Capacity already limits customer growth

Company disclosure · 2026-07-16

Level classification and financial data

Management states packaging capacity is already limiting customer growth. That meets level 4, not a claim of factory shutdown.

Company perspective on advanced packaging, not all semiconductor manufacturing. Expansion and alternatives could relieve the constraint.

Based on one issuer’s disclosure; this is a scoped research assessment, not an industry-wide survey.

Calculations, sources and history

Revenue growth = (current quarter / same quarter last year − 1) × 100. TWD 1,270.38 billion / TWD 933.79 billion

Gross margin = (revenue − cost of revenue) / revenue × 100. (TWD 1,270.38 billion − TWD 410.07 billion) / TWD 1,270.38 billion

TWD 783.36 billion − TWD 496.00 billion = TWD 287.36 billion

Cash purchases of property, plant and equipment are deducted. Finance-lease principal, acquisitions and financing are excluded; this is not issuer-adjusted free cash flow. TSMC uses its reported quarterly capex. No currency conversion.

Calculations, sources and history

Revenue growth = (current quarter / same quarter last year − 1) × 100. USD 54.229 billion / USD 11.315 billion

Gross margin = (revenue − cost of revenue) / revenue × 100. (USD 54.229 billion − USD 7.182 billion) / USD 54.229 billion

USD 89.675 billion − USD 30.712 billion = USD 58.963 billion

This fourth quarter is calculated as the reported full year minus the first nine months, with both filings linked below.

Revenue：USD 133.188 billion − USD 78.959 billion = USD 54.229 billion

Inventory turns: 3.5. Nine-month excess/obsolescence provision: $72.4m, reflecting weaker forecasts for certain products.
RPO of $2.5bn uses a narrower accounting definition than backlog; do not add them together.

Revenue growth = (current quarter / same quarter last year − 1) × 100. USD 60.801 billion / USD 47.516 billion

Gross margin = (revenue − cost of revenue) / revenue × 100. (USD 60.801 billion − USD 11.33 billion) / USD 60.801 billion

USD 64.088 billion − USD 49.113 billion = USD 14.975 billion

Meta: cash spent on capacity

Spending is measurable; it is not the amount of usable compute or unmet demand.

Q2 2026 capital expenditures including finance-lease principal: $31.08bn; first half: $50.92bn.
2026 full-year $130–145bn is guidance, not completed investment.

Level classification criteria

Assign the highest level directly supported by a current, specific disclosure. Interpreting the source is a research judgment. Levels are ordered categories, not equal measured distances: level 4 does not mean twice the constraint of level 2.

Explicit normal delivery or balanced availability.
Localized or temporary delivery friction.
Current demand exceeds available capacity, or supply is allocated.
Constraints already limit customer production, deployment or growth.
A material stoppage or delivery failure directly caused by supply constraints.

Forecasts, sales growth and expansion alone do not establish a level. Missing evidence does not imply level 1. An editorial rule expires evidence within 120 days of disclosure; scanning news does not extend that period. Updates require a reviewed source. The same publication gate applies to all six observations.

Model: evidence-ordinal-1.0. The former five-factor weighted proposal has been withdrawn because its inputs were not comparable. The replacement pairs this supply constraint level with separately calculated financial checks: revenue growth, gross margin and operating cash after asset purchases. Financial growth is not proof of scarcity. Neither part predicts stock returns.

Earlier research cases · September 10, 2026

These three historical case selections explain the original research questions. The six observations above use the current shared classification; they are company-specific, not an industry shortage index. Earlier source dates below are preserved.

Supplier-reported tightness

Memory supply

Micron says DRAM and NAND demand exceeds supply. Test whether that tightness can sustain profitable pricing.

Direction: Persistence forecast by management; a comparable market-wide trend is not established.

Source published: 2026-06-24

Companies, risks & evidence

Investigate: MU — the reporting issuer. This supply disclosure does not establish sustainable earnings or valuation.

Counterevidence: Shorter delivery times, rising inventory or weaker realized prices would challenge persistent scarcity.

Next check: Compare next-quarter pricing, shipments, inventory and qualified capacity with this disclosure.

Reported execution friction

Power & cooling delivery

Vertiv reported temporary supply-chain congestion and project timing shifts. This is a delivery signal, not proof of market-wide scarcity.

Direction: The issuer characterizes the issue as temporary. This disclosure alone does not establish a persistent industry-wide constraint.

Source published: 2026-07-29

Companies, risks & evidence

Investigate: VRT — direct source company. BE is a separate on-site power research candidate, not a proven beneficiary of this issue.

Counterevidence: Normal delivery and project acceptance without recurring congestion would weaken a lasting-constraint thesis.

Next check: Track recurring delays, acceptance dates, conversion to revenue and margins.

No comparable national lead-time series

Large power transformers

Reports describe extended procurement waits, but the evidence does not establish whether the US national market is tightening or easing today.

Direction: Unknown; no matched US national time series.

Source published: May 2026; underlying inputs include older material.

Companies, risks & evidence

This historical case did not establish GEV or ETN earnings attributable to US large power transformers.

Counterevidence: Comparable, current lead times falling and qualified deliveries catching up with demand.

Next check: Obtain dated, like-for-like lead times by transformer class and geography.

Scope: US Hydropower-focused; generally approximately 100 MVA and above; not the entire US market

Recent publication does not mean recent measurements. Underlying cited inputs include 2022–2024 material; not an independent 2026 market time series.
