Exhibit 99.1

Gorilla Technology H1 Revenue Surges 99% to

US$78.4 Million; Raises FY2026 Revenue Outlook to

at Least US$200 Million

London, United Kingdom – (Newsfile Corp. – August 24, 2026) – Gorilla Technology Group Inc. (NASDAQ: GRRR) (“Gorilla” or the “Company”), a global solution provider in Security Intelligence, Network Intelligence, Business Intelligence, IoT technology and data centres, today announced its unaudited financial results for the six months ended June 30, 2026.

Gorilla delivered a significant acceleration in revenue and a marked sequential improvement in reported operating performance during the second quarter. The outperformance was principally driven by earlier-than-anticipated delivery across multiple contracted customer programmes, enabling the Company to recognize the associated revenue ahead of its original expectations. This was complemented by continued execution across Gorilla’s broader portfolio.

Comparative financial performance

Statement from Jay Chandan, Chairman and Chief Executive Officer

“This is the clearest evidence yet that Gorilla has entered a different phase of scale.” Said Jay Chandan, Chairman & CEO.

“In one year we managed to nearly double our first half revenue to US$78.4 million. Our second quarter revenue increased 78% sequentially and 138% year-on-year to US$50.1 million, while our reported operating loss narrowed by approximately 85% compared with Q1.

The progression matters. In the first half, we absorbed a significant share-based compensation charge largely tied to services rendered prior to 2025 and other significant accounting effects. With their removal during the first half of 2026, we are poised for an improvement in operating results.

We are now converting years of preparation into delivery at scale. We are investing in hardware, infrastructure, people and execution capacity because we see a substantial opportunity ahead of us. Infrastructure cannot be switched on like a tap. Equipment must be procured, installed, commissioned and integrated. Customers must migrate workloads and utilisation must then progress toward steady-state levels.

That investment is happening now. During H1, Gorilla deployed approximately US$14.1 million for the acquisition of property and equipment, while property and equipment, including capital work-in-progress, reached approximately US$29.4 million at June 30, 2026. We are building the capacity and delivery platform required to support a much larger business. Our priorities for the remainder of 2026 are unambiguous: bring more capacity into service, increase utilisation, expand the workloads we deliver for existing customers and convert additional demand into revenue. We are on track to meet previously announced delivery timelines. The objective is not simply to deploy hardware. It is to build long-term customer relationships around infrastructure, compute and associated services.”

Statement from Bruce Bower, Chief Financial Officer

“The first-half results demonstrate both the scale of Gorilla’s investment and the improvement in cash efficiency,” said Bruce Bower, Chief Financial Officer.

“On an IFRS basis, Gorilla reported an operating loss of approximately US$47.2 million and a net loss of approximately US$46.9 million. Adjusted EBITDA was a loss of approximately US$14.6 million, and adjusted net loss was approximately US$15.6 million. The reconciliation included below provides investors with the individual adjustments and their respective treatment.”

“H1 revenue increased 99.3%, while net cash used in operating activities declined by approximately US$8.2 million, or 65.3%, to US$4.3 million. Put simply, we nearly doubled revenue while reducing operating cash usage from 31.8% to 5.5% of revenue.”

“This improvement was achieved while Gorilla deployed approximately US$14.1 million during H1 for the acquisition of property and equipment. Cash deployment may increase as we fund equipment purchases, project-related deposits, construction and commissioning activities. These expenditures represent the planned conversion of liquidity into productive infrastructure and delivery capacity intended to support future revenue—not a weakening of our underlying operating discipline.”

“The Company recorded an overall increase in cash of approximately US$79.8 million during H1, driven principally by financing inflows and supported by customer collections. We closed the period with approximately US$179.4 million in cash. As this liquidity is deployed, our cash balance may fluctuate as we fund existing projects and build the capacity required to support future revenue.”

“We are investing ahead of the revenue and utilisation curve, but we are doing so from a position of substantial liquidity. Our priorities remain disciplined capital allocation, project execution, improved utilisation and the conversion of infrastructure investment into sustainable revenue and cash flow.

“Infrastructure investment and the path to steady state

Gorilla’s current financial profile reflects the deliberate acceleration of its AI infrastructure strategy.

Infrastructure projects require capital to be deployed before their full revenue and margin potential can be realized. Hardware procurement is followed by installation, commissioning, integration, customer onboarding, workload migration and utilisation growth. Consequently, expenditure and accounting recognition may precede steady-state revenue generation.

The Company’s priorities for the second half of 2026 are to:

Financial Outlook

Gorilla is increasing its Q3 2026 revenue planning range to approximately US$48 million to US$50 million, compared with its previous planning range of US$36 million to US$40 million. Gorilla now expects revenue for the 2026 fiscal year of at least US$200 million, raising the minimum from its previously announced range of US$160 million to US$200 million.

2027 guidance

Gorilla is targeting a revenue range of US$450 to US$500 million in 2027, with substantial gross margin improvement.

This objective is supported by the infrastructure being installed in connection with previously disclosed projects, the opportunity to increase utilisation, the potential to expand existing customer relationships and Gorilla’s pipeline of additional demand. The objective remains subject to execution, customer demand, deployment schedules and prevailing market conditions.
