In 2025, our Named Executive Officers and their positions were as follows:

  • Daniel Reis-Faria, our Chief Executive Officer;

  • Michael Heinrich, our Executive Chairman;

Narrative to the Summary Compensation Table

Base Salaries

We use base salaries to recognize the experience, skills, knowledge, and responsibilities required of all our employees, including our Named Executive Officers. Base salaries are reviewed annually, typically in connection with our annual performance review process, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance, and experience.

Annual Bonus/Non-Equity Incentive Plan Compensation

For 2025 and 2024, our Named Executive Officers were eligible to earn a cash bonus under the Company's annual bonus program based upon achievement of both corporate and individual goals determined by the Board based on a target percentage of annual base salary. For 2025, Mr. Reis-Faria earned a signing bonus of $250,000 and Mr. Heinrich received a signing bonus of $250,000. For 2024, Mr. Starke received a cash bonus of $36,000 and Mr. Vaiman received a cash bonus of $18,000.

Equity-Based Compensation

Certain of the Company's Named Executive Officers received grants of stock appreciation rights and grants of restricted Common Shares under the Company's option plan and 2022 Plan during 2024 and 2025.

Company Stock Option Plan

The Company has a stock option plan whereby it may grant options for the purchase of Common Shares to any director, consultant, employee or officer of the Company or its subsidiaries. The aggregate number of shares that may be issuable pursuant to options granted under the Company's stock option plan will not exceed 10% of fully diluted Common Shares of the Company. The options are non-transferable and non-assignable and may be granted for a term not exceeding five to ten years. The exercise price of the options is determined by the Board at the time of grant, but in the event that the Common Shares are traded on any stock exchange, may not be less than the closing price of such shares on such exchange on the trading date immediately precedent the date of grant, subject to all applicable regulatory requirements.

2022 Plan

The 2022 Plan was adopted by the Company following shareholder approval at the Company's 2022 annual meeting (the "Shareholder Approval Date") and amended at the Company's 2023 and 2024 annual meetings, as well as the 2025 special meeting.

The purpose of the 2022 Plan is to assist the Company and its subsidiaries and other designated affiliates, which we refer to herein as "Related Entities", in attracting, motivating, retaining and rewarding high-quality executives and other employees, officers, directors consultants and other persons who provide services to the Company or its Related Entities, by enabling such persons to acquire or increase a proprietary interest in the Company in order to strengthen the mutuality of interests between such persons and the Company's shareholders, and providing such persons with performance incentives to expend their maximum efforts in the creation of shareholder value.

Shares Available for Awards

Under the 2022 Plan, the total number of Common Shares reserved and available for delivery under the 2022 Plan ("Awards") at any time during the term of the Plan shall be equal to 1,506,892 Common Shares. Awards issued in substitution for awards previously granted by a company acquired by the Company or a Related Entity, or with which the Company or any Related Entity combines, do not reduce the limit on grants of Awards under the 2022 Plan. The maximum aggregate number of Common Shares that may be delivered under the 2022 Plan as a result of the exercise of stock options shall be 847,843 Common Shares.

Subject to adjustment as provided in the 2022 Plan, in any fiscal year of the Company during any part of which the 2022 Plan is in effect, no participant who is a member of the Board but is not also an employee or consultant to the Company or Related Entity may be granted any Awards that have a "fair value" as of the date of grant, as determined in accordance with FASB ASC Topic 718 (or any other applicable accounting guidance) that exceeds $250,000 in the aggregate.

The committee designated and empowered by the Board to administer the 2022 Plan ("Committee") is authorized to adjust the limitations described in the preceding paragraph and is authorized to adjust outstanding Awards (including adjustments to exercise prices of stock options and other affected terms of Awards) in the event that a dividend or other distribution (whether in cash, Common Share or other property), recapitalization, forward or reverse split, reorganization, merger, consolidation, spin-off, combination, repurchase, share exchange or other similar corporate transaction or event affects the Common Shares so that an adjustment is appropriate. The Committee is also authorized to adjust performance conditions and other terms of Awards in response to these kinds of events or in response to changes in applicable laws, regulations or accounting principles.

Eligibility

The persons eligible to receive Awards under the 2022 Plan are the officers, directors, employees, consultants and other persons who provide services to the Company or any Related Entity. The foregoing notwithstanding, only employees of the Company, or any parent corporation or subsidiary company of the Company (as those terms are defined in Sections 424(e) and (f) of the Internal Revenue Code of 1986, as amended (the "Code"), respectively), are eligible for purposes of receiving any incentive stock options ("ISOs"). An employee on leave of absence may be considered as still in the employ of the Company or a Related Entity for purposes of eligibility for participation in the 2022 Plan.

Administration

The 2022 Plan is to be administered by the Committee; provided, however, that except as otherwise expressly provided in the 2022 Plan, the Board may exercise any power or authority granted to the Committee under the 2022 Plan. Subject to the terms of the 2022 Plan, the Committee is authorized to select eligible persons to receive Awards, determine the type, number and other terms and conditions of, and all other matters relating to, Awards, prescribe Award agreements (which need not be identical for each person who has been granted an Award under the 2022 Plan which remains outstanding (a "Participant")), and the rules and regulations for the administration of the 2022 Plan, construe and interpret the 2022 Plan and Award agreements, correct defects, supply omissions or reconcile inconsistencies therein, and make all other decisions and determinations as the Committee may deem necessary or advisable for the administration of the 2022 Plan.

Stock Options and Stock Appreciation Rights

The Committee is authorized to grant stock options, including both ISOs, which can result in potentially favorable tax treatment to the participant, and non-qualified stock options, and stock appreciation rights entitling the participant to receive the amount by which the fair market value of a Common Share on the date of exercise exceeds the grant price of the stock appreciation right. The exercise price per share subject to an option and the grant price of a stock appreciation right are determined by the Committee but may not be less than 100% of the fair market value of a Common Share on the date the award is granted. An option granted to a person who owns or is deemed to own stock representing 10% or more of the voting power of all classes of stock of the Company or any parent company (sometimes referred to as a "10% owner") will not qualify as an ISO unless the exercise price for the option is not less than 110% of the fair market value of a Common Share on the date such ISO is granted.

For purposes of the 2022 Plan, the term "fair market value" means the fair market value of Common Shares, Awards or other property as determined by the Committee or under procedures established by the Committee. Unless otherwise determined by the Committee, the fair market value of a Common Share as of any given date shall be the closing price of a Common Share on the business day that immediately precedes the date as of which the value is being determined as quoted on the Nasdaq or such other national or regional securities exchange or market system constituting the primary market on which a Common Share is traded, as reported in The Wall Street Journal or such other source as the Company deems reliable or, if there is no sale on that date, then on the last previous day on which a sale was reported. The maximum term of each option or stock appreciation right, the times at which each option or stock appreciation right will be exercisable, and provisions requiring forfeiture of unexercised options or stock appreciation rights at or following termination of employment, generally are fixed by the Committee, except that no option or stock appreciation right may have a term exceeding ten years, and no ISO granted to a 10% shareholder (as described above) may have a term exceeding five years (to the extent required by the Code at the time of grant). Methods of exercise and settlement and other terms of options and stock appreciation rights are determined by the Committee. The Committee thus may permit the exercise price of options awarded under the 2022 Plan to be paid in cash, shares, other Awards or other property (including loans to participants).

Restricted Stock and Restricted Stock Units

The Committee is authorized to grant restricted stock and restricted stock units. Restricted stock is a grant of Common Shares which may not be sold or disposed of, and which is subject to such risks of forfeiture and other restrictions as the Committee may impose. A participant granted restricted stock generally has all of the rights of a shareholder of the Company, unless otherwise determined by the Committee. An Award of restricted stock units confers upon a participant the right to receive Common Shares at the end of a specified deferral period, subject to such risks of forfeiture and other restrictions as the Committee may impose. Prior to settlement, an Award of restricted stock units carries no voting or dividend rights, or other rights associated with share ownership, although dividend equivalents may be granted, as discussed below.

Dividend Equivalents

The Committee is authorized to grant dividend equivalents conferring on participants the right to receive, currently or on a deferred basis, cash, Common Shares, other Awards or other property equal in value to dividends paid on a specific number of Common Shares or other periodic payments. Dividend equivalents may be granted alone or in connection with another Award, may be paid currently or on a deferred basis and, if deferred, may be deemed to have been reinvested in additional Common Shares, Awards or otherwise as specified by the Committee.

Bonus Stock and Awards in Lieu of Cash Obligations

The Committee is authorized to grant Common Shares as a bonus free of restrictions, or to grant Common Shares or other Awards in lieu of Company obligations to pay cash under the 2022 Plan or other plans or compensatory arrangements, subject to such terms as the Committee may specify.

Other Stock-Based Awards

The Committee or the Board is authorized to grant Awards that are denominated or payable in, valued by reference to, or otherwise based on or related to Common Shares. The Committee determines the terms and conditions of such Awards.

Performance Awards

The Committee is authorized to grant performance awards to participants on terms and conditions established by the Committee. The performance criteria to be achieved during any performance period and the length of the performance period is determined by the Committee upon the grant of the performance award. Performance awards may be valued by reference to a designated number of Common Shares or by reference to a designated amount of property including cash. Performance awards may be settled by delivery of cash, Common Shares or other property, or any combination thereof, as determined by the Committee.

