Item 1A. Risk Factors

The risks set forth in “Risk Factors” included in our 2022 Form 10-K could have a material adverse effect on our financial position, results of operations, or liquidity in a particular year or quarter, and could cause those results to differ materially from those expressed or implied in our forward-looking statements. Those risks are updated to include the following risks.

INCIDENT RISKS

As defined and as further described in Note 10 in the Notes to Consolidated Financial Statements, there was an Incident that occurred in the first quarter that consisted of a February 3, 2023 train derailment in East Palestine, Ohio that included 11 non-Company-owned tank cars containing hazardous materials, fires associated with the derailment that threatened certain of the tank cars, and a controlled vent and burn procedure conducted on February 6, 2023 on five of the derailed tank cars, all of which contained vinyl chloride. As a result of the Incident, we have become subject to numerous legal, regulatory, legislative and other proceedings related thereto, including but not limited to, the NTSB Investigation, the FRA Incident Investigation, the FRA Safety Assessment, the DOJ Complaint, the Ohio Complaint, the Incident Lawsuits, the Shareholder Lawsuits, and the Incident Inquiries and Investigations, in addition to other proceedings, actions, or potential changes in response to the Incident, including but not limited to those related to, among other items, train size, train length, train composition, or crew size (collectively, the “Incident Proceedings”). Set forth below are additional risks pertaining to an investment in the Company that are related to the Incident and the Incident Proceedings.

New or additional governmental regulation and/or operational changes resulting from or related to the Incident or the Incident Proceedings may negatively impact us, our customers, the rail industry, or the markets we serve. The legislative, regulatory, operational or other actions taken, protocols adopted (including by us), or changes resulting from the Incident or any of the Incident Proceedings may, either individually or in the aggregate, negatively impact us, our customers, the rail industry, or the markets we serve. Our inability to comply with the requirements of any new or additional laws, regulations or operating protocols resulting from or related to the Incident or the Incident Proceedings may have a material adverse effect on our financial position, results of operations, liquidity, or operations.

The costs, liabilities, fines, penalties, and/or financial impact resulting from or related to the Incident or the Incident Proceedings may be significant, exceed expected or accrued amounts, or negatively affect our financial results. We have incurred and will continue to remain subject to incurring significant costs, liabilities, fines, and penalties related to the Incident and the Incident Proceedings, including amounts that may have a material adverse effect on our financial position, results of operations, or liquidity.

In addition, while we have provided estimates of probable and reasonably estimable liabilities with respect to the Incident and the Incident Proceedings, we cannot predict the final outcome or estimate the reasonably possible range of loss with certainty and such estimates may change over time due to a variety of factors, including but not limited to those set forth in Note 10 hereto or other unfavorable or unexpected developments or outcomes which could result in our current estimates being insufficient. These estimated amounts also do not include any estimate of loss for specific items for which we believe a loss is either not probable or not reasonably estimable for the reasons set forth in Note 10 hereto. As a result, our currently accrued amounts of estimated liabilities may be insufficient, and any additional, new or updated accruals may potentially have a material adverse effect on our results of operations or financial position.
