Dear Fellow Stockholders:

We invite you to join us and our Board of Directors at our 2026 Annual Meeting of Stockholders, which will be held at 10:00 a.m. Eastern Time on Wednesday, May 20, 2026. The meeting will be held in a virtual format via audio webcast only. Stockholders will not be able to attend the Annual Meeting physically but will be able to vote and submit questions online before and during the meeting.

At this year's meeting we will vote on the election of 12 directors, the ratification of Ernst & Young LLP as the Company's independent auditor and the adoption of a new equity incentive plan to replace our existing plan, which will expire next year. We will also conduct a non-binding, advisory vote to approve the compensation of the Company's named executive officers.

Your vote at the upcoming Annual Meeting is important. Whether or not you plan to attend the meeting, we want your shares to be represented. Please authorize a proxy to vote your shares as soon as possible. You can do so on a dedicated website, by telephone, or by completing, signing and returning the proxy card or voting instruction form enclosed with the Proxy Statement (if you received a printed copy of the proxy materials). For more detailed instructions on how to vote and attend the virtual meeting audio webcast, as well as how to submit questions before and during the meeting, see the questions and answers beginning on page 88 of the Proxy Statement.

Our Board of Directors values your participation as a stockholder and appreciates your continued support of AvalonBay.

## Proposal 1. Election of Directors
The Board of Directors (which we refer to as the "Board") currently consists of 12 members. All of the current directors are nominated for re-election at the Annual Meeting. If elected, these 12 nominees will serve until the 2027 Annual Meeting of Stockholders and until their successors are elected and qualify. The Board anticipates that each of the nominees, if elected, will serve as a director. However, if any nominee is unable to serve or chooses not to serve, proxies will be voted for the election of such other person as the Board may recommend. You may not vote for more than 12 directors at the Annual Meeting.

Required Vote and Recommendation

Only holders of record of AvalonBay's common stock as of the close of business on March 23, 2026 (the "Record Date") are entitled to vote on this proposal. Proxies will be voted for all of the nominees unless contrary instructions are set forth on a properly executed proxy card. Under our Bylaws, a majority of the total votes cast as to each nominee is required to elect such nominee. Under Maryland law, abstentions and broker non-votes are not treated as votes cast and will have no effect on the result of the vote.

Information

The NGCR and the full Board are focused on ensuring that the composition of the Board continues to provide the diversity of background, experience, functional skills, expertise, and thought necessary to appropriately address the needs of AvalonBay and our stockholders.

The following table summarizes certain qualifications, skills and experiences of each director that the Board considered important in its decision to re-nominate that individual to the Board. Exclusion of a factor for a nominee does not necessarily mean the nominee does not possess that attribute. It means only that when the NGCR considered skills and experiences in the overall context of the members of the Board, certain attributes were not considered critical with respect to certain individuals.

## Corporate Governance

### Independence of the Board
The New York Stock Exchange ("NYSE") has adopted independence standards for companies listed on the NYSE, which apply to AvalonBay. These standards require a majority of the Board to be independent and every member of the Audit Committee, Compensation Committee and NGCR to be independent. NYSE standards provide that a director is considered independent only if the Board "affirmatively determines that the director 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)." In addition, the NYSE prescribes certain other "independence" standards.

To determine which of its members is independent, the Board uses the standards prescribed by the NYSE and also considers whether a director had any other past or present relationships with AvalonBay that created conflicts or the appearance of conflicts. Based on its most recent review, the Board affirmatively determined that all directors who served on the Board during 2025, all currently serving directors and all nominees for director are independent, except in each case for Mr. Naughton and Mr. Schall.

Our Board has made a determination as to each independent director that no relationship exists which, in the opinion of the Board, would interfere with the exercise of the director's independent judgment in carrying out his or her responsibilities as a director. In making these determinations, our Board reviewed and discussed information provided by the directors and the Company regarding each director's business and personal activities as they may relate to the Company, its management and/or its independent registered public accounting firm.

NYSE rules provide for additional independence standards that apply to members of the Audit Committee and the Compensation Committee. The Board has determined that each current and proposed member of these committees satisfies these additional standards.

### Leadership Structure and Lead Independent Director
Timothy J. Naughton serves as AvalonBay's non-executive Chairman of the Board. Mr. Naughton previously served for many years as the Company's Chief Executive Officer. He served as Executive Chairman throughout 2022 and retired from being an officer of the Company on January 1, 2023, continuing as non-executive Chair. Our current CEO, Benjamin W. Schall, joined the Company in 2021 and became CEO on January 3, 2022. Mr. Naughton's role as Chairman of the Board, working with the Lead Independent Director, assures continuity of leadership at the Board level while strengthening the bridge between the Board, our Chief Executive Officer, and management.

To help ensure sound corporate governance practices, the Board established the position of Lead Independent Director. Mr. Brown has served as the Lead Independent Director since May 2023. The Lead Independent Director presides at all meetings of the Board at which the Chairman is not present, serves as a liaison between the Chairman of the Board and/or the Chief Executive Officer, on the one hand, and the independent directors, on the other, reviews or establishes, and approves, meeting agendas for the Board, has the authority to call meetings of the independent directors, confers with the Chairman of the Board and the Chief Executive Officer regularly, and acts as a contact person for stockholders and others who wish to communicate with the independent directors.

### Succession Planning for Directors and Board Refreshment
The Board considers a variety of factors when choosing candidates for Board appointment or nomination. While we value long-tenured directors with significant institutional knowledge of AvalonBay and its operations, the Board also believes it is important to ensure there are regular opportunities for new directors who may bring fresh perspective, relevant experiences, and skills that align with our long-term strategy. Consistent with this philosophy, we have recruited four new independent directors to join the Board in the past five years as part of a deliberate board refreshment process.

AvalonBay's Corporate Governance Guidelines incorporate term expectations that reflect the Board's view of the importance of succession planning. Specifically, the Corporate Governance Guidelines express an expectation that (i) an independent director will not be re-nominated after completing 12 full years of service or within the several years that follow; (ii) the Lead Independent Director will serve in that role for approximately three to five years; and (iii) committee chairs will serve for approximately three to five years. In each case, the guideline is flexible and the exact timing for any transition will depend on the needs of the Board at the time and whether an appropriate successor has been identified and nominated.

### Evaluation and Nomination of Director Candidates
One of the key functions of the NGCR is identifying and nominating candidates for service on the Board. In this regard, the NGCR considers the factors set forth in the Corporate Governance Guidelines, which include the nominee's business and professional background; history of leadership or contributions to other organizations; functional skill set and expertise; general understanding of marketing, finance, accounting and other elements relevant to the success of a publicly-traded company; and service on other boards of directors. Given the current business, opportunities and challenges confronting our industry, the NGCR pays particular attention to the skills and experience described in the Director Skills/Experience Matrix provided above.

When recommending a slate of nominees for director and identifying new candidates for service, the NGCR considers whether the Board as a whole has and will continue to have an adequate distribution and representation of relevant skills, backgrounds and experience. In addition to professional history and expertise, the Board may consider diversity of background, skills, experience and thought in evaluating and recommending candidates for election. The Board believes that diversity is important because a variety of points of view can contribute to a more effective decision-making process.

The NGCR may employ a variety of methods for identifying and evaluating nominees for director. In considering whether to recommend re-nomination of a current director for another term, the NGCR considers whether the skills, commitment and performance of the individual director are such that the individual's continued service on the Board is desirable. The NGCR also may assess the size of the Board, the need for particular expertise, and whether any vacancies are expected, due to retirement or otherwise.

The NGCR will consider potential candidates for director who come to the committee's attention through current Board members, professional search firms, stockholders or other sources. When compiling a pool of candidates to review and interview for a new director search, the NGCR endeavors to include, and requests that any search firm it engages endeavor to include, candidates with a diversity of race, ethnicity and gender. AvalonBay has in the past engaged and may in the future engage a third party firm to help identify and/or evaluate potential director nominees.

Nominees Recommended by Stockholders

The NGCR will consider candidates properly recommended by stockholders using the same criteria that apply to candidates from other sources. Following verification of the stockholder status of the party or parties proposing a candidate, the NGCR makes an initial analysis of the candidate's qualifications based on the criteria summarized above to determine whether the candidate is suitable for service on the Board before deciding whether to undertake a complete evaluation of the candidate. If a stockholder provides any materials in connection with the nomination of a director candidate, such materials are forwarded to the NGCR as part of its review. The Board may also consider the specific information required to be provided by nominating stockholders pursuant to the requirements of AvalonBay's Bylaws. Stockholders may also nominate directors in accordance with the proxy access provisions of AvalonBay's Bylaws. For more information on stockholder nominations, see "Other Matters—Stockholder Nominations for Directors and Proposals for Annual Meetings."

### Board of Directors Risk Management Oversight
We have a number of practices with regard to Board oversight of risk management matters. The charter of each Board committee provides that the committee will, from time to time and to the extent the committee deems appropriate, review risk and compliance matters relevant to the committee and report the results of such review to the full Board. As required by NYSE rules, the charter of the Audit Committee states that the Audit Committee will assist with Board oversight of risk and compliance matters, and in any event will review AvalonBay's perceived major financial risk exposures and the steps management has taken to monitor and control such exposures. At most regularly scheduled Board meetings, the Board reviews key matters relating to AvalonBay's finances, liquidity, operations and investment activity. On an annual basis, the Board and/or the Audit Committee engages in a broader discussion about Company-wide risk management.

The Audit Committee (and on occasion the full Board in lieu of the Audit Committee) also reviews matters related to cybersecurity. The Board has delegated primary oversight of cybersecurity risks to the Audit Committee, including those related to data privacy and network security. The Audit Committee's charter provides that the Audit Committee will meet no less frequently than annually with personnel from the Company's information technology group and senior management to discuss the Company's strategy and standards to defend its IT networks, business systems and information against cyber-attacks, cyber intrusions, unauthorized disclosures of personally identifiable information or Company data, and similar disruptions, and senior management also provides periodic reports to the Audit Committee and/or the full Board in addition to this annual requirement. The Audit Committee also has oversight responsibility of management's preparedness for and response to any cybersecurity incidents and, in connection therewith, the Audit Committee may retain consultants and advisors and take and approve other actions and expenditures as deemed reasonable and appropriate by the Audit Committee. The Company has not experienced any material cybersecurity incidents to date. For additional information regarding the Company's cybersecurity risk management, strategy and governance, see Item 1C. "Cybersecurity" of the Company's Annual Report on Form 10-K for the year ended December 31, 2025 (the "Form 10-K"), as filed with the Securities and Exchange Commission (the "SEC") on February 27, 2026.

Although it is not the primary reason the Board's current leadership structure was implemented, AvalonBay and the Board believe the current leadership structure—including both a Chairman of the Board and a separate Lead Independent Director—helps facilitate these risk oversight functions by providing multiple channels for risk-related concerns and comments.

### Stockholder Engagement and Responsiveness
We consider our relationship with our stockholders to be an important part of AvalonBay's success and we value the outlook and opinions of our investors. Each year, our management and, in some instances, certain of our independent directors, engage with stockholders to discuss our practices and policies with respect to board governance, compensation, corporate responsibility and other matters. These discussions may address matters such as Board composition and refreshment, stockholder rights, the structure for executive compensation, sustainability efforts and other strategic and governance topics. Feedback received from these engagements is conveyed to and discussed with the full Board and relevant committees. These conversations help to ensure that management and the Board understand and consider the issues that are most important to our stockholders and to enable AvalonBay to address them effectively.

In addition to conversations with our stockholders, AvalonBay management occasionally receives and responds to correspondence from stockholders and stockholder advocacy groups and, when appropriate, shares this correspondence with the NGCR and the full Board. The Board also considers the votes of stockholders at our Annual Meeting and discusses potential issues raised through that forum.

### Board and Committee Self-Evaluation
Each year the Board conducts a self-evaluation in which the Lead Independent Director talks to each director individually regarding his or her view of how the Board overall and each of our directors is performing and the effectiveness of the Board's processes and governance practices. Topics discussed may include whether there are additional items that should be added to agendas, whether management is providing the Board with the information it needs to effectively review AvalonBay's performance and risks, whether meetings feature a healthy level of debate and participation, whether the composition of the Board is appropriate, whether the Board is adequately monitoring AvalonBay's strategic direction, and the performance and development of management. This feedback is then discussed in an executive session of the Board.

In addition, each of the Board's committees annually conducts a review of its charter and a self-assessment of the performance of committee duties under its charter over the previous year. The review generally includes the role of the committee within AvalonBay, the committee's structure and functioning, and the committee's charter and fulfillment of delegated responsibilities.

### Human Capital Management
Our purpose as a company is to create a better way to live, and all AvalonBay associates, from those based at our communities to those at our regional and corporate offices, have a role to play in bringing our purpose to life.

We believe that AvalonBay's culture is a differentiator that leads to success in fulfilling our purpose. Our company culture centers around our core values and cultural norms, which are touchstones that help guide our behavior and decision-making and support associate engagement.

As of January 31, 2026, we had 3,041 employees, of which approximately 99% were employed on a full-time basis. Approximately 61% of our associates work on-site at our operating communities. At January 31, 2026, 36% of our associates self-identified as White, 30% as Hispanic, 17% as Black, 7% as Asian, and 10% as other ethnicities, two or more ethnicities or did not respond. At January 31, 2026, 60% of our associates self-identified as male and 40% as female. We publish our latest EEO-1 report on our public Corporate Responsibility website.

At AvalonBay we believe that our associates are our most important resource and support their professional development and career advancement. To support their progress, our managers and associates have ongoing performance and career development conversations and memorialize them in a year-end performance review and development goals. We train and develop our associates in a variety of ways, including online, instructor-led and on-the-job learning. Our learning management system, Workday Learning, offers approximately 700 courses providing functional, technical, management, ethics, compliance, cyber-awareness and safety training. In addition, our tuition assistance program supports our associates by providing them with reimbursement, subject to program rules and limitations, for undergraduate and graduate degree programs or for coursework leading to professional certifications/designations. We also support leadership development and succession planning across key operational and corporate roles.

Each year we conduct an Associate Perspective Survey, which enables AvalonBay to better understand how associates view the Company, their managers, and their overall experience. Based on the survey results, we endeavor to improve in areas that are deemed by associates as opportunities for growth. The 2025 survey showed that associate engagement was maintained at strong levels, consistent with the prior year.

We prioritize workplace safety across our operating communities, construction sites, and offices, and we strive to maintain a positive safety culture and work environment for all associates. To support this, our associates complete regular safety training courses on a variety of topics, and our risk management group tracks incident reports across our operations. Additionally, the safety department leads a Safety Committee, which continually evaluates and improves our safety programs. We monitor our operational safety performance through monthly maintenance checkups and our construction safety performance through our Site Safety Observation program. Our safety team closely tracks project-level safety metrics at construction sites, and construction safety compliance is tied to compensation for both our construction team and CEO.

The Board, through its Compensation Committee, reviews management's human resources practices, including talent management and training. The NGCR reviews matters related to inclusive work practices and our workforce inclusion and diversity. The Board actively supports activities that encourage an inclusive culture at AvalonBay and receives periodic updates regarding human capital matters.

Additional information on each of these areas relating to human capital management can be found under the "About Us – Corporate Responsibility" section of our website at www.avalonbay.com. Materials located on AvalonBay's website and referenced herein are not deemed to be part of this Proxy Statement and are not incorporated herein by reference.

### Transactions with Related Persons, Promoters and Certain Control Persons
Our Code of Business Conduct and Ethics prohibits employees, including executive officers and directors, from engaging in activities that create a conflict of interest with AvalonBay unless all relevant details have been disclosed and an appropriate mitigation or waiver permitting the conduct has been received. An activity constitutes a conflict of interest under the Code if (i) the activity could adversely affect or compete with AvalonBay, (ii) any interest, connection or benefit to the employee or director from the activity could reasonably be expected to cause such employee or director to consider anything other than the best interest of AvalonBay when deliberating and voting on Company matters, (iii) any interest, connection or benefit to the employee or director from the activity could give such employee or director or a member of his or her family or other closely related individuals an improper benefit that was obtained on account of his or her position within AvalonBay, or (iv) the employee or director is placing his or her own interests above the Company's interest. Mitigations and waivers for executive officers or directors may only be granted by the Board or a designated committee of the Board, and any mitigation or waiver granted to an executive officer or director will be disclosed to the extent required by law or NYSE rules. The NGCR (or any other committee of independent directors that is designated) is responsible for overseeing the administration of the Code for executive officers and directors.

The Board has also adopted a written policy relating to the review, approval and ratification of transactions with related persons. The policy applies to any transaction required to be disclosed by the Company pursuant to Item 404 of Regulation S-K (or any successor provision) promulgated by the SEC. Generally, unless the transaction is one that is pre-approved under the related party transaction policy, prior to entering into a related party transaction the Company must submit the proposed transaction (along with appropriate background information) for review by the NGCR (or a subcommittee of the NGCR). In deciding whether to approve the transaction, the NGCR (or subcommittee) will take into account, among other factors that it deems appropriate, whether the transaction is on terms no less favorable to the Company than terms generally available in a transaction with an unaffiliated third-party under the same or similar circumstances, whether the transaction is otherwise consistent with the interests of the Company and its stockholders, and the extent of the related person's interest in the transaction.

