On December 16, 2025, CNS Pharmaceuticals, Inc. (the “Company”) entered into an employment agreement (the “Employment Agreement”) with Rami Levin to serve as the Company’s Chief Executive Officer and President effective January 1, 2026. The Employment Agreement provides for an initial annual base salary of $580,000, eligibility for an annual bonus with a target equal to 50% of base salary based on goals approved by the Compensation Committee, and eligibility for annual equity grants under the Company’s stock incentive plans, in each case as determined by the Compensation Committee of the Board of Directors. The Employment Agreement also provides for an initial grant of 19,000 restricted stock units, vesting as follows: 25% on the six-month anniversary of the effective date, 25% on the twelve-month anniversary of the effective date, and the remaining 50% in twelve quarterly installments thereafter, subject to continued employment. Mr. Levin is entitled to participate in the Company’s benefit plans and programs for similarly situated executives, expense reimbursement in accordance with Company policy, and other standard benefits.

Under the Employment Agreement, if Mr. Levin’s employment is terminated by the Company without cause (and other than due to death or disability) or by Mr. Levin for good reason, he will be entitled to (i) severance equal to twelve months of base salary, payable over twelve months, (ii) his target annual bonus for the period of time between the end of the last fiscal year and the termination date; and (iii) accelerated vesting of all unvested equity previously granted, in each case subject to his timely execution and non-revocation of a release of claims and continued compliance with applicable covenants.

On December 16, 2025, the Board of Directors agreed to appoint Mr. Levin as a member of the Company’s Board of Directors as of January 1, 2026.

Mr. Levin, age 56, has served as a Board Advisor for GENerX Life, a life sciences search firm, since November 2024, and as Founder and Chief Executive Officer of The Outcomes Group, a privately held advisory and leadership-development firm, since January 2024.
