ABOUT THIS PROSPECTUS SUPPLEMENT

This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of this offering and also adds to and updates information contained in the accompanying base prospectus and the documents incorporated by reference in this prospectus supplement and the accompanying base prospectus. The second part is the accompanying base prospectus, which, among other things, gives more general information, some of which may not apply to this offering.

We expect delivery of the shares of Class A Common Stock will be made against payment therefor on or about February 11, 2021, which is the third business day following the date of pricing of the shares (such settlement being referred to as “T+3”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the shares of Class A Common Stock more than two business days prior to the scheduled settlement date will be required, by virtue of the fact that the shares initially will settle in T+3, to specify an alternative settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the shares of Class A Common Stock who wish to trade the shares prior to their date of delivery hereunder should consult their own advisors.

Except as otherwise indicated or required by the context, all references in this prospectus supplement to the “Company,” “we,” “us” or “our” refer to Liberty Oilfield Services Inc. and its consolidated subsidiaries.

You should rely only on the information contained or incorporated by reference in this prospectus supplement, the accompanying base prospectus or any “free writing prospectus” we may authorize to be delivered to you. Neither we nor the underwriter has authorized anyone to provide you with additional or different information. If anyone provides you with different or inconsistent information, you should not rely on it. This prospectus supplement is not an offer to sell or a solicitation of an offer to buy our Class A Common Stock in any jurisdiction where such offer or any sale would be unlawful. You should not assume that the information contained in this prospectus supplement, the accompanying base prospectus or any free writing prospectus is accurate as of any date other than the dates shown in these documents or any information that we have incorporated by reference is accurate as of any date other than the date of such information.

S-2

RISK FACTORS

The shares of our Class A Common Stock offered by this prospectus supplement and the accompanying base prospectus involve a high degree of risk. You should read carefully the risks and uncertainties described in this prospectus supplement, the accompanying base prospectus and the documents incorporated by reference herein, including the discussion of the material risks relating to an investment in our Class A Common Stock beginning on page 3 of the accompanying base prospectus, as well as those discussed under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019 and Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2020, June 30, 2020 and September 30, 2020.

Risks Relating to OneStim’s Business

The sand mining operations are subject to a number of risks relating to the proppant industry.

In connection with the OneStim Acquisition, we acquired two state-of-the-art sand mines in the Permian Basin. Sand mining operations are subject to risks normally encountered in the proppant industry. These risks include, among others:

• inability to obtain necessary production equipment or replacement parts;

• natural disasters or inclement or hazardous weather conditions, including, but not limited to, cold weather, flooding, tornadoes and the physical impacts of climate change;

• unanticipated ground, grade or water conditions;

• inability to acquire or maintain, or public or nongovernmental organization opposition to, necessary permits for mining, access or water rights;

• our ability to timely obtain necessary authorizations, approvals and permits from regulatory agencies (including environmental agencies, such as the U.S. Fish and Wildlife Service agency (“USFWS”), where our operations in West Texas may be slowed, limited or halted due to conservation efforts targeted at the habitat of the dunes sagebrush lizard) on terms acceptable to us;

• labor disputes;

• technical difficulties or failures;

• pit wall or pond failures, and sluffing events;

• environmental hazards and costs associated with environmental compliance or as a result of unauthorized releases into the environment;

• restrictions imposed on our operations related to the protection of natural resources, including plant and animal species;

• industrial accidents;

• reduction in the amount of water available for processing;

• changes in the price and availability of natural gas, diesel fuel or electricity that we use as fuel sources at our frac sand facilities;

• fires, explosions, chemical mishandling or other accidents;

• facility suspensions or shutdowns in response to environmental regulatory actions; and

• on-site or off-site trucking accidents or other disruption to trucking service.

Any of these risks could result in damage to, or destruction of, the mining properties or frac sand facilities, personal injury, loss of life, environmental contamination or damage, delays, limitations or cancellations in

S-3

mining or processing activities, losses or possible legal liability. Any prolonged downtime or shutdowns at the mining properties or frac sand facilities could have a material adverse effect on our business, financial condition and results of operations.

Silica-related legislation, health issues and litigation could have a material adverse effect on our business, reputation or results of operations.

We are subject to laws and regulations relating to human exposure to crystalline silica. Historically, our environmental compliance costs with respect to existing crystalline silica requirements have not had a material adverse effect on our results of operations; however, federal regulatory authorities and analogous state agencies may continue to propose changes in their regulations regarding workplace exposure to crystalline silica, such as permissible exposure limits and required controls and personal protective equipment. We may not be able to comply with any new laws and regulations that are adopted, and any new laws and regulations could have a material adverse effect on our operating results by requiring us to modify or cease our operations.

In addition, the inhalation of respirable crystalline silica is associated with the lung disease silicosis. There is evidence of an association between crystalline silica exposure or silicosis and lung cancer and a possible association with other diseases, including immune system disorders such as scleroderma. These health risks have been, and may continue to be, a significant issue confronting the hydraulic fracturing industry. Concerns over silicosis and other potential adverse health effects, as well as concerns regarding potential liability from the use of hydraulic fracture sand, may have the effect of discouraging our customers’ use of our hydraulic fracture sand. The actual or perceived health risks of handling hydraulic fracture sand could materially and adversely affect hydraulic fracturing service providers, including us, through reduced use of hydraulic fracture sand, the threat of product liability or employee lawsuits, increased scrutiny by federal, state and local regulatory authorities of us and our customers or reduced financing sources available to the hydraulic fracturing industry. Furthermore, we may incur additional costs with respect to purchasing specialized equipment designed to reduce exposure to crystalline silica in connection with our operations or invest capital in new equipment.

The occurrence of explosive incidents could disrupt our operations and could adversely affect our business, financial condition and results of operations.

The wireline service we provide to oil and natural gas exploration and production (“E&P”) customers involve the storage and handling of explosive materials. Despite the use of specialized facilities to store explosive materials and intensive employee training programs, the handling of explosive materials could result in incidents that temporarily shut down or otherwise disrupt our or E&P customers’ operations or could cause restrictions, delays or cancellations in the delivery of services. It is possible that an explosion could result in death or significant injuries to employees and other persons. Material property damage to us, E&P customers and third parties could also occur. Any explosive incident could expose us to adverse publicity or liability for damages or cause production restrictions, delays or cancellations, any of which developments could have a material adverse effect on our ability to compete, business, financial condition and results of operations.

We are subject to the Federal Mine Safety and Health Act of 1977, which imposes stringent health and safety standards on numerous aspects of its operations.

Our operations are subject to the Federal Mine Safety and Health Act of 1977, as amended by the Mine Improvement and New Emergency Response Act of 2006, which imposes stringent health and safety standards on numerous aspects of mineral extraction and processing operations, including the training of personnel, operating procedures, operating equipment, and other matters. Our failure to comply with such standards, or changes in such standards or the re-interpretation or more stringent enforcement thereof, could have a material adverse effect on our business and financial condition or otherwise impose significant restrictions on its ability to conduct mineral extraction and processing operations.

S-4

Following the OneStim Acquisition, we expanded our operations to Canada and may be subject to increased business and economic risks that could harm our business.

The Company has historically owned and operated its assets exclusively within the United States. In connection with the OneStim Acquisition, we acquired certain Canadian assets and liabilities, which not only marked our entry into Canada as a new geographical territory, but an international market where we have limited or no experience in owning and operating assets and providing our services. If we fail to manage our operations in Canada successfully, our business may suffer. We are subject to a variety of risks inherent in doing business internationally, including:

• risks related to the legal and regulatory environment in foreign jurisdictions and unexpected changes in laws, regulatory requirements and enforcement;

• fluctuations in currency exchange rates;

• complying with multiple tax jurisdictions;

• difficulties in staffing and managing international operations and the increased travel, infrastructure and compliance costs associated with international locations and employees;

• regulations that might add difficulties in repatriating cash earned outside the United States and otherwise preventing us from freely moving cash;

• complying with statutory equity requirements; and

• complying with the U.S. Foreign Corrupt Practices Act and similar laws in Canada.

If we are unable to manage the complexity of our international operations successfully, our business could be seriously harmed.

Our operations in Canada could subject us to currency translation risk, which could cause our results of operations and financial condition to fluctuate significantly from period to period.

A portion of our revenue may be derived from our activities and operations in Canada. Because we translate the results of operations and financial condition of its Canadian operations into U.S. dollars, our reported results of operations and financial condition are subject to changes in the exchange rate between the two currencies. Fluctuations in foreign currency exchange rates could affect our revenue, expenses and operating margins, and if we decide to further expand our international operations, we will become more exposed to the effects of fluctuations in currency exchange rates. Currently, we do not hedge our exposure to changes in foreign exchange rates.

Risks Related to the TRAs

The Company is required to make payments under the TRAs for certain tax benefits that it may claim, and the amounts of such payments could be significant.

In connection with the Company’s initial public offering (the “IPO”), on January 17, 2018, the Company entered into two Tax Receivable Agreements (the “TRAs”) with R/C Energy IV Direct Partnership, L.P. and the then-existing owners of Liberty Oilfield Services Holdings LLC that continued to own units in Liberty Oilfield Services New HoldCo LLC (the “Legacy Owners” and each such person and any permitted transferee, a “TRA Holder”). The TRAs generally provide for the payment by the Company to each TRA Holder of 85% of the net cash savings, if any, in U.S. federal, state and local income tax and franchise tax (computed using simplifying assumptions to address the impact of state and local taxes) that the Company actually realizes (or is deemed to realize in certain circumstances) as a result of certain increases in tax basis, net operating losses available to the Company as a result of the corporate reorganization performed in connection with the IPO, and certain benefits attributable to imputed interest. The Company will retain the benefit of the remaining 15% of these cash savings.

S-5

The Company is a holding company and has no material assets other than its equity interest in Liberty LLC. Because the Company has no independent means of generating revenue, its ability to make payments under the TRAs is dependent on the ability of Liberty LLC to make distributions to the Company in an amount sufficient to cover its obligations under the TRAs. To the extent that the Company is unable to make payments under the TRAs for any reason, such payments will be deferred and will accrue interest until paid.

