Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On March 16, 2020, Martin Marietta Materials, Inc. (“Martin Marietta”) issued $500 million aggregate principal amount of 2.500% Senior Notes due 2030 (the “Senior Notes”) pursuant to a base indenture, dated as of May 22, 2017 (the “Base Indenture”), as amended and supplemented from time to time, including by the Third Supplemental Indenture, dated as of March 16, 2020 (the “Third Supplemental Indenture” and, together with the Base Indenture, the “Indenture”) between Martin Marietta and Regions Bank, as trustee (the “Trustee”), governing the Senior Notes.

The Senior Notes will mature on March 15, 2030 and will have an interest rate of 2.500%. Interest will be paid semiannually on the 15th day of March and September, commencing September 15, 2020.

The Senior Notes are Martin Marietta’s senior unsecured obligations and rank equally in right of payment with all of its existing and future senior indebtedness and will rank senior in right of payment to all of its future subordinated indebtedness. The Senior Notes are effectively subordinated to all of its existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness. The Senior Notes are not guaranteed by any of Martin Marietta’s subsidiaries and are structurally subordinated to all of the existing and future indebtedness and other liabilities (including trade accounts payable) and preferred equity of Martin Marietta’s subsidiaries.

The net proceeds of the offering are expected to be used for general corporate purposes, which will include, among other uses, repayment at maturity of approximately $300 million aggregate principal amount of Martin Marietta’s existing floating rate notes due 2020.

Optional Redemption. Prior to December 15, 2029 (the “Par Call Date”), Martin Marietta may redeem the Senior Notes, at its option, at any time in whole or from time to time in part at a price equal to the greater of: (i) 100% of the principal amount of the Senior Notes to be redeemed and (ii) the sum of the present values of the principal amount of the Senior Notes to be redeemed and the remaining scheduled payments of interest thereon after the date of optional redemption (an “Optional Redemption Date”) through the Par Call Date (assuming, for this purpose, that the Senior Notes are scheduled to mature on the Par Call Date), excluding interest, if any, accrued thereon to such Optional Redemption Date, discounted to such Optional Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined in the Indenture) plus 30 basis points (or 0.300%) plus unpaid interest, if any, accrued thereon to, but excluding, such Optional Redemption Date. On or after the Par Call Date and prior to maturity, Martin Marietta may redeem the Senior Notes, at its option, at any time in whole or from time to time in part at a price equal to 100% of the principal amount of the Senior Notes to be redeemed, plus unpaid interest, if any, accrued thereon to, but excluding, the Optional Redemption Date.

Change of Control Repurchase Event. If a Change of Control Repurchase Event (as defined in the Indenture) occurs, unless Martin Marietta has exercised its right to redeem the Senior Notes in full, Martin Marietta will be required to offer to repurchase all of the outstanding Notes at a repurchase price equal to 101% of their principal amount, plus unpaid interest, if any, accrued thereon to, but excluding, the date of repurchase.

Other Covenants. The Indenture contains covenants that restrict Martin Marietta’s ability, with certain exceptions, to (i) incur debt secured by liens, (ii) engage in sale and leaseback transactions and (iii) merge or consolidate with or into, or transfer all or substantially all of the assets of Martin Marietta and its subsidiaries, taken as a whole, to, another entity. These covenants are subject to a number of important exceptions and qualifications, as described in the Indenture.

Events of Default. The Indenture provides for customary events of default (subject in certain cases to customary grace and cure periods), which include non-payment, breach of covenants in the Indenture and certain events of bankruptcy and insolvency. Generally, if an event of default occurs, the Trustee or holders of at least 25% in aggregate principal amount of the then outstanding Senior Notes may declare the principal of all such outstanding Senior Notes and any accrued interest thereon immediately due and payable.

The Senior Notes have been registered under the Securities Act of 1933, as amended (the “Act”), pursuant to an effective shelf registration statement on Form S-3ASR (File No. 333-217991), as supplemented by the prospectus supplement dated March 5, 2020, filed with the Securities and Exchange Commission under the Act.

The foregoing description of the Indenture (including the form of Senior Notes) does not purport to be complete and is qualified in its entirety by reference to the full text of the Base Indenture and the Third Supplemental Indenture (including the form of Senior Notes), which are attached hereto as Exhibits 4.1, 4.2 and 4.3 and incorporated by reference herein.

Item 8.01. Other Events.

In connection with the Senior Notes offering, copies of the legal opinions of Robinson, Bradshaw & Hinson, P.A. and Cravath, Swaine & Moore LLP relating to the Senior Notes are attached hereto as Exhibits 5.1 and 5.2, respectively.

