President and Chief Executive Officer Timothy S. Duncan commented: “2018 was a transformative year for the company, as we combined the best aspects of two companies, following our merger with Stone Energy. The benefits of the combination have shown results immediately, as we are a stronger, free cash flow positive company with ample liquidity and a significant inventory of drilling locations in both the US Gulf of Mexico and offshore Mexico. Our strategy of executing asset management and drilling projects around existing infrastructure in the US Gulf of Mexico complements our high impact exploration and development projects in offshore Mexico.”

“In the last twelve months we have seen our proved developed reserves increase 20%, as compared to the pro forma reserves at December 31, 2017. We have also added three smallbolt-on transactions at a low entry cost, including the Gunflint acquisition in January of 2019. We have increased our liquidity position and continued to improve our already robust leverage metrics. We have alsore-affirmed the potential of our globally recognized Zama discovery through our ongoing appraisal program.”

“Our average daily production in 2018 on a pro forma basis was 52.4 MBoe/d, which was on the high end of our pro forma guidance range of 49.0 – 53.0 MBoe/d, allowing us to generate $585 million of pro forma Adjusted EBITDA for the full year 2018, inclusive of hedges, and a pro forma capital program of $452 million, inclusive of plugging and abandoning activities (“P&A”). Although the merger with Stone required us to spend more capital in 2018 on P&A andnon-recurring repairs and maintenance than we normally would have, in 2019 those costs are expected to go down materially.”

“In the US Gulf of Mexico, we executed a series of deepwater subseatie-back projects in 2018 and early 2019, namely the Mt. Providence well, which was connected to our Pompano facility, and the Tornado 3 and Boris 3 wells, that will flow back to the Helix Producer 1(“HP-1”) in our operated Phoenix complex once the wells are completed. TheHP-1dry-dock project in the first quarter of 2019 was flawlessly executed by the Talos team and our partner Helix Energy Solutions, and we expect the production in the Phoenix complex to be restarted in the coming days. Soon thereafter we expect to bring the impactful Tornado 3 and Boris 3 wells online, which will put Talos in a position to grow production year over year while continuing to generate free cash flow in the current price environment for 2019. In shallow water, our asset management and drilling activities have allowed assets such as Ewing Bank 305/306 to achieve production levels not seen in the last 15 years.”

“We also continue to be active and to execute on our business development and commercial activities. In addition to the aforementionedbolt-on acquisitions, we have acquired the Antrim stranded discovery from ExxonMobil and have entered into partnerships to drill two deepwater projects in 2019, the Bulleit and Orlov prospects.”

“In Mexico on the Zama project, our operations execution has been outstanding. As part of the ongoing appraisal program we confirmed theoil-water contact per our geological model and have encountered more sand than expected in the firstdown-dip location. We are excited about the impact this discovery will have in the Mexican economy and to Talos shareholders. Also in offshore Mexico, we will start to execute on the inventory we acquired as part of the cross-assignment of interest between Block 2 and Block 31, which includes thelow-risk but high impact Olmeca project on Block 31.”

“In conclusion, we are very happy with our 2018 results, but we are already looking forward to 2019 and beyond. We will continue to relentlessly execute on our operations and strategy of responsibly growing production at an appropriate pace that allows for the continued generation of positive free cash flow while diligently pursuing additional business development opportunities that fit our asset footprint and core competencies. We believe this is only the beginning of the Talos journey.”

RECENT DEVELOPMENTS AND OPERATIONS UPDATE

Drilling and Exploration Activities

Deepwater

•

Helix Producer 1dry-dock: theHP-1 departed the shipyard on March 7, 2019. After a period of sea trials, Talos expects production from the Phoenix complex tore-start on or about March 20, 2019, resulting in a totalshut-in period of 56 days. The production impact of theshut-in in the Phoenix complex in the first quarter of 2019 is estimated to be between 9.0 – 13.0 MBoe/d, whereas the annualized impact for full year 2019 production is estimated to be between 2.0 – 3.0 MBoe/d. This impact is already accounted for in our annual guidance, as theshut-in in the Phoenix complex was a known, expected event.

•

The Tornado 3 well was drilled in December, 2018 and is scheduled to begin completions operations in late March, with an expected duration of 21 days. The well is anticipated to commence production by early second quarter 2019, with an expected gross production rate between 10.0 MBoe/d – 15.0 MBoe/d, or 5.0 MBoe/d – 7.5 MBoe/d net to Talos after royalties. Talos is the operator and owns a 65% working interest, with Kosmos Energy owning the remaining 35% working interest.

•

The Boris 3 well was spud in January 2019 and was drilled to a total depth of approximately 15,000 feet and logged approximately 75 feet gross and 56 feet net of true vertical pay, 360 feetup-dip of 27 MMBoe of historical production in theB-4 Sand. Boris 3 is scheduled to begin completion operations inmid-April with an expected duration of 21 days and is expected to initiate production in the second quarter of 2019. Talos expects Boris 3 to have initial production between 3.0 – 5.0 MBoe/d gross, or 2.8 – 4.6 MBoe/d net to Talos after royalties. Talos is the operator and owns 100% working interest in all Boris wells.

•

Bulleit prospect: Talos has signed a participation agreement with a subsidiary of EnVen Corporation to drill the Green Canyon 21 Bulleit prospect. Talos will be the operator and has an initial working interest of 66.7% in the lease. Bulleit is an amplitude-supported Pliocene prospect with similar seismic attributes to the analogous sand section in Talos’s Green Canyon 18 field, which has produced approximately 39 MMBoe to date. Talos expects to spud the well in the second quarter of 2019. If successful, the well would be completed and tied back to the Talos owned and operated Green Canyon 18 (“GC 18”) facility approximately 10 miles away. Talos anticipates first production within12-18 months from spud date and estimates that Bulleit has the potential to deliver initial production between 8.0 MBoe/d – 15.0 MBoe/d gross on an unrisked basis.

•

Orlov prospect: Talos has signed a participation agreement to engage in the drilling of the Green Canyon 200 Orlov prospect. Fieldwood Energy will be the operator and Talos has a working interest of 30% in the prospect. Orlov is an amplitude-supported Miocene prospect with similar geophysical and structural attributes to the Talos operated Boris field, which has produced approximately 27 MMBoe to date. Talos expects the well to spud near the end of the first quarter of 2019. If successful, the well would be completed and tied-back to the Fieldwood operated Green Canyon 158 Bullwinkle facility. Talos anticipates first production within12-18 months from spud date and estimates that Orlov has the potential to deliver between 8.0 MBoe/d – 15.0 MBoe/d gross on an unrisked basis

Mexico

Block 7 – Zama appraisal program

As previously announced, theZama-2 appraisal penetration was successfully and safely completed approximately 28 days ahead of schedule and 25% below projected costs. The well confirmed a contiguous Zama Upper Miocene sandstone interval thicker than theZama-1 discovery well and slightly thicker than thepre-drill estimates for theZama-2 well, with high quality rock properties analogous to Upper Miocene sands in the US Gulf of Mexico.

TheZama-2 penetration also reached theoil-water contact slightly deeper than the anticipated depth and consistent with our geophysical models. Preliminary pressure data indicates that the reservoir area around theZama-2 appraisal well is connected to theZama-1 discovery well and Talos expects theZama-2 vertical sidetrack and theZama-3 wells will provide additional information about the reservoir connectivity and consistency.

The next step of the appraisal program is currently underway with anup-dip vertical penetration in the Zama reservoir from the main bore hole of theZama-2 well, called the Zama2-ST, which has been cored and a drill stem test will be performed in the coming weeks. The second appraisal well,Zama-3, will be drilled to the south of the original discovery well and will help delineate the reservoir continuity and quality in the southern part of the field and will be cored to better understand the reservoir geology.

Block 2 and Block 31 Exploration program

Talos and its partners expect to drill two exploration wells in Block 2 and two delineation wells in Block 31 in 2019.

•

In Block 2, the well to test the Acan prospect is expected to spud in the second quarter of 2019.

•

In Block 31, theOlmeca-1 well is expected to be drilled in the second half of 2019. The Olmeca complex has been significantlyde-risked by theXaxamani-1 well drilled by Pemex in 2003. The 2019 drilling campaign will be to appraise the same geological structure initially tested by Pemex and, if successful, a final investment decision to develop these assets could be reached in 2020.

Business Development Activities

Acquisition of the Antrim Discovery from ExxonMobil

On January 23, 2019, Talos and ExxonMobil (“Exxon”) executed an Acquisition Agreement through which Talos acquired 100% interest in the Antrim Project in Green Canyon Block 364 (“GC 364”).

Exxon drilled an exploratory well in GC 364 in November 2017 that encountered hydrocarbons in asub-salt Miocene reservoir and subsequently divested of the discovery well and the GC 364 lease to Talos for further appraisal and a possible development.

Talos plans to drill an additional well to further appraise the discovered resource. The Company is still developing a detailed timeline for the appraisal and development plan over the next few years with significant time ahead of the June 2025 lease expiration. If the appraisal is successful, Talos is currently considering atie-back to the Talos owned and operated GC 18 facility acquired from Whistler in 2018.

