ANNUAL MEETING OF STOCKHOLDERS OF
ALTUS POWER, INC.

TO BE HELD MAY 22, 2024

INTRODUCTION

The board of directors of Altus Power, Inc. (our “Board”) is soliciting proxies from stockholders for the 2024 annual meeting of stockholders (the “Annual Meeting”), and at any adjournment or adjournments thereof. The Annual Meeting is scheduled to be held on May 22, 2024, at 10:00 a.m. Eastern Time, in a virtual-only format at https://www.cstproxy.com/altuspower/2024.

This Proxy Statement relates to the solicitation of proxies by our Board for use at the Annual Meeting.

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS

The Securities and Exchange Commission’s e-proxy rules permit companies to post their proxy materials on the Internet and to provide only a Notice of Internet Availability of Proxy Materials to stockholders. On or about April 11, 2024, we will begin mailing a Notice of Internet Availability of Proxy Materials (the “Notice”) to all stockholders entitled to vote at the Annual Meeting informing them that our Proxy Statement, Annual Report for the fiscal year ended December 31, 2023 (the “Annual Report”) and voting instructions are available online. As more fully described in the Notice, all stockholders may choose to access our proxy materials via the Internet or may request to receive paper copies of the proxy materials. This process allows us to conserve natural resources and reduces the costs of printing and distributing the proxy materials, while providing our stockholders with access to the proxy materials in a fast and efficient manner.

Our Proxy Statement, Proxy Card and Annual Report are available at https://investors.altuspower.com.

INFORMATION ABOUT THE MEETING AND VOTING

Purposes of the Meeting

The purposes of the Annual Meeting are:

1

1.	To elect two (2) Class III directors, each to serve until the 2027 annual meeting of our stockholders;
2.	To ratify the appointment of Grant Thornton LLP ("Grant Thornton") as our independent registered public accounting firm for our fiscal year ending December 31, 2024; and
3.	To transact such other business as may properly come before the Annual Meeting or any adjournments and postponements thereof.

Stockholders Entitled to Vote at the Meeting

Our Board has established the close of business on March 28, 2024 as the “record date” for the Annual Meeting. This means that you are entitled to vote at the Annual Meeting and any adjournments thereof if our records show that you owned our Class A common stock, par value $0.0001 per share (our “Class A common stock”), at that time. As of the record date, 159,872,990 shares of our Class A common stock were issued and outstanding held by approximately 20 registered stockholders of record, and 996,188 shares of our Class B common stock, par value $0.0001 per share (our “Class B common stock”), were issued and outstanding, held by approximately six (6) registered stockholders of record. Each issued and outstanding share of Class A common stock as of the record date is entitled to one vote on each matter properly to come before the Annual Meeting. The holders of Class B common stock are not entitled to vote on any matters expected to come before the Annual Meeting. Each issued and outstanding share of Class A common stock can be voted only if the record owner of that share, determined as of the record date, is present by remote communication at the meeting or represented by proxy. A list of stockholders entitled to vote will be available for examination during the Annual Meeting at https://cstproxy.com/altuspower/2024.

Voting Shares That You Hold in Brokerage or Similar Accounts

Many stockholders hold their shares through a broker, bank or other nominee rather than directly in their own name. If you hold your shares in one of these ways, you are considered a beneficial owner, not a record owner, and you therefore have no direct vote on any matter to come before the Annual Meeting. Your broker, bank or nominee will send you voting instructions for you to use in directing the broker, bank or nominee in how to vote your shares. Your broker, bank or nominee may allow you to deliver your voting instructions via the telephone or the Internet.

If you hold your shares through a broker and you do not timely provide your broker with specific instructions on how to vote your shares, your broker will not be authorized to cast a vote on your behalf on Proposal 1 but will be authorized to cast a vote on your behalf, in its discretion, on Proposal 2. In such cases, a “broker non-vote” may be entered with respect to your shares on Proposal 1 to reflect that your broker was present with respect to your shares at the meeting but was not exercising voting rights on your behalf with respect to those shares. Broker non-votes will have no effect on the outcome of each proposal.

Your Voting Options on Each of the Proposals

If you hold shares of our Class A common stock, you may vote “for all”, “withhold all” (meaning you choose to withhold from the proxy holder named in the proxy card your authority to vote) or “for all except” (meaning you choose to withhold from the proxy holder named in the proxy card your authority to vote for the stricken nominee) with respect to the election of each nominee for Class III director (Proposal 1).

If you hold shares of our Class A common stock, you may vote “for,” “against” or “abstain” with respect to the proposal on the ratification of the appointment of Grant Thornton (Proposal 2).

If any other matter is presented at the Annual Meeting, your proxy provides that your shares of our Class A common stock, if eligible to vote on such matter, will be voted by the proxy holder named in the proxy card in accordance with his or her best judgment. At the time this Proxy Statement was first made available, we knew of no matters that needed to be acted on at the Annual Meeting, other than those discussed in this Proxy Statement.

4

Our Board’s Voting Recommendations

Our Board recommends that you vote, as applicable:

•FOR the election as director of each of the two (2) individuals named as the Board’s nominees for Class III director in this Proxy Statement (Proposal 1); and

•FOR the ratification of the appointment of Grant Thornton as our independent registered public accounting firm for our fiscal year ending December 31, 2024 (Proposal 2).

If any other matter is properly brought before the Annual Meeting, the Company - through the individual named in the proxy and acting as the “proxy holder,” or his or her designee, and pursuant to the blanket authorization granted under the proxy - will vote your shares on that matter in accordance with the discretion and judgment of the proxy holder.

Required Votes to Approve Each Proposal

If you are a holder of our Class A common stock, you are entitled to cast one vote per share for each of the two (2) nominees for election as Class III directors at the Annual Meeting, but you may not cumulate your votes (in other words, you may not cast votes representing two times the number of your shares entitled to vote in favor of a single nominee). Election of Class III directors shall be determined by a plurality of the votes cast in respect of the shares of Class A common stock present in person (including virtually) or represented by proxy at the meeting and entitled to vote on the election of directors, and the Class III director nominees who receive the greatest number of votes at the Annual Meeting (up to the total number of directors to be elected) will be elected.

