TransMontaigne Partners LLC and Subsidiaries

Notes to consolidated financial statements (unaudited)

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a) Nature of business

TransMontaigne Partners LLC (“we,” “us,” “our,” “the Company”) provides integrated terminaling, storage, transportation and related services for companies engaged in the trading, distribution and marketing of light refined petroleum products, heavy refined petroleum products, renewable products, crude oil, chemicals, fertilizers and other liquid products. We conduct our operations in the United States along the Gulf Coast, in the Midwest, in Houston and Brownsville, Texas, along the Mississippi and Ohio rivers, in the Southeast and along the West Coast. In addition, we sell refined and renewable products to major fuel producers and marketers in the Pacific Northwest at our terminal in Tacoma, Washington.

Terminal Facilities sale agreements. On January 22, 2025, the Company announced that it had entered into separate agreements for the sale of our terminal facilities on Fisher Island Miami, Florida and in Fairfax, Virginia. Proceeds from the terminal sales will be used for repayment of certain term debt obligations.

The Fisher Island terminal has active capacity of approximately 700,000 barrels for the storage of marine fuels. The purchase price is approximately $180 million. The closing of the sale is expected to occur in the third quarter of 2025, subject to customary closing conditions. Following the closing, we will lease the terminal from the buyer to allow us to continue servicing our current customer agreements through approximately May 2027. The Fisher Island land has been recorded as assets held for sale (see Note 5 of Notes to consolidated financial statements).

The Fairfax terminal has active capacity of approximately 500,000 barrels for the storage of gasoline, diesel, ethanol, and fuel additives. The purchase price is approximately $30.8 million. The closing of the sale is expected to occur on or about June 30, 2026, subject to certain rights for the Company to extend the closing date. The closing is subject to customary closing conditions.

(b) Basis of presentation and use of estimates

Our accounting and financial reporting policies conform to accounting principles generally accepted in the United States of America (“GAAP”). The accompanying consolidated financial statements include the accounts of TransMontaigne Partners LLC and its controlled subsidiaries. Investments where we do not have the ability to exercise control, but do have the ability to exercise significant influence, are accounted for using the equity method of accounting. All intercompany accounts and transactions have been eliminated in the preparation of the accompanying consolidated financial statements. The accompanying consolidated financial statements include all adjustments (consisting of normal and recurring accruals) considered necessary to present fairly our financial position as of March 31, 2025 and December 31, 2024 and our results of operations for the three months ended March 31, 2025 and 2024.

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. In management’s opinion, the estimate of useful lives of our plant and equipment are subjective in nature, require the exercise of judgment and involve complex analyses. Changes in these estimates and assumptions will occur as a result of the passage of time and the occurrence of future events. Actual results could differ from these estimates.

(c) Accounting for terminal operations

We generate revenue from terminaling services fees, management fees and product sales. Under Topic 606, Revenue from Contracts with Customers (“ASC 606”) and Topic 842, Leases and the series of related Accounting Standards Updates that followed (collectively referred to as “ASC 842”), we recognize revenue over time or at a point in time, depending on the nature of the performance obligations contained in the respective contract with our customer. The

9

TransMontaigne Partners LLC and Subsidiaries

Notes to consolidated financial statements (unaudited) (continued)

contract transaction price is allocated to each performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The following is an overview of our significant revenue streams, including a description of the respective performance obligations and related method of revenue recognition.

Terminaling services fees. Our terminaling services agreements are structured as either throughput agreements or storage agreements. Our throughput agreements contain provisions that require our customers to make minimum payments, which are based on contractually established minimum volumes of throughput of our customer’s product at our facilities, over a stipulated period of time. Due to this minimum payment arrangement, we recognize a fixed amount of revenue from the customer over a certain period of time, even if the customer throughputs less than the minimum volume of product during that period. In addition, if a customer throughputs a volume of product exceeding the minimum volume, we would recognize additional revenue on this incremental volume. Our storage agreements require our customers to make minimum payments based on the volume of storage capacity available to the customer under the agreement, which results in a fixed amount of recognized revenue. We refer to the fixed amount of revenue recognized pursuant to our terminaling services agreements as being “firm commitments.”

Our terminaling services agreements include revenue recognized in accordance with ASC 606 and ASC 842. At the time of contract inception, we evaluate each contract to determine whether the contract contains a lease. Significant assumptions used in this process include the determination of whether substantive substitution rights exist based on the terms of the contract and available capacity at the terminal at the time of contract inception. Our terminaling services agreements do not allow our customers to purchase the underlying asset and vary in terms and conditions with respect to extension or termination options. If a contract is accounted for as a lease under ASC 842, we recognize the minimum payments as lease revenue and revenue recognized in excess of firm commitments as a variable payment of the lease. All other components of the contracts accounted for as a lease are treated as non-lease components (ancillary revenue) and are accounted for in accordance with ASC 606. The majority of our firm commitments under our terminaling services agreements are accounted for as lease revenue in accordance with ASC 842. The remaining firm commitments under our terminaling services agreements not accounted for as lease revenue are accounted for in accordance with ASC 606, where the minimum payment arrangement in each contract is considered a single performance obligation that is primarily satisfied over time through the contract term.

Revenue recognized in excess of firm commitments and revenue recognized based solely on the volume of product distributed or injected are referred to as ancillary. The ancillary revenue associated with terminaling services include volumes of product throughput that exceed the contractually established minimum volumes, injection fees based on the volume of product injected with additive compounds, heating and mixing of stored products, product transfer, railcar handling, butane blending, proceeds from the sale of product gains, wharfage and vapor recovery. The revenue generated by these services is required to be estimated under ASC 606 for any uncertainty that is not resolved in the period of the service. We account for the majority of ancillary revenue at individual points in time when the services are delivered to the customer. The majority of our ancillary revenue is recognized in accordance with ASC 606 (see Note 15 of Notes to consolidated financial statements).

Management fees. We manage and operate certain tank capacity at our Port Everglades South terminal for a major oil company and receive a reimbursement of its proportionate share of operating and maintenance costs. We manage and operate the Frontera Brownsville LLC (“Frontera”) joint venture and receive a management fee based on our costs incurred. We lease land under operating leases as the lessor or sublessor with third parties and affiliates. We manage and operate rail sites at certain Southeast terminals on behalf of a major oil company and receive reimbursement for operating and maintenance costs. We manage and operate the SeaPort Midstream Partners, LLC (“SeaPort Midstream”) joint venture and receive a management fee based on our costs incurred. We also manage additional terminal facilities that are owned by affiliates of ArcLight, including Lucknow-Highspire Terminals, LLC, which operates terminals throughout Pennsylvania encompassing approximately 9.9 million barrels of storage capacity and we receive a management fee based on our costs incurred. Our administration of payroll for Lucknow-Highspire Terminals, LLC ended on December 31, 2024.