In addition to a nominal upfront cash consideration payment by Talos, Exxon will receive an overriding royalty interest in the lease as well as a future cash payment upon the earlier of 30 days following the completion of drilling operations on the first well or by the end of the third quarter of 2020.

Gunflint Acquisition

On January 11, 2019, Talos acquired an approximate 9.6%non-operated working interest in the Gunflint producing asset for $29.6 million from Samson Offshore Mapleleaf, LLC. Gunflint is located in the Company’s Mississippi Canyon core area. The asset’s average production for October and November of 2018 was approximately 1.5 - 1.8 MBoe/d and as of November 30, 2018, had proved reserves of 2.2 MMBoe (approximately 80% proved developed) - both production and reserves are net to the Company’s acquired interest, which are not included in ouryear-end reserves.

PROVED RESERVES – AS OF DECEMBER 31, 2018

As of December 31, 2018, Talos had proved reserves of 151.7 MMBoe, with 81% comprised of liquids (74% crude oil and 7% NGLs). As compared to the pro formayear-end 2017 reserves, the Company achieved 100% reserve replacement rate. Talos accomplished this replacement rate in a year that the drilling program was mainly designed to convert proved undeveloped reserves into proved developed reserves while integrating the Stone merger. As such, proved developed reserves increased approximately 20% year over year, and is not inclusive of the recently successful Boris 3 well in the Phoenix complex, which is still classified as proved undeveloped in theyear-end reserves. The recently announced Gunflint transaction is also not included in the year end reserves.

The discovered resources associated with the Company’s offshore Mexico assets are not yet qualified as proved reserves per Securities and Exchange Commission (the “SEC”) rules and, therefore, are not included in any of the information provided in this press release.

The standardized measure of proved reserves and the present value of the Company’s proved reserves, discounted at 10%(“PV-10”)⁽¹⁾, atyear-end 2018 were $3.3 billion and $3.9 billion, respectively. Standardized measure andPV-10include the present value of all asset retirement obligations associated with the relevant assets and properties.

In accordance with guidelines established by the SEC, the Company’s 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 price for each commodity, 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 appropriately adjusted for quality, transportation, fees, energy content and basis differentials. Therefore, the standardized measure andPV-10 of Talos’s proved reserves at December 31, 2018, are based on an average crude oil price of $65.56 per barrel and an average natural gas price of $3.10 per MMBtu, prior to being adjusted for quality, transportation, fees, energy content and basis differentials. The average adjusted product prices used in determining standardized measure andPV-10 are $69.42 per barrel of oil, $29.50 per barrel of NGL, and $3.08 per Mcf of gas.

FOURTH QUARTER 2018 RESULTS

Production, Realized Prices and Revenue

Production: Production for the fourth quarter of 2018 was 4.9 million Boe and was comprised of 3.6 million barrels of oil, 0.3 million barrels of NGLs and 6.2 billion cubic feet (“Bcf”) of natural gas. Oil and NGLs production accounted for 79% of the total production for the fourth quarter of 2018.

During the quarter, Talos evacuatednon-essential personnel andshut-in production on certain Gulf of Mexico assets as a result of Hurricane Michael, which negatively impacted production. Talos suffered no damage to its assets. In addition to Hurricane Michael, production was negatively affected by several minor third-party downtime events.

Although a certain level of third party downtime is expected and planned for, these interruptions in production were limited to the fourth quarter and are not expected to have a material impact going forward.

The table below provides additional detail of the Company’s oil, natural gas and NGLs production volumes and sales prices per unit for the three months and year ended December 31, 2018:

The pro forma capital expenditures for 2018 were $452.4 million, inclusive of Plugging & Abandonment costs. Pro forma capital expenditures for the year excludes $29.8 million of accrued, but unpaid change of control costs for the seismic data acquired in connection with the Stone Combination. As part of the negotiation between the parties, these costs will be paid in 2019, 2020 and 2021 in equal installments. It also excludesnon-cash equity based compensation and $9.0 million of corporate office renovation costs, which were reimbursed by the property manager, thus resulting in a zero cash impact to Talos.

The table below provides additional detail of the Company’s capital expenditures:

CAUTIONARY STATEMENT ABOUT FORWARD-LOOKING STATEMENTS

This communication may contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical fact included in this communication, regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this communication, the words “could,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on our current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events.

