Dorian LPG Ltd. (“Dorian”) was incorporated on July 1, 2013 under the laws of the Republic of the Marshall Islands, is headquartered in the United States and is engaged in the transportation of liquefied petroleum gas (“LPG”) worldwide through the ownership and operation of LPG tankers. Dorian LPG Ltd. and its subsidiaries (together “we,” “us,” “our,” or the “Company”) are focused on owning and operating very large gas carriers (“VLGCs”), each with a cargo carrying capacity of greater than 80,000 cbm. As of March 31, 2025, our fleet consists of twenty-five VLGCs, including one dual-fuel 84,000 cbm ECO-design VLGC (“Dual-fuel ECO VLGC”); nineteen fuel-efficient 84,000 cbm ECO-design VLGCs (“ECO VLGCs”); one 82,000 cbm modern VLGC; three time chartered-in dual fuel Panamax size VLGCs; and one time chartered-in ECO Panamax VLGC. On November 24, 2023, we entered into a shipbuilding contract for a newbuilding Very Large Gas Carrier / Ammonia Carrier (“VLGC/AC”) with a cargo carrying capacity of 93,000 cbm that can transport LPG or ammonia and is expected to be delivered from Hanwha Ocean Co. Ltd. in the second calendar quarter of 2026. We provide in-house commercial management services for all of our vessels, including our vessels deployed in the Helios Pool (defined below), which may also receive commercial management services from MOL Energia (defined below). Excluding our time chartered-in vessels, we provide in-house technical management services for all of our vessels, including our vessels deployed in the Helios Pool.

Sixteen of our ECO VLGCs, including one of our time chartered-in ECO-VLGCs, are fitted with exhaust gas cleaning systems (commonly referred to as “scrubbers”) to reduce sulfur emissions and, as of March 31, 2025, we have a contractual commitment to fabricate a scrubber on our newbuilding VLGC/AC. Additionally, one of the chartered-in dual-fuel Panamax size VLGCs is equipped with a shaft generator, which generates additional electricity that can be used to reduce fuel consumption and carbon emissions.

The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of Dorian LPG Ltd. and its subsidiaries.

On April 1, 2015, Dorian and MOL Energia Pte. Ltd. (“MOL Energia”), formerly known as Phoenix Tankers Pte. Ltd., began operations of Helios LPG Pool LLC (the “Helios Pool”), which entered into pool participation agreements for the purpose of establishing and operating, as charterer, under variable rate time charters to be entered into with owners or disponent owners of VLGCs, a commercial pool of VLGCs whereby revenues and expenses are shared. See Note 4 below for further description of the Helios Pool relationship.

Our subsidiaries, which are all wholly-owned and all are incorporated in Republic of the Marshall Islands (unless otherwise indicated below), as of March 31, 2025 are listed below.

(a)   Principles of consolidation:  The consolidated financial statements incorporate the financial statements of the Company and its wholly-owned subsidiaries. Income and expenses of subsidiaries acquired or disposed of during the period are included in the consolidated statements of operations from the effective date of acquisition and up to the effective date of disposal, as appropriate. All intercompany balances and transactions have been eliminated.

(b)   Use of estimates:  The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

(c)   Other comprehensive income/(loss):  We follow the accounting guidance relating to comprehensive income, which requires separate presentation of certain transactions that are recorded directly as components of shareholders’ equity. We have no other comprehensive income/(loss) and, accordingly, comprehensive income/(loss) equals net income/(loss) for the periods presented and thus we have not presented this in the consolidated statements of operations or in a separate statement.

(d)   Foreign currency translation:  Our functional currency is the U.S. Dollar. Foreign currency transactions are measured and recorded in the functional currency using the exchange rate in effect at the date of the transaction. As of balance sheet date, monetary assets and liabilities that are denominated in a currency other than the functional currency are adjusted to reflect the exchange rate at the balance sheet date and any gains or losses are included in the statements of operations. For the periods presented, we had no foreign currency derivative instruments.

(e)   Cash and cash equivalents:  We consider highly liquid investments with an original maturity of three months or less such as time deposits, certificates of deposit, U.S. government securities, and money market funds to be cash equivalents.

(f)   Short-term investments:  We consider short-term, highly-liquid time deposits placed with financial institutions, which are readily convertible into known amounts of cash with original maturities of more than three months, but less than 12 months at the time of purchase to be short-term investments.

(g)   Investment securities:  We hold investment securities that are classified as available-for-sale securities and are available to be sold in the future in response to our liquidity needs and asset-liability management strategies, among other considerations. Available-for-sale equity securities are reported at fair value, with unrealized gains and losses reported in in other gain/(loss), net on our consolidated statements of operations. Available-for-sale debt securities are reported at fair value, with unrealized gains and losses are reported in other comprehensive income/(loss). We had no unrealized gains and losses from debt securities reported in other comprehensive income/(loss) for the periods presented. We also hold equity securities that are recorded at cost that are evaluated for impairment periodically and, if needed, adjusted for other than temporary impairment. No impairment charges have been recorded for our equity securities, at cost.

(h)   Trade receivables, net and accrued revenues:  Trade receivables, net and accrued revenues, reflect receivables from vessel charters, net of an allowance for doubtful accounts. At each balance sheet date, all potentially uncollectible accounts are assessed individually for purposes of determining the appropriate provision for doubtful accounts. Provision for doubtful accounts for the periods presented was zero.

(i)   Due from related parties:  Due from related parties reflect receivables from the Helios Pool and other related parties. Distributions of earnings due from the Helios Pool are classified as current and working capital contributed to the Helios Pool is classified as non-current.

(j)   Inventories:  Inventories consist of bunkers on board the vessels when vessels are unemployed or are operating under voyage charters and lubricants and stores on board the vessels. Inventories are stated at lower of cost or net realizable value. Cost is determined by the first in, first out method. Net realizable value is the estimated selling price, less reasonably predictable costs of disposal and transportation.

(k)   Vessels, net and vessels under construction:  Vessels, net are stated at cost net of accumulated depreciation and impairment charges. The costs of the vessels acquired as part of a business acquisition are recorded at their fair value on the date of acquisition. The cost of vessels purchased consists of the contract price, less discounts, plus any direct expenses incurred upon acquisition, including improvements, commission paid, delivery expenses and other expenditures to prepare the vessel for her initial voyage. The initial purchase of LPG coolant for the refrigeration of cargo is also capitalized. Allocated interest costs incurred during construction are capitalized. Subsequent expenditures for conversions and major improvements, including scrubbers, are also capitalized when they appreciably extend the life, increase the earning capacity or improve the efficiency or safety of the vessels. Repairs and maintenance costs, including underwater inspection costs are expensed in the period incurred.

Costs capitalized to vessels during construction include shipyard costs, direct cost of project design and engineering, project site office administration costs, interest costs, and other such costs. Interest costs capitalized during the construction period of a vessel represent the amount which theoretically could have been avoided had we had not made installment payments on the vessel under construction.

(l)   Impairment of vessels:  We review our vessels “held and used” for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. When the estimate of future undiscounted cash flows, excluding interest charges, expected to be generated by the use of the vessel is less than its carrying amount, the asset is evaluated for an impairment loss. Measurement of the impairment loss is based on the fair value of the vessel.

(m)  Vessel depreciation:  Depreciation is computed using the straight-line method over the estimated useful life of the vessels, after considering the estimated salvage value. Each vessel’s salvage value is equal to the product of its lightweight tonnage and estimated scrap rate. Management estimates the useful life of its vessels to be 25 years from the date of initial delivery from the shipyard. Secondhand vessels are depreciated from the date of their acquisition through their remaining estimated useful life.

(n)   Drydocking and special survey costs:  Drydocking and special survey costs are accounted for under the deferral method whereby the actual costs incurred are deferred and are amortized on a straight-line basis over the period through the date the next survey is scheduled to become due. The classification societies provide guidelines applicable to LPG vessels relating to extended intervals for drydocking. Generally, we are required to drydock each of our vessels under 15 years of age every five years until they reach 15 years of age unless an extension of the drydocking to seven and one-half years is requested and granted by the classification society and the vessel is not older than 20 years of age. Costs deferred are limited to actual costs incurred at the yard and parts used in the drydocking or special survey. Costs deferred include expenditures incurred relating to shipyard costs, hull preparation and painting, inspection of hull structure and mechanical components, steelworks, machinery works, and electrical works. If a survey is performed prior to the scheduled date, the remaining unamortized balances are immediately written off. Unamortized balances of vessels that are sold are written-off and included in the calculation of the resulting gain or loss in the period of the vessel’s sale. The amortization charge is presented within Depreciation and amortization in the consolidated statements of operations.

(o)   Financing costs:  Financing costs incurred for obtaining new loans and credit facilities are deferred and amortized to interest expense over the respective term of the loan or credit facility using the effective interest rate method. Any unamortized balance of costs relating to loans/credit facilities repaid or refinanced is either expensed in the period the repayment or refinancing is made, or deferred and amortized over the terms of the respective credit facility, subject to the accounting guidance regarding Debt—Modifications and Extinguishments. Any unamortized balance of costs related to credit facilities repaid is expensed in the period. Any unamortized balance of costs relating to credit facilities refinanced is deferred and amortized over the term of the respective credit facility in the period the refinancing occurs, subject to the provisions of the accounting guidance relating to Debt—Modifications and Extinguishments. The unamortized financing costs are reflected as a reduction of Long-term debt—net of current portion and deferred financing fees in the consolidated balance sheet.

(p)   Restricted cash:  Restricted cash represents minimum liquidity to be maintained with certain banks under our borrowing arrangements, pledged cash deposits, and amounts held in escrow. The restricted cash is classified as non-current in the event that its obligation is not expected to be terminated within the next twelve months as it is long-term in nature.

(q)   Leases: Refer to Note 11 for a description of our operating lease expenses for the years ended March 31, 2025, 2024, and 2023 and to Note 20 for a description of commitments related to our leases as of March 31, 2025. The following is a description of our leasing arrangements.

