APPENDIX

Earnings Before Interest, Taxes, and Depreciation and Amortization, or EBITDA, is a widely accepted financial indicator of a
company’s ability to service and/or incur indebtedness. EBITDA is not defined by generally accepted accounting principles
and, as such, should not be construed as an alternative to net earnings or operating cash flow. For further information on
EBITDA, including a reconciliation of net earnings attributable to Martin Marietta to consolidated EBITDA, please refer to
the 2018 Annual Report, available at www.MartinMarietta.com.

Adjusted EBITDA excludes the impact of acquisition-related expenses, net; the impact of selling inventory after its markup
to fair value as part of acquisition accounting; and the impact of asset and portfolio rationalization charges. The following
reconciles consolidated EBITDA to adjusted EBITDA:
