Exhibit 99.1

NYSE: MMA – MMA.INC Reduces Annualized Cash Operating Cost Base by Approximately US$1.71 million

Completed actions across workforce, technology and operating infrastructure reduce recurring cash expenditure and strengthen operating leverage

Highlights

New York, NY – SEPTEMBER 10, 2026 – Mixed Martial Arts Group Limited (NYSE American: MMA) (“MMA” or the “Company”), doing business as MMA.INC, today announced that actions completed between January 1, 2025 and June 30, 2026 have eliminated approximately US$1.71 million from its annualized cash operating cost base.

The reductions comprise US$1.54 million in workforce-related cash costs and US$165,000 in technology, operating infrastructure and insurance costs.

All announced reductions relate to recurring cash payments that are no longer required. They are not non-cash accounting adjustments or future cost saving targets.

The actions reduce ongoing cash outflows and, all else being equal, extend the Company’s cash runway.

Cash Operating Cost Reductions

Technology delivery and expanded use of automation, including workflows supported by AI, enabled MMA.INC to streamline selected functions and operate with a leaner organizational structure.

These actions eliminated over US$1.54 million in annualized workforce-related cash costs, comprising US$345,000 in Australian payroll, over US$1 million in international payroll and over US$196,000 in taxes and benefits.

Technology, operating infrastructure and insurance eliminated a further approximately US$165,000 in annualized cash savings. This comprises approximately US$76,600 from deprecating selected Hype functionality and eliminating the associated subscriptions, approximately US$56,500 in insurance savings, and lower online hosting and premises costs.

Nick Langton, Founder and Chief Executive Officer of MMA.INC, said:

“Between January 1, 2025 and June 30, 2026, we removed approximately US$1.71 million from MMA.INC’s annualized cash operating cost base. These are completed reductions embedded in the business, and every dollar represents recurring cash expenditure that is no longer required.

“Technology delivery and automation enabled us to simplify our organizational structure, while additional savings came from Hype functionality deprecation and lower hosting, premises and insurance costs.

“The result is materially less cash leaving the business on a recurring basis, stronger operating leverage and, all else being equal, a longer cash runway.”

MMA.INC continues to review its cash cost structure and operating model and will pursue additional efficiencies where they can be achieved without compromising core revenue generating capabilities or strategic priorities.

Basis of Annualized Cash Operating Cost Reduction Measure

The US$1.71 million figure represents management’s estimate, as of June 30, 2026, of the recurring annual cash expenditure eliminated through actions completed between January 1, 2025 and June 30, 2026. The measure was calculated by annualizing each identified cash cost at the rate applying immediately before that cost was eliminated.

The measure includes payroll, taxes and benefits, premises, online hosting, insurance and subscription costs eliminated through the deprecation of selected Hype functionality. It excludes share-based payments, depreciation, amortization and other non-cash expenses.
