◆ Inside the Latest Results (2025 & Q3 FY2026)

Micron's recent results are, quite simply, the most extraordinary in the history of the memory industry, and they must be read with both awe at their scale and clarity about their cyclical nature. Fiscal 2025, which ended in August 2025, was already a strong recovery year — revenue rose about 49% to $37.4 billion¹, net income reached $8.5 billion, and diluted earnings were $7.59 a share — as the memory market healed from the brutal fiscal 2023 downturn and the AI-memory demand began to build. That would have been a fine year by any normal standard. It turned out to be merely the on-ramp.

What followed, through fiscal 2026, was a ramp with no precedent in memory. Micron's quarterly revenue climbed from roughly $11 billion to $14 billion to $24 billion to a record $41.5 billion in the May 2026 quarter² — a single quarter that exceeded the entire prior fiscal year — while gross margin exploded from around 45% to nearly 85%. In that record third quarter of fiscal 2026, Micron earned net income of about $28 billion³, or roughly $24.67 a share, at a gross margin of 84.6% and an operating margin above 80% — figures that belong to a software company, not a maker of physical memory chips. The driver was unmistakable: high-bandwidth memory for AI, sold into a supply-starved market on contracts that let the oligopoly's pricing power reach its absolute zenith. Trailing-twelve-month revenue reached about $90 billion and net income about $50 billion, and management guided the next quarter toward the almost surreal figure of $50 billion in revenue⁴.

Two things stand out and must be held together. The first is the sheer power of what HBM and the AI boom have done to memory's economics: a business that lost nearly six billion dollars two years earlier was, by mid-2026, one of the most profitable enterprises in technology, its margins transformed, its most valuable product effectively sold out, its every metric a record. This is genuine, and it reflects a real structural development — HBM is a true differentiator, and the AI demand behind it is serious. The second is that these are, unmistakably, peak-cycle numbers. An 84.6% gross margin on memory is not a level that persists; it is the top of the greatest boom the industry has ever seen, the product of an extreme supply-demand imbalance that all three makers are now investing furiously to close.

The honest way to read these results is as simultaneously a triumph and a warning. They prove the power of the HBM franchise, the reality of the AI-memory demand, and the leverage of the oligopoly's pricing power at the top of the cycle — everything the bull case rests on. And they display, in the most vivid possible form, exactly what makes memory so dangerous: numbers this far above any sustainable norm are, by their nature, a peak, and the capital now being poured into capacity to capture them is the seed of the next glut. The market's response — a modest multiple on record earnings — captures the ambivalence perfectly: these are spectacular, historic results, and the market, having watched memory's booms give way to busts many times before, is pricing them as the summit they almost certainly are. Read them as proof of the franchise's power and the AI era's pull through Micron's fabs — and as a reminder that in memory, the most glorious results are the ones to view with the most caution, because the cycle that produced them has never, in the whole history of the business, failed to turn.
