PROXY STATEMENT OF SOLID POWER, INC.

GENERAL INFORMATION

This proxy statement (the “Proxy Statement”) and the accompanying proxy card are being furnished to you in connection with the 2022 Annual Meeting of Stockholders (the “Annual Meeting”) of Solid Power, Inc. (“Solid Power,” “we,” “us,” “our,” or the “Company”) for the purposes set forth in this Proxy Statement. The Annual Meeting will be held virtually on May 25, 2022, at 10:00 a.m., Mountain Time.

Solid Power, Inc. was formed upon the closing of the business combination (the “Business Combination”) of Solid Power Operating, Inc. (“Legacy Solid Power”) with Decarbonization Plus Acquisition Corporation III, a special purpose acquisition company, on December 8, 2021 (the “Closing Date”). On the Closing Date, the Company changed its name from “Decarbonization Plus Acquisition Corporation III” to “Solid Power, Inc.” Decarbonization Plus Acquisition Corporation III prior to the Business Combination is referred to herein as “DCRC.” Throughout this Proxy Statement, the term “Board” or “Board of Directors” refers to the Board of Directors of DCRC prior to the Business Combination and to our Board of Directors following the Business Combination. The board of directors of Legacy Solid Power is referred to as “Legacy Solid Power Board.” “Legacy Solid Power Common Stock” refers to Legacy Solid Power’s common stock, par value $0.0001 per share, which was canceled and converted into the right to receive Class A common stock, par value $0.0001 per share, of DCRC in connection with the Business Combination.

This Proxy Statement is expected to be provided on or about April 15, 2022, to holders of record at the close of business on March 31, 2022 (the “Record Date”) of our common stock, $0.0001 par value per share (the “Common Stock”).

Your proxy is being solicited by our Board of Directors. Your proxy may be revoked by written notice given to our Secretary at our headquarters at any time before being voted. You may also revoke your proxy by submitting a proxy with a later date or by voting during your virtual attendance at the Annual Meeting. To vote online or by telephone, please refer to the instructions included with the proxy card. To vote by mail, please complete the accompanying proxy card and return it to us as instructed in the accompanying proxy card. Votes submitted online or by telephone or mail must be received by 11:59 p.m., Mountain Time, on May 24, 2022. Submitting your vote online or by telephone or mail will not affect your right to vote virtually during the Annual Meeting, if you choose to do so. Proxies that are properly delivered to us and not revoked before the closing of the polls during the Annual Meeting will be voted for the proposals described in this Proxy Statement in accordance with the instructions set forth in the accompanying proxy card. The Board is currently not aware of any matters proposed to be presented at the Annual Meeting other than the election of three Class I directors and the ratification of Ernst & Young, LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022. If any other matter is properly presented at the Annual Meeting, the persons named in the accompanying proxy card will have discretionary authority to vote on that matter. Your virtual presence at the Annual Meeting does not of itself revoke your proxy.

Notice and Access

In accordance with the rules of the U.S. Securities and Exchange Commission (the “SEC”), we are using the Internet as our primary means of furnishing proxy materials to stockholders. Consequently, many stockholders will not receive paper copies of our proxy materials. We will instead send these stockholders a Notice of Internet Availability of Proxy Materials (the “Notice”) with instructions for accessing the proxy materials, including this Proxy Statement and annual report on Form 10-K (the “Annual Report”), and voting via the Internet. The Notice also provides information on how stockholders may obtain paper copies of our proxy materials if they so choose. This makes the proxy distribution process more efficient and less costly, and helps conserve natural resources. If you previously elected to receive our proxy materials electronically, these materials will continue to be sent via email unless you change your election.

Attendance at the Meeting

This year’s Annual Meeting will be held entirely online for the convenience of our stockholders and to support the health and well-being of our partners, employees and stockholders. Stockholders of record as of the Record Date will be able to attend and participate in the Annual Meeting online by accessing

TABLE OF CONTENTS

https://www.cstproxy.com/solidpower/2022. To join the Annual Meeting, you will need to have your control number, which is included on your Notice and your proxy card. Even if you plan to attend the Annual Meeting online, we recommend that you also vote by proxy as described herein so that your vote will be counted if you decide not to attend the Annual Meeting. If you hold your position through a bank or broker and would like to join the meeting and vote or ask a question, you will need to supply Continental Stock Transfer with a legal proxy by calling them at 917-262-2373, or proxy@continentalstock.com in order to obtain a control number. Any stockholder may attend, listen, vote and ask a question during the virtual meeting with a valid control number.

Access to the Audio Webcast of the Annual Meeting

The live audio webcast of the Annual Meeting will begin promptly at 10:00 a.m., Mountain Time. Online access to the audio webcast will open approximately 15 minutes prior to the start of the Annual Meeting to allow time for you to log in and test the computer audio system. We encourage our stockholders to access the meeting prior to the start time.

To attend the online Annual Meeting, log in at https://www.cstproxy.com/solidpower/2022. Stockholders will need their control number, which appears on the Notice and your proxy card. If you do not have a control number, please contact your broker, bank, or other nominee as soon as possible, so that you can be provided with a control number and gain access to the meeting.

Submitting Questions at the Virtual Annual Meeting

As part of the Annual Meeting, we will hold a live question and answer session, during which we intend to answer questions submitted during the meeting via the Q&A tool in accordance with the Annual Meeting’s Rules of Conduct (“Rules of Conduct”) that are pertinent to the Company and the meeting matters, as time permits. Questions and answers will be grouped by topic and substantially similar questions will be grouped and answered once.

The Rules of Conduct will be posted on https://www.cstproxy.com/solidpower/2022 approximately one week prior to the date of the Annual Meeting.

Availability of Live Webcast to Team Members and Other Constituents

The live audio webcast will be available to not only our stockholders but also our team members and other constituents.

Annual Meeting Technical Assistance

Beginning 15 minutes prior to the start of and during the virtual Annual Meeting, we will have a support team ready to assist stockholders with any technical difficulties they may have accessing or hearing the virtual meeting. If you encounter any difficulties accessing or hearing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the virtual stockholder meeting log-in page.

Securities Entitled to Vote

Stockholder of Record. If your shares are registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, you are considered the “stockholder of record,” with respect to those shares. The Notice will be sent to you by mail directly by us. As a stockholder of record, you may vote virtually in person at the Annual Meeting or vote by proxy. Whether or not you plan to attend the Annual Meeting virtually, we urge you to vote on the Internet or by phone as instructed in the Notice or by proxy by mail by requesting a paper copy of the proxy materials as instructed in the Notice to ensure your vote is counted.