The term of each of the TRAs continues until all tax benefits that are subject to such TRAs have been utilized or expired, unless the Company experiences a change of control (as defined in the TRAs, which includes certain mergers, asset sales and other forms of business combinations) or the TRAs are terminated early (at the Company’s election or as a result of its breach), and the Company makes the termination payments specified in such TRAs. In addition, payments the Company makes under the TRAs will be increased by any interest earned from the due date (without extensions) of the corresponding tax return. Payments under the TRAs commenced in 2020 and so long as the TRAs are not terminated, are anticipated to continue for 15 years after the date of the last redemption of the units of Liberty LLC.

In certain cases, if the Company experiences a change of control (as defined under the TRAs, which includes certain mergers, asset sales and other forms of business combinations) or the TRAs terminate early (at the Company’s election or as a result of its breach), the Company would be required to make a substantial, immediate lump-sum payment, and such payment may be significantly in advance of, and may materially exceed, the actual realization, if any, of the future tax benefits to which the payment relates. As a result, the Company’s obligations under the TRAs could have a substantial negative impact on its liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales, or other forms of business combinations or changes of control. There can be no assurance that we will be able to finance our obligations under the TRAs. Furthermore, as a result of this payment obligation, holders of our Class A Common Stock could receive substantially less consideration in connection with a change of control transaction than they would receive in the absence of such obligation. Since our payment obligations under the TRAs will not be conditioned upon the TRA Holders’ having a continued interest in the Company or Liberty LLC, the TRA Holders’ interests may conflict with those of the holders of our Class A Common Stock.

Payments under the TRAs are based on the tax reporting positions that we will determine. The TRA Holders will not reimburse us for any payments previously made under the TRAs if any tax benefits that have given rise to payments under the TRAs are subsequently disallowed, except that excess payments made to any TRA Holder will be netted against payments that would otherwise be made to such TRA Holder, if any, after our determination of such excess. As a result, in such circumstances, the Company could make payments that are greater than its actual cash tax savings, if any, and may not be able to recoup those payments, which could adversely affect the Company’s liquidity. Furthermore, the payments under the TRAs will not be conditioned upon a holder of rights under each of the TRAs having a continued ownership interest in the Company or Liberty LLC.

Risks Related to Legal Matters and Regulation

The federal Endangered Species Act (“ESA”) and Migratory Bird Treaty Act (“MBTA”) and other restrictions intended to protect certain species of wildlife govern our and our customers’ operations and additional restrictions may be imposed in the future, which constraints could have an adverse impact on operations.

Our mining operations and the oil and natural gas operations of our customers could be adversely affected by seasonal or permanent restrictions on drilling activities designed to protect various wildlife and their habitats, which may limit our ability to operate in protected areas or areas that may become protected in the future. Permanent restrictions imposed to protect endangered species could prohibit drilling in certain areas or require the implementation of expensive mitigation measures.

The ESA restricts activities that may result in a “take” of endangered or threatened species and provides for substantial penalties in cases where listed species are taken by being harmed. Harm under the ESA includes

S-6

acts that actually kill or injure wildlife as well as significant habitat modification or degradation that significantly impairs essential behavioral patterns, including breeding, feeding or sheltering. Take prohibitions also protect migratory birds under the MBTA.

The dunes sagebrush lizard is one example of a species that, if listed as endangered or threatened under the ESA, could impact our operations and the operations of our customers. The dunes sagebrush lizard is found in the active and semi-stable shinnery oak dunes of southeastern New Mexico and adjacent portions of Texas, including areas where our customers operate and our frac sand facilities are located. The USFWS is currently reviewing a petition from the Center for Biological Diversity and the Defenders of Wildlife to list the dunes sagebrush lizard as endangered or threatened under the ESA, and on July 16, 2020, issued a 90-day finding that the petition presents substantial information that listing may be warranted and the agency will conduct a more thorough review to determine whether listing may be warranted. If the dunes sagebrush lizard is listed as an endangered or threatened species, our operations and the operations of our customers in any area that is designated as the dunes sagebrush lizard’s habitat may be limited, delayed or, in some circumstances, prohibited, and we and our customers could be required to comply with expensive mitigation measures intended to protect the dunes sagebrush lizard and its habitat.

The USFWS has approved several Enhancement of Survival Permits that allow operations in designated habitats to continue if the dunes sagebrush lizard is listed provided that qualification criteria and conservation measures required by such permits are met. One such permit is referred to as the Texas Conservation Plan (“TCP”). The TCP was developed as a voluntary conservation plan for the dunes sagebrush lizard by the Texas Comptroller, which served as the permit holder until the transfer of the TCP to a new permit holder in October 2020. The USFWS issued a second permit, a Candidate Conservation Agreement with Assurances (“CCAA”), for operations in Texas that may affect the dunes sagebrush lizard in January 2021. The permits cover incidental “take” of the dunes sagebrush lizard associated with oil and gas exploration and development, sand mining, renewable energy development and operations, pipeline construction and operations, local government activities, agricultural activities, and general construction activities within the CCAA permit area that could affect suitable habitat. Enrollment in either permit by us our any of our customers could result in new or more stringent conservation measures or land, water, or resource use restrictions beyond the measures and restrictions that we or our customers are currently required to comply with. Moreover, the Biden Administration may want to further review or reconsider these actions. The issuance of more stringent conservation measures or land, water, or resource use restrictions could result in operational delays and decreased production and revenue for us as well as our customers.

