ABOUT THIS PROSPECTUS

        This prospectus is part of an automatic shelf registration statement that we filed with the Securities and Exchange Commission (the "SEC") as a "well-known seasoned issuer" as defined in Rule 405 under the Securities Act of 1933, as amended (the "Securities Act"). Under the automatic shelf registration process, we and the selling stockholders named herein may offer and sell, from time to time, shares of our common stock.

Each time we or any selling stockholder offer to sell common stock, we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement that accompanies this prospectus may describe, as applicable: the public offering price, the price paid for the securities, the net proceeds and the other specific terms related to the offering of these securities. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to these offerings. The prospectus supplement and any related free writing prospectus may also add to, update or change information contained in this prospectus or in any documents that we have incorporated by reference into this prospectus and, accordingly, to the extent inconsistent, information in this prospectus is superseded by the information in the prospectus supplement or any related free writing prospectus.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

        The information in this prospectus, including in the documents incorporated by reference herein, includes forward-looking statements within the meaning of Section 27A of the Securities Act, Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical fact contained in this prospectus and the documents incorporated by reference into it, 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, the words "could," "believe," "anticipate," "intend," "estimate," "expect," "project" and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on management's current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. When considering forward-looking statements, you should keep in mind the risk factors and other cautionary statements described under "Risk Factors" in this prospectus, the accompanying prospectus supplement, our most recent Annual Report on Form 10-K (the "Form 10-K"), any subsequent Quarterly Report on Form 10-Q and any Current Report on Form 8-K incorporated by reference herein. Should one or more of these risks or uncertainties occur, or should underlying assumptions prove incorrect, our actual results and plans could differ materially from those expressed in any forward looking statements.

        Forward-looking statements may include statements about:

•

our business strategy;



•

our reserves;



•

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



•

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



•

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



•

our realized oil, natural gas liquid ("NGL") and natural gas prices;



•

the timing and amount of future production of oil, NGLs and natural gas;



•

our hedging strategy and results;



•

our future drilling plans;



•

our competition and government regulations;



•

our ability to obtain permits and governmental approvals;



•

our pending legal or environmental matters;



•

our marketing of oil, NGLs and natural gas;



•

our leasehold or business acquisitions;



•

costs of developing our properties;



•

general economic conditions;



•

credit markets;



•

uncertainty regarding our future operating results; and



•

our plans, objectives, expectations and intentions that are not historical.

Table of Contents

        We caution you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond our control, incident to the exploration for and development, production, gathering and sale of oil, NGLs and natural gas. These risks include, but are not limited to, commodity price volatility, inflation, lack of availability of drilling and production equipment and services, environmental risks, drilling and other operating risks, regulatory changes, the uncertainty inherent in estimating reserves and in projecting future rates of production, cash flow and access to capital, the timing of development expenditures and the other risks described under "Risk Factors" in this prospectus, the accompanying prospectus supplement, the Form 10-K, any subsequent Quarterly Report on Form 10-Q and any Current Report on Form 8-K incorporated by reference herein.

        Reserve engineering is a process of estimating underground accumulations of oil, NGLs and natural gas 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 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, NGLs and natural gas that are ultimately recovered.

        All forward-looking statements, expressed or implied, attributable to us or persons acting on our behalf 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 they are made. 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.

RISK FACTORS

        Investing in our common stock involves a high degree of risk. Before deciding whether to purchase shares of our common stock, you should carefully consider the risks and uncertainties described under "Risk Factors" in the Form 10-K, any subsequent Quarterly Reports on Form 10-Q, any Current Report on Form 8-K incorporated by reference herein and the accompanying prospectus supplement, together with all of the other information included in, or incorporated by reference into, this prospectus and in the accompanying prospectus supplement.

Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations.

DESCRIPTION OF CAPITAL STOCK

General

        Our authorized capital stock consists of 300,000,000 shares of common stock, $0.01 par value per share, of which 78,267,452 shares are issued and outstanding as of March 12, 2015 (including 1,041,766 shares of restricted stock that have been awarded to our directors and certain of our employees and consultants), and 15,000,000 shares of preferred stock, $0.01 par value per share, of which no shares are issued and outstanding.

        The following summary of our capital stock and our amended and restated certificate of incorporation and our amended and restated bylaws does not purport to be complete and is qualified in its entirety by reference to the provisions of applicable law and to our amended and restated certificate of incorporation and our amended and restated bylaws.

Common Stock

        Except as provided by law or in a preferred stock designation, holders of common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders, have the exclusive right to vote for the election of directors and do not have cumulative voting rights. Except as otherwise required by law, holders of common stock are not entitled to vote on any amendment to the amended and restated certificate of incorporation (including any certificate of designations relating to any series of preferred stock) that relates solely to the terms of any 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 thereon pursuant to our amended and restated certificate of incorporation (including any certificate of designations relating to any series of preferred stock) or pursuant to the General Corporation Law of the State of Delaware (the "DGCL"). Subject to prior rights and preferences that may be applicable to any outstanding shares or series of preferred stock, holders of common stock are entitled to receive ratably in proportion to the shares of common stock held by them such dividends (payable in cash, stock or otherwise), if any, as may be declared from time to time by our board of directors out of funds legally available for dividend payments. All outstanding shares of common stock are fully paid and non-assessable, and the shares of common stock to be issued upon completion of this offering will be fully paid and non-assessable.

        The holders of common stock have no preferences or rights of conversion, exchange, preemption or other subscription rights. There are no redemption or sinking fund provisions applicable to our common stock. In the event of any voluntary or involuntary liquidation, dissolution or winding-up of our affairs, holders of common stock will be entitled to share ratably in our assets in proportion to the shares of common stock held by them that are remaining after payment or provision for payment of all of our debts and obligations and after distribution in full of preferential amounts to be distributed to holders of outstanding shares of preferred stock, if any.

Preferred Stock

        Our amended and restated certificate of incorporation authorizes our board of directors, subject to any limitations prescribed by law, without further stockholder approval, to establish and to issue from time to time one or more classes or series of preferred stock, par value $0.01 per share, covering up to an aggregate of 15,000,000 shares of preferred stock. Each class or series of preferred stock will cover the number of shares and will have the powers, preferences, rights, qualifications, limitations and restrictions determined by our board of directors, which may include, among others, dividend rights, liquidation preferences, voting rights, conversion rights, preemptive rights and redemption rights. Except as provided by law or in a preferred stock designation, the holders of preferred stock are not entitled to vote at or receive notice of any meeting of stockholders.

Anti-Takeover Effects of Delaware Law, Our Amended and Restated Certificate of Incorporation and Our Amended and Restated Bylaws

        Some provisions of Delaware law, our amended and restated certificate of incorporation and our amended and restated bylaws contain provisions that could make the following transactions more difficult: acquisitions of us by means of a tender offer, a proxy contest or otherwise or removal of our incumbent officers and directors. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best interest or in our best interests, including transactions that might result in a premium over the market price for our shares.

        These provisions are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with us. We believe that the benefits of increased protection and our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because, among other things, negotiation of these proposals could result in an improvement of their terms.

Delaware Law

        Our amended and restated certificate of incorporation provides that we are not governed by Section 203 of the DGCL, which, in the absence of such provisions, would have imposed additional requirements regarding mergers and other business combinations. Section 203 of the DGCL prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder, unless:

•

the transaction is approved by the board of directors before the date the interested stockholder attained that status;



•

upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced; or



•

on or after such time the business combination is approved by the board of directors and authorized at a meeting of stockholders by at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.

        An interested stockholder is defined as a person who, together with any affiliates or associates of such person, beneficially owns, directly or indirectly, 15% or more of the outstanding voting shares of a Delaware corporation. The term "business combination" is broadly defined to include a broad array of transactions, including mergers, consolidations, sales or other dispositions of assets having a total value in excess of 10% of the consolidated assets of the corporation or all of the outstanding stock of the corporation, and some other transactions that would increase the interested stockholder's proportionate share ownership in the corporation.

