Relevant debt reference: TSMC senior unsecured debt and TSMC Arizona guaranteed notes

1. Business Snapshot and Recent Developments

Taiwan Semiconductor Manufacturing Company Limited (“TSMC”) is one of the world’s largest pure-play semiconductor foundries, headquartered in Taiwan. TSMC does not design and sell finished semiconductor products under its own brand. Rather, it is a manufacturing platform company that provides logic semiconductor, mixed-signal, radio frequency, embedded memory, specialty process, advanced packaging, and testing-related services based on customers’ integrated circuit designs. For bond investors, the important point is that TSMC is not merely a growth company benefiting from the semiconductor cycle. It plays a role close to that of the global supply base for advanced logic capacity, while also bearing the substantial capex, Taiwan concentration, customer concentration, export-control, power, water, and earthquake risks required to maintain that role.

A credit analysis of TSMC needs to consider both an exceptionally strong business and financial foundation and geopolitical and operational concentration risks that are sharper than those of a typical highly rated manufacturer. Based on the 2025 Form 20-F, consolidated revenue was NT$3.809 trillion, operating income was NT$1.936 trillion, the operating margin was 50.8%, and operating cash flow was NT$2.275 trillion. Cash and cash equivalents at end-2025 were NT$2.768 trillion, substantially exceeding long-term debt including the current portion. At the same time, the fact that talent, equipment, suppliers, process-improvement capabilities, and tacit knowledge in advanced manufacturing are concentrated in Taiwan itself increases exposure to earthquake, water and power, Taiwan Strait, and US-China regulatory risks.

The largest change from 2025 through 1Q26 is that demand for AI and high-performance computing has become not simply a tailwind, but a central credit issue that is simultaneously lifting the company’s product mix, capex, customer concentration, and pricing power. In the 2025 Form 20-F, High Performance Computing (“HPC”) accounted for 58% of revenue, a substantial increase from 51% in 2024 and 43% in 2023. In the 1Q26 management report, HPC’s share rose further to 61%. Smartphone accounted for 29% of revenue in 2025 and 26% in 1Q26. It remains large, but the core of the current credit story has shifted toward AI/HPC, which requires advanced logic and advanced packaging.

The technology-node mix points in the same direction. In 2025, 3nm, 5nm, and 7nm represented 24%, 36%, and 14% of wafer revenue, respectively, with advanced technologies of 7nm and below accounting for 74% in total. In 1Q26, 3nm was 25%, 5nm was 36%, 7nm was 13%, and technologies of 7nm and below were 74%. A high share of advanced technologies supports pricing and margins, but it also increases the fixed-cost burden in a utilisation downturn and the continuing investment burden for next-generation nodes. In other words, TSMC’s credit quality combines the stability of a mature manufacturer with the cyclicality of advanced-technology investment.

The latest results are very strong. In the 1Q26 results announced on April 16, 2026, consolidated revenue was NT$1.134 trillion, net income was NT$572.5 billion, and diluted EPS was NT$22.08. The company stated that revenue increased 35.1% year on year, while net income and diluted EPS increased 58.3%. Gross margin was 66.2%, operating margin was 58.1%, and net profit margin was 50.5%, indicating exceptionally high quarterly profitability. The 2Q26 guidance was for revenue of US$39.0-40.2 billion, a gross margin of 65.5-67.5%, and an operating margin of 56.5-58.5%. At least as of April 2026, the company was assuming that advanced-technology demand and high utilisation would continue.

Monthly revenue also suggests that the strength in 1Q26 may not have been only a temporary quarterly factor. In the April 2026 revenue report dated May 8, 2026, April 2026 revenue was NT$410.73 billion, and cumulative revenue for January to April 2026 was NT$1.545 trillion, up 29.9% year on year. Monthly revenue does not indicate margins or cash flow, but it is a useful early data point for checking advanced-node supply-demand conditions and utilisation.

However, this strength also increases the investment burden. In the 2025 Form 20-F, TSMC stated that 2026 capex was expected to be US$52-56 billion, with investment directed to 2nm, 3nm, specialty technologies, advanced packaging, and research and development. TSMC’s funding capacity is strong, but when capex is this large in absolute terms, demand-forecast errors, construction delays, subsidy conditions, overseas fab ramp-up costs, and equipment supply constraints can change the view on free cash flow within a short period.

Overseas expansion also has two sides. Expansion into Arizona, Kumamoto, and Dresden strengthens the business base as a response to supply-security requirements from customers and governments. In the short to medium term, however, it adds credit risks related to production cost, yield, talent, supplier management, and subsidy conditions for manufacturing located away from Taiwan’s highly efficient ecosystem.

This report treats TSMC as a highly rated, capital-intensive corporate issuer. It is clearly important to the Taiwanese economy and US semiconductor policy, but that does not imply an explicit government guarantee of TSMC’s debt. TSMC’s credit quality is supported primarily by its own technology, customer base, utilisation, profitability, net cash, and capital-market access. Government subsidies and strategic importance to multiple countries are supporting factors, not legal guarantees of principal and interest payments on bonds.

2. Industry Position and Franchise Strength

TSMC’s business foundation is supported by its overwhelming scale in the semiconductor foundry market, its mass-production capability in advanced nodes, and the stickiness created by linking customers’ design assets with manufacturing processes. In the 2025 market-share data reported by Focus Taiwan citing TrendForce, TSMC’s share of the global foundry market was 69.9%, while the second-ranked Samsung Foundry was at 7.2%. This is secondary information and precise market definitions require caution, but it is sufficient to show that the company is not merely one of the leading suppliers, but a core supplier in the market.

The entry barriers in foundry are not limited to revenue scale. In advanced nodes, miniaturisation, EUV lithography, yield, design kits, IP, EDA collaboration, packaging, supplier management, and joint optimisation with customers are integrated. Customers are not buying cheap wafers; they are buying the ability to mass-produce with the required performance, power consumption, and yield. Once a customer is deeply embedded in TSMC’s design platform and mass-production process, it is difficult to switch on price alone. This supports pricing resilience, utilisation, and long-term order visibility.

TSMC’s pure-play foundry model is also a source of competitiveness. The company does not have its own branded semiconductor products that compete directly with customer semiconductor products. This is important for customers when sharing design information and roadmaps, and it differentiates TSMC from vertically integrated IDMs and competitors with their own products. Semiconductor design companies, cloud service providers, and system companies need to closely align the future roadmaps of their own products with their manufacturing partner, so customer trust has value beyond short-term pricing.

The HPC and advanced-technology mix best illustrates the business foundation from 2025 through 1Q26. In 2025, HPC generated NT$2.193 trillion in revenue and represented 58% of total revenue, increasing by NT$716.0 billion, or 48%, year on year. Smartphone also remained large at NT$1.111 trillion, or 29% of revenue, but its growth rate was limited to 11%. TSMC can no longer be explained only by the smartphone cycle. It is strongly linked to the capex cycle for high-performance computing infrastructure, including AI accelerators, server CPUs, GPUs, ASICs, high-speed networking, and advanced packaging.

However, the shift toward HPC also has the character of concentration rather than diversification. Even if AI-related demand is spread across multiple customers, in practice it depends on the investment plans of large cloud companies, AI semiconductor design companies, major smartphone companies, and system companies. In the 2025 Form 20-F, the largest customer accounted for 19% of revenue and the second-largest customer for 17%. Customer concentration was also significant in 2023 and 2024. Given TSMC’s scale, the product cycles, inventory adjustments, design wins and losses, and pull-ins or push-outs in orders from specific mega-customers can affect the quarterly mix and utilisation. Customer concentration is evidence that TSMC is selected by leading-edge customers, but in credit analysis it should also be treated as a source of earnings volatility.

The geographic customer mix is also skewed. In the 2025 Form 20-F, customers headquartered in North America accounted for 75% of revenue, China for 9%, Asia Pacific for 9%, Japan for 4%, and EMEA for 3%. In the 1Q26 management report, North America-headquartered customers accounted for 76%. This mix reflects the fact that the centre of AI/HPC demand lies with North American semiconductor design companies, cloud service providers, and system companies. From a credit perspective, this is positive in that TSMC is connected to the strong investment capacity and technology roadmaps of US customers, but it also creates exposure to US export controls, China-related restrictions, semiconductor policy, and customer capex budgets.

