The forward-looking statements included in this Current Report are based on our current expectations, projections, estimates and assumptions. These statements are only predictions, not guarantees. Such forward-looking statements are subject to numerous risks and uncertainties that are difficult to predict.

These risks and uncertainties may cause actual results to differ materially from what is forecast in such forward-looking statements, and include, without limitation, the following: global supply chain disruptions and the current inflationary environment could adversely affect the efficiency of our manufacturing and increase the cost of providing our products to customers; a portion of our bookings may not lead to completed sales, and our ability to convert bookings into revenues at acceptable profit margins; changes in global economic conditions and the potential for unexpected cancellations or delays of customer orders in our reported backlog; our dependence on our customers’ ability to make required capital investment and maintenance expenditures; if we are not able to successfully execute and realize the expected financial benefits from any restructuring and realignment initiatives, our business could be adversely affected; the substantial dependence of our sales on the success of the energy, chemical, power generation and general industries; the adverse impact of volatile raw materials prices on our products and operating margins; economic, political and other risks associated with our international operations, including military actions, trade embargoes, epidemics or pandemics and changes to tariffs or trade agreements that could affect customer markets, particularly North African, Latin American, Asian and Middle Eastern markets and global oil and gas producers, and non-compliance with U.S. export/re-export control, foreign corrupt practice laws, economic sanctions and import laws and regulations; the impact of public health emergencies, such as outbreaks of epidemics, pandemics, and contagious diseases, on our business and operations; increased aging and slower collection of receivables, particularly in Latin America and other emerging markets; potential adverse effects resulting from the implementation of new tariffs and related retaliatory actions and changes to or uncertainties related to tariffs and trade agreements; our exposure to fluctuations in foreign currency exchange rates, including in hyperinflationary countries such as Argentina; potential adverse consequences resulting from litigation to which we are a party, such as litigation involving asbestos-containing material claims; expectations regarding acquisitions and the integration of acquired businesses; the potential adverse impact of an impairment in the carrying value of goodwill or other intangible assets; our dependence upon third-party suppliers whose failure to perform timely could adversely affect our business operations; the highly competitive nature of the markets in which we operate; if we are not able to maintain our competitive position by successfully developing and introducing new products and integrate new technologies, including artificial intelligence and machine learning; environmental compliance costs and liabilities; potential work stoppages and other labor matters; access to public and private sources of debt financing; our inability to protect our intellectual property in the United States, as well as in foreign countries; obligations under our defined benefit pension plans; our internal control over financial reporting may not prevent or detect misstatements because of its inherent limitations, including the possibility of human error, the circumvention or overriding of controls, or fraud; the recording of increased deferred tax asset valuation allowances in the future or the impact of tax law changes on such deferred tax assets could affect our operating results; our information technology infrastructure could be subject to service interruptions, data corruption, cyber-based attacks or network security breaches, which could disrupt our business operations and result in the loss of critical and confidential information; ineffective internal controls could impact the accuracy and timely reporting of our business and financial results; and other factors described from time to time in our filings with the Securities and Exchange Commission.
