• Reported Net Income of $138.8 million or $0.96 per share in the fourth quarter of 2018, which was substantially greater than the Net Income of $23.4 million or $0.16 per share in the fourth quarter of 2017;

W&T Offshore, Inc. • Nine Greenway Plaza, Suite 300 • Houston, Texas 77046 • 713-626-8525 • www.wtoffshore.com

• Reported Adjusted Net Income for full year 2018 of $146.2 million or $1.01 per share, and $32.0 million or $0.22 per share in the fourth quarter of 2018, increases of 83% and 32% compared with the full-year and the fourth quarter of 2017, respectively;

• Generated significant Adjusted EBITDA of $82.3 million for the fourth quarter of 2018, up 13% from the same period in 2017, and $344.2 million for the full year 2018, up 28% from the full year 2017;

• Expanded Adjusted EBITDA margin to 59% for the full year 2018 compared with 55% in 2017;

• Successfully refinanced outstanding debt and reduced total debt principal outstanding from $903 million to $625 million on October 18, 2018; and

• Continued strong operational well results with six wells completed and brought online in 2018.

Tracy W. Krohn, W&T’s Chairman and Chief Executive Officer, stated, “We have a long history of success and growing value for our shareholders, and I am especially pleased with our achievements in 2018. This past year we were able to meaningfully increase reserves due to robust drilling results as well as through favorable well performance which continued to exceed our expectations. Our strong, stable production base generated significant cash flow providing us with the cash needed to bolster our financial position. We were able to completely refinance our debt, simplify our capital structure, reduce our total debt principal by over $200 million, extend debt maturities and establish a larger revolving credit facility. We also entered a drilling joint venture to accelerate the development of our high return inventory, lower our overall risk, and to maximize our financial flexibility which will enable us to actively pursue additional accretive acquisitions similar to the Heidelberg Field acquisition we completed in 2018.”

Mr. Krohn continued, “Entering 2019, our capital program will be focused on low risk, high return projects as we strive to continue the greater than 90% success rate we have achieved in drilling more than 40 wells since 2010. We will maintain our measured approach to drilling, fund all our capital expenditures with cash from operations and continue to generate significant free cash flow. We believe that we will be able to increase our production 2% to 3% versus our full year 2018 production rate of around 36,500 BOEPD, with modest total capital expenditures of around $120 million.”

“During the past 35 years, we have developed significant technical experience and have successfully discovered and produced properties on the conventional shelf and in the deep waters across the Gulf of Mexico. We believe we have assembled a premier set of assets that generates a solid foundation of cash flow with significant upside. As we look to the future, we believe that market conditions in the Gulf are very favorable for acquisitions. We will look at opportunities that add production, reserves and cash flow and believe that we are very well positioned with a stronger balance sheet, improved financial liquidity and a successful track record of making accretive acquisitions that will allow us to benefit from the current acquisition market. Our management team’s interests are aligned with those of our shareholders through our 33% stake in the Company’s equity. This alignment of interest ensures that we are truly incentivized to maximize shareholder value and mitigate risk, rather than simply focusing on shorter term metrics,” concluded Mr. Krohn.

For the fourth quarter of 2018, W&T reported net income of $138.8 million, or $0.96 per share. Excluding primarily a $55.3 million unrealized commodity derivative gain and a $47.1 millionnon-cash gain on debt refinancing, the Company’s Adjusted Net Income was $32.0 million, or $0.22 per share. In the fourth quarter of 2017, W&T reported Net Income of $23.4 million, or $0.16 per share, and Adjusted Net Income of $24.2 million or $0.17 per share. W&T reported Net Income for full year 2018 of $248.8 million, or $1.72 per share and Adjusted Net Income of $146.2 million, or $1.01 per share. For the full year 2017, W&T reported Net Income of $79.7 million, or $0.56 per share, and Adjusted Net Income of $79.7 million, or $0.56 per share.

