How Much Of Qualcomm Stock Rides On One Business

Phone chip revenue is the central metric to watch at Qualcomm (QCOM). Handset chips generated $5.1 billion in fiscal Q3 2026, accounting for more than half of the company's $9.9 billion in revenue. Total revenue fell 4.0% from a year earlier, and a segment that makes up more than half of sales deserves close attention. So what is hurting Qualcomm's phone chip sales?

Qualcomm Faces Costlier Memory And Less Apple Business

Qualcomm management detailed two causes on its fiscal Q3 2026 call. The memory chip market presents the first hurdle. Management said memory conditions across the global smartphone market affected handset revenue. CNBC reported on September 22, 2026 that the smartphone industry is contracting because of skyrocketing memory prices. Alongside these broader conditions, management said revenue from Android phone chips dropped 20% from a year earlier.

The second issue centers on Apple. Qualcomm said on its July earnings call that it expected its share of the upcoming iPhone launch to be materially lower than its earlier estimate of 20%. The company also expected Apple revenue to drop faster starting in fiscal Q4 2026.

This slowdown is already visible in Qualcomm's total revenue. After growing 10.0% and then 5.0% in the first two of the last four quarters, revenue fell 3.5% and then 4.0% in the final two periods.

Reduced business from Apple also alters the seasonal shape of Qualcomm's year. The fiscal first quarter was traditionally the strongest period. Management told investors not to expect that pattern now, as Apple's strong December quarter is missing from the current forecast.

Can Qualcomm Make Up For Weaker Phone Chips?

Management asserts it can bridge the gap, yet the answer relies heavily on forecasts. The company has reported growth outside of phones thus far. Chip sales outside handsets, which include automotive and connected devices, grew 28% from a year earlier in fiscal Q3 2026. Automotive revenue alone hit $1.6 billion, up 61%. Within the phone segment itself, management estimates that chip sales to Chinese phone makers reached a bottom in fiscal Q3.

Qualcomm has not yet proven that this growth can replace Apple. Management expects growth outside handsets in fiscal 2027 to replace the Apple revenue of fiscal 2026. That fiscal 2027 forecast includes data center revenue growing to $5 billion in a market Qualcomm is entering now. Management acknowledged that investors want more proof it can deliver there as a new entrant.

Is Qualcomm Stock Already Priced For Trouble?

The market appears to have priced in some of this weakness. Qualcomm stock trades at 19.9 times earnings, compared to 21.9 for the S&P 500. The stock returned 7.5% over the past twelve months, while the index returned 17.3%. Measured on earnings, the stock trades at a modest discount to the index, so the market has priced in only part of the phone chip weakness.

Investors determining position sizes should study how Qualcomm stock has behaved in market selloffs. The shares fell 41% during the 2022 inflation shock, against a 24% drop for the S&P 500. During the 2025 tariff shock, the shares fell 28%.

Shareholders have reason to worry about phone chips, though in proportion: the stock already trades below the index's P/E, and businesses outside phones are growing. Management forecast approximately $5.2 billion of handset chip revenue for fiscal Q4 2026, slightly above the $5.1 billion of fiscal Q3. The company expected Android chip sales to grow from the prior quarter and Apple revenue to fall. Handset chip revenue, weighed against that forecast, remains the crucial number to watch in Qualcomm's fiscal Q4 2026 report.

Does This Mean You Should Act On QCOM?

Our purpose is to inform you with unique data so you make the right investment decisions. That said, betting on a single stock is always risky, no matter which direction you choose.

There is a smarter approach. Since its inception, the Trefis High Quality (HQ) Portfolio has returned 105%, beating the benchmark that combines the three major indices - the S&P 500, S&P Mid-cap, and Russell 2000. And it did so without taking the concentrated risk that comes with do-it-yourself stock picking. If that is how you want to invest, the HQ Portfolio is the place to start.
