    <div style="text-align: left; text-indent: 36pt;"><font style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-style: italic;">You should carefully consider the risks described below and in our Annual Report on Form&#160;10-K for the
        fiscal&#160;year ended December&#160;31, 2018, which is incorporated by reference into this prospectus supplement, before making a decision to invest in our notes.&#160; The risks and uncertainties described below and in the documents incorporated by reference
        are not the only ones facing our Company.&#160; Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also materially adversely affect our business and operations.</font></div>
    <div>&#160;</div>
    <div style="text-align: left; text-indent: 36pt;"><font style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-style: italic;">If any of the matters included in the following risks were to occur, our business, financial condition,
        results of operations, cash flows or prospects could be materially adversely affected.&#160; In such case, you may lose all or part of your original investment.</font></div>
    <div>&#160;</div>
    <div style="text-align: left;"><font style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-weight: bold;">Our outstanding debt may impair our financial and operating flexibility.</font></div>
    <div>&#160;</div>
    <div style="text-align: left; text-indent: 36pt;"><font style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">As of December 31, 2018, after giving effect to this offering and the anticipated use of the net proceeds therefrom (as if
        all of the foregoing had occurred on that date), Quest Diagnostics would have had approximately $3,930 million of debt outstanding, with $750&#160;million of available capacity under our senior unsecured revolving credit facility, which matures in March
        2023 and $529 million of available capacity under our secured receivables credit facility, and our subsidiaries would have had debt outstanding of $34&#160;million.&#160; Except for operating leases, we do not have any off-balance sheet financing
        arrangements in place or available.&#160; See Note&#160;14 to the consolidated financial statements included in our Annual Report on Form&#160;10-K for the&#160;year ended December&#160;31, 2018 for further details related to our outstanding debt.&#160; See Note&#160;15 to the
        consolidated financial statements included in our Annual Report on Form&#160;10-K for the&#160;year ended December&#160;31, 2018 for further details related to our use of derivative financial instruments to manage our exposure to market risks for changes in
        interest rates.&#160; Our debt agreements contain various restrictive covenants.&#160; These restrictions could limit our ability to use operating cash flow in other areas of our business because we must use a portion of these funds to make principal and
        interest payments on our debt.&#160; We have obtained ratings on our debt from S&amp;P Global Ratings, Moody&#8217;s Investors Service and Fitch Ratings.&#160; There can be no assurance that any rating so assigned will remain for any given period of time or that a
        rating will not be lowered or withdrawn entirely by a rating agency if in that rating agency&#8217;s judgment future circumstances relating to the basis of the rating, such as adverse changes in our Company or our industry, so warrant.&#160; If any of our
        debt ratings are lowered, the borrowing costs on our senior unsecured revolving credit facility and secured receivables facility could increase.&#160; Changes in our credit ratings, however, do not require repayment or acceleration of any of our debt.</font></div>
    <div>&#160;</div>
    <div style="text-align: left; text-indent: 36pt;"><font style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">We or our subsidiaries may incur additional indebtedness in the future.&#160; The notes offered hereby do not limit our ability,
        or the ability of any of our subsidiaries that may in the future guarantee the notes, to incur unsecured indebtedness.&#160; Our ability to make principal and interest payments will depend on our ability to generate cash in the future.&#160; If we incur
        additional debt, a greater portion of our cash flows may be needed to satisfy our debt service obligations and if we do not generate sufficient cash to meet our debt service requirements, we may need to seek additional financing.&#160; In that case, it
        may be more difficult, or we may be unable, to obtain financing on terms that are acceptable to us.&#160; As a result, we would be more vulnerable to general adverse economic, industry and capital markets conditions as well as the other risks associated
        with indebtedness.</font></div>
    <div>&#160;</div>
    <div style="text-align: left;"><font style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-weight: bold;">Secured indebtedness incurred by Quest Diagnostics will be effectively, and existing and future obligations of our
        subsidiaries (including preferred stock) will be structurally, senior to the notes.</font></div>
    <div>&#160;</div>
    <div style="text-align: left; text-indent: 36pt;"><font style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">The notes are our senior unsecured obligations and therefore will be effectively subordinated to our secured obligations to
        the extent of the value of the assets securing such obligations.&#160; The notes will also be structurally subordinated to any existing and future indebtedness and other obligations of our subsidiaries.&#160; Our subsidiaries are not guarantors of the notes;
        however, under the terms of the indenture governing the notes, certain of our domestic subsidiaries may be required to become subsidiary guarantors in the future if they incur or assume any Indebtedness, subject to exceptions set forth in the
        indenture governing the notes, or guarantee any Indebtedness of our Company when the amount of such Indebtedness, together with any other outstanding Indebtedness of our Company guaranteed by our subsidiaries that do not guarantee the notes,
        exceeds $50&#160;million in the aggregate at any time.&#160; See &#8220;Description of Notes&#8212;Future Subsidiary Guarantors.&#8221;&#160; The indenture governing the notes does not limit the amount of indebtedness that we can incur, but does limit the amount of indebtedness
        our subsidiaries who do not provide subsidiary guarantees are permitted to incur (as described below).&#160; In addition, the indenture governing the notes limits the amount of secured indebtedness Quest Diagnostics and its restricted subsidiaries may
        incur pursuant to the covenant described under the heading &#8220;Description of Notes&#8212;Limitation on Liens.&#8221;&#160; This covenant is subject to important exceptions described under such heading.&#160; As of December 31, 2018, after giving effect to this offering
        and the anticipated use of the net proceeds therefrom (as if all of the foregoing had occurred on that date), Quest Diagnostics would have had outstanding $37 million of secured debt.</font></div>
    <div>&#160;</div>
    <div style="text-align: left; text-indent: 36pt;"><font style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">We conduct our operations through subsidiaries, which generate a substantial portion of our operating income and cash flow.&#160;
        As a result, distributions or advances from our subsidiaries are a major source of funds necessary to meet our debt service and other obligations.&#160; Contractual provisions, laws or regulations, as well as any subsidiary&#8217;s condition and operating
        requirements, may limit our ability to obtain cash required to pay our debt service and other obligations.&#160; The notes will be structurally subordinated to all existing and future obligations of our subsidiaries, including claims with respect to
        trade payables.&#160; As of December 31, 2018, after giving effect to this offering and the anticipated use of the net proceeds therefrom (as if all of the foregoing had occurred on that date), our subsidiaries would have had debt outstanding of $34
        million, all of which would have been secured.</font></div>

