Upside: 20.6%

Core Thesis:
Our BUY rating on Taiwan Semiconductor Manufacturing Company (TSM) is predicated on the conviction that the market has not fully priced in the compounding and durable nature of its dominance as the central nervous system of the global technology ecosystem. TSM is not merely a semiconductor manufacturer; it is the sole gatekeeper to the bleeding-edge computational power fueling the artificial intelligence revolution. Our thesis is built on three pillars:

Structural Dominance in the AI Gold Rush: TSM is the primary, and in many cases, the only viable, manufacturer for the world's most advanced AI accelerators (GPUs, TPUs). With High-Performance Computing (HPC) now constituting a staggering 60% of revenue ^[1], the company has transcended cyclical semiconductor trends, positioning itself as the core infrastructure provider for a multi-decade secular growth story.
A Widening Technological and Economic Moat: The combination of a clear technological roadmap to N2 and A16 nodes, unparalleled manufacturing yields at scale, and a colossal capital expenditure plan ($38-42 billion annually) creates a near-insurmountable barrier to entry. This forces a "winner-take-all" dynamic at the leading edge, granting TSM immense pricing power and customer stickiness.
Advanced Packaging as a Potent Second Growth Engine: Beyond wafer fabrication, TSM's mastery of advanced packaging technologies like CoWoS and 3DFabric is becoming a critical differentiator and a high-margin growth vector. As chiplet architectures become standard for complex AI systems, TSM's ability to integrate heterogeneous dies provides a unique, value-accretive service that competitors cannot easily replicate, effectively capturing more value per silicon system.

While geopolitical risks are palpable and priced in, we argue that TSM's strategic global diversification and its "Silicon Shield" status create a complex equilibrium that mitigates tail risk. The current valuation presents a compelling entry point to own a generational asset at the epicenter of global innovation.

2. Company Fundamentals & Market Positioning

Taiwan Semiconductor Manufacturing Company is the world's largest and most advanced dedicated semiconductor foundry. Its business model is that of a pure-play manufacturer, meaning it does not design or sell its own branded chips. Instead, it serves as the manufacturing partner for the world's leading fabless semiconductor companies, such as Apple, NVIDIA, AMD, and Qualcomm, as well as a growing number of integrated device manufacturers (IDMs) who outsource their most advanced production.

TSM's market position is one of unparalleled dominance. In the critical leading-edge logic segment (defined as 7nm and below), the company commands a market share often estimated to be north of 90%. This monopoly is not accidental but the result of decades of relentless focus on R&D, manufacturing excellence, and massive, sustained capital investment.

The company's operations are segmented by process node technology, with revenue streams derived from fabricating wafers for a diverse set of end markets. As of its latest reporting, these markets are dominated by:

High-Performance Computing (HPC): ~60% of revenue, encompassing AI servers, data centers, and supercomputers.
Smartphones: ~27% of revenue, including high-end application processors and 5G modems.
Internet of Things (IoT) & Automotive: Each contributing ~5% of revenue, representing stable, long-cycle growth areas.

TSM's strategic importance cannot be overstated. It is the foundational layer upon which the modern digital economy is built. Its ability to deliver the most powerful and energy-efficient chips at scale is the primary enabler of transformative technologies, from generative AI to autonomous vehicles and the future of computing.

3. Quantitative Analysis: Deconstructing the Colossus

3.1 Valuation Methodology

To accurately capture the intrinsic value of a company as complex and multifaceted as TSM, a standard, monolithic valuation model is insufficient. The company's business lines, while synergistic, possess vastly different growth trajectories, margin profiles, capital requirements, and risk characteristics. A leading-edge AI wafer (N3) and a mature-node automotive microcontroller (N28) are fundamentally different assets.

Therefore, we have employed a Sum-of-the-Parts (SOTP) valuation methodology. This approach allows us to dissect the company into its core operating segments and value each one individually using a Discounted Cash Flow (DCF) model tailored to its specific dynamics. This granular analysis prevents the high-growth, high-margin segments from being diluted by the more stable, mature ones, providing a more precise and defensible valuation.

Our SOTP framework is structured around five distinct segments:

Advanced Logic (N7 and below): The crown jewel, driven by insatiable AI and HPC demand.
Mainstream & Mature Nodes (>=16nm): The workhorse, serving smartphones, IoT, and automotive markets.
Advanced Packaging & Testing: The emerging growth catalyst, crucial for system-level performance.
Specialty Technologies: High-value niche services with stable demand.
Investments & Non-Operating Assets: The formidable balance sheet fortress of cash and investments.

For each operating segment, we have projected unlevered free cash flows over a five-year explicit forecast period (FY2026-FY22030) and calculated a terminal value based on a perpetual growth model. These cash flows are then discounted to their present value using a segment-specific Weighted Average Cost of Capital (WACC) that reflects its unique risk profile.

3.2 Core Assumptions

Our model is underpinned by a set of meticulously derived core assumptions, grounded in the latest financial disclosures and macroeconomic data.

