RISK FACTORS

In deciding whether to purchase the notes, you should carefully consider the risks described below, which could cause our operating results and financial condition to be materially adversely affected, as well as other information and data included in or incorporated by reference into this prospectus supplement, including the “Risk Factors” beginning on page 15 of our annual report on Form 10-K for the year ended December 31, 2018.

Risks Relating to this Offering

Our indebtedness could affect our financial health and make it difficult for us to fulfill our obligations under the notes.

As of December 31, 2018, on an as adjusted basis after giving effect to this offering and the use of proceeds therefrom, we would have had total consolidated indebtedness of approximately $2,723.3 million. For more detail regarding our consolidated indebtedness, see “Capitalization.” Our debt could have important consequences for the noteholders. Our ability to make scheduled payments of principal, or to pay the interest or premium, if any, on, or to refinance our indebtedness (including the notes), or to fund capital expenditures, acquisitions and other strategic initiatives will depend on our future performance, which, to a certain extent, is subject to general economic, financial, competitive, regulatory, and other factors that are beyond our control. We cannot assure you that our business will generate sufficient cash flow from operations or that future borrowings will be available under our revolving credit facility or otherwise in an amount sufficient to enable us to service our indebtedness, including the notes, or to fund our other liquidity needs. Furthermore, our increased leverage resulting from this offering could adversely affect our business. In particular, it could increase our vulnerability to sustained, adverse macroeconomic weakness, limit our ability to obtain further financing and limit our ability to pursue certain operational and strategic opportunities.

In addition, the Indenture will not limit our ability to incur additional unsecured debt, including debt that would rank equally with the notes. If we incur any additional debt that ranks equally with the notes, the holders of that debt will be entitled to share ratably with you in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding-up of our company. This may have the effect of reducing the amount of proceeds paid to you.

The notes will be effectively subordinated to all of our existing and future secured debt to the extent of the value of the assets securing such debt.

The notes will be effectively subordinated in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness. In the event of our bankruptcy, liquidation, reorganization or other winding up, our assets that secure debt ranking senior or equal in right of payment to the notes will be available to pay obligations on the notes only after the secured debt has been repaid in full from these assets. There may not be sufficient assets remaining to pay amounts due on any or all of the notes then outstanding.

We are a holding company and substantially all of our operations are conducted by our subsidiaries. None of our subsidiaries will guarantee the notes, and the notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries.

We conduct substantially all of our operations through our subsidiaries, and our subsidiaries generate substantially all of our operating income and cash flow. Our ability to pay our obligations under the notes depends on our ability to obtain cash dividends or other cash payments or obtain loans from our subsidiaries, which are separate and distinct legal entities that will have no obligations to pay any dividends or to lend or advance funds to us. Our subsidiaries may be restricted from paying dividends by contract, including other financing arrangements, charter provisions or applicable legal or regulatory requirements, and their ability to do so may depend on their financial condition and regulatory requirements.

S-10

You will not have any claim as a creditor against any of our subsidiaries, and indebtedness and other liabilities of our subsidiaries will effectively be senior to your claims against them. Consequently, in any insolvency, liquidation, reorganization, dissolution or other winding-up of any of our subsidiaries, creditors of those subsidiaries would be paid before any amounts would be distributed to us, and thus be available to satisfy our obligations under the notes and other claims against us.

We may not be able to service our debt.

Our ability to pay or to refinance our indebtedness, including the notes, will depend upon our future operating performance, which will be affected by general economic, financial, competitive, legislative, regulatory, business and other factors beyond our control.

We cannot assure you that our business will generate sufficient cash flow from operations, that currently anticipated revenue growth and operating improvements will be realized or that future borrowings will be available to us under our credit facility in amounts sufficient to enable us to pay our indebtedness, including the notes, or to fund our other liquidity needs. If we are unable to meet our debt service obligations or fund our other liquidity needs, we could attempt to restructure or refinance our indebtedness or seek additional equity capital. We cannot assure you that we will be able to accomplish those actions on satisfactory terms, if at all.

We may be unable to purchase the notes upon a change of control.

Upon the occurrence of a change of control repurchase event specified in “Description of Notes — Change of Control,” you may require us to purchase your notes at 101% of the principal amount thereof, plus accrued and unpaid interest. If we experience a change of control repurchase event, we cannot assure you that we will have the financial resources to purchase your notes, particularly if that change of control event triggers a similar repurchase requirement for, or results in the acceleration of, our other indebtedness. Our credit facility provides that certain change of control events will constitute a default under the credit facility and could result in the acceleration of our indebtedness.

Restrictive covenants in our Indenture and our credit facility may adversely affect us.

