This information was previously omitted from the Form 10-K in reliance on General Instruction G(3) to Form 10-K, which permits the information in Part III to be incorporated in the Form 10-K by reference from our definitive proxy statement (such definitive proxy statement, when filed, the "Proxy Statement") if such Proxy Statement is filed no later than 120 days after end of our fiscal year. We are filing this Amendment No. 1 to include Part III information in our Form 10-K because we do not expect to file the Proxy Statement within 120 days after the end of the fiscal year covered by the Form 10-K. This Amendment No. 1 amends and restates in their entirety Items 10, 11, 12, 13 and 14 of Part III of the Form 10-K. In addition, as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended, currently dated certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 are filed hereto as Exhibit 31.3 and Exhibit 31.4, respectively, under Item 15 of Part IV.

No other changes have been made to the Form 10-K other than those described above. This Amendment No. 1 does not reflect subsequent events occurring after the original filing date of the Form 10-K or modify or update in any way the financial statements, consents or any other items or disclosures made in the Form 10-K in any way other than as required to reflect the amendments discussed above. Accordingly, this Amendment No. 1 should be read in conjunction with the Form 10-K and the Company's other filings with the SEC subsequent to the filing of the Form 10-K.

References in this Amendment No. 1 to "the Company," "IA," "we," "us," or "our" refer to Innovative Solutions and Support, Inc. unless the context clearly requires otherwise.

[**Table of Contents**](#TOC)

September 30, 2025 (referred to herein as our "named executive officers"). The names of the Company's 2025 named executive officers, together with their titles during the 2025 fiscal year, are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Shahram Askarpour—Director, President and Chief Executive Officer

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Jeffrey DiGiovanni—Chief Financial Officer <sup>(1)</sup>

1) Jeffrey DiGiovanni began his tenure as Chief Financial Officer effective April 8, 2024.

***Objective of the Company's Executive Compensation Program***

The objective of the Company's executive compensation program is to attract and retain exceptional individuals as executive officers and to provide key executives with motivation to perform to the full extent of their abilities to maximize the performance of the Company and deliver increasing 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 annual 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. Granting equity compensation to the Company's executive officers are made at the discretion of the Compensation Committee and are not timed or coordinated with the release of material, non-public information nor is the granting of such awards timed in a manner that would enhance the value of such awards.

**GENERAL EXECUTIVE COMPENSATION POLICIES**

***Process for Setting Total Compensation***

Generally, upon hiring or promoting a named executive officer, the Compensation Committee sets the executive's initial level 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 industry groups. The weight given to such factors may vary from one named executive officer to another and from year to year.

The Compensation Committee seeks recommendations from the Chief Executive Officer regarding changes to 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.

In fiscal years 2023, 2024 and 2025, the Compensation Committee engaged FW Cook to advise the Compensation Committee with respect to best practices, competitive market data based on comparison companies and trends in the area of executive compensation, as well as ongoing regulatory considerations. The Compensation Committee has determined that FW Cook, which does not perform

[**Table of Contents**](#TOC)

any work for the Company other than its services for the Compensation Committee, is independent and that its services do not raise any conflict of interest with the Company or any of the Company's executive officers or directors.

***Consideration of Shareholder Advisory Vote on Executive Compensation***

Based upon the vote of the Company's shareholders at the fiscal 2025 annual meeting of 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 fiscal 2023, over 98% 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' strong support of the Company's approach to executive compensation The Compensation Committee will consider the outcome of the fiscal 2023 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 fiscal 2026.

***Elements of Compensation***

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Base Salary

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Annual Bonus

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Equity-Based Compensation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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).

***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. 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 and considering market data provided by the Company's independent compensation consultant. 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.

***Annual Bonus***

The Compensation Committee retains discretion to grant bonus compensation to the named executive officers and other employees of the Company. 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.

