FAQ

How do the 8,486 RSUs granted by MNTS vest over time?

The 8,486 Restricted Stock Units vest in three equal annual installments. Vesting is tied to continued employment, meaning the executive must remain with Momentus Inc. through each vesting date to receive the corresponding one-third portion of the grant.

What does each RSU in the MNTS grant represent for Jon Layman?

Each Restricted Stock Unit in the grant represents a contingent right to receive one share of Momentus Inc. Class A common stock. The shares are delivered only as vesting milestones are met, making this a deferred form of stock-based compensation for the executive.
