$Advanced Energy(AEIS.US)

Advanced Energy (AEIS) is catching the semiconductor upcycle at the right time. FY2026 momentum is strong, with Q2 revenue rising about 30% YoY to US$574m and semiconductor revenue jumping 33% to US$278m. Gross margin also improved to 41.1%, showing that higher volumes are beginning to translate into operating leverage.

The bigger question is what investors are already paying for that growth. TTM revenue is about US$2.04bn, with net income around US$219m. Yet AEIS trades near 47x earnings and roughly 31x EV/EBITDA. That is a hefty multiple for a cyclical semiconductor supplier and leaves limited margin of safety if growth cools.

The bull case rests on AI data-centre power demand, semiconductor recovery and further margin expansion. The risks are equally clear: hyperscaler capex digestion, semiconductor cyclicality, customer concentration, pricing pressure and elevated debt.

Technically, momentum has also weakened, with the stock below its 50-day and 200-day averages.

AEIS has the earnings growth to justify attention, but the valuation leaves little room for disappointment. At this price, execution matters almost as much as growth.