WHEREAS, this Supplemental Indenture is being entered into pursuant to the provisions of Section 2.3 and Section 9.1(6) of the Indenture;

WHEREAS, the Corporation has requested that the Trustee execute and deliver this Supplemental Indenture; and

WHEREAS, all things necessary to make this Supplemental Indenture a valid agreement of the Corporation, in accordance with its terms, and to make the Notes, when executed by the Corporation and authenticated and delivered by the Trustee, the valid obligations of the Corporation, have been performed, and the execution and delivery of this Supplemental Indenture has been duly authorized in all respects.

NOW THEREFORE, in consideration of the premises and the purchase and acceptance of the Notes by the Holders thereof, and for the purpose of setting forth, as provided in the Indenture, the forms and terms of the Notes and to make other modifications to the Indenture pertaining to the Notes, the Corporation and the Trustee hereby enter into this Supplemental Indenture, which modifies the Indenture with respect to (and only with respect to) the Notes, as follows:

SECTION 1.2 Additional Definitions. Solely for the purposes of this Supplemental Indenture in connection with the Notes, the following terms shall have the following meanings:

“Attributable Debt” for a lease means the carrying value of the capitalized rental obligation determined under U.S. generally accepted accounting principles, whether or not such obligation is required to be shown on the balance sheet as a long‑term liability. The carrying value may be reduced by the capitalized value of the rental obligations, calculated on the same basis, that any sublessee has for all or part of the same property.

“Below Investment Grade Rating Event” means the rating on the Notes is lowered by at least two of the three Rating Agencies and the Notes are rated below an Investment Grade Rating by at least two of the three Rating Agencies on any day during the period (which period shall be extended so long as the rating of the Notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) commencing 60 days prior to the first public notice of the earlier of the Corporation’s intention to effect a Change of Control and the occurrence of a Change of Control and ending 60 days following consummation of such Change of Control.

(2) any sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all or substantially all of the assets of the Corporation and its Subsidiaries, taken as a whole, to any Person or group of related Persons for the purpose of Section 13(d)(3) of the Exchange Act, together with any affiliates thereof, other than any such sale, lease, exchange or other transfer to one or more of the Corporation’s Subsidiaries (whether or not otherwise in compliance with the provisions of this Indenture); or

(3) the adoption of a plan relating to the liquidation, dissolution or winding up of the Corporation.

Notwithstanding the foregoing, a transaction effected to create a holding company for the Corporation shall not be deemed to involve a Change of Control if (a) pursuant to such transaction the Corporation becomes a wholly owned subsidiary of such holding company and (b) the holders of the outstanding Voting Stock of such holding company immediately following such transaction are the same as the holders of the Corporation’s outstanding Voting Stock immediately prior to such transaction.

“Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the Assumed Remaining Life that would be utilized, 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 Assumed Remaining Life.

(2) goodwill, patents and trademarks,

all as stated on the Corporation’s most recent publicly available consolidated balance sheet preceding such date of determination.

“Fitch” means Fitch Inc. and its successors.

“Initial Notes” means $500.0 million aggregate principal amount of the Corporation’s 2.500% Senior Notes due 2030 issued under this Supplemental Indenture and the Indenture on the date hereof substantially in the form set forth in Exhibit A hereto.

“Long‑Term Debt” means Debt that by its terms matures on a date more than 12 months after the date it was created or Debt that the obligor may extend or renew without the obligee’s consent to a date more than 12 months after the Debt was created.

(1) any such facility or property which is financed by obligations of any State, political subdivision of any State or the District of Columbia under terms which permit the interest payable to the holders of the obligations to be excluded from gross income as a result of the plant, facility or property satisfying the conditions of Section 103(b)(4)(C), (D), (E), (F) or (H) or Section 103(b)(6) of the Internal Revenue Code of 1954 or Section 142(a) or Section 144(a) of the Internal Revenue Code of 1986, or of any successors to such provisions; or

(2) any such facility or property which, in the opinion of the Board of Directors of the Corporation, is not of material importance to the total business conducted by the Corporation and its Subsidiaries taken as a whole.

Notwithstanding the foregoing, the chief executive officer or chief financial officer of the Corporation may at any time declare any mining and quarrying or manufacturing facility or other property to be a Principal Property by delivering a certificate to that effect to the Trustee.