With respect to each nominee, stockholders have the option to vote “for” either both nominees by choosing to vote “for all,” for one nominee by choosing to vote “for all except” and striking through the name of the nominee for whom they wish not to vote, or to vote against both nominees by choosing “withhold all” or for an individual nominee by choosing “for all except” and striking through the name of the nominee for whom they wish to withhold authority. Withheld votes will not affect the outcome of the vote on the election of directors. The election of directors is a non-routine matter. Therefore, brokerage firms do not have authority to vote customers’ unvoted shares held by the firms in street name for the election of directors. As a result, any shares not voted by a stockholder will be treated as a “broker non-vote.” Such broker non-votes will have no effect on the election of directors.

A majority of the votes cast in respect of the shares of Class A common stock present in person (including virtually) or represented by proxy at the Annual Meeting will approve: (i) the proposal to ratify the appointment of Grant Thornton as our independent registered public accounting firm for our fiscal year ending December 31, 2024; and (ii) all other matters that arise at the Annual Meeting. Only “for” and “against” votes will affect the outcome. Abstentions will have no effect on the ratification of the appointment of Grant Thornton as our independent registered public accounting firm. This is a routine matter. Therefore, brokerage firms have authority to vote

5

customers’ unvoted shares held by the firms in street name on this proposal. If a broker does not exercise this authority, such broker non-votes will have no effect on the results of this vote.

Please note, however, that because the vote on the ratification of Grant Thornton is advisory in nature, our Board and the audit committee will consider the results of the vote, but such results will not be binding upon our Board or our audit committee.

Quorum

The presence, virtually online or by proxy, of holders of at least a majority of the total number of outstanding shares entitled to vote of Class A common stock with respect to Proposal 1 and Proposal 2 is necessary to constitute a quorum for the transaction of business at the Annual Meeting. Abstentions, withheld votes and “broker non-votes”, if any, will be included in the calculation of the number of shares considered to be present at the meeting to determine whether a quorum has been established.

Voting on Possible Other Matters

We are not aware that any person intends to propose that any matter, other than the two numbered proposals specifically described by this Proxy Statement, be presented for consideration or action by our stockholders at our Annual Meeting. If any such other matter should properly come before the meeting, however, favorable action on such matter would generally require the affirmative vote of a majority of the votes cast, unless our third amended and restated certificate of incorporation or second amended and restated bylaws or applicable laws or regulations require otherwise. If you vote by proxy, you will be granting the proxy holder authority to vote your shares on any such other matter in accordance with his discretion and judgment.

Revocation of Proxies or Voting Instructions

A stockholder of record who has delivered a proxy card in response to this solicitation may revoke it before it is exercised at the Annual Meeting by executing and delivering a timely and valid later-dated proxy, by a timely and valid later Internet vote, by voting by remote communication at the meeting or by giving written notice to the Secretary. Attendance at the Annual Meeting online will not have the effect of revoking a proxy unless a stockholder gives proper written notice of revocation to the Secretary before the proxy is exercised or the stockholder votes by remote communication at the Annual Meeting. Beneficial owners who have directed their broker, bank or nominee as to how to vote their shares should contact their broker, bank or nominee for instructions as to how they may revoke or change those voting directions.

Solicitation of Proxies

Our Board is making this solicitation of proxies for our Annual Meeting. We will bear all costs of such solicitation, including the cost of preparing and distributing this Proxy Statement and the enclosed form of proxy and including the cost of hosting the virtual meeting. After the initial

6

distribution of this Proxy Statement, proxies may be solicited by mail, telephone, or personally by directors, officers, employees or agents of the Company. Brokerage houses and other custodians, nominees and fiduciaries will be requested to forward soliciting materials to beneficial owners of shares held by them for the accounts of beneficial owners, and we will pay their reasonable out-of-pocket expenses.

Emerging Growth Company

We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. As an emerging growth company, we may take advantage of specified reduced disclosure and other requirements that are otherwise applicable generally to public companies, including:

•reduced disclosure about our executive compensation arrangements;

•exemption from the requirements to hold non-binding advisory votes on executive compensation and golden parachute payments; and

•exemption from the auditor attestation requirement in the assessment of our internal control over financial reporting.

We may take advantage of these exemptions until the last day of the fiscal year following the fifth anniversary of our initial public offering or such earlier time that we are no longer an emerging growth company. We would cease to be an emerging growth company earlier if we have more than $1.235 billion in annual revenue, we have more than $700 million in market value of our stock held by non-affiliates (and we have been a public company for at least 12 months and have filed one annual report on Form 10-K with the Securities and Exchange Commission (the “SEC”) or we issue more than $1 billion of non-convertible debt securities over a three-year period. For so long as we remain an emerging growth company, we are permitted, and intend, to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. We may choose to take advantage of some, but not all, of the available exemptions.

In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected not to “opt out” of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we will adopt the new or revised standard at the time private companies adopt the new or revised standard and will do so until such time that we either (i) irrevocably elect to “opt out” of such extended transition period or (ii) no longer qualify as an emerging growth company. Therefore, the reported results of operations contained in our financial statements may not be directly comparable to those of other public companies.

PROPOSAL 1
ELECTION OF DIRECTORS

As of the date of this Proxy Statement, our Board consists of seven (7) directors. In accordance with the terms of our third amended and restated certificate of incorporation and second amended and restated bylaws, our Board is divided into three classes (Classes I, II and III), each to serve a three-year term, except for the directors’ initial terms, and a Class B director, to serve a one-year term, except for such director’s initial term. The Class I directors, Richard N. Peretz and Tina C. Reich, have terms expiring at the 2025 annual meeting of stockholders, the Class II directors, Christine R. Detrick and Robert M. Horn, have terms expiring at the at the 2026 annual meeting of stockholders, and the Class III directors, Lars R. Norell and Gregg J. Felton, have terms expiring at the Annual Meeting. Robert Bernard is the Class B director with a term expiring at the Annual Meeting. At each annual meeting of stockholders, the successors to Class I, Class II or Class III directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following the election. We are nominating the two (2) current Class III directors listed below for re-election. If re-elected, each of these two (2) Class III nominees will serve on our Board until the 2027 annual meeting, or until his successor is duly elected and qualified in accordance with our third amended and restated certificate of incorporation and second amended and restated bylaws, or his earlier death, resignation or removal.

At each annual meeting of stockholders, the successor to the Class B director whose term then expires will be elected to serve from the time of election and qualification until the next annual meeting following the election so long as there is an election of directors at such meeting. The majority of the holders of our Class B common stock consented to the re-election of Robert Bernard as the Class B director effective as of the date of the Annual Meeting to serve on our Board until the 2025 annual meeting, or until his successor is duly elected and qualified in accordance with our third amended and restated certificate of incorporation and second amended and restated bylaws, or his earlier death, resignation or removal.

Below is certain information concerning our Board’s nominees for election at Annual Meeting. The biographies of each of the nominees below contain information regarding the experiences, qualifications, attributes or skills that caused the nominating and corporate governance committee and our Board to determine that the person should be re-elected as a director of the Company.

Following the director biographies is information concerning our corporate governance structure, including descriptions of the standing committees of our Board, namely our audit, compensation and nominating and corporate governance committees. The directors serving on each committee are listed in the descriptions below. Our directors may also serve on other committees of our Board and the boards of directors of the Company’s subsidiaries that are not required to be described by this Proxy Statement and which are therefore not identified in the information below.

8

Elsewhere in this Proxy Statement you will find information concerning the number of shares of our common stock that are beneficially owned by each of our directors (see “Security Ownership of Certain Beneficial Owners and Management”) and information regarding the compensation of our directors (see “Executive Officer and Director Compensation”). We urge you to review all of this information when deciding how to vote on Proposal 1.

Required Vote of Stockholders

Election of Class III directors shall be determined by a plurality of the votes cast in respect of the shares of Class A common stock present in person (including virtually) or represented by proxy at the Annual Meeting and entitled to vote on the election of directors, and the Class III director nominees who receive the greatest number of votes at the Annual Meeting (up to the total number of directors to be elected) will be elected.

With respect to each nominee, Class A stockholders have the option to vote “for” both of the nominees, “withhold” their vote from both of the nominees or “withhold” their vote from any one of the nominees by choosing to vote “for all except” and striking through the name of the individual nominee for whom they wish to withhold authority. Withheld votes and broker non-votes will not affect the outcome of the vote on Proposal 1.

Our Board recommends that you vote FOR the two (2) of the Class III nominees named below.

The following persons have been nominated for election to our Board:

THE BOARD OF DIRECTORS AND CERTAIN GOVERNANCE MATTERS

Our Board manages or directs the business and affairs of the Company, as provided by the Delaware General Corporation Law (the “DGCL”), and conducts its business through meetings of the Board and three standing committees: the audit committee, the compensation committee and the nominating and corporate governance committee.

Our Board evaluates the Company’s corporate governance policies on an ongoing basis with a view towards maintaining the best corporate governance practices in the context of the Company’s current business environment and aligning our governance practices closely with the interests of our stockholders. Our Board and management value the perspective of our

12

stockholders and encourage stockholders to communicate with the Board as described under “Communication with Directors” below.

As of December 31, 2023, Mr. Felton, Mr. Norell, Ms. Detrick, Mr. Peretz, Ms. Brink, Mr. Horn and Ms. Reich served as directors of the Company and Mr. Concannon served as the Class B director of the Company. Ms. Daley who was previously on our Board, resigned from our Board on January 18, 2023 and Diane D. Brink was appointed to fill the vacancy on January 24, 2023, and she served in that capacity until her resignation on March 19, 2024. Ms. Coyne who previously served on our Board, resigned on August 16, 2023 and Tina C. Reich was appointed to fill the vacancy on November 1, 2023. Mr. Concannon, who was previously our Class B Director, resigned from our Board on February 27, 2024 and Robert C. Bernard was appointed by the Class B Stockholders as the Class B Director on February 27, 2024.

Composition of the Board

We have a classified Board, with two directors in Class I (Richard N. Peretz and Tina C. Reich), two directors in Class II (Christine R. Detrick and Robert M. Horn) and two directors in Class III (Lars R. Norell and Gregg J. Felton). In addition, Robert C. Bernard serves as the Class B director.

Board Leadership Structure

Currently, the role of Chairperson of the Board is separated from the role of the Co-Chief Executive Officers. We believe that separating these positions allows our Co-Chief Executive Officers to focus on our day-to-day business, while allowing the Chairperson to lead the Board in his or her fundamental role of providing advice to, and independent oversight of management. Our Board recognizes the time, effort, and energy that the Co-Chief Executive Officers are required to devote to their position in the current business environment, as well as the commitment required to serve as our Chairperson, particularly as the Board’s oversight responsibilities continue to grow. While our second amended and restated bylaws and our corporate governance guidelines do not require that our chair and chief executive officer positions be separate, our Board believes that having separate positions is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance. Our Board has concluded that our current leadership structure is appropriate at this time. However, our Board will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate.

Director Independence

The New York Stock Exchange (“NYSE”) listing standards require that a majority of the board of directors of a company listed on NYSE be composed of “independent directors.” An “independent director” is defined generally as a person that, in the opinion of the company’s board of directors, has no material relationship with the listed company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the company). Based on information provided by each director concerning his or her background, employment

13

and affiliations, including family relationships, the Board has determined that each of Christine R. Detrick, Richard N. Peretz, Robert M. Horn, Tina C. Reich and Robert C. Bernard are independent directors under the NYSE listing standards. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors or any other board committee: (1) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or (2) be an affiliated person of the listed company or any of its subsidiaries. Based on information provided by each director concerning his or her background, employment and affiliations, including family relationships, the Board has determined that each of the members of the audit committee of our Board, Richard N. Peretz, Tina C. Reich and Christine Detrick is an independent director under Rule 10A-3 of the Exchange Act. In making these determinations, the Board considered the current and prior relationships that each non-employee director has and will have with the Company and all other facts and circumstances that the Board deemed relevant in determining independence, including the beneficial ownership of the Company’s common stock by each non-employee director (and related entities) and certain transactions involving them described in the section entitled “Certain Relationships and Related Person Transactions.”

