The Registration Statement includes two prospectuses: (i) a base prospectus (the “Base Prospectus”) covering the Shelf Securities and (ii) a sales agreement prospectus supplement (the “Sales Agreement Prospectus Supplement”), covering the offering from time to time, pursuant to Rule 415 under the Securities Act, by the Company of $22,800,000 of shares of its class A common stock, par value $0.0001 per share, that may be issued and sold pursuant to the At Market Issuance Sales Agreement dated as of September 19, 2022, among the Company, B. Riley Securities, Inc. and Northland Securities, Inc.
