CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Our disclosure and analysis in this report pertaining to our operations, cash flows and financial position, including, in particular, the likelihood of our success in developing and expanding our business, include forward-looking statements. The Private Securities Litigation Reform Act of 1995, or the PSLRA, provides safe harbor protections for forward-looking statements in order to encourage companies to provide prospective information about their business. Forward-looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions and other statements, which are other than statements of historical facts.

We are taking advantage of the safe harbor provisions of the PSLRA and are including this cautionary statement in connection therewith. This document and any other written or oral statements made by us or on our behalf may include forward-looking statements, which reflect our current views with respect to future events and financial performance. This report includes assumptions, expectations, projections, intentions and beliefs about future events. These statements are intended as "forward-looking statements." We caution that assumptions, expectations, projections, intentions and beliefs about future events may and often do vary from actual results and the differences can be material. Statements that are predictive in nature, that depend upon or refer to future events or conditions, or that include words such as "expects," "anticipates," "intends," "plans," "believes," "estimates," "seeks," "targets," "potential," "continue," "contemplate," "possible," "likely," "might," "will," "would," "could," "projects," "forecasts," "may," "should" and similar expressions are forward-looking statements.

All statements in this report that are not statements of either historical or current facts are forward-looking statements. Forward-looking statements include, but are not limited to, such matters as:

• general Liquefied Natural Gas ("LNG") shipping market conditions, including fluctuations in charter rates and vessel values; • the volatility of prevailing spot market charter rates; • our future operating or financial results; • global and regional economic and political conditions and developments, armed conflicts, including the war between Russia and Ukraine and possible cessation of such war in Ukraine, the conflict between Israel and Hamas and related conflicts in the Middle East, the Houthi attacks in the Red Sea and Gulf of Aden, threats by Iran to close the Strait of Hormuz, trade wars, tariffs, embargoes and strikes; • stability of Europe and the Euro; • inflationary pressures and central bank policies included to combat overall inflation and rising interest rates andforeign exchange rates; • our business strategy and expected and unexpected capital spending and operating expenses, including dry-docking, surveys, upgrades, insurance costs, crewing and bunker costs; • our expectations of the availability of vessels to purchase, the time it may take to construct new vessels and risks associated with vessel construction and vessels' useful lives; • LNG market trends, including charter rates and factors affecting supply and demand; • the supply of and demand for vessels comparable to ours, including against the background of possibly accelerated climate change transition worldwide which would have an accelerated negative effect on the demand for fossil fuels, including LNG, and thus transportation of LNG; • our financial condition and liquidity, including our ability to repay or refinance our indebtedness and obtain financing in the future to fund capital expenditures, acquisitions and other general corporate activities;

FLEX LNG Ltd.

• our ability to enter into and successfully deliver our vessels under time charters or other employment arrangements after our current charters expire and our ability to earn income in the spot market (which includes vessel employment under single voyage spot charters and time charters with an initial term of less than six months); • our ability to compete successfully for future chartering opportunities and newbuilding opportunities (if any); • estimated future maintenance and replacement capital expenditures; • the expected cost of, and our ability to comply with, governmental regulations, including environmental regulations, maritime self-regulatory organization standards, as well as standard regulations imposed by our charterers applicable to our business; • customers’ increasing emphasis on environmental and safety concerns; • availability of and ability to maintain skilled labor, vessel crews and management; • our anticipated incremental general and administrative expenses as a publicly traded company; • business disruptions, including supply chain disruption and congestion, including port congestion, due to natural orother disasters or otherwise; • potential physical disruption of shipping routes due to accidents, climate-related incidents, and public health threats; and • our ability to maintain relationships with major LNG producers and traders.

Many of these statements are based on our assumptions about factors that are beyond our ability to control or predict and are subject to risks and uncertainties that are described more fully in "Item 3. Key Information—D. Risk Factors" of our Annual Report (as defined below).

FLEX LNG Ltd.

Employment of Our Fleet and Our Customers

In March 2025, Flex Constellation was re-delivered from the existing time charter contract and was employed in the spot market, until the commencement of a 15-year time charter contract during the first or second quarter of 2026.

