Review Report of Independent Auditors

To United Microelectronics Corporation

Introduction

We have reviewed the accompanying consolidated balance sheets of United Microelectronics Corporation and its subsidiaries (collectively, “the Company”) as of September 30, 2024 and 2023, the related consolidated statements of comprehensive income for the three-month and nine-month periods ended September 30, 2024 and 2023 and consolidated statements of changes in equity and cash flows for the nine-month periods ended September 30, 2024 and 2023, and notes to the consolidated financial statements, including the summary of material accounting policies (together “the consolidated financial statements”). ^^Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Accounting Standard 34, “Interim Financial Reporting” as endorsed and became effective by Financial Supervisory Commission of the Republic of China. Our responsibility is to express a conclusion on these consolidated financial statements based on our reviews.

Scope of Review

---

We conducted our reviews in accordance with the Standard on Review Engagements 2410, “Review of Financial Information Performed by the Independent Auditor of the Entity” of the Republic of China. A review of consolidated financial statements consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with the Standards on Auditing of the Republic of China and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

---

Based on our reviews and the review reports of other independent auditors (please refer to the Other Matter paragraph of our report), nothing has come to our attention that causes us to believe that the accompanying consolidated financial statements do not present fairly, in all material respects, the consolidated financial position of the Company as of September 30, 2024 and 2023, and its consolidated financial performance for the three-month and nine-month periods ended September 30, 2024 and 2023, and its consolidated cash flows for the nine-month periods ended September 30, 2024 and 2023, in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Accounting Standard 34, “Interim Financial Reporting” as endorsed and became effective by Financial Supervisory Commission of the Republic of China.

Other Matter – Making Reference to theReviews of Other Independent Auditors

We did not review the financial statement of certain associates and joint ventures accounted for under the equity method. Our review, insofar as it related to the investments accounted for under the equity method balances of NT$29,347 million and NT$28,015 million, which represented 5.11% and 5.12% of the total consolidated assets as of September 30, 2024 and 2023, respectively, the related shares of profit or loss from the associates and joint ventures in the amount of NT$358 million, NT$573 million, NT$1,378 million and NT$4,115 million, which represented 2.16%, 3.07%, 3.01% and 7.31% of the consolidated income from continuing operations before income tax for the three-month and nine-month periods ended September 30, 2024 and 2023, respectively, and the related shares of other comprehensive income (loss) from the associates and joint ventures in the amount of NT$(65) million, NT$226 million, NT$274 million and NT$208 million, which represented (0.53)%, 0.98%, 0.60% and 0.36% of the consolidated total comprehensive income (loss) for the three-month and nine-month periods ended September 30, 2024 and 2023, respectively, are based solely on the reports of other independent auditors.

UNITED MICROELECTRONICS CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For the Nine-Month Periods Ended September 30, 2024 and 2023

(Expressed in Thousands of New Taiwan Dollars unless Otherwise Specified)

1.	HISTORY AND ORGANIZATION

United Microelectronics Corporation (UMC) was incorporated in Republic of China (R.O.C.) in May 1980 and commenced operations in April 1982. UMC is a full service semiconductor wafer foundry, and provides a variety of services to satisfy customer needs. UMC’s ordinary shares were publicly listed on the Taiwan Stock Exchange (TWSE) in July 1985 and its American Depositary Shares (ADSs) were listed on the New York Stock Exchange (NYSE) in September 2000.

The address of its registered office and principal place of business is No. 3, Li-Hsin 2nd Road, Hsinchu Science Park, Hsinchu, Taiwan. The principal operating activities of UMC and its subsidiaries (collectively as “the Company”) are described in Notes 4(3) and 14.

2.	DATE AND PROCEDURES OF AUTHORIZATION OF FINANCIAL STATEMENTS FOR ISSUE

The consolidated financial statements of the Company were authorized for issue in accordance with a resolution of the Board of Directors’ meeting on October 30, 2024.

3.	NEWLY ISSUED OR REVISED STANDARDS AND INTERPRETATIONS
(1)	The Company applied International Financial Reporting Standards, International Accounting Standards, and<br>Interpretations issued, revised or amended which are endorsed by Financial Supervisory Commission (FSC) and become effective for annual<br>periods beginning on or after January 1, 2024. There are no newly adopted or revised standards and interpretations that have material<br>impact on the Company’s financial position and performance.
---	---
(2)	Standards issued by International Accounting Standards Board (IASB) which are endorsed by FSC, but not<br>yet adopted by the Company are listed below:
---	---
New, Revised or Amended Standards and Interpretations	Effective Date issued by IASB
---	---
Amendments to IAS 21 “The Effects of Changes in Foreign Exchange Rates” - Lack of Exchangeability	January 1, 2025

---

Amendments to IAS 21 “The Effects of Changes in Foreign Exchange Rates” - Lack of Exchangeability

These amendments specify whether a currency is exchangeable into another currency and, when it is not, to determining the exchange rate to use and the disclosures to provide.

