Securities Trading Plans of Directors and Executive Officers

During the three months ended December 31, 2025, the following officer (as defined in Rule 16a-1(f) under the Exchange Act) adopted a written plan intended to satisfy the affirmative defense conditions of Rule 10b5-1(c).

Other than as disclosed below, no directors or executive officers adopted, modified orterminated any contract, instruction or written plan for the purchase or sale of Company securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) or any “non-Rule 10b5-1 trading arrangement.”

(1)The Rule 10b5-1 trading arrangement allows for the sale of shares subject to future vesting of equity awards, including performance stock unit awards, net of shares withheld for taxes. The exact number of shares sold depends on settlement outcomes and tax withholdings, and therefore is not yet determinable.

Disclosure Pursuant to Section 13(r) of the Securities Exchange Act of 1934

Section 13(r) of the Securities Exchange Act of 1934, as amended, requires an issuer to disclose certain information in its periodic reports if it or any of its affiliates knowingly engaged in certain activities, transactions or dealings with individuals or entities subject to specific U.S. economic sanctions during the reporting period.

In the first quarter of 2025, the Company received a report regarding certain payments to local government officials in Mexico that commenced prior to the Company’s acquisition of its Mexican affiliate in connection with the April 1, 2024 CSI Acquisition that may present potential compliance issues under U.S. law. In response, the Company retained outside counsel to conduct an internal investigation of the reported payments, including whether any payments made may be indirectly benefiting individuals associated with certain criminal cartel organizations, some of which may be designated as foreign terrorist organizations (“FTOs”) and Specially Designated Global Terrorists (“SDGTs”) per Executive Order 14157 of January 20, 2025. The investigation is substantially complete and has determined that certain payments likely were made to persons associated with an organization designated as SDGT. The payments appear to have been made in order to protect employees of the Mexican business from threats of harm or harassment, and to ensure access to work sites. At this time, the Company believes the aggregate amount of these payments was not material. The Company sold its operations and legal entities in Mexico on September 30, 2025.