      <div style="text-align: left; line-height: 1.25; font-family: 'Times New Roman', Times, serif; font-size: 10pt;">The notes are new issues of securities for which there currently are no trading markets. Although the underwriters have informed us that
        they intend to make markets in the notes, they are not obligated to do so, and any such market-making activities may be discontinued at any time without notice.&#160; As a result, we cannot provide any assurances that trading markets for the notes will
        ever develop or be maintained. Further, we can make no assurances as to the liquidity of any markets that may develop for the notes, your ability to sell your notes or the prices at which you will be able to sell your notes. Future trading prices
        of the notes will depend on many factors, including prevailing interest rates, our financial condition and results of operations, the condition of the industry in which we operate generally, the then-current ratings assigned to the notes and the
        market for similar securities. Accordingly, you may be required to bear the financial risk of an investment in the notes for an indefinite period of time. We do not intend to apply for listing or quotation of the notes on any securities exchange or
        automated quotation system.</div>

        Clearstream Luxembourg, Euroclear, banks, brokers, dealers and trust companies (collectively, the &#8220;indirect participants&#8221;) that clear through or maintain a custodial relationship with a participant, either directly or indirectly.&#160; Investors who are

        Clearstream Luxembourg is incorporated under the laws of Luxembourg as a professional depositary.&#160; Clearstream Luxembourg holds securities for its participating organizations (&#8220;Clearstream Luxembourg Participants&#8221;) and facilitates the clearance and
        settlement of securities transactions between Clearstream Luxembourg Participants through electronic book-entry changes in accounts of Clearstream Luxembourg Participants, thereby eliminating the need for physical movement of certificates.&#160;
        Clearstream Luxembourg provides Clearstream Luxembourg Participants with, among other things, services for safekeeping, administration, clearance and establishment of internationally traded securities and securities lending and borrowing.&#160;
        Clearstream Luxembourg interfaces with domestic markets in several countries.&#160; As a professional depositary, Clearstream Luxembourg is subject to regulation by the Luxembourg Monetary Institute.&#160; Clearstream Luxembourg Participants are recognized
        financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, and may include the underwriters.&#160; Indirect access to Clearstream
        Luxembourg is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Luxembourg Participant either directly or indirectly.</font></div>

        eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash.&#160; Euroclear includes various other services, including securities lending and borrowing and interfaces with domestic
        markets in several markets in several countries.&#160; Euroclear is operated by Euroclear Bank S.A./N.V. (the &#8220;Euroclear Operator&#8221;), under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the &#8220;Cooperative&#8221;).&#160; All
        operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative.&#160; The Cooperative establishes policy for Euroclear on
        behalf of Euroclear Participants.&#160; Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters.&#160; Indirect access to Euroclear is

        form.&#160; Accordingly, the ability to transfer beneficial interests in notes represented by a global note to those persons may be limited.&#160; In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of persons who
        hold interests through participants, the ability of a person holding a beneficial interest in a global note to pledge or transfer that interest to persons or entities that do not participate in DTC&#8217;s system, or to otherwise take actions in respect
        of that interest, may be affected by the lack of a physical note in respect of that interest.</font></div>

        considered the sole legal owner or holder of the notes represented by that global note for all purposes of the Notes and the Indenture.&#160; Except as provided below, owners of beneficial interests in a global note (1)&#160;will not be entitled to have the
        Notes represented by that global note registered in their names, (2)&#160;will not receive or be entitled to receive physical delivery of certificated notes, and (3)&#160;will not be considered the owners or holders of the Notes represented by that
        beneficial interest under the Indenture for any purpose, including with respect to the giving of any direction, instruction or approval to the trustee.&#160; Accordingly, each holder owning a beneficial interest in a global note must rely on the
        procedures of DTC and, if that holder is not a participant or an indirect participant, on the procedures of the participant through which that holder owns its interest, to exercise any rights of a holder of Notes under the Indenture or that global
        note.&#160; We understand that under existing industry practice, in the event that we request any action of holders of notes, or a holder that is an owner of a beneficial interest in a global note desires to take any action that DTC, as the holder of
        that global note, is entitled to take, DTC would authorize the participants to take that action and the participants would authorize holders owning through those participants to take that action or would otherwise act upon the instruction of those
        holders.&#160; Neither we nor the Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of notes by DTC, or for maintaining, supervising or reviewing any records of DTC relating to the

        delivery of instructions to Euroclear or Clearstream Luxembourg, as the case may be, by the counterparty in that system in accordance with the rules and procedures and within the established deadlines (Brussels time) of that system.&#160; Euroclear or
        Clearstream Luxembourg, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests

        business&#160;day for Euroclear and Clearstream Luxembourg) immediately following the settlement date of DTC.&#160; DTC has advised us that cash received in Euroclear or Clearstream Luxembourg as a result of sales of interests in a global note by or through
        a Euroclear or Clearstream Luxembourg participant to a participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream Luxembourg cash account only as of the business&#160;day

        thereunder, Internal Revenue Service (&#8220;IRS&#8221;) rulings and pronouncements and judicial decisions now in effect, all of which are subject to change at any time.&#160; Any such change may be applied retroactively in a manner that could adversely affect a
        beneficial owner of the notes.&#160; This discussion does not address alternative minimum tax consequences, U.S. federal estate or gift tax laws, the Medicare tax on net investment income or all of the U.S. federal income tax consequences that may be
        relevant to a beneficial owner of the notes in light of such beneficial owner&#8217;s particular circumstances or to beneficial owners of the notes subject to special rules, such as financial institutions, U.S. expatriates, insurance companies, dealers

        accounts, persons required to accelerate the recognition of any item of gross income with respect to the notes as a result of such income being recognized on an &#8220;applicable financial statement&#8221; (within the meaning of Section 451 of the Code) and
        persons holding the notes as part of a &#8220;straddle,&#8221; &#8220;hedge,&#8221; &#8220;conversion transaction&#8221; or other integrated transaction.&#160; In addition, this discussion is limited to beneficial owners of notes that purchase notes for cash in this offering at a price
        equal to their &#8220;issue price&#8221; within the meaning of Section&#160;1273 of the Code (i.e. the first price at which a substantial amount of the notes is sold to the public for cash), and that hold the notes as &#8220;capital assets&#8221; within the meaning of
        Section&#160;1221 of the Code (generally, property held for investment).&#160; Moreover, the effect of any applicable state, local or foreign tax laws, and any part of U.S. federal tax law other than law pertaining to income taxation, is not discussed in