The Company is currently evaluating the potential impact of the aforementioned standards and interpretations listed above to the Company’s financial position and performance, and the related impact will be disclosed when the evaluation is completed.

(3)	Standards issued by IASB but not yet endorsed by FSC (the effective dates are to be determined by FSC)<br>are listed below:
New, Revised or Amended Standards and Interpretations	Effective Date issued by IASB
---	---
IFRS 10 “Consolidated Financial Statements” and IAS 28 “Investments in Associates and Joint Ventures” - Sale or Contribution of Assets between an Investor and its Associate or Joint Ventures	To be determined by IASB
IFRS 17 “Insurance Contracts”	January 1, 2023

IFRS 19 “Disclosure Initiative - Subsidiaries without Public Accountability: Disclosures”	January 1, 2027
Amendments to IFRS 9 “Financial Instruments” and IFRS 7 “Financial Instruments: Disclosures” - Amendments to the Classification and Measurement of Financial Instruments	January 1, 2026
Annual Improvements to IFRS Accounting Standards - Volume 11	January 1, 2026

The potential effects of adopting the standards or interpretations issued by IASB but not yet endorsed by FSC on the Company’s financial statements in future periods are summarized as below:

a.	Amendments to IFRS 10 “Consolidated Financial Statements” (IFRS 10) and IAS 28 “Investments<br>in Associates and Joint Ventures” (IAS 28) - Sale or Contribution of Assets between an Investor and its Associate or Joint Ventures

The amendments address the inconsistency between the requirements in IFRS 10 and IAS 28, in dealing with the loss of control of a subsidiary that is contributed to an associate or a joint venture. IAS 28 restricts gains and losses arising from contributions of non-monetary assets to an associate or a joint venture to the extent of the interest attributable to the other equity holders in the associate or joint ventures. IFRS 10 requires full profit or loss recognition on the loss of control of the subsidiary. IAS 28 was amended so that the gain or loss resulting from the sale or contribution of assets that constitute a business as defined in IFRS 3 “Business Combinations” (IFRS 3) between an investor and its associate or joint venture is recognized in full.

11

IFRS 10 was also amended so that the gain or loss resulting from the sale or contribution of a subsidiary that does not constitute a business as defined in IFRS 3 between an investor and its associate or joint venture is recognized only to the extent of the unrelated investors’ interests in the associate or joint venture.

b.	IFRS 17 “Insurance Contracts” (IFRS 17)

IFRS 17 provides a comprehensive model for insurance contracts, covering all relevant accounting aspects (including recognition, measurement, presentation and disclosure requirements). The core of IFRS 17 is the General (building block) Model, under this model, on initial recognition, an entity shall measure a group of insurance contracts at the total of the fulfilment cash flows and the contractual service margin. The carrying amount of a group of insurance contracts at the end of each reporting period shall be the sum of the liability for remaining coverage and the liability for incurred claims.

Other than the General Model, the standard also provides a specific adaptation for contracts with direct participation features (the Variable Fee Approach) and a simplified approach (Premium Allocation Approach) mainly for short-duration contracts.

IFRS 17 was issued in May 2017 and it was amended in 2020 and 2021. The amendments include deferral of the date of initial application of IFRS 17 by two years to annual beginning on or after January 1, 2023 (from the original effective date of January 1, 2021), provide additional transition reliefs, simplify some requirements to reduce the costs of applying IFRS 17 and revise some requirements to make the results easier to explain. IFRS 17 replaces an interim Standard - IFRS 4 Insurance Contracts - from annual reporting periods beginning on or after January 1, 2023.

c.	IFRS 18 “Presentation and Disclosure in Financial Statements” (IFRS 18)

IFRS 18 replaces IAS 1 “Presentation of Financial Statements”. The main changes in the new standard are as below:

i.	Improved comparability in the statement of profit or loss (income statement)

IFRS 18 requires entities to classify all income and expenses within their statement of profit or loss into one of five categories: operating; investing; financing; income taxes; and discontinued operations. The first three categories are new, to improve the structure of the income statement, and requires all entities to provide new defined subtotals, including operating profit or loss. The improved structure and new subtotals will give investors a consistent starting point for analyzing entities’ performance and make it easier to compare entities.

12
ii.	Enhanced transparency of management-defined performance measures
---	---

IFRS 18 requires entities to disclose explanations of those entity-specific measures that are related to the income statement, referred to as management-defined performance measures.

iii.	Useful grouping of information in the financial statements

IFRS 18 sets out enhanced guidance on how to organize information and whether to provide it in the primary financial statements or in the notes. The changes are expected to provide more detailed and useful information. IFRS 18 also requires entities to provide more transparency about operating expenses, helping investors to find and understand the information they need.

d.	Amendments to IFRS 9 “Financial Instruments” (IFRS 9) and IFRS 7 “Financial Instruments:<br>Disclosures” (IFRS 7) - Amendments to the Classification and Measurement of Financial Instruments

The amendments include:

i.	Clarify that a financial liability is derecognised on the settlement date and describe the accounting<br>treatment for settlement of financial liabilities using an electronic payment system before the settlement date.
ii.	Clarify how to assess the contractual cash flow characteristics of financial assets that include environmental,<br>social and governance (ESG)-linked features and other similar contingent features.
---	---
iii.	Clarify the treatment of non-recourse assets and contractually linked instruments.
---	---
iv.	Require additional disclosures in IFRS 7 for financial assets and liabilities with contractual terms that<br>reference a contingent event (including those that are ESG-linked), and equity instruments classified at fair value through other comprehensive<br>income.
---	---

The Company is currently evaluating the potential impact of the aforementioned standards and interpretations listed (a) - (d) to the Company’s financial position and performance, and the related impact will be disclosed when the evaluation is completed.

13
4.	SUMMARY OF MATERIAL ACCOUNTING POLICIES
---	---

---	---

The collection periods for third party domestic sales and third party overseas sales were month-end 30 - 60 days and net 30 - 60 days, respectively.

An impairment analysis is performed at each reporting date to measure expected credit losses (ECLs) of accounts receivable. For the receivables past due within 60 days, including not past due, the Company estimates an expected credit loss rate to calculate ECLs. For the nine-month periods ended September 30, 2024 and 2023, the expected credit loss rates were not greater than 0.2%. The rate is determined based on the Company’s historical credit loss experience and customer’s current financial condition, adjusted for forward-looking factors such as customer’s economic environment. For the receivables past due over 60 days, the Company applies the aforementioned rate and assesses individually whether to recognize additional expected credit losses by considering customer’s operating condition and debt-paying ability.

Note A: In August 2023, the board chairman of SIS changed and became the same person as the board chairman of UMC. After considering the comprehensive conditions, including ownership interest held and representation on Board of Directors of SIS, etc., the Company determines that it has significant influence over SIS and accounts for its investment in SIS as an associate. SIS was previously measured at fair value through other comprehensive income and reclassified as investments accounted for under the equity method. UMC’s share of the net fair value of SIS’s identifiable assets and liabilities was in excess of the fair value of the previously held investment in SIS at the acquisition date, and the difference was recognized as bargain purchase gain. Cumulative fair value change that was previously recognized in other comprehensive loss up to reclassification date was reclassified to retained earnings in the current period. SIS executed a capital reduction and refunded NT$499 million based on UMC’s stockholding percentage in July 2024. UMC’s stockholding percentage remains unchanged.

Note B: Beginning from June 2015, the Company accounts for its investment in FARADAY as an associate given the fact that UMC obtained the ability to exercise significant influence over FARADAY through representation on its Board of Directors. The Company participated in the capital increase of FARADAY in March 2024. Please refer to Note 7 for the relevant information.

Note C: Beginning from June 2020, the Company accounts for its investment in UNIMICRON as an associate given the fact that UMC obtained the ability to exercise significant influence over UNIMICRON through representation on its Board of Directors. On January 6, 2023, UNIMICRON issued new shares to merge with SUBTRON TECHNOLOGY CO., LTD. (SUBTRON) through share conversion. The share conversion ratio was 1 common share of SUBTRON to exchange 0.219 common shares of UNIMICRON. The 23 million shares of SUBTRON held by the Company were exchanged to 5 million common shares newly issued by UNIMICRON.

Note D: When the Company’s share of losses of an associate equals or exceeds its interest in that associate, the Company discontinues recognizing its share of further losses. Additional losses and liabilities are recognized only to the extent that the Company has incurred legal or constructive obligations or made payments on behalf of that associate.

b.	On July 7, 2021, UMC issued SGX-ST listed currency linked zero coupon exchangeable bonds. In accordance<br>with IFRS 9, the value of the exchange right, call option and put option (together referred to as Option) of the exchangeable bonds was<br>separated from the host and accounted for as “financial liabilities at fair value through profit or loss, current”. The effective<br>rate of the host bond was 3.49%. The terms and conditions of the bonds are as follows:
---	---
i.	Issue Amount: USD 400 million
---	---
ii.	Period: July 7, 2021 - July 7, 2026 (Maturity Date)
---	---
iii.	Redemption:
---	---
(i)	UMC may, at its option, redeem in whole or in part at the principal amount of the bonds with an interest<br>calculated at the rate of -0.625% per annum (the Early Redemption Amount) at any time after the third anniversary from the issue date<br>and prior to the Maturity Date, if the closing price of the common shares of NOVATEK MICROELECTRONICS CORPORATION (NOVATEK) on the TWSE,<br>converted into U.S. dollars at the prevailing exchange rate, for 20 out of 30 consecutive trading days prior to the publication of the<br>redemption notice is at least 130% of the quotient of the Early Redemption Amount multiplied by the then exchange price (converted into<br>U.S. dollars at the Fixed Exchange Rate), divided by the principal amount of the bonds. The Early Redemption Amount will be converted<br>into NTD based on the Fixed Exchange Rate (NTD 27.902=USD 1.00), and this fixed NTD amount will then be converted using the prevailing<br>exchange rate at the time of redemption for payment in USD.
---	---
33
---
(ii)	UMC may redeem the outstanding bonds in whole, but not in part, at the Early Redemption Amount, in the<br>event that over 90% of the bonds have been previously redeemed, repurchased and cancelled or exchanged.
---	---
(iii)	In the event of any change in ROC taxation resulting in increase of tax obligation or the necessity to<br>pay additional interest expense or increase of additional costs to UMC, UMC may redeem the outstanding bonds in whole, but not in part,<br>at the Early Redemption Amount. Bondholders may elect not to have their bonds redeemed but with no entitlement to any additional amounts<br>or reimbursement of additional taxes.
---	---
(iv)	All or any portion of the bonds will be redeemable at put price at the option of bondholders on July 7,<br>2024 at 98.14% of the principal amount.
---	---
(v)	In the event that the common shares of NOVATEK cease to be listed or are suspended from trading for a<br>period equal to or exceeding 30 consecutive trading days on the TWSE, each bondholder shall have the right to require UMC to redeem the<br>bonds, in whole but not in part, at the Early Redemption Amount.
---	---
(vi)	Upon the occurrence of a change of control (as defined in the indenture) of UMC, each bondholder shall<br>have the right to require UMC to redeem the bonds, in whole but not in part, at the Early Redemption Amount.
---	---
iv.	Terms of Exchange:
---	---
(i)	Underlying Securities: Common Shares of NOVATEK
---	---
(ii)	Exchange Period: The bonds are exchangeable at any time on or after October 8, 2021 and prior to June<br>27, 2026, into NOVATEK common shares.
---	---

If for any reason UMC does not have sufficient NOVATEK common shares to deliver upon the exchange of any bond, then, UMC will pay to the exchanging bondholder an amount in U.S. dollars equal to the product of the volume-weighted average closing price per NOVATEK common share on the TWSE for five consecutive trading days starting from and including the applicable exercise date (as defined in the indenture) (or such fewer number of trading days as are available within ten days starting from and including the applicable exercise date) each converted into USD at the prevailing rate on the day preceding the applicable trading day and the number of NOVATEK common shares that UMC is unable to deliver. Provided, however, that if the exercise date falls within 5 business days from the beginning of, and during, any closed period, the right of the converting holder of the bonds to vote with respect to the shares it receives will be subject to certain restrictions.

(iii)	Exchange Price and Adjustment: The exchange price was originally NT$731.25 per NOVATEK common share. The<br>exchange price will be subject to adjustments upon the occurrence of certain events set out in the indenture. The exchange price was NT$506.0<br>per NOVATEK common share on September 30, 2024.
34
---
v.	Redemption on the Maturity Date:
---	---

The bonds will be redeemed with 96.92% principal amount on the maturity date unless:

(i)	UMC shall have redeemed the bonds at the option of UMC, or the bonds shall have been redeemed at option<br>of the bondholder,
(ii)	The bondholders shall have exercised the exchange right before maturity, or
---	---
(iii)	The bonds shall have been redeemed or repurchased by UMC and cancelled.
---	---

On July 7, 2024, there were no bondholders that required UMC to redeem the outstanding exchangeable bonds.

As of September 30, 2024, December 31, 2023 and September 30, 2023, UMC has cumulatively repurchased and cancelled the outstanding principal amount of exchangeable bonds totaling USD 187.1 million, USD 187.1 million and USD 187.1 million, respectively with derecognition of the related derivative financial liabilities.

