Item 8.01     Other Events.

On January 28, 2026, Solid Power, Inc. (“Solid Power,” the “Company,” “we,” “us,” or “our”) announced that it had entered into a securities purchase agreement with a single sector-focused institutional investor for the purchase and sale of 17,000,000 shares of its common stock, pre-funded warrants to purchase up to an aggregate of 5,807,018 shares of common stock, and warrants (“common warrants”) to purchase up to an aggregate of 45,614,036 shares of common stock.

The common warrants will be immediately exercisable at an exercise price of $7.25 per share, and will expire seven years from issuance. Pursuant to the terms of the pre-funded warrants and common warrants, the holder may not exercise any portion of the pre-funded warrants or common warrants to the extent that the holder, together with its affiliates, would own more than 9.99% of the Company’s outstanding common stock immediately after such exercise. As of December 31, 2025, the Company had approximately 201.2 million shares of common stock outstanding.

The offering of the shares of common stock, pre-funded warrants, and common warrants was made pursuant to the Company’s effective shelf registration statement (File No. 333-290078). The closing of the offering is expected to occur on or about January 29, 2026, subject to the satisfaction of customary closing conditions. The gross proceeds from the offering are expected to be approximately $130 million, before deducting placement agent fees and other estimated offering expenses. The Company intends to use the net proceeds from the offering, together with its cash, cash equivalents, and available-for-sale securities comprising approximately $336.5 million (unaudited) of total liquidity as of December 31, 2025, for working capital purposes and general corporate purposes.

When used herein, the words “could,” “should,” “will,” “may,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project,” “plan,” “outlook,” “seek,” the negative of such terms and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words.

Except as otherwise required by applicable law, Solid Power disclaims any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date hereof. Readers are cautioned not to put undue reliance on forward-looking statements and Solid Power cautions you that these forward-looking statements are subject to numerous risks and uncertainties, most of which are difficult to predict and many of which are beyond the control of Solid Power, including the following factors: (i) risks relating to the uncertainty of the success of our research and development efforts, including our ability to achieve the technological objectives or results that our partners require and our ability to commercialize our technology in advance of competing technologies and our competitors; (ii) risks relating to our status as a research and development stage company with a history of financial losses with an expectation of incurring significant expenses and continuing losses for the foreseeable future, including execution of our business plan and the timing of expected business milestones; (iii) risks relating to the non-exclusive nature of our partnerships, our ability to secure new business relationships, and our ability to manage these relationships; (iv) our ability to negotiate and execute commercial agreements with our partners and customers on commercially reasonable terms; (v) broad market adoption of EVs and other technologies where we are able to deploy our technology, if developed successfully; (vi) our success attracting and retaining our executive officers, key employees, and other qualified personnel; (vii) our ability to protect and maintain our intellectual property, including in jurisdictions outside of the United States; (viii) our ability to secure government contracts and grants, changes in government priorities with respect to our government contracts and grants or government funding reductions or delays, and the availability of government subsidies and economic incentives; (ix) delays in the construction and operation of facilities that meet our short-term research and development and long-term electrolyte production requirements; (x) changes in applicable laws or regulations; (xi) risks relating to our information technology infrastructure and data security breaches; and (xii) risks relating to other economic, business, or competitive factors in the United States and other jurisdictions, including supply chain interruptions and changes in market conditions, and our ability to manage these risks and uncertainties. Additional information concerning these and other factors that may impact the operations and projections discussed herein can be found in the “Risk Factors” sections of Solid Power’s Annual Report on Form 10-K for the year ended December 31, 2024, Solid Power’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2025, and other documents filed by Solid Power from time to time with the Securities and Exchange Commission (the “SEC”), all of which are available on the SEC’s website at www.sec.gov.