Beneficial Owner. If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the “beneficial owner” of shares held in street name. The organization holding

TABLE OF CONTENTS

your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker, bank, or other agent on how to vote the shares in your account. Your brokerage firm, bank, or other agent will not be able to vote in the election of directors unless they have your voting instructions, so it is very important that you indicate your voting instructions to the institution holding your shares.

Only stockholders of record at the close of business on the Record Date are entitled to notice of the Annual Meeting. Such stockholders may vote shares held by them at the close of business on the Record Date at the Annual Meeting. As of the close of business on the Record Date, there were 173,770,952 shares of Common Stock issued and outstanding. The Common Stock is the only outstanding class of capital stock of the Company with voting rights. The Common Stock votes as a single class, with each share of Common Stock entitled to one vote on each matter to be considered at the Annual Meeting.

As a beneficial owner of shares, you are also invited to attend the Annual Meeting virtually. However, since you are not the stockholder of record, you may not vote your shares in person at the Annual Meeting unless you request and obtain a valid proxy from your broker, bank, or other agent.

Matters Scheduled for a Vote

There are two matters scheduled for a vote:

•

Proposal 1: To elect three Class I directors named in this Proxy Statement with terms to expire at the 2025 Annual Meeting of Stockholders; and

•

Proposal 2: To ratify the selection of Ernst & Young, LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2022.

Aside from the election of directors and the ratification of the selection of our independent registered public accounting firm, our Board of Directors knows of no other matters to be presented at the Annual Meeting. If any other matter is properly brought before the Annual Meeting, shares represented by all proxies received by our Board of Directors will be voted with respect thereto in accordance with the judgment of the persons appointed as proxies.

Board of Directors Voting Recommendation

Our Board of Directors recommends that you vote your shares:

•

“For” the election of all three Class I director nominees; and

•

“For” the ratification of the selection of Ernst & Young, LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2022.

How to Vote

For Proposal 1, you may vote “For” or you may “Withhold” your vote with respect to each nominee to the Board of Directors. For Proposal 2, you may vote “For,” “Against,” or abstain from voting. The procedures for voting are outlined below.

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record as of the Record Date, you may vote during the Annual Meeting by attending the Annual Meeting online and following the instructions posted at https://www.cstproxy.com/solidpower/2022, by proxy over the Internet, or by phone by following the instructions provided in the Notice, or, if you request printed copies of the proxy materials by mail, you may vote by mail. If your proxy is properly executed in time to be voted at the Annual Meeting, the shares represented by the proxy will be voted in accordance with the instructions you provide. Whether or not you plan to attend the Annual Meeting virtually, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Annual Meeting virtually and vote during the Annual Meeting if you have already voted by proxy.

TABLE OF CONTENTS

To vote during the Annual Meeting, follow the instructions posted at https://www.cstproxy.com/solidpower/2022. You will be asked to provide the control number, located on the Notice or proxy card, and follow the instructions.

To vote on the Internet, go to https://www.cstproxy.com/solidpower/2022 to complete an electronic proxy card. You will be asked to provide the control number, located on the Notice or proxy card, and follow the instructions. Your vote must be received by 11:59 p.m., Mountain Time, on May 24, 2022 to be counted.

To vote by phone, request a paper or email copy of the proxy materials by following the instructions on the Notice and call the number provided with the proxy materials to transmit your voting instructions. Your vote must be received by 11:59 p.m., Mountain Time, on May 24, 2022 to be counted.

To vote by mail, request a paper copy of the proxy materials by following the instructions on the Notice and complete, sign, and date the proxy card enclosed with the paper copy of the proxy materials and return it promptly in the envelope provided. If you return your signed proxy card to us before the Annual Meeting, we will vote your shares as you direct.

Beneficial Owner: Shares Registered in the Name of a Broker, Bank, or Other Agent

If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a notice and voting instructions from that organization rather than from us. Simply follow the instructions to ensure that your vote is counted. To vote in person at the Annual Meeting you must obtain a valid proxy from your broker, bank, or other agent. Follow the instructions from your broker, bank, or other agent included with the notice, or contact your broker, bank, or other agent.

We provide Internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your Internet access, such as usage charges from Internet access providers and telephone companies.

Broker Non-Votes

If a beneficial owner of shares held in the name of a broker, bank, or other agent does not provide voting instructions on matters deemed to be “non-routine” under Nasdaq rules, the broker, bank or other such agent cannot vote the beneficial owner’s shares on such “non-routine” matters. These un-voted shares are treated as “broker non-votes” in respect of these “non-routine” matters. Proposal 1 is considered to be “non-routine” under Nasdaq rules, and we therefore expect broker non-votes on this proposal. Because Proposal 2 is considered “routine” under Nasdaq rules, we do not expect broker non-votes on this proposal.

Vote Required

In accordance with our Amended and Restated Bylaws (the “Bylaws”), the presence at the Annual Meeting, in person or by proxy, of the holders of a majority of the total voting power of the capital stock of the Company issued and outstanding and entitled to vote shall constitute a quorum for the transaction of business at the Annual Meeting.

Directors are elected by a plurality of the voting power of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. No cumulative voting is permitted. The three nominees receiving the highest number of votes cast “for” will be elected.

The affirmative vote of a majority of the votes cast affirmatively or negatively at the Annual Meeting is required to approve the ratification of the appointment of Ernst & Young, LLP as our independent registered public accounting firm. The total number of votes cast “for” will be counted for purposes of determining whether sufficient affirmative votes have been cast to approve the ratification of the appointment of Ernst & Young, LLP as our independent registered public accounting firm.

TABLE OF CONTENTS

How to Change Your Vote After Submitting Proxy

You can revoke your proxy at any time before the final vote at the Annual Meeting. If you are a stockholder of record, you may revoke your proxy in any one of three ways:

A duly executed proxy card with a later date or time than the previously submitted proxy;

A written notice that you are revoking your proxy to our Secretary, James Liebscher, c/o Solid Power, Inc., 486 S. Pierce Avenue, Suite E, Louisville, CO 80027; or

A later-dated vote on the Internet or by phone or a ballot cast online during the Annual Meeting (simply virtually attending the Annual Meeting will not, by itself, revoke your proxy).

If you are a beneficial owner, you may revoke your proxy by submitting new instructions to your broker, bank, or other agent, or if you have received a proxy from your broker, bank, or other agent giving you the right to vote your shares at the Annual Meeting, by attending the meeting virtually and voting during the meeting.

