Share-Based Compensation
In 2010, the Company adopted the 2010 Equity Incentive Plan (the “2010 Plan”), which provides for the grant of restricted stock awards, stock options, and other share-based awards to employees, consultants, and directors. In November 2020, the Company’s Board of Directors extended the term of the 2010 Plan to July 1, 2021. In 2021, the Company adopted the 2020 Equity Incentive Plan (the “2020 Plan”), which provides for the grant of restricted stock awards, incentive and non-statutory stock options, and other share-based awards to employees, consultants, and directors. In June 2023, the 2020 Plan was amended, as approved by shareholders, to increase the common shares reserved for issuance under the plan by 10,000 shares. As of December 31, 2024, there is an aggregate of 63,497 common shares reserved for issuance under the 2020 Plan and may reset on January 1 of each year, based on a formula set forth in the Equity Incentive Plan. All options granted to date have a ten year contractual life and vesting terms of four years. In general, vested options expire if not exercised 90 days after termination of service. Forfeitures are accounted for as they occur. As of December 31, 2024, a total of 55,398 shares of common stock remained available for future issuance under the 2020 Plan.

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.
