ON FORM 10-K

FORWARD LOOKING STATEMENTS

This Annual Report on Form 10-K contains forward-looking statements. The Private Securities Litigation Reform Act of 1995 provides a safe harbor from civil litigation for forward-looking statements accompanied by meaningful cautionary statements. Except for historical information, this report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, which may be identified by words such as “estimates”, “anticipates”, “projects”, “plans”, “seeks”, “may”, “will”, “expects”, “intends”, “believes”, “should” and similar expressions or the negative versions thereof and which also may be identified by their context. Such statements, whether expressed or implied, are based upon current expectations of the Company and speak only as of the date made. The Company assumes no obligation to publicly update or revise any forward-looking statements even if experience or future changes make it clear that any projected results expressed or implied therein will not be realized. These statements are subject to various risks, uncertainties and other factors that could cause actual results to differ materially, including, without limitation, the following: Meridian’s continued growth depends, in part, on its ability to introduce into the marketplace enhancements of existing products or new products that incorporate technological advances, meet customer requirements and respond to products developed by Meridian’s competition. While Meridian has introduced a number of internally developed products, there can be no assurance that it will be successful in the future in introducing such products on a timely basis. Meridian relies on proprietary, patented and licensed technologies, and the Company’s ability to protect its intellectual property rights, as well as the potential for intellectual property litigation, would impact its results. Ongoing consolidations of reference laboratories and formation of multi-hospital alliances may cause adverse changes to pricing and distribution. Recessionary pressures on the economy and the markets in which our customers operate, as well as adverse trends in buying patterns from customers can change expected results. Costs and difficulties in complying with laws and regulations, including those administered by the United States Food and Drug Administration, can result in unanticipated expenses and delays and interruptions to the sale of new and existing products. The international scope of Meridian’s operations, including changes in the relative strength or weakness of the U.S. dollar and general economic conditions in foreign countries, can make results difficult to predict. One of Meridian’s growth strategies is the acquisition of companies and product lines. There can be no assurance that additional acquisitions will be consummated or that, if consummated, will be successful and the acquired businesses will be successfully integrated into Meridian’s operations. There may be risks that acquisitions may disrupt operations and may pose potential difficulties in employee retention and there may be additional risks with respect to Meridian’s ability to recognize the benefits of acquisitions, including potential synergies and cost savings or the failure of acquisitions to achieve their plans and objectives. The Company cannot predict the possible impact of recently-enacted United States healthcare legislation and any similar initiatives in other countries on its results of operations. In addition to the factors described in this paragraph, Part I, Item 1A Risk Factors contains a list and description of uncertainties, risks and other matters that may affect the Company.

Reportable Segments

Our reportable segments are U.S. Diagnostics, European Diagnostics and Life Science. The U.S. Diagnostics segment consists of manufacturing operations in Cincinnati, Ohio, and the sale and distribution of diagnostic test kits in the U.S. and countries outside of Australia, Europe, Africa and the Middle East. The European Diagnostics segment consists of the sale and distribution of diagnostic test kits in Australia, Europe, Africa and the Middle East. The Life Science segment consists of manufacturing operations in Memphis, Tennessee; Boca Raton, Florida; London, England; Luckenwalde, Germany; and Sydney, Australia, and the sale and distribution of bulk antigens, antibodies, PCR/qPCR reagents, nucleotides, competent cells and bioresearch reagents domestically and abroad. The Life Science segment also includes the contract development and manufacture of cGMP clinical grade proteins and other biologicals for use by biopharmaceutical and biotechnology companies engaged in research for new drugs and vaccines. Financial information for Meridian’s segments is included in Note 8 to the consolidated financial statements.

Our primary source of revenues continues to be diagnostic products, with our Diagnostics segments providing 75% of consolidated net sales for fiscal 2012. 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. The acquisition of the Bioline group of companies (collectively the “Bioline Group”) in July 2010 dramatically increased the revenue base for our Life Science segment; revenues for our Life Science segment represented 25% of consolidated net sales for fiscal 2012.

Products and Markets

We have expertise in the development and manufacture of products based on multiple core diagnostic technologies. Our product technologies include DNA amplification, 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 clinical diagnostic products.

Sales within our focus product families – C. difficile, foodborne and H. pylori – accounted for 62%, 58% and 51% of our U.S. Diagnostics segment’s third-party sales during fiscal 2012, 2011 and 2010, respectively. These same product families accounted for 47%, 44% and 43% of consolidated net sales in fiscal 2012, 2011 and 2010, respectively.

U.S. Diagnostics Segment

Overview

Our U.S. Diagnostics segment’s business focuses on the development, manufacture, sale and distribution of diagnostic test kits, primarily for certain gastrointestinal, viral, respiratory 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 segment were $108,000, $97,000 and $92,000 for fiscal 2012, 2011 and 2010, respectively, reflecting a three-year compound annual growth rate of 3%. Excluding influenza-related sales, the three-year compound annual growth rate was 8%. The higher rate reflects the impact of influenza-related sales in 2009 in connection with the H1N1 influenza pandemic. As of September 30, 2012, our U.S. Diagnostics segment had approximately 290 employees.

Our diagnostic test kits utilize immunodiagnostic and molecular technologies, which test samples of stool, blood, urine and other body fluids or tissue for the presence 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. During fiscal 2010 we commercialized our molecular amplification diagnostic testing platform, illumigene^®, and introduced our first assay, C. difficile. The illumigene^® C. difficile assay detects the presence of the toxin producing region from the C. difficile DNA, and provides highly accurate results in under an hour. Throughout fiscal 2011 and fiscal 2012, we continued with the development of additional tests for the illumigene^® molecular platform, receiving FDA clearance for our second and third molecular tests for the platform – illumigene^® Group B Streptococcus (Group B Strep or GBS) in December 2011 and illumigene^® Group A Streptococcus (Group A Strep) in September 2012. A test for Mycoplasma pneumoniae (Walking Pneumonia) was recently submitted to the FDA for marketing clearance and is expected to be available for sale in the U.S. during the second quarter of fiscal 2013. Our fifth test on the illumigene^® platform is for Bordetella pertussis (Whooping Cough), which is expected to be available for sale in the U.S. during the third or fourth quarter of fiscal 2013. Our development pipeline for illumigene^® also includes two sexually-transmitted disease assays, expected to be available for sale in the U.S. during the first half of fiscal 2014.

Our diagnostic products are used principally in the detection of gastrointestinal diseases, such as antibiotic-associated diarrhea (C. difficile), pediatric diarrhea (Rotavirus and Adenovirus) and stomach ulcers (H. pylori); foodborne diseases such as Enterohemorrhagic E. coli infection (EHEC) and Campylobacter jejuni (Campy); Streptococcus bacterial infections (both Group A and Group B Strep); viral diseases, such as Mononucleosis, Herpes Simplex, Chicken Pox and Shingles (Varicella-Zoster) and Cytomegalovirus (organ transplant infections); parasitic diseases, such as Giardiasis, Cryptosporidiosis and Lyme; and respiratory diseases, such as Pneumonia, Valley Fever, Influenza and Respiratory Syncytial Virus (RSV). The primary markets and customers for these products are reference laboratories and hospitals.

Table of Contents

In particular, the three tests we currently offer on our illumigene^® platform – C. difficile, Group A Strep and Group B Strep – are expected to drive the majority of growth in fiscal 2013.

C. difficile

Clostridium difficile (C. difficile) is a bacteria found in the gut that can cause serious damage to the colon and even death, primarily in hospital patients using antibiotics. It is the most common infection acquired by patients while they are in the hospital. Annually in the U.S., an estimated 8 million C. difficile tests are performed. This hospital acquired infection occurs when antibiotics disrupt other bacteria that normally prevent the colonization of C. difficile. Rapid, accurate diagnosis, followed by appropriate treatment is essential to improving patient outcomes and reducing the overall cost of care. Our strong line of C. difficile tests, including our illumigene^® C. difficile molecular test, provide the most comprehensive and accurate testing options for this serious and life threatening infection.

Group A Strep

Group A Streptococcus is the bacterium commonly found in the throat which causes strep throat (acute pharyngitis). Pharyngitis is diagnosed in approximately 11 million patients in the U.S. each year. Our illumigene^® Group A Strep test, the only FDA-cleared molecular Strep A test in the U.S. market, provides results in less than one hour, detects more positives than culture methods and is ideal for early diagnosis and proper patient management of the common, sometimes serious disease. In addition to front line testing in hospital and clinical settings, rapid strep throat tests performed in physician offices in the U.S. that are negative are routinely sent on to hospital and reference labs for confirmation testing, usually by culture methods that take up to 48 hours to run. With results in less than one hour and a 53% increase in the detection of positives, illumigene^® Group A Strep provides improved patient care over culture methods.