Furthermore, to the extent species are listed under the ESA or similar state laws, or are protected under the MBTA, or previously unprotected species are designated as threatened or endangered in areas where we or our customers operate, we could experience increased costs arising from species protection measures and delays or limitations in our or our customers’ performance of operations, which could adversely affect or reduce demand for our frac sand.

Federal, state and local legislative and regulatory initiatives relating to hydraulic fracturing as well as governmental reviews and investment practices for such activities may serve to limit future oil and natural gas exploration and production activities and could have a material adverse effect on our results of operations and business.

Currently, hydraulic fracturing is generally exempt from federal regulation under the Safe Drinking Water Act Underground Injection Control (the “SDWA UIC”) program and is typically regulated by state oil and gas commissions or similar state agencies but the practice continues to attract considerable public, scientific and governmental attention in certain parts of the country, resulting in increased scrutiny and regulation, including by federal agencies who have conducted investigations or asserted regulatory authority over certain aspects of the process. For example, in late 2016, the Environmental Protection Agency (the “EPA”) released its final report on the potential impacts of hydraulic fracturing on drinking water resources, concluding that “water cycle” activities

S-7

associated with hydraulic fracturing may impact drinking water resources under certain circumstances. Additionally, the EPA has asserted regulatory authority pursuant to the SDWA UIC program over hydraulic fracturing activities involving the use of diesel fuel in the fracturing fluid and issued guidance covering such activities, and has published an Advance Notice of Proposed Rulemaking regarding Toxic Substances Control Act reporting of the chemical substances and mixtures used in hydraulic fracturing. Moreover, in 2016, the EPA published an effluent limitation guideline final rule prohibiting the discharge of produced water from onshore unconventional oil and natural gas extraction facilities to publicly owned wastewater treatment plants. In addition, the U.S. Bureau of Land Management (the “BLM”) under the Obama Administration published a final rule in 2015 that established new or more stringent standards relating to hydraulic fracturing on federal and Native American lands, but the BLM rescinded the 2015 rule in late 2017 and that agency decision to rescind the rule was upheld by a federal trial court in March 2020. That rescission is currently on appeal to the U.S. Court of Appeals for the Ninth Circuit. The BLM under the Obama Administration also adopted a rule in 2016 addressing the loss of natural gas from oil and gas operations through venting, flaring and leaks but the BLM under the Trump Administration published a final rule rescinding the 2016 final rule in late 2018. Since that time, litigation challenging the BLM’s 2016 final rule and the 2018 final rule has resulted in rescission in federal courts of both the 2016 rule and the 2018 final rule but appeals of one or both of those decisions are expected.

The EPA has likewise adopted rules on the capture of methane and VOC emissions released during oil and natural gas activities, including hydraulic fracturing. In recent years, those rules have been the subject of ongoing legal challenges. In 2016, the EPA under the Obama Administration published a final rule under the Clean Air Act establishing performance standards for those emissions but since that time the EPA under the Trump Administration has taken several steps to delay implementation of the rule, including issuance of a final rule in September 2020 that amended the 2016 rule by removing the transmission and storage segments from the scope of the rule, rescinding the VOC and methane emissions standards for those segments, and rescinding methane emissions standards for the production and processing segments. Those amendments were immediately challenged in separate lawsuits brought by states and environmental organizations, which have been consolidated in the U.S. Court of Appeals for the D.C. Circuit. Notwithstanding these legal challenges, President Biden issued an executive order on January 20, 2021 that, among other things, called for issuance of proposed rules by no later than September 2021 that would restore Obama-era rules for methane standards applicable to new, modified, and reconstructed sources by suspending, revising or rescinding the EPA’s September 2020 final rule and establish new methane and volatile organic compound standards applicable to existing oil and gas operations, including the production, transmission, processing and storage segments.

In addition to federal regulatory actions, from time to time legislation has been introduced, but not enacted, in Congress to provide for federal regulation of hydraulic fracturing and to require disclosure of the chemicals used in the hydraulic fracturing process. It is unclear whether legislation will be introduced in the new 117^th Congress that commenced in January 2021, whether as part of legislation to address climate change or otherwise, that seeks to restrict or impose conditions on hydraulic fracturing activities and what the prospects would be for any such legislation in light of the makeup of the 117^th Congress.

