PROXY STATEMENT

FOR THE 2025 ANNUAL MEETING OF STOCKHOLDERS

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND VOTING

What Is the Purpose of These Proxy Materials?

Why Did I Receive a Notice of Internet Availability?

Pursuant to SEC rules, we are furnishing the proxy materials to our stockholders primarily via the Internet instead of mailing printed copies. This process allows us to expedite our stockholders’ receipt of proxy materials, lower the costs of printing and mailing the proxy materials, and reduce the environmental impact of our Annual Meeting. If you received a Notice of Internet Availability of Proxy Materials (the “Notice”), you will not receive a printed copy of the proxy materials unless you request one. The Notice provides instructions on how to access the proxy materials for the Annual Meeting via the Internet, how to request a printed set of proxy materials, and how to vote your shares.

Why Are We Holding a Virtual Annual Meeting?

We have adopted a virtual meeting format for the Annual Meeting to provide a consistent experience to all stockholders regardless of geographic location. We believe this expands stockholder access, improves communications, and lowers our costs, while reducing the environmental impact of the meeting. In structuring our virtual Annual Meeting, our goal is to enhance rather than constrain stockholder participation in the meeting, and we have designed the meeting to provide stockholders with the same rights and opportunities to participate as they would have at an in-person meeting.

Who Can Vote?

What Is the Difference between Holding Shares of Common Stock as a Registered Stockholder and as a Beneficial Owner?

Registered Stockholder: Shares Registered in Your Name

If your shares of common stock are registered directly in your name with our transfer agent, Computershare Trust Company, N.A., you are considered to be, with respect to those shares of common stock, the registered stockholder, and these proxy materials are being sent directly to you by us.

1

Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary, or Custodian

If your shares of common stock are held by a broker, fiduciary, or custodian, you are considered the beneficial owner of shares of common stock held in “street name,” and these proxy materials are being forwarded to you from that broker, fiduciary, or custodian.

How Can I Participate in the Virtual Annual Meeting?

Only stockholders of record and beneficial owners of shares of our common stock as of the close of business on April 11, 2025, the Record Date, may attend and participate in the virtual Annual Meeting, including to vote and ask questions. Because the Annual Meeting is solely virtual, you will not be able to attend the Annual Meeting physically in person.

If you are the beneficial owner of shares held of record (i.e. in “street name”) by a broker, bank, or other nominee, you will receive voting instructions from your broker, bank, or other nominee. If your voting instruction form or Notice indicates that you may vote those shares through www.proxyvote.com, then you may access, participate in and vote at the Annual Meeting with the 16-digit access code indicated on that voting instruction form or Notice. Otherwise, stockholders who hold their shares in street name should contact their bank, broker or other nominee (preferably at least five days before the Annual Meeting) and obtain a “legal proxy” in order to be able to attend, participate in or vote at the Annual Meeting.

If you are the stockholder of record, you may vote and ask questions at the meeting by logging on to the meeting website at www.virtualshareholdermeeting.com/STEM2025, enter the control number found on your proxy card or Notice, and follow the instructions on the website.

We will endeavor to answer as many stockholder-submitted questions as time permits that comply with the Annual Meeting rules of conduct. We reserve the right to edit profanity or other inappropriate language and to exclude questions regarding topics that are not pertinent to meeting matters or Company business. If we receive substantially similar questions, we may group such questions together and provide a single response to avoid repetition.

The meeting webcast will begin promptly at 9:00 a.m. Pacific Time. Online check-in will begin approximately 15 minutes before then. We encourage you to allow ample time for check-in procedures. If you experience technical difficulties during the check-in process or during the meeting, please call the number listed on the meeting website for technical support. Additional information regarding the rules and procedures for participating in the Annual Meeting will be set forth in our meeting rules of conduct, which stockholders can view during the meeting at the meeting website.

What Am I Voting on?

The proposals to be voted on at the Annual Meeting are as follows:

2

How Does the Board Recommend That I Vote?

The Board recommends that you vote your shares “FOR” each director nominee in Proposal 1 and “FOR” Proposals 2 through 7.

What If Another Matter Is Properly Brought before the Annual Meeting?

As of the date of filing this Proxy Statement, the Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, it is the intention of the persons named as proxies in the proxy card to vote on such matters in accordance with their best judgment.

How Many Votes Do I Have?

Each share of common stock is entitled to one vote on each proposal to be voted on at the Annual Meeting.

What Does It Mean If I Receive More Than One Set of Proxy Materials?

If you receive more than one set of proxy materials, your shares may be registered in more than one name or held in different accounts. Please cast your vote with respect to each set of proxy materials that you receive to ensure that all of your shares are voted.

How Do I Vote?

Registered Stockholder: Shares Registered in Your Name

If you are the registered stockholder, you may vote your shares online during the virtual Annual Meeting (see “How Can I Participate in the Virtual Annual Meeting?” above) or by proxy in advance of the Annual Meeting by Internet at www.proxyvote.com or, if you requested paper copies of the proxy materials, by completing and mailing a proxy card or by telephone at 1-800-690-6903. Even if you plan to attend the Annual Meeting, we recommend that you also submit your vote as early as possible in advance so that your vote will be counted if you later decide not to, or are unable to, virtually attend the Annual Meeting.

Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary, or Custodian

If you are the beneficial owner, you will receive voting instructions from your broker, bank, or other nominee. You must follow the voting instructions provided by your broker, bank, or other nominee in order to instruct your broker, bank, or other nominee how to vote your shares. The availability of Internet and telephone voting options will depend on the voting process of your broker, bank, or other nominee. You may not vote your shares live at the Annual Meeting unless you obtain a legal proxy from your broker, bank, or other nominee.

3

What Happens If I Do Not Vote?

Registered Stockholder: Shares Registered in Your Name

If you are the registered stockholder and do not vote in one of the ways described above, your shares will not be voted at the Annual Meeting and will not be counted toward the quorum requirement.

Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary, or Custodian

If you are the beneficial owner and do not direct your broker, fiduciary, or custodian how to vote your shares, your broker, fiduciary, or custodian will only be able to vote your shares with respect to proposals considered to be “routine.” Your broker, fiduciary, or custodian is not entitled to vote your shares with respect to “non-routine” proposals, which we refer to as a “broker non-vote.” Whether a proposal is considered routine or non-routine is subject to stock exchange rules and final determination by the stock exchange. Even with respect to routine matters, some brokers are choosing not to exercise discretionary voting authority. As a result, we urge you to direct your broker, fiduciary, or custodian how to vote your shares on all proposals to ensure that your vote is counted.

What If I Sign and Return a Proxy Card or Otherwise Vote but Do Not Indicate Specific Choices?

Registered Stockholder: Shares Registered in Your Name

The shares represented by each signed and returned proxy will be voted at the Annual Meeting by the persons named as proxies in the proxy card in accordance with the instructions indicated on the proxy card. However, if you are the registered stockholder and sign and return your proxy card without giving specific instructions, the persons named as proxies in the proxy card will vote your shares in accordance with the recommendations of the Board. Your shares will be counted toward the quorum requirement.

Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary, or Custodian

If you are the beneficial owner and sign and return your voting instruction form without giving specific instructions, your broker, fiduciary, or custodian will only be able to vote your shares with respect to proposals considered to be “routine.” Your broker, fiduciary, or custodian is not entitled to vote your shares with respect to “non-routine” proposals, resulting in a broker non-vote with respect to such proposals.

Can I Change My Vote after I Submit My Proxy?

Registered Stockholder: Shares Registered in Your Name

If you are the registered stockholder, you may revoke your proxy at any time before the final vote at the Annual Meeting in any one of the following ways:

Your last submitted vote is the one that will be counted.

4

Beneficial Owner: Shares Registered in the Name of a Broker, Fiduciary, or Custodian

If you are the beneficial owner, you must follow the instructions you receive from your broker, fiduciary, or custodian with respect to changing your vote.

What Is the Quorum Requirement?

The holders of a majority of the shares of common stock outstanding and entitled to vote at the Annual Meeting must be present at the Annual Meeting, either virtually or represented by proxy, to constitute a quorum. A quorum is required to transact business at the Annual Meeting.

Your shares will be counted toward the quorum only if you submit a valid proxy (or a valid proxy is submitted on your behalf by your broker, fiduciary, or custodian) or if you attend the Annual Meeting virtually and vote. Abstentions and broker non-votes will be counted toward the quorum requirement. If there is no quorum, the chairman of the Annual Meeting or the holders of a majority of shares of common stock virtually present at the Annual Meeting, either personally or by proxy, may adjourn the Annual Meeting to another time or date.

How Many Votes Are Required to Approve Each Proposal and How Are Votes Counted?

Votes will be counted by a representative of Mediant, who has been appointed as the independent Inspector of Elections for the Annual Meeting.

Proposal 1: Election of Directors

A nominee will be elected as a director at the Annual Meeting if the nominee receives a plurality of the votes cast “FOR” their election. “Plurality” means that the individuals who receive the largest number of votes cast “FOR” are elected as directors. Broker non-votes, if any, and votes that are withheld will not be counted as votes cast on the proposal and will have no effect on the outcome of the election. Stockholders do not have cumulative voting rights for the election of directors.

Proposal 2: Approval of an Amendment and Restatement of the Stem, Inc. 2024 Equity Incentive Plan

The affirmative vote of at least a majority of the shares of common stock present or represented at the Annual Meeting and entitled to vote thereon is required for the approval of an amendment and restatement of the Stem, Inc. 2024 Equity Incentive Plan. Abstentions will have the same effect as a vote “against” the proposal. Broker non-votes, if any, will have no effect on the outcome of this proposal.

Proposal 3: Non-binding, Advisory Approval of Named Executive Officer Compensation

The affirmative vote of a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote thereon is required for the non-binding, advisory approval of named executive officer compensation. Abstentions will have the same effect as a vote “against” the proposal. Broker non-votes, if any, will have no effect on the outcome of this proposal.

Proposal 4: Ratification of Independent Auditor Selection

The affirmative vote of a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote thereon is required for the ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2025. Abstentions will have the same effect as a vote “against” the proposal. Broker non-votes, if any, will have no effect on the outcome of this proposal.

5

Proposal 5: Approval of a Reverse Stock Split

The affirmative vote of a majority of the votes cast is required for the approval of the reverse stock split. Abstentions and broker non-votes, if any, will not be counted as votes cast on the proposal and will have no effect on the outcome of this proposal.

Proposal 6: Approval of a Reduction in the Number of Authorized Shares of Common Stock

The affirmative vote of a majority of the votes cast is required for the approval of the authorized share reduction. Abstentions and broker non-votes, if any, will not be counted as votes cast on the proposal and will have no effect on the outcome of this proposal.

Proposal 7: Approval of an Adjournment of the Annual Meeting

The affirmative vote of a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote thereon is required for the approval of the adjournment of the Annual Meeting. Abstentions will have the same effect as a vote “against” the proposal. Broker non-votes, if any, will have no effect on the outcome of this proposal.

Who Is Paying for This Proxy Solicitation?

We will pay the costs associated with the solicitation of proxies, including the preparation, assembly, printing, and mailing of the proxy materials. We have retained D.F. King & Co., Inc. and its affiliate to assist in the solicitation of proxies for a fee estimated at $5,250 plus reasonable expenses. Our employees, officers, and directors may solicit proxies in person or via telephone or the Internet. We will not pay additional compensation for any of these services. We may also reimburse brokers, fiduciaries, or custodians for the cost of forwarding proxy materials to beneficial owners of shares of common stock held in “street name.”

How Can I Find out the Voting Results?

We expect to announce preliminary voting results at the Annual Meeting. We will disclose final voting results in a Current Report on Form 8-K that we will file with the SEC within four business days after the Annual Meeting.

PROPOSAL 1: ELECTION OF DIRECTORS

Our Board is currently divided into three classes, with members of each class holding office for staggered three-year terms.

There are currently two Class I directors who are up for election at the Annual Meeting to serve for terms expiring at the 2028 Annual Meeting of Stockholders; three Class II directors, whose terms expire at the 2026 Annual Meeting of Stockholders; and two Class III directors, whose terms expire at the 2027 Annual Meeting of Stockholders, in all cases until their successors have been duly elected and qualified or until the earlier of their resignation or removal.

PROPOSAL 2: APPROVAL OF AN AMENDMENT AND RESTATEMENT OF

THE STEM, INC. 2024 EQUITY INCENTIVE PLAN

Executive Summary

The Company’s stockholders previously approved the Stem, Inc. 2024 Equity Incentive Plan (referred to for purposes of this Proposal 2 as the “Plan”) on May 29, 2024 (the “Original Effective Date”), under which employees, directors, and consultants may be granted equity-based incentive awards. At the Annual Meeting, stockholders will be asked to approve an amendment and restatement of the Plan, which was approved by the Board on February 13, 2025 (the “2025 Restatement”).

The 2025 Restatement would increase the number of shares of Stem’s common stock that may be issued under the Plan by 7,500,000 shares (the “Additional Shares”), less the number of shares subject to awards granted after March 31, 2025 and prior to the effective date of the 2025 Restatement (the “Effective Date”). The Company believes that this increase is advisable in order to ensure that the Company has an adequate number of shares available in connection with its incentive compensation programs.

The 2025 Restatement would also extend the term of the Plan through the tenth anniversary of the Effective Date.

The text of the Plan, as proposed to be amended by the 2025 Restatement, appears at the end of this Proxy as Appendix A. The following description of the 2025 Restatement is a summary only and should be read in conjunction with the full text of the 2025 Restatement.

