[1] As discussed above, certain executives and employees of the Company hold profit interests in Poseidon. The fair value of these profit interests were recorded on the grant dates at fair value utilizing an option-pricing model under which interests are valued by creating a series of call options with exercise prices based on the liquidation preferences and conversion terms of each equity class, adjusted for a discount for the lack of marketability to account for a lack of access to an active public market.

[2] In March 2023, the Company issued warrants to advisors and consultants as discussed below in Note 10, Warrants, which resulted in $0.6 million of stock-based compensation expense in 2023. Refer to discussion below for further detail. Also included in general and administrative expense is the stock-based compensation expense for the options awards to non-employee directors as discussed above.
