United Microelectronics Corporation (UMC) — FY2022 Form 20-F
Reporting period: Fiscal year ended December 31, 2022. This is an annual report, not a standalone Q4 filing; quarterly Q4 results are not clearly provided in the filing text. Financial statements are prepared under IFRS as issued by the IASB and audited by Ernst & Young, which gave an unqualified opinion.
Business context
UMC is a global semiconductor foundry manufacturing wafers to customer designs, with fabs in Taiwan, Singapore, China and Japan. Its business is capital intensive and exposed to semiconductor cycles. In 2022, wafer sales were supported by higher selling prices, product mix and demand, although management also described an industry downturn and expected inventory correction.
Key financial metrics
| Metric | FY2022 | FY2021 |
|---|---|---|
| Revenue | NT$278.71bn (US$9.07bn) | NT$213.01bn |
| Gross profit / margin | NT$125.76bn / 45.1% | NT$72.05bn / 33.8% |
| Operating income / margin | NT$104.29bn / 37.4% | NT$51.69bn / 24.3% |
| Net income attributable to parent shareholders | NT$89.48bn | NT$51.25bn |
| Basic / diluted EPS | NT$7.40 / NT$7.16 | NT$4.27 / NT$4.19 |
| Operating cash flow | NT$145.86bn | NT$90.35bn |
| Cash and cash equivalents at year-end | NT$173.82bn | NT$132.62bn |
| Capital expenditures | NT$82.42bn | NT$50.12bn |
Revenue rose 30.8% and parent-attributable net income rose 74.6%. Management attributed revenue growth to a 21.3% increase in average selling price, higher wafer shipments (9.945 million versus 9.862 million 8-inch-equivalent wafers), and a 6.4% depreciation of the New Taiwan dollar against the U.S. dollar. Capacity utilization was 100.6%, down from 104.4% in 2021.
Net cash used in investing activities was NT$54.43bn, including NT$80.13bn of cash purchases of property, plant and equipment; financing activities used NT$57.25bn, including NT$37.45bn distributed from additional paid-in capital and a net reduction in bank loans. The current ratio was approximately 2.24, based on current assets of NT$252.37bn and current liabilities of NT$112.61bn. Year-end bonds payable were NT$28.18bn and long-term loans, including current portions, were NT$19.28bn. Lease liabilities were NT$5.74bn. UMC reported net debt of NT$28.02bn and a debt-to-capital ratio of 7.99%, down from 16.95%.
Material changes and notable items
- Gross margin expanded 11.3 percentage points and operating margin expanded 13.1 points, reflecting higher average selling prices and currency effects; operating costs rose 8.5%, slower than revenue.
- Revenue mix shifted toward 28nm and below, which represented 23.8% of foundry revenue, versus 19.9% in 2021. Communication remained the largest wafer application at 45.2%; “others” increased to 14.0% from 10.5%.
- Capital spending increased substantially. The company reported NT$69.22bn in construction contracts, with approximately NT$41.96bn not yet recognized. Total contractual cash obligations were NT$216.54bn, including NT$118.58bn due within one year.
- Non-operating income declined 21.7% to NT$5.33bn, including a swing in fair-value gains and losses to a NT$1.13bn loss and lower equity-method earnings, partly offset by higher interest and foreign-exchange income.
- Inventory increased to NT$31.07bn from NT$23.01bn. The auditor identified valuation of slow-moving inventories as a critical audit matter.
- UMC reported a NT$20m fine and two-year probation in the Taiwan Micron trade-secret case. The worldwide settlement resolved the U.S. civil case; UMC stated the fine and settlement had no material financial or operational effect for the periods presented.
Outlook, risks and capital allocation
Management gave no quantified revenue, margin or utilization guidance in the filing. It cited long-term demand drivers including 5G, IoT and electric vehicles, but also warned of a semiconductor downturn, customer inventory corrections, cyclical demand and potential future foundry overcapacity. Expansion is intended to be supported by customer multi-year supply arrangements.
- A new Singapore 300mm fab is planned for 30,000 wafers per month, using 22nm and 28nm processes, with production expected to begin in the first half of 2025.
- Key risks include customer concentration (top ten customers generated 52.4% of revenue; the largest customer generated 8.6%), U.S.-China trade and export restrictions, Taiwan Strait tensions, foreign-exchange movements, supply-chain constraints, and Taiwan earthquake, drought, water and power risks.
- UMC proposed a FY2022 cash dividend of NT$3.60 per share, subject to shareholder approval. Separately, shareholders approved a NT$3.00-per-share distribution from additional paid-in capital in 2022.
- Management reported effective disclosure controls and internal control over financial reporting as of year-end; the independent auditor also gave an unqualified internal-control opinion.
Most important facts for investors to verify
- Whether demand, selling prices and capacity utilization held up after the filing’s described industry downturn and customer inventory correction.
- Whether the sharp margin expansion was sustainable, particularly given its reliance on pricing, product mix and currency depreciation.
- Execution, funding, customer commitments and expected returns for the elevated capital program, including the Singapore fab and Taiwan expansion.
- Customer concentration, receivables and inventory quality; the filing highlights slow-moving inventory valuation as a key audit judgment.
- Actual timing and approval of the proposed NT$3.60 dividend, and cash needs relative to contractual obligations and planned capital spending.
