EXPLANATORY NOTE

On September 14, 2023, LSI Industries Inc. filed its Definitive Proxy Statement with the Securities and Exchange Commission. The Proxy Statement was filed in connection with our 2023 Annual Meeting of Shareholders to be held on November 1, 2023.

This supplement to the Proxy Statement is being filed to add a fourth proposal inserted as Proposal No. 4, which is an advisory vote on the frequency of holding an advisory vote on the compensation of our named executive officers, which is required by SEC rules to be included every six years regardless of a company’s frequency of holding “say-on-pay” votes historically. We are asking our shareholders to vote, on an advisory and non-binding basis, with respect to the frequency of holding of an advisory vote on executive compensation, as described in this Supplement to Proxy Statement dated October 4, 2023. The Board of Directors recommends that the Company continue to hold such an advisory vote on an annual basis and that the shareholders therefore vote for a frequency of “1 YEAR”.

This Supplement includes (i) the updated Notice of Annual Meeting of Shareholders reflecting the addition of Proposal No. 4; (ii) the Supplement, which adds Proposal No. 4 to the Proxy Statement; and (iii) the amended proxy card to be distributed to the Company’s shareholders reflecting the addition of Proposal No. 4. No other changes are being made to the Proxy Statement.

Supplement to the Proxy Statement for the 2023 Annual Meeting of Shareholders

to be held Wednesday, November 1, 2023

We are furnishing this Supplement to our Proxy Statement in connection with the solicitation of proxies by the Board of Directors of LSI Industries Inc. for our Annual Meeting of Shareholders (the “Annual Meeting”) to be held via live webcast on Wednesday, November 1, 2023, at 9:00 a.m. (Eastern Standard Time), and any adjournment or postponement thereof. Online access is at www.virtualshareholdermeeting.com/LYTS2023. Shareholders of record as of the close of business on September 6, 2023 may vote and participate in the Annual Meeting using the 16-digit control number included in your Notice of Internet Availability of Proxy Materials or on your proxy card or by following the instructions contained in your proxy materials. A Notice of Internet Availability of Proxy Materials was first mailed or delivered on September 14, 2023.

On September 14, 2023, we filed our Proxy Statement relating to the Annual Meeting with the Securities and Exchange Commission and made it available to our shareholders on the Internet. Subsequent to that date, we determined that we had inadvertently omitted the required proposal to shareholders regarding the frequency of future advisory votes regarding the compensation of our named executive officers. This Supplement has been prepared to provide our shareholders with information regarding a new non-binding, advisory vote regarding the frequency with which the Company’s shareholders shall have the advisory, non-binding say-on-pay vote on compensation paid to its named executive officers. This Say-on-Frequency Proposal has been added to the Proxy Statement by this Supplement as Proposal No. 4.

This Supplement is being furnished to our shareholders of record as of the September 6, 2023 record date, pursuant to the accompanying Amended Notice of Annual Meeting of Shareholders. This Supplement and the Amended Notice of Annual Meeting of Shareholders supplement and amend the Notice of Annual Meeting of Shareholders and the Proxy Statement, each dated September 14, 2023, previously made available to our shareholders. This Supplement does not provide all of the information that is important to your decision at the Annual Meeting. Additional information is included in the Proxy Statement that was previously made available to our shareholders. We encourage you to carefully read this Supplement together with the Proxy Statement.

Shareholders of record are receiving the proxy card enclosed with this Supplement that includes the Say-On-Frequency Proposal under Proposal No. 4. Shareholders of record may vote on all four proposals by submitting the proxy card enclosed with this Supplement. Properly executed proxies that do not contain voting instructions for any item will be voted in accordance with the recommendations of the Board.

IT IS IMPORTANT TO INDICATE YOUR VOTE ON EACH PROPOSAL ON THE NEW PROXY CARD.

Except for the addition of Proposal No. 4, this Supplement does not modify, amend, supplement or otherwise affect any matter presented for consideration in the Proxy Statement.

