Martin Marietta Increases Quarterly Cash Dividend

RALEIGH, N.C., Aug. 23, 2018 (GLOBE NEWSWIRE) -- Martin Marietta Materials, Inc. MLM, today announced that its Board of Directors has approved a nine percent increase in the quarterly cash dividend, raising it from $0.44 per share to $0.48 per share on the Company's outstanding common stock. This dividend, which represents a cash dividend of $1.92 per share on an annualized basis, is payable on September 28, 2018, to shareholders of record at the close of business on September 4, 2018.

Ward Nye, Chairman and Chief Executive Officer stated, "Since becoming a public company in 1994, Martin Marietta has maintained or increased its quarterly cash dividend payment. Today's announced increase builds on our track record of delivering a meaningful and sustainable dividend as part of our long-standing and balanced capital allocation priorities.  Martin Marietta's strong cash flow and financial flexibility allow the Company to simultaneously return capital to shareholders through growing dividends and share repurchases, while also prudently investing in growth opportunities."
