Explanatory Note

On June 2, 2026, Gorilla Technology Group Inc., a Cayman Islands exempted company (the “Company”), entered into a securities purchase agreement (the “Purchase Agreement”) with certain investors relating to the issuance and sale of $107,000,000 aggregate principal amount of the Company’s 7.50% Senior Unsecured Convertible Notes due 2031 (the “Notes” and such offering, the “Offering”). The Notes are convertible into ordinary shares of the Company, par value $0.001 per share (the “Ordinary Shares”), at an initial conversion rate of 39.2425 Ordinary Shares per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $25.4826 per Ordinary Share), subject to adjustment as described in the Indenture (as defined below). The Notes will mature on June 15, 2031, unless earlier converted, redeemed or repurchased, and will bear interest at a rate of 7.50% per annum, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on December 15, 2026. Interest on the Notes is payable, at the Company’s election, in cash or Ordinary Shares, in each case subject to the terms and conditions set forth in the Indenture. The Purchase Agreement contains customary representations and warranties, conditions to closing, termination provisions and indemnification obligations, including for liabilities under the Securities Act of 1933, as amended.

The Notes were issued pursuant to an indenture, dated as of June 5, 2026 (the “Indenture”), by and between the Company and U.S. Bank Trust Company, National Association, as trustee, paying agent, registrar and conversion agent. The Indenture sets forth the terms of the Notes, including the conversion rights, redemption and repurchase rights, covenants, events of default and other provisions governing the Notes.

The closing of the Offering occurred on June 5, 2026 and the Company received net proceeds of approximately $102.4 million, after deducting placement agent fees but before paying estimated offering expenses. The Offering was made pursuant to the shelf registration statement on Form F-3 (File No. 333-274053) previously filed by the Company with the Securities and Exchange Commission (the “SEC”) on August 17, 2023 and declared effective by the SEC on August 29, 2023, and a related registration statement on Form F-3 filed pursuant to Rule 462(b) under the Securities Act (File No. 333-296439) filed with the SEC on June 2, 2026.

The Benchmark Company, LLC (“Benchmark”) and StoneX Financial Inc. (“StoneX”) acted as our exclusive placement agents for the Offering (the “Placement Agents”).

On June 2, 2026, the Company also entered into a Placement Agency Agreement with Benchmark (the “Placement Agency Agreement”), pursuant to which the Benchmark appointed StoneX as a co-placement agent and the Placement Agents acted as the exclusive placement agents for the Company in connection with the Offering. The Company agreed to pay the Placement Agents a cash fee equal to (i) five percent (5.0%) of the initial $50,000,000 of the gross proceeds from the Offering, (ii) three and one-half percent (3.5%) of gross proceeds in excess of $50,000,000 up to and including $100,000,000 and (iii) two and one-half percent (2.5%) of gross proceeds in excess of $100,000,000. In addition, the Company agreed to reimburse the Placement Agents for up to $150,000 of its fees and expenses in connection with the Offering. The Placement Agency Agreement contains customary representations, warranties, and agreements by the Company, customary conditions to closing, indemnification obligations of the Company, other obligations of the parties, and termination provisions.

In connection with the Offering, the Company and the directors and executive officers of the Company entered into lock-up agreements (the “Lock-Up Agreements”), which each provide for a 120-day lockup period, subject to customary exceptions.

The foregoing descriptions of the Purchase Agreement, the Indenture, the Notes, the Placement Agency Agreement and the Lock-Up Agreements do not purport to be complete and are qualified in their entirety by reference to the full text of the Purchase Agreement, the Indenture, the form of Note, the Placement Agency Agreement and the form of Lock-Up Agreement, which are filed as Exhibits 99.1, 99.2, 99.3, 99.4 and 99.5, respectively, to this Report of Foreign Private Issuer on Form 6-K and are incorporated by reference herein.
