⚠ Capex Is a Burden Borne in Every CycleHigh threat

The capital intensity that protects the oligopoly is paid for out of Micron's own cash, relentlessly, and it is one of the heaviest burdens in the business. Micron must spend tens of billions of dollars a year on fabs and equipment simply to stay competitive — through booms and busts alike, because falling behind on capacity or technology is fatal in a commodity. This means that even in a downturn, when revenue collapses and the company may be losing money, the capital spending cannot simply stop; the fabs under construction must be finished, the next node must be developed, and the competitive treadmill keeps running. The result is a business that consumes enormous capital across the cycle and generates truly free cash flow only at the peaks.

The current boom sharpens the risk in a familiar way. Flush with record profits, Micron and its two rivals are pouring capital into new capacity — HBM and advanced DRAM — on the assumption that AI demand persists. If it does not, they will have built expensive new fabs into a fading boom, leaving costly capacity idle and depressing returns exactly as the cycle turns down — the classic memory trap of investing at the top. The capital intensity thus works against Micron twice: as a perpetual claim on cash that limits free cash flow across the cycle, and as a temptation to overbuild into peaks that sows the next glut. The barrier keeps competitors out, which is invaluable, but an investor must weigh that against the reality that Micron itself must keep feeding the same wall tens of billions a year, forever, whether or not the cycle rewards the spending — a burden that makes even a good year less cash-generative than the headline profits suggest — a single leading-edge fab runs past $10 billion¹.
