ITEM 1.

BUSINESS

Overview

Meridian is a fully-integrated life science company whose principal businesses are (i) the development, manufacture, sale and distribution of diagnostic test kits, primarily for certain respiratory, gastrointestinal, viral and parasitic infectious diseases, (ii) the manufacture and distribution of bulk antigens, antibodies, and reagents used by researchers and other diagnostic manufacturers and (iii) the contract development and manufacture of proteins and other biologicals for use by biopharmaceutical and biotechnology companies engaged in research for new drugs and vaccines. By exploiting revenue opportunities across research, clinical diagnostics, and therapeutics, we strive to maximize revenues, efficiently invest in research and development, and increase profitability of our manufacturing operations.

Operating Segments

Our reportable operating segments are US Diagnostics, European Diagnostics, and Life Science. The US Diagnostics operating segment consists of manufacturing operations in Cincinnati, Ohio, and the sale and distribution of diagnostics test kits in the US and countries outside of Europe, Africa and the Middle East. The European Diagnostics operating segment consists of the sale and distribution of diagnostics test kits in Europe, Africa and the Middle East. The Life Science operating segment consists of manufacturing operations in Memphis, Tennessee, Saco, Maine, and Boca Raton, Florida, and the sale and distribution of bulk antigens, antibodies, and bioresearch reagents domestically and abroad. The Life Science operating segment also includes the contract development and manufacture of proteins and other biologicals for use by biopharmaceutical and biotechnology companies engaged in research for new drugs and vaccines. Financial

information for Meridian’s operating segments is included in Note 9 to the consolidated financial statements contained herein.

Our primary source of domestic and international revenues continues to be core diagnostic products, which represented 80% of consolidated net sales for fiscal 2007. Our diagnostic products provide accuracy, simplicity, and speed, enable early diagnosis and treatment of common, acute medical conditions, and provide for better patient outcomes at reduced costs. We target diagnostics for disease states that (i) are acute conditions where rapid diagnosis impacts patient outcomes, (ii) have opportunistic demographic and disease profiles, (iii) are underserved by current diagnostic products, and (iv) have difficult sample handling requirements. This approach has allowed us to establish significant market share in our target disease states.

US Diagnostics Operating Segment

Overview

Our US Diagnostics operating segment’s business focuses on the development, manufacture, sale and distribution of diagnostic test kits, primarily for certain respiratory, gastrointestinal, viral and parasitic infectious diseases. In addition to diagnostic test kits, products also include transport media that store and preserve specimen samples from patient collection to laboratory testing. Third-party sales for this operating segment were $74,845,000, $65,721,000 and $53,485,000 for fiscal 2007, 2006 and 2005, respectively, reflecting a three-year compound annual growth rate of 16%. As of September 30, 2007, our US Diagnostics operating segment had 250 employees.

Our diagnostic test kits utilize immunodiagnostic technologies, which test samples of blood, urine, stool, and other body fluids or tissue for the presence of antigens and antibodies of specific infectious diseases. Specific immunodiagnostic technologies used in our diagnostic test kits include enzyme immunoassay, immunofluorescence, particle agglutination/aggregation, immunodiffusion, complement fixation, and chemical stains.

Our diagnostic products are used principally in the detection of respiratory diseases, such as pneumonia, valley fever, influenza, and Respiratory Syncytial Virus (RSV); gastrointestinal diseases, such as stomach ulcers (H. pylori), antibiotic-associated diarrhea (C. difficile) and pediatric diarrhea (Rotavirus and Adenovirus); viral diseases, such as Mononucleosis, Herpes Simplex, Chicken Pox and Shingles (Varicella-Zoster) and Cytomegalovirus (organ transplant infections); and parasitic diseases, such as Giardiasis, Cryptosporidiosis and Lyme. The primary markets and customers for these products are reference laboratories, hospitals, and physicians’ offices.

Market Trends

The global market for infectious disease tests continues to expand as new disease states are identified, new therapies become available, and worldwide standards of living and access to health care improve. More importantly, within this market there is a continuing shift from conventional testing, which requires highly trained personnel and lengthy turnaround times for test results, to more technologically advanced testing which can be performed by less highly trained personnel and completed in minutes or hours.

The increasing pressures to contain total health care costs have accelerated the increased use of diagnostic testing. With rapid and accurate diagnoses of infectious diseases, physicians can pinpoint appropriate therapies quickly, leading to faster recovery, shorter hospital stays and lower treatment expense. In addition, these pressures have led to a major consolidation among reference laboratories and the formation of multi-hospital alliances that have reduced the number of institutional customers for diagnostic products and resulted in changes in buying practices. Specifically, multi-year exclusive or primary source marketing or distribution contracts with institutional customers have become more common, replacing less formal distribution arrangements of shorter duration and involving lower product volumes.

Sales and Marketing

Our US Diagnostics operating segment’s sales and distribution network consists of a direct sales force in the US and independent distributors in the US and abroad. The direct sales force consists of one senior director of sales, three regional sales managers, one director of corporate health systems, one manager of corporate health systems, one director of health plan and payer markets, one international distribution manager, 25 technical sales representatives, and three inside sales representatives. We utilize two primary independent distributors in the US, who accounted for 51% of the US Diagnostics operating segment’s third-party sales in fiscal 2007. We manage the selling effort for key customers where these independent distributors are utilized.

Consolidation of the US healthcare industry is expected to continue and potentially affect our customers. Industry consolidation puts pressure on pricing and aggregates buying power. In response, we have looked to

multi-year supply agreements with consolidated healthcare providers and major reference laboratories to stabilize pricing.

Products and Markets

We have expertise in the development and manufacture of products based on multiple core diagnostic technologies, each of which enables the visualization and identification of antigen/antibody reactions for specific pathogens. Our product technologies include enzyme immunoassay, immunofluorescence, particle agglutination/aggregation, immunodiffusion, complement fixation and chemical stains. As a result, we are able to develop and manufacture diagnostic tests in a variety of formats that satisfy customer needs and preferences, whether in a hospital, commercial or reference laboratory or alternate site location. Our product offering consists of approximately 140 medical diagnostic products. Our products generally range in list price from $1 per test to $33 per test.

Research and Development

Our US Diagnostics operating segment’s research and development organization consists of 14 research scientists with expertise in biochemistry, immunology, mycology, bacteriology, virology, and parasitology. Research and development expenses for the US Diagnostics operating segment for fiscal 2007, 2006 and 2005 were $4,571,000, $3,342,000 and $3,043,000, respectively. This research and development organization focuses its activities on new applications for our existing technologies, improvements to existing products and development of new technologies. Research and development efforts may occur in-house or with collaborative partners. We believe that new product development is a key source for sustaining revenue growth. Our internally developed products include Premierä Platinum HpSA PLUS, Premierä Toxins A & B, and ImmunoCard^Ò Toxins A & B, which together accounted for 39% of our US Diagnostics operating segment’s third-party sales during fiscal 2007.

We believe that the use of collaborative partners in the development of new products will complement our internal research and development staff in a manner that allows us to bring products to market more quickly than if development were to occur solely on an internal basis. During August 2006, we entered into a partnership agreement with the Performance & Life Science Chemicals Division of Merck KGaA, Darmstadt, Germany for the development of new clinical assays. Our first product under this agreement, ImmunoCard STAT! ^® EHEC, was launched during the second quarter of fiscal 2007.

Over the last 15 months, we have begun exploring and developing a molecular-based diagnostic testing technology to complement our existing antigen/antibody-based testing technologies. This first look at molecular-based testing started in October 2006, when we executed a license agreement with Eiken Chemical Co., Ltd. that provides rights to Eiken’s loop-mediated isothermal amplification technology. This license

provides us with rights for infectious disease testing in the United States and 18 other geographic markets. We currently have one product in active development using this molecular technology. Several other infectious diseases have been identified for future development using this technology.

Manufacturing

Our immunodiagnostic products require the production of highly specific and sensitive antigens and antibodies. Meridian produces substantially all of its own requirements including monoclonal antibodies and polyclonal antibodies, plus a variety of fungal, bacterial, and viral antigens. We believe that we have sufficient manufacturing capacity for anticipated growth in the near term.

Intellectual Property, Patents, and Licenses

We own or license US and foreign patents for approximately 25 products manufactured by our US Diagnostics operating segment, including Premierä Platinum HpSA and Premierä Platinum HpSA Plus. In the absence of patent protection, we may be vulnerable to competitors who successfully replicate our production and manufacturing technologies and processes. Our employees are required to execute confidentiality and non-disclosure agreements designed to protect our proprietary products.

Government Regulation

Our diagnostic products are regulated by the Food & Drug Administration (FDA) as “devices” pursuant to the Federal Food, Drug, and Cosmetic Act (FDCA). Under the FDCA, medical devices are classified into one of three classes (i.e., Class I, II or III). Class I and II devices are not expressly approved by the FDA, but, instead, are “cleared” for marketing. Class III devices generally must receive “pre-market approval” from the FDA as to safety and effectiveness.

Each of the diagnostic products currently marketed by us in the United States has been cleared by the FDA pursuant to the 510(k) clearance process or is exempt from such requirements. We believe that most, but not all, products under development will be classified as Class I or II medical devices and, in the case of Class II devices, will be eligible for 510(k) clearance.

Sales of our diagnostic products in foreign countries are subject to foreign government regulation, the requirements of which vary substantially from country to country. The time required to obtain approval by a foreign country may be longer or shorter than that required for FDA approval and the requirements may differ.

