SIFCO INDUSTRIES, INC.
2026 Annual Meeting of Shareholders
Rules of Conduct

Welcome to the 2026 Annual Meeting of Shareholders of SIFCO Industries, Inc. This
year, our Annual Meeting is taking place in a virtual-only format but we have strived to ensure
that participating shareholders are provided the same rights that they would have had at an in-person meeting and an enhanced opportunity for participation. In fairness to all participants and
in the interest of an orderly and constructive meeting, the following Rules of Conduct will be
enforced:

1. All attendees must register by 11:59 PM ET on January 27, 2026 in order to participate in
or vote at the Annual Meeting. Only shareholders and their properly authorized proxies
that have properly registered to attend the Annual Meeting will be permitted to
participate in or vote at the Annual Meeting. A shareholder who holds shares in “street
name” (that is, through a bank, broker or other nominee) must also register to participate
in or vote at the Annual Meeting and will be required to upload or email a copy of the
legal proxy obtained from such shareholder’s bank or broker in connection with such
registration.

2. Only shareholders of record as of December 5, 2025 or their duly authorized proxies are
entitled to vote. You need not vote at this meeting if you have already voted by proxy. If
you wish to change your vote or if you have not voted, you will be given the opportunity
to do so during the meeting. Registered Shareholders will need the virtual control
number provided on their proxy card in order to vote.

3. Failure to have timely submitted a proposal will cause it to be out of order and bar it from
consideration. Such proposals may be submitted in advance of our next annual meeting
of shareholders.

4. Only shareholders of record as of December 5, 2025 or their duly authorized proxies are
entitled to submit questions and vote at the Annual Meeting. No one may address this
meeting unless recognized by the Chairperson, Alayne Reitman.

5. Shareholders participating in the Annual Meeting live via webcast may also submit
questions in writing during the Annual Meeting. Questions can be submitted by typing
such questions into the Questions/Chat pane of the control panel.

6. Appropriate questions submitted by shareholders will be read following the applicable
agenda item or during the question and answer portion of the Annual Meeting unedited;
however, if multiple questions are submitted on the same topic, we will summarize and
respond collectively. Please keep questions succinct and to a single topic in order to
allow the Company to answer as many questions as possible. Depending on the number
of questions submitted, we may not be able to answer all questions during the Annual
Meeting.

7. To promote fairness and efficient use of the Company’s resources, we will respond to no
more than two questions from any single shareholder.

8. The views of shareholders are welcome, but conducting the business set out in the
Agenda will be paramount. During the meeting, we will not address questions, that are,
among other things:

    • Not related to the matters set forth in the Agenda or otherwise properly brought before the meeting;
    • Do not relate directly to the business of the Company;
    • Disorderly;
    • Repetitious statements already made by other persons;
    • In furtherance of the speaker’s personal or business interests; or
    • Are not a matter of interest to shareholders generally.

9. In order that the business of the meeting be accomplished in a timely manner, discussion
of each proposal will be limited to a total of ten (10) minutes, unless the Chairperson of
the meeting determines otherwise.

10. The Chairperson of the meeting will decide all procedural issues regarding conduct of the
meeting, including adjournment
