Arm Downgraded to Hold, Shares Fall 6%

HSBC downgraded Arm Holdings plc from “Buy” to “Hold”, stating that the recent AI‑driven rally has already priced in most of the company’s long‑term growth potential, leaving limited upside in the near term. The brokerage lifted its price target to $315 from $255, a roll‑forward to fiscal‑2029 estimates, which translates to roughly 5 % upside from the July 13 closing price of $298.99.

Arm’s shares closed down 6 % at $281.17 on Tuesday, later edging 0.4 % higher in after‑hours trading to $282.26. Since the “Arm Everywhere” event in March, the stock has surged 122 %, far outpacing the 57 % gain in the Philadelphia Semiconductor Index.

HSBC values Arm at 139 times fiscal‑2027 earnings and 95 times fiscal‑2028 earnings, indicating that the current valuation already reflects the company’s ambitious AI roadmap, which targets $25 billion in revenue and non‑GAAP earnings per share of $9 by fiscal 2031. The brokerage highlighted that near‑term earnings upside is constrained by limited 3‑nanometre foundry capacity at TSMC, restricting shipments of Arm’s AI server CPUs, with meaningful capacity additions expected only in the second half of 2027 and TSMC likely to prioritise existing customers.

Overall, HSBC remains positive on Arm’s long‑term prospects but cautions that the premium valuation leaves little room for further price appreciation in the immediate future.
