Context

These are derivative/award units tied to LTIP/OP unit mechanics in the Partnership, not a direct purchase of HASI stock. If and when LTIP Units vest and are converted, the holder may receive cash equal to share market value or shares of HASI common stock per the Partnership Agreement.
Awards and derivatives can be part of long-term incentive plans and don’t necessarily indicate near-term buying or selling intent.
