Qualcomm’s Q4 Test: Can Diversification Offset the Smartphone Slump?

Qualcomm goes into its fiscal fourth-quarter report with a problem that is easy to describe and harder to solve: the legacy business is shrinking at exactly the moment the company is trying to prove that its next businesses can become large enough to replace it. Wall Street expects revenue of roughly $10.12 billion and adjusted earnings of $2.16 a share, versus $11.27 billion and $3.00 a share a year earlier. That implies a revenue decline of about 10% and an EPS decline of roughly 28%, so the market is already prepared for a weak headline quarter.

The more important issue is what Qualcomm says about the next several quarters. The company has spent 2026 pushing deeper into automotive, PCs, industrial edge computing, networking and data centers, while its latest agreements with Amazon and SpaceX give investors concrete examples of where the diversification strategy can lead. Those deals are strategically significant, but they do not yet erase the fact that smartphones remain the largest source of QCT revenue and that the current handset cycle is being hit by a severe memory shortage.

Qualcomm’s stock has already absorbed a large part of that concern. Shares closed at $164.43 on November 3 after falling 11.1% on October 30, leaving the stock well below its October 29 close of $185.41. The market is therefore less interested in whether Qualcomm beats $2.16 by a few cents than in whether management can make the transition from handset supplier to broader compute and connectivity platform look financially credible.

The Smartphone Downturn Is Bigger Than a Normal Cycle

The pressure on Qualcomm’s handset business is not simply another weak Android quarter. Counterpoint Research estimates that global smartphone SoC shipments fell 21% year over year in the third quarter, with rising memory costs, longer replacement cycles and cautious inventory management all contributing to the decline. The research firm expects smartphone SoC shipments to fall about 20% for full-year 2026 and another 3% to 4% in 2027, while memory prices are expected to rise again in the fourth quarter.

That backdrop explains why Qualcomm’s Q4 forecast is so heavily skewed toward handsets. QCT revenue is expected to fall about 10% to $8.8 billion, while handset revenue is expected to fall 24% to roughly $5.3 billion. Automotive is expected to hold up much better, with analysts looking for approximately $1.7 billion of revenue, but the arithmetic is important: a business producing several billion dollars of handset revenue cannot be replaced overnight by smaller adjacent markets.

Qualcomm also has a specific competitive issue inside Android. Counterpoint notes that Samsung is using a mix of Qualcomm’s Snapdragon 8 Elite Gen 5 and its own Exynos 2600 in the Galaxy S26 series. Chinese smartphone demand is also softer. The premium Snapdragon portfolio remains relatively resilient, but that does not fully protect Qualcomm when total device volumes are contracting and OEMs are trying to control bill-of-materials costs.

The most interesting announcement arriving just before earnings is Qualcomm’s new agreement with SpaceX. SpaceX selected Qualcomm’s Dragonwing Cellular Infrastructure platforms for Starlink Mobile’s planned nationwide terrestrial 5G network, with deployment expected to begin in 2027 and tens of thousands of sites planned over the multi-year agreement. Qualcomm says the platforms will supply Massive MIMO radio and baseband technology as well as Layer 1 software for the network.

This matters because it puts Qualcomm’s infrastructure business directly inside one of the most ambitious telecom build-outs underway. SpaceX is attempting to combine satellite connectivity with a terrestrial network and compete for traffic in a market dominated by AT&T, Verizon and T-Mobile. Qualcomm’s role gives it exposure to that build-out at the equipment layer, including radio processing and baseband infrastructure.

The financial contribution is still unknown because the companies did not disclose terms. It would be a mistake to capitalize the announcement as if it were already a multibillion-dollar revenue stream. The significance is strategic: Qualcomm has demonstrated that its connectivity and low-power compute expertise can travel from phones into carrier infrastructure, and SpaceX gives the company a potentially large deployment program beginning in 2027.

Amazon Is the Bigger Test of the AI Thesis

Qualcomm’s September agreement with Amazon is potentially more important to the long-term investment case because it moves the company into customized silicon for hyperscale AI infrastructure. The multi-generation collaboration covers custom chips for AWS AI inference as well as optical connectivity solutions supporting data-center networks at up to 1.6T and future generations.

