Item 8.01 Other Events

As previously disclosed, on July 18, 2021, Investindustrial Acquisition Corp, a Cayman Islands exempted company (“IIAC”), entered into a Business Combination Agreement (as it may be amended, supplemented or otherwise modified from time to time, the “Business Combination Agreement”), by and among IIAC, Ermenegildo Zegna Holditalia SpA, a joint stock company incorporated under Italian law (“Zegna”), and EZ Cayman, a Cayman Islands exempted company (“Merger Sub”). A copy of the Business Combination Agreement was attached as Exhibit 2.1 to IIAC’s Current Report on Form 8-K, filed with the Securities and Exchange Commission (“SEC”) on July 19, 2021.

Following the entry into the Business Combination Agreement, IIAC received three letters (collectively, the “Shareholder Letters”) from purported shareholders of IIAC claiming certain allegedly material omissions in its preliminary proxy statement/prospectus (as amended, the “Proxy Statement”), which was included in the registration statement on Form F-4 first filed with the Securities Exchange Commission by Zegna on August 27, 2021 relating to the transactions contemplated by the Business Combination Agreement (together, the “Business Combination”).

While IIAC believes that the disclosures set forth in the Proxy Statement comply fully with applicable law, in order to moot the plaintiff’s disclosure claims in the Shareholder Letters, to avoid nuisance, cost and distraction, and to preclude any efforts to delay the closing of the Business Combination, IIAC has determined to voluntarily supplement the Proxy Statement with the supplemental disclosures set forth below (the “Supplemental Disclosures”). Nothing in the Supplemental Disclosures shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, IIAC specifically denies all allegations in the Shareholder Letters that any additional disclosure was or is required. IIAC believes the Shareholder Letters are without merit.

Supplemental Disclosures to Proxy Statement

The following supplemental information should be read in conjunction with the Proxy Statement, which should be read in its entirety. All page references are to pages in the Proxy Statement, and terms used below, unless otherwise defined, have the meanings set forth in the Proxy Statement. Underlined text shows text being added to a referenced disclosure in the Proxy Statement.

The following disclosure should be added to the end of the second paragraph on page 119 of the Proxy Statement under the heading “Background to the Business Combination”:

“None of the confidentiality agreements IIAC entered into with potential target companies contained standstill provisions or “don’t-ask-don’t-waive” provisions.”

The following disclosure should be added to the end of the fourth full paragraph on page 121 of the Proxy Statement under the heading “Background to the Business Combination”:

“The executed Term Sheet provided that (i) subject to the Minimum Holding Requirement, IIAC Sponsor would have the right to nominate one director for election to the Zegna Board, which nominee would be Mr. Andrea C. Bonomi, and that any replacement nominee would be subject to the approval of the Zegna Board in its discretion and (ii) the parties intended that Mr. Sergio P. Ermotti would be nominated for election to the Zegna Board.”

The following disclosure should be added to page 307 of the Proxy Statement at the end of the paragraph under the heading “Initial Business Combination”:

As of July 18, 2021, the date of execution of the Business Combination Agreement, the proceeds in the Trust Account were equal to approximately $402.5 million. Based on the financial analysis of Zegna generally used by IIAC in evaluating the Zegna business and provided to the IIAC Board in connection with the Business Combination, as well as the expected initial enterprise value of approximately $3.1 billion for the post-closing company implied by the terms of the Business Combination Agreement, which amount was negotiated on an arms’-length basis and agreed to after taking into consideration various factors, including certain unaudited prospective financial information for Zegna and discussions with Zegna management regarding the future growth and outlook for the business, the IIAC Board determined that the 80% valuation requirement was met.

Additional Information

In connection with the Business Combination, Zegna has filed a registration statement on Form F-4 (File No. 333-259139) with the Securities and Exchange Commission (the “SEC”) (the “Registration Statement”) that includes a prospectus with respect to Zegna’s securities to be issued in connection with the transactions contemplated by the Business Combination Agreement and a proxy statement with respect to the shareholder meeting of IIAC to vote on the Business Combination. The Registration Statement has been declared effective by the SEC and and IIAC’s proxy statement has been mailed to IIAC’s shareholders. Shareholders of IIAC and other interested persons are urged to read the definitive proxy statement/prospectus as well as other documents to be filed with the SEC because these documents contain important information about IIAC, Zegna and the Business Combination. Shareholders of IIAC may also obtain a copy of the F-4, including the definitive proxy statement/prospectus, and other documents to be filed with the SEC without charge, by directing a request to: Investindustrial Acquisition Corp., Suite 1, 3rd Floor, 11-12 St. James’s Square, London, United Kingdom SW1Y 4LB. The definitive proxy statement/prospectus included in the registration statement can also be obtained, without charge, at the SEC’s website (www.sec.gov).

Participants in the Solicitation

IIAC and Zegna and their respective directors and executive officers may be considered participants in the solicitation of proxies with respect to the Business Combination described in this communication under the rules of the SEC. Information about the directors and executive officers of IIAC and their ownership is set forth in IIAC’s filings with the SEC, including its Form 10-K for the year ended December 31, 2020 and subsequent filings on Form 10-Q and Form 4. Additional information regarding the persons who may, under the rules of the SEC, be deemed participants in the solicitation of the IIAC shareholders in connection with the Business Combination is set forth in the Registration Statement and definitive proxy statement/prospectus filed with the SEC. These documents can be obtained free of charge from the sources indicated above.

