Appendix 3 2025 Financial Statements

Independent Auditors' Report Translated from Chinese

To SINBON Electronics Co., Ltd.

Opinion

We have audited the accompanying consolidated balance sheets of SINBON Electronics Co., Ltd. (the "Company") and its subsidiaries as of 31 December 2025 and 2024, and the related consolidated statements of comprehensive income, changes in equity and cash flows for the years ended 31 December 2025 and 2024, and notes to the consolidated financial statements, including the summary of material accounting policies (together "the consolidated financial statements").

In our opinion, based on our audits and the report(s) of the other auditors (please refer to the Other Metter – Making Reference to the Audits(s) of Other Auditors section of our report), the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company and its subsidiaries as of 31 December 2025 and 2024, and their consolidated financial performance and cash flows for the years ended 31 December 2025 and 2024, in conformity with the requirements of the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Financial Reporting Standards, International Accounting Standards, Interpretations developed by the International Financial Reporting Interpretations Committee or the former Standing Interpretations Committee as endorsed and became effective by Financial Supervisory Commission of the Republic of China.

Basis for Opinion

We conducted our audits in accordance with the Regulations Governing Financial Statement Audit and Attestation Engagements of Certified Public Accountants and the Standards on Auditing of the Republic of China. Our responsibilities under those standards are further described in the Auditors' Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are independent of the Company and its subsidiaries in accordance with the Norm of Professional Ethics for Certified Public Accountant of the Republic of China (the "Norm"), and we have fulfilled our other ethical responsibilities in accordance with the Norm. Based on our audits and the report(s) of the other auditors, we believe that the audit evidence we


have obtained is sufficient and appropriate to provide a basis for our opinion.

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of 2025 consolidated financial statements. These matters were addressed in the context of our audit of the consolidated financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

1. Valuation for inventories

As of 31 December 2025, the Company and its subsidiaries net inventories amounted to NT$7,956,380 thousand. Net inventories accounted for 25% of consolidated total assets, which was considered material in the consolidated statements. As the fluctuation in market demand and the fast-changing technology could cause losses of obsolete and slow-moving inventories, the assessment of the inventory write-downs require significant management judgment. We therefore determined this a key audit matter.

Our audit procedures included, but not limited to, understanding and testing the adequacy of accounting policy around obsolete and slow-moving inventories; evaluating stocktaking plan and selecting important storage locations to observe inventory counts to ensure inventory quantities and status; obtaining inventory aging schedule to test whether inbound and outbound records are accurate; re-calculating the unit cost of inventories; and evaluating and testing net realizable value adopted by management. We also assessed the adequacy of disclosures of financial assets. Please refer to Notes 5 and 6 to the Company and its subsidiaries consolidated financial statements.

2. Impairment of accounts receivable

As of 31 December 2025, gross accounts receivable and loss allowance by the Company and its subsidiaries amounted to NT$7,454,173 thousand and NT$14,207 thousand, respectively. Net accounts receivable accounted for 23% of consolidated total assets. Since the loss allowance of account receivables is measured by the expected credit loss for the duration of the account receivables, it is necessary to divide account receivables into groups in the process of measurement and analyze the application of related assumptions, including appropriate aging intervals and their respective loss rate. As the measurement of expected credit loss involves making

17


judgment, analysis and estimates, and the result will affect the net account receivable, we therefore determined this a key audit matter.

Our audit procedures included, but not limited to, analyzing the appropriateness of the grouping of account receivables and confirming whether customers with significantly different credit loss types are grouped by similar risk characteristics. Testing the provision matrix, including evaluating the appropriateness of the aging intervals and the accuracy of the basic data by reviewing the original certificates; testing the related statistics information of loss rate based on the rolling rate within one year. We also assessed the adequacy of disclosures of financial assets. Please refer to Notes 5 and 6 to the Company and its subsidiaries consolidated financial statements.

Other Matter– Making Reference to the Audit(s) of Other Auditors

As explained in Note 4(3), we did not audit the financial statements of certain consolidated subsidiaries, which statements reflected total assets of NT$1,088,166 thousand and NT$5,047,863 thousand, constituting 3% and 16% of consolidated total assets as of 31 December 2025 and 2024, respectively, and total operating revenues of NT$787,624 thousand and NT$9,113,485 thousand, constituting 3% and 28% of consolidated operating revenues for the years ended 31 December 2025 and 2024, respectively. Those financial statements were audited by other auditors, whose reports thereon have been furnished to us, and our opinions expressed herein are based solely on the audit reports of the other auditors. We did not audit the financial statements of certain associates and joint ventures accounted for under the equity method whose statements are based solely on the reports of the other auditors. As explained in Note 6(7), these associates and joint ventures under equity method amounted to NT$914,078 thousand and NT$908,342 thousand, both representing 3% of the total assets as of 31 December 2025 and 2024. The related shares of profits from the associates and joint ventures under the equity method amounted to NT$225,855 thousand and NT$200,593 thousand, representing 6% and 4% of the net income before tax for the years ended 31 December 2025 and 2024, respectively, and the related shares of other comprehensive income (loss) from the associates and joint ventures under the equity method amounted to NT$(63,871) thousand and NT$(22,172) thousand, representing 49% and (8)% of the consolidated other comprehensive income (loss) for the years ended 31 December 2025 and 2024, respectively.

Responsibilities of Management and Those Charged with Governance for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with the requirements of the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Financial Reporting Standards, International Accounting Standards, Interpretations developed by the International Financial Reporting Interpretations Committee or the former Standing Interpretations Committee as endorsed by

18


Financial Supervisory Commission of the Republic of China and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is responsible for assessing the ability to continue as a going concern of the Company and its subsidiaries, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Company and its subsidiaries or to cease operations, or has no realistic alternative but to do so.

Those charged with governance, including audit committee or supervisors, are responsible for overseeing the financial reporting process of the Company and its subsidiaries.

Auditors’ Responsibilities for the Audit of the Consolidated Financial Statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors’ report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the Standards on Auditing of the Republic of China will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with the Standards on Auditing of the Republic of China, we exercise professional judgment and professional skepticism throughout the audit. We also:

  1. Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or

19


the override of internal control.

  1. Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the internal control of the Company and its subsidiaries.

  2. Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.

  3. Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the ability to continue as a going concern of the Company and its subsidiaries. If we conclude that a material uncertainty exists, we are required to draw attention in our auditors’ report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditors’ report. However, future events or conditions may cause the Company and its subsidiaries to cease to continue as a going concern.

  4. Evaluate the overall presentation, structure and content of the consolidated financial statements, including the accompanying notes, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

  5. Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Company and its subsidiaries to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and to

20


communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of 2025 consolidated financial statements and are therefore the key audit matters. We describe these matters in our auditors' report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

Other

We have audited and expressed an unqualified opinion including an Other Matter Paragraph on the parent company only financial statements of SINBON Electronics Co., Ltd. as of and for the years ended 31 December 2025 and 2024.
