Apple’s revenue growth remains strong; cost pressures and AI returns need separate assessments

Revenue growth has clear drivers, but performance varies across businesses

Apple’s quarterly revenue was $114.477 billion, including $57.583 billion from iPhone, which contributed 71.25% of the company’s revenue increase. Mac revenue grew 23.68% and Services revenue rose 9.82%, while iPad and Wearables, Home and Accessories revenue declined 10.40% and 7.91%, respectively. These results support the judgment that Apple still has strong revenue growth from its core products, but its businesses are not expanding in step. iPhone revenue reflects unit sales, prices and product mix. Revenue growth alone cannot establish the strength of replacement demand, nor can that growth be directly extrapolated to subsequent quarters.

Signs of profit pressure have emerged; its future extent remains uncertain

Quarterly revenue grew 12% year over year, operating expenses rose 20.58% and operating profit increased 9.88%. For this quarter’s operating profit, expense expansion affected how efficiently revenue growth translated into profit growth. This comparison cannot be generalized to net income or full-year performance. The overall gross margin of 47.9% also included a favorable impact of about 1 percentage point from tariff refunds, so the reported margin cannot simply be treated as a sustainable operating level. The annual report separately disclosed supply constraints and rising costs for advanced semiconductors, memory and storage, and forecast intensifying pressure on memory and storage. Current pressures should be distinguished from the company’s expectations for the future; the latter have yet to materialize.

What the increase in purchase obligations tells us

Manufacturing purchase obligations rose from $57 billion on June 27 to $89.7 billion on September 26, an increase of $32.7 billion in the outstanding balance. This shows that Apple took on more future manufacturing purchase obligations. My judgment is that this makes future supply arrangements an operating variable worth watching, but the balance change alone cannot establish that supply has been secured. It is also not cash spending for the quarter and cannot be attributed entirely to rising storage prices or demand for Siri AI. The annual report also cautions that price increases may not fully offset costs and could depress demand, so their effects must be assessed against actual sales and gross margin performance.

Services gross profit provides support, but does not directly represent AI profitability

Services accounted for 27.58% of quarterly revenue and contributed 43.74% of gross profit. Its gross margin was 75.95%, above the 37.20% margin for products. This supports the inference that Services provides important support for Apple in absorbing fluctuations in hardware costs. However, gross profit does not deduct all research and development and selling, general and administrative expenses. This share therefore cannot be treated as Services’ contribution to operating profit, much less attributed to AI. Full-year research and development expenses were $45.765 billion, up 32% year over year. The company attributed the increase mainly to infrastructure-related expenses, including AI investment, and employee expenses. This supports the judgment that investment is expanding, but does not yet allow Siri AI’s costs and returns within that spending to be quantified.

Siri AI’s accounting treatment is clearer; incremental business gains remain unproven

The annual report includes Siri AI among the performance obligations for services bundled with certain devices. Device sales revenue is allocated based on relative standalone selling prices, with the services portion deferred and recognized on a straight-line basis over the expected service period. This means the relevant services can receive an allocation of revenue from the device’s selling price; it does not establish that they generate additional paid revenue. A single period’s disclosure also cannot establish that the policy was newly introduced. The more cautious judgment at this stage is therefore that Apple’s core products can still drive revenue, while rising costs and expanding research and development spending raise the bar for translating growth into profit. Only if subsequent disclosures demonstrate measurable incremental revenue or demand from AI, alongside easing procurement pressures, will there be grounds for a more favorable assessment of the quality of growth.

What to watch next

• Whether subsequent gross margin disclosures show easing cost pressure on key components and distinguish special effects such as tariff refunds.
• How manufacturing purchase obligations, actual payments and deliveries change, and whether clearer evidence of improved supply emerges.
• Whether Apple discloses information that identifies incremental AI revenue, usage demand or returns on investment, beyond the accounting allocation of bundled revenue.
• Whether the relationship between operating expense growth and operating profit growth improves, and whether price increases are accompanied by weaker demand.
