Basis of Presentation— The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”). We believe the disclosures made are adequate to make the information presented not misleading. However, the accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes contained in our Annual Report on Form 10-K for the year ended December 31, 2023 (“2023 Annual Report”). Our condensed consolidated financial statements include the accounts of Katapult Holdings, Inc. and its wholly owned subsidiaries. In the opinion of management, all adjustments, of a normal recurring nature, considered necessary for a fair presentation have been included in these condensed consolidated financial statements. All intercompany balances and transactions have been eliminated in consolidation. Reverse Stock Split— On July 27, 2023, the Company amended the Second Amended and Restated Certificate of Incorporation to effect, effective as of July 27, 2023, the Reverse Stock Split of our Common Stock. At the effective time of the Reverse Stock Split, every twenty-five shares of our Common Stock either issued and outstanding or held as treasury stock were automatically reclassified into one new share of our Common Stock. The Reverse Stock Split was approved by the Company’s stockholders at the Annual Meeting of Stockholders on June 6, 2023 and approved by the Board of Directors on July 11, 2023. The common stock began trading on Nasdaq on a reverse split-adjusted basis on July 28, 2023 under the existing trading symbol “KPLT.” As a result of the Reverse Stock Split, proportionate adjustments were made to the number of shares of Common Stock underlying the Company’s outstanding equity awards and the number of shares issuable under our equity incentive plans and certain existing agreements, as well as the exercise, grant and acquisition prices of such equity awards, as applicable. In addition, proportionate adjustments were made to the Company’s outstanding warrants, resulting in: (i) each publicly traded warrant issued under the Warrant Agreement, dated October 31, 2019, exercisable for 1/25th of a share of Common Stock at an exercise price of $287.50 per whole share; and (ii) the warrant under the Warrant to Purchase Stock, dated March 6, 2023, issued by Katapult to Midtown Madison Management LLC, exercisable for up to 160,000 shares of Common Stock at an exercise price of $0.25 per share. No fractional shares were issued in connection with the Reverse Stock Split. Stockholders who were entitled to receive fractional shares as a result of the Reverse Stock Split received one full share of post-Reverse Stock Split Common Stock, in lieu of receiving such fractional shares. The effects of the Reverse Stock Split have been reflected in our condensed consolidated financial statements for all periods presented.