Our Amended and Restated Certificate of Incorporation and Our Amended and Restated Bylaws

        Provisions of our amended and restated certificate of incorporation and our amended and restated bylaws may delay or discourage transactions involving an actual or potential change in control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock.

Table of Contents

        Among other things, our amended and restated certificate of incorporation and amended and restated bylaws:

•

establish advance notice procedures with regard to stockholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of our stockholders. These procedures provide that notice of stockholder proposals must be timely given in writing to our corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the annual meeting for the preceding year. Our amended and restated bylaws specify the requirements as to form and content of all stockholders' notices. These requirements may preclude stockholders from bringing matters before the stockholders at an annual or special meeting;

provide our board of directors the ability to authorize undesignated preferred stock. This ability makes it possible for our board of directors to issue, without stockholder approval, preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of us. These and other provisions may have the effect of deferring hostile takeovers or delaying changes in control or management of our company;

•

provide that the authorized number of directors may be changed only by resolution of our board of directors;



•

provide that all vacancies, including newly created directorships, may, except as otherwise required by law or, if applicable, the rights of holders of a series of preferred stock, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum;



•

provide that any action required or permitted to be taken by the stockholders must be effected at a duly called annual or special meeting of stockholders and may not be effected by any consent in writing in lieu of a meeting of such stockholders, subject to the rights of the holders of any series of preferred stock with respect to such series;



•

provide that our certificate of incorporation and bylaws may be amended by the affirmative vote of the holders of at least two-thirds of our then outstanding common stock;



•

provide that special meetings of our stockholders may only be called by our board of directors, our chief executive officer or the chairman of our board of directors;



•

provide for our board of 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 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;



•

provide that we renounce any interest in existing and future investments in other entities by, or the business opportunities of, the Sponsors (as defined in our amended and restated certificate of incorporation) or any of their officers, directors, agents, stockholders, members, partners, affiliates and subsidiaries (other than our directors that are presented business opportunities in their capacity as our directors) and that they have no obligation to offer us those investments or opportunities; and



•

provide that our bylaws can be amended by our board of directors.

Forum Selection

        Our amended and restated certificate of incorporation provides that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for:

•

any derivative action or proceeding brought on our behalf;



•

any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders;



•

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



•

any action asserting a claim against us that is governed by the internal affairs doctrine, in each such case subject to such Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein.

        Our amended and restated certificate of incorporation also provides that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of, and to have consented to, this forum selection provision. Although we believe these provisions will benefit us by providing increased consistency in the application of Delaware law for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against our directors, officers, employees and agents. 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 our amended and restated certificate of incorporation is inapplicable or unenforceable.

Limitations of Liability and Indemnification Matters

        Our amended and restated certificate of incorporation limits the liability of our directors for monetary damages for breach of their fiduciary duty as directors, except for liability that cannot be eliminated under the DGCL. Delaware law provides that directors of a company will not be personally liable for monetary damages for breach of their fiduciary duty as directors, except for liabilities:

•

for any breach of their duty of loyalty to us or our stockholders;



•

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



•

for unlawful payment of dividend or unlawful stock repurchase or redemption, as provided under Section 174 of the DGCL; or



•

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

        Any amendment, repeal or modification of these provisions will be prospective only and would not affect any limitation on liability of a director for acts or omissions that occurred prior to any such amendment, repeal or modification.

        Our amended and restated bylaws also provide that we will indemnify our directors and officers to the fullest extent permitted by Delaware law. If Delaware law is amended to authorize corporate action further eliminating or limiting the personal liability of a director, then the liability of our directors will be eliminated or limited to the fullest extent permitted by Delaware law, as so amended. Our amended and restated bylaws also permit us to purchase insurance on behalf of any officer, director, employee or other agent for any liability arising out of that person's actions as our officer, director, employee or agent, regardless of whether Delaware law would permit indemnification. We have entered into

7

Table of Contents

indemnification agreements with each of our directors and officers. These agreements require us to indemnify these individuals to the fullest extent permitted under Delaware law against liability that may arise by reason of their service to us, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified. We believe that the limitation of liability provision in our amended and restated certificate of incorporation and the indemnification agreements facilitates our ability to continue to attract and retain qualified individuals to serve as directors and officers.

        The limitation of liability and indemnification provisions in our certificate of incorporation and bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against directors and officers, even though an action, if successful, might benefit us and our stockholders. A stockholder's investment may be harmed to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have 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. There is no pending litigation or proceeding naming any of our directors or officers as to which indemnification is being sought, nor are we aware of any pending or threatened litigation that may result in claims for indemnification by any director or officer.

Transfer Agent and Registrar

        The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC.

Listing

        Our common stock is listed on the New York Stock Exchange under the symbol "RSPP."

        In January 2014, in connection with our IPO, we entered into the following transactions with the selling stockholders:

•

We acquired net profits interests in oil and natural gas properties in the Permian Basin from ACTOIL, LLC in exchange for 10,816,626 shares of our common stock.



•

We acquired working interests in certain acreage and wells in the Permian Basin from Rising Star Energy Development Co., L.L.C. ("Rising Star") in exchange for 1,793,123 shares of the our common stock and the right to receive approximately $1.7 million in cash. Rising Star's sole member and the general partner of Rising Star's sole member are owned by Natural Gas Partners VIII, L.P., certain members of our management team and certain other persons. In January 2015, Rising Star distributed all of its shares of the Company's common stock to its sole member, which in turn distributed all such shares to its limited partners (including Natural Gas Partners VIII, L.P.) and to its general partner, which in turn made a distribution to its members (including Natural Gas Partners VIII, L.P.), on a pro rata basis. In connection with such distribution, Rising Star assigned its rights and obligations under the Stockholders' Agreement (defined and described below) to Natural Gas Partners VIII, L.P. and all of its rights and obligations under the Registration Rights Agreement to all of the persons who received shares of the Company's common stock from Rising Star's sole member or the general partner of Rising Star's sole member.



•

The members of RSP Permian, L.L.C. contributed all of their interests in RSP Permian, L.L.C. to RSP Permian Holdco, L.L.C., a newly formed entity that is wholly owned by such members, and RSP Permian Holdco, L.L.C. contributed all of its interests in RSP Permian, L.L.C. to us in exchange for 28,536,427 shares of our common stock, an assignment of RSP Permian, L.L.C.'s pro rata share of an escrow related to a disposition of certain working interests and the right to receive approximately $27.7 million in cash. RSP Permian Holdco, L.L.C. is owned by Production Opportunities II, L.P., certain members of our management team and certain of our employees. In December 2014, in anticipation of RSP Permian Holdco, L.L.C.'s pending liquidation, RSP Permian Holdco, L.L.C. distributed of all of its shares of the Company's common stock to its members (including Production Opportunities II, L.P.), on a pro rata basis. In connection with such distribution, RSP Permian Holdco, L.L.C. assigned all of its rights and obligations under the Stockholders' Agreement to Production Opportunities II, L.P. and all of its rights and obligations under the Registration Rights Agreement to its members.

Stockholders' Agreement

        We are party to a stockholders' agreement (the "Stockholders' Agreement") with Production Opportunities II, L.P., Natural Gas Partners VIII, L.P. and certain other stockholders. We entered into the Stockholders' Agreement on January 23, 2014 in connection with our IPO. The Stockholders' Agreement provides Production Opportunities II, L.P., Ted Collins, Jr. and Wallace Family Partnership, LP with the right to designate a certain number of nominees to our board of directors, subject to certain ownership requirements. Production Opportunities II, L.P., in particular, has the right to designate two nominees to our board of directors if it and its affiliates own 15% or more of the outstanding shares of our common stock and the right to designate one nominee if it and its affiliates own less than 15% but more than 5% of the outstanding shares of our common stock. In addition, pursuant to the Stockholders' Agreement, for so long as Production Opportunities II, L.P. and its affiliates collectively own 15% or more of the outstanding shares of our common stock, any committee of our board of directors is to include in its membership at least one director designated by Production Opportunities II, L.P., except to the extent that such membership would violate applicable securities laws or stock exchange rules.

