We have not authorized anyone to provide you with different information. If anyone provides you with different or inconsistent information, you must not rely on it as having been authorized by us.

We, and our underwriters or agents, reserve the right to accept or reject all or part of any proposed purchase of securities.

PROSPECTUS SUMMARY

The following summary highlights selected information contained elsewhere in this prospectus or incorporated by reference into this prospectus. It does not contain all the information you should consider before investing in our securities. You should read carefully this prospectus, any accompanying prospectus supplement and any other offering materials, together with the additional information described under “Where To Learn More About Us” and “Incorporation of Certain Documents By Reference” in this prospectus.

As used in this prospectus, the terms “we,” “us,” “our,” and “Company” refer to KMG Chemicals, Inc. and its subsidiaries.

The Company

We were incorporated in 1992 as a Texas corporation. We manufacture, formulate and globally distribute specialty chemicals through our four wholly owned subsidiaries, KMG Electronic Chemicals, Inc., KMG Val-Tex, LLC, Sealweld Corporation (2003), Inc. and KMG-Bernuth, Inc. We grow primarily by purchasing product lines and businesses that operate in segments of the specialty chemical industry that:

•

provide an opportunity to obtain a significant share of the market segment through further acquisitions and organic growth;

•

are of a size that larger industry participants generally find too small to be attractive;

•

have niche products with well-established and proven commercial uses;

•

offer products that have moved well beyond their discovery phase and require little or no on-going research and development expenditures; and

•

have significant barriers to entry.

We operate businesses selling electronic chemicals, industrial valve lubricants and sealants and industrial wood treating chemicals. Our electronic chemicals segment provides high purity and ultra purity, wet process chemicals to the semiconductor industry, primarily to clean and etch silicon wafers in the production of semiconductors. We are the leading supplier of these wet process chemicals to the semiconductor industry in the United States and have a significant presence in Europe and Singapore. Our industrial valve lubricants and sealants enable optimal valve operation and provide important safety and environmental benefits, including preventing fugitive emissions and minimizing costly downtime at oil and gas storage facilities and pipelines. Our wood treating chemicals, based on pentachlorophenol, or penta, are sold to industrial customers who use these preservatives to extend the useful life of wood utility poles and crossarms. We are the only producer of penta in North America.

Corporate Information

Our principal executive offices are located at 300 Throckmorton Street, Fort Worth, Texas 76102, and our telephone number is (817) 761-6100. Our website address is www.kmgchemicals.com. The information on our website is not incorporated by reference into this prospectus and does not constitute a part of this prospectus.

The Securities We May Offer

We may offer up to $200,000,000 of debt securities, common stock, preferred stock, depositary shares, and warrants in one or more offerings and in any combination. This prospectus provides you with a general description of the securities we may offer. This prospectus may not be used to offer or sell securities unless accompanied by a prospectus supplement.

RISK FACTORS

An investment in our securities involves a high degree of risk. The prospectus supplement applicable to each offering of our securities will contain a discussion of the risks applicable to an investment in our securities. Before deciding whether to invest in our securities, you should carefully consider the specific factors discussed under the heading “Risk Factors” in the applicable prospectus supplement, together with all of the other information contained or incorporated by reference in the prospectus supplement or appearing or incorporated by reference in this prospectus. You should also consider the risks, uncertainties and assumptions discussed under Item 1A, “Risk Factors,” in our Annual Report on Form 10-K, for the fiscal year ended July 31, 2016, filed with the SEC on October 14, 2016, which is incorporated herein by reference, as updated or superseded by the risks and uncertainties described under similar headings in the other documents that are filed after the date hereof and incorporated by reference into this prospectus and any prospectus supplement related to a particular offering. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, business prospects, financial condition or results of operations could be seriously harmed. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment. Please also read carefully the section below entitled “Cautionary Note Regarding Forward-Looking Statements.”

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and each prospectus supplement contains, and the documents incorporated by reference herein include “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. These statements relate to future events or to our future financial performance and involve known and unknown risks, uncertainties and other factors which may cause our actual results, performance or achievements to be materially different from any future results, performances or achievements expressed or implied by the forward-looking statements. Some of the key factors which could cause our future financial results and performance to vary from those expected include:

•

the loss or significant reduction in business from primary customers;

•

the loss of key suppliers;

•

the implementation of our strategy with respect to the expansion of operations in Singapore taking longer or being more costly than currently believed, and the failure to achieve all the planned benefits of that effort;

•

our ability to implement productivity improvements, cost reduction initiatives or facilities expansions;

•

market developments affecting, and other changes in, the demand for our products and the entry of new competitors or the introduction of new competing products;

•

volatility in oil and natural gas prices, which may impact customers’ activity levels and spending for our products and services and which could impact goodwill impairment testing for our industrial lubricants business;

•

increases in the price of energy, affecting our primary raw materials and active ingredients;

•

the timing of planned capital expenditures;

•

our ability to identify, develop or acquire, and market additional product lines and businesses necessary to implement our business strategy and our ability to finance such acquisitions and development;

•

our ability to realize the anticipated benefits of business acquisitions and to successfully integrate previous or future business acquisitions;

•

the condition of the capital markets generally, which will be affected by interest rates, foreign currency fluctuations and general economic conditions;

•

cost and other effects of legal and administrative proceedings, settlements, investigations and claims, including environmental liabilities which may not be covered by indemnity or insurance;

•

the effects of weather, earthquakes, other natural disasters and terrorist attacks;

•

the impact of penta being banned or restricted as a persistent organic pollutant under the Stockholm Convention Treaty and the ability to obtain registration and re-registration of our products under applicable law;

•

exposure to movements in foreign currency exchange rates as a result of the geographic diversity of our operations;

•

the political and economic climate in the foreign or domestic jurisdictions in which we conduct business; and

•

other United States or foreign regulatory or legislative developments which affect the demand for our products generally or increase the environmental compliance cost for our products or impose liabilities on the manufacturers and distributors of such products.

In some cases, you can identify forward-looking statement by terms such as “believe,” “may,” “estimate,” “continue,” “anticipate,” “intend,” “should,” “could,” “would,” “target,” “seek,” “aim,” “believe,” “predict,” “think,” “objectives,” “optimistic,” “new,” “goal,” “strategy,” “potential,” “is likely,” “will,” “expect,” “plan,” “project,” “permit” and similar expressions intended to identify forward-looking statements. These statements reflect our current views with respect to future events, are based on assumptions and are subject to risks and uncertainties. Given these uncertainties, you should not place undue reliance on these forward-looking statements. We discuss many of these risks in greater detail under the heading “Risk Factors” in our SEC filings, and under the caption “Risk Factors” in this prospectus or any prospectus supplement. Also, these forward-looking statements represent our estimates and assumptions only as of the date of the document containing the applicable statement. You should read this prospectus, the registration statement of which this prospectus is a part, any prospectus supplement and the exhibits and documents incorporated by reference herein and therein completely and with the understanding that our actual future results may be materially different from those described in forward-looking statements. We qualify all of the forward-looking statements in the foregoing documents by these cautionary statements.