ARTICLE III

Additional Covenants

SECTION 3.1 Limitations on Liens. Subject to the following two sentences, the Corporation shall not, and shall not permit any Restricted Subsidiary to, as security for any Debt, incur a Lien on any Restricted Property, unless the Corporation or such Restricted Subsidiary secures or causes to be secured any outstanding Notes equally and ratably with all Debt secured by such Lien (it being understood that such Lien may equally and ratably secure such Notes and any other obligations of the Corporation or its Subsidiaries that are not subordinated in right of payment to any outstanding Notes). The foregoing restrictions will not apply to, among other things, Liens:

(i) existing on the Issue Date of the Notes or existing at the time an entity becomes a Restricted Subsidiary;

(ii) existing at the time of the acquisition of the Restricted Property or incurred to finance all or some of the purchase price or cost of construction; provided that the Lien may not extend to any other Restricted Property (other than, in the case of construction, unimproved real property) owned by the Corporation or any of its Restricted Subsidiaries at the time the property is acquired or the Lien is incurred; and provided, further, that the Lien may not be incurred more than one year after the later of the acquisition, completion of construction or commencement of full operation of the property;

(iii) securing Debt of the Corporation owed to a Restricted Subsidiary or securing Debt of a Restricted Subsidiary owed to the Corporation or another Restricted Subsidiary;

(iv) existing at the time an entity merges into, consolidates with, or enters into a share exchange with the Corporation or a Restricted Subsidiary or a Person transfers or leases all or substantially all its assets to the Corporation or a Restricted Subsidiary;

(v) in favor of a government or governmental entity that secures payment pursuant to a contract, subcontract, statute or regulation, secures Debt guaranteed by the government or governmental agency, secures Debt incurred to finance all or some of the purchase price or cost of construction of goods, products or facilities produced under contract or subcontract for the government or governmental entity, or secures Debt incurred to finance all or some of the purchase price or cost of construction of the property subject to the Lien; or

(vi) extending, renewing or replacing in whole or in part a Lien (an “existing Lien”) permitted by any of clauses (i) through (v); provided that such Lien may not extend beyond the property subject to the existing Lien and the Debt secured by the Lien may not exceed the amount of Debt secured at the time by the existing Lien unless the existing Lien or a predecessor Lien equally and ratably secures the outstanding Notes and the Debt.

In addition and notwithstanding the foregoing restrictions, the Corporation and any of its Restricted Subsidiaries may, without securing the Notes, incur a Lien that otherwise would be subject to the foregoing restrictions; provided that after giving effect to such Lien the aggregate amount of all Debt secured by Liens that otherwise would be prohibited by this Section 3.1 (for the avoidance of doubt, excluding Debt secured by a Lien permitted by any of clauses (i) through (vi) above), plus all Attributable Debt in respect of Sale‑Leaseback Transactions that otherwise would be prohibited by Section 3.2 at the time such Lien is incurred would not exceed 15% of Consolidated Net Tangible Assets.

If, upon any consolidation, merger or transfer described in Section 5.1 of the Indenture, a Restricted Property would become subject to an attaching Lien that secures Debt, then, before the consolidation, merger or transfer occurs, the Corporation by supplemental indenture shall secure the Securities by a direct lien on such Restricted Property. The direct Lien shall have priority over all Liens on such Restricted Property except those already encumbering such Restricted Property. The direct Lien may equally and ratably secure the Securities and any other obligation of the Corporation or a Subsidiary. Notwithstanding the foregoing, the Corporation need not comply with the above provisions of this paragraph if (i) upon the consolidation, merger or transfer, the attaching Lien will secure the Securities equally and ratably with or prior to Debt secured by the attaching Lien or (ii) pursuant to the other provisions of this Section 3.1, the Corporation or a Restricted Subsidiary would not be prohibited from creating a Lien on the Restricted Property to secure Debt at least equal in amount to that secured by the attaching Lien.

This Section 3.1 is one of the covenants eligible for the provisions of Section 8.3 of the Indenture.

