Item 1.01. Entry into a Material Definitive Agreement.

On March 4, 2021, Haymaker Acquisition Corp. III (the “Company”) consummated its initial public offering (the “IPO”) of 30,000,000 units (the “Units”), each Unit consists of one share of Class A common stock of the Company, par value $0.0001 per share (“Class A Common Stock”), and one-fourth of one redeemable warrant of the Company (“Warrant”), with each whole Warrant entitling the holder thereof to purchase one share of Class A Common Stock for $11.50 per share. The Units were sold at a price of $10.00 per Unit, generating gross proceeds to the Company of $300,000,000. The Company granted the underwriters’ a 45-day option to purchase up to an additional 4,500,000 units to cover over-allotments, if any. On March 3, 2021, the underwriters exercised the over-allotment option in part and on March 5, 2021 purchased 1,750,000 Units, which were sold at an offering price of $10.00 per Unit, generating gross proceeds of $17,500,000.

In connection with the IPO, the Company entered into the following agreements, forms of which were previously filed as exhibits to the Company’s Registration Statement on Form S-1 (File No. 333-253010) related to the IPO, originally filed with the U.S. Securities and Exchange Commission (the “Commission”) on February 12, 2021 (as amended, the “Registration Statement”):

Item 3.02. Unregistered Sales of Equity Securities.

Simultaneously with the closing of the IPO, pursuant to the Private Placement Warrants Purchase Agreement, the Company completed the private sale of an aggregate of 5,333,333 warrants (the “Private Placement Warrants”) to the Sponsor at a purchase price of $1.50 per Private Placement Warrant, generating gross proceeds to the Company of $8,000,000. On March 5, 2021, in connection with exercise of the over-allotment option by the underwriters, the Company sold 233,333 Private Placement Warrants to the Sponsor at a purchase price of $1.50 per Private Placement Warrant, generating gross proceeds of $350,000. The Private Placement Warrants are identical to the Warrants included in the Units sold as part of the Units in the IPO, except as otherwise disclosed in the Registration Statement. No underwriting discounts or commissions were paid with respect to such sale. The issuance of the Private Placement Warrants was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended.

Item 5.03. Amendments to Certificate of Incorporation or Bylaws; Change in Fiscal Year.

On March 1, 2021, in connection with the IPO, the Company filed its Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, effective the same day. The terms of the Amended and Restated Certificate of Incorporation are set forth in the Registration Statement and are incorporated herein by reference. A copy of the Amended and Restated Certificate of Incorporation is attached as Exhibit 3.1 hereto and incorporated herein by reference.

Item 8.01. Other Events.

A total of $300,000,000, comprised of $294,000,000 of the proceeds from the IPO (which amount includes $10,500,000 of the underwriters’ deferred discount) and $6,000,000 of the proceeds of the sale of the Private Placement Warrants, was placed in a U.S.-based trust account at J.P. Morgan Chase Bank, N.A., maintained by Continental Stock Transfer & Trust Company, acting as trustee. Except with respect to interest earned on the funds held in the trust account that may be released to the Company to pay its taxes (less up to $100,000 interest to pay dissolution expenses), the funds held in the trust account will not be released from the trust account until the earliest of (i) the completion of the Company’s initial business combination, (ii) the redemption of any of the Company’s public shares properly submitted in connection with a stockholder vote to amend the Company’s amended and restated certificate of incorporation (a) to modify the substance or timing of its obligation to redeem 100% of the Company’s public shares if it does not complete its initial business combination within 24 months from the closing of the IPO or (b) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity and (iii) the redemption of the Company’s public shares if it is unable to complete its initial business combination within 24 months from the closing of the IPO, subject to applicable law.

In addition, the 8,625,000 shares of Class B common stock of the Company (the “Founder Shares”) held by the Sponsor (prior to the exercise of the over-allotment) included an aggregate of up to 1,125,000 Founder Shares subject to forfeiture by the Sponsor to the extent that the underwriters’ over-allotment option was not exercised in full, so that the Sponsor would own 20.0% of issued and outstanding common stock. As a result of the partial exercise of the over-allotment option to purchase 1,750,000 Units, the Sponsor forfeited 437,500 Founder Shares on March 5, 2021 in order to maintain ownership of 20.0% of issued and outstanding shares of the Company. The Founder Shares forfeited by the Sponsor were cancelled by the Company.

On March 1, 2021, the Company issued a press release announcing the pricing of the IPO, a copy of which is attached as Exhibit 99.1 to this Current Report on Form 8-K.

On March 4, 2021, the Company issued a press release announcing the closing of the IPO, a copy of which is attached as Exhibit 99.2 to this Current Report on Form 8-K.
