#### Questions and Answers About the Meeting

#### Q:

#### What is "householding"?
A: In order to reduce expenses, we are taking advantage of certain SEC rules, commonly known as "householding," that permit us to deliver, in certain cases, only one Notice, Annual Report, or Proxy Statement, as applicable, to multiple shareholders sharing the same address, unless we have received contrary instructions from one or more of the shareholders. If you received a householded mailing this year and would like to have additional copies of the Notice, the 2024 Annual Report, Proxy Statement, or other proxy materials sent to you, please submit your request directed to our Corporate Secretary, Arcosa, Inc., 500 N. Akard St., Suite 400, Dallas, TX 75201, or by telephone at 972-942-6500. If you hold your stock in street name, you may revoke your consent to householding at any time by notifying your broker.

If you are currently a shareholder sharing an address with another of our shareholders and wish to have your future proxy statements and annual reports householded, or your materials are currently householded and you would prefer to receive separate materials in the future, please contact our Corporate Secretary at the above address or telephone number.
