That is the number Micron printed on its latest quarterly filing, and it is the number that matters to anyone writing a purchase order for DRAM this fiscal year. The margin means the silicon, the packaging, and the test bench together cost the company 13.75 cents on every dollar of selling price. The buyer pays the other 86.25.

The quarterly profit figure that follows is over $53 billion. Paired with that margin, the number implies a revenue base in the low sixties of billions for a single quarter, a scale no DRAM supplier has posted in the commodity era. The filing does not stamp a calendar quarter on the figure, which is the first gap a procurement lead will notice.

The second number in the document is a date: 2028. Micron projects that RAM shortages tighten through that year, not ease. For a systems integrator locking a BOM in Q3, that is a four-year supply-risk window with no named SKU, no node, and no product family attached to the projection. It treats "RAM" as a single category.

What the document does not prove is that the 86.25 percent margin is sustainable across product lines, or that the $53 billion figure is not a one-time inventory revaluation. No HBM-versus-DDR split is given. The buyer cannot separate the margin on a commodity DDR5 die from the margin on a high-bandwidth memory stack, and that is the distinction that determines whether next year's PO price holds. The filing is a headline number without a P&L line-item breakdown.

What remains unmeasured: the specific quarter, the product mix, the fab utilization behind the margin, and whether the 2028 shortage projection carries a capacity commitment or is a demand-side forecast only. Watch for the next earnings call to name a node and a gigabit-per-wafer figure. Until then, the 86.25 percent is a ceiling, not a floor, and the 2028 date is a warning without a mitigation plan.

The filing names no quarter, no node, and no product split, so the 86.25 percent margin cannot be attributed to a specific die or stack. The 2028 shortage projection is a demand-side warning without a capacity commitment attached.

Without a P&L line-item breakdown or a named node, the 86.25 percent gross margin is a blended figure that conflates commodity DDR and high-bandwidth memory economics. The 2028 date functions as a procurement risk flag, not a supply plan.