10

TransMontaigne Partners LLC and Subsidiaries

Notes to consolidated financial statements (unaudited) (continued)

Management fee revenue is recognized at individual points in time as the services are performed or as the costs are incurred and is primarily accounted for in accordance with ASC 606. Management fees related to lease revenue are accounted for in accordance with ASC 842.

Product sales. Our product sales revenue refers to the sale of refined and renewable products at our terminal in Tacoma, Washington. Product sales revenue pricing is contractually specified, and we have determined that each transaction represents a separate performance obligation. Product sales revenue is recognized at a point in time when our customers take control and legal title of the commodities purchased. Product sales revenue is recorded gross of cost of product sales, which includes product purchases and transportation costs, as we are responsible for fulfilling the promise in the sales contract and maintain inventory risk. Product sales revenue is accounted for in accordance with ASC 606.

(d) Cash and cash equivalents

We consider all short-term investments with a remaining maturity of three months or less at the date of purchase to be cash equivalents.

(e) Inventory

Inventory represents refined and renewable products held for resale and are recorded at the lower of cost or net realizable value. Cost is determined by using the average cost method. At March 31, 2025 and December 31, 2024, our inventory was approximately $12.4 million and $9.9 million, respectively. At March 31, 2025 and December 31, 2024, our refined products inventory was approximately $8.8 million and $3.6 million, respectively. At March 31, 2025 and December 31, 2024, our renewable products inventory was approximately $3.6 million and $6.3 million, respectively. We did not recognize any adjustments to the lower of cost or net realizable value during the three months ended March 31, 2025 and 2024.

In 2021, the Washington legislature passed a low carbon fuel standard (the “Clean Fuel Standard” or “CFS”) that limits carbon in transportation fuels. The Clean Fuel Standard became effective January 1, 2023. As of January 1, 2023, we are required to purchase compliance credits or allowances to reduce emissions or reduce the amount of carbon in the transportation fuels we sell at our terminal in Tacoma, Washington. Fuels with a carbon intensity below the CFS generate compliance credits while fuels with a carbon intensity above the CFS generate deficits. We record our compliance credits net of deficits in inventory and recognize expense as cost of product sales when we transfer the compliance credit to our customers. To the extent we have not purchased enough compliance credits to satisfy our obligations as of the balance sheet date, we record a liability for our obligation to purchase the compliance credits in accrued liabilities and recognize the expense in cost of product sales when we satisfy the compliance obligation.

(f) Property, plant and equipment

Depreciation is computed using the straight-line method. Estimated useful lives are 15 to 25 years for terminals and pipelines and 3 to 25 years for furniture, fixtures and equipment. All items of property, plant and equipment are carried at cost. Expenditures that increase capacity or extend useful lives are capitalized. Repairs and maintenance are expensed as incurred.

We evaluate long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset group may not be recoverable based on expected undiscounted future cash flows attributable to that asset group. If an asset group is impaired, the impairment loss to be recognized is the excess of the carrying amount of the asset group over its estimated fair value. We did not recognize any impairment charges during the three months ended March 31, 2025 and 2024.

11

TransMontaigne Partners LLC and Subsidiaries

Notes to consolidated financial statements (unaudited) (continued)

(g) Investments in unconsolidated affiliates

We account for our investments in unconsolidated affiliates, which we do not control but do have the ability to exercise significant influence over, using the equity method of accounting. Under this method, the investment is recorded at acquisition cost, increased by our proportionate share of any earnings and additional capital contributions and decreased by our proportionate share of any losses, distributions received and amortization of any excess investment. Excess investment is the amount by which our total investment exceeds our proportionate share of the book value of the net assets of the investment entity. We evaluate our investments in unconsolidated affiliates for impairment whenever events or circumstances indicate there is a loss in value of the investment that is other than temporary. In the event of impairment, we would record a charge to earnings to adjust the carrying amount to estimated fair value. We did not recognize any impairment charges during the three months ended March 31, 2025 and 2024.

(h) Environmental obligations

We accrue for environmental costs that relate to existing conditions caused by past operations when probable and reasonably estimable (see Note 10 of Notes to consolidated financial statements). Environmental costs include initial site surveys and environmental studies of potentially contaminated sites, costs for remediation and restoration of sites determined to be contaminated and ongoing monitoring costs, as well as fines, damages and other costs, including direct legal costs. Liabilities for environmental costs at a specific site are initially recorded, on an undiscounted basis, when it is probable that we will be liable for such costs, and a reasonable estimate of the associated costs can be made based on available information. Such an estimate includes our share of the liability for each specific site and the sharing of the amounts related to each site that will not be paid by other potentially responsible parties, based on enacted laws and adopted regulations and policies. Adjustments to initial estimates are recorded, from time to time, to reflect changing circumstances and estimates based upon additional information developed in subsequent periods. Estimates of our ultimate liabilities associated with environmental costs are difficult to make with certainty due to the number of variables involved, including the early stage of investigation at certain sites, the lengthy time frames required to complete remediation, technology changes, alternatives available and the evolving nature of environmental laws and regulations. We periodically file claims for insurance recoveries of certain environmental remediation costs with our insurance carriers under our comprehensive liability policies (see Note 4 of Notes to consolidated financial statements).

In connection with our acquisition of the Florida, Midwest, Brownsville, Texas, River and Southeast terminals and facilities, a third party agreed to indemnify us against certain potential environmental claims, losses and expenses. Based on our current knowledge, we expect that the active remediation projects subject to the benefit of this indemnification obligation are winding down and will not involve material additional claims, losses, and expenses.

(i) Asset retirement obligations

Asset retirement obligations are legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development or normal use of the asset. GAAP requires that the fair value of a liability related to the retirement of long-lived assets be recorded at the time a legal obligation is incurred. Once an asset retirement obligation is identified and a liability is recorded, a corresponding asset is recorded, which is depreciated over the remaining useful life of the asset. After the initial measurement, the liability is adjusted to reflect changes in the asset retirement obligation. If and when it is determined that a legal obligation has been incurred, the fair value of any liability is determined based on estimates and assumptions related to retirement costs, future inflation rates and interest rates. Our long-lived assets consist of above-ground storage facilities and underground pipelines. We are unable to predict if and when these long-lived assets will become completely obsolete and require dismantlement. We have not recorded an asset retirement obligation, or corresponding asset, because the future dismantlement and removal dates of our long-lived assets is indeterminable and the amount of any associated costs are believed to be insignificant. Changes in our assumptions and estimates may occur as a result of the passage of time and the occurrence of future events.

