APTARGROUP, INC.

Our operations and financial results are subject to various risks and uncertainties, including the factors discussed in Part I, Item 1A, Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2024, which could adversely affect our business, financial conditions and future results. Other than the risk factors set forth below, there have been no material changes from the risk factors discussed in our Annual Report.

We are exposed to risks from lawsuits and claims, including product liability claims, as well as investigations, audits and other proceedings, which may result in substantial costs and expenses or interruption of our normal business operations. We are subject to a number of lawsuits and claims that arise in the ordinary course of our business, which include intellectual property infringement, product liability, commercial, employment, tort, business interruption and other litigation. For example, in May 2025, Nemera filed patent infringement actions against us in France and Germany relating to certain of our ophthalmic products. In October 2025, an EPO hearing invalidated Nemera’s main patent claim while allowing an amended claim to continue. In addition, in September 2025, ARS Pharmaceuticals Operations, Inc. filed an antitrust lawsuit against us in the United States District Court for the Southern District of California, alleging violations of U.S. competition laws related to supply of certain components and are seeking injunctive relief and damages. Refer to Note 12 – Commitments and Contingencies of the Notes to the Condensed Consolidated Financial Statements for additional information regarding these actions.

We are also subject to indemnification claims under various contracts. Further, the failure of our products to operate as intended may result in a product liability claim against us. We believe we maintain adequate levels of product liability insurance coverage and robust quality control systems at our facilities. However, a product liability claim in excess of our insurance coverage or not covered by existing insurance may materially adversely affect our business, results of operations or cash flows.

In addition, we are subject to investigations, audits and other proceedings initiated by federal, state, international, national, provincial and local authorities, including regulatory agencies such as the FDA as a result of the products manufactured by our Aptar Pharma segment.

Current and future litigation, claims, investigations, audits and other proceedings or indemnification claims that we face may result in substantial costs and expenses and significantly divert the attention of our management regardless of the outcome. In addition, these matters could lead to increased operating costs or interruptions of our normal business operations or could result in restrictions on our ability to manufacture or sell certain products or operate specific product lines. Litigation, proceedings and indemnification claims involve uncertainties and the eventual outcome of any such matter could adversely affect our business, results of operations or cash flows.

Challenges to, or the loss of, our intellectual property rights could have an adverse impact on our ability to compete effectively. Our ability to compete effectively depends, in part, on our ability to protect and maintain the proprietary nature of our owned and licensed intellectual property. We own a large number of patents on our products, aspects of our products, methods of use and/or methods of manufacturing, and we own, or have licenses to use, all of the material trademark and trade name rights used in connection with the packaging, marketing and distribution of our major products. We also rely on trade secrets, know-how and other unpatented proprietary technology. We attempt to protect and restrict access to our intellectual property and proprietary information by relying on the patent, trademark, copyright and trade secret laws of the U.S. and other countries, as well as non-disclosure agreements. However, it may be possible for a third party to obtain our information without our authorization, independently develop similar technologies, or breach a non-disclosure agreement entered into with us. For example, in March 2025, we filed a lawsuit against ARS Pharmaceuticals, Inc. and ARS Pharmaceuticals Operations, Inc. alleging that our confidential information and trade secrets were improperly disclosed and used. Refer to Note 12 – Commitments and Contingencies of the Notes to the Condensed Consolidated Financial Statements for additional information.

Furthermore, many of the countries in which we operate do not have intellectual property laws that protect proprietary rights as fully as do laws in the U.S. The use of our intellectual property by someone else without our authorization could reduce or eliminate certain of our competitive advantages, cause us to lose sales or otherwise harm our business. The costs associated with protecting our intellectual property rights could also adversely impact our business.

We are also from time to time subject to claims from third parties suggesting that we may be infringing on their intellectual property rights. For example, in May 2025, Nemera filed patent infringement actions against us in France and Germany relating to certain of our ophthalmic products. In October 2025, an EPO hearing invalidated Nemera’s main patent claim while allowing an amended claim to continue. Refer to Note 12 – Commitments and Contingencies of the Notes to the Condensed Consolidated Financial Statements for additional information.

Defending against such claims, or initiating legal action to protect our own rights, may involve significant legal expenses, operational disruptions, and diversion of management attention. Intellectual property litigation, which could result in substantial cost to us and divert the attention of management, may be necessary to protect our trade secrets or proprietary technology or for us to defend against claimed infringement of the rights of others and to determine the scope and validity of others’ proprietary rights. We may not prevail in any such litigation, and if we are unsuccessful, we may not be able to obtain any necessary licenses on reasonable terms or at all or such litigation may result in restrictions on our ability to manufacture or sell certain products or operate product lines. Failure to protect our patents, trademarks and other intellectual property rights, or failure to successfully defend against intellectual property litigation, may have a material adverse effect on our business, consolidated financial condition or results of operations.