In April 2025, the charterer of Flex Artemis elected not to exercise the option under the time charter. Flex Artemis is expected to be re-delivered from the original 5-year variable hire contract in the third quarter of 2025. Following the re-delivery, Flex Artemis will perform her scheduled dry-docking and will subsequently be marketed for short and long-term contracts.

In June and July 2025, we successfully completed our scheduled drydocking for Flex Aurora and Flex Resolute, respectively.

At the date of this report, the firm contract coverage is 85.7% for the remainder of 2025, and the aggregate firm contract backlog for the fleet is 56 years based on the earliest charter expirations, which could increase to 85 years if our charterers exercise all of the contracted options.

We achieved technical uptime excluding offhire for drydocking on our vessels of 100.0% in the second quarter 2025.

For the remainder of 2025, we have 14.5% exposure to the spot market. The 2025 market exposure is related to our market-linked contract for Flex Artemis; and the open period in respect of Flex Constellation and Flex Artemis upon re-delivery from the current charters.

Business Developments

In May 2025, at the 2025 Annual General Meeting of Shareholders ("AGM"), the Company's shareholders approved the reduction of the Company's Share Premium Account (Recognized as Additional paid-in capital in the Consolidated Statements of Changes in Shareholders’ Equity) of the Company by $200.0 million; and credit the same amount resulting from the reduction to the Company’s Contributed Surplus account, with effect from May 8 2025. The purpose of this proposal is primarily to increase the ability of the Company to make distributions to its Shareholders.

In May 2025, also at the AGM, the Company's shareholders approved the delisting of the Company's common shares from the OSE and authorised the Board of Directors to take steps to implement the delisting including filing an application to the OSE. The Board believes that the current corporate governance framework of the Company, the NYSE listing rules and SEC regulations will sufficiently protect the interest of the shareholders. The Company will maintain its register with Euronext Securities Oslo (the "ESO Register" formerly known as Verdipapirsentralen or VPS) for the OSE shares for a period of at least six months from the effective date of the Delisting, to enable ESO Register shareholders to transfer their shares to the US market, as well as continue to accommodate migration of the shares from the ESO Register into shares which may be traded on the NYSE. Subsequently, in June 2025, the Company filed an application to the OSE for the delisting. The OSE accepted the application and announced that Company's common shares will be delisted as of September 16, 2025 and the last day of listing will be September 15, 2025.

Furthermore, Mikkel Storm Weum was elected as a Director of the Company at the 2025 AGM.

Mikkel Storm Weum has served as a director of the Company since May 2025 and also serves as director in Seatankers Management AS, responsible for Sale and Purchase, Newbuildings and Projects. Mr. Weum also serves as Senior Vice President, Business Development in SFL Management AS since 2018. Prior to joining SFL Corporation Ltd. and Seatankers, Mr. Weum worked as Vice President, Head of Commercial in Teekay Offshore working with Shuttle Tankers and Floating Offshore storage. Mr. Weum holds a Master’s degree in Naval Architecture from Newcastle University and a MSc in Shipping Trade and Finance from Cass Business School, City University.

RESULTS OF OPERATIONS

Six months ended June 30, 2025 compared to the six months ended June 30, 2024

Amounts included in the following discussion are derived from our unaudited condensed consolidated financial statements for the six months ended June 30, 2025 and 2024.

FLEX LNG Ltd.

Vessel operating revenues

(unaudited figures in thousands of $)	Six months ended
	June 30,
	2025	2024
Vessel operating revenues	174,420	174,932

Vessel operating revenues decreased by $0.5 million to $174.4 million in the six months ended June 30, 2025, as compared to the six months ended June 30, 2024. The decrease in revenue is due to the decline in spot market rates, which affected the variable rate contract for Flex Artemis, as well as a lower rate of hire achieved for Flex Constellation, as she was deployed in the short term market from the first quarter of 2025. This is offset by the positive revenue effect arising from the amendment to the time charter contracts for Flex Resolute and Flex Courageous in November 2024. In addition, the Company recorded revenue of $3.6 million related to European Union Allowances ("EUAs") in the first and second quarter of 2025. An equivalent amount has been recorded under voyage expenses for the period.

