Item 4. Purpose of Transaction.

Founder Shares

In connection with the organization of the Issuer, the Sponsor purchased 11,500,000 shares of Series F Common Stock (the “Founder Shares”) for an aggregate amount of $25,000, pursuant to a Securities Subscription

Agreement, dated January 27, 2021, between the Sponsor and the Issuer (as amended, the “Securities Subscription Agreement”), and on April 8, 2021, the Sponsor surrendered 2,875,000 Founder Shares to the Issuer for no consideration resulting in an aggregate of 8,625,000 shares of Series F Common Stock outstanding, as more fully described in Item 6 of this Schedule 13D, which information is incorporated herein by reference. As described in the Issuer’s registration statement on Form S-1 (File No. 333-252910) under the heading “Description of Securities—Founder Shares,” the shares of Series F Common Stock will automatically convert into shares of Series B Common Stock at the time of the Issuer’s partnering transaction, or earlier 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, and certain anti-dilution rights and have no expiration date. Prior to and following the consummation of the partnering transaction, at the option of the holder, shares of Series B Common Stock are convertible into shares of Series A Common Stock.

Units

On May 25, 2021, in connection with the Issuer’s IPO, the Sponsor acquired 4,000,000 units (the “Units”) of the Issuer at $10.00 per Unit. Each Unit consists of one share of Series A Common Stock and one-third of one warrant, each whole warrant entitling the holder to purchase one share of Series A Common Stock at $11.50 per share (as described more fully in the Issuer’s Final Prospectus, dated May 25, 2021). The warrants included in the Units will become exercisable on the later of 30 days after the completion of the Issuer’s partnering transaction or 12 months from the closing of the Issuer’s IPO. The warrants included in the Units will expire five years after the completion of the Issuer’s partnering transaction or earlier upon redemption or liquidation.

Private Placement Units

On May 25, 2021, in connection with the Issuer’s IPO, pursuant to the Private Placement Units Purchase Agreement, dated May 25, 2021, by and between the Issuer and the Sponsor (the “Private Placement Units Purchase Agreement”), the Sponsor acquired 1,000,000 units at a purchase price of $10.00 per unit (the “Private Placement Units”). On June 1, 2021, in connection with the underwriters’ full exercise of their over-allotment option, the Sponsor acquired an additional 90,000 Private Placement Units, and holds, collectively, an aggregate number of 1,090,000 Private Placement Units. Each Private Placement Unit will consist of one share of Series A Common Stock and one-third of one warrant (the “Private Placement Warrants”).

Each whole Private Placement Warrant is exercisable for one share of Series A Common Stock at a price of $11.50 per share. The Private Placement Warrants are identical to the warrants included in the Units sold in the Issuer’s IPO, except that such Private Placement Warrants (i) may be exercised for cash or on a cashless basis, (ii) are not subject to being called for redemption (except in certain circumstances when the warrants included in the Units are called for redemption and a certain price per share of Series A Common Stock threshold is met) and (iii) subject to certain limited exceptions, will be subject to transfer restrictions until 30 days following the consummation of the Issuer’s partnering transaction. If the Private Placement Warrants are held by holders other than the Sponsor or its permitted transferees, the Private Placement Warrants will be redeemable by the Issuer in all redemption scenarios and exercisable by holders on the same basis as the warrants. The summary of such Private Placement Units Purchase Agreement contained herein is qualified in its entirety by reference to the full text of such agreement, a copy of which is filed as an exhibit hereto.

On May 28, 2021, in connection with the Issuer’s IPO, the Issuer, the Sponsor and Post Holdings entered into an investor rights agreement (the “Investor Rights Agreement”), pursuant to which the Sponsor is entitled to request that the Issuer register certain of its securities held by the Sponsor for sale under the Securities Act and to have the securities covered thereby registered for resale pursuant to Rule 415 under the Securities Act of 1933 (the “Securities Act”). In addition, the Sponsor has the right to include its securities in other registration statements filed by the Issuer.

The description of the Investor Rights Agreement is qualified in its entirety by reference to the full text of such agreement, a copy of which is filed as an exhibit hereto.

