Revenue growth reflected 10.6% higher wafer shipments and a 14.6% increase in average selling price versus 2020, partly offset by a 5.3% appreciation of the NT dollar against the U.S. dollar. Capacity utilization reached 104.4%, compared with 96.9% in 2020. The 28nm-and-below share of foundry revenue rose to 19.9% from 13.6%.
Balance sheet and liquidity
- Cash and cash equivalents were NT$132.6bn at year-end, up from NT$94.0bn.
- Current assets were NT$233.3bn and current liabilities NT$108.2bn, implying a current ratio of approximately 2.2.
- Reported bonds payable were NT$40.5bn; short-term loans were NT$1.9bn and long-term loans NT$36.6bn. These figures imply approximately NT$79.1bn of bonds and loans, before lease liabilities. Cash exceeded these borrowings by approximately NT$53.5bn.
- Contractual cash obligations totaled NT$178.9bn, of which NT$94.8bn was due within one year. The filing includes obligations not yet recorded on the balance sheet in this total.
Material changes and notable items
- Operating costs rose only 2.3% while revenue increased 20.5%, supporting the sharp improvement in gross and operating margins. Management attributed the margin gains principally to strong demand and higher utilization.
- Net income included a substantial increase in equity-method earnings from associates and joint ventures, to NT$5.2bn from NT$1.3bn. Non-operating income and expenses were a net gain of NT$6.8bn.
- UMC paid NT$19.9bn in cash dividends during 2021, versus NT$9.8bn in 2020. A further distribution of approximately NT$3 per share from capital surplus was proposed in February 2022 and remained subject to shareholder approval.
- UMC issued domestic bonds and US$400m of zero-coupon exchangeable bonds in 2021. The exchangeable bonds are exchangeable into Novatek shares held by UMC; no bonds had been exchanged by year-end.
- The Micron trade-secret dispute was settled worldwide. In January 2022, a Taiwan court imposed a NT$20m fine with a two-year probation term; the U.S. civil case was dismissed with prejudice. UMC said the matters had no material financial or operational effect. A separate U.S. securities class action was settled for US$3m in 2021.
Outlook, management commentary and risks
Management described wafer demand as outpacing supply, citing 5G, IoT, electric vehicles and related technologies, as well as pandemic-accelerated digitalization. The company planned customer-supported capacity expansion and emphasized return-focused capital spending. In February 2022, the board approved a new Singapore facility, with first-phase monthly capacity of 30,000 wafers, 28nm and 22nm processes, and production expected to begin in late 2024. UMC also announced expansion of Fab 12A in Taiwan supported by customer multi-year agreements and loading protection. The filing does not provide a clear numerical full-year 2022 revenue, margin or earnings forecast.
- Key operating risks include semiconductor cyclicality, pricing and potential industry overcapacity; customer concentration (top ten customers represented 54.5% of 2021 revenue); and dependence on timely access to equipment, materials, utilities and skilled labor.
- Management highlighted supply-chain disruption, COVID-19 impacts, foreign-exchange movements, and geopolitical and trade tensions involving Taiwan, the United States and China.
- Natural hazards and resource constraints are material exposures: UMC cited Taiwan’s severe 2021 drought, water availability, power interruptions and earthquake risk.
- Potential tax changes and reduced or revoked government incentives could affect future tax expense. The company reported NT$2.995bn of tax savings from tax exemptions and NT$958m from other tax incentives in 2021.
- UMC reported effective disclosure controls and internal control over financial reporting; its auditor issued unqualified opinions on the financial statements and internal controls.
Important facts for investors to verify
- Review the audited financial statements and notes for the composition and maturity of debt, the NT$94.8bn of obligations due within one year, and the nature of guarantee deposits and other financial liabilities.
- Assess whether utilization above 100%, higher average selling prices and margin expansion are sustainable as supply and demand evolve.
- Verify the status, customer commitments, funding and execution milestones for Fab 12A expansion and the Singapore fab, including the expected late-2024 start of production.
- Check subsequent developments in the USCXM loan covenant waiver, which was obtained in February 2022, and the announced 2022 USCXM investment transaction.
- Confirm shareholder approval and final terms of the proposed NT$3-per-share capital-surplus distribution, and monitor dividend capacity alongside the elevated capital expenditure program.