(j) Accounting for derivative instruments

Generally accepted accounting principles require us to recognize all derivative instruments at fair value in the consolidated balance sheets as assets or liabilities. Changes in the fair value of our derivative instruments are recognized in the consolidated statements of operations. At March 31, 2025 and December 31, 2024, our derivative instruments were limited to interest rate swap agreements. The fair value of our interest rate swap agreements are determined using a pricing model based on applicable swap rates and other observable market data. At March 31, 2025 and December 31, 2024, the fair value of our interest rate swap agreements was approximately $9.2 million and $19.1 million, respectively (see Notes 4 and 9 of Notes to consolidated financial statements).

Pursuant to the terms of the interest rate swap agreements, we pay a blended fixed rate and receive interest payments based on the one-month London Interbank Offered Rate (“LIBOR”) through July 17, 2023, and on the one-month Term Secured Overnight Financing Rate (“SOFR”) or Overnight Indexed Swap (“OIS”) compound SOFR for periods after July 17, 2023. The net difference to be paid or received under the interest rate swap agreements will be settled monthly and recognized as an adjustment to interest expense. For the three months ended March 31, 2025 and 2024, we recognized an unrealized gain (loss) on interest rate swap agreements of approximately ($9.9) million and $11.2 million, respectively.

Our interest rate swap agreements were as follows (in thousands, except blended fixed rate):

		Aggregate	Blended
Interest rate swap agreement term		notional amount	fixed rate
July 18, 2023 - August 18, 2025	$	500,000	2.87	%
August 18, 2023 - August 18, 2026	$	280,000	3.52	%
August 18, 2025 - August 18, 2026	$	500,000	3.31	%
August 18, 2026 - August 18, 2028	$	700,000	3.24	%

(k) Income taxes

No provision for United States federal income taxes has been reflected in the accompanying consolidated financial statements because we are treated as a partnership for federal income tax purposes. As a partnership, all income, gains, losses, expenses, deductions and tax credits generated by us flow up to our owners.

(l) Comprehensive income

Entities that report items of other comprehensive income have the option to present the components of net earnings (loss) and comprehensive income in either one continuous financial statement, or two consecutive financial statements. As we have no components of comprehensive income other than net earnings (loss), no statement of comprehensive income has been presented.

(m) Recent accounting pronouncements

In March 2024, the Securities and Exchange Commission (SEC) issued final climate-related disclosure rules under SEC Release No. 33-11275, The Enhancement and Standardization of Climate-Related Disclosures for Investors. Subject to certain exemptions, the rules will require annual disclosure of material greenhouse gas emissions as well as disclosure of governance, risk management and strategy related to material climate-related risks. In addition, the rules require (i) financial statement impacts of severe weather events and other natural conditions; (ii) a roll forward of carbon offset and renewable energy credit balances if material to the Company’s plan to achieve climate-related targets or goals; and (iii) material impacts on estimates and assumptions in the financial statements. The disclosure requirements will begin phasing in for annual periods beginning with the calendar year 2027. The rule is currently stayed pending

Notes to consolidated financial statements (unaudited) (continued)

resolution of various legal challenges. We are currently evaluating the final rules to determine its impact on our consolidated financial statements once the final implementation timeline is concluded.

In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement, which is intended to improve the disclosure about certain operating expenses primarily through enhanced disclosure of cost of sales and selling, general and administrative expenses. The guidance is effective for annual reporting periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The guidance can be applied on either a prospective or a retrospective basis at our election. We are currently evaluating the impact the guidance will have on our consolidated financial statements and our plan for adoption.

(3) CONCENTRATION OF CREDIT RISK AND TRADE ACCOUNTS RECEIVABLE

We conduct our operations in the United States along the Gulf Coast, in the Midwest, in Houston and Brownsville, Texas, along the Mississippi and Ohio rivers, in the Southeast and along the West Coast. We have a concentration of trade receivable balances due from companies engaged in the trading, distribution and marketing of refined products, renewable products and crude oil. These concentrations of customers may affect our overall credit risk in that the customers may be similarly affected by changes in economic, regulatory or other factors. Our customers’ historical financial and operating information is analyzed prior to extending credit. We manage our exposure to credit risk through credit analysis, credit approvals, credit limits and monitoring procedures, and for certain transactions we may request letters of credit, prepayments or guarantees.

Trade accounts receivable consists of the following (in thousands):

	March 31,		December 31,
	2025		2024

(5) ASSETS HELD FOR SALE

On January 22, 2025, the Company announced that it had entered into an agreement for the sale of our terminal facilities on Fisher Island Miami, Florida in our Gulf Coast terminals business segment. The Fisher Island terminal has active capacity of approximately 700,000 barrels for the storage of marine fuels. The purchase price is approximately $180 million. The closing of the sale is expected to occur in the third quarter of 2025, subject to customary closing conditions. Upon closing we will retain all assets and liabilities associated with the maintenance and operations of the Fisher Island terminal, excluding land.

Following the closing, we will lease the terminal from the buyer to allow us to continue servicing our current customer agreements through approximately May 2027. At the end of the lease, we plan to abandon the terminal property, plant, and equipment, net. Accordingly, we will apply abandonment accounting and accelerate the depreciation of the terminal property, plant and equipment, net of approximately $5.8 million, over the course of the lease term, which is expected to conclude in May 2027.

As a result, we have determined that the Fisher Island terminal land of approximately $7.1 million should be classified as held for sale at March 31, 2025 and December 31, 2024. The committed and planned sale and abandonment does not, however, represent a strategic shift that will have a major effect on our operations and financial results. Therefore, the effects of the planned sale and abandonment have not been reported as discontinued operations within the consolidated financial statements.

(6) PROPERTY, PLANT AND EQUIPMENT, NET

Property, plant and equipment, net was as follows (in thousands):

	March 31,		December 31,
	2025		2024
Land	$	96,880	$	96,880
Terminals, pipelines and equipment		1,455,868		1,446,804

Less accumulated depreciation		(789,557)		(772,330)
	$	802,738	$	808,274

At both March 31, 2025 and December 31, 2024, property, plant and equipment, net utilized by our customers in revenue operating lease arrangements consisted of approximately $561.0 million of terminals, pipelines and equipment. The terminals, pipelines and equipment primarily relates to our storage tanks and associated internal piping.

(7) GOODWILL

Goodwill was as follows (in thousands):

	March 31,		December 31,
	2025		2024
Brownsville terminals	$	8,485	$	8,485
West Coast terminals		10,101		10,101
	$	18,586	$	18,586

Goodwill is required to be tested for impairment annually unless events or changes in circumstances indicate it is more likely than not that an impairment loss has been incurred at an interim date. Our annual test for the impairment of

16

TransMontaigne Partners LLC and Subsidiaries

Notes to consolidated financial statements (unaudited) (continued)

goodwill is performed as of December 31. The impairment test is performed at the reporting unit level. Our reporting units are our business segments (see Note 16 of Notes to consolidated financial statements). The fair value of each reporting unit is determined on a stand-alone basis from the perspective of a market participant and represents an estimate of the price that would be received to sell the unit as a whole in an orderly transaction between market participants at the measurement date. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered to be impaired.

At March 31, 2025 and December 31, 2024, our Brownsville and West Coast terminals contained goodwill. We did not recognize any goodwill impairment charges during the three months ended March 31, 2025 and 2024 or during the year ended December 31, 2024 for these reporting units. However, an increase in the assumed market participants’ weighted average cost of capital, the loss of a significant customer, the disposition of significant assets, or an unforeseen increase in the costs to operate and maintain the Brownsville or West Coast terminals could result in the recognition of an impairment charge in the future.

(8) INVESTMENTS IN UNCONSOLIDATED AFFILIATES

Notes to consolidated financial statements (unaudited) (continued)

On October 28, 2024, the Company, as parent guarantor, and TransMontaigne Operating Company L.P., our wholly owned subsidiary, entered into Amendment No. 3 to the Credit Agreement, which provides for, among other things, (i) the reduction of the applicable margin of the senior secured term loans under the Credit Agreement (the “Repricing”) and (ii) the removal of the credit spread adjustment from the Term SOFR applicable to the senior secured term loans under the Credit Agreement. After giving effect to the Repricing and the removal of the credit spread adjustment, senior secured term loans under the Credit Agreement accrue interest at a per annum rate equal to, at our election, either a Term SOFR plus an applicable margin of 3.25% or an alternate base rate plus an applicable margin of 2.25%. The other terms and conditions of the Credit Agreement, as amended by Amendment No. 3, remain unchanged.

Prior to October 28, 2024, we could elect to have loans under the Credit Agreement bear interest, at either a Term SOFR plus 0.11448% (subject to a 0.50% floor) plus an applicable margin of 3.50% or an alternate base rate plus an applicable margin of 2.50% per annum. Thereafter, Amendment No. 3 rates apply to the senior secured term loans. We are also required to pay (i) a letter of credit fee of 3.50% per annum on the aggregate face amount of all outstanding letters of credit, (ii) to the issuing lender of each letter of credit, a fronting fee of no less than 0.125% per annum on the outstanding amount of each such letter of credit and (iii) commitment fees of 0.50% per annum on the daily unused amount of the revolving credit facility, in each case quarterly in arrears.

After giving effect to the Extension and RCF Repricing, (i) the maturity date of the revolving credit facility shall be the earlier of August 31, 2029 or, to the extent that any senior secured term loans under the Credit Agreement remain outstanding, the date that is ninety-one (91) days prior to the maturity date of such senior secured term loans under the Credit Agreement (taking into account any extensions or refinancings thereof) and (ii) loans under the revolving credit facility accrue interest at a per annum rate equal to, at our election, either a Term SOFR plus an applicable margin of 3.00% or an alternate base rate plus an applicable margin of 2.00%. The other terms and conditions of the Credit Agreement, as amended by Amendment No. 4, remain unchanged.

The Credit Agreement contains various covenants, including, but not limited to, limitations on the incurrence of indebtedness, permitted investments, liens on assets, making distributions, transactions with affiliates, mergers, consolidations, dispositions of assets and other provisions customary in similar types of agreements. The Credit Agreement requires compliance with (a) a consolidated debt service coverage ratio of no less than 1.1 to 1.0 and (b) if the aggregate outstanding amount of all revolving loans and drawn letters of credit exceeds an amount equal to 35% of the aggregate revolving commitments, a consolidated senior secured net leverage ratio of no greater than 6.75 to 1.00. We were in compliance with all financial covenants as of and during the three months ended March 31, 2025 and 2024 and the year ended December 31, 2024.

For the three months ended March 31, 2025 and 2024, the weighted average interest rate on borrowings was approximately 6.8% and 7.4%, respectively. At both March 31, 2025 and December 31, 2024, our outstanding letters of credit were approximately $0.4 million.

Senior notes. On February 12, 2018, the Company and TLP Finance Corp., our wholly owned subsidiary, issued at par $300 million of 6.125% senior notes. On February 21, 2025, the Company closed on our offering of $500 million aggregate principal amount of 8.500% senior unsecured notes due in 2030 at an issue price of 100% in a private offering that is exempt from the registration requirements of the Securities Act of 1933, as amended. The senior unsecured notes are guaranteed on a senior unsecured basis by all of the Company’s subsidiaries that guarantee our Credit Agreement. Proceeds from the $500 million senior unsecured notes were used to redeem all of our 6.125% senior notes due in 2026 of approximately $299.9 million, fund distributions to TLP Finance Holdings, LLC of approximately $172.8 million to repay TLP Finance Holdings, LLC’s term loan due in 2025 and fees and expenses in connection with

the transaction, repay borrowings under our revolving credit facility of approximately $4.0 million, and approximately $9.2 million of debt issuance costs, with the remainder used for general corporate purposes.

The Company is voluntarily filing with the Securities and Exchange Commission pursuant to the covenants contained in the 6.125% senior notes and beginning February 21, 2025, the 8.500% senior unsecured notes. These notes contain customary covenants (including those relating to our voluntary filing of this Quarterly Report on Form 10-Q and certain restrictions and obligations with respect to types of payments we may make, indebtedness we may incur, transactions we may pursue, or changes in our control) and customary events of default (including those relating to monetary defaults, covenant defaults, cross defaults and bankruptcy events). We may, at any time and from time to time, seek to retire or purchase our outstanding debt through cash purchases, open-market purchases, privately negotiated transactions or otherwise. Such repurchases, if any, will be upon such terms and at such prices as we may determine, and will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

TransMontaigne Partners LLC has no independent assets or operations unrelated to its investments in its consolidated subsidiaries. TLP Finance Corp. has no assets or operations. Our operations are conducted by subsidiaries of TransMontaigne Partners LLC through our 100% owned operating company subsidiary, TransMontaigne Operating Company L.P. None of the assets of TransMontaigne Partners LLC or a guarantor represent restricted net assets pursuant to the guidelines established by the Securities and Exchange Commission.

(12) DEFERRED COMPENSATION EXPENSE

We have a savings and retention plan to compensate certain employees who provide services to the Company. The purpose of the savings and retention plan is to provide for the reward and retention of participants by providing them with awards that vest over future service periods. Awards under the plan with respect to individuals providing services to the Company generally become vested as to 50% of a participant’s annual award as of the first day of the month that falls closest to the second anniversary of the grant date, and the remaining 50% as of the first day of the month that falls closest to the third anniversary of the grant date, subject to earlier vesting upon a participant’s attainment of the age and length of service thresholds, retirement, death or disability, involuntary termination without cause, or termination of a participant’s employment following a change in control of the Company as specified in the plan. The awards are increased for the value of any accrued growth based on underlying investments deemed made with respect to the awards. The awards (including any accrued growth relating thereto) are subject to forfeiture until the vesting date. A person will satisfy the age and length of service thresholds of the plan upon the attainment of the earliest of (a) age sixty, (b) age fifty-five and ten years of service as an officer of the Company or any of its affiliates or predecessors, or (c) age fifty and twenty years of service as an employee of the Company or any of its affiliates or predecessors.

