Key Highlights

• Micron Technology (NASDAQ: MU) surged roughly 16% in premarket to $1,219.60 after Q3 fiscal 2026 revenue of $41.46 billion grew more than 346% year on year and demolished the $35.59 billion consensus, with adjusted EPS of $25.11 crushing the $20.63 estimate.

• Q4 guidance of approximately $50 billion in revenue and $31 EPS both far exceeded Wall Street expectations, with CEO Sanjay Mehrotra warning that memory supply will remain tight beyond 2027 as AI demand structurally outpaces production capacity.

• Mehrotra disclosed 16 strategic customer agreements totalling approximately $22 billion in commitments including roughly $18 billion in cash deposits, providing multi-year revenue visibility that underpins the sustained AI memory demand thesis.

Micron Technology, Inc. (NASDAQ: MU) is surging roughly 16% in premarket trading to $1,219.60 after delivering third-quarter fiscal 2026 results that market commentary described as not merely beating expectations but annihilating them. The stock closed Tuesday's regular session at $1,048.51 before the earnings release, and the premarket move implies a market capitalisation addition of more than $200 billion on a single set of results.

The revenue figure of $41.46 billion represents growth of more than 346% year on year from the prior year's $9.30 billion comparison period, a scale of expansion that reflects both the AI memory demand cycle's acceleration and the degree to which Micron's product mix has shifted toward the highest-specification memory categories. Adjusted EPS of $25.11 against a consensus of $20.63 represents a beat of more than 21%, a margin of outperformance that is extraordinary for a company of Micron's market capitalisation.

The forward guidance was the second shock in the release. Q4 revenue guidance of approximately $50 billion and EPS of $31 both significantly exceeded the Street's pre-earnings projections, establishing that the current quarter is expected to be even stronger than the record Q3. CEO Sanjay Mehrotra's explicit warning that memory supply will remain tight beyond 2027 as AI demand structurally outpaces production capacity is among the most bullish supply-demand assessments a major memory producer has made publicly, and it arrived with the credibility of 16 strategic customer agreements and approximately $22 billion in commitments including roughly $18 billion in cash deposits as supporting evidence.

The customer agreement disclosures are particularly significant because they convert what had been an extrapolated demand thesis into contracted commercial commitments. Cash deposits of approximately $18 billion represent customers paying in advance to secure memory supply, a behaviour that only occurs when buyers believe supply constraints are severe enough and durable enough to justify the capital commitment required to guarantee allocation.

The broader market implications are substantial. SK Hynix, Samsung, and the wider memory and semiconductor supply chain are all expected to benefit from the demand validation Micron's results provide, extending the global semiconductor rally that Micron's earnings have become a reliable catalyst for.
