"We are very excited by the tremendous opportunities presented by LanzaTech as its CCT technology is deployed at scale."

"We are thrilled to complete this transaction, partnering with Nimesh Patel and the AMCI team and take the next steps towards accelerating the wide-spread deployment of our commercially scaled, CCT technology and ultimately the development of the circular carbon economy our world needs." said Jennifer Holmgren, Chairwoman and CEO of LanzaTech. "We believe that the completion of the transaction and our status as a new public company will help facilitate our ambitious growth plans and accelerate the validation and, ultimately, the deployment of our revolutionary CCT technology in the eyes of the market."

Commercially Scaled Technology to Implement the Circular Carbon Economy of Tomorrow

LanzaTech's gas fermentation technology is designed to provide a profitable pathway for alleviating the significant carbon problem of heavy industry and manufacturing. Through technology and applications that are designed to touch multiple points of carbon use, LanzaTech believes it can offer a solution which could be a meaningful contributor to solving the global carbon crisis. LanzaTech's scalable technology is designed to enable participants in many industries to reduce their carbon footprint and overall environmental impact in a profitable way and to help end users replace materials made from virgin fossil resources with materials made from recycled carbon. LanzaTech helps customers create a more sustainable future by supporting customers' ESG goals and helping industries meet mandated emissions reduction targets.

Since its inception in 2005, LanzaTech has scaled proprietary bio-reactors for its novel fuels and chemical production process, using waste carbon emissions as a feedstock. With three commercial facilities using its technology and over 1,250 patents covering multiple aspects of the technology platform, LanzaTech's vision is to create a just energy transition for all.

LanzaTech, along with LanzaJet, Inc., a key partner focused on the production of sustainable aviation fuel, has built a roster of customers, partners and investors from a wide variety of industries that range from steel producers, including ArcelorMittal, and traditional energy companies, such as Suncor Energy and Shell, to aviation companies including All Nippon Airways, British Airways and Virgin Atlantic, commercially validating the technology in a number of different applications and illustrating a high degree of confidence and adoption across numerous industries.

LanzaTech Helping Pave the Road to Net-Zero

Using a variety of waste feedstocks, LanzaTech's technology platform highlights a future in which consumers are not dependent on virgin fossil feedstocks in their daily lives. LanzaTech's goal is to challenge and change the way the world uses carbon, enabling a new circular carbon economy in which carbon is reused rather than wasted, skies and oceans are kept clean, and pollution becomes a thing of the past.

LanzaTech's capital-light, licensing-driven business model not only enables LanzaTech to significantly accelerate the deployment of its patent-protected technology, but also creates a global opportunity unencumbered by geography.

Continued Commercial Momentum Built During Challenging Year for Broader Market

Since the announcement of the proposed business combination on March 8, 2022, LanzaTech NZ, Inc has continued to make significant strides, both commercially and technologically. Over the course of the past year, LanzaTech NZ, Inc has achieved a number of notable commercial wins and announced several significant technology advancements. These include the opening of the third commercial scale plant in China using LanzaTech NZ, Inc's technology, as well as several new commercial partnerships, further validating LanzaTech NZ, Inc's technology across a wide array of end markets and applications. Some of the most notable developments announced by LanzaTech NZ, Inc during 2022 include:

• Twelve and LanzaTech Partner to Create Ethanol From CO2 (March 03, 2022) ? LanzaTech NZ, Inc. and carbon transformation company Twelve announced the transformation of CO2 emissions into ethanol as part of an ongoing research and development partnership. Eliminating fossil fuels from ethanol production by converting CO2 to CO through Twelve's carbon transformation technology, and subsequently using LanzaTech NZ, Inc.'s small Continuous Stirred Tank Reactor (CSTR) to convert CO to ethanol, eliminates the use of feedstocks otherwise used as food from the ethanol production process.
• Renewable Propane Partnership with SHV Energy (March 23, 2022) ? LanzaTech NZ, Inc and SHV Energy announced a strategic partnership to employ LanzaTech NZ, Inc's CCT technology to bring renewable propane and other sustainable fuels to the market via existing and novel pathways.

The two companies partnered to co-develop the first dedicated end-of-life tire recycling process leveraging LanzaTech NZ, Inc's proprietary CCT technology and creating a pathway toward tire material circularity and the decarbonization of new tire production.
• Method to Produce Sustainable PET Bottles from Captured Carbon Discovered (May 26, 2022) ? LanzaTech NZ, Inc and Danone led a consortium which discovered a new route to monoethylene glycol, (MEG), which is a key building block for polyethylene terephthalate, resin, fibers and bottles. The technology converts carbon emissions from steel mills or gasified waste biomass directly into MEG.
• LanzaTech and Brookfield Form Strategic Partnership with an Initial $500 Million Commitment (October 3, 2022) ? Funding partnership with Brookfield Renewable, and its institutional partners to co-develop and build new commercial-scale production plants that will employ LanzaTech's CCT technology.
• LanzaTech Produces Ethylene from CO2 (October 11, 2022) ? Breakthrough discovery successfully engineering specialized biocatalysts to directly produce ethylene from CO2 in a continuous process.
• LanzaTech and Woodside Energy Announce Strategic Collaboration (October 24, 2022) ? Collaboration with Woodside Energy in which Woodside will design, construct, own, maintain and operate pilot facilities relating to LanzaTech's technologies.
• LanzaTech Announced as a Finalist for the Earthshot Prize Awards (November 4, 2022) ? Launched in 2020 by HRH Prince William, The Earthshot Prize is the world's most prestigious environmental prize.
