TSM’s Big Test: Can It Keep a 60%+ Gross Margin While Building Expensive Overseas Fabs?
TSM’s Big Test: Can It Keep a 60%+ Gross Margin While Building Expensive Overseas Fabs?
Key idea: Taiwan Semiconductor Manufacturing Co. (TSM) is trying to do two hard things at the same time—keep gross margin around (or above) 60% while also expanding manufacturing outside Taiwan in places like the United States, Japan, and Europe. Those new fabs can be meaningfully more expensive to build and run, but demand for advanced chips (especially AI-related) may be strong enough to offset the pressure.
1) What this news is really about
TSM has long been known for world-class manufacturing efficiency. That efficiency is a big reason its gross margin—the share of revenue left after direct production costs—can be very high compared with many industrial businesses.
But TSM is now executing a global manufacturing shift. Governments and customers want more chips made outside Taiwan for supply-chain resilience, geopolitics, and regional availability. The tradeoff is simple:
- Pro: More capacity closer to customers, diversified supply chain, potential government incentives, and stronger customer trust.
- Con: Higher operating costs overseas can dilute margins—especially during early ramp-up.
Recent commentary around TSM’s margins points to a crucial question: can the company stay near 60%+ gross margin even as overseas sites ramp and remain costlier than Taiwan?
2) A quick refresher: what “gross margin” means for a chip foundry
Gross margin is calculated as:
Gross Margin = (Revenue − Cost of Goods Sold) ÷ Revenue
For a foundry like TSM, “cost of goods sold” includes items such as:
- Materials used in wafer production
- Factory labor and overhead
- Depreciation of extremely expensive tools and cleanroom facilities
- Utilities and equipment maintenance
- Yield-related losses (scrapped or reworked wafers)
Because chipmaking tools are so costly, high utilization (keeping factories busy) and high yields (getting more good chips per wafer) are two of the biggest drivers of a strong gross margin.
3) Why overseas fabs can push margins down
TSM has openly discussed that overseas expansion can dilute margins in the near to medium term. The biggest reasons usually include:
3.1) Higher labor and construction costs
In several overseas locations, wages and contractor costs can be higher than in Taiwan. The supply chain for specialized construction and fab services can also be less mature locally, adding cost.
3.2) Higher utility costs and different operating conditions
Chip fabs are electricity- and water-intensive. Utility pricing, grid stability, and local environmental requirements can vary widely and affect costs.
3.3) Ramp-up inefficiency
New fabs rarely start at peak efficiency. Early phases often have:
- Lower utilization
- Lower yields while processes stabilize
- Higher training and staffing expense
Some analyst commentary has framed this as a margin dilution of a few percentage points during the ramp, potentially widening as multiple sites scale at once.
4) The counterweight: why TSM might still hold 60%+ margins
Even if overseas fabs are more expensive, there are credible reasons TSM may still keep margins elevated—especially if demand stays strong for advanced nodes.
4.1) Pricing power at the leading edge
At advanced nodes (like cutting-edge process generations), the number of companies that can manufacture at scale is limited. When demand is strong, leading-edge production tends to command premium pricing.
4.2) Mix shift toward advanced chips used in AI and high-performance computing
AI data centers and high-performance computing often need the most advanced process technologies and advanced packaging. When that mix becomes a larger portion of sales, it can improve profitability.
4.3) Scale, automation, and process learning
TSM is famous for operational discipline. Over time, the company expects to narrow the cost gap through:
- Automation and standardized manufacturing playbooks
- Higher yields as processes mature
- Higher utilization as customer demand ramps
Several market write-ups note that TSM has guided margin ranges near 60% even while acknowledging overseas dilution—suggesting management believes operational improvements and demand can offset the pressure.
5) Recent margin signals investors are watching
Public discussion around TSM’s recent quarters has highlighted a few headline numbers that shape the debate.
5.1) Evidence of resilience despite higher overseas costs
One widely circulated recap noted that TSM’s gross margin improved year over year in a recent quarter even as overseas expansion costs increased, pointing to the company’s ability to absorb pressure while maintaining strong profitability.
5.2) Guidance still clustered around the 60% neighborhood
Commentary tied to recent outlooks has placed gross margin guidance ranges around the high-50s to mid-60s territory, which is unusual strength for a capital-intensive manufacturing business.
5.3) Industry watchers highlighting a return toward 60%
Trade reporting has also discussed periods where TSM’s margin trends moved back toward the 60% area, connecting those moves with utilization and advanced-node demand, while still noting overseas expansion as a headwind.
6) The “hidden” drivers behind the margin math
When people talk about “60% gross margin,” it can sound like one simple target. In reality, it’s the outcome of many moving parts. Here are the biggest ones.
6.1) Utilization rate: the factory heartbeat
If tools are underused, depreciation costs get spread across fewer wafers, which hurts margins. If tools are highly used, the same fixed costs are spread more efficiently.
6.2) Yield improvements
Yield is about how many chips come out good versus defective. Yield typically improves as a process matures. Strong yield learning is one of the most powerful margin levers a foundry has.
6.3) Product mix and customer mix
Not all wafers are equal. Advanced-node wafers and specialized offerings often carry higher pricing. A shift toward those products can lift gross margin.
6.4) Advanced packaging as a margin enhancer
While the core debate is about fabs, many AI chips also require sophisticated packaging. When packaging and leading-edge manufacturing rise together, they can reinforce profitability—especially if capacity is tight.