We have the intent and ability to settle the savings and retention plan awards in cash, and accordingly, we account for the awards as accrued liabilities. For savings and retention plan awards to employees, approximately $0.8 million and $0.9 million is included in deferred compensation expense for the three months ended March 31, 2025 and 2024, respectively.

On September 14, 2023, an indirect parent of the Company granted class B units in the indirect parent of the Company to the officers of TMC. On September 14, 2023, an indirect parent of the Company modified existing class B units in the indirect parent of the Company to the officers of TMC. For the three months ended March 31, 2025 and 2024, we recognized approximately $0.2 million and $1.0 million, respectively, of deferred compensation expense in our consolidated statements of operations, non-cash contribution from parent entities in our consolidated statements of equity and non-cash equity-based compensation in our consolidated statements of cash flows related to the class B units.

(13) COMMITMENTS AND CONTINGENCIES

Lessee operating lease commitments. We lease property including corporate offices, vehicles and land. We determine if an arrangement is a lease at inception and evaluate identified leases for operating or finance lease treatment at lease commencement. Operating or finance lease right-of-use assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Our leases have remaining lease terms of less than one year to 46 years, some of which have options to extend or terminate the lease. For purposes of calculating operating lease liabilities, lease terms may be deemed to include options to extend or terminate the lease when it is reasonably certain that we will exercise that option.

Operating right-of-use assets and operating lease liabilities are recognized based on the present value of the lease payments over the lease term at commencement date. The additions to right-of-use assets obtained from new operating lease liabilities are treated as non-cash transactions that do not impact the consolidated statements of cash flows. The Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. We determined our incremental borrowing rate using the borrowing rate of our debt agreements. The terms of our corporate offices, vehicles and land leases are in line with the Credit Agreement, our primary finance mechanism. We have certain land and vehicle lease agreements with lease and non-lease components, which are accounted for separately. Non-lease components include payments for taxes and other operating and maintenance expenses incurred by the lessor but payable by us in connection with the leasing arrangement. During the three months ended March 31, 2025 and 2024, the Company was party to certain subleasing arrangements whereby the Company, as the primary obligor on the lease, has recognized sublease income for lease payments made by affiliates to the lessor.

Following are components of our lease costs (in thousands):

Contractual commitments. At March 31, 2025, we have contractual commitments of approximately $28.4 million for the supply of services, labor and materials related to capital projects that currently are under development. We expect that these contractual commitments will primarily be paid within a year.

Legal proceedings. We are party to various legal, regulatory and other matters arising from the day-to-day operations of our business that may result in claims against us. While the ultimate impact of any proceedings cannot be predicted with certainty, our management believes that the resolution of any of our pending legal proceedings will not have a material adverse effect on our business, financial position, results of operations or cash flows.

(14) DISCLOSURES ABOUT FAIR VALUE

GAAP defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. GAAP also establishes a fair value hierarchy that prioritizes the use of higher-level inputs for valuation techniques used to measure fair value. The three levels of the fair value hierarchy are: (1) Level 1 inputs, which are quoted prices (unadjusted) in active markets for identical assets or liabilities; (2) Level 2 inputs, which are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and (3) Level 3 inputs, which are unobservable inputs for the asset or liability.

The fair values of the following financial instruments represent our best estimate of the amounts that would be received to sell those assets or that would be paid to transfer those liabilities in an orderly transaction between market participants at that date. Our fair value measurements maximize the use of observable inputs. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the fair value measurement reflects our judgments about the assumptions that market participants would use in pricing the asset or liability based on the best information available in the circumstances. There were no transfers into or out of Levels 1, 2, and 3 during the three months ended March 31, 2025 and 2024. The following methods and assumptions were used to estimate the fair value of financial instruments at March 31, 2025 and December 31, 2024.

Cash equivalents. The carrying amount approximates fair value because of the short-term maturity of these instruments. The fair value is categorized in Level 1 of the fair value hierarchy.

Derivative instruments. The carrying amount of our interest rate swaps is equal to fair value and was determined using a pricing model based on the applicable swap rates and other observable market data. The fair value is categorized in Level 2 of the fair value hierarchy.

24

TransMontaigne Partners LLC and Subsidiaries

Notes to consolidated financial statements (unaudited) (continued)

Debt. The estimated fair value of our $1,116.0 million senior secured term loans at March 31, 2025 was approximately $1,111.8 million based on observable market trades. The estimated fair value of our $500 million senior unsecured notes at March 31, 2025 was approximately $497.2 million based on observable market trades. The carrying amount of our revolving credit facility debt approximates fair value since borrowings under the facility bear interest at current market interest rates. The fair value of our debt is categorized in Level 2 of the fair value hierarchy.

Non-financial assets. The Company’s non-financial assets, which primarily consist of property and equipment, right-of-use assets, goodwill and other intangible assets, are not required by GAAP to be carried at fair value on a recurring basis and are reported at carrying value. The fair values of these assets are determined, as required by GAAP, based on Level 3 measurements, including estimates of the amount and timing of future cash flows based upon historical experience, expected market conditions, and management’s plans.

(15) REVENUE FROM CONTRACTS WITH CUSTOMERS

The majority of our terminaling services agreements contain minimum payment arrangements, resulting in a fixed amount of revenue recognized, which we refer to as “firm commitments” and are accounted for in accordance with ASC 842, Leases (“ASC 842 revenue”). The remainder is recognized in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606 revenue”).

capital projects. Upon completion of the projects, our customers have paid us amounts that will be recognized as revenue on a straight-line basis over the remaining term of the agreements. Collectively, the differences between amounts billed and revenue recognized under ASC 606 and ASC 842 are recorded as contract liabilities. These liabilities are presented as deferred revenue in our consolidated balance sheets. We record customer advances and deposits when payments are received from customers in advance of the terminaling services being provided, resulting in a contract liability accounted for under ASC 606 and ASC 842. This liability is presented as accrued liabilities in our consolidated balance sheets (see Note 10 of Notes to consolidated financial statements).