It remains to be seen how the incoming Biden Administration will address hydraulic fracturing and broader issues related to oil and gas development. The new Administration is expected to place significant emphasis on steps to address climate change. Although the U.S. had withdrawn on November 4, 2020 from the non-binding Paris Agreement, which requested that nations limit their greenhouse gas emissions through individually-determined reduction goals every five years after 2020 Paris Agreement, President Biden issued an executive order on January 20, 2021 recommitting the United States to the Paris Agreement. With the United States recommitting to the Paris Agreement, executive orders may be issued or federal legislation or regulatory initiatives may be adopted to achieve the agreement’s goals, which could include additional restrictions on hydraulic fracturing or related oil and gas development activities. Additionally, on January 20, 2021, the Acting Secretary of the U.S. Department of the Interior issued an order, effective immediately, that effectively suspends new oil and gas leases and drilling permits on non-Indian federal lands and waters for a period of 60 days, but the suspension does not limit existing operations under valid leases. On January 27, 2021, President Biden issued an

S-8

executive order that, among other things, ordered the Secretary of the Interior to pause, to the extent consistent with applicable law, the issuance of new oil and gas leases on federal public lands and offshore waters pending completion of a comprehensive review and reconsideration of federal oil and gas permitting and leasing practices that take into consideration potential climate and other impacts associated with oil and gas activities on such lands and waters. Existing leases are unaffected by this order and a White House fact sheet indicates that the order will not directly affect Indian lands held by the U.S. in trust for Tribes. This January 27, 2021 order further directs applicable agencies to identify fossil fuel subsidies provided by their respective agencies and subsequently take measures to ensure, to the extent consistent with applicable law, that federal funding is not directly subsidizing fossil fuels, with a further objective of eliminating fossil fuel subsidies from federal budget requests beginning in federal Fiscal Year 2022. In response, one industry group has already challenged the order in a federal court in Wyoming for “indefinitely suspending the federal oil and gas leasing program.” To the extent that our operations or the operations of our customers in certain areas of the U.S. are restricted, delayed for varying lengths of time or cancelled, such developments may significantly reduce demand for our services and have a material adverse effect on our results of operations and financial condition. It remains to be seen whether or to what extent the Biden Administration will pursue legislation, additional executive actions, regulations or other regulatory initiatives to limit, delay or prohibit hydraulic fracturing or other aspects of oil and gas development including, for example, by seeking to reinstate some of the regulations that were rescinded under the Trump Administration. In the event that new federal restrictions, delays or prohibitions relating to the hydraulic fracturing process are adopted in areas where we or our customers conduct business, we or our customers may incur additional costs or permitting requirements to comply with such federal requirements that may be significant and, in the case of our customers, also could result in added restrictions, delays or curtailments in the pursuit of exploration, development, or production activities, which would in turn reduce the demand for our services.

Moreover, many states and local governments have adopted, and other governmental entities may in the future adopt, regulations that impose more stringent permitting, disclosure and well-construction requirements on hydraulic fracturing operations, including states where we or our customers operate. Texas, Colorado and North Dakota, among other states, have adopted regulations that impose new or more stringent permitting, disclosure, disposal, and well construction requirements on hydraulic fracturing operations. States could also elect to place prohibitions on hydraulic fracturing, as several states have already done.

In addition, some states have adopted broader sets of requirements related to oil and gas development more generally that could impact hydraulic fracturing activities. For example, in 2019 the Colorado legislature adopted SB 19-181, which amended the mandate of the Colorado Oil and Gas Conservation Commission to place greater emphasis on protection of human health and the environment while also giving greater regulatory authority to local jurisdictions. The COGCC has now modified its rules for oil and gas production in many respects to address the requirements of the legislation, adopting among other things increased setback requirements and provisions for assessing alternative sites for well pads to minimize environmental impacts. Local land use restrictions, such as city ordinances, may also restrict drilling in general and/or hydraulic fracturing in particular. Environmental groups, local citizens groups and others continue to seek to use a variety of means – such as the ballot initiative process in Colorado – to force action on additional restrictions on hydraulic fracturing and oil and gas development generally.

A theme of avoiding or limiting investment in companies that engage in hydraulic fracturing has entered into capital markets. For example, in July 2020, Deutsche Bank announced that it would no longer finance oil and gas projects that use hydraulic fracturing in countries with scarce water supplies. Moreover, BlackRock, one of the largest asset managers in the world, recently affirmed its commitment to divest from investments in fossil fuels due to concerns over climate change. While a substantial number of major banks and financing sources remain active in investments related to hydraulic fracturing, the investment avoidance or limitation theme could expand in the future and restrict access to capital for companies like us.

Increased regulation and attention given to the hydraulic fracturing process could lead to greater opposition to, and litigation concerning, oil and natural gas production activities using hydraulic fracturing techniques.

