Broadcom’s AI Boom Has A Memory Problem
Broadcom (AVGO) reported record Q3 revenue of $29.6B, up 86% YoY, with AI semiconductor revenue surging 221% to $16.7B. However, gross margins are expected to decline to 73% in Q4 due to increased memory requirements in AI chips, despite strong demand. The company's CFO and CEO noted that memory costs and supply chain constraints are impacting profitability and growth forecasts.
