Other Highlights and Developments

Operational Update

Total operating revenue was $146.7 million for the three months ended June 30, 2024, compared to $135.3 million for the three months ended June 30, 2023.

Average daily time charter equivalent2 ("TCE") across the fleet increased to $29,550 for the three months ended June 30, 2024, compared to $27,241 for the three months ended June 30, 2023.

Utilization across the fleet increased to 93.4% for three months ended June 30, 2024 compared to 89.3% for three months ended March 31,2024 and 89.0% for the three months ended June 30, 2023. The increase in utilization was primarily driven by improved market and LPG trading conditions for the semi-refrigerated vessels.

During the three months ended June 30, 2024 the arbitrage between the price of ethylene in the U.S. compared to the price of ethylene in the rest of the world increased resulting in higher demand for ethylene to be shipped from the U.S.. Although the Panama Canal suffered from a reduction in available transits during the three months ended December 31, 2023 and March 31, 2024 due to drought conditions that reduced water levels in the man-made Gatún Lake which holds the water supply that operates the canal, the number of vessel transits returned back close to historical levels in the second quarter of 2024. This resulted in shorter sea passages, particularly for handysize ethylene-capable vessels as they were able to proceed via the Panama Canal rather than undertake the longer voyage via the Cape of Good Hope.

For the three months ended June 30, 2024, we had on average 32 vessels engaged under time charters, 15 vessels on spot voyage charters and contracts of affreightment ("CoA") and nine vessels were operated in the independently managed Unigas Pool. For the 12-month period commencing July 1, 2024, we have 43% of our available days covered under time charter with fixed earnings. In this period our midsize and fully refrigerated vessels are almost exclusively employed on time charters, our semi-refrigerated vessels are employed under time charters and spot voyage charters, and most of our ethylene-capable vessels are expected to be employed on the spot voyage market.

The average handysize 12-month forward looking market assessment for semi-refrigerated and fully-refrigerated vessels for the second quarter of 2024 decreased by $34,000 and $50,000 per calendar month (“pcm”), to an average of $928,000 pcm and $837,000 pcm respectively, compared to the first quarter of 2024. The handysize ethylene 12-month forward looking market assessment decreased by $60,000 pcm or 5% from $1,257,000 pcm to $1,198,000 pcm in the second quarter of 2024 compared to the first quarter of 2024.

Ethylene cargo spot rates are expected to decrease in the three months ended September 30, 2024 due to a narrowing ethylene arbitrage between the U.S. and the rest of the world. The decrease is due to a strengthening U.S. domestic ethylene price caused by production disruptions arising from Hurricane Beryl, as well as unplanned maintenance shutdowns at several production plants, however we expect some ethylene cargoes to be substituted by ethane exports due to an increase in the competitiveness of U.S. ethane.

Ethylene Export Terminal

We own a 50% share in an ethylene export marine terminal at Morgan’s Point, Texas (the “Ethylene Export Terminal”) through a joint venture (the "Export Terminal Joint Venture"). The Ethylene Export Terminal throughput for the three months ended June 30, 2024, was 230,857 metric tons, compared to 277,582 metric tons for the three months ended June 30, 2023. Our share of the results of our equity investment in the Ethylene Export Terminal was $4.7 million for the three months ended June 30, 2024, compared to $6.0 million for the three months ended June 30, 2023.

We, together with Enterprise Products Partners L.P, our joint venture partner, have agreed to invest in an expansion of the Ethylene Export Terminal (the “Terminal Expansion Project”). The expansion is expected to increase the export capacity from approximately one million tons of ethylene per annum to at least 1.55 million tons per annum. All major project equipment has been delivered with support infrastructure and new pipes being assembled, with operations scheduled to commence in late December 2024. The first new multi-year offtake contract related to the expansion has been signed, and another customer has agreed to extend and upsize its current offtake with the associated contract expected to be signed during the third quarter of 2024. We expect that additional capacity will be contracted during the remainder of the construction phase.

The total capital contributions required from us to the Export Terminal Joint Venture for the Terminal Expansion Project are expected to be approximately $130 million. The Company expects to finance this using existing cash resources, distributions from the Export Terminal Joint Venture during the course of the expansion and additional debt. Of the expected total of $130 million, $59 million has been contributed as of June 30, 2024, with $16 million of that contributed during the three months ended June 30, 2024.

Bluestreak CO2

On July 24, 2024 Bluestreak CO2 Limited, the 50/50 joint venture relating to the previously announced non-binding memorandum of understanding between Navigator Gas and Bumi Armada Berhad (“Bumi Armada”) announced that it has entered into a memorandum of understanding (the “MoU”) with international energy company Uniper (UK) Limited (“Uniper”). Under the MOU the parties have agreed to collaborate to explore the feasibility of implementing a jetty-moored floating liquid CO2 storage facility and liquid CO2 carrier solution, for the export of CO2 from Uniper’s proposed Grain Carbon Capture project on the Isle of Grain, United Kingdom.

The parties to the MoU anticipate that Bluestreak CO2, by leveraging the expertise and experience of Navigator Gas and Bumi Armada, could design, and ultimately implement a comprehensive CO2 value chain. The value chain is expected to be comprised of liquid CO2 shuttle tankers capable of

loading from and delivering to either a floating carbon storage unit or a floating carbon storage and injection unit. The complete value chain is expected to transport liquid CO2 safely and reliably, and provide buffer storage capability. The CO2 is intended to be subsequently injected into offshore storage aquifers and/or depleted oil and gas reservoirs in a controlled manner, with surveillance and management of the permanent storage location.

Bumi Armada and Navigator Gas anticipate entering into definitive documentation for the Bluestreak CO2 joint venture by the end of the fourth quarter of 2024. The joint venture is subject to the execution of such definitive documentation, approvals by the respective boards of directors of Navigator Gas and Bumi Armada, applicable regulatory approvals and other customary closing conditions. There can be no assurance that definitive documentation for the Bluestreak CO2 joint venture transaction will be executed or that the joint venture will be completed on the terms or the timing anticipated, or at all. There also can be no assurance that the value chain for shipment, storage and injection of CO2 will be designed and implemented as anticipated or at all.

Return of Capital Policy

The Company’s current Return of Capital policy, which is subject to operating needs and other circumstances, is based on paying out quarterly cash dividends of $0.05 per share of common stock and returning additional capital in the form of additional cash dividends and/or Share Repurchases (as defined below), such that the two elements combined equal at least 25% of net income for the applicable quarter.

As part of the Return of Capital policy, we expect to repurchase the Company’s common stock (the “Share Repurchases”) and any such Share Repurchases will be made via open market transactions, privately negotiated transactions or any other method permitted under U.S. securities laws and the rules of the U.S. Securities and Exchange Commission.

Declarations of any dividends in the future, and the amount of any such dividends, are subject to the discretion of the Company’s Board. The Return of Capital policy does not oblige the Company to pay any dividends or repurchase any of its shares in the future and it may be suspended, discontinued or modified by the Company at any time, for any reason. Further, the timing of any Share Repurchases under the Return of Capital policy will be determined by the Company’s management and will depend on market conditions, legal requirements, stock price, and other factors.

Ten08 Clean Ammonia Investment

On August 8, 2024, the Company announced a $2.5 million co-investment alongside lead investor Attis Clean Energy (“Attis”) in the clean ammonia developer Ten08 Energy LLC (“Ten08”).

Ten08 is developing an industrial-scale hybrid blue and green ammonia production export facility on the Gulf Coast of Texas with the goal of producing the most competitively priced ammonia molecule to help decarbonize the power, shipping, fertilizer, and chemicals industries. The first phase, comprising 1.4 million metric tonnes per year of ultra-low carbon ammonia production, is expected to commence operations in late 2029 or early 2030.

In return for our initial investment of $2.5 million we will also receive an option to make a larger investment of up to $100 million at the time of final investment decision of the production facility. This larger investment would take the form of preferred equity towards construction of an export terminal and associated export infrastructure, with potential further investments in subsequent expansions. We expect to pay $1.25 million in August 2024 and a further $1.25 million in late 2024 or early 2025.

August 2024 Senior Secured Term Loan and Revolving Credit Facility

On August 9, 2024, the Company entered into a Senior Secured Term Loan and Revolving Credit Facility (the “August 2024 Facility”) with Crédit Agricole Corporate and Investment Bank, ING Bank N.V., and Skandinaviska Enskilda Banken AB (Publ), to refinance its March 2019 secured term loan that was due to mature in March 2025, to fund the repurchase of the Navigator Aurora pursuant to the Company’s existing October 2019 sale and leaseback arrangement related to that vessel which, based on a termination notice we issued to the lessor in May 2024, will terminate in October 2024, and for general corporate and working capital purposes. The August 2024 Facility has a term of six years maturing in August 2030, is for a maximum principal amount of $147.6 million, decreases quarterly followed by a final balloon payment in August 2030 of $63.9 million, and bears interest at a rate of Term SOFR plus 190 basis points, which margin includes a 5-basis point sustainability-linked element.

