2014 Omnibus Incentive Plan
 
The Company’s 2014 Omnibus Incentive Plan was adopted by the Board of Directors and approved by the shareholders in May 2014, and subsequently amended and restated through May 2025 (as amended and restated, the “2014 Omnibus Plan”). The 2014 Omnibus Plan provides for the grant of stock options, stock appreciation rights, stock awards, cash awards and performance awards to the employees, non-employee directors and consultants of the Company. At December 31, 2025, the number of shares authorized under the 2014 Omnibus Plan was 1,888,997 shares, of which 750,589 were available for future issuance.

Generally, the exercise price of incentive stock options and non-statutory stock options granted under the 2014 Omnibus Plan must be the fair value of the common stock of the Company on the grant date. The term of incentive and non-statutory stock options may not exceed 10 years from the date of grant. A stock option shall be exercisable on or after each vesting date in accordance with the terms set forth in the stock option agreement. The right to exercise a stock option generally vests over three years at a rate of 33% annually or ratably in monthly installments over the vesting period.

Time-based RSUs generally vest over one or 3 years, with 100% or 33% of each award vesting annually, respectively.

Inducement Incentive Plan
 
Under the Company’s Inducement Incentive Plan adopted by the Board of Directors (the “Inducement Plan”), the Company grants time-based RSUs and stock options to recipients thereof as an inducement material to each respective recipient’s entry into employment with the Company in accordance with Nasdaq Listing Rule 5635(c)(4). These inducement awards are subject to such employee’s continued service relationship with the Company, with terms and conditions substantially identical to the terms and conditions of the 2014 Omnibus Plan and the award agreements pursuant to which they were granted. The time-based RSUs and options vest on an annual basis over three years beginning on the anniversary of each individual’s applicable employment commencement date. At December 31, 2025, the number of shares authorized under the Inducement Plan was 254,702 shares, of which 170,723 were available for future issuance.

About Stock Compensation Disclosures

Stock-based compensation disclosures detail the equity awards granted to employees and executives — including stock options, restricted stock units (RSUs), and performance shares — along with the valuation methods and assumptions used to expense them. This section reveals the true cost of talent retention and the alignment between management incentives and shareholder interests.

Key signals: total unrecognized compensation expense and its expected recognition period signal future earnings headwinds from already-granted awards. For stock options, examine Black-Scholes assumptions — expected volatility, risk-free rate, and expected term — as understating any of these reduces reported compensation expense. Compare stock compensation expense as a percentage of revenue against peers to assess dilution cost. Watch vesting schedules for acceleration clauses tied to change-of-control events. Performance-based awards with undemanding targets may indicate weak governance. Add back stock compensation to operating cash flow to calculate a more conservative free cash flow figure.
