Introductory Note

As previously announced, on May 11, 2022, InterPrivate II Acquisition Corp. (“InterPrivate II”), TMPST Merger Sub I Inc., a Delaware corporation and newly formed, wholly-owned direct subsidiary of InterPrivate II (“First Merger Sub”), TMPST Merger Sub II LLC, a Delaware limited liability company and newly formed, wholly-owned direct subsidiary of InterPrivate II (“Second Merger Sub”), and Getaround, Inc. (“Getaround”) entered into an Agreement and Plan of Merger (as it may be amended and/or restated from time to time, the “Merger Agreement”). If the Merger Agreement and the transactions contemplated thereby are adopted and approved by InterPrivate II’s stockholders, and the business combination is subsequently completed, (a) First Merger Sub will merge with and into Getaround (the “First Merger”), with Getaround being the surviving corporation of the First Merger, and (b) immediately following the First Merger, Getaround will merge with and into Second Merger Sub (the “Second Merger” and, together with the First Merger, the “Mergers” and, collectively with the Mergers and other transactions described in the Merger Agreement, the “Business Combination” or “Proposed Transaction”), with Second Merger Sub being the surviving company of the Second Merger.

In connection with the Business Combination, InterPrivate II filed with the Securities and Exchange Commission (the “SEC”) a registration statement on Form S-4, as amended (File No. 333-266054) containing a proxy statement/prospectus which was declared effective on November 14, 2022 and on November 16, 2022, InterPrivate II filed a definitive proxy statement/prospectus with the SEC dated November 14, 2022 and supplements thereto dated November 23, 2022 and November 29, 2022 (as supplemented, the “Proxy Statement/Prospectus”). Capitalized terms not defined herein have their meanings defined in the Proxy Statement/Prospectus.

Item 8.01

Other Events.

As previously disclosed in the Proxy Statement/Prospectus, InterPrivate II and Getaround agreed pursuant to the Merger Agreement and the Escrow Shares Allocation Agreement, to reserve and set aside 9,333,333 shares (the “Bonus Shares”) to be allocated to the non-redeeming Public Stockholders, the designees of EarlyBirdCapital and the holders of the Class B Stock. Under that arrangement, each non-redeeming Public Stockholder was entitled to its pro rata share of the Bonus Shares based on the number of shares of Class A Stock held immediately following the Closing as a percentage of the total number of shares of Class A Stock that remain outstanding after giving effect to redemptions and the automatic conversion of the Class B Stock into shares of Class A Stock. As the holders of Class B Stock and EarlyBirdCapital’s designees are contractually obligated not to redeem, non-redeeming Public Stockholders would be entitled to fewer Bonus Shares at higher levels of redemptions by Public Stockholders at Closing, such that the maximum number of Bonus Shares available to non-redeeming Public Stockholders would be 7,420,779 Bonus Shares in the no redemption scenario, whereas in the contractual maximum redemption scenario, which assumes that 25,496,400 shares of Class A Stock are redeemed, 494,579 Bonus Shares would be allocated to non-redeeming Public Stockholders.

InterPrivate II and Getaround have agreed to restructure the Bonus Share arrangement as applied to Public Stockholders such that an aggregate of 9.0 million Bonus Shares will be allocated to non-redeeming Public Stockholders regardless of the level of redemptions at Closing. Accordingly, the aggregate number of Bonus Shares apportioned to non-redeeming Public Stockholders will be fixed at 9.0 million shares and will not vary based upon the redemption level. As revised, the number of Bonus Shares non-redeeming Public Stockholders will be entitled to receive for each outstanding share of Class A Stock held at the Closing has been increased from approximately 0.2867934 Bonus Shares to approximately 0.3478261 Bonus Shares in the no redemption scenario and from approximately 1.3063387 Bonus Shares to approximately 18.1013677 Bonus Shares in the contractual maximum redemption scenario, which assumes that 25,496,400 shares of Class A Stock are redeemed, which per share amount would significantly decrease after giving effect to the maximum exercise of any non-redemption agreements.