Adjusted EBITDA totaled $82.3 million for the fourth quarter 2018, an increase of 13% compared to $72.9 million in the fourth quarter of 2017. The Company generated $344.2 million in Adjusted EBITDA for the full year 2018, an increase of 28% compared to $268.4 million in 2017. Adjusted EBITDA margin in 2018 was 59%, compared to Adjusted EBITDA margin of 55% for 2017.

Adjusted Net Income and Adjusted EBITDA arenon-GAAP financial measures, which are described in more detail and reconciled to net income, their most comparable GAAP measure, in the attached tables below under“Non-GAAP Information.”

Production, Prices and Revenues: Production for the fourth quarter of 2018 was 35.0 MBOEPD or 3.2 MMBOE, down slightly versus 3.5 MMBOE in the fourth quarter of 2017. Fourth quarter 2018 production was comprised of 1.7 million barrels of oil, 0.3 million barrels of natural gas liquids (“NGLs”) and 7.3 billion cubic feet (“Bcf”) of natural gas. Total liquids production comprised 62% of production in the fourth quarter of 2018 compared to 58% of production in the fourth quarter of 2017. Production for the fourth quarter of 2018 was near themid-point of production guidance despite the impact of hurricane, pipeline and facility downtime during the period.

3

For the full year 2018, production was 13.3 MMBOE, comprised of 6.7 million barrels of oil, 1.3 million barrels of NGLs, and 32.0 Bcf of natural gas. Full year 2017 production totaled 14.6 MMBOE and included 7.1 million barrels of oil, 1.4 million barrels of NGLs, and 36.8 Bcf of natural gas.

For the fourth quarter of 2018, W&T’s realized crude oil sales price was $62.94 per barrel, up 13% over the fourth quarter of 2017. The Company’s realized NGL sales price was $26.84 per barrel, down 3% from the same quarter in 2017 and its realized natural gas sales price was $3.83 per Mcf, up 30% from the fourth quarter of 2017. The Company’s combined average realized sales price for the quarter was $44.15 per Boe, which represents a 20% increase over the $36.79 per Boe sales price that was realized in the fourth quarter of 2017.

For the full year 2018, W&T’s realized crude oil sales price was $65.62 per barrel, its NGL sales price was $28.40 per barrel and its natural gas price was $3.11 per Mcf. The combined average sales price was $43.19 per Boe, or 31% higher than $33.02 per Boe sales price that was realized for full year 2017. For the full year 2017, W&T’s realized oil price was $48.13 per barrel, its NGL price was $23.35 per barrel and its natural gas price was $2.96 per Mcf.

Revenues for the fourth quarter of 2018 increased 11% to $143.4 million compared to $129.1 million in the fourth quarter of 2017, primarily driven by the increase in realized commodity sales price per Boe. For the full year 2018, revenues totaled $580.7 million, up 19% compared with $487.1 million in 2017, primarily due to improvements in commodity prices.

Lease Operating Expenses: Lease Operating Expense (“LOE”) which includes base lease operating expenses, insurance premiums, workovers and facilities maintenance, was $43.4 million in the fourth quarter of 2018 compared to $36.9 million in the fourth quarter of 2017. On a component basis for the fourth quarter of 2018, base lease operating expenses were $33.4 million, insurance premiums were $3.1 million, workovers were $2.3 million and facilities maintenance was $4.6 million.The year-over-year increase was driven by additional costs associated with the Heidelberg field acquisition, increased repair and facility work, additional acid stimulation and coil tubing cleanouts and higher insurance premiums for increased coverage.

4

For the full year 2018, LOE was $153.3 million, up 7% from $143.7 million in 2017 due to additional costs associated with the Heidelberg acquisition, increased insurance premiums for improved coverage and additional workover projects primarily at the Mahogany field. The acquisition of Heidelberg contributed 51% of the net increase in LOE in 2018 over 2017 .

Depreciation, Depletion, Amortization and Accretion (“DD&A”): DD&A, including accretion for asset retirement obligations, was $10.88 per Boe of production for the fourth quarter of 2018 compared to $11.25 per Boe for the fourth quarter of 2017. For the full year 2018, DD&A was $11.24 per Boe compared with $10.68 per Boe in 2017.