### Director Compensation
The compensation for our non-employee directors is described below. Directors who are also employees do not receive additional compensation for serving on the Board. Our Board and NGCR periodically assess the total compensation for non-employee directors relative to the compensation provided by similarly sized REITs, by our multifamily peer group, and by a group of cross-industry similarly-sized companies. Following its most recent review, the Board approved additional annual retainers for non-employee directors serving on Board committees, effective for service commencing following the 2026 Annual Meeting, as shown in the table below.

| Annual retainer | $100000 | $100000 | Quarterly installments, in cash or, at the director's election, in the form of deferred stock units |
| Additional retainer for Committee membership (per committee) | $0 | $7500 | Quarterly installments, in cash or, at the director's election, in the form of deferred stock units |

| Additional retainer for Audit Committee chair | $30000 | $30000 | Quarterly installments, in cash or, at the director's election, in the form of deferred stock units |
| Additional retainer for Compensation Committee chair | $25000 | $25000 | Quarterly installments, in cash or, at the director's election, in the form of deferred stock units |
| Additional retainer for chairs of the Investment and Finance Committee and the Nominating, Governance and Corporate Responsibility Committee | $20000 | $20000 | Quarterly installments, in cash or, at the director's election, in the form of deferred stock units |
| Additional retainer for Lead Independent Director | $50000 | $50000 | Quarterly installments, in cash or, at the director's election, in the form of deferred stock units |
| Additional retainer for Non-Executive Chairman | $250000 | $250000 | Quarterly installments, in cash or, at the director's election, in the form of deferred stock units |

---

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *Share and unit awards are determined based on the dollar values described above and the closing stock price on the date of grant, rounded to the nearest whole number.* 

The annual equity retainer granted to non-employee directors in the form of shares of restricted stock (or deferred stock units) vests in four quarterly installments over a one-year period, subject to accelerated vesting upon departure from the Board except in the case of a voluntary departure by the director during the director's elected term that is not due to death or disability or the director's removal for cause. If a director elects to receive deferred stock units in lieu of restricted stock, the director will receive shares of stock in respect of the vested portion of the deferred stock units following termination of service as a director. For deferred stock units, dividends equivalent to the dividends paid on shares of common stock are "reinvested" and credited in the form of additional deferred stock units.

### Director Stock Ownership Guidelines
Under our Corporate Governance Guidelines, non-employee directors are generally required to hold shares (or deferred stock units) having a value that equals or exceeds five times the annual cash retainer paid to non-employee directors. Directors have five years from the commencement of their service as a director to comply with such requirement. As of April 1, 2026, all the non-employee directors who have served on the Board for five years or more were in compliance with this requirement.

## Proposal 2. Non-Binding, Advisory Resolution to Approve Executive Compensation
Section 14A(a)(1) of the Exchange Act generally requires each public company to include in its proxy statement a non-binding, advisory resolution subject to stockholder vote to approve the compensation of the Company's named executive officers. The Compensation Discussion and Analysis as presented below describes AvalonBay's executive officer compensation program and decisions made by the Compensation Committee and the Board with respect to the 2025 compensation of our named executive officers. We believe the compensation program achieves our goals of (i) attracting, retaining, motivating and engaging experienced and effective executives, (ii) aligning the interests of management with the interests of our stockholders, (iii) aligning pay with performance, with clearly defined goals and measures of achievement, and (iv) focusing on total compensation, consisting of base salary and incentive compensation.

We have held a non-binding, advisory vote on the compensation of our NEOs (known as a "Say-on-Pay Vote") at each Annual Meeting of Stockholders since 2011. At our 2023 Annual Meeting of Stockholders, our stockholders voted on a proposal regarding the frequency of holding a Say-on-Pay Vote, among other matters. A majority of the votes cast on the frequency proposal were cast in favor of holding a Say-on-Pay Vote every year, which was consistent with the recommendation of our Board. Our Board currently intends for the Company to hold a Say-on-Pay Vote every year at least until the 2029 Annual Meeting of Stockholders, which is the next required non-binding, advisory vote on the frequency of holding a Say-on-Pay Vote. At that meeting we plan to hold an advisory vote regarding the frequency of future Say-on-Pay Votes.

While the vote on the following resolution is advisory and will not bind us to take any particular action, our Compensation Committee and our Board will carefully consider the stockholder Say-on-Pay Vote in making future decisions regarding our compensation program. The Board is asking stockholders to adopt the following resolution:

"RESOLVED, that the compensation paid to AvalonBay's named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, compensation tables and any related material disclosed in this Proxy Statement, is hereby APPROVED, on a non-binding, advisory basis, by the stockholders of AvalonBay."

Required Vote and Recommendation

Only holders of record of AvalonBay's common stock as of the close of business on the Record Date are entitled to vote on this proposal. Proxies will be voted for adoption of the resolution approving the compensation disclosed unless contrary instructions are set forth on the proxy card. A majority of the votes cast on the proposal at the Annual Meeting is required to provide non-binding, advisory approval of the compensation paid to AvalonBay's named executive officers. Under Maryland law, abstentions and broker non-votes are not treated as votes cast. Accordingly, an abstention or broker non-vote will have no effect on the result of the vote.

## Proposal 3. 2026 Equity Incentive Plan
Stockholders are being asked to approve AvalonBay's 2026 Equity Incentive Plan (the "2026 Plan"), a new stockholder-approved plan that will be the primary vehicle for granting equity awards to eligible employees, directors, and other service providers. If the 2026 Plan is approved, the Company will cease to issue any new grants under its existing Second Amended and Restated 2009 Equity Incentive Plan (the "Amended 2009 Plan"), which was last approved by stockholders in 2017 and is nearing its expiration date. All new awards granted following stockholder approval will be made under the 2026 Plan.

On February 26, 2026, the Board, upon the recommendation of the Compensation Committee, approved the 2026 Plan. The effective date of the 2026 Plan will be the date of stockholder approval; for ease of exposition, in the discussion below it is assumed that the 2026 Plan is approved on, and therefore the effective date of the 2026 Plan will be, the date of the Annual Meeting: May 20, 2026.

A copy of the 2026 Plan is attached as Appendix II to this proxy statement and is incorporated herein by reference**.**

Required Vote and Recommendation

Only holders of record of common stock as of the close of business on the Record Date are entitled to vote on this proposal. Proxies will be voted for approval of the AvalonBay Communities, Inc. 2026 Equity Incentive Plan unless contrary instructions are set forth on the enclosed proxy card. This proposal requires the affirmative vote of a majority of all of the votes cast on the matter. Under Maryland law, abstentions and broker non-votes are not treated as votes cast. Accordingly, an abstention or broker non-vote will have no effect on the result of the vote.

### Why Approve the 2026 Plan?
● **The current Amended 2009 Plan was last approved by stockholders in 2017 and is set to expire on May 15, 2027,** after which no additional awards may be granted thereunder. If the 2026 Plan is adopted, no additional awards will be issued under the Amended 2009 Plan. By adopting the 2026 Plan at the Annual Meeting ahead of the scheduled expiration of the Amended 2009 Plan, the Company will be better able to plan for its compensation program.

● **Equity aligns pay with performance & stockholders:** Equity is a core element of our long-term incentive program and aligns employees' and directors' interests with stockholders by emphasizing long-term value creation.

● **Talent attraction and retention:** In competitive labor markets, equity awards are a critical tool for recruiting and retaining key talent across levels and geographies and supporting succession planning across the organization.

● **Our 2026 Plan contains stockholder friendly provisions:** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o No stock option or stock appreciation rights ("SAR") repricing without stockholder approval

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o No discounted options/SARs or reload options

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Transparent share counting provision

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o One-year minimum vesting for employee awards, with limited exceptions as described in the plan document

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Robust clawback provision

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Responsible change of control provisions

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Fixed share cap with no evergreen feature

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o No payment of cash dividends on unearned performance awards

Requested Share Authorization & Share Pool Design

**Share Reserve:** We are requesting authorization of 4,000,000 shares of common stock for issuance under the 2026 Plan (the "Share Reserve"). The Share Reserve is a fixed cap with no "evergreen" automatic increases. No shares from the Amended 2009 Plan will roll over. However, if an award issued under the 2026 Plan or Amended 2009 Plan is forfeited, cash-settled or expires unexercised or unearned (such as unvested restricted shares that are forfeited, stock options that expire unexercised, or shares underlying performance awards that are unearned), the shares subject to such award will be available for future issuance under the 2026 Plan. If any shares are granted after March 15, 2026, the shares will count towards the 2026 Plan (assuming the 2026 Plan is approved by stockholders).

In determining the number of proposed shares issuable under the 2026 Plan, the Compensation Committee and the Board considered a number of factors, including historical equity award grant practices, reasonable expected dilution compared to other S&P 500 REITs, and projected share usage.

**Transparent Share Counting:** Shares used to pay exercise prices or withholding taxes for options/SARs will not return to the pool; net-settled SARs also do not recycle.

**Plan Term**: No awards may be granted more than 10 years after the date of stockholder approval.

Key Data— Potential Dilution

The table below summarizes the potential dilution based on the proposed new share request and outstanding awards as of March 15, 2026 (which is after our February 26, 2026 annual equity awards and March 1, 2026 vesting of annual equity awards and settlement of 2023-2025 performance awards):

| | | |
|:---|:---|:---|
| **Component (As of March 15, 2026)** | **Total Shares** | **Basic Dilution**<sup>(1)</sup> |
| A.<br>Stock Options Issued and Outstanding <sup>(2)</sup><br>| 294892 | 0.21% |
| B. Restricted Stock Outstanding | 191066 | 0.14% |
| C. Performance Shares Outstanding (at Target) | 262887 | 0.19% |
| D. Restricted Stock Units Outstanding | 100542 | 0.07% |
| **Total Stock Awards Outstanding (A+B+C+D)** | 849387 | 0.61% |
| E. Reserved for New Awards if 2026 Equity Incentive Plan is approved on May 20, 2026 <sup>(3)</sup> | 4000000 | 2.87% |
| F. Available Shares under Amended 2009 Plan on May 15, 2026<br>Note: If the 2026 Plan is approved, no additional shares will be issued under the Amended 2009 Plan following such approval | 0 | 0.00% |
| **G. Total New Awards + Total Stock Awards Outstanding (A+B+C+D+E+F)** | 4849387 | 3.48%  |

---

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *In each case, numerator equals the number of awards shown in the row and denominator equals the number of common shares outstanding on March 15, 2026 of 139,258,978.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(2)* *For options outstanding as of March 15, 2026, the weighted average exercise price is $182.99 and the weighted average contractual life is 5.72 years.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(3)* *If any shares are granted after March 15, 2026, the shares will count towards the 2026 Plan (assuming the 2026 Plan is approved by stockholders).* 

The proposed basic dilution of 3.48% is reasonable, which will support AvalonBay's pay for performance philosophy and will align with stockholders' interests.

Key Data— Share Usage—Historical Burn Rate

The "annual burn rate" is one measure of how fast a company uses the supply of shares authorized for issuance under its stock plan. The following table sets forth our historic use of equity during the years ended December 31, 2023, 2024 and 2025, which demonstrates our responsible use of stock-based compensation:

|  |  |  |  |  | **Three-year Average** | **Three-year Average** | **0.16%** |

---

**Expected Duration of Share Reserve:** Based on our historical and projected usage, the requested Share Reserve is expected to last through the expiration of the 2026 Plan, subject to factors like stock price, participation, grant mix/levels, hiring, forfeitures, and compensation practice changes.

**Historical Award Recipients and Award Types:** The 2026 Plan provides a variety of equity and equity-based awards, including stock options, performance awards, restricted stock and restricted stock units. Our awards generally consist of restricted stock and performance shares to eligible employees. The Board of Directors may elect to receive their annual retainers or quarterly cash retainers in restricted stock or restricted stock units .

Governance & Plan Design Highlights

● **No option/SAR repricing** (including cash buyouts or exchange for lower-priced awards) without stockholder approval. Repricing of stock options and SARs and cash buyouts of underwater stock options and SARs is prohibited without stockholder approval.

● **Transparent share counting.** The 2026 Plan does not allow for reuse of shares tendered, exchanged or withheld to cover option exercise costs, any award shares withheld to cover taxes, or shares underlying an award of stock appreciation rights once such stock appreciation rights are exercised.

● **Minimum vesting**: equity awards generally vest no earlier than one year, subject to limited exceptions under which no more than five percent of the Share Reserve may be granted with less than the minimum one-year vesting.

● **Dividends are paid on earned performance awards,** and no dividends are paid on stock options.

● **Double trigger Change-in-Control ("CIC")** where there is no automatic vesting upon a CIC and restricted stock awards accelerate only if not assumed/substituted or upon qualifying termination within 24 months post-CIC; performance awards settle at target upon CIC.

● Awards are subject to **clawback** under the Company's Compensation Recovery Policy.

### Summary of the Material Terms of the 2026 Plan
The following description of certain features of the 2026 Plan is intended to be a summary only. The summary is qualified in its entirety by the full text of the 2026 Plan that is attached hereto as Appendix II.

Administration

The Compensation Committee, consisting entirely of independent directors, will administer the 2026 Plan, including selecting participants; determining award types, sizes, and terms; interpreting the 2026 Plan; and making all necessary determinations. The Compensation Committee may delegate to our Chief Executive Officer (or other executive officers) the authority to grant awards to employees who are not subject to the reporting and other provisions of Section 16 of the Securities Exchange Act of 1934 (the "Exchange Act") and not a Covered Employee under Section 162(m) of the Code, subject to certain limitations and guidelines.

Eligibility

Persons eligible to participate in the 2026 Plan will be those full-time officers, employees, non-employee directors and other key persons of the Company and its subsidiaries as selected from time to time by the Compensation Committee in its discretion. As of the date of this proxy statement, the Company has approximately 3,000 employees, approximately 75 of whom are officers, and eleven non-employee Board directors. With respect to Company associates, the Company's recent practice has been to generally make equity incentive awards to associates who have attained the title of officer, senior director or (in field offices) director; approximately 140 associates are eligible to receive awards pursuant to this practice.

Stock Options

The 2026 Plan permits the granting of (1) options to purchase common stock intended to qualify as incentive stock options under Section 422 of the Code and (2) options that do not so qualify. No more than 2,000,000 shares will be issued in the form of incentive stock options. Options granted under the 2026 Plan will be non-qualified options if they fail to qualify as incentive options or exceed the annual limit on incentive stock options. Incentive stock options may only be granted to employees of the Company and its subsidiaries. Non-qualified options may be granted to any persons eligible to receive incentive options and to non-employee directors and key persons. The option exercise price of each option will be determined by the Compensation Committee but may generally not be less than 100% of the fair market value of the common stock on the date of grant. Fair market value for this purpose will be the last reported sale price of the shares of common stock on the NYSE on the date of grant. The exercise price of an option may not be reduced after the date of the option grant, other than to appropriately reflect changes in our capital structure.

The term of each option will be fixed by the Compensation Committee and may not exceed ten years from the date of grant.

Stock Appreciation Rights

The Compensation Committee may award stock appreciation rights subject to such conditions and restrictions as the Compensation Committee may determine. Stock appreciation rights entitle the recipient to shares of common stock equal to the value of the appreciation in the stock price of a designated number of shares of our common stock over the exercise price. The exercise price is the fair market value of the common stock on the date of grant.

Restricted Stock

The Compensation Committee may award shares of common stock to participants subject to such conditions and restrictions as the Compensation Committee may determine. These conditions and restrictions may include the achievement of certain performance goals and/or continued employment with us through a specified restricted period.

Restricted Stock Units

The Compensation Committee may award restricted stock units to any participants. Restricted stock units are ultimately payable in the form of shares of common stock and may be subject to such conditions and restrictions as the Compensation Committee may determine.

[**Table of Contents**](#TOC)

These conditions and restrictions may include the achievement of certain performance goals and/or continued employment with the Company through a specified vesting period. In the Compensation Committee's sole discretion, it may permit a participant to make an advance election to receive a portion of his or her future cash compensation or other Award otherwise due in the form of a restricted stock unit award, subject to the participant's compliance with the procedures established by the Compensation Committee and requirements of Section 409A of the Code. During the deferral period, the deferred stock awards may be credited with dividend equivalent rights.

Unrestricted Stock Awards

The Compensation Committee may also grant shares of common stock which are free from any restrictions under the 2026 Plan. Unrestricted stock may be granted to any participant in recognition of past services or other valid consideration and may be issued in lieu of cash compensation due to such participant. However, any such grant of restricted stock that is made to employees must comply with the limitation that no more than 5% of the awards reserved and available for issuance as of May 20, 2026 may, in total, be issued without regard to the minimum one-year vesting period.

Performance Share Awards

The Compensation Committee may grant performance share awards to any participant which entitle the recipient to receive shares of common stock upon the achievement of certain performance goals and such other conditions as the Compensation Committee shall determine. Currently, our performance awards have a three-year performance period.

Dividend Equivalent Rights

The Compensation Committee may grant dividend equivalent rights to participants which entitle the recipient to receive credits for dividends that would have been paid if the recipient had held specified shares of common stock. Dividend equivalent rights may be granted as a component of another award (other than a stock option or stock appreciation right) or as a freestanding award. Dividend equivalent rights may be settled in cash, shares of common stock or a combination thereof, in a single installment or installments, as specified in the award.

Other Equity-Based Awards

The Compensation Committee may grant awards of units in an affiliate of the Company, including LTIP units and AOLTIP units, which may be convertible into, exchangeable for or redeemable into shares of Common Stock. Such units may be issued subject to vesting requirements, which, if they are not met, may result in the automatic forfeiture of any such units issued. LTIP units and AOLTIP units are intended to qualify as "profits interests" for U.S. federal income tax purposes, and AOLTIP units are intended to be similar to stock options from an economic perspective. Like stock options, AOLTIP units operate in a manner that generally permits holders to realize the benefit of any increase in the per share value of our Common Stock above the value at the time the AOLTIP units are granted.

Cash-Based Awards

The Compensation Committee may grant cash bonuses under the 2026 Plan to participants. The cash bonuses may be subject to the achievement of certain performance goals. However, as cash-based awards, any such cash bonuses will not reduce the number of shares of common stock available for issuance under the 2026 Plan.

Sale Event

The 2026 Plan provides that upon the effectiveness of a "sale event" as such term is defined in the 2026 Plan, and except as otherwise provided by the Compensation Committee in an award agreement, all awards will be terminated unless the parties agree to assume or continue the awards with appropriate adjustments. In the event that awards are assumed, continued or substituted in connection with a Sale Event, then the award will become fully vested and nonforfeitable in the event that the grantee's employment or other business relationship with the Company is terminated (i) by the Company without cause or (ii) by the grantee for Good Reason, in either case in connection with or within 24 months following the Sale Event, except as may otherwise be provided in the relevant award agreement. In case awards are not assumed, the Company may make or provide for a cash payment to participants holding options and stock

[**Table of Contents**](#TOC)

appreciation rights equal to the difference between the per share cash consideration and the exercise price of the options or stock appreciation rights.

