 common stock voted as you instructed in a previously delivered proxy. What does it mean if I receive more than one proxy form? It means that you have multiple holdings reflected in our stock transfer records and/or in accounts with stockbrokers. Please sign and return ALL proxy forms to ensure that all your shares are voted. If I hold shares in “street name” through a bank, broker or other nominee, how do I vote? If you hold your shares in street name and you received this proxy statement from your bank, broker or other nominee (collectively, a “broker”), your broker will provide you with instructions for voting your shares. The availability of online voting during the meeting may depend on the voting procedures of the broker that holds your shares. If you have any questions about voting or your control number, please contact the broker that holds your shares. What if I change my mind after I return my proxy? If you are a stockholder of record, you may revoke your proxy and change your vote at any time before the polls close at the annual meeting. You may do this by:

| ● | timely delivering a new valid proxy bearing a later date either by mail or electronic vote over the Internet, or |

| ● | timely sending notice to our Stockholder Relations Manager, Shirley Cantrell, at Old Second Bancorp, Inc., 37 S. River St., Aurora, Illinois 60507, that you are revoking your proxy, or |

| ● | attending the meeting and voting via the Internet during the live audio webcast of the meeting. |

If you hold your shares in street name and desire to revoke your proxy, you will need to contact your broker to revoke your proxy or change your vote. What is a broker non-vote? If you hold your shares in street name, your brokerage firm may vote your shares under certain circumstances. Brokerage firms have authority under stock exchange rules to vote their customers’ unvoted shares on certain “routine” matters. We expect that brokers will be allowed to exercise discretionary authority for beneficial owners who have not provided voting instructions ONLY with respect to Proposal 6, the ratification of Plante & Moran, PLLC as our independent registered public accounting firm for the year ending December 31, 2025, but not with respect to any of the other proposals to be voted on at the annual meeting. If you hold your shares in street name, please provide voting instructions to your broker so that your shares may be voted on all other proposals.