How to Submit Stockholder Proposals for Next Year’s Annual Meeting

Pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), some stockholder proposals may be eligible for inclusion in our 2023 proxy statement. Any such proposal must be submitted in writing by December 16, 2022 to our Secretary, James Liebscher, c/o Solid Power, Inc., 486 S. Pierce Avenue, Suite E, Louisville, CO 80027. If we change the date of our 2023 Annual Meeting by more than 30 days from the one-year anniversary of the 2022 Annual Meeting, the deadline shall be a reasonable time before we begin to print and send our proxy materials. Stockholders interested in submitting such a proposal are advised to contact knowledgeable counsel with regard to the detailed requirements of the applicable securities laws and our Bylaws. The submission of a stockholder proposal does not guarantee that it will be included in our proxy statement.

Our Bylaws also establish an advance notice procedure for stockholders who wish to nominate a director or who wish to present a proposal before an annual meeting of stockholders but do not intend for the proposal to be included in our proxy statement. Our Bylaws provide that if you wish to submit a proposal that is not to be included in next year’s proxy statement or nominate a director, a timely written notice of a stockholder proposal must be delivered to, or mailed and received by our Secretary, James Liebscher, c/o Solid Power, Inc., 486 S. Pierce Avenue, Suite E, Louisville, CO 80027, no earlier than January 25, 2023 and no later than the close of business on February 24, 2023, which notice must contain the information specified in our Bylaws. If we change the date of our 2023 Annual Meeting by more than 25 days from the one-year anniversary of the 2022 Annual Meeting, then the written notice of a stockholder proposal that is not intended to be included in our proxy statement must be received, no earlier than the 120th day prior to our 2023 Annual Meeting and no later than the 10th day following the day on which public announcement of the date of the 2023 Annual Meeting is first made by the Company. The public announcement of an adjournment or postponement of the 2023 Annual Meeting does not commence a new time period (or extend any time period) for the giving of a stockholder’s notice as described in this Proxy Statement. You are advised to review our Bylaws, which contain additional requirements with respect to advance notice of stockholder proposals and director nominees.

Householding

We have adopted a procedure approved by the SEC called “householding.” Under this procedure, service providers that deliver our communications to stockholders may deliver a single copy of our Annual Report, Proxy Statement, or the Notice to multiple stockholders sharing the same address, unless one or more of these stockholders notifies us that they wish to continue receiving individual copies. Stockholders who participate in householding will continue to receive separate proxy cards. This householding procedure reduces our printing costs and postage fees.

We will deliver promptly upon written or oral request a separate copy of our Annual Report, Proxy Statement, or the Notice, as applicable, to a stockholder at a shared address to which a single copy of the

TABLE OF CONTENTS

documents was delivered. Please notify Continental Stock Transfer by phone at 917-262-2373 or by email at proxy@continentalstock.com to receive a separate copy of our Annual Report, Proxy Statement, or the Notice.

If you are eligible for householding, but you and other stockholders with whom you share an address currently receive multiple copies of our annual reports, proxy statements and/or notices, or if you hold stock in more than one account, and in either case you wish to receive only a single copy of our Annual Report, Proxy Statement, or the Notice for your household, please contact Continental Stock Transfer at the address or phone number provided above.

How to Obtain the Results of Voting at Annual Meeting

Preliminary voting results will be announced at the Annual Meeting. Final voting results will be published in a Current Report on Form 8-K filed with the SEC within four business days following the Annual Meeting. If final voting results are not available to us within four business days following the Annual Meeting, we will file a Current Report on Form 8-K to publish preliminary results and will file an additional Current Report on Form 8-K to publish the final voting results within four business days of such final voting results being made available to us.

Impact of the Company Qualifying as Emerging Growth Company

We are an “emerging growth company” under applicable federal securities laws and therefore are permitted to take advantage of certain reduced public company reporting requirements. As an emerging growth company, we provide in this Proxy Statement the scaled disclosure permitted under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), including the scaled compensation disclosures required of a “smaller reporting company,” as that term is defined in Rule 12b-2 promulgated under the Exchange Act. In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our named executive officers or the frequency with which such votes must be conducted.

Our Mailing Address

Our mailing address is 486 S. Pierce Avenue, Suite E, Louisville, CO 80027.

TABLE OF CONTENTS

PROPOSAL NO. 1 — ELECTION OF DIRECTORS

Directors

Our Board is divided into three classes, each serving staggered, three-year terms.

•

Our Class I directors are Erik Anderson, Douglas Campbell, Lesa Roe and Robert M. Tichio, and their current terms expire at this year’s Annual Meeting;

•

Our Class II directors are Steven H. Goldberg and Aleksandra Miziolek, and their current terms expire at the 2023 annual meeting of the stockholders; and

•

Our Class III directors are David B. Jansen, Rainer Feurer and John Stephens, and their current terms expire at the 2024 annual meeting of the stockholders.

On March 17, 2022, Mr. Tichio provided notice to the Board of his decision to not stand for re-election at the Annual Meeting. Mr. Tichio informed the Board that his decision was due to the extent of his commitments to Riverstone Holdings LLC (“Riverstone”) and service on the boards of several Riverstone portfolio investments. Mr. Tichio’s decision not to stand for re-election was not the result of any disagreement with the Company. In connection with Mr. Tichio’s decision not to stand for re-election, the Board, at the recommendation of the nominating and corporate governance committee, voted to reclassify Mr. Campbell as a Class I director and nominate him, along with Mr. Anderson and Ms. Roe, for re-election to the Board at the Annual Meeting. Also at the recommendation of the nominating and corporate governance committee, the Board voted to reduce the size of the Board to eight members immediately upon completion of the Annual Meeting, subject to the re-election of Messrs. Anderson and Campbell and Ms. Roe at the Annual Meeting.

As such, our stockholders will elect three Class I directors at the Annual Meeting. Each of the Class I directors is expected to hold office until the 2025 annual meeting of our stockholders, or until his or her respective successor shall be duly elected and qualified. Directors are elected by a plurality of the voting power of the shares present in person or represented by proxy at the 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.

Each nominee is recommended by the Board, at the recommendation of the nominating and corporate governance committee, and all nominees are current directors of the Company. Each nominee has consented to his or her nomination and has advised us that he or she intends to serve if elected. If, at the time of the Annual Meeting, one or more of the nominees becomes unable to serve: (i) shares represented by proxies will be voted for the remaining nominees and for any substitute nominee or nominees; or (ii) the Board of Directors may, in accordance with our Bylaws, reduce the size of the Board of Directors or may leave a vacancy until a nominee is identified.

The following is a brief biography and certain other information for each of our directors with terms expiring at the Annual Meeting who are also nominees for election as a director at the Annual Meeting and for each of the continuing directors.

He began his career in advanced technology development at the Space Vehicles Directorate of the Air Force Research Laboratory, Kirtland AFB, NM. Mr. Campbell earned his B.S. and M.S. in Civil Engineering with a Structural Mechanics emphasis from the University of New Mexico.