Voyage expenses

(unaudited figures in thousands of $)	Six months ended
	June 30,
	2025	2024
Voyage expenses	(4,956)	(1,302)

Voyage expenses, which include voyage specific expenses, broker commissions and bunkers consumption, increased by $3.7 million to $5.0 million in the six months ended June 30, 2025, as compared to the six months ended June 30, 2024. The increase in voyage expenses is due to the accrual of $3.6 million in relation to the obligation to settle EUAs under the EU Emission Trading System ("EU ETS"). An equivalent amount has been recorded under Vessel operating revenues for the period.

(unaudited figures in thousands of $)	Six months ended
	June 30,
	2025	2024
Vessel operating expenses	(36,288)	(34,485)

Vessel operating expenses increased by $1.8 million to $36.3 million in the six months ended June 30, 2025, as compared to the six months ended June 30, 2024. The increase in vessel operating expenses is due to higher costs related to crew changes and costs incurred for auxiliary engine maintenance as a result of reaching running hour milestones.

(unaudited figures in thousands of $)	Six months ended
	June 30,
	2025	2024
Administrative expenses	(4,454)	(5,261)

Administrative expenses decreased by $0.8 million to $4.5 million in the six months ended June 30, 2025, as compared to the six months ended June 30, 2024.

FLEX LNG Ltd.

(unaudited figures in thousands of $)	Six months ended
	June 30,
	2025	2024
Depreciation	(37,541)	(37,455)

Depreciation increased by $0.1 million to $37.5 million in the six months ended June 30, 2025, as compared to the six months ended June 30, 2024.

(unaudited figures in thousands of $)	Six months ended
	June 30,
	2025	2024
Interest income	2,132	2,059

Interest income increased by $0.1 million to $2.1 million in the six months ended June 30, 2025, as compared to the six months ended June 30, 2024.

Interest expense

(unaudited figures in thousands of $)	Six months ended
	June 30,
	2025	2024
Interest expense	(46,433)	(53,806)

Interest expense decreased by $7.4 million to $46.4 million in the six months ended June 30, 2025, as compared to the six months ended June 30, 2024. The decrease in interest expense is due to the decline in average 3-month SOFR in the first and second quarter of 2025 compared to the first and second quarter of 2024. This decrease was also due to the reduction in average debt drawn down during the period, as a result of refinancing of loan facilities in the third and fourth quarter of 2024.

Extinguishment costs of long-term debt

(unaudited figures in thousands of $)	Six months ended
	June 30,
	2025	2024
Extinguishment costs of long-term debt	(1,630)	—

Extinguishment costs of long-term debt were $1.6 million in the six months ended June 30, 2025, compared to nil in the six months ended June 30, 2024. This relates to the write-off of unamortized debt issuance costs of $1.0 million and prepayment fees of $0.6 million in relation to the extinguishment of debt for Flex Courageous under the $320 Million Sale and Leaseback.

FLEX LNG Ltd.

Loss on derivatives

(unaudited figures in thousands of $)	Six months ended
	June 30,
	2025	2024
Gain/(loss) on derivatives	(8,637)	10,781

The Company recorded a net loss on derivatives of $8.6 million in the six months ended June 30, 2025, which includes a net unrealized loss of $16.7 million and a net realized gain on derivatives of $8.0 million. This compares to a net gain on derivatives of $10.8 million in the six months ended June 30, 2024, comprising a net unrealized gain of $2.6 million and a net realized gain of $13.4 million. The unrealized gain or loss on derivatives is primarily driven by the changes in the fair value of the interest rate swaps. The realized gain/(loss) on derivative settlements will be affected by changes in the shorter term floating rate of interest compared to the respective agreement's fixed rate of interest.

Other financial items

(unaudited figures in thousands of $)	Six months ended
	June 30,
	2025	2024
Other financial items	(117)	(352)

The Company recorded an expense of $0.1 million in relation to other financial items in the six months ended June 30, 2025, compared to an expense of $0.4 million in the six months ended June 30, 2024.

LIQUIDITY AND CAPITAL RESOURCES

We operate in a capital-intensive industry and have financed the purchase of the vessels in our Fleet through a combination of cash generated from operations, equity capital and borrowings under our financing agreements. Payment of amounts outstanding under our debt agreements, and all other commitments that we have entered into are made from the cash available to us.

Cash

As of June 30, 2025, we had an aggregate of cash and cash equivalents and restricted cash of $412.7 million, a decrease of $24.5 million, compared to an aggregate of $437.2 million as of December 31, 2024. In the six months ended June 30, 2025, the changes in cash consisted of $67.1 million provided by operating activities and $92.0 million used in financing activities, and $0.5 million used as a result of the effect of exchange rate changes on cash.

Financing information

Flex Courageous Sale and Leaseback

In May 2025, the Company signed and completed a sale and leaseback agreement with an Asian-based lease provider for the vessel, Flex Courageous (the "Flex Courageous Sale and Leaseback"). Under the terms of the agreement, the vessel was sold for a consideration of $175.0 million, with a bareboat charter back of approximately 10 years. The lease is repaid on an age-adjusted repayment profile1 of approximately 22 years. The Company has the first option to terminate the lease and repurchase the vessel at fixed price after approximately 7 years. The bareboat lease is comprised of a fixed interest element and a floating interest element based on Term SOFR, plus a margin. The Company repaid the full amount outstanding of $129.6 million for Flex Courageous under the $320 Million Sale and Leaseback. As a result of this re-financing, the Company received net cash proceeds of approximately $43.0 million.

1 The age-adjusted repayment profile is a metric that we use to calculate the repayment period of our loans and leases to zero, in years and adjusted for the age of the financed vessel. The metric is used to compare repayment profiles between facilities on vessels of different ages.

FLEX LNG Ltd.

Interest Rate Swaps

In order to reduce the risks associated with fluctuations in interest rates, the Company has entered into interest rate swap transactions, whereby the floating rate has been swapped to a fixed rate of interest.

In March 2025, the Company completed one new swap transaction with a notional principal of $100.0 million, a fixed rate of 3.66% and a duration of 2 years.

In April 2025, the Company completed three new swap transactions with an aggregate notional principal of $150.0 million, a weighted average fixed rate of 3.46% and a weighted average duration of 1.8 years.

As of June 30, 2025, the Company has fixed interest rates on an aggregate notional principal amount of $850.0 million. The interest rate swaps have a fixed rate of interest based on SOFR, with a weighted average fixed interest rate of 2.33% and a weighted average duration of 3.0 years.

Loan Covenants

Certain of our financing agreements contain, among other things, the following financial and vessel covenants, which are tested quarterly. The most stringent of these require us (on a consolidated basis) to maintain:

•a book equity ratio of minimum 0.20 to 1.0;

•a positive working capital;

•minimum liquidity, including undrawn credit lines with a remaining term of at least six months, being the higher of:

i.$25 million;

ii.an amount equal to five per cent (5%) of our total interest bearing financial indebtedness net of any cash and cash equivalents; and

•collateral maintenance test, ensuring that the aggregate value of the vessels making up the facility in question exceeds the aggregate value of the debt commitment outstanding.

Our financing agreements discussed above contain, among other things, restrictive covenants which, to the extent triggered, would restrict our ability to:

i.declare, make or pay any dividend, charge, fee or other distribution (whether in cash or in kind) on or in respect of its share capital (or any class of its share capital);

ii.pay any interest or repay any principal amount (or capitalized interest) on any debt to any of its shareholders;

iii.redeem, repurchase or repay any of its share capital or resolve to do so; or

iv.enter into any transaction or arrangement having a similar effect as described in (i) through (iii) above.

Our secured credit facilities may be secured by, among other things:

•a first priority mortgage over the relevant collateralized vessels;

•a first priority assignment of earnings, insurances and charters from the mortgaged vessels for the specific facility;

•a pledge of earnings accounts generated by the mortgaged vessels for the specific facility; and

•a pledge of the equity interests of each vessel owning subsidiary under the specific facility.

