**2025 Business Highlights**

In 2025, the Company delivered a strong finish to a challenging year and achieved record gross margin for the fourth quarter ended December 31, 2025, driven by continued execution in cloud and services as well as our profitability initiatives. The Company made significant progress in key growth areas, with cloud supported by demand for software-as-a-service and infrastructure-as-a-service, and services benefiting from both organic growth and contributions from acquisitions, including our acquisitions in 2025 of Inspire11, enhancing our AI and data expertise, and Sekuro, expanding cybersecurity and digital resilience across APAC. The Company continued to expand its expertise across leading cloud platforms and enterprise solutions while strengthening its service delivery and advisory capabilities. We believe our continued focus positions us well to execute on our business goals and serve our clients' needs as market conditions evolve.

For the full year 2025, we delivered the following consolidated financial results:

&nbsp;&nbsp;&nbsp;&nbsp;• Net sales declined 5% to $8.2 billion

&nbsp;&nbsp;&nbsp;&nbsp;• Gross profit was relatively flat at $1.8 billion

&nbsp;&nbsp;&nbsp;&nbsp;• Gross margin expanded approximately 110 basis points to 21.4%

&nbsp;&nbsp;&nbsp;&nbsp;• Earnings from operations ("EFO") declined 14% to $335 million, and non-GAAP Adjusted\* EFO was relatively flat at $504 million

&nbsp;&nbsp;&nbsp;&nbsp;• Diluted earnings per share ("EPS") declined 26% to $4.86, and non-GAAP Adjusted\* diluted EPS increased 2% to $9.87

&nbsp;&nbsp;&nbsp;&nbsp;• Non-GAAP Adjusted\* return on invested capital ("ROIC") from EFO was 10.07% and from Adjusted\* EFO was 15.15%<sup>(1)</sup>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Calculated using a 26.0% tax rate.

**Executive Compensation Highlights**

**Chief Executive Officer Pay for Performance**

Our executive compensation program is focused on driving profitable growth and stockholder value creation. The Compensation Committee seeks to foster these objectives through a compensation system that focuses on variable, performance-based incentives that create a balanced focus on our short-term and long-term strategic and financial goals. As shown in the chart below, in 2025, approximately 90% of the target total direct compensation of our President and Chief Executive Officer (CEO), Joyce A. Mullen, was variable and/or "at-risk" and earned only if performance goals are met.

Our executive compensation practices include the following, each of which the Compensation Committee believes reinforces our executive compensation objectives:

---

| | |
|:---|:---|
| | **Our Executive Compensation Practices** |
| **✓** | Emphasis on at-risk compensation, with significant percentage delivered in the form of variable compensation |
| **✓** | Long-term performance objectives aligned with the creation of stockholder value |

| **✓** | Robust stock ownership guidelines |
| **✓** | Clawback policy |
| **✓** | We do not provide excessive executive perquisites |
| **✓** | We do not provide excessive severance benefits |

Extensive information regarding our executive compensation programs in place for 2025 can be found under the heading "Compensation Discussion and Analysis."

**CORPORATE GOVERNANCE**

To provide a framework for effective corporate governance, our Board of Directors has adopted Corporate Governance Guidelines. These guidelines outline the operating principles of our Board of Directors, and the composition and working processes of our Board and its committees. The Nominating and Governance Committee periodically reviews our Corporate Governance Guidelines and developments in corporate governance, and recommends proposed updates and changes to the Board for approval.

Our Corporate Governance Guidelines, along with other corporate governance documents, such as Board committee charters and our Code of Ethics and Business Practices, are available on our website at https://investor.insight.com/corporate-governance/documents-and-charters.

**Independence of Our Board of Directors**

Under our Corporate Governance Guidelines and the listing standards of NASDAQ, a majority of our Board members must be independent. The Board of Directors annually determines whether each of our directors is independent. In determining independence, the Board follows the independence criteria set forth in the NASDAQ listing standards and considers all relevant facts and circumstances.

Under the NASDAQ independence criteria, a director cannot be considered independent if he or she has one of the relationships specifically enumerated in the NASDAQ listing standards. In addition, the Board must affirmatively determine that a director does not have a relationship which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. The Board

------

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

has affirmatively determined that each of our current directors is independent under the applicable listing standards of NASDAQ, other than our President and Chief Executive Officer, Joyce A. Mullen.

**Board of Directors Leadership Structure**

Timothy A. Crown serves as the Chair of our Board of Directors and Joyce A. Mullen serves as our President and Chief Executive Officer. The Board believes that separating the roles of Chair of the Board and Chief Executive Officer, along with the use of regular executive sessions of the independent directors, provides appropriate oversight of the Company's strategic direction. Anthony A. Ibargüen serves as the Presiding Director of the Board. His responsibilities are to participate as a member of the Executive Committee; to recommend agenda items for Board meetings; and to fill in when the Chair of the Board is unavailable.

**Board Assessment**<br>

The Board engages in a robust self-evaluation process designed to elicit improvement in the effectiveness of the Board, its committees, and the individual directors. For the last several years, on an annual basis, the Company's outside counsel has distributed a self-assessment questionnaire, which was followed by an interview with each director. After compiling the results, the recommendations provided by the directors were reviewed with the Chair of the Board and the Chairs of each committee. The Chairs of the committees use the recommendations to identify areas of potential improvements for their respective committees and the Chair of the Board and the Chair of the Nominating and Governance Committee provide feedback to each individual director.

**Corporate Social Responsibility**

In 2025, the Company maintained its commitment to corporate social responsibility through environmental, social and governance ("ESG") initiatives that reflect areas of greatest relevance to Insight. These initiatives include operating with integrity, fostering employee capabilities, promoting diversity and inclusion in the workforce, data security, supporting our local communities, and minimizing our environmental impact. The Company has signed the United Nations Global Compact and supports its principles of human rights, anti-discrimination, environmental responsibility, and anti-corruption. The Board is responsible for overseeing the Company's ESG program, priorities, and initiatives and utilizes each of the committees for various aspects of the Company's overall ESG program.

Key areas of focus for the Company's ESG program include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Business Ethics and Compliance

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Data Security

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Human Capital Development

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reducing our Environmental Impact

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Community Involvement

**Board of Directors Role in Strategy**

Our Board of Directors oversees the Company's strategy. On an annual basis, the Board reviews and approves the Company's strategic plan and is involved in the Company's strategic planning process throughout its development. Throughout the past several years, the Board has been regularly involved in addressing matters of strategic importance, including evaluating and prioritizing acquisition targets, strategic partnerships, and the strategies adopted by the Company to address industry trends and opportunities.

**Board of Directors Role in Risk Oversight**

**Enterprise Risk Management Program**

Our Board of Directors oversees our Enterprise Risk Management Program (the "ERM Program"), which is designed to drive the identification, analysis, discussion and reporting of risks to the enterprise. The ERM Program encourages constructive dialog at the management and Board levels to proactively identify and manage enterprise risks. Under the ERM Program, which the Company continues to refine, management develops a comprehensive report of enterprise risks by conducting regular assessments of the business and supporting functions, including assessments of strategic, operational, financial reporting, and legal and compliance risks, and helps to ensure appropriate response strategies are in place. As part of the Company's ERM Program, the Company focuses on cybersecurity defenses, including best practices for tools, policies, procedures, and training.

Enterprise risks are considered in business decision making and as part of our overall business strategy. Our management team, including our executive officers, is primarily responsible for managing the risks associated with the operations and business of the Company. Senior management provides updates to the Audit Committee of the Board at least twice a year on matters covered by the ERM Program, and reports to the full Board on any identified high priority enterprise risks. The ERM Program has addressed the Company's use and development of artificial intelligence ("AI"), including generative AI, to ensure the Board is aware of, and able to provide oversight on the adoption and creation of best practices to mitigate exposure to, material risks that could arise from the Company's use and development of AI.

**Compensation Risk Assessment**

We annually conduct an assessment of the risks associated with our compensation practices and policies. In 2025, we determined that the risks arising from such policies and practices are not reasonably likely to have a material adverse effect on the Company. In conducting the assessment, we undertook a review of our compensation philosophies, our compensation governance structure and the design and oversight of our various compensation programs. Overall, we believe that our programs include an appropriate mix of fixed and variable

------

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

features, and short-term and long-term incentives with compensation-based goals aligning with corporate goals. Centralized oversight ensures compensation programs align with the Company's compensation philosophies and objectives, and, along with other factors, mitigates the possibility such programs would encourage excessive risk-taking.

**Code of Ethics and Business Practices**<br>

We have adopted a Code of Ethics and Business Practices, which is applicable to all of our teammates, including our Chief Executive Officer, our Chief Financial Officer (principal financial officer), our Chief Accounting Officer (principal accounting officer), and our Board members. If we make any substantive amendments to the Code of Ethics and Business Practices or grant any waiver from a provision of the code to our Chief Executive Officer, our Chief Financial Officer (principal financial officer) or our Chief Accounting officer (principal accounting officer), we will disclose the nature of such amendment or waiver on our website at https://investor.insight.com or in a Current Report on Form 8-K within four business days of such amendment or waiver. A copy of this code is available on our website at https://investor.insight.com/corporate-governance/documents-and-charters/.

**Insider Trading and Hedging Policy**<br>

We have adopted an Insider Trading Policy governing the purchase, sale, and other dispositions of our securities, which applies to all employees, officers, Board members, contractors and authorized representatives, that is reasonably designed to promote compliance with insider trading laws, rules and regulations, and any applicable Nasdaq listing standards. Our Insider Trading Policy expressly prohibits such persons from purchasing or selling our securities while in possession of material, non-public information, or otherwise using such information for their personal benefit. While our Insider Trading Policy does not apply to the Company directly, it is our general practice to follow the same guidelines and restrictions on transactions involving Company securities that apply to persons covered under the Insider Trading Policy.

Our Insider Trading Policy further prohibits employees, officers, Board members, contractors and authorized representatives from engaging in hedging transactions, short sales or other speculative transactions involving our securities. In addition, it prohibits holding Company securities in a margin account or pledging Company securities as collateral for a loan.

Our executives and Board members are permitted to enter into trading plans that are intended to comply with the requirements of Rule 10b5-1 of the Exchange Act so that they can prudently diversify their asset portfolios.

A copy of our Insider Trading Policy was filed as an exhibit to the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

**Communications with the Board of Directors**

Stockholders who would like to communicate with the Board of Directors or its committees may do so by writing to them via the Company's Corporate Secretary by mail at Insight Enterprises, Inc., 2701 E. Insight Way, Chandler, Arizona 85286. Correspondence may be addressed to the collective Board of Directors or to any of its individual members or committees at the election of the sender. Any such communication is promptly distributed to the director or directors named therein unless such communication is considered, either presumptively or in the reasonable judgment of the Company's Corporate Secretary, to be improper for submission to the intended recipient or recipients. Examples of communications that would presumptively be deemed improper for submission include, without limitation, solicitations, communications that raise grievances that are personal to the sender, communications that relate to the pricing of the Company's products or services, communications that do not relate directly or indirectly to the Company and communications that are frivolous in nature.

**Compensation Committee Interlocks and Insider Participation**

The members of the Compensation Committee during 2025 were Mr. Allen (Chair), Mses. Breard, Courage and Foutty, and Messrs. Armstrong, Baum, and Ibargüen. Mr. Baum retired from the Board and Ms. Courage

transitioned off of the Compensation Committee in May 2025. No member of the Compensation Committee was at any time during 2025 or at any other time an officer or employee of Insight, and no member had any relationship with Insight requiring disclosure. No executive officer of Insight has served on the board of directors or compensation committee of any other entity that has or has had one or more executive officers who served as a member of the Board or the Compensation Committee of Insight during 2025.

**Related Party Transactions**

**Related Party Transaction Approval Policy**

We have a written policy regarding the approval and/or ratification of related party transactions. The policy is administered by our Audit Committee and applies to any transaction or series of transactions in which the Company is a participant, the amount involved exceeds or is expected to exceed $120,000 in any calendar year and any related person has a direct or indirect interest. For purposes of the policy, "related persons" consist of the Company's directors and executive officers, any stockholder beneficially owning more than 5% of the Company's common stock, and immediate family members of any such persons.

Under the policy, the Audit Committee will review all applicable related party transactions for approval, ratification or other action unless the transaction falls within the following categories of pre-approved transactions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• employment of an executive officer if compensation is otherwise subject to disclosure requirements or approved by the Compensation Committee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• director compensation subject to disclosure requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the ordinary course of business, sales to or purchases from another company where a related party is employed or a director if the aggregate amount involved does not exceed the greater of $1 million or 2% of the other company's total annual revenues (for sales) or $50,000 (for purchases);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any charitable contribution, grant or endowment where the related party is employed or a director if the aggregate amount involved does not exceed the lesser of $10,000 or 2% of the charitable organization's annual receipts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any transaction where the related party's interest arises solely from the ownership of common stock and all holders of common stock received the same benefit on a pro rata basis;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any transaction with a related party involving the rendering of services as a common or contract carrier, or public utility, at rates or charges fixed in conformity with law or governmental authority; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any transaction with a related party involving services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture, or similar services.

We generally believe these transactions are not significant to investors because they comply with the Company's standard policies and procedures or are otherwise subject to review. Any related party transaction requiring individual review will only be approved if the Audit Committee determines that such transaction will not impair the involved person's service to, and exercise of judgment on behalf of, the Company, or otherwise create a conflict of interest that would be detrimental to the Company.

We also require that each executive officer, director and director nominee complete an annual questionnaire and report all transactions with us in which such persons (and their immediate family members) had or will have a direct or indirect material interest (except for directors' fees). Management reviews responses to the questionnaires and, if any such transactions are disclosed, they are reviewed by the Audit Committee. The types of transactions that have been reviewed in the past typically include the purchase from, and sale of products and services to, companies for which our directors serve as executive officers or directors, including purchases of marketing services for the Company's use and products for resale to clients.

**Related Party Transactions**

No related person had any direct or indirect material interest in any transaction with us required to be disclosed since the commencement of the 2025 fiscal year.

**No Stockholder Rights Plan**

**DIRECTOR COMPENSATION**

**Elements of Director Compensation**

During 2023, the Compensation Committee engaged Meridian Compensation Partners, LLC (the "Compensation Consultant") to assess the competitiveness of the Board's director compensation program relative to market practices. Following the review of the Compensation Consultant, the Compensation Committee approved for 2024 a $15,000 retainer for Audit Committee members, a $10,000 retainer for Compensation Committee members, a $5,000 retainer for Nominating and Governance Committee members and an increase to the retainer for directors by $5,000, an increase to the retainer for the Chair of the Board by $50,000 and an increase to the annual restricted stock unit ("RSU") grant by $45,000. The changes were implemented to further align the director compensation program with prevailing market and governance practices to reflect the Company's evolving business model. No changes were made to the director compensation program for 2025,

In September 2025, the Compensation Consultant conducted an updated market analysis and evaluation of the competitiveness of the Company's director compensation program. Based on the Compensation Consultant's findings and recommendations, the Compensation Committee determined that no changes to the director compensation program were warranted for 2026.

The table below sets forth the elements of our 2025 and 2026 annual compensation program for our non-employee directors.

---

| | |
|:---|:---|
| **Annual Compensation Elements** | **2025 and 2026**<br>**Amount** |
| &nbsp;&nbsp;Board Retainer | $90000 |
| &nbsp;&nbsp;Chair of the Board Retainer | $150000 |
| &nbsp;&nbsp;Audit Committee Chair Retainer | $30000 |
| &nbsp;&nbsp;Compensation Committee Chair Retainer | $20000 |
| &nbsp;&nbsp;Nominating and Governance Committee Chair Retainer | $15000 |
| &nbsp;&nbsp;Audit Committee Member Retainer | $15000 |
| &nbsp;&nbsp;Compensation Committee Member Retainer | $10000 |
| &nbsp;&nbsp;Nominating and Governance Committee Member Retainer | $5000 |
| &nbsp;&nbsp;Annual Stock Unit Grant Value | $200000 |

---

All retainers are paid quarterly in advance and, if applicable, are prorated based upon Board or chair service during the calendar year. Joyce A. Mullen, our President and Chief Executive Officer, does not receive compensation for her Board service.

The annual RSU grant vests ratably over three years on the anniversary of the grant date and entitles the director to receive shares of our common stock upon vesting. In the year of appointment to the Board, a director receives a prorated portion of the annual RSU grant value based upon the number of days between appointment and the vesting date of the most recent annual grant to incumbent directors, which prorated award vests over three years on the anniversary of the grant date. RSU awards to non-employee directors fully vest upon retirement, subject to certain conditions.

**Stock Ownership Guidelines**

The Board believes that, to more closely align the interests of our non-employee directors with the interests of the Company's other stockholders, each non-employee director should maintain a minimum level of ownership in the Company's common stock. The Compensation Committee is responsible for periodically reviewing the stock ownership guidelines for non-employee directors and making recommendations to the Board as to any changes.

------

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

Beginning in 2022, our guidelines require each non-employee director to hold shares equal to at least five times the amount of the annual retainer to be achieved over a five-year transition period. As of December 31, 2025, all non-employee directors had attained their required ownership level other than Ms. Foutty and Mr. Reichert, who are each still within the transition period, had attained their required ownership level.

**PROPOSAL 2 –** Advisory Vote to Approve Named Executive Officer Compensation

Stockholders have an opportunity to cast an advisory vote to approve the compensation of our Named Executive Officers, as disclosed in this proxy statement, pursuant to Section 14A of the Exchange Act (commonly referred to as a "say-on-pay" vote). Accordingly, we are asking stockholders to approve, on a non-binding basis, the following advisory resolution at the Annual Meeting:

*RESOLVED, that 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 the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby APPROVED.*

Although the vote is non-binding, we value feedback from our stockholders on compensation and other important matters. The Board of Directors and the Compensation Committee will consider the voting results when making future compensation decisions. At our 2025 Annual Meeting of Stockholders, approximately 98% of the votes cast by our stockholders approved the compensation of our Named Executive Officers as disclosed in the 2025 proxy statement.

As advised by our stockholders at the 2023 Annual Meeting of Stockholders (commonly referred to as a "say-on-frequency" vote) and approved by our Board, the say-on-pay vote has been held annually. The next say-on-frequency vote will occur in 2029; however, we expect to hold the say-on-pay vote on an annual basis for the foreseeable future.

In deciding how to vote on this proposal, we encourage you to review the Compensation Discussion and Analysis and 2025 Executive Compensation sections of this proxy statement for a detailed description of our executive compensation program. As described in the Compensation Discussion and Analysis, the Compensation Committee has designed our compensation program with the objective of rewarding achievement of specific financial, strategic and tactical goals by the Company and individual executives that align the interests of management with the interests of our stockholders.

**THE BOARD OF DIRECTORS RECOMMENDS A VOTE <u>FOR</u> APPROVAL, ON AN ADVISORY BASIS, OF THE RESOLUTION SET FORTH ABOVE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.**

**OVERVIEW**

**2025 Business Highlights**<br>

In 2025, the Company delivered a strong finish to a challenging year and achieved record gross margin for the fourth quarter ended December 31, 2025, driven by continued execution in cloud and services as well as our profitability initiatives. The Company made significant progress in key growth areas, with cloud supported by demand for software-as-a-service and infrastructure-as-a-service, and services benefiting from both organic growth and contributions from acquisitions, including our acquisitions in 2025 of Inspire11 LLC ("Inspire11"), enhancing our AI and data expertise, and Sekuro Limited ("Sekuro"), expanding cybersecurity and digital resilience across APAC. The Company continued to expand its expertise across leading cloud platforms and enterprise solutions while strengthening its service delivery and advisory capabilities. We believe our continued focus positions us well to execute on our business goals and serve our clients' needs as market conditions evolve.

For the full year 2025, we delivered the following consolidated financial results:

&nbsp;&nbsp;&nbsp;&nbsp;• Net sales declined 5% to $8.2 billion

&nbsp;&nbsp;&nbsp;&nbsp;• Gross profit was relatively flat at $1.8 billion

&nbsp;&nbsp;&nbsp;&nbsp;• Gross margin expanded approximately 110 basis points to 21.4%

&nbsp;&nbsp;&nbsp;&nbsp;• Earnings from operations ("EFO") declined 14% to $335 million, and non-GAAP Adjusted\* EFO was relatively flat at $504 million

&nbsp;&nbsp;&nbsp;&nbsp;• Diluted earnings per share ("EPS") declined 26% to $4.86, and non-GAAP Adjusted\* diluted EPS increased 2% to $9.87

&nbsp;&nbsp;&nbsp;&nbsp;• Non-GAAP Adjusted\* return on invested capital ("ROIC") from EFO was 10.07% and from Adjusted\* EFO was 15.15%<sup>(1)</sup>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Calculated using a 26.0% tax rate.

**2025 Say-on-Pay Vote**<br>

As noted above, in its executive compensation review process, the Compensation Committee considers whether the Company's executive compensation program is aligned with the interests of the Company's stockholders. In that respect, as part of its review of the Company's executive compensation program, the Compensation Committee considered the approval by approximately 98% of the votes cast for the Company's say-on-pay proposal at our 2025 Annual Meeting of Stockholders. The Compensation Committee determined that the Company's executive compensation philosophies, objectives and elements continued to be appropriate and did not make any changes to the Company's executive compensation program in response to the 2025 say-on-pay vote.

**WHAT WE PAY AND WHY**

**Compensation Philosophy**

Our executive compensation program is guided by our overarching philosophy of paying for performance. Consistent with this philosophy, we have designed our executive compensation program to achieve the following primary objectives:

• Provide compensation and benefit levels that will attract, retain, motivate and reward a highly-talented executive team while maintaining responsible cost management;

• Establish a direct link between our financial and operational results and achievement of strategic objectives and the compensation of our executive officers; and

• Align the interests and objectives of our executive officers with those of our stockholders by linking the long-term incentive compensation opportunities to stockholder value creation and executive officers' cash incentives to our annual performance.

**Factors Considered in Compensation Deliberations**

The Compensation Committee does not use a single method or measure in setting or approving the target total direct compensation opportunities or each individual compensation element for our executive officers. Additionally, the Compensation Committee does not weigh any one factor of pay components in comparison to the other factors. The factors below, which the Compensation Committee considers when selecting and setting the amount of compensation for each of our executive officers, provide a framework for its compensation decision-making:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our executive compensation philosophy objectives described above;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our performance against the financial and operational goals and objectives established by the Compensation Committee and our Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Each individual executive officer's qualifications, knowledge, skills, experience and tenure relative to other similarly-situated executives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The scope of each executive officer's role and responsibilities compared to other similarly situated executives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The prior performance of each individual executive officer, based on an assessment of his or her contributions to our overall performance and ability to lead his or her business unit or function and work as part of a team;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The potential of each executive officer to contribute to our long-term financial, operational and strategic objectives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The amount of compensation relative to that of our other executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our financial performance relative to our peers and broader market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The compensation practices and the positioning of each executive officer's compensation relative to our compensation peer group and the broader market based on an analysis of competitive market data;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In the case of long-term incentive compensation, the value of any outstanding vested and unvested equity awards held by each of our executive officers, including the equity awards and other long-term compensation opportunities granted to each executive officer in prior years; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The recommendations provided by our President and Chief Executive Officer regarding the compensation of our executive officers (other than the President and CEO), as described below.

**Alignment of Senior Management Team to Drive Performance**

Our financial performance goals are designed to drive profitable growth and stockholder value creation by aligning members of senior management around common financial performance goals. To drive performance against these goals, when communicating the goals to the senior management team, the Company includes extensive communications on what members of senior management, together with their teams, can do to impact achievement of these goals. We believe this understanding of the link between individual/team performance and the achievement of the Company's financial performance goals helps the entire organization focus on those actions that have the greatest potential to drive profitable growth and stockholder value creation.

**2025 Executive Compensation Decisions**<br>

Consistent with our pay-for-performance philosophy and executive compensation program objectives, in determining the 2025 adjustments to executive compensation levels and the mix of compensation elements for each Named Executive Officer, the Compensation Committee and our President and Chief Executive Officer (in making recommendations regarding Named Executive Officer compensation other than her own) considered the factors noted above in the section "Factors Considered in Compensation Deliberations."

**Base Salary**

The Compensation Committee generally sets base salaries for executives, including our Named Executive Officers, at competitive levels for executives in similar positions commensurate with their skills, experience, qualifications and marketability. The 2025 base salary for Ms. Mullen is discussed below under "Chief Executive Officer Compensation." The 2025 base salary for Mr. Morgado increased by 33% from his 2024 base salary in connection with his promotion to Chief Financial Officer of the Company, based on the Compensation Consultant's peer and broader market analysis for his new role, while the base salaries for Mr. Gregory, Ms. Vasin and Mr. Green remained unchanged from 2024. All adjustments were based on the factors noted above in the section "Factors Considered in Compensation Deliberations."

The table below sets forth the 2025 base salary level for each of our Named Executive Officers:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;**Named Executive Officer** | **2025 Base Salary** | **2025 Base Salary** |
| &nbsp;&nbsp;&nbsp;Joyce A. Mullen | $1000000 |  |
| &nbsp;&nbsp;James A. Morgado | $600000 |  |
| &nbsp;&nbsp;&nbsp;Adrian Gregory | $611000 | (1) |
| &nbsp;&nbsp;Jennifer Vasin | $475000 |  |
| &nbsp;&nbsp;Robert Green | $485000 |  |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1)&nbsp;&nbsp;&nbsp;&nbsp;While Mr. Gregory's base salary of £463,500 is shown in U.S. dollars (rounded to the nearest thousand) for presentation in this proxy statement, Mr. Gregory is paid in British pounds. Consistent with the presentation in the Summary Compensation Table, Mr. Gregory's 2025 salary was computed by multiplying the average exchange rates applicable for the quarters ended March 31, June 30, September 30, and December 31, 2025, respectively, by the compensation earned during the quarter. This results in an assumed exchange rate of $1.3178 per British pound.

**Annual Cash Incentive Awards**

We provide our senior management with short-term incentive compensation through our annual cash incentive program, the 2025 cash incentive plan. Short-term compensation under the 2025 cash incentive plan represents a significant portion of each Named Executive Officer's target total cash compensation opportunity in a given year. As discussed in more detail below, payouts under the cash incentive plan resulted from the attainment of various performance goals that were specific to the Named Executive Officer's geographic or functional responsibilities.

**2025 Cash Incentive Plan**

For 2025, the Compensation Committee provided an incentive plan for certain management level teammates, including our Named Executive Officers. Consistent with 2024, the 2025 target cash incentive compensation amounts are calculated as a percentage of base salary. The percentages are generally consistent with those utilized in 2024.

Under the 2025 cash incentive plan, defined financial objectives were established for our Named Executive Officers, and the percentages of total cash incentive compensation to be tied to each of the specified financial objectives were quantified as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Named Executive Officer** | **EFO** | **Core**<br>**Services** <br>**GP** | **Cloud GP** |
| &nbsp;&nbsp;Joyce A. Mullen | 50%<br>(IEI) | 25%<br>(IEI) | 25%<br>(IEI) |
| &nbsp;&nbsp;James A. Morgado | 50%<br>(IEI) | 25%<br>(IEI) | 25%<br>(IEI) |
| &nbsp;&nbsp;Adrian Gregory | 50%<br>(EMEA) | 25%<br>(EMEA) | 25%<br>(EMEA) |
| &nbsp;&nbsp;Jennifer Vasin | 50%<br>(IEI) | 25%<br>(IEI) | 25%<br>(IEI) |
| &nbsp;&nbsp;Robert Green | 50%<br>(IEI) | 25%<br>(IEI) | 25%<br>(IEI) |

---

For purposes of our 2025 cash incentive plan:

• Insight Enterprises, Inc. and subsidiaries ("IEI") EFO was calculated on a consolidated non-GAAP Adjusted basis, with non-GAAP Adjusted IEI EFO being defined as the Company's actual 2025 consolidated EFO, excluding certain items, specified and approved in advance by the Compensation Committee, that were not considered to be part of ongoing business (the "EFO exclusions"). Insight Europe, the Middle East and Africa ("EMEA") EFO was calculated on a non-GAAP Adjusted basis, with non-GAAP Adjusted EMEA EFO being defined as the actual 2025 EFO from the Company's EMEA operating segment, excluding the relevant EFO exclusions, on a constant currency basis.

• "IEI Core Services GP" was based on the actual 2025 IEI Core Services gross profit ("GP") results, measured against budget-based dollar targets approved by the Compensation Committee for IEI. "EMEA Core Services GP" was based on actual 2025 Core Services GP results from the Company's EMEA operating segment, on a constant currency basis, measured against budget-based dollar targets approved by the Compensation Committee for EMEA.

• "IEI Cloud GP" was based on the actual 2025 IEI cloud GP results, measured against budget-based dollar targets approved by the Compensation Committee for IEI. "EMEA Cloud GP" was based on the actual 2025 cloud GP results from the Company's EMEA operating segment, on a constant currency basis, measured against budget-based dollar targets approved by the Compensation Committee for EMEA.

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

The 2025 cash incentive plan required that the Company, or the relevant segment of the Company for which the executive has management responsibility, depending on the executive's position, achieve a threshold percentage of the budgeted amount for the particular performance measure for any payment to be made to an executive with respect to that performance measure. Therefore, it was possible that a Named Executive Officer would have different levels of achievement for each of his or her separate performance measures, and perhaps receive no payment at all, depending on performance against the goal for each performance measure. The levels of performance were set in conjunction with the Company's overall annual budget and were considered to be challenging, but achievable, given the uncertain economic environment and the tactical and strategic plans that were developed for 2025. Where actual results fell between specified performance levels, payments were calculated based on linear interpolation.

**EFO Performance**

For the 2025 consolidated IEI EFO and EMEA EFO performance measures set forth above, the threshold to receive any cash incentive was 85% of the respective budgeted EFO amount, which would result in a payout of 50% of the target cash incentive award opportunity allocated to that measure. Below 85% attainment, no payout would be received by the executive. The maximum each executive could earn, 200% of target, would result from attainment at or above 115% of the respective budgeted EFO amount.

The budgeted target, actual financial attainment and payout levels related to EFO performance measures for the 2025 cash incentive plan were as follows:

---

| | | | |
|:---|:---|:---|:---|
| &nbsp;&nbsp;**Financial Objective** | **Target** | **Actual** | **% Payout** |
| &nbsp;&nbsp;IEI EFO (non-GAAP Adjusted) | $527.7 million | $504.0 million | 85.0% |
| &nbsp;&nbsp;EMEA EFO (non-GAAP Adjusted) | $58.6 million | $56.8 million | 89.3% |

---

**Core Services GP** 

For the 2025 Core Services GP performance measures set forth above, the thresholds to receive any cash incentive was 85% of the respective budgeted Core Services GP amount, which would result in a payout of 50% of the target cash incentive award opportunity allocated to that measure. Below 85% attainment, no payout would be received by the executive. The maximum each executive could earn, 200% of target, would result from attainment at or above 115% of the respective budgeted Core Services GP amount.

The budgeted target, actual financial attainment and payout levels related to the Core Services GP performance measures for the 2025 cash incentive plan were as follows:

---

| | | | |
|:---|:---|:---|:---|
| &nbsp;&nbsp;**Financial Objective** | **Target** | **Actual** | **% Payout** |
| &nbsp;&nbsp;IEI Core Services GP | $380.0 million | $332.8 million | 58.7% |
| &nbsp;&nbsp;EMEA Core Services GP | $79.3 million | $66.5 million | —% |

---

**Cloud GP** 

For the 2025 Cloud GP performance measures set forth above, the thresholds to receive any cash incentive was 85% of the respective budgeted Cloud GP amount, which would result in a payout of 50% of the target cash incentive award opportunity allocated to that measure. Below 85% attainment, no payout would be received by the executive. The maximum each executive could earn, 200% of target, would result from attainment at or above 115% of the respective budgeted Cloud GP amount.

**Long-Term Equity-Based Incentive Program**<br>

Under our long-term equity-based incentive program, the Compensation Committee has the authority to award various forms of long-term incentive compensation grants, including stock options, RSUs and performance-based awards. The Compensation Committee's objectives for the 2025 long-term equity-based incentive awards were to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Focus executives on key performance metrics aligned with long-term stockholder value creation and the Company's long-term strategic plan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Establish a direct link between compensation and the achievement of longer-term financial and strategic objectives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Facilitate increased equity ownership by our executives; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Retain the services of our executives through multi-year vesting requirements.

For 2025, the annual long-term equity-based incentive compensation opportunities for our Named Executive Officers were granted in the form of performance-based RSUs and service-based RSUs, with the following key features to drive Company performance and align with stockholder interests:

---

| | |
|:---|:---|
| **Performance-Based RSUs** | &nbsp;&nbsp;&nbsp;• 60% of target long-term incentive opportunity of which:<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ 50% determined by measuring non-GAAP Adjusted ROIC performance goals, and <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ 50% determined by rTSR, i.e., the Company's relative TSR performance ranked on a percentile basis compared to companies defined in a custom peer group ("rTSR Comparator Companies")<br>RSUs Based on ROIC:<br>• One-year performance period (2025) with 0-200% of target payout curve (threshold payout of 12.5% of target)<br>• Earned shares vest ratably over three years on the anniversary of the grant date based upon attainment of ROIC performance goals, calculated as described below <br>RSUs Based on rTSR:<br>• Three-year performance period with 0-200% of target payout curve (threshold payout of 50% of target) with cliff vesting<br>• Earned shares vest upon certification of final percentile attainment |
| **Service-Based RSUs** | • 40% of target long-term incentive opportunity<br>• Value based on stock price at vesting<br>• Vest ratably over three years |

---

Performance-based RSUs are earned only if the applicable pre-established financial goals are achieved. Earned ROIC performance-based RSUs are subject to a two-year vesting requirement, following the one-year performance period, for a total ratable vesting period of three years from grant. The rTSR performance-based RSUs will be earned, in whole, in part or not at all, based on the Company's TSR compared to the rTSR Comparator Companies at the end of the three-year performance period, with immediate vesting at that point. To encourage over achievement of performance targets, significant upside potential exists related to the number of performance-based RSUs ultimately earned. The number of performance-based RSUs ultimately earned varies based on the achievement levels of financial performance, with greater numbers of shares awarded for higher levels of financial performance. If the Company's financial performance does not meet or exceed the pre-established threshold for the applicable period, no performance-based RSUs are earned. To encourage retention, service-based RSU awards vest over a three-year vesting period. The Compensation Committee believes that the 60/40 weighting between performance-based and service-based RSUs has demonstrated its value to stockholders over many years.

------

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

To provide a consistent long-term focus for our long-term equity-based incentive compensation and to continue to align the interests of our management and stockholders, the Compensation Committee makes annual grants of equity-based awards to our executives early in the year in connection with the annual budgeting process. Also, early in the year, the Compensation Committee approves the annual RSU program grants for management.

For 2025, the Compensation Committee determined the target value of the equity-based awards for our executive officers, including our President and Chief Executive Officer, in part based on a competitive market benchmarking analysis described in more detail in the section below labeled "How We Make Executive Compensation Decisions." Based on these studies, the Compensation Committee believes that the equity-based incentive compensation plan, including the use of performance-based RSUs, and the target level of awards granted to each executive, is competitive with market practice, and the 60/40 weighting between performance-based and service-based RSUs continues to reward our executives for performance and promotes retention of the Company's executives.

The approved dollar value of target equity-based incentive compensation amounts for the Named Executive Officers is below. Ms. Mullen's target for 2025 is further discussed below under "Chief Executive Officer Compensation."

| | |
|:---|:---|
| &nbsp;&nbsp;**Named Executive Officer** | **2025 Target** <sup>(1)</sup> |
| &nbsp;&nbsp;&nbsp;Joyce A. Mullen | $7500000 |

| &nbsp;&nbsp;Adrian Gregory  | $800000 |
| &nbsp;&nbsp;&nbsp;Jennifer Vasin | $800000 |

---

<sup>(1)</sup> &nbsp;&nbsp;&nbsp;&nbsp;Amounts do not include the one-time retention RSU awards granted to the NEOs (other than Ms. Mullen), as discussed below under "2025 Key Executive Retention and Continuity Awards."

**2025 Annual Equity-Based Incentive Plan**

The 2025 RSU awards for executive officers which are 40% service-based and 60% performance-based, were approved on December 6, 2024 for awards granted on January 1, 2025 and February 12, 2025 for awards granted on February 20, 2025. The service-based RSUs vest in three equal annual installments beginning on February 20, 2026. Half of the performance-based grants, if earned, vest in three equal annual installments beginning on February 20, 2026, and the number of RSUs to be issued, if any, will vary depending on the Company's ROIC for the fiscal year ending December 31, 2025, on a consolidated non-GAAP Adjusted basis, with non-GAAP Adjusted ROIC and invested capital being defined consistently with the computation methodology used by financial analysts that evaluate the Company. If the Company achieved less than 88% of its 2025 non-GAAP Adjusted ROIC target range, no RSUs would be issued or if the Company achieved greater than 112% of its 2025 non-GAAP Adjusted ROIC target range, 200% of the target number of RSUs would be issued. The non-GAAP Adjusted ROIC target range was set in conjunction with the Company's overall annual budget and was considered to be challenging, but achievable, given the tactical and strategic plans that had been developed for 2025. Because the Company closed the Inspire11 and Sekuro acquisitions in 2025, the Company adjusted the non-GAAP Adjusted ROIC grid. The other half of the performance-based grants, if earned, are based on achievement of rTSR over a three-year measurement period from January 1, 2025, to December 31, 2027. For purposes of the rTSR calculation, the beginning and ending stock prices are each calculated based on the 20 trading days prior to the beginning and ending dates of the performance period. Earned awards cliff vest upon certification of the level of attainment by the Compensation Committee in accordance with the following payout scale:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(1)</sup>&nbsp;&nbsp;&nbsp;&nbsp;Payout percentages will be determined based on straight line interpolation for performance between threshold and target and between target and maximum. There will be no payout for performance below the threshold.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(2)&nbsp;&nbsp;&nbsp;&nbsp;</sup>To determine the Company's applicable percentile ranking for the performance period, TSRs are calculated for the Company and each rTSR Comparator Company. The entities are arranged by their respective TSRs (highest to lowest) and the Company is ranked by percentile among the rTSR Comparator Companies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)&nbsp;&nbsp;&nbsp;&nbsp;The number of rTSR performance award grants earned and vested are determined by multiplying the target award by the rTSR Performance Multiplier achieved at the end of the performance period.

**2025 Key Executive Retention and Continuity Awards**

In December 2025, as part of our President and CEO transition planning, the Compensation Committee approved one-time stock retention and continuity awards for the Company's top executives. These awards are designed to retain critical leadership through the Company's President and CEO change and beyond. By locking in Insight's experienced executive team, Insight is safeguarding operational stability and execution of its long term strategy during this transition period. The following table sets forth the details of these one-time grants:

The one-time stock retention and continuity awards are 50% service based and 50% performance-based. The service-based RSUs will vest in three equal annual installments beginning on December 15, 2026. The performance-based RSUs, if earned, are based on achievement of absolute share price goals ("aTSR") over a three-year measurement period from December 15, 2025 through December 15, 2028, with earned awards cliff vesting on December 15, 2028 and upon certification of the level of attainment by the Compensation Committee.

**2026 Executive Compensation Program**

The design of the 2026 executive compensation program is similar to the 2025 Executive Compensation Program.

**2026 Base Salary**

The base salaries for 2026 for the Named Executive Officers were determined in part based on a competitive market benchmarking analysis described in more detail in the section below labeled "How We Make Executive Compensation Decisions." Accordingly, the base salaries for Mr. Morgado and Mr. Gregory increased 8%, while the base salaries for Ms. Vasin and Mr. Green increased 7% and 6%, respectively. Ms. Mullen's base salary remained unchanged from 2025. Ms. Mullen's base salary for 2026 is further discussed below under "Chief Executive Officer Compensation."

The table below sets forth the 2026 and 2025 annual base salary level for each of our Named Executive Officers:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;**Named Executive Officer** | **2026 Base Salary** | **2025 Base Salary** |
| &nbsp;&nbsp;&nbsp;Joyce A. Mullen | $1000000 | $1000000 |
| &nbsp;&nbsp;James A. Morgado  | $650000 | $600000 |
| &nbsp;&nbsp;Adrian Gregory <sup>(2)</sup> | $659000 | $611000 |
| &nbsp;&nbsp;&nbsp;Jennifer Vasin | $510000 | $475000 |
| &nbsp;&nbsp;&nbsp;Robert Green | $515000 | $485000 |

<sup>(1)&nbsp;&nbsp;&nbsp;&nbsp;</sup>While Mr. Gregory's 2026 and 2025 base salary of £500,000 and £463,500 are shown in U.S. dollars (rounded to the nearest thousand) for presentation in this proxy statement, Mr. Gregory is paid in British pounds. Consistent with the presentation in the Summary Compensation Table in this proxy statement, Mr. Gregory's salaries for 2025 and 2026

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

were computed by multiplying the average exchange rate for the quarters ended March 31, June 30, September 30, and December 31, 2025, respectively, by the compensation earned during the quarter. This results in an assumed exchange rate of $1.3178 per British pound.

**2026 Cash Incentive Plan**

For 2026, the Compensation Committee provided an incentive plan for certain management level teammates, including our Named Executive Officers. Consistent with 2025, the 2026 target cash incentive compensation amounts are calculated as a percentage of base salary.

The following are the target percentages of base salary for our Named Executive Officers under the 2026 cash incentive plan:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;**Named Executive Officer** | **Percentage of**<br>**Base Salary**<br>**at Target** |
| &nbsp;&nbsp;&nbsp;Joyce A. Mullen | 150% |
| &nbsp;&nbsp;James A. Morgado  | 100% |
| &nbsp;&nbsp;&nbsp;Adrian Gregory | 100% |
| &nbsp;&nbsp;&nbsp;Jennifer Vasin | 80% |
| &nbsp;&nbsp;&nbsp;Robert Green | 80% |

---

Under the 2026 cash incentive plan, defined financial objectives were established for our Named Executive Officers, and the percentages of total cash incentive compensation to be tied to each of the specified financial objectives were quantified as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Named Executive Officer** | **EFO** | **Total GP**  | **Services Revenue** |
| &nbsp;&nbsp;Joyce A. Mullen | 50%<br>(IEI) | 25%<br>(IEI) | 25%<br>(IEI) |
| &nbsp;&nbsp;James A. Morgado | 50%<br>(IEI) | 25%<br>(IEI) | 25%<br>(IEI) |
| &nbsp;&nbsp;Adrian Gregory | 50%<br>(EMEA) | 25%<br>(EMEA) | 25%<br>(EMEA) |
| &nbsp;&nbsp;Jennifer Vasin | 50%<br>(IEI) | 25%<br>(IEI) | 25%<br>(IEI) |
| &nbsp;&nbsp;Robert Green | 50%<br>(IEI) | 25%<br>(IEI) | 25%<br>(IEI) |

---

The following considerations were reflected in our 2026 cash incentive plan:

• The 2026 cash incentive plan again includes performance measures for IEI EFO and EMEA EFO calculated consistently with 2025 (see "2025 Cash Incentive Plan" under "Annual Cash Incentive Awards" above).

• Reflecting the continued focus of the Company on the strategic objective of driving growth in the higher margin business, the 2026 cash incentive plan incorporates a performance measure of Total GP for all Named Executive Officers, which is comprised of IEI Total GP and EMEA Total GP.

• Reflecting the continued focus of the Company on the strategic objective of driving growth in the services business, the 2026 cash incentive plan incorporates a performance measure of Services Revenue for all Named Executive Officers, which is comprised of IEI Services Revenue and EMEA Services Revenue.

**2026 Equity-Based Incentive Plan**

For 2026, below are the approved dollar value targets for the annual equity-based incentive compensation for each of the Named Executive Officers based on the evaluation of market data provided by the Compensation Consultant as well as the other factors noted above in the section "Factors Considered in Compensation Deliberations."

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;**Named Executive Officer** | **2026 Target** |
| &nbsp;&nbsp;Joyce A. Mullen <sup>(1)</sup> | $— |
| &nbsp;&nbsp;James A. Morgado | $1800000 |
| &nbsp;&nbsp;&nbsp;Adrian Gregory | $1000000 |
| &nbsp;&nbsp;&nbsp;Jennifer Vasin | $900000 |
| &nbsp;&nbsp;&nbsp;Robert Green | $650000 |

---

<sup>(1) &nbsp;&nbsp;&nbsp;&nbsp;</sup>Ms. Mullen did not receive 2026 equity-based awards due to her planned retirement as President and Chief Executive Officer effective upon the Board's election of her successor.

The 2026 equity-based awards for Named Executive Officers are 40% service-based and 60% performance-based and were approved on December 16, 2025 for awards granted on January 1, 2026 and February 13, 2026 for awards granted on February 20, 2026. The service-based RSUs will vest in three equal annual installments beginning on February 20, 2027. The performance-based grants earned based on non-GAAP Adjusted ROIC will vest in three equal annual installments beginning on February 20, 2027. The performance-based grants earned based on rTSR will cliff vest upon certification of the level of attainment by the Compensation Committee after January 1, 2029. Vesting for the rTSR grants does not occur until after performance has been determined and certified by the Compensation Committee within 60 days following the end of the three-year performance period.

The Company's Adjusted ROIC for the fiscal year ending December 31, 2026 is calculated on a basis consistent with how it was calculated for 2025. If the Company achieves below 88% of its 2026 non-GAAP Adjusted ROIC target range, no RSUs will be issued or if the Company achieves greater than 112% of its 2026 non-GAAP Adjusted ROIC target range, 200% of the target number of RSUs will be issued. The non-GAAP Adjusted ROIC target range was set in conjunction with the Company's overall annual budget and was considered to be challenging, but achievable, given the tactical and strategic plans that were developed for 2026.

The Company's rTSR compares Insight's 3-year cumulative stockholder return (i.e., change in stock price plus dividends which are assumed to be reinvested) versus each company in the 2026 rTSR peer group. The peer group is a custom group of 30 distribution and technology companies. The performance period is January 1, 2026 through December 31, 2028. For purposes of the rTSR calculation, the beginning and ending stock prices are each calculated based on the 20 trading days prior to the beginning and ending dates of the performance period. The table below sets forth the award payout schedule for our Named Executive Officers under the rTSR metric.

---

| | |
|:---|:---|
| **Percentile Rank** | **Percentage of Payout at Target**<sup>(1)</sup> |
| ≥ 80th percentile | 200% |
| 55th percentile | 100% |
| 30th percentile | 50% |
| < 30th percentile |  |

---

(1) &nbsp;&nbsp;&nbsp;&nbsp;The payout percentage of target rTSR awards earned between award levels interpolates linearly with the Company's rTSR percentile rank among the defined peer group.

In determining the amount of equity-based incentive compensation for 2026, the Compensation Committee considered its goal to provide retention value for senior executives through stock price improvement, which the Compensation Committee believes aligns the interests of management and the stockholders. Based on the Compensation Committee's review of the Compensation Consultant's analysis of the competitiveness of the

------

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

Company's compensation levels, including its equity-based award levels, the Compensation Committee's review of the Company's 2026 budget, and in connection with implementation of the Company's strategic plan, the Compensation Committee awarded service-based and performance-based RSUs, as described above, to each of our Named Executive Officers.

**Chief Executive Officer Compensation**

The Compensation Committee determines compensation for the President and Chief Executive Officer using the same criteria it uses for other executives, placing relatively less emphasis on base salary and, instead, creating greater opportunities for performance-based short-term and long-term incentive compensation (cash and equity, respectively).

Ms. Mullen's base salary for 2025 was $1,000,000, remaining unchanged from her base salary in 2024. Ms. Mullen's target annual cash incentive award opportunity is reflected as a percentage of base salary, which remained consistent at 150%, resulting in Ms. Mullen's 2025 target annual cash incentive award being $1,500,000. The dollar value of 2025 target equity-based compensation awards approved by the Compensation Committee for Ms. Mullen increased 15% from 2024 to $7,500,000. As a result, target total direct compensation opportunity for 2025 was $10,000,000 (compared to $9,000,000 in 2024). Ms. Mullen's actual annual direct compensation earned for 2025 was $8,756,781, or approximately 88% of the total target.

For 2026, Ms. Mullen base salary of $1,000,000 remains unchanged from 2025. Ms. Mullen's target annual cash incentive award opportunity is reflected as a percentage of base salary, which remained consistent at 150%, resulting in Ms. Mullen's 2026 target annual cash incentive award also remaining unchanged at $1,500,000. Ms. Mullen did not receive equity-based awards for 2026. As previously announced, Ms. Mullen intends to retire as our President and Chief Executive Officer, effective upon the election of her successor, which is set to occur on April 13, 2026. In accordance with the terms of Ms. Mullen's new employment agreement entered into on November 7, 2025, upon the date her successor assumes the position of Chief Executive Officer, Ms. Mullen will continue to serve as an employee of the Company in the capacity of Executive Vice President, Strategic Development through March 31, 2028. Upon her transition to service as Executive Vice President, Strategic Development, Ms. Mullen will receive an annual base salary of $300,000 and will continue to participate in the Company's benefit plans. Ms. Mullen's base salary and cash incentive in connection with her role as our President and Chief Executive Officer will be prorated through her last day service as our President and Chief Executive Officer.

**Other Elements of Our Executive Compensation Program**<br>

**Severance Arrangements and Change in Control Provisions**

Severance and change in control provisions are designed to facilitate the Company's ability to attract and retain executives as the Company competes for talented employees in a marketplace where such protections are commonly offered. Severance benefits are designed to provide benefits to ease an executive's transition following an employment termination by the Company due to changes in the Company's employment needs. Change in control benefits are intended to encourage executives to remain focused on the Company's business in the event of rumored or actual fundamental corporate changes. The Company applies double-trigger equity vesting acceleration in the event of a change-in-control. Both severance and change in control benefits are often a critical part of an executive's initial compensation package, and key executives may not have accepted our offers of employment if we had not provided market-level severance and change in control benefits. See further detail under the section entitled "Employment Agreements, Severance and Change in Control Provisions."

**Other Benefits**

Our Named Executive Officers participate in benefit plans generally available to all of our teammates, including medical, health, life insurance and disability plans. Our U.S.-based Named Executive Officers are also eligible to participate in the Company's 401(k) plan and receive Company matching contributions, to the extent made by the Company, which are generally available to our U.S. teammates. These benefits are part of our broad-based total compensation programs offered in the geography in which each of the executives resides.

------

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

We provide our executive officers with limited perquisites, and we believe they are reasonable and in the best interests of the Company. We promote wellness initiatives in our employee health insurance plans and make premium payments for long-term disability insurance for all of our Named Executive Officers in the United States. The costs of perquisites and other personal benefits provided to our Named Executive Officers during 2025 are included in the Summary Compensation Table in this proxy statement and identified in the footnotes thereto.

**Clawback Policy**

The Compensation Committee adopted an incentive compensation recovery, or "clawback," policy, effective October 2, 2023, that permits the Company, under certain circumstances, to recover incentive compensation received by an executive officer in the event of an accounting restatement that exceeds the amount of incentive compensation that would have been received had it been determined based on restated amounts. The Company's clawback policy fully aligns with the requirements of the NASDAQ listing standards and supersedes and replaces the Company's prior clawback policy.

**Stock Ownership Guidelines**

The Compensation Committee believes that, in order to more closely align the interests of our executive officers with the interests of the Company's other stockholders, all executives should maintain a minimum level of equity interests in the Company's common stock. The Compensation Committee amended its stock ownership guidelines in February 2023 to require ownership of six times base salary for our President and Chief Executive Officer and three times base salary for our other executive officers to be achieved over a five-year transition period. Failure to meet or show sustained progress toward meeting the stock ownership guidelines may result in a reduction of future long-term incentive grants and may result in a requirement to retain some or all of the shares of common stock attained through Company grants of equity until the stock ownership guidelines are attained. As of December 31, 2025, all Named Executive Officers have until February 9, 2028 to attain the required ownership level under the amended guidelines.

**Hedging, Short Sales and Pledging Policies**

Our executive officers are prohibited from hedging and short sales transactions with respect to our securities. In addition, our executive officers are prohibited from pledging our securities. For a further description of these policies, see "Corporate Governance — Insider Trading and Hedging Policy."

**Tax Considerations**

For our 2025 tax year, Section 162(m) ("162(m)") of the Internal Revenue Code ("IRC") generally prohibits a public company from taking an income tax deduction for compensation over $1 million paid to the principal executive officer, the principal financial officer and any one of the three highest paid executive officers as of the close of the applicable taxable year. Although the tax benefits associated with performance-based compensation programs previously allowed under 162(m) generally have been eliminated, the Compensation Committee believes that a pay-for-performance model incentivizes our executive officers to achieve objectives that are aligned to the creation of stockholder value, irrespective of tax deductibility.

**Equity-Based Award Grant Policy and Grant Practices**

Our equity-based award grant policy governs the timing and establishes certain internal controls over the grant of equity-based awards, including stock options (which we have not granted since 2007), restricted stock and restricted stock units. The policy requires that the Compensation Committee, or Board, generally approves the grant, including target value, of annual equity-based awards for our executive officers, including each of the Named Executive Officers, at its February meeting each year. In special circumstances, such as the hiring or promotion of an individual, or when the Compensation Committee determines it is in the best interest of the Company, the Compensation Committee may approve grants of equity-based awards at other times. Our equity-based award grant policy prohibits the Company from purposely accelerating or delaying the public release of material information in consideration of a pending equity award in order to allow the recipient to benefit from a more favorable share price. Our equity-based award grant policy further requires that the Compensation Committee and the Board consider, with management's advisement, whenever material non-public information is planned to be released to the public in close proximity to the grant of an equity award.

**HOW WE MAKE EXECUTIVE COMPENSATION DECISIONS**

The Compensation Committee believes that our executive compensation program should reward actions and behaviors that drive profitable growth and stockholder value creation. The Compensation Committee seeks to foster these objectives through a compensation system that focuses heavily on variable, at-risk performance-based incentives that create a balanced focus on our short-term and long-term strategic and financial goals. The Compensation Committee's objective is to implement an executive compensation program that drives above-market results and that is built upon our long-standing executive compensation philosophies and objectives, as described in "Compensation Philosophy" and outlined below, which we believe are key contributors to our success:

| **✓** | **✓** | **✓** |
| **Attract and Retain Talent.**<br>Executive compensation should be market-competitive in order to attract, retain and motivate talent with a performance- and service-driven mindset. | **Pay for Performance.**<br>A significant percentage of an executive's compensation should be at-risk and directly aligned with Company performance, with a balance between short-term and long-term incentives. | **Align with Stockholder Interests.**<br>Executives' interests should be aligned with stockholder interests through Insight equity ownership. |

---

**Role of the Board, Compensation Committee and Our Named Executive Officers**<br>

The Compensation Committee is responsible for determining the annual cash compensation of our President and Chief Executive Officer and each of our other Named Executive Officers. In the case of the 2025 long-term equity-based incentives, the Compensation Committee was responsible for recommending to the Board for approval the targeted grant levels for each of our Named Executive Officers. Based on the recommendations of the Compensation Committee, the Board approved the 2025 long-term equity-based incentive awards. In setting or recommending, as applicable, the compensation of our President and Chief Executive Officer, the Compensation Committee considers its review of the President and Chief Executive Officer's performance. In setting or recommending, as applicable, the compensation of our other Named Executive Officers, the Compensation Committee considers the President and Chief Executive Officer's review of each executive officer's performance and her recommendations with respect to their compensation. The Compensation Committee's responsibilities regarding executive compensation are further described in the "Corporate Governance" section of this proxy statement.

**Guidance from the Compensation Committee's Independent Compensation Consultant**<br>

The Compensation Consultant provides executive compensation consulting services to the Compensation Committee. The Compensation Committee engaged the Compensation Consultant to review the Company's executive compensation program for 2025 and 2026.

The Compensation Consultant provided services in connection with the development of the 2025 executive compensation plan, including a review of multiple comparison groups' compensation data, awards under our long-term equity-based incentive program, the setting of performance goals in our variable incentive plans, and trends in executive compensation, as well as analysis of the competitiveness of the President and Chief Executive Officer's compensation. The Compensation Consultant also provided an assessment of the competitiveness of the Board's compensation program against market (see "Director Compensation" elsewhere

------

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

in this proxy statement for additional information). The Compensation Consultant is retained by and reports to the Compensation Committee and, at the request of the Compensation Committee, participates in committee meetings. The Compensation Committee reviewed the independence of the Compensation Consultant under NASDAQ and SEC rules and concluded that the work of the Compensation Consultant has not raised any conflict of interest.

**Comparison Peer Groups**

To obtain a broad view of competitive practices among industry peers and competitors for executive talent, the Compensation Committee annually reviews market data from multiple peer groups of companies as well as general industry survey data to obtain a broad view of competitive practices among industry peers and competitors for executive talent. As described above, the Compensation Committee has asked the Compensation Consultant to advise the Compensation Committee on all matters related to executive compensation.

To help assess pay levels and set compensation for 2025 and 2026, the Compensation Consultant advised the Compensation Committee on a wide range of issues, including, without limitation, competitive market data at the time of hire and at the time of promotions for specific positions. Additionally, the Compensation Consultant conducted a review of multiple comparison groups and relevant data sources, such as existing pay levels and other publicly available information about trends in executive compensation (e.g., Equilar, AON, and data sourced from proxy statements). To assist the Compensation Committee in evaluating and determining executive compensation for 2025, the Compensation Consultant used a single peer group of 21 technology companies to better align with the Company's evolving business model (the "Technology Solutions Peer Group" or the "comparison group"), as described below. The comparison group was approved by the Compensation Committee based upon management's and the Compensation Committee's review of competitors and relevant industry comparisons, and on the advice of the Compensation Consultant.

The primary characteristics of the Technology Solutions Peer Group were:

**Peer Companies - 2025 Executive Pay Levels**

The companies included in the Technology Solutions Peer Group for 2025 were as follows:

---

| | |
|:---|:---|
| **Technology Solutions Peer Group** | **Technology Solutions Peer Group** |
| Arrow Electronics, Inc. | Gen Digital Inc. |
| Avnet, Inc. | Hewlett Packard Enterprise |
| Belden Inc. | Jabil Inc. |

| CDW Corporation | NCR Voyix Corporation |
| Cognizant Technology Solutions | PC Connection, Inc. |
| CommScope Holding Company, Inc. | Rackspace Technology, Inc. |
| DXC Technology Company | Sanmina Corporation |
| EPAM Systems, Inc. | ScanSource, Inc. |
| ePlus Inc | WESCO International, Inc. |
| Flex Ltd. | |

---

The companies included in the Technology Solutions Peer Group for 2025 are all publicly-traded companies with annual revenues of less than $31 billion. Based on data compiled by the Compensation Consultant at the time the peer group was approved by the Compensation Committee, the median revenue of the comparison group in 2025 was $6.7 billion, and the median market cap in 2025 was $5.7 billion.

In preparation for its 2026 executive compensation decisions, the Compensation Committee reviewed the Compensation Consultant's December 2025 assessment and concluded that the Technology Solutions Peer Group remains appropriate for the Company's size and complexity. The only change was the removal of Hewlett Packard Enterprise. The Compensation Committee believes this revised peer group of 20 companies provides a meaningful benchmark for current pay practices, compensation levels, and broader compensation trends across the key segments in which the Company operates, and is appropriate for assessing 2026 executive compensation.

<sup>(1)</sup> These amounts reflect the grant date fair value of the equity-incentive awards granted to our Named Executive Officers computed in accordance with FASB ASC Topic 718. The incentive awards are granted in the form of services-based RSUs and performance-based RSUs.

For 2025 awards granted in the form of service-based RSUs and performance-based RSUs subject to ROIC, the grant date fair value was calculated based on the closing price of the Company's common stock on February 20, 2025 of $166.00 per share multiplied by the number of shares subject to the RSU awards. For 2025 awards granted in the form of performance-based RSUs subject to rTSR, the grant date fair value was computed on the probable outcome of the performance conditions based on a Monte Carlo simulation and the grant date estimate of compensation cost to be recognized over the performance period which was 126.00% of target or $191.65 per share for the January awards granted. For 2025 awards granted in the form of performance-based RSUs subject to aTSR, the grant date fair value was computed on the probable outcome of the performance conditions based on a Monte Carlo simulation and the grant date estimate of compensation cost to be recognized over the performance period which was 56.71% of target or $45.05 per share for the December awards granted. With respect to the performance-based RSUs subject to rTSR and aTSR, they are subject to market conditions as defined under FASB ASC Topic 718 and are not subject to performance conditions as defined under FASB ASC Topic 718 and, therefore, they have no maximum grant date fair values that differ from the grant date fair values. For the 2025 performance-based RSUs subject to ROIC, the value in the table represents target level of achievement, which is considered the probable outcome. The maximum award attainable was 200% of the target number of shares subject to the performance-based RSU awards. For Ms. Mullen, Ms. Morgado, Mr. Gregory, Ms. Vasin and Mr. Green, the maximum value of RSUs on the grant date (performance-based and service-based) assuming the maximum achievement at the highest level of performance was $10,335,456, $3,496,918, $2,669,748, $2,277,978, and $1,726,706, respectively. As discussed in the CD&A section of this proxy statement, the actual award level for performance-based RSUs subject to ROIC for all Named Executive Officers for 2025 was 50% of the target number.

For all three years for which grant date fair value is presented in the table above, no estimate of forfeitures is included in these amounts, nor were any actual forfeitures included in these amounts.

<sup>(2)</sup> Non-Equity Incentive Plan Compensation represents bonuses earned by Named Executive Officers under the 2025, 2024 and 2023 annual cash incentive plans, respectively. Bonus amounts under the 2025 annual cash incentive plan were determined as more specifically discussed under "Annual Cash Incentive Awards" included elsewhere in this proxy statement. The cash incentive plan compensation for 2025 was paid to the Named Executive Officers prior to March 17, 2026.

<sup>(3)</sup> All Other Compensation for 2025 represents payments to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ms. Mullen for expenses incurred related to matching contributions to her 401(k), a discretionary contribution to her health savings account, premium payments made on her behalf for long-term disability insurance and value received related to an annual sales incentive trip. We consider premium payments for long-term disability insurance and the value received related to an annual sales incentive trip, which did not exceed $10,000, to be perquisites.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Morgado for expenses incurred related to matching contributions to his 401(k), a discretionary contribution to his health savings account and premium payments made on his behalf for long-term disability insurance. We consider premium payments for long-term disability insurance, which did not exceed $10,000, to be perquisites.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Gregory for expenses incurred related to matching contributions and other payments to his retirement funds, a discretionary contribution to his health savings account and premium payments made on his behalf for long-term disability insurance. We consider premium payments for long-term disability insurance and expenses relating to the use by Mr. Gregory of his car, which did not exceed $10,000, to be perquisites.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ms. Vasin for expenses incurred related to matching contributions to her 401(k), premium payments made on her behalf for long-term disability insurance and a discretionary contribution to her health savings account. We consider premium payments for long-term disability insurance, which did not exceed $10,000, to be perquisites.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Green for expenses incurred related to matching contributions to his 401(k), premium payments made on his behalf for long-term disability insurance and a discretionary contribution to his health savings account. We consider premium payments for long-term disability insurance, which did not exceed $10,000, to be perquisites.

<sup>(4)</sup> Mr. Gregory joined the Company as President, EMEA effective January 2, 2023. Mr. Gregory is a resident of the United Kingdom and was paid in British pounds. The salary and all other compensation amounts included in the table above were determined by multiplying the average exchange rates applicable for the quarters ended March 31, June 30, September 30, and December 31, 2025, 2024 and 2023, respectively, by the compensation earned during the quarter. This results in an assumed exchange rate of $1.3178, $1.2782 and $1.2432 per British pound for the years 2025, 2024 and 2023, respectively. The non-equity incentive plan compensation amount included in the table above was determined by multiplying the British pounds paid by the exchange rate applicable on the date paid of $1.3480, $1.2632 and $1.2679 per British pound for the years 2025, 2024 and 2023, respectively.

<sup>(1)</sup> Represents awards under the 2025 cash incentive plan discussed under the heading "2025 Cash Incentive Plan" of the CD&A section in this proxy statement. Threshold represents the amount that would have been payable had the minimum level of achievement for each defined performance measure been achieved. It is possible for the award to be zero if performance falls below the threshold levels. The maximum estimated future payouts under non-equity incentive plan awards was computed as 200% of the target cash incentive compensation component that was based exclusively on the specific financial objectives for each Named Executive Officer. Actual amounts are reflected in the Summary Compensation Table in the Non-Equity Incentive Plan Compensation column, and there are no future payouts related to these awards.

<sup>(2)</sup> Pursuant to the 2025 equity-based incentive compensation program, grants of service-based and performance-based RSUs to our Named Executive Officers were made on January 1, 2025, February 20, 2025, and December 15, 2025, as applicable. For the January 1, 2025, February 20, 2025 and December 15, 2025 awards that were subject to performance conditions, the maximum award attainable was 200% of the target number of RSU awards. Threshold represents the amount of RSUs that would have been granted had the minimum level of achievement for the defined performance measure been achieved. It is possible for the award to be zero if performance falls below the threshold level. See "2025 Annual Equity-Based Incentive Plan" included elsewhere in this proxy statement for a discussion of the performance criteria applicable to the performance-based RSUs. The ROIC grid is adjusted after an acquisition closes, using a prorated update to Invested Capital and the post-close budgeted earnings. The actual award level for 2025 performance-based RSUs subject to ROIC was 50% of the target number of RSUs. The actual award level for the 2025 performance-based

RSUs subject to rTSR will be determined as of December 31, 2027. The actual award level for the 2025 performance-based RSUs subject to aTSR will be determined as performance levels are achieved.

<sup>(3)</sup> For the 2025 performance-based RSUs subject to ROIC, the grant date fair value of the annual plan-based awards was calculated based on the closing price of the Company's common stock on February 20, 2025 of $166.00 per share multiplied by the target number of performance-based RSUs, as the target was considered to be the probable outcome as of the grant date. The actual award level for 2025 was 50% of the target number of performance-based RSUs. For the 2025 performance-based RSUs subject to rTSR and aTSR, the grant date fair value was computed in accordance with FASB ASC Topic 718. For the 2025 awards that did not have performance conditions and all other stock awards granted in 2025, the grant date fair value for the awards was calculated based on the closing price of the Company's common stock on February 20, 2025 of $166.00 per share and on December 15, 2025 of $79.44, respectively, multiplied by the number of service-based RSUs granted, as applicable. The grant date fair values of stock awards are also reflected in the Summary Compensation Table.

(1)Under various service-based equity incentive compensation programs, our Named Executive Officers have received varying levels of grants of (i) service-based RSUs that vest ratably over three years, (ii) performance-based RSUs based on ROIC with a one-year performance period, with earned shares that vest ratably over three years, (iii) performance-based RSUs based on rTSR with a three-year performance period with cliff vesting for earned shares and (iv) performance-based RSUs based on aTSR with a three year performance period with cliff vesting for earned shares.

Pursuant to the 2025 equity-based incentive compensation program, grants of service-based and performance-based RSUs to our Named Executive Officers were made in January and February 2025. For the 2025 performance-based awards subject to ROIC, the number of actual performance-based RSUs ultimately awarded was at 50% of the target. As of December 31, 2025, the RSUs effectively became service-based RSUs, vesting ratably over the three years following the grant date. For 2025 performance-based awards subject to rTSR, the performance measure set for these shares was based on the Company's rTSR performance over the period January 1, 2025 through December 31, 2027 compared to the rTSR Comparator Companies. For 2025 performance-based awards subject to aTSR, the performance measure set for these shares was based on the Company's aTSR performance over the period December 15, 2025 through December 15, 2028.

Pursuant to the 2024 equity-based incentive compensation program, grants of service-based and performance-based RSUs to our Named Executive Officers were made in January and February 2024. For the 2024 performance-based awards subject to ROIC, the number of actual performance-based RSUs ultimately awarded was at 100% of the target. As of December 31, 2024, the RSUs effectively became service-based RSUs, vesting ratably over the three years following the grant date. For 2024 performance-based awards subject to rTSR, the performance measure set for these shares was based on the Company's rTSR performance over the period January 1, 2024 through December 31, 2026.

Pursuant to the 2023 equity-based incentive compensation program, grants of service-based and performance-based RSUs to our Named Executive Officers were made in February 2023. For the 2023 performance-based awards subject to ROIC, the number of actual performance-based RSUs ultimately awarded was at 100% of the target. As of December 31,

**2025 Chief Executive Officer Pay Ratio**<br>

Pursuant to SEC rules, we are required to disclose the ratio of our median employee's annual total compensation to the annual total compensation of our President and Chief Executive Officer for 2025. We calculated the total compensation for both using the same methodology. The 2025 annual total compensation for the President and Chief Executive Officer and our median employee were $10,498,947 and $67,704, respectively. The ratio of annual total compensation for our President and Chief Executive Officer to that of our median employee was 155.1 to 1.

In determining the median employee for 2025 we used the same Company employee as in 2024 and 2023 given that there has been no change in the Company's employee population or employee compensation arrangements from 2023 to 2025 that would reasonably be expected to significantly change the pay ratio disclosure. In determining the median employee for 2023, we referred to our worldwide payroll rosters of employees on December 31, 2023, which included information on base wages, bonuses, and commissions. The payroll rosters totaled to 14,437 employees, consisting of 6,865 U.S. employees and 7,572 non-U.S. employees. In accordance with the "*de minimis*" exemption adjustment permitted under SEC rules, employees from the following countries, comprising less than 5% of the total population of employees, were excluded from the population, based on management's judgment: Austria (19 employees), Belgium (39 employees), China (48 employees), Hong Kong (29 employees), Ireland (5 employees), Italy (94 employees), New Zealand (25 employees), Singapore (22 employees), Spain (151 employees), Sweden (29 employees), and Switzerland (3 employees).

Compensation amounts for employees newly hired during 2023 were annualized based on actual pay in 2023.

**Pay Versus Performance**

As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between "compensation actually paid" to our President and CEO and to our non-CEO Named Executive Officers and certain financial performance of the Company. Compensation actually paid, as determined under SEC requirements, does not reflect the actual amount of compensation earned by or paid to our Named Executive Officers during a covered year. For further information concerning the Company's pay-for-performance philosophy and how the Company aligns executive compensation with the Company's performance, refer to the Compensation Discussion and Analysis.

**Employment Agreements, Severance and Change in Control Provisions**

Our employment agreements with our executive officers and our incentive compensation plans reflect our compensation philosophy. The employment agreements for our Named Executive Officers provide for continually renewing one-year terms. All change in control benefits are "double trigger" (which means that they are triggered by two events, a change in control of the Company plus a triggering termination under the change of control agreement), including stock awards under the terms of the 2020 Omnibus Plan. Additionally, beginning with grants to all employees in February 2015, upon termination of service by reason of death, any portion of service-based RSUs and, after the completion of the performance period for all performance-based awards, any portion of performance-based awards remaining unvested on that date, which would have vested through the first anniversary of the date of death become fully exercisable and vested effective immediately prior to the employee's death.

&nbsp;&nbsp;&nbsp;&nbsp;(ii)A severance payment upon termination of employment by Ms. Mullen for "good reason," as defined in the agreement, payable upon termination in a lump sum, equal to the amount that would be payable based on a $300,000 base salary through March 31, 2028 and a lump sum cash amount equal to the value of any granted but unvested RSUs as of her termination date.

&nbsp;&nbsp;&nbsp;&nbsp;(iii)In the event of Ms. Mullen's termination as a result of "disability," as such term is defined in the agreement, or death, she or her estate, as the case may be, will be entitled to a lump sum payment the value of any granted but unvested RSUs as of her termination date.

(1)Represents the number of underlying shares of common stock at the target award level associated with outstanding RSUs under approved plans. For outstanding performance-based RSUs, if the maximum award levels are achieved, the number of securities to be issued upon exercise of the outstanding rights would be 708,232 and 1,569,704 securities would remain available for future issuance under the 2020 Omnibus Plan. The RSUs are excluded from the calculation of the weighted average exercise price because they have no exercise price associated with them.

(2)Includes 1,629,546 shares of common stock remaining available for issuance under the 2020 Omnibus Plan and 1,686,369 shares of common stock available for future issuance under the Company's Employee Stock Purchase Plan.

**Employee Stock Purchase Plan**

The Employee Stock Purchase Plan (the "ESPP") is a broadly-based stock purchase plan in which any eligible employee may elect to participate by authorizing the Company to make payroll deductions in a specific amount or designated percentage to pay the exercise price of an option. In no event will the ESPP permit an employee to purchase common stock with a fair market value in excess of $25,000 in any calendar year. First purchase under the ESPP was on February 16, 2024.

There are four three-month offering periods in each calendar year beginning on February 18, May 18, August 18, and November 18, respectively. The purchase price of shares offered under the ESPP is an amount equal to 95% of the fair market value of the common stock on the date of purchase. The ESPP is designed to comply with Section 423 ("Section 423") of the Internal Revenue Code of 1986, as amended, and thus is eligible for the favorable tax treatment afforded by Section 423.

**PROPOSAL 3 –** Ratification of Independent Registered Public Accounting Firm

The Board of Directors and the Audit Committee recommend that the stockholders ratify the selection of KPMG LLP ("KPMG") as the Company's independent registered public accounting firm for the year ending December 31, 2026. The Audit Committee approved the selection of KPMG as the Company's independent registered public accounting firm for 2026. KPMG is currently the Company's independent registered public accounting firm.

Although the Company is not required to seek stockholder approval or ratification of this appointment, the Board believes that doing so is consistent with good corporate governance practices. If the appointment is not ratified, the Audit Committee will explore the reasons for stockholder rejection and will reconsider the appointment. Even if the appointment is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if the Audit Committee determines that such a change would be in the best interests of the Company and our stockholders.

We have been advised that a representative of KPMG will attend the Annual Meeting. Such representative will have an opportunity to make a statement if he or she desires to do so and will be available to respond to appropriate questions.

**THE BOARD OF DIRECTORS AND THE AUDIT COMMITTEE RECOMMEND A VOTE <u>FOR</u> RATIFICATION OF KPMG LLP AS THE COMPANY'S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2026.**

**PROPOSAL 4 –** Approval of Amended and Restated Certificate of Incorporation to Eliminate Supermajority Requirements

Our current certificate of incorporation, as amended to date, contains provisions requiring the affirmative vote of two-thirds of the outstanding stock of the Company entitled to vote to approve (collectively, the "Supermajority Voting Requirements"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Section 9**: the following transactions with an "Interested Person," meaning any entity or group, which owns five percent (5%) or more of any class of voting securities of the Company: (a) any merger or consolidation between the Company, or any of its subsidiaries, and an Interested Person; (b) any sale or other disposition of all or substantially all of the assets of the Company, or any of its subsidiaries, to an Interested Person; (c) any purchase or other acquisition by the Company, or any of its subsidiaries, of all or substantially all of the assets or stock of an Interested Person; and (d) any other transaction with an Interested Person which requires the approval of the stockholders of the Company under the General Corporation Law of Delaware, as in effect from time to time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Section 11**: an amendment to the Company's bylaws proposed by stockholders of the Company; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Section 13**: certain amendments to the Company's certificate of incorporation.

The Board periodically reviews the Company's governance policies, including the voting requirements under both the bylaws and its certificate of incorporation, against peers and best practice. In addition, we received a shareholder proposal requesting that the Board take each step necessary so that each voting requirement in our certificate of incorporation and bylaws that calls for a greater than simple majority vote be replaced by a requirement for majority of the votes cast for and against applicable proposals, or a simple majority in compliance with applicable laws. After carefully considering the advantages and disadvantages of maintaining the Supermajority Voting Requirements, in order to reinforce Insight's commitment to strong corporate governance practices and substantially implement the shareholder proposal, the Board has determined it is in the Company's best interest to eliminate the Supermajority Voting Requirements.

In order to eliminate the Supermajority Voting Requirements, the Board has approved, subject to stockholder approval, the adoption of the amended and restated certificate of incorporation in the form included in this proxy statement as Appendix B (the "Amended and Restated Certificate of Incorporation"), with the additions marked with bold, underlined text and deletions contemplated thereby indicated by strike-out text (collectively, the "Charter Amendments"). If approved by the Company's stockholders, the Charter Amendments would replace the Supermajority Voting Requirements with a voting standard that requires the affirmative vote of a majority of the

------

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

outstanding stock of the Company entitled to vote thereon. We believe the Amended and Restated Certificate of Incorporation compares favorably with, and substantially addresses, the essential objective of the received shareholder proposal.

The general description of the Amended and Restated Certificate of Incorporation, including the Charter Amendments, is qualified in its entirety by reference to the proposed Amended and Restated Certificate of Incorporation set forth in Appendix B. If approved by the Company's stockholders, the Amended and Restated Certificate of Incorporation will become effective upon filing with the Secretary of State of the State of Delaware, which we expect to file promptly following the Annual Meeting. If the Amended and Restated Certificate of Incorporation is not approved by the stockholders, the current certificate of incorporation will remain unchanged, and the provisions described above will remain in place.

**THE BOARD OF DIRECTORS RECOMMENDS A VOTE <u>FOR</u> THE APPROVAL OF THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO ELIMINATE SUPERMAJORITY VOTING REQUIREMENTS**

**AUDIT COMMITTEE REPORT**

The Company maintains an independent Audit Committee that operates under a written charter adopted by the Board of Directors. Each member of the Audit Committee is independent as defined in the listing standards of NASDAQ and under SEC rules and each of Mr. Allen and Ms. Breard has been designated as an "audit committee financial expert" by the Board of Directors.

Management has the responsibility for the Company's financial statements and overall financial reporting process, including the Company's internal controls. Management also is responsible for reporting on the effectiveness of the Company's internal controls over financial reporting. The Company's independent registered public accounting firm, KPMG, has the responsibility to conduct an independent audit in accordance with the standards of the Public Company Accounting Oversight Board (United States) (the "PCAOB") and to issue an opinion on whether or not the financial statements present fairly, in all material respects, the financial position of the Company and the results of its operations and its cash flows in conformity with U.S. generally accepted accounting principles. KPMG is also responsible for issuing an attestation report on the effectiveness of the Company's internal controls over financial reporting based upon its audit. The Audit Committee is directly responsible for the appointment, compensation, retention, and oversight of the independent auditors retained to audit our financial statements. The Audit Committee is responsible for the audit fee negotiations associated with our retention of KPMG. The members of the Audit Committee and the Board believe that the continued retention of KPMG to serve as our independent auditor is in our and our stockholders' best interest. KPMG has served as our independent registered public accounting firm since 1990.

The Audit Committee's responsibility is to monitor and oversee these processes. As part of its oversight responsibilities, the Audit Committee meets with the Company's Chief Financial Officer, Chief Accounting Officer, General Counsel, Vice President of Internal Audit and KPMG (with and without management present) to discuss the adequacy and effectiveness of the Company's internal controls and the quality of the financial reporting process.

Prior to the filing of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025 with the SEC, the Audit Committee:

• Reviewed and discussed with management the Company's audited consolidated financial statements included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2025 and considered management's view that the financial statements present fairly, in all material respects, the Company's financial condition and results of operations.

• Reviewed and discussed with management and KPMG the effectiveness of the Company's internal controls over financial reporting, including management's report and KPMG's attestation report on that topic.

• Discussed with KPMG the matters required to be discussed by the applicable requirements of the PCAOB and the SEC.

• Received the required written disclosures and the letter from KPMG required by applicable requirements of the PCAOB regarding KPMG's communications with the Audit Committee concerning independence. Based upon these communications, the Audit Committee discussed with KPMG its independence from the Company. In considering the independence of KPMG, the Audit Committee took into consideration the amount and nature of the fees paid to the firm for non-audit services, as described below.

------

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

In reliance on the review and discussions described above, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025, for filing with the SEC.

Respectfully submitted by the Audit Committee of the Board of Directors.

**Independent Registered Public Accounting Firm Fees and Independence**<br>

The Audit Committee reviews and approves the external auditor's engagement and audit plan, including fees, scope, staffing and timing of work. In addition, the Audit Committee Charter limits the types of non-audit services that may be provided by the independent auditors. Any permitted non-audit services to be performed by the independent auditors must be pre-approved by the Audit Committee after the committee is advised of the nature of the engagement and particular services to be provided. The Audit Committee pre-approved audit fees and all permitted non-audit services of the independent auditor in 2025. Responsibility for this pre-approval may be delegated to one or more members of the Audit Committee; all such approvals, however, must be disclosed to the Audit Committee at its next regularly scheduled meeting. The Audit Committee may not delegate authority for pre-approvals to management.

The following table presents fees paid or accrued for the audit of the Company's annual consolidated financial statements and all other professional services rendered by KPMG for the years ended December 31, 2025 and 2024.

---

| | | |
|:---|:---|:---|
| **KPMG Fees** | **Years Ended December 31** | **Years Ended December 31** |
| **KPMG Fees** | **2025** | **2024** |
| &nbsp;&nbsp;&nbsp;Audit fees | $3485000 | $3988000 |
| &nbsp;&nbsp;&nbsp;Audit-related fees | $430000 | $265000 |
| &nbsp;&nbsp;&nbsp;Tax fees | $203000 | $133000 |
| &nbsp;&nbsp;&nbsp;All other fees | $135000 | $55000 |
| &nbsp;&nbsp;&nbsp;**Total fees** | $4253000 | $4441000 |

---

*Audit Fees*. Consists principally of fees for professional services rendered for the audits of our consolidated financial statements, reviews of our consolidated financial statements included in our quarterly reports on Form 10-Q and statutory audits for foreign subsidiaries.

*Audit-Related Fees.* Consists principally of fees for services relating to due diligence assistance in connection with acquisitions.

*Tax Fees.* Consists principally of fees for services relating to tax compliance and tax planning and advice, including assistance with tax audits.

*All Other Fees*. Consists principally of fees for services related to a foreign subsidiary business review, a readiness assessment, and ongoing professional development and training resources.

The Audit Committee determined that the provision of services by KPMG described in the preceding paragraphs is compatible with maintaining KPMG's independence. All permissible non-audit services provided by KPMG in 2025 and 2024 described in the table above were pre-approved by the Audit Committee. In addition, no audit engagement hours were spent by people other than KPMG's employees, KPMG member firms located outside the United States and other third-party service providers operating under KPMG's supervision.

**FREQUENTLY ASKED QUESTIONS CONCERNING THE ANNUAL MEETING**

**Why did I receive these proxy materials?**

These proxy materials are first being distributed on or about April 2, 2026, to stockholders of the Company in connection with the solicitation by our Board of Directors of proxies to be voted at the Annual Meeting of Stockholders on May 13, 2026, at 8:30 a.m. MST, at Insight Enterprises, Inc., 2701 E. Insight Way Chandler, Arizona, 85286, and any postponement or adjournment thereof. This proxy statement describes the matters on which you, as a stockholder of the Company, are entitled to vote. It also includes information that we are required to provide to you under SEC rules and that is designed to assist you in voting your shares.

**What is the purpose of the Annual Meeting?**

At the Annual Meeting of Stockholders, stockholders will be asked to vote (1) to elect the 10 director nominees named in this proxy statement for a term expiring at the 2027 Annual Meeting of Stockholders (or until their respective successors have been duly elected and qualified), (2) to approve, on an advisory basis, the compensation of our Named Executive Officers, (3) to ratify the appointment of the Company's independent registered public accounting firm for the year ended December 31, 2026, and (4) to approve the Amended and Restated Certificate of Incorporation to eliminate Supermajority Voting Requirements. See the sections entitled "Proposal 1—Election of Directors," "Proposal 2—Advisory Vote to Approve Named Executive Officer Compensation," "Proposal 3—Ratification of Independent Registered Public Accounting Firm," and "Proposal 4—Approval of Amended and Restated Certificate of Incorporation to Eliminate Supermajority Voting Requirements." The Board of Directors does not know of any matters to be brought before the meeting other than as set forth in the Notice of Annual Meeting of Stockholders (the "Notice").

**Who can attend the Annual Meeting?**

Only holders of our common stock as of the close of business on the record date, which was March 16, 2026, or their duly appointed proxies, may attend the Annual Meeting. If you hold your shares through a broker, bank or other nominee, you will be required to show the notice or voting instructions form you received from your broker, bank or other nominee or a copy of a statement (such as a brokerage statement) from your broker, bank or other nominee reflecting your stock ownership as of March 16, 2026 in order to be admitted to the Annual Meeting. All attendees must bring a government-issued photo ID to gain admission to the Annual Meeting. Please note that recording devices, photographic equipment, large bags and packages will not be permitted in the meeting room.

**Who is entitled to vote at the Annual Meeting?**

Holders of our common stock as of the close of business on the record date, which was March 16, 2026, are entitled to notice of, and to vote at, the Annual Meeting. As of March 16, 2026, there were 30,078,270 shares of our common stock outstanding and entitled to vote at the Annual Meeting, with each share entitled to one vote.

**How do I vote at the Annual Meeting?**

Stockholders of record can vote in one of four ways:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **By telephone**—You may use the toll-free telephone number shown on your proxy card;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Via the Internet**—You may visit the Internet website indicated on your proxy card and follow the on-screen instructions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **By mail**—You may date, sign and promptly return your proxy card by mail in a postage prepaid envelope; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **In person**—You may deliver a completed proxy card at the meeting or vote in person.

------

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

Voting instructions for stockholders of record (including instructions for both telephonic and Internet voting) are provided under the heading "Voting Information" of this proxy statement and on the proxy card. The telephone and Internet voting procedures are designed to authenticate stockholder identities, to allow stockholders to give voting instructions and to confirm that stockholders' instructions have been recorded properly. A control number, located on the proxy card, will identify stockholders and allow them to submit their proxies and confirm that their voting instructions have been properly recorded. Costs associated with telephone and electronic access, such as usage charges from telephone companies and Internet access providers, must be borne by the stockholder. If you submit your proxy by telephone or via the Internet, it will not be necessary to return your proxy card. The deadline for voting by telephone or via the Internet is 11:59 p.m. ET on Tuesday, May 12, 2026.

If your shares are held through a broker, bank or other nominee, please follow the voting instructions on the form you receive from such institution. In such situations, the availability of telephone and Internet voting will depend on your institution's voting procedures. If you wish to vote in person at the Annual Meeting, you must first obtain a legal proxy issued in your name from the institution that holds your shares.

**What if I do not vote or do not indicate how my shares should be voted on my proxy card?**

If a stockholder of record does not return a signed proxy card or submit a proxy by telephone or via the Internet and does not attend the meeting and vote in person, his or her shares will not be voted. Shares of our common stock represented by properly executed proxies received by us or proxies submitted by telephone or via the Internet, which are not revoked, will be voted at the meeting in accordance with the instructions contained therein.

**If you submit a properly completed proxy but do not indicate how your shares should be voted on a proposal, the shares represented by your proxy will be voted as the Board of Directors recommends on such proposal.**

**What if my shares of the Company's common stock are held for me by a broker?**

If you are the beneficial owner of shares held for you by a broker, your broker must vote those shares in accordance with your instructions. A "broker non-vote" occurs when a broker or other nominee holding shares for a beneficial owner does not vote on a particular proposal because the broker or other nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner.

• **Non-Discretionary Items.** The election of directors (Proposal 1), the advisory vote to approve Named Executive Officer compensation (Proposal 2), and the amendment and restatement of our certificate of incorporation (Proposal 4) may not be voted on by your broker if it has not received voting instructions.

• **Discretionary Items.** The ratification of KPMG LLP as the Company's independent registered public accounting firm (Proposal 3) is a discretionary item. Generally, brokers that do not receive voting instructions from beneficial owners may vote on this proposal in their discretion.

**How can I change my votes or revoke my proxy after I have voted?**

Any proxy signed and returned by a stockholder or submitted by telephone or via the Internet may be revoked or changed at any time before it is exercised at the Annual Meeting or any adjournments or postponements thereof by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Mailing written notice of revocation or change to our Corporate Secretary at Insight Enterprises, Inc., 2701 E. Insight Way, Chandler, Arizona 85286;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Delivering a later-dated proxy (either in writing, by telephone or via the Internet); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Voting in person at the meeting.

Attendance at the meeting will not, in and of itself, constitute revocation of a proxy.

------

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

**Will my votes be publicly disclosed?**

No. As a matter of policy, stockholder proxies, ballots and tabulations that identify individual stockholders are not publicly disclosed and are available only to the inspector of election and certain employees, who are obligated to keep such information confidential.

**Who will count the votes?**

A representative of the Company will serve as the inspector of election for the Annual Meeting and will count the votes.

**What if other matters come up during the Annual Meeting?**

If any other matters properly come before the meeting, including a question of adjourning or postponing the meeting, the persons named in the proxies or their substitutes acting thereunder will have discretion to vote on such matters in accordance with their best judgment.

**What constitutes a quorum at the Annual Meeting?**

The presence at the Annual Meeting of Stockholders, in person or represented by proxy, of the holders of a majority in voting power of the outstanding capital stock entitled to vote at the Annual Meeting is required to constitute a quorum to transact business at the Annual Meeting. Abstentions and broker non-votes will be counted toward the establishment of a quorum.

**How many votes are required to approve each matter to be considered at the Annual Meeting?**

**Proposal 1: Election of director nominees named in this proxy statement.** Each of the 10 nominees for director will be elected upon the affirmative vote of the majority of votes cast with respect to the director's election, which means the number of votes cast "for" a director nominee must exceed the number of votes cast "against" that director nominee. Any incumbent director nominee who is not elected by a majority of votes cast must tender his or her resignation to the Board, and the Nominating and Governance Committee will make a recommendation to the Board on whether to accept or reject the resignation, or whether other action should be taken. In such a situation, the Board will act on the Nominating and Governance Committee's recommendation and publicly disclose its decision and the rationale behind its decision within 90 days from the date of the certification of the election results. In the event of a contested election, director nominees who receive the most votes for the number of seats up for election will be elected. Broker non-votes and abstentions will have no effect on the proposal.

**Proposal 2: Advisory vote to approve named executive officer compensation.** The affirmative vote of the holders of a majority of the shares entitled to vote on the proposal, present in person or represented by proxy at the Annual Meeting is required to approve, on an advisory, non-binding basis, the compensation paid to our Named Executive Officers. Abstentions will be counted as present and entitled to vote on the proposal and will therefore have the effect of a vote against the proposal. Broker non-votes will not be counted as present and entitled to vote on the proposal and will therefore have no effect on the outcome of the proposal.

**Proposal 3: Ratification of KPMG LLP as the Company's independent registered public accounting firm.** The affirmative vote of the holders of a majority of the shares entitled to vote on the proposal, present in person or represented by proxy at the Annual Meeting is required to ratify KPMG LLP as the Company's independent registered public accounting firm for 2026. Abstentions will be counted as present and entitled to vote on the proposal and will therefore have the effect of a vote against the proposal. Because brokers can vote on this proposal in their discretion without instructions from beneficial stockholders, there is not expected to be any broker non-votes on this proposal.

------

<u>[**Table of Contents**](#i1161954e358c444694fd6e2f12f10639_16)</u>

**Proposal 4: Approval of the Amended and Restated Certificate of Incorporation to eliminate Supermajority Voting Requirements.** The affirmative vote of the holders of at least a majority of the outstanding shares is required to approve the Amended and Restated Certificate of Incorporation to eliminate Supermajority Voting Requirements. Abstentions and broker non-votes will therefore have the effect of a vote against the proposal.

**Who pays to prepare, mail and solicit the proxies?**

We will bear the costs of solicitation of proxies for the Annual Meeting of Stockholders, including preparation, assembly, printing and mailing of the Notice, this proxy statement, the Annual Report for the year ended December 31, 2025, the proxy card and any additional information furnished to stockholders. We may reimburse persons representing beneficial owners of common stock for their costs of forwarding any solicitation materials to such beneficial owners. Proxies may be solicited in person or by mail, telephone or electronic transmission on our behalf by our directors, officers or employees. However, we do not reimburse or pay additional compensation to our own directors, officers or other employees for soliciting proxies. In addition, we have retained Okapi Partners LLP to assist us in the distribution and solicitation of proxies. We estimate that we will pay Okapi Partners LLP approximately $13,500, plus reimbursement of out-of-pocket expenses, for its services.

**OTHER BUSINESS**

The Board of Directors has no knowledge of any other matter to be submitted at the Annual Meeting. If any other matter shall properly come before the Annual Meeting, including a question of adjourning or postponing the meeting, the persons named in the proxy card or their substitutes acting thereunder will have discretionary authority to vote the shares thereby represented in accordance with their best judgment.

**Annual Report on Form 10-K**

A copy of our Annual Report on Form 10-K for the year ended December 31, 2025 is being furnished to stockholders concurrently herewith. Insight will mail without charge, upon written request, another copy of our Annual Report on Form 10-K for the year ended December 31, 2025, including the consolidated financial statements and list of exhibits, and any particular exhibit specifically requested. Requests should be addressed to our Corporate Secretary at 2701 E. Insight Way, Chandler, Arizona 85286.

**USE OF NON-GAAP FINANCIAL MEASURES**

The non-GAAP financial measures (referred to in this proxy statement as Adjusted EFO, Adjusted Diluted EPS and Adjusted ROIC) exclude the items noted above. Other consists of data center service outage related expenses, net of recoveries and certain acquisition and integration-related expenses, as applicable. The Company excludes these items when internally evaluating its results of operations. These non-GAAP measures are used by management to evaluate financial performance against budgeted amounts, to calculate incentive compensation, to assist in forecasting future performance and to compare the Company's results to those of the Company's competitors. The Company believes that these non-GAAP financial measures are useful to investors because they allow for greater transparency, facilitate comparisons to prior periods and the Company's competitors' results and assist in forecasting performance for future periods. These non-GAAP financial measures are not prepared in accordance with GAAP and may be different from non-GAAP financial measures presented by other companies. Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.
