Explanatory Note

This Current Report on Form 8-K/A amends the Current Report on Form 8-K filed with the Securities and Exchange Commission (“SEC”) on May 10, 2021 (the “Original Form 8-K”).

As previously reported, on May 8, 2021, Star Peak Corp II, a Delaware corporation (“STPC”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with STPC II Merger Sub Corp., a Delaware corporation and wholly-owned subsidiary of STPC, and Benson Hill, Inc., a Delaware corporation (“Benson Hill”). In connection with the announcement of the entry into the Merger Agreement, the audited consolidated financial statements of Benson Hill and its subsidiaries as of December 31, 2020 and 2019, and for each of the three years in the period ended December 31, 2020 (the “Previously Furnished Financial Statements”) were furnished as Exhibit 99.4 to the Original Form 8-K and incorporated by reference into Item 7.01 thereto.

On May 10, 2021, Ernst & Young LLP (“E&Y”), Benson Hill’s independent registered public accounting firm, advised Benson Hill, which in turn advised STPC, of a typographical error in E&Y’s audit report included in the Previously Furnished Financial Statements which referred to the opinion date of Note 23 to such Previously Furnished Financial Statements as “March 10, 2021” instead of “May 10, 2021” (the “Typographical Error”). Accordingly, the Original Form 8-K is hereby amended solely to amend and restate Item 9.01 to (i) remove the Previously Furnished Financial Statements, which were furnished as Exhibit 99.4 to the Original Form 8-K, and (ii) furnish as Exhibit 99.4 hereto and incorporate by reference into Item 7.01 of the Original Form 8-K the revised audited consolidated financial statements of Benson Hill and its subsidiaries as of December 31, 2020 and 2019, and for each of the three years in the period ended December 31, 2020 (the “Financial Statements”).

Except for correcting the Typographical Error in E&Y’s audit report contained therein, the Financial Statements are otherwise unchanged from the Previously Furnished Financial Statements. The Original Form 8-K otherwise remains unchanged.

The foregoing (including the information presented in Exhibit 99.4) is being furnished pursuant to Item 7.01 and will not be deemed to be filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise be subject to the liabilities of that section, nor will it be deemed to be incorporated by reference in any filing under the Securities Act or the Exchange Act. The submission of the information set forth in Item 7.01 of the Original Form 8-K, as amended hereto, shall not be deemed an admission as to the materiality of any information in Item 7.01 of the Original Form 8-K, as amended hereto, including the information presented in Exhibit 99.4, that is provided solely in connection with Regulation FD.
