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.

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, protein-rich food 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.

During 2000, we began the development of Re-Tain ® ,

the way that farmers treat mastitis, the single most significant cause of economic loss to the dairy industry.

Full commercial sales

of this product cannot be made without prior approval of our New Animal Drug Application (NADA) by the Center for Veterinary Medicine,

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 have made our third submission

of the fifth Technical Section.

We expect a response to this third submission from the FDA by May of 2024.

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.

During the eight-year period beginning January 1,

2016 and ended December 31, 2023, we funded our operations, constructed an FDA-regulated Drug Substance (DS) manufacturing facility for

Re-Tain ® and invested capital to increase our production capacity for the First Defense ® product

We have also initiated another capital investment (which investment is currently paused) to bring the formulation and aseptic filling

capabilities for Re-Tain ® in house in order to end our present reliance on an outside contractor.

We have achieved FDA approval for four out of five of the significant Technical Sections required

for product approval.

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

ITEM 7 – MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS ,

for more detail about our investments to increase production capacity.

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

Scrapped product from contamination events (largely this one around the end of the third quarter) and other production process

losses resulted in a total charge to costs of goods sold of approximately $589,000 during 2022.

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.

We slowed down our production output to take the

necessary steps to assess and remediate the issues and perform a deep sanitization of our facilities and process equipment.

After several

months of processing without further contamination, we experienced a third contamination event during the third quarter of 2023.

product from contamination events and other production process losses resulted in a total charge to costs of goods sold of approximately

$527,000 during 2023.

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 worked 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, while

continuing to ensure that any product that is put to market meets all quality standards.

We believe that our efforts to increase production

capacity for the First Defense ® product line are linked to our product contaminations.

It was relatively simple

to run at lower production capacities for the 30 years between 1991 (the original USDA approval of First Defense ® )

The contamination events we suffered during 2022 and 2023 were largely the result of us processing more milk (colostrum) than

ever before in order to meet increasing customer demand.

As we enter 2024, we believe that we have much improved processes and controls

in place to better support large-scale production from our raw material source farms through liquid processing.

Our most important customer-focused

objectives going forward are to fulfill the large backlog of orders and then again be a reliable supplier of a very effective product

to the dairy and beef calf market.

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.

was relatively simple to run at lower production capacities for the 30 years between 1991 (the original USDA approval of First Defense ® )

We believe that the contamination events we suffered between 2022 and 2024 stemmed from us processing more milk (colostrum)

from more farms than ever before in order to increase production output and meet increasing customer demand.

We believe that we now have

significantly improved processes and controls in place to better support large-scale production from our raw material source farms through

liquid processing.

Our most important customer-focused objectives going forward are to fulfill the backlog of orders and then resume

being a reliable supplier of a very effective product to the dairy and beef calf markets.

Once achieved, our goal is to continue to expand

our penetration of the beef market and less price sensitive dairies with Tri-Shield ® , while simultaneously launching

a lower-cost spray-dried product without USDA claims, targeting more price sensitive large calf ranches and dairies.

Overall, our goal

is to continue to grow sales and differentiate our brands in both the beef and dairy markets.

line to provide Immediate Immunity™ generates a dependable and competitive return on investment for dairy and beef producers.

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 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.

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.

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.

However, heat stress on calves caused by extremely hot summer weather can increase the incidence of scours, just as harsher winter

Nisin treatment for subclinical mastitis in lactating cows.

During the 24-year period that began on January 1, 2000 and ended on December

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 ® .

was earned from 2001 to 2007.

More recently, we have initiated a preliminary investigation into potential applications

of Nisin for human healthcare, but we do not see a clear commercial path at this time.

2004, we entered into a product development and marketing agreement with Zoetis (formerly Pfizer Animal Health, a division of Pfizer,

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

The impact of this potential interference ranges from a delay in the manufacturing process (which does happen at times for other

reasons) to the less likely stopping of a cheese starter culture.

Milk from cows that have been treated with our product that is sold

exclusively for fluid milk products presents no such risk.

We worked with scientists and mastitis experts to conduct a formal risk assessment

to quantify the impact that milk from treated cows may have on cultured dairy products.

This study concluded that the dilution of milk

from treated cows through comingling with milk from untreated cows during normal milk hauling and storage practices reduces the risk of

interference with commercial dairy cultures to a negligible level when the product is used in accordance with the product label.

we 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.

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.

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 ® .

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.

Our Nisin technology

includes patented processing and purification methods to achieve pharmaceutical-grade 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

We are also investigating potential applications of Nisin for other animal health applications as well as for humans.

initiative (in terms of dollars invested and, we believe, potential market impact) has 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 ® .

beef industries when we have adequate cash reserves.

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.

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

Second, being derived from colostrum, our product offers Immediate Immunity TM 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 (Calf-Guard ® )

that competes directly with the First Defense ® product line in preventing scours via oral delivery to newborn calves.

We anticipate initiating commercial sales of a new spray-dried

quarts of high quality colostrum immediately after birth when dosing a calf with our product, which is standard practice for good calf

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.

When compared to the other USDA-approved calf-level

scours preventatives, we lead in both sales dollars and calves treated within the U.S.

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.

to treat mastitis, such as Boehringer Ingelheim, Merck Animal Health and Zoetis, to be among the potential competitors with respect to
