Item 8.01. Other Events.

 

As previously announced, on June 27, 2026, Martin Marietta Materials, Inc., a North Carolina corporation (“Martin Marietta” or the “Company”), and LNA Holding SRL, a société à responsabilité limitée organized under the laws of Belgium, entered into a Securities Sale Agreement, pursuant to which Martin Marietta will acquire all of the outstanding equity interests in Lhoist North America, Inc., which owns and operates the business of producing, distributing, marketing and selling lime, dolomitic lime, limestone- and dolomitic stone-based industrial minerals and products, and aggregates in North America, for $13.5 billion in cash and shares of Martin Marietta common stock (the “Transaction”).

 

On August 5, 2026, Martin Marietta issued a press release announcing that it has received all necessary regulatory approvals with respect to the Transaction. Martin Marietta expects the Transaction to close in the third quarter of 2026, subject to customary closing conditions.

 

A copy of the press release is furnished as Exhibit 99.1 hereto and is incorporated by reference herein.

 

The information in this Item 8.01 of this Current Report on Form 8-K, including Exhibit 99.1 attached hereto, is being furnished to the U.S. Securities and Exchange Commission and shall not be deemed “filed” for purposes of Section 18 of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section. This information shall not be deemed to be incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

 

 

 
 

 

 

Forward-Looking Statements

 

This Current Report on Form 8-K contains forward-looking statements under the federal securities laws, including the Private Securities Litigation Reform Act of 1995. These statements include: the expected timing for completing the transaction. These statements involve risks and uncertainties and are based on assumptions that the Company believes are reasonable, but which may differ materially from actual results, including, among others, risks and uncertainties relating to the timing of consummation of the transaction; the risk that the conditions to closing of the transaction may not be satisfied, or that the closing of the transaction does not occur. These statements reflect the Company’s current expectations or forecasts of future events. You can identify these statements because they do not relate only to historical or current facts and may use words such as “guidance”, “anticipate”, “may”, “expect”, “should”, “believe”, “will”, and other words of similar meaning in connection with future events or future performance. Any or all of the Company’s forward-looking statements herein and in other publications may prove to be incorrect.

 

A further list and description of risks, uncertainties and other matters can be found in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 and in the Company’s subsequent reports on Form 10-Q, including the sections thereof captioned “Other Matters” and “Item 1A. Risk Factors”, and in the Company’s subsequent reports on Form 8-K. Except as required by law, the Company does not undertake any obligation to publicly update any forward-looking statements whether as a result of new information, future events, changed circumstances or otherwise.
