A summary of key events:

•Declared a dividend of $0.75 per share for the fourth quarter of 2025.

•Achieved a Time Charter Equivalent rate of $70,119 per day for the fourth quarter of 2025.

Flex LNG Ltd. Fourth Quarter Results 2025

Marius Foss, CEO, commented:

“We are pleased to deliver financial performance for 2025 in line with our guidance. Our Time Charter Equivalent rate for the fleet came in at $71,728/day for the full-year 2025, thus in line with our guidance of $71,000 to 72,000/day. Adjusted EBITDA in 2025 was $251.1 million, slightly ahead of our guidance of ~$250 million. Following extensive refinancing initiatives in 2024 and 2025, we are now realizing tangible benefits. Full-year 2025 interest expenses declined to $92.6 million, down $13 million from 2024, driven by improved loan margins, lower base rates, and proactive management of our revolving credit facilities. Adjusted net income in the fourth quarter was $23.3 million, contributing to FY2025 adjusted net income of $101.1 million, with adjusted EPS of $1.87 per share.

The long-term LNG story remains compelling, and we view 2025 as the start of the third wave of new liquefaction capacity coming online. In 2025, global LNG exports grew by approximately 4% year-on-year, reaching 429 million tons ("MT"). North American projects were a major driver of this growth, with 25% growth year-on-year. Momentum in global project development also picked up, with 70 million tons per annum ("MTPA") of new projects reaching FID during 2025, bringing total capacity under construction to around ~200 MTPA.

The short- to medium-term outlook for LNG shipping is expected to be impacted by deliveries of newbuildings ahead of liquefaction projects coming on stream. We anticipate continued volatility in the spot market over the next 12–18 months. In this period our contract backlog, currently a minimum of 50 years and potentially extending to 75 years if charterers exercise all extension options, provides us with earnings visibility. In 2026 we will remain exposed to a softer spot market for up to three open vessels, including the redelivery of Flex Aurora later in the first quarter of 2026.

Our 2026 financial guidance reflects the current soft market for our spot exposed ships, with wider ranges for TCE, revenues, and adjusted EBITDA. At the same time, we have strengthened our balance sheet to navigate these conditions. We completed three refinancings worth $530 million in 2025, enabling us to release $137 million in net cash proceeds, while at the same time both lowering our interest costs and increasing our debt maturity profile. As a result, we have no debt maturities before 2029, and we closed the year with a robust cash position of $448 million.

We are committed to shareholder return, and the Board has declared an ordinary quarterly dividend of $0.75 per share. This is our eighteenth ordinary quarterly dividend of $0.75 per share; and when adding special dividends, we will have paid out approximately $770 million of dividends to our shareholders since 2021."

Quarterly dividends

On February 10, 2026, the Company’s Board of Directors declared a cash distribution for the fourth quarter of 2025 of $0.75 per share. The distribution will be made from the Company’s Contributed Surplus account, which consists of previously paid in share premium transferred from the Company’s Additional Paid In Capital account. The dividend will be paid on or around March 12, 2026. The record date and ex-dividend date on the New York Stock Exchange ("NYSE") will be February 27, 2026.

Flex LNG Ltd. Fourth Quarter Results 2025

Results for the three months ended December 31, 2025

The Company recorded vessel operating revenues of $87.5 million1 for the fourth quarter 2025, compared to $85.7 million in the third quarter 2025. Revenue for the quarter was positively impacted by the increased number of available days of two vessels, Flex Amber and Flex Artemis, which underwent drydockings during the third quarter 2025. This was partially offset by a decrease in revenue generated by Flex Constellation, due to a reduction in the charter hire rate. The TCE rate2 was $70,119 per day for the fourth quarter 2025, compared to $70,921 per day for the third quarter 2025. For the year ended December 31, 2025, the TCE rate2 was $71,728 per day.

Vessel operating expenses were $19.8 million in the fourth quarter 2025, compared to $18.8 million in the third quarter 2025. Operating Expenses ("Opex") per day2 was $16,582 for the fourth quarter 2025, compared to $15,682 for the third quarter 2025. The increase in vessel operating expenses is primarily due to higher auxiliary engine maintenance costs, as a greater number of vessels reached scheduled running hour milestones during the quarter. For the year ended December 31, 2025, the Opex per day2 was $15,780.

The Company recorded a net gain on derivatives of $1.4 million in the fourth quarter 2025, which includes a net unrealized loss of $1.7 million, as a result of the change in fair value of our interest rate swap derivatives and a net realized gain of $3.1 million on interest rate swap settlements in the period.

Net income for the fourth quarter 2025 was $21.6 million and basic earnings per share were $0.40, compared to a net income of $16.8 million and basic earnings per share of $0.31 for the third quarter 2025. Adjusted net income2 was $23.3 million for the fourth quarter 2025, compared to $23.5 million for the third quarter 2025.

As of December 31, 2025, the book value of vessels was $2,102.5 million, compared to $2,119.2 million as at September 30, 2025. The movement includes depreciation of $19.6 million and additions of $3.0 million in relation to vessel drydockings.

