Summary 

ImmuCell Corporation was founded in 1982 and completed an initial public offering of common stock in 1987. 

After achieving approval from the Center for Veterinary Biologics, U.S. Department of Agriculture (USDA) to sell First 
Defense® in 1991, we focused most of our efforts during the 1990’s attempting to develop human product applications of 
the underlying milk protein purification technology. Beginning in 1999, we re-focused our business strategy on the First 
Defense® product line and other products that improve the health and productivity of dairy and beef cattle. The demand 
for animal protein, that must be produced efficiently while ensuring food quality and safety, increases as the human 
population grows. Further, our products help address the growing human health concern about using less antibiotics in 
food-producing animals. We aim to capitalize on the growth in sales of the First Defense® product line (a product that 
provides significant Immediate Immunity™ to newborn dairy and beef livestock) and to revolutionize the mastitis 

1 

 
 
ImmuCell Corporation 

treatment paradigm with Re-Tain™ (formerly Mast Out®), a product we are developing to treat this most significant 
cause of economic loss to the dairy industry. 

During 2000, we began the development of Re-Tain™, our purified Nisin treatment for subclinical mastitis in 

lactating dairy cows. No sales of this product can be made without prior approval of our New Animal Drug 
Application (NADA) by the Center for Veterinary Medicine, U.S. Food and Drug Administration (FDA). We have 
now achieved FDA approval for four out of five of the significant regulatory submissions required for product 
approval. Regulatory achievements to date have significantly reduced the product development risks in the areas of 
safety and effectiveness. Our primary product development focus has now turned to completion of the manufacturing 
objectives required for FDA approval. 

Since 2006, we have made ongoing efforts to maintain compliance with current Good Manufacturing Practice 

(cGMP) regulations in all of our manufacturing operations, which requires a sustained investment that further 
enhances the quality of all of our products and our operating efficiency. As we make process improvements, we 
continue to invest in personnel, equipment and facility modifications to increase the efficiency and quality of our 
operations. 

To provide a portion of the funding needed for the development of Re-Tain™ and expansion of the First 
Defense® product line, we issued an aggregate of 2,401,497 shares of common stock, raising gross proceeds of 
approximately $13.46 million in four separate transactions during 2017 and 2016. In order to minimize the dilutive 
effects of these transactions on our existing stockholders, we chose not to issue any form of convertible or preferred 
securities and issued these common shares without any warrants. During 2017 and 2016, we also secured 
approximately $6.8 million in new debt. We have invested this new capital to complete the development of Re-Tain™ 
without relying on funding from a partner or licensee, thereby keeping control over all product rights and potential 
revenues. 

Our operations have been generally profitable, except when we have elected to make unusually large 

investments in product development expenses for future growth. During the twenty years in which we have focused on 
products for the dairy and beef industries, we have funded our operations and improved our net financial position, as 
demonstrated in the following table (in thousands, except for percentages):

Animal Health Products 

The First Defense® product line is manufactured from hyperimmune cows’ colostrum (the antibody rich milk 

that a cow produces immediately after giving birth) utilizing our proprietary vaccine and milk protein purification 
technologies. The First Defense® product line provides bovine antibodies that newborn calves need but are unable to 
produce on their own immediately after birth. The target disease, calf scours (bovine enteritis), causes diarrhea and 
dehydration in newborn calves and often leads to serious sickness and even death. The First Defense® product line is 
the only USDA-licensed, orally delivered scours preventive product on the market for calves with claims against E. 
coli K99, coronavirus and rotavirus (three leading causes of scours). A single dose of our product provides a 
guaranteed level of protection proven to reduce mortality and morbidity. Our milk antibody products provide 
Immediate Immunity™ during the first few critical days of life when calves need this protection most. Studies have 

2 

 
 
 
 
 
 
 
 
 
 
 
ImmuCell Corporation 

shown that calves that scour are more susceptible to other diseases later in life and under-perform calves that do not 
contract scours. The direct, two-part mode-of-action of the First Defense® product line delivers specific 
immunoglobulins at the gut level to immediately protect against disease, while also providing additional antibodies 
that are absorbed into the bloodstream. These circulating antibodies function like a natural timed-release mechanism, 
as they are re-secreted into the gut later to provide extended protection. The First Defense® product line is convenient 
to use. A calf needs to receive only one dose of First Defense® within the first twelve hours after birth. The capsule 
format of this product is stored at room temperature and no mixing is required before it is given to the calf. The gel 
tube formats of this product require refrigeration in accordance with product label indications. We are a leader in the 
scours prevention market with this product. The third quarter of 2018 marked the 27th anniversary of the original 
USDA approval of this product in 1991. During the fourth quarter of 2018, our cumulative sales of First Defense® 
since inception exceeded 22,000,000 doses. We believe that these milestones demonstrate the value of our technology 
and the long-term market acceptance of our product. 

We believe that the long-term growth in sales of the First Defense® product line may reflect, at least in part, the 

success of our strategic decision initiated in 2010 to invest in additional sales and marketing efforts to help us intro-
duce the expanding First Defense® product line to new customers. We launched a communications campaign at the 
end of 2010 that continues to emphasize how the unique ability of the First Defense® product line to provide Im-
mediate Immunity™ generates a dependable and competitive return on investment for dairy and beef producers. 
Preventing newborn calves from becoming sick helps them to reach their genetic potential and reduces the need to use 
treatment antibiotics later in life.   

Our new product line extension, Tri-Shield First Defense, is the first calf-level, passive antibody product on 
the market with USDA-approved disease claims providing Immediate Immunity™ against each of the three leading 
causes of calf scours (E. coli, coronavirus and rotavirus). This new product achieved USDA approval during the fourth 
quarter of 2017 and was listed with the Organic Materials Research Institute (OMRI) during the first quarter of 2019, which 
means it can be used on organic farms. Tri-Shield combines the E. coli and coronavirus antibodies contained in our 
bivalent product with a guaranteed level of rotavirus antibody in one preventative dose in a gel tube delivery format. 
This unique breadth of claims further differentiates our product from competitive products on the market that contain 
only one or two of these label claims. Because it is possible that all farms may not have a rotavirus problem, we are 
continuing to sell the bivalent formats of the First Defense product line as options for customers.   

Historically, the primary tool to help combat scours has been to vaccinate the cow with a dam-level scours vac-

cine. With this expanded claim set, we believe we can compete more effectively against these dam-level vaccine 
products that are given to the mother cow to increase the antibody level against specific scours-causing pathogens in the 
colostrum that she produces for her newborn. It is generally believed that only 80% of animals respond to a vaccine, 
which could leave about 20% of calves unprotected. We believe that the variability in a cow’s immune response to 
vaccines creates a sales opportunity for our product. Additionally, our research suggests that treatment protocols for 
dam-level scours vaccine programs are not always followed, leaving even more calves compromised. Our new mar-
keting campaign, Beyond Vaccination, emphasizes that by delivering Immediate Immunity™ directly to the calf 
via  Tri-Shield, producers can reduce stress-causing injections to the cow and save the associated labor for vaccines 
that are more critical to cow health. Reliance on a dam-level scours vaccine requires that money be spent before it is 
known whether the cow is carrying a viable, valued calf. With Tri-Shield, every calf is equally protected and that 
investment can be targeted to the calves that are most critical to the operation. This, in turn, can free up space in the 
cow’s vaccination schedule to improve her immune response to vaccines that are critical to her health.   

First Defense Technology® is a unique whey protein concentrate that is processed utilizing our proprietary 
colostrum (first milk) protein purification methods, for the nutritional and feed supplement markets without the claims 
of our USDA-licensed product. During 2012, we initiated a limited launch of a gel tube delivery format of our First 
Defense Technology® in a gel solution. We achieved USDA claims for this product format during the fourth quarter 
of 2018 and Canadian approval during the first quarter of 2019, and it is now being sold as Dual-Force™ First 
Defense®. We are selling the same concentrated whey proteins in a bulk powder format (no capsule), which is 
delivered with a scoop and mixed with colostrum for feeding to calves. We are working to achieve USDA claims for 
this product format during 2019. During 2011, Milk Products, LLC of Chilton, Wisconsin launched commercial sales 
of their product, Ultra Start® 150 Plus and certain similar private label products, which are colostrum replacers with 
First Defense Technology® Inside.

Other competition for resources that dairy producers allocate to their calf enterprises has been increased by the 

many new products (principally feed supplements) that have been introduced to the calf market. Warm and dry 
weather reduces the producer’s perception of the need for a disease preventative product like the First Defense® 
product line. However, heat stress on calves caused by extremely hot summer weather can increase the incidence of 
scours, just as harsher winter weather benefits our sales. Market conditions in the dairy and beef industries, including 
milk pricing and prices for calves, have weakened since 2014. Milk prices made modest improvements in 2017 over 
the annual averages for 2016 and 2015 but declined by 10% in 2018 in comparison to 2017. Despite the significant 
market volatility affecting both milk prices and feed costs, we continue to increase our sales.   

During the first quarter of 2017, we discontinued the topical wipes product line due to its limited sales growth 

potential and minimal contribution to profits. 

During 2001, we began to offer our own, internally developed California Mastitis Test (CMT). CMT is most 

often used as a quick on-farm diagnostic to determine which quarter of the udder is mastitic. This test can be 
performed at cow-side for early detection of mastitis. CMT products are also made by other manufacturers and are 
readily available to the dairy producer. 

In connection with our acquisition of certain gel formulation technologies during the first quarter of 2016, we 

also acquired private label manufacturing rights covering two feed supplement product lines that we now produce and 
sell under private label relationships with Ridley, USA Inc. of Mankato, MN and Genex Cooperative Inc. of Shawano, 
WI. These products do not utilize our proprietary antibody technology. 

Sales and Markets 

Our sales and marketing team consists of one vice president, seven regional manager positions and one inside 

sales and marketing position. The First Defense® product line and CMT are sold primarily through major animal 
health distributors who, in turn, sell to veterinary clinics, fleet stores and direct to farms. We have experienced 
minimal bad debt with respect to these products. Sales of the First Defense® product line are normally seasonal, with 
higher sales expected during the first quarter, largely driven by the beef calving season, which runs primarily from 
January to April, unlike the dairy industry in which operations generally calve year round. 

We estimate that the total U.S. market for scours preventative products (including sales of our product) that are 
given to newborn calves (the calf-level market) is approximately $18 million annually. With the additional claim for 
our new product (Tri-Shield First Defense®) against rotavirus, we are now competing against the dam-level vaccine 
products that are given to the mother cow to increase the antibody level against specific scours-causing pathogens in 
the colostrum that she produces for her newborn. We estimate that the dam-level product category covers 
approximately twice as many calves as the calf-level product segment reaches. 

The majority of our international sales are to Canada. We price our products in U.S. dollars. To the extent that 

the value of the dollar declines with respect to any other currency, our competitive position may be enhanced. 
Conversely, an increase in the value of the dollar in any country in which we sell products may have the effect of 
increasing the local price of our products, thereby leading to a potential reduction in demand. Generally, our 
international sales have been generated through relationships with in-country distributors that have knowledge of the 
local regulatory and marketing requirements. We are initiating our plan to expand the number of countries to which 
our First Defense® product line is approved for export. Generally, it is our intent to be the holder of these product 
registrations for each country rather than rely on distribution partners to gain and hold these registrations. This is a 
long regulatory process but allows us to maximize the use of our product label claims and avoid long-term exclusive 
distribution agreements. We continue our efforts to grow sales of the First Defense® product line in North America, 
where there are approximately 41,300,000 dairy and beef cows in the United States and 4,645,000 dairy and beef cows 
in Canada. We believe that even greater market opportunities exist in other international territories. There are 
estimated to be approximately 67,400,000 dairy and beef cows in China, 35,450,000 in the European Union, 
18,470,000 in Australia and New Zealand, 11,150,000 in Mexico, 1,700,000 in South Korea and 1,470,000 in Japan. 
The statistics above are provided by an industry compilation of USDA data for 2019. However, industry practices, 
economic conditions, cause of disease, distribution channels and regulatory requirements may differ in these 
international markets from what we experience in North America making it more difficult or costly for us to generate 
and sustain sales volumes at profitable margins in these markets.

We introduced First Defense® into South Korea in 2005 through Medexx Co., Ltd of Gyeonggi-do, Korea and 
its equivalent into Japan in 2007 through NYS Co., Ltd of Iwate, Japan. The business in Japan is currently not active, 
but we hope to resume sales in this territory in the coming quarters. We entered into distribution contracts covering 
certain Middle Eastern countries with Triplest for Drugs and Trade of Madaba, Jordan during the first quarter of 2017 
and covering Iran with Senikco, LLC of Laguna Niguel, CA during the fourth quarter of 2016. 

With Re-Tain™, we are working to expand our product offerings to include an intramammary treatment for 

subclinical mastitis for the mother cow during lactation. Mastitis (inflammation of the mammary gland) is estimated to 
cost the U.S. dairy industry approximately $2 billion in economic harm per year, which makes it the most costly and 
common disease affecting the dairy industry. The disease diminishes the saleable quantity and overall value of milk, in 
addition to causing other herd health and productivity losses. While the benefit of treating clinical mastitis is widely 
known, subclinical mastitis (those cases where cows have infected udders, but still produce saleable milk) is 
associated with its own significant economic losses and is recognized as a substantial contributor to clinical mastitis 
cases. There is a growing awareness of the cascade of adverse events and conditions associated with subclinical 
mastitis for both the dairy producer and the milk processor, including reduced or foregone milk quality premiums, 
lower milk production (some have estimated approximately 1,500 pounds of lost milk, or about $225 at $15.00 per 
hundredweight, per infected cow), shorter shelf life for fluid milk, lower yields and less flavor for cheese, higher rates 
of clinical mastitis, lower conception rates, increased abortions and increased cull rates. Some industry experts have 
estimated that subclinical mastitis costs the U.S. dairy industry approximately $1 billion per year. 

We believe that Re-Tain™ could revolutionize the way that mastitis is treated by making earlier treatment of 

subclinically infected cows economically feasible by not requiring a milk discard during, or for a period of time after, 
treatment, which would be a significant competitive advantage for our product. No other FDA-approved mastitis 
treatment product on the market can offer this value proposition. Because the milk from cows treated with traditional 
antibiotics must be discarded, most dairy producers simply do not treat subclinically infected cows. It is generally 
current practice to treat mastitis only when the disease has progressed to the clinical stage where the milk from an 
infected cow cannot be sold. The ability to treat such cases without a milk discard could revolutionize the way mastitis 
is managed in a herd. It is common practice to move sick cows from their regular herd group to a sick cow group for 
treatment and the related milk discard. This movement causes stress on the cow and a reduction in milk production. 
Cows treated with our product would not have to be moved, allowing this costly drop in production to be avoided. Our 
product likely will be priced at a premium to the traditional antibiotic products currently on the market, which are all 
sold subject to a milk discard requirement. Common milk discard periods cover the duration of treatment and extend 
from 36 to 96 hours after last treatment, depending on the antibiotic. On average, a cow produces approximately 60 to 
80 pounds of milk per day. While milk prices vary significantly, at an average value of $15.00 per 100 pounds, a cow 
produces approximately $9 to $12 worth of milk per day. These estimated figures would result in milk discard costs 
ranging from approximately $32 (for 3.5 days of milk at 60 pounds per day) to $132 (for 11 days of milk at 80 pounds 
per day) per treated animal. We estimate that the approximate cost to the U.S. dairy industry of this discarded milk 
may be around $300 million per year. We believe that the product’s value proposition demonstrates a return on 
investment to the dairy producer and the milk processor that will justify a premium over other mastitis treatments on 
the market today. 

The USDA’s National Animal Health Monitoring System through its Dairy 2014 study suggests that 21% of all 

dairy cows are treated with a mastitis drug, of which approximately 51% are treated with third generation 
cephalosporins. Many fear that the possible overuse of antibiotics in livestock undermines the effectiveness of drugs to 
combat human illnesses and contributes to a rising number of life-threatening human infections from 
antibiotic-resistant bacteria, commonly known as “superbugs”. The FDA is committed to addressing this public health 
risk. Citing concerns about untreatable, life-threatening infections in humans, new FDA and European regulations are 
aimed at restricting the use of antibiotics (including cephalosporins) in food animals and at improving milk quality. 
Regulators have recently increased their monitoring of antibiotic residues in milk and meat. During the first quarter of 
2012, the USDA reduced the allowable level of somatic cell counts (SCC) in milk from 750,000 (cells per milliliter) to 
400,000 at the individual farm level (not a blended calculation of comingled milk) in order to qualify for an EU health 
certification for export. 

The FDA’s Veterinary Feed Directive (VFD) became effective January 1, 2017, restricting the use of medically 

important antibiotics for performance purposes and requiring more oversight of antibiotic usage in food producing 
animals by a veterinarian, and more changes and restrictions relating to antibiotic usage appear to be likely. Several 

5 

 
 
ImmuCell Corporation 

major food processors and retailers have implemented policies addressing this growing public health concern. By 
reducing the risk of antibiotic residues and slowing the development of antibiotic-resistant organisms, we can improve 
food quality and preserve medically important antibiotics for human disease treatment. This would not be a concern 
for Re-Tain™ because Nisin is not used for human health. This current environment could be favorable to the 
introduction of our new product as an alternative to traditional antibiotics such as penicillin and cephalosporins. We 
believe that this changing environment of new regulations and public opinion supports the value of our ongoing 
development and commercialization efforts for Re-Tain™. Additionally, we believe that the use of our First 
Defense® product line is consistent with this trend of reducing the use of antibiotics because the prevention of calf 
scours early in life with our purified colostrum antibodies can reduce the need for treatment antibiotics later in a calf’s 
life. 

It is difficult to estimate the potential size of the market for the treatment of subclinical mastitis because this 

disease is largely left untreated presently. We believe that approximately 20-30% of the U.S. dairy herd is affected by 
subclinical mastitis caused by Gram-positive organisms falling within the claim spectrum of our product. This 
compares to approximately 2% of the U.S. herd that is thought to be infected with clinical mastitis, where 
approximately $60 million per year is spent on drug treatments. We believe that similar market opportunities also exist 
outside of the United States and for the treatment of dry (non-lactating) cows. We expect the Drug Substance 
production facility that we constructed for approximately $20.8 million to have annual production capacity sufficient 
to meet approximately $10 million in sales of Re-Tain™. Our new facility is designed to have enough room to add a 
second fermentation and recovery portion of the production line to be purchased and installed at the cost of 
approximately $7 million to effectively double production output. We would consider making this investment only 
after commercial acceptance of the product is demonstrated. If annual sales exceed approximately $20 million with 
finished product filling services provided by a contractor, we would evaluate all Nisin supply options, factoring in 
efficiencies and yield improvements. Building an additional Drug Substance production facility to meet our needs at 
that time may be the most cost-effective solution. See additional disclosures about our manufacturing strategies and 
capacity under “Product Development” below. 

With a measured approach to expanding our customer-facing staff, it is our objective to increase our current 

annual level of product sales of approximately $11 million to approximately $20 million through both continued 
growth in sales of the First Defense® product line and a successful launch of Re-Tain™ as soon as possible. As 
market penetration for both new products is achieved and additional resources are dedicated to production, sales, 
marketing and technical services, our longer-term goal is to exceed the $30 million level of annual product sales as 
soon as possible during the five-year period after the market launch of Re-Tain™. 

Product Development 

The majority of our product development spending has been focused on the development of Re-Tain™, our 
purified Nisin treatment for subclinical mastitis in lactating cows. During the nineteen-year period that began on 
January 1, 2000 and ended on December 31, 2018, we invested the aggregate of approximately $15,543,000 
(excluding depreciation and the capital cost of our Drug Substance production facility) in the development of this 
product. This estimated allocation reflects only direct expenditures and includes no allocation of product development 
or administrative overhead expenses. Approximately $2.9 million of this investment was offset by related product 
licensing revenues and grant income, most of which was earned from 2001 to 2007.   

Nisin is a bacteriocin that is not used in human medicines and could alleviate some of the social concerns that the 

widespread use of antibiotics encourages the growth of antibiotic-resistant bacteria (“superbugs”). This antibacterial 
peptide is known to be effective against most Gram-positive and some Gram-negative bacteria. Mastitis, which costs the 
dairy industry about $2 billion per year, is currently 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 approved for Re-Tain™ would make earlier treatment of sick cows economically feasible, while these cows 
are still producing saleable milk. No other existing product can provide this kind of value proposition. 

During 2000, we acquired an exclusive license from Nutrition 21, Inc. (formerly Applied Microbiology Inc. or 

AMBI) to develop and market Nisin-based products for animal health applications, which allowed us to initiate the 
development of Re-Tain™. In 2004, we paid Nutrition 21 approximately $965,000 to buy out this royalty and 
milestone-based license to Nisin, thereby acquiring control of the animal health applications of Nisin. Nisin is a well 

6 

 
 
ImmuCell Corporation 

characterized substance, having been used in food preservation applications for over 50 years.  Food-grade Nisin, 
however, cannot be used in pharmaceutical applications because of its low purity.  Our Nisin technology includes 
processing and purification methods to achieve pharmaceutical-grade purity. 

In 2004, we entered into a product development and marketing agreement with Pfizer Animal Health (now known 
as Zoetis) covering this product. That company elected to terminate the agreement in 2007. We believe that this decision 
was not based on any unanticipated efficacy or regulatory issues. Rather, we believe the decision was primarily driven 
by a marketing concern relating to their fear that the milk from treated cows could interfere with the manufacture of 
certain cultured dairy products. Due to the zero milk discard feature, there is a risk that Nisin from the milk of treated 
cows could interfere with the manufacture of certain (but not all) commercial cultured dairy products, such as some 
kinds of cheese and yogurt, if a process tank contains a high enough percentage of milk from treated cows. The impact 
of this potential interference ranges from a delay in the manufacturing process (which does happen at times for other 
reasons) to the less likely stopping of a cheese starter culture. Milk from cows that have been treated with our product that 
is sold exclusively for fluid milk products presents no such risk. We worked with scientists and mastitis experts to 
conduct a formal risk assessment to quantify the impact that milk from treated cows may have on cultured dairy 
products. This study concluded that the dilution of milk from treated cows through comingling with milk from untreated 
cows during normal milk hauling and storage practices reduces the risk of interference with commercial dairy cultures to 
a negligible level when the product is used in accordance with the product label. We do not believe that such a 
premium-priced product will be used as part of a whole herd (“blitz”) treatment protocol, which reduces the risk of 
cheese interference. We do not see this as a significant problem as modern “precision dairying” practices, as well as cost 
and other economic considerations, support reducing the indiscriminate use of drug treatments.   

The NADA for Re-Tain™ is comprised of five principal Technical Sections and one administrative submission 

that are subject to phased review by the FDA. By statute, each Technical Section submission is generally subject to a 
six-month review cycle by the FDA. Each Technical Section can be reviewed and approved separately. Upon review and 
assessment by the FDA that all requirements for a Technical Section have been met, the FDA may issue a Technical 
Section Complete Letter. The current status of our work on these submissions to the FDA is as follows: 

1) 

Environmental Impact: During the third quarter of 2008, we received the Environmental Impact 

Technical Section Complete Letter from the FDA. 

2) 

Target Animal Safety: During the second quarter of 2012, we received the Target Animal Safety 

Technical Section Complete Letter from the FDA. 

3) 

Effectiveness: During the third quarter of 2012, we received the Effectiveness Technical Section 

Complete Letter from the FDA. The draft product label carries claims for the treatment of subclinical mastitis asso-
ciated with Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis, and coagulase-negative 
staphylococci in lactating dairy cattle. In our pivotal effectiveness study, statistically significant cure rates were as-
sociated with a statistically significant reduction in milk somatic cell count, which is an important measure of milk 
quality. 

4)  Human Food Safety (HFS): During the third quarter of 2018, we received the Human Food Safety 
Technical Section Complete Letter from the FDA confirming, among other things, a zero milk discard period and a 
zero meat withhold period during and after treatment with our product.  

5)  Chemistry, Manufacturing and Controls (CMC): Obtaining FDA approval of the CMC Technical 

Section is the final critical step to FDA approval and to initial commercial sales. Implementing Nisin production at 
commercial scale, which is a required component of the CMC Technical Section, has been the most expensive part of 
this project. We previously entered into an agreement with a multi-national pharmaceutical ingredient manufacturer 
for our commercial-scale supplies of Nisin. However, we determined in 2014 that the agreement did not offer us the 
most advantageous supply arrangement in terms of either cost or long-term dependability. We presented this 
product development opportunity to a variety of large and small animal health companies. While such a corporate 
partnership could have provided access to a much larger sales and marketing team and allowed us to avoid the large 
investment in a commercial-scale production facility, the partner would have taken a large share of the gross margin 
from all future product sales of Re-Tain™. The regulatory and marketing feedback about the prospects for this 
product that we received from prospective partners, following their due diligence, was positive. During the third 
quarter of 2014, we completed an investment in facility modifications and processing equipment necessary to pro-

7 

 
 
ImmuCell Corporation 

duce the Nisin Drug Substance (the active pharmaceutical ingredient) at small-scale. This small-scale facility was 
used to i) expand our process knowledge and controls, ii) establish operating ranges for critical process parameters, 
iii) conduct product stability studies, iv) optimize process yields and v) verify the cost of production. We believe 
these efforts have reduced the risks associated with our investment in the commercial-scale production facility. 
During the fourth quarter of 2015, we acquired land nearby to our existing Portland facility for the construction of a 
new commercial-scale Drug Substance manufacturing facility. We commenced construction of this facility during 
the third quarter of 2016 and completed construction during the fourth quarter of 2017. Equipment installation and 
qualification was initiated during the third quarter of 2017 and completed during the third quarter of 2018. The 
total cost of this building and equipment investment was approximately $20.8 million. 

  We made our first phased Drug Substance submission to the FDA of this comprehensive and complex 

Technical Section during the first quarter of 2019. This Technical Section includes data from the Nisin Drug Sub-
stance Registration Batches produced at commercial scale in our new manufacturing facility. This submission is 
subject to a six-month review period. The timing of this first submission does not directly impact the regulatory 
timeline because the second phased Nisin Drug Product submission (which will include responses to the FDA review 
of the first phased submission and detailed information about the manufacturing process and controls for the sterile 
Nisin Drug Product) defines the critical path to product approval. A successful FDA inspection of our manufacturing 
facility must also be achieved. The second phased Drug Product submission, which is also subject to a six-month review 
period, will not be made in time to achieve product approval by our original goal of December 2019.   

  Since 2010, we have been a party to a long-term exclusive product development and contract manufacturing 
agreement with Norbrook Laboratories Limited of Newry, Northern Ireland, an FDA-approved Drug Product manu-
facturer, covering the final formulation, aseptic filling and final packaging services for Re-Tain™. Norbrook has 
provided services to us under this contract throughout the FDA process for use in all of our pivotal studies. During the 
fourth quarter of 2015, this agreement was amended and restated to, among other things, extend the term of the 
agreement to January 1, 2024. It has been our expectation that we would have these services available through both the 
remainder of the development process and approximately the first four years of commercial sales. However, the 
agreement includes a provision potentially entitling Norbrook to terminate the agreement if we fail to receive FDA 
approval for Re-Tain™ by mid-December of 2019. Due to unexpected difficulties and delays encountered by Nor-
brook at this late stage of the development and the usual FDA timeline for processing CMC Technical Sections, we do 
not expect to receive FDA approval by the December 2019 date.    

In anticipation of this potential issue, we have made requests to Norbrook to amend the existing agreement to 

avoid early termination, including a shorter term and increased payments to Norbrook. However, we have not yet 
reached resolution on an amendment, and it remains unclear whether we will be able to reach agreement on a suitable 
amendment, or if we do, for how long we will continue to have access to Norbrook’s services. Consequently, we have 
been actively investigating multiple alternatives, including securing an agreement for such services with another 
qualified third party or performing the services in-house by constructing an aseptic filling capability within our new 
Drug Substance production facility. Because both of these alternatives would likely delay our commencement of 
commercial sales of Re-Tain™ to at least 2021, we believe, in the case of a new third-party manufacturer, and to at 
least 2022, we estimate, in the case of performing these services in-house, our strong preference would be to reach at 
least an interim arrangement with Norbrook, while we pursue the implementation of the chosen alternative in parallel.   

  The option of establishing our own final formulation, aseptic filling and final packaging capability for Drug 

Product would provide us with the longer-term advantage of controlling the entire manufacturing process for 
Re-Tain™ in one facility, thereby reducing our dependence on third parties and potentially reducing our manufac-
turing costs, but it would require us to raise additional capital to fund the cost of the equipment, facility modifications 
and related validation process, which we estimate on a very preliminary basis to be approximately $4 million. This 
equipment would occupy space in our new Drug Substance facility that we had originally intended to use to double our 
Drug Substance manufacturing capacity if warranted by Re-Tain™ sales volumes during the initial years following 
product launch, as discussed above under “Sales and Markets”, thus limiting the maximum production capacity of our 
new Drug Substance facility. This could possibly leave us unable to meet growing customer demand for Re-Tain™ 
until and unless we are able to expand that capacity elsewhere or otherwise relocate certain manufacturing activities to 
enable the expansion to occur.   

After approval of the CMC Technical Section, there is a 60-day administrative review before anticipated 

product license approval can be issued and commercial sales can be initiated.

We are party to a long-term, exclusive supply agreement with Plas-Pak Industries, Inc. (now owned by Nordson 
Corporation) of Norwich, Connecticut covering the proprietary syringe that was developed specifically for treating cows 
with our mastitis product.  These syringes were used for all pivotal studies. During the third quarter of 2017, this 
agreement was extended to January 1, 2024.   

Our second most important product development initiatives (in terms of dollars invested and, we believe, 
potential market impact) have been focused on other improvements, extensions or additions to our First Defense® product 
line. During the second quarter of 2009 we entered into an exclusive license with the Baylor College of Medicine 
covering the underlying rotavirus vaccine technology used to generate the specific antibodies for use with animals. 
This perpetual license (if not terminated for cause) is subject to ongoing royalty payments. We achieved product 
license approval and initiated market launch of this product, Tri-Shield First Defense®, during the fourth quarter of 
2017. During the third quarter of 2018, we obtained approval from the Canadian Food Inspection Agency to sell 
Tri-Shield® in Canada. We expect to initiate sales in Canada after domestic demand is met. We achieved USDA 
approval of our bivalent gel tube formulation (formerly marketed as First Defense Technology®) during the fourth 
quarter of 2018 and have re-branded this product format, together with the bolus format, as Dual-Force™ First Defense®. 
We are currently working to establish USDA claims for our bivalent bulk powder formulation of First Defense 
Technology®. We are also investing in additional studies comparing the First Defense® product line to the 
competition. 

At the same time, we are working to expand our product development pipeline of bacteriocins that can be used as 
alternatives to traditional antibiotics. During the second quarter of 2015, we entered into an exclusive option agreement 
to license new bacteriocin technology from the University of Massachusetts Amherst. During the first quarter of 2019, 
we extended this exclusive option agreement through March 2021. This technology focuses on bacteriocins having 
activity against Gram-negative infections for use in combating mastitis in dairy cattle. Subject to the availability of 
resources, we intend to begin new development projects that are aligned with our core competencies and market focus. 
We also remain interested in acquiring, on suitable terms, other new products and technologies that fit with our sales 
focus on the dairy and beef industries. 

Competition 

Our competition in the animal health market includes other biotechnology companies and major animal health 

companies. Many of these competitors have substantially greater financial, marketing, manufacturing and human 
resources and more extensive product development capabilities than we do. 

We would consider any company that sells an antibiotic to treat mastitis, such as Boehringer Ingelheim, Merck 

Animal Health and Zoetis (formerly Pfizer Animal Health, a division of Pfizer, Inc.), to be among the potential 
competitors with respect to Re-Tain™. We expect the FDA to grant a period of five years of market exclusivity for 
our product (meaning the FDA would not grant approval to a second NADA with the same active drug for a period of 
five years after the first NADA approval is granted) under Section 512(c)(2)F of the Federal Food, Drug, and 
Cosmetic Act. 

There are several other products on the market (some with claims and some without) that are delivered to 
newborn calves to prevent scours. We believe that the First Defense® product line offers two significant competitive 
advantages. First, only the First Defense® product line provides protection against E. coli, coronavirus and rotavirus, 
three of the leading causes of calf scours. Second, being derived from colostrum, our product offers Immediate 
ImmunityTM through antibodies that both function at the gut level and are absorbed into the blood stream for future 
protection. All formats of our product can be administered without delaying or adversely affecting maternal 
colostrum. 

Zoetis sells a product that competes directly with the First Defense® product line in preventing scours via oral 

delivery to newborn calves. Their product (Calf-Guard®) is a modified-live virus vaccine. Newborn calves respond 
poorly to vaccines and the immune system must be given time to develop a response to vaccines. Both our product and 
Calf-Guard® carry claims against coronavirus and rotavirus infections, but this competitive product does not carry a 
claim against E. coli infections like our product does. It is common practice to delay colostrum feeding when dosing a 
calf with Calf-Guard® so that the antibodies in the colostrum do not inactivate the vaccine product. There is no 
nutritional benefit to withholding milk from newborn calves. In contrast, we encourage the feeding of four quarts of 
high quality colostrum immediately after birth when dosing a calf with our product, which is standard practice for 

9 

 
 
ImmuCell Corporation 

good calf health. Because the antibodies in our product would likely work to inactivate a modified-live vaccine, 
rendering it useless or less useful, our product label historically included a precaution that First Defense® should not 
be used within five days of such a vaccine. During the first quarter of 2015, the USDA granted us permission to 
remove this precaution from our label, and we have done so. We believe that this precaution should be required on the 
Calf-Guard® label to prevent inactivation of that product by First Defense® antibodies or colostrum. Our product is 
priced at a premium to Calf-Guard®. 

Elanco Animal Health (a division of Eli Lilly and Company) and Boehringer Ingelheim also sell directly 

competitive products. The Elanco product (Bovine Ecolizer® and Bovine Ecolizer® + C20) was acquired through 
Elanco’s January 2015 acquisition of Novartis Animal Health and carries claims to prevent scours in newborn calves 
caused by E. coli and C. perfringens. The Boehringer product (Bar-Guard-99™) carries claims to prevent scours in 
newborn calves caused by E. coli. These two products are both derived from horse blood rather than the bovine 
colostrum used for the First Defense® product line. Equine antibodies are less efficiently absorbed into the bovine 
bloodstream, so fewer antibodies are re-secreted for additional protection. 

During the fourth quarter of 2016, Merck launched a new competitive product into this market space. This 
product (BOVILIS® Coronavirus) is a modified-live virus intranasal vaccine that carries a claim against coronavirus 
only. 

When compared to the other USDA-approved calf-level scours preventatives, we believe we are first in sales 

dollars and second in volume. This product category is comprised of five (increasing from four until the fourth quarter 
of 2016) primary brands that are given either orally or intranasal to newborn dairy and beef calves immediately after 
birth. Market research that we subscribe to suggests that our product comprised approximately 34% and 33% of the 
total doses sold in this product category (one dose equates to one calf, according to label administration on all 
products) during 2018 and 2017, respectively. These estimates are down from 36% during 2016 and 40% during 2015 
when the product category included only 4 primary brands (one of which experienced lack of supply to the market 
during late 2014 and into the middle of 2015). This market share estimate is slightly up from 32% in 2014 and up from 
26% and 22% in 2013 and 2012, respectively, as the total volume in the product category has steadily increased. These 
estimates do not include sales of vaccine products that are given to the dam (mother cow), which is discussed below. 

With the new rotavirus claim for our product (Tri-Shield First Defense®) we are now competing against 

dam-level vaccine products that are given to the mother cow to increase the antibody level against scours-causing 
pathogens in the colostrum that she produces for her newborn. Those products are sold by Elanco (Scour Bos™), 
Merck (Guardian®) and Zoetis (ScourGuard®). Despite the best-managed dam vaccine program, colostrum quality is 
naturally variable and newborn calves do not always get the antibodies they need from maternal colostrum. We 
believe that the guaranteed dose of antibodies in our product provides more consistent protection than such vaccine 
products. 

We may not be aware of competition that we face, or may face in the future, from other companies. Our 
competitive position will be highly influenced by our ability to attract and retain key scientific, managerial and sales 
personnel, to develop proprietary technologies and products, to obtain USDA, FDA or foreign approvals for new 
products, to effectively promote and market our products, to have available properly licensed, efficient and effective 
raw material and finished product manufacturing resources and to continue to profitably sell our current products. We 
currently compete on the basis of product performance, price and distribution capability. We continue to monitor our 
network of independent distributors to maintain our competitive position. 

Intellectual Property 

We own a broad collection of intellectual property rights relating to our research, products and processes.    This 
includes patents, copyrights, trademarks, trade dress, trade secrets, know-how and other intellectual property rights in 
the United States and other countries. While the Company believes the ownership of its intellectual property rights is 
an important factor in its business and that its success depends in part on such ownership, the Company also relies 
heavily on the innovative skills, technical competence and marketing abilities of its personnel. 

We own: (a) U.S. Patent No. 6,794,181 entitled “Method of Purifying Lantibiotics”, which covers a manufac-
turing  process  for  preparing  pharmaceutical-grade  Nisin,  which  was  issued  in  2004;  and  (b)  U.S.  Patent  No. 
10,023,617 entitled “Methods and Systems of Producing Pharmaceutical Grade Lantibiotics”, which covers key, novel 

10 

 
 
ImmuCell Corporation 

and proprietary aspects of our manufacturing process for preparing pharmaceutical-grade Nisin, and was issued during 
the third quarter of 2018. In the future, we may file additional patent applications for certain products under devel-
opment. There can be no assurance that patents will be issued with respect to any pending or future applications. In 
some cases, we have chosen (and may choose in the future) not to seek patent protection for certain products or pro-
cesses. In those instances, we have sought (and may seek in the future) to maintain the confidentiality of any relevant 
intellectual property and other proprietary rights through operational measures and contractual agreements. 

We  own  numerous  trademarks  and  trade  dress  that  are  very  important  to  our  business,  and  have  several 
trademark and trade dress applications and registrations in the United States, Canada, Iran and Turkey. We own the 
following  U.S.  trademark  registrations:  IMMUCELL,  FIRST  DEFENSE,  FD  FIRST  DEFENSE  (&  Design), 
FIRST  DEFENSE  TECHNOLOGY,  TRI-SHIELD  FIRST  DEFENSE,  TRI-SHIELD  FIRST  DEFENSE  (& 
Design),  YOUR  CALF  CREW,  BEYOND  VACCINATION,  BEYOND  VACCINATION  (&  Design),  CALF 
HERO and TRI-SHIELD. We also own U.S. registrations for the color blue for our blue gel and blue bolus FIRST 
DEFENSE  products.    We  own  pending  U.S.  trademark  applications  for  the  DUAL-FORCE  and  RE-TAIN 
trademarks.  The  United  States  Patent  and  Trademark  Office  issued  a  determination  that  our  IMMEDIATE 
IMMUNITY trademark, which we use in connection with marketing of all of our products, is generic. Rather than 
appeal this finding, we are continuing to build our common law rights in the brand. The FDA issued a determination 
that the name,  MAST  OUT,  which  we had intended to use for our purified Nisin product, is overly promotional. 
Rather than continuing an appeal of this decision, we selected a new product name, RE-TAIN, which was approved 
by the FDA during the first quarter of 2019. During the first quarter of 2017, we sold our registered trademarks related 
to dairy wipes, WIPE OUT and THE ONE STEP COW PREP, when we discontinued that product line. 

Government Regulation 

We believe that we are in compliance with current regulatory requirements relating to our business and products. 
The manufacture and sale of animal health biologicals within the United States is generally regulated by the USDA. We 
have received USDA and Canadian Food Inspection Agency approval for the bolus format of First Defense® and for 
the gel tube formats of Tri-Shield First Defense® and Dual-Force™ First Defense®. Re-Tain™ is regulated by the 
FDA, which regulates veterinary drugs. Regulations in the European Union will likely require that our product be sold 
subject to a milk discard requirement in that territory, although the duration of the milk discard requirement may be 
shorter than the discard requirement applicable to competitive antibiotic products in that market. Comparable agencies 
exist in foreign countries, and foreign sales of our products will be subject to regulation by such agencies. Many 
countries have laws regulating the production, sale, distribution or use of biological products, and we may have to 
obtain approvals from regulatory authorities in countries in which we propose to sell our products. Depending upon the 
product and its applications, obtaining regulatory approvals may be a relatively brief and inexpensive procedure or it 
may involve extensive clinical tests, incurring significant expenses and an approval process of several years’ duration. 
We generally rely on in-country experts to assist us with or to perform international regulatory applications. 

Employees 

We currently employ 51 employees (including 4 part-time employees). Approximately 29 full-time equivalent 

employees are engaged in manufacturing operations, 9.7 full-time equivalent employees in sales and marketing, 6 
full-time equivalent employees in product development activities and 4.3 full-time equivalent employees in finance 
and administration. As needed, we augment our staff with contracted temporary employees. At times, manufacturing 
personnel are also utilized, as needed, in the production of clinical material for use in product development. All of our 
employees are required to execute non-disclosure, non-compete and invention assignment agreements intended to 
protect our rights in our proprietary products. We are not a party to any collective bargaining agreement and consider 
our employee relations to be excellent. 

Public Information 

As a reporting company, we file quarterly and annual reports with the Securities and Exchange Commission 

(SEC) on Form 10-Q and Form 10-K. We also file current reports on Form 8-K, whenever events warrant or require 
such a filing. The public may read and copy any materials that we file with the SEC at the SEC’s Public Reference 
Room at 450 Fifth Street, N.W., Washington, D.C. 20549. The public may obtain information on the operation of the 
Public Reference Room by calling the SEC at 1-800-SEC-0330. The SEC maintains an internet site that contains 
reports, proxy and information statements and other information about us that we file electronically with the SEC at

ITEM 1A — RISK FACTORS 

Projection of net income (loss):  Generally speaking, our financial performance can differ significantly from 

management projections, due to numerous factors that are difficult to predict or that are beyond our control. Weaker than 
expected sales of the First Defense® product line could lead to less profits or an operating loss. Large investments in 
product development (or cost overruns) can result in a net loss. We were profitable during the second half of 2014, 
during the years ended December 31, 2015 and 2016 and during the nine-month period ended September 30, 2017. Dur-
ing the five quarters since then, we have incurred net losses largely due to facility start-up and development costs related to 
our Nisin product development program. Depreciation expenses related to the Drug Substance production facility are 
expected to contribute to reported net losses until and unless product sales increase to offset these non-cash expenses. 

Deferred tax assets: The realizability of our deferred tax assets is a subjective estimate that is contingent upon 

many variables. During the second quarter of 2018, we recorded a full valuation allowance against our deferred tax 
assets that significantly increased our net loss in comparison to other periods. This non-cash expense could be reversed 
in the future if justified by current and near-term projections of profitability. We will continue to assess the need for the 
valuation allowance at each quarter, and in the event that actual results differ from these estimates or we adjust these 
estimates in future periods, we may need to adjust our valuation allowance.   

Reliance on sales of the First Defense®product line:  We are heavily reliant on the market acceptance of the 
First Defense®product line to generate product sales and fund our operations. Our business would not have been prof-
itable during the nine consecutive years in the period ended December 31, 2007 or during the years ended December 31, 
2012, 2013, 2015 and 2016 without the gross margin that we earned on sales of the First Defense®product line, which 
accounted for 97% and 94% of our total product sales during the years ended December 31, 2018 and 2017, respectively.   

Concentration of sales:  Approximately 100% and 98% of our product sales were made to customers in the 

dairy and beef industries throughout the world during the years ended December 31, 2018 and 2017, respectively. 
Approximately 87% and 82% of our product sales were made to customers in the U.S. dairy and beef industries during 
the years ended December 31, 2018 and 2017, respectively. The animal health distribution segment has been ag-
gressively consolidating over the last few years with larger distributors acquiring smaller distributors. A large portion 
of our product sales (66% and 65% during the years ended December 31, 2018 and 2017, respectively) was made to 
two large distributors. A large portion of our trade accounts receivable (72% as of December 31, 2018 and 69% as of 
December 31, 2017) was due from these two distributors. We have a good history with these distributors, but the 
concentration of sales and accounts receivable with a small number of customers does present a risk to us, including 
risks related to such customers experiencing financial difficulties or altering the basis on which they do business with 
us.   

Gross margin on product sales:  It is one of our goals to again achieve a gross margin (before related de-

preciation expenses) as a percentage of total sales close to 50% after the initial launch of new products. Depreciation 
expense will be a larger component of costs of goods sold for Re-Tain™ than it is for First Defense®, and gross margins 
generally improve over time. Many factors discussed in this report impact our costs of goods sold. There is a risk that 
we are not able to achieve our gross margin goals, which would adversely affect our operating results and could impact 
our future operating plans.   

Product risks:  The sale of our products is subject to production, financial, efficacy, regulatory, competitive and 

other market risks. Elevated standards to achieve and maintain regulatory compliance required to sell our products 
continue to evolve. Failure to achieve acceptable biological yields from our production processes can materially increase 
our costs of goods sold and reduce our production output, leading to an order backlog. We have experienced customer 
complaints pertaining to the gel tube format of the First Defense product line about some product that has become 
compacted and not expressible. We believe these failures result from exposure of our original formula to excessive heat 
conditions. This is a risk to achieving and maintaining customer acceptance. The costs associated with replacing defec-
tive product are accounted for in costs of goods sold. We believe we have improved our formulation and production 
processes to prevent this problem going forward and are now incurring added costs to ship this product on dry ice. There 
is no assurance that we will continue to achieve market acceptance at a profitable price level or that we can continue to

manufacture our products at a low enough cost to result in a sufficient gross margin to justify their continued manufac-
ture and sale.   

Product liability:  The manufacture and sale of our products entails a risk of product liability. Our exposure to 

product liability is mitigated to some extent by the fact that our products are principally directed towards the animal 
health market. We have maintained product liability insurance in an amount which we believe is reasonable in relation to 
our potential exposure in this area. We have no history of claims of this nature being made. 

Regulatory requirements for the First Defenseproduct line:  First Defense is sold in the United States 

subject to a product license from the Center for Veterinary Biologics, USDA, which was first obtained in 1991. As 
such, our operations are subject to periodic inspection by the USDA. The potency of serial lots is directly traceable to 
the original serial used to obtain the product performance claims (the “Reference Standard”). Due to the unique nature 
of the label claims, host animal re-testing is not required as long as periodic laboratory analyses continue to support the 
stability of stored Reference Standard. To date, these analyses have demonstrated strong stability. However, if the 
USDA were not to approve requalification of the Reference Standard, additional clinical studies could be required to 
meet regulatory requirements and allow for continued sales of the product. We expect to be subject to similar regulatory 
oversight risks in territories outside of the United States where we sell our products.   

Regulatory requirements for Re-Tain™: The commercial introduction of this product in the United States will 
require us to obtain FDA approval. Completing the development through to approval of the NADA by the FDA involves 
risk. While four of the five required Technical Sections have been approved, the development process timeline has 
been extensive (approximately 19 years) and has involved multiple commercial production strategies. The Chemistry, 
Manufacturing and Controls Technical Section was submitted for the Nisin Drug Substance during the first quarter of 
2019. The timeline for the Nisin Drug Product submission defines the critical path to product approval. To reduce the 
risk associated with this process, we have met with the FDA on multiple occasions to align on filing strategy and 
requirements. We have disclosed a timeline of events that could lead to potential approval during the first half of 2020. 
However, there remains a risk that approval could be delayed or not obtained. We are exposed to additional regulatory 
compliance risks through the subcontractors that we choose to work with to produce Re-Tain™, who also need to 
satisfy certain regulatory requirements in order to provide us with the products and services we need. International 
regulatory approvals would be required for sales outside of the United States. European regulatory authorities are not 
expected to approve a product with a zero milk discard claim, which would remove a significant competitive advantage 
in that territory. However, the assigned milk discard period may be shorter for our product than it is for other products on 
the market in Europe. 

Economics of the dairy and beef industries: 

•  The January count of all cattle and calves in the United States had steadily declined from 97,000,000 as 
of January 1, 2007 to 88,500,000 as of January 1, 2014. Then this figure increased to 89,100,000 as of 
January  1,  2015,  to  91,900,000  as  of  January  1,  2016,  to  93,700,000  as  of  January  1,  2017,  to 
94,300,000 as of January 1, 2018 and to 94,800,000 as of January 1, 2019, which is 0.5% higher than 
at January 1, 2018. 

•  From 1998 through 2018, the size (annual average) of the U.S. dairy herd ranged from approximately 

the low of 9,011,000 (2004) to the high of 9,392,000 (2017). The monthly average for 2018 decreased 
slightly to 9,385,000. 

•  The Class III milk price (an industry benchmark that reflects the value of product used to make cheese) 
is an important indicator because it defines our customers’ revenue level. This annual average milk 
price level (measured in dollars per hundred pounds of milk) reached its highest point ever during 2014 
at $22.34 (peaking at $24.60 in September 2014) since these prices were first reported in 1980. The 
2014 high price for milk corresponds to a low count of cattle and calves of 88,500,000 on January 1, 
2014 and an average annual U.S. dairy herd size of 9,256,000 during 2014. This average annual herd 
size from 1998 to 2013 was always lower than the 2014 level (except for during 2008), and since 
2014 this average annual herd size has always been higher than the 2014 level. This strong milk price 
level during 2014 declined to the average of $15.80 during 2015 and further declined to $14.87 
during 2016, but increased by 9% to $16.17 during 2017 and then declined by 10% to $14.61 during 

13

2018.  The low price level in 2018 is very problematic to the profitability of our customers. The recent 
annual fluctuations in this milk price level are demonstrated in the following table:

•  The actual level of milk prices may be less important than its level relative to feed costs.  One measure 
of this relationship is known as the milk-to-feed price ratio, which represents the amount of feed that 
one pound of milk can buy. The annual average for this ratio of 1.52 in 2012 was the lowest recorded 
since this ratio was first reported in 1985. The highest annual average this ratio has reached since 1985 
was 3.64 in 1987. Since this ratio reached 3.24 in 2005, it has not exceeded 3.0. The annual average of 
2.54 for 2014 was the highest this ratio has been since it was 2.81 in 2007. This ratio dropped 16% 
from 2017 to an annual average of 2.04 during 2018. The annual average has not been lower than this 
level since 2013. An increase in feed costs also has a negative impact on the beef industry.  The fol-
lowing table demonstrates the annual volatility and the low values of this ratio recently:

•  While the number of cows in the U.S. herd and the production of milk per cow directly influence the 
supply of milk, the price for milk is also influenced by very volatile international demand for milk 
products.   

•  The all-time high value (annual average) for a milk cow was $1,993 during 2015. Since then, this 

annual average value has steadily declined to $1,358 during 2018. The 2018 value represents a 32%, 
or $635, decrease from the 2015 high.   

•  The industry data referred to above is compiled from USDA databases. Additionally, the value of 

newborn bull calves had risen to the unusually high level of approximately $300 to $400 during 2015 
but has declined to very little presently, depending on region.  

•  Given our focus on the dairy and beef industries, the volatile market conditions and the resulting finan-
cial insecurities of our primary end users are risks to our ability to maintain and grow sales at a profita-
ble level. These factors also heighten the challenge of selling premium-priced animal health products 
(such as Tri-Shield First Defense and Re-Tain™) into the dairy market. 

Product development risks:  The development of new products is subject to financial, scientific, regulatory, and 
market risks. Our current business growth strategy relies heavily on the development of Re-Tain™, our new product to 
treat subclinical mastitis, which has required (and will continue to require) a substantial investment of capital resources 
and personnel. Our efforts will be subject to inspection and approval by the FDA. There is no assurance whether or when 

14 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
   
 
 
 
 
 
 
 
 
 
 
ImmuCell Corporation 

we will obtain all of the data necessary to support regulatory approval for this product. 

Risks associated with our funding strategy for Re-Tain™:  Producing our pharmaceutical-grade Nisin at commer-
cial-scale is the most critical action in front of us on our path to U.S. regulatory approval for this product. Having com-
pleted construction of the production facility described elsewhere in this report at a cost of approximately $20.8 million, 
we will continue to incur product development expenses to operate this facility. We do not know whether we will receive 
the necessary regulatory approvals to manufacture and sell the product, or whether the product will achieve market ac-
ceptance and profitability. The additional debt we incurred to fund this project will significantly increase our debt service 
costs going forward. These loans are subject to certain financial covenants. Absent sufficient sales of Re-Tain™ at a 
profitable gross margin, we would be required to fund all debt service costs from sales of the First Defense product 
line, which would reduce, and could eliminate, our expected profitability going forward and significantly reduce our 
cash flows. As discussed elsewhere in this report, we may incur additional capital costs to construct our own aseptic 
filling capability for Re-Tain™ which would magnify the risks detailed in this paragraph. 

Uncertainty of market size and product sales estimates for Re-Tain™:  Estimating the size of the market for any 

new product is subject to numerous uncertainties.  Some of the uncertainties surrounding our product include market 
acceptance, the development of the subclinical mastitis treatment market, the effect of a premium selling price on 
market penetration, competition from existing products sold by substantially larger competitors, the risk of competition from 
other new products, cost of manufacture and integration of milk from treated cows with susceptible cheese starter 
cultures. Given what we believe to be reasonable assumptions, we estimate that the market potential for first year sales of 
our new product could be approximately $5.8 million and could grow to approximately $36.1 million during the fifth 
year after market launch. The amount of sales that we can capture from this estimated market potential and the timing of 
when this can be achieved is very difficult to know, and the actual size of the market for our new product may differ 
materially from our estimates (up or down). We expect the Drug Substance production facility that we have constructed 
to have production capacity to meet approximately $10 million in annual sales. Our new facility is designed to have 
enough room to add a second fermentation and recovery portion of the production line to be purchased and installed at 
the cost of approximately $7 million to effectively double production output. However, we are considering the strategic 
alternative of using this available space to perform the final formulation, aseptic filling and final packaging services 
in-house. 

Exposure to debt service obligations and debt covenants: Rising interest rates could negatively affect our 

operating results due to the large portion of our borrowings that bear interest at variable rates (which were not 
effectively converted to fixed rate obligations through interest rate swaps) as well as by increasing dairy farmers’ 
operating costs and thus putting further financial pressure on an already stressed business sector. Based on the terms of 
our bank debt agreements effective as of December 31, 2018, we are required by bank debt covenant to maintain at 
least $2 million of otherwise unrestricted cash, cash equivalents and short-term investments. This requirement 
effectively reduces the availability of our liquid assets for operational needs and creates a risk of non-compliance. 

Competition from others:  Many of our competitors are significantly larger and more diversified in the relevant 

markets than we are and have substantially greater financial, marketing, manufacturing and human resources and more 
extensive product development capabilities than we do, including greater ability to withstand adverse economic or 
market conditions and declining revenues and/or profitability. Elanco, Merck and Zoetis, among other companies, sell 
product line in preventing scours in newborn calves. The scours 
products that compete directly with the First Defense
product sold by Zoetis sells for approximately half the price of our product, but it does not have an E. coli claim (which 
ours does).  The market for the treatment of mastitis in dairy cows is highly competitive, and presently is dominated by 
large companies such as Boehringer Ingelheim, Merck and Zoetis. The mastitis products sold by these large companies 
are well established in the market and are priced lower than what we expect for our product, but all of them involve 
traditional antibiotics and are sold subject to a requirement to discard milk during and for a period of time after 
treatment. There is no assurance that our product will compete successfully in this market.  We may not be aware of 
other companies that compete with us or intend to compete with us in the future.

Access to raw materials and contract manufacturing services:  Our objective is to maintain more than one source 
of supply for the components used to manufacture and test our products that we obtain from third parties. However, there 
is a risk that we could have difficulty in efficiently acquiring essential supplies. We have significantly increased the 
number of farms from which we purchase colostrum. The loss of farms from which we buy raw material for the First 
Defense

product line could make it difficult for us to produce enough inventory to meet customer demand. The

product line are not readily available from 

specific antibodies that we purify from colostrum for the First Defense
other sources. We are and will be dependent on our manufacturing facilities and operations in Portland for the 
product line and Nisin. We are and will be dependent on Plas-Pak Industries, Inc. 
production of the First Defense
(now owned by Nordson Corporation) for the supply of the syringes used for our gel tube format of Dual-Force™ 
and Re-Tain™. The supply contract covering the mastitis syringes has 
First Defense
been extended to January 1, 2024. We expect to be dependent on a contract with Norbrook for the final formulation, 
aseptic filling and final packaging of our Nisin Drug Substance into Drug Product unless we find an alternative 
contractor or invest to perform these services in-house. Norbrook may have the right to terminate the agreement in 
December 2019 and charge us a $100,000 termination fee if (as we anticipate) we do not receive FDA approval for 
Re-Tain™ by that date. We have been and are currently negotiating certain contract modifications and a term 
extension with Norbrook. There is no assurance that this negotiation will be successful for us. Due to the potential loss 
of this contract as discussed elsewhere in this report, we are evaluating alternative sources for these services (including 
a potential investment in our own facility to perform these services internally) for potential use post-approval, but 
given the requirement that such a facility be inspected and approved by the FDA, it could be costly and 
time-consuming to find and qualify an adequate alternative source for these services. Also, our potential alternative 
options for these services are narrowed considerably because our product cannot be formulated or filled in a facility 
that also processes traditional antibiotics (i.e. beta lactams). Not many potential sites meet this requirement. There can 
be no assurance that we would be able to identify and reach contractual terms with a duly licensed/certified provider of 
these services, as applicable, if our relationship with Norbrook were to be terminated or, if we were able to do so, how 
quickly that could occur and on what terms. Such a shift could result in significant production interruptions, delay in 
market launch, significantly increased cost of goods sold and reduced margins, the effects of which could be material and 
adverse to us. Any significant damage to or other disruption in the services at any of these third-party facilities (including 
due to regulatory non-compliance) could adversely affect the production of inventory and result in significant added 
expenses and potential loss of future sales. 

Production Capacity Constraints:  The failure to meet market demand for our products discussed elsewhere in 
product line requires ongoing 

this report is a risk to our business. Our plan to continue to expand the First Defense
review of equipment capacity and utilization across the manufacturing value stream at the 56 Evergreen Drive facility 
as well as assessment of functional obsolescence and reliability of equipment. It is anticipated that we will need to add a 
product line over the next two or three years at a cost of 
third freeze dryer to the equipment train for the First Defense
approximately $1-$2 million in order to meet customer demand. Our current two freeze dryers are functioning at a 
utilization rate of approximately 85%. Additional liquid processing equipment may be required at a cost of 
approximately $1-$2 million. There is a risk that we will not be able to achieve our production capacity growth 
objectives on a timely basis. 

 

 

Small size; dependence on key personnel:  We are a small company with 51 employees (including 4 part-time 

employees).  As such, we rely on certain key employees to support multiple operational functions, with limited 
redundancy in capacity.  The loss of any of these key employees could adversely affect our operations until a qualified 
replacement is hired and trained.  Our competitive position will be highly influenced by our ability to attract and retain 
key scientific, manufacturing, managerial and sales and marketing personnel, to develop proprietary technologies and 
products, to obtain USDA or FDA approval for new products, to maintain regulatory compliance with current products 
and to continue to profitably sell our current products. We continue to monitor our network of independent distributors to 
maintain our competitive position. 

Failure to protect intellectual property: In some cases, we have chosen (and may choose in the future) not to seek 
patent protection for certain products or processes.  Instead, we have sought (and may seek in the future) to maintain the 
confidentiality of any relevant proprietary technology through operational safeguards and contractual  agreements. 
Reliance upon trade secret, rather than patent, protection may cause us to be vulnerable to competitors who successfully 
replicate our manufacturing techniques and processes.  Additionally, there can be no assurance that others may not 
independently develop similar trade secrets or technology or obtain access to our unpatented trade secrets or proprietary 
technology.  Other companies may have filed patent applications and may have been issued patents involving products 
or technologies potentially useful to us or necessary for us to commercialize our products or achieve our business goals. 
There can be no assurance that we will be able to obtain licenses to such patents on terms that are acceptable.  There is 
also a risk that competitors could challenge the claims in patents that have been issued to us.

Cost burdens of our reporting obligations as a public company:  Operating a public company involves substantial 
costs to comply with reporting obligations under federal securities laws and the provisions of the Sarbanes-Oxley Act of 
2002.   

Exposure to risks associated with the financial downturn and economic instability: Positive indications about the 

health of the U.S. economy could prove temporary, and a downturn could occur. Some observers believe that the 
housing market remains problematic for the overall U.S. economy, the United States has taken on too much national 
debt and the equity markets are overvalued. Interest rates are trending higher, which could adversely affect us and the 
general economy and our customers. This extraordinary period of instability in the U.S. economy and the financial 
markets has been troubling for many Americans and businesses. The dairy market is presently under extreme economic 
pressure, causing many of our customers to lose money or only earn minimal profits. A small percentage reduction in 
the export of dairy products results in a significant drop in the domestic price of milk. A combination of the conditions, 
trends and concerns summarized above could have a corresponding negative effect on our business and operations, 
including the demand for our products in the U.S. market and our ability to penetrate or maintain a profitable presence in 
international markets.   

Bovine diseases:  The potential for epidemics of bovine diseases such as Foot and Mouth Disease, Bovine 

Tuberculosis, Brucellosis and Bovine Spongiform Encephalopathy (BSE) presents a risk to us and our customers. 
Documented cases of BSE in the United States have led to an overall tightening of regulations pertaining to ingredients 
of animal origin, especially bovine. The First Defense

could affect the First Defense

product line, although presently we do not anticipate that this will be the case.

Biological terrorism:  The threat of biological terrorism is a risk to both the economic health of our customers and 

our ability to economically acquire and collect good quality raw material from our contract farms. Any act of wide-
spread bioterrorism against the dairy industry could adversely affect our operations.   

Certain provisions might discourage, delay or prevent a change in control of our Company or changes in our 
management: Provisions of our certificate of incorporation, our bylaws, our Common Stock Rights Plan or Delaware 
law may discourage, delay or prevent a merger, acquisition or other change in control that stockholders may consider 
favorable, including transactions in which stockholders might otherwise receive a premium for their shares of our com-
mon stock. These provisions may also prevent or frustrate attempts by our stockholders to replace or remove our man-
agement. These provisions include: 

• 

• 

• 

limitations on the removal of directors; advance notice requirements for stockholder proposals and 
nominations; 

the ability of our Board of Directors to alter or repeal our bylaws; 

the ability of our Board of Directors to refuse to redeem rights issued under our Common Stock Rights 
Plan or otherwise to limit or suspend its operation that would work to dilute the stock ownership of a 
potential hostile acquirer, likely preventing acquisitions that have not been approved by our Board of 
Directors; and 

•  Section 203 of the Delaware General Corporation Law, which prohibits a publicly-held Delaware cor-
poration from engaging in a business combination with an interested stockholder (generally defined as 
a person which together with its affiliates owns, or within the last three years has owned, 15% of our 
voting stock, for a period of three years after the date of the transaction in which the person became an 
interested stockholder) unless the business combination is approved in a prescribed manner. 

The existence of the foregoing provisions and anti-takeover measures could depress the trading price of our 
common stock or limit the price that investors might be willing to pay in the future for shares of our common stock. They 
could also deter potential acquirers of our Company, thereby reducing the likelihood of obtaining a premium for our 
common stock in an acquisition. 

Stock market valuation and liquidity: Our common stock trades on The Nasdaq Stock Market (Nasdaq: ICCC). 

Our average daily trading volume (although it has increased recently) is lower than the volume for most other companies 

17 

 
 
ImmuCell Corporation 

and the bid/ask stock price spread can be larger and prices can be volatile, which could result in investors facing diffi-
culty selling their stock for proceeds that they may expect or desire. There are companies in the animal health sector with 
market capitalization values that greatly exceed our current market capitalization of approximately $37,982,000 as of 
March 18, 2019.  We currently (for the year ended December 31, 2018) have annual product sales of approximately 
$11,000,000.  Before gross margin from the sale of new products is achieved, our market capitalization may be heavily 
dependent on the perceived potential for growth from our products under development. 

No expectation to pay any dividends or repurchase stock for the foreseeable future:  We do not anticipate paying 
any dividends to, or repurchasing stock from, our stockholders for the foreseeable future. Instead, we expect to use cash 
to fund product development costs and investments in our facility and production equipment, and to increase our work-
ing capital and to reduce debt. Stockholders must be prepared to rely on sales of their common stock after price appre-
ciation to earn an investment return, which may never occur.  Any determination to pay dividends in the future will be 
made at the discretion of our Board of Directors and will depend on our financial condition, results of operations, con-
tractual restrictions, restrictions imposed by applicable laws, current and anticipated needs for liquidity and other factors 
our Board of Directors deems relevant. 

Possible dilution: We may need again to access the capital markets and issue additional common stock in order to 

fund our growth objectives, as described elsewhere in this report. Such issuances could have a dilutive effect on our 
existing stockholders.

ITEM 2 — PROPERTIES 

We own a 35,000 square foot (approximately) building at 56 Evergreen Drive in Portland, Maine. We currently 
use this space for substantially all of our office, laboratory and manufacturing needs. When we originally purchased 
this building in 1993, its size was 15,000 square feet, including 5,000 square feet of unfinished space on the second 
floor. In 2001, we completed a construction project that added approximately 5,200 square feet of new manufacturing 
space on the first floor and approximately 4,100 square feet of storage space on the second floor. In 2007, we built out 
the 5,000 square feet of unfinished space on the second floor into usable office space. After moving first floor offices 
into this new space on the second floor, we modified and expanded the laboratory space on the first floor and added 
approximately 2,500 additional square feet of storage space on the second floor. During 2009, we added 350 square 
feet of cold storage space connected to our first floor production area and added an additional 600 square feet to the 
second floor storage area. During the first quarter of 2015, we completed construction of a two-story addition 
connected to our facility to provide us with approximately 7,100 additional square feet for cold storage, production 
and warehouse space for our operations. 

During the fourth quarter of 2015, we exercised an option to acquire land at 33 Caddie Lane in Portland, Maine 
which is nearby to our facility at 56 Evergreen Drive, on which we initiated construction of our production facility for 
purified Nisin during the third quarter of 2016. During the fourth quarter of 2017, we obtained a certificate of 
occupancy from the City of Portland for our 16,202 square foot (9,803 on the first floor and 6,399 on the second floor) 
Drug Substance production facility. 

During 2016, we rented approximately 3,266 square feet in Minnesota on a short-term basis, where we 
formulated our gel tube delivery format of First Defense Technology® and certain private label products. This lease 
expired during the first quarter of 2017, and we no longer utilize this space. The manufacturing of this product line was 
transferred to the Portland facility during the first quarter of 2017. 

During the first quarter of 2017, we purchased a 4,114 square foot facility adjacent to the Drug Substance 
production facility. We are using this warehouse space primarily for storage of inventory, materials and equipment. 

Previously, we rented approximately 640 square feet of office and warehouse space in New York to support our 
farm operations. During the first quarter of 2017, we exited this property and entered into a renewable, two-year lease 
for approximately 1,350 square feet of office, warehouse and garage space nearby. This lease has been extended 
through February of 2021.

ITEM 7 — MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 

RESULTS OF OPERATIONS 

The following discussion and analysis of our financial condition and results of operations should be read 
together with our financial statements and the related notes and other financial information included in Part II, Item 8 
— “Financial Statements and Supplementary Data” of this Annual Report on Form 10-K. Some of the information 
contained in this discussion and analysis or set forth elsewhere in this Annual Report, including information with 
respect to our plans and strategy for our business and related financing, includes forward-looking statements that 
involve risks and uncertainties. One should review Part I, Item 1A — “Risk Factors” of this Annual Report for a 
discussion of important factors that could cause actual results to differ materially from the results described in or 
implied by the forward-looking statements contained in the following discussion and analysis. 

Liquidity and Capital Resources 

We have funded most of our operations principally from our gross margin on product sales and equity and debt 

financings. We were profitable during the six-month period ended December 31, 2014 and during the years ended 
December 31, 2015 and 2016 and during the unaudited nine-month period ended September 30, 2017. The table below

Net cash (used for) operating activities amounted to ($373,000) during the year ended December 31, 2018 in 

contrast to net cash provided by operating activities of $1.2 million during the year ended December 31, 2017. Cash 
paid for capital expenditures totaled $2 million during the year ended December 31, 2018 in comparison to capital 
expenditures of $17.8 million during the year ended December 31, 2017 reflecting the completion of our Drug Sub-
stance production facility. We are required to make a statement about the adequacy of our capital resources. We believe 
we have sufficient capital resources to continue operations for at least twelve months from the date of this filing. 

During 2017 and 2016, we raised gross proceeds of approximately $13.5 million (net proceeds were 

approximately $12.2 million) from four different common equity transactions. During the first and fourth quarters of 
2016, we issued an aggregate of approximately 1.8 million shares of common stock at $5.25 per share, raising net 
proceeds of approximately $8.5 million in two separate transactions. During the third quarter of 2017, we issued 
200,000 shares of common stock at $5.25 per share, raising net proceeds of just over $1.0 million. During the fourth 
quarter of 2017, we issued 417,807 shares of common stock at $7.30 per share, raising net proceeds of approximately 
$2.7 million. No additional equity transactions were completed during 2018. 

During 2017 and 2016, we secured debt financing from TDBank N.A. in the form of three different facilities ag-
gregating approximately $6.8 million. This debt is in addition to two mortgage loans entered into during 2010 and 2015 
that aggregated $3.5 million at inception, also with TDBank N.A. As of December 31, 2018, $9.4 million was out-
standing under these five facilities. We also have a $500,000 line of credit with TDBank N.A. that is available as needed 
through May 31, 2020 and subject to extension by the bank after that date. As of December 31, 2018, $500,000 was 
outstanding under the line of credit. These credit facilities are subject to certain restrictions and financial covenants and 
are secured by substantially all of our assets, including our facility at 56 Evergreen Drive in Portland, which was inde-
pendently appraised at $4.2 million in connection with the 2015 financing. We are required by bank debt covenant to 
maintain at least $2 million of otherwise unrestricted cash, cash equivalents and short-term investments, thus reducing 
the effective availability of our liquid assets for operational needs by that amount. We are negotiating with the bank to 
return to an acceptable covenant based on income statement performance in order to regain access to these liquid assets. 
We were in compliance with all applicable covenants as of December 31, 2018. No additional debt facilities were en-
tered into during 2018. 

During the third quarter of 2016, we initiated construction of our Drug Substance production facility. We 
completed construction of the building during the fourth quarter of 2017 and began depreciating these construction 
costs at that time. We began equipment installation during the third quarter of 2017 and began depreciating these costs 
when the equipment was placed into service for its intended purpose (which is to produce Nisin) during the third 
quarter of 2018. We anticipate that depreciation expense, while not affecting our cash flows from operations, will 
result in net operating losses until product sales increase sufficiently to offset these non-cash expenses. Going forward, 
repayments of the indebtedness incurred to acquire these assets will reduce our cash flows from financing activities. 
The following table details the amount and timing of this investment on a cash-paid basis:

  (1)  An additional $1,041,000 was paid during the year ended December 31, 2014 to bring the total cost of this project to 

$1,955,000. 

  (2)  This amount is net of a credit of approximately $61,000 for a returned fixed asset acquired during 2016. 

As of January 1, 2019, we had additional authorization from our Board of Directors to invest up to 

approximately $500,000 through December 31, 2019 in routine and necessary capital expenditures. We believe that 
our cash, together with gross margin to be earned from ongoing product sales and available bank debt, will be 
sufficient to meet our working capital and capital expenditure requirements and to finance our ongoing business 
operations for at least twelve months from the date of this filing.   

During the third quarter of 2016, the City of Portland approved a Tax Increment Financing (TIF) credit 
enhancement package that reduces the real estate taxes on our Drug Substance production facility by 65% over the 
eleven-year period beginning on July 1, 2017 and ending June 30, 2028 and by 30% during the twelve-month period 
ending June 30, 2029, at which time the rebate expires. During the second quarter of 2017, the TIF was approved by the 
Maine Department of Economic and Community Development. Based on the assessed value of $1.7 million as of April 
1, 2017, the TIF reduced our property taxes by approximately $22,000 during the twelve-month period ended June 30, 
2018 (the first year of the TIF benefit). Based on the assessed value of $4 million as of April 1, 2018, the TIF has 
reduced our property taxes by approximately $58,000 during the twelve-month period ending June 30, 2019 (the 
second year of the TIF benefit). The value of the tax savings will increase (decrease) in proportion to any increase 
(decrease) in the assessment of the building for city real estate tax purposes.   

Outlook 

The prolonged period of order backlog we experienced for our First Defense® product line (which began early 

in 2015 and extended through the middle of 2016) disrupted our normal product shipping patterns. In response, we 
completed investments necessary to increase our liquid processing capacity by 50% during the fourth quarter of 2015 
and our freeze drying capacity by 100% during the first quarter of 2016. With this expanded production capacity, we 
can now produce product with an annual sales value of approximately $18 million. The actual value of the production 
output will vary subject to product yields, selling price and product format mix. Since the third quarter of 2016 and 
through most of 2017, we had sufficient available inventory and were shipping in accordance with the current demand 
of our distributors. However, we quickly sold out of our initial launch quantities of Tri-Shield First Defense® soon 
after regulatory approval was obtained during the fourth quarter of 2017. Presently, we are only accepting purchase 
orders from customers to match available inventory, which requires a careful allocation of product supply directly to 
certain farms. Production of this new product format has not kept pace with demand primarily because of our inability 
to produce enough of the new, complex rotavirus vaccine that is used to immunize our source cows in this time frame. 
Current production improvements in our vaccine laboratory will allow us to immunize more source cows, but the 
increased supply of finished product will not be available for sale in a significant way until the second half of 2019. 
While this product shortage is a problem and has adversely impacted customer relations and resulted in lost sales, it is 
also a positive indication that the market is accepting our new product offering. During the first quarter of 2018, sales 
demand for Dual-Force™ First Defense® also exceeded available inventory, resulting in a backlog of orders worth 
approximately $901,000 as of March 31, 2018, which was filled during the second quarter of 2018. The estimated 
value of this backlog was calculated by multiplying the number of units for which customer orders had been received 
but were not shipped at the end of the period by the expected selling price. In order to produce more doses quickly to 
clear the 2015/2016 order backlog, we significantly increased the quantity of our supply of colostrum at the same time 

23 

 
 
 
 
 
 
 
 
ImmuCell Corporation 

that we were making the investments to increase our production capacity, discussed above. The 2018 backlog problem 
was largely caused by a reduction in the biological yield from this new colostrum supply. To address the inherent 
variability in our biological yields, among other process improvements, we have optimized the mix of early milk that 
is rich with antibodies and later milk that contains less antibodies but is required to run our production process. As we 
rebuild target inventory levels of Dual-Force™, we are confident that we will again consistently supply product to the 
market because of the improved production methods to increase yields and the enhanced manufacturing redundancies 
that we have implemented. Given the strength of what we are seeing for potential demand for the First Defense® 
product line in North America, we are making preliminary plans to further increase our liquid processing capacity by 
100% and our freeze drying capacity by 50%. This would require additional capital to be raised. Our very preliminary 
estimate of the cost of this investment is approximately $3 million. 

Results of Operations   

2018 Compared to 2017   

Product Sales 

Total product sales during the three-month period ended December 31, 2018 decreased by 6%, or $196,000, to 
$2,937,000, from $3,133,000 during the same period in 2017, with domestic sales increasing by 1%, or $29,000, and 
international sales decreasing by 35%, or $225,000, in comparison to the same period during 2017. Total product sales 
during the year ended December 31, 2018 increased by 5%, or $555,000, to $10,986,000 from $10,431,000 during the 
same period in 2017, with domestic sales increasing by 11%, or $933,000, and international sales decreasing by 21%, 
or $377,000, in comparison to 2017. Approximately 87% of our sales during 2018 were made in the domestic market. 
Sales of our core animal health products (excluding one product that was divested during 2017 and another that was 
divested during 2018) increased by 8%, or $821,000, during 2018 over 2017. As of December 31, 2018, we had orders 
worth approximately $393,000 that did not ship until the beginning of 2019 because of the holiday schedule and our 
restriction against shipping product that requires cold shipment over a weekend or holiday. 

The First Defense® product line continues to benefit from wide acceptance by dairy and beef producers as an 

effective tool to prevent scours (diarrhea) in newborn calves. Sales of the First Defense® product line aggregated 98% 
and 94% of our total product sales during the three-month periods ended December 31, 2018 and 2017, respectively. 
Sales of the First Defense® product line during the three-month period ended December 31, 2018 decreased by 3% in 
comparison to the same period during 2017, with domestic sales increasing by 3% and international sales decreasing 
by 29% in comparison to the same period during 2017. Sales of the First Defense® product line aggregated 97% and 
94% of our total product sales during the years ended December 31, 2018 and 2017, respectively. Sales of the First 
Defense® product line during the year ended December 31, 2018 increased by 9% in comparison to 2017, with 
domestic sales increasing by 13% and international sales decreasing by 13% in comparison to 2017. 

Going forward, we expect to only provide disclosures about sales of the First Defense® product line as a whole. 

However, to provide some insight into the new product launch, we are disclosing that sales of Tri-Shield® 
approximately $250,000, $236,000, $216,000, $252,000 and $442,000 during the fourth quarter of 2017, the first quarter 
of 2018, the second quarter of 2018, the third quarter of 2018 and the fourth quarter of 2018, respectively. We expect to 
 during the first quarter of 2019. By the third quarter of 2019, we expect 
sell approximately $795,000 worth of Tri-Shield
to be able to produce product with a sales value of approximately $1-$1.5 million per quarter. As these projections 
suggest, we are satisfied that we are successfully addressing the vaccine production and biological yield issues 
pertaining to the manufacture of this new product.



During 2015, we implemented an increase of approximately 10% to the selling price of the gel tube format of 
First Defense Technology® (which is now being marketed with USDA claims as Dual-Force™ First Defense®). 
During the middle of 2016, we implemented a price increase of approximately 5% for First Defense®. Effective in 
December of 2018, we implemented an 11% increase for Tri-Shield First Defense®. Effective January 1, 2019, we 
implemented a 2% increase to the bivalent formats of the First Defense® product line. Going forward, we anticipate 
making more frequent (but not more than annual) price increases in line with current rates of inflation. 

Sales of products other than the First Defense® product line decreased by $116,000 during the three-month 

period ended December 31, 2018 in comparison to the same period during 2017. Sales of these other products 

24 

 
 
ImmuCell Corporation 

decreased by $294,000 during the year ended December 31, 2018 in comparison to 2017. Sales of these other products 
aggregated 2% and 6% of our total product sales during the three-month periods ended December 31, 2018 and 2017, 
and 3% and 6% of our total product sales during the years ended December 31, 2018 and 2017, respectively. We 
acquired several other private label products (our second leading source of product sales during 2018) in connection 
with our January 2016 acquisition of certain gel formulation technology. During the fourth quarter of 2016, we shut 
down the manufacturing site in Minnesota that had been used to produce these products and moved these operations to 
our Portland facility. We are realizing reduced labor and overhead expenses and benefiting from certain other 
operating efficiencies as a result of this consolidation. We sell our own California Mastitis Test (CMT) (our third 
leading source of product sales during 2018), which is used to detect somatic cell counts in milk. We have made and 
sold bulk reagents for Isolate™ (our third leading source of product sales during 2017), which is a drinking water test 
that is sold by our distributor in the United Kingdom. Sales of this product amounted to $24,000 and $193,000 during 
the years ended December 31, 2018 and 2017, respectively. Because this product is non-core to our strategic focus, we 
sold the underlying cell line assets and intellectual property to a distributor during the third quarter of 2018 for 
$700,000. We made one final sale of this product to this distributor during the first quarter of 2019. We have retained 
the rights to all animal health, diagnostic, feed and nutritional applications of this technology. Sales of our Nisin-based 
topical wipes (our second leading source of animal health product sales prior to 2017) aggregated approximately 
$97,000 during the year ended December 31, 2017 (all recorded during the first quarter of 2017). The topical wipes 
product line contributed very little to our profits and required a significant portion of our production and storage 
capacity. Because we believed that the sales growth potential for this product line was limited, we discontinued the 
production and sale of this product line during the first quarter of 2017.   

Gross Margin

The gross margin as a percentage of product sales was 48% and 39% during the three-month periods ended 

December 31, 2018 and 2017, respectively. Several events occurred during the fourth quarter of 2017 that drove our 
costs of goods sold higher than normal. Costs associated with the initial batches of Tri-Shield First Defense® yielded 
fewer doses at a higher cost than we expected. Two batches of the First Defense® product line did not meet our 
stringent quality standards. One had to be discarded, and the other has to be re-processed. In addition, several lots 
yielded fewer doses than normal due to biological yield factors. We believe we understand the cause of this biological 
variance and have corrected for it. The improved margin during the fourth quarter of 2018 was achieved consistently 
for the full year.

The gross margin as a percentage of product sales was 47% and 50% during the years ended December 31, 2018 
and 2017, respectively. This compares to gross margin percentages of 57% and 61% during the years ended December 
31, 2016 and 2015, respectively. The gross margin percentage for the legacy formats of the First Defense® product line 
was in line with prior years. The new gel formats of our product are more expensive and contribute a lower gross 
margin. However, these new formats are creating sales growth for us, and we are focused on increasing total gross 
margin, even if that is accomplished with a lower gross margin percentage of sales. As we evaluate our product costs 
and selling price, it is one of our goals to continue to achieve a gross margin (before related depreciation expenses) as a 
percentage of total sales approaching 50%. We have achieved this annual objective since 2009, but the 2018 result is 
lower than prior years. A number of factors account for the variability in our costs, resulting in some fluctuations in 

25 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
ImmuCell Corporation 

gross margin percentages from quarter to quarter. The gross margin on the First Defense® product line is affected by 
biological yields from our raw material, which do vary over time. Just as our customers’ cows respond differently to 
commercial dam-level vaccines depending on time of year and immune competency, our source cows have similar 
biological variances in response to our proprietary vaccine. The value of our First Defense® product line is that we 
compensate for that variability by standardizing each dose of finished product. This impacts our costs of goods sold but 
insures that every calf is equally protected, which is something that dam-level commercial scours vaccines cannot offer. 
Like most U.S. manufacturers, we have also been experiencing increases in the cost of raw materials that we purchase. 
Our costs have increased due to increased labor costs and other expenses associated with our efforts to sustain 
compliance with current Good Manufacturing Practice (cGMP) regulations in our production processes. Over time, we 
have been able to minimize the impact of cost increases by implementing yield improvements. 

Product Development Expenses 

Product development expenses increased by 72%, or $1,470,000, to $3,517,000 during the year ended 
December 31, 2018 in comparison to $2,047,000 during the same period in 2017. Product development expenses 
aggregated 32% and 20% of product sales during the years ended December 31, 2018 and 2017, respectively. It is 
important to note that these figures include $783,000 and $176,000 of non-cash depreciation expense and $148,000 
and $100,000 of non-cash, stock-based compensation expense during the years ended December 31, 2018 and 2017, 
respectively. Excluding these non-cash expenses, cash-based product development expenses increased by 46%, or 
$815,000, to $2,585,000 during the year ended December 31, 2018 in comparison to $1,771,000 during the same 
period in 2017. The majority of our product development spending is focused on the development of Re-Tain™, our 
purified Nisin treatment for subclinical mastitis in lactating dairy cows. 

Sales and Marketing Expenses 

Sales and marketing expenses increased by approximately 10%, or $192,000, to $2,085,000 during the year 
ended December 31, 2018 in comparison to $1,893,000 during the same period in 2017, amounting to 19% and 18% of 
product sales during the years ended December 31, 2018 and 2017, respectively. We continue to leverage the efforts of 
our small sales force by using animal health distributors. These expenses have increased due principally to a strategic 
decision to invest more to support sales of the First Defense® product line. Our current budgetary objective in 2019 is 
to invest less than 20% of product sales in sales and marketing expenses on an annual basis. This ratio can come down 
incrementally as sales grow. 

Administrative Expenses 

Administrative expenses increased by approximately 14%, or $214,000, to $1,739,000 during the year ended 
December 31, 2018 in comparison to $1,525,000 during the same period in 2017. Administrative expenses include 
$70,000 and $76,000 of non-cash depreciation expense and $148,000 and $100,000 of non-cash, stock-based 
compensation expense during the years ended December 31, 2018 and 2017, respectively. We strive to be efficient with 
these expenses while funding costs associated with complying with the Sarbanes-Oxley Act of 2002 and all the legal, 
audit and other costs associated with being a publicly-held company. Prior to 2014, we had limited our investment in 
investor relations spending. Beginning in the second quarter of 2014, we initiated an investment in a more active 
investor relations program while continuing to provide full disclosure of the status of our business and financial 
condition in three quarterly reports and one annual report each year, as well as in Current Reports on Form 8-K when 
legally required or deemed appropriate by management. Additional information about us is available in our annual 
Proxy Statement. All of these reports are filed with the SEC and are available on-line or upon request to the Company.   

Gain on Sale of Assets 

During the third quarter of 2018, we sold the assets underlying our water diagnostic product for $700,000. This sale 

of assets was recognized as an operating activity at that time. An upfront payment of $250,000 was received upon 
closing, a second payment of $250,000 is due during the third quarter of 2019 and a third payment of $200,000 is due 
during the fourth quarter of 2019.

Net Operating Loss 

Our net operating loss during the year ended December 31, 2018 of $1,447,000 was $1,204,000 larger than a net 
operating loss of $243,000 during the year ended December 31, 2017. The net operating loss included $1,537,000 and 
$920,000 of non-cash depreciation, amortization and deferred finance cost expenses and $344,000 and $200,000 of 
non-cash, stock-based compensation expense during the years ended December 31, 2018 and 2017, respectively. This 
increase in our net operating loss was driven primarily by an increase in cost of goods sold (on similar sales volume) 
and an increase in product development expenses (in addition to the increase in the non-cash expenses discussed 
above). 

Other expenses, net   

Other expenses, net, aggregated $413,000 and $196,000 during the years ended December 31, 2018 and 2017, 
respectively. Interest expense (including amortization of debt issuance costs of approximately $17,000 and $15,000 
during the years ended December 31, 2018 and 2017, respectively) increased by approximately 96%, or $209,000, to 
$428,000 during the year ended December 31, 2018 in comparison to $219,000 during the same period in 2017, due to 
higher levels of outstanding debt at modestly higher interest rates on the variable rate credit facilities. Assuming an 
interest rate of 5.0% on our variable rate notes, we estimate that interest expense would be approximately $460,000 
during the year ending December 31, 2019. Actual interest expense will be charged at 2.25% over the one-month 
LIBOR. The one-month LIBOR was 2.51% as December 31, 2018. Interest income decreased by approximately 15%, 
or $3,000, to $14,000 during the year ended December 31, 2018, in comparison to $17,000 during 2017. Less interest 
income was earned during the 2018 periods because we had less cash and investments on hand and because these 
funds were held in more liquid investments (that earn a lower rate of interest) during the current periods in order to 
fund our capital expenditure requirements. 

Loss Before Income Taxes and Net Loss   

Our loss before income taxes of $1,860,000 during the year ended December 31, 2018 was $1,422,000 larger 

than our loss before income taxes of $438,000 during the year ended December 31, 2017. We recorded an income tax 
expense (benefit) of 25% and (62%) of the loss before income taxes during the years ended December 31, 2018 and 
2017, respectively. On December 22, 2017, the Tax Cuts and Jobs Act was signed into law. This legislation makes 
significant changes in the U.S. tax laws, including a reduction in the corporate tax rates, changes to net operating loss 
carryforwards and carrybacks, and a repeal of the corporate alternative minimum tax. The legislation reduced the U.S. 
corporate tax rate from the current rate of 34% to 21%. Our net loss of $2,322,000, or $0.42 per share, during the year 
ended December 31, 2018 compares to a net loss of $168,000, or $0.03 per share, during the year ended December 31, 
2017. 

During the second quarter of 2018, we assessed our historical and near-term future profitability and determined 

the need to record non-cash income tax expense of approximately $563,000 to create a full valuation allowance 
against our net deferred tax assets (which consist largely of net operating loss carryforwards and federal and state tax 
credits). Should future profitability be realized at an adequate level, we will be able to realize these deferred tax assets to 
offset future taxable income before they expire. However, we do not believe that will be soon enough to avoid the need 
for this valuation allowance at present, based on applicable current accounting standards and practices. Therefore, 
because we had incurred a net loss for three consecutive quarters and anticipated additional net losses for some period 
going forward before returning to profitability, it was determined, based on such accounting standards and practices, that 
this valuation allowance was necessary. We will continue to assess the need for the valuation allowance at each quarter 
and, in the event that actual results differ from these estimates or we adjust these estimates in future periods, we may need 
to adjust our valuation allowance. 

During the year ended December 31, 2018, our loss before income taxes of $1,860,000 included non-cash 

depreciation, amortization, stock-based compensation and deferred finance cost expenses of $1,882,000. In 
comparison, our loss before income taxes of $438,000 during the year ended December 31, 2017 included non-cash 
depreciation, amortization, stock-based compensation and deferred finance cost expenses of $1,120,000. We began 
depreciating our Drug Substance production facility during the fourth quarter of 2017, and we began depreciating the 
related production equipment during the third quarter of 2018. For tax return purposes only, our depreciation expense 
for the Drug Substance production facility and equipment was approximately $9,200,000 and $1,500,000 for the years 

27 

 
 
ImmuCell Corporation 

ended December 31, 2018 and 2017, respectively. This significant increase was largely related to accelerated 
depreciation allowed for tax purposes for our Drug Substance production facility investment. This increased our net 
operating loss carryforward to $11,800,000 as of December 31, 2018 from $1,700,000 as of December 31, 2017, 
which will be available to offset future taxable income. Our preliminary estimate of depreciation expense for books for 
the year ending December 31, 2019 is approximately $2,300,000. This figure is a preliminary estimate only and actual 
depreciation expense will vary from this estimate. This depreciation expense (that is far larger than what we have 
incurred historically) may cause, in part, a net loss for the year ending December 31, 2019. We believe it will be 
important to consider our net cash (used for) provided by operating activities from our Statements of Cash Flows (see 
page F-5 of the accompanying financial statements) to assess the cash generating ability of our operations going 
forward. Net cash (used for) provided by operating activities (which does not include investing or financing activities) 
was ($373,000) and $1,176,000 during the years ended December 31, 2018 and 2017, respectively. Given our 
increased level of outstanding bank debt, it is also important to consider the amount of our debt principal repayments that 
is disclosed as part of our net cash provided by financing activities from our Statements of Cash Flows (see page F-5 of the 
accompanying financial statements).   

Critical Accounting Policies 

The financial statements are presented on the basis of accounting principles that are generally accepted in the 

United States. All professional accounting standards that were effective and applicable to us as of December 31, 2018 
have been taken into consideration in preparing the financial statements. The preparation of financial statements 
requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and 
expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, 
including those related to revenue recognition, income taxes, contingencies and the useful lives and carrying values of 
intangible and long lived assets. We base our estimates on historical experience and on various other assumptions that 
we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the 
carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from 
these estimates under different assumptions or conditions. We have chosen to highlight certain policies that we 
consider critical to the operations of our business and understanding our financial statements. 

We sell products that provide Immediate Immunity™ to newborn dairy and beef cattle. We recognize revenue 
in accordance with the five step model in ASC 606.  These include i) identification of the contract with the customer, ii) 
identification of the performance obligations in the contract, iii) determination of the transaction price, iv) allocation 
of the transaction price to the separate performance obligations in the contract and v) recognition of revenue associated 
with performance obligations as they are satisfied. We recognize revenue at the time of shipment (including to dis-
tributors) for substantially all products, as title and risk of loss pass to the customer on delivery to the common carrier 
after concluding that collectability is reasonably assured. We do not bill for or collect sales tax because our sales are 
generally made to distributors and thus our sales to them are not subject to sales tax. We generally have experienced an 
immaterial amount of product returns. 

Inventory includes raw materials, work-in-process and finished goods and is recorded at the lower of cost, on the 
first-in, first-out method, or net realizable value (determined as the estimated selling price in the normal course of busi-
ness, less reasonably predictable costs of completion, disposal and transportation). Work-in-process and finished goods 
inventories include materials, labor and manufacturing overhead. 

