• 1.The Chair and the President are requested to provide an overview of the Company’s operations.

The Chair and the designated personnel responded as follows:

Chair’s Response:

The core business of the Company remains on a growth trajectory; however, due to macroeconomic factors, the financial performance did not meet expectations. The

Company’s management team remains committed to its operations. In the face of various challenges, we continue to prioritize shareholders’ interests, with the goal of maximizing

• 13 -

shareholder value.

President’s Response:

  - We sincerely thank our shareholders for their continued support. We deeply regret that the Company’s consolidated operating results for 2024 did not meet expectations. The loss was mainly due to underperformance in investments and non-operating items. The Company has been gradually divesting from non-core investments to focus on its core business. The core operations remain stable and continue to grow. Although there have been some recent disturbances due to global market conditions, the Company’s core business remains healthy.

• 2.The recent decline in the Company’s share price has caused significant losses for shareholders. It is recommended that the Company adopt a strategy of retaining high-performing assets and personnel while phasing out underperforming ones. In addition, although the Chairperson and the President have not sold any shares personally, there have been cases of senior executives selling a large volume of shares, which may give the public an impression of a lack of confidence in the Company. This issue requires the Company’s attention. Furthermore, the losses incurred by the investee company, Yo-Juang Investment Corporation, have placed a burden on the Company and must be carefully addressed.

• Chair’s Response: Thank you for your continued support and valuable feedback.

• VII. End of meeting: At 09:45 a.m. on the same day, the chairperson announced the end of the meeting.

• (The meeting minutes recorded the essentials and results of the meeting in accordance with the provisions of Paragraph 4, Article 183 of the Company Act. The actual content, procedures and shareholder speeches during the meeting are subject to the audio and video recordings of the meeting.)

Taiwan Mask Corporation 2024 Business Report

To begin with, I would like to express my appreciation to all shareholders for their support. The global economic growth in 2024 is affected by international situations, geopolitical conflicts, and uncertainties, as well as inflation, which affects the fluctuation of energy and raw material prices, making the recovery of the consumer market uncertain. However, the continued development of AI, high-performance computing and cloud services has been driving the growth of related supply chains such as logic chips, memory and advanced packaging technologies. The global semiconductor market is expected to continue to grow by more than double digits in 2025. Overall, the difference between semiconductor process technologies and applications will result in a different end demand. In this regard, TMC has a stable deployment strategy to plan for new capacity and new technologies in response to overall needs in a timely and appropriate manner, so as to grow together with strategic partners. At the same time, we will continue to strengthen operational management efficiency, deepen customer relationship management and services, and grow together with strategic customers.

Faced with a global semiconductor market downturn, TMC, through expanding its photomask foundry services for strategic partners and the concerted efforts of its management team and all employees, still maintained steady operational growth in 2024. The annual individual net revenue reached NT$4.26 billion, a 6.9% increase compared to the previous year. However, impacted by delays in the technology and product transformation of its subsidiaries, Taiwan Mask Corporation recognized operating losses from its subsidiaries, resulting in a net loss after tax of NT$473 million for the current period. In response to this, the Group has actively reorganized its resources and established effective allocation strategies to strengthen the photomask core business, continuously improve the quality and delivery time of 65/55nm photomask products, deepen partnerships with key customers, proactively expand the 40nm photomask customer base, and deploy 12-inch high-end and 28nm photomask production capacity.

Looking forward to 2025, in response to market growth, TMC will continue to:

1. Strengthen the core business of the Company, continue to work closely with strategic customers, and deepen customer cooperation. In line with the technological advancements of strategic customers, the Company has completed the mass production of 40nm photomasks and has successively obtained

2. customer certifications for 28nm photomasks. Furthermore, based on long-term

3. 15 -

market demand, the Company continues to deploy high-end photomask production capacity, aiming to shorten customer certification and mass production timelines, thereby fostering sustained growth with strategic customers.

1. On the operational front, the Company continues to establish and utilize AI-powered analysis and classification models to build a traceability mechanism for rapid and effective production improvements, thereby enhancing yield rates, shortening delivery times, and reasonably controlling costs, ultimately increasing capacity utilization and optimizing order intake to improve company profitability.

2. Continuous implementation of sustainable development:

TMC adheres to the business philosophy of “Respect for the sky, love for people, and protect the planet”. We pursue sustainable development through energy creation and conservation. By focusing on core business development, managing the Group’s total resources, aiming at innovation and sustainability, and working with strategic customers, suppliers, subsidiaries of the Group, and stakeholders to integrate resources, we will continue to implement sustainable development.

1. Integration of Group Synergies:

To enhance group synergies, the Company aims to establish a strategic mechanism and system characterized by speed, flexibility, and agility. This will allow the Company to adaptively adjust the allocation of group resources and the operational strategies of its investees in response to geopolitical and market uncertainties, as well as to expedite the transformation and support the successful operational turnaround of its subsidiaries.

Best wishes to all valued shareholders.

Based on our audits and the reports of the other independent 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 the consolidated financial statements of fiscal year 2024. 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 TMC Group’s consolidated financial statements in fiscal year 2024 are stated as follows:

• 19 -

Income recognition

Explanation

For the accounting policy on income recognition, please refer to Note 4 (29) of the financial report. For sales revenue, please refer to Note 6 (23); the operating income in fiscal year 2024 was NT$7,561,749 thousand.

The Group mainly produces and sells products such as masks and integrated circuits used in semiconductors, and has a large and diversified sales base. Trading conditions vary according to market conditions and customer needs. Considering that sales revenue is a major transaction that has a significant impact on the consolidated financial statements, we believe that the recognition of sales revenue is one of the most important matters to be considered in this year's audit.