SECTION 3.2 Limitations on Sale and Lease‑Back Transactions. Subject to the following sentence, the Corporation shall not, and shall not permit any Restricted Subsidiary to, enter into a Sale‑Leaseback Transaction, unless:

(i) the lease is between the Corporation and a Restricted Subsidiary or between Restricted Subsidiaries;

(ii) the Corporation or such Restricted Subsidiary would be entitled, pursuant to Section 3.1, to create a Lien on the property to be leased securing Debt in an amount at least equal in amount to the Attributable Debt in respect of the Sale‑Leaseback Transaction without equally and ratably securing the outstanding Notes under Section 3.1;

(iii) the Corporation owns or acquires other property which will be made a Principal Property and is determined by the Board of Directors of the Corporation to have a fair value equal to or greater than the Attributable Debt incurred;

(iv) within 270 days of the effective date of the lease, the Corporation makes Capital Expenditures with respect to a Principal Property in an amount at least equal to the amount of the Attributable Debt incurred; or

(v) the Corporation or a Restricted Subsidiary makes an optional prepayment in cash of its Debt or finance lease obligations at least equal in amount to the Attributable Debt for the lease, the prepayment is made within 270 days of the effective date of the lease, the Debt prepaid is not owned by the Corporation or a Restricted Subsidiary, the Debt prepaid is not subordinated in right of payment to any of the Notes, and the Debt prepaid was Long‑Term Debt at the time it was created.

In addition and notwithstanding the foregoing restrictions, the Corporation and any of its Restricted Subsidiaries may, without securing the Notes, enter into a Sale‑Leaseback Transaction that otherwise would be subject to the foregoing restrictions; provided that after giving effect to such Sale‑Leaseback Transaction the aggregate amount of all Debt secured by Liens that otherwise would be prohibited by Section 3.1 (for the avoidance of doubt, excluding Debt secured by a Lien permitted by any of clauses (i) through (vi) thereof), plus all Attributable Debt in respect of Sale‑Leaseback Transactions that otherwise would be prohibited by this Section 3.2 would not exceed 15% of Consolidated Net Tangible Assets.

This Section 3.2 is one of the covenants eligible for the provisions of Section 8.3 of the Indenture.

SECTION 3.3 Change of Control Repurchase Event. If a Change of Control Repurchase Event occurs (unless the Corporation has exercised its right to redeem the Notes in full in accordance with Section 2.8 hereof), the Corporation shall make an irrevocable offer (subject to consummation of the Change of Control Repurchase Event) (a “Change of Control Offer”) to each Holder of Notes (except any such Notes in respect of which the Corporation has exercised its right of redemption in full in accordance with Section 2.8 hereof) to repurchase all or, at the election of such Holder, any part (equal to a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Notes for cash at a price equal to 101% of the principal amount of such Notes to be repurchased plus unpaid interest, if any, accrued thereon to, but excluding, the repurchase date. Notwithstanding the foregoing, the Corporation shall pay any interest installment due on an Interest Payment Date which occurs on or prior to the repurchase date to the Holders of the Notes as of the close of business on the record date immediately preceding such Interest Payment Date.

(a) The Corporation shall send a notice to each Holder of the Notes by first class mail, with a copy to the Trustee, within 30 days following the date upon which any Change of Control Repurchase Event has occurred, or at its option, prior to any Change of Control but after the public announcement of the pending Change of Control. The notice shall govern the terms of the Change of Control Offer and shall describe the transaction that constitutes or may constitute the Change of Control Repurchase Event and shall irrevocably offer (subject to consummation of the Change of Control Repurchase Event) to repurchase all of such Notes on the repurchase date specified in the notice. Subject to the following sentence, the repurchase date shall be at least 30 days but no more than 60 days from the date such notice is sent (a “Change of Control Payment Date”). If the notice is sent prior to the date of consummation of the Change of Control, the notice shall state that the Change of Control Offer is conditioned on the Change of Control Repurchase Event occurring on or prior to the repurchase date specified in the notice. Holders electing to have their Notes purchased pursuant to a Change of Control Offer shall be required to surrender their Notes, with the form entitled “Option of Holder to Elect Repurchase” on the reverse 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. The Paying Agent shall promptly send to each Holder of Notes properly tendered the repurchase price for such Notes, and the Trustee, upon the Corporation’s execution and delivery of the related Notes, shall promptly authenticate and send (or cause to be transferred by book‑entry) to each Holder a new Note equal in principal amount to any unrepurchased portion of any Notes properly tendered.

(b) On the Change of Control Payment Date, the Corporation shall, to the extent lawful: (i) accept for payment all properly tendered Notes or portions of Notes that have not been validly withdrawn; (ii) on or before 10:00 a.m. (New York City time) on such date, deposit with the Trustee or with the Paying Agent (other than the Corporation or an Affiliate of the Corporation) money sufficient to pay the required payment for all properly tendered Notes or portions of Notes that have not been validly withdrawn; and (iii) deliver or cause to be delivered to the Trustee the repurchased Notes, accompanied by an Officers’ Certificate stating the aggregate principal amount of repurchased Notes. The Trustee or the Paying Agent shall promptly return to the Corporation any money deposited with the Trustee or the Paying Agent by the Corporation in excess of the amounts necessary to pay the repurchase price of all Notes to be repurchased.