ITEM 7A — QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

We believe that neither inflation nor interest rates nor currency exchange rates have had a significant effect on 
our revenues and expenses. However, future increases in inflation or interest rates or the value of the U.S. dollar could 
affect our customers and the demand for our products. We hope to increase the level of our future sales of products 
outside the United States. The cost of our products to international customers could be affected by currency 
fluctuations. The decline of the U.S. dollar against other currencies could make our products less expensive to 
international customers. Conversely, a stronger U.S. dollar could make our products more costly for international 
customers. During 2010, we hedged our interest rate exposure to a $1,000,000 mortgage with an interest rate swap 
agreement that effectively converted a floating interest rate to the fixed rate of 6.04%. During 2015, we hedged our 
interest rate exposure to a $2,500,000 mortgage with an interest rate swap agreement that effectively converted a 
floating interest rate to the fixed rate of 4.38%. We had outstanding debt totaling approximately $7,084,000 at 

28

December 31, 2018 (including a $500,000 outstanding balance on our line of credit) that bears interest at variable rates 
and is not subject to interest rate swaps.

ITEM 9A — CONTROLS AND PROCEDURES 

Disclosure Controls and Procedures. Our management, with the participation of the individual who serves as 

our principal executive and principal financial officer, evaluated the effectiveness of our disclosure controls and 
procedures as of December 31, 2018. Based on this evaluation, that officer concluded that our disclosure controls and 
procedures were effective as of that date. Disclosure controls and procedures are designed to ensure that information 
required to be disclosed by us in the reports that we file or submit under the Exchange Act is (i) recorded, processed, 
summarized and reported, within the time periods specified in the SEC’s rules and forms and (ii) accumulated and 
communicated to our management, including our principal executive and principal financial officer, as appropriate to 
allow timely decisions regarding required disclosures. 

Management’s Annual Report on Internal Control Over Financial Reporting. The management of the Company 

is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s 
internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. We conducted an evaluation of the effectiveness of the internal controls over financial 
reporting based on the framework in Internal Control - Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission. This evaluation included a review of the documentation of controls, 
evaluation of the design effectiveness of controls, testing the operating effectiveness of the controls and a conclusion 
on this evaluation. Because of its inherent limitations, internal control over financial reporting may not prevent or 
detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance 
with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to 
future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the 
degree of compliance with the policies or procedures may deteriorate. 

Management assesses the effectiveness of the Company’s internal control over financial reporting at the end of 

each quarter. We concluded that our internal control over financial reporting was not effective as of September 30, 
2018 and June 30, 2018, because we identified a material weakness during the second quarter of 2018. We had an 
inadequate review of the calculation of our income tax provision and related disclosures, specifically our evaluation of 
the need for and the adequacy of a valuation allowance against our net deferred tax assets (which consist largely of net 
operating loss carryforwards and federal and state tax credits). We have implemented some changes to our internal 
controls over financial reporting, including the scheduling of more formal communications between ourselves and our 
tax consultant regarding our income tax provision and related disclosures. As a result, we have concluded that this ma-
terial weakness over internal controls has been remediated as of December 31, 2018. Based on management’s as-

29 

 
 
 
 
ImmuCell Corporation 

sessment, we believe that our internal control over financial reporting was effective as of December 31, 2018. 

This Annual Report does not include an attestation report of the Company’s independent registered public 
accounting firm regarding internal control over financial reporting. Management’s internal control report was not 
subject to attestation by the Company’s independent registered public accounting firm pursuant to rules of the 
Securities and Exchange Commission that permit the Company to provide only management’s report. 

Changes in Internal Controls over Financial Reporting. The individual who serves as our principal executive 
and principal financial officer periodically evaluates any change in internal control over financial reporting that has 
occurred during the prior fiscal quarter. We have concluded that there was no change in our internal control over 
financial reporting that occurred during the quarter ended December 31, 2018 that has materially affected, or is 
reasonably likely to materially affect, our internal control over financial reporting.

PART III 

ITEM 10 — DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE 

Executive Officers of the Company 

Our executive officers as of March 21, 2019 were as follows: 

MICHAEL F. BRIGHAM (Age: 58, Officer since 1991, Director since 1999) was appointed to serve as 
President and Chief Executive Officer in February 2000, while maintaining the titles of Treasurer and Secretary, and 
was appointed to serve as a Director of the Company in March 1999. He previously had been elected Vice President of 
the Company in December 1998 and had served as Chief Financial Officer since October 1991. He has served as 
Secretary since December 1995 and as Treasurer since October 1991. Prior to that, he served as Director of Finance 
and Administration since originally joining the Company in September 1989. Mr. Brigham has been a member of the

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Stockholders and the Board of Directors of ImmuCell Corporation 

Opinion on the Financial Statements 

We have audited the accompanying balance sheets of ImmuCell Corporation (the Company) as of December 31, 
2018 and 2017, the related statements of operations, comprehensive income, stockholders’ equity and cash flows for 
the years then ended, and the related notes to the financial statements (collectively, the financial statements). In our 
opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of 
December 31, 2018 and 2017, and the results of its operations and its cash flows for the years then ended, in 
conformity with accounting principles generally accepted in the United States of America. 

Basis for Opinion 

These financial statements are the responsibility of the Company’s management. Our responsibility is to express 
an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with 
the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with 
respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the 
Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan 

and perform the audit to obtain reasonable assurance about whether the financial statements are free of material 
misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an 
audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of 
internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the 
Company’s internal control over financial reporting. Accordingly, we express no such opinion. 

Our audits included performing procedures to assess the risks of material misstatement of the financial 
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures 
included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our 
audits also included evaluating the accounting principles used and significant estimates made by management, as well 
as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis 
for our opinion. 

/s/ RSM US LLP 

We have served as the Company’s auditor since 2016.

Notes to Audited Financial Statements   

1. BUSINESS OPERATIONS 

ImmuCell Corporation (the “Company”, “we”, “us”, “our”) was originally incorporated in Maine in 1982 and 
reincorporated in Delaware in 1987, in conjunction with its initial public offering of common stock. We are an animal 
health company whose purpose is to create scientifically-proven and practical products that improve the health and 
productivity of dairy and beef cattle. We market products that provide Immediate Immunity™ to newborn dairy and 
beef cattle. We are developing product line extensions and are in the late stages of developing a treatment for mastitis, 
the most significant cause of economic loss to the dairy industry. These products help reduce the need to use 
traditional antibiotics in food producing animals. The Company is subject to certain risks associated with its stage of 
development including dependence on key individuals and third-party providers of critical goods and services, 
competition from other larger companies, the successful sale of existing products and the development and acquisition 
of additional commercially viable products with appropriate regulatory approvals, where applicable. Based on our best 
estimates and projections, we believe that we have sufficient capital resources to continue operations for at least 
twelve months from the date of this filing.   

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

(a) Basis of Presentation 

We have prepared the accompanying audited financial statements reflecting all adjustments that are, in our 
opinion, necessary in order to ensure that the financial statements are not misleading. We follow accounting standards 
set by the Financial Accounting Standards Board (FASB). The FASB sets generally accepted accounting principles 
(GAAP) that we follow to ensure we consistently report our financial condition, results of operations, earnings per 
share and cash flows. References to GAAP in these footnotes are to the FASB Accounting Standards Codification™ 
(Codification). Accordingly, we believe that the disclosures are adequate to ensure that the information presented is 
not misleading.   

(b) Cash and Cash Equivalents   

We consider all highly liquid investment instruments that mature within three months of their purchase dates to 

be cash equivalents. Cash equivalents are principally invested in securities backed by the U.S. government. Certain 
cash balances in excess of Federal Deposit Insurance Corporation (FDIC) limits of $250,000 per financial institution 
per depositor are maintained in money market accounts at financial institutions that are secured, in part, by the 
Securities Investor Protection Corporation. Amounts in excess of these FDIC limits per bank that are not invested in 
securities backed by the U.S. government aggregated $2,268,737 and $3,546,529 as of December 31, 2018 and 2017, 
respectively. We account for investments in marketable securities in accordance with Codification Topic 320, 
Investments — Debt and Equity Securities. See Note 3. 

(c) Accounts Receivable 

Accounts receivable are carried at the original invoice amount less an estimate made for doubtful collection. 
Management determines the allowance for doubtful accounts on a monthly basis by identifying troubled accounts 
and by using historical experience applied to an aging of accounts. Accounts receivable are considered to be past due 
if a portion of the receivable balance is outstanding for more than 30 days. Past due accounts receivable are subject to 
an interest charge. Accounts receivable are written off when deemed uncollectible. The amount of accounts 
receivable written off during all periods reported was immaterial. Recoveries of accounts receivable previously 
written off are recorded as income when received. As of December 31, 2018 and 2017, we determined that no 
allowance for bad debt was necessary. See Note 4. 

(d) Inventory 

Inventory includes raw materials, work-in-process and finished goods and is recorded at the lower of cost, on the 

first-in, first-out method, or net realizable value (determined as the estimated selling price in the normal course of

F-7 

 
ImmuCell Corporation 
Notes to Audited Financial Statements (continued) 

business, less reasonably predictable costs of completion, disposal and transportation). Work-in-process and finished 
goods inventories include materials, labor and manufacturing overhead. At each monthly balance sheet date, we 
evaluate our ending inventories for excess quantities and obsolescence. Inventories that we consider excess or obsolete 
are reserved. Once inventory is written down and a new cost basis is established, it is not written back up if demand 
increases. We believe that supplies and raw materials for the production of our products are available from more than 
one vendor or farm. Our policy is to maintain more than one source of supply for the components used in our products 
when practicable. See Note 5. 

  (e) Property, Plant and Equipment 

We depreciate property, plant and equipment on the straight-line method by charges to operations and costs of 
goods sold in amounts estimated to expense the cost of the assets from the date they are first put into service to the end 
of the estimated useful lives of the assets. The facility we have constructed to produce the active pharmaceutical 
ingredient, Nisin, is being depreciated over 39 years from when a certificate of occupancy was issued during the fourth 
quarter of 2017. We began depreciating the equipment for our Nisin production facility when it was placed in service 
during the third quarter of 2018. Approximately 89% of these assets are being depreciated over ten years. Significant 
repairs to fixed assets that benefit more than a current period are capitalized and depreciated over their useful lives. 
Insignificant repairs are expensed when incurred. See Note 7. 

(f) Intangible Assets and Goodwill 

We amortize intangible assets on the straight-line method by charges to costs of goods sold in amounts estimated 
to expense the cost of the assets from the date they are first put into service to the end of the estimated useful lives of 
the assets. We have recorded intangible assets related to customer relationships, non-compete agreements, and 
developed technology, each with defined useful lives. We have classified as goodwill the amounts paid in excess of 
fair value of the net assets (including tax attributes) acquired in purchase transactions. 

We assess the impairment of intangible assets and goodwill that have indefinite lives at the reporting unit level 
on an annual basis (as of December 31st) and whenever events or changes in circumstances indicate that the carrying 
value of the asset may not be recoverable. We would record an impairment charge if such an assessment were to 
indicate that the fair value of such assets was less than the carrying value. Judgment is required in determining whether 
an event has occurred that may impair the value of goodwill or identifiable intangible assets. Factors that could 
indicate that an impairment may exist include significant under-performance relative to plan or long-term projections, 
significant changes in business strategy and significant negative industry or economic trends. Although we believe 
intangible assets and goodwill are properly stated in the accompanying financial statements, changes in strategy or 
market conditions could significantly impact these judgments and require an adjustment to the recorded balance. No 
goodwill impairments were recorded during the years ended December 31, 2018 or 2017. See Notes 2(h), 8 and 9 for 
additional disclosures. 

(g) Fair Value Measurements 

In determining fair value measurements, we follow the provisions of Codification Topic 820, Fair Value 

Measurements and Disclosures. Codification Topic 820 defines fair value, establishes a framework for measuring fair 
value under GAAP and enhances disclosures about fair value measurements. The topic provides a consistent definition 
of fair value which focuses on an exit price, which is the price that would be received to sell an asset or paid to transfer 
a liability in an orderly transaction between market participants at the measurement date. The topic also prioritizes, 
within the measurement of fair value, the use of market-based information over entity-specific information and 
establishes a three-level hierarchy for fair value measurements based on the nature of inputs used in the valuation of an 
asset or liability as of the measurement date. As of December 31, 2018 and 2017, the carrying amounts of cash and 
cash equivalents, accounts receivable, inventory, other assets, accounts payable, deferred revenue and accrued 
liabilities approximate fair value because of their short-term nature. The amount outstanding under our bank debt 
facilities is measured at carrying value in our accompanying balance sheets. Our bank debt facilities are valued using   
Level 2 inputs. The estimated fair value of our bank debt facilities approximates their carrying value based on similar 
instruments with similar maturities. The three-level hierarchy is as follows: 

F-8 

 
 
ImmuCell Corporation 
Notes to Audited Financial Statements (continued) 

Level 1 — Pricing inputs are quoted prices available in active markets for identical assets or liabilities as  of the 

measurement date. 

Level 2 — Pricing inputs are quoted prices for similar assets or liabilities, or inputs that are observable, either 
directly or indirectly, for substantially the full term through corroboration with observable market 
data. 

Level 3 — Pricing inputs are unobservable for the assets or liabilities, that is, inputs that reflect the reporting 

entity’s own assumptions about the assumptions market participants would use in pricing the asset or 
liability. 

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In 

such cases, an asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is 
significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value 
measurement in its entirety requires judgment, and considers factors specific to the investment. From time to time, we 
also hold money market mutual funds in a brokerage account, which are classified as cash equivalents and measured at 
fair value. The fair value of these investments is based on their closing published net asset value. 

We assess the levels of the investments at each measurement date, and transfers between levels are recognized 
on the actual date of the event or change in circumstances that caused the transfer in accordance with our accounting 
policy regarding the recognition of transfers between levels of the fair value hierarchy. During the years ended 
December 31, 2018 and 2017, there were no transfers between levels. As of December 31, 2018 and 2017, our Level 1 
assets measured at fair value by quoted prices in active markets consisted of bank savings accounts and money market 
funds. As of December 31, 2018 and 2017, our interest rate swaps were classified as Level 2 and were measured by 
observable market data in combination with expected cash flows for each instrument. There were no assets or 
liabilities measured at fair value on a nonrecurring basis as of December 31, 2018 or 2017.

We periodically evaluate our long-lived assets, consisting principally of fixed assets and amortizable intangible 
assets, for potential impairment. In accordance with the applicable accounting guidance for the treatment of long-lived 
assets, we review the carrying value of our long-lived assets or asset group that is held and used, including intangible 
assets subject to amortization, for impairment whenever events and circumstances indicate that the carrying value of 
the assets may not be recoverable. Under the held for use approach, the asset or asset group to be tested for impairment 
should represent the lowest level for which identifiable cash flows are largely independent of the cash flows of other 
groups of assets and liabilities. We evaluate our long-lived assets whenever events or circumstances suggest that the

carrying amount of an asset or group of assets may not be recoverable. No impairment was recognized during the years 
ended December 31, 2018 and 2017. 

(i) Concentration of Risk 

Concentration of credit risk with respect to accounts receivable is principally limited to certain customers to 

whom we make substantial sales. To reduce risk, we routinely assess the financial strength of our customers and, as a 
consequence, believe that our accounts receivable credit risk exposure is limited. We maintain an allowance for 
potential credit losses when deemed necessary, but historically we have not experienced significant credit losses 
related to an individual customer or groups of customers in any particular industry or geographic area. Sales to 
significant customers that amounted to 10% or more of total product sales are detailed in the following table:

All derivatives are recognized on the balance sheet at their fair value. We entered into interest rate swap 
agreements in 2010 and 2015. On the dates the agreements were entered into, we designated the derivatives as hedges 
of the variability of cash flows to be paid related to our long-term debt. The agreements have been determined to be 
highly effective in hedging the variability of identified cash flows, so changes in the fair market value of the interest 
rate swap agreements are recorded as comprehensive income (loss), until earnings are affected by the variability of 
cash flows (e.g., when periodic settlements on a variable-rate asset or liability are recorded in earnings). We formally 
documented the relationship between the interest rate swap agreements and the related hedged items. We also formally 
assess, both at the interest rate swap agreements’ inception and on an ongoing basis, whether the agreements are 
highly effective in offsetting changes in cash flow of hedged items. See Note 11. 

(k) Revenue Recognition   

We sell products that provide Immediate Immunity™ to newborn dairy and beef cattle. For periods ended 

on and before December 31, 2017, we recognized revenue in accordance with Accounting Standards Codification 
(ASC) 605 when four criteria were met. These included i) persuasive evidence that an arrangement existed, ii) delivery 
had occurred, iii) our price was fixed and determinable and iv) collectability was reasonably assured. For periods 
beginning on or after January 1, 2018, we recognize revenue in accordance with ASC 606, Revenue from Contracts 
with Customers. ASC 606 is a single comprehensive model for companies to use in accounting for revenue arising from 
contracts with customers. The core principle is that we recognize the amount of revenue to which we expect to be entitled 
for the transfer of promised goods or services to customers when a customer obtains control of promised goods or services 
in an amount that reflects the consideration we expect to receive in exchange for those goods or services. In addition, the 
standard requires disclosure of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts 
with customers. ASC 606 replaces most existing revenue recognition guidance in accordance with GAAP. We evaluated 
the new standard against our existing accounting policies and practices, including reviewing distributor agreements, 

F-10 

 
 
 
 
 
 
 
ImmuCell Corporation 
Notes to Audited Financial Statements (continued) 

purchase orders, invoices and shipping forms, and conducting questionnaires with our sales team. We adopted the 
standard using the modified retrospective transition method, and the adoption did not have a material impact on our 
financial statements as of the date of adoption (January 1, 2018). Comparative prior periods have not been adjusted and 
continue to be reported under ASC 605. We conduct our business with customers through valid purchase orders or sales orders 
which are considered contracts and are not interdependent on one another. A performance obligation is a promise in a contract 
to transfer a distinct product to the customer. The transaction price is the amount of consideration we expect to receive under 
the arrangement. Revenue is measured based on consideration specified in a contract with a customer. The transaction price of 
a contract is allocated to each distinct performance obligation and recognized when or as the customer receives the benefit of 
the performance obligation. Product transaction prices on a purchase or sale order are discrete and stand-alone. We recognize 
revenue when we satisfy a performance obligation in a contract by transferring control over a product to a customer when 
product delivery occurs. Consideration is typically paid approximately 30 days from the time control is transferred. Shipping 
and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for 
as a fulfillment cost in costs of goods sold. We have enhanced disclosures related to disaggregation of revenue sources and 
accounting policies prospectively as a result of adopting these standards. We do not bill for or collect sales tax because 
our sales are generally made to distributors and thus our sales to them are not subject to sales tax. We generally have 
experienced an immaterial amount of product returns. See Note 13. 

  (l) Expense Recognition 

In 2018, we adopted ASC 340-40, Accounting for Other Assets and Deferred Costs, which requires sales 

commissions and other third party acquisition costs resulting directly from securing contracts with customers to be 
recognized as an asset when incurred and to be expensed over the associated contract term or estimated customer life 
depending on the nature of the underlying contract. We do not incur costs in connection with product sales to customers that 
are eligible for capitalization. Advertising costs are expensed when incurred, which is generally during the month in 
which the advertisement is published. Advertising expenses amounted to $28,415 and $55,263 during the years ended 
December 31, 2018 and 2017, respectively. All product development expenses are expensed as incurred, as are all 
related patent costs. We capitalize costs to produce inventory during the production cycle, and these costs are charged 
to costs of goods sold when the inventory is sold to a customer. Adoption of the amended provisions of ASC 340-40 
did not have a material impact on our financial statements. 

(m) Income Taxes   

  We account for income taxes in accordance with Codification Topic 740, Income Taxes, which requires that 
we recognize a current tax liability or asset for current taxes payable or refundable and a deferred tax liability or asset 
for the estimated future tax effects of temporary differences and carryforwards to the extent they are realizable. During 
the second quarter of 2018, we assessed our historical and near-term future profitability and decided to record 
$563,252 in non-cash income tax expense to create a full valuation allowance against our net deferred tax assets 
(which consist largely of net operating loss carryforwards and federal and state tax credits). At that time, we had 
incurred a net loss for six consecutive quarters, had not been profitable on a year-to-date basis since the nine-month 
period ended September 30, 2017 and projected additional net losses for some period going forward before returning 
to profitability. We consider future taxable income and feasible tax planning strategies in assessing the need for a 
valuation allowance at each quarter end. If we determine that we would be able to realize our deferred tax assets in the 
future in excess of the net recorded amount over a reasonably short period of time, a reduction of the valuation 
allowance would increase income in the period such determination was made. Likewise, if we determine that we 
would not be able to realize all or part of our net deferred tax asset in the future, an increase to the valuation allowance 
would be charged to income in the period such determination was made. 

Codification Topic 740-10 clarifies the accounting for income taxes by prescribing a minimum recognition 

threshold that a tax position must meet before being recognized in the financial statements. In the ordinary course of 
business, there are transactions and calculations where the ultimate tax outcome is uncertain. In addition, we are 
subject to periodic audits and examinations by the Internal Revenue Service and other taxing authorities. With few 
exceptions, we are no longer subject to income tax examinations by tax authorities for years before 2015. We have 
evaluated the positions taken on our filed tax returns. We have concluded that no uncertain tax positions exist as of 
December 31, 2018 or 2017. Although we believe that our estimates are reasonable, actual results could differ from 

F-11 

 
ImmuCell Corporation 
Notes to Audited Financial Statements (continued) 

these estimates. See Note 16. 

(n) Stock-Based Compensation 

We account for stock-based compensation in accordance with Codification Topic 718, Compensation-Stock 

Compensation, which generally requires us to recognize non-cash compensation expense for stock-based payments 
using the fair-value-based method. The fair value of each stock option grant has been estimated on the date of grant 
using the Black-Scholes option pricing model. Accordingly, we recorded compensation expense pertaining to 
stock-based compensation of $344,016 and $199,783 during the years ended December 31, 2018 and 2017, 
respectively. 

(o) Net Loss Per Common Share 

Net loss per common share has been computed in accordance with Codification Topic 260-10, Earnings Per 

Share. The net loss per share has been computed by dividing the net loss by the weighted average number of common 
shares outstanding during the period. All stock options have been excluded from the denominator in the calculation of 
dilutive earnings per share when we are in a loss position, as the inclusion would be anti-dilutive. The weighted 
average number of shares outstanding was 5,486,154 and 4,949,213 during the years ended December 31, 2018 and 
2017, respectively. Outstanding stock options that were not included in this calculation because the effect would be 
anti-dilutive amounted to 394,000 and 360,000 as of December 31, 2018 and 2017, respectively. 

  (p) Use of Estimates 

The preparation of financial statements in conformity with GAAP requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities 
at the date of the financial statements and the reported amounts of revenues and expenses during the period. Although 
we regularly assess these estimates, actual amounts could differ from those estimates. Changes in estimates are 
recorded during the period in which they become known. Significant estimates include our inventory valuation, 
valuation of goodwill and long-lived assets, valuation of deferred tax assets, accrued expenses, costs of goods sold, 
and useful lives of intangible assets. 

  (q) New Accounting Pronouncements 

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The guidance in this ASU supersedes the 

leasing guidance in Topic 840, Leases. Under the new guidance, lessees are required to recognize lease assets and 
lease liabilities on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either 
finance or operating, with classification affecting the pattern of expense recognition in the income statement. This 
ASU and its amendments are effective for fiscal years beginning after December 15, 2018, including interim periods 
within those fiscal years. Early adoption was permitted. We elected to adopt this ASU effective January 1, 2019. In 
July 2018, the FASB issued ASU 2018-10, Codification improvements to Topic 842, Leases. The amendments in ASU 
2018-10 provide more clarification in regards to the application and requirements of ASU 2016-02. In July 2018, the 
FASB issued ASU 2018-11, Topic 842, Leases - Targeted improvements. The amendments in ASU 2018-11 provide 
for the option to adopt the standard prospectively and recognize a cumulative-effect adjustment to the opening balance 
of retained earnings as well as offer a new practical expedient that will allow the Company to elect, by class of un-
derlying asset, to not separate non-lease and lease components in certain circumstances and instead to account for 
those components as a single item. Based on our current lease agreements and a review of all of our material vendor 
relationships for potential embedded lease obligations, we have concluded that we are not subject to material lease obli-
gations, and the adoption of ASU 2016-02 did not have a material impact on our financial statements as of January 1, 
2019. 

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718) Scope of 
Modification Accounting to provide clarity and reduce both diversity in practice and cost complexity when applying 
the guidance in Topic 718 to a change to the terms and conditions of a stock-based payment award. ASU 2017-09 also 
provides guidance about the types of changes to the terms or conditions of a share-based payment award that require 
an entity to apply modification accounting in accordance with Topic 718. The standard is effective for interim and 
annual reporting periods beginning after December 15, 2017, with early adoption permitted. We adopted this guidance 

F-12 

 
ImmuCell Corporation 
Notes to Audited Financial Statements (continued) 

during the three-month period ended March 31, 2018. The adoption of this guidance did not have a material impact on 
our financial statements.   

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements 

to Accounting for Hedging Activities. The new guidance is intended to more closely align hedge accounting with 
entities’ hedging strategies, simplify the application of hedge accounting and increase the transparency of hedging 
programs. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, including interim periods 
within those fiscal years, with early adoption permitted. For cash flow and net investment hedges existing at the date of 
adoption, ASU 2017-12 must be applied through a cumulative-effect adjustment. The amended presentation and 
disclosure guidance is required only prospectively. The adoption of ASU 2017-12 did not to have a material impact on 
our financial statements as of January 1, 2019. 

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure 

Framework-Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure 
requirements of fair value measurements. Topic 820 is effective for fiscal years beginning after December 15, 2019, 
and early adoption is permitted. The adoption of this guidance is not expected to have a material impact on our 
financial statements. 

3. CASH AND CASH EQUIVALENTS   

Cash and cash equivalents amounted to $2,521,050 and $3,798,811 as of December 31, 2018 and 2017, 

respectively. Short-term investments were liquidated during 2017 to partially finance the investment in our Nisin 
production facility. The cost of securities sold is based on the specific identification method. Realized gains and losses 
and declines in value, judged to be other than temporary, are included in investment income. We are required by bank 
debt covenant to maintain at least $2,000,000 of otherwise unrestricted cash, cash equivalents and short-term 
investments. 

4. TRADE ACCOUNTS RECEIVABLE, net 

Trade accounts receivable amounted to $932,298 and $1,344,022 as of December 31, 2018 and 2017,

of manufacturing equipment. As of December 31, 2017, construction in progress consisted principally of payments for 
equipment to be used in our Nisin production facility. Approximately $22,681 and $435,448 of property, plant and 
equipment was disposed of during the years ended December 31, 2018 and 2017, respectively. Depreciation expense 
was approximately $1,501,607 and $885,331 during the years ended December 31, 2018 and 2017, respectively. 

8. BUSINESS ACQUISITION 

On January 4, 2016, we acquired certain business assets and processes from DAY 1™ Technology, LLC of 

Minnesota. The acquired rights and know-how are primarily related to formulating our bovine antibodies into a gel 
solution (or paste) for an oral delivery option to newborn calves via a syringe (or tube). This product format offers 
customers an alternative delivery option to the bolus (the standard delivery format of the bivalent First Defense® 
product since first approval by the U.S. Department of Agriculture (USDA) and product launch in 1991). This gel 
formulation had been sold as a feed product without disease claims since 2012. During the fourth quarter of 2018, we 
achieved USDA approval of an improved bivalent gel formulation and began marketing this product as Dual-Force™ 
First Defense®. We achieved Canadian approval of this product during the first quarter of 2019. We were also 
interested in a gel formulation in anticipation of the launch of Tri-Shield First Defense® (which was approved by the 
USDA during the fourth quarter of 2017) because the additional rotavirus antibodies in this new product would not fit 
in a bolus full of E. coli and coronavirus antibodies. This purchase also included certain other related private-label 
products. The total purchase price was approximately $532,000. Approximately $368,000 of this amount was paid as 
of the closing date. A technology transfer payment of $97,000 was made during the third quarter of 2016. There were 
also royalty payments owed based on a percentage of sales made through December 31, 2018, which were due 
semi-annually in January and July. As of January 4, 2016, we estimated the aggregate royalties to be paid would be 
approximately $67,000, which was recorded in accounts payable and accrued expenses. Royalty expense of $17,268, 
$10,615 and $8,200 was incurred for sales recorded during the years ended December 31, 2018, 2017 and 2016, 
respectively. As of December 31, 2018, the amount due was approximately $8,914, which was recorded in accounts 
payable. The estimated fair values of the assets purchased in this transaction included inventory of approximately 
$113,000, machinery and equipment of approximately $132,000, a developed technology intangible of approximately 
$191,000 (which includes an immaterial amount of value associated with customer relationships and a non-compete 
agreement, and was valued using the relief from royalty method) and goodwill of approximately $96,000. The 
goodwill arising from the acquisition consists largely of the estimated value of anticipated growth opportunities 
arising from synergies and efficiencies. The measurement period for the transaction was closed as of June 30, 2016, 
and we continue to assess any impairment of these assets acquired in accordance with our policies. The impact of the 
acquisition on our pro forma prior year operations is not material. As of December 31, 2016, we vacated the rented 
facility in Minnesota that had been used to produce the gel solution format of our product and certain other related 

F-14

private-label products. This resulted in the termination of employment of four employees, as these production 
functions were consolidated into our Portland facility, which enables us to better utilize existing infrastructure and 
larger scale equipment to improve operating efficiencies. 

9. INTANGIBLE ASSETS 

The intangible assets described in Note 8 are being amortized to costs of goods sold over their useful lives, 
which are estimated to be 10 years. Intangible amortization expense was $19,104 during both of the years ended 
December 31, 2018 and 2017. The net value of these intangibles was $133,728 as of December 31, 2018. A summary 
of intangible amortization expense estimated for the periods subsequent to December 31, 2018 is as follows:

Notes to Audited Financial Statements (continued) 

The first note (Loan #1) is not to exceed 80% of the appraised value of our corporate headquarters and 
production and research facility at 56 Evergreen Drive in Portland. Proceeds of $1,000,000 were received during the 
third quarter of 2010 with monthly principal and interest payments due for ten years, calculated based on a fifteen-year 
amortization schedule. A balloon principal payment of $451,885 will be due during the third quarter of 2020. As of 
December 31, 2018, $562,604 was outstanding under Loan #1.   

Proceeds from a $2,500,000 second mortgage on this corporate headquarters (Loan #2) were received during the 
third quarter of 2015 with monthly principal and interest payments due for ten years, calculated based on a twenty-year 
amortization schedule. A balloon principal payment of approximately $1,550,000 will be due during the third quarter 
of 2025. As of December 31, 2018, $2,233,768 was outstanding under Loan #2.   

During the first quarter of 2016, we entered into two additional credit facilities (Loans #3 and #4) aggregating up 
to approximately $4,500,000. As a result of loan amendments entered into the during the first quarter of 2017, these 
two credit facilities were increased to up to $6,500,000, subject to certain restrictions set forth in the agreements. Loan 
#3 is comprised of a construction loan of up to $3,940,000 and not to exceed 80% of the cost of the equipment installed 
in our commercial-scale Nisin production facility at 33 Caddie Lane in Portland. As amended, interest only was 
payable at a variable rate equal to the one-month LIBOR (adjusted at each monthly payment date) plus a margin of 
2.25% through September 2018, at which time the loan converted to a seven-year term loan facility at the same 
variable interest rate (which was equal to 4.60% as of December 31, 2018) with monthly principal and interest 
payments due based on a seven-year amortization schedule. As of December 31, 2018, $3,799,286 was outstanding 
under Loan #3. Loan #4 is comprised of a construction loan of up to $2,560,000 and not to exceed 80% (75% prior to 
the 2017 amendments) of the appraised value of our commercial-scale Nisin production facility. As amended, interest 
only was payable at a variable rate equal to the one-month LIBOR (adjusted at each monthly payment date) plus a 
margin of 2.25% through March 2018, at which time the loan converted to a term loan facility at the same variable 
interest rate (which was equal to 4.60% as of December 31, 2018) with monthly principal and interest payments due 
for ten years, calculated based on a twenty-year amortization schedule. A balloon principal payment of approximately 
$1,408,000 will be due during the first quarter of 2027. As of December 31, 2018, $2,464,000 was outstanding under 
Loan #4.   

The fifth note (Loan #5) is a mortgage that is secured by the 4,114 square foot warehouse and storage facility we 
acquired adjacent to our Nisin production facility. Proceeds of $340,000 were received during the first quarter of 2017. 
This note bears interest at a variable rate equal to the one-month LIBOR (adjusted at each monthly payment date) plus 
a margin of 2.25% (which was equal to 4.71% as of December 31, 2018) with monthly principal and interest payments 
due for ten years, calculated based on a twenty-year amortization schedule. A balloon principal payment of 
approximately $208,000 will be due during the first quarter of 2027. As of December 31, 2018, $320,767 was 
outstanding under Loan #5. 

We hedged our interest rate exposures on Loan #1 and Loan #2 with interest rate swap agreements that 
effectively converted floating interest rates based on the one-month LIBOR plus a margin of 3.25% and 2.25% to the 
fixed rates of 6.04% and 4.38%, respectively. As of December 31, 2018, the variable rates on these two mortgage 
notes were 5.68% and 4.73%, respectively. All derivatives are recognized on the balance sheet at their fair value. At 
the time of the closings and thereafter, the agreements were determined to be highly effective in hedging the variability 
of the identified cash flows and have been designated as cash flow hedges of the variability in the hedged interest 
payments. Changes in the fair value of the interest rate swap agreements are recorded in other comprehensive income, 
net of taxes. The original notional amounts of the interest rate swap agreements of $1,000,000 and $2,500,000 
amortize in accordance with the amortization of the mortgage notes. The notional amount of the interest rate swaps 
was $2,796,372 as of December 31, 2018. The fair values of the interest rate swaps have been determined using 
observable market-based inputs or unobservable inputs that are corroborated by market data. Accordingly, the interest 
rate swaps are classified as level 2 within the fair value hierarchy provided in Codification Topic 820, Fair Value 
Measurements and Disclosures.

been renewed approximately annually since then, is available as needed and has been extended through May 31, 2020. 
As of December 31, 2018, $500,000 was outstanding under this line of credit. There was no outstanding balance under 
this line of credit as of December 31, 2017. Interest on borrowings against the line of credit is variable at the higher of

and Exchange Commission (SEC) for the potential issuance of up to $10,000,000 in equity securities (subject to 
certain limitations). This registration statement became effective on November 10, 2015. Under this form of 
registration statement, we were limited within a twelve-month period to raising gross proceeds of no more than 
one-third of the market capitalization of our common stock (as determined by the high price of our common stock 
within the preceding 60 days leading up to a sale of securities) held by non-affiliates (non-insiders) of the Company. 
Having raised $10,000,000 in gross proceeds under the February 2016, July 2017 and December 2017 equity 
transactions described below, no additional equity securities can be issued under this registration statement. 

On February 3, 2016, we sold 1,123,810 shares of common stock at a price to the public of $5.25 per share in an 
underwritten public offering pursuant to our effective shelf registration statement on Form S-3, raising gross proceeds 
of approximately $5,900,000 and resulting in net proceeds to the Company of approximately $5,313,000 (after 
deducting underwriting discounts and offering expenses incurred in connection with the equity financing). 

On October 21, 2016, we closed on a private placement of 659,880 shares of common stock to nineteen 

institutional and accredited investors at $5.25 per share, raising gross proceeds of approximately $3,464,000 and 
resulting in net proceeds to the Company of approximately $3,161,000 (after deducting placement agent fees and other 
expenses incurred in connection with the equity financing). 

On July 27, 2017, we issued 200,000 shares of our common stock at a price of $5.25 per share to two related 

investors pursuant to our effective shelf registration statement on Form S-3, raising gross proceeds of $1,050,000 and 
resulting in net proceeds of approximately $1,034,000 (after deducting expenses incurred in connection with the 
equity financing). 

On December 21, 2017, we sold 417,807 shares of common stock at a price to the public of $7.30 per share in an 
underwritten public offering pursuant to our effective shelf registration statement on Form S-3, raising gross proceeds 
of approximately $3,050,000 and resulting in net proceeds to the Company of approximately $2,734,000 (after 
deducting underwriting discounts and offering expenses incurred in connection with the equity financing).   

On November 20, 2018, we filed a registration statement on Form S-3 (File No. 333-228479) with the Securities 
and Exchange Commission (SEC) for the potential issuance of up to $20,000,000 in equity securities (subject to certain 
limitations). This registration statement became effective on November 29, 2018. Under this form of registration 
statement, we are limited within a twelve-month period to raising gross proceeds of no more than one-third of the market 
capitalization of our common stock (as determined by the high price of our common stock within the preceding 60 days 
leading up to a sale of securities) held by non-affiliates (non-insiders) of the Company. 

At the June 15, 2016 Annual Meeting of Stockholders, we reported that our stockholders voted to approve an 

amendment to the Company’s Certificate of Incorporation to increase the number of shares of common stock 
authorized for issuance from 8,000,000 to 10,000,000. After careful consideration, we determined that the method of 
voting instructions described in our Proxy Statement was not consistent with the way the votes were actually recorded 
in accordance with stock exchange rules. Therefore, during the second quarter of 2017, we elected to treat the 
amendment as ineffective, and there was no increase in our authorized common stock. At the June 14, 2018 Annual 
Meeting of Stockholders, our stockholders voted to approve an amendment to the Company’s Certificate of 
Incorporation to increase the number of shares of common stock authorized for issuance from 8,000,000 to 11,000,000.   