You should assume that information contained in or incorporated by reference into this prospectus is accurate only as of the date on the front cover of this prospectus or the date of the document incorporated by reference, as applicable. Unless required by law, we undertake no obligation to update or revise any forward-looking statements to reflect new information or future events or developments.

DESCRIPTION OF SECURITIES TO BE OFFERED

The descriptions of the securities contained in this prospectus, together with the applicable prospectus supplements, summarize the material terms and provisions of the various types of securities that we may offer. We will describe in the applicable prospectus supplement relating to any securities the particular terms of the securities offered by that prospectus supplement. If we so indicate in the applicable prospectus supplement, the terms of the securities may differ from the terms we have summarized below. We will also include information in the prospectus supplement, where applicable, about material U.S. federal income tax considerations relating to the securities, and the securities exchange, if any, on which the securities will be listed.

We may sell from time to time, in one or more primary offerings, our debt securities, common stock, preferred stock, depositary shares, and warrants, or any combination of the foregoing.

In this prospectus, we refer to the debt securities, common stock, preferred stock, depositary shares, and warrants or any combination of the foregoing securities to be sold by us in a primary offering collectively as “securities.” The total dollar amount of all securities that we may issue under this prospectus will not exceed $200,000,000.

The following is a summary of the material provisions of the securities as set forth in our articles of incorporation, as amended to date, and bylaws, as amended to date. For additional detail about our capital stock, please refer to our amended and restated articles of incorporation and amended and restated bylaws, as well as applicable Texas law.

Description of Debt Securities

The following description sets forth certain general terms and provisions of the debt securities to which any prospectus supplement may relate. Other terms, and the particular terms of a specific series of debt securities (which differ from the terms described below), will be described in the prospectus supplement relating to that series. The debt securities will be senior debt securities or subordinated debt securities. The senior debt securities will be issued under an indenture (the “Senior Indenture”), to be entered into between us and a trustee named in the applicable prospectus supplement, as trustee (the “Senior Trustee”), and the subordinated debt securities will be issued under a separate indenture (the “Subordinated Indenture”), to be entered into between us and a trustee to be named in the applicable prospectus supplement, as trustee (the “Subordinated Trustee”). The term “Trustee” used in this prospectus shall refer to the Senior Trustee or the Subordinated Trustee, as appropriate. The Senior Indenture and the Subordinated Indenture are sometimes collectively referred to herein as the “Indentures” and individually as “Indenture.” The Indentures are subject to and governed by the Trust Indenture Act of 1939, as amended (the “TIA”), and may be supplemented from time to time following execution.

The terms of the debt securities include those stated in the applicable Indenture and those made part of the Indenture by reference to the TIA. The debt securities are subject to all of those terms, and holders of debt securities are referred to the applicable Indenture and the TIA for a statement of those terms.

The statements set forth below in this section are brief summaries of certain provisions contained in the Indentures, do not purport to be complete, and are subject to, and are qualified in their entirety by reference to, the Indentures, including the definitions of certain terms therein, and the TIA. Capitalized terms used in this section and not otherwise defined in this section will have the respective meanings assigned to them in the Indentures.

General

The debt securities will be our direct, unsecured obligations. The indebtedness represented by the senior debt securities will rank equally with all of our other unsecured and unsubordinated indebtedness. The indebtedness represented by the subordinated debt securities will be subordinated in right of payment to the prior payment in full of all of our senior debt as described below under “Subordination.”

A prospectus supplement, the applicable Indenture and the supplemental indenture, if any, relating to any series of debt securities being offered will include specific terms relating to the offering. These terms will include some or all of the following:

•

the form and title of the debt securities and whether the debt securities are senior debt securities or subordinated debt securities;

•

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

•

the issue price or prices of the debt securities, including any original issue discount;

•

the date or dates on which the principal of the debt securities shall be payable;

•

the rate or rates (fixed or variable) at which the debt securities shall bear interest, if any, and the date or dates from which the interest shall accrue;

•

the dates on which interest, if any, shall be payable and the record dates for the interest payment dates;

•

the place or places where the principal of and interest, if any, on the debt securities of the series will be payable;

•

any optional or mandatory redemption or any sinking fund or analogous provisions;

•

the denomination of the securities;

•

if principal or interest will be determined by reference to any commodity, currency or index, the manner in which principal or interest, if any, will be determined;

•

the currency in which principal and interest, if any, will be payable;

•

if other than the entire principal amount, the portion of the principal amount of securities which shall be payable upon acceleration;

•

any provisions relating to defeasance;

•

events of default and covenants applicable to the securities;

•

any provisions relating to the conversion of the securities for debt of equity securities or other securities or property of the Company or any other person;

•

provisions relating to the modification of the terms of the debt securities or the rights of security holders;

•

the identity of the trustee, the registrar for the debt securities and any paying agent; and

•

any other terms not inconsistent with the provisions of the applicable Indenture.

The debt securities of a series may be issued in registered, coupon or global form and will be denominated in an amount equal to all or a portion of the aggregate principal amount of those debt securities. See “Global Debt Securities.”

Denominations

Unless otherwise indicated in any applicable prospectus supplement, the debt securities of any series will be issued only in fully registered form in a denomination equal to $2,000 or an integral multiple of $1,000 in excess thereof.

Global Debt Securities

Certain series of the debt securities may be issued as permanent global debt securities to be deposited with a depositary with respect to that series. Unless otherwise indicated in the applicable prospectus supplement, the following is a summary of the depository arrangements applicable to debt securities issued in permanent global form and for which The Depository Trust Company, or DTC, acts as depositary.

Each global debt security will be deposited with, or on behalf of, DTC, as depositary, or its nominee and registered in the name of a nominee of DTC. Except under the limited circumstances described below, global debt securities are not exchangeable for definitive certificated debt securities.

Ownership of beneficial interests in a global debt security is limited to institutions that have accounts with DTC or its nominee (“participants”) or persons that may hold interests through participants. In addition, ownership of beneficial interests by participants in a global debt security will be evidenced only by, and the transfer of that ownership interest will be effected only through, records maintained by DTC or its nominee for a global debt security. Ownership of beneficial interests in a global debt security by persons that hold through participants will be evidenced only by, and the transfer of that ownership interest within that participant will be effected only through, records maintained by that participant. DTC has no knowledge of the actual beneficial owners of the debt securities. Beneficial owners will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the participants through which the beneficial owners entered the transaction. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may impair the ability to transfer beneficial interests in a global debt security.

