ACLS Falls 22.4% in Past Month as Recovery Meets Fresh Margin Pressure
Axcelis Technologies (ACLS) shares fell 22.4% over the past month despite Q2 revenue growth of 10.6% and improved bookings. Margins declined, and backlog remains weak. Management expects mid-single-digit revenue growth in 2026. Memory and power demand show recovery potential, but customer concentration and China exposure add volatility.
