Forward-Looking Statements

This Report contains “forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Generally, the words “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” "contemplate," "predict," "outlook," “forecast,” “likely,” “believe,” “target,” “goal,” “objective,” “will,” “could,” “would,” “should,” "potential," "may" and similar expressions or their negative, may, but are not necessary to, identify forward-looking statements. By their nature, forward-looking statements address uncertain matters and include any statements that: are not historical, such as statements about our strategy, financial plans, outlook, objectives, plans, intentions or goals (including those related to our social, environmental and other sustainability goals); or address possible or future results of operations or financial performance, including statements relating to orders, revenues, operating margins and earnings per share growth.

Although we believe that expectations reflected in any of our forward-looking statements are reasonable, actual results could differ materially from those projected or assumed in any of our forward-looking statements. Our future financial condition, results of operations, and any forward-looking statements are subject to change and to inherent risks and uncertainties, many of which are beyond our control. Important factors that could cause our actual results, performance and achievements, or industry results to differ materially from estimates or projections contained in or implied by our forward-looking statements include, among others, the following: the impact of overall industry and general economic conditions, including industrial, governmental, and public and private sector spending, interest rates, availability of funding for customers, inflation and governments’ related monetary policy in response, and the strength of the real estate markets, on economic activity and our operations; geopolitical matters, including nationalism, protectionism and anti-global sentiment, volatility involving the U.S. and other governments, ongoing, escalation or outbreak of international conflicts, and regulatory, trade protection, economic and other risks associated with our global sales and operations; manufacturing and operating cost increases due to macroeconomic conditions, including inflation, energy supply, supply chain shortages, logistics challenges, labor shortages, trade agreements, tariffs, and other trade protection measures, and other factors; demand for our products, disruption, competition or pricing pressures in the markets we serve; cybersecurity incidents, data breaches, or other disruptions of information technology systems on which we or our customers rely, or involving our connected products and services; lack of availability or delays in receiving parts and raw materials from our supply chain, including semiconductors or other key components; operational disruptions at our facilities or that of third parties upon which we rely; safe and compliant treatment and handling of water, wastewater and hazardous materials; failure to successfully execute large projects, including as respects performance guarantees and customers’ budgets, timelines and safety requirements; our ability to retain, compete for and attract leadership, other key talent and labor; defects, security, warranty and liability claims, and recalls related to our products; uncertainty around productivity, simplification, restructuring and realignment actions and related costs and savings; our ability to execute strategic investments for growth, including acquisitions and divestitures; availability, regulation or interference with radio spectrum used by certain of our products; volatility in served markets or impacts on our business and operations due to weather conditions, volatile weather events, or changing climate patterns; risks related to our sustainability efforts and related disclosures; fluctuations in foreign currency exchange rates; difficulty predicting our financial results; risk of future impairments to goodwill and other intangible assets; changes in our effective tax rates or tax expenses; failure to comply with, or changes in, laws or regulations pertaining to our business conduct, operations, products and services, including anti-corruption, artificial intelligence, data privacy and security, trade, competition, the environment, and health and safety; legal, governmental or regulatory claims, investigations or proceedings and associated contingent liabilities; matters related to intellectual property infringement or expiration of rights; and other factors set forth under “Item 1A. Risk Factors” in this Report and in subsequent filings we make with the Securities and Exchange Commission (“SEC”).

Forward-looking and other statements in this Report regarding our environmental and other sustainability efforts, plans and goals are not an indication that these statements are necessarily material to investors, to our business, operating results, financial condition, outlook, or strategy, to our impacts on sustainability matters or other parties, or are required to be disclosed in our filings with the SEC or other regulatory authorities, and are not intended to create legal rights or obligations. In addition, historical, current, and forward-looking social, environmental and sustainability-related statements may be based on: standards for measuring progress that are still developing; internal controls and processes that continue to evolve, and assumptions that are subject to change in the future. All forward-looking statements made herein are based on information currently available to us as of the date of this Report. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.