CORPORATE GOVERNANCE MATTERS

Classified Board of Directors

Our Second Amended and Restated Certificate of Incorporation provides that the Board is divided into three classes serving staggered three-year terms. Class I, Class II and Class III directors will serve until our annual meetings of stockholders in 2022, 2023 and 2024, respectively. Upon expiration of the term of a class of directors, directors in that class will be eligible to be elected for a new three-year term at the annual meeting of stockholders in the year in which their term expires. As a result of this classification of directors, it generally takes at least two annual meetings of stockholders for stockholders to effect a change in a majority of the members of the Board.

Meetings

Our Board did not hold any meetings in 2021 following the consummation of the Business Combination and the Legacy Solid Power Board held three meetings in 2021 before the Business Combination. There were no committee meetings held in 2021. Each of our directors attended at least 75% of the total number of meetings of the Legacy Solid Power Board held during the period in which he was a director.

Director Independence

Our Board, at the recommendation of the nominating and corporate governance committee, has affirmatively determined that each of the directors on the Board other than Messrs. Campbell, Feurer and Jansen qualify as independent directors, as defined under the rules of the Nasdaq Global Select Market, and the Board consists of a majority of “independent directors,” as defined under the rules of the SEC and the Nasdaq Global Select Market relating to director independence requirements. In addition, we are subject to the rules of the SEC and the Nasdaq Global Select Market relating to the membership, qualifications, and operations of the audit committee and the membership of the compensation committee, as discussed below. John Stephens is our lead independent director under the rules of the Nasdaq Global Select Market.

Family Relationships

There are no family relationships among any of our directors and executive officers.

Committees of the Board of Directors

Our Board has three standing committees: an audit committee, a compensation committee, and a nominating and corporate governance committee. The function and authority of these committees are described below:

Audit Committee

Our audit committee currently consists of Erik Anderson, Steven H. Goldberg, Lesa Roe and John Stephens. The Board, at the recommendation of the nominating and corporate governance committee, has determined that each of the members of the audit committee satisfies the heightened independence requirements of the Nasdaq Global Select Market and Rule 10A-3 under the Exchange Act and is able to read and understand fundamental financial statements in accordance with the Nasdaq Global Select Market audit committee requirements. In arriving at this determination, the nominating and corporate governance committee and Board examined each audit committee member’s scope of experience and the nature of their prior and/or current employment.

John Stephens serves as the chair of the audit committee. The Board, at the recommendation of the nominating and corporate governance committee, determined that Mr. Stephens qualifies as an audit committee financial expert within the meaning of SEC regulations and meets the financial sophistication requirements of the rules of the Nasdaq Global Select Market. In making this determination, the nominating and corporate governance committee and Board considered formal education and previous experience in financial roles.

However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the compensation committee will consider the independence of each such adviser, including the factors required by the Nasdaq Global Select Market and the SEC.

TABLE OF CONTENTS

In May 2021, the Legacy Solid Power Board retained Compensia, Inc. (“Compensia”) as its independent compensation consultant. The compensation committee retained Compensia following the business combination to advise the compensation committee with respect to director and officer compensation matters.

Tichio serves as the chair of our nominating and corporate governance committee.

Board Leadership Structure

We combine the positions of President and Chairman of the Board. We believe that the President, as a Company executive, is in the best position to fulfill the Chairman’s responsibilities, including those related to identifying emerging issues facing the Company and communicating essential information to the Board about the Company’s performance and strategies. We believe his in-depth knowledge of the Company and his extensive executive and management experience makes him uniquely well positioned to lead the Board in developing and monitoring the strategic direction of the Company.

In addition, John Stephens serves as our lead independent director. As the lead independent director, Mr. Stephens is responsible for, among other things, calling separate meetings of the independent directors, determining the agenda and serving as chairperson of meetings of independent directors, reporting to our Chief Executive Officer and the Chairman of the Board regarding feedback from executive sessions, serving as spokesperson for the Company as requested, helping to set the agenda for meetings of the Board and performing such other responsibilities that may be designated by a majority of the independent directors from time to time.

Board’s Role in Risk Oversight

One of the key functions of the Board is informed oversight of our risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through various standing committees of the Board that address risks inherent in their respective areas of oversight. In particular, our audit committee has the responsibility to oversee and discuss our enterprise risk management, including major financial risk exposures, and the steps our management will take to monitor and oversee such exposures, such as guidelines and policies to govern the processes by which risk assessment and management is undertaken. In addition to enterprise risk management, the audit committee also monitors compliance with legal and regulatory requirements and ethical programs, including our global anti-bribery and anti-corruption policy, and also reviews and discusses with management our cybersecurity risk exposures and the steps taken to monitor or mitigate such exposures. Our compensation committee assesses and monitors whether our compensation plans, policies and programs comply with applicable legal and regulatory requirements. Our nominating and corporate governance committee is responsible for monitoring compliance with our Code of Conduct which, among other things, promotes honest and ethical conduct and the appropriate handling of actual or apparent conflicts of interest. The Board or applicable committee also has authority to engage external advisors to the extent necessary or appropriate.

Other Information about the Board of Directors

TABLE OF CONTENTS

fiscal year, on the compensation committee or board of directors of any other entity that has one or more executive officers that serve as a member of the Board or compensation committee.

Code of Business Conduct

The Board adopted a code of business conduct and ethics (the “Code of Conduct”), applicable to all of our employees, executive officers and directors. The Code of Conduct is available on our website. The nominating and corporate governance committee of the Board is responsible for developing, reviewing, and monitoring compliance with the Code of Conduct, other than matters related to accounting or auditing matters, which are handled by our audit committee. Any waivers of the Code of Conduct for employees, executive officers or directors must be approved by the Board. We expect that any amendments to the Code of Conduct, or any waivers of its requirements, will be disclosed on our website.

Corporate Governance Guidelines

The Board adopted corporate governance guidelines that serve as a framework within which the Board and its committees operate. These guidelines cover a number of areas including director responsibilities, Board agenda, roles of the chair of the Board, principal executive officer and lead independent director, meetings of independent directors, committee responsibilities and assignments, Board member access to management and independent advisors, director communications with third parties, director orientation and continuing education, evaluation of senior management and management succession planning. A copy of our corporate governance guidelines is posted on our website.

Annual Meeting Attendance

Each of our directors is strongly encouraged to attend our annual meetings of stockholders. We expect that all of our directors will attend the 2022 Annual Meeting.

Director Nominations

Our nominating and corporate governance committee will recommend to the Board candidates for nomination for election at the annual meeting of the stockholders. The Board will also consider director candidates recommended for nomination by our stockholders during such times as they are seeking proposed nominees to stand for election at the next annual meeting of stockholders (or, if applicable, a special meeting of stockholders). Stockholders that wish to nominate a director for election to the Board should follow the procedures set forth in our Bylaws.

We do not intend to formally establish any specific, minimum qualifications that must be met or skills that are necessary for directors to possess. In general, in identifying and evaluating nominees for director, the Board considers character, professional ethics and integrity, judgment, business acumen, proven achievement and competence in one’s field, the ability to exercise sound business judgment, tenure on the Board and skills that are complementary to the Board, an understanding of our business, an understanding of the responsibilities that are required of a member of the Board, other time commitments, diversity with respect to professional background, education, race, ethnicity, gender, age and geography, as well as other individual qualities, attributes that contribute to the total mix of viewpoints and experience represented on the Board and the ability to represent the best interests of our stockholders.

EXECUTIVE COMPENSATION

To achieve our goals, we have designed, and intend to modify as necessary, our compensation and benefits program to attract, retain, incentivize and reward talented and qualified executives who share our philosophy and desire to work towards achieving our goals.

We believe our compensation program should promote the success of our company and align executive incentives with the long-term interests of our stockholders. Our compensation program for 2021 executive compensation reflected our startup origins in that they consisted primarily of salary, bonus and stock option awards. We intend to continue to evaluate our philosophy and compensation programs as circumstances require. In May 2021, Legacy Solid Power engaged Compensia, an independent compensation consultant, to assess the competitiveness of our executive and director compensation programs.

We are considered an emerging growth company for purposes of the SEC’s executive compensation disclosure rules. In accordance with such rules, this section provides an overview of our executive compensation programs, including a narrative description of the material factors necessary to understand the information disclosed in the summary compensation table below. As an emerging growth company, our reporting obligations extend only to the individuals serving as our chief executive officer and our two other most highly compensated executive officers for 2021, whom we refer to as our “named executive officers” or our “NEOs”.

The option expires on October 19, 2031.

Executive Change in Control and Severance Plan

Each outstanding option to purchase shares of our Common Stock held by our named executive officers and granted prior to August 2021 is subject to vesting acceleration under the 2014 Plan Vesting Acceleration provisions below.

In August 2021, the Legacy Solid Power Board adopted an Executive Change in Control and Severance Plan, or the Executive Severance Plan, pursuant to which our named executive officers and certain other key employees are eligible to receive severance benefits, as specified in and subject to the employee signing a participation agreement under our Executive Severance Plan. This Executive Severance Plan was developed with input from Compensia, regarding severance practices at comparable companies. It is designed to attract, retain and reward senior level employees. The Executive Severance Plan will be in lieu of any other severance payments and benefits to which such key employee was entitled prior to signing the participation agreement, other than the 2014 Plan Vesting Acceleration provisions, which will continue to apply.

Each of our named executive officers (each, a “participant”) has entered into a participation agreement under our Executive Severance Plan providing for the rights to the applicable payments and benefits described below.

In the event of an “involuntary termination” of the employment of a participant (i) by us for a reason other than “cause,” or the participant’s death or “disability,” or (ii) by him for “good reason” (as such terms are defined in our Executive Severance Plan), in either case, that occurs outside the change in control period (as described below), then the participant will be entitled to the following payments and benefits:

•

a lump sum payment equal to six months of the participant’s annual base salary as in effect immediately prior to their involuntary termination of employment, or, in the case of Mr. Campbell, 12 months; and

TABLE OF CONTENTS

•

reimbursement for premium cost for continued health coverage under the Consolidated Omnibus Reconciliation Act of 1985 as amended, or COBRA, or a taxable lump sum payment equal to the premium cost of continued health coverage under COBRA, for a period of six months, or, in the case of Mr. Campbell, 12 months.

In the event of an “involuntary termination” of the employment of a participant (i) by us for a reason other than “cause,” or the participant’s death or “disability” or, (ii) by him for “good reason,” in either case, within a period beginning three months prior to and ending 12 months following a “change in control” (as defined in our Executive Severance Plan) (such period, the “change in control period”), then the participant will be entitled to the following payments and benefits:

•

a lump sum payment equal to 12 months of the participant’s annual base salary as in effect immediately prior to their involuntary termination of employment, or, in the case of Mr. Campbell, 18 months;

•

a lump sum payment equal to such participant’s annual target bonus in effect for the year of termination, or, in the case of Mr. Campbell, 150% of annual target bonus in effect for the year of termination;

•

reimbursement for premium cost for continued health coverage under COBRA or a taxable lump sum payments equal to the premium cost of continued health coverage under COBRA for a period of 12 months, or, in the case of Mr. Campbell, 18 months; and

•

100% accelerated vesting of all outstanding equity awards granted on or after August 4, 2021, and, with respect to such equity awards with performance-based vesting, all performance goals or other vesting criteria will be deemed achieved at 100% of target levels for the relevant performance period(s).

The receipt of the payments and benefits provided for under the Executive Severance Plan described above is conditioned on the participant 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 participant’s involuntary termination of employment, as well as compliance with certain non-disparagement provisions and continued compliance with the invention assignment and confidentiality agreement applicable to the participant.

In addition, if any of the payments or benefits provided for under the Executive Severance Plan or otherwise payable to a participant 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 participant 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 them. The Executive Severance Plan does not require us to provide any tax gross-up payments to the participants.

2021 Named Executive Officer Compensation

In August 2021, the Legacy Solid Power Board, in consultation with Compensia, approved market-based adjustments to the base salary and target annual bonus opportunities for our named executive officers and other key employees.

In August 2021, the Legacy Solid Power Board also approved option grants to Mr. Campbell and Mr. Jansen covering 150,000 shares and 400,000 shares, respectively, of Legacy Solid Power Common Stock, at an exercise price per share of Legacy Solid Power Common Stock of $15.96. In October 2021, the Legacy Solid Power Board approved an option grant to Mr. Jacobs covering 325,000 shares of Legacy Solid Power Common Stock, at an exercise price per share of Legacy Solid Power Common Stock of $18.82. These grants were made to provide them additional incentives to remain with us and to promote further alignment between their interests and those of our stockholders. In determining the size of these grants, the Legacy Solid Power Board, in consultation with Compensia, considered several factors, including the percentage ownership in Legacy Solid Power held by each named executive officer and the amount his ownership interests were unvested as of the date of grant, the estimated value of his company ownership interests, market data for similarly situated executives at comparable companies, the named executive officer’s past and expected future contributions.