        As a result of an underwritten public offering of our common stock by us and certain of our stockholders in August 2014, Production Opportunities II, L.P. and its affiliates owned less than 15% (but more than 5%) of the outstanding shares of our common stock and therefore lost the right to have one of its nominees serve on each committee of our board of directors as well as the right to designate two nominees. However, the other parties to the Stockholders' Agreement, including us, waived the requirement to have a nominee of Production Opportunities II, L.P. tender his resignation to our board of directors.

securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and the applicable prospectus supplement or pricing supplement, as the case may be.

        If required by applicable law, a prospectus supplement will state the terms of the offering of the securities, including:

•

the name or names of any participating underwriters, brokers, dealers or agents and the amounts of securities underwritten or purchased by each of them, if any;

the public offering price or purchase price of the securities and the net proceeds to be received by us and/or the selling stockholders from the sale;

other material terms of the offering.

        The offer and sale of the securities described in this prospectus by us, the selling stockholders, the underwriters or the third parties described above may be effected from time to time in one or more transactions, including privately negotiated transactions, either:

•

at a fixed price or prices, which may be changed;

General

        Any public offering price and any discounts, commissions, concessions or other items constituting compensation allowed or reallowed or paid to underwriters, dealers, agents or remarketing firms may be changed from time to time. Any selling stockholders, underwriters, dealers, agents and remarketing firms that participate in the distribution of the offered securities may be "underwriters" as defined in the Securities Act. Any discounts or commissions they receive from us or the selling stockholders and any profits they receive on the resale of the offered securities may be treated as underwriting discounts and commissions under the Securities Act. We and the selling stockholders will identify any underwriters, agents or dealers and describe their commissions, fees or discounts in the applicable prospectus supplement or pricing supplement, as the case may be.

        We, the selling stockholders and other persons participating in the sale or distribution of the securities will be subject to applicable provisions of the Exchange Act, and the rules and regulations thereunder, including Regulation M. This regulation may limit the timing of purchases and sales of any

14

Table of Contents

of the securities by us and/or the selling stockholders or any other person. The anti-manipulation rules under the Exchange Act may apply to sales of securities in the market and to the activities of us and the selling stockholders and any affiliates of ours and the selling stockholders. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution for a period of up to five business days before the distribution. These restrictions may affect the marketability of the securities and the ability of any person or entity to engage in market-making activities with respect to the securities.

        We and the selling stockholders are not restricted as to the price or prices at which we may sell the securities. Sales of such securities may have an adverse effect on the market price of the securities.

        Moreover, it is possible that a significant number of shares of common stock could be sold at the same time, which may have an adverse effect on the market price of the securities.

        We cannot assure you that we or the selling stockholders will sell all or any portion of the securities offered hereby.

Underwriters and Agents

        If underwriters are used in a sale, they will acquire the offered securities for their own account. The underwriters may resell the offered securities in one or more transactions, including negotiated transactions. These sales may be made at a fixed public offering price or prices, which may be changed, at market prices prevailing at the time of the sale, at prices related to such prevailing market prices or at negotiated prices. We and the selling stockholders may offer the securities to the public through an underwriting syndicate or through a single underwriter. The underwriters in any particular offering will be mentioned in the applicable prospectus supplement or pricing supplement, as the case may be.

