EX-99.1

Exhibit 99.1

Dear Shareholders, Our mission is to power a new era of electric transportation on land and in air with Li-Metal batteries. That new era became a lot more visible in the past few weeks as we reached two milestones that we believe no Li-Metal battery manufacturer has ever reached before. We’re excited to talk about those achievements in more detail as we believe these milestones reinforce our lead in the race to commercialize our Li-Metal technology for both EV and UAM applications. We have talked about four pillars to the business that support our mission, and we have made significant advancements in each one this year. Let’s talk about our core focus first - EV. 1. EV We have an extremely differentiated high-density battery technology platform that has been validated by JDA partners such as Hyundai, Honda, and GM. The announcement last week of our partnership with Hyundai entering the next phase further validates our technology and capability to scale manufacturing to rapidly meet increased demand. This agreement represents two global firsts for SES AI and our industry. It is the first time a Li-Metal battery manufacturer is building a line within an automotive OEM’s facility, and it makes us the only Li-Metal battery company to have two B-sample development JDAs underway. In the past few months, we have all seen coverage concerning the US OEMs scaling back their EV ambitions. However, Hyundai, already the second largest EV manufacturer in the United States, is focusing on becoming a top 3 global EV maker by 2030. They recently announced a $50-plus billion investment to increase their EV lineup to 31 models and additional personnel for research and development of new EVs and batteries. Honda announced last week that they are making a $15 billion investment in EV plants in Canada, reinforcing their commitment to very ambitious goals over the next decade.

We can’t understate the significance of moving into our next phase of the joint development contract and the confidence Hyundai have placed in SES AI’s technology and capabilities. While Hyundai will fund the development of the dedicated B-sample facility in their Electrification Research Center in Ui-Wang, South Korea, SES AI will be investing to build and operate one of the largest capacity Li-Metal lines in the world within this new facility. We expect this line to be ready in early fourth quarter of this year with our Avatar AI infrastructure ready several months thereafter. The increased production allows for more training of our Avatar AI in addition to more testing. The testing we will be conducting will be on the performance life cycle, and testing the cells to the extreme to understand where they fail. This process is similar to our other B-sample agreement but with less engineering features required. Operating this B-sample line in Hyundai’s Ui-Wang facility will be good practice for what we plan to do with C-samples and beyond – especially with the joint ventures we’ve mentioned in the past that we believe can help us support the larger scale needed for start of production. Building large automotive Li-Metal cells

2. UAM While EV is the core focus, we are very committed to urban air mobility, or UAM, as an exciting application for our lithium metal batteries. It’s the second pillar to our mission. UAM is an adjacent growth opportunity that requires little additional development beyond what we are already doing for EVs and we believe is a perfect fit for Li-Metal. By little additional development, we mean that the B-sample cells we have delivered for EV are nearly equivalent to commercial production for UAM. With two B-sample agreements going, we can transfer those learnings to UAM. UAM operates on a fleet model where revenue/passenger/mile is the primary metric and weight is a primary concern. Li-Metal’s energy density means that aircraft can carry twice the number of passengers or double the amount of cargo or double the number of miles. This step-change greatly improves UAM operators’ profitability. As a first mover in the space, it also means we have an opportunity to make this market. We’re already seeing strong demand from OEMs and have a growing number of cell sampling and supply agreements with the top five OEMs. I would also note that our partner, Hyundai, has been very aggressive and has demonstrated commitment to UAM. We have already started work on converting our EV A-sample line in Korea to a UAM-dedicated line, which we expect to complete in September. Building Li-Metal battery pack for UAM

3. AI To ensure practical safety across all our product lines, especially as we prepare for C-Sample and commercial deployment, we have significantly expanded the use of Avatar AI to monitor battery health and predict incidents. Our Li-Metal large cell Avatar AI prediction accuracy increased from just 60% in 2022 to 92% last year. Our target is 95% accuracy by year end. Ultimately, we aim to achieve a near 100% safety guarantee for EV and UAM and pioneer the foundation for using AI for future road map electrolyte development. With Avatar AI, we are building more than just a battery company, but the beginning of a superintelligent AI for electric transportation. Our new Electrolyte Foundry is now fully operational, and we can test new ideas generated by both human and AI much faster. We are curating several large molecular databases and systematically screening them using both classical physics simulation and machine learning. The goal is to map the relevant small molecular universe. We are very excited to collaborate with several leading research groups on both computation power and machine learning tools. AI for Science is the future of material discovery. SES AI integrates the world’s leading machine learning scientists, battery domain experts, and advanced chemical synthesis and cell testing facility. This gives us an ability to innovate and improve our products for EV and UAM, at a pace that is unprecedented in the industry. Data collection during cell manufacturing

4. Sustainability Lastly, we are integrating sustainability into our operations and innovation to enable supply chain efficiencies to accelerate production timelines and reduce costs. We recently announced that we will fund a new research initiative at Worcester Polytechnic Institute (WPI) to develop state-of-the-art recycling technology for lithium metal. To date, recycling for lithium-ion batteries exists at an early stage but recycling technology for Li-Metal batteries has not yet been developed. Recycling Li-Metal batteries can be critical in the reduction of the shortage of raw materials and environmental problems. Another initiative we are pursuing is working on dry electrodes that can reduce chemical solvent evaporation. We expect to announce a collaboration partner on this effort in the not-to-distant future. In a real-time example of integrating environmental efforts into our business, we recently announced SES Cares. This initiative partners with organizations monitoring forest fires and marine animal protection to power advanced drones with our Li-Metal A- and B-sample cells to collect field data to train Avatar AI. We will have more details on this initiative and our much broader sustainability strategy when we post our first sustainability report at the end of May. Lithium foil used in our Li-Metal cells 2024 Goals We noted last quarter that 2024 will be a key year in the commercialization of Li-Metal batteries, and we are very pleased with the execution on our 2024 goals. We have become the worlds’ first Li-Metal battery manufacturer to have two B-samples underway and we expect to become the first to build a line within an OEM’s facility.

With Avatar AI, we expect to have the highest number of cells being produced this year than ever before with a higher number of associated quality checks. The increase in data helps improve Avatar AI’s accuracy. As we look to accelerate future electrolyte discoveries, we are also training and developing new AI models and testing new ideas generated by these models in our secret Electrolyte Foundry. Financial Highlights and Outlook GAAP operating expenses for the first quarter were $21.3M. Cash used in operations was $9.0M and capital expenditures were $6.8M. We ended the first quarter with $319M in liquidity and continue to believe our strong balance sheet will support us as we remain on track to achieve our commercialization milestones. We remain our full-year 2024 guidance for cash usage from operations to be between $90M and $100M and for capital expenditures to be between $20M and $30M. As we continue to achieve the milestones we laid out, deepen our longstanding partnership with our OEM partners, and accelerate the speed of future electrolyte discovery, we are very focused on capital efficiency. Our priorities for 2024 are to attract top talents to support our strategic goals, build production capacities to deliver Li-Metal cells to our EV and UAM partners, and advance the use of AI for battery performance prediction as well as electrolyte material discovery as we stay at the forefront of battery material science innovation.