General and Administrative Expenses (“G&A”): G&A was $14.9 million for the fourth quarter of 2018, an increase of 4% compared to $14.4 million in the fourth quarter of 2017. For the full year 2018, G&A was $60.1 million, virtually flat with full year 2017 G&A of $59.7 million.

Derivative (Gain) Loss: In the fourth quarter of 2018, W&T recorded a net gain of $59.7 million on its outstanding commodity derivative contracts. This compared to a net loss of $0.6 million in the fourth quarter of 2017 on the derivative contracts that expired at the end of 2017. In the fourth quarter of 2018, W&T entered into additional derivative contracts for crude oil and natural gas, which consists primarily of crude oil contracts with a term of 18 months. A list of the Company’s current outstanding derivative positions are included in the tables below as well as in the Investor Relations section of W&T’s web site under the “Other Reports” tab.

Interest Expense:Interest expense, as reported in the income statement, in the fourth quarter of 2018 was $15.2 million compared with $11.3 million in the same period in 2017. For the full year 2018, interest expense totaled $48.6 million versus $45.5 million in 2017. Prior to the refinancing transaction in October 2018, a portion of interest expense was capitalized which lowered interest expense in the income statement in 2017 and from January 1 through October 18, 2018 as a result of accounting requirements related to the Company’s prior debt structure. After the refinancing transaction, all interest expense incurred was reported as expense in the income statement.

Gain on Exchange of Debt:The debt refinancing transaction in October of 2018 resulted in a $47.1 millionnon-cash gain in the fourth quarter of 2018. The $47.1 million gain was recorded as a result of the refinancing transaction, comprised of the write off of carrying value adjustments of the prior debt instruments and partially offset by premiums paid.

5

Income Tax: Income tax expense was $0.2 million in the fourth quarter of 2018 compared to an income tax benefit of $1.5 million in the fourth quarter of 2017.For the full year 2018, income tax expense was $0.5 million compared with an income tax benefit of $12.6 million in 2017. W&T is not currently forecasting any cash income tax expense for the foreseeable future, and the Company’s deferred expense is fully offset by a valuation allowance. Consequently, the effective tax rate for W&T is not meaningful.

At December 31, 2018, W&T had a current income tax receivable of $54.1 million. The receivable relates primarily to net operating loss (“NOL”) claims for the years 2012, 2013 and 2014 that were carried back to prior years and require a review by the U.S. Congressional Joint Committee on Taxation prior to the payment being made. W&T received a $11.1 million refund in the fourth quarter of 2018 and expects to receive the $54.1 million income tax receivable before the end of the second quarter of 2019.

Cash Flow:Net cash provided by operating activities for the twelve months ended December 31, 2018 was $321.8 million, an increase of 102% compared to $159.4 million for the twelve months ended December 31, 2017. The increase is primarily due to higher realized prices for crude oil and NGLs, lower spending on plug and abandonment activities and a $16.6 million cash advance by joint venture partners.

Balance Sheet and Liquidity: On October 18, 2018, W&T closed on a refinancing of all of its long-term debt and bank facility, which reduced total debt principal outstanding from $903 million to $625 million, simplified the capital structure and extended the maturities of the Company’s revolving credit facility and senior secured notes to 2022 and 2023, respectively, while maintaining strong liquidity.

The refinancing was largely accomplished by the issuance of $625 million of new 9.75% senior second lien notes due November 2023. The net proceeds from the issuance, along with cash on hand and minimal borrowings on the revolving credit facility were used to retire all of the Company’s previously outstanding senior notes.

Concurrently, the Company entered into a Sixth Amended and Restated Credit Agreement which provides for a revolving credit and letter of credit facility with an increased borrowing base initially set at $250 million. At December 31, 2018, the Company had $21 million borrowings on the revolving credit facility and $9.6 million of letters of credit outstanding.

6

Total liquidity on December 31, 2018 was $252.7 million, consisting of cash and cash equivalents of $33.3 million and $219.4 million of availability under W&T’s revolving bank credit facility.