[**Table of Contents**](#TOC)

The named executive officers' fiscal 2025 target annual bonus opportunities were as follows:

---

| | |
|:---|:---|
| **Named Executive Officer** | **Annual Bonus Opportunity as a% of Base Salary** |
| Shahram Askarpour  | 100% |
| Jeffrey DiGiovanni  | 50% |

---

66% of the potential annual incentive opportunity was based on the achievement of financial performance targets and the remaining portion of the annual incentive was based on a qualitative assessment of performance. In fiscal 2025, the Company chose Revenue and Operating Income as its financial performance metrics. In the case of Dr. Askarpour, the qualitative assessment took into account organic growth, progress on mergers and acquisitions, progress on autonomous flight initiatives, increased strategic partnerships and investor relations activities. In the case of Mr. DiGiovanni, the qualitative assessment considered investor relations activities, quality of financial accounting, mergers and acquisitions support, and progress toward additional financing.

Interim Chief Financial Officer, Relland Winand received a discretionary bonus of $125,000. Former Chief Financial Officer, Micheal Linacre's October 8, 2023 resignation resulted in the forfeiture of his fiscal year 2024 bonus.

The fiscal 2024 annual cash incentives were paid to Dr. Askarpour on December 20, 2024 and to Mr. DiGiovanni on December 17, 2024, respectively. Relland Winand's discretionary fiscal 2024 bonus was paid on April 5, 2024. The payments are listed as fiscal 2024 compensation in the Summary Compensation Table in the column labeled "Non-Equity Incentive Plan Compensation."

***Equity-based 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 (see the section titled "Equity Compensation Plan Information" below). 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.

In fiscal 2025, we granted 72,062 market-based stock option shares ("MSOs"), 37,835 time-vested Restricted Stock Units ("RSUs") and 201,000 Market-Based Restricted Stock Units ("MSUs") to Dr. Askarpour and 33,259 MSOs and 17,462 RSUs to Mr. DiGiovanni.

[**Table of Contents**](#TOC)

contributory plan under which employees may elect to defer compensation for federal income tax purposes under Section 401(k) of the Code.

*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 agreement to enter into non-compete arrangements, employment agreements or other contractual agreements are appropriate.

The Company entered into an amended and restated employment agreement with Dr. Askarpour on April 14, 2022 in connection with his appointment as Chief Executive Officer of the Company on January 14, 2022. The initial term of the employment agreement began on April 14, 2022 and will end on April 13, 2024. Pursuant to the terms of the agreement, the term extends for one additional year each subsequent April 14, 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 agreement provides for a base salary of $400,000 per year, which the Company determined to be appropriate given Dr. Askarpour's increased duties and responsibilities as Chief Executive Officer. If Dr. Askarpour's employment is terminated by the Company without "cause" or by Dr. Askarpour for "good reason," 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 twelve (12) 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 twelve (12) months after the cessation of Dr. Askarpour's employment. The employment agreement also contains standard confidentiality, assignment of invention, and non-disparagement provisions.

On September 6, 2024, the Company entered into an amendment (the "Amendment") to amend its employment agreement dated April 14, 2022 (the "Employment Agreement") with Shahram Askarpour, the Company's Chief Executive Officer. The Amendment amends and restates the severance provisions of the Employment Agreement. As amended, if Mr. Askarpour is terminated by the Company without Cause (as defined in the Employment Agreement) or resigns for Good Reason (as defined in the Amendment), Mr. Askarpour will be entitled to (i) payment of his base salary and (ii) payment of COBRA premiums for Mr. Askarpour and his dependents, in each case for 12 months following the date of Mr. Askarpour's termination or resignation. The Amendment further provides that, in the event that Mr. Askarpour's employment is terminated by the Company without Cause or for Good Reason during a period beginning six months prior to, and ending two years following, a Change of Control (as defined in the Employment Agreement), Mr. Askarpour shall receive, in lieu of the severance benefits set forth above, the following benefits from the Company: (i) an amount in cash equal to twice the sum of (a) Mr. Askarpour's base salary and (b) the maximum annual cash bonus and/or other incentive compensation opportunity available to Mr. Askarpour; (ii) immediate vesting of all unvested equity awards held by Mr. Askarpour; (iii) extension of the exercise period with respect to any options held by Mr. Askarpour for a period lasting until the earlier of two years following Mr. Askarpour's termination and the expiration date of the option; and (iv) payment of the employer portion of health and disability insurance coverage substantially comparable to the coverage Mr. Askarpour received from the Company immediately prior to Mr. Askarpour's termination, for a period of 18 months following Mr. Askarpour's termination.

