SUMMARY

This summary highlights key information described in greater detail elsewhere in this prospectus supplement and the accompanying prospectus or documents incorporated by reference in the prospectus. The summary may not contain all the information that you should consider before investing in our securities. You should read the entire prospectus carefully, including “Risk Factors” contained in this prospectus supplement and the accompanying prospectus and the documents incorporated by reference, before making an investment decision.

CARBO Ceramics Inc. is an oilfield services technology company that generates revenue primarily through the sale of production enhancement products and services to the oil and natural gas industry. We were incorporated in 1987 in Delaware.

Our principal business consists of manufacturing and selling proppant products for use primarily in the hydraulic fracturing of oil and natural gas wells. These proppant products include ceramic, resin-coated proppants and raw frac sand. We also provide one of the industry’s most widely used hydraulic fracture simulation software, FracPro^®, as well as hydraulic fracture design and consulting services. In addition, we provide a broad range of technologies for spill prevention, containment and countermeasures. During the year ended December 31, 2015, we generated approximately 71% of our revenues in the United States and 29% in international markets.

Most of our products and services help oil and natural gas producers increase production and recovery rates from their wells, thereby lowering overall finding and development costs. As a result, our business is dependent to a large extent on the level of drilling and hydraulic fracturing activity in the oil and natural gas industry worldwide. Gross margin for our ceramic proppant business is principally impacted by sales volume, product mix, sales price, distribution costs, manufacturing costs, including natural gas, and our production levels as a percentage of our capacity.

Our principal executive office is located at 575 North Dairy Ashford, Suite 300, Houston, Texas 77079 and our telephone number is (281) 921-6400.

THE OFFERING

Common stock offered by us Shares of our common stock having an aggregate offering price of up to $75,000,000.

Common Stock outstanding immediately prior to this offering 23,498,241 shares.

Manner of offering “At the market offering” that may be made from time to time through our sales agent, Cowen. See “Plan of Distribution” on page S-6.

Listing Our common stock is currently traded on the NYSE under the symbol “CRR.”

Use of Proceeds The net proceeds from the sale of our securities offered by this prospectus supplement will be used for general corporate purposes and working capital needs. As a result, unless otherwise indicated in a free writing prospectus, our management will have broad discretion to allocate the net proceeds of the offerings. Pending the application of the net proceeds, we intend to invest the net proceeds in bank deposits or investment-grade and interest-bearing securities subject to any investment policies our management may determine from time to time.

Risk Factors Investing in our common stock involves risks. You should carefully consider the risks described under “Risk Factors” in this prospectus supplement, in our most recent Annual Report on Form 10-K and our subsequent quarterly reports on Form 10-Q, as well as the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus before making a decision to invest in our common stock.

S-2

RISK FACTORS

Investing in our common stock involves a high degree of risk. Before making an investment decision, you should carefully consider all risk factors set forth in this prospectus supplement and the accompanying prospectus and the documents incorporated by reference in this prospectus supplement, including the factors discussed under the heading “Risk Factors” in our most recent annual report on Form 10-K and each subsequently filed quarterly report on Form 10-Q, which may be amended, supplemented or superseded from time to time by the other reports we file with the SEC in the future. See “Where You Can Find More Information” in the accompanying prospectus. The risks and uncertainties we have described are not the only risks we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations and financial condition. If any of these risks actually occurs, our business, results of operations and financial condition could be materially and adversely affected, which could cause the trading price of our securities to decline, and you could lose all or a part of your investment in our common stock.

Risks Related to this Offering

Management will have broad discretion as to the use of the proceeds from this offering, and its use of the proceeds may not improve our financial condition or market value of our common stock.

Because we have not designated the amount of net proceeds received by us from this offering to be used for any particular purpose, our management will have broad discretion as to the application of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of the offering. Our management may use the net proceeds for corporate purposes that may not improve our financial condition or market value.

Sales of a significant number of shares of our common stock in the public markets, or the perception that such sales could occur, could depress the market price of our common stock.

Sales of a substantial number of shares of our common stock in the public markets, or the perception that such sales could occur, could depress the market price of our common stock and impair our ability to raise capital through the sale of additional equity securities.

Because we do not intend to declare cash dividends on our shares of common stock in the foreseeable future, stockholders must rely on appreciation of the value of our common stock for any return on their investment.

We currently anticipate that we will retain any earnings for the operation of our business and do not anticipate declaring or paying any cash dividends in the foreseeable future. In addition, the terms of our existing credit facility preclude and future debt agreements may preclude us from paying dividends. As a result, we expect that only appreciation of the price of our common stock, if any, will provide a return to investors in this offering for the foreseeable future.

The common stock is equity and therefore is subordinate to our indebtedness and preferred stock.

Shares of our common stock are equity interests in the Company and do not constitute indebtedness. As such, shares of our common stock will rank junior to all indebtedness and other non-equity claims on us with respect to assets available to satisfy claims on the Company, including in a liquidation of us. As of June 30, 2016, our long-term debt and other borrowings over one year, on a consolidated basis, totaled approximately $74,401,000. Additionally, holders of our common stock are subject to the prior dividend and liquidation rights of any holders of our preferred stock then outstanding. If we issue preferred stock in the future that have a preference over our common stock

S-3

with respect to the payment of dividends or upon liquidation, or if we issue preferred stock with voting rights that dilute the voting power of the common stock, the rights of holders of our common stock or the market price of our common stock could be adversely affected. We are not restricted from issuing additional indebtedness or preferred stock, subject to any required approvals from our creditors.

S-4

USE OF PROCEEDS

The net proceeds from the sale of our securities offered by this prospectus supplement will be used for general corporate purposes and working capital needs. As a result, unless otherwise indicated in a free writing prospectus, our management will have broad discretion to allocate the net proceeds of the offerings. Pending the application of the net proceeds, we intend to invest the net proceeds in bank deposits or investment-grade and interest-bearing securities subject to any investment policies our management may determine from time to time.

S-5

PLAN OF DISTRIBUTION

We have entered into a sales agreement with Cowen, under which we may issue and sell from time to time up to $75,000,000 of our common stock through Cowen as our sales agent. Sales of our common stock, if any, will be made at market prices by any method that is deemed to be an “at the market offering” as defined in Rule 415 under the Securities Act, including sales made directly on the New York Stock Exchange or any other trading market for our common stock, or sales to or through a market maker other than on an exchange. If authorized by us in writing, Cowen may also sell our shares of common stock by any other method permitted by law, including negotiated transactions, and Cowen may also purchase shares of our common stock as principal.

Cowen will offer our common stock subject to the terms and conditions of the sales agreement on a daily basis or as otherwise agreed upon by us and Cowen. We will designate the maximum amount of common stock to be sold through Cowen on a daily basis or otherwise determine such maximum amount together with Cowen. Subject to the terms and conditions of the sales agreement, Cowen will use its commercially reasonable efforts to sell on our behalf all of the shares of common stock requested to be sold by us. We may instruct Cowen not to sell common stock if the sales cannot be effected at or above the price designated by us in any such instruction. Cowen or we may suspend the offering of our common stock being made through Cowen under the sales agreement upon proper notice to the other party. Cowen and we each have the right, by giving written notice as specified in the sales agreement, to terminate the sales agreement in each party’s sole discretion at any time.

The aggregate compensation payable to Cowen as sales agent equals up to 3.0% of the gross sales price of the shares sold through it pursuant to the sales agreement. We have also agreed to reimburse Cowen up to $50,000 of Cowen’s actual outside legal expenses incurred by Cowen in connection with this offering. We estimate that the total expenses of the offering payable by us, excluding commissions payable to Cowen under the sales agreement, will be approximately $120,000.

The remaining sales proceeds, after deducting any expenses payable by us and any transaction fees imposed by any governmental, regulatory, or self-regulatory organization in connection with the sales, will equal our net proceeds for the sale of such common stock.

Cowen will provide written confirmation to us following the close of trading on the New York Stock Exchange on each day in which common stock is sold through it as sales agent under the sales agreement. Each confirmation will include the number of shares of common stock sold through it as sales agent on that day, the volume weighted average price of the shares sold, the percentage of the daily trading volume and the net proceeds to us.

We will report at least quarterly the number of shares of common stock sold through Cowen under the sales agreement, the net proceeds to us and the compensation paid by us to Cowen in connection with the sales of common stock.