Forward Looking Statements

This communication contains forward-looking statements within the meaning of section 27A of the Securities Act and Section 21E of the Exchange Act that are based on beliefs and assumptions and on information currently available to Zegna and IIAC. In some cases, you can identify forward-looking statements by the following words: “may,” “will,” “could,” “would,” “should,” “expect,” “intend,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “project,” “potential,” “continue,” “ongoing,” “target,” “seek” or the negative or plural of these words, or other similar expressions that are predictions or indicate future events or prospects, although not all forward-looking statements contain these words. Any statements that refer to expectations, projections or other characterizations of future events or circumstances, including strategies or plans as they relate to the Business Combination, are also forward-looking statements. These statements involve risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. Although each of Zegna and IIAC believes that it has a reasonable basis for each forward-looking statement contained in this communication, each of Zegna and IIAC caution you that these statements are based on a combination of facts and factors currently known and projections of the future, which are inherently uncertain. In addition, risks and uncertainties are described in the Registration Statement and definitive proxy statement/prospectus relating to the Business Combination filed by Zegna with the SEC and other documents filed by Zegna and IIAC from time to time with the SEC. These filings may identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Most of these factors are outside Zegna’s and IIAC’s control and are difficult to predict. Forward-looking statements in this communication include, but are not limited to, statements regarding the Business Combination, including the timing and structure of the transaction, the proceeds of the transaction and the benefits of the Business Combination. Neither Zegna nor IIAC can assure you that the forward-looking statements in this communication will prove to be accurate. These forward-looking statements are subject to a number of risks and uncertainties, including, among others, the risk that the Business Combination may not be completed in a timely manner or at all, the ability to complete the Business Combination due to the failure to obtain approval from IIAC’s shareholders or satisfy other closing conditions in the Business Combination Agreement, the occurrence of any event that could give rise to the termination of the Business Combination Agreement or the termination of any PIPE investor’s subscription agreement, the outcome of any legal proceedings that may be instituted against the parties following the announcement of the Business Combination, the ability to recognize the anticipated benefits of the Business Combination, including as a result of a delay in consummating the Business Combination, the amount of redemption requests made by IIAC’s public shareholders, costs related to the Business Combination, the risk that the Business Combination disrupts current plans and operations as a result of the announcement and consummation of

the Business Combination, general economic, political and business conditions, applicable taxes, inflation, interest rates and the regulatory environment, the risk that Zegna may not be able to maintain the recognition, integrity or reputation of its brands or is unable to anticipate trends and identify and respond to new and changing consumer preferences, Zegna’s failure to implement its strategy, any disruption in Zegna’s manufacturing and logistics facilities, fluctuations in the price or quality of, or disruptions in the availability of, raw materials used in Zegna’s products, Zegna’s inability to negotiate, maintain or renew its license agreements and strategic alliances, the outcome of any potential litigation, government or regulatory proceedings, changes in macro-economic conditions and tourist traffic and demand, Zegna’s ability to retain certain key personnel and craftsmen, any disruption in Zegna’s information technology, including as a result of cybercrimes, Zegna’s competitive position, risks related to Zegna’s management team’s limited experience in managing a public company, Zegna’s intellectual property position, including its ability to protect and maintain its intellectual property rights, fluctuations in foreign currency exchange rates that could result in currency transaction losses that negatively impact Zegna’s financial results and the anticipated transaction proceed uses and sources, the ability of the combined company to grow and manage growth profitably and retain its key employees, the inability to obtain or maintain the listing of the combined company’s securities on the New York Stock Exchange following the business combination, the impact of the global COVID-19 pandemic on any of the foregoing, and other risks and uncertainties, including those included under the heading “Risk Factors” in the Registration Statement on Form F-4 filed by Zegna with the SEC and those included under the heading “Risk Factors” in the annual report on Form 10-K for year ended December 31, 2020 of IIAC and in its subsequent quarterly reports on Form 10-Q and other filings with the SEC. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by Zegna, IIAC, their respective directors, officers or employees or any other person that Zegna and IIAC will achieve their objectives and plans in any specified time frame, or at all. The forward-looking statements in this communication represent the views of Zegna and IIAC as of the date of this communication. Subsequent events and developments may cause that view to change. However, while Zegna and IIAC may elect to update these forward-looking statements at some point in the future, there is no current intention to do so, except to the extent required by applicable law. You should, therefore, not rely on these forward-looking statements as representing the views of Zegna or IIAC as of any date subsequent to the date of this communication.

No Offer or Solicitation

This communication is not a proxy statement or solicitation of a proxy, consent or authorization with respect to any securities or in respect of the Business Combination and does not constitute an offer to sell or a solicitation of an offer to buy any securities of IIAC or Zegna, nor shall there be any sale of any such securities in any state or jurisdiction in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of such state or jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of the Securities Act of 1933, as amended.
