PROXY STATEMENT
for
Annual Meeting of Shareholders
April 23, 2018

The Board of Directors (the "Board") of Innovative Solutions and Support, Inc. ("ISS" or the "Company") is soliciting your proxy to vote your shares at the Company's 2018 annual meeting of shareholders (the "Annual Meeting"). The Annual Meeting will be held on April 23, 2018 at 10:00 a.m., local time, at the Company's corporate offices at 720 Pennsylvania Drive, Exton, Pennsylvania. ISS intends to mail a Notice of Internet Availability of Proxy Materials (sometimes referred to as the "Notice"), and to make this Proxy Statement available to its shareholders of record entitled to vote at the Annual Meeting, on or about March 12, 2018.

ABOUT THE MEETING

Your vote is important.

In accordance with the rules and regulations adopted by the Securities and Exchange Commission ("SEC"), instead of mailing a printed copy of the proxy materials to each shareholder of record, the Company may now furnish proxy materials, including this Proxy Statement, the proxy card, and the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2017 (the "Annual Report") to the Company's shareholders by providing access to such documents on the Internet. Shareholders will not receive printed copies of the proxy materials unless requested. Instead, the Notice will instruct shareholders as to how they may access and review all of the proxy materials. The Notice also instructs shareholders how to submit a proxy through the Internet. If you would like to receive a paper copy or e-mail copy of your proxy materials, you should follow the instructions for requesting such materials included in the Notice. ISS will pay the entire cost of preparing, assembling, printing, mailing, and distributing these proxy materials, and soliciting votes. If you choose to access the proxy materials and/or vote over the Internet, you are responsible for any Internet access charges you may incur.

You may revoke this proxy at any time before it is voted by written notice to the Chief Financial Officer of the Company, Relland M. Winand, by submission of a proxy bearing a later date, or by casting a ballot at the Annual Meeting. Properly executed and delivered proxies that are received before the Annual Meeting's adjournment will be voted in accordance with the directions provided or, if no directions are provided, your shares will be voted by one of the individuals named on your proxy card, as recommended by the Board. If you wish to give a proxy to someone other than those named on the proxy card, you should cross out those names and insert the name(s) of the person(s), not more than three, to whom you wish to give your proxy.

If you want to vote in person at the Annual Meeting and you hold shares of Company common stock in "street name," you must obtain a proxy card from your broker and bring that proxy card to the Annual Meeting, together with a copy of a brokerage statement reflecting your common stock ownership as of the record date.

Table of Contents

Who can vote?

You can vote if, as of the close of business on February 1, 2018, you were a shareholder of record of the Company's common stock. On that date, 16,840,599 shares of ISS common stock were outstanding and entitled to vote. The Company does not have any other classes of voting stock outstanding other than ISS common stock. Each share of common stock is entitled to one vote, and there are no cumulative voting rights when voting for directors. A list of shareholders eligible to vote will be available at the offices of Innovative Solutions and Support, Inc., 720 Pennsylvania Drive, Exton, Pennsylvania 19341 beginning March 12, 2018. Shareholders may examine this list during normal business hours for any purpose relating to the Annual Meeting.

If you and other residents at your mailing address own shares of common stock in "street name," your broker or bank may have notified you that your household will receive only one annual report and proxy statement, or one notice of internet availability of proxy materials, as applicable, for each company in which you hold stock through that broker or bank. This practice is known as "house-holding." Unless you responded that you did not want to participate in "house-holding," you were deemed to have consented to the process. Each shareholder will continue to receive a separate proxy card or voting instruction card.

If you did not receive an individual copy of this year's Proxy Statement or Annual Report, ISS will send a copy to you if you address a written request to the Company's Chief Financial Officer, Relland M. Winand, 720 Pennsylvania Drive, Exton, Pennsylvania 19341, telephone (610) 646-9800.

If you would like to receive your own set of the Company's future annual reports, proxy statements and other annual disclosure documents, or if you share an address with another Company shareholder and, together, both of you would like to receive only a single set of such documents, you should contact your broker or bank, or you may contact the Company at the above address and phone number.

What constitutes a quorum?

The presence at the Annual Meeting, in person or by proxy, of shareholders entitled to cast at least a majority of the votes that all shareholders are entitled to cast on a particular matter to be acted upon at the meeting shall constitute a quorum for the purpose of consideration and action on the matter. Abstentions from voting and broker "non-votes" will be counted toward a quorum. A broker "non-vote" occurs when the nominee holding a shareholder's shares does not vote on a particular proposal because the nominee does not have discretionary voting power on that item and has not received instructions from the shareholder.

What vote is required and what is the method of calculation?

In accordance with the Company's Amended and Restated Bylaws, an affirmative vote of a majority of the votes properly cast at the Annual Meeting is required for approval of all matters. Abstentions or broker "non-votes" will not be counted for or against matters to be acted on at the Annual Meeting.

What matters will be voted on?

The Board does not intend to bring any other matters before the Annual Meeting except the matters listed in the Notice of Annual Meeting of Shareholders, and the Board is not aware of anyone else who will submit any other matters to be voted on. However, if any other matters are properly submitted before the Annual Meeting to be voted on, the people named on the proxy card, or their substitutes, will be authorized to vote on those matters in their own judgment.

Table of Contents

How do I vote by proxy?

Most shareholders have three ways to vote by proxy: by telephone, by the Internet, or by return of the proxy card. To vote by telephone or by the Internet, you must follow the instructions set forth on the Notice that you receive. To vote by mail, you must sign and date each proxy card you receive, mark the boxes indicating how you wish to vote, and return the proxy card. Do not return the proxy card if you vote by telephone or by the Internet.

Can I change my vote after I return my proxy card?

Yes. You can change or revoke your proxy at any time before the Annual Meeting either by notifying the Company's Secretary and Chief Financial Officer in writing or by sending another executed proxy card dated later than the first proxy card. Your attendance at the Annual Meeting will not cause your previously granted proxy to be revoked unless you specifically so request. For shares of common stock that you hold beneficially, you may change or revoke your proxy by submitting new voting instructions to your broker or nominee.

Can I vote in person at the Annual Meeting instead of voting by proxy?

Yes. However, the Company encourages you to vote by proxy to ensure that your shares of common stock are represented and voted. If you attend the Annual Meeting in person, you may then vote in person even though you returned your proxy card.

Who pays for this proxy solicitation?

The Company will pay all costs in connection with the Annual Meeting, including the cost of preparing, assembling, and mailing the Notice, Proxy Statement, and proxy card, as well as handling and tabulating the proxies returned. In addition to the use of mail, proxies may be solicited by directors, officers, and employees of the Company, without additional compensation, in person, or by telephone or other electronic means. The Company will reimburse brokerage houses and other nominees for their expenses in forwarding proxy material to beneficial owners of the Company's common stock.

Who can help answer your questions?

If you have questions about the Annual Meeting or would like additional copies of this Proxy Statement, you should contact the Company's Chief Financial Officer, Relland M. Winand, 720 Pennsylvania Drive, Exton, Pennsylvania 19341, telephone (610) 646-9800.

Annual Report

On written request, ISS will provide, without charge, a copy of its Annual Report (including a list briefly describing the exhibits thereto), filed with the SEC, to any record holder or beneficial owner of its common stock on February 1, 2018, the record date, or to any person who subsequently becomes such a record holder or beneficial owner. Requests should be directed to the attention of the Company's Chief Financial Officer at the address set forth above.

EQUITY COMPENSATION PLAN INFORMATION

The following table provides information about ISS common stock that may be issued upon the exercise of options and rights under all of the Company's existing equity compensation plans and arrangements as of September 30, 2017, including the 1998 Stock Option Plan (the "1998 Plan"), and the 2009 Stock-Based Incentive Compensation Plan (the "2009 Plan").

Plan Category		Weighted-average exercise price of outstanding options, warrants, and rights

Equity compensation plans approved by security holders	586,834	$	3.47	259,598
Equity compensation plans not approved by security holders	—		—	—
Total	586,834	$	3.47	259,598

In the fiscal years ended September 30, 2017, 2016, and 2015, awards issued to non-employee directors under the Company's existing equity compensation plan and arrangements were 67,115, 56,376 and 21,640, shares, respectively.

2009 Stock-Based Incentive Compensation Plan

The Company's 2009 Plan was approved by the Company's shareholders at the Company's Annual Meeting of Shareholders held on March 12, 2009. The 2009 Plan authorizes the grant of stock appreciation rights, restricted stock, options, and other equity-based awards (collectively referred to as "Awards"). Options granted under the 2009 Plan may be either "incentive stock options", as defined in section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), or nonqualified stock options, as determined by the Compensation Committee of the Company's Board of Directors (the "Compensation Committee").

Subject to an adjustment necessary upon a stock dividend, recapitalization, forward split or reverse split, reorganization, merger, consolidation, spin-off, combination, repurchase or share exchange, extraordinary or unusual cash distribution, or similar corporate transaction or event, the maximum number of shares of common stock available for awards under the 2009 Plan is 1,200,000, all of which may be issued pursuant to Awards of incentive stock options or nonqualified stock options. In addition, the 2009 Plan provides that no more than 300,000 shares may be awarded in any calendar year to any employee as a performance-based award under Section 162(m) of the Code. As of September 30, 2017, there were 259,598 shares of common stock available for Awards under the 2009 Plan.

If any Award is forfeited, or if any option terminates, expires, or lapses without being exercised, the related shares of common stock subject to such Award will again be available for future grant. Any shares tendered by a participant in payment of the exercise price of an option or the tax liability with respect to an Award (including, in any case, shares withheld from any such Award) will not be available for future grant under the 2009 Plan. If there is any change in the Company's corporate capitalization, the Compensation Committee must proportionately and equitably adjust the number and kind of shares of common stock which may be issued in connection with future Awards, the number and type of shares of common stock covered by Awards then outstanding under the 2009 Plan, the number and type of shares of common stock available under the 2009 Plan, the exercise or grant price of any Award, or if deemed appropriate, make provision for a cash payment with respect to any outstanding Award, provided that no adjustment may be made that would adversely affect the status of any Award that is intended to qualify for an exemption from the deductibility limitation under Section 162(m) of the Code, unless otherwise determined by the Compensation Committee. In addition, the

Table of Contents

Compensation Committee may make adjustments in the terms and conditions of any Awards, including any performance goals, in recognition of unusual or nonrecurring events affecting the Company or any subsidiary, or in response to changes in applicable laws, regulations, or accounting principles, provided that no adjustment may be made that would adversely affect the status of any Award that is intended to qualify for an exemption from the deductibility limitation under Section 162(m) of the Code, unless otherwise determined by the Compensation Committee.

The 2009 Plan will terminate on March 12, 2019, unless earlier terminated by the Board. Termination will not affect Awards outstanding at the time of termination. The Board may amend, alter, suspend, discontinue, or terminate the 2009 Plan without shareholder approval, provided that shareholder approval is required for any amendment which (i) would increase the number of shares subject to the 2009 Plan; (ii) would decrease the price at which Awards may be granted; or (iii) would require shareholder approval by law, regulation, or the rules of any stock exchange or automated quotation system.

1998 Stock Option Plan

The Company's 1998 Plan was adopted in order to recognize the contributions made by the Company's employees, directors, consultants, and advisors, to provide such persons with additional incentives to devote their efforts to the Company's future success and to improve the Company's ability to attract, retain, and motivate individuals through the receipt of Company stock options. The maximum number of shares of the Company's common stock available under the 1998 Plan was 3,389,025 (after giving effect to stock splits). The 1998 Plan authorized the grant of "incentive stock options" (within the meaning of Section 422 of the Code) and non-qualified stock options, such options to vest and become exercisable as specified in separate written agreements between the Company and the option recipient. Unless otherwise specified in such agreement, all outstanding options become fully vested and exercisable upon a change in control. The 1998 Plan expired on November 13, 2008; therefore, no further options can be awarded under the 1998 Plan.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), requires the Company's officers (as defined under Section 16(a) of the Exchange Act), directors, and persons who own greater than 10% of a registered class of the Company's equity securities to file reports of ownership and changes in ownership with the SEC. Based solely on a review of the forms the Company has received and on written representations from certain reporting persons that no such forms were required for them, the Company believes that during the fiscal year ended September 30, 2017, the officers, directors, and 10% beneficial owners of the Company complied with all of the applicable filing requirements of Section 16(a) of the Exchange Act, except that on January 18, 2017, a late Form 4 was filed on behalf of Mr. Bressner reporting a grant of 14,234 restricted stock units to Mr. Bressner on January 2, 2017.

AMENDMENT TO AMENDED & RESTATED BYLAWS

(Item 1 on Proxy Card)

BACKGROUND OF THE PROPOSAL

The Company's Amended & Restated Bylaws (the "Bylaws") currently provide for a classified Board of Directors divided into three classes, with each class being elected for a three-year term. On February 15, 2018, the Board approved, and recommended that the shareholders approve, an amendment (the "Bylaws Amendment") to the Bylaws to declassify the Board and provide for the annual election of directors, effective at the 2018 Annual Meeting.

PROPOSED AMENDMENT TO SECTION 3-1 OF THE BYLAWS

After careful consideration, the Board has determined that it is advisable and in the best interests of the Company and its shareholders to declassify the Board to allow the Company shareholders to vote on the election of directors generally on an annual basis, rather than on a staggered basis.

The Board carefully considered the advantages and disadvantages of the current classified structure. In reaching its determination to propose the declassification of the Board, it concluded that the benefits of a classified structure, including maintaining continuity of experience and encouraging a person seeking control of the Company to initiate arm's length discussions with management and the Board, were outweighed by the following considerations:

•: The Board's belief that providing the Company shareholders with the opportunity to annually register their views on the collective performance of the Board and on each director individually will further the Company's goal of ensuring that its corporate governance policies conform to best practices and maximize accountability to the shareholders;
•: Discussions with certain of Company shareholders who prefer the annual election of directors; and
•: The growing sentiment among the investment community in favor of the annual election of directors.

If the Bylaws Amendment is adopted by the Company shareholders, beginning at the 2018 Annual Meeting and at each annual meeting of shareholders thereafter, all directors scheduled to stand for election will be eligible to serve a one-year term expiring at the subsequent annual meeting of shareholders.

If the Bylaws Amendment is not adopted by the Company shareholders, the Board will remain classified and the current Class III directors standing for election at the 2018 Annual Meeting will be eligible to serve a three-year term expiring at the 2021 annual meeting of shareholders.

TEXT OF THE PROPOSED AMENDMENT

The text of the proposed Bylaws Amendment is as follows:

Section 3-1.

