Management’s Discussion and Analysis of Financial Condition and Results of Operations

Unless the context otherwise requires, all references in this report to “Navigator Holdings,” “our,” “we,” “us” and the “Company” refer to Navigator Holdings Ltd., a Marshall Islands corporation. All references in this report to our wholly-owned subsidiary “Navigator Gas L.L.C.” refer to Navigator Gas L.L.C., a Marshall Islands limited liability company. As used in this report, unless the context indicates or otherwise requires, references to “our fleet” or “our vessels” refers to the 53 vessels we owned and operated as of March 31, 2022.

This section should be read in conjunction with the interim financial statements and notes thereto presented elsewhere in this report, as well as the audited historical consolidated financial statements and notes thereto of Navigator Holdings Ltd. included in our Annual Report on Form 20-F, filed with the United States Securities and Exchange Commission, or the SEC, on April 28, 2022 (the “2021 Annual Report”). Among other things, those financial statements include more detailed information regarding the basis of presentation for the following information. The financial statements have been prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP, and are presented in U.S. Dollars unless otherwise indicated.

Overview

We are the owner and operator of 53 liquefied gas carriers, which includes the world’s largest fleet of handysize liquefied gas carriers. We also own a 50% share in an ethylene export marine terminal at Morgan’s Point, Texas on the Houston Ship Channel (the “Marine Export Terminal”) through a joint venture (the “Export Terminal Joint Venture”).

In August 2021, the Company acquired the fleet and businesses of two entities, Othello Shipping Company S.A. (Othello Shipping”) and Ultragas ApS (“Ultragas”) from Naviera Ultranav Limitada (“Ultranav” and such acquisition, the “Ultragas Transaction”). The Company owns 100% of Othello Shipping and Ultragas which together own and operate 16 liquefied petroleum gas (“LPG”) carriers ranging in size from 3,770 to 22,000 cbm as of March 31, 2022, all of which are semi-refrigerated vessels and eight of them are capable of carrying ethylene.

Our liquefied gas carrier fleet currently consists of 39 semi- or fully-refrigerated handysize liquefied gas carriers, nine of which are ethylene/ethane capable. We define handysize liquefied gas carriers as those liquefied gas carriers with capabilities between 15,000 and 24,999 cubic meters, or “cbm”. In addition, we have five larger 37,300 – 38,000 cbm midsize liquefied gas carriers, four of which are ethylene/ethane-capable semi-refrigerated liquefied gas carriers; five 12,000 cbm ethylene carriers and four smaller 3,770 –9,000 cbm semi-refrigerated liquefied gas carriers, of which three are also ethylene capable.

Our handysize liquefied gas carriers typically transport LPG on short or medium routes that may be uneconomical for smaller vessels and can call at ports that are unable to support larger vessels due to limited onshore capacity, absence of fully-refrigerated loading infrastructure and/or vessel size restrictions. These handysize liquefied gas carriers are amongst the largest semi-refrigerated vessels in the world, which also makes them capable of transporting petrochemicals on long routes, typically intercontinental.

We play a vital role in the liquefied gas supply chain for energy companies, industrial consumers and commodity traders, with our sophisticated vessels providing an efficient and reliable ‘floating pipeline’ between the parties. We carry LPG for major international energy companies, state-owned utilities and reputable commodities traders. LPG, which consists of propane and butane, is a relatively clean alternative energy source with more than 1,000 applications, including as a heating, cooking and transportation fuel and as a petrochemical and refinery feedstock. LPG is a by-product of oil refining and natural gas extraction, and shale gas, principally from the United States.

We also carry petrochemical gases for numerous industrial users. Petrochemical gases, including ethylene, propylene, butadiene and vinyl chloride monomer, are derived from the cracking of petroleum feedstocks such as ethane, LPG and naphtha and are primarily used as raw materials in various industrial processes, like the manufacture of plastics, vinyl and rubber, with a wide application of end uses. Our vessels also carry ammonia for the producers of fertilizers, a main use of ammonia for the agricultural industry, and for ammonia traders.