(16) BUSINESS SEGMENTS

We provide integrated terminaling, storage, transportation and related services to companies engaged in the trading, distribution and marketing of refined petroleum products, renewable products, crude oil, chemicals, fertilizers and other liquid products. In addition, we sell refined and renewable products to major fuel producers and marketers in the Pacific Northwest at our terminal in Tacoma, Washington. Our chief operating decision maker is the Company’s chief executive officer. The Company’s chief executive officer reviews the financial performance of our business segments using disaggregated financial information about “net margins”. Our chief operating decision maker considers the actual “net margins” as compared to the “net margins” for (i) the relevant prior period actual results, (ii) budget and (iii) guidance on a quarterly basis for purposes of making operating decisions and assessing financial performance. “Net margins” is composed of revenue less cost of product sales and operating costs and expenses. The cost of product sales at our terminal in Tacoma, Washington includes product purchases and transportation costs. The operating costs and expenses of our operations include wages and employee benefits, utilities, communications, repairs and maintenance, rent, property taxes, vehicle expenses, environmental compliance costs, contract services, legal fees and materials and supplies needed to operate our terminals. Accordingly, we present “net margins” for each of our business segments: (i) Gulf Coast terminals, (ii) Midwest terminals, (iii) Brownsville terminals including management of Frontera, (iv) River terminals, (v) Southeast terminals, (vi) West Coast terminals and (vii) Central services. Our Central services segment primarily represents the costs of employees performing operating oversight functions, engineering, health, safety and environmental services to our terminals and terminals that we operate. In addition, Central services represent the cost of employees at standalone affiliate terminals that we operate or manage. We receive a fee from these affiliates based on our costs incurred. Accounting policies for each segment are the same as the accounting policies described in Note 1 of Notes to the consolidated financial statements.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

A summary of the significant accounting policies that we have adopted and followed in the preparation of our consolidated financial statements is detailed in Note 1 of Notes to consolidated financial statements as of March 31, 2025 and December 31, 2024 and for the three months ended March 31, 2025 and 2024. Certain of these accounting policies require the use of estimates. In management’s opinion, the estimate of useful lives of our plant and equipment are subjective in nature, require the exercise of judgment and involve complex analyses. These estimates are based on our knowledge and understanding of current conditions and actions we may take in the future. Changes in these estimates will occur as a result of the passage of time and the occurrence of future events. Subsequent changes in these estimates may have a significant impact on our financial condition and results of operations.

RESULTS OF OPERATIONS—THREE MONTHS ENDED MARCH 31, 2025 AND 2024

We operate our business and report our results of operations in seven principal business segments: (i) Gulf Coast terminals, (ii) Midwest terminals, (iii) Brownsville terminals including management of Frontera, (iv) River terminals, (v) Southeast terminals, (vi) West Coast terminals and (vii) Central services. Our Central services segment primarily represents the costs of employees performing operating oversight functions, engineering, health, safety and environmental services to our terminals and terminals that we operate. In addition, Central services represent the cost of employees at standalone affiliate terminals that we operate or manage. We receive a fee from these affiliates based on our costs incurred.

The following discussion and analysis of the results of operations and financial condition should be read in conjunction with the accompanying unaudited consolidated financial statements.

ANALYSIS OF TERMINAL REVENUE

Terminaling services fees. Our terminaling services agreements are structured as either throughput agreements or storage agreements. Our throughput agreements contain provisions that require our customers to make minimum payments, which are based on contractually established minimum volume of throughput of the customer’s product at our facilities over a stipulated period of time. Due to this minimum payment arrangement, we recognize a fixed amount of revenue from the customer over a certain period of time, even if the customer throughputs less than the minimum volume of product during that period. In addition, if a customer throughputs a volume of product exceeding the minimum volume, we would recognize additional revenue on this incremental volume. Our storage agreements require our customers to make minimum payments based on the volume of storage capacity available to the customer under the agreement, which results in a fixed amount of recognized revenue.

We refer to the fixed amount of revenue recognized pursuant to our terminaling services agreements as being “firm commitments.” Revenue recognized in excess of firm commitments and revenue recognized based solely on the volume of product distributed or injected are referred to as “ancillary.” In addition, “ancillary” revenue also includes fees received from ancillary services including heating and mixing of stored products, product transfer, railcar handling, butane blending, proceeds from the sale of product gains, wharfage and vapor recovery.

Included in management fees for the three months ended March 31, 2025 and 2024, are fees charged to affiliates of approximately $2.6 million and $4.1 million, respectively.

ANALYSIS OF PRODUCT SALES, GROSS MARGIN

Product sales, gross margin. Our product sales revenue refers to the sale of refined and renewable products at our terminal in Tacoma, Washington. Product sales revenue pricing is contractually specified and is recognized at a point in time when our customers take control and legal title of the commodities purchased. Product sales revenue is recorded gross of cost of product sales, which includes product purchases and transportation costs.

The product sales, gross margin was as follows (in thousands):

Product sales, gross margin	$	5,248	$	5,408

The increase in product sales and cost of product sales for the three months ended March 31, 2025, is primarily a result of increased product prices and volumes.

ANALYSIS OF COSTS AND EXPENSES

The operating costs and expenses of our operations include wages and employee benefits, utilities, communications, repairs and maintenance, rent, property taxes, vehicle expenses, environmental compliance costs, contract services, legal fees and materials and supplies needed to operate our terminals and pipelines. Consistent with historical trends across our terminaling and transportation facilities, repairs and maintenance expenses can vary from period to period based on project maintenance schedules and other factors such as weather.

General and administrative expenses also include third party accounting costs associated with annual and quarterly reports and tax return preparation and distribution, and legal fees. The general and administrative expenses were approximately $7.4 million and $8.9 million for the three months ended March 31, 2025 and 2024, respectively. The decrease in general and administrative expenses for the three months ended March 31, 2025 is primarily due to our administration of payroll for the ArcLight affiliate owned Lucknow-Highspire Terminals, LLC ending on December 31, 2024.

Insurance expenses include charges for insurance premiums to cover costs of insuring activities such as property, casualty, pollution, automobile, directors’ and officers’ liability, and other insurable risks.

ANALYSIS OF INVESTMENTS IN UNCONSOLIDATED AFFILIATES

Our investments in unconsolidated affiliates include a 42.5% Class A ownership interest in BOSTCO, a 30% ownership interest in Olympic Pipeline Company, a 51% ownership interest in SeaPort Midstream and a 50% ownership interest in Frontera. BOSTCO is a terminal facility located on the Houston Ship Channel that encompasses approximately 7.1 million barrels of distillate, residual and other black oil product storage. Class A and Class B ownership interests in BOSTCO share in cash distributions on a 96.5% and 3.5% basis, respectively. Class B ownership interests do not have voting rights and are not required to make capital investments. Olympic Pipeline Company is a 400-mile interstate refined petroleum products pipeline system running from Blaine, Washington to Portland, Oregon and a refined and renewable products terminal in Bayview, Washington. SeaPort Midstream is two terminal facilities located in Seattle, Washington and Portland, Oregon that encompasses approximately 1.3 million barrels of refined and renewable product storage. Frontera is a terminal facility located in Brownsville, Texas that encompasses approximately 1.7 million barrels of light petroleum product storage, as well as related ancillary facilities.

