Amendment Description On April 16, 2024, Presidio Property Trust, Inc. (“Company,” “we,” “us,” or “our”) filed its Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (“Original Form 10-K”) with the Securities and Exchange Commission (“SEC”). This Amendment is being filed solely to correct two typographical errors in Item 15 of the Original Form 10-K.  Specifically, (i) the column heading titled “December 31, 2023” in the consolidated balance sheets on page F-3 of the financial statements is revised to remove the word “(unaudited)” and (ii) the fifth paragraph of the report of the Company's independent registered public accounting firm on page F-2 of the financial statements is revised to add a reference to Note 2 of the financial statements.        As a result of this Amendment, the certifications pursuant to Section 302 and Section 906 of the Sarbanes-Oxley Act of 2002, filed as exhibits to the Original Form 10-K, have been re-executed and re-filed as of the date of this Amendment and are included as Exhibits 31.1, 31.2 and 32.1.     Except as described above, this Amendment does not amend any other information set forth in the Original Form 10-K, and we have not updated disclosures included therein to reflect any subsequent events. This Amendment should be read in conjunction with the Original Form 10-K.