Our Marine Export Terminal has a 30,000 ton capacity cryogenic storage tank. The Marine Export Terminal has the capacity to export at least one million tons of ethylene per year and provides the capability to load ethylene from the storage tank at rates of 1,000 tons per hour. The Marine Export Terminal has entered into offtake agreements, which have minimum terms of five years for a committed 938,000 tons of ethylene through the terminal annually.

Recent Developments

Effect of Russian Invasion of Ukraine

We currently have four charterparties with a Russian counterparty that were entered into in 2012 and 2017, two of which expire in June/July 2022 and two that expire in December 2023. These charterparties cannot be terminated without the consent of both parties, unless the counterparty was to become a sanctioned entity or our dealings with that counterparty were to be otherwise prohibited by sanctions, which would render the charters void. The charter parties that expire in June 2022, will not be extended and both vessels have instead been chartered for a twelve month period with a leading Nordic producer of petrochemicals.

At the beginning of the Russian invasion of Ukraine, we had employed an aggregate of approximately 120 Russian and Ukrainian officers on board our vessels, many of whom were on the same vessels. We have thus far only experienced solidarity onboard and have had no issues in operating these vessels. The total number of combined Russian and Ukrainian officers has reduced to below 100 on our vessels. We continue to monitor this situation closely, and there may be restrictions, logistical challenges or an inability to employ both nationalities in the near future.

Marine Export Terminal

Ethylene throughput for the first quarter of 2022 at the Marine Export Terminal totaled 267,110 metric tons. Throughput to international markets in each of January and March 2022 exceeded 100,000 metric tons, affirming the capability of the terminal to export above the nameplate capacity of one million metric tons per year. February 2022 experienced less volume due to reduced ethylene demand leading up to the Lunar New Year and the Winter Olympics being held in China. April and May 2022 volumes remain strong at around 100,000 metric tons, reflecting demand from producers and end users for competitively priced U.S. ethylene monomers.

Shipping Trends

The handysize semi-refrigerated and fully-refrigerated 12 month time charter rate assessment increased by $5,000 per calendar month (“pcm”) and $15,000 pcm, respectively, during the first quarter of 2022, to $685,000 pcm and $635,000 pcm, respectively, with the most recent weekly shipbroker reports showing a further increase to $705,000 pcm and $650,000 pcm, respectively. The handysize ethylene 12 month time charter assessment has increased from $875,000 pcm at the beginning of 2022 to a current level of $900,000 pcm.

The rise in shipping rates can generally be ascribed to three principal underlying factors. First, the Ukrainian conflict is disrupting traditional supply sources, challenging the historical sourcing of product from the closest geographical location. European customers are increasingly looking further afield when sourcing products, which results in longer seaborne voyages for the gas shipping industry. This is true for all the products we transport, across LPGs, petrochemicals and ammonia. Secondly, U.S. natural gas liquid (“NGL”) production and exports are on the rise. According to EIA, U.S. propane production for April 2022 is 7% above the level for April 2021 and is likely to be the highest level on record since the commencement of shale gas production. Seaborne export volumes of propane during April 2022 were up 14% compared to April 2021. Increased production and exports are also seen across other NGLs and derivative products. U.S. ethylene exports reached a record high of 137,000 metric tons during April 2022 bringing incremental demand for seaborne transport. Thirdly, there is less substitution effect across the gas carrier segments. Increased U.S. exports of LPG are providing incremental shipping demand, which is positive for larger gas carriers, which in turn reduces competition from other size categories within the LPG shipping segment. This dynamic also applies to the handysize segment. When ethylene capable vessels are employed in ethylene or ethane trades, and when fully-refrigerated vessels are employed in ammonia trades, there are less vessels competing for LPG and the more straightforward petrochemicals, which in turn is positive for the semi-refrigerated sub-segment of the handysize vessels. One recent example was a charter extension for four of our semi-refrigerated vessels currently employed carrying LPG from the west coast of North America, which achieved a charter rate increase of approximately 20% over the charter rate agreed a year ago.

Unaudited Results of Operations for the Three Months Ended March 31, 2022 Compared to the Three Months Ended March 31, 2021

The following table compares our operating results for the three months ended March 31, 2021 and 2022:

Operating Revenues. Operating revenues, net of address commissions, was $100.4 million for the three months ended March 31, 2022, an increase of $19.9 million or 24.7% compared to $80.5 million for the three months ended March 31, 2021. This increase was primarily due to:

7

The following table presents selected operating data for the three months ended March 31, 2021 and 2022, which we believe are useful in understanding the basis for movement in our operating revenues. It does not include our nine owned smaller vessels in the independent commercially managed Unigas Pool or the five vessels owned by Pacific Gas in our Luna Pool.

8

Operating Revenues – Unigas Pool. Operating revenues – Unigas Pool was $13.5 million for the three months ended March 31, 2022 and represents our share of the revenues earned from our nine vessels (following the sale of the Happy Bird on March 7, 2022) operating within the Unigas Pool, based on agreed pool points. These vessels were acquired as part of the Ultragas Transaction in August 2021, and therefore there are no Operating Revenues—Unigas Pool for the three months ended March 31, 2021.

Operating Revenues – Luna Pool Collaborative Arrangements. Pool earnings are aggregated and then allocated (after deducting pool overheads and managers fees) to the Pool Participants in accordance with the Pooling Agreement. Operating revenues—Luna Pool collaborative arrangements was $5.9 million for the three months ended March 31, 2022, compared to $5.2 million for the three months ended March 31, 2021 and represents our share of pool net revenues generated by the other participant’s vessels in the pool. The Luna Pool, which comprises nine of the Company’s ethylene vessels and five ethylene vessels from Pacific Gas Pte. Ltd., focuses on the transportation of ethylene and ethane to meet the growing demands of our customers.

Brokerage Commissions. Brokerage commissions, which typically vary between 1.25% and 2.5% of operating revenues, increased by $0.2 million or 17.9% to $1.4 million for the three months ended March 31, 2022, from $1.2 million for the three months ended March 31, 2021, primarily due to an increase in operating revenues on which brokerage commissions are based.

Voyage Expenses. Voyage expenses increased by $5.2 million or 33.2% to $20.8 million for the three months ended March 31, 2022, from $15.6 million for the three months ended March 31, 2021. This increase is primarily due to voyage expenses of the additional seven handysize vessels acquired as part of the Ultragas Transaction. These voyage expenses are pass through costs, corresponding to an increase in operating revenues of the same amount.

Voyage Expenses – Luna Pool Collaborative Arrangements. Voyage expenses – Luna Pool collaborative arrangements were $4.6 million for the three months ended March 31, 2022, compared to $4.1 million for the three months ended March 31, 2021. These voyages expenses – Luna Pool collaborative arrangements represent the other participant’s share of pool net revenues generated by our vessels in the pool. The net effect after deducting operating revenues – Luna Pool collaborative arrangements was that the other participant’s vessels contributed $1.3 million to our vessels in the Luna Pool for the three months ended March 31, 2022, compared to the other participant’s vessels contributing $1.1 million to our vessels for the three months ended March 31, 2021.

Vessel Operating Expenses. Vessel operating expenses increased by $11.1 million or 41.0% to $38.1 million for the three months ended March 31, 2022, from $27.0 million for the three months ended March 31, 2021, primarily as a result of the additional Ultragas vessels joining the fleet. Average daily vessel operating expenses decreased by $51 per vessel per day, or 0.6%, to $7,841 per vessel per day for the three months ended March 31, 2022, compared to $7,892 per vessel per day for the three months ended March 31, 2021.

Depreciation and Amortization. Depreciation and amortization increased by $12.1 million or 62.6% to $31.3 million for the three months ended March 31, 2022, from $19.3 million for the three months ended March 31, 2021. Of this increase, $5.9 million results from the additional 16 vessels in the fleet, acquired as part of the Ultragas Transaction and $6.1 million results from the change in the useful economic lives of the vessels in the fleet from 30 years to 25 years on January 1, 2022. Depreciation and amortization included amortization of capitalized drydocking costs of $3.7 million and $2.2 million for the three months ended March 31, 2022 and 2021 respectively.

