INFORMATION CONTAINED IN THIS FORM 6-K REPORT

    Attached hereto as Exhibit 1 is a copy of the press release issued by FLEX LNG Ltd (the "Company"), dated February 23, 2024, announcing the extension of the Time Charter for Flex Endeavour which was extended by 500 days from the third quarter of 2030 to the first quarter of 2032.

This Report on Form 6-K, excluding the commentary of Øystein Kalleklev, is hereby incorporated by reference into the Company’s Registration Statement on Form F-3 (File No. 333-268367) that was declared effective December 7, 2022 and the Company's Registration Statement on Form F-3 (registration No. 333-259962) that was declared effective October 14, 2021.

FORWARD-LOOKING STATEMENTS

Matters discussed in this Report on Form 6-K may constitute forward-looking statements. The Private Securities Litigation Reform Act of 1995 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. The Company desires to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and is including this cautionary statement in connection with this safe harbor legislation. The words "believe," "expect," "forecast," "anticipate," "estimate," "intend," "plan," "possible," "potential," "pending," "target," "project," "likely," "may," "will," "would," "should," "could" and similar expressions identify forward-looking statements.

The forward-looking statements in this Report on Form 6-K are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management’s examination of historical operating trends, data contained in the Company’s records and other data available from third parties. Although management believes that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies which are difficult or impossible to predict and are beyond the Company’s control, there can be no assurance that the Company will achieve or accomplish these expectations, beliefs or projections. As such, these forward-looking statements are not guarantees of the Company’s future performance, and actual results and future developments may vary materially from those projected in the forward-looking statements. The Company undertakes no obligation, and specifically declines any obligation, except as required by applicable law or regulation, to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. New factors emerge from time to time, and it is not possible for the Company to predict all of these factors. Further, the Company cannot assess the effect of each such factor on its business or the extent to which any factor, or combination of factors, may cause actual results to be materially different from those contained in any forward-looking statement.

In addition to these important factors, other important factors that, in the Company’s view, could cause actual results to differ materially from those discussed in the forward-looking statements include: unforeseen liabilities, future capital expenditures, the strength of world economies and currencies, general market conditions, including fluctuations in charter rates and vessel values, changes in demand in the LNG tanker market, the impact of public health threats and outbreaks of other highly communicable diseases, changes in the Company’s operating expenses, including bunker prices, dry-docking and insurance costs, the fuel efficiency of the Company’s vessels, the market for the Company’s vessels, availability of financing and refinancing, ability to comply with covenants in such financing arrangements, failure of counterparties to fully perform their contracts with the Company, changes in governmental rules and regulations or actions taken by regulatory authorities, including those that may limit the commercial useful lives of LNG tankers, customers' increasing emphasis on environmental and safety concerns, potential liability from pending or future litigation, general domestic and international political conditions or events, including the recent conflicts between Russia and Ukraine and between Israel and Hamas, business disruptions, including supply chain disruption and congestion, due to natural or other disasters or otherwise, potential physical disruption of shipping routes due to accidents, climate-related incidents, or political events, vessel breakdowns and instances of off-hire, and other factors, including those that may be described from time to time in the reports and other documents that the Company files with or furnishes to the U.S. Securities and Exchange Commission (“Other Reports”). For a more complete discussion of certain of these and other risks and uncertainties associated with the Company, please refer to the Other Reports.
