History

Founding and Early Years

Neogen Corporation was founded in June 1982 as a spin-off initiative supported by investments from Michigan State University (MSU) to advance biotechnology development in Lansing, Michigan.^[5] Senior officials at MSU approached Herbert D. "Ted" Doan, a former CEO of Dow Chemical Company who was managing a venture capital fund focused on mid-American investments, with a vision to commercialize emerging biotechnologies from university research into an entrepreneurial enterprise.^[5] Doan endorsed the concept and recruited businessman James L. Herbert to serve as the company's first CEO, leading to the official establishment of Neogen that same month.^[5] Willis A. Wood, a professor and former chair of the biochemistry department at MSU, played a pivotal role as an early investor and promoter, leveraging his university connections to support the venture; he also served as Neogen's first president.^[6] The company's initial operations were headquartered in Lansing, Michigan, where it began developing diagnostic test kits to identify contaminants in food and animal products.^[7] From its inception, Neogen focused on biotechnology applications for agriculture and food safety, with its first significant product line consisting of rapid immunoassay test kits for detecting drug residues in animal products and meat.^[8] These early launches in the 1980s targeted essential testing needs in the agricultural sector, establishing the foundation for Neogen's expertise in residue detection to ensure product integrity and safety.^[8]

Key Acquisitions and Expansions

Neogen's expansion strategy from the late 1980s onward relied heavily on targeted acquisitions to diversify and strengthen its product portfolio in animal and food safety. In 1985, the company acquired Ideal Instruments Inc., a manufacturer of veterinary instruments and drug delivery tools, which broadened Neogen's offerings in animal health applications such as syringes and applicators for livestock management.^[9] This move marked Neogen's initial foray into external growth, complementing its foundational focus on diagnostic testing.^[5] Subsequent acquisitions further enhanced Neogen's detection and biosecurity capabilities. In 1992, Neogen purchased WTT, Incorporated, a firm specializing in immunoassay technologies, which introduced comprehensive drug residue testing kits capable of detecting over 300 substances in animal agriculture, including therapeutic drugs and contaminants in meat and dairy products.^[10] By 2010, the acquisition of GeneSeek, Inc., a prominent agricultural genomics laboratory in Lincoln, Nebraska, for $13.8 million, significantly advanced Neogen's expertise in genetic testing for animal breeding, health monitoring, and trait selection.^[11] This integration allowed Neogen to offer advanced genomic services, such as parentage verification and disease resistance profiling, to livestock producers worldwide.^[12] In 2014, Neogen acquired Chem-Tech Ltd., an Iowa-based manufacturer of insecticides and disinfectants, for approximately $17.2 million, incorporating biosecurity products like rodenticides and surface sanitizers into its animal health segment to address farm hygiene and pest control needs.^[13] These acquisitions collectively expanded Neogen's technological reach and market segments without overlapping its core testing operations. Neogen's international growth paralleled these domestic expansions, beginning with early market entry in Asia and solidifying through subsidiary establishments. The company entered the Chinese market around 2009 through partnerships focused on food safety research, later formalizing its presence with a Shanghai consulting office in 2012 that evolved into a full trading subsidiary by 2013 to support direct sales and regulatory compliance efforts.^[14] By the mid-2010s, Neogen's product lineup had grown to over 100 immunoassay test kits for detecting pathogens, toxins, and drug residues, distributed globally.^[15] Operations expanded to include subsidiaries in Canada, the United Kingdom (via Neogen Europe Ltd.), broader Europe, Mexico (Neogen Latinoamerica), Brazil (Neogen do Brasil), and India (following the 2015 acquisition of Sterling Test House laboratory), enabling localized support for food and animal safety solutions across these regions.^[16]

Major Merger and Recent Developments

In December 2021, Neogen announced a merger with 3M's Food Safety business, valued at an enterprise value of approximately $5.3 billion, which included the integration of 3M's Petrifilm plates and an expansion of Neogen's diagnostic test kit portfolio for detecting foodborne pathogens and allergens.^[17] The transaction was completed on September 1, 2022, positioning Neogen as a leading global provider in food and animal safety solutions by combining complementary technologies and market reach.^[18] Neogen reported fiscal 2022 revenues of $527.16 million, reflecting a 13% increase from the prior year, driven by organic growth in its Food Safety and Animal Safety segments.^[19] Operating income for the same period reached $58.62 million, or 11.1% of sales, though this figure was impacted by $25.6 million in merger-related costs.^[20] These results underscored initial synergies but also highlighted integration challenges that would persist. As of November 30, 2024, Neogen identified material weaknesses in its internal controls over financial reporting, particularly related to period-end invoice accruals and information technology general controls, which necessitated restatements of prior financial statements to ensure completeness and accuracy.^[21] These deficiencies stemmed from complexities in post-merger systems and processes, prompting remediation efforts including enhanced review controls and IT upgrades.^[22] In April 2025, Neogen announced the sale of its global Cleaners and Disinfectants business to Kersia Group for $130 million in cash, as part of a strategic focus on core food and animal safety operations; the transaction was completed on July 18, 2025.^[23]^[24] In the fourth quarter of fiscal 2025, Neogen's revenues declined 4.8% to $225.5 million from $236.8 million in the prior year, primarily due to ongoing integration issues from the 3M merger, including production inefficiencies in sample collection and elevated inventory adjustments.^[25] This downturn reflected broader pressures on the Food Safety segment amid softer market conditions and unresolved operational hurdles.^[26] On August 11, 2025, Neogen appointed Mike Nassif as CEO and President, succeeding John Adent, who stepped down after eight years amid the company's performance challenges and integration difficulties.^[27] Nassif, formerly Global President of Siemens Healthineers' Varian Oncology business, was tasked with driving strategic stabilization and growth in the evolving post-merger landscape.^[28] In the first quarter of fiscal 2026, ended August 31, 2025, Neogen reported revenues of $209.2 million, a decrease of 3.6% from $217.0 million in the prior-year quarter, though core revenues increased 0.3%; net income was $36.3 million.^[29] The company also implemented restructuring actions in September 2025, including headcount reductions, to align costs with its strategic priorities, and reaffirmed its FY2026 guidance of $820–$840 million in revenue. On November 14, 2025, S&P Global Ratings lowered Neogen's credit rating to 'B+' from 'BB-', citing elevated integration costs from the 3M merger, divestiture-related expenses, and expected cash flow pressures through fiscal 2026.^[30]

Neogen's Animal Safety segment provides a range of products and services designed to safeguard animal health, particularly in livestock and companion animals, through diagnostics, pharmaceuticals, and biosecurity measures. This includes veterinary instruments, drug residue testing, and therapeutics that support disease prevention and regulatory compliance in industries such as dairy and poultry production.^[40] Following its 1985 acquisition of Ideal Instruments, Neogen expanded its portfolio to include a comprehensive line of veterinary instruments essential for animal care and drug administration. These products feature disposable syringes and combos in premium hard packs, ultra-sharp needles with aluminum hubs for durability in large animal applications, and digital thermometers for accurate temperature monitoring in species like horses and cattle. Such tools are widely used in beef, dairy, and swine operations to ensure precise and hygienic delivery of treatments.^[41]^[42]^[43] Neogen offers drug residue test kits that screen for over 300 substances, including antibiotics, performance-enhancing drugs, and their metabolites, in samples like meat, milk, and urine to ensure compliance with food safety regulations. These ELISA-based assays provide rapid, qualitative detection for toxicology applications in racing and food-producing animals, helping producers avoid violations and maintain market access. For instance, the kits are instrumental in dairy and poultry sectors where residue monitoring prevents contamination in animal-derived products.^[44]^[45] Through the 2014 acquisition of Chem-Tech Ltd., Neogen bolstered its biosecurity offerings with insecticides tailored for animal and farm environments, such as the Prozap line for controlling pests in livestock facilities. Complementing these are disinfectants like Synergize, a quaternary ammonium/glutaraldehyde-based cleaner effective against viruses, bacteria, and fungi on farm surfaces, equipment, and footwear. These products form a critical part of biosecurity programs in dairy and poultry operations, reducing pathogen transmission and supporting overall herd health.^[13]^[46] The segment also encompasses antibiotics and therapeutics for preventing and treating livestock diseases, with injectables and oral formulations targeting bacterial infections in cattle, swine, and poultry. Examples include broad-spectrum antibiotics for respiratory and systemic issues, often used adjunctively with immunostimulants like EqStim for equine applications, integrated into Neogen's Animal Safety offerings to enhance disease management. These solutions are particularly vital in high-density animal protein industries, where timely intervention minimizes economic losses from outbreaks.^[40]^[47] For companion animals, Neogen provides diagnostics to detect pathogens such as those causing respiratory or gastrointestinal diseases in dogs, cats, and horses, alongside performance enhancers like oral supplements and wound care products. These include ELISA and PCR-based tests for rapid identification of infections, paired with therapeutics to support recovery and vitality in veterinary practices.^[48]^[49] In fiscal year 2025, the Animal Safety segment generated revenues representing 28.7% of Neogen's total, underscoring its significance in supporting tools for animal protein sectors like dairy—through udder care and residue testing—and poultry, via biosecurity and health diagnostics.^[50]^[40]