        Unless otherwise specified in connection with any particular offering of securities, the obligations of the underwriters to purchase the offered securities will be subject to certain conditions contained in an underwriting agreement that we and the applicable selling stockholders, if any, will enter into with the underwriters at the time of the sale to them. The underwriters will be obligated to purchase all of the securities of the series offered if any of the securities are purchased, unless otherwise specified in connection with any particular offering of securities. Any initial offering price and any discounts or concessions allowed, reallowed or paid to dealers may be changed from time to time.

        We and the selling stockholders may designate agents to sell the offered securities. Unless otherwise specified in connection with any particular offering of securities, the agents will agree to use their best efforts to solicit purchases for the period of their appointment. We and the selling stockholders may also sell the offered securities to one or more remarketing firms, acting as principals for their own accounts or as agents for us or any selling stockholders. These firms will remarket the offered securities upon purchasing them in accordance with a redemption or repayment pursuant to the terms of the offered securities. A prospectus supplement or pricing supplement, as the case may be, will identify any remarketing firm and will describe the terms of its agreement, if any, with us and/or the selling stockholders and its compensation.

        In connection with offerings made through underwriters or agents, we and the selling stockholders may enter into agreements with such underwriters or agents pursuant to which we and the selling stockholders receive outstanding securities in consideration for the securities being offered to the public for cash. In connection with these arrangements, the underwriters or agents may also sell securities covered by this prospectus to hedge their positions in these outstanding securities, including in short sale transactions. If so, the underwriters or agents may use the securities received from us or the selling stockholders under these arrangements to close out any related open borrowings of securities.

Table of Contents

Dealers

        We and the selling stockholders may sell the offered securities to dealers as principals. We and the selling stockholders may negotiate and pay dealers' commissions, discounts or concessions for their services. The dealer may then resell such securities to the public either at varying prices to be determined by the dealer or at a fixed offering price agreed to with us and/or the selling stockholders at the time of resale. Dealers engaged by us or the selling stockholders may allow other dealers to participate in resales.

Direct Sales

        We and the selling stockholders may choose to sell the offered securities directly. In this case, no underwriters or agents would be involved.

Institutional Purchasers

        We and the selling stockholders may authorize agents, dealers or underwriters to solicit certain institutional investors to purchase offered securities on a delayed delivery basis pursuant to delayed delivery contracts providing for payment and delivery on a specified future date. The applicable prospectus supplement or pricing supplement, as the case may be will provide the details of any such arrangement, including the offering price and commissions payable on the solicitations.

        We and the selling stockholders will enter into such delayed contracts only with institutional purchasers that we or the selling stockholders approve. These institutions may include commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions.

Indemnification; Other Relationships

        We and the selling stockholders may have agreements with agents, underwriters, dealers and remarketing firms to indemnify them against certain civil liabilities, including liabilities under the Securities Act. Agents, underwriters, dealers and remarketing firms, and their affiliates, may engage in transactions with, or perform services for, us or the selling stockholders in the ordinary course of business. This includes commercial banking and investment banking transactions.

        We may agree to indemnify in certain circumstances the selling stockholders against certain liabilities, including liabilities under the Securities Act. The selling stockholders may agree to indemnify us in certain circumstances against certain liabilities, including liabilities under the Securities Act.

Market-Making; Stabilization and Other Transactions

        In connection with any offering of common stock, the underwriters may purchase and sell shares of common stock in the open market. These transactions may include short sales, syndicate covering transactions and stabilizing transactions. Short sales involve syndicate sales of common stock in excess of the number of shares to be purchased by the underwriters in the offering, which creates a syndicate short position. "Covered" short sales are sales of shares made in an amount up to the number of shares represented by the underwriters' over-allotment option. In determining the source of shares to close out the covered syndicate short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. Transactions to close out the covered syndicate short involve either purchases of the common stock in the open market after the distribution has been completed or the exercise of the over-allotment option. The underwriters may also make "naked" short sales of shares in excess of the overallotment option. The underwriters must close out any naked short position by purchasing shares of common stock in the open market. A naked short position is more

likely to be created if the underwriters are concerned that there may be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of bids for or purchases of shares in the open market while the offering is in progress for the purpose of pegging, fixing or maintaining the price of the securities.

