Terra Income Fund 6, Inc. Stockholders Approve Merger with and into Terra Property Trust, Inc. and Related Proposals

New York, New York, September 13, 2022 / PRNewswire / – Terra Income Fund 6, Inc. (NYSE:TFSA) (the “Company”) today announced that at the special meeting of stockholders held on September 12, 2022, conducted by means of a virtual meeting held live over the internet, its stockholders approved (i) the merger (the “Merger”) of the Company with and into Terra Merger Sub, LLC (“Merger Sub”), a Delaware limited liability company and a wholly owned subsidiary of Terra Property Trust, Inc. (NYSE:TPTA) (“TPT”), (ii) the amendment of the Company’s charter to remove certain substantive and procedural protections on “Roll-Up Transactions” necessary to facilitate the Merger, and (iii) the Company’s withdrawal of its election to be regulated as a Business Development Company under the Investment Company Act of 1940, as amended. The Merger is expected to close on or about October 1, 2022, subject to customary closing conditions.

As a result of the Merger, each outstanding share of the Company’s common stock, par value $0.001 per share, will be automatically cancelled and converted into the right to receive: (i) 0.595 shares (as such exchange ratio may be adjusted in accordance with the Merger documents) of the newly designated Class B Common Stock, par value $0.01 per share, of TPT (“TPT Class B Common Stock”), and (ii) cash consideration in lieu of any fractional shares of TPT Class B Common Stock otherwise issuable in an amount, rounded to the nearest whole cent, determined by multiplying (x) the fraction of a share of TPT Class B Common to which such holder would otherwise be entitled by (y) $14.38.

The shares of TPT Class B Common Stock issued in the Merger will, except as discussed below with respect to conversion, have identical preferences, rights, powers, restrictions and terms as each other share of TPT’s common stock. On the 180th calendar day (or, if such date is not a business day, the next business day) after the date of initial listing on a national securities exchange of shares of TPT’s Class A Common Stock, $0.01 par value per share (“TPT Class A Common Stock”), or such earlier date (the “First Conversion Date”) as approved by the board of directors of TPT (the “TPT Board”), one-third of the issued and outstanding shares of TPT Class B Common Stock will automatically convert into an equal number of shares of TPT Class A Common Stock. On the 365th calendar day (or, if such date is not a business day, the next business day) after the date of initial listing on a national securities exchange of shares of TPT Class A Common Stock or such earlier date following the First Conversion Date as approved by the TPT Board (the “Second Conversion Date”), one-half of the issued and outstanding shares of Class B Common Stock will automatically convert into an equal number of shares of TPT Class A Common Stock. On the 545th calendar day (or, if such date is not a business day, the next business day) after the date of initial listing on a national securities exchange of shares of Class A Common Stock or such earlier date following the Second Conversion Date as approved by the TPT Board, all of the issued and outstanding shares of TPT Class B Common Stock will automatically convert into an equal number of shares of TPT Class A Common Stock.