Payment of principal of, and interest on, debt securities represented by a global debt security registered in the name of or held by DTC or its nominee will be made to DTC or its nominee, as the case may be, as the registered owner and holder of the global debt security representing the debt securities. We expect that upon receipt of any payment of principal of, or interest on, a global debt security, DTC will immediately credit accounts of participants on its book-entry registration and transfer system with payments in amounts proportionate to their respective beneficial interests in the principal amount of that global debt security as shown in the records of DTC. Payments by participants to owners of beneficial interests in a global debt security held through those participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the sole responsibility of those participants, subject to any statutory or regulatory requirements that may be in effect from time to time.

Neither we, any trustee nor any of our respective agents will be responsible for any aspect of the records of DTC, any nominee or any participant relating to, or payments made on account of, beneficial interests in a permanent global debt security or for maintaining, supervising or reviewing any of the records of DTC, any nominee or any participant relating to such beneficial interests.

A global debt security is exchangeable for definitive debt securities registered in the name of, and a transfer of a global debt security may be registered to, any person other than DTC or its nominee, only if:

•

DTC notifies us that it is unwilling or unable to continue as depositary for that global debt security or at any time DTC ceases to be registered under the Exchange Act;

•

we determine in our discretion that the global debt security shall be exchangeable for definitive debt securities in registered form; or

•

there shall have occurred and be continuing an event of default or an event which, with notice or the lapse of time or both, would constitute an event of default under the debt securities.

Any global debt security that is exchangeable pursuant to the preceding sentence will be exchangeable in whole for definitive debt securities in registered form, of like tenor and of an equal aggregate principal amount as the global debt security, in a denomination equal to $2,000 or an integral multiple of $1,000 in excess thereof. The definitive debt securities will be registered by the registrar in the name or names instructed by DTC. We expect that these instructions may be based upon directions received by DTC from its participants with respect to ownership of beneficial interests in the global debt security. Except as provided above, owners of the beneficial interests in a global debt security will not be entitled to receive physical delivery of debt securities in definitive form and will not be considered the holders of debt securities for any purpose under the indentures. No global debt security shall be exchangeable except for another global debt security of like denomination and tenor to be registered in the name of DTC or its nominee. Accordingly, each person owning a beneficial interest in a global debt security must rely on the procedures of DTC and, if that person is not a participant, on the procedures of the participant through which that person owns its interest, to exercise any rights of a holder under the global debt security or the Indentures.

We understand that, under existing industry practices, in the event that we request any action of holders, or an owner of a beneficial interest in a global debt security desires to give or take any action that a holder is entitled to give or take under the debt securities or the indentures, DTC would authorize the participants holding the relevant beneficial interest to give or take that action, and those participants would authorize beneficial owners owning through those participants to give or take that action or would otherwise act upon the instructions of beneficial owners owning through them.

DTC is a limited purpose trust company organized under the laws of the State of New York, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under the Exchange Act. DTC was created to hold securities of its participants and to facilitate the clearance and settlement of securities transactions among its participants in those securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to DTC’s book-entry system is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Payment and Transfer

Unless otherwise indicated in the applicable prospectus supplement, principal of, and interest and any premium on, our fully registered debt securities will be paid at designated places. Payment will be made by check and mailed to the persons in whose names our debt securities are registered on days specified in the applicable indenture or any prospectus supplement. Debt securities payments in other forms will be paid at a place designated by us and specified in a prospectus supplement.

Fully registered securities may be transferred or exchanged at the corporation trust office of the applicable Trustee or at any other office or agency maintained by us for such purposes, without the payment of any service charge except for any tax or governmental charge.

Covenants

Under the Indentures, we will agree to:

•

pay the principal of, and interest and any premium on, the debt securities when due;

•

maintain a place of payment;

•

deliver an officer’s certificate to the Trustee within 120 days after the end of each fiscal year reviewing our obligations under the Indentures; and

•

deposit sufficient funds with any paying agent on or before the due date for any payment of principal, interest or premium.

Events of Default

Unless otherwise specified in the applicable prospectus supplement, each of the following events will be an event of default under an Indenture with respect to any series of debt securities issued under that Indenture:

•

failure to pay principal of (or premium, if any, on) any debt security of the series when due;

•

failure to deposit a sinking fund or any other such analogous required payment, if any, when due by the terms of a debt security of the series;

•

failure to pay any interest on any debt security of the series when due, continued for 30 days;

•

failure to perform or comply with any covenant in the applicable Indenture or related supplemental indenture, continued for 90 days after written notice as provided in the Indenture;

•

certain events in bankruptcy, insolvency or reorganization affecting us; and

•

any other event of default set forth in the applicable indenture or supplemental indenture relating to the debt securities of that series.

An event of default for a particular series of debt securities does not necessarily constitute an event of default for any other series of debt securities issued under an Indenture. The applicable Trustee may withhold notice to the holders of a series of debt securities of any default, except payment defaults on those debt securities, if it considers such withholding to be in the interest of the holders.

If an event of default occurs and is continuing, then the applicable Trustee or the holders of a specified percentage in aggregate principal amount of the outstanding debt securities of that series may declare the entire principal amount of the debt securities of that series to be due and payable immediately; provided, however, that the holders of a majority of the aggregate principal amount of the debt securities of that series may, under certain circumstances, rescind and annul the declaration.

Subject to provisions in each Indenture relating to its duties in case an event of default shall have occurred and be continuing, no Trustee will be under an obligation to exercise any of its rights or powers under that Indenture at the request, order or direction of any holders of debt securities then outstanding under that Indenture, unless the holders shall have offered to the applicable Trustee reasonable indemnity. If such reasonable indemnity is provided, the holders of a majority in aggregate principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the applicable Trustee or exercising any power conferred on the Trustee, for any series of debt securities.

Defeasance

When we use the term “defeasance,” we mean a discharge from some or all of our obligations under the applicable Indenture. We may choose to either discharge our obligations on the debt securities of any series in a legal defeasance, or to be released from covenant restrictions on the debt securities of any series in a covenant defeasance. We may do so after we irrevocably deposit with the applicable trustee sufficient cash or government securities to pay the principal, interest, any premium and any other amounts due on the stated maturity date or a redemption date of the debt securities of the series. If we choose the legal defeasance option, the holders of the

debt securities of the series will not be entitled to the benefits of the applicable Indenture, except for certain obligations, including obligations to register the transfer or exchange of debt securities, to replace lost, stolen or mutilated debt securities, maintain a place of payment and certain other obligations set forth in the Indenture.

