Letter to Our Shareholders

Letter to Our Shareholders

Dear Shareholders,

On February 4, 2022, we listed on the New York Stock Exchange under the ticker symbol of “SES” for our common stock. While the global markets have been turbulent, we are confident in our business plan and expect to achieve several milestones in 2022 which include delivering the world’s first A-Sample lithium-metal battery (Li-Metal) to our OEM partners.

$450M of Cash on Our Balance Sheet at Transaction Close This includes contributions from key strategic investors including Honda, Hyundai, General Motors, Geely Auto, Kia Corporation, SAIC Motors, Foxconn, Koch Strategic Platforms, LG, SK, Temasek, and Vertex Ventures. We believe this cash will position us to get to commercialization with multiple OEMs in the next few years.

3 A-Sample JDAs and Industry Confidence We entered A-Sample joint development agreements (JDAs) in 2021, with GM (February), Hyundai (May), and Honda (December). These were the world’s first, second and third A-sample JDAs in Li-Metal. These major car manufacturers are attracted to SES because of our realistic, practical, and data-driven culture. Most OEMs thought Li-Metal was just R&D, but when they saw the world’s first 100+ Ah Li-Metal battery with 417 Wh/kg and 935 Wh/L, capable of high-rate discharge at room temperature, our practical approach to control mossy lithium formations with high concentration solvent-in-salt electrolyte, protective anode coating, and algorithm– it all became real. Going forward, we will work with our OEM partners to further test and improve cell performance and safety. Other carmakers have seen these results as well and are warming up to our practical approach to Li-Metal batteries.

Expansion At our first Battery World event held last year, we announced construction of Shanghai Giga, which is our 1GWh pilot facility. Phase I of Shanghai Giga will be completed and ready-to-use (“RTU”) in March 2022. We also began construction of a SES Korea facility in South Korea. We will start testing and delivering the world’s first Li-Metal A-Sample prototype cells and provide data to our current OEM partners and other potential future partners. By combining the R&D breakthroughs at our SES Boston HQ with the supply chain and manufacturing efficiency of Shanghai Giga and SES Korea, we are confident in our ability to deliver for our OEM partners.

Technology We made exciting progress in each of our three core technology areas:

  1. Hermes: platform for new material development. From 2012 to 2020, we developed only 4 generations (Gen 1 to Gen 4) of high concentration solvent-in-salt electrolytes. However, since 2020, we have developed 8 new generations, and now we are up to Gen 12. With each generation, we have improved the electrolyte’s Coulombic Efficiency for lithium plating on our anode, achieved a more improved balance between performance and safety, and are one step closer to meeting the complex envelopes of requirements of our current and prospective OEM partners.
  2. Apollo: engineering capability for large automotive cells. We continue to ramp up our anode coating and cell manufacturing quality and testing capabilities for Li-Metal A-Samples in Shanghai Giga and SES Korea.
  3. Avatar: AI-powered software to monitor battery health. We want to predict 100% of potential safety incidents by precisely monitoring every component and step of the entire process. We began laying the foundation to do this with new health monitoring and safety algorithms, new sensors in packs and on our manufacturing lines as well as other steps we will reveal in the future.


Supply Chain As we continue to make progress with our A-Samples, we expect to transition to B-Samples, C-Samples, and, ultimately, intend to secure purchase orders and begin production. Our supply chain will be critical to commercialization of our products:

  1. Lithium anode is a key material in our Li-Metal battery. We are partnering with suppliers to develop low-cost scalable production processes ranging from extrusion to lamination, vacuum evaporation, electrodeposition, and coating.
  2. Salt is a key component in our Li-Metal battery electrolyte. We are partnering with vendors to secure our supplies.
  3. Separator is another key component, and we recently secured an exclusive supply agreement with ENTEK Membranes, a US-based global leader in separator technology.
  4. Raw materials: Lithium and nickel are critical materials for electric vehicle (“EV”) batteries. Most of the world’s production of lithium and nickel for the first half of this decade have already been reserved by battery and auto OEMs. We are working with several partners, including certain shareholders, to secure long-term offtake agreements starting mid-decade as we prepare for the production of our B-Samples and beyond.


Beyond The EV battery industry is changing rapidly, and the global competition for supply chain dominance among battery and auto OEMs is intensifying. Tomorrow’s EV battery companies will be very different from today’s EV battery companies. The industry is experiencing an explosive growth in EV battery capacity from 10s of GWhs to 100s and 1,000s of GWhs. Battery capacity explosion leads to data explosion, which leads to intelligence explosion. We are witnessing the shattering of the industry’s old limits set by human understanding and the replacement of new limits set by the laws of physics. We believe that we can synthesize all of this data from mines, battery materials, batteries, vehicle integration, data and software, and recycling, and apply it to a super intelligence system that can redesign and improve its software and hardware.

A fascinating journey awaits. This is just the beginning.
