ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the U.S. Securities and Exchange Commission, or the SEC, as a "well-known seasoned issuer" as defined in Rule 405 under the Securities Act of 1933, as amended, using a "shelf" registration process. By using a shelf registration statement, we may sell securities from time to time and in one or more offerings and the selling securityholders to be named in a supplement to this prospectus may, from time to time, sell shares of common stock from time to time in one or more offerings as described in this prospectus. Each time that we or the selling securityholders offer and sell securities, we or the selling securityholders will provide a prospectus supplement to this prospectus that contains specific information about the securities being offered and sold and the specific terms of that offering. 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 or free writing prospectus may also add, update or change information contained in this prospectus with respect to that offering. If there is any inconsistency between the information in this prospectus and the applicable prospectus supplement or free writing prospectus, you should rely on the prospectus supplement or free writing prospectus, as applicable.

We and the selling securityholders will not make an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus and the applicable prospectus supplement to this prospectus is accurate only as of the date on its respective cover, that the information appearing in any applicable free writing prospectus is accurate only as of the date of that free writing prospectus, and that any information incorporated by reference is accurate only as of the date of the document incorporated by reference, unless we indicate otherwise. Our business, financial condition, results of operations and prospects may have changed since those dates. This prospectus incorporates by reference, and any prospectus supplement or free writing prospectus may contain and incorporate by reference, market data and industry statistics and forecasts that are based on independent industry publications and other publicly available information. Although we believe these sources are reliable, we do not guarantee the accuracy or completeness of this information and we have not independently verified this information. In addition, the market and industry data and forecasts that may be included or incorporated by reference in this prospectus, any prospectus supplement or any applicable free writing prospectus may involve estimates, assumptions and other risks and uncertainties and are subject to change based on various factors, including those discussed under the heading "Risk Factors" contained in this prospectus, the applicable prospectus supplement and any applicable free writing prospectus, and under similar headings in other documents that are incorporated by reference into this prospectus. Accordingly, investors should not place undue reliance on this information.

THE COMPANY

We are a growth-oriented, Midland, Texas-based oilfield services company providing hydraulic fracturing and other complementary services to leading upstream oil and gas companies engaged in the exploration and production ("E&P") of North American unconventional oil and natural gas resources. Our operations are primarily focused in the Permian Basin, where we have cultivated long-standing customer relationships with some of the region's most active and well-capitalized E&P companies. The Permian Basin is widely regarded as the most prolific oil-producing area in the United States, and we believe we are currently one of the largest providers of hydraulic fracturing services in the region by hydraulic horsepower, or HHP, with a current aggregate deployed capacity of 815,000 HHP.

In addition to our core hydraulic fracturing operations, we also offer a suite of complementary well completion and production services, including cementing, acidizing, coiled tubing, flowback services, surface air drilling and Permian drilling. We believe these complementary services create operational efficiencies for our customers and allow us to capture a greater portion of their capital spending across the lifecycle of an unconventional well.

We filed our certificate of incorporation with the Secretary of State of Delaware on March 16, 2017.

Our principal executive offices are located at 1706 S. Midkiff, Bldg. B, Midland, Texas 79701, and our telephone number is (432) 688-0012.

COMMAND=STYLE_ADDED,"margin-left:10.0pt;text-indent:-10.0pt;" 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 shareholder, 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 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 the certificate of incorporation (including any certificate of designations relating to any series of preferred stock) or pursuant to the Delaware General Corporation Law (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. 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 the 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.

COMMAND=STYLE_ADDED,"margin-left:10.0pt;text-indent:-10.0pt;" Registration Rights Agreement

We have entered into a registration rights agreement with certain shareholders, including Energy Capital Partners II, LP, or Energy Capital Partners, and Special Situations Fund III, L.P. Pursuant to this registration rights agreement, we are required to cause a shelf registration statement to be filed as soon as permitted by the applicable securities laws. Also pursuant to the registration rights agreement, certain shareholders have the right to demand we undertake an underwritten offering of such shareholders' shares of our common stock at any time after the first anniversary of the consummation of our IPO. Pursuant to this provision, Energy Capital Partners has the right to demand up to five underwritten offerings, and Special Situations Fund III, L.P. has the right to demand up to two underwritten offerings, so long as the minimum expected offering price is $15 million. In addition, shareholders have certain "piggyback" rights when we undertake an underwritten offering of shares of our common stock, subject to customary cutbacks.

COMMAND=STYLE_ADDED,"margin-left:10.0pt;text-indent:-10.0pt;" Stockholders Agreement

We have entered into a stockholders agreement with Energy Capital Partners that provides Energy Capital Partners and its affiliates who hold our shares certain rights to designate nominees for election to our board of directors. The stockholders agreement provides that, subject to compliance with applicable law and stock exchange rules, for so long as Energy Capital Partners and its affiliates beneficially own at least 30% of our common stock then outstanding, it shall be entitled to designate a number of directors equal to one fewer than a majority of the directors; for so long as Energy Capital Partners and its affiliates beneficially own at least 20% of our common stock then outstanding, it shall be entitled to designate the greater of three directors and 25% of the total number of directors (rounded up to the next whole number); and for so long as Energy Capital Partners and its affiliates beneficially own at least 10% of our common stock then outstanding, it shall be entitled to designate the greater of two directors and 15% of the total number of directors (rounded up to the next whole number); and for so long as Energy Capital Partners and its affiliates beneficially own at least 5% of our common stock then outstanding, it shall be entitled to designate one director.

Energy Capital Partners is entitled to designate the replacement for any of its board designees whose board service terminates prior to the end of the director's term regardless of their beneficial ownership at such time. Energy Capital Partners also has the right, but not the obligation, to designate at least one of its nominees as a member to each of the committees of our board of directors for so long as it has the right to designate at least one director, subject to compliance with applicable law and stock exchange rules.

Additionally, for as long as Energy Capital Partners and its affiliates hold at least 10% of our outstanding common stock, any directors designated by Energy Capital Partners will have certain information and access rights to our management, including the right to receive our annual budget, business plan and financial forecasts.

The stockholders agreement will terminate upon the earliest to occur of (a) the dissolution of the Company, (b) the date on which Energy Capital Partners and its affiliates cease to own any outstanding shares of our common stock and (c) the written agreement of the company and Energy Capital Partners.

COMMAND=STYLE_ADDED,"margin-left:10.0pt;text-indent:-10.0pt;" Anti-Takeover Effects of Provisions of Our Certificate of Incorporation, our Bylaws and our Stockholders Agreement

Some provisions of the DGCL our certificate of incorporation, our bylaws and our stockholders agreement 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 directors. These provisions may also have the effect of preventing changes in our management. It is possible that these

ZEQ.=2,SEQ=12,EFW="2235207",CP="PROPETRO HOLDING CORP.",DN="1",CHK=648255,FOLIO='9',FILE='DISK103:[18ZBC1.18ZBC48101]DE48101A.;6',USER='CHE107203',CD=';3-MAY-2018;10:07'

Table of Contents

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.

COMMAND=STYLE_ADDED,"margin-left:10.0pt;text-indent:-10.0pt;" Anti-Takeover Effects of Delaware Law

Section 203 of the DGCL prohibits a Delaware corporation, including those whose securities are listed for trading on the NYSE, from engaging in any business combination (as defined in Section 203) with any interested stockholder (as defined in Section 203) for a period of three years following the date that the stockholder became an interested stockholder, unless:

A corporation may elect not to be subject to Section 203 of the DGCL. We have elected to not be subject to the provisions of Section 203 of the DGCL.

(1) Pursuant to Rules 456(b) and 457(r) under the Securities Act of 1933, as amended, the SEC registration fee will be paid at the time of any particular offering of securities under the registration statement, and is therefore not currently determinable. (2) These fees are calculated based on the securities offered and the number of issuances and accordingly cannot be estimated at this time.

Item 15. Indemnification of Directors and Officers

We are a Delaware corporation. Our certificate of incorporation provides that a director will not be liable to the corporation or its stockholders for monetary damages to the fullest extent permitted by the Delaware General Corporation Law (the "DGCL"). In addition, if the DGCL is amended to authorize the further elimination or limitation of the liability of directors, then the liability of a director of the corporation, in addition to the limitation on personal liability provided for in our certificate of incorporation, will be limited to the fullest extent permitted by the amended DGCL. Our bylaws provide that the corporation will indemnify, and advance expenses to, any officer or director to the fullest extent authorized by the DGCL.

Section 145 of the DGCL provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement in connection with specified actions, suits and proceedings whether civil, criminal, administrative, or investigative, other than a derivative action by or in the right of the corporation, 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 and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. A similar standard is applicable in the case of derivative actions, 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. The statute provides that it is not exclusive of other indemnification that may be granted by a corporation's certificate of incorporation, bylaws, disinterested director vote, stockholder vote, agreement or otherwise.

Our certificate of incorporation also contains indemnification rights for our directors and our officers. Specifically, our certificate of incorporation provides that we shall indemnify our officers and directors to the fullest extent authorized by the DGCL. Further, we may maintain insurance on behalf

of our officers and directors against expense, liability or loss asserted incurred by them in their capacities as officers and directors. We have obtained directors' and officers' insurance to cover our directors, officers and some of our employees for certain liabilities.

We have entered into written indemnification agreements with our directors and executive officers. Under these proposed agreements, if an officer or director makes a claim of indemnification to us, either a majority of the independent directors or independent legal counsel selected by the independent directors must review the relevant facts and make a determination whether the officer or director has met the standards of conduct under Delaware law that would permit (under Delaware law) and require (under the indemnification agreement) us to indemnify the officer or director.

Any underwriting agreement or distribution agreement that the registrant enters into with any underwriters or agents involved in the offering or sale of any securities registered hereby may require such underwriters or dealers to indemnify the registrant, some or all of its directors and officers and its controlling persons, if any, for specified liabilities, which may include liabilities under the Securities Act of 1933, as amended.

Table of Contents

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:

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, 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.

(h) Insofar as indemnification for liabilities arising under the Securities Act of 1933 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 Securities and Exchange Commission 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.