Settlement for sales of common stock will occur, unless the parties agree otherwise, on the third business day that is also a trading day following the date on which any sales were made in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

In connection with the sales of our common stock on our behalf, Cowen may be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to Cowen may be deemed to be underwriting commissions or discounts. We have agreed in the sales agreement to provide indemnification and contribution to Cowen against certain liabilities, including liabilities under the Securities Act. As sales agent, Cowen will not engage in any transactions that stabilizes our common stock.

S-6

Our common stock is listed on the New York Stock Exchange and trades under the symbol “CRR.” The transfer agent of our common stock is Computershare Trust Company, N.A.

Cowen and/or its affiliates have provided, and may in the future provide, various investment banking and other financial services for us for which services they have received and, may in the future receive, customary fees.

S-7

RISK FACTORS

Investing in our securities involves a high degree of risk. Before making an investment decision, you should carefully consider all risk factors set forth in the applicable prospectus supplement and the documents incorporated by reference in this prospectus, including the factors discussed under the heading “Risk Factors” in our most recent annual report on Form 10-K and each subsequently filed quarterly report on Form 10-Q, which may be amended, supplemented or superseded from time to time by the other reports we file with the SEC in the future. See “Where You Can Find More Information.” The risks and uncertainties we have described are not the only risks we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations and financial condition. If any of these risks actually occurs, our business, results of operations and financial condition could be materially and adversely affected, which could cause the trading price of our securities to decline, and you could lose all or a part of your investment in our securities.

We refer in this section to our restated certificate of incorporation as our certificate of incorporation, and we refer to our second amended and restated by-laws as our by-laws.

Common Stock

Our authorized capital stock consists of 80,000,000 shares of our common stock, par value $0.01 per share and 5,000 shares our of our preferred stock, par value $0.01 per share. As of December 31, 2015, we had 23,280,696 shares of common stock outstanding.

Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. An election of directors by our stockholders shall be determined by a plurality of the votes cast by the stockholders entitled to vote on the election. Holders of common stock are entitled to receive any dividends as may be declared by our board of directors, subject to any preferential dividend rights of outstanding preferred stock.

In the event of our liquidation, dissolution or winding up, the holders of common stock are entitled to receive proportionately all assets available for distribution to stockholders after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights. The rights, preferences and privileges of holders of common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

Preferred Stock

The following is a description of general terms and provisions of our preferred stock. The particular terms of any series of preferred stock will be described in the applicable prospectus supplement. All of the terms of the preferred stock are, or will be, contained in our articles of incorporation and any resolutions which may be adopted by our board of directors relating to any series of the preferred stock, which will be filed with the SEC at or before the time we issue a series of the preferred stock.

We are authorized to issue up to 5,000 shares of preferred stock, $0.01 par value, none of which are issued and outstanding. Subject to limitations prescribed by law, the board of directors is authorized at any time to:

• issue one or more series of preferred stock;

• determine the designation for any series by number, letter or title that shall distinguish the series from any other series of preferred stock; and

• determine the number of shares in any series.

The board of directors is authorized to determine, and the applicable prospectus supplement will set forth, the terms with respect to the series of preferred stock being offered, which may include (without limitation) the following:

• the voting rights, if any;

• any redemption or sinking fund provisions;

4

• preferential rights to receive dividends, if any;

• the preference rights to assets upon liquidation, if any;

• the rights of conversion into common stock or other securities, if any; and

• the terms of any other preferences, limitations or relative rights, if any, applicable.

The preferred stock, when issued, will be fully paid and nonassessable.

Delaware Anti-Takeover Law and Certain Charter and By-law Provisions

Section 203 of the Delaware General Corporation Law

We are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a publicly-held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a three-year period following the time that this stockholder becomes an interested stockholder, unless the business combination is approved in a prescribed manner. A “business combination” includes, among other things, a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns, or did own within three years prior to the determination of interested stockholder status, 15% or more of the corporation’s voting stock.

Under Section 203, a business combination between a corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions: before the stockholder became interested, the board of directors approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder; upon consummation of the transaction which 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, excluding for purposes of determining the voting stock outstanding, shares owned by persons who are directors and also officers, and employee stock plans, in some instances; or at or after the time the stockholder became interested, the business combination was approved by the board of directors of the corporation and authorized at an annual or special meeting of the stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.

A Delaware corporation may “opt out” of these provisions with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or by-laws resulting from a stockholders’ amendment approved by at least a majority of the outstanding voting shares. We have not opted out of these provisions. As a result, mergers or other takeover or change in control attempts of us may be discouraged or prevented.

Anti-Takeover Effects of Our Certificate of Incorporation and Our By-Laws

Our certificate of incorporation and by-laws contain certain provisions that are intended to enhance the likelihood of continuity and stability in the composition of the board of directors and which may have the effect of delaying, deferring or preventing a future takeover or change in control of the Company unless such takeover or change in control is approved by the board of directors.

These provisions include:

Advance Notice Procedures. Our by-laws establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to the board of directors. Stockholders at an annual meeting are only be able to consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the board of

5

directors or by a stockholder who was a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has given our Secretary timely written notice, in proper form, of the stockholder’s intention to bring that business before the meeting. Although the by-laws do not give the board of directors the power to approve or disapprove stockholder nominations of candidates or proposals regarding other business to be conducted at a special or annual meeting, the by-laws may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed or may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempting to obtain control of the Company.

Authorized but Unissued Shares. Our authorized but unissued shares of common stock and preferred stock are available for future issuance without stockholder approval. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued shares of common stock and preferred stock could render more difficult or discourage an attempt to obtain control of a majority of our common stock by means of a proxy contest, tender offer, merger or otherwise.

DESCRIPTION OF OUR DEBT SECURITIES

We may issue debt securities from time to time in one or more series. The debt securities will be our direct obligations and may be guaranteed by certain of our subsidiaries, as determined on a case by case basis for each series of debt securities. The debt securities will be either senior debt securities or subordinated debt securities. The debt securities will be issued under one or more separate indentures between us and a banking or financial institution, as trustee. A successor trustee may be appointed in accordance with the terms of the applicable indenture.

Senior debt securities will be issued under a senior indenture and subordinated debt securities will be issued under a subordinated indenture. The prospectus supplement relating to a particular issue of debt securities will describe the terms of those debt securities and the related indenture, which may include (without limitation) the following:

• the title and series of the debt securities;

• any limit on the aggregate principal amount of the debt securities;

• the price or prices at which the debt securities will be issued;

• the maturity date or dates, or the method of determining the maturity date or dates, of the debt securities;

• the interest rate or rates (which may be fixed or variable) per annum of the debt securities or the method of determining the interest rate or rates of the debt securities;

• any conversion or exchange features;

• if applicable, the date or dates from which interest on the debt securities will accrue or the method or methods by which the date or dates are to be determined, the interest payment dates, the date or dates on which payment of interest will commence and the regular record dates for such interest payment dates;

• if applicable, the date after which and the price or prices at which the debt securities may, pursuant to any optional redemption provisions, be redeemed at our option or of the holders of the debt securities and the other detailed terms and provisions of such optional redemption;

• the extent to which any of the debt securities will be issuable in temporary or permanent global form and, if so, the identity of the depositary for the global debt security, or the manner in which any interest payable on a temporary or permanent global debt security will be paid;

• the denomination or denominations of debt securities;

6

• whether the debt securities will be issued in registered or bearer form or both and, if in bearer form, the related terms and conditions and any limitations on issuance of these bearer debt securities (including exchange for registered debt securities of the same series);

• information with respect to book-entry procedures;

• whether any of the debt securities will be issued as original issue discount securities;

• each office or agency where, subject to the terms of the indenture, the debt securities may be presented for registration of transfer or exchange;

• if other than the U.S. dollar, the currencies or currency units in which the debt securities are issued and in which the principal of, premium and interest, if any, on, and additional amounts, if any, in respect of the debt securities will be payable;

• if other than the trustee, the identity of each security registrar, paying agent and authenticating agent; and

• any other terms of the debt securities.

The indenture will be governed by and construed in accordance with the laws of the State of New York. Notices to holders of debt securities will be given by mail to the addresses of such holders as they appear in the security register for such debt securities.

No director, officer, employee or shareholder, as such, of ours or any of our affiliates shall have any personal liability in respect of our obligations under the indenture or the debt securities by reason of his, her or its status as such.

The indenture and the provisions of the Trust Indenture Act incorporated by reference therein will contain certain limitations on the rights of the trustee, should it become a creditor to us, to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest (within the meaning of the Trust Indenture Act), it must eliminate such conflicting interest or resign.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of our debt securities, preferred stock or common stock. Warrants may be issued independently or together with any of the debt securities, preferred stock or common stock offered by a prospectus supplement, and may be attached to or separate from those offered securities. Each series of warrants will be issued under separate warrant agreements to be entered into between us and a bank or trust company, as warrant agent (the “Warrant Agent”), all as further set forth in the prospectus supplement relating to the particular issue of warrants. The Warrant Agent will act solely as our agent in connection with the warrant certificates and will not assume any obligation or relationship of agency or trust for or with any holders of warrant certificates or beneficial owners of warrants. A copy of the form of warrant agreement, including the form of warrant certificate representing a series of warrants, will be filed with the SEC in connection with the offering of a particular series of warrants.

Each series of rights will be issued under a separate rights agreement to be entered into between us and a bank or trust company, as rights agent. The following description of the rights and any description of the rights in a prospectus supplement may not be complete and is subject to, and qualified in its entirety by reference to, the underlying rights agreement, which we will file with the SEC at or prior to the time of the sale of the rights. You should refer to, and read this summary together with, the rights agreement and the applicable prospectus supplement to review the terms of a particular series of rights.

If less than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than existing shareholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby underwriting arrangements, as described in the applicable prospectus supplement.

DESCRIPTION OF UNITS

We may issue units that include senior or subordinated debt securities, common stock, preferred stock, rights, warrants or other securities. Each unit will be issued under a unit agreement or indenture and will represent an interest in two or more securities, which may or may not be separable from one another.

SELLING SECURITY HOLDERS

To the extent that this prospectus is used by any selling security holder to resell any senior or subordinated debt securities, preferred stock, common stock or other securities, information with respect to the selling security holder and the plan of distribution will be contained in a supplement to this prospectus, in a post-effective amendment or in filings we make with the SEC under the Securities Exchange Act of 1934 which are incorporated by reference.

PLAN OF DISTRIBUTION

We may sell the securities from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods or through underwriters or dealers, through agents and/or directly to one or more purchasers. The securities may be distributed from time to time in one or more transactions:

• in one or more transactions at a fixed price or prices, which may be changed;

• at prevailing market prices at the time of sale or at prices related to such prevailing prices;

• at prices related to such prevailing market prices (including in “at-the-market” offerings in accordance with Rule 415(a)(4));

• at varying prices determined at the time of sale; or

• at negotiated prices.

The securities may be sold:

• in transactions on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;

• in transactions in the over-the-counter market;

• in transactions otherwise than on such exchanges or services or in the over-the-counter market;

• in block transactions in which the broker or dealer so engaged will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction, or in crosses;

• through purchases by a broker or dealer as principal and resale by such broker or dealer for its own account pursuant to this prospectus;

• in ordinary brokerage transactions and transactions in which the broker solicits purchasers;

• through the writing of options; or

• through other types of transactions.

At the time a particular offering of securities is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of securities being offered and the terms of the offering, including the name or names of any underwriters, dealers, brokers or agents and any discounts, commissions or concessions allowed or reallowed or paid to brokers or dealers. If we utilize a dealer in the sale of the securities being offered by this prospectus, the securities will be sold to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

If we utilize an underwriter in the sale of the securities being offered by this prospectus, we will execute an underwriting agreement with the underwriter at the time of sale and provide the name of any underwriter in the prospectus supplement that the underwriter will use to make resales of the securities to the public.

10

Any compensation paid to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers will be provided in the applicable prospectus supplement. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof and to reimburse those persons for certain expenses.

To facilitate the offering of securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involve the sale by persons participating in the offering of more securities than were sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option, if any. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

If indicated in the applicable prospectus supplement, underwriters or other persons acting as agents may be authorized to solicit offers by institutions or other suitable purchasers to purchase the securities at the public offering price set forth in the prospectus supplement, pursuant to delayed delivery contracts providing for payment and delivery on the date or dates stated in the prospectus supplement. These purchasers may include, among others, commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions. Delayed delivery contracts will be subject to the condition that the purchase of the securities covered by the delayed delivery contracts will not at the time of delivery be prohibited under the laws of any jurisdiction in the United States to which the purchaser is subject. The underwriters and agents will not have any responsibility with respect to the validity or performance of these contracts.

The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business for which they receive compensation.