Operating Revenues. Operating revenues, net of address commissions, was $131.6 million for the three months ended June 30, 2024, an increase of $9.5 million or 7.8% compared to $122.1 million for the three months ended June 30, 2023. This increase was primarily due to:

• an increase of approximately $8.5 million attributable to an increase in average monthly time charter equivalent rates, which increased to an average of approximately $29,550 per vessel per day ($898,823 per vessel per calendar month) for the three months ended June 30, 2024, compared to an average of approximately $27,241 per vessel per day ($828,582 per vessel per calendar month) for the three months ended June 30, 2023;

• an increase of approximately $5.4 million attributable to an increase in fleet utilization, which increased to 93.4% for the three months ended June 30, 2024, compared to 89.0% for the three months ended June 30, 2023;

• a decrease of approximately $3.0 million or 2.9%, attributable to a 122 day decrease in vessel available days for the three months ended June 30, 2024, compared to the three months ended June 30, 2023. This decrease was in part a result of increased drydocking during the three months ended June 30, 2024, compared to the three months ended June 30, 2023; and

• a decrease of approximately $1.5 million primarily attributable to a decrease in invoiced pass through voyage expense for the three months ended June 30, 2024, compared to the three months ended June 30, 2023.

The following table presents selected operating data for the three months ended June 30, 2024 and 2023, which we believe is useful in understanding the basis of movements in our operating revenues.

** Non-GAAP Financial Measure—Time charter equivalent: TCE is a measure of the average daily revenue performance of a vessel. TCE is not calculated in accordance with U.S. GAAP. For all charters, we calculate TCE by dividing total operating revenues (excluding collaborative arrangements and revenues from the Unigas Pool), less any voyage expenses (excluding collaborative arrangements), by the number of earning days for the relevant period. TCE excludes the effects of the collaborative arrangements as earning days and fleet utilization, on which TCE is based, is calculated only in relation to our owned vessels. Under a time charter, the charterer pays substantially all of the vessel's voyage related expenses, whereas for voyage charters, also known as spot market charters, we pay all voyage expenses. TCE is a shipping industry performance measure used primarily to compare period-to-period changes in a company’s performance despite changes in the mix of charter types (i.e., voyage charters, time charters and contracts of affreightment) under which the vessels may be employed. We include average daily TCE, as we believe it provides additional meaningful information in conjunction with net operating revenues. Our calculation of TCE may not be comparable to that reported by other companies.

Operating revenues - Luna Pool collaborative arrangements was $nil for the three months ended June 30, 2024, compared to $0.2 million for the three months ended June 30, 2023, and represented our share of pool net revenues generated by the other participant’s vessels in the pool, prior to the acquisition of the vessels by Navigator Greater Bay Joint Venture. This decrease was a result of the Company no longer accounting for any of the pool vessels’ earnings under the Luna Pool collaborative arrangement following the acquisition of the final vessel Navigator Vega on April 13, 2023.

Brokerage Commissions. Brokerage commissions, which typically vary between 1.25% and 2.5% of operating revenues, increased by $0.2 million or 7.7% to $1.9 million for the three months ended June 30, 2024, from $1.7 million for the three months ended June 30, 2023, primarily due to an increase in operating revenue on which brokerage commission is based.

Voyage Expenses. Voyage expenses decreased by $1.5 million or 8.0% to $17.1 million for the three months ended June 30, 2024, from $18.6 million for the three months ended June 30, 2023. These voyage expenses are pass through costs, corresponding to a decrease in operating revenues of the same amount.

Voyage Expenses – Luna Pool Collaborative Arrangements. Voyage expenses – Luna Pool collaborative arrangements were $nil for the three months ended June 30, 2024, compared to $0.5 million for the three months ended June 30, 2023. These Voyage expenses – Luna Pool collaborative arrangements represent the other participant’s share of pool net revenues generated by our vessels in the pool, prior to the acquisition of the vessels by Navigator Greater Bay Joint Venture. This decrease was a result of the Company no longer accounting for any of the pool vessels’ earnings under the Luna Pool collaborative arrangement following the acquisition of the final vessel Navigator Vega on April 13, 2023.

Vessel Operating Expenses. Vessel operating expenses increased by $0.5 million or 1.2% to $43.5 million for the three months ended June 30, 2024, from $43.0 million for the three months ended June 30, 2023. Average daily vessel operating expenses increased by $35 per vessel per day, or 0.4%, to $8,535 vessel per day for the three months ended June 30, 2024, compared to $8,500 per vessel per day for the three months ended June 30, 2023.

Depreciation and Amortization. Depreciation and amortization increased by $1.2 million to $33.3 million for the three months ended June 30, 2024 compared to $32.2 million for the three months ended June 30, 2023. Depreciation and amortization included amortization of capitalized drydocking costs of $5.6 million and $4.6 million for the three months ended June 30, 2024 and 2023, respectively.

General and Administrative Costs. General and administrative costs increased by $3.1 million or 37.7% to $11.3 million for the three months ended June 30, 2024, from $8.2 million for the three months ended June 30, 2023.The increase is in part due to non-recurring costs related to the public offering of a total of 7.0 million common shares by BW Group incurred in the three months ended June 30, 2024.

Non-Operating Results

Unrealized (Loss)/ Gains on Non-Designated Derivative Instruments. The unrealized loss of $1.6 million on non-designated derivative instruments for the three months ended June 30, 2024, relates to fair value losses on interest rate swaps associated with a number of our secured term loan and revolving credit facilities, as a result of a decrease in forward Secured Overnight Financing Rate (“SOFR”) interest rates, compared to an unrealized gain of $3.2 million for the three months ended June 30, 2023.

Interest Expense. Interest expense decreased by $0.8 million, or 4.9%, to $16.2 million for the three months ended June 30, 2024, from $17.0 million for the three months ended June 30, 2023. This is primarily a result of increases in U.S dollar SOFR rates, offset by a reduction in debt due to scheduled quarterly repayments and repayments made against our available revolving credit facilities.

Income Taxes. Income taxes relate to taxes on our subsidiaries and businesses incorporated around the world including those incorporated in the United States of America. Income taxes were $1.2 million for the three months ended June 30, 2024, compared to $2.0 million for the three months ended June 30, 2023, primarily related to movement in current tax and a deferred tax in relation to our equity investment in the Ethylene Export Terminal.

Share of Result of Equity Method Investments. The share of the result of the Company’s 50% ownership in the Export Terminal Joint Venture was income of $4.7 million for the three months ended June 30, 2024, compared to income of $6.0 million for the three months ended June 30, 2023. The decrease was primarily due to lower volumes exported through the Ethylene Export Terminal in May 2024, being 230,857 tons for the three months ended June 30, 2024, compared to 277,582 tons for the three months ended June 30, 2023.

Non-Controlling Interests. The Company entered into a sale and leaseback arrangement in November 2019 with a wholly-owned special purpose vehicle of a financial institution (“Lessor SPV”). Although we do not hold any equity investments in this Lessor SPV, we have determined that we are the primary beneficiary of this entity and accordingly, we are required to consolidate this variable interest entity ("VIE") into our financial results. The net income attributable to the Lessor SPV was $0.7 million for the three months ended June 30, 2024, and $0.4 million for the three months ended June 30, 2023.

Navigator Greater Bay Joint Venture

In September 2022, the Company entered into the Navigator Greater Bay Joint Venture to acquire five ethylene vessels, Navigator Luna, Navigator Solar, Navigator Castor, Navigator Equator, and Navigator Vega. The joint venture is owned 60% by the Company and 40% by Greater Bay Gas Co Ltd., ("Greater Bay"). The Navigator Greater Bay Joint Venture is accounted for as a consolidated subsidiary in our consolidated financial statements, with the 40% owned by Greater Bay accounted for as a non-controlling interest. $2.9 million is presented as part of the non-controlling interest in our financial results to Greater Bay for the three months ended June 30, 2024, compared to $0.6 million for the three months ended June 30, 2023.

Operating Revenues. Operating revenues, net of address commissions, was $252.6 million for the six months ended June 30, 2024, an increase of $13.9 million or 5.8% compared to $238.7 million for the six months ended June 30, 2023. This increase was principally due to:

•an increase in operating revenues of approximately $19.6 million attributable to an increase in average monthly time charter equivalent rates, which increased to an average of approximately $28,953 per vessel per day ($880,647 per vessel per calendar month) for the six months ended June 30, 2024, compared to an average of approximately $26,418 per vessel per day ($705,911 per vessel per calendar month) for the six months ended June 30, 2023;

•a decrease in operating revenues of approximately $2.8 million attributable to a decrease in fleet utilization, which declined to 91.4% for the six months ended June 30, 2024, compared to 92.6% for the six months ended June 30, 2023;

•an increase in operating revenues of approximately $1.6 million or 0.8% attributable to a 67 day increase in vessel available days for the six months ended June 30, 2024, compared to the six months ended June 30, 2023.

•a decrease in operating revenues of approximately $4.5 million primarily attributable to a decrease in pass through voyage costs for the six months ended June 30, 2024, compared to the six months ended June 30, 2023.

The following table presents selected operating data for the six months ended June 30, 2024 and 2023, which we believe are useful in understanding the basis for movement in our operating revenues.

***Operating revenue and voyage expenses excluding Luna Pool Collaborative Arrangements and our nine owned vessels in the independently managed Unigas Pool.

Operating Revenues – Unigas Pool. Operating revenues – Unigas Pool was $28.2 million for the six months ended June 30, 2024, an increase of 11.7% compared to $25.3 million for the six months ended June 30, 2023 and represents our share of the revenues earned from our nine vessels operating within the Unigas Pool, based on agreed pool points.

Operating Revenues – Luna Pool Collaborative Arrangements. Luna Pool earnings were aggregated and then allocated (after deducting pool overheads and managers' fees) to the pool participants in accordance with the Pooling Agreement. Operating revenues - Luna Pool collaborative arrangements was $nil for the six months ended June 30, 2024, compared to $7.4 million for the six months ended June 30, 2023 and represented our share of pool net revenues generated by the other participant’s vessels in the pool, prior to the acquisition of the vessels by Navigator Greater Bay Joint Venture. This decrease was a result of the Company no longer accounting for any of the pool vessels’ earnings under the Luna Pool collaborative arrangement following the acquisition of the final vessel Navigator Vega on April 13, 2023.