Genomics and Research Tools

Neogen's genomics division, bolstered by the 2010 acquisition of GeneSeek, Inc. for $13.8 million, specializes in genomic sequencing services tailored for breeding programs in cattle, swine, and poultry.^[12] This acquisition integrated GeneSeek's expertise in agricultural trait selection, enabling Neogen to offer high-throughput DNA analysis that supports selective breeding for enhanced herd performance and genetic diversity.^[51] Through GeneSeek, Neogen processes samples to generate genomic profiles that inform breeding decisions, with operations centered in Lincoln, Nebraska, and expanded globally via subsequent lab acquisitions.^[52] The company provides DNA-based tests targeting key animal traits, including disease resistance, milk production, and feed efficiency. For dairy cattle, Neogen's Igenity Dairy Breeding Stock Traits panel evaluates causative mutations linked to production metrics such as milk yield and component levels, allowing producers to select superior genetics early in development.^[53] Similarly, the Igenity Milk Proteins test identifies variants for A2 milk production, which commands premium pricing due to its perceived digestibility benefits.^[54] In swine and poultry, genomic assays assess feed conversion efficiency and resistance to pathogens like porcine reproductive and respiratory syndrome, reducing economic losses from disease outbreaks.^[55] These tests utilize single-sample processing for multiple traits, streamlining workflows for breeders.^[56] Neogen extends its genomics capabilities to research services for universities and laboratories, offering custom genotyping arrays designed for specific scientific inquiries. These arrays, such as the GGP Bovine 100K, incorporate up to 100,000 single nucleotide polymorphisms (SNPs) selected for precision in trait mapping and population studies.^[57] Researchers can commission bespoke panels for any species or variant set, supporting projects in genetic diversity, evolutionary biology, and biomarker discovery with high-throughput output.^[52] Neogen's ISO-certified labs facilitate these services, providing data analysis tools that integrate with academic workflows for reproducible results.^[58] Genomics tools also integrate with food safety applications through traceability solutions that verify supply chain authenticity using DNA markers. Partnerships, such as with Ripe Technology, leverage blockchain to link genomic profiles of livestock to product origins, ensuring compliance and preventing fraud in premium meat and dairy markets.^[59] For instance, DNA testing confirms breed purity and geographic sourcing for poultry and beef, enhancing consumer trust and regulatory adherence.^[60] Following the 2022 merger with 3M's Food Safety Division, Neogen expanded its life sciences portfolio to include research tools supporting toxicology and allergen studies.^[50] This growth incorporates genomic sequencing services alongside immunoassay kits, such as ELISAs for detecting allergens like gluten and peanuts in research contexts, aiding investigations into exposure risks and molecular mechanisms.^[61] In toxicology, Neogen's panels analyze genetic markers for drug metabolism and toxin sensitivity, used in academic labs to model human and animal responses.^[44] These tools, now available through six global genomics labs, bridge agricultural genomics with broader life sciences applications.^[50]

Leadership and Governance

Neogen Corporation was founded in 1982 by Herbert D. "Ted" Doan and James L. Herbert as an investment project originating from Michigan State University, with Doan providing the initial vision for a biotechnology firm focused on food and animal safety solutions and approaching Herbert to serve as the company's first CEO. Herbert led Neogen as CEO from its inception through July 2017, establishing foundational governance structures that emphasized innovation and ethical business practices in the agricultural diagnostics sector, while Doan contributed to early strategic direction and served on the board of directors.^[5]^[68] In a significant leadership transition, Neogen appointed Mikhael "Mike" Nassif as CEO and President effective August 11, 2025, succeeding John Adent, with Nassif also joining the board of directors upon assuming the role. Nassif brings over two decades of global executive experience, including his tenure as Global President of Point-of-Care Diagnostics at Siemens Healthineers and senior leadership positions at AB InBev—where he drove commercial operations in the agribusiness-adjacent beverage sector—along with roles at Baxter Healthcare and Johnson & Johnson focused on business turnarounds and innovation.^[28]^[69]^[70] On October 30, 2025, Neogen announced the appointment of Bryan Riggsbee as Chief Financial Officer and Senior Vice President, effective November 3, 2025. Riggsbee, with over 25 years of experience in financial leadership in diagnostics and healthcare, succeeds the prior CFO and will oversee the global finance organization, reporting to CEO Mike Nassif.^[71] The Board of Directors, comprising 10 members divided into three staggered classes for continuity, provides strategic oversight, including on post-merger integration from the 2022 acquisition of 3M's Food Safety Division and enterprise risk management such as cybersecurity and financial reporting. The Governance Committee, in particular, monitors integration risks and succession planning, while recent board changes—including the retirement of James Tobin in May 2025, William T. Boehm's planned retirement in October 2025, and the appointment of Avi Pelossof effective October 2025—reflect efforts to refresh expertise in diagnostics and finance.^[72]^[73] Neogen maintains robust governance policies tailored to its food and animal safety operations, including a comprehensive Code of Business Conduct and Ethics that mandates anti-bribery measures, fair dealings with stakeholders, and compliance with regulations in diagnostics and biotechnology.