(15)	Post-Employment Benefits
---	---
a.	Defined contribution plan
---	---

The employee pension plan under the Labor Pension Act of R.O.C. is a defined contribution plan. Pursuant to the plan, UMC and its domestic subsidiaries make monthly contributions of 6% based on each individual employee’s salary or wage to employees’ pension accounts. Pension benefits for employees of the Singapore branch and subsidiaries overseas are provided in accordance with the local regulations. Total pension expenses of NT$501 million, NT$228 million, NT$1,482 million and NT$1,180 million were contributed by the Company for the three-month and nine-month periods ended September 30, 2024 and 2023, respectively.

40
b.	Defined benefit plan
---	---

The employee pension plan mandated by the Labor Standards Act of R.O.C. is a defined benefit plan. The pension benefits are disbursed based on the units of service years and average monthly salary prior to retirement according to the Labor Standards Act. Two units per year are awarded for the first 15 years of services while one unit per year is awarded after the completion of the 15th year and the total units will not exceed 45 units. The Company contributes an amount equivalent to 2% of the employees’ total salaries and wages on a monthly basis to the pension fund deposited with the Bank of Taiwan under the name of a pension fund supervisory committee. The pension fund is managed by the government’s designated authorities and therefore is not included in the Company’s consolidated financial statements. Pension cost for an interim period is calculated on a year-to-date basis by using the actuarially determined pension cost rate at the end of the prior financial year. For the three-month and nine-month periods ended September 30, 2024 and 2023, total pension expenses of NT$9 million, NT$11 million, NT$26 million and NT$34 million, respectively, were recognized by the Company.

The issuance plan was authorized for effective registration by the Securities and Futures Bureau of the FSC and accordingly, 27 million shares and 23 million shares of restricted stock for employees were issued without consideration on December 5, 2023 and December 5, 2022, respectively. The life of the plan is four years. Beginning from the end of two years since the date of grant, those employees who fulfill both service period and performance conditions set by UMC are gradually eligible to the vested restricted stocks at certain percentage and time frame. For those employees who fail to fulfill the vesting conditions, UMC will recall and cancel their stocks without consideration. During the vesting period, the restricted stock holders are entitled the same rights as those of common stock holders including the right to receive dividends, but are restricted to sell, pledge, set guarantee, transfer, grant, or dispose the restricted stocks in any other ways. Related information can be obtained from the “Market Observation Post System” on the website of the TWSE.

On June 10, 2020, the shareholders approved a compensation plan in their meeting to issue restricted stocks to qualified employees of UMC without consideration. The maximum shares to be issued are 233 million common shares. UMC is authorized to issue restricted stocks in one tranche or in installments, under the custody of trust institution, within one year from the date of receiving the effective declaration from the competent authority.

The issuance plan was authorized for effective registration by the Securities and Futures Bureau of the FSC and accordingly, 1 million shares and 200 million shares of restricted stock for employees were issued without consideration on June 9, 2021 and September 1, 2020, respectively. The life of the plan is four years. Beginning from the end of two years since the date of grant, those employees who fulfill both service period and performance conditions set by UMC are gradually eligible to the vested restricted stocks at certain percentage and time frame. For those employees who fail to fulfill the vesting conditions, UMC will recall and cancel their stocks without consideration. During the vesting period, the restricted stock holders are entitled the same rights as those of common stock holders including the right to receive dividends, but are restricted to sell, pledge, set guarantee, transfer, grant, or dispose the restricted stocks in any other ways. Related information can be obtained from the “Market Observation Post System” on the website of the TWSE.

The aforementioned compensation costs for the equity-settled share-based payment issued in 2022 and 2020 were measured at fair value based on the closing quoted market price of the shares on the grant date, NT$48.9, NT$44.4, NT$53.0 and NT$21.8 per share, respectively. The unvested restricted stocks issued on the grant date for employees are recognized in unearned employee compensation as a transitional contra equity account and such account shall be amortized as compensation expense over the vesting period.

b.	Stock appreciation right plan for employees
---	---

In June 2021 and September 2020, the Company executed a compensation plan to grant 1 million units and 26 million units of cash-settled stock appreciation right to qualified employees of the Company without consideration, respectively. One unit of stock appreciation right to employees represents a right to the intrinsic value of one common share of UMC. The life of the plan is four years. Beginning from the end of two years since the date of grant, those employees who fulfill both service period and performance conditions set by the Company are gradually eligible to the vested stock appreciation right at certain percentage and time frame. For those employees who fail to fulfill the vesting conditions, the Company will withdraw their rights without consideration. During the vesting period, the holders of the stock appreciation right are not entitled the same rights as those of common stock holders of UMC. The compensation plan, which was implemented in September 2020, expired in August 2024.