Brokerage Commissions. Brokerage commissions, which typically vary between 1.25% and 2.5% of operating revenues, increased by $0.1 million to $3.5 million for the six months ended June 30, 2024 an increase of 1.9% compared to $3.4 million for the six months ended June 30, 2023, primarily due to an increase in operating revenues on which brokerage commissions are based.

Voyage Expenses. Voyage expenses decreased by $4.5 million or 12.6% to $31.3 million for the six months ended June 30, 2024, from $35.8 million for the six months ended June 30, 2023. These voyage expenses are pass through costs, corresponding to a decrease in operating revenues of the same amount.

Voyage Expenses – Luna Pool Collaborative Arrangements. Voyage expenses – Luna Pool collaborative arrangements were $nil for the six months ended June 30, 2024, compared to $5.5 million for the six months ended June 30, 2023. These Voyage expenses – Luna Pool collaborative arrangements represent the other participant’s share of pool net revenues generated by our vessels in the pool, prior to the acquisition of the vessels by Navigator Greater Bay Joint Venture. This decrease was primarily a result of the arrangements ending with the acquisition of the final vessel Navigator Vega on April 13, 2023.

Vessel Operating Expenses. Vessel operating expenses increased by $0.9 million or 1.1% to $85.6 million for the six months ended June 30, 2024, from $84.7 million for the six months ended June 30, 2023. Average daily vessel operating expenses increased by $93 per vessel per day, or 1.1%, to $8,493 per vessel per day for the six months ended June 30, 2024, compared to $8,400 per vessel per day for the six months ended June 30, 2023.

Depreciation and Amortization. Depreciation and amortization increased by $2.8 million to $66.8 million for the six months ended June 30, 2024, from $64.0 million for the six months ended June 30, 2023. Depreciation and amortization included amortization of capitalized drydocking costs of $11.2 million and 9.0 million for the six months ended June 30, 2024 and 2023, respectively.

General and Administrative Costs. General and administrative costs increased by $2.8 million or 18.8% to $17.8 million for the six months ended June 30, 2024, from $15.0 million for the six months ended June 30, 2023. The increase is in part due to non-recurring costs related to the public offering of a total of 7.0 million common shares by BW Group incurred in the six months ended June 30, 2024.

Non-operating Results

Unrealized Loss on Non-designated Derivative Instruments. The unrealized loss of $2.0 million on non-designated derivative instruments for the six months ended June 30, 2024 relates to a fair value loss on interest rate swaps across a number of our secured term loan and revolving credit facilities, as a result of a decrease in forward SOFR interest rates relative to the fixed rates applicable on these secured term loan and revolving credit facilities. This is compared to an unrealized loss on non-designated derivative instruments of $1.1 million for the six months ended June 30, 2023.

Interest Expense. Interest expense increased by $1.6 million, or 5.1%, to $31.9 million for the six months ended June 30, 2024, from $30.4 million for the six months ended June 30, 2023. This is primarily a result of increases SOFR rates and the draw down of facilities that provided financing for the acquisition of five ethylene carriers by the Navigator Greater Bay Joint Venture, offset by repayments made against our available revolving credit facilities.

Income Taxes. Income taxes relate to taxes on our subsidiaries and businesses incorporated around the world including those incorporated in the United States of America. Income taxes were $2.4 million for the six months ended June 30, 2024, compared to $3.1 million for the six months ended June 30, 2023, primarily as a result of movements in current and deferred taxes on our portion of the profits from the Ethylene Export Terminal.

Share of Result of Equity Method Investments. The share of the result of the Company’s 50% ownership in the Export Terminal Joint Venture was an income of $9.1 million for the six months ended June 30, 2024, compared to an income of $11.3 million for the six months ended June 30, 2023. This decrease is a result of reduced throughput rates of 464,072 tons for the six months ended June 30, 2024, compared to 528,313 tons for the six months ended June 30, 2023.

Non-Controlling Interest. We entered into a sale and leaseback arrangement in November 2019 with a wholly-owned special purpose vehicle of a financial institution (“Lessor SPV”). Although we do not hold any equity investments in this Lessor SPV, we have determined that we are the primary beneficiary of this entity and accordingly, we are required to consolidate this VIE into our financial results. The net income attributable to the Lessor SPV was $1.2 million and this is presented as a non-controlling interest for both the six months ended June 30, 2024 and six months ended June 30, 2023.

In September 2022, the Company entered into the Navigator Greater Bay Joint Venture to acquire five ethylene vessels, Navigator Luna, Navigator Solar, Navigator Castor, Navigator Equator and Navigator Vega. The joint venture is owned 60% by the Company and 40% by Greater Bay Gas. The Navigator Greater Bay Joint Venture is accounted for as a consolidated subsidiary in our consolidated financial statements, with the 40% owned by Greater Bay Gas accounted for as a non-controlling interest. A gain attributable to Greater Bay Gas of $4.7 million is presented as the non-controlling interest in our financial results for the six months ended June 30, 2024 compared to $0.3 million for the six months ended June 30, 2023.

Liquidity and Capital Resources

Liquidity and Cash Needs

Our primary sources of funds are cash and cash equivalents, cash from operations, undrawn bank borrowings and proceeds from bond issuances. As of June 30, 2024, we had cash, cash equivalents and restricted cash of $138.5 million.

The Company repaid $23.8 million of the $111.8 million Term Loan and Revolving Credit Facility held with Crédit Agricole in December 2023 and a further $4.7 million during the first quarter of 2024. As of June 30, 2024 we have $28.5 million available to be redrawn by the Company in accordance with the terms of the Term Loan and Revolving Credit Facility which matures in September 2028. As a result, on June 30, 2024 we had available liquidity of $167.0 million.

Our secured term loan facilities and revolving credit facilities require that the borrowers have liquidity of no less than (i) $35.0 million or $50.0 million, as applicable to the relevant loan facility, or (ii) 5% of total debt (which was $41.6 million as of June 30, 2024), whichever is greater.

On August 9, 2024, the Company entered into the August 2024 Facility with Crédit Agricole Corporate and Investment Bank, ING Bank N.V., and Skandinaviska Enskilda Banken AB (Publ), to refinance its March 2019 secured term loan that was due to mature in March 2025, to fund the repurchase of the Navigator Aurora pursuant to the Company’s existing October 2019 sale and leaseback arrangement related to that vessel which, based on a termination notice we issued to the lessor in May 2024, will terminate in October 2024, and for general corporate and working capital purposes. The August 2024 Facility has a term of six years maturing in August 2030, is for a maximum principal amount of $147.6 million, decreases quarterly followed by a final balloon payment in August 2030 of $63.9 million, and bears interest at a rate of Term SOFR plus 190 basis points, which margin includes a 5-basis point sustainability-linked element.

Our primary uses of funds are drydocking and other vessel maintenance expenditures, voyage expenses, vessel operating expenses, general and administrative costs, insurance costs, expenditures incurred in connection with ensuring that our vessels comply with international and regulatory standards, financing expenses, quarterly repayment of bank loans and the Terminal Expansion Project. We also expect to use funds in connection with our Return of Capital policy. In addition, our medium-term and long-term liquidity needs relate to debt repayments, repayment of bonds, potential future vessel newbuildings, related investments, vessel acquisitions, and or related port or terminal projects.

As of June 30, 2024, we had $836.7 million in outstanding obligations, which includes principal repayments on long-term debt, including our bonds, commitments in respect of the Navigator Aurora Facility (as defined below) and office lease commitments. Of the total outstanding obligations, $122.1 million matures during the twelve months ending June 30, 2025, and $714.5 million matures after June 30, 2025.

We believe, given our current cash balances, that our financial resources, including the cash expected to be generated within the year, will be sufficient to meet our liquidity and working capital needs for the next twelve months from August 14, 2024, taking into account our existing capital commitments and debt service requirements. In September 2025 the Company has debt obligations falling due, including a $210 million secured term facility with a balloon repayment of $136 million and the maturity of our unsecured 2020 Bonds in an amount of $91 million. The Company is planning to refinance the secured term facility and the 2020 Bonds, however if the Company’s refinancing efforts are not successful there could be a material adverse effect on the Company’s liquidity and its financial position.

Capital Expenditures

Liquefied gas transportation by sea is a capital-intensive business, requiring significant investment to maintain an efficient fleet and to stay in regulatory compliance.

Although we currently have no contracted newbuildings on order we may place newbuilding orders or acquire additional vessels as part of our growth strategy.

We may invest further in terminal infrastructure, such as the expansion of our existing Ethylene Export Terminal. The total capital contributions required from us to fund our share of the construction cost of the Terminal Expansion Project are expected to be approximately $130.0 million, of which $59.0 million has been contributed as of June 30, 2024, which includes $16.0 million contributed during the second quarter of 2024.

Cash Flows

The following table summarizes our cash, cash equivalents and restricted cash provided by/(used in) operating, investing and financing activities for the six months ended June 30, 2024 and 2023:


	Six months ended June 30, 2023		Six months ended June 30, 2024
	(in thousands)
Net cash provided by operating activities	$	71,272	$	116,509
Net cash (used in) investing activities	(160,601)		(8,342)
Net cash (used in)/provided by financing activities	115,947		(130,357)
Effect of exchange rate changes on cash, cash equivalents and restricted cash	574		2,404
Net increase/(decrease) in cash, cash equivalents and restricted cash	$	27,192	$	(19,786)

Operating Cash Flows. Net cash provided by operating activities for the six months ended June 30, 2024, increased to $116.5 million, from $71.3 million for the six months ended June 30, 2023, an increase of $45.2 million. This increase was primarily due to an increase in net income of $8.5 million (after adding back the non-cash unrealized gains/loss on derivative instruments and our share of the result from equity method investments); and due to changes in working capital of $36.9 million during the six months ended June 30, 2024, compared to the six months ended June 30, 2023.

