• Notable footnotes:
  • F1: 55,962 limited partner units (OP Units) in Hannon Armstrong Sustainable Infrastructure, LP are issuable upon vesting/conversion of 55,962 LTIP Units.
  • F2: Vested LTIP Units may convert one-for-one into OP Units; upon conversion the holder can cause the Partnership to redeem OP Units for cash equal to the market value of equivalent shares of the Issuer, or (at the Issuer’s option) receive Issuer common stock on a one-for-one basis, subject to adjustments.
  • F4: The LTIP Units are held in a trust (Steven G. Osgood, trustee); Mr. Osgood has voting and investment power over those units.
• Exhibit: Power of Attorney dated April 30, 2026 (Exhibit No. 24.1).

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.
