Amendment Description This Amendment No. 1 to the Quarterly Report on Form 10-Q/A (the “Amendment”) amends the Quarterly Report on Form 10-Q of ImmuCell Corporation (the “Company”) for the three-month and six-month periods ended June 30, 2022 (the “Original Filing”) that was originally filed with the U.S. Securities and Exchange Commission (SEC) on August 11, 2022. The Original Filing is being restated to reflect the accrual of approximately $222,000 of deferred compensation expense (consisting of earned and unused paid time off) during the first quarter of 2022. This change increases the Company’s administrative expenses and accrued expenses by approximately $222,000 with no impact on its cash position or product sales.In addition, as required by Rule 12b-15 under the Securities Act of 1934, as amended, new certifications by the Company’s principal executive and principal financial officer are filed as exhibits to this Amendment under Part II, “Item 6. Exhibits” hereof.Except as described above, the Amendment does not modify or update the disclosures presented in, or exhibits to, the Original Filing in any way. Those sections of the Original Filing that are unaffected by the Amendment have been included herein as required by the SEC. The Amendment continues to speak as of the date of the Original Filing. Furthermore, the Amendment does not reflect events occurring after the filing of the Original Filing. Accordingly, the Amendment should be read in conjunction with the Company’s other filings made with the SEC pursuant to Section 13(a) or 15(d) of the Exchange Act.