(a) General Powers. Except as otherwise provided by law and these Bylaws, all powers of the Corporation shall be exercised by or under the authority of, and the business and affairs of the Corporation shall be managed under the direction of the Board of Directors. Unless the Pennsylvania BCL permits otherwise, this Section 3-1(a) may be modified only by a Bylaw amendment adopted by the shareholders.

(b) Number. The number of members of the Board of Directors shall be the number of Directors serving at the time of adoption of this Section 3-1, or such other number as may thereafter

Table of Contents

from time to time (i) be determined by the Board of Directors, or (ii) be set forth in a notice of a meeting of shareholders called for the election of a full Board of Directors; provided, that if such notice contemplates a change in the size of the Board of Directors, such change shall take effect as of the time the election called for by the notice is held.

(c) Election. Except as provided in Section 3.1(d) of these Bylaws, each Director shall hold office until the next annual meeting of shareholders and until such Director's successor is elected and qualified or until such Director's earlier death, resignation or removal.

(d) Term; Vacancies. Each Director shall hold office until the expiration of the term for which he was elected and until his successor has been elected and qualified or until his earlier death, resignation or removal. Any vacancies on the Board of Directors, including vacancies resulting from an increase in the number of Directors, may be filled by a majority vote of the remaining members of the Board of Directors (though less than a quorum) or by a sole remaining Director or by the shareholders. A director elected by the Board of Directors to fill a vacancy on the Board of Directors shall be elected for an initial term expiring at the next annual meeting of shareholders. If that Director is re-elected by the shareholders at such annual meeting, the Director shall then serve for a term expiring at the annual meeting when the term of a Director would naturally expire.

(e) Qualification. A Director must be a natural person at least 18 years of age.

Effective Date of Amendment. This amendment shall become effective on the date that the Bylaws Amendment is approved by the vote of shareholders entitled to cast at least a majority of the votes which all shareholders are entitled to cast thereon.

BOARD RECOMMENDATION

The Board of Directors recommends voting "FOR" the approval of the Bylaws Amendment.

REQUIRED VOTE

Proposal 1 will only be approved if it is approved by the vote of shareholders entitled to cast at least a majority of the votes which all shareholders are entitled to cast thereon.

Table of Contents

ELECTION OF DIRECTORS

(Item 2 on Proxy Card)

As described in Proposal 1, on February 15, 2018, the Board approved, and recommended that the shareholders approve, an amendment to the Company's Amended and Restated Bylaws (as amended, the " Bylaws ") to declassify the Board, effective at the 2018 Annual Meeting. If the Company shareholders approve Proposal 1 at the Annual Meeting, the shareholders will elect six (6) directors to hold office until the annual meeting of shareholders in 2019, or until their respective successors have been duly elected and qualified. If the Company shareholders do not approve Proposal 1, this Proposal 2 will not be submitted to a vote of the shareholders at the Annual Meeting, and instead, Proposal 3 (Election of Class III Directors) will be submitted in its place.

Upon the recommendation of the Nominating & Corporate Governance Committee of the Board (the "Nominating & Corporate Governance Committee"), the Board has nominated Messrs. Geoffrey S. M. Hedrick, Winston J. Churchill, Robert H. Rau, Roger A. Carolin, Robert E. Mittelstaedt, Jr. and Glen R. Bressner to serve as directors. Each of the foregoing persons currently serves as a director, and each has indicated a willingness to continue to serve as a director; and

Unless contrary instructions are given, the shares represented by a properly executed proxy will be voted " FOR " the elections of each of the nominees. Shareholders must cast a separate vote "FOR" the candidacy of each nominee or to "WITHHOLD AUTHORITY" with respect thereto. Each nominee must receive a majority of the votes cast to be elected. Should either nominee become unavailable to accept election as a director, the persons named in the enclosed proxy will vote the shares that they represent for the election of such other person as the Board may recommend. The Board of Directors recommends voting "FOR" the nominees for directors.

ELECTION OF CLASS III DIRECTORS

(Item 3 on Proxy Card)

Shareholders will be asked to vote on this Proposal 3 solely in the event that, at the Annual Meeting, the shareholders do not approve the adoption of the amendment to the Company's Amended and Restated Bylaws to declassify the Board, effective at the 2018 Annual Meeting, as described in Proposal 1. If the shareholders approve Proposal 1, then the Company will amend its Bylaws to eliminate the classified Board and the shareholders will proceed to vote on Proposal 2, and not this Proposal 3. If, however, the shareholders do not approve Proposal 1, a vote will be taken on this Proposal 3.

If the shareholders do not approve Proposal 1, the shareholders will elect two Class III directors to hold office until the annual meeting of shareholders in 2021, or until their respective successors have been duly elected and qualified. If the shareholders do not approve Proposal 1, the Board will continue to be divided into three classes serving staggered three-year terms, the term of one class of directors to expire each year. The current term of the Class III directors expires at the Annual Meeting.

Upon the recommendation of the Nominating & Corporate Governance Committee, the Board has nominated Mr. Geoffrey S. M. Hedrick and Mr. Winston J. Churchill to serve as Class III directors. Mr. Hedrick and Mr. Churchill serve presently as Class III directors, and each has indicated a willingness to continue to serve as a director.

Unless contrary instructions are given, the shares represented by a properly executed proxy will be voted "FOR" the elections of Mr. Hedrick and Mr. Churchill. Shareholders must cast a separate vote "FOR" the candidacy of each nominee or to "WITHHOLD AUTHORITY" with respect thereto. Each nominee must receive a majority of the votes cast to be elected. Should either nominee become unavailable to accept election as a director, the persons named in the enclosed proxy will vote the shares that they represent for the election of such other person as the Board may recommend. The Board of Directors recommends voting "FOR" the nominees for Class III directors.

In addition, Mr. Churchill has maintained a pilot's license for twelve years and has Instrument and Multi-Engine ratings. Consequently, he brings the Board operational experience with state of the art avionics.

Mr. Rau brings the Board extensive experience in leadership positions with companies in the aviation industry. From this experience, he has gained in-depth knowledge of the operational issues facing companies in the aviation industry, which he utilizes in advising the Board and serving on the Compensation Committee (as Chairman), the Audit Committee, and the Investment Committee. Mr. Rau's prior service on the Board of Governors of the Aerospace Industries Association and as Chairman of both the General Aviation Manufacturers Association and the International Advisory Panel of Singapore Aerospace has provided him with a unique perspective on the issues facing the aviation industry as a whole, which he draws upon in his service on the Board.

Table of Contents

INDEPENDENCE

The Board has determined, in its business judgment, that five (5) of the Company's six (6) directors are independent as defined in the applicable NASDAQ Stock Market, LLC ("NASDAQ") listing standards, including that each member is free of any relationships that would interfere with his individual exercise of independent judgment. The following directors were determined to be independent: Glen R. Bressner, Winston J. Churchill, Robert E. Mittelstaedt, Jr., Roger A. Carolin and Robert H. Rau (collectively, the "Independent Directors").

