CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

The information contained in, or incorporated by reference into, this prospectus include “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 Exchange Act. All statements, other than statements of historical fact included in this prospectus and the documents incorporated by reference herein, 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 prospectus and the documents incorporated by reference herein, the words “could,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project,” “forecast,” “may,” “objective,” “plan” 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. These forward-looking statements are based on management’s current belief, based on currently available information, as to the outcome and timing of future events. Forward-looking statements may include statements about:

• business strategy;

• reserves;

• exploration and development drilling prospects, inventories, projects and programs;

• our ability to replace the reserves that we produce through drilling and property acquisitions;

• financial strategy, liquidity and capital required for our development program and other capital expenditures;

• realized oil and natural gas prices;

• timing and amount of future production of oil, natural gas and natural gas liquids (“NGLs”);

• our hedging strategy and results;

• future drilling plans;

• availability of pipeline connections on economic terms;

• competition, government regulations and political developments;

• our ability to obtain permits and governmental approvals, including with respect to repairs to the Ram Powell facility;

• pending legal, governmental or environmental matters;

• our marketing of oil, natural gas and NGLs;

• leasehold or business acquisitions on desired terms;

• costs of developing properties;

• general economic conditions;

• credit markets;

• impact of new accounting pronouncements on earnings in future periods;

• estimates of future income taxes;

• our estimates and forecasts of the timing, number, profitability and other results of wells we expect to drill and other exploration activities;

• uncertainty regarding our future operating results and our future revenues and expenses; and

• plans, objectives, expectations and intentions contained in this prospectus that are not historical.

3

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, including the sharp decline in oil prices beginning in March 2020, the impact of the coronavirus disease 2019 and governmental measures related thereto on global demand for oil and natural gas and on the operations of our business; the ability or willingness of the Organization of Petroleum Exporting Countries (“OPEC”) and non-OPEC countries, such as Saudi Arabia and Russia, to set and maintain oil production levels; the impact of any such actions, lack of transportation and storage capacity as a result of oversupply, government regulations and actions or other factors; inflation; lack of availability of drilling and production equipment and services; environmental risks; failure to find, acquire or gain access to other discoveries and prospects or to successfully develop and produce from our current discoveries and prospects; geologic risk; drilling and other operating risks; well control risk; 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 competitive responses to our acquisitions and other transactions; the possibility that the anticipated benefits of our business combinations are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of acquired assets and operations; and the other risks discussed under the heading “Risk Factors” in this prospectus, our most recent Annual Report on Form 10-K, any subsequently filed Quarterly Reports on Form 10-Q and any subsequently filed Current Reports on Form 8-K, all of which are incorporated by reference into this prospectus, and any risk factors included in any applicable prospectus supplement.

Reserve engineering is a process of estimating underground accumulations of oil, natural gas and NGLs that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by reserve engineers. In addition, the results of drilling, testing and production activities may justify upward or downward revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ significantly from the quantities of oil, natural gas and NGLs that are ultimately recovered.

Should one or more of the risks or uncertainties described in this prospectus or the documents incorporated by reference herein occur, or should underlying assumptions prove incorrect, our actual results and plans could differ materially from those expressed in any forward-looking statements. All forward-looking statements, expressed or implied, included in this prospectus and the documents incorporated by reference herein are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue. All forward-looking statements speak only as of the date of this prospectus and the documents incorporated by reference herein. Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this prospectus or the documents incorporated by reference herein.

ABOUT TALOS ENERGY INC.

Overview

We are a technically driven independent exploration and production company focused on safely and efficiently maximizing value through our operations, currently in the United States Gulf of Mexico and offshore Mexico. We leverage decades of geology, geophysics and offshore operations expertise towards the acquisition, exploration, exploitation and development of assets in key geological trends that are present in many offshore basins around the world.

We have historically focused our operations in the Gulf of Mexico because of our deep experience and technical expertise in the basin, which maintains favorable geologic and economic conditions, including multiple reservoir formations, comprehensive geologic and geophysical databases, extensive infrastructure and an attractive and robust asset acquisition market. Additionally, we have access to state-of-the-art three-dimensional seismic data, some of which is aided by new and enhanced reprocessing techniques that have not been previously applied to our current acreage position. We use our broad regional seismic database and our reprocessing efforts to generate a large and expanding inventory of high-quality prospects, which we believe greatly improves our development and exploration success. The application of our extensive seismic database, coupled with our ability to effectively reprocess this seismic data, allows us to both optimize our organic drilling program and better evaluate a wide range of business development opportunities, including acquisitions and joint venture opportunities, among others.

In order to determine the most attractive returns for our drilling program, we employ a disciplined portfolio management approach to stochastically evaluate all of our drilling prospects, whether they are generated organically from our existing acreage, an acquisition or joint venture opportunities. We add to and reevaluate our inventory in order to deploy capital as efficiently as possible.

Unless otherwise indicated or the context otherwise requires, references in this prospectus to “us,” “we,” “our” or the “Company” are to Talos Energy Inc. and its wholly-owned subsidiaries.

Our Corporate Information

Our principal executive offices are located at 333 Clay Street, Suite 3300, Houston, Texas 77002, and our telephone number at that address is (713) 328-3000. Our website address is www.talosenergy.com. Information contained on our website does not constitute a part of this prospectus.

RISK FACTORS

You should carefully consider the risk factors included in our most recent Annual Report on Form 10-K, any subsequently filed Quarterly Reports on Form 10-Q and any subsequently filed Current Reports on Form 8-K as incorporated herein by reference, as well as the other information contained, or incorporated by reference, in this prospectus, before deciding to invest in our common stock. Any of these risks could materially and adversely affect our business, prospects, results of operations, financial condition and/or cash flows. In addition, these risks are not the only risks that we face. Additional risks and uncertainties not currently known to us or those that we currently view to be immaterial could also materially and adversely affect our business, prospects, results of operations, financial condition and/or cash flows. In any such case, you may lose all or a part of your investment in our common stock. Please read the section entitled “Cautionary Note Regarding Forward Looking Statements.”

USE OF PROCEEDS

We will not receive any of the proceeds from the sale of our common stock being offered by the selling stockholder. We are required to pay certain offering fees and expenses in connection with the registration of the selling stockholder’s shares and to indemnify the selling stockholder against certain liabilities.

SELLING STOCKHOLDER

This prospectus relates to the offer and sale from time to time of up to 4,602,460 shares of our common stock by the stockholder identified in the table below, who we refer to in this prospectus as the “selling stockholder” and its transferees, pledgees, donees, assignees or other successors (each also a selling stockholder for purposes of this prospectus). The selling stockholder identified below may currently hold or acquire at any time shares of our common stock in addition to those registered hereby.