The Amendment provides that delivery by the Company of a Nonrenewal Notice (as defined in the Employment Agreement) to Mr. Askarpour will be treated as a termination without Cause on the last day of the applicable term.

If Mr. DiGiovanni's employment had been terminated by the Company without "cause," then, subject to Mr. DiGiovanni's execution and non-revocation of a release of claims in favor of the Company, the Company would continue to pay Mr. DiGiovanni his base salary at the rate then in effect for a period of six (6) months following his termination date in addition to a pro-rata bonus for the year of termination based on the actual bonus he would have been paid absent such termination. The offer letter contained covenants restricting Mr. DiGiovanni's ability to compete with the Company or solicit its employees, other service providers, or current, former, or prospective customers for twelve (12) months after the cessation of Mr. DiGiovanni's employment.

***Change in Control Benefits***

The Compensation Committee has the authority to accelerate the vesting of Company equity awards granted to named executive officers under the Company's 2019 Stock-Based Incentive Compensation Plan (the "2019 Plan") upon a change in control of the Company (except for certain transactions that are expressly carved out under the 2019 Plan). 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 Company. Unless otherwise determined by the Compensation Committee or provided in an award agreement, "change in control" is generally defined for these purposes as:

&nbsp;&nbsp;&nbsp;&nbsp;·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 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 forty percent (40%) or more of the combined voting power of the Company's then outstanding voting securities;

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;·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;

&nbsp;&nbsp;&nbsp;&nbsp;·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 fifty percent (50%) of the combined voting power of the outstanding voting securities of the corporation resulting from such merger or consolidation; or

&nbsp;&nbsp;&nbsp;&nbsp;·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.

Under Dr. Askarpour's amended and restated employment agreement, if, during the Term, Dr. Askarpour's employment is terminated by IS&S without Cause (and not due to death or Disability, but for the avoidance of doubt, including IS&S's delivery of a Nonrenewal Notice), or by Dr. Askarpour for Good Reason (as defined below), then:

&nbsp;&nbsp;&nbsp;&nbsp;(a) IS&S shall be released from any and all further obligations under this Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;(b) IS&S shall pay Askarpour all salary, benefits, bonuses, reimbursable expenses and all other compensation owing or accrued to Askarpour through the effective date of termination; and;

&nbsp;&nbsp;&nbsp;&nbsp;(c) IS&S shall pay to Askarpour his Base Salary for a period of twelve (12) months following the date of Askarpour's termination, provided such termination occurs outside the Change of Control Period (as defined below).

For purposes of the amended and restated employment agreement, IS&S's delivery of a Nonrenewal Notice to Dr. Askarpour shall be treated as termination without Cause on the last day of the Initial Term or a Renewal Term, as applicable. If Dr. Askarpour and his eligible dependents are eligible for, and timely elect, COBRA continuation coverage, IS&S shall reimburse Dr. Askarpour (or Dr. Askarpour's estate or legal representative, as applicable) for the COBRA premiums for Dr. Askarpour and his eligible dependents under IS&S' benefit plans for the period of Base Salary continuation under clause (c) of the preceding sentence (the "COBRA Benefit"); provided, however, that notwithstanding the foregoing, the COBRA Benefit shall not be provided to the extent that it would result in any fine, penalty or tax upon IS&S; and provided further, that the COBRA Benefit shall cease earlier if Dr. Askarpour or his dependents become eligible for health coverage under the health plan of another employer."

Under Dr. Askarpour's amended and restated employment agreement, in the event that Dr. Askarpour's employment is terminated by IS&S without Cause or Dr. Askarpour resigns with Good Reason within the period beginning six (6) months prior to, and ending two (2) years following a Change of Control (the "Change of Control Period"), (i) IS&S shall pay, or cause to be paid, to Dr. Askarpour an amount equal to two (2) times the sum of (A) the Base Salary immediately prior to the Change of Control and (B) the maximum annual cash bonus and/or other incentive compensation opportunity available to Dr. Askarpour (as determined by the Board in its sole discretion), payable in one lump sum subject to and in accordance with Paragraph 4.10(a) of the September , 2024 amended employment agreement, (ii) all unvested equity awards held by Askarpour shall immediately become fully vested and exercisable, (iii) any options held by Dr. Askarpour at the time of such termination shall continue to be exercisable until the earlier of two (2) years following the date of such termination and the option's original expiration date, and (iv) IS&S shall provide Dr. Askarpour with health (medical, dental and vision) and disability coverage substantially comparable to the coverage Dr. Askarpour was receiving from IS&S immediately prior to the Change of Control for a period of 18 months following such termination (the "Coverage Period"). Dr. Askarpour shall pay the same percentage of the total cost of coverage under the applicable employee benefit plans as Dr. Askarpour was paying when Dr. Askarpour's employment terminated.

For purposes of Dr. Askarpour's employment agreement, Dr. Askarpour shall have "Good Reason" to resign from his employment with IS&S upon the occurrence of any of the following actions taken by IS&S without Dr. Askarpour's prior written consent:

&nbsp;&nbsp;&nbsp;&nbsp;(a)a material reduction in Askarpour's title, duties, responsibilities or authority;

&nbsp;&nbsp;&nbsp;&nbsp;(b)a material reduction of Askarpour's aggregate compensation;

&nbsp;&nbsp;&nbsp;&nbsp;(c)relocation of Askarpour's primary work location that results in an increase in Askarpour's one-way commute by more than twenty-five (25) miles;

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;(d)failure or refusal of a successor to IS&S to either materially assume IS&S' obligations under this Agreement or enter into a new employment agreement with Dr. Askarpour on terms that are materially similar to those provided under this Agreement, in any case, in the event of a Change of Control; or

&nbsp;&nbsp;&nbsp;&nbsp;(e)a material breach of this Agreement by IS&S.

Notwithstanding the foregoing, Good Reason shall not be deemed to exist unless (A) Dr. Askarpour gives IS&S written notice within thirty (30) days after the first occurrence of the event which Dr. Askarpour believes constitutes the basis for Good Reason, specifying the particular act or failure to act which Dr. Askarpour believes constitutes the basis for Good Reason, (B) IS&S fails to cure such act or failure to act within thirty (30) days after receipt of such notice and (C) Dr. Askarpour terminates his employment within thirty (30) days after the end of such 30-day cure period specified in clause (B).

Unless the Board determines otherwise in its sole discretion prior to the consummation of a Change of Control, in the event that a Change of Control is consummated resulting in IS&S becoming a privately-held company, Dr. Askarpour shall not have Good Reason to resign (A) solely on account of the consummation of such transaction or (B) on account of any diminution in the particular duties or responsibilities relating solely to being a public company that he may have held immediately prior to the Change of Control by virtue of his position as the chief executive officer of a public company.

For purposes of Dr. Askarpour's employment agreement, "change in control" is generally defined for these purposes as:

&nbsp;&nbsp;&nbsp;&nbsp;· a "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, any employee benefit plan of the Company or its subsidiaries, is or becomes a "beneficial owner" (within the meaning of Rule 13d-3 under the Exchange Act) of forty percent (40%) or more of the combined voting power of the Company's then outstanding voting securities;

&nbsp;&nbsp;&nbsp;&nbsp;· a change in the composition of the Board during any 2-year period such that the individuals who at the beginning of such period constituted the Board cease to constitute a majority of the Board;

&nbsp;&nbsp;&nbsp;&nbsp;· 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, at least seventy-five percent (75%) of the combined voting power of the outstanding voting securities of the corporation resulting from such merger or consolidation; or

&nbsp;&nbsp;&nbsp;&nbsp;· 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.

