Martin Marietta Materials, Inc. is offering $300,000,000 aggregate principal amount of its Floating Rate Senior Notes due 2019 (the “floating rate notes”), $500,000,000 aggregate principal amount of its 3.500% Senior Notes due 2027 (the “2027 fixed rate notes”) and $600,000,000 aggregate principal amount of its 4.250% Senior Notes due 2047 (the “2047 fixed rate notes” and, together with the 2027 fixed rate notes, the “fixed rate notes”). We collectively refer to the floating rate notes and the fixed rate notes as the “notes.” The floating rate notes will accrue interest from, and including, December 20, 2017 at a per annum rate equal to three-month LIBOR for U.S. dollars plus 0.500% (or 50 basis points), reset quarterly as more fully described herein, and will be payable in arrears on March 20, June 20, September 20 and December 20 of each year, beginning on March 20, 2018. The 2027 fixed rate notes will accrue interest from, and including, December 20, 2017 at a per annum rate of 3.500%, and will be payable in arrears on June 15 and December 15 of each year, beginning on June 15, 2018. The 2047 fixed rate notes will accrue interest from, and including, December 20, 2017 at a per annum rate of 4.250%, and will be payable in arrears on June 15 and December 15 of each year, beginning on June 15, 2018. The floating rate notes will mature on December 20, 2019, the 2027 fixed rate notes will mature on December 15, 2027 and the 2047 fixed rate notes will mature on December 15, 2047.
We have the option to redeem some or all of the fixed rate notes prior to their stated maturity date at any time and from time to time, as described under the heading “Description of the notes—Optional redemption.” The floating rate notes will not be subject to optional redemption by us prior to their stated maturity date. If a Change of Control Repurchase Event (as defined herein) occurs, we 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, unless, in the case of the fixed rate notes, we have exercised our right to redeem such notes in full. See “Description of the notes—Change of Control Repurchase Event.”
The closing of this offering is not conditioned upon the consummation of the Acquisition (as defined herein), which, if consummated, will occur subsequent to the closing of this offering. If (i) the Acquisition is not consummated prior to September 30, 2018, (ii) the Purchase Agreement (as defined herein) is terminated at any time prior to September 30, 2018 (other than as a result of consummating the Acquisition) or (iii) we publicly announce at any time prior to September 30, 2018 that we will no longer pursue the consummation of the Acquisition, then we will be required to redeem all of the outstanding fixed rate notes pursuant to a special mandatory redemption at a redemption price equal to 101% of the aggregate principal amount of the fixed rate notes, plus accrued and unpaid interest to, but excluding, the Special Mandatory Redemption Date (as defined herein). There is no escrow account for, or security interest in, the proceeds from the sales of the fixed rate notes for the benefit of holders of such fixed rate notes. The floating rate notes will not be subject to the special mandatory redemption. See “Description of the notes—Special mandatory redemption.”
The notes will be our senior unsecured obligations, will rank equally in right of payment with all of our existing and future senior indebtedness and will rank senior in right of payment to all of our future subordinated indebtedness. The notes will be effectively subordinated to all of our existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness. The notes will not be guaranteed by any of our subsidiaries and will be structurally subordinated to all of the existing and future indebtedness and other liabilities (including trade accounts payable) and preferred equity of our subsidiaries.
