Equity Incentive Plan | Note 5 – Equity incentive plan On December 19, 2019, the Company adopted the 2019 Incentive Award Plan (the “2019 Plan”) under which eligible employees, officers, directors and consultants of the Company may be granted incentive or non-qualified stock options, restricted stock, restricted stock units ("RSUs"), or other stock-based awards, including shares of Common Stock. Pursuant to the 2019 Plan, the number of shares of Common Stock available for issuance under the 2019 Plan automatically increases on each January 1 (commencing with January 1, 2021) until and including January 1, 2029, by an amount equal to the lesser of: (a) 5% of the shares of Common Stock outstanding on the final day of the immediately preceding calendar year and (b) such smaller number of shares as is determined by our Board of Directors (the “Board”). The Compensation Committee of the Board approved an increase to the share reserve as set out in the 2019 Plan in the amount of 2,416,007 shares and 2,154,313 shares in April 2023 and April 2024, respectively. As of March 31, 2024, 14,176,685 shares of Common Stock were reserved under the 2019 Plan, of which 2,771,329 shares of Common Stock remained available for issuance. Stock option activity The following table summarizes the Company’s stock option activity under the 2019 Plan:
_______________________________ (1) Aggregate intrinsic value (in thousands) represents the difference between the estimated fair value of the underlying Common Stock and the exercise price of outstanding in-the-money options. The following table summarizes additional information on stock option grants and vesting (in thousands):
Time-based vesting stock options Time-based vesting stock options generally vest over a three-year period, are subject to graded vesting schedules, and expire ten years from the date of grant or within 90 days of termination of employment. No time-based vesting stock options were granted by the Company during the three months ended March 31, 2024 and 2023, respectively.
For the three months ended March 31, 2024 and 2023, the Company recognized $0.7 million and $0.8 million of stock-based compensation expense, respectively, in connection with time-based vesting stock options. As of March 31, 2024 and 2023, there was $1.4 million and $2.4 million of unrecognized stock-based compensation expense, respectively, related to unvested time-based vesting stock options that is expected to be recognized over a weighted-average period of 4.1 and 1.7 years, respectively. Stock Option Valuation The Company uses valuation models to value both time and performance-based vesting stock options. The Company did not grant any time or performance-based vesting stock options during the three months ended March 31, 2024 and 2023, respectively. Stock-based compensation expense Stock-based compensation expense is included in the Company’s Condensed Consolidated Statements of Comprehensive Loss within the following line items (in thousands):
Restricted stock units Periodically, the Company granted RSUs to certain employees which are subject to certain vesting criteria. These RSUs become eligible to begin vesting upon a liquidity event (as defined in the award agreements governing the RSUs). The amount and timing of the vesting of the RSUs depends on the type and timing of the liquidity event as it relates to the Closing Date. Generally, a portion of the RSUs were scheduled to first vest upon the occurrence of the liquidity event and the remainder were scheduled to vest in up to three annual installments thereafter. Because no liquidity event occurred before the third anniversary of the Closing Date, all RSUs are scheduled to vest immediately upon a future liquidity event.
The Company determined the achievement of a liquidity event was not probable and therefore no expense has been recorded related to the RSU awards that vest solely upon a liquidity event.
Performance based restricted stock units
During 2023 and 2022, the Company granted 369,056 and 463,000 performance based RSUs, respectively, to certain employees, 50% of which vest based on the achievement of annual consolidated revenue targets and 50% of which vest based on the achievement of certain annual Nebula revenue targets. These units will vest over three annual installments based on the achievement of the annual consolidated revenue and Nebula revenue performance conditions and are not subject to any liquidity event vesting condition. In the event that the performance conditions are not met in the first or second year, all units granted will vest in the third year if the cumulative performance conditions are met at that time. The grant of awards with performance conditions supports the Company’s goal of aligning executive incentives with long-term stockholder value and ensuring that executive officers have a continuing stake in the long-term success of the Company.
The Company determined the three-year achievement of the overall Company revenue and Nebula revenue targets was probable and incurred $0.4 million and $0.2 million of stock-based compensation expense for the three months ended March 31, 2024 and 2023, respectively, related to the performance-based RSUs granted in 2023 and 2022.
The vesting of the RSUs held by a grantee is generally subject to his or her continued employment with the Company. Time-based restricted stock units The Company grants certain non-employee directors time-based RSUs in satisfaction of their annual retainer payments. These RSUs vest over a one-year or three-year period. During the three months ended March 31, 2024, the Company did not grant any time-based RSUs to its non-employee directors. During the three months ended March 31, 2023, the Company granted 151,515 time-based RSUs to its non-employee directors. During the three months ended March 31, 2024 and 2023, the Company recognized the grant-date fair value of the RSUs granted to non-employee directors of $0.2 million and $0.2 million as stock-based compensation expense, respectively.
The following table summarizes the Company’s RSU activity for performance based RSUs awarded to employees and for time-based RSUs granted to non-employee directors under the 2019 Plan:
