Taiwan Semiconductor Manufacturing stock has delivered a very large 337.6% return over the past three years, yet the current checks suggest the shares may still trade below an intrinsic value estimate and below what earnings multiples would usually imply.

• A roughly 3.4x gain over three years signals that expectations baked into Taiwan Semiconductor Manufacturing's share price are far higher today than they were a few years ago.
• Heavy investment in advanced chip capacity for AI and data centers can support long term cash flow. However, the scale of planned capital spending may weigh on margins and free cash generation if demand or pricing disappoint.
• On Simply Wall St's valuation checks, Taiwan Semiconductor Manufacturing scores 4 out of 6, which points to a mixed picture rather than a clear bargain or clear overvaluation.

The issue now is whether the combination of a 13.0% discount to an intrinsic value estimate and supportive market multiples still offers enough potential upside to justify the risks after such a strong multi year run.

Is Taiwan Semiconductor Manufacturing Still Cheap on Cash Flow?

The Discounted Cash Flow (DCF) model for Taiwan Semiconductor Manufacturing focuses on the cash the business can return to shareholders over time. On this framework, the latest twelve month free cash flow sits at about NT$1.1t, with projections assuming growing cash generation rather than a shrinking base.

When those cash flows are discounted back, the model points to an estimated intrinsic value of about $488 per share, which is roughly 13.0% above the current share price estimate used in the calculation. TSMC’s heavy planned spending on advanced fabs in Arizona and other regions is captured in these forecasts, yet the cash flow outlook in this model still supports a higher value than the market price.

Because TSMC plans to invest an additional $100b in U.S. chip production, the gap between price and the intrinsic value estimate may partly reflect concern about how that larger capital program interacts with long term cash returns.

On this DCF view, Taiwan Semiconductor Manufacturing stock currently appears undervalued relative to its estimated intrinsic value.

Is Taiwan Semiconductor Manufacturing Still Cheap on Earnings?

The P/E ratio fits Taiwan Semiconductor Manufacturing well because earnings remain a core anchor for how the market prices major chip foundries. Right now, the stock trades on about 28.2x earnings, compared with an industry average P/E of roughly 60.4x and a peer average around 74.0x.

The fair P/E ratio implied by Simply Wall St’s model is 58.2x. This reflects what investors might typically pay for Taiwan Semiconductor Manufacturing given its size, margins, growth profile and risks. Against that benchmark, the current 28.2x multiple sits at a large discount, suggesting the stock price does not fully reflect the earnings multiple that would usually be applied to a business with these characteristics.

On this P/E comparison, Taiwan Semiconductor Manufacturing stock appears undervalued relative to both its tailored fair multiple and broader semiconductor peers.

The Taiwan Semiconductor Manufacturing Narrative: What Would Justify Today's Price?

Simply Wall St Narratives pick up where the valuation puzzle for Taiwan Semiconductor Manufacturing leaves off, by spelling out which assumptions about growth, margins and earnings would need to hold for the stock to be worth materially more or less than it is today on the market. Each narrative links a specific fair value to a particular storyline about Taiwan Semiconductor Manufacturing's potential catalysts and key risks, so you can track over time which version appears to be unfolding, and they are accessible on Simply Wall St's Community page.

The Taiwan Semiconductor Manufacturing community is sharply split, with some investors focused on capacity and packaging upside while others fixate on geopolitical and pricing risk.

Bull case: 6% undervalued

"The meat moving the needle right now is CoWoS packaging...

Bear case: 11% overvalued

"That tension, between the most magnificent business economics I have ever studied and the most sobering geopolitical risk I have ever priced, is the entire intellectual challenge of owning TSMC...

The Bottom Line

For Taiwan Semiconductor Manufacturing, both the Discounted Cash Flow (DCF) intrinsic value estimate and the earnings multiple view indicate that the stock is trading on the cheap side, even after a very strong three year return. The DCF suggests a meaningful discount to intrinsic value, while the current P/E sits well below the stock’s tailored fair ratio and sector averages, despite broader valuation checks landing in mixed territory. The key question from here is whether Taiwan Semiconductor Manufacturing can turn heavy capital investment and geopolitical risk into durable cash generation without eroding margins, or whether the current discount will end up being a value trap rather than an opportunity.