A violation of any of the covenants contained in our financing agreements may constitute an event of default under the relevant financing agreement, which, unless cured within the grace period set forth under the financing agreement, if applicable, or waived or modified by our lenders, provides our lenders, by notice to the borrowers, with the right to, among other things, cancel the commitments immediately, declare that all or part of the loan, together with accrued interest, and all other amounts accrued or outstanding under the agreement, be immediately due and payable, enforce any or all security under the security documents, and/or exercise any or all of the rights, remedies, powers or discretion's granted to the facility agent or finance parties under the finance documents or by any applicable law or regulation or otherwise as a consequence of such event of default.

Furthermore, certain of our financing agreements contain a cross-default provision that may be triggered by a default under one of our other financing agreements. A cross-default provision means that a default on one loan would result in a default on certain of our other loans. Because of the presence of cross-default provisions in certain of our financing agreements, the refusal of any one lender under our financing agreements to grant or extend a waiver could result in certain of our indebtedness being accelerated, even if our other lenders under our financing agreements have waived covenant defaults under the respective agreements. If our secured indebtedness is accelerated in full or in part, it would be difficult for us to refinance our debt or

FLEX LNG Ltd.

obtain additional financing and we could lose our vessels and other assets securing our financing agreements if our lenders foreclose their liens, which would adversely affect our ability to conduct our business.

Moreover, in connection with any waivers of or amendments to our financing agreements that we have obtained, or may obtain in the future, our lenders may impose additional operating and financial restrictions on us or modify the terms of our existing financing agreements. These restrictions may further restrict our ability to, among other things, pay dividends, make capital expenditures or incur additional indebtedness, including through the issuance of guarantees. In addition, our lenders may require the payment of additional fees, require prepayment of a portion of our indebtedness to them, accelerate the amortization schedule for our indebtedness and increase the interest rates they charge us on our outstanding indebtedness.

As of June 30, 2025, we were in compliance with all of the financial covenants contained in our financing agreements.

Cash Flows

The following summarizes our cash flows from operating, investing and financing activities for the six months ended June 30, 2025 and 2024.

Net cash provided by operating activities decreased by $15.3 million to $67.1 million for the six months ended June 30, 2025, compared to $82.4 million for the six months ended June 30, 2024. This was primarily due to amounts paid and advanced for drydockings scheduled in 2025 and 2026. The Company has scheduled four drydockings in 2025, compared to two drydockings completed in 2024.

Investing Activities

Net cash used in investing activities was $0.0 million in the six months ended June 30, 2025, compared to $0.0 million in the six months ended June 30, 2024.

Financing Activities

Net cash used in financing activities was $92.0 million in the six months ended June 30, 2025, compared to $122.4 million provided by financing activities in the six months ended June 30, 2024.

Net cash used in financing activities in the six months ended June 30, 2025, primarily comprised of:

•Prepayment of $129.6 million, which was the outstanding amount relevant to Flex Courageous, under the $330 Million Sale and Leaseback and prepayment fees of $0.6 million related to the same;

•scheduled repayments of long-term debt amounting to $54.3 million;

•dividend payments of $81.1 million; and

•financing costs of $1.4 million in relation to the new Flex Courageous Sale and Leaseback.

FLEX LNG Ltd.

These items were partially offset by:

•closing proceeds of $175.0 million from the Flex Courageous Sale and Leaseback;

Net cash used in financing activities in the six months ended June 30, 2024, primarily consisted of $53.0 million of scheduled repayments of long-term debt and dividends of $80.7 million, offset by: $10.4 million in proceeds from the termination of derivative instruments.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our activities expose us to a variety of financial risks including market risk (including currency risk and interest rate risk), credit risk and liquidity risk. Our overall risk management program considers the unpredictability of financial markets and seeks to minimize potential adverse effects on our financial performance, in a cost-effective manner.

Interest rate risk

The Company is exposed to the impact of interest rate changes primarily through its floating-rate borrowings that require the Company to make interest payments based on SOFR. Significant increases in interest rates could adversely affect operating margins, results of operations and ability to service debt. The Company uses interest rate swaps to reduce its 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.

As of June 30, 2025, the Company's long-term debt which was at variable rates, net of the amount subject to interest rate swap agreements, was $818.4 million, which includes $413.7 million drawn under revolving credit facilities. Based on this, one percentage point increase in annual SOFR interest rates would increase its annual interest expense by approximately $8.2 million.