Reasons for the Proposal

The Board unanimously recommends that the Company’s stockholders approve the 2025 Restatement. The Company’s ability to grant an appropriate number of equity-based awards continues to be crucial in helping the Company compete more effectively for key employee talent. It is in the long-term interest of the Company and its stockholders to strengthen the ability to attract, motivate, and retain officers, directors, employees, advisors and consultants, and to provide additional incentive for those persons through stock ownership and other incentives to improve operations, increase profits, and strengthen the mutuality of interest between those persons and the Company’s stockholders.

If the 2025 Restatement is not approved, the number of shares currently available under the Plan is not projected to be sufficient to cover all of our future equity compensation needs. Thus, if the 2025 Restatement is not approved, we may not be able to provide persons eligible for awards who are presently providing services to the Company with compensation packages that are necessary to retain and motivate these individuals. In addition, if the 2025 Restatement is not approved, we may not be able to provide potential new hires with compensation packages necessary to attract them.

Material Differences From the Plan

The Additional Shares

The 2025 Restatement would add 7,500,000 shares to the reserve available for future grants. This increased share reserve would allow the Company to continue to grant a variety of equity-based compensation alternatives in structuring compensation arrangements for our key talent, including officers, directors, employees, advisors and consultants, and to attract potential new service providers through competitive compensation packages.

Our stock plan is a critical tool for motivating and retaining key talent both at the executive level and further down in the organization. Five-Hundred-sixteen (516) of our 556 employees on March 31, 2025 held outstanding

16

equity awards (i.e., 92.8% participation), and we made equity grants to 77% of our employees during 2024. If the Additional Shares are not approved then we will not be able to make competitive equity awards after 2025 and we would risk losing key talent at various employee levels who are critical to executing our turnaround plan.

Under the existing share reserve, as of March 31, 2025, there were approximately 15,786,108 shares subject to outstanding equity awards under the Plan, and approximately 5,574,979 shares available for future grants under the Plan.

Key Data

When approving the 2025 Restatement, the Board considered the “burn rate” with respect to the equity awards granted by the Company, as well as the Company’s “fully-diluted overhang.” The burn rate is equal to the total number of equity awards the Company granted in a fiscal year, divided by the weighted average common stock outstanding during the year. Fully-diluted overhang is equal to the total number of equity awards outstanding plus the total number of shares available for grant under the Company’s equity plans, divided by the sum of the total number of equity awards outstanding plus the total number of shares available for grant under the Company’s equity plans plus total common stock outstanding.

The Company’s three-year average burn rate for the last three fiscal years was approximately 6.4% (which consisted of 4.5% in 2022, 5.8% in 2023, and 8.9% in 2024).

The Company’s fully-diluted overhang as of March 31, 2025 was 11.4%. If the 2025 Restatement is approved, the Company’s overhang would increase to 14.8%.

17

The table below shows the stock awards that were outstanding under Plan as of March 31, 2025.

While the Company recognizes the significant motivational and performance benefits that may be achieved from granting equity awards, Stem is also mindful of the potential dilutive effect of such awards and the Company’s responsibility to our shareholders. The Board believes that the Additional Shares represent a reasonable amount of potential equity dilution and would allow the Company to continue granting equity awards, which is an important component of the Company’s overall compensation plan. The number of Additional Shares was determined in part based on our average burn rate over the last three years and is needed to allow the Company to make equity-based grants during the remainder of 2025 and in 2026 (and potentially in 2027, depending on various factors including our award forfeiture rate). We anticipated at the time of our 2024 share request that the total stock plan pool at the time would last for two years, but our share price decreased significantly which contributed to a greater-than-anticipated number of shares granted through March 31, 2025, and we also needed to use additional shares to make new-hire grants to key senior executive hires including our CEO and our CFO.

Plan Summary

The following summary of the material terms of the 2025 Restatement is qualified in its entirety by reference to the complete text of the 2025 Restatement, which is set forth in Appendix A. Stockholders are encouraged to read the text of the 2025 Restatement in its entirety.

Purpose

The 2025 Restatement is intended to help the Company secure and retain the services of eligible award recipients, provide incentives for such persons to exert maximum efforts for the success of the Company and its affiliates and provide a means by which the eligible award recipients may benefit from increases in the value of our common stock.

Administration

The Board has the authority to administer the 2025 Restatement, including the powers to: (i) determine who will be granted awards and what type of award, when and how each award will be granted, the provisions of each award (which need not be identical), the number of shares or cash value subject to an award and the fair market value applicable to an award; (ii) construe and interpret the 2025 Restatement and awards granted thereunder and establish, amend and revoke rules and regulations for administration of the 2025 Restatement and awards, including the ability to correct any defect, omission or inconsistency in the 2025 Restatement or any award document; (iii) settle all controversies regarding the 2025 Restatement and awards granted thereunder; (iv) accelerate or extend, in whole or in part, the time during which an award may be exercised or vested or at which cash or shares may be issued; (v) suspend or terminate the 2025 Restatement at any time, including to impose a “blackout” or other periods during which awards may not be exercised or settled; (vi) amend the 2025 Restatement; (vii) submit any amendment to the 2025 Restatement for stockholder approval; (viii) approve forms of award documents for use under the 2025 Restatement and amend the terms of any one or more outstanding awards; (ix) generally exercise such powers and perform such acts as the Board may deem necessary or expedient to promote the best interests of the Company and that are not in conflict with the provisions of the 2025 Restatement or any award documents; and (x) adopt procedures and sub-plans as are necessary or appropriate.

The Board may delegate some or all administration of the 2025 Restatement to a committee consisting solely of two or more non-employee directors and/or to an officer in accordance with the provisions of and subject to the terms set forth in the 2025 Restatement. All determinations, interpretations and constructions made by the Board (or another authorized committee or officer exercising powers delegated by the Board) in good faith will be final, binding and conclusive on all persons.

Eligible Participants

Awards may be granted to employees, including officers, directors and certain consultants of the Company and its affiliates. As of March 31, 2025, approximately 504 employees and seven non-employee directors were eligible to participate in the Plan. Options intending to qualify as incentive stock options (“ISOs”) within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”) may only be granted to employees of the Company or any qualifying Company subsidiary.

Available Shares

Subject to adjustment for certain dilutive or related events and as described below, if approved by stockholders, the aggregate number of shares of common stock that will be available for issuance under the 2025

19

Restatement, or the Share Reserve, will be as of the Effective Date will be 13,074,979 (which is the sum of the 5,574,979 shares remaining available for grant under the Plan as of March 31, 2025 plus the Additional Shares ), less one share for every one share granted under the Plan after March 31, 2025 and prior to the Effective Date. In addition, the Share Reserve may be increased by any shares of common stock subject to outstanding awards under the 2019 Plan that, on or after the Original Effective Date, cease for any reason to be subject to such awards (other than by reason of exercise or settlement of the awards to the extent they are exercised for or settled in vested and nonforfeitable shares of common stock).

The Share Reserve will not be reduced if an award or any portion thereof (i) expires, is cancelled or forfeited or otherwise terminates without all of the shares covered by such award having been issued or (ii) is settled in cash. If any shares of common stock under an award are forfeited back to, reacquired at no cost by, or repurchased at cost by the Company because of the failure to meet a contingency or condition required to vest such shares in the participant, such shares will revert to and again be made available for issuance under the 2025 Restatement. Notwithstanding the foregoing, the following shares of common stock will not be recredited to the Share Reserve: (x) shares of common stock not issued or delivered as a result of the net settlement of an outstanding stock award, (y) shares of common stock used to pay the exercise price or withholding taxes related to any outstanding stock award, or (z) shares of common stock reacquired by the Company with the amount received upon exercise of an option.

The aggregate number of shares of common stock that may be issued on the exercise of ISOs is 13,074,979.

Shares issued under the 2025 Restatement may consist of authorized by unissued or reacquired common stock of the Company, including shares repurchased by the Company on the open market or otherwise or shares classified as treasury shares.

Non-Employee Director Compensation Limit

The maximum number of shares of common stock subject to awards granted during a single fiscal year to any non-employee director, together with any cash fees paid to such non-employee director during such fiscal year in respect of such non-employee director’s service as a member of the Board during such fiscal year, will not exceed a total value of $600,000 (calculating the value of any awards based on the grant date fair value in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto) (“ASC Topic 718”)). Notwithstanding the foregoing, the Board may provide, in its discretion, for exceptions to this limit for a non-employee director, provided that the non-employee director receiving such additional compensation may not participate in the decision to award such compensation.

Termination and Amendment

The Board may amend the 2025 Restatement as it deems necessary or advisable. To the extent required by applicable law or listing requirements, the Company will seek stockholder approval of any amendment of the 2025 Restatement that materially (A) increases the number of shares available for issuance under the 2025 Restatement, (B) expands the class of individuals eligible to receive awards, (C) increases the benefits accruing to participants under the 2025 Restatement, (D) reduces the price at which shares of common stock may be issued or purchased under the 2025 Restatement, (E) extends the term of the 2025 Restatement, or (F) expands the types of awards available for issuance under the 2025 Restatement. Except as otherwise provided in the 2025 Restatement or an award document, no amendment of the 2025 Restatement may materially impair a participant’s rights under an outstanding award without the participant’s written consent. The Board or the Compensation Committee of the Board may suspend or terminate the 2025 Restatement at any time. The 2025 Restatement will automatically terminate on the tenth anniversary of the Effective Date, provided, however, that ISOs may not be granted more than ten (10) years after the later of (i) April 19, 2024 (which is the original date of approval of the Plan by the Board) and (ii) the adoption by the Board of any amendment to the 2025

20

Restatement that constitutes the adoption of a new plan for purposes of Section 422 of the Code. No awards may be granted under the 2025 Restatement while the 2025 Restatement is suspended or terminated.

Awards

The 2025 Restatement authorizes the Board to grant awards to eligible participants, any of which may be subject to the achievement of performance goals, in the form of incentive and nonstatutory stock options, SARs, restricted stock, and RSUs.

Stock Options

A stock option may be granted as an ISO or a stock option which is not intended qualify as an ISO (a “nonstatutory stock option”). The option exercise price may not be less than the fair market value of the stock subject to the option on the date of grant (or, with respect to ISOs, may not be less than 110% of the fair market value if the recipient owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or any affiliate, who we refer to herein as a “Ten Percent Stockholder”), unless the option was granted pursuant to an assumption or substitution for another option in a manner satisfying the provisions of Section 409A and, if applicable, Section 424(a) of the Code. Options will not be exercisable after the expiration of ten years from the date of grant (or after five years, in the case of an ISO issued to a Ten Percent Stockholder).

Each award agreement will set forth the number of shares subject to each option. The purchase price of any shares acquired pursuant to an option may be payable either by cash, check, bank draft, money order, or, as determined by the Board in its sole discretion, by any combination of: net exercise (but only if the option is a nonstatutory stock option), through an irrevocable commitment by a broker to pay over such amount from a sale of the shares issuable under the option, the delivery of previously owned shares, and any other form of legal consideration that may be acceptable to the Board. The vesting schedule applicable to any option, including any performance goals, will be as set forth in the award agreement.

Stock Appreciation Rights

A SAR is a right that entitles the participant to receive upon exercise, in cash, shares of stock or a combination thereof, as determined by the Board, value equal to or otherwise based on the excess of (i) the fair market value of a specified number of shares at the time of exercise over (ii) the exercise price of the right, as established by the Board on the date of grant. The exercise price of each SAR may not be less than the fair market value of the stock subject to the award on the date the SAR is granted, unless the SAR was granted pursuant to an assumption of or substitution for another option in a manner satisfying the provisions of Section 409A of the Code. SARs will not be exercisable after the expiration of ten years from the date of grant. Each award agreement will set forth the number of shares subject to the SAR and the vesting schedule applicable thereto, including any performance goals.

Provisions Applicable to Both Stock Options and Stock Appreciation Rights

Transferability. The Board may, in its sole discretion, impose limitations on the transferability of options and SARs. Unless the Board provides otherwise, an option or SAR will not be transferable except by will or the laws of descent and distribution and will be exercisable during the lifetime of a participant only by such participant. The Board may permit transfer of an option or SAR in a manner not prohibited by applicable law, except an option or SAR may never be transferred to a third-party financial institution for value. Subject to approval by the Board, an option or SAR may be transferred pursuant to the terms of a domestic relations order or similar instrument and participants may designate a beneficiary who following the participant’s death will be entitled to exercise the option or SAR.

Termination of Service. Except as otherwise provided in an applicable award document or other agreement between a participant and the Company, upon a participant’s termination for any reason other than for cause or

21

due to death or disability, a participant may exercise his or her option or SAR (to the extent such award was exercisable as of the date of termination) for a period of three months following the termination date or, if earlier, until the expiration of the original term of such award. Upon a participant’s termination due to a participant’s disability, unless otherwise provided in an applicable award or other agreement, the participant may exercise his or her option or SAR (to the extent that such award was exercisable as of the date of termination) for a period of 12 months following the termination date or, if earlier, until the expiration of the original term of such award. Upon a termination due to a participant’s death, unless otherwise provided in an applicable award or other agreement, the participant’s estate may exercise the option or SAR (to the extent such award was exercisable as of the termination date) for a period of 18 months following the date of death or, if earlier, until the expiration of the original term of such award. Unless provided otherwise in an award or other agreement, if a participant is terminated for cause, such participant’s option or SAR will terminate on the date the event giving rise to the termination for cause first occurred and the participant will not be permitted to exercise such award.

No Dividends or Dividend Equivalents. No options or SARs may provide for the payment of dividends or dividend equivalents thereon.

No Repricing. Options and SARs may not be modified to reduce the exercise price thereof nor may (i) a new option, SAR or other award at a lower price be substituted or exchanged for a surrendered option or SAR, (ii) any option or SAR with an exercise price that exceeds the fair market value of a share be exchanged for a new option, SAR, cash or other consideration (other than in connection with a change in control), or (iii) any action be taken that would be considered a “repricing” of an option or SAR under the applicable listing standards of the national securities exchange on which the Company’s common stock is listed, unless such action is approved by the stockholders of the Company and otherwise as permitted in the event of certain equitable adjustments.

Restricted Stock and Restricted Stock Units

Restricted shares are awards of shares, the grant, issuance, retention, vesting or transferability of which is subject to such conditions (including continued employment or the satisfaction of performance goals, or both) and terms as the Board deems appropriate. RSUs are awards denominated in units under which the issuance of shares (or cash payment in lieu thereof) is subject to such conditions (including continued employment and/or the satisfaction of performance goals) and terms as the Board deems appropriate. Each award document evidencing a grant of restricted stock or RSUs will set forth the terms and conditions of each award, including vesting and forfeiture provisions, and transferability. No dividends or dividend equivalents shall be paid or settled with respect to such awards unless and until, and then only to the extent that, the underlying award vests.

Performance Goals

The Board, the Compensation Committee of the Board, or an authorized officer, as the case may be, may establish performance criteria, performance period, and level of achievement versus such criteria that will determine the number of shares or units to be granted, retained, vested, issued, or issuable under or in settlement of or the amount payable pursuant to an award. The Board, the Compensation Committee of the Board, or an authorized officer, as the case may be, also retains the discretion to define the manner of calculating the performance criteria it selects.

In determining the outcome of a performance goal or performance-based vesting award, the Committee may provide for exclusion of the impact of an event or occurrence which the Committee determines should appropriately be excluded, including (a) restructurings, discontinued operations, extraordinary items, and other unusual, infrequently occurring or non-recurring charges or events, (b) asset write-downs, (c) litigation or claim judgments or settlements, (d) acquisitions or divestitures, (e) reorganization or change in the corporate structure or capital structure of the Company, (f) an event either not directly related to the operations of the Company, Subsidiary, division, business segment or business unit or not within the reasonable control of management,

22

(g) foreign exchange gains and losses, (h) a change in the fiscal year of the Company, (i) the refinancing or repurchase of bank loans or debt securities, (j), unbudgeted capital expenditures, (k) the issuance or repurchase of equity securities and other changes in the number of outstanding shares, (l) conversion of some or all of convertible securities to common stock, (m) any business interruption event, (n) the cumulative effects of tax or accounting changes in accordance with U.S. generally accepted accounting principles, or (o) the effect of changes in other laws or regulatory rules affecting reported results.

Minimum Vesting Requirements

Stock awards granted under the 2025 Restatement may not become exercisable, vest or be settled, in whole or in part, prior to the one-year anniversary of the date of grant except (i) with respect to an award that is granted in connection with a merger or other acquisition as a substitute or replacement award for awards held by participants of the acquired business and (ii) with respect to an award granted to a non-employee director that vests on the earlier of the one-year anniversary of the date of grant and the next annual meeting of stockholders which is at least 50 weeks after the immediately preceding year’s annual meeting; provided, that (x) up to 5% of the Share Reserve may be issued pursuant to awards that are subject to vesting periods of less than one year, and (y) provided, further, that the foregoing restriction does not apply to the Board’s discretion to provide for accelerated exercisability or vesting of any award, including in cases of retirement, death, disability or a change in control, in the terms of the award or otherwise.

Adjustments of and Changes in the Stock

In the event of any change in the capitalization of the Company, the Board will appropriately and proportionately adjust: (i) the class(es) and maximum number of securities subject to the 2025 Restatement; (ii) the class(es) and maximum number of securities that may be issued pursuant to the exercise of ISOs; and (iii) the class(es) and number of securities or other property and value (including price per share of stock) subject to outstanding stock awards. The Board will make such adjustments, and its determination will be final, binding and conclusive. Unless provided otherwise in an award or other agreement, in the event of a dissolution or liquidation of the Company, all outstanding stock awards (other than stock awards consisting of vested and outstanding shares of Company common stock not subject to a forfeiture condition or the Company’s right of repurchase) will terminate immediately prior to the completion of such dissolution or liquidation, and the shares of common stock subject to the Company’s repurchase rights or subject to forfeiture may be repurchased or reacquired by the Company notwithstanding the fact that the holder of such stock award is providing continuous service; provided, however, that the Board may, in its sole discretion, provide that some or all stock awards will become fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent not already expired or terminated) before the dissolution or liquidation is completed but contingent upon its completion.

In the event of a Change in Control (as defined in the 2025 Restatement), the Board will take one or more of the following actions with respect to each outstanding award, contingent upon the closing or completion of the Change in Control:

23

The Board need not take the same action with respect to all awards or portions thereof or with respect to all participants and may take different actions with respect to the vested and unvested portions of an award.

In the absence of any affirmative determination by the Board at the time of a Change in Control, each outstanding award will be assumed or an equivalent award will be substituted by such successor corporation or a parent or subsidiary thereof, unless such successor corporation does not agree to assume or substitute the award, in which case the vesting of such award will accelerate (along with, if applicable, the time at which the award may be exercised) to a date prior to the effective time of such Change in Control as the Board will determine (or, if the Board will not determine such a date, to the date that is five days prior to the effective date of the Change in Control), with such award terminating if not exercised (if applicable) at or prior to the effective time of the Change in Control, and with such exercise reversed if the Change in Control does not become effective.

An award may be subject to additional acceleration of vesting and exercisability upon or after a Change in Control as may be provided in the award agreement for such award or as may be provided in any other written agreement with the participant, but in the absence of such provision, no such acceleration will occur.

U.S. Federal Income Tax Consequences

The following discussion of the federal income tax consequences of the 2025 Restatement is intended to be a summary of applicable U.S. federal law as currently in effect. The discussion is intended solely for general information purposes and does not make specific representations to any participant. The discussion does not address state, local, or foreign income tax rules or other U.S. tax provisions, such as estate or gift taxes. A participant’s particular situation may be such that some variation of the basic rules is applicable to them. In addition, the federal income tax laws and regulations frequently have been revised and may be changed again at any time. Therefore, each participant is urged to consult a tax advisor before exercising any award or before disposing of any shares acquired under the 2025 Restatement both with respect to federal income tax consequences as well as any state, local, or foreign tax consequences.

Stock Options

ISOs and nonstatutory stock options are treated differently for federal income tax purposes. ISOs are intended to comply with the requirements of Section 422 of the Code and nonstatutory stock options are not intended to comply with such requirements.

An optionee generally does not recognize taxable income on the grant or exercise of an ISO. The difference between the exercise price and the fair market value of the shares on the exercise date (the “Spread Value”) may, however, be a preference item for purposes of the alternative minimum tax. If an optionee holds the shares

24

acquired upon exercise of an ISO for at least two years following the option grant date and at least one year following exercise, the optionee’s gain, if any, upon a subsequent disposition of such shares will be taxed as long-term capital gain. The measure of the gain is the difference between the proceeds received on disposition and the optionee’s basis in the shares (which generally equals the exercise price). If an optionee disposes of stock acquired pursuant to the exercise of an ISO before satisfying these holding periods, the optionee will recognize ordinary income in the year of disposition in an amount equal to the excess of the fair market value of the shares at the time of exercise (or, if less, the amount realized on the disposition of the shares), over the exercise price paid for the shares, and any additional gain or loss recognized upon the disposition will be a capital gain or loss. The Company is not entitled to an income tax deduction on the grant or exercise of an ISO or on the optionee’s disposition of the shares after satisfying the holding period requirement described above. If the holding periods are not satisfied, the Company will be entitled to a deduction in the year the optionee disposes of the shares in an amount equal to the ordinary income recognized by the optionee.

In order for an option to qualify for ISO tax treatment, the grant of the option must satisfy various other conditions more fully described in the Code. The Company does not guarantee that any option will qualify for ISO tax treatment even if the option is intended to qualify for such treatment. In the event an option intended to be an ISO fails to so qualify, it will be taxed as a nonstatutory stock option as described below.

An optionee is not taxed on the grant of a nonstatutory stock option. On exercise, the optionee recognizes ordinary income equal to the Spread Value on the date of exercise. The Company is entitled to an income tax deduction in the year of exercise in the amount recognized by the optionee as ordinary income. The optionee’s gain (or loss) on a subsequent disposition of the shares will be long-term or short-term capital gain (or loss) depending on the holding period of such shares following exercise. The Company does not receive a deduction for any such gain.

Stock Appreciation Rights

A participant is not taxed on the grant of a SAR. On exercise, the participant recognizes ordinary income equal to the Spread Value. The Company is entitled to an income tax deduction in the year of exercise in the amount recognized by the participant as ordinary income.

Restricted Stock

Participants who receive restricted stock will not recognize any taxable income at the time those shares are granted but will have to report as ordinary income, as and when those shares subsequently vest, an amount equal to the excess of (i) the fair market value of the shares on the vesting date over (ii) the cash consideration (if any) paid for the shares. The participant may, however, elect under Section 83(b) of the Code within 30 days of the grant date to include as ordinary income in the year the unvested shares are granted an amount equal to the excess of (a) the fair market value of those shares on the grant date over (b) the cash consideration (if any) paid for such shares. If the Section 83(b) election is made, the participant will not recognize any additional income as and when the shares subsequently vest and if the participant forfeits the shares to the Company (e.g., upon the participant’s termination prior to vesting), the participant may not claim a deduction with respect to the income recognized as a result of the election. The Company will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the participant at the time such ordinary income is recognized by the participant.

Restricted Stock Units

Participants who receive RSUs do not recognize income at the time of the grant. When the RSUs vest, participants generally recognize ordinary income in an amount equal to the fair market value of the stock, cash, or other consideration received in settlement of the RSUs, and the Company will receive a corresponding income tax deduction.

25

Company Deduction and Section 162(m)

Section 162(m) of the Code generally limits the federal income tax deduction for compensation paid to “covered employees” (in general, the CEO, the CFO, and the three other most highly-compensated executive officers for the year at issue and any person who was part of that group for any other year beginning after December 31, 2016) to $1,000,000. It is expected that compensation deductions for any covered employee with respect to awards granted under the 2025 Restatement will be subject to the $1,000,000 annual deduction limitation. The Board may grant awards under the 2025 Restatement or otherwise that are or may become non-deductible when it believes doing so is in the best interests of the Company and our stockholders.

Withholding Taxes

The Company will generally be required to withhold applicable taxes with respect to any ordinary income recognized by a participant who is an employee in connection with awards made under the 2025 Restatement.

THE FOREGOING IS ONLY A SUMMARY OF THE EFFECTS OF U.S. FEDERAL INCOME TAXATION UPON PARTICIPANTS AND STEM WITH RESPECT TO AWARDS UNDER THE 2025 RESTATEMENT. IT DOES NOT PURPORT TO BE COMPLETE, AND DOES NOT DISCUSS THE IMPACT OF EMPLOYMENT OR OTHER TAX REQUIREMENTS, THE TAX CONSEQUENCES OF A PARTICIPANT’S DEATH OR THE PROVISIONS OF THE INCOME TAX LAWS OF ANY MUNICIPALITY, STATE OR FOREIGN COUNTRY IN WHICH THE PARTICIPANT MAY RESIDE.

Existing Plan Benefits

No awards made under the Plan prior to the date of the Annual Meeting were granted subject to stockholder approval of this Proposal 2. The following table sets forth information with respect to stock options and stock awards that have been granted to our named executive officers and the specified groups set forth below under the Plan as of March 31, 2025.

26

New Plan Benefits; Market Value of Securities

The benefits that will be awarded or paid in the future under the 2025 Restatement are not currently determinable. Such awards are within the discretion of the Board or its Compensation Committee, and neither the Board nor the Compensation Committee has determined future awards or who might receive them. Therefore, a New Plan Benefits Table is not provided. As of March 31, 2025, the closing price of a share of the Company’s common stock was $0.35.

Registration With the SEC

Assuming that stockholders approve the 2025 Restatement, we intend to file with the SEC a registration statement on Form S-8 covering the Additional Shares in the second quarter of calendar year 2025.

Required Vote

The affirmative vote of a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote thereon is required for the approval of the amendment and restatement of the 2024 Equity Incentive Plan. Abstentions will have the same effect as a vote “against” this proposal. Broker non-votes, if any, will have no effect on the outcome of this proposal.

Recommendation of the Board

The Board unanimously recommends that you vote “FOR” the approval of the amendment and restatement of the Company’s 2024 Equity Incentive Plan.

27

PROPOSAL 3: NON-BINDING, ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION

Our Board is asking you to approve, on a non-binding, advisory basis, the compensation of our named executive officers (“NEOs”), as disclosed in this Proxy Statement. This item, which is provided pursuant to Section 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is commonly referred to as a “say-on-pay” resolution.

