What happened

Shares of chip giant Taiwan Semiconductor Manufacturing (TSM -3.90%), better known as TSMC, were trading higher on Thursday after the company reported earnings that beat estimates and provided upbeat guidance for the current quarter.

As of 11:30 a.m. ET today, TSMC's shares were up about 6.5% from Wednesday's closing price.

So what

TSMC reported its fourth-quarter earnings before the U.S. markets opened on Thursday, and they were good: The company earned $1.15 per share on $15.74 billion in revenue, up 6.4% and 5.7%, respectively, from the third quarter -- and both above Wall Street's estimates. 

But the most bullish news was in the company's outlook for 2022. Amid an ongoing global shortage of semiconductors, TSMC is going big -- really big: The company expects between $40 billion and $44 billion in capital expenditures (capex) this year, upgrading and expanding its manufacturing capacity around the world.

TSMC's revenue was up 25% in 2021 from 2020, but chief financial officer Wendell Huang said during the earnings call that the company expects an even larger year-over-year percentage gain in 2022, possibly close to 30%.

"Every year, our capex is spent in anticipation of the growth that will follow," Huang said. He wasn't kidding, and that's why the stock is up today.

Now what

As semiconductor investors know, it takes time to build and equip new chip factories. TSMC spent $30 billion on capex in 2021, moving as quickly as it could to expand capacity amid a demand surge that caught the industry off guard. It's those investments, for the most part, that will power the company's 2022 revenue surge.

But TSMC's clients, which range from mighty Apple (AAPL -1.14%) to many of the world's global automakers, will be happy to hear that the company plans another year of massive capacity upgrades. Judging from this morning's price action, its investors are already pleased.
