Note 8 — Shareholders’ Equity

Preferred Shares

The Company is authorized to issue 1,000,000 preferred shares with a par value of $0.0001. The Company’s board of directors will be authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. The board of directors will be able to, without shareholder approval, issue preferred shares with voting and other rights that could adversely affect the voting power and other rights of the holders of the Ordinary Shares and could have anti-takeover effects.

At March 31, 2021 and 2020, there were no preferred shares issued or outstanding.

Ordinary Shares

The Company is authorized to issue 200,000,000 Class A Shares, with a par value of $0.0001 each, and 20,000,000 Class B ordinary shares, with a par value of $0.0001 each (the “Class B Shares” and, together with the Class A Shares, the “Ordinary Shares”). Holders of the Ordinary Shares are entitled to one vote for each Ordinary

Share; provided that only holders of the Class B Shares have the right to vote on the election of directors prior to the Business Combination. The Class B Shares will automatically convert into Class A Shares at the time of the Business Combination, on a one-for-one basis, subject to adjustment for share splits, share dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional Class A Shares, or equity-linked securities, are issued or deemed issued in excess of the amounts sold in the Initial Public Offering and related to the closing of the Business Combination, the ratio at which the Class B Shares shall convert into Class A Shares will be adjusted (unless the holders of a majority of the outstanding Class B ordinary shares agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of Class A Shares issuable upon conversion of all Class B Shares will equal, in the aggregate, 20% of the sum of all Ordinary Shares outstanding upon completion of the Initial Public Offering plus all Class A Shares and equity-linked securities issued or deemed issued in connection with the Business Combination, excluding any Ordinary Shares or equity-linked securities issued, or to be issued, to any seller in the Business Combination, or any Private Placement-equivalent Warrants issued to the Sponsor or its affiliates upon conversion of loans made to the Company. Holders of Founder Shares may also elect to convert their Class B Shares into an equal number of Class A Shares, subject to adjustment as provided above, at any time.

At March 31, 2021 and 2020, there were 7,540,460, and 3,437,357 Class A Shares issued and outstanding, (excluding 26,959,540 and 31,062,643 Class A shares subject to possible redemption), and there were 8,625,000 Class B Shares issued and outstanding, respectively.

Founder Shares

On February 20, 2019, an aggregate of 8,625,000 Class B Shares (the “Founder Shares”) were sold to the Sponsor at a price of approximately $0.003 per share, for an aggregate price of $25,000. This number included an aggregate of up to 1,125,000 Founder Shares that were subject to forfeiture if the over-allotment option is not exercised in full by the Underwriters in order to maintain the Initial Shareholders’ ownership at 20% of the issued and outstanding Ordinary Shares upon completion of the Initial Public Offering. The Underwriters exercised their over-allotment option in full so none of the Founder Shares were forfeited. The Founder Shares are identical to the Class A Shares included in the Units sold in the Initial Public Offering, except that the Founder Shares (i) have the voting rights described in this Note 7, (ii) are subject to certain transfer restrictions described below and (iii) are convertible into Class A Shares on a one-for-one basis, subject to adjustment pursuant to the anti-dilution provisions contained therein. The Founder Shares may not be transferred, assigned or sold until the earlier of (i) one year after the completion of the Business Combination and (ii) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction after the Business Combination that results in all of the Public Shareholders having the right to exchange their Class A Shares for cash, securities or other property.

Notwithstanding the foregoing, if the last sale price of the Class A Shares equals or exceeds $12.00 per share (as adjusted for share splits, share dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Business Combination, the Founder Shares will be released from the lock-up agreement.
