Dear Ms. Yale:

Hennessy Capital Acquisition Corp. IV (the “Company,” “Hennessy Capital,” “we,” “our” or “us”) hereby transmits its response to the comments of the staff (the “Staff”) of the Division of Corporation Finance of the Securities and Exchange Commission contained in the Staff’s letter dated November 5, 2018 (the “Letter”) regarding the above-referenced Registration Statement on Form S-1 (the “Registration Statement”). For ease of reference, the numbered paragraphs below correspond to the numbered comments in the Letter, with the Staff’s comments presented in bold italics font type.

The responses below follow the sequentially numbered comments from the Letter. All page references in the responses set forth below refer to page numbers in the marked version of the Registration Statement. Capitalized terms used but not otherwise defined herein have the meanings ascribed to such terms in the Registration Statement.

Amendment No. 1 to Draft Registration Statement on Form S-1

Summary, page 1

We note the added disclosure on page 24 concerning a $500,000 fee payable to your Chief Operating Officer. Please revise the Summary on page 5 to highlight this incentive payment.

We have revised the summary of the Registration Statement (page 3) in response to the Staff’s comment.

Underwriting (Conflicts of Interest), page 143

We acknowledge your response to prior comment 15, and your revised disclosure that Nomura will be paid a market-based commitment fee on the gross proceeds from the sale of the forward purchase shares upon the announcement of a definitive agreement for your initial combination. Please revise to disclose the amount of the fee. Additionally, as noted in our prior comment, please revise the table on page 144 to disclose the value of the forward purchase agreement.

We hereby advise the Staff that Nomura will no longer receive a commitment fee based on the gross proceeds from the sale of the forward purchase shares. Instead, Nomura will receive a fixed fee of $2.5 million with respect to its commitment under the forward purchase agreement. Accordingly, we have revised the table in the Registration Statement (page 150) to disclose that commitment fee in response to the Staff's comment.
