[1] Prior period results have been adjusted to reflect the exchange of Legacy MoneyLion’s common stock for MoneyLion Class A Common Stock at an exchange ratio of approximately 16.4078 in September 2021 as a result of the Business Combination. See Note 4, “Business combination,” for details. Because the Company had a net loss in the nine months ended September 30, 2021 and the three and nine months ended September 30, 2020, the Company’s potentially dilutive securities, which include stock options, restricted stock, preferred stock and warrants to purchase shares of common stock and preferred stock, have been excluded from the computation of diluted net loss per share for those periods, as the effect would be anti-dilutive. Therefore, the weighted-average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders for these periods is the same.  See Note 17, “Net income (loss) per share (as restated)” for a reconciliation of Net income per share, diluted for the three months ended September 30, 2021.
