Broadcom (NASDAQ: AVGO) shares climbed as much as 3.9% Thursday morning, holding onto a 3% gain as of 11:40 a.m. ET, continuing a rally that began the prior session.

The gains were driven by two major partnership developments involving some of the largest technology companies in the world.

Apple (NASDAQ: AAPL) announced a sweeping multiyear agreement to spend more than $30 billion on Broadcom chips over the next five years.

The pair plan to “design and produce custom silicon components and cutting-edge wireless connectivity technologies for a wide range of Apple products,” according to a joint press release.

The deal includes a $1.5 billion expansion and modernization of Broadcom’s manufacturing facility in Fort Collins, Colorado, reinforcing the chipmaker’s domestic production footprint.

The $30 billion investment will underpin the production of more than 15 billion semiconductors manufactured within the United States.

The planned expansion will enable Broadcom to produce advanced radio frequency components, including FBAR filters, along with wireless connectivity technologies that power 5G, Bluetooth, Wi-Fi, and GPS functions in iPhones.

Adding further momentum to the stock, a Reuters report revealed that Meta Platforms (NASDAQ: META) plans to begin production of its own in-house artificial intelligence chip, code-named Iris, as early as September.

The Iris chip was designed by Broadcom and is intended to improve AI capabilities across Facebook and Instagram, according to the report.

Broadcom’s growing backlog and expanding partnerships with major technology firms have not yet pushed its valuation into expensive territory, with the stock currently trading at 21 times next year’s expected earnings.

The company’s price/earnings-to-growth ratio, which accounts for its growth trajectory, stands at 0.53, well below the threshold of 1 that typically signals an undervalued stock.

Investors watching the semiconductor sector are taking note, as Broadcom’s dual role as both a custom chip designer and wireless component manufacturer positions it at the center of two of the industry’s most powerful spending cycles.

The Apple deal in particular signals a sustained, long-term demand commitment that provides Broadcom with significant revenue visibility over the coming half-decade.

With attractive valuation metrics and high-profile clients deepening their reliance on its technology, Broadcom continues to strengthen its case as one of the most competitively positioned names in the semiconductor industry.