In June 2000, our stockholders approved the 2000 Stock Option and Incentive Plan (the “2000 Plan”) pursuant 
to the provisions of the Internal Revenue Code of 1986, under which employees and certain service providers may be 
granted options to purchase shares of the Company’s common stock at i) no less than fair market value on the date of 
grant in the case of incentive stock options and ii) no less than 85% of fair market value on the date of grant in the case 
of non-qualified stock options. Vesting requirements are determined by the Compensation and Stock Option 
Committee of the Board of Directors on a case by case basis. Originally, 250,000 shares of common stock were 
reserved for issuance under the 2000 Plan. The stockholders of the Company approved an increase in this number to 
500,000 shares in June 2001. All options granted under the 2000 Plan expire no later than ten years from the date of 
grant. The 2000 Plan expired in February 2010, after which date no further options could be granted under the 2000 

F-18

Plan. However, outstanding options under the 2000 Plan may be exercised in accordance with their terms. 

In June 2010, our stockholders approved the 2010 Stock Option and Incentive Plan (the “2010 Plan”) pursuant 
to the provisions of the Internal Revenue Code of 1986, under which employees and certain service providers may be 
granted options to purchase shares of the Company’s common stock at no less than fair market value on the date of 
grant. At that time, 300,000 shares of common stock were reserved for issuance under the 2010 Plan and subsequently 
no additional shares have been reserved for the 2010 Plan. Vesting requirements are determined by the Compensation 
and Stock Option Committee of the Board of Directors on a case by case basis. All options granted under the 2010 
Plan expire no later than ten years from the date of grant. The 2010 Plan expires in June 2020, after which date no 
further options could be granted under the 2010 Plan. However, options outstanding under the 2010 Plan at that time 
could be exercised in accordance with their terms. 

In June 2017, our stockholders approved the 2017 Stock Option and Incentive Plan (the “2017 Plan”) pursuant 
to the provisions of the Internal Revenue Code of 1986, under which employees and certain service providers may be 
granted options to purchase shares of the Company’s common stock at no less than fair market value on the date of 
grant. At that time, 300,000 shares of common stock were reserved for issuance under the 2017 Plan and subsequently 
no additional shares have been reserved for the 2017 Plan. Vesting requirements are determined by the Compensation 
and Stock Option Committee of the Board of Directors on a case by case basis. All options granted under the 2017 
Plan expire no later than ten years from the date of grant. The 2017 Plan expires in March 2027, after which date no 
further options could be granted under the 2017 Plan. However, options outstanding under the 2017 Plan at that time 
could be exercised in accordance with their terms.

During the year ended December 31, 2018, seven employees exercised stock options covering an aggregate of 

107,000 shares, of which 51,500 of these shares were acquired for cash, resulting in total proceeds of $96,240, and 
55,500 of these shares were acquired by the surrender of 14,235 shares of common stock with a fair market value of 
$105,785 at the time of exercise and $14 in cash. During the year ended December 31, 2017, six employees exercised 
stock options covering 11,000 shares for cash, resulting in total proceeds of $49,560. 

The weighted average remaining life of the options outstanding under the 2000 Plan, the 2010 Plan and the 2017 
plan as of December 31, 2018 was approximately 6 years and 7 months. The weighted average remaining life of the 
options exercisable under these plans as of December 31, 2018 was approximately 2 years and 7 months. The exercise 
prices of the options outstanding as of December 31, 2018 ranged from $3.15 to $8.90 per share. The 171,000 stock 
options granted during the year ended December 31, 2018 had exercise prices between $6.81 and $8.43 per share. The 
141,000 stock options granted during the year ended December 31, 2017 had exercise prices between $5.33 and $8.90 
per share. The aggregate intrinsic value of options exercised during 2018 and 2017 approximated $582,590 and 
$43,470, respectively. The weighted-average grant date fair values of options granted during 2018 and 2017 were 
$3.83 and $3.51 per share, respectively. As of December 31, 2018, total unrecognized stock-based compensation 
related to non-vested stock options aggregated $645,261, which will be recognized over a weighted average period of 
1 year and 9 months. The fair value of each stock option grant has been estimated on the date of grant using the 
Black-Scholes option pricing model, for the purpose discussed in Note 2(n), with the following weighted-average 
assumptions for the years ended December 31, 2018 and 2017: 

Risk-free interest rate 
Dividend yield 
Expected volatility 
Expected life 

For the Year Ended 
December 31, 2018 
2.6% 
0% 
56% 
5.4 years 

For the Year Ended 
December 31, 2017 
1.9% 
0% 
61% 
6.5 years 

The risk-free interest rate is based on U.S. Treasury yields for a maturity approximating the expected option 

term, while the other assumptions are derived from averages of our historical data. 

Common Stock Rights Plan 

In September 1995, our Board of Directors adopted a Common Stock Rights Plan (the “Rights Plan”) and 

declared a dividend of one common share purchase right (a “Right”) for each of the then outstanding shares of the 
common stock of the Company. Each Right entitles the registered holder to purchase from the Company one share of 
common stock at an initial purchase price of $70.00 per share, subject to adjustment. The description and terms of the 
Rights are set forth in a Rights Agreement between the Company and American Stock Transfer & Trust Co., as Rights 
Agent. 

The Rights (as amended) become exercisable and transferable apart from the common stock upon the earlier of 
i) 10 days following a public announcement that a person or group (Acquiring Person) has, without the prior consent 

F-20 

 
 
 
 
 
 
 
 
 
 
ImmuCell Corporation 
Notes to Audited Financial Statements (continued) 

of the Continuing Directors (as such term is defined in the Rights Agreement), acquired beneficial ownership of 20% 
or more of the outstanding common stock or ii) 10 days following commencement of a tender offer or exchange offer 
the consummation of which would result in ownership by a person or group of 20% or more of the outstanding 
common stock (the earlier of such dates being called the Distribution Date). 

Upon the Distribution Date, the holder of each Right not owned by the Acquiring Person would be entitled to 

purchase common stock at a discount to the initial purchase price of $70.00 per share, effectively equal to one half of 
the market price of a share of common stock on the date the Acquiring Person becomes an Acquiring Person. If, after 
the Distribution Date, the Company should consolidate or merge with any other entity and the Company were not the 
surviving company, or, if the Company were the surviving company, all or part of the Company’s common stock were 
changed or exchanged into the securities of any other entity, or if more than 50% of the Company’s assets or earning 
power were sold, each Right would entitle its holder to purchase, at the Rights’ then-current purchase price, a number 
of shares of the acquiring company’s common stock having a market value at that time equal to twice the Right’s 
exercise price. 

At any time after a person or group becomes an Acquiring Person and prior to the acquisition by such person or 

group of 50% or more of the outstanding common stock, the Board of Directors of the Company may exchange the 
Rights (other than Rights owned by such person or group which have become void), in whole or in part, at an exchange 
ratio of one share of common stock per Right (subject to adjustment). At any time prior to 14 days following the date 
that any person or group becomes an Acquiring Person (subject to extension by the Board of Directors), the Board of 
Directors of the Company may redeem the then outstanding Rights in whole, but not in part, at a price of $0.005 per 
Right, subject to adjustment.   

At various times over the years, our Board of Directors has voted to authorize amendments of the Rights 

Agreement to extend the Final Expiration Date, which is currently September 19, 2022. Our Board of Directors also has 
voted to authorize amendments to increase the ownership threshold for determining “Acquiring Person” status to 20%. 
During the second quarter of 2015, our Board of Directors also voted to authorize an amendment to remove a provision that 
prevented a new group of directors elected following the emergence of an Acquiring Person (an owner of more than 
20% of our stock) from controlling the Rights Plan by maintaining exclusive authority over the Rights Plan with 
pre-existing directors. We did this because such provisions have come to be viewed with disfavor by Delaware courts. 
Each time that we made such amendments we entered into amendments to the Rights Agreement with the Rights Agent 
reflecting such extensions, threshold increases or provision changes. No other changes have been made to the terms of 
the Rights or the Rights Agreement. 

13. REVENUE   

We primarily offer the First Defense product line to dairy and beef producers to prevent scours in newborn 

calves. Generally, our products are promoted to veterinarians and dairy and beef producers by our sales team and then 
sold through distributors. Our primary market is North America. We do sell into select international regions and may 
expand this international reach in the future. There were no material changes between the allocation and timing of 
revenue recognition during the year ended December 31, 2018 (under ASC 606) and the year ended December 31, 
2017 (under ASC 605). We do not have any contract assets such as contracts for which we have satisfied the per-
formance obligations but do not yet have the right to bill for or contract liabilities such as customer advances. All trade 
receivables on our balance sheet are from contracts with customers. We incur no material costs to obtain contracts. As 
of March 31, 2018, we had a backlog of orders (representing purchase orders received from customers which were not 
fulfilled or paid) worth approximately $1,245,000 for the First Defense® product line. Before June 30, 2018 we 
cleared all of this backlog that was related to orders for our bivalent formats of the First Defense® product line (which 
have been re-branded as Dual-Force™ First Defense). Demand for Tri-Shield First Defense® continues to exceed 
our available inventory, but we are not accepting orders in excess of available inventory, which requires a careful 
allocation of inventory as it becomes available to address the needs of specific customers. As of December 31, 2018, 
we had received orders representing a backlog worth approximately $393,000. We had sufficient inventory on hand to 
satisfy these orders, but this product did not ship to customers until the beginning of 2019 for several reasons including 
the following: i) most of these orders were received during the last two days of the year, ii) product requiring cold 
shipment does not ship over a weekend or holiday and iii) normal shipping services were interrupted due to the holiday 
schedule.

during the third quarter of 2019 and a third payment of $200,000 is due during the fourth quarter of 2019 (both of these 
payments receivable were recorded in prepaid expenses and other current assets as of December 31, 2018).

Our income tax expense (benefit) aggregated $461,620 and ($270,333) (amounting to 25% and (62%) of our 

loss before income taxes, respectively) for the years ended December 31, 2018 and 2017, respectively. As of 
December 31, 2018, we had federal net operating loss carryforwards of $11,839,349 of which $10,127,442 does not 
expire and $1,711,907 expires in 2034 through 2037 (if not utilized before then) and state net operating loss 
carryforwards of $3,485,949 that expire in 2037 through 2038 (if not utilized before then). Additionally, we had 
federal general business tax credit carryforwards of $407,023 that expire in 2027 through 2038 (if not utilized before 
then) and state tax credit carryforwards of $763,350 that expire in 2023 through 2038 (if not utilized before then).   

The provision for income taxes is determined using the asset and liability approach of accounting for income 

taxes. Under this approach, deferred taxes represent the estimated future tax effects of temporary differences between 
book and tax treatment of assets and liabilities and carryforwards to the extent they are realizable. During the second 
quarter of 2018, we assessed our historical and near-term future profitability and recorded $563,252 in non-cash income tax 
expense to create a full valuation allowance against our net deferred tax assets (which consist largely of net operating loss 
carryforwards and federal and state credits). At that time, we had incurred a net loss for six consecutive quarters, had not been

profitable on a year-to-date basis since the nine-month period ended September 30, 2017 and projected additional net losses for 
some period going forward before returning to profitability.   

Net operating loss carryforwards, credits, and other tax attributes are subject to review and possible adjustment 
by the Internal Revenue Service. Section 382 of the Internal Revenue Code contains provisions that could place annual 
limitations on the future utilization of net operating loss carryforwards and credits in the event of a change in 
ownership of the Company, as defined. 

The Company files income tax returns in the U.S. federal jurisdiction and several state jurisdictions. We 
currently have no tax examinations in progress. We also have not paid additional taxes, interest or penalties as a result 
of tax examinations nor do we have any unrecognized tax benefits for any of the periods in the accompanying financial 
statements.

The Tax Cuts and Jobs Act was enacted on December 22, 2017. This legislation made significant changes in the 

U.S. tax laws including a reduction in the corporate tax rates, changes to net operating loss carryforwards and 
carrybacks, and a repeal of the corporate alternative minimum tax. The legislation reduced the U.S. corporate tax rate 
from the prior rate of 34% to 21%. As a result of the enacted law, we were required to revalue deferred tax assets and 
liabilities at the rate enacted in 2017. This revaluation resulted in a benefit of $71,000 to income tax expense in 
continuing operations and a corresponding increase in the deferred tax assets during 2017. On December 22, 2017, the 
SEC issued Staff Accounting Bulletin #118 that provides additional guidance and allows companies to apply a

17. CONTINGENT LIABILITIES AND COMMITMENTS 

Our bylaws, as amended, in effect provide that the Company will indemnify its officers and directors to the 

maximum extent permitted by Delaware law. In addition, we make similar indemnity undertakings to each director 
through a separate indemnification agreement with that director. The maximum payment that we may be required to 
make under such provisions is theoretically unlimited and is impossible to determine. We maintain directors’ and 
officers’ liability insurance, which may provide reimbursement to the Company for payments made to, or on behalf of, 
officers and directors pursuant to the indemnification provisions. Our indemnification obligations were grandfathered 
under the provisions of Codification Topic 460, Guarantees. Accordingly, we have recorded no liability for such 
obligations as of December 31, 2018. Since our incorporation, we have had no occasion to make any indemnification 
payment to any of our officers or directors for any reason. 

The development, manufacturing and marketing of animal health care products entails an inherent risk that 
liability claims will be asserted against us during the normal course of business. We are aware of no such claims 
against us as of the date of this filing. We feel that we have reasonable levels of liability insurance to support our 
operations. 

We enter into agreements with third parties in the ordinary course of business under which we are obligated to 
indemnify such third parties from and against various risks and losses. The precise terms of such indemnities vary with 
the nature of the agreement. In many cases, we limit the maximum amount of our indemnification obligations, but in 
some cases those obligations may be theoretically unlimited. We have not incurred material expenses in discharging 
any of these indemnification obligations, and based on our analysis of the nature of the risks involved, we believe that 
the fair value of the liabilities potentially arising under these agreements is minimal. Accordingly, we have recorded 
no liabilities for such obligations as of December 31, 2018. 

We are committed to purchasing certain key parts (syringes) and services (final formulation, aseptic filling and 

final packaging of Drug Product) pertaining to Re-Tain™, our Nisin-based intramammary treatment of subclinical 
mastitis in lactating dairy cows, exclusively from two contractors. Because we will not achieve regulatory approval for 
the sale of Re-Tain™ in the U.S. by December 17, 2019, the contract counter party for final formulation, aseptic filling 
and final packaging of that product may have the right at that date to terminate the agreement, and we could be liable 
for a $100,000 termination fee. We are negotiating with this party to amend and extend the contract term to allow us to 
achieve regulatory approval and initiate commercial launch with the availability of this party’s services, while we seek 
an alternative contract services provider or raise the funds necessary to build the required infrastructure to perform these 
services for ourselves.   

During the second quarter of 2009, we entered into an exclusive and perpetual (unless terminated for cause) 
license with the Baylor College of Medicine covering the underlying rotavirus vaccine technology used to generate the 

F-24

specific antibodies for our product line extension, Tri-Shield First Defense®. A milestone payment of $150,000 due 
upon regulatory approval of the product was accrued at December 31, 2017 and paid in January 2018. The license is 
also subject to a royalty equal to 4% of the sales of the First Defense® product line realized above the average of the 
sales of our bivalent product line for the years ended December 31, 2016 and 2015, plus a growth assumption of 6%. 
Earned royalties due are subject to annual minimums of $5,000, $10,000, $15,000, $20,000 and $25,000 for the years 
ending December 31, 2017, 2018, 2019, 2020, and 2021 (and thereafter), respectively. Royalties of $5,000 were 
accrued at December 31, 2017 and paid in January 2018. Royalties of $10,396 were accrued at December 31, 2018 and 
paid in January 2019. In addition to the commitments discussed above, we had committed $581,000 to the purchase of 
inventory and $179,000 to other obligations as of December 31, 2018. 

18. SEGMENT INFORMATION 

We principally operate in the business segment described in Note 1. Pursuant to Codification Topic 280, 

Segment Reporting, we operate in one reportable business segment, that being the development, acquisition, 
manufacture and sale of products that improve the health and productivity of dairy and beef cattle. Almost all of our 
internally funded product development expenses are in support of such products. The significant accounting policies 
of this segment are described in Note 2. Our single operating segment is defined as the component of our business for 
which financial information is available and evaluated regularly by our chief operating decision-maker in deciding 
how to allocate resources and in assessing performance. Our chief operating decision-maker is our President and CEO. 

Sales of the First Defense® product line aggregated 97% and 94% of our total product sales during the years 

ended December 31, 2018 and 2017, respectively. Our primary customers for the majority of our product sales (87% 
and 82% during the years ended December 31, 2018 and 2017, respectively) are in the U.S. dairy and beef industries. 
Product sales to international customers, who are also in the dairy and beef industries, aggregated 13% and 15% of our 
total product sales during the years ended December 31, 2018 and 2017, respectively. 

19. RELATED PARTY TRANSACTIONS 

Dr. David S. Tomsche (Chair of our Board of Directors) is a controlling owner of Leedstone Inc., a domestic 

distributor of ImmuCell products (the First Defense® product line and CMT) and of J-t Enterprises of Melrose, Inc., 
an exporter. His affiliated companies purchased $527,819 and $610,073 of products from us during the years ended 
December 31, 2018 and 2017, respectively, on terms consistent with those offered to other distributors of similar 
status. We made marketing-related payments of $12,380 and $8,118 to these affiliated companies during the years 
ended December 31, 2018 and 2017, respectively, that were expensed as incurred. Our accounts receivable (subject to 
standard and customary payment terms) due from these affiliated companies aggregated $16,283 and $14,176 as of 
December 31, 2018 and 2017, respectively. 

20. EMPLOYEE BENEFITS 

We have a 401(k) savings plan (the Plan) in which all employees completing one month of service with the 

Company are eligible to participate. Participants may contribute up to the maximum amount allowed by the Internal 
Revenue Service. We currently match 100% of the first 3% of each employee’s salary that is contributed to the Plan 
and 50% of the next 2% of each employee’s salary that is contributed to the Plan. Under this matching plan, we paid 
$104,843 and $87,521 into the plan for the years ended December 31, 2018 and 2017, respectively. 

21. SUBSEQUENT EVENTS 

We have evaluated subsequent events through the time of filing on March 22, 2019, the date we have issued this 

Annual Report on Form 10-K. As of such date, there were no material, reportable subsequent events.
