Second Amendment to December 2024 Senior Secured Convertible Promissory Notes

On May 11, 2026, Clene Inc. (the “Company”) entered into the second amendment (the “Second Amendment”) to the amended and restated senior secured convertible promissory notes (the “Amended Notes”) with Kensington Clene 2024, LLC (“Kensington”), 4Life Research, LLC (“4Life”) and La Scala Investments, LLC (“La Scala,” and collectively with Kensington and 4Life, the “Holders”). The Amended Notes were issued on December 20, 2024 and previously amended on August 13, 2025. Pursuant to the Second Amendment, (i) the maturity date was extended to the earlier of (A) August 13, 2027 or (B) a change in control as defined in the Second Amendment (the “Maturity Date”); and (ii) monthly aggregate principal and accrued interest payments of $1,000,000 per month, which were scheduled to commence on September 13, 2026, were deferred, with the full balance of principal and accrued interest due on the Maturity Date.

The other material terms of the Amended Notes remain effective as described in the Company’s Current Reports on Form 8-K filed with the SEC on December 20, 2024, and August 14, 2025.

The foregoing description of the Second Amendment does not purport to be complete and is qualified in its entirety by reference to the text of the Second Amendment, which was filed as Exhibit 10.5 to the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2026, filed with the SEC on May 14, 2026, and is incorporated herein by reference.

The Holders have pre-existing relationships with the Company. Kensington is controlled by Alison Mosca, an independent director of the Company. The Company has license and supply agreements with 4Life, through which it licenses and sells non-pharmaceutical products. Additionally, the co-founder and chairman of the board of directors of 4Life, David Lisonbee, is a member of the board of directors of Clene Nanomedicine, Inc., a wholly-owned subsidiary of the Company. La Scala is also controlled by Mr. Lisonbee.
