Apple margin hits 50.1% as Microsoft cloud margin slips to 66%

Both companies beat estimates in their most recent reports, but the contrast lies in how they convert sales into profit. Apple's June-quarter operating income rose 26.57%, faster than its 16.4% revenue growth, a sign of margin expansion. That margin came with warnings: tariff refunds added roughly two percentage points, and memory costs rose, which Tim Cook described as "a 100-year flood on the memory pricing." Apple also keeps infrastructure spending light by using a hybrid AI model that combines its own data centers with third-party cloud capacity, and by running Siri AI on the device itself.

Microsoft grew faster at 18.8% revenue growth, but its Microsoft Cloud gross margin fell to 66% as sales shifted toward Azure. Capital expenditures of $45.2 billion left free cash flow at $18.6 billion, and operating cash flow was $58 billion, so reinvestment is absorbing most of the cash. CFO Amy Hood said that "each dollar of CapEx has the potential to support more revenue and higher returns over time," a claim supported by a $677 billion commercial backlog, up 73%.

Apple trades near 45 times earnings, compared with 29 for Microsoft, and Apple shares are up 27.12% year to date versus 8.6% for Microsoft. Upcoming results will test whether Apple's September-quarter gross margin falls within its July guidance of 47% to 48%, and whether Microsoft's efficiency gains lift cloud margins before capex peaks.
