Note 10 – Net Loss Per Share Attributable to Common Stockholders

Basic loss per share is computed by dividing net loss attributable to Common Stockholders by the weighted-average number of shares of Common Stock outstanding during the period without consideration for Common Stock equivalents.

Diluted net loss per share attributable to Common Stockholders is computed by dividing net loss by the weighted-average number of shares of Common Stock outstanding during the period and potentially dilutive Common Stock equivalents, including stock options,RSUs, warrants to purchase Senior Preferred Stock, Prime Preferred Stock, and Prior Preferred Stock, shares of Senior Preferred Stock, Prime Preferred Stock, and Prior Preferred Stock, and Founders Preferred Stock, except in cases where the effect of the Common Stock equivalent would be antidilutive. Potential Common Stock equivalents consist of Common Stock issuable upon exercise of stock options and vesting of RSUs using the treasury stock method. Since the Company was in a loss position during the nine months ended September 30, 2021 and 2020, respectively, basic and diluted earnings per share are the same as the effect of the conversion of Redeemable Convertible Preferred Stock and assumed exercise of warrants, stock options, and vesting of RSUs, which is anti-dilutive.

The following table presents the calculation of basic and diluted net loss per share attributable to Common Stockholders (in thousands, except per share amounts):

The following outstanding securities were excluded from the computation of diluted net loss per share because their effect would have been anti-dilutive for the periods presented (in thousands):
