Jeffrey Lipson reported an indirect award of 238,500 LTIP Units granted on March 2, 2026. These incentive units are held through HASI Management HoldCo LLC, where he is a member, and represent equity-based compensation tied to future vesting and conversion conditions.

How many LTIP Units is Jeffrey Lipson associated with after this HASI transaction?

After the reported grant, Lipson is associated with 1,017,090 LTIP Units in which he has a pecuniary interest. According to the disclosure, these units can convert into an equal number of OP Units and potentially into cash or common stock if vesting and partnership conditions are met.

Are Jeffrey Lipson’s LTIP Units in HASI held directly or through an entity?

The LTIP Units are held through HASI Management HoldCo LLC, not directly by Lipson. He is a member of this entity and reports only his proportionate pecuniary interest, expressly disclaiming beneficial ownership beyond that economic stake in the LLC-held units.

What happens to Jeffrey Lipson’s HASI LTIP Units upon vesting and conversion?

Upon vesting and conversion, each LTIP Unit may convert into one OP Unit of the partnership. Lipson can then cause redemption of OP Units for cash equal to the market value of one common share, or receive one HASI common share per OP Unit, subject to stated conditions.

Did any of Jeffrey Lipson’s previously reported HASI LTIP Units fail to vest?

Yes. The filing states that 58,139 LTIP Units previously included in his totals did not vest. The reason given is that certain performance targets for the performance period ended December 31, 2025 were not achieved, so those units were removed from his reported holdings.

How many shares of HASI common stock does Jeffrey Lipson hold directly?

Lipson directly holds 36,925 shares of HA Sustainable Infrastructure Capital, Inc. common stock. This direct ownership position is reported separately from his indirect interest in LTIP Units held through HASI Management HoldCo LLC, reflecting distinct forms of equity exposure.