We are registering these 4,602,460 shares of our common stock for sale by the selling stockholder named below pursuant to the Castex Registration Rights Agreement, which we entered into in connection with the closing of the Castex Acquisition. For additional information regarding the Castex Registration Rights Agreement, see “Description of Capital Stock—Castex Registration Rights Agreement.”

Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to such securities. Except as otherwise indicated, all persons listed below have sole voting and investment power with respect to the shares of our common stock beneficially owned by them. The mailing address of the listed beneficial owner is 333 Clay Street, Suite 2900, Houston, Texas 77002.

The information in the table below (other than the percentages of our outstanding common stock beneficially owned) in respect of the selling stockholder was furnished by or on behalf of the selling stockholder and is as of the date hereof. Except as may be noted elsewhere in this prospectus relating to the Castex Purchase Agreement and the Castex Registration Rights Agreement, the selling stockholder does not have, and within the past three years has not had, any material relationship with us or any of our affiliates.

Information concerning the selling stockholder may change from time to time and any changed information will be set forth in supplements to this prospectus, if and when necessary. No offer or sale under this prospectus may be made by a stockholder unless that holder is listed in the table below, in any supplement to this prospectus or in an amendment to the related Registration Statement that has become effective. We will supplement or amend this prospectus if applicable to include additional selling stockholders upon provision of all required information to us and subject to the terms of any relevant agreement between us and the selling stockholders.

The selling stockholder is not obligated to sell any of the shares of our common stock offered by this prospectus. Because the selling stockholder identified in the table below may sell some or all of the shares of our common stock owned by them that are included in this prospectus, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of such shares of our common stock, no estimate can be given as to the number of shares of our common stock covered by this prospectus that will be held by the selling stockholder upon termination of this offering. In addition, subject to the Castex Registration Rights Agreement, the selling stockholder may sell, transfer or otherwise dispose of, at any time and from time to time, shares of our common stock they hold in transactions exempt from the registration requirements of the Securities Act after the date on which the selling stockholder provided the information set forth on the table below. Therefore, for purposes of the following table we have assumed that the selling stockholder will sell all of the shares of our common stock beneficially owned by them that are covered by this prospectus, but will not sell any other shares of our common stock that they may currently own.

(2) Castex Energy and Castex Offshore collectively were issued 3,776,888 shares of our common stock, or 5.2%, based on 73,021,695 shares outstanding as of September 7, 2020, pursuant to the Castex Purchase Agreement in connection with the closing of the Castex Acquisition on August 5, 2020. An additional 825,572 shares of our common stock (the “Escrowed Shares”) are currently being held by an indemnity escrow agent pursuant to the Escrow Agreement in order to secure Castex Energy’s and Castex Offshore’s indemnification obligations under the Castex Purchase Agreement in connection with the closing of the Castex Acquisition, as further described below. On                     , 2020, Castex Energy and Castex Offshore transferred their 3,776,888 shares of our common stock and the 825,572 Escrowed Shares to Castex 2005 and the Escrow Agreement pertaining to the Escrowed Shares was assigned to Castex 2005. Castex Holdco is the sole managing member of Castex 2005 and has sole voting and dispositive powers over all shares of our common stock held by it. The foregoing information is based on the Schedule 13G filed by Castex Holdco on August 14, 2020.

(3) On August 5, 2020, pursuant to the Castex Purchase Agreement and the Escrow Agreement, the 825,572 Escrowed Shares were issued to an escrow agent to be held in an indemnity escrow account for a period not to exceed 18 months from the closing of the Castex Acquisition. For so long as any Escrowed Shares are subject to the Escrow Agreement, Castex 2005 has the sole right to vote such shares and such shares are considered beneficially owned by Castex 2005 but, without the consent of Talos Third Coast, Castex 2005 may not dispose of or transfer its interests in such shares. Depending on the determination of any potential claims for indemnification and in accordance with the applicable terms of the Castex Purchase Agreement, assuming the release of all of the Escrowed Shares to Castex 2005, 825,572 Escrowed Shares would be released and transferred to Castex 2005.

(4) The selling stockholder acquired the shares of our common stock from Castex Offshore and Castex Energy following the closing of the Castex Acquisition.

Common Stock

Voting Rights. Holders of our common stock are entitled to one vote for each share of our common stock held. Holders of our common stock are not entitled to vote on any amendment to our Amended and Restated Certificate of Incorporation that relates solely to the terms of one or more outstanding series of preferred stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote on such terms pursuant to our Amended and Restated Certificate of Incorporation, or the Delaware General Corporation Law (“DGCL”).

Our Amended and Restated Certificate of Incorporation provides that, subject to the rights of the holders of any series of preferred stock or any resolution providing for the issuance of such series of stock adopted by our board of directors, the number of authorized shares of either our common stock or preferred stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the voting power.

Our Amended and Restated Bylaws provide that, subject to the rights of the holders of any series of preferred stock, each director of our board of directors will be elected by the vote of a majority of the votes cast affirmatively or negatively with respect to that director’s election at any meeting for the election of directors at which a quorum is present; provided that if, on the 10th day before we mail our notice of meeting to the stockholders, the number of nominees exceeds the number of directors to be elected at the meeting, then the directors will be elected by a vote of a plurality of the votes cast. Subject to the terms of the Stockholders’ Agreement, our Amended and Restated Certificate of Incorporation provides that directors (other than directors elected exclusively by the holders of one or more series of preferred stock) may be removed from office only for cause and only by the affirmative vote of our stockholders that together hold at least 66 2/3% of the voting power of our outstanding shares.

Our Amended and Restated Certificate of Incorporation provides for our board or directors to be divided into three classes of directors, with each class as nearly equal in number as possible, serving staggered three year terms, other than directors which may be elected exclusively by holders of preferred stock, if any. This system of electing and removing directors may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more difficult for stockholders to replace a majority of the directors and helps to ensure that there will be continuity and stability of leadership required to navigate a challenging economic environment while resisting the pressure to focus on short-term results at the expense of the Company’s long-term value and success.

Our Amended and Restated Bylaws provide that unless required otherwise by law, our Amended and Restated Certificate of Incorporation or our Amended and Restated Bylaws, any action other than the election of

10

directors that requires stockholder approval must be authorized by a majority of the votes cast affirmatively or negatively by the stockholders entitled to vote at a meeting at which a quorum is present. Our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws provide that the Amended and Restated Bylaws may be adopted, amended, altered, or repealed by the approval of our board of directors, which must include the approval of a majority of our directors then in office; provided, however, our Amended and Restated Bylaws provide that the provisions in our Amended and Restated Bylaws relating to board size, certain board votes to approve certain related party transactions and certain issuances of preferred stock, and the composition and authority of the Audit Committee and the Governance & Nominating Committee may not be amended, altered or repealed (and no provision inconsistent therewith may be adopted) by our board of directors without the approval of either (i) all of the directors then in office or (ii) a majority of the directors then qualifying as Company Independent Directors as set forth in the Stockholders’ Agreement. Our Amended and Restated Bylaws may also be adopted, amended or repealed by the affirmative vote of the stockholders that together hold at least 66 2/3% of our outstanding shares; provided that until the Apollo Funds and the Riverstone Funds, in the aggregate, beneficially own 50% or less of our outstanding shares of our common stock, any such modifications or amendments adopted by our stockholders are approved by the affirmative vote of the stockholders that together hold a majority of our outstanding shares.