Time charter-out contracts

Our time charter revenues are generated from our vessels being hired by a third-party charterer for a specified period in exchange for consideration, which is based on a monthly hire rate. The charterer has full discretion over the ports subject to compliance with the applicable charter party agreement and relevant laws. In a time charter contract, we are responsible for all the costs incurred for running the vessel such as crew costs, vessel insurance, repairs and maintenance, and lubricants. The charterer bears the voyage related costs such as bunker expenses, port charges and canal tolls during the hire period. The performance obligations in a time charter contract are satisfied on a straight-line basis over the term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to us. The charterer generally pays the charter hire monthly in advance. We determined that our time charter contracts are considered operating leases and therefore fall under the scope of the guidance because (i) the vessel is an identifiable asset, (ii) we do not have substantive substitution rights, and (iii) the charterer has the right to control the use of the vessel during the term of the contract and derives the economic benefits from such use. Under the guidance, we elected the practical expedient available to lessors to not separate the lease and non-lease components included in the time charter revenue because (i) the pattern of revenue recognition for the lease and non-lease components is the same as it is earned by the passage of time and (ii) the lease component, if accounted for separately, would be classified as an operating lease.

We record time charter revenues on a straight-line basis over the term of the charter as service is provided. Time charter revenues received in advance of the provision of charter service are recorded as deferred income and recognized when the charter service is rendered. Deferred income or accrued revenue also may result from straight-line revenue recognition in respect of charter agreements that provide for varying charter rates. Deferred income and accrued revenue amounts that will be recognized within the next twelve months are presented as current, with amounts to be recognized thereafter presented as non-current. Revenues earned through the profit-sharing arrangements in the time charters represent contingent rental revenues that are recognized when earned and amounts are reasonably assured based on estimates provided by the charterer.

Net pool revenues—related party

As from April 1, 2015, we began operation of a pool. Net pool revenues—related party for each vessel in the pool is determined in accordance with the profit-sharing terms specified within the pool agreement. In particular, the pool manager calculates the net pool revenues using gross revenues less voyage expenses of all the pool vessels and less the general and administrative expenses of the pool and distributes the net pool revenues as time charter hire to participants based on:

pool points (vessel attributes such as cargo carrying capacity, fuel consumption, and speed are taken into consideration); and

number of days the vessel participated in the pool in the period.

We recognize net pool revenues—related party on a monthly basis, when the vessel has participated in the pool during the period and the amount of net pool revenues for the month can be estimated reliably. Revenue generated from the pool is accounted for as revenue from operating leases.

Time charter-in contracts

Our time charter-in contracts relate to the charter-in activity of vessels from third parties for a specified period of time in exchange for consideration, which is based on a monthly hire rate. We elected the practical expedient of the guidance that allows for contracts with an initial lease term of 12 months or less to be excluded from the operating lease right-of-use assets and lease liabilities recognized on our consolidated balance sheets.

Under the guidance, we elected the practical expedients available to lessees to not separate the lease and non-lease components included in the charter hire expense because (i) the pattern of revenue recognition for the lease and non-lease components is the same as it is earned by the passage of time and (ii) the lease component, if

accounted for separately, would be classified as an operating lease. We elected not to separate the lease and non-lease components included in charter hire expense, but to recognize operating lease expense as a combined single lease component for all time charter-in contracts.

Office leases

We carried forward our historical assessments of (i) whether contracts are or contain leases, (ii) lease classifications, and (iii) initial direct costs. For leases with terms greater than 12 months, we record the related right-of-use asset and lease liability as the present value of fixed lease payments over the lease term. For leases that do not provide a readily determinable discount rate, we use our incremental borrowing rate to discount lease payments to present value.

Under the guidance, we elected the practical expedients available to lessees to not separate the lease and non-lease components included in the office lease expense but to recognize operating lease expense as a combined single lease component for all office lease contracts because (i) the pattern of revenue recognition for the lease and non-lease components is the same as it is earned by the passage of time and (ii) the lease component, if accounted for separately, would be classified as an operating lease.

(r)

Voyage charter revenues:  In a voyage charter contract, a charterer hires a vessel to transport a specific agreed-upon cargo for a single voyage, which may contain multiple load ports and discharge ports. The consideration in such a contract is determined on the basis of a freight rate per metric ton of cargo carried or occasionally on a lump sum basis. The charter party generally has a minimum amount of cargo. The charterer is liable for any short loading of cargo or "dead" freight. The contract generally has standard payment terms of freight paid within three to five days after completion of loading. The contract generally has a "demurrage" or "despatch" clause. As per this clause, the charterer reimburses us for any potential delays exceeding the allowed laytime as per the charter party clause at the ports visited which is recorded as demurrage revenue. Conversely, the charterer is given credit if the loading/discharging activities happen within the allowed laytime, known as despatch, resulting in a reduction in revenue. The voyage contracts generally have variable consideration in the form of demurrage or despatch. Revenue from voyage charters is recognized when (i) the parties to the contract have approved the contract in the form of a written charter agreement and are committed to perform their respective obligations, (ii) we can identify each party’s rights regarding the services to be transferred, (iii) we can identify the payment terms for the services to be transferred, (iv) the charter agreement has commercial substance (that is, the risk, timing, or amount of our future cash flows is expected to change as a result of the contract) and (v) it is probable that we will collect substantially all of the consideration to which we will be entitled in exchange for the services that will be transferred to the charterer.

Voyage charter agreements do not contain a lease and are therefore considered service contracts that fall under the provisions of Accounting Standard Codification (“ASC”) 606 Revenue from Contracts with Customers. Voyage contracts are considered service contracts which fall under the provisions of ASC 606 because we retain control over the operations of the vessel, including directing the routes taken and vessel speed. We determined that a voyage charter agreement includes a single performance obligation, which is to provide the charterer with an integrated transportation service within a specified time period. In addition, we have concluded that a contract for a voyage charter meets the criteria to recognize revenue over time because the charterer simultaneously receives and consumes the benefits of our performance as the voyage progresses and therefore revenues are recognized on a pro rata basis over the duration of the voyage determined on a load-to-discharge port basis. In the event a vessel is acquired or sold while a voyage is in progress, the revenue recognized is based on an allocation formula agreed between the buyer and the seller. Demurrage is recognized when earned and collection is reasonably assured and despatch expense is recognized as incurred. Voyage charter revenue relating to voyages in progress as of the balance sheet date are accrued and presented in Trade receivables and accrued revenue in the consolidated balance sheet.

(s)   Voyage expenses:  Voyage expenses are expensed as incurred, except for expenses during the ballast portion of the voyage (period between the contract date and the date of the vessel’s arrival to the load port). Any expenses incurred during the ballast portion of the voyage such as bunker expenses, canal tolls and port expenses are

deferred and are recognized on a straight-line basis, in voyage expenses, over the voyage duration as we satisfy the performance obligations under the contract provided these costs are (1) incurred to fulfill a contract that we can specifically identify, (2) able to generate or enhance resources of the company that will be used to satisfy performance of the terms of the contract, and (3) expected to be recovered from the charterer. These costs are considered contract fulfillment costs because the costs are direct costs related to the performance of the contract and are expected to be recovered. Voyage expenses also consist of bunker expenses, canal tolls and port expenses incurred for vessels traveling to drydock and to be delivered to new owners in the case of a vessel sale are expensed as incurred.

(t)   Commissions:  Charter hire commissions to brokers or managers, if any, are deferred and amortized over the related charter period and are included in Voyage expenses.

(u)   Charter hire expenses:  Charter hire expenses in relation to vessels that we may occasionally charter in from third parties are recorded on a straight-line basis over the term of the charter as service is provided. Charter hire expenses paid in advance of the provision of charter service are recorded as a current asset and recognized when the charter service is rendered. Deferred expenses also may result from straight-line recognition in respect of charter agreements that provide for varying charter rates. Deferred expense amounts that will be recognized within the next twelve months are presented as current, with amounts to be recognized thereafter presented as noncurrent.

(v)  Vessel operating expenses:  Vessel operating expenses are accounted for as incurred on the accrual basis. Vessel operating expenses include crew wages and related costs, the cost of vessel insurance, expenses relating to repairs and maintenance, the cost of spares and consumable stores and other miscellaneous expenses.

(w)   Stock-based compensation: Stock-based compensation expense for grants to officers, directors and employees is measured at the grant date based on the estimated fair value of the awards and is recognized over the vesting period. We account for restricted stock award forfeitures upon occurrence.

(x)   Stock repurchases:  We record the repurchase of our shares of common stock at cost based on the settlement date of the transaction. These shares are classified as treasury stock unless canceled, which is a reduction in shareholders’ equity. Treasury shares are included in authorized and issued shares, but excluded from outstanding shares.

(y)   Dividends:  Dividends are recognized in the consolidated statements of shareholders’ equity when they are declared by our board of directors (“Board of Directors”).

(z)

Segment reporting:  Each of our vessels serves the same type of customer, has similar operations and maintenance requirements, operates in the same regulatory environment, and are subject to similar economic characteristics. Based on this, we have determined that our Company operates in one reportable segment, the international transportation of liquid petroleum gas with its fleet of vessels. Furthermore, when we charter a vessel to a charterer, the charterer is free to trade the vessel worldwide and, as a result, the disclosure of geographic information is impracticable. See Note 3 below for further disclosure related to segment reporting. Our Chief Executive Officer is the chief operating decision maker (“CODM”) and evaluates the operating results of the Company using the consolidated revenues and expenses as noted on the face of the consolidated statements of operations. The CODM assesses performance for the vessel operations segment and decides how to allocate resources based on consolidated net income and consolidated operating income.

(aa)  Derivative instruments:  All derivatives are stated at their fair value, as either a derivative asset or a liability. The fair value of the interest rate derivatives is based on a discounted cash flow analysis and their fair value changes are recognized in current period earnings. Settlements of derivative instruments are included in cash flows from operating activities in the consolidated statements of cash flows. When the derivatives do qualify for hedge accounting, depending upon the nature of the hedge, changes in fair value of the derivatives are either recognized in current period earnings or in other comprehensive income/(loss) (effective portion) until the hedged

item is recognized in the consolidated statements of operations. For the periods presented, no derivatives were accounted for as accounting hedges.

