Amendment Description This Amendment No. 1 on Form 10-K/A (the “Amendment”) amends the Annual Report on Form 10-K of Processa Pharmaceuticals, Inc., a Delaware corporation (“we,” “our,” “us” or the “Company”), for the fiscal year ended December 31, 2025, originally filed with the SEC on March 18, 2026 (the “Original Filing”). This Amendment is being filed to include the information required by Items 10 through 14 of Part III of Form 10-K. This Amendment amends and restates in their entirety Items 10, 11, 12, 13 and 14 of Part III of the Original Filing and the exhibit index set forth in Part IV of the Original Filing. The cover page of the Original Filing is also amended to delete the reference to the incorporation by reference of the registrant’s definitive proxy statement.n addition, pursuant to the rules of the Securities and Exchange Commission (the “SEC”), we have also included as exhibits currently dated certifications required under Section 302 of The Sarbanes-Oxley Act of 2002. We are amending and refiling Part IV to reflect the inclusion of those certifications. Because no financial statements are contained within this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted and we are not including certifications pursuant to Section 906 of The Sarbanes-Oxley Act of 2002.  Except as described above, no other changes have been made to the Original Filing. The Original Filing continues to speak as of the date of the Original Filing, and the Company has not updated the disclosures contained therein to reflect any events which occurred at a date subsequent to the filing of the Original Filing other than as expressly indicated in this Amendment. Accordingly, this Amendment should be read in conjunction with the Original Filing and the Company’s other filings made with the SEC on or subsequent to March 18, 2026.
