This presentation contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended (the "Securities Act") and Section 21E of the Exchange Act. Forward-looking statements give our current expectations or forecasts of future events. They include statements regarding our future operating and financial performance. Although we believe the expectations and forecasts reflected in these and other forward-looking statements are reasonable, we can give no assurance they will prove to have been correct. They can be affected by inaccurate assumptions or by known or unknown risks and uncertainties, many of which are described under "Risk factors" in our Annual Report on Form 10-K for the year ended December 31, 2022 and Quarterly Reports on Form 10-Q filed during 2022 available on our website and at www.sec.gov. You should understand that such risk factors, could affect our future results and could cause those results or other outcomes to differ materially from those expressed or implied in the forward-looking statements relating to: (1) amount, nature and timing of capital expenditures; (2) drilling of wells and other planned exploitation activities; (3) timing and amount of future production of oil and natural gas; (4) increases in production growth and proved reserves; (5) operating costs such as lease operating expenses, administrative costs and other expenses; (6) our future operating or financial results; (7) cash flow and anticipated liquidity; (8) our business strategy, including expansion into the deep shelf and the deepwater of the Gulf of Mexico, and the availability of acquisition opportunities; (9) hedging strategy; (10) exploration and exploitation activities and property acquisitions; (11) marketing of oil and natural gas; (12) governmental and environmental regulation of the oil and gas industry; (13) environmental liabilities relating to potential pollution arising from our operations; (14) our level of indebtedness; (15) timing and amount of future dividends; (16) industry competition, conditions, performance and consolidation; (17) natural events such as severe weather, hurricanes, floods, fire and earthquakes; and (18) availability of drilling rigs and other oil field equipment and services.

The filings with the Securities and Exchange Commission (the "SEC") are hereby incorporated herein by reference and qualify the presentation in its entirety. This presentation does not constitute an offer to sell or the solicitation of an offer to buy any of our securities, nor shall there be any sale of securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction. Cautionary Note Regarding Hydrocarbon Quantities The SEC permits oil and gas companies, in their filings with the SEC, to disclose only proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions, and on an optional basis, probable and possible reserves meeting SEC definitions and criteria. The Company does not include probable and possible reserves in its SEC filings. This presentation includes information concerning probable reserves quantities compliant with PRMS/SPE guidelines and related PV-10 values that are different from quantities of such non-proved reserves that may be reported under SEC rules and guidelines. In addition, this presentation includes Company estimates of resources and "EURS" or "economic ultimate recoveries" that are not necessarily reserves because no specific development plan has been committed for such recoveries. Recovery of estimated probable reserves and estimates of resources and EUR's and recoverable resources, are inherently more speculative than recovery of proved reserves. PV-10 of reserves includes projected revenues, estimated production costs and estimated future development costs. Unless otherwise stated, PV-10 excludes cash flows for asset retirement obligations, general and administrative expenses, derivatives, debt service and income taxes. Standardized measure or the PV-10 from our proved or 2P oil and natural gas reserves should not be viewed as representative of the current market value of our estimated oil and natural gas reserves. See Appendix for more information. 2 W&T OFFSHORE | NYSE:WTI W&T OFFSHORE#3Non-GAAP Measures This presentation includes certain financial measures that are not calculated in accordance with U.S. generally accepted accounting principles ("GAAP"). These measures include (i) Net Debt, (ii) Adjusted Net Income (Loss), (iii) Adjusted EBITDA and (iv) Free Cash Flow. These non-GAAP financial measures are not measures of financial performance prepared or presented in accordance with GAAP and may exclude items that are significant in understanding and assessing our financial results. Therefore, these measures should not be considered in isolation, and users of any such information should not place undue reliance thereon. Please refer to the slides titled "Non-GAAP Reconciliations" under the Appendix to this presentation for a reconciliation of these measures to the most directly comparable GAAP measures and WTI's definitions (which may be materially different than similarly titled measures used by other companies) of these measures as well as certain additional information regarding these measures. WTI believes the presentation of these metrics may be useful to investors because it supplements investors' understanding of its operating performance by providing information regarding its ongoing performance that excludes items it believes do not directly affect its core operations.

The Company defines Net Debt as current and long-term debt, net of unamortized debt discounts, less cash and cash equivalents. The Company defines Net Leverage as Net Debt divided by the last 12 month's Adjusted EBITDA. Company management believes this presentation is relevant and useful because it helps investors understand W&T's operating performance and makes it easier to compare its results with those of other companies that have different financing, capital and tax structures. Adjusted EBITDA should not be considered in isolation from or as a substitute for net income, as an indication of operating performance or cash flows from operating activities or as a measure of liquidity. Adjusted EBITDA, as W&T calculates it, may not be comparable to Adjusted EBITDA measures reported by other companies. In addition, Adjusted EBITDA does not represent funds available for discretionary use. The Company defines Free Cash Flow as Adjusted EBITDA (defined above), less capital expenditures, asset retirement obligations and interest expense (all on an accrual basis). For this purpose, the Company's definition of capital expenditures includes costs incurred related to oil and natural gas properties (such as drilling and infrastructure costs and the lease maintenance costs) and equipment, furniture and fixtures, but excludes acquisition costs of oil and gas properties from third parties that are not included in the Company's capital expenditures guidance provided to investors. Company management believes that Free Cash Flow is an important financial performance measure for use in evaluating the performance and efficiency of its current operating activities after the impact of accrued capital expenditures, asset retirement obligations and interest expense and without being impacted by items such as changes associated with working capital, which can vary substantially from one period to another. There is no commonly accepted definition of Free Cash Flow within the industry. Accordingly, Free Cash Flow, as defined and calculated by the Company, may not be comparable to Free Cash Flow or other similarly named non-GAAP measures reported by other companies. While the Company includes interest expense in the calculation of Free Cash Flow, other mandatory debt service requirements of future payments of principal at maturity (if such debt is not refinanced) are excluded from the calculation of Free Cash Flow. These and other non- discretionary expenditures that are not deducted from Free Cash Flow would reduce cash available for other uses. The following tables present (i) a reconciliation of Total Debt to Net Debt and Net Leverage (ii) a reconciliation of the Company's net (loss) income, a GAAP measure, to Adjusted EBITDA and Free Cash Flow (iii) a reconciliation of cash flow from operating activities, a GAAP measure, to Free Cash Flow, as such terms are defined by the Company. 39 W&T OFFSHORE | NYSE:WTI W&T OFFSHORE#40NON-GAAP