        In connection with any offering, the underwriters may also engage in penalty bids. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

Fees and Commissions

        We will pay the expenses, other than underwriting discounts and commissions, associated with the registration and sale of shares to be sold by the selling stockholders. The selling stockholders will pay any underwriting discounts or selling commissions for such sales.

        Pursuant to a requirement by the Financial Industry Regulatory Authority, Inc. ("FINRA"), the maximum commission or discount to be received by any FINRA member or independent broker-dealer in connection with the sale of any securities being registered by this prospectus may not be greater than eight percent of the offering proceeds received by us and any selling stockholders.

        If 5% or more of the net proceeds of any offering of securities made under this prospectus will be received by FINRA members participating in the offering or affiliates or associated persons of such FINRA members, the offering will be conducted in accordance with FINRA Rule 5121.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14.    Other Expenses of Issuance and Distribution

        The following table sets forth the costs and expenses, other than underwriting discounts and commissions, payable by us in connection with the sale and distribution of the common stock being registered.

Item 15.    Indemnification of Directors and Officers

        Section 145 of the DGCL provides that a corporation may indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise), against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. A similar standard is applicable in the case of derivative actions (i.e., actions by or in the right of the corporation), except that indemnification extends only to expenses, including attorneys' fees, incurred in connection with the defense or settlement of such action and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation.

        Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that limit the liability of our directors and officers for monetary damages to the fullest extent

II-1

Table of Contents

permitted by the DGCL. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except liability:

•

for any breach of the director's duty of loyalty to our company or our stockholders;



•

for any act or omission not in good faith or that involve intentional misconduct or knowing violation of law;



•

under Section 174 of the DGCL regarding unlawful dividends and stock purchases; or



•

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

        Any amendment to, or repeal of, these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to that amendment or repeal. If the DGCL is amended to provide for further limitations on the personal liability of directors or officers of corporations, then the personal liability of our directors and officers will be further limited to the fullest extent permitted by the DGCL.

        In addition, we have entered into indemnification agreements with our current directors and officers containing provisions that are in some respects broader than the specific indemnification provisions contained in the DGCL. The indemnification agreements require us, among other things, to indemnify our directors against certain liabilities that may arise by reason of their status or service as directors and to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified. We also intend to enter into indemnification agreements with our future directors and officers.

        We maintain liability insurance policies that indemnify our directors and officers against various liabilities, including certain liabilities under arising under the Securities Act and the Securities Exchange Act, as amended (the "Exchange Act"), that may be incurred by them in their capacity as such.

        Any underwriting agreement that we enter into in connection with the sale of the common stock being registered may provide for indemnification of our directors and certain of our officers by the underwriters against certain liabilities.

        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, 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 16.    Exhibits

        Reference is made to the Exhibit Index following the signature pages hereto, which Exhibit Index is incorporated by reference into this Item.

Item 17.    Undertakings

        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:

        (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 the 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 the 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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 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 the registration statement or any material change to such information in the registration statement;

Provided, however, that paragraphs (i), (ii) and (iii) of this section 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 furnished to the SEC 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)  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

         (ii)  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 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 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

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

        (6)   That, for purposes 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 Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Exchange Act) 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.

Re: Registration Statement on Form S-3

Ladies and Gentlemen:

        We have acted as counsel for RSP Permian, Inc., a Delaware corporation (the "Company"), with respect to certain legal matters in connection with the preparation of a registration statement on Form S-3 (the "Registration Statement") filed on March 17, 2015 with the Securities and Exchange Commission (the "Commission") in connection with the registration by the Company under the Securities Act of 1933 (the "Securities Act") of the offer and sale, from time to time, pursuant to Rule 415 of the Securities Act, by:

(i)

the Company of shares (the "Primary Shares") of the Company's common stock, par value $0.01 per share (the "Common Stock"); and



(ii)

the stockholders named as the Selling Stockholders in the Registration Statement of up to (a) 4,600,000 shares of Common Stock (the "Resale Shares" and, together with the Primary Shares, the "Securities").