As of December 31, 2025, total long-term debt was $1,848.2 million, compared to $1,874.6 million as at September 30, 2025. The decrease in debt is due to the regular debt repayments which occurred during the fourth quarter 2025.

Cash and cash equivalents as of December 31, 2025 was $447.6 million. This includes fully drawn revolving tranches under the $270 Million Facility, $290 Million Facility and the Flex Enterprise $150 Million Facility.

As at December 31, 2025, total equity was $719.3 million compared to $738.3 million as at September 30, 2025. This decrease in equity mainly consists of distributions paid of $40.6 million, offset by net income of $21.6 million.

1 $85.4 million excluding EUAs.

2 TCE rate, Adjusted net income and Opex per day are non-GAAP measures as defined under SEC Regulation G. A reconciliation to the most directly comparable GAAP measure is included at the end of this earnings report.

Business Update and Fleet Overview

Flex Volunteer completed her scheduled drydocking in January 2026, following the redelivery from her long-term charter. She is currently being marketed for short and long-term contracts. Flex Freedom and Flex Vigilant are scheduled for docking in the first quarter and the second quarter of 2026.

The charterer of Flex Aurora elected not to utilize their extension option, and the vessel is expected to be re-delivered from the existing contract late in the first quarter of 2026. Following the re-delivery, the vessel will be marketed for short and long-term contracts.

Flex Artemis operated in the spot market during the quarter and is expected to continue trading in the spot market, while being marketed for short and long-term contracts.

Flex Constellation currently operates on a short-term charter contract and she is scheduled to commence the new 15-year time charter in early March 2026 in direct continuation of the current charter.

At the date of this report, the firm contract coverage is 77.6% for the remainder of 2026, and the aggregate firm contract backlog for the fleet is 50 years, which could increase to 75 years including extension options.

We achieved technical uptime on our vessels of 100% in the fourth quarter 2025 . The following table sets forth an overview of our fleet as of February 11, 2026:

(1) As used in this report, "HO" means Hanwha Ocean (formerly known as Daewoo Ship building and Marine Engineering Co. Ltd.), "SHI" means Samsung Heavy Industries, and "HSHI" means Hyundai Samho Heavy Industries Co. Ltd. Each shipyard is located in South Korea.

(2) "MEGI" refers to M-type Electronically Controlled Gas Injection propulsion systems and "X-DF" refers to Generation X Dual Fuel propulsion systems. "FRS" and "PRS" refers to Full Re-liquefaction Systems or Partial Re-liquefaction Systems, respectively.

(3) The expiration of our charters is considered the firm period known to the Company as of February 11, 2026, however these are generally subject to re-delivery windows ranging from 15 to 45 days before or after the expiration date.

(4) Where charterers have extension option(s) to be declared on a charter; the expiration provided assumes all extension options have been declared by the charterer for illustrative purposes.

LNG Market Update

Shipping market conditions remained volatile in 2025, with high tonnage availability acting as the dominant bearish factor through much of the year. Oversupply resulted in the widespread layup and prolonged idleness of steam and TFDE vessels, gradually eroding effective capacity. This attrition supported a partial rebalancing in the second half of 2025, contributing to a sharp but short-lived rally in the fourth quarter 2025, during which two-stroke spot rates briefly reached $125,000/day. The rally was supported by stronger U.S. exports and incremental Nigerian and Algerian cargoes, tightening prompt Atlantic availability. However, rising relet volumes quickly weighed on rates. Average spot rates for modern two-stroke vessels in FY2025 were around $37,000/day, down from $53,000/day in 2024, and are currently quoted near $20,000/day. The recent decline reflects continued vessel oversupply and temporary disruptions to U.S. LNG exports, including feedgas shortages and weather-related outages.

Of the 18 newbuilds ordered in the fourth quarter 2025 for delivery in the second half of 2028–2029, around 13 are secured on 10–20 year contracts, with five uncommitted. Full-year contracting slowed materially, with 35 new orders versus 79 in 2024. Korean yard prices are quoted at around $250 million per vessel, with Chinese yards offering a $10–20 million discount.

Fleet growth accelerated in 2025, with 79 deliveries versus 60 in 2024, including 23 in the fourth quarter 2025. A further 6 vessels were delivered in January 2026, leaving an orderbook of ~285 vessels (~39% of the fleet). Shipbrokers expect 90–95 deliveries in 2026, with 35–40 vessels uncommitted. Weak trading for older steam vessels accelerated fleet rationalization, with a record 15 recyclings in 2025. This trend is expected to continue in 2026, partially offsetting newbuild inflows.