TABLE OF CONTENTS

The grants are subject to the terms and conditions of the 2014 Plan and the applicable form of option agreement thereunder, and vest as to 1/4th of these shares after one year after the grant date with the balance of the shares vesting in a series of 36 successive equal monthly installments measured from the first anniversary of the grant date, subject to the named executive officer’s continued service with us, and further subject to vesting acceleration under the 2014 Plan Non-Assumption Provision and under certain circumstances as described under “— Potential Payments upon Termination or Change in Control.”

Pursuant to the Business Combination, on the Closing Date, each Legacy Solid Power option was converted into an option to purchase a number of shares of Common Stock of the Company, equal to the product (rounded down to the nearest whole number) of (x) the number of shares of Legacy Solid Power Common Stock subject to such Legacy Solid Power option immediately prior to the Closing Date and (y) an exchange ratio equal to approximately 3.182 (the “Exchange Ratio”), at an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per share of such Legacy Solid Power option immediately prior to the Closing Date divided by (B) the Exchange Ratio.

(2)

Mr. Campbell exercised this stock option and acquired 5,091,169 shares of Common Stock on January 12, 2022.

(3)

The shares of Common Stock subject to these stock options vest and become exercisable under the following schedule: 25% of the shares subject to the stock option vest on August 3, 2022 and 1/36 of the remaining shares subject to the stock option will vest monthly thereafter.

(4)

The shares of Common Stock subject to these stock options vest and become exercisable under the following schedule: 25% of the shares subject to the stock option vest on October 18, 2022 and 1/36 of the remaining shares subject to the stock option will vest monthly thereafter.

401(k) Plan

We maintain a 401(k) retirement savings plan, for the benefit of our employees, including our named executive officers, who satisfy certain eligibility requirements. 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 are 100% vested when contributed. 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. Any nonelective employer contribution allocated to a participant will be scheduled to vest as to 25% of such contribution when the participant completes two years of service and as to 25% of such contribution when the participant completes each additional year of service. The 401(k) plan is intended to qualify under Sections 401(a) and 501(a) of the Code.

TABLE OF CONTENTS

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.

Treatment of Legacy Solid Power Options in the Merger

As of the Closing Date and by virtue of the merger, each Legacy Solid Power Option that was outstanding and unexercised as of immediately prior to the Closing Date was converted into an option to acquire a number of shares of our Common Stock equal to the product of (x) the number of shares of Legacy Solid Power Common Stock subject to the applicable Legacy Solid Power Option and (y) the Exchange Ratio, and was subject to the same terms and conditions as were applicable to such Legacy Solid Power Option (each an “Assumed Solid Power Option”). The exercise price per share of each Assumed Solid Power Option was equal to the quotient obtained by dividing (x) the exercise price per share applicable to such Legacy Solid Power Option by (y) the Exchange Ratio.

DIRECTOR COMPENSATION

Outside Director Compensation Policy

On December 8, 2021, the Board approved the Outside Director Compensation Policy for non-employee directors (the “Outside Director Compensation Policy”), which is designed to attract, retain and reward outside directors. Under the 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 expenses.

Maximum Annual Compensation Limit

Our Outside Director Compensation Policy 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 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 GAAP as then in effect. Any cash compensation or equity awards granted under the 2021 Equity Incentive Plan (the “2021 Plan”) to an outside director for his or her services as an employee, or for his or her services as a consultant (other than as an outside director) or prior to the Closing Date, 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

Outside directors are entitled to receive the following compensation for their service under our Outside Director Compensation Policy:

•

$35,000 per year for service as a board member;

•

$25,000 per year for service as a lead independent director;

•

$35,000 per year for service as chair of the audit committee;

•

$10,000 per year for service as a member of the audit committee;

•

$15,000 per year for service as chair of the compensation committee;

•

$7,500 per year for service as a member of the compensation committee;

•

$10,000 per year for service as chair of the nominating and corporate governance committee; and

•

$5,000 per year for service as a member of the nominating and corporate governance committee.

Each outside director who serves as the chair of a committee will receive only the annual cash fee as the chair of the committee, and not the additional annual cash fee as a member of the committee. All cash payments to outside directors are paid quarterly in arrears on a pro-rated basis.

TABLE OF CONTENTS

Equity Compensation

Immediately prior to a Change in Control (as defined in the 2021 Plan), each outside director’s outstanding awards will fully vest, provided that the outside director continues to be an outside director through the date of the change in control.

Initial Awards

Each individual who first becomes an outside director following the effective date of the Outside Director Compensation Policy will be granted an award of Restricted Stock Units (an “Initial Award”) covering a number of shares of Common Stock, with such Award having a grant date fair value (determined in accordance with GAAP) (the “Grant Value”) equal to $165,000, rounded to the nearest whole share of Common Stock.

Each Initial Award will vest as to 1/12th of the Initial Award beginning on the first Company Quarterly Vesting Date (as defined below) following the outside director’s service and as to 1/12th of the Initial Award on each Company Quarterly Vesting Date thereafter, subject to the outside director continuing to be a service provider through the applicable vesting date. “Company Quarterly Vesting Date” means February 15, May 15, August 15, or November 15 of each year.

Annual Award

On the date of each annual meeting of stockholders following the effective date of the Outside Director Compensation Policy, each outside director will be automatically granted an award of Restricted Stock Units (an “Annual Award”) covering a number of shares of Common Stock, with such award having a grant value of $125,000, rounded to the nearest whole share of Common Stock.

Narrative Discussion Regarding 2021 Director Compensation

Prior to December 8, 2021, our policy was to reimburse outside directors for reasonable and necessary out-of-pocket expenses incurred in connection with attending Board and committee meetings. We also paid

TABLE OF CONTENTS

nominal cash fees for performing other services in their capacities as outside directors and occasionally granted stock options to our outside directors. In connection with joining the Legacy Solid Power Board, Mr. Stephens received an option to purchase 120,000 shares of Legacy Solid Power Common Stock at an exercise price of $18.82 per share, which converted into an option to purchase 381,837 shares of Solid Power Common Stock at an exercise price of $5.92 per share on the Closing Date (the “Stephens Option”). The Stephens Option vests equally over three years beginning with first anniversary of the grant. The Legacy Solid Power Board granted the Stephens Option to compensate Mr. Stephens for joining the Legacy Solid Power Board in advance of, and to assist in consummating, the closing of the Business Combination and for his guidance and support of our subsequent transition to being a public company.

Hedging Policy

The Board believes that it is undesirable for our directors, officers and employees to engage in hedging or speculative transactions that may put the personal gain of the insider in conflict with the best interests of the Company and our securityholders or otherwise give the appearance of impropriety. Therefore, our directors, officers, and employees, whether or not in possession of material non-public information, are generally prohibited from: (i) selling our securities “short” (i.e., selling stock that is not owned and borrowing the shares to make delivery), (ii) transacting in put options, call options or other derivative securities, on an exchange or in any other organized market, (iii) engaging in hedging or monetization transactions, such as the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds, and (iv) certain other transactions set forth in our insider trading policy.

TABLE OF CONTENTS

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table shows information, as of March 15, 2022, concerning the beneficial ownership of our common stock by: (i) each person we know to be the beneficial owner of more than 5% of our common stock; (ii) each of our current directors; (iii) each of our NEOs shown in our Summary Compensation Table; and (iv) all current directors and executive officers as a group.

As of March 15, 2022, there were 172,649,157 shares of our common stock issued and outstanding. Beneficial ownership is determined according to the rules of the SEC and generally means that a person has beneficial ownership of a security if such person possesses sole or shared voting or investment power of that security, including options and warrants that are currently exercisable or exercisable within 60 days of March 15, 2022. Shares of our common stock issuable pursuant to stock options are deemed outstanding for computing the percentage of the person holding such options and the percentage of any group of which the person is a member but are not deemed outstanding for computing the percentage of any other person. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the persons named in the table below have sole voting and investment power with respect to all shares of common stock shown that they beneficially own, subject to community property laws where applicable.

Unless otherwise indicated, the address for each director and executive officer listed is: c/o Solid Power, Inc., 486 S. Pierce Avenue, Suite E, Louisville, CO 80027.

Founder Shares

In February 2021, the Sponsor purchased an aggregate of 10,062,500 shares of DCRC Class B Common Stock in exchange for the payment of $25,000 of expenses on DCRC’s behalf. In March 2021, the Sponsor forfeited 400,000 shares of DCRC Class B Common Stock, and an aggregate of 400,000 shares of DCRC Class B Common Stock were issued to DCRC’s independent director nominees at their original purchase price.

In May 2021, the Sponsor forfeited 1,312,500 shares of DCRC Class B Common Stock in connection with the expiration of the underwriters’ over-allotment option for the initial public offering, resulting in the Sponsor and DCRC’s independent directors holding an aggregate of 8,750,000 shares of DCRC Class B Common Stock (the “Founder Shares”). On October 25, 2021, certain of the initial stockholders elected to convert an aggregate of 8,710,000 of the Founder Shares into shares of DCRC Class A Common Stock. At Closing, the remaining 40,000 Founder Shares then outstanding automatically converted into shares of our Common Stock.

Private Placement Warrants

The Sponsor and DCRC’s independent directors hold an aggregate of 7,666,667 Private Placement Warrants, 6,666,667 of which were purchased for a purchase price of $1.50 per Warrant in a private placement that occurred simultaneously with the closing of the initial public offering and 1,000,000 of which were issued in exchange for the forgiveness of $1.5 million of working loans incurred by DCRC to finance transaction costs in connection with the Business Combination.

Each Private Placement Warrant entitles the holder to purchase one share of our Common Stock at $11.50 per share. The Private Placement Warrants (including the Common Stock issuable upon exercise thereof) could not, subject to certain limited exceptions, be transferred, assigned or sold by the holder until January 7, 2022.

space, utilities and secretarial and administrative support. Upon completion of the Business Combination, DCRC ceased paying these monthly fees.

The Sponsor, officers and directors, or any of their respective affiliates, was reimbursed for any out-of-pocket expenses incurred in connection with activities on DCRC’s behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. DCRC’s audit committee reviewed on a quarterly basis all payments that were made to the Sponsor, officers, directors or DCRC’s or their affiliates and determined which expenses and the amount of expenses that were reimbursed. There was no cap or ceiling on the reimbursement of out-of-pocket expenses incurred by such persons in connection with activities on DCRC’s behalf.

Related Party Loans and Advances

DCRC’s liquidity needs up to the initial public offering were satisfied through receipt of a $25,000 capital contribution from the Sponsor in exchange for the issuance of Founder Shares to the Sponsor. Subsequent to the consummation of the initial public offering, DCRC’s liquidity needs were satisfied through the net proceeds of approximately $1.1 million from the private placement of 6,666,667 Private Placement Warrants held outside of the Trust Account.

In addition, in order to finance transaction costs in connection with the Business Combination, the Sponsor or an affiliate of the Sponsor or certain of DCRC’s officers and directors were permitted, but were not obligated, to loan DCRC funds as may have been required. Upon the closing of the Business Combination, DCRC repaid such loaned amounts other than $1.5 million, which was converted into 1,000,000 Private Placement Warrants.

Registration Rights

The Sponsor and directors of the Company prior to the Business Combination were entitled to certain registration rights pursuant to a registration rights agreement entered into in connection with the Company’s initial public offering. Such agreement was terminated and replaced by the Registration Rights Agreement in connection with the Business Combination.

Sponsor Letter

In connection with the execution of a business combination agreement (the “Business Combination Agreement”), on June 15, 2021, the Sponsor and certain directors of DCRC entered into the Sponsor Letter, pursuant to which, among other things, the Sponsor and such directors agreed to (i) waive the anti-dilution rights set forth in the DCRC Charter with respect to the Founder Shares held by them, (ii) comply with the lock-up provisions in the Letter Agreement, dated March 23, 2021, by and among DCRC, the Sponsor and DCRC’s directors and officers and (iii) vote all the shares of DCRC Class A Common Stock and Founder Shares held by them in favor of the adoption and approval of the Business Combination Agreement and the Business Combination.

Related Person Transaction Policy

The Board has adopted a written related person transaction policy that sets forth the following policies and procedures for the review and approval or ratification of related person transactions. For purposes of this policy, a “Related Person Transaction” is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which Solid Power or any of its subsidiaries was, is or will be a participant, the amount of which involved exceeds $120,000, and in which any related person had, has or will have a direct or indirect material interest.

Transactions involving compensation for services provided to us as an employee, consultant or director will not be considered related person transactions under this policy. A related person is any executive officer, director, nominee to become a director or a holder of more than 5% of any class of our voting securities (including Common Stock), including any of their immediate family members and affiliates, including entities owned or controlled by such persons.

TABLE OF CONTENTS

Under the policy, the related person in question or, in the case of transactions with a holder of more than 5% of any class of our voting securities, an officer with knowledge of a proposed transaction, must present information regarding the proposed related person transaction to the audit committee of the Board (or, where review by the audit committee would be inappropriate, to another independent body of the Board) for review. To identify related person transactions in advance, we will rely on information supplied by our executive officers, directors and certain significant stockholders. In considering related person transactions, the audit committee will consider the relevant available facts and circumstances, which may include, but are not limited to:

•

any person who is, or at any time during the applicable period was, one of our executive officers or a member of the Board;

•

the risks, costs, and benefits to us;

•

the impact on a director’s independence in the event the related person is a director, immediate family member of a director or an entity with which a director is affiliated;

•

the terms of the transaction;

•

the availability of other sources for comparable services or products; and

•

the terms available to or from, as the case may be, unrelated third parties.

Our audit committee will approve only those transactions that it determines are fair to us and in our best interests. All of the transactions described above were entered into prior to the adoption of such policy.

PROPOSAL NO. 2 — RATIFICATION OF INDEPENDENT REGISTERED PUBLIC
ACCOUNTING FIRM

The audit committee of our Board of Directors has selected Ernst & Young, LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022 and the Board has directed that management submit the selection of our independent registered public accounting firm for ratification by the stockholders at the annual meeting. Ernst & Young, LLP has been engaged by us since December 8, 2021. Representatives of Ernst & Young, LLP are expected to be present at the annual meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our Bylaws nor other governing documents or law require stockholder ratification of the selection of Ernst & Young, LLP as our independent registered public accounting firm. However, the Board is submitting the selection of Ernst & Young, LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the audit committee will reconsider whether or not to retain Ernst & Young, LLP. Even if the selection is ratified, the audit committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if the audit committee determines that such a change would be in our and our stockholders’ best interests.

Change in Auditor

On December 8, 2021, the audit committee through a written consent approved the engagement of Ernst & Young, LLP as the Company’s independent registered public accounting firm to audit the Company’s consolidated financial statements for the year ended December 31, 2021. Ernst & Young, LLP served as independent registered public accounting firm of Legacy Solid Power prior to the Business Combination. Accordingly, as previously disclosed, WithumSmith+Brown, PC (“Withum”), the independent registered public accounting firm of DCRC prior to the Business Combination, was informed on December 8, 2021 that it would be replaced by Ernst & Young, LLP.

The report of Withum on DCRC’s financial statements as of June 30, 2021 and for the period from January 29, 2021 (DCRC’s inception) through June 30, 2021, did not contain an adverse opinion or a disclaimer of opinion, and was not qualified or modified as to audit scope or accounting principles.

During the period from January 29, 2021 (DCRC’s inception) to June 30, 2021 and the subsequent interim period through December 8, 2021, there were no “disagreements” (as such term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) with Withum on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of Withum, would have caused Withum to make reference thereto in its report on DCRC’s pre-merger financial statements as of June 30, 2021 and for the period from January 29, 2021 (DCRC’s inception) to June 30, 2021. During the period from January 29, 2021 (DCRC’s inception) to June 30, 2021 and the subsequent interim period through December 8, 2021, there were no “reportable events” (as such term is defined in Item 304(a)(1)(v) of Regulation S-K.).

We provided Withum with a copy of the foregoing disclosures when they were originally disclosed in the Company’s Current Report on Form 8-K filed with the SEC on December 13, 2021, at which time Withum furnished a letter addressed to the SEC stating that it agreed with the statements made therein, a copy of which is incorporated as Exhibit 16.2 to the Company’s Current Report on Form 8-K filed with the SEC on December 13, 2021.

Vote Required

The affirmative vote of the holders of a majority of the votes cast either virtually during the annual meeting or represented by proxy at the annual meeting will be required to ratify the selection of Ernst & Young, LLP for our fiscal year ending December 31, 2022. Abstentions will not be counted as votes cast on this proposal. No broker non-votes are expected to exist in connection with this proposal.

Pre-Approval Policies and Procedures

The audit committee’s policy is to pre-approve all audit and permissible non-audit services rendered by our independent registered public accounting firm. The audit committee can pre-approve specified services in defined categories of audit services, audit-related services and tax services up to specified amounts, as part of the audit committee’s approval of the scope of the engagement of our independent registered public accounting firm or on an individual case-by-case basis before our independent registered public accounting firm is engaged to provide a service. The audit committee has determined that the rendering of tax-related services by our independent registered public accounting firm is compatible with maintaining the principal accountant’s independence for audit purposes. Our independent registered public accounting firm has not been engaged to perform any non-audit services other than tax-related services.

THE BOARD OF DIRECTORS AND THE AUDIT COMMITTEE RECOMMEND A VOTE
“FOR” PROPOSAL 2.

TABLE OF CONTENTS

REPORT OF THE AUDIT COMMITTEE

The audit committee operates pursuant to a written charter, which complies with the corporate governance standards of The Nasdaq Global Select Market. A copy of the current charter is available on our website. This report reviews the actions taken by the audit committee with regard to our financial reporting process for the fiscal year 2021 and the audited consolidated financial statements.

The audit committee is composed solely of independent directors. None of the audit committee members is or has been an officer or employee of the Company or any of our subsidiaries or has any current business or any family relationship with the Company or any of our subsidiaries or affiliates.

Our management has the primary responsibility for the financial statements and reporting process, including the systems of internal controls. The independent auditors are responsible for performing an independent audit of our consolidated financial statements in accordance with auditing standards generally accepted in the United States and issuing a report thereon. The audit committee’s responsibility is to monitor and oversee these processes and to select annually the accountants to serve as our independent auditors for the coming year.

In fulfilling its oversight responsibilities, the audit committee reviewed and discussed with management the audited consolidated financial statements in our Annual Report for the year ended December 31, 2021, including a discussion of the quality, rather than just the acceptability, of the accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements.

The audit committee also discussed with the independent auditors, who are responsible for expressing an opinion on the conformity of those audited consolidated financial statements with accounting principles generally accepted in the United States, their judgments as to the quality, rather than just the acceptability, of our accounting principles and such other matters as are required to be discussed with the audit committee under the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The audit committee also reviewed and discussed with the independent auditors the critical audit matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the consolidated financial statements, and (2) involved the auditor’s especially challenging, subjective or complex judgments. In addition, the audit committee discussed with the auditors their independence from management and the Company, including the matters in the written disclosures and the letter required by the PCAOB regarding the independent auditors’communications with the audit committee regarding independence. The audit committee also considered whether the provision of services during the fiscal year ended December 31, 2021 by the auditors that were unrelated to their audit of the consolidated financial statements referred to above and to their reviews of our interim consolidated financial statements during the fiscal year is compatible with maintaining their independence.

Additionally, the audit committee discussed with the independent auditors the overall scope and plan for their audit. The audit committee met with the independent auditors, with and without management present, to discuss the results of their examination, their evaluation of our internal controls and the overall quality of our financial reporting.

In reliance on the reviews and discussions referred to above, the audit committee recommended to the Board that the audited consolidated financial statements be included in our Annual Report for the year ended December 31, 2021 for filing with the SEC.

*The material in this report is not “soliciting material,” is not deemed “filed” with the SEC and is not to be incorporated by reference in any filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.