The Indenture, as supplemented to provide for the issuance of the notes offered hereby, will contain various covenants that limit our ability to engage in certain transactions. See “Description of Notes — Certain Covenants.” The Indenture governing our existing senior notes contains substantially similar covenants as will apply to the notes offered hereby.

In addition, our credit facility also contains other and more restrictive covenants. Our credit facility requires us to maintain specified financial ratios and satisfy other financial condition tests. Our ability to meet those financial ratios and tests can be affected by events beyond our control, and we cannot assure you that we will meet those tests. A breach of any of these covenants would result in an event of default under our credit facility. Upon the occurrence of an event of default under our credit facility, the lenders could elect to declare all amounts outstanding under our credit facility to be immediately due and payable and terminate all commitments to extend further credit. If the lenders under our credit facility accelerate the repayment of borrowings, we cannot assure you that we will have sufficient assets to repay amounts outstanding under our credit facility and our other indebtedness, including our existing senior notes and the notes offered hereby.

The Indenture and our credit facility each limits our ability to dispose of operations or to engage in mergers. These restrictions can adversely affect our ability to respond to changing economic and business conditions and may place us at a competitive disadvantage relative to other companies that are subject to fewer or less restrictive limitations.

S-11

Changes in our credit ratings may adversely affect your investment in the notes.

The credit ratings of our indebtedness are an assessment by rating agencies of our ability to pay our debts when due. These ratings are not recommendations to purchase, hold or sell the notes, inasmuch as the ratings do not comment as to market price or suitability for a particular investor, are limited in scope, and do not address all material risks relating to an investment in the notes, but rather reflect only the view of each rating agency at the time the rating is issued. The ratings are based on current information furnished to the ratings agencies by us and information obtained by the ratings agencies from other sources. An explanation of the significance of such rating may be obtained from such rating agency. There can be no assurance that such credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under review for a downgrade, could affect the market value and liquidity of the notes and increase our borrowing costs.

If an active trading market does not develop for the notes, you may be unable to sell your notes at all or at a price that you deem sufficient.

The notes are a new issue of securities for which there currently is no established trading market. Although certain of the underwriters have informed us that they currently intend to make a market in the notes after we complete this offering, they have no obligation to do so and may discontinue making a market in the notes at any time without notice. We cannot provide you with any assurances regarding your ability to sell your notes or the price at which you may be able to sell such notes. The market for the notes may not develop, or the notes may trade at prices that may be higher or lower than the initial offering price for the notes depending on many factors, including prevailing interest rates, our results of operations and financial condition, political and economic developments and the market for similar securities. The notes will not be listed on a national securities exchange. We cannot assure you that a liquid market for the notes will develop or be maintained.

S-12

USE OF PROCEEDS

The net proceeds from this offering are estimated to be approximately $393.95 million after the deduction of the underwriters’ discounts and expenses of the offering payable by us.

We intend to use the net proceeds of this offering for general corporate purposes which includes the repayment of amounts outstanding under our revolving credit facility, which was primarily utilized to repay $250 million aggregate principal amount of senior notes that matured on January 15, 2019.

For further information on terms, including interest rate, of our revolving credit facility, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Financing and Financing Capacity” of our annual report on Form 10-K for the year ended December 31, 2018.

S-13

CAPITALIZATION

The following table sets forth our cash and cash equivalents and capitalization on a consolidated basis as of December 31, 2018 and on an as adjusted basis to reflect the net proceeds for this offering. The table should be read in conjunction with the information under the headings “Summary — Summary Consolidated Financial Data” and “Use of Proceeds” and the consolidated financial statements, including the notes thereto, which are incorporated by reference into this prospectus supplement.

S-14

DESCRIPTION OF NOTES

The following description of notes should be read together with the description set forth in the accompanying prospectus under the heading “Description of Debt Securities and Guarantees of Debt Securities.” In the event that information in this prospectus supplement is inconsistent with information in the accompanying prospectus, you should rely on this prospectus supplement.

The description of notes in this prospectus supplement and the description of debt securities in the accompanying prospectus is only a summary and is intended to be a useful overview of the material provisions of the notes and the Indenture (as defined below), but is not intended to be comprehensive. Since this description of notes is only a summary of the specific terms of the notes offered hereby, you should refer to the Indenture, including the supplemental indenture relating to the notes, for a complete description of our obligations and your rights thereunder.