On the LNG cargo side, global supply growth accelerated to 4.0% in 2025, the fastest pace in three years, reaching a record 429 million tons ("MT"). Incremental volumes were skewed toward the Atlantic Basin, driven primarily by North American capacity additions and optimisation. The rapid ramp-up of Plaquemines LNG, alongside new supply from LNG Canada, Altamira, and Corpus Christi Midscale, accounted for the majority of the net growth, while debottlenecking at Freeport pushed production above nameplate capacity. US LNG exports increased by 22 MT year-on-year. Outside North America, supply growth was limited, with Russian exports declining by 2 MT due to sanctions-related constraints, Egyptian exports remaining subdued due to domestic demand, and Australian exports falling by 3.5 MT amid heavy maintenance.

LNG import growth closely mirrored the export profile, with the Atlantic Basin absorbing most incremental volumes. Europe emerged as the primary demand centre, importing a record 125.3 MT, equal to 24 MT year-on-year growth, as low storage levels and the replacement of Russian flows increased LNG reliance, particularly from the US. In contrast, Chinese LNG imports declined 15 MT year-on-year due to higher pipeline imports, rising domestic production, and mild weather, reducing Pacific trade flows. Excluding China, Asian demand was broadly flat, with gains in smaller markets offset by policy-driven and price-sensitive declines elsewhere. As a result, the alignment of Atlantic-based supply growth with Atlantic demand expansion limited tonne-mile growth in 2025, despite strong headline trade growth.

APPENDIX B - Reconciliation of Non-GAAP Measures

In this appendix we present additional information and measures intended to supplement investors’ understanding of our operating performance, by providing information regarding our ongoing performance that exclude items we believe do not directly affect our core operations and enhancing the comparability of our ongoing performance across periods. These measures are not items recognized by U.S. GAAP, and should not be considered in isolation or used as alternatives to our operating performance or liquidity calculated in accordance with U.S. GAAP. Our management considers these measures to be useful to investors, because such performance measures provide information regarding the profitability of our core operations and facilitate comparison of our operating performance to that of our peers. Additionally, our management use these measures when reviewing the Company’s operating performance. While we believe these measures are useful to investors, the definitions used by us may not be comparable to similar measures used by other companies.

(A) Reconciliation of Net Income to EBITDA and Adjusted EBITDA (Earnings before Interest Taxes Depreciation and Amortization) EBITDA is defined as net income plus net interest expense, write-off of debt issuance costs, income tax expense / (benefit) and depreciation and amortization. Adjusted EBITDA represents EBITDA adjusted to exclude the items set forth in the table below, which represent items that we believe are not indicative of the ongoing performance of our core operations. EBITDA and Adjusted EBITDA are used by analysts in the shipping industry as common performance measures to compare results across peers.

The table below reconciles net income, the most directly comparable U.S. GAAP measure, to EBITDA and Adjusted EBITDA.

Flex LNG Ltd. Fourth Quarter Results 2025

(B) Reconciliation of Net Income to Adjusted Net Income and Adjusted Earnings Per Share Adjusted net income represents earnings before write-off and accelerated amortization of unamortized loan fees, fees in relation to the extinguishment of long-term debt, foreign exchange gains/loss and Change in assets/liabilities of derivative instruments. Adjusted Earnings Per Share ("EPS") represents earnings attributable to shareholders of the Company adjusted for the above items, divided by the weighted average number of shares outstanding. We believe that adjusted net income and adjusted EPS assist our management and investors in (i) understanding and analyzing the results of our operating and business performance, (ii) selecting between investing in us and other investment alternatives and (iii) monitoring our ongoing financial and operational strength in assessing whether to purchase and/or to continue to hold our common shares.

(C) Reconciliation of Total Operating Revenues to Time Charter Equivalent Income and Time Charter Equivalent Rate Time charter equivalent rate ("TCE rate") represents the weighted average daily TCE income of our entire operating fleet. TCE rate is a measure of the average daily income performance. Our method of calculating TCE rate is determined by dividing TCE income by onhire days during a reporting period. We define TCE income as vessel operating revenues less voyage expenses. Onhire days are calculated on a vessel by vessel basis and represent the net of available days and offhire days for each vessel (owned or chartered in) in our possession during a reporting period. Available days for a vessel during a reporting period is the number of days the vessel (owned or chartered in) is in our possession during the period. Offhire days for a vessel during a reporting period is the number of days the vessel is in our possession during the period but is not operational as a result of unscheduled repairs, scheduled drydockings or special or intermediate surveys and lay-ups, if any.

Flex LNG Ltd. Fourth Quarter Results 2025

The table below reconciles Vessel operating revenues, the most directly comparable U.S. GAAP measure, to Time Charter Equivalent income.

(D) Reconciliation of Vessel operating expenses to Operating Expenses per day Operating Expenses ("Opex") per day represents the weighted average daily vessel operating expenses of our entire operating fleet. Opex per day is a measure of the average daily operating performance. Our method of calculating Opex per day is determined by dividing vessel operating expenses by the available days during a reporting period. Available days for a vessel during a reporting period is the number of days the vessel (owned or chartered in) is in our possession during the period. Consistent with general practice in the shipping industry, we use Opex per day as a measure to compare Opex to compare the relative performance of the Companies technical performance with other industry peers.

The table below reconciles Vessel Operating Expenses to Opex per day.
