VALERO ENERGY CORP/TX

The information below describes a new proceeding required to be disclosed in this item under SEC regulations for the three months ended June 30, 2026.

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.

Bay Area Air Quality Management District (BAAQMD) (Benicia Refinery). Between 2019 and 2023, our Benicia Refinery received various Violation Notices (VNs) from the BAAQMD for excess emissions, among other violations. While no single VN exceeded the materiality threshold, such VNs were aggregated and resolved with the BAAQMD during the second quarter of 2026.