In peer comparison, it is not sufficient to view Samsung Foundry, Intel Foundry, UMC, and GlobalFoundries simply as providers of “manufacturing capacity.” Samsung Foundry is a business within Samsung Electronics, Intel Foundry is still building a track record with external customers, and UMC and GlobalFoundries are more focused on mature nodes. ASML is an extremely important company in the same semiconductor supply chain, but it is an equipment company, and the nature of inventory, capex, customers, and cyclicality is different. TSMC’s distinctiveness lies in having both advanced-node technology and mass-production scale at the same time.

Advanced-node capability alone is not enough to mass-produce key customers’ products unless it is accompanied by the required volume, yield, customer support, and advanced packaging capacity. Scale alone is not enough to sustain high pricing unless the company can meet the performance requirements of leading-edge customers. TSMC has both, which enables it to generate high operating margins and net cash, but maintaining that advantage makes it difficult to stop R&D and capex.

3. Segment Assessment

TSMC is not a conglomerate with multiple businesses in the traditional sense. Its core business is foundry services. For credit analysis, it is useful to read the company’s official revenue by platform and wafer revenue by technology node as de facto “segments.” By platform, the categories are HPC, Smartphone, IoT, Automotive, Digital Consumer Electronics (“DCE”), and Others; by technology, the categories include 3nm, 5nm, 7nm, 16nm, and 28nm. Profit is not disclosed by platform, so profitability in each area should not be inferred conclusively from revenue mix alone. However, the mix helps assess demand quality, cyclicality, customer concentration, and the direction of capex.

HPC is the largest business driver currently lifting TSMC’s credit quality. Semiconductors for AI accelerators, server CPUs, GPUs, ASICs, high-speed networking, and cloud data centres simultaneously require performance, power efficiency, yield, and advanced packaging capabilities. By combining 3nm, 5nm, 7nm, CoWoS, SoIC, and related capabilities, TSMC provides value beyond simple wafer manufacturing. A rising HPC mix tends to be positive for average selling prices and gross margin. The 1Q26 gross margin of 66.2% and operating margin of 58.1% illustrate how strongly advanced-technology utilisation and pricing affect profitability.

The weakness of HPC is that it pushes up capex when demand is strong and exposes the fixed-cost burden when demand weakens. Semiconductor fabs have large fixed costs after construction. Even if demand falls, depreciation, personnel costs, maintenance costs, power, and baseline material costs do not immediately decline. The strength of AI demand and the maintenance of investment discipline need to be monitored separately.

Smartphone’s share is falling, but it still accounted for 29% of revenue in 2025, or NT$1.111 trillion. Advanced application processors for smartphones are an important foundation supporting mass production of 3nm and 5nm. As HPC grows, dependence on smartphone decreases, but flagship device cycles may still support the utilisation floor for advanced nodes. IoT and Automotive are small in scale, but provide supporting diversification through mature nodes, specialty processes, and long-term customer relationships. However, they do not have the scale to support advanced investment to the same extent as HPC.

The technology-node mix shows profitability and investment burden more directly.

The rise in 3nm’s share from 6% in 2023 to 24% in 2025 and 25% in 1Q26 indicates that TSMC has successfully commercialised its technology roadmap. Advanced nodes initially involve significant burdens from yield, depreciation, customer design changes, and equipment investment. However, if volume increases, utilisation rises, and pricing is maintained, they can lift company-wide gross margin. 5nm also represented 36% of revenue in both 2025 and 1Q26, making it a core node that helps absorb the burden of the 3nm ramp and 2nm investment.

A high share of 7nm and below indicates not only high value-added exposure but also a high capital burden. Advanced nodes require expensive equipment, EUV, cleanrooms, yield improvement, advanced packaging, and stable power and water supply. The technology-node mix is a table that supports credit quality, but also a table for assessing downside sensitivity in a stress case.

4. Financial Profile and Analysis

TSMC’s financial profile is very strong, even among highly rated issuers. From 2023 to 2025, revenue, operating income, operating cash flow, free cash flow, and cash increased substantially, and by end-2025 cash alone materially exceeded long-term debt. In standard manufacturing credit analysis, an increase in capex often leads to higher leverage and weaker FCF. In TSMC’s case, as of 2025, high operating margins and operating cash flow were sufficient to absorb both capex and dividends. The core support for credit quality is not the absolute level of profit, but the cash-generation capacity to maintain net cash even after very large investment.

The table below compares IFRS consolidated financials from 2023 to 2025 based on the Form 20-F with the company’s 1Q26 management materials. The 1Q26 figures are quarterly materials under TIFRS and are not in exactly the same accounting context as the annual audited IFRS statements, but they are used as recent data points for assessing the credit trend.