Net cash flow from operating activities principally depends upon charter rates attainable, fleet utilization, fluctuations in working capital balances, repairs and maintenance activity, amount and duration of drydocks and changes in foreign currency rates.

We are required to drydock each vessel once every five years until it reaches 15 years of age, after which we drydock vessels approximately every two and a half years. Drydocking each vessel, including travelling to and from the drydock, can take approximately 30 days in total being approximately 5-10 days of voyage time to and from the shipyard and approximately 15-20 days of actual drydocking time. Six of our vessels completed their respective drydockings during the six months ended June 30, 2024,

We estimate the current cost of a five-year drydocking for one of our vessels is approximately $1.0 million, a ten-year drydocking cost is approximately $1.3 million, and the 15-year and 17-year drydocking costs are approximately $1.5 million each (including the cost of classification society surveys). As our vessels age and our fleet expands, our drydocking expenses will increase. Ongoing costs for compliance with environmental regulations are primarily included as part of drydocking, such as the requirement to install ballast water treatment plants, and classification society survey costs, with a balance included as a component of our operating expenses.

Investing Cash Flows. Net cash used in investing activities was $8.3 million for the six months ended June 30, 2024, primarily related to contributions to our investment in the Export Terminal Joint Venture via the Terminal Expansion Project of $24.0 million, offset by distributions received from our investment in the Export Terminal Joint Venture of $14.7 million.

Net cash used in investing activities was $160.6 million for the six months ended June 30, 2023, primarily as a result of $191.7 million for the acquisition of four vessels by the Navigator Greater Bay Joint Venture, offset by proceeds from the sale of a vessel of $20.7 million and distributions received from our investment in the Export Terminal Joint Venture of $16.9 million.

Financing Cash Flows. Net cash used in financing activities was $130.4 million for the six months ended June 30, 2024, primarily as a result of our regular quarterly debt repayments totaling $66.2 million, our quarterly dividend payments of $7.3 million and $53.6 million under our Return of Capital policy and our other share repurchase programs.

Net cash provided by financing activities was $115.9 million for the six months ended June 30, 2023 primarily as a result of the drawdowns of $123.6 million on our Greater Bay JV Secured Term Loan to partially finance the acquisition of four vessels; as well as $27.3 million received as a capital contribution from the non-controlling interest for those vessels; a drawdown of $200.0 million on our March 2023 Secured Term Loan, which provided the financing to repay two maturing secured term loan facilities totaling $183.3 million; and offset by $44.6 million under our Return of Capital policy and our other share repurchase programs.

Terminal Facility

General. In March 2019, Navigator Ethylene Terminals LLC (“Marine Terminal Borrower”), our wholly-owned subsidiary, entered into a Credit Agreement (the “Terminal Facility”) with ING Capital LLC and SG Americas Securities, LLC for a maximum principal amount of $75.0 million, to be used for the payment of capital contributions to our Export Terminal Joint Venture for construction costs of our Ethylene Export Terminal.

Term and Facility Limits. The Terminal Facility is now converted into a term loan with a final maturity of December 31, 2025. Based on the committed throughput agreements for the Ethylene Export Terminal, a total of $69.0 million was drawn under the Terminal Facility of which $18.5 million was outstanding as of June 30, 2024.

Interest. The Terminal Facility is subject to quarterly repayments of principal and interest. Interest is payable at a rate of Compounded SOFR ("Comp SOFR") plus 275 to 300 basis points over the remaining term of the facility. We have entered into floating to fixed interest rate swap agreements for approximately 80% of the amounts drawn under the Terminal Facility. The Comp SOFR element of the interest rate payable by the Marine Terminal Borrower under these interest rate swap agreements is 0.369% and 0.3615% per annum.

Financial Covenants. Under the Terminal Facility, the Marine Terminal Borrower must maintain a minimum debt service coverage ratio (as defined in the Terminal Facility) for the prior four calendar fiscal quarters (or shorter period of time if data for the prior four fiscal quarters is not available) of no less than 1.10 to 1.00.

Restrictive Covenants. The Marine Terminal Borrower can only pay dividends if the Marine Terminal Borrower satisfies certain customary conditions, including maintaining a debt service coverage ratio for the immediately preceding four consecutive fiscal quarters and the projected immediately succeeding four consecutive fiscal quarters of not less than 1.20 to 1.00 and where no default or event of default has occurred or is continuing. The Terminal Facility also limits the Marine Terminal Borrower from, among other things, incurring further indebtedness or entering into mergers and divestitures. The Terminal Facility also contains general covenants that require the Marine Terminal Borrower to vote its interest in the Export Terminal Joint Venture to cause the Export Terminal Joint Venture to maintain adequate insurance coverage and maintain its property (but only to the extent the Marine Terminal Borrower has the power under the organizational documents of the Export Terminal Joint Venture to cause such actions).

August 2024 Secured Term Loan and Revolving Credit Facility. On August 9, 2024, the Company entered into the August 2024 Facility with Crédit Agricole Corporate and Investment Bank, ING Bank N.V., and Skandinaviska Enskilda Banken AB (Publ), to refinance its March 2019 secured term loan that was due to mature in March 2025, to fund the repurchase of the Navigator Aurora pursuant to the Company’s existing October 2019 sale and leaseback arrangement related to that vessel which, based on a termination notice we issued to the lessor in May 2024, will terminate in October 2024, and for general corporate and working capital purposes. The August 2024 Facility has a term of six years maturing in August 2030, is for a maximum principal amount of $147.6 million, decreases quarterly followed by a final balloon payment in August 2030 of $63.9 million, and bears interest at a rate of Term SOFR plus 190 basis points, which margin includes a 5-basis point sustainability-linked element.

4 The October 2019 loan facility relates to the Navigator Aurora Facility held within a lessor entity (for which legal ownership resides with a financial institution) that we are required to consolidate under U.S. GAAP into our financial statements as a variable interest entity. Please read Note

14—Variable Interest Entities to the unaudited condensed consolidated financial statements for additional information.

Financial Covenants. Our secured term loan facilities and revolving credit facilities contain financial covenants requiring the borrowers, among other things, to ensure that:

• borrowers maintain a certain level of cash and cash equivalents based on the number of vessels in the facilities, up to an amount of $50 million and;

•borrowers must maintain a minimum ratio of shareholder equity to total assets, or value adjusted total assets, of 30%.

Restrictive Covenants. The secured facilities provide that the borrowers may not declare or pay dividends to shareholders out of operating revenues generated by the vessels securing the indebtedness if an event of default has occurred and is continuing. The secured term loan facilities and revolving credit facilities also typically limit the borrowers from, among other things, incurring further indebtedness or entering into mergers and divestitures. The secured facilities also contain general covenants that require the borrowers to maintain adequate insurance coverage and to maintain the vessels. In addition, the secured term loan facilities include customary events of default, including those relating to a failure to pay principal or interest, a breach of covenant, representation or warranty, a cross-default to other indebtedness and non-compliance with security documents.

Other than as stated, our compliance with the financial covenants listed above is measured as of the end of each fiscal quarter. As of June 30, 2024 we were in compliance with all covenants under our secured term loan facilities and revolving credit facilities.

The borrowers are also required to deliver semi-annual compliance certificates, which include providing valuations of the vessels securing the applicable facility from an independent ship broker. Upon delivery of the valuation, if the market value of the collateral vessels is less than 125% to 135% of the outstanding indebtedness under the applicable facilities, the borrowers must either provide additional collateral or repay any amount in excess of 125% to 135% of the market value of the collateral vessels, as applicable. This covenant is measured semi-annually on June 30 and December 31 each year.

2020 Senior Unsecured Bonds

General. On September 10, 2020, we issued senior unsecured bonds in an aggregate principal amount of $100 million with Nordic Trustee AS

as the bond trustee (the “2020 Bonds”). The net proceeds of the issuance of the 2020 Bonds were used to redeem in full all of our previously outstanding 2017 Bonds. The 2020 Bonds are governed by Norwegian law and listed on the Nordic ABM which is operated and organized by Oslo Børs ASA.

In September 2023 we purchased $9.0 million of the 2020 Bonds in the open market using cash on hand. These purchased 2020 Bonds have not been cancelled or redeemed and the Company intends to hold the bonds to maturity.

Interest. Interest on the 2020 Bonds is payable at a fixed rate of 8.0% per annum, calculated on a 360-day year basis. Interest is payable semi- annually in arrears on March 10 and September 10 of each year.

Maturity. The 2020 Bonds mature on September 10, 2025 and become repayable on that date.

Optional Redemption. We may redeem the 2020 Bonds, in whole or in part at any time. Any 2020 Bonds redeemed; up until September 9, 2023 will be priced at the aggregate of the net present value (based on the Norwegian government bond rate plus 50 basis points) of 103.2% of par and interest payable up to September 9, 2023; from September 10, 2023 up until September 9, 2024, are redeemable at 103.2% of par; from September 10,

2024 up until March 9, 2025, are redeemable at 101.6% of par; and from March 10, 2025 to the maturity date are redeemable at 100% of par; in each case, in cash plus accrued interest.

Additionally, upon the occurrence of a “Change of Control Event” (as defined in the bond agreement for the 2020 Bonds, (the “2020 Bond Agreement”)), the holders of 2020 Bonds have the option to require us to repay such holders’ outstanding principal amount of 2020 Bonds at 101% of par, plus accrued interest.

Financial Covenants. The 2020 Bond Agreement contains financial covenants requiring us, among other things, to ensure that:

•we and our subsidiaries maintain a minimum liquidity of no less than $35 million; and

•we and our subsidiaries maintain an Equity Ratio (as defined in the 2020 Bond Agreement) of at least 30%.

Our compliance with the covenants listed above is measured as of the end of each fiscal quarter. As of June 30, 2024, we were in compliance with all covenants under the 2020 Bonds.

Restrictive Covenants. The 2020 Bonds provide that we may declare or pay dividends to shareholders provided the Company maintains a minimum liquidity of $60 million unless an event of default has occurred and is continuing. The 2020 Bond Agreement also limits us and our subsidiaries from, among other things, entering into mergers and divestitures, engaging in transactions with affiliates or incurring any additional liens which would have a material adverse effect. In addition, the 2020 Bond Agreement includes customary events of default, including those relating to a failure to pay principal or interest, a breach of covenant, false representation or warranty, a cross-default to other indebtedness, the occurrence of a material adverse effect, or our insolvency or dissolution.

Lessor VIE Debt

In October 2019, we entered into a sale and leaseback transaction to refinance one of our vessels, Navigator Aurora¸ with a lessor, OCY Aurora Ltd, a special purpose vehicle (“SPV”) and wholly owned subsidiary of Ocean Yield Malta Limited. The SPV was determined to be a VIE. We are deemed under U.S. GAAP to be the primary beneficiary of the VIE, and as a result, we are required to consolidate the SPV into our results. The loan described below under “—Navigator Aurora Facility” relates to the VIE. Although we have no control over the funding arrangements of this entity, we are required to consolidate this loan facility into our financial results.

Upon the occurrence of a “Change of Control Event” (as defined in the sale and leaseback agreement), the lessor has the option to require us to repurchase Navigator Aurora at 103% of the outstanding lease amount, plus costs and expenses directly attributable to the termination of the lessor’s financing arrangements, such as break costs for swap arrangements.

Navigator Aurora Facility In October 2019, the SPV, which owns Navigator Aurora, entered into secured financing agreements for $69.1 million consisting of a USD denominated loan facility, the “Navigator Aurora Facility”. The Navigator Aurora Facility is a seven year unsecured loan provided by OCY Malta Limited, the parent of OCY Aurora Ltd., The Navigator Aurora Facility is subordinated to a further bank loan where OCY Aurora Ltd is the guarantor and Navigator Aurora is pledged as security. The Navigator Aurora Facility bears interest at 3-month Term SOFR, a credit adjustment spread, plus a margin of 185 basis points and is repayable by the SPV with a balloon payment on maturity. As of June 30, 2024, $38.1 million in borrowings were outstanding under the Navigator Aurora Facility (December 31, 2023, $41.3 million).

Critical Accounting Estimates

We prepare our consolidated financial statements in accordance with U.S. GAAP, which requires us to make estimates in the application of our accounting policies based on our best assumptions, judgments and opinions. On a regular basis, management reviews the accounting policies, assumptions, estimates and judgments to ensure that our consolidated financial statements are presented fairly and in accordance with U.S. GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates, and such differences could be material. For a description of our material accounting policies, please read Note 2—Summary of Significant Accounting Policies to the Company's 2023 Annual Report.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk from changes in interest rates and foreign currency fluctuations, as well as inflation. We use interest rate swaps to manage some of our interest rate risks. We do not use interest rate swaps or any other financial instruments for trading or speculative purposes.

Interest Rate Risk

We are exposed to the impact of interest rate changes through borrowings that require us to make interest payments based on SOFR. Our wholly-owned subsidiaries and certain of our vessel-owning subsidiaries are party to secured term loan and revolving credit facilities that bear interest at rates of SOFR plus between 185 and 276 basis points. At June 30, 2024, $269.5 million of our outstanding debt was subject to interest rate swaps and therefore is not exposed to changes in interest rate movements, whereas $453.0 million was subject to variable interest rates. Based on this, a hypothetical increase in SOFR of 100 basis points would result in an increase of $4.5 million in annual interest expense on our indebtedness outstanding as of June 30, 2024.

We use interest rate swaps to reduce our exposure to market risk from changes in interest rates. The principal objective of these contracts is to minimize the risks and costs associated with our floating-rate debt. The Company is exposed to the risk of credit loss in the event of non-performance by the counterparty to the interest rate swap agreements.

Foreign Currency Exchange Rate Risk

Our primary economic environment is the international shipping market. This market utilizes the U.S. Dollar as its functional currency. Consequently, most of our revenues are in U.S. Dollars although some charter hires are paid in Indonesian Rupiah. Our expenses however are in the currency invoiced by each supplier, and we remit funds in various currencies. We incur some vessel operating expenses and general and administrative costs in foreign currencies, primarily Euros, Pound Sterling, Danish Kroner, and Polish Zloty, and therefore there is a transactional risk that currency fluctuations could have a negative effect on our cash flows and financial condition. We believe these adverse effects would not be material and we have not entered into any derivative contracts to mitigate our exposure to foreign currency exchange rate risk as of June 30, 2024.

Inflation

We are exposed to increases in operating costs arising from various vessel operations, including crewing, vessel repair costs, drydocking costs, insurance and fuel prices as well as from general inflation, and we are subject to fluctuations as a result of general market forces. Increases in bunker costs could have a material effect on our future operations if the number and duration of our voyage charters or Contract of Affreightment ("COA") increases. In the case of the 47 vessels owned and commercially managed by us as of June 30, 2024, 32 were employed on time charter and as such it is the charterers who pay for the fuel on those vessels. If our vessels are employed under voyage charters or COA, freight rates are generally sensitive to the

price of fuel. However, a sharp rise in bunker prices may have a temporary negative effect on our results since freight rates generally adjust only after bunker prices settle at a higher level.

Credit Risk

We may be exposed to credit risks in relation to vessel employment and at times we may have multiple vessels employed by one charterer. We consider and evaluate the concentration of credit risk continuously and perform ongoing evaluations of these charterers for credit risk. At June 30, 2024, no more than four of our vessels were employed by the same charterer. We invest our surplus funds with reputable financial institutions, and at June 30, 2024, all such deposits had maturities of no more than three months, in order to provide the Company with flexibility to meet all requirements for working capital and capital investments.

Notes to the Condensed Consolidated Financial Statements (Unaudited)

1. General Information and Basis of Presentation

General Information

Navigator Holdings Ltd. (the “Company”), the ultimate parent company of the Navigator Group of companies, is registered in the Republic of the Marshall Islands. The Company has a core business of owning and operating a fleet of liquefied gas carriers. As of June 30, 2024, the Company owned and operated 56 gas carriers (the “Vessels”) each having a cargo capacity of between 3,770 cbm and 38,000 cbm, of which 25 were ethylene and ethane-capable vessels.

The Company entered into a joint venture (the “Navigator Greater Bay Joint Venture”) with Greater Bay Gas Co. Ltd. (“Greater Bay Gas”) in September 2022, which joint venture entity has acquired two 17,000 cbm, 2018-built ethylene-capable liquefied gas carriers and three 22,000 cbm, 2019-built ethylene capable liquefied gas carriers. The vessels are currently commercially managed through the in-house Luna Pool and technically managed by a third party, PG Shipmanagement of Singapore.

The Company owns a 50% share, through a joint venture (the “Export Terminal Joint Venture”), of an ethylene export marine terminal at Morgan’s Point, Texas on the Houston Ship Channel ( the “Ethylene Export Terminal”), capable of exporting in excess of one million tons of ethylene per year.

Unless the context otherwise requires, all references in the consolidated financial statements to “our”,” we” and “us” refer to the Company.

Basis of Presentation

These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and related Securities and Exchange Commission (“SEC”) rules for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In our opinion, all adjustments consisting of normal recurring items, necessary for a fair statement of financial position, operating results and cash flows have been included in the unaudited interim condensed consolidated financial statements and related notes. The unaudited interim condensed consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements and related notes for the year ended December 31, 2023 included in our Annual Report on Form 20-F filed with the SEC on March 27, 2024 (the “2023 Annual Report”). The year-end condensed balance sheet data was derived from the audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. The results for the six months ended June 30, 2024, are not necessarily indicative of results for the year ending December 31, 2024, or any other future periods.

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company, its subsidiaries and variable interest entities (“VIE”) for which the Company is a primary beneficiary and are also consolidated (please read Note 14—Variable Interest Entities for additional information). All intercompany accounts and transactions have been eliminated on consolidation.

The results of operations are subject to seasonal and other fluctuations and are therefore not necessarily indicative of results that may otherwise be expected for the entire year.

Management has evaluated the Company’s ability to continue as a going concern and considered the conditions and events that could raise substantial doubt about the Company’s ability to continue as a going concern within 12 months after these financial statements are issued. As part of the assessment, management has considered the following:

•our current financial condition and liquidity sources, including current funds available and forecasted future cash flows;

•environmental regulations such as those affecting vessels' Energy Efficiency Existing Ship Index (“EEXI”); and

•the total capital contributions required for the Terminal Expansion Project (as defined below).

Management has determined that it is appropriate to continue to adopt the going concern basis in preparing the financial statements.

In September 2025, which is outside the 12-month going concern period, the Company has debt obligations falling due, including a $210 million secured term facility with a balloon repayment of $136.0 million and the maturity of our unsecured 2020 Bonds in an amount of $91 million. The Company is planning to refinance the secured term facility and the 2020 Bonds, however if the Company’s refinancing efforts are not successful there could be a material adverse effect on the Company’s liquidity and its financial position.

A discussion of the Company’s significant accounting policies can be found in the Company’s consolidated financial statements included in the Company's 2023 Annual Report. There have been no material changes to these policies in the six months ended June 30, 2024.

2. Operating Revenues

The following table discloses operating revenues by contract type for the three and six months ended June 30, 2024 and 2023:


	Three months ended June 30, 2023		Three months ended June 30, 2024		Six months ended June 30, 2023		Six months ended June 30, 2024
	(in thousands)

Total operating revenues	$	135,335	$	146,676	$	271,337	$	280,831

As of June 30, 2024, 32 of the Company’s 47 operated vessels (excluding the nine vessels operating within the independently managed Unigas Pool) were subject to time charters, 26 of which will expire within one year, five of which will expire within three years, and one of which will expire between three to five years from the balance sheet date (December 31, 2023: 38 of the Company’s 47 operated vessels were subject to time charters, 27 of which will expire within one year, five of which will expire within three years and six of which will expire between three to five years). The estimated undiscounted cash flows for committed time charter revenues that are expected to be received on an annual basis for ongoing time charters, as of June 30, 2024, are as follows:


			(in thousands of U.S. dollars)
Within 1 year			196,750
In the second year			64,995
In the third year			17,113
In the fourth year			1,177

For time charter revenues accounted for under ASC 842, the amount of accrued income on the Company’s unaudited condensed consolidated balance sheet as of June 30, 2024, was $0.9 million (December 31, 2023: $1.0 million).

Voyage Charter revenues

Voyage charter revenues, which include revenues from contracts of affreightment, are shown net of address commissions.

As of June 30, 2024, for voyage charters and contracts of affreightment services accounted for under ASC 606, the amount of contract assets reflected within accrued income on the Company’s unaudited condensed consolidated balance sheet was $6.8 million (December 31, 2023: $1.3 million). Changes in the contract asset balance at the balance sheet dates reflect income accrued after loading of the cargo commences but before an invoice has been raised to the charterer, as well as changes in the number of the Company’s vessels contracted under voyage charters or contracts of affreightment.

The period opening and closing balance of receivables from voyage charters, including contracts of affreightment, was $18.3 million and $6.9 million, respectively, as of June 30, 2024 (December 31, 2023: $5.1 million and $18.3 million, respectively) and is reflected within net accounts receivable on the Company’s unaudited condensed consolidated balance sheet.

The amount allocated to costs incurred to fulfill a contract with a charterer, which are costs incurred following the commencement of a contract or charter party but before the loading of the cargo commences, was $1.1 million as of June 30, 2024 (December 31, 2023: $1.0 million) and is reflected within prepaid expenses and other current assets on the Company’s unaudited condensed consolidated balance sheet.

Azane Fuel Solutions AS ("Azane")

Azane, a joint venture between ECONNECT Energy AS and Amon Maritime AS, both of Norway, was founded in Norway in 2020 as a company that develops proprietary technology and services for ammonia fuel handling to facilitate the transition to green fuels for shipping. The Company acquired a 14.5% equity interest in Azane on October 25, 2023. It was recognized initially at cost.

Subject to customary conditions, Azane intends to build the world’s first ammonia bunkering network, with Yara Clean Ammonia ("Yara") already pre-ordering 15 units from Azane. The first green ammonia bunkering units are scheduled to be delivered in 2025 enabling a low-carbon fuel offering to shipowners. The investment made by Yara and Navigator is expected to enable Azane to begin construction of its first bunkering unit for ammonia supply in Norway, aiming to kickstart the transition to zero-carbon fuels for maritime transportation. Future value creation for Azane is expected to come through international expansion with its bunkering solutions and the broadening of its offerings in ammonia fuel handling technology.

7. Derivative Instruments Accounted for at Fair Value

The following table includes the estimated fair value of those assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2023 and June 30, 2024.


		December 31, 2023	June 30, 2024
		(in thousands)
	Fair Value Hierarchy Level	Fair Value Asset	Fair Value Asset
Interest rate swap agreements	Level 2	$14,674	$12,647

The Company uses derivative instruments in accordance with its overall risk management policy to mitigate the risk of unfavorable fluctuations in foreign exchange and interest rate movements.

The Company held no derivatives designated as hedges as of December 31, 2023 or June 30, 2024.

Fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. The fair value accounting standard establishes a three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2—Include other inputs that are directly or indirectly observable in the marketplace.

Level 3—Unobservable inputs which are supported by little or no market activity.

Interest Rate risk

The Company has a number of existing vessel loan facilities with associated fixed interest rate swaps. As of June 30, 2024, the interest rate swaps had a positive fair value to the Company of $12.6 million (December 31, 2023, a positive fair value to the Company of $14.7 million). There were unrealized losses of $1.6 million on the fair value of the swaps for the three months ended June 30, 2024 (three months ended June 30, 2023, an unrealized gain of $3.2 million). There were unrealized losses of $2.0 million on the fair value of the swaps for the six months ended June 30, 2024 (six months ended June 30, 2023, an unrealized loss of $1.1 million).

These fixed interest rate swaps are typically entered into with the financial institutions which are lenders under on the loan facilities. The interest rate payable by the Company under these interest rate swap agreements is between 0.3615% and 2.137%. The interest rate receivable by the Company under these interest rate swap agreements is 3-month SOFR, calculated on a 360-day year basis and which resets every three months.

All interest rate swaps above are remeasured to fair value at each reporting date and have been categorized as level two on the fair value measurement hierarchy. The remeasurement to fair value has no impact on the cash flows at the reporting date. There is no requirement for cash collateral to be placed with the swap providers under these swap agreements and there is no effect on restricted cash as of June 30, 2024.

Foreign Currency Exchange Rate risk

All foreign currency-denominated monetary assets and liabilities are revalued and are reported in the Company’s functional currency based on the prevailing exchange rate at the end of the period. These foreign currency transactions fluctuate based on the strength of the U.S. Dollar. The remeasurement of all foreign currency-denominated monetary assets and liabilities at each reporting date results in unrealized foreign currency exchange differences which do not impact our cash flows.

Credit risk

The Company is exposed to credit losses in the event of non-performance by the counterparties to its interest rate swap agreements. As of June 30, 2024, the Company is exposed to credit risk as the interest rate swaps were in an asset position from the perspective of the Company. In order to minimize counterparty risk, the Company only enters into derivative transactions with counterparties that are reputable financial institutions, highly rated by a recognized rating agency.

The fair value of our interest rate swap agreements is the estimated amount that we would pay/receive to sell or transfer the swap at the reporting date, taking into account current interest rates and the current credit worthiness of the swap counterparties. The estimated amount is the present value of future cash flows, adjusted for credit risk. The Company transacts all of these derivative instruments through investment-grade rated financial institutions at the time of the transaction. The amount recorded as a derivative asset or liability could vary by a material amount in the near term if credit markets are volatile or if credit risk were to change significantly.

The fair value of our interest rate swap agreements at the end of each period is most significantly affected by the interest rate implied by the benchmark interest yield curve, including its relative steepness. Interest rates and foreign exchange rates have experienced significant volatility in recent years in both the short and long term. While the fair value of our swap agreements is typically more sensitive to changes in short-term rates, significant changes in long-term benchmark interest, foreign exchange rates and the credit risk of the counterparties of the Company also materially impact the fair values of our swap agreements.

8. Fair Value of Financial Instruments Not Accounted for at Fair Value

F-12

The principal financial assets of the Company as of June 30, 2024, and December 31, 2023, consist of cash, cash equivalents, and restricted cash and accounts receivable. The principal financial liabilities of the Company as of June 30, 2024, and December 31, 2023, consist of accounts payable, accrued expenses and other liabilities, secured term loan facilities, revolving credit facilities and the 2020 Bonds and do not include deferred financing costs.

The carrying values of cash, cash equivalents and restricted cash, accounts receivable, accounts payable, accrued expenses and other liabilities are reasonable estimates of their fair value due to the short-term nature or liquidity of these financial instruments.

Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2—Include other inputs that are directly or indirectly observable in the marketplace.

Level 3—Unobservable inputs which are supported by little or no market activity.

The 2020 Bonds are classified as a level two liability and the fair values have been calculated based on the most recent trades of the bond on the Oslo Børs prior to June 30, 2024. These trades are infrequent and therefore not considered to be an active market.

The fair value of secured term loan facilities and revolving credit facilities is estimated to approximate the carrying value in the balance sheet since they bear a variable interest rate, which is reset quarterly. This has been categorized at level two on the fair value measurement hierarchy as of June 30, 2024.

The following table includes the estimated fair value and carrying value of those assets and liabilities where the fair value approximate carrying value. The table excludes cash, cash equivalents, restricted cash, accounts receivable, accounts payable, accrued expenses and other liabilities because the fair value approximates carrying value and, for accounts receivable and payable, are due in one year or less.

