PART I.



|ITEM 1. | BUSINESS
|------- | --------

Neogen Corporation and
subsidiaries (Neogen or the Company) develop, manufacture, and market a diverse line of products dedicated to food and animal safety. The Companys food safety segment consists primarily of diagnostic test kits and complementary products (e.g.,
dehydrated culture media) marketed by company sales personnel in North America, the United Kingdom and other parts of Europe, Mexico and Brazil, and by distributors elsewhere to food producers and processors to detect dangerous and/or unintended
substances in human food and animal feed, such as foodborne pathogens, spoilage organisms, natural toxins, food allergens, genetic modifications, ruminant by-products, drug residues, pesticide residues and general sanitation concerns. The diagnostic
test kits are generally less expensive, easier to use and provide greater accuracy and speed than conventional diagnostic methods. The majority of the tests are disposable, single-use, immunoassay and gene probe products that rely on the
Companys proprietary antibodies and RNA and DNA probes to produce rapid and accurate test results. The Companys expanding line of food safety products also includes bioluminescence-based diagnostic technology.

Neogens animal safety segment is engaged in the development, manufacture and marketing of pharmaceuticals, rodenticides, disinfectants, vaccines,
veterinary instruments, topicals and diagnostic products and genetic testing services for the worldwide animal safety market. The majority of these consumable products are marketed through a network of national and international distributors, as
well as a number of large farm supply retail chains in the United States and Canada. The Companys USDA-licensed facility in Lansing, MI, produces immunostimulant products for horses and dogs, and a unique equine botulism vaccine. The
Companys line of drug detection products are sold worldwide for the detection of abused and therapeutic drugs in animals and animal products.

Managements vision is for Neogen to become a world leader in development and marketing of products dedicated to food and animal safety. To meet this vision, a growth strategy consisting of the
following elements has been developed: (i) increasing sales of existing products; (ii) introducing new products and product lines; (iii) expanding international sales; and (iv) acquiring businesses and forming strategic
alliances. While the elements of the strategy are stated in order of importance over the long term, management believes that strategic acquisitions may provide the best opportunity for more rapid growth in the short term. For that reason, an active
acquisition program is maintained and financial and other resources are maintained to capitalize on opportunities as they arise.

Neogen
Corporation was formed as a Michigan corporation in June 1981 and actual operations began in 1982. The Companys principal executive offices are located at 620 Lesher Place, Lansing, Michigan 48912-1595 and its telephone number is
(517) 372-9200.

Neogens Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and amendments to
those reports are available free of charge via our Internet website (www.neogen.com) as soon as reasonably practicable after such information is filed with, or furnished to, the United States Securities and Exchange Commission.

Neogen operates in two primary business areas: the Food Safety segment, which develops and markets products
for the detection of pathogens, natural toxins and other unwanted substances in food and feed products; and the Animal Safety segment, which develops and markets products and services dedicated to animal health. See Notes to Consolidated Financial
Statements elsewhere in this Form 10-K for financial information about the Companys business segments and international operations.

FOOD SAFETY SEGMENT

The products of
Neogens food safety segment consist of diagnostic test kits and complementary products marketed to food and feed producers and processors to detect dangerous and/or unintended substances in food and animal feed, such as foodborne pathogens,
spoilage organisms, natural toxins, food allergens, genetic modifications, ruminant by-products, drug residues, pesticide residues and general sanitation concerns.

Many of Neogens food safety test kits use immunoassay technology to rapidly detect target substances. The Companys ability to produce superior antibodies has set its products apart from
immunoassay test kits produced and sold by other companies. The Companys kits are available in microwell formats, which allow for the rapid processing of a large number of samples and automated procedures, and lateral flow and other similar
devices that provide distinct visual results. Typically test kits use antibody-coated test devices and chemical reagents to produce a color change to indicate a positive or negative result for the presence of a target substance in a test sample. The
simplicity of the tests makes them accessible to all levels of food producers, processors and handlers.

The Companys kits are generally
based on internally developed technology or technology that is acquired in connection with acquisitions. In 2011, Food Safety incurred royalty expense totaling $1,050,000 for licenses and royalties for technology used in the Companys products,
including expense of $410,000 for licenses related to the dairy antibiotics product line and $329,000 for allergen products. All royalty rates are in the low single digit range. Some licenses involve technology that is exclusive to Neogens use
while others are nonexclusive and involve technology licensed to multiple licensees.

Neogens test kits are used to detect potential
hazards in food and animal feed by testers ranging from small local grain elevators to the largest, best-known food and feed processors in the world, and numerous regulatory agencies.

Meat and poultry processors, seafood processors, fruit and vegetable producers and many other market segments are the primary users
of the Neogens Reveal® and Alert® tests for foodborne bacteria, including E. coli O157:H7, Salmonella, ListeriaandCampylobacter. Grain producers and processors of all
types and sizes use the Companys Veratox®, Agri-Screen® and Reveal® tests for
mycotoxins, including aflatoxin, deoxynivalenol, fumonisin, ochratoxin, zearalenone and T-2 toxin, to help ensure product safety and quality. The worlds largest producers of cookies, crackers, candy, ice cream, and many other foods, use the
Companys Veratox®, Alert® and Reveal®, Reveal 3-D and
BioKits testing products for food allergens to help protect their food-allergenic customers from the inadvertent contamination of products with food allergens, such as peanut, milk, casein, egg, almond, wheat (gluten), soy, and hazelnut residues.
The Companys December 2009 acquisition of the BioKits food safety business of Gen-Probe Incorporated added more than 50 test kits for food allergens, meat and fish speciation, and plant genetics, including tests in an advanced lateral flow
format for gluten and casein.

Dairies are primary users of Neogens BetaStar®, BetaStar Combo, Penzyme® and TetraStar® diagnostic
tests to detect the presence of beta lactam and tetracycline antibiotics in milk. The presence of these drugs in milk is a public health hazard, and an economic risk to processors as it limits the milks further processing.

Neogen developed the first rapid immunoassay test kits to detect ruminant by-products in animal feed ingredients and finished feed.
The Reveal® tests were designed to help prevent ruminants (cattle, sheep and goats) from being fed rendered
materials containing ruminant by-products in an effort to prevent the spread of BSE (a.k.a., mad cow disease) from animal to animal. The Companys specialty products for the seafood market include tests for histamine, a highly
allergenic substance that occurs when certain species of fish begin to decay; chloramphenicol, a banned antibiotic in most of the world, but still used by some shrimp farmers to improve the yield of their product; and sulfites, an effective but
potentially allergenic shrimp preservative.

Neogen also offers other test methods and products to complement its
immunoassay tests. The Companys line of GENE-TRAK® and GeneQuence® assays utilize DNA probe hybridization technology to create exceptionally sensitive and specific tests to detect
foodborne bacteria. Instead of using antibodies as in an immunoassay to capture a target pathogen that may be present in a sample, this technology uses a portion of the target pathogens unique ribosomal RNA (rRNA) sequence to bind
to complementary rRNA strands of the pathogen in a sample. The result is a test with the ease and speed of a rapid test method, but the specificity of a time-consuming conventional laboratory method (specificity is a tests ability to
distinguish between a target pathogen, and a closely-related but innocuous bacterium).

Neogens Soleris® product is used by food processors to identify the presence of spoilage organisms (e.g., yeast and mold) and other
microbiological contamination.

Neogens Acumedia® subsidiary offers dehydrated culture media for varied purposes, including traditional bacterial testing, and growing beneficial bacteria, such as cultures for
sausages and beer. The Companys customers for dehydrated culture media also include commercial and research laboratories and producers of pharmaceuticals, cosmetics and veterinary vaccines.

Neogen manufactures and markets its AccuPoint® rapid sanitation test for adenosine triphosphate (ATP), a chemical found in all living cells. This easy-to-use and inexpensive test uses bioluminescence to quickly
(in less than 30 seconds) determine if a food contact surface has been completely sanitized. When ATP comes into contact with the firefly reagent luciferin luciferase contained in the test device, a reaction takes place that produces light. More
light is indicative of higher levels of ATP and a need for more thorough sanitation. The Companys worldwide customer base for its ATP sanitation testing products includes food and beverage processors, the foodservice industry, as well as many
other users.

Revenues from Neogens Food Safety Division accounted for 49.5%, 54.4% and 51.4% of the Companys total revenues for
fiscal years ended May 31, 2011, 2010 and 2009, respectively.

ANIMAL SAFETY SEGMENT

Neogens animal safety segment is engaged in the development, manufacture and marketing of pharmaceuticals, rodenticides, disinfectants, vaccines,
veterinary instruments, topicals and diagnostic products to the worldwide animal safety market. Beginning with the acquisition of GeneSeek, Inc. in 2010, the Company provides important genotyping services to animal breeders throughout the world.

Animal Safetys NeogenVet product line provides innovative, value-added, high quality products to the veterinary market. Top
NeogenVet products include PanaKare, a digestive aid that serves as a replacement therapy where digestion of protein, carbohydrate and fat is inadequate due to exocrine pancreatic insufficiency; Natural Vitamin E-AD, which aids in the
prevention and treatment of vitamin deficiencies in swine, cattle and sheep; and RenaKare, a supplement for potassium deficiency in cats and dogs. Other products sold under the NeogenVet brand include Vita-15 and Liver 7, which are
used in the treatment and prevention of nutritional deficiencies in horses.

In 2003, Neogen acquired Hacco, Inc., a
manufacturer of rodenticides, including the brand Ramik®. On the same date, it also acquired Hess &
Clark, Inc. Hess & Clarks principal products are disinfectants, such as DC&R®, used in animal
and food production facilities.

In early fiscal 2009, Neogen acquired a product line of 14 different product formulations used in animal
health and hygiene applications from DuPont Animal Health Solutions (DAHS). These products, including 904 Disinfectant, Acid-A-Foam, and FarmFluid S added to the Companys strategy of providing biosecurity solutions in the farm
production markets. The products also have the potential for use in the veterinary clinic market to maintain sanitary conditions and limit the potential hazards of bacteria, fungi, and viruses.

Neogens in-house equine protozoal myeloencephalitis (EPM) testing service offers veterinarians accurate, timely results for
early diagnosis of the disease that can devastate a horses central nervous system. In addition, the Companys
BotVax® B vaccine has successfully protected thousands of high-value horses and foals against type B botulism,
commonly known as Shaker Foal Syndrome. The Companys product is the only USDA-approved vaccine for the prevention of Type B botulism in horses.

