Marvell Technology (MRVL) shares plummeted 6.32% in after-hours trading on Tuesday, following the release of its third-quarter earnings and the announcement of a major acquisition.

The chipmaker reported Q3 adjusted earnings of $0.76 per share, beating estimates, and revenue of $2.08 billion, up 37% year-over-year. However, its Q4 guidance of $0.79 per share (plus or minus $0.05) matched analyst expectations, failing to impress investors hoping for a stronger outlook.

Additionally, Marvell announced the acquisition of Celestial AI in a $3.25 billion deal, aiming to bolster its data center connectivity solutions. While strategic, the deal raised concerns about integration costs and the timeline for meaningful revenue contributions, which are expected only by the second half of fiscal 2028.
