Item 2.01.

Completion of Acquisition or Disposition of Assets.

On October 8, 2025, TransMontaigne Partners LLC (“TransMontaigne” or the “Company”) completed the sale of its terminal facility located on Fisher Island, Miami, Florida to HRP Fisher Island, LLC, a Delaware limited liability company. The Fisher Island terminal has active capacity of approximately 700,000 barrels for the storage of marine fuels. The purchase price was $180 million. Effective as of the closing, TransMontaigne leased the terminal facility from the buyer to allow TransMontaigne to continue its existing operations servicing its current customer agreements.

Proceeds from the sale of the Fisher Island terminal facility were used for the repayment of certain term debt obligations.

The purchase agreement relating to this transaction has not been filed as an exhibit to this Current Report on Form 8-K because the transaction is not material to the Company’s financial position or results of operations.