Adjustments for Stock Dividends, Stock Splits, Etc.

The 2026 Plan requires the Compensation Committee to make appropriate adjustments to the number of shares of common stock that are subject to the 2026 Plan, and to any outstanding awards and/or to the price for each share of common stock subject to outstanding awards of stock options and stock appreciation rights to reflect stock dividends, stock splits, extraordinary cash dividends and similar events.

Tax Withholding

Participants in the 2026 Plan are responsible for the payment of any federal, state or local taxes that the Company is required by law to withhold upon the exercise of options or stock appreciation rights or vesting of other awards. Subject to approval by the Compensation Committee, participants may elect to have tax withholding obligations satisfied by authorizing the Company to withhold shares of common stock to be issued pursuant to the exercise or vesting.

Amendments and Termination

The Board may at any time amend or discontinue the 2026 Plan and the Compensation Committee may at any time amend or cancel any outstanding award for the purpose of satisfying changes in the law or for any other lawful purpose. However, no such action may adversely affect any rights under any outstanding award without the holder's consent. To the extent required under the rules of the NYSE, any amendments that materially change the terms of the 2026 Plan will be subject to approval by our stockholders. Amendments shall also be subject to approval by our stockholders if and to the extent determined by the Compensation Committee to be required by the Code to preserve the qualified status of incentive options.

Effective Date of 2026 Plan

The Board adopted the 2026 Plan on February 26, 2026, and the Plan becomes effective on the date it is approved by stockholders. No awards may be granted under the 2026 Plan after May 20, 2036. If the 2026 Plan is not approved by stockholders, the plan as currently in effect will continue until it expires, and awards may be granted thereunder, in accordance with its terms.

New Plan Benefits

All awards under the 2026 Plan are made at the discretion of the Compensation Committee (or, with respect to non-employee directors, the NGCR which periodically assesses the compensation of our non-employee directors). Therefore, the future benefits and amounts that will be received or allocated to such individuals under the 2026 Plan are not determinable at this time. No awards have been made under the 2026 Plan that are contingent upon approval of the Plan by the shareholders. Consequently, no new plan benefits table is included in this proxy statement.

Tax Aspects Under the Tax Code

The following is a summary of the principal federal income tax consequences of certain transactions under the 2026 Plan. It does not describe all federal tax consequences under the 2026 Plan, nor does it describe state or local tax consequences.

*Incentive Options.* No taxable income is generally realized by the optionee upon the grant or exercise of an incentive option. If shares of Common Stock issued to an optionee pursuant to the exercise of an incentive option are sold or transferred after two years from the date of grant and after one year from the date of exercise, then (i) upon sale of such shares, any amount realized in excess of the option price (the amount paid for the shares) will be taxed to the optionee as a long-term capital gain, and any loss sustained will be a long-term capital loss, and (ii) the Company will not be entitled to any deduction for federal income tax purposes. The exercise of an incentive option will give rise to an item of tax preference that may result in alternative minimum tax liability for the optionee.

[**Table of Contents**](#TOC)

If shares of Common Stock acquired upon the exercise of an incentive option are disposed of prior to the expiration of the two-year and one-year holding periods described above (a "disqualifying disposition"), generally (i) the optionee will realize ordinary income in the year of disposition in an amount equal to the excess (if any) of the fair market value of the shares of Common Stock at exercise (or, if less, the amount realized on a sale of such shares of Common Stock) over the option price thereof, and (ii) we will be entitled to deduct such amount. Special rules will apply where all or a portion of the exercise price of the incentive option is paid by tendering shares of Common Stock.

If an incentive option is exercised at a time when it no longer qualifies for the tax treatment described above, the option is treated as a non-qualified option. Generally, an incentive option will not be eligible for the tax treatment described above if it is exercised more than three months following termination of employment (or one year in the case of termination of employment by reason of disability). In the case of termination of employment by reason of death, the three-month rule does not apply.

*Non-Qualified Options.* No income is realized by the optionee at the time the option is granted. Generally (i) at exercise, ordinary income is realized by the optionee in an amount equal to the difference between the option price and the fair market value of the shares of Common Stock on the date of exercise, and we receive a tax deduction for the same amount, and (ii) at disposition, appreciation or depreciation after the date of exercise is treated as either short-term or long-term capital gain or loss depending on how long the shares of Common Stock have been held. Special rules will apply where all or a portion of the exercise price of the non-qualified option is paid by tendering shares of Common Stock. Upon exercise, the optionee will also be subject to Social Security taxes on the excess of the fair market value over the exercise price of the option.

*Restricted Stock.* Unless a participant has made an election under Section 83(b) of the Internal Revenue Code to be taxed at grant, restricted stock is taxable as ordinary income in the taxable year in which the restrictions lapse. At that time, the participant will have taxable ordinary income and the Company will be entitled to a deduction. The amount subject to taxation (and deductible by the Company) is the fair market value of the shares reduced by any amount paid for the shares. Any accumulated dividends are also subject to taxation (and deductible by the Company) when the restrictions lapse.

*Restricted Stock Units.* RSUs are taxable to the recipient as ordinary income when the stock is payable to the recipient, even if the RSUs become non-forfeitable at an earlier date. Dividend equivalents that accumulate before the RSU is payable are paid and taxable when the RSUs become payable. The Company is not entitled to a deduction until the stock is payable.

*Other Awards.* The Company generally will be entitled to a tax deduction in connection with an award under the 2026 Plan in an amount equal to the ordinary income realized by the participant at the time the participant recognizes such income. Participants typically are subject to income tax and recognize such tax at the time that an award is exercised, vests or becomes non-forfeitable, unless the award provides for a further deferral or qualifies as a "profits interest" for U.S. federal income tax purposes.

*Parachute Payments.* The vesting of any portion of an option or other award that is accelerated due to the occurrence of a change of control may cause a portion of the payments with respect to such accelerated awards to be treated as "parachute payments" as defined in the Code. Any such parachute payments may be non-deductible to the Company, in whole or in part, and may subject the recipient to a non-deductible 20 percent federal excise tax on all or a portion of such payment (in addition to other taxes ordinarily payable).

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *Mr. Schall elected to receive 25% of his earned annual stock bonus in the form of a stock option with a total Black-Scholes value equal in amount to 25% of his earned stock bonus. The exercise price of the stock option is equal to our closing stock price on the date of grant.* 

**Cash Bonus**

Mr. Schall's target cash bonus was 175% of base salary in 2025, with 80% of the target cash bonus based on corporate performance and 20% based on individual performance. The achievement levels for corporate performance and individual factors for 2025 were determined to be 104.8% and 112.0% of target, respectively, resulting in a final cash bonus for 2025 of $1,815,540.

**Stock Bonus**

Mr. Schall's target stock bonus for 2025 was $2,100,000. The performance measures used in calculating the stock bonus reflect different elements of the Company's performance and are not duplicative of the performance measures used to evaluate corporate performance under the annual cash bonus program. Details on these performance measures can be found later in the CD&A under Annual Stock Bonus. The quantitative achievement level for these stock bonus performance measures for 2025 was 110.7% of target. This resulted in a payout of $2,296,494. Mr. Schall elected to receive 25% of the earned stock bonus value (i.e., $574,123 of the $2,296,494 award) in the form of a stock option and the remainder in the form of restricted stock. The restricted stock and stock options vest ratably over three years from the date of grant. Under applicable SEC rules, these awards will be disclosed in the 2027 proxy statement Summary Compensation Table as the actual grant of stock and options, though based on 2025 achievement, occurred in 2026.

**2025-2027 Performance Awards**

Mr. Schall's target performance award for the 2025-2027 performance period was $4,900,000, with 55% of the target award tied to relative three-year TSR metrics against REIT indices, and 45% of the target award tied to three-year financial operating metrics relative to a multifamily peer group. Additional details on Mr. Schall's 2025-2027 performance award is provided later in the CD&A.

**Settled 2023-2025 Performance Awards**

Mr. Schall's target performance award for the 2023-2025 performance period was $4,200,000. Fifty five percent (55%) of the target award was tied to relative three-year TSR metrics comparisons, and 45% of the target award was tied to three-year financial operating metrics relative to a multifamily peer group. The Compensation Committee determined achievement under the award at 134.6% of target. Mr. Schall's award was settled on February 26, 2026, in 33,996 shares of fully vested stock valued at $6,108,062 based on the closing price of the Company's common stock on the NYSE on such date of $179.67, plus a cash amount of $693,518 representing cumulative dividends accrued on the earned shares from the date of grant of the performance award through the date of its settlement.

**2025 Target Compensation**

In February 2025, the Compensation Committee approved an increase to Mr. Schall's 2025 target total compensation from $9,000,000 to $9,750,000, an increase of 8.3%, after reviewing the Company's and Mr. Schall's performance and considering other factors such as Mr. Schall's tenure in the position and compensation for CEOs at peer companies. The increase to Mr. Schall's target total compensation for 2025 was in the form of variable compensation, including target annual cash bonus, annual stock bonus and multiyear performance award. A substantial majority of Mr. Schall's target total pay is in the form of performance-based compensation at 90% and the remainder is fixed at 10%.

How We Review Market Compensation

In determining the total direct compensation for each NEO, the Compensation Committee generally considers a number of factors, including:

● the scope of the officer's responsibilities within the Company and in relation to comparable officers at various companies within the peer group described below;

● the experience of the officer within our industry and at the Company;

● performance of the Company and performance of the officer and the officer's contribution to the Company;

● the Company's financial budget and general level of total compensation increases throughout the Company for the coming year;

● historical compensation information for the individual officer;

● the recommendation of the CEO (other than with regard to his own compensation); and

● data regarding compensation paid to officers with comparable titles, positions or responsibilities at REITs that are considered by the Compensation Committee to be comparable for these purposes.

Although the Compensation Committee reviews the officers' compensation relative to the peer group, target compensation is not mechanically set at a particular percentage of the peer group average. An officer's target compensation may vary from the peer group data for the following reasons:

● the officer's role and experience within the Company may be different from the role and experience of comparable officers at the peer companies;

● the actual compensation for comparable officers at the peer companies may be the result of over-performance or under-performance by the peer group;

[**Table of Contents**](#TOC)

● the performance goals for comparable officers at peer companies may not have the same rigor as those established by the Compensation Committee; and

● the Company's performance may vary significantly from the performance of peers.

The Compensation Committee believes that the ultimate decision as to appropriate target compensation for a particular officer should be made based on the full review described above.

How We Select and Use Peer Groups

#### Peer Group for Market Compensation Purposes
The Compensation Committee uses a peer group when evaluating the appropriate levels of executive compensation. In determining the peer group composition, the Compensation Committee considers the following elements:

● Asset focus (multifamily/complexity of operations): a meaningful portfolio of multifamily properties and/or intense property management operations

● Size: defined as total capitalization (equity plus debt), generally within 0.5x to 2.0x of AvalonBay

● Talent: companies with which we could compete for talent

The peer group for 2025 compensation decisions consisted of the companies listed below.

**Total Capitalization (Equity + Debt)**

#### ($ in billions as of Dec. 31, 2025)

#### Peer Groups for Performance Award Measurement Purposes
The Compensation Committee uses a different peer group and select REIT indices for determining performance under the executives' performance awards. The REIT indices and peer group emphasize multifamily peers rather than similarly sized REITs from varying sectors since the performance metrics—operating performance and shareholder return—are more appropriately compared with direct competitors in our specific sector of the real estate industry.

For the portion of the 2025-2027 performance awards that may be earned based on three-year relative TSR, we used two indices. The FTSE Nareit Equity Apartments Index represents REITs in the U.S. multifamily housing industry. The FTSE Nareit Equity REITs Index represents a comprehensive group of REITs that spans the U.S. commercial real estate industry, and includes all investment and property sectors other than REITs that have been designated as Timber REITs or Infrastructure REITs.

For the portion of the 2025-2027 performance awards that may be earned based on operating metrics, the peer group consisted of the following multifamily REITs:

● Camden Property Trust

● Equity Residential

● Essex Property Trust, Inc.

● Mid-America Apartment Communities, Inc.

● UDR, Inc.

These companies were selected primarily for their status as publicly traded entities within the multifamily industry, with a size and geographic presence comparable to AvalonBay.

How We Establish Goals and Determine Achievement for Incentive Compensation

#### Setting Goals
At the beginning of each year, the Board reviews and concurs with the Company's business plan and budget, and management proposes to the Compensation Committee corporate goals for that year for the corporate component of the annual cash bonus program and the multi-year performance program. The Compensation Committee reviews the budget and the proposed goals, adopts any revisions to the proposed goals it deems appropriate, and approves the final corporate goals. The approved targets are intended to be rigorous, and our annual goals are consistent with our business outlook provided to the investment community and our business plan.

Annual business unit goals, which align with the Company's business plan, are drafted by the head of each business unit and reviewed, modified, and approved by the Chief Executive Officer and presented to the Compensation Committee.

The individual goals for the annual bonus program are determined in a similar manner. The goals for the Chief Executive Officer are determined and approved by the Compensation Committee. Goals for the other NEOs are determined by the Chief Executive Officer.

#### Determining Achievement
At the end of each year, the CEO reviews and reports to the Compensation Committee his assessment of the achievement of the corporate goals for both the annual bonus program and the long-term incentive program, as well as achievement of the business unit and individual goals and performance for the annual bonus program for the other NEOs. Actual bonus awards and compensation changes for the CEO, and all executive officers, are approved by the Compensation Committee.

Compensation Consultant

The Compensation Committee has engaged Ferguson Partners Consulting L.P. ("FPC"), an executive compensation consulting firm, to provide advice regarding executive compensation, including trends and changes in executive and Board compensation, regulations, and governance practices. FPC discusses the impact of these trends and changes on the Company, particularly in light of the Company's

compensation structure and levels, and provides general commentary regarding the Company's executive compensation structure, goals and levels.

In 2025, FPC also provided certain services to the Company's management related to benchmarking pay for selected officer-level associates. The decision to engage FPC for these additional services was made by management.

The Compensation Committee considered whether FPC's and its affiliate's work for the Company raised any conflict of interest, taking into account relevant factors in accordance with SEC guidelines. One of the factors considered was the prior engagement of FPC by management. The Committee determined that, in light of the nature of the advisory work that FPC does for the Company, the total fees paid to FPC and its affiliates for various services, and the policies that FPC and its affiliates have put in place to prevent compensation advisor conflicts of interest, the engagement of FPC and its affiliate does not create any material conflict of interest.

### 2025 Compensation Framework and Decisions
With respect to 2025 compensation matters for our NEOs, the Compensation Committee reviewed and approved the following: (i) base salaries, (ii) target cash and stock bonuses, (iii) criteria and metrics for the 2025 annual cash and annual stock bonuses to be paid in 2026, and (iv) 2025-2027 multi-year performance awards. These reviews and determinations are discussed below.

Base Salary

The Compensation Committee reviews the executive officers' base salaries annually by considering information from the relevant peer group, internal pay equity, and each executive's position, experience, demonstrated abilities, and level of achievement. In establishing the base salary for each NEO, the Compensation Committee reviewed a reference market rate after considering comparator group company data and evaluated whether that rate should be adjusted based on differences in the scope of the NEO's position as compared to the scope of comparable positions in the industry and the comparator group companies. The reference market rate is for review purposes only, and base salaries are not determined by the reference market rate. None of the NEOs received a base salary increase in 2025.

The table below sets forth the 2025 annual base salaries for the NEOs.

Annual Cash Incentive Program

Our annual cash bonus program emphasizes short-term goals. The performance measures we assessed to determine payouts under the 2025 Annual Cash Incentive Program are described below.

#### Annual Cash Incentive Mix
![Graphic](avb-20250520xdef14a_a174.jpg)

For each metric, the payout is as follows:

---

| | |
|:---|:---|
| **Performance level** | **Payout percentage** |
| Below threshold | No payout |
| Threshold | 50% |
| Target | 100% |
| Maximum or better | 200% |

---

Payouts for achievement of each metric are based on linear interpolation for results between threshold and target or target and maximum and payout is 0% for achievement below threshold.

Core FFO per Share

Core FFO per share is a key measure of the Company's performance and is, with some variation among REITs, an industry-wide measure. Similar to last year, the Company has an annual metric for this measure as well as a semi-annual metric that measures Core FFO per share versus budget in the first half ("1H") and versus reforecast in the second half ("2H") of the year. The annual and the semi-annual year goals are not duplicative of each other because of the difference in time periods. As the year progresses, the second half target goal may increase or decrease, depending on the Company's outlook for the remainder of the year.

Development Yield

Development continues to drive value creation at AvalonBay. The Development Yield metric is based on projected NOI divided by total capitalized cost for communities completed during the year that have largely completed lease-up, as compared to our original budgeted yield for such developments. The target goal is based on meeting our pre-established budgeted yield for each development community. Performance is determined based on the weighted average of the stabilized development yields compared to the weighted average of the original budgeted yields for the basket of annual completions. The yields are weighted based on total capitalized cost. The original budgeted development yield is established at construction start for each property based on each property's projected NOI divided by total capitalized cost. In this case, the actual variance in stabilized yield compared to original budgeted yield for the 2025 development communities resulted in above target payout with respect to that metric.

GRESB

GRESB is an organization that reviews CR data, scores and benchmarks on the real estate and infrastructure industries. The GRESB score is an overall measure of CR performance, including commitment, disclosure, and implementation. Our CR goals include reductions in Scope 1, 2 and 3 greenhouse gas emissions, reductions in waste and water, improvement in our score measuring associate engagement and satisfaction, and increases in our annual community philanthropic investments.

