Apple's fiscal fourth quarter, reported Nov. 2, beat on the top line and warned on the bottom line. Revenue reached $114.5 billion, up 12%, and earnings per share of $2.10 exceeded estimates. Guidance for the December quarter called for gross margin of 45% to 46%, down from 47.9%, and management attributed most of the decline to memory.
The procurement number is the real story. Apple's manufacturing purchase obligations rose $33 billion between the June and September quarters, reaching $89.7 billion, according to the annual filing. About $82.7 billion falls due within a year. Commitments due beyond twelve months rose to $7 billion from $0.8 billion in June. The total surpassed the previous September high of $71.1 billion set in 2022 and represented roughly 132 days of manufacturing cost, against a historical average near 100 days and a 2022 peak of 137.
Chief executive John Ternus called current memory pricing unprecedented three times on the call and said prices would keep rising beyond the December quarter. Chief operating officer Sabih Khan said memory would constrain Mac and iPad supply in the holiday quarter because demand ran ahead of expectations. Component inventory reached $10.4 billion from $2.1 billion a year earlier, and total inventory reached $14.5 billion, up 154%.
Chief financial officer Kevan Parekh said higher memory costs drove roughly a one-point change in gross margin between quarters, with the September figure also carrying about a point of benefit from tariff refunds.
Why the most powerful buyer in consumer hardware had to relearn how to buy is a supply story with an AI cause. Investment in accelerators and the data centers that host them pushed memory prices up by as much as 400% over two years, according to reporting by Supply Chain Dive. TrendForce forecast on Sept. 30 that conventional DRAM contract prices would rise 10% to 15% in the fourth quarter and NAND flash 15% to 20%, as manufacturers allocate wafer capacity to server memory and high-bandwidth products.
IDC research director Phil Solis described the mechanic directly: every company buying memory has had to change how it buys if it wants stable pricing and guaranteed supply, and scarcity has given memory suppliers the upper hand for now. Longer agreements replace the short-dated arrangements that worked when supply was plentiful. Apple had spent years avoiding exactly that, using its scale to buy what it needed when it needed it, and the change is a measure of how far the market has moved.
The cost of that shift is optionality. Apple's annual report warns that it may not fully utilize purchase commitments if demand or production needs change, and that it records reserves for cancellation fees on excess orders. A commitment book worth 132 days of production is a bet on volume, placed at a moment when the company is also raising prices: Mac and iPad at the end of June, iPhone in September.
Peers are running the same play with less leverage. HP said in February it was securing long-term agreements to cover its fiscal 2026 memory needs, with memory and storage at roughly 35% of a personal computer bill of materials. In its latest quarter HP's PC shipments fell 16% while PC revenue rose 18%, a price-for-volume trade that preserves revenue at the cost of units. For smaller assemblers and contract manufacturers, the message is harsher: scarce allocation goes to whoever can commit first and longest, and the bid is made months before the invoice.
There is a partial offset on the logic side. Apple expects relief in system-on-chip supply as it moves to a more advanced 2-nanometer process, because AI servers still run on 3-nanometer technology and are consuming that capacity. Solis noted the reprieve lasts only until server silicon migrates to 2nm.
Forecasts on duration diverge, which is itself informative. Bernstein expects DRAM prices to rise about 43% through 2027 and then fall sharply in 2028, though from a level still above the pre-crisis baseline. The chief executive of memory module maker Team Group said the shortage would be tightest through the second quarter of 2027, with balance unlikely before the second half of 2028. Both are projections rather than disclosures, and both imply that the current quarter is not the peak of the cost curve.
The practical lesson for procurement teams is that memory has become a contracted commodity again, and terms are set by whoever signs longest. That argues for three changes. Shorten quote validity on any bill of materials containing DRAM or NAND, because a ninety-day price hold is now an exposure rather than a courtesy. Secure allocation before committing delivery dates to customers, since a missed date costs more than a higher unit price. And treat inventory as a hedge with a carrying cost rather than as evidence of inefficiency, which is what Apple is doing at a scale few can match.
Apple's $89.7 billion is not a demand forecast. It is the price of certainty in a market where the supplier, for the first time in years, sets the calendar.