Committees and Attendance

Our Board held eight (8) meetings during 2023. During that time, no member of our Board attended fewer than 75% of the aggregate of (i) the total number of meetings of our Board (held during the period for which he was a director) and (ii) the total number of meetings held by all committees of our Board on which he served (held during the period that such director served).

In addition to regular meetings of our Board, the Company’s independent directors typically meet in executive sessions without management participation after each Board meeting.

The standing committees of our Board consist of an audit committee, a compensation committee and a nominating and corporate governance committee. Our Board may from time to time establish other committees.

Role of Board in Risk Oversight Process

Our Board has an active role, as a whole and also at the committee level, in overseeing the management of our risks. Our Board is responsible for general oversight of risks and regular review of information regarding our risks, including credit risks, liquidity risks and operational risks. The compensation committee is responsible for overseeing the management of risks associated with our compensation policies and practices. The audit committee is responsible for overseeing the management of risks relating to accounting matters and financial reporting. The nominating and corporate governance committee is responsible for overseeing the management of risks associated with potential conflicts of interest. Although each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is

14

regularly informed through discussions from committee members about such risks. Because of the role of the Board and its committees in risk oversight, the Board believes that any leadership structure that it adopts must allow it to effectively oversee the management of regulatory risks, compliance risks, and the risks relating to our operations. Our Board believes its current leadership structure enables it to effectively provide oversight with respect to such risks.

Audit Committee

Richard N. Peretz, Diane D. Brink and Tina C. Reich were the members of our audit committee as of December 31, 2023. Mr. Peretz is the chairperson of our audit committee. Ms. Daley resigned from the Board, audit committee and compensation committee on January 18, 2023 and Ms. Brink was appointed to fill each of those vacancies on January 24, 2023. Ms. Coyne resigned from the Board, audit committee and nominating and corporate governance committee on August 16, 2023 and Tina C. Reich was appointed to fill the vacancy on the Board and on the nominating and corporate governance committee on November 1, 2023. Ms. Detrick was appointed to fill the vacancy on the audit committee on August 16, 2023 and served in such interim capacity until November 1, 2023, when the Board appointed Ms. Brink to the audit committee to fill such vacancy. Ms. Brink resigned from the Board, the audit committee and compensation committee on March 19, 2024, and the Board appointed Ms. Detrick to the audit committee to fill such vacancy. Each member of the audit committee qualifies as an independent director under the NYSE corporate governance requirements and the independence requirements of Rule 10A-3 of the Exchange Act. Richard N. Peretz qualifies as an “audit committee financial expert” as such term is defined in Item 407(d)(5) of Regulation S-K and meets the financial literacy requirements of the NYSE.

Our Board adopted a written charter for the audit committee, which is available on our website at https://investors.altuspower.com.

During the fiscal year ended December 31, 2023, the Company’s audit committee met six (6) times, with allmembers of the audit committee attending at least 75% of such meetings. The report of the audit committee is included in this Proxy Statement under “Report of the Audit Committee.”

Commitment to Sustainability

Altus Power was founded to change modern power generation and consumption patterns. Our mission to create a clean electrification ecosystem that can provide renewable energy to every business, home and electric vehicle is intrinsically linked to clean, renewable power as the foundation for a sustainable future.

We believe that leadership in environmental, social and governance practices is central to accomplishing our mission, so we continually take steps to isolate and address the environmental and social risks of our operations and products. To this end, our management has established a corporate social responsibility committee that is dedicated to improving the sustainability practices throughout the Company. Our team is passionate about empowering communities and businesses to accelerate the global energy transition while also doing everything we can to foster a diverse, inclusive, and innovative corporate culture at Altus Power.

Our sustainability efforts are organized into the three sustainability pillars: Environmental, Social and Governance. We report how we oversee and manage sustainability factors in an annual sustainability report, which can be found by visiting https://www.altuspower.com/sustainability. In 2023, we joined the United Nations Global Compact and are committed to adhering to its principles-based approach to responsible business.

Environmental

Our Environmental Pillar illustrates how we are committed to providing clean, affordable energy to our customers; maintaining robust environmental management safeguards that protect the environment and communities we build in, and by striving for carbon-neutral corporate operations. Understanding the wider environmental impacts of our investing and operating decisions through integration of clear, actionable, and measurable sustainability practices across our business units will help us in building community and infrastructure resilience and sustainability.

The solar arrays that we build and maintain will produce clean and affordable energy for years to come, displacing utility power generated from fossil fuels and directly enabling households and corporations to reduce their own carbon footprint. Altus is empowering our residential and corporate customers, partners, and communities to reach their sustainability goals.

In addition to empowering others on their sustainability journey, it is equally important that we consider the environmental impacts of our own business. We strive to be industry leaders in environmental stewardship. We maintain a robust environmental management program to ensure we protect the environment in the communities where we build and are implementing strategies to address the emissions involved with building a solar project. Whenever possible, Altus partners with businesses to provide North American manufactured solar panels. Finally, we are

19

developing processes to measure and track the Scope 1, Scope 2, and material Scope 3 carbon emissions from our business.

Social

Our Social Pillar is committed to enriching the communities in which we live, work, and serve. By building a diverse and inclusive work force and ensuring a safety-first workplace for our employees, we work towards protecting the interests of all our stakeholders.

We continue to invest into building our team. With high aspirations for growing the business we have also focused on growing the team. In expanding our team, our priority was attracting a diverse group of talented individuals across the United States. We recognize that our Company’s resiliency is strengthened by our differences. Having a diverse and inclusive workplace is critical to the innovation and development of new ideas. This foundation is essential for us to meet our business objectives, and translates into our commitment to diversity, equity and inclusion. We are focused on attracting and hiring diverse candidates, developing and mentoring our employees, and retaining and challenging our talented individuals as they grow at Altus.

Governance

Our Governance Pillar is focused on adhering to the highest standards of corporate governance. Altus Power maintains a comprehensive governance framework that builds transparency, accountability, regulatory compliance, risk management, and responsible management into all our business endeavors. We believe that strong governance is the foundation on which all resilient and successful companies are built. We consistently strive for the highest standards of ethical business conduct and the continued development of strong and resilient governance practices. Our Board oversees senior management in the ethical operation of the company to ensure actions taken are in the best interest of shareholders and stakeholders. Through guidance from our Board and the internal corporate social responsibility committee, we reinforce senior leadership alignment on ESG strategy across each of our business units.

All of our actions and each of our ESG pillars are underpinned by the goal of driving the clean energy transition of our customers across the United States.

Director Nomination Process

Our Board has delegated to the nominating and corporate governance committee the task of identifying, considering, recruiting, reviewing and recommending a slate of director nominees to be proposed by the Board to the stockholders, and recommending any director nominees to be elected by the Board to fill interim vacancies. It is the policy of our Board that directors should possess strong personal and professional ethics, integrity and values; be business savvy and genuinely interested in the Company; and be committed to representing the long-term interests of the stockholders. The Board is also intended to encompass a range of talents, ages, skills, diversity and expertise sufficient to provide sound and prudent oversight with respect to the operations and interests of the business. Selection of candidates includes consideration of a range of diversity perspectives, including, but not limited to, professional and personal background,

20

experience, strategic thinking, relevant skills, business and operations expertise, relevant knowledge and length of service.

The biography for each of the director nominees included herein indicate each nominee’s experience, qualifications, attributes and skills that led our nominating and corporate governance committee and our Board to conclude each such director should continue to serve as a director of our Company. Our nominating and corporate governance committee and our Board believe that each of the nominees has the individual attributes and characteristics required of each of our directors, and the nominees as a group possess the skillset and specific experience desired of our Board as a whole.

Stockholders have the right under our second amended and restated bylaws to directly nominate director candidates for election at an annual meeting of stockholders, without any action or recommendation on the part of the nominating and corporate governance committee or our Board, by submitting to the Company as to each nominee that the stockholder proposes for election or re-election as a director all information relating to such nominee that would be required to be disclosed in solicitations of proxies for the election of such nominee as a director pursuant to Regulation 14A under the Exchange Act and such nominee’s written consent (I) to be named as a nominee in the Company’s proxy statement, proxy card, and/or ballot, if the Board approves such inclusion, and (II) to serve as a director if elected. The Company may require any proposed nominee to furnish such other information as it may reasonably require to determine the eligibility of such proposed nominee to serve as a director of the Company and to determine the independence of such director under the Exchange Act and the rules and regulations thereunder and of the NYSE. Any such nomination must be made by a stockholder of record of the Company at the time of making such nomination and meet such other requirements as are set forth in the Company’s second amended and restated bylaws. Such nomination information should be submitted to: Altus Power, Inc., 2200 Atlantic Street, 6th Floor, Stamford, CT 06902, Attention: Corporate Secretary.

Director Attendance at Annual Meeting

Each director who is up for election at the Annual Meeting of Stockholders or who has a term that continues after the Annual Meeting is expected to attend the Annual Meeting. The Company does not have a formal policy with respect to attendance of annual meetings of stockholders by its directors; however, all members of the Board, including directors who are up for election at the Annual Meeting, are encouraged to attend.

EXECUTIVE COMPENSATION

Compensation Discussion and Philosophy

As an intentionally lean, high-growth company in the in-demand renewable energy space where talent remains scarce, drawing from high cost-of-living communities of New York, New Jersey and Connecticut and its suburbs, we aim to offer competitive compensation to attract and retain our top tier talent. We work with specialized recruiters focused on our industry and this tri-state area to benchmark market compensation, as applicable. We consider overall company performance, individual performance, and the impact of the role in determining base and cash bonus for both our executive leadership and senior management employees. We reward exceptional contributions and results, as determined by management given the contributions or results. Our compensation philosophy recognizes the higher demands we place on our people as a lean organization. We believe it is important to further incentivize our employees by issuing RSUs to provide our dedicated team the opportunity to create long-term value, which align our employees’ actions with the interests of shareholders, which is one of the main reasons we issue equity-based compensation.

Introduction

This section provides an overview of the Company’s executive compensation programs, including a narrative description of the material factors necessary to understand the information disclosed in the summary compensation table below. Throughout this section, unless otherwise noted, “we,” “us,” “our” and similar terms refer to the Company and its subsidiaries.

For the year ended December 31, 2023, our named executive officers (“Named Executive Officers” or “NEOs”) were:

•Gregg Felton, Co-Chief Executive Officer;

•Lars Norell, Co-Chief Executive Officer;

•Anthony Savino, Chief Construction Officer; and

•Dustin Weber, Chief Financial Officer.

The compensation committee of our Board sets the executive compensation philosophy and oversees and determines the compensation and benefits of our Co-Chief Executive Officers and other executive officers of the Company. The compensation committee also oversees our management equity programs and is committed to providing an executive compensation program that supports the alignment of our management team’s interests with those of our stockholders. With respect to base salaries, annual incentive compensation and long-term incentives, the compensation committee establishes the compensation mix, performance measures, goals, targets and business objectives based on the Company’s competitive marketplace. In setting

26

compensation, the compensation committee receives input from Pearl Meyer (“PM”), its compensation consultant, to provide compensation that appropriately attracts, retains, and incentivizes executives who are able to execute on our vision to reduce carbon emissions, increase resilience to climate change and execute our operational plans with a focus on sustainable long-term growth.

In addition to base salary and annual cash bonuses, the Company grants stock-based awards under the 2021 Omnibus Incentive Plan, as amended (the “Incentive Plan”), which include awards with time-based and performance-based vesting. In addition, the NEOs are eligible to participate in the employee stock purchase plan on the same basis as all of our eligible employees. The compensation committee’s focus on stock-based compensation is designed to promote the Company’s interests and align executive incentives with the interests of our stockholders.

The cash bonuses are designed to reward short term achievements and are calculated based on adjusted EBITDA as well as certain non-financial metrics, such as achievement of certain strategic and operational goals for year. Continued employment on the vesting dates are the requirements the time-based equity. In addition to continued employment, long term achievements based on total shareholder return are required under the parameters of the performance equity.

Our Board has adopted stock ownership guidelines establishing a minimum stock ownership requirement for executive officers and non-employee directors. Shares unowned outright, shares held in trust for their benefit, shares purchased under the ESPP, and shares underlying vested incentives count towards satisfaction of these Guidelines (as described therein). The table provides the requirements for each of our Co-Chief Executive Officers, other executive officers, and outside directors with respect to minimum ownership of our stock.

Position	Multiple of annual base salary or annual base cash retainer	Must achieve the applicable multiple by the later of (a)(i) the 2027 annual meeting of stockholders in the case of non-employee directors or (ii) March 24, 2027 and (b) these number of years from the date the person was appointed
Co-Chief Executive Officers	6x	5 years
Other Executive Officers	3x	5 years
Outside Directors	4x	5 years

27

Until the applicable threshold is met, executive officers and non-employee directors are required to retain at least 50% of the shares, net of applicable tax withholding and the payment of any exercise or purchase price (if applicable), received upon the vesting or settlement of equity awards or the exercise of stock options. Our executive officers will have until the later of March 24, 2027 or five years after the date the person was initially designated an executive officer of the Company to achieve the applicable level of ownership. Our non-employee directors will have until the later of our 2027 annual meeting of stockholders or five years after the date such non-employee director is appointed to achieve the applicable level of ownership. Each of tour NEOs have met such stock ownership guidelines. The Company has adopted a clawback policy as required pursuant to the rules of the New York Stock Exchange and SEC regulations implementing the incentive-based compensation recovery (clawback) provisions of the Dodd-Frank Act.

We also prohibit our executive officers from engaging in short-term trading; short sales of our securities; purchasing or selling puts, calls or other derivative securities based on our securities; entering into hedging or monetization transactions; holding our securities in margin accounts or pledging our securities as collateral for a loan. See “Prohibition on Hedging and/or Pledging our Common Stock.”

Management Equity Incentive Letter Grants to Named Executive Officers

On July 12, 2021, we entered into the Management Equity Incentive Letter, in connection with the merger of the Company with CBRE Acquisition Holdings, Inc., with each of Mr. Felton and Mr. Norell. Pursuant to the Management Equity Incentive Letter, on February 15, 2022, the compensation committee granted to Mr. Felton and Mr. Norell, together with other senior executives, including Mr. Savino and Mr. Weber, RSUs under the Incentive Plan that are subject to time-based vesting and, for our NEOs and certain other executives, eighty percent (80%) of such RSUs also further subject to performance-based vesting, with respect to an aggregate five percent (5%) of the Company’s Class A common stock on a fully diluted basis, excluding the then-outstanding shares of the Company’s Class B common stock or any shares of the Company’s Class A common stock into which such shares of the Company’s Class B common stock are or may be convertible. Subject to continued employment on each applicable vesting date, the time-based RSUs generally vest 33 1/3% on each of February 15, 2025, February 15, 2026 and February 15, 2027, and the performance-based RSUs were eligible to vest with respect to 33 1/3% of the award upon the achievement of the above time-based requirement and the achievement of a hurdle representing a 25% annual compound annual growth rate measured based on an initial value of $10.00 per Share (i.e. on each of the third anniversary, the fourth anniversary, and the fifth anniversary of the date of grant, the stock price performance hurdle is $19.53, $24.41, $30.51, respectively), which vesting is eligible until the fifth anniversary of grant date. On March 28, 2024, these vesting conditions of such performance-based RSUs were amended by the compensation committee to set the hurdles at $14.00, $18.00 and $22.00, respectively. The amounts reported in the “Stock Awards” column reflect the aggregate grant date fair value of stock awards granted during fiscal year 2022, computed in accordance with FASB ASC Topic 718.

401(k) Plan

We maintain a 401(k) plan that provides eligible U.S. employees, including our NEOs, with an opportunity to save for retirement on a tax advantaged basis. Eligible employees are able to defer eligible compensation up to certain limits imposed by the U.S. Internal Revenue Code (the “Code”), which are updated annually in accordance with guidance from the U.S. Internal Revenue Service. We have the ability to make matching and discretionary contributions to the 401(k) plan, subject to applicable service-based vesting, but we have not yet done so for any employees, including our NEOs, to date.

REPORT OF THE AUDIT COMMITTEE

The information contained in this report shall not be deemed to be “soliciting material” or “filed” or incorporated by reference in future filings with the SEC, or subject to the liabilities of Section 18 of the Exchange Act, except to the extent that the Company specifically incorporates it by reference into a document filed under the Securities Act or the Exchange Act.

We operate in accordance with a written charter adopted by our Board and reviewed annually by the audit committee. We are responsible for overseeing the quality and integrity of the Company's accounting, auditing and financial reporting practices. In accordance with the rules of the SEC and NYSE, the audit committee is composed entirely of members who are independent, as defined by the listing standards of NYSE and the Company's corporate governance guidelines. Further, our Board has determined that Richard N. Peretz qualifies as an “audit committee financial expert” as such term is defined in Item 407(d)(5) of Regulation S-K and meets the financial literacy requirements of the NYSE.

We believe that we fully discharged our oversight responsibilities as described in our charter, including with respect to the audit process. We reviewed and discussed our audited financial statements for the fiscal year ended December 31, 2023, with management and Grant Thornton. Management has the responsibility for the preparation of Altus Power, Inc.’s financial statements, and Grant Thornton has the responsibility for the audit of those financial statements. The audit committee discussed with Grant Thornton the matters required to be discussed by Public Company Accounting Oversight Board, or PCAOB, Auditing Standard No. 1301 and the SEC. We received the written communication letter from Grant Thornton pursuant to Rule 3526, Communication with Audit Committees Concerning Independence, of the PCAOB, concerning any relationships between Grant Thornton and the Company and the potential effects of any disclosed relationships on Grant Thornton’s independence, and discussed with Grant Thornton its independence. We reviewed with Grant Thornton their audit plans, audit scope, identification of audit risks and their audit efforts, and discussed and reviewed the results of Grant Thornton’s audit of the Company's financial statements both with and without management.

The audit committee considered that no fees were paid to Grant Thornton for the provision of non-audit related services.

Based on these reviews and discussions with management and Grant Thornton, we approved the inclusion of Altus Power, Inc.’s audited financial statements in its Annual Report for filing with the SEC.

The audit committee has also appointed Grant Thornton as the Company's independent registered public accounting firm for fiscal year ending 2024, subject to ratification of the stockholders at the Annual Meeting.

The Company’s Related Party Transactions

The following is a description of our related person transactions during 2023.

Transactions with Blackstone and its Subsidiaries

APAF III Term Loan and APACF II Facility

On February 15, 2023, the Company, through its subsidiaries, APA Finance III Borrower, LLC (the “Borrower”) and APA Finance III Borrower Holdings, LLC (“Holdings”), entered into a new long-term funding facility under the terms of a credit agreement among the Borrower, Holdings, Blackstone Asset Based Finance Advisors LP, which is an affiliate of the Company, U.S. Bank Trust Company, N.A., as administrative agent, U.S. Bank N.A., as document custodian, and the lenders party thereto (the “APAF III Term Loan”).

Under the APAF III Term Loan and APACF II Facility, subsidiaries of The Blackstone Group (“Blackstone”), a related party, serve as agents between the Company and a consortium of third-party lenders, pursuant to which during the years ended December 31, 2023, the Company paid $1.3 million of loan issuance costs to Blackstone.

Lease Agreements with Link Logistics

During the year ended December 31, 2023, the Company obtained a right to use rooftops to develop and operate solar facilities under lease agreements with subsidiaries of Link Logistics Real Estate Management LLC (“Link Logistics”), a Blackstone portfolio company. As of December 31, 2023, the Company recognized operating lease assets and operating lease liabilities of $24.3 million in the consolidated balance sheet related to these leases, which have a weighted average remaining lease term of 30 years. During the year ended December 31, 2023, lease expense and payments made under these leases were not material.

Transactions with CBRE and its Subsidiaries

Master Services Agreement

On June 13, 2022, the Company, through its wholly-owned subsidiary, entered into a Master Services Agreement ("MSA") with CBRE under which CBRE assists the Company in developing solar energy facilities. For the year ended December 31, 2023, the Company incurred $0.5 million for development services provided under the MSA. As of December 31, 2023, there was $0.1 million due to CBRE for development services provided under the MSA.

Other Related Party Transactions

The Company has an employee who is the daughter of Mr. Savino, Chief Construction Officer. The employee reports indirectly to Mr. Savino but he does not control her compensation and she has been an employee of the Company since 2014. The employee’s aggregate compensation for 2023 was over $120,000 and is commensurate with other employees of the Company in her position.

The Company has retained Cozen O’Connor, via an engagement letter, whereby Cozen O’Connor provides legal services, in particular, with respect to Exchange Act reporting, corporate governance and securities compliance matters. Melissa Boulan, Chief People Officer’s brother, John Gallaghan, is a Member of Cozen O’Connor in the Subrogation & Recovery and Self-insured Recovery practice areas. Mr. Gallaghan does not work on matters for the Company,

42

his practice is unrelated to the work that the Company requires and he is not involved in the negotiation of the engagement letter with the Company.

Policies and Procedures for Related Party Transactions

In accordance with the Policy, we have policies and procedures designed to minimize potential conflicts of interest arising from any dealings it may have with its affiliates and to provide appropriate procedures for the disclosure of any real or potential conflicts of interest that may exist from time to time. Specifically, pursuant to its charter, the audit committeewill have the responsibility to review related party transactions. It is anticipated that under the related person transaction policy, the related person in question or, in the case of transactions with a beneficial holder of more than 5% of our voting stock, an officer with knowledge of a proposed transaction, will be required to present information regarding the proposed related person transaction to our audit committee (or to another independent body of the Board) for review. To identify related person transactions in advance, Altus expects to rely on information supplied by its executive officers, directors and certain significant stockholders. In considering related person transactions, our audit committee is expected to take into account the relevant available facts and circumstances, which may include, but are not limited to:

•the related person’s interest in the transaction;

•the approximate dollar value of the amount involved in the transaction;

•the approximate dollar value of the amount of the related person’s interest in the transaction without regard to the amount of any profit or loss;

•whether the transaction was undertaken in the ordinary course of business;

•whether the transaction with the related person is proposed to be, or was, entered into on terms no less favorable to Altus than terms that could have been reached with an unrelated third party;

•the purpose of, and the potential benefits to us of, the transaction; and

•any other information regarding the transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.

Our audit committee will approve only those transactions that it determines are fair to us and in our best interests.

43

PROPOSAL 2
RATIFICATION OF THE APPOINTMENT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

In accordance with its charter, the audit committee of our Board has selected the firm of Grant Thornton LLP (“Grant Thornton”), an independent registered public accounting firm, to be the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024, and our Board is asking stockholders (on a non-binding advisory basis) to ratify that appointment. Grant Thornton served as Altus’s independent registered public accounting firm for the audit of its financial statements for the fiscal year ending December 31, 2023. We are not required to have the stockholders ratify the appointment of Grant Thornton as our independent registered public accounting firm. We nonetheless are doing so because we believe it is a matter of good corporate practice. If the stockholders do not ratify the appointment, the audit committee will reconsider the retention of Grant Thornton, but ultimately may decide to retain Grant Thornton as the Company’s independent registered public accounting firm. Even if the appointment is ratified, the audit committee, in its discretion, may change the appointment at any time if it determines that such a change would be in the best interests of the Company and its stockholders.

