The story

The company's history traces back to 1904, when John Townsend Baker (1860–1935) founded the chemical company J.T. Baker specializing in producing chemically pure reagents. The company gained recognition for its "Baker Analyzed" labels, which provided detailed analyses of trace impurities in its products. In 1911, the company began publishing "The Chemist-Analyst," which promoted its products and philosophy. After Baker's death in 1935, the company was acquired by Vick Chemical Company in 1941. During World War II, J.T. Baker expanded its product line to include penicillin, pesticides, and chemicals for batteries and munitions. After the war, the company further diversified into high-purity solvents, chromatography columns, and hazardous waste spill kits. In 1985, J.T. Baker and its parent company Richardson-Vicks were sold to Procter & Gamble, and subsequently sold to Mallinckrodt in 1995.

In 2010, investment firm New Mountain Capital purchased Mallinckrodt Baker Inc., which then changed its name to Avantor. The company extended its international market with the 2011 acquisitions of the Indian laboratory reagents supplier RFCL and the Polish lab supply firm POCH.

In 2016, Avantor merged with Nusil Technology. In 2017, Avantor acquired chemical blending business Puritan Products Inc. and laboratory supplies company VWR. The combined company operates under the Avantor name, with VWR and vwr.com remaining as a selling channel.

In May 2019, Avantor went public with a $3.8 billion initial public offering, which gave the company a market capitalization of $7.62 billion. As of December 2023, the top shareholders of Avantor included Vanguard Group Inc., Dodge & Cox Inc., T. Rowe Price Investment Management Inc., and BlackRock Inc.

That same year the company expanded further into Asia with the opening of an innovation center in Shanghai, which focuses on monoclonal antibodies and cell and gene therapy. In 2020, Avantor doubled the size of its Bridgewater, New Jersey innovation center, expanding its research and development capabilities and cell and gene therapy reagent manufacturing.

In 2020, Avantor began providing services and raw materials to companies manufacturing vaccines and other therapies to fight the COVID-19 pandemic. Avantor added employees and extra shifts in order to increase capacity for producing synthetic lipids that are formed into nanoparticles, which carry mRNA into human cells.

In June 2021, Avantor acquired China-based RIM Bio, a manufacturer of single-use bioprocess bags and assemblies for biopharmaceutical manufacturing applications.

Through the acquisition, Avantor gained access to RIM's Changzhou, China facility, marking Avantor's first single-use production plant in the Africa, Middle East, Asia (AMEA) region. The deal is part of a larger expansion of the company's single-use manufacturing footprint with plans to increase its presence by 30%.

Risk factors and legal proceedings

The risks Avantor names in Item 1A of its 10-K filed Feb 11, 2026: 38 risks under these headings, as written.16

  • Risks related to our business and our industry
  • Significant interruptions in our operations could harm our business, financial condition and results of operations.
  • We have been impacted by supply chain constraints and inflationary pressures
  • We compete in highly competitive markets. Failure to compete successfully could adversely affect our business, financial condition and results of operations.
  • It may be difficult for us to implement our strategies for improving growth and optimizing costs.
  • Part of our growth strategy is to pursue strategic acquisitions, which will subject us to a variety of risks that could harm our business.
  • The customers we serve have experienced, and will continue to experience, significant industry-related changes that could adversely affect our business.
  • Reductions in customers’ research budgets or government funding may adversely affect our business.
  • Our offerings are highly complex, and, if our products do not satisfy applicable quality criteria, specifications and performance standards, we could experience lost sales, delayed or reduced market acceptance of our products, increased costs and damage to our reputation.
  • The loss of a significant number of customers or a significant reduction in customer orders could reduce our net sales and harm our operating results.
  • We are subject to risks associated with doing business globally, which may harm our business.
  • Changes in exchange rates can adversely affect our financial condition, results of operations and cash flows.
The other 27 risks
  • Our business depends on our ability to use and access information systems, and any failure to successfully maintain these systems or implement new systems to handle our changing needs could materially harm our operations.
  • Our actual or perceived failure to adequately protect personal data could adversely affect our business.
  • Our inability to protect our intellectual property could adversely affect our business. In addition, third parties may claim that we infringe their intellectual property, and we could suffer significant litigation or licensing expenses as a result.
  • Our trademarks are valuable assets and if we are unable to protect them from infringement, our business prospects may be harmed.
  • We are subject to product liability and other claims in the ordinary course of business.
  • We must develop new products, adapt to rapid and significant technological change and respond to introductions of new products by competitors to remain competitive.
  • We depend upon the availability of raw materials.
  • We depend upon maintaining our relationships with suppliers.
  • Our use of chemicals and chemical processes is subject to inherent risk.
  • Climate change, and the legal or regulatory response thereto, may have a long-term impact on our business, financial condition and results of operations.
  • We are highly dependent on our senior management and key employees.
  • The indemnification provisions of acquisition agreements by which we have acquired companies may not fully protect us and as a result, we may face unexpected liabilities.
  • We face risks related to health epidemics and pandemics.
  • Changes in tax law relating to multinational corporations could adversely affect our tax position.
  • Certain of our businesses rely on relationships with collaborative partners and other third parties for development, supply and marketing of certain products and potential products, and such collaborative partners or other third parties could fail to perform sufficiently.
  • Risks related to regulation
  • We are required to comply with a wide variety of laws and regulations, and are subject to regulation by various federal, state and foreign agencies, and our failure to comply with existing and future regulatory requirements could adversely affect our results of operations and financial condition.
  • Our reputation, ability to do business and financial statements may be impaired by improper conduct by any of our employees, agents or business partners.
  • We are subject to laws and regulations governing government contracts, and failure to address these laws and regulations or comply with government contracts could harm our business by leading to a reduction in sales to these customers or penalties.
  • We are subject to environmental, health and safety laws and regulations, and costs to comply with such laws and regulations, or any liability or obligation imposed under such laws or regulations, could negatively impact our business, financial condition and results of operations.
  • Changes in corporate governance and public disclosure requirements and expectations could impact compliance costs and the risks of noncompliance.
  • Changes to trade policy, including new or increased tariffs and changing import/export regulations, may adversely affect our business, financial condition and results of operations.
  • Risks related to our indebtedness
  • Our indebtedness could adversely affect our financial condition and prevent us from fulfilling our debt or contractual obligations.
  • Despite our current level of indebtedness, we and our subsidiaries may still be able to incur substantially more debt.
  • Risks related to ownership of our stock
  • Because we have no current plans to pay cash dividends on our common stock, you may not receive any return on investment unless you sell your common stock for a price greater than that which you paid for it.
  • If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results.
  • Our amended and restated certificate of incorporation provides, subject to limited exceptions, that state and federal courts (as appropriate) located within the State of Delaware will be the sole and exclusive forum for certain stockholder litigation matters, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or stockholders.
  • Our business could be impacted as a result of actions by activist shareholders or others.
