    PROPOSAL NO. 1 — ELECTION OF DIRECTORS

  2. Directors

    Directors Our stockholders will elect three Class II directors at the Annual Meeting. Each of the Class II directors is expected to hold office until the 2029 annual meeting of our stockholders, or until their respective successors are duly elected and qualified. Voting Standard Directors are elected by a plurality of the voting power of the shares present online or represented by proxy at the Annual Meeting and entitled to vote on the election of directors. This means that the three nominees who receive the most votes will be elected to the three open directorships, even if they get less than a majority of the votes cast. Proxies cannot be voted for a greater number of persons than the nominees named in this proxy statement. No cumulative voting is permitted. Plurality Plus Any director nominee who does not receive a greater number of the votes cast “for” their election than votes “withheld” for that nominee’s election shall tender their resignation to our Board promptly following certification of the stockholder vote. The governance committee will consider the tendered resignation and recommend to our Board whether to accept or reject the resignation or whether other action should be taken. Our Board will consider the recommendation and publicly disclose its decision (by press release, SEC filing, or any other public means of disclosure deemed appropriate) regarding the tendered resignation within 90 days following certification of the election results. The director who tenders their resignation may not participate in the recommendation of the governance committee or the decision of our Board with respect to their resignation. Director Nominations Our Board approved our slate of nominees at the recommendation of the governance committee. All nominees are current directors. Each nominee has consented to their nomination and has advised us that they intend to serve if elected. If, at the time of the Annual Meeting, one or more of the nominees have become unable to serve: (1) shares represented by proxies will be voted for the remaining nominees and for any substitute nominee or nominees; or (2) our Board may, in accordance with our Bylaws, reduce the size of our Board or leave a vacancy until a nominee is identified.

Base salary adjustments also allow the HRC committee to reflect individual performance, scope of the position, and/or changed responsibilities. | | | Annual Bonus | Short-term program providing named executive officers with an annual cash bonus opportunity. | Based on the HRC committee’s assessment of each named executive officer’s achievement against Company and individual operational and strategic goals and objectives. | Reward performance in attaining Company and individual performance goals on an annual basis. | | Long-Term Equity Incentive | RSUs | Long-term equity awards which provide for the delivery of shares of common stock subject to continued employment. | Alignment with stockholders through Company share price performance and the creation of stockholder value. | Align the interests of executives with those of stockholders, promote retention, and foster stock ownership. |

We do not maintain executive or supplemental retirement plans. | | No hedging or pledging permitted. We do not allow hedging or pledging by our directors, officers, or employees. |

  25. Our Objectives

    Our Objectives We believe that to be successful we must hire, motivate, and retain talented leadership. We recognize that there is significant competition for qualified executives within our industry, and it can be particularly challenging for companies to recruit executive officers of the caliber necessary to achieve our short-term operational goals and long-term strategic objectives. Accordingly, the principal objectives of our executive compensation program are to: • Attract, retain, incentivize, and reward talented and qualified individuals who share our philosophy and desire to work towards achieving our goals. • Advance the success of our Company by aligning executive incentives with the long-term interests of our stockholders. • Align compensation with corporate strategies and operational objectives. • Provide an overall level of compensation opportunity that is competitive within the markets in which we compete and within a broader group of companies of comparable size, life cycle, and complexity. Our 2025 executive compensation program continued to reflect our startup origins in that it consisted primarily of salary, annual incentives, and RSU awards, with a focus on the use of long-term equity awards that vest ratably over four years. We intend to continue to evaluate our philosophy and compensation programs as circumstances require.

  26. 2025 Named Executive Officer Compensation

    1 Ms. Heller was appointed as Chief Financial Officer and Treasurer, effective June 17, 2024. Annual Cash Bonus Each named executive officer was granted an opportunity to earn an annual cash bonus, the purpose of which was to motivate and reward achievement of key Company and individual objectives. For 2025, each named executive officer’s annual cash bonus payout was determined based on the HRC committee’s assessment of the performance of the Company and the applicable named executive officer against certain operational and strategic goals and objectives. For 2025, these goals and objectives related to continued development of our electrolyte technology, progress under our agreements with strategic partners, electrolyte sampling to potential customers, and achievement of certain production targets. For 2025, the HRC committee set a bonus target of 100% of the salary actually paid to Mr. Van Scoter and a bonus target of 60% of the salary actually paid to each other named executive officer. The HRC committee retained the discretion to pay cash bonuses higher or lower than target based on the HRC committee’s assessment of the level of achievement of the goals and objectives described above, as well as any other matters as the HRC committee deemed appropriate. These goals and objectives were designed to be challenging but attainable with strong performance. The HRC committee reviewed actual results against each of the 2025 goals and objectives. Following review and discussion, the HRC committee determined that the 2025 goals and objectives were achieved at 98% in the aggregate. The following table shows the 2025 target opportunity, payout percentage as determined by the HRC committee, and amount earned for each named executive officer:

  27. 2025 Named Executive Officer Compensation

    | Name | Target Annual Incentive Payout (% of Salary)(1) | Target Annual Incentive Payout ($)(1) | 2025 Payout Percentage Earned (% of Salary)(2) | 2025 Actual Payout ($) | | John Van Scoter | 100 | 551,079 | 98 | 544,000 | | Linda Heller | 60 | 271,846 | 98 | 270,000 | | Joshua Buettner-Garrett | 60 | 236,539 | 98 | 235,000 |

  28. 2025 Named Executive Officer Compensation

    Long-Term Incentive Program (“LTIP”) for 2025 LTIP awards are designed to provide a link to long-term stockholder value through equity awards for our executives. Under our LTIP, the HRC committee has the authority to award various forms of long-term incentive grants, such as stock option awards and RSU awards. All grants under the LTIP are made pursuant to the Solid Power, Inc. 2021 Equity Incentive Plan (the “2021 Plan”). In 2025, the HRC committee delivered a significant component of each executive officer’s total compensation in the form of equity incentive awards to align the interests of the recipients with the interests of our stockholders. Each named executive officer was provided a long-term incentive award opportunity in the form of RSUs, subject to the same vesting schedule described above. We have historically granted both stock options and RSUs to our named executive officers, but the HRC committee chose to grant the 2025 LTIP awards entirely in RSUs to minimize dilution while optimizing the retentive value of the awards. Going forward, the HRC committee will continue to evaluate the equity mix for annual grants to our named executive officers. In determining the size of these grants, the HRC committee, in consultation with Compensia, considered several factors, including the percentage ownership in the Company held by each named executive officer and the amount of their ownership interests that were unvested as of the date of grant; the estimated value of their ownership interests; market data for similarly situated executives at comparable companies; and the named executive officer’s past performance and expected future contributions. The following table shows the grant date fair value of the equity incentive awards granted to the named executive officers during 2025:

  29. 2025 Named Executive Officer Compensation

    1 The amounts in this column represent the aggregate grant date fair value of awards granted to each named executive officer, computed in accordance with the Financial Accounting Standards Board’s Accounting Standards Codification Topic 718 (“FASB ASC Topic 718”). See Note 8 to our Consolidated Financial Statements included in the Annual Report, which contains a discussion of all assumptions made by us in determining the grant date fair value of our RSUs. The actual number of RSUs were calculated using a trailing 30-day stock price average. The “grant date fair value” of the RSU award as reflected in this table represents greater than 100% of the total LTIP award because the trailing 30-day stock price average was lower than the “grant date fair value.”

  30. Equity Grant Timing Considerations

    Equity Grant Timing Considerations Equity awards are granted to executives at the discretion of the HRC committee and generally in the first quarter of the applicable year. The HRC committee may approve grants to be effective at other times, including in connection with the hiring of an executive. The HRC committee did not take material non-public information into account when determining the timing and terms of equity awards in 2025, and we do not time the disclosure of material non-public information for the purpose of affecting the value of executive compensation. In 2025, no stock options were granted to any named executive officer.

  31. Severance and Change in Control Protection

    Severance and Change in Control Protection In November 2025, our Board amended, restated, and continued the Solid Power, Inc. Executive Change in Control and Severance Plan (the “Prior Plan”) previously adopted in August 2021 in the form of two separate plans: (i) the Solid Power, Inc. Severance Benefit Plan (the “Severance Plan”) and (ii) the Solid Power, Inc. Change in Control Severance Plan for Executives (the “Executive CIC Severance Plan” and, together with the Severance Plan, the “Plans”), effective as of October 31, 2025 and November 19, 2025, respectively. The Plans supersede the Prior Plan in its entirety. Severance Plan The Severance Plan generally provides that, in the event of the termination of a named executive officer’s employment (i) by us for a reason other than cause or (ii) by the named executive officer for good reason (as such terms are defined in the Severance Plan), then the named executive officer will be entitled to the following payments and benefits: • a cash severance payment, equal to (i) 12 months of base salary in the case of Mr. Van Scoter and (ii) nine months of base salary in the case of the other named executive officers; • in the case of Mr. Van Scoter, a pro-rated annual cash bonus for the year of termination, based on actual performance for such year and payable at the same time as annual cash bonuses are paid to actively employed executives; and • reimbursement of an amount equal to the employer-paid portion of the applicable monthly premium for continued health coverage under the Consolidated Omnibus Reconciliation Act of 1985, as amended (“COBRA”), for a maximum period of (i) 12 months in the case of Mr. Van Scoter and (ii) nine months in the case of the other named executive officers. Named executive officers are not entitled to duplicative severance benefits for the same termination under multiple Company plans or policies (including the Executive CIC Severance Plan), provided that payments under any individual retention agreement will not reduce benefits otherwise payable under the Plans. Executive Change in Control and Severance Plan The Executive CIC Severance Plan generally provides that, in the event of termination of a named executive officer’s employment within a period beginning three months prior to and ending 12 months following a change in control (as defined in the Executive CIC Severance Plan) (i) by us for a reason other than cause or (ii) by the named executive officer for good reason (as such terms are defined in the Executive CIC Severance Plan), then the named executive officer will be entitled to the following payments and benefits: • a cash severance payment, equal to (i) 24 months of base salary in the case of Mr. Van Scoter and (ii) 12 months of base salary in the case of the other named executive officers; • a lump sum payment, equal to (i) 1.5x the amount of annual cash bonus in the case of Mr. Van Scoter and (ii) the amount of annual cash bonus in the case of the other named executive officers, in each case paid or payable for the calendar year immediately prior to the calendar year in which the change in control occurs; reimbursement of an amount equal to the employer-paid portion of the applicable monthly premium for continued health coverage under COBRA for a maximum period of (i) 24 months in the case of Mr. Van Scoter and (ii) 12 months in the case of the other named executive officers; and

  33. Severance and Change in Control Protection

    100% accelerated vesting of all outstanding equity awards, with all performance goals or other vesting criteria deemed to be achieved at target levels for the relevant performance period(s) with respect to performance-based equity awards. General Provisions of the Plans Receipt of the payments and benefits provided for under the Plans is conditioned on the named executive officer signing and not revoking a separation and release of claims agreement and such release becoming effective and irrevocable no later than the 60th day following the named executive officer’s qualifying termination of employment, as well as continued compliance with the invention assignment and confidentiality agreement applicable to the named executive officer. Receipt of payments and benefits under the Executive CIC Severance Plan also requires execution of a restrictive covenant agreement containing customary non-competition, non-solicitation, and non-disparagement provisions and continued compliance therewith. In addition, if any of the payments or benefits provided for under the Executive CIC Severance Plan or otherwise payable to a named executive officer would constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), and could be subject to the related excise tax, the named executive officer will receive either full payment of such payments and benefits or such lesser amount that would result in no portion of the payments and benefits being subject to the excise tax, whichever results in the greater amount of after-tax benefits to the named executive officer. The Plans do not require the Company to provide any tax gross-up payments to the named executive officers. Payments and benefits payable under the Plans that constitute non-qualified deferred compensation subject to Section 409A of the Code will not be paid until the first payroll date to occur following the 6-month anniversary of the named executive officer’s termination date. Benefits and Perquisites We provide benefits to our named executive officers on the same basis as provided to all of our employees, including medical, dental, and vision insurance, life insurance, accident insurance, short-and long-term disability insurance, a health savings account, an employee assistance program, a flexible spending account for medical, dental, and vision expenses, a dependent flexible spending account, and a 401(k) plan. Retirement Benefits We provide a tax-qualified 401(k) plan for all eligible employees, including our named executive officers, which includes a matching contribution for participants’ elective contributions to the 401(k) plan. Our 401(k) plan provides eligible employees with an opportunity to save for retirement on a tax-advantaged basis. Under our 401(k) plan, eligible employees may elect to defer a portion of their compensation, within the limits prescribed by the Code, and the applicable limits under the 401(k) plan, on a pre-tax or after-tax (Roth) basis, through contributions to the 401(k) plan. All of a participant’s deferral contributions into the 401(k) plan and any matching employer contributions are 100% vested when contributed. The 401(k) plan permits us to make discretionary nonelective employer contributions and discretionary matching employer contributions. The 401(k) plan is intended to qualify under Sections 401(a) and 501(a) of the Code. As a tax-qualified retirement plan, pre-tax contributions to the 401(k) plan and earnings on those pre-tax contributions are not taxable to the employees until distributed from the 401(k) plan, and earnings on Roth contributions generally are not taxable when distributed from the 401(k) plan. We do not provide employees, including our named executive officers, with any other retirement benefits, including tax-qualified defined benefit plans, supplemental executive retirement plans, or nonqualified defined contribution plans.

  35. COMPENSATION OF DIRECTORS

    COMPENSATION OF DIRECTORS

  36. Outside Director Compensation Policy

    Outside Director Compensation Policy The HRC committee, with the assistance of Compensia, periodically evaluates the compensation of our directors and recommends the amount of cash and equity consideration. On July 5, 2023, after considering the input of Compensia, our Board approved the amended Solid Power, Inc. Outside Director Compensation Policy (the “Outside Director Compensation Policy”), which is designed to attract, retain, and reward non-employee directors. Under the Outside Director Compensation Policy, each outside director will receive the cash and equity compensation for Board services described below. We also will reimburse our outside directors for reasonable, customary, and documented travel expenses to meetings of our Board or its committees and other reasonable expenses. Maximum Annual Compensation Limit In addition, the 2021 Plan includes a maximum annual limit of $500,000 of cash compensation and equity compensation awards that may be paid, issued, or granted to an outside director in any fiscal year (increased to $750,000 in the fiscal year of the outside director’s initial year of service as an outside director). For purposes of this limitation, the grant date fair value is determined in accordance with U.S. generally accepted accounting principles (“GAAP”) as then in effect. Any cash compensation or equity awards granted under the 2021 Plan to an outside director for their services as an employee or as a consultant (other than as an outside director) will not count for purposes of the limitation. The maximum limit does not reflect the intended size of any potential compensation or equity awards to our outside directors. Cash Compensation Our outside directors each receive an annual cash retainer fee in the amount of $50,000. Our non-executive chairperson or lead independent director, as applicable, is entitled to receive an additional $40,000 per year for their service. In addition, all of our outside directors who serve on or chair a Board committee receive the following annual committee fees:

  37. Outside Director Compensation Policy

    | Committee | Chairperson ($) | Member ($) | | Audit | 20,000 | 10,000 | | Governance and Corporate Responsibility | 15,000 | 7,500 | | Human Resources and Compensation | 15,000 | 7,500 |

  38. Outside Director Compensation Policy

    Each outside director who serves as the chairperson of a committee will receive only the annual cash fee as the chairperson of the committee and does not receive the additional annual cash fee as a member of the committee. All cash payments to outside directors are paid quarterly in arrears. Equity Compensation In addition, each outside director is awarded equity compensation as follows: Initial Awards Each individual who first becomes an outside director following the effective date of the Outside Director Compensation Policy is granted an award of RSUs (an “Initial Award”) covering a number of shares of common stock, with such Initial Award having a grant date fair value (determined in accordance with GAAP) (the “Grant Value”) of $250,000, rounded to the nearest whole share of common stock. Each Initial Award vests in twelve equal quarterly installments over a period of three years, on February 15, May 15, August 15, or November 15 of each year, subject to the outside director continuing to be a service provider through the applicable vesting date.

    Annual Award On the date of each annual meeting of stockholders, each outside director is automatically granted an award of RSUs (an “Annual Award”) covering a number of shares of common stock, with such Annual Award having a Grant Value of $145,000, rounded to the nearest whole share of common stock. Each Annual Award vests on the earlier of (i) the first anniversary of the grant date or (ii) the day before the next annual meeting of stockholders, in each case, subject to the outside director continuing to be a service provider through such vesting date. Immediately prior to a change in control (as defined in the 2021 Plan), each outside director’s outstanding awards will fully vest, subject to the outside director continuing to be a service provider through the date of the change in control.
