Silicon Integrated Systems Corp. Business Report

In 2024, the world entered the post-pandemic recovery phase. However, pressures arising from significantly increased merchant supply from Mainland China, geopolitical tensions, and sluggish consumer demand in Mainland China led to a decline in consumer electronics purchasing willingness. Additionally, excessive inventory accumulation during the pandemic resulted in high stock levels, creating a situation where supply in the overall consumer electronics supply chain far exceeded demand, leading to an extreme imbalance. As an IC design company, the impact of inventory devaluation by customers and weak consumer demand caused our performance to fall short of the expected targets. Nevertheless, due to growth in non-operating income, the net profit after tax for the year 2024 amounted to NT$498 million, with earnings per share of NT$0.81.

Looking ahead to 2025, we will strengthen our engineering services for projected multi-touch capacitive touch chips and capacitive active stylus touch chips, assisting customers in rapidly adopting new solutions using Silicon Integrated chips. This will significantly increase our market share. Additionally, we will accelerate the development of micro-electromechanical microphone chips and solutions, utilizing UMC's process technology to enhance cost competitiveness. After the integration of the original Hycon product line and team, we will leverage the synergies of integrated resources to develop new customers, new applications, and new products. All of these efforts will contribute to further growth in overall revenue.

2024 Business Performance Results of the Business Plan

The Company has established a strong reputation in the consumer electronics, industrial control, and automotive touch product sectors, securing greater demand through faster service. The active stylus chip has already received certification and achieved mass production with leading brand manufacturers and top-tier foundries, making it highly competitive in the market.

The Company's financial condition, profitability and research and development are as follows:

Independent Auditors’ Report Originally Issued in Chinese

To Silicon Integrated Systems Corporation

Opinion

We have audited the accompanying parent company only balance sheets of Silicon Integrated Systems Corporation (“the Company”) as of December 31, 2024 and 2023, and the related parent company only statements of comprehensive income, changes in equity and cash flows for the years ended December 31, 2024 and 2023, and notes to the parent company only financial statements, including the summary of material accounting policies (together “the parent company only financial statements”).

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 Parent Company Only Financial Statements section of our report. We are independent of the Company 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 reports 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 2024 parent company only financial statements. These matters were addressed in the context of our audit of the parent company only financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

Revenue recognition

The Company recognized NT$ 164,568 thousand as net sales for the year ended December 31, 2024. Sales of products is the main operating activity of the Company. Its sale regions include not only Taiwan but also Asia and other regions. Trade terms of sales of products under each sale order may be different. It is necessary for the Company to judge and determine the performance obligations and the timing of its satisfaction under each sale order. As a result, we determined the matter to be a key audit matter.

Our audit procedures include (but are not limited to) evaluating and testing the effectiveness of internal control which is related to the timing of revenue recognition; assessing the appropriateness of the accounting policy for revenue recognition; performing test of details on samples selected; tracing to relevant documentation of transactions, reviewing the significant terms of sale orders and agreements, identifying the performance obligations of the sale orders and agreements and timing of its satisfaction, performing cutoff procedures on selected samples for a period before and after reporting date, tracing to relevant documentation to verify the appropriateness of the timing of revenue recognition, and reviewing significant sales allowance and reversals in subsequent period. Please refer to Note 4 and Note 6 in notes to the parent company only financial statements.

Other Matter – Making Reference to the Audits of Other Auditors

We did not audit the financial statements of certain investee companies, which 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. The investment in these investee companies under equity method amounted to NT$37,407 thousand and NT$77,762 thousand, accounting for 0.3% and 0.4% of total assets as of December 31, 2024 and 2023, respectively. The related shares of losses recognized from these subsidiaries, associates and joint ventures under the equity method amounted to NT$29,513 thousand and NT$66,671 thousand, accounting for (5)% and (11)% of the net income before tax for the years ended December 31, 2024 and 2023 respectively.

Responsibilities of Management and Those Charged with Governance for the Parent Company Only Financial Statements

Management is responsible for the preparation and fair presentation of the parent company only financial statements in accordance with the requirements of the Regulations Governing the Preparation of Financial Reports by Securities Issuers for such internal control as management determines is necessary to enable the preparation of the parent company only financial statements that are free from material misstatement, whether due to fraud or error.

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

Those charged with governance, including audit committee, are responsible for overseeing the financial reporting process of the Company.

Auditors’ Responsibilities for the Audit of the Parent Company Only Financial Statements

Our objectives are to obtain reasonable assurance about whether the parent company only 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 parent company only 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:

Identify and assess the risks of material misstatement of the parent company only 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 the override of internal control.

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.
Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.
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. If we conclude that a material uncertainty exists, we are required to draw attention in our auditors’ report to the related disclosures in the parent company only 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 to cease to continue as a going concern.
Evaluate the overall presentation, structure and content of the parent company only financial statements, including the accompanying notes, and whether the parent company only financial statements represent the underlying transactions and events in a manner that achieves fair presentation.
Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Company to express an opinion on the parent company only 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 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 2024 parent company only 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.

Independent Auditors’ Report Originally Issued in Chinese

To Silicon Integrated Systems Corporation

Opinion

We are independent of the Group 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 reports 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 2024 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.

Revenue recognition

The Group recognized NT$738,560 thousand as net sales for the year ended December 31, 2024. Sales of products is the main operating activity of the Group. Its sale regions include not only Taiwan but also Asia and other regions. Trade terms of sales of products under each sale order may be different. It is necessary for the Group to judge and determine the performance obligations and the timing of its satisfaction under each sale order. As a result, we determined the matter to be a key audit matter.

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. These associates and joint ventures under equity method amounted to NT$0 thousand and NT$35,609 thousand, representing 0% and 0.2% of consolidated total assets as of December 31, 2024 and 2023, respectively. The related shares of losses from the associates and joint ventures under the equity method amounted to NT$1,567 thousand and NT$53,410 thousand, representing (0.3)% and (9)% of the consolidated net income before tax for the years ended December 31, 2024 and 2023, 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 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.

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 the override of internal control.
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 Group.
Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.
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 Group 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 Group and its subsidiaries to cease to continue as a going concern.
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.
Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group 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.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of 2024 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.

Others

We have audited and expressed an unqualified opinion on the parent company only financial statements of Silicon Integrated Systems Corporation as of and for the years ended December 31, 2024 and 2023.
