EXPLANATORY NOTE

On October 14, 2026, TNL Mediagene (the “Company”) received a letter from the Office of the General Counsel of The Nasdaq Stock Market LLC (“Nasdaq”) confirming that the Company has regained compliance with Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Rule”), as required by the decision of the Nasdaq Hearings Panel (the “Panel”) dated August 23, 2026 (the “Decision”).

As previously reported in the Company’s Report of Foreign Private Issuer on Form 6-K furnished to the U.S. Securities and Exchange Commission (the “SEC”) on August 25, 2026, the Panel granted the Company’s request for continued listing on The Nasdaq Capital Market, subject to the Company’s satisfaction of certain conditions. Those conditions include the requirement that, on or before October 30, 2026, the Company demonstrate compliance with Nasdaq Listing Rule 5550(b)(1), which requires listed companies to maintain stockholders’ equity of at least $2,500,000 (the “Equity Rule”). The letter noted that the Company remains non-compliant with the Equity Rule.

The Company intends to take all steps necessary to demonstrate compliance with the Equity Rule on or before October 30, 2026. The Company’s ordinary shares will continue to be listed and traded on The Nasdaq Capital Market under the symbol “TNMG” during the exception period, subject to the Company’s compliance with the terms of the Decision. Any compliance submission by the Company will be subject to review by the Panel. There can be no assurance that the Company will be able to demonstrate compliance with the Equity Rule on or before October 30, 2026, or that the Company will otherwise maintain compliance with the Bid Price Rule or Nasdaq’s other continued listing requirements. If the Company fails to demonstrate compliance with the Equity Rule on or before October 30, 2026, or otherwise fails to satisfy the terms of the Decision, the Company’s securities will be subject to delisting from Nasdaq.

On October 16, 2026, the Company issued a press release announcing its receipt of the letter described above. A copy of the press release is furnished as Exhibit 99.1 to this Report on Form 6-K.
