Notification of stabilization transactions and the end of stabilization measures in accordance with Article 6 (2), (3) of the Commission Delegated Regulation (EU) 2016/1052

Luxembourg, February 14, 2022

Reference is made to the announcement dated February 2, 2022 by GP Bullhound Acquisition I SE (the "Company"), a Luxembourg incorporated newly formed special purpose acquisition company (SPAC), regarding potential stabilization activities in connection with the private placement of units (the "Units"), each consisting of one share (a "Public Share") and the right to receive ½ warrant (a "Public Warrant") at the end of the stabilization period, and the admission to trading of the Public Shares and Public Warrants on Euronext Amsterdam on February 3, 2022 (the "Listing"). The Class A Shares commenced trading on February 4, 2022. The stabilization period commenced on the same date.

Citigroup Global Markets Limited (the "Stabilization Manager"), acting as stabilization manager in connection with the Listing, informed us on February 11, 2022 that stabilization transactions have been carried out between February 4, 2022 and February 11, 2022. No further stabilization transactions have been carried out nor will be carried out after February 11, 2022 and the stabilization period has therefore ended on that date. The put right of the Stabilization Manager to sell to the Company up to such number of Public Shares that may have been acquired by the Stabilization Manager in connection with stabilization measures granted to the Stabilization Manager by the Company will not be exercised further. The Stabilization Manager has exercised its put right in relation to 390,000 Public Shares. The Company will repurchase these Public Shares and will hold them in treasury.

Further details of the stabilization activity carried out by the Stabilization Manager are set out in the table below.

Based on the above, the Company confirms final proceeds of €196,100,000 in connection with the private placement. The number of Public Shares outstanding and trading under the symbol BHND on Euronext Amsterdam will amount to 19,610,000 following the repurchase of Public Shares by the Company on February 16, 2022. The Company will hold 200,390,000 Public Shares in treasury from that date.

The Company and the Joint Bookrunners have decided to set the Separation Date (each as defined in the Prospectus (as defined below)) on February 16, 2022. After the Separation Date, the Public Shares will no longer give any right to receive ½ of a Public Warrant. On February 17, 2022, the Company will allocate whole Public Warrants to each holder that owned at least two Public Shares (or a whole multiple thereof) at the end of the Separation Date. The Public Warrants will commence trading under the symbol BHNDW on Euronext Amsterdam on February 17, 2022.

The Securities of the Company may not be offered or sold in the United States absent registration or an exemption from registration under the U.S. Securities Act of 1933, as amended (the "Securities Act"). There will be no public offering of the Securities in the United States. The Securities of the Company have not been, and will not be, registered under the Securities Act. The Securities referred to herein may not be offered or sold in Australia, Canada or Japan or to, or for the account or benefit of, any national, resident or citizen of Australia, Canada or Japan subject to certain exceptions.

This publication constitutes neither an offer to sell nor a solicitation to buy Securities. The listing of the Securities was made solely by the means of, and on the basis of, a Securities prospectus. An investment decision regarding any Securities of the Company should only be made on the basis of the Securities prospectus (the "Prospectus") that was approved by the Luxembourg Commission de Surveillance du Secteur Financier on February 3, 2022 in its capacity as competent authority under the Prospectus Regulation and Luxembourg law of 16 July 2019 on prospectuses for securities (Loi du 16 juillet 2019 relative aux prospectus pour valeurs mobilières) and passported to the Dutch Authority for the Financial Markets (the "AFM") on the same date. The Prospectus was published and made available at no cost through the website of the AFM and the Luxembourg Stock Exchange and through the website of the Company (https://www.gpbullhound.com/spac/acquisition-i-se), subject to securities law restrictions in certain jurisdictions.

The Units and the Class A Warrants are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any Retail Investor in the EEA. For these purposes, a "Retail Investor" means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU of the European Parliament and of the Council of 15 May 2014 on markets in financial instruments, as amended ("MiFID II"); (ii) a customer within the meaning of Directive (EU) 2016/97 of the European Parliament and of the Council of 20 January 2016 on insurance distribution, as amended, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II. Consequently, no key information document required by Regulation (EU) No 1286/2014 of the European Parliament and of the Council of 26 November 2014 on key information documents for packaged retail and insurance-based investment products (the "PRIIPs Regulation") for offering or selling the Units or Class A Warrants or otherwise making them available to Retail Investors in the EEA has been prepared and therefore offering or selling the Units or Class A Warrants or otherwise making them available to any Retail Investor in the EEA may be unlawful under the PRIIPs Regulation.

Solely for the purpose of the product governance requirements contained within (i) MiFID II, (ii) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 of April 7, 2016 supplementing MiFID II and (iii) local implementing measures (together, the "MiFID II Requirements"), and disclaiming any and all liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the MiFID II Requirements) may otherwise have with respect thereto, the Units, Class A Shares and Class A Warrants have been subject to a product approval process. As a result, it has been determined that (i) the Units are (a) compatible with an end target market of investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II, and (b) eligible for distribution through all distribution channels permitted by MiFID II, (ii) the Class A Shares are (a) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II, and (b) eligible for distribution through all distribution channels permitted by MiFID II and (iii) the Class A Warrants are (a) compatible with an end target market of investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II, and (b) eligible for distribution to professional clients and eligible counterparties through all distribution channels permitted by MiFID II.

Any person subsequently offering, selling or recommending the Class A Shares and Class A Warrants (a "distributor") should take into consideration the manufacturer's target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Class A Shares and Class A Warrants (by either adopting or refining the manufacturer's target market assessment) and determining appropriate distribution channels.