(ab)  Fair value of financial instruments:  In accordance with the requirements of accounting guidance relating to Fair Value Measurements, the Company classifies and discloses its assets and liabilities carried at fair value in one of the following three categories:

Level 1:

Quoted market prices in active markets for identical assets or liabilities.

Level 2:

Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3:

Unobservable inputs that are not corroborated by market data.

(ac)  Recent accounting pronouncements:

In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-03, Disaggregation of Income Statement Expenses (“ASU 2024-03”), which requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements with the objective to address longstanding requests from investors to provide more detailed information about expenses presented on the face of the income statement. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within the fiscal years beginning after December 15, 2027 with early adoption permitted. The amendments are to be applied either prospectively to financial statements issued for the reporting periods after the effective date or retrospectively to any or all prior periods presented in the financial statements. We are currently evaluating the impact of the adoption of ASU 2024-03 on our consolidated financial statements and related disclosures.

We have considered all other recent accounting pronouncements issued and believe that none will have a material effect on our financial statements.

Dorian (Hellas) S.A.

Dorian (Hellas) S.A. (“DHSA”) formerly provided technical, crew, commercial management, insurance and accounting services to our vessels and had agreements to outsource certain of these services to Eagle Ocean Transport Inc. (“Eagle Ocean Transport”), which is 100% owned by Mr. John C. Hadjipateras, our Chairman, President and Chief Executive Officer.

Dorian LPG (USA) LLC and its subsidiaries entered into an agreement with DHSA, retroactive to July 2014 and superseding an agreement between Dorian LPG (UK) Ltd. and DHSA, for the provision by Dorian LPG (USA) LLC and its subsidiaries of certain chartering and marine operation services to DHSA, for which income was earned and included in “Other income-related parties” totaling $0.1 million for each of the years ended March 31, 2025, 2024 and 2023. As of March 31, 2025 and 2024, there was nothing due from DHSA.

Helios LPG Pool LLC (“Helios Pool”)

On April 1, 2015, Dorian and MOL Energia began operations of the Helios Pool, which entered into pool participation agreements for the purpose of establishing and operating, as charterer, under variable rate time charters to be entered into with owners or disponent owners of VLGCs, a commercial pool of VLGCs whereby revenues and expenses are shared. We hold a 50% interest in the Helios Pool as a joint venture with MOL Energia and all significant rights and obligations are equally shared by both parties. All profits of the Helios Pool are distributed to the pool participants based on pool points assigned to each vessel as variable charter hire and, as a result, there are no profits available to the equity investors as a share of equity. We have determined that the Helios Pool is a variable interest entity as it does not have sufficient equity at risk. We do not consolidate the Helios Pool because we are not the primary beneficiary and do not have a controlling financial interest. In consideration of Accounting Standards Codification (“ASC”) 810-10-50-4e, the significant factors considered and judgments made in determining that the power to direct the activities of the Helios Pool that most significantly impact the entity’s economic performance are shared, in that all significant performance activities which relate to approval of pool policies and strategies related to pool customers and the marketing of the pool for the procurement of customers for the pool vessels, addition of new pool vessels and the pool cost management, require unanimous board consent from a board consisting of two members from each joint venture investor. Further, in accordance with the guidance in ASC 810-10-25-38D, the Company and MOL Energia are not related parties as defined in ASC 850 nor are they de facto agents pursuant to ASC 810-10, the power over the significant activities of the Helios Pool is shared, and no party is the primary beneficiary in the Helios Pool, or has a controlling financial interest. As of March 31, 2025, the Helios Pool operated twenty-nine VLGCs, including twenty-five vessels from our fleet (including four vessels time chartered-in from unrelated parties), three MOL Energia vessels and one time chartered-in vessel.

As of March 31, 2025, we had net receivables from the Helios Pool of $74.4 million (net of an amount due to Helios Pool of less than $0.1 million which is reflected under “Due to related Parties”), including $26.4 million of working capital contributed for the operation of our vessels in the pool. As of March 31, 2024, we had receivables from the Helios Pool of $77.6 million (net of an amount due to Helios Pool of $0.1 million which is reflected under “Due to related Parties”), including $25.3 million of working capital contributed for the operation of our vessels in the pool. Our maximum exposure to losses from the pool as of March 31, 2025 is limited to the receivables from the pool. The Helios Pool does not have any third-party debt obligations. The Helios Pool has entered into commercial management agreements with each of Dorian LPG (UK) Ltd. and MOL Energia as commercial managers and has appointed both commercial managers as the exclusive commercial managers of pool vessels. Dorian LPG (DK) ApS has assumed the responsibilities of Dorian LPG (UK) Ltd. under these commercial management agreements with the consolidation of our London, United Kingdom operations into our Copenhagen, Denmark office. Fees for commercial management services provided by Dorian LPG (DK) ApS are included in “Other income-related parties” in the consolidated statement of operations and were $2.5 million, $2.5 million and $2.2 million for the years ended March 31, 2025, 2024 and 2023, respectively. Additionally, we received a fixed reimbursement of expenses such as costs for security guards and war risk insurance for vessels operating in high-risk areas from the Helios Pool, for which we earned $1.2 million, $0.8 million and $1.4 million for the years ended March 31, 2025, 2024 and 2023 respectively, and are included in “Other revenues, net” in the consolidated statements of operations.

Through our vessel owning subsidiaries, we have chartered vessels to the Helios Pool during the years ended March 31, 2025, 2024 and 2023. The time charter revenue from the Helios Pool is variable depending upon the net results of the pool, available days and pool points for each vessel. The Helios Pool enters into voyage and time charters with external parties and receives freight and related revenue and, where applicable, incurs voyage costs such as bunkers, port costs and commissions. At the end of each month, the Helios Pool calculates net pool revenues using gross revenues, less voyage expenses of all pool vessels, less fixed time charter hire for any time chartered-in vessels, less the general and administrative expenses of the pool. Net pool revenues, less any amounts required for working capital of the Helios Pool, are distributed, to the extent they have been collected from third-party customers of the Helios Pool, as variable rate time charter hire for the relevant vessel to participants based on pool points (vessel attributes such as cargo carrying capacity, fuel consumption, and speed are taken into consideration) and number of days the vessel participated in the pool in the period. We recognize net pool revenues on a monthly basis, when each relevant vessel has participated in the pool during the period and the amount of net pool revenues for the month can be estimated reliably. Revenue earned from the Helios Pool is presented in Note 15.

10. Long-Term Debt

Description of our Debt Obligations

2023 A&R Debt Facility

On July 29, 2022, we entered into a $260.0 million debt financing facility (the “2022 Debt Facility”) with Crédit Agricole Corporate and Investment Bank (“CACIB”), ING Bank N.V. (“ING”), Skandinaviska Enskilda Banken AB (publ) (“SEB”), BNP Paribas (“BNP”), and Danish Ship Finance A/S (“DSF”) to refinance then current indebtedness.

On December 22, 2023, we entered into an amended and restated debt financing facility (the “2023 A&R Debt Facility”) with CACIB, ING, SEB, BNP, and DSF to amend and restate the 2022 Debt Facility. The 2023 A&R Debt Facility consists of (i) a term loan facility in an aggregate original principal amount of $240.0 million, of which $215.0 million remained outstanding on the date of the agreement, (ii) a revolving credit facility in an aggregate principal amount of up to $50.0 million (previously $20.0 million) and (iii) a new, uncommitted accordion term loan facility in an aggregate principal amount of up to $100.0 million. The 2023 A&R Debt Facility matures on August 4, 2029, with drawn amounts thereunder accruing interest at a rate of SOFR plus a margin ranging between 2.05% and 2.15% depending on the ratio of outstanding debt under the facility to the value of the vessels secured under this facility, plus or minus a sustainability pricing adjustment of 0.05%. The undrawn revolving credit facility accrues interest at a rate equal to 0.40% of the margin.

The 2023 A&R Debt Facility is secured by, among other things, (i) first priority Bahamian mortgages on the vessels financed, (ii) first priority assignments of all of the financed vessels’ mandatory insurances and earnings and management agreements; (iii) first priority pledge in respect of all limited liability company interests of the borrowers and vessel-owning guarantors; (iv) first priority charter assignments of all of the financed vessels’ long-term charters to non-Helios LPG Pool parties with an original tenor greater than 13 months; and (v) a guaranty by the Company guaranteeing the obligations of the borrower and other guarantors under the facility agreement. The 2023 A&R Debt Facility further provides that the facility is to be secured by assignments of the borrower’s rights under any hedging contracts in connection with the facility, but such assignments have not been entered into at this time.

The 2023 A&R Debt Facility also contains customary covenants that require us to maintain adequate insurance coverage and to properly maintain the vessels. The loan facility includes customary events of default, including those relating to a failure to pay principal or interest, breaches of covenants, representations and warranties, a cross-default to certain other debt obligations and non-compliance with security documents, and customary restrictions on paying dividends if an event of default has occurred and is continuing, or if an event of default would result therefrom.

We are required to comply with the following financial covenants from the 2023 A&R Debt Facility, calculated on a consolidated basis, determined and defined according to the provisions of the loan agreement and its amendments:

The ratio of current assets and long-term restricted cash divided by current liabilities, excluding current portion of long-term debt, shall always be greater than 1.00;
Maintain minimum shareholders’ equity at all times equal to the aggregate of $400 million;
The ratio of consolidated net debt to consolidated total capitalization shall not exceed 0.60 to 1.00;
Fair market value of the mortgaged ships plus any additional security over the outstanding loan balance shall not be less than 145%; and
Minimum liquidity covenant of the greater of (i) $27.5 million and (ii) 5% of consolidated interest-bearing debt.

We were in compliance with all financial covenants as of March 31, 2025.

BALCAP Facility

On December 29, 2021, we completed the refinancing of our indebtedness secured by the VLGCs Constellation and Commander through a new loan facility entered into between, among others, Constellation LPG Transport LLC and Commander LPG Transport LLC, as borrowers, and Banc of America Leasing & Capital, LLC, Pacific Western Bank, Raymond James Bank, a Florida chartered bank and City National Bank of Florida, as lenders (“BALCAP Facility”). The financing has a 3.78% fixed interest rate, a term of five years, a face amount of $83.4 million, and a fixed monthly, mortgage-style payment of $0.9 million with a balloon payment of $44.1 million in December 2026. We received $34.9 million of net cash proceeds after repayment of the then outstanding principal amount of debt related to those vessels and fees and expenses related to the refinancing transaction.

The BALCAP Facility is secured by, among other things, (i) first priority Bahamian mortgages on the vessels financed and deeds of covenant collateral thereto; (ii) first priority assignments of all of the financed vessels’ insurances, earnings and requisition compensation; (iii) first priority security interests in respect of all of the equity interests of the borrowers; (iv) subordination of the rights of any technical ship manager in the proceeds of any insurances of the financed vessels; (v) an assignment by each borrower of any deposit account opened by it in accordance with the facility; and (vi) a guaranty by the Company guaranteeing the obligations of the borrowers under the facility agreement. In addition, we must ensure that the aggregate fair market value of Constellation and Commander is at least 125% of the outstanding principal balance of the loan under the BALCAP Facility.

The corporate financial covenants related to the BALCAP Facility are identical to those in the 2023 A&R Debt Facility. We were in compliance with all financial covenants as of March 31, 2025.

Japanese Financing Arrangements

All of our Japanese financing arrangements (described below) are secured by, among other things, (i) the mortgages on the vessels financed, (ii) first priority assignments of all of the financed vessels’ mandatory insurances; and (iii) a guaranty by the Company guaranteeing the obligations of each borrower.

Corsair Japanese Financing

On November 7, 2017, we refinanced a 2014-built VLGC, Corsair, pursuant to a memorandum of agreement and a bareboat charter agreement (“Corsair Japanese Financing”). In connection therewith, we transferred Corsair to the buyer for $65.0 million and, as part of the agreement, Corsair LPG Transport LLC, our wholly-owned subsidiary, bareboat chartered the vessel back for a period of 12 years, with purchase options from the end of year 2 onwards through a mandatory buyout by 2029. We continue to technically manage, commercially charter, and operate Corsair. We received $52.0 million in cash as part of the transaction with $13.0 million to be retained by the buyer as a deposit (the “Corsair Deposit”), which can be used by us towards the repurchase of the vessel either pursuant to an early buyout option or at the end of the 12-year bareboat charter term. The refinancing proceeds of $52.0 million were used to prepay $30.1 million of the then outstanding principal amount of debt related to Corsair. The remaining proceeds were used to pay legal fees associated with this transaction and for general corporate purposes. The Corsair Japanese Financing is treated as a financing transaction and the VLGC continues to be recorded as an asset on our balance sheet. This debt financing has a fixed interest rate of 4.9%, not including financing costs of $0.1 million, monthly broker commission fees of 1.25% over the 12-year term on interest and principal payments made, broker commission fees of 1% of the purchase option price excluding the Corsair Deposit, and a monthly fixed straight-line principal obligation of approximately $0.3 million over the 12-year term with a balloon payment of $13.0 million.

Cresques Japanese Financing

On April 21, 2020, we prepaid $28.5 million of the then outstanding principal amount of debt related to Cresques using cash on hand prior to the closing of the Cresques Japanese Financing (defined below). On April 23, 2020, we refinanced a 2015-built VLGC, Cresques, pursuant to a memorandum of agreement and a bareboat charter agreement (“Cresques Japanese Financing”). In connection therewith, we transferred Cresques to the buyer for $71.5 million and, as part of the agreement, Dorian Dubai LPG Transport LLC, our wholly-owned subsidiary, bareboat chartered the vessel back for a period of 12 years, with purchase options from the end of year 3 onwards through a mandatory buyout by 2032. We continue to technically manage, commercially charter, and operate Cresques. We received $52.5 million in cash as part of the transaction with $19.0 million to be retained by the buyer as a deposit (the “Cresques Deposit”), which can be used by us towards the repurchase of the vessel either pursuant to an early buyout option or at the end of the 12-year bareboat charter term. This transaction is treated as a financing transaction and Cresques continues to be recorded as an asset on our balance sheet. This debt financing had a floating interest rate of one-month LIBOR plus a margin of 2.5%, monthly broker commission fees of 1.25% over the 12-year term on interest and principal payments made, broker commission fees of 0.5% payable on the remaining debt outstanding at the time of the repurchase of the Cresques, and a monthly fixed straight-line principal obligation of $0.3 million over the 12-year term with a balloon payment of $11.5 million.

On March 13, 2023, we agreed to an addendum to the Cresques Japanese Financing’s bareboat charter agreement that became effective on March 23, 2023. Terms of the addendum include a switch from one-month LIBOR as the floating interest rate to one-month SOFR, an increase of 0.11448%, reflecting a credit adjustment spread for the switch from unsecured LIBOR to secured SOFR.

On March 20, 2023, we voluntarily prepaid $15.0 million of the Cresques Japanese Financing’s then outstanding principal. Fees for the voluntary prepayment totaled $0.1 million and, following the prepayment, monthly principal payments have been reduced to $0.1 million.

On June 12, 2023, we agreed to an addendum to the Cresques Japanese Financing’s bareboat charter agreement that became effective on June 20, 2023. The terms of the addendum include a switch from a floating interest rate of one-month SOFR plus a margin to a fixed interest rate of 6.55%.

Cratis Japanese Financing

On March 18, 2022, we refinanced a 2015-built VLGC, Cratis, pursuant to a memorandum of agreement and a bareboat charter agreement. In connection therewith, we transferred the Cratis to the buyer for $70.0 million and, as part of the agreement, Dorian Geneva LPG Transport LLC, our wholly-owned subsidiary, bareboat chartered the vessel back for a period of 9 years, with purchase options from the end of year 3 onwards through a mandatory buyout by 2031. We continue to technically manage, commercially charter, and operate Cratis. We received $50.0 million in cash as part of the transaction with $20.0 million to be retained by the buyer as a deposit (the “Cratis Deposit”), which can be used by us towards the repurchase of the vessel either pursuant to an early buyout option or at the end of the 9-year bareboat charter term. The refinancing proceeds of $50.0 million were used to prepay $25.1 million of the then outstanding principal amount of debt related to Cratis. The remaining proceeds were, or will be, used to pay legal fees associated with this transaction and for general corporate purposes. This transaction is treated as a financing transaction and Cratis continues to be recorded as an asset on our balance sheet. This debt financing has a fixed interest rate of 4.1%, not including financing costs of $0.3 million, monthly broker commission fees of 1.25% over the 9-year term on interest and principal payments made, broker commission fees of 0.5% of an exercised purchase option excluding the Cratis Deposit, and a monthly fixed straight-line principal obligation of approximately $0.3 million over the 9-year term with a balloon payment of $13.3 million.

Copernicus Japanese Financing

On March 18, 2022, we refinanced a 2015-built VLGC, Copernicus, pursuant to a memorandum of agreement and a bareboat charter agreement. In connection therewith, we transferred Copernicus to the buyer for $70.0 million and, as part of the agreement, Dorian Tokyo LPG Transport LLC, our wholly-owned subsidiary, bareboat chartered the vessel back for a period of 9 years, with purchase options from the end of year 3 onwards through a mandatory buyout by 2031.

We continue to technically manage, commercially charter, and operate Copernicus. We received $50.0 million in cash as part of the transaction with $20.0 million to be retained by the buyer as a deposit (the “Copernicus Deposit”), which can be used by us towards the repurchase of the vessel either pursuant to an early buyout option or at the end of the 9-year bareboat charter term. The refinancing proceeds of $50.0 million were used to prepay $25.3 million of the then outstanding principal amount of debt related to Copernicus. The remaining proceeds were, or will be, used to pay legal fees associated with this transaction and for general corporate purposes. This transaction is treated as a financing transaction and Copernicus continues to be recorded as an asset on our balance sheet. This debt financing has a fixed interest rate of 4.1%, not including financing costs of $0.3 million, monthly broker commission fees of 1.25% over the 9-year term on interest and principal payments made, broker commission fees of 0.5% of an exercised purchase option excluding the Copernicus Deposit, and a monthly fixed straight-line principal obligation of approximately $0.3 million over the 9-year term with a balloon payment of $13.3 million.

Chaparral Japanese Financing

On March 29, 2022, we refinanced a 2015-built VLGC, Chaparral, pursuant to a memorandum of agreement and a bareboat charter agreement. In connection therewith, we transferred Chaparral to the buyer for $64.9 million and, as part of the agreement, Dorian Cape Town LPG Transport LLC, our wholly-owned subsidiary, bareboat chartered the vessel back for a period of 7 years plus 3 option years with no purchase obligation and purchase options beginning from the end of year 5 onwards. We continue to technically manage, commercially charter, and operate Chaparral. The refinancing proceeds of $64.9 million were used to prepay $24.0 million of the then outstanding principal amount of debt related to Chaparral. The remaining proceeds were, or will be, used to pay legal fees associated with this transaction and for general corporate purposes. This transaction is treated as a financing transaction and Chaparral continues to be recorded as an asset on our balance sheet. The agreement for this debt financing does not have a stated interest rate and, therefore, we have calculated an imputed interest rate of 5.3% for the 7-year period, not including financing costs of $0.1 million, and a monthly fixed straight-line mortgage-style obligation of approximately $0.5 million over the 7-year period with a purchase option of $45.8 million on the seventh anniversary.

Caravelle Japanese Financing

On March 31, 2022, we refinanced a 2016-built VLGC, Caravelle, pursuant to a memorandum of agreement and a bareboat charter agreement. In connection therewith, we transferred Caravelle to the buyer for $71.5 million and, as part of the agreement, Dorian Exporter LPG Transport LLC, our wholly-owned subsidiary, bareboat chartered the vessel back for a period of 10 years, with purchase options from the end of year 3 onwards through a mandatory buyout by 2032. We continue to technically manage, commercially charter, and operate Caravelle. We received $50.0 million in cash as part of the transaction with $21.5 million to be retained by the buyer as a deposit (the “Caravelle Deposit”), which can be used by us towards the repurchase of the vessel either pursuant to an early buyout option or at the end of the 10-year bareboat charter term. The refinancing proceeds of $50.0 million were used to prepay $24.8 million of the then outstanding principal amount of debt related to Caravelle. The remaining proceeds were, or will be, used to pay legal fees associated with this transaction and for general corporate purposes. This transaction is treated as a financing transaction and Caravelle continues to be recorded as an asset on our balance sheet. This debt financing has a fixed interest rate of 4.2%, not including financing costs of $0.3 million, monthly broker commission fees of 1.25% over the 10-year term on interest and principal payments made, broker commission fees of 0.5% of an exercised purchase option excluding the Caravelle Deposit, and a monthly fixed straight-line principal obligation of approximately $0.3 million over the 10-year term with a balloon payment of $14.0 million.