Years of research and many thousands of doses have proven Neogens
EqStim® immunostimulant to be safe and effective as a veterinarian-administered adjunct to conventional
treatment of equine bacterial and viral respiratory infections. The Companys ImmunoRegulin® product uses
similar immunostimulant technology to aid in the treatment of pyoderma (a bacterial skin inflammation) in dogs.

Neogen markets a broad line
of veterinary instruments and animal health delivery systems under the Ideal product brand name. Approximately 250 different products are offered, many of which are used to deliver animal health products, such as antibiotics and vaccines.
Ideals D3 Needles and the HDN, HDDI and DTN needle product lines that were acquired in the Rivard acquisition are stronger than conventional veterinary needles, and are uniquely detectable by common meat processing facility metal
detectorsa big market advantage in the safety-conscious beef and swine industries.

Animal safety products offered
by Neogen to the retail over-the-counter market include many of the Ideal brand veterinary instruments and products sold under the Squire® and Gold Nugget® brands.
Squire products include Stress-Dex® oral electrolyte replacer for performance horses, and Furazone®, for the prevention and treatment of surface bacterial infections in wounds, burns and cutaneous ulcers. Gold Nugget
OTC products include GNatural Spray, to protect horses from biting insects, and Poridon®, a pour-on
insecticide for horses. Ag-Tek® and other hoof care, disposables and artificial insemination supplies that were
acquired in the Kane acquisition are marketed to the dairy and veterinary industries.

Neogens line of approximately 100 drug detection immunoassay test kits are sold worldwide for the
detection of approximately 300 abused and therapeutic drugs in farm animals and racing animals, such as horses, greyhounds and camels, and for detection of drug residues in meat and meat products. The test kits are also used for human forensic
toxicology drug screening applications. This line includes tests for narcotics, analgesics, stimulants, depressants, tranquilizers, anesthetics, steroids and diuretics.

In April 2010, Neogen acquired GeneSeek, Inc., a leading commercial agricultural genetics testing laboratory in the United States. Geneseek was founded in 1998 and employed 36 people as of the acquisition
date. GeneSeeks technology employs high-resolution DNA genotyping for identity and trait analysis in a variety of important animal and agricultural plant species. Through the use of single nucleotide polymorphism (SNP) discovery and analysis,
GeneSeek empowers its customers to speed genetic improvement efforts, as well as identify economically important diseases.

Neogen also has several products used by researchers for the detection of biologically-active substances. These products include
tests for cyclic nucleotides, hormones, leukotrienes, prostaglandins and steroids. Marketed under the trademarks of
K-Blue® and K-Gold®, Neogen offers proprietary substrates that it uses in its own testing products, and that are sold to other diagnostic test kit manufacturers.

Revenues from Neogens Animal Safety Division accounted for 50.5%, 45.6% and 48.6% of the Companys total revenues for fiscal years ended
May 31, 2011, 2010 and 2009, respectively.

GENERAL SALES AND MARKETING

Neogens sales efforts are generally organized by specific markets, rather than by products or geography. During the fiscal year that ended May 31, 2011, the Company had approximately 6,000
customers for its products. Since many customers for animal safety products are distributors, and certain animal safety products are offered to the general retail market, the total number of end users of the Companys products is considerably
greater than 6,000. As of May 31, 2011 a total of 187 employees were assigned to sales and marketing functions within the Company. During the year ended May 31, 2011, no single customer or distributor accounted for 10% or more of the
companys revenues. In the year ended May 31, 2010, revenues from one food safety distributor customer were 10.3% of total revenues. No other customer represented in excess of 10% of consolidated revenues.

DOMESTIC SALES AND MARKETING

FOOD
SAFETY

To reach each customer and prospect with expertise and experience, Neogen has a staff of specialized food safety sales and technical
service representatives assigned to specific markets. This staff sells Company products directly to end users, and also handles technical support issues that arise with customers.

Neogens food safety markets are comprised of: milling and grain, including grain elevators, feed mills, pet food manufacturers, and grain inspection companies; meat and poultry, including meat and
poultry processors, producers of ready-to-eat meat and poultry products; and the USDAs Food Safety Inspection Service (FSIS); grocery products, including flour millers, malters, bakeries, candy and confection manufacturers, manufacturers of

ANIMAL SAFETY

Neogen markets a broad range of pharmaceuticals, vitamin injectibles, wound care
products, topicals, instruments, testing services and biologicals to the ethical veterinary market. The product range is focused on the food (cattle and pigs) and companion (horses, dogs,

and cats) animal markets. Neogens sales group works directly with veterinarians, clinics and universities and markets through established ethical distributors by supporting the efforts of over 500
domestic distributor sales representatives calling on 35,000 plus veterinarians. Neogen further supports its veterinary distribution channel through product training, field support, promotions and technical service.

The over-the-counter (OTC) animal health market is expected to continue to offer significant growth opportunities for Neogen and its products. Neogen
offers a broad range of products including well recognized brands of rodenticides, disinfectants, instruments and horse care products. To reach the OTC market, Neogens sales team works with a large network of animal health distributors
including marketing groups, traditional two-step distributors, catalogers and large retail chains. Support includes product training, field support, planogram solutions, promotions and advertising. As a commercial laboratory, GeneSeek provides
services direct to large-herd beef and dairy cattle, swine, poultry and sheep producers.

FOOD SAFETY:

Neogen Europe, Ltd. provides the Company access to the European Union, and allows it
to serve its network of customers and distributors throughout the EU. Customers in the United Kingdom, France and Germany are served by Company employees. Other European region customers generally are serviced by distributors managed by Neogen
Europe personnel. Neogen Europes strong research and development continue to be a strong asset in the development of products tailored to meet unique requirements of the European market.

In 2008, Neogen formed a subsidiary in Mexico, Neogen Latinoamérica. The company, headquartered in Mexico City, distributes the
Companys food and animal safety products throughout Mexico. Neogen Latinoamérica unifies Neogens widespread business activities throughout the region to animal and crop producers, and food processors.

In October 2009, Neogen formed a subsidiary in Brazil, Neogen do Brasil (Neogen of Brazil). The new company, headquartered near Sao Paulo, distributes
Neogens food and animal safety products throughout Brazil. Neogen do Brasil was created to accelerate the success of Neogen products in Brazil, which has become one of the worlds largest food producers and exporters. Brazil is the world
leader in the export of numerous food commodities, including beef, poultry, soybeans, coffee, sugar, and orange juice.

Internationally,
outside of the company locations mentioned above, Neogen uses its own sales managers to work closely with and coordinate the efforts of a network of approximately 120 distributors in more than 100 countries. The distributors provide local training
and technical support, perform market research, and promote Company products within designated countries around the world.

Neogens
dairy antibiotics diagnostic products are distributed outside of North America, Brazil and China by Denmark based Chr. Hansen, an international supplier of natural ingredient solutions for the food and health and nutritional industries.

Neogens Soleris diagnostic test system for general spoilage organisms is marketed worldwide by Neogen personnel and the Companys network of
distributors.

Since 2002, Neogen has maintained a presence in Shanghai, China, to better serve the expanding food safety market there, as
well as more closely manage its Chinese food and animal product procurement. Neogen intends to continue to use local distributors to introduce the Companys products in the Chinese market.

ANIMAL SAFETY:

The Animal Safetys
international sales group has established a strong presence in several key markets with rodenticides, disinfectants, instruments, diagnostics and veterinary products. Utilizing company personnel in Brazil and Mexico, as well as in-country
distributors and US-based exporters, these markets include Canada, Mexico and Central America, Brazil and South America, the Caribbean, Australia, Europe and Asia.

GENERAL:

International sales accounted for 42.1%, 39.9% and 41.0% of the Companys total
revenues for fiscal years ended May 31, 2011, 2010 and 2009, respectively.

Risks associated with foreign operations include the need for
regulatory approvals, possible disruptions of product delivery, the differing product needs of foreign customers, difficulties in building and managing foreign operations, fluctuations in the value of foreign currencies, import/export duties and
quotas, and unexpected regulatory, economic or political changes in foreign markets.

RESEARCH AND DEVELOPMENT

Management maintains a strong commitment to Neogens research and development activities. The Companys product development efforts are focused
on the enhancement of existing product lines and in development of new products that fit its business strategy. As of May 31, 2011, the Company employed 54 individuals in its research and development department, including immunologists,
chemists, engineers and microbiologists. Research and development expenditures were approximately $6.8 million, $6.3 million and $4.6 million representing 4.0%, 4.5% and 3.8% of total revenues in fiscal 2011, 2010 and 2009, respectively. Management
currently intends to maintain the Companys research and development expenditures at approximately 4% to 6% of total revenues.

Neogen has ongoing development projects for new diagnostic tests and other complementary products for both
the food safety and animal safety markets. Management expects that these products will be available for marketing in fiscal years 2012 to 2014. Expenditures in FY-2012 are expected to be approximately 4% of total revenues.

Portions of certain technologies utilized in some products marketed by Neogen were acquired from or developed in collaboration with affiliated
partnerships, independent scientists, governmental units, universities and other third parties. The Company has entered into agreements with these parties that provide for the payment of license fees and royalties based upon sales of products that
utilize the pertinent technology. License fee and royalties expensed under these agreements amounted to $1,561,000, $1,337,000 and $1,184,000 in 2011, 2010 and 2009, respectively.

PROPRIETARY PROTECTION AND APPROVALS

Neogen uses trade secrets as proprietary protection
in numerous of its food and animal safety products. In many cases, the Company has developed unique antibodies capable of detecting microorganisms and residues at minute levels. The supply of these antibodies, and the proprietary techniques utilized
for their development, may offer better protection than the filing of patents. Such proprietary reagents are maintained in secure facilities and stored in more than one location to reduce exposure to complete destruction by natural disaster or other
means.

Patents and trademarks are applied for whenever appropriate. Since its inception, Neogen has acquired and received more than 50
patents and trademarks, and has several pending patents and trademarks. The patents expire at various times over the next 15 years.

A summary
of patents by product categories follows:

|                                          |  |     |    |  |               |  |    |            |  |  |           |

The Company does not expect that the near term expiration of any patent will have a significant effect on future results
of operations.

Management believes that Neogen has adequate protection as to proprietary rights for its products. However, it is aware that
substantial research has taken place at universities, governmental agencies and other companies throughout the world and that numerous patents have been applied for and issued. To the extent some of the Companys products may now, or in the
future, embody technologies protected by patents, copyrights or trade secrets of others, licenses to use such technologies may need to be obtained in order to continue to sell the products. These licenses may not be available on commercially
reasonable terms. Failure to obtain any such licenses may delay or prevent the sale of certain new or existing products. In addition, patent litigation is not uncommon. Accordingly, there can be no assurance that the Companys existing patents
will be sufficient to completely protect its proprietary rights.