Capital Expenditures: Total capital expenditures for oil and gas properties was $106.2 million for the full year of 2018 (excluding acquisitions), which was the same level as in 2017. In addition, the Company acquired a 9.375% interest in the Heidelberg field for $16.8 million in early 2018. During 2018, the Company completed the SS 359A-17 well, drilled and completed the SS 359A-5 ST well and the SS 359A-19 well, all at the Mahogany field; drilled and completed theA-10 ST well and theA-12 well at Viosca Knoll 823 (“Virgo”); and drilled and completed the ST 320A-2 well at Ewing Bank 910 field.

2019 CAPITAL INVESTMENT PROGRAM

Under current commodity pricing conditions, W&T expects to continue to focus on acquisitions and maintaining liquidity. The Company’s capital expenditure budget for 2019 is expected to be around $120 million, which excludes acquisitions. The 2019 capital program will be a mix of lower-risk, high-return oil focused projects and some higher-risk, higher-return projects that, assuming success, would be placed on production fairly quickly. In 2019, the Company also expects to spend about $25.0 million on asset retirement obligations (“ARO”) compared to $28.6 million spent on ARO in 2018.

OPERATIONS UPDATE

W&T is currently operating or participating in three active drilling programs in the Gulf of Mexico, as described below.

Ship Shoal 349 “Mahogany” (operated, shelf, 100% working interest): The SS 359A-19 well was completed in theT-Sand and brought online in late November. This well has thus far shown significantly higher rates of early production than anyT-Sand well drilled to date in the field with a productivity index that is more than double the best prior completion in the field. Productivity index is defined as the flow rate per unit of pressure drop and serves as an indication of the production potential of a well. A staged ramp up of the well is continuing with the well producing at a rate of 5,205 Boe per day as of February 15, 2019. The rig conducted a planned maintenance and repair program following the completion of theA-19 well. Additional well work activities are ongoing at the Mahogany field with a restart of the platform rig to drill theA-20 development well targeting theT-Sand set to begin in early second quarter of 2019.

7

Ewing Bank 910 Field Area(non-operated, deepwater, in JV Drilling Program):The ST 320A-2 well was completed and brought online in December 2018. Due to limited equipment capacity to handle vapor recovery on the ST 311 platform, the well was brought online at a curtailed rate of 3,400 Boe per day. The issue is expected to be resolved in the first quarter of 2019 to allow continuedramp-up of theA-2 well. Drilling commenced on the ST 320A-3 well during the fourth quarter 2018 and is forecasted to reach target intervals in the first quarter of 2019. We believe the stratigraphic information from a high quality thick Miocene sand that was penetrated in an offset well reduced the risk on the ST 320A-3 prospect. W&T has a 10.8% interest in the ST 320A-3 well until certain performance thresholds are met.

Viosca Knoll 823 “Virgo” (operated, deepwater, in JV Drilling Program):The Virgo field platform rig drilled theA-13 well to target depth and found 77 feet of net vertical pay in the 2.4 Sec and 3.4 Sec sand intervals. Production from this well is expected to commence in the first quarter of 2019 once the current dual completion operation has been finished. W&T plans to demobilize the Nabors MODS 201 rig from Virgo upon completion of theA-13 well.

Well Recompletions and Workovers:During the fourth quarter of 2018, the Company performed three recompletions that added approximately 1,300 Boe per day of initial production and five workovers that added approximately 2,175 Boe per day of initial production.

Year-End 2018 Proved Reserves

The Company’syear-end 2018 SEC proved reserves increased 13% to 84.0 MMBoe, with 58% comprised of liquids (46% crude oil and 12% NGLs) and 42% natural gas, from 74.2 MMBoe atyear-end 2017. The Company achieved a proved reserve replacement rate (including revisions, acquisitions and dispositions) of 174% for calendar year 2018. At year end, approximately 64% of 2018 proved reserves were classified as proved developed producing, 16% as proved developednon-producing and 20% as proved undeveloped.