Comparable long-term debt for 2023, total interest-bearing debt or long-term debt at end-1Q26, share buybacks, and unused bank facilities have not been confirmed in this report and are listed separately under unverified items in the Sources section.

Revenue and earnings growth are supported by AI/HPC demand and the rising share of advanced nodes. In 2025, revenue increased 31.6% year on year, and operating income increased 46.4%. The operating margin rose from 42.6% in 2023 to 45.7% in 2024 and 50.8% in 2025. In a typical manufacturing business, raw materials, labour, depreciation, and R&D costs often pressure margins during growth phases. TSMC is absorbing its large fixed-cost base through high utilisation and lifting margins through advanced-node pricing and mix. This is highly positive for credit quality.

However, the high margin should not be treated as a permanent floor. Semiconductor foundries are sensitive to capacity utilisation. When advanced nodes operate at high utilisation, margins can improve rapidly; when demand corrects, fixed costs including depreciation remain heavy. The Form 20-F explicitly states that a decline in demand or average selling prices could reduce revenue and profit, and that manufacturing facilities are large fixed-cost assets, meaning lower utilisation could significantly pressure margins. The high margins in 2025 and 1Q26 strongly support current credit quality, but in a stress scenario the first indicators to monitor would be gross margin and utilisation.

Cash flow is the most compelling support for TSMC’s credit quality. In 2025, operating cash flow was NT$2.275 trillion, capex was NT$1.272 trillion, and FCF before dividends was approximately NT$1.003 trillion. Even after deducting cash dividends paid of NT$466.8 billion, FCF after dividends was positive at approximately NT$535.8 billion. This shows that the company was able to increase cash even after very large investment and shareholder returns. In 1Q26, the company also remained strong on a quarterly basis, with operating cash flow of NT$699.0 billion and FCF of NT$348.2 billion against capex of NT$350.8 billion.

The capex burden is the largest financial monitoring item going forward. Capex from 2023 to 2025 was NT$949.8 billion, NT$956.0 billion, and NT$1.272 trillion, respectively. The 2026 outlook is US$52-56 billion, materially higher than the US$40.9 billion equivalent in 2025. Capex/revenue was around 33% in 2024 and 2025, which is very high but was absorbed by operating cash flow. If revenue growth continues and utilisation and pricing are maintained from 2026 onward, capex can be read as growth investment rather than credit-negative spending. Conversely, if AI/HPC demand slows while capex rises first, FCF after dividends, net cash, and rating headroom will narrow.

The interest burden is currently small. Finance costs in 2025 were NT$12.4 billion, extremely small compared with operating income of NT$1.936 trillion. In the cash-flow statement in the Form 20-F, interest paid in 2025 was NT$19.1 billion, which is limited relative to operating cash flow. TSMC’s bonds and bank borrowings are primarily fixed-rate. At end-2025, long-term debt consisted mainly of NT dollar and US dollar bonds, with interest rates ranging from 0.41% to 4.63% and remaining maturities from less than one year to 35 years. Higher interest rates affect future issuance costs, but they are not currently pressuring interest-payment capacity.

The balance sheet is strong. At end-2025, total assets were NT$7.933 trillion, total liabilities were NT$2.537 trillion, and total equity was NT$5.396 trillion. Cash and cash equivalents were NT$2.768 trillion, and long-term debt including the current portion was NT$1.033 trillion. Cash alone was approximately 2.7x long-term debt. Cash increased further to NT$3.036 trillion at end-1Q26. Contractual payment obligations, including equipment purchase commitments and one-time customer prepayments, are large, but short-term borrowings were zero at end-2025, and the company is not in a position where liquidity is being pressured by near-term maturities.

The quality of earnings also needs to be assessed in light of the fact that revenue is largely US dollar-based while the financial statements are presented in NT dollars. The Form 20-F states that revenue is substantially denominated in US dollars, while more than half of capex is denominated in currencies other than the NT dollar, mainly US dollars, euros, and yen. The company’s sensitivity analysis indicates that if the US dollar depreciated by 1% against the NT dollar, the operating margin would have declined by approximately 0.3 percentage point based on 2025 results. TSMC manages part of the risk through natural hedges and financial instruments, but FX still affects short-term earnings because it spans revenue, capex, subsidies, overseas investment, and foreign-currency debt.

Overall, the 2025 and 1Q26 financials show that although TSMC is a capex-intensive issuer, it is currently a net-cash credit rather than a leveraged credit. The main question for credit quality is not whether debt repayment capacity is currently insufficient. The question is how far the company can advance overseas expansion and 2nm/3nm/advanced-packaging investment with discipline while AI/HPC-led high profitability continues, and whether it can maintain net cash and high ratings even during a demand correction.

5. Structural Considerations for Bondholders

For bondholders, TSMC is a relatively straightforward issuer, but individual bonds require a separate review of the issuer and guarantee structure. The parent company, TSMC, is a Taiwan legal entity listed on the Taiwan Stock Exchange, with ADSs listed on the NYSE. In the 2025 Form 20-F, TSMC states that the parent company has domestic unsecured bonds, overseas unsecured bonds, and bank borrowings. It also describes Guaranteed Notes issued by TSMC Arizona Corporation, for which the parent company, Taiwan Semiconductor Manufacturing Company Limited, unconditionally and irrevocably guarantees principal and interest.

From the perspective of parent credit, TSMC’s debt is supported primarily by the group’s consolidated cash flow, cash, and capital-market access. At end-2025, long-term debt was approximately NT$1.033 trillion, materially below cash and cash equivalents of NT$2.768 trillion. Therefore, in standard issuer credit analysis, business, capex, and geopolitical risks are more important than where the debt sits. However, the terms of individual bonds, issuing jurisdiction, scope of guarantee, tax gross-up, negative pledge, change of control, cross default, security restrictions, and early redemption provisions should be separately reviewed before investment.

The TSMC Arizona Guaranteed Notes merit particular attention structurally. According to the 2025 Form 20-F, the Guaranteed Notes maturing in 2026, 2031, 2041, 2051, 2027, 2029, 2032, and 2052 were issued by TSMC Arizona Corporation, with the parent company TSMC as guarantor. The fact that the issuer is a US subsidiary is consistent with financing the US fab investment. However, the credit ultimately viewed by bondholders is not the standalone fab cash flow of TSMC Arizona, but TSMC group credit including the parent guarantee. For individual investments, the offering circular or indenture should be checked to confirm whether the guarantee is unconditional, the ranking of the guarantee obligations, the guarantor’s obligations, tax treatment, sanctions and export-control considerations, jurisdiction, and enforceability.

This report does not make definitive statements about the detailed terms of each foreign-currency bond beyond what can be confirmed in the 2025 Form 20-F. Unverified items requiring confirmation include the scope of the parent guarantee, pari passu, negative pledge, change of control, cross default, tax gross-up, withholding tax, restrictions on additional debt, restrictions on granting security, governing law, and the jurisdictions of the issuer and guarantor. Given TSMC’s strong issuer credit, these items are unlikely to determine short-term repayment capacity, but for very long-dated bonds, differences in terms and jurisdiction affect investor protection.

Government subsidies are a structural support, but they are not debt guarantees. In the 2025 Form 20-F, TSMC stated that TSMC Arizona, ESMC, JASM, TSMC Nanjing, and others received subsidies from the governments of the US, Germany, Japan, and China for equipment, construction, and production costs, and that government subsidies in 2025 were NT$76.3 billion. Subsidies reduce the capex burden and demonstrate industrial-policy support by each government, but subsidy contracts have construction schedules and conditions. Delays, failure to satisfy conditions, policy changes, delayed receipt of subsidies, and clawback risk exist. Bondholders should not equate subsidies with a guarantee of principal and interest payments.

Structurally, TSMC is not a holding-company credit like SoftBank Group. Operating cash flow is generated from the same business base, including the parent and key manufacturing subsidiaries, and this is not an issuer that should be analysed primarily through NAV/LTV. That said, because overseas subsidiary-issued bonds, parent guarantees, subsidies, and multiple national jurisdictions are involved, it is not a completely simple parent unsecured bond issuer either. Issuer credit is very strong, but individual bond investment should not skip the review of issuer, guarantor, jurisdiction, and terms.

6. Capital Structure, Liquidity and Funding

TSMC’s liquidity is very strong as of May 15, 2026. Cash and cash equivalents at end-2025 were NT$2.768 trillion, increasing to NT$3.036 trillion at end-1Q26. Short-term borrowings were zero at end-2025, and long-term debt including the current portion was NT$1.033 trillion, of which NT$136.9 billion was classified as due within one year. Simply comparing cash and long-term debt, net cash at end-2025 was approximately NT$1.735 trillion. For bondholders, the important point is to review not only bond maturities but also contractual payment obligations, including equipment purchase commitments and one-time customer prepayments, within the same liquidity framework.

Accordingly, for TSMC, “capex commitments” are a larger item in the liquidity schedule than “debt maturities.” Near-term maturities are not individually pressuring liquidity, but when the 2026 capex outlook rises to US$52-56 billion, contracted investments, operating cash flow, dividends, and external funding need to be assessed together.

Funding access is strong. In the capital management note in the 2025 Form 20-F, the company states that its capital management objectives are to ensure liquidity and maintain a capital structure that supports a solid investment-grade rating. The high ratings of S&P AA- and Moody’s Aa3 support access to domestic and overseas bond markets and bank funding. In 2025 financing activities, bond issuance proceeds were NT$86.9 billion, bond repayments were NT$54.3 billion, long-term bank borrowing proceeds were NT$10.7 billion, and long-term bank borrowing repayments were NT$2.7 billion. This indicates that TSMC funds capex mainly with operating cash flow while using the bond market on a supplementary basis.

Shareholder returns are not currently materially eroding credit quality. Cash dividends paid in 2025 were NT$466.8 billion, slightly less than half of FCF before dividends of approximately NT$1.003 trillion. FCF after dividends was positive at approximately NT$535.8 billion, and cash at end-2025 increased from the prior year-end. In 1Q26 as well, dividends paid were NT$129.7 billion against FCF of NT$348.2 billion, so cash increased even after dividends. TSMC is increasing shareholder returns, but as of 2025, dividends are not at a level that pressures debt repayment capacity.

The path to weaker liquidity is not a sudden debt maturity, but the overlap of capex increases, demand correction, margin decline, dividend maintenance, and start-up losses at overseas fabs. For example, if AI/HPC demand slows while investment in 2nm, 3nm, Arizona, Kumamoto, Dresden, and advanced packaging proceeds as scheduled, operating cash flow would decline while capex remains. At that point, TSMC would need to use net cash, increase bond issuance, or adjust capex. Current headroom is large, but the monitoring indicators are net cash, FCF after dividends, capex/revenue, operating margin, and increased external funding.

7. Rating Reference and Analyst Interpretation

The primary rating information confirmed in this report is that the capital management note in the 2025 Form 20-F states TSMC’s current credit ratings as S&P Global Ratings AA- and Moody’s Aa3. This report has not confirmed the latest rating outlooks, detailed rating rationales, or upgrade and downgrade triggers from the rating agencies’ original publications. Therefore, the following is not a quotation of the rating agencies’ views, but this report’s credit-analysis interpretation based on the reference level of AA-/Aa3.

AA-/Aa3 is very high for a semiconductor manufacturer. Semiconductors normally involve significant earnings volatility because of cyclicality, technology obsolescence, capex, inventory, and customer concentration. The factors this report regards as consistent with that level are the combination of scale and technology in advanced foundry, pricing resilience, substantial cash, low net leverage, strong operating cash flow, and diversified debt maturities. TSMC should not be read as a simple cyclical manufacturer, but as a high-margin platform deeply embedded in customers’ product roadmaps.

The constraints this report believes should be incorporated are not issuer-specific financial weakness, but concentration risks in business and geography. TSMC has net cash and a small interest burden, so its financial metrics alone are very strong. On the other hand, Taiwan concentration, natural disasters, water and power, US-China export controls, concentration in North America customers, AI demand cyclicality, massive capex, and overseas fab ramp-up risk cannot be eliminated by financial metrics alone. Because the original rating-agency triggers have not been confirmed, this report does not make definitive statements. As monitoring hypotheses for this report, however, key concerns include a substantial reduction in net cash, prolonged FCF deficits, lower gross margins and utilisation, weaker capex discipline, and tangible damage to operations or customer demand from geopolitical or export-control events.

Bond investors should use rating symbols as a starting point for investment analysis, not as a substitute for it. The AA-/Aa3 level indicates a high-quality credit with a low default probability, but individual bond tenor, spread, issuer, guarantee, currency, jurisdiction, terms, liquidity, and market reaction to geopolitical events are separate issues. This report has not reviewed market data and therefore does not assess cheapness or richness based on the rating level.

