Marvell agrees $115 billion Lumentum deal; AMD data-center sales surge; China chip restrictions affect suppliers

Marvell agreed to acquire Lumentum in a $115 billion all-stock deal, whose value fell as the companies lost $91 billion in market value amid merger doubts. AMD will pay about $2.9 billion for AI chip startup Taalas. ¹²³
China-related chip restrictions affected Nvidia, TSMC and SK hynix. About 600,000 Nvidia AI chips awaited Chinese import approval in Hong Kong; the US ordered TSMC to halt advanced chip exports to China and withheld equipment export approvals for SK hynix’s Chinese plant. ⁴⁵⁶
AMD’s data-center growth drove a record quarter: revenue rose 45% to $13.4 billion, with data-center sales nearly doubling to $8.5 billion. AMD forecast about $17 billion in fourth-quarter revenue, easing AI spending fears, although gaming revenue fell 40%. ⁷⁸⁹
Intel shares plunged 28% despite quarterly revenue growth of 21% and data-center growth of 78%. Intel’s guidance disappointed investors, and the company expected a 20% drop in fourth-quarter PC sales. ¹⁰¹¹¹²
Smartphone weakness weighed on Qualcomm and Arm: Qualcomm shares fell as handset chip revenue dropped 26%, while Arm shares slid 9% as royalties grew 8%. Qualcomm targeted $5 billion in fiscal 2027 data-center revenue; Arm posted quarterly revenue of $1.44 billion. ^1314151617
Kioxia reported record first-half profit on AI-driven memory demand, with revenue of ¥4,247.2 billion and attributable profit of ¥2,197.9 billion. Its shares tumbled after December-quarter operating profit guidance fell below analyst estimates, raising concerns about slowing demand growth. ¹⁸¹⁹
Elsewhere, ASML raised its 2026 revenue forecast to €44 billion–€45 billion; Micron paused a $4.5 billion Taiwan plant over a labor dispute; Lam approved a $25 billion buyback; Astera Labs forecast $730 million–$750 million in fourth-quarter revenue; Synopsys planned 2,000 job cuts following its Ansys deal. ^2021222324