Group B Strep

Each year in the U.S. there are over 4 million babies born. Appropriately testing women in the late stages of pregnancy for the presence of Group B Streptococcus is critical to the health of the baby. Without proper treatment during labor, GBS infection can lead to sepsis, pneumonia and even meningitis, and lead to hearing and vision loss. Testing with our illumigene^® GBS improves accuracy by up to 29% over traditional culture methods, increasing the likelihood of improved outcomes and a healthy baby.

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.

Table of Contents

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 overall treatment expense. In addition, these pressures have led to a major consolidation among reference laboratories and the formation of multi-hospital group purchasing organizations and integrated delivery networks 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.

Sales and Marketing

Our U.S. Diagnostics segment’s sales and distribution network in the U.S. consists of a direct sales force complemented by independent distributors. The use of independent distributors in the U.S. allows our products to reach any bed-size healthcare facility and also provides our customers the option to purchase our products direct or through distribution along with other supplies. For our export markets in Asia, Canada and South America, we use independent distributors. Two independent distributors in the U.S. accounted for 10% or more of consolidated net sales in fiscal 2012, 2011 and 2010: Cardinal Healthcare Corporation and Fisher Scientific. Our sales to Cardinal were approximately $33,000, $30,000 and $34,000 during fiscal 2012, 2011 and 2010, respectively. Our sales to Fisher were approximately $20,000, $18,000 and $18,000 during fiscal 2012, 2011 and 2010, respectively.

Consolidation of the U.S. 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 group purchasing organizations, integrated delivery networks and major reference laboratories to stabilize pricing.

Clostridium difficile

C. difficile, a serious hospital acquired bacterial infection, is our largest product family, generating approximately $36,000 in global sales for fiscal 2012, or 21% growth from fiscal 2011. This product family has experienced significant competition over the last three years from new technologies, including molecular testing platforms. Our illumigene^® molecular C. difficile product has now been available in markets around the world for over two years. Sales of this product were approximately $22,000, $9,000 and $500 in fiscal 2012, 2011 and 2010, respectively. Approximately 950 clinical laboratories are current customers using our illumigene^® platform, which now includes three tests (see below for a discussion of our second and third tests for Group B and Group A Strep). While the majority of these customers have adopted the C. difficile assay, a growing number of customers are purchasing multiple assays for the platform. Our illumigene^® molecular C. difficile product has restored the C. difficile product family to positive sales growth, 21% and 10% during each of the last two fiscal years.

Table of Contents

Our major competitors in this product family are Cepheid and Becton Dickinson (molecular) and Alere (immunoassay). We believe that we have two principal advantages versus our competition. First, our molecular instrumentation package has a smaller footprint and significantly lower cost than either Cepheid or Becton Dickinson. We believe that this advantage allows our product to fit into virtually any size hospital or reference laboratory. We believe that our second principal advantage is the breadth of our C. difficile product offerings. With the launch of our molecular product and FDA clearance of our common antigen C. difficile products – Premier C. difficile GDH received FDA clearance in May 2011, and ImmunoCard C. difficile GDH received FDA clearance in December 2011 – we believe we are in a unique position to offer a full line of testing solutions to our clinical laboratory customers around the world to counter the competitive pressures surrounding this market. Additionally, we hold the only FDA-approved claim for C. difficile testing in the pediatric population. These advantages, along with the performance features of the products in our C. difficile portfolio, give us a compelling product offering for any hospital testing method preference.

During fiscal 2012, we received FDA clearance for our second and third molecular tests for the illumigene^® molecular platform – illumigene^® GBS (Group B Streptococcus) in December 2011 and illumigene^® Group A Strep (Group A Streptococcus) in September 2012. As alluded to above, over 100 customers are now purchasing two assays for the illumigene^® platform – the majority being C. difficile and GBS – with revenue generated by our GBS test approximating $1,100 during fiscal 2012. In addition, with the recent introduction of the Group A Strep test, there are a growing number of customers adopting all three of our molecular-platform assays. A test for Mycoplasma pneumoniae was recently submitted to the FDA for marketing clearance and is expected to be available for sale in the U.S. during the second quarter of fiscal 2013. Our fifth test on the illumigene^® platform is for Bordetella pertussis, which is expected to be available for sale in the U.S. during the third or fourth quarter of fiscal 2013. Our development pipeline for illumigene^® also includes two sexually-transmitted disease assays, expected to be available for sale in the U.S. during the first half of fiscal 2014.

In addition to Cepheid, Becton Dickinson and Alere, other competitors have begun to enter the C. difficile market. During fiscal 2012, Quest Diagnostics and Great Basin received FDA clearance for a molecular C. difficile test and Quidel received CE marking approval for a molecular C. difficile test for sale within the European Union. Although we believe that the breadth of our C. difficile product offerings and our low cost molecular platform provide key advantages to the offerings of our competitors, selling prices may come under pressure as more competitors enter the market.

Foodborne

Our foodborne product family achieved approximately $21,000 in global sales for fiscal 2012, or growth of 13%, with over 95% of such sales occurring in the U.S. Our foodborne products include tests for Enterohemorrhagic E. coli (EHEC) and Campylobacter jejuni (Campy). In the U.S. market, we believe that there are potentially 20 million annual stool cultures that are tested for foodborne illnesses. At present, we believe that we have less than a 20% market share for EHEC and less than a 5% market share for Campy.

While historically the primary competition for our foodborne products has been laboratory culture methods, one of our competitors, Alere, has recently cleared through the FDA a shiga toxin test that will compete with our EHEC test. We believe that our products have two principal advantages versus culture methods. The first principal advantage is test accuracy. Independent evaluations have shown our products to have higher sensitivity than culture methods. The second principal advantage is improved work flow of the testing process, resulting in significantly shortened time to test result. Our single-use rapid products provide a test result in approximately 20 minutes, whereas culture results can take up to 24-48 hours. Time to test result can be a critical factor in the physician’s choice of therapies, as the mortality rate for EHEC is estimated to be 5% to 10%.

Helicobacter pylori

H. pylori, a bacterium found in the stomach, is a major cause of peptic ulcers and is linked to duodenal ulcers and stomach cancer. H. pylori represents our second largest product family, generating approximately $24,000 in global sales for 2012, or 7% growth. We offer both antibody and direct antigen tests in alternative formats (single-use and high volume batch). Our major competition in this product family are test-method alternatives, serology and urea breath, and the prescription of symptom-relieving medications. In the U.S., our strategy has been to partner with managed care companies to promote the health and economic benefits of a test and treat strategy, and to move physician behavior away from serology-based testing toward direct antigen testing. In the U.S. market, we believe that there are potentially 30 million people suffering from peptic ulcers and we believe that we currently have a 5% market share.

In European markets, we face a greater number of competitive products for this product family. As a result, pricing pressures have led to 3% sales growth for fiscal 2012 for our European Diagnostics segment, excluding the effect of currency translation.

Research and Development

Our U.S. Diagnostics segment’s research and development organization has expertise in biochemistry, immunology, mycology, bacteriology, virology, parasitology and molecular biology. Research and development expenses for the U.S. Diagnostics segment for fiscal 2012, 2011 and 2010 were approximately $8,000, $7,000 and $6,000, 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. The products within our C. difficile, foodborne, and H. pylori product families were either developed solely in-house, or via collaboration with outside partners.

The introduction of our molecular amplification diagnostic testing platform, illumigene^®, introduced in markets around the world over two years ago, followed nearly four years of exploration and development of a molecular-based diagnostic testing technology to complement our existing antigen/antibody-based testing technologies. Our illumigene^® C. difficile assay, the initial assay introduced for the illumigene^® platform, detects the presence of a key toxin producing region from the C. difficile DNA, and provides highly accurate results in under an hour. We believe this molecular assay uniquely positions us in the market to provide a full line of testing solutions that will meet the needs of both our domestic and international customers and, as a result, throughout fiscal 2011 and fiscal 2012, we continued with the development of additional tests for the illumigene^® molecular platform, receiving FDA clearance for our second and third molecular tests for the platform – illumigene^® GBS (Group B Streptococcus) in December 2011 and illumigene^® Group A Strep (Group A Streptococcus) in September 2012. A test for Mycoplasma pneumoniae (Walking Pneumonia) was recently submitted to the FDA for marketing clearance and is expected to be available for sale in the U.S. during the second quarter of fiscal 2013. Our fifth test on the illumigene^® platform is for Bordetella pertussis (Whooping Cough), which is expected to be available for sale in the U.S. during the third or fourth quarter of fiscal 2013. Our development pipeline for illumigene^® also includes two sexually-transmitted disease assays, expected to be available for sale in the U.S. during the first half of fiscal 2014. We currently hold registrations to sell illumigene^® in 37 countries, including the U.S., with registrations pending in 5 additional countries.

