TSMC — August 2026 Revenue Report (Form 6-K)
Filed with the SEC 2026-09-10 under Exchange Act Rule 13a-16/15d-16 (Commission File No. 001-14700), signed by Wendell Huang, SVP and Chief Financial Officer.
Lead
TSMC announced consolidated net revenue for August 2026 of approximately NT$514.81 billion — up 10.1% from July 2026 and up 53.3% from August 2025. Revenue for January through August 2026 totalled approximately NT$3,386.87 billion, up 39.3% against the same period of 2025.
Key Figures
| Period | Net revenue (NT$M) | Change |
|---|---|---|
| August 2026 | 514,806 | +10.1% MoM · +53.3% YoY |
| Jan–Aug 2026 | 3,386,870 | +39.3% YoY |
Read against the June 2026 print already on this rung (tsmc-6k-2026-06-revenue.md: NT$442.68B, +6.2% MoM, +67.9% YoY; H1 NT$2,404.48B, +35.6% YoY), two things move in opposite directions and both matter:
- The monthly level keeps climbing — NT$442.7B (June) → NT$514.8B (August), roughly +16% across two months.
- The YoY rate is decelerating — +67.9% (June) → +53.3% (August) — while the cumulative YoY rate is rising (+35.6% at H1 → +39.3% at eight months). The deceleration is against a hardening 2025 comparison base, not a fall in absolute output.
Why it is on this rung
The hardware rung's supply-side numbers are all memory (HBM4 capability specs, SK hynix margins, TrendForce channel figures). It holds no foundry throughput series. A monthly revenue print is the closest public proxy for whether the advanced-packaging bottleneck — CoWoS allocation, the constraint the rung's other entries describe qualitatively — is loosening, because TSMC does not publish packaging wafer starts. A 10.1% month is consistent with, but does not prove, packaging capacity coming online.
Limitations — and these are load-bearing
- Revenue is not throughput. The figure mixes mix, price and ASP. A 53% YoY revenue gain at flat wafer volume and richer mix is a different world from the same gain on volume, and the 6-K cannot distinguish them.
- No margin, capex, guidance or segment detail. This is a revenue-only monthly filing; nothing here speaks to gross margin or to N2/A16 ramp economics.
- NT$ figures are unaudited and preliminary, per TSMC's standard monthly-report basis.
- The revenue is consolidated across all nodes and customers, so no AI-attributable share can be extracted from it.
What it would take to falsify the packaging-loosening read
A CoWoS-specific capacity disclosure, or a quarterly print showing revenue growth driven by price rather than volume, would break the proxy. Cite this as a run-rate with its as-of month, never as a capacity statement.
