Financial Position

GigaMedia maintained its solid financial position, with cash, cash equivalents and restricted cash amounting to $29.4 million as of September 30, 2025, or $2.66 per share.

Business Outlook

The following forward-looking statements reflect GigaMedia's expectations as of October 30, 2025. Given potential changes in economic conditions and consumer spending, the evolving nature of online games, and various other risk factors, including those discussed in the Company's 2024 Annual Report on Form 20-F filed with the U.S. Securities and Exchange Commission as referenced below, actual results may differ materially.

“For the following quarter, GigaMedia will continue the strategies of internally-driven growth by improving productivity of the existing games, executing effective marketing, and pursuing a steady expansion of customer base,” stated GigaMedia CEO James Huang.

In the meantime, we will continue reviewing suitable prospects for strategic investment and acquisition targets to increase corporate growth and maximize shareholder value.

Use of Non-GAAP Measures

To supplement GigaMedia's consolidated financial statements presented in accordance with US GAAP, the Company uses the following measure defined as non-GAAP by the SEC: EBITDA. Management believes that EBITDA (earnings before interest, taxes, depreciation, and amortization) is a useful supplemental measure of performance because it excludes certain non-cash items such as depreciation and amortization and that EBITDA is a measure of performance used by some investors, equity analysts and others to make informed investment decisions. EBITDA is not a recognized earnings measure under GAAP and does not have a standardized meaning. Non-GAAP measures such as EBITDA should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, other financial measures prepared in accordance with GAAP. A limitation of using EBITDA is that it does not include all items that impact the company's net income for the period. Reconciliations to the GAAP equivalents of the non-GAAP financial measures are provided on the attached unaudited financial statements.
