Independent Auditors’ Report and 2025 Parent Company Only Financial Statements

INDEPENDENT AUDITORS’ REPORT TRANSLATED FROM CHINESE

To the Board of Directors and Shareholders of Taiwan Surface Mounting Technology Corp.

Opinion

We have audited the accompanying parent company only balance sheets of Taiwan Surface Mounting Technology Corp. (the “Company”) as at December 31, 2025 and 2024, and the related parent company only statements of comprehensive income, of changes in equity and of cash flows for the years then ended, and notes to the parent company only financial statements, including a summary of material accounting policies.

In our opinion, the accompanying parent company only financial statements present fairly, in all material respects, the parent company only financial position of the Company as at December 31, 2025 and 2024, and its parent company only financial performance and its parent company only cash flows for the years then ended in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers.

Basis for opinion

We conducted our audits in accordance with the Regulations Governing Financial Statement Audit and Attestation Engagements of Certified Public Accountants and 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 Accountants of the Republic of China, and we have fulfilled our other ethical responsibilities in accordance with these requirements. 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 judgement, were of most significance in our audit of the Company’s 2025 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, we do not provide a separate opinion on these matters.

Key audit matters for the Company’s 2025 parent company only financial statements are stated as follows:

Existence of revenues of the newly top 10 significant customers

Description

Please refer to Note 4(25) for accounting policy on recognition of revenue and Note 6(18) for details of sales revenue.

Considering that the customers’ demand has changed, the Company adjusted its product type. There were changes in sales customers resulting from changes in market demand and introduction of new products. As the sales revenue from the newly top 10 significant customers are significant to parent company only financial statements, we consider the existence of sales revenue from the newly top 10 significant customers a key audit matter.

How our audit addressed the matter:

We performed the following audit procedures on the above key audit matter:

A. Obtained the evaluation data of the newly top 10 significant customers, completed an understanding of the Company’s transaction counterparties, and assessed new transaction counterparties based on the internal controls.

B. Obtained detailed listing of sales revenue, performed detailed tests for the newly top significant customers and verified relevant evidences including customer sales invoices, purchase orders and delivery documents.

C. Inspected contents and relevant evidences of the newly top 10 significant customers in relation to sales returns and discounts occurring subsequent to the reporting period and assessed the reasonableness of respective sales revenue recognised.

Valuation of allowance for inventory valuation losses

Description

For a description of the accounting policy on inventory valuation, please refer to Note 4(11); for accounting estimates and assumption uncertainty in relation to inventory valuation, please refer to Note 5(2); and for information on the allowance for inventory valuation losses, please refer to Note 6(6).

As of December 31, 2025, the Company’s inventories and allowance for inventory valuation losses amounted to NT$951,179 thousand and NT$154,081 thousand, respectively. The Company is primarily engaged in designing, processing, manufacturing and trading of TFT-LCD panels, general electronic information products and PCB surface mount packaging. In addition, the Company also manufactured made-to-order products. Taking into consideration that those products have short life spans and are affected by the fluctuating market price of TFT-LCD panels, there is a higher risk of inventory losses due to market value decline or obsolescence. Inventories are stated at the lower of cost and net realisable value. The net realisable value which was used in the individual identification and valuation of allowance for inventory valuation losses, involved subjective judgment and uncertainty of estimation. As the Company’s inventory and allowance for inventory valuation losses are significant to financial statements, as well as being significant to the Company’s subsidiaries, which are recognised as investments accounted for using equity method, we identified inventory valuation loss as a key audit matter.

How our audit addressed the matter

We performed the following audit procedures on the above key audit matter:

A. Discussed with management to determine whether the provision policy and procedure of allowance for inventory valuation loss is consistently applied for the comparative periods in the financial statements.

-13-

B. Understood the Company’s warehousing control procedures. Reviewed the annual physical inventory count plan and observed the annual inventory count in order to assess the effectiveness of the classification of obsolete inventory and internal control over obsolete inventory.

C. Verified whether the inventory aging report that were used to assess obsolete and slow-moving inventories was correct, including changes in inventories being classified according to inventory aging.

D. Checked the appropriateness of the estimation basis adopted by the Company for the evaluation of net realisable value, verified accuracy of inventory selling and purchase prices and recalculated and evaluated the reasonableness of allowance for inventory valuation losses.

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 Regulations Governing the Preparation of Financial Reports by Securities Issuers, and for such internal control as management determines is necessary to enable the preparation of 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 Company’s ability to continue as a going concern, 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.

-14-

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

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 Company’s internal control.
Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.

-15-

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 Company’s ability to continue as a going concern. 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 disclosures, 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 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.

