The company said it had entered two multi-year agreements to supply wireless components to the iPhone maker.
The two “statement of work” agreements, plus one signed last year, could lead to $15 billion in future revenue for Broadcom, according to the filing.
Apple and Broadcom resolved a long-running patent suit last year, leading to the earlier SOW agreement, signed in 2019.
Broadcom shares rose $6.79, or 2.1%, to $326.44 in after-hours trading.
Apple ended Thursday’s regular session up $1.53, or 0.5%, at $319.23. Apple shares edged higher in after-hours trading.