Profit from Sale of Vessel. Profit from sale of vessel for the three months ended March 31, 2022 was $0.4 million and related to the sale of the vessel, Happy Bird. The sale of Navigator Neptune was at book value, therefore there was no profit or loss on the sale of this vessel.

General and Administrative Costs. General and administrative costs slightly increased by $0.1 million or 1.0% to $6.3 million for the three months ended March 31, 2022, from $6.3 million for the three months ended March 31, 2021, primarily as a result of the additional general and administrative costs of Ultragas of $1.2 million, off-set by a reallocation of technical management costs to vessel operating expenses of $0.7 million and a reduction of other costs of $0.3 million including cost reductions associated with the closure of our New York office.

Other Income. Other income was $0.1 million for both the three months ended March 31, 2022 and 2021 and consists of that portion of the management fees for commercial and administrative activities performed by the Company for the Luna Pool, relating to the other participant’s vessels.

Non-operating Results     

Foreign Currency Exchange Gain/(Loss) on Senior Secured Bonds. Exchange gains and losses relate to non-cash movements on our 600 million Norwegian Kroner 2018 Bonds which are translated to U.S. Dollar at the prevailing exchange rate as of March 31, 2022. The foreign currency exchange loss of $0.8 million for the three months ended March 31, 2022, was a result of the Norwegian Kroner strengthening against the U.S. Dollar, being NOK 8.7 to USD 1.0 as of March 31, 2022, compared to NOK 8.8 to USD 1.0 as of December 31, 2021.

9

Unrealized Gains on Non-designated Derivative Instruments. The unrealized gains on non-designated derivative instruments of $15.2 million for the three months ended March 31, 2022, primarily relates to the fair value gains of our interest rate swaps across a number of our secured term loan and revolving credit facilities of $13.0 million, as a result of significant increases in forward U.S. Libor rates relative to the fixed rates applicable on these secured term loan and revolving credit facilities; and a gain in our cross-currency interest rate swap of $2.2 million, which is due to the strengthening of the Norwegian Kroner against the U.S. Dollar. The unrealized gain on our interest rate swaps for the three months ended March 31, 2021, was $0.3 million in addition to an unrealized gain on the cross-currency interest rate swap of $0.2 million.

Interest Expense. Interest expense increased by $2.0 million, or 22.3%, to $11.0 million for the three months ended March 31, 2022, from $9.0 million for the three months ended March 31, 2021. This is primarily as a result of interest on the additional debt assumed as part of the Ultragas Transaction in August 2021.

Income Taxes. Income taxes related to taxes on our subsidiaries incorporated in the United States of America, United Kingdom, Poland and Singapore and our consolidated variable interest entity (“VIE”), incorporated in Malta. For the three months ended March 31, 2022, we had a tax charge of $0.4 million compared to taxes of $0.1 million for the three months ended March 31, 2021, with the increase primarily being as a result of taxes on our portion of the profits from the Marine Export Terminal.

Share of Result of Equity Method Investments. The share of result of the Company’s 50% ownership in the Export Terminal Joint Venture was income of $6.5 million for the three months ended March 31, 2022, compared to a loss of $0.6 million for the three months ended March 31, 2021. This increase is primarily as a result of increased volumes exported through the Marine Export Terminal, which were 267,110 tons for the three months ended March 31, 2022, compared to 90,376 tons for the three months ended March 31, 2021, following mechanical integrity concerns on the pipeline carrying the ethylene from the caverns at Mont Belvieu to the Marine Export Terminal in February and March 2021.

Non-Controlling Interest. We entered into a sale and leaseback arrangement in November 2019 with a wholly-owned special purpose vehicle (“lessor SPV”) of a financial institution. Although we do not hold any equity investments in this lessor SPV, we have determined that we are the primary beneficiary of this entity and accordingly, we are required to consolidate this VIE into our financial results. Thus, the income attributable to the financial institution of $0.4 million is presented as the non-controlling interest in our financial results for both the three months ended March 31, 2022 and 2021.

