Long-term view

Ownership view

Valuation view
MARTIN MARIETTA MATERIALS INC reads 54 out of 100 on Valuation Intelligence, recorded as Reasonable. The stock currently trades below most of its own recent valuation history and above comparable companies. This describes the price being paid relative to the company's financials — it is not a forecast and not a fair value. Valuation Intelligence is a research model and contributes nothing to the Suggested Investment Score or the daily ranking.
Capital returns view
MARTIN MARIETTA MATERIALS INC reads 66 out of 100 on Capital Returns Intelligence (Favorable Capital Returns), reflecting a dividend that has grown about 7.3% a year and a share count falling about 0.7% a year. Capital Returns Intelligence is a research model and contributes nothing to the Suggested Investment Score or the daily ranking.
What changed
No meaningful recorded changes in the stored history.
Risk Intelligence is a core model, Long-Term Potential, Fundamental Momentum, Valuation Intelligence and Capital Returns Intelligence are research models, and Ownership Intelligence is supplemental descriptive evidence. Valuation Intelligence and Capital Returns Intelligence each contribute 0% to the Suggested Investment Score. Nothing here is a recommendation.

Ownership information is publicly reported with a delay; the latest applicable reporting period is 2026-06-30, publicly disclosed 9/11/2026. Congressional activity is unavailable pending legal review and contributes nothing to this reading.

Score explanation
Why this company scores the way it does

How this area is measured

Valuation is inherently uncertain. A stock that appears inexpensive can continue falling, and a stock that appears expensive can continue rising. Valuation Intelligence provides context about the price investors are paying — it does not predict short-term market movements, and it never produces a fair value, a price target or a buy or sell range.

Stored readings only. History builds forward from activation rather than being reconstructed.
Only one stored reading exists for this measure so far, so there is nothing to chart yet.
Why higher yield isn't always better
A very high dividend yield may reflect a falling share price or an unsustainable payout. Capital Returns Intelligence emphasizes consistency and sustainability rather than simply rewarding the highest yield.
Why buybacks can be misleading
Announced or gross buyback spending does not always mean shareholders are gaining ownership. Companies can simultaneously issue shares through employee compensation or acquisitions. Suggested Investments therefore considers actual share-count changes alongside repurchase spending.
What these terms mean
- Dividend Yield
- The annual dividend relative to the current share price.
- Payout Ratio
- The share of company earnings used to pay dividends.
- Free Cash Flow Payout
- How much of the company's available cash is being used for dividends.
- Share Repurchases
- When a company buys back its own stock.
- Dilution
- When the number of shares increases, reducing each existing share's percentage ownership of the company.
- Shareholder Yield
- A combined view of dividends and net share repurchases relative to the company's market value.
Capital Returns Intelligence describes how a company returns capital to shareholders. It is not a measure of stock-price performance, it does not predict future returns, and a strong reading is never a recommendation to buy. Dividends and repurchases can be reduced or stopped at any time. Model CAPITAL_RETURNS_INTELLIGENCE_V1, contributing 0% to the Pro Investor Score.

In the company’s own words
What this company does
Martin Marietta Materials, Inc. (the Company or Martin Marietta) is a leading natural resource-based building materials company. The Company supplies aggregates (crushed stone, sand and gravel) through its network of approximately 400 quarries, mines and distribution yards in 28 states, Canada and The Bahamas. In 2025, aggregates generated 88% of the Company’s total reportable segment gross profit. As of December 31, 2025, Martin Marietta also provides other building materials, namely, cement, ready mixed concrete, asphalt and paving services in targeted markets where the Company has a notable aggregates position. The Company’s heavy-side building materials are used in infrastructure, nonresidential and residential construction projects. Aggregates are also used in agricultural, utility and environmental applications and as railroad ballast. The aggregates, cement, ready mixed concrete, asphalt and paving operations are reported collectively as the "Building Materials business".
The Company also operates a Specialties business (formerly known as the Magnesia Specialties business) with production facilities located in Michigan, Ohio, Nevada, North Carolina, Indiana and Pennsylvania. The Specialties business produces high-purity natural and synthetic magnesia-based products, including magnesium sulfate, magnesium oxide and magnesium hydroxide, that are used in environmental, industrial, agricultural, construction, consumer and specialty applications. The Specialties business also produces dolomitic lime, which is sold primarily to external customers for use in steel production and soil stabilization, and is also used internally as a raw material input in synthetic magnesia production. Specialties’ products are shipped to customers domestically and worldwide.
The Company was formed in 1993 as a North Carolina corporation to succeed the operations of the materials group of the organization that is now known as Lockheed Martin Corporation. An initial public offering of a portion of the Company’s common stock was completed in 1994, followed in 1996 by a tax-free exchange transaction resulting in all of the Company’s common stock becoming publicly traded. Since its initial public offering, the Company has completed over 100 acquisitions, as well as a number of strategic dispositions, strengthening and expanding its aggregates-led presence in the building materials marketplace.
On January 12, 2024, the Company acquired Albert Frei & Sons, Inc., a leading aggregates producer in Colorado. This acquisition added more than 60 years (at current production levels) of high-quality, hard rock reserves, strengthening the Company's aggregates platform in the Denver metropolitan area and improving service to new and existing customers.
