Apple Inc

Apple is an exceptional business, but the price sits above even our most generous estimate of its value

Apple designs iPhones, Macs, iPads and wearables, has partners build them, and earns rising, higher-margin services revenue from the people who use them. On quality it passes every Buffett business test the engine runs. It has 0 loss years in 15 years of filings, operating margin averages 28% with volatility of only 2.8%, and return on invested capital (profit relative to the money tied up in the business) averages 64%. The engine's verdict is a demanding price. At $343.46 the shares sit above our base-case value of $167.47, above the bull case of $270.66, and far above the bear case of $94.62. That leaves a margin of safety of -105% against the twenty-five per cent cushion this lens asks for.

Apple designs smartphones, computers, tablets, wearables and home devices, has outside partners build them, and sells them directly and through carriers and resellers. It then earns recurring revenue from services on top of those devices: the App Store, advertising, cloud storage, AppleCare, subscriptions and payments. The device base is the engine. Services sales rise as more people use Apple hardware, and they carry higher margins than the hardware itself.

• iPhone sales, especially Pro models
• Services: advertising, App Store and cloud
• Size and loyalty of the installed device base
• Product launch cycle and holiday-quarter demand
• Mix of products and services driving gross margin

Inside the circle? The record is unusually steady. There were 0 loss years across 15 years of filings, and operating margin volatility was only 2.8%. That points to a business whose broad economics you can follow. Against this, the filing itself describes short product life cycles and rapid technology change. It also describes tariff and trade risk concentrated in Asian manufacturing, Greater China weakness, and regulation that could force Apple to share innovations or change its platforms. Each of these could change the ten-year picture in ways the history does not show.

Apple's protection comes from an integrated system. It designs the hardware, operating system and services together, and a large base of users and developers keeps that system attractive and costly to leave. The numbers support the filing's account: operating margin averaged 28% with volatility of only 2.8%, reached 32% in the latest year, and return on invested capital (profit relative to the money tied up in the business) averaged 64% with 0 loss years. Holding margins at that level while holding a minority market share against rivals who cut prices is the clearest sign of pricing power. Mix shifts towards Pro iPhones and higher-margin services point the same way, although the excerpts do not show explicit price rises. The moat looks likely to last for many years, but its main risk is regulators and courts forcing open the App Store and platform. That risk sits outside the competitive market and the past record cannot measure it.

Apple returns most of its cash to owners. It buys back shares on a large scale and pays a steadily rising dividend, and it makes few large acquisitions. The long record supports this approach. The share count has shrunk at -4.2% a year, and each dollar retained has been matched by 7.7× of market value. The weak point is price. Buffett's test is that buybacks make sense only below intrinsic value, meaning a conservative estimate of the cash the business will produce over its life. At $343.46, our base-case value is $167.47, so recent repurchases look expensive on our assumptions. The filing gives no view on value when it buys. The reporting is factual and mostly standard legal wording. It does state plainly that gross margins face downward pressure, which is useful to you as an owner.

• Buybacks have shrunk the share count at -4.2% a year. In May 2025 the board authorised a new repurchase programme. The filing does not say what price discipline, if any, guides these purchases.
• The dividend payout has averaged 20% of earnings. Management states an intention to raise it each year, which is a modest and predictable commitment.
• The balance sheet now carries $98.7B of debt and net cash of -$44.0B. So part of the capital return is funded by borrowing. Debt is still small next to earning power: repayment would take 0.9 yrs of normalised owner earnings.
• Acquisitions appear minor in the excerpts. The filing lists the usual risks of new ventures, including inadequate return on capital. The excerpts give no detail on specific deals, so that part of the record is missing.

• FailsMargin of safetyFails

  At $343.46, the price is above the base-case value of $167.47 (the bear case is $94.62), so there is no margin of safety (-105%). The standard lens asks for 25%.

  The owner-earnings yield is 2.0% against a 10-year Treasury yield of 5.1%.

  Why this test

Most of Buffett's business principles point the same way here. Demonstrated, consistent earning power is clear in the record. The durable competitive advantage comes from an integrated system of hardware, software, services and developers. Pricing power shows in margins held while the filing says "Competition has been particularly intense as competitors have aggressively cut prices and lowered product margins." The business does not eat capital: capital spending runs at 1.0× depreciation and cash conversion averages 108%. Owner earnings (cash an owner could take out after the spending needed to stay competitive) are $105.5B on a normalised basis. The retained-earnings test passes at 7.7×. Two cautions apply to the return figures. Return on equity of 171% is inflated by buybacks that have shrunk book value per share at -1.9% a year, and net cash is -$44.0B, so the principle of high returns without undue debt needs a careful reading. Debt is still modest against earning power, at 0.9 yrs of owner earnings. The principles fail at price. Value is discounted future cash, and margin of safety asks for a price well below a conservative estimate. Interest rates are gravity: an owner earnings yield of 2.0% sits below the 5.1% ten-year Treasury. Rational capital allocation says buybacks make sense only below intrinsic value. Repurchases at today's level look expensive on our assumptions, and the filing gives no view on value when it buys. Management is plain about one thing that matters: it says "gross margins will be subject to volatility and downward pressure."

• Services sales and Services gross margin percentage in each annual report

  Services carry the higher margins that support the whole valuation; a slowdown would weaken the growth assumption of 7.3%.

• Regulatory and court rulings on the App Store and platform access

  The filing warns rulings may require the Company to share its innovations with competitors, which is the main threat to the moat that the past record cannot measure.

• Greater China net sales and tariff costs in Products gross margin

  The latest filing reports Greater China sales fell on lower iPhone sales and that tariff costs weighed on Products margin.

• Share repurchase size relative to the gap between price and our value range

  Buybacks above intrinsic value transfer wealth from staying owners to sellers, and recent repurchases are large.

• Effective tax rate and one-off tax items

  The latest profit was helped by a lower tax provision tied to the State Aid Decision, so normalised earnings matter more than the latest figure.

Questions the filings couldn't answer

• How much of the margin strength comes from genuine price rises versus mix shifts towards Pro models and services? The excerpts do not show explicit price increases.
• How large is App Store and advertising income within Services, and how exposed is it to forced platform changes? The excerpts give no split.
• What growth rate and duration would justify $343.46, and is there evidence in the filings that Apple can sustain it above its own record of 7.6%?
