Martin Marietta Materials (MLM) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and Martin Marietta Materials published the results on November 4, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Martin Marietta Materials reports EPS two ways: GAAP, under the accounting rules every US filer follows, and adjusted, continuing operations, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• All figures are for continuing operations. The Midlothian cement plant, cement terminals and Texas ready mixed concrete assets, exchanged with QUIKRETE on February 23, 2026, are reported as discontinued operations. Total diluted EPS including discontinued operations was $3.94, against $6.85 a year earlier.
• Martin Marietta completed its combination with Lhoist North America (LNA) on August 21, 2026, so Q3 2026 includes LNA from that date only. Reportable segments were updated after the QUIKRETE exchange and prior periods recast.

How Martin Marietta Materials splits revenue in its own release, under its own labels, for Q3 2026 against Q3 2025. Indented lines are parts of the line above them.

• Martin Marietta Materials's Aggregates revenue was $1.7 billion in Q3 2026, up 14% from $1.5 billion in Q3 2025, 70% of total revenue.
• Martin Marietta Materials's Other Building Materials revenue was $399 million in Q3 2026, up 14% from $351 million in Q3 2025, 17% of total revenue.
• Martin Marietta Materials's Specialties revenue was $362 million in Q3 2026, up 176% from $131 million in Q3 2025, 15% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

In its Q3 2026 release, Martin Marietta Materials said:

“Based on strong acquisition performance, partially offset by softer heritage demand and inflationary cost pressures, the Company is updating its full-year 2026 guidance.”

“With the closing of LNA, we have updated the midpoints of our full-year 2026 Revenue and Adjusted EBITDA guidance to $7.80 billion and $2.48 billion, respectively, as acquisition contributions are anticipated to more than offset lower near-term expectations for our heritage operations.”

“In 2027, we expect mid- to high-single digit aggregates pricing on a mix-adjusted basis, supported by January 1 pricing actions designed to address inflationary cost pressures.”

Each quarter keeps its own page with the figures as reported, so a link to one stays pointed at the same numbers after the next report.

• Q3 2026 (this page), reported Nov 4, 2026

Martin Marietta's revenue is mostly aggregates: crushed stone, sand and gravel. Aggregates revenues were $1,662 million of the $2,369 million total in Q3 2026, Other Building Materials $399 million, and Specialties $362 million, less $54 million of interproduct sales. Total revenues rose 28% from $1,846 million. (Martin Marietta Q3 2026 earnings release, Nov 4, 2026)

Martin Marietta's aggregates revenue grew on acquired volume while price per ton fell. Shipments rose 15.9 percent to a record 67.1 million tons, with acquisitions more than offsetting a modest decline in organic shipments. The average selling price fell 3.6 percent to $22.41 per ton because acquired operations sell below the company average; organic mix-adjusted ASP rose 2.7 percent. (Martin Marietta Q3 2026 earnings release, Nov 4, 2026)

Specialties revenues jumped to $362 million from $131 million after the Lhoist North America (LNA) combination closed on August 21, 2026, for total consideration of $12.9 billion: $7.0 billion in cash and approximately $5.9 billion of Martin Marietta stock. From the closing date LNA delivered revenues of $216 million. Organic Specialties revenues rose 11 percent. The segment makes high-calcium lime, dolomitic lime, industrial minerals and magnesia-based products for steel, infrastructure, glass and environmental customers.

Martin Marietta's reportable segments are the East Group ($1,020 million of Q3 revenues), the West Group ($987 million) and Specialties. Public infrastructure accounted for 37% of aggregates shipments in 2025, and nonresidential and residential construction combined for 58%.

The QUIKRETE asset exchange, completed February 23, 2026, gave Martin Marietta operations producing approximately 20 million tons of aggregates a year in Virginia, Missouri, Kansas and Vancouver, British Columbia, plus $450 million in cash, in return for its Midlothian cement plant, cement terminals and Texas ready mixed concrete assets. (Martin Marietta Form 10-Q, Q3 2026, Nov 4, 2026)

Martin Marietta's diluted EPS from continuing operations fell 34% to $3.94 in Q3 2026, while adjusted EPS from continuing operations fell 11% to $5.47. The gap is the deal costs the adjusted figure adds back: $1.09 per share of acquisition, divestiture and integration expenses, $0.43 for selling acquired inventory after its markup to fair value, and $0.01 of asset and portfolio rationalization charges. (Martin Marietta Q3 2026 earnings release, Nov 4, 2026)

Financing LNA weighed on earnings below the operating line. Martin Marietta took a $1.5 billion term loan and issued $5.5 billion of senior notes, interest expense rose to $138 million from $59 million, and a $27 million bridge commitment fee was expensed in the quarter even though the bridge was not used. Diluted shares rose to 65.1 million from 60.4 million after stock was issued as part of the LNA consideration. (Martin Marietta Q3 2026 earnings release, Nov 4, 2026; Martin Marietta Form 10-Q, Q3 2026, Nov 4, 2026)

Martin Marietta's effective income tax rate for continuing operations was 21.2% for the first nine months of 2026, against 20.0% a year earlier; the 10-Q credits the statutory depletion deduction for mineral reserves as the main reason it sits below the statutory rate. (Martin Marietta Form 10-Q, Q3 2026, Nov 4, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Martin Marietta gives a full-year outlook in its release and updated it in Q3 2026 for LNA. It now guides 2026 revenues of $7,750 million to $7,850 million, Adjusted EBITDA from continuing operations of $2,450 million to $2,500 million, aggregates volume growth of 12.5% to 13.5%, aggregates ASP change of (3.0)% to (2.0)%, and capital expenditures of $590 million to $650 million. (Martin Marietta Q3 2026 earnings release, Nov 4, 2026)

For 2027, Martin Marietta's CEO said he expects mid- to high-single digit aggregates pricing on a mix-adjusted basis from January 1 pricing actions, continued strength in infrastructure and data centers, and softer interest rate-sensitive private construction.

A consensus figure is the average of the models published by the analysts who cover Martin Marietta Materials, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones Martin Marietta Materials's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning MLM is on is MLM a buy or a sell?, what analysts expect next is on the MLM forecast, and what the company does is on the Martin Marietta Materials (MLM) stock page.

Every number on this page can be traced to a document Martin Marietta Materials published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
