Micron Technology stock rises as executives report smooth company execution

　　Micron Technology's stock price once rose as much as 9.9% after the company's Chief Financial Officer, Mark Murphy, told investors that the company is now mass-producing the highly sought-after new HBM4 memory chips.

　　At the Wolfe Research event, Murphy stated that this product line—Micron's latest generation of high-bandwidth memory—is currently being shipped to customers. These chips are designed to help artificial intelligence (AI) computing systems handle the vast amounts of data required to develop and run AI models.

　　“We have already begun shipping HBM4 to customers and expect shipments to increase smoothly in the first quarter,” he said. “This is a quarter ahead of the timeline we mentioned during our December earnings call.”

　　Previously, a report by SemiAnalysis had sparked market concerns that HBM4 might not be usable in Nvidia’s next-generation Vera Rubin product line. Nvidia dominates the production of AI accelerators, which are the core processors driving artificial intelligence computing. Memory components produced by Micron and its competitors provide data storage and management support for these chips.

　　During the Wolfe event, Murphy said he wanted to clarify “some recent inaccurate reports about our HBM4 situation.”

　　“Micron’s execution in technology, product, and manufacturing has been outstanding,” he said. “Our HBM capacity is ramping up smoothly, and as we emphasized a few months ago, our HBM supply for 2026 has already sold out.”

　　Murphy also noted that yields for the product are progressing as expected.

　　Micron’s push into high-bandwidth memory helped make it a star in the chip industry last year, with its stock price surging 239%. The Boise, Idaho-based semiconductor company is now seen as one of the key beneficiaries of the AI boom.

　　However, focusing on HBM has also squeezed capacity for other types of memory, resulting in supply shortages that have now impacted the personal computer and mobile phone industries. Murphy said Wednesday that supply tightness will continue beyond 2026.
