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. We support the dairy and beef industries’ purpose to produce nutritious proteins efficiently while ensuring food quality and safety. 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 treatment paradigm with Re-Tain®, a novel product we are developing to treat this most significant cause of economic loss to the dairy industry.
ImmuCell Corporation
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 achieved FDA approval for four out of five of the significant Technical Sections required for product approval, and we are preparing to make a third submission of the fifth Technical Section. 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.
From the first quarter of 2016 through the second quarter of 2021, we issued an aggregate of 4,553,017 shares of common stock, raising gross proceeds of approximately $26.7 million in six separate transactions. 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. Net of debt issuance costs, we had approximately $10.2 million in outstanding debt under five different credit facilities as of December 31, 2022 compared to approximately $9.1 million as of December 31, 2021. This new equity and debt capital has been, and is being, used to increase the production capacity for the First Defense® product line and complete the development of Re-Tain® without relying on funding from a partner or licensee, thereby keeping control over all product rights and future revenues.
During the past seven years, we have funded our operations, constructed an FDA regulated Drug Substance manufacturing facility for Re-Tain® and invested capital to increase our production capacity for the First Defense® product line. We have also initiated another capital investment to bring the formulation and aseptic filling capabilities for Re-Tain® in house in order to end our present reliance on an outside contractor. The following table displays the changes in the balances of certain accounts over this period (in thousands, except for percentages):
As of December 31, $ (Decrease) Increase Over

Production Capacity Increase and Product Contamination
During 2018, it became clear that demand for Tri-Shield First Defense® was outpacing production. In response to this increasing demand, we began a series of investments during 2019 to increase our production capacity for the First Defense® product line to approximately $30 million per year. The necessary facility expansions and new equipment needed to increase production capacity were in place by the end of 2022. See PART I: ITEM 7 - MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, “Liquidity and Capital Resources”, for more detail about our production capacity.
ImmuCell Corporation
Unfortunately, as this increased production capacity was coming online, a product contamination event was detected by standard in-process quality control testing around the end of the third quarter of 2022. Contamination events during 2022 (largely this one around the end of the third quarter) resulted in a total charge to costs of goods sold of approximately $588,000. We took immediate steps to address the contamination, and production ran without issue during the balance of the fourth quarter of 2022. Then during the first quarter of 2023 our standard in-process quality control testing detected a second contamination event. The related charge to costs of goods sold during the first quarter of 2023 is expected to be up to approximately $200,000, of which approximately $114,000 worth of product remains under evaluation. In response, we have slowed down our production output as we take the necessary steps to assess and remediate the issues and perform a deep sanitization of our facilities and process equipment to ensure that any product that is put to market meets all quality standards. We believe that the ongoing implementation of our capacity expansion plans and the corrective actions being taken in response to these contamination events should allow us to operate at the higher level of production output going forward without further significant contaminations. We are working diligently to address the situation and believe we are taking the appropriate steps to emerge from this problem stronger with the production capacity in place to produce approximately $30 million of product per year going forward.
This production slowdown during the first quarter of 2023, has, in part, caused an increase in the amount of our order backlog from approximately $2.5 million as of December 31, 2022 to approximately $8 million as of March 10, 2023. However, we do not believe this backlog number is highly relevant anymore as it includes very old orders, redundancy in demand and orders that may be cancelled. We expect to report reduced sales during the first quarter of 2023 and a large backlog as of March 31, 2023. We are on track to produce approximately $3.2 million to $3.4 million of product during the first quarter of 2023, which is approximately 56% less than our $7.5 million quarterly production target. While this is less than we need, our remediation efforts are beginning to work as we cautiously come back into production. Due to the loss in earned gross margin that is being incurred during the first quarter of 2023, we have made the decision to defer, for the time being, completion of the incremental planned investment to increase our production capacity further to approximately $40 million per year.
The increase in sales demand for First Defense® is both exciting and challenging for us. One view is that we are operating with short supply caused largely by contamination events on the First Defense® side, while not yet achieving FDA approval of Re-Tain®. However, the other view is that we are approaching both approximately $30 million in annual production capacity for First Defense® (with a flex option to get to approximately $40 million per year in the future) while also advancing to the final stages of a very significant FDA product development initiative.
Animal Health Products
The First Defense® product line is manufactured from hyperimmunized 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, coronavirus and rotavirus (three leading causes of scours). A single dose of our product provides a measured level of protection proven to reduce mortality and morbidity. Our pre-formed antibody products provide Immediate Immunity™ during the first few critical weeks of life when calves need this protection most. Studies have shown 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. Our capsule format of this product, which requires no mixing, is stored at room temperature. The gel tube formats of this product require refrigeration in accordance with product label indications. We are the market leader (in terms of both unit volume and dollar sales) when compared to other calf-level scours preventatives and have greater market potential as we gain market share from the dam-level (pre-calving scour vaccines) competitors. The third quarter of 2021 marked the 30th anniversary of the original USDA approval of this product in 1991. During the third quarter of 2022, our cumulative sales of First Defense® since inception exceeded 30 million doses.
ImmuCell Corporation
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, which is the leading cause of death in preweaned calves. Our Beyond Vaccination® marketing campaign focuses on providing antibodies without vaccination. A 100% vaccine protection rate is biologically impossible. The First Defense® product line removes the variability associated with a scour vaccine response and instead provides a measured level of pre-formed antibodies, protecting each calf with an equal level of scours protection. There is a strong link between how we sell our product and the challenges we face in producing it. We know better than most how variable a cow’s response is to any vaccine. We see this in every batch of First Defense® that we produce. The value in First Defense® is that we adjust for this variability by standardizing the antibody content, as needed, so the newborn is given a steady, equal level of protection with each dose. This technology removes a producer’s reliance on variable vaccine responses to generate passive antibody protection and instead protects every calf equally with a measured dose of Immediate Immunity™ against the most common scour pathogens. Plus, an effectively treated calf is much less likely to require expensive antibiotic treatments and build antibiotic resistance. We are the only manufacturer within the scour prevention space offering polyclonal multi-pathogen antibodies. The market is learning that the best preventative for scours may not be a vaccine, and we are continuing to educate the market about the health benefits of a measured dose of pre-formed antibodies.
The 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 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 rotavirus antibodies in a single-dose gel tube delivery format. This unique breadth of claims further differentiates our product from calf-level competitive products on the market that contain only one or two of these label claims. The unique virus-like particle (VLP) technology that is used in our production process increases rotavirus titers in colostrum to a level much greater than traditional vaccine technology can. Because it is possible that some farms may not have (or perceive to have) a rotavirus problem, we are continuing to sell the bivalent formats of the First Defense® product line as options for customers.
Historically, the most common tool to help combat scours has been to vaccinate the mother cow (dam) with a scours vaccine and deliver the antibodies that she produces in her milk to the 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. We are competing effectively against these dam-level vaccine products. Our marketing campaign, Beyond Vaccination®, emphasizes that by delivering Immediate Immunity™ directly to the calf via the First Defense® product line, producers can reduce stress-causing injections to the cow. 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 the First Defense® product line, 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.
Preventing newborn calves from becoming sick helps them to reach their genetic potential and reduces the need to use treatment antibiotics later in life. 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 to invest in additional sales and marketing efforts to help us introduce the expanding First Defense® product line to new customers. Our communications campaign continues to emphasize how the unique ability of the First Defense® product line to provide Immediate Immunity™ generates a dependable and competitive return on investment for dairy and beef producers.
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 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.
ImmuCell Corporation
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 acquired private label manufacturing rights covering a feed supplement product sold by Genex Cooperative, Inc. of Shawano, Wisconsin. This product was discontinued by mutual agreement during the first quarter of 2022. Annual sales of this private label product were less than $170,000 during each of the years ended December 31, 2021 and 2020.
Sales and Markets
Our sales and marketing team consists of one vice president, one commercial research and technical services veterinarian, one commercial leader of stakeholder engagement, one director of marketing and customer service and eight regional sales managers. 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. 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. 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. 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. Despite the market volatility affecting both milk prices and feed costs, we expect to continue to increase our sales over the long term (despite a drop in 2022).
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 $27.9 million per year. With the additional claim for our new product (Tri-Shield First Defense®) against rotavirus, we are now also 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. We estimate that the total domestic addressable market (both calf and dam levels) is approximately $74.5 million per year.
Based on market share information that we purchase from the leading source of this data for the animal health sector, we are gaining market share in the United States year after year. We aim to continue these market share gains in both the dairy and beef segments. Our share of the market (calculated on the basis of calves treated) of the scour preventative products administered at the calf-level was approximately:
34%
36%
41%
43%
44%
Our share of the market (calculated on the basis of calves treated) of both products administered at the calf-level and vaccines administered to the dam prior to calving (adjusting for two doses of dam-level scour vaccines required for primary vaccination of first-calf heifers) was approximately:
10.3%
11%
12.6%
13.2%
14.4%
We continue our efforts to grow sales of the First Defense® product line in North America, where there are approximately 40 million dairy and beef cows in the United States and approximately 4.5 million dairy and beef cows in Canada. We believe that significant market opportunities exist in other international territories. 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. 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, potentially making it more difficult or costly for us to generate and sustain sales volumes at profitable margins in these markets.
ImmuCell Corporation
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. We are working with Medexx to expand our business in South Korea to include the registration of Tri-Shield First Defense®. The business in Japan is currently not active, but we are working to resume sales in this territory. 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 (no sales have yet been achieved under this contract) and covering Iran with Senikco, LLC of Laguna Niguel, California during the fourth quarter of 2016 (sales have been initiated under this contract). We are investigating the requirements to sell the First Defense® product line in Mexico, Pakistan and Israel.
With Re-Tain®, we are working to expand our product portfolio to include an intramammary infusion for the treatment of subclinical mastitis in lactating dairy cows. Mastitis is inflammation of the mammary gland typically associated with a bacterial infection. It is estimated to cost the U.S. dairy industry approximately $2 billion in economic harm per year. It is the most costly and common disease affecting the dairy industry. This illness is categorized as either clinical mastitis or subclinical mastitis. Clinical mastitis infections cause visibly abnormal milk which cannot be sold. On the other hand, subclinical mastitis infections do not cause any visible changes in milk or udder appearance, making it difficult to detect. Most mastitis cases treated today are those that reach the clinical stage even though it is understood that clinical cases are only the tip of the mastitis iceberg. Milk from cows with subclinical mastitis can still be sold if not treated with traditional antibiotics. Milk from cows treated with traditional antibiotics must be discarded for the duration of the treatment and for 1.5 to 4 days after the last treatment, depending on the antibiotic that was used. The cost of that milk discard along with the stress and risk in moving the cow to the hospital pen is thought to be the primary reasons more subclinical mastitis cases are not treated today. However, the cascade of negative events triggered by subclinical mastitis for both the dairy producer and the milk processor are significant. These include lower milk production (some have estimated approximately 1,500 pounds of lost milk, or about $270 at $18.00 per hundredweight per infected cow per lactation), higher rates of clinical mastitis, lower conception rates, increased abortions, increased cull rates, reduced or foregone milk quality premiums, shorter shelf life for fluid milk, and both lower yields and less flavor for cheese. Cows with subclinical mastitis maintain a reservoir of infection within the herd and increase exposure of healthy cows to contagious pathogens. Subclinical mastitis also increases the risk of various quality defects on a variety of final dairy products.
The active ingredient in Re-Tain® is pharmaceutical-grade Nisin-A. FDA approval for this drug would establish an entirely new class of anti-infective that is different from those currently available to treat mastitis. This new class, called bacteriocins, are anti-microbial polypeptides with no resistance risk for human health. Bacteriocins selectively target Gram+ bacteria, the same bacteria that commonly cause mastitis. We expect Re-Tain® will be the first FDA-approved intramammary treatment for subclinical mastitis without a milk discard or meat withhold. This gives us the opportunity to revolutionize the way mastitis is treated, since Re-Tain® is specifically designed to treat ahead of clinical signs without a milk discard and, as a result, cows can reach their peak milk production and not be sent to the hospital pen.
Re-Tain® 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. We estimate that the approximate cost to the U.S. dairy industry of this discarded milk may be around $300 million per year. These high milk discard costs associated with traditional antibiotic treatments lead producers to only treat mastitis after clinical signs develop. The Re-Tain® label will be for subclinical mastitis (not clinical). Without a milk discard cost, we expect producers to be more motivated to identify and treat cows at the subclinical stage. 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.
It is difficult to accurately estimate the potential size of the subclinical mastitis market because presently this disease is largely left untreated. We believe that approximately 20% to 40% of the U.S. dairy herd is infected with subclinical mastitis at any given time. 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. Rarely is an industry revolutionized overnight. Getting producers to change protocols to make subclinical mastitis treatment a standard and routine procedure is going to take initiative, but we believe producers are eager for something new and better since the FDA has not approved an intramammary treatment within the last 20 years. Similar market opportunities are likely to exist outside the United States. We believe the use of Re-Tain® could be expanded, with additional data and regulatory approval, to support treatment late in lactation and possibly for clinical stage mastitis. We also believe there may be a market for Re-Tain® in small ruminants, where the majority of mastitis cases are caused by strep-like organisms aligned with our effectiveness data.
ImmuCell Corporation
Based on consultations with industry experts and key opinion leaders, we have opted to carefully control the launch of this novel product over the first 18 to 24 months after FDA approval, as we seek to transform the way that mastitis is treated in the dairy industry over the long term. Our goal is to help early adopters select treatment candidates, develop easy to use protocols, optimize treatment results and realize a positive return on their investment. We intend to limit initial distribution of Re-Tain® to a level that enables our sales team to select the optimal dairy farms at which to introduce Re-Tain® and to limit the initial numbers of participating farms so that the desired levels of support and guidance relating to effective usage of Re-Tain® can be provided with our available resources. Our overarching objective is to minimize the risk of early stage unsatisfactory outcomes that could harm the longer term prospects and market acceptance of Re-Tain®. This strategy also reduces the amount of inventory that we would need to build at risk before regulatory approval is achieved, and it reduces the amount of cash we would need to spend to purchase inventory from our contract manufacturer before our in-house aseptic filling services are approved by the FDA. This strategic choice means that we have elected not to pursue an alternative strategy that might have maximized short-term, initial sales quickly through a mass market approach where we provide product to distribution and let them sell it to as many farms as possible. While we are dedicated to increasing our sales revenue, we must consider the damage a mass market strategy could cause to the long-term value of the product. We have seen products sold by much larger companies that were substantially damaged by such failed market launch strategies. We continue to develop detailed launch plans, focusing on the readiness of dairy operators to successfully introduce Re-Tain® to their herds. We believe that these prudent steps, while potentially leading to lower initial Re-Tain® revenues, may create a smooth and successful launch and could safeguard the longer term performance of our investment in Re-Tain®.
Because Nisin is a naturally occurring bacteriocin that is not used in human medicines, it could alleviate some of the social and public health concerns that the widespread use of antibiotics encourages the growth of antibiotic-resistant bacteria. For example, there is a fear that the possible overuse of antibiotics in livestock undermines the effectiveness of these 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 has expressed a commitment 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. By reducing the risk of antibiotic residues and slowing the development of antibiotic-resistant organisms, we believe that we can improve food quality and preserve medically important antibiotics for human disease treatment. This current environment is 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 to use treatment antibiotics later in a calf’s life.
In the big picture, we are introducing an entirely new class of antimicrobials as an animal drug, a bacteriocin, that does not promote resistance against antibiotics used in human medicine, making it more socially responsible. As the great NHL hockey player, Wayne Gretzky, is known to have said, “I skate to where the puck is going to be, not where it has been.” This is motivational to us. We believe our product fits very well with where the industry is going to be in the coming years. Sustainability objectives of the industry require that less antibiotics be used in food producing animals, yet a new product to treat mastitis has not been developed in years (other than new formulations of the same old stuff). The over-use of antibiotics that are medically important to human healthcare is a growing concern of our society and an active issue with the FDA, largely because of the growing evidence that this over-use contributes to antibiotic resistance. The industry could keep treating this very significant disease with traditional antibiotics, but it takes innovation to bring a bacteriocin like Nisin to market. Re-Tain® will, when introduced, offer a needed alternative to these traditional antibiotics. We believe that societal animal welfare objectives will put more and more pressure on the industry to treat cows with subclinical infections.
We expect the Drug Substance production facility that we constructed for approximately $20.8 million to have initial annual production capacity sufficient to meet at least $10 million in sales of Re-Tain® at current production yields. This production capacity estimate does not yet reflect any inventory build strategies or ongoing yield improvement initiatives. Expansion of the estimated annual capacity of the Drug Substance facility beyond approximately $10 million (without factoring in potential yield improvements) would require relocation of the Drug Product formulation and aseptic filling module to another facility, or the acquisition and equipping of other Drug Substance production facilities or adopting alternative manufacturing strategies.
In an effort to provide greater visibility into the launch of Re-Tain®, we have expanded Note 17, “Segment Information”, to the accompanying audited financial statements to now display a break-out of our financial results among the following three components of our business: i) Scours, ii) Mastitis and iii) Other. This will allow investors to see our progress with both product lines. We generally do not provide financial projections, as we know such projections can prove to be materially inaccurate. However, in this case, we are providing a high-level projection for Re-Tain® that under our controlled launch plan strategy, we estimate that we can achieve sales of approximately $1 million in 2024 and then achieve approximately twice that in 2025. This assumes FDA approval is achieved and that product launch is initiated around the end of 2023. If we are successful with this launch strategy, we would aim to grow this curve in 2026 and after. We believe this strategy lends itself to a more gradual adoption curve but higher and more sustainable sales over the long-term. Actual sales results will vary from these projections up or down.
ImmuCell Corporation
Through continued growth in sales of the First Defense® product line, and as additional resources are dedicated to production, sales, marketing and technical services, it is our objective to exceed our total product sales of approximately $19 million achieved during the year ended December 31, 2022 as soon as possible. Our longer-term goal is to exceed $35 million of annual total product sales as soon as possible during the five-year period after the market launch of Re-Tain®.
Product Development
Most 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 23-year period that began on January 1, 2000 and ended on December 31, 2022, we invested an aggregate of approximately $25.2 million (excluding depreciation and the capital cost of our Drug Substance production facility) in the development of this product. This estimation 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.
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 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. A much less pure preparation of our active ingredient, Nisin, is commonly used as a food preservative and has been given “Generally Regarded as Safe” (GRAS) status by the FDA. Our Nisin technology includes patented processing and purification methods to achieve pharmaceutical-grade purity.
During 2004, we entered into a product development and marketing agreement with Zoetis (formerly Pfizer Animal Health, a division of Pfizer, Inc.) 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. Further, we believe that such a premium-priced product will be used selectively, which reduces the risk of cheese interference and is consistent with modern “precision dairying” practices that discourage the indiscriminate use of drug treatments. Among the measures that we intend to deploy will be detailed guidance on limiting the portion of a herd that is treated with Re-Tain® at any one time in order to avoid concentration levels in the milk that could lead to the rejection of the contents in a cheese tank.
Subclinical mastitis, and the study required to achieve an effectiveness claim for it, is defined under the FDA/Center for Veterinary Medicine Guidance #49: Target Animal Safety and Drug Effectiveness Studies for Anti-Microbial Bovine Mastitis Products (Lactating and Non-Lactating Cow Products). Trial eligibility requires both pretreatment samples to be positive for the mastitis pathogen (except for Staphylococcus aureus and Streptococcus agalactiae, where a single pretreatment sample qualifies a cow for enrollment). For all pathogens, both samples taken between 14 and 28 days post treatment (and at least 5 days apart) must be negative to be judged a cure. These conservative criteria generally result in enrolling cows with chronic subclinical disease, which rarely self-resolves.
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 a perpetual, exclusive license with the Baylor College of Medicine covering the underlying rotavirus vaccine technology used to generate the specific antibodies for use with animals. 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 initiated sales in Canada through our in-country distributor during the fourth quarter of 2019. 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 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 working to expand our product development pipeline of antimicrobials that can be used as alternatives to traditional antibiotics through expansions of our Nisin technology and yield improvements. 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. Most, if not all, 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, 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. Our Nisin A is produced from our high-yielding, proprietary L. lactis strain and purified to a high level, providing us with a level of protection over a competitor that might try to develop a similar product.
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, the First Defense® product line is the only calf-level product that 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 immediately after birth and are not negatively affected by 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 competing 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 this vaccine product. There is no nutritional or health 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 good calf health. Because the antibodies in our product would likely work to inactivate a modified-live virus 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 by colostrum. Our product is priced at a premium to Calf-Guard®.
During the fourth quarter of 2016, Merck launched a new competing product into this market space. This product (BOVILIS® Coronavirus) is a modified-live virus intranasal vaccine that carries a claim against coronavirus only. Around the end of 2019, Elanco Animal Health gave notice to the market that it had discontinued the manufacture of its competing products, Bovine Ecolizer® and Bovine Ecolizer + C20, and subsequently exited the market during the first quarter of 2021. This product was the smallest of our three significant calf-level competitors. During the first quarter of 2023, we learned that some of our dam-level scour competitors were tight in supply and may not be able to meet all of their marketing demand.
When compared to the other USDA-approved calf-level scours preventatives, we lead in both sales dollars and calves treated within the U.S. market. This product category is comprised of the three primary brands discussed above that are given either orally or intranasally to newborn dairy and beef calves immediately after birth. With the rotavirus claim for our product (Tri-Shield First Defense®), we are now also 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 measured 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, manufacturing, managerial and sales and marketing personnel, to develop and effectively produce and market proprietary technologies and products. We need to obtain USDA, FDA or foreign approvals for new products to effectively promote and market our products. We must have available properly licensed, efficient and effective raw material and finished product manufacturing resources to continue to profitably sell our current products. We currently compete on the basis of product performance, price, distribution capability and customer support. We continue to monitor our network of independent distributors to maintain our competitive position.
ImmuCell Corporation
Intellectual Property
We own a broad collection of registered and unregistered intellectual property rights relating to our research, products and processes. These rights include patents, copyrights, trademarks, trade dress, trade secrets, know-how and other intellectual property rights in the United States and other countries. We believe the ownership of our intellectual property rights is an important factor in our business and that our success depends in part on such ownership. We also rely heavily on the innovative skills, technical competence and marketing abilities of our personnel. The Nisin A that is produced from our proprietary strain of L. lactis is an essential component of our intellectual property covering Re-Tain®. We enter into and rely on confidentiality and proprietary rights agreements with our employees, contractors and business partners to protect our trade secrets, proprietary developments and confidential information.
We own: (a) U.S. Patent No. 6,794,181 entitled “Method of Purifying Lantibiotics”, which covers a manufacturing 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 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 development. 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 processes. 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 registrations in the United States, Canada and Iran. 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, DUAL-FORCE, TRI-SHIELD and RE-TAIN. We also own U.S. registrations claiming rights in the color blue for our blue gel and blue bolus FIRST DEFENSE products. The United States Patent and Trademark Office refused registration of our IMMEDIATE IMMUNITY trademark, which we use in connection with marketing of all of our products, on the grounds that the mark is generic. Rather than appeal this finding, we are continuing to build our common law rights in the brand as we do with other brands from time to time. 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.
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 Re-Tain® 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 competing 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 74 employees (including 7 part-time employees) in comparison to 67 employees (including 7 part-time employees) approximately a year ago. Approximately 48.4 full-time equivalent employees are engaged in quality and manufacturing operations, 13.5 full-time equivalent employees in sales and marketing, 6.7 full-time equivalent employees in product development activities (primarily supporting facility maintenance and operation, regulatory filings and commercial scale-up for Re-Tain®) and 5.4 full-time equivalent employees in finance and administration. As needed, we augment our staff with contracted temporary employees. All of our employees are required to execute non-disclosure and invention assignment agreements (and some are required to execute non-compete 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.

ITEM 1A. RISK FACTORS
ITEM 1A - RISK FACTORS
Financial Risks
Gross margin on product sales: One of our goals is to achieve a gross margin (before related depreciation expenses) as a percentage of total sales approaching 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 the First Defense® product line. Gross margins generally improve over time, but this anticipated improvement may not be realized for Re-Tain®. Many factors discussed in this report (including inflation and the COVID-related and other cost increases, supply-chain disruptions and the rising price of oil and other commodities and supplies) impact our costs of goods sold. There is a risk (which was experienced during 2022) 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. There is a risk that our plans to maintain or improve our gross margin may not be realized due to cost increases, additional manufacturing contamination events, the inability to raise our selling prices, or any combination of these factors.
Exposure to interest rates and debt service obligations: Rising interest rates could negatively affect the operating costs of dairy and beef producers and thus put further financial pressure on an already stressed business sector, which could indirectly, but materially and adversely, affect our business. We removed the direct aspect of this particular exposure to our business by refinancing our bank debt with fixed rate notes at 3.50% per annum during the first quarter of 2020. The $2 million in additional mortgage debt we secured during the first quarter of 2022 bears interest at the fixed rate of 3.58% per annum. The two State of Maine loans aggregating $900,000 bear interest at the fixed rate of 5% per annum. Increasing interest rates would negatively impact the cost of any future borrowings. The additional debt we incurred to fund our growth objectives has significantly increased our total debt service costs. We are obligated to make principal and interest payments aggregating approximately $1.4 million during both of the years ending December 31, 2023 and 2024. See Note 10 to the accompanying audited financial statements for more details about our debt. A decline in sales or gross margin, coupled with this debt service burden, could impair our ability to fund our capital and operating needs and objectives.
Debt covenants: Our bank debt is subject to certain financial covenants. We are required to meet a minimum debt service coverage (DSC) ratio of 1.35, which is measured annually. Our actual DSC ratios were 0.44, 2.68 and 2.03 for the years ended December 31, 2022, 2021 and 2020, respectively. There can be no assurance that we can exceed that required level in subsequent years. By negotiation with the bank in connection with a mortgage debt financing during the first quarter of 2022, the required minimum DSC ratio was reduced to 1.0 for the year ending December 31, 2022. Subsequently, our bank waived the required compliance with this rate for the year ended December 31, 2022. During the first quarter of 2023, the DSC ratio covenant for the year ending December 31, 2023 was waived by our bank. Instead, we are required to meet a minimum DSC ratio requirement of 1.35 for the twelve-month periods ending June 30, 2024, September 30, 2024 and December 31, 2024 and then again annually after that. If we are unable to achieve the required DSC ratio going forward or reach a favorable agreement with our bank regarding that requirement (including an amendment to or waiver of such requirement), we would be in violation of that covenant, which could result in unfavorable amendments to the terms of our bank debt or have other adverse impacts on our business and results of operations.
Currency exchange fluctuation: We do not believe that currency exchange rates have had a significant effect on our revenues and expenses. However, future increases in 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. The current devaluation of the dollar makes Euro-based purchases more expensive for us.
Inflation: Inflation is having a material and adverse impact on almost all supplies we purchase and labor we hire and retain. Continuing or increasing inflationary trends could materially reduce our gross margin on product sales if we are unable or unwilling to impose offsetting price increases on our customers. According to the Consumer Price Index for All Urban Consumers (CPI-U) during the year ended December 31, 2022, the all items index increased 6.5% before seasonal adjustment.
