Apple Inc. AAPL

Key data

The business

Apple sells the iPhone, Mac, iPad and wearables, and on top of that hardware runs a Services business: App Store commissions, iCloud, payments, the Google search default and subscriptions. The compounding is the attach. The moat is switching cost: iMessage, iCloud, purchased apps and an install base above two billion devices make leaving expensive, which is why Apple can raise Services prices and take a cut of nearly everything transacted on the phone. Concentration sits in distribution, not end demand. One customer was 18% of receivables owed to Apple at quarter-end and cellular carriers another 27%, so a stumble by the carriers shows up in Apple's collections before it shows in a headline.

The numbers

The story of the last year is reacceleration and margin arriving at the same time.

Revenue reaccelerated to the mid-teens across fiscal 2026, up 16% in the June quarter against a stretch when growth was roughly flat, with EPS ahead of consensus each quarter, the latest by 7%. Net income outran revenue, up 27% in Q3, because the company earned more on each dollar.

Zoom out and the machine is steadier than the recent pop suggests. From fiscal 2021 to 2025 revenue compounded just 3.3% a year while diluted EPS compounded 7.4%, the gap bought with margin and a share count down about 11% over four years. Earnings grow at roughly twice the top line. The fiscal 2026 quarters are the first in years where the top line itself is pulling its weight.

The margin ramp is the whole question. Gross margin climbed from 46.5% a year ago to 50.1% last quarter, its best in years. The catch is that the June quarter is seasonally light on iPhones, which flatters the mix, and the December quarter is product-heavy and is where a 50% number gets tested. The market prices Apple as a low-single-digit revenue compounder re-rated for services. The wager here is that mid-teens revenue growth and a 350 basis point margin lift are running together right now, and the print that settles it is whether the December quarter holds gross margin near 49% while revenue clears $150B.

Management

Insiders sold and never bought: 23 sales worth $115.6M over the past year, zero purchases, with chairman Arthur Levinson accounting for about $86.7M of it across May. The vendor feed does not carry the 10b5-1 status, so whether those were pre-scheduled or discretionary is not disclosed, and at this size relative to their holdings it reads as routine diversification rather than a signal. The louder capital story is the buyback. Apple spent $90.7B repurchasing stock in fiscal 2025 and $62.2B in the first nine months of 2026, retiring roughly 3% of shares a year, but it is buying at near-record valuation, 37 times trailing earnings and in the 92nd percentile of its twelve-year range. R&D jumped 33% year over year, a real step-up that reads as the AI bill coming due.

How it fails or surprises you

Margin gives it back. Q3's 50.1% gross margin is a peak struck in Apple's lightest iPhone quarter. If December's product-heavy mix drops it back toward the 46% to 47% of fiscal 2024, EPS growth halves and 37 times earnings has nothing underneath it. The first read is the gross-margin line in the Q1 report due late January, and anything under 49% starts the de-rate.

The China and search-payment tail. Greater China remains the swing region, and the roughly $20B annual Google search payment, widely reported and near pure profit, sits inside a US antitrust remedy. A court order ending default-search payments would remove Services dollars that fall almost entirely to the bottom line. Watch the DOJ remedy ruling and the Greater China segment line.

An AI upgrade cycle (right tail). R&D up 33% is Apple funding an Apple Intelligence push it has not yet been paid for. If that triggers a genuine iPhone replacement wave, mid-teens revenue growth sustains and the margin holds, a combination the multiple does not price today. The first sign is the December quarter clearing $150B on device strength.

Closing thoughts

This is a name the market prices thoroughly: twenty-two analysts, near-total coverage, 37 times earnings against a twelve-year range that topped out around there. The edge is not information, it is judgment on one number. On the other side of the wager are bulls paying for an AI supercycle and permanent margin, and bears who see a peak-mix quarter and a China and antitrust overhang. The print that resolves it is concrete and dated: the December quarter's revenue and gross-margin lines, due late January. The left tail is the fatter one here, only because the multiple leaves no room. A slide to 46% to 47% margin compresses 37 times toward the high-20s and takes a quarter of the price with it even on flat earnings. Survivability, though, is absolute, with 50-cent-on-the-dollar gross margins, $90B a year of buyback and net debt of approximately $45B.

The bet is still that people keep buying iPhones and keep paying Apple every month for what runs on them, and that Apple keeps an unusually large slice of each dollar while doing it. It breaks if the December quarter shows gross margin back under 49% with revenue growth slipping toward single digits, because that unwinds both engines the 37 times rests on at once. Watch two numbers in the late-January print: the gross-margin line and the year-over-year revenue rate. If margin holds near 50% and revenue holds double digits, the price is expensive but earned. If both roll over together, it was just expensive.
