Micron earnings preview: EPS expected to grow year over year 940%, potentially surpassing Nvidia as the S&P 500 largest contributor to profit growth

BlockBeats reported that,September 30, Micron Technology will announce its 2026 fiscal fourth-quarter results after U.S. market close on Wednesday. FactSet data shows that analysts expect Micron's EPS for the quarter ended August to grow approximately 940%year over year. If the forecast materializes, Micron could surpass Nvidia for the first time in at least 2 and become the single largest contributor to third-quarter profit growth for the S&P 500 index.

FactSet expects third-quarter profit for the S&P 500 to grow 29.1%year over year; excluding Micron, the increase would fall to 24%, meaning that the earnings growth of Micron alone would raise the index's overall growth rate by approximately 5 percentage points.AI Increased demand from servers for high-bandwidth memory and other storage products, coupled with relatively limited supply expansion, has driven improvements in memory chip prices and profitability. Micron's contribution ranking to S&P 500 profit growth rose from ninth in the third quarter of last year to sixth in the fourth quarter, and then to third in the first half of this year.

Another focus of this earnings report is the HBM4 mass-production timeline. Susquehanna analyst Mehdi Hosseini expects mass production and shipments of Nvidia's Rubin platform to be concentrated more heavily after 2027 April, so the significant boost from HBM4 to Micron's revenue may be realized mainly in 2027. He expects the average selling price of HBM4 to be more than 50%above current HBM3e levels, and sets Micron's 2027 fiscal-year EPS forecast at approximately 200 USD, above the market consensus of approximately 165 USD. Micron's share price has risen nearly 280%year to date, giving it a market capitalization of approximately 1200000000000 USD.
