The Company posted a Letter to Our Shareholders on its Investor Relations website from Founder and CEO Dr. Qichao Hu and Chief Financial Officer Jing Nealis, which provides a business update, details on its fourth quarter and full year 2025 results, and its guidance for 2026.

Qichao Hu, Founder and CEO of SES AI, noted, “During 2025, we continued our transformation through the launch of the Molecular Universe platform by using SES’s expertise in AI4Science to accelerate battery development and materials discovery. We also established three separate business units in Energy Storage Systems, drones, and materials all focusing on revenue generation. Using the latest version of the Molecular Universe platform, we successfully discovered six materials breakthroughs currently being tested by 40+ customers across EVs, drones, ESS, and consumer electronics sectors. Through our joint venture with Hisun, we expect to leverage their 150,000-ton annual global capacity to produce these materials at a commercial scale for customers.”

“Our high energy density Li-Metal and Li-ion cells provide us with a large opportunity in the drone market. We recently announced we expect to convert our manufacturing capacity at our Chungju, South Korea facility from EV to drones form factor and explore greater manufacturing capacity in Southeast Asia to both meet that demand but also to be National Defense Authorization Act compliant. Additionally, through the UZ Energy acquisition, we are now well-positioned to grow our ESS business by offering customers both the hardware and software needed to predict battery health and reduce maintenance costs.

“As we look ahead to 2026, we will continue to focus on our capex-light business model to grow revenue in ESS, drones and materials. The Molecular Universe is changing material discovery in chemistry and material science, and its high quality scientific data and intuition is becoming a valuable asset to the exciting development in AI4Science,” Hu added.

Non-GAAP Financial Measures

This press release includes the use of non-GAAP financial measures, which are intended to provide supplemental information regarding our performance. These non-GAAP measures include Non-GAAP net loss and Non-GAAP gross margin.

We use these non-GAAP measures to supplement our financial reporting and to evaluate ongoing operations and results, facilitate internal planning and forecasting, and assess performance against prior periods, industry peers, and the broader market. These non-GAAP measures are not prepared in accordance with generally accepted accounting principles (GAAP) and should not be considered as an alternative to GAAP results. Industry peers and other companies may calculate similar non-GAAP measures differently. Non-GAAP financial measures have limitations, including that they exclude the impact of certain items that are included in the most directly comparable measure calculated and presented in accordance with GAAP, which adjustments reflect the exercise of judgment by management. We believe that these non-GAAP measures, when considered together with the GAAP results, provide investors with an additional understanding of our operating performance. Reconciliations of each non-GAAP financial measure to the most directly comparable GAAP financial measure can be found in the supplemental non-GAAP information section at the end of this press release.

As presented in the “Reconciliation of Non-GAAP Financial Measures” tables in our Letter to Our Shareholders , each of the non-GAAP financial measures excludes the impact of one or more of the following items for purposes of calculating non-GAAP financial measures to facilitate an evaluation of SES’s current operating performance and a comparison to its past operating performance:

Stock-based compensation expense . SES excludes the impact of stock-based compensation expense from its non-GAAP measures primarily because they are non-cash in nature. Moreover, the impact of this expense is significantly affected by SES’s stock price at the time of an award, which can be volatile and over which management has limited to no control.

Depreciation and amortization . This item represents depreciation and amortization of purchased long-lived assets and acquired intangible assets, which are both non-cash expenses. Acquisition related amortization of acquired intangible assets are not reflective of SES’s ongoing financial performance.

Interest income . This item consists primarily of interest income on short term debt securities that primarily includes accretion income from the debt securities as they progress towards their maturity date.

Benefit (provision) from income taxes . This item represents the amount adjusted to SES’s GAAP tax provision or benefit to exclude the impact of the income tax effects of GAAP adjustments that are not reflective of SES’s ongoing financial performance.

(Loss) gain on change in fair value of Sponsor Earn-Out Liability . This item represents the amount adjusted to SES’s GAAP fair value liability for Sponsor Earn-Out shares, which is a non-cash adjustment that is more tied to the change in stock price rather than management’s operational performance.

Definitions

Net loss (Non-GAAP) attributable to SES shareholders represents Adjusted EBITDA adjusted further to reinclude the impact of interest income. Adjusted EBITDA represents EBITDA adjusted to exclude the impact of loss (gain) on change in fair value of Sponsor Earn-Out liability and stock-based compensation. EBITDA represents net loss attributable to SES shareholders adjusted to exclude the impact of interest income, taxes, depreciation and amortization.