Cougar Japanese Financing

On May 19, 2022, we refinanced a 2015-built VLGC, Cougar, pursuant to a memorandum of agreement and a bareboat charter agreement. In connection therewith, we transferred Cougar to the buyer for $70.0 million and, as part of the agreement, Dorian Shanghai LPG Transport LLC, our wholly-owned subsidiary, bareboat chartered the vessel back for a period of 10 years, with purchase options from the end of year 3 onwards through a mandatory buyout by 2032. We continue to technically manage, commercially charter, and operate Cougar. We received $50.0 million in cash as part of the transaction with $20.0 million to be retained by the buyer as a deposit (the “Cougar Deposit”), which can be used by us towards the repurchase of the vessel either pursuant to an early buyout option or at the end of the 10-year bareboat charter term. The refinancing proceeds of $50.0 million were used to prepay $20.0 million of the then outstanding principal

amount of debt related to Cougar. The remaining proceeds will be used to pay legal fees associated with this transaction and for general corporate purposes. This transaction will be treated as a financing transaction and Cougar will continue to be recorded as an asset on our balance sheet. This debt financing has a floating interest rate of three-month SOFR plus a margin of 2.45%, not including financing costs of $0.4 million, monthly broker commission fees of 1.25% over the 10-year term on interest and principal payments made, broker commission fees of 0.5% on the exercise of the purchase option or obligation excluding the Cougar Deposit, and a quarterly fixed straight-line principal obligation of approximately $0.9 million over the 10-year term with a balloon payment of $14.0 million.

On July 21, 2023, we agreed to an addendum to the Cougar Japanese Financing’s bareboat charter agreement that became effective on August 21, 2023. The terms of the addendum include a switch from a floating interest rate of three-month SOFR plus a margin to a fixed interest rate of 6.34%.

Captain Markos Dual-Fuel Japanese Financing

On March 31, 2023, we financed a 2023-built Dual-fuel ECO VLGC, Captain Markos, from the shipyard pursuant to a memorandum of agreement and a bareboat charter agreement. Similar to our previous Japanese financings, this transaction is treated as a financing transaction and Captain Markos is recorded as an asset on our balance sheet. Prior to the delivery of the vessel, we paid $25.0 million in cash and, upon delivery, entered into a $56 million bareboat charter financing arrangement. This debt financing has a floating interest rate of one-month SOFR plus a credit adjustment spread of 0.1148% (reflecting the difference between unsecured LIBOR and secured SOFR) and a margin of 2.475%, monthly broker commission fees of 1.25% over the 13-year term on interest and principal payments made, broker commission fees of 1.0% payable on the remaining debt outstanding at the time of the repurchase of Captain Markos, and a monthly fixed straight-line principal obligation of $0.210 million until February 29, 2028 and of $0.250 million from March 31, 2028 through the remainder of bareboat charter period with a balloon payment of $19.4 million. We have early buyout options beginning March 31, 2028 with a purchase obligation on March 31, 2036.

On June 12, 2023, we agreed to an addendum to the Captain Markos Dual-Fuel Japanese Financing’s bareboat charter agreement that became effective on June 30, 2023.

On June 7, 2024, we issued 2 million shares to the public at a price of $44.50 per share with proceeds totaling $89.0 million, less (i) $2.225 per share, or $4.5 million, of underwriting discounts and commissions, and (ii) $0.1 million of legal and other offering costs.

On February 2, 2022, our Board of Directors authorized the repurchase of up to $100.0 million of our common shares (the “2022 Common Share Repurchase Authority”). Under this authorization, when in force, purchases were and may be made at our discretion in the form of open market repurchase programs, privately negotiated transactions, accelerated share repurchase programs or a combination of these methods. The actual amount and timing of share repurchases are subject to capital availability, our determination that share repurchases are in the best interest of our shareholders, and market conditions. As of March 31, 2025, our total purchases under the 2022 Common Share Repurchase Authority totaled 161,500 shares for an aggregate consideration of $3.8 million. We are not obligated to make any common share repurchases.

14. Stock-Based Compensation Plans

In April 2014, we adopted an equity incentive plan, which we refer to as the Equity Incentive Plan, under which we expect that directors, officers, and employees (including any prospective officer or employee) of the Company and its subsidiaries and affiliates, and consultants and service providers to (including persons who are employed by or provide services to any entity that is itself a consultant or service provider to) the Company and its subsidiaries and affiliates, as well as entities wholly-owned or generally exclusively controlled by such persons, may be eligible to receive non-qualified stock options, stock appreciation rights, stock awards, restricted stock units and performance compensation awards that the plan administrator determines are consistent with the purposes of the plan and the interests of the Company. At that time, we reserved 2,850,000 of our common shares for issuance under the Equity Incentive Plan, subject to adjustment for changes in capitalization as provided in the Equity Incentive Plan in April 2014. In October 2021, our shareholders approved an amendment to the Equity Incentive Plan to increase the reserve of our common shares for issuance by 2,015,000. The plan is administered by our compensation committee.

During the year ended March 31, 2025, we granted to certain of our officers and employees an aggregate of 231,150 shares of restricted stock vesting ratably on the grant date and on the first, and second anniversary of that date, 16,000 shares of restricted stock vesting on the grant date and 48,960 restricted stock units vesting ratably on the grant date and on the first and second anniversaries of the grant date.

During the year ended March 31, 2024, we granted to certain of our officers and employees an aggregate of 229,750 shares of restricted stock vesting ratably on the grant date and on the first, second, and third anniversary of that date, 35,000 shares of restricted stock vesting ratably on the grant date and on the first, and second anniversary of that date 45,500 restricted stock units vesting ratably on the grant date and on the first and second anniversaries of the grant date.

During the year ended March 31, 2023, we granted to certain of our officers and employees an aggregate of 47,750 shares of restricted stock vesting ratably on the grant date and on the first, second, and third anniversary of that date, 53,100 restricted stock units vesting ratably on the grant date and on the first and second anniversaries of the grant date, and 165,500 shares of restricted stock vesting ratably on the grant date and on the first and second anniversary of that date. The final tranche of restricted stock granted to certain of our named executive officers shall vest when, and only if, the volume weighted average price of our common shares over any consecutive 15-day period prior to the final business day of the tenth fiscal quarter following the grant date equals or exceeds, 95% of the book value of one of our shares. The shares of restricted stock and restricted stock units were valued at their grant date fair market value and are expensed on a straight-line basis over the respective vesting periods.

During the years ended March 31, 2025, 2024, and 2023, we granted 29,741, 31,400, and 34,695, shares of stock, respectively, to our non-executive directors, which were valued and expensed at their grant date fair market value.

Our stock-based compensation expense was $10.4 million, $8.3 million and $4.3 million for the years ended March 31, 2025, 2024, and 2023, respectively, and is included within general and administrative expenses in our consolidated statements of operations. Unrecognized compensation cost as of March 31, 2025 was $5.6 million and the expense will be recognized over a remaining weighted average life of 1.19 years.

A summary of the activity of our restricted shares as of March 31, 2025 and 2024 and changes during the years ended March 31, 2025 and 2024, are as follows:

19. Income Taxes

Dorian LPG Ltd. and its vessel-owning subsidiaries are incorporated in the Marshall Islands and under the laws of the Marshall Islands, are not subject to tax on income or capital gains and no Marshall Islands withholding tax will be imposed on dividends paid by the Company to its shareholders. Dorian LPG Ltd. and its vessel-owning subsidiaries are also subject to United States federal income taxation in respect of shipping income, unless exempt from United States federal income taxation.

If Dorian LPG Ltd. and its vessel-owning subsidiaries do not qualify for the exemption from tax under Section 883 of the Code, Dorian LPG Ltd. and its subsidiaries will be subject to a 4% tax on its “United States source shipping income,” imposed without the allowance for any deductions. For these purposes, “United States source shipping income” means 50% of the Shipping Income derived by Dorian LPG Ltd. and its vessel-owning subsidiaries that is attributable to transportation that begins or ends, but that does not both begin and end, in the United States.

For our fiscal years ended March 31, 2025, 2024 and 2023, we believe that we qualified, and we expect to qualify, for exemption under Section 883 and as a consequence, our gross United States source shipping income will not be subject to a 4% gross basis tax.

We are not aware of any claim that is reasonably possible and should be disclosed or probable and for which a provision should be established in the unaudited interim condensed consolidated financial statements. Also, if applicable, we record undiscounted receivables for probable loss recoveries from insurance or other parties. We are not aware of any material claim that is reasonably possible and should be disclosed in the unaudited interim condensed consolidated financial statements.

Financial Instruments and Fair Value Disclosures

21. Financial Instruments and Fair Value Disclosures

Our principal financial assets consist of cash and cash equivalents, investment securities, amounts due from related parties, derivative instruments, and trade accounts receivable. Our principal financial liabilities consist of long-term debt, accounts payable, amounts due to related parties, and accrued liabilities.

(a)Concentration of credit risk:  Financial instruments, which may subject us to significant concentrations of credit risk, consist principally of amounts due from our charterers, including the receivables from Helios Pool, and cash and cash equivalents. We limit our credit risk with amounts due from our charterers, including those through the Helios Pool, by performing ongoing credit evaluations of our charterers’ financial condition and generally do not require collateral from our charterers. We limit our credit risk with our cash and cash equivalents and restricted cash by placing it with highly-rated financial institutions.

(b)Interest rate risk:  One of our long-term bank loans is based on SOFR and hence we are exposed to movements thereto. We entered into interest rate swap agreements in order to hedge a majority of our variable interest rate exposure related to the 2023 A&R Debt Facility. Three of these swaps expired on March 26, 2025.

