S&P Global Ratings raised Micron Technology to BBB+ and assigned a positive outlook, marking another upgrade for the memory-chip maker amid strong demand for artificial-intelligence technologies. The agency identified high-bandwidth memory (HBM), specialized memory used by AI accelerators, as a key contributor to Micron's improved financial performance. S&P had upgraded Micron from BBB- to BBB in February 2026, while Fitch Ratings raised it to BBB+ with a stable outlook in May, citing debt repayment and a stronger balance sheet. S&P later that month reaffirmed its BBB rating with a positive outlook. Micron, one of the world's three major DRAM and NAND memory-chip manufacturers, is competing with Samsung and SK Hynix to expand HBM production. The company reported substantial year-over-year growth in fiscal Q1 2026, driven primarily by AI product demand. Bank of America raised its Micron price target to $1,550 in August 2026, reflecting confidence in the durability of its AI-related momentum. The higher credit rating could reduce Micron's borrowing costs, give it access to institutional investors restricted to higher-rated bonds and provide more flexibility to fund next-generation manufacturing capacity without overleveraging its balance sheet.