The notes are a new series of “senior debt securities” as described in the accompanying prospectus. We will issue the notes under the base indenture to be dated March 6, 2019 between Verisk Analytics, Inc. (“Verisk”), as issuer and Wells Fargo Bank, National Association, as trustee, as supplemented by a supplemental indenture to be dated March 6, 2019 relating to the notes offered hereby (as so supplemented, the “Indenture”). The notes offered hereby will not have the benefit of any guarantees. The terms of the notes include those expressly set forth in the Indenture and those made part of the Indenture by referencing the Trust Indenture Act of 1939. We have filed a copy of the form of base indenture as an exhibit to our registration statement filed with the SEC on March 27, 2017 and we will file the Indenture relating to the notes on Form 8-K in connection with this offering, which is incorporated by reference in the registration statement of which the accompanying prospectus is a part.

We may at any time, without notice to or the consent of the holders of the notes, issue an unlimited aggregate principal amount of additional notes having identical terms and conditions as the notes, other than the issue date, issue price and, in some cases, the first interest payment date. We will be permitted to issue such additional notes only if, at the time of such issuance, we are in compliance with the covenants contained in the Indenture. Any additional notes will be part of the same issue as the notes offered hereby and will vote on all matters with the holders of the original notes; provided that if such additional notes are not fungible with the original notes for U.S. federal income tax purposes, such additional notes will have a separate CUSIP number.

When we refer to “we,” “us,” “our” or “the Company” in this section, we refer only to Verisk and not our subsidiaries. Unless otherwise defined in this section below, capitalized terms used in this “Description of Notes” section are defined under “Description of Debt Securities and Guarantees of Debt Securities — Definitions” in the accompanying prospectus.

General

The notes will be our unsecured and unsubordinated indebtedness and will rank equally in right of payment among themselves and with all of our existing and future unsecured and unsubordinated indebtedness. Because the notes will not be secured, they will be effectively subordinated to any future secured indebtedness we incur to the extent of the value of the collateral securing that indebtedness. The notes will not be guaranteed by any of our subsidiaries. As a result, the existing and future liabilities of our subsidiaries will be structurally senior to the notes.

The notes will initially be limited to $400,000,000 aggregate principal amount in this offering. The notes will be issued in the form of one or more fully registered global securities, without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The notes will mature on March 15, 2029 unless earlier redeemed by us, and upon surrender will be repaid at 100% of the principal amount thereof.

The notes will bear interest at the rate of 4.125% per annum from March 6, 2019, or from the most recent interest payment date to which interest has been paid or provided for. Interest on the notes shall be calculated on

S-15

the basis of a 360-day year consisting of twelve 30-day months. Interest on the notes will be payable semi-annually on each March 15 and September 15 (each such date is referred to as an “interest payment date”), beginning on September 15, 2019, until the principal amount has been paid or made available for payment, to holders of notes at the close of business on the March 1 or September 1, as the case may be, immediately preceding the applicable interest payment date (each such date is referred to as a “interest record date”). If any interest payment date, maturity date or redemption date falls on a day that is not a business day, the payment will be made on the next business day and no interest will accrue for the period from and after such interest payment date, maturity date or redemption date.

Optional Redemption

At any time and from time to time prior to December 15, 2028, we may redeem the notes, at our option, in whole or in part, upon not less than 10 nor more than 60 days’ notice at a “make-whole” redemption price equal to the greater of:

in each case, plus accrued and unpaid interest thereon to, but excluding, the date of redemption.

At any time and from time to time on or after December 15, 2028, we may redeem the notes, at our option, in whole or in part, upon not less than 10 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued interest thereon to, but excluding, the date of redemption.

The principal amount of a note remaining outstanding after redemption in part will be $2,000 or an integral multiple of $1,000 in excess thereof. If the date of redemption is on or after an interest record date and on or before the related interest payment date, the accrued and unpaid interest, if any, will be paid to the Person in whose name the applicable note is registered at the close of business on such interest record date, and no additional interest is payable to holders whose notes will be subject to redemption by us.

For purposes of this “— Optional Redemption” section, the following terms have the following meanings:

“Business Day” means any day that is not a Saturday, a Sunday or a day on which banking institutions are not required to be open in the State of New York.

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the notes to be redeemed that would be used, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the notes.

“Comparable Treasury Price” means, with respect to any date of redemption, the Reference Treasury Dealer Quotations for that date of redemption.

“Independent Investment Banker” means the Reference Treasury Dealer appointed by us.

“Reference Treasury Dealer” means each of HSBC Securities (USA) Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated and their respective successors and two other nationally recognized investment banking firms that are primary U.S. Government securities dealers (a “Primary Treasury Dealer”) specified from time to time by us so long as the entity is a primary U.S. Government securities dealer.

S-16

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any date of redemption, the average, as determined by us, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to us by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding that date of redemption, after excluding the highest and lowest of such quotations, unless we obtain fewer than four such quotations, in which case the average of all of such quotations.

