Martin Marietta issues $5.5 billion in senior notes to fund Lhoist North America deal
Martin Marietta issued $5.5 billion of senior unsecured notes in five series maturing 2029 through 2056, with the proceeds, along with a $1.5 billion term loan, earmarked for the cash purchase of Lhoist North America. The notes carry a special mandatory redemption at 101% of principal if the acquisition is not completed or is abandoned, which adds a repayment risk for shareholders if the deal falls through.
Key points
- Five series totaling $5.5 billion: $750 million due 2029, $1.25 billion due 2032, $1 billion due 2034, $1.5 billion due 2036 and $1 billion due 2056
- Coupons range from 4.850% (2029 notes) to 6.375% (2056 notes)
- Proceeds plus a $1.5 billion senior unsecured term loan will pay the cash consideration for the Lhoist North America acquisition
- Closing of the offering is expected in the third quarter of 2026, subject to customary conditions