AvalonBay's 2025 GRESB score of 83.8 is based on an 80% weighting to the Standing Investment benchmark and a 20% weighting to Development (out of a possible 100). This score reflects the Company's continued progress on the emissions reduction targets and our public commitment to a low-carbon and renewable energy future. AvalonBay maintains its commitment to energy efficiency, increased renewable energy production, and leveraging third-party environmental certification to support the development of communities that align with its long-term environmental goals, among other factors.

Customer Satisfaction – Mid-Lease Net Promoter Score ("NPS") and Online Reputation Sentiment

Mid-Lease NPS

Mid-Lease NPS measures customer feedback from residents who have an active six-month or longer lease agreement and are at the midpoint of that lease term. The NPS is calculated by determining the percentage of Promoters (responding residents who provided a 9 or 10 rating) and subtracting the percentage of Detractors (responding residents who provided a rating of 6 or below). Residents are surveyed through an independent third-party platform.

For 2025, AvalonBay continued using semi-annual measures for the mid-lease NPS metric with each period weighing 50%. The target range was set at 29-33 for each period with a threshold goal of 25 corresponding to a 50% payout, and a maximum goal of 37 corresponding to a 200% payout. The final weighted NPS for 2025 was 33.5 (34 for the first half and 33 for the second half), resulting in a weighted 112.5% achievement.

Online Reputation Sentiment

Online reputation sentiment measures the average rating of new reviews within the calendar year for all AvalonBay communities (including communities in lease-up or undergoing redevelopment) and that are still live on Google as of the end of the calendar year. This information is monitored and scored by a third party.

Our online reputation sentiment was 4.4 out of 5.0 stars in 2025, which was above the target goal of 4.25. The positive online reputation sentiment continued to be driven by the outstanding service of AvalonBay's maintenance teams and the responsiveness of on-site leasing staff through their interactions with prospects and residents.

#### Qualitative Performance Metrics
The following metrics represent qualitative assessments of AvalonBay's performance.

Strategic & Corporate Technology Initiatives

Determining our progress on strategic and corporate initiatives requires a qualitative judgment about our achievement on multi-year corporate investments and projects. Our 2025 strategic and corporate initiatives included:

● Continuing to innovate and transform our operations through seamless, digital and self-service experience, enhanced neighborhood and centralized staffing models, and a modernized technology stack including AI solutions to deliver excellent customer service and reduce administrative and cost burdens at the same time.

● Making accretive investments in established and expansion regions, increasing development through in-house development and the Developer Funding Program (the "DFP"), and continuing to leverage our Structured Investment Program (the "SIP") to drive earnings.

● Continuing to progress towards our long-term target of increased portfolio allocation in expansion regions.

● Focusing on reducing environmental impact and operating expenses, through reducing emissions across all scopes, expanding solar programs, assessing and piloting lower embodied carbon construction products or approaches, and reducing water consumption and waste diversion.

The Compensation Committee considered the Company's performance against these and other initiatives and determined that achievement for 2025 was 100% of target. In making this determination, factors considered included the following:

● We continued to develop and enhance digital, self-service applications to support prospective and existing customer experiences when touring, searching for an apartment, applying, and leasing or renewing. Digital applications featured improvements that were implemented to enhance our website experience, flexible touring options and self-service leasing and renewal capabilities. We added smart access with keyless entry at more communities, deployed digital notice to vacate enhancements, and enhanced our digital touring features. We launched pilots of resident self-service options for adding pets and parking to leases, a new parking revenue app and a new resident app at more communities. We continue to optimize our neighborhood and centralized staffing

models by implementing management reporting, benchmarks and controls for the maintenance function. We also piloted a new leasing operations model across select neighborhoods.

● We exceeded development start volume for the year in both established and expansion regions. We started three new communities under the Developer Funding Program and continued to grow the Structured Investment Program. We also achieved 100% in-house construction management in expansion regions (other than for DFP developments) by the end of 2025.

● We met our transaction volume targets for the year as we continued to conduct asset-level strategy reviews, and evaluate the portfolio for optimization opportunities via dispositions and accretive capital investments.

● We continued our focus on reducing the environmental impact on the communities in which we do business. By the end of 2025, 94 solar projects were active with 69 installations. Lower embodied carbon construction materials were tested and implemented in four new developments. Progress on California de - turfing efforts is underway, with upcoming pilots designed to transition properties to native, low - water landscaping. We expanded water - saving initiatives through new fixture technologies and smart metering projects and completed leak - management pilots that will scale to additional regions next year.

Effectiveness of Management

This qualitative measure considers capital allocation and balance sheet and liquidity management and is weighted 10%. In 2025, we continued to build out the pipeline of development opportunities, carefully managing liquidity through match-funding and land exposure using option contracts. Our balance sheet ratios continue to remain strong with Net Debt-to-Core-EBITDAre at 4.7x (based on the annualized fourth quarter 2025) and 95% unencumbered NOI. The Company is well poised to capitalize on growth opportunities should they arise.

*\** *Based on the first and the second half year's results relative to Same Store Residential Revenue budgeted at the beginning of each period, respectively. Each half year achievement is weighted equally at 12.5%.*

*\*\** *Adjusted down to the lower figure per the discussion below.*

These performance measures intentionally do not duplicate the performance measures for the corporate annual cash bonus program to ensure that the CEO focuses on all aspects of the Company's business, including residential services, development and construction. Consistent with the semi-annual Core FFO metric used in the annual bonus plan, the Same Store Revenue metric was set and reviewed on a semi-annual basis instead of annually. The annual same store controllable operating expense metric is measured against budget as established at the beginning of the year and is designed to complement the Same Store Residential Revenue metric by incorporating the expense components of Net Operating Income. The base rental revenue metric compares our growth against a submarket composite based on stabilized communities. The Development metric focuses on completions against plan in terms of capital cost. The Construction metrics measure budget, safety and quality of completed communities.

For 2025, although Development completions occurred in advance of the goal and at lower-than-expected cost, the low volume of completions made this achievement have an outsized impact on the related performance measure. Because of this dynamic, and the favorable buyout environment in Construction, the Compensation Committee determined it was appropriate to apply negative discretion to align payouts for these components with the underlying performance of the Development and Construction Business Units. Specifically, Development performance was reduced to 117.4% of target and Construction performance was reduced to 132.5% of target. The revised performance resulted in a reduction of the total achievement from 129.8% to 110.7%.

Once the final achievement for the annual stock bonus is determined, the number of shares of restricted stock earned by each NEO is calculated and awarded in February of the year following the performance period. The restricted stock vests ratably over three years after the grant date as long as the NEO remains employed by the Company through each vesting date. Vesting will be accelerated in the event of a termination due to death, disability, retirement, or termination by the Company without cause. For Mr. Schall's 2025 stock bonus, in accordance with an election made prior to the end of the prior calendar year and as permitted under the Company's compensation program for officers, Mr. Schall received 25% of his earned stock bonus value in the form of a stock option that follows the same vesting schedule as restricted stock; the option has a total Black-Scholes value equal to 25% of the value of the earned stock bonus.

Annual stock bonus awards (and the option award in lieu of stock as described above) in respect of 2025 service will be disclosed in the 2027 proxy statement Summary Compensation Table as they were granted in February 2026.

New Hire Replacement Stock Awards

Ms. Thomas was hired in July 2024 and did not receive a maturing 2022-2024 performance award. Instead, she received a restricted stock award on March 1, 2025 as part of her new hire package, with a value of $275,000, which fully vested on March 1, 2026.

Multi-Year Performance Award Program

Under our multi-year, long-term incentive award program, performance awards are granted each year with a target number of performance units and the number of units earned may be reduced or increased from the target number at the end of the three-year performance period depending on achievement against established metrics. For the 2025–2027 performance period, payouts will be determined based on the Company's performance against two relative TSR metrics and two relative financial operating metrics, as described below. The performance units that are earned at the end of the performance period will be settled in shares of common stock and a cash payment equal to the dividends that would have been earned on that number of shares from the grant date of the award through its settlement date.

The performance awards strengthen the alignment of executive compensation with long-term stockholder value creation. The two indices selected for the relative TSR metric represent the broader REIT industry and the REIT apartment industry, which we believe are complementary investment vehicles for our investors. The operating metrics for the 2025–2027 Performance Awards—Core FFO per share growth and Net Debt to Recurring EBITDA ratio, each measured relative to the performance of our peers—motivate our officers to focus on critical operating performance objectives that we believe will contribute to sustainable stockholder returns over the long term. The three-year Core FFO per share growth has a higher weight because it is a key financial metric for the Company.

The targets set for the four performance metrics are intended to be challenging. Achievement of maximum performance levels would require meaningful outperformance over the performance period.

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *To derive the target number of TSR Metric units and the number of Operating Metric units, 100% of the target dollar value allocable to that metric was divided by the 20 trading day average closing stock price of the Company's common stock ending on December 31, 2024, of $224.2260. For the Summary Compensation Table, the value of the TSR Metric target units was determined using a Monte Carlo value of $224.11 for each unit, and the value of the Operating Metric units was determined based on the closing stock price on the grant date on February 26, 2025 of $221.58. The shares of stock issued upon settlement of awards are not subject to further additional time vesting requirements and will be delivered together with a cash payment representing the dividends that were paid on the number of earned shares from the date of grant of the award through the date of its settlement.*

Realized Pay for 2025 Performance

The following chart shows one of the ways our Compensation Committee evaluated compensation paid to the NEOs for service and performance with respect to 2025. This chart differs from the Summary Compensation Table. The Summary Compensation Table includes several items that are driven by accounting and reporting requirements that do not necessarily reflect the compensation actually realized by our NEOs during or with respect to 2025. The primary differences between the 2025 compensation of our NEOs as reported in this Realized Pay for 2025 Performance Table and as reported in the Summary Compensation Table are the following: (i) the Summary Compensation Table uses the grant date fair value of restricted stock awarded in February 2025 with respect to 2024 service, whereas the Realized Pay for 2025 Performance Table uses the grant date fair value of restricted stock awarded in February 2026 with respect to 2025 service, and (ii) the Summary Compensation Table uses the grant date fair value of the 2025–2027 performance awards that were awarded in February 2025, whereas the Realized Pay for 2025 Performance Table uses the value (as of the date of settlement) of the

unrestricted shares, and cash in respect of accrued dividends, received by each NEO upon settlement of the maturing 2023–2025 performance awards.

![Graphic](avb-20250520xdef14a_a204.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;*1.* *Cash bonus reflects the cash awards made in February 2026 with respect to performance under the annual cash bonus program in 2025 in the following amounts: Mr. Schall - $1,815,540, Mr. O'Shea - $999,650, Mr. Birenbaum - $1,157,088, Mr. Breslin - $1,087,320, and Ms. Thomas - $912,450.* 

&nbsp;&nbsp;&nbsp;&nbsp;*2.* *Represents 2025 earned annual stock bonuses in the following amounts: Mr. Schall - $2,296,494, Mr. O'Shea - $1,107,399, Mr. Birenbaum - $1,424,131, Mr. Breslin - $1,256,180, and Ms. Thomas - $696,324. Mr. Schall elected to receive 25% of his 2025 earned stock bonus in the form of a stock option, and accordingly 25% of the amount for Mr. Schall was issued in the form of a stock option in lieu of restricted shares of stock.* 

&nbsp;&nbsp;&nbsp;&nbsp;*3.* *For performance awards, target value reflects the dollar value used by the Company in February 2023 to determine the target number of 2023–2025 performance award units granted to the NEO. For performance awards, realized value reflects the February 2026 settlement value of the 2023–2025 performance awards (which consists of unrestricted shares and a dividend equivalent cash payment on those shares) in the following amounts: Mr. Schall - $6,801,580, Mr. O'Shea - $2,137,548, Mr. Birenbaum - $2,429,050, Mr. Breslin - $2,429,050, and Ms. Thomas - $991,025. The value of the unrestricted shares received by each NEO upon settlement of the 2023–2025 performance awards was calculated using a price of $179.67 per share, the closing price of the Company's common stock on the NYSE on February 26, 2026.*

### Other Benefits
Pursuant to our Deferred Compensation Plan, certain employees, including the NEOs, may defer up to 25% of annual base salary and up to 50% of annual cash bonus on a pre-tax basis and receive a tax-deferred return on those deferrals. Deferral elections are made by eligible employees during an open enrollment period each year for amounts to be earned in the following year. Participating employees direct the deemed investment of their deferral accounts by selecting among certain available investments in mutual funds.

We have an employee stock purchase plan that provides our employees the opportunity to purchase our common stock at a 15% discount to the lower of the closing price of the common stock, as reported on the NYSE, on the first business day of the purchase period or the closing price of the common stock on the last day of the purchase period. There were two purchase periods in 2025: January 1 through June 10 and July 1 through December 10. Employees had the opportunity to purchase up to $12,500 of our common stock at the discounted rate during each of the two purchase periods.

We maintain a 401(k) retirement savings plan and we match 50% of the contributions up to the first eight percent of a participant's eligible compensation (subject to certain tax limitations). We offer medical, dental and vision insurance plans, with a portion of the cost paid by the employee. We also provide 100% paid parental leave, mental and physical wellness programs, life insurance, accidental dismemberment insurance, and short-term and long-term disability insurance for each employee.

### Compensation Policies

#### Senior Officer Stock Ownership Guidelines
The Company believes it is important for senior officers to hold Company stock. To that end, the Board has established the Senior Officer Stock Ownership Guidelines for officers who are at the senior vice president level or above. These guidelines provide that the following classes of senior officers are expected to maintain ownership of common stock (including unvested restricted shares) equal to the indicated multiple of base salary. Stock that counts towards satisfaction of these guidelines includes shares owned by the officer or his or her immediate family sharing the same household, including shares of restricted stock still subject to vesting as well as shares purchased through the Company's employee stock purchase program. Shares underlying stock options or multi-year performance awards do not count toward satisfaction of these guidelines.

Covered officers must achieve the required ownership within five years of the date they become subject to these guidelines. The full text of the Senior Officer Stock Ownership Guidelines, which includes a retention policy for officers who have not achieved the required ownership level, is posted on the Investor Relations section of the Company's website (www.avalonbay.com) under "Corporate Governance Documents." All of our covered officers who have been in office for at least five years are in compliance with the stock ownership guidelines.

"No officer and no member of the Board of Directors of the Company may, directly or indirectly (including, without limitation, through accounts owned by immediate family members sharing the person's household and/or not financially independent of such person or through trading done through an account over which the person has investment power or authority), purchase Company equity securities on margin, hold Company equity securities in a margin account, or borrow money from a broker or other lender that is secured by Company equity securities."

Severance Policy

The Board has adopted a Policy Regarding Shareholder Approval of Future Severance Agreements (the "Severance Policy"). The Severance Policy generally provides that the Company will not, without stockholder approval or ratification, enter into or bind the Company to the terms of any severance agreement with a senior executive officer that provides for severance benefits (as defined therein) in excess of 3.0 times the sum of the officer's base salary plus annual bonus. The full text of the Severance Policy is posted on the Investor Relations section of the Company's website (www.avalonbay.com) under "Corporate Governance Documents."

Compensation Recovery Policy ("Clawback" Policy)

The Board has adopted a compensation recovery (or "clawback") policy (the "Compensation Recovery Policy"), which requires recovery from executive officers of incentive-based compensation that is earned, granted or vested based on the achievement of a financial reporting measure in the event of a required restatement of previously issued financial statements. The recoverable compensation includes any compensation received after the effective date of the Compensation Recovery Policy and in the three-year fiscal period preceding the date the Company was required to prepare the restatement that is in excess of the amount that would have been earned, paid or vested had it been calculated based on the restated financial statements. Recovery is required regardless of fault or a covered officer's role in the financial reporting process. Further, the Company has maintained the provisions of its prior compensation recoupment policy allowing the Board or the Compensation Committee discretion to require forfeiture or reimbursement of incentive compensation paid or awarded to any officer holding the title of senior vice president or above and not covered by mandatory clawback under the Compensation Recovery Policy. The Compensation Recovery Policy has been filed as Exhibit 97 to the Form 10-K, and is posted on the Investor Relations section of the Company's website (www.avalonbay.com) under "Corporate Governance Documents." At no time during or after the year ended December 31, 2025 was the Company required to prepare an accounting restatement that required recovery of erroneously awarded compensation pursuant to the Compensation Recovery Policy, nor was there, on December 31, 2025, an outstanding balance of erroneously awarded compensation to be recovered from the application of the policy to a prior restatement.

Dates and Pricing of Stock and Option Grants

The Compensation Committee approves the number of shares underlying options or the number of shares of restricted stock to award to officers as part of their annual compensation. The award date for options and stock grants is a date in February set by the Compensation Committee, but that date may be delayed if there is a pending announcement by the Company of material non-public information, such as an earnings release. In all cases, our stock and options are granted: (i) on the date described above; (ii) the first business day of the month following the date of (or a date set in connection with) a new employee's start with the Company, as approved by the Chief Executive Officer or the Compensation Committee in advance of the start date; or (iii) the first business day of the month following the date of approval by the Chief Executive Officer for retention or recognition purposes (under his delegated authority to grant equity awards to certain employees of up to a Board-authorized maximum value of $500,000). Option exercise prices are equal to the NYSE closing price of our common stock on the date of grant. Accordingly, we do not time the disclosure of material non-public information for the purpose of affecting the value of executive compensation.