We caution you that these forward-looking statements are subject to numerous risks and uncertainties, most of which are difficult to predict and many of which are beyond our control. These risks include, but are not limited to, commodity price volatility, inflation, lack of availability of drilling and production equipment and services, environmental risks, drilling and other operating risks, regulatory changes, the uncertainty inherent in estimating reserves and in projecting future rates of production, cash flow and access to capital, the timing of development expenditures, potential adverse reactions or changes to competitive responses to the business combination between Talos Energy LLC and Stone Energy Corporation, the possibility that the anticipated benefits of such business combination are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies, and other factors that may affect our future results and business, generally, including those discussed under the heading “Risk Factors” in our Quarterly Report on Form10-Q for the quarter ended September 30, 2018, filed with the SEC on November 5, 2018, and in our Annual Report on Form10-K for the year ended December 31, 2018, to be filed with the SEC subsequent to the issuance of this communication.

Estimates for our future production volumes are based on assumptions of capital expenditure levels and the assumption that market demand and prices for oil and gas will continue at levels that allow for economic production of these products. The production, transportation and marketing of oil and gas are subject to disruption due to transportation and processing availability, mechanical failure, human error, hurricanes and numerous other factors. Our estimates are based on certain other assumptions, such as well performance, which may vary significantly from those assumed. Therefore, we can give no assurance that our future production volumes will be as estimated.

Proved reserves attributable to the Gunflint assets as of November 30, 2018 were estimated by Talos Energy Inc.’s internal reserve engineer based upon information furnished by Samson Offshore Mapleleaf, LLC, as seller, but have not been audited or prepared by any third-party independent petroleum engineer.

SUPPLEMENTALNON-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, Adjusted Earnings Per Share, Adjusted EBITDA”, “Adjusted EBITDA excluding hedges”, “Adjusted EBITDA Margin”, “Adjusted EBITDA Margin Excluding Hedges”, “Net Debt”, “Annualized Adjusted EBITDA”, “Net Debt to Annualized Adjusted EBITDA” and“PV-10.” These disclosures may not be viewed as a substitute for results determined in accordance with GAAP and are not necessarily comparable tonon-GAAP measures which may be reported by other companies.

Reconciliation of Net Income (Loss) to Adjusted EBITDA; reconciliation of Adjusted EBITDA margin

“Adjusted EBITDA” is not a measure of net income (loss) as determined by GAAP. We use this measure as a supplemental measure because we believe it provides meaningful information to our investors. We define Adjusted EBITDA as net income (loss) plus interest expense, income tax expense, depreciation, depletion and amortization, accretion expense, loss on debt extinguishment, transaction related costs, the net change in the fair value of derivatives (mark to market effect, net of cash settlements and premiums related to these derivatives),non-cash (gain) loss on sale of assets,non-cash write-down of oil and natural gas properties,non-cash write-down of other well equipment inventory andnon-cash equity based compensation expense. We believe the presentation of Adjusted EBITDA is important to provide management and investors with (i) additional information to evaluate, with certain adjustments, items required or permitted in calculating covenant compliance under our debt agreements, (ii) important supplemental indicators of the operational performance of our business, (iii) additional criteria for evaluating our performance relative to our peers and (iv) supplemental information to investors about certain materialnon-cash and/or other items that may not continue at the same level in the future. Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP or as an alternative to net income (loss), operating income (loss) or any other measure of financial performance presented in accordance with GAAP.

“Adjusted EBITDA excluding hedges” is defined as Adjusted EBITDA plus net cash receipts (payments) on settled derivative instruments. We believe the presentation of Adjusted EBITDA excluding hedges is important to provide management and investors with information about the impact of actual commodity price changes on our business.

“Adjusted EBITDA Margin” is defined as Adjusted EBITDA divided by Revenue, as a percentage. It is also defined as Adjusted EBITDA divided by the total production volume, expressed in Boe, in the period, and described as dollar per Boe. We believe the presentation of Adjusted EBITDA Margin is important to provide management and investors with information about how much we retain in Adjusted EBITDA terms as compared to the revenue we generate and how much per barrel we generate after accounting for certain operational and corporate costs.

“Adjusted EBITDA margin excluding hedges” bears the same definition and our intended utility of Adjusted EBITDA margin, but using Adjusted EBITDA excluding hedges instead of Adjusted EBITDA.

The following table presents a reconciliation of the GAAP financial measure of net income (loss) to Adjusted EBITDA, from Adjusted EBITDA to Adjusted EBITDA excluding hedges, Adjusted EBITDA margins and Adjusted EBITDA margins excluding hedges for each of the periods indicated (in thousands, except for Boe, $/Boe and percentage data):

(1)

The adjustments for the derivative fair value (gain) loss and net cash receipts (payments) on settled derivative instruments have the effect of adjusting net income (loss) for changes in the fair value of derivative instruments, which are recognized at the end of each accounting period because we do not designate commodity derivative instruments as accounting hedges. This results in reflecting commodity derivative gains and losses within Adjusted EBITDA on a cash basis during the period the derivatives settled.

(2)	One Boe is equal to six Mcf of natural gas or one Bbl of oil or NGLs based on an approximate energy equivalency. This is an energy content correlation and does not reflect a value or price relationship between the commodities.

Reconciliation of Adjusted Net Income and Adjusted Earnings per Share

“Adjusted Net Income” is not a measure of net income (loss) as determined by GAAP. We use this measure as a supplemental measure because we believe it provides meaningful information to our investors. We define Adjusted Net Income as net income (loss) plus accretion expense, loss on debt extinguishment, transaction related costs, the net change in the fair value of derivatives (mark to market effect, net of cash settlements and premiums related to these derivatives) andnon-cash equity based compensation expense. We believe the presentation of Adjusted Net Income is important to provide management and investors with (i) important supplemental indicators of the operational performance of our business, (ii) additional criteria for evaluating our performance relative to our peers and (iii) supplemental information to investors about certain materialnon-cash and/or other items that may not continue at the same level in the future. Adjusted Net Income has limitations as an analytical tool and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP or as an alternative to net income (loss), operating income (loss) or any other measure of financial performance presented in accordance with GAAP.

“Adjusted Earnings per Share” is defined as Adjusted Net Income divided by the number of common shares.

Reconciliation of Net Debt and Net Debt to Annualized Adjusted EBITDA

“Net Debt” is not a measure of Debt as determined by GAAP. We define Net Debt as the total Debt principal of the Company plus the Capital Lease balance minus Cash.

“Net Debt to Annualized Adjusted EBITDA” is defined as Net Debt divided by the Annualized Adjusted EBITDA.

We believe the presentation of Net Debt, Annualized Adjusted EBITDA and Net Debt to Annualized Adjusted EBITDA is important to provide management and investors with additional important information to evaluate our business. These measures are widely used by investors and ratings agencies in the valuation, comparison, rating and investment recommendations of companies.

Reconciliation of Net Debt to Adjusted EBITDA
Net Debt / Annualized Adjusted EBITDA		1.0x

The Annualized Adjusted EBITDA information included in this communication provides additional relevant information to our investors and creditors. Talos needs to comply with a financial covenant included in its Bank Credit Facility that requires it to maintain a Net Debt to Annualized Adjusted EBITDA ratio equal to or lower than 3.0x. For purposes of covenant compliance, Annualized Adjusted EBITDA, with certain adjustments, is calculated the following way:

•

On December 31, 2018: two times the Adjusted EBITDA for the six month period ended on December 31, 2018

•

On March 31, 2019: Adjusted EBITDA for the nine month period ended on March 31 divided by nine and multiplied by 12

•

On June 30, 2019: Adjusted EBITDA for the 12 month period ended on June 30, 2019

•

For every subsequent quarter: trailing 12 month Adjusted EBITDA

Reconciliation ofPV-10 to Standardized Measure

“PV-10” is anon-GAAP financial measure and differs from the standardized measure of discounted future net cash flows, which is the most directly comparable GAAP financialmeasure. PV-10 is a computation of the standardized measure of discounted future net cash flows on apre-tax basis.PV-10 is equal to the standardized measure of discounted future net cash flows at the applicable date, before deducting future income taxes, discounted at 10 percent. We believe that the presentation ofPV-10 is relevant and useful to investors because it presents the discounted future net cash flows attributable to our estimated net proved reserves prior to taking into account future corporate income taxes, and it is a useful measure for evaluating the relative monetary significance of our oil and natural gas properties. Further, investors may utilize the measure as a basis for comparison of the relative size and value of our reserves to other companies without regard to the specific tax characteristics of such entities. We use this measure when assessing the potential return on investment related to our oil and natural gas properties.PV-10, however, is not a substitute for the standardized measure of discounted future net cash flows. OurPV-10 measure and the standardized measure of discounted future net cash flows do not purport to represent the fair value of our oil and natural gas reserves.

The following table provides a reconciliation ofPV-10 of our proved reserves to the standardized measure of discounted future net cash flows at December 31, 2018:


	December 31, 2018
Standardized measure	$	3,340,246
Plus: present value of future income taxes discounted at 10%		585,017

PV-10		3,925,263