The compensation cost for the cash-settled share-based payment was measured at fair value initially by using Black-Scholes Option Pricing Model and will be remeasured at the end of each reporting period until settlement. As of September 30, 2024, the assumptions used are as follows:

	Granted<br> in<br><br> <br>June 2021
Share price of measurement date (NT$/ per share)	$53.80
Expected volatility	26.96%
Expected life	0.69 years
Expected dividend yield	6.46%
Risk-free interest rate	1.33%

According to UMC’s Articles of Incorporation, the employees and directors’ compensation shall be distributed in the following order:

UMC shall allocate no less than 5% of profit as employees’ compensation and no more than 0.2% of profit as directors’ compensation for each profitable fiscal year after offsetting any cumulative losses. The aforementioned employees’ compensation will be distributed in shares or cash. The employees of UMC’s subsidiaries who fulfill specific requirements stipulated by the Board of Directors may be granted such compensation. Directors may only receive compensation in cash. UMC may, by a resolution adopted by a majority vote at a meeting of the Board of Directors attended by two-thirds of the total number of directors, distribute the aforementioned employees and directors’ compensation and report to the shareholders’ meeting for such distribution.

The Company recognized the employees and directors’ compensation in the profit or loss with corresponding other payables during the periods when earned for the nine-month periods ended September 30, 2024 and 2023. The Board of Directors estimates the amount by taking into consideration the Articles of Incorporation, government regulations and industry averages. If the Board of Directors resolves to distribute employee compensation through stock, the number of stock distributed is calculated based on total employee compensation divided by the closing price of the day before the Board of Directors’ meeting. If the Board of Directors subsequently modifies the estimates significantly, the Company will recognize the change as an adjustment in the profit or loss in the subsequent period.

The distributions of employees and directors’ compensation for 2023 and 2022 were reported to the shareholders’ meeting held on May 30, 2024 and May 31, 2023, respectively. The details of distribution were as follows:

	2023	2022
Employees’ compensation – Cash	$5,439,059	$9,160,485
Directors’ compensation	45,000	45,000

The aforementioned 2023 and 2022 employees and directors’ compensation reported during the shareholders’ meeting were consistent with the resolutions of the Board of Directors’ meeting held on February 27, 2024 and February 22, 2023.

Information relevant to the aforementioned employees and directors’ compensation can be obtained from the “Market Observation Post System” on the website of the TWSE.

(6)	On August 31, 2017, the Taichung District Prosecutors Office indicted UMC based on the Trade Secret Act<br>of R.O.C., alleging that employees of UMC misappropriated the trade secrets of MICRON TECHNOLOGY, INC. (MICRON) and of MICRON MEMORY TAIWAN<br>CO., LTD. On June 12, 2020, an adverse ruling issued by the District Court of Taichung in a suit alleged that UMC, two of its current<br>employees and a former employee engaged in the misappropriation of trade secrets. UMC appealed against the sentence. On November 26, 2021,<br>UMC and MICRON announced a settlement agreement between the two companies for all legal proceedings worldwide (the “Settlement Agreement”).<br>Accordingly, MICRON submitted a motion to withdraw the case. On January 27, 2022, the Intellectual Property and Commercial Court announced<br>its ruling of this case and UMC was sentenced to a fine of NT$20 million, subject to a two-year term of probation. On January 27, 2024,<br>UMC completed the probation period successfully and the sentence has been terminated.
---	---

On December 5, 2017, MICRON filed a civil action with similar cause against UMC with the United States District Court, Northern District of California. MICRON claimed entitlement to the actual damages, treble damages and relevant fees and requested the court to issue an order that enjoins UMC from using its trade secrets in question. In accordance with the Settlement Agreement, the court issued a dismissal of the case with prejudice in January 2022.

On January 12, 2018, UMC filed three patent infringement actions with the Fuzhou Intermediate People’s Court against, among others, MICRON (XI’AN) CO., LTD. and MICRON (SHANGHAI) TRADING CO., LTD., requesting the court to order the defendants to stop manufacturing, processing, importing, selling, and committing to sell the products deploying the infringing patents in question, and to destroy all inventories and related molds and tools. On July 3, 2018, the Fuzhou Intermediate People’s Court granted preliminary injunction against the aforementioned two defendants, holding that the two defendants must immediately cease to manufacture, sell, and import products that infringe the patent rights of UMC. The court approved withdrawal of one of the patent infringement actions on our motion while the other two actions are still on trial. In accordance with the Settlement Agreement, UMC submitted a motion to withdraw the case and the application for injunctive procedure. On March 28, 2024, the court approved UMC's withdrawal of actions and the application for injunctive procedure.

The amounts of aforementioned fine from ruling of the Intellectual Property and Commercial Court and the worldwide settlement between UMC and MICRON were recorded in non-operating other losses and have no material financial and operational effect on UMC’s business for the years presented.

