Stock-based Compensation
2018 Equity Incentive Plan
The 2018 Plan was approved by the Company's Board of Directors and shareholders in July 2018. The 2018 Plan provided for the issuance of up to 6,685,696 of the Company's Common Stock, and these shares were registered on a Form S-8 during 2018. Under the 2018 Plan, the Company's compensation committee may grant awards of non-qualified stock options, incentive stock options, SARs, restricted stock awards, RSUs, other stock-based awards (including cash bonus awards) or any combination of the foregoing. Any current or prospective employees, officers, consultants or advisors that the Company's compensation committee (or, in the case of non-employee directors, the Company's Board of Directors) selects, from time to time, are eligible to receive awards under the 2018 Plan. If any award granted under the 2018 Plan expires, terminates, or is canceled or forfeited without being settled or exercised, or if a SAR is settled in cash or otherwise without the issuance of shares, shares of the Company's Common Stock subject to such award will again be made available for future grants. In addition, if any shares are surrendered or tendered to pay the exercise price of an award or to satisfy withholding taxes owed, such shares will again be available for grants under the 2018 Plan. On March 17, 2022, the Company's Board of Directors unanimously approved an amendment to the 2018 Plan which was subsequently approved by our shareholders, to increase the number of shares authorized for issuance under the plan by 2,500,000 shares, resulting in 9,185,696 shares of the Company's Common Stock authorized for issuance under the plan. These additional shares were registered on Form S-8 in December 2022.
