Qualcomm beat both revenue and earnings estimates for its fiscal fourth quarter, yet the stock fell nearly 10 percent on Thursday after an intraday slide of almost 14 percent. The market ignored the headline upside, $10.4 billion in revenue versus $10.1 billion expected, and $2.17 per share against a $2.16 consensus, and priced the deterioration underneath instead. Handset revenue dropped 26 percent to $5.1 billion, and pretax earnings in that segment fell 30 percent. The chipmaker also guided fiscal first-quarter revenue of $10.4 billion to $11.2 billion, well below the $12.3 billion it recorded a year earlier, and forecast earnings of $2.15 to $2.35 per share against a Street estimate of $2.32.

The handset drag is structural

The mobile business that once defined Qualcomm is shrinking fast. Handset revenue fell $3.7 billion over the past year as the Apple relationship narrows and the broader smartphone market stalls. Memory costs are rising, compressing margins further. The company earned $2.78 per share in the year-ago quarter on $12.3 billion of revenue; the new midpoint implies a 20 percent profit decline on 15 percent less sales. Investors are not rewarding the beat because the quality of earnings has shifted from volume leverage to cost absorption.

Data center narrative carries a 2027 price tag

Management is pointing to fiscal 2027 as the inflection year. Chief Executive Cristiano Amon said non-handset revenue will grow more than 60 percent year over year by then, and reiterated a $5 billion data center revenue target. That would represent roughly 13 percent of the $37.2 billion the company just booked for fiscal 2026. Meta is a confirmed customer, but the ramp starts from zero. Morgan Stanley flagged the risk bluntly: conviction is low on a three-year buildout in a target-rich AI semiconductor environment, and it is unclear whether a custom-chip foundation has legs if AI demand softens.

Valuation cheap only if earnings hold

The stock trades at about 15 times the projected $10.16 per share for the current fiscal year. That multiple looks reasonable only if the handset trough is behind the company and the data center ramp materializes on schedule. Neither is assured. The guidance cut, the segment margin collapse, and the three-year horizon for a new growth engine leave the beat feeling like a distraction. The market priced the transition, not the quarter.