Insider Letter

On May 25, 2021, the Issuer entered into a letter agreement (the “Letter Agreement”) with the Sponsor and each of the Issuer’s directors and executive officers. Pursuant to the Letter Agreement, the Sponsor has agreed that if the Issuer seeks stockholder approval of a proposed partnering transaction it will vote all shares held by it in favor of such proposed partnering transaction.

Pursuant to the Letter Agreement, the Sponsor has agreed not to transfer any Founder Shares (or shares of common stock issuable upon conversion thereof) until one year after the completion of the Issuer’s partnering transaction or earlier if, subsequent to such partnering transaction, (x) the last sale price of the Series A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Issuer’s partnering transaction or (y) the Issuer consummates a subsequent liquidation, merger, stock exchange or other similar transaction that results in all of the Issuer’s stockholders having the right to exchange their shares of Series A Common Stock for cash, securities or other property. Notwithstanding the foregoing, the Letter Agreement provides exceptions pursuant to which the Sponsor can transfer such shares to certain permitted transferees as further described in the Letter Agreement. Under the Letter Agreement, neither the Private Placement Warrants nor the shares underlying such Private Placement Warrants may be transferred (except to certain permitted transferees) until 30 days after the consummation of a partnering transaction.

Under the Letter Agreement, the Sponsor also agreed that it will not propose any amendment to the Issuer’s Amended and Restated Certificate of Incorporation that would affect the substance or timing of the Issuer’s obligation to redeem the shares of Series A Common Stock underlying the Units sold in the Issuer’s IPO if the Issuer does not complete a partnering transaction within 24 months from the closing of its IPO (or 27 months from the closing of its IPO if the Issuer has executed a letter of intent, agreement in principle or definitive agreement for a partnering transaction within 24 months from the closing of its IPO) unless the Issuer provides its public stockholders with the opportunity to redeem their shares of Series A Common Stock upon approval of any such amendment.

Under the Letter Agreement, the Sponsor agreed to waive, with respect to any shares of the Series A Common Stock held by it, any redemption rights it may have in connection with the consummation of a partnering transaction, including, without limitation, any such rights available in the context of a stockholder vote to approve such partnering transaction or in the context of a tender offer made by the Issuer to purchase shares of the Series A Common Stock.

The Sponsor also agreed that in the event of the liquidation of the Trust Account of the Issuer (as defined in the Letter Agreement), it will indemnify and hold harmless the Issuer against any and all loss, liability, claim, damage and expense whatsoever to which the Issuer may become subject as a result of any claim by any third party for services rendered or products sold to the Issuer, or by any prospective target business with which the Issuer has entered into a letter of intent, confidentiality or other similar agreement for a partnering transaction, but only to the extent necessary to ensure that such loss, liability, claim, damage or expense does not reduce the amount of funds in the Trust Account to below (i) $10.00 per share of Series A Common Stock or (ii) such lesser amount per share of Series A Common Stock held in the Trust Account as of the date of the liquidation of the Trust Account, due to reductions in value of the trust assets, in each case net of the amount of interest which may be withdrawn to pay taxes; provided that such indemnity shall not apply if such third party or prospective target business executes an agreement waiving any claims against the Trust Account.

The Letter Agreement also provides for the forfeiture of certain of the Founder Shares depending on the extent to which the underwriters exercise the over-allotment option in the IPO. The underwriters have exercised the over-allotment option in full, so no Founder Shares will be forfeited.

The description of the Letter Agreement is qualified in its entirety by reference to the full text of such agreement, a copy of which is filed as an exhibit hereto.

Forward Purchase Agreement

On May 28, 2021, in connection with the Issuer’s IPO, the Issuer and the Sponsor entered into a forward purchase agreement (the “Forward Purchase Agreement”), providing for the purchase of up to 10,000,000 units of the Issuer (the “Forward Purchase Units”), subject to the terms and conditions of the Forward Purchase Agreement, with each Forward Purchase Unit consisting of one share of Series B Common Stock and one-third of one warrant to purchase one share of Series A Common Stock, for a purchase price of $10.00 per Forward Purchase Unit, in an aggregate amount of up to $100,000,000, in a private placement to occur concurrently with the closing of the Issuer’s partnering transaction.

The description of the Forward Purchase Agreement is qualified in its entirety by reference to the full text of such agreement, a copy of which is filed as an exhibit hereto.
