Inventory and Backlog
The Company is a short cycle business and backlog is not generally considered a significant factor as relatively short delivery periods and rapid inventory turnover are characteristic of most of the Company’s products. Even still, the Company regularly and systematically adjusts production schedules and quantities based on the flow of incoming orders. While backlog was elevated in recent years due to global supply chain constraints, which extended lead times, shifted customer order patterns and resulted in increased inventory to support production, customer destocking efforts in 2023 have resulted in orders stabilizing with backlog and lead times returning to more normalized levels. The Company remains focused on delivering products and services to customers and continues to actively manage inventory levels. Further, the Company has not historically experienced significant order cancellations and does not expect significant order cancellations in the future.
Government Regulations
Our compliance with federal, state and local laws and regulations, including those related to environmental, international trade, labor and employment, human rights, tax, anti-bribery and competition matters, did not have a material effect upon our capital expenditures, earnings or competitive position during the fiscal year ended December 31, 2023.
Employees
At December 31, 2023, the Company had approximately 8,800 employees. Approximately 4% of its employees are covered by various collective bargaining agreements in the U.S. which will expire at various times between now and June 2028. There are no collective bargaining agreements in the U.S. that will expire within one year. Management believes that the Company has a positive relationship with its employees. The Company historically has been able to renegotiate its collective bargaining agreements satisfactorily, with its last work stoppage occurring in March 1993.
Human Capital Management
The Company recognizes that its success would not be possible without the valuable contributions of its workforce and is committed to creating a work environment where employees can thrive and grow. Our workplaces promote entrepreneurialism and autonomy while providing a strong safety net of benefits, training and personal development. Investments in attracting, retaining and developing great teams enables the Company to accomplish its goals and deliver innovative customer solutions. The Company’s corporate Human Capital strategy is overseen by its Chief Human Resource Officer (“CHRO”). Annually, the CHRO presents a talent review to the Company’s Board of Directors focused on senior leader team development, the human capital strategy action plan and succession planning for senior management to ensure that the Board is informed and to seek alignment on plans about human capital management for business continuity and success.
The Company’s workforce advancement strategy is focused through investment in three pillars: skill-building for the entire workforce, leadership development aligned with the Company’s methodology and fostering a premier culture. The Company’s approach to performance management, talent development, talent management and employee engagement helps drive long-term value by providing employees with opportunities to do and be their best both individually and as teams.
As part of our Organizational Talent Cycle process, we conduct regular in-depth talent reviews of our workforce teams and culture with business leaders, identify “stretch” opportunities to grow team members and connect our decentralized businesses by moving skilled employees from one business unit to another as opportunities and interest arise. Employees and leaders have performance and development conversations throughout the year, talking about business and development goals, reviewing progress, recognizing accomplishments, giving balanced feedback and identifying opportunities for improvement. Open, honest dialog about performance, development and career growth supports our values of Trust, Team and Excellence and The IDEX Difference, building trust and helping us fulfill our purpose.
The Company offers agile development solutions to support unique needs and drive long-term value. Employees have access to resources that enhance and build capabilities for success in their current position or future roles, including specific individual development plans and local training and development programs. Each year, the Company invests in a Global Leadership Conference for senior leaders to align on strategic vision and priorities and build core leadership skills. In support of our growth strategy and culture, the Company also sponsors accelerated, on-the-job learning for key leaders in our pipeline through the IDEX Academy’s global leadership development programs. These programs provide opportunities for emerging leaders across geographies and businesses to come together to practice and apply new leadership behaviors, share best practices, solve business challenges and build strong support networks. Our learning curriculum includes instructor-led, self-paced and blended solutions that have been created internally or sourced from external partners. These offerings also help to develop future and potential leaders in the IDEX leadership methodology. Additionally, the Company sponsored over 150 senior leaders

to participate in a coaching skill-building program in 2023 with continued on-the-job performance support and reinforcement designed to accelerate the growth and development of our high-performing talent and further promote our growth culture.
The Company also enables employee development and growth by offering eligible U.S. employees the opportunity to participate in the Tuition Reimbursement program. Through the program, employees can have certain expenses from secondary educational institutions reimbursed up to $5,250 per year.
The Company prioritizes hiring team members who will embrace the team-driven culture and also places considerable emphasis on leveraging the talented employees within the Company’s internal pipeline, filling many leadership positions with Company employees.
Part of the IDEX Difference is building and engaging great teams. Employee engagement is essential to create a diverse, inclusive and equitable culture where all employees thrive and have an equal opportunity to do and be their best. We believe our employees have a high level of engagement as the Company’s employee engagement index remains above the average for manufacturing companies at 74 percent, as measured by the Company’s employee engagement survey. The Company’s investments in people have led to significant increases in favorability for career development for all employees. Additionally, the important capability-building investments of the Global Leadership Conference and coaching programs have positively impacted senior leader perceptions of learning and development, support for skill and career development and increased confidence of being able to achieve career goals at IDEX.
Diversity, Equity & Inclusion
The Company has always recognized diversity as foundational to creativity and resilience; the three pillars of Innovation, Diversity and Excellence form the acronym that is the Company’s name, IDEX. Gender, ethnic, cultural and other human diversity is critical to the Company’s success.
In 2022, the Company launched its Diversity, Equity and Inclusion (“DEI”) strategic roadmap. In 2023, progress against the strategic roadmap included: (1) implementation of mentoring based on employee resource groups (“ERGs”) and talent development networks; (2) delivery of Inclusive Leadership Training; (3) increased participation in IDEX ERGs; (4) continuation of IDEX’s performance-based DEI goals for senior leaders; and (5) expansion of talent development and recruiting efforts.
IDEX has built a reputation as a respected employer with a welcoming culture, where 80% of employees feel a strong sense of belonging, according to our 2023 employee engagement survey.
The Company’s Board of Directors now comprises 30% women and 30% members who identify with racial/ethnic minority groups. Additionally, the representation of women in leadership at the Company remained steady in 2023. From 2022 to 2023, and as of December 31, 2023, the percentage of women globally in senior leadership roles remained constant at 31%. The percentage of women globally in people leadership roles remained at 22%. During the same time period, and as of December 31, 2023, the number of racial/ethnic minority senior leaders in the U.S. increased from 21% to 22%, and the number of racial/ethnic minority people managers in the U.S. increased from 19% to 20%. The foregoing representation numbers do not include employee populations associated with acquisitions completed in 2023.
Further, the Company has conducted pay equity analyses for U.S. employees since 2018 to ensure that employees’ actual pay was substantially similar to their predicted pay. Where appropriate, the Company provided base pay adjustments for employees that were outliers from their predicted pay, further reinforcing the Company’s commitment to diversity and a culture of inclusion, equality and respect.
Employee Pay and Benefits
Attracting and retaining top talent is critical to the success of the Company’s business. The Company offers a highly competitive pay and benefits package for employees in all the markets where it operates. The performance-based pay packages provide many employees with short-term performance incentives. The Company also provides equity-based, long-term incentives to its senior leaders.
The Company’s U.S. employees can participate in a 401(k) retirement plan and an Employee Stock Purchase Plan, which allows an employee to purchase IDEX stock through payroll deductions.

Workplace Health & Safety
The Company is committed to providing a workplace that is safe for all of our employees, contractors, business partners and visitors. The commitment to Environmental, Health, and Safety (“EH&S”) begins at the corporate and executive level. The program is overseen by the EH&S Senior Director and the Chief Sustainability Officer, both of whom are part of the Legal Department. Each of the Company’s businesses employ local EH&S specialists. These individuals and local safety committees, in conjunction with the corporate team, form the basis of the global EH&S program. The Company’s corporate EH&S policies are a key part of the global EH&S program. They apply to all of the Company’s businesses and each business is expected to comply with policies and all EH&S laws and regulations. In addition to the corporate policies, each business develops and implements its own health and safety policies tailored to the local business.
The Company also encourages employees enrolled in the U.S. Healthcare Benefit Plan to participate in the third-party operated Wellness Program which provides access to annual biometric screenings, health evaluations and wellness credits that can be earned for meeting individual wellness goals each year. In addition, a number of the business units organize complementary wellness programs, including walking clubs, health fairs and “lunch and learns” with nutritionists for their employees.
Worker Rights and Protection
The Company believes that a respectful workplace is free from unlawful discrimination and harassment, and this involves more than just compliance with the law. The Company strives to create a work environment that is free of inappropriate and unprofessional behavior and consistent with the Company’s values – a place where everyone is invited to do their best every day and feel free to report any concerns. The Company has policies, procedures and regular training in place to protect its workforce and prevent workplace harassment and discrimination. This includes a global Code of Business Conduct & Ethics policy where employees agree to follow and receive annual training. The Company also maintains a global hotline where employees are encouraged (and can choose to remain anonymous) to report any concerns or issues.

Item 1A. Risk Factors.
For an enterprise as diverse and complex as the Company, a wide range of factors present risks to the Company and could materially affect future developments and performance. In addition to the factors affecting specific business operations identified in connection with the description of the Company’s operations and the financial results of its operations elsewhere in this report, the most material of these factors are included below. Current global economic events and conditions may amplify many of these risks. These risks are not the only risks that may affect the Company. Additional risks that the Company is not aware of or does not believe are material at the time of this filing may also become important factors that adversely affect the Company’s business.
Risks Related to the Company’s Operations
The Company’s Inability to Continue to Develop New Products Could Limit Sales Growth.
The Company’s ability to continue to grow organically is tied in large part to its ability to continue to develop new products. A failure to continue to develop and deliver new, innovative and competitive products to the market could limit sales growth and negatively impact the Company and its financial condition, results of operations and cash flow.
The Company’s Growth Strategy Includes Acquisitions and the Company May Not be Able to Make Acquisitions of Suitable Candidates or Integrate Acquisitions Successfully.
The Company’s historical growth has included, and the Company’s future growth is likely to continue to include, acquisitions. The Company intends to continue to seek acquisition opportunities both to expand into new markets and to enhance its position in existing markets throughout the world. The Company may not be able to successfully identify suitable candidates, negotiate appropriate acquisition terms, obtain financing needed to consummate those acquisitions, complete proposed acquisitions or successfully integrate acquired businesses into its existing operations. In addition, any acquisition, once successfully integrated, may not perform as planned, be accretive to earnings, or otherwise prove beneficial to the Company.
Acquisitions involve numerous risks, including the assumption of undisclosed, uninsured or unindemnified liabilities; difficulties in the assimilation of the operations, technologies, services and products of the acquired companies and the diversion of management’s attention from other business concerns. In addition, prior acquisitions have resulted in, and future acquisitions could result in, the incurrence of substantial additional indebtedness and other expenses.
The Markets Served by the Company are Highly Competitive and this Competition Could Reduce Sales and Profit Margins.
Most of the Company’s products are sold in competitive markets. Maintaining and improving a competitive position will require continued investment in manufacturing, engineering, quality standards, marketing, technology, customer service and support and distribution networks. The Company may not be successful in maintaining its competitive position. The Company’s competitors may develop products that are superior, may develop methods of more efficiently and effectively providing products and services or may adapt quicker to new technologies or evolving customer requirements. Additionally, the Company’s competitors may adopt new technologies and technological advancements using artificial intelligence and machine learning to pursue new products and approaches more quickly, successfully and effectively than the Company. The Company may not be able to compete successfully with existing competitors or with new competitors. Pricing pressures may require the Company to adjust the prices of products to stay competitive. Failure to continue competing successfully could reduce sales, profit margins and overall financial performance.
The Company is Dependent on the Availability of Raw Materials, Parts and Components Used in Its Products and Changes in Supply of, or Price for, Raw Materials, Parts and Components May Materially Adversely Affect the Company.
While the Company manufactures certain parts and components used in its products, the Company also requires substantial amounts of raw materials and purchases certain parts and components from suppliers. The availability of and prices for raw materials, parts and components may be subject to curtailment or change due to, among other things, suppliers’ allocations to other purchasers, interruptions in production by suppliers, including due to geopolitical or civil unrest, unfavorable economic or industry conditions, labor disruptions, supply chain disruptions, catastrophic weather events, natural disasters, public health concerns, changes in exchange rates and prevailing price levels. Any change in the supply of, or price for, raw materials or parts and components could materially affect the Company and its financial condition, results of operations and cash flow.

