14. Net Loss per Share

Net Loss Per Share Attributable to Common Stockholders

Basic net loss per share attributable to common stockholders is calculated by dividing net loss attributable to common stockholders by the weighted-average number of shares issued and shares to be issued under the commitment to issue shares, as these shares are issuable for no consideration.

Diluted net loss per share attributable to common stockholders adjusts the basic net loss per share attributable to common stockholders and the weighted-average number of shares issued and shares to be issued under the commitment to issue shares for potentially dilutive instruments.

For purposes of presentation of basic and diluted net loss per share, the Company includes shares to be issued in the denominator in accordance with ASC 710-10-54-4 and ASC 260-10-45-48 as if they had been issued on the date of the merger, as such shares are non-contingent and are issuable for no consideration (see Note 3, Business Combination).

The net loss per common share was the same for the Class A and Class B Common Stock because they are entitled to the same liquidation and dividend rights and are therefore, combined on the unaudited Condensed Consolidated Statements of Operations and Comprehensive Loss for the three months ended March 31, 2022 and 2021.

Because the Company reported net losses for all periods presented, all potentially dilutive Common Stock equivalents were determined to be antidilutive for those periods and have been excluded from the calculation of net loss per share.

The following table presents the number of anti-dilutive shares excluded from the calculation of diluted net loss per share as of the following dates:

	March 31, 2022		March 31, 2021
Stock-based compensation awards – SI Plan		4,347,492		—
Stock-based compensation awards – EI Plan		30,644,384		31,762,113
Stock-based compensation awards – STI Plan		8,789,939		6,854,436