Important Notice Regarding the Availability of Proxy Materials for the Shareholder Meeting to Be Held on Wednesday, November 1, 2023.

The Company’s 2023 Notice of Annual Meeting of Shareholders, as amended, the Company’s 2023 Proxy Statement, this Supplement to Proxy Statement, the form of Proxy Card, and the Company’s Annual Report to Shareholders for the year ended June 30, 2023 are also available at www.lsicorp.com.

PLEASE VOTE — YOUR VOTE IS IMPORTANT

FREQUENCY OF ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION – PROPOSAL NO. 4 ON THE PROXY CARD

In Proposal No. 3, shareholders are asked to cast a non-binding advisory vote with respect to the compensation of our named executive officers which is described in the section titled “Compensation Discussion and Analysis” and in the related compensation tables and narrative discussion in this Proxy Statement. This advisory vote is typically referred to as a “say-on-pay” vote. In this Proposal No. 4, the Board is also asking shareholders to cast a non-binding advisory vote on how frequently say-on-pay votes should be held in the future. Shareholders will be able to cast their votes on whether to hold say-on-pay votes every one, two or three years. Alternatively, you may abstain from casting a vote. The frequency receiving the greatest number of votes will be the frequency recommended by the shareholders. Abstentions and broker non-votes are not considered votes cast for any frequency.

The Board recommends that the advisory vote on executive compensation be held every year. An annual vote will allow our shareholders to provide us with regular input on the important subject of executive compensation and allow the Board and the Compensation Committee to consider any issue of concern to shareholders as promptly as possible. Although the vote on the frequency of advisory votes on executive compensation is not binding, the Compensation Committee and the Board will consider the result of the vote in determining what the frequency will be.

The alternative “1 YEAR,” “2 YEARS,” or “3 YEARS” receiving the greatest number of votes cast by the stockholders, a plurality, will be the stockholders’ non-binding choice as to the frequency of future “say-on-pay” votes. If you hold your shares through a broker, bank, trustee or other nominee and you do not instruct them on how to vote on this proposal, your broker or other nominee will not have authority to vote your shares. Abstentions and broker non-votes will not be counted in determining which alternative received the largest number of votes cast and will not affect the outcome of the vote on this proposal. For the advisory vote on the frequency of the “say-on-pay” vote, you may choose between “1 YEAR,” “2 YEARS,” or “3 YEARS” or abstain from voting.

The Board of Directors of the Company unanimously recommends that you vote for a frequency of “1 Year” on Proposal No. 4.

SOLICITATION OF PROXIES

If you have already voted and do not submit a new (amended) proxy card, your previously submitted proxy will be voted at the Annual Meeting with respect to all other proposals but will be considered an abstention in determining the outcome of Proposal 4. If you sign and return the enclosed proxy card, it will revoke and replace any previous proxy you have submitted, so it is important to indicate your vote on each proposal on the enclosed proxy card.

Your shares will be voted as specified on the enclosed proxy card. If a proxy card is signed without choices specified, those shares will be voted FOR the election of the directors as recommended by the Board, as stated in the Proxy Statement and in the Notice of Internet Availability of Proxy Materials, (Proposal No. 1), FOR the ratification of the Audit Committee’s selection of Grant Thornton LLP as the Company’s independent registered public accounting firm for fiscal year 2024 (Proposal No. 2), FOR the approval on an advisory basis of the compensation of named executive officers (Proposal No. 3), “1 YEAR” for the frequency of the advisory vote on named executive officer compensation (Proposal No. 4), and at the discretion of the proxies on any other matters.

You are encouraged to complete, sign and return the proxy card or vote your shares via the phone or internet even if you expect to participate in the meeting. If you sign a proxy card and deliver it to us, but then want to change your vote, you may revoke your proxy at any time prior to the Annual Meeting by sending us a written revocation or a new proxy.  If you participate in the live webcast, you may revoke your proxy and vote during the virtual meeting.
