Oak and its customers meeting certain development requirements.
Interest Rate Swaps. In connection with the Permian Transmission Term Loan, formerly the Permian Transmission Credit Facilities, SMLP entered into amortizing interest rate swap agreements. As of December 31, 2025 and 2024, the outstanding notional amount of interest rate swaps was $101.5 million and $116.4 million, respectively. These interest rate swaps manage exposure to variability in expected cash flows attributable to interest rate risk. Interest rate swaps convert a portion of the Company’s variable rate debt to fixed rate debt. The Company chooses counterparties for its derivative instruments that it believes are creditworthy at the time the transactions are entered into, and the Company actively monitors the creditworthiness where applicable. However, there can be no assurance that a counterparty will be able to meet its obligations to the Company. The Company presents its derivative positions on a gross basis and does not net the asset and liability positions.
As of December 31, 2025 and 2024, the Company’s interest rate swap agreements had a fair value of $6.6 million and $11.0 million, respectively, and are recorded within other noncurrent assets within the consolidated balance sheets. The derivative instruments’ fair value are determined using level 2 inputs from the fair value hierarchy.