BOARD LEADERSHIP

The Board does not have a formal policy on whether the roles of Chief Executive Officer and Chairman of the Board should be separate. Currently, Mr. Geoffrey S. M. Hedrick serves in both of these positions. The Board believes that it is in the best interests of the Company's shareholders to combine these offices as it promotes information flow between management and the Board, effective decision making, and an alignment of corporate strategy. In addition, Mr. Glen R. Bressner, an Independent Director, serves as Vice Chairman of the Board and as presiding director during executive sessions of Independent Directors. The Board believes that its structural features, including five independent directors on a board currently consisting of six directors, regular meetings of Independent Directors in executive session, an independent Vice Chairman of the Board, and key committees consisting wholly of Independent Directors, provide for substantial independent oversight of the Company's management. However, the Board recognizes that, depending on future circumstances, other leadership models may become more appropriate. Accordingly, the Board will continue to review periodically its leadership structure.

RISK OVERSIGHT

The Company faces a number of risks, including technological and intellectual property risk, regulatory risk, credit risk, liquidity risk, reputational risk, and risk from adverse fluctuations in interest rates. Management is responsible for the day-to-day management of risks faced by the Company, while the Board, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, the Board seeks to ensure that the risk management processes designed and implemented by management are adequate. The Board consults periodically with management regarding the Company's risks.

While the Board is ultimately responsible for risk oversight, the Company's board committees assist the Board in fulfilling its oversight responsibilities in certain areas of risk. The Audit Committee assists the Board in its oversight of risk management in the areas of financial reporting and internal controls. The Compensation Committee assists the Board in oversight of risks related to the Company's compensation policies and programs. The Investment Committee assists the Board in oversight of the risks related to the Company's cash investments. The Nominating & Corporate Governance Committee assists the Board in oversight of risk associated with board organization, membership and structure, succession planning for directors and executive officers, and corporate governance.

COMMITTEES OF THE BOARD OF DIRECTORS

The Board maintains four standing committees: Audit, Compensation, Investment, and Nominating & Corporate Governance.

Audit Committee. The Audit Committee makes recommendations to the Board with respect to various auditing and accounting matters, including the selection and compensation of the Company's independent registered public accounting firm, the scope of the Company's annual audits, fees to be paid to the independent registered public accounting firm, the performance and independence of the Company's independent registered public accounting firm, and the Company's accounting practices.

Table of Contents

The Audit Committee approves all services provided to the Company by the independent registered public accounting firm. The Audit Committee has established procedures for the receipt, retention, and treatment, on a confidential basis, of complaints received by the Company regarding accounting, internal accounting controls, or auditing matters, and the confidential, anonymous submissions by employees of concerns regarding questionable accounting or auditing matters. In addition, the Audit Committee has responsibility for, among other things, the planning and review of the Company's annual and periodic reports and accounts, and the involvement of the Company's independent registered public accounting firm in that process. The members of the Audit Committee are currently Messrs. Bressner (Chairman), Rau and Churchill. The Audit Committee is comprised solely of independent members, as independence for audit committee members is defined by the applicable NASDAQ listing standards. In addition, the Board has determined, in its business judgment, that each member of the Audit Committee is financially literate, and that at least one of the Audit Committee members, Mr. Rau, is an audit committee financial expert, as defined by SEC rules and regulations. The Audit Committee has adopted a formal written charter that has been approved by the Board. The charter specifies the scope of the Audit Committee's responsibilities and procedures for carrying out such responsibilities. A copy of the charter is available on the Company's website, www.innovative-ss.com, under the heading Investor Relations.

Compensation Committee. The members of the Compensation Committee are currently Messrs. Rau (Chairman) and Mittelstaedt, each of whom, in the judgment of the Board, was found to be "independent" as defined by the applicable NASDAQ listing standards. The Compensation Committee is responsible for setting and administering the policies that govern all executive compensation decisions, including annual base salaries, bonuses, and equity-based compensation programs. The Compensation Committee evaluates annually the performance of the Company's Chief Executive Officer and determines or recommends to the full Board the annual base salary, bonus, and equity-based compensation for the Chief Executive Officer. The Compensation Committee relies on the recommendations of the Chief Executive Officer, following the Chief Executive Officer's annual performance reviews of other executive officers, in setting annual base salaries, bonuses, and equity-based compensation for other executive officers.

The Compensation Committee is responsible for reviewing and overseeing the Company's benefit plans, equity incentive plans, and other compensation plans and policies for employees, consultants, directors, and other compensated individuals, including the Chief Executive Officer. The Compensation Committee has adopted a formal written charter that has been approved by the Board. The charter specifies the scope of the Compensation Committee's responsibilities and procedures for carrying out such responsibilities. A copy of the charter is available on the Company's website, www.innovative-ss.com under the heading "Investor Relations."

The Compensation Committee has the authority under its charter to engage the services of outside consultants, advisors, and others to assist the Compensation Committee. However, the Compensation Committee has not retained an outside consultant or advisor to advise it regarding the Company's compensation practices. Instead, the Compensation Committee independently determines the appropriate levels of compensation for executive officers taking into account, among other factors, the performance of such individuals (as determined in annual reviews conducted by the Compensation Committee for the Chief Executive Officer or by the Chief Executive Officer for the other executive officers), the Company's financial performance, cost of living, prior compensation practices, and recruitment and retention needs. The Compensation Committee relies on the recommendations of the Company's Chief Executive Officer in determining whether and how much of a discretionary bonus may be paid to the Company's employees (including executive officers other than the Chief Executive Officer) if the Company's financial performance exceeds the Board's expectations.

Compensation Committee Interlocks and Insider Participation. No member of the Compensation Committee is a former or current executive officer or employee of the Company. There are no

Table of Contents

compensation committee interlocks between the Company and any other entity involving the Company or such entity's executive officers or board members.

Investment Committee. The Investment Committee assists the Board in fulfilling its oversight responsibilities with respect to recommendations pertaining to the investment of excess capital, including with respect to the implementation of the Company's stock repurchase program. Messrs. Churchill (Chairman), Bressner and Rau are currently the members of the Investment Committee.

Nominating & Corporate Governance Committee. The Company has a Nominating & Corporate Governance Committee, consisting of three non-employee directors. The Nominating & Corporate Governance Committee has adopted a formal written charter that has been approved by the Board. The charter specifies the scope of the Nominating & Corporate Governance Committee's responsibilities and procedures for carrying out such responsibilities. A copy of the charter is available on the Company's website, www.innovative-ss.com, under the heading "Investor Relations." The Nominating & Corporate Governance Committee members are currently Messrs. Mittelstaedt (Chairman), Churchill and Bressner, each of whom, in the determination of the Board, is "independent," as defined by the applicable NASDAQ listing standards.

The Nominating & Corporate Governance Committee functions include establishing the criteria for selecting candidates for nomination to the Board, seeking candidates who meet those criteria, making recommendations to the Board of nominees to fill vacancies on or as additions to the Board, and monitoring the Company's corporate governance structure.

The Nominating & Corporate Governance Committee seeks director candidates based upon a number of qualifications and criteria, including independence, knowledge, judgment, character, leadership skills, education, experience, financial literacy, standing in the community, the ability to foster a diversity of backgrounds and views, and the ability to complement the Board's existing strengths relative to the Company's business. In the case of potential independent director candidates, such eligibility criteria must be in accordance with SEC and NASDAQ rules. While the Nominating & Corporate Governance Committee does not have a formal policy with regard to the consideration of diversity in indentifying director nominees, the Nominating & Corporate Governance and the Board believe that it is essential that the Board be able to draw on a wide variety of backgrounds and professional experience among its members. The Nominating & Corporate Governance Committee desires to maintain the Board's diversity through the consideration of factors such as education, skills, and relevant professional experience. The Nominating & Corporate Governance Committee does not intend to nominate representational directors, but instead, considers the entirety of each candidate's credentials in the context of these standards and the characteristics of the Board in its entirety.

