    Western Digital and Astera Labs Model Over 125 Percent Q3 EPS Growth on AI Demand

    Question

    Western Digital and Astera Labs Model Over 125 Percent Q3 EPS Growth on AI Demand

    Direct answer

    Data center hardware suppliers Western Digital (WDC) and Astera Labs (ALAB) reflect expanding demand across cloud storage and high-speed semiconductor connectivity. Western Digital gained 1.01% to outpace the S&P 500, with Q3 consensus estimates projecting EPS of $4.07 (+128.65% YoY) on $4.16 billion in revenue (+47.45% YoY). Astera Labs dipped 1.39% to $342.21 but maintains a 21.97% gain year-to-date. Consensus forecasts for ALAB's November 3 release anticipate EPS of $1.19 (+142.86% YoY). The triple-digit earnings trajectories highlight tight supply conditions in high-bandwidth memory and interconnect infrastructure. — bullish pressure on WDC.
