PORTLAND, Maine , Feb. 22, 2021 — 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 submission of a critical filing to the FDA related to Re-Tain™ and the Company’s unaudited financial results for the year ended December 31, 2020.

Update on Regulatory Status of Re-Tain™:
The Company recently submitted the last of five significant technical sections required to achieve FDA approval to market Re-Tain™, the Company’s mastitis product under development. A response from the FDA to this Chemistry, Manufacturing and Controls Technical Section is expected during the third quarter of 2021 after the statutory six-month review period. If the FDA issues a Technical Section Complete Letter, the Company would be able to begin initial, limited sales of Re-Tain™ during the fourth quarter of 2021 after the final sixty-day administrative review period. If the FDA issues a Technical Section Incomplete Letter, the Company would re-submit for another six-month review after responding to the FDA inquiries leading to potential market launch during the second quarter of 2022. The Company is taking a prudent approach and planning for a mass market launch during 2022.

Product Sales Results:

• As previously announced, total product sales increased by $1.6 million, or 12%, to $15.3 million during the year ended December 31, 2020 compared to the year ended December 31, 2019.
• Sales of the First Defense^® product line increased by 14% during the year ended December 31, 2020 compared to the year ended December 31, 2019.
• Total product sales increased by $111,000, or 3%, to $3.7 million during the three-month period ended December 31, 2020 compared to the three-month period ended December 31, 2019.

Backlog of Orders:
The Company reported a backlog of orders worth approximately $1.8 million as of December 31, 2020 compared to no backlog as of December 31, 2019. The Company projects that, during the first quarter of 2021, it may sell product equivalent to approximately 92% of the $4.1 million that it estimates to be its current production capacity per quarter, resulting in a sales decrease during the first quarter of 2021 compared to the first quarter 2020. The COVID-19 pandemic affects everyone personally and at work in many tragic ways around the world. It has contributed to the Company’s backlog challenge through staff disruptions, complications with equipment fabrication and interruptions in component supply. The Company is working through it, as efficiently as it can. The Company’s investment to increase its annual production capacity from approximately $16.5 million to approximately $23 million is proceeding on budget and on time for completion during the second quarter of 2021. After fulfilling the backlog and meeting on-going strong demand, the Company plans to build inventory during the second half of 2021 to prepare for peak season sales during the first quarter of 2022 without risk of backlog.

Management’s Discussion:
“Our team did an outstanding job compiling a very extensive and detailed submission to the FDA for Re-Tain™,” commented Michael F. Brigham, President and CEO. “That completes the bulk of the regulatory submission work on our end. Now we continue to maintain our production and quality systems and prepare to respond to any FDA queries and ongoing site inspections.”

“The First Defense^® product line continues to help fund the Re-Tain™ regulatory investment with strong growth over the prior year,” Mr. Brigham concluded. “During 2020, we sold product equivalent to about 93% of the $16.5 million that we estimate to be our current annual production capacity, which was about $1.8 million less than what our customers sought to purchase from us. We are experiencing some growing pains during the first quarter of 2021 while available product is constrained, but by increasing our annual production capacity to approximately $23 million, we can return to a growth mode during the second half of the year and thereafter.”

Other Financial Results:

• Gross margin earned was 45% and 49% of product sales during the years ended December 31, 2020 and 2019, respectively. This decrease is largely due to an increase in fixed manufacturing costs that were incurred during 2020 before the benefits of the increased production output are realized and a shift in product mix in favor of First Defense Tri-Shield^®, which delivers more gross margin per dose at a lower percentage of sales.
• Product development expenses increased by $667,000, or 18%, to $4,355,000 during the year ended December 31, 2020 compared to the year ended December 31, 2019. The increase in this expense was budgeted for and necessary to complete the development work related to Re-Tain™. These expenses included $1.5 million of non-cash depreciation expense during both the years ended December 31, 2020 and 2019.
• The 2020 financial results benefited from $938,000 in other income from the forgiveness of the Company’s Paycheck Protection Program loan from the federal government during the fourth quarter of 2020.
• Net loss was $1,022,000, or $0.14 per share, during the year ended December 31, 2020 compared to net loss of $1,296,000, or $0.19 per share, during the year ended December 31, 2019.
• EBITDA (a non-GAAP financial measure described on page 5 of this press release) increased to $1,893,000 during the year ended December 31, 2020 compared to $1,432,000 during the year ended December 31, 2019.

Non-GAAP 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, however, 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 income before income taxes and certain non-cash expenses 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 start with our reported loss before income taxes because presently we are not paying cash for income taxes and do not anticipate paying cash for income taxes in the near-term future. We calculate non-GAAP income before income taxes and certain non-cash expenses as indicated in the table below:

Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) increased to $1,893,000 during the year ended December 31, 2020 compared to $1,432,000 during the year ended December 31, 2019. The figures reported in the table above differ from the calculation of EBITDA in the following two significant ways:
1) We have not added back interest expense or interest rate swap termination fees because we do pay cash for these expenses; and
2) We have added back stock-based compensation expense because this is a non-cash expense that is not added back to the calculation of EBITDA.
