AC Immune (ACIU) Director Monika Buetler Receives RSUs & Options

What Happened
Monika Buetler, a director of AC Immune SA, received a grant of 17,751 restricted share units (RSUs) and a separate grant of options covering 41,667 shares on June 11, 2026. Both grants were recorded at $0 cash paid (standard for compensation grants). These are awards rather than open-market purchases or sales and are typically part of director compensation.

Key Details

  • Transaction date: June 11, 2026; Form 4 filed June 15, 2026 (filed within the required two business days).
  • RSUs: 17,751 units granted under the AC Immune 2016 Stock Option and Incentive Plan (SOIP).
  • Options: 41,667 share options granted under the SOIP; filing notes these options will fully vest on June 10, 2027.
  • Holdings note: Filing indicates inclusion of 70,656 common shares underlying outstanding restricted share units in the reporter’s holdings (per footnote).
  • Price/value: Both entries show $0 cash exchanged (typical for grants). Strike/exercise price for the options is not disclosed in the provided filing details.

Context
RSUs are awards that convert to shares (or their cash value) when they vest; stock options give the holder the right to buy shares at a later date (vesting here completes in one year). These grants are standard compensation for directors and do not by themselves indicate a buy or sell signal in the market. No immediate sale or cashless exercise was reported.
