Recent Developments

In May 2026, Navios Partners agreed to acquire four newbuilding scrubber-fitted VLCC tankers from an unrelated third party, for an aggregate purchase price of $482.0 million. The vessels are expected to be delivered into Navios Partners’ fleet during the second half of 2028. Each vessel has been chartered-out for a firm period of approximately five years at $47,763 net per day, with charterer’s option for one additional year at $52,650 net per day. Navios Partners has also secured options to acquire two plus two newbuilding VLCC tankers.

In April and May 2026, Navios Partners took delivery of a 2026-built Aframax/LR2 scrubber-fitted tanker vessel of 117,059 dwt, a 2026-built MR2 product tanker vessel of 49,996 dwt and a 2026-built 7,900 TEU methanol-ready and scrubber-fitted containership.

On April 29, 2026, Navios Partners completed the listing application with Euronext Oslo Børs for its senior unsecured bonds due November 2030 (the “2030 Bonds”), with an initial issue amount of $300.0 million. On the same date, the 2030 Bonds commenced trading on Euronext Oslo Børs under the ticker symbol “NMM”.

In April 2026, Navios Partners agreed to sell a 2006-built Panamax of 75,356 dwt to an unrelated third party, for a gross sale price of $10.4 million. The sale is expected to be completed during the second quarter of 2026.

Overview

We are an international owner and operator of dry cargo and tanker vessels that was formed in August 2007 by Navios Maritime Holdings Inc under the laws of the Republic of the Marshall Islands. We have been a public company since November 2007.

As of May 15, 2026, there were outstanding 28,424,619 common units and 622,296 general partnership units. Angeliki Frangou, our Chief Executive Officer and Chairwoman beneficially owned an approximately 17.9% common interest of the total outstanding common units, consisting of 5,090,720 common units held directly or indirectly through entities affiliated with her. In addition, an entity affiliated with Angeliki Frangou beneficially owned 622,296 general partnership units, representing an approximately 2.1% ownership interest in Navios Partners based on all outstanding common units and general partnership units.

In July 2022, the Board of Directors of Navios Partners authorized a common unit repurchase program for up to $100.0 million of Navios Partners’ common units. Common unit repurchases will be made from time to time for cash in open market transactions at prevailing market prices or in privately negotiated transactions. The timing and amount of repurchases under the program will be determined by Navios Partners’ management based upon market conditions and financial and other considerations, including working capital and planned or anticipated growth opportunities. The program does not require any minimum repurchase or any specific number of common units and may be suspended or reinstated at any time in the Navios Partners’ discretion and without notice. The Board of Directors will review the program periodically. As of May 15, 2026, Navios Partners had repurchased 1,759,769 common units since the commencement of the program, for a total cost of approximately $83.6 million.

Fleet

As of May 15, 2026, Navios Partners’ fleet consisted of 65 dry bulk vessels, 51 containerships and 57 tanker vessels, including two newbuilding capesize vessels (chartered-in vessels under bareboat contracts) that are expected to be delivered in the second half of 2028 and the first quarter of 2029, seven newbuilding containerships (three 7,900 TEU containerships and four 8,850 TEU containerships) that are expected to be delivered through the first half of 2028 and 17 newbuilding tankers (four VLCC tankers, nine aframax/LR2 and four MR2 product tanker chartered-in vessels under bareboat contracts) that are expected to be delivered through 2028. The fleet excludes a VLCC tanker and a panamax vessel that have been agreed to be sold.

We generate revenues by charging our customers for the use of our vessels to transport their dry cargo commodities, containers, crude oil and/or refined petroleum products. In general, the vessels in our fleet are chartered-out under time

charters with duration of up to 12 years at inception. From time to time, we operate vessels in the spot market until the vessels have been chartered out under short-term, medium-term and long-term charters.

Our Charters

We provide seaborne shipping services under short-term, medium-term, and long-term time charters, bareboat charters and voyage charters with customers that we believe are creditworthy. For the three month periods ended March 31, 2026 and 2025, only one customer accounted for 10.0% or more of our total revenues and represented approximately 13.8% and 16.2% of our total revenues, respectively.

Our revenues are driven by the number of vessels in the fleet, the number of days during which the vessels operate and our charter hire rates, which, in turn, are affected by a number of factors, including:

Time charters are available for varying periods, ranging from a single trip (spot charter) to long-term which may be many years. In general, a long-term time charter assures the vessel owner of a consistent stream of revenue. Operating the vessel in the spot market affords the owner greater spot market opportunity, which may result in high rates when vessels are in high demand or low rates when vessel availability exceeds demand. We intend to operate our vessels in the long-term charter market. Vessel charter rates are affected by world economics, international events, weather conditions, strikes, governmental policies, supply and demand and many other factors that might be beyond our control. Please read the section entitled “Risk Factors” in our Annual Report for a discussion of certain risks inherent in our business.

We could lose a customer or the benefits of a charter if:

Under some of our time charters, either party may terminate the charter contract in the event of war in specified countries or in locations that would significantly disrupt the free trade of the vessel. Some of the time charters covering our vessels require us to return to the charterer, upon the loss of the vessel, all advances paid by the charterer but not earned by us.

Trends and Factors Affecting Our Future Results of Operations

We believe the principal factors that will affect our future results of operations are the economic, regulatory, political and governmental conditions that affect the shipping industry generally and that affect conditions in countries and markets in which our vessels engage in business. Please read “Risk Factors” in our Annual Report for a discussion of certain risks inherent in our business.

Results of Operations

Overview

The following table reflects certain key indicators of Navios Partners’ fleet performance for the three month periods ended March 31, 2026 and 2025.

FINANCIAL HIGHLIGHTS

The following table presents consolidated revenue and expense information for the three month periods ended March 31, 2026 and 2025.

Period over Period Comparisons

For the Three Month Period ended March 31, 2026 compared to the Three Month Period ended March 31, 2025

Time charter and voyage revenues: Time charter and voyage revenues for the three month period ended March 31, 2026 increased by $52.9 million, or 17.4%, to $357.0 million, as compared to $304.1 million for the same period in 2025. The increase in revenue was mainly attributable to the increase in the TCE rate. For the three month periods ended March 31, 2026 and 2025, time charter and voyage revenues were positively affected by $7.5 million and negatively affected by $2.6 million, respectively, relating to the straight-line effect of the charters with de-escalating rates. The TCE rate increased by 20.7% to $25,679 per day, as compared to $21,271 per day for the same period in 2025. The available days of the fleet decreased by 2.6% to 13,104 days for the three month period ended March 31, 2026, as compared to 13,456 days for the same period in 2025.

Time charter and voyage expenses: Time charter and voyage expenses for the three month period ended March 31, 2026 increased by $0.9 million to $30.9 million, as compared to $30.0 million for the same period in 2025. The increase was mainly attributable to a: (i) $0.8 million increase in port expenses; (ii) $0.5 million increase in commercial management fees on revenues in accordance with the management agreement; and (iii) $0.4 million increase in brokers’ commissions. The increase was partially mitigated by a $0.8 million decrease in other voyage expenses.

Vessel operating expenses: Vessel operating expenses for the three month period ended March 31, 2026 increased by $0.2 million to $95.0 million, as compared to $94.8 million for the same period in 2025. The increase was due to the change in the composition of our fleet and a 3.1% increase in the opex daily rate to $7,197, partially mitigated by a decrease of 2.8% in the opex days.

General and administrative expenses: General and administrative expenses increased by $1.8 million to $23.8 million for the three month period ended March 31, 2026, as compared to $22.0 million for the same period in 2025, mainly due to higher euro-dollar exchange rate prevailing during the first quarter of 2026.

Depreciation and amortization: Depreciation and amortization amounted to $81.7 million for the three month period ended March 31, 2026, as compared to $78.6 million for the same period in 2025. The increase of $3.1 million was attributable to a: (i) $5.9 million increase in amortization of the deferred drydock and special survey costs due to the increase in the number of vessels that underwent drydocking or special survey; (ii) $3.1 million increase in depreciation expense due to the delivery of eight vessels and the acquisition of four vessels since the first quarter of 2025; and (iii) $0.5 million increase in depreciation expense mainly due to vessel improvements. The above increase was partially mitigated by a: (i) $3.6 million decrease in depreciation expense due to the sale of 12 vessels since the first quarter of 2025; and (ii) $2.8 million decrease in amortization of favorable lease terms of intangible assets. Depreciation of vessels is calculated using an estimated useful life of 25 years for dry bulk and tanker vessels and 30 years for containerships from the date the vessel was originally delivered from the shipyard.

Amortization of unfavorable lease terms: Amortization of unfavorable lease terms amounted to $2.6 million and $2.9 million for the three month periods ended March 31, 2026 and 2025, respectively, relating to the amortization of the fair value of the time charters with unfavorable lease terms as determined at the acquisition date of Navios Maritime Containers L.P.

Gain/ (loss) on sale of vessels, net: Gain on sale of vessels, net amounted to $8.6 million for the three month period ended March 31, 2026, relating to the sale and the intention to sell our vessels. Loss on sale of vessels amounted to $5.9 million for the three month period ended March 31, 2025, relating to the sale and committed sale of our vessels.

Interest expense and finance cost, net: Interest expense and finance cost, net for the three month period ended March 31, 2026, decreased by $2.9 million to $30.6 million, as compared to $33.5 million for the same period in 2025. The decrease was mainly due to the decrease in the weighted average interest rate. The weighted average interest rate for the three month period ended March 31, 2026 decreased to 5.8% from 6.3% for the same period in 2025, while Navios Partners’ weighted average loan balance decreased to $2,195.5 million for the three month period ended March 31, 2026, as compared to $2,200.5 million for the same period in 2025.

Interest income: Interest income amounted to $3.3 million for the three month period ended March 31, 2026, as compared to $3.4 million for the same period in 2025.

Other expense, net: Other expense, net amounted to $3.1 million for the three month period ended March 31, 2026, as compared to $3.7 million for the same period in 2025, mainly due to the decrease in other miscellaneous expenses, net, partially mitigated by the increase in claims.

Net income: Net income for the three month period ended March 31, 2026 amounted to $106.3 million as compared to $41.7 million for the same period in 2025. The increase in net income of $64.6 million was due to the factors discussed above.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that have or are reasonably likely to have, a current or future material effect on our financial condition, results of operations, liquidity, capital expenditures or capital resources.

Liquidity and Capital Resources

We anticipate that our primary sources of funds for our short-term liquidity needs will consist of cash flows from operations, our equity offerings, proceeds from asset sales, long-term bank borrowings and other debt raisings. In addition to distributions on our units and common unit repurchase program, our primary short-term liquidity needs are to fund general working capital requirements, cash reserve requirements including those under our credit facilities and debt service, while our long-term liquidity needs primarily relate to expansion and investment capital expenditures and maintenance capital expenditures and debt repayment. As of March 31, 2026, Navios Partners’ current assets totaled $533.1 million, while current liabilities totaled $367.5 million, resulting in a positive working capital position of $165.6 million. Navios Partners’ cash forecast indicates that it will generate sufficient cash through its contracted revenue as of May 15, 2026, of $4.1 billion, cash proceeds from the sale of vessels (see Note 4 – Vessels, net and Note 15 – Subsequent events to the unaudited condensed consolidated financial statements included elsewhere in this report) and undrawn amounts available under credit facilities to make the required principal and interest payments on its indebtedness, to make payments for capital expenditures and provide for the normal working capital requirements of the business for a period of at least 12 months from the date of issuance of our unaudited condensed consolidated financial statements.

Generally, our long-term sources of funds for acquisitions and expansion and investment capital expenditures derive from cash from operations, long-term bank borrowings and other debt or equity financings. We cannot assure you that we will be able to secure adequate financing or to obtain additional funds on favorable terms, to meet our liquidity needs.

Cash deposits and cash equivalents in excess of amounts covered by government-provided insurance are exposed to loss in the event of non-performance by financial institutions. Navios Partners does maintain cash deposits and cash equivalents in excess of government-provided insurance limits. Navios Partners also mitigates exposure to credit risk by dealing with a diversified group of major financial institutions.

Navios Partners may use funds to repurchase its outstanding common units and/or repay indebtedness from time to time. Repurchases may be made in the open market, or through privately negotiated transactions or otherwise, in compliance with applicable laws, rules and regulations, at prices and on terms Navios Partners deems appropriate and subject to its cash requirements for other purposes, compliance with the covenants under Navios Partners’ credit facilities, bonds and other financing agreements, and other factors management deems relevant.

In July 2022, the Board of Directors of Navios Partners authorized a common unit repurchase program for up to $100.0 million of Navios Partners’ common units. Common unit repurchases will be made from time to time for cash in open market transactions at prevailing market prices or in privately negotiated transactions. The timing and amount of repurchases under the program will be determined by Navios Partners’ management based upon market conditions and financial and other considerations, including working capital and planned or anticipated growth opportunities. The program does not require any minimum repurchase or any specific number of common units and may be suspended or reinstated at any time in the Navios Partners’ discretion and without notice. The Board of Directors will review the program periodically. As of May 15, 2026, Navios Partners had repurchased 1,759,769 common units since the commencement of the program, for a total cost of approximately $83.6 million.

The following table presents cash flow information derived from the unaudited condensed Consolidated Statements of Cash Flows of Navios Partners for the three month periods ended March 31, 2026 and 2025.

Net cash provided by operating activities for the three month period ended March 31, 2026 as compared to the net cash provided by operating activities for the three month period ended March 31, 2025

Net cash provided by operating activities decreased by $30.0 million to $126.6 million for the three month period ended March 31, 2026, as compared to $156.6 million for the same period in 2025. In determining net cash provided by operating activities, net income is adjusted for the effects of certain non-cash items as discussed below.

The aggregate adjustments to reconcile net income to net cash provided by operating activities were $57.5 million of non-cash positive net adjustments for the three month period ended March 31, 2026, which consisted mainly of the following adjustments: (i) $81.7 million depreciation and amortization; and (ii) $1.8 million amortization and write-off of deferred finance costs. These adjustments were partially mitigated by: (i) $14.6 million other non-cash adjustments; (ii) $8.6 million gain on sale of vessels, net; (iii) $2.6 million amortization of unfavorable lease terms; and (iv) $0.2 million amortization of operating lease assets/ liabilities.

The net cash outflow resulting from the change in operating assets and liabilities of $37.2 million for the three month period ended March 31, 2026 resulted from: (i) $19.8 million in payments for drydock and special survey costs; (ii) a $12.4 million increase in accounts receivable; (iii) a $10.3 million decrease in deferred revenue; (iv) a $4.0 million decrease in accounts payable; and (v) a $0.7 million decrease in amounts due to related parties. This was partially mitigated by a: (i) $7.9 million increase in accrued expenses; and (ii) $2.1 million decrease in prepaid expenses and other current assets.

The aggregate adjustments to reconcile net income to net cash provided by operating activities were $84.4 million of non-cash positive net adjustments for the three month period ended March 31, 2025, which consisted mainly of the following adjustments: (i) $78.6 million depreciation and amortization; (ii) $5.9 million loss on sale of vessels; (iii) $1.7 million amortization and write-off of deferred finance costs; and (iv) $1.2 million other non-cash adjustments. These adjustments were partially mitigated by: (i) $2.9 million amortization of unfavorable lease terms; and (ii) $0.1 million amortization of operating lease assets/ liabilities.

The net cash inflow resulting from the change in operating assets and liabilities of $30.5 million for the three month period ended March 31, 2025 resulted from a: (i) $35.2 million decrease in amounts due from related parties; (ii) $22.8 million increase in amounts due to related parties; (iii) $4.8 million increase in accrued expenses; (iv) $2.5 million decrease in prepaid expenses and other current assets; (v) $1.2 million decrease in accounts receivable; and (vi) $0.7 million increase in deferred revenue. This was partially mitigated by: (i) $31.4 million in payments for drydock and special survey costs; and (ii) a $5.3 million decrease in accounts payable.

Net cash used in investing activities for the three month period ended March 31, 2026 as compared to the net cash used in investing activities for the three month period ended March 31, 2025

Net cash used in investing activities for the three month period ended March 31, 2026 amounted to $162.4 million as compared to $134.1 million net cash used in investing activities for the same period in 2025.

Net cash used in investing activities of $162.4 million for the three month period ended March 31, 2026 was mainly due to: (i) $119.6 million related to vessel acquisitions and additions; and (ii) $72.7 million related to deposits for the acquisition/ option to acquire vessels and capitalized expenses. This was partially mitigated by: (i) $29.4 million of proceeds related to the sale of one vessel; and (ii) a $0.5 million decrease in time deposits with original maturities greater than three months.

Net cash used in investing activities of $134.1 million for the three month period ended March 31, 2025 was mainly due to: (i) $98.2 million related to vessel acquisitions and additions; (ii) $34.3 million related to deposits for the acquisition/ option to acquire vessels and capitalized expenses; and (iii) a $9.1 million increase in time deposits with original maturities greater than three months. This was partially mitigated by $7.5 million of proceeds related to the sale of one vessel.

Net cash provided by financing activities for the three month period ended March 31, 2026 as compared to net cash used in financing activities for the three month period ended March 31, 2025

Net cash provided by financing activities increased by $44.6 million to $44.0 million inflow for the three month period ended March 31, 2026, as compared to $0.6 million outflow for the same period in 2025.

Net cash provided by financing activities of $44.0 million for the three month period ended March 31, 2026 was mainly due to $175.2 million of proceeds from the new credit facilities and sale and leaseback agreements. This was partially mitigated by: (i) $118.8 million repayments of long-term debt, finance lease and financial liabilities; (ii) $10.2 million related to the acquisition of treasury units; (iii) $1.5 million of payments for cash distributions; and (iv) $0.7 million payments of deferred finance costs related to the credit facilities, bonds and financial liabilities.

Net cash used in financing activities of $0.6 million for the three month period ended March 31, 2025 was mainly due to: (i) $77.6 million repayments of long-term debt, finance lease and financial liabilities; (ii) $10.0 million related to the acquisition of treasury units; (iii) $1.6 million payments of deferred finance costs related to the new credit facilities and financial liabilities; and (iv) $1.5 million of payments for cash distributions. This was partially mitigated by $90.1 million of proceeds from the new credit facility and sale and leaseback agreement.

Reconciliation of EBITDA and Adjusted EBITDA to Net Cash from Operating Activities, EBITDA and Operating Surplus

(1) EBITDA and Adjusted EBITDA

EBITDA represents net income before interest and finance costs, depreciation and amortization and income taxes. Adjusted EBITDA represents EBITDA excluding certain items, as described in the table above. Navios Partners uses Adjusted EBITDA as a liquidity measure and reconciles EBITDA and Adjusted EBITDA to net cash provided by operating activities, the most comparable U.S. GAAP liquidity measure. EBITDA in this document is calculated as follows: net cash provided by operating activities adding back, when applicable and as the case may be, the effect of: (i) net increase/ (decrease) in operating assets; (ii) net decrease/ (increase) in operating liabilities; (iii) net interest cost; (iv) amortization and write-off of deferred finance costs; (v) amortization of operating lease assets/ liabilities; (vi) other non-cash adjustments; and (vii) gain/ (loss) on sale of vessels, net. Navios Partners believes that EBITDA and Adjusted EBITDA are each the basis upon which liquidity can be assessed and present useful information to investors regarding Navios Partners’ ability to service and/or incur indebtedness, pay capital expenditures, meet working capital requirements and make cash distributions. Navios Partners also believes that EBITDA and Adjusted EBITDA are used: (i) by potential lenders to evaluate potential transactions; (ii) to evaluate and price potential acquisition candidates; and (iii) by securities analysts, investors and other interested parties in the evaluation of companies in our industry.

Each of EBITDA and Adjusted EBITDA have limitations as an analytical tool, and should not be considered in isolation or as a substitute for the analysis of Navios Partners’ results as reported under U.S. GAAP. Some of these limitations are: (i) EBITDA and Adjusted EBITDA do not reflect changes in, or cash requirements for, working capital needs; and (ii) although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future. EBITDA and Adjusted EBITDA do not reflect any cash requirements for such capital expenditures. Because of these limitations, EBITDA and Adjusted EBITDA should not be considered as a principal indicator of Navios Partners’ performance. Furthermore, our calculation of EBITDA and Adjusted EBITDA may not be comparable to that reported by other companies due to differences in methods of calculation.

EBITDA for the three month periods ended March 31, 2026 and 2025 was affected by the item described in the table above. Excluding this item, Adjusted EBITDA increased by $50.6 million to $204.1 million for the three month period ended March 31, 2026, as compared to $153.5 million for the same period in 2025. The increase in Adjusted EBITDA was due to a: (i) $52.9 million increase in time charter and voyage revenues; and (ii) $0.6 million decrease in other expense, net. The above increase was partially mitigated by a: (i) $1.8 million increase in general and administrative expenses mainly due to higher euro-dollar exchange rate prevailing during the first quarter of 2026; (ii) $0.9 million increase in time charter and voyage expenses; and (iii) $0.2 million increase in vessel operating expenses as a result of the change in the composition of our fleet and a 3.1% increase in the opex daily rate to $7,197, partially mitigated by a decrease of 2.8% in the opex days.

(2) Operating Surplus

Navios Partners generated Operating Surplus for the three month period ended March 31, 2026 of $100.6 million, as compared to $47.1 million for the three month period ended March 31, 2025. Operating Surplus is a non-GAAP financial measure used by certain investors to assist in evaluating a partnership’s ability to make quarterly cash distributions (See “Reconciliation of EBITDA and Adjusted EBITDA to Net Cash from Operating Activities, EBITDA and Operating Surplus” contained herein).

Operating Surplus represents net income adjusted for depreciation and amortization expense, non-cash interest expense, non-cash interest income, estimated maintenance and replacement capital expenditures and one-off items. Maintenance and replacement capital expenditures are those capital expenditures required to maintain over the long term the operating capacity of, or the revenue generated by, Navios Partners’ capital assets.

Operating Surplus is a quantitative measure used in the publicly-traded partnership investment community to assist in evaluating a partnership’s ability to make quarterly cash distributions. Operating Surplus is not required by accounting principles generally accepted in the United States and should not be considered a substitute for net income, cash flow from operating activities and other operations or cash flow statement data prepared in accordance with accounting principles generally accepted in the United States or as a measure of profitability or liquidity.

Capital Expenditures

Navios Partners finances its capital expenditures with cash flows from operations, equity offerings, proceeds from asset sales, long-term bank borrowings and other debt raisings. Capital expenditures for each of the three month periods ended March 31, 2026 and 2025 amounted to $192.3 million and $132.5 million, respectively.

Maintenance for our vessels and expenses related to drydocking costs are reimbursed at cost by Navios Partners to Navios Shipmanagement Inc. and its affiliates, which are entities affiliated with the Company’s Chairwoman and Chief Executive Officer, under the management agreement. For more information, please read Note 12 – Transactions with related parties and affiliates to the unaudited condensed consolidated financial statements, included elsewhere in this report.

Maintenance and Replacement Capital Expenditures Reserve

The reserves for estimated maintenance and replacement capital expenditures for the three month period ended March 31, 2026 were $78.3 million. We estimate that our annual replacement reserve for the year ending December 31, 2026 will be approximately $304.6 million, for replacing our vessels at the end of their useful lives. The reserves for estimated maintenance and replacement capital expenditures for the three month period ended March 31, 2025 were $76.9 million.

The amount for estimated replacement capital expenditures attributable to future vessel replacement was based on the following assumptions: (i) current market price to purchase a five-year-old vessel of similar size and specifications; (ii) a 25-year useful life for dry bulk and tanker vessels and a 30-year useful life for containerships; and (iii) a relative net investment rate.

The amount for estimated maintenance capital expenditures attributable to future vessel drydocking and special survey was based on certain assumptions including the remaining useful life of the owned vessels of our fleet, market costs of drydocking and special survey and a relative net investment rate.

Our board of directors, with the approval of the Conflicts Committee, may determine that one or more of our assumptions should be revised, which could cause our board of directors to increase or decrease the amount of estimated maintenance and replacement capital expenditures. The actual cost of replacing the vessels in our fleet will depend on a number of factors, including prevailing market conditions, charter hire rates and the availability and cost of financing at the time of replacement. We may elect to finance some or all of our maintenance and replacement capital expenditures through the issuance of additional common units, which could be dilutive to existing unitholders.

Limitations on Cash Distributions and Our Ability to Change Our Cash Distribution Policy

There is no guarantee that unitholders will receive quarterly distributions from us on the common units on any quarter.

Our ability to make distributions to our unitholders depends on the performance of our subsidiaries and their ability to distribute funds to us. The ability of our subsidiaries to make distributions to us may be restricted by, among other things,

the provisions of existing and future indebtedness, applicable partnership and limited liability company laws and other laws and regulations.

See Note 13 – Cash distributions and earnings per unit to the unaudited condensed consolidated financial statements included elsewhere in this report.

Quantitative and Qualitative Disclosures about Market Risks

Foreign Exchange Risk

Our functional and reporting currency is the U.S. dollar. We engage in worldwide commerce with a variety of entities. Although our operations may expose us to certain levels of foreign currency risk, our transactions are predominantly U.S. dollar denominated. Transactions in currencies other than the U.S. dollar are translated at the exchange rate in effect at the date of each transaction. Differences in exchange rates are recognized during the period between the date a transaction denominated in a foreign currency is consummated and the date on which it is either settled or translated.

Interest Rate Risk

We finance a portion of our vessel investments through long-term floating-rate credit facilities and financial liabilities linked to Secured Overnight Financing Rate (“SOFR”). As a result, increases in prevailing interest rates would increase our cost of capital.

Borrowings under certain of our credit facilities and financial liabilities bear interest at a rate based on a premium over SOFR. Therefore, we are exposed to the risk that our interest expense may increase if interest rates rise. For the three month periods ended March 31, 2026 and 2025, we paid interest on our outstanding debt at a weighted average interest rate of 5.8% and 6.3%, respectively. A 1% increase in SOFR would have increased our interest expense for the three month periods ended March 31, 2026 and 2025 by $3.7 million and $4.6 million, respectively.

Concentration of Credit Risk

Financial instruments, which potentially subject us to significant concentrations of credit risk, consist principally of cash, other investments and trade accounts receivable. We closely monitor our exposure to customers for credit risk. We have policies in place to ensure that we trade with customers with an appropriate credit history.

For the three month periods ended March 31, 2026 and 2025, only one customer accounted for 10.0% or more of our total revenues and represented approximately 13.8% and 16.2% of our total revenues, respectively.

If we lose a charter, we may be unable to re-deploy the related vessel on terms as favorable to us due to the long-term nature of most charters and the cyclical nature of the industry or we may be forced to charter the vessel on the spot market at then market rates which may be less favorable than the charter that has been terminated. If we are unable to re-deploy a vessel for which the charter has been terminated, we will not receive any revenues from that vessel, but we may be required to pay expenses necessary to maintain the vessel in proper operating condition. If we lose a vessel, any replacement or newbuilding would not generate revenues during its construction or acquisition period, and we may be unable to charter any replacement vessel on terms as favorable to us as those of the terminated charter.

Even if we successfully charter our vessels in the future, our charterers may go bankrupt or fail to perform their obligations under the charter agreements, they may delay payments or suspend payments altogether, they may terminate the charter agreements prior to the agreed-upon expiration date or they may attempt to renegotiate the terms of the charters. The permanent loss of a customer, time charter or vessel, or a decline in payments under our charters, could have a material adverse effect on our business, results of operations and financial condition and our ability to make cash distributions or payments in the event we are unable to replace such customer, time charter or vessel.
