Press Release

Energy Transition Partners successfully raises €175 million via a private placement of Units

First day of trading on Euronext Amsterdam will be Monday 19 July 2021

Amsterdam – 16 July 2021

Energy Transition Partners B.V. ("Energy Transition Partners" or the "Company"), a special purpose acquisition company ("SPAC") sponsored by Energy Transition Sponsor LLP (the "Sponsor") and cofounded by Tony Hayward, Alex Beard and Tom Daniel (together, the "Founders"), today announces that it has successfully raised €175 million in a private placement.

The Company intends to capitalize on the proven domain expertise, significant experience in public market leadership, extensive deal sourcing capabilities, and decades of experience in executing investments and transactions of its Founders, and on the support provided by its highly experienced and complementary board of directors, as it targets a partnership (a "Business Combination") with a business or company operating in the energy transition sector that is headquartered or operating in the European Economic Area, Switzerland or the United Kingdom.

Co-Founder of the Company, Alex Beard, has subscribed for 1,000,000 Units in the Offering for an aggregate subscription price of €10,000,000, demonstrating strong alignment of interest with all investors. The Sponsor has subscribed for Founder Shares and will subscribe for Founder Warrants, resulting in gross proceeds in the amount of €9.79 million to be used to cover the costs related to: (i) the Offering (as defined below) and Admission (as defined below), (ii) negative interest rates (up to 50bps per annum over the course of two years), (iii) the initial underwriting commission payable to the Sole Global Coordinator (as defined below) in connection with the Offering, (iv) the search for, and completion of, a Business Combination and (v) other running costs of the Company.

Energy Transition Partners has assembled a high-quality investor base, including many of the most notable and experienced public market investors in Europe.

The Company will have 24 months from the Settlement Date (as defined below) to complete a business combination, subject to a six-month extension period if approved by the general meeting of the Company.

J.P. Morgan AG is acting as sole global coordinator and sole bookrunner for the Offering (the "Sole Global Coordinator").

DETAILS OF THE OFFERING

The Company has completed the private placement (the "Offering") of 17,500,000 units (the "Units"), each consisting of one ordinary share (an "Ordinary Share") and one-third (1/3) of a warrant (a "Warrant"), at a price of €10.00 per Unit raising gross proceeds of €175 million. The Offering was launched on 15 July 2021.

The Company has applied for admission (the "Admission") of all of the Ordinary Shares and, separately, the Warrants to listing and trading on Euronext Amsterdam, the regulated market operated by Euronext Amsterdam N.V. ("Euronext Amsterdam"), under the symbols "ENTPA" and "ENTPW", respectively. Trading on an "as-if-and-when-issued/delivered" basis on Euronext Amsterdam in the Units is expected to commence at 09:00 CEST on 19 July 2021 (the "First Trading Date"). Payment (in euro) for, and delivery of, the Units is expected to take place on 21 July 2021 (the "Settlement Date'").

Although the Ordinary Shares and the Warrants are offered in the form of Units in the context of the Offering, the underlying Ordinary Shares and Warrants will trade separately from the First Trading Date on two listing lines on Euronext Amsterdam. The Units themselves will not be listed or admitted to trading on Euronext Amsterdam or any other trading platform.

Investing in the Company involves certain risks. A description of these risks, which include risks relating to the Company as well as risks relating to the Offering, the Ordinary Shares and the Warrants, is included in the Prospectus. This announcement also serves as the pricing statement related to the Offering as required by article 17(2) of Regulation (EU) 2017/112 (the Prospectus Regulation).

In relation to each member state of the European Economic Area (each, a "Member State"), no Units, Ordinary Shares or Warrants have been offered or will be offered , except to any legal entity which is a qualified investor as defined in Article 2 of the Prospectus Regulation, provided that no such offer of Units, Ordinary Shares or Warrants shall require the Company to publish a prospectus pursuant to Article 3 of the Prospectus Regulation or supplement a prospectus pursuant to Article 23 of the Prospectus Regulation.

The Units and the 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.

Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended the 'PRIIPs Regulation') for offering or selling the Units or the Warrants or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Units or the Warrants or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

For these purposes, a "retail investor" means a person who is one (or more) of: (i) a retail client, as defined in Directive (EU) 2014/65/EU on markets in financial instruments (as amended) and implemented in the United Kingdom as it forms part of the domestic law of the United Kingdom by virtue of the EUWA ("UK MIFID II"); (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended) as it forms part of the domestic law of the United Kingdom by virtue of the EUWA, where that customer would not qualify as a professional client as defined in UK MIFID II; or (iii) not a qualified investor as defined in Article 2 of the UK Prospectus Regulation. Consequently, no key information document required by the Regulation (EU) No 1286/2014 as it forms part of the domestic law of the United Kingdom by virtue of the EUWA (the "UK PRIIPs Regulation") for offering or selling the Units and the Warrants or otherwise making them available to retail investors in the United Kingdom has been prepared and, therefore, offering or selling the Units and the Warrants or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.
