On July 14, 2021 (the “Closing Date”), Landcadia Holdings III, Inc., a Delaware corporation (“Landcadia” and after the Business Combination described herein renamed “Hillman Solutions Corp.”, the “Company”), consummated the previously announced business combination (the “Closing”) pursuant to the terms of the Agreement and Plan of Merger, dated as of January 24, 2021 (as amended on March 12, 2021, and as it may be further amended or supplemented from time to time, the “Merger Agreement”), by and among Landcadia, Helios Sun Merger Sub, a wholly-owned subsidiary of Landcadia (“Merger Sub”), HMAN Group Holdings Inc., a Delaware corporation (“Hillman Holdco”) and CCMP Sellers’ Representative, LLC, a Delaware limited liability company in its capacity as the Stockholder Representative thereunder (the “Stockholder Representative”). Pursuant to the terms of the Merger Agreement, Merger Sub merged with and into Hillman Holdco with Hillman Holdco surviving the merger as a wholly owned subsidiary of the Company, which was renamed “Hillman Solutions Corp.” (the “Merger” and together with the other transactions contemplated by the Merger Agreement, the “Business Combination”).

On July 29, 2021, the Audit Committee of the board of directors of the Company approved the engagement of KPMG LLP (“KPMG”) as the Company’s independent registered public accounting firm to audit the Company’s consolidated financial statements for the year ended December 31, 2021 and dismissed Marcum LLP (“Marcum”) as the Company’s independent registered public accounting firm.

The reports of Marcum on Landcadia’s financial statements as of and for the fiscal years ended December 31, 2020 and December 31, 2019 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During Landcadia’s fiscal years ended December 31, 2020, December 31, 2019 and during the subsequent interim period through July 29, 2021, the date of dismissal of Marcum, there were no disagreements between Landcadia or the Company and Marcum on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure.

During Landcadia’s fiscal year ending December 31, 2020, December 31, 2019 and during the subsequent interim period through July 29, 2021, the date of dismissal of Marcum, there were no “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934, as amended) other than the material weakness in internal controls identified by management related to evaluating complex accounting issues, issued in connection with Landcadia’s initial public offering, which resulted in the restatement of Landcadia’s financial statements as set forth in Landcadia’s Form 10-K/A for the year ended December 31, 2020, as filed with the SEC on May 3, 2021.

The Company has provided Marcum with a copy of the foregoing disclosures and has requested that Marcum furnish the Company with a letter addressed to the SEC stating whether it agrees with the statements made by the Company set forth above. A copy of Marcum’s letter dated July 29, 2021 is filed as Exhibit 16.1 to this Current Report on Form 8-K.