8. Credit Positioning

TSMC’s credit positioning should be considered separately against semiconductor peers, highly rated Asian manufacturers in the same rating area, and critical companies in the supply chain. This report has not reviewed market prices, bond spreads, OAS, or CDS, and therefore does not make a relative-value conclusion. The discussion here qualitatively organises the issuer credit position based on business foundation, financials, capex, and concentration risks that can be confirmed from public information.

In financial comparison, TSMC looks conservative even among highly rated manufacturers. End-2025 net cash, a 2025 operating margin of 50.8%, 2025 FCF before dividends of approximately NT$1.003 trillion, and 1Q26 FCF of NT$348.2 billion are very strong for a capital-intensive manufacturer. At the same time, revenue is concentrated in North America-headquartered customers, HPC, and advanced nodes, and manufacturing capacity is concentrated in Taiwan. Therefore, within the same rating area, the appropriate positioning is “an issuer with very strong financials and business position, but visible geographic and policy risk.”

By tenor, short- to medium-term bonds are likely to reflect cash, operating cash flow, and near-term repayment capacity strongly. Very long-dated bonds such as those maturing in 2041, 2051, and 2052, however, are more exposed to the sustainability of the technology advantage, Taiwan concentration, overseas production migration, AI demand, supply-chain policy, and legal terms.

9. Key Credit Strengths and Constraints

TSMC’s first credit strength is its overwhelming business foundation in advanced foundry. The company is deeply embedded in customers’ design, mass production, yield, packaging, and supply capacity. Process improvement, design support, IP, joint optimisation, and mass-production experience support pricing resilience and high utilisation. This is reflected in the high operating margins in 2025 and 1Q26.

The second strength is the rising share of AI/HPC and advanced nodes, which is improving profitability. HPC accounted for 58% of 2025 revenue and 61% of 1Q26 revenue, while advanced technologies of 7nm and below accounted for 74% of wafer revenue in both 2025 and 1Q26. TSMC is no longer merely a company exposed to the smartphone cycle; it is increasingly a central manufacturing base for AI infrastructure investment.

The third strength is financial conservatism. At end-2025, cash and cash equivalents were NT$2.768 trillion, long-term debt was approximately NT$1.033 trillion, and net cash was approximately NT$1.735 trillion. Operating cash flow in 2025 was NT$2.275 trillion, and FCF after dividends was also positive at approximately NT$535.8 billion. Cash increased to NT$3.036 trillion at end-1Q26. The interest burden is very small relative to operating income, and short-term borrowings were zero at end-2025. This indicates low near-term repayment risk even after taking into account the large capex burden.

The fourth strength is capital-market access and high ratings. The S&P AA- and Moody’s Aa3 levels indicate that the company can use market funding on a supplementary basis. Long-term debt maturities are also widely spread, and foreign-currency bond maturities are diversified, reducing the likelihood that a temporary semiconductor downturn would immediately translate into a liquidity crisis.

The first constraint is the absolute size of capex. The 2026 capex outlook of US$52-56 billion is very large, and regardless of the strength of the financial profile, an incorrect demand forecast could materially pressure FCF. Advanced fabs require time from construction to mass production, yield improvement, and customer product ramp-up. If capex runs ahead while demand weakens, depreciation and fixed costs will pressure margins. TSMC’s credit quality depends not only on whether it can reduce capex, but also on whether it can generate sufficient returns even while increasing capex.

The second constraint is geographic concentration and geopolitics. The manufacturing, technology, and talent base in Taiwan is a competitive advantage, but it concentrates risks related to earthquakes, water shortages, power, the Taiwan Strait, export controls, and supply-chain disruption in one country and region. These risks do not materially affect daily earnings in normal periods, but they cannot be ignored for long-dated bonds.

The third constraint is customer concentration. In 2025, the two largest customers accounted for 19% and 17% of revenue. At TSMC’s scale, the number of leading-edge customers is inherently limited, so concentration is difficult to avoid. The fact that large customers choose TSMC is a strength, but product cycles, inventory adjustments, design changes, use of competitors, supply-chain policies, and regulatory responses by specific customers can affect revenue mix and utilisation. Because the company does not disclose customer names, investors need to monitor this indirectly through revenue mix, platform mix, technology-node mix, and monthly revenue.

