General 16. We note your response to our prior comments 13 and 32. Based on these responses and your current disclosure, it appears to us that a majority of LanzaTech's current commercial operations are located in China. For instance, it appears that the six projects under development in Belgium, the United States, China, Japan, Canada, and India are not material to LanzaTech s current operations. In this regard, we also note your response that the ArcelorMittal steel mill in Ghent, Belgium is currently under construction. We Nimesh Patel FirstName LastNameNimesh AMCI Acquisition Corp. II Patel Comapany 4, November NameAMCI 2022 Acquisition Corp. II November Page 5 4, 2022 Page 5 FirstName LastName also note the following disclosure on page 75: "While we are headquartered in the United States and our executive team sits in Chicago, Illinois, we have significant business operations in China. This includes a minority ownership stake in a joint venture, several strategic investors located in China, including Sinopec, and a core team of technical, business and administrative professionals at a LanzaTech office in Shanghai, which support the ongoing operations and further growth of the business in China. We license our technology in China, and our low carbon ethanol is currently being produced at three commercial scale facilities operated by our partners using our process technology, which, in addition to its use as fuel, is transported and processed for use in consumer products. Meanwhile, several additional facilities are being engineered and constructed." In light of the above, please either provide a detailed analysis, discussing both quantitative and qualitative factors, supporting your determination that LanzaTech does not have a majority of its current operations in China, or revise your registration statement to address each of the comments from the Division of Corporation Finance s Sample Letter to China- Based Companies issued by the Staff in December 2021. To the extent you do not believe a comment is applicable, please explain why such is the case in your response letter. 17. We note your response to comment 53. Please additionally provide us with the February 19, 2021 engagement letter between Barclays and LanzaTech in which LanzaTech engaged Barclays to act as its financial advisor and capital markets advisor in connection with the possible sale of LanzaTech s business to a SPAC. 18. With a view toward disclosure, please tell us whether your sponsor is, is controlled by, has any members who are, or has substantial ties with, a non-U.S. person. Please also tell us whether anyone or any entity associated with or otherwise involved in the transaction, is, is controlled by, or has substantial ties with a non-U.S. person. If so, please revise your filing to include risk factor disclosure that addresses how this fact could impact your ability to complete your initial business combination. For instance, discuss the risk to investors that you may not be able to complete an initial business combination with a target company should the transaction be subject to review by a U.S. government entity, such as the Committee on Foreign Investment in the United States (CFIUS), or ultimately prohibited. Further, disclose that the time necessary for government review of the transaction or a decision to prohibit the transaction could prevent you from completing an initial business combination and require you to liquidate. Disclose the consequences of liquidation to investors, such as the losses of the investment opportunity in a target company, any price appreciation in the combined company, and the warrants, which would expire worthless.
