The setup
Apple bought its way through the memory shortage, and the bill has not finished arriving: our call is that December-quarter gross margin prints at or below 46.0%, the top of the 45–46% guide, and that operating income comes in no higher than the $50.85B of a year ago even with revenue guided up 7% to 10%. A gross margin above 46.5%, or operating income above $52.34B, the top of the guide's own arithmetic, refutes it. The evidence is on the balance sheet, not the income statement. Inventories ended September at $14.54B against $5.72B a year earlier, components were $10.45B of that against $2.12B, and the company's manufacturing purchase obligations rose $32.7B in a single quarter to $89.7B.
Apple reported its fiscal fourth quarter on , the first report under chief executive John Ternus. Net sales were $114.48B, up 11.72% on the year and a September-quarter record. Products were $82.90B (+12.46%) and Services $31.57B (+9.82%). Gross margin was 47.89%, which the release says includes a favorable impact of about one percentage point from tariff refunds. Operating income was $35.63B (+9.88%), net income $30.71B (+11.81%), and diluted EPS $2.10, up 13.51%, of which $0.05 was tariff refunds. The full year was a record too: $478.83B of net sales (+15.06%) and $8.98 of diluted EPS. The stock traded at $332.40 at 10:23 PT on , down 1.75% from the $338.32 close.
The headline reads as a clean beat. The 10-K that landed the next morning reads as something else: a hardware company that spent the year turning cash into components. The inventory balance had sat between $5.72B and $7.29B in every quarter-end from through . It is now 2.00 times the top of that range. On cost of sales it is 22.2 days of goods, against 7.2 to 11.3 days in the six quarters before June. Apple does not hold inventory. This year it started to, and what it holds is the one input the memory makers reprice every quarter.
The December guide is where the two halves meet. Chief financial officer Kevan Parekh guided revenue up 7% to 10%, above the consensus figure cited in post-call coverage, and gross margin to 45% to 46%, below this quarter's 47.89% and below the 48.16% of the same quarter a year ago. Put the midpoints together and revenue of about $155.98B carries operating income of about $50.37B, 0.95% below last December's. Apple is guiding to its biggest quarter ever and to no operating profit growth in it. Memory is the reason it gave, and the stockpile is the reason it is not worse.

One piece of context before the argument. Tariff refunds ran through cost of sales in both the June and September quarters. The release puts the September benefit at about a point of gross margin and $0.05 of EPS, so the operating gross margin was about 46.9%, and Parekh said Apple has now "received the vast majority of the refunds related to tariffs paid." December carries none.
