ACM Research (ACMR) Director Liu Tracy Receives Equity Award

What Happened

• Liu Tracy, a director of ACM Research, was granted two types of equity awards on August 12, 2026: 6,400 derivative awards (option-like) and 728 restricted stock units (RSUs). The filing shows $0 as the acquisition price because these are grants/derivative awards rather than open-market purchases. There was no immediate sale reported.

Key Details

• Transaction date: 2026-08-12 (reported on Form 4 filed 2026-08-26).
• Reported acquisition price: $0 (award/derivative grants).
• Shares owned after transaction: not disclosed in the provided filing excerpt.
• Footnotes/vesting:
  • F1: The 6,400 option-like award will vest and become exercisable immediately prior to the issuer’s 2027 annual meeting, subject to continued service.
  • F2: The per-unit price for the RSUs is based on the average closing price for the 30 trading days before the grant.
  • F3: The 728 RSUs are scheduled to vest immediately prior to the 2027 annual meeting, subject to continued service.
• Timeliness: The Form 4 was filed 14 days after the transaction date (period of report 2026-08-12, filed 2026-08-26), which is late relative to the typical 2-business-day Form 4 reporting requirement (transactionTimeliness = 'L').

Context

• These awards are compensation/retention grants to a director, not open-market purchases or sales. The economic value depends on future vesting/exercise and the company’s stock price at those times. Because these are grants, they do not by themselves indicate immediate insider buying or selling sentiment.