“Remaining Scheduled Payments” means, with respect to the notes to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related date of redemption therefor; provided, however, that, if that date of redemption is not an interest payment date with respect to the notes, the amount of the next succeeding scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to that date of redemption.

“Treasury Rate” means, with respect to any date of redemption, the rate per annum equal to the semiannual equivalent yield to maturity, computed as of the third Business Day immediately preceding that date of redemption, of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that date of redemption.

Notice of any redemption will be mailed by first-class mail (or otherwise transmitted in accordance with DTC procedures) at least 10 days but not more than 60 days before the date of redemption to each holder of the notes to be redeemed. If less than all of the notes are to be redeemed, the notes to be redeemed shall be selected by the trustee not more than 60 days before the date of redemption by such method as the trustee deems fair and appropriate in accordance with the procedures of the Depository Trust Company (“DTC”). Unless we default in payment of the redemption price, on and after the date of redemption, interest will cease to accrue on the notes or portions thereof called for redemption.

Except as described above, the notes will not be redeemable by us prior to their maturity date and will not be entitled to the benefit of any sinking fund.

We may acquire notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the Indenture or applicable law.

Change of Control

With respect to the notes, if a Change of Control Repurchase Event occurs, unless we have exercised our right to redeem all of the notes as described under “— Optional Redemption” above, each holder will have the right to require us to repurchase all or any part (equal to $2,000 and integral multiples of $1,000 in excess thereof) of such holder’s notes at a purchase price in cash equal to 101% of the principal amount of the notes plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of holders of record on the relevant interest record date to receive interest due on the relevant interest payment date); provided that after giving effect to the purchase, any notes that remain outstanding shall have a denomination of $2,000 or integral multiples of $1,000 in excess thereof.

Within 30 days following any Change of Control Repurchase Event, unless we have exercised our right to redeem all of the notes as described under “— Optional Redemption” above, we will mail a notice (the “Change of Control Offer”) by first-class mail (or otherwise transmit in accordance with DTC procedures) to each holder, with a copy to the trustee, stating:

S-17

On the Change of Control Payment Date, we will, to the extent lawful:

The paying agent will promptly mail (or otherwise transmit in accordance with DTC procedures) to each holder of the notes called for redemption so tendered the Change of Control Payment for such notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any, provided that each such new note will be in a principal amount of $2,000 and integral multiples of $1,000 in excess thereof.

If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid to the Person in whose name a note is registered at the close of business on such interest record date, and no additional interest will be payable to holders who tender pursuant to the Change of Control Offer.

Except as described above with respect to a Change of Control Repurchase Event, the Indenture does not contain provisions that permit the holders to require us to repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

With respect to the notes, we will not be required to make the Change of Control Offer upon a Change of Control Repurchase Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by us and repurchases all notes validly tendered and not withdrawn under the Change of Control Offer.

We will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934 in connection with the repurchase of notes pursuant to the Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with provisions of the Indenture, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations described in the Indenture by virtue of the conflict.

Holders of the notes electing to have such notes purchased pursuant to a Change of Control Offer will be required to surrender such notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of

S-18

such note completed, to the paying agent at the address specified in the notice, or transfer their notes to the paying agent by book-entry transfer pursuant to the applicable procedures of the paying agent, prior to the close of business on the third Business Day prior to the Change of Control Payment Date.

Our ability to repurchase the notes pursuant to the Change of Control Offer may be limited by a number of factors. Certain events that may constitute a change of control under our indebtedness or that of our subsidiaries and cause a default under the agreements related to such indebtedness may not constitute a Change of Control Repurchase Event under the Indenture. Future indebtedness of ours and our subsidiaries may also contain prohibitions of certain events that would constitute a Change of Control Repurchase Event or require such indebtedness to be repurchased upon a Change of Control Repurchase Event. Moreover, the exercise by the holders of their right to require us to repurchase the applicable notes could cause a default under such indebtedness, even if a Change of Control Repurchase Event itself does not, due to the financial effect of such repurchase on us. Finally, our ability to pay cash to the holders upon a repurchase may be limited by our then existing financial resources. We cannot assure you that sufficient funds will be available when necessary to make any required repurchases. See “Risk Factors — Risks Relating to the Notes — We may be unable to purchase the notes upon a change of control.”

Even if sufficient funds were otherwise available, the terms of our or our subsidiaries’ future indebtedness may prohibit our prepayment of the notes before their scheduled maturity. Consequently, if we or our subsidiaries are not able to prepay our respective senior indebtedness and any such other indebtedness containing similar restrictions or obtain requisite consents, we will not be able to fulfill our repurchase obligations if holders of notes exercise their repurchase rights following a Change of Control Repurchase Event, resulting in a default under the Indenture. A default under the Indenture will result in a cross-default under our or our subsidiaries’ other senior indebtedness.