Before selecting Grant Thornton, the audit committee carefully considered that firm’s qualifications as an independent registered public accounting firm for the Company. This included a review of its performance for Altus in prior year, including the firm’s efficiency, integrity and competence in the fields of accounting and auditing. The audit committee has expressed its satisfaction with Grant Thornton in all of these respects.

Representatives of Grant Thornton will be present at the Annual Meeting, will have the opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions.

Change in Independent Registered Public Accounting Firm

As reported in the Company’s Form 8-K filed with the SEC on September 1, 2023, on August 31, 2023, the audit committee of the Board of Directors approved the appointment of Grant Thornton, as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2023, effective immediately concurrent with the dismissal of Deloitte & Touche LLP (“Deloitte”). During the Company’s two most recent fiscal years ended December 31, 2023 and 2022, neither the Company nor anyone on its behalf consulted Grant Thornton regarding any of the matters set forth in Item 304(a)(2)(i) or (ii) of Regulation S-K.

The audit committee conducted a competitive process to determine the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2023. Several independent accounting firms were invited to participate in this process, including Deloitte, which had been previously engaged as the Company’s independent registered public accounting firm.

44

As a result of this competitive process, the decision to change the Company’s independent registered public accounting firm and, accordingly, to dismiss Deloitte, was approved by the Audit Committee on August 31, 2023, and Deloitte was dismissed effective as of August 31, 2023.

Deloitte’s reports on the Company’s consolidated financial statements for the fiscal years ended December 31, 2022 and 2021, respectively, did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

During the Company’s fiscal years ended December 31, 2022 and 2021, respectively, and the subsequent interim period through August 31, 2023, there were no (i) disagreements (within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions thereto) with Deloitte on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure that, if not resolved to the satisfaction of Deloitte, would have caused Deloitte to make reference thereto in its reports covering the Company’s consolidated financial statements for such periods and (ii) reportable events (as defined in Item 304(a)(1)(v) of Regulation S-K), except for the disclosure of the material weaknesses in the Company's internal controls over financial reporting as disclosed in Part II, Item 9A of the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

Audit Fees and Services

Audit and other fees billed to us by Grant Thornton and Deloitte for the fiscal years ended December 31, 2023 and December 31, 2022 are as follows:

45

All Other Fees. We did not pay Grant Thornton or Deloitte for any other services for each of the year ended December 31, 2023 and December 31, 2022.

Required Vote of Stockholders

The affirmative vote of a majority of the votes cast by holders of shares of common stock who are present by remote communication or by proxy at a meeting at which a quorum is present is required (on a non-binding advisory basis) to ratify the appointment of Grant Thornton. Abstentions will have no effect on the results of this vote.

Our Board recommends that you vote FOR the proposal to ratify Grant Thornton as the Company’s registered independent public accounting firm for 2024 (Proposal 2).

DELINQUENT SECTION 16(a) REPORTS

Section 16(a) of the Exchange Act requires the Company’s directors and executive officers and persons who beneficially own more than 10% of the Company’s common stock to file with the SEC reports showing initial ownership of and changes in ownership of the Company’s common stock and other registered equity securities. Based solely upon our review of the copies of such forms or written representations from certain reporting persons received by us with respect to fiscal year 2022, the Company believes that its directors and executive officers and persons who own more than 10% of a registered class of its equity securities have complied with all applicable Section 16(a) filing requirements for fiscal year 2023, except with respect to: a Form 4 for Mr. Norell filed in April 2023, a Form 3 and Form 4 for Ms. Reich filed in November 2023 and December 2023, respectively, , a Form 4 for Mr. Savino filed in August 2023, Forms 4 for Mr. Concannon, Mr. Peretz, Ms. Brink and Ms. Detrick filed in December 2023. Each such late filing was the result of administrative error. Value Act Holdings additionally filed a late Form 4 in May 2023.

IMPORTANT NOTICE REGARDING THE INTERNET AVAILABILITY OF PROXY MATERIALS
FOR THE ANNUAL MEETING

The SEC’s e-proxy rules require companies to post their proxy materials on the Internet and permit them to provide only a Notice of Internet Availability of Proxy Materials to stockholders. On or about April 11, 2024, we will begin mailing such Notice to all stockholders entitled to vote at the Annual Meeting informing them that our Proxy Statement, Annual Report and voting

49

instructions are available online. As more fully described in that Notice, all stockholders may choose to access our proxy materials on the Internet or may request to receive paper copies of the proxy materials. Our Proxy Statement for the Annual Meeting, Proxy Card and Annual Report are available at https://investors.altuspower.com

50

HOUSEHOLDING OF PROXY MATERIALS

SEC rules concerning the delivery of annual disclosure documents allow us or your broker to send a single set of our proxy materials to any household at which two or more of our stockholders reside, if we or your broker believe that the stockholders are members of the same family, unless we have received contrary instructions from one or more of the stockholders. This practice, referred to as “householding,” benefits both you and us. It reduces the volume of duplicate information received at your household and helps to reduce our expenses. The rule applies to our notices, annual reports, proxy statements and information statements.

We undertake to deliver promptly, upon written or oral request, a separate copy to a stockholder at a shared address to which a single copy of proxy materials was delivered. You may make a written or oral request by sending a notification to the Corporate Secretary at the address above, providing your name, your shared address, and the address to which we should direct the additional copy of proxy materials. Multiple stockholders sharing an address who have received one copy of a mailing and would prefer us to mail each stockholder a separate copy of future mailings should contact us at our principal executive offices. Additionally, if current stockholders with a shared address received multiple copies of a mailing and would prefer us to mail one copy of future mailings to stockholders at the shared address, notification of that request may also be made through our principal executive offices. Stockholders who participate in householding will continue to have access to and utilize separate proxy voting instructions.
