Change in Registrant’s Certifying Accountant

On April 30, 2026, Gorilla Technology Group Inc. (the “Company”) appointed UHY LLP (“UHY”) as its independent registered public accounting firm and dismissed Marcum Asia CPAs LLP (“Marcum Asia”) as its independent registered public accounting firm, effective immediately. The appointment of UHY was made after a careful evaluation process undertaken by the Company and was approved by the audit committee of the board of directors of the Company.

Marcum Asia served as the Company’s independent registered public accounting firm from January 31, 2024 to April 30, 2026. The audit report of Marcum Asia on the consolidated financial statements of the Company as of and for the fiscal years ended December 31, 2025 and 2024 did not contain any adverse opinion or disclaimer of opinion and was not qualified or modified as to uncertainty, scope of accounting principles.

In connection with the audit of the Company's consolidated financial statements for the fiscal years ended December 31, 2025 and 2024, and in the subsequent interim period through April 30, 2026, there were no disagreements (as that term is used in Item 16F(a)(1)(iv) of Form 20-F) with Marcum Asia on any matters of accounting principles or practices, financial statement disclosure or auditing scope and procedures which, if not resolved to the satisfaction of Marcum Asia, would have caused Marcum Asia to make reference to such matters in its audit report. Marcum Asia has not conducted an audit of our internal control over financial reporting. There were no other reportable events (as that term is described in Item 16F(a)(1)(v) of Form 20-F) during the fiscal years ended December 31, 2025 and 2024, or in the subsequent period through April 30, 2026.

In accordance with Item 16F(a)(3) of Form 20-F, the Company provided Marcum Asia with a copy of the forgoing disclosure and requested Marcum Asia to furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether or not Marcum Asia agrees with the above statements. A copy of Marcum Asia’s letter, dated May 6, 2026, is filed as Exhibit 99.1 to this Form 6-K.

During the two most recent fiscal years and in the subsequent interim period through April 30, 2026, neither the Company nor anyone on its behalf consulted UHY with respect to (i) the application of accounting principles to a specified transaction, either completed or proposed; or (ii) the type of audit opinion that might be rendered on the Company’s consolidated financial statements, and neither a written report nor oral advice was provided to the Company by UHY that was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue. Additionally, during the two most recent fiscal years and in the subsequent interim period through April 30, 2026, neither the Company nor anyone on its behalf consulted UHY with respect to any matter that was either the subject of a disagreement (as that term is used in Item 16F(a)(1)(iv) of Form 20-F) or a reportable event (as that term is described in Item 16F(a)(1)(v) of Form 20-F).
