Marvell Technology (MRVL) Acquisition of Celestial AI: Market Impact & Analysis

This analysis is based on the CNBC report [1] and internal analytical data [0] regarding Marvell Technology’s (MRVL) acquisition of Celestial AI. On December 2, 2025, MRVL announced the deal: a base price of $3.25 billion in cash and stock, with potential milestone payments bringing the total to $5.5 billion if Celestial AI achieves $2 billion in cumulative revenue by fiscal 2029. The announcement was paired with MRVL’s Q3 2026 earnings beat (adjusted EPS $0.76 vs. $0.73 expected; revenue $2.08B vs. $2.07B expected) [1].

MRVL shares reacted positively, rising 15% in extended trading on December 2, 2025 [1], reflecting investor optimism about Celestial AI’s optical technology enhancing MRVL’s semiconductor networking and AI infrastructure capabilities. Contrary to a Reddit user’s bullish claim that POET Technologies (POET) could benefit as a Celestial AI customer, POET’s stock closed down 1.27% that day, with no verifiable evidence of their customer-supplier relationship found [0][1].

For dilution risk: With MRVL’s market cap at ~$80 billion [0], a 50% stock component of the base $3.25 billion deal would result in ~2% dilution. If full $5.5 billion milestones are reached (50% stock), dilution could rise to ~6.8% [0][1].
