What Happened

• Diana Hausman, a director of Immuneering Corp (IMRX), was granted a derivative award on June 11, 2026 for 33,350 shares/units reported at $0.00. The filing reports this as a derivative option award rather than an open-market purchase or sale.

• Amount: 33,350 shares/units; reported acquisition price: $0.00 (derivative).
• Vesting/exercise: The option vests and becomes exercisable in equal monthly installments over a one-year period beginning July 11, 2026, and will be fully vested and exercisable on June 11, 2027 (or at the 2027 annual meeting, whichever is earlier). (Footnote F1)

Context

• This was a compensation-related grant (an option-style derivative award), not a market purchase or sale. The award vests monthly over one year and must be exercised to convert to common shares; no immediate sale or exercise is reported in this filing. Such grants are common for directors as part of compensation and do not by themselves indicate a buying or selling decision by the insider.
