Item 1.01 Entry into a Material Definitive Agreement.

First Amendment to Business Combination Agreement

As previously announced, on November 22, 2021, Bright Lights Acquisition Corp., a Delaware corporation (“BLTS”), entered into a Business Combination Agreement (the “BCA”), by and among BLTS, Bright Lights Parent Corp., a Delaware corporation and a direct wholly owned subsidiary of BLTS (“ParentCo”), Mower Intermediate Holdings, Inc., a Delaware corporation and a direct wholly owned subsidiary of BLTS (“Intermediate Holdco”), Mower Merger Sub Corp., a Delaware corporation and a direct wholly owned subsidiary of BLTS (“Merger Sub Corp”), Mower Merger Sub 2, LLC, a Delaware limited liability company and a direct wholly owned subsidiary of Intermediate Holdco (“Merger Sub LLC”), and Manscaped Holdings, LLC, a Delaware limited liability company (“Manscaped”).

On January 10, 2022, the parties to the BCA entered into the First Amendment to Business Combination Agreement (the “BCA Amendment”). The BCA Amendment provides that each of the outstanding Company LLC Units (as defined in the BCA) and the shares issuable pursuant to the applicable earnout milestone will be treated as converted to ParentCo Class A common stock, as applicable, issued and to be taken into account in calculating the per share price for purposes of determining whether any earnout milestone has been achieved in connection with certain transactions where all or substantially all the holders of outstanding shares of ParentCo Class A common stock have such shares converted, exchanged or otherwise replaced with the right to receive cash, securities or other property. Additionally, pursuant to the BCA Amendment, the definition of “Earnout Consideration” is amended with respect to each holder of ParentCo Class A common stock and each holder of restricted stock units of ParentCo to equal a portion of the available earnout shares or the available earnout restricted stock units, respectively, as determined by the Board of Managers of Manscaped. The BCA Amendment also removes the definition of “Earnout Pro Rata Portion”. The BCA Amendment also revises the figure in Section 2.4(a) of the BCA to read “22,244,958 Company LLC Units” and amends Section 6.3(a) of the BCA such that, if the registration statement filed in connection with the parties’ business combination is not effective by February 15, 2022, Manscaped shall act in good faith to deliver to BLTS its audited financial statements as of and for the years ended December 31, 2021, as soon as reasonably practicable following such date.

The BCA Amendment is filed as Exhibit 2.1 to this Current Report on Form 8-K, and the foregoing description thereof is qualified in its entirety by reference to the full text of the BCA Amendment.

First Amendment to Sponsor Support Agreement

As previously announced, in connection with the execution of the BCA, BLTS, Sponsor, Manscaped and certain individuals set forth on Schedule I thereto entered into a Sponsor Support Agreement (the “Sponsor Support Agreement”).

On January 10, 2022, the parties to the Sponsor Support Agreement entered into the First Amendment to Sponsor Support Agreement (the “SSA Amendment”). Pursuant to the SSA Amendment, the definition of “Earnout Strategic Transaction Price,” which is the price used to determine whether the shares owned by the Sponsor that, as part of the transactions contemplated by the BCA, as amended, are to be subjected to potential forfeiture to ParentCo for no consideration until the occurrence of certain earnout vesting conditions (such shares, the “Sponsor Earnout Shares”), will vest in connection with certain transactions, was amended such that the Sponsor Earnout Shares to be issued are to be taken into account when determining the Earnout Strategic Transaction Price.

The SSA Amendment is filed as Exhibit 10.1 to this Current Report on Form 8-K, and the foregoing description thereof is qualified in its entirety by reference to the full text of the SSA Amendment.

These statements are based on various assumptions, whether or not identified in this Current Report on Form 8-K. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by an investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of ParentCo, BLTS and Manscaped. Many factors could cause actual future events to differ from the forward-looking statements in this Current Report on Form 8-K, including but not limited to: (i) the risk that the transaction may not be completed in a timely manner or at all, which may adversely affect the price of BLTS’s securities, (ii) the risk that the transaction may not be completed by BLTS’s business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by BLTS, (iii) the failure to satisfy the conditions to the consummation of the transaction, including the approval by the stockholders of BLTS, the satisfaction of the minimum trust account amount following any redemptions by BLTS’s public stockholders and the receipt of certain governmental and regulatory approvals, (iv) the inability to complete the PIPE investments, (v) the occurrence of any event, change or other circumstance that could give rise to the termination of the BCA, (vi) the effect of the announcement or pendency of the transaction on Manscaped’s business relationships, operating results, and business generally, (vii) risks that the transaction disrupts current plans and operations of Manscaped and potential difficulties in Manscaped employee retention as a result of the transaction, (viii) the outcome of any legal proceedings that may be instituted against Manscaped or against ParentCo or BLTS related to the BCA or the transaction, (ix) the ability to maintain the listing of BLTS securities on the Nasdaq Stock Market or New York Stock Exchange, (x) volatility in the price of BLTS’s securities, (xi) changes in competitive and regulated industries in which Manscaped operates, variations in operating performance across competitors, changes in laws and regulations affecting Manscaped’s business and changes in the combined capital structure, (xii) the ability to implement business plans, forecasts, and other expectations after the completion of the transaction, and identify and realize additional opportunities, (xiii) the potential inability of Manscaped to increase its production capacity or to achieve efficiencies regarding its production process or other costs, (xiv) the enforceability of Manscaped’s intellectual property, including its patents and trademarks and the potential infringement on the intellectual property rights of others, (xv) the risk of downturns and a changing regulatory landscape in the highly competitive industry in which Manscaped operates, and (xvi) costs related to the transaction and the failure to realize anticipated benefits of the transaction or to realize estimated pro forma results and underlying assumptions, including with respect to estimated stockholder redemptions. These risks and uncertainties may be amplified by the COVID-19 pandemic, which has caused significant economic uncertainty. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of BLTS’s Quarterly Reports on Form 10-Q, the registration statement that includes a proxy statement/prospectus on Form S-4 that ParentCo and BLTS expect to file with the SEC and other documents filed by ParentCo and BLTS from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and Manscaped, ParentCo and BLTS assume no obligation and do not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. None of Manscaped, BLTS or ParentCo gives any assurance that any of them will achieve its expectations.
