MARTIN MARIETTA COMPLETES ASSET EXCHANGE

WITH QUIKRETE HOLDINGS, INC

**Raleigh, N.C. (February 23, 2026)** – Martin Marietta Materials, Inc. (NYSE: MLM) (Martin Marietta or the Company) today announced the completion of its previously announced asset exchange with Quikrete Holdings, Inc. (QUIKRETE) on February 23, 2026.

Under the terms of the transaction, Martin Marietta acquired aggregates operations producing approximately 20 million tons annually in Virginia, Missouri, Kansas and Vancouver, British Columbia, along with $450 million in cash. In exchange, QUIKRETE acquired the Company's Midlothian cement plant, related cement terminals and Texas ready-mixed concrete assets and certain nonoperating land.

Ward Nye, Chair, President and CEO of Martin Marietta stated, "This portfolio-enhancing transaction establishes new growth platforms in key SOAR-target markets while further strengthening our differentiated Central Division footprint. Through a tax-efficient exchange of cyclical cement and ready-mixed concrete assets for the largest aggregates acquisition in our Company's history, we are enhancing the durability of our earnings while preserving ample balance sheet capacity to extend our long track record of disciplined strategic plan execution and compelling shareholder value creation.

"As the capstone to our SOAR 2025 plan, this transaction accelerates our aggregates-led product strategy and completes a pivotal phase of portfolio transformation, positioning Martin Marietta exceptionally well to pursue core, growth-focused M&A opportunities as we launch SOAR 2030."

Updated 2026 Outlook

The Company's updated 2026 Guidance below reflects continuing operations inclusive of contributions from the QUIKRETE transaction as of the close date and the Minnesota aggregates and FOB asphalt assets acquired from CRH in December 2025.

Asset Exchange Supplemental Information 2 Statement Regarding Safe Harbor for Forward-Looking Statements Investors are cautioned that all statements herein that relate to the future involve risks and uncertainties and are based on assumptions that the Company believes in good faith are reasonable but which may be materially different from actual results. These statements, which are forward-looking statements under the Private Securities Litigation Reform Act of 1995, provide the investor with the Company's expectations or forecasts of future events. You can identify these statements by the fact that they do not relate only to historical or current facts. They 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 operating or financial performance. Any or all of the Company's forward-looking statements here and in other publications may turn out to be wrong. Non-GAAP Financial Measures This material contains financial measures that are not prepared in accordance with United States generally accepted accounting principles (GAAP). The Appendix contains reconciliations of these non-GAAP financial measures to the closest GAAP measures. Management believes these non-GAAP measures are commonly used by investors to evaluate the Company's performance and, when read in conjunction with the Company's consolidated financial statements, present a useful tool to evaluate the Company's ongoing business performance from period to period and anticipated performance. Additionally, these are some of the factors the Company uses in internal evaluations of the overall performance of its businesses. Management acknowledges that many factors impact reported results, and the adjustments in these non-GAAP measures do not account for all such factors. Furthermore, these non-GAAP measures may not be comparable to similarly titled measures used by other companies. Results and Trends Results and trends described in this Supplemental Information may not necessarily be indicative of the Company's future performance.