Under Item 402(x)(2) of Regulation S-K, companies are required to provide a tabular disclosure on a grant-by-grant basis of each option awarded to the NEOs within the period beginning four business days before the filing of a periodic report on Form 10-Q or Form 10-K, or a Form 8-K that discloses material non-public information, and ending one business day after such filing. During fiscal 2025, the Compensation Committee awarded stock options to the CEO at its regularly scheduled February meeting, which occurred within four business days prior to the filing of our Annual Report on Form 10-K. We are therefore providing the following tabular disclosure.

| &nbsp;&nbsp;Mr. Schall | CEO | 2/26/2025 | 9473 | $221.58 | $482365 | 2.10% |

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *The amount reflects the grant date fair value of stock option awards made pursuant to the Company's Second Amended and Restated 2009 Equity Incentive Plan in the fiscal years ended December 31, 2025, computed in accordance with FASB ASC Topic 718, disregarding the effect of forfeitures related to service-based vesting.*  

Insider Trading Policies and Procedures

We have insider trading policies and procedures (the "Insider Trading Policy") that govern the purchase, sale and other dispositions of our securities by directors, officers, and employees, as well as by the Company itself. We believe these policies and procedures are reasonably designed to promote compliance with insider trading laws, rules and regulations and applicable listing standards. A copy of our Insider Trading Policy has been filed as Exhibit 19.1 to the Form 10-K, and is posted on the Investor Relations section of the Company's website (www.avalonbay.com) under "Corporate Governance Documents."

Pursuant to our Insider Trading Policy, all officers and directors must receive prior authorization for any purchase or sale of our common stock (unless made pursuant to a previously approved Rule 10b5-1 plan, by automatic dividend reinvestment, or through our employee stock purchase plan), which, in the case of open market transactions, is generally only given during approved trading windows that are established in advance based upon earnings release dates.

### Risk Considerations
The Compensation Committee reviewed and considered risks arising from the Company's compensation policies and practices for its employees. This review included consideration of the following specific elements of the Company's executive compensation policies and procedures:

● preexisting, defined goals are set for annual bonuses and long-term incentive awards;

● annual goals contain multiple financial targets, including performance against a pre-approved budget;

● performance goals include both absolute performance and performance relative to industry peers;

● annual goals balance financial and non-financial performance;

● incentive plans incorporate goals for corporate, business unit, and individual performance;

● performance goals include achievement against both single year and multi-year metrics;

● executive compensation is structured as a mix of salary, cash bonus, and equity awards;

● equity awards vest over time with a minimum vesting period of one year;

● the provisions of the Compensation Recovery Policy;

● bonus and long-term equity programs include maximum payout levels;

● all unvested equity awards are forfeited upon a termination of employment for cause or voluntary termination under certain circumstances;

● the metrics that determine our incentive awards include a goal addressing appropriate leverage ratios; and

● while awards are generally made in relation to performance against specific goals, the Compensation Committee retains the discretion to adjust annual bonuses of cash and restricted stock as may be warranted by specific circumstances.

Following this review, the Compensation Committee concluded that any risks arising from the Company's compensation policies and practices are not reasonably likely to have a material adverse effect on the Company at this time.

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *The amounts shown as salary in column (c) reflect actual payments received in each indicated year, which may vary slightly from the salary described in the Compensation Discussion and Analysis as a result of (i) the number of payroll periods in each calendar year and (ii) the fact that salary increases do not go into effect until early March of each year (except for 2024, in which year the salary increases went into effect in February).* 

&nbsp;&nbsp;&nbsp;&nbsp;*(2)* *The amounts in column (e) include restricted stock awards actually granted during the fiscal year for service in the prior fiscal year. For example, the row for 2025 includes the value of stock awards made in February 2025 with respect to 2024 service. The amounts in column (e) also include the grant date fair value of the performance award granted for that year. For example, the row for 2025 includes the 2025–2027 performance award that was granted in February 2025.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(3)* *The amounts in column (e) reflect the aggregate grant date fair value for awards made in the fiscal years ended December 31, 2025, December 31, 2024, and December 31, 2023, as applicable, computed in accordance with FASB ASC Topic 718, disregarding the effect of forfeitures related to service-based vesting, for restricted stock awards and performance unit awards made pursuant to the Company's Second Amended and Restated 2009 Equity Incentive Plan. The value of restricted stock awards is based solely on the closing price of our common stock on the NYSE on the date of grant and no assumptions were used in the calculation of this value. The value of performance unit awards based on operating metrics made in 2025, for the measurement period January 1, 2025 – December 31, 2027, is based on the closing price of our common stock on the NYSE on February 26, 2025, the date of grant, of $221.58. The value of performance unit awards based on TSR metrics made in 2025 for the measurement period 2025–2027 is based on the Monte Carlo value on February 26, 2025 of $224.11. The total realizable value of the performance unit awards granted in 2025, if earned at maximum on the date of grant, for the NEOs is: Mr. Schall—$9,745,192; Mr. O'Shea—$3,088,600; Messrs. Birenbaum and Breslin—$3,498,424; and Ms. Thomas—$1,780,650.*

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *The amounts shown in columns (d), (e) and (f) reflect the threshold, target, and maximum payment levels for 2025 under our annual bonus plan, which were established on February 26, 2025. The annual bonus is paid in cash and restricted stock. The actual cash bonuses received by each of the NEOs for performance in 2025, paid in 2026, are set out in column (g) of the Summary Compensation Table. Under applicable SEC rules, earned stock bonuses will be disclosed in the 2027 proxy statement Summary Compensation Table as the actual grant of restricted stock based on 2025 achievement occurred in 2026.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(2)* *The amounts shown in columns (g), (h) and (i) reflect the threshold, target and maximum number of performance units awarded in 2025 under the long - term incentive performance program. The grant date fair value of 2025–2027 awards is based on the closing price on February 26, 2025, the grant date, of $221.58 for the operating metric portion of the award and the Monte Carlo value of $224.11 for the TSR metric portion of the award. Cash dividends will be accrued and paid at the end of the performance period based on the actual number of performance units earned.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(3)* *The shares of restricted stock shown in column (j) granted on February 26, 2025, represent the actual number of shares of restricted stock granted to the NEOs, with respect to performance in 2024, and do not represent compensation for performance in 2025. The shares of restricted stock shown in column (j) granted on March 1, 2025, reflect a one-time award to Ms. Thomas pursuant to the terms of her offer letter. Dividends are payable on the shares at the same rate as dividends paid on all outstanding shares of our common stock.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(4)* *The stock option has an exercise price equal to the closing stock price on the date of grant at $221.58 per share, vests ratably over a three-year period ending March 1, 2028, and has a 10-year term.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(5)* *For the February 26, 2025 grants of restricted stock, the value was calculated based on the closing price of the common stock on the date of grant of $221.58. For the March 1, 2025 grant of restricted stock, the value was calculated based on the closing price of the common stock on the date of grant of $226.18. For the February 26, 2025 stock option grant, the grant date fair value of the option award was determined as of the option grant date using a Black-Scholes stock option valuation model. The assumptions used to determine the grant date fair value are described in footnote (4) to the Summary Compensation Table.*

### Nonqualified Deferred Compensation
Pursuant to our Deferred Compensation Plan, certain employees of the Company, including the NEOs, may defer up to 25% of annual base salary and up to 50% of annual cash bonus on a pre-tax basis and receive a tax-deferred return on those deferrals. Deferral elections are made by eligible employees during an open enrollment period each year for amounts to be earned in the following year. Participating employees direct the deemed investment of their deferral accounts by selecting among certain available investment funds. The table below shows the investment funds available under the Deferred Compensation Plan and their annual rate of return for the calendar year ended December 31, 2025. Since the investment funds are all publicly available, we do not consider any of the earnings credited under the Deferred Compensation Plan to be "above market".

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *All contributions in column (b) are also included as compensation to the NEOs in the Salary and/or Non-Equity Incentive Plan Compensation columns of the Summary Compensation Table.* 

### Potential Payments Upon Termination or Sale Event
The summaries below are qualified in their entirety by reference to the complete plans and agreements which have been included as exhibits to the Company's SEC filings.

The Company is not party to employment agreements with any of the NEOs. Mr. Schall entered into an employment agreement to cover his first three years of employment, but that agreement expired as described below.

Mr. Schall's Former Employment Agreement

Mr. Schall joined AvalonBay in January 2021 as President, with an announced plan for him to transition to the role of Chief Executive Officer approximately one year later (which occurred on January 3, 2022). In connection with his hiring, the Company and Mr. Schall entered into an employment agreement with a term that expired by its terms in January 2024, although provisions relating to equity awards granted during the term of the employment agreement continue to apply with respect to those awards (principally to expand the definition of a termination without cause to include a departure by Mr. Schall for "Good Reason" as defined in the agreement).

Officer Severance Plan for Sale Events

We adopted an Officer Severance Plan that provides for severance in the event of certain terminations of employment following a Sale Event (as defined therein). Under this program, in the event an officer's employment is terminated by the Company (other than for cause or as a result of death or disability) in connection with or within 24 months of a Sale Event, such officer will generally receive a multiple of his Covered Compensation (defined as the sum of his or her annual base salary plus the officer's current target annual cash bonus as of the termination date) depending on the officer's title: for the Chief Executive Officer and President, the multiple is three times; for the Chief Financial Officer or an Executive Vice President, the multiple is two times; and for other officers the multiple is one times. The terminated officer would also receive (i) a cash payment representing the pro rata value of his or her annual bonus (cash and stock) for the portion of the year worked, valued at target, (ii) accelerated vesting of the officer's unvested restricted stock and options, and (iii) payment of COBRA insurance premiums for up to 18 months.

Other Severance Arrangements

Our agreements with our directors and officers governing compensatory stock option and restricted stock awards provide for vesting if a "Sale Event" with respect to the Company occurs and the participant's employment or other business relationship with the Company terminates for Good Reason or without Cause in connection with or within 24 months following the Sale Event (as each such term is defined therein).

In addition, upon death, Disability, termination by the Company without Cause, or the Retirement of an employee (as defined in the award agreements under the Equity Incentive Plan), (a) all of such employee's options shall automatically become fully exercisable and shall be exercisable for one year thereafter and (b) all of such employee's restricted shares of stock shall automatically vest 30 days following the triggering event; provided, at the Company's option, that a separation agreement is executed and effective during such 30-day period. Retirement of an employee, as defined in the award agreements under the Equity Incentive Plan, generally means the termination of employment, other than for Cause, when the sum of the following equals or exceeds 70 years: (i) the number of full months (converted to years) of employment and other business relationships with the Company and any predecessor company (must be at least 120 months) and (ii) the employee's age on the date of termination (must be at least 50 years old). Under this formula, Messrs. O'Shea, Birenbaum and Breslin are currently eligible for retirement. To qualify for retirement, the employee must also give six months' prior written notice to the Company of the employee's intention to retire and enter into a release and a two year non-solicitation and one year non-competition agreement.

Our current performance award agreements provide that, following one full year of employment during the performance period, a pro rata portion of the award will be earned at the end of the performance period based on actual achievement if there is a separation of employment due to death, Disability, Retirement, or a termination by the Company without Cause. If a Sale Event occurs during a performance period, then all outstanding performance awards vest at their target number of units and stock is issued for such number of units. The executive will also receive a cash payment for the dividends that would have been payable on the underlying shares in proportion to the actual number shares earned.

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *Upon termination of any employee's employment due to a qualified retirement as described above, in addition to the accelerated vesting of restricted stock (full) and performance awards (pro rata), the employee will receive their prorated annual bonus (cash and stock) paid in cash, six months of Company-paid COBRA premiums, and choice of retirement gift from an online catalog. Retirement benefits are available on the same terms to all associates. Neither Mr. Schall nor Ms. Thomas met the eligibility requirements for retirement on December 31, 2025. As such, estimated payments are not reported for either in the table above.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(2)* *The Compensation Committee of the Board of Directors from time to time reviews and establishes severance guidelines in the case of a termination by the Company without cause of an executive officer. The guidelines do not constitute a contractual right of an executive and are subject to change without notice as business needs and practices evolve. The Company may require that certain conditions be met before providing severance to an executive, such as requiring the executive to execute a general release, to continue employment with the Company for a period of time, to provide on-going cooperation on various matters, etc. The severance amount suggested in the guideline may be decreased, or eliminated, on a case-by-case basis depending on the nature of the executive's termination (e.g., reorganization, poor performance, etc.).* 

*In the absence of a decrease in the current guideline amount, the guidelines suggest a cash severance payment of two times base plus target cash bonus in the case of Mr. Schall ($5,500,000 as of December 31, 2025) and one and one-half times base plus target cash bonus in the case of the non-PEO named executive officers ($2,355,000, $2,550,000, $2,550,000 and $2,062,500 for Messrs. O'Shea, Birenbaum, Breslin, and Ms. Thomas respectively, as of December 31, 2025).*

*Outstanding equity awards would vest in accordance with their terms as is the case with other equity award participants who are terminated without cause. The executive officers would also receive six months of Company-paid COBRA medical insurance premiums, unless covered under another employer, and Company-paid outplacement services for up to 6-months of up to $5,000.*

&nbsp;&nbsp;&nbsp;&nbsp;*(3)* *In accordance with the terms of the Company's Officer Severance Plan, the amount represents three times Covered Compensation (base salary and the current year target annual cash bonus) for Mr. Schall.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(4)* *For 2023–2025 awards, value based on actual achievement, which includes a cash payment equal to the accrued dividends that would have been payable on such number of shares earned. For 2024–2026 and 2025–2027 awards, value assumes prorated vesting based on portion of the performance period completed and achievement assumed at target, as well as a cash payment equal to the accrued dividends that would have been payable on such number of shares earned.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(5)* *Value based on full vesting of unvested performance awards at target, as well as a cash payment equal to the accrued dividends that would have been payable on such number of target shares.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(6)* *Mr. Schall's stock options granted on February 17, 2023, February 23, 2024, and February 13, 2025 vest ratably over a three year period with the first portion of each grant vested on March 1, 2024, March 1, 2025, and March 1, 2026, respectively. The options automatically vest on the date of termination in the event of a termination by the Company without cause, due to death or disability, or a termination for good reason in connection with a sale event. If Mr. Schall's employment or other business relationship terminates for any other reason before the vesting dates, the options are forfeited. If the stock option exercise price is greater than the current stock price, the awarded stock options will have a zero intrinsic value.*

*In the case of the option granted to Mr. Schall on February 23, 2023: based on the December 31, 2025, stock price of $181.31 and the stock option exercise price of $177.83, this stock option has an intrinsic value of $3.48 per share in the event of a termination. For the option granted to Mr. Schall on February 13, 2024: based on the December 31, 2025, stock price of $181.31 and the stock option exercise price of $172.11, this stock option has an intrinsic value of $9.20 per share in the event of termination. For the option granted to Mr. Schall on February 26, 2025: based on the December 31, 2025, stock price of $181.31 and the stock option exercise price of $221.58, this stock option has zero intrinsic value in the event of termination.*

*Messrs. O'Shea, Birenbaum, Breslin, and Ms. Thomas held no unvested stock options as of December 31, 2025.*

&nbsp;&nbsp;&nbsp;&nbsp;*(7)* *COBRA medical insurance premiums will be paid by the Company for up to six months in the event of a death, qualified disability or qualified retirement.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(8)* *Reflects company-paid medical insurance premiums for up to 18 months, based on the executive's healthcare elections as of December 31, 2025.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(9)* *Zero cash and stock payment if terminated prior to April 1, 2025. Pro-rated target cash and stock bonus payment if terminated on or after April 1, 2025, but prior to December 31, 2025. If departure is close to the year end, actual cash and stock bonus may be provided. Actual cash and stock bonus payments based on 2025 performance are included in this table.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(10)* *In accordance with the Company's Officer Severance Plan, represents the target annual cash bonus and the target stock bonus assuming termination at year end.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(11)* *In accordance with the terms of the Company's Officer Severance Plan, represents two times Covered Compensation (base salary and the current year target annual cash bonus) for Messrs. O'Shea, Birenbaum, Breslin, and Ms. Thomas.* 

### CEO Pay Ratio
Under rules adopted pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, we are required to calculate and disclose the total compensation paid to our median paid employee, as well as the ratio of the total compensation paid to the median employee as compared to the total compensation paid to our Chief Executive Officer.

The following describes our methodology and the resulting Chief Executive Officer pay ratio, and is a reasonable estimate, based on all individuals employed by AvalonBay Communities, Inc. as of December 31, 2025. To identify the median employee, we utilized wages reported in Box 1 of IRS Form W-2. Box 1 pay was selected as the most appropriate, consistently applied compensation measure as it captures compensation earned through various incentive plans offered throughout the Company. Wages were annualized for employees who joined the Company during 2025. Employees who were hired in late December 2025, and consequently did not receive any wages in 2025, were excluded from the median employee calculation, consistent with SEC rules permitting the exclusion of employes who received no compensation during the year.

After identifying the median employee based on W-2 wages, total compensation for the median employee was calculated using the same methodology as was used for calculating the Chief Executive Officer's total compensation in the Summary Compensation Table. The annual total compensation for 2025 for the Chief Executive Officer was $9,663,500. The annual total compensation for 2025 for the median employee was $70,971, made up of approximately $69,669 in cash compensation and $1,302 in all other compensation, such as 401(k) Company contributions. As a result, the estimated ratio of the Chief Executive Officer's pay to the pay of the median employee is 136 to 1.

In an effort to provide additional context on the pay ratio disclosure, the Company is providing the following background information. As of December 31, 2025, we had 3,021 employees, of which 1,856 were employed on-site at our operating apartment communities and 41 employees were employed on a part-time basis. The total population also includes 238 employees at the Customer Care Center, our in-house administrative support and call center with physical locations in Virginia Beach, VA, and San Antonio, TX. The average tenure of all employees is approximately seven years. The Company generally staffs its business with full-time employees and not part-time employees or the employees of subcontractors; we do however use subcontractors on occasion to supplement the staffing at certain operating communities and we do on occasion use part-time or seasonal employees. With regard to our development and construction activities, we engage various other firms to engage in the professional design and construction of our communities (i.e., architectural plans, engineering plans, foundation work, carpentry, drywall, framing, etc.).

### Pay Versus Performance
As required by Item 402(v) of Regulation S-K, we are providing information for our Chief Executive Officer (who is our principal executive officer or "PEO") and the other NEOs about the relationship between "compensation actually paid" to such individuals (as calculated in accordance with Item 402(v) of Regulation S-K) and certain financial performance measures. For additional information on our compensation programs and philosophy and how we design our compensation programs to align pay with performance, see the section titled "Compensation Discussion and Analysis".