        prior to their stated maturity.&#160; We intend to take the position that these provisions will not cause the notes to be subject to the contingent payment debt instrument rules of applicable U.S. Treasury Regulations (the &#8220;CPDI Rules&#8221;).&#160; Our position
        is binding on a holder, unless the holder discloses in the proper manner to the IRS that it is taking a different position.&#160; Our position is not, however, binding on the IRS.&#160; If the IRS successfully challenged our position, the tax consequences of
        owning and disposing of the notes could be materially different than those described herein, including with respect to the character, timing and amount of income, gain or loss recognized.&#160; The remainder of this discussion assumes that the notes are
        not subject to the CPDI Rules, but there can be no assurances in this regard.&#160; Holders are urged to consult their own tax advisors regarding the potential application to the notes of the CPDI Rules and the consequences thereof.</font></div>

        included in gross income) and the U.S. Holder&#8217;s tax basis in the note.&#160; A U.S. Holder&#8217;s tax basis in a note generally will be the price such U.S. Holder paid for the note.&#160; Such gain or loss generally will be a capital gain or loss, and will be a
        long-term capital gain or loss if the U.S. Holder has held the note for more than one&#160;year at the time of the disposition.&#160; Non-corporate U.S. Holders may be eligible for reduced rates of U.S. federal income tax on long-term capital gains.&#160; The

        backup withholding on such payments.&#160; Certain U.S. Holders (including, among others, corporations and certain tax-exempt organizations) generally are exempt from backup withholding, but may be required to certify to their exempt status.&#160; A
        non-exempt U.S. Holder will be subject to backup withholding if such U.S. Holder:</font></div>

        sales proceeds, even if that payment is made outside the United States, if a non-U.S. Holder sells a note through a non-U.S. office of a broker with certain U.S. connections, unless such broker has documentary evidence in its possession of the

        federal withholding tax of 30% on certain types of payments, including payments of U.S. source interest (such as interest on the notes) made to beneficial owners or intermediaries that are (i)&#160;&#8220;foreign financial institutions&#8221; unless they agree to
        collect and disclose to the IRS information regarding their direct and indirect U.S. account holders and comply with certain other requirements&#160; and (ii)&#160;certain non-financial foreign entities unless they satisfy certain information reporting
        requirements regarding their direct and indirect U.S. owners.&#160; Accordingly, the entity through which a U.S. Holder or a Non-U.S. Holder holds its notes will affect the determination of whether such withholding is required.&#160; Foreign financial
        institutions located in jurisdictions that have an intergovernmental agreement in place with the United States with respect to FATCA may be subject to modified rules.</font></div>

        otherwise affect the prices of the notes.&#160; Specifically, the underwriters may over-allot in connection with the offering, creating short positions in the notes for their own account.&#160; In addition, to cover over-allotments or to stabilize the prices
        of the notes, the underwriters may bid for and purchase notes on the open market.&#160; Further, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the notes in the offering, if the
        syndicate repurchases previously distributed notes in transactions to cover syndicate short positions, in stabilization transactions or otherwise.&#160; Any of these activities may stabilize or maintain the market price of the notes above independent
        market levels.&#160; The underwriters are not required to engage in these activities, and may end any of these activities at any time.</font></div>

    <div style="text-align: left; text-indent: 36pt;"><font style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">Prior to the offering, there have been no active markets for the notes.&#160; The underwriters have advised us that certain of the
        underwriters presently intend to make markets in the notes as permitted by applicable laws and regulations.&#160; Such underwriters are not obligated, however, to make the markets in the notes and any such market making may be discontinued at any time
        at the discretion of such underwriters.&#160; Accordingly, no assurance can be given as to the liquidity of, or trading markets for, the notes.&#160; We do not intend to apply for listing of the notes on any securities exchange or for the inclusion of the
        notes in any automated quotation system.</font></div>

    <div style="text-align: left; text-indent: 36pt;"><font style="font-size: 10pt; font-family: 'Times New Roman', Times, serif;">The underwriters also may impose a penalty bid.&#160; This occurs when a particular underwriter repays to the underwriters a
        portion of the underwriting discount received by it because the representatives have repurchased notes sold by or for the account of such underwriter in stabilizing or short-covering transactions.</font></div>

        unless the parties to any such trade expressly agree otherwise.&#160; Accordingly, purchasers who wish to trade notes on the date of pricing or succeeding &#160; &#160; &#160; &#160; &#160;&#160; business days will be required, by virtue of the fact that the notes will settle in
        T+&#160;&#160;&#160; , to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement; such purchasers should also consult their own advisors in this regard.</div>
