(1)The carrying value of long-term debt is reduced by debt issuance cost, net of accumulated amortization, of $34.9 million and $27.8 million as of December 31, 2022 and 2021, respectively. The respective fair values do not factor in debt issuance costs.

(2)Consideration for the Amarillo Rattler Acquisition included a $10.0 million installment payable, which was paid on April 30, 2022, and a contingent component capped at $15.0 million and payable, if at all, between 2024 and 2026 based on Diamondback E&P LLC’s drilling activity above historical levels. Estimated fair values were calculated using a discounted cash flow analysis that utilized Level 3 inputs.

(3)Consideration for the Central Oklahoma Acquisition included an earnout payable, if at all, between 2024 and 2027 based on fee revenue earned on certain contractually specified volumes for the annual periods beginning January 1, 2023 through December 31, 2026. As of December 31, 2022, we recorded a $1.3 million liability related to the earnout.