European Diagnostics Operating Segment

Our European Diagnostics operating segment’s business focuses on the sale and distribution of diagnostic test kits, manufactured both by our US Diagnostics operating segment and by third-party vendors. Approximately 70% of third-party sales for fiscal 2007 for this operating segment were products purchased from our US Diagnostics operating segment. Third-party sales for this operating segment were $23,563,000, $19,828,000 and $17,818,000 for fiscal 2007, 2006 and 2005, respectively, reflecting a three-year compound annual growth rate of 15%. As of September 30, 2007, the European Diagnostics operating segment had 40 employees, including 17 employees in the direct sales force. Our European Diagnostics operating segment’s sales and distribution network consists of direct sales forces in Belgium, France, Holland, and Italy, and independent distributors in other European countries, Africa and the Middle East. The European Diagnostics operating segment maintains a distribution center in Milan, Italy. The primary markets and customers for this operating segment are hospitals and reference laboratories.

The European Diagnostics operating segment’s functional currency is the Euro. The translation of Euros into US dollars is subject to exchange rate fluctuations.

Life Science Operating Segment

Overview

Our Life Science operating segment’s business focuses on the development, manufacture, sale, and distribution of bulk antigens, antibodies, and reagents used by researchers and other diagnostic companies, as well as contract development and manufacturing services under clinical cGMP conditions. Third-party sales for this operating segment were $24,555,000, $22,864,000 and $21,662,000 for fiscal 2007, 2006 and 2005, respectively, reflecting a three-year compound annual growth rate of 15%. As of September 30, 2007, our Life Science operating segment had 106 employees.

Most of the revenue for our Life Science operating segment currently comes from the manufacture, sale and distribution of bulk antigens, antibodies, and reagents used by researchers and other diagnostic companies. During fiscal 2007, 27% of third-party sales for this segment were to one customer, a substantial portion of which is under exclusive supply agreements that have annual automatic renewal provisions. We have a long-standing relationship with this customer, and although there can be no assurances, we intend to renew these supply agreements in the normal course of business.

Our clinical cGMP protein production facility in Memphis, Tennessee serves as an enabling technology for process development and large-scale manufacturing for biologicals used in new drugs and vaccines. The size of the facility is intended to accommodate manufacturing requirements for Phase I and Phase II clinical trials.

The customer base for this aspect of our Life Science business includes biopharmaceutical and biotechnology companies, as well as government agencies, such as the National Institutes of Health. Revenues for our Life Science operating segment, in the normal course of business, may be affected from quarter to quarter by the timing and nature of arrangements for contract services work, which may have longer production cycles than bioresearch reagents and bulk antigens and antibodies, as well as buying patterns of major customers. See Note 1(j) to the Consolidated Financial Statements herein for revenue recognition policies. Our revenues for contract services were $765,000, $2,537,000, and $3,053,000 in fiscal 2007, 2006, and 2005, respectively.

Products, Markets and Growth Strategies

Our Life Science operating segment’s businesses have been assembled via acquisitions (BIODESIGN International in fiscal 1999, Viral Antigens in fiscal 2000, and most recently, OEM Concepts in fiscal 2005). Historically, these businesses were run autonomously. Over the last 18 months, growth strategies have been developed around sales and marketing integration, new product development integration, and four product brands. Our Life Science operating segment’s four product brands can be described as follows:

	•		BIODESIGN – Antibodies, antigens and assay development reagents
	•		Viral Antigens – Custom infectious disease antigens
	•		OEM Concepts – Custom antibody development and manufacturing, in vivo or in vitro
	•		Meridian Biologics – Development and manufacturing of cGMP clinical grade biologicals

We believe that the business and growth prospects for all four product brands are favorable. Products from the BIODESIGN, OEM Concepts, and Viral Antigens brands are marketed primarily to diagnostic manufacturing customers as a source of raw materials for their products, or as an outsourced step in their manufacturing processes. These markets are highly fragmented; however, we believe we can be successful through product and marketing integration and customer penetration across these three brands. These three brand names were aligned with the predecessor company names, prior to acquisition, as we believe that there is value in the names of these long-standing businesses. Sales efforts are focused on multi-year supply agreements in order to provide stability in volumes and pricing. We believe this benefits both us and our customers.

With respect to our Meridian Biologics brand and contract services, we believe that the business prospects are also favorable despite our recent revenue trends for this brand. In August 2007, we were awarded a five-year contract (base year plus four option years) having a sales value of up to $12,200,000 for the manufacturing of experimental clinical vaccines for the National Institutes of Allergy and Infectious Diseases of the National Institutes of Health. This contract provides an opportunity for steady production work over a five-year period.

Research and Development

Our Life Science operating segment’s research and development organization consists of 5 research scientists. Research and development expenses for our Life Science operating segment for fiscal 2007, 2006 and 2005 were $1,514,000, $1,457,000 and $823,000, respectively. This research and development organization has integrated its activities around the four product brands previously discussed.

Manufacturing and Government Regulation

The cGMP clinical grade proteins that are produced in our Memphis facility are intended to be used as “injectables”. As such, they are produced under cGMP Regulations for Biologics and Human Drugs under the auspices of the FDA. Approval and licensing, following clinical trials, of these products is the responsibility of the applicant, who owns the rights to each protein. Typically, the customer is the applicant, not Meridian Life Science.

All of the Meridian Life Science facilities are ISO 9001:2000 certified and EC 1774:2002 approved.

Competition

Diagnostics

The market for diagnostic tests is a multi-billion dollar international industry, which is highly competitive. Many of our competitors are larger with greater financial, research, manufacturing and marketing resources. Important competitive factors of Meridian’s products include product quality, price, ease of use, customer service, and reputation. In a broader sense, industry competition is based upon scientific and technological capability, proprietary know-how, access to adequate capital, the ability to develop and market products and processes, the ability to attract and retain qualified personnel and the availability of patent protection. To the extent that our product lines do not reflect technological advances, our ability to compete in those product lines could be adversely affected.

The diagnostic test industry is highly fragmented and segmented. Of importance in the industry are mid-sized medical diagnostic specialty companies, like Meridian, that offer multiple, broad product lines and have the ability to deliver new, high value products quickly to the marketplace. Among the companies with which we compete in the marketing of one or more of our products are Abbott Laboratories Inc., Becton, Dickinson and Company, Diagnostic Products Corporation (acquired by Siemens in 2006), Quidel Corporation, Inverness Medical, and Remel (owned by Thermo Fisher).

Life Science

The market for bulk biomedical reagents is highly competitive. Important competitive factors include product quality, price, customer service, and reputation. We face competitors, many of which have greater financial, research and development, sales and marketing, and manufacturing resources where sole-source supply arrangements do not exist. From time to time, customers may choose to manufacture their biomedical reagents in-house rather than purchase from outside vendors such as Meridian.

The market for contract manufacturing in a validated cGMP facility such as our Memphis facility is also competitive. Important competitive factors include reputation, customer service, and price. Although the product application for this facility was built from our existing expertise in cell culture manufacturing techniques, we face competitors with greater experience in contract manufacturing in a clinical cGMP environment.

Acquisitions

Acquisitions have played an important role in the historical growth of our businesses. Our acquisition objectives include, among other things, (i) enhancing product offerings, (ii) improving product distribution capabilities, (iii) providing access to new markets, and/or (iv) providing access to key biologicals or new technologies that lead to new products. Although we cannot provide any assurance that we will consummate any acquisitions in the future, we expect that the potential for acquisitions will continue to serve as an opportunity for new revenues and earnings growth in the future.

International Markets

International markets are an important source of revenue and future growth opportunities for all of our operating segments. For all operating segments combined, international sales were $38,691,000 or 31% of total fiscal 2007 sales, $34,557,000 or 32% of total fiscal 2006 sales and $30,232,000 or 33% of total fiscal 2005 sales. Domestic exports for our US Diagnostics and Life Science operating segments were $15,128,000, $14,728,000 and $12,414,000 in fiscal 2007, 2006 and 2005, respectively. We expect to continue to look to international markets as a source of new revenues and growth in the future.

Environmental

We are a conditionally exempt small quantity generator of hazardous waste and have a US EPA identification number. All hazardous material is manifested and disposed of properly. We are in compliance with applicable portions of the federal and state hazardous waste regulations and have never been a party to any environmental proceeding.

ITEM 1A.

RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the following factors which could materially affect our business, financial condition, cash flows or future results. Any one of these factors could cause our actual results to vary materially from recent results or from anticipated future results. The risks described below are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Risks Affecting Growth and Profitability of our Business

We may be unable to develop new products and services or acquire products and services on favorable terms.

The medical diagnostic and life science industries are characterized by ongoing technological developments and changing customer requirements. As such, our results of operations and continued growth depend, in part, on our ability in a timely manner to develop or acquire rights to, and successfully introduce into the marketplace, enhancements of existing products and services or new products and services that incorporate technological advances, meet customer requirements, and respond to products developed by our competition. We cannot provide any assurance that we will be successful in developing or acquiring such rights to products and services on a timely basis, or that such products and services will adequately address the changing needs of the marketplace, either of which could adversely affect our results of operations.

In addition, we must regularly allocate considerable resources to research and development of new products, services, and technologies. The research and development process generally takes a significant amount of time from design stage to product launch. This process is conducted in various stages. During each stage, there is a risk that we will not achieve our goals on a timely basis, or at all, and we may have to abandon a product in which we have invested substantial resources.

During 2007, 2006, and 2005, we incurred $6,085,000, $4,799,000, and $3,866,000, respectively, in research and development expenses. We expect to continue to invest in our research and development activities.

We may be unable to successfully integrate operations or to achieve expected cost savings from acquisitions we make.