-16-

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the parent company only financial statements of the current period 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 and 2025 Consolidated Financial Statement

INDEPENDENT AUDITORS’ REPORT TRANSLATED FROM CHINESE
To the Board of Directors and Shareholders of Taiwan Surface Mounting Technology Corp.

Opinion

We have audited the accompanying consolidated balance sheets of Taiwan Surface Mounting Technology Corp. and subsidiaries (the “Group”) as at December 31, 2025 and 2024, and the related consolidated statements of comprehensive income, of changes in equity and of cash flows for the years then ended, and notes to the consolidated financial statements, including a summary of material accounting policies.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Group as at December 31, 2025 and 2024, and its consolidated financial performance and its consolidated cash flows for the years then ended in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and the International Financial Reporting Standards, International Accounting Standards, IFRIC Interpretations, and SIC Interpretations that came into effect as endorsed by the Financial Supervisory Commission.

Basis for opinion

We conducted our audits in accordance with the Regulations Governing Financial Statement Audit and Attestation Engagements of Certified Public Accountants and 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 Group in accordance with the Norm of Professional Ethics for Certified Public Accountants of the Republic of China, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

-25-

Key audit matters

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the Group’s 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, we do not provide a separate opinion on these matters.

Key audit matters for the Group’s 2025 consolidated financial statements are stated as follows:

Existence of revenues of the newly top 10 significant customers

Description

Please refer to Note 4(26) for accounting policy on recognition of revenue and Note 6(18) for details of sales revenue.

Considering that the customers’ demand has changed, the Group adjusted its product type. There were changes in sales customers resulting from changes in market demand and introduction of new products. As the sales revenue from the newly top 10 significant customers are significant to the consolidated financial statements, we consider the existence of sales revenue from the newly top 10 significant customers a key audit matter.

How our audit addressed the matter:

We performed the following audit procedures on the above key audit matter:

A. Obtained the evaluation data of the newly top 10 significant customers, completed an understanding of the Group’s transaction counterparties, and assessed new transaction counterparties based on the internal controls.

B. Obtained detailed listing of sales revenue, performed detailed tests for the newly top 10 significant customers and verified relevant evidences including customer sales invoices, purchase orders and delivery documents.

Valuation of allowance for inventory valuation losses

Description

For a description of the accounting policy on inventory valuation, please refer to Note 4(13); for accounting estimates and assumption uncertainty in relation to inventory valuation, please refer to Note 5(2); and for information on the allowance for inventory valuation losses, please refer to Note 6(7).

As of December 31, 2025, the Group’s inventories and allowance for inventory valuation losses amounted to NT$4,021,106 thousand and NT$418,907 thousand, respectively. The Group is primarily engaged in designing, processing, manufacturing, and trading of TFT-LCD panels, general electronic information products and PCB surface mount packaging. In addition, the Group also manufactured made-to-order products. Taking into consideration that those products have short life spans and are affected by the fluctuating market price of TFT-LCD panels, there is a higher risk of inventory losses due to market value decline or obsolescence. Inventories are stated at the lower of cost and net realisable value. The net realisable value which was used in the individual identification and valuation of allowance for inventory valuation losses, involved subjective judgment and uncertainty of estimation. The Group’s inventory and allowance for inventory valuation losses are significant to the consolidated financial statements. Thus, we identified the valuation of allowance for inventory valuation loss as a key audit matter.

How our audit addressed the matter

We performed the following audit procedures on the above key audit matter:

-26-

B. Understood the Group’s warehousing control procedures. Reviewed the annual physical inventory count plan and observed the annual inventory count in order to assess the effectiveness of the classification of obsolete inventory and internal control over obsolete inventory.

D. Checked the appropriateness of the estimation basis adopted by the Group for the evaluation of net realisable value, verified accuracy of inventory selling and purchase prices and recalculated and evaluated the reasonableness of allowance for inventory valuation losses.

Other matter – Parent company only financial reports

We have audited and expressed an unmodified opinion on the parent company only financial statements of Taiwan Surface Mounting Technology Corp. as at and for the years ended December 31, 2025 and 2024.

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 Regulations Governing the Preparation of Financial Reports by Securities Issuers and the International Financial Reporting Standards, International Accounting Standards, IFRIC Interpretations, and SIC Interpretations that came into effect as endorsed by the Financial Supervisory Commission, 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.

-27-

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

Those charged with governance, including the audit committee, are responsible for overseeing the Group's financial reporting process.

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:

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.

-28-

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 Group’s internal control.
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 Group’s ability to continue as a going concern. 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 to cease to continue as a going concern.
Evaluate the overall presentation, structure, and content of the consolidated financial statements, including the disclosures, 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.

-29-

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the consolidated financial statements of the current period 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.
