Qualcomm Stock Sank 11% This Week on Weak Guidance. Here’s the Path Forward
Qualcomm’s (QCOM) fiscal Q3 results met expectations, with GAAP EPS of $1.87 on revenue near $9.95B. The stock fell about 11% after fiscal Q4 adjusted EPS guidance of $2.05 to $2.25 missed analysts’ ~$2.36 model. Management cited higher memory/component costs and faster-than-expected Apple modem revenue decline. The article also notes Modular acquisition and a BMW deal.
How this was made

The 30-second read
Why it matters
The immediate trading driver is the adjusted EPS outlook range below analyst expectations, with management pointing to higher memory/component costs and faster Apple-related revenue erosion. Longer-term support comes from non-handset expansion via the Modular acquisition, a BMW compute-chip supply deal, and a raised 2029 non-handset revenue target.
Market read
Traders are likely to focus on whether the cited custom silicon revenue timing in the December quarter offsets the Apple-related decline and margin pressure.
What to watch
The article emphasizes cost pressures and Apple modem erosion, but does not quantify how much of the guidance gap is timing versus structural margin deterioration, which could change the magnitude of the re-rating.
Background
The piece follows Qualcomm’s fiscal third-quarter results that were near consensus, but focuses on weaker-than-expected fiscal fourth-quarter guidance.
Ticker impact
Qualcomm shares fell about 11% after fiscal Q4 adjusted EPS guidance of $2.05 to $2.25 missed the ~$2.36 analyst model.
Bias toward continued volatility until December-quarter custom silicon revenue timing and Apple-related revenue stabilization become clearer.
The article attributes the selloff specifically to next-quarter guidance below consensus, then frames two offsetting positives (Modular acquisition, BMW compute deal) that are longer-dated and execution-dependent.
Market effects
Reinforces that handset exposure and modem share dynamics remain a key valuation swing factor for semiconductor names with mobile revenue mix.
Primarily US large-cap semiconductor sentiment spillover; no specific regional catalyst beyond QCOM’s guidance reaction.
Highlights ongoing global AI compute and automotive chip demand, but with near-term risk tied to Apple-related revenue trends.
Counterpoint
If custom silicon programs start generating revenue on schedule in the December quarter, the guidance miss may prove temporary and the market may re-rate toward the non-handset growth path.
