As previously disclosed in Reports on Form 6-K filed by TNL Mediagene (the “Company”), on November 25, 2024 and December 17, 2024, on November 25, 2024, the Company entered a securities purchase agreement for issuance by the Company of a series of senior convertible notes (the “Original Note SPA”) with 3i, LP (the “Note Investor”), and issued and sold a senior convertible note in the aggregate principal amount of $4,722,222 ($4,250,000 with an original issue discount of 10%) (the “Initial Note”) under the Original Note SPA to the Note Investor. The Company has fully repaid the Initial Note on November 11, 2025.

On December 8, 2025, the Company and the Note Buyer entered into an Amendment to the Original Note SPA (the “Amendment”, and the Original Note SPA as amended by the Amendment, the “Note SPA”) to modify certain terms applicable to the issuance of the senior convertible notes to be issued under the Note SPA in the future, including revisions relating to maturity, installment payments, optional prepayment, and acceleration mechanics. Pursuant to the Note SPA, on December 8, 2025, the Company issued to the Note Investor a senior convertible note in the principal amount of US$1,666,667 ($1,500,000 with an original issue discount of 10%) (the “Second Note”). The Amendment and the Second Note include, among others, the following revised terms:

●

a maturity of 18 months from the date of issuance,

●

no installment payments during the initial six (6) months following the date of issuance,

●

the Company’s optional prepayment right subject solely to the make-whole amount and without any additional redemption premium, and

●

a limit on acceleration such that the Note Investor may not accelerate an aggregate amount in excess of 10% of the daily trading volume of the Company’s ordinary shares on any trading day.

The foregoing description of the Amendment and the Second Note does not purport to be complete and is qualified in its entirety by reference to the full text of each such document, forms of which are filed as Exhibit 99.1 and Exhibit 99.2, respectively, to this Report on Form 6-K. The foregoing description of the Note SPA is qualified in its entirety by reference to the full text of such document, form of which is filed as an Exhibit to the Report on Form 6-K filed on November 25, 2024 and incorporated herein by reference.

Issuance of Warrant

The Warrant has a term of five (5) years, with an exercise price equal to 125% of the initial conversion price of the Second Note, subject to customary adjustments. The Warrant may be exercised for cash only at any time that a registration statement covering the resale of the underlying ordinary shares is effective and available; otherwise, the Warrant may be exercised on a cashless basis.