The Nominating & Corporate Governance Committee will consider nominees for election to the Board who are timely recommended by shareholders, provided that a complete description of the nominees' qualifications, experience, and background, together with a statement signed by each nominee in which he or she consents to act as such, accompany the recommendations. Such recommendations should be submitted in writing to the attention of Chairman, Nominating & Corporate Governance Committee, at the Company's address at 720 Pennsylvania Drive, Exton, PA, 19341, and should not include self-nominations. Section 3.10 of the Company's Amended and Restated Bylaws contains provisions setting forth the requirements applicable to a shareholder nomination for director. These requirements are summarized in this Proxy Statement under the caption "Shareholder Proposals for 2019 Annual Meeting And Other Matters."

Table of Contents

Each of the current nominees for director listed under the caption "ELECTION OF DIRECTORS" is an existing director standing for re-election. In connection with the Annual Meeting, the Nominating & Corporate Governance Committee did not receive any recommendation for a candidate from any shareholder or group of shareholders owning more than 5% of the Company's common stock.

The Annual Meeting provides an opportunity each year for shareholders to ask questions of or otherwise communicate directly with members of the Company's Board on matters relevant to the Company. Each director is requested to attend the Annual Meeting in person. All six of the Company's then-serving directors attended the Company's 2017 Annual Meeting of Shareholders.

In addition, shareholders may communicate with the Board, or if applicable, to a specific individual director, by sending a written communication to the attention of the Board or such individual director at the following address: 720 Pennsylvania Drive, Exton, PA, 19341, or by facsimile to (610) 646-0150.

Copies of each written communication received at such address or facsimile number will be provided to the Board or to the specific individual director, unless such communication is considered, in the reasonable judgment of the Corporate Secretary or other appropriate company officer, to be improper for submission to the intended recipient. Examples of shareholder communications that would be considered improper for submission include, without limitation, customer complaints, solicitations, communications that do not relate directly or indirectly to the Company or the Company's business, or communications that relate to improper or irrelevant topics.

The Nominating & Corporate Governance Committee conducts an annual assessment of the size and composition of the Board and its committees and reviews with the Board the appropriate skills and characteristics required of Board members. The Nominating & Corporate Governance Committee has not relied upon third-party search firms to identify board candidates, but reserves the right to do so as required. To date, the Nominating & Corporate Governance Committee has relied upon recommendations from a wide variety of its business contacts, including current executive officers, directors, community leaders, and shareholders as a source for potential board candidates.

Neither the Nominating & Corporate Governance Committee nor the Company has engaged or paid any fees to a search firm in connection with the nomination of the directors for election at the Annual Meeting covered by this Proxy Statement.

MEETINGS AND ATTENDANCE

During the fiscal year ended September 30, 2017, the full Board held four (4) meetings. From time to time during fiscal year 2017 the Board met in executive session without members of management present. The Audit Committee met eight (8) times, the Investment Committee met one (1) time, the Compensation Committee met one (1) time and the Nominating & Corporate Governance Committees met one (1) time. All directors attended at least 75% of the meetings of the full Board and the meetings of the committees on which they served.

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM

(Item 4 on Proxy Card)

The Company has retained Grant Thornton LLP ("Grant Thornton") as the independent registered public accounting firm to audit the Company's consolidated financial statements for the fiscal year ending September 30, 2018. Although action by the shareholders on these matters are not required, the Audit Committee and the Board believe it is appropriate to seek shareholder ratification of this selection in light of the role played by the independent registered public accounting firm in

Table of Contents

reporting on the Company's consolidated financial statements. Ratification requires the affirmative vote of a majority of eligible shares present at the Annual Meeting, in person or by proxy, and voting thereon. If this appointment is not ratified by the shareholders, the Audit Committee may reconsider its selection.

One or more representatives of Grant Thornton are expected to attend the Annual Meeting. Representatives of Grant Thornton will have an opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions.

Principal Accountant Fees and Services

Services provided by Grant Thornton for the fiscal years ended September 30, 2017 and 2016 have included audits of the annual consolidated financial statements of the Company, audits of the effectiveness of internal controls over financial reporting as required by the Sarbanes-Oxley Act of 2002, as amended ("Sarbanes-Oxley"), and other services related to filings made with the SEC. The aggregate fees billed by Grant Thornton in connection with services rendered during the fiscal years ended September 30, 2017 and 2016, respectively, were:

	FY 2017		FY2016

Audit Fees	$	360,180	$	343,539
Audit Related Fees		—		—
Tax Fees		—		—

Total	$	360,180	$	343,539

Audit Fees

Audit fees for fiscal years 2017 and 2016 were for professional services rendered for the audit of the Company's annual consolidated financial statements, auditing the effectiveness of the Company's internal controls over financial reporting, review of the interim consolidated financial statements included in quarterly reports, and services that are normally provided by Grant Thornton in connection with statutory and regulatory filings or engagements.

Audit Related Fees

No audit-related fees were paid to Grant Thornton during fiscal years 2017 or 2016.

Tax-Related Fees

All Other Fees

No other fees were incurred in connection with services provided by Grant Thornton during fiscal years 2017 or 2016.

Pre-Approved Policies and Procedures

The Audit Committee's policy is to pre-approve the engagement of accountants to render all audit and tax-related services for the Company and any changes to the terms of the engagement. The Audit Committee pre-approves all proposed non-audit related services to be provided by the Company's independent registered public accounting firm. The Audit Committee reviews the terms of the engagement and a description of the services along with a fee proposal for the engagement. If agreed to by the Audit Committee, the Audit Committee formally accepts the engagement letter and fee

Table of Contents

proposal. Any proposal by the Company's independent registered public accounting firm for non-audit services must be specific as to the particular services to be provided. Management and the independent registered public accounting firm must each confirm to the Committee that each proposed non-audit and non-audit related service is permissible under all applicable legal requirements. Requests can be submitted to the Audit Committee and approved in one of the following ways: by a request for approval of services at a meeting of the Audit Committee, or through a written request to the Audit Committee, which may be approved by a written consent by the Audit Committee or by a designated member of the Audit Committee. The Audit Committee approved all 2017 and 2016 fees paid to Grant Thornton.

Pursuant to the adoption of the Audit Committee Charter (as revised), the Board has adopted a policy which prohibits the Company from entering into non-audit related consulting agreements for financial information systems design and implementation, for certain other services considered to have an impact on independence, and for all other services prohibited by Sarbanes-Oxley and new SEC regulations. The policy also contains procedures requiring Audit Committee pre-approval of all audit and permitted non-audit services provided by the Company's independent registered public accounting firm.

The Board of Directors recommends a vote "FOR" ratification of the appointment of Grant Thornton LLP as the Company's independent registered public accounting firm.

REPORT OF THE AUDIT COMMITTEE

The following report of the Audit Committee will not be deemed incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act of 1933, as amended, or under the Exchange Act, except to the extent that the Company specifically incorporates this information by reference. The following report shall not otherwise be deemed filed under such Acts.