During fiscal 2008, we launched our first products under our patented TRU rapid test technology. The design of this technology enhances laboratory safety by containing the specimen in a closed system during testing as recommended by CDC guidelines. TRU tests also use less space than other immunoassay technologies, which is an advantage in space-constrained clinical laboratories. Products using this technology include TRU FLU^®, TRU RSV^®, TRU EBV-M^® and TRU EBV-G^®. TRU LEGIONELLA^TM and TRU HSV 1 and 2 IgG^TM the latest additions to the TRU line of products. Legionella was launched in foreign markets during the fourth quarter of fiscal 2011, and became available in the U.S. market during the second quarter of fiscal 2012, while TRU HSV 1 and 2 IgG^TM were registered for sale in Europe during September 2012.

Manufacturing

Our immunodiagnostic and molecular products require the production of highly specific and sensitive antigens, antibodies, primers and enzymes. While we produce substantially all of our own requirements including monoclonal antibodies and polyclonal antibodies, plus a variety of fungal, bacterial and viral antigens, currently a number of the raw materials used in our products, including our illumigene^® molecular products, are purchased from outside vendors. We believe that we have sufficient manufacturing and sourcing capacity for anticipated growth in the near term.

Intellectual Property, Patents and Licenses

We own or license U.S. and foreign patents, most of which are for products manufactured by our U.S. Diagnostics segment. Sales of these products are as follows:

The patents for the illumigene^® products expire between 2020 and 2022; the patents for the two H. pylori products expire between 2016 and 2017; and the patents for the three respiratory products expire in 2022 (two products) and 2027. The remaining six patented products for which we own or license patents are spread over three product families.

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.

- 11 -

Table of Contents

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; however, we can make no assurances in this regard.

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.

Meridian’s Cincinnati manufacturing facility is certified to ISO 13485:2003.

Medical Device Tax

Included within the U.S. government’s comprehensive healthcare reform legislation, enacted during 2010, was the establishment of a 2.3% excise tax on the sales of medical devices beginning in calendar 2013. We currently anticipate that this legislation will result in an excise tax for our company of approximately $2,000 in fiscal 2013. At the present time it is believed that little, if any, of this cost can be passed on to customers.

Seasonal Factors and Sporadic Outbreaks

Our principal business is the sale of a broad range of diagnostic test kits for common gastrointestinal, viral, upper respiratory and parasitic infectious diseases. Certain infectious diseases may be seasonal in nature, while others may be associated with sporadic outbreaks, such as foodborne illnesses, or pandemics such as the H1N1 influenza outbreak during fiscal 2009. While we believe that the breadth of our diagnostic product lines reduces the risk that infections subject to seasonality and sporadic outbreaks will cause significant variability in diagnostic revenues, we can make no assurance that revenues will not be impacted period over period by such factors.

European Diagnostics Segment

Our European Diagnostics segment’s business focuses on the sale and distribution of diagnostic test kits, manufactured both by our U.S. Diagnostics segment and by third-party vendors. Approximately 85% of third-party sales for fiscal 2012 for this segment were products purchased from our U.S. Diagnostics segment. Third-party sales for this segment were approximately $23,000, $24,000 and $24,000 for fiscal 2012, 2011 and 2010, respectively. As of September 30, 2012, the European Diagnostics segment had approximately 40 employees. Our European Diagnostics segment’s sales and distribution network consists of direct sales forces in Australia, Belgium, France, Holland and Italy, and independent distributors in other European countries, Africa and the Middle East. The European Diagnostics segment maintains a distribution center near Milan, Italy. The primary markets and customers for this segment are hospitals and reference laboratories.

Life Science Segment

Overview

Our Life Science segment’s business focuses on the development, manufacture, sale and distribution of bulk antigens, antibodies, PCR/qPCR reagents, nucleotides, competent cells and bioresearch 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 segment were approximately $43,000, $38,000 and $27,000 for fiscal 2012, 2011 and 2010, respectively. As of September 30, 2012, our Life Science segment had approximately 180 employees.

Most of the revenue for our Life Science segment currently comes from the manufacture, sale and distribution of bulk antigens, antibodies, PCR/qPCR reagents, nucleotides, competent cells and bioresearch reagents used by researchers and other diagnostic companies. During fiscal 2012, 19% of third-party sales for this segment were to two diagnostic manufacturing customers. For one of these two customers, we have 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.

In July 2010, we acquired the Bioline Group and in so doing added important technologies and capabilities to our Life Science business and complemented our expanding life science product lines sold into the research, pharmaceutical and commercial diagnostic markets. In addition to technological capabilities, Bioline also added proprietary know-how in the production of high-volume nucleotides and PCR enzymes, as well as a growing portfolio of intellectual property in the form of patents and licenses. The Bioline Group contributed approximately $17,000 and $15,000 in sales for fiscal 2012 and 2011, respectively.

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. Revenues for our Life Science 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 our immunodiagnostic and molecular biology products, as well as buying patterns of major customers. See Note 1 (i) to the Consolidated Financial Statements herein for revenue recognition policies. Our revenues for contract services were approximately $2,000, $3,000 and $2,000 in fiscal 2012, 2011 and 2010, respectively.

As a result of the order volume trends in bulk antigens, antibodies and reagents, during the fourth quarter of fiscal 2011, we announced the closure of our Saco, Maine facility, and completed the consolidation of manufacturing operations into our Memphis, Tennessee facility during the third fiscal quarter of 2012. Total costs to complete the consolidation of facilities approximated $2,100, consisting of fixed asset impairments, inventory impairments, stay bonuses and moving costs, among other similar items. During the fourth quarter of 2011, we recognized approximately $1,100 of these costs, and recognized the remaining $1,000 during the first three quarters of fiscal 2012.

Products, Markets and Growth Strategies

Our Life Science segment’s businesses have been assembled via acquisitions (BIODESIGN International in fiscal 1999, Viral Antigens in fiscal 2000, OEM Concepts in fiscal 2005, and the Bioline Group in July 2010). Historically, these businesses were run autonomously. In recent years, growth strategies have been developed around sales and marketing integration, new product development integration, and the acquisition of complementary product lines.

Immunodiagnostic products such as antibodies, antigens and reagents 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 products are typically sold in bulk quantities, and may also be custom-designed for a particular manufacturer’s requirements. 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.

Molecular biology products such as PCR/qPCR reagents, nucleotides and competent cells are marketed primarily to research customers. These products are typically sold in small quantities.

Research and Development

Research and development expenses for our Life Science segment for fiscal 2012, 2011 and 2010 were approximately $2,000, $3,000 and $2,000, respectively. This research and development organization is heavily involved in vaccine development and production activities for our cGMP facility and development of new molecular components.

Manufacturing and Government Regulation

The cGMP clinical grade proteins that are produced in our Memphis facility are intended to be used as “injectibles,” and, 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.

The Meridian Life Science facilities are ISO 9001:2000 certified and EC 1069:2009 approved, where appropriate and as required.

Competition

Diagnostics

The market for diagnostic tests is a multi-billion dollar international industry, which is highly competitive. Many of our competitors are larger than we are with greater financial, research, manufacturing and marketing resources. Important competitive factors for 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 the diagnostic product divisions of Abbott Laboratories Inc., Becton, Dickinson and Company, Thermo Fisher and Siemens. We also compete with smaller companies such as Cepheid, Quidel Corporation and Alere, Inc.

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, and 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 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 additional acquisitions in the future, nor can we provide any assurance that any acquisitions will accomplish these objectives, we expect that the potential for acquisitions will continue to provide opportunities for 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 segments. For all segments combined, international sales were approximately $54,000 or 31% of consolidated fiscal 2012 sales, $53,000 or 33% of consolidated fiscal 2011 sales and $43,000 or 30% of consolidated fiscal 2010 sales. We expect to continue to look to international markets as a source of new revenues and growth in the future. See Notes 6 and 8 to the Consolidated Financial Statements for information concerning sales, long-lived assets and deferred tax assets by country.

Environmental

We are a conditionally exempt, small quantity generator of hazardous waste and have a U.S. EPA identification number. 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.

- 16 -

Table of Contents

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.

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

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

Key Distributors

Our U.S. Diagnostic segment’s sales through two national distributors were 49% of the U.S. Diagnostics segment’s total sales for both fiscal 2012 and 2011, or 30% of our consolidated sales for both fiscal 2012 and 2011. 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.

In addition, buying patterns of these two distributors may fluctuate from quarter to quarter, potentially leading to uneven concentration levels on a quarterly basis.

- 17 -

Table of Contents

Seasonal Factors and Sporadic Outbreaks

Our principal business is the sale of a broad range of diagnostic test kits for common gastrointestinal, viral, upper respiratory and parasitic infectious diseases. Certain infectious diseases may be seasonal in nature, while others may be associated with sporadic outbreaks, such as foodborne illnesses, or pandemics such as H1N1 influenza. While we believe that the breadth of our diagnostic product lines reduces the risk that infections subject to seasonality and sporadic outbreaks will cause significant 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. Consolidation in the U.S. healthcare industry has also led to the creation of group purchasing organizations (GPOs) and integrated delivery networks (IDNs) that aggregate buying power for hospital groups and put pressure on our selling prices. 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, GPOs and IDNs, which could adversely affect our results of operations.

We could be adversely affected by healthcare reform legislation.

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. Following years of increasing pressure, during 2010 the U.S. government enacted comprehensive healthcare reform. At present, given the infancy of the enacted reform, we are unable to predict what effect the legislation might ultimately have on reimbursement rates for our products. 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 results of operations.

In addition, this legislation established a 2.3% excise tax on the sales of medical devices beginning in calendar 2013. We currently anticipate that this legislation will result in an excise tax for our company of approximately $2,000 in fiscal 2013. At the present time it is believed that little, if any, of this cost can be passed on to customers.

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

Our Life Science segment’s sales of purified antigens and reagents to two diagnostics manufacturing customers were 19% and 15%, respectively, of the Life Science segment’s total sales for fiscal 2012 and fiscal 2011, or 5% and 4%, respectively, of our consolidated sales for fiscal 2012 and fiscal 2011. For one of these two customers, we have 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.

- 18 -

Table of Contents

Our Life Science segment has four other significant customers who purchase antigens, antibodies and reagents, which together comprised 9% and 10%, respectively, of the segment’s total sales for fiscal 2012 and fiscal 2011. 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 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. While this business has historically generated annual revenue of approximately $2,000 to $4,000, 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.

In recent years, molecular tests have been introduced for the first time into the C. difficile market, which is a significant source of revenues for us. Our ability to continue to successfully compete in the C. difficile market is partly dependent upon the success and market acceptance of our own molecular-based product, illumigene^® C. difficile.

We depend 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 2012 and approximately 33% of our net sales for fiscal 2011 were attributable to international markets. For fiscal 2012, approximately 40% of our international sales were made in Euros and 40% were made in U.S. dollars, with the remaining 20% being a combination of the British pound and the Australian dollar. We are subject to the risks associated with fluctuations in the exchange rates for the Australian dollar, British pound and Euro to the U.S. dollar. We are also subject to other risks associated with international operations, including longer customer payment cycles, tariff regulations, requirements for export licenses, instability of foreign governments, and governmental requirements with respect to the importation and distribution of medical devices and immunodiagnostic and molecular biology reagents, all of which may vary by country.

Table of Contents

In addition, in recent months there have been a number of media reports that have called into question the longevity of the Euro currency, and whether certain countries might exit the Euro currency. We have no opinion on the longevity of the Euro currency, or if any countries ultimately will exit the Euro currency. In the event that the Euro currency would completely dissolve, or in the event certain countries exited the Euro currency, the carrying value of our assets and liabilities in European countries where we have a direct presence could be materially affected as legacy currencies are re-implemented. We continue to monitor this situation and have begun to prepare contingency plans.

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, the Centers for Disease Control or other regulators 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; London, England; Luckenwalde, Germany; and Sydney, Australia facilities comprised 77% of our Diagnostics revenues and 83% 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 and product components. 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, tornadoes 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.

- 20 -

Table of Contents

We depend 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 multiple 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.

We currently sole-source from a U.S. manufacturer the illumipro-10^® instrument on which our illumigene^® molecular testing platform operates. Additionally, two of our foodborne products sourced from another vendor accounted for 15%, 14% and 11% of third-party sales for our U.S. Diagnostics segment in fiscal 2012, 2011 and 2010, respectively.

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 and retaining 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 third-party 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. We currently carry intellectual property insurance that covers damages and defense costs from our potential infringement on other third-party patents at levels that we believe are commercially reasonable, although there is no assurance that it will be adequate to cover claims that may arise. 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.

- 21 -

Table of Contents

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.

We face risks related to global economic conditions.

We currently generate significant operating cash flows, which combined with access to the credit markets provides us with discretionary funding capacity for research and development and other strategic activities. However, as an enterprise with global operations and markets, our operations and financial performance are in part dependent upon global economic conditions, and we could be negatively impacted by a global, regional or national economic crisis, including sovereign risk in the event of deterioration in the credit worthiness of or a default by local governments. We are particularly susceptible to the economic conditions in countries where government-sponsored healthcare systems are the primary payers for healthcare, including those countries within the European Union that are reducing their public expenditures in an effort to achieve cost savings. The uncertainty in global economic conditions poses a risk to the overall economy that could impact demand for our products, as well as our ability to manage normal commercial relationships with our customers, suppliers and creditors, including financial institutions. As such, if global economic conditions deteriorate significantly, our business could be negatively impacted, including such areas as reduced demand for our products from a slow-down in the general economy, supplier or customer disruptions resulting from tighter credit markets and/or temporary interruptions in our ability to conduct day-to-day transactions through our financial intermediaries involving the payment to or collection of funds from our customers, vendors and suppliers. While to-date such factors have not had a significant negative impact on our results or operations, we continue to monitor and plan for the potential impact of these global economic factors. See a discussion of Euro currency risk in the above risk factor related to international market activities.

Approximately $4,600 of our accounts receivable at September 30, 2012 is due from Italian hospital customers whose funding ultimately comes from the Italian government. During the fourth quarter of fiscal 2011 and first quarter of fiscal 2012, we experienced a deterioration in the aging of our Italian accounts receivable. While such aging appeared to stabilize during fiscal 2012, we continue to monitor such accounts closely.

Risks Related to Our Common Stock

Our board of directors has the authority to issue up to 1,000 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.

MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Refer to “Forward Looking Statements” following the Index in front of the Form 10-K and Item 1A “Risk Factors” on Pages 16 through 23 of this Annual Report .

“Common Stock Information” on the inside back cover of the Annual Report to Shareholders for 2012 and “Quarterly Financial Data (Unaudited)” relating to our dividends in Note 10 to the Consolidated Financial Statements are incorporated herein by reference. Except as may otherwise be prohibited by applicable law, there are no restrictions on cash dividend payments.

During fiscal 2012, our indicated annual dividend rate of $0.76 per share approximated 95% of full year diluted earnings per share, nearly in line with our long-standing policy of setting a cash dividend payout ratio of between 75% and 85% of each fiscal year’s expected net earnings. This 2012 payout ratio reflects an improvement over the course of the fiscal year – from 118% in the first quarter to 90% in the third and fourth quarters – and follows two fiscal years in which our cash dividend payout ratio approximated 115% of diluted earnings per share. We believe that this positive dividend payout relationship will continue, although no assurances can be made in this regard. The declaration and amount of dividends will be determined by the Board of Directors in its discretion based upon its evaluation of earnings, cash flow requirements and future business developments and opportunities, including acquisitions.

We paid dividends of $0.76 per share in each of fiscal 2012 and fiscal 2011, and $0.74 per share in fiscal 2010.

As of September 30, 2012, there were approximately 950 holders of record and approximately 17,600 beneficial owners of our common shares.

Refer to “Forward Looking Statements” following the Index in front of this Form 10-K and Item 1A “Risk Factors” on pages 16 through 23 of this Annual Report.

In the discussion that follows, all amounts are in thousands (both tables and text), except per share data.

