We are short Hannon Armstrong Sustainable Infrastructure Capital, Inc. (HASI) because its accounting is so complex and misleading that its financial statements are effectively meaningless. HASI is a prime example of how public market incentives can warp a company into relentlessly destroying value to feed a Wall Street growth narrative. Most of HASI’s income is both non-cash and unrealizable: It has little relationship with cash to be received in the future.