Projection of net (loss) income: 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 deeper operating losses. The timing of FDA approval of Re-Tain® will have a material impact on our net (loss) income until sufficient commercial sales are generated and sustained.
ImmuCell Corporation
Risks associated with our funding strategy for Re-Tain®: The inability to maintain adequate cash and liquidity to support the commercialization of Re-Tain® is a risk to our business. Achieving FDA approval of our pharmaceutical-grade Nisin produced at commercial-scale is the most critical action remaining in front of us on our path to U.S. regulatory approval of Re-Tain®. Having completed the construction and equipping of the Drug Substance 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 and maintain this facility until commercialization. Absent sufficient sales of Re-Tain® at a profitable gross margin, we would be required to fund all debt service costs from available cash and sales of the First Defense® product line, which would reduce, and could eliminate, our expected profitability going forward and significantly reduce our cash flows.
Uncertainty of market size and product sales estimates: Estimating the size of the total addressable market and future sales growth potential for our First Defense® product line is based on our experience and understanding of market dynamics but is inherently subjective. Estimating the size of the market for any new product, such as Re-Tain®, involves more uncertainties than do projections for established products. We do not know whether, or to what extent, our products will achieve, maintain or increase market acceptance and profitability. Some of the uncertainties surrounding Re-Tain® include the product’s effectiveness against currently prevalent pathogens, market acceptance, the effect of a premium selling price on market penetration, cost of manufacture, competition from new and existing products sold by substantially larger competitors with greater market reach and promotional resources and other risks described under “Product Risks” - “Sales risks pertaining to Re-Tain®” below. Since Re-Tain® is a novel approach to treating mastitis, there are many uncertainties with regards to how quickly and to what extent we can develop the subclinical mastitis treatment market. We believe that polypeptide antimicrobial technology may be viewed positively (relative to traditional antibiotics). If realized, this may offset some of these risks and result in better overall market acceptance.
Net deferred tax assets: The realizability of our net 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 net deferred tax assets that significantly increased our net loss in comparison to other periods. This non-cash expense could be reversed, and this valuation allowance could be reduced or eliminated, if warranted by our actual and projected profitability in the future. We will continue to assess the need for the valuation allowance each quarter.
Product Risks
Product risks generally: We set objectives for our products that we believe we can achieve, but the achievement of such goals is not a certainty. 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 lower margins and/or an order backlog that could adversely affect our customer relationships and operating results. First Defense® is sold, and we expect Re-Tain® to be sold, at significant price premiums relative to competitive products. There is no assurance that we will continue to achieve market acceptance of the First Defense® product line, or achieve and sustain market acceptance of Re-Tain®, 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 manufacture and sale. As we bring Re-Tain® to market, these risks could be heightened by the additional uncertainties associated with introducing a new product requiring a shift in customer behavior.
Contamination events in our production process: Around the end of the third quarter of 2022 and during the first quarter of 2023, we experienced certain contamination events in our production process. We are at risk of further such production contaminations resulting in more scrapped inventory if we do not achieve an adequate level of sanitization and quality controls in our production process from farms to finished goods. These risks could result in a slowdown or shutdown of our production capacity if not managed effectively.
Sales risks pertaining to Re-Tain®: Actual or prospective Re-Tain® customers may decide to discontinue, reduce or avoid usage of Re-Tain® due to the following risks:
1) A rejection of a tank of milk by a positive milk inhibitor test because too much of the milk in a bulk tank is comprised of milk from cows being treated with Re-Tain®, when tested randomly for inhibitors by a milk hauler.
2) A failed or stalled cheese tank occurs when our recommended on-farm limit of 3% to 5% of milk from cows being treated with Re-Tain® is exceeded or not effectively diluted through the milk transportation and collection system, if a cheese starter culture is used that is susceptible to Nisin.
3) Producers’ current practice generally is to treat only clinical mastitis, which has the visual indicator of abnormal milk. In order to gain market penetration for Re-Tain®, we will need to change that practice and increase awareness of the importance of treating subclinical disease. This will require the producers’ ability and willingness to diagnose without visual indicators. Users of Re-Tain® could have unsatisfactory treatment outcomes if they lack the equipment needed to measure and monitor somatic cell counts (SCC) of the herd or individual cows (for which data is needed). This risk limits our access to treatment cows because about 40% of farms do not presently access this kind of testing at the cow level, and thus are not good candidates for the use of Re-Tain®.
ImmuCell Corporation
4) Lower than anticipated treatment cure rates could be experienced because the product is administered to cows that we would not identify as the best treatment candidates based on SCC data.
5) Lower than anticipated treatment cure rates could be experienced because the product is administered to cows that are infected with pathogens outside of our label claims.
6) Off-label use of our product in cows infected with clinical mastitis before we have run the required studies and achieved a label claim extension for this disease state, resulting in negative treatment outcomes.
7) Producers either do not choose to use it or might use it improperly, rather than follow our label instructions to administer one dose after each of three consecutive milkings, or they may limit use within the herd in an abundance of caution to avoid the negative outcomes described above.
Reliance on sales of the First Defense® product line: We are 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 profitable during the years ended December 31, 2012, 2013, 2015 and 2016, during the nine-month periods ended September 30, 2017 or during the three-month periods ended March 31, 2019, December 31, 2020, June 30, 2021, September 30, 2021, December 31, 2021 and March 31, 2022 without the gross margin that we earned on sales of the First Defense® product line.
Concentration of sales: Sales of the First Defense® product line aggregated 99% and 98% of our total product sales during the years ended December 31, 2022 and 2021, respectively. Our primary customers for the majority of our product sales (92% and 86% during the years ended December 31, 2022 and 2021, 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 8% and 14% of our total product sales during the years ended December 31, 2022 and 2021, respectively. The concentration of our sales from one product into just two markets (the dairy and beef markets) is a risk to our business. The animal health distribution segment has been aggressively consolidating over the last few years, with larger distributors acquiring smaller distributors. A large portion of our product sales (73% during both of the years ended December 31, 2022 and 2021) was made to two large distributors. A large portion of our trade accounts receivable (69% and 72% as of December 31, 2022 and 2021, respectively) 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 in a manner unfavorable to us.
Production capacity constraints: We invested approximately $3.7 million from 2019 to the first quarter of 2022 to increase our production capacity (in terms of annual sales dollars) for the First Defense® product line from approximately $16.5 million to approximately $23 million based on current selling prices and estimated production yields. During the fourth quarter of 2021, we reached this new, higher level of production output on an annualized basis. While this capacity expansion investment has proceeded very close to budget, there is a risk of cost overruns in our ongoing projects and any future production expansions that we may undertake, and a risk that we will not be able to achieve our production capacity growth objectives on a timely basis, resulting in a continuing or increasing shortfall in supply to the market. The inability to meet market demand for our products is a risk to our business. The historically large backlog of orders, as well as any ongoing order backlog, presents a risk that we could lose customers during this period that are not easily regained thereafter, when our production capacity is expected to meet or exceed sales demand. During 2021, we initiated three additional investments aggregating approximately $4.7 million to increase our annual production capacity for the First Defense® product line to approximately $30 million, which we completed at the end of 2022. We are making initial plans and investments to further increase our production capacity in 2024 and after. Our plan to continue to expand the First Defense® product line requires ongoing review of equipment capacity and utilization across the manufacturing value stream at the 56 Evergreen Drive facility and our leased facility at 175 Industrial Way, as well as assessment of functional obsolescence and reliability of equipment. This review and assessment could identify a need to fund unexpected equipment maintenance or replacement costs.
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 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 Risks
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, with subsequent approvals of line extensions in 2017 and 2018. As a result, our operations are subject to periodic inspection by the USDA, and we are at risk of an unfavorable outcome from such inspections. 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, which could interrupt sales and adversely affect our operating results. Territories outside of the United States may require additional regulatory oversight that we may not be able to meet with our current facilities, processes and resources.
Regulatory requirements for Re-Tain®: The commercial introduction of this product in the United States requires 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 regulatory development process timeline has been extensive (approximately 15 years from when the product rights were returned to us by a former partner in 2007) and has involved multiple commercial production strategies and multiple submissions of the Chemistry, Manufacturing and Controls (CMC) Technical Section. Most recently, we received an Incomplete Letter from the FDA regarding this CMC Technical Section during the third quarter of 2022. The principal issue remaining is a successful pre-approval re-inspection of our manufacturing facility. We are completing preparations for this re-inspection. This clarifies the required path to product approval. To reduce the risk associated with this process, we are working with a qualified contract manufacturer (Norbrook) for alignment of the required validations and Drug Product manufacture and have met with the FDA to clarify filing strategy and requirements. Our CMC Technical Section submission will be subject to a statutory six-month review period by the FDA. We believe we can successfully complete the pre-approval re-inspection inside of this time frame. However, our efforts continue to be subject to inspection and approval by the FDA and other factors outside of our control, and there remains a risk that the required FDA approvals of our product and facilities could be delayed or not obtained. International regulatory approvals would be required for sales of Re-Tain® outside of the United States, and there is a risk that these approvals would be or become too costly to pursue or be delayed or not obtained. Sales in these international territories would also be subject to milk discard and meat withhold restrictions, thereby reducing the competitive advantage of Re-Tain® in those territories.
Economic Risks Pertaining to the Dairy and Beef Industries
The industry data referred to below is compiled from USDA databases.
Cattle count: 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 each year, reaching 94,800,000 as of January 1, 2019 before declining to 93,800,000 as of both January 1, 2020 and January 1, 2021. This count continued to decline to 92,100,000 and to 89,300,000 as of January 1, 2022 and 2023, respectively. Reflecting seasonal trends, this figure was equal to 102,000,000, 101,000,000 and 98,800,000 as of July 1, 2020, 2021 and 2022, respectively. A significant decline in the cattle count could negatively affect the size of our addressable market.
Herd size: Prior to 1957, there were over 20,000,000 cows in the U.S. dairy herd. Prior to 1986, there were over 10,000,000 cows in the U.S. dairy herd. From 1998 through 2021, the size (annual average) of the U.S. dairy herd ranged from approximately the low of 9,011,000 in 2004 to the high of 9,448,000 in 2021. This average declined to 9,402,000 during the year ended December 31, 2022. A significant decline in the herd size could negatively affect the size of our addressable market.
Milk cow price: The all-time high value (annual average) for a milk cow was $1,993 during 2015. Since then, this annual average value steadily declined to $1,205 during 2019 before increasing to $1,300 during 2020 and to $1,363 during 2021. This price for 2022 increased significantly to an average of $1,598, which is a 17% increase over 2021. This price as of January 2023 increased by another 8% to $1,720. A significant decline in the milk cow price could negatively affect the size of our addressable market.
ImmuCell Corporation
Milk price: The dairy market, similar to many others, has been unstable for several reasons including as a result of the pandemic. The price paid to producers for milk has been very volatile. This market volatility, and the resulting impact on our primary end users, could negatively impact our ability to maintain and grow sales at a profitable level. 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 (since these prices were first reported in 1980) during 2014 at $22.34 (peaking at $24.60 in September 2014), which price level has never been repeated. During the year ended December 31, 2020, this average milk price was equal to $18.16, but it was extremely volatile during the year due largely to disruption in demand related to the COVID-19 pandemic. The one-month fluctuation of 73% from a low of $12.14 in May 2020 to $21.04 in June 2020 set an all-time record for variability. The average price for 2021 decreased by 6% to $17.08. This price average increased by 29% to $21.96 during the year ended December 31, 2022. The average price decreased by 15% to $18.61 during the first two months of 2023. The annual fluctuations in this milk price level are demonstrated in the following table:
Average Class III Milk Price During the Years Ended December 31,
(Decrease) Increase
$ 22.34
$ 15.80 (29 )%
$ 14.87 (6 )%
$ 16.17 9 %
$ 14.61 (10 )%
$ 16.96 16 %
$ 18.16 7 %
$ 17.08 (6 )%
$ 21.96 29 %
Feed Costs: 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. An increase in feed costs also has a negative impact on the beef industry and therefore could have a resulting negative impact on our business and results of operations. This ratio varies farm-to-farm based on individual operating parameters. Since this ratio reached 3.24 in 2005, it has not exceeded 3.00. This ratio averaged 1.74 for 2021, amounting to a significant decline of 25% from the 2020 average of 2.32. This average has not been lower since 2012. During 2022, this ratio improved by 10% to 1.92. This ratio dropped to 1.73 in January 2023. The following table demonstrates the annual volatility and the low values of this ratio recently:
Average Milk-To-Feed Price Ratio During the Years Ended December 31,
(Decrease) Increase
2.54
2.14 (16 )%
2.26 6 %
2.42 7 %
2.05 (15 )%
2.25 10 %
2.32 3 %
1.74 (25 )%
1.92 10 %
Market volatility: 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. Given our focus on the dairy and beef industries, the volatile market conditions and the resulting financial insecurities of our primary end users are risks to our ability to maintain and grow sales at a profitable level. These factors also heighten the challenge of selling premium-priced animal health products (such as Tri-Shield® and Re-Tain®) into the dairy market.
Small Size of Company
Dependence on key personnel: We are a small company with 74 employees (including 7 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, which could be even more challenging in the present very difficult labor market. Our competitive position will be highly influenced by our ability to attract, retain and motivate key scientific, manufacturing, managerial and sales and marketing personnel. We will require increased staffing levels to operate our expanded First Defense® production capacity and to operate our Re-Tain® production facility. The cost of attracting and retaining the needed additional personnel in this current job market and inflationary environment could adversely affect our margins and profitability.