Earnings (loss) from investments in unconsolidated affiliates was as follows (in thousands):

Total earnings from investments in unconsolidated affiliates	$	4,444	$	3,806

The decrease in earnings from our investment in BOSTCO for the three months ended March 31, 2025 is primarily attributable to decreased ancillary revenue.

The increase in earnings from our investment in Olympic Pipeline Company for the three months ended March 31, 2025 is primarily attributable to decreased costs and expenses related to an Olympic Pipeline Company remediation project in 2024.

Cash distributions received from unconsolidated affiliates was as follows (in thousands):

LIQUIDITY AND CAPITAL RESOURCES

Our primary liquidity needs are to fund our debt service obligations, working capital requirements and capital projects, including additional investments and expansion, development and acquisition opportunities. We expect to fund any additional investments, capital projects and future expansion, development and acquisition opportunities with cash flows from operations and additional borrowings under our revolving credit facility.

Net cash provided by (used in) operating activities, investing activities and financing activities were as follows (in thousands):

	Three months ended

Net cash used in investing activities	$	(5,030)	$	(16,714)
Net cash used in financing activities	$	(1,770)	$	(19,196)

The approximately $24.2 million decrease in net cash provided by operating activities is primarily attributable to the timing of working capital requirements.

The approximately $11.7 million decrease in net cash used in investing activities is primarily related to receiving an approximately $5.1 million member loan payment from Olympic Pipeline Company and an approximately $6.6 million decrease in maintenance capital spend.

Additional investments and expansion capital projects at our terminals have been approved and currently are, or will be, under construction with estimated completion dates through 2026. At March 31, 2025, the remaining expenditures to complete the approved projects are estimated to be approximately $25.0 million. These expenditures primarily relate to the construction costs associated with the expansion of our West Coast operations.

The approximately $17.4 million decrease in net cash used in financing activities is primarily related to an approximately $139.1 million increase in distributions to TLP Finance Holdings, LLC for debt service in 2025 as compared to 2024 and an approximately $34.4 million decrease in borrowings under the Credit Agreement; offset by an approximately $200.1 million increase in senior unsecured notes indebtedness. As discussed below, on February 21, 2025, the Company closed on our offering of $500 million aggregate principal amount of 8.500% senior unsecured notes due in 2030. Proceeds from the $500 million senior unsecured notes were used to redeem all of our 6.125% senior notes due in 2026 of approximately $299.9 million, fund distributions to TLP Finance Holdings, LLC of approximately $172.8 million to repay TLP Finance Holdings, LLC’s term loan due in 2025 and fees and expenses in connection with the transaction, repay borrowings under our revolving credit facility of approximately $4.0 million, and approximately $9.2 million of debt issuance costs, with the remainder used for general corporate purposes.

Credit agreement. On November 17, 2021, the Company, as parent guarantor, and TransMontaigne Operating Company L.P., our wholly owned subsidiary, entered into the Credit Agreement (“Credit Agreement”) for $1 billion senior secured term loans and a $150 million revolving credit facility, with a letter of credit subfacility of $35 million. On April 15, 2024, we entered into Amendment No. 2 to the Credit Agreement for a new tranche of senior secured term loans in an aggregate principal amount of $150 million. The other terms and conditions of the Credit Agreement were unchanged.

Proceeds from the $150 million senior secured term loans were used as follows (in thousands):

Repayment of revolving credit facility	$	110,401
Distributions to TLP Finance Holdings, LLC for debt service		36,677
Debt issuance costs		2,922
Proceeds from $150 million senior secured term loans	$	150,000

The senior secured term loans will mature on November 17, 2028. Our obligations under the Credit Agreement are guaranteed by the Company, TransMontaigne Operating Company L.P. and all of its subsidiaries, and secured by a first priority security interest in favor of the lenders in substantially all of the Company’s, TransMontaigne Operating Company L.P.’s and all of its subsidiaries’ assets, including our investments in unconsolidated affiliates.

On October 28, 2024, the Company, as parent guarantor, and TransMontaigne Operating Company L.P., our wholly owned subsidiary, entered into Amendment No. 3 to the Credit Agreement, which provides for, among other things, (i) the reduction of the applicable margin of the senior secured term loans under the Credit Agreement (the

36

“Repricing”) and (ii) the removal of the credit spread adjustment from the Term SOFR applicable to the senior secured term loans under the Credit Agreement. After giving effect to the Repricing and the removal of the credit spread adjustment, senior secured term loans under the Credit Agreement accrue interest at a per annum rate equal to, at our election, either a Term SOFR plus an applicable margin of 3.25% or an alternate base rate plus an applicable margin of 2.25%. The other terms and conditions of the Credit Agreement, as amended by Amendment No. 3, remain unchanged.

Prior to October 28, 2024, we could elect to have loans under the Credit Agreement bear interest, at either a Term SOFR plus 0.11448% (subject to a 0.50% floor) plus an applicable margin of 3.50% or an alternate base rate plus an applicable margin of 2.50% per annum. Thereafter, Amendment No. 3 rates apply to the senior secured term loans. We are also required to pay (i) a letter of credit fee of 3.50% per annum on the aggregate face amount of all outstanding letters of credit, (ii) to the issuing lender of each letter of credit, a fronting fee of no less than 0.125% per annum on the outstanding amount of each such letter of credit and (iii) commitment fees of 0.50% per annum on the daily unused amount of the revolving credit facility, in each case quarterly in arrears.

On February 5, 2025, the Company, as parent guarantor, and TransMontaigne Operating Company L.P., our wholly owned subsidiary, entered into Amendment No. 4 to the Credit Agreement which provides for, among other things, (i) the extension of the maturity date with respect to the revolving credit facility (the “Extension”) and (ii) the reduction of the applicable margin of the loans under the revolving credit facility (the “RCF Repricing”). After giving effect to the Extension and RCF Repricing, (i) the maturity date of the revolving credit facility shall be the earlier of August 31, 2029 or, to the extent that any senior secured term loans under the Credit Agreement remain outstanding, the date that is ninety-one (91) days prior to the maturity date of such senior secured term loans under the Credit Agreement (taking into account any extensions or refinancings thereof) and (ii) loans under the revolving credit facility accrue interest at a per annum rate equal to, at our election, either a Term SOFR plus an applicable margin of 3.00% or an alternate base rate plus an applicable margin of 2.00%. The other terms and conditions of the Credit Agreement, as amended by Amendment No. 4, remain unchanged.

The Credit Agreement contains various covenants, including, but not limited to, limitations on the incurrence of indebtedness, permitted investments, liens on assets, making distributions, transactions with affiliates, mergers, consolidations, dispositions of assets and other provisions customary in similar types of agreements. The Credit Agreement requires compliance with (a) a consolidated debt service coverage ratio of no less than 1.1 to 1.0 and (b) if the aggregate outstanding amount of all revolving loans and drawn letters of credit exceeds an amount equal to 35% of the aggregate revolving commitments, a consolidated senior secured net leverage ratio of no greater than 6.75 to 1.00. We were in compliance with all financial covenants as of and during the three months ended March 31, 2025 and 2024 and the year ended December 31, 2024.