Total production in 2018 of approximately 13.3 MMBoe was more than offset by 18.8 MMBoe of upward revisions to previous reserve estimates due to better-than-expected well performance in several key fields, as well as 2.1 MMBoe of new extensions and discoveries. W&T also had favorable revisions of 2.3 MMBoe due to price increases of $14.22 per barrel in crude and an increase of $0.12 per Mcf in natural gas.

8

The present value of W&T’s reported SEC proved reserves, discounted at 10%(“PV-10”), atyear-end 2018 was $1,439.8 million, up 45% from $992.9 million at the end of 2017. The 2018 SECPV-10 is based on an average crude oil price of $65.56 per barrel and an average natural gas price of $3.10 per Mcf, both after adjustment for quality, transportation, fees, energy content, and regional price differentials. For 2017, the SECPV-10 was based on an average crude oil price of $51.34 per barrel and an average natural gas price of $2.98 per Mcf.

(1) PV-10 for this presentation excludes any provision for asset retirement obligations or income taxes.

In accordance with guidelines established by the SEC, our estimated proved reserves as of December 31, 2018 were determined to be economically producible under existing economic conditions, which requires the use of the12-month average commodity price for each product, calculated as the unweighted arithmetic average of the price on the first day of each month for the year end December 31, 2018. The West Texas Intermediate spot price and the Henry Hub spot price were utilized as the referenced price and after adjusting for quality, transportation, fees, energy content and regional price differentials. In determining the estimated realized price for NGLs, a ratio was computed for each field of the NGLs realized price compared to the crude oil realized price. Then, this ratio was applied to the crude oil price using SEC guidance. Such prices were held constant throughout the estimated lives of the reserves. Future production and development costs are based onyear-end costs with no escalations.

Standardized measure of future net cash flows of our SEC proved reserves was (i) $1,067 million at December 31, 2018, which includes reductions associated withPV-10 $179 million of discounted asset retirement obligations and $194 million of discounted future income taxes and (ii) $741 million at December 31, 2017, which includes reductions associated withPV-10 $192 million of discounted asset retirement obligations and $274 million for discounted future income taxes.

Non-GAAP Information

Certain financial information included in our financial results are not measures of financial performance recognized by accounting principles generally accepted in the United States, or GAAP. Thesenon-GAAP financial measures are “Adjusted Net Income,” “EBITDA” and “Adjusted EBITDA.” Our management uses thesenon-GAAP financial measures in its analysis of our performance. These disclosures may not be viewed as a substitute for results determined in accordance with GAAP and are not necessarily comparable tonon-GAAP performance measures which may be reported by other companies.

Reconciliation of Net Income to Adjusted Net Income

“Adjusted Net Income” does not include the unrealized commodity derivative (gain) loss, bad debt reserve, gain on debt transactions, lawsuits and settlements, penalties, litigation and related interest and associated income tax adjustments. Adjusted Net Income is presented because the timing and amount of these items cannot be reasonably estimated and affect the comparability of operating results from period to period, and current periods to prior periods.

Reconciliation of Net Income to Adjusted EBITDA

We define EBITDA as net income plus income tax expense (benefit), net interest expense, and depreciation, depletion, amortization and accretion. Adjusted EBITDA excludes the unrealized commodity derivative (gain) loss, bad debt reserve, gain on debt transactions, lawsuits and settlements, and civil penalties and other litigation. We believe the presentation of EBITDA and Adjusted EBITDA provides useful information regarding our ability to service debt and to fund capital expenditures. We believe this presentation is relevant and useful because it helps our investors understand our operating performance and makes it easier to compare our results with those of other companies that have different financing, capital and tax structures. EBITDA and 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. EBITDA and Adjusted EBITDA, as we calculate them, may not be comparable to EBITDA and Adjusted EBITDA measures reported by other companies. In addition, EBITDA and Adjusted EBITDA do not represent funds available for discretionary use. Adjusted EBITDA margin represents the ratio of Adjusted EBITDA to total revenues.

The following table presents a reconciliation of our net income to EBITDA and Adjusted EBITDA along with our Adjusted

EBITDA margin.