On June 20, 2024, the Company entered into a Change in Control Agreement with Mr. DiGiovanni (the "Change in Control Agreement"). Pursuant to the Change in Control Agreement, in the event Mr. DiGiovanni is terminated (i) by the Company without Cause, or (ii) by Mr. DiGiovanni for Good Reason during the period beginning six (6) months prior to and ending two (2) years following a Change in Control of the Company (the terms "Cause," "Change in Control" and "Good Reason" are defined in the Change in Control Agreements), Mr. DiGiovanni will be entitled to receive an amount equal to two (2) times the sum of (A) his base salary in effect immediately prior to the Change in Control, and (B) the maximum annual cash bonus and/or other incentive compensation opportunity available to Mr. DiGiovanni (as determined by the Board in its sole discretion). The Change in Control benefit will be paid in one lump sum on the 60th day following termination of employment, provided that the executive has executed and delivered a release of claims and the statutory period during which he or she may revoke that release has expired on or before that 60th day. Upon such termination, (x) all unvested equity awards held by Mr. DiGiovanni will immediately become vested and exercisable, (y) any options held by Mr. DiGiovanni at the time of such termination will continue to be exercisable until the earlier of two (2) years following the date of such termination and the option's original expiration date, and (z) the Company will provide Mr. DiGiovanni with health (medical, dental and vision) and disability coverage substantially comparable to the coverage Mr. DiGiovanni was receiving from the Company immediately prior to the Change in Control for a period of eighteen (18) months following such termination.

***Stock Ownership/Retention Requirements***

The Company has adopted a Stock Ownership and Retention Policy that applies to its Section 16 officers. We believe that the Stock Ownership and Retention Policy aligns the interests of our management team, directors and shareholders.

The ownership requirement for our CEO and our executive officers is calculated as a multiple of base salary, as noted below:

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Position** | &nbsp;&nbsp;**Minimum Ownership of Common Stock (as multiple of base salary)** |
| &nbsp;&nbsp;CEO | &nbsp;&nbsp;3x |
| &nbsp;&nbsp;Other Section 16 Officers | &nbsp;&nbsp;1x |

---

Compliance with the minimum share ownership requirement is determined annually as of December 31 each year and commenced December 31, 2025. Individuals who have not yet attained the minimum share ownership requirement must retain 50% of his or her shares acquired upon the (i) vesting of restricted stock or restricted stock units, and (ii) if applicable, the exercise of options, reduced by shares retained or tendered to cover taxes or the exercise price of options. The Company has determined that each of our Section 16 officers were in compliance with the policy as of December 31, 2025.

Qualifying shares that count toward the ownership requirement include:

· Shares owned outright (including shares held through an IRA, 401(k) account, spouse or dependent children, or shares held in trust for the benefit of the owner, his or her spouse, or his or her dependent children);

· Shares underlying equity awards that are deferred shares;

· Shares underlying vested options.

***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 generally denies a federal income tax deduction for compensation exceeding $1,000,000 paid in a taxable year to the Chief Executive Officer, the Chief Financial Officer or any of the three highest compensated officers (other than the Chief Executive Officer and Chief Financial Officer). The Compensation Committee considers the impact of this deductibility limitation on the compensation that it intends to award and may pay compensation that is not 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 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.

***Compensation of Directors***

Prior to January 1, 2025, the Company's fiscal 2025 compensation program for Non-Employee Directors consisted of an annual retainer and restricted stock or restricted stock unit awards. Each Non-Employee Director was entitled to an annual retainer of $45,000 and an annual grant of 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 2019 Plan. The target value of such annual awards was $75,000 for each Non-Employee Director for fiscal 2025. The number of shares underlying such annual awards is calculated based upon the price of the Company's common stock at the close of business on the date of the Company's annual meeting and such shares vest on the first anniversary of the date of grant. 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 the case of restricted stock) or received (in the case of restricted stock units) had no such resignation occurred, based on the number of days served during the applicable calendar year. In addition, all directors are reimbursed for reasonable travel and lodging expenses actually incurred in connection with required attendance at board and committee meetings.

Further, prior to January 1, 2025, the Chairman of the Board received an annual retainer of $30,000 in addition to grants of restricted stock or restricted stock awards. The chairs of the Compensation Committee and Governance Committee each received an annual retainer of $5,000. members of the Nominating and Governance Committee received an additional cash retainer of $3,750, the Chairman of the Audit Committee received an additional cash retainer of $12,000, the Chairman of the Nominating and Governance Committee received an additional cash retainer of $5,000 and the Chairman of the Compensation Committee received an additional cash retainer of $7,500.