The Change of Control Repurchase Event provisions described above may deter certain mergers, tender offers and other takeover attempts involving us by increasing the capital required to effectuate such transactions. The definition of “Change of Control” below includes a disposition of all or substantially all of our property and assets and our subsidiaries taken as a whole to any Person. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve a disposition of “all or substantially all” of the property or assets of a Person. As a result, it may be unclear as to whether or not a Change of Control, and thus a Change of Control Repurchase Event, has occurred and whether or not a holder of notes may require us to make an offer to repurchase the notes as described above. The provisions under the Indenture relative to our obligation to make an offer to repurchase the notes as a result of a Change of Control Repurchase Event may be waived or modified with the written consent of the holders of a majority in principal amount of the outstanding notes.

For purposes of this “Change of Control” section, the following terms have the following meanings:

“Change of Control” means:

S-19

Notwithstanding the foregoing, a transaction will not be considered to be a Change of Control if (a) we become a direct or indirect wholly-owned subsidiary of a holding company and (b) immediately following that transaction, (1) the direct or indirect holders of the Voting Stock of the holding company are substantially the same as the holders of our Voting Stock immediately prior to that transaction or (2) no Person or group is the beneficial owner, directly or indirectly, of more than a majority of the Voting Stock of the holding company.

“Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Rating Decline.

“Fitch” means Fitch Inc., a subsidiary of Fimalac, S.A., and its successors.

“Investment Grade” means BBB- or higher by S&P and Baa3 or higher by Moody’s, BBB- or higher by Fitch and BBB- or the equivalent of such ratings by S&P, Fitch or Moody’s, if S&P, Fitch or Moody’s shall not make a rating on the notes publicly available, another Rating Agency.

“Moody’s” means Moody’s Investors Service, Inc., a subsidiary of Moody’s Corporation, and its successors.

“Rating Agency” means each of S&P, Fitch and Moody’s or, to the extent S&P, Fitch or Moody’s do not make a rating on the notes publicly available, a “nationally recognized statistical rating organization” (as such term is defined in Section 3(a)(62) of the Exchange Act) or “organizations”, as the case may be, selected by us (as certified by a resolution of our board of directors), which shall be substituted for S&P, Fitch or Moody’s, as the case may be.

“Rating Decline” means the notes are rated below Investment Grade by all of the Rating Agencies on any date during the period from the date 60 days prior to the first public notice of an arrangement that could result in a Change of Control until the end of the 60 day period following the consummation of such Change of Control (which period will be extended following the consummation of such Change of Control for so long as any Rating Agency has publicly announced that it is considering a possible downgrade in its rating of the notes).

“S&P” means S&P Global Ratings, a division of S&P Global Inc., and its successors.

“Voting Stock” of any specified Person as of any date means the capital stock of such Person that is at the time entitled to vote generally in the election of the board of directors of such Person. With respect to Verisk, references in the foregoing to “Voting Stock” shall refer to our Class A Common Stock, par value $0.001 per share.

Certain Covenants

In addition to the terms set forth under the caption “Description of Debt Securities and Guarantees of Debt Securities” in the accompanying prospectus, the Indenture will contain the following covenants in respect of the notes offered hereby.

S-20

Limitations on Liens

We will not, and will not permit any of our subsidiaries to, create, assume, incur or permit to exist any Lien on any of its or such subsidiaries’ property or assets, whether owned on the date of issuance of the notes or thereafter acquired, or upon any income or profits therefrom, in order to secure any of its indebtedness or that of its subsidiaries, unless the notes are at least equally and ratably secured with such secured indebtedness (together with, if we so determine, any other Indebtedness of or guaranty by us or such subsidiary then existing or thereafter created that is not subordinated to the notes) for so long as such other indebtedness is so secured; provided, however, that the above restrictions shall not apply to the following (the “Permitted Liens”):

Notwithstanding the foregoing, we and any of our subsidiaries may create, assume, incur or guarantee indebtedness secured by a Lien without equally and ratably securing the notes; provided that at the time of such creation, assumption, incurrence or guarantee, after giving effect thereto and to the retirement of any indebtedness that is concurrently being retired, the sum of (a) the aggregate amount of all outstanding indebtedness secured by Liens other than Permitted Liens, and (b) the Attributable Debt of all of our and our subsidiaries’ Sale/Leaseback Transactions (as defined below) permitted by the third paragraph under “Limitation on Sale/Leaseback Transactions” below) does not at such time exceed 7.5% of Consolidated Total Assets.

