We are currently, and may in the future become, subject to litigation and other claims. These legal proceedings are typically claims that relate to our products or services or to the conduct of our businesses and include, without limitation, claims relating to commercial, regulatory or contractual disputes with suppliers, authorities, customers or parties to acquisitions and divestitures; intellectual property matters; environmental, asbestos, safety and health matters; product quality and liability matters; matters arising from the use or installation of our products; consumer protection matters; matters and employment and labor matters. The outcome of such legal proceedings cannot be predicted with certainty, and some may be disposed of unfavorably to us. In addition to insurance costs rising and insurers decreasing coverage, insurance coverage is not available for some of our claims and may be disputed by carriers in others. While we currently maintain what we believe to be suitable product liability insurance, we may not be able to maintain this insurance on our preferred terms or at an acceptable cost. Further, this insurance may not provide adequate protection against potential or previously existing liabilities. In addition, we self-insure a portion of product liability claims and must satisfy deductibles on other insured claims. Additionally, some Some of our business involves the sale of our products to customers that are constructing large and complex systems, facilities or other capital projects, and while we generally try to limit our exposure to liquidated damages, consequential damages and other potential damages in the contracts for these projects, we could be exposed to significant monetary damages and other liabilities in connection with the sale of our products for these projects for a variety of reasons. In addition, some of our businesses, customers, and dealers are subject to various laws and regulations regarding consumer protection and advertising and sales practices, and we have been named, and may be named in the future, as a defendant in litigation, including class action complaints, arising from alleged violation of these laws and regulations. In addition, our indemnification obligations relating to the purchase or sale of businesses could result in litigation or claims of unknown amounts. Successful claims or litigation against us for significant amounts could have a material adverse effect on our reputation, business, financial condition, results of operations and cash flows.

•During 2024, 2025, we experienced inflationary cost increases for certain raw materials as well as logistics and transportation costs. The ongoing volatile market for commodities has the potential to continue to drive price increases in our supply chain. In addition, the current U.S. administration has recently implemented tariffs and has announced the with an ongoing possibility of implementing additional, or increasing current, tariffs; tariffs. We expect these actions and any additional reactionary tariff adjustments by other countries may also to continue to impact our business and contribute to inflationary cost increases. As a result, we have taken actions to mitigate the impact of tariffs such as pricing increases, inventory pre-buys and supply chain optimization actions, which may continue going forward, and implemented transformation forward. In addition, our Transformation Program initiatives that we expect are intended to improve productivity and offset cost increases. We anticipate that supply chain pressures and inflationary cost increases due to potential tariffs resulting from these tariffs, as well as any related impacts on macroeconomic conditions and pressure on global manufacturing to our business, will likely continue into 2025. 2026. In addition, on February 20, 2026, the U.S. Supreme Court struck down certain tariffs imposed under the International Emergency Powers Act. It is unclear at this time what impact this decision will have on our future financial results, including whether we will be able to obtain refunds of amounts previously collected for such tariffs or the level of replacement tariffs the current U.S. Administration imposes through other means.

Inventories are stated at the lower of cost or net realizable value with substantially all inventories recorded using the first-in, first-out (“FIFO”) cost method. In 2025 and 2024, we recorded inventory impairment of $17.1 million and $11.3 million, respectively, as a result of restructuring and transformation activities. The impairment charges were recorded in Cost of goods sold in our Consolidated Statements of Operations and Comprehensive Income. No material inventory impairment charges were recorded in 2023.

We are subject to various product liability lawsuits and personal injury claims. A substantial number of these lawsuits and claims are insured and accrued for by Penwald, our captive insurance subsidiary. Penwald records a liability for these claims based on actuarial projections of ultimate losses. For all other claims, accruals covering the claims are recorded, on an undiscounted basis, when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on existing information. The accruals are adjusted periodically as additional information becomes available. We have not experienced significant unfavorable trends in either the severity or frequency of product liability lawsuits or personal injury claims.
