Independent Auditor's Report

No. 25611140CA

To the Board of Directors of Plotech Co., Ltd.

Opinion

We have audited the consolidated balance sheet of Plotech Co., Ltd. and its subsidiaries as of December 31, 2025, and the related consolidated statements of comprehensive income, changes in equity, and cash flows for the year then ended, including the notes to the consolidated financial statements.

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of Plotech Co., Ltd. and its subsidiaries as of December 31, 2025, and their financial performance and cash flows for the year then ended, in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Financial Reporting Standards (IFRS) as endorsed and issued by the Financial Supervisory Commission.

Basis for Opinion

We conducted our audit in accordance with the Regulations Governing Auditing and Attestation of Financial Statements by Certified Public Accountants and auditing standards generally accepted in Taiwan. We are independent of Plotech Co., Ltd. and its subsidiaries in accordance with the Code of Professional Ethics for Certified Public Accountants in Taiwan, 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

The consolidated financial statements indicate that Plotech Co., Ltd. and its subsidiaries incurred a consolidated net loss of NT$527,167 thousand for the year ended December 31, 2025, and that current liabilities exceeded current assets by NT$2,201,657 thousand. The accumulated deficit amounted to NT$1,121,086 thousand as of December 31, 2025. Management's plans to improve operations and financial position are described in Note 12(1). 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 consolidated financial statements of the current period. We do not provide a separate opinion on these matters.

Impairment Assessment of Property, Plant and Equipment
Refer to Notes 4(9), 5, and 6(7).
Due to the capital-intensive nature of the industry and uncertainties in estimating recoverable amounts based on discounted future cash flows, we considered the impairment assessment of property, plant and equipment as a key audit matter.
Existence of Sales Revenue
Refer to Notes 4(11) and 6(19).
Given that sales to the top ten customers represent a significant proportion of total revenue, and considering the competitive industry environment, we identified the existence of sales revenue as a key audit matter.

Other Matters

The consolidated financial statements of Plotech Co., Ltd. and its subsidiaries for the year ended December 31, 2024 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 the preparation and fair presentation of the consolidated financial statements in accordance with IFRS and 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 financial statements that are free from material misstatement, whether due to fraud or error.

Those charged with governance are responsible for overseeing the financial reporting process.

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 auditor’s 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 auditing standards will always detect a material misstatement.

1. Company History

Plotech Co., Ltd. (the “Company”) was incorporated on May 20, 1990. Plotech Co., Ltd. and its subsidiaries’ (the “Group”) principal business activities include the manufacturing, processing, and sale of printed circuit boards, electronic components, and related products, as well as PCB and film design services. The Company’s shares have been traded on the Taipei Exchange since September 2000 and on the Taiwan Stock Exchange since October 2003.

2. Date and Procedure of Financial Report Approval

The Consolidated 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 Group’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 Group 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

(1) Statement of Compliance

The consolidated financial statements have been prepared in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Financial Reporting Standards (IFRSs), International Accounting Standards (IASs), interpretations, and related guidance endorsed and issued by the Financial Supervisory Commission.

(2) Basis of Preparation

Except for certain financial instruments measured at fair value and net defined benefit liabilities recognized at the present value of defined benefit obligations less the fair value of plan assets, the consolidated financial statements have been prepared on a historical cost basis. Preparation of financial statements in conformity with IFRSs requires management to make judgments, estimates, and assumptions. Areas involving significant judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements, are disclosed in Note 5.

(3) Basis of Consolidation

The consolidated financial statements include the accounts of the Company and entities controlled by the Company (subsidiaries).

Subsidiaries’ financial statements are adjusted to align accounting policies with those of the Group. Intercompany transactions, balances, income, and expenses are eliminated in full.

Changes in ownership interests that do not result in loss of control are accounted for as equity transactions. When control is lost, the difference between consideration received plus fair value of retained interest and the carrying amount of assets, liabilities, and non-controlling interests is recognized in profit or loss.

List of Subsidiaries:

Note: In Q1 2025, Kunshan did not subscribe proportionally to Nantong’s capital increase, reducing ownership to 96.08%.

(4) Classification of Assets and Liabilities

Current assets: expected to be realized within the normal operating cycle, held for trading, realizable within 12 months, or cash equivalents not restricted for at least 12 months.
Current liabilities: expected to be settled within the operating cycle, held for trading, due within 12 months, or without substantive rights to defer settlement beyond 12 months.

(5) Foreign Currency Transactions

Foreign currency transactions are translated into functional currency at exchange rates prevailing at transaction dates. Monetary items are retranslated at closing rates; exchange differences are recognized in profit or loss unless related to items measured at fair value through OCI.

(6) Inventories

Inventories are measured at the lower of cost or net realizable value. Cost is determined using the weighted-average method. Finished goods and work-in-progress include raw materials, direct labor, and manufacturing overhead.

(7) Property, Plant and Equipment

PPE is stated at cost less accumulated depreciation and impairment losses. Depreciation is provided on a straight-line basis over estimated useful lives:

Buildings: 4–56 years
Machinery: 4–10 years
Pollution control equipment: 4–10 years
Transportation equipment: 5–10 years
Office equipment: 4–6 years
Other equipment: 4–10 years

(8) Intangible Assets

Finite-life intangible assets are measured at cost less accumulated amortization and impairment losses, amortized on a straight-line basis.

(9) Impairment of Non-financial Assets

Assets are tested for impairment when indicators exist. Recoverable amount is the higher of fair value less costs of disposal and value in use.

(10) Financial Instruments

Financial assets are classified as measured at amortized cost or at fair value through profit or loss. Expected credit losses are recognized for receivables and other financial assets.

(11) Revenue Recognition

Revenue from sales of printed circuit boards is recognized when control of goods transfers to customers, typically upon delivery.

(12) Leases

As lessor: leases transferring substantially all risks and rewards are classified as finance leases; others as operating leases.
As lessee: right-of-use assets and lease liabilities are recognized at commencement, except for short-term and low-value leases.

(13) Employee Benefits

Short-term benefits: recognized as expenses when services are rendered.

Defined contribution plans: contributions recognized as expenses.
Defined benefit plans: obligations measured at present value, actuarial gains/losses recognized in OCI.

(14) Income Taxes

Income tax expense comprises current and deferred tax. Deferred tax assets are recognized when it is probable that taxable profit will be available.

(15) Government Grants

Grants are recognized when reasonable assurance exists that conditions will be met and the grants will be received.

5. Significant Accounting Judgments, Estimates, and Assumptions

Inventory Valuation: Estimation of net realizable value considering obsolescence and market demand.
Impairment of Financial Assets: Based on expected credit losses using historical data and forward-looking information.
Impairment of Non-financial Assets: Requires judgment in estimating cash flows, useful lives, and discount rates.
Deferred Tax Assets: Recognition depends on future taxable profits and assumptions about growth, profitability, and tax planning.

Key points:

Under IFRS 9, credit risk is considered to have significantly increased if payments are more than 30 days past due; default is deemed to have occurred if payments are more than 90 days past due.
The Group applies the simplified approach, using a provision matrix based on customer ratings to estimate expected credit losses.
Financial assets deemed unrecoverable after collection procedures are written off, though legal actions continue to preserve creditor rights.
Forward-looking information is incorporated into historical and current loss rates to estimate allowances.

As of December 31, 2025 and 2024, the consolidated company had endorsed and transferred notes receivable to third parties to settle accounts payable to suppliers in the amounts of NT$1,949 thousand and NT$0 thousand, respectively. These notes had not yet matured and had not been derecognized. If the drawer or acceptor refuses payment at maturity, the consolidated company, as endorser, bears the obligation to repay.
As of December 31, 2025 and 2024, the consolidated company had discounted notes receivable in the amounts of NT$4,642 thousand and NT$23,626 thousand, respectively. These notes had not yet matured and did not meet derecognition criteria. If the drawer refuses payment at maturity, the consolidated company bears the repayment obligation; however, under normal circumstances, the company does not expect the acceptor to refuse payment.
The consolidated company assessed that certain notes receivable discounted with banks or endorsed and transferred to third parties met the derecognition criteria for financial assets. Nevertheless, if the drawer or acceptor refuses payment at maturity, the consolidated company bears the repayment obligation. The credit ratings of the aforementioned drawers or acceptors are considered very high.

Under the Company Act, capital surplus arising from share premiums or donations may be used to offset losses or, when no accumulated losses exist, distributed as stock or cash dividends to shareholders in proportion to their holdings. According to the Securities and Exchange Act, such distributions are limited to 10% of paid-in capital per year. Capital surplus cannot be used to cover capital losses unless legal reserves are insufficient.

(18) Retained Earnings

Per the Articles of Incorporation, annual profits (if any) are allocated in the following order: taxes, offsetting accumulated losses, 10% legal reserve, special reserve as required, then distribution of remaining earnings (including prior years' undistributed earnings) subject to shareholder approval.
Dividend policy considers growth stage, future funding needs, and shareholder expectations. At least 10% of distributable earnings must be allocated to dividends, with cash dividends ranging from 10%-100% and stock dividends from 0%-90%.
Legal reserve may only be used to offset losses or distributed as stock/cash dividends, limited to the portion exceeding 25% of paid-in capital.
Special reserve requirements:
If equity items show debit balances, special reserve must be appropriated before dividends.
IFRS adoption in 2012 required special reserve of NT$157,505 thousand, which remains unchanged as of Dec. 31, 2025 and 2024.

(1) Operating and Financial Improvement Plans

For the year ended December 31, 2025 (Year 114), the group reported a net loss attributable to owners of the parent of $527,167k, and current liabilities exceeded current assets by $2,201,657k. The group intends to adopt the following measures to improve future operations and financial position:

1. Operational improvement plans:

Plotech Nantong’s major customer launched new mobile phone products, leading to increasing orders; Taiwan operations actively secured high-margin semiconductor test board orders. Revenue and profit are expected to grow significantly in 2026 (Year 115).
The group is actively negotiating with customers to collect or discount accounts receivable to strengthen working capital. Factoring agreements with major customers in Kunshan and Nantong are under discussion to accelerate cash inflows.
Product mix adjustments to offset rising production and procurement costs:
Taiwan operations will reduce low-margin products and focus on higher-margin orders.
Nantong operations are renegotiating order prices and plan another price increase in Q1 2026 to improve profitability.

2. Financial improvement plans:

Strengthen credit control for individual customers to avoid bad debts and expected credit losses.
Prudently evaluate capital management to balance effective use of funds and cost control.
As of Dec 31, 2025, the group renewed borrowings from financial institutions totaling $2,459,819k.
The group obtained financial support commitments from major shareholders to ensure continued operations and debt repayment.
Subsidiaries Kunshan and Nantong signed installment repayment agreements with suppliers; as of the report date, signed agreements amounted to RMB 32,063k, with RMB 26,897k under negotiation.
Nantong plans to increase credit lines and finance leases to supplement working capital needs.

(2) Capital Management

The group plans future working capital requirements considering industry characteristics, company development, and external environment changes, aiming to ensure sustainable operations, shareholder returns, and stakeholder interests. The group adopts prudent risk management strategies. To maintain or adjust capital structure, the group may adjust dividend payments, issue new shares, or repurchase shares.

2. Risk management policies:

The group is exposed to market risk (foreign exchange, interest rate, price), credit risk, and liquidity risk.
Risk management is executed by the finance department under board-approved policies, including hedging strategies, credit controls, and investment guidelines.

Nature and extent of major financial risks:
Foreign exchange risk: Exposure mainly to USD and RMB due to cross-border operations. Hedging via forward contracts is used to mitigate inventory purchase cost volatility.
Price risk: Exposure to equity instruments measured at FVPL. A 1% change in equity prices would affect net profit by $204k (2025) and $277k (2024).
Interest rate risk: Floating-rate borrowings in USD and RMB expose the group to cash flow risk. A 1% increase in USD rates would reduce net profit by $884k (2025). A 1% increase in RMB rates would reduce net profit by $22,562k (2025) and $12,134k (2024).
Credit risk: Managed at group level, with strict counterparty requirements and credit analysis for new customers.
Liquidity risk: Cash flow forecasts are consolidated by the finance department. As of Dec 31, 2025, unused credit facilities totaled $299,269k.