S-21

Limitation on Sale/Leaseback Transactions

We will not, and will not permit any of our subsidiaries to, enter into any “Sale/Leaseback Transaction” (as defined below) with respect to any real or personal property, whether now owned or hereafter acquired by us or any of our subsidiaries, unless:

(a) we or such subsidiary would, at the time of entering into such arrangement, be able to incur indebtedness secured by a Lien on the property involved in the transaction at least equal in amount to the Attributable Debt with respect to such sale/leaseback transaction, without equally and ratably securing the notes under the covenant described in “— Limitation on Liens” above; or

(b) the net proceeds of the sale of the property to be leased are at least equal to such property’s fair market value, as determined by our board of directors, and the proceeds are applied within 270 days of the effective date of the sale/leaseback transaction to the purchase, construction, development or acquisition of assets or to the repayment of any of our indebtedness that ranks equally with the notes or any indebtedness of our subsidiaries.

This restriction does not apply to sale/leaseback transactions:

A “Sale/Leaseback Transaction” means an arrangement relating to property now owned or hereafter acquired whereby either we transfer, or any of our subsidiaries transfers, such property to a Person and either we or any of our subsidiaries leases it back from such Person.

Notwithstanding the restrictions outlined in the preceding paragraphs, we and our subsidiaries will be permitted to enter into Sale/Leaseback Transactions that would otherwise be subject to such restrictions, without complying with the requirements of clauses (a) and (b) above, if, after giving effect thereto, the aggregate amount of all Attributable Debt with respect to Sale/Leaseback Transactions existing at such time that could not have been entered into except for the provisions described in this paragraph, together with the aggregate amount of all outstanding indebtedness secured by Liens permitted under the last paragraph under “— Limitation on Liens” above, does not exceed 7.5% of Consolidated Total Assets.

Defaults

In addition to the Events of Default listed under the caption “Description of Debt Securities and Guarantees of Debt Securities — Events of Default” in the accompanying prospectus, the following will constitute an “Event of Default” under the Indenture in respect of the notes offered hereby:

(a) a failure to make any payment at maturity, including any applicable grace period, on any of our or a guarantor’s indebtedness in an amount in excess of $50 million and continuance of this failure to pay or (b) a default on any of our or any guarantor’s indebtedness, which default results in the acceleration of indebtedness in an amount in excess of $50 million without such indebtedness having been discharged or the acceleration having been cured, waived, rescinded or annulled, for a period of, in the case of clause (a) or (b) above, 30 days or more after written notice thereof to us by the trustee or to us and the trustee by the holders of at least 25% in aggregate principal amount of the outstanding senior debt securities of such series; provided, however, that if the failure, default or acceleration referred to in clause (a) or (b) above shall cease or be cured, waived, rescinded or annulled, then the event of default shall be deemed cured.

S-24

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following are the material U.S. federal income tax consequences of owning and disposing of notes that are purchased in this offering at the “issue price,” which is the first price at which a substantial amount of the notes is sold to the public, and are held as capital assets for U.S. federal income tax purposes.

This discussion does not describe all of the tax consequences that may be relevant to you in light of your particular circumstances, including alternative minimum tax consequences and differing tax consequences that may apply if you are, for instance:

If you are a partnership for U.S. federal income tax purposes, the U.S. federal income tax treatment of each of your partners will generally depend on the status of the partner and your activities.

This summary is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations, changes to any of which after the date of this prospectus supplement may affect the U.S. federal income tax consequences described herein, possibly on a retroactive basis. This summary does not discuss any aspect of state, local, or non-U.S. taxation, any federal taxes other than U.S. federal income taxes, or the potential application of the Medicare contribution tax. If you are considering the purchase of notes, you should consult your tax adviser with regard to the application of the U.S. federal tax laws to your particular situation, as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

Tax Consequences to U.S. Holders

This section applies to you if you are a U.S. Holder. You are a U.S. Holder if for U.S. federal income tax purposes you are a beneficial owner of a note that is:

Certain Additional Payments

There are circumstances in which we might be required to make payments on a note that would increase the yield of the note, for instance, as described under “Description of Notes — Change of Control.” We intend to take the position that the possibility of such payments does not result in the notes being treated as “contingent

S-25

payment debt instruments” under the applicable Treasury Regulations. Our position is not binding on the Internal Revenue Service (“IRS”). If the IRS were to take a position contrary to that described above, you could be required to accrue interest income based upon a “comparable yield” (as defined in the Treasury Regulations) determined at the time of issuance of the notes (which is not expected to differ significantly from the actual yield on the notes), with adjustments to such accruals when any contingent payments were made that differ from the projected payments based on the comparable yield. In addition, any income on the sale, exchange, retirement or other taxable disposition of the notes would be treated as ordinary income rather than as capital gain. You should consult your tax adviser regarding the tax consequences if the notes were treated as contingent payment debt instruments. The remainder of this discussion assumes that the notes are not treated as contingent payment debt instruments.