As of June 30, 2025, we had interest rate swap transactions, aimed at reducing the risks associated with fluctuations in interest rates, whereby the floating rate has been swapped to a fixed rate. The aggregate net notional principal of our interest rate swaps was $850.0 million. Please see “Note 10. Financial Instruments” to our unaudited interim condensed consolidated financial statements for additional details.

Foreign Currency Risk

The majority of our transactions, assets and liabilities are denominated in U.S. dollars, our functional currency. However, we incur expenditure in currencies other than the functional currency, mainly overhead costs in GBP and NOK. Historically, we have not hedged these exposures. There is a risk that currency fluctuations in transactions incurred in currencies other than our functional currency will have a negative effect on the value of our cash flows.

Inflation

Significant global inflationary pressures increase operating, voyage, general and administrative, and financing costs. Historically, shipping companies are accustomed to navigating in shipping downturns, coping with inflationary pressures and monitoring costs to preserve liquidity, as they typically encourage suppliers and service providers to lower rates and prices.

Liquidity Risk

We monitor the risk of a shortage of funds using a cash modeling forecast. This model considers the maturity of payment profiles and projected cash flows required to fund the operations. Historically funds have been raised via equity issuance, lease finance and loan finance. Market conditions can have a significant impact on the ability to raise equity, lease finance and loan finance. While equity issuance may be dilutive to existing shareholders, lease and loan finance will contain covenants and other restrictions.

Our objective is to maintain a balance between continuity of funding and flexibility through the raising of funds from investors.

FLEX LNG Ltd.

Credit Risk

We are exposed to credit risk, which is the risk that a counterparty will be unable to pay amounts in full when due. There is a concentration of credit risk with respect to cash and cash equivalents to the extent that substantially all of the amounts are carried with Skandinaviska Enskilda Banken AB ("SEB") (S&P Global rating: A+), Nordea Bank ABP, ("Nordea"), (S&P Global rating: AA-), Danske Bank AS ("Danske Bank") (S&P Global rating: A+) and DNB Bank ASA ("DNB") (S&P Global rating: AA-).

Price Risk

We are also subject, indirectly, to price risk related to the spot/short term charter market for chartering LNG carriers. Charter rates may be uncertain and volatile and depend upon, among other things, the natural gas prices, the supply and demand for vessels, arbitrage opportunities, vessel obsolescence and the energy market, which we cannot predict with certainty. Currently, no financial instruments have been entered into to reduce this risk.

Operational Risk

The operation of an LNG carrier has certain unique operational risks. Our vessels and their cargoes are at risk of being damaged or lost because of events such as marine disasters, bad weather, business interruptions caused by mechanical failures, grounding and fire, explosions and collisions, human error, war, terrorism, piracy, labor strikes, boycotts and other circumstances or events. These hazards may result in death or injury to persons, loss of revenues or property, higher insurance rates, damage to our customer relationships and market disruptions, delay or rerouting.

If our LNG carriers suffer damage, they may need to be repaired at a drydocking facility. The costs of drydocking repairs are unpredictable and may be substantial. We may have to pay drydocking costs that our insurance does not cover at all or in full. The loss of revenues while these vessels are being repaired and repositioned, as well as the actual cost of these repairs, may adversely affect our business and financial condition.

NOTES TO THE UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. GENERAL

FLEX LNG Ltd. ("FLEX LNG" or the "Company") is a limited liability company, originally incorporated in the British Virgin Islands in September 2006 and re-domiciled to Bermuda in June 2017. The Company is currently listed on the Oslo Stock Exchange and New York Stock Exchange under the symbol "FLNG". The Company's ordinary shares will delisted from the OSE on September 16, 2025. The Company's activities are focused on seaborne transportation of liquefied natural gas ("LNG") through the ownership and operation of fuel efficient, fifth generation LNG carriers. As of June 30, 2025, the Company had thirteen LNG carriers in operation.

2. ACCOUNTING POLICIES

Basis of accounting

The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the Company’s audited consolidated financial statements and, in the opinion of management, include all material adjustments, consisting only of normal recurring adjustments considered necessary for a fair statement of the Company's consolidated financial statements, in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The unaudited interim condensed consolidated financial statements should be read in conjunction with the annual consolidated financial statements and notes included in our Annual Report on Form 20-F for the year ended December 31, 2024, filed with the Securities and Exchange Commission (the "SEC") on February 28, 2025.

The unaudited interim condensed consolidated financial statements do not include all the disclosures required in an Annual Report on Form 20-F.

Significant accounting policies

The accounting policies adopted in the preparation of the unaudited condensed consolidated interim financial statements are consistent with those followed in the preparation of the Company’s annual financial statements for the year ended December 31, 2024.

3. RECENT ACCOUNTING PRONOUNCEMENTS

Recently issued accounting pronouncements are not expected to materially impact the Company.

4. EARNINGS PER SHARE

Basic earnings per share amounts are calculated by dividing the net income/(loss) by the weighted average number of ordinary shares outstanding during that period.

Diluted earnings per share amounts are calculated by dividing the net income/(loss) by the weighted average number of shares outstanding during the period, plus the weighted average number of ordinary shares that would be issued on conversion of all the dilutive potential ordinary shares into ordinary shares. If in the period there was a loss, then any potential ordinary shares have been excluded from the calculation of diluted loss per share, because the effects were anti-dilutive.

The following reflects the net income/(loss) and share data used in the earnings per share calculation.

Loan covenants

Certain of our financing agreements discussed above, have, amongst other things, the following financial and vessel covenants, as amended or waived, which are tested quarterly, the most stringent of which require us (on a consolidated basis) to maintain:

• a book equity ratio of minimum of 0.20 to 1.0;

F-9

FLEX LNG Ltd.

• a positive working capital;

• minimum liquidity, including undrawn credit lines with a remaining term of at least six months, being the higher of:

(i) $25 million; and (ii) an amount equal to five percent (5%) of our total interest bearing financial indebtedness net

of any cash and cash equivalents; and

•collateral maintenance test, ensuring that the aggregate value of the vessels making up the facility in question exceeds the aggregate value of the debt commitment outstanding.

As of June 30, 2025, all financial covenants have been met accordingly.

10. FINANCIAL INSTRUMENTS

In order to reduce the risks associated with fluctuations in interest rates, the Company has hedged exposures to interest rates using derivative instruments, which involves swapping floating rates of interest to fixed rates of interest. These instruments are not designated as hedges for accounting purposes.

Credit risk is the failure of the counterparty to perform under the terms of the derivative instrument. When the fair value of a derivative instrument is positive, the counterparty owes the Company, which creates credit risk for the Company. When the fair value of a derivative instrument is negative, the Company owes the counterparty, and, therefore, the Company is not exposed to the counterparty's credit risk in those circumstances. The Company minimizes counterparty credit risk in derivative instruments by entering into transactions with major banking and financial institutions. The derivative instruments entered into by the Company do not contain credit risk-related contingent features. The Company has not entered into master netting agreements with the counterparties to its derivative financial instrument contracts.

Market risk is the adverse effect on the value of a derivative instrument that results from a change in interest rates, currency exchange rates or commodity prices. The market risk associated with interest rate contracts is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken.

The Company assesses interest rate risk by monitoring changes in interest rate exposures that may adversely impact expected future cash flows and by evaluating economical hedging opportunities.

In order to reduce the risk associated with fluctuations in interest rates, the Company has interest rate swap agreements, whereby it receives a floating and pays a fixed rate of interest, on an aggregate net notional principal of $850.0 million as of June 30, 2025 (December 31, 2024: $635.0 million).

In March 2025, the Company completed one new swap transaction with a notional principal of $100.0 million, a fixed rate of 3.66% and a duration of 2 years.

In April 2025, the Company entered into three interest rate swap agreements for an aggregate notional principal of $150.0 million. The Company will receive a weighted average fixed interest of 3.46% and will pay a floating interest based on SOFR for a weighted average duration of 1.8 years.

