Apple has issued a press release to let everyone know that it is involved in the plan for Broadcom to expand its manufacturing facility in Fort Collins, Colorado. While the press release is full of numbers, the actual details are still unclear.

Broadcom currently supplies important radio technology parts to Apple. While Apple is moving to its own modems for cellular (C1, C1X) and Wi-Fi/Bluetooth (N1), there are still lots of radio parts needed in Apple products, including antenna signal management, NFC, and more. The press release calls out FBAR filters, for example, which are a special kind of high-frequency radio filter.

The release says Apple will invest $30B into Broadcom, and some of the financial press has run with that number, but it is unclear what exactly that means. In this context, “invest in,” typically means “agrees to spend that much on products or services over a certain span of time.” Apple was going to buy billions of dollars worth of Broadcom parts over the coming years, and the “$30B investment” likely means Apple just agreed to spend that much. There is no timeframe given, nor any context of how much of an increase in spend that would be, if any.

Some reports have loosely tied Apple to a $1.5B investment to help Broadcom expand its manufacturing plant in Fort Collins, Colorado. However, Apple’s press release makes it clear that it’s Broadcom spending that money, and that Apple’s $30B agreement simply enables them to do it: “This new agreement… will enable Broadcom to expand and modernize its manufacturing facilities in Fort Collins, Colorado, with a $1.5 billion capital expenditure investment.”

The press release closes with another vague, context-free number that Apple likes to throw around: “These investments are part of Apple’s commitment to invest $600 billion in the U.S. economy over four years, supporting manufacturing, job creation, and technology development across the country.” Apple’s $600B investment is not all new spending on manufacturing, but is the sum total the company will spend in the United States, including salaries, offices, electricity, buying parts, shipping, advertising, and more.