Risk-Free Rate (Rf): 4.15%, based on the prevailing yield of the U.S. 10-Year Treasury bond as of September 29, 2025 ^[5].
Equity Risk Premium (ERP): We establish a baseline ERP of 6.8%. This is constructed from a base market premium of 5.5%, augmented by a Taiwan-specific Country Risk Premium of 0.8% ^[4] and a Geopolitical Risk Premium of 0.50% to explicitly account for cross-strait tensions, as recommended by our qualitative analysis.
Beta (β): 1.199, reflecting the stock's historical volatility relative to the broader market.
Corporate Tax Rate: A normalized effective tax rate of 20% is applied, consistent with the company's recent tax burden ^[2].
Base-Case WACC: Our blended, company-wide WACC is calculated at 12.11%. This serves as a baseline from which we adjust for individual segment risk.
Currency: All calculations are performed in U.S. Dollars (USD), using an exchange rate of 31 TWD/USD for conversions from the company's TWD-denominated financial statements.
Shares Outstanding: We use a diluted share count of 5.186 billion shares, based on the latest Q2 2025 financial report ^[2].

3.3 Segment Valuation Deep Dive

Segment 1: Advanced Logic (N7 and below) — The AI Engine

This segment is the heart of TSM's value proposition, encompassing the N7, N5, and N3 process nodes that power the world's most demanding applications, primarily AI accelerators for data centers. It accounts for approximately 74% of wafer revenue ^[1] and is the primary beneficiary of the generative AI boom.

Narrative: We model this segment as a high-growth, high-margin engine with significant, front-loaded capital requirements. The demand for AI compute is structural, not cyclical, and TSM's quasi-monopoly at the leading edge grants it significant pricing power. Growth will be driven by both volume (more AI chips) and value (migration to more complex, expensive N3 and N2 nodes).
Key Assumptions:
- Revenue Growth: Starting at an aggressive 20% in FY2026, tapering to a mature 10% by FY2030 as the initial AI build-out phase moderates.
- EBITDA Margin: A robust 65%, reflecting superior pricing power and operational efficiency at scale.
- Capital Intensity: Extremely high, with Capex modeled at 40% of revenue, reflecting the immense cost of building and equipping leading-edge fabs.
- Discount Rate (WACC): 13.0%, a premium to the company average to reflect the higher operational and technological risk associated with the bleeding edge.
- Terminal Growth Rate: 3.5%, reflecting long-term growth in data, AI, and computational demand, exceeding global GDP growth.
Valuation: Our DCF model yields an estimated Enterprise Value of $1,150 billion for the Advanced Logic segment. This constitutes the vast majority of the company's operating value, underscoring its critical importance.

Segment 2: Mainstream & Mature Nodes (>=16nm) — The Stable Foundation

This segment includes a wide range of process technologies that are no longer leading-edge but remain essential for a vast array of products, including mid-range smartphones, IoT devices, automotive microcontrollers, and consumer electronics.

Narrative: This is TSM's cash-cow business. While growth is more modest and tied to broader economic cycles, these nodes are fully depreciated and generate consistent, predictable cash flow. Capital requirements are significantly lower, focused on maintenance and specialty process development rather than new fab construction.
Key Assumptions:
- Revenue Growth: A stable 3-5% annually, tracking global semiconductor market growth ex-HPC.
- EBITDA Margin: A healthy 45%, lower than leading-edge but highly profitable due to lower depreciation costs.
- Capital Intensity: Moderate, with Capex modeled at 25% of revenue.
- Discount Rate (WACC): 11.0%, a discount to the company average, reflecting its lower volatility, established market, and predictable cash flows.
- Terminal Growth Rate: 2.0%, in line with long-term global GDP growth forecasts.
Valuation: Our DCF model yields an estimated Enterprise Value of $180 billion for the Mainstream & Mature Nodes segment.

Segment 3: Advanced Packaging & Testing — The Value Multiplier

This segment, featuring technologies like CoWoS (Chip-on-Wafer-on-Substrate) and 3DFabric, is rapidly evolving from a back-end service to a critical enabler of system-level performance. It is the key to integrating multiple "chiplets" into a single, powerful package, a design essential for modern AI GPUs.

Narrative: We view this as TSM's highest-growth opportunity. Demand for CoWoS capacity currently far outstrips supply, giving TSM immense pricing power. As the industry shifts from monolithic chips to heterogeneous integration, TSM's packaging prowess becomes a second, powerful moat, increasing its share of the value of a final semiconductor product.
Key Assumptions:
- Revenue Growth: Explosive growth, starting at 30% in FY2026 and tapering to a still-strong 15% by FY2030 as capacity catches up with initial demand.
- EBITDA Margin: A strong 55%, reflecting the high value-add and current supply constraints.
- Capital Intensity: High, but less than leading-edge logic, with Capex modeled at 35% of revenue to support rapid capacity expansion.
- Discount Rate (WACC): 13.5%, the highest of all segments, reflecting the nascent nature of the market and the execution risk associated with rapidly scaling new technologies.
- Terminal Growth Rate: 4.0%, higher than logic, as the trend toward advanced packaging is expected to have longer legs.
Valuation: Our DCF model yields an estimated Enterprise Value of $115 billion for the Advanced Packaging segment. While smaller than the logic businesses, its high growth makes it a significant contributor to the overall valuation.