Liquidity and Capital Resources

Liquidity and Cash Needs

Our primary sources of funds are cash and cash equivalents, cash from operations, undrawn bank borrowings and proceeds from bond issuances. As of March 31, 2022, we had cash and cash equivalents of $168.1 million along with $22.8 million available to be drawn down on two of our secured revolving credit facilities.

Our secured term loan facilities and revolving credit facilities require that the borrowers have liquidity (including undrawn available lines of credit with a maturity exceeding 12 months) of no less than (i) $25.0 million, $35.0 million, or $50.0 million, as applicable to the relevant loan facility, or (ii) 5% of Net Debt or total debt which was $47.6 million as of March 31, 2022, whichever is greater. Please see “—Secured Term Loan Facilities and Revolving Credit Facilities”, “—2018 Senior Secured Bonds” and “2020 Senior Unsecured Bonds” below.

Our primary uses of funds are drydocking expenditures, voyage expenses, vessel operating expenses, general and administrative costs, expenditures incurred in connection with ensuring that our vessels comply with international and regulatory standards, financing expenses and repayment of bonds and bank loans. In addition to operating expenses, our medium-term and long-term liquidity needs relate to debt repayments, potential future newbuildings or acquisitions and any further development of the Marine Export Terminal in our Export Terminal Joint Venture or other projects.

As of March 31, 2022, we had $968.3 million in outstanding obligations, which includes principal repayments on long-term debt, including our bonds, commitments in respect of the Navigator Aurora Facility and office lease commitments. On August 4, 2021, we assumed additional debt associated with the Ultragas Transaction. This debt as of March 31, 2022, stood at $180.3 million, consisting of five bank loans, secured on a total of 13 of the 18 vessels acquired, with three vessels being unencumbered and two vessels subsequently sold following the Ultragas Transaction. The bank loans which have half-yearly aggregate repayments of approximately $13.5 million, mature starting in 2025 and accrue interest at U.S. Libor plus a margin of between 1.9% and 2.65%. In each case, U.S. Libor is fixed by an interest rate swap of approximately 2.0%. The financial covenants on these five bank loans were modified to be consistent with those of the Company’s other credit facilities. Of the total outstanding obligations, $129.0 million matures during the remainder of 2022, and $839.3 million matures after such date.

We believe, given our current cash balances, that our financial resources, including the cash expected to be generated within the year, will be sufficient to meet our liquidity and working capital needs for at least the next twelve months, taking into account our existing capital commitments and debt service requirements.

Capital Expenditures

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

We currently have no newbuildings on order. However, we may place newbuilding orders or acquire additional vessels as part of our growth strategy, or may invest further in terminal infrastructures, such as expanding our existing Marine Export Terminal or other import or export terminals.

11

Operating Cash Flows. Net cash provided by operating activities for the three months ended March 31, 2022 increased to $34.0 million, from $29.2 million for the three months ended March 31, 2021, an increase of $4.8 million. This increase was primarily due to an improvement in net income of $24.2 million, which included additional depreciation of $12.1 million, off-set by increased gains on derivative instruments; an increase in our share of the result from equity method investments of $7.1 million; an increase in drydocking payments of $1.8 million and changes in working capital of $8.9 million during the three months ended March 31, 2022, compared to the three months ended March 31, 2021.

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

We are required to drydock each vessel once every five years until it reaches 15 years of age, after which we drydock vessels every two and a half to three years. Drydocking each vessel takes approximately 30 days in total. Drydocking days generally include approximately 5-10 days of voyage time to and from the drydocking shipyard and approximately 15-20 days of actual drydocking time. Four of our vessels completed their respective drydockings during the three months ended March 31, 2022, with a further nine vessels scheduled for drydocking during the remainder of 2022.

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

Investing Cash Flows. Net cash provided by investing activities of $34.4 million for the three months ended March 31, 2022 primarily consisted of $26.5 million relating to proceeds received from the sale of two of our vessels, distributions received from our investment in the Export Terminal Joint Venture of $7.6 million and insurance recoveries on existing damage claims of $0.9 million; offset by investment of $0.5 million in ballast water treatment systems which are being retrofitted on our vessels during dry dock to comply with the requirements of the Ballast Water Management Convention.