Results of Operations:

Fourth Quarter

Net earnings for the fourth quarter of fiscal 2012 increased 28% to $8,573, or $0.21 per diluted share, from net earnings for the fourth quarter of fiscal 2011 of $6,710, or $0.16 per diluted share. This increase reflects the combined effects of both increased sales and increased operating expenses. Additionally, the fiscal 2011 fourth quarter included $1,057 of costs associated with the consolidation of the Saco, Maine operations into the Memphis, Tennessee facility (impact on net earnings of $691, or $0.02 per diluted share – see Non-GAAP Information below). Sales for the fourth quarter of fiscal 2012 were $43,694, an increase of $2,345, or 6%, compared to the fourth quarter of fiscal 2011, reflecting increased sales across all of our diagnostic focus product families: C. difficile, Foodborne and H. pylori.

Sales for the U.S. Diagnostics segment for the fourth quarter of fiscal 2012 increased 11% compared to the fourth quarter of fiscal 2011, reflecting growth across all of our focus product families – ranging from 9% growth in H. pylori products to 20% growth in our C. difficile product family. Fourth quarter 2012 sales for our European Diagnostics segment decreased 11% compared to the fourth quarter of fiscal 2011 due primarily to a negative currency effect. On an organic basis, which excludes the effects of currency translation, sales for our European Diagnostics segment were flat during the fourth quarter, reflecting growth in H. pylori product sales being offset by a decline in sales of our C. difficile and foodborne product families. Reflecting growth in its molecular reagent business being partially offset by a decline in its core bulk reagent business, sales of our Life Science segment increased by 1% during the fourth quarter of fiscal 2012 compared to the fourth quarter of fiscal 2011.

Fiscal Year

Net earnings for fiscal 2012 increased 24% to $33,371, or $0.80 per diluted share from net earnings for fiscal 2011 of $26,831, or $0.65 per diluted share. Fiscal 2012 results includes $1,013 of costs associated with the consolidation of the Saco, Maine operations into the Memphis, Tennessee facility (impact on earnings of $659 or $0.02 per diluted share – see Non-GAAP Information below), while fiscal 2011 included $1,057 of costs related to the Maine facility consolidation and $1,240 of costs incurred in connection with the reorganization of our sales and marketing leadership during the second quarter of fiscal 2011 (combined impact on fiscal 2011 net earnings of $1,563 or $0.04 per diluted share). Results of operations for fiscal 2012 compared to fiscal 2011 are discussed below.

Non-GAAP Information

The tables below provide information on net earnings, basic earnings per share and diluted earnings per share, excluding the effect of costs associated with the consolidation of our Saco, Maine operations into our Memphis, Tennessee facility (fiscal 2012 and fiscal 2011), costs of reorganizing our sales and marketing leadership (fiscal 2011) and transaction costs associated with the acquisition of the Bioline Group (fiscal 2010), each of which is a non-GAAP financial measure, as well as reconciliations to amounts reported under U.S. Generally Accepted Accounting Principles. We believe that this information is useful to those who read our financial statements and evaluate our operating results because:

Revenue Overview:

Our Diagnostics segments provide the largest share of our consolidated revenues, 75%, 76% and 81% for fiscal 2012, 2011 and 2010, respectively. The percentage decline from fiscal 2010 to fiscal 2011 results primarily from the addition of the Bioline Group to our Life Science segment in July 2010. Sales from our focus families (C. difficile, Foodborne and H. pylori) comprised 62% of our Diagnostics segments’ revenues during fiscal 2012.

The overall revenue change for our Diagnostics segments during fiscal 2012 was an increase of 8%, reflecting growth in all of our focus product families – 7% growth in our H. pylori products, 13% growth in our foodborne products and 21% growth in our C. difficile products. Excluding the effects of currency translation, sales of our European Diagnostics segment increased by 2% in fiscal 2012, reflecting the combined effects of increases in our C. difficile and H. pylori product families, partially offset by a decline in the sales of our foodborne and respiratory products.

C. difficile Products

Our illumigene^® molecular C. difficile product has now been available in markets around the world for over two years. Sales of this product were approximately $22,000 and $9,000 in fiscal 2012 and fiscal 2011, respectively. Approximately 950 clinical laboratories are current customers using our illumigene^® platform, which now includes three tests (see below for a discussion of our second and third tests for Group B and Group A Strep). While the majority of these customers have adopted the C. difficile assay, a growing number of customers are purchasing multiple assays for the platform. Our illumigene^® molecular C. difficile product has restored the C. difficile product family to positive sales growth, 21% and 10% in fiscal 2012 and fiscal 2011, respectively.

Our major competitors in this product family are Cepheid and Becton Dickinson (molecular) and Alere (immunoassay). We believe that we have two principal advantages versus our competition. First, our molecular instrumentation package has a smaller footprint and significantly lower cost than either Cepheid or Becton Dickinson. We believe that this advantage allows our product to fit into virtually any size hospital or reference laboratory. We believe that our second principal advantage is the breadth of our C. difficile product offerings. With the launch of our molecular product and FDA clearance of our common antigen C. difficile products – Premier C. difficile GDH received FDA clearance in May 2011, and ImmunoCard C. difficile GDH received FDA clearance in December 2011 – we believe we are in a unique position to offer a full line of testing solutions to our clinical laboratory customers around the world to counter the competitive pressures surrounding this market. Additionally, we hold the only FDA-approved claim for C. difficile testing in the pediatric population. These advantages, along with the performance features of the products in our C. difficile portfolio, give us a compelling product offering for any hospital testing method preference.

During fiscal 2012, we received FDA clearance for our second and third molecular tests for the illumigene^® molecular platform – illumigene^® GBS (Group B Streptococcus) in December 2011 and illumigene^® Group A Strep (Group A Streptococcus) in September 2012. As alluded to above, over 100 customers are now purchasing two assays for the illumigene^® platform – the majority being C. difficile and GBS – with revenue generated by our GBS test approximating $1,100 during fiscal 2012. In addition, with the recent introduction of our Group A Strep test, there are a growing number of customers adopting all three of our molecular-platform assays. A test for Mycoplasma pneumoniae (Walking Pneumonia) was recently submitted to the FDA for marketing clearance and is expected to be available for sale in the U.S. during the second quarter of fiscal 2013. Our fifth test on the illumigene^® platform is for Bordetella pertussis (Whooping Cough), which is expected to be available for sale in the U.S. during the third or fourth quarter of fiscal 2013. Our development pipeline for illumigene^® also includes two sexually-transmitted disease assays, expected to be available for sale in the U.S. during the first half of fiscal 2014.

In addition to Cepheid, Becton Dickinson and Alere, other competitors are beginning to enter the C. difficile market. Quest Diagnostics and Great Basin recently received FDA clearance for a molecular C. difficile test and Quidel received CE marking approval for a molecular C. difficile test for sale within the European Union. Although we believe that the breadth of our C. difficile product offerings and our low cost molecular platform provide key advantages to the offerings of our competitors, selling prices may come under pressure as more competitors enter the market.

Foodborne Products

Although our foodborne products are marketed and sold on a global basis, most of our sales volume is within the U.S. Diagnostics segment. We continue to see demand increases in the United States, as laboratories realize the benefits of increased sensitivity and faster turnaround time with our tests for Enterohemorrhagic E. coli (EHEC) and Campylobacter, compared to traditional culture methods. Sales increases for these products within the U.S. Diagnostics segment were 15% and 35% during fiscal 2012 and fiscal 2011, respectively. The market acceptance and volume growth of these products has resulted in annual global revenues for this disease family surpassing the $20,000 mark.

We believe that the primary competition for our foodborne products is laboratory culture methods. We believe that our products have two principal advantages versus culture methods. The first principal advantage is test accuracy. Independent evaluations have shown our products to have higher sensitivity than culture methods. The second principal advantage is improved work flow of the testing process, resulting in a significantly shortened time to test result. Our single-use rapid products provide a test result in approximately 20 minutes, whereas culture results can take up to 24-48 hours. Time to test result can be a critical factor in the physician’s choice of therapies.

H. pylori Products

During fiscal 2012, sales of our H. pylori products grew 11% for our U.S. Diagnostics segment and increased 3% for our European Diagnostics segment on an organic basis, compared to the year-over-year sales activity these segments experienced in 2011 of 14% growth and 3% decline, respectively. The increase for our U.S. Diagnostics segment continues to reflect the benefits of our partnerships with managed care companies in promoting the health and economic benefits of a test and treat strategy, and the ongoing effects of such strategy moving physician behavior away from serology-based testing toward direct antigen testing. We continue to expect that our efforts with managed care companies in the U.S. will provide low to mid-teens growth opportunities for the next several years. The sales results for our European Diagnostics segment reflect the ongoing impact of pricing pressures from competitive products in European markets.