        We have also participated in the preparation of the prospectus contained in the Registration Statement (the "Prospectus"). The Securities will be offered in amounts, at prices and on terms to be determined in light of market conditions at the time of sale and to be set forth in supplements (each a "Prospectus Supplement") to the Prospectus.

        In rendering the opinions set forth below, we have reviewed and relied upon (i) the Company's Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, (ii) the Registration Statement, including the Prospectus, (iii) certain records of corporate proceedings that have occurred prior to the filing of the Registration Statement, including the resolutions of the board of directors of the Company relating to the Registration Statement, and (iv) such other certificates, statutes and other instruments and documents as we considered necessary or appropriate for the purpose of rendering the opinions set forth below. In addition, we have reviewed such questions of law as we considered necessary or appropriate. As to matters of fact relevant to the opinions expressed below, and as to factual matters arising in connection with our review 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.

        For purposes of rendering the opinions set forth below, we have made the following assumptions:

(i)

the Registration Statement, and any amendments thereto (including post-effective amendments), will have become effective;



(ii)

a Prospectus Supplement will have been prepared and filed with the Commission describing the Securities offered thereby;



(iii)

each document submitted to us for review is accurate and complete, each such document that is an original is authentic, each such document that is a copy conforms to an authentic original, and all signatures on each such document are genuine;

   

---

(iv)

each person signing the documents that we reviewed has the legal capacity and authority to do so;



(v)

each certificate from governmental officials reviewed by us is accurate, complete and authentic, and all official public records are accurate and complete;



(vi)

all Securities will be issued and sold in compliance with applicable federal and state securities laws and all requirements and restrictions, if any, applicable to the Company, whether imposed by any agreement or instrument to which the Company is a party or by which it is bound or any court or other governmental or regulatory body having jurisdiction over the Company, and in the manner stated in the Registration Statement, the Prospectus and the applicable Prospectus Supplement;



(vii)

at the time of the issuance of the Primary Shares, the Company will validly exist and be duly qualified and in good standing under the laws of the State of Delaware and the Company will have the necessary organizational power and authority to issue the Primary Shares;



(viii)

at the time of any offering or sale of any Primary Shares, the Company will have authorized or created and made available for issuance the number of shares of Common Stock set forth in such offering or sale; and



(ix)

any definitive purchase, underwriting or similar agreement with respect to the Securities offered will have been duly authorized and validly executed and delivered by the Company and the other parties thereto.

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

(1)

The Primary Shares will be duly authorized and validly issued, fully paid and non-assessable when (a) the board of directors of the Company (the "Board") has taken all necessary corporate action to approve the issuance and terms of the offering thereof and related matters, and (b) certificates representing the Primary Shares have been duly executed, registered and delivered in accordance with any applicable definitive purchase, underwriting or similar agreement approved by the Board upon payment of the consideration therefor provided for therein (provided that such consideration is not less than the aggregate par value of the Primary Shares); and



(2)

The Resale Shares have been duly authorized and are validly issued, fully paid and non-assessable.

        Our opinion is qualified in the following respects:

(i)

we express no opinion 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;



(ii)

our opinions herein are limited in all respects to the General Corporation Law of the State of Delaware, which includes those statutory provisions as well as all applicable provisions of the Delaware Constitution and the reported judicial decisions interpreting such laws, and the federal laws of the United States of America, and we do not express any opinion as to the applicability of, or the effect thereon, of the laws of any other jurisdiction;



(iii)

we express no opinion as to any matter other than as set forth herein, and no opinion may be inferred or implied herefrom; and



(iv)

our opinion is given as of the date hereof, and we undertake no, and hereby disclaim any, obligation to advise you of any change in any matter set forth herein.

        We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of our name in the Prospectus forming a part of the Registration Statement under the caption "Legal Matters." By giving such consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission issued thereunder.