S-9

Additional legislation or regulation could also lead to operational delays for our customers or increased operating costs in the production of oil and natural gas, including from the developing shale plays, or could make it more difficult for us and our customers to perform hydraulic fracturing. The adoption of any additional laws or regulations regarding hydraulic fracturing or a furtherance of themes of investment avoidance or limitation in hydraulic fracturing could potentially cause a decrease in the completion of new oil and natural gas wells and an associated decrease in demand for our services and increased compliance costs and time. Such a decrease could have a material adverse effect on our liquidity, consolidated results of operations, and consolidated financial condition. Moreover, the increased competitiveness of alternative energy sources (such as wind, solar, geothermal, tidal and biofuels) or increased focus on reducing the use of combustion engines in transportation (such as governmental mandates that ban the sale of new gasoline-powered automobiles) could reduce demand for hydrocarbons and therefore for our services, which would lead to a reduction in our revenues.

S-15

The lock-up restrictions described in the foregoing do not apply to the selling stockholders with respect to:

• transactions relating to shares of Class A Common Stock or securities convertible into or exercisable or exchangeable for Class A Common Stock being sold, cancelled or transferred pursuant to the transactions contemplated by the underwriting agreement in connection with this offering;

• transactions relating to shares of Class A Common Stock or other securities acquired in open market transactions after the completion of this offering;

• the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Class A Common Stock, provided that (i) such plan does not provide for the transfer of Class A Common Stock during the restricted period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the holder or the Company regarding the establishment of such plan, such announcement or filing will include a statement to the effect that no transfer of Class A Common Stock may be made under such plan during the restricted period;

• transfers to the Company of shares of Class A Common Stock or any security convertible into or exercisable for Class A Common Stock in connection with agreements that provide the Company with a right of first refusal with respect to transfers of such shares or securities;

• sales of the holder’s securities made pursuant to a trading plan adopted pursuant to Rule 10b5-1 under the Exchange Act prior to the date of the lock-up agreement, provided that any filing under Section 16(a) of the Exchange Act that is made in connection with any such sales during the restricted period will state that such sales have been executed under a trading plan pursuant to Rule 10b5-1 under the Exchange Act will also state the date such trading plan was adopted;

provided that, with respect to the preceding bullets, (i) the restrictions do not apply to the shares of Class A Common Stock issued upon such exercise, conversion or settlement, and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of shares of Class A Common Stock, will be required or will be voluntarily made during the restricted period (other than a Form 5 made when required or to the extent any such filing under Section 16(a) of the Exchange Act indicates that such transfer or distribution did not involve a disposition for value).

The lock-up restrictions described in the foregoing do not apply to us with respect to:

• the sale of shares to the underwriter;

• the issuance by us of shares of Class A Common Stock upon the exercise of an option or a warrant or the conversion of a security outstanding on the date of this prospectus supplement of which the underwriter has been advised in writing; or

The underwriter, in its sole discretion, may release the shares and other securities subject to the lock-up agreements described above in whole or in part at any time with or without notice.

In connection with the OneStim Acquisition, Schlumberger agreed to certain restrictions on transfers of the Company’s Common Stock. Pursuant to the underwriting agreement, the Company has agreed that it will not, without written consent of the underwriter, waive such restrictions during the restricted period.

In order to facilitate the offering of the shares, the underwriter may engage in transactions that stabilize, maintain or otherwise affect the price of the shares. Specifically, the underwriter may sell more shares than they are obligated to purchase under the underwriting agreement, creating a naked short position. The underwriter must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriter is 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 this offering. As an

S-16

additional means of facilitating this offering, the underwriter may bid for, and purchase, shares in the open market to stabilize the price of the shares. These activities may raise or maintain the market price of the shares above independent market levels or prevent or retard a decline in the market price of the shares. The underwriter is not required to engage in these activities and may end any of these activities at any time.

We and the selling stockholders have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act.

A prospectus supplement in electronic format may be made available on websites maintained by the underwriter, or selling group members, if any, participating in this offering. The underwriter may agree to allocate a number of shares to its online brokerage account holders. Any such Internet distributions will be allocated on the same basis by the underwriter as other allocations.

The underwriter and its affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. The underwriter and its affiliates have, from time to time, performed, and may in the future perform, various financial advisory, investment banking, commercial banking and other services for us and our affiliates, for which they received or will receive customary fees and expenses.

Furthermore, the underwriter and certain of its affiliates may, from time to time, enter into arms-length transactions with us in the ordinary course of their business. In the ordinary course of their various business activities, the underwriter and its affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities or instruments of the company. The underwriter and its affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

DESCRIPTION OF CAPITAL STOCK

Our authorized capital stock consists of 400,000,000 shares of Class A common stock, $0.01 par value per share, 400,000,000 shares of Class B common stock, $0.01 par value per share, and 10,000 shares of preferred stock, $0.01 par value per share.

There are 68,962,200 shares of Class A common stock, 43,570,372 shares of Class B common stock and no shares of preferred stock issued and outstanding as of July 5, 2019.

The following summary of the capital stock and amended and restated certificate of incorporation and bylaws of Liberty Inc. 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 bylaws, which are filed as exhibits to the registration statement of which this prospectus is a part.

Class A Common Stock

Voting Rights. Holders of shares of our Class A common stock are entitled to one vote per share held of record on all matters to be voted upon by the stockholders. The holders of Class A common stock do not have cumulative voting rights in the election of directors.

Dividend Rights. Holders of shares of our Class A common stock are entitled to ratably receive dividends when and if declared by our board of directors out of funds legally available for that purpose, subject to any statutory or contractual restrictions on the payment of dividends and to any prior rights and preferences that may be applicable to any outstanding preferred stock.

Liquidation Rights. Upon our liquidation, dissolution, distribution of assets or other winding up, the holders of Class A common stock are entitled to receive ratably the assets available for distribution to the stockholders after payment of liabilities and the liquidation preference of any of our outstanding shares of preferred stock.

Other Matters. The shares of Class A common stock have no preemptive or conversion rights and are not subject to further calls or assessment by us. There are no redemption or sinking fund provisions applicable to the Class A common stock. All outstanding shares of our Class A common stock are fully paid and non-assessable.

Class B Common Stock

Generally. The Liberty Unit Holders own one share of Class B common stock for each Liberty LLC Unit that they hold. Accordingly, the Liberty Unit Holders have a number of votes in Liberty Inc. equal to the aggregate number of Liberty LLC Units that they hold.

Voting Rights. Holders of shares of our Class B common stock are entitled to one vote per share held of record on all matters to be voted upon by the stockholders. Holders of shares of our Class A common stock and Class B common stock vote together as a single class on all matters presented to our stockholders for their vote or approval, except with respect to the amendment of certain provisions of our amended and restated certificate of incorporation that would alter or change the powers, preferences or special rights of the Class B common stock so as to affect them adversely, which amendments must be by a majority of the votes entitled to be cast by the holders of the shares affected by the amendment, voting as a separate class, or as otherwise required by applicable law.

Dividend and Liquidation Rights. Holders of our Class B common stock do not have any right to receive dividends, unless the dividend consists of shares of our Class B common stock or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class B common stock paid proportionally with respect to each outstanding share of our Class B common stock and a dividend consisting of

7

shares of Class A common stock or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class A common stock on the same terms is simultaneously paid to the holders of Class A common stock. Holders of our Class B common stock do not have any right to receive a distribution upon a liquidation or winding up of Liberty Inc.

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 10,000 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 the 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 will not be entitled to vote at or receive notice of any meeting of stockholders.

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

Some provisions of Delaware law, and our amended and restated certificate of incorporation and our amended and restated bylaws described below, 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, summarized below, 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

We are not subject to the provisions of Section 203 of the Delaware General Corporation Law (the “DGCL”), regulating corporate takeovers. In general, those provisions prohibit a Delaware corporation, including those whose securities are listed for trading on the NYSE, 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.

Amended and Restated Certificate of Incorporation and 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 Class A common stock.

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 the board of directors, subject to the rights of the holders of any series of our preferred stock to elect directors under specified circumstances;

• 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, after we cease to be a controlled company, 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, after we cease to be a controlled company, our amended and restated certificate of incorporation and amended and restated bylaws may be amended by the affirmative vote of the holders of at least 66 ²/₃% of our then outstanding Class A common stock;

• provide that, after we cease to be a controlled company, special meetings of our stockholders may only be called by the board of directors, the chief executive officer or the chairman of the board;

• provide, after we cease to be a controlled company, 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, R/C IV Liberty Holdings, L.P. and R/C Energy IV Direct Partnership, L.P. and that they have no obligation to offer us those investments or opportunities; and

• provide that our amended and restated bylaws can be amended by the board of directors.

Forum Selection

Our amended and restated certificate of incorporation provide 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 or any director or officer or other employee of ours 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 or any director or officer or other employee of ours 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 provide 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 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.

Limitation 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. 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 also entered into indemnification agreements with each of our current directors and officers and intend to enter into indemnification agreements with any future directors and officers. These agreements require us to

10

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 that is in our amended and restated certificate of incorporation and the indemnification agreements will facilitate our ability to continue to attract and retain qualified individuals to serve as directors and officers.

Registration Rights

In connection with the closing of our IPO, we entered into a registration rights agreement. The agreement contains provisions by which we agreed to register under the federal securities laws the offer and resale of shares of our Class A common stock by the parties to the Registration Rights Agreement. These registration rights are subject to certain conditions and limitations. We are generally be obligated to pay all registration expenses in connection with these registration obligations, regardless of whether a registration statement is filed or becomes effective.

Transfer Agent and Registrar

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

Listing

Our Class A common stock is listed on the NYSE under the symbol “LBRT.”

CERTAIN ERISA CONSIDERATIONS

The following is a summary of certain considerations associated with the purchase and holding of shares of our Class A common stock by employee benefit plans that are subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”) or employee benefit plans that are governmental plans (as defined in Section 3(32) of ERISA), certain church plans (as defined in Section 3(33) of ERISA), non-U.S. plans (as described in Section 4(b)(4) of ERISA) or other plans that are not subject to the foregoing but may be subject to provisions under any other federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code (collectively, “Similar Laws”), and entities whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement (each, a “Plan”).

