AdvanSix Inc.

As previously reported, the Virginia Department of Environmental Quality ("VA DEQ") initiated discussions with the Company regarding certain alleged violations associated with air emissions and water discharges at the Company’s Hopewell facility. The Company entered into an Order by Consent with the VA DEQ in September 2025 in connection with the alleged water discharge violations of the State Water Control Law at the Company’s facility in Hopewell, Virginia, which provided for a civil charge of $55,841. The facility is continuing to assess and discuss the allegations associated with air emissions with the VA DEQ. Although the outcome of the matter cannot be predicted with certainty, we do not believe that it will have a material adverse effect on our consolidated financial position, results of operations or operating cash flows.

From time to time, we are involved in litigation relating to claims arising outside of the ordinary course of our business operations. We are not a party to, and, to our knowledge, there are no pending claims or actions against us, the ultimate disposition of which could be expected to have a material adverse effect on our consolidated financial position, results of operations or operating cash flows.