For AvalonBay, the "compensation actually paid" to our NEOs for a given year, as calculated in accordance with Item 402(v) of Regulation S-K, includes cash amounts paid for service, the value of other items included in "all other compensation" in the Summary Compensation Table, the change in the fair value of unvested equity awards during the year (through year end or at any earlier vesting date) and the year-end fair value of equity awards granted during the year that remain unvested at year end. In this way, "compensation actually paid" takes into account changes in the fair value of equity awards using closing stock prices and Monte Carlo values. Our equity awards consisted of restricted shares of common stock, stock options, and multi-year performance awards that are earned based upon the achievement of TSR and operating metrics. Accordingly, the "compensation actually paid" to our NEOs as reported in the table below was greatly influenced by the value of our common stock price, which varied over the measurement period as illustrated in the following table:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;**Fiscal Year End** | **Closing Stock Price** | **Year over Year Change** |
| &nbsp;&nbsp;December 31, 2025 | $181.31 | (18)% |
| &nbsp;&nbsp;December 29, 2024 | $219.97 | 17% |
| &nbsp;&nbsp;December 30, 2023 | $187.22 | 16% |
| &nbsp;&nbsp;December 31, 2022 | $161.52 | (36)% |
| &nbsp;&nbsp;December 31, 2021 | $252.59 | 57% |
| &nbsp;&nbsp;December 31, 2020 | $160.43 | (23)% |

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *Mr. Schall joined AvalonBay as President and a director in January 2021 and became Chief Executive Officer effective January 3, 2022. Mr. Schall's compensation for 2021 is included in the non-PEO averages.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(2)* *The amounts reported represent the "compensation actually paid" to each of Mr. Schall and Mr. Naughton and the average "compensation actually paid" to each of the other NEOs as a group, each computed in accordance with Item 402(v) of Regulation S-K, but do not reflect the actual amount of compensation earned by or paid to such NEOs. In accordance with Item 402(v) of Regulation S-K, the following adjustments were made to the amounts reported in the "Total" column of the Summary Compensation Table to calculate "compensation actually paid."*

&nbsp;&nbsp;&nbsp;&nbsp;*(6)* *The dollar amounts reported represent the amount of net income reflected in the Company's audited financial statements for the applicable fiscal year.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(7)* *The Company Selected Measure is Core FFO per share, representing the Company's FFO as adjusted for non-core items. By adjusting for items that are not considered by us to be part of our core business operations, Core FFO can help one compare the core operating and financial performance of the Company between periods. While we consider numerous financial and non-financial performance measures for the purpose of evaluating and determining executive compensation, we consider Core FFO per share, which is one of the measures used to determine annual cash incentive compensation for our NEOs, to be the most important performance measure used to link compensation actually paid to the NEOs for fiscal year 2025 to Company performance .* 

&nbsp;&nbsp;&nbsp;&nbsp;*(8)* *Non-PEO NEOs for 2025 and 2024 include Messrs. O'Shea, Birenbaum, Breslin, and Ms. Thomas.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(9)* *Non-PEO NEOs for 2023 and 2022 include Messrs. O'Shea, Birenbaum, Breslin, and Schulman.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(10)* *Non-PEO NEOs for 2021 include Messrs. O'Shea, Schall, Birenbaum, and Breslin.*

Compensation Actually Paid and Company TSR

Changes in our stock price during the five-year period measured had a direct influence on the value of outstanding equity awards held by our NEOs, which impacted year to year "compensation actually paid." In addition, changes in our stock price relative to peers influenced our interim measured level of performance on outstanding performance awards and affected the year end values of such awards, which also impacted the "compensation actually paid" to our NEOs. This relationship between "compensation actually paid" for 2021 through 2025, and AvalonBay's TSR and a comparison of AvalonBay's TSR to the TSR of the peer group are illustrated in the chart below.

Compensation Actually Paid and Net Income

Our net income is affected by gains (or losses) on sales of improved property, and therefore can be variable and is not a metric used by our Compensation Committee for executive goal setting or measuring performance. Accordingly, there was little correlation between our net income from 2021 through 2025 and the "compensation actually paid" to our NEOs during those years, which is illustrated in the graph below.

Compensation Actually Paid and Core FFO per Share

Core FFO per share on an annual, absolute basis is an important financial performance measure for the Company and is used as one component of our annual corporate goals for determining annual cash bonuses. Growth in Core FFO per share over time may positively influence the Company's stock price, although many other factors affect the Company's stock price, such as trends in interest rates, job growth, the performance of stock indices and other factors. "Compensation actually paid" to our NEOs for 2021 through 2025 was influenced by significant movements in our stock price over that period that did not correlate closely to changes in our Core FFO per share, which is illustrated in the graph below:

## Proposal 4. Ratification of Selection of Independent Auditors
The Board recommends that the stockholders ratify the Audit Committee's selection of Ernst & Young LLP ("EY") as AvalonBay's independent auditors for fiscal year 2026. If the selection of EY is not ratified, the Audit Committee anticipates that it will nevertheless engage EY as auditors for fiscal year 2026 but will consider whether it should select a different auditor for fiscal year 2027. If the selection of EY is ratified by the stockholders, the Audit Committee may nevertheless determine, based on changes in fees, personnel or for other reasons, to engage a firm other than EY for the 2026 audit.

Representatives of EY are expected to be present via audio at the Annual Meeting and will have the opportunity to make a statement if they wish and to respond to appropriate questions.

Required Vote and Recommendation

Only holders of record of AvalonBay's common stock as of the close of business on the Record Date are entitled to vote on this proposal. Proxies will be voted for ratification of the selection of EY as AvalonBay's independent auditors for fiscal year 2026 unless contrary instructions are set forth on the enclosed proxy card. A majority of the total votes cast on the proposal at the Annual Meeting is required to ratify the selection of EY. Under Maryland law, abstentions and broker non-votes are not treated as votes cast. Accordingly, an abstention or broker non-vote will have no effect on the result of the vote.

### Report of the Audit Committee
The Audit Committee of the Board of Directors of AvalonBay Communities, Inc., a Maryland corporation (the "Company"), reviews the financial reporting process of the Company on behalf of the Board of Directors. Management has primary responsibility for this process, which includes the preparation of the Company's consolidated financial statements in accordance with generally accepted accounting principles and the design, implementation and evaluation of the Company's internal controls over financial reporting. The Company's independent auditors, and not the Audit Committee, are responsible for auditing and expressing an opinion on the conformity of the Company's audited financial statements to generally accepted accounting principles and evaluating the effectiveness of internal controls over financial reporting. In this context, during 2025 and 2026, the Audit Committee reviewed and discussed the audited financial statements and Ernst & Young LLP's evaluation of the Company's internal controls over financial reporting with management and the independent auditors. The Audit Committee has discussed with the independent auditors the matters required to be discussed by the Auditing Standards adopted by the Public Company Accounting Oversight Board ("PCAOB").

In addition, the Audit Committee received from the independent auditors the written disclosures required by the PCAOB regarding the independent auditor's independence, and the Audit Committee discussed with the independent auditors their independence from the Company and its management. Relying on the reviews, disclosures and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025, for filing with the SEC, and the Board of Directors has approved this recommendation. The Audit Committee and the Board have also recommended, for stockholder ratification, the selection of Ernst & Young LLP as the Company's independent registered public accounting firm for the year ending December 31, 2026.

## Some Questions You May Have Regarding This Proxy Statement
Q. What is included in these proxy materials and why did I receive them?

A. The proxy materials for our 2026 Annual Meeting of Stockholders include the Notice of Annual Meeting and this Proxy Statement. If you received a paper copy of these materials, the package also includes a proxy card or voting instruction form. Our Annual Report to Stockholders for the year ended December 31, 2025, and our Form 10-K for the year ended December 31, 2025, are being made available concurrently with the proxy materials but are not a part of the proxy solicitation materials.

Your proxy is being solicited on behalf of AvalonBay's Board of Directors. As a stockholder, you are invited to attend the Annual Meeting audio webcast and you are entitled and requested to vote on the proposals described in this Proxy Statement.

Q. Why did I receive a notice in the mail regarding the Internet availability of the proxy materials instead of a paper copy of the full set of proxy materials?

A. This year, we are again relying on an SEC rule that allows companies to furnish their proxy materials over the Internet. As a result, we are mailing to many of our stockholders a Notice of Internet Availability of the proxy materials (a "Notice") instead of a paper copy of the proxy materials. All stockholders who receive a Notice will have the ability to access the proxy materials electronically. The Notice explains how to request a paper copy of the proxy materials if you prefer that format.

Q. How can I access the proxy materials electronically?

A. This Proxy Statement, our Annual Report and our Annual Report on Form 10-K for the year ended December 31, 2025, are available online at www.proxyvote.com. Instead of receiving a Notice or copies of our future annual reports, proxy statements, and proxy cards by mail, stockholders can elect to receive an email that will provide electronic links to those documents and the proxy voting site.

Q. Who may vote at the Annual Meeting?

A. The Record Date for determining stockholders entitled to receive notice of, and to vote at, the Annual Meeting is March 23, 2026. You may vote all the shares of AvalonBay common stock that you owned at the close of business on the Record Date. On the Record Date, there were 139,111,236 shares of AvalonBay common stock outstanding and entitled to vote at the Annual Meeting. You may cast one vote for each share of our common stock held by you on all matters.

Q. How do I listen to and attend the audio webcast of the Annual Meeting?

A. This year's Annual Meeting will again be held entirely via a live audio webcast.

You can attend the Annual Meeting and submit your questions before and during the Annual Meeting by visiting www.virtualshareholdermeeting.com/AVB2026 and entering the 16-digit control number included in your proxy card or the voting instruction form or notice you received from your bank or broker or any other stockholder of record.

Q. What if I have technical difficulties or trouble accessing the virtual meeting?

A. Technicians will be available to assist you with any technical difficulties you may have accessing the virtual audio webcast of the Annual Meeting or during the Annual Meeting. For assistance, please call the technical support telephone number that will be posted at www.virtualshareholdermeeting.com/AVB2026

Q. What constitutes a quorum at the Annual Meeting?

A. The presence, in person or by proxy, of holders of a majority of the shares of AvalonBay common stock entitled to vote will constitute a quorum for the transaction of business at the Annual Meeting. Abstentions and "broker non-votes" will be counted for purposes of determining whether a quorum is present.

Q. What is a broker non-vote?

A. If you hold shares through a bank, broker or other institution, you are the "beneficial owner" of those shares, and you are entitled to tell the entity that is the record owner of your shares how to vote. With a few exceptions (like the ratification of the independent auditors), NYSE rules prohibit a bank, broker or other institution from voting the shares they hold without instructions from the beneficial owner. If you do not provide your voting instructions with respect to the election of directors or approval of our executive compensation, the entity that holds your shares will not be permitted to vote at the Annual Meeting on those matters. A "broker non-vote" refers to a share represented at the Annual Meeting held by a broker that has not received voting instructions from the beneficial owner or person entitled to vote such share on a matter for which the broker does not have discretionary voting power. Shares held for which there is a "broker non-vote" on a matter are considered represented at the meeting for purposes of establishing a quorum, if the broker has received direction, or has discretion, to vote on at least one matter.

Q. What proposals will be voted on at the Annual Meeting and what does the Board recommend?

A. The following proposals will be presented to stockholders at the Annual Meeting:

Q. How do I vote?

A. Whether you hold shares directly as the stockholder of record or indirectly as the beneficial owner of shares held for you by a broker or other nominee (i.e., in "street name"), you may direct your vote without attending the Annual Meeting. Holders of record may vote by granting a proxy, and beneficial owners may vote by submitting voting instructions to a broker or nominee. In most instances, you will be able to do this over the Internet, by telephone or, if you request printed copies of the proxy materials, by mail. Please refer to the instructions below and those included on your proxy card or, for shares you hold in street name, the voting instruction card provided by your broker or *nominee.*

***By Internet -*** If you have Internet access, you may authorize your proxy by following the "By Internet" instructions on the proxy card or, if applicable, the Internet voting instructions that may appear on the voting instruction card sent to you by your broker or nominee.

[**Table of Contents**](#TOC)

***By Telephone -*** If you are calling from the United States or Canada, you may authorize your proxy by following the "By Telephone" instructions on the proxy card or, if applicable, the telephone voting instructions that may appear on the voting instruction card sent to you by your broker or nominee.

***By Mail -*** If you request printed copies of the proxy materials, you may authorize your proxy by signing your proxy card and mailing it in the enclosed, postage-prepaid and addressed envelope. For shares you hold in street name, you may sign the voting instruction card included by your broker or nominee and mail it in the envelope provided.

Q. What if I change my mind after giving my proxy or voting instructions?

A. If you are a record holder of AvalonBay common stock, you may change your proxy instructions at any time before the vote at the Annual Meeting in one of three ways:

&nbsp;&nbsp;&nbsp;&nbsp;● by granting a new properly executed and later-dated proxy using the same method you originally used to authorize your proxy

&nbsp;&nbsp;&nbsp;&nbsp;● by filing a written revocation with the Secretary of AvalonBay at our address set forth below

&nbsp;&nbsp;&nbsp;&nbsp;● by attending the Annual Meeting via the live webcast and voting in person

Attendance at the Annual Meeting without further action will not revoke your previously granted proxy.

If you are a beneficial owner of AvalonBay common stock, you may change your proxy instructions by submitting new voting instructions to your broker or nominee in the manner and within the time periods that entity prescribes.

Q. What if I return a proxy card but don't fill it out completely?

A. If a properly signed proxy is submitted but not marked as to a particular item, the proxy will be voted with respect to that item as follows (i) FOR the election of the nominees for director named in this Proxy Statement, (ii) FOR the non-binding, advisory resolution to approve the compensation of our named executive officers, (iii) FOR the approval of our 2026 Equity Incentive Plan, and (iv) FOR the ratification of the selection of Ernst & Young LLP as our independent auditors for 2026. We do not anticipate that any matters other than those set forth in the Proxy Statement will be presented at the Annual Meeting. If other matters are presented, proxies will be voted in the discretion of the proxy holders.

Q. I live with other stockholders. Will we each get our own copy of the proxy materials?

A. If you and other residents at your mailing address own shares of AvalonBay common stock in street name through the same institution, your broker, bank or other nominee may have sent you a notice that your household will receive only one Annual Report, Notice of Annual Meeting and Proxy Statement. This procedure, known as "householding," is intended to reduce the volume of duplicate information stockholders receive and also reduce our printing and postage costs. If you consented or were deemed to have consented to householding, your broker, bank or other nominee may send one copy of our proxy materials to your address for all residents that own shares of our common stock in street name. If you wish to revoke your consent to householding, you must contact your broker, bank or other nominee. If you are receiving multiple copies of our Annual Report, Notice of Annual Meeting and Proxy Statement, you may be able to request householding by contacting your broker, bank or other nominee.

If you wish to request extra copies free of charge of our Annual Report or Proxy Statement, please send your request to the Corporate Secretary at the address below, call us with your request at 703-329-6300, or visit the "Investor Relations" section of our website at www.avalonbay.com. Upon written or oral request, we will promptly deliver a separate copy of the Annual Report or Proxy Statement. The content of our website is not incorporated by reference into this proxy statement or in any other report or document we file with the SEC, and any references to our website are intended to be inactive textual references only.

AvalonBay's 2025 Annual Report to Stockholders and a copy of the Annual Report on Form 10-K for the year ended December 31, 2025, as filed with the SEC, are being made available to stockholders concurrently with this Proxy Statement. The Annual Report to Stockholders and Form 10-K, however, are not part of the proxy solicitation materials. **A copy of any or all exhibits to our Annual Report on Form 10-K, and a copy of the Code of Business Conduct and Ethics, may be obtained free of charge by writing to our principal executive offices at the following address: AvalonBay Communities, Inc., 4040 Wilson Boulevard, Suite 1000, Arlington, VA 22203, Attention: Corporate Secretary (Legal Department) or by accessing the "Investor Relations" section of our website (www.avalonbay.com).**

### Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms
*This proxy statement contains certain non-GAAP financial measures and other terms. The definitions and calculations of these non-GAAP financial measures and other terms may differ from the definitions and methodologies used by other REITs and, accordingly, may not be comparable. The non-GAAP financial measures referred to below should not be considered an alternative to net income as an indication of our performance. In addition, these non-GAAP financial measures do not represent cash generated from operating activities in accordance with GAAP and therefore should not be considered as an alternative measure of liquidity or as indicative of cash available to fund cash needs.*

EBITDA, EBITDAre and Core EBITDAre are considered by management to be supplemental measures of our financial performance. EBITDA is defined by the Company as net income or loss computed in accordance with GAAP before interest expense, income taxes, depreciation and amortization. EBITDAre is calculated by the Company in accordance with the definition adopted by the Board of Governors of Nareit, as EBITDA plus or minus losses and gains on the disposition of depreciated property, plus casualty loss and impairment write-downs of depreciated property, with adjustments to reflect the Company's share of EBITDAre of unconsolidated entities. Core EBITDAre is the Company's EBITDAre as adjusted for non-core items outlined in the table below. By further adjusting for items that are not considered part of the Company's core business operations, Core EBITDAre can help one compare the core operating and financial performance of the Company between periods. A reconciliation of EBITDA, EBITDAre and Core EBITDAre to net income is as follows (dollars in thousands):

---

Net Debt-to-Core EBITDAre is calculated by the Company as total debt (secured and unsecured debt, and the Company's Credit Facility and commercial paper program) that is consolidated for financial reporting purposes, less consolidated cash and restricted cash, divided by annualized fourth quarter 2025 Core EBITDAre. A calculation of Net Debt-to-Core EBITDAre, as of December 31, 2025, is as follows (dollars in thousands):

---

| | |
|:---|:---|
| &nbsp;&nbsp;Total debt principal<sup>(1)</sup> | $9388152 |
| &nbsp;&nbsp;Cash and cash equivalents and restricted cash | (317065) |
| &nbsp;&nbsp;**Net debt** | $**9071087** |
| &nbsp;&nbsp;Core EBITDAre | $481187 |
| &nbsp;&nbsp;Core EBITDAre, annualized | $1924748 |
| &nbsp;&nbsp;**Net Debt-to-Core EBITDAre** | **4.7 times** |

---

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *Balance at December 31, 2025 excludes $45,620 of debt discount and deferred financing costs as reflected in unsecured debt, net, $13,588 of debt discount and deferred financing costs as reflected in notes payable, net, and $392 of commercial paper discount as reflected in unsecured credit facility and commercial paper, net on the Condensed Consolidated Balance Sheets.* 

Unencumbered NOI as calculated by the Company represents NOI generated by real estate assets unencumbered by outstanding secured notes payable as of December 31, 2025 as a percentage of total NOI generated by real estate assets. The Company believes that current and prospective unsecured creditors of the Company view Unencumbered NOI as one indication of the borrowing capacity of the Company. Therefore, when reviewed together with the Company's Interest Coverage, EBITDA and cash flow from operations, the Company believes that investors and creditors view Unencumbered NOI as a useful supplemental measure for determining the financial flexibility of an entity. A calculation of Unencumbered NOI for the year ended December 31, 2025 is as follows (dollars in thousands):

---

| | |
|:---|:---|
|  | **Full Year 2025 NOI** |
| Residential NOI: |  |
| &nbsp;&nbsp;Same Store | $1860407 |

| **Total Residential NOI** | **1989046** |
| Commercial NOI | 31903 |

As used in this definition of Cause, an act or omission to act shall be considered "willful" if done, or omitted to be done, by the grantee with knowledge and intent.

