Apple Stock’s Biggest Risk Is The Memory Bill, Not Demand

Record demand is not the danger for Apple stock; the danger is a component bill that keeps climbing and has already begun to take margin down.

Apple (AAPL) has just posted a June quarter revenue record in every geographic segment it reports, and its stock has outperformed the S&P 500 over the past year. That is not where the risk sits. The biggest threat to Apple stock now is a cost line that has already pulled margin down once, is guided to pull it down again, and whose end management cannot yet see: memory.

Ex-Refund Gross Margin Has Stepped Down On Memory, And Is Guided Down Again

Reported gross margin in the June quarter was 50.1%, but roughly two percentage points of that came from tariff refunds. Strip those out and Apple earned 48.1%, down from 49.3% in the March quarter, and by the CFO’s own account more than all of that step down was memory cost rather than currency. The September quarter guide takes margin lower again, to a 46.5% midpoint before refunds, and again, memory accounts for more than the entire decline.

Memory sits in the bill of materials across iPhone, iPad, and Mac, and by management’s own account, the DRAM market has three suppliers; a wider supplier base would help supply, though management calls the price effect unclear. Apple has already raised prices on iPad and Mac, reluctantly by its own description, to cover what it calls exponential increases in memory prices. Holding margins through a cost shock like this one is the sort of durability the Trefis High Quality Portfolio insists on in its holdings, and Apple’s September quarter guide points the other way.

The China Memory Workaround Would Fix Supply, Not The Bill

Press reports say Apple has been testing memory chips from China’s CXMT for iPhones and MacBooks to mitigate a component shortage fueled by the AI boom and that using them in devices sold in China would need White House approval under U.S. restrictions. That would fix availability, not the bill. Apple’s cushions are limited: management expects the carry-in inventory benefit to decrease beyond the September quarter, and says memory pricing keeps climbing from there.

The Price Is What Turns A Cost Line Into A Risk

None of this is a demand problem. June quarter revenue was $109.4 billion, up 16%, with iPhone up 22% and Mac up 29% on the strength of MacBook Neo and MacBook Pro. The 9% to 11% growth guided for the September quarter reflects a currency headwind and a supply cap on the advanced nodes Apple’s chips are made on, not a crack in demand. The risk is what you are paying for that demand. The stock trades at 9.6 times sales, about 100% of the way up its own decade-long range, while net margin of 27.6% is the highest in at least five years and above its three-year average of 25.8%. A peak margin bought at a peak multiple leaves no room for the memory bill to run further than management expects.

What settles this is the September quarter gross margin excluding tariff refunds against the 46.5% midpoint management guided. Meanwhile, the market is treating the wait as routine: implied volatility sits at 23, the 50th percentile of its own past-year range, so the size of move the options market is currently pricing is ordinary for a stock whose worst peak-to-trough fall in the past year was 13.8%.

One Component Bill Should Not Decide Your Year

Owning Apple here means accepting that one input price, set by a market the company does not control, can move the margin its valuation rests on. Spreading that exposure is the case for a rules-based basket such as the Trefis High Quality Portfolio. That portfolio has a track record of outpacing the three major indices – the S&P 500, S&P Mid-cap, and Russell 2000.
