Arm Holding On? Crash Leaves Valuation Still Stretched

What happened

Arm Holdings shares have pulled back sharply from over $400, now at $359, but even after the fall, the stock trades at a staggering 427x earnings. A new Seeking Alpha analysis pegs intrinsic value at just $240, while our conviction sell thesis sees fair value at $320, both well below the current price. The AI tailwind is real—data center royalties more than doubled last quarter—yet ARM remains hostage to smartphone cycles, with mobile processors still driving 43% of royalty revenue. Adding to the caution, the U.S. FTC is probing antitrust concerns as ARM moves into selling its own chips, and export license hurdles in China create further fog. Clustered insider selling in May–June, with several officers liquidating holdings entirely, underscores that the smart money is heading for the exits.

Implication

The AI narrative is enticing but insufficient to offset the valuation risk—at 427x earnings, the market prices in years of flawless execution. Our base-case value of $320 requires sustained >100% data-center royalty growth, a declining mobile mix, and no major regulatory setbacks; any stumble could send shares toward the bear case of $220. Recent insider sales by multiple C‑suite officers, including zero‑holding liquidations, raise trust questions even as management guides for strong near‑term growth. A U.S. antitrust probe and ‘challenging’ export license process for China threaten the core licensing model just as ARM pivots to selling its own chips. We recommend avoiding at current levels; strong‑stomached investors could revisit on a washout toward $250, where the risk‑reward turns favorable.

Thesis delta

The new article's $240 intrinsic value estimate reinforces our potential sell call but introduces a slightly more bearish near-term target than our base case of $320. This widens the gap between market price and fair value, elevating immediate downside risk. However, both analyses agree that the AI data-center growth story is real but not yet sufficient to support current multiples.