Respiratory Products

During fiscal 2012, respiratory sales for our Diagnostics segments decreased 3% compared to fiscal 2011, following a 26% year-over-year decrease from fiscal 2010 to fiscal 2011. The dramatic sales fluctuation for this family in recent years is a direct result of the end of the novel A (H1N1) outbreak late in the fiscal 2010 first quarter. Total non-influenza respiratory product sales remained relatively flat compared to fiscal 2011, with sales of such products increasing 4% for our U.S. Diagnostics segment and decreasing 18% for our European Diagnostics segment on an organic basis. At present, we do not expect significant revenue increases from influenza products in fiscal 2013 and expect annual influenza product revenues to be approximately $2,500 to $3,000, consistent with the last two fiscal years.

Group Purchasing Organizations and Integrated Delivery Networks

In our U.S. Diagnostics segment, consolidation of the U.S. healthcare industry over the last several years has led to the creation of group purchasing organizations (GPOs) and integrated delivery networks (IDNs) that aggregate buying power for hospital groups and put pressure on our selling prices. We have multi-year supply agreements with several GPOs and IDNs.

Life Science Segment

Sales for our Life Science segment increased 11% in fiscal 2012, reflecting increases in both our core bulk reagent business (8%) and our molecular reagent business (15%). The year-over-year increase in the core bulk reagent business largely results from increased orders for Rubella and Hepatitis A proteins. Our molecular reagent business, operated through our Bioline Group, continues to benefit from its new product launches and advancements during recent months – most notably its new SensiFAST™ and MyTaq™ PCR components. Revenues for our Life Science segment are inherently dependent upon customer order patterns and timing of contract manufacturing work. For fiscal 2013, we expect overall revenue growth of our Life Science segment to be in the range of 5% to 6%, led by the Bioline Group, which we expect to generate double-digit increases in sales of its molecular reagent products. We expect sales of our bulk antigen, antibody and reagent products to decline slightly in fiscal 2013 due to a slowing immunoassay demand profile. While we are seeing opportunities in China for our bulk antigen, antibody and reagent products, it will likely take the next year to generate actual revenue.

As a result of the order volume trends in bulk antigens, antibodies and reagents, during the fourth quarter of fiscal 2011, we announced the closure of our Saco, Maine facility, and completed the consolidation of manufacturing operations into our Memphis, Tennessee facility during the second fiscal quarter of 2012. Total costs to complete the consolidation of facilities approximated $2,100, consisting of fixed asset impairments, inventory impairments, stay bonuses and moving costs, among other similar items. During the fourth quarter of 2011, we recognized approximately $1,100 of these costs, and recognized the remaining $1,000 during the first three quarters of fiscal 2012.

Foreign Currency

During fiscal 2012, currency exchange rates had an approximate $1,700 unfavorable impact on revenue; $1,450 within the European Diagnostics segment and $250 in the Life Science segment. This compares to currency exchange having an approximate $600 favorable impact on revenue in fiscal 2011.

- 31 -

Table of Contents

The volatility in the Euro-USD exchange rate increased significantly during the last half of the fiscal year, and this may continue into the foreseeable future until such time as the sovereign debt crisis situation in Europe is resolved. Each one-point decline in the Euro-USD exchange rate (e.g., 1.30 to 1.29) negatively affects the revenues of our European Diagnostics segment by approximately $160. However, we would not expect such exchange rate fluctuations to have a significant impact on operating income. This results from the fact that we are also exposed to foreign currency risk related to the supply of certain European-manufactured diagnostic test kits, which serves to provide a natural hedge against the impact on European Diagnostics revenue.

Significant Customers

Our U.S. Diagnostic segment’s sales through two national distributors were 49% of the U.S. Diagnostics segment’s total sales for both fiscal 2012 and fiscal 2011, or 30% of consolidated sales, for both fiscal 2012 and fiscal 2011.

Our Life Science segment’s sales of purified antigens and reagents to two diagnostic manufacturing customers were 19% of the Life Science segment’s total sales for fiscal 2012 or 5% of our consolidated sales for fiscal 2012, compared to 15% and 4% of fiscal 2011 Life Science segment and consolidated sales, respectively.

Segment Revenues:

Our reportable segments are U.S. Diagnostics, European Diagnostics and Life Science. The U.S. Diagnostics segment consists of manufacturing operations in Cincinnati, Ohio, and the sale and distribution of diagnostic test kits in the U.S. and countries outside of Australia, Europe, Africa and the Middle East. The European Diagnostics segment consists of the sale and distribution of diagnostic test kits in Australia, Europe, Africa and the Middle East. The Life Science segment consists of manufacturing operations in Memphis, Tennessee; Boca Raton, Florida; London, England; Luckenwalde, Germany; and Sydney, Australia, and the sale and distribution of bulk antigens, antibodies, PCR/qPCR reagents, nucleotides, competent cells and bioresearch reagents domestically and abroad. The Life Science 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 segments, in the normal course of business, may be affected by buying patterns of major distributors, seasonality and strength of certain diseases, and foreign currency exchange rates. Revenues for the Life Science segment, in the normal course of business, may be affected 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. We believe that the overall breadth of our product lines serves to reduce the variability in consolidated revenues.

- 32 -

Table of Contents

Revenues for each of our segments are shown below.

Gross Profit:

The improvement in our overall gross profit margins from 2010 to 2012 reflects the combined effects of 1) the margin contribution of Bioline Group products; 2) continued operating efficiencies in our Cincinnati, Ohio diagnostic test manufacturing facility; 3) consolidation of our Maine facility into our Tennessee facility; and 4) the year-over-year declines in respiratory product sales. Our respiratory product family generally has a lower gross profit margin than our focus product families (C. difficile, H. pylori and foodborne). Sales of respiratory products during fiscal 2012, 2011 and 2010 were approximately 9%, 10% and 15%, respectively, of our consolidated sales. Specifically, sales of the Company’s influenza products during fiscal 2012, 2011 and 2010 represented approximately 1%, 2% and 6%, respectively, of consolidated sales.

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:

Overall, the relative stability in total operating expense during fiscal 2012 and the increase in fiscal 2011 result in large part from the combined effects of our (i) fiscal 2012 efforts to control spending in each of our segments while investing the necessary resources in our strategic areas of growth; (ii) beginning to realize cost savings during 2012 from the consolidation of our Core Life Science operations into one facility; (iii) incurring costs in connection with the consolidation of our Saco, Maine operations into our Memphis, Tennessee location of approximately $1,013 during fiscal 2012, and approximately $1,057 during fiscal 2011 ($548 of an Operating Expense nature); (iv) incurring during the second quarter of fiscal 2011 approximately $1,240 of costs in connection with the reorganization of our European and Global Sales and Marketing Leadership; and (v) realizing the impact on all three operating expense categories (i.e., Research & Development, Selling & Marketing, and General & Administrative) during fiscal 2011 of adding the Bioline Group’s full-year operating expenses.

Operating expenses for the U.S. Diagnostics segment increased $1,650 for fiscal 2012 compared to fiscal 2011, and increased $2,628 for fiscal 2011 compared to fiscal 2010. These overall increases result largely from the combined effects of the following:

- 34 -

Table of Contents

Fiscal 2012

Research & Development

Overall increase in spending on new product development activities, related primarily to our illumigene^® platform-based test for Group A Streptococcus, including an approximate $350 increase in personnel-related costs.

Selling & Marketing

Field sales force realignment activities during the year resulting in decreased sales commission expenses of approximately $1,050.

General & Administrative

Improved corporate-wide operating results resulting in increased bonus, profit sharing and deferred compensation expenses of approximately $2,800, partially offset by an approximate $650 decrease in stock-based compensation during fiscal 2012.

Fiscal 2011

Research & Development

Overall increase in spending on new product development activities related to products submitted to the FDA during the year and planned for submission during fiscal 2012, as well as spending on increased illumigene^® component qualification activities. Costs include increased personnel-related and quality control costs of approximately $450 and $150, respectively.

Selling & Marketing

The launch of illumigene^® resulting in increased sales commissions expenses and increased travel and trade show expenses of approximately $750 and $300, respectively.

General & Administrative

The positive effects of overall cost containment and reduction efforts being offset by an approximate $750 increase in stock-based compensation during fiscal 2011.

