Qualcomm, Arm Shares Slide as Smartphone Slump Bites
Qualcomm and Arm reported weaker-than-expected results due to a smartphone market slump caused by a memory supply crunch. Qualcomm's Q4 revenue fell 8% YoY to $10.32B, beating estimates, while Arm's Q2 revenue rose 27% YoY to $1.44B, also beating estimates. Both companies are expanding into AI data center chips but remain exposed to smartphone downturns. Shares of both companies fell post-earnings.

The 30-second read
Why it matters
Earnings miss and guidance shortfall highlight the vulnerability of mobile‑chip revenue to supply‑chain constraints, prompting immediate share declines.
Market read
Both stocks fell sharply on earnings and guidance, signaling sector pressure and potential re‑rating of mobile‑chip exposure.
What to watch
Both firms' expanding data‑center AI chip businesses may provide a longer‑term growth runway not reflected in the short‑term price move.
Background
Qualcomm and Arm dominate mobile chip architecture; both are now expanding into AI data‑center chips but remain exposed to smartphone demand cycles.
Ticker impact
Qualcomm reported Q4 revenue down 8% YoY and missed smartphone demand expectations, causing a 6.5% after‑hours drop.
downward pressure as investors price in lower handset chip demand and stagnant smartphone market outlook
Revenue fell short of consensus, handset chip sales dropped 26%, and guidance signals continued stagnation, all new primary disclosures.
Arm posted Q2 FY27 revenue up 27% but guidance of $1.54B fell short of some expectations, leading to a 5.3% share decline.
downward as the market digests weaker-than‑expected revenue guidance amid smartphone slowdown
Guidance is a fresh primary fact; the shortfall relative to some broker forecasts drives immediate price pressure.
Market effects
Smartphone chip segment faces headwinds, potentially dragging other handset‑related suppliers.
Asia‑Pacific chip makers may see valuation pressure as China handset demand stalls.
Broader semiconductor sector could see modest pullback amid concerns over memory‑supply constraints.
Counterpoint
If memory‑supply issues ease, AI‑related revenue growth could offset handset weakness, offering upside.