(2)	Financial risk management objectives and policies
---	---

The Company’s risk management objectives are to manage the market risk, credit risk and liquidity risk related to its operating activities. The Company identifies, measures and manages the aforementioned risks based on policy and risk preference.

The Company has established appropriate policies, procedures and internal controls for financial risk management. Before entering into significant financial activities, approval process by the Board of Directors and Audit Committee must be carried out based on related protocols and internal control procedures. The Company complies with its financial risk management policies at all times.

(3)	Market risk

Market risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices. Market risks comprise currency risk, interest rate risk and other price risk (such as equity price risk).

Foreign currency risk

The Company’s exposure to the risk of changes in foreign exchange rates relates primarily to the Company’s operating activities (when revenue or expense is denominated in a different currency from the Company’s functional currency) and the Company’s net investments in foreign subsidiaries.

The Company applies natural hedges on the foreign currency risk arising from purchases or sales, and utilizes spot or forward exchange contracts to manage foreign currency risk and the net effect of the risks related to monetary financial assets and liabilities is minor. The notional amounts of the foreign currency contracts are the same as the amount of the hedged items. In principle, the Company does not carry out any forward exchange contracts for uncertain commitments. Furthermore, as net investments in foreign subsidiaries are for strategic purposes, they are not hedged by the Company.

The foreign currency sensitivity analysis of the possible change in foreign exchange rates on the Company’s profit is performed on significant monetary items denominated in foreign currencies as of the end of the reporting period. When NTD strengthens/weakens against USD by 10%, the profit for the nine-month periods ended September 30, 2024 and 2023 decreases/increases by NT$871 million and increases/decreases by NT$60 million, respectively. When RMB strengthens/weakens against USD by 10%, the profit for the nine-month periods ended September 30, 2024 and 2023 decreases/increases by NT$299 million and NT$668 million, respectively. When JPY strengthens/weakens against USD by 10%, the profit for the nine-month periods ended September 30, 2024 and 2023 decreases/increases by NT$100 million and NT$162 million, respectively.

71

Interest rate risk

The Company is exposed to interest rate risk arising from borrowing at floating interest rates. All of the Company’s bonds have fixed interest rates and are measured at amortized cost. As such, changes in interest rates would not affect the future cash flows. On the other hand, as the interest rates of the Company’s short-term and long-term bank loans are floating, changes in interest rates would affect the future cash flows but not the fair value. Please refer to Note 6(11), (13) and (14) for the range of interest rates of the Company’s bonds and bank loans.

At the reporting dates, a change of 10 basis points of interest rate in a reporting period could cause the profit for the nine-month periods ended September 30, 2024 and 2023 to decrease/increase by NT$42 million and NT$31 million, respectively.

Equity price risk

The Company’s listed and unlisted equity securities, investments in convertible bonds and exchange right of the exchangeable bonds issued are susceptible to market price risk arising from uncertainties about future performance of equity markets. The Company’s equity investments are classified as financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income, the investments in convertible bonds which contain the right of conversion to equity instruments are classified as financial assets at fair value through profit or loss, and the exchange right of the exchangeable bonds issued is classified as financial liabilities at fair value through profit or loss as it does not satisfy the definition of an equity component. Please refer to Note 6(2), (3) and (12) for the relevant information.

The sensitivity analysis for the equity instruments is based on the change in fair value as of the reporting date. A change of 5% in the price of the aforementioned financial assets at fair value through profit or loss of listed companies could increase/decrease the Company’s profit for the nine-month periods ended September 30, 2024 and 2023 by NT$257 million and NT$241 million, respectively. A change of 5% in the price of the aforementioned financial assets at fair value through other comprehensive income of listed companies could increase/decrease the Company’s other comprehensive income (loss) for the nine-month periods ended September 30, 2024 and 2023 by NT$701 million and NT$639 million, respectively.

Please refer to Note 12(7) for sensitivity analysis information of other equity instruments or derivatives that are linked to such equity instruments whose fair value measurement is categorized under Level 3.

72
(4)	Credit risk management
---	---

The Company only trades with approved and creditworthy third parties. Where the Company trades with third parties which have less credit, it will request collateral from them. It is the Company’s policy that all customers who wish to trade on credit terms are subject to credit verification procedures. In addition, notes and accounts receivable balances are monitored on an ongoing basis to decrease the Company’s exposure to credit risk.

The Company mitigates the credit risks from financial institutions by limiting its counter parties to only reputable domestic or international financial institutions with good credit standing and spreading its holdings among various financial institutions. The Company’s exposure to credit risk arising from the default of counter-parties is limited to the carrying amount of these instruments.

