Micron Technology has raised its total share buyback authorization to $35.16 billion, giving the US memory chip maker more room to return money to shareholders. The decision follows record financial results supported by strong demand for memory chips used in artificial intelligence (AI).
Micron’s board approved the increase on October 8, 2026. According to Micron’s 2026 annual filing, about $2.16 billion remained available under its earlier buyback program before the increase. The total authorization now stands at $35.16 billion, but this does not mean the company has already purchased that amount of shares.
Micron Technology is one of the world’s major manufacturers of memory and storage products. Its chips are used in computers, smartphones, servers, and AI systems. As technology companies build more powerful AI platforms, the need for faster and more efficient memory continues to increase.
In its September 30 financial results, Micron reported revenue of $54.23 billion for the fourth quarter of fiscal 2026, up from $11.32 billion a year earlier. Full-year revenue reached approximately $133.19 billion, compared with $37.38 billion in fiscal 2025. These figures highlight the company’s strong growth as demand for advanced memory continues to increase.
One important reason for Micron’s growth is rising demand for high-bandwidth memory (HBM). This type of memory helps powerful AI processors access and move large amounts of data at high speed. HBM is becoming increasingly important for AI training, cloud computing, and modern data centers.
Micron is also expanding its advanced memory products for AI systems. In March 2026, the company confirmed large-volume production of HBM4 memory, designed for Nvidia’s Vera Rubin computing platform. The technology offers higher data speeds and improved power efficiency. Demand for advanced memory is also growing as companies build more powerful systems, including those in Nvidia’s AI server ecosystem.
Despite these achievements, Micron faces growing competition from other semiconductor manufacturers, including Samsung, SK Hynix, and Chinese memory chip companies. These competitors are also working to improve memory performance and increase production.
Micron can begin additional share repurchases under the expanded program from December 9, 2026, in line with restrictions in its US CHIPS Act funding agreements. The program has no fixed expiration date, and the company is not required to use the entire authorized amount. Future repurchases will depend on market conditions, available cash, and other financial priorities.
Micron expects revenue of about $61.5 billion, plus or minus $1.5 billion, in the first quarter of fiscal 2027. This is the company’s forecast rather than a confirmed result. Micron is also investing in new production capacity to meet demand, including its planned memory chip facility in Singapore.
Micron’s expanded buyback plan shows how growing AI demand is affecting the memory chip industry. However, competition, changing chip prices, and power shortages affecting AI data centers remain important challenges. The company’s future performance will depend on its ability to increase production, meet customer demand, and maintain strong financial results.