Operating expenses for the European Diagnostics segment decreased $270 for fiscal 2012 compared to fiscal 2011, and increased $1,174 for fiscal 2011 compared to fiscal 2010. The 2012 decrease primarily reflects the effect of the aforementioned reorganization of our sales and marketing leadership during the fiscal 2011 second quarter being partially offset by increased costs of additional management personnel. The fiscal 2011 increase was primarily attributable to costs associated with the sales and marketing leadership reorganization during the fiscal 2011 second quarter.

- 35 -

Table of Contents

Operating expenses for the Life Science segment decreased $63 for fiscal 2012 compared to fiscal 2011, and increased $9,145 for fiscal 2011 compared to fiscal 2010, excluding the effect of one-time transaction costs of $1,240 in fiscal 2010. The decrease in 2012 primarily results from (1) realizing cost savings from the Maine-Tennessee facility consolidation, and (2) an increased investment in Bioline Group sales resources. The increase in 2011 resulted from the addition of the Bioline Group’s full-year operating expenses and the costs related to consolidating the Maine and Tennessee facilities.

The amount of stock-based compensation expense reported for fiscal 2012, 2011 and 2010 was $1,987, $2,614 and $1,866, respectively. In November 2009, we granted restricted shares and restricted share units to certain employees, with half of each employee’s grant being time-vested restricted shares or restricted share units vesting in total in four years, and the remaining half being subject to attainment of a specified earnings target for fiscal 2010. Dividend equivalents were paid on these shares and units throughout fiscal 2010. While the fiscal 2010 earnings target was not met, on September 30, 2010, the Compensation Committee of the Board of Directors chose to convert the performance-based restricted shares to time-vested restricted shares vesting in total after four years in recognition of the achievement in fiscal 2010 of several strategic initiatives. Expense totaling $472 was recorded in fiscal 2010 as a result of this conversion, and is included in the total amount of stock-based compensation set forth above.

During November 2010, we granted restricted shares and restricted share units to certain employees, with half of each employee’s grant being time-vested restricted shares or restricted share units vesting in full in four years, and the remaining half being subject to attainment of a specified earnings target for fiscal 2011. Although dividend equivalents were paid on these shares and units throughout fiscal 2011, because Meridian’s fiscal net earnings did not reach the minimum level in 2011, the performance-based awards were not earned and no stock-based compensation has been recorded for these performance-based awards.

Similar to previous years, during fiscal 2012, we granted restricted share units to certain employees, with half of each employee’s grant being time-vested restricted share units vesting in total on the fourth anniversary of the grant date, and the remaining half being subject to attainment of a specified earnings target for fiscal 2012. While dividend equivalents were paid on these units throughout fiscal 2012, the target for fiscal 2012 was not met and the performance-based portion of the restricted share units granted during fiscal 2012 has been cancelled. Additionally, during fiscal 2012, we granted restricted share units and options to certain executive management employees to reward them for meeting Company revenue targets in advance of planned expectations. These awards can only be earned if specified cumulative revenue thresholds are met one fiscal quarter in advance of planned revenue expectations through fiscal 2015, with the three measurement dates for ratably earning one-third of the grant being (i) the 21-month period ending June 30, 2013, (ii) the 33-month period ending June 30, 2014 and (iii) the 45-month period ending June 30, 2015. To date, no expense has been recognized for these restricted share units and options.

Operating Income

Operating income increased 23% and decreased 3% in fiscal 2012 and fiscal 2011, respectively, as a result of the factors discussed above.

Other Income and Expense

Interest income was $42, $115 and $124, for fiscal 2012, 2011 and 2010, respectively. The decreases during the periods reflect (i) lower interest yields in the current interest rate environment, (ii) the use of cash early in the fiscal 2010 fourth quarter to acquire the Bioline Group, and (iii) the use of cash in fiscal 2011 to fund facility expansions in Cincinnati and Memphis, and to build illumigene^® inventory. The increased level of other income during fiscal 2012 reflects an approximate $160 increase in net currency gains, partially offset by an approximate $100 decrease in the Bioline Group’s grant income from a foreign government. During fiscal 2011, the higher level of other income, net, can primarily be attributed to the addition of the Bioline Group, as it contributed grant income from a foreign government agency of approximately $200. As noted, the level of grant income significantly decreased in fiscal 2012 and is not expected to continue at a significant level, if at all, in fiscal 2013 due to the local country’s rules regarding ownership by a U.S. parent.

Income Taxes

The effective rate for income taxes was 33%, 34% and 36% for fiscal 2012, 2011 and 2010, respectively. The decrease in the effective tax rate for fiscal 2012 primarily resulted from the net tax benefit on dividends from a foreign-based subsidiary, while the decrease in the effective tax rate for fiscal 2011 was primarily attributable to the release of certain reserves for uncertain tax positions due to the passage of the relevant statutes of limitations and the nondeductible nature of Bioline acquisition costs.

Impact of Inflation

To the extent feasible, we have consistently followed the practice of adjusting our prices to reflect the impact of inflation on salaries and fringe benefits for employees and the cost of purchased materials and services. Inflation and changing prices did not have a material adverse impact on our gross margin, revenue or operating income in fiscal 2012, 2011 and 2010.

Liquidity and Capital Resources:

Comparative Cash Flow Analysis

Our cash flow and financing requirements are determined by analyses of operating and capital spending budgets, consideration of acquisition plans, and consideration of common share dividends. We have historically maintained a credit facility to augment working capital requirements and to respond quickly to acquisition opportunities. Our investment portfolio presently consists of overnight repurchase agreements.

- 37 -

Table of Contents

We have an investment policy that guides the holdings of our investment portfolio. Our objectives in managing the investment portfolio are to (i) preserve capital, (ii) provide sufficient liquidity to meet working capital requirements and fund strategic objectives such as acquisitions, and (iii) capture a market rate of return commensurate with market conditions and our policy’s investment eligibility criteria. As we look forward, we will continue to manage the holdings of our investment portfolio with preservation of capital being the primary objective.

At the present time, we do not expect current conditions in the financial markets, or overall economic conditions to have a significant impact on our liquidity needs, financial condition, or results of operations, although no assurances can be made in this regard. We intend to continue to fund our working capital requirements and dividends from current cash flows from operating activities and cash on hand. If needed, we also have an additional source of liquidity through our $30,000 bank credit facility. Approximately, $4,600 of our accounts receivable at September 30, 2012 is due from Italian hospital customers whose funding ultimately comes from the Italian government. During the fourth quarter of fiscal 2011 and first quarter of fiscal 2012, we experienced a deterioration in the aging of our Italian accounts receivable. While such aging appeared to stabilize during fiscal 2012, we continue to monitor such accounts closely. Our liquidity needs may change if overall economic conditions worsen and/or liquidity and credit within the financial markets remains tight for an extended period of time, and such conditions impact the collectibility of our customer accounts receivable or impact credit terms with our vendors, or disrupt the supply of raw materials and services.

Fluctuations in overall stock market valuations may raise questions as to the potential impairment of goodwill and other long-lived assets. Our annual goodwill impairment review takes place as of June 30^th each year. There have been no impairments from these annual reviews. As of October 31, 2012, our stock price was $19.75 per share, compared to our book value per share of $3.46 as of September 30, 2012. This relationship, stock price trading at a 5.7x multiple of book value, is an indicator that the fluctuation in overall stock market valuations and its impact on our stock price has not been a triggering event for impairment of our goodwill and other long-lived assets.

Net cash provided by operating activities increased 89% to $42,446 in fiscal 2012 reflecting the 24% increase in net earnings and the effects of net working capital changes related to our investments in illumigene^® inventory, including readers, and the timing of payments from customers and payments to suppliers.

Net cash used for investing activities was $4,435 for fiscal 2012 compared to $9,151 for fiscal 2011. This decrease in cash used primarily results from an approximate $5,600 decrease in expenditures for property, plant and equipment compared to fiscal 2011, which included significant facility expansions in both Cincinnati and Memphis.

- 38 -

Table of Contents

Net cash used for financing activities was $30,674 for fiscal 2012 compared to $27,520 for fiscal 2011. This increase was attributable to the combined effects of a 1% increase in dividend payments and an approximate $2,900 decrease in proceeds and tax benefits from the exercise of stock options.

Net cash flows from operating activities and cash on hand are anticipated to be adequate to fund working capital requirements, capital expenditures and dividends during the next twelve months. During the last two quarters of fiscal 2012, as well as for the full fiscal year, the per share amount of our cash dividend was lower than our diluted earnings per share, nearly in line with our long-standing policy of establishing a dividend payout ratio between 75% and 85% of diluted earnings per share. During fiscal 2013, we believe that this positive dividend payout relationship will continue, although no assurances can be made in this regard. During fiscal 2012, cash generated from the Company’s operating activities exceeded the quarterly dividend by 36%.

Capital Resources

We have a $30,000 credit facility with a commercial bank which expires September 15, 2015. As of November 23, 2012, there were no borrowings outstanding on this facility and we had 100% borrowing capacity available to us. We have had no borrowings outstanding under this facility during fiscal 2012 or fiscal 2011.

Our capital expenditures are estimated to range between approximately $3,500 to $5,000 for fiscal 2013, with the actual amount depending upon actual operating results and the phasing of certain projects. Such expenditures may be funded with cash and equivalents on hand, operating cash flows, and/or availability under the $30,000 credit facility discussed above.

Medical Device Tax

Included within the U.S. government’s comprehensive healthcare reform legislation, enacted during 2010, was the establishment of a 2.3% excise tax on the sales of medical devices beginning in calendar 2013. We currently anticipate that this legislation will result in an excise tax for our company of approximately $2,000 in fiscal 2013. At the present time it is believed that little, if any, of this cost can be passed on to customers.

Known Contractual Obligations:

Known contractual obligations and their related due dates were as follows as of September 30, 2012:

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 14%). Meridian expects that payments under these agreements will amount to approximately $3,500 in fiscal 2013. These royalty payments primarily relate to the U.S. Diagnostics segment.

Meridian entered into a license agreement in October 2006 with a third party that provides rights to a molecular technology for infectious disease testing in the United States, Europe and other geographic markets. The agreement, as amended, calls for remaining payments of up to approximately $2,050, based on the achievement of certain product development milestones and on-going royalties once products are available for commercial sale.

Off-balance sheet arrangements

Except for the operating lease arrangements noted above, we have no off-balance sheet arrangements.

Market Risk Exposure:

Foreign Currency Risk

We have market risk exposure related to foreign currency transactions. We are exposed to foreign currency risk related to our European distribution operations where the billing currency is the Euro for most of our customers in these markets. We also are exposed to foreign currency risk related to the supply of certain diagnostic test kits by manufacturers located in Germany and Spain. These foreign currency risks are opposite one another, providing a natural hedge with respect to consolidated gross profit and operating income. Additionally, as a result of the July 2010 Bioline Group acquisition, we are exposed to foreign currency risks related to the Bioline Group’s operations in Australia (Australian dollar), Germany (Euro), and the U.K. (British pound). Assessing foreign currency exposures is a component of our overall ongoing risk management process, with such currency risks managed as we believe appropriate.

Concentration of Customers/Products Risk

Our U.S. Diagnostic segment’s sales through two national distributors were 49% of the U.S. Diagnostics segment’s total sales or 30% of consolidated sales for fiscal 2012. Our C. difficile, foodborne and H. pylori product families accounted for 62% of our U.S. Diagnostics segment’s third-party sales during fiscal 2012. These same products accounted for 59% of our European Diagnostics segment’s third-party sales and 47% of our consolidated sales for fiscal 2012.

Our Life Science segment’s sales of purified antigens and reagents to two diagnostics manufacturing customers were 19% of the Life Science segment’s total sales for fiscal 2012 or 5% of our consolidated sales for fiscal 2012. Our Life Science segment has four other significant customers who purchase antigens, antibodies and reagents, which together comprise 9% of the segment’s total sales for fiscal 2012.

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 from sales when product is shipped and title has passed to the buyer. Revenue for the U.S. Diagnostics segment is reduced at the date of sale for product price adjustments due certain distributors under local contracts designed to reimburse such distributors for their cost in handling our products. Management estimates accruals for distributor price adjustments based on local contract terms, sales data provided by distributors, estimates of inventories of our products held by distributors, historical statistics, current trends, and other factors. Changes to the accruals are recorded in the period that they become known.

Revenue for our Diagnostics segments includes bundled product revenue for our illumigene^® molecular test system. The bundled product includes an instrument, instrument accessories and test kits. If not sold outright, amounts invoiced for the illumigene^® test kits cover the instrument, accessories and test kits. Revenue is recognized based on test kit sales. If not sold outright, costs for the instruments are recognized in cost of sales over the expected instrument utilization period, generally three years.

Life Science revenue for contract services may come from research and development services or manufacturing services, including process development work, or a combination of both. Revenue is recognized based on each of the deliverables in a given arrangement having distinct and separate customer pricing. Pricing is often subject to 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 generally recognized upon delivery of product and acceptance by the customer. In some cases, customers may request that we store on their behalf, clinical grade biologicals that we produce under contract manufacturing agreements. These cases arise when customers do not have clinical grade storage facilities or do not want to risk contamination during transport. For such cases, revenue may be recognized on a bill-and-hold basis. No such bill-and-hold arrangements existed at September 30, 2012 or September 30, 2011.

Inventories

Our inventories are carried at the lower of cost or market. Cost is determined on a first-in, first-out (FIFO) basis for substantially all of our inventories. 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. 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.

Goodwill is 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 these analyses.

Identifiable intangibles with finite lives are subject to impairment testing. 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. There were no events or circumstances in fiscal 2012, 2011 or 2010 indicating that the carrying value of 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. Management is required 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, 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.

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 purposes 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 non-U.S. subsidiaries are considered by management to be permanently re-invested in such subsidiaries. Consequently, U.S. deferred tax liabilities on such earnings have not been recorded. We believe that such U.S. taxes would be largely offset by foreign tax credits for taxes paid locally.

From time to time, our tax returns in federal, state and foreign jurisdictions are examined by the applicable tax authorities. To the extent that adjustments result from the completion of these examinations or the lapsing 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 operations.

Recent Accounting Pronouncements:

In May 2011, FASB issued Accounting Standards Update (ASU) No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. FASB ASU No. 2011-04 amends and clarifies the measurement and disclosure requirements of FASB ASC 820, resulting in common requirements for measuring fair value and for disclosing information about fair value measurements, clarification of how to apply existing fair value measurement and disclosure requirements, and changes to certain principles and requirements for measuring fair value and disclosing information about fair value measurements. The new requirements were effective for fiscal years beginning after December 15, 2011. The Company’s adoption of this amended guidance on October 1, 2012 had no material impact on the Company’s consolidated results of operations, cash flows or financial position.

In June 2011, FASB issued ASU No. 2011-05, Presentation of Comprehensive Income, which amends the disclosure and presentation requirements of Comprehensive Income. Specifically, FASB ASU No. 2011-05 requires that all nonowner changes in shareholders’ equity be presented either in 1) a single continuous statement of comprehensive income or 2) two separate but consecutive statements, in which the first statement presents total net income and its components, and the second statement presents total other comprehensive income and its components. These new presentation requirements, as currently set forth, are effective for the Company as of October 1, 2012 and will impact financial statement presentation, but will not impact the Company’s consolidated results of operations, cash flows or financial position.

In September 2011, FASB issued ASU No. 2011-08, Testing Goodwill for Impairment, which amended goodwill impairment guidance to provide an option for entities to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. After assessing the totality of events and circumstances, if an entity determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, performance of the two-step impairment test is no longer required. This guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, with early adoption permitted. Adoption of this guidance in fiscal 2013 is not expected to have any impact on the Company’s consolidated results of operations, cash flow or financial position.

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 of 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, 2012.

The company’s independent registered public accounting firm has issued an attestation report on the registrant’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders

Meridian Bioscience, Inc.

We have audited the accompanying consolidated balance sheets of Meridian Bioscience, Inc. (an Ohio corporation) and subsidiaries as of September 30, 2012 and 2011, and the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the three years in the period ended September 30, 2012. Our audits of the basic financial statements included the financial statement schedule listed in the index appearing under Schedule No. II. We also have audited Meridian Bioscience, Inc.’s internal control over financial reporting as of September 30, 2012, 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 and financial statement schedule, 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 financial statement schedule 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 consolidated financial statements referred to above present fairly, in all material respects, the financial position of Meridian Bioscience, Inc. and Subsidiaries as of September 30, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended September 30, 2012 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

In our opinion, Meridian Bioscience, Inc. and subsidiaries, maintained, in all material respects, effective internal control over financial reporting as of September 30, 2012, based on criteria established in Internal Control—Integrated Framework issued by COSO.
