FOR IMMEDIATE RELEASE:

ImmuCell Announces Financial Results for First Quarter of 2017

PORTLAND, Maine – May 11, 2017 – ImmuCell Corporation (NasdaqCM: ICCC), a growing animal health company that is developing, manufacturing and selling products that improve health and productivity in the dairy and beef industries, today announced unaudited financial results for the quarter ended March 31, 2017.

First Quarter 2017 Overview:

Sales of the First Defense® product line (the Company’s lead product) increased by 18% during the three-month period ended March 31, 2017, in comparison to the same period in 2016. For the three-month period ended March 31, 2017, domestic sales of the First Defense® product line increased by 5%, and international sales increased by 133%, in comparison to the same period in 2016 when international demand was not fully met due to a shortage of inventory. Sales of the First Defense^® product line have increased during 22 of the past 26 quarters in comparison to the same quarter of the immediately preceding year.

“During the period when demand outpaced our production capacity, we were forced to allocate product to customers, and more product was allocated to domestic distributors,” commented Michael F. Brigham, President and CEO. “With our production capacity expanded, international demand now has been fully met.”

The new level of sales demand established during 2015 exceeded the Company’s production capacity and available inventory, resulting in a backlog of First Defense^® orders from early 2015 through the middle of 2016. This prolonged period of order backlog disrupted normal shipping patterns. Investments to increase production capacity were completed at the end of the first quarter of 2016, allowing the Company to reset distributors’ inventory levels and significantly reduce the backlog of orders as of June 30, 2016 and to eliminate it as of September 30, 2016. With distributors’ inventory levels reset, sales were down during the third and fourth quarters of 2016 in comparison to the same periods in 2015, which could result in favorable revenue comparisons during the second half of 2017 versus the second half of 2016.

Market conditions in the dairy and beef industries, including milk pricing and prices for calves, weakened in 2016 compared to 2015. Milk prices have made modest improvements going into 2017.

Balance Sheet Data as of March 31, 2017:

Product Development and Distribution Update:

During the second half of 2017, the Company expects to achieve regulatory approval of First Defense^® Tri-Shield™, a new formulation of its bovine antibodies that combines the bivalent claims (against E. coli and coronavirus) of the First Defense^® capsule with a new rotavirus claim. The First Defense^® Tri-Shield™ product will be available in a gel tube delivery format. The Company is working to also achieve regulatory approval of its bivalent gel tube formulation that is currently sold without claims as First Defense Technology^®. With its increased production capacity, the Company has begun to seek additional distributor partnerships to bring First Defense^® into new international territories.

Mast Out® Update:

During the third quarter of 2016, the Company initiated construction of its $20 million pharmaceutical facility to produce Nisin, the active ingredient in Mast Out^®, a novel treatment for subclinical mastitis in lactating dairy cows. Approximately $7.3 million was capitalized on this project as of March 31, 2017, of which approximately $847,000 was recorded in accounts payable as of March 31, 2017. The Company expects to pay for the remaining $13.5 million of budgeted expenditures with its $7.2 million of cash on hand as of March 31, 2017 and its $7.0 million of available bank debt. Spending on this project is expected to be largely complete by September 30, 2017. The Company is on track and on budget to complete the construction and the installation and qualification of equipment by the first quarter of 2018 to maintain the timeline leading to anticipated FDA approval and market launch in 2019.

Nisin is a bacteriocin that is not used in human medicines and would not contribute to the growing concern that the widespread use of antibiotics could encourage the growth of antibiotic-resistant bacteria (“superbugs”).

“Our groundbreaking product innovation is unlike all other antibiotic treatments on the market today that are used subject to milk discard requirements,” further commented Mr. Brigham. “Currently, mastitis, which costs the dairy industry about $2 billion per year, is treated with traditional antibiotic products, and treatment is generally reserved for clinical infections when the cow produces non-saleable milk. The “zero milk discard” product feature of Mast Out® would make earlier treatment of sick cows economically feasible, while these cows are still producing saleable milk. No other product can provide this kind of value proposition.”