The Company’s Business Operations May Be Materially Adversely Affected by Information Systems Interruptions or Intrusion, Including those Arising From Cybersecurity Attacks or Incidents or Violations of Laws Regulating Privacy and Data Security.
The Company depends on various internal and third party information technologies to administer, store, process and transmit electronic information (including sensitive or controlled data such as confidential business information and personal data relating to employees, customers and other business partners) and to support a variety of critical business activities. Our business has an increasing reliance on IT systems and a growing digital footprint as a result of changing technologies, increasing connected devices and digital offerings, and an increase in remote and hybrid workforce populations. Additionally, some of our products contain computer hardware and software and offer the ability to connect to computer networks. Our customers, including government customers, are also requiring cybersecurity protections and mandating cybersecurity standards for our businesses with more frequency. If the Company’s systems, technologies, products or services (including those we acquire through business acquisitions), or the systems, technologies, products or services of the Company’s customers or third-party hosting services (including third-party data centers and cloud platforms upon which we rely), are damaged or cease to function properly, or if the Company or third-party hosting service systems are subject to deliberate cyber-security attacks, such as those involving unauthorized access or malicious software, or unintentional cybersecurity incidents, such as those involving systems misconfigurations, misuse or human error and/or other intrusions, the Company, its operating results and financial condition could be materially adversely impacted. These impacts could include production downtimes, operational delays or other detrimental impacts on operations or the ability to provide products and services to customers; the compromise, destruction, corruption or theft of confidential or otherwise protected information, data or intellectual property; security breaches; other manipulation or improper use of the Company’s systems or networks; financial losses from fraudulent transactions; financial losses from remedial actions; loss of business or potential liability; adverse media coverage; legal claims or legal proceedings including regulatory investigations, actions, penalties or fines, including those arising from the violation of any applicable data privacy laws; and/or damage to the Company’s reputation. While we have experienced, and expect to continue to experience, these types of threats and incidents, based on our analysis at this time, we have not experienced a cybersecurity threat or incident that we believe has or is reasonably likely to materially affect the Company.
As a global organization, we are also subject to data privacy and security laws, regulations and customer-imposed controls in numerous jurisdictions as a result of having access to and processing confidential, personal and/or sensitive data in the course of our business. Governmental investigations and enforcement actions can be costly and interrupt the regular operations of our business, and data breaches or violations of data privacy laws can result in civil and criminal, monetary and non-monetary penalties and damages to our reputation, any of which may adversely affect our business and financial statements. As cybersecurity threats continue to evolve and as cybersecurity and data protection laws and regulations continue to develop globally, we expect to expend additional resources to continue to develop our compliance programs, strengthen our information security, data protection, disaster recovery and business continuity measures, and investigate and remediate vulnerabilities.
There has been a rise in the number of cyberattacks targeting confidential business information generally and in the manufacturing industry specifically by both state-sponsored and criminal organizations. These may include such things as denial of service attacks, introduction of ransomware or other malicious software programs, and other disruptive problems. In addition, there has been a rise in the number of cyberattacks that depend on human error or manipulation, including phishing attacks or schemes that use social engineering to gain access to systems or perpetuate wire transfer or other frauds. Moreover, the rapid evolution and increased adoption of artificial intelligence technologies may intensify our cybersecurity risks. These trends increase the likelihood of such events occurring.
The Company regularly identifies, defends against and responds to cyber threats and security incidents. While the Company attempts to mitigate cybersecurity risks by employing a number of measures, including employee training, technical security controls and maintenance of certain backup and protective systems, the Company’s systems, networks, products and services remain potentially vulnerable to known or unknown threats or other intrusions, and there are risks that our cybersecurity defenses will be insufficient to fully mitigate cyber risks and losses related to cybersecurity events, any of which may result in a material adverse effect on the Company and its financial condition or results of operations. Moreover, until we have migrated businesses we acquire onto our IT systems or ensured compliance with our information technology and cybersecurity standards, we have in the past and may in the future face additional risks because of the continued use of predecessor IT systems, procedures and cybersecurity risk mitigation measures. Given the unpredictability, nature and scope of cybersecurity attacks and incidents, it is possible that potential vulnerabilities could go undetected for an extended period, and it could take considerable time for the Company to obtain full and reliable information as to the extent, amount and type of information and/or systems compromised. Any imposition of liability, particularly liability that is not covered by insurance or is in excess of our insurance coverage, could materially adversely harm our operating results and financial condition.

Uncertainty Related to Environmental Regulation, Industry Standards, or Other Risks Associated with a Potential Global Transition to a Lower-Carbon Economy, as well as Physical Risks of Climate Change, Could Adversely Impact the Company's Results of Operations and Financial Position.
Increased public awareness and concern regarding environmental risks, including global climate change and the potential global transition to a lower-carbon economy, may result in more international, regional, federal and/or state requirements or industry standards to reduce or mitigate global warming and other environmental risks. New climate change laws and regulations could require the Company to change its manufacturing processes or obtain substitute materials that may cost more or be less available for its manufacturing operations. Various jurisdictions in which the Company does business have implemented, or in the future could implement or amend, restrictions on emissions of carbon dioxide or other greenhouse gases, taxation of or caps on the use of carbon-based energy, limitations or restrictions on water use, limitations or restrictions on the production of single use plastics, regulations on energy management and waste management and other rules and regulations to address climate change and other environmental risks, which may increase the Company’s expenses and adversely affect its operating results. In addition to changes in regulations or industry standards, a failure by the Company to innovate and adapt products to new markets, changing customer preferences for higher-efficiency products, or increasing scrutiny around fossil fuels usage could limit sales growth and negatively impact the Company and its financial condition, results of operations and cash flow.
The physical risks of climate change are highly uncertain and differ in the geographic regions in which the Company operates. These physical risks, including wildfires, rising sea levels, floods and other extreme weather events, may impact the availability and cost of materials, sources and supply of energy, product demand and manufacturing and could increase insurance and other operating costs. Any future increased worldwide regulatory activity relating to climate change could expand the nature, scope and complexity of matters that the Company is required to control, assess and report. If environmental laws or regulations or industry standards are either changed or adopted and impose significant operational restrictions and compliance requirements upon the Company, its suppliers, its customers or its products, or the Company's operations are disrupted due to physical impacts of climate change on the Company, its customers or its suppliers, the Company's business, results of operations and financial condition could be adversely impacted. Further, any failure to adequately address stakeholder expectations or to achieve previously announced initiatives or goals with respect to sustainability or environmental, social and governance matters may adversely impact our reputation, business, financial condition and results of operations.
Business Disruptions Due to Catastrophic Weather Events, Natural Disasters and Public Health Threats Could Adversely Affect the Company.
The Company faces various risks related to the occurrence of catastrophic weather events or significant natural disasters, including earthquakes, wildfires, droughts, fires, power-outages or other catastrophic events, in areas in which we have manufacturing facilities or from which we obtain products. Severe weather conditions, including any that may be caused or exacerbated by global climate change, may cause physical damage to our properties, closure of one or more of our manufacturing or distribution facilities, lack of an adequate work force in a market, temporary disruption in the supply of inventory, disruption in the transport of products and utilities and delays in the delivery of products to our customers.
Additionally, public health threats may negatively impact the global economy by causing changes in consumer behavior, market downturns, restrictions on business and individual activities and increased volatility. Any widespread public health threats could have a significant impact on the Company’s supply chain, such as the Company experienced during the global outbreak of the COVID-19 pandemic.
To the extent that any of the foregoing adversely affect the Company and its financial results, they may also have the effect of heightening many of the other risks described in Item 1A, “Risk Factors” of this annual report, such as those relating to international operations, the Company’s ability to develop new products, the Company’s ability to execute on its growth strategy of acquisitions, the Company’s dependency on raw materials, parts and components, the effects on movements in foreign currency exchange rates on the Company, the effects on the Company that result from declines in commodity prices and the Company’s reliance on labor availability to operate and grow the business.
Risks Related to Economic and Political Conditions
A Slowdown in the U.S. or International Economy Could Materially Adversely Affect the Sales and Profitability of the Company’s Businesses.
In 2023, 50% of the Company’s sales were derived from domestic operations and 50% were derived from international operations. The Company’s largest end markets include industrial, fire and safety, energy, life sciences, water and wastewater treatment, semiconductor, automotive, analytical instruments, food and pharmaceuticals, paint, agriculture and chemical

processing. A slowdown in the U.S. or global economy and, in particular, any of these specific end markets could materially reduce the Company’s sales and profitability.
Changes to Geopolitical and Economic Conditions in the U.S. and Foreign Countries in Which the Company Operates Could Adversely Affect the Company.
The Company expects international operations and export sales to continue to be significant for the foreseeable future. The Company’s sales from international operations and sales from export are both subject in varying degrees to risks inherent in doing business outside the U.S. These risks include the following:
•possibility of unfavorable circumstances arising from host country laws or regulations and the risks related to required compliance with local laws;
•risks of economic instability, including due to inflation;
•currency exchange rate fluctuations and restrictions on currency repatriation;
•potential negative consequences from changes to taxation policies;
•disruption of operations from labor and political disturbances;
•withdrawal from or renegotiation of international trade agreements and other restrictions on the trade between the United States and other countries;
•the imposition of and changes in the United States’ and other governments’ trade regulations, trade wars, tariffs and other trade barriers, including as a result of geopolitical developments (such as escalating tensions in the Middle East) and relations between the United States and China and the United States and Russia; and
•geopolitical events, including natural disasters, catastrophic weather events, climate change, public health conditions, including epidemics, pandemics and other outbreaks (such as the global outbreak of the COVID-19 pandemic), political instability or other geopolitical events, including civil or political unrest, terrorism, insurrection or war.
Any of these events could have a materially adverse impact on the Company and its operations.
Significant Movements in Foreign Currency Exchange Rates May Harm the Company’s Financial Results.
The Company is exposed to fluctuations in foreign currency exchange rates, particularly with respect to the Euro, Swiss Franc, Canadian Dollar, British Pound, Indian Rupee, Chinese Renminbi, Swedish Krona and Brazilian Real. Any significant change in the value of the currencies of the countries in which the Company does business against the U.S. Dollar could affect the Company’s ability to sell products competitively and control its cost structure, which could have a material adverse effect on results of operations. For additional detail related to this risk, see Part II, Item 7A, “Quantitative and Qualitative Disclosures About Market Risk.”
Fluctuations in Interest Rates Could Adversely Affect the Company’s Results of Operations and Financial Position.
The Company’s profitability may be adversely affected during any periods of unexpected or rapid increases in interest rates. The Company maintains a Credit Agreement with a revolving credit facility (the “Revolving Facility”) in an aggregate principal amount of $800 million and a term credit facility (the “Term Facility”) in an aggregate principal amount of $200 million (together, the “Credit Facility”), which bears interest at either an alternate base rate or adjusted Term SOFR (or appropriate alternative currency reference rates) plus, in each case, an applicable margin based on the lower of the Company’s senior, unsecured, long-term debt rating or the Company’s applicable leverage ratio. A significant increase in Term SOFR or the other rates the Company has agreed to use as an alternative to Term SOFR (should Term SOFR become unavailable) under the Credit Facility, as amended, would significantly increase the Company’s cost of borrowings. Further, any changes in regulatory standards or industry practices, such as the discontinuation of the use of Term SOFR and/or the transition to alternative benchmark rates may result in the usage of higher interest rates under the Credit Facility, and the Company’s current or future indebtedness may be adversely affected. The Company is also exposed to risks if the U.S. Federal Reserve raises its benchmark interest rate, which may reduce the availability of and increase the cost of obtaining new debt and refinancing existing indebtedness. For additional detail related to this risk, see Part II, Item 7A, "Quantitative and Qualitative Disclosures About Market Risk."

A Significant or Sustained Decline in Commodity Prices, Including Oil, Could Negatively Impact the Levels of Expenditures by Certain of the Company’s Customers.
Demand for the Company’s products depends, in part, on the level of new and planned expenditures by certain of its customers. The level of expenditures by the Company’s customers is dependent on, among other factors, general economic conditions, availability of credit, economic conditions within their respective industries and expectations of future market behavior. Volatility in commodity prices, including oil, can negatively affect the level of these activities and can result in postponement of capital spending decisions or the delay or cancellation of existing orders. The ability of the Company’s customers to finance capital investment and maintenance may also be affected by the conditions in their industries. Reduced demand for the Company’s products could result in the delay or cancellation of existing orders or lead to excess manufacturing capacity, which unfavorably impacts the absorption of fixed manufacturing costs. This reduced demand could have a material adverse effect on the Company and its financial condition and results of operations.
Risks Related to Legal, Accounting and Regulatory Matters
An Unfavorable Outcome of Any Pending Contingencies or Litigation Could Adversely Affect the Company.
The Company is currently involved in pending and threatened legal, regulatory and other proceedings arising in the ordinary course of business. These proceedings may pertain to matters such as product liability or contract disputes, and may also involve governmental inquiries, inspections, audits or investigations relating to issues such as tax matters, intellectual property, environmental, health and safety issues, governmental regulations, employment and other matters. Where it is reasonably possible to do so, the Company accrues estimates of the probable costs for the resolution of these matters. These estimates are developed in consultation with outside counsel and are based upon an analysis of potential results and the availability of insurance coverage, assuming a combination of litigation and settlement strategies. It is possible, however, that future operating results for any particular quarter or annual period could be materially affected by changes in assumptions, the continued availability of insurance coverage or the effectiveness of the Company’s strategies related to these proceedings. For additional detail related to this risk, see Item 3, “Legal Proceedings” and Note 10 in Part II, Item 8, “Financial Statements and Supplementary Data.”
Failure to Adequately Protect the Company’s Intellectual Property and the Risk of Disputes Involving Intellectual Property Infringement Could Adversely Impact the Company’s Competitive Position, Results of Operations, and Financial Condition.
The Company owns patents, trademarks, licenses and other forms of intellectual property related to its products and continuously invests in research and development that may result in technological innovations and general intellectual property rights. The Company employs various measures to develop, maintain and protect its intellectual property rights. If these measures are not effective, or if the Company’s intellectual property is otherwise infringed, challenged, invalidated or circumvented, the Company may face adverse impacts to its results of operations and/or financial condition. Further, if intellectual property is infringed, challenged, invalidated or circumvented, this could reduce barriers to entry into the Company’s existing lines of business and may result in a loss of market share and adversely impact the Company’s competitive position. Additionally, the Company has registered intellectual property in multiple countries, and the Company’s ability to protect and enforce its intellectual property rights may be limited in foreign countries due to differences in intellectual property protections or proprietary rights laws. If the Company’s intellectual property is infringed, challenged, invalidated or circumvented due to these lesser protections, the Company may face adverse impacts to its results of operations, financial condition and/or competitive position.
Litigation may be necessary to enforce the Company’s intellectual property rights or to defend against infringement claims by third parties. Any litigation or claims brought by the Company could result in costs and diversion of resources, which could adversely affect the Company’s results of operations and/or financial condition. Any intellectual property litigation or claims brought against the Company may lead to litigation expenses, diversion of resources, losses or licensing expenses or the cessation of selling certain products, any of which could adversely affect the Company’s results of operations and/or financial condition.
The Company’s Intangible Assets, Including Goodwill, are a Significant Portion of Total Assets and a Write-off of Intangible Assets or Goodwill Would Adversely Impact the Company’s Operating Results and Significantly Reduce the Company’s Net Worth.
The Company’s total assets includes substantial intangible assets, primarily goodwill and identifiable intangible assets, which primarily result from acquisitions. At December 31, 2023, goodwill and intangible assets totaled $2,838.3 million and
19

Table of Contents
$1,011.8 million, respectively. Annually, or when certain events occur that require a more current valuation, the Company assesses whether there has been an impairment in the value of goodwill and identifiable intangible assets. If future operating performance at one or more of the Company’s reporting units were to fall significantly below forecasted levels, the Company could be required to reflect, under current applicable accounting rules, a non-cash charge to operating income for an impairment. Any determination requiring the write-off of a significant portion of goodwill or identifiable intangible assets would adversely impact the Company’s results of operations and net worth. See Note 6 in Part II, Item 8, “Financial Statements and Supplementary Data” for further discussion on goodwill and intangible assets.
The Company May Face Adverse Effects Resulting from Improper Conduct by Our Employees, Agents or Business Partners.
While we strive to maintain high standards, the Company cannot guarantee that our internal controls and compliance systems will always protect us from reckless or criminal acts committed by employees, agents or business partners of ours (or businesses that we acquire or partner with) that would violate laws in the U.S. or foreign countries in which the Company operates, including laws governing payment to government officials, bribery, fraud, conflicts of interest, competition, employment practices and workplace behavior, export and import compliance, economic and trade sanctions, money laundering and data privacy.
In particular, recent years have seen a substantial increase in anti-bribery law enforcement activity with more frequent and aggressive investigations and enforcement proceedings by both the Department of Justice and the SEC, increased enforcement activity by non-U.S. regulators and increases in criminal and civil proceedings brought against companies and individuals. The Company’s policies mandate compliance with all anti-bribery laws, including the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and similar anti-bribery laws in other jurisdictions which generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business. However, the Company operates in certain countries that are recognized as having governmental and commercial corruption. Violations of any of these laws may result in criminal or civil sanctions or penalties, both monetary and non-monetary, increased costs of compliance and/or damage to our reputation, any of which could have a material adverse effect on the Company and its financial condition and results of operations.
General Risk Factors
A Failure to Retain Executive Management and Key Personnel or Recruit Adequate Successors May Adversely Affect the Company’s Operations and Implementation of Strategy.
The Company’s future success depends to a significant degree on the skills, experience and efforts of its executive management and other key personnel and their ability to provide the Company with uninterrupted leadership and direction. The loss of the services of any of the executive officers or other key personnel or a failure to provide adequate succession plans for these individuals could have an adverse impact on the Company’s operations and implementation of its strategic plan. The availability of highly qualified talent is limited and the competition for talent is robust.
Challenges with Respect to Labor Availability Could Negatively Impact the Company’s Ability to Operate or Grow the Business.
The Company’s success depends in part on the ability of its businesses to proactively attract, motivate and retain a qualified and highly skilled workforce in an intensely competitive labor market. A failure to attract, motivate and retain highly skilled personnel could adversely affect the Company’s operating results or its ability to operate or grow the business. Additionally, any labor stoppages or labor disruptions, including due to geopolitical unrest, unfavorable economic or industry conditions, catastrophic weather events, natural disasters or public health threats could adversely affect the Company’s operating results or its ability to operate or grow the business.

Item 1C. Cybersecurity.
Risk Management and Strategy.
The Company’s cybersecurity program is designed to be aligned to the Cybersecurity Framework published by the National Institute of Standards and Technology (“NIST CSF”). While we use the NIST CSF as a guide, this does not imply that we meet any particular standards, specifications or requirements. We conduct regular internal and external assessments of our information security and cybersecurity programs, including periodic external audits for company-wide compliance with our program as well as specific business unit alignment, as required, with U.S. federal acquisition regulations and UK Cyber Essentials certifications. An external penetration test is performed annually against the Company’s network, in addition to our regular internal vulnerability scans.
The Company’s internal Incident Response Policy sets forth specific protocols for cyber or data incident identification, detection, response and recovery. This process includes the assembly of a response team consisting of internal and external technical and legal experts immediately upon the event of a cyberattack or incident. The Company reviews and updates this process regularly, including by engaging in tabletop exercises to simulate cybersecurity and data breach incidents. The Company maintains global cybersecurity insurance coverage that is reviewed annually for adequacy against operations and information systems.
The Company has implemented a number of measures to mitigate cybersecurity risk in its operations, including annual cybersecurity awareness training for employees, regular internal phishing exercises, technical security controls, maintenance of certain backup and protective systems, physical and system securities measures, and data security protocols. Once fully integrated, all of our businesses have access to a “cyber risk dashboard” that monitors various risk indicators. The cyber risk dashboard is monitored by our business units. The Company’s internal auditors periodically review and audit various processes and controls throughout the organization related to cybersecurity readiness.
The Company also has certain processes in place to manage cyber risks associated with third-party service providers which include various technical as well as contractual measures.
For more information on cybersecurity risks and how they affect our business, operating results and financial condition, please refer to Item 1 A., “Risk Factors – The Company’s Business Operations May Be Materially Adversely Affected by Information Systems Interruptions or Intrusion, Including those Arising From Cybersecurity Attacks or Incidents or Violations of Laws Regulating Privacy and Data Security.” Based on our analysis at this time, we have not identified any risks from a cybersecurity threat or incident that we believe has or is reasonably likely to materially affect the Company.
Governance, Oversight and Leadership.
The Board and the Audit Committee oversee management’s efforts to address cybersecurity and information security risks. Senior management provides the Board updates on the Company’s cybersecurity program at least once a year, including as part of the Company’s enterprise risk management assessment, and the Audit Committee reviews the cybersecurity program at least twice a year and on an as-needed basis. Such reviews, among other things, include the results of internal and/or external assessments, a review of cybersecurity governance at the management level, and a review of the Company’s cybersecurity program and progress toward various initiatives.
The Company also maintains an Executive Cybersecurity Steering Committee (the “Cybersecurity Committee”), made up of key members of senior leadership, to oversee and monitor progress of various cybersecurity initiatives throughout the organization. The Cybersecurity Committee meets quarterly. In addition, the Company asks each business unit to designate an employee as the local Information Security Officer responsible for monitoring the business unit’s cyber risk dashboard and coordinating with local leadership to respond to identified risks accordingly. Each local Information Security Officer completes an annual certification process and receives regular updates with respect to the Company’s cybersecurity program.
The Chief Information Officer (“CIO”), who reports to the Chief Financial Officer, along with members of the corporate and business unit information technology teams, are generally responsible for developing and managing the Company’s cybersecurity programs. Our CIO has over 20 years of experience in various information technology and information security roles, and our information security team is comprised of employees with broad knowledge of cybersecurity issues gained through experience and through training and certifications. These individuals, along with other internal and external personnel as needed, monitor the prevention, detection, mitigation and remediation of cybersecurity incidents, and applicable personnel are informed of known cybersecurity incidents to form the appropriate incident response team and respond accordingly.

Item 2. Properties.
The Company conducts business at plants and offices that can be owned or leased and located in the U.S. or outside the U.S., with square footage primarily in Germany (12%), India (8%), the Netherlands (6%), the U.K. (6%), Italy (3%), Canada (3%), China (2%) and Switzerland (1%). Management considers its facilities suitable and adequate for the Company’s operations and believes it has ample capacity in its plants and equipment to meet demand increases for future growth in the intermediate term, especially given its operational improvement initiatives that usually increase capacity.
A summary of properties used by the Company’s operations as of December 31, 2023 are shown in the following table:

|  | Square footage (in millions)
|  |  |  | Location |  | Owned/Leased
|  | Total |  | Domestic |  | International |  | Owned |  | Leased
Fluid & Metering Technologies |  | 2.0 |  |  | 1.4 |  |  | 0.6 |  |  | 1.4 |  |  | 0.6 |
Health & Science Technologies |  | 2.1 |  |  | 1.1 |  |  | 1.0 |  |  | 0.5 |  |  | 1.6 |
Fire & Safety/Diversified Products |  | 1.1 |  |  | 0.6 |  |  | 0.5 |  |  | 1.0 |  |  | 0.1 |
Other(1) |  | 0.6 |  |  | 0.1 |  |  | 0.5 |  |  | 0.4 |  |  | 0.2 |
Total |  | 5.8 |  |  | 3.2 |  |  | 2.6 |  |  | 3.3 |  |  | 2.5 |

(1) Other includes shared service locations as well as the Company’s executive office, which occupies 40,261 square feet of leased space in Northbrook, Illinois and 16,268 square feet of leased space in Chicago, Illinois.
Item 3. Legal Proceedings.
The Company and its subsidiaries are party to legal proceedings arising in the ordinary course of business as described in Note 10 in Part II, Item 8, “Financial Statements and Supplementary Data,” and such disclosure is incorporated by reference into this Item 3, “Legal Proceedings.”
The Company's threshold for disclosing material environmental legal proceedings involving a government authority where potential monetary sanctions are involved is $1.0 million.
In addition, the Company and six of its subsidiaries are presently named as defendants in a number of lawsuits claiming various asbestos-related personal injuries, allegedly as a result of exposure to products manufactured with components that contained asbestos. These components were acquired from third party suppliers and were not manufactured by the Company or any of the defendant subsidiaries. To date, the majority of the Company’s settlements and legal costs, except for costs of coordination, administration, insurance investigation and a portion of defense costs, have been covered in full by insurance, subject to applicable deductibles. However, the Company cannot predict whether and to what extent insurance will be available to continue to cover these settlements and legal costs, or how insurers may respond to claims that are tendered to them. Asbestos-related claims have been filed in jurisdictions throughout the United States and the United Kingdom. Most of the claims resolved to date have been dismissed without payment. The balance of the claims have been settled for various immaterial amounts. Only one case has been tried, resulting in a verdict for the Company’s business unit. No provision has been made in the financial statements of the Company, other than for insurance deductibles in the ordinary course, and the Company does not currently believe the asbestos-related claims will have a material adverse effect on the Company’s business, financial position, results of operations or cash flows.
Item 4. Mine Safety Disclosures.
Not applicable.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion and analysis should be read in conjunction with the Company’s Consolidated Financial Statements and related notes in this annual report. This discussion may contain forward-looking statements based upon current expectations that involve risks and uncertainties. The Company’s actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those set forth under Item 1A, “Risk Factors” and under the heading “Cautionary Statement Under the Private Securities Litigation Reform Act” discussed elsewhere in this annual report.
This discussion includes certain non-GAAP financial measures that have been defined and reconciled to their most directly comparable financial measure prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) under the headings “Non-GAAP Disclosures” and “Free Cash Flow.” This discussion also includes Operating working capital which has been defined under the heading “Liquidity and Capital Resources.” The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures prepared in accordance with U.S. GAAP. The financial results prepared in accordance with U.S. GAAP and the reconciliations from these results should be carefully evaluated.
2023 Overview
IDEX is an applied solutions provider specializing in the manufacture of fluid and metering technologies, health and science technologies and fire, safety and other diversified products built to customers’ specifications. IDEX’s products are sold in niche markets across a wide range of industries throughout the world. Accordingly, IDEX’s businesses are affected by levels of industrial activity and economic conditions in the U.S. and in other countries where it does business, as well as by the relationship of the U.S. dollar to other currencies. Levels of capacity utilization and capital spending in certain industries and overall industrial activity are important factors that influence the demand for IDEX’s products.
During 2023, the Company delivered strong operating performance amid sharp volume declines as customers recalibrated inventory levels and order patterns following the easing of global supply chain constraints and reduced lead times. While customer inventory destocking resulted in lower sales volumes, most prominently experienced by the Company’s Health & Science Technologies segment, the Company realized strong price/cost and achieved favorable operational productivity across its segments. Net income attributable to IDEX and Adjusted EBITDA were $596.1 million and $899.6 million, respectively, in 2023, both up 2% from the prior year. Cash flows from operating activities were $716.7 million during the year ended December 31, 2023, reflecting inventory reduction efforts and resulting in record free cash flow of $626.8 million during the year. Finally, the Company deployed capital with the acquisition of two businesses – Iridian Spectral Technologies (“Iridian”) and STC Material Solutions (“STC”).

2024 Outlook
Moving into 2024, the majority of our businesses are currently experiencing stable demand and seeing early signs of improvement, particularly in the Fluid & Metering Technologies segment. However, while the life sciences and analytical instrumentation markets served by approximately one-third of the Health & Science Technologies segment appear stable, these markets are not yet showing signs of near-term recovery. We continue to believe in the long-term growth potential of these end markets and believe we are well positioned to support growth as demand increases. Additionally, we expect the Dispensing reporting unit within the Company’s Fire & Safety/Diversified Products segment to contract in 2024, due to the completion of the fleet refreshment cycle of our North American customers in 2023. These declines are expected to be partly offset by growth in the Dispensing reporting unit in emerging markets and growth in the Fire & Safety and BAND-IT reporting units.

Diluted earnings per common share attributable to IDEX | $ | 7.85 |  | $ | 7.71 |  |  | $ | 0.14 |  |  | 2 | %

Net Sales
Net sales increased 3% as compared to the prior year, driven by a 5% increase in acquisitions, net of divestitures, partially offset by a 1% decrease in organic sales and a 1% decrease due to the acceleration of previously deferred revenue related to the exit of a COVID-19 testing application in 2022 that did not reoccur in 2023 (see Note 14 in the Notes to Consolidated Financial Statements for further detail). The decrease in organic sales was driven by lower volumes as a result of market conditions during the year, particularly in the Health & Science Technologies businesses, partially offset by price capture across all segments. Net sales decreased 1% domestically and increased 7% internationally, and sales to customers outside the U.S. were approximately 50% of total sales in 2023 compared with 48% in 2022.
Gross Profit and Gross Margin
Gross profit and Gross margin were positively impacted by price/cost and strong operational productivity as well as lower fair value inventory step-up charges, and negatively impacted by lower volume leverage, higher employee-related costs, unfavorable mix and the acceleration of previously deferred revenue related to the exit of a COVID-19 testing application in 2022 that did not reoccur in 2023. While acquisitions, net of divestitures also positively impacted Gross profit, they resulted in a dilutive impact to overall Gross margin.
Selling, General and Administrative Expenses
Selling, general and administrative expenses increased primarily due to the $49.1 million impact from acquisitions, including amortization, net of divestitures, as well as increases in employee-related costs, which were largely offset by a decrease in variable compensation.
27

Table of Contents
Restructuring Expenses and Asset Impairments
Restructuring expenses and asset impairments decreased primarily due to an asset impairment charge of $16.8 million related to the exit of a COVID-19 testing application in 2022, partially offset by higher severance costs in 2023 incurred in conjunction with cost mitigation efforts as a result of current market conditions. See Note 14 in the Notes to the Consolidated Financial Statements for further detail.
Gain on Sale of Businesses - Net
In 2023, the Company completed the sale of Micropump for proceeds of $110.3 million, net of cash remitted, which resulted in a pre-tax gain of $93.8 million, and the sale of Novotema, SpA (“Novotema”) for proceeds of $8.3 million, net of cash remitted, which resulted in a loss of $9.1 million. In 2022, the Company completed the sale of Knight LLC (“Knight”) for proceeds of $49.4 million, net of cash remitted, which resulted in a pre-tax gain of $34.8 million.
Other Expense (Income) - Net
Other expense (income) - net was $5.2 million of expense in 2023 compared to $3.9 million of income in 2022. The increase in expense was primarily due to a $7.7 million credit loss reserve on an investment with a collaborative partner (see Note 3 in the Notes to Consolidated Financial Statements for further detail), higher foreign currency transaction losses and $2.7 million of gains on the sale of assets in 2022 that did not reoccur in 2023, partially offset by higher interest earned on cash balances and gains on the sale of trading securities in 2023.
Interest Expense
Interest expense increased primarily due to the borrowings incurred under the Credit Facility in connection with the acquisition of Muon B.V. and its subsidiaries (“Muon Group”) in November 2022 as well as higher interest rates on the Company’s indebtedness.
Income Taxes
The Company’s provision for income taxes is based upon estimated annual tax rates for the year applied to federal, state and foreign income. The provision for income taxes increased $2.0 million to $164.7 million in 2023 as compared with $162.7 million in 2022. The 2023 effective tax rate of 21.7% remained unchanged compared with the 2022 effective tax rate.
In October 2021, members of the Organization for Economic Co-operation and Development (“OECD”) and G20 Inclusive Framework on Base Erosion and Profit Shifting agreed to a two-pillar solution to address the tax challenges associated with the digitalization of the economy. In December 2021, the OECD released the Pillar Two Model Rules (“Pillar Two”), which define the global minimum tax and call for the taxation of large corporations at a minimum rate of 15%. Although it is uncertain when and how the rules will be fully enacted into law, based on our initial assessment, nearly all of the jurisdictions in which the Company operates have an effective tax rate above the 15% threshold. Therefore, the Company does not expect a material impact from the Pillar Two income tax rules.
Results of Reportable Business Segments
The Company has three reportable segments: Fluid & Metering Technologies (“FMT”), Health & Science Technologies (“HST”) and Fire & Safety/Diversified Products (“FSDP”). For a detailed description of the operations within each segment, please refer to Part I, Item 1, “Business” of this Annual Report on Form 10-K.
Management’s primary measurements of segment performance are Net sales, adjusted earnings before interest, income taxes, depreciation and amortization (“Adjusted EBITDA”) and Adjusted EBITDA margin.

(“KZValve”) results for the first four months of 2023 are reflected in the acquisitions/divestitures column while the remaining year-over-year impact is included in the organic column.
(2) Divestitures included Knight sold in September 2022.
•Organic net sales were positively impacted by the following:
◦Water reporting unit driven by price capture, favorability in the municipal water market and operational execution;
◦Energy reporting unit driven by operational execution related to backlog reduction, improved supply chain conditions, price capture and growth initiatives;
◦Valves reporting unit driven by strong price capture and demand in Asia; and
◦Pumps reporting unit driven by strong price capture and operational execution, which more than offset the impact of lower volumes in the industrial market.
Organic net sales were negatively impacted by the Agriculture reporting unit driven by distribution inventory recalibration, partially offset by positive original equipment manufacturer demand.
•The increase in Adjusted EBITDA margin was primarily due to strong price/cost and operational productivity, partially offset by higher employee-related costs, unfavorable mix and lower volume leverage.

(1) Based on the timing of the acquisition, Muon Group results for the first 10.5 months of 2023 are reflected in the acquisitions/divestitures column while the remaining year-over-year impact is included in the organic column.
(2) Acquisitions included Iridian acquired in May 2023 and STC acquired in December 2023. Divestitures included Micropump sold in August 2023 and Novotema sold in December 2023.
(3) Change in Net sales includes the acceleration of previously deferred revenue of $17.9 million as a result of a customer’s decision to discontinue further investment in commercializing its COVID-19 testing application in 2022 that did not reoccur in 2023, the impact of which was excluded from Adjusted net sales. See Note 14 in the Notes to Consolidated Financial Statements for further detail.

•The decrease in organic net sales was attributed to the following:
◦Scientific Fluidics & Optics reporting unit driven by lower demand from analytical instrumentation and life science original equipment manufacturers due to customer inventory recalibration and market slowing, partially offset by price capture and strong cost control;
◦Sealing Solutions reporting unit driven by lower volumes in the semiconductor market;
◦Material Processing Technologies reporting unit driven by lower volumes in the pharmaceuticals/biopharmaceuticals and food markets, partially offset by operational execution related to backlog reduction and price capture; and
◦Performance Pneumatics Technologies reporting unit driven by the impact of lower volumes in the industrial market, partially offset by targeted growth performance and price capture.
•The decrease in Adjusted EBITDA margin was primarily due to lower volume leverage, higher employee-related costs and unfavorable mix, partially offset by strong operational productivity and price/cost.

•Organic net sales were positively impacted by the following:
◦Fire & Safety reporting unit driven by price capture, continued demand for rescue tools, improved supply chain conditions and operational execution; and
◦BAND-IT reporting unit driven by continued share gain in an otherwise flat automotive market.
Organic net sales had no impact from the Dispensing reporting unit as organic sales were flat. Price capture was fully offset by lower volumes.
•The increase in Adjusted EBITDA margin was primarily due to strong price/cost and favorable operational productivity, partially offset by higher employee-related costs.
Liquidity and Capital Resources
Liquidity
Based on management’s current expectations and currently available information, the Company believes current cash, cash from operations and cash available under the Revolving Facility will be sufficient to meet its operating cash requirements, planned capital expenditures, interest and principal payments on all borrowings, pension and postretirement funding requirements, share repurchases and quarterly dividend payments to holders of the Company’s common stock for the foreseeable future. Additionally, in the event that suitable businesses are available for acquisition upon acceptable terms, the Company may obtain all or a portion of the financing for these acquisitions through the incurrence of additional borrowings.

Operating Working Capital
Operating working capital, calculated as Receivables - net plus Inventories - net minus Trade accounts payable, is used by management as a measurement of operational results as well as the short-term liquidity of the Company. The following table details Operating working capital as of December 31, 2023 and 2022:

(In millions) |  | December 31, 2023 |  | December 31, 2022 |  | Change |  | Organic Change
Receivables - net |  | $ | 427.8 |  |  | $ | 442.8 |  |  | $ | (15.0) |  |  | $ | (15.6) |
Inventories - net |  | 420.8 |  |  | 470.9 |  | (50.1) |  |  | (62.8) |
Less: Trade accounts payable |  | 179.7 |  |  | 208.9 |  |  | 29.2 |  |  | 25.0 |
Operating working capital |  | $ | 668.9 |  |  | $ | 704.8 |  |  | $ | (35.9) |  |  | $ | (53.4) |

Operating working capital decreased $35.9 million to $668.9 million at December 31, 2023. Acquisitions, divestitures and foreign currency translation increased Operating working capital by $17.5 million during 2023. Apart from these items, reduced inventory levels were partly offset by lower levels of accounts payable, and strong price capture partially offset the impact of lower volume on receivables.

Cash Flow Summary
The following table is derived from the Consolidated Statements of Cash Flows:

|  | Year Ended December 31,
(In millions) |  | 2023 |  | 2022
Net cash flows provided by (used in): |  |  |  |
Operating activities |  | $ | 716.7 |  |  | $ | 557.4 |
Investing activities |  | (283.8) |  |  | (917.2) |
Financing activities |  | (344.7) |  |  | (37.8) |

Operating Activities
Cash flows provided by operating activities increased $159.3 million to $716.7 million in 2023 primarily due to lower working capital requirements in 2023 as a result of efforts to recalibrate inventory levels in response to normalizing market conditions. The prior year period included higher working capital requirements related to higher volumes and increased inventories to support production amid supply chain challenges.
Investing Activities
Cash flows used in investing activities decreased in 2023 primarily due to the purchase of Iridian and STC in 2023 for $311.8 million as compared with the purchases of Nexsight, KZValve and Muon Group in 2022 for $945.6 million as well as proceeds of $118.6 million in 2023 from the sales of Micropump and Novotema as compared with $49.4 million in 2022 from the sale of Knight. These items were partially offset by higher capital expenditures of $89.9 million in 2023 as compared with $68.0 million in 2022.
Financing Activities
Cash flows used in financing activities in 2023 primarily consisted of dividends of $190.7 million paid to common shareholders, payments of $150.0 million on the Term Facility, and the repurchase of shares for $24.2 million. Additionally, in 2023, proceeds of $100.0 million from the issuance of the 5.13% Senior Notes were used to redeem the $100.0 million of the Company’s 3.20% Senior Notes due June 13, 2025 (the “3.20% Senior Notes”) outstanding. Cash flows used in financing activities in 2022 primarily consisted of dividends of $177.4 million paid to common shareholders and the repurchase of shares for $148.1 million. These outflows were partially offset by net proceeds of $75.4 million under the Revolving Facility and $200.0 million under the Term Facility, which were used to fund the Muon Group acquisition.
Free Cash Flow
The Company believes free cash flow, a non-GAAP measure, is an important measure of performance because it provides a measurement of cash generated from operations that is available for payment obligations such as operating cash requirements, planned capital expenditures, interest and principal payments on all borrowings, pension and postretirement funding requirements and quarterly dividend payments to holders of the Company’s common stock as well as for funding acquisitions and share repurchases. Free cash flow is calculated as cash flows provided by operating activities less capital expenditures.
The following table reconciles free cash flow to cash flows provided by operating activities:

|  | Year Ended December 31,
(Dollars in millions) |  | 2023 |  | 2022
Cash flows provided by operating activities |  | $ | 716.7 |  | $ | 557.4
Less: capital expenditures |  | 89.9 |  | 68.0
Free cash flow |  | $ | 626.8 |  | $ | 489.4
Free cash flow as a percent of adjusted net income attributable to IDEX |  | 101 | % |  | 79 | %

The increase in free cash flow as compared to 2022 is due to lower working capital requirements in 2023 discussed above as compared with 2022, partially offset by higher capital expenditures.

Covenants
The key financial covenants that the Company is required to maintain in connection with the Revolving Facility, the Term Facility, the 3.37% Senior Notes and the 5.13% Senior Notes, are a minimum interest coverage ratio of 3.0 to 1 and a maximum leverage ratio of 3.50 to 1. At December 31, 2023, the Company was in compliance with both of these financial covenants, as the Company’s interest coverage ratio was 18.43 to 1 for covenant calculation purposes and the leverage ratio was 1.45 to 1. There are no financial covenants relating to the 2.625% Senior Notes or the 3.00% Senior Notes; however, both are subject to cross-default provisions. For a discussion of the Company’s Revolving Facility and Senior Notes as well as the associated covenants, refer to Note 7 in the Notes to Consolidated Financial Statements.

