We have conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of March 31, 2024. Based on this evaluation of our disclosure controls and procedures, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of March 31, 2024, such that the information required to be disclosed in our Securities and Exchange Commission reports is recorded, processed, summarized and reported within the time periods specified by the rules and forms of the Exchange Act and is accumulated and communicated to management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures.

Changes in Internal Control Over Financial Reporting

There were no changes in the Company’s internal controls over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the quarter ended March 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II OTHER INFORMATION

SEC regulations require the Company to disclose certain information about administrative or judicial proceedings involving certain environmental matters to which a governmental authority is a party if the Company reasonably believes that such proceedings may result in monetary sanctions above a specified threshold. Pursuant to SEC regulations, the Company has adopted a threshold of $1.0 million for purposes of determining whether disclosure of any such proceedings is required. The Company believes that this threshold is reasonably designed to result in disclosure of any such proceedings that are material to its business or financial condition.

Developments in the Company’s legal proceedings are described below:

Maywood, New Jersey Site

The Company’s property in Maywood, New Jersey, property formerly owned by the Company adjacent to its current site and other nearby properties (collectively, the Maywood site) were listed on the National Priorities List in September 1993 pursuant to the provisions of CERCLA because of alleged chemical and radiological contamination. On September 24, 2014, the USEPA issued its Record of Decision (ROD) for chemically-contaminated soil at the Maywood site. The ROD was amended pursuant to an Explanation of Significant Differences in January 2021. On February 29, 2024, the U.S. District Court for the District of New Jersey entered a consent decree among the Company, the United States, the New Jersey Department of Environmental Protection (NJDEP) and the New Jersey Spill Compensation Fund Administrator that requires the Company to take certain actions and to pay certain past costs of the United States and NJDEP.

Millsdale Site

On March 26, 2024, the Company received a Notice and Finding of Violation from the USEPA alleging violations of air regulations at the Company’s Millsdale facility. The notice alleges violations related to operating parameters and air emission requirements. The notice does not state whether the USEPA intends to pursue financial penalties or operational remedies. The alleged violations may result in a range of possible penalties; however, at this stage of the matter, the Company is unable to predict the ultimate outcome or what impact, if any, the outcome might have on the Company’s results of operations or cash flows.

There have been no other material changes to the legal proceedings disclosed in the Company’s 2023 Annual Report on Form 10-K.
