SharkWater Trading  •  Semiconductor Desk • Earnings Micron Printed $54 Billion. The Pre-Market Shrugged. October 1, 2026 Bottom Line Up Front Micron (Nasdaq: MU) reported fiscal fourth-quarter revenue of $54.23 billion on September 30, 2026, against $11.32 billion a year earlier and $41.46 billion in the prior quarter (Form 8-K, Exhibit 99.1). It guided fiscal first-quarter 2027 revenue to $61.5 billion, plus or minus $1.5 billion, with non-GAAP gross margin near 86.25 percent versus 87.0 percent printed. The stock closed September 30 at $1,065.11, before the release, and an aggregator showed it about 0.6 percent lower pre-market on October 1. A quadrupling of revenue produced a shrug so far. That tells you what was in the price. The Print Micron reported after the close on September 30. Fiscal fourth-quarter revenue of $54.23 billion is 4.8 times the year-ago quarter and 30.8 percent above the prior quarter. GAAP net income was $37.70 billion, or $32.87 per diluted share. Non-GAAP diluted EPS was $33.42. The board declared a quarterly dividend of $0.15 per share, payable October 29, 2026.

Figures were extracted from the filing by an automated page reader, not hand-checked line by line. Cells marked NOT IN EXCERPT were not returned by the read. The Guide Is the Story The guided midpoint of $61.5 billion is 13.4 percent above the quarter just reported. Sequential growth was 30.8 percent in the quarter that closed and is guided to less than half that pace. The guided non-GAAP gross margin of about 86.25 percent sits 0.75 points below the 87.0 percent printed. Both are my arithmetic on the filed figures. Neither is a miss against a consensus number, because I did not pull a sourced consensus and will not quote one. Price action (StockAnalysis, aggregator, NOT VERIFIED): MU closed September 30 at $1,065.11, before the release, on 30.8 million shares, against a 31.3 million-share 20-day average read on September 29, about 0.98x. Pre-market on October 1 it showed $1,059.00, down 0.57 percent. The same page said Nvidia, Broadcom, AMD and Intel traded higher pre-market. I did not verify those moves. A boat that has already caught the limit does not get more fish from a bigger net. It gets a heavier haul to carry in. The Bull Case Demand visibility. The release credits strategic customer agreements for demand visibility, and the guide calls for another $7 billion or so of quarterly revenue. Cash returns exist. A dividend is declared and a $650 million buyback figure appears for the fiscal year. Neither is large against $37.70 billion of quarterly GAAP net income. The reaction was muted, not negative. A pre-market dip of about half a percent after a print this large is not a sell-the-news rout. The cash session is still untested. The Bear Case Deceleration is guided. Sequential growth is guided from 30.8 percent to about 13.4 percent at the midpoint. Margin rolls over. A guided gross margin below the printed level is the first step down from a peak, if it is one. Capex is heavy. Net capital spending was $10.77 billion in the quarter and $27.37 billion for fiscal 2026, per the release as read. Memory is a cyclical business, and cycles end when supply arrives. The SharkWater Take I would not chase this. A stock that shrugs at a 4.8x revenue print has already priced the cycle at its widest point, and the guide shows the rate of change slowing even while the level rises. The market trades the derivative, not the level. What I am watching is whether the pre-market dip holds or deepens into the cash open and whether the semiconductor peers keep their gains without Micron. If they do, the read-through to AI hardware is intact. If they fade, Micron was the top of the chain. I stand aside until the price tells me which. Tight lines.
