Hannon Armstrong: A Relatively Better Green Infrastructure Play Hannon Armstrong (HASI) is a truly unique company. At first glance, it may appear as a traditional utility company with a diversified portfolio of renewables. However, since the company only invests in these renewable assets and doesn''t actually operate them, Hannon Armstrong could qualify as an investment company. Yet, due to its renewable infrastructure assets qualifying as real estate, the company has chosen to qualify as a Real Estate Investment Trust, optimizing its tax structure. This is important since the company pays substantial dividends, thus benefiting shareholders. On the one hand, the company''s growth prospects remain robust, and the dividend is enticing.