On January 20, 2023, we entered into an interest rate swap agreement with ING in order to manage our variable interest rate exposure risk by effectively converting a portion of our debt from a floating to a fixed rate. The notional value increased as the three other swaps amortized and now decreases with the debt outstanding under the 2023 A&R Debt Facility until final settlement in July 2029. The effect is to maintain a constant ratio between the debt outstanding under the 2023 A&R Debt Facility and the notional hedges. The initial notional value of $3.5 million became effective on June 26, 2023 with a fixed interest rate of 2.8525%. We have no exposure to floating rate movements on any of our other debt financings.

The principal terms of our interest rate swaps are as follows:

(c)Fair value measurements:  Interest rate swaps are stated at fair value, which is determined using a discounted cash flow approach based on marketbased SOFR swap yield rates. SOFR swap rates are observable at commonly quoted intervals for the full terms of the swaps and, therefore, are considered Level 2 items in accordance with the fair value hierarchy. The fair value of the interest rate swap agreements approximates the amount that we would have to pay or receive for the early termination of the agreements.

Additionally, we have, at times, taken positions in freight forward agreements (“FFAs”) as economic hedges to reduce the risk related to vessels trading in the spot market and to take advantage of fluctuations in market prices. Customary requirements for trading FFAs include the maintenance of initial and variation margins based on expected volatility, open position and mark-to-market of the contracts. FFAs are recorded as assets/liabilities until they are settled. Changes in fair value prior to settlement are recorded in unrealized gain/(loss) on derivatives. Upon settlement, if the contracted charter rate is less than the average of the rates for the specified route and time period, as reported by an identified index, the seller of the FFA is required to pay the buyer the settlement sum, being an amount equal to the difference between the contracted rate and the settlement rate, multiplied by the number of days in the specified period covered by the FFA. Conversely, if the contracted rate is greater than the settlement rate, the buyer is required to pay the seller the settlement sum. Settlement of FFAs are recorded in realized gain/(loss) on derivatives. FFAs are considered Level 2 items in accordance with the fair value hierarchy. We had no outstanding FFAs as of March 31, 2025.

The following table summarizes the location on the balance sheet of the financial assets and liabilities that are carried at fair value on a recurring basis, which comprise our financial derivatives all of which are considered Level 2 items in accordance with the fair value hierarchy:

As of March 31, 2025 and March 31, 2024, no fair value measurements for assets or liabilities under Level 1 or Level 3 were recognized in the consolidated balance sheets with the exception of cash and cash equivalents, restricted cash, and securities. We did not have any assets or liabilities measured at fair value on a non-recurring basis during the years ended March 31, 2025 and 2024.

(d)Book values and fair values of financial instruments.  In addition to the derivatives that we are required to record at fair value on our balance sheet (see (c) above) we have investment securities that are recorded at fair value and included in other current assets in our balance sheet. Additionally, on our March 31, 2024 balance sheet, we had available-for-sale debt securities consisting of U.S. treasury notes with an aggregate fair value of $11.5 million as of March 31, 2024 and face values of $1.8 million and $10.0 million that matured on September 30, 2024 and March 15, 2025, respectively, that were recorded at fair value as a current asset on our balance sheet. We had no such available-for-sale debt securities on our March 31, 2025 balance sheet. We have other financial instruments that are carried at historical cost including trade accounts receivable, equity securities, at cost, amounts due from related parties, cash and cash equivalents, restricted cash, accounts payable, amounts due to related parties and accrued liabilities for which the historical carrying value approximates the fair value due to the short-term nature of these financial instruments.

We have long-term bank debt, the 2023 A&R Debt Facility, for which we believe the carrying value approximates fair value as the facility bears interest at variable interest rates based on SOFR at March 31, 2024 and 2023, which is observable at commonly quoted intervals for the full terms of the loans, and hence are considered as a Level 2 item in accordance with the fair value hierarchy. We have long-term debt related to the Corsair Japanese Financing, Cresques Japanese Financing, Cratis Japanese Financing, Copernicus Japanese Financing, Chaparral Japanese Financing, Cougar Japanese Financing, Caravelle Japanese Financing, and Captain Markos Dual-Fuel Japanese Financing, (collectively, the “Japanese Financings”) that incur interest at a fixed rate. We have long-term debt related to the BALCAP Facility that incurs interest at a fixed rate. The Japanese Financings and BALCAP Facility are considered Level 2 items in accordance with the fair value hierarchy and the fair value of each is based on a discounted cash flow analysis using current observable interest rates.

U.S. Defined Contribution Plan

Qualifying full-time employees based in the United States participate in our 401(k) retirement plan and may contribute a portion of their annual compensation to the plan on a tax-advantaged basis, in accordance with applicable tax

law limits. On behalf of all participants in the plan, we provide a safe harbor contribution subject to certain limitations. Employee contributions and our safe harbor contributions are vested at all times. We recognized and paid compensation expense associated with the safe harbor contributions totaling $0.1 million for each of the years ended March 31, 2025, 2024, and 2023.

Greece Defined Benefit Plan

Our employees based in Greece participate in a required statutory defined benefit pension plan as required by the provisions of Greek law 2112/20 covering all eligible employees (the “Greek Plan”). We recognized a liability associated with our projected benefit obligation to the Greek Plan of $0.8 million and $0.9 million as of March 31, 2025 and 2024, respectively, representing a decrease of the liability of $0.1 million during the year ended March 31, 2025, an increase in the liability of $0.1 million during the year ended March 31, 2024, and a decrease in the liability of $0.2 million during the year ended March 31, 2023, for which we recognized income or expense on our consolidated statement of operations.

Denmark and U.K. Retirement Accounts

We contribute to retirement accounts for certain employees in Denmark and the United Kingdom based on a percentage of their annual salaries. For each of the years ended March 31, 2025, 2024 and 2023, we recognized compensation expense of $0.2 million related to these contributions.

23. Earnings Per Share (“EPS”)

Basic EPS represents net income attributable to common shareholders divided by the weighted average number of common shares outstanding during the measurement period. Our restricted stock shares include rights to receive dividends that are subject to the risk of forfeiture if service requirements are not satisfied, thus these shares are not considered participating securities and are excluded from the basic weighted-average shares outstanding calculation. Diluted EPS represents net income attributable to common shareholders divided by the weighted average number of common shares outstanding during the measurement period while also giving effect to all potentially dilutive common shares that were outstanding during the period.

The calculations of basic and diluted EPS for the periods presented were as follows:

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]

Our business operations, including our onshore operations and vessel operations, rely on information and operational technology systems, which could be targeted by various cyber threats including computer hackers and cyber terrorists. Reliance on information systems for vessel operations include the steering, navigation and propulsion systems of our vessels, communications and cargo management. Cybersecurity threats are of increased concern in today’s world as they can potentially, amongst other things, disrupt operations, compromise sensitive information, and expose us to litigation. Cybersecurity threats are continuously evolving and can vary widely. Some common types of cyber threats are not limited to, but include malware, phishing, social engineering, spoofing, supply-chain attacks, domain name system (DNS) tunneling, insider threats, code injection, identity-based attacks, and other cyber threats.

We have in place safety and security measures on our vessels and onshore operations to secure our vessels against cybersecurity incidents. Our processes for assessing, identifying and managing material risks from cybersecurity threats include, but are not limited to:

cybersecurity processes designed in accordance with international standards guidelines including the National Institute of Standards and Technology (NIST) Core Framework, ISO/IEC 27001, ISO/IEC 27002, the Tanker Management Self-Assessment (TMSA) 13 Elements, BIMCO, IMO Guidelines and International Ship and Port Facility Security (ISPS) Code, ISA/IEC 62443 for industrial Operational Technology, IACS UR E26/27, and OCIMF SIRE 2.0;

system protection mechanisms such as access procedures, antivirus programs, endpoint detection & response, maintaining a firewall and antispam, anti-phishing and email filtering processes;

implementation of internal policies and procedures, including an Information Security and Acceptable Use Policy, Information Security Management System Policy, Cyber Incident Response Procedures and Cyber Security Assessments on Policies and Procedures, to manage cybersecurity risk, implement incident reporting procedures and cybersecurity threat responses and regularly assess and monitor the Company’s cybersecurity measures;

periodic vulnerability assessment and penetration testing on shore and on vessels to review our cybersecurity
weaknesses, using either internal competencies or external firms;

a multi-vendor approach to reduce the risk of the compromise of a major cybersecurity vendor;

periodic cybersecurity awareness training for both ship and shore personnel; and

use of external cybersecurity vendors and threat detection and intelligence services to assist with incidence response and handling.

We also have processes to oversee and identify cybersecurity risks from cybersecurity threats associated with our use of suppliers, vendors, third-party service providers and IT support companies. These include the use of cybersecurity questionnaires, the performance of contract reviews to ensure IT-related compliance and the mitigation of identified information security risks and the sharing of our information security and acceptable use policy.

Cybersecurity Risk Management Processes Integrated [Flag] true
Cybersecurity Risk Management Processes Integrated [Text Block]

We have adopted the internal policies mentioned above to implement reporting procedures for any cybersecurity incident and a cybersecurity management framework to continuously monitor and access risk. These policies are developed and periodically reviewed by our IT department. The processes outlined above have also been integrated into our overall risk management strategy.

Cybersecurity Risk Materially Affected or Reasonably Likely to Materially Affect Registrant [Text Block]

We are not aware of any material risks from cybersecurity threats that have materially affected or are reasonably likely to materially affect the Company, including our business strategy, results of operations or financial condition. For a description of how risks from cybersecurity threats could materially affect us, including our business strategy, results of operations or financial condition, see “Item 1A. Risk Factors - Information technology failures and data security breaches, including as a result of cybersecurity attacks, could negatively impact our results of operations and financial condition, subject us to increased operating costs, and expose us to litigation”.

Cybersecurity Risk Board of Directors Oversight [Text Block]

Our cybersecurity risk management program is managed by our Chief Information Security and Sustainability Officer (the “CISSO”) and IT manager and is overseen by the Chief Executive Officer and the Chief Financial Officer. The CISSO, IT manager, and other members of the IT security team actively participate in cybersecurity groups and seminars, including those that are maritime-specific, for collaboration on cyber resilience, threat intelligence sharing, and best practices exchange. All members of the IT security team regularly undergo new training/certifications on cybersecurity and attend seminars/conferences related to cybersecurity to keep their knowledge and expertise current. At a minimum, the CISSO meets with the Chief Executive Officer and the Chief Financial Officer monthly to provide updates on cybersecurity programs, threats, and incidents, and advises the heads of all departments of any recent threats periodically.

The Nominating and Corporate Governance Committee (the “N&CG Committee”) of the Board of Directors is primarily responsible for the oversight of risks from cybersecurity threats. To fulfill this responsibility, the N&CG Committee receives regular updates, at least quarterly about the Company’s cybersecurity risks and mitigation program from management, specifically the CISSO or IT manager, including updates to the cybersecurity risk register, summaries of any material cybersecurity threats or incidents and responses thereto, updates on cybersecurity trends and the results of any assessments performed. The quarterly reports also include changes to cybersecurity processes, products and third-party service providers, third-party cybersecurity risk reviews, and regulatory changes.

Significant Accounting Policies (Policies)
12 Months Ended
Mar. 31, 2025
Significant Accounting Policies:  
Principles of consolidation

(a)   Principles of consolidation:  The consolidated financial statements incorporate the financial statements of the Company and its wholly-owned subsidiaries. Income and expenses of subsidiaries acquired or disposed of during the period are included in the consolidated statements of operations from the effective date of acquisition and up to the effective date of disposal, as appropriate. All intercompany balances and transactions have been eliminated.

Use of estimates

(b)   Use of estimates:  The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Other comprehensive income/(loss)

(c)   Other comprehensive income/(loss):  We follow the accounting guidance relating to comprehensive income, which requires separate presentation of certain transactions that are recorded directly as components of shareholders’ equity. We have no other comprehensive income/(loss) and, accordingly, comprehensive income/(loss) equals net income/(loss) for the periods presented and thus we have not presented this in the consolidated statements of operations or in a separate statement.

Foreign currency translation

(d)   Foreign currency translation:  Our functional currency is the U.S. Dollar. Foreign currency transactions are measured and recorded in the functional currency using the exchange rate in effect at the date of the transaction. As of balance sheet date, monetary assets and liabilities that are denominated in a currency other than the functional currency are adjusted to reflect the exchange rate at the balance sheet date and any gains or losses are included in the statements of operations. For the periods presented, we had no foreign currency derivative instruments.

Cash and cash equivalents

(e)   Cash and cash equivalents:  We consider highly liquid investments with an original maturity of three months or less such as time deposits, certificates of deposit, U.S. government securities, and money market funds to be cash equivalents.

Short-term investments

(f)   Short-term investments:  We consider short-term, highly-liquid time deposits placed with financial institutions, which are readily convertible into known amounts of cash with original maturities of more than three months, but less than 12 months at the time of purchase to be short-term investments.

Investment securities

(g)   Investment securities:  We hold investment securities that are classified as available-for-sale securities and are available to be sold in the future in response to our liquidity needs and asset-liability management strategies, among other considerations. Available-for-sale equity securities are reported at fair value, with unrealized gains and losses reported in in other gain/(loss), net on our consolidated statements of operations. Available-for-sale debt securities are reported at fair value, with unrealized gains and losses are reported in other comprehensive income/(loss). We had no unrealized gains and losses from debt securities reported in other comprehensive income/(loss) for the periods presented. We also hold equity securities that are recorded at cost that are evaluated for impairment periodically and, if needed, adjusted for other than temporary impairment. No impairment charges have been recorded for our equity securities, at cost.

Trade receivables, net and accrued revenues

(h)   Trade receivables, net and accrued revenues:  Trade receivables, net and accrued revenues, reflect receivables from vessel charters, net of an allowance for doubtful accounts. At each balance sheet date, all potentially uncollectible accounts are assessed individually for purposes of determining the appropriate provision for doubtful accounts. Provision for doubtful accounts for the periods presented was zero.

Due from related parties

(i)   Due from related parties:  Due from related parties reflect receivables from the Helios Pool and other related parties. Distributions of earnings due from the Helios Pool are classified as current and working capital contributed to the Helios Pool is classified as non-current.

Inventories

(j)   Inventories:  Inventories consist of bunkers on board the vessels when vessels are unemployed or are operating under voyage charters and lubricants and stores on board the vessels. Inventories are stated at lower of cost or net realizable value. Cost is determined by the first in, first out method. Net realizable value is the estimated selling price, less reasonably predictable costs of disposal and transportation.

Vessels, net and vessels under construction

(k)   Vessels, net and vessels under construction:  Vessels, net are stated at cost net of accumulated depreciation and impairment charges. The costs of the vessels acquired as part of a business acquisition are recorded at their fair value on the date of acquisition. The cost of vessels purchased consists of the contract price, less discounts, plus any direct expenses incurred upon acquisition, including improvements, commission paid, delivery expenses and other expenditures to prepare the vessel for her initial voyage. The initial purchase of LPG coolant for the refrigeration of cargo is also capitalized. Allocated interest costs incurred during construction are capitalized. Subsequent expenditures for conversions and major improvements, including scrubbers, are also capitalized when they appreciably extend the life, increase the earning capacity or improve the efficiency or safety of the vessels. Repairs and maintenance costs, including underwater inspection costs are expensed in the period incurred.

Costs capitalized to vessels during construction include shipyard costs, direct cost of project design and engineering, project site office administration costs, interest costs, and other such costs. Interest costs capitalized during the construction period of a vessel represent the amount which theoretically could have been avoided had we had not made installment payments on the vessel under construction.

Impairment of vessels

(l)   Impairment of vessels:  We review our vessels “held and used” for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. When the estimate of future undiscounted cash flows, excluding interest charges, expected to be generated by the use of the vessel is less than its carrying amount, the asset is evaluated for an impairment loss. Measurement of the impairment loss is based on the fair value of the vessel.

Vessel depreciation

(m)  Vessel depreciation:  Depreciation is computed using the straight-line method over the estimated useful life of the vessels, after considering the estimated salvage value. Each vessel’s salvage value is equal to the product of its lightweight tonnage and estimated scrap rate. Management estimates the useful life of its vessels to be 25 years from the date of initial delivery from the shipyard. Secondhand vessels are depreciated from the date of their acquisition through their remaining estimated useful life.

Drydocking and special survey costs

(n)   Drydocking and special survey costs:  Drydocking and special survey costs are accounted for under the deferral method whereby the actual costs incurred are deferred and are amortized on a straight-line basis over the period through the date the next survey is scheduled to become due. The classification societies provide guidelines applicable to LPG vessels relating to extended intervals for drydocking. Generally, we are required to drydock each of our vessels under 15 years of age every five years until they reach 15 years of age unless an extension of the drydocking to seven and one-half years is requested and granted by the classification society and the vessel is not older than 20 years of age. Costs deferred are limited to actual costs incurred at the yard and parts used in the drydocking or special survey. Costs deferred include expenditures incurred relating to shipyard costs, hull preparation and painting, inspection of hull structure and mechanical components, steelworks, machinery works, and electrical works. If a survey is performed prior to the scheduled date, the remaining unamortized balances are immediately written off. Unamortized balances of vessels that are sold are written-off and included in the calculation of the resulting gain or loss in the period of the vessel’s sale. The amortization charge is presented within Depreciation and amortization in the consolidated statements of operations.

Financing costs

(o)   Financing costs:  Financing costs incurred for obtaining new loans and credit facilities are deferred and amortized to interest expense over the respective term of the loan or credit facility using the effective interest rate method. Any unamortized balance of costs relating to loans/credit facilities repaid or refinanced is either expensed in the period the repayment or refinancing is made, or deferred and amortized over the terms of the respective credit facility, subject to the accounting guidance regarding Debt—Modifications and Extinguishments. Any unamortized balance of costs related to credit facilities repaid is expensed in the period. Any unamortized balance of costs relating to credit facilities refinanced is deferred and amortized over the term of the respective credit facility in the period the refinancing occurs, subject to the provisions of the accounting guidance relating to Debt—Modifications and Extinguishments. The unamortized financing costs are reflected as a reduction of Long-term debt—net of current portion and deferred financing fees in the consolidated balance sheet.

Restricted cash

(p)   Restricted cash:  Restricted cash represents minimum liquidity to be maintained with certain banks under our borrowing arrangements, pledged cash deposits, and amounts held in escrow. The restricted cash is classified as non-current in the event that its obligation is not expected to be terminated within the next twelve months as it is long-term in nature.

Leases

(q)   Leases: Refer to Note 11 for a description of our operating lease expenses for the years ended March 31, 2025, 2024, and 2023 and to Note 20 for a description of commitments related to our leases as of March 31, 2025. The following is a description of our leasing arrangements.

Time charter-out contracts

Our time charter revenues are generated from our vessels being hired by a third-party charterer for a specified period in exchange for consideration, which is based on a monthly hire rate. The charterer has full discretion over the ports subject to compliance with the applicable charter party agreement and relevant laws. In a time charter contract, we are responsible for all the costs incurred for running the vessel such as crew costs, vessel insurance, repairs and maintenance, and lubricants. The charterer bears the voyage related costs such as bunker expenses, port charges and canal tolls during the hire period. The performance obligations in a time charter contract are satisfied on a straight-line basis over the term of the contract beginning when the vessel is delivered to the charterer until it is redelivered back to us. The charterer generally pays the charter hire monthly in advance. We determined that our time charter contracts are considered operating leases and therefore fall under the scope of the guidance because (i) the vessel is an identifiable asset, (ii) we do not have substantive substitution rights, and (iii) the charterer has the right to control the use of the vessel during the term of the contract and derives the economic benefits from such use. Under the guidance, we elected the practical expedient available to lessors to not separate the lease and non-lease components included in the time charter revenue because (i) the pattern of revenue recognition for the lease and non-lease components is the same as it is earned by the passage of time and (ii) the lease component, if accounted for separately, would be classified as an operating lease.