Segment 4: Specialty Technologies — The Niche Profit Pools

This segment provides specialized manufacturing processes for products like RF filters, image sensors, power management ICs, and embedded memory. These are often based on mature nodes but are customized for high performance in specific applications.

Narrative: This is a stable, high-margin business characterized by long product cycles and sticky customer relationships. It serves defensive end-markets like industrial and automotive. While not a primary growth driver, it provides valuable diversification and consistent profitability.
Key Assumptions:
- Revenue Growth: Moderate and steady, averaging 5-8% annually.
- EBITDA Margin: A solid 50%, driven by the value of customization and specialized IP.
- Capital Intensity: Moderate, with Capex at 30% of revenue.
- Discount Rate (WACC): 11.5%, reflecting a risk profile between mature nodes and the company average.
- Terminal Growth Rate: 2.5%.
Valuation: Our DCF model yields an estimated Enterprise Value of $95 billion for the Specialty Technologies segment.

Segment 5: Investments & Non-Operating Assets — The Fortress Balance Sheet

This segment is not valued via DCF but by its book or market value as of the latest balance sheet date (June 30, 2025) ^[3]. It represents the company's immense liquidity and financial strength.

Narrative: TSM's massive cash pile is a strategic weapon. It funds its aggressive capex cycle, allows it to weather any industry downturn, finances R&D, and supports a growing dividend for shareholders. It significantly de-risks the overall investment case.
Valuation:
- Cash & Short-Term Investments: TWD 2,632.7 billion
- Long-Term Investments: TWD 137.4 billion
- Total Value (converted to USD): $89.4 billion

4. Qualitative Analysis: The Narrative Behind the Numbers

Our quantitative model provides a framework for valuation, but the true investment thesis lies in understanding the qualitative forces that drive those numbers. TSM's story is one of compounding competitive advantages, strategic positioning at the epicenter of the AI revolution, and the masterful navigation of a complex geopolitical landscape.

The AI Thesis: Owning the Shovels in a Digital Gold Rush
The rise of generative AI is not an incremental trend; it is a platform shift akin to the internet or mobile computing. At the heart of this shift is an insatiable demand for computational power, a demand that can only be met by the highly specialized, powerful, and efficient chips for which TSM is the world's sole mass-producer. The fact that HPC now drives 60% of TSM's revenue ^[1] is the single most important data point for understanding its future. This transforms TSM from a supplier to the cyclical smartphone market into the core infrastructure provider for a secular, multi-decade build-out of AI capabilities across every industry. Competitors like NVIDIA and AMD may compete for AI software and hardware system dominance, but they all must ultimately rely on TSM's manufacturing prowess. TSM is not betting on a single horse in the AI race; it is the racetrack itself.

The Unbreachable Moat: Technology, Scale, and Capital
TSMC's competitive advantage—its moat—is a masterclass in corporate strategy.

Technology Leadership: With a clear roadmap to N2 (nanosheet/GAA architecture) and A16 (backside power delivery), TSM maintains a 2-3 year lead over its closest rivals, Samsung and Intel Foundry. This lead is not just about feature size; it's about delivering this technology with industry-leading power, performance, and area (PPA) metrics, and crucially, at high yield.
Scale & Yield: Manufacturing at the atomic level is extraordinarily difficult. TSM's decades of accumulated data and expertise allow it to achieve manufacturing yields that competitors struggle to match. This yield advantage translates directly into a cost advantage and reliability that makes switching foundries an existential risk for its customers.
Capital Barrier: The annual capital budget of ~$40 billion is a figure that few corporations or even nations can match. This relentless investment starves competitors of the oxygen needed to catch up, creating a virtuous cycle where TSM's profits fund the R&D and capex that solidifies its future dominance.

Geopolitical Chess: Risk and Resilience
The most significant risk overhang for TSM is its geographic concentration in Taiwan. This risk is real and must be respected. However, the narrative is more nuanced than it appears.

Strategic Diversification: TSM is actively mitigating this risk by building new, advanced fabs in the United States (Arizona) and Japan. While these expansions will create short-term margin headwinds due to higher operating costs, they are a strategically vital long-term de-risking maneuver.
The Silicon Shield: TSM's critical role in the global supply chain serves as a powerful deterrent to conflict. The catastrophic global economic impact that would result from a disruption to its operations gives key global powers—including the United States, Europe, Japan, and even China (which relies heavily on TSM for its own technology sector)—a vested interest in maintaining stability.
Risk Premium: This geopolitical risk is not a secret; it is well-understood and, we argue, largely priced into the stock. For investors willing to underwrite this risk, it creates the opportunity to own a superior asset at a valuation that does not fully reflect its fundamental business dominance. Our inclusion of a specific Geopolitical Risk Premium in our WACC calculation formally accounts for this factor.