Net cash used in investing activities of $3.0 million for the three months ended March 31, 2021 primarily consisted of our investment of $4.0 million in capital contributions made to our Export Terminal Joint Venture and investment of $0.2 million in ballast water treatment systems, offset by $0.8 million of distributions received from equity method investments and insurance recoveries on existing damage claims of $0.4 million.

Financing Cash Flows. Net cash used in financing activities of $24.5 million for the three months ended March 31, 2022, related to regular quarterly repayments on our secured term loan facilities of $22.9 million and an extemporaneous repayment of $1.6 million on the Navigator Aurora Facility held within our consolidated lessor VIE.

Net cash used in financing activities of $0.2 million for the three months ended March 31, 2021, related to regular quarterly repayments on our secured term loan facilities of $16.4 million and an extemporaneous repayment of $1.8 million on the Navigator Aurora Facility held within our consolidated lessor VIE, offset by a final draw down of $18.0 million from the Terminal Facility.

12

Terminal Facility

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

Term and Facility Limits. The Terminal Facility is now converted into a term loan with a final maturity of December 31, 2025. Based on the committed throughput agreements for the Marine Export Terminal, a total of $69.0 million was drawn under the Terminal Facility of which $51.0 million was outstanding as of March 31, 2022.

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

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

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

On May 6, 2021, the Company obtained a waiver from the lenders under the Terminal Facility, which is retrospective with effect from the date of its inception, to correct a technical inconsistency in the Terminal Facility, involving a restrictive covenant relating to taking affirmative action regarding the treatment of tax status of the borrower as a corporation for U.S. federal, state or local income tax purposes. The waiver required among other things, an amendment to the credit agreement and other loan documentation to remediate the inconsistency and to set aside and fund a tax reserve, based on the subsequent three months’ tax liabilities. The terms of the waiver were complied with and the amendment entered into on August 4, 2021.

Secured Term Loan Facilities and Revolving Credit Facilities

General. Navigator Gas L.L.C., our wholly-owned subsidiary, and certain of our vessel-owning subsidiaries have entered into various secured term loan facilities and revolving credit facilities as summarized in the table below. For additional information regarding our secured term loan facilities and revolving credit facilities, please read “Item 5—Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Secured Term Loan Facilities and Revolving Credit Facilities” in the 2021 Annual Report.

The table below summarizes our secured term loan and revolving credit facilities as of March 31, 2022:

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

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

The borrowers are also required to deliver semi-annual compliance certificates, which include valuations of the vessels securing the applicable

facility from an independent ship broker. Upon delivery of the valuation, if the market value of the collateral vessels is less than 125% to 135% of the outstanding indebtedness under the applicable facilities, the borrowers must either provide additional collateral or repay any amount in excess of 125% to 135% of the market value of the collateral vessels, as applicable. This covenant is measured semi-annually on June 30 and December 31.

Other than as stated, our compliance with the financial covenants listed above is measured as of the end of each fiscal quarter. As of March 31, 2022, we were in compliance with all covenants under the secured term loan facilities and revolving credit facilities.

Lessor VIE Debt

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

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

Navigator Aurora Facility

In October 2019, the SPV, which owns Navigator Aurora, entered into secured financing agreements for $69.1 million consisting of a USD denominated loan facility, the “Navigator Aurora Facility”. The Navigator Aurora Facility is a seven year unsecured loan provided by OCY Malta Limited, the parent of OCY Aurora Ltd., The Navigator Aurora Facility is subordinated to a further bank loan where OCY Aurora Ltd is the guarantor and Navigator Aurora is pledged as security. Please read Note 6—Secured Term Loan Facilities and Revolving Credit Facilities to the unaudited condensed consolidated financial statements for additional information. The Navigator Aurora Facility bears interest at 3-month U.S. LIBOR plus a margin of 185 basis points and is repayable by the SPV with a balloon payment on maturity. As of March 31, 2022, there was $53.2 million in borrowings outstanding under the Navigator Aurora Facility (December 31, 2021, $54.8 million.).

