Meridian Bioscience : 2021 Virtual Shareholders Meeting - Rules of Conduct and Procedures

ANNUAL MEETING OF SHAREHOLDERS

January 27, 2021

RULES OF CONDUCT AND PROCEDURES

Welcome to the Annual Meeting of Shareholders (the "Annual Meeting") of Meridian Bioscience, Inc. (the "Company"). It is our desire to conduct a fair and informative Annual Meeting. Kindly observe the following procedural rules and guidelines:

General Guidelines:

1. Because this is a meeting of our shareholders, only our shareholders are permitted to ask questions during the Annual Meeting. You need to have held stock as of the close of business on the record date of December 3, 2020 to vote or submit questions while participating in the virtual Annual Meeting.
2. To vote or submit questions, please log in as a shareholder by entering the 16-digit control number you received with your notification of this meeting and proxy materials. If you have voted your shares prior to the start of the Annual Meeting, your vote has been received by the Company's inspector of elections and there is no need to vote those shares during the Annual Meeting, unless you wish to revoke or change your vote.
3. Dave Phillips, Chairman of the Board of Directors, will strictly follow the agenda outlined below in conducting the meeting.

Question & Answer Period

4. Prior to the Annual Meeting, any shareholder with questions about the items listed for voting on the proxy card may contact Investor Relations at 513-271-3700 or [e-mail]. If we receive any questions about these items, we will address them before the voting polls close.

1. Following adjournment of the formal business of the Annual Meeting, the Company's management will address any other appropriate questions from shareholders. Along with the required shareholder's name and email address, such questions may be submitted in the field provided in the web portal during the Annual Meeting.
2. To allow us to answer questions from as many shareholders as possible, we will limit each shareholder to two questions. It will help us if questions are succinct and cover only one topic per question. Questions from multiple shareholders on the same topic or that are otherwise related may be grouped, summarized and answered together.
3. Shareholder questions are welcome, but conducting the business set out in the Agenda for the benefit of all shareholders will be paramount. The Company does not intend to address any questions that are, among other things:
4. • irrelevant to the business of the Company or to the business of the Annual Meeting;
   • related to material non-public information of the Company;
   • related to personal grievances;
   • derogatory references to individuals or that are otherwise in bad taste;
   • repetitious statements already made by another shareholder;
   • in furtherance of the shareholder's personal or business interests; or
   • out of order or not otherwise suitable for the conduct of the Annual Meeting as determined by the Chair or Corporate Secretary.
5. If there are any matters of individual concern to a shareholder and not of general concern to all shareholders, or if a question posed was not otherwise answered, such matters may be raised separately after the Annual Meeting by contacting Investor Relations at 513.271.3700 or [e-mail].
6. Recording of the Annual Meeting is prohibited. 24 hours after the meeting, a webcast playback will be available at:
