Private Placement, Management Change/Compensation (Form 8-K)

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

On April 20, 2026, the Board of Directors (our "Board") of ALT5 Sigma Corporation (the "Company", "we", "our", or "us") approved an employment agreement (the "Employment Agreement") for our Chief Executive Officer, Tony Isaac. In connection with our Board's action, Mr. Isaac's title was changed from "Acting Chief Executive Officer" to "Chief Executive Officer."

The Employment Agreement provides for a three-year term, subject to annual renewals, unless either party provides written notice of non-renewal at least 90 days prior to the expiration of the initial term or any renewal term. Mr. Isaac's annual base compensation is $600,000. Mr. Isaac is also eligible for an annual bonus in the sole and absolute discretion of our Compensation Committee. In addition, we issued to Mr. Isaac five million shares of our common stock, the periodic releases of which are determined by the price of our common stock (the "Stock Award"). In the event that Mr. Isaac's employment with us terminates because he elects not to renew the Employment Agreement, terminates for good reason, or we terminate him without cause (as those concepts are more fully described in the Employment Agreement), we shall pay to Mr. Isaac (i) any accrued but unpaid base salary and accrued but unused vacation, (ii) any unpaid annual bonus, if awarded by our Compensation Committee, (iii) any unreimbursed business expenses, and (iv) any other employee benefits to which he may be entitled under our employee benefit plan. Further, in those circumstances and upon Mr. Isaac executing a release in our favor, we shall also pay him an amount equal to the sum of his base salary and potential annual bonus for that termination year and all of Mr. Isaac's equity or other awards shall then vest.

Upon a termination of the Employment Agreement in connection with a change of control of the Company (as described in our 2024 Equity Incentive Plan), we shall pay Mr. Isaac (i) an amount equal to three times the sum of his base salary and potential annual bonus amount for the year in which the termination event occurs (or, if greater, the year immediately preceding the year in which the change of control occurs) and (ii) an amount equal to his potential annual bonus for the year in which the termination event occurs (or, if greater, the year in which the change of control occurs). Finally, upon such termination, all restrictions in respect of the Stock Award shall be released.
