SMCI

Super Micro is riding the AI infrastructure buildout hard: FY2025 revenue grew 46.6% to $22.0B, the latest leg of a remarkable ramp from $3.56B in FY2021. Operating cash flow surged 166.8% to $1.66B, cash ballooned to $5.17B, and the balance sheet is healthy with $6.30B of equity against a manageable 1.22x liabilities/equity. At $30.66 the stock trades at just 0.8x sales and 18.3x earnings — undemanding multiples for a company growing the top line near 50%, and a clear contrast to the triple-digit sales multiples on other AI names.

The quality of that growth is the catch. Gross margin is only 11.1% and slipping, operating margin is 5.7%, and net margin is 4.8% — SMCI is fundamentally a low-margin hardware assembler whose profits depend on component pricing and volume. Despite the 46.6% revenue gain, net income actually fell 9.0% to $1.05B and diluted EPS dropped 12.5% to $1.68, evidence that pricing/mix pressure and rising costs (R&D up 37.3%) are outrunning scale. The 10-K's own risk summary stresses that sales are "concentrated in a few large customers," so a single hyperscaler pullback could dent revenue sharply.