The Audit Committee assists the Board in its oversight of the financial reporting process. The Audit Committee operates pursuant to a charter. As set forth in the charter, management of the Company is responsible for the preparation, presentation and integrity of its financial statements, accounting and financial reporting principles, and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. The Company's independent registered public accounting firm is responsible for auditing the Company's financial statements and expressing an opinion as to their conformity with generally accepted accounting principles in the United States of America ("GAAP"), and for reviewing the Company's unaudited interim financial statements. The Audit Committee reviews and reassesses the adequacy of its charter on an annual basis. It is not the Audit Committee's duty or responsibility to conduct auditing or accounting reviews or procedures. However, the Audit Committee will take the appropriate actions to set an overall corporate "standard" for quality financial reporting, sound business risk practices, and ethical behavior.

The Audit Committee makes recommendations to the Board with respect to the selection and compensation of the Company's independent registered public accounting firm, the scope of the annual audits, and the fees to be paid to the independent registered public accounting firm. In connection with the decision regarding whether to re-appoint the independent auditor each year (subject to shareholder ratification), the Audit Committee conducts an annual assessment of the independent auditor's performance, including, but not limited to, assessing the independent auditor's qualifications and experience, the communication and interactions with the auditor over the course of the previous year, and the auditor's independence, objectivity, and professional skepticism. In addition, the Audit Committee monitors the performance and independence of the Company's independent registered public accounting firm and approves all services provided to the Company by the independent registered public accounting firm. The Audit Committee consults with and reviews recommendations made by the independent registered public accounting firm with respect to financial statements, financial records, and financial controls of the Company. The Audit Committee meets with management periodically to consider the adequacy of the Company's internal controls and discusses with management the Company's disclosure controls and procedures.

The Board, in its business judgment, has determined that each of the three directors on the Audit Committee is independent as required by Rule 5605(c)(2)(A) of the listing standards of the NASDAQ. In addition, the Board has determined that each member of the Audit Committee is financially literate and at least one of the Audit Committee members, Mr. Rau, is an audit committee financial expert as defined by SEC rules and regulations.

In the performance of its oversight function of the Company's overall financial reporting process and the financial statements for the 2017 fiscal year, the Audit Committee has:

•: reviewed and discussed the Company's audited financial statements for the year ending September 30, 2017 with management and with the independent registered public accounting firm for the fiscal year ending September 30, 2017, Grant Thornton;
•: discussed with Grant Thornton the overall scope and plans for its 2017 audit, and met with representatives of the firm, both with and without management present, to discuss the results of its examination, its evaluation of the Company's internal controls, and the overall quality of the Company's financial reporting;

Table of Contents

•: reviewed and discussed management's report on internal control over financial reporting in accordance with Section 404 of Sarbanes-Oxley;
•: discussed with Grant Thornton the matters required to be discussed by Statement on Auditing Standards No. 16, as amended, "Communication With Audit Committees" (AICPA, Professional Standards, Vol. 1. AU section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T, relating to the conduct of the audit, its judgment as to the quality, not just the acceptability of the Company's accounting principles; and

RELATED PARTY TRANSACTIONS

The charter of the Audit Committee provides that it is the responsibility of the Audit Committee to review and approve any transaction between the Company and its officers, directors, and 5% stockholders.

Compensation of Directors

The Company's compensation program for non-employee directors consists of two elements of compensation: meeting fees and restricted stock or restricted stock unit awards. Each non-employee director is entitled to a fee of $1,000 for each Board meeting attended and $1,000 for each in-person committee meeting that is not held on the same day as a Board meeting. Mr. Bressner, in his role as Chairman of the Audit Committee, receives $12,000 per year in addition to the meeting fees and restricted stock or restricted stock unit awards.

The Company also makes annual awards of restricted stock or restricted stock units, with each such unit representing a contingent right to receive one share of common stock upon vesting, to non-employee directors under the 2009 Plan. The number of shares underlying such annual awards are calculated based upon the price of the Company's common stock at the close of business on the first business day of each calendar year and such shares vest on the last business day of such calendar year. A director who resigns during the course of the year will vest in and receive a pro rata portion of the shares that he or she otherwise would have vested in and received had no such resignation occurred, based on the number of days served during the applicable calendar year.

With respect to the fiscal year ended September 30, 2017, the Company's common stock closed at a price of $3.48 per share on January 3, 2017. Accordingly, each non-employee director received a grant of 11,494 shares of restricted stock on January 2, 2018 for service during the calendar year ended December 31, 2017.

In addition, all directors are reimbursed for reasonable travel and lodging expenses actually incurred in connection with required attendance at Board meetings.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

This Compensation Discussion and Analysis provides an overview of the Company's executive compensation program and a description of the material factors underlying the decisions that resulted in the compensation provided to the Company's Chief Executive Officer, President, and Chief Financial Officer for the fiscal year ended September 30, 2017 (referred to herein as our "named executive officers"). The names of the Company's 2017 named executive officers and their titles are:

•: Geoffrey S. M. Hedrick —Chief Executive Officer
•: Shahram Askarpour —President
•: Relland M. Winand —Chief Financial Officer

Objective of the Company's Executive Compensation Policy

The objective of the Company's executive compensation policy is to:

•: attract and retain exceptional individuals as executive officers; and
•: provide key executives with motivation to perform to the full extent of their abilities to maximize the performance of the Company and deliver enhanced value to the Company's shareholders.

What the Company's Executive Compensation Program is Designed to Reward

Overall, the Company's executive compensation program is designed to reward the contributions of each individual executive officer, to ensure that each executive officer's interest is aligned with those of the Company's shareholders, and to provide sufficient incentives to executive officers to ensure their dedication to the Company. As discussed further below, the Company seeks to achieve these goals by providing sufficient base salaries to compensate executives for the day-to-day performance of their duties and awarding cash bonuses when the executive attains the personal or corporate goals and objectives established by the Company. Also, from time to time, the Company grants equity-based awards when it believes that such equity awards will further align the interests of executive officers with those of the Company's shareholders and provide an additional incentive to executive officers to contribute to the achievement of the Company's financial and strategic objectives.

General Executive Compensation Policies

Process for Setting Total Compensation

Generally, upon hiring or promoting a named executive officer, the Compensation Committee sets the initial levels of base salary and other compensation on the basis of subjective factors, including experience, individual achievements, and level of responsibility assumed at the Company, and may consider market compensation practices from time to time. Actual base salaries, cash bonuses, and equity-based awards for each named executive officer may be adjusted from year to year based upon each named executive officer's annual review and level of attainment of personal and corporate goals and objectives, including Company financial performance, shareholder return, and such other factors as the Compensation Committee deems appropriate and in the best interests of the Company's shareholders.

Each named executive officer's annual review is a subjective process whereby the Chief Executive Officer or the Compensation Committee (as applicable, as described below) evaluates various factors relevant to the named executive officer's contributions to the Company, such as the executive's role in the development and execution of strategic plans, leadership skills, motivation, and involvement in

Table of Contents

industry groups. The weight given to such factors may vary from one named executive officer to another.

The Compensation Committee seeks recommendations from the Chief Executive Officer regarding changes to or increases in the overall compensation level or any particular element of compensation for the other named executive officers. In addition, the Chief Executive Officer is principally responsible for reviewing each other named executive officer's performance, and for making recommendations for the Company's compensation plan for such executive officer for the following fiscal year. The Compensation Committee reviews the recommendations of the Chief Executive Officer in light of his proximity to the other executives and his knowledge of their contributions to the Company. The Compensation Committee independently reviews the performance of the Company's Chief Executive Officer.

