ImmuCell Announces Preliminary, Unaudited Sales

Results for Q1 of 2025

PORTLAND, Maine - April 8, 2025 - 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 first quarter of 2025.

Since the first quarter of 2020, the Company has been providing a

preliminary look at its unaudited top line results soon after the close of the quarter. The Company expects to continue providing this

prompt, preliminary report on product sales until further notice going forward.

During the first quarter of 2025, the Company recorded its all-time

quarterly sales record, exceeding the previous all-time high mark set during the fourth quarter of 2024 by 4%. The strong sales during

the first quarter of 2025 helped, in part, reduce the backlog of orders to $4.0 million as of March 31, 2025, from $4.4 million as of

December 31, 2024. Sales recorded during both the six-month and twelve-month periods ended March 31, 2025 also set all-time records for

"Any amount of backlog is too much because it means we are

not fully meeting customer demand, but the level of production output and sales achieved during the last six months does demonstrate

a strong improvement in our performance compared to 2023 and the first nine months of 2024," commented Michael F. Brigham,

President and CEO of ImmuCell. During the three-month period ended March 31, 2025, annualized sales were approximately 108% of the

Company's estimated full capacity of approximately $30 million per year. During the six-month period ended March 31, 2025,

annualized sales were approximately 105% of the Company's estimated full capacity of approximately $30 million per year. This

full capacity estimate was set as a goal during 2023 and 2024 as the Company's capital investments in facilities and equipment

to increase production capacity was coming online and when production output was limited by certain contamination events. Pushing

production output hard, without contamination, and with improving yields and selling prices, is raising the total production

As previously disclosed by the Company in its Annual Report on Form

10-K that was filed on March 28, 2025 and in a press release dated April 2, 2025, the Company is initiating Investigational Product use

of Re-Tain to test market acceptance of the product through a controlled launch. This exciting initiative reflects

the innovative nature of this novel product and its safety profile and allows us to utilize available inventory before shelf-life expiration

to collect critical product performance data. This opportunity is not, however, expected to generate significant revenue or profit. The

Company made its Non-Administrative New Animal Drug Application (NADA) submission, that included its fourth submission of the CMC Technical

Section, together with the minor technical sections covering All Other Information and Product Labeling during early January of 2025.

Clearing inspectional observations at the facilities of the Company's contract manufacturer is still the critical path constraint