We may discharge our obligations under the Indentures or be released from covenant restrictions only if we meet certain requirements. Among other things, we must deliver to the Trustee an opinion of our legal counsel to the effect that holders of the series of debt securities will not recognize income, gain or loss for United States federal income tax purposes as a result of such defeasance. We may not have a default on the debt securities discharged existing on the date of deposit.

Subordination

Debt securities of a series may be subordinated to our “Senior Indebtedness,” which we define generally as money borrowed, including guarantees, by us that is not expressly subordinate or junior in right of payment to any of our other indebtedness. Subordinated debt securities will be subordinate in right of payment, to the extent and in the manner set forth in the indenture, and related supplemental indenture, and the prospectus supplement relating to such series, to the prior payment of all of our indebtedness that is designated as “Senior Indebtedness” with respect to the series. Under a subordinated indenture, payment of the principal, interest and premium, if any, on the subordinated debt securities will generally be subordinated and junior in right of payment to the prior payment in full of all senior debt. The Subordinated Indenture will provide that no payment of principal, interest and any premium on the subordinated debt securities may be made in the event:

•

we fail to pay the principal, interest, premium, if any, or any other amounts on any Senior Indebtedness when due; or

•

any other default on Senior Indebtedness occurs and the maturity of such Senior Indebtedness is accelerated in accordance with its terms unless, in either case, the default has been cured or waived and any such acceleration has been rescinded or such Senior Indebtedness has been paid in full in cash.

The Subordinated Indenture will not limit the amount of Senior Indebtedness that we may incur.

No Individual Liability of Directors, Officers, Employees or Stockholders

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

Description of Capital Stock

The following description of our capital stock summarizes the material terms and provisions of the capital stock that we may offer under this prospectus, is not complete and is qualified in its entirety by reference to our articles of incorporation and bylaws, as may be amended from time to time, which have been filed with the SEC as exhibits to the registration statement and each of which is incorporated by reference in this prospectus. In addition, you should be aware that the summary below does not give full effect to the terms of the provisions of statutory or common law.

General

While the terms we have summarized below will apply generally to any future common stock or preferred stock that we may offer, we will describe the specific terms of any series of preferred stock in more detail in the applicable prospectus supplement. If we so indicate in a prospectus supplement, the terms of any preferred stock we offer under that prospectus supplement may differ from the terms we describe below.

Our authorized capital stock consists of 40,000,000 shares of common stock, par value $0.01 per share, and 10,000,000 shares of undesignated preferred stock, par value $0.01 per share. As of April 6, 2017, there were 11,887,513 shares of common stock outstanding and no shares of preferred stock outstanding.

Common Stock

Holders of our common stock are entitled to one vote for each share of common stock held of record for the election of directors and on all matters requiring stockholder action. Holders of our common stock are also entitled to receive, when, as and if declared by the board of directors, out of funds legally available therfor, dividends payable in cash, stocks or otherwise. Upon our liquidation, dissolution or winding up, whether voluntary or involuntary, holders of our common stock are entitled to share ratably in our net assets legally available after the payment of all our debts and other liabilities, subject to the preferential rights of any preferred stock then outstanding. Holders of our common stock have no subscription, preemptive, 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. Holders of our common stock have the exclusive right to vote for the election of directors and for all other purposes excepted as provided by law or by resolution(s) adopted by our board of directors providing for the issuance of any series of preferred stock. With respect to any action taken by the stockholders as to any matter, the affirmative vote of the holders of a majority of stock entitled to vote and represented in person or by proxy at a meeting of the stockholders at which quorum is present shall be sufficient to affirm, ratify or consent to such action.

Listing

Our common stock is listed on the NYSE under the symbol “KMG.” On April 6, 2017 the closing price of our common stock, as reported on the NYSE, was $44.81 per share. As of the close of business on April 6, 2017, there were approximately 374 stockholders of record of our common stock.

Transfer Agent and Registrar

Broadridge Corporate Issuer Solutions, Inc. acts as the transfer agent and registrar for our common stock. The transfer agent and registrar’s address is P.O. Box 1342, Brentwood, New York 11717.

Preferred Stock

Our preferred stock may be issued from time to time in one or more series, and shares of each series will have such designations, powers, preferences, rights, qualifications, limitations, and restrictions as may be fixed by our board of directors in the resolution(s) authorizing the issuance of that particular series. In designating any series of preferred stock, our board of directors has the authority, without further action by the holders of our common stock, to fix the voting rights, dividend rate, conversion rights, rights and terms of redemption (including any sinking fund provisions), and the liquidation preferences of that series of preferred stock.

Our board of directors will make any determination to issue such shares based on its judgment as to our best interests and the best interests of our stockholders.

We will incorporate by reference as an exhibit to the registration statement, which includes this prospectus, the form of any certificate of designations that describes the terms of the series of preferred stock we are offering. This description and the applicable prospectus supplement will include:

•

the title and stated value;

•

the number of shares authorized;

•

the liquidation preference per share;

•

the purchase price;

•

the dividend rate, period and payment date, and method of calculation for dividends;

•

whether dividends will be cumulative or non-cumulative and, if cumulative, the date from which dividends will accumulate;

•

the procedures for any auction and remarketing, if any;

•

the provisions for a sinking fund, if any;

•

the provisions for redemption or repurchase, if applicable, and any restrictions on our ability to exercise those redemption and repurchase rights;

•

any listing of the preferred stock on any securities exchange or market;

any limitations on issuance of any class or series of preferred stock ranking senior to or on a parity with the series of preferred stock as to dividend rights and rights if we liquidate, dissolve or wind up our affairs; and

•

any other specific terms, preferences, rights or limitations of, or restrictions on, the preferred stock.

When we issue shares of preferred stock under this prospectus, the shares will fully be paid and nonassessable and will not have, or be subject to, any preemptive or similar rights.

We do not have any shares of preferred stock outstanding as of the date hereof.

Registration Rights

As of the date hereof, no holder of our common stock is eligible to exercise any contractual rights to require us to register any shares of such holder under the Securities Act.

Provisions of our Articles of Incorporation and Bylaws

Our amended and restated articles of incorporation and amended and restated bylaws include a number of provisions that may have the effect of encouraging persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with our board of directors rather than pursue non-negotiated takeover attempts. These provisions include the items described below.

