Item 4.

Purpose of the Transaction

Item 4 of the Original Schedule 13D is amended as follows:

Concurrently with the closing of the transactions contemplated by the Business Combination Agreement, (i) the Sponsor and certain other stockholders of the Issuer entered into a Registration Rights Agreement with the Issuer (the “Registration Rights Agreement”) pursuant to which (among other things) the Issuer granted the stockholders party thereto certain rights to have their securities of the Issuer registered under the Securities Act of 1933, as amended, (ii) the Issuer consummated the transactions contemplated by separate subscription agreements (each a “Subscription Agreement”) with a number of investors (including Kensington), pursuant to which (among other things) such investors agreed to purchase, and Kensington agreed to issue to such investors, PIPE Units (as defined below) at a price of $10.00 per PIPE Unit, and Kensington purchased 111,000 PIPE Units, (iii) in connection with the Sponsor Liquidation, the Sponsor distributed securities owned by it to its members, including 2,497,142 shares of Common Stock and 4,700,000 Warrants (as defined below) to Kensington Capital Partners, LLC, and 1,000,000 shares of Common Stock to Justin Mirro, as trustee of the Justin E. Mirro 2020 Qualified Annuity Trust dated 6/27/20, and (iv) the Issuer issued 200,000 Working Capital Warrants (as defined below) to Justin Mirro. The Subscription Agreements provide the investors thereunder certain registration rights with respect to the securities they purchased therein.

As used herein “PIPE Unit” means (i) one share of Common Stock, and (ii) one warrant (each, a “PIPE Warrant”) to purchase one share of Common Stock. The terms of the PIPE Warrants are governed by a warrant agreement (the “PIPE Warrant Agreement”) entered by the Issuer and Continental Stock Transfer & Trust Company, as warrant agent (“CST”). The PIPE Warrants are substantially identical to the Issuer’s existing public warrants, except that the exercise price of each PIPE Warrant is $12.50 per share (instead of $11.50 per share, which is the exercise price for the existing public warrants) and the average sales price of the Common Stock will need to exceed $20.00 per share (instead of $18.00 per share for the existing public warrants) for the Issuer to be able to redeem the PIPE Warrants; also, the PIPE Warrants will not be listed on any securities exchange.

As used herein “Warrants” has the meaning assigned to such term in the Warrant Agreement, dated as of March 1, 2022 (the “Initial Warrant Agreement”) between the Issuer and CST.

As used herein “Working Capital Warrants” has the meaning assigned to such term in the Initial Warrant Agreement.

The description of the Initial Warrant Agreement is qualified in its entirety by reference to the full text of such agreement, a copy of which was filed by the Issuer as Exhibit 4.1 to the Form 8-K filed by the Issuer with the SEC on March 4, 2022 (and is incorporated by reference herein as Exhibit 4.2).
