Overview

  • Marvell said Celestial AI will receive $1 billion in cash and 27.2 million Marvell shares valued at $2.25 billion, for a total consideration of $3.25 billion.
  • The company expects meaningful revenue from the acquisition to begin in the second half of fiscal 2028, reaching a $500 million annualized run rate in Q4 FY2028 and $1 billion in Q4 FY2029.
