CORPORATE GOVERNANCE

Framework for Corporate Governance

The Board of Directors has the ultimate authority for the management of the Company’s business. The Corporate Governance Guidelines, the charters of theBoard committees, the Code of Business Conduct and Ethics, and the Standards for Director Independence (Governance Documents) provide the framework for the governance of the Company. Copies of the current Governance Documents are available under theInvestors link on the Company’s website at www.idexcorp.com.

Corporate Governance Guidelines and Code

of Business Conduct and Ethics

The CorporateGovernance Guidelines address matters such as election of directors, size and retirement age for the Board, Board composition and membership criteria, the role and responsibilities of the Board and each of its committees, Board evaluations and thefrequency of Board meetings (including meetings to be held without the presence of management).

The Code of Business Conduct and Ethics sets forth theguiding principles of business ethics and certain legal requirements applicable to all of the Company’s employees and directors.

Director Independence

The Board has adopted standards for determining whether a director is independent. These standards are based upon thelisting standards of the New York Stock Exchange (NYSE) and applicable laws and regulations and are available on the Company’s website as described above. The Board also reviewed commercial relationships between the Company and organizationswith which directors were affiliated by service as an executive officer. The relationships with these organizations involved the Company’s sale or purchase of products or services in the ordinary course of business that were made on arm’s-length terms and other

circumstances that did not affect the relevant directors’ independence under applicable law and NYSE listing standards.

The Board has affirmatively determined, based on these standards and after considering the relationships described immediately above, that the followingdirectors are independent: Messrs.Beck, Buthman, Christenson, Cook, Mrozek, Parry and Satterthwaite, and Mss. Helmkamp and Warner. The Board has also determined that Mr.Silvernail is not independent because he is the Chief ExecutiveOfficer of the Company (and was, until February21, 2020, President of the Company). All standing Board committees are, and throughout fiscal year 2019 were, composed entirely of independent directors.

Director Nominations

TheBoard believes that maintaining a diverse membership with varying backgrounds, skills, expertise and other differentiating personal characteristics promotes inclusiveness, enhances the Board’s deliberations and enables the Board to betterrepresent all of the Company’s constituents. Accordingly, the Board is committed to seeking out highly qualified women and minority candidates as well as candidates with diverse backgrounds, skills and experiences as part of each Board searchthe Company conducts. The Board considers the following in selecting nominees for the Board:

Experience (in one or more of the following):

•high level leadership experience in business or administrative activities;
•specialized expertise in the industries in which the Company competes;
•financial expertise;
•breadth of knowledge about issues affecting the Company;
•ability and willingness to contribute special competencies to Board activities; and

14

Director generally presides at these non-management executive sessions.During 2019, the Board held seven meetings.

The Board believes that its current leadership structure provides independent board leadership and engagementwhile deriving the benefit of having the Chief Executive Officer also serve as Chairman of the Board.

The Chief Executive Officer, as the individual withprimary responsibility for managing the Company’s day-to-day operations, is best positioned to chair regular Board meetings and to oversee discussion on businessand strategic issues. Coupled with the existence of a Lead Director and regular executive sessions of the non-management directors, this structure provides independent oversight, including risk oversight,while facilitating the exercise of the Board’s responsibilities.

During 2019, each director attended more than 75% of the aggregate number ofmeetings of the Board and of committees of the Board of which he or she was a member. The Company encourages its directors to attend the annual meeting of stockholders but has no formal policy with respect to that attendance. All of the currentdirectors attended the 2019 Annual Meeting of Stockholders.

Board’s Role in Risk Oversight

The Board oversees an annual assessment of enterprise risk exposure, and the management of such risk, conducted by the Company’s executives.

When assessing enterprise risk, the Board focuses on the achievement of organizational objectives, including strategic objectives, to improve long-termperformance and enhance stockholder value. Direct oversight allows the Board to assess management’s inclination for risk, to determine what constitutes an appropriate level of risk for the Company and to discuss with management the means bywhich to control risk.

Board and Committee Assessment Process

On an annual basis, the Board and each Committee conduct assessments, which consist of written self-assessment questionnaires, supplemented by individualinterviews of each director conducted by the Chair of the Nominating and Corporate Governance Committee. The results of the assessment process are then reviewed and discussed by the Board and each Committee and have led to process and oversightimprovements.

Board’s Engagement with Management

The Board approves the Company’s executive officers, delegates responsibilities for the conduct of the Company’s operations to those officers andmonitors their performance. In addition, members of the Board informally mentor executive officers, meeting with such officers individually to share insights and experiences accumulated over the course of the directors’ careers.

Each year, some directors visit Company manufacturing facilities and meet with their leaders. During 2019, directors visited sites in the United States,Europe and China. Some directors attend the Company’s annual global leadership conference of about 150 leaders each year. In addition, each year the Board holds at least one meeting at a Company manufacturing facility where all directors attenda daily management meeting, receive a tour of the facility and participate in an operational review with senior leadership.

Board’s Role in Talent Development and Strategic Planning

Our Board calendar includes at least one meeting per year at which the Boardparticipates in an extensive review of the Company’s talent management and retention strategies, leadership development pipeline and succession plans for senior management.

Each fall the Board participates in a multi-day three-year enterprise strategy review with the

16

Company’s executive officers and other senior management. Management and the Board agree

upon astrategy and it is used as a lens for decision making at each Board meeting following the annual comprehensive review. As a result, strategy discussions are a regular feature of Board meetings throughout the year.

Director Onboarding and Education

All new directors participate in our director onboarding program. The onboarding process includes in-person meetingsat the Company’s headquarters with senior leaders to familiarize new directors with the Company’s strategic vision, values and culture; operational and financial reporting structure; and legal, compliance and governance framework. Inaddition, new directors have also attended training courses led by IDEX senior leaders covering the 80/20 business process that serves as the foundation of IDEX’s operating model and seeks to accelerate profitable growth by focusing resourceson our highest value opportunities.

The Board encourages all directors to participate in continuing director education programs, either individually ortogether with other Committee members, and directors are reimbursed for their expenses for such programs. Over the past year, directors attended off-site education seminars covering a variety of topics,including board and audit committee leadership, strategy, cybersecurity, shareholder activism and regulatory developments. In addition, last spring all directors participated in an educational session led by an outside expert on responsible supplychain practices, which was delivered as part of a regularly-scheduled Board meeting.

Investor Outreach

We value the input of our stockholders and believe that it is important to understand their questions and concerns about the Company. During 2019, we met witha number of our stockholders and prospective stockholders to

answer questions about the Company and learn about matters that are important to them. We plan to continue our investor outreach efforts during 2020.

Corporate Social Responsibility/Non-Financial Highlights

As an embodiment of our commitment to focus on what matters to our various stakeholders, in March 2019, we published our first Corporate Social ResponsibilityReport, which is available under the Corporate Social Responsibility link on our website at www.idexcorp.com. We continued to make great progress in 2019 as a Company in building a culture and environment where all of our employees are engaged andhave the tools and support they need in order to truly do and be their best every day.

Employee Engagement: We have best-in-class employee engagement. In 2019, we were in the top quartile of manufacturing companies in all three indices (employee engagement, manager effectiveness and performance enablement) of our employeeengagement survey, with a response rate of 88% to the survey. In 2018, we were in the top quartile on employee engagement and manager effectiveness.

Community Involvement: We are proud of the efforts of our employees during 2019 to positively impact the communities in which we live and work. The IDEXFoundation provides all business units globally a way to give back to the communities in which we live. From partnering with local food banks and soup kitchens, to helping to build or improve schools, to providing toys, clothing and other essentialsto impoverished or sick children, to donating and assembling toiletry kits for the homeless, IDEX employees around the world are solving problems and improving the lives of the people around them. In partnership with the IDEX Foundation, in 2019more than 2,594 IDEX employees participated in over 66 community or charitable events, spanning three continents and touching thousands of lives.

COMPENSATION OF DIRECTORS

The objectives of our director compensation program are to attract highly-qualified individuals to serve on our Board and to align our directors’interests with the interests of our stockholders. The Compensation Committee periodically reviews the program to ensure that it continues to meet these objectives.

The Company believes that to attract and retain qualified directors, pay levels should be targeted at the 50th percentile (or median) of pay levels fordirectors at comparable companies. On at least a biennial basis, the Compensation Committee, with the assistance of F.W. Cook, evaluates the competitiveness of director compensation. The primary reference point for the determination of market pay isthe peer group of companies. The peer group used in this analysis was the same peer group used for the Company’s executive compensation analysis.

For further details on this topic, refer to “Peer Companies” under “Setting Executive Compensation” in the Compensation Discussion andAnalysis below. Market composite data derived from pay surveys available to F.W. Cook and to the Company is also used.

Our director compensation for 2019and 2020 is set forth below. The changes for 2020 are detailed in the Company’s Amended and Restated Non-Employee Director Compensation Policy (Director Compensation Policy) and reflect market-basedadjustments as a result of the analysis described above.

Table of Contents

Since the start of 2015, directors have had the ability to defer payment of all or a portion of their annualequity grant.

Directors Deferred Compensation Plan

Under the Company’s Directors Deferred Compensation Plan, directors are permitted to defer their cash compensation as of the date their compensationwould otherwise be payable. In general, directors must make elections to defer fees payable during a calendar year by the end of the preceding calendar year. Newly appointed directors have up to 30 days from their appointment to elect to deferfuture fees.

All amounts deferred are recorded in a memorandum account for each director and are credited or debited with earnings or losses as if suchamounts had been invested in an interest- bearing account or certain mutual funds, at the option of the director. The deferred compensation credited to the interest-bearing account is adjusted on at least a quarterly basis with hypothetical earningsequal to the lesser of the Barclays Capital Long Term Bond AAA — Corporate Bond Index as of the first business day in November of the calendar year preceding the year for which the earnings are to be credited or 120% of the long-term applicablefederal rate as of the first business day in November.

In accordance with SEC rules, no earnings on deferred compensation are shown in the DirectorCompensation table below because no “above market” rates were earned on deferred amounts in 2019. Directors must elect irrevocably to

receive the deferred funds either in a lump sum or in equal annual installments of up to 10 years, and to begin receiving distributions either at termination of Board service or at a futurespecified date.

If a director should die before all amounts credited under the Directors Deferred Compensation Plan have been paid, the unpaid balance inthe participating director’s account will be paid to the director’s beneficiary. The memorandum accounts are not funded, and the right to receive future payments of amounts recorded in these accounts is an unsecured claim against theCompany’s general assets.

Stock Ownership Guideline

Under the Director Compensation Policy, non-management directors are subject to a stock ownership guideline. Non-management directors are required to maintain direct ownership of shares of Common Stock equal to or greater in value to five times the current annual Board service retainer. Nonon-management director is permitted to sell shares of Common Stock until the director satisfies the stock ownership guideline, and after a director meets the stock ownership guideline, the director may notsell shares if the sale would put the director below the stock ownership guideline.

As of March13, 2020, allnon-management directors were in compliance with the stock ownership guideline or subject to the mandatory holding requirement until the ownership guideline is met.

Principles of Our CompensationPrograms

Pay-for-Performance

The key principle of our compensation philosophy is
pay-for-performance.

Alignment with Stockholders’
Interests

We reward performance that meets or exceeds the performance
goals that the Compensation Committee establishes with the
objective of increasingstockholder value.

Variation Based on

Performance

We favor variable pay opportunities that are based on
performance over fixed pay. The total compensation received by
our NEOs varies based on corporateand individual performance
measured against annual and long-term goals.

Compensation Philosophy

Thefollowing table describes our compensation philosophy that guides our pay programs, structure and decisions.

CompensationPhilosophy

How WeDeliver

Attract and retain an effective management team

•  We offer a total pay package that consists of both compensation and benefitsthat are targeted to be competitive with the market.

•  We seek to retainour executives by regularly benchmarking our total compensation package relative to companies of similar size, scope and complexity — our peer group is constructed to include companies within an appropriate range of revenue and marketcapitalization values.

Table of Contents

CompensationPhilosophy

How WeDeliver

Motivate and reward management team with a focus onpay-for-performance

•  We tie a meaningful portion of total compensation to financial and stockprice performance – between 70% to 80% of our compensation mix is tied to performance.

•  Our compensation program provides a mix of base salary, short-term incentivesand long-term incentives — the balance of our compensation elements provides direct line of sight with our objectives, motivating executives to outperform on our goals.

•  In line with our compensation philosophy to align pay and performance, when the Companyoutperforms or underperforms the goals in our incentive plans, payouts can result in above or below target levels, respectively.

Create a strong financial incentive that aligns with our stockholders and long-term objectives

•  Through a combination of appropriate performance metrics and targets,executives are paid according to how the Company performs.

•  Specificfinancial measures used in our incentive programs include:

–  Earnings pershare (EPS), cash flow conversion, and organic sales growth in our short-term incentive plan; and

–  Total stockholder return (TSR) relative to companies in the relevant marketindex used in our long-term incentive plan.

Align the interests of management and stockholders

•  In order to emphasize long-term stockholder returns, we require ourexecutives to maintain significant stock ownership levels through the use of stock ownership guidelines.

Governance Best Practices

The Company employs compensation principles in delivering executive pay that we believe are supportive of the business strategy and governance best practices.

What We Do

Ö

AnnualSay-on-Pay Vote: We conduct an annual say-on-pay advisory vote. At our 2019Annual Meeting of Stockholders, more than 96% of the votes cast on the say-on-pay proposal were in favor of the fiscal year 2018 compensation of our NEOs.

Ö

Clawback Policy: Our clawback policy allows the Board to recoup any excessincentive compensation paid to our executive officers and other employees if the financial results on which the awards were based are materially restated due to fraud, intentional misconduct or gross negligence of the executive officer or otheremployee.

Ö

Short-Term and Long-Term Incentives/Measures: Our annual and long-termplans provide a balance of incentives and include different measures of performance.

29

Table of Contents
Ö

Independent Compensation Consultant: The Compensation Committee engages anindependent compensation consultant, who does not provide any services to management.

Ö

Stock Ownership Guidelines: To further align the interests of managementand our directors with our stockholders, we have significant stock ownership guidelines, which require our executive officers and directors to hold a multiple of their annual compensation in Common Stock.

Ö

Limited Perquisites and Related TaxGross-Ups: We provide limited perquisites and tax gross-ups.

Ö

Mitigate Inappropriate Risk Taking: In addition to our clawback policy,stock ownership guidelines and prohibition of hedging and pledging, we structure our compensation programs so that they minimize inappropriate risk taking by our executive officers and other employees, including using multiple performance metricsand multi-year performance periods and capping our annual incentive awards and performance share awards.

What WeDon’t Do

×

Gross-ups for Excise Taxes: Ourexecutive severance agreements do not contain a gross-up for excise taxes that may be imposed as a result of severance or other payments deemed made in connection with a change in control.

×

Reprice Stock Options: Our equity incentive plan prohibits the repricing ofstock options and stock appreciation rights without prior stockholder approval.

×

Fixed Term Employment Agreements: Employment of our executive officers(other than our CEO) is “at will” and may be terminated by either the Company or the employee at any time.

×

Hedging and Pledging: Our insider trading policy prohibits all employeesand directors from hedging and pledging their economic interest in the Common Stock they hold.

Key Takeaways of our 2019 Executive Compensation Program

For 2019, our executive compensation programs were designed to directly link compensation opportunities to the financial performance metrics that we believeare the best measures of success in our business: EPS, cash flow conversion, organic sales growth and relative TSR.

•

The 2019 bonus payouts were 87% of target.

•

Our TSR for the 2017-2019 period was 88%, which resulted in an82nd percentile performance compared to the companies in the Russell Midcap Index and resulted in a 250% payout of performance stock units (PSUs).

NEO Compensation Aligns with Company Performance

The compensation opportunities of our executives are directly tied to the performance of the Company. Our pay-for-performance philosophy is demonstrated by the following elements of our executive compensation program for 2019:

Approximately 83% of our CEO’s 2019 total targeted pay was performance-based, and an average of approximately 71% of our other NEOs’ total targetedpay in 2019 was performance-based. The charts

below show the allocation of 2019 targeted pay across base salary, the annual cash incentive award, and thelong-term incentive award for our CEO and other NEOs.

Proxy Statement (definitive) (def 14a) (12)

In 2019, our long-term incentives continued to represent the single largest component of our CEO’s and otherNEOs’ targeted pay, representing approximately 63% and 50% of total targeted pay, respectively.

Maintaining a balanced perspective is a core part ofthe Company’s business strategy, which requires employees to take calculated risks to capitalize on anticipated changes in the Company’s numerous businesses. The Compensation Committee believes that balancing the proportion of cash and non-cash awards, as well as short-term versus long-term awards, is important to motivate performance while mitigating risk. Cash-based awards are important in motivating executives for the short-term, whilelong-term incentives focus executives who have the greatest ability to impact business results on managing the business for the long-term and reinforce the link between their earnings opportunity and the long-term growth of the Company.

Our 2019 incentive awards are directly tied to performance metrics that balance absolute and relative performance goals: EPS, cash flow conversion, organicsales growth and TSR (measured on a relative basis). We believe these are the best measures of our financial success and support the creation of stockholder value.

Role of Say-on-Pay

The Company held an advisory vote on executive compensation (say-on-pay) atthe Company’s 2019 Annual Meeting of Stockholders. The say-on-pay advisory vote received support from over 96% of the shares voted at the 2019 Annual Meeting. TheCompensation Committee believes this affirms stockholders’ support of the Company’s approach to executive compensation. Accordingly, the Compensation Committee did not make any material changes to the underlying structure of our executivecompensation program for fiscal year 2019. The Compensation Committee will continue to

32

review and consider the outcome of the Company’s say-on-pay votes when making future compensation decisionsfor the NEOs.

Short-Term Incentives

The Company administers the short-term incentive plan under the Management Incentive Compensation Plan (MICP).The amount of the annual cash bonus paid to each participant is determined under the following formula:

Annual Bonus = Base Salary x Individual TargetBonus Percentage x Business Performance Factor

Individual Target Bonus Percentage for the year is a percentage of the participant’s base salary andis based on the participant’s position and market data. The Business Performance Factor (discussed in more detail below) is calculated based on measurable corporate quantitative objectives, which are given a combined 70% weighting, and onestrategic measure with a 30% weighting.

For 2019, the measurable quantitative objectives within the Business Performance Factor were adjusted EPS andadjusted cash flow conversion. Adjusted EPS excludes from reported earnings per share the impact of acquisition and

divestiture-related income and charges, and restructuring charges (EPS Adjustments). Adjusted cash flow conversion is cash flow as a percent of net income excluding the impact of the EPSAdjustments. The payout of each quantitative objective is a function of the amount by which actual performance exceeds or falls short of goal, with a maximum payout of 200% of target for each objective.

For 2019, the 30% strategic measure was organic sales growth. Organic sales growth is a critical business metric and helps identify the underlying health ofthe Company’s businesses and management’s ability to increase sales through innovation and customer focus. Organic sales is defined as net sales of the Company adjusted to exclude the impact of foreign currency translation and sales fromacquired businesses during the first twelve months of ownership. The goal for organic sales growth is established relative to expected growth in key markets, such as industrial, health and science instrumentation, energy and fire and rescue.

For 2019, the relative weightings and theperformance against the quantitative and strategic measures resulted in a recommended Business Performance Factor of 87%, as shown in the table below.

Prior to 2018, the Company also provided short-term incentive payments under the Incentive Award Plan (IAP) to allowperformance-based bonuses to certain executives to be fully deductible under Internal Revenue Code (IRC) Section162(m). The Tax Cut and Jobs Act eliminated the deductibility of excess qualified performance-based compensation under IRCSection162(m). The MICP, under which the 2019 short-term incentives were administered, is the plan that has historically governed annual incentives for the broader executive population and also the plan under which the CFO received short-termincentive awards prior to 2018. Final awards under the MICP are calculated the same as awards under the IAP had been calculated.

2019 Long-Term Incentive Awards

Long-term incentive awards are generally made on an annual basis, or at the time of a special event (such as upon hiring or promotion). We typically grantawards at the February Board meeting each year, or the date of the annual meeting of stockholders. We attempt to make awards during periods when we do not have non-public information that could impact ourstock price. Working with its independent compensation consultant, the Compensation Committee granted long-term incentive awards to the NEOs in early 2019. Each NEO has a long-term incentive target established on an individual basis taking intoconsideration market practice for each role, and individual impact and performance.

In 2019, the NEOs received annual long-term incentive awardsconsisting of PSUs and stock options, which are intended to emphasize the link between pay and performance. The target

number of PSUs granted was determined by dividing the PSU award value by the closing price of Common Stock on the date of grant. The number of stock options granted was determined by dividing thestock option award value by the grant date fair value, utilizing the Binomial lattice option-pricing model. For additional details of the assumptions made in the valuation of such awards, see note 15 “Share-Based Compensation” of thefinancial statements in the Company’s Annual Report on Form 10-K for the year ended December31, 2019.

The Compensation Committee may grant awards above or below target based on individual and Company performance. In February 2019, the Committee reviewed theCompany’s performance compared to one- and three-year TSR, revenue and EPS growth of companies in the executive pay peer group (listed below), as well as performance against strategic goals established atthe beginning of the year. Based on this review, the Compensation Committee determined to grant above-target long-term incentive award values

to the NEOs for 2019 due to the Company’s strong performance in 2018. The Compensation Committee intends to perform a similar review annually and may adjust annual long-term incentives aboveor below target levels as appropriate to support the Company’s pay-for-performance philosophy.

2019 CEO Awards. For 2019, the Board granted Mr.Silvernail an award based on the Compensation Committee’s recommendation, whichconsidered Mr.Silvernail’s compensation position relative to the market, his outstanding performance in leading the Company, and the Company’s strong performance during the prior three-year period. The following chart shows the grantvalue recommended by the Compensation Committee and approved by the Board, and the Summary Compensation Table reported value of Mr.Silvernail’s long-term incentive awards for 2018 and 2019. The Summary Compensation Table reported valuereflects the grant date fair value determined in accordance with FASB ASC Topic 718. Similar to the other NEOs, the Compensation Committee and the Board will consider similar criteria in assessing future awards for Mr.Silvernail to determinewhether an upward or downward adjustment is warranted.

2019 COO Award. The Compensation Committee approved a special grant of PSUs to Mr.Ashleman in recognitionof his outstanding performance, with a grant value of $1,000,000. This award is subject to the same terms as the annual 2019 PSU awards.

Objectives of Long-Term Incentive Vehicles

The Compensation Committee believes that PSUs and stock options both motivate management actions that drive the creation of stockholder value and promoteexecutive stock ownership. However, each long-term incentive

component has different characteristics. The value of the PSUs after the three-year performance period is directly linked to relative TSR, as described above, as well as the stock price movementduring the performance period. Stock options provide value only to the extent that the Company’s stock price appreciates above the stock price on the date of grant.

PSU Design Features

The PSUshave a three-year performance period and measure the Company’s relative TSR against the TSR of companies in the Russell Midcap Index at the end of such period. If the Company achieves 50th percentile TSR performance as compared to the group ofcompanies, each NEO will receive the target number of performance units, paid out in shares of Common Stock. Threshold performance is at the 33rdpercentile, which will result in a payoutequal to 33% of target; performance below this level will result in zero payout. Maximum payout is 250% of the target number of shares for 80th percentile performance or higher. Payouts areinterpolated between the 33rd percentile and 50thpercentile and between the 50thpercentile and 80th percentile performance. Cumulative dividend equivalent payments will be made at the end of the performance period based on the number of shares of Common Stock received by eachexecutive.

In selecting relative TSR as the measure, the Compensation Committee noted that TSR is highly correlated with a combination of other metricsthat are important to the Company and to investors, notably: return on invested capital, operating profit margin and compound annual sales growth rate (CAGR).

Consistent with 2018, the Compensation Committee selected the Russell Midcap Index companies as the comparator group for relative TSR for the 2019 PSU grant.In selecting the Russell Midcap Index companies, the Compensation Committee’s objective was to have a sizeable group of companies similar in revenue and market capitalization to the

36

Table of Contents

Company. In addition, the Compensation Committee seeks to align with the mutual funds within the Company’s largest stockholders as they generally hold a broad range of investments coveringmultiple industries.

For the 2020 PSU grant, the Committee selected the S&P 500 index companies as the comparator group for relative TSR, as IDEX wasadded to this index in August 2019. In addition, there will be a one-year post-vest holding requirement beginning with the 2020 PSU grant, which will further align our executives’ interests with those ofshareholders.

Our PSU grant for the 2017-2019 performance period resulted in a 250% payout based on a 88% TSR, which placed the Company in the 82nd percentile of companies in the Russell Midcap Index.

SettingExecutive Compensation

Role of Compensation Committee

The Compensation Committee establishes the Company’s compensation philosophy, structures the Company’s compensation programs to be consistent withthat philosophy, and approves each element of NEO compensation. In the case of the CEO, the Board reviews, ratifies and approves compensation recommendations made by the Compensation Committee.

The Compensation Committee performs periodic reviews of executive pay tally sheets. The tally sheets outline each executive’s recent annual target andactual pay history, unvested equity holdings and termination payments under various scenarios. Data from the tally sheets is considered by the Compensation Committee when setting target total compensation. Generally, the Compensation Committeereviews and adjusts target total compensation levels annually. Actual total compensation may vary from target based on performance and changes in stock price over time.

Generally, the amount of compensation realized historically, or potentially realizable in the future, from pastequity awards does not directly impact the level at which future pay opportunities are set. When granting equity awards, the Compensation Committee considers market data and Company and individual performance.

Role of Compensation Consultant

The Compensation Committee has the sole authority to retain and replace, as necessary, compensation consultants to provide it with independent advice. TheCompensation Committee has engaged F.W. Cook as its independent consultant to advise it on executive and non-employee director compensation matters. This selection was made without the input or influence ofmanagement.

Under the terms of its agreement with the Compensation Committee, F.W. Cook will not provide any other services to the Company, unlessdirected to do so by the Compensation Committee. During fiscal year 2019, F.W. Cook provided no services to the Company other than to advise the Compensation Committee on executive and non-employee directorcompensation issues. In its review, the Compensation Committee did not identify any conflicts of interest raised by the work F.W. Cook performed in fiscal year 2019, nor any business or personal relationships that would impair F.W. Cook’sindependence.

Setting Individual Executive Pay

The Compensation Committee formulates a recommendation of CEO pay based on the financial and operating performance of the Company, the CompensationCommittee’s assessment of the CEO and a thorough review of the market benchmarking data discussed below. The CEO pay recommendations put forth by the Compensation Committee are then reviewed and subject to approval by the Board.

Table of Contents

The pay packages for the other NEOs are set by the Compensation Committee after taking into consideration therecommendations of the CEO. Individual pay decisions are based on an assessment of the individual executive, utilizing the following criteria:

1.

Contribution

•Value to IDEX; short- and long-term
•Individual contribution and impact to team performance
2.

Company Performance

•In determining the long-term incentive award value, the Compensation Committee reviews the Company’s performance relative to our peers against key performance indicators, including growth and returns and stockprice performance
•The Compensation Committee has the latitude to adjust awards up and down relative to the executives’ target

The Compensation Committee reviews pay data from two primary sources (third party surveys and peer company data) as one input in

determining appropriate target compensation levels. The Compensation Committee utilizes the expertise of its independent compensation consultant, F.W. Cook, in developing compensationrecommendations for the NEOs, including the CEO. The Compensation Committee believes that to attract and retain qualified management, total direct compensation should be competitively targeted within a range that includes the market median forcomparable positions at comparable companies, with market compensation data being only one of many factors considered by the Compensation Committee when setting the compensation levels for any particular executive. While an individualexecutive’s target compensation is positioned within the competitive range based on the individual factors listed above, actual compensation in any given year should and does vary from target based on Company and individual performance.

The Compensation Committee undertook a review and analysis to ensure that the 2019 executive compensation programs appropriately reflected the market fortalent. The Compensation Committee considered relevant market pay practices to ensure the Company’s ability to recruit and retain high performing talent across its diversified markets and global footprint. Two surveys and a peer group analysiswere utilized for the 2019 executive compensation market analysis for the NEOs.

Survey Data

The Willis Towers Watson Executive Compensation Database Survey and the Equilar Top 25 Survey were used because they include a broad range of manufacturingcompanies that are comparable to the Company in size, geography and industry.

Peer Companies

profile (ranging from customized manufacturing solutions to emerging markets in highly specialized health science technology), investment in research and development and global presence. Inaddition, the peer companies have executive officer positions that are comparable to the Company’s in terms of breadth, complexity and scope of responsibilities. F.W. Cook reviewed the composition of the peer group used to benchmark pay in 2018with the Compensation Committee. Based on that review, the companies listed below for the 2019 review are the same group of companies used to benchmark pay in 2018.

Other Compensation Components

Employee Benefits

The NEOsparticipate in group health, welfare and qualified retirement programs available to all of the Company’s employees. The NEOs also participate in nonqualified supplemental retirement plans, deferred compensation arrangements and supplementaldisability benefits. Participation in these nonqualified plans is intended to provide the NEOs with the opportunity to accumulate retirement benefits at levels above the limitations imposed by tax qualified plans. For a more complete explanation ofthese plans, see the “Narrative to 2019 Summary Compensation Table,” the “Narrative to Nonqualified Deferred Compensation at 2019 Fiscal Year End Table,” and the discussion under “Potential Payments upon Termination orChange in Control.”

Severance and Change in Control Benefits

Each of the NEOs is entitled to severance benefits under the terms of written agreements in the event that their employment is actually or constructivelyterminated without cause. The amount of the benefit, which varies with the individual, depends on whether or not the termination is in connection with a change in control. The level of each NEO’s severance benefits reflects the Company’sperception of the market for their positions at the time the agreements were put in place. For additional information, see the section below entitled “Potential Payments upon Termination or Change in Control.”

Perquisites

The CompensationCommittee believes in providing limited perquisites in line with market practice. The NEOs are provided a car allowance. The CEO is entitled to limited use of the Company’s leased aircraft fornon-business purposes. For further details on these perquisites, see the “Narrative to 2019 Summary Compensation Table” below.

Other Executive Compensation Matters

Stock Grant Practices

For allnewly issued stock option awards, the exercise price of the stock option award will be the closing price of Common Stock on the NYSE on the date of the grant. If the grant date for the annual awards falls on a weekend, the exercise price of stockoption awards will be the closing price of Common Stock on the NYSE on the last trading day preceding the date of grant.

StockOwnership

Consistent with its executive pay philosophy, the Company requires that executive officers maintain minimum ownership levels ofCommon Stock as follows:

Executive

OwnershipasaMultiple

ofBaseSalary

CEO

5x

CFO,COO

3x

OtherNEOs

2x

NEOs must comply with these ownership requirements within five years of their date of hire or promotion. Counted for purposesof satisfying ownership requirements are shares directly owned, unvested restricted shares and PSUs at target. As of December31, 2019, all NEOs met or exceeded the ownership guidelines.

Hedging and Pledging

Alldirectors and employees (including officers) of the Company are prohibited from (i)pledging Company securities (including through holding Company securities in margin accounts), and (ii)engaging in any transaction in which they mayprofit from short-term speculative swings in the value of the Company’s securities (“hedging”). For this purpose, “hedging” includes “short-sales” (selling borrowed securities that the seller hopes can be purchasedat a lower price in the future) or “short sales against the box” (selling, but not delivering,

40

Table of Contents

owned securities), “put” and “call” options (publicly available rights to sell or buy securities within a certain period of time at a specified price or the like), and otherhedging transactions designed to minimize the risk inherent in owning Common Stock, such as zero-cost collars and forward sales contracts.

Clawbacks

To the extent notin violation of applicable law, the Company reserves the right to recover, or clawback, from current or former directors and officers any wrongfully earned performance-based compensation, including stock-based awards, upon the determination by theCompensation Committee that:

•the Company’s financial statements have been restated due to material noncompliance with any financial reporting requirement;
•the cash incentive or equity compensation to be recouped was calculated on, or its realized value was affected by, the financial results that were subsequently restated;
•the cash incentive or equity compensation would have been less valuable than that actually awarded or paid based upon the application of the correct financial results; and
•the pay affected by the calculation was earned or awarded within three years of the restatement.

Tax Gross-Up Provisions

The Company has not entered into any new agreementsthat include excise tax gross-up provisions with respect to payments contingent upon a change in control since the adoption of such a policy by the Compensation Committee in February 2011. No executives areeligible for an excise tax gross-up.

The Compensation Committee has exclusive authority to modify, interpret and enforce this policy in compliancewith applicable law.

Accounting and Tax Implications — Deductibility of Executive Compensation

In developing compensation programs, the Compensation Committee reviews the estimated accounting and tax impact of all elements of the executive compensationprogram. Generally, an accounting expense is accrued over the requisite service period of the particular pay element (generally equal to the performance period) and the Company realizes a tax deduction upon payment to, or realization by, theexecutive. Previously, many of the awards granted were generally intended to satisfy the requirements for performance-based compensation under IRC Section162(m). However, the Tax Cuts and Jobs Act (the “Act”), which became law onDecember22, 2017, significantly amended IRC Section162(m). Pursuant to the Act, the definition of “covered employees” under IRC Section162(m) was amended to expand the scope of executive officers subject to the deductionlimitation, including coverage of a company’s chief financial officer. The Act also eliminated the performance-based compensation exception with respect to tax years beginning January1, 2018, but included a transition rule with respect tocompensation that is provided pursuant to a written binding contract that was in effect on November2, 2017 and not materially modified after that date. Accordingly, commencing in 2018, the Company’s tax deduction with regard tocompensation of “covered employees” is limited to $1million per taxable year for each officer.

While it is a goal of the CompensationCommittee to maximize the deductibility of executive compensation, the Compensation Committee retains the discretion to compensate officers in a manner commensurate with performance and the competitive environment for executive talent, while alsoconsistent with

41

Table of Contents

its compensation philosophy and in the Company’s and its stockholders’ best interests. Accordingly, achieving these goals may have resulted (and may continue to result, in light of therecent changes in law) in compensation that, in certain cases, is not deductible for federal income tax purposes. The Compensation Committee did not make any significant changes to the Company’s executive compensation program for 2019 inresponse to the changes to IRC Section162(m).

Risk Assessment

The Compensation Committee periodically reviews the potential risks arising from our compensation policies, practices and programs to determine whether anypotential risks are material to the Company. In approving the 2019 compensation program design, the Compensation Committee engaged in discussions with its independent compensation consultant and management regarding any potential risks and concludedthat the Company’s compensation policies and practices are designed with the appropriate balance of risk and reward in relation to the Company’s overall business strategy, do not incentivize employees, including executive officers, to takeunnecessary or excessive risks, and that any risks arising from the Company’s policies and practices are not reasonably likely to have a material adverse effect on the Company.

In this review, the Compensation Committee considered the attributes of the Company’s policies and practices, including:

•the mix of fixed and variable compensation opportunities;
•the balance between annual cash and long-term, stock-based performance opportunities;
•multiple performance factors tied to key measures of short-term and long-term performance that motivate sustained performance and are based on quantitative measures;
•caps on the maximum payout for cash incentives;
•stock ownership requirements for executives that encourage a long-term focus on performance;
•an insider trading policy that prohibits hedging and pledging;
•a clawback policy that applies to performance-based compensation, including stock-based awards, for directors and officers; and
•oversight by an independent compensation committee.

Narrative to 2019 Summary Compensation Table

Perquisites and Supplemental Disability

In addition to benefits generally available to all other U.S.-based non-union employees, the CEO andother NEOs receive an auto allowance and participate in a supplemental long-term disability program. The supplemental disability benefit is in addition to the group long-term disability benefit generally available to all U.S.-based non-union employees. The group long-term disability plan provides an annual benefit of 60% of the first $300,000 of base salary, or an annual maximum benefit of $180,000 per year. For the NEOs, the supplementalprogram provides an annual benefit of 60% of their base salary above $300,000, with a maximum supplemental benefit of $60,000 per year. The CEO is also offered the personal use of the Company leased aircraft (limited to 25 hours per year covered bythe Company and up to an additional 25 hours per year for which the CEO is required to reimburse the Company for all incremental costs related to such additional use).

Retirement Benefits

The Company maintains a tax-qualified retirement plan for employees, the IDEX Corporation SavingsPlan, in which the CEO and other NEOs participate, which consists of a 401(k) with a prescribed matching contribution (401(k)) and a defined contribution portion (Defined Contribution).

Defined Contribution

The Defined Contribution portion of the IDEX Corporation Savings Plan is an ongoing tax-qualified“defined contribution” plan that provides contributions based on a participant’s compensation and a combination of the participant’s age and years of service as shown below:

Compensation at 2019 Fiscal Year End Table

Supplemental Executive Retirement and Deferred Compensation Plan

Eligible employees may defer until a future date payment of all or any portion of their annual salary or bonus under the defined contribution portion of theSERP. Deferral elections may be made annually. These amounts are fully vested. The Company also contributes to an eligible employee’s account additional amounts, as described below, that are fully vested after the employee has completed threeyears of service.

The Company contributes an amount equal to 4% of the eligible employee’s compensation up to the IRS limit on compensation reducedby the amount of any Company matching contribution that is made to the 401(k) Plan. Additionally, the Company makes annual contributions to the accounts of eligible employees based on the employee’s compensation above the IRS limit oncompensation in the Defined Contribution Plan, determined based on the following table:

9.0

Certain eligible employees designated by the Compensation Committee, including the NEOs, also receive an additionalcontribution equal to 2% of the employee’s compensation.

Deferred Compensation Account

All amounts deferred are recorded in a memorandum account for each employee and are credited or debited with earnings or losses as if such amounts had beeninvested in either an interest-bearing account or receive an investment return as if the funds were invested in certain mutual funds, as selected by the employee. The deferred compensation credited

to the interest-bearing account is adjusted on at least a quarterly basis with hypothetical earnings equal to the lesser of the Barclays Capital Long Term Bond AAA — Corporate Bond Index asof the first business day in November of the calendar year preceding the year for which the earnings are to be credited or 120% of the long-term applicable Federal rate as of the first business day in November. The memorandum accounts are notfunded, and the right to receive future payments of amounts recorded in these accounts is an unsecured claim against the Company’s general assets.

The deferred compensation account amounts are payable upon separation of service within the meaning of IRC Section409A; however, no benefits are payableprior to the date that is six months after the date of separation of service, or the date of death of the employee, if earlier. Account balances will be paid either in a single lump sum or in up to ten substantially equal annual installments, aselected by the employee at the time he or she first becomes eligible for the Deferred Compensation Plan.

Prior to separation from service, amounts may bepaid only on the occurrence of an unforeseeable emergency, within the meaning of IRC Section409A. On the occurrence of a change in control event within the meaning of IRC Section409A, all amounts become vested and are distributed at thattime in a single lump-sum payment.

If Mr.Silvernail’s employment is terminated by the Company other than for“cause” and not in connection with a “change in control” (each as defined in the employment agreement), then, subject to his execution and non-revocation of a general release of claims andhis continued compliance with applicable restrictive covenants, he will receive (i)continuing salary payments and health benefits for 24 months following termination, (ii)a pro rata portion of his annual bonus for the year in which histermination occurs (based on the portion of the year he was employed), (iii) a payment equal to 200% of his base salary payable over 24 months commencing approximately 60 days after his termination, (iv)fully accelerated vesting and immediateexercisability of all unvested time-based equity awards (the “time-based acceleration”), and such awards will remain exercisable for one year following the date of termination of Mr.Silvernail’s employment or until expiration ofthe option term, if earlier, and (v)vesting of all unvested performance-based equity awards granted prior to February22, 2018 on the December31 next following his termination of employment with respect to that number of shares ofCommon Stock (or performance units or dividend equivalents, as applicable) based on the performance level achieved with respect to the performance goal(s) under each such award from the beginning date of the performance period applicable theretothrough such December31 (the “performance-based acceleration”). Vesting of all unvested performance-based equity awards granted on or following February22, 2018 will occur at the end of the applicable performance period withrespect to that number of shares of Common Stock (or performance units or dividend equivalents, as applicable) based on the performance level achieved through the end of such performance period.

If Mr.Silvernail’s employment is terminated due to his disability or death, he or his estate, as applicable, will receive a pro rata portion of hisannual bonus for the year in which his

termination occurs (based on the portion of the year he was employed) as well as the time-based acceleration and the performance-based acceleration with respect to performance-based equity awardsgranted prior to February22, 2018, as described above. With respect to the time-based acceleration, (i)for time-based awards granted before February22, 2018, such awards will remain exercisable for one year following the date ofsuch termination of employment or until expiration of the option term, if earlier, and (ii)for time-based awards granted on or following February22, 2018, such awards will remain exercisable for five years following the date oftermination of employment, or until expiration of the term, if earlier. Additionally, under Mr.Silvernail’s employment agreement, in the case of such termination for disability or death, vesting of all unvested performance-based equityawards granted on or following February22, 2018 will vest at the end of the applicable performance period with respect to that number of shares of Common Stock (or performance units or dividend equivalents, as applicable) based on theperformance level achieved through the end of such performance period.

If Mr.Silvernail’s employment is terminated due to his retirement (asdefined in the employment agreement), (i)he will receive the time-based acceleration, with such time-based awards granted before February22, 2018 remaining exercisable for one year following the date of termination of employment or untilexpiration of the option term, if earlier, and with such time-based awards granted on or following February22, 2018, remaining exercisable for five years following the date of termination of employment or until expiration of the option term,if earlier, and (ii)he will receive (A)the performance-based acceleration with respect to performance-based equity awards granted prior to February22, 2018 and (B)vesting at the end of the applicable performance period withrespect to that number of shares of Common Stock (or performance units or dividend equivalents, as applicable) based on the

52

Table of Contents

performance level achieved through the end of such performance period, with respect to all unvested performance-based equity awards granted on or following February22, 2018.

If Mr.Silvernail’s employment is terminated by the Company without cause or by him for “good reason” (as defined in the employmentagreement), in either case, in contemplation of or within the 24-month period following a change in control, then, subject to his execution and non-revocation of ageneral release of claims and his continued compliance with applicable restrictive covenants, he will receive (i)continuing salary payments and health benefits for 36 months following termination, (ii)a pro rata portion of his annualbonus for the year in which his termination occurs (based on the portion of the year he was employed), (iii) a payment equal to 300% of his base salary, payable over 36months commencing approximately 60 days after his termination,(iv)time-based acceleration, and (v)in lieu of performance-based acceleration, a cash payment in respect of all performance-based equity awards with respect to which he has not yet received payment, based on the performance levelachieved with respect to the performance goal(s) under each such award from the beginning date of the performance period applicable thereto through such change in control, with such cash payment adjusted to reflect hypothetical earnings (equal tothe lesser of the Barclays Long Aaa US Corporate Index or 120% of the applicable federal long-term rate, in each case, determined as of the first business day of November of the calendar year preceding the change in control and compounded) for theperiod between such change in control and the date of payment.

In addition, to the extent that any payment or benefit received in connection with achange in control would be subject to an excise tax under Section4999 of the IRC, such payments and/or benefits will be subject to a “best pay cap” reduction if such reduction would result in a greater net after-tax benefit to Mr.Silvernail than receiving the full amount of such payments.

Mr.Silvernail is subject to the non-competition and employee andbusiness non-solicitation covenants set forth in the Confidential Information, Work Product and Restrictive Covenant Agreement previously entered into between Mr.Silvernail and the Company.

Messrs. Grogan, Ashleman and Bucklew and Ms. Cade

Grogan, Ashleman and Bucklew and Ms.Cade providing for (a)severance pay in an amountequal to two times the sum of the executive’s annual base salary and target MICP bonus in the event of an involuntary termination within two years following a change in control, payable over the 24-monthperiod following termination and (b)severance pay in an amount equal to the sum of one year of salary and target MICP bonus in the event of an involuntary termination without cause other than in connection with a change in control, in exchangefor a signed release.

Equity Awards

If an outstanding award is not assumed or substituted upon a change in control or if, following a change in control, neither the Company nor its successor has equity securities that are readily tradable on aregulated securities exchange, then the awards will vest in full.

2018 and 2019 PSU Grants

Notwithstanding the foregoing, the award agreements for PSUs granted in 2018 and 2019 provide that if a change in control occurs, the grantee will receive acash payment in respect of

53

Table of Contents

such PSUs valued based on the actual level of achievement of the performance goals against target measured as of the date of the change in control, including dividend equivalents earned up to thechange in control, with such value adjusted to the date of payment to reflect hypothetical earnings (equal to the lesser of the Barclays Long Aaa U.S. Corporate Index or 120% of the applicable federal long-term rate, in each case, determined as ofthe first business day of November of the calendar year preceding the change in control and compounded) for the period between such change in control and the date of payment. The cash payment will be paid as soon as practicable following theearliest to occur of the following events: (i)if, as of the time of the change in control, the grantee is eligible for retirement, as of the date of the change in control, (ii)as of the date the grantee first becomes eligible forretirement following the change in control if that date occurs prior to the end of the performance period, (iii)if the grantee’s service is terminated by the Company without cause or by the grantee for good reason and the date oftermination occurs (or the event giving rise to good reason occurs), in each case, within 24 months following the change in control, on the date of such termination, (iv)if the grantee remains employed through the end of the applicableperformance period, as of the end of the applicable performance period, or (v)if the grantee’s employment is terminated due to death or disability prior to the end of the performance period, as of the date of death or disability.

Termination due to Death, Disability or Retirement

The award agreements for stock options and restricted stock awards provide that if the grantee’s service is terminated by reason of death, disability orretirement, the award will become fully vested and exercisable. The award agreements for the 2018 and 2019 PSU grants provide that if the grantee’s service is terminated by reason of death, disability or retirement, the PSUs and any dividendequivalents thereon will become fully vested and earned based on the

actual level of achievement of the performance goals against target measured through the end of the performance period.

SERP

Pursuant to the SERP, ifa change in control occurs then not later than the closing date for the change in control event the amount credited to each participant’s deferred compensation account shall be distributed in one lump sum in cash and/or Common Stock.

Quantification of Termination Payments and Benefits — Change in Control

The following tables set forth the amount each NEO would receive in the event of a termination of employment, as severance or as a result of acceleratedvesting if his or her employment was terminated without cause or for good reason, or for disability or death, upon a change in control or in connection with a termination of employment following a change in control, using the following assumptions:

•change in control and/or termination of employment on December31, 2019;
•accelerated vesting of options and restricted stock, and exercise of all accelerated vested options based on the closing market price of $172.00 per share of Common Stock on December31, 2019;
•accelerated vesting of PSUs and payment of cumulative dividend equivalents as valued based on performance as of December31, 2019; and
•accelerated vesting of benefits under the SERP, paid in a lump sum.

All potential termination payments setforth in the tables below reflect full payments under the potential scenarios and do not reflect any reductions that could occur if the payment is subject to excise tax under Section280G of the Internal Revenue Code.

CEO and Median Employee Pay Ratio

We believe our executive compensation program must be consistent and internally equitable to motivate our employees to perform in ways that enhancestockholder value. We are committed to providing market-competitive compensation and to internal pay equity. The following CEO to median employee pay ratio is provided pursuant to Item 402(u) of SEC RegulationS-K.

Methodology for Identifying the Median Employee

The Compensation Committee reviewed a comparison of our CEO’s annual total compensation in 2019 to that of the median employee for the same period. TheCompany used total annual cash compensation (salary/hourly earnings, commissions, bonuses paid, and allowances/fixed payments) as of December31, 2017 to determine the median employee. The Company determined there were no changes to theemployee population or employee compensation arrangements over the last two fiscal years that would result in a significant change to the pay ratio disclosure and as permitted under the Item 402(u) median employee identification instructions,elected to use the same median employee in the 2019 calculation. Under the Item 402(u)(4)(ii) (“de minimis”) exemption, the Company may exclude non-U.S. employees up to a 5% threshold whenidentifying the median employee. As noted in the Company’s 2018 Proxy Statement, in determining such median employee, the Company excluded 220 employees from the following jurisdictions, comprising less than 5% of the 6,957 total Companypopulation (with number of employees):

Australia (33)Columbia (1)Japan (33)Singapore (15)
Austria (44)Czech Republic (1)Korea (4)South Africa (1)
Belgium (15)France (5)Mexico (10)Taiwan (1)

Brazil (9)

Ireland (33)

Poland (2)

UnitedArabEmirates(13)

The 6,737 employees who were included in identifying the median employee are located in the following countries:

CanadaIndiaThe Netherlands
ChinaItalyUnited Kingdom

Germany

Switzerland

United States of America

Pay Ratio

We calculated annual total compensation for the median employee consistent with the same methodology we use for our NEOs as set forth in the 2019 SummaryCompensation Table. The annual total compensation of the CEO is $9,119,596. The median of the annual total compensation of all employees, except the CEO, is $66,703. The pay ratio is 137:1.

OurBoard of Directors recommends that you vote

FOR the approval of the Company’sexecutive compensation

PROPOSAL 2 — ADVISORY VOTE ON EXECUTIVE COMPENSATION

We are soliciting a non-binding advisory vote (say-on-pay) on the compensation of the Company’s NEOs, as described in the Compensation Discussion and Analysis, the compensation tables, and the accompanying narrative disclosure set forth in thisProxy Statement, as required under Section14A of the Securities Exchange Act of 1934, as amended.

The Company maintains a balanced approach toexecutive compensation with a mix of both cash and non-cash awards and short- and long-term incentives, with total direct compensation targeted within a range that includes market median for comparablepositions at comparable companies. Where an individual executive’s target compensation is positioned within the competitive range is based on the individual factors listed in the Compensation Discussionand Analysis. Actual compensation inany given year should and does vary from target based on Company and individual performance. In this way, the Company motivates and rewards both vital short-term performance and long-term value creation. The Board of Directors strongly endorses theCompany’s executive compensation program and recommends that the stockholders vote in favor of the following resolution:

RESOLVED, that thestockholders approve, on an advisory basis, the compensation paid to the Company’s named executive officers as disclosed in this Proxy Statement pursuant to Item 402 of Regulation S-K, including theCompensation Discussion and Analysis, compensation tables and accompanying narrative discussion contained in this Proxy Statement.

Because the vote isadvisory, it will not be binding on the Company. However, the Compensation Committee will consider the outcome of the vote in determining future compensation policies and decisions. Currently, stockholders are given an opportunity to cast anadvisory vote on this topic annually, with the next opportunity occurring in connection with the Company’s 2021 Annual Meeting of Stockholders.

Company management and the accounting firm each confirm to the Audit Committee that any non-audit service on the listis permissible under all applicable legal requirements.

The Audit Committee approves both the list of permissiblenon-audit services and the budget for such services. The Audit Committee delegates to its Chair the authority to amend or modify the list of approved permissiblenon-audit services and fees. The Chair reports any such actions taken to the Audit Committee at a subsequent Audit Committee meeting.

AGAINST the Stockholder Proposal Regarding a Report Related to Employee Representation on the Company’s Board of Directors

PROPOSAL 4 — STOCKHOLDER PROPOSAL REGARDING A REPORT RELATED TOEMPLOYEE REPRESENTATION ON THE COMPANY’S BOARD OF DIRECTORS

NorthStar Asset Management, Inc. Funded Pension Plan, P.O. Box 301840 Boston,MA 02130, the beneficial owner of 441 shares of IDEX Corporation common stock, intends to propose the following resolution at the Annual Meeting.

“Employee Representation on the Board of Directors

WHEREAS: Our company’s employees are crucial to our ability to offer shareholders continued return on their investment. A 2018 Forbes articleemphasized the need for retaining top employees by “focus[ing] on excellence in engagement”;

In August 2019, the Business Roundtable, anassociation of chief executive officers of America’s leading companies, issued a new Statement on the Purpose of a Corporation which emphasized “a fundamental commitment to all of our stakeholders.” Shareholders believe that part offulfilling the Roundtable’s commitment to “invest[] in our employees” could come from a direct line of communication between employees and the board;

In 2018, the Accountable Capitalism Act was introduced into the U.S. Congress to combat “America’s fundamental economic problems” such ascompanies’ failure to reinvest proceeds in their operations, including employees. The Act would require that “boards … include substantial employee participation … ensur[ing] that no fewer than 40% of [a board’s] directorsare selected by the corporation’s employees”;

Several European countries require employee representation on boards. Academic analysis of onesuch policy stated that it “offer[s] advantages for technical efficiency, skill development and knowledge generation through its protection of specific human capital investments”;

A recent poll found that a majority of Americans “would support allowing employees at large companies to elect representatives to those companies’boards of directors…”;

Competitiveness in our sector is evolving quickly due to technology such as artificial intelligence, machine learning,and cognitive analytics. The Manufacturing Leadership Council lists the need to “attract, develop, train, retain, and inspire both the current workforce and the next generation of employees” as a “critical issue” for themanufacturing industry; Shareholders believe that our company can advance long-term value creation through a board that includes non-management employee representation.

RESOLVED: Shareholders of IDEX Corporation urge the Board of Directors to prepare a report to shareholders describing opportunities for the company toencourage the inclusion of non-management employee representation on the Board.

62

Table of Contents

SUPPORTING STATEMENT: The report should be prepared within one year, at reasonable cost and excludingproprietary and privileged information. The Board is encouraged to assess:

1.

Any legal, technical, practical, or organizational impediments tonon-management employees gaining board nomination;

2.

Benefits and challenges associated with board membership ofnon-management employees;

3.

Opportunities or procedures through which non-management employeescould gain nomination to the board, such as allocation of board slots or special board nomination processes for non-management employees, and any needed changes to corporate governance documents to accomplishsuch changes.

For purposes of this proposal, the term “non-management employees”should be understood to be employees that are neither management nor company executives.”

OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE“AGAINST” THIS PROPOSAL FOR THE FOLLOWING REASONS:

COMPANY STATEMENT IN OPPOSITION TO THE PROPOSAL

We have best-in-class employee engagement. Engagement is a combination of satisfaction, advocacy, retention and pride, and we conduct an anonymous companywideiSay engagement survey on an annual basis to measure our employee engagement, as well as manager effectiveness and performance enablement. In 2019, we were in the top quartile (25%) of manufacturing companies in all three indices, with a responserate of 88% (best in class is 80% and above). Last year, we were in the top quartile on employee engagement and manager effectiveness. Results are shared with departmental groups and also reviewed by function and by business unit to enable targetedfocus on matters of local importance to particular teams (which avoids a “one size fits all approach”). Our latest CSR Report, which is available under the Corporate Social Responsibility link on our website at www.idexcorp.comencapsulates the many ways we are actively invested in and engage our employees in the office and in their communities.

We have many avenues for employeeengagement with management and our Board. We believe a key element of our continued success is our ability to establish a work environment where employees feel connected to the Company and recognize that their role matters. We offer numerous waysfor employees to be heard and exert influence outside of Board representation. For example, our CEO, COO and senior leaders regularly host meetings to provide business updates and answer questions posed by employees. Those questions can be presentedanonymously prior to the meetings or at the meetings themselves. Employees can provide feedback and raise any questions on any topic when completing our annual iSay survey. Our CEO regularly asks employees to email him directly with concerns orsuggestions and has a blog where he speaks on topics of interest and welcomes feedback.

We have an Open Door Policy under which we encourage employees toreport concerns, ask for guidance and voice their opinions to any member of management or Human Resources. We also have a hotline in place that allows employees to raise concerns they may have about the Company on an anonymous and confidential basis(except where prohibited by local privacy laws) 24 hours a day anywhere in the world. Management regularly, as well as Board members numerous times a year, visit manufacturing facilities and interact with employees, who have an opportunity to askquestions and give feedback. Finally, employees and all other stakeholders may contact directors in writing. We take information communicated through these multiple avenues very seriously and regularly provide responses and updates on issues thatemployees raise. In addition, we believe that information collected from employees can be valuable to decision making.

Further, we continually invest inthe training of our people, from on-the-ground learning and mentorships at our business units around the world, to our IDEX Academy programs that help develop teammembers at all levels so they can advance in their careers.

We have a thoughtful and inclusive director nominee selection process. Our existing directorselection process is designed to identify and nominate the strongest director candidates from all available sources, including our employees, and is motivated by our focus on long-term value creation. Although we currently only have one employee(our CEO, Andrew Silvernail) serving on the Board, our nominating process permits other employees, including those who are not members of management, to

64

Table of Contents

serve on the Board. Stockholders may recommend Board candidates to be considered by the Nominating and Corporate Governance Committee (Nominating Committee). The Nominating Committee is committedto giving the same consideration toward stockholder-recommended nominees as those recommended from other sources. We describe in this Proxy Statement, the process for making director nominee recommendations to the Nominating Committee.

From a process standpoint, we believe the Board and the Nominating Committee are best situated to assess the particular qualifications of potential directornominees. In selecting potential nominees for the Board, the Nominating Committee considers several qualities, including specialized expertise in the industries in which we compete, a breadth of knowledge about issues affecting us, executiveleadership in business or administrative activities, financial expertise, personal integrity, and a willingness to assume fiduciary responsibilities.

Ourcurrent process for selecting director nominees has resulted in an effective Board composed of a diverse group of leaders with a complementary blend of backgrounds, experiences, skills, expertise and perspectives. Collectively, the current membersof the Board have senior leadership experience at major domestic and international companies, key management skills, such as financial expertise in mergers and acquisitions, industrial manufacturing, organizational leadership, and expertise ininternational business; and experience on boards of other global public companies.

The proposal suggests that we allocate board slots or use a specialboard nomination process for non-management employees. This would require us to deviate from our existing thoughtful and inclusive process and seriously undercut the role of our Nominating Committee and Boardin one of the most crucial elements of corporate governance—the election of directors. This could diminish the effectiveness of our Board and would decrease the number of directors who qualify as independent.

CONCLUSION

As a result of our best-in-class employee engagement, the methods we make available to employees to communicate with management and the Board, our continual investment in the training of ourpeople, and our thoughtful and inclusive director nominee selection process (which permits employees to be recommended as potential director candidates), we believe our current director nominee selection process is sufficient and that the reportrequested by your proposal is not necessary.
