No cash or fractional shares were issued in connection with the Reverse Stock Split, and instead the Company rounded up to the next whole share in lieu of issuing fractional shares that would have been issued in the reverse split. Proportional adjustments were made to the number of shares of Class A Common Stock issuable upon exercise or conversion of the Company’s outstanding stock options and warrants, the exercise price or conversion price (as applicable) of the Company’s outstanding stock options and warrants, and the number of shares reserved for issuance under the Company’s equity incentive plan. All Class A and Class B Common Stock share and per share information included in this Quarterly Report on Form 10-Q has been retroactively adjusted to reflect the impact of the Reverse Stock Split.