The fourth constraint is execution risk in overseas expansion. Arizona, Kumamoto, and Dresden are important investments in response to customer needs and national policies. However, overseas fabs are away from the highly efficient Taiwan ecosystem and therefore initially carry risks related to cost, yield, talent, suppliers, construction, regulation, culture, and subsidy conditions. In its results explanation, the company indicated that gross-margin dilution from overseas fab ramp-up would be 2-3% at the initial stage and widen to 3-4% in the later stage. This does not immediately threaten the currently high gross margin, but over the long term it may act as a cap on profitability.

10. Downside Scenarios and Monitoring Triggers

The most realistic downside scenario for TSMC is a combination of slower AI/HPC demand and front-loaded capex. If monthly revenue or quarterly guidance slows, the HPC or advanced-node mix flattens or declines, and gross margin falls while ordered equipment, fab construction, and advanced-packaging investment remain, FCF after dividends and net cash would decline.

Event risks also cannot be ignored. The Form 20-F describes risks related to US export controls, the annual export licence for TSMC Nanjing, political and military risks, Taiwan-China relations, and policy changes in various countries. Earthquake losses in April 2024 and January 2025, at approximately NT$3.0 billion and NT$5.3 billion respectively, were absorbable. However, a larger operational disruption could affect customer delivery schedules, utilisation, inventory, and customer migration. Overseas fab profitability, customer concentration, and capital allocation, including dividends, share buybacks, and M&A, also need to be monitored in the same framework.

11. Credit View and Monitoring Focus

The current credit quality is sufficiently strong for a highly rated issuer around the AA category, despite cyclicality and geopolitical risk inherent in semiconductor manufacturing. As of May 15, 2026, the direction is stable to slightly positive, because AI/HPC demand, advanced-node mix, gross margin, FCF, and net cash are improving at the same time. There are few signs of short-term credit deterioration.

The core supports for credit quality are a dominant business foundation in advanced foundry, high customer stickiness, a high-value mix centred on HPC and 3nm/5nm, overwhelming operating cash flow, and net cash. The constraints are less about the financial metrics themselves and more about Taiwan concentration, customer concentration, AI/HPC dependence, export controls, natural disasters, water and power, initial profitability at overseas fabs, and the US$52-56 billion scale of 2026 capex. TSMC is not strong simply because it can carry the investment burden; it maintains its strength because it continues to execute that investment successfully.

For bond investors, the highest-priority short- and medium-term indicators are monthly revenue, quarterly gross margin, operating margin, capex, FCF after dividends, and net cash. For long-dated bonds, investors also need to monitor overseas fab profitability, the technology roadmap beyond 2nm, advanced packaging, customer concentration, US-China regulation, Taiwan operational risk, and individual bond terms. For TSMC Arizona Guaranteed Notes, the parent guarantee is central to credit, but before investing investors should confirm the scope of the guarantee, pari passu, negative pledge, change of control, cross default, tax gross-up, governing law, and enforceability in the offering circular or indenture.

On credit fundamentals alone, TSMC can be assessed as a high-quality issuer. However, this report has not reviewed market spreads, OAS, or trading levels, and therefore does not make any recommendation on cheapness, richness, buy, hold, or sell. For short- and medium-term bonds, cash, operating cash flow, and near-term repayment capacity are likely to support credit assessment. For very long-dated bonds, however, geopolitics, sustainability of technology leadership, overseas fab profitability, persistence of AI demand, and covenant protection matter more than current net cash. TSMC should therefore be treated as a credit that is “very strong from a credit perspective, but not so simple that no long-term risk premium is required.” Actual investment decisions require separate confirmation of price, tenor, currency, issuer, guarantee, terms, and liquidity.

12. Short Summary & Conclusion

TSMC is a Taiwan-based pure-play foundry at the centre of the global AI/HPC supply chain for advanced logic manufacturing and advanced packaging. From 2025 through 1Q26, it delivered high revenue growth, operating margins, FCF, and net cash. Its credit quality is consistent with a highly rated issuer around the AA category, and near-term principal and interest payment risk is low. However, massive capex, customer concentration, Taiwan concentration, export controls, and overseas fab ramp-up cannot be ignored for long-dated bonds. Investment analysis should continue to monitor monthly revenue, gross margin, FCF after dividends, net cash, overseas fab profitability, and individual bond terms.
