Equity Incentive Plans Overview
The Company maintains a long-term incentive plan, the Second Amended and Restated 2018 Equity Incentive Plan (collectively with all amendments referred to as the "2018 Plan"), for employees, non-employee members of its Board of Directors (the "Board"), and consultants. The plan, which is administered by the Board, allows the Company to grant equity-based compensation awards, including stock options, stock appreciation rights, performance share units, restricted stock units, restricted stock awards, common stock warrants, or a combination of awards (collectively, "share-based awards"). The Board also has broad authority to determine the terms and conditions of each option or other kind of equity award, adopt, amend and rescind rules and regulations for the administration of the 2018 Plan and amend or modify outstanding options, grants and awards.
On January 7, 2018, the Board adopted the 2018 Equity Incentive Plan, which was approved by shareholders on April 20, 2018. On February 7, 2020, the Board approved the amendment and restatement of the 2018 Equity Incentive Plan to increase the number of shares issuable thereunder from 2.5 million to 5.0 million, and the amendment was approved by the shareholders on May 11, 2020. On April 22, 2024, the Board approved another amendment to increase the number of shares issuable thereunder from 5.0 million to 6.5 million, which was approved by shareholders on June 20, 2024. As of December 31, 2025, there were 1.2 million shares available for issuance under the 2018 Plan.
No options, stock purchase rights or awards may be made under the 2018 Plan on or after the ten-year anniversary of the adoption of the 2018 Plan by the Board, but the 2018 Plan will continue thereafter while previously granted options, stock appreciation rights or awards remain subject to the 2018 Plan. Options granted under the 2018 Plan may be either "incentive stock options" that are intended to meet the requirements of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code") or "non-statutory stock options" that do not meet the requirements of Section 422 of the Code. The Board will determine the exercise price of options granted under the 2018 Plan. The exercise price of stock options may not be less than the fair market value, on the date of grant, per share of the Company's common stock issuable upon exercise of the option (or 110% of fair market value in the case of incentive options granted to a 10% stockholder). No option may be exercisable for more than ten years (five years in the case of an incentive stock option granted to a 10% stockholder) from the date of grant.
Share-Based Compensation

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.
