NEW YORK and LONDON, March 1, 2021 - [BUSINESS WIRE] - CIIG Merger Corp. (NASDAQ: CIIC) (“CIIG”) today announced that the U.S. Securities and Exchange Commission (“SEC”) has declared effective the registration statement on Form F-4 of Arrival Group (File No. 333-251339) (as amended, the “Registration Statement”), which includes a definitive proxy statement/prospectus in connection with CIIG’s special meeting of stockholders (the “Special Meeting”) to consider the previously announced proposed business combination (the “Business Combination”) with Arrival S.à r.l. (“Arrival”). Additionally, CIIG today announced that it has set a record date of February 16, 2021 (the “Record Date”) and a meeting date of March 19, 2021 for its Special Meeting.

Peter Cuneo, Chairman & Chief Executive Officer of CIIG said, “We are entering the final stages of the transaction process, which will result in Arrival Group becoming a public company upon approval of the transaction by CIIG stockholders and the satisfaction of the other conditions to the transaction. This transaction is expected to enable Arrival to continue scaling up its bold new approach to EV design and production, including the deployment this year of its first US Microfactory in South Carolina and a new U.S. Headquarters in North Carolina.”

“Since announcing the transaction, we have seen the seismic shift towards electrification accelerate rapidly in line with global public policy, and we believe Arrival remains well-placed to capitalize on this enormous opportunity through EV products that are price competitive to diesel equivalents. In that time, Arrival has continued to move towards bringing its best-in-class products to market – starting with the commercial Bus and Van models, which will begin production at the end of this year and beginning of 2022 respectively,” added Michael Minnick, Chief Investment Officer of CIIG.

Gavin Cuneo, Chief Operating Officer of CIIG continued, “Arrival is challenging the 100-year-old automotive production process, by developing vertically integrated in-house technologies and combining them with its pioneering and rapidly scalable Microfactory assembly process. We believe this decentralized approach brings production to local communities and dramatically reduces the cost of EVs to accelerate mass adoption globally. We are thrilled about the company’s potential to transform this industry once the planned transaction is closed this month.”

CIIG’s stockholders of record at the close of business on the Record Date are entitled to receive notice of the Special Meeting and to vote the shares of common stock of CIIG owned by them at the Special Meeting. In light of the COVID-19 pandemic and to support the well-being of CIIG’s stockholders and partners, the Special Meeting will be conducted virtually. In connection with the Special Meeting, CIIG’s stockholders that wish to exercise their redemption rights must do so no later than 4:30 p.m. ET on March 17, 2021 by following the procedures specified in the definitive proxy statement/prospectus for the Special Meeting. There is no requirement that stockholders affirmatively vote for or against the Business Combination at the Special Meeting in order to redeem their shares for cash.

As announced previously, the Business Combination is to be effected through a newly created holding company, Arrival Group, and CIIG and Arrival will become wholly-owned subsidiaries of Arrival Group upon the consummation of the Business Transaction. Peter Cuneo, CIIG’s Chairman and CEO, will serve as the Non-Executive Chairman of the Arrival Group Board of Directors upon the closing. CIIG’s Class A common stock is currently traded on NASDAQ under the symbol “CIIC.” In connection with the closing of the transaction, Arrival Group ordinary shares and warrants will be Nasdaq-listed under the new ticker symbols “ARVL” and “ARVLW,” respectively.

The Record Date determines the holders of CIIG’s common stock entitled to receive notice of and to vote at the Special Meeting, and at any adjournment or postponement thereof, whereby stockholders will be asked to approve and adopt the Business Combination, and such other proposals as disclosed in the definitive proxy statement included in the Registration Statement. If the Business Combination is approved by CIIG stockholders, CIIG anticipates closing the Business Combination shortly after the Special Meeting, subject to the satisfaction or waiver (as applicable) of all other closing conditions.

The Special Meeting will take place at 10:00 a.m., Eastern Time, on March 19, 2021 via a virtual meeting at the following address: www.virtualshareholdermeeting.com/CIIC2021SM. CIIG stockholders entitled to vote at the Special Meeting will need the 16-digit meeting control number that is printed on their respective proxy cards to enter the Special Meeting. CIIG recommends that stockholders wishing to vote at the Special Meeting log in at least 15 minutes before the Special Meeting starts. Please note that CIIG stockholders will not be able to attend the Special Meeting in person. CIIG encourages its stockholders entitled to vote at the Special Meeting to vote their shares via proxy in advance of the Special Meeting by following the instructions on the proxy card.

A list of CIIG stockholders entitled to vote at the Special Meeting will be open to the examination of any CIIG stockholder, for any purpose germane to the Special Meeting, during regular business hours for a period of ten calendar days before the Special Meeting.