Critical Accounting Estimates

We prepare our consolidated financial statements in accordance with U.S. GAAP, which requires us to make estimates in the application of our accounting policies based on our best assumptions, judgments and opinions. On a regular basis, management reviews the accounting policies, assumptions, estimates and judgments to ensure that our consolidated financial statements are presented fairly and in accordance with U.S. GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates, and such differences could be material. For a description of our material accounting policies, please read Note 2—Summary of Significant Accounting Policies to the 2021 Annual Report.

Quantitative and Qualitative Disclosures About Market Risk

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

Interest Rate Risk

Historically, we have been subject to limited market risks relating to changes in interest rates because we did not have significant amounts of floating rate debt outstanding. Navigator Gas L.L.C., our wholly-owned subsidiary, and certain of our vessel-owning subsidiaries are parties to secured term loan and revolving credit facilities that bear interest at an interest rate of U.S. LIBOR plus 185 to 270 basis points. At March 31, 2022, our outstanding debt that is subject to variable interest rates, net of the amount subject to interest rate swap agreements, was $451.3 million. Based on this, a variation in U.S. LIBOR of 100 basis points would result in an increase of $4.5 million in annual interest paid on our indebtedness outstanding as of March 31, 2022.

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

Foreign Currency Exchange Rate Risk

Our primary economic environment is the international shipping market. This market utilizes the U.S. Dollar as its functional currency. Consequently, virtually all of our revenues are in U.S. Dollars. Our expenses, however, are in the currency invoiced by each supplier, and we remit funds in the various currencies invoiced. We incur some vessel operating expenses and general and administrative costs in foreign currencies, primarily the Euro, Pound Sterling Danish Kroner and Polish Zloty and therefore there is a transactional risk that currency fluctuations could have a negative effect on our cashflows and financial condition. We believe these adverse effects would not be material and we have not entered into any derivative contracts to mitigate our exposure to foreign currency exchange rate risk during 2022.

In November 2018, we issued senior secured bonds in an aggregate amount of NOK 600 million. Please read “2018 Senior Secured Bonds”. We have entered into a cross currency interest rate swap to mitigate the risk of currency movements for both interest payments during the five-year tenor of the 2018 Bonds and for the principal repayments at maturity in November 2023. However, if the Norwegian Kroner weakens relative to the U.S. Dollar beyond a certain threshold, we are required to place cash collateral with our swap providers for the forecast future liability on the cross-currency interest rate swap. In the event the depreciation of the Norwegian Kroner relative to the U.S. Dollar is significant, the cash collateral requirements could adversely affect our liquidity and financial position.

In addition, at each quarterly interest payment date, the cross-currency interest rate swap exchanges a receipt of floating interest of 6.0% plus 3-month NIBOR on NOK 600 million for a U.S. dollar payment of floating interest of 6.608% plus 3-month U.S. LIBOR on the approximate $71.7 million principal amount. The purpose of the cross-currency interest rate swap is to economically hedge the foreign currency exposure on the payments of interest and principal of the Company’s NOK-denominated 2018 Bonds due in 2023. The cross-currency interest rate swap is remeasured to fair value at each reporting date.

Inflation

Certain of our operating expenses, including crewing, insurance and drydocking costs, are subject to fluctuations as a result of market forces. Increases in bunker costs could have a material effect on our future operations if the number and duration of our voyage charters or COAs increases. In the case of the 44 vessels owned and commercially managed by us as of March 31, 2022, 27 were employed on time charter and as such it is the charterers who pay for the fuel on those vessels. If our vessels are employed under voyage charters or COAs, freight rates are generally sensitive to the price of fuel. However, a further sharp rise in bunker prices may have a temporary negative effect on our results since freight rates generally adjust only after prices settle at a higher level.

Credit Risk

We may be exposed to credit risks in relation to vessel employment and at times may have multiple vessels employed by one charterer. We consider and evaluate concentration of credit risk continuously and perform ongoing evaluations of these charterers for credit risk. At March 31, 2022, no more than four of our vessels were employed by the same charterer. We invest our surplus funds with reputable financial institutions, with original maturities of no more than three months, in order to provide the Company with flexibility to meet all requirements for working capital and for capital investments.