Authorized shares

Our authorized but unissued shares of common 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. Our board of directors has the authority, without further stockholder approval, to provide for the issuance of up to 10,000,000 shares of preferred stock in one or more series and to determine the dividend rights, the conversion rights, voting rights, rights and terms of redemption, liquidation, preferences, the number of shares constituting any such series and the designation of such series. Since the board of directors has the power to establish the preferences and rights of such series, it may afford the holders of any preferred stock preferences, powers and rights, including voting rights, senior to the rights of the holders of our common stock. The existence of authorized but unissued shares could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Board composition and filling vacancies

In accordance with our amended and restated bylaws, the number of directors which shall constitute our board of directors shall not be less than five. The number of directors shall from time to time be fixed and determined by our board of directors, and the directors shall be elected as the annual meeting of stockholders. Our amended and restated bylaws also provide that any director may be removed either for or without cause at any special meeting of stockholders and held for such purpose. Furthermore, any vacancy on our board of directors may be filled by a majority of the remaining directors, if any, though less than a quorum of our board of directors. If a vacancy occurs on our board of directors and no other directors exist to elect someone to fill such vacancy, such vacancy shall be filled by election at a special meeting of stockholders.

Written consent of stockholders

Our amended and restated bylaws provide that any action required or permitted to be taken at a stockholder meeting may be taken without a meeting, without prior notice, and without a vote if a consent in writing is signed by all of the stockholders entitled to vote.

Meetings of stockholders

Our amended and restated bylaws provide that a special meeting of the stockholders may be called by our president or chairman and shall be called by our president or secretary at the written request of a majority of our board of directors or at the written request of a majority of stockholders entitled to vote. A request for a special meeting shall state the purpose or purposes of the proposed meeting, and business transacted at any special meeting of stockholders shall be limited to the purposes stated in the notice. Our amended and restated bylaws limit the business that may be conducted at an annual meeting of stockholders to those matters properly brought before the meeting.

Advance notice requirements

Our 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 before 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 60 calendar days nor more than 90 calendar days prior to the anniversary date of the date on which we first mailed our proxy materials for our immediately preceding annual meeting of stockholders; provided, however, that in the event the annual meeting is called for a date that is not within 30 calendar days of the anniversary date of the date on which the immediately preceding annual meeting of stockolders was called, to be timely, notice by the stockholder must be so received not later than the close of business on the 10th calendar day following the day on which public announcement of the date of the annual meeting is first made. The notice must contain certain information specified in our amended and restated bylaws.

Amendment to bylaws and articles of incorporation

Our amended and restated bylaws may be altered, amended or repealed or new bylaws may be adopted by a majority of our board of directors at any regular or special meeting. Our amended and restated articles of incorporation provide that we reserve the right to amend, alter, change or repeal any provision contained in our amended and restated articles of incorporation.

Blank check preferred stock

Our amended and restated articles of incorporation authorizes 10,000,000 shares of preferred stock. The existence of authorized but unissued shares of preferred stock may enable our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise. For example, if in the due exercise of its fiduciary obligations, our board of directors were to determine that a takeover proposal is not in the best interests of us or our stockholders, our board of directors could cause shares of preferred stock to be issued without stockholder approval in one or more private offerings or other transactions that might dilute the voting or other rights of the proposed acquirer or insurgent stockholder or stockholder group. In this regard, our amended and restated articles of incorporation grants our board of directors’ broad power to establish the rights and preferences of authorized and unissued shares of preferred stock. The issuance of shares of preferred stock could decrease the amount of earnings and assets available for distribution to holders of shares of common stock. The issuance may also adversely affect the rights and powers, including voting rights, of these holders and may have the effect of delaying, deterring or preventing a change in control of us.

Anti-takeover Effects of the Texas Business Organizations Code

Certain provisions of Texas law, our restated and amended articles of incorporation and our restated and amended bylaws are intended to enhance the likelihood of continuity and stability in our board of directors and its policies, but might have the effect of delaying or preventing a change in control or takeover attempt and may make more difficult the removal of incumbent management that a shareholder might consider in his or her best interest, including attempts that might result in a premium over the market price for our common stock.

Texas Business Organizations Code. We are subject to the provisions of Title 2, Chapter 21, Subchapter M of the Texas Business Organizations Code (the “Texas Business Combination Law”). That law provides that a Texas corporation may not engage in specified types of business combinations, including mergers, consolidations and asset sales, with a person, or an affiliate or associate of that person, who is an “affiliated shareholder.” An “affiliated shareholder” is generally defined as the holder of 20% or more of the corporation’s voting shares, for a period of three years from the date that person became an affiliated shareholder. The law’s prohibitions do not apply if:

•

the business combination or the acquisition of shares by the affiliated shareholder was approved by the board of directors of the corporation before the affiliated shareholder became an affiliated shareholder; or

•

the business combination was approved by the affirmative vote of the holders of at least two-thirds of the outstanding voting shares of the corporation not beneficially owned by the affiliated shareholder, at a meeting of shareholders called for that purpose, not less than six months after the affiliated shareholder became an affiliated shareholder.

Because we have more than 100 shareholders, we are considered an “issuing public corporation” for purposes of this law. The Texas Business Combination Law does not apply to the following:

•

the business combination of an issuing public corporation: where the corporation’s original charter or bylaws contain a provision expressly electing not to be governed by the Texas Business Combination Law; or that adopts an amendment to its charter or bylaws, by the affirmative vote of the holders, other than affiliated shareholders, of at least two-thirds of the outstanding voting shares of the corporation, expressly electing not to be governed by the Texas Business Combination Law and so long as the amendment does not take effect for 18 months following the date of the vote and does not apply to a business combination with an affiliated shareholder who became affiliated on or before the effective date of the amendment;

•

a business combination of an issuing public corporation with an affiliated shareholder that became an affiliated shareholder inadvertently, if the affiliated shareholder divests itself, as soon as possible, of enough shares to no longer be an affiliated shareholder and would not at any time within the three-year period preceding the announcement of the business combination have been an affiliated shareholder but for the inadvertent acquisition;

•

a business combination with an affiliated shareholder who became an affiliated shareholder through a transfer of shares by will or intestacy and continuously was an affiliated shareholder until the announcement date of the business combination; and

•

a business combination of a corporation with its wholly owned Texas subsidiary if the subsidiary is not an affiliate or associate of the affiliated shareholder other than by reason of the affiliated shareholder’s beneficial ownership of voting shares of the corporation.

Neither our restated and amended articles of incorporation nor our restated and amended bylaws contain any provision expressly providing that we will not be subject to the Texas Business Combination Law. The Texas Business Combination Law may have the effect of inhibiting a non-negotiated merger or other business combination involving our company, even if that event would be beneficial to our shareholders.

Description of Depositary Shares

General

We may offer fractional shares of preferred stock, rather than full shares of preferred stock. If we decide to offer fractional shares of preferred stock, we will issue receipts for depositary shares. Each depositary share will represent a fraction of a share of a particular series of preferred stock. The prospectus supplement will indicate that fraction. The shares of preferred stock represented by depositary shares will be deposited under a depositary agreement between us and a bank or trust company that meets certain requirements and is selected by us (the “Bank Depositary”). Each owner of a depositary share will be entitled to all the rights and preferences of the preferred stock represented by the depositary share. The depositary shares will be evidenced by depositary receipts issued pursuant to the depositary agreement. Depositary receipts will be distributed to those persons purchasing the fractional shares of preferred stock in accordance with the terms of the offering.

We have summarized selected provisions of a depositary agreement and the related depositary receipts. The summary is not complete. The forms of the depositary agreement and the depositary receipts relating to any particular issue of depositary shares will be filed with the SEC via a Current Report on Form 8-K prior to our offering of the depositary shares, and you should read such documents for provisions that may be important to you.

We do not have any depositary shares outstanding as of the date hereof.

Dividends and Other Distributions

If we pay a cash distribution or dividend on a series of preferred stock represented by depositary shares, the Bank Depositary will distribute such dividends to the record holders of such depositary shares. If the distributions are in property other than cash, the Bank Depositary will distribute the property to the record holders of the depositary shares. However, if the Bank Depositary determines that it is not feasible to make the distribution of property, the Bank Depositary may, with our approval, sell such property and distribute the net proceeds from such sale to the record holders of the depositary shares.

Redemption of Depositary Shares

If we redeem a series of preferred stock represented by depositary shares, the Bank Depositary will redeem the depositary shares from the proceeds received by the Bank Depositary in connection with the redemption. The redemption price per depositary share will equal the applicable fraction of the redemption price per share of the preferred stock. If fewer than all the depositary shares are redeemed, the depositary shares to be redeemed will be selected by lot or pro rata as the Bank Depositary may determine.

Voting the Preferred Stock

Upon receipt of notice of any meeting at which the holders of the preferred stock represented by depositary shares are entitled to vote, the Bank Depositary will mail the notice to the record holders of the depositary shares relating to such preferred stock. Each record holder of these depositary shares on the record date (which will be the same date as the record date for the preferred stock) may instruct the Bank Depositary as to how to vote the preferred stock represented by such holder’s depositary shares. The Bank Depositary will endeavor, insofar as practicable, to vote the amount of the preferred stock represented by such depositary shares in accordance with such instructions, and we will take all action which the Bank Depositary deems necessary in order to enable the Bank Depositary to do so. The Bank Depositary will abstain from voting shares of the preferred stock to the extent it does not receive specific instructions from the holders of depositary shares representing such preferred stock.

Amendment and Termination of the Depositary Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the depositary agreement may be amended by agreement between the Bank Depositary and us. However, any amendment that materially and adversely alters the rights of the holders of depositary shares will not be effective unless such amendment has been approved by the holders of at least a majority of the depositary shares then outstanding. The depositary agreement may be terminated by the Bank Depositary or us only if (1) all outstanding depositary shares have been redeemed or (2) there has been a final distribution in respect of the preferred stock in connection with any liquidation, dissolution or winding up of our company and such distribution has been distributed to the holders of depositary receipts.

Charges of Bank Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay charges of the Bank Depositary in connection with the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary receipts will pay other transfer and other taxes and governmental charges and any other charges, including a fee for the withdrawal of shares of preferred stock upon surrender of depositary receipts, as are expressly provided in the depositary agreement to be for their accounts.

Withdrawal of Preferred Stock

Upon surrender of depositary receipts at the principal office of the Bank Depositary, subject to the terms of the depositary agreement, the owner of the depositary shares may demand delivery of the number of whole shares of preferred stock and all money and other property, if any, represented by those depositary shares. Partial shares of preferred stock will not be issued. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock to be withdrawn, the Bank Depositary will deliver to such holder at the same time a new depositary receipt evidencing the excess number of depositary shares. Holders of preferred stock thus withdrawn may not thereafter deposit those shares under the depositary agreement or receive depositary receipts evidencing depositary shares therefor.

Miscellaneous

The Bank Depositary will forward to holders of depositary receipts all reports and communications from us that are delivered to the Bank Depositary and that we are required to furnish to the holders of the preferred stock.

Neither the Bank Depositary nor we will be liable if we are prevented or delayed by law or any circumstance beyond our control in performing our obligations under the depositary agreement. The obligations of the Bank Depositary and us under the depositary agreement will be limited to performance in good faith of our duties thereunder, and neither of us will be obligated to prosecute to defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished. Further, both of us may rely upon written advice of counsel or accountants, or upon information provided by persons presenting preferred stock for deposit, holders of depositary receipts or other persons believed to be competent and on documents believed to be genuine.

Resignation and Removal of Bank Depositary

The Bank Depositary may resign at any time by delivering to us notice of its election to do so, and we may at any time remove the Bank Depositary. Any such resignation or removal will take effect upon the appointment of a successor Bank Depositary and its acceptance of such appointment. Such successor Bank Depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50 million.

Description of Warrants

The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the warrants that we may offer under this prospectus and the related warrant agreements and warrant certificates. While the terms summarized below will apply generally to any warrants that we may offer, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement. If we indicate in the prospectus supplement, the terms of any warrants offered under that prospectus supplement may differ from the terms described below. Specific warrant agreements will contain additional important terms and provisions and will be incorporated by reference as an exhibit to the registration statement, which includes this prospectus.

We do not have any warrants outstanding as of the date hereof.

General

We may issue warrants for the purchase of common stock and/or preferred stock in one or more series. We may issue warrants independently or together with common stock and/or preferred stock, and the warrants may be attached to or separate from these securities.

We will evidence each series of warrants by warrant certificates that we will issue under a separate warrant agreement. We may enter into the warrant agreement with a warrant agent. We may also choose to act as our own warrant agent. We will indicate the name and address of the warrant agent in the applicable prospectus supplement relating to a particular series of warrants.