Generally, our Amended and Restated Certificate of Incorporation may be amended, modified or repealed if the amendment, modification or repeal is approved by our board of directors and by the affirmative vote of our stockholders that together hold a majority of our outstanding shares. Subject to the foregoing sentence and the rights of the holders of any series of preferred stock, our Amended and Restated Certificate of Incorporation may be amended as provided by the DGCL.

Apollo Funds and Riverstone Funds, by virtue of their ownership of a majority of the voting power of our common stock (but subject to the Stockholders’ Agreement), will be able to approve any matter brought to a vote of our stockholders without the affirmative vote of any other stockholders.

Dividend Rights. Subject to any preferential dividend rights of outstanding preferred stock, our board of directors may, in its discretion, out of funds legally available for the payment of dividends, declare and pay dividends on our common stock.

Liquidation Rights. In the event of any liquidation, dissolution or winding up, whether voluntary or involuntary, after payment or provision for payment of our debts and other liabilities and payment or setting aside for payment of any preferential amount due to the holders of any series of preferred stock, the holders of our common stock will receive ratably any assets remaining to be paid or distributed.

Preemptive Rights. Under our Amended and Restated Certificate of Incorporation, the holders of our common stock do not have preemptive rights. There are no redemption or sinking fund provisions applicable to our common stock.

Preferred Stock

Under our Amended and Restated Certificate of Incorporation, our board of directors has the authority to issue preferred stock in one or more series, and to fix for each series the voting powers, designations, preferences and relative, participating, optional or other rights and the qualifications, limitations or restrictions, as may be stated and expressed in any resolution or resolutions adopted by our board of directors providing for the issuance of such series as may be permitted by the DGCL, including dividend rates, conversion rights, terms of redemption and liquidation preferences and the number of shares constituting each such series, without any further vote or action by our stockholders.

The purpose of authorizing our board of directors to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of

11

preferred stock, while providing flexibility in connection with possible acquisitions, future financings and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from seeking to acquire, a majority of our outstanding voting stock. Additionally, the issuance of preferred stock may restrict dividends on our common stock, dilute the voting power of our common stock or subordinate the liquidation rights of our common stock.

Exclusive Venue

Our Amended and Restated Certificate of Incorporation requires, to the fullest extent permitted by law, that, unless we consent in writing to the selection of an alternative forum, (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers, employees, agents or stockholders (including beneficial owners of stock) to us or our stockholders, (iii) any action asserting a claim against us arising pursuant to any provision of the DGCL, our Amended and Restated Certificate of Incorporation or our Amended and Restated Bylaws or (iv) any action asserting a claim against us governed by the internal affairs doctrine, will have to be brought only in the Court of Chancery in the State of Delaware. Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers. The enforceability of similar exclusive forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that, in connection with one or more actions or proceedings described above, a court could rule that this provision in the Company’s Amended and Restated Certificate of Incorporation is inapplicable or unenforceable.

The choice of forum provisions summarized above are not intended to, and would not, apply to suits brought to enforce any liability or duty created by the Securities Act or the Exchange Act or other claim for which the federal courts have exclusive jurisdiction. To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. Stockholders may be subject to increased costs to bring these claims, and the choice of forum provisions could have the effect of discouraging claims or limiting investors’ ability to bring claims in a judicial forum that they find favorable.

Castex Registration Rights Agreement

In connection with the closing of the Castex Acquisition, on August 5, 2020, we entered into the Castex Registration Rights Agreement with Castex Energy and Castex Offshore, pursuant to which, among other things and subject to certain restrictions, we were required, among other things, to file with the SEC a shelf registration statement on Form S-3 registering for resale the shares of our common stock issued as consideration in connection with the closing of the Castex Acquisition. We are filing this Registration Statement pursuant to our obligations under the Castex Registration Rights Agreement.

Anti-Takeover Effects of Provisions of our Governing Documents

Although the Apollo Funds and the Riverstone Funds own a majority of our capital stock, our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws contain provisions that may delay, defer or discourage another party from acquiring control of us. We expect that these provisions, which are summarized below, will discourage coercive takeover practices or inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors, which we believe may result in an improvement of the terms of any such acquisition in favor of our stockholders. However, our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws also give our board of directors the power to discourage acquisitions that some stockholders may favor.

Board Designees

Pursuant to a Stockholders’ Agreement and our Amended & Restated Bylaws, the board of directors is to consist of ten (10) members, and the Apollo Funds and the Riverstone Funds (each a “Stockholder Group”) will each independently have the right to designate, in connection with any annual or special meeting of our stockholders at which directors will be elected, (i) two (2) persons for nomination by the board of directors for election to the board of directors (each, a “Nominee”) for so long as such Stockholder Group owns at least (A) 15% of our outstanding common stock or (B) 50% of the number of shares of our common stock issued to such Stockholder Group in connection with the previously disclosed business combination between Talos Energy LLC and Stone Energy Corporation that occurred on May 10, 2018 , after appropriate adjustment for any stock split, subdivision, combination or reclassification of any shares (such shares with respect to each Stockholder Group, the “Initial Group Shares,” and collectively, the “Initial Shares”) and (ii) one (1) Nominee for so long as such Stockholder Group owns (A) at least 5% but less than 15% of our outstanding common stock or (B) at least 50% of the number of Initial Group Shares.

Further, the Stockholders’ Agreement also provides that (i) for so long as the Apollo Funds and the Riverstone Funds collectively own at least (A) 50% of our outstanding common stock or (B) 80% of the number of Initial Shares, the Apollo Funds and the Riverstone Funds shall have the collective right to designate two (2) Nominees, one of whom qualifies as an “independent” under the NYSE listing standards (an “Independent Director”) and the other of whom must either be our Chief Executive Officer or also qualify as an Independent Director, and (ii) for so long as the Apollo Funds and the Riverstone Funds collectively own (A) less than 50% of our outstanding common stock but at least 60% of the Initial Shares or (B) less than 80% of the Initial Shares but at least 40% of our outstanding common stock, the Apollo Funds and the Riverstone Funds shall have the collective right to designate one (1) Nominee, whom must either be our Chief Executive Officer or qualify as an Independent Director.

The Apollo Funds and the Riverstone Funds have agreed to vote their shares of our common stock in favor of any Nominees designated by the other Stockholder Group, and in accordance with the terms of the Stockholders’ Agreement with respect to all other Nominees.

These provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control of us or our management.

Authorized but Unissued Shares

Our authorized but unissued shares of common stock and preferred stock are available for future issuance without stockholder approval, subject to any limitations imposed by the listing standards of the NYSE. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved shares of our common stock and preferred stock could make more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Requirements for Advance Notification of Stockholder Meetings, Nominations and Proposals

Our Amended and Restated Bylaws provide that stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of our board of directors, or by a qualified stockholder of record at the time of giving of notice and at the time of the annual meeting, who is entitled to vote at the meeting and who has delivered timely written notice in proper form to our Secretary of the stockholder’s intention to bring such business before the meeting. Our Amended and Restated Bylaws provide that, subject to applicable law, special meetings of the stockholders may be called at any time by (i) the Chairman of our board of directors, (ii) the President, (iii) a majority of our board of directors, (iv) a majority of the executive committee (if any) or (v) the Secretary at the direction of a stockholder, or a group of stockholders, holding at least 25% of our capital stock. Our Amended and Restated Bylaws prohibit the

13

conduct of any business at a special meeting other than as specified in the notice for such meeting. In addition, any stockholder who wishes to bring business before an annual meeting or nominate directors must comply with the advance notice requirements set forth in our Amended and Restated Bylaws and provide us with certain information. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers or changes in control of us or our management.

Action by Written Consent in Lieu of a Meeting

Our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws also provide that, until such time as the Apollo Funds and the Riverstone Funds, in the aggregate, beneficially own 50% or less of our outstanding shares of our common stock, any action that could be taken by stockholders at a meeting of stockholders may be taken without a meeting, without prior notice and without a vote if there is a written consent signed by holders of our outstanding common stock sufficient to take such action if there had been a meeting of stockholders. After such time as the Apollo Funds and the Riverstone Funds, in the aggregate, beneficially own 50% or less of our outstanding shares of common stock, any action that could be taken by stockholders at a meeting of stockholders must be effected at a duly called annual or special meeting and may not be effected by consent in lieu of a stockholder meeting. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control of us or our management.

Related Party Transactions

Our Amended and Restated Bylaws and the Stockholders’ Agreement provide that we will not enter into any related party transaction unless such transaction has been approved by a majority of the disinterested directors or a majority of the Audit Committee. Under the Stockholders’ Agreement, a related party transaction is any transaction or series of related transactions in which we or any of our affiliates is a participant and the Apollo Funds or the Riverstone Funds or any of their respective affiliates or any of our directors has a direct or indirect material interest and the transaction or series of transaction involves payments of $120,000 or more or are otherwise not de minimis in nature. With respect to any related party transaction involving the Apollo Funds or their affiliates, the Audit Committee may request that the Riverstone designees confirm that the Riverstone Funds and their affiliates do not have a material interest in the transaction and, if the Audit Committee makes such a request, the Riverstone designees will not be considered disinterested directors until the Riverstone designees provide such confirmation. With respect to any related party transaction involving the Riverstone Funds or their affiliates, the Audit Committee may request that the Apollo designees confirm that the Apollo Funds and their affiliates do not have a material interest in the transaction and, if the Audit Committee makes such a request, the Apollo designees will not be considered disinterested directors until the Apollo designees provide such confirmation.

Corporate Opportunities and Transactions with Controlling Stockholders

In recognition and anticipation that directors, officers, employees, managing directors or other affiliates of the Apollo Funds and the Riverstone Funds may serve as our directors or officers, that the Apollo Funds and the Riverstone Funds may engage in the same or similar lines of business as we do, and that the Apollo Funds and the Riverstone Funds may have an interest in the same areas of corporate opportunity as we do, our Amended and Restated Certificate of Incorporation provides for the allocation of certain transactions and corporate opportunities between us, on the one hand, and the Apollo Funds and the Riverstone Funds, on the other hand. Specifically, except as otherwise agreed by us and the Apollo Funds and the Riverstone Funds, the Apollo Funds and the Riverstone Funds, and their directors, officers, employees, managing directors or other affiliates who are also directors or officers of us, will be permitted to engage in the same or similar activities or lines of business as we do, to do business with any of our clients, customers, vendors or lessors (or their affiliates), or to make investments in the same kind of property as we do.

We will renounce any interest or expectancy to participate in any business of the Apollo Funds and the Riverstone Funds, and will waive any claim against the Apollo Funds and the Riverstone Funds, or any director,

14

officer, employee, managing director or other affiliate of an Apollo Fund or a Riverstone Fund who is also one of our directors or officers, and will indemnify such entity or person against any claim that such entity or person is liable to us or our stockholders for a breach of any fiduciary duty solely because such entity or person participated in any such business.

In the event that the Apollo Funds and the Riverstone Funds or any director, officer, employee, managing director or other affiliate of the Apollo Funds and the Riverstone Funds, who is also one of our directors or officers acquires knowledge of a potential transaction which may constitute a corporate opportunity for such entity or person and us, such entity or person will not have a duty to offer or communicate information about the corporate opportunity to us. In addition, we will renounce any interest or expectancy in such corporate opportunity and will waive any claim against the Apollo Funds or the Riverstone Funds or any director, officer, employee, managing director or other affiliate of the Apollo Funds or the Riverstone Funds who is also one of our directors or officers and will indemnify such entity or person against any claim that such entity or person is liable to us or our stockholders for breach of any fiduciary duty solely because such entity or person (i) pursues or acquires any corporate opportunity, (ii) directs, recommends, sells, assigns or otherwise transfers the corporate opportunity to another person or (iii) does not communicate the corporate opportunity to us, provided, however, that any corporate opportunity which is expressly offered to a person in writing solely in his or her capacity as one of our officers or directors will belong to us.

The dealers may also be our or the selling stockholder’s customers or may engage in transactions with, or perform services for us or the selling stockholder in the ordinary course of business.

Offers to purchase shares may be solicited directly by the selling stockholder and the sale thereof may be made by the selling stockholder directly to institutional investors or others, who may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale thereof.

The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be named in the applicable prospectus supplement (or a post-effective amendment).

In addition, the selling stockholder may otherwise loan or pledge shares to a financial institution or other third party that in turn may sell the shares short using this prospectus and an applicable prospectus supplement.

LEGAL MATTERS

Vinson & Elkins L.L.P., Houston, Texas, will pass upon certain legal matters relating to the issuance and sale of the shares of our common stock offered hereby on behalf of Talos Energy Inc. Additional legal matters may be passed upon for us, the selling stockholder or any underwriters, dealers or agents by counsel that we may name in any applicable prospectus supplement.