This summary is based on the provisions of ERISA and the Code (and related regulations and administrative and judicial interpretations) as of the date of this prospectus. This summary does not purport to be complete, and no assurance can be given that future legislation, court decisions, regulations, rulings or pronouncements will not significantly modify the requirements summarized below. Any of these changes may be retroactive and may thereby apply to transactions entered into prior to the date of their enactment or release. This discussion is general in nature and is not intended to be all inclusive, nor should it be construed as investment or legal advice.

General Fiduciary Matters

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (an “ERISA Plan”) and prohibit certain transactions involving the assets of an ERISA Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of an ERISA Plan or the management or disposition of the assets of an ERISA Plan, or who renders investment advice for a fee or other compensation to an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan.

In considering an investment in our Class A common stock with a portion of the assets of any Plan, a fiduciary should consider the Plan’s particular circumstances and all of the facts and circumstances of the investment and determine whether the purchase and holding of shares of our Class A common stock is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code, or any Similar Law relating to the fiduciary’s duties to the Plan, including, without limitation:

• whether the investment is prudent under Section 404(a)(1)(B) of ERISA and any other applicable Similar Laws;

• whether, in making the investment, the ERISA Plan will satisfy the diversification requirements of Section 404(a)(1)(C) of ERISA and any other applicable Similar Laws;

• whether the investment is permitted under the terms of the applicable documents governing the Plan;

• whether the purchase or holding of shares of our Class A common stock will constitute a “prohibited transaction” under Section 406 of ERISA or Section 4975 of the Code (please see the discussion under “—Prohibited Transaction Issues” below); and

• whether the Plan will be considered to hold, as plan assets, (i) only shares of our Class A common stock or (ii) an undivided interest in our underlying assets (please see the discussion under “—Plan Asset Issues” below).

Prohibited Transaction Issues

Section 406 of ERISA and Section 4975 of the Code prohibit ERISA Plans from engaging in specified transactions involving plan assets with persons or entities who are “parties in interest,” within the meaning of ERISA, or “disqualified persons,” within the meaning of Section 4975 of the Code, unless an exemption is available. A party in interest or disqualified person who engages in a non-exempt prohibited transaction may be

12

subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the ERISA Plan that engages in such a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and the Code. The purchase and/or holding of shares of our Class A common stock by an ERISA Plan with respect to which the issuer, the initial purchaser, or a guarantor is considered a party in interest or a disqualified person may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless the investment is purchased and is held in accordance with an applicable statutory, class or individual prohibited transaction exemption.

Because of the foregoing, shares of our Class A common stock should not be purchased or held by any person investing “plan assets” of any Plan, unless such purchase and holding will not constitute a non-exempt prohibited transaction under ERISA and the Code or a similar violation of any applicable Similar Laws.

Plan Asset Issues

Additionally, a fiduciary of a Plan should consider whether the Plan will, by investing in us, be deemed to own an undivided interest in our assets, with the result that we would become a fiduciary of the Plan and our operations would be subject to the regulatory restrictions of ERISA, including its prohibited transaction rules, as well as the prohibited transaction rules of the Code and any other applicable Similar Laws.

The Department of Labor (the “DOL”) regulations provide guidance with respect to whether the assets of an entity in which ERISA Plans acquire equity interests would be deemed “plan assets” under some circumstances. Under these regulations, an entity’s assets generally would not be considered to be “plan assets” if, among other things:

(a)     the equity interests acquired by ERISA Plans are “publicly offered securities” (as defined in the DOL regulations)—i.e., the equity interests are part of a class of securities that is widely held by 100 or more investors independent of the issuer and each other, are freely transferable, and are either registered under certain provisions of the federal securities laws or sold to the ERISA Plan as part of a public offering under certain conditions;

(b)     the entity is an “operating company” (as defined in the DOL regulations)—i.e., it is primarily engaged in the production or sale of a product or service, other than the investment of capital, either directly or through a majority-owned subsidiary or subsidiaries; or

(c)     there is no significant investment by “benefit plan investors” (as defined in the DOL regulations)—i.e., immediately after the most recent acquisition by an ERISA Plan of any equity interest in the entity, less than 25% of the total value of each class of equity interest (disregarding certain interests held by persons (other than benefit plan investors) with discretionary authority or control over the assets of the entity or who provide investment advice for a fee (direct or indirect) with respect to such assets, and any affiliates thereof) is held by ERISA Plans, Individual Retirement Accounts and certain other Plans (but not including governmental plans, foreign plans and certain church plans), and entities whose underlying assets are deemed to include plan assets by reason of a Plan’s investment in the entity.

Due to the complexity of these rules and the excise taxes, penalties and liabilities that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries, or other persons considering purchasing and/or holding shares of our Class A common stock on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether an exemption would be applicable to the purchase and holding of shares of our Class A common stock. Purchasers of shares of our Class A common stock have the exclusive responsibility for ensuring that their purchase and holding of shares of our Class A common stock complies with the fiduciary responsibility rules of ERISA and does not violate the prohibited transaction rules of ERISA, the Code or applicable Similar Laws. The sale of shares of our Class A common stock to a Plan is in no respect a representation by us or any of our affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by any such Plan or that such investment is appropriate for any such Plan.