The opportunity is large, but so is the competitive field. Qualcomm is competing for workloads that can otherwise be served by custom silicon developed internally by hyperscalers or by established data-center chip suppliers. Custom silicon can also carry different economics from Qualcomm’s traditional mobile business. The company therefore needs to demonstrate not just that it can win design slots, but that those wins can generate attractive margins and recurring volume.

That is why Qualcomm’s fiscal 2027 outlook matters more than a single Q4 beat. Management has said non-handset sales, including data center, could grow more than 60% in 2027. At Investor Day, Qualcomm set a target of more than $15 billion in data-center revenue by fiscal 2029 and $40 billion in total non-handset QCT revenue. Those targets are ambitious enough to change the company’s valuation if execution starts showing up in reported revenue rather than presentations.

Qualcomm’s fiscal 2029 targets make clear how much scale management expects from the new businesses: $40 billion of non-handset QCT revenue, including $10 billion from automotive and more than $14 billion from IoT, while the broader data-center strategy targets more than $15 billion. The automotive design-win pipeline has also been raised to $65 billion. These numbers are not forecasts for next year; they describe the size Qualcomm believes the businesses can reach over several years.

The timing gap is the central risk. The smartphone decline is happening now, while much of the diversification payoff is back-loaded. SpaceX’s terrestrial network rollout begins in 2027. Amazon’s collaboration is multi-generational. BlueChip, the Qualcomm-Anduril effort to rebuild U.S. computer manufacturing around Snapdragon X, plans to begin taking laptop orders in 2027. Qualcomm therefore has a bridge period in which the old engine is shrinking before the new engines are large enough to carry the company.

That bridge is where tonight’s guidance will matter. If management points to stronger automotive, IoT and data-center orders but also indicates that handset weakness will persist, investors may continue to treat Qualcomm as a transition story. If it can show that the non-handset businesses are accelerating quickly enough to offset the decline, the stock could begin trading on a different earnings base.

Memory Is the Wild Card Investors Cannot Ignore

The memory shortage complicates the picture because it affects Qualcomm indirectly. Qualcomm does not sell the DRAM and NAND chips causing the bottleneck, but smartphone OEMs cannot ship complete devices when memory is scarce or prohibitively expensive. Counterpoint says global smartphone SoC shipments fell 21% in Q3 and expects memory prices to rise another 5% quarter over quarter in Q4. That makes Qualcomm’s customers more cautious about inventory and product launches even when demand for premium devices remains comparatively healthy.

The industry response is already visible. Apple has warned that unprecedented memory costs will pressure margins, while Intel and AMD have also pointed to weaker PC demand. For Qualcomm, the risk is that OEMs respond to higher memory costs by reducing lower-end models, delaying purchases or concentrating volume in fewer premium configurations. Some of those moves can protect Qualcomm’s premium Snapdragon business, but they do not eliminate the volume hit.

Management’s commentary on memory allocation may therefore be one of the most valuable parts of the call. Investors need to know whether Qualcomm sees the problem as a temporary inventory shock, a longer 2026-27 downturn, or a structural change in device economics.

The Q4 print itself is likely to be the least interesting part of Qualcomm’s report. A modest EPS beat would not change the investment case if management guides cautiously for handsets and pushes the major diversification benefits further into the future. Conversely, a revenue miss could be absorbed if Qualcomm shows that data center, automotive and infrastructure orders are accelerating enough to change the trajectory of 2027.

The key numbers to watch are handset revenue and QCT margins first, followed by automotive and IoT growth, the timing of data-center revenue and any additional detail on the Amazon relationship. Investors should also listen for the effect of memory shortages on customer ordering patterns. Qualcomm has already laid out a credible roadmap for becoming less dependent on smartphones; the question now is whether the new businesses can grow quickly enough to matter before the old business becomes a serious drag.

That is why the SpaceX announcement is useful context for this earnings report. It does not fix the handset downturn, and it does not make the data-center business an overnight success. It does, however, show the kind of customer Qualcomm needs more of: large, infrastructure-heavy platforms where its connectivity, processing and power-efficiency expertise can be sold outside the smartphone bill of materials. If Qualcomm can turn those wins into recurring revenue over the next two years, the current earnings weakness may look like the trough of a transition rather than the beginning of a longer decline.