We will describe in the applicable prospectus supplement the terms of the series of warrants, including:

•

the offering price and aggregate number of warrants offered;

•

the currency for which the warrants may be purchased;

•

if applicable, the designation and terms of the securities with which the warrants are issued and the number of warrants issued with each such security or each principal amount of such security;

•

if applicable, the date on and after which the warrants and the related securities will be separately transferable;

•

in the case of warrants to purchase common stock or preferred stock, the number of shares of common stock or preferred stock, as the case may be, purchasable upon the exercise of one warrant and the price at which these shares may be purchased upon such exercise;

•

the effect of any merger, consolidation, sale or other disposition of our business on the warrant agreement and the warrants;

•

the terms of any rights to redeem or call the warrants;

•

any provisions for changes to or adjustments in the exercise price or number of securities issuable upon exercise of the warrants;

•

anti-dilution provisions of the warrants, if any;

•

the periods during which, and places at which, the warrants are exercisable;

•

the manner of exercise of the warrants, including any cashless exercise rights;

•

the dates on which the right to exercise the warrants will commence and expire;

•

the manner in which the warrant agreement and warrants may be modified;

•

federal income tax consequences of holding or exercising the warrants;

•

any securities exchange or quotation system on which the warrants or any securities deliverable upon exercise of the warrants may be listed or quoted;

•

the terms of the securities issuable upon exercise of the warrants; and

•

any other specific terms, preferences, rights or limitations of or restrictions on the warrants.

Before exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including, in the case of warrants to purchase common stock or preferred stock, the right to receive dividends, if any, or, payments upon our liquidation, dissolution or winding up or to exercise voting rights, if any.

Exercise of Warrants

Each warrant will entitle the holder to purchase the securities that we specify in the applicable prospectus supplement at the exercise price that we describe in the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to 5:00 P.M. Eastern Time, the close of business, on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Holders of the warrants may exercise the warrants by delivering the warrant certificate representing the warrants to be exercised together with specified information, and paying the required exercise price by the methods provided in the applicable prospectus supplement. We will set forth on the reverse side of the warrant certificate, and in the applicable prospectus supplement, the information that the holder of the warrant will be required to deliver to the warrant agent.

Upon receipt of the required payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants represented by the warrant certificate are exercised, then we will issue a new warrant certificate for the remaining amount of warrants.

Enforceability of Rights By Holders of Warrants

Any warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action the holder’s right to exercise, and receive the securities purchasable upon exercise of, its warrants in accordance with their terms.

Warrant Agreement Will Not Be Qualified Under Trust Indenture Act

No warrant agreement will be qualified as an indenture, and no warrant agent will be required to qualify as a trustee, under the TIA. Therefore, holders of warrants issued under a warrant agreement will not have the protection of the TIA with respect to their warrants.

PLAN OF DISTRIBUTION

We may sell the securities offered by this prospectus from time to time in one or more transactions, including, without limitation:

•

to or through underwriters, brokers or dealers (acting as agent or principal);

•

directly to one or more other purchasers;

•

upon the exercise of rights distributed or issued to our security holders;

•

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

•

in “at the market” offerings within the meanings of Rule 415(a)(4) under the Securities Act of 1933 or through a market maker or into an existing market, on an exchange, or otherwise;

•

directly to purchasers, through a specific bidding or auction process, on a negotiated basis or otherwise;

•

through agents on a best-efforts basis;

•

through any other method permitted pursuant to applicable law; or

•

otherwise through a combination of any of the above methods of sale.

In addition, we may enter into option, share lending or other types of transactions that require us to deliver shares of common stock to an underwriter, broker or dealer, who will then resell or transfer the shares of common stock under this prospectus. We may also enter into hedging transactions with respect to our securities. For example, we may:

•

enter into transactions involving short sales of the shares of common stock by underwriters, brokers or dealers;

•

sell shares of common stock short and deliver the shares to close out short positions;

•

enter into option or other types of transactions that require us to deliver shares of common stock to an underwriter, broker or dealer, who will then resell or transfer the shares of common stock under this prospectus; or

•

loan or pledge the shares of common stock to an underwriter, broker or dealer, who may sell the loaned shares or, in the event of default, sell the pledged shares.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

If we use any underwriter, we will provide a prospectus supplement that will name any underwriter involved in the offer and sale of the securities. The prospectus supplement will also set forth the terms of the offering, including:

•

the purchase price of the securities and the proceeds we will receive from the sale of the securities;

•

any underwriting discounts and other items constituting underwriters’ compensation;

•

any public offering or purchase price and any discounts or commissions allowed or re-allowed or paid to dealers;

•

any commissions allowed or paid to agents;

•

any securities exchanges on which the securities may be listed;

•

the method of distribution of the securities;

•

the terms of any agreement, arrangement or understanding entered into with the underwriters, brokers or dealers; and

•

any other information we think is important.

If underwriters or dealers are used in the sale, the securities will be acquired by the underwriters or dealers for their own account. The securities may be sold from time to time by us in one or more transactions:

•

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

•

at market prices prevailing at the time of sale;

•

at prices related to such prevailing market prices;

•

at varying prices determined at the time of sale; or

•

at negotiated prices.

Such sales may be effected:

•

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 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, in which the same broker acts as an agent on both sides of the trade;

•

through the writing of options; or

•

through other types of transactions.

General

Any public offering price and any discounts, commissions, concessions or other items constituting compensation allowed or reallowed or paid to underwriters, dealers, agents or remarketing firms may be changed from time to time. Underwriters, dealers, agents and remarketing firms that participate in the distribution of the offered securities may be “underwriters” as defined in the Securities Act. Any discounts or commissions they receive from us and any profits they receive on the resale of the offered securities may be treated as underwriting discounts and commissions under the Securities Act. We will identify any underwriters, agents or dealers and describe their commissions, fees or discounts in the applicable prospectus supplement or pricing supplement, as the case may be. In compliance with the guidelines of the Financial Industry Regulatory Authority (“FINRA”), the maximum discount or commission to be received by a FINRA member or independent broker-dealer may not exceed 8% of the aggregate amount of the securities offered pursuant to this prospectus and any applicable prospectus supplement.

At-the-Market Offerings

If we reach an agreement with an underwriter or agent on a placement, including the number and types of securities to be offered in the placement and any minimum price below which sales may not be made, such underwriter or agent would agree to use its commercially reasonable efforts, consistent with its normal trading and sales practices, to try to sell such securities on such terms. An underwriter or agent could make sales in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act, sales made directly on the NYSE, the existing trading market for our common stock, or sales made to or through a market maker other than on an exchange. The name of any such underwriter or agent involved in the offer and sale of the securities, the amounts underwritten, and the nature of its obligations to take the securities will be described in the applicable prospectus supplement.

Underwriters and Agents

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

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

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

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

Dealers

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

Direct Sales

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

Institutional Purchasers

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

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

Indemnification; Other Relationships

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

Market-Making, Stabilization and Other Transactions

There is currently no market for the offered preferred stock. If the offered preferred stock is traded after its initial issuance, it may trade at a discount from its initial offering price, depending upon prevailing interest rates, the market for similar securities and other factors. While it is possible that an underwriter could inform us that it intends to make a market in the offered preferred stock, such underwriter would not be obligated to do so, and any such market-making could be discontinued at any time without notice. Therefore, no assurance is given as to whether an active trading market will develop for the offered preferred stock. If we seek to list the preferred stock on any exchange or quotation system, any such listing with respect to any particular preferred stock will be described in the applicable prospectus supplement or pricing supplement, as the case may be.

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

Some of the underwriters, dealers or agents used by us in any offering of securities under this prospectus may be customers of, engage in transactions with, and perform services for us or affiliates of ours in the ordinary course of business. Any underwriters to which offered securities are sold by us for public offering and sale may make a market in such securities, but those underwriters will not be obligated to do so and may discontinue any market making at any time.

The anticipated date of delivery of the securities offered by this prospectus will be described in the applicable prospectus supplement relating to the offering.

No FINRA member may participate in any offering of securities made under this prospectus if such member has a conflict of interest under FINRA Rule 5121, including if 5% or more of the net proceeds, not including

underwriting compensation, of any offering of securities made under this prospectus will be received by a FINRA member participating in the offering or affiliates or associated persons of such FINRA members, unless a qualified independent underwriter has participated in the offering or the offering otherwise complies with FINRA Rule 5121.

To comply with the securities laws of some states, if applicable, the securities may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the securities may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

LEGAL MATTERS

The validity of the securities offered by this prospectus has been passed upon for us by Haynes and Boone, LLP, Houston, Texas, counsel to KMG Chemicals, Inc. Certain legal matters will be passed upon for any agents or underwriters by counsel for such agents or underwriters identified in the applicable prospectus supplement.

Item 15.

Indemnification of Directors and Officers.

We are a corporation incorporated under the laws of the State of Texas. Section 7.001 of the Texas Business Organizations Code, or the TBOC, permits a Texas corporation to limit the personal liability of its directors to such corporation or its shareholders for monetary damages for any act or omission in a director’s capacity as director, except for liability for any of the following:

(i)

A breach of the director’s duty of loyalty to the corporation or its shareholders;

(ii)

An act or omission not in good faith that constitutes a breach of duty of the director to the corporation or an act or omission that involves intentional misconduct or knowing violation of law;

(iii)

A transaction from which the director received an improper benefit, regardless of whether the benefit resulted from an action taken within the scope of the director’s duties; or

(iv)

An act or omission for which the liability of a director is expressly provided by an applicable statute.

Under Sections 8.101, 8.102 and 8.103 of the TBOC, subject to the procedures and limitations stated therein, a Texas corporation may indemnify a director who was, is or is threatened to be made a respondent in a proceeding against a judgment and reasonable expenses actually incurred by the person in connection with the proceeding if it is determined that the person seeking indemnification:

(i)

acted in good faith;

(ii)

reasonably believed (A) in the case of conduct in his or her official capacity, that his or her conduct was in or was not opposed to the corporation’s best interests, or (B) in any other case, that his or her conduct was not opposed to the corporation’s best interests; and

(iii)

in the case of a criminal proceeding, did not have a reasonable cause to believe his or her conduct was unlawful.

Under Section 8.105 of the TBOC, a Texas corporation may indemnify an officer as provided by its governing documents, by action of its board of directors, by action of its shareholders, by contract or by common law.

II-1

Sections 8.051 and 8.105 of the TBOC require a Texas corporation to indemnify a director, former director or officer against reasonable expenses actually incurred by the director, former director or officer in connection with a proceeding in which the director, former director or officer is a respondent because the director, former director or officer is or was in that position if the director, former director or officer has been wholly successful, on the merits or otherwise, in the defense of the proceeding.

The TBOC prohibits a Texas corporation from indemnifying a director in respect of a proceeding in which the director is found liable to the corporation or is found liable because a personal benefit was improperly received by him or her, other than for reasonable expenses actually incurred by him or her in connection with the proceeding, not including a judgment, penalty, fine or tax. The TBOC prohibits a Texas corporation entirely from indemnifying a director in respect of any such proceeding in which the director is found liable for willful or intentional misconduct in the performance of his or her duties to the corporation, breach of the duty of loyalty to the corporation or an act or omission not committed in good faith that constitutes a breach of a duty owed by the director to the corporation.

Under Sections 8.052 and 8.105 of the TBOC, a court may order a Texas corporation to indemnify a director, former director or officer if the court determines that the director, former director or officer is fairly and reasonably entitled to indemnification in view of all the relevant circumstances. If, however, the director, former director or officer is found liable to the corporation or is found liable on the basis that a personal benefit was improperly received by him or her, the indemnification will be limited to reasonable expenses actually incurred by him or her in connection with the proceeding.

Article Nine of our Restated and Amended Articles of Incorporation provides that to the fullest extent permitted by Texas law, our directors will have no personal liability to us or our shareholders for any acts or omissions in the director’s performance of his or her duties as a director. Article Nine further provides that if Texas law is amended to authorize further elimination of the personal liability of directors for or with respect to any acts or omissions in the performance of their duties as directors, then the liability of a director shall be eliminated to the fullest extent permitted by Texas law, as so amended. Any repeal or modification of Article Nine by our shareholders will not adversely affect any right or protection of a director existing immediately prior to such repeal or modification.

Article 9 of our Amended and Restated Bylaws provide that we must indemnify our directors and officers to the fullest extent permitted by Texas law. Our Amended and Restated Bylaws further provide that we must pay or reimburse reasonable expenses incurred by one of our directors or officers who was, is or is threatened to be made a named defendant or respondent in a proceeding to the maximum extent permitted under Texas law.

Item 16.

Exhibits.

A list of exhibits filed with this registration statement on Form S-3 is set forth on the Exhibit Index and is incorporated herein by reference.

Item 17.

Undertakings.

The undersigned registrant hereby undertakes:

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

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement.

II-2

Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(l)(i), (a)(l)(ii) and (a)(l)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Securities and Exchange Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement;

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

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

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

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

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

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

II-3

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

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

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

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

(b) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and

(c) To supplement the prospectus, after the expiration of the subscription period to set forth the results of the subscription offer, the transactions by the underwriters during the subscription period, the amount of unsubscribed securities to be purchased by the underwriters, and the terms of any subsequent reoffering thereof. If any public offering by the underwriters is to be made on terms differing from those set forth on the cover page of the prospectus, a post-effective amendment will be filed to set forth the terms of such offering.

(d) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
