Apple's Inventory Jumps 154% as Memory Chip Costs Bite

Apple's inventory swelled 154.3% year-over-year to $14.54 billion in its fiscal fourth quarter, a figure that tells you exactly where the memory chip cost squeeze is heading. The stockpile grew from $11.09 billion in Q3 to $14.54 billion in Q4 — a 31.1% jump in a single quarter, up from $5.72 billion in the year-ago period, according to earnings reported Monday.

The company guided its December-quarter gross margin down to 45% to 46%, largely because of higher memory costs. That compares with a 47.9% gross margin in the September quarter — a drop of roughly two to three percentage points, meaningful slippage for a hardware business of Apple's scale.

What does the memory spike actually change for Apple?

CEO John Ternus didn't mince words on the analyst call. "What we're seeing with memory pricing right now is unprecedented," he said.

He walked through the mechanics. "As we said earlier in the September quarter, we did see higher memory costs as compared to the June quarter, which were partly offset by the benefit of carrying inventory and lower costs on certain non-memory components."

The buffer, in other words, is the inventory itself. Apple bought memory ahead of price increases, and that carry-in stock softened the blow in September. That cushion will thin out.

Ternus said the company expects "even higher memory costs" in the December quarter. The offset this time: price increases Apple already implemented earlier this year — Mac and iPad at the end of June, and iPhones in September. Beyond December, he expects memory costs "continuing to increase."

A $33 billion commitment to lock in supply

Here's the number supply chain watchers should circle. "As we work to improve supply, our manufacturing purchase obligations have increased by 33 billion dollars from June to the September quarter, which you'll see in our annual filing when it comes out tomorrow," Ternus said.

That's a $33 billion escalation in committed purchases in one quarter. It signals Apple is willing to pay up front to secure memory allocation rather than gamble on spot pricing.

Apple also put COO Sabih Khan, who oversees the company's supply chain and manufacturing, on the call to field memory questions. He reiterated the increased purchase obligations. Notably, he did not rule out future price increases on Apple devices — a signal worth reading closely if you track Apple's pricing strategy.

"As we said before, we do believe we'll see a decreasing benefit from the carry-in inventory on memory over time," Ternus noted, confirming the stockpiling advantage is temporary by design.

iPad takes the hit while iPhone and Mac deliver

Apple blamed supply constraints for weak iPad sales in the quarter. iPad revenue came in at $6.2 billion, below analysts' expectations of $6.7 billion and down 10% from the prior year. It was one of the only product segments that didn't grow, even as iPhone and Mac sales beat estimates.

The divergence matters. Memory constraints aren't hitting Apple's product lines evenly — the iPad absorbed the shortage while the flagship categories held up.

For practitioners, the takeaway is straightforward: Apple is trading cash for supply security, margins will compress through at least the December quarter, and the door to further device price increases stays open. Watch the annual filing for the full picture of those purchase obligations — and watch whether memory prices keep climbing into next year, because Apple has already told you it expects them to.
