Stock Incentive Plan
On October 31, 2014, the Board of Directors approved the Company’s 2014 Omnibus Incentive Plan (the “2014 Plan”).
On June 14, 2022, in connection with the Acquisition, the Board approved the 2014 Amended and Restated Omnibus Incentive Plan (the “2014 Amended and Restated Plan”) which replaced the 2014 Plan in its entirety. The 2014 Amended and Restated Plan, among other things, fixed the number of shares that can be issued under the plan to 91,219,570, provided that each January 1 beginning in 2023 and ending on (and including) January 1, 2032 the number of shares will increase by 5% of the outstanding shares of Common Stock as of the prior December 31, unless the Board of Directors of the Company decides to a lesser increase.
On September 30, 2022, the Amended and Restated 2014 Plan was approved by the shareholders. The 2014 Amended and Restated Plan authorizes the issuance of awards including stock options, stock appreciation rights, restricted stock, stock units and performance units to employees, directors, and consultants of the Company. As of June 30, 2023, the Company had 92,970,517 shares available for future grant under the 2014 Plan.