9. Earnings per share

Basic earnings per share is calculated by dividing the net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated by adjusting the weighted average number of common shares used for calculating basic earnings per share for the effects of all potentially dilutive shares. The following table shows the calculation of both the basic and diluted number of weighted average outstanding shares for the three and six months ended June 30, 2024 and 2023:


	Three months ended June 30, 2023		Three months ended June 30, 2024		Six months ended June 30, 2023		Six months ended June 30, 2024

Restricted share grant activity for the year ended December 31, 2023, and the six months ended June 30, 2024, was as follows:


	Number of non-vested restricted shares	Weighted average grant date fair value		Weighted average remaining contractual term (years)
Balance as of January 1, 2023	115,693	$	10.16	1.04
Granted	47,829	12.45
Vested	(78,144)	10.16
Balance as of December 31, 2023	85,378	11.44		0.81
Granted	54,851	15.03
Vested	(41,944)	11.92
Balance as of June 30, 2024	98,285	$	13.24	1.12

We account for forfeitures as they occur. Using the graded straight-line method of expensing the restricted stock grants, the weighted average estimated value of the shares calculated at the date of grant is recognized as compensation cost in the unaudited condensed consolidated statement of operations over the period to the vesting date.

During the six months ended June 30, 2024, the Company recognized $281,557 in share-based compensation costs relating to share grants (six months ended June 30, 2023: $457,751). As of June 30, 2024, there was a total of $717,882 unrecognized compensation costs relating to the expected future vesting of share-based awards (December 31, 2023: $400,282) which are expected to be recognized over a weighted average period of 1.12 years (December 31, 2023: 0.81 years).

Share options

Share options issued under the 2013 Plan are exercisable between the third and tenth anniversary of the grant date, after which they lapse. The fair value of any option issued is calculated on the date of the grant based on the Black-Scholes valuation model. Expected volatility is based on the historic volatility of the Company’s stock price and other factors. The expected term of the options granted is anticipated to occur in the range between 4 and 6.5 years. The risk-free rate is the rate adopted from the U.S. Government Zero Coupon Bond.

The movements in the outstanding share options during the year ended December 31, 2023, and the six months ended June 30, 2024, were as follows:

F-14

1 We have committed to invest further in terminal infrastructure, such as expanding our existing Ethylene Export Terminal. As at June 30, 2024 the remaining capital contributions required from us to the Export Terminal Joint Venture for the Terminal Expansion Project are expected to be approximately $71 million.

2 The Company occupies office space in London with a lease that commenced in January 2022 for a period of 10 years with a mutual break option in January 2027, which is the fifth anniversary of the lease commencement date. The annual gross rent under this lease is approximately $1.1 million, with an initial rent-free period of 27 months, of which 13 months of the rent free period is repayable in the event that the break option is exercised.

The Company entered into a lease for office space in Houston that expires on March 31, 2025. The annual gross rent under this lease is approximately $60,000.

The lease term for our representative office in Gdynia, Poland was revised during 2021 for an amended period to May 31, 2025. The gross rent per year is approximately $64,000.

The Company occupies office space in Copenhagen, Denmark with a lease that commenced in September 2021 that expires in June 2025. The gross rent per year is approximately $180,000.

The weighted average remaining contractual lease term for the above four office leases on June 30, 2024, was 2.47 years (December 31, 2023: 3.88 years).

5 The aggregate intrinsic value of stock options is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s common stock for options that had exercise prices lower than the fair value of the Company’s share price.

3 The Navigator Aurora Facility is a loan facility held within a lessor entity (for which legal ownership resides with financial institutions) that we are required to consolidate under U.S. GAAP into our financial statements as a variable interest entity. Please read Note 14—Variable Interest Entities to our consolidated financial statements.

12. Operating Lease Liabilities

The Company’s unaudited condensed consolidated balance sheet includes a right-of-use (“ROU”) asset and a corresponding liability for operating lease contracts where the Company is a lessee. The discount rate used to measure the lease liability presented on the Company’s unaudited condensed consolidated balance sheet is the incremental cost of borrowing since the rate implicit in the lease cannot be determined.

The liabilities described below are for the Company’s offices in London, Gdynia, Copenhagen and Houston which are denominated in various currencies. At June 30, 2024, the weighted average discount rate across the four leases was 2.93% (December 31, 2023: 2.95%).

At June 30, 2024, based on the remaining lease liabilities, the weighted average remaining operating lease term was 2.46 years (December 31, 2023: 3.17 years ).

Under ASC 842, the ROU asset is a non-monetary asset and is remeasured into the Company’s reporting currency using the exchange rate for the applicable currency as at the adoption date of ASC 842. The operating lease liability is a monetary liability and is remeasured quarterly using current exchange rates, with changes recognized in a manner consistent with other foreign currency-denominated liabilities within general and administrative expenses in the unaudited condensed consolidated statements of comprehensive income.

A maturity analysis of the annual undiscounted cash flows of the Company’s operating lease liabilities as of December 31, 2023 and June 30, 2024, is presented in the following table:

Amounts included in restricted cash represent cash in blocked deposit accounts that are required to be deposited in accordance with the terms of a number of secured term loans with banking institutions. These funds are not available for daily operational use.

14. Variable Interest Entities

As of December 31, 2023 and June 30, 2024, the Company has consolidated 100% of PT Navigator Khatulistiwa, a VIE for which the Company is deemed to be the primary beneficiary, i.e. it has a controlling financial interest in this entity with the power to direct the activities that most significantly impact the entity’s economic performance and has the right to residual gains or the obligation to absorb losses that could potentially be significant to the VIE. The Company owns 49% of PT Navigator Khatulistiwa common stock, all of its secured debt and has voting control. All economic interests in the residual net assets reside with the Company. By virtue of the accounting principle of consolidation, transactions between PT Navigator Khatulistiwa and the Company are eliminated on consolidation.

In October 2019, the Company entered into a sale and leaseback to refinance one of its vessels, Navigator Aurora, with OCY Aurora Ltd., a Maltese limited liability company. OCY Aurora Ltd. is a wholly owned subsidiary of Ocean Yield Malta Limited, whose parent is Ocean Yield ASA, a listed company on the Oslo stock exchange. The Company does not hold any shares or voting rights in OCY Aurora Ltd. Under U.S. GAAP the entity, OCY Aurora Ltd, is considered to be a VIE.

F-16

As of December 31, 2023, and June 30, 2024, the Company has consolidated 100% of OCY Aurora Ltd., the lessor variable interest entity (‘‘lessor VIE’’). We have leased Navigator Aurora from OCY Aurora Ltd. under a sale and leaseback arrangement. The lessor VIE is a special purpose vehicle (“SPV”) wholly owned by OCY Aurora Ltd. a financial institution. The Company has concluded that it has a variable interest in the SPV because the bareboat charter has fixed price call options to acquire the Navigator Aurora from the SPV at various dates throughout the 13 year lease/bareboat charter term, commencing from the fifth year, initially at USD 44.8 million. The call options are considered to be variable interests as each option effectively transfers substantially all of the rewards from Navigator Aurora to us and limits the SPV’s ability to benefit from the rewards of ownership.

The Company has performed an analysis and concluded that we exercise power through the exercise of the call options in the lease agreement. The call options, although not an activity of the SPV, if exercised would significantly impact the SPV’s economic performance as the SPV owns no other revenue generating assets. The options transfer to the Company the right to receive benefits as they are agreed at a predetermined price. The SPV is protected from decreases in the value of the vessel, as if the vessel’s market value were to decline, the call option provides the SPV protection up to the point where it would not be economically viable for the Company to exercise the option. In addition, the Company has the power to direct decisions over the activities and care of the vessel which directly impact its value such as for the day-to-day commercial, technical management and operation of the vessel.

Following the above, the SPV is categorized under U.S. GAAP as a VIE and the Company has concluded it is the primary beneficiary and must therefore consolidate the SPV within its financial statements.

We own a 25% and 40% share in equity of Navigator Crewing Services Philippines Inc. (“NCSPI”, “Navigator Crewing”) and Navigator Gas Services Philippines Inc. (“NSSPI”), respectively. These companies were established primarily to provide marine services as principals or agents to ship owners, ship operators, managers engaged in international maritime business and business support services, respectively.

The Company has determined that it has a variable interest in NCSPI and NSSPI and is considered to be the primary beneficiary as a result of having a controlling financial interest in the entities and has the power to direct the activities that most significantly impact NCSPI’s and NSSPI’s economic performance.

As of June 30, 2024, the Company's VIE’s had total assets and liabilities of $171.0 million and $58.7 million respectively which have been included in the Company’s consolidated balance sheet as of that date (December 31, 2023: $179.8 million and $61.4 million, respectively).

