Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES We are subject to a number of lawsuits and claims both actual and potential in nature including those involving intellectual property and commercial disputes. For example, we are involved in legal proceedings in certain jurisdictions related to alleged infringement of intellectual property rights, alleged customer breach of confidentiality obligations, alleged customer misuse of proprietary information and alleged violations of competition and antitrust laws. We are actively litigating our interests in these matters and management believes the resolution of these claims and lawsuits will not have a material adverse effect on our financial position, results of operations or cash flows, claims and legal proceedings are subject to inherent uncertainties, and unfavorable outcomes could occur that could include amounts in excess of any accruals which management has established. Were such unfavorable final outcomes to occur, it is possible that they could have a material adverse effect on our financial position, results of operations and cash flows. Legal Proceedings On March 25, 2025, AptarGroup, Inc. and its subsidiary, Aptar France SAS, filed a lawsuit in the United States District Court for the Southern District of New York against ARS Pharmaceuticals, Inc. and ARS Pharmaceuticals Operations, Inc. (together, “ARS”). The complaint alleges that ARS misappropriated Aptar’s trade secrets and breached multiple contractual confidentiality obligations. Aptar seeks injunctive relief and damages. On June 12, 2025, ARS filed a motion to dismiss the complaint, which, on March 30, 2026, the court denied in substantial part and granted in part, specifically in regard to Aptar's state law trade secret misappropriation claim. On April 29, 2026, Aptar moved for leave to amend its complaint to reassert that claim, which the Court granted on June 17, 2026. ARS filed its answer to the amended complaint on July 6, 2026; it did not file any counterclaims against Aptar. This matter is pending and it is currently in the discovery stage. Relatedly, on September 29, 2025, ARS filed a lawsuit in the United States District Court for the Southern District of California against Aptar. The complaint alleges that Aptar violated Sections 1 and 2 of the Sherman Act and Section 3 of the Clayton Act by refusing to sell certain components. ARS seeks injunctive relief and damages. On December 16, 2025, Aptar filed a motion to dismiss the ARS complaint, or to transfer the complaint to the Southern District of New York. ARS opposed the motion on January 27, 2026, and Aptar filed its reply on February 27, 2026. On July 17, 2026, the Court transferred the matter to the Southern District of New York; it did not address the motion to dismiss. At this stage, this matter is too preliminary to form a judgment as to whether an adverse outcome is probable, and we are unable to estimate the possible loss or range of loss, if any. In May 2025, Nemera La Verpillière SAS ("Nemera") filed parallel patent infringement actions in Mannheim Regional Court, Germany (the "Mannheim Court") and Paris Judicial Court, France against Aptar and certain subsidiaries alleging that Aptar's ophthalmic product infringes a Nemera patent, seeking an injunction and damages. Aptar is contesting the claims. Aptar filed oppositions before the European Patent Office ("EPO") challenging the validity of the European Patent (EP) asserted by Nemera. On October 2, 2025, an EPO hearing invalidated Nemera’s main patent claim while allowing an amended claim to continue. Following further EPO proceedings in February 2026, certain asserted claims were dismissed and an amended claim was allowed; both parties filed appeals of the decision, which are pending. The Mannheim Court held a hearing on the patent infringement action on June 23, 2026 and a decision is expected on August 11, 2026. The trial in the French proceeding is scheduled for January 2027. Aptar will continue to monitor developments related to this matter and evaluate the potential impact, if any, on its Condensed Consolidated Financial Statements. Tariff-related Matters On February 20, 2026, the United States Supreme Court ruled that the International Emergency Economic Powers Act (“IEEPA”) does not authorize the imposition of tariffs. thereby invalidating tariffs previously imposed by the US administration under that statute. Subsequent to the decision, a new tariff surcharge of at least 10% was imposed on most imports under Section 122 of the Trade Act of 1974, effective on February 24, 2026, for a period of up to 150 days. Following the ruling, the U.S. Court of International Trade directed U.S. Customs and Border Protection to finalize or revise certain import transactions without applying IEEPA‑based tariffs and is overseeing the development of a refund process. Aptar has historically paid IEEPA-based duties and is evaluating the applicability of these decisions to its import entries, including procedural requirements under U.S. customs law. In accordance with ASC 450‑30, Contingencies—Gain Contingencies, Aptar will account for any potential recovery of previously paid IEEPA tariffs as a gain contingency. As of June 30, 2026, Aptar has received certain tariff refunds and continues to evaluate additional potential recoveries; however, such amounts were not material to our Condensed Consolidated Financial Statements. Other Contingencies Under our Certificate of Incorporation, we have agreed to indemnify our officers and directors for certain events or occurrences while the officer or director is, or was, serving at our request in such capacity. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we have a directors and officers liability insurance policy that covers a portion of our exposure. As a result of our insurance policy coverage, we believe the estimated fair value of these indemnification agreements is minimal. We have no liabilities recorded for these agreements as of June 30, 2026 and December 31, 2025. We are periodically subject to loss contingencies resulting from customs duties assessments. We accrue for anticipated costs when an assessment has indicated that a loss is probable and can be reasonably estimated. We have received claims worth approximately $10.0 million to $11.0 million in principal, and $21.0 million to $22.0 million for interest and penalties. We are currently defending our position with respect to these claims in the respective administrative procedures. Due to uncertainty in the probability of settlement and the timing of our appeal, no liability is recorded as of June 30, 2026. We will continue to evaluate these liabilities periodically based on available information, including the progress of remedial investigations, the status of discussions with regulatory authorities regarding the methods and extent of remediation and the apportionment of costs and penalties among potentially responsible parties.
