On June 18, 2020, the Company issued a press release announcing that it will voluntarily delist its currently issued and outstanding ION Units (as defined herein) from The New York Stock Exchange (“NYSE”). As previously disclosed, on January 25, 2021, ION Acquisition Corp. 1 Ltd., a Cayman Islands exempted company (“Company”), entered into an Agreement and Plan of Merger (as amended on April 27, 2021, the “Merger Agreement”) by and among the Company, Taboola.com Ltd., a company organized under the laws of the State of Israel (“Taboola”), and Toronto Sub Ltd., a Cayman Islands exempted company and a direct, wholly-owned subsidiary of Taboola (“Merger Sub”). Subject to the terms and conditions of the Merger Agreement, Merger Sub will merge with and into the Company (the “Merger”), with the Company continuing as the surviving company after the Merger. As a result of the Merger and the other transactions contemplated by the Merger Agreement (the “Business Combination”), the Company will become a direct, wholly-owned subsidiary of Taboola.

Pursuant to the Merger Agreement, at the effective time of the Business Combination (the “Effective Time”), (a) each issued and outstanding unit of the Company (an “ION Unit”), consisting of one Class A ordinary share, par value $0.0001 per share, of the Company (the “Class A Ordinary Shares”) and one-fifth of one warrant of the Company entitling the holder to purchase one Class A Ordinary Share per warrant at a price of $11.50 per share (“ION Warrants”), will be automatically separated and the holder thereof will be deemed to hold one Class A Ordinary Share and one-fifth of one ION Warrant, (b) each Class A Ordinary Share outstanding immediately prior to the Effective Time will be exchanged for one ordinary share no par value per share of Taboola (the “Taboola Ordinary Shares”), (c) each Class B ordinary shares, par value $0.0001 per share, of the Company (the “Class B Ordinary Shares” and, together with Class A Ordinary Shares, the “ION Ordinary Shares”), outstanding immediately prior to the Effective Time, will be exchanged for one Taboola Ordinary Share and (d) each ION Warrant outstanding immediately prior to the Effective Time, will be assumed by Taboola and will become a warrant of Taboola (the “Taboola Warrants”).

On June 18, 2020, the Company notified the NYSE that, subject to approval by the NASDAQ Stock Market LLC (“NASDAQ”) of Taboola’s listing application and satisfaction of the other conditions to the closing of the Merger, following the Merger, the Company intends to voluntarily delist its currently issued and outstanding ION Units from the NYSE. The Board of Directors of the Company previously approved such delisting from NYSE, effective upon closing of the Merger. The Company anticipates that a Form 25 with respect to the delisting of the ION Units from the NYSE will be filed with the SEC on or about June 28, 2021.

The Company and Taboola currently expect to commence trading of the Taboola Ordinary Shares and Taboola Warrants on NASDAQ under the ticker symbols “TBLA” and “TBLAW,” respectively, on the trading day following the closing of the Merger. The ION Units will continue to trade on the NYSE under the ticker symbols “IACA.UN,” “IACA” and “IACA.WT” until the Merger and subsequent transfer is complete.

A copy of the press release is furnished hereto as Exhibit 99.1.

Most of these factors are outside the Company’s and Taboola’s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement or could otherwise cause the Business Combination to fail to close; (2) the outcome of legal proceedings that have or may be instituted against the Company and Taboola; (3) the inability to complete the Business Combination, including due to failure to obtain the requisite approval of shareholders or to satisfy the other conditions to closing in the Merger Agreement; (4) the receipt of an unsolicited offer from another party for an alternative business transaction that could interfere with the Business Combination; (5) the inability to obtain or maintain the listing of the ordinary shares of the post-acquisition company on The New York Stock Exchange or the Nasdaq Capital Market, as applicable, following the Business Combination; (6) the risk that the announcement and consummation of the Business Combination disrupts current plans and operations; (7) the ability to recognize the anticipated benefits of the Business Combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably and retain its key employees; (8) costs related to the Business Combination; (9) changes in applicable laws or regulations; (10) the possibility that Taboola or the combined company may be adversely affected by other economic, business, competitive and/or factors such as the COVID-19 pandemic; and (11) other risks and uncertainties indicated from time to time in the proxy statement/prospectus relating to the Business Combination, including those under “Risk Factors” in the Registration Statement, and in the Company’s other filings with the SEC. The Company cautions that the foregoing list of factors is not exclusive. The Company cautions readers not to place undue reliance upon any forward-looking statements, which speak only as of the date made. The Company does not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in its expectations or any change in events, conditions or circumstances on which any such statement is based.