7) Why TSM is expanding overseas in the first place
If overseas fabs can reduce margins, why do it at all? Because the strategic benefits can be enormous.
7.1) Customer demand for geographic diversification
Large chip buyers increasingly want manufacturing options outside a single region. It’s about business continuity: fewer single points of failure.
7.2) Government incentives and strategic policy support
Multiple governments have created programs to encourage local semiconductor production. These can come in the form of subsidies, tax credits, or infrastructure support—designed to reduce the effective cost of building and running fabs.
7.3) Talent and ecosystem development
TSM’s overseas presence can help build local supplier ecosystems over time, lowering costs in future years as the ecosystem matures.
8) The competitive context: others are also building
TSM is not alone. Rivals and partners across the industry are also investing heavily in new capacity. Analysts frequently frame this as a global “fab race,” where governments and companies try to secure domestic or regional chip production.
Some market commentary points to major spending plans by other manufacturers as they aim to compete and win government-backed opportunities—raising the stakes for execution and cost control across the entire industry.
9) What could go wrong: realistic margin risks
Even if TSM is best-in-class, there are real risks that could make “60%+” hard to maintain for a period of time.
9.1) Longer-than-expected ramp times
If new overseas fabs take longer to reach high yields and high utilization, dilution could last longer and weigh on margins.
9.2) Demand volatility
Semiconductors are cyclical. If end-demand slows (PCs, smartphones, or even data centers), utilization can drop and margins can compress.
9.3) Cost inflation in equipment and materials
Tooling and materials can face inflation and supply constraints. If costs rise faster than pricing, margin pressure increases.
9.4) Multi-site complexity
Running one world-class manufacturing hub is hard. Running several across continents is harder. Operational complexity can create inefficiencies if not managed tightly.
10) What could go right: realistic upside drivers
On the flip side, there are plausible forces that could keep margins higher than many skeptics expect.
10.1) AI-led demand staying strong
If AI infrastructure build-outs continue, demand for advanced nodes and advanced packaging can remain tight—supporting utilization and pricing.
10.2) Productivity gains offsetting overseas costs
Several analyses emphasize that TSM expects productivity and scale to reduce the cost gap over time, even if there is near-term dilution from overseas sites.
10.3) Incentives narrowing the effective cost gap
Government incentives can effectively “refund” part of the cost burden, improving overall economics compared with a no-support scenario.
11) So, can TSM sustain a 60%+ gross margin?
Balanced answer: It’s plausible—but not guaranteed—and it depends on timing.
Based on the public discussion and analyst-style summaries, the emerging picture looks like this:
- Near term: Overseas expansion can dilute margins by a few points, especially during ramps.
- Offsetting forces: Strong demand for advanced nodes, pricing power, and operational improvements can keep TSM near (or above) 60% at certain points in the cycle.
- Medium term: As overseas sites mature and local ecosystems improve, the margin drag could lessen—though the path may be bumpy.
In plain words: TSM’s margin story is a tug-of-war between higher costs from globalization and higher revenue quality from leading-edge dominance and AI-driven demand.
12) What to watch next
If you’re tracking this story, the most useful signals are not headlines—they are operational indicators that show whether the margin engine is holding up.
12.1) Company guidance ranges vs. actual results
Watch whether reported gross margin keeps landing near guidance ranges, and whether those ranges stay near the 60% line.
12.2) Utilization commentary
High utilization often means strong demand, better absorption of fixed costs, and better margins.
12.3) Updates on overseas ramp milestones
When new sites hit volume production and stable yields, the cost penalty tends to fall.
12.4) Competitive pricing pressure
If competitors add capacity faster than demand grows, pricing could soften and margins could compress industry-wide.
FAQs
FAQ 1: Why are overseas fabs more expensive for TSM?
Overseas fabs can face higher labor costs, different utility pricing, less mature local supplier ecosystems, and early-stage ramp inefficiencies that lower utilization and yields.
FAQ 2: Does a 2%–4% “margin dilution” mean TSM will lose all profitability?
No. A few points of dilution can still leave TSM with strong profitability compared with many manufacturers. The debate is whether it stays above 60% consistently or moves around that level over time.
FAQ 3: Why would customers care where chips are made?
Customers care about supply stability. Geographic diversification can reduce risk from disruptions in any one region and can also support compliance with regional policies.
FAQ 4: How does AI demand help TSM’s margins?
AI and high-performance computing often require advanced process nodes and sophisticated packaging, which can support better pricing and stronger utilization—both of which tend to help margins.
FAQ 5: Can incentives from governments really matter?
They can. Incentives may reduce the effective cost of construction or operations, helping narrow the cost gap versus Taiwan-based production—though results vary by program and execution.
FAQ 6: What’s the simplest way to judge whether TSM is “winning” this margin challenge?
Track (1) gross margin guidance vs. actual, (2) utilization trends, and (3) overseas ramp progress. If margins stay near the 60% zone while overseas capacity grows, that’s a strong signal the strategy is working.
Conclusion
TSM’s overseas fab expansion is a huge, multi-year bet. Yes, it can pressure gross margins in the near term because overseas production is often more expensive—especially at the beginning. But TSM also has powerful defenses: scale, process leadership, and strong demand tied to advanced computing and AI.
Whether TSM sustains a 60%+ gross margin won’t be decided by one quarter. It will be decided by a pattern: steady yield improvements, consistently high utilization, and successful overseas ramp execution—all while staying ahead at the leading edge.