Other Terms of Awards

Awards may be settled in the form of cash, Common Shares, other Awards or other property, in the discretion of the Committee. The Committee may require or permit participants to defer the settlement of all or part of an Award in accordance with such terms and conditions as the Committee may establish, including payment or crediting of interest or dividend equivalents on deferred amounts, and the crediting of earnings, gains and losses based on deemed investment of deferred amounts in specified investment vehicles. The Committee is authorized to place cash, Common Shares or other property in trusts or make other arrangements to provide for payment of the Company's obligations under the 2022 Plan. The Committee may condition any payment relating to an Award on the withholding of taxes and may provide that a portion of any Common Shares or other property to be distributed will be withheld (or previously acquired Common Shares or other property be surrendered by the participant) to satisfy withholding and other tax obligations. Awards granted under the 2022 Plan generally may not be pledged or otherwise encumbered and are not transferable except by will or by the laws of descent and distribution, or to a designated beneficiary upon the participant's death, except that the Committee may, in its discretion, permit transfers subject to any terms and conditions the Committee may impose thereon.

Awards under the 2022 Plan are generally granted without a requirement that the participant pay consideration in the form of cash or property for the grant (as distinguished from the exercise), except to the extent required by law. The Committee may, however, grant Awards in exchange for other Awards under the 2022 Plan, awards under other Company plans, or other rights to payment from the Company, and may grant Awards in addition to and in tandem with such other Awards, rights or other awards.

Acceleration of Vesting; Change in Control

The Committee may, in its discretion, accelerate the exercisability, the lapsing of restrictions or the expiration of deferral or vesting periods of any Award, and such accelerated exercisability, lapse, expiration and if so provided in the Award agreement or otherwise determined by the Committee, vesting shall occur automatically in the case of a "change in control" of the Company, as defined in the 2022 Plan (including the cash settlement of stock appreciation rights which may be exercisable in the event of a change in control). In addition, the Committee may provide in an Award agreement that the performance goals relating to any performance award will be deemed to have been met upon the occurrence of any "change in control."

Amendment and Termination

The Board may amend, alter, suspend, discontinue or terminate the 2022 Plan or the Committee's authority to grant Awards without further shareholder approval, except that shareholder approval must be obtained for any amendment or alteration if such approval is required by law or regulation or under the rules of any stock exchange or quotation system on which Common Shares are then listed or quoted. Thus, shareholder approval may not necessarily be required for every amendment to the 2022 Plan which might increase the cost of the 2022 Plan or alter the eligibility of persons to receive Awards. Shareholder approval will not be deemed to be required under laws or regulations, such as those relating to ISOs, that condition favorable treatment of participants on such approval, although the Board may, in its discretion, seek shareholder approval in any circumstance in which it deems such approval advisable. Unless earlier terminated by the Board, the 2022 Plan will terminate at the earliest of (a) such time as no Common Shares remain available for issuance under the 2022 Plan, (b) termination of the 2022 Plan by the Board, or (c) the tenth anniversary of the Shareholder Approval Date. Awards outstanding upon expiration of the 2022 Plan shall remain in effect until they have been exercised or terminated or have expired.

Hedging and Pledging Company Securities

Our Insider Trading Policy prohibits ourdirectors, officers, employees, family members of such persons and entities controlled by such persons from engaging in hedging, short sales, or trading in publicly traded put or call options with respect to our securities. Additionally, policy prohibits the same persons from purchasing our securities on margin, borrowing against any account in which our securities are held, or pledging our securities as collateral for a loan.

Clawback Policy

Effective as of October 2, 2023, we adopted a clawback policy that provides for the recoupment of excess incentive compensation paid to executive officers, including the Named Executive Officers, in accordance with Nasdaq listing standards and Exchange Act Rule 10D-1. The policy applies to compensation that is granted, earned, or vested based in whole or in part upon the attainment of a financial reporting measure and provides for the reimbursement or forfeiture by the executive officer of the excess portion of the compensation received by the executive officers during the three preceding fiscal years.

Compensation-Related Risk Assessment

Our Compensation Committee assesses and monitors whether any of our compensation policies and programs is reasonably likely to have a material adverse effect on our Company. The Compensation Committee and management do not believe that the Company presently maintains compensation policies or practices that are reasonably likely to have a material adverse effect on the Company's risk management or create incentives that could lead to excessive or inappropriate risk taking by employees. In reaching this conclusion, the Compensation Committee considered all components of our compensation program and assessed any associated risks. The Compensation Committee also considered the various strategies and measures employed by the Company that mitigate such risk, including: (i) the overall balance achieved through our use of a mix of cash and equity, annual and long-term incentives and time-and performance-based compensation; (ii) our use of multi-year vesting periods for equity grants; and (ii) the oversight exercised by the Compensation Committee over the performance metrics and results under the Stock Option Plan and the 2022 Plan.