ImmuCell Corporation
Reliance on outside party to provide certain services under contract for us: 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. One example of this outside reliance is Norbrook, our Drug Product (DP) contract manufacturer. Because Norbrook has elected to terminate its supply agreement with us effective as of the end of 2022 (with final deliveries anticipated during the middle of 2023), we are investing approximately $4 million to construct and equip our own DP formulation and aseptic filling capability for Re-Tain® inside our existing Drug Substance facility. Due to the loss in gross margin during the first quarter of 2023 caused by the slowdown in production output necessary to remediate a product contamination event, we have decided to defer spending of approximately 42% of these funds for the time being. We face the risk of potential supply interruption and adverse effects on the market launch of Re-Tain® if we do not effectively manage the end of the DP supply provided from our contract manufacturer for orders scheduled for delivery during the second half of 2023 (with product expiries during the second half of 2025) to align with the new supply from our own formulation and aseptic filling facility, which we currently expect to be operational during 2025. The objective of this investment is to end our reliance on an outside party to perform these services for us. Actual project costs could exceed our current estimates. Completion of this project could be delayed due to a number of factors outside our control, including delays in equipment fabrication, equipment delivery or facility construction. In addition, there is a risk that we fail to achieve regulatory approval of the new facility or that such approval is delayed or requires significant additional expenditures to obtain.
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 and sales/distribution capabilities than we do, including greater ability to withstand adverse economic or market conditions and declining revenues and/or profitability. Merck and Zoetis, among other companies, sell products that compete directly with the First Defense® product line in preventing scours in newborn calves. The scours product sold by Zoetis sells for approximately half the price of our product, although it does not have an E. coli claim (which ours does). With Tri-Shield®, we can now compete more effectively against vaccines that are given to the mother cow (dam) to improve the quality of the colostrum that she produces for the newborn calf. Elanco, Merck and Zoetis provide these dam vaccine products to the market. There are many companies competing in the mastitis treatment market, most notably Boehringer Ingelheim, Merck and Zoetis. The subclinical mastitis products sold by these large companies are well established in the market and are priced lower than what we expect for Re-Tain®, 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 (unlike our product which carries zero milk discard and zero milk withhold claims). There is no assurance that our products will compete successfully in these markets. We may not be aware of other companies that compete with us or intend to compete with us in the future.
Global Risks
Impact of global COVID-19 pandemic and Russia’s unprovoked military invasion of Ukraine: We are facing significant production constraints, supply disruptions and inflationary increases which appear to have been caused, in large part directly or indirectly, by the pandemic and Russia’s unprovoked military invasion of Ukraine. The extent and duration of the negative impact of the pandemic on the economics of our customers and on the demand for our products going forward are very difficult to assess. The dairy market, similar to many others, has been unstable as a result of the pandemic. The price paid to producers for milk has been very volatile. The Class III milk price has been extremely volatile during the pandemic. Initially, stay at home orders disrupted the food service supply system as schools closed and restaurants were shut down. In response, producers were forced to reduce the supply of milk to the market by drying off cows early, culling cows from the herd and dumping milk, among other tactics. Market conditions have improved somewhat, but this volatility remains a concern. Additionally, like most input costs, the cost of grain and other feed is rising, which puts a strain on the profitability of our customers. There is also economic uncertainty for beef producers, as the supply chain is interrupted or otherwise adversely affected due to closures of processing plants and reduced throughput. This is a very unusual situation for farmers that work so hard to improve production quality and efficiency in order to help feed a growing population with high-quality and cost-effective proteins. The pandemic has created risk and continues to create uncertainty and challenges for us. The emergence of the Delta and Omicron variants and the resulting rising number of positive cases during the latter part of 2021 and into 2022 has been a more recent concern. The pandemic has created or contributed to global supply-chain disruptions and has affected international trade, while creating a worldwide health and economic crisis. While presently there are some indications that suggest the situation may be improving, the full impact of this viral outbreak on the global economy, and the duration of such impact, remains very uncertain at this time. Stock market valuations have declined and recovered somewhat but remain very volatile. Inflation has increased significantly, and tax rates may increase. There is a risk of a period of economic downturn, the severity and duration of which are difficult to know. Prior to the pandemic and the responsive federal economic stimulus programs, many feared the United States had taken on too much national debt. Now the debt load is significantly higher. A combination of the conditions, trends and concerns summarized above could have a corresponding negative effect on our business and operations, including the supply of the colostrum we purchase to produce our First Defense® product line, the demand for our products in the U.S. market and our ability to penetrate or maintain a profitable presence in international markets. We are experiencing shortages in key components and needed products, backlogs and production slowdowns due to difficulties accessing needed supplies and labor and other restrictions which increase our costs and affect our ability to consistently deliver our products to market in a timely manner. Our exposure to this risk is mitigated to some extent by the fact that our supply chain is not heavily dependent on foreign manufacturers, by our on-going cross-training of our employees, by qualifying alternate suppliers and components and by our early and continued compliance with recommended hygiene. Despite our best efforts and intentions, there is a risk that an employee could become infected and could infect others. Russia’s unprovoked military invasion of Ukraine and attack on its people is having a significant negative impact on the world economy, worsening trends that were already moving in an unfavorable direction. Among other exposures, the increasing price of oil is already impacting our transportation-related expenses materially, and we expect this supply stress to increase the cost of petroleum-based products that we purchase (mostly plastics).
ImmuCell Corporation
Climate change: Our business, and our activities and the activities of our customers and suppliers, could be disrupted by climate change. Potential physical risks from climate change may include altered distribution and intensity of rainfall, prolonged droughts or flooding, increased frequency of wildfires and other natural disasters, rising sea levels, and a rising heat index, any of which could cause negative impacts to our and our customers’ and suppliers’ businesses. Increased temperatures and rising water levels may negatively impact our dairy and beef livestock customers by increasing the prevalence of parasites and diseases that affect food animals. The physical changes caused by climate change may also prompt changes in regulations or consumer preferences which in turn could have negative consequences for our and our customers’ businesses. Climate change may negatively impact our customers’ operations, through climate-related impacts such as increased air and water temperatures, rising water levels and increased incidence of disease in livestock. In addition, concerns regarding greenhouse gas emissions and other potential environmental impacts of livestock production have led to some consumers opting to limit or avoid consuming animal products. If such events affect our customers’ businesses, they may purchase fewer of our products, and our revenues may be negatively impacted. Climate driven changes could have a material adverse impact on the financial performance of our business and on our customers. In addition, increased frequency of natural disasters and adverse weather conditions may disrupt our manufacturing processes or our supply chain. These disruptions may have a material adverse effect on our business, financial condition, results of operations and/or cash flows.
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® product line is manufactured from bovine milk (colostrum), which is not considered a BSE risk material. Future regulatory action to increase protection of the human food supply could affect the First Defense® product line, although presently we do not anticipate that this will be the case.
Risks Pertaining to Common Stock
Stock market valuation and liquidity: Our common stock trades on The Nasdaq Stock Market (Nasdaq: ICCC). Our average daily trading volume (which was approximately 6,612 shares per day during the 20-day period ended March 10, 2023) is lower, our bid/ask stock price spread can be larger and our share price can be more volatile than what other companies experience, which could result in investors facing difficulty selling their stock for proceeds that they may expect or desire. Our share price as of March 10, 2023 was $5.49. Most companies in the animal health sector have market capitalization values that greatly exceed our current market capitalization of approximately $43 million as of March 10, 2023. Our product sales during the year ended December 31, 2022 were approximately $19 million. This means that our market valuation as of March 10, 2023 was equal to approximately 2 times our sales during the year ended December 31, 2022. 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 product under development and may therefore be negatively affected by the related uncertainties and risks.
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 common stock. These provisions may also prevent or frustrate attempts by our stockholders to replace or remove our management. 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, potentially 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 corporation 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.
ImmuCell Corporation
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.
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 facilities and production equipment, and to increase our working capital and to reduce debt. Stockholders must be prepared to rely on market sales of their common stock after price appreciation 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, contractual 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 to access the capital markets again 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.
Other Risks
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, we are experiencing difficulty in efficiently acquiring essential supplies. We have significantly increased the number of farms from which we purchase colostrum for the First Defense® product line. A significant reduction in farm capacity could make it difficult for us to produce enough inventory to meet customer demand. The specific antibodies that we purify from colostrum for the First Defense® product line are not readily available from other sources. We are and will be dependent on our manufacturing facilities and operations in Portland for the production of the First Defense® product line and Re-Tain®. We will be dependent on one manufacturer for the supply of syringes for Re-Tain®. We are currently dependent on a contract with Norbrook for the Drug Product (DP) formulation and aseptic filling of our Nisin DP for orders scheduled for delivery during the second half of 2023. The facility we are constructing to perform these services in-house will be subject to FDA inspection and approval, the outcome and timing of which are not within our control. We expect to achieve FDA approval for use of our DP facility during 2025. The 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). Any significant damage to or other disruption in the services at any of these third-party facilities or our own facilities (including due to regulatory issues or non-compliance) would adversely affect the production of inventory and result in significant added expenses and potential loss of future sales.
Failure to protect intellectual property: The protection and enforcement of our intellectual property rights may require the expenditure of significant financial, managerial and operational resources. We rely on trademark, copyright and patent law, trade secret protection, agreements and other methods with our employees and others to protect our proprietary rights. However, we may be unable to adequately protect our intellectual property rights or prevent third parties from infringing or misappropriating our intellectual property rights. We may not be able to obtain registration for all intellectual property we seek to register, and effective intellectual property protection may not be available in every country in which our products are sold. 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 trade secrets, operational safeguards and contractual agreements. Reliance upon trade secret, rather than patent, protection may cause us to be vulnerable to competitors who successfully replicate (knock off) our manufacturing techniques and processes. Further, our confidentiality agreements may not effectively prevent disclosure of our proprietary information, technologies and processes and may not provide an adequate remedy in the event of unauthorized disclosure of such information. Others may independently develop similar trade secrets or technology or obtain access to our unpatented trade secrets or proprietary technology. Others 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. If that were to be the case, there can be no assurance that we will be able to obtain licenses to such patents on terms that are acceptable to us. Any of our intellectual property rights may be challenged by others or invalidated through administrative process or litigation. Third parties may claim in the future, that we have infringed their intellectual property rights, which could result in significant costs and potential damages and license requirements. We may initiate claims or litigation against others for infringement, misappropriation or violation of our intellectual property rights or other proprietary rights or to establish the validity of such rights. However, we may be unable to discover or determine the extent of any infringement, misappropriation or other violation of our intellectual property rights and other proprietary rights. In addition, we may be unable to prevent third parties from infringing upon, misappropriating or otherwise violating our intellectual property rights and other proprietary rights.
ImmuCell Corporation
Increasing dependence on the continuous and reliable operation of our information technology systems: We rely on information systems throughout our company. Any disruption of these systems or significant security breaches could adversely affect our business. Although we maintain information security policies and employ system backup measures and engage in information system redundancy planning and processes, such policies, measures, planning and processes, as well as our current disaster recovery plan may be ineffective or inadequate to address all eventualities. As information systems and the use of software and related applications by us, our business partners, suppliers, and customers become more cloud-based, we become inherently more susceptible to cyberattacks. There has been an increase in global cybersecurity vulnerabilities and threats, including more sophisticated and targeted cyber-related attacks that pose a risk to the security of our information systems and networks and the confidentiality, availability and integrity of data and information. There are reports of increased activity by hackers and scammers during the COVID-19 pandemic. Russia’s unprovoked military invasion of Ukraine may elevate the risk of such cyberattacks. Any such attack or breach could compromise our networks and the information stored thereon could be accessed, publicly disclosed, lost, or stolen. While we have invested in our data and information technology infrastructure (including working with an information security technology consultant to assess and enhance our security systems and procedures, and periodically training our employees in such systems and procedures), there can be no assurance that these efforts will prevent a system disruption, attack, or security breach and, as such, the risk of system disruptions and security breaches from a cyberattack remains. We have not experienced any material adverse effect on our business or operations as a consequence of any such attack or breach but may incur increasing costs in performing the tasks described above. Given the unpredictability of the timing, nature and scope of such disruptions and the evolving nature of cybersecurity threats, which vary in technique and sources, if we or our business partners or suppliers were to experience a system disruption, attack or security breach that impacts any of our critical functions, or our customers were to experience a system disruption, attack or security breach via any of our connected products and services, we could potentially be subject to production downtimes, operational delays or other detrimental impacts on our operations. Furthermore, any access to, public disclosure of, or other loss of data or information, including any of our (or our customers’ or suppliers’) confidential or proprietary information or personal data or information, as a result of an attack or security breach could result in governmental actions or private claims or proceedings, which could damage our reputation, cause a loss of confidence in our products and services, damage our ability to develop (and protect our rights to) our proprietary technologies and have a material adverse effect on our business, financial condition, results of operations or prospects. While this exposure is common to all companies, larger companies with greater resources may be better able to mitigate this risk than we can.

ITEM 2 - PROPERTIES
Building 56:
During 1993, we purchased a 15,000 square foot facility (that included 5,000 square feet of unfinished office space on the second floor) at 56 Evergreen Drive in Portland, Maine. We currently use this space for substantially all of our: i) office and laboratory needs, ii) vaccine manufacturing operations, iii) liquid processing operations and iv) freeze-drying operations for our USDA-regulated product line. All of our powder milling and filling operations, gel formulation operations and assembly services have been relocated out of this building. During 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. During 2007, we built out the 5,000 square feet of unfinished space on the second floor into usable office space. After moving offices from the first floor 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 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. These additions increased the size of the facility to approximately 34,850 square feet.
Building 33:
During 2015, we exercised an option to acquire land at 33 Caddie Lane in Portland, Maine which is near our facility at 56 Evergreen Drive, on which we initiated construction of our Drug Substance production facility for Re-Tain® 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. Our FDA-regulated operations are conducted in this building.
ImmuCell Corporation
Building 14:
During 2017, we purchased a 4,080 square foot facility adjacent to the Drug Substance production facility for Re-Tain® at 14 Wedge Way in Portland, Maine. We are using this warehouse space primarily for storage of inventory, materials and equipment. We are presently modifying this facility for packing, shipping and cold storage for Re-Tain® and other warehousing needs. We expect these modifications to be complete during the middle of 2023.
Building 175:
During 2019, we entered into a lease covering approximately 14,300 square feet of office and warehouse space to expand our USDA-regulated manufacturing operations. We have renovated this space (a Certificate of Occupancy was issued during the second quarter of 2020) to help us expand our production capacity and improve quality for the First Defense® product line. This space is being used for all of our powder milling and filling, gel formulation and assembly services. The original lease term was ten years with a right to renew for a second ten-year term and a right of first offer to purchase. During the third quarter of 2022, we entered into a new 20-year lease covering a facility that is now being constructed by our landlord (Building 165, described below), which is adjacent to (and could be connected to) Building 175. In connection with this new lease, the lease to Building 175 was extended by approximately 13 years to match the expiration of the other lease to Building 165.
Building 165:
During the third quarter of 2022, we committed to lease an additional 15,400 square feet of space at 165 Industrial Way in Portland, Maine, which could be connected to Building 175, over a 20-year term. The lease commencement date is when the landlord is issued a Certificate of Occupancy for the building shell, which is anticipated to be around the beginning of the second quarter of 2023. Lease payments begin four months after this date. We intend to use this space for the following three purposes: 1) improve product quality by moving powder milling out of Building 56, 2) provide much needed additional warehouse space and 3) provide space for additional freeze-drying equipment to increase our production capacity to approximately $40 million per year. Due to the loss in gross margin on product sales during the first quarter of 2023 caused by the slowdown in production output necessary to remediate a product contamination event, we have decided to defer, for the time being, completion of the investment to build out Building 165. The objective to separate our powder milling operations out of Building 56 has been achieved by moving milling to Building 175 for the time being.
Other:
During the first quarter of 2017, we entered into a renewable, two-year lease for approximately 1,350 square feet of office, warehouse and garage space in Warsaw, New York to support our farm operations. This lease was extended through and terminated at the end of March of 2021. During March of 2021, we entered into a different renewable, two-year lease for approximately 1,300 square feet of office, storage and parking space in New York. Subsequently, we entered into a new two-year lease to the same property through March of 2025 that includes an option to renew for an additional two-year term. We are renting approximately 960 square feet in Winona, Minnesota for a sales office. This lease automatically renews with 4% increases for one-year terms unless we or the landlord give 60-days’ notice of a change. The current term expires in June 2023. We do not expect to provide notice of cancellation at this time. We also maintain access to cows (as a source of colostrum used in the production of the First Defense® product line) through contractual relationships with commercial dairy farms. We maintain property insurance in amounts that approximate replacement cost and a modest amount of business interruption insurance.

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 audited 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, 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 some of the important factors that could cause actual results to differ materially from the results, objectives or expectations described in or implied by the forward-looking statements contained in the following discussion and analysis.
Liquidity and Capital Resources
Net cash (used for) operating activities was ($1.5) million during the year ended December 31, 2022 in contrast to net cash provided by operating activities of $954,000 during the year ended December 31, 2021. The $2.5 million decrease in net cash provided by operating activities from period to period was largely the net result of a $2.4 million increase in the net loss with $2 million more cash being used to build inventory being net against $1.8 million more cash being generated by the collection of accounts receivable. As we increased our production capacity to eliminate the backlog of orders, our inventory balance increased to $6 million as of December 31, 2022 from $3.1 million as of December 31, 2021. Our total depreciation and amortization expense was approximately $2.5 million during both of the years ended December 31, 2022 and 2021. We anticipate that depreciation expense, while not affecting our cash flows from operations, will be a significant factor in creating annual net operating losses until and unless product sales increase sufficiently to offset these non-cash expenses. Net cash (used for) investing activities was ($4) million during the year ended December 31, 2022 in comparison to net cash (used for) investing activities of ($1.6) million during the year ended December 31, 2021. Approximately $4 million and $2.6 million of cash was used to acquire property, plant and equipment during the years ended December 31, 2022 and 2021, respectively, which payments were largely related to our ongoing investments to expand our manufacturing facilities. Net cash provided by financing activities decreased to $1.1 million during the year ended December 31, 2022 in comparison to net cash provided by financing activities of $3.9 million during the year ended December 31, 2021. During 2022, we received $2 million in debt proceeds compared to $400,000 in debt proceeds received during 2021. We raised no new equity during 2022, but during 2021, we raised $4.2 million from a public offering of common stock. Debt principal repayments will continue to reduce our cash flows.
ImmuCell Corporation
We entered into several bank debt refinancings and amendments with Gorham Savings Bank (GSB) from the first quarter of 2020 to the first quarter of 2022 that have improved our liquidity by spreading our principal payments out over a longer period of time and pushing out balloon principal payment obligations that existed under some of the repaid debt. Also, because all of this debt bears interest at fixed rates, we are avoiding the adverse effects of rising interest rates on our debt service costs. The blended interest rate on this debt, including the State of Maine debt from the Maine Technology Institute (MTI) described below, is 3.65% per annum (3.52% per annum excluding the MTI debt). As of December 31, 2022, we had total bank debt outstanding (including the MTI debt) of approximately $10.2 million as compared to approximately $9.1 million as of December 31, 2021. Debt principal repayments aggregated approximately $897,000 and $768,000 during the years ended December 31, 2022 and 2021, respectively. We anticipate that debt principal repayments will aggregate approximately $1 million during the year ending December 31, 2023. Interest expense (excluding amortization of debt issuance costs) was approximately $341,000 and $307,000 during the years ended December 31, 2022 and 2021, respectively. We anticipate that interest expense will be approximately $352,000 during the year ending December 31, 2023. During the first quarter of 2022, the availability of our $1.0 million line of credit, which bears interest at the National Prime Rate per annum, was extended until March 11, 2024. These credit facilities are secured by substantially all of our assets, including our facility at 56 Evergreen Drive in Portland (which was independently appraised at $6.3 million in connection with the 2022 financing) and our facility at 33 Caddie Lane in Portland (which was independently appraised at $3.2 million in connection with a 2017 financing and at $2.5 million in connection with a 2020 refinancing). These credit facilities are subject to certain restrictions and financial covenants. We are required to meet a minimum debt service coverage (DSC) ratio set by GSB of 1.35. Our actual DSC ratio was equal to 2.68, 2.03 and 1.57 during the years ended December 31, 2021, 2020 and 2019, respectively. By negotiation with GSB in connection with the 2022 financing, the required minimum DSC ratio was reduced to 1.0 for the year ending December 31, 2022. The actual DSC ratio during the year ended December 31, 2022 was 0.44. The compliance requirement with the DSC ratio was waived by GSB for 2022. During the first quarter of 2023, the DSC ratio covenant for the year ending December 31, 2023 was waived by GSB. Instead, we are required to meet a minimum DSC ratio requirement of 1.35 for the twelve-month periods ending June 30, 2024, September 30, 2024 and December 31, 2024 and then again annually after that.
During June 2020, we received a $500,000 loan from the Maine Technology Institute (MTI). The first 2.25 years of this loan were interest-free with no interest accrual or required principal payments. Principal and interest payments at a fixed rate of 5% per annum are due quarterly over the final 5 years of the loan, which began during the fourth quarter of 2022 and continues through the third quarter of 2027. During July 2021, we received an additional $400,000 loan from the MTI. The first 2 years of this second loan are interest-free with no interest accrual or required principal payments. Principal and interest payments at a fixed rate of 5% per annum are due quarterly over the final 5.5 years of the loan, beginning during the third quarter of 2023 and continuing through the fourth quarter of 2028. Both loans are unsecured and subordinated to all other bank debt from GSB and may be prepaid without penalty at any time. This support from the State of Maine through the MTI helps us move forward aggressively with our investments while increasing our total employee count.
From the first quarter of 2016 through the second quarter of 2021, we raised gross proceeds of approximately $26.7 million (net proceeds were approximately $24.8 million) from six different common equity transactions priced between $5.25 and $8.25 per share with a weighted average price of approximately $5.87 per share. No warrants were issued in connection with any of these transactions, and no convertible or preferred securities were issued. This capital, together with our bank debt and gross margin from product sales, has allowed us to transform the Company. We are (and have been) investing significantly to increase our capacity to produce the First Defense® product line from approximately $16.5 million to approximately $40 million in annual sales volume per year. The actual value of our production capacity varies based on biological and process yields, product format mix, selling price and other factors. Based on our best estimates and projections, we believe that our cash and cash equivalents, together with gross margin anticipated to be earned from ongoing product sales, will be sufficient to meet our currently planned working capital and capital expenditure requirements and to finance our ongoing business operations for at least 12 months (which is the period of time required to be addressed for such purposes by accounting disclosure standards) from the date of this filing. The table below summarizes the changes in selected, key accounts (in thousands, except for percentages):

We have invested and continue to invest in eight different capital expenditure projects to increase our production capacity for the First Defense® product line and complete the development of Re-Tain®. When we describe the production capacity for the First Defense® product line in this report, it should be noted that the actual value of this capacity varies based on biological and process yields, product format mix, selling price and other factors. From 2014 to 2019, we initiated four capital expenditure investments, as described in the following table (in thousands):

Total Project Cost $ 4,205 $ 21,640 $ 3,653 $ 4,000 $ 33,498
PROJECT A included a 7,100 square foot facility addition at 56 Evergreen Drive and related equipment (including freeze-dryer #2) and cold storage capacity to increase the production capacity for the First Defense® product line. During the first quarter of 2016, we completed this investment, increasing our freeze-drying capacity by 100% and making other improvements to our liquid processing capacity, which increased our annual production capacity (in terms of annual sales dollars) to approximately $16.5 million. This investment also included the construction and equipping of a pilot plant for small-scale Drug Substance production for Re-Tain® within our First Defense® production facility at 56 Evergreen Drive. After PROJECT B was completed, this space was converted for use in the production of the gel tube formats of the First Defense® product line at 56 Evergreen Drive. After PROJECT C was completed, this space was converted to double our liquid processing capacity at 56 Evergreen Drive.
PROJECT B was related to the Drug Substance production facility for Re-Tain® at 33 Caddie Lane. During the fourth quarter of 2017, we completed construction of the Drug Substance production facility. We began equipment installation during the third quarter of 2017, and we completed this installation during the third quarter of 2018. The total cost of this investment for the Drug Substance production facility and related processing equipment was $20.8 million plus $331,000 for the land and $472,000 for the acquisition of an adjacent 4,080 square foot warehouse facility at 14 Wedge Way, which will be used for packing, shipping and cold storage of Re-Tain® and other warehousing needs. (See PROJECT G, below).
PROJECT C consisted of significant renovations to a 14,300 square foot leased facility at 175 Industrial Way, some facility modifications at 56 Evergreen Drive and the necessary production equipment (including freeze-dryer #3) to increase the annual production capacity of the First Defense® product line (in terms of annual sales dollars) from approximately $16.5 million to approximately $23 million. This expansion involved a 50% increase in our freeze-drying equipment and a 100% increase in our liquid processing capacity. Renovations to our leased facility at 175 Industrial Way to enable this expansion were completed during the second quarter of 2020. By moving our powder and gel filling and assembly services from 56 Evergreen Drive into this new space at 175 Industrial Way, we created space at 56 Evergreen Drive for the installation of the expanded freeze-drying capacity. The new facilities are built to contemporary cGMP standards with good material and people flows. A site license approval for this new facility at 175 Industrial Way was issued by the USDA during the third quarter of 2020. During the second quarter of 2021, we completed the relocation of our gel formulation equipment from 56 Evergreen Drive to 175 Industrial Way, which created the space necessary to double our liquid processing capacity at 56 Evergreen Drive. We obtained site license approval of the expanded freeze-drying capacity at 56 Evergreen Drive from the USDA during the third quarter of 2021, and we obtained site license approval of the expanded liquid processing capacity at 56 Evergreen Drive from the USDA during the third quarter of 2022. As part of this investment, we also made the facility modifications at 56 Evergreen Drive to create the space necessary to expand our freeze-drying equipment (including freeze-dryer #4) by an additional 33%, which would increase our annual production capacity from approximately $23 million to approximately $30 million or more (together with the work involved in PROJECT F discussed below).
ImmuCell Corporation
PROJECT D is a $4 million budgeted investment to bring the formulation and aseptic filling capabilities for Re-Tain® Drug Product into available space in our Drug Substance facility to end our reliance on third-party Drug Product manufacturing services. We began initial equipment installation during the first quarter of 2022. We have presently paused this installation work pending concurrence with the FDA pertaining to our third submission of the CMC Technical Section, which is discussed in greater detail below. Due to the loss in gross margin during the first quarter of 2023 caused by the slowdown in production output necessary to remediate a product contamination event, we have decided to defer spending of approximately 42% of these funds for the time being. We anticipate FDA approval of this facility (which is a requirement for commercial manufacturing) during 2025 if we resume spending on this project in the coming months.
