TSMC’s Q3 2026 Results: Revenue Growth and the 2nm Shift, Explained

NEWS · TECHNOLOGY · 16 OCTOBER 2026

TSMC reported US$46.72 billion in third-quarter revenue, up 41.2% from a year earlier. Its 2nm technology accounted for 8% of wafer revenue. These figures describe different things: the size of the business and the mix of manufacturing technology it sold. Here is how to read both without confusing sales, profit and chip counts.

What changed in the latest results?

TSMC, a foundry—a company that manufactures chips for other companies, released its results on 15 October 2026. The reporting period ended on 30 September and covers July through September. The official earnings release gives the following figures:

Reported measureThird quarter 2026
Revenue in US dollarsUS$46.72 billion
Growth from the previous quarter16.2%, in US dollars
Growth from the same quarter a year earlier41.2%, in US dollars
2nm share of total wafer revenue8%

The next-quarter figure is a forecast. On its results page, TSMC gives fourth-quarter revenue guidance of US$52.3–54.3 billion. Guidance means management’s current estimate. It covers October through December, which is still in progress at this article’s publication.

Why can two growth rates both be correct?

The management report also shows revenue in New Taiwan dollars, written as NT$. In that currency, revenue rose 50.9% from a year earlier. The US-dollar increase was 41.2%. Currency conversion affects the comparison, so keep the currency attached to each rate.

To compare two headlines, write down three things: the measure, the currency and the period. “Revenue, US dollars, compared with a year earlier” is a clear description. A percentage by itself leaves too much room for misunderstanding.

Revenue also differs from profit. The US Securities and Exchange Commission’s guide to financial statements explains the distinction: revenue records sales over a period, while net income is what remains after expenses and other items. A revenue figure alone cannot tell you how much profit a company kept.

What does the 8% 2nm share actually measure?

A wafer is the thin, round base on which chips are made. Here, 2nm names a chip-making technology. TSMC’s technology page calls this family N2.

The reported 8% uses total wafer revenue as its base. It measures a share of sales value. To calculate a share of physical chips, you would need the number of chips in each group. To estimate 2nm wafer revenue in dollars, you would need the matching wafer-revenue total; multiplying the company’s overall revenue by 8% uses a different base.

The management report puts the previous quarter’s 2nm wafer-revenue share at 3%. The change to 8% is 5 percentage points: 8 minus 3. Percentage points describe the distance between two percentages.

A simple example: sales share and item count

This is an invented teaching example, using arbitrary money units—not TSMC’s products or prices. Imagine selling four premium items at 20 units each and 20 basic items at one unit each.

CalculationResult
Premium sales4 × 20 = 80 units
Basic sales20 × 1 = 20 units
Premium share of all sales value80 ÷ 100 = 80%
Premium share of all items sold4 ÷ 24 ≈ 16.7%

The same four items account for a large share of sales value and a smaller share of item count. That is why a revenue-mix headline needs its exact measurement base.

Four checks to keep beside an earnings headline

  1. Check the dates. Separate the announcement date from the months covered.
  2. Match the comparison. Keep the same measure and currency when comparing growth.
  3. Name the base. Ask “a share of what?” before interpreting a percentage.
  4. Mark estimates clearly. Keep reported results separate from management’s outlook.

For a device-buying decision, these company results still leave questions open: the exact product’s price, availability and tested performance need their own evidence. For reading the news, the useful first step is simpler—identify what each number measures.
