PORTLAND, Maine, May 14, 2024 — 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 its unaudited financial results for the quarter ended March 31, 2024.

Management’s Discussion:
“Our preliminary, unaudited product sales for the first quarter of 2024 were first reported on April 9, 2024,” commented Michael F. Brigham, President and CEO of ImmuCell. “We have no changes to those figures.”

Total sales during the three-month period ended March 31, 2024 were 111% above the comparable period ended March 31, 2023. Total sales during the trailing twelve-month period ended March 31, 2024 were 33% above the comparable period ended March 31, 2023. The $7.3 million in sales recorded during the first quarter of 2024 represents an all-time quarterly sales record for the Company. The next highest quarter was $6 million recorded during the first quarter of 2022.

After a slowdown during 2023 that was necessary to remediate certain production contamination events, finished goods produced increased steadily from approximately $3.3 million to $4 million during the first and second quarters of 2023, respectively, and then further to the average of $5.2 million per quarter during the six-month period ended December 31, 2023. The Company’s objective is to produce finished goods with an approximate sales value of $6 million or more per quarter, which would annualize to about 80% or more of its estimated full production capacity of approximately $30 million. The actual value of the Company’s production capacity varies based on biological and process yields, product format mix, selling price and other factors.

“By implementing and optimizing a multi-year investment to increase our production capacity, we achieved $7.2 million of production during the first quarter of 2024, which annualizes to $28.7 million, or about 96% of our $30 million full capacity estimate,” continued Mr. Brigham.

As the work to increase production output to meet demand continues, the backlog of orders was worth approximately $9.1 million as of March 31, 2024, which is a small decrease from approximately $9.4 million as of December 31, 2023 but still a large increase from approximately $2.5 million as of December 31, 2022.
Certain Financial Results:

• Product sales increased by 111%, or $3.8 million, to $7.3 million during the three-month period ended March 31, 2024 compared to $3.4 million during the three-month period ended March 31, 2023.
• Product sales increased by 33%, or $5.3 million, to $21.3 million during the trailing twelve-month period ended March 31, 2024 compared to $16 million during the trailing twelve-month period ended March 31, 2023.
• Gross margin earned was 32% and 9% of product sales during the three-month periods ended March 31, 2024 and 2023, respectively. The lower gross margin during the three-month period ended March 31, 2023 was largely the result of product contamination events in the production processes that resulted in a slowdown in output and write-offs of scrapped inventory. Remediation measures have been implemented that are anticipated to mitigate the risk of future contamination events.
• Net loss was $438,000, or $0.06 per basic share, during the three-month period ended March 31, 2024 in comparison to a net loss of $2.3 million, or $0.30 per basic share, during the three-month period ended March 31, 2023.
• EBITDA (a non-GAAP financial measure described on page 5 of this press release) improved to approximately $377,000 during the three-month period ended March 31, 2024 in contrast to ($1.6) million during the three-month period ended March 31, 2023.

Balance Sheet Data as of March 31, 2024:

• Cash and cash equivalents decreased to $960,000 as of March 31, 2024 from $979,000 as of December 31, 2023, with no draw outstanding on the available $1 million line of credit as of these dates.
• Net working capital decreased to approximately $7.2 million as of March 31, 2024 from $7.3 million as of December 31, 2023.
• Stockholders’ equity decreased to $24.6 million as of March 31, 2024 from $25 million as of December 31, 2023.

Update on Re-Tain^® Product Development Initiative:
The FDA recently issued a CMC Technical Section Incomplete Letter (Incomplete Letter) to the Company in response to its third CMC Technical Section submission for Re-Tain^®. Pursuant to the Incomplete Letter, the FDA has provided some minor questions about the Company’s submission requiring a re-submission of the CMC Technical Section, which is typically subject to a six-month review. However, the FDA has indicated that this re-submission potentially could be handled through a shortened review period because the open items are not complex. More critical to the timeline, however, is that the FDA has also required that the Company not re-submit the CMC Technical Section until inspectional observations at the facilities of its Drug Product (DP) contract manufacturer are resolved. Given the unique facts and circumstances, the Company is working with the FDA and its DP contract manufacturer to obtain an expedited review.

“We will remain focused on the commercial opportunity we have with First Defense^®, and we intend to persist through yet another regulatory delay in our effort to bring Re-Tain^® to market,” Mr. Brigham concluded.

Non-GAAP Financial Measures:

Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. The non-GAAP measures included in this press release should be considered in addition to, and not as a substitute for or superior to, the comparable measure prepared in accordance with GAAP. We believe that considering the non-GAAP measure of Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) assists management and investors by looking at our performance across reporting periods on a consistent basis excluding these certain charges that are not uses of cash from our reported loss before income taxes. We calculate EBITDA as described in the following table:

EBITDA included stock-based compensation expense of approximately $81,000 and $96,000 during the three-month periods ended March 31, 2024 and 2023, respectively, which is a non-cash expense that management adds back to EBITDA when assessing its cash flows. Cash payments to satisfy debt repayment obligations or to make capital expenditure investments are other uses of cash that are not included in the calculation of EBITDA, which management considers when assessing its cash flows.
