See Item 4 of this Schedule 13D, which information is incorporated herein by reference.

In December 2020, the Sponsor purchased 8,625,000 shares of the Issuer’s Class B common stock (“Class B Common Stock”, such 8,625,000 shares the “Founder Shares”) for an aggregate price of $25,000. Of these Founder Shares, 200,000 were subsequently transferred to the independent directors of the Issuer for their service on the Issuer’s board of directors.

On March 8, 2021, the Issuer consummated its Initial Public Offering (the “IPO”) of 34,500,000 units, each consisting of one share of common stock and one-third of one warrant to purchase one share of common stock for $11.50 per share, which amount includes 4,500,000 units that were subject to the underwriters’ over-allotment option, which was exercised in full.

In a private placement (the “Private Placement”) that occurred simultaneously with the consummation of the IPO, the Sponsor purchased an aggregate of 6,066,667 warrants (“Private Placement Warrants”) at $1.50 per Private Placement Warrant, generating total proceeds of $9,100,000. A portion of the proceeds from the sale of the Private Placement Warrants were added to the net proceeds from the IPO deposited in the Issuer’s SPAC trust account (the “Trust Account”). If the Issuer does not complete a business combination within the period (the “Combination Period”) allowed by Issuer’s amended and restated certificate of incorporation (as amended on March 2^nd, 2023, the “Current Charter”), the Private Placement Warrants will expire worthless. The Private Placement Warrants are non-redeemable for cash and exercisable on a cashless basis so long as they are held by the initial purchasers or their permitted transferees.

Pursuant to Letter Agreements (as defined below) described in Item 6 of this Schedule 13D, which information is incorporated herein by reference, each of the Sponsor and Mr. Ahmad, among others, agreed: (1) to waive their redemption rights with respect to their Founder Shares and public shares, insofar as rights would enable them to receive funds from the Trust Account, in connection with the completion of the Issuer’s initial business combination or any amendment to the provisions of the Issuer’s amended and restated certificate of incorporation relating to the Issuer’s pre-initial business combination activity and related stockholders’ rights; and (2) to waive their rights to liquidating distributions from the Trust Account with respect to any Founder Shares they hold, if the Issuer fails to complete its initial business combination within the Combination Period from closing of the IPO (although they will be entitled to liquidating distributions from the Trust Account with respect to any shares of Class A Common Stock included as part of the units sold in the IPO they hold if the Issuer fails to complete its initial business combination within the prescribed time frame). Under the Current Charter, the shares of Class B Common Stock can be converted into Class A Common Stock at any time at the option of the holder, on a one-for-one basis, subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like.

In the interest of extending the Combination Period, which was set to expire on March 8, 2023, and maintaining flexibility to retain stockholders and meet NASDAQ continued listing requirements following any stockholder redemptions in connection with a vote to extend the Combination Period, the Issuer amended its charter to extend the Combination Period and allow its holders of Founder Shares, including the Sponsor, to convert their Class B Common Stock shares into Class A Common Stock. On March 2, 2023, the Sponsor elected to convert 8,424,999 of its 8,425,000 shares of Class B Common Stock into 8,424,999 shares of Class A Common Stock pursuant to the terms of the Current Charter. Through this conversion, the Sponsor agreed that it would (i) not vote any shares of Class A Common Stock that it receives by converting Class B Common Stock into Class A Common Stock until after the closing of a business combination and (ii) not have redemption rights or otherwise be entitled to any distribution from the Trust Account by virtue of the Sponsor’s ownership of Class A Common Stock that it receives by converting Class B Common Stock into Class A Common Stock. The election to convert is qualified in its entirety by reference to the full text of such conversion agreement (the “Share Conversion Election Notice”), a copy of the notice of which is filed as Exhibit III hereto.

The source of funds for the acquisitions described above was the working capital of the Sponsor. The securities owned by the Reporting Persons have been acquired for investment purposes. The Reporting Persons may acquire additional securities of the Issuer, and, subject to the agreements described below in Item 6, retain or sell all or a portion of the securities then held in the open market or in privately negotiated transactions. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Any actions the Reporting Persons might undertake with respect to securities of the issuer may be made at any time and from time to time without prior notice and will be dependent upon the Reporting Persons’ review of numerous factors, including, but not limited to: an ongoing evaluation of the Issuer’s business, financial condition, operations and prospects; price levels of the Issuer’s securities; general market, industry and economic conditions; the relative attractiveness of alternative business and investment opportunities; and other future developments.

As Chairman of the Board of Directors and Chief Executive Officer of the Issuer, Mr. Ahmad may be involved in making material business decisions regarding the Issuer’s policies and practices and may be involved in the consideration of various proposals considered by the Issuer’s board of directors.

Other than as described above and in Item 6 of this Schedule 13D, the Reporting Persons do not currently have any plans or proposals that relate to, or would result in, any of the matters listed in Item 4, although, depending on the factors discussed herein, the Reporting Persons may change their purpose or formulate different plans or proposals with respect thereto at any time.

(a), (b) The responses of the Reporting Persons with respect to Rows 7 through 13 of the respective cover pages of the individual Reporting Persons to this Schedule 13D are incorporated herein by reference.

The Reporting Persons’ aggregate percentage of beneficial ownership is approximately 69.3% of the outstanding shares of the Class A Common Stock. Calculations of the percentage of the shares of Class A Common Stock beneficially owned assume 12,157,610 shares of Class A Common Stock outstanding, based on information included in the Issuer’s Current Report on Form 8-K filed on March 3, 2023.

The Sponsor may be deemed to have beneficial ownership of 8,424,999 shares of Class A Common Stock. Mr. Ahmad may be deemed to have beneficial ownership of 8,424,999 shares of Class A Common Stock.