In addition, the number of Bonus Shares apportioned to the Initial Stockholders, comprised of the Sponsor, EarlyBirdCapital’s designees and the current and former independent directors of InterPrivate II, will continue to be capped at the amount described in the Proxy Statement/Prospectus, which is the number of Bonus Shares they would have received in a no redemption scenario. The mechanism for allocating the Bonus Shares or other shares of Class A Stock of InterPrivate II to the Initial Stockholders is expected to be through an amendment to the number of Escrow Shares and/or through one or more agreements under which the Sponsor would forfeit all or a portion of the Bonus Shares to which it would otherwise be entitled to receive in exchange for an entitlement to an equivalent number of shares of InterPrivate II or securities of Getaround that would convert automatically into shares of Class A Stock of InterPrivate II at Closing. In no event will the manner of participation by the Initial Stockholders in the Bonus Shares reduce the 9.0 million Bonus Shares allocated to non-redeeming Public Stockholders or change the aggregate number of shares issuable by InterPrivate II in connection with the Business Combination.

Supplemental Disclosures to the Proxy Statement/Prospectus

The following disclosures in this Current Report on Form 8-K supplement the disclosures contained in the Proxy Statement/Prospectus and should be read in conjunction with the disclosures contained in the Proxy Statement/Prospectus, which in turn should be read in its entirety. All page references are to the Proxy Statement/Prospectus and terms used below, unless otherwise defined, shall have the meanings ascribed to such terms in the Proxy Statement/Prospectus.

The disclosure on page 27 under the heading “Q. Do I have redemption rights?” is hereby amended as follows:

The second full paragraph and the table that follows are amended and supplemented as follows:

In addition, if a Public Stockholder does not redeem their shares of Class A Stock, but other Public Stockholders do elect to redeem, the non-redeeming Public Stockholder would own shares with a lower book value per share. The aggregate number of Bonus Shares available to non-redeeming Public Stockholders does not change as the number of shares of Class A Stock redeemed increases. The Initial Stockholders will be entitled to receive a fixed amount of 1,912,549 Bonus Shares (or a combination of Bonus Shares and other entitlements to shares of Class A Stock, but in no event more than 1,912,549 shares). The non-redeeming Public Stockholders will be entitled to receive their pro rata share of 9.0 million Bonus Shares regardless of the level of redemptions at Closing. However, as the number of shares of Class A Stock redeemed increases, the number of additional Bonus Shares entitled to be received in respect of each Public Share also increases from approximately 0.3478261 Bonus Shares (assuming the no redemption scenario), to approximately 18.1013677 Bonus Shares (assuming that 25,496,400 shares of Class A Stock are redeemed for purposes of the contractual maximum redemption scenario), which per share amount would significantly decrease after giving effect to the maximum exercise of any non-redemption agreements. For informational purposes only, the table below provides an illustration of such increase. On a pro forma basis and for the nine- month period ended September 30, 2022, the basic and diluted net loss per share attributable to holders of Class A Stock ranges from $(1.46) per share assuming the no redemption scenario and $(1.85) per share assuming the contractual maximum redemption scenario.

(1)	Based on $260,207,445 held in the Trust Account as of September 30, 2022.

(2)	Reflects the contractual maximum redemption scenario, representing redemptions of 25,496,400 shares of Class A Stock, the maximum amount of redemptions that would still enable InterPrivate II to have sufficient cash to satisfy the minimum cash closing condition in the Merger Agreement.

For illustrative purposes only, assuming a price of $10.00 per share of Class A Stock at the Closing of the Business Combination, non-redeeming Public Stockholders, after receiving Bonus Shares, will own Class A Stock with an assumed value ranging between $13.48 (assuming the no redemption scenario) and $247.72 (assuming the

contractual maximum redemption scenario) for each outstanding share of Class A Stock. Based on the closing price of $10.04 per share of Class A Stock on the NYSE on November 29, 2022, non-redeeming Public Stockholders, after receiving Bonus Shares, will own Class A Stock with an assumed value ranging between $13.53 (assuming the no redemption scenario) and $248.71 (assuming the contractual maximum redemption scenario) for each outstanding share of Class A Stock.
