's NEOs for every ONE year; and (iv) FOR ratification of Ernst & Young as the independent registered public accounting firm of Arcosa for the year ending December 31, 2025.

#### Q:

#### What is a Broker Non-Vote?
A: A "broker non-vote" occurs when a broker submits a proxy for the meeting with respect to a discretionary, or routine, matter but does not have the authority to vote on non-discretionary matters because the beneficial owner did not provide voting instructions on those matters.

Under NYSE rules, the proposal to ratify the appointment of Ernst & Young as the independent registered public accounting firm for the year ending December 31, 2025 (Proposal 4) is considered a "discretionary" or "routine" item. This means that brokerage firms may vote in their discretion on behalf of clients (beneficial owners) who have not furnished voting instructions. In contrast, all of the other proposals set forth in this Proxy Statement are "non-discretionary" or "non-routine" items—brokerage firms that have not received voting instructions from their clients on these matters may not vote on these proposals.

#### Q:

#### Can I change or revoke my vote?
A: If you are a registered shareholder, any subsequent vote you cast will replace your earlier vote. This applies whether you cast your vote by executing a Proxy Card bearing a later date, vote by telephone, internet, or smart phone, or by virtually attending the Annual Meeting and submitting your vote virtually during the Annual Meeting. The proxy may be revoked at any time before it is exercised by filing with Arcosa a written revocation addressed to the Corporate Secretary.

If you hold your shares in street name, you must contact your broker, bank, or other nominee for specific instructions on how to change or revoke your vote.

#### Q:

#### What constitutes a "quorum" for the meeting?
A: The presence, in person or by proxy, of the holders of record of a majority of the outstanding shares entitled to vote is necessary to constitute a quorum for the transaction of business at the Annual Meeting, but if a quorum should not be present, the meeting may be adjourned from time to time until a quorum is obtained.

Q: What is the voting requirement to approve each of the proposals, and how are votes counted?
