Can Martin Marietta Stock Jump 30%?

For questions about this article or underlying research, email help@trefis.com.

Martin Marietta Materials (MLM) stock trades at 12.4 times earnings, compared with 22.9 for the median S&P 500 company. The shares lost 18.1% over the past year. A 30% rise would still leave them below their February 10, 2026 close of $705.09. Martin Marietta only reaches that level if its low multiple signals a sound business on sale, rather than a fair price for earnings that will not last. So what does a buyer get from Martin Marietta at that low price?

Martin Marietta Grows Faster At 12 Times Earnings

A buyer gets a company growing faster than the median S&P 500 firm while retaining more of each sales dollar as operating profit. Revenue at Martin Marietta rose 14.8% over the four quarters ended June 30, 2026, compared with an 8.4% gain for the median company. The operating margin over those same twelve months was 21.2%, against 18.5%.

A single business generates most of that revenue. Aggregates accounted for $5,004 million of the company’s $6,150 million of revenue in fiscal 2025. On the fiscal Q2 2026 call, management pointed to strong infrastructure and heavy nonresidential demand, alongside over $150 billion in federal infrastructure funds yet to be invested. Based on those figures, the low multiple looks like a discount on a business that is doing well.

Most Of Martin Marietta’s Profit Came From One Quarter

Net income of $2,457 million over the four quarters ended June 30, 2026, underpins that low multiple, and fiscal Q1 2026 alone supplied $1,513 million of it. Operating income over the same twelve months was $1,417 million, falling well short of that net income. The low multiple is therefore computed on a profit figure swollen by a single quarter.

Growth also looks different over a longer stretch. Revenue growth averaged 1.7% across the twelve-month periods ended June 2024, 2025 and 2026, falling far below the most recent period’s rise. Revenue fell 12.0% in the first of those periods. During fiscal Q2 2026, total shipments rose 17% while organic shipments increased 2.3%. Management said the total reflected contributions from the Quikrete operations it now owns and the New Frontier Materials acquisition. That provides a reason the market may be right to pay less: much of Martin Marietta’s growth came from acquisitions.

How Martin Marietta Plans To Lift Earnings

Management expects to generate about $350 million a year in cash flow improvements by the end of 2027 by making better use of its plants, streamlining its network and spending less on upkeep. That is a pretax figure, so it does not compare directly with the $810 million of free cash flow the company produced over the latest twelve months. For fiscal 2026, management raised the midpoint of its revenue guidance to $7.3 billion from the $7.16 billion it guided in April, but held its adjusted EBITDA guide at $2.36 billion to $2.5 billion. It said the earnings added by New Frontier Materials should largely offset higher diesel costs.

Buying at $507.17 is a bet that Martin Marietta fixes a real problem: that it turns the cash program and the acquired businesses into operating profit closer to the net income the low multiple is computed on. Adjusted EBITDA is the measure to watch. On the July 30 call, management said it would update its 2026 guide after the Lhoist deal closed, and the deal closed on August 21.