How our audit addressed the matter

We have performed primary audit procedures for the above matter as follows:

• 1.Understand the type of major income and assess internal operations, review revenue recognition and accounting treatment.

• 2.Obtain the sales revenue statement, sample the sales transactions and verify the relevant documents to determine the appropriateness of the sales revenue.

• 3.Execute the cut-off test for the sales receipts transaction for a certain period of time before and after the closing date, and confirm that the account is correct at the time of entry.

Other matters–Parent company only financial reports

We have audited and expressed an unmodified opinion on the parent company only standalone financial statements of Taiwan Mask Corporation as of and for the years ended December 31, 2024 and 2023.

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 as endorsed and issued into effect 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.

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.

Independent Auditor’s 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 ROC AS 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 conducted in accordance with ROC AS, we exercise professional judgment and professional skepticism throughout the audit. We also conduct the following undertakings:

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 the override of internal control.

2. 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.

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

4. 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 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 report. However, future events or conditions may cause the Group to cease to continue as a going concern.

5. 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.

6. 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.

• 21 -

We communicated 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 for the current period.

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 the 2024 consolidated financial statements of the current period and are therefore deemed 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 auditor’s report because the adverse consequences of doing so would reasonable are expected to outweigh the public interest benefits of such communication.

Independent Auditors’ Report

(114) Tsai-Sheng-Bao-Zi No. 24005005

To Taiwan Mask Corporation:

Opinions

We have audited the accompanying parent-only balance sheets of Taiwan Mask Corporation as of December 31, 2024 and 2023, and the related statements of comprehensive income, of changes in equity and of cash flows for the years ended December 31, 2024 and 2023, and notes to the parent-only financial statements, including a summary of significant accounting policies.

In our opinion, based on our audits and the reports of the other independent auditors, as described in the Other matters section of our report, the parent-only financial statements present fairly, in all material respects, the standalone financial position of Taiwan Mask Corporation as of December 31, 2024 and 2023, and its financial performance and its cash flows for the years ending on December 31, 2024 and 2023, 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 Auditing and Attestation of Financial Statements by Certified Public Accountants and auditing standards generally accepted in Taiwan. Our responsibilities under those standards are further described in the Independent Auditor’s Responsibilities for the Audit of the Separate Financial Statements section of our report. We are independent of Taiwan Mask Corporation in accordance with the Code of Professional Ethics for Certified Public Accountants in the Republic of China (the “Code”), and we have fulfilled our other ethical responsibilities in accordance with the Code. Based on our audits and the reports of the other independent 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 the standalone financial statements of Taiwan Mask Corporation of fiscal year 2024. These matters were addressed in the context of our audit of the standalone financial statements as a whole and, in forming our opinion thereon, we do not provide a standalone opinion on these matters.

Key audit matters for the parent-only financial statements in fiscal year 2024 are stated as follows:

• 29 -

Income recognition

Explanation

For the accounting policy on income recognition, please refer to Note 4 (27) of the financial report. For sales revenue please refer to Note 6 (21); the operating income in fiscal year 2024 is NT$4,260,484 thousand.

Taiwan Mask Corporation mainly produces and sells products such as masks and integrated circuits used in semiconductors, and has a large and diversified sales base. Trading conditions vary according to market conditions and customer needs. Considering that sales revenue is a major transaction that has a significant impact on the standalone financial statements, we believe that the recognition of sales revenue is one of the most important matters to be considered in this year's audit.

How our audit addressed the matter

We have performed primary audit procedures for the above matter as follows:

• 1.Understand the type of major income and assess internal operations, review revenue recognition and accounting treatment.

• 2.Obtain the sales revenue statement, sample the sales transactions and verify the relevant documents to determine the appropriateness of the sales revenue.

• 3.Execute the cut-off test for the sales receipts transaction for a certain period of time before and after the closing date, and confirm that the account is correct at the time of entry.

Responsibilities of management and those charged with governance for the parent only financial statements

Management is responsible for the preparation and fair presentation of the standalone 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 as endorsed by the Financial Supervisory Commission, and for such internal control as management determines is necessary to enable the preparation of standalone financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the parent only financial statements, management is responsible for assessing Taiwan Mask Corporation’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 Taiwan Mask Corporation 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 Taiwan Mask Corporation's financial reporting process.

• 30 -

Independent auditor’s responsibilities for the audit of the standalone financial statements

Our objectives are to obtain reasonable assurance about whether the parent 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 ROC AS 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 standalone financial statements.

As part of an audit conducted in accordance with ROC AS, we exercise professional judgment and professional skepticism throughout the audit. We also conduct the following undertakings:

• 1.Identify and assess the risks of material misstatement of the parent 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.

• 2.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 Taiwan Mask Corporation’s internal control.

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

• 4.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 Taiwan Mask Corporation’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our report to the related disclosures in the parent 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 report. However, future events or conditions may cause Taiwan Mask Corporation to cease to continue as a going concern.

• 5.Evaluate the overall presentation, structure and content of the standalone financial statements, including the disclosures, and whether the standalone financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

• 6.Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within Taiwan Mask Corporation to express an opinion on the parent only financial statements. We are responsible for the direction, supervision and performance of the audit. We remain solely responsible for our audit opinion.

• 31 -

We communicated 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 for the current period.

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 the parent-only financial statements for the year ended December 31, 2024, 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 auditor’s report because the adverse consequences of doing so would reasonable are expected to outweigh the public interest benefits of such communication.