General Information and Basis of Presentation	Jun. 30, 2024
Accounting Policies [Abstract]
General Information and Basis of Presentation	1. General Information and Basis of Presentation General Information Navigator Holdings Ltd. (the “Company”), the ultimate parent company of the Navigator Group of companies, is registered in the Republic of the Marshall Islands. The Company has a core business of owning and operating a fleet of liquefied gas carriers. As of June 30, 2024, the Company owned and operated 56 gas carriers (the “Vessels”) each having a cargo capacity of between 3,770 cbm and 38,000 cbm, of which 25 were ethylene and ethane-capable vessels. The Company entered into a joint venture (the “Navigator Greater Bay Joint Venture”) with Greater Bay Gas Co. Ltd. (“Greater Bay Gas”) in September 2022, which joint venture entity has acquired two 17,000 cbm, 2018-built ethylene-capable liquefied gas carriers and three 22,000 cbm, 2019-built ethylene capable liquefied gas carriers. The vessels are currently commercially managed through the in-house Luna Pool and technically managed by a third party, PG Shipmanagement of Singapore. The Company owns a 50% share, through a joint venture (the “Export Terminal Joint Venture”), of an ethylene export marine terminal at Morgan’s Point, Texas on the Houston Ship Channel ( the “Ethylene Export Terminal”), capable of exporting in excess of one million tons of ethylene per year. Unless the context otherwise requires, all references in the consolidated financial statements to “our”,” we” and “us” refer to the Company. Basis of Presentation These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and related Securities and Exchange Commission (“SEC”) rules for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In our opinion, all adjustments consisting of normal recurring items, necessary for a fair statement of financial position, operating results and cash flows have been included in the unaudited interim condensed consolidated financial statements and related notes. The unaudited interim condensed consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements and related notes for the year ended December 31, 2023 included in our Annual Report on Form 20-F filed with the SEC on March 27, 2024 (the “2023 Annual Report”). The year-end condensed balance sheet data was derived from the audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. The results for the six months ended June 30, 2024, are not necessarily indicative of results for the year ending December 31, 2024, or any other future periods. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company, its subsidiaries and variable interest entities (“VIE”) for which the Company is a primary beneficiary and are also consolidated (please read Note 14—Variable Interest Entities for additional information). All intercompany accounts and transactions have been eliminated on consolidation. The results of operations are subject to seasonal and other fluctuations and are therefore not necessarily indicative of results that may otherwise be expected for the entire year. Management has evaluated the Company’s ability to continue as a going concern and considered the conditions and events that could raise substantial doubt about the Company’s ability to continue as a going concern within 12 months after these financial statements are issued. As part of the assessment, management has considered the following: •our current financial condition and liquidity sources, including current funds available and forecasted future cash flows; •the severity and duration of any world events and armed conflicts, including the Russian-Ukraine war, conflicts in the Israel-Gaza region and the potential for broader conflict in the Middle East involving Iran and other nations, and associated repercussions to supply and demand for oil and gas and the economy generally as well as possible effects of trade disruptions; •environmental regulations such as those affecting vessels' Energy Efficiency Existing Ship Index (“EEXI”); and •the total capital contributions required for the Terminal Expansion Project (as defined below). Management has determined that it is appropriate to continue to adopt the going concern basis in preparing the financial statements. In September 2025, which is outside the 12-month going concern period, the Company has debt obligations falling due, including a $210 million secured term facility with a balloon repayment of $136.0 million and the maturity of our unsecured 2020 Bonds in an amount of $91 million. The Company is planning to refinance the secured term facility and the 2020 Bonds, however if the Company’s refinancing efforts are not successful there could be a material adverse effect on the Company’s liquidity and its financial position. A discussion of the Company’s significant accounting policies can be found in the Company’s consolidated financial statements included in the Company's 2023 Annual Report. There have been no material changes to these policies in the six months ended June 30, 2024. Recent Accounting Pronouncements New accounting standards issued as of June 30, 2024 may affect future reporting by Navigator Holdings Ltd. Refer to the Company's 2023 Annual Report for a comprehensive list of accounting pronouncements. There are no other new accounting pronouncements that are expected to have a material impact on the financial reporting by the Company for the six months ended June 30, 2024

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities As of December 31, 2023 and June 30, 2024, the Company has consolidated 100% of PT Navigator Khatulistiwa, a VIE for which the Company is deemed to be the primary beneficiary, i.e. it has a controlling financial interest in this entity with the power to direct the activities that most significantly impact the entity’s economic performance and has the right to residual gains or the obligation to absorb losses that could potentially be significant to the VIE. The Company owns 49% of PT Navigator Khatulistiwa common stock, all of its secured debt and has voting control. All economic interests in the residual net assets reside with the Company. By virtue of the accounting principle of consolidation, transactions between PT Navigator Khatulistiwa and the Company are eliminated on consolidation. In October 2019, the Company entered into a sale and leaseback to refinance one of its vessels, Navigator Aurora, with OCY Aurora Ltd., a Maltese limited liability company. OCY Aurora Ltd. is a wholly owned subsidiary of Ocean Yield Malta Limited, whose parent is Ocean Yield ASA, a listed company on the Oslo stock exchange. The Company does not hold any shares or voting rights in OCY Aurora Ltd. Under U.S. GAAP the entity, OCY Aurora Ltd, is considered to be a VIE. As of December 31, 2023, and June 30, 2024, the Company has consolidated 100% of OCY Aurora Ltd., the lessor variable interest entity (‘‘lessor VIE’’). We have leased Navigator Aurora from OCY Aurora Ltd. under a sale and leaseback arrangement. The lessor VIE is a special purpose vehicle (“SPV”) wholly owned by OCY Aurora Ltd. a financial institution. The Company has concluded that it has a variable interest in the SPV because the bareboat charter has fixed price call options to acquire the Navigator Aurora from the SPV at various dates throughout the 13 year lease/bareboat charter term, commencing from the fifth year, initially at USD 44.8 million. The call options are considered to be variable interests as each option effectively transfers substantially all of the rewards from Navigator Aurora to us and limits the SPV’s ability to benefit from the rewards of ownership. The Company has performed an analysis and concluded that we exercise power through the exercise of the call options in the lease agreement. The call options, although not an activity of the SPV, if exercised would significantly impact the SPV’s economic performance as the SPV owns no other revenue generating assets. The options transfer to the Company the right to receive benefits as they are agreed at a predetermined price. The SPV is protected from decreases in the value of the vessel, as if the vessel’s market value were to decline, the call option provides the SPV protection up to the point where it would not be economically viable for the Company to exercise the option. In addition, the Company has the power to direct decisions over the activities and care of the vessel which directly impact its value such as for the day-to-day commercial, technical management and operation of the vessel. Following the above, the SPV is categorized under U.S. GAAP as a VIE and the Company has concluded it is the primary beneficiary and must therefore consolidate the SPV within its financial statements. We own a 25% and 40% share in equity of Navigator Crewing Services Philippines Inc. (“NCSPI”, “Navigator Crewing”) and Navigator Gas Services Philippines Inc. (“NSSPI”), respectively. These companies were established primarily to provide marine services as principals or agents to ship owners, ship operators, managers engaged in international maritime business and business support services, respectively. The Company has determined that it has a variable interest in NCSPI and NSSPI and is considered to be the primary beneficiary as a result of having a controlling financial interest in the entities and has the power to direct the activities that most significantly impact NCSPI’s and NSSPI’s economic performance. As of June 30, 2024, the Company's VIE’s had total assets and liabilities of $171.0 million and $58.7 million respectively which have been included in the Company’s consolidated balance sheet as of that date (December 31, 2023: $179.8 million and $61.4 million, respectively).

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On August 9, 2024, the Company entered into the August 2024 Facility with Crédit Agricole Corporate and Investment Bank, ING Bank N.V., and Skandinaviska Enskilda Banken AB (Publ), to refinance its March 2019 secured term loan that was due to mature in March 2025, to fund the repurchase of the Navigator Aurora pursuant to the Company’s existing October 2019 sale and leaseback arrangement related to that vessel which, based on a termination notice we issued to the lessor in May 2024, will terminate in October 2024, and for general corporate and working capital purposes. The August 2024 Facility has a term of six years maturing in August 2030, is for a maximum principal amount of $147.6 million, decreases quarterly followed by a final balloon payment in August 2030 of $63.9 million, and bears interest at a rate of Term SOFR plus 190 basis points, which margin includes a 5-basis point sustainability-linked element. On August 14, 2024, the Company's Board of Directors declared a cash dividend of $0.05 per share of the Company’s common stock for the three months ended June 30, 2024, payable on September 24, 2024 to all shareholders of record as of the close of business New York time on September 3, 2024. The aggregate amount of the dividend is expected to be approximately $3.6 million, which the Company anticipates will be funded from cash on hand. Also as part of the Company's Return of Capital policy for the three months ended June 30, 2024, the Company expects to repurchase approximately $2.3 million of common stock between August 15, 2024, and September 30, 2024, subject to operating needs, market conditions, and other circumstances, such that the Dividend and Share Repurchases together equal 25% of net income for the three months ended June 30, 2024

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and related Securities and Exchange Commission (“SEC”) rules for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In our opinion, all adjustments consisting of normal recurring items, necessary for a fair statement of financial position, operating results and cash flows have been included in the unaudited interim condensed consolidated financial statements and related notes. The unaudited interim condensed consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements and related notes for the year ended December 31, 2023 included in our Annual Report on Form 20-F filed with the SEC on March 27, 2024 (the “2023 Annual Report”). The year-end condensed balance sheet data was derived from the audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. The results for the six months ended June 30, 2024, are not necessarily indicative of results for the year ending December 31, 2024, or any other future periods. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company, its subsidiaries and variable interest entities (“VIE”) for which the Company is a primary beneficiary and are also consolidated (please read Note 14—Variable Interest Entities for additional information). All intercompany accounts and transactions have been eliminated on consolidation. The results of operations are subject to seasonal and other fluctuations and are therefore not necessarily indicative of results that may otherwise be expected for the entire year. Management has evaluated the Company’s ability to continue as a going concern and considered the conditions and events that could raise substantial doubt about the Company’s ability to continue as a going concern within 12 months after these financial statements are issued. As part of the assessment, management has considered the following: •our current financial condition and liquidity sources, including current funds available and forecasted future cash flows; •the severity and duration of any world events and armed conflicts, including the Russian-Ukraine war, conflicts in the Israel-Gaza region and the potential for broader conflict in the Middle East involving Iran and other nations, and associated repercussions to supply and demand for oil and gas and the economy generally as well as possible effects of trade disruptions; •environmental regulations such as those affecting vessels' Energy Efficiency Existing Ship Index (“EEXI”); and •the total capital contributions required for the Terminal Expansion Project (as defined below). Management has determined that it is appropriate to continue to adopt the going concern basis in preparing the financial statements.
