ARM HOLDINGS PLC /UK vs MARVELL TECHNOLOGY, INC, two Semiconductors stocks. A side-by-side on valuation, growth, margins, returns, and what each price is betting.
Both balance sheets are conservative, but Arm's is austere: zero debt and a current ratio of 6, a royalty collector sitting on its float, against Marvell's still-light 0.27 and 3.3. The safety is not what either price is about. Arm trades at 394 times trailing earnings on a 97.9% gross margin, the purest toll-booth economics in semiconductors attached to the most demanding multiple; Marvell trades at 91 times on hopes its AI networking silicon lifts a 14% operating margin toward something worthy of the price. Free cash against price is thin at both, 0.3% and 0.7%. Two licenses to dream, one printed on royalties, the other on design wins.