EXPERTS

The consolidated financial statements of Talos Energy Inc., appearing in Talos Energy Inc.’s Annual Report on Form 10-K filed with the SEC on March 12, 2020, for the year ended December 31, 2019, and the effectiveness of Talos Energy Inc.’s internal control over financial reporting as of December 31, 2019, have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their reports thereon included therein, and incorporated herein by reference. Such financial statements are, and audited financial statements to be included in subsequently filed documents will be, incorporated herein in reliance upon the reports of Ernst & Young LLP pertaining to such financial statements and the effectiveness of our internal control over financial reporting as of the respective dates (to the extent covered by consents filed with the SEC) given on the authority of such firm as experts in accounting and auditing.

Prior to the Transactions, Talos Energy was controlled by the Apollo Funds through May 10, 2018. Talos Energy and its historical financial statements were not subject to the SEC and Public Company Accounting Oversight Board (United States) (“PCAOB”) auditor independence rules. The historical financial statements of Talos Energy, the target for purposes of the Transactions, were conducted in accordance with U.S. generally accepted auditing standards and subject to the AICPA independence rules. Upon completion of the Transactions, Talos Energy was deemed the accounting acquirer and as such, its historical 2016 and 2017 financial statements were required to be presented as the predecessor in subsequent SEC filings, audited in accordance with PCAOB audit standards, and subject to SEC auditor independence rules. EY converted its historical audits of Talos Energy to SEC and PCAOB standards.

In November 2016, an Apollo Fund acquired a controlling interest in a company unrelated to Talos Energy (Apollo portfolio company or “APC”) resulting in APC becoming an affiliate of Talos Energy by virtue of being under common control and subject to the SEC and PCAOB auditor independence rules relative to EY’s audits of Talos Energy’s consolidated financial statements conducted in accordance with the PCAOB standards. EY has provided certain non-audit advisory services for APC, including managed services and a tax service that included a contingent fee arrangement. Once APC became an affiliate of Talos Energy in November 2016, the managed services and the contingent fee arrangement provided to APC was inconsistent with the SEC’s and PCAOB’s auditor independence rules relative to EY’s audits of Talos Energy’s consolidated financial statements pursuant to PCAOB standards. The managed services were terminated and the contingent fee arrangement was converted to an appropriate fee arrangement in November 2017. Fees from these engagements from November 2016 to November 2017 were not material to EY or APC. None of the professionals who provided or were involved with the aforementioned engagements were or are a member of the EY audit engagement team with respect to the PCAOB audits of Talos Energy’s consolidated financial statements. The operations and related financial results of APC had no impact on Talos Energy’s operations or its consolidated financial statements. The managed services and contingent fee arrangement were not in any way related to the operations, and did not affect, the consolidated financial statements of Talos Energy. In addition, the results of the managed services and contingent fee arrangement were not subject to audit by EY.

In April 2018, it was determined that a service team in EY France (EY member firm) provided internal audit co-sourcing services during November and December 2017 to an Apollo portfolio company (“APC 2”) controlled by an Apollo Fund and thus an affiliate of Talos Energy by virtue of being under common control. The service ceased in December 2017. Fees from this engagement were not material to EY or APC 2. None of the professionals who provided or were involved with the aforementioned engagement were or are a member of the

18

EY audit engagement team with respect to the PCAOB audits of Talos Energy’s consolidated financial statements. The operations and related financial results of APC 2 had no impact on Talos Energy’s operations or its consolidated financial statements. The co-sourcing services were not in any way related to the operations, and did not affect, the consolidated financial statements of Talos Energy. In addition, the results of the co-sourcing services were not subject to audit by EY.

In 2016, a staff level employee of EY in the United States provided audit services to Talos Energy while holding a de minimis financial relationship with an affiliate of Talos Energy. Additionally, during 2016 and 2017, four employees of EY or an associated firm held financial relationships with certain affiliates of Talos Energy while providing non-audit services to other sister affiliates of Talos Energy. Each of these individuals were deemed to be covered persons pursuant to the SEC and PCAOB independence rules as it pertains to EY’s audits of Talos Energy performed pursuant to PCAOB standards. None of the financial relationships related to investments in Talos Energy. These matters had no impact on Talos Energy’s operations or its consolidated financial statements. Upon identification of the covered person financial relationship matters, the respective financial relationships were either disposed of or rolled over, or the individual was removed from the related non-audit service engagement team.

In 2017 and 2018, two EY professionals provided non-audit services to sister affiliates of Talos Energy causing them to be deemed covered persons pursuant to the SEC and PCAOB independence rules as it pertains to EY’s audits of Talos Energy performed pursuant to PCAOB standards. The EY professionals reported part-time dual employment with another sister affiliate of Talos Energy. Under the SEC and PCAOB auditor independence rules, covered persons cannot have employment relationships with an audit client or any affiliate of the audit client. Neither of these individuals provided service to Talos Energy. These matters had no impact on Talos Energy’s operations or its consolidated financial statements. Upon identification of the covered person employment relationship matters, the respective employment relationships were terminated in late 2017 and early 2018, respectively.

After careful consideration of the facts and circumstances and the applicable independence rules, EY has concluded that (i) the aforementioned matters will not impair EY’s ability to exercise objective and impartial judgment in connection with its audits of Talos Energy’s/Talos Energy Inc.’s consolidated financial statements and (ii) a reasonable investor with knowledge of all relevant facts and circumstances would conclude that EY has been and is capable of exercising objective and impartial judgment on all issues encompassed within its audit engagements.

The Talos board has reviewed and considered the impact that these matters may have on EY’s independence with respect to Talos under the applicable SEC and PCAOB independence rules. After considering all the facts and circumstances, the Talos board concluded that these matters have not and will not impair EY’s ability to exercise objective and impartial judgment on all issues encompassed with their audit engagements and a reasonable investor with knowledge of all relevant facts and circumstances would reach the same conclusion.

Item 15. Indemnification of Directors and Officers

The discussion below summarizes the material indemnification provisions of our Amended and Restated Certificate of Incorporation, our Amended and Restated Bylaws and Sections 102(b)(7) and 145 of the DGCL.

Section 145 of the DGCL provides that a Delaware corporation has the power, under specified circumstances, to indemnify its directors, officers, employees, and agents or persons who are or were serving at the request of the corporation as directors, officers, employees or agents of another entity. Indemnification is allowed in connection with threatened, pending, or completed actions, suits, or proceedings, whether civil, criminal, administrative or investigative, other than an action by or in the right of the corporation, brought against them by reason of the fact that they were or are directors, officers, employees, or agents, for expenses, judgments and fines, and amounts paid in settlement actually and reasonably incurred in any action, suit, or proceeding if: (i) he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and (ii) with respect to any criminal proceeding, he or she had no reasonable cause to believe that his or her conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that a person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal proceeding, had reasonable cause to believe that his or her conduct was unlawful. Indemnification is also allowed in connection with any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor against expenses (including attorneys’ fees) actually and reasonably incurred by them in connection with the defense or settlement of such action or suit if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation; provided, however, that a corporation cannot indemnify them if they have been adjudged to be liable to the corporation unless the Court of Chancery or the court in which the action or suit was brought shall determine upon application that they are fairly and reasonably entitled to indemnity for such expenses. Section 145 of the DGCL also requires a Delaware corporation to indemnify a present or former officer or director against any expenses (including attorneys’ fees) actually and reasonably incurred by such person if he or she has been successful on the merits or otherwise in defense of any action, suit or proceeding described above, or in defense of any claim, issue or matter therein.

Article VII of our Amended and Restated Certificate of Incorporation together with Article VI of our Amended and Restated Bylaws provide for mandatory indemnification of each person who was or is made a

II-1

party to or is threatened to be made a party to or is involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative or investigative because:

• the person is or was or has agreed to become a director or officer; or

• is a person who, while a director or officer, is or was serving at our request as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, other enterprise or nonprofit entity, including service with respect to an employee benefit plan, to the fullest extent permitted by the DGCL as it exists at the time the indemnification provisions of our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws were adopted or as it may be amended. However, except for proceedings to enforce rights to indemnification or advancement, we will indemnify any person in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by our board of directors.

Article VII of our Amended and Restated Certificate of Incorporation and Article VI of our Amended and Restated Bylaws provide for the advancement of reasonable expenses (including, without limitation, attorneys’ fees) reasonably incurred by any indemnified person; provided, however, that the person to whom expenses are advanced shall deliver to us a written affirmation of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification under our Amended and Restated Bylaws and a written undertaking to repay all amounts advanced if it is ultimately determined that such indemnified person is not entitled to be indemnified.

Article VII of our Amended and Restated Certificate of Incorporation and Article VI of our Amended and Restated Bylaws expressly provide that they are not the exclusive methods of indemnification.

Section 145 of the DGCL provides that a Delaware corporation has the power to purchase and maintain insurance on behalf of its directors, officers, employees or agents against liabilities asserted against such person in his or her capacity or arising out of his or her status as a director, officer, employee or agent of the company. A Delaware corporation has this power whether or not the corporation has the power to indemnify such person against the liability under Section 145 of the DGCL.

Article VI of our Amended and Restated Bylaws provides that we may purchase and maintain insurance, at our expense, to protect our self and any director or officer or of another entity against any expense, liability or loss. This insurance coverage may be maintained regardless of whether we would have the power to indemnify the person against the expense, liability or loss under our Amended and Restated Bylaws.

Section 102(b)(7) of the DGCL provides that a certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. However, that provision shall not eliminate or limit the liability of a director:

• for any breach of the director’s duty of loyalty to the corporation or its stockholders;

• for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

• under Section 174 of the DGCL, relating to liability for unlawful acquisitions or redemptions of, or payment of dividends on, capital stock; or

• for any transaction from which the director derived an improper personal benefit.

Article VII of our Amended and Restated Certificate of Incorporation contains this type of provision.

The foregoing statements are subject to the detailed provisions of Sections 145 and 102 of the DGCL and our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws.

II-2

In connection with the consummation of the Transactions, we entered into indemnification agreements with each of our executive officers and directors. These agreements require that we indemnify such individuals to the fullest extent permitted under Delaware law against liability that may arise by reason of their service to us, and to advance certain expenses incurred as a result of any proceeding against them as to which they could be indemnified.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, or otherwise, we have been informed that in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 17. Undertakings

The undersigned registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) to reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;

provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or

II-5

furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the Registration Statement.

(2) that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;

(4) that, for the purpose of determining liability under the Securities Act to any purchaser:

(i) if the registrant is subject to Rule 430B,

(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the Registration Statement as of the date the filed prospectus was deemed part of and included in the Registration Statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the Registration Statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the Registration Statement relating to the securities in the Registration Statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a Registration Statement or prospectus that is part of the Registration Statement or made in a document incorporated or deemed incorporated by reference into the Registration Statement or prospectus that is part of the Registration Statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the Registration Statement or prospectus that was part of the Registration Statement or made in any such document immediately prior to such effective date.

(5) that, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that:

(1) in a primary offering of securities of the undersigned registrant pursuant to this Registration Statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

II-6

(iv) Any other communications that is an offer in the offering made by the undersigned registrant to the purchaser.

(2) for the purpose of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

ARTICLE II

REGISTRATION RIGHTS

Section 2.01. Securities Act Registration.

(a) As promptly as reasonably practicable, but in no event later than the date that is the later of (i) thirty (30) days following the closing of the transaction contemplated by the Purchase Agreement and (ii) ten (10) Business Days after the delivery to the Company of true and complete copies of any audited financial statements of Castex Energy 2014, LLC and Castex Energy 2016, LP (which shall in each case be accompanied by an unqualified report of BDO USA, LLP) that are required to be included therein and any consents of BDO USA, LLP required under the Securities Act in connection with the filing thereof, the Company shall prepare and file with the Commission a Shelf Registration Statement (on Form S-3 if then eligible) to permit the public resale of all of the Registrable Securities in accordance with the terms of this Agreement. The Company shall use its commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective by the Commission as soon as reasonably practicable after the initial filing of the Shelf Registration Statement, but in no event more than two (2) Business Days after the date that is thirty (30) days following the filing thereof (or ninety (90) days following the filing thereof if the Commission notifies the Company that it will “Review” the Shelf Registration Statement). The Shelf Registration Statement shall provide for the resale of the Registrable Securities pursuant

to any method or combination of methods legally available to, and requested by, the Holders of any and all Registrable Securities covered by such Shelf Registration Statement. To the extent the initial Shelf Registration Statement is not made on Form S-3, the Company shall, upon becoming eligible to file a registration statement on Form S-3, prepare and file a new Shelf Registration Statement on Form S-3 to replace the initial Shelf Registration Statement and use its best efforts to cause such subsequent Shelf Registration Statement to be declared effective by the Commission as soon as reasonably practicable thereafter. The Company shall use its commercially reasonable efforts to cause any Shelf Registration Statement filed pursuant to this Section 2.01 to be continuously effective, supplemented and amended to the extent necessary to ensure that it is available for the resale of all Registrable Securities by the Holders until all Registrable Securities covered by such Shelf Registration Statement have ceased to be Registrable Securities (the “Effectiveness Period”). Such Shelf Registration Statement when effective (and all documents incorporated therein by reference) shall comply in all material respects with all applicable requirements of the Securities Act and the Exchange Act and shall not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (or, in the case of any prospectus contained in such Registration Statement, shall not include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading).