On April 17, 2025, the Compensation Committee amended the Company's fiscal 2025 board compensation program. Retroactive to January 1, 2025, each Non-Employee Director is entitled to an annual retainer of $45,000 and an annual grant of restricted stock unit awards with a date of grant target value of $80,000. The grant is made on the date that the Board members are elected or re-elected at the annual meeting and will vest on the one-year anniversary of the date of grant. All cash retainers are paid quarterly in arrears. For Non-Employee Directors elected other than at an annual meeting, both cash retainers and equity grants will be pro-rated for the portion of the year that the Non-Employee Director serves until the next annual meeting.

Additionally, the Chairman of the Board receives an additional cash retainer of $30,000, members of the Audit Committee receive an additional cash retainer of $7,000, members of the Compensation Committee receive an additional annual cash retainer of $5,000, members of the Nominating and Governance Committee receive an additional cash retainer of $3,750, the Chairman of the Audit Committee receives an additional cash retainer of $12,000, the Chairman of the Nominating and Governance Committee receives an additional cash retainer of $5,000 and the Chairman of the Compensation Committee receives an additional cash retainer of $7,500.

In the fiscal years ended September 30, 2025, 2024 and 2023, awards were granted to the Company's non-employee directors under the Company's then-existing equity compensation plans and arrangements with respect to 74,461, 43,986 and 36,182 shares, respectively.

***2019 Stock-Based Incentive Compensation Plan*** 

The 2019 Plan was approved by the Company's shareholders at the Company's Annual Meeting of Shareholders held on April 2, 2019. The 2019 Plan authorizes the grant of stock appreciation rights, restricted stock, options and other equity-based awards. Options granted under the 2019 Plan may be either "incentive stock options" as defined in Section 422 of the U.S. Internal Revenue Code of 1986, as amended (the "Code"), or nonqualified stock options, as determined by 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 2019 Plan is 750,000, plus 139,691 shares of common stock that were authorized but unissued under the Company's 2019 Stock-Based Incentive Compensation Plan as of the effective date of the 2019 Plan (i.e., April 2, 2019), all of which may be issued pursuant to awards of incentive stock options. On April 18, 2024, the Company amended the 2019 Stock-Based Incentive Compensation Plan to include an additional 1,950,000 authorized shares available for issuance. As of September 30, 2025, there were 1,375,682 shares of common stock available for awards under the 2019 Plan.

If any award is forfeited, terminates or otherwise is settled for any reason without an actual distribution of shares to the participant, 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 2019 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 kind of shares of common stock covered by awards then outstanding under the 2019 Plan, the aggregate number and kind of shares of common stock available under the 2019 Plan, any applicable individual limits on the number of shares of common stock available for awards under the 2019 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. In addition, the Compensation Committee may make adjustments in the terms and conditions of any awards, including any performance goals, in recognition of unusual or non-recurring events affecting the Company or any subsidiary, or in response to changes in applicable laws, regulations, or accounting principles.

The 2019 Plan will terminate on April 2, 2029, 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 2019 Plan without shareholder approval, provided that shareholder approval is required for any amendment which (i) would increase the number of shares subject to the 2019 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.

*Audit Fees*

Audit fees for fiscal years 2025 and 2024 were for professional services rendered for the audit of the Company's annual consolidated financial statements, 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 2025 and 2024. Audit-related fees were paid to Grant Thornton during fiscal 2023 for services related to the audit of the required historical financial statements of certain assets acquired from Honeywell International, Inc. during fiscal 2023.

*Tax-Related Fees*

No tax-related fees were paid to Grant Thornton during fiscal years 2025 or 2024.

*All Other Fees*

No other fees were incurred in connection with services provided by Grant Thornton during fiscal years 2025 or 2024.

*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 proposal. Any proposal by the Company's independent registered

[**Table of Contents**](#TOC)

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 Compensation 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 fiscal year 2025 and 2024 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 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.
