ADS-TEC Energy GmbH Confidentially Submits Draft Registration Statement on Form F-4 in connection with its Proposed Business Combination Agreement with European Sustainable Growth Acquisition Corp

NEW YORK, September 8, 2021 – ADS-TEC Energy GmbH (“ADS-TEC Energy” or “the Company”), a global leader in battery buffered ultrafast charging technology, and European Sustainable Growth Acquisition Corp. (NASDAQ: EUSG) (“EUSG”), a publicly traded special purpose acquisition company focused on identifying Europe-based, high growth, technology-enabled businesses that utilize green technologies, today announced the confidential submission with the Securities and Exchange Commission (“SEC”) of a draft registration statement on Form F-4 (the “Registration Statement”) relating to their previously announced definitive business combination agreement.

The draft Registration Statement was submitted to the SEC by ADS-TEC Energy plc, an affiliate of EUSG. The Registration Statement contains ADS-TEC Energy’s 2019 and 2020 financial statements following the completion of the Public Company Accounting Oversight Board Audit by the auditors of ADS-TEC Energy. While the Registration Statement is not yet effective and the information contained therein is subject to change, it contains important information about ADS-TEC Energy’s technology and business operations as well as details around the proposed business combination agreement with EUSG. Additional information about the transaction can be found on the Current Report on Form 8-K filed by EUSG with the SEC on August 11, 2021.

The business combination is expected to be completed in the fourth quarter 2021, subject to, among other things, the approval of the shareholders of EUSG, the Registration Statement being declared effective by the SEC and the satisfaction or waiver of the conditions stated in the definitive agreement. EUSG’s Class A common stock is currently traded on Nasdaq under the ticker symbol “EUSG.” Upon completion of the proposed business combination agreement, the combined company will be named ADS-TEC Energy and is expected to be listed on Nasdaq.

As previously announced, institutional investors including, amongst others, APG, Invesco, Polar Structure and SwedbankRobur, have committed to a Private Investment in Public Equity of $156 million (the “PIPE Financing”), which is anticipated to close one business day prior to the business combination. Pursuant to the business combination agreement, one of the conditions to the closing of the business combination is that the available cash in EUSG’s trust account at the closing, together with proceeds from the PIPE Financing, is not less than $150 million.
