Summary of Key Terms ISSUER Greystone Housing Impact Investors LP (NYSE: GHI), a Delaware limited partnership. SECURITIES Up to $25,000,000 of Beneficial Unit Certificates representing assignments of limited partnership interests in GHI, with OFFERED an accompanying allocation under the Community Reinvestment Act (“CRA BUCs”). REGISTERED CRA BUCs offered under an effective Form S-3 Registration Statement filed by GHI with the SEC. OFFERING FORM OF CRA BUCs that are issued to investors will be registered in the investor’s name on GHI’s BUC holder records and HOLDING held in the investor’s name at GHI’s transfer agent in book-entry form. This form of holding the securities will assist SECURITIES GHI in ensuring the accuracy of CRA allocations amongst the CRA BUC holders. No physical BUCs certificates will be issued for CRA BUCs. An investor’s subscription materials and statement of ownership provided by the transfer agent will serve as evidence of ownership of the investor’s CRA BUCs. PRICE 2% discount to previous day closing price as quoted on the New York Stock Exchange (“NYSE”). DISTRIBUTION • None. CRA BUCs are not a separate class or series of GHI’s BUCs and thus have the same rights, AND LIQUIDATION preferences, and privileges as GHI’s other Beneficial Unit Certificates. PREFERENCE • CRA BUC holders will be entitled to receive, along with all of GHI’s other holders of Beneficial Unit Certificates, non-cumulative distributions paid as declared by the General Partner, which is typically quarterly. Such distributions will be junior in priority to distributions declared and payable to the holders of GHI’s preferred units of limited partnership interest. LIQUIDITY The CRA BUCs are offered and sold pursuant to GHI’s currently effective Form S-3 registration statement on file with the Securities and Exchange Commission. In addition, the CRA BUCs will be approved for listing on the NYSE. As a result, the CRA BUCs issued to investors in this offering will be freely tradable by such investors. However, any transfer or sale of CRA BUCs by an investor will result in the loss of the investor’s CRA allocation, which may result in the loss to the investor of positive Community Reinvestment Act (“CRA”) consideration by the federal and state bank regulatory agencies with respect to the investor’s investment in the CRA BUCs. If an investor desires to sell or otherwise transfer the investor’s CRA BUCs, the investor must instruct the investor’s brokerage firm to electronically move the CRA BUCs from the investor’s direct registration account at the transfer agent to the investor’s brokerage firm for that broker to sell. Once a transfer request is initiated by the investor’s brokerage firm, we expect that the transfer will clear within three (3) business days. © 2024 Greystone & Co. II LLC. Confidential.