The foregoing definition does not in any way limit the Company's ability to terminate the grantee's employment at any time, nor will it limit the Company's ability to terminate the grantee's employment for poor performance or for "Cause" as defined for other purposes by the Company (e.g., with respect to other severance arrangements or guidelines).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi)subject to the provisions of Section 5(c) or Section 6(d), as applicable, to extend at any time the period in which Stock Options and Stock Appreciation Rights may be exercised;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii)at any time to adopt, alter and repeal such rules, guidelines and practices for administration of the Plan and for its own acts and proceedings as it deems advisable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii)to interpret the terms and provisions of the Plan and any Award (including related written instruments);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ix)to make all determinations it deems advisable for the administration of the Plan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(x)to decide all disputes arising in connection with the Plan; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xi)to otherwise supervise the administration of the Plan.

All decisions and interpretations of the Administrator shall be binding on all persons, including the Company and Plan grantees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Delegation of Authority to Grant Awards. Subject to applicable law, the Administrator, in its discretion, may delegate to a committee consisting of one or more officers of the Company, including the Chief Executive Officer of the Company, all or part of the Administrator's authority and duties with respect to the granting of Awards to individuals who are (i) not subject to the reporting and other provisions of Section 16 of the Exchange Act and (ii) not members of the delegated committee. Any such delegation by the Administrator shall include a limitation as to the amount of Stock underlying Awards that may be granted during the period of the delegation and shall contain guidelines as to the determination of the exercise price and the vesting criteria. The Administrator may revoke or amend the terms of a delegation at any time but such action shall not invalidate any prior actions of the Administrator's delegate or delegates that were consistent with the terms of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Award Certificate. Other than with respect to Cash-Based Awards, Awards under the Plan shall be evidenced by Award Certificates that set forth the terms, conditions and limitations for each Award which may include, without limitation, the term of an Award and the provisions applicable in the event employment or service terminates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)Indemnification. Neither the Board nor the Administrator, nor any member of either, or any delegate thereof, shall be liable for any act, omission, interpretation, construction or determination made in good faith in connection with the Plan, and the members of the Board and the Administrator (and any delegate thereof) shall be entitled in all cases to indemnification and reimbursement by the Company in respect of any claim, loss, damage or expense (including, without limitation, reasonable attorneys' fees) arising or resulting therefrom to the fullest extent permitted by law and/or under the Company's articles or bylaws or any directors' and officers' liability insurance coverage that may be in effect from time to time and/or any indemnification agreement between such individual and the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)Non-U.S. Award Recipients. Notwithstanding any provision of the Plan to the contrary, in order to comply, or facilitate compliance, with the laws in other countries in which the Company and its Subsidiaries operate or have employees or other individuals eligible for Awards, the Administrator, in its sole discretion, shall have the power and authority to: (i) determine which Affiliates shall be covered by the Plan; (ii) determine which individuals outside the United States are eligible to participate in the Plan; (iii) modify the terms and conditions of any Award granted to individuals outside the United States to comply, or facilitate compliance, with applicable non-U.S. laws; (iv) establish subplans and modify exercise procedures and other terms and procedures, to the extent the Administrator determines such actions to be necessary or advisable (and such subplans and/or modifications shall be attached to this Plan as appendices); *provided*, *however*, that no such subplans and/or modifications shall increase the share limitations contained in Section 3(a) hereof; and (v) take any action, before or after an Award is made, that the Administrator determines to be necessary or advisable to obtain approval or comply, or facilitate compliance, with any local governmental regulatory exemptions or approvals. Notwithstanding the foregoing, the Administrator may not take any actions hereunder, and no Awards shall be granted, that would violate the Exchange Act or any other applicable United States securities law, the Code or any other applicable United States governing statute or law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)Minimum Vesting Requirements. The vesting period for each Award granted under the Plan must be at least equal to the Minimum Vesting Period; provided, however, notwithstanding the foregoing, up to 5% of the shares of Stock authorized for issuance

[**Table of Contents**](#TOC)

under the Plan may be utilized for Unrestricted Stock Awards or other Awards with a vesting period that is less than the Minimum Vesting Period (each such Award, an "***Excepted Award***"). Notwithstanding the foregoing, (x) in addition to Excepted Awards, the Administrator may grant Awards that vest (or permit previously granted Awards to vest) within the Minimum Vesting Period (i) if such Awards are granted as substitute Awards in replacement of other Awards (or awards previously granted by an entity being acquired (or assets of which are being acquired)) that were scheduled to vest within the Minimum Vesting Period or (ii) if such Awards are being granted in lieu of fully vested cash compensation and (y) nothing in this Section 2(f) shall limit the Administrator's authority to provide for the accelerated vesting of Awards in the terms of an Award Certificate or as permitted in Section 2(b)(v) above.

SECTION 3. STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Stock Issuable. Subject to adjustment as provided in this Section 3, the maximum number of shares of Stock reserved and available for issuance under the Plan shall be 4,000,000 shares less one share for every one share of Stock subject to an award granted under the Prior Plan after March 15, 2026. For purposes of this limitation, the shares of Stock underlying any awards under the Plan and under the Prior Plan that are forfeited, canceled, cash-settled or otherwise terminated (other than by exercise) will be added back to the shares of Stock available for issuance under the Plan and, to the extent permitted under Section 422 of the Code and the regulations promulgated thereunder, the shares of Stock that may be issued as Incentive Stock Options. Notwithstanding the foregoing, the following shares will not be added to the shares authorized for grant under the Plan: (i) shares tendered or held back upon exercise of an Option or settlement of an Award to cover the exercise price or tax withholding and (ii) shares subject to a Stock Appreciation Right that are not issued in connection with the stock settlement of the Stock Appreciation Right upon exercise thereof. In the event the Company repurchases shares of Stock on the open market, such shares will not be added to the shares of Stock available for issuance under the Plan. Subject to such overall limitations, shares of Stock may be issued up to such maximum number pursuant to any type or types of Award; provided, however, that no more than 2,000,000 shares of the Stock may be issued in the form of Incentive Stock Options. The shares available for issuance under the Plan may be authorized but unissued shares of Stock, treasury Stock or shares of Stock reacquired by the Company. Upon effectiveness of the Plan, no new awards shall be granted under the Prior Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Substitute Awards. Substitute Awards shall not reduce the shares of Stock authorized for grant under the Plan, nor shall shares subject to a Substitute Award be added to the shares of Stock available for Awards under the Plan as provided in Section 3(a) above. Additionally, in the event that a company acquired by the Company or any Affiliate or with which the Company or any Affiliate combines has shares available under a pre-existing plan approved by stockholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the shares authorized for grant under the Plan (and shares subject to such Awards shall not be added to the shares available for Awards under the Plan as provided in Section 3(a) above); provided that Awards using such available shares shall not be made after the date awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not employees or directors prior to such acquisition or combination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Changes in Stock. Subject to Section 3(d) hereof, if, as a result of any reorganization, recapitalization, reclassification, stock dividend, extraordinary cash dividend, stock split, reverse stock split or other similar change in the Company's capital stock, the outstanding shares of Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Stock or other securities, or, if, as a result of any merger or consolidation or sale of all or substantially all of the assets of the Company, the outstanding shares of Stock are converted into or exchanged for securities of the Company or any successor entity (or a parent or subsidiary thereof), the Administrator shall make an appropriate or proportionate adjustment in (i) the maximum number of shares reserved for issuance under the Plan, including the maximum number of shares that may be issued in the form of Incentive Stock Options, (ii) the number and kind of shares or other securities subject to any then outstanding Awards under the Plan, (iii) the repurchase price, if any, per share subject to each outstanding Restricted Stock Award and (iv) the exercise price for each share subject to any then outstanding Stock Options and Stock Appreciation Rights under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of shares subject to Stock Options and Stock Appreciation Rights) as to which such Stock Options and Stock Appreciation Rights remain exercisable. The Administrator shall also make equitable or proportionate adjustments in the number of shares subject to outstanding Awards and the exercise price and the terms of outstanding Awards to take into consideration cash dividends paid other than in the ordinary course or any other extraordinary corporate event. The adjustment by the Administrator shall be final, binding and conclusive. No fractional shares of Stock shall be issued under the Plan resulting from any such adjustment, but the Administrator in its discretion may make a cash payment in lieu of fractional shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Mergers and Other Transactions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Except as the Administrator may otherwise specify with respect to particular Awards in the relevant Award Certificate, in the case of and subject to the consummation of a Sale Event, the parties thereto may cause the assumption or continuation of Awards theretofore granted by the successor entity, or the substitution of such Awards with new Awards of the successor entity or parent thereof, with appropriate adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree. In the event that a grantee's Service Relationship with the Company (or its successor) is terminated by the Company (or its successor) without Cause or by the grantee for Good Reason either upon or within 24 months following a Sale Event, except as the Administrator may otherwise specify with respect to particular Awards in the relevant Award Certificate, all Awards held by such grantee that are assumed, continued or substituted in connection with a Sale Event will become fully vested and exercisable or nonforfeitable on the date of termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)To the extent the parties to such Sale Event do not provide for the assumption, continuation or substitution of Awards, upon the effective time of the Sale Event, the Plan and all outstanding Awards granted hereunder will terminate. In such case, except as may be otherwise provided in the relevant Award Certificate, all Awards with time-based vesting conditions or restrictions that are not vested and/or exercisable immediately prior to the effective time of the Sale Event will become fully vested and exercisable or nonforfeitable as of the effective time of the Sale Event, and all Awards with conditions and restrictions relating to the attainment of performance goals will become vested and exercisable or nonforfeitable in connection with a Sale Event in the Administrator's discretion or to the extent specified in the relevant Award Certificate. In the event of such termination, (i) the Company shall have the option (in its sole discretion) to make or provide for a payment, in cash or in kind, to the grantees holding Options and Stock Appreciation Rights, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the Sale Price multiplied by the number of shares of Stock subject to outstanding Options and Stock Appreciation Rights (to the extent then exercisable at prices not in excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding Options and Stock Appreciation Rights (provided that, in the case of an Option or Stock Appreciation Right with an exercise price equal to or greater than the Sale Price, such Option or Stock Appreciation Right will be cancelled for no consideration); or (ii) each grantee will be permitted, within a specified period of time prior to the consummation of the Sale Event as determined by the Administrator, to exercise all outstanding Options and Stock Appreciation Rights (to the extent then exercisable) held by such grantee. In the event of such termination, the Company will also have the option (in its sole discretion) to make or provide for a payment, in cash or in kind, to the grantees holding other Awards in an amount equal to the Sale Price multiplied by the number of vested shares of Stock under such Awards.

SECTION 4. ELIGIBILITY

Grantees under the Plan will be such officers, employees, Non-Employee Directors or Consultants of the Company or its Affiliates as are selected from time to time by the Administrator in its sole discretion; provided that Awards may not be granted to officers, employees, Non-Employee Directors or Consultants who are providing services only to any "parent" of the Company, as such term is defined in Rule 405 of the Act, unless (i) the stock underlying the Awards is treated as "service recipient stock" under Section 409A or (ii) the Company has determined that such Awards are exempt from or otherwise comply with Section 409A.

SECTION 5. STOCK OPTIONS

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Award of Stock Options. The Administrator may grant Stock Options under the Plan, subject to such restrictions and conditions as the Administrator determines. Conditions may be based on continuing employment (or other Service Relationship) and/or achievement of pre-established performance goals and objectives. Stock Options granted under the Plan may be either Incentive Stock Options or Non-Qualified Stock Options. Incentive Stock Options may be granted only to employees of the Company or any Subsidiary that is a "subsidiary corporation" within the meaning of Section 424(f) of the Code. To the extent that any Option does not qualify as an Incentive Stock Option, it will be deemed a Non-Qualified Stock Option. Stock Options shall be subject to the following terms and conditions and will contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator deems desirable. If the Administrator so determines, Stock Options may be granted in lieu of cash compensation at the grantee's election, subject to such terms and conditions as the Administrator may establish.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Exercise Price. The exercise price per share for the Stock covered by a Stock Option will be determined by the Administrator at the time of grant but may not be less than 100% of the Fair Market Value on the date of grant. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the exercise price of such Incentive Stock Option may be not less than 110% of the Fair Market Value on the grant date. Notwithstanding the foregoing, Stock Options may be granted with an exercise price per share that is less than 100% of the Fair Market Value on the date of grant (i) pursuant to a transaction described in, and in a manner consistent

with, Section 424(a) of the Code, (ii) to individuals who are not subject to U.S. income tax on the date of grant or (iii) if the Stock Option is otherwise exempt from or compliant with Section 409A.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Option Term. The term of each Stock Option will be fixed by the Administrator, but no Stock Option shall be exercisable more than ten years after the date the Stock Option is granted. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the term of such Stock Option may be no more than five years from the date of grant. Notwithstanding the foregoing, to the extent permitted by Section 409A, in the event that on the last business day of the term of a Stock Option other than an Incentive Stock Option (x) the exercise of the Stock Option is prohibited by applicable law or (y) Stock may not be purchased or sold by the holder of such Stock Option due to the "black-out period" of a Company policy or a "lock-up" agreement undertaken in connection with an issuance of securities by the Company, the term of the Stock Option will be extended to the date that is 30 days following the end of the legal prohibition, black-out period or lock-up agreement and provided further that no extension will be made if the exercise price of such Stock Option at the date the initial term would otherwise expire is equal to or in excess of the Fair Market Value of a share of Stock on such date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Exercisability; Rights of a Stockholder. Stock Options shall become exercisable at such time or times, whether or not in installments, as determined by the Administrator at or after the grant date. A grantee will have the rights of a stockholder only as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)Method of Exercise. Stock Options may be exercised in whole or in part, by giving written or electronic notice of exercise to the Company, specifying the number of shares to be purchased. Payment of the purchase price may be made by one or more of the following methods except to the extent otherwise provided in the Award Certificate:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)In cash, by certified or bank check or other instrument acceptable to the Administrator;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Through the delivery (or attestation to the ownership following such procedures as the Company may prescribe) of shares of Stock that are owned by the grantee and not then subject to restrictions under any Company plan. Such surrendered shares shall be valued at Fair Market Value on the exercise date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)By the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company for the purchase price; provided that in the event the grantee chooses to pay the purchase price as so provided, the grantee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Company reasonably prescribes as a condition of such payment procedure; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)With respect to Stock Options that are not Incentive Stock Options, by a "net exercise" arrangement pursuant to which the Company will reduce the number of shares of Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price.

Payment instruments will be received subject to collection. The transfer to the grantee on the records of the Company or of the transfer agent of the shares of Stock to be purchased pursuant to the exercise of a Stock Option will be contingent upon receipt from the grantee (or a purchaser acting in the grantee's stead in accordance with the provisions of the Stock Option) by the Company of the full purchase price for such shares and the fulfillment of any other requirements contained in the Award Certificate or applicable provisions of laws (including the satisfaction of any withholding taxes that the Company is obligated to withhold with respect to the grantee). In the event an grantee chooses to pay the purchase price by previously-owned shares of Stock through the attestation method, the number of shares of Stock transferred to the grantee upon the exercise of the Stock Option shall be net of the number of attested shares. In the event that the Company establishes, for itself or using the services of a third party, an automated system for the exercise of Stock Options, such as a system using an internet website or interactive voice response, then the paperless exercise of Stock Options may be permitted through the use of such an automated system.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)Annual Limit on Incentive Stock Options. To the extent required for "incentive stock option" treatment under Section 422 of the Code, the aggregate Fair Market Value (determined as of the time of grant) of the shares of Stock with respect to which Incentive Stock Options granted under this Plan and any other plan of the Company or its parent and subsidiary corporations become exercisable for the first time by an grantee during any calendar year may not exceed $100,000. To the extent that any Stock Option exceeds this limit, it will constitute a Non-Qualified Stock Option.

SECTION 6. STOCK APPRECIATION RIGHTS

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Award of Stock Appreciation Rights. The Administrator may grant Stock Appreciation Rights under the Plan, subject to such restrictions and conditions as the Administrator determines. Conditions may be based on continuing employment (or other Service Relationship) and/or achievement of pre-established performance goals and objectives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Exercise Price of Stock Appreciation Rights. The exercise price of a Stock Appreciation Right shall not be less than 100% of the Fair Market Value of the Stock on the date of grant. Notwithstanding the foregoing, Stock Appreciation Rights may be granted with an exercise price per share that is less than 100% of the Fair Market Value on the date of grant (i) pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code, (ii) to individuals who are not subject to U.S. income tax on the date of grant or (iii) if the Stock Appreciation Right is otherwise exempt from or compliant with Section 409A.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Grant and Exercise of Stock Appreciation Rights. Stock Appreciation Rights may be granted by the Administrator independently of any Stock Option.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Terms and Conditions of Stock Appreciation Rights. Stock Appreciation Rights shall be subject to such terms and conditions as determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. The term of a Stock Appreciation Right may not exceed ten years. Notwithstanding the foregoing, to the extent permitted by Section 409A, in the event that on the last business day of the term of a Stock Appreciation Right (x) the exercise of the Stock Appreciation Right is prohibited by applicable law or (y) shares may not be purchased or sold by the holder of such Stock Appreciation Right due to the "black-out period" of a Company policy or a "lock-up" agreement undertaken in connection with an issuance of securities by the Company, the term of the Stock Appreciation Right will be extended to the date that is 30 days following the end of the legal prohibition, black-out period or lock-up agreement and provided further that no extension will be made if the exercise price of such Stock Appreciation Right at the date the initial term would otherwise expire is equal to or in excess of the Fair Market Value of a share of Stock on such date.

SECTION 7. RESTRICTED STOCK AWARDS

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Nature of Restricted Stock Awards. The Administrator may grant Restricted Stock Awards under the Plan, subject to such restrictions and conditions as the Administrator determines. Such conditions may be based on continuing employment (or other Service Relationship) and/or achievement of pre-established performance goals and objectives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Rights as a Stockholder. Upon the grant of the Restricted Stock Award and payment of any applicable purchase price, a grantee will have the rights of a stockholder with respect to the voting of the Restricted Shares and receipt of dividends. Unless the Administrator otherwise determines, (i) uncertificated Restricted Shares will be accompanied by a notation on the records of the Company or the transfer agent to the effect that they are subject to forfeiture until such Restricted Shares are vested as provided in Section 7(d) below and (ii) certificated Restricted Shares will remain in the possession of the Company until such Restricted Shares are vested as provided in Section 7(d) below, and the grantee will be required, as a condition of the grant, to deliver to the Company such instruments of transfer as the Administrator prescribes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Restrictions. Restricted Shares may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided herein or in the Restricted Stock Award Certificate. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 17 below, in writing after the Award is issued, if a grantee's employment (or other Service Relationship) with the Company and its Affiliates terminates for any reason, any Restricted Shares that have not vested at the time of termination shall automatically and without any requirement of notice to such grantee from or other action by or on behalf of, the Company be deemed to have been reacquired by the Company at its original purchase price (if any) from such grantee or such grantee's legal representative simultaneously with such termination of employment (or other Service Relationship), and thereafter shall cease to represent any ownership of the Company by the grantee or rights of the grantee as a stockholder. Following such deemed reacquisition of Restricted Shares that are represented by physical certificates, a grantee shall surrender such certificates to the Company upon request without consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Vesting of Restricted Shares. The Administrator will specify the date or dates and/or the attainment of pre-established performance goals, objectives and/or other conditions on which the non-transferability of the Restricted Shares and the Company's right of repurchase or forfeiture shall lapse. Subsequent to such date or dates and/or the attainment of such pre-established performance goals,

objectives and/or other conditions, the shares on which all restrictions have lapsed will no longer be Restricted Shares and will be deemed "vested."

SECTION 8. RESTRICTED STOCK UNITS

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Nature of Restricted Stock Units. The Administrator may grant Restricted Stock Units under the Plan, subject to such restrictions and conditions as the Administrator determines. Conditions may be based on continuing employment (or other Service Relationship) and/or achievement of pre-established performance goals, objectives and/or other conditions. Restricted Stock Units may be settled in shares of Stock (and/or cash, to the extent explicitly provided for in the Award Certificate) upon the satisfaction of such restrictions and conditions. Except in the case of Restricted Stock Units with a deferred settlement date that complies with Section 409A, at the end of the vesting period, the Restricted Stock Units, to the extent vested, will be settled in the form of shares of Stock (or cash, to the extent explicitly provided for in the applicable Award Certificate). Restricted Stock Units with deferred settlement dates are subject to Section 409A and will contain such additional terms and conditions as the Administrator determines in its sole discretion in order to comply with the requirements of Section 409A.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Election to Receive Restricted Stock Units in Lieu of Compensation. The Administrator may, in its sole discretion, permit a grantee to elect to receive a portion of future cash compensation or other Award otherwise due to such grantee in the form of an award of Restricted Stock Units. Any such election shall be made in writing and shall be delivered to the Company no later than the date specified by the Administrator and in accordance with Section 409A and such other rules and procedures established by the Administrator. Any such future cash compensation that the grantee elects to defer will be converted to a fixed number of Restricted Stock Units based on the Fair Market Value of Stock on the date the compensation would otherwise have been paid to the grantee if such payment had not been deferred as provided herein. The Administrator has the sole right to determine whether and under what circumstances to permit such elections and to impose such limitations and other terms and conditions thereon as the Administrator deems appropriate. Any Restricted Stock Units that are elected to be received in lieu of cash compensation will be fully vested, unless otherwise provided in the Award Certificate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Rights as a Stockholder. A grantee will have the rights as a stockholder only as to shares of Stock acquired by the grantee upon settlement of Restricted Stock Units; provided, however, that the grantee may be credited with Dividend Equivalent Rights with respect to the grantee's Restricted Stock Units, subject to the provisions of Section 11 and such terms and conditions as the Administrator determines.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Termination. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 17 below, in writing after the Award is issued, a grantee's right in all Restricted Stock Units that have not vested will automatically terminate upon the grantee's termination of employment (or cessation of Service Relationship) with the Company and its Affiliates for any reason.

SECTION 9. UNRESTRICTED STOCK AWARDS

Grant or Sale of Unrestricted Stock. Subject to the limitations set forth in Section 2(g), the Administrator may grant (or sell at par value or such higher purchase price determined by the Administrator) an Unrestricted Stock Award under the Plan. An Unrestricted Stock Award is an Award pursuant to which the grantee receives shares of Stock free of any restrictions under the Plan. Unrestricted Stock Awards may be granted in respect of past services or other valid consideration, or in lieu of cash compensation due to such grantee.

SECTION 10. CASH-BASED AWARDS

Grant of Cash-Based Awards. The Administrator may grant Cash-Based Awards under the Plan. The Administrator shall determine the maximum duration of the Cash-Based Award, the amount of cash to which the Cash-Based Award pertains, the conditions upon which the Cash-Based Award will become vested or payable and such other provisions as the Administrator determines. Each Cash-Based Award shall specify a cash-denominated payment amount, formula or payment ranges as determined by the Administrator. Payment, if any, with respect to a Cash-Based Award shall be made in accordance with the terms of the Award and may be made in cash.

SECTION 11. DIVIDEND EQUIVALENT RIGHTS

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Dividend Equivalent Rights. The Administrator may grant Dividend Equivalent Rights under the Plan. A Dividend Equivalent Right may be granted hereunder to any grantee as a component of an award of Restricted Stock Units, Other Equity-Based Awards or as a freestanding award. The terms and conditions of Dividend Equivalent Rights will be specified in the Award Certificate. Dividend equivalents credited to the holder of a Dividend Equivalent Right may be paid currently or may be deemed to be reinvested in additional shares of Stock, which may thereafter accrue additional equivalents. Any such reinvestment will be at Fair Market Value on the date of reinvestment or such other price as may then apply under a dividend reinvestment plan sponsored by the Company, if any. Dividend Equivalent Rights may be settled in cash or shares of Stock or a combination thereof, in a single installment or installments. A Dividend Equivalent Right granted as a component of an Award of Restricted Stock Units or Other Equity-Based Award may be settled only upon settlement or payment of, or lapse of restrictions on, such other Award, and such Dividend Equivalent Right will expire or be forfeited or annulled under the same conditions as such other Award. Notwithstanding anything to the contrary, no Dividend Equivalent Rights shall be granted with respect to any Stock Options or Stock Appreciation Rights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Termination. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 17 below, in writing after the Award is issued, a grantee's rights in all Dividend Equivalent Rights will automatically terminate upon the grantee's termination of employment (or cessation of Service Relationship) with the Company and its Affiliates for any reason.

SECTION 12. OTHER EQUITY-BASED Awards

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)The Administrator shall have the right to grant Other Equity-Based Awards, with any shares of Stock being issued in connection with the conversion of (or other distribution on account of) an interest granted under the authority of this Section 12 to be subject to Section 3 and the other provisions of the Plan.

SECTION 13. Transferability of Awards

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Transferability. Except as provided in Section 13(b) below, during a grantee's lifetime, such grantee's Awards are exercisable only by the grantee, or by the grantee's legal representative or guardian in the event of the grantee's incapacity. No Awards may be sold, assigned, transferred or otherwise encumbered or disposed of by a grantee other than by will or by the laws of descent and distribution or pursuant to a domestic relations order. No Awards will be subject, in whole or in part, to attachment, execution or levy of any kind, and any purported transfer in violation hereof shall be null and void.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Administrator Action. Notwithstanding Section 13(a), the Administrator, in its discretion, may provide either in the Award Certificate regarding a given Award or by subsequent written approval that the grantee may transfer the grantee's Awards (other than Incentive Stock Options) to the grantee's immediate family members, to trusts for the benefit of such family members or to partnerships in which such family members are the only partners, provided that the transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Award. In no event may an Award be transferred by a grantee for value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Family Member. For purposes of Section 13(b), "family member" means a grantee's child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law, including adoptive relationships, any person sharing the grantee's household (other than a tenant of the grantee), a trust in which these persons (or the grantee) have more than 50% of the beneficial interest, a foundation in which these persons (or the grantee) control the management of assets and any other entity in which these persons (or the grantee) own more than 50% of the voting interests.

SECTION 14. TAX WITHHOLDING

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Payment by Grantee. Each grantee must, no later than the date as of which the value of an Award or of any Stock or other amounts received thereunder first becomes includable in the gross income of the grantee for income tax purposes, pay to the Company, or make arrangements satisfactory to the Administrator regarding payment of, any federal, state, local, non-U.S. or other taxes of any kind required by law to be withheld by the Company or any applicable Affiliate with respect to such income. The Company and its Affiliates shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the grantee. The Company's obligation to deliver evidence of book entry (or stock certificates) to any grantee is subject to and conditioned on tax withholding obligations being satisfied by the grantee.

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Payment in Stock. The Administrator may require the Company or any Affiliate's tax withholding obligation to be satisfied, in whole or in part, by the Company withholding from shares of Stock to be issued pursuant to any Award a number of shares with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding amount due; provided, however, that the amount withheld does not exceed the maximum statutory tax rate or such lesser amount as is necessary to avoid liability accounting treatment. For purposes of share withholding, the Fair Market Value of withheld shares will be determined in the same manner as the value of Stock includible in income of the grantees. The Administrator may also require the Company or any Affiliate's tax withholding obligation to be satisfied, in whole or in part, by an arrangement whereby a certain number of shares of Stock issued pursuant to any Award are immediately sold and proceeds from such sale are remitted to the Company or the applicable Affiliate in an amount that would satisfy the withholding amount due.

SECTION 15. Section 409A awards

Awards are intended to be exempt from Section 409A to the greatest extent possible and to otherwise comply with Section 409A. The Plan and all Awards shall be interpreted in accordance with such intent. To the extent that any Award is determined to constitute "nonqualified deferred compensation" within the meaning of Section 409A (a "***409A Award***"), the Award shall be subject to such additional rules and requirements as specified by the Administrator from time to time in order to comply with Section 409A. If any amount under a 409A Award is payable upon a "separation from service" (within the meaning of Section 409A) to a grantee who is then considered a "specified employee" (within the meaning of Section 409A), then no such payment may be made prior to the date that is the earlier of (i) six months and one day after the grantee's separation from service or (ii) the grantee's death, but only to the extent such delay is necessary to prevent such payment from being subject to interest, penalties and/or additional tax imposed pursuant to Section 409A. Further, the settlement of any 409A Award may not be accelerated except to the extent permitted by Section 409A. The Company makes no representation that any or all of the payments or benefits described in the Plan will be exempt from or comply with Section 409A and makes no undertaking to preclude Section 409A from applying to any such payment. The grantee is solely responsible for the payment of any taxes and penalties incurred with respect to Awards under the Plan, including under Section 409A.

SECTION 16. TERMINATION OF SERVICE RELATIONSHIP, TRANSFER, LEAVE OF ABSENCE, ETC.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Termination of Service Relationship. If the grantee's Service Relationship is with an Affiliate and such Affiliate ceases to be an Affiliate, the grantee will be deemed to have terminated the grantee's Service Relationship for purposes of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)For purposes of the Plan, the following events will not be deemed a termination of a Service Relationship:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)a transfer of employment from the Company to an Affiliate or vice versa, or from one Affiliate to another;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)an approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the employee's right to re-employment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Administrator otherwise so provides in writing; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)the transfer in status from one eligibility category under Section 4 hereof to another category.

SECTION 17. AMENDMENTS AND TERMINATION

The Board may, at any time, amend or discontinue the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the purpose of satisfying changes in law or for any other lawful purpose, but no such action may materially and adversely affect rights under any outstanding Award without the holder's consent. Except as provided in Section 3(c) or 3(d), without prior stockholder approval, in no event may the Administrator exercise its discretion to reduce the exercise price of outstanding Stock Options or Stock Appreciation Rights or effect repricing through cancellation and re-grants or cancellation of Stock Options or Stock Appreciation Rights in exchange for cash or other Awards or take any other action with respect to a Stock Option or Stock Appreciation Right that would be treated as a repricing under the rules and regulations of the principal U.S. national securities exchange on which the Stock is listed. To the extent determined by the Administrator to be required under the rules of any securities exchange or market system on which the Stock is listed, or by the Code to ensure that Incentive Stock Options granted under the Plan are qualified under Section 422 of the Code, Plan amendments shall be subject to approval by Company stockholders entitled to vote at a meeting of stockholders. Nothing in this Section 17 shall limit the Administrator's authority to take any action permitted pursuant to Section 3(c) or 3(d).

SECTION 18. STATUS OF PLAN

With respect to the portion of any Award that has not been exercised and any payments in cash, Stock or other consideration not received by a grantee, a grantee shall have no rights greater than those of a general creditor of the Company unless the Administrator otherwise expressly determines in connection with any Award or Awards. In its sole discretion, the Administrator may authorize the creation of trusts or other arrangements to meet the Company's obligations to deliver Stock or make payments with respect to Awards hereunder, provided that the existence of such trusts or other arrangements is consistent with the foregoing sentence.

SECTION 19. GENERAL PROVISIONS

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)No Distribution. The Administrator may require each person acquiring Stock pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the shares without a view to distribution thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Issuance of Stock. To the extent certificated, stock certificates to grantees under this Plan shall be deemed delivered for all purposes when the Company or a stock transfer agent of the Company has mailed such certificates in the United States mail, addressed to the grantee, at the grantee's last known address on file with the Company. Uncertificated Stock will be deemed delivered for all purposes when the Company or a Stock transfer agent of the Company has given to the grantee by electronic mail (with proof of receipt) or by United States mail, addressed to the grantee, at the grantee's last known address on file with the Company, notice of issuance and recorded the issuance in its records (which may include electronic "book entry" records). Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any evidence of book entry or certificates evidencing shares of Stock pursuant to the exercise or settlement of any Award, unless and until the Administrator has determined, with advice of counsel (to the extent the Administrator deems such advice necessary or advisable), that the issuance and delivery is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any exchange on which the shares of Stock are listed, quoted or traded. Any Stock issued pursuant to the Plan will be subject to any stop-transfer orders and other restrictions as the Administrator deems necessary or advisable to comply with federal, state, or foreign jurisdiction securities or other laws, rules and quotation system on which the Stock is listed, quoted or traded. The Administrator may place legends on any Stock certificate or notations on any book entry to reference restrictions applicable to the Stock. In addition to the terms and conditions provided herein, the Administrator may require that an individual make such reasonable covenants, agreements and representations as the Administrator, in its discretion, deems necessary or advisable in order to comply with any such laws, regulations, or requirements. The Administrator has the right to require any individual to comply with any timing or other restrictions with respect to the settlement or exercise of any Award, including a window-period limitation, as may be imposed in the discretion of the Administrator.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)No Fractional Shares. No fractional shares of Stock may be issued or delivered pursuant to the Plan or any Award, and the Administrator will determine whether cash, other securities or other property will be paid or transferred in lieu of any fractional shares, or whether such fractional shares or any rights thereto shall be canceled, terminated or otherwise eliminated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Stockholder Rights. Except as otherwise provided in this Plan or an Award Certificate, until Stock is deemed delivered in accordance with Section 19(b), no right to vote or receive dividends or any other rights of a stockholder will exist with respect to shares of Stock to be issued in connection with an Award, notwithstanding the exercise of a Stock Option or any other action by the grantee with respect to an Award; provided, however, that if the record date for a dividend on the Stock occurs after exercise of an option or after Stock otherwise should have been delivered to a grantee pursuant to the terms of the Plan and an Award Agreement, such dividend will be delivered to the grantee promptly upon payment to the Company's stockholders generally.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)Other Compensation Arrangements; No Employment Rights. Nothing contained in this Plan shall prevent the Board from adopting other or additional compensation arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases. The adoption of this Plan and the grant of Awards do not confer upon any grantee any right to continued employment or other Service Relationship with the Company or any Affiliate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)Trading Policy Restrictions. Awards under the Plan shall be subject to the Company's insider trading policies and procedures, as in effect from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)Clawback Policy. All Awards are subject to reduction, cancellation, forfeiture or recoupment to the extent necessary to comply with (i) any clawback, forfeiture or other similar policy adopted by the Board or Administrator and as in effect from time to time, including the Company's Compensation Recovery Policy (as such policy may be amended and/or restated from time to time), and (ii) applicable law. Further, to the extent that the grantee receives any amount in excess of the amount that the grantee should otherwise