Historically, the Compensation Committee has not retained an outside consultant or advisor to advise it regarding the Company's executive compensation program. The Compensation Committee did not retain such consultant or advisor for fiscal year 2017. The Compensation Committee also did not consider any peer groups or engage in benchmarking for setting compensation levels for fiscal year 2017.

Consideration of Shareholder Advisory Vote on Executive Compensation

Based upon the vote of the Company's shareholders at the 2017 annual meeting of the shareholders, the Company currently provides its shareholders with the opportunity to cast an advisory vote on executive compensation (a "say-on-pay proposal") once every three (3) years. At the Company's annual meeting of shareholders held in 2017, a substantial majority of the votes cast on the say-on-pay proposal at that meeting were voted in favor of the proposal. The Compensation Committee believes that this voting result affirms shareholders' support of the Company's approach to executive compensation and did not materially change its approach in fiscal year 2017. The Compensation Committee will consider the outcome of the subsequent say-on-pay vote when making future compensation decisions for the named executive officers. The next time the Company is scheduled to hold a say-on-pay vote is at the Company's annual meeting of shareholders to be held in 2020.

Elements of Compensation

The Company's executive compensation program consists of the following elements of compensation, each described in greater depth below:

•: Base Salary;
•: Annual Bonus;
•: Equity-based Compensation;
•: Perquisites; and
•: General Benefits.

In determining the different elements of compensation to provide to the named executive officers, the Compensation Committee does not adhere to a specific allocation between short-term and long-term compensation, or between cash and non-cash compensation. Instead, the Compensation Committee determines the elements of compensation in a manner designed to reward strong financial performance, provide overall compensation opportunities that are sufficient to attract and retain highly skilled named executive officers, and ensure that named executive officers' interests are aligned with those of the Company's shareholders. This may result in the named executive officers receiving all cash compensation in some years (through base salary and annual bonuses) and a combination of cash and equity-based compensation in other years (through base salary, annual bonuses and equity awards).

Table of Contents

Base Salary

The Company pays base salaries to named executive officers because the Company believes that base salaries are essential to recruiting and retaining qualified executives. In addition, base salaries create an incentive for named executive officers to make meaningful contributions to the Company's success because they are subject to increase based on the executive's performance. The Compensation Committee sets the initial base salary level upon the hire or promotion of a named executive officer and may incorporate base salary into related employment contracts. Base salary levels are determined initially based on the named executive officer's previous experience and employment, and the named executive officer's expected duties and responsibilities with respect to the Company. Thereafter, the Compensation Committee may increase a named executive officer's base salary each year based on the results of the named executive officer's annual review (which is conducted by the Chief Executive Officer for each of the other named executive officers and by the Compensation Committee for the Chief Executive Officer), and based on the Compensation Committee's subjective assessment of the Company's overall performance during the preceding year.

The Compensation Committee determined that there would be no increases in the base salaries of the named executive officers during fiscal year 2017.

Annual Bonus Compensation

The Compensation Committee retains discretion to grant bonus compensation to the named executive officers and other employees of the Company outside of the Bonus Plan. From time to time the Company may award discretionary annual bonuses to the named executive officers and may agree, in hiring or promoting a named executive officer, to a target bonus opportunity, expressed as a percentage of base salary, in any case, to be paid only if the Company determines that the Company has attained its financial performance goals or other objectives.

Equity Compensation

The Company awards equity-based compensation to named executive officers in order to provide a link between the long-term results achieved for its shareholders and the rewards provided to named executive officers, thereby ensuring that such officers have a continuing stake in the Company's long-term success. Historically, equity-based compensation has been provided to named executive officers in the form of stock options (see "Equity Compensation Plan Information" section above). Such awards are made at the discretion of the Compensation Committee and are not timed or coordinated with the release of material, non-public information.

No equity awards were granted to any named executive officers during fiscal year 2017.

Perquisites

In fiscal year 2017, the Company provided certain personal benefits to the Chief Executive Officer, as summarized below. The aggregate incremental cost to the Company of the perquisites received by Mr. Hedrick is included in the Summary Compensation Table, below. The Company has, with the approval of the Independent Directors, permitted the Company's Chief Executive Officer to use the Company's corporate aircraft for personal travel and, in past years, to use a corporate automobile. The Compensation Committee believes that use of the Company's aircraft and the automobile represent valuable perquisites for the Chief Executive Officer and is appropriate considering his position and contributions to the Company.

Table of Contents

General Benefits

The following are standard benefits offered to all eligible Company employees, including the named executive officers.

Retirement Benefits. The Company maintains a tax-qualified 401(k) savings plan for all eligible employees, including the named executive officers, known as the IS&S 401(k) Plan (the "Savings Plan"). The Savings Plan is a voluntary contributory plan under which employees may elect to defer compensation for federal income tax purposes under Section 401(k) of the Code. The Company makes a matching contribution to the Savings Plan at one half of each participant's deferral rate, limited to a maximum contribution of 2% of base salary and subject to limitations imposed by the Internal Revenue Code.

Medical, Dental, Life Insurance, and Disability Coverage. The Company makes available medical, dental, life insurance, and disability coverage to all active eligible employees, including the named executive officers.

Other Paid Time-Off Benefits. The Company provides vacation and other paid holidays to all employees, including the named executive officers.

Employment Agreements

It is the Company's general philosophy that all of the Company's employees should be "at will" employees, thereby allowing both the Company and the employee to terminate the employment relationship at any time and without restriction or financial obligation. However, in certain cases, the Company has determined that, as a retention device and a means to obtain non-compete arrangements, employment agreements are appropriate.

The Company entered into an employment agreement with Dr. Askarpour on February 14, 2012 in connection with his promotion to the position of President of the Company. The initial term of the employment agreement began on April 1, 2012 and ended on March 31, 2013. Pursuant to the terms of the agreement, the term extends for one additional year each subsequent April 1, unless either party provides written notice to the other party at least 30 days prior to the expiration of the then-current term that the term will not be renewed. The employment agreement provides for a base salary of $300,000 per year, which the Company determined to be appropriate given Dr. Askarpour's increased duties and responsibilities as President. If Dr. Askarpour's employment is terminated by the Company without "cause," then, subject to Dr. Askarpour's execution and non-revocation of a release of claims in favor of the Company, the Company will continue to pay Dr. Askarpour his base salary at the rate then in effect for a period of six (6) months following his termination date, during which period the Company will also pay Dr. Askarpour's COBRA premiums. The employment agreement contains covenants restricting Dr. Askarpour's ability to compete with the Company or solicit its employees, other service providers, or current, former, or prospective customers for 12 months after the cessation of Dr. Askarpour's employment. The employment agreement also contains standard confidentiality, assignment of invention, and non-disparagement provisions.

