Apple Forecasts Lower Margins Amid Rising Memory Prices and AI Costs

Apple is warning that soaring memory-chip prices could squeeze iPhone profitability during the holiday quarter, even as demand for its premium smartphones drives record sales.

In its November 2 earnings release, Apple reported $114.5 billion in quarterly revenue, up 12% year over year, and a 47.9% gross margin. However, management expects that margin to fall to 45%–46% in the December quarter as memory costs and AI infrastructure expenses rise.

The warning adds another challenge to the latest Apple stock earnings outlook, which has left investors weighing resilient iPhone demand against deteriorating hardware economics.

Apple's newly filed 2026 annual report reveals how aggressively the company is securing manufacturing capacity.

Its manufacturing purchase obligations reached $89.7 billion as of September 26, including $82.7 billion payable within 12 months. The total increased approximately $33 billion from the previous quarter.

Meanwhile, inventory climbed to $14.54 billion from $5.72 billion a year earlier, an increase of roughly 154%.

Components accounted for $10.45 billion of the inventory balance, up from $2.12 billion in September 2025.

These figures do not represent memory purchases alone. However, they demonstrate the scale of Apple's broader response to increasingly constrained component supplies.

CEO John Ternus described the memory-pricing environment as unprecedented during Monday's earnings call.

Apple has benefited from components acquired at lower historical prices, but management expects that protection to diminish as new purchases reflect higher market rates.

Earlier iPhone production concerns already highlighted the challenge of balancing higher component costs against consumer demand.

Artificial intelligence infrastructure requires enormous quantities of advanced memory, drawing manufacturers toward high-margin data-center products.

That demand can tighten availability of conventional memory used in smartphones and personal computers, even though high-bandwidth AI memory and smartphone DRAM are not interchangeable.

The supply pressure has helped companies such as Samsung, whose AI memory business reported extraordinary profit growth.

For Apple, the same trend threatens manufacturing costs.

The company has already raised prices on several products, including premium iPhones and MacBooks, to offset component inflation.

However, further increases could weaken demand if consumers resist paying more for new devices.

The challenge also complicates Apple's premium stock valuation, which depends partly on sustaining high profitability across its hardware ecosystem.

Apple's September-quarter iPhone revenue reached approximately $57.58 billion, exceeding analysts' $56.54 billion estimate.

Demand for the iPhone 18 Pro remained strong, while the new foldable iPhone Duo attracted significant early interest.

Yet Apple's 47.9% company-wide margin included roughly one percentage point of benefit from tariff refunds, making the underlying profitability comparison less favorable.

The December forecast also reflects costs associated with expanding AI-powered Siri.

Apple expects quarterly revenue growth of 7%–10%, suggesting demand remains healthy despite the pressure.

The key question for AAPL investors is whether higher selling prices and product growth can compensate for rising component expenses.

Apple's earlier AI-related supply constraints demonstrate that this challenge has been building for months.
