📅 報告日期：2026年5月15日
ACM Research 於2026年5月12日與多名投資者簽訂證券購買協議，進行一項註冊直接發行（Registered Direct Offering）。該公司於2026年5月15日完成交割，按每股52美元價格發行合共2,884,615股A類普通股，並從中獲得約1.498億美元淨集資金額（已扣除預計發行開支）。
是次發行是根據已提交SEC的S-3表格儲架登記聲明及2026年5月12日提交的相關招股章程補充文件進行。集資所得將用於一般企業用途。
🔍 對投資者的潛在影響：
- 短期內股權輕微攤薄，但同時顯著增強公司現金儲備，有助支持未來營運及擴張計劃。
- 以52美元定價，反映市場對ACM半導體設備業務的估值水平。
- 由於屬儲架註冊發行，流程較快，減少市場不確定性。
🔚 本報告不構成出售要約或購買邀請，僅如實披露已完成集資安排。
