PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The information below describes material developments in a proceeding that we previously reported in our annual report on Form 10-K for the year ended December 31, 2024. During the three months ended June 30, 2025, there were no new proceedings required to be disclosed in this item under SEC regulations.

Environmental Enforcement Matters

We are reporting the following proceeding to comply with SEC regulations, which require us to disclose certain information about proceedings arising under federal, state, or local provisions regulating the discharge of materials into the environment or primarily for the purpose of protecting the environment if a governmental authority is a party to such proceeding and we reasonably believe that such proceeding will result in monetary sanctions that exceed a specified threshold. Pursuant to SEC regulations, we use a threshold of $1 million for purposes of determining whether disclosure of any such proceeding is required. We believe any such proceedings less than this threshold are not material to our business and financial condition.

Texas Attorney General (Texas AG) (Port Arthur Refinery). In our annual report on Form 10-K for the year ended December 31, 2024, we reported that the Texas AG had filed suit against our Port Arthur Refinery on July 19, 2019, in the 419th Judicial District Court of Travis County, Texas, Cause No. D-1-GN-19-004121, for alleged violations of the Clean Air Act seeking injunctive relief and penalties. This matter has been resolved with the Texas AG.