During 2021, we initiated three more capital expenditure investments, and during the second quarter of 2022, we initiated one additional capital expenditure investment, as described in the following table (in thousands):

Total Paid through December 31, 2022 2,186 3,841
Estimate to Complete - 4,367 5,340
Total Project Cost $ 750 $ 957 $ 3,074 $ 4,400 $ 9,181
PROJECT E represents a $750,000 budget for equipment and vehicle investments necessary to expand and improve our colostrum collection capabilities and logistics. We largely completed this investment during 2022 but have left the project open as we are considering the need to purchase an additional farm truck.
PROJECT F included installation of freeze-dryer #4 for $957,000 to further increase the annual production capacity of the First Defense® product line (in terms of annual sales dollars) from approximately $23 million to approximately $30 million or more. We initiated PROJECT F during the third quarter of 2021. Due to supply disruptions affecting key components and equipment, this investment was not completed until the end of 2022.
PROJECT G represents an increased budget estimate of $3,000,000 (from the previous budget estimate of $2,840,000). Of this total, approximately $2,325,000 is for equipment and facility modifications to scale-up and upgrade our vaccine manufacturing capacity, improve our quality laboratories and install new equipment for our gel filling operations and approximately $675,000 is to build packing and shipping facilities for Re-Tain® at 14 Wedge Way. This investment includes automation of our gel filling operations as part of our strategy to increase our annual production capacity for the First Defense® product line (in terms of annual sales dollars) to approximately $30 million. This investment is running approximately $74,000 over its increased budget amount of $3,000,000.
PROJECT H represents a new investment in building modifications and equipment to further increase our annual First Defense® production capacity from approximately $30 million to approximately $40 million with options for further expansion. Given the long lead time required for investments like this, during 2022 we initiated this project by entering into a lease during the third quarter of 2022 covering a to-be-constructed 15,400 square foot building shell at 165 Industrial Way for approximately $250,000 per year, which operating cost is not included in the capital expenditure table above. We anticipate a lease commencement date (after the landlord completes construction of the building shell) during the second quarter of 2023. We made this lease commitment because of the unique proximity of the land adjacent to our currently leased space at 175 Industrial Way and the high level of demand for properties of this type in the Portland market. We did not want to risk losing this opportunity to others. The anticipated benefits to us from this new lease include: i) space for the potential to install freeze-dryers #5, #6, #7 and #8 if justified by market demand in the future, ii) improved space and quality for our powder milling operations by separating our upstream processes (liquid processing) at 56 Evergreen Drive from our clean downstream processes (milling, formulation, filling and packaging) and iii) much needed additional warehouse space. Freeze-dryer #5 is the key piece of equipment required to allow us to increase our annual production capacity to approximately $40 million. Based on past experience, we are planning for approximately 18 to 24 months of lead time for fabrication, installation, qualification and implementation of freeze-dryer #5. We have been running our equipment and staff near to 100% of capacity over the last couple of years in order to fill the backlog of orders. One of the objectives of PROJECT H is to create a more sustainable production schedule. Due to the loss in gross margin during the first quarter of 2023 caused by the slowdown in production output necessary to remediate a product contamination event, we have decided to defer, for the time being, approximately 95% of this investment.
ImmuCell Corporation
We have been investing (and continue to invest) significantly in equipment, infrastructure and operating expenses to increase our annual production capacity from approximately $16.5 million to approximately $30 million. Increased labor and other upfront costs were necessary to benefit from the scale-up of our production output going forward. These investments have been (and are being) made to fulfill the current backlog and then materially reduce the risk of another order backlog. We have been operating at very close to 100% of available capacity recently, which is not efficient or sustainable. Going forward, we will be in a position to operate at the capacity level we choose to cover sales with adequate buffer stock. This allows more time for necessary preventative maintenance and redundancy for when equipment failures occur. At the same time, we have been investing (and continue to invest) in capital expenditures necessary to manufacture Re-Tain® at commercial scale and to cease our reliance on aseptic filling contractor services. The table below summarizes the investment made and to be made under PROJECT A to PROJECT H by product (in thousands):

Re-Tain® 23,989 2,326 26,315
Total $ 35,652 $ 7,027 $ 42,679
(1) The investment of approximately $4,200,000 of these funds has been deferred for the time being.
In addition to the specific projects listed above, our budget for routine and miscellaneous capital expenditures for the year ended December 31, 2022 was $825,000. We spent approximately $34,000 more than this budget amount during 2022, and we expect to spend approximately $97,000 during 2023 to complete these miscellaneous expenditures from the 2022 budget. These routine and miscellaneous capital expenditures amounted to $260,000, $554,000 and $574,000 during the years ended December 31, 2021, 2020 and 2019, respectively. The spend on this budget category during 2021 was lower than expected, and, as a result, the spend during 2022 was higher than the historical norm. The budget for these miscellaneous capital expenditures during 2023 is $1,000,000. Due to the loss in gross margin during the first quarter of 2023 caused by the slowdown in production output necessary to remediate a product contamination event, we have decided to reduce spending on these routine and miscellaneous capital expenditures by 50% for the time being.
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 for Re-Tain® by 65% over the eleven-year period beginning on July 1, 2017 and ending June 30, 2028 and by 30% during the year 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. The value of the tax savings will increase (decrease) in proportion to any increases (decreases) in the assessment of the building for city real estate tax purposes or the City’s tax rate. The following table discloses how much of the new taxes we have generated is being relieved by the TIF and how much is being paid by ImmuCell:

Results of Operations
Business Segments
As detailed in Note 17, “Segment Information”, to the accompanying audited financial statements, we operate in two business segments. The Scours segment is dedicated to manufacturing and selling First Defense®, a product used to prevent scours in newborn calves, which is regulated by the USDA. The Mastitis segment is focused on developing and commercializing Re-Tain®, a product to treat subclinical mastitis in lactating dairy cows, which is regulated by the FDA.
ImmuCell Corporation
Product Sales
Through continued growth in sales of the First Defense® product line, and as additional resources are dedicated to production, sales, marketing and technical services, it is our objective to exceed our total product sales of approximately $19 million achieved during the year ended December 31, 2022 as soon as possible. Our longer-term goal is to exceed $35 million of annual total product sales as soon as possible during the five-year period after the market launch of Re-Tain®. We do not solely benchmark our sales expectations off trailing twelve-month sales results. Instead, we look at the sales of competitive products to assess the size of the addressable market and plan for growth when projecting our future production capacity needs.
Sales decreased by 4%, or $675,000, to $18.6 million during the year ended December 31, 2022, in comparison to $19.2 million during the year ended December 31, 2021. Domestic sales during the year ended December 31, 2022 increased by 2%, and international sales decreased by 41%, in comparison to the year ended December 31, 2021. International sales aggregated 8% and 14% of total sales during the years ended December 31, 2022 and 2021, respectively. The annual sales results are summarized in the following table (in thousands, except for percentages):
During the Years Ended
December 31, (Decrease)
Amount %
Total product sales $ 18,568 $ 19,243 $ (675 ) (4 )%
Sales of the First Defense® product line aggregated 99% and 98% of our total sales during the years ended December 31, 2022 and 2021, respectively. Our sales are seasonal with highest sales expected during the first quarter of each year. Most of our growth (when not limited by backlog) is being realized through increased demand and a deliberate strategy to prioritize production capacity towards Tri-Shield First Defense® (the trivalent format of our product delivered via a gel tube), which provides broader protection to calves. The compound annual growth rate (CAGR) of our total product sales was 12.4%, 14.0% and 10.6% during the eleven-year, four-year, and three-year periods ended December 31, 2022, respectively.
Valuation of the backlog is a non-GAAP estimate that is based on purchase orders on hand at the time that could not be met because of a lack of available inventory. Quantification of the backlog during the current periods has become far less comparable to prior periods. At times, customers have placed orders for more than a month’s worth of their demand, perhaps in reaction to our ongoing backlog situation, whereas in the past they ordered more closely in line with their current demand. The backlog was reduced from approximately $2.4 million as of December 31, 2021 to approximately $205,000 as of September 30, 2022. We had adequate finished goods inventory to ship most of this backlog during the third quarter, but the product was held for cold shipping on the first Monday of October. In part because of a first contamination event experienced around the end of the third quarter of 2022, our backlog increased to approximately $2.5 million as of December 31, 2022. In part because of a second contamination event experienced during the first quarter of 2023, the backlog increased further to approximately $8 million as of March 10, 2023. We are reporting this figure because it does reflect the orders on our books presently that we cannot ship. However, we do not believe this backlog is highly relevant anymore as it includes very old orders, redundancy in demand and orders that may be cancelled. We likely lost some business during 2022 as a result of the backlog. Our inability to timely meet the needs of our customers could result in the loss of some customers who seek alternative scours management products during this period of short supply and who may not resume purchasing our product when we have eliminated the backlog. While we worked to allocate product directly to certain large customers during this period of short supply, we likely lost some customers that could not access product. While backlog is a better problem to have than seeing product expiring on our shelves, it is nonetheless a significant challenge when we do not get our customers everything that they want. Our sales team is preparing to resume more normal sales growth initiatives with more inventory becoming available later in 2023. We will work to regain customers that we may have lost while we were short on product and will aggressively compete for new business. As we emerge from an extended period of time on backlog, we anticipate higher than normal sales fluctuations quarter to quarter. What is most important to us at this time is that we achieve sales growth over the longer periods of time, even if we experience some quarter-to-quarter fluctuations.
A supply disruption pertaining to needed plastic syringes used in our gel product format resulted in the drop in sales during the second quarter of 2022. This supply disruption was resolved during the third quarter of 2022. The significant global supply-chain disruptions that almost all industries are experiencing presently are a challenge to us and contribute to our order backlog. Prices for raw materials and critical supplies are increasing significantly, and it is becoming increasingly more difficult to obtain timely delivery of the orders that we place. Therefore, we have little choice but to pay the higher prices and try to take on more months of supply than we would have held previously if we could get our orders fulfilled timely.
Effective January 1, 2023, we increased our selling price of the First Defense® product line by approximately 3% (range of 2% to 4%) and CMT by approximately 5%. Effective January 1, 2022, we increased our selling price of the First Defense® product line by approximately 5% and CMT by approximately 7%. Effective January 1, 2021, we increased our selling price of the First Defense® product line in the domestic market by approximately 1.6% to 3%, depending on product format, and we increased our selling price of CMT by almost 4%.
ImmuCell Corporation
We acquired a private label product (our second leading source of product sales during 2021) in connection with our January 2016 acquisition of certain gel formulation technology. This product was discontinued during the first quarter of 2022 because it was not a significant contributor to our total sales and it competed for valuable time and space in our production schedule. We sell our own CMT (our third leading source of product sales during 2021), which is used to detect somatic cell counts in milk. Sales of these products (other than the First Defense® product line) decreased by approximately 50%, or $154,000, to $156,000 during the year ended December 31, 2022, in comparison to the year ended December 31, 2021. Sales of these other products aggregated approximately 1% and 2% of our total product sales during the years ended December 31, 2022 and 2021, respectively.
Gross Margin
The change in our gross margin (product sales less costs of goods sold) and our gross margin as a percentage of product sales are summarized in the following table (in thousands, except for percentages):
During the Years Ended
December 31, (Decrease)
Amount %
Gross margin $ 7,649 $ 8,656 $ (1,007 ) (12 )%
Percent of product sales 41 % 45 % (4 )% (8 )%
The gross margin as a percentage of product sales was 41%, 45%, 45%, 49%, 47% and 50% during the years ended December 31, 2022, 2021, 2020, 2019, 2018 and 2017, respectively. The gross margin during the year ended December 31, 2022 was significantly less than what we have experienced historically and significantly less than what we anticipate going forward. We experienced several product contamination events that resulted in scrap during 2022. This resulted in a total charge to costs of goods sold of approximately $588,000. Although these types of losses are expected to happen from time to time in the production of a biological product such as ours, we believe we can mitigate the risk of reoccurrence of such losses through the implementation of certain processes and facility improvements. Absent this contamination write-off, our gross margin as a percentage of product sales would have been approximately 44% during the year ended December 31, 2022. While our biological and process yields can be variable, we have seen a favorable improvement to our finished goods yield recently. The costs of our supplies, components, raw materials, and services increased significantly during 2021 and that trend has continued. The Tri-Shield® product format is more complex (i.e., three antibodies versus two antibodies for Dual-Force®) making it more costly to produce, and both the bivalent and trivalent gel product formats are more expensive to produce than the bolus format. These new formats are creating sales growth for us, and we are focused on increasing total gross margin dollars, even if that is accomplished with a lower gross margin as a percentage of sales. A number of other factors contribute to the variability in our costs, resulting in some fluctuations in gross margin percentages from quarter to quarter and from year to year. Like most U.S. manufacturers, we have also been experiencing increases in the cost of labor and raw materials. We also invest to sustain compliance with current Good Manufacturing Practices (cGMP) in our production processes. Increasing production can be more expensive in the initial stages. To achieve our inventory production growth objectives, we are acquiring more raw material (colostrum) from many more cows at many new farms. During this expansion phase, colostrum quality can be more variable. Additionally, the biological yields from our raw material are always variable, which impacts our costs of goods sold in a similar way. 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 vaccines. As is the case with any vaccine program, animals respond less effectively to their first exposure to a new vaccine, and thereafter the effectiveness of their immune response improves in response to subsequent immunizations. While this variability impacts our costs of producing inventory, the commercial value of our First Defense® product line is that we compensate for the variability in a cow’s immune response by standardizing each dose of finished product. This ensures that every calf is equally protected, which is something that dam-level commercial scours vaccines cannot offer. We continue to work on processing and yield improvements and other opportunities to reduce costs, while enhancing process knowledge and robustness. Over time, we have been able to reduce the impact of cost increases by implementing yield improvements. We believe that gross margin results should be viewed over longer periods of time than just one quarter. As we fully integrate and utilize our increased capacity and evaluate our product costs and selling price, one of our goals is to achieve a gross margin (before related depreciation and amortization expenses) as a percentage of total sales approaching 50%.
Product Development Expenses and Strategy
Overview: The majority of our product development expenses pertain to the development of Re-Tain®. During the year ended December 31, 2022, product development expenses increased by approximately $325,000 to approximately $4.5 million in comparison to the approximately $4.2 million during year ended December 31, 2021. Product development expenses aggregated 24% and 22% of product sales during the years ended December 31, 2022 and 2021, respectively. Product development expenses included approximately $1.4 million and $1.5 million of non-cash depreciation and stock-based compensation expenses during the years ended December 31, 2022 and 2021, respectively. We expect our product development expenses to decrease after Re-Tain® is commercialized and some of the costs incurred to maintain and run our Drug Substance production facility become part of our costs of goods sold.
ImmuCell Corporation
Development objective: As we work to revolutionize the way that mastitis is managed in the dairy industry, we aim to demonstrate that our bacteriocin, Nisin A, which is designed specifically for subclinical mastitis, can provide producers the freedom to change when and how mastitis is treated. Re-Tain® is not a broad-spectrum antibiotic used in human health. Rather, it consists of a highly targeted active ingredient without a milk discard or meat withhold requirement. While milk prices vary, the cost of the milk discard associated with traditional antibiotics ranges from approximately $46.12 (for 3.5 days of milk at 60 pounds per day at the Class III milk price average of $21.96 per hundredweight during 2022) to $193.25 (for 11 days of milk at 80 pounds per day at the Class III milk price average of $21.96 per hundredweight during 2022) per treated animal. These high milk discard costs associated with traditional antibiotic treatments lead producers to only treat mastitis after clinical signs develop. We expect that Re-Tain® will be a first-of-its-kind product that can be used to economically treat at the earliest stage of infection, giving producers the ability to get ahead of mastitis before clinical signs develop so the best cows stay at their best performance level and in the herd longer. The final and most critical development objective for Re-Tain® is to scale-up and achieve regulatory approval of our manufacturing operations.
Development status: Approval by the Center for Veterinary Medicine, U.S. Food and Drug Administration (FDA) of the New Animal Drug Application (NADA) for Re-Tain® is required before any sales of the product can be initiated. The NADA is comprised of five principal Technical Sections plus a sixty-day administrative review at the end. Each Technical Section can be reviewed and approved separately. By statute, each Technical Section submission is generally subject to one or more six-month review cycles by the FDA. 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. During the second quarter of 2021, we received further clarification through a new Environmental Impact Technical Section Complete Letter covering the current dosage regimen and labeling.
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 anticipated product label (which remains subject to FDA approval) carries claims for the treatment of subclinical mastitis associated with Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis, and coagulase-negative staphylococci in lactating dairy cattle.
4) Human Food Safety: 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. Achieving this critical differentiating feature for our product encouraged us to continue the significant product development investment necessary to bring Re-Tain® to market. It would have been hard to justify an ongoing investment of this nature in a product without this significant competitive advantage. During the second quarter of 2021, we updated this Technical Section Complete Letter with FDA approval of the official analytical method to measure Nisin in milk.
5) Chemistry, Manufacturing and Controls (CMC): The CMC Technical Section is very complex and comprehensive. Having previously achieved the four different Technical Section Complete Letters from the FDA discussed above, approval of the CMC Technical Section is the fifth and final significant step required before Re-Tain® product sales can be initiated in the United States. Implementing Nisin Drug Substance (the active pharmaceutical ingredient, or DS) production, which is a required component of the CMC Technical Section, has been the most expensive and lengthy part of this project. We previously entered into an agreement with a multi-national pharmaceutical ingredient manufacturer for our commercial-scale supplies of DS. However, we determined during 2014 that the agreement did not offer us the most advantageous supply arrangement in terms of either cost or long-term dependability. As a result, 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, we concluded that a partner would have taken an unduly large share of the gross margin from all future product sales of Re-Tain®. However, the regulatory and marketing feedback 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 produce our DS at small-scale at our 56 Evergreen Drive facility. 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 DS production facility. Having raised equity during 2016 and 2017, we were able to move away from these earlier partnering strategies and assume control over the commercial-scale manufacturing process in our own facility. During the fourth quarter of 2015, we acquired land near our existing Portland facility for the construction of a new commercial-scale DS production 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. Total construction and equipment costs aggregated approximately $20.8 million. With construction of the facility complete, we continue to work with outside parties to investigate improvements to our DS production yields as well as potential efficacy enhancements.

Under the FDA’s phased submission process, we made a first-phased submission covering just the DS during the first quarter of 2019. The first-phased DS submission included data from the DS Registration Batches produced at commercial scale in our new DS manufacturing facility. This first-phased submission was followed by a second-phased submission covering both the DS and the formulated Drug Product (DP), during the first quarter of 2021. This two-phased submission process allowed us to respond to identified queries and/or deficiencies from the first-phased DS submission at the time of the second-phased combined DS and DP submission. The second-phased DS and DP submission responded to comments raised by the FDA regarding the first-phased DS submission and included detailed information about the manufacturing process and controls for DP. One of the key components of the second-phased DS and DP submission was also demonstrating stability of the product through expiry. During the third quarter of 2021, the FDA issued a Technical Section Incomplete Letter with regard to this second-phased DS and DP submission. This response was not unexpected as it is common for the FDA to issue queries and comments, especially related to an aseptic DP submission with associated sterilization validation information. We made a second submission of the DS and DP Technical Section during the first quarter of 2022. During the third quarter of 2022, we received a Technical Section Incomplete Letter from the FDA with regards to this second DS and DP submission of the CMC Technical Section. We have been working diligently to make this third submission during the first quarter of 2023. As previously disclosed, the submission requires that external laboratories complete several critical path items regarding our analytical testing. While we have made significant progress in addressing these issues, we are still reliant on the work of others to finalize the submission. To that end, we are adding another month to our timeline to complete the analysis and, in our view, optimize the submission rather than forcing the submission to achieve a self-imposed first quarter deadline. We intend to make a brief public disclosure after this submission has been made. The principal issue remaining is a successful pre-approval re-inspection of our manufacturing facility. We are completing preparations for such and intend to notify the FDA of our readiness for the pre-approval re-inspection as part of our third submission. Continued focus on these preparations is critical to a successful pre-approval re-inspection outcome. We expect a response from the FDA to this submission after the statutory six-month review period. If the FDA issues a Technical Section Complete Letter in response to this third submission, we believe that we could commence commercial sales around the end of 2023.
While being prudent with how much cash we invest into inventory that would have short expiry dating if market launch is delayed, we have built and are building more DS inventory during 2022 and 2023 to bridge the transition between DP supply from our contract manufacturer to our own in-house services. Our contract manufacturer has agreed to convert this DS to DP during the middle of 2023 with associated product expirations during the middle of 2025. This inventory must support the market needs and have sufficient dating to bridge the transition from our contract manufacturing agreement to when our in-house DP production is approved by the FDA. We must consider short expiry dating in the event that our NADA approval is delayed as well as manage the number of new customers we obtain at launch in order to minimize potential supply disruptions.
Our DS manufacturing facility and that of our DP contract manufacturer (and our future DP manufacturing facility) are subject to ongoing FDA inspections. During the third quarter of 2019, the FDA conducted a pre-approval inspection of our DS facility. This resulted in the issuance of certain deficiencies as identified on the FDA’s Form 483. We submitted responses and data summaries in a phased manner over the fourth quarter of 2019 and first quarter of 2020. During the first quarter of 2022, the FDA conducted another pre-approval inspection of our DS facility. This also resulted in the issuance of certain deficiencies as identified on the FDA’s Form 483. We have since responded to all of the queries and are preparing for a re-inspection, which will likely take place during the six-month review period for our third submission of the CMC Technical Section. This inspection process has been managed without significant cost.
We have always believed that the fastest route to FDA approval and market launch is with the services of Norbrook Laboratories Limited of Newry, Northern Ireland (an FDA-approved DP manufacturer) (Norbrook), reducing our risk by benefiting from their demonstrated expertise in aseptic filling. From 2010 to the present, we have worked with Norbrook under several amended contract manufacturing agreements covering the DP formulation, aseptic filling and final packaging services. Under our current agreement, Norbrook has agreed to provide the formulation, aseptic filling and final packaging services as required in order for us to submit the CMC Technical Section to the FDA and to provide a supply of product during the second half of 2023 that we believe will enable us to commence sales of Re-Tain® without delay upon receipt of the anticipated FDA approval and provide us with a supply bridge until our own formulation and aseptic filling capacity is available, which is anticipated during 2025 (see discussion of PROJECT D above). DP produced under this agreement during the second half of 2023 is expected to have expiry dating during the second half of 2025.
ImmuCell Corporation
Our potential alternative third-party options for the formulation and aseptic filling services that are presently being performed by Norbrook are narrowed considerably because our product cannot be formulated or filled in a facility that also processes traditional antibiotics (i.e., beta lactams). Consequently, we have decided to perform these services internally (see discussion of PROJECT D above). We are investing in the equipping and commencement of operations of our own DP formulation and aseptic filling facility. We began initial equipment installation during the first quarter of 2022. Subject to the timing of our installation and validation work, we anticipate FDA approval of this facility (which is a requirement for commercial manufacturing) during 2025, allowing for two six-month review cycles. This new facility will be subject to FDA inspection and approval and will have enough formulation and aseptic filling capacity to exceed the expected production capacity of our DS facility, which is at least $10 million in annual sales. This production capacity estimate is based on our assumptions as to product pricing and does not yet reflect inventory build strategies in advance of product approval or ongoing yield improvement initiatives. Establishing our own DP formulation and aseptic filling capability provides us with the longer-term advantage of controlling the manufacturing process for Re-Tain® in one facility, thereby potentially reducing our manufacturing costs and eliminating international cold chain shipping logistics and costs. The DP formulation and aseptic filling operation will be located in existing facility space that we had intended to utilize to double our DS production capacity if warranted by sales volumes following market launch. As a result, we would need to explore alternative strategies (in parallel with ongoing DS yield improvement initiatives) to expand our DS production capacity. This integrated manufacturing capability for Re-Tain® will substantially reduce our dependence on third parties. Upon completion of our formulation and aseptic filling facility, the only significant third-party input for Re-Tain® will be the DP syringes. It is anticipated that Hubert De Backer of Belgium (HDB) will supply these syringes in accordance with purchase orders that we submit. HDB is a syringe supplier for many of the largest participants in the human and veterinary medical industries, and with whom Norbrook presently works. Based on HDB’s performance history and reputation in the industry, we are confident that HDB will be a dependable supplier of syringes in the quantity and of the quality needed for Re-Tain®.
Other product development initiatives: Our second most important product development initiative has been focused on other improvements, extensions or additions to our First Defense® product line. We are currently working to establish USDA claims for our bivalent bulk powder formulation of First Defense Technology®. 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, subject to the availability of the needed funding.
Sales and Marketing Expenses and Selling Strategy
During the year ended December 31, 2022, sales and marketing expenses increased by approximately 27%, or $686,000, to $3.2 million in comparison to $2.5 million during the year ended December 31, 2021, amounting to 17% and 13% of product sales during the years ended December 31, 2022 and 2021, respectively. Sales and marketing expenses included approximately $158,000 and $70,000 of non-cash depreciation and stock-based compensation expenses during the years ended December 31, 2022 and 2021, respectively. Our budgetary guideline for 2023 and after is to keep these expenses under 20% of total sales. We continue to leverage the efforts of our small sales force by using animal health distributors.
We see ourselves as the “non-pharma” pharma company. Rather than offering variations of “copy-cat” technology like vaccines and antibiotics, we have taken the path less traveled by developing first-of-their kind products fueled by novel active ingredients such as polyclonal antibodies (for First Defense®) and bacteriocins (for Re-Tain®). While we expect that Re-Tain® could be a significant market disrupter, we project the First Defense® market could be larger, especially during the first years of the commercial launch of Re-Tain®. We anticipate that these category developing innovations will drive greater value for the livestock industry and, in turn, for our stockholders.
The First Defense® product line serves dairy and beef producers by protecting their calf crop from scours, the leading cause of pre-weaning mortality and morbidity. When calves are healthy during this crucial development period, they mature into more productive milking cows and more efficient beef generators. Our primary competition in this category is vaccines that are also regulated for effectiveness and safety by the USDA. However, vaccine results are inherently variable. COVID breakthrough infections in humans have reminded us that a vaccine does not guarantee immunity. That is true for our competitors as well. In the most controlled research settings, only 80% of animals respond to a vaccine. This leaves 20% of the calf crop unprotected when the scour prevention program relies on scour vaccines. Those unprotected calves can be disease carriers. Not only are they more susceptible to death or likely to require life-saving treatment (sometimes with antibiotics), but they also shed pathogens into the environment creating a greater disease pressure for their herd mates. The First Defense® product line removes the inconsistency inherent with vaccine protection. We sell the only USDA-licensed products in the scour prevention category that are therapeutic polyclonal antibodies. This technology eliminates a producer’s reliance on a variable vaccine response to generate antibodies and, instead, can protect every calf equally with a measured dose of antibody-driven immunity against both bacterial and viral scour pathogens.
In this space, we treat more calves than our competitors where products are primarily vaccines administered directly to the calf at birth, and we are second in sales dollars to the market leader within the dam-level competitor category, which constitutes vaccines given to the cow pre-calving. Despite these successes, there remains significant opportunity to displace more competition within North America. There is also opportunity to grow our sales by expanding into international markets. We are being strategic in how we invest in international market development in order not to divert our limited resources away from achieving domestic growth, which is often more efficient to obtain.
ImmuCell Corporation
Our expanded sales and marketing team has proven to be a worthy investment, validating that our message resonates well with customers. Now that our increased production capacity is in place, we anticipate being able to escalate our growth curve after we recover from the brand damage that can come with an extended duration of short supply. Unfortunately, just after we largely eliminated the backlog of orders, we experienced several contamination events in our production process around the end of the third quarter of 2022. This loss of inventory has returned us to a backlog situation until we fill the pipeline with new inventory from our expanded production capacity in 2023.
We believe that Re-Tain® could revolutionize the way that mastitis is managed by making earlier treatment of subclinical infections (while these cows are still producing saleable milk) economically feasible by not requiring a milk discard or a meat withhold during, or for a period of time after, treatment. No other FDA-approved mastitis treatment product on the market can offer this value proposition. We believe we can demonstrate 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, which are all sold subject to milk discard and meat withhold requirements. By creating this value for our customers, we believe we can, in turn, create value for our stockholders.
Re-Tain® could increase the lifetime profitability of a cow and reduce disease transfer to herd mates. 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. While practices may vary farm-to-farm, there would be no requirement to move cows treated with our product, allowing this costly drop in production to be avoided. 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, leaving most subclinically infected cows untreated. Without a milk discard cost, we expect producers to be more motivated to identify and treat cows at the subclinical stage. This creates a substantial animal welfare benefit. By treating mastitis early at the subclinical level, producers could preserve optimal milk yields. We also know that animals infected with subclinical mastitis have higher abortion rates and often progress to the clinical disease state requiring antibiotic treatment and milk discard. We believe that societal animal welfare objectives will put more and more pressure on the industry to treat cows with subclinical infections.
The over-use of antibiotics that are medically important to human healthcare is a growing public health concern of our society and an active issue with the FDA, largely because of the growing evidence that this over-use contributes to antibiotic resistance and the rise of “super-bugs”. Sustainability objectives require that less antibiotics be used in food producing animals, yet a new FDA-approved drug to treat mastitis has not been developed in years. Our product improves sustainability by utilizing a bacteriocin as an alternative to traditional antibiotics that are used in human medicine. In the big picture, we are introducing an entirely new class of antimicrobial as an animal drug, a bacteriocin, that does not promote resistance against antibiotics used in human medicine making it more socially responsible. The industry could keep treating this very significant disease with traditional antibiotics, but it takes innovation to bring a bacteriocin like Nisin to market. Re-Tain® would, when introduced, offer a needed alternative to these traditional antibiotics, while at the same time improving milk quality and the quantity of milk produced by treated cows. We believe our product fits very well with where the industry is going to be in the coming years. As the great NHL hockey player, Wayne Gretzky, is known to have said, “I skate to where the puck is going to be, not where it has been.” This is motivational to us.
As with all new products, the market determines the value. Our objective is to gain market acceptance of this new product concept as we develop a new product category. Despite our product’s exciting benefits, it will take time to change this longstanding treatment paradigm and develop this new market. It will take time for the market to understand, evaluate, implement and adapt to the use and benefits of Re-Tain®. Based on consultations with industry experts and key opinion leaders, we have opted to carefully control the launch of this novel product over the first eighteen to twenty-four months after FDA approval, as we seek to transform the way that mastitis is treated in the dairy industry over the long term. Our goal is to help early adopters select treatment candidates, develop easy to use protocols, optimize treatment results and realize a positive return on their investment. We intend to limit initial distribution of Re-Tain® to a level that enables our sales team to select the optimal dairy farms at which to introduce Re-Tain® and to limit the initial numbers of participating farms so that the desired levels of support and guidance relating to effective usage of Re-Tain® can be provided with our available resources. Our overarching objective is to minimize the risk of early stage unsatisfactory outcomes that could harm the longer term prospects and market acceptance of Re-Tain®. This strategy also reduces the amount of inventory that we would need to build at risk before regulatory approval is achieved, and it reduces the amount of cash we would need to spend to purchase inventory from our contract manufacturer before our in-house aseptic filling services are approved by the FDA. This strategic choice means that we have elected not to pursue an alternative strategy that might have maximized short-term, initial sales quickly through a mass market approach where we provide product to distribution and let them sell it to as many farms as possible. While we are dedicated to increasing our sales revenue, we must consider the damage a mass market strategy could cause to the long-term value of the product. We have seen products sold by much larger companies that were substantially damaged by such failed market launch strategies. We continue to develop detailed launch plans, focusing on the readiness of dairy operators to successfully introduce Re-Tain® to their herds. We believe that these prudent steps, while potentially leading to lower initial Re-Tain® revenues, may create a smooth and successful launch and could safeguard the longer term performance of our investment in Re-Tain®. We also believe that the operational adjustments and accommodations that dairy farmers will need to make to effectively use Re-Tain® and avoid the potential problems described under PART I: ITEM 1A - RISK FACTORS, “Product Risks”, to this Annual Report will not be so burdensome as to deter its adoption and usage. Our overarching objective is to minimize the risk of early-stage unsatisfactory outcomes that could harm the longer-term prospects and market acceptance of Re-Tain®.

It is difficult to accurately estimate the potential size of the subclinical mastitis market because presently this disease is largely left untreated. We believe that approximately 20% to 40% of the U.S. dairy herd is infected with subclinical mastitis at any given time. 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. Rarely is an industry revolutionized overnight. Getting producers to change protocols to make subclinical mastitis treatment a standard and routine procedure is going to take initiative, but we believe producers are eager for something new and better since the FDA has not approved an intramammary treatment within the last 20 years. Similar market opportunities are likely to exist outside the United States. We believe the use of Re-Tain® could be expanded, with additional data and regulatory approval, to support treatment late in lactation and possibly for clinical stage mastitis. We also believe there may be a market for Re-Tain® in small ruminants, where the majority of mastitis cases are caused by strep-like organisms aligned with our effectiveness data.
We expect the Drug Substance production facility that we constructed for approximately $20.8 million to have initial annual production capacity sufficient to meet at least $10 million in sales of Re-Tain® at current production yields. This production capacity estimate does not yet reflect any inventory build strategies or ongoing yield improvement initiatives. Expansion of the estimated annual capacity of the Drug Substance facility beyond approximately $10 million (without factoring in potential yield improvements) would require relocation of the Drug Product formulation and aseptic filling module to another facility, or the acquisition and equipping of other Drug Substance production facilities or adopting alternative manufacturing strategies.
In an effort to provide greater visibility into the launch of Re-Tain®, we have expanded Note 17, “Segment Information”, to the accompanying audited financial statements to now display a break-out of our financial results among the following three components of our business: i) Scours, ii) Mastitis and iii) Other. This will allow investors to see our progress with both products. We generally do not provide financial projections, as we know such projections can prove to be materially inaccurate. However, in this case, we are providing a high-level projection for Re-Tain® that under our controlled launch plan strategy, we estimate that we can achieve sales of approximately $1 million in 2024 and then achieve approximately twice that in 2025. This assumes FDA approval is achieved and that product launch is initiated around the end of 2023. If we are successful with this launch strategy, we would aim to grow this curve in 2026 and after. We believe this strategy lends itself to a more gradual adoption curve but higher and more sustainable sales over the long-term. Actual sales results will vary from these projections up or down.
Administrative Expenses
During the year ended December 31, 2022, administrative expenses increased by 31%, or approximately $538,000, to $2.3 million in comparison to $1.7 million during the year ended December 31, 2021. The increase in administrative expenses during the year ended December 31, 2022 compared to the year ended December 31, 2021 was largely the result of the accrual of approximately $222,000 in deferred compensation expense (consisting of earned and unused paid time off) during the first quarter of 2022. Administrative expenses included approximately $148,000 and $122,000 of non-cash depreciation and stock-based compensation expenses during the years ended December 31, 2022 and 2021, 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. Given the growth in our business, our administrative staff has increased to four talented individuals reporting to our CEO. 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. Given travel restrictions related to the COVID-19 pandemic, this initiative has pivoted to a virtual meeting format, which is less expensive. Having experienced this efficiency, it is our intent to continue with the same strategy, for the most part, even as travel restrictions continue to be reduced. At the same time, we continue 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. We believe these efforts have helped us access the capital markets to fund our growth objectives. Considering inflation and all the necessary support services that fit into this category, we believe that approximately $2 million to $2.5 million per year is an efficient budget goal to fund the administrative expenses of a publicly-held company.
Net Operating (Loss) Income
During the year ended December 31, 2022, our net operating (loss) of ($2.3) million was in contrast to net operating income of $257,000 during the year ended December 31, 2021. The $1.5 million increase in operating expenses and the $1 million decrease in gross margin made up most of the $2.6 million increase in the net operating loss.
Other Expenses, net
During the year ended December 31, 2022 other expenses, net, aggregated $187,000 in comparison to other expenses, net, of $327,000 during the year ended December 31, 2021. Interest expense increased to $349,000 during the year ended December 31, 2022 from $314,000 during the year ended December 31, 2021. Non-cash amortization of debt issuance costs (which is included as a component of interest expense) was $8,000 during both of the years ended December 31, 2022 and 2021. We anticipate that our interest expense will be approximately $352,000, $323,000 and $279,000 during the years ending December 31, 2023, 2024 and 2025, respectively. Interest income was $153,000 and $19,000 during the years ended December 31, 2022 and 2021, respectively. More interest income was earned during 2022 largely because of a higher interest rate environment. The (gain) loss on disposal of property, plant and equipment was approximately ($7,000) and $31,000 during the years ended December 31, 2022 and 2021, respectively.
ImmuCell Corporation
Loss Before Income Taxes
During the year ended December 31, 2022, our loss before income taxes was $2.5 million in comparison to a loss before income taxes of $69,000 during the year ended December 31, 2021.
Income Taxes and Net Loss
During the years ended December 31, 2022 and 2021, we recorded income tax expense of $8,000 and $9,000, respectively, which is comprised of minimum state tax liabilities. Our net loss of $2.5 million, or $0.32 per basic share, during the year ended December 31, 2022 was in comparison to a net loss of $78,000, or $0.01 per basic share, during the year ended December 31, 2021.
We have substantial net operating loss carryforwards that largely offset our income tax expense. For tax return purposes only, our depreciation expense for the Nisin Drug Substance production facility and equipment was approximately $425,000, $492,000, $464,000, $639,000, $9.2 million and $1.5 million for the years ended December 31, 2022, 2021, 2020, 2019, 2018 and 2017, respectively. The significant increase during 2018 was largely related to accelerated depreciation allowed for tax purposes. As of December 31, 2022, our federal net operating loss carryforward was approximately $15.5 million, which will be available to offset future taxable income, subject to possible annual limitations based on ownership changes. 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 34% to 21%. Our income tax rate differs from this statutory tax rate primarily because we are currently providing for a full valuation allowance against our deferred tax assets. While we are recording this full valuation allowance, we are not recognizing the benefit of our tax losses.
In addition to the results discussed above from our Statements of Operations, we believe it is important to consider our Statements of Cash Flows in the accompanying audited financial statements to assess the cash generating ability of our operations.
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, 2022 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 the following: 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 distributors) 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 business, less reasonably predictable costs of completion, disposal and transportation). Work-in-process and finished goods inventories include materials, labor and manufacturing overhead. The assumptions used by management to determine the cost of inventory and costs of goods sold involve a significant level of estimation and uncertainties that could have a material impact on our financial condition and results of operations largely because of the variability of the costs per dose due to fluctuations in the biological yield from production batch to batch.

ITEM 9A. CONTROLS AND PROCEDURES
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, 2022. 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. 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 annual or quarterly 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.
Material Weakness in Internal Controls over Financial Reporting: Management assesses the effectiveness of the Company’s internal control over financial reporting at the end of each quarter. Based on this assessment, we concluded that our internal control over financial reporting was not effective as of September 30, 2022, June 30, 2022 and March 31, 2022, because we identified one material weakness in the operation (but not the design) of our internal controls over financial reporting during the first quarter of 2022 and a second one during the third quarter of 2022. First, we did not accrue $222,000 of deferred compensation expense (consisting of earned and unused paid time off) during the first quarter of 2022, which impacted the amount of our administrative expenses, accrued expenses and the related disclosures. Second, we did not properly account for the extension of our lease agreement at 175 Industrial Way, which would have understated the value of our operating lease right-of-use asset and operating lease liability by approximately $1,200,000 if the error had not been detected before we issued our Quarterly Report on Form 10-Q for the three-month and nine-month periods ended September 30, 2022. These errors had no impact on our product sales or cash position. We do believe that the design of our internal controls is effective, but the operating effectiveness was not. We have implemented some changes to our internal controls over financial reporting, including documenting the accounting for all contractual obligations in excess of $50,000 with accounting complexities in written memorandums to be reviewed by a public accounting firm who is not our auditor or by another relevant consultant when the issues are complex in nature. As a result, we have concluded that these material weaknesses over internal controls have been remediated as of December 31, 2022. Based on management’s assessment, we believe that our internal controls over financial reporting were effective as of December 31, 2022.
Changes in Internal Controls over Financial Reporting: Our principal executive and principal financial officer and our Director of Finance and Administration periodically evaluate any change in internal control over financial reporting which has occurred during the prior fiscal quarter. We have concluded that, with the exception of the enhanced internal control procedures discussed in the prior paragraph, there was no change in our internal control over financial reporting that occurred during the three-month period or year ended December 31, 2022 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
