Micron Slides 3% as Massive AI Capex Plan Triggers Post-Earnings Hangover
Micron Technology (MU) shares fell 2.97% to $410.32 on Monday, sharply underperforming a rallying semiconductor sector. Despite reporting record-breaking fiscal second-quarter results last week, the stock is struggling as investors fixate on an aggressive $25 billion capital expenditure plan and signs of intensifying competition in the high-bandwidth memory (HBM) market.
Record Results Meet Market Skepticism
Micron Technology is experiencing a classic 'sell the news' reaction following its fiscal second-quarter earnings report on March 18. While the company delivered what analysts described as a 'blowout' quarter—reporting revenue of $23.86 billion against estimates of $18.90 billion and an adjusted EPS of $12.20 that crushed the $8.50 consensus—the stock has retreated nearly 13% from its all-time high of $471.34 reached immediately after the announcement.
Today's 2.97% drop is particularly notable because it occurs during a broad market rally, with the S&P 500 up 1.64% and peers like Nvidia and AMD gaining ground on reports of geopolitical de-escalation in the Middle East. Micron's idiosyncratic weakness suggests that the market has fully priced in the current AI growth story and is now weighing the heavy costs required to sustain it.
The $25 Billion Question
The primary catalyst for the downward pressure is management's updated capital expenditure (capex) guidance. Micron signaled it will spend upwards of $25 billion in fiscal 2026 to scale production for the next generation of AI hardware, specifically Nvidia’s upcoming 'Vera Rubin' platform. While this spending secures Micron's position as a critical provider of HBM4 and other advanced memory solutions, the sheer scale of the outlay—a 60% increase over the previous year—has raised alarms regarding near-term free cash flow and margin sustainability.
Analysts at Summit Insights recently downgraded the stock from Buy to Hold, noting that while the AI demand is undeniable, the 'price of admission' to the AI inner circle is becoming increasingly expensive. Furthermore, reports that Samsung is nearing final qualification for Nvidia's HBM supply chain have added a layer of competitive anxiety, threatening the near-monopoly profits Micron and SK Hynix have enjoyed during the current shortage.
Divergence from the Semiconductor Pack
While the VanEck Semiconductor ETF (SMH) is trending higher today, Micron’s decline reflects a rotation out of memory-specific plays and into diversified chipmakers or equipment providers. Some institutional investors are reportedly reallocating capital toward semiconductor equipment manufacturers, betting that Micron’s massive capex will benefit the companies selling the tools more than the chipmaker itself in the short term.
Despite the intraday slide, some Wall Street firms remain steadfast. Analysts at Mizuho and Citigroup recently raised their price targets to the $510-$530 range, arguing that the company’s HBM capacity is effectively sold out through the end of 2026. However, for today's session, the focus remains firmly on the risks of overcapacity and the high cost of maintaining a lead in the volatile memory cycle.
Key Takeaways
- Micron shares fell nearly 3% to $410.32, diverging from a 1.6% gain in the S&P 500 and a broader semiconductor rally.
- Investors are reacting negatively to a projected $25 billion capex ramp for fiscal 2026, fearing it will crimp free cash flow despite record revenue.
- The stock has entered a correction phase, down roughly 13% from its post-earnings peak of $471.34 as profit-taking accelerates.
- Increased competition from Samsung in the Nvidia HBM supply chain is creating headwinds for Micron's premium valuation.