(c) The Corporation shall comply with the requirements of Rule 14e‑1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture or the Notes, the Corporation shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 3.3 or the Notes by virtue of any such conflict.

(d) The Corporation shall not be required to make an offer to repurchase the Notes upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements of this Section 3.3 and such third party purchases all Notes properly tendered and not withdrawn by the Holders thereof under its offer.

(e) If Notes tendered in a Change of Control Offer are paid or if the Corporation has deposited with the Trustee or the Paying Agent money sufficient to pay the repurchase price of all Notes to be repurchased, on and after the repurchase date, interest shall cease to accrue on the Notes or the portions of Notes tendered and not withdrawn in a Change of Control Offer (regardless of whether certificates for such Notes are actually surrendered). If any Security tendered in a Change of Control Offer shall not be so paid upon surrender for repurchase because of the failure of the Corporation to comply with paragraph (c) of this Section 3.3, interest shall be paid on the unpaid principal from the repurchase date until such principal is paid, and, to the extent lawful, on any interest not paid on such unpaid principal, in each case, at the rate provided in such Security.

This Section 3.3 is one of the covenants eligible for the provisions of Section 8.3 of the Indenture.

SECTION 3.4 Maintenance of Office or Agency. In the event that certificated Notes are outstanding, then, for so long as such certificated Notes are outstanding, the Corporation shall maintain in the United States, an office or agency where certificated Notes may be presented or surrendered for payment and where certificated Notes may be surrendered for registration of transfer or exchange. The Corporation shall give prompt written notice to the Trustee of the location, and any change in the location, of each such office or agency. If at any time the Corporation shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations may be made or served at the corporate trust office of the Trustee, and the Corporation hereby appoints the Trustee as its agent to receive all such presentations.

Martin Marietta Materials, Inc.

$500,000,000 Aggregate Principal Amount of 2.500% Senior Notes due 2030

Ladies and Gentlemen:

We have acted as counsel for Martin Marietta Materials, Inc., a North Carolina corporation (the “Company”), in connection with the public offering and sale by the Company of $500,000,000 aggregate principal amount of its 2.500% Senior Notes due 2030 (the “Notes”) to be issued pursuant to an Indenture dated as of May 22, 2017 (the “Base Indenture”), between the Company and Regions Bank (the “Trustee”), as amended and supplemented by the Third Supplemental Indenture dated as of March 16, 2020 (together with the Base Indenture, the “Indenture”), between the Company and the Trustee.

In that connection, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments as we have deemed necessary or appropriate for the purposes of this opinion, including the Indenture and the Registration Statement on Form S‑3 (Registration No. 333‑217991) filed with the Securities and Exchange Commission (the “Commission”) on May 12, 2017, for registration under the Securities Act of 1933, as amended (the “Securities Act”), of various securities of the Company, to be issued from time to time by the Company, as amended by Amendment No. 1 thereto filed with the Commission on June 5, 2017 (such Registration Statement, as amended by such amendment, being hereinafter referred to as the “Registration Statement”). As to various questions of fact material to this opinion, we have relied upon representations of officers or directors of the Company and documents furnished to us by the Company without independent verification of their accuracy. We have also assumed (a) the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of all documents submitted to us as duplicates or copies, (b) that the Indenture has been duly authorized, executed and delivered by, and represents a legal, valid and binding obligation of, the Trustee, (c) that the Indenture has been duly authorized, executed and delivered by the Company and (d) that the Notes have been duly authorized, executed and delivered by the Company.

Based on the foregoing and subject to the qualifications set forth herein, we are of opinion that when the Notes are authenticated in accordance with the provisions of the Indenture and delivered and paid for, the Notes will constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms and entitled to the benefits of the Indenture (subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other laws affecting creditors’ rights generally from time to time in effect and to general principles of equity, including concepts of materiality, reasonableness, good faith and fair dealing, regardless of whether such enforceability is considered in a proceeding in equity or at law).

We hereby consent to the filing of this opinion with the Commission as an exhibit to the Registration Statement. We also consent to the reference to our firm under the caption “Legal Matters” in the Registration Statement. In giving this consent, we do not thereby admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission.

We are admitted to practice in the State of New York, and we express no opinion as to matters governed by any laws other than the laws of the State of New York and the Federal laws of the United States of America. In particular, we do not purport to pass on any matter governed by the laws of the State of North Carolina.
