• Vesting/terms (from footnotes): RSUs vest in equal annual installments over 4 years (first vesting 3/1/2027). The option vests 25% after one year, then the remaining 75% in 36 equal monthly installments thereafter, subject to continued service.

Context

• The RSUs represent the contingent right to receive common shares upon vesting; the 120,000-share entry is a stock option award (not an exercise). Neither award involved an open-market purchase or sale, nor were shares sold or exercised at grant. These are compensation grants subject to service-based vesting.
