Key Details

• Transaction date: 2026-06-03; Form 4 filed: 2026-06-05 (timely under Section 16 rules).
• Transaction type: A (Award/Grant of derivative securities).
• Shares/units granted: 3,553 derivative shares (no cash exchanged).

  • F2: 23,551 LTIP units are issuable/convertible into 23,551 limited partner (OP) units in Hannon Armstrong Sustainable Infrastructure, LP.
  • F3: Vested LTIP units eligible to convert to OP Units one-for-one; upon conversion the holder can require redemption of OP Units for cash equal to the market value of equivalent HASI common shares, or elect to receive HASI common shares, subject to the partnership agreement.

Context

• This filing reports an award of derivative securities tied to long-term incentive plan (LTIP) units and partnership OP Units rather than a straightforward cash purchase or sale. Those LTIP/OP conversion and redemption rights (described in F2–F3) mean the economic value may be realized later as cash or as HASI common shares, subject to vesting and conversion conditions. This is routine compensation/long-term incentive reporting and not an immediate market disposition.
