NEW YORK, July 17, 2026 – Micron Technology (NASDAQ:MU) saw its shares decline 5.65% in Thursday's session, closing at $853.20, as the broader semiconductor sector faced headwinds. The Nasdaq Composite fell 1.47% on the day, with memory-chip makers leading the downturn. A delayed premarket quote at 5:48 a.m. indicated a further drop of 2.72% to around $830.
The decline came despite Micron announcing fresh long-term agreements with seven automotive technology partners, including Qualcomm (NASDAQ:QCOM). These deals are intended to enhance both supply and pricing clarity. However, investors remain focused on the scale of Micron's data center business, which continues to dominate its revenue mix.
Revenue Breakdown Highlights Data Center Reliance
In the fiscal third quarter, Micron generated total revenue of $41.46 billion. Data center segments accounted for $25.29 billion, or 61.0% of total revenue, while automotive and embedded contributed $4.63 billion, or 11.2%. The remaining revenue came from mobile and client segments, which contributed $11.52 billion (27.8%). Gross margins were highest in core data center and mobile/client segments at 87%, compared to 79% for automotive.
The gap between data center and automotive revenue is significant. While the new automotive agreements could add some stability to revenue, at their current scale they are not enough to offset any reduction in hyperscaler demand. Chief Executive Sanjay Mehrotra stated that the agreements are expected to strengthen the durability and predictability of Micron's results, but the company did not disclose contract amounts, quantities, or pricing terms.
Valuation Spread Signals Investor Caution
Micron ended Thursday with a trailing price-to-earnings ratio of 19.3. A first-pass estimate, annualizing its $31 non-GAAP EPS midpoint for the quarter, produces a multiple of 6.9. This spread indicates that investors anticipate today's earnings momentum will slow. Auto contracts could help cushion this slowdown, but their current contribution to revenue is not sufficient on its own to lift the stock.
Micron's relative performance was better than some peers. Western Digital (NASDAQ:WDC) slid 9.15%, while Sandisk (NASDAQ:SNDK) lost 12.63%. Analysts suggested that Micron's more diversified offerings may have contributed to its relative resilience.
Market Sentiment and Upcoming Catalysts
Optimism from the previous week dissipated swiftly. Micron jumped around 8% on July 9 after announcing it would increase its planned U.S. investment to over $250 billion by 2035. However, by Thursday, the stock had recorded a five-day decline of 12.88%.
The next test of demand comes Wednesday, July 22, when Alphabet (NASDAQ:GOOGL) will report earnings, with attention on AI-related capital spending. Kevin Mahn, chief investment officer at Hennion & Walsh, highlighted the potential risk, warning that a reduction in hyperscaler spending could ripple across the entire AI ecosystem.
Micron's 15-cent dividend will be paid on Tuesday. Risks persist, including the possibility of reduced hyperscaler spending impacting Micron's main revenue segment. Premarket quotes typically have less liquidity and greater volatility, and the details of contract economics have not been revealed. At present, Micron's share price movement continues to be guided by demand from data centers.
