PROXY STATEMENT

GENERAL INFORMATION

This Proxy Statement is being furnished in connection with the solicitation of proxies by the Board of Directors (the "Board") of OSI Systems, Inc. (the "Company") for use at our Annual Meeting of Stockholders ("Annual Meeting"), to be held at 10:00 a.m., Pacific Time on December 10, 2018, at our offices at 12525 Chadron Avenue, Hawthorne, California 90250, and at any adjournment thereof.

We are making our proxy materials, which include the Notice of Annual Meeting of Stockholders, Proxy Statement, Proxy Card and our most recent Annual Report on Form 10-K ("Proxy Materials"), available to our stockholders via the Internet, although registered stockholders and those stockholders who have previously requested to receive printed copies instead will receive their Proxy Materials in the mail. We anticipate that the Notice of Internet Availability of Proxy Materials will be mailed on or about October 25, 2018.

Stockholders of record as of the close of business on October 17, 2018 will receive a Notice of Internet Availability of Proxy Materials. The Notice of Internet Availability of Proxy Materials contains instructions about how to access the Proxy Materials and vote via the Internet without attending the Annual Meeting. If you receive a Notice of Internet Availability of Proxy Materials but would instead prefer to receive a printed copy of the Proxy Materials rather than downloading them from the Internet, you may do so by following the instructions for requesting such materials included in the Notice of Internet Availability of Proxy Materials.

If you are a stockholder that receives a printed copy of the Proxy Materials by mail, you may view the Proxy Materials on the Internet at http://www.proxyvote.com . However, in order to direct your vote without attending the Annual Meeting you must complete and mail the Proxy Card or voting instruction card enclosed (postage pre-paid return envelope also enclosed) or, if indicated on the Proxy Card that you receive, by telephone or Internet voting. Please refer to the Proxy Card that you receive for instructions.

When a proxy is properly submitted, the shares it represents will be voted in accordance with any directions noted thereon. Any stockholder giving a proxy has the power to revoke it at any time before it is voted by written notice to the Secretary of the Company by issuance of a subsequent proxy as more fully described on the Proxy Card. In addition, a stockholder attending the Annual Meeting may revoke his or her proxy and vote in person if he or she desires to do so, but attendance at the Annual Meeting will not of itself revoke the proxy.

At the close of business on October 17, 2018, the record date for determining stockholders entitled to notice of and to vote at the Annual Meeting, we had issued and outstanding 18,153,122 shares of common stock, $0.001 par value ("Common Stock"). A majority of the shares issued and outstanding on the record date, present in person at the Annual Meeting or represented at the Annual Meeting by proxy, will constitute a quorum for the transaction of business. Shares that are voted with respect to any proposal are treated as being present at the Annual Meeting for purposes of establishing a quorum. Each share of Common Stock entitles the holder of record thereof to one vote on any matter coming before the Annual Meeting.

A Proxy Card, when properly submitted via the Internet, telephone or mail, also confers discretionary authority with respect to amendments or variations to the matters identified in the Notice of Annual Meeting of Stockholders and with respect to other matters which may be properly brought before the

Table of Contents

Annual Meeting. At the time of printing this Proxy Statement, our management was not aware of any other matters to be presented for action at the Annual Meeting. If, however, other matters which are not now known to management should properly come before the Annual Meeting, the proxies hereby solicited will be exercised on such matters in accordance with the best judgment of the proxy holders.

Abstentions and broker non-votes represented by submitted proxies will be included in the calculation of the number of the shares present at the Annual Meeting for the purposes of determining a quorum. "Broker non-votes" means shares held of record by a broker that are not voted because the broker has not received voting instructions from the beneficial owner of the shares and either lacks or declines to exercise the authority to vote the shares in its discretion.

Proposal One. In accordance with our Bylaws, directors are elected by a plurality of the votes cast, and the nominees who receive the most votes will be elected. Proposal One is considered a "non routine" matter and, accordingly, brokerage firms and nominees do not have the authority to vote their clients' unvoted shares on Proposal One or to vote their clients' shares if the clients have not furnished voting instructions within a specified period of time prior to the Annual Meeting. Abstentions and broker non-votes will not be counted as votes cast and will have no effect on the outcome of the vote on Proposal One. Votes marked "withhold" will not affect the outcome of the election of directors.

Proposal Two. In accordance with our Bylaws, to be approved, the ratification of Moss Adams LLP as our independent registered accounting firm must receive the affirmative vote of the majority of the shares of Common Stock present in person or by proxy and cast at the Annual Meeting. Proposal Two is considered a "routine" matter and, accordingly, brokerage firms and nominees have the authority to vote their clients' unvoted shares on Proposal Two as well as to vote their clients' shares if the clients have not furnished voting instructions within a specified period of time prior to the Annual Meeting. Abstentions and broker non-votes will not be counted as votes cast and will have no effect on the outcome of the vote on Proposal Two.

Proposal Three. In accordance with our Bylaws, to be approved, the proposal regarding our executive compensation for the fiscal year ended June 30, 2018 must receive the affirmative vote of the majority of the shares of Common Stock present in person or by proxy and cast at the Annual Meeting. Proposal Three is considered a "non-routine" matter and, accordingly, brokerage firms and nominees do not have the authority to vote their clients' unvoted shares on Proposal Three or to vote their clients' shares if the clients have not furnished voting instructions within a specified period of time prior to the Annual Meeting. Abstentions and broker non-votes will not be counted as votes cast and will have no effect on the outcome of the vote on Proposal Three. The vote on Proposal Three is advisory and therefore not binding on the Company, the Compensation and Benefits Committee (the "Compensation Committee") or the Board. Although non-binding, the Board values the opinions that our stockholders express in their votes, and the votes will provide information to the Compensation Committee regarding investor sentiment about our executive compensation philosophy, policies and practices, which the Compensation Committee will be able to consider when determining executive compensation in the future.

All stockholders entitled to vote at the Annual Meeting will receive either the Notice of Internet Availability of Proxy Materials or a printed copy of the Proxy Materials. We will pay the expenses of soliciting proxies for the Annual Meeting, including the cost of preparing, assembling, posting on the Internet and mailing the Notice of Internet Availability of Proxy Materials and the Proxy Materials. Proxies may be solicited personally, by mail, by e-mail, over the Internet, or by telephone, by directors, officers and regular employees of the Company who will not be additionally compensated therefore.

The matters to be considered and acted upon at the Annual Meeting are more fully discussed below.

Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Stockholders to be held on December 10, 2018: The Proxy Notice, this Proxy Statement and Annual Report on Form 10-K for the fiscal year ended June 30, 2018 are available at http://www.proxyvote.com .

ELECTION OF DIRECTORS
(Proposal No. 1 of the Proxy Card)

Nominees

Our Board consists of seven members. At each annual meeting of stockholders, directors are elected for a term of one year to succeed those directors whose terms expire on the annual meeting date.

The seven candidates nominated for election as directors at the Annual Meeting are Deepak Chopra, Ajay Mehra, Steven C. Good, Meyer Luskin, William F. Ballhaus, James B. Hawkins, and Gerald Chizever. All of our director nominees are currently directors of the Company and were previously elected to serve on the Board by our stockholders.

The enclosed Proxy will be voted in favor of these individuals unless other instructions are given. If elected, the nominees will serve as directors until our next annual meeting of stockholders, and until their successors are elected and qualified. If any nominee declines to serve or becomes unavailable for any reason, or if a vacancy occurs before the election (although we know of no reason to anticipate that this will occur), the proxies may be voted for such substitute nominees as the Board may designate.

If a quorum is present and voting, the seven nominees for directors receiving the highest number of votes will be elected as directors. Abstentions and shares held by brokers that are present, but not voted because the brokers were prohibited from exercising discretionary authority (broker non-votes) will be counted as present only for purposes of determining if a quorum is present.

The current directors and nominees for election as directors at this meeting are as follows:

Relationships Among Directors or Executive Officers

There are no arrangements or understandings known to us between any of the directors or nominees for director and any other person pursuant to which any such person was or is to be elected a director.

Ajay Mehra is the first cousin of Deepak Chopra. Other than this relationship, there are no family relationships among our directors or Named Executive Officers (as defined in "Compensation of Executive Officers and Directors – Summary Compensation Table").

Board Role in Risk Oversight

Our Board is responsible for our risk oversight. Risks we face include competitive, economic, operational, financial, accounting, liquidity, tax, regulatory, foreign country, safety, employment, political, and other risks. Risks are reported to our Board through our executive officers, who are responsible for the identification, assessment, and management of our risks. Our Board regularly discusses the risks reported by our executive officers and reviews with management strategies and actions to mitigate the risks and the status and effectiveness of such strategies and actions.

To optimize its risk oversight capabilities and efficiently oversee our risks, the Board delegates to its committees oversight responsibility for particular areas of risk. For example, the Audit Committee oversees management of major financial risks, including risks related to accounting, auditing, financial reporting, and maintaining effective internal control over financial reporting. The Risk Management Committee oversees management of key enterprise risks, including strategic, operational, legal, regulatory,

Table of Contents

and compliance. The Nominating and Governance Committee oversees risks related to the effectiveness of the Board. The Compensation Committee oversees risks related to our executive compensation policies and practices. The Technology Committee oversees risks related to technology matters.

Board Leadership Structure and Lead Independent Director

Our Chairman of the Board is our Chief Executive Officer. We believe that currently combining the positions of Chief Executive Officer and Chairman serves as an effective link between management's role of identifying, assessing and managing risks and the Board's role of risk oversight. Mr. Chopra possesses in-depth knowledge of the issues, opportunities and challenges we face and is thus well positioned to develop agendas and highlight issues that ensure that the Board's time and attention are focused on the most critical matters. In addition, our Board has determined that this leadership structure is optimal because it believes that having one leader serving as both the Chairman and Chief Executive Officer provides decisive, consistent and effective leadership, as well as clear accountability. Having one person serve as Chairman and Chief Executive Officer also enhances our ability to communicate our message and strategy clearly and consistently to our stockholders, employees, and other companies with which we do business. Although we believe that the combination of the Chairman and Chief Executive Officer roles is appropriate under current circumstances, we will continue to review this issue periodically to determine whether, based on the relevant facts and circumstances, separation of these offices would serve our best interests and the best interests of our stockholders.

The combined Chairman of the Board and Chief Executive Officer position is balanced by the number of independent directors serving on our Board, our independent committees and our lead independent director. Meyer Luskin is currently our lead independent director and brings to this role considerable skills and experience as described above in "Election of Directors." The role of lead independent director is designed to further promote the independence of our Board and appropriate oversight of management and to facilitate free and open discussion and communication among our independent directors.

Board Meetings, Independence and Committees of the Board

There were 12 meetings of the Board and the Board acted pursuant to unanimous written consent on two additional occasions during the fiscal year ended June 30, 2018. During fiscal 2018, the Board had a standing Audit Committee, Compensation Committee, Nominating and Governance Committee, Risk Management Committee, and Technology Committee. The members of each committee are appointed by the majority vote of the Board. All persons serving as a director during the fiscal year ended June 30, 2018 attended more than 75% of the aggregate number of meetings held by the Board and all committees on which such director served.

The Board has determined that each of the nominees for director, except Mr. Chopra and Mr. Mehra, is independent within the meaning of the director independence standards of The NASDAQ Stock Market (the "Listing Standards"), as currently in effect. Furthermore, the Board has determined that each of the members of each of the committees of the Board is independent within the meaning of the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") and the Listing Standards, as applicable and currently in effect.

Audit Committee

We have a separately designated, standing Audit Committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The Audit Committee makes recommendations for selection of our independent public accountants, reviews with the independent public accountants the plans and results of the audit engagement, approves professional services provided by the independent public accountants, reviews the independence of the independent public accountants, considers the range of audit and any non-audit fees, and reviews our financial

Table of Contents

statements and the adequacy of our internal accounting controls and financial management practices. All members of the Audit Committee are independent, as independence for audit committee members is defined in Rule 10A-3(b)(1) under the Exchange Act and the Listing Standards applicable to our Company.

The Audit Committee currently consists of four independent directors – Messrs. Good, Luskin and Hawkins and Dr. Ballhaus. The Board has determined that, based upon his work experience, Mr. Good qualifies as an "Audit Committee Financial Expert" as this term has been defined under the rules and regulations of the SEC. Information regarding Mr. Good's work experience is set forth above under "Election of Directors." To date, no determination has been made as to whether the other members of the Audit Committee also qualify as Audit Committee Financial Experts.

There were four meetings of the Audit Committee during the fiscal year ended June 30, 2018. See "Report of Audit Committee." The Audit Committee acts pursuant to a written charter adopted by the Board, a copy of which is available under the Investor Relations section of our website – http://www.osi-systems.com .

Risk Management Committee

The Risk Management Committee is responsible for overseeing and monitoring our key enterprise risks, including strategic, operational, legal, regulatory, compliance, security, and reputational risks. The Risk Management Committee has responsibility for reviewing our compliance program and our major legal compliance risk exposures, monitoring our code of ethics, reviewing our risk management reviews and assessments, and regularly assessing the continuing appropriateness of a succession plan for our Chief Executive Officer and other executive officers. The Risk Management Committee currently consists of four independent directors – Messrs. Chizever, Good, and Luskin and Dr. Ballhaus. There were three meetings of the Risk Management Committee during the fiscal year ended June 30, 2018.

The Risk Management Committee acts pursuant to a written charter adopted by the Board, a copy of which is available under the Investor Relations section of our website – http://www.osi-systems.com .

Compensation Committee

The Compensation Committee is responsible for determining compensation and benefits for our executive officers, reviewing and approving executive compensation policies and practices, and providing advice and input to the Board in the administration of our equity compensation and benefits plans. The Compensation Committee engages and consults with independent compensation consultants in the performance of its duties. The Compensation Committee currently consists of three independent directors – Messrs. Luskin and Good and Dr. Ballhaus. There were 13 meetings of the Compensation Committee during the fiscal year ended June 30, 2018. See "Compensation Committee Report."

The Compensation Committee acts pursuant to a written charter adopted by the Board, a copy of which is available under the Investor Relations section of our website – http://www.osi-systems.com.

Nominating and Governance Committee

The Nominating and Governance Committee is responsible for evaluating nominations for new members of the Board. The Nominating and Governance Committee currently consists of two independent directors – Dr. Ballhaus and Mr. Hawkins. There was one meeting of the Nominating and Governance Committee during the fiscal year ended June 30, 2018.

The Nominating and Governance Committee will consider director candidates based upon their business and financial experience, personal characteristics, expertise that is complementary to the background and experience of other Board members, willingness to devote the required amount of time to carrying out the duties and responsibilities of membership on the Board, willingness to objectively appraise

Table of Contents

management performance, and any such other qualifications the Nominating and Governance Committee deems necessary to ascertain the candidate's ability to serve on the Board.

The Nominating and Governance Committee has sought to identify director nominees that have diverse professional and educational backgrounds that are believed to complement the skills offered by existing Board members. The Nominating and Governance Committee acts pursuant to a written charter adopted by the Board, a copy of which is available under the Investor Relations section of our website – http://www.osi-systems.com .

Technology Committee

The Technology Committee is responsible for evaluating and making recommendations to the Board regarding all technology-based matters. The Technology Committee currently consists of three independent directors – Dr. Ballhaus and Messrs. Hawkins and Chizever. There was one meeting of the Technology Committee during the fiscal year ended June 30, 2018.

The Technology Committee acts pursuant to a written charter adopted by the Board, a copy of which is available under the Investor Relations section of our website – http://www.osi-systems.com.

Director Nomination Process

The Nominating and Governance Committee will consider director candidates recommended by stockholders. Stockholders who wish to submit names of candidates for election to the Board must do so in writing. The recommendation should be sent to the following address: c/o Secretary, OSI Systems, Inc., 12525 Chadron Avenue, Hawthorne, CA 90250. Our Secretary will, in turn, forward the recommendation to the Nominating and Governance Committee. The recommendation should include the following information:

In performing its evaluation and review, the Nominating and Governance Committee generally does not differentiate between candidates proposed by stockholders and other proposed nominees, except that the Nominating and Governance Committee may consider, as one of the factors in its evaluation of stockholder recommended candidates, the size and duration of the interest of the recommending stockholder or stockholder group in the equity of the Company.

During the fiscal year ended June 30, 2018, no member of our Compensation Committee had any relationship or transaction with our Company required to be disclosed pursuant to Item 404 of Regulation S-K.

The Board recommends that you vote "FOR" the election of each of Deepak Chopra, Ajay Mehra, Steven C. Good, Meyer Luskin, William F. Ballhaus, Jr., James B. Hawkins, and Gerald Chizever as our directors. Holders of proxies solicited by this Proxy Statement will vote the proxies received by them as directed on the Proxy or, if no direction is made, for each of the above-named nominees. The election of directors requires a plurality of the votes cast at the Annual Meeting.

RATIFICATION OF SELECTION OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
(Proposal No. 2 of the Proxy Card)

The Audit Committee has selected Moss Adams LLP ("Moss Adams") as our independent registered public accountants for the year ending June 30, 2019 and has further directed that management submit the selection of independent registered public accountants for ratification by our stockholders at the Annual Meeting. Moss Adams has no financial interest in the Company, and neither it nor any member or employee of the firm has had any connection with the Company in the capacity of promoter, underwriter, voting trustee, director, officer or employee.

In the event that our stockholders fail to ratify the selection of Moss Adams, the Audit Committee will reconsider whether or not to retain the firm. Even if the selection is ratified, the Audit Committee and the Board in their discretion may direct the appointment of a different independent accounting firm at any time during the year if they determine that such a change would be in our and our stockholders' best interests.

Representatives of Moss Adams are expected to be present at the Annual Meeting, and they will have an opportunity to make a statement if they so desire and are expected to be available to respond to appropriate questions.

The Board recommends a vote "FOR" the ratification of Moss Adams as our independent registered public accountants for the fiscal year ending June 30, 2019. Holders of proxies solicited by this Proxy Statement will vote the proxies received by them as directed on the Proxy or, if no direction is made, in favor of this proposal. In order to be adopted, this proposal must be approved by the affirmative vote of a majority of the shares of Common Stock present in person or by proxy and cast at the Annual Meeting.

ADVISORY VOTE ON THE COMPANY'S EXECUTIVE COMPENSATION
FOR THE FISCAL YEAR ENDED JUNE 30, 2018
(Proposal No. 3 of the Proxy Card)

Background

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd Frank Act") enables our stockholders to vote to approve, on an advisory, non-binding basis, our executive compensation for the fiscal year ended June 30, 2018 as disclosed in the Proxy Statement in accordance with the SEC's rules, including Section 14A of the Exchange Act ("Say-on-Pay"). We currently conduct this advisory vote on an annual basis, and the next advisory vote is expected to be conducted at our 2019 Annual Meeting of Stockholders.

Summary

Our Board is committed to excellence in governance and is aware of the significant interest in executive compensation matters by investors and the general public. We are asking our stockholders to provide advisory approval of our executive compensation as such compensation is described in the "Compensation Discussion and Analysis" section, the tabular disclosure regarding such compensation, and the accompanying narrative disclosure set forth in the Proxy Statement. We recognize and value the critical role that executive leadership plays in our performance. Our executive compensation philosophy is intended to ensure that executive compensation is aligned with our short- and long-term business strategy, objectives, and stockholder interests. Our executive compensation is designed to attract, motivate, and retain highly qualified executives. We believe that our compensation policies and procedures are centered on pay-for-performance principles and are strongly aligned with the short- and long-term interests of our stockholders.

We urge you to review the "Compensation Discussion and Analysis" section of the Proxy Statement and executive-related compensation tables for more information.

Emphasis on Pay-For-Performance Principles

We believe that executive compensation should be tied to our performance on both a short-term and long-term basis. We believe that our continued success is closely tied to the performance of our executive officers and have designed our compensation practices in order to reward the executives for their contributions to our overall success.

Alignment with Stockholders' Interests

We grant annual incentives based in part on each executive's contribution to enhancing our short- and long-term profitable growth. We also grant long-term equity-based incentives as a substantial component of the compensation program to reward long-term performance and further align the interests of management with those of our stockholders. In recent years, we have generally used restricted stock units as our equity incentive vehicle as these awards enable the executives to establish a meaningful equity stake in our Company while allowing them to participate in future value creation through appreciation of the shares. These awards tie the executives' interests to those of long-term stockholders and serve to motivate the executives to lead us to achieve long-term financial goals that are expected to lead to increased stockholder value. In addition to linking compensation value to stockholder value, these awards generally have vesting conditions, which creates a strong retention incentive and helps ensure the continuity of our operations. For fiscal year 2018, 100% of the long-term equity incentives granted to our corporate Named Executive Officers (our CEO, CFO, and General Counsel) and a significant portion of our equity incentives granted to our divisional Named Executive Officers consisted of restricted stock units subject to performance vesting based on growth of adjusted EBITDA per share.

Table of Contents

Long-Term Performance

In order to promote our philosophy of pay-for-performance and furthering our objective of aligning the interests of management with those of our stockholders, we have established performance programs for certain of our executive officers. These programs focus on the achievement of our long-term financial goals and factors that create long-term stockholder value. By establishing performance targets tied to key corporate financial metrics, we are incentivizing our officers to achieve our long-term corporate objectives and ultimately increase stockholder value.

Highlights of 2018 Executive Compensation Program

The Board believes our executive compensation program is designed appropriately and that a vote in favor of the proposal is warranted, including for these reasons: (1) 100% of corporate Named Executive Officer equity awards for fiscal 2018 were performance-based and tied to measurable pre-established targets; (2) we are committed to having strong governance standards and continue to take steps to further this commitment; and (3) we value the opinions and feedback we receive from, and we continue to engage with, our stockholders, and our executive compensation program directly reflects our stockholders' input.

1. 100% Performance-Based Equity Awards for Corporate Named Executive Officers: Equity awards granted to our CEO, CFO, and General Counsel are 100% performance-based and tied to measurable pre-established adjusted EBITDA per share goals.

100% of the equity grants made to our corporate Named Executive Officers and a significant portion of the equity grants made to our divisional Named Executive Officers during fiscal 2018 were performance-based and tied to pre-established adjusted EBITDA per share targets which require significant annual growth. 40% of the maximum number of shares that can be earned under each Named Executive Officer's 2018 award has a three-year performance component which vests or is forfeited following the end of the three-year performance cycle, subject to the achievement of the adjusted EBITDA per share growth target for fiscal 2020. If at least 85% of this three-year adjusted EBITDA per share target is not attained, then these shares are forfeited. The remaining 60% of the maximum number of shares that can be earned under each executive's 2018 award may vest up to 20% per year over the three-year period if annual adjusted EBITDA per share growth targets are exceeded for fiscal years 2018, 2019 and 2020, respectively.

We believe that the performance targets underlying our long-term equity incentive program are rigorous, and we have not disclosed current targets because their disclosure would allow our competitors to determine the EBITDA and pricing related to key programs, which would be competitively harmful to us.

The adjusted EBITDA per share target for the three-year performance cycle ended in fiscal 2018 was $6.00 and was achieved at 171% of target. As a result the 60,000 shares granted to our CEO in fiscal 2016 were vested. In addition, our CEO earned 92,015 shares, consisting of 26,480 vested shares earned pursuant to the fiscal 2018 grant, 35,535 vested shares earned pursuant to the fiscal 2017 grant and 30,000 vested shares earned pursuant to the fiscal 2016 grant.

2. Corporate Governance and Best Practices: We are committed to having strong governance standards with respect to our compensation programs, procedures, and practices.

We have taken the following actions to enhance our corporate governance and executive compensation policies:

•: Appointed a lead independent director to further promote the independence of our Board and appropriate oversight of management and to facilitate free and open discussion and communication among our independent directors.
•: Prohibited all hedging and pledging of our stock by executive officers and directors. As of the date of the Proxy Statement, no shares of our stock are pledged by any Named Executive Officer or director.

Table of Contents

•: Adopted a robust clawback policy that provides that if an accounting restatement is required due to material non-compliance with any accounting requirements, then we will seek to recover any excess in the incentive compensation earned by all of our executive officers, regardless of whether they were at fault or not in the circumstances leading to the restatement, over the prior three years over what they would have earned if there had not been a material restatement of the financial statements. We have also included clawback provisions in each Named Executive Officer's employment agreement.
•: Established rigorous Company stock ownership guidelines requiring each executive officer to own Company stock valued at least at five times his annual base salary. These guidelines align the executives' long-term interests with those of our stockholders. In addition, prior to attaining the 5X share ownership guideline, each executive is required to retain at least 50% of the shares acquired upon exercise of options or vesting of restricted stock or unit awards, net of amounts required to pay taxes and exercise price.

3. Communications with Stockholders: We maintain open lines of communication with our stockholders. Based on feedback we received from stockholders about our compensation programs, we revised our annual cash incentive program to directly address stockholder input.

Our Compensation Committee takes very seriously stockholder feedback with respect to executive compensation. We previously conducted a robust stockholder outreach and continue to have open lines of communications with our stockholders, and our senior management routinely interacts with our stockholders on a variety of matters, including our executive compensation programs and practices.

In response to the specific stockholder feedback we received, our Compensation Committee revised our annual cash executive officer incentive program to be performance-based and formulaically tied to measurable thresholds, targets, and maximums. At our 2017 annual meeting, approximately 98% of the votes cast on the advisory vote on the compensation of our Named Executive Officers were in favor of our executive compensation. Considering this overwhelming majority in favor, our Compensation Committee determined to continue to apply the same approach with respect to compensation policies and decisions for fiscal 2018.

Our Board believes that the information above as well as that provided in the section entitled "Compensation of Executive Officers and Directors" contained in the Proxy Statement demonstrates that our executive compensation program was designed appropriately and is working to ensure that management's interests are aligned with the stockholders' interests and support long-term value creation. The following resolution will be submitted for a stockholder vote at the Annual Meeting:

"RESOLVED, that the stockholders of OSI Systems, Inc. approve, on an advisory basis, the compensation of the Company's Named Executive Officers, as disclosed pursuant to Item 402 of Regulation S-K of the SEC, including in the section entitled "Compensation Discussion and Analysis," the accompanying compensation tables, and the related narrative disclosure contained in the Proxy Statement."

The Board recommends that you vote "FOR" the approval of our executive compensation for the fiscal year ended June 30, 2018. Holders of proxies solicited by this Proxy Statement will vote the proxies received by them as directed on the Proxy or, if no direction is made, in favor of this proposal. In order to be approved on an advisory basis, this proposal must be approved by the affirmative vote of a majority of the shares of Common Stock present in person or by proxy and cast at the Annual Meeting.

Compensation Discussion and Analysis

This Compensation Discussion and Analysis describes our compensation philosophy, objectives, and processes, including the methodology for determining executive compensation for our Named Executive Officers. For additional information, please refer to the more detailed compensation disclosures beginning with and following the "Summary Compensation Table" contained in this Proxy Statement.

Advisory Vote on Named Executive Officer Compensation

We maintain open lines of communication with our stockholders, and senior management routinely interacts with our stockholders on a number of matters, including executive compensation, in order to better understand their opinions and to obtain their feedback. Further, the Compensation Committee considers the outcome of our annual say on pay vote when making decisions regarding our executive compensation program. At our 2017 annual meeting, approximately 98% of the votes cast on the advisory vote on the compensation of our Named Executive Officers were in favor of our executive compensation policies. Considering the level of support of our stockholders of our compensation program, our Compensation Committee determined to continue to apply the same approach with respect to compensation policies and decisions for fiscal 2018.

At the upcoming Annual Meeting, we will again hold an annual advisory vote to approve executive compensation. We will continue to engage with our stockholders throughout the year, and the Compensation Committee will consider the results from this year's and future advisory votes on executive compensation, as well as any feedback received from stockholders.

Executive Compensation Summary

Fiscal 2018 Performance

During fiscal 2018, we (a) achieved record revenue of $1.089 billion representing 13% growth as compared to fiscal 2017; (b) delivered 21% non-GAAP earnings per share growth compared to the prior fiscal year; (c) achieved outstanding operating cash flow of $133 miilion representing 112% growth as compared to fiscal 2017; (d) had outstanding bookings resulting in a backlog of $976 million, which represents a 32% year-over-year increase; (e) strengthened our leadership team with the appointment of new presidents in our Healthcare and Security divisions; and (f) completed two strategic acquisitions in our Security division and one strategic acquisition in our Optoelectronics and Manufacturing division and signed a letter of intent for a second strategic acquisition in our Optoelectronics and Manufacturing division (which was completed in the first quarter of fiscal 2019).

Leverage Business Infrastructure. Even as we launched new products, entered new markets, and invested substantial amounts in R&D, we actively leveraged our business infrastructure and maintained intelligent cost management.

Growth in Markets and Opportunities. In fiscal 2018, we continued to expand our addressable markets through new product introductions and targeting of markets that did not previously represent a significant source of revenues. This dynamic approach has served, and we believe it will continue to serve, to sustain growth over the long term. Some of our key achievements during fiscal 2018 include the following:

•: Expanding presence with international customers with the launch of a checkpoint CT solution by our Security division.
•: Acquiring three companies and signing a letter of intent for a fourth acquisition.
•: Acquiring product lines and companies that not only leverage our existing operating infrastructure but also provide immediate entry into growing market segments.
•: Entering the sporting event security space to provide screening as a service.

Table of Contents

Building a Foundation for the Future. We continue to make significant targeted investments in R&D and acquisitions. In fiscal 2018, we completed three strategic acquisitions and signed a letter of intent for a fourth strategic acquisition. We believe that these acquisitions and investments, as well as other product development programs that are currently underway, will result in enhanced business outcomes for years to come.

Role of the Compensation Committee

Our Board appoints members to the Compensation Committee. Each member of the Compensation Committee is independent within the meaning of the rules and regulations of the SEC and the Listing Standards, as currently in effect. The Compensation Committee is responsible for establishing and approving all compensation for our Named Executive Officers, including base salaries, annual incentives, long-term equity incentive compensation, benefits and perquisites, and other compensation. The Compensation Committee may delegate certain of its responsibilities to a subcommittee, to individuals or to others.

Compensation for each of our Named Executive Officers (other than our Chief Executive Officer) is recommended to the Compensation Committee by our Chief Executive Officer. Compensation for our Chief Executive Officer is established by the Compensation Committee on its own.

The Compensation Committee has designed an executive compensation program that is focused on the attainment of consistent, long-term stockholder returns through (a) aligning executives' incentives with both single-year and multi-year performance, and (b) attracting and retaining executives with capabilities to lead the Company to excel in a competitive landscape. This structure is designed to emphasize pay for performance while simultaneously mitigating risk exposure.

Executive Compensation Program Elements

The particular elements of the compensation program for our Named Executive Officers consist of both fixed compensation and variable compensation. Consistent with our pay-for-performance philosophy, we structure our compensation program such that fixed compensation is a relatively small percentage of total compensation whereas variable compensation comprises a significant percentage of total compensation. The Compensation Committee takes risk into account when establishing the compensation program and believes that the current structure appropriately balances risk and the desire to focus executives on specific annual and long-term goals while not encouraging unnecessary or excessive risk taking.

Table of Contents

The following is an overview of the elements of our compensation and benefits programs for fiscal 2018:

Pay Element		Description

Base Salary		Fixed cash compensation set based on the duties and scope of responsibilities of each executive officer's position and the experience the individual brings to the position.
Annual Incentives		Cash-based annual incentives that are determined formulaically based on adjusted return on equity ("AROE") metrics.
		The Solutions Incentive Program allows for annual incentives in the form of shares of stock or, at our discretion, cash to be granted to Mr. Mehra based on the achievement of certain pre-established performance metrics.
		Mr. Maginnis received a bonus based upon the parameters set forth in his offer letter.
Long-Term Incentives		The fiscal 2018 program with respect to the Named Executive Officers consisted of performance-based restricted stock units, which are earned based on the achievement of pre-established EBITDA-based metrics for each of the three years following grant, as well as an aggregate three-year metric. In addition, division executive Mr. Mehra received some time-based restricted stock units.
Benefits		Employee Stock Purchase Plan, medical, dental, and vision health insurance plans and life and long-term disability insurance.
Perquisites		For fiscal 2018, perquisites included car allowances for each Named Executive Officer and a housing allowance for Mr. Maginnis.
Retirement		401(k) retirement plan, which includes a Company match.
		Nonqualified deferred compensation plan that permits the deferral of salary and cash incentives at executive officers' election and permits a Company match.
		Nonqualified defined benefit plan, of which our CEO is the only participant.

In fiscal 2018, fixed compensation comprised approximately 14% to 43% and variable compensation comprised approximately 57% to 86% of each Named Executive Officer's total compensation. Average variable compensation for the Named Executive Officers represented 85% of total compensation.

Table of Contents

Fixed Compensation. Fixed compensation is intended to compensate our Named Executive Officers for their ongoing responsibilities and consists of base salary. Base salary is set to attract and retain executive talent. Base salaries for our Named Executive Officers are established at levels considered appropriate in light of the duties and scope of responsibilities of each executive officer's position and the experience the individual brings to the position. Salaries are reviewed periodically, typically on an annual basis.

The Compensation Committee takes a conservative approach with respect to base salary increases. In determining whether base salary levels for fiscal year 2018 were appropriate, the Compensation Committee considered the minimum base salary amount provided for in the Named Executive Officer's employment agreement, as well as a determination of each Named Executive Officer's responsibilities, past performance, and expected future contributions. During fiscal 2018, in order to better align their respective salaries with their overall leadership responsibilities, the Compensation Committee increased to $446,000 and $385,000, respectively, the base salaries of Mr. Edrick and Mr. Sze, each of whose base salary had not been increased since 2012, as well as increased to $424,000 the base salary of Mr. Mehra.

Variable Compensation. Variable compensation provides our Named Executive Officers with the opportunity for substantial rewards for achieving successful performance and contributing toward sustainable and consistent stockholder returns, and consists principally of annual incentive awards and long-term incentive compensation.

Annual Incentive Awards. All corporate Named Executive Officers are eligible for an annual incentive pursuant to our annual incentive program. Annual incentives under this program are designed to focus our participating Named Executive Officers on annual operating achievement and near-term success. Annual incentives are calculated based on a formula tied to AROE metrics and provide for a threshold below which no incentive will be paid and a maximum award level.

Table of Contents

Depending on the level of AROE achieved, corporate executives can earn from 0% to 200% of base salary as follows:

AROE

Less than 10%	0	%
10%	25	%
11%	50	%
12%	75	%
13%	100	%
14%	125	%
15%	150	%
16%	175	%
17% or more	200	%

The Compensation Committee considers AROE to be an effective annual performance measure for assessing the Company's efficient use of capital and return to stockholders. The AROE targets were designed to be challenging yet achievable with significant effort and management skill and were established in order to provide the executives sufficient incentive to create long-term stockholder value while at the same time ensuring appropriate risk management. For fiscal year 2018, we achieved 16% AROE; therefore, participating Named Executive Officers earned annual incentives equal to 175% of base salary. See the "Non-equity Incentive Plan Compensation" column of the Summary Compensation Table.

Mr. Maginnis's fiscal 2018 bonus was based upon the parameters set forth in his offer letter.

Solutions Incentive Program. In 2015, we established an incentive program tied to the performance of our solutions business (the "Solutions Incentive Program"). Mr. Mehra, President of the OSI Solutions Business, is the only Named Executive Officer who participates in this program. Incentives under the Solutions Incentive Program are conditioned on the achievement of certain metrics based on the operating income and bookings of our solutions business (excluding certain operations already existing at the time of the adoption of the program). The operating income and bookings metrics are believed to be challenging, but achievable with significant management effort. For fiscal year 2018, we did not achieve the bookings metric. Therefore, Mr. Mehra did not earn anything under this component of the program. Mr. Mehra was paid $1,150,000 based on the operating income performance of the solutions business.

Long-Term Incentive Program. In order to further promote our philosophy of pay-for-performance and furthering our objective of aligning our executive compensation with our long-term financial goals and factors that create long-term stockholder value as well as incentivizing the desired individual performance of each Named Executive Officer, we have a long-term incentive program.

The grants to our corporate Named Executive Officers during fiscal 2018 were performance based in their entirety, and a significant portion of the grants made to our divisional Named Executive Officers were performance based. The Compensation Committee believes that this vesting structure provides an incentive for our Named Executive Officers to remain with the Company and also focus the Named Executive Officers on consistently achieving corporate performance and business objectives for the benefit of our stockholders.

Our overall long-term incentive program is designed to retain our Named Executive Officers and to align the interests of our Named Executive Officers with the long-term interests of our stockholders, namely the achievement of sustainable, long-term stock price appreciation. All equity awards are made at fair market value on the date of grant (which is the date on which the Compensation Committee authorizes the grant). Under our equity incentive plan as in effect on the date of grant, fair market value is determined by the closing price of our Common Stock on such dates.

Table of Contents

With respect to performance based awards, the Compensation Committee has established a program for long-term performance based incentive grants for our Named Executive Officers. The program provides for yearly grants of equity or equity-tied incentives. Each award is 100% performance based and vests based on the achievement of certain one-, two- and three-year performance targets as well as a three-year performance target tied to objective adjusted EBITDA per share metrics. The metrics incentivize consistent, long-term growth, and were designed to be challenging, but achievable with significant effort and management skill.

Each fiscal year, our Named Executive Officers are awarded an initial grant, which vests if a three-year adjusted EBITDA per share target is achieved. However, if actual three-year performance falls below target, shares in the initial grant would be forfeited as follows:

Actual Performance as a Percentage of Target		Result

95% to 99.9%		10% of shares or units would be forfeited
90% to 94.9%		25% of shares or units would be forfeited
85% to 89.9%		55% of shares or units would be forfeited
Below 85%		100% of shares or units would be forfeited

Additional shares may be earned annually for each initial grant within the three-year performance period if annual targets are exceeded as follows:

Actual Performance as a Percentage of Target		Result

105% to 110%		Vested shares or units equaling 20% of initial grant would be awarded
110% to 115%		Vested shares or units equaling 30% of initial grant would be awarded
115% to 120%		Vested shares or units equaling 40% of initial grant would be awarded
Above 120%		Vested shares or units equaling 50% of initial grant would be awarded

Our adjusted EBITDA per share for fiscal year 2018 was 171% of the fiscal 2018 adjusted EBITDA per share target of $6.00. Therefore, our executive officers earned additional shares as follows: Mr. Chopra, 92,015 shares; Mr. Edrick, 39,875 shares; Mr. Mehra, 11,963 shares; Mr. Sze, 34,507 shares; and Mr. Maginnis, 552 shares.

In the event of a change of control, the initial grant would vest upon the change of control; to the extent actual performance has exceeded target for a full fiscal year at the time of the change of control, performance for any annual periods remaining in association with a particular grant will be assumed to exceed target by the same percentage for the purposes of awarding additional incentive shares or units in connection with the change of control.

The Compensation Committee determines, after consultation with our Chief Executive Officer, the number of equity awards to grant to our Named Executive Officers. The grant amounts for our Chief Executive Officer are determined solely by the Compensation Committee. The Compensation

Committee considers individual performance, including the following quantitative and qualitative factors, as well as overall corporate performance.

Qualitative Factors

Quantitative Factors

•

Quality of the management of units or functions managed by the Named Executive Officer

•

Leadership of personnel under the Named Executive Officer's management

•

Execution of strategically important projects

•

Overall effectiveness of units or functions managed by the Named Executive Officer

•

Contributions to the formulation of Company strategy and tactics

•

Contributions to stockholder value

•

Management of risk

•

Financial performance (including earnings per share and internal metrics)

•

Financial performance metrics for business units managed by the Named Executive Officer

•

Compensation surveys provided by external advisors

For fiscal year 2018 performance share calculation purposes, our Chief Executive Officer, Chief Financial Officer, General Counsel, and President of our solutions business are measured against consolidated Company performance, and division Presidents have their performance results weighted 70% based on their respective division performance and 30% based on consolidated Company performance.

Benefits and Perquisites. Benefits and perquisites are designed to attract and retain key employees. Currently, our Named Executive Officers are eligible to participate in benefit plans available to all employees, including our 401(k) Plan, Employee Stock Purchase Plan, medical, dental, and vision health insurance plans and life and long-term disability insurance plans. The 401(k) Plan, Employee Stock Purchase Plan and the medical, dental and vision plans require each participant to pay a contributory amount. We have elected to pay amounts contributed to medical, dental and vision health insurance plans and life and long-term disability insurance plans on behalf of our Named Executive Officers. In addition, we maintain an executive medical reimbursement plan under which our Named Executive Officers receive reimbursement for out-of-pocket expenses not covered by their health insurance plans. Employee individual plan contributions are subject to the maximum contribution allowed by the Internal Revenue Code. We lease automobiles for or provide an auto allowance to certain of our Named Executive Officers. We also provide a housing allowance to Mr. Maginnis.

We maintain a Nonqualified Deferred Compensation Plan (the "Deferred Compensation Plan") that is unfunded for federal tax purposes and allows certain of our Named Executive Officers and a select group of other managers or highly compensated employees (as designated by the Compensation Committee) to defer a specified percentage of certain compensation, including salary, bonuses and commissions. Distributions may be made in a lump sum (or in installments if elected in accordance with the terms of the Deferred Compensation Plan) upon termination of employment, disability, a specified withdrawal date or death. Additional information about this plan is summarized below under the heading "Nonqualified Deferred Compensation."

We also maintain a Nonqualified Defined Benefit Plan (the "Defined Benefit Plan") that is unfunded for federal tax purposes and that constitutes an unsecured promise by the Company to make payments to participants in the future following their retirement, termination in connection with a change in control of the Company, or their death or disability. Under the terms of the Defined Benefit Plan, a committee designated by the Board may select participants from among our Named Executive Officers and a select group of managers or other highly compensated employees. Currently, Mr. Chopra is the only participant

in this plan. Additional information about this plan is summarized below under the heading "Pension Benefits."

Total Compensation Mix. While the Compensation Committee does not apply a predetermined or mathematical weighting to determine the fixed and variable elements of compensation, the Compensation Committee believes that the elements described above provide a well-proportioned mix of equity based, at risk or performance based compensation, and retention based compensation that produces short-term and long-term incentives and rewards. We believe this compensation mix provides our Named Executive Officers a measure of security as to the minimum levels of compensation that they are eligible to receive, while motivating the Named Executive Officers to focus on the business measures that will produce a high level of corporate performance, as well as reducing the risk of recruitment of highly qualified executive talent by our competitors. The mix of annual incentives and the equity based awards likewise provides an appropriate balance between short-term financial performance and long-term financial and stock performance. We believe that this compensation mix results in a pay-for-performance orientation that is aligned with our compensation philosophy, which takes into account individual, group and Company performance.

Bases for Our Compensation Policies and Decisions

In determining compensation awarded to our Named Executive Officers for fiscal 2018, the Compensation Committee performed a review of both overall and relative individual Named Executive Officer and corporate performance based on the qualitative and quantitative factors described in the table below. The factors considered did not have any predetermined or mathematical weighting; rather, the Compensation Committee considered the overall performance of each executive, considering the factors, and including consideration of unplanned events and issues emerging during the fiscal year. Each factor was evaluated and taken into consideration in the Compensation Committee's overall determination of each Named Executive Officer's total compensation package, including both the amount of compensation as well as allocation of such compensation between short-term and long-term components.

Qualitative Factors

Quantitative Factors

•

Furtherance of long-term goals

•

Individual performance and experience

•

Demonstration of leadership skills and ability

•

Achievement of strategic targets

•

Management of unplanned events and issues emerging during the fiscal year

•

Compensation paid in prior years

Financial performance of Company/division/business unit

•

Peer group compensation and performance data

Compensation surveys provided by external advisors

The Compensation Committee's review included evaluating the compensation of the Named Executive Officers in light of information regarding the compensation practices and corporate financial performance of other companies. In making its determinations, the Compensation Committee reviewed information summarizing the compensation paid at peer group companies and more broad-based compensation surveys. The companies in the fiscal 2018 peer group were developed based on similarity in size and operations within the industries in which we operate as follows:


• AAR Corp.	• Coherent, Inc.	• Esterline Technologies Corporation	• Integer Holdings Corporation	• MTS Systems Corporation	• Palo Alto Networks, Inc.
• ADTRAN, Inc.	• Comtech Telecommunications Corp.	• Fitbit, Inc.	• Invacare Corporation	• National Instruments Corporation	• VeriFone Systems, Inc.
• Astronics Corporation	• Cubic Corporation	• FLIR Systems, Inc.	• Itron, Inc.	• Natus Medical Incorporated	• VIASAT, INC.
• Calix, Inc.	• Daktronics, Inc.	• Infinera Corporation	• Masimo Corporation	• Novanta Inc.	• Viavi Solutions Inc.

In connection with executive compensation decisions for fiscal 2018, the Compensation Committee engaged independent compensation consulting firm, Pearl Meyer. The Compensation Committee also considered broad-based surveys that reflected compensation levels and practices for executives holding comparable positions at the companies covered by the surveys and adjustments based on the cost of living in certain geographic areas. The review of the surveys further assisted the Compensation Committee in determining the appropriate level and mix of compensation for each Named Executive Officer. In connection with its review, the Compensation Committee also considered that certain Named Executive Officers were located in the high cost of living area in the geographic location of our Company headquarters.

While the Compensation Committee did not engage in formal benchmarking with pre-established targets, the Compensation Committee reviewed our actual performance taken as a whole as well as our performance relative to our peer group and established compensation levels at the competitive level that it believed most appropriately corresponded to our comparative performance.

For fiscal 2018, the Compensation Committee decided to increase the base salaries of Mr. Edrick, Mr. Mehra, and Mr. Sze in order to better align their respective salaries with their overall leadership responsibilities. The Compensation Committee believes that the fixed component of compensation is designed to compensate each Named Executive Officer based on the duties and scope of responsibilities of his position and the experience he brings to the position. Consistent with the Company's pay-for-performance philosophy, the variable component of compensation, in the form of annual incentives and performance-based equity grants comprised a significant portion of total compensation.

The Compensation Committee's compensation decisions are designed to encourage performance that enhances long-term stockholder value. The Compensation Committee believes that attracting and retaining executive talent capable of achieving our long-term, strategic objectives is the best way to align executive compensation decisions with the interests of stockholders. The Compensation Committee also believes that meeting financial targets as well as near-term strategic goals demonstrates whether an executive is on track to accomplish longer-term objectives.

Minimum Equity Ownership and Retention Guidelines

We believe that our executive officers should hold a significant amount of Company equity to link their long-term economic interests directly to those of our stockholders. Accordingly, we have established requirements that executive officers own at minimum equity of the Company valued at five times their respective annual base salaries. We believe that this multiple constitutes significant amounts for our executive officers and provides a substantial link between the interests of our executive officers and those of our stockholders. During such time that an executive officer has not attained the share ownership guideline, he is required to retain at least 50% of the shares acquired upon exercise of options or vesting of restricted stock awards or units, net of amounts required to pay taxes and exercise price. We periodically review our minimum equity ownership guidelines. As of June 30, 2018, each of our Named Executive Officers met or exceeded our minimum equity ownership guidelines with the exception of Mr. Maginnis who joined the Company in July 2017.

Clawback Policy

We have adopted a clawback policy. The policy provides that if an accounting restatement is required due to our material non-compliance with any accounting requirements, then we will seek to recover any excess in the cash and equity incentive compensation earned by all of our executive officers, regardless of whether they were at fault or not in the circumstances leading to the restatement, over the prior three years over what they would have earned if there had not been a material non-compliance in the financial statements. Each Named Executive Officer's employment agreement also contains a clawback provision.

Table of Contents

Policy Prohibiting the Hedging or Pledging of Company Stock

We have adopted a policy that prohibits our executive officers and directors from entering into any transaction that is designed to hedge or offset any decrease in the market value of our Common Stock or other equity securities. We have also adopted a policy that prohibits our executive officers and directors from holding Company stock or other equity securities in margin accounts or pledging Company stock or other equity securities as collateral for a loan. As of the date of this Proxy Statement, no shares of Company stock are pledged by any Named Executive Officer or director.

Employment Agreements

We have entered into employment agreements with Messrs. Chopra, Edrick, Mehra, and Sze and an offer letter with Mr. Maginnis. The terms of each of such agreements or arrangements are summarized below under the heading "Employment Agreements." These types of arrangements are used to retain executives and formalize the terms of the executives' employment.

Impact of Accounting and Tax on the Form of Compensation

The Compensation Committee considers applicable tax laws, securities laws and accounting regulations in structuring and modifying its compensation arrangements and employee benefit plans. The Compensation Committee has considered the impact of generally accepted accounting principles on our use of equity based awards. The Compensation Committee also considers the limits on deductibility of compensation imposed by Section 162(m) of the Internal Revenue Code with respect to annual compensation exceeding $1.0 million and Section 280G of the Internal Revenue Code with respect to change in control payments exceeding specified limits.

The tax reform legislation passed in December 2017, generally referred to as The Tax Cuts and Jobs Act ("Tax Act"), substantially modifies Section 162(m) and, among other things, eliminates the "performance based" exception to the $1 million deduction limit with respect to taxable years beginning after December 31, 2017. Effective for the fiscal year beginning July 1, 2018, compensation paid to our Named Executive Officers, including our Chief Financial Officer, will be subject to the limitations on deductibility under Section 162(m), and, subject to certain statutory exceptions for equity compensation granted prior to the enactment of the Tax Act, we will not be able to deduct performance based compensation to our Named Executive Officers, including our Chief Financial Officer, who receive annual compensation in excess of $1 million.

Pay Ratio

Pursuant to the Dodd Frank Act, the SEC adopted a rule requiring annual disclosure of the ratio of the median employee's annual total compensation to the annual total compensation of our Chief Executive Officer. The compensation for our Chief Executive Officer in fiscal year 2018 was approximately 562 times the median pay of our employees.

Median employee total annual compensation: $13,001 (figure converted to United States dollars (USD) from Indian rupees at 1 USD to 68.96859 Indian rupees, the June 28, 2018 exchange rate as published by Oanda.com)

CEO total annual compensation: $7,310,240

Ratio of CEO to median employee compensation: 562 to 1

With respect to the annual total compensation of our Chief Executive Officer, we used the amount reported in the "Total" column of the Summary Compensation Table above. We identified the median employee by reviewing the fiscal year 2018 annual base pay for all individuals, excluding our Chief Executive Officer, who were employed by us on June 30, 2018. We included all employees globally without regard to location, whether employed on a full-time, part-time, or seasonal basis. We did not make any

Table of Contents

assumptions, adjustments, or estimates with respect to compensation other than annualizing the compensation for any full-time employees that were not employed by us for all of fiscal 2018. Using this methodology, we determined that the median employee was a full-time salaried employee located in India. Approximately 60% of our employees are located in countries where the cost of living and wages are substantially lower than in the United States. Compensation rates are set to be market-competitive in the country in which the jobs are performed. Accordingly, the resulting CEO to median employee pay ratio is substantially higher than it would have been if the cost of living and wages in those countries were comparable to the United States.

This pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodology described above. The SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices. Therefore, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

Pension Benefits

We maintain the Defined Benefit Plan. The Defined Benefit Plan constitutes an unsecured promise by the Company to make payments to participants upon vesting. Mr. Chopra is currently the only participant in the Defined Benefit Plan.

Under the terms of his participation, Mr. Chopra will be entitled to a total benefit of $10 million payable over a 5-year period commencing January 1, 2024. The initial payment will be $5.25 million and the remaining payments will be in quarterly installments of $250,000. Mr. Chopra is fully vested in all benefits under the Defined Benefit Plan. In the event of Mr. Chopra's death or disability prior to December 31, 2018, he or his dependents shall be entitled to $10 million payable over 10 years commencing within 60 days following his death or disability, as applicable.

Nonqualified Deferred Compensation

We adopted the Deferred Compensation Plan in May 2008, as amended and restated in April 2014. Under the Deferred Compensation Plan, a select group of our management or highly compensated employees (as designated by the Compensation Committee), including certain of our Named Executive Officers, may defer a specified percentage of their salary, bonuses and commissions and thereby defer taxation of these deferred amounts until actual payment of the deferred amounts in future years. The Named Executive Officers may elect to defer up to 80% of their base salary and up to 100% of other types of eligible compensation. The Deferred Compensation Plan also allows us to make discretionary contributions and matching contributions on behalf of eligible participants.

Participating Named Executive Officers receive market-based returns on their deferred compensation amounts based on the performance of a variety of mutual fund-type investment vehicles chosen by them and which are similar to the investment vehicles made available to all employees participating in the Deferred Compensation Plan. Participants may at any time change their investment allocations among the investment vehicles made available under the Deferred Compensation Plan. The rates of return for the various investment vehicles for deferred amounts in the Deferred Compensation Plan in fiscal 2018 ranged from –0.05% to 27.23%.

Distributions to participants may be made in a lump sum (or in installments if elected in accordance with the terms of the Deferred Compensation Plan) upon termination of employment, disability, a specified withdrawal date or death.

Employment Agreements

We have entered into employment agreements with Messrs. Chopra, Edrick, Mehra, and Sze and an offer letter with Mr. Maginnis.

Deepak Chopra's Employment Agreement

In April 2012, we entered into our current employment agreement with Mr. Chopra, which was effective as of January 1, 2012. Mr. Chopra's employment agreement was amended effective as of July 1, 2015 and December 31, 2017. Unless the agreement is terminated earlier in accordance with its terms, the agreement has a three-year term that automatically renews on each anniversary of the effective date of the agreement for a new three year term. The employment agreement terminates on January 1 following the year in which Mr. Chopra turns 73 (the "Chopra Scheduled Retirement Date"). The agreement provides for an initial annual base salary of $1,000,000. Mr. Chopra is also eligible to receive bonus payments from the bonus pool established by us for our officers and employees and to participate in incentive compensation and other employee benefit plans established by us. Mr. Chopra is also entitled to receive the benefit award specified for him under the Defined Benefit Plan. The agreement contains certain restrictive covenants and other prohibitions that protect our proprietary and confidential information following termination and preclude Mr. Chopra during the term of the agreement and for 18 months thereafter from soliciting for hire any individual that was an executive, supervisor or manager of the Company on, or within 90 days prior to, Mr. Chopra's last date of employment with us. The agreement also contains a clawback provision whereby Mr. Chopra's incentive or performance based compensation shall be subject to reduction or repayment by reason of a correction or restatement of our financial information if and to the extent such reduction or repayment is required by any applicable law.

Table of Contents

Under the terms of the agreement, we may terminate Mr. Chopra's employment at any time for "cause" (as defined in the agreement), or for the following additional reasons: (i) in the event of Mr. Chopra's death; (ii) because of physical or mental incapacity or disability, failure to perform the essential functions of his position for an aggregate period of 180 days within any 12 month period; or (iii) without cause on 12 months written notice, each as further detailed in the agreement. Mr. Chopra may also terminate his employment agreement at any time upon 12 months written notice to the Company or upon three months' notice if such termination is for "good reason" (as defined in the agreement).

In the event of the termination of Mr. Chopra's employment by us without cause, our non-renewal of Mr. Chopra's employment agreement, or termination of such employment by Mr. Chopra for good reason, Mr. Chopra shall be entitled to a single lump-sum payment equal to three times the average of Mr. Chopra's highest two years out of the prior five years of total annual compensation, including: (i) base salary; (ii) bonuses and incentive compensation excluding "special bonus programs" (as defined in the agreement); (iii) the fair value of any stock, options or other equity grants whether vested or not and (iv) the annualized value of all benefits and perquisites. Mr. Chopra would also receive the acceleration of vesting of all stock options, equity grants and other incentive compensation awards (excluding any cash bonus attributable to performance in fiscal years that are not complete as of Mr. Chopra's last date of employment and any special bonus programs) from us to Mr. Chopra and an extension of time to exercise such stock options such that Mr. Chopra's right to exercise such stock options shall continue until the first anniversary of the last day of his employment, but in no event later than the expiration date of the options.

In the event of the termination of Mr. Chopra's employment by us without cause or by Mr. Chopra for good reason, within 90 days prior to or 12 months after a "change in control" (as defined in the agreement), then Mr. Chopra shall be entitled to the same lump sum payment described in the previous paragraph, which shall be subject to mitigation as provided in applicable Treasury Regulations. Mr. Chopra may, at his option, and in lieu of receiving the forgoing, elect to receive a lump sum payment in an amount equal to the product of 2.99 multiplied by Mr. Chopra's "base amount" (as defined in Internal Revenue Code Section 280G(b)(3)); provided that the amount of this alternative payment shall be reduced by the value of acceleration of any equity, stock options, incentive compensation or deferred compensation accelerated by reason of termination to the extent required to be included in the "base amount" pursuant to Internal Revenue Code Section 280G.

In the event of Mr. Chopra's continued employment until the Chopra Scheduled Retirement Date (including if Mr. Chopra becomes disabled or continues performing services for the Company in a different capacity prior to the Scheduled Retirement Date and such disability or other form of services continues through the Scheduled Retirement Date), he shall be entitled to $13,500,000 payable on or within 45 days of the Chopra Scheduled Retirement Date; provided that in the event of Mr. Chopra's death or disability after January 1, 2019, such amount shall be paid within 45 days of such event.

Alan Edrick's and Victor Sze's Employment Agreements

For purposes of this section, Messrs. Edrick and Sze are each individually referred to as the "Executive." In April 2012, we entered into our current employment agreement with each Executive, which were effective as of January 1, 2012. Each Executive's employment agreement was amended, effective as of July 1, 2015. The terms of such agreements are substantially identical. Unless the agreement is terminated earlier in accordance with its terms, the agreement has a one year term that shall automatically be extended for successive one year periods, unless either party delivers notice of non-renewal to the other party at least 30 days prior to the end of the initial term or any renewal period then in effect. The employment agreement terminates on January 1 following the year in which the Executive turns 68. The agreements provide for an initial annual base salary of $402,000 for Mr. Edrick and $350,000 for Mr. Sze. The Executive is also eligible to receive bonus payments from the bonus pool established by us for our officers and employees and to participate in incentive compensation and other employee benefit plans established by us. The agreement contains certain restrictive covenants and other

Table of Contents

prohibitions that protect our proprietary and confidential information following termination and preclude the Executive during the term of the agreement and for 18 months thereafter from soliciting for hire any individual that was an executive, supervisor or manager of the Company on, or within 90 days prior to, the Executive's last date of employment with us. Each Executive's agreement also contains a clawback provision whereby the Executive's incentive or performance based compensation shall be subject to reduction or repayment by reason of a correction or restatement of our financial information if and to the extent such reduction or repayment is required by any applicable law.

Under the terms of the agreement, we may terminate the Executive's employment at any time for "cause" (as defined in the agreement), or for the following additional reasons: (i) in the event of the Executive's death; (ii) because of physical or mental incapacity or disability, failure to perform the essential functions of his position for an aggregate period of 180 days within any 12 month period; or (iii) without cause on 30 days written notice, each as further detailed in the agreement. The Executive may also terminate his employment agreement for "good reason" (as defined in the agreement) or at any time on 30 days written notice.

In the event of the termination of the Executive's employment by us without cause, our non-renewal of the Executive's employment agreement or the termination of such employment by the Executive for good reason, the Executive shall be entitled to: (i) an amount equal to 24 months' salary at the Executive's then-current base salary plus an amount equal to two times the average of the highest three annual bonuses (excluding any special bonus programs) paid by us to the Executive in the five years preceding such termination; (ii) continuation of the Executive's car usage or allowance payments for a period of six months after separation from service; (iii) an allowance of $6,000 for outplacement services; and (iv) acceleration of vesting of all stock options, equity grants and other incentive compensation awards (excluding any cash bonus attributable to performance in fiscal years that are not complete as of the Executive's last date of employment and any special bonus programs) from us to Executive as follows: (a) grants vesting over time shall be fully vested on separation from service, (b) grants vesting based on performance shall be accelerated and fully vested on separation from service without regard to whether the performance targets are met for such performance period, and (c) the time to exercise nonqualified stock options shall be extended such that Executive's right to exercise such stock options shall continue until the first anniversary of the Executive's last date of employment, but in no event later than the expiration date of the options.

In the event of the termination of the Executive's employment by us without cause or by the Executive for good reason, within 90 days prior to or 12 months after a "change in control" (as defined in the agreement), then the Executive shall be entitled to (i) the severance payment described in the applicable paragraph above and (ii) equity, stock options and other incentive compensation awards (excluding any cash bonus attributable to performance in fiscal years that are not complete as of the Executive's last date of employment and any special bonus programs) granted by us to Executive, whether time vested or performance vested, shall, to the extent unvested, immediately vest, and such stock options shall remain exercisable by Executive for no less than 12 months after the date of such separation from service. Under such circumstances, the Executive may, at his option, and in lieu of receiving the forgoing amounts, elect to receive a lump sum payment in an amount equal to the product of 2.99 multiplied by the Executive's "base amount" (as defined in Internal Revenue Code Section 280G(b)(3) excluding payments under any special bonus programs); provided that the amount of this alternative payment shall be reduced by the value of acceleration of any equity, stock options, incentive compensation or deferred compensation accelerated by reason of termination to the extent required to be included in the "base amount" pursuant to Internal Revenue Code Section 280G.

May 1, 2015. Unless the agreement is terminated earlier in accordance with its terms, the agreement has a one year term that shall automatically be extended for successive one year periods, unless either party delivers notice of non-renewal to the other party at least 30 days prior to the end of the initial term or any renewal period then in effect. The employment agreement terminates on January 1 following the year in which Mr. Mehra turns 68. The agreement provides for an initial annual base salary of $352,000, which shall increase to $402,000 per year upon achievement of certain pre-established operating income metrics for the OSI Solutions Business. Mr. Mehra is also eligible to receive bonus payments from the bonus pool established by us for our officers and employees and to participate in incentive compensation and other employee benefit plans established by us.

In the event of the termination of Mr. Mehra's employment by us without cause, the Company's non-renewal of Mr. Mehra's employment agreement or the termination of such employment by Mr. Mehra for good reason, he shall be entitled to: (i) an amount equal to two times his total cash compensation (defined as base salary and annual discretionary bonus earned during the 12 calendar months immediately preceding termination plus the cash equivalent of any awards under the Solutions Incentive Program earned during the six calendar months immediately preceding a termination occurring in 2017, annualized, or during the 12 calendar months immediately preceding a termination occurring in 2018 or thereafter), (ii) continuation of Mr. Mehra's car usage or allowance payments for a period of six months after separation from service; (iii) an allowance of $6,000 for outplacement services; and (iv) acceleration of vesting of all stock options, equity grants and other incentive compensation awards (excluding any cash bonus attributable to performance in fiscal years that are not complete as of Mr. Mehra's last date of employment and any special bonus programs) from us to Mr. Mehra as follows: (a) grants vesting over time shall be fully vested on separation from service, (b) grants vesting based on performance shall be accelerated and fully vested on separation from service without regard to whether the performance targets are met for such performance period, and (c) the time to exercise nonqualified stock options shall be extended such that Mr. Mehra's right to exercise such stock options shall continue until the first anniversary of his last date of employment, but in no event later than the expiration date of the options.

In the event of the termination of Mr. Mehra's employment by us without cause or by Mr. Mehra for good reason, within 90 days prior to or 12 months after a "change in control" (as defined in the agreement), then Mr. Mehra shall be entitled to (i) the severance payment described in the applicable paragraph above and (ii) equity, stock options and other incentive compensation awards (excluding any cash bonus attributable to performance in fiscal years that are not complete as of Mr. Mehra's last date of employment and any special bonus programs) granted by us to Mr. Mehra, whether time vested or performance vested, shall, to the extent unvested, immediately vest, and such stock options shall remain exercisable by Mr. Mehra for no less than 12 months after the date of such separation from service (the "Change in Control Payment").

Potential Payment upon Termination of Employment or Change in Control

The following tables reflect the breakdown of potential payments and benefits upon termination or a change in control required under the Named Executive Officers' current employment agreements or offer letter, as applicable. The tables therefore assume that the terms of the employment agreement or offer letter to which each Named Executive Officer is currently subject had been in effect on June 30, 2018, and that employment terminated on such date. The tables also assume that the price of our Common Stock, on which certain calculations in the following tables are made, was the closing price of our Common Stock on June 29, 2018, the last business day of the fiscal year ($77.33).

Please also note that regardless of the manner in which a Named Executive Officer's employment terminates, the officer is entitled to receive amounts earned during the term of employment. These amounts, which are not included in the following tables, include: (i) regular salary accrued as of the final date of employment; (ii) bonuses accrued as of the final date of employment; (iii) vacation and paid time off accrued as of the final date of employment; (iv) business expense reimbursements not yet paid as of the final date of employment; and (v) amounts contributed under our qualified and nonqualified deferred compensation plans.

Gerald Chizever	116,000	169,527	—	285,527

(1): We have omitted from this table the columns titled "Non-Equity Incentive Plan Compensation," "Change in Pension Value and Nonqualified Deferred Compensation Earnings" and "All Other Compensation" because no amounts would have been included in such columns.
(2): Amounts are calculated utilizing the accounting guidance related to stock-based compensation under accounting principles generally accepted in the United States. See Note 8 to the Consolidated Financial Statements included in our Form 10-K for the year ended June 30, 2018 for a discussion of the assumptions used in valuation of stock awards. For the fiscal year ended June 30, 2018, 2,944 RSUs were granted to Mr. Good; 2,576 RSUs were granted to Mr. Luskin; 2,515 RSUs were granted to Dr. Ballhaus; 2,147 RSUs were granted to Mr. Hawkins; and 2,147 RSUs were granted to Mr. Chizever, all with a fair value of $78.96. As of June 30, 2018, Mr. Good had 10,744 unvested stock awards outstanding; Mr. Luskin had 10,376 unvested stock awards outstanding; Dr. Ballhaus had 7,865 unvested stock awards outstanding; Mr. Hawkins had 4,387 unvested stock awards outstanding; and Mr. Chizever had 3,610 unvested stock awards outstanding.

Director Share Ownership Requirements

We believe that our directors should hold a significant amount of Company equity to link their long-term economic interests directly to those of our stockholders. Accordingly, we have established requirements that our directors own at minimum equity of the Company valued at five times their annual retainers. We believe that this multiple constitutes significant amounts for our directors and provides a

Table of Contents

substantial link between the interests of our directors and those of our stockholders. During such time that a director has not attained the share ownership guideline, he is required to retain at least 50% of the shares acquired upon exercise of options or vesting of restricted stock or unit awards, net of amounts required to pay taxes and exercise price. We periodically review our minimum equity ownership guidelines. As of June 30, 2018, each of our directors met or exceeded our minimum equity ownership guidelines, with the exception of Mr. Hawkins who was elected as a director in December 2015.

Certain Relationships and Related Transactions

In 1994, we, together with Electronics Corporation of India Limited ("ECIL"), an unaffiliated Indian company, formed ECIL-Rapiscan Security Products Limited, a joint venture under the laws of India ("ECIL Rapiscan"). We own a 36% interest in the joint venture, Mr. Chopra owns a 10.5% interest and Mr. Mehra owns a 4.5% interest. The remaining interest in the joint venture is owned by ECIL. We sell security and inspection kits to ECIL at a price no less favorable to us than the price we charge unaffiliated third parties for such products. To date, our portion of the earnings of ECIL Rapiscan has been immaterial to our financial results and results of operations.

Mohinder Chopra, who is the brother of Deepak Chopra, our Chief Executive Officer, is our Senior Vice President/General Manager India. His total compensation for fiscal year 2018 was valued at approximately $337,000.

Gerald Chizever, a member of our Board, is a partner at Loeb & Loeb LLP. Loeb & Loeb advises the Company in various matters from time to time. The fees paid by the Company to Loeb & Loeb in each of the past three fiscal years were significantly below the applicable threshold outlined in The NASDAQ Stock Market guidelines for determining director independence. Our Board carefully reviewed the nature of our engagement of Loeb & Loeb and the services rendered, including the expertise and relevant experience of the firm, the firm's and specific partners' knowledge of our Company and our business and past legal engagements, and the fees paid in such engagements, and determined that Mr. Chizever is independent under the standards of The NASDAQ Stock Market.

The Audit Committee of the Board reviews proposed transactions in which the Company and any person who is a member of the Board, a nominee to become a member of the Board, an executive officer of the Company, a holder of more than five percent of our voting securities, or any immediate family member of any of the foregoing would have a direct or indirect material interest in the transaction and the amount involved, when added together with the amounts of all other transactions with that related person for that fiscal year, exceeds $75,000. The review involves an evaluation, without participation by any member of the Audit Committee with a direct or indirect material interest in the transaction, of whether the transaction would be on terms at least as favorable to us as those that could have been obtained from unaffiliated third parties. This policy is supported by the Charter of the Audit Committee of the Board.

Compensation Committee Report

The Compensation Committee has reviewed and discussed with management the Compensation Discussion and Analysis provisions to be included in this Proxy Statement. Based on the reviews and discussions referred to above, the Compensation Committee recommends to the Board that the Compensation Discussion and Analysis referred to above be included in this Proxy Statement.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires the executive officers and directors and persons who beneficially own more than 10% of a class of securities registered under Section 12(b) the Exchange Act to file initial reports of ownership and reports of changes in ownership with the SEC. Such officers, directors and stockholders are required by SEC regulations to furnish us with copies of all such reports that they file. None of our directors or executive officers owns more than 10% of our securities. Based solely upon our review of such forms furnished to us during the fiscal year ended June 30, 2018, and written representations from certain reporting persons, we believe that our executive officers and directors have complied with the requirements imposed on them by Section 16(a) of the Exchange Act, with the exception of one untimely Form 4 filing by Mr. Mehra related to a transaction in 2012 that was inadvertently not previously reported.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Audit Fees

The following table represents fees charged for professional audit services rendered by Moss Adams for the audit of our annual financial statements for the years ended June 30, 2017 and 2018 and fees billed by Moss Adams for other services during those years (in thousands):

	FY 2017		FY 2018

Audit Fees	$	1,404	$	1,503
Audit-Related Fees	$	160	$	36
Tax Fees		—		—
All Other Fees		—		—

Total	$	1,564	$	1,539

"Audit Fees" consist of fees billed for professional services rendered for the integrated audit of our consolidated financial statements and the review of our interim consolidated financial statements included in quarterly reports and services that are normally provided by Moss Adams in connection with statutory and regulatory filings or engagements.

The term "Audit-Related Fees" means fees billed for assurance and related services that are reasonably related to the performance of the audit or review of our financial statements other than audit fees. This includes research and analysis on accounting matters performed in conjunction with the audit and professional services for the audit of the financial statements of our 401(k) plan.

The term "Tax Fees" means fees billed for professional services rendered for tax advice, planning and compliance (domestic and international).

The term "All Other Fees" means fees billed for products and services other than for the services described above.

Audit Committee's Pre-Approval Policy

The Audit Committee pre-approves all audit, audit-related and tax services (other than prohibited non-audit services) to be provided by the independent public accountants. The Audit Committee has delegated to its Chairman the authority to pre-approve all other services to be provided by the independent public accountants, up to an aggregate of $50,000 each fiscal year. The Chairman reports each such pre-approval decision to the full Audit Committee at its next scheduled meeting.

Independence

The Audit Committee has considered whether Moss Adams' provision of services other than its audit of the Company's annual financial statement and its review of the Company's quarterly financial statements is compatible with maintaining such independent public accountant's independence and has determined that it is compatible.

REPORT OF AUDIT COMMITTEE

During the fiscal year ended June 30, 2018, the Audit Committee was composed of four non-employee directors, namely, Steven C. Good, Meyer Luskin, William F. Ballhaus, and James B. Hawkins. All members of the Audit Committee meet the independence and experience requirements of the SEC and Listing Standards. Our Board has determined that Mr. Good qualifies as an "Audit Committee Financial Expert" as this term has been defined under the rules and regulations of the SEC. To date, no determination has been made as to whether the other members of the Audit Committee qualify as Audit Committee Financial Experts. The Audit Committee met four times during the fiscal year ended June 30, 2018.

At each of its meetings, the Audit Committee met with the senior members of our financial management team and the independent public accountants. The Audit Committee's agenda is established by the Audit Committee's Chairman and our Chief Financial Officer. During the year, the Audit Committee had private sessions with our independent public accountants at which open discussions of financial management, accounting and internal control issues took place.

The Audit Committee recommended to the Board the engagement of Moss Adams as our independent public accountants. The Audit Committee reviewed with our financial managers and the independent public accountants overall audit scopes and plans, the results of internal and external audit examinations, evaluations by the auditors of our internal control, and the quality of our financial reporting.

The Audit Committee has reviewed with management the audited financial statements in the Annual Report, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements. In addressing the quality of management's accounting judgments, members of the Audit Committee asked for management's representations that our audited consolidated financial statements have been prepared in conformity with generally accepted accounting principles and have expressed to both management and the independent public accountants their general preference for conservative policies when a range of accounting options is available.

The Audit Committee believes that by thus focusing its discussions with the independent public accountants, it can promote a meaningful dialogue that provides a basis for its oversight judgments.

The Audit Committee also discussed with the independent public accountants all other matters required to be discussed by the independent public accountants with the Audit Committee under Statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1, AU section 380), as adopted by the Public Company Accounting Oversight Board ("PCAOB") in Rule 3200T. The Audit Committee received and discussed with the independent public accountants their annual written report on their independence from our Company and our management, which is made under PCAOB Ethics and Independence Rule 3526 (Communicating with Audit Committee Concerning Independence), and considered with the independent public accountants whether the provision of services provided by them to our Company during the fiscal year ended June 30, 2018 was compatible with the independent public accountants' independence.

Finally, the Audit Committee reviewed and discussed with management and the independent public accountants the evaluation of our internal control and the audit of management's report on the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes Oxley Act of 2002.

In performing all of these functions, the Audit Committee acts only in an oversight capacity. The Audit Committee reviews our SEC reports prior to filing and all quarterly earnings announcements in advance of their issuance with management and representatives of the independent public accountants. In its oversight role, the Audit Committee relies on the work and assurances of our management, which has the primary responsibility for financial statements and reports, including evaluating the effectiveness of

Table of Contents

disclosure controls and procedures, and evaluating the effectiveness of internal control over financial reporting, and of the independent public accountants, who, in their report, express an opinion on the conformity of our annual financial statements with accounting principles generally accepted in the United States of America, as well as expressing an opinion on (i) management's assessment of the effectiveness of internal control over financial reporting and (ii) the effectiveness of internal control over financial reporting.

In reliance on these reviews and discussions, and the report of the independent public accountants, the Audit Committee recommended to the Board, and the Board approved, that the audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2018, for filing with the SEC.
