MATLIN DAVID J 4

What Happened

• David J. Matlin, a director of Clene Inc. (CLNN), was granted stock options for a total of 5,159 shares on May 21, 2026. The grants are reported as derivative awards (transaction code A) with an exercise price of $6.81 per share. The filing reports an acquisition price of $0.00 because these are option grants, not open-market purchases. The total exercise cost to buy all shares, if and when exercised, would be about $35,133.

Key Details

• Transaction date: May 21, 2026; Form 4 filed May 22, 2026 (timely).
• Grants: 3,659 options vest immediately (Footnote F2); 1,500 options vest in 12 equal monthly installments starting June 21, 2026 (Footnote F1).
• Exercise price: $6.81 per share for both grants.
• Shares owned after transaction: Not disclosed in the Form 4 provided.
• Plan: Awards issued under the Clene Inc. Amended 2020 Stock Plan.
• Reported as derivative awards (A). No 10b5-1 plan, tax-withholding sale, or late-filing indication in this report.

Context

• These are option grants (right to buy shares later at $6.81); immediate vesting of 3,659 options means those can be exercised (subject to plan terms) without further vesting conditions, while the 1,500-options tranche vests monthly over a year.
• Option grants are a common form of compensation for directors and do not by themselves indicate the insider bought or sold underlying shares in the open market.