This say-on-pay proposal gives our stockholders the opportunity to express their views on our NEOs’ compensation as a whole. This vote is not intended to address any specific element of compensation but rather the overall compensation of our NEOs and our compensation philosophy, policies, and practices described in this Proxy Statement. Please read the “Executive Compensation” section and the compensation tables and narrative disclosure that follow for information about our executive compensation program, including details of the 2024 compensation of our NEOs. Our Compensation Committee believes that these policies and practices are effective in implementing our compensation philosophy and achieving our compensation program goals.

As an advisory vote, the outcome of the vote on this proposal is not binding. However, our Compensation Committee, which is responsible for designing and administering our executive compensation program, will consider the outcome of this vote when making future executive compensation decisions. Unless our Board modifies its current policy on the frequency of holding say-on-pay votes, the next say-on-pay vote is expected to occur at our 2026 Annual Meeting of Stockholders.

Required Vote

The affirmative vote of a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote thereon is required for the non-binding, advisory approval of our named executive officers’ compensation. Abstentions will have the same effect as a vote “against” this proposal. Broker non-votes, if any, will have no effect on the outcome of this proposal.

Recommendation of the Board

The Board recommends a vote “FOR” the approval, on a non-binding, advisory basis, of our named executive officers’ compensation.

PROPOSAL 4: RATIFICATION OF INDEPENDENT AUDITOR SELECTION

Our Audit Committee has selected Deloitte & Touche LLP (“Deloitte”) as the Company’s independent registered public accounting firm for the year ending December 31, 2025. In this proposal, we are asking stockholders to vote to ratify this selection. Representatives of Deloitte are expected to be present at the Annual Meeting. They will have the opportunity to make a statement, if they desire to do so, and will be available to respond to appropriate questions from stockholders.

Stockholder ratification of the selection of Deloitte as the Company’s independent registered public accounting firm is not required by law or our Bylaws. However, we are seeking stockholder ratification as a matter of good corporate practice. If our stockholders fail to ratify the selection, our Audit Committee will reconsider its selection. Even if the selection is ratified, the Audit Committee, in its discretion, may direct the selection of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and our stockholders.

Deloitte has served as our independent registered public accounting firm since August 2021, and provided services to Legacy Stem from 2018 until the Merger. The following table summarizes the audit fees billed and expected to be billed by Deloitte for the indicated fiscal years and the fees billed by Deloitte for all other services rendered during the indicated fiscal years. All services associated with such fees were pre-approved by our Audit Committee in accordance with the “Pre-Approval Policies and Procedures” described below.

Pre-Approval Policy and Procedures

Our Audit Committee has adopted procedures requiring the pre-approval of all audit and permissible non-audit services performed by our independent registered public accounting firm. In its pre-approval and review of non-audit service fees, the Audit Committee considers, among other factors, the possible effect of the performance of such services on the auditors’ independence.

These procedures generally approve the performance of specific services subject to a cost limit for all such services. This general approval is reviewed, and if necessary modified, at least annually. The Committee may pre-approve certain other audit-related or other non-audit services it believes would not impair the independence of the auditor and are consistent with SEC and Public Company Accounting Oversight Board (“PCAOB”) rules on auditor independence. The Committee does not delegate its responsibility to approve services performed by our auditor to any member of management. The Committee has delegated authority to the Committee chair to pre-approve any audit or non-audit service to be provided to us by our auditor provided that the fees for such services do not exceed $150,000, (1) per each engagement or project, (2) per each additional category of services,

29

or (3) to the extent required under such procedures, for any individual service exceeding the pre-approved budgeted fee levels for the specified service, in each case with such limit applying to each individual engagement/project, service or category of services being approved by the Committee chair and not on an aggregated or quarterly/annual basis. Any approval of services by the Committee chair pursuant to this delegated authority must be reported to the Committee at its next regularly scheduled meeting.

Required Vote

The affirmative vote of a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote thereon is required for the ratification of the selection of Deloitte as our independent registered public accounting firm for the year ending December 31, 2025. Abstentions will have the same effect as a vote “against” this proposal. Broker non-votes, if any, will have no effect on the outcome of this proposal.

Recommendation of the Board

The Board recommends that you vote “FOR” the ratification of the selection of Deloitte as our independent registered public accounting firm for fiscal year 2025.

PROPOSED AMENDMENTS TO THE CERTIFICATE OF INCORPORATION: PROPOSALS 5 AND 6

Background

We are asking our stockholders to approve two amendments to our Second Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”), which the Board has approved and declared advisable, to effect:

The primary purpose of the Reverse Stock Split is to raise the per share trading price of our common stock by reducing the number of outstanding shares in order to maintain our listing on the New York Stock Exchange (“NYSE”). On August 28, 2024, we received written notice (the “Notification Letter”) from NYSE notifying us that we were not in compliance with the minimum average closing price required to maintain continued listing on the NYSE under Section 802.01C of the NYSE Listed Company Manual (the “Price Criteria Rule”). The NYSE rules provide for a cure period of six months following receipt of the Notification Letter to regain compliance, and in order to do so, on the last trading day of any calendar month during the cure period, our common stock must have had a closing share price of at least $1.00 per share and an average closing price of at least $1.00 per share over the 30-trading-day period ending on the last trading day of such month. The NYSE rules also provide for an exception to the six-month cure period if the action required to cure the Price Criteria Rule requires stockholder approval, in which case, the action needs to be approved by stockholders by no later than the Company’s next annual meeting of stockholders and promptly implemented. The Price Criteria Rule will be deemed cured if our share price promptly exceeds $1.00 per share after receiving stockholder approval, and the price remains above that level for at least the following 30 trading days. On February 13, 2025, we notified the NYSE that we intend to regain compliance with the Price Criteria Rule through a reverse stock split, for which we would seek stockholder approval no later than at the Annual Meeting. As of February 28, 2025, the last day of the initial six-month cure period, our common stock traded below the required closing share price of at least $1.00 per share. As such, regardless of any subsequent increases in our share price above $1.00 per share, under NYSE rules, we are required to seek stockholder approval for and to implement a reverse stock split.

The Authorized Shares Reduction is designed to avoid what some stockholders might view as an unreasonably high number of authorized, but unissued and unreserved, shares following a Reverse Stock Split; as such, the implementation of the Authorized Shares Reduction is expressly conditioned upon the implementation of the Reverse Stock Split. If stockholders approve both Proposals 5 and 6 and the Board determines to implement the Reverse Stock Split at certain ratios, the Board will also implement the Authorized Shares Reduction. However, if stockholders approve Proposal 5 but not Proposal 6, the Board may still determine to implement the Reverse Stock Split without the Authorized Shares Reduction.

Effectiveness of Amendments

The text of the proposed form of Certificate of Amendment to our Certificate of Incorporation (the “Certificate of Amendment”) is attached hereto as Appendix B. If approved by stockholders and implemented by the Board, the Reverse Stock Split and the Authorized Shares Reduction will become effective upon the filing of the Certificate of Amendment with the Secretary of State of the State of Delaware, or such later date as is chosen by the Board and set forth in the Certificate of Amendment (the “Effective Date”). We will publicly announce the Reverse Stock Split ratio chosen by the Board prior to the Effective Date.

31

No Dissenter’s or Appraisal Rights

Under the Delaware General Corporation Law, stockholders are not entitled to dissenter’s or appraisal rights with respect to Proposals 5 or 6, or the corresponding amendments to our Certificate of Incorporation.

Interest of Certain Persons in Matter to be Acted Upon

No officer or director has any substantial interest, direct or indirect, by security holdings or otherwise, in Proposals 5 or 6 that is not shared by all other stockholders.

32

PROPOSAL 5: APPROVAL OF A REVERSE STOCK SPLIT

Our stockholders are being asked to approve an amendment to our Certificate of Incorporation to effect a reverse stock split of our common stock at a reverse stock split ratio ranging from 10:1 to 20:1, inclusive.

Reasons for a Reverse Stock Split

To maintain our listing on the NYSE. As discussed above, the primary purpose of the Reverse Stock Split is to raise the per share trading price of the Company’s common stock in order to maintain its listing on the NYSE. The Board believes that delisting from the NYSE would adversely affect the Company’s ability to raise additional financing through the public or private sale of equity securities, would significantly affect the ability of investors to trade in the Company’s securities, and would negatively affect the value and liquidity of the Company’s common stock. Delisting may also have other negative impacts, including potential loss of employee confidence, the loss of institutional investors, or interest in business development opportunities.

To potentially improve the marketability and liquidity of our common stock. The Board believes that an increased stock price would also improve the marketability and liquidity of our common stock. For example, many brokerages, institutional investors, and funds have internal policies that either prohibit them from investing in low-priced stocks or tend to discourage individual brokers from recommending low-priced stocks to their customers by restricting or limiting the ability to purchase such stocks on margin. Additionally, investors may be dissuaded from purchasing stocks below certain prices because brokers’ commissions, as a percentage of the total transaction value, can be higher for low-priced stocks.

To decrease the risk of market manipulation of our common stock. The Board believes that an increased stock price may reduce the risk of market manipulation of our common stock, which we believe is increased when our stock trades below $1.00 per share. By reducing market manipulation risk, we may also thereby potentially decrease the volatility of our stock price.

To provide us with flexibility with respect to our authorized common stock. A Reverse Stock Split, notwithstanding the potential implementation of an Authorized Shares Reduction, is expected to increase the number of authorized, but unissued and unreserved, shares of our common stock. These additional shares would provide flexibility to the Company for raising capital; repurchasing debt; providing equity incentives to employees, officers, directors, consultants, and advisors (including pursuant to our equity compensation plans); expanding our business through the acquisition of other businesses; and for other purposes. However, we currently do not have any specific plans, arrangements, understandings or commitments for the additional shares that would become available.

Accordingly, for these and other reasons, the Board believes that a Reverse Stock Split is in the best interests of the Company and our stockholders.

Criteria to be Used for Determining Whether to Implement a Reverse Stock Split

Proposal 5 gives the Board discretion to select a Reverse Stock Split ratio from within a range between and including 10:1 and 20:1 based on the Board’s then-current assessment of the factors below, and in order to maximize Company and stockholder interests. In determining whether to implement the Reverse Stock Split, and which ratio to implement, if any, the Board may consider, among other factors:

33

Certain Risks and Potential Disadvantages Associated with a Reverse Stock Split

We cannot assure stockholders that the proposed Reverse Stock Split will sufficiently increase our stock price to regain compliance with the NYSE’s Price Criteria Rule or be completed before the NYSE commences delisting procedures. The effect of a Reverse Stock Split on our stock price cannot be predicted with any certainty, and the history of reverse stock splits for other companies in our industry is varied, particularly since some investors may view a reverse stock split negatively. It is possible that our stock price after a Reverse Stock Split will not increase in the same proportion as the reduction in the number of shares outstanding, causing a reduction in the Company’s overall market capitalization. Furthermore, even if we implement a Reverse Stock Split, our stock price may decline due to various factors, including our future performance and general industry, and market or economic conditions. This percentage decline, as an absolute number and as a percentage of our overall market capitalization, may be greater than would occur in the absence of a Reverse Stock Split. If we continue to fail to meet any of the NYSE’s listing requirements, the NYSE may suspend trading and commence delisting proceedings.

The proposed Reverse Stock Split may decrease the liquidity of our common stock and result in higher transaction costs. The liquidity of our common stock may be negatively affected by the reduced number of shares outstanding after the Reverse Stock Split, which would be exacerbated if the stock price does not increase following the split. In addition, a Reverse Stock Split would increase the number of stockholders owning “odd lots” of fewer than 100 shares, trading in which generally results in higher transaction costs. Accordingly, a Reverse Stock Split may not achieve the desired results of increasing marketability and liquidity as described above.

The implementation of a Reverse Stock Split, even with an Authorized Shares Reduction, would result in an effective increase in the authorized number of shares of common stock available for issuance, which could, under certain circumstances, have anti-takeover implications. The additional shares of common stock available for issuance could be used by the Company to oppose a hostile takeover attempt or to delay or prevent changes in control or in our management. Although the Reverse Stock Split has been prompted by business and financial considerations, and not by the threat of any hostile takeover attempt (nor is the Board currently aware of any such attempts directed at us), stockholders should be aware that approval of the Reverse Stock Split could facilitate future efforts by us to deter or prevent changes in control, including transactions in which stockholders might otherwise receive a premium for their shares over then-current market prices.

Stockholders should also keep in mind that the implementation of a Reverse Stock Split does not have an effect on the actual or intrinsic value of our business or a stockholder’s proportional ownership interest (subject to the treatment of fractional shares). However, should the overall value of our common stock decline after a Reverse Stock Split, then the actual or intrinsic value of shares held by stockholders will also proportionately decrease as a result of the overall decline in value.

Effects of a Reverse Stock Split

As of the Effective Date:

34

The following tables summarize, for illustrative purposes only, the anticipated effects of a Reverse Stock Split on our shares available for issuance based on information as of March 31, 2025 (unless otherwise noted below) and without giving effect to the treatment of fractional shares.

Assuming Both Proposals 5 and 6 Are Approved by Stockholders and Implemented by the Board

Assuming Proposal 5 (but not Proposal 6) Is Approved by Stockholders and Implemented by the Board

35

A Reverse Stock Split would affect all stockholders uniformly. As of the Effective Date, each stockholder would own a reduced number of shares of common stock. Percentage ownership interests, voting rights and other rights and preferences would not be affected, except to the extent that the Reverse Stock Split would result in fractional shares (as described below).

A Reverse Stock Split would not affect the registration of our common stock under Section 12(b) of the Exchange Act, and we would continue to be subject to the periodic reporting and other requirements of the Exchange Act. Barring delisting by the NYSE, our common stock would continue to be listed on the NYSE under the symbol “STEM,” but would have a new Committee on Uniform Securities Identification Procedures (CUSIP) number after the Effective Date.

Cash Payment In Lieu of Fractional Shares

The Company will not issue any fractional shares of common stock as a result of the Reverse Stock Split. In lieu of any fractional shares to which a stockholder of record would otherwise be entitled, the Company will pay cash (without interest and subject to withholding taxes, as applicable) equal to such fraction multiplied by the closing price of our common stock on the NYSE on the first business day immediately preceding the Effective Date (as adjusted in good faith by the Company to account for the Reverse Stock Split ratio). After the Effective Date, a stockholder otherwise entitled to a fractional interest will not have any voting, dividend, or other rights with respect to such fractional interest, except to receive such cash payment.

Additionally, under the escheat laws of the various jurisdictions where stockholders may reside, where the Company is domiciled, or where the cash payment may be deposited, sums due for fractional interests that are not timely claimed after the Effective Date may be required to be paid to the designated agent for such jurisdiction, unless correspondence has been received by us or the transfer agent concerning ownership of such funds within the specified time period. Thereafter, stockholders otherwise entitled to receive such payments would need to seek them directly from the state to which they were paid.

As of March 31, 2025, there were 87 common stockholders of record. After the Effective Date, stockholders owning less than a whole share will no longer be stockholders. We do not intend for this transaction to be the first step in a series of plans or proposals of a “going private transaction” within the meaning of Rule 13e-3 of the Exchange Act.

Procedure for Effecting a Reverse Stock Split

Beneficial holders of common stock. Stockholders who hold their shares through a bank, broker or other nominee will be treated in the same manner as registered stockholders (who hold their shares in their names). Banks, brokers, and other nominees will be instructed to effect the Reverse Stock Split for beneficial owners of such shares. However, banks, brokers or other nominees may implement different procedures than those to be followed by registered stockholders for processing the Reverse Stock Split, particularly with respect to the treatment of fractional shares. Stockholders whose shares of common stock are held in the name of a bank, broker or other nominee are encouraged to contact their bank, broker or other nominee with any questions regarding the procedures for implementing the Reverse Stock Split with respect to their shares.

Registered holders of common stock. Registered stockholders hold shares electronically in book-entry form under the direct registration system (i.e., do not have stock certificates evidencing their share ownership but instead have a statement reflecting the number of shares registered in their accounts) and, as a result, do not need to take any action to receive post-split shares. If they are entitled to receive post-split shares, they will automatically receive, at their address of record, a transaction statement indicating the number of post-split shares held following the Effective Date.

Material U.S. Federal Income Tax Consequences

The following is a summary of material U.S. federal income tax consequences of a Reverse Stock Split to stockholders. This summary is based on the provisions of the Code, U.S. Treasury regulations, administrative rulings, and judicial decisions, all as in effect on the date of this filing, and all of which are subject to change or differing interpretations, possibly with retroactive effect. Any such change or differing interpretation could affect the tax consequences described below.

We have not sought and will not seek an opinion of counsel or ruling from the Internal Revenue Service (the “IRS”) with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS or a court will agree with such statements and conclusions.

This summary is limited to stockholders that are U.S. holders, as defined below, and that hold our common stock as a capital asset (generally, property held for investment).

This summary is for general information only and does not address all U.S. federal income tax considerations that may be applicable to a holder’s particular circumstances or to holders that may be subject to special tax rules, such as, for example, brokers and dealers in securities, currencies, or commodities, banks, and financial institutions, regulated investment companies, real estate investment trusts, expatriates, tax-exempt entities, governmental organizations, traders in securities that elect to use a mark-to-market method of accounting for their securities, certain former citizens or long-term residents of the U.S., insurance companies, persons holding shares of our common stock as part of a hedging, integrated or conversion transaction or a straddle or persons deemed to sell shares of our common stock under the constructive sale provisions of the Code, persons that hold more than 5% of our common stock, persons that hold our common stock in an individual retirement account, 401(k) plan or similar tax-favored account, or partnerships or other pass-through entities for U.S. federal income tax purposes and investors in such entities. This summary does not address any U.S. federal tax consequences other than U.S. federal income tax consequences (such as estate or gift tax consequences), the Medicare tax on net investment income, the alternative minimum tax or any U.S. state, local, or foreign tax consequences. This summary also does not address any U.S. federal income tax considerations relating to any other transaction other than the Reverse Stock Split.

For purposes of this summary, a “U.S. holder” means a beneficial owner of our common stock that is, for U.S. federal income tax purposes:

If an entity (or arrangement) classified as a partnership for U.S. federal income tax purposes holds shares of our common stock, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. If a holder of our common stock is a partner of a partnership holding shares of our common stock, such holder should consult his or her own tax advisor.

This summary of certain U.S. federal income tax consequences is for general information only and is not tax advice. Stockholders are urged to consult their own tax advisor with respect to the application of U.S. federal income tax laws to their particular situation as well as any tax considerations arising under other U.S. federal tax laws (such as the estate or gift tax laws) or under the laws of any state, local, foreign, or other taxing jurisdiction or under any applicable tax treaty.

37

The proposed Reverse Stock Split is intended to be treated as a recapitalization for U.S. federal income tax purposes. Assuming the Reverse Stock Split qualifies as a recapitalization, except as described below with respect to cash received in lieu of a fractional share, a U.S. holder will not recognize any gain or loss for U.S. federal income tax purposes upon the Reverse Stock Split. In the aggregate, a U.S. holder’s tax basis in the common stock received pursuant to the Reverse Stock Split (excluding the portion of the tax basis that is allocable to any fractional share) will equal the U.S. holder’s tax basis in its common stock surrendered in the Reverse Stock Split in exchange therefor, and the holding period of the U.S. holder’s common stock received pursuant to the Reverse Stock Split will include the holding period of the common stock surrendered in the Reverse Stock Split in exchange therefor.

In general, a U.S. holder who receives a cash payment in lieu of a fractional share will recognize capital gain or loss equal to the difference between the amount of cash received in lieu of the fractional share and the portion of the U.S. holder’s tax basis of the common stock surrendered in the Reverse Stock Split that is allocable to the fractional share. Such gain or loss generally will be long-term capital gain or loss if the U.S. holder’s holding period in its common stock surrendered in the Reverse Stock Split is more than one year as of the date of the Reverse Stock Split. The deductibility of net capital losses by individuals and corporations is subject to limitations. Depending on a stockholder’s individual facts and circumstances, it is possible that cash received in lieu of a fractional share could be treated as a distribution under Section 301 of the Code, so stockholders should consult their own tax advisors as to that possibility and the resulting tax consequences to them in that event.

U.S. holders that have acquired different blocks of our common stock at different times or at different prices are urged to consult their own tax advisors regarding the allocation of their aggregated adjusted basis among, and the holding period of, our common stock.

Information returns generally will be required to be filed with the IRS with respect to the payment of cash in lieu of a fractional share made pursuant to the Reverse Stock Split unless such U.S. holder is an exempt recipient and timely and properly establishes with the applicable withholding agent the exemption. In addition, payments of cash in lieu of a fractional share made pursuant to the Reverse Stock Split may, under certain circumstances, be subject to backup withholding, unless a U.S. holder timely provides to the applicable withholding agent proof of an applicable exemption or a correct taxpayer identification number, and otherwise complies with the applicable requirements of the backup withholding rules. Any amounts withheld under the backup withholding rules are not additional tax and may be refunded or credited against the U.S. holder’s U.S. federal income tax liability, provided that the U.S. holder timely furnishes the required information to the IRS. U.S. holders should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption.

Accounting Consequences

The par value per share of our common stock will remain unchanged at $0.0001 per share following a Reverse Stock Split. As a result, as of the Effective Date, the stated capital on the Company’s balance sheets attributable to common stock will be reduced proportionally based on the Reverse Stock Split ratio, and the additional paid-in capital will be credited with the amount by which the capital is reduced. The net income or loss per share of common stock will be increased as a result of the fewer shares of common stock outstanding. The Reverse Stock Split will be reflected retroactively in our consolidated financial statements.

Required Vote

The affirmative vote of a majority of the votes cast is required for the approval of the Reverse Stock Split. Abstentions and broker non-votes, if any, will have no effect on the outcome of this proposal.

Recommendation of the Board

The Board recommends that you vote “FOR” the approval of the Reverse Stock Split.

38

PROPOSAL 6: APPROVAL OF A REDUCTION IN THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK

In connection with the Reverse Stock Split, our stockholders also are being asked to approve an amendment to our Certificate of Incorporation to effect, at certain ratios, a reduction in the total number of authorized shares of our common stock, as illustrated in the table under the caption “Relationship Between the Reverse Stock Split Ratio and the Authorized Shares Reduction.” The implementation of the Authorized Shares Reduction is contingent upon the implementation of the Reverse Stock Split.

Reasons for an Authorized Shares Reduction; Certain Risks

The implementation of a Reverse Stock Split does not require a reduction in the number of authorized shares. As described above, in the event a Reverse Stock Split is implemented, the Board desires to ensure that it strikes an appropriate balance in the post-split number of authorized but unissued and unreserved shares. In determining the appropriate reduction in authorized shares described below, the Board sought to balance relevant proxy advisory firm guidelines with the need to maintain sufficient flexibility with respect to our authorized common stock (as described in more detail above).

The Authorized Shares Reduction would not be directly proportionate to the Reverse Stock Split ratio, and, at a ratio of 10:1 there would be no Authorized Share Reduction, which means, in the event a Reverse Stock Split is implemented, there would be an effective increase in the number of authorized shares of common stock available for issuance. However, this increase would be smaller than the effect a Reverse Stock Split would have had without an Authorized Shares Reduction.

As described in Proposal 5, a Reverse Stock Split and the resulting effective increase in the number of authorized shares available for issuance could, under certain circumstances, have anti-takeover implications. Stockholders should be aware that if Proposal 5 is approved and Proposal 6 is not approved, the authorized shares of common stock would remain unchanged at 500 million shares, and as such, the anti-takeover implications associated with any Reverse Stock Split may be enhanced.

Effects of an Authorized Shares Reduction

If Proposals 5 and 6 are approved, and the Reverse Stock Split is implemented at certain ratios, the Authorized Shares Reduction will become effective simultaneously with the Reverse Stock Split on the Effective Date. As of the Effective Date, the number of authorized shares of common stock will automatically be reduced from 500 million to a range between 250 million and 333 million, as detailed below. For more information, see the caption “Effects of a Reverse Stock Split.”

Relationship Between the Reverse Stock Split Ratio and the Authorized Shares Reduction

The Authorized Shares Reduction will not have any effect on the rights of existing stockholders or the par value per share of the common stock.

39

Required Vote

The affirmative vote of a majority of the votes cast is required for the approval of the Authorized Shares Reduction. Abstentions and broker non-votes, if any, will have no effect on the outcome of this proposal.

Recommendation of the Board

The Board recommends that you vote “FOR” the approval of the Authorized Shares Reduction.

PROPOSAL 7: APPROVAL OF THE ADJOURNMENT OF THE ANNUAL MEETING, IF NECESSARY OR APPROPRIATE, TO SOLICIT ADDITIONAL PROXIES

General

We may ask stockholders to vote on a proposal to adjourn the Annual Meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the Annual Meeting to adopt any of the other proposals. In that event, stockholders will be asked to vote only upon this proposal and not on any other matter. If this proposal is approved, the Board may in its discretion, if necessary or appropriate, adjourn the Annual Meeting to use the additional time to solicit additional proxies in favor of any of the other proposals. Even if there are a sufficient number of votes at the time of the Annual Meeting to adopt one of the other proposals, the Board may in its discretion seek to, if necessary or appropriate, adjourn the Annual Meeting to solicit additional proxies for the proposal for which there are insufficient votes, and the Board may do so without adopting the proposal for which there are sufficient votes at the time of the Annual Meeting.

Required Vote

The affirmative vote of a majority of shares of common stock present or represented at the Annual Meeting and entitled to vote thereon is required for the approval of the adjournment of the Annual Meeting. Abstentions will have the same effect as a vote “against” this proposal. Broker non-votes, if any, will have no effect on the outcome of this proposal.

Recommendation of the Board

The Board recommends that you vote “FOR” the approval of the adjournment of the Annual Meeting.

REPORT OF THE AUDIT COMMITTEE

During 2024, only non-management directors comprised the Audit Committee. The Board determined that each member of the Audit Committee is independent under the NYSE listing standards. The Audit Committee operates under a written charter adopted by the Board. As described more fully in its charter, the purpose of the Audit Committee is to assist the Board in its general oversight of the Company’s accounting and financial reporting processes, audits of the financial statements, internal control and audit functions, and compliance with legal and regulatory requirements and ethical standards adopted by the Company.

The Audit Committee has reviewed and discussed the audited financial statements for the year ended December 31, 2024 with the Company’s management and with Deloitte, the Company’s independent registered public accounting firm. The Audit Committee has discussed with Deloitte the matters required to be discussed by the applicable standards of the PCAOB and the SEC. The Audit Committee has also received the written disclosures and the letter from Deloitte pursuant to applicable PCAOB requirements regarding its communications with the Audit Committee concerning independence, and the Audit Committee has discussed with Deloitte its independence.

Based on the foregoing, the Audit Committee recommended to the Board, and the Board approved, the inclusion of the audited financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

CORPORATE GOVERNANCE

Our current governance practices provide for strong independent leadership, active participation by independent directors, and independent evaluation of, and communication with, many members of senior management. These governance practices are reflected in our Corporate Governance Guidelines and our various committee charters, which are available on our website located at investors.stem.com, under “Governance.”

Our Governance Philosophy

Our Board believes that there is no single set of generally accepted corporate governance practices that is appropriate across all companies, and that governance practices may evolve as circumstances change. In 2021, our Board determined to separate the CEO and Chairman of the Board functions to allow our independent Chairman to oversee corporate governance matters and our CEO to focus on leading the Company’s business. See “—Board Leadership Structure” below for more information.

Our history as a special purpose acquisition company prior to the Merger left us with certain structural protections. For example, we currently have a classified Board and plurality voting for the election of directors, only the Board is empowered to call a special meeting of our stockholders, and we require a supermajority vote for stockholders to approve amendments to our Bylaws and a limited number of items in our Certificate of Incorporation. Following careful deliberation after the closing of the Merger, our Board initially determined to retain these measures for a period to promote stability and continuity of our Board and to allow us to focus on a consistent strategy while we established ourselves as a public company and transition away from our SPAC roots.

The Board assesses our corporate governance practices at least annually, and may modify these practices from time to time to best address the Company’s unique circumstances, and respond to feedback from and advance the best interests of all stockholders, as and when it believes appropriate.

In 2023, our Board approved, subject to stockholder approval, amendments to our Certificate of Incorporation to:

At our 2023 Annual Meeting of Stockholders, we submitted proposals to declassify our Board and remove the supermajority vote requirement. While both proposals received strong support (with over 98% of the votes cast in favor of such proposals), the proposals did not receive the requisite number of votes as a percentage of our shares outstanding in order to pass. We currently intend to resubmit such proposals at the 2026 Annual Meeting of Stockholders.

Board Composition

Director Nomination Process

The Nominating Committee is responsible for, among other things, overseeing succession planning for directors and building a qualified board to oversee management’s execution of the Company’s strategy and safeguard the long-term interests of stockholders. In this regard, the Committee is charged with developing and recommending Board membership criteria to the Board for approval, evaluating the composition of the Board annually to assess the skills and experiences that are currently represented on the Board and the skills and experiences that the Board may find valuable in the future, and identifying, evaluating, and recommending potential director candidates.

43

In identifying potential candidates for Board membership, the Nominating Committee considers recommendations from directors, stockholders, management, and others, including, from time to time, third-party search firms to assist it in locating qualified candidates. Once potential director candidates are identified, the Committee, with the assistance of senior executive management, undertakes a vetting process that considers each candidate’s background, independence, and fit with the Board’s priorities. As part of this vetting process, the Nominating Committee, as well as other members of the Board and the CEO, conduct interviews with the candidates. If the Committee determines that a potential candidate meets the needs of the Board and has the desired qualifications, it recommends the candidate to the Board for appointment or nomination and to the stockholders for election at the annual meeting. In the case of Mr. Shivram, a member of management identified him as a potential candidate for Board membership. In the case of Mr. Guruswamy, our CEO identified him as a potential candidate for Board membership.

Criteria for Board Membership

In assessing potential candidates for Board membership and in assessing Board composition, the Nominating Committee considers a wide range of factors and generally seeks to balance the following skills, experiences, and backgrounds on the Board:

In addition to the above, the Nominating Committee generally believes it is important for all Board members to possess the highest personal and professional ethics, integrity, and values, an inquisitive and objective perspective, a sense for priorities and balance, the ability and willingness to devote sufficient time and attention to Board matters, and a willingness to represent the long-term interests of all our stockholders.

The Nominating Committee assesses its effectiveness in balancing these considerations in connection with its annual evaluation of the composition of the Board.

Summary of Director Skills and Characteristics

The chart below summarizes the qualifications of our directors, as well as director nominees, including knowledge, skills, experiences, and other attributes that the Board believes are relevant to their Board and committee service. Not having a mark does not mean the director does not possess that qualification, skill, or experience. Each director and nominee possesses numerous other skills and experience not identified in the following chart, as further detailed in their biographies beginning on or around page 7 of this Proxy Statement. We believe our directors, including our director nominees, provide a well-rounded set of expertise to assist in effective oversight of Stem management.

45

Stockholder Recommendations for Directors

It is the Nominating Committee’s policy to consider written recommendations from stockholders for nominees for director. The Committee considers nominees recommended by our stockholders in the same manner as a candidate recommended by other sources. Any such recommendations should be submitted to the Committee as described in the section titled “Communications with the Board” and should include the same information required under our Bylaws for nominating a director, as described under “Stockholder Proposals and Director Nominations for Next Year’s Annual Meeting.”

Board Leadership Structure

One of the Board’s key responsibilities is to evaluate and determine an appropriate board leadership structure to provide for independent oversight of management. As stated above, the Board believes that there is no single, generally accepted board leadership structure that is appropriate across all circumstances, and that the right structure may vary as circumstances change. As such, the independent members of the Board periodically review the Board’s leadership structure to evaluate whether the structure remains appropriate for the Company, and may modify this structure from time to time to best address the Company’s unique circumstances and advance the best interests of all stockholders, as and when appropriate. At any time when the chairman is not independent or there is not a chairman, the independent members of the Board will, upon the recommendation of the Nominating Committee, designate an independent director to serve as lead independent director.

Our Board’s independent directors have selected an independent member of the Board, David Buzby, to serve as Chairman of the Board. The Board recognizes that one of its key responsibilities is to evaluate and determine an appropriate board leadership structure so as to promote independent oversight of management. Currently, the Board believes that the roles of Chairman and CEO should be separate and that the Chairman should be an independent director as this structure enables our independent Chairman to oversee corporate governance matters and our CEO to focus on leading the Company’s business. Previously, during the Company’s leadership transition, the Board appointed Mr. Buzby to serve in the combined role of Interim CEO and Executive Chairman of the Board, and appointed Dr. Tyson to serve as Lead Independent Director, in order to provide unified leadership while the Company recruited a new CEO.

Our Board believes that its programs for overseeing risk, as described in the “Board Risk Oversight” section below, would be effective under a variety of leadership frameworks. Accordingly, the Board’s risk oversight function did not significantly affect its selection of the current leadership structure.

The independent directors generally meet in executive session without management present at every regular Board meeting. The purpose of these executive sessions, which are led by our independent Chairman of the Board, is to encourage and enhance communication among independent directors.

Board Oversight of Risk Management

The Board and its committees are actively involved in overseeing risk management for Stem. The Board routinely assesses the Company’s major risks and options for mitigation, in order to promote our stockholders’ interests in Stem’s long-term health, financial strength, and overall success. We believe that our Board composition provides the Company with robust and well-rounded experience to assist in effective oversight of management, as discussed on or around page 43 of this Proxy Statement. The full Board oversees assessment of major risks facing the Company, determining the extent to which such risks are applicable and, to the extent the Board deems it appropriate, evaluating management’s plans for their mitigation. The risks that the Board routinely considers broadly relate to strategic, operational, financial, regulatory, competitive and geopolitical risks. The full Board oversees risk management by the CEO and the rest of our senior management team, by reviewing major financial objectives and critical strategies and long-term plans, including, but not limited to, major allocations of capital, operating performance, and sustainability.

46

In addition, the Board delegates to its committees responsibility for overseeing certain types of risk, some of which are reflected below:

The Board committees report regularly to the Board on activities in their respective areas of oversight. In addition, the Board and its committees receive regular reports from members of the Company’s senior management on areas of significant risk to the Company, including strategic, operational, financial, legal and regulatory risks. While our Board has an oversight role, management is tasked with direct day-to-day responsibility for management and assessment of risks and the implementation of processes and controls to mitigate their effects on the Company.

Our senior management team has developed a comprehensive strategic planning and enterprise risk management (“ERM”) process for identifying, assessing and managing risk. Through this process, we identify key risks through a quarterly corporate-level risk mapping exercise, which involves the CEO, CFO, CLO, and other members of senior management, along with a bottom-up operational risk assessment by our various business units and functions. Our executive leadership team and its ERM and Disclosure Committee report directly to the Board, and on a quarterly basis, present to the Board a comprehensive report on material risk identification, response, and mitigation strategies. In addition, we have a DevCo Investment and Risk Committee (the “DevCo Committee”) comprised of our CEO, CFO, CLO, COO, and other members of senior management in sales, finance, and operations. The purpose of the DevCo Committee in 2024 was to report on, and manage, our development company (“DevCo”) strategy and operations, as well to identify and manage major risks as relate to our DevCo business model and parent company guarantees (“PCGs”). In 2024, the DevCo IC met at least monthly and reported quarterly to the Audit Committee on areas of DevCo and PCG activity and risks, as well as mitigants. In mid-2024, our Executive Chair and the Chair of our Audit Committee joined these meetings in oversight roles.

Director Independence

The NYSE listing rules require a majority of a listed company’s board of directors to be comprised of independent directors who do not have a disqualifying relationship, as described in the NYSE listing rules, and who, in the opinion of the board of directors, have no direct or indirect material relationship with the company. Subject to specified exceptions, each member of a listed company’s audit, compensation, and nominating committees must be independent, and audit and compensation committee members must satisfy additional independence criteria under the NYSE listing rules and the Exchange Act.

Our Board undertook a review of its composition and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment, and affiliations, including the beneficial ownership of our capital stock by each non-employee director, our Board has determined that all of our current directors, including Messrs. Buzby, Birns, Daley, Guruswamy, Shivram, and Tammineedi and Dr. Tyson, qualify as “independent directors” as defined by the NYSE listing rules. Mr. Buzby was not independent while he served as Interim CEO and Executive Chair of the Company in connection with the leadership transition, but, in accordance with NYSE listing rules, resumed his status as an independent director following such service. Former director John Carrington was not independent during the period he

47

served on the Board, due to his employment with the Company. Former director Gerard Cunningham was not independent during the period he served on the Board due to the compensation received for his former service on the Company’s Software Strategy Working Group. Former directors Michael C. Morgan and Jane Woodward were independent during the period they served on the Board.

Our Board also determined that each of the directors currently serving on the Audit Committee and the Compensation Committee satisfy the independence standards for audit committees and compensation committees, as applicable, established by the SEC and NYSE listing rules.

Director Meeting Attendance

In 2024, all of our directors attended at least 75% of the total number of meetings of the Board and its committees on which they served, and all of our directors (except for one) attended 95% of the Board and its committees on which they served. Meetings of the Board and its committees were held in 2024 as follows:

At each 2024 Board meeting, the Board’s independent Chair, or lead independent director, as applicable, led one or more executive session(s) of non-employee directors. In addition, Stem officers regularly attend Board meetings to present information on our business and strategy, and directors have access to our employees outside of Board meetings. From time to time between meetings, Board and committee members confer with each other, with management, and with independent consultants, and representatives of management may meet with these consultants on behalf of the relevant committee.

The Board’s policy is that directors should endeavor to attend the annual meeting of stockholders. Three of our directors then-serving attended our 2024 Annual Meeting of Stockholders.

Board Committees

Our Board has a separately designated Audit, Compensation, and Nominating Committee, each of which has the composition and responsibilities described below. Members serve on these committees until their resignation or until otherwise determined by our Board. Each of these committees is empowered to retain outside advisors as it deems appropriate, regularly reports its activities to the full Board and has a written charter, which is posted on our website located at investors.stem.com, under “Governance.”

48

Audit Committee. The primary responsibilities of our Audit Committee are to oversee the accounting and financial reporting processes of the Company and its subsidiaries, including the audits of the Company’s financial statements, the integrity of the financial statements, and the annual review of the performance, effectiveness, and independence of the outside auditor; and the periodic review of our key sustainability policies and disclosures, and the adequacy and effectiveness of applicable internal reporting and controls related to such disclosures. This includes reviewing the financial information provided to stockholders and others, and reviewing the adequacy and effectiveness of the Company’s internal controls. The Committee also makes recommendations to the Board as to whether our financial statements should be included in our Annual Report on Form 10-K.

The Board has determined that Mr. Birns qualifies as an “audit committee financial expert” under SEC rules, and that each Audit Committee member is sufficiently proficient in reading and understanding the Company’s financial statements to serve on the Audit Committee.

Compensation Committee. The primary responsibilities of our Compensation Committee are to periodically review, evaluate, and approve the total direct compensation and other benefits for our executive officers and directors, and to evaluate whether each element remains competitive with the companies in our executive compensation peer group. This includes reviewing and approving corporate goals and objectives relevant to the compensation of our executive officers, evaluating the performance of these officers in light of the goals and objectives, and setting the officers’ total direct compensation based on those evaluations (except for the total direct compensation of the CEO, which is determined by the independent members of the Board on recommendation of the Compensation Committee). The Compensation Committee oversees our engagement with stockholders on executive compensation matters and also oversees how we manage our human capital resources. The Compensation Committee also administers and makes recommendations to the Board regarding equity incentive plans and approves the grant of equity awards under the plans. The Compensation Committee may delegate its authority to one or more subcommittees or to one member of the Committee.

The Compensation Committee may also delegate authority to review and approve the compensation of our employees to certain of our executive officers. Even where the Compensation Committee does not delegate authority, our executive officers will typically make recommendations to the Compensation Committee regarding compensation to be paid to our employees and the size of equity awards under our equity incentive plans, but will not be present during voting or deliberations on their own compensation. The Compensation Committee has the authority to engage outside advisors, such as compensation consultants, to assist it in carrying out its responsibilities. The Committee engaged Frederic W. Cook & Co., Inc. as its independent compensation consultant in 2024 to provide advice regarding the amount and form of executive and director compensation.

Compensation Committee Interlocks and Insider Participation. None of the members of our Compensation Committee has at any time during the prior three years been one of our officers or employees. None of our executive officers currently serves, or in the past fiscal year has served, as a member of the board of directors or the compensation committee of any entity that has one or more executive officers serving on our Board or Compensation Committee.

Nominating Committee. The primary responsibilities of our Nominating Committee are to engage in succession planning for the Board, develop and recommend to the Board criteria for identifying and evaluating qualified director candidates, and make recommendations to the Board regarding candidates for election or re-election to the Board at each annual meeting of stockholders. The Committee is responsible for overseeing our corporate governance practices and making recommendations to the Board concerning corporate governance matters. The Committee is also responsible for making recommendations to the Board concerning the size, structure, composition, and functioning of the Board and its committees. In addition, the Committee is responsible for overseeing our sustainability policies, activities, and opportunities, our political contributions and lobbying activities, if any, and our engagement with stockholders on governance, sustainability, and related matters.

49

Our Commitment to Sustainability

We are committed to the health and well-being of our people, our communities, and our planet. As we mature as a public company, we intend to continue to formalize our sustainability function and programs by developing our processes, strategies, and governance frameworks. Our Sustainability Policy Statement is available on our website and outlines our philosophy with respect to climate change, greenhouse gas emissions (“GHG”), and supply chain concerns, among other things.

Sustainability Management and Oversight

Our sustainability governance structure is evolving to include numerous participants engaging in information-sharing and decision-making, capitalizing on the depth and breadth of expertise throughout Stem. As discussed in “—Board Committees” above, our Nominating Committee has direct oversight over sustainability issues and regularly meets with key stakeholders to oversee the development of our sustainability program. Our Audit Committee also periodically reviews our key sustainability disclosures and the adequacy and effectiveness of applicable internal reporting and controls related to such disclosures. Our management-level sustainability committee, which is comprised of senior executives and other key stakeholders from our legal, investor relations, and operations functions, provides functional oversight for various sustainability activities at the Company.

Our director of sustainability is in charge of developing our sustainability program. His responsibilities include:

Sustainability Partnerships and Reporting

We have engaged a third-party firm to help us develop our supply chain due diligence program, including with respect to conflict minerals and human rights issues. Our aim is to promote sustainability at all points in our supply chain, and comprehensive due diligence is step one. As we establish and grow these programs, our goal is to have a positive influence, by being open and transparent in our communication and education, with all our partners with whom we engage. Our goal is to develop sustainable relationships with our partners while being guided by the circular economy principle, a model of production and consumption that favors durability, reuse, remanufacturing, and recycling to keep materials circulating for as long as possible and reduce waste. Our Partner Code of Conduct and Human Rights Policy Statement can be found on our website and set out our philosophy with respect to our relationship with our partners and human rights concerns.

In 2024, we continued to work with our carbon accounting partner to assist with tracking our GHG emissions in alignment with the GHG Protocol. In addition, we continued to work with our sustainability partner to assist us with climate and sustainability reporting in alignment with the Task Force on Climate-Related Financial Disclosures (TCFD) and the Sustainability Accounting Standards Board (SASB) frameworks. We are closely following the global consolidation of various climate and sustainability disclosure frameworks, and we intend to align our disclosures in a manner that promotes transparency and accountability.

We expect to publish our annual Sustainability Report later this year, which will be made available publicly on our website. We expect to discuss, among other things, our carbon footprint and how we intend to continue to support global decarbonization to reduce the impact of climate change.

Valuing Inclusion

We are committed to building an inclusive culture and team environment that promotes equal employment opportunities and supports our talent. In the spirit of our core values, we are “One Team” and succeed through collaboration when we respect, acknowledge, and celebrate each other’s varied perspectives. We are committed to creating an environment that promotes inclusivity and respect by implementing policies, benefits, training, recruiting, and recognition practices to support our colleagues.

We believe that helping all our employees realize their highest potential by fostering a culture that supports personal development across the organization is necessary to promote inclusion. Our employees have opportunities to learn new skills to develop and advance their careers, and we provide opportunities for all our employees to receive ongoing formal training to help foster their professional development.

We also value the feedback we receive from our employees. In 2023, we launched “Your Voice,” a quarterly employee sentiment portal, which is designed to facilitate communication with our employees and enhance our understanding of employee feedback. In addition, our annual employee engagement survey asks all our employees for their input on a variety of matters. The results of the employee survey are disseminated to all employees, and the results are used to design action plans to assist managers with actively responding to employees’ sentiments. We believe that the employee survey is an important tool that allows us to improve, innovate, and evolve through ongoing engagement and measurement.

Other Corporate Governance Practices and Policies

Board Evaluation Process

In addition to regularly reviewing its leadership structure, the Board conducts an annual self-assessment of its overall functioning and effectiveness. In order to maximize input and facilitate useful feedback, our Secretary solicits from each director, on an anonymous basis, comments on overall Board and committee performance, Board priorities, interaction with management, the flow of information from management to and from the Board and its committees, Board discussion topics, agendas, and processes, and how to further improve overall Board functioning. This information is collected through written questionnaires and assessments, and individual director interviews. In addition, the Chairman of the Board makes himself available for one-on-one discussions with the other members of the Board. Our Secretary then aggregates and anonymizes the responses, which he then shares with the Nominating Committee. The Chair of the Nominating Committee, along with our Secretary, reviews the feedback from the self-evaluation process and makes recommendations to the Board for areas with respect to which the Board and its committees should consider improvements. These areas are further discussed at a meeting led by our Secretary, at which all Board members are present. At the conclusion of this meeting, the Chairman of the Board, working with the senior management team, develops action plans for any items that require follow-up. For example, in 2024, directors continued to prioritize the need for meeting discussions that allowed the Board to discuss and interact efficiently with management on key topics relating to long-term strategy, capital allocation, cost structure, risk management, and other matters relevant to the business in the dynamic external environment. Similarly, the Board made, and planned for, ongoing adjustments and improvements to its Board and committee meetings in connection with its new strategy and business needs and to help promote efficient and effective interaction and performance of its critical governance and risk oversight roles.

Communications with the Board

Our Board has established a process whereby interested parties may communicate with our Board or with any individual director. Interested parties, including stockholders, may send communications in writing addressed to the Board or an individual director, at [email protected], with a confirmation copy sent by mail to Stem, Inc., c/o the Corporate Secretary, 4 Embarcadero Center, Suite 710, San Francisco, California 94111. Our Corporate Secretary will forward these communications as appropriate to the addressee,

51

depending on the facts and circumstances outlined in the communication. Our Board has directed our Corporate Secretary not to forward certain items such as spam, junk mailings, product inquiries, resumes, and other forms of job inquiries, surveys, and business solicitations. Additionally, our Board has advised the Corporate Secretary not to forward material that is illegal or threatening, but to make our Board aware of such material which it may request be forwarded, retained, or destroyed at our Board’s discretion.

To enable the Company to speak with a single voice, as a general matter, senior management serves as the primary spokesperson for the Company and is responsible for communicating with various constituencies, including stockholders, on behalf of the Company. Directors may participate in discussions with stockholders and other constituencies on issues where Board-level involvement is appropriate. In addition, the Board is kept informed by Company management of the Company’s stockholder engagement efforts.

Code of Business Conduct and Ethics

Our Board has adopted a Code of Business Conduct and Ethics that establishes the standards of ethical conduct applicable to all our directors, officers, and employees, including our principal executive officer, principal financial officer, principal accounting officer, or persons performing similar functions. It addresses, among other matters, compliance with laws and policies, conflicts of interest, corporate opportunities, regulatory reporting, external communications, confidentiality requirements, insider trading, proper use of assets, and how to report compliance concerns. A copy of the code is available on our website located at investors.stem.com, under “Governance.” We intend to disclose future amendments to certain provisions of the code, or waivers of the code granted to executive officers and directors, on our website to the extent required by applicable rules. Our Board is responsible for applying and interpreting the code in situations where questions are presented to it.

EXECUTIVE COMPENSATION

Our NEOs for 2024 are:

Summary Compensation Table

The following table sets forth information concerning the compensation paid to our NEOs:

55

Narrative to Summary Compensation Table

Elements of 2024 Total Direct Compensation

Our 2024 executive compensation program consisted of three primary elements, comprising our NEOs’ total direct compensation:

The chart below sets out the primary elements of our NEOs’ 2024 total direct compensation, certain key features of each element, and how each of these compensation elements supports our strategy.

56

These elements allow the Company to remain competitive and attract, retain and motivate top executive talent with current and potential future financial rewards.

The Compensation Committee reviews the elements of total direct compensation for the NEOs at least annually to evaluate whether each element of direct compensation remains competitive with that of companies in our peer group. The Compensation Committee relies on its own judgment in making these compensation decisions after its review of external market practices of companies in our executive compensation peer group, including the size and mix of direct compensation for executives in those companies. The Compensation Committee seeks to achieve an appropriate balance between annual cash rewards that encourage achievement of annual financial and non-financial objectives, and LTI awards that encourage positive long-term stock price performance, with a greater emphasis on LTI awards for more senior executives.

While external market data provides important guidance in making decisions on executive compensation, the Compensation Committee does not set compensation based on market data alone. When determining the size and mix of each element of an NEO’s target total direct compensation, the Compensation Committee also considers the following factors:

Base Salary

Base salary is the fixed portion of an executive’s annual compensation. The Compensation Committee typically reviews base salaries on an annual basis, referring to market data to understand the marketplace for individuals in similar positions. The Committee does not use a formulaic approach when setting an executive officer’s base salary. Instead, taking into account the recommendations of our CEO (except for his own compensation), the Compensation Committee considers the following factors when determining (or, in the case of the CEO, recommending to the Board) individual base salary levels:

57

Base Salary Decisions in 2024

In February 2024, our Compensation Committee reviewed the base salaries of our NEOs, other than David Buzby and Doran Hole, who were hired later in the year. Applying the factors above, the Committee increased the annual base salary of Mr. Carrington from $550,000 to $600,000, and that of Mr. Carlson from $400,000 to $425,000. Mr. Hole’s base salary was set at $475,000 upon hire, effective September 2024.

Annual Cash Incentive Awards

Our executives are eligible to earn performance-based annual cash incentive awards, based 100% on the achievement of rigorous quantitative financial and operational metrics that are directly linked to the Company’s business strategy. The purpose of our 2024 Annual Incentive Plan (the “2024 AIP”) is to foster a results-driven, pay-for-performance culture and to align executives’ interests with those of our stockholders. Our Compensation Committee selects financial and performance objectives that it believes support our strategy and strike a balance between motivating our executives to increase near-term financial and operating results while driving profitable long-term Company growth and value for stockholders.

The performance metrics under the 2024 AIP were adjusted EBITDA, contracted annual recurring revenue (“CARR”), revenue and operating cash flow.

The Compensation Committee considered the following in selecting these metrics:

Three of the four metrics — adjusted EBITDA, revenue and CARR —were also used in our 2023 Annual Incentive Plan (the “2023 AIP”), with the same relative weightings as in 2023. The Committee approved the addition of operating cash flow as a new metric for 2024 to better align with management’s goal of cash generation.

When considering the Company’s operating results for purposes of the annual cash incentive, the Compensation Committee may take into account unusual or infrequent charges or gains, depending on the nature of the item. The Compensation Committee exercises this discretion when it believes that our executives would inappropriately benefit from, or would be inappropriately penalized by, such items.

58

Annual Cash Incentive Decisions for 2024

Upon review of market data of the applicable compensation peer group, and taking into consideration internal pay equity, the Compensation Committee determined in February 2024 to set Mr. Carrington’s and Mr. Carlson’s 2024 target bonus opportunities at 125% and 75% of salary, respectively. Mr. Hole’s target bonus opportunity was set at 75% of salary upon hire in September 2024, which was to be pro-rated for his partial year of service.

2024 AIP Results

Because we did not achieve threshold performance for any approved metric under the 2024 AIP, our NEOs earned no annual cash incentive award for 2024 performance.

Long-Term Equity Incentive Awards

When determining the amount of LTI awards granted to an NEO, the Compensation Committee considers the executive’s experience, level of responsibilities, and contributions to the success of the Company, as well as market data and internal pay equity. In addition to rewarding our NEOs based on personal and Company performance, equity awards have also served to retain the services of such executives since they are subject to time-based vesting conditions.

Our first-quarter 2024 annual LTI awards to Mr. Carrington and Mr. Carlson, who were employed by the Company at such time, consisted of stock options and RSUs. In February 2024, the Committee approved a change in the LTI mix to officers so that 75% of the target LTI award would be in the form of RSUs and 25% would be in the form of stock options, from the previous 50/50 split. However, only Mr. Carlson received this mix for 2024, as he was the only NEO to serve a full year. Mr. Buzby and Mr. Hole were appointed mid-year and received a different split due to sign-on grants, and Mr. Carrington’s award was structured separately. The Committee determined that this was needed to manage our equity share burn rate (because RSUs require less equity burn to provide similar value) and to incentivize and retain our NEOs during a challenging period for our business. The Committee also deemed the change in grant mix to be appropriate because our 2024 NEO grant values were significantly reduced compared to 2023 grant values.

The Compensation Committee approved the LTI awards set forth below to Mr. Carrington and Mr. Carlson in February 2024. In approving these awards, the Committee considered numerous factors, including the severe share constraint in the Company’s equity incentive plan due to, among other things, the significant decline in our common stock price year-over-year; the Committee’s desire to keep the “burn rate” to an acceptable minimum level; market data; internal pay equity, and the need to balance the appropriate size and mix of awards to incentivize and retain executives. Given these factors, the Committee determined to significantly decrease the 2024 equity award grant values compared to 2023 grant values.

Our equity awards to David Buzby and Doran Hole were determined at the time of their commencement of employment and are described in the “Employment Agreements” section below.

Except as described below, stock options were granted on February 15, 2024, with an exercise price of $3.37, and vest in three annual installments, and RSUs were awarded as of May 28, 2024, and vest in three annual installments.

Two NEOs who were appointed mid-year received sign-on LTI grants:

Additionally, on November 1, 2024, the Committee approved an additional award to Mr. Carlson of 275,000 RSUs with a grant date fair value of $110,000, which will vest in full on November 7, 2025, subject to his continued employment at the time of vest; this award was granted outside of the regular 2024 equity compensation program in order to compensate him for the increased uncertainty resulting from our leadership transition and to further incentivize performance for our turnaround in the face of business challenges.

Potential Payments Upon Termination or Change in Control

Each of Messrs. Buzby, Hole and Carlson is party to an employment agreement (each, an “Employment Agreement”) that provides for certain severance payments and benefits in connection with certain qualifying terminations of employment, as well as enhanced severance payments and benefits if qualifying terminations of employment occur in connection with a “Change in Control” (as defined in the Company’s 2024 Equity Incentive Plan).

Employment Agreements

David Buzby: We entered into an executive employment agreement with Mr. Buzby in connection with his appointment as Interim CEO and Executive Chair. Under the Agreement, Mr. Buzby received an annualized base salary of $600,000, less applicable taxes, payroll deductions and withholdings, prorated for the total duration of his service in 2024. In connection with his service, he also received (a) a cash incentive award under the Company’s annual incentive plan with a target bonus opportunity of 125% of his annual base salary, subject to the Company’s performance and a guaranteed minimum payout of 75% of the target bonus opportunity, which was prorated for the total duration of his service in 2024, and (b) a grant of 400,000 stock options, with an exercise price of $1.00, vesting ratably for six months. Mr. Buzby was also entitled to reimbursement of temporary housing expenses not to exceed $6,700 per month and reasonable travel and transportation expenses. Mr. Buzby served as Interim CEO and Executive Chair until the Board appointed Mr. Arun Narayanan as the Company’s CEO on January 27, 2025; Mr. Buzby now serves the Company as the Non-Executive Chair of the Board and is no longer entitled to the compensation and benefits described above.

Doran Hole: In connection with his appointment as CFO and EVP, we entered into an executive employment agreement with Mr. Hole. Under the agreement, Mr. Hole receives an annual base salary of $475,000, less applicable taxes, payroll deductions and withholdings. In connection with his appointment, he also

received: (a) a sign-on cash bonus of $300,000, less applicable taxes, payroll deductions and withholdings; (b) a sign-on, make-whole, equity award of RSUs with a target value of $400,000 (to replace forfeited equity at his previous employer), which will vest 100% on November 7, 2025, subject to his continued employment with the Company on such date; (c) an initial long-term incentive equity award with a target value of $1,000,000, in the form of 75% RSUs and 25% stock options, with 33% vesting on November 7, 2025, 33% vesting on November 7, 2026, and 34% vesting on November 7, 2027, subject to his continued employment with the Company through the applicable vesting dates; and (d) reimbursement for reasonable relocation expenses not to exceed $100,000 and reasonable temporary housing expenses not to exceed $25,000, subject to repayment under certain circumstances. In addition, Mr. Hole was eligible to receive a cash incentive award under the Company’s annual incentive plan with a target bonus opportunity of 75% of his annual base salary (to be prorated for his partial year of service in 2024).

Michael Carlson: We entered into an employment agreement with Mr. Carlson in 2022, which provided for his initial compensation and benefits, including an initial base salary, annual bonus opportunity, and initial equity awards. Mr. Carlson’s employment agreement is on the Company’s standard form of Executive Employment Agreement, a copy of which was previously filed with the SEC as Exhibit 10.11 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

Change in Control Benefits

The “Change in Control Period” in Mr. Hole’s and Mr. Carlson’s Employment Agreements commences three months prior to the occurrence of the Change in Control and ends 12 months following the Change in Control. Upon a termination without “Cause” (other than a termination due to death or disability) or resignation for “Good Reason,” in each case, outside of the Change in Control Period (each, as defined in the employment agreements), the NEO would be eligible to receive: (i) payment of any bonus earned, but not yet paid for the year prior to the year of termination; (ii) an amount equal to nine months in the cases of Mr. Hole and Mr. Carlson, of annual base salary in effect immediately prior to termination; (iii) payment of a pro rata bonus for the year of termination based on actual performance; (iv) payment or reimbursement for the premiums that the NEO would be required to pay to maintain continued health coverage under COBRA for a period of up to nine months following the date of termination; and (v) for Mr. Carlson, the accelerated vesting of certain outstanding equity awards. Receipt of all such payments and benefits would be subject to the NEO’s execution and non-revocation of a release of claims and his continued compliance with the covenants set forth in his employment agreement.

Upon a termination without Cause (other than a termination due to death or disability) or resignation for Good Reason, in each case, during the Change in Control Period, the NEO would be eligible to receive: (i) cash payment equal to one times the sum of the NEO’s annual base salary plus target bonus; (ii) payment of any bonus earned, but not yet paid for the year prior to the year of termination; (iii) payment of a pro- rata bonus for the year of termination based on actual performance; and (iv) payment or reimbursement for the premium that the NEO would be required to pay to maintain continued health coverage under COBRA for a period of up to twelve months following the date of termination. Receipt of all such payments and benefits would be subject to the NEO’s execution and non-revocation of a release of claims and his continued compliance with the covenants set forth in the employment agreements.

Carrington Separation Agreement

Mr. Carrington served as a Strategic Advisor until December 31, 2024, at which time his employment with the Company was terminated. In connection with Mr. Carrington’s termination, we entered into a Separation and Release of Claims Agreement with Mr. Carrington. In addition, because Mr. Carrington’s departure constituted a termination without cause, he was entitled to the following payments and benefits pursuant to the terms and applicable provisions of his Employment Agreement, which we entered into with Mr. Carrington in 2021: (i) a cash payment of $600,000, being equal to 12 months of his annual base salary in effect on the Separation Date, less applicable taxes and withholdings; (ii) reimbursement for up to 12 months for 100% of the monthly premium

62

costs of continuation coverage under COBRA; (iii) accelerated vesting of 171,428 RSUs (with all other outstanding and unvested stock options and RSUs being forfeited as of the Separation Date); and (iv) all stock options that were vested as of the Separation Date will remain exercisable until the earlier of (A) the date three months following the Separation Date and (B) the expiration of the term of such stock options as set forth in the applicable award agreement. All of the foregoing are pursuant to the 2021 Employment Agreement and in consideration of Mr. Carrington’s non-revocation of the release of claims in favor of the Company, and his continued compliance with certain confidentiality, non-disparagement, and non-competition covenants.

The 2021 Plan

Pursuant to the terms of the 2021 Equity Incentive Plan, and unless provided otherwise in an award agreement or other agreement between us or an affiliate and the participant, in the event of Change in Control (as defined in the 2021 Plan), our Board will take one or more of the following actions with respect to each outstanding award, contingent upon the closing or completion of the Change in Control:

Our Board need not take the same action or actions with respect to all awards or portions thereof or with respect to all participants and may take different actions with respect to the vested and unvested portions of an award. In the absence of any affirmative determination by our Board at the time of a Change in Control, each outstanding award will be assumed or an equivalent award will be substituted by such successor corporation or a parent or subsidiary of such successor corporation, referred to as a successor corporation, unless the successor corporation does not agree to assume the award or to substitute an equivalent award, in which case the vesting of such award will accelerate in its entirety (along with, if applicable, the time at which the award may be exercised) to a date prior to the effective time of such Change in Control as our Board will determine (or, if our Board does not determine such a date, to the date that is five (5) days prior to the effective date of the Change in Control), with such award terminating if not exercised (if applicable) at or prior to the effective time of the Change in Control, and with such exercise reversed if the Change in Control does not become effective.

63

The 2024 Plan

In the event of a Change in Control (as defined in the 2024 Equity Incentive Plan), the Board will take one or more of the following actions with respect to each outstanding award, contingent upon the closing or completion of the Change in Control:

The Board need not take the same action with respect to all awards or portions thereof or with respect to all participants and may take different actions with respect to the vested and unvested portions of an award.

In the absence of any affirmative determination by the Board at the time of a Change in Control, each outstanding award will be assumed or an equivalent award will be substituted by such successor corporation or a parent or subsidiary thereof, unless such successor corporation does not agree to assume or substitute the award, in which case the vesting of such award will accelerate (along with, if applicable, the time at which the award may be exercised) to a date prior to the effective time of such Change in Control as the Board will determine (or, if the Board will not determine such a date, to the date that is five days prior to the effective date of the Change in Control), with such award terminating if not exercised (if applicable) at or prior to the effective time of the Change in Control, and with such exercise reversed if the Change in Control does not become effective.

An award may be subject to additional acceleration of vesting and exercisability upon or after a Change in Control as may be provided in the award agreement for such award or as may be provided in any other written agreement with the participant, but in the absence of such provision, no such acceleration will occur.

Other Compensation Plans

Health and Welfare Plans and 401(k) Plan. The NEOs are eligible to participate in the Company’s employee benefit plans and programs, including medical and dental benefits, flexible spending accounts, long-term care

64

benefits, and short- and long-term disability and life insurance, to the same extent as the Company’s other full-time employees, subject to the terms and eligibility requirements of those plans. The NEOs also participate in our 401(k) plan, subject to limits imposed by the Internal Revenue Code, to the same extent as the Company’s other full-time employees.

Other Benefits. We do not maintain any defined benefit pension plans or any nonqualified deferred compensation plans.

Limited Perquisites. We provide only limited perquisites to our NEOs. None of our NEOs (other than David Buzby, in his capacity as Interim CEO), received $10,000 or more of perquisites or other personal benefits from the Company in 2024.

Stock Ownership Guidelines

In April 2022, the Compensation Committee adopted Stock Ownership Guidelines that apply to our executive officers and directors. The guidelines are intended to further the Company’s goal of promoting sound corporate governance practices by aligning the financial interests of the executive officers and directors with those of our stockholders.

Under the guidelines, our CEO is expected to maintain ownership of Stem common stock representing five times his annual base salary, and each other executive officer is expected to maintain ownership of Stem common stock representing two times his or her annual base salary. Board members are each expected to maintain ownership of Stem common stock representing four times his or her annual cash retainer. Under the guidelines, our executives and board members have five years to satisfy the ownership requirements. During that time, directors and executive officers are expected to retain 50% of the net shares acquired upon stock option exercises and RSU vesting, until they achieve their minimum requirement under the guidelines.

As of March 31, 2025, all of our NEOs and board members were in compliance with our stock ownership guidelines.

EQUITY COMPENSATION PLAN INFORMATION

The following table sets forth information as of December 31, 2024 about our equity compensation plans, all of which have been approved by our stockholders (and does not take into account the potential effect of Proposal 2 to approve the amendment and restatement to the Stem, Inc. 2024 Equity Incentive Plan (for purposes of this document section, the “2024 Plan”)). As of that date, we had outstanding awards under three equity compensation plans: the 2009 Equity Incentive Plan (the “2009 Plan”), the 2021 Equity Incentive Plan (the “2021 Plan”) and the 2024 Plan. Awards currently may be granted only under our 2024 Plan.

DIRECTOR COMPENSATION

The Compensation Committee is responsible for periodically reviewing and approving the form and amount of compensation paid to our non-employee directors for their service on our Board and its committees. Generally, directors who are employees of the Company do not receive compensation for serving on the Board.

In making non-employee director compensation recommendations, the Compensation Committee takes various factors into consideration, including the responsibilities of directors generally, as well as committee chairs, and the form and amount of compensation paid to directors by peer companies.

As a general matter, our Compensation Committee annually reviews our non-employee director compensation. However, in 2024, the Committee determined that, given the Company’s then-current stock price and in the interest of conserving cash, it would not undertake a market review of non-employee director pay. As a result, for the second consecutive year, the Committee did not approve any non-employee director pay increases at that time.

Cash Compensation. The following table shows the cash retainer for service on the Board and various committees. Cash payments were made quarterly in arrears. Compensation for committee chair service is in lieu of compensation for committee membership, and not in addition to it.

Equity Compensation. Upon election or re-election to our Board and in connection with each annual meeting of stockholders, non-employee directors receive an annual equity grant of time-based RSUs with a target grant date fair value of $140,000, subject to an overall per-director limit of $600,000 on the total cash fees paid and value of equity granted in a single year. In 2024, each non- employee director was awarded 110,236 RSUs, which will vest in full on May 29, 2025, the anniversary of our 2024 Annual Meeting of Stockholders.

Gerard Cunningham Special Compensation. In addition to compensation earned for Board service, Mr. Cunningham received payments for his advisory services to the Board, including on the Board’s Software Strategy Working Group (an ad hoc non-Committee advisory body). See footnotes 3, 4 and 5 to the table below for details.
