Item 2.02. Results of Operations and Financial Condition.

On April 10, 2025, Martin Marietta Materials, Inc. (“Martin Marietta” or the “Company”) announced it expects to report first quarter 2025 Revenues, Net Earnings Attributable to Martin Marietta and adjusted EBITDA of $1.353 billion, $116 million and $351 million, respectively. Adjusted EBITDA is a non-GAAP financial measure. See Exhibit A, incorporated by reference herein, for reconciliation to the most directly comparable GAAP measure. These preliminary unaudited results for first quarter 2025 are an estimate, based on information available to management as of the date of this Form 8-K, and are subject to further changes upon completion of Martin Marietta’s quarter-end close procedures.

The Company will provide full first quarter results and full-year outlook during its first-quarter 2025 earnings conference call on Wednesday, April 30, 2025, at 11:00 a.m. Eastern Time. The Company will release full results for the quarter ended March 31, 2025, that morning before the market opens.

A live, listen-only webcast and supplemental information will be accessible on the Investors section of the Company’s website at www.martinmarietta.com. The conference call may also be accessed by dialing +1 (646) 307-1963 and using conference ID 7889725. Please dial in at least 15 minutes in advance to ensure a timely connection to the call. An on-demand replay will be available on the Company’s website approximately two hours following the conclusion of the live broadcast and will be available for one year. Additional information about the Company’s use of non-GAAP financial measures is available on the Company’s website at www.martinmarietta.com by clicking the heading “Reports & Filings” in the “Investors” section and then clicking the quick link “Non-GAAP Measures”.

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On April 9, 2025, James A.J. Nickolas notified Martin Marietta of his decision to resign as Executive Vice President and Chief Financial Officer, effective April 11, 2025 (the “Transition Date”), to join a publicly traded equipment, technology and services company as its Chief Financial Officer. Mr. Nickolas’ resignation is for personal reasons to enable him and his family to relocate to their hometown of Chicago and did not arise from any disagreement on any matter relating to the operations, policies, financial results or accounting practices of the Company.

On April 10, 2025, the Company appointed Robert J. Cardin, age 61, to serve as the Company’s Interim Chief Financial Officer, effective as of the Transition Date, and he will hold the position of Interim Chief Financial Officer until his successor is chosen and qualified. Mr. Cardin will continue to serve as Senior Vice President, Controller and Chief Accounting Officer, a position he has held with the Company since 2019. Mr. Cardin is a Certified Public Accountant and holds a bachelor’s degree from the University of Michigan and a Master’s of Business Administration degree from Wayne State University.

The Company has initiated a search process of internal and external candidates with the assistance of a leading executive search firm to identify the Company’s next Chief Financial Officer.

Exhibit A

MARTIN MARIETTA MATERIALS, INC.

Non-GAAP Financial Measures

Earnings before interest; income taxes; depreciation, depletion and amortization expense; the earnings/loss from nonconsolidated equity affiliates; acquisition, divestiture and integration expenses and the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting subject to the limitations described below; nonrecurring gain on divestiture; and noncash asset and portfolio rationalization charge (Adjusted EBITDA) is an indicator used by the Company and investors to evaluate the Company’s operating performance from period to period. Effective January 1, 2024, transaction expenses and inventory acquisition accounting impacts are only excluded for transactions with at least $2 billion in consideration and transaction expenses expected to exceed $15 million. Management believes Adjusted EBITDA provides investors with a useful tool to evaluate the Company’s ongoing business, performance from period to period and anticipated performance. Adjusted EBITDA is not defined by generally accepted accounting principles and, as such, should not be construed as an alternative to earnings from operations, net earnings attributable to Martin Marietta or operating cash flow. For further information on Adjusted EBITDA, refer to the Company’s website at www.martinmarietta.com.
