ImmuCell Announces Preliminary, Unaudited Sales

PORTLAND, Maine - July 11, 2023 - ImmuCell

Corporation (Nasdaq: ICCC) ("ImmuCell" or the "Company"), a growing animal health company that develops,

manufactures and markets scientifically proven and practical products that improve the health and productivity of dairy and beef cattle,

today announced preliminary, unaudited sales results for the second quarter of 2023, which ended June 30, 2023.

Preliminary, Unaudited

Total Sales Results:

Sales during the three, six and twelve-month periods ended June 30,

2023 were below the comparable periods ended June 30, 2022 in large part because of the previously disclosed production slowdown implemented

during the first quarter of 2023 to remediate contamination events impacting the Company's manufacturing process. Second quarter

sales increased modestly over the $3.45 million of sales recorded during the first quarter of 2023. Second quarter of 2023 sales could

have increased by more but narrowly missed benefiting from approximately $543,000 worth of finished goods inventory (valued at approximate

sales value) that did not ship until the beginning of July due to cold chain shipping requirements and the July 4th holiday

schedule. As of June 30, 2023, the backlog of orders was equal to approximately $8 million, representing a significant increase from approximately

$2.5 million as of December 31, 2022.

During the four-month period ended June 22, 2023, the standard quality

control test of incoming milk batches met specifications approximately 95% of the time, while approximately 2.5% failed with the balance

currently pending final testing and disposition. The two subsequent standard quality control tests at the middle and end of the production

process have continued to be within specification 100% of the time.

"This data supports our belief that our remediation efforts have

been successful and gives us confidence as we return to full production," commented Michael F. Brigham, President and CEO of ImmuCell.

"For the month of June 2023 alone, production output - which includes the approximate sales value of about $543,000 worth of finished

goods inventory that did not ship until the beginning of July 2023 - increased to approximately $1.91 million in comparison to the monthly

average of approximately $1.08 million during the first five months of the year. We believe that this is a positive indicator for the

second half of 2023."

"In addition, we continue to work to achieve FDA approval to

commercialize Re-Tain ," Mr. Brigham concluded. "As disclosed on June 28, 2023, we expect to make our

third submission of the CMC Technical Section by the end of July 2023. When made, this submission will be subject to a six-month review
