Independent Auditor’s Report
No. 25611140A
To: Board of Directors, Plotech Co., Ltd.

Audit Opinion

We have audited the individual balance sheet of Plotech Co., Ltd. as of December 31, 2025, and the individual statements of comprehensive income, changes in equity, and cash flows for the year ended December 31, 2025, together with the notes to the individual financial statements (including a summary of significant accounting policies).

In our opinion, the accompanying individual financial statements present fairly, in all material respects, the financial position of Plotech Co., Ltd. as of December 31, 2025, and its financial performance and cash flows for the year then ended, in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers.

Basis for Opinion

We conducted our audit in accordance with the Regulations Governing Auditing and Attestation of Financial Reports by Certified Public Accountants and auditing standards. Our responsibilities under those standards are further described in the section “Auditor’s Responsibilities for the Audit of the Individual Financial Statements.” We are independent of Plotech Co., Ltd. in accordance with the Code 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.

Emphasis of Matter

Due to accumulated losses, as of December 31, 2025, Plotech Co., Ltd. had an accumulated deficit of NT$1,121,086 thousand, which has reached half of its paid-in capital. Please refer to Note 12(1) for the company’s operational and financial improvement plans. Our opinion is not modified in respect of this matter.

Key Audit Matters

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

1. Impairment assessment of property, plant, and equipment under the equity method

• The accounting policy for non-financial asset impairment is disclosed in Note 4(9).
• The estimation uncertainty is disclosed in Note 5.
• Subsidiaries operate in highly capital-intensive industries facing economic and competitive pressures. The impairment assessment involves forecasting and discounting future cash flows, which inherently carries significant uncertainty.
• Audit procedures performed included:
• Understanding impairment policies and procedures, evaluating management’s identification of cash-generating units.
• Reviewing independent valuation reports, assessing assumptions, and evaluating the qualifications and independence of the valuers.

2. Existence of sales revenue

• The accounting policy for revenue recognition is disclosed in Note 4(11).
• Sales revenue details are disclosed in Note 6(15).
• The company manufactures and sells printed circuit boards, with major customers being well-known enterprises. The top ten customers account for a significant proportion of revenue.
• Audit procedures performed included:
• Reviewing credit approval processes for major customers and evaluating new top-ten customers.
• Obtaining and testing detailed sales records and supporting documents.
• Confirming subsequent collections and accounts receivable balances with top-ten customers.

Other Matter

The 2024 individual financial statements of Plotech Co., Ltd. were audited by other auditors, who expressed an unmodified opinion on March 31, 2025.

Responsibilities of Management and Those Charged with Governance

Management is responsible for preparing financial statements in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers, and for maintaining necessary internal controls to ensure the financial statements are free from material misstatement, whether due to fraud or error.

Management is also responsible for assessing the company’s ability to continue as a going concern, disclosing matters related to going concern, and using the going concern basis of accounting unless liquidation or cessation of operations is intended or unavoidable.

Those charged with governance (including the Audit Committee) are responsible for overseeing the financial reporting process.

Auditor’s Responsibilities

Our objectives are to obtain reasonable assurance about whether the financial statements are free from material misstatement, and to issue an audit report. Reasonable assurance is a high level of assurance but not a guarantee that an audit conducted in accordance with auditing standards will always detect material misstatements.

We exercise professional judgment and maintain professional skepticism throughout the audit. Our responsibilities include:

1. Identifying and assessing risks of material misstatement due to fraud or error, designing and performing audit procedures responsive to those risks, and obtaining sufficient appropriate evidence.
2. Understanding internal control relevant to the audit to design appropriate procedures, but not to express an opinion on the effectiveness of internal control.
3. Evaluating the appropriateness of accounting policies and reasonableness of estimates and disclosures.
4. Concluding on the appropriateness of management’s use of the going concern basis of accounting.
5. Evaluating the overall presentation, structure, and content of the financial statements.
6. Obtaining sufficient evidence regarding financial information of components to express an opinion on the financial statements as a whole.
7. We communicate with those charged with governance regarding the planned scope and timing of the audit, significant findings, and independence matters. From these communications, we determine key audit matters to be included in our report.

The individual financial statements were approved by the Board of Directors on March 30, 2026.

3. Application of Newly Issued and Revised Standards

(1) Standards adopted in 2025 The Company applied the amendments to IAS 21 "Lack of Exchangeability" effective January 1, 2025. The adoption had no material impact on the Company's financial position or performance.

(2) Standards effective in 2026 but not yet adopted The FSC has endorsed amendments to IFRS 9 and IFRS 7 (classification and measurement of financial instruments; contracts involving nature-dependent electricity), IFRS 17 "Insurance Contracts" and related amendments, and the Annual Improvements (Cycle 11), effective January 1, 2026. The Company assessed that these will not have a material impact.

(3) Standards issued by IASB but not yet endorsed by the FSC These include amendments to IFRS 10 and IAS 28 (sale or contribution of assets between investor and associates/joint ventures), IFRS 18 "Presentation and Disclosure in Financial Statements" (effective January 1, 2027, with early adoption permitted once endorsed), IFRS 19 "Subsidiaries without Public Accountability: Disclosures," and amendments to IAS 21 (translation into hyperinflationary currency). IFRS 18 replaces IAS 1, updates the structure of the statement of profit or loss, introduces disclosures of management performance measures, and strengthens aggregation/disaggregation principles.

4. Summary of Significant Accounting Policies

• Statement of Compliance: Prepared in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers.
• Basis of Preparation: Historical cost basis, except for certain financial instruments measured at fair value and defined benefit obligations measured at present value less plan assets.
• Classification of Assets and Liabilities: Current vs. non-current based on expected realization/settlement within the operating cycle or 12 months.
• Foreign Currency: Transactions translated at exchange rates on transaction date; monetary items retranslated at closing rate; exchange differences recognized in profit or loss or OCI depending on measurement basis.
• Inventories: Measured at the lower of cost and net realizable value, using weighted-average method.
• Investments in Subsidiaries (Equity Method): Recognized at cost, adjusted for share of profit/loss and OCI. Goodwill recognized if acquisition cost exceeds fair value of net assets.
• Property, Plant, and Equipment: Recorded at cost, depreciated on a straight-line basis over useful lives.
• Intangible Assets: Recorded at cost, amortized on a straight-line basis over useful lives.
• Impairment of Non-Financial Assets: Assessed at each reporting date; impairment losses recognized when carrying amount exceeds recoverable amount.
• Financial Instruments:

• Financial liabilities measured at amortized cost unless designated at fair value.
• Revenue Recognition: Revenue recognized when control of goods transfers to customers, typically upon delivery.

Short-term benefits measured at undiscounted amounts.
Defined contribution plans expensed as incurred.
Defined benefit plans measured using projected unit credit method; actuarial gains/losses recognized in OCI.

• Income Taxes: Current and deferred taxes recognized; deferred tax assets recognized when probable future taxable income is available.

5. Major Sources of Estimation Uncertainty

• Inventory Valuation: Requires judgment to determine net realizable value, considering obsolescence and market demand.
• Impairment of Financial Assets: Based on assumptions about default rates and expected losses.
• Impairment of Non-Financial Assets: Relies on estimates of cash flows, useful lives, and industry conditions.
• Deferred Tax Assets: Recognition depends on management’s judgment about future taxable income, profitability, and tax planning strategies.

6. Explanation of Significant Accounting Items

3. Financial and Non-Financial Instruments Measured at Fair Value

The Company classifies assets and liabilities by nature, characteristics, risks, and fair value hierarchy.

As of December 31, 2025 (NT$ thousands):

• Equity securities at fair value through profit or loss:
