FAQ

What did BeOne Medicines (ONC) disclose about its CFO in this Form 4?

BeOne Medicines disclosed that CFO Aaron Rosenberg received two equity awards of ordinary shares tied to performance share units. These grants are part of his compensation and increase his direct share ownership in the company, with vesting scheduled over 2027 and 2028.

How many BeOne Medicines (ONC) shares were granted to the CFO?

The CFO was granted 79,014 ordinary shares underlying earned performance share units vesting in 2027 and 40,573 ordinary shares vesting in 2028. These awards represent compensation, not open-market purchases, and are contingent on continued service to BeOne Medicines.

When do the new BeOne Medicines (ONC) performance share units vest for the CFO?

The earned performance share units underlying 79,014 ordinary shares are scheduled to vest in 2027, and those underlying 40,573 ordinary shares in 2028. Vesting requires the CFO to continue providing service through each vesting date, with potential acceleration on certain termination events.

Are the BeOne Medicines (ONC) CFO’s new share awards immediately owned without conditions?

No, the grants are subject to vesting conditions. The ordinary shares correspond to earned performance share units that vest in 2027 and 2028 only if the CFO continues service. Unvested awards may vest earlier if specific termination events trigger accelerated vesting provisions.

How did these awards change the BeOne Medicines (ONC) CFO’s shareholdings?

After the March 6, 2026 awards, the CFO’s direct holdings rose to 334,919 ordinary shares. This increase reflects compensation-related grants rather than market transactions, providing him with additional equity exposure aligned with BeOne Medicines’ future performance and service-based vesting.

Do the BeOne Medicines (ONC) CFO’s new awards involve a cash purchase of shares?

No, the awards were recorded at a price per share of $0.0000, indicating they were granted as equity compensation rather than bought for cash. They represent performance-based share units that convert into ordinary shares upon satisfying future vesting and service conditions.