(b) Additional Demand Registration. Subject to the provisions hereof, if at any time the Company ceases to be eligible under applicable law to register resales of Registrable Securities on a Shelf Registration Statement, any one or more Holders shall have the right to require the Company to file a Registration Statement registering for sale all or part of the Registrable Securities of such Holder under the Securities Act (an “Additional Demand Registration”) by delivering a written request therefor to the Company (i) specifying the number of Registrable Securities to be included in such registration and (ii) containing all information about such Holder required to be included in such Registration Statement in accordance with applicable law. As soon as practicable after the receipt of such demand, the Company shall use commercially reasonable efforts to effect such registration (including appropriate qualification under applicable blue sky or other state securities laws and appropriate compliance with applicable regulations issued under the Securities Act and any other governmental requirements or regulations) of the Registrable Securities that the Company has been so requested to register. The Company shall not be obligated to effect more than one Additional Demand Registration pursuant to this Agreement.

(c) For so long as any Registrable Securities remain outstanding, the Company shall use its commercially reasonable efforts to (i) become eligible to register the Registrable Securities on Form S-3 (or any successor form) as promptly as practicable and (ii) thereafter maintain its eligibility to register the Registrable Securities on Form S-3 (or any successor form) until the expiration of the Effectiveness Period.

Section 2.02. Delay Rights. If the Company’s board of directors determines that the Company’s compliance with its obligations under this Article II would be materially detrimental to the Company and its shareholders because such registration would (a) materially interfere with a significant acquisition, reorganization, financing or other similar transaction involving the Company, (b) require premature disclosure of material information that the Company has a bona

fide business purpose for preserving as confidential or (c) render the Company unable to comply with applicable securities laws, then the Company shall have the right to postpone compliance with its obligations under this Article II for a period of not more than three (3) months; provided, that such right pursuant to this Section 2.02 may not be utilized more than twice in any twelve-month period.

Section 2.03. Sale Procedures. In connection with its obligations under this Article II, the Company will, as expeditiously as reasonably practicable:

(a) prepare and file with the Commission such amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such Registration Statement;

(b) furnish to each Selling Holder (i) as far in advance as reasonably practicable before filing a Registration Statement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing a Registration Statement or supplement or amendment thereto, and (ii) such number of copies of such Registration Statement and the prospectus included therein and any supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Registration Statement;

(c) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by a Registration Statement under the securities or blue sky laws of such jurisdictions as the Selling Holders; provided, however, that the Company will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of process in any jurisdiction where it is not then so subject;

(d) promptly notify each Selling Holder and each underwriter, at any time when a prospectus is required to be delivered under the Securities Act, of (i) the filing of a Registration Statement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Registration Statement or any post-effective amendment thereto, when the same has become effective; and (ii) any written comments from the Commission with respect to any filing referred to in clause (i) and any written request by the Commission for amendments or supplements to a Registration Statement or any prospectus or prospectus supplement thereto;

(e) immediately notify each Selling Holder and each underwriter, at any time when a prospectus is required to be delivered under the Securities Act, of (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in a Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; (ii) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement, or the initiation of any proceedings for that purpose; or (iii) the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, the Company agrees to, as promptly as practicable, amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading and to take such other commercially reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(f) upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to any offering of Registrable Securities;

(g) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

(h) cause all Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by the Company are then listed;

(i) use its commercially reasonable efforts to cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company to enable the Selling Holders to consummate the disposition of the Registrable Securities;

(j) provide a transfer agent and registrar for all Registrable Securities covered by a Registration Statement not later than the effective date of such Registration Statement; and

(k) enter into customary agreements and take such other actions as are reasonably requested by the Selling Holders in order to expedite or facilitate the disposition of the Registrable Securities.

Except to the extent required by applicable law, the Company shall not file any Registration Statement with respect to any Registrable Securities, or any prospectus used in connection therewith, and shall not file or make any amendment to any such Registration Statement or any amendment of or supplement to any such prospectus, that refers to any Selling Holder covered thereby by name, or otherwise identifies such Selling Holder as the holder of any securities of the Company, without the consent of such Selling Holder, such consent not to be

unreasonably withheld, conditioned or delayed, unless and to the extent such disclosure is required by law or regulation, in which case the Company shall provide written notice to such Selling Holder no less than two (2) Business Days prior to the filing of such Registration Statement or any amendment to any such Registration Statement or any prospectus used in connection therewith or any amendment of or supplement to any such prospectus.

Each Selling Holder, upon receipt of notice from the Company of the happening of any event of the kind described in subsection (e) of this Section 2.03, shall forthwith discontinue disposition of the Registrable Securities by means of a prospectus or prospectus supplement until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by subsection (e) of this Section 2.03 or until it is advised in writing by the Company that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by reference in the prospectus.

Section 2.04. Cooperation by Holders. The Company shall have no obligation to include in a Registration Statement Registrable Securities of a Selling Holder who has failed to timely furnish such information that, in the opinion of counsel to the Company, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act.

Section 2.05. Expenses.

(a) The Company will pay all reasonable Registration Expenses. Each Selling Holder shall pay all Selling Expenses in connection with any sale of its Registrable Securities hereunder.

Section 2.06. Indemnification.

(a) By the Company. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, the Company will indemnify and hold harmless each Selling Holder participating therein, its directors, officers, employees and agents, and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the “Exchange Act”), and its directors, officers, employees or agents, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder, director, officer, employee, agent or controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in such Registration Statement or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of any material fact included in any Written Testing-the-Waters Communications, any preliminary prospectus or prospectus supplement, free writing prospectus or final prospectus or prospectus supplement, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and will

reimburse each such Selling Holder, its directors, officers, employees and agents, and each such controlling Person, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings as such expenses are incurred; provided, however, that the Company will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder, its directors, officers, employees and agents or such controlling Person in writing specifically for use in any Written Testing-the-Waters Communication, a Registration Statement, any preliminary prospectus or prospectus supplement, free writing prospectus or final prospectus or prospectus supplement contained therein, or any amendment or supplement thereto, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder or any such directors, officers, employees agents or controlling Person, and shall survive the transfer of such securities by such Selling Holder.

(b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless the Company, its directors, officers, employees and agents and each Person, if any, who controls the Company within the meaning of the Securities Act or of the Exchange Act, and its directors, officers, employees and agents, to the same extent as the foregoing indemnity from the Company to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in any Written Testing-the-Waters Communication, a Registration Statement, any preliminary prospectus or prospectus supplement, free writing prospectus or final prospectus or prospectus supplement contained therein, or any amendment or supplement thereof; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification.

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission to so notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party. In any action brought against any indemnified party, the indemnified party shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.06 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense or employ counsel reasonably acceptable to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to

participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnified party shall settle any action brought against it with respect to which it is entitled to indemnification hereunder without the consent of the indemnifying party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnifying party.

