The business, per its filings

SEC primary

LanzaTech harnesses the power of biology and big data to create climate-safe materials and fuels. With expertise in synthetic biology, bioinformatics, artificial intelligence and machine learning coupled with engineering, LanzaTech has created a platform that converts waste carbon into new everyday products that would otherwise come from virgin fossil resources. LanzaTech's first two commercial scale gas fermentation plants have produced over 30 million gallons of ethanol, which is the equivalent of offsetting the release of over 150,000 metric tons of CO2 into the atmosphere. Additional plants are under construction globally. LanzaTech is based in Illinois, USA. For more LanzaTech company news, visit lanzatech.com. As previously announced, LanzaTech has entered into a merger agreement for a business combination transaction (the “Business Combination”) with AMCI Acquisition Corp. II (Nasdaq: AMCI) (“AMCI”). Upon closing, the combined company is expected to trade on Nasdaq under the ticker symbol “LNZA”.
