Current report
Both the costs of raw materials used in our manufactured products (copper, brass, zinc, and aluminum) and energy costs (electricity, natural gas and fuel) have been volatile during the last several years, which has resulted in changes in production and distribution costs. Fluctuations in commodities prices are caused by varied and complex factors beyond our control, including global supply and demand impacted by industry production and inventory levels; global economic and political conditions; national and international regulatory, trade and/or tax policies, including tariffs and other controls or restrictions on imports and exports; current inflation rates and expectations regarding future inflation rates; and the strength of the U.S. dollar compared to foreign currencies. For example, tariffs may impact the total cost of our products and the components and raw materials that go into manufacturing them and could adversely impact the gross margin the Company earns on its products. Fuel and utility costs also have been, and will continue to be, affected by factors outside our control, such as supply and demand for fuel and utility services in both local and regional markets, including increased demand resulting from data center development.
Current report
Enhanced U.S. tariffs, import/export restrictions or other trade barriers may have a negative effect on global economic conditions, financial markets and our business.
Current report
There is currently significant uncertainty about the future relationship between the U.S. and various other countries with respect to trade policies, treaties, tariffs and taxes. Current or future tariffs imposed by the U.S. may negatively impact our customers’ businesses, thereby causing an indirect negative impact on our sales. For example, during 2025, the U.S. presidential administration threatened or imposed tariffs on imports from various countries, including China, Mexico, and Canada. In response, some of these countries threatened or announced tariffs on imports from the U.S. Further, on February 20, 2026, the United States Supreme Court issued a ruling striking down certain tariffs previously imposed under the International Emergency Economic Powers Act (IEEPA). Following the Supreme Court's decision, the U.S. presidential administration announced its intention to invoke other laws to collect tariffs and announced new tariffs on imports from all countries, in addition to any existing non-IEEPA tariffs. There remains substantial uncertainty regarding the duration of existing and newly announced tariffs, potential changes or pauses to such tariffs, tariff levels, and whether further additional tariffs or other retaliatory actions may be imposed, modified, or suspended, and the impacts of such actions on our business. The extent to which these threats will be enacted and the duration for which enacted tariffs will be in place remain uncertain and could lead to economic decline, which could negatively impact demand for our products and adversely affect our results of operations.
Reworded paragraphs (2)
Previous wording
Both the costs of raw materials used in our manufactured products (copper, brass, zinc, and aluminum) and energy costs (electricity, natural gas and fuel) have been volatile during the last several years, which has resulted in changes in production and distribution costs. For example, recent and pending climate change regulation and initiatives on the state, regional, federal, and international levels that have focused on reducing greenhouse gas (GHG) emissions from the energy and utility sectors may affect energy availability and costs in the near future. Tariffs impact the total cost of our products and the components and raw materials that go into manufacturing them. The new, substantial tariff increases on imports in the United States from Canada and Mexico (in addition to China) announced on February 1, 2025, should they be implemented and sustained for an extended period of time, could adversely impact the gross margin the Company earns on its products. While we typically attempt to pass costs through to our customers or to modify or adapt our activities to mitigate the impact of increases, we may not be able to do so successfully. The Company is prepared to proactively work with its supply chain to mitigate the cost impact and pass increases in costs to its customers, to the extent possible, when they occur, but failure to fully pass increases to our customers or to modify or adapt our activities to mitigate the impact could have a material adverse impact on our operating margins. Additionally, if we are for any reason unable to obtain raw materials or energy, our ability to manufacture our products would be impacted, which could have a material adverse impact on our operating margins.

Previous wording
We conduct our business through subsidiaries in several different countries and export our products to many countries. Fluctuations in currency exchange rates could have a significant impact on the competitiveness of our products as well as the reported results of our operations, which are presented in U.S. dollars. A portion of our products are manufactured in or acquired from suppliers located in lower cost regions. Cross border transactions, both with external parties and intercompany relationships, result in increased exposure to foreign exchange fluctuations. The strengthening of the U.S. dollar could expose our U.S. based businesses to competitive threats from lower cost producers in other countries such as China. Lastly, our sales are translated into U.S. dollars for reporting purposes. The strengthening of the U.S. dollar could result in unfavorable translation effects when the results of foreign operations are translated into U.S. dollars. Accordingly, significant changes in exchange rates, particularly the British pound sterling, Mexican peso, Canadian dollar, and the South Korean won, could have an adverse impact on our results of operations or financial position.
