Micron vs. NVIDIA: Which AI Stock Is the Better Buy After Earnings?

Both Micron and NVIDIA have posted strong revenue growth and expanding margins driven by AI infrastructure demand. Micron's fiscal 2026 revenues reached $133.19 billion with a forward P/E of 5.18, while NVIDIA's Data Center revenues surged 117% to $89 billion with a forward P/E of 23.93. Despite NVIDIA's impressive growth, Micron is positioned as the more compelling buy due to its lower financial leverage (3.3% debt-to-equity vs NVIDIA's 14.1%), more attractive valuation, and potential for sustained growth as it evolves into a vital AI infrastructure supplier.
