Executive Summary
DRAM prices have doubled to tripled over the past quarter, creating a 200 basis point gross margin headwind for Cisco next quarter that represents a structural shift rather than temporary disruption. Wu Junho, Bloomberg's senior hardware networking analyst, confirms this affects the entire hardware ecosystem - Dell, HPE, and any DRAM-heavy server manufacturers face identical pressures. Memory manufacturers, burned by COVID overcapacity, remain hesitant to build new fabs despite AI-driven demand exceeding all forecasts. The supply constraint timeline extends through 2027-2028, with hard disk drive manufacturers already sold out through 2026-2027 and taking orders for 2028. Cisco's 10.5% post-earnings decline reflects multiple compression from 21-22x PE back to historical 17-18x range, despite consistent earnings beats and AI infrastructure tailwinds. The market is pricing perfection incorrectly - this is an industry-wide input cost shock, not Cisco execution failure. Management will pass through price increases across product lines, but margin compression persists until supply capacity additions come online in 2027-2028. Meanwhile, AppLovin's 19% decline on AI disruption fears highlights how memory constraints create winners and losers - mobile advertising platforms with established data moats remain defensible, while hardware companies face unavoidable input cost inflation regardless of demand strength.
Key Insights
what Wu Junho said“every time you have, if you want to create capacity for new memory chips, it takes about 2 to 3 years. And the memory manufacturers were struggling very badly during the COVID period when there was over capacity. And they've been hesitant to build up the capacity.”