One of our main growth strategies is the acquisition of companies and/or products. Although additional acquisitions of companies and products may enhance the opportunity to increase net earnings over time, such acquisitions could result in greater administrative burdens, increased exposure to the uncertainties inherent in marketing new products, and financial risks of additional operating costs. The principal benefits expected to result from any acquisitions we make will not be achieved fully unless we are able to successfully integrate the

operations of the acquired entities with our operations and realize the anticipated synergies, cost savings, and growth opportunities from integrating these businesses into our existing businesses. We cannot provide any assurance that we will be able to identify and complete additional acquisitions on terms we consider favorable or that, if completed, will be successfully integrated into our operations.

Revenues for our diagnostic operating segments may be impacted by our reliance upon two key distributors, seasonal factors and sporadic outbreaks, and changing diagnostic market conditions.

Key Distributors

Our US Diagnostic operating segment’s sales through two distributors were 51% and 47%, respectively, of the US Diagnostics operating segment’s total sales for fiscal 2007 and fiscal 2006, or 31% and 29%, respectively, of consolidated total sales for fiscal 2007 and fiscal 2006. These parties distribute our products and other laboratory products to end-user customers. The loss of either of these distributors could negatively impact our sales and results of operations unless suitable alternatives were timely found or lost sales to one distributor were absorbed by another distributor. Finding a suitable alternative on satisfactory terms may pose challenges in our industry’s competitive environment.

As an alternative, we could expand our efforts to distribute and market our products directly. This alternative, however, would require substantial investment in additional sales, marketing, and logistics resources, including hiring additional sales and customer service personnel, which would significantly increase our future selling, general, and administrative expenses.

Seasonal Factors and Sporadic Outbreaks

Our principal business is the sale of a broad range of diagnostic test kits for common respiratory, gastrointestinal, viral, and parasitic infectious diseases. Certain infectious diseases may be seasonal in nature, while others may be associated with sporadic outbreaks, such as food-borne illnesses. While we believe that the breadth of our diagnostic product lines reduces the risk that infections subject to seasonality and sporadic outbreaks will cause variability in diagnostic revenues, we can make no assurance that revenues will not be negatively impacted period over period by such factors.

Changing Diagnostic Market Conditions

Changes in the healthcare delivery system have resulted in major consolidation among reference laboratories and in the formation of multi-hospital alliances, reducing the number of institutional customers for diagnostic test products. Due to such consolidation, we may not be able to enter into and/or sustain contractual or other marketing or distribution arrangements on a satisfactory commercial basis with institutional customers, which could adversely affect our results of operations.

Third party payers for medical products and services, including state and federal governments, are increasingly concerned about escalating health care costs and can indirectly affect the pricing or the relative attractiveness

of our products by regulating the maximum amount of reimbursement they will provide for diagnostic testing services. If reimbursement amounts for diagnostic testing services are decreased in the future, such decreases may reduce the amount that will be reimbursed to hospitals or physicians for such services and consequently could place constraints on the levels of overall pricing, which could have a material effect on our sales and/or profit margins.

Revenues for our Life Science operating segment may be impacted by customer concentrations and buying patterns.

Our Life Science operating segment’s sales of purified antigens and reagents to one customer were 27% and 18%, respectively, of the Life Science operating segment’s total sales for fiscal 2007 and fiscal 2006, or 5% and 4%, respectively, of our consolidated total sales for fiscal 2007 and fiscal 2006. A substantial portion of these sales are under exclusive supply agreements that have annual automatic renewal provisions. Although we have a long-standing relationship with this customer, we cannot provide any assurance that we will be able to renew these supply agreements, which could adversely affect our sales and results of operations.

Our Life Science operating segment has five other significant customers who purchase antigens, antibodies and reagents, which together comprised 19% and 20%, respectively, of the operating segment’s total sales for fiscal 2007 and fiscal 2006. Any significant alteration of buying patterns from these customers could adversely affect our period over period sales and results of operations.

Revenues relating to research, development and manufacturing services for our Life Science operating segment are generated on a contract by contract basis. The nature of this business is such that each contract provides a unique product and/or service and corresponding revenue stream. Although we believe that future prospects for this business will generate targeted growth rates, there can be no assurance that future contracts will be secured, and if secured, will be profitable.

Intense competition could adversely affect our profitability.

The markets for our products and services are characterized by substantial competition and rapid change. Hundreds of companies in the United States supply immunodiagnostic tests and purified reagents. These companies range from multinational healthcare entities, for which immunodiagnostics is one line of business, to small start-up companies. Many of our competitors have significantly greater financial, technical, manufacturing, and marketing resources than we do. We cannot provide any assurance that our products and services will be able to compete successfully with the products and services of our competitors.

We are dependent on international sales, and our financial results may be adversely impacted by foreign currency, regulatory or other developments affecting international markets.

We sell products and services into approximately 60 countries. Approximately 31% of our net sales for fiscal 2007 and approximately 32% of our net sales for fiscal 2006 were attributable to international markets. For fiscal 2007, 52% of our international sales were made in Euros, with the remaining 48% made in U.S. dollars. We are subject to the risks associated with fluctuations in the U.S. dollar-Euro exchange rates. We are also subject to other risks associated with international operations, including longer customer payment cycles, tariff regulations, requirements for export licenses, stability of foreign governments, and governmental requirements with respect to the importation and distribution of medical devices and antigens, antibodies and reagents, all of which may vary by country.

Risks Affecting our Manufacturing Operations

We are subject to comprehensive regulation, and our ability to earn profits may be restricted by these regulations.

Medical device diagnostics and the manufacture, sale, and distribution of bulk antigens, antibodies, and reagents are highly regulated industries. We cannot provide any assurance that we will be able to obtain necessary governmental clearances or approvals or timely clearances or approvals to market future products in the United States and other countries. Costs and difficulties in complying with laws and regulations administered by the U.S. Food and Drug Administration, the U.S. Department of Agriculture, the U.S. Department of Commerce, the U.S. Drug Enforcement Agency, or the Centers for Disease Control can result in unanticipated expenses and delays and interruptions to the sale of new and existing products. Contract manufacturing of proteins and other biologicals is regulated by the U.S. Food and Drug Administration.

Regulatory approval can be a lengthy, expensive, and uncertain process, making the timing and costs of approvals difficult to predict. The failure to comply with these regulations can result in delay in obtaining authorization to sell products, seizure or recall of products, suspension or revocation of authority to manufacture or sell products, and other civil or criminal sanctions.

Significant interruptions in production at our principal manufacturing facilities and/or third-party manufacturing facilities would adversely affect our business and operating results.

Products and services manufactured at our Cincinnati, Ohio, Boca Raton, Florida, Memphis, Tennessee, and Saco, Maine facilities comprise 81% of our diagnostics revenues and 78% of our Life Science revenues. Our global supply of these products and services is dependent on the uninterrupted and efficient operation of these facilities. In addition, we currently rely on a small number of third-party manufacturers to produce certain of our diagnostic products. The operations of our facilities or these third-party manufacturing facilities could be adversely affected by power failures, natural or other disasters, such as earthquakes, floods, or terrorist threats.

Although we carry insurance to protect against certain business interruptions at our facilities, there can be no assurance that such coverage will be adequate or that such coverage will continue to remain available on acceptable terms, if at all. Any significant interruption in the Company’s or third-party manufacturing capabilities could materially and adversely affect our operating results.

We are dependent on sole-source suppliers for certain critical components and products. A supply interruption could adversely affect our business.

Our products are made from a wide variety of raw materials that are generally available from alternate sources of supply. However, certain critical raw materials and supplies required for the production of some of our principal products are available only from a single supplier. In addition, certain finished products, for which we act as a distributor, are available only from a single supplier. If these suppliers become unable or unwilling to supply the required raw materials or products, we would need to find another source, and perform additional development work and obtain regulatory approvals for the use of the alternative raw materials for our products. Completing that development and obtaining such approvals could require significant time and resources, and may not occur at all. Any disruption in the supply of these raw materials or finished products could have a material adverse affect on us.

Risks Related to Intellectual Property and Product Liability

We may be unable to protect or obtain proprietary rights that we utilize or intend to utilize.

In developing and manufacturing our products, we employ a variety of proprietary and patented technologies. In addition, we have licensed, and expect to continue to license, various complementary technologies and methods from academic institutions and public and private companies. We cannot provide any assurance that the technologies that we own or license provide protection from competitive threats or from challenges to our intellectual property. In addition, we cannot provide any assurances that we will be successful in obtaining licenses or proprietary or patented technologies in the future.

Product infringement claims by other companies could result in costly disputes and could limit our ability to sell our products.

Litigation over intellectual property rights is prevalent in the diagnostic industry. As the market for diagnostics continues to grow and the number of participants in the market increases, we may increasingly be subject to patent infringement claims. It is possible that a third-party may claim infringement against us. If found to infringe, we may attempt to obtain a license to such intellectual property, however, we may be unable to do so on favorable terms, or at all. Additionally, if our products are found to infringe on a third party’s intellectual property, we may be required to pay damages for past infringement and lose the ability to sell certain products, causing our revenues to decrease.

If product liability lawsuits are successfully brought against us, we may incur substantial liabilities and may have to limit or cease sales of our products.

The testing, manufacturing, and marketing of medical diagnostic products involves an inherent risk of product liability claims. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit or cease sales of our products. We currently carry product liability insurance at a level we believe is commercially reasonable, although there is no assurance that it will be adequate to cover claims that may arise. In certain customer contracts, we indemnify third parties for certain product liability claims related to our products. These indemnification obligations may cause us to pay significant sums of money for claims that are covered by these indemnifications. In addition, a defect in the design or manufacture of our products could have a material adverse affect on our reputation in the industry and subject us to claims of liability for injury and otherwise. Any substantial underinsured loss resulting from such a claim could have a material adverse affect on our profitability and the damage to our reputation in the industry could have a material adverse affect on our business.

Other Risks Affecting Our Business

Our business could be negatively affected if we are unable to attract, hire, and retain key personnel.

Our future success depends on our continued ability to attract, hire, and retain highly qualified personnel, including our executive officers and scientific, technical, sales, and marketing employees, and their ability to manage growth successfully. If such key employees were to leave and we were unable to obtain adequate replacements, our operating results could be adversely affected.

Our bank credit agreement imposes restrictions with respect to our operations.

Our bank credit agreement contains a number of financial covenants that require us to meet certain financial ratios and tests. If we fail to comply with the obligations in the credit agreement, we would be in default under the credit agreement. If an event of default is not cured or waived, it could result in acceleration of any indebtedness under our credit agreement, which could have a material adverse effect on our business. At the present time, no borrowings are outstanding under our bank credit agreement.

Risks Related to Our Common Stock

Our board of directors has the authority to issue up to 1,000,000 shares of undesignated preferred stock and to determine the rights, preferences, privileges and restrictions, including voting rights, of such shares without any future vote or action by the shareholders. The issuance of preferred stock under certain circumstances could have the effect of delaying or preventing a change in control of our company. Ohio corporation law contains provisions that may discourage takeover bids for our company that have not been negotiated with the board of directors. Such provisions could limit the price that investors might be willing to pay in the future for shares of our common stock. In addition, sales of substantial amounts of such shares in the public market could

adversely affect the market price of our common stock and our ability to raise additional capital at a price favorable to us.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

Refer to “Forward Looking Statements” following the Index in front of this Form 10-K and Item 1A “Risk Factors on pages 12 through 19 of this Annual Report.

Overview:

For fiscal 2007, we delivered our fifth consecutive year of double-digit sales and earnings growth. Our diagnostics operating segments continue to provide the largest share of consolidated revenues, 80%, for fiscal 2007 compared to 79% for fiscal 2006. Our Life Science operating segment’s sales performance improved quarter-by-quarter throughout fiscal 2007, with double-digit increases in the third and fourth quarters. We are encouraged by this momentum as we enter fiscal 2008.

Our sales growth in fiscal 2007 was organic and driven by new diagnostic products launched in the past three years, market expansions, increased market share in targeted disease states, and volume increases for antibodies, antigens and reagents supplied to large diagnostic manufacturing companies. Our newest diagnostic product contributing to growth is ImmunoCard STAT!^® EHEC, a rapid test developed in collaboration with Merck for detection of toxin-producing E. coli in patients that may have ingested contaminated produce or meat products. We continue to see growth in the C. difficile testing market where we hold a market leadership position. This market has expanded as testing increases due to more virulent strains of this toxin and heightened focus by hospitals on this dangerous pathogen. We have been well positioned with our broad line of C. difficile products, including our newest in the portfolio, ImmunoCard^® Toxins A&B. Our upper respiratory line of products also saw growth, as did our H. pylori line of products. New AGA guidelines are creating increased focus on direct antigen testing for this infection that causes ulcers. Our line of patented H. pylori products includes both rapid and batch method noninvasive direct testing formats. We are seeing growth as more laboratories switch from serology based antibody testing to direct antigen testing. Finally, our Life Science operating segment has seen volume demand for antibodies, antigens, and other reagents increase with large diagnostic manufacturing companies.

Financial discipline is also one of our fundamental principles in running the day-to-day business. The following table illustrates key income and expense elements as a percentage of sales. We look for continued improvement in each of these measures each year.

		2007				2006				2005
Gross profit			61	%			60	%			59	%
Operating expenses			32	%			35	%			37	%
Operating income			28	%			25	%			22	%

Operating Segments:

Meridian’s reportable operating segments are US Diagnostics, European Diagnostics, and Life Science. The US Diagnostics operating segment consists of manufacturing operations in Cincinnati, Ohio, and the sale and distribution of diagnostic test kits in the US and countries outside of Europe, Africa and the Middle East. The European Diagnostics operating segment consists of the sale and distribution of diagnostic test kits in Europe, Africa and the Middle East. The Life Science operating segment consists of manufacturing operations in Memphis, Tennessee, Saco, Maine, and Boca Raton, Florida, and the sale and distribution of bulk antigens, antibodies, and bioresearch reagents domestically and abroad. The Life Science operating segment also includes the contract development and manufacture of proteins and other biologicals for use by biopharmaceutical and biotechnology companies engaged in research for new drugs and vaccines.

Revenues for the Diagnostics operating segments, in the normal course of business, may be affected from quarter to quarter by buying patterns of major distributors, seasonality and strength of certain diseases and foreign currency exchange rates. Revenues for the Life Science operating segment, in the normal course of business, may be affected from quarter to quarter by the timing and nature of arrangements for contract services work, which may have longer production cycles than bioresearch reagents and bulk antigens and antibodies, as well as buying patterns of major customers. Meridian believes that the overall breadth of its product lines serves to reduce the variability in consolidated sales from quarter to quarter.

Results of Operations:

Overview

Fourth quarter

Net earnings for the fourth quarter of fiscal 2007 increased 36% to $6,444,000, or $0.16 per diluted share (increased 33%) from net earnings for the fourth quarter of fiscal 2006 of $4,730,000, or $0.12 per diluted share. This increase is primarily attributable to increased sales and continuing efforts to improve operating efficiency across all businesses. Net sales for the fourth quarter of fiscal 2007 were $32,386,000, an increase of $3,736,000 or 13% compared to the fourth quarter of fiscal 2006.

During the fourth quarter of fiscal 2006, Meridian determined that the carrying value of a supply contract with the United States Department of Defense related to the Life Science operating segment had become impaired and recorded such impairment to general and administrative expenses in the amount of $826,000. The contract provided for the supply of biological materials during a base period and also contained four optional 12-month renewal periods through March 31, 2009. Changes in the Department’s Critical Reagents Program lowered the amount of materials to be supplied under the contract. During March 2007, the Department informed Meridian

that it would not be exercising the optional renewal period from April 1, 2007 through March 31, 2008. Meridian does not expect to supply any more materials under this contract, and as of September 30, 2007, this contract had no carrying value.

Prior to July 1, 2007, the cost of certain inventories within the Life Science operating segment was determined by the last-in, first-out (“LIFO”) method. Effective July 1, 2007, we changed our method of accounting for this inventory from the LIFO method to the FIFO method, and now substantially all of our inventories are reflected at the lower of cost or market with cost determined by the FIFO method. We changed to the FIFO method for these inventories because it conforms substantially all of our worldwide inventories to a consistent basis of accounting; and it provides better comparability to our industry peers, many of whom use the FIFO method of accounting for inventories. In accordance with Statement of Financial Accounting Standards (“SFAS”) No. 154, Accounting Changes and Error Corrections, the change in accounting has been retrospectively applied to all prior periods presented herein. See Note 1(g) to the consolidated financial statements contained herein.

Fiscal Year

Net earnings for fiscal 2007 increased 46% to $26,721,000, or $0.66 per diluted share (increased 43%) from net earnings for fiscal 2006 of $18,333,000, or $0.46 per diluted share. Results of operations for fiscal 2007 compared to fiscal 2006 are discussed below.

Net earnings and earnings per share for fiscal 2007 include the effects of a tax benefit in the amount of $2,425,000, or $0.06 per basic and diluted share, related to a discrete adjustment to tax reserves that was recorded in the third quarter upon the expiration of the statute of limitations on certain income tax returns (see Note 7 to the consolidated financial statements herein). The tables below provide information on net earnings, basic earnings per share, and diluted earnings per share, excluding this tax benefit, as well as reconciliations to amounts reported under US Generally Accepted Accounting Principles. We believe that this information is useful to those who read our financial statements and evaluate our operating results because:

1. These measures help to appropriately evaluate and compare the results of operations from period to period by removing the favorable impact of a discrete material item that is not expected to recur in the future; and

2. These measures are used by our management for various purposes, including evaluating performance against incentive bonus achievement targets, comparing performance from period to period in presentations to our Board of Directors, and as a basis for strategic planning and forecasting.

Fiscal Year Ended September 30, 2007 Compared to Fiscal Year Ended September 30, 2006

Net sales

Overall, net sales increased 13% for fiscal 2007 compared to fiscal 2006. Net sales for the US Diagnostics operating segment increased $9,124,000, or 14%, for the European Diagnostics operating segment increased $3,735,000, or 19%, and for the Life Science operating segment increased $1,691,000, or 7%.

For the US Diagnostics operating segment, 45% of the sales increase was related to growth in C. difficile products (increased $4,099,000), reflecting volume increases for ImmunoCard^® Toxins A & B and Premier^TM Toxins A & B. Sales of respiratory products (increased $1,432,000) also contributed to the increase, driven by increased market share and increased purchases by one national distributor. Meridian’s respiratory products include diagnostic tests for influenza, Respiratory Syncytial Virus (RSV), and Mycoplasma. H. pylori sales (increased $1,625,000) contributed to the increase due to increased managed care efforts, issuance of AGA guidelines recommending direct testing, and increased marketing of Premier^TM Platinum HpSA PLUS. Volume increases for parasitology products (increased $1,063,000) related to the exit of a competitor from the marketplace, food borne products (increased $1,603,000) related to the 2007 launch of ImmunoCard STAT!^® EHEC, and volume increases in specimen transport products ($501,000) also contributed to favorable variances to fiscal 2006. These favorable variances more than offset an unfavorable variance of $809,000 for microbiology products related to reduced purchases of one product by one international customer. Two national distributors accounted for 51% and 47% of total sales for the US Diagnostics operating segment for fiscal 2007 and 2006, respectively.

For the European Diagnostics operating segment, the sales increase includes currency translation gains in the amount of $1,769,000. Sales in local currency, the Euro, increased 10%. The local currency increase was driven by C. difficile products ($1,559,000), including ImmunoCard^Ò Toxins A & B.

For the Life Science operating segment, the sales increase was primarily attributable to buying patterns and volume growth in make-to-order bulk antigens and antibodies, offset by lower sales activity from contract research and development and contract manufacturing services. Sales of made-to-order bulk antigens and antibodies to one customer accounted for 27% and 18% of total sales for the Life Science Operating segment for fiscal 2007 and 2006, respectively.

For all operating segments combined, international sales were $38,691,000, or 31% of total sales, for fiscal 2007, compared to $34,557,000, or 32% of total sales, in fiscal 2006. Combined domestic exports for the US Diagnostics and Life Science operating segments were $15,128,000 for fiscal 2007, compared to $14,728,000 in fiscal 2006. The remaining international sales were generated by the European Diagnostics operating segment.

Gross Profit

Gross profit increased 16% for fiscal 2007 compared to fiscal 2006. Gross profit margins were 61% for fiscal 2007 compared to 60% for fiscal 2006. This increase reflects higher margins commanded by volume increases in rapid tests, such as ImmunoCard^® Toxins A & B and operating efficiencies. We have also seen improvements in gross profit margins related to automation initiatives and related efficiencies in diagnostic production areas.

Our overall operations consist of the sale of diagnostic test kits for various disease states and in alternative test formats, as well as bioresearch reagents, bulk antigens and antibodies, proficiency panels, and contract research and development and contract manufacturing services. Product sales mix shifts, in the normal course of business, can cause the consolidated gross profit margin to fluctuate by several points.

Operating Expenses

Operating expenses increased 6% for fiscal 2007 compared to fiscal 2006. The overall increase in operating expenses for fiscal 2007 is discussed below.

Research and development expenses increased 27% for fiscal 2007 compared to fiscal 2006, and as a percentage of sales, were 5% in fiscal 2007 compared to 4% in fiscal 2006. Of this increase, $1,229,000 related to the US Diagnostics operating segment and $57,000 related to the Life Science operating segment. The increase for the US Diagnostics operating segment was primarily attributable to clinical trial and other costs associated with new product development, including planned headcount additions, as well as increased stock compensation expense.

Selling and marketing expenses increased 3%, for fiscal 2007 compared to fiscal 2006, and as a percentage of sales, decreased to 14% for fiscal 2007 from 15% for fiscal 2006. Of this increase, $469,000 related to the European Diagnostics operating segment, offset by decreases of $34,000 related to the Life Science operating segment and $9,000 for the US Diagnostics operating segment. The increase for the European Diagnostics operating segment was primarily attributable to fluctuations in the Euro currency and one planned headcount addition. The decrease for the US Diagnostics operating segment was primarily attributable to lower costs for sales promotions, advertising and distributor incentives, offset by increased salaries and benefits related to headcount additions and stock based compensation costs.

General and administrative expenses increased 3%, for fiscal 2007 compared to fiscal 2006, and as a percentage of sales, decreased from 15% in fiscal 2006 to 14% in fiscal 2007. Of this increase, $1,523,000 related to the US Diagnostics operating segment, offset by decreases of $806,000 related to the Life Science operating segment and $309,000 related to the European Diagnostics operating segment. The increase for the US Diagnostics operating segment was primarily attributable to higher costs for stock-based compensation, an insurance recovery in fiscal 2006, and increased salaries and benefits, including the effects of planned headcount additions. The decrease for the Life Science operating segment was primarily attributable to the 2006 impairment of the supply contract with the United States Department of Defense. See Note 1(i) to the consolidated financial statements contained herein. The decrease for the European Diagnostics operating segment was primarily attributable to expenses connected with an employee matter in fiscal 2006, which were covered by the aforementioned insurance recovery.

Effective July 1, 2005, Meridian adopted the provisions of SFAS No. 123(R), Share-Based Payment, in accounting for its stock option plans. The amount of stock-based compensation expense reported for fiscal 2007, fiscal 2006, and fiscal 2005 was $2,632,000, $1,082,000, and $279,000, respectively.

During November 2006, Meridian granted to certain employees, 293,250 stock options that were contingent upon Meridian achieving a specified income level for fiscal 2007. Meridian’s fiscal 2007 net income surpassed the minimum level, and thus, these stock options were earned and are now exercisable over a vesting period. Fiscal 2007 stock-based compensation cost for these stock options, in accordance with SFAS No. 123(R), was approximately $973,000 and was recorded in the fourth quarter.

Operating Income

Operating income increased 30% in fiscal 2007, as a result of the factors discussed above.

Other Income and Expense

Interest income was $1,642,000 for fiscal 2007, compared to $1,123,000 for fiscal 2006. This increase was driven

by higher interest yields and higher investment balances in fiscal 2007.

Interest expense declined 70% for fiscal 2007 compared to fiscal 2006. This decrease was attributable to the positive effects of the debenture conversion and redemption transactions discussed under Liquidity and Capital Resources herein. As of September 30, 2007, there were no debentures outstanding.

Income Taxes

The effective rate for income taxes was 27% for fiscal 2007 and 35% for fiscal 2006. The decrease in the effective tax rate was primarily attributable to a discrete adjustment to tax reserves in the third quarter in the amount of $2,425,000. This discrete adjustment reduced the effective tax rate by 7 points. See Note 7 to the consolidated financial statements included herein for a complete discussion of this matter.

Fiscal Year Ended September 30, 2006 Compared to Fiscal Year Ended September 30, 2005

Net sales

Overall, net sales increased 17% for fiscal 2006 compared to fiscal 2005. Net sales for the US Diagnostics operating segment increased $12,236,000, or 23%, for the European Diagnostics operating segment increased $2,010,000, or 11%, and for the Life Science operating segment increased $1,202,000, or 6%.

For the US Diagnostics operating segment, 46% of the sales increase was related to growth in C. difficile products (increased $5,682,000), reflecting the market expansion and gains in market share related to the 2005 launch of ImmunoCard^Ò Toxins A & B. Sales of respiratory products (increased $1,819,000) also contributed to the increase, driven by growth in international markets and favorable changes in insurance reimbursement policies. Meridian’s respiratory products include diagnostic tests for influenza, Respiratory Syncytial Virus (RSV), and mycoplasma. H. pylori sales (increased $996,000) contributed to the increase due to increased testing and positive results from focused marketing efforts on the managed care sector. Sales increases for parasitology products (increased $1,019,000), fungal products (increased $860,000), food borne products (increased $632,000), rotavirus products (increased $565,000) and microbiology products ($480,000) also contributed to favorable variances to fiscal 2005.

For the European Diagnostics operating segment, the sales increase offsets currency translation losses in the amount of approximately $662,000. Sales in local currency, the Euro, increased 15%. The local currency increase was driven by market increases in sales of H. pylori products ($1,182,000). Increases in sales of C. difficile products ($901,000), including ImmunoCard^Ò Toxins A & B, also contributed to the increase.

For the Life Science operating segment, the sales increase was primarily attributable to the inclusion of OEM Concepts for a full year in fiscal 2006, compared to eight months in fiscal 2005. This was partially offset by

shifts in buying patterns by one large diagnostic manufacturing customer and one large defense customer, as well as the timing and number of contract services arrangements. Sales of made-to-order bulk antigens and antibodies to one customer accounted for 18% and 23% of total sales for the Life Science Operating segment for fiscal 2006 and 2005, respectively.

For all operating segments combined, international sales were $34,557,000, or 32% of total sales, for fiscal 2006, compared to $30,232,000, or 33% of total sales, in fiscal 2005. Combined domestic exports for the US Diagnostics and Life Science operating segments were $14,728,000 for fiscal 2006, compared to $12,414,000 in fiscal 2005. The remaining international sales were generated by the European Diagnostics operating segment.

Gross Profit

Gross profit increased 18% for fiscal 2006 compared to fiscal 2005. Gross profit margins were 60% for fiscal 2006 compared to 59% for fiscal 2005. This increase reflects higher margins commanded by new rapid tests, such as ImmunoCard^® Toxins A & B and operating efficiencies.

Meridian’s overall operations consist of the sale of diagnostic test kits for various disease states and in alternative test formats, as well as bioresearch reagents, bulk antigens and antibodies, proficiency panels, and contract research and development and contract manufacturing services. Product sales mix shifts, in the normal course of business, can cause the consolidated gross profit margin to fluctuate by several points.

Operating Expenses

Operating expenses increased 9% for fiscal 2006 compared to fiscal 2005. The overall increase in operating expenses for fiscal 2006 is discussed below.

Research and development expenses increased 24% for fiscal 2006 compared to fiscal 2005, and as a percentage of sales, were 4% in fiscal 2006 and fiscal 2005. Of this increase, $299,000 related to the US Diagnostics operating segment and $634,000 related to the Life Science operating segment. The US Diagnostics operating segment increase was primarily attributable to increased stock compensation expense. For the Life Science operating segment, during fiscal 2005, research and development scientists were performing contract work for third-party customers, and thus, their related costs were classified in cost of sales. During fiscal 2006, their efforts and activities were primarily focused on internal research and development work, and therefore charged to research and development expense, rather than being classified in cost of sales or inventory. The increase for the Life Science operating segment reflects the classification of such costs.

Selling and marketing expenses increased 10%, for fiscal 2006 compared to fiscal 2005, and as a percentage of sales, decreased from 16% for fiscal 2005 to 15% for fiscal 2006. Of this increase, $1,195,000 related to the US Diagnostics operating segment and $475,000 related to the Life Science operating segment, partially offset by a decrease of $180,000 for the European Diagnostics operating segment. The increase for the US Diagnostics operating segment was primarily attributable to sales administration fees to group purchasing organizations and incentive compensation associated with higher sales levels, as well as higher salaries and benefits costs. The increase for the Life Science operating segment was primarily due to business development costs and a full year of costs for the OEM Concepts business, acquired during the second quarter of fiscal 2005. The decrease for the European Diagnostics operating segment was primarily attributable to fluctuations in the Euro currency.

General and administrative expenses increased 5%, for fiscal 2006 compared to fiscal 2005, and as a percentage of sales, decreased from 17% in fiscal 2005 to 15% in fiscal 2006. Of this increase, $18,000 related to the US Diagnostics operating segment, $679,000 related to the Life Science operating segment and $105,000 related to the European Diagnostics operating segment. The increase for the US Diagnostics operating segment was primarily attributable to increased salaries and benefits costs and increased stock compensation expense, offset by an insurance recovery received and decreased legal and professional fees related to efficiencies in reporting under the Sarbanes-Oxley Act. The increase for the Life Science operating segment was primarily attributable to the impairment of a supply contract related to the acquisition of OEM Concepts. See Note 1(i) to the consolidated financial statements contained herein.

Operating Income

Operating income increased 32% in fiscal 2006, as a result of the factors discussed above.

Other Income and Expense

Interest income was $1,123,000 for fiscal 2006, and related primarily to interest earned on proceeds from the September 2005 common share offering that have been primarily invested in tax-exempt securities.

Interest expense declined 83% for fiscal 2006 compared to fiscal 2005. This decrease was attributable to the positive effects of the debenture conversion and redemption transactions discussed under Liquidity and Capital Resources herein.

Income Taxes

The effective rate for income taxes was 35% for fiscal 2006 and 36% for fiscal 2005. The decrease in the effective tax rate was primarily attributable to the favorable effects of tax-exempt interest and domestic production incentives under the American Jobs Creation Act.

Liquidity and Capital Resources:

Comparative Cash Flow Analysis

Our operating cash flow and financing requirements are determined by analyses of operating and capital spending budgets and consideration of acquisition plans. We have historically maintained revolving line of credit availability to respond quickly to acquisition opportunities. This revolving line of credit is supplemented by the proceeds from a September 2005 common share offering, which are invested in tax-exempt, cash-equivalent securities and institutional money-market funds.

Net cash provided by operating activities increased 20% to $26,602,000 in fiscal 2007. This increase was primarily attributable to higher earnings levels. The discrete tax reserve adjustment in the amount of $2,425,000 was non-cash in nature.

Net cash used in investing activities was $443,000 for fiscal 2007, compared to $8,689,000 for fiscal 2006. This decrease was primarily attributable to lower acquisition earnout payments in fiscal 2007 and proceeds from sales of short-term auction rate securities in fiscal 2007 that were purchased in fiscal 2006.

Net cash used in financing activities was $13,291,000 for fiscal 2007, compared to $10,225,000 for fiscal 2006. This increase was primarily attributable to a 43% increase in dividend payments, offset by $914,000 in additional proceeds and tax benefits from the exercise of stock options. Dividend payments in fiscal 2007 reflect increased dividend rates and common shares outstanding related to stock option exercises and bond conversions.

Net cash flows from operating activities are anticipated to fund working capital requirements and dividends during fiscal 2008.

Capital Resources

During August 2007, Meridian completed the renewal of its credit facility with its commercial bank. The amount of the credit facility is $30,000,000, which expires September 15, 2012. As of November 28, 2007, there were no borrowings outstanding under this facility.

As of September 30, 2006, Meridian had outstanding $1,803,000 principal amount of 5% debentures, convertible, at the option of the holder, into common shares at a price of $6.45. During fiscal 2007, these debentures were either converted into common shares at the direction of the holders, or redeemed by Meridian.

The Viral Antigens acquisition, completed in fiscal 2000, provided for additional purchase consideration, contingent upon Viral Antigens’ future earnings through September 30, 2006. Final earnout consideration in the amount of $853,000 relating to fiscal 2006 was paid from operating cash flows during the second quarter of fiscal 2007.

The OEM Concepts acquisition, completed in fiscal 2005, provides for additional purchase consideration up to a maximum remaining amount of $1,819,000, contingent upon future calendar-year sales and gross profit of OEM Concepts products through December 31, 2008. Earnout consideration is payable each year, following the period earned. Earnout consideration in the amount of $118,000 related to calendar 2006 was paid from operating cash flows during the second quarter of fiscal 2007. Earnout consideration in the amount of $152,000 for the first nine months of calendar 2007 is accrued in the accompanying consolidated balance sheet.

Meridian’s capital expenditures are estimated to be approximately $5,000,000 to $6,000,000 for fiscal 2008, and may be funded with cash and equivalents on hand, operating cash flows, and/or availability under the $30,000,000 credit facility discussed above. Capital expenditures relate to manufacturing and other equipment of a normal and recurring nature as well as capacity expansion for the Maine facility.

Other Commitments and Off-balance Sheet Arrangements:

License Agreements

Meridian has entered into various license agreements that require payment of royalties based on a specified percentage of sales of related products (1% to 8%). Meridian expects that payments under these agreements will amount to as much as $447,000 in fiscal 2008. These royalty payments primarily relate to the US Diagnostics operating segment.

During October 2006, Meridian entered into a license agreement with Eiken Chemical Co., Ltd., that provides rights to Eiken’s loop-mediated isothermal amplification technology for infectious disease testing in the United States and 18 other geographic markets. The agreement calls for payments of up to 200,000,000 Japanese Yen (approximately $1,740,000) based on the achievement of certain milestones and on-going royalties once products are available for commercial sale. Payments made during product development are expected to occur

over a five-year period, which began in fiscal 2007. A payment equal to 20,000,000 Japanese Yen was made during fiscal 2007.

During the fourth quarter of fiscal 2007, we began seeking recovery of approximately $1,400,000 of past royalties paid and interest under a license agreement around certain rapid diagnostic testing technology. This license agreement covered patent rights that were narrowed in scope via other litigation with the licensor that did not involve Meridian. We strongly believe that the licensed patent, as reissued, does not cover any of our products. We also ceased further royalty payments under this license agreement. The licensor to this agreement disputes our position that the patent, as reissued, does not cover our products. Although we believe that our position is very strong, we are unable to predict the outcome of this matter. No provision has been made in the accompanying financial statements for on-going royalties, if any, nor has any accrual or income been recorded for recovery of past royalties paid.

Derivative financial instruments

Meridian accounts for its derivative financial instruments in accordance with SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended. These instruments are designated as cash flow hedges, and therefore, the effective portion of the net gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. For the ineffective portion of the hedge, gains or losses are charged to earnings in the current period. All derivative instruments are recognized as either assets or liabilities at fair value in the consolidated balance sheets. See Note 6 to the consolidated financial statements contained herein.

Other

Meridian does not utilize any special-purpose financing vehicles or have any undisclosed off balance sheet arrangements. Similarly, the Company holds no fair-value contracts for which a lack of marketplace quotations would necessitate the use of fair value techniques.

Market Risk Exposure:

Foreign Currency Risk

We have market risk exposure related to foreign currency transactions. Meridian is exposed to foreign currency risk related to its European distribution operations, including foreign currency denominated intercompany sales and receivables. We enter into contractual forward exchange contracts to hedge cash flows from intercompany sales between our US parent company and its Italian affiliate. The counterparties to these

contracts are major financial institutions. Hedging activities are further discussed in Note 6 to the consolidated financial statements.

Concentration of Customers/Products Risk

Our US Diagnostic operating segment’s sales through two distributors were 51% of the US Diagnostics operating segment’s total sales for fiscal 2007 or 31% of consolidated total sales for fiscal 2007. Three internally developed products, Premierä Platinum HpSA PLUS, Premierä Toxins A & B, and ImmunoCard^Ò Toxins A & B, accounted for 39% of our US Diagnostics operating segment’s third-party sales during fiscal 2007. These same three products accounted for 27% of our European Diagnostics operating segment’s third party sales and 31% of our total consolidated sales for fiscal 2007.

Our Life Science operating segment’s sales of purified antigens and reagents to one customer were 27% of the Life Science operating segment’s total sales for fiscal 2007 or 5% of our consolidated total sales for fiscal 2007. Our Life Science operating segment has five other significant customers who purchase antigens, antibodies and reagents, which together comprised 19% of the operating segment’s total sales for fiscal 2007.

Critical Accounting Policies:

The consolidated financial statements included in this Annual Report on Form 10-K have been prepared in accordance with accounting principles generally accepted in the United States. Such accounting principles require management to make judgments about estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. Management believes that the following accounting policies are critical to understanding the accompanying consolidated financial statements because the application of such polices requires the use of significant estimates and assumptions and the carrying values of related assets and liabilities are material.

Revenue Recognition

Our revenues are derived primarily from product sales. Revenue is generally recognized when product is shipped and title has passed to the buyer. Revenue for the US Diagnostics operating segment is reduced at the date of sale for estimated rebates that will be claimed by customers. Rebate agreements are in place with certain independent national distributors and are designed to reimburse such distributors for their cost in handling Meridian’s products. Management estimates rebate accruals based on historical statistics, current trends, and other factors. Changes to these rebate accruals are recorded in the period that they become known.

Life Science revenue for contract services may come from standalone arrangements for process development and/or optimization work (contract research and development services) or custom manufacturing, or multiple-

deliverable arrangements that include process development work followed by larger-scale manufacturing (both contract research and development services and contract manufacturing services). Revenue is recognized based on the nature of the arrangements, using the principles in EITF 00-21, Revenue Arrangements with Multiple Deliverables. The framework in EITF 00-21 is based on each of the multiple deliverables in a given arrangement having distinct and separate fair values. Fair values are determined via consistent pricing between standalone arrangements and multiple deliverable arrangements, as well as a competitive bidding process. Contract research and development services may be performed on a “time and materials” basis or “fixed fee” basis. For “time and materials” arrangements, revenue is recognized as services are performed and billed. For “fixed fee” arrangements, revenue is recognized upon completion and acceptance by the customer. For contract manufacturing services, revenue is recognized upon delivery of product and acceptance by the customer.

Inventories

Our inventories are carried at the lower of cost or market. Cost is determined on a first-in, first-out basis. We establish reserves against cost for excess and obsolete materials, finished goods whose shelf life may expire before sale to customers, and other identified exposures. Such reserves were $1,162,000 and $1,158,000 at September 30, 2007 and 2006, respectively. Management estimates these reserves based on assumptions about future demand and market conditions. If actual demand and market conditions were to be less favorable than such estimates, additional inventory write-downs would be required and recorded in the period known. Such adjustments would negatively affect gross profit margin and overall results of operations.

Intangible Assets

Our intangible assets include identifiable intangibles and goodwill. Identifiable intangibles include customer lists, supply agreements, manufacturing technologies, patents, licenses, and trade names. All of Meridian’s identifiable intangibles have finite lives.

SFAS No. 142, Goodwill and Other Intangible Assets provides that goodwill and intangible assets with indefinite lives are subject to an annual impairment review (or more frequently if impairment indicators arise) by applying a fair-value based test. There have been no impairments from the analyses required by SFAS No. 142.

Identifiable intangibles with finite lives are subject to impairment testing as prescribed by SFAS No. 144, Accounting for the Impairment or Disposal of Long-lived Assets. Pursuant to the provisions of SFAS No. 144, identifiable intangibles with finite lives are reviewed for impairment when events or circumstances indicate that such assets may not be recoverable at their current carrying value. Whether an event or circumstance triggers impairment is determined by comparing an estimate of the asset’s undiscounted future cash flows to its

carrying value. If impairment has occurred, it is measured by a fair-value based test. During fiscal 2006, Meridian determined that the carrying value of a supply contract related to the Life Science operating segment had become impaired and recorded such impairment in the amount of $826,000 to general and administrative expenses. The contract provided for the supply of biological materials to the United States Department of Defense. Changes in the Department’s Critical Reagents Program lowered the amount of materials to be supplied under the contract and ultimately led to the contract having a shorter life than originally expected. There have been no events or circumstances in fiscal 2007 indicating that the carrying value of other such assets may not be recoverable.

Our ability to recover intangible assets, both identifiable intangibles and goodwill, is dependent upon the future cash flows of the related acquired businesses and assets. The application of SFAS Nos. 142 and 144 requires management to make judgments and assumptions regarding future cash flows, including sales levels, gross profit margins, operating expense levels, working capital levels, and capital expenditures. With respect to identifiable intangibles, management also makes judgments and assumptions regarding useful lives.

Management considers the following factors in evaluating events and circumstances for possible impairment: (i) significant under-performance relative to historical or projected operating results, (ii) negative industry trends, (iii) sales levels of specific groups of products (related to specific identifiable intangibles), (iv) changes in overall business strategies and (v) other factors.

If actual cash flows are less favorable than projections, impairment of intangible assets could take place. If impairment were to occur, this would negatively affect overall results of operations.

Income Taxes

Pursuant to SFAS No. 109, Accounting for Income Taxes, our provision for income taxes includes federal, foreign, state, and local income taxes currently payable and those deferred because of temporary differences between income for financial reporting and income for tax purposes. We prepare estimates of permanent and temporary differences between income for financial reporting purposes and income for tax purposes. These differences are adjusted to actual upon filing of our tax returns, typically occurring in the third and fourth quarters of the current fiscal year for the preceding fiscal year’s estimates.

Our deferred tax assets include net operating loss carryforwards in foreign jurisdictions. The realization of tax benefits related to net operating loss carryforwards is dependent upon the generation of future taxable income in the applicable jurisdictions. Management assesses the level of deferred tax asset valuation allowance by taking into consideration historical and future projected operating results, future reversals of taxable temporary differences, as well as tax planning strategies. The amount of net deferred tax assets considered realizable

could be reduced in future years if estimates of future taxable income during the carryforward period are reduced.

Undistributed earnings in our Italian subsidiary are considered by management to be permanently re-invested in such subsidiary. Consequently, US deferred tax liabilities on such earnings have not been recorded. Management believes that such US taxes would be largely offset by foreign tax credits for taxes paid locally in Italy.

From time to time, our tax returns in federal, state, and foreign jurisdictions are examined by the applicable tax authorities. Our tax provisions take into consideration the judgmental nature of certain tax positions through the establishment of reserves for differences between the probable tax determinations and the “as filed” tax positions of certain assets and liabilities. To the extent that adjustments result from the completion of these examinations or the passing of statutes of limitation, they will affect tax liabilities in the period known. We believe that the results of any tax authority examinations would not have a significant adverse impact on financial condition or results of operation.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rule 13a-15(f).

The Company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) 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 (iii) 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 can only provide reasonable assurance and 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 or compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including the Chief Executive Officer and the Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework and criteria in Internal Control – Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on management’s evaluation and those criteria, the Company concluded that its system of internal control over financial reporting was effective as of September 30, 2007.

Report of Independent Registered Public Accounting Firm

Board of Directors and Shareholders of
Meridian Bioscience, Inc.

We have audited the accompanying consolidated balance sheets of Meridian Bioscience, Inc. (an Ohio Corporation) and subsidiaries as of September 30, 2007 and 2006, and the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the three years in the period ended September 30, 2007. We also have audited Meridian Bioscience, Inc.’s internal control over financial reporting as of September 30, 2007, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Meridian Bioscience, Inc.’s management is responsible for these financial statements, 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 these financial statements and an opinion on Meridian Bioscience, Inc.’s internal control over financial reporting 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 audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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, the financial statements referred to above present fairly, in all material respects, the financial position of Meridian Bioscience, Inc. and subsidiaries as of September 30, 2007 and 2006, and the results of their operations and their cash flows for each of the three years in the period ended September 30, 2007 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, Meridian Bioscience, Inc. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of September 30, 2007, based on criteria established in Internal Control—Integrated Framework issued by COSO.

We do not express an opinion or any other form of assurance on Management’s Report on Internal Control over Financial Reporting.

Our audit was conducted for the purpose of forming an opinion on the consolidated financial statements taken as a whole. The accompanying Schedule II is presented for purposes of additional analysis and is not a required part of the basic financial statements. The information for each of the three years in the period ended September 30, 2007 included in this schedule has been subjected to the auditing procedures applied in our audits of the basic financial statements as of September 30, 2007 and 2006 and for each of the three years in the period ended September 30, 2007 and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Meridian Bioscience, Inc. and Subsidiaries

(1) Summary of Significant Accounting Policies

(a)

Nature of Business — Meridian is a fully-integrated life science company whose principal businesses are (i) the development, manufacture and distribution of diagnostic test kits primarily for certain respiratory, gastrointestinal, viral and parasitic infectious diseases, (ii) the manufacture and distribution of bulk antigens, antibodies, and reagents used by researchers and other diagnostic manufacturers and (iii) the contract development and manufacture of proteins and other biologicals for use by biopharmaceutical and biotechnology companies engaged in research for new drugs and vaccines.

(b)

Principles of Consolidation — The consolidated financial statements include the accounts of Meridian Bioscience, Inc. and its subsidiaries. All significant intercompany accounts and transactions have been eliminated. Unless the context requires otherwise, references to “Meridian,” “we,” “us,” “our,” or “our company” refer to Meridian Bioscience, Inc. and its subsidiaries.

(c)

Use of Estimates - The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates are discussed in Notes 1(g), 1(h), 1(i), 1(j), 1(l), 1(m), 7 and 8(b).

(d)

Foreign Currency Translation - Assets and liabilities of foreign operations are translated using year-end exchange rates with gains or losses resulting from translation included in a separate component of accumulated other comprehensive income (loss). Revenues and expenses are translated using exchange rates prevailing during the year. We also recognize foreign currency transaction gains and losses on certain assets and liabilities that are denominated in the Euro currency. These gains and losses are included in other income and expense in the accompanying consolidated statements of operations.

(e)

Cash Equivalents — We consider short-term investments with original maturities of 90 days or less to be cash equivalents, including overnight repurchase agreements, investments in municipal variable rate demand notes that have a seven-day put feature and institutional money market funds.

(f)

Short-term Investments — Auction-rate securities are separately classified as short-term investments in the consolidated financial statements and are accounted for as available-for-sale securities under SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities. As such, unrealized holding gains and losses are reported as a component of other comprehensive income until realized. The carrying value of

these securities was equal to their fair value as of September 30, 2006. We did not hold any auction-rate securities at September 30, 2007. There were no realized gains or losses from the sales of these securities during fiscal 2007.

(g)

Inventories - Inventories are stated at the lower of cost or market. Cost is determined on a first-in, first-out basis (FIFO).

We establish reserves against cost for excess and obsolete materials, finished goods whose shelf life may expire before sale to customers, and other identified exposures. Such reserves were $1,162,000 and $1,158,000 at September 30, 2007 and 2006, respectively. Management estimates these reserves based on assumptions about future demand and market conditions. If actual demand and market conditions were to be less favorable than such estimates, additional inventory write-downs would be required and recorded in the period known. Such adjustments would negatively affect gross profit margin and overall results of operations.

Prior to July 1, 2007, the cost of certain inventories within the Life Science operating segment was determined by the last-in, first-out (“LIFO”) method. Effective July 1, 2007, we changed our method of accounting for this inventory from the LIFO method to the FIFO method, and now substantially all of our inventories are reflected at the lower of cost or market with cost determined by the FIFO method. We changed to the FIFO method for these inventories because: it conforms substantially all of our worldwide inventories to a consistent basis of accounting; and it provides better comparability to our industry peers, many of whom use the FIFO method of accounting for inventories. In accordance with Statement of Financial Accounting Standards (“SFAS”) No. 154, Accounting Changes and Error Corrections, the change in accounting has been retrospectively applied to all prior periods presented herein. The effects of the change as it relates to our consolidated financial statements for the periods presented are as follows:

(h)

Property, Plant and Equipment - Property, plant and equipment are stated at cost. Upon retirement or other disposition of property, plant and equipment, the cost and related accumulated depreciation and amortization are removed from the accounts and the resulting gain or loss is reflected in earnings. Maintenance and repairs are expensed as incurred. Depreciation and amortization are computed on the straight-line method in amounts sufficient to write-off the cost over the estimated useful lives as follows:

Buildings and improvements — 5 to 33 years

Machinery, equipment, and furniture — 3 to 10 years

(i)

Intangible Assets and Application of SFAS Nos. 142 and 144 — SFAS No. 142, Goodwill and Other Intangible Assets, addresses accounting and reporting for acquired goodwill and other intangible assets. SFAS No. 142 provides that goodwill and other intangible assets with indefinite lives are subject to an annual impairment review (or more frequently if impairment indicators arise) by applying a fair-value based test. We perform our annual impairment review as of June 30, the end of our third fiscal quarter. We have no intangible assets with indefinite lives other than goodwill. There have been no impairments from the analyses prepared pursuant to SFAS No. 142. During fiscal 2007, the change in goodwill was an increase of $100,000. This change consisted of an increase related to the OEM Concepts earnout obligations for calendar 2006 and the first nine months of calendar 2007 in the amount of $186,000 (Life Science operating segment), offset by a decrease of $86,000 related to recognition of acquired tax benefits (US Diagnostics operating segment). During fiscal 2006, the change in goodwill was an increase of $1,085,000. This change

consisted of an increase related to the Viral Antigens earnout obligation for fiscal 2006 in the amount of $853,000 (Life Science operating segment), an increase related to the OEM Concepts earnout obligations for calendar 2005 and the first nine months of calendar 2006 in the amount of $265,000 (Life Science operating segment), offset by a decrease of $33,000 related to recognition of acquired tax benefits (US Diagnostics operating segment).

A summary of Meridian’s acquired intangible assets subject to amortization, as of September 30, 2007 and 2006 is as follows (dollars in thousands).

The actual aggregate amortization expense for these intangible assets for fiscal 2007 was $1,632,000. The aggregate amortization expense for these intangible assets for fiscal 2006 and fiscal 2005 was $2,560,000 and $1,563,000, respectively. The amortization expense for fiscal 2006 included an impairment charge of $826,000 on a supply agreement discussed below. The estimated aggregate amortization expense for these intangible assets for each of the five succeeding fiscal years is as follows: fiscal 2008 — $1,478,000, fiscal 2009 — $1,377,000, fiscal 2010 — $1,339,000, fiscal 2011- $1,266,000 and fiscal 2012 — $1,121,000.

SFAS No. 144, Accounting for Impairment or Disposal of Long-lived Assets establishes a single model for accounting for impairment or disposal of long-lived assets. Long-lived assets, excluding goodwill and identifiable intangibles with indefinite lives, are reviewed for impairment when events or circumstances indicate that such assets may not be recoverable at their carrying value. Whether an event or circumstance triggers an impairment is determined by comparing an estimate of the asset’s future cash flows to its carrying value. If impairment has occurred, it is measured by a fair-value based test. During fiscal 2006, we determined that the carrying value of a supply contract with the US Department of Defense related to the Life Science operating segment had become impaired and recorded such impairment in the amount of $826,000 to general and administrative expenses. The impairment was measured by comparing the present value of expected future cash flows to the carrying value of the contract. The contract provided for the supply of biological materials during a base period and also contained four optional 12-month renewal periods through March 31, 2009. Changes in the Department’s Critical Reagents Program lowered the amount of materials to be supplied under the contract. During March 2007, the Department informed Meridian that it would not be exercising the optional renewal period from April 1, 2007 through March 31, 2008. Meridian does not expect to supply any more materials under this contract, and as of September 30,

		2007, the carrying value of this contract was zero. There have been no events or circumstances indicating that the carrying value of other such assets may not be recoverable.
		Meridian’s ability to recover its intangible assets, both identifiable intangibles and goodwill, is dependent upon the future cash flows of the related acquired businesses and assets. The application of SFAS Nos. 142 and 144 requires management to make judgments and assumptions regarding future cash flows, including sales levels, gross profit margins, operating expense levels, working capital levels, and capital expenditures. With respect to identifiable intangibles and fixed assets, management also makes judgments and assumptions regarding useful lives.
		Management considers the following factors in evaluating events and circumstances for possible impairment: (i) significant under-performance relative to historical or projected operating results, (ii) negative industry trends, (iii) sales levels of specific groups of products (related to specific identifiable intangibles), (iv) changes in overall business strategies and (v) other factors.
		If actual cash flows are less favorable than projections, this could trigger impairment of intangible assets and other long-lived assets. If impairment were to occur, this would negatively affect overall results of operations.
(j)		Revenue Recognition — Revenue is generally recognized from sales when product is shipped and title has passed to the buyer. Revenue for the US Diagnostics operating segment is reduced at the date of sale for estimated rebates that will be claimed by customers. Management estimates accruals for rebate agreements based on historical statistics, current trends, and other factors. Changes to the accruals are recorded in the period that they become known. Our rebate accruals were $2,415,000 at September 30, 2007 and $2,181,000 at September 30, 2006.
		Life Science revenue for contract services may come from standalone arrangements for process development and/or optimization work (contract research and development services) or custom manufacturing, or multiple-deliverable arrangements that include process development work followed by larger-scale manufacturing (both contract research and development services and contract manufacturing services). Revenue is recognized based on the nature of the arrangements, using the principles in EITF 00-21, Revenue Arrangements with Multiple Deliverables. The framework in EITF 00-21 is based on each of the multiple deliverables in a given arrangement having distinct and separate fair values. Fair values are determined via consistent pricing between standalone arrangements and multiple deliverable arrangements, as well as a competitive bidding process. Contract research and development services may be performed on a “time and materials” basis or “fixed fee” basis. For “time and materials” arrangements, revenue is recognized as services are performed and billed. For “fixed fee” arrangements, revenue is recognized upon completion and acceptance by the customer. For contract manufacturing services, revenue is recognized upon delivery of product and acceptance by the customer.

		Trade accounts receivable are recorded in the accompanying consolidated balance sheet at invoiced amounts less provisions for rebates and doubtful accounts. The allowance for doubtful accounts represents our estimate of probable credit losses and is based on historical write-off experience. The allowance for doubtful accounts and related metrics, such as days sales outstanding, are reviewed monthly. Accounts with past due balances over 90 days are reviewed individually for collectibility. Customer invoices are charged off against the allowance when we believe it is probable the invoices will not be paid.
(k)		Research and Development Costs - Research and development costs are charged to expense as incurred. Research and development costs include, among other things, salaries and wages for research scientists, materials and supplies used in the development of new products, and costs for facilities and equipment.
(l)		Income Taxes — The provision for income taxes includes federal, foreign, state, and local income taxes currently payable and those deferred because of temporary differences between income for financial reporting and income for tax purposes. We prepare estimates of permanent and temporary differences between income for financial reporting purposes and income for tax purposes. These differences are adjusted to actual upon filing of our tax returns, typically occurring in the third and fourth quarters of the current fiscal year for the preceding fiscal year’s estimates. See Note 7.
(m)		Stock-based Compensation – We account for stock-based compensation pursuant to SFAS No. 123R, Share-Based Payment, which was adopted as of July 1, 2005. SFAS No. 123R requires recognition of compensation expense for all share-based awards made to employees, based upon the fair value of the share-based award on the date of the grant. Meridian elected to adopt the provisions of SFAS No. 123R, utilizing the modified prospective method, which required compensation expense be measured and recognized based on grant-date fair value for stock option awards granted after July 1, 2005 and the non-vested portions of stock options awards granted prior to July 1, 2005. See Note 8(b).

Derivative Financial Instruments – We account for our derivative financial instruments in accordance with SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended. These instruments are designated as cash flow hedges, and therefore, the effective portion of the net gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. For the ineffective portion of the hedge, gains or losses are charged to earnings in the current period. All derivative instruments are recognized as either assets or liabilities at fair value in the consolidated balance sheets. Cash flows from our hedging instruments are classified in Operating Activities, consistent with cash flows from the related items being hedged. See Note 6.

Comprehensive Income (Loss) – Comprehensive income represents the net change in shareholders’ equity during a period from sources other than transactions with shareholders. Meridian’s comprehensive income