Change in Control Benefits

The Compensation Committee has the authority to accelerate the vesting of Company stock options granted to named executive officers under the Company's 2009 Plan upon a change in control of the Company. The Company believes that such accelerated vesting is essential to maintaining the commitment and dedication of its key employees throughout a potential change in control of the

Table of Contents

Company. Unless otherwise determined by the Compensation Committee or provided in an award agreement, "change in control" is generally defined for these purposes as:

•: the acquisition in one or more transactions during any 12-month period by any "person" (as such term is used for purposes of section 13(d) or section 14(d) of the Exchange Act) but excluding, for this purpose, the Company or its Subsidiaries (as defined in the 2009 Plan) or any employee benefit plan of the Company or its Subsidiaries, of "beneficial ownership" (within the meaning of Rule 13d-3 under the Exchange Act) of thirty percent (30%) or more of the combined voting power of the Company's then outstanding voting securities;
•: a change in the composition of the Board during any 12-month period such that the individuals who at the beginning of such period constituted the Board cease to constitute a majority of the Board;
•: the consummation of a merger or consolidation involving the Company, if the shareholders of the Company, immediately before such merger or consolidation, do not own, directly or indirectly, immediately following such merger or consolidation, more than seventy percent (70%) of the combined voting power of the outstanding voting securities of the corporation resulting from such merger or consolidation; or
•: a complete liquidation or dissolution of the Company or a sale or other disposition of all or substantially all of the assets of the Company.

Stock Ownership/Retention Requirements

The Company does not require its named executive officers to maintain a minimum ownership interest in the Company.

Tax and Accounting Considerations

The Company considers tax and accounting implications in determining all elements of its executive compensation program. Section 162(m) of the Code denies a federal income tax deduction for certain compensation exceeding $1,000,000 paid in a taxable year to the Chief Executive Officer or any of the three highest compensated officers (other than the Chief Executive Officer and Chief Financial Officer). Certain performance based compensation is excluded from this deductibility limitation. The Compensation Committee considers the impact of this deductibility limitation on the compensation that it intends to award, and may structure compensation such that it is deductible if it determines that doing so is in the best interest of the Company and consistent with the Company's executive compensation program. The foregoing does not limit the Compensation Committee's discretion to award compensation that is not deductible under Section 162(m) of the Code if it determines that doing so is in the best interest of the Company and consistent with the Company's executive compensation program. Through September 30, 2017, Section 162(m) of the Code has not affected the Company's tax deductions. At the present time, the Compensation Committee believes that it is unlikely that the compensation paid to any of the Company's employees in a taxable year will exceed $1,000,000.

The Compensation Committee considers the impact of various forms of compensation on the Company's financial results. In particular, the Compensation Committee considers the potential impact on current and future financial results of all equity compensation that it approves.

OPTION EXERCISES AND STOCK VESTED

None of our named executive officers exercised options or had stock awards vest during the fiscal year ended September 30, 2017.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

As described in the Compensation Discussion and Analysis section above, Dr. Askarpour's employment agreement provides that if his employment is terminated by the Company without "cause," then, subject to his execution and non-revocation of a release of claims in favor of the Company, the Company will continue to pay Dr. Askarpour his base salary at the rate then in effect for a period of six (6) months following his termination date, during which period the Company will also pay Dr. Askarpour's COBRA premiums. If Dr. Askarpour's employment were terminated by the Company without "cause" on September 30, 2017, the total amounts payable to Dr. Askarpour would be $160,044. For purposes of Dr. Askarpour's employment agreement, "cause" generally means (a) the commission by or conviction of Dr. Askarpour, or plea of guilty or nolo contendere to, a felony or any crime involving dishonesty, disloyalty, or moral turpitude; (b) Dr. Askarpour's willful misconduct or willful failure substantially to perform the duties of his position or his willful refusal to comply with the lawful directives of the CEO or any director of the Company; (c) a breach by Dr. Askarpour of his employment agreement or any written policies of the Company applicable to Dr. Askarpour; (d) any act or omission by Dr. Askarpour constituting dishonesty, fraud or embezzlement, or an intentional violation of Dr. Askarpour's duty of loyalty to the Company under law; (e) Dr. Askarpour's gross negligence in the performance of his duties; or (f) Dr. Askarpour's poor job performance or other improper conduct not otherwise described above, except that cause shall not exist based solely on clauses (e) or (f), unless the Company has given Dr. Askarpour written notice of its intent to terminate his employment for cause, and allowed Dr. Askarpour 30 days to cure such alleged poor job performance or other improper conduct.

As described in the Compensation Discussion and Analysis section above, the Compensation Committee has the authority to accelerate the vesting of Company stock options granted to named executive officers under the Company's 2009 Plan upon a change in control of the Company. None of our named executive officers held unvested options as of September 30, 2017.

SHAREHOLDER PROPOSALS FOR 2019 ANNUAL MEETING
AND OTHER MATTERS

Shareholders wishing to submit proposals for inclusion in the proxy statement for the 2019 annual meeting of shareholders must submit such proposals to the Company at 720 Pennsylvania Drive, Exton, PA 19341, Attention: Relland M. Winand. In order for the proposal to be included in the proxy statement for the 2019 annual meeting of shareholders, the shareholder submitting the proposal must meet certain eligibility standards and comply with the procedures established by the SEC as set forth in Rule 14a-8 of the Exchange Act.

On May 21, 1998, the Securities and Exchange Commission adopted an amendment to Rule 14a-4, issued under the Exchange Act. The amendment to Rule 14a-4(c)(1) governs a company's use of discretionary proxy voting authority for a shareholder proposal which the shareholder has not sought to include in the proxy statement. The amendment provides that if a proponent of a proposal fails to notify a company at least 45 days prior to the month and day of mailing of the prior year's proxy statement (or any date specified in an advance notice provision), then the management proxies will be allowed to use their discretionary voting authority when the proposal is raised at the meeting, without any discussion of the matter in the proxy statement. With respect to the Company's 2019 Annual Meeting of Shareholders, if the Company does not receive notice of a shareholder proposal, which the shareholder has not previously sought to include in the proxy statement, by January 26, 2019, the management proxies will be allowed to use their discretionary authority.

The Company's Amended and Restated Bylaws provide that a shareholder proposal (including a shareholder nomination of a director) must meet certain predetermined requirements in order to be considered at an annual meeting of the shareholders. In order to be considered, a shareholder's proposal must be made in writing and delivered to, or mailed and received at, the Company's principal executive offices not less than one hundred twenty (120) days nor more than one hundred fifty (150) days prior to the date that the Company's proxy statement was released to shareholders in connection with the previous year's annual meeting of shareholders in the case of an annual meeting that is called for a date that is within thirty (30) days before or after the anniversary date of the immediately preceding annual meeting of shareholders. However, in the case of an annual meeting that is called for a date that is not within thirty (30) days before or after the anniversary date of the immediately preceding annual meeting, proposals must be received not later than the close of business on the tenth (10th) day following the day on which notice of the date of the meeting was mailed or public disclosure of the date of the meeting was made, whichever occurs first. The notice to the Secretary must set forth certain information as specified in the Company's Amended and Restated Bylaws. In order to be included in the Company's 2019 Annual Meeting proxy statement any shareholder proposal must be received at the address listed above by November 12, 2019, but not before October 13, 2019, which is 120 days and 150 days, respectively, prior to the anniversary date of the release of this Proxy Statement.

As of the date of this Proxy Statement, the Board knows of no other business which may properly be and is likely to be brought before the Annual Meeting. If a shareholder proposal that was excluded from this Proxy Statement in accordance with Rule 14a-8 of the Exchange Act or the Company's Amended and Restated Bylaws is properly brought before the Annual Meeting, it is intended that the proxy holders will use their discretionary authority to vote the proxies against said proposal. If any other matters should arise at the Annual Meeting, shares of common stock represented by proxies will be voted at the discretion of the proxy holders.