Payments of Interest

Stated interest on a note will be taxable to you as ordinary interest income at the time it accrues or is received, in accordance with your method of accounting for U.S. federal income tax purposes. It is expected, and this discussion assumes, that the notes will be issued without original issue discount for U.S. federal income tax purposes.

Sale or Other Taxable Disposition of the Notes

Upon the sale or other taxable disposition of a note, you will recognize taxable gain or loss equal to the difference between the amount realized on the sale or other taxable disposition and your adjusted tax basis in the note. Your adjusted tax basis in a note will equal the cost of your note. For these purposes, the amount realized does not include any amount attributable to accrued but unpaid interest, which are treated as described under “Payments of Interest” above. Gain or loss realized on the sale or other taxable disposition of a note will generally be capital gain or loss and will be long-term capital gain or loss if at the time of sale or other taxable disposition the note has been held for more than one year. Long-term capital gains recognized by non-corporate U.S. Holders may be subject to reduced tax rates. The deductibility of capital losses is subject to limitations.

Tax Consequences to Non-U.S. Holders

This section applies to you if you are a Non-U.S. Holder. You are a Non-U.S. Holder if for U.S. federal income tax purposes you are a beneficial owner of a note that is:

You are not a Non-U.S. Holder if you are a nonresident alien individual present in the United States for 183 days or more in the taxable year of disposition of a note, or if you are a former citizen or former resident of the United States, in either of which cases you should consult your tax adviser regarding the U.S. federal income tax consequences of owning and disposing of a note.

Payments on the Notes

Subject to the discussion below under “FATCA Legislation,” payments of principal and interest on the notes will not be subject to U.S. federal income or withholding tax, provided that, in the case of interest:

S-26

If you cannot satisfy one of the first three requirements described above and interest on the notes is not exempt from withholding because it is effectively connected with your conduct of a trade or business in the United States (as described below), payments of interest on the notes will generally be subject to withholding tax at a rate of 30%, or a lower rate specified by an applicable treaty.

Sale or Other Taxable Disposition of the Notes

Subject to the discussion below under “FATCA Legislation,” you generally will not be subject to U.S. federal income or withholding tax on gain realized on a sale, redemption or other taxable disposition of notes, unless the gain is effectively connected with your conduct of a trade or business in the United States, as described below, except that any amounts attributable to accrued but unpaid interest will be treated as described above under “Payments on the Notes.”

Effectively Connected Income

If interest or gain on a note is effectively connected with your conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base maintained by you), you will generally be taxed in the same manner as a U.S. Holder (see “Tax Consequences to U.S. Holders” above). In this case, you will be exempt from the withholding tax on interest discussed above, although you will be required to provide a properly executed IRS Form W-8ECI in order to claim an exemption from withholding. You should consult your tax adviser with respect to other U.S. tax consequences of the ownership and disposition of notes, including the possible imposition of a branch profits tax at a rate of 30% (or a lower treaty rate) if you are a corporation.

Backup Withholding and Information Reporting

If you are a U.S. Holder, information returns are required to be filed with the IRS in connection with payments on the notes and proceeds received from a sale or other disposition of the notes unless you are an exempt recipient. You may also be subject to backup withholding on these payments in respect of your notes unless you provide your taxpayer identification number and otherwise comply with applicable requirements of the backup withholding rules or you provide proof of an applicable exemption.

If you are Non-U.S. Holder, information returns are required to be filed with the IRS in connection with payments of interest on your notes. Unless you comply with certification procedures to establish that you are not a United States person, information returns may also be filed with the IRS in connection with the proceeds from a sale or other disposition of a note. You may be subject to backup withholding on payments on your notes or on the proceeds from a sale or other disposition of your notes unless you comply with certification procedures to establish that you are not a United States person or otherwise establish an exemption. The certification procedures required to claim the exemption from withholding tax on interest described above will avoid backup withholding as well.

Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against your U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

S-27

FATCA Legislation

Provisions commonly referred to as “FATCA” impose withholding of 30% on payments of interest on the notes, as well as of gross proceeds of dispositions of the notes, to “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied, or an exemption applies, which is typically evidenced by delivery of a properly executed IRS Form W-8BEN-E. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. In addition, regulations proposed by the U.S. Treasury Department (the preamble to which indicates that taxpayers may rely on the regulations pending their finalization) would eliminate the requirement under FATCA of withholding on gross proceeds (other than payments of interest) of the disposition of the notes. If FATCA withholding is imposed, a beneficial owner that is not a foreign financial institution generally will be entitled to a refund of any amounts withheld by filing a U.S. federal income tax return (which may entail significant administrative burden). You should consult your tax adviser regarding the effects of FATCA on your investment in the notes.

