Explanatory Note</div>

Gorilla Technology Group Inc. (“Gorilla”
or the “Company”) has been receiving many inquiries regarding its recent contract announcement with Freyr Singapore. To ensure
all shareholders have equal information, the following is additional information regarding this contract that the Company intends to share
in various planned discussions and presentations.

On September 17, 2025, Gorilla announced that
it has signed a US$1.4 billion, three-year contract with Freyr Singapore, an infrastructure platform company, to design, build and operate
a network of AI-powered data centres across Southeast Asia, including Indonesia, Malaysia and Thailand. The $1.4 billion is entirely allocable
to Gorilla, subject to Gorilla satisfying its obligations under the contract. In addition:

| ● | “Phase One” of the programme is valued at US$300 million and execution begins in the fourth quarter 
 of 2025.                                                                                            |

| ● | Gorilla will act as principal operator and AI infrastructure lead, providing full-stack GPU-dense compute, 
 orchestration software and multi-year SLA-based operations.                                                |

| ● | Freyr will serve as the Company’s regional expansion and delivery partner. |

This is a binding contract (not a memorandum of
understanding or framework agreement) and provides immediate revenue visibility from Phase One.

The Company believes current cash on hand and
expected inflows are sufficient to support working capital needs for this and other announced contracts without the need for capital raising
transactions in the short-term.

The press release is furnished as Exhibit 99.1
