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

On November 7, 2025, in connection with Michael Edell’s previously announced appointment as our Interim Chief Operating Officer, we entered into an employment offer letter agreement with Mr. Edell (the “Employment Agreement”) to serve as our Interim Chief Operating Officer, effective November 3, 2025 (the “Commencement Date”).

Under the terms of the Employment Agreement, Mr. Edell will receive $30,000 per month, less applicable taxes and withholdings. Mr. Edell will be eligible to receive bonuses, subject to the discretion and approval of our Board of Directors, for (i) Q4 of 2025 in an amount up to $25,000, and (ii) Q1 of 2026 in an amount up to $30,000. No other forms of compensation, including additional bonuses, commissions, or equity awards, will be provided unless specifically authorized in writing by us. Given the interim and at-will nature of Mr. Edell’s role, Mr. Edell will not be eligible for company-sponsored benefits, including but not limited to health insurance, retirement plans, paid time off, or other fringe benefits, except as required by California law.

During the term of the employment with us, Mr. Edell will be restricted from competing with our business.

The Employment Agreement is effective as of the Commencement Date and will continue for a period of six months thereafter, unless sooner terminated. Mr. Edell’s employment is strictly at-will, however, we must provide Mr. Edell 60 days’ advance written notice (the “Notice Period”) for a termination without Cause (as defined in the Employment Agreement). We may, in our sole discretion, choose to relieve Mr. Edell of his duties for us immediately, but Mr. Edell will remain an employee and continue to be paid his regular salary during the Notice Period. Mr. Edell may also terminate his employment for any reason upon 60 days’ advance written notice. Except as otherwise provided in the Employment Agreement, Mr. Edell will not be entitled to, nor eligible for, any severance pay, separation pay, or any other post-termination compensation.

The description of the Employment Agreement set forth above does not purport to be complete and is qualified in its entirety by the full text of the Employment Agreement, a copy of which is attached hereto as Exhibit 10.1 and is incorporated herein by reference.