Controversies and Legal Issues

Securities Lawsuit

On July 18, 2025, Grant & Eisenhofer P.A. filed a federal class action securities lawsuit in the United States District Court for the Western District of Michigan against Neogen Corporation and certain executives, including former CEO John Adent and COO/CFO David Naemura, alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934.^[89] The complaint covers the class period from January 5, 2023, to June 3, 2025, and accuses the defendants of making materially false and misleading statements regarding the progress of integrating Neogen's 2022 merger with 3M's Food Safety business.^[90] Specifically, the suit claims that Neogen downplayed ongoing integration challenges, portraying the process as smoother and more successful than it actually was, which misled investors about the company's operational and financial health.^[91] Central to the allegations are Neogen's failure to disclose material weaknesses in its internal controls over financial reporting, identified as of November 30, 2024, which stemmed from integration-related inefficiencies such as chaotic systems merging and control deficiencies.^[92] These issues contributed to significant stock price declines, including a 5.4% drop to $12.36 per share on January 10, 2025, following the disclosure of a $461 million non-cash goodwill impairment charge tied to the 3M acquisition; a 28% plunge to $5.02 per share on April 9, 2025, after revealing a quarterly revenue decline partly due to integration delays; and a 17% fall to $4.96 per share on June 4, 2025, amid further adverse revelations.^[90] The lawsuit asserts that these undisclosed problems eroded investor confidence and resulted in substantial losses, with Neogen's stock declining approximately 79% over the class period, wiping out over $4 billion in market capitalization.^[93] As of November 2025, the case remains ongoing, with no lead plaintiff appointed following the September 16, 2025, deadline; multiple law firms, including Kuehn Law PLLC and Bronstein, Gewirtz & Grossman LLC, continue to investigate potential claims and encourage affected shareholders to contact them.^[94]^[95] In response, Neogen has repeatedly lowered its fiscal 2025 revenue and EBITDA guidance, acknowledged the material weaknesses in SEC filings, and undergone leadership changes, including the April 9, 2025, announcement of CEO John Adent's transition out of the role and the July 24, 2025, appointment of Mike Nassif as his successor effective August 11, 2025.^[96]^[27] Additionally, on September 15, 2025, the company disclosed a planned CFO transition, with David Naemura departing after the filing of the next quarterly report.^[97]

Integration Challenges Post-Merger

Following the 2022 merger with 3M's Food Safety Division, Neogen encountered significant operational hurdles in integrating key product lines, particularly the merging of 3M's Petrifilm production with Neogen's existing diagnostic kits. This process involved transitioning Petrifilm manufacturing in-house, which led to supply chain interruptions, SKU integration delays, and elevated backlogs due to the implementation of a new ERP system and the exit from transition service agreements in fiscal 2024. These disruptions affected production continuity and customer order fulfillment, resulting in shipment delays and some loss of market share in the short term, though supply continuity for Petrifilm was maintained for multiple quarters post-merger.^[50]^[98] Financially, the integration efforts contributed to revenue pressures, exemplified by a 4.8% decline to $225.5 million in the fourth quarter of fiscal 2025, compared to $236.8 million in the prior year. This downturn was driven by softer end-market conditions, including trade uncertainties and inflation impacting food production, compounded by integration-related costs such as $10.3 million for sample collection transitions, $1.4 million for Petrifilm duplicate startup expenses, and $0.3 million in ongoing 3M integration outlays. These factors also pressured gross margins, dropping to 41.2% for the quarter before adjustments, highlighting the challenges of market adaptation during the post-merger stabilization phase.^[26]^[99] Audits in fiscal 2024 revealed material weaknesses in Neogen's internal controls over financial reporting, including ineffective IT general controls for user access and change management, as well as deficiencies in period-end invoice accrual procedures that impacted the accuracy of accrued expenses and capital assets. These issues, identified as of May 31, 2024, stemmed from the complexities of merging financial systems and processes post-acquisition, leading to conclusions that disclosure controls were not fully effective and posing risks to reporting reliability. Remediation efforts, such as enhanced IT controls and procedural reviews, were initiated but required extended testing to ensure operational effectiveness.^[63] To address these challenges, Neogen implemented strategic adjustments, including reallocations in research and development spending to refocus on core portfolio stabilization. R&D expenses decreased to $21.09 million in fiscal 2025 from $22.48 million the prior year, reflecting reduced contracted services and employee costs in the Food Safety segment, while maintaining overall expenditures at 2-3% of revenues to prioritize high-impact areas like pathogen detection innovations. This refocusing helped mitigate integration fallout by streamlining operations and supporting the launch of products such as the rapid Listeria Right Now test. Despite short-term hurdles, these efforts positioned Neogen for long-term gains, including an expanded market presence in pathogen testing through a broadened portfolio of diagnostic tools that enhanced competitiveness against traditional and molecular platforms.^[50]^[100]
