Investor Relations Previous Earnings Calls

The moat, understandability, and balance sheet health scores reflect a conservative evaluation to ensure a margin of safety in any assessment.

UMC operates as a pure-play foundry, meaning it does not design or market its own branded chips, but instead, focuses entirely on manufacturing chips designed by its customers, therefore, it is their capability of creating a robust and efficient manufacturing base that drives its moat.

Moat Analysis: 3/5

UMC possesses a narrow moat due to a few key elements of its business model:

  1. High barriers to entry: The semiconductor manufacturing industry is extremely capital-intensive. Setting up a fabrication plant requires substantial investments in equipment, technology, and infrastructure, making it extremely difficult for newcomers to enter the market and challenge established players. This is a solid barrier to entry.
  2. Strong relationships with customers: UMC often forms lasting relationships with clients. This leads to some sticky revenues and make the company less likely to lose large clients as the switching costs for designing another chip and finding another foundry are significant for most big semiconductor companies.
  3. Scale and Operational Efficiency: UMC has a network of 12 wafer fabs across Taiwan, Singapore, China, Japan, and the United States. Its size enables UMC to spread its fixed costs, invest more in process technology, and often offer more competitive prices than its smaller rivals, especially in mature nodes and older technologies. These give it some cost advantages. This advantage, while not unassailable, makes the company a preferred choice of many clients.

However, UMC’s moat is not as wide as other chip manufacturers for these reasons. Firstly, unlike some semiconductor companies which also engage in other parts of the value chain, for example, in integrated design and brand ownership, UMC is only a foundry, so while its core business does benefit from the barriers of entry to the chip manufacturing part, the lack of innovation in product development makes the business vulnerable to being overtaken by others with more flexible offerings. Secondly, while UMC does have a good scale, its operating margins are fairly tight at around 15 to 30% compared to those of other high-performance semiconductor companies. Finally, companies with truly wide moats are able to achieve a high market value on the basis of superior technological capabilities. This makes it harder to give UMC a high moat rating compared to others. Therefore, we assign a moat rating of 3 out of 5 to UMC.

Risks to the Moat and Business Resilience

UMC’s narrow moat is vulnerable to several risks.

  1. Technological advancements: Rapid technological changes in the semiconductor industry pose a threat, as newer, more advanced processes can render older manufacturing nodes less relevant. Companies investing more in leading edge innovation rather than mature technologies will threaten to displace those that are slower in innovating. This means UMC may lose out to some competitors as their technology evolves.
  2. Increased competition: The semiconductor market is becoming increasingly competitive, especially among Asian foundries such as GlobalFoundries, Samsung, and TSMC. Competitors are continuously seeking to improve their manufacturing processes and offer lower prices. Thus, if UMC is unable to maintain competitive pricing and operating efficiency, its moat will be further eroded.
  3. Dependence on customer concentration: UMC relies on a few major customers for a large portion of its revenues. If these customers shift their business to a competitor or reduce their orders, the company’s financial performance could suffer greatly.
  4. Geopolitical risks: UMC is based in Taiwan, and that area is under constant threat from geopolitical tensions with China. Geopolitical stability affects the long-term operations and growth prospects of the company.

Despite these risks, UMC’s large size, global footprint, relationships with clients, and its experience in chip manufacturing give it solid business resilience, allowing the company to potentially recover even from major downturns.

Detailed Business Explanation

UMC is a semiconductor foundry, also called a pure-play or dedicated foundry, meaning it only manufactures chips for other fabless companies. This gives them a few specific characteristics that are not common to other semiconductor businesses which are also engaged in the more capital intensive part of the semiconductor process, design of the chips, or even the branding and sale of the finished product. These are:

  • Revenue Distribution: The company generates revenues mainly by manufacturing wafers for customers in industries like communications, consumer electronics, and computing. Its clients are primarily chip designers and fabless companies. The geographical regions are diverse but majorly located in Asia and America. Its revenue distribution is fairly concentrated and depends on a small subset of clients.
  • Industry Trends: The semiconductor foundry sector is characterized by the increasing complexity of fabrication processes and the rising costs of new technology development. Demand for semiconductors is primarily driven by a rising tide of technological advancement across multiple industries and consumer segments. The move towards advanced packaging and the need for more complex chips are also driving growth in the foundry industry. There is also considerable growth from high performance computing and AI industries. Given this, advanced process nodes will continue to become increasingly popular for high performance semiconductors. However, mature nodes continue to be useful for chips where performance is less important than cost.
  • Margins: Historically, margins in the semiconductor foundry segment are very inconsistent. The high cost of entry and capital expenditure make it a high margin business in some aspects, but high capital intensity and competition mean profitability could also fluctuate a lot. For the last 10 years, gross margin has consistently remained between 15-30%, while operating margins have typically remained slightly lower. These margins are fairly low compared to companies who design the chips and control the process.
  • Competitive Landscape: UMC operates in a highly competitive landscape. The primary competitors are TSMC, GlobalFoundries, and Samsung. UMC has been a long-term player in the space, and is generally considered one of the top 5 foundries, however, the market is still very concentrated and more than half of the market share belongs to TSMC.
  • What Makes UMC Different? UMC’s unique selling proposition is its focus on providing manufacturing services at competitive prices, especially for mature and legacy nodes. The company specializes in delivering high-quality chips while keeping its costs lower than other companies. UMC has a very large footprint compared to many other foundries, which allow it to give its clients flexible geographic options and more capacity if it is needed.

The financial health of UMC’s business is relatively good.

  • Profitability: For the past decade, the gross profits have stayed fairly consistent at between 20-30%. However, the company is subject to high capital expenditures, and so net profitability is somewhat depressed. There is some stability in operational performance given by long-term contracts with clients, but the margin of error for the company is very low. Given this, even minor market problems can lead to a sharp downturn in profitability. This is a negative factor of the company’s financials.
  • Leverage: UMC has high leverage. The debt to equity ratio of the company is 1:1, and that will need to be lowered for future solvency. The use of both debt and equity to fund its operations, however, is not necessarily a concern. UMC has a high degree of control over its operations and that gives the company an ability to service debt as needed. The current debt is around 10% of the total capitalization of the company.
  • Cash flows: UMC’s cash flows are generally positive, and it typically generates cash through its operations. The company has been able to pay down its debts using its free cash, and it appears to be in a strong financial position with respect to this. Also, the company seems to be growing it cash pile.

Understandability: 3 / 5

UMC is a semiconductor foundry business that has many different elements that are not always easy to understand. The supply chain, its customers, and technological risks associated with it can make the business hard to analyze for a new investor. However, it is still not an extraordinarily difficult business model to grasp given a decent overview. Thus, an understandability rating of 3 out of 5 is given to UMC.

Balance Sheet Health: 4 / 5

UMC’s financial statements are fairly strong. It has a long history of operations with good profitability and cashflows. Despite having a large amount of debt, the company seems to be able to handle it appropriately, as the interest expense is not too large compared to its income. With low leverage (comparatively) and decent profit margins, the company is rated at 4 / 5.

Recent Concerns, Controversies and Problems

UMC, like the rest of the semiconductor industry, has been undergoing a period of rapid shifts. The company had a negative reaction to its guidance in its last earnings call due to macro uncertainty, and this lowered the stock prices. In response to that, the management has expressed the intention of reducing capital expenditure, lowering production, and managing costs. As long as management can guide the company correctly through this period, UMC will likely be able to remain competitive and grow. Also, UMC’s reliance on China for supply is also a problem that the company may face in the future as geopolitical tensions continue to rise. Also, the recent Taiwan tensions are adding a bit more volatility into the company’s stock price. However, the long term is still bright for the company, as the demand for mature node semiconductors are rising, which is where UMC’s expertise lies. Management has also noted in the earnings call that they continue to pursue their sustainability agenda, with some of its plants already being run fully by clean energy, which will be important in attracting many large technology clients in the future. In short, UMC is going through a rocky patch, but its future is still bright as the industry continues to grow.