As of September 30, 2024, December 31, 2023 and September 30, 2023, accounts receivable from the top ten customers represent 60%, 67% and 59% of the total accounts receivable of the Company, respectively. The credit concentration risk of other accounts receivable is insignificant.

(5)	Liquidity risk management

The Company’s objectives are to maintain a balance between continuity of funding and flexibility through the use of cash and cash equivalents, bank loans, bonds and lease.

The table below summarizes the maturity profile of the Company’s financial liabilities based on the contractual undiscounted payments and contractual maturity:

	As of September 30, 2024

(7)	Fair value of financial instruments

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either in the principal market for the asset or liability, or in the absence of a principal market, in the most advantageous market for the asset or liability.

The principal or the most advantageous market must be accessible by the Company.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest.

A fair value measurement of a non-financial asset takes into account a market participant’s ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use.

The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

75

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

Level 1 — Quoted (unadjusted) market prices in active markets for identical assets or liabilities,

Level 2 — Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable,

Level 3 — Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable.

For assets and liabilities that are recognized in the financial statements on a recurring basis, the Company determines whether transfers have occurred between levels in the hierarchy by re-assessing categorization (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period.

Financial liabilities:
Financial liabilities at fair value through profit or loss, current	-	-	655,219	655,219

Fair values of financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income that are categorized into Level 1 are based on the quoted market prices in active markets. If there is no active market, the Company estimates the fair value by using the valuation techniques (income approach and market approach) in consideration of cash flow forecast, recent fund raising activities, valuation of similar companies, individual company’s development, market conditions and other economic indicators.

77

If there are restrictions on the sale or transfer of a financial asset, which are a characteristic of the asset, the fair value of the asset will be determined based on similar but unrestricted financial assets’ quoted market price with appropriate discounts for the restrictions. To measure fair values, if the lowest level input that is significant to the fair value measurement is directly or indirectly observable, then the financial assets are classified as Level 2 of the fair value hierarchy, otherwise as Level 3.

During the nine-month period ended September 30, 2024, there was no transfers between Level 1 and Level 2 fair value measurements. During the nine-month period ended September 30, 2023, due to going public and being listed on the over-the-counter market in May 2023 for the private placement ordinary shares held by the Company's subsidiary, the Company transferred NT$655 million of the financial assets at fair value through profit or loss measured at the end of the reporting period in the quarter from Level 2 to Level 1 fair value measurement.

b.	Assets and liabilities not recorded at fair value but for which fair value is disclosed:
---	---

The fair value of bonds payable is estimated by the market price or using a valuation model. The model uses market-based observable inputs including share price, exchange price, volatility, risk-free interest rates and risk discount rates. The fair value of long-term loans is determined using discounted cash flow model, based on the Company’s current incremental borrowing rates of similar loans.

The fair values of the Company’s cash and cash equivalents, receivables, refundable deposits, other financial assets, short-term loans, payables and guarantee deposits approximate their carrying amount.

Note B: Please refer to the consolidated statements of comprehensive income for the total of realized and unrealized foreign exchange gain and loss. Since there were varieties of foreign currency transactions and functional currencies within the subsidiaries of the Company, the Company was unable to disclose foreign exchange gain (loss) towards each foreign currency with significant impact.

(9)	Significant intercompany transactions among consolidated entities for the nine-month periods ended September<br>30, 2024 and 2023 are disclosed in Attachment 1.
(10)	Capital management
---	---

The primary objective of the Company’s capital management is to ensure that it maintains a strong credit rating and healthy capital ratios to support its business and maximize the shareholders’ value. The Company also ensures its ability to operate continuously to provide returns to shareholders and the interests of other related parties, while maintaining the optimal capital structure to reduce costs of capital.

To maintain or adjust the capital structure, the Company may adjust the dividend payment to shareholders, return capital to shareholders, issue new shares or dispose assets to redeem liabilities.

Similar to its peers, the Company monitors its capital based on debt to capital ratio. The ratio is calculated as the Company’s net debt divided by its total capital. The net debt is derived by taking the total liabilities on the consolidated balance sheets minus cash and cash equivalents. The total capital consists of total equity (including capital, additional paid-in capital, retained earnings, other components of equity and non-controlling interests) plus net debt.

84

The Company’s strategy, which is unchanged for the reporting periods, is to maintain a reasonable ratio in order to raise capital with reasonable cost. The debt to capital ratios as of September 30, 2024, December 31, 2023 and September 30, 2023 were as follows:

	As of
	September 30,<br><br> <br>2024	December 31,<br><br> <br>2023	September 30,<br><br> <br>2023
Total liabilities	$205,801,571	$199,608,355	$197,254,767
