Stock compensation plans

2017 Plan

On January 9, 2017, the Company’s board of directors adopted the 2017 Stock Incentive Plan (the “2017 Plan”). The Plan offered employees, directors and selected service providers the opportunity to acquire equity in the Company through grants of options, restricted stock awards, stock appreciation rights, restricted stock units (“RSUs”), and other stock awards, at exercise prices, if applicable, not less than the fair market value of the Company's common stock on the date of grant.

On July 1, 2022, we filed a registration statement on Form S-8 to register 500,000 (on a post-split basis) shares of common stock for issuance upon the settlement of RSUs and the exercise of stock options previously granted under the 2017 Plan that remain outstanding. Since April 27, 2021, no new awards have been or will be granted under the 2017 Plan.

2021 Plan

Our 2021 Stock Incentive Plan (the "2021 Plan"), which was adopted by our Board of Directors and approved by our stockholders on April 16, 2021, and became effective on April 27, 2021, provides for the grant of awards similar to the 2017 Plan, as well as stock bonuses and cash awards. The number of shares initially reserved for issuance under the 2021 Plan was 1,264,524 (on a post-split basis), which automatically increases on January 1 of each calendar year prior to the tenth anniversary of the Plan's effective date in an amount equal to the lesser of (i) 4% of the total number of shares of common stock outstanding on the day prior (December 31st), and (ii) a number of shares of common stock determined by the compensation committee of the Company's board of directors.

In addition, on September 19, 2025, we filed a registration statement on Form S-8 to register an additional 2,000,000 shares of our common stock issuable under the 2021 Plan. The additional shares were approved during a Special Meeting of Stockholders held on September 4, 2025.

Through December 31, 2025, an additional 1,806,544 shares (on a post-split basis) became available for issuance pursuant to the automatic increase provisions of the 2021 Plan and the additional shares approved by stockholders, as described above, resulting in a total number of shares authorized for issuance under the 2021 Plan of 5,071,068 (on a post-split basis).

Employment Inducement Awards

On August 16, 2024, we filed a registration statement on Form S-8 to register an additional 650,000 shares (on a post-split basis) of common stock for issuance upon the vesting and settlement of time-based RSUs, in accordance with the terms of the Restricted Stock Unit Inducement Award Agreement, by and between the Company and Yann Brandt and the vesting and settlement of performance-based RSUs, in accordance with the terms of the Share Target Restricted Stock Unit Inducement Award Agreement by and between the Company and Yann Brandt (collectively, the "Employment Inducement Awards"). The Employment Inducement Awards were granted effective August 19, 2024, in connection with Mr. Brandt's commencement of employment as our President and Chief Executive Officer.

2021 ESPP Plan

Concurrent with the adoption of the 2021 Plan, we also adopted the 2021 Employee Stock Purchase Plan (the "2021 ESPP Plan") in order to provide employees of the Company and its designated subsidiaries with an opportunity to purchase the Company's common stock through accumulated payroll deductions at 85% of the stock's fair market value. As of December 31, 2025, this plan has not yet been implemented internally within the Company, and no purchases of common stock have been made pursuant to the 2021 ESPP Plan.

Information on outstanding awards

Stock options generally vest between two and four years from the date of grant, and, for those remaining outstanding as of December 31, 2025, have only service-based vesting conditions.

RSU grants may contain either (i) service-based vesting conditions or (ii) a combination of market or performance and service-based vesting conditions, which must be met in order to vest. Awards with service-based vesting conditions generally vest over a period of three to four years from the date of grant. Awards with market or performance-based vesting conditions will generally vest upon achievement of the related targets, providing the employee continues to be employed at the date of vesting. Performance conditions in certain of our outstanding awards are based on the recipient achieving specified sales metrics whereas, market conditions in certain outstanding awards are based on the closing price of our common stock achieving specified levels for a period of time.

Generally, new shares of authorized common stock are issued to satisfy vesting or exercise of outstanding awards under both the 2017 and 2021 Stock Incentive Plans, although treasury shares are also available for issuance at our discretion.

The weighted average grant date fair value of RSUs granted during the year ended December 31, 2024 was $2.62 per RSU (on a post-split basis). The total fair value of RSUs vested was approximately $3.8 million and $8.8 million during the years ended December 31, 2025 and 2024, respectively.

Other employee benefit plans

We sponsor a 401(k) savings plan for our U.S. employees, whereby the employees can elect to make pre- or post-tax contributions, subject to certain limitations. We make matching contributions equal to 100% of the first 3% and 50% of the next 2% of an employee's contribution. Employee and company contributions are both immediately vested. Company matching contributions were approximately $0.4 million and $0.5 million for the years ending December 31, 2025 and 2024, respectively.

Employees are also eligible to participate in various employee welfare benefit plans, including medical, dental, vision, prescription and life insurance, in which the Company pays a portion of the cost. All such plans are unfunded.