One of the major areas affecting the success of biotechnology development
involves the time, cost and uncertainty surrounding regulatory approvals. Currently, Neogen products requiring regulatory approval include BotVax B, EqStim, ImmunoRegulin and Beta Star. The Companys general strategy is to select technical and
proprietary products that do not require mandatory approval to be marketed. Neogens rodenticide and disinfectant products are subject to registration in the United States and internationally.

Neogen utilizes third-party validations on many of its disposable test kits as a marketing tool to provide its customers with the proper assurances.
These include validation by the AOAC International, independently administered third-party, multi-laboratory collaborative studies and approvals by the U.S. Federal Grain Inspection Service and the U.S. Food Safety Inspection Service for the use of
Company products in their operations.

PRODUCTION AND SUPPLY

Neogen manufactures its products in Lansing, Michigan; Lexington, Kentucky; Randolph, Wisconsin; and Ayr, Scotland. As of May 31, 2011, there were approximately 296 full-time employees assigned to
manufacturing in these four locations, operating on one or two shifts; future demand increases could be accommodated by adding shifts. Management believes it could increase the current output of its primary product lines by more than 50% using the
current space available with a minimum of additional capital equipment. To meet current and future needs in Lexington, the Company entered into a purchase agreement in May 2011to purchase a production, warehouse and office building of 128,000 square
feet; it is currently renting 12,000 square feet in this facility. It is expected that this purchase will close in August 2011.

Manufacturing
of diagnostic tests for detection of natural toxins, pathogens, food allergens, spoilage organisms and pesticides, final kit assembly, quality assurance and shipping takes place in the Companys facilities in Lansing. Proprietary monoclonal and
polyclonal antibodies for the Neogens diagnostic kits are produced on a regular schedule in the Companys immunology laboratories. Other reagents are similarly prepared by the R&D employees. Manufacturing of diagnostic tests for the
presence of dairy antibiotics in milk is completed in the Companys Lansing facilities. Generally, final assembly and shipment of diagnostic test kits to customers in Europe are performed in the Companys Ayr, Scotland facility.

Assembly and shipment of electronic readers and disposable single-use samplers takes place in the Companys facilities in Lansing.

Dehydrated culture media products are manufactured in a FDA monitored facility in Lansing. Products are blended following strict formulations
or custom blended to customer specification and shipped directly to customers from Lansing.

Soleris instrument readers are produced and
shipped to customers mostly by third party vendors.

Manufacture of pharmacological diagnostic test kits, test kits for drug residues and of
animal health products takes place in the Companys facility in Lexington. In general, manufacturing operations including reagent manufacturing, quality assurance, final kit assembly and packaging are performed by Neogen personnel. Certain
animal health products that are purchased finished or that are toll manufactured by third party vendors and veterinary instruments are warehoused and shipped from the Companys Lexington facility. Other veterinary instruments are produced in
the Companys facilities in Lansing, and are generally then shipped to Lexington, for distribution to customers.

Manufacture of
rodenticides and certain cleaners and disinfectants takes place in Randolph. Manufacturing of rodenticides consists of blending technical material (active ingredient) with bait consisting principally of various grains. Certain cleaners and
disinfectants are manufactured in Randolph, while others are purchased from other manufacturers and sold, or toll manufactured by third parties.

Neogen maintains a Lansing-based USDA-approved manufacturing plant devoted to the production of the biologic products EqStim® and ImmunoRegulin®. P.
acnes seed cultures are added to media and then subjected to several stages of further processing resulting in a product that is filled and packaged within the facility. The Companys BotVax
®B vaccine is also produced in the Lansing facility utilizing Type B botulism seed cultures and a traditional
fermentation process. All completed biologic products are then shipped to Neogens Lexington facilities for inventory and distribution to customers.

With its April 2010 acquisition of GeneSeek, Inc., Neogen now maintains a commercial agricultural genetics laboratory in Lincoln, Neb. Through its laboratory services, GeneSeek empowers its customers to
speed genetic improvement efforts, as well as identify economically important diseases.

Neogen purchases component parts and raw materials
from more than 500 suppliers. Though many of these supplies are purchased from a single source in order to achieve the greatest volume discounts, the Company believes it has identified acceptable alternative suppliers for most of its key components
and raw materials. Shipments of products are generally accomplished within a 48-hour turnaround time. As a result of this quick response time, Neogens backlog of unshipped orders at any given time is not significant.

COMPETITION

Although competitors vary
in individual markets, management knows of no competitor that is pursuing Neogens fundamental strategy of developing and marketing a broad line of products, ranging from disposable tests and dehydrated culture media to veterinary
pharmaceuticals and veterinary instruments for a large number of food safety and animal safety concerns. For each of its individual products, the Company faces intense competition from companies ranging from small businesses to divisions of large
international companies. Some of these organizations have substantially greater financial resources than the Company. The Company competes primarily on the basis of ease of use, speed, accuracy, and other similar performance characteristics of its
products. The breadth of the Companys product line, the effectiveness of its sales and customer service organizations and pricing are also components in managements competitive plan.

##### Table of Contents

Future competition may become even more intense, including the development of changing technologies, which
could affect the marketability and profitability of Neogens products. The Companys competitive position also will depend on managements ability to develop proprietary products, attract and retain qualified scientific and other
personnel, develop and implement production and marketing plans and obtain patent protection. Additionally, the Company must have adequate capital resources to execute its strategy.

FOOD SAFETY:

Neogens Food Safety Division has strong distribution of its products using
Company employees in North America, Europe, Mexico and Brazil, and from an active and aggressive distributor group elsewhere. With one of the largest professional sales organizations in the industry, management believes that it maintains a general
competitive advantage as sales personnel are in a position to be in contact with customers and prospects more frequently than its competitors. Additionally, as an agricultural based company, Neogen has what is believed to be a unique insight into
the food industry as opposed to clinically based competition.

Competition for pathogen detection products includes traditional methods and
antibody and genetic based platforms. Neogens product offerings compete across the entire spectrum of methods. Competition for natural toxins and allergen detection products include instrumentation and antibody based tests. Generally, the
Companys products fall within the non-instrument category. While for these and other food safety products the Companys offerings will not always compete on all platforms in all markets, the products that are offered provide tests that
can be well utilized by most customers to meet their testing needs.

Besides its strong product offerings and extensive distributionnetwork,
the Company focuses its competitive advantage in the areas of customer service and speed and ease of use of its products. Additionally, by aggressively maintaining itself as a low cost producer, Neogen believes that it can be competitive with new
market entrants that may choose a low pricing strategy in an attempt to gain market share.

ANIMAL SAFETY:

Neogens Animal Safety Division faces no one competitor across the products and markets it serves. In the racing industry market, the Company
believes it holds a leading market share position. In the Life Sciences market, the Company competes against several other diagnostic and reagent companies with similar product offerings.

In the veterinary market, Neogen markets BotVax B®, the only USDA approved vaccine for the prevention of botulism Type B in horses. The Company competes on other key products through differentiated product performance
and superior customer and technical support. With some of its products, the Company provides solutions as a lower cost alternative and offers a private label option for its distributors.

Competition in the rodenticide market includes several companies of comparable size that offer products into similar market segments. The rodenticide retail market is dominated by a single brand. While
the technical materials used by the competing companies are similar, Neogen uses manufacturing and bait formula techniques to better draw rodents to the product and thereby improve overall product performance.

Several companies compete for sales in the disinfectant and cleaner product segment. Neogens products are sold through their distributor network
around the world, primarily to assist in the cleaning and disinfecting of animal production facilities.

Neogen competes in the retail market
by providing solutions to common retail problems  stock outs, wasted floor space, and inconsistent brand identity. The Company offers planograms and reordering systems to maximize turns and profitability for its retail customers.

Neogen added to its genomic capability through its April 2010 acquisition of GeneSeek, the leading commercial agricultural genetics laboratory in the
U.S. GeneSeek employs cutting-edge technology in the area of genomics. GeneSeek is not involved in cloning or the development of transgenic animals. Instead, the results of its technology allow the acceleration of natural selection through selective
breeding of traits such as disease resistance and meat quality. Competition comes mainly from service providers whose primary focus is the human and pharmaceutical industries.

GOVERNMENT REGULATION

A significant portion of the Neogens products and revenues are
affected by the regulations of various domestic and foreign government agencies, including the U.S. Department of Agriculture, the Environmental Protection Agency, and the U.S. Food and Drug Administration. Changes in these regulations could affect
revenues and/or costs of production and distribution.

Neogens development and manufacturing processes involve the use of certain
hazardous material, chemicals and compounds. Management believes that the Companys safety features for handling and disposing of such commodities comply with the standards prescribed by local, state and federal regulations. The Companys
current cost to comply with these regulations is not significant; however, changes in legislation or rules could be materially adverse to its business.

##### Table of Contents

The rodenticides, disinfectants and sanitizers manufactured and distributed by Neogen Corporation are
subject to Environmental Protection Agency regulations. In general, any international sale of the product must also comply with similar regulatory requirements in the country of destination. Each country has its own individual regulatory construct
with specific requirements (e.g., label in the language of the importing country). To the best of our knowledge pertinent products are in compliance with the appropriate federal and foreign regulations, in the respective country such products are
sold.

Dairy products used in National Conference on Interstate Milk Shipments (NCIMS) and other milk monitoring programs
are regulated by the FDA. Before products requiring FDA approval can be sold in the U.S., extensive product performance data must be submitted in accordance with FDA approved protocol administered by AOAC Research Institute (AOAC RI). Following
approval of a product by the FDA, the product must also be approved by NCIMS, an oversight body that includes state, federal and industry representatives. Our BetaStar® US dairy antibiotic residue testing product has been approved by the FDA, NCIMS, and AOAC RI. While some foreign countries accept AOAC RI approval as part of their
regulatory approval process, many countries have their own regulatory processes.

Many of the food safety diagnostic products of allergens,
spoilage organisms and mycotoxins do not require direct government approval. However, the Company has pursued AOAC approval for many of the products to enhance the marketability of products. Products for mycotoxin detection, which are used by
federal inspectors, must be approved by USDA. Neogen Corporation has obtained and retained the necessary approvals to conduct its current operations.

Neogens veterinary vaccine products and one pharmaceutical product require government approval to allow for lawful sales. The vaccine products are approved by United States Department of
Agriculture, Center for Veterinary Biologics (USDA-CVB) and the pharmaceutical product is approved by the FDA. The products, and the facilities in which they manufactured, are in a position of good standing with both agencies. The Company has had no
warning letters based on any review or inspection; the Company has had no recalls on any of these products; and the Company knows of no reason why its freedom to manufacture and market in the future is in any danger.

Other animal safety and food products generally do not require additional registrations or approvals. However, Neogen Corporations regulatory staff
routinely monitor amendments to current regulatory requirements to ensure compliance.

The Companys rodenticide products generally
require registration with U.S. governmental agencies at federal and state levels and with foreign governments.

EMPLOYEES

As of May 31, 2011 the Company employed 654 full-time persons. None of the employees are covered by collective bargaining agreements. There have been
no work stoppages or slowdowns due to labor-related problems. Management believes that its relationship with its employees is good. All employees having access to proprietary information have executed confidentiality agreements with the Company.



|ITEM 1A. | RISK FACTORS
|-------- | ------------

An investment in our common
shares involves a high degree of risk. The risks described below are not the only ones that an investor faces. Additional risks that are not yet known to us or that we currently think are immaterial could also impair our business, financial
condition or results of operations. If any of the following risks actually occurs, our business, financial condition or results of operations could be adversely affected.

Risks Relating to Our Business

Our business strategy is dependent on successfully
identifying and integrating acquisitions as well as promoting internal growth.

Our business has grown significantly over the past several
years as a result of both internal growth and acquisitions of existing businesses and their products. Identifying and pursuing acquisition opportunities, integrating these acquisitions into our business and managing their growth require a
significant amount of management time and skill. We cannot assure that we will be effective in identifying, integrating or managing any acquisition target in the future. Our failure to successfully integrate and manage any future acquisition may
have a material adverse effect on our operating results and financial condition.



12



---

##### Table of Contents

In addition, if we continue to experience growth in our business, our growth could place a significant
strain on our management, customer service, operations, sales and administrative personnel and other resources. To serve the needs of our existing and future customers, we will be required to recruit, train, motivate and manage qualified employees.
We have incurred and will continue to incur significant costs to retain qualified management, sales and marketing, engineering, production, manufacturing and administrative personnel, as well as expenses for marketing and promotional activities. Our
ability to manage our planned growth depends upon our success in expanding our operating, management and information and financial systems, which might significantly increase our operating expenses.

We might not be able to effectively manage our future growth, and if we fail to do so, our business, financial condition and results of operations would
be adversely affected.

The development of new products entails substantial risk of failure.

We are continually developing new products for which we believe there should be significant market demand. We cannot assure that we will successfully
develop commercially viable products, that the products will be developed on a timely basis to meet market demand or that the relevant market will be properly identified. If we expend substantial resources in developing an unsuccessful product,
operating results could be adversely affected.

Our international operations are subject to different product standards as well as other
operational risks.

In fiscal 2011, sales to customers outside of the United States accounted for 42.1% of the Companys total
revenue. We expect that our international business will continue to account for a significant portion of our total revenue. Foreign regulatory bodies may establish product standards different from those in the U.S. and with which the Companys
current products do not comply. Our inability to design products that comply with foreign standards could have a material adverse effect on our future growth. Other risks related to our sales to customers outside of the United States include the
possible disruption in transportation, difficulties in building and managing foreign distribution, fluctuation in the value of foreign currencies, import duties and quotas and unexpected economic and political changes in foreign markets. These
factors might adversely affect international sales and our overall financial performance.

The markets for our products are extremely
competitive, and our competitors may be able to utilize existing resource advantages to our detriment.

The markets in which the Company
competes are subject to rapid and substantial changes in technology and are characterized by extensive research and development and intense competition. Many of our competitors and potential competitors have greater financial, technical,
manufacturing, marketing, research and development and management resources than we do. These competitors might be able to use their resources, reputations and ability to leverage existing customer relationships to give them a competitive advantage
over us. They might also succeed in developing products that are at least as reliable and effective as our products, make additional measurements, are less costly than our products or provide alternatives to our products.

We are dependent on the agricultural marketplace, which is affected by factors beyond our control.

Our primary customers are in the agricultural and food production industries. Economic conditions affecting agricultural industries are cyclical and are
dependent upon many factors outside our control, including weather conditions or changes in consumption patterns or commodity prices. An economic downturn in the agricultural marketplace could adversely affect our sales.

Our quarterly operating results are subject to significant fluctuations.

We have experienced, and may experience in the future, significant fluctuations in our quarterly operating results. The mix of products sold and the acceptance of new products, in addition to other
factors, could contribute to this quarterly variability. We operate with relatively little backlog and have few long-term customer contracts. Substantially all of our product revenue in each quarter results from orders received in that quarter. In
addition, our expense levels are based, in part, on expectation of future revenue levels. A shortfall in expected revenue could, therefore, result in a disproportionate decrease in our net income.

Our success is highly dependent on our ability to obtain protection for the intellectual property utilized in our products.

Our success and ability to compete depends in part upon our ability to obtain protection in the United States and other countries for our products by
establishing and maintaining intellectual property rights relating to or incorporated into our technology and products. Patent applications filed by the Company may not result in the issuance of patents or, if issued, may not be issued in a form
that will be commercially advantageous to us. Even if issued, patents may be challenged, narrowed, invalidated or circumvented, which could



13



---

##### Table of Contents

limit our ability to stop competitors from marketing similar products or limit the length of time of patent protection we may have for our products. We also cannot assure that our nondisclosure
agreements, together with trade secrets and other common law rights, will provide meaningful protection for the Companys trade secrets and other proprietary information. Moreover, the laws of some foreign jurisdictions may not protect
intellectual property rights to the same extent as in the United States, and many companies have encountered significant difficulties in protecting and defending such rights in foreign jurisdictions. If we encounter such difficulties or we are
otherwise precluded from effectively protecting our intellectual property rights domestically or in foreign jurisdictions, we may incur substantial costs and our business, including our business prospects, could be substantially harmed.

From time to time, the Company has received notices alleging that the Companys products infringe third party proprietary rights. Whether the
manufacture, sale or use of current products, or whether any products under development would, upon commercialization, infringe any patent claim will not be known with certainty unless and until a court interprets the patent claim in the context of
litigation. If an infringement allegation is made against us, we may seek to invalidate the asserted patent claim and/or to allege non-infringement of the asserted patent claim. In order for us to invalidate a U.S. patent claim, we would need to
rebut the presumption of validity afforded to issue patents in the United States with clear and convincing evidence of invalidity, which is a high burden of proof. The outcome of infringement litigation is subject to substantial uncertainties, and
also the testimony of experts as to technical facts upon which experts may reasonably disagree. Our defense of an infringement litigation lawsuit could result in significant expense. Regardless of the outcome, infringement litigation could
significantly disrupt our marketing, development and commercialization efforts, divert our managements attention and consume our financial resources. In the event that we are found to infringe any valid claim in a patent held by a third party,
we may, among other things, be required to:



| |  |  | Pay damages, including up to treble damages and the other partys attorneys fees, which may be substantial;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | Cease the development, manufacture, importation, use and sale of products that infringe the patent rights of others, through a court-imposed sanction
called an injunction;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Expend significant resources to redesign our technology so that it does not infringe others patent rights, or to develop or acquire
non-infringing intellectual property, which may not be possible;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Discontinue manufacturing or other processes incorporating infringing technology; and/or
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | Obtain licenses to the infringed intellectual property, which may not be available to us on acceptable terms, or at all.
| | - |  | ------------------------------------------------------------------------------------------------------------------------

Any development or acquisition of non-infringing products or technology or licenses could require the expenditure of substantial time and other resources
and could have a material adverse effect on our business and financial results. If we are required to, but cannot, obtain a license to valid patent rights held by a third party, we would likely be prevented from commercializing the relevant product,
or from further manufacture, sale or use of the relevant product.

We are subject to substantial governmental regulation.

A portion of our products are regulated by various domestic and foreign government agencies, including the U.S. Department of Agriculture and the U.S.
Food and Drug Administration. Although less than 10% of our revenues are currently derived from products requiring government approval prior to sale, a significant portion of our revenues is derived from products used to monitor and detect the
presence of residues that are regulated by various government agencies. Furthermore, the Companys growth may be adversely affected by the implementation of new regulations.

We are dependent on key employees.

Our success depends, in large part, on our chairman,
president and other members of our management team. Our loss of any of these key employees could have a material adverse effect on the Company. We maintain certain incentive plans for key employees, and most of these employees have been with the
Company in excess of five years. However, we have not executed long-term employment agreements with any of these employees and do not expect to do so in the foreseeable future. Our success also depends, significantly, on our ability to continue to
attract such personnel. We cannot assure that we will be able to retain our existing personnel or attract additional qualified persons when required and on acceptable terms.

Our business may be subject to product liability claims.

The manufacturing and
distribution of the Companys products involve an inherent risk of product liability claims being asserted against us. Regardless of whether we are ultimately determined to be liable or our products are determined to be defective, we might
incur significant legal expenses not covered by insurance. In addition, product liability litigation could damage our reputation and impair our ability to market our products, regardless of the outcome. Litigation could also impair our ability to
retain product liability

insurance or make our insurance more expensive. Although the Company currently maintains liability insurance, we cannot assure that we will be able to continue to obtain such insurance on
acceptable terms, or that such insurance will provide adequate coverage against all potential claims. If we are subject to an uninsured or inadequately insured product liability claim, our business, financial condition and results of operations
could be adversely affected.

Market prices for securities of technology companies are highly volatile.

The market prices for securities of technology companies have been volatile in the past and could continue to be volatile in the future. Fluctuations in
our financial performance from period to period could have a significant impact on the market price of our common shares.

Operating
results could be negatively impacted by economic, political or other developments in countries in which we do business.

Future operating
results could be negatively impacted by unstable economic, political and social conditions, including but not limited to fluctuations in foreign currency exchange rates, political instability, or changes in the interpretation or creation of laws and
regulations or administrative actions in each of the countries where the Company conducts business, including the United States. Additionally, the Company operates in multiple income tax jurisdictions and must determine the appropriate
allocation of income to each of these jurisdictions based on current interpretations of complex income tax regulations. Income tax audits associated with the allocation of income and other complex issues may result in significant income tax
adjustments that could negatively impact the Companys future operating results.

|ITEM 7. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

The information in this Managements Discussion and Analysis of Financial Condition and Results of Operations contains both historical financial information and forward-looking statements. Neogen
Corporation management does not provide forecasts of future financial performance. While management is optimistic about the Companys long-term prospects, historical financial information may not be indicative of future financial results.

Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. Without limiting
the foregoing, the words believes, anticipates, plans, expects, seeks, estimates, and similar expressions are intended to identify forward-looking statements. There are a number
of important factors, including competition, recruitment and dependence on key employees, impact of weather on agriculture and food production, identification and integration of acquisitions, research and development risks, patent and trade secret
protection, government regulation and other risks detailed from time to time in the Companys reports on file at the Securities and Exchange Commission, that could cause Neogen Corporations results to differ materially from those
indicated by such forward-looking statements, including those detailed in this Managements Discussion and Analysis of Financial Condition and Results of Operations.

In addition, any forward-looking statements represent managements views only as of the day this Report on Form 10-K was first filed with the Securities and Exchange Commission and should not be
relied upon as representing managements views as of any subsequent date. While management may elect to update forward-looking statements at some point in the future, it specifically disclaims any obligation to do so, even if its views change.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The discussion and analysis of the Companys financial condition and results of operations are based on the consolidated financial statements that have been prepared in accordance with accounting
principles generally accepted in the United States. The preparation of these financial statements requires that management 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 ongoing basis, management evaluates the estimates, including those related to receivable allowances, inventories and intangible assets. These estimates are based on historical experience and on
various other assumptions that are believed to be 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.

The following critical accounting policies reflect
managements more significant judgments and estimates used in the preparation of the consolidated financial statements.

Revenue
Recognition

Revenue from sales of products and services is recognized when a purchase order has been received, the product has been
shipped or the service performed, the sales price is fixed and determinable, and collection of any receivable is probable. To the extent customer payment is received before all recognition criteria has been met, these revenues are initially deferred
and later recognized in the period that all recognition criteria has been met. Where right of return exists, allowances are made at the time of sale to reflect expected returns based on historical experience.

Accounts Receivable Allowance

Management attempts to minimize credit risk by reviewing customers credit history before extending credit and by monitoring credit exposure on a
regular basis. An allowance for possible losses on accounts receivable is established based upon factors surrounding the credit risk of specific customers, historical trends and other information. Collateral or other security is generally not
required for accounts receivable. Once a receivable balance has been determined to be uncollectible, that amount is written off against the reserve for uncollectible accounts.

Inventory

A reserve for obsolete and slow moving inventory has been established and is
reviewed at least quarterly based on an analysis of the inventory taking into account the current condition of the asset as well as other known facts and future plans. The amount of reserve required to record inventory at lower of cost or market may
be adjusted as conditions change. Product obsolescence may be caused by shelf-life expiration, discontinuance of a product line, replacement products in the marketplace or other competitive situations.

Goodwill and Other Intangible Assets

Management assesses goodwill and other non-amortizable intangible assets for possible impairment at least annually. Assessments indicated no impairment of these assets existed in each of 2011, 2010 and
2009. In the event of changes in circumstances that indicate the carrying value of these assets may not be recoverable, management will make an assessment at that time. Factors that could cause an impairment review to take place would include:



| |  |  | Significant under performance relative to expected historical or projected future operating results.
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | Significant changes in the use of acquired assets or strategy of the Company.
| | - |  | -----------------------------------------------------------------------------



| |  |  | Significant negative industry or economic trends.
| | - |  | -------------------------------------------------

When management determines that the carrying value of definite-lived intangible assets may not be recoverable based on the existence of one or more of the above indicators of impairment, the carrying
value of the reporting units net assets is compared to its fair value using undiscounted future cash flows of the reporting unit. If the carrying amounts of these assets are greater than the amount of undiscounted future cash flows, such
assets are reduced to their estimated fair value.

Equity Compensation Plans

ASC 718  Compensation  Stock Compensation addresses the accounting for share-based employee compensation. Further information on the Companys equity compensation plans, including inputs
used to determine fair value of options is disclosed in Note 5 to the consolidated financial statements. ASC 718 requires that share options awarded to employees and shares of stock awarded to employees under certain stock purchase plans are
recognized as compensation expense based on their fair value at grant date. The fair market value of options granted under the Companys stock option plans was estimated on the date of grant using the Black-Scholes option-pricing model using
assumptions for inputs such as interest rates, expected dividends, volatility measures and specific employee exercise behavior patterns based on statistical data. Some of the inputs used are not market-observable and have to be estimated or derived
from available data. Use of different estimates would produce different option values, which in turn would result in higher or lower compensation expense recognized.

To value options, several recognized valuation models exist. None of these models can be singled out as being the best or most correct one. The model applied by the Company is able to handle some of the
specific features included in the options granted, which is the reason for its use. If a different model were used, the option values would differ despite using the same inputs. Accordingly, using different assumptions coupled with using a different
valuation model could have a significant impact on the fair value of employee stock options. Fair value could be either higher or lower than the ones produced by the model applied and the inputs used.

RESULTS OF OPERATIONS

Executive Overview

Revenue of $172,683,000 in fiscal 2011 represented a 23% increase
compared to revenue of $140,509,000 in fiscal 2010. Net income for 2011 was $22,839,000, or $0.96 per fully diluted share, compared to $17,521,000, or $0.76 per fully diluted share, in fiscal 2010. Revenue, operating income and net income for the
2011 fiscal year each established new all-time highs. These results were achieved in a difficult business environment, both domestically and internationally. The Companys percentage of sales from customers outside the United States grew from
40% of total revenues in 2010 to 42% in 2011. Cash flow from operations for 2011 improved to $29 million, primarily a result of the profitability of the Company and its ability, through the use of systems and procedures, to control its use of
working capital.

Although there were no acquisitions during the fiscal year, the two acquisitions from the prior year performed strongly in
helping to increase revenues in 2011. Following a strong year in which allergen revenues increased by 50%, the BioKits acquisition pushed the food allergen product line to a second outstanding growth year, increasing sales by more than 44% in 2011.
The GeneSeek acquisition, made late in the 2010 fiscal year, made a positive impact by adding revenues of over $18 million in 2011 to the Company. Adding to the strong performance, Neogen Europe recorded a 27% revenue gain in 2011, following a 24%
gain in 2010.

Consolidated gross margins decreased from 51.9% in 2010 to 50.8% in 2011, due primarily to the impact of Geneseek, which under
its business model, operates at lower historical gross margins than the Companys other product lines, and to a lesser extent, product mix. Management continued a strong cost containment program begun in 2010. Operating expenses as a percentage
of revenues declined from 32.8% in 2010 to 30.1% in 2011 with increased utilization of fixed costs.

The Companys financial performance
continued to gain increased notice in the investment community in 2011. It continued its inclusion in the Russell 2000 Index and the Standard & Poors 600 Healthcare Index. Neogen was also named to Fortunes
Fastest Growing 100 list and was again named to Forbes Magazines annual list of The 200 Best Small Companies in America, for the sixth consecutive year and the ninth time in the last 11 years.

Year Ended May 31, 2011 Compared to Year Ended May 31, 2010

The Companys Food Safety segment revenues grew by 12% overall in 2011, with increases in each major product category compared to 2010. Organic
revenue growth was 9% in the segment, compared to the prior year. The increase in Natural Toxins, Allergens and Drug Residues of 10% in 2011 included strong contributions in Allergen revenues which increased 45% in comparison with 2010. Natural
toxin revenue was flat in 2011 compared with 2010, when cold and rainy conditions conducive to the production of the mycotoxin deoxynivalenol (DON) in much of the United States resulted in sales increases of 40% for these test kits. Drug residue
product related revenues increased by 5% compared with 2010, as worldwide concern over residue and toxin levels in human food and animal feed positively affected sales.

Bacterial and General Sanitation revenues increased in 2011 by 14% compared with 2010. While sales of AccuPoint readers and Soleris ® microbial detection instruments were relatively flat due to resistance toward the required initial capital investment for these units, sales of the associated
disposable AccuPoint samplers and Soleris vials from installed units remained strong.

Dehydrated Culture Media and Other revenues increased
by 15% in 2011, with strong sales to traditional lab accounts and increased international revenues.

Animal Safety revenues increased by 36%
overall and included a full year of DNA Testing revenues. On an organic basis, excluding revenues resulting from the GeneSeek acquisition, Animal Safety revenues increased 12% in comparison with fiscal year 2010. Life Sciences and Other revenues
increased 11% in 2011 with broad based increases from existing customers and new key accounts.

Despite the difficult economic conditions in
2011, vaccine revenues increased by 3% compared with 2010, as animal practitioners continued to utilize the Companys products.

Rodenticide and Disinfectant revenues increased by 17% in comparison with 2010. The Companys BioSentry line of cleaners and disinfectants continued
to gain market share and increased by 26% in comparison with 2010. The product line continues to be a strong synergistic fit as it is marketed with the Companys full line of biosecurity solutions.

Veterinary Instruments and Other products increased 7% for the year due to improvements in animal protein markets in the second half of the fiscal year.
Ideal Instruments product offerings, such as needles and syringe products, increased by 21% for the year, with broad based increases in several other product groups.

DNA Testing revenues, resulting from the purchase of GeneSeek Inc. in April 2010, contributed over $18,000,000 in its first full year with the Company.

Year Ended May 31, 2010 Compared to Year Ended May 31, 2009

The Companys Food Safety segment recorded a broad-based 2010 revenue increase of 25% to $76,454,000. Organic sales growth for this segment was 22% in the year ended May 31, 2010.

The increase in Natural Toxins, Allergens & Drug Residues resulted from strong organic sales and the contributions of the BioKits food allergen
product line that was acquired in December 2009. The allergen product line had another outstanding year of growth,

with sales increasing by 57%. The dramatic increase in sales of each of Neogens allergen tests is attributable to the aforementioned acquisition and to food producers increasing efforts to
ensure that inadvertent allergenic ingredients do not contaminate non-allergenic foods. Sales of Food Safetys oldest product line, its rapid tests to detect natural toxins in grain, also saw significant improvement for the year, as tests for
aflatoxin and deoxynivalenol (DON) improved by 40% compared to the prior year. Cool wet weather combined with an early frost experienced in the U.S. corn belt in 2009, led to sharp increases in demand for tests to detect these toxins. However,
continued worldwide interest in toxin levels in human food and animal feed has positively affected sales. Dollar sales of tests to detect drug residues increased by 24% from the prior year, as worldwide concern continued to increase.

Bacterial & General Sanitation sales had a good year despite several products that requires the customer to make a capital
investment, including AccuPoint readers and Soleris ® microbial detection instruments. Sales of these
products slowed in 2009 and in 2010 due to the impact of the economic downturn. However, sales of associated disposable AccuPoint samplers and Soleris vials continued strong growthproviding evidence of the continued use and acceptance of these
unique Food Safety products.

Dehydrated Culture Media & Other increased significantly during the year as a result of the continued
efforts of the sales and marketing staff in executing their sales plan and in gaining and retaining new customers.

Revenues from the
Companys Animal Safety segment grew 11% in 2010 compared to the prior year. The successful integration of the acquired DuPont line of disinfectants and cleaners, IDS drug residue diagnostics and GeneSeek, contributed significantly to Animal
Safetys revenue growth for the year. Organic growth was 4% in a very difficult overall market.

Life Sciences and Other sales increased
by 24% in 2010, primarily due to the successful integration of the IDS product line acquired in May 2009. Organic sales increases of the Life Sciences & Other products were limited as customers were affected by the economic downturn.

Sales of Neogens veterinary biologics, which include an equine vaccine against botulism and immune stimulant products were up 6% for
the year. Sales of vitamin injectibles into the livestock market were up 13% over the prior year. Evidence of the synergistic nature of the IDS diagnostic tests to pre-existing Neogen products was shown as we experienced an 18% increase in 2010 in
same store sales of tests to detect drug residues for the forensic market.

Even though a number of the Animal Safety customers continue to
feel the effects of a depressed animal protein market, this division did experience strong increases in sales of a number of products. Sales of rodenticides into domestic markets increased 27% on a year over year basis. Sales into international
markets of the same products increased 25%, as Neogen continues to grow its market share and new products gain market acceptance. Sales of Neogens line of cleaners and disinfectants also grew 10% in the year. The Companys efforts to
market its products as synergistic biosecurity solutions are gaining more traction.

Veterinary instrument and other sales decreased by 2% in
2010 in comparison with 2009 as many of these products are ultimately used by customers involved in the production of animal protein. This group of customers has been especially hit hard by the economic recession.

Cost of goods sold increased by 26% in 2011 and by 14% in 2010 in comparison with the prior year. This compares against a
23% and 18% increase in revenues in 2011 and in 2010. Expressed as a percentage of revenues, cost of goods sold was 49%, 48% and 50% in 2011, 2010, and 2009 respectively. The decline in 2011 gross margin percentage was primarily the result of the
business model of GeneSeek, which has lower gross margins than the other product lines of the Company.

Food Safety gross margins were 64%,
64% and 63% in 2011, 2010 and 2009, respectively. Changes in margins between periods relate primarily to changes in product mix. Margins also improved in 2011 and in 2010 from the effects of efficiencies resulting from investments in manufacturing
facilities and equipment.

Animal Safety gross margins were 37%, 38% and 37% in 2011, 2010 and 2009, respectively. Changes in margins between
periods relate primarily to product mix. Excluding the results of the Geneseek acquisition, margins in 2011 were 39%.

percentage of sales, sales and marketing expense decreased to 17% in 2011 from 19% in both 2010 and 2009. Management plans to continue to expand the Companys sales and marketing efforts both domestically and internationally and currently
expects related expenses to grow over time to approximately 20% of Company revenues.

General and administrative expenses increased by 12% in
2011 and by 17% in 2010. Increases in 2011 and 2010 resulted primarily from the absorption of acquisitions, as well as increased levels of operations and added amortization related to businesses acquired. These expenses have decreased from 10% to
9%, expressed as a percentage of sales, over the past three fiscal years. These declines have resulted from the fixed nature of many of these expenses, combined with significant increase in sales.

Research and development expenses increased by 9% in 2011 compared to 2010 and 37% in 2010 in comparison with 2009. As a percentage of revenue these
expenses were 4% in 2011, 5% in 2010 and 4% in 2009. Although some fluctuation in research and development expenses will occur, management expects research and development expenses to approximate 4-6% of revenues. Certain Company products require
relatively less investment in research and development expenses. Research and development expenses approximate 8% to 10% of revenues for products and product lines that are required to be supported by research and development.

During fiscal year 2011 and 2010, the Companys operating income increased by 33% and 31% compared to the respective
prior year. As a percentage of revenues it was 21%, 19% and 17% in 2011, 2010 and 2009 respectively. The Company has been successful in improving its operating income in 2011 and 2010 from revenue and gross margin growth from existing products and
acquisitions and from control of manufacturing, distribution and administrative costs.

Other income decreased by $1,038,000 in 2011, from $442,000 income in 2010 to ($596,000) expense in 2011 and decreased by
61% in 2010 in comparison with 2009. Other Income decreased in 2011 primarily due to a charge of $787,000 to Other Expense related to an increase in the secondary payment obligation for the GeneSeek acquisition. Interest income is a result of the
Companys increase in cash and cash equivalents and marketable securities in the periods, offset by decreased interest rates. By investing only in certificates of deposit and high quality A1P1 rated commercial paper maturing in one year or
less, the Company follows a very conservative investment philosophy which, in the current market, results in returns of less than 1%. Investment earnings were $95,000 in 2011, $81,000 in fiscal 2010 and $248,000 in 2009. Other income also included
$317,000, $181,000 and $429,000 in royalty income in 2011, 2010 and 2009 and $11,000 in 2011, $80,000 in 2010 and $355,000 in 2009 of gains from foreign currency transactions.

The tax provision was 35% of pretax income in 2011, 36% in 2010 and 36% in 2009. Fluctuations in the tax rate from the
35% corporate rate is due to changes in the mix of the localities where income is earned in any year, stock option plan deductions as a result of exercise of shares and tax credits. Other than rate, the increase in the tax provision is primarily a
function of the increase in pre-tax income of the Company.

FUTURE
OPERATING RESULTS

Neogen Corporations future operating results involve a number of risks and uncertainties. Actual events or
results may differ materially from those discussed in this report. Factors that could cause or contribute to such differences include, but are not limited to, the factors discussed below as well as those discussed elsewhere in this report.
Managements ability to grow the business in the future depends upon its ability to successfully implement various strategies, including:



| |  |  | developing, manufacturing and marketing new products with new features and capabilities;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | expanding the Companys markets by fostering increased use of Company products by customers;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | maintaining gross and net operating margins in changing cost environments;
| | - |  | --------------------------------------------------------------------------



| |  |  | strengthening sales and marketing activities in geographies outside of the U.S.;
| | - |  | --------------------------------------------------------------------------------



| |  |  | developing and implementing new technology development strategies; and
| | - |  | ----------------------------------------------------------------------



| |  |  | identifying and completing acquisitions that enhance existing businesses or create new business areas.
| | - |  | ------------------------------------------------------------------------------------------------------

FINANCIAL CONDITION AND LIQUIDITY

On May 31, 2011, the Company had $35,844,000 in cash and cash equivalents, $20,239,000 in marketable securities, working capital of $104,705,000 and
total equity of $188,978,000. The Company has a financing agreement with a bank providing for an unsecured revolving line of credit of $10,000,000 which matures on August 20, 2012. There were no advances against this line of credit during 2011,
2010 and 2009 and no balance outstanding at May 31, 2011 and 2010. Cash increased $13,038,000 during 2011, marketable securities increased by $20,239,000, cash provided from operations was $28,843,000 and stock option exercise proceeds provided
an additional $10,259,000 of cash. Additions to property and equipment and other non-current assets used cash of $7,796,000.

Accounts
receivable increased $1,201,000 or 4% when compared to May 31, 2010. This resulted from increased sales as a result of organic sales growth and acquisitions, offset by some decrease of average days outstanding. These accounts are being actively
managed and no losses thereon in excess of amounts reserved are currently expected. Days sales outstanding, a measurement of the time it takes to collect receivables, improved from 59 days at May 31, 2010 to 57 days at May 31, 2011.

##### Table of Contents

Inventory levels increased by 2% or $678,000 in 2011 as compared to 2010. Despite the higher sales volumes,
management was able to maintain a program to control inventory levels while supplying customers with shipments within 48 hours of placing an order. During 2011, the Company continued programs aimed at reducing inventory and expects to maintain those
programs into the future.

The Company is constructing a building in Randolph, Wisconsin to meet its warehousing needs, with expected
completion in the first quarter of FY-2012. The Company has entered an agreement to purchase a 132,000 square foot warehouse facility in Lexington, Kentucky, expected to close in August 2011. The facilities are generally believed to be adequate to
support existing operations in the short run. Both projects will be funded with available cash.

Neogen has been profitable from operations
for its last 73 quarters and has generated positive cash flow from operations during the period. However, the Companys current funds may not be sufficient to meet the Companys cash requirements to commercialize products currently under
development or its plans to acquire additional businesses, technology and products that fit within the Companys strategic plan. Accordingly, the Company may be required to or may choose to issue equity securities or enter into other financing
arrangements for a portion of the Companys future capital needs.

The Company is subject to certain legal and other proceedings in the
normal course of business that, in the opinion of management, will not have a material effect on its results of operations or financial position.

CONTRACTUAL OBLIGATIONS

The Company has the following contractual obligations due by
period:

NEW ACCOUNTING PRONOUNCEMENTS

See discussion of any New Accounting Pronouncements in Note 1 to Consolidated Financial Statements.



|ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS
|-------- | -----------------------------------------------------------

The Company has moderate interest rate and foreign exchange rate risk exposure and no long-term fixed rate investments or borrowings. The Companys primary interest rate risk is due to potential
fluctuations of interest rates for variable rate borrowings.

Because Neogen markets and sells its products throughout the world, it could be
affected by weak economic conditions in foreign markets that could reduce the demand for its products. Sales in certain foreign countries as well as certain expenses related to those sales are transacted in currencies other than the U.S. dollar. The
Companys operating results are primarily exposed to changes in exchange rates between the U.S. dollar and the British Pound and the Euro. When the U.S. dollar weakens against foreign currencies, the dollar value of sales denominated in foreign
currencies increases. When the U.S. dollar strengthens, the opposite situation occurs.

Neogen has assets, liabilities and operations outside
of the United States that are located primarily in Ayr, Scotland where the functional currency is the British Pound Sterling. To a lesser extent it also has assets, liabilities and operations in Mexico where the functional currency is the Mexican
Peso and in Brazil where the functional currency is the Real. The Companys investment in its foreign subsidiaries are considered long-term; accordingly, it does not hedge the net investment nor does it generally engage in other foreign
currency hedging activities due to the insignificance of these balances to the Company as a whole. It does, however, use strategies to reduce current exposure to currency fluctuations.

Managements Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rues 13-a-15(f) and 15d-15(f). Under the supervision
and with the participation of the companys management, including the Chief Executive Officer and Chief Financial Officer, an evaluation was conducted as to the effectiveness of internal control over financial reporting as of May 31, 2011,
based on the framework in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that evaluation, management concluded that internal control over financial reporting was
effective as of May 31, 2011. The effectiveness of internal control over financial reporting as of May 31, 2011, has been audited by Ernst & Young, LLP, an independent registered public accounting firm, as stated in its
attestation report, which is included in Item 8 and is incorporated into this Item 9A by reference.

Changes in Internal Control
over Financial Reporting.

No changes in our internal control over financial reporting were indentified as having occurred during the

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of Neogen Corporation

We have audited Neogen Corporations internal control over financial reporting as of May 31, 2011, based on criteria established in Internal ControlIntegrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Neogen Corporations management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the
effectiveness of internal control over financial reporting included in the accompanying Managements Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the companys internal
control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included
obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing
such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process 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. A companys internal control over financial reporting includes those policies and procedures that
(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors
of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 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.

In our opinion, Neogen Corporation maintained, in all material respects, effective internal control over financial reporting as of May 31, 2011,
based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United
States), the consolidated balance sheets of Neogen Corporation as of May 31, 2011 and 2010, and the related consolidated statements of income, equity, and cash flows for each of the three years in the period ended May 31, 2011, and our
report dated July 29, 2011 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of Neogen Corporation

We have audited the accompanying consolidated balance sheets of Neogen Corporation (the Company) as of May 31, 2011 and 2010, and the related consolidated statements of income, equity, and cash flows
for each of the three years in the period ended May 31, 2011. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the
financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable
basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated
financial position of Neogen Corporation at May 31, 2011 and 2010, and the consolidated results of its operations and its cash flows for each of the three years in the period ended May 31, 2011, in conformity with U.S. generally accepted
accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United
States), the effectiveness of Neogen Corporations internal control over financial reporting as of May 31, 2011, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of
the Treadway Commission and our report dated July 29, 2011 expressed an unqualified opinion thereon.

Neogen Corporation and Subsidiaries

Notes to Consolidated Financial Statements



|1. | Summary of Accounting Policies
|-- | ------------------------------

Nature of
Operations

Neogen Corporation develops, manufactures, and markets a diverse line of products dedicated to food and animal safety.

Basis of Consolidation

The consolidated
financial statements include the accounts of Neogen Corporation and its subsidiaries (collectively, the Company), all of which are wholly owned, with the exception of Neogen Latinoamerica S.A.P.I. DE C.V., which is 60% owned and Neogen do Brazil,
which is 98% owned. Noncontrolling interest represents the noncontrolling owners proportionate share in the equity of the Companys majority owned subsidiaries. The noncontrolling owners proportionate share in the income or losses
of the Companys majority owned subsidiaries is included in other income, net in the statements of income.

All intercompany accounts and
transactions have been eliminated in consolidation.

Share and per share amounts reflect the December 15, 2009 3-for-2 stock split as if
it took place at the beginning of the periods presented.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the
consolidated financial statements and accompanying notes. Actual results could differ from these estimates.

Comprehensive Income

Comprehensive income represents net income and any revenues, expenses, gains and losses that, under U.S. generally accepted accounting principles, are
excluded from net income and recognized directly as a component of equity. Accumulated other comprehensive income (loss) consists solely of foreign currency translation adjustments.

Accounts Receivable and Concentrations of Credit Risk

Financial instruments which potentially
subject the Company to concentrations of credit risk consist principally of accounts receivable. Management attempts to minimize credit risk by reviewing customers credit history before extending credit and by monitoring credit exposure on a
regular basis. An allowance for possible losses on accounts receivable is established based upon factors surrounding the credit risk of specific customers, historical trends and other information. Collateral or other security is generally not
required for accounts receivable. Once a receivable balance has been determined to be uncollectible, that amount is written off against the reserve for uncollectible accounts. One customer accounted for more than 10% of accounts receivable at
May 31, 2010. As of May 31, 2010 the balance due from that customer was $2,608,000, or 10% of the total of all outstanding accounts receivable.

The Company maintained a valuation allowance for accounts receivable of $800,000 at May 31, 2011 and $600,000 at May 31, 2010. Expenses related to uncollectable accounts and allowance
adjustments were $430,000, $242,000 and $199,000 in 2011, 2010 and 2009, respectively. Write-offs were $230,000, $242,000 and $99,000 in 2011, 2010 and 2009, respectively.

Fair Value of Financial Instruments

The carrying amounts of the Companys financial
instruments other than cash equivalents and marketable securities, which include accounts receivable, accounts payable, and accrued expenses, approximate fair value based on either their short maturity or current terms for similar instruments.

Notes to Consolidated Financial Statements



Cash and Cash Equivalents

Cash and cash equivalents consist of bank demand accounts, savings
deposits and certificates of deposit with original maturities of 90 days or less. Cash equivalents were $35,844,000 and $22,806,000 at May 31, 2011 and 2010, respectively. The carrying value of these assets approximates fair value.

Fair Value Measurements

Fair value
measurements are determined based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants exclusive of any transaction costs. The Company utilizes a fair value
hierarchy based upon the observability of inputs used in valuation techniques as follows:



|         |  |                                                                                                                                   
|-------- |  | ----------------------------------------------------------------------------------------------------------------------------------
|Level 1: |  | Observable inputs such as quoted prices in active markets;                                                                        
|Level 2: |  | Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and                        
|Level 3: |  | Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Marketable Securities

The Company has marketable securities held by banks or broker-dealers consisting of short-term domestic certificates of deposit and commercial paper rated at least A-1/P-1 with maturities between 91 days
and one year. Outstanding marketable securities at May 31,

2011 were $20,239,000; there were no marketable securities outstanding at
May 31, 2010. These securities are classified as held for sale. The primary objective of the Companys short-term investment activity is to preserve capital for the purpose of funding operations; short-term investments are not entered into
for trading or speculative purposes. The fair values are based on quoted market prices for the marketable securities in active markets with sufficient volume and frequency (Level 1).

Inventories

Inventories are stated at the lower of cost, determined on the first-in, first-out
method, or market. The components of inventories were as follows:



|                                      |  |        |        |  |      |   |        | 
|------------------------------------- |  | ------ | ------ |  | ---- | - | ------ | 
|                                      |  | May 31 |       
|(in thousands)                        |  | 2011   |        |  | 2010 |  
|Raw materials                         |  | $      | 12,125 |  |      | $ | 11,815 | 
|Work-in-proces                        |  |        | 2,192  |  |      |   | 1,958  | 
|Finished and purchased finished goods |  |        | 17,677 |  |      |   | 17,543 | 
|                                      |  |        |        |  |      |   |        | 
|                                      |  | $      | 31,994 |  |      | $ | 31,316 | 
|                                      |  |        |        |  |      |   |        | 

No less frequently than quarterly, inventory is analyzed for slow moving and obsolete inventory and the valuation
allowance is adjusted as required. Write offs against the allowance are not separately identified. The valuation allowance for inventory was $1,150,000 and $1,000,000 at May 31, 2011 and 2010, respectively.

Property and Equipment

Property and equipment
is stated at cost. Expenditures for major improvements are capitalized while repairs and maintenance are charged to expense. Depreciation is provided on the straight-line method over the estimated useful lives of the respective assets, which are
generally seven to 39 years for buildings and improvements and three to five years for furniture, machinery and equipment. Depreciation expense was $3,185,000, $2,734,000 and $2,560,000 in 2011, 2010 and 2009, respectively.

Goodwill and Other Intangible Assets

Goodwill
represents the excess of purchase price over fair value of tangible net assets of acquired businesses after amounts are allocated to other identifiable intangible assets. In general, goodwill is amortizable for tax purposes over 15 years. Other
intangible assets include customer relationships, trademarks, licenses, trade names and patents. Amortizable intangible assets are amortized on either an

accelerated or a straight-line basis over five to 20 years. The Company reviews the carrying amounts of goodwill and other non-amortizable intangible assets annually to determine if such assets
may be impaired. If the carrying amounts of these assets are deemed to be less than fair value based upon a discounted cash flow analysis and comparison to comparable EBITDA multiples of peer companies, such assets are reduced to their estimated
fair value and a charge is made to operations. The remaining weighted-average amortization period for customer based intangibles and other intangibles is 13 and 10 years, respectively, at May 31, 2011.

Long-lived Assets

Management reviews the
carrying values of its long-lived assets for possible impairment whenever events or changes in business conditions indicate that the carrying amount of the assets may not be recoverable. Impairment is first evaluated by comparing the carrying value
of the long-lived assets to undiscounted future cash flows over the remaining useful life of the assets. If the undiscounted cash flows are less than the carrying value of the assets, the fair value of the long-lived assets is determined, and if
lower than the carrying value, impairment is recognized through a charge to operations.

Reclassifications

Certain amounts in the 2010 and 2009 financial statements have been reclassified to conform to the 2011 presentation.

Stock Options

At May 31, 2011, the
Company had stock option plans which are described more fully in Note 5.

The weighted-average fair value per share of stock options granted
during 2011, 2010 and 2009, estimated on the date of grant using the Black-Scholes option pricing model, was $8.66, $6.35 and $5.44 respectively. The fair value of stock options granted was estimated using the following weighted-average assumptions:



|                                |  |                   |           |   |      |  |           |      |  |  |           |  
|------------------------------- |  | ----------------- | --------- | - | ---- |  | --------- | ---- |  |  | --------- | -
|                                |  | Year ended May 31 |          
|                                |  | 2011              |           |   | 2010 |  |           | 2009 | 
|Risk-free interest rate         |  |                   | 1.68      | % |      |  | 2.0       | %    |  |  | 2.9       | %
|Expected dividend yield         |  |                   | 0         | % |      |  | 0         | %    |  |  | 0         | %
|Expected stock price volatility |  |                   | 35.8      | % |      |  | 37.8      | %    |  |  | 32.8      | %
|Expected option life            |  |                   | 4.0 years |   |      |  | 4.0 years |      |  |  | 4.0 years |  

The risk-free interest rate for periods within the expected life of options granted is based on the United States
Treasury yield curve in effect at the time of grant. Expected stock price volatility is based on historical volatility of the Companys stock. The expected option life, representing the period of time that options granted are expected to be
outstanding, is based on historical option exercise and employee termination data. The Company recognizes the cost of stock options using the accelerated method over their requisite service periods which the Company has determined to be the vesting
periods.

Revenue Recognition

Revenue from sales of products and services is recognized when a purchase order has been received, the product has been shipped or the service has been
performed, the sales price is fixed and determinable, and collection of any resulting receivable is probable. To the extent customer payment is received before all recognition criteria has been met, these revenues are initially deferred and later
recognized in the period that all recognition criteria has been met. Where right of return exists, allowances are made at the time of sale to reflect expected returns based on historical experience.

Shipping and Handling Costs

Shipping and
handling costs that are charged to and reimbursed by the customer are recognized as sales, while the related expenses incurred by the Company are recorded in sales and marketing expense and totaled $5,211,000, $4,494,000 and $4,266,000 in 2011, 2010
and 2009, respectively.

Income Taxes

The Company accounts for income taxes using the liability method. Under this method,
deferred income tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates in effect for the years in which the differences are
expected to reverse. Deferred income tax expense represents the change in net deferred income tax assets and liabilities during the year.

The
Companys foreign subsidiaries are comprised of Neogen Europe (wholly owned subsidiary), Neogen Latin America (60% owned by Neogen) and Neogen do Brazil (98% owned by Neogen ). The Companys historical experience with these entities Based
on historical experience as well as the Companys future plans, earnings from these subsidiaries are expected to be re-invested indefinitely for future expansion and working capital needs. Furthermore, the Companys domestic operations
have historically produced sufficient operating cash flow, to mitigate the need to remit foreign earnings. On an annual basis, the Company evaluates the current business environment and whether any new events or other external changes might require
a reevaluation of the decision to indefinitely re-invest foreign earnings. At May 31, 2011 unremitted earnings of the foreign subsidiaries were $7,190,000.

Research and Development Costs

Research and Development costs are expensed as incurred.

Advertising Costs

Advertising
costs are expensed as incurred and totaled $677,000, $633,000 and $603,000 in 2011, 2010 and 2009, respectively.

Net Income Per Share

Basic net income per share is based on the weighted average number of common shares outstanding during each year. Diluted earnings per share
is based on the weighted average number of common shares and dilutive potential common shares outstanding. The Companys dilutive potential common shares outstanding during the years result entirely from dilutive stock options and warrants. The
following table presents the net income per share calculations:

In 2011 and 2009, 12,000 and 417,000 options, respectively, were excluded from the computations of net income per share
as the option exercise prices exceeded the average market price of the common shares. No options were excluded in 2010.

New Accounting
Pronouncements

Recent ASUs issued by the FASB and guidance issued by the SEC did not, or are not believed by management to, have a
material effect on the Companys present or future consolidated financial statements.

|2. | Goodwill and Other Intangible Assets
|-- | ------------------------------------

The
Company follows the provisions of ASC 350  Intangibles Goodwill and Other (ASC 350). ASC 350 prohibits the amortization of goodwill and intangible assets with indefinite lives and requires that the Company evaluate these intangibles for
impairment on an annual basis. Management has completed the required annual impairment tests of goodwill and intangible assets with indefinite lives as prescribed by ASC 350 as of the first day of the fourth quarter of 2011 and determined that
recorded amounts were not impaired and that no write-down was necessary.

The following table summarizes goodwill by business segment:

Neogen Corporation and Subsidiaries

Notes to Consolidated Financial Statements





|3. | Business Combinations
|-- | ---------------------

The Consolidated
Statements of Income reflect the results of operations for business acquisitions since the respective dates of purchase. All are accounted for using the purchase method.

On June 3, 2008, Neogen Corporation formed a subsidiary in Mexico, Neogen Latinoamerica S.A.P.I. DE C.V. to acquire its former distributor. The new business is 40% owned by Neogen Corporations
former Mexican distributor in Mexico, with the remainder owned by Neogen. The new company distributes the Companys food and animal safety products throughout Mexico. The consideration of $672,000 was allocated $462,000 to current assets,
$30,000 to fixed assets and the remainder to intangible assets (estimated useful lives of 10 years).

On June 30, 2008, Neogen
Corporation purchased a disinfectant business from DuPont Animal Health Solutions. The products of this business are used in animal health hygiene applications. Assets acquired include 14 different product formulations, associated registrations,
patents, trademarks, and other intangibles (estimated useful lives of 5-15 years). As a part of the acquisition, the Company obtained the right to distribute certain other related DuPont products in North America. DuPont distributes certain of the
newly acquired Neogen products in certain international markets. Consideration for the purchase was $7,000,000, and $5,193,000 was allocated to goodwill, $1,186,000 to customer based intangibles and $621,000 to trademarks and patents. This
acquisition has been integrated into the Lexington, Kentucky, operations and has been a strong synergistic fit with the Companys Animal Safety segment.

On May 4, 2009, Neogen Corporation acquired International Diagnostics Systems Corporation (IDS), a St. Joseph, Michigan based developer, manufacturer and marketer of test kits to detect drug residues
in food and animal feed, and drugs in forensic and animal samples. Consideration for the purchase was $3,955,000. The allocation included cash acquired of $493,000, net current assets of $691,000, fixed assets of $300,000, deferred tax liabilities
of $400,000, goodwill (not deductible for tax purposes) and intangible assets (estimated useful lives of 5-20 years) of $3,300,000 including customer based intangibles of $1,090,000. The acquisition has been integrated into the Animal Safety
segment.

On December 1, 2009, the Company purchased the BioKits food safety allergen test kits business of Gen-Probe Incorporated.
Consideration for the purchase, which was determined through arms length negotiations, approximated $6.5 million in cash. The final allocation of the purchase price included net current assets of $770,000, fixed assets of $163,000 and intangible
assets of $5,522,000. The valuation of the identifiable intangible assets acquired was based on managements estimates, currently available information and reasonable and supportable assumptions. The allocation was generally based on the fair
value of these assets determined using the income approach. These fair value measurements were based on significant inputs not observable in the market and thus represent Level 3 fair value measurements. The acquisition has been integrated into the
Food Safety segment.

On April 1, 2010, Neogen Corporation acquired GeneSeek, Inc. of Lincoln, Nebraska, a leading commercial
agricultural genetic laboratory. GeneSeeks technology employs high-resolution DNA genotyping for identity and trait analysis in a variety of important animal and agricultural plant species. Consideration for the purchase was $14,050,000 in
cash and secondary payment obligations of up to $7,000,000. The allocation of the purchase price included accounts receivable of $1,923,000, inventory of $1,512,000, fixed assets of $847,000, current liabilities of $905,000, deferred tax liabilities
of $2,530,000, secondary payment liabilities of $3,583,000, and the remainder to goodwill (not deductible for tax purposes) and other intangible assets (with estimated lives of 5-20 years). The allocation was generally based on the fair value of
these assets determined using the income approach. These fair value measurements were based on significant inputs not observable in the market and thus represent Level 3 fair value measurements. The secondary payment was based upon future operating
results of the GeneSeek business through 2013, and payable annually over a three year period, measured at fair value, and is considered a Level 3 fair value measurement. The Company recorded a charge within other income (expense) of approximately
$787,000 for the year ended May 31, 2011, representing the increase from its original estimate in fair value of the secondary payment liability. As of May 31, 2011, the balance of the secondary payment liability recorded was approximately
$4,370,000. A payment of $1,856,000 was made in June, 2011 to the former owners of Geneseek, comprised of $1,537,000 for the first year contingent payment and an additional $319,000 for inventory purchased post acquisition and settlement of other
liabilities. The acquisition has been integrated into the Animal Safety segment.

interest or penalties relative to unrecognized tax benefits be necessary, such accruals will be reflected within income tax accounts. For the majority of tax jurisdictions, the Company is no longer subject to U.S. Federal, State and local or non
U.S. income tax examinations by tax authorities for fiscal years before 2006. The Company is under audit by the Internal Revenue Service for its 2009 fiscal year.



|7. | Commitments and Contingencies
|-- | -----------------------------

The Company is
involved in environmental remediation and monitoring activities at its Randolph, Wisconsin manufacturing facility and accrues for related costs when such costs are determined to be probable and estimable. The Company is currently expensing annual
costs of remediation which have ranged from $50,000 to $105,000 per year over the past five years. The Companys estimated liability for these costs of $916,000 at May 31, 2011 and 2010, measured on an undiscounted basis over an estimated
period of 15 years, is recorded within other long term liabilities in the consolidated balance sheet.

The Company entered into an agreement
in May 2011 to purchase a facility in Lexington, Kentucky for $4,950,000; this transaction is expected to close in August 2011. This purchase will provide the Company an additional 116,000 square feet of office, production and warehouse space.

The Company has agreements with unrelated third parties that provide for the payment of royalties on the sale of certain products. Royalty
expense under the terms of these agreements was $1,561,000, $1,337,000 and $1,184,000 for 2011, 2010 and 2009, respectively.

The Company has
agreements with unrelated third parties that provide for guaranteed minimum royalty payments for certain technologies, as follows: 2012-$100,000, 2013-$250,000, 2014-$350,000, and 2015 and later-$500,000.

The Company leases office and manufacturing facilities under noncancelable operating leases. Rent expense for 2011, 2010 and 2009 was $477,000, $428,000 and $336,000, respectively. Future minimum rental
payments for these leases over their remaining terms are as follows: 2012$ 356,000; and 2013$87,000.

The Company is subject to
certain legal and other proceedings in the normal course of business that, in the opinion of management, will not have a material effect on its future results of operations or financial position.



|8. | Defined Contribution Benefit Plan
|-- | ---------------------------------

The Company
maintains a defined contribution 401(k) benefit plan covering substantially all employees. Employees are permitted to defer up to IRS limits, with the Company matching 100% of the first 3% deferred and 50% of the next 2% deferred. The Companys
expense under this plan was $733,000, $622,000 and $542,000 in 2011, 2010 and 2009, respectively.



|9. | Segment Information
|-- | -------------------

The Company has two
reportable segments: Food Safety and Animal Safety. The Food Safety segment produces and markets diagnostic test kits and related products used by food producers and processors to detect harmful natural toxins, foodborne bacteria, allergens and
levels of general sanitation. The Animal Safety segment is primarily engaged in the production and marketing of products dedicated to animal safety, including a complete line of consumable products marketed to veterinarians and animal health product
distributors and provides genetic identification services. Additionally, the Animal Safety segment produces and markets rodenticides and disinfectants to assist in control of rodents and disease in and around agricultural, food production and other
facilities.

These segments are managed separately because they represent strategic business units that offer different products and require
different marketing strategies. The Company evaluates performance based on total sales and operating income of the respective segments. The accounting policies of the segments are the same as those described in Note 1.

Segment information is as follows:
