Micron shares rose in separate Friday and Monday sessions ahead of its Sept. 30 fiscal fourth-quarter report, while the company highlighted a 512GB DDR5 RDIMM for next-generation servers. The module reaches 9,200 MT/s, uses approximately 16 watts and is expected to enter mass production in the second half of 2027. Micron says it can save more than 60% of the energy used by four 128GB modules and deliver up to 1.4 times the performance of 256GB DDR5 configurations in certain analytics applications. Investors are also assessing constrained DRAM and NAND supply, memory pricing, HBM demand, shipment capacity, margins and fiscal 2027 guidance. Stifel forecasts $50.78 billion in fiscal fourth-quarter revenue, while broader Wall Street expectations cited in the source are $50.95 billion in revenue and $31.33 in earnings per share, compared with $3.03 per share and $11.31 billion in revenue a year earlier.