We record time charter revenues on a straight-line basis over the term of the charter as service is provided. Time charter revenues received in advance of the provision of charter service are recorded as deferred income and recognized when the charter service is rendered. Deferred income or accrued revenue also may result from straight-line revenue recognition in respect of charter agreements that provide for varying charter rates. Deferred income and accrued revenue amounts that will be recognized within the next twelve months are presented as current, with amounts to be recognized thereafter presented as non-current. Revenues earned through the profit-sharing arrangements in the time charters represent contingent rental revenues that are recognized when earned and amounts are reasonably assured based on estimates provided by the charterer.

Net pool revenues—related party

As from April 1, 2015, we began operation of a pool. Net pool revenues—related party for each vessel in the pool is determined in accordance with the profit-sharing terms specified within the pool agreement. In particular, the pool manager calculates the net pool revenues using gross revenues less voyage expenses of all the pool vessels and less the general and administrative expenses of the pool and distributes the net pool revenues as time charter hire to participants based on:

pool points (vessel attributes such as cargo carrying capacity, fuel consumption, and speed are taken into consideration); and

number of days the vessel participated in the pool in the period.

We recognize net pool revenues—related party on a monthly basis, when the vessel has participated in the pool during the period and the amount of net pool revenues for the month can be estimated reliably. Revenue generated from the pool is accounted for as revenue from operating leases.

Time charter-in contracts

Our time charter-in contracts relate to the charter-in activity of vessels from third parties for a specified period of time in exchange for consideration, which is based on a monthly hire rate. We elected the practical expedient of the guidance that allows for contracts with an initial lease term of 12 months or less to be excluded from the operating lease right-of-use assets and lease liabilities recognized on our consolidated balance sheets.

Under the guidance, we elected the practical expedients available to lessees to not separate the lease and non-lease components included in the charter hire expense because (i) the pattern of revenue recognition for the lease and non-lease components is the same as it is earned by the passage of time and (ii) the lease component, if

accounted for separately, would be classified as an operating lease. We elected not to separate the lease and non-lease components included in charter hire expense, but to recognize operating lease expense as a combined single lease component for all time charter-in contracts.

Office leases

We carried forward our historical assessments of (i) whether contracts are or contain leases, (ii) lease classifications, and (iii) initial direct costs. For leases with terms greater than 12 months, we record the related right-of-use asset and lease liability as the present value of fixed lease payments over the lease term. For leases that do not provide a readily determinable discount rate, we use our incremental borrowing rate to discount lease payments to present value.

Under the guidance, we elected the practical expedients available to lessees to not separate the lease and non-lease components included in the office lease expense but to recognize operating lease expense as a combined single lease component for all office lease contracts because (i) the pattern of revenue recognition for the lease and non-lease components is the same as it is earned by the passage of time and (ii) the lease component, if accounted for separately, would be classified as an operating lease.

Voyage charter revenues

(r)

Voyage charter revenues:  In a voyage charter contract, a charterer hires a vessel to transport a specific agreed-upon cargo for a single voyage, which may contain multiple load ports and discharge ports. The consideration in such a contract is determined on the basis of a freight rate per metric ton of cargo carried or occasionally on a lump sum basis. The charter party generally has a minimum amount of cargo. The charterer is liable for any short loading of cargo or "dead" freight. The contract generally has standard payment terms of freight paid within three to five days after completion of loading. The contract generally has a "demurrage" or "despatch" clause. As per this clause, the charterer reimburses us for any potential delays exceeding the allowed laytime as per the charter party clause at the ports visited which is recorded as demurrage revenue. Conversely, the charterer is given credit if the loading/discharging activities happen within the allowed laytime, known as despatch, resulting in a reduction in revenue. The voyage contracts generally have variable consideration in the form of demurrage or despatch. Revenue from voyage charters is recognized when (i) the parties to the contract have approved the contract in the form of a written charter agreement and are committed to perform their respective obligations, (ii) we can identify each party’s rights regarding the services to be transferred, (iii) we can identify the payment terms for the services to be transferred, (iv) the charter agreement has commercial substance (that is, the risk, timing, or amount of our future cash flows is expected to change as a result of the contract) and (v) it is probable that we will collect substantially all of the consideration to which we will be entitled in exchange for the services that will be transferred to the charterer.

Voyage charter agreements do not contain a lease and are therefore considered service contracts that fall under the provisions of Accounting Standard Codification (“ASC”) 606 Revenue from Contracts with Customers. Voyage contracts are considered service contracts which fall under the provisions of ASC 606 because we retain control over the operations of the vessel, including directing the routes taken and vessel speed. We determined that a voyage charter agreement includes a single performance obligation, which is to provide the charterer with an integrated transportation service within a specified time period. In addition, we have concluded that a contract for a voyage charter meets the criteria to recognize revenue over time because the charterer simultaneously receives and consumes the benefits of our performance as the voyage progresses and therefore revenues are recognized on a pro rata basis over the duration of the voyage determined on a load-to-discharge port basis. In the event a vessel is acquired or sold while a voyage is in progress, the revenue recognized is based on an allocation formula agreed between the buyer and the seller. Demurrage is recognized when earned and collection is reasonably assured and despatch expense is recognized as incurred. Voyage charter revenue relating to voyages in progress as of the balance sheet date are accrued and presented in Trade receivables and accrued revenue in the consolidated balance sheet.

(s)   Voyage expenses:  Voyage expenses are expensed as incurred, except for expenses during the ballast portion of the voyage (period between the contract date and the date of the vessel’s arrival to the load port). Any expenses incurred during the ballast portion of the voyage such as bunker expenses, canal tolls and port expenses are

deferred and are recognized on a straight-line basis, in voyage expenses, over the voyage duration as we satisfy the performance obligations under the contract provided these costs are (1) incurred to fulfill a contract that we can specifically identify, (2) able to generate or enhance resources of the company that will be used to satisfy performance of the terms of the contract, and (3) expected to be recovered from the charterer. These costs are considered contract fulfillment costs because the costs are direct costs related to the performance of the contract and are expected to be recovered. Voyage expenses also consist of bunker expenses, canal tolls and port expenses incurred for vessels traveling to drydock and to be delivered to new owners in the case of a vessel sale are expensed as incurred.

Commissions

(t)   Commissions:  Charter hire commissions to brokers or managers, if any, are deferred and amortized over the related charter period and are included in Voyage expenses.

Charter hire expenses

(u)   Charter hire expenses:  Charter hire expenses in relation to vessels that we may occasionally charter in from third parties are recorded on a straight-line basis over the term of the charter as service is provided. Charter hire expenses paid in advance of the provision of charter service are recorded as a current asset and recognized when the charter service is rendered. Deferred expenses also may result from straight-line recognition in respect of charter agreements that provide for varying charter rates. Deferred expense amounts that will be recognized within the next twelve months are presented as current, with amounts to be recognized thereafter presented as noncurrent.

Vessel operating expenses (v)  Vessel operating expenses:  Vessel operating expenses are accounted for as incurred on the accrual basis. Vessel operating expenses include crew wages and related costs, the cost of vessel insurance, expenses relating to repairs and maintenance, the cost of spares and consumable stores and other miscellaneous expenses.
Stock-based compensation

(w)   Stock-based compensation: Stock-based compensation expense for grants to officers, directors and employees is measured at the grant date based on the estimated fair value of the awards and is recognized over the vesting period. We account for restricted stock award forfeitures upon occurrence.

Stock repurchases

(x)   Stock repurchases:  We record the repurchase of our shares of common stock at cost based on the settlement date of the transaction. These shares are classified as treasury stock unless canceled, which is a reduction in shareholders’ equity. Treasury shares are included in authorized and issued shares, but excluded from outstanding shares.

Dividends

(y)   Dividends:  Dividends are recognized in the consolidated statements of shareholders’ equity when they are declared by our board of directors (“Board of Directors”).

Segment reporting

(z)

Segment reporting:  Each of our vessels serves the same type of customer, has similar operations and maintenance requirements, operates in the same regulatory environment, and are subject to similar economic characteristics. Based on this, we have determined that our Company operates in one reportable segment, the international transportation of liquid petroleum gas with its fleet of vessels. Furthermore, when we charter a vessel to a charterer, the charterer is free to trade the vessel worldwide and, as a result, the disclosure of geographic information is impracticable. See Note 3 below for further disclosure related to segment reporting. Our Chief Executive Officer is the chief operating decision maker (“CODM”) and evaluates the operating results of the Company using the consolidated revenues and expenses as noted on the face of the consolidated statements of operations. The CODM assesses performance for the vessel operations segment and decides how to allocate resources based on consolidated net income and consolidated operating income.

Derivative instruments

(aa)  Derivative instruments:  All derivatives are stated at their fair value, as either a derivative asset or a liability. The fair value of the interest rate derivatives is based on a discounted cash flow analysis and their fair value changes are recognized in current period earnings. Settlements of derivative instruments are included in cash flows from operating activities in the consolidated statements of cash flows. When the derivatives do qualify for hedge accounting, depending upon the nature of the hedge, changes in fair value of the derivatives are either recognized in current period earnings or in other comprehensive income/(loss) (effective portion) until the hedged

item is recognized in the consolidated statements of operations. For the periods presented, no derivatives were accounted for as accounting hedges.

Fair value of financial instruments

(ab)  Fair value of financial instruments:  In accordance with the requirements of accounting guidance relating to Fair Value Measurements, the Company classifies and discloses its assets and liabilities carried at fair value in one of the following three categories:

Level 1:

Quoted market prices in active markets for identical assets or liabilities.

Level 2:

Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3:

Unobservable inputs that are not corroborated by market data.

Recent accounting pronouncements

(ac)  Recent accounting pronouncements:

In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-03, Disaggregation of Income Statement Expenses (“ASU 2024-03”), which requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements with the objective to address longstanding requests from investors to provide more detailed information about expenses presented on the face of the income statement. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within the fiscal years beginning after December 15, 2027 with early adoption permitted. The amendments are to be applied either prospectively to financial statements issued for the reporting periods after the effective date or retrospectively to any or all prior periods presented in the financial statements. We are currently evaluating the impact of the adoption of ASU 2024-03 on our consolidated financial statements and related disclosures.

We have considered all other recent accounting pronouncements issued and believe that none will have a material effect on our financial statements.