Of the $10.5 million of letters of credit, only $3.4 million reduced the Company’s borrowing capacity under the Revolving Facility as of December 31, 2023.
Except as disclosed above, the Company has no off-balance sheet arrangements that currently have or are reasonably likely to have a material effect on the Company’s consolidated financial condition, changes in financial condition, results of operations, liquidity, capital expenditures or capital resources.
Critical Accounting Estimates
The Company believes that the application of the following accounting policy, which is important to its financial position and results of operations, requires significant judgments and estimates on the part of management. For a summary of the Company’s accounting policies, including the accounting policy discussed below, see Note 1 in the Notes to Consolidated Financial Statements.
Goodwill and indefinite-lived intangible assets — Goodwill and other intangible assets with indefinite lives, which consists solely of trade names, are not amortized; rather they are tested for impairment at least annually, or more frequently if events or circumstances indicate that the asset may be impaired. The Company follows the guidance prescribed in Accounting Standards Codification (“ASC”) 350, Goodwill and Other Intangible Assets, to test goodwill and indefinite-lived intangible assets for impairment. In assessing goodwill for impairment, the Company determines the fair value of each reporting unit utilizing an income approach (discounted cash flows) weighted 50% and a market approach (consisting of a comparable public company multiples methodology) weighted 50%. To determine the reasonableness of the calculated fair values, the Company reviews the assumptions to ensure that neither the income approach nor the market approach yielded significantly different valuations. Key assumptions and estimates used in the goodwill impairment assessment are described below. Based on the results of the Company’s annual impairment test at October 31, 2023, all reporting units had fair values substantially in excess of their carrying values.
The key assumptions are updated every year for each reporting unit for the income and market approaches used to determine the fair value. Various assumptions are utilized including forecasted operating results, annual operating plans, strategic plans, economic projections, anticipated future cash flows, the weighted average cost of capital, market data and market multiples. The assumptions that have the most significant effect on the fair value calculations are the weighted average cost of capital, market multiples, forecasted EBITDA and terminal growth rates. The following assumption ranges were utilized by the Company in 2023 and 2022:

Assumptions | 2023 Range |  | 2022 Range
Weighted average cost of capital | 10.00% to 12.25% |  | 9.75% to 11.50%
Market multiples | 10.0x to 20.0x |  | 10.0x to 19.0x
Terminal growth rates | 3.0% to 3.5% |  | 2.5% to 3.5%

In assessing trade names for impairment, the Company uses the relief-from-royalty method, a form of the income approach, to determine the fair value of its trade names. The relief-from-royalty method is dependent on a number of significant management assumptions, including estimates of revenues, royalty rates and discount rates. Based on the results of the Company’s annual impairment test at October 31, 2023, the trade names had fair values in excess of their carrying values.
The Company’s acquisitions have generally included significant goodwill components and the Company expects to continue to make acquisitions. At December 31, 2023, goodwill and other indefinite-lived intangible assets totaled $2,929.2 million, or 50%, of the Company’s total assets.
See Note 6 in the Notes to Consolidated Financial Statements for further discussion on goodwill and indefinite-lived intangible assets.

Non-GAAP Disclosures
Set forth below are reconciliations of Organic net sales, Adjusted net sales, Adjusted gross profit, Adjusted gross margin, Adjusted net income attributable to IDEX, Adjusted diluted earnings per share (“EPS”) attributable to IDEX, Consolidated Adjusted earnings before interest, income taxes, depreciation and amortization (“Adjusted EBITDA”) and Consolidated Adjusted EBITDA margin to their respective most directly comparable U.S. GAAP measure. Management uses these metrics to measure performance of the Company since they exclude items that are not reflective of ongoing operations, as identified in the reconciliations below. Management also supplements its U.S. GAAP financial statements with adjusted information to provide investors with greater insight, transparency and a more comprehensive understanding of the information used by management in its financial and operational decision making.
Management uses Adjusted EBITDA as its principal measure of segment performance, and believes it is a useful indicator of the strength and performance of the Company and its segments’ ongoing business operations, as well as a way for investors to evaluate and compare operating performance and value companies within the Company’s industry. Management believes that Adjusted EBITDA margin is useful for the same reason as Adjusted EBITDA. The definition of Adjusted EBITDA used here may differ from that used by other companies.
This report also references free cash flow. This non-GAAP measure is discussed and reconciled to its most directly comparable GAAP measure in the section above titled “Free Cash Flow.”
The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures prepared in accordance with U.S. GAAP. Due to rounding, numbers presented throughout this and other documents may not add up or recalculate precisely. The financial results prepared in accordance with U.S. GAAP and the reconciliations from these results should be carefully evaluated.

(3) The impact to Net sales and Gross margin represents the acceleration of previously deferred revenue of $17.9 million as a result of a customer’s decision to discontinue further investment in commercializing its COVID-19 testing application in 2022 that did not reoccur in 2023, which was largely offset by an impairment charge during the same period resulting in a $1.1 million impact on net income. See Note 14 in the Notes to Consolidated Financial Statements for further detail.
(4) Represents a reserve recorded on an investment with a collaborative partner. See Note 3 in the Notes to Consolidated Financial Statements for further detail.
Item 7A. Quantitative and Qualitative Disclosures About Market Risk.
The Company is subject to market risk associated with changes in foreign currency exchange rates and interest rates as well as inflationary factors. The Company may, from time to time, enter into foreign currency forward contracts and interest rate swaps on its debt when it believes there is a financial advantage in doing so. A treasury risk management policy, adopted by the Board of Directors, describes the procedures and controls over derivative financial and commodity instruments, including foreign currency forward contracts and interest rate swaps. Under the policy, the Company does not use financial or commodity derivative instruments for trading purposes and the use of these instruments is subject to strict approvals by senior officers. Typically, the use of derivative instruments is limited to foreign currency forward contracts and interest rate swaps on the

Table of Contents
Company’s outstanding long-term debt. As of December 31, 2023, the Company did not have any derivative instruments outstanding.
Foreign Currency Exchange Rates
The Company’s foreign currency exchange rate risk is limited principally to the Euro, Swiss Franc, Canadian Dollar, British Pound, Indian Rupee, Chinese Renminbi, Swedish Krona and Brazilian Real. The Company manages its foreign exchange risk principally through invoicing customers in the same currency as the source of products. The foreign currency transaction losses (gains) for the periods ended December 31, 2023, 2022 and 2021 were $7.3 million, $(0.8) million and $1.1 million, respectively, and are reported within Other expense (income) - net on the Consolidated Statements of Income. See Note 1 in the Notes to Consolidated Financial Statements for further discussion.
Interest Rate Fluctuations
The Company has interest rate exposure due to $131.0 million of the $1,333.3 million debt outstanding at December 31, 2023 being floating rate debt. The Company’s Revolving Facility and Term Facility both bear interest at either an alternate base rate or adjusted Term SOFR (or appropriate alternative currency reference rates) plus, in each case, an applicable margin based on the lower of the Company’s senior, unsecured, long-term debt rating or the Company’s applicable leverage ratio. At December 31, 2023, there was $81.0 million outstanding under the Revolving Facility with an interest rate of 5.00% and $50.0 million outstanding under the Term Facility with an interest rate of 6.59%.
Inflation Risk
We source a wide variety of materials and components from a network of global suppliers. While materials are typically available from numerous suppliers, they are subject to price fluctuations, which could have a negative impact on our results. We seek to minimize the effects of inflation and changing prices through price increases to maintain reasonable gross margins.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
Management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America, and as defined in Exchange Act Rule 13a-15(f).
Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting.
Management has used the framework set forth in the report entitled “Internal Control — Integrated Framework” (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission to assess the effectiveness of the Company’s internal control over financial reporting. Management excluded Iridian Spectral Technologies and STC Material Solutions from its assessment of internal controls over financial reporting as these acquisitions occurred in 2023 (see Note 2 in the Notes to the Consolidated Financial Statements for further detail). This exclusion is in accordance with the general guidance from the Staff of the Securities and Exchange Commission that an assessment of a recently acquired business may be omitted from the scope of management’s assessment of internal control over financial reporting for one year following the acquisition. The total assets (excluding goodwill and intangible assets) and net sales of current year acquisitions represented approximately one percent and zero percent, respectively, of the Consolidated Financial Statement amounts as of and for the year ended December 31, 2023. Based on that assessment, management has concluded that the Company’s internal control over financial reporting was effective as of December 31, 2023.
The effectiveness of the Company’s internal control over financial reporting as of December 31, 2023, has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which appears herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the shareholders and the Board of Directors of IDEX Corporation
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of IDEX Corporation and subsidiaries (the “Company”) as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2023, of the Company and our report dated February 22, 2024, expressed an unqualified opinion on those financial statements.
As described in Management’s Report on Internal Control over Financial Reporting, management excluded Iridian Spectral Technologies and STC Material Solutions from its assessment of internal control over financial reporting as these acquisitions occurred in the twelve months ended December 31, 2023. The combined total assets and net sales of these acquisitions represented approximately one percent and zero percent, respectively, of the consolidated financial statement amounts as of and for the year ended December 31, 2023. Accordingly, our audit did not include the internal control over financial reporting at these acquired companies.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the shareholders and the Board of Directors of IDEX Corporation
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of IDEX Corporation and subsidiaries (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, equity, and cash flows, for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 22, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Revenue — Disaggregation of Revenue — Refer to Note 5 to the financial statements
Critical Audit Matter Description
The Company is a highly diversified business with a wide range of products and services that are offered in various markets throughout the world. The Company’s business activities are carried out by numerous individual business units, which offer a unique set of products and include niche markets within specific geographic areas.
We identified revenue as a critical audit matter given the disaggregated nature of the Company’s operations and business units generating revenue. This required extensive audit effort due to the volume of the underlying transactions and distinctiveness of each individual business unit. High levels of auditor judgment were necessary to determine the nature, timing, and extent of audit procedures and the level of disaggregation within the Company at which to perform such procedures, especially given limited market data for certain products or geographic areas.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the Company’s revenue transactions included the following, among others:
39

Table of Contents
•We tested internal controls within the relevant revenue business processes, including controls over revenue recognition and controls over the review of significant revenue transactions and operating results.
•For a sample of revenue transactions, we performed detail transaction testing by agreeing the amounts recorded to source documents and determined that revenue was recognized appropriately.
•For revenue transactions not subject to detail transaction testing, we aggregated the revenue transactions at the reporting unit level and performed substantive analytical procedures. We developed independent expectations of revenue based on data derived from published industry indices and market and customer trends and compared our independent expectations to the revenue recorded by management.

These products and services are grouped into three reportable segments: Fluid & Metering Technologies (“FMT”), Health & Science Technologies (“HST”) and Fire & Safety/Diversified Products (“FSDP”).
Principles of Consolidation
The Consolidated Financial Statements include the Company and its subsidiaries. All intercompany transactions and accounts have been eliminated.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The principal areas of estimation reflected in the financial statements are revenue recognition, sales returns and allowances, allowance for credit losses, inventory valuation, recoverability of long-lived assets, valuation of goodwill and intangible assets, income taxes, product warranties, contingencies and litigation, insurance-related items, defined benefit retirement plans and purchase accounting related to acquisitions.
Revenue Recognition
The Company accounts for a contract with a customer when it has approval from both parties, the rights and payment terms are identified, the contract has commercial substance and collectability of the consideration is probable. The Company determines the appropriate revenue recognition by analyzing the terms and conditions of the contract. Revenue, or Net sales, is recognized when control of the products or services is transferred to a customer at an amount that reflects the consideration the Company expects to be entitled to in exchange for transferring the products or providing the services. Control is transferred to customers when performance obligations within a contract are satisfied. A performance obligation is a promise to transfer a distinct product or service to a customer.
The majority of the Company's contracts have a single performance obligation which represents, in most cases, the product being sold to the customer. Some contracts include multiple performance obligations such as a product and related installation, extended warranty, software and/or maintenance services. For contracts with multiple performance obligations, the Company allocates the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation.
The Company’s performance obligations are satisfied at either a point in time or over time as work progresses. For performance obligations satisfied at a point in time, revenue is recognized when control transfers to the customer, typically upon shipment. For performance obligations in which the Company transfers control of a product or service over time, revenue is recognized over time as work is performed. Typically, this results when the Company performs services over time or the Company creates a product with no alternative use and has an enforceable right to payment for its performance to date.
46

Table of Contents
For contracts that require complex design, manufacturing and installation activities, certain performance obligations may not be separately identifiable and, therefore, not distinct. As a result, the entire contract is accounted for as a single performance obligation. For contracts that include distinct products or services that are substantially the same and have the same pattern of transfer to the customer over time, they are recognized as a series of distinct products or services. For product sales, each product sold to a customer generally represents a distinct performance obligation. Certain contracts have multiple performance obligations for which the Company allocates the transaction price to each performance obligation using an estimate of the standalone selling price of each distinct product or service and recognizes as revenue when, or as, the performance obligation is satisfied. In such cases, the observable standalone sales are used to determine the standalone selling price. In certain cases, the Company may be required to estimate the standalone selling price using the expected cost plus margin approach, under which it forecasts the expected costs of satisfying a performance obligation and then adds an appropriate margin for the distinct product or service.
When accounting for over-time contracts, the Company uses an input measure to determine the extent of progress towards completion of the performance obligation. The Company believes this measure of progress best depicts the transfer of control to the customer which occurs as the Company incurs costs on its contracts. Incurred cost represents work performed, which corresponds with the transfer of control to the customer. Contract costs include labor, material and overhead. Revenue is recognized based on the relationship between actual costs incurred to date for each contract and the total estimated costs for such contract at completion of the performance obligation. Contract estimates are based on various assumptions to project the outcome of future events. These assumptions include labor productivity and availability; the complexity of the work to be performed; the cost and availability of materials; the performance of subcontractors; and the availability and timing of funding from the customer. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred.
As a significant change in one or more of these estimates could affect the profitability of the Company’s contracts, the Company reviews and updates its estimates regularly. Due to uncertainties inherent in the estimation process, it is reasonably possible that completion costs, including those arising from contract penalty provisions and final contract settlements, will be revised. Such revisions to costs and income are recognized in the period in which the revisions are determined as a cumulative catch-up adjustment. The impact of the adjustment on profit recorded to date on a contract is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance are recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, the Company recognizes provisions for estimated losses on incomplete contracts in the period in which such losses are determined.
The Company records allowances for discounts and product returns at the time of sale as a reduction of revenue as such allowances can be reliably estimated based on historical experience and known trends. The Company also offers product warranties (primarily assurance-type) and accrues its estimated exposure for warranty claims at the time of sale based upon the length of the warranty period, warranty costs incurred and any other related information known to the Company.
Contract Assets and Liabilities
The timing of billings and cash collections can result in customer receivables, billings in excess of revenue recognized, advance payments or deposits. Customer receivables include both amounts billed and currently due from customers as well as unbilled amounts (contract assets) and are included in Receivables - net on the Consolidated Balance Sheets. Amounts are billed in accordance with contractual terms or as work progresses. Unbilled amounts arise when the timing of billing differs from the timing of revenue recognized, such as when contract provisions require specific milestones to be met before a customer can be billed. Unbilled amounts primarily relate to performance obligations satisfied over time when the cost-to-cost method is utilized and the revenue recognized exceeds the amount billed to the customer as there is not yet a right to invoice in accordance with contractual terms. Unbilled amounts are recorded as a contract asset when the revenue associated with the contract is recognized prior to billing and derecognized when billed in accordance with the terms of the contract.
Contract liabilities include advance payments, deposits and billings in excess of revenue recognized and are included in deferred revenue which is classified as current or noncurrent based on the timing of when the Company expects to recognize the revenue. The current portion is included in Accrued expenses and the noncurrent portion is included in Other noncurrent liabilities on the Consolidated Balance Sheets. Advance payments and deposits represent contract liabilities and are recorded when customers remit contractual cash payments in advance of us satisfying performance obligations under contractual arrangements, including those with performance obligations satisfied over time. The Company generally receives advance payments from customers related to maintenance services which are recognized ratably over the service term. The Company also receives deposits from customers on certain orders which the Company recognizes as revenue at a point in time. Billings in excess of revenue recognized represent contract liabilities and primarily relate to performance obligations satisfied over time when the cost-to-cost method is utilized and revenue cannot yet be recognized as the Company has not completed the

corresponding performance obligation. Contract liabilities are derecognized when revenue is recognized and the performance obligation is satisfied.
Shipping and Handling Costs
Shipping and handling costs are included in Cost of sales and are recognized as a period expense during the period in which they are incurred.
Advertising Costs
Advertising costs of $15.9 million, $14.9 million and $10.7 million for 2023, 2022 and 2021, respectively, are expensed as incurred within Selling, general and administrative expenses.
Cash and Cash Equivalents
The Company considers all highly liquid instruments purchased with an original maturity of 3 months or less to be cash and cash equivalents.
Marketable Securities
From time to time, the Company may hold investments in marketable securities, which are recorded in Other current assets in the Consolidated Balance Sheets. These investments are recorded at fair value, with gains and losses, dividends and interest income included in Other expense (income) - net in the Consolidated Statements of Income. See Note 8 for further discussion on the marketable securities held by the Company.
Accounts Receivable and Allowance for Credit Losses
Accounts receivable are recorded at face amount less an allowance for credit losses. The allowance is an estimate based on historical collection experience, current and future economic and market conditions and a review of the current status of each customer's trade accounts receivable. Management evaluates the aging of the accounts receivable balances and the financial condition of its customers and all other forward-looking information that is reasonably available to estimate the amount of accounts receivable that may not be collected in the future and records the appropriate provision.
Inventories
The Company states inventories at the lower of cost or net realizable value. Cost, which includes material, labor and overhead, is determined on a first in, first out basis. The Company makes adjustments to reduce the cost of inventory to its net realizable value, if required, for estimated excess, obsolete, zero usage or impaired balances. Factors influencing these adjustments include changes in market demand, product life cycle and engineering changes.
Impairment of Long-Lived Assets
A long-lived asset is reviewed for impairment if an event occurs or circumstances change that would more likely than not reduce the fair value of the asset below its carrying value, as measured by comparing its net book value to the projected undiscounted future cash flows generated by its use. The Company groups and evaluates these long-lived assets for impairment at the lowest level at which individual cash flows can be identified. A long-lived asset impairment exists when the carrying value of the asset group exceeds its fair value. The amount and timing of the impairment charge for an asset group requires the estimation of future cash flows, which are then discounted to determine the fair value of the asset group. An impaired asset group is recorded at its estimated fair value. Refer to Note 14 for further discussion on impairment of long-lived assets.
Goodwill and Indefinite-Lived Intangible Assets
Accounting Standards Codification (“ASC”) 350, Goodwill and Other Intangible Assets (“ASC 350”), requires that the Company review the carrying value of goodwill and indefinite-lived intangible assets annually, or if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. The Company evaluates the recoverability of these assets as of October 31 based on the estimated fair value of each reporting unit and the indefinite-lived intangible assets. See Note 6 for further discussion on goodwill and indefinite-lived intangible assets.

Borrowing Expenses
Expenses incurred in securing and issuing debt are capitalized and included as a reduction of Long-term borrowings - net. These amounts are amortized over the life of the related borrowing and the related amortization is included in Interest expense in the Consolidated Statements of Income.
Earnings per Common Share
Diluted earnings per common share (“EPS”) attributable to IDEX is computed by dividing Net income attributable to IDEX by the weighted average number of common shares outstanding (basic) plus common stock equivalents outstanding (diluted) during the year. Common stock equivalents consist of restricted stock, performance share units and stock options, which have been included in the calculation of weighted average common shares outstanding using the treasury stock method.
ASC 260, Earnings Per Share, concludes that all outstanding unvested share-based payment awards that contain rights to non-forfeitable dividends participate in undistributed earnings with common shareholders. If awards are considered participating securities, the Company is required to apply the two-class method of computing basic and diluted earnings per share. The Company has determined that its outstanding shares of restricted stock are participating securities. Accordingly, Diluted EPS attributable to IDEX was computed using the two-class method prescribed by ASC 260.
Basic weighted average common shares outstanding reconciles to diluted weighted average common shares outstanding as follows:

| 2023 |  | 2022 |  | 2021
| (In millions)
Basic weighted average common shares outstanding | 75.6 |  |  | 75.7 |  |  | 76.0 |
Dilutive effect of restricted stock, performance share units and stock options | 0.3 |  |  | 0.3 |  |  | 0.4 |
Diluted weighted average common shares outstanding | 75.9 |  |  | 76.0 |  |  | 76.4 |

Options to purchase shares of common stock that were not included in the computation of Diluted EPS attributable to IDEX because the effect of their inclusion would have been antidilutive were as follows:

| 2023 |  | 2022 |  | 2021
Antidilutive shares not included in Diluted EPS attributable to IDEX | 0.2 |  |  | 0.5 |  |  | 0.3 |

Share-Based Compensation
The Company accounts for share-based payments in accordance with ASC 718, Compensation-Stock Compensation. Accordingly, the Company expenses the fair value of the awards granted under its share-based compensation plans. That cost is recognized in the Consolidated Financial Statements over the requisite service period of the grants. See Note 15 for further discussion on share-based compensation.
Depreciation and Amortization
Property and equipment are stated at cost, with depreciation provided using the straight-line method over the following estimated useful lives:

Land improvements | 8 to 12 years
Buildings and improvements | 8 to 30 years
Machinery, equipment and other | 3 to 12 years
Office and transportation equipment | 2 to 10 years

49

Table of Contents
Certain identifiable intangible assets are amortized over their estimated useful lives using the straight-line method. The estimated useful lives used in the computation of amortization of identifiable intangible assets are as follows:

Patents | 5 to 20 years
Trade names | 15 to 20 years
Customer relationships | 5 to 20 years
Unpatented technology | 8 to 20 years
Software | 5 years

Research and Development Expenditures
Costs associated with engineering activities, including research and development, are expensed in the period incurred and are included in Cost of sales.
Total engineering expenses, which include research and development as well as application and support engineering, were $107.5 million, $95.4 million and $82.9 million in 2023, 2022 and 2021, respectively. Research and development expenses, which include costs associated with developing new products and major improvements to existing products, were $68.4 million, $61.4 million and $50.1 million in 2023, 2022 and 2021, respectively.
Foreign Currency Translation and Transaction
The functional currency of substantially all operations outside the United States is the respective local currency. Accordingly, those foreign currency balance sheet accounts have been translated using the exchange rates in effect as of the balance sheet date and the income statement amounts have been translated using the average monthly exchange rates for the year. Translation adjustments from year to year have been reported in Accumulated other comprehensive loss in the Consolidated Balance Sheets. Foreign currency transaction gains and losses from transactions denominated in a currency other than the functional currency of the subsidiary involved are reported within Other expense (income) - net in the Consolidated Statements of Income. Net transaction loss (gain) for the years ended December 31, 2023, 2022 and 2021 was $7.3 million, $(0.8) million and $1.1 million, respectively.
Income Taxes
Income tax expense includes U.S., state, local and international income taxes. Deferred tax assets and liabilities are recognized for the tax consequences of temporary differences between the financial reporting and tax bases of existing assets and liabilities and for loss carryforwards. The tax rate used to determine the deferred tax assets and liabilities is the enacted tax rate for the year and the manner in which the differences are expected to reverse. Valuation allowances are recorded to reduce deferred tax assets to the amount that will more likely than not be realized. See Note 12 for further discussion on income taxes.
Concentration of Credit Risk
The Company is not dependent on a single customer as its largest customer accounted for less than 3% of net sales for all years presented.
Recently Adopted Accounting Standards
In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which adds contract assets and contract liabilities to the list of exceptions to the recognition and measurement principles that apply to business combinations and requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with revenue recognition guidance. The Company adopted this standard on a prospective basis for the annual period beginning January 1, 2023. The adoption of this standard did not have a material impact on the Company’s Consolidated Financial Statements.
Recently Issued Accounting Standards
In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which improves the disclosures required for reportable segments in the Company’s annual and interim financial
50

Table of Contents
statements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Adoption of this ASU should be applied retrospectively to all prior periods presented in the financial statements. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of this standard on the Company’s Consolidated Financial Statements and disclosures.
In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to provide disclosures of specific categories in the rate reconciliation, additional information for reconciling items that meet a quantitative threshold and income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of this standard on the Company’s Consolidated Financial Statements and disclosures.
2. Acquisitions and Divestitures
All of the Company’s acquisitions of businesses have been accounted for under ASC 805, Business Combinations. Accordingly, the assets and liabilities of the acquired companies, after adjustments to reflect the fair values assigned to the assets and liabilities, have been included in the Company’s Consolidated Balance Sheets from their respective dates of acquisition. The results of operations of businesses acquired have been included in the Company’s Consolidated Statements of Income since the respective dates of acquisition. The results of operations of divestitures have been included in the Company’s Consolidated Statements of Income through the respective dates of disposition. Supplemental pro forma information has not been provided as the acquisitions did not have a material impact on the Company’s Consolidated Financial Statements individually or in the aggregate. In addition, the divestitures did not represent a strategic shift that had a major effect on operations and financial results and, therefore, did not qualify for presentation as discontinued operations.
2023 Acquisitions
Iridian
On May 19, 2023, the Company acquired Iridian Spectral Technologies (“Iridian”) in a stock acquisition. Iridian is a global leader in designing and manufacturing thin-film, multi-layer optical filters serving the laser communications, telecommunications and life sciences markets and expands the Company’s array of optical technology offerings. Headquartered in Ottawa, Canada, Iridian operates in the Company’s Scientific Fluidics & Optics reporting unit within the HST segment. Iridian was acquired for cash consideration of $109.8 million. The entire purchase price was funded with cash on hand. Goodwill and intangible assets recognized as part of this transaction were $52.7 million and $45.6 million, respectively.

3. Collaborative Investments
On May 12, 2020, a subsidiary of IDEX entered into a joint venture agreement with a third party to form a limited liability company (the “Joint Venture”) that manufactures and sells high performance elastomer seals for the oil and gas industry to customers within the Kingdom of Saudi Arabia as well as exports these high performance elastomer seals outside of the Kingdom of Saudi Arabia. The Joint Venture maintains operations in Dammam, Saudi Arabia and operates in the Company’s Sealing Solutions reporting unit within the HST segment. The Company has contributed $0.7 million f or 55% of the share capital while the third-party partner has contributed $0.6 million for 45% of the shar e capital. The Joint Venture has been selling since July 2022. Since IDEX controls the entity, IDEX has consolidated the Joint Venture and recorded a Noncontrolling interest in its Consolidated Financial Statements.
During 2021 and 2022, a subsidiary of IDEX funded a total of $7.2 million in promissory notes as an investment in a start-up company that provides communication technology to improve individual performance and team coordination for firefighters’ responses, which aligns with IDEX’s FSDP segment’s strategic plan. On a quarterly basis, the Company evaluates whether an allowance for credit losses is required for these promissory notes and measures the allowance using the current expected credit loss model. During the second quarter of 2023, IDEX determined that its investment may no longer be recoverable. As a result, IDEX recorded a credit loss of $7.7 million in Other expense (income) - net in the Consolidated Statements of Income and a reserve in Other noncurrent assets on the Consolidated Balance Sheets for the full amount of the principal and accrued interest outstanding. During the fourth quarter of 2023, IDEX converted the promissory notes to equity, resulting in a cost method investment with zero value.

Goodwill represents the purchase price in excess of the net amount assigned to the assets acquired and liabilities assumed and was tested for impairment at each of the Company’s reporting units as determined in accordance with ASC 350 as of October 31, 2023, the Company’s annual impairment test date, with no impairment noted. In assessing the fair value of the reporting units, the Company considers both the market approach and the income approach. Under the market approach, the fair value of the reporting unit is determined by the respective trailing 12 month earnings before interest, income taxes, depreciation and amortization (“EBITDA”) and the forward looking 2024 EBITDA (50% each), based on multiples of comparable public companies. The market approach is dependent on a number of significant management assumptions including forecasted EBITDA and selected market multiples. Under the income approach, the fair value of the reporting unit is determined based on the present value of estimated future cash flows. The income approach is dependent on a number of significant management assumptions including estimates of operating results, capital expenditures, net working capital requirements, long-term growth rates and discount rates. Weighting was equally attributed to both the market and the income approaches (50% each) in arriving at the fair value of the reporting units. In 2023 and 2022, there were no events or circumstances that would have required an interim impairment test.

The Banjo and Akron Brass trade names are indefinite-lived intangible assets that were also tested for impairment as of October 31, 2023, with no impairments noted. These indefinite-lived intangible assets are tested for impairment on an annual basis in accordance with ASC 350 or more frequently if events or changes in circumstances indicate that the assets might be impaired. The Company uses the relief-from-royalty method, a form of the income approach, to determine the fair value of these trade names. The relief-from-royalty method is dependent on a number of significant management assumptions, including estimates of revenues, royalty rates and discount rates. In 2023 and 2022, there were no events or circumstances that would have required an interim impairment test.
Amortization of intangible assets was $94.9 million, $69.0 million and $56.4 million in 2023, 2022 and 2021, respectively. Based on the intangible asset balances as of December 31, 2023, expected amortization expense for the years 2024 through 2028 is as follows:

Maturity of Intangible Assets |  | Estimated Amortization
2024 |  | $ | 98.8 |
2025 |  | 97.3 |
2026 |  | 95.7 |

Revolving Credit Facility and Term Facility
On November 1, 2022, the Company entered into an amended and restated credit agreement (as amended and restated, the “Credit Agreement”) along with certain of its subsidiaries, as borrowers (the “Borrowers”), Bank of America, N.A., as administrative agent, swing line lender and an issuer of letters of credit, and other agents party thereto. The Credit Agreement consists of a revolving credit facility in an aggregate principal amount of $800 million and a term credit facility available to the Company in an aggregate principal amount of $200 million, both of which have a final maturity date of November 1, 2027. The maturity date of the Revolving Facility may be extended under certain conditions for an additional one-year term. Up to $100 million of the Revolving Facility is available for the issuance of letters of credit. Additionally, up to $50 million of the Revolving Facility is available to the Company for swing line loans, available on a same-day basis.
Proceeds of the Revolving Facility are available for use by the Borrowers for working capital and other general corporate purposes, including refinancing existing debt of the Company and its subsidiaries and financing of acquisitions. The Company may request increases in the lending commitments under the Credit Agreement, but the aggregate lending commitments pursuant to such increases may not exceed $400 million. The Company has the right, subject to certain conditions set forth in the Credit Agreement, to designate certain foreign subsidiaries of the Company as borrowers under the Credit Agreement. In connection with any such designation, the Company is required to guarantee the obligations of any such subsidiaries under the Credit Agreement. During 2023, the Company repaid $150.0 million of the $200.0 million previously outstanding under the Term Facility.
Borrowings under the Credit Agreement bear interest, at either an alternate base rate or Term SOFR (or appropriate alternative currency reference rates) plus, in each case, an applicable margin. Such applicable margin is based on the better of the Company’s senior, unsecured, long-term debt rating or the Company’s applicable leverage ratio and can range from 0.00% to 1.275%. Interest is payable (a) in the case of base rate loans, quarterly, and (b) in the case of Term SOFR loans, on the last day of the applicable interest period selected, or every three months from the effective date of such interest period for interest periods exceeding three months. The weighted-average interest rate for borrowings outstanding under the Revolving Facility was 4.22% during 2023 and 3.32% during 2022 for the period following the issuance of the Revolving Facility. The weighted-average interest rate for borrowings outstanding under the Term Facility was 6.22% during 2023 and 5.83% during 2022 for the period following the issuance of the Term Facility.
The Credit Agreement requires payment to the lenders of a facility fee based upon the amount of the lenders’ commitments under the credit facility from time to time, equal to the applicable interest rate times the actual daily amount of the Revolving Facility. Voluntary prepayments of any loans and voluntary reductions of the unutilized portion of the commitments under the credit facility are permissible without penalty, subject to break funding payments and minimum notice and minimum reduction amount requirements.

The Credit Agreement gives the Company the option to enter into a future environmental, social and governance amendment by which pricing may be adjusted pursuant to the Company’s performance measured against certain key performance indicators agreed by the Company and BofA Securities, Inc., as sustainability coordinator.
At December 31, 2023, there was $81.0 million outstanding under the Revolving Facility and $3.4 million of outstanding letters of credit, resulting in a net available borrowing capacity under the Revolving Facility of approximately $715.6 million.
Senior Notes
On June 13, 2023, the Company completed a private placement of $100.0 million aggregate principal amount of 5.13% Senior Notes due June 13, 2028 pursuant to a Note Purchase and Master Note Agreement, dated as of June 13, 2023, among the Company, NYL Investors LLC (“New York Life”) and certain affiliates of New York Life identified as Purchasers of the 5.13% Senior Notes therein. The 5.13% Senior Notes are unsecured obligations of the Company and rank pari passu in right of payment with all of the Company’s other unsecured, unsubordinated debt. The Company used the proceeds from the 5.13% Senior Notes issuance to repay the 3.20% Senior Notes due June 13, 2023.
Inclusive of the 5.13% Senior Notes, at December 31, 2023, the Company has $1.2 billion in senior notes outstanding at various interest rates detailed in the table above (the “Senior Notes”). Interest on the Senior Notes is payable semi-annually in arrears during the second and fourth quarters of the year. The Senior Notes are unsecured obligations of the Company and rank pari passu in right of payment with all of the Company’s other unsecured, unsubordinated debt. Subject to the terms of the respective indenture, the Company may redeem all or a portion of the Senior Notes at any time prior to maturity at the redemption prices set forth in the indenture. The terms of the 2.625% Senior Notes and the 3.00% Senior Notes also require the Company to make an offer to repurchase the 2.625% Senior Notes and the 3.00% Senior Notes upon a change of control triggering event (as defined in the indenture) at a price equal to 101% of the principal amount plus accrued and unpaid interest, if any. The terms of the 3.37% Senior Notes and the 5.13% Senior Notes also require the Company to make an offer to repurchase the 3.37% Senior Notes and the 5.13% Senior Notes upon a change of control (as defined in the note purchase agreement) of the Company at a price equal to 100% of the principal amount plus accrued and unpaid interest, if any.
Covenants
There are two key financial covenants that the Company is required to maintain in connection with the Credit Agreement and the Senior Notes, excluding the 3.00% Senior Notes and the 2.625% Senior Notes which have no financial covenants. Those two covenants include a minimum interest coverage ratio of 3.0 to 1 and a maximum leverage ratio of 3.50 to 1, which is the ratio of the Company’s consolidated total debt to its consolidated EBITDA, both of which are tested quarterly and in the case of the leverage ratio, there is an option to increase the ratio to 4.00 for 12 months in connection with certain acquisitions. While there are no financial covenants relating to the 3.00% Senior Notes and the 2.625% Senior Notes, they are subject to cross-default provisions. At December 31, 2023, the Company was in compliance with all covenants under our borrowing arrangements.
Total borrowings at December 31, 2023 have scheduled maturities as follows:

8. Fair Value Measurements
ASC 820, Fair Value Measurements and Disclosures, defines fair value, provides guidance for measuring fair value and requires certain disclosures. This standard discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost). The standard utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:
•Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.
•Level 2: Inputs, other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.
•Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions.
The following table summarizes the basis used to measure the Company’s financial assets (liabilities) at fair value on a recurring basis in the balance sheets at December 31, 2023 and 2022:

| Basis of Fair Value Measurements
| December 31, 2023 |  | December 31, 2022
| Level 1 |  | Level 1
Trading securities - mutual funds held in nonqualified SERP(1) | $ | 10.5 |  |  | $ | 7.5 |
Available-for-sale securities - equities(2) | 4.4 |  |  | — |

(1) The Supplemental Executive Retirement Plan (“SERP”) investment assets are offset by a SERP liability which represents the Company’s obligation to distribute SERP funds to participants.
(2) At December 31, 2023, t he securities are included in Other current assets on the Company’s Consolidated Balance Sheets and are available for overnight cash settlement, if necessary, to fund current operations.
There were no transfers of assets or liabilities between Level 1 and Level 2 in 2023 or 2022.
The carrying values of the Company’s cash and cash equivalents, accounts receivable, marketable securities, accounts payable and accrued expenses approximate fair value because of the short term nature of these instruments.
The following table provides the fair value of the outstanding indebtedness described in Note 7, which is based on quoted market prices and current market rates for debt with similar credit risk and maturity, as well as the carrying value. These fair value measurements are classified as Level 2 within the fair value hierarchy since they are determined based upon significant inputs observable in the market, including interest rates on recent financing transactions to entities with a credit rating similar to the Company’s rating.

| December 31, 2023 |  | December 31, 2022
| Fair Value |  | Carrying Amount |  | Fair Value |  | Carrying Amount
Total Borrowings, less unaccreted debt discount | $ | 1,203.5 |  |  | $ | 1,332.2 |  |  | $ | 1,328.7 |  |  | $ | 1,476.6 |

9. Leases
The Company has commitments under operating leases for certain office facilities, warehouses, manufacturing plants, equipment (which includes both office and plant equipment) and vehicles used in its operations. Leases with an initial term of 12 months or less are not recorded on the balance sheet and the Company recognizes lease expense for these leases on a straight-line basis over the lease term.
Certain leases include one or more options to renew. The exercise of lease renewal options is at the Company’s sole discretion. The Company does not include renewal periods in any of the leases’ terms until the renewal is executed as they are generally not reasonably certain of being exercised. The Company does not have any material purchase options.

The Company has $54.9 million and $45.3 million of permanently reinvested earnings of non-U.S. subsidiaries as of December 31, 2023 and 2022, respectively. No deferred U.S. income taxes have been provided on the $54.9 million of earnings that are considered to be permanently reinvested. The Company does not expect these earnings to incur U.S. taxes when ultimately repatriated other than potentially U.S. federal, state and local taxes on foreign exchange gains or losses recognized on the distribution of such earnings. Such distributions could also be subject to additional foreign withholding and foreign income taxes. The amount of unrecognized deferred income tax liabilities on currently permanently reinvested earnings is estimated to be $8.2 million and $6.8 million as of December 31, 2023 and 2022, respectively.
During the years ended December 31, 2023, 2022 and 2021, the Company repatriated $134.1 million, $199.9 million and $116.0 million of foreign earnings, respectively. These actual distributions resulted in no incremental income tax expense other than tax impacts on foreign exchange gains or losses. These repatriations represent distributions of previously taxed income.
A reconciliation of the beginning and ending amount of unrecognized tax benefits for 2023, 2022 and 2021 is as follows:

| 2023 |  | 2022 |  | 2021
Beginning balance January 1 | $ | — |  |  | $ | 0.1 |  |  | $ | 1.1 |
Gross increases for tax positions of prior years | — |  |  | — |  |  | 0.1 |
Gross decreases for tax positions of prior years | — |  |  | — |  |  | (0.3) |
Settlements | — |  |  | — |  |  | (0.2) |
Lapse of statute of limitations | — |  |  | (0.1) |  |  | (0.6) |
Ending balance December 31 | $ | — |  |  | $ | — |  |  | $ | 0.1 |

As of December 31, 2023, the Company has no remaining unrecognized tax benefits that would affect the Company’s effective tax rate. The tax years 2018-2022 remain open to examination by major taxing jurisdictions. Due to the potential federal, state and foreign examinations, it is reasonably possible that the Company’s gross unrecognized tax benefits balance may change.

14. Restructuring Expenses and Asset Impairments
From time to time, the Company incurs expenses to facilitate long-term sustainable growth through cost reduction actions, consisting of employee reductions, facility rationalization and contract termination costs. These costs include severance costs, exit costs and asset impairments and are included in Restructuring expenses and asset impairments in the Consolidated Statements of Income. Severance costs primarily consist of severance benefits through payroll continuation, COBRA subsidies, outplacement services, conditional separation costs and employer tax liabilities, while exit costs primarily consist of lease exit and contract termination costs.
2023 Initiative
During the year ended December 31, 2023, the Company incurred severance costs related to employee reductions in conjunction with cost mitigation efforts as a result of current market conditions, contract termination costs and asset impairments.
Pre-tax Restructuring expenses and asset impairments by segment for the 2023 initiative were as follows:

| Severance Costs |  | Exit Costs |  | Asset Impairments |  | Total
Fluid & Metering Technologies | $ | 1.5 |  |  | $ | 0.6 |  |  | $ | 0.8 |  |  | $ | 2.9 |
Health & Science Technologies | 6.4 |  |  | 0.2 |  |  | — |  |  | 6.6 |

Total restructuring costs | $ | 9.1 |  |  | $ | 1.0 |  |  | $ | 0.8 |  |  | $ | 10.9 |

2022 Initiative
During the year ended December 31, 2022, the restructuring costs incurred by the Company primarily related to asset impairments. In addition, the Company also incurred severance costs related to employee reductions.
In the second quarter of 2020, the Company engaged in the development of a COVID-19 testing application with a customer at one of the Company’s businesses in the HST segment. As part of this contract, the customer fully funded the $28.7 million investment needed to complete the development and production of microfluidic cartridges during 2020 and 2021. The costs incurred by the Company were primarily recorded as Property, plant and equipment – net in the Consolidated Balance Sheets and were being depreciated over the expected life of the assets, while the reimbursement was recorded as Deferred revenue in the Consolidated Balance Sheets and was being recognized as units were shipped.
In the third quarter of 2022, the Company was informed by the customer of its decision to discontinue further investment in commercializing its COVID-19 testing application. This event was deemed a triggering event, which required an interim impairment test be performed on the property, plant and equipment related to this contract, resulting in an impairment charge of $16.8 million that was recorded as Restructuring expenses and asset impairments in the Consolidated Statements of Income during the year ended December 31, 2022. In addition, the Company accelerated previously deferred revenue of $17.9 million related to units that are no longer expected to be shipped and recorded it as Net sales in the Consolidated Statements of Income during the year ended December 31, 2022.
Pre-tax Restructuring expenses and asset impairments by segment for the 2022 initiative were as follows:

| Severance Costs |  | Exit Costs |  | Asset Impairments |  | Total
Fluid & Metering Technologies | $ | 1.9 |  |  | $ | 0.3 |  |  | $ | 0.5 |  |  | $ | 2.7 |

2021 Initiative
During the year ended December 31, 2021, the Company incurred severance costs related to employee reductions. In addition, the Company consolidated certain facilities within the FMT segment which resulted in asset impairments of $0.8 million related to property, plant and equipment that was not relocated to the new locations.
Pre-tax restructuring expenses and asset impairments by segment for the 2021 initiative were as follows:

| Severance Costs |  | Exit Costs |  | Asset Impairments |  | Total

15. Share-Based Compensation
The Company maintains two share-based compensation plans for executives, non-employee directors and certain key employees that authorize the granting of restricted stock, performance share units and stock options and other types of awards consistent with the purpose of the plans. The number of shares authorized for issuance under the Company’s plans as of December 31, 2023 totaled 15.6 million, of which 1.7 million shares were available for future issuance.
The Company typically grants equity awards annually at its regularly scheduled first quarter meeting of the Board of Directors based on the recommendation from the Compensation Committee.
The Company’s policy is to recognize compensation cost on a straight-line basis, assuming forfeitures, over the requisite service period for the entire award. Classification of stock compensation cost within the Consolidated Statements of Income is consistent with the classification of cash compensation for the same employees.
Stock Options
Stock options granted under the Company’s plans are generally non-qualified and are granted with an exercise price equal to the market price of the Company’s stock on the date of grant. The fair value of each option grant was estimated on the date of the grant using the Binomial lattice option pricing model (for options granted before March 2021) or the Black Scholes valuation model (for options granted after February 2021). The adoption of the Black Scholes model in 2021 was driven by a review of option exercise history, which more closely aligned with the methodology of the Black Scholes model. Stock options generally vest ratably over four years, with vesting beginning one year from the date of grant, and generally expire 10 years

from the date of grant. The service period for certain retiree eligible participants is accelerated. Weighted average stock option fair values and assumptions for the years ended December 31, 2023, 2022, and 2021 are disclosed below:

| Years Ended December 31,
| 2023 |  | 2022 |  | 2021
Weighted average fair value of grants | $59.77 |  | $42.66 |  | $38.88
Dividend yield | 1.09% |  | 1.14% |  | 1.01%
Volatility | 27.14% |  | 25.23% |  | 23.78%
Risk-free interest rate | 4.15% |  | 2.01% |  | 0.12% - 1.54%
Expected life (in years) | 4.50 |  | 4.90 |  | 5.70

The assumptions are as follows:
•The Company estimated volatility using its historical share price performance over the contractual term of the option (for the Binomial lattice option pricing model) or over the expected life of the option (for the Black Scholes valuation model).
•The Company uses historical data to estimate the expected life of the option. The expected life assumption for options granted before March 2021 is an output of the Binomial lattice option pricing model, which incorporates vesting provisions, rate of voluntary exercise and rate of post-vesting termination over the contractual life of the option to define expected employee behavior. The expected life assumption for options granted after March 2021 is based on IDEX’s own exercise and cancellation history, adjusted for current vesting schedules.
•The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods within the contractual life of the option (for the Binomial lattice option pricing model) or commensurate with the expected life of the option (for the Black Scholes valuation model). For options granted before March 2021, the Company presents the range of risk-free one-year forward rates, derived from the U.S. treasury yield curve, utilized in the Binomial lattice option pricing model. For options granted after March 2021, the Company presents the spot rate used in the Black Scholes valuation model.
•The expected dividend yield is based on the Company’s current dividend yield as the best estimate of projected dividend yield for periods within the contractual life of the option.

Performance Share Units
Beginning in 2013, the Company granted performance share units to selected key employees that may be earned based on IDEX total shareholder return over the three-year period following the date of grant. Performance share units are expected to be made annually and are paid out at the end of a three-year period based on the Company’s performance. Performance is measured by determining the percentile rank of the total shareholder return of IDEX common stock in relation to the total shareholder return of companies in the S&P 500 Index for the three-year period following the date of grant. The payment of awards following the three-year award period will be based on performance achieved in accordance with the scale set forth in the plan agreement and may range from 0 percent to 250 percent of the initial grant. A target payout of 100 percent is earned if total shareholder return is equal to the 50 th percentile of the peer group. Performance share units earn dividend equivalents for the award period, which will be paid to participants with the award payout at the end of the period based on the actual number of performance share units that are earned. Payments made at the end of the award period will be in the form of stock for performance share units and will be in cash for dividend equivalents. The performance share units are market condition awards, have been assessed at fair value on the date of grant using a Monte Carlo simulation model and are expensed ratably over the three-year term of the awards.
Weighted average performance share unit fair values and assumptions for the years ended December 31, 2023, 2022, and 2021 are disclosed below:

| Years Ended December 31,
| 2023 |  | 2022 |  | 2021
Weighted average fair value of grants | $308.18 |  | $235.54 |  | $247.49
Dividend yield | —% |  | —% |  | —%
Volatility | 27.00% |  | 28.09% |  | 28.60%
Risk-free interest rate | 4.37% |  | 1.73% |  | 0.33%
Expected life (in years) | 2.94 |  | 2.93 |  | 2.93

The assumptions are as follows:
•The Company estimated volatility using its historical share price performance over the remaining performance period as of the grant date.
•The Company uses a Monte Carlo simulation model that uses an expected life commensurate with the performance period. As a result, the expected life of the performance share units was assumed to be the period from the grant date to the end of the performance period.
•The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant with a term commensurate with the remaining performance period.
•Total Shareholder Return is determined assuming that dividends are reinvested in the issuing entity over the performance period, which is mathematically equivalent to utilizing a 0% dividend yield.
A summary of the Company’s performance share unit activity as of December 31, 2023, and changes during the year ended December 31, 2023, are presented in the following table:

Performance Share Units | Shares |  | Weighted-Average Grant Date Fair Value

17. Retirement Benefits
The Company sponsors several qualified and nonqualified defined benefit and defined contribution pension plans as well as other post-retirement plans for its employees. The Company uses a measurement date of December 31 for its defined benefit pension plans and post-retirement medical plans. The Company employs the measurement date provisions of ASC 715, Compensation-Retirement Benefits, which require the measurement date of plan assets and liabilities to coincide with the sponsor’s year end.
During the year ended December 31, 2021, the Company settled its remaining obligations under the IDEX Corporation Retirement Plan (“Plan”), a U.S. defined benefit plan which was terminated in May 2020, through a combination of lump-sum payments to eligible participants who elected them, and through the purchase of annuities from Legal and General, an A rated third-party insurer. The Company recognized a net loss of $9.7 million, which was recorded within Other expense (income) - net. The net loss consisted of $10.7 million related to previously deferred pension related costs, partially offset by $1.0 million related to an increase in plan assets remaining after the settlement.

The pension benefits actuarial loss in 2023 was primarily driven by the decrease in the discount rates from 2022 to 2023. The increase in the Eurozone inflation rate contributed further to the reported Non-U.S. pension actuarial loss.
The other benefits actuarial loss in 2023 was primarily driven by the decrease in the discount rates from 2022 to 2023 with additional losses from the updated medical trend assumptions for the U.S. plans, partially offset by gains from updated participants data.
The accumulated benefit obligation for all defined benefit pension plans was $94.6 million and $81.9 million at December 31, 2023 and 2022, respectively.

The discount rates for the Company’s plans are derived by matching the plan’s cash flows to a yield curve that provides the equivalent yields on zero-coupon bonds for each maturity. The discount rate selected is the rate that produces the same present value of cash flows.
In selecting the expected rate of return on plan assets, the Company considers the historical returns and expected returns on plan assets. The expected returns are evaluated using asset return class, variance and correlation assumptions based on the plan’s target asset allocation and current market conditions.
Prior service costs are amortized on a straight-line basis over the average remaining service period of active participants. Gains and losses in excess of 10% of the greater of the benefit obligation or the market value of assets are amortized over the average remaining service period of active participants.
Costs of defined contribution plans were $16.8 million, $16.1 million and $12.8 million for 2023, 2022 and 2021, respectively.
The Company, through its subsidiaries, participates in a multi-employer pension plan covering approximately 211 participants under U.S. collective bargaining agreements. None of these plans are considered individually significant to the Company as contributions to these plans totaled $0.9 million, $0.8 million, and $1.0 million for 2023, 2022 and 2021, respectively.
For measurement purposes, a 6.23% weighted average annual rate of increase in the per capita cost of covered health care benefits was assumed for 2023. The rate was assumed to decrease gradually each year to a rate of 4.00% for 2040, and remain at that level thereafter.

(1)Other commingled funds represent pooled institutional investments in non-U.S. plans.
Equities that are valued using quoted prices are valued at the published market prices. Equities in a common collective trust or a registered investment company that are valued using significant other observable inputs are valued at the net asset value (“NAV”) provided by the fund administrator. The NAV is based on the value of the underlying assets owned by the fund minus its liabilities. Fixed income securities that are valued using significant other observable inputs are valued at prices obtained from independent financial service industry-recognized vendors.
Investment Policies and Strategies
The investment objective of the U.S. plan, consistent with prudent standards for preservation of capital and maintenance of liquidity, is to earn the highest possible total rate of return consistent with the plan’s tolerance for risk. The general asset allocation guidelines for plan assets are that “equities” will constitute 10% and “fixed income” obligations, including cash, will constitute 90% of the market value of total fund assets.
The investment objective of the UK plan, consistent with prudent standards for preservation of capital and maintenance of liquidity, is to earn a target return of UK Gilts plus approximately 2.6% per year. The general asset allocation guidelines for plan assets are that “equities” will constitute from 35% to 45% of the market value of total fund assets with a target of 40%, and “fixed income” obligations, including cash, will constitute from 55% to 65% with a target of 60%. The UK plan also has a framework in place such that if the funding position (which is monitored daily) improves to a certain level, the asset allocation will switch out of equities into fixed income assets in order to lower the level of risk of the investments.
The term “equities” includes common stock, while the term “fixed income” includes obligations with contractual payments and a specific maturity date. Diversification of assets is employed to ensure that adverse performance of one security or security class does not have an undue detrimental impact on the portfolio as a whole. Diversification is interpreted to include diversification by type, characteristic and number of investments as well as by investment style of designated investment fund managers. No restrictions are placed on the selection of individual investments by the investment fund managers. The total fund performance and the performance of the investment fund managers is reviewed on a regular basis using an appointed professional independent advisor. As of December 31, 2023, there were no shares of the Company’s stock held in plan assets.
Cash Flows
The Company expects to contribute approximately $3.6 million to its defined benefit plans and $1.1 million to its other postretirement benefit plans in 2024. The Company also expects to contribute approximately $17.3 million to its defined contribution plan and $13.5 million to its 401(k) savings plan in 2024 using cash on hand.
