Amendment Description	EXPLANATORY NOTESocietal CDMO, Inc. (“we,” “us,” “our,” the “Company,” or “Societal”) is filing this Amendment No. 1 on Form 10-K/A (“Form 10-K/A”) to amend our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (“2023 Form 10-K”), as filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 22, 2024, to include the information required by Items 10 through 14 of Part III of Form 10-K. This information was previously omitted from the 2023 Form 10-K in reliance on General Instruction G(3) to Form 10-K. This Form 10-K/A amends and restates in their entirety Items 10, 11, 12, 13 and 14 of Part III of the 2023 Form 10-K. The cover page of the 2023 Form 10-K is also amended to update the number of outstanding shares of common stock as of April 1, 2024.Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), this Form 10-K/A amends Item 15 of Part IV of the 2023 Form 10-K solely to update the exhibit list to include new certifications by our principal executive officer and principal financial officer under Section 302 of the Sarbanes-Oxley Act of 2002. Because no financial statements have been included in this Form 10-K/A and this Form 10-K/A 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. Similarly, because no financial statements have been included in this Form 10-K/A, certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 have been omitted.Except as described above, no other changes have been made to the 2023 Form 10-K, and this Form 10-K/A does not modify, amend or update in any way any of the financial or other disclosure contained in the 2023 Form 10-K. This Form 10-K/A does not reflect events occurring after the date of the filing of the 2023 Form 10-K. Accordingly, this Form 10-K/A should be read in conjunction with the 2023 Form 10-K and with our filings with the SEC subsequent to the 2023 Form 10-K.
