The risk factors disclosed in Part I, Item 1A to our Annual Report on Form 10-K for the year ended December 31, 2024, in addition to the other information set forth in this report, including the updated risk factors below, could adversely affect the Corporation’s operating performance and financial condition.

Current report

The imposition of tariffs by the United States has negatively affected, and could continue to negatively affect, our operations, financial performance and liquidity.

Current report

The United States currently imposes tariffs on primary steel imports and aluminum imports into the United States and has expanded tariffs to other imported products. Our geographic production footprint and our cost base is exposed to these tariffs and could be exposed to additional tariffs, higher tariffs or similar actions in the future, which exposes us to deferral of customer orders and pass-through risk to our customers. The tariffs have and could continue to depress overall market conditions as end-market demand in the United States may falter. Volatility in tariff actions has caused deferred demand as markets await more certainty in trade policy. This volatility has and may continue to negatively impact our order backlog. Depending on market demand and capacity utilization of competitors, our products could become less cost competitive over time, exposing us to potential loss of market share. Our financial condition, results of operations and liquidity may be affected by these tariffs, or similar actions. Moreover, these tariffs, or other changes in U.S. trade policy, have resulted in, and may continue to trigger, retaliatory actions by affected countries which could adversely impact demand for our products, as well as impact our costs, customers, suppliers, and/or the U.S. economy or certain sectors thereof and, thus, may adversely impact our business, operations and financial performance.

Current report

We may from time to time undertake internal corporate reorganizations that may adversely impact our business and results of operations.

Current report

From time to time, we have undertaken, and may undertake again, internal corporate reorganizations in an effort to simplify our organizational structure, streamline our operations or to address other operational factors. Such internal reorganization involves and may involve, among other things, the combination or dissolution of certain of our existing subsidiaries, including legal insolvency proceedings, and the creation of new subsidiaries. These transactions could be disruptive to our business, result in significant expense, require regulatory approvals, and fail to result in the intended or expected benefits, any of which could adversely impact our business and results of operations.