S-28

UNDERWRITING (CONFLICTS OF INTEREST)

HSBC Securities (USA) Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated are acting as representatives of each of the underwriters named below. Subject to the terms and conditions set forth in a firm commitment underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the aggregate principal amount of the notes set forth opposite its name below.

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the notes sold under the underwriting agreement if any of these notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the underwriters and their controlling persons against certain liabilities in connection with this offering, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commissions and Discounts

The representatives have advised us that the underwriters propose initially to offer the notes to the public at the applicable public offering price set forth on the cover page of this prospectus supplement and to certain dealers at such price less a concession not in excess of 0.40% of the principal amount of the notes. The underwriters may allow, and the dealers may re-allow, a discount not in excess of 0.25% of the principal amount of the notes to other dealers. After the initial offering, the public offering price, concession, reallowance discount or any other term of the notes may be changed.

The expenses of the offering, not including the underwriting discount, are estimated at $1.30 million and are payable by us.

S-29

The following table shows the underwriting discount that we will pay to the underwriters in connection with the offering of the notes:

New Issue of Notes

The notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any national securities exchange or for inclusion of the notes on any automated dealer quotation system. We have been advised by the underwriters that they presently intend to make a market in the notes after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public trading market for the notes does not develop, the market price and liquidity of such notes may be adversely affected. If the notes are traded, it may trade at a discount from its initial offering price, depending on prevailing interest rates, the market for similar securities, our operating performance and financial condition, general economic conditions and other factors.

No Sales of Similar Securities

We have agreed that we will not, through and including the business day following the closing of this offering, without first obtaining the prior written consent of the representatives, directly or indirectly, issue, offer, sell, offer to sell or grant any option to sell, pledge, transfer or otherwise dispose of any debt securities or securities exchangeable for or convertible into debt securities, except for the notes sold to the underwriters pursuant to the underwriting agreement.

Short Positions

In connection with the offering, the underwriters may purchase and sell the notes in the open market. These transactions may include short sales and purchases on the open market to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater principal amount of the notes than they are required to purchase in the offering. The underwriters must close out any short position by purchasing the notes in the open market. A short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the notes in the open market after pricing that could adversely affect investors who purchase in the offering.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of the notes or preventing or retarding a decline in the market price of the notes. As a result, the price of the notes may be higher than the price that might otherwise exist in the open market.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the notes. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Relationships

The underwriters and certain of their affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities.

S-30

The underwriters and certain of their affiliates have, from time to time, performed, and may in the future perform, various commercial and investment banking and financial advisory services for us and our subsidiaries for which they received or may in the future receive customary fees and expenses. In particular, affiliates of certain underwriters are lenders under our revolving credit facility, and to the extent such debt is repaid with the proceeds of this offering, such affiliates would receive a portion of this offering. In addition, an affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated acts as administrative agent, swing line lender and L/C issuer under the facility, Merrill Lynch, Pierce, Fenner & Smith Incorporated acts as the sole lead arranger and sole bookrunner under the facility and affiliates of certain underwriters act as co-syndication agents under the facility.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, those underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Conflicts of Interest

Certain affiliates of the underwriters will receive at least 5% of the net proceeds of this offering in connection with the repayment of amounts outstanding under our revolving credit facility. See “Use of Proceeds.” Accordingly, this offering is being made in compliance with the requirements of FINRA Rule 5121. In accordance with that rule, no “qualified independent underwriter” is required because the securities will be rated investment grade. Such underwriters will not confirm sales to discretionary accounts without the prior written approval of the customer.

Settlement

We expect that delivery of the notes will be made to investors on or about March 6, 2019, which will be the fifth New York business day following the date of this prospectus supplement (such settlement being referred to as “T+5”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes prior to the delivery of the notes hereunder may be required, by virtue of the fact that the notes initially settle in T+5, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes prior to their date of delivery hereunder should consult their advisors.

Offering Restrictions

Canada

The notes may be sold only to purchasers purchasing, or deemed to be purchasing, as principals that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

S-31

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement and the accompanying prospectus (including any amendment thereto) contain a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

PRIIPs Regulation / Prospectus Directive / Prohibition of sales to EEA retail investors

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”).

Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared, and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. This prospectus supplement has been prepared on the basis that any offer of notes in any Member State of the EEA will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of notes.
