Ermenegildo Zegna Group OUR VISION ...AND LET ME TELL YOU WHY WE WERE ALL WEARING A SUIT, AND TODAY I'M NOT... SECTION 1 CONFIDENTIAL 4#6Ermenegildo Zegna Group My name is Ermenegildo «Gildo>> Zegna. What am I doing in New York? My grandfather, Ermenegildo Zegna, was born near the turn of the century in Trivero, a poor and remote village in the foothills of the Italian Alps. At that time, the most sought-after wool fabrics were made in England. My grandfather's dream was to produce in Trivero the world's best fabrics. This took years of hard work. He then traveled back and forth across the Continent persuading. Europe's finest tailors that what he was selling had no equal on earth. His reputation grew, and so did his factory. Profits were used to build homes, hospitals and recreational facilities the employees. My grandfather loved and appreciated nature. In the moun- tains he planted one million trees. He also built a road from: the bottom of the valley to the top of the Bielmonte mountain. The "Panoramica Zegna", another vision which became a reali- ty, is forever a symbol of his dedication and commitment to beauty. Grandfather also established the highly prized Ermenegildo Zegna trophy, awarded annually to the grower of the finest Australian merino sheep wool. Soon fifty percent of the very best wool produced in the world was purchased by his company. The King of Italy was very impressed by Grandfather's achievements. In recognition, he honored him with the title, "Count of Monterubello". When his sons, Aldo and Angelo, took over grandfather's responsibilities, they followed in his footsteps and carried the dream even further. Their goal was to design and produce gentlemen's clothing with exquisite Italian flair. Starting with the world's best natural fibers, and using a complete and uni- que manufacturing process, they created a totally coordinated line of products As new factories were built for the production of coordinated lines of clothing, sportswear and accessories, the Ermenegildo Zegna Group came into existence, soon becoming a world leader. The management team to which I belong has trained in Italy and abroad. We have all learned that only through dedication, creativi- ty, and innovation can we excel in our field. Ermenegildo Zegna You will find that in one respect nothing has changed since my grandfather's time; we have re- tained his vision for legendary quality in everything we do. Ermenegildo Zegna Corp. 1984, Inc I too have a dream-the success of our company in America. That's why I've come to the United States. Че 5#7Zegna FW 2021 collection.

In the wholesale channel, Zegna is subject to certain risks arising from points of sale operated by third parties, and it is dependent on its joint venture partners and franchisees to sell its products in certain markets. Fluctuations in the price or quality of, or disruptions in the availability of, raw materials used in Zegna's products could cause it to incur increased costs, disrupt its manufacturing processes or prevent or delay Zegna from meeting customers' demands. Zegna could be adversely affected if it is unable to negotiate, maintain or renew its license agreements and strategic alliances. Zegna's business is dependent on tourist traffic and demand. Zegna's business success is dependent on certain key personnel. Zegna is dependent on highly specialized craftsmanship and craftsmanship skills. Zegna is dependent on the protection of its intellectual property rights. A disruption in Zegna's information technology, including as a result of cybercrimes, could compromise confidential and sensitive information. Zegna is subject to certain risks related to related party transactions. Zegna is exposed to currency related risks and credit risk. The markets in which Zegna operates are highly competitive. Global economic conditions and macro events may adversely affect Zegna. Zegna is subject to legal and regulatory risk. Changes in tax, tariff or fiscal policies could adversely affect demand for Zegna's products. Changes to taxation or the interpretation or application of tax laws could have an adverse impact on Zegna's results of operations and financial condition. Zegna currently benefits or seeks to benefit from certain special tax regimes, which may not be available in the future. Zegna's management team has limited experience managing a public company. IIAC's founders, directors, officers, advisors and their affiliates may elect to purchase IIAC Class A ordinary shares or IIAC warrants from public shareholders, which may influence the vote on the business combination and reduce the public "float" of IIAC's Class A ordinary shares. The ability of IIAC's shareholders to exercise redemption rights with respect to a large number of outstanding IIAC Class A ordinary shares could increase the probability that the business combination would not occur. The parties may be unable to successfully or timely consummate the business combination. Prior to the closing of the business combination, uncertainties about the transaction may cause a loss of key management personnel and other key employees. Prior to the closing of the business combination, uncertainties about the transaction may cause third parties to delay or defer decisions concerning Zegna or seek to change existing arrangements. The parties expect to incur significant transaction costs in connection with the business combination. Fluctuations in foreign currency exchange rates could result in currency transaction losses that negatively impact Zegna's financial result and the anticipated transaction uses and sources.

Use of Data To the extent available, the industry, market and competitive position data in the Presentation has come from official or third-party sources. Third party industry publications, studies and surveys generally state that the data contained therein have been obtained from sources believed to be reliable, but that there is no guarantee of the accuracy or completeness of such data. Further, no representation is made as to the reasonableness of the assumptions made by the third-party sources. While the Company reasonably believes that each of these publications, studies and surveys has been prepared by a reputable source, the Company has not independently verified the data contained therein. In addition, certain of the industry, market and competitive position data contained in the Presentation has come from the Company's own internal research and estimates based on the knowledge and experience of the Company's management in the markets in which the Company operates. Such research and estimates, and their underlying methodology and assumptions, have not been verified by any independent source for accuracy or completeness and are subject to change. The Presentation is provided as of its date, is for informational purposes only, is subject to material change and is not intended to be all-inclusive or to contain all the information that a person may desire in considering an investment in connection with a Transaction, and neither the Company nor the SPAC intend, and do not assume any obligation or duty, to update the Presentation at a later date.

Certain amounts that appear in this presentation may not sum due to rounding. Use of Projections This presentation contains financial projections and certain "forward-looking statements" regarding the Company's business strategies, market potential, future financial performance and other matters. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements and any such projections, growth targets, statements and information reflect various estimates and assumptions concerning anticipated results. Forward-looking statements include statements regarding our future financial position and performance, business strategy, budgets, projected costs, plans, synergies and objectives of management for future operations. Without limiting the foregoing, the words "believes," "anticipates," "plans," "expects," "intends," "pro forma," "estimated," "forecasted," "projection" and similar expressions used in connection with any discussion of future operating or financial performance identify forward-looking statements, but the absence of these words does not necessarily mean that a statement is not forward-looking. No representations or warranties are made by the Company, the SPAC or any of their respective affiliates or representatives as to the accuracy of any such projections, statements and information. It is understood and agreed that any such projections, targets, statements and information are made as of their respective date, are not to be viewed as facts and are subject to significant business, financial, economic, operating, competitive and other risks, uncertainties and contingencies many of which are beyond the Company's control, that no assurance can be given that any particular financial projections ranges, or targets will be realized, that actual results may differ from projected results and that such differences may be material. These factors, risks and uncertainties include, but are not limited to, the risk factors listed elsewhere in this appendix. Other unknown or unpredictable factors or factors currently considered immaterial also could have an adverse effect on our results. Consequently, there can be no assurance that the actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, us. These forward-looking statements are based on management's expectations and beliefs about future events based on information available to them as of the date each such forward-looking statements is made. As with any projection or forecast, they are inherently susceptible to uncertainty and changes in circumstances. Except as required by law, the Company and the SPAC, and their respective affiliates and representatives are under no obligation to, and expressly disclaim any obligation to, update or alter any forward-looking statements whether as a result of any such changes, new information, subsequent events or otherwise. Ermenegildo Zegna Group CONFIDENTIAL 62#64DISCLAIMER (2/2) Non IFRS Financial Measures The document includes certain non-IFRS financial measures (including on a forward-looking basis), such as Adjusted EBIT, Adjusted EBITDA, Net Financial Indebtedness, Operating Capex and Adjusted Operating Cash Flow. These non-IFRS measures are an addition, and not a substitute for or superior to, measures of financial performance prepared in accordance with IFRS and should not be considered as an alternative to net income, operating income or any other performance measures derived in accordance with IFRS. The SPAC and Company believe that these non-IFRS measures of financial results (including on a forward forward-looking basis) provide useful supplemental information to investors about the Company. The Company's management uses forward-looking non-IFRS measures to evaluate the Company's projected financials and operating performance. However, there are a number of limitations related to the use of these non-IFRS measures and their nearest IFRS equivalents, including that they exclude significant expenses that are required by IFRS to be recorded in the Company's financial statements. In addition, other companies may calculate non-IFRS measures differently, or may use other measures to calculate their financial performance, and therefore, the Company's non-IFRS measures may not be directly comparable to similarly titled measures of other companies. Additionally, to the extent that forward-looking non-IFRS financial measures are provided, they are presented on a non-IFRS basis without reconciliations of such forward forward-looking non-IFRS measures due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations. Unaudited Core Financial Information This presentation contains certain unaudited historical and prospective financial measures referred to as "core" measures ("the Unaudited Core Financial Information"), which exclude certain businesses of the Company that are expected to be divested (by way of one or more demergers or other transfers) prior to the consummation of the Transaction (such divestitures, collectively, the "Divestment"). The Divestment concerns (i) the Company's real estate business (consisting of the Company's subsidiary E.Z. Real Estate S.r.l., which directly or indirectly holds substantially all of the Company's real estate assets, as well as certain properties owned by Lanificio Ermenegildo Zegna e Figli S.p.A. ("Lanificio"), including part of Lanificio's industrial building located in Valdilana and Lanificio's hydroelectric plants), (ii) its 10% equity interest in Elah Dufour S.p.A. and certain related contractual rights and obligations, and (iii) its equity stake in Agnona S.r.l. (70% of which was divested in January 2021, and the remaining 30% of which is expected to be divested prior to the consummation of the Transaction). The prospective Unaudited Core Financial Information included in this presentation excludes, in addition to the Divestment described above, the impact of the following transactions occurred after December 31, 2020 (unless otherwise indicated): (a) the purchase of a 60% equity interest in Tessitura Ubertino S.r.l., which was consummated on June 4, 2021; and (b) the purchase of a 40% equity interest in Filati Biagioli Modesto S.p.A. (which following consummation will be consolidated line by line in the Zegna consolidated financial statements), was consummated on July 14, 2021 The word "core" associated with any non-IFRS measures has no other meaning but the one described above. The Unaudited Core Financial Information has been prepared solely for the purpose of illustrating the effects on a hypothetical basis of the Divestment on the Company's consolidated income statement and consolidated statement of financial position, as if the Divestment had occurred on December 31, 2017. The Unaudited Core Financial Information does not constitute, nor should it in any way be construed as, pro forma financial information within the meaning set forth under Regulation S-X under the Securities Act. In light of the foregoing, in reviewing the Unaudited Core Financial Information it is necessary to consider that the actual impact of the Divestment on the Company's consolidated results of operations and financial position in future periods may differ, also significantly, from the impact presented in the Unaudited Core Financial Information. Restated Financial Information This Presentation contains financial information for the Company as of December 31, 2020 and 2019 and for each of the three years ended December 31, 2020, prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB"). Such financial information has been restated as discussed in Note 43 to the Zegna audited consolidated financial statements as of December 31, 2020 and 2019 and for each of the three years ended December 31, 2020 included in the Registration Statement on Form F-4 which was filed by Zegna with the SEC on August 28, 2021.