Our interest rate swap contracts as of June 30, 2025, of which none are designated as hedging instruments, are summarized as follows:

At June 30, 2025	23,668	(250)	23,418

11. FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES

The principal financial assets of the Company at June 30, 2025 and December 31, 2024 consist of cash and cash equivalents, restricted cash, other current assets, receivables due from related parties and derivative instruments receivable amongst other less significant items. The principal financial liabilities of the Company consist of payables due to related parties, accounts payable, other current liabilities, derivative instruments payable and long-term debt.

The fair value measurements requirement applies to all assets and liabilities that are being measured and reported on a fair value basis. The assets and liabilities carried at fair value should be classified and disclosed in one of the following three categories based on the inputs used to determine its fair value:

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.

The fair value of the Company's cash and cash equivalents and restricted cash approximates their carrying amounts reported in the accompanying consolidated balance sheets.

The fair value of other current assets, receivables from related parties, payables due to related parties, accounts payable and other current liabilities approximate their carrying amounts reported in the accompanying consolidated balance sheets.

The fair value of floating rate debt has been determined using Level 2 inputs and is considered to be equal to the carrying value since it bears variable interest rates, which are reset on a quarterly or semi-annual basis. Carrying value of the floating rate debt is shown net deduction of debt issuance cost, while fair value of floating rate debt is shown gross.

15. SHARE BASED COMPENSATION

In June 2025, the Company issued 182,805 synthetic share options to members of top management and key personnel. The synthetic share options have a five-year term from June 24, 2025, with a three-year vesting period, whereby: 33% will vest after one year; 33% will vest after two years; and the remaining balance will vest after three years. The options have a strike price of $23.75. The strike price will be adjusted for any distribution of dividends made before the relevant options expire. The synthetic options granted to the CEO and the CFO are subject to a cap on maximum annual gain equal to two times the annual base salary at the time of exercise of the synthetic options. The synthetic options will be settled in cash based on the difference between the market price of the Company’s shares and the strike price on the date of exercise, and as such, have been classified as a liability.

The synthetic options have an estimated expected life of 2.5 years. The risk-free interest rate was estimated using the interest rate on three year U.S. treasury zero coupon issues. The volatility was estimated using historical share price data. The dividend yield was estimated at 0% as the strike price is reduced by all dividends declared by the Company from the date of grant to the exercise date. It was assumed that all of the options granted will vest. The synthetic options had a fair value of $0.92 million as of June 30, 2025.

As at June 30, 2025, the Company had 182,805 outstanding non-vested share options (December 31, 2024: 20,000), with a weighted average adjusted strike price of $23.75 (December 31, 2024: $15.87) and a weighted average remaining contractual term of 5.0 years (December 31, 2024: 2.4 years).

The number of outstanding vested share options as at June 30, 2025 was 20,000 (December 31, 2024: nil) with a weighted average adjusted strike price of $15.12 and a weighted average remaining contractual term of 1.9 years.

Adjusted strike price refers to the fact that the strike price of each option is adjusted for dividends paid since the grant date of the option in line with the Company's share option scheme.

The $180 Million Facility has a 15.5 year tenor and an interest rate of SOFR plus a margin of 165 basis points. The repayment of the facility is based on a 25 year age adjusted repayment profile1 for the first 7.5 years, and thereafter follows a 22 year profile until maturity, when the facility is fully repaid. In August 2025, we prepaid the full amount outstanding relevant to Flex Constellation, under the $320 Million Sale and Leaseback facility. The new facility is expected to be drawn down in September 2025.

In August 2025, we signed a sale and leaseback agreement with an Asian-based lease provider for the vessel, Flex Resolute. Under the terms of the agreement, the vessel will be sold for a consideration of $175.0 million, with a bareboat charter back of approximately 10 years. The lease is repaid on an age-adjusted repayment profile1 of approximately 21 years. The Company has the first option to terminate the lease and repurchase the vessel at fixed price after approximately 7 years. The bareboat lease is comprised of a fixed interest element and a floating interest element based on Term SOFR, plus a margin. The Company will repay the full amount outstanding under the Flex Resolute $150 Million Facility. The new financing is expected to be completed in September 2025, subject to final documentation and customary closing conditions.
