Viral Amin A 4

What Happened
Viral Amin A, EVP and Chief Risk Officer of HA Sustainable Infrastructure Capital, Inc. (HASI), had 679 shares of common stock withheld by the issuer on March 5, 2026 to satisfy tax withholding obligations related to the vesting of awards.

Context
Tax-withholding disposals like this are routine administrative transactions to cover taxes when equity awards vest and do not necessarily reflect buying or selling sentiment by the insider. The filing also notes the reporter’s interest in long-term incentive plan (LTIP) units convertible into partnership units and potentially redeemable for cash or issuer shares per the partnership agreement — these are equity-compensation mechanics rather than open-market trades.
