Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On September 1, 2025 (the “Effective Date”), the Board of Directors (the “Board”) of Genelux Corporation (the “Company”) approved a reduction in the exercise prices of certain outstanding options to purchase shares of the Company’s common stock (the “Common Stock”) under the Company’s 2022 Equity Incentive Plan (the “2022 Plan”), 2019 Equity Incentive Plan (the “2019 Plan”) and 2009 Equity Incentive Plan (the “2009 Plan” and together with the 2022 Plan and 2019 Plan, the “Plans”) that had exercise prices greater than $5.00 per share as of the Effective Date (the “Eligible Options”). The exercise price for Eligible Options was reduced to $3.33 per share, the closing price of the Common Stock on the Effective Date.

Eligible Options include options granted pursuant to the Plans that are held by employees as of the Effective Date. No reduction in exercise price was made to options held by non-employee directors of the Board or options granted under the Company’s 2023 Inducement Plan. No other terms of Eligible Options were modified, and the options will continue to vest according to their original vesting schedules and will retain their original expiration dates.

The following options held by the Company’s executive officers were included in the reduction of exercise price:

Name and Title	Number of Option Shares	Exercise Price Range of Option Shares Prior to Reduction
Joseph Cappello, Chief Technical Officer	174,999	$6.00 - $22.40
Ralph Smalling, Head of Regulatory	8,333	$6.00
Tony Yu, Senior VP, Clinical Development	272,652	$6.00 - $22.40
Thomas Zindrick, President and CEO	1,355,940	$6.00 - $22.40

After multiple discussions, careful consideration of various alternatives and a review of other applicable factors, including the recommendation of the Compensation Committee of the Board and with the advice of the Board’s independent compensation consultant, the Board determined that the reduction in exercise prices for Eligible Options, which is permitted under the terms of the Plans by approval of the Board, was in the best interests of the Company and its stockholders and provides an effective means of retaining and incentivizing the Company’s employees as of the Effective Date while preserving cash resources and without incurring stock dilution from significant additional equity grants. The total number of shares underlying all Eligible Options is approximately 2,715,583. The Eligible Options previously had exercise prices ranging from $6.00 to $22.40 per share.

5.07 Submission of Matters to a Vote of Security Holders.

On August 27, 2025, the Company held its 2025 Annual Meeting of Stockholders (the “Annual Meeting”). As of June 30, 2025, the record date for the Annual Meeting (the “Record Date”), 37,760,843 shares of the Company’s Common Stock were outstanding and entitled to vote at the Annual Meeting. A summary of the matters voted upon by stockholders at the Annual Meeting is set forth below.

A total of 26,704,149 shares of the Company’s Common Stock were present at the Annual Meeting in person, by virtual attendance or by proxy, which represents approximately 70.72% of the shares of the Company’s Common Stock outstanding as of the Record Date.