(d) Contribution. If the indemnification provided for in this Section 2.06 is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall the Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of the indemnifying party on the one hand and the indemnified party on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss that is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of fraudulent misrepresentation.

(e) Other Indemnification. The provisions of this Section 2.06 shall be in addition to any other rights to indemnification or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise.

Section 2.07. Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its commercially reasonable efforts to:

(a) make and keep public information regarding the Company available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times from and after the date hereof;

(b) file with the Commission in a timely manner all reports and other documents required of the Company under the Exchange Act at all times from and after the date hereof; and

(c) so long as a Holder owns any Registrable Securities, unless otherwise available via EDGAR, furnish to such Holder forthwith upon request a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration.

Section 2.08. Transfer or Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities granted to a Holder by the Company under this Article II may be transferred or assigned by such Holder to one or more transferee(s) or assignee(s) of such Registrable Securities; provided, that (a) the Company is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee and identifying the Registrable Securities with respect to which such registration rights are being transferred or assigned, and (b) each such transferee agrees to be bound by this Agreement.

Section 3.16. Removal of Legend. The Company, at its sole cost, shall remove any legend ordinarily included on restricted securities of the Company (or instruct its transfer agent to so remove such legend) from the certificates or book-entry notations evidencing Registrable Securities if such Registrable Securities (i) are sold pursuant to an effective registration statement under the Securities Act, (ii) are sold or transferred pursuant to Rule 144 (if the transferor is not an Affiliate of the Company), or (iii) are eligible for sale without restriction and without the need for current public information pursuant to Rule 144(b) (or any successor rule) under the Securities Act. Each Holder agrees to provide the Company, its counsel and/or the transfer agent with evidence reasonably requested by it in order to cause the removal of such legend, including, as may be appropriate, any information the Company deems necessary to determine that the legend is no longer required under the Securities Act or applicable state laws, including a certification that the holder is not an Affiliate of the Company (and a covenant to inform the Company if it should thereafter become an Affiliate and to consent to exchange any certificates or instruments representing such Registrable Securities for ones bearing an appropriate restrictive legend) and regarding the length of time the Registrable Securities have been held. Any fees (with respect to the transfer agent, Company counsel or otherwise) associated with the issuance of any legal opinion required by the Company’s transfer agent or the removal of such legend shall be borne by the Company. If a legend is no longer required pursuant to the foregoing, the Company will use commercially reasonable efforts to, no later than three (3) Business Days following the delivery by a Holder to the Company or the transfer agent (with notice to the Company) of a legended certificate or instrument representing such Registrable Securities (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer) and any representation letter or certification as may be requested by the Company, deliver or cause to be delivered to such Company a certificate or instrument (as the case may be) representing such Registrable Securities that is free from all restrictive legends.

Section 3.17. Interpretation. All references to “Articles” and “Sections” shall be deemed to be references to Articles and Sections of this Agreement, unless otherwise specified. All references to instruments, documents, contracts and agreements are references to such instruments, documents, contracts and agreements as the same may be amended, supplemented and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to.” Whenever any determination, consent or approval is to be made or given by the Holders under this Agreement, such action shall be in the Holders’ sole discretion unless otherwise specified.

Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel for Talos Energy Inc., a Delaware corporation (the “Company”), with respect to certain legal matters in connection with the preparation of the Registration Statement on Form S-3 (the “Registration Statement”) filed on or about the date hereof with the Securities and Exchange Commission (the “Commission”) in connection with the registration by the Company under the Securities Act of 1933, as amended (the “Securities Act”), of the offer and sale by the selling stockholder named in the Registration Statement (the “Selling Stockholder”) of up to 4,602,460 shares of the Company’s common stock, par value $0.01 per share (the “Resale Common Stock”). We have also participated in the preparation of a Prospectus relating to the Resale Common Stock (the “Prospectus”), which is contained in the Registration Statement to which this opinion is an exhibit.

In connection with this opinion, we have assumed that the Registration Statement, and any amendments thereto (including any post-effective amendments), will have become effective.

In connection with the opinion expressed herein, we have examined, among other things, (i) the Amended and Restated Certificate of Incorporation of the Company and the Amended and Restated Bylaws of the Company, (ii) the Registration Rights Agreement, dated as of August 5, 2020, by and among the Company and the other parties listed on the signature pages thereto, (iii) the Escrow Agreement, dated as of June 19, 2020, by and among Talos Production Inc., Castex Energy Partners, LLC, Castex Offshore, Inc. and Citibank, N.A. as escrow agent, (iv) the records of corporate proceedings that have occurred prior to the date hereof with respect to the Registration Statement, (v) the Registration Statement and (vi) the Prospectus. We have also reviewed such questions of law as we have deemed necessary or appropriate. As to matters of fact relevant to the opinion expressed herein, and as to factual matters arising in connection with our examination of corporate documents, records and other documents and writings, we have relied upon certificates and other communications of corporate officers of the Company, without further investigation as to the facts set forth therein.

September 11, 2020    Page 2

In connection with rendering the opinions set forth below, we have assumed that (i) all information contained in all documents reviewed by us is true and correct; (ii) all signatures on all documents examined by us are genuine; (iii) all documents submitted to us as originals are authentic and all documents submitted to us as copies conform to the originals of those documents; (iv) each person signing the documents that we reviewed has the legal capacity and authority to do so; (v) the Registration Statement and any subsequent amendments (including any post-effective amendments), will be effective and comply with all applicable laws and (vi) all Resale Common Stock will be issued and/or sold in compliance with applicable federal and state securities laws and in the manner specified in the Registration Statement and any applicable prospectus supplement to the Prospectus.

Based on the foregoing, and subject to the assumptions, qualifications, limitations, and exceptions set forth herein, we are of the opinion that:

1.    The shares of Resale Common Stock proposed to be sold by the Selling Stockholder have been duly authorized and validly issued and are fully paid and nonassessable.

The foregoing opinion is limited in all respects to the General Corporation Law of the State of Delaware (including the applicable provisions of the Delaware Constitution and the reported judicial decisions interpreting these laws) and the federal laws of the United States of America, and we do not express any opinions as to the laws of any other jurisdiction, domestic or foreign. We express no opinions concerning the enforceability of indemnification provisions to the extent they purport to relate to liabilities resulting from or based upon negligence or any violation of federal or state securities or blue sky laws.

We hereby consent to the statements with respect to us under the heading “Legal Matters” in the Prospectus forming a part of the Registration Statement and to the filing of this opinion as an exhibit to the Registration Statement. In giving this consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act and the rules and regulations thereunder.

Very truly yours,

/s/ Vinson & Elkins L.L.P.