If we were to fail a financial performance covenant, or any other covenant contained in the Credit Agreement, we would seek a waiver from our lenders under such facility. If we were unable to obtain a waiver from our lenders and the default remained uncured after any applicable grace period, we would be in breach of the Credit Agreement, and the lenders would be entitled to declare all outstanding borrowings immediately due and payable.

Senior notes. On February 12, 2018, the Company and TLP Finance Corp., our wholly owned subsidiary, issued at par $300 million of 6.125% senior notes, due in 2026. On February 21, 2025, the Company closed on our offering of $500 million aggregate principal amount of 8.500% senior unsecured notes due in 2030 at an issue price of 100% in a private offering that is exempt from the registration requirements of the Securities Act of 1933, as amended. The senior unsecured notes are guaranteed on a senior unsecured basis by all of the Company’s subsidiaries that guarantee our Credit Agreement. Proceeds from the $500 million senior unsecured notes were used to redeem all of our 6.125% senior notes due in 2026 of approximately $299.9 million, fund distributions to TLP Finance Holdings, LLC of approximately $172.8 million to repay TLP Finance Holdings, LLC’s term loan due in 2025 and fees and expenses in connection with the transaction, repay borrowings under our revolving credit facility of approximately $4.0 million, and approximately $9.2 million of debt issuance costs, with the remainder used for general corporate purposes.

The Company is voluntarily filing with the Securities and Exchange Commission pursuant to the covenants contained in the 6.125% senior notes and beginning February 21, 2025, the 8.500% senior unsecured notes. These notes contain customary covenants (including those relating to our voluntary filing of this Quarterly Report on Form 10-Q and certain restrictions and obligations with respect to types of payments we may make, indebtedness we may incur, transactions we may pursue, or changes in our control) and customary events of default (including those relating to monetary defaults, covenant defaults, cross defaults and bankruptcy events). We may, at any time and from time to time,

38

seek to retire or purchase our outstanding debt through cash purchases, open-market purchases, privately negotiated transactions or otherwise. Such repurchases, if any, will be upon such terms and at such prices as we may determine, and will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The information contained in this Item 3 updates, and should be read in conjunction with, information set forth in Part II, Item 7A of our Annual Report on Form 10-K, filed with the Securities and Exchange Commission on March 27, 2025 in addition to the interim unaudited consolidated financial statements, accompanying notes and Management’s Discussion and Analysis of Financial Condition and Results of Operations presented in Part 1, Items 1 and 2 of this Quarterly Report on Form 10-Q. There are no material changes in the market risks faced by us from those reported in our Annual Report on Form 10-K for the year ended December 31, 2024.

Market risk is the risk of loss arising from adverse changes in market rates and prices. A principal market risk to which we are exposed is interest rate risk associated with borrowings under the Credit Agreement. Borrowings under the Credit Agreement bear interest at either a Term SOFR plus 0.11448% (subject to a 0.50% floor) plus an applicable margin of 3.50% or an alternate base rate plus an applicable margin of 2.50% per annum through October 27, 2024. On October 28, 2024, the Company entered into an amendment to the Credit Agreement, which provides for, among other things, (i) the reduction of the applicable margin of the senior secured term loans under the Credit Agreement (the “Repricing”) and (ii) the removal of the credit spread adjustment from the Term SOFR applicable to the senior secured term loans under the Credit Agreement. After giving effect to the Repricing and the removal of the credit spread adjustment, senior secured term loans under the Credit Agreement accrue interest at a per annum rate equal to, at our election, either a Term SOFR plus an applicable margin of 3.25% or an alternate base rate plus an applicable margin of 2.25%.

On February 5, 2025, the Company, as parent guarantor, and TransMontaigne Operating Company L.P., our wholly owned subsidiary, entered into Amendment No. 4 to the Credit Agreement which provides for, among other things, (i) the extension of the maturity date with respect to the revolving credit facility (the “Extension”) and (ii) the reduction of the applicable margin of the loans under the revolving credit facility (the “RCF Repricing”). After giving effect to the Extension and RCF Repricing, (i) the maturity date of the revolving credit facility shall be the earlier of August 31, 2029 or, to the extent that any senior secured term loans under the Credit Agreement remain outstanding, the date that is ninety-one (91) days prior to the maturity date of such senior secured term loans under the Credit Agreement (taking into account any extensions or refinancings thereof) and (ii) loans under the revolving credit facility accrue interest at a per annum rate equal to, at our election, either a Term SOFR plus an applicable margin of 3.00% or an alternate base rate plus an applicable margin of 2.00%. The other terms and conditions of the credit facility, as amended by the amendments, remain unchanged.

We manage a portion of our interest rate risk with interest rate swaps, which reduce our exposure to changes in interest rates by converting variable interest rates to fixed interest rates. At March 31, 2025, $780 million of our outstanding borrowings under the Credit Agreement was converted from variable interest rates to fixed interest rates with interest rate swap agreements, the majority of which expire through August 18, 2028. Pursuant to the terms of the interest rate swap agreements, we pay a blended fixed rate and receive interest payments based the one-month Term SOFR or OIS compound SOFR. The net difference to be paid or received under the interest rate swap agreements will be settled monthly and recognized as an adjustment to interest expense. At March 31, 2025, we had outstanding borrowings of $1,116.0 million under the Credit Agreement. Based on the outstanding balance of our variable-interest-rate debt, assuming market interest rates increase or decrease by 100 basis points, the potential annual increase or decrease in interest expense is approximately $3.4 million.

We sell refined and renewable products to major fuel producers and marketers in the Pacific Northwest at our terminal in Tacoma, Washington. Our direct exposure to changes in commodity prices is limited to these product sales and the value of product gains and losses arising from terminaling services agreements with certain customers, which accounts for a small portion of our revenue. We do not use derivative commodity instruments to manage the commodity risk associated with the product we may own at any given time.

ITEM 4. CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit to the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified by the Commission’s rules and forms, and that information is accumulated and communicated to the management of the Company, including the Company’s principal executive and principal financial officer (whom we refer to as the Certifying Officers), as appropriate to allow timely decisions regarding required disclosure. The management of the Company evaluated, with the participation of the Certifying Officers, the effectiveness of our disclosure controls and procedures as of March 31, 2025, pursuant to Rule 13a-15(b) under the Exchange Act. Based upon that evaluation, the Certifying Officers concluded that, as of March 31, 2025, our disclosure controls and procedures were effective. There were no changes in our internal control over financial reporting that occurred during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
