Flybondi Highlights

Transaction Overview

The planned transaction, structured as a share exchange and a subsidiary merger (the “Business Combination”), has been approved by the boards of directors of both Integral 1 and Flybondi, and is expected to close during the first half of 2024, subject to regulatory approvals, the approval by the stockholders of Integral 1 and the shareholders of Flybondi, and the satisfaction of certain other customary closing conditions, including the review by the U.S. Securities and Exchange Commission (“SEC”) of the proxy statement/prospectus relating to the proposed Business Combination and the listing approval by Nasdaq.

Upon the closing of the proposed Business Combination, the combined company will continue to operate under the Flybondi name, and Flybondi’s executive management team will continue to lead the combined company. All cash remaining on the combined company’s balance sheet at the closing of the Business Combination, after the settlement of transaction-related expenses, is expected to be utilized by the combined company for working capital, growth, and other general corporate purposes.

An affiliate of Flybondi recently formed FB Parent Limited, a limited company incorporated under the laws of England and Wales (“FB Parent”), which in turn formed (i) Gaucho MS, Inc., a Delaware corporation (“Merger Sub”), as its wholly-owned subsidiary. Pursuant to the transactions contemplated by the business combination agreement, (i) FB Parent shall acquire the outstanding shares of Flybondi from Flybondi’s shareholders party to the business combination agreement, in exchange for ordinary shares of FB Parent and (ii) Merger Sub will merge with and into Integral 1, with Integral 1 continuing as the surviving entity and as a wholly-owned subsidiary of FB Parent.
