Port Arthur Refinery Fire

On March 23, 2026, our Port Arthur Refinery experienced a fire in one of the refinery’s distillate hydrotreater units that prompted a full shut-down of the refinery. As of the date of this quarterly report on Form 10-Q, the Port Arthur Refinery has resumed operations at reduced capacity and efforts remain ongoing to determine the ultimate cause of the incident, assess the full extent of the damages, and implement a plan for making any repairs or replacements. We currently expect that the incident will result in additional capital expenditures in 2026, which should be covered by insurance, subject to our self-insured retention. However, the ultimate timing and amount of any such capital expenditures and insurance proceeds are currently uncertain and are not reasonably estimable at this time. Such capital expenditures may also occur in a different period than when any insurance proceeds may be received. Uncertainties remain with respect to the ultimate outcomes from this incident and the resulting impact on our financial position, results of operations, and cash flows.

We have received a number of lawsuits, including a proposed class action lawsuit, alleging personal injury, property damage, and nuisance in the adjacent community. Several of these actions seek unspecified damages in excess of $1 million. While we intend to vigorously defend against such pending actions, the ultimate outcomes and impacts thereof are currently uncertain and any potential losses or damages cannot be reasonably estimated at this time. We continue to work cooperatively with various regulatory authorities reviewing the incident and discussions are ongoing. As of the date of this quarterly report on Form 10-Q, no formal regulatory actions or proceedings have been commenced. Regulatory actions or proceedings, if any, that may arise in the future, are currently uncertain and we are unable to make any reasonable estimates with respect thereto at this time.

Trade and Other Policy Matters

The U.S. federal government under the current administration implemented new or revised tariffs that negatively impacted our business, particularly our Renewable Diesel segment, during 2025 and into 2026, including those implemented pursuant to the International Emergency Economic Powers Act (IEEPA). On February 20, 2026, the U.S. Supreme Court ruled that tariffs imposed under IEEPA were invalid. On April 20, 2026, the U.S. Customs and Border Protection (CBP) launched a system that was developed to process IEEPA tariff refund claims. Based on the eligibility parameters established by the CBP for the initial phase of the refund process, DGD prepared and filed a refund claim in the amount of $51 million, which has been accepted by the CBP. In accordance with the accounting for gain contingencies, we recorded a receivable for this amount in April 2026. We will continue to monitor developments related to trade and tariff-related matters and evaluate their potential effects on our business, financial position, results of operations, and cash flows.
