Any statements in the discussion below and elsewhere in this Proxy Statement about expectations, beliefs, plans, objectives, assumptions, or future events or performance of the Company are not historical facts and are forward-looking statements. Such forward-looking statements include, without limitation, statements about our stockholder engagement program; the execution of our corporate growth strategy and strategic priorities for 2026, including the leveraging of our technology platform and pipeline to forge additional partnerships and the advancement of our technology platform and early-stage pipeline; our ability to deliver long-term growth and achieve our profitability goals; our efforts to make a positive impact on global health and operate in a sustainable and inclusive manner; our compensation program goals; and the impact of compensation paid to our named executive officers to encourage the achievement of our strategic priorities and milestones in 2025 and beyond; and other matters referenced herein. Generally, forward-looking statements can be identified through the use of words or phrases such as "believe," "may," "could," "will," "would," "possible," "can," "estimate," "continue," "ongoing," "consider," "anticipate," "intend," "seek," "plan," "project," "expect," "should," "would," "aim," or "assume," the negative of these terms, or other comparable terminology, although not all forward-looking statements contain these words.

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs and expectations about the future of our business, future plans and strategies, projections, anticipated events and trends, the economy, and other future conditions. Forward-looking statements involve estimates, assumptions, risks, and uncertainties that could cause actual results or outcomes to differ materially from those expressed or implied in any forward-looking statements, and, therefore, you should not place considerable reliance on any such forward-looking statements. Such risks and uncertainties include, without limitation, the ability to successfully and timely obtain and maintain full U.S. FDA licensure or foreign regulatory approvals necessary to manufacture, market, distribute, or deliver Nuvaxovid; the impact of delays in obtaining regulatory approval, including regulatory decisions impacting labeling, approval or authorization, including the scope of the indicated population, product dosage, manufacturing processes, shelf life, safety, for our product candidates; challenges in conducting the postmarketing commitment ("PMC") study, our ability to obtain adequate additional funding to maintain our current level of operations and fund the further development of our vaccine candidates; challenges related to our partnership with Sanofi, including collaboration on the Nuvaxovid PMC, and in pursuing additional partnership opportunities; challenges satisfying, alone or together with partners, various safety, efficacy, and product characterization requirements, including those related to process qualification, assay validation and stability testing, necessary to satisfy applicable

**Proxy Summary**

**Executive Compensation Highlights**

**STOCKHOLDER ENGAGEMENT**

&nbsp;&nbsp;**Stockholder Engagement Highlights**<br>We value engagement with our stockholders. We communicate regularly with stockholders and other stakeholders throughout the year, and the Board considers a range of stakeholder perspectives in discharging its oversight responsibilities.<br>&nbsp;&nbsp;&nbsp;&nbsp;• In 2025, we received the support of 72.3% of votes cast for our "say-on-pay" proposal and we looked to enhance our Stockholder Outreach program. We made a concerted effort to better understand stockholders' views on the 2025 say-on-pay vote, actively soliciting feedback throughout 2025.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Topics discussed in connection with our Stockholder Outreach program included executive compensation, including the design of a compensation policy that effectively incentivizes and rewards executives through defined goals and strategic performance metrics.<br>&nbsp;&nbsp;&nbsp;&nbsp;• During 2025, we contacted each of our top 20 institutional stockholders, representing approximately 78% of our institutional ownership and 46% of shares outstanding. The Board and the Compensation Committee discussed the feedback from our stockholders on executive compensation. Stockholders who engaged with us expressed favorable views on the structure, design and governance of our executive compensation, and no stockholders suggested or recommended changes to the structure or elements of our compensation program.<br>

**COMPENSATION PHILOSOPHY AND OBJECTIVES**

Our compensation program is designed to attract, retain, and reward a high-performance workforce in an extremely competitive recruitment and retention market to achieve Novavax's mission, vision, and goals.

**NOVAVAX, INC.** 2026 PROXY STATEMENT<sub>7</sub>

**BOARD OF DIRECTORS AND CORPORATE GOVERNANCE**<br>

**Proposal 1—Election of Directors**

In accordance with the Company's charter, the Board of Directors (the "Board") may consist of no fewer than three directors, with the specific number to be authorized by the Board from time to time at its discretion. The Board is presently authorized to consist of nine members, and currently includes the following nine individuals:

---

| | | |
|:---|:---|:---|
| **Class I Directors**<br>**Terms expiring at the 2026 Annual Meeting** | **Class II Directors**<br>**Terms expiring at the 2027 Annual Meeting** | **Class III Directors**<br>**Terms expiring at the 2028 Annual Meeting** |
| &nbsp;&nbsp;&nbsp;&nbsp;• John C. Jacobs<br>&nbsp;&nbsp;&nbsp;&nbsp;• Gregg H. Alton, J.D.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Richard J. Rodgers | &nbsp;&nbsp;&nbsp;&nbsp;• Richard H. Douglas, Ph.D.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Margaret G. McGlynn, R. Ph.<br>&nbsp;&nbsp;&nbsp;&nbsp;• David Mott, *Chairman of the Board* | &nbsp;&nbsp;&nbsp;&nbsp;• Rachel K. King<br>&nbsp;&nbsp;&nbsp;&nbsp;• John W. Shiver, Ph.D.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Charles W. Newton |

---

Members of the Board are divided into three classes, designated as Class I, Class II, and Class III, each serving staggered three-year terms. The terms of the Class I directors expire at the 2026 Annual Meeting. The terms of the Class II and Class III directors will expire at the 2027 and 2028 Annual Meetings of Stockholders, respectively. A director of any class who is elected by the Board to fill a vacancy resulting from an increase in the number of directors holds office for the remaining term of the class to which he or she is elected. A director who is elected by the Board to fill a vacancy arising in any other manner holds office for the remaining term of his or her predecessor. Directors elected by the stockholders at an annual meeting to succeed those whose terms expire at the meeting are of the same class as the directors they succeed and are elected for a term to expire at the third Annual Meeting of Stockholders after their election and until their successors are duly elected and qualified.

The Company did not receive any valid nominations from stockholders for the 2026 Annual Meeting.

In the event of any increase or decrease in the authorized number of directors, the newly created or eliminated directorships must be apportioned by the Board among the three classes to ensure that no one class has more than one director more than any other class, unless otherwise determined by a resolution of the Board. However, since existing directors cannot move across classes, the number of directors continuing in office following the Annual Meeting, as well as the nominees for election at the Annual Meeting, including their ages and positions as of April 23, 2026, are reflected below followed by biographical information for each such director and nominee.

| ![02_NVVX_Ticker_Check Boxed_wBG.jpg](nvax-20260427_g45.jpg) | **The Board recommends that stockholders vote**<br>**FOR the election of the nominees.** |

**Nominees for Election as Class I Directors**

After recommendation by the Nominating and Corporate Governance Committee, the Board has nominated John C. Jacobs, Gregg H. Alton, J.D., and Richard J. Rodgers for election as Class I directors of the Company at the Annual Meeting. If elected, each such nominee will serve until the expiration of their term at the 2029 Annual Meeting of Stockholders and until their successor is elected and qualified and until their earlier death, resignation, or removal. Mr. Jacobs, Mr. Alton, and Mr. Rodgers have consented to being named in this Proxy Statement and to serve if elected. The Board has no reason to believe that Mr. Jacobs, Mr. Alton, or Mr. Rodgers will be unable or unwilling to serve if elected. If any nominee becomes unavailable to serve as a director, the persons named in the proxy will vote the proxy for a substitute nominee or nominees as they, in their discretion, shall determine.

**NOVAVAX, INC.** 2026 PROXY STATEMENT<sub>13</sub>

**Board of Directors and Corporate Governance**

**Information Regarding the Board and Corporate Governance Matters**

The Board has affirmatively determined, upon the recommendation by the Nominating and Corporate Governance Committee, that all of the members of the Board qualify as "independent" directors as defined in the listing standards of Nasdaq Stock Market LLC ("Nasdaq"), except Mr. Jacobs. Mr. Jacobs is currently the President and Chief Executive Officer of the Company.

During 2025, the Board met four times. Each of our incumbent directors attended at least 75% of the aggregate of the total number of meetings of the Board they were eligible to attend, as well as the total number of meetings held by all committees on which they served.

Recognizing that director attendance at the Company's Annual Meeting of Stockholders provides stockholders with an opportunity to communicate with members of the Board, the Company strongly encourages (but does not require) members of the Board to attend such meetings. All of the then-serving Board members attended the 2025 Annual Meeting of Stockholders.

**Board Leadership Structure and Role in Risk Oversight**

Our Corporate Governance Guidelines provide our Board with flexibility to combine or separate the positions of Chairman of the Board and Chief Executive Officer in accordance with its business judgment after considering relevant factors, including the specific needs of the business and what is in the best interests of the Company's stockholders.

If the Chairman of the Board is the Chief Executive Officer, our Corporate Governance Guidelines provide that the independent directors shall appoint a lead independent director to serve as the Board sees fit.

The Board currently separates the positions of Chairman of the Board and Chief Executive Officer thereby allowing our Chief Executive Officer to focus on our day-to-day business, while allowing the Chairman of the Board to lead the Board in its fundamental role of providing advice to and independent oversight of management.

The Board recognizes the commitment that our Chief Executive Officer is required to devote to his position, as well as the commitment required for our Chairman of the Board, particularly as the Board's oversight responsibilities continue to grow. Mr. Jacobs and Mr. Mott each are responsible for:

---

Our Chief Executive Officer and Chairman work closely together to execute our strategic plan. Our Chairman leads our Board, serves as a liaison between the Board and senior management team, mentors and advises the senior scientific team, provides an extensive network of contacts, and reports regularly to the Board. We believe the combination of Mr. Jacobs as the President and Chief Executive Officer and Mr. Mott as the Chairman of the Board is an effective leadership structure. The additional avenues of communication between the Board and management associated with having Mr. Mott serve as Chairman provide the basis for the proper functioning of the Board and its oversight of management.

**Board of Directors and Corporate Governance**

Risk assessment and oversight are an integral part of our governance and management processes. One of the most critical roles of our Chief Executive Officer and Board members is managing risk. Today's environment consists of ongoing disruption, innovation, and technological change. Increasing disruption leads to greater risks, which may become greater still because they are often interconnected. Our Chief Executive Officer and senior management team are primarily responsible for managing the risks Novavax faces in the ordinary course of operating the business. The Board actively oversees potential risks and risk management activities by regularly receiving operational and strategic presentations from management, which include discussions of key risks to the business. In addition, the Board delegates risk oversight to each of its key committees within their areas of responsibility.

**Nomination Procedures**

Stockholders who wish to nominate qualified candidates to serve as directors may do so in accordance with the procedures set forth in the Company's By-laws, which procedures did not change during the last fiscal year. As stated in the By-laws, a stockholder must notify the Company in writing, by notice delivered to the attention of the Secretary of the Company at the address of the Company's principal executive offices, of a proposed nominee.

In order to ensure meaningful consideration of such candidates, notice must be received not less than 60 days nor more than 90 days prior to the anniversary date of the applicable year's Annual Meeting of Stockholders. However, in the event the date of the applicable year's Annual Meeting of Stockholders is more than 30 days before or after the anniversary date of the prior year's Annual Meeting of Stockholders, notice by the stockholder to be timely it must be received not later than the close of business on the 10th day following the day on which such notice of the date of the meeting was mailed or public disclosure of the date of such meeting was made, whichever occurs first. In no event shall any adjournment or postponement of a meeting of the stockholders or the announcement thereof commence a new time period for the delivery of the notice described above. Our By-Laws also specify requirements relating to the content of the notice that stockholders must provide in order for a director nomination or other proposal to be properly presented at an Annual Meeting of Stockholders.

Notwithstanding the foregoing, a stockholder who wishes to nominate a candidate to serve as a director must also comply with the requirements of Rule 14a-19 of the Exchange Act.

The Nominating and Corporate Governance Committee strives to maintain a board of directors with a diverse set of skills and qualifications to ensure the board of directors is adequately serving the needs of the Company's stockholders. Before evaluating director candidates, the Nominating and Corporate Governance Committee reviews the skills and qualifications of the directors currently serving on the Board and identifies any skill gaps or skills of particular importance. On the basis of that review, the Nominating and Corporate Governance Committee will evaluate director candidates with those identified skills. The Committee takes into account a broad range of considerations when assessing director candidates, including individual backgrounds and skill

sets, professional experiences, and other factors that contribute to the Board having an appropriate range of expertise, talents, experiences, and viewpoints. The Nominating and Corporate Governance Committee considers the following skills and experiences necessary to the Board: industry knowledge, clinical development expertise, commercialization expertise, manufacturing expertise, financial expertise and capital raising experience, and scientific or medical education and experience, particularly in vaccine-related fields. While there are no set minimum requirements, a candidate should:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• be intelligent, thoughtful, and analytical

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• have excelled in both academic and professional settings

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• possess superior business-related knowledge, skills, and experience

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• demonstrate achievement in his or her chosen field

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reflect the highest integrity, ethics, and character

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• be free of actual or potential conflicts of interest

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• have the ability to devote sufficient time to the business and affairs of the Company

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• demonstrate the capacity and desire to represent the best interests of our stockholders as a whole

In addition to the above criteria (which may be modified from time to time), the Nominating and Corporate Governance Committee may consider such other factors as it deems in the best interests of the Company and its stockholders and that may enhance the effectiveness and responsiveness of the Board and its committees. Finally, the Nominating and Corporate Governance Committee must consider a candidate's independence to make certain the Board includes at least a majority of "independent" directors to satisfy all applicable independence requirements, as well as a candidate's financial sophistication and special competencies.

The Nominating and Corporate Governance Committee identifies potential candidates through referrals and recommendations, including by incumbent directors, management, and stockholders, as well as through business and other organizational networks. The Nominating and Corporate Governance Committee has retained Korn Ferry, a third party consultant, to identify and evaluate, and assist in identifying and evaluating, potential director nominees.

**Board of Directors and Corporate Governance**

The Nominating and Corporate Governance Committee will review and evaluate information available to it regarding candidates recommended by stockholders and will apply the same criteria and follow substantially the same process in considering them as it does in considering other director candidates. Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration by submitting the names of the recommended individuals to Novavax, Inc., 21 Firstfield Road, Gaithersburg, Maryland 20878, Attn: Nominating and Corporate Governance Committee, c/o Corporate Secretary.

Current members of the Board with the requisite skills and experience are considered for re-nomination, balancing the value of the member's continuity of service with that of obtaining a new perspective, and considering each individual's contributions,

performance and level of participation, the current composition of the Board, and the Company's needs. The Nominating and Corporate Governance Committee also must consider the age and length of service of incumbent directors.

If any existing member does not wish to continue in service or if it is decided not to re-nominate a director, any new candidates will be identified in accordance with those skills, experience, and characteristics deemed necessary for new nominees, and are evaluated based on the qualifications set forth above. In every case, the Nominating and Corporate Governance Committee meets (in person or telephonically) to discuss each candidate and may require personal interviews before final approval. Once a slate of nominees is selected, the Nominating and Corporate Governance Committee presents it to the full Board.

**Corporate Governance Guidelines**

The Board has adopted corporate governance guidelines that are available on the Company's website at www.novavax.com.

**Stockholder Communications with the Board of Directors**

The Board welcomes communications from stockholders and has adopted a procedure for receiving and addressing such communications. Stockholders may send written communications to the entire Board or individual directors, addressing them to:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| ![02_NVVX_Email_wBG.jpg](nvax-20260427_g70.jpg) | **MAIL** | Novavax, Inc.<br>Attention: Corporate Secretary<br>21 Firstfield Road<br>Gaithersburg, Maryland 20878 | ![02_NVVX_EmailAdd_wBG.jpg](nvax-20260427_g71.jpg) | **EMAIL** | ir@novavax.com<br>Mark "Attention: Corporate<br>Secretary" in the "Subject" field |

---

All such communication must identify the author as a stockholder and include the stockholder's full name, address, and a telephone number. If the communication is intended for a specific Board member, the name of such Board member should be noted in the communication. The Corporate Secretary, or his designee, will forward any such correspondence to the intended recipient. However, the Corporate Secretary, or his designee, in his or her discretion, may not forward the communication that relates to ordinary business affairs, is clearly of a marketing nature, or is unduly hostile, threatening, illegal, or similarly inappropriate for the Board's consideration.

**Certain Relationships and Related Transactions**

The Company's Audit Committee Charter provides that the Audit Committee is responsible for approving all transactions or business relationships involving Novavax and any director or executive officer, including any transactions between Novavax and either the director or officer personally, members of their immediate families, or entities in which they have an interest. In evaluating related party transactions, the Audit Committee members apply the same standards of good faith and fiduciary duty they apply to their general responsibilities as a committee of the Board and as individual directors. The Audit Committee will approve a related party transaction when, in its good faith judgment, the transaction is in the best interest of the Company.

There are no family relationships among any of the directors or executive officers (or any board member nominee) of Novavax. No director, executive officer, nominee, or any associate of any of the foregoing has any interest, direct or indirect, in any proposal to be considered and acted upon at the Annual Meeting (other than the election of directors).

**Compensation of Directors**

Pursuant to our non-employee director compensation policy, compensation paid to our non-employee directors is comprised of two components: (i) cash compensation and (ii) equity awards. Mr. Jacobs did not receive compensation for his service on the Board during the fiscal year ended December 31, 2025.

The Compensation Committee, working with its independent compensation consultant, conducts annual analyses of our director compensation program and makes recommendations to the Board about the non-employee director compensation program. The Board then approves any changes to the program, as well as the approach to equity compensation for that year. Novavax's annual non-employee director compensation is generally structured to deliver competitive compensation relative to the peer group used for executive compensation setting purposes.

**CASH COMPENSATION**

Our non-employee director cash compensation arrangement for 2025, pursuant to our non-employee director compensation policy, was as follows:

---

| | |
|:---|:---|
| **Non-Employee Director Service** | **Cash Retainer<br>($)** |

---

Our non-employee director compensation policy provides that, by December 31 of each year, a non-employee director may elect to receive Common Stock in lieu of 50% or 100% of his or her annual cash fee for the following year. If a non-employee director elects to receive Common Stock in lieu of his or her annual cash fee, such shares of Common Stock will be granted quarterly in arrears on the last day of each calendar quarter of the applicable year, with (i) the number of shares of Common Stock determined based on the 10-day average closing price of the shares of Common Stock, determined as of the last day of the applicable quarter (i.e., the 10 trading days immediately preceding such last day of the applicable quarter), rounded down to the nearest whole share, and (ii) any fractional share amount paid to the non-employee director in cash. No director made such election for the fiscal year ending December 31, 2025.

Directors do not receive compensation for attending meetings. Directors are reimbursed for reasonable costs and expenses incurred in connection with attending any Board or committee meetings or any other Company related business activities.

**DIRECTOR DEFERRED FEE POLICY**

The Company's Director Deferred Fee Policy for its non-employee directors permits an eligible director to defer receipt of all or part of the director's cash retainer. To defer fees payable during any calendar year, a director must make an election by the end of the preceding calendar year. A director can elect to have 100% of deferred amounts credited to a "cash account" or a "Company common stock account," or, alternatively, a director may elect to have deferred amounts credited 50% to each account. Cash accounts are credited with interest quarterly at the IRS Applicable Federal Rate for short-term debt instruments for the last month of such calendar quarter. Company Common Stock accounts are credited as if amounts were invested in notional stock units based upon the market price of Common Stock and are credited with additional notional units if dividends are paid on Common Stock. Payment of deferred amounts is to be made in cash upon the occurrence of certain events, including the director's separation from service, the death of the director, or a change in control of the Company. The director may also elect to receive payment of the deferred amounts in a specified year that is not more than ten years from the year in which the director's fees were earned. A director may elect to receive payment in either a lump sum or in up to ten annual installments. No director made such election for the fiscal year ending December 31, 2025.

**EQUITY AWARDS**

***Director Equity Compensation***

Historically, we have emphasized equity compensation as a component of our non-employee director compensation program in order to conserve cash and align our directors' interests with those of our stockholders.

On June 20, 2025, after reviewing peer group data provided by Pearl Meyer & Partners, LLC ("Pearl Meyer"), the Compensation Committee's independent compensation consultant, the Board granted awards based on the market data provided.

2025 non-employee annual director equity awards generally targeted delivering value within a competitive range of the 50<sup>th</sup> percentile of the peer group used for executive compensation setting purposes, using data provided by Pearl Meyer to the Compensation Committee. During 2025, directors devoted substantial time to Company matters. The Board held 4 meetings during 2025 and Board committees held an aggregate of 20 meetings.

***Annual Equity Awards***

Under our non-employee director compensation policy, our non-employee directors receive an annual equity award consisting of options and RSUs, with an aggregate grant date fair value of approximately $350,000 (or, for the chairperson of the Board, such other amount as determined by the Board or the Compensation Committee). On June 20, 2025, the Board granted options to purchase 28,330 shares of Common Stock to each of Dr. Douglas Mses. King and McGlynn, and Messrs. Alton, Rodgers and Mott. All of the aforementioned options have an exercise price per share equal to the closing price of a share of Common Stock on the grant date $6.41 and will vest in full one year from the date of grant subject to continued service on the Company's Board through the vesting date.

On June 20, 2025, the Board granted time-vesting RSUs representing a right to receive 18,880 shares of Common Stock to each of Dr. Douglas, Mses. King and McGlynn, and Messrs. Alton, Rodgers and Mott. All of the aforementioned RSUs will vest in full one year from the date of grant subject to continued service on the Company's Board through the vesting date.

***Initial Equity Awards***

Any eligible non-employee director who is elected or appointed to the Board will receive an initial equity grant at 1.5x the value of the annual grant value for non-employee directors, which will be granted on the date of appointment and vest in in three equal annual installments from the date of grant, subject to continued service on the Company's Board through the vesting date. On March 10, 2025, the Board granted Dr. Shiver options to purchase 35,770 shares of Common Stock with an exercise price per share equal to the closing price of a share of Common Stock on the grant date $8.18, On March 10, 2025, the Board granted Dr. Shiver time-vesting RSUs representing a right to receive 23,840 shares of Common Stock. On April 25, 2025, the Board granted Mr. Newton options to purchase 42,840 shares of Common Stock with an exercise price per share equal to the closing price of a share of Common Stock on the grant date $6.67, On April 25, 2025, the Board granted Mr. Newton time-vesting RSUs representing a right to receive 28,560 shares of Common Stock. In connection with his retirement from the Board in March 2025 and in light of his contributions to the Company, the Board determined to accelerate the outstanding unvested equity awards held by Dr. Young as of his retirement date and the post-termination exercise period with respect to his option award was extended through the expiration date of such option award.

**Executive Officers and Compensation**

**EXECUTIVE COMPENSATION PROGRAM**

Our executive compensation program is designed to attract and retain appropriately qualified and industry experienced executives capable of leading the company to the consistent delivery of our mission, vision, and goals. We maintain a compensation philosophy that rewards executives for Company performance tied to attainment of key performance goals.

The Compensation Committee believes the components of our executive compensation program provide the tools needed to deliver appropriate at-risk, variable compensation to retain and reward the executive team, aligned with general industry practices, and that aligns the interests of our executives with those of our stockholders.

***2025 Performance Highlights***<br>

We made significant progress on our corporate strategic transformation in 2025, remaining focused on driving both near and long-term value with our game-changing technology built on a lean and efficient operating model. As the Company is evolving from a global commercial organization with a singular focus on COVID-19 to driving value through partnerships and R&D innovation, we successfully executed against our existing partnerships, made progress towards new potential partnerships, and advanced R&D innovation with our Matrix adjuvant and our organic pipeline.

In 2025, we achieved all $225 million in potential milestones for our Sanofi partnership, with continued strengthening and execution of other partnership agreements including those with Takeda and the Serum Institute of India for R21/Matrix-M malaria vaccine. We made significant progress securing new partners with multiple material transfer agreements (MTAs) signed and the foundation laid for our 2026 agreement with pharmaceutical giant, Pfizer. These agreements all demonstrated the value other companies with vaccine portfolios see in our Matrix adjuvant.

**Executive Officers and Compensation**

In 2025, we continued our focus on leveraging R&D to strengthen our technology platform, expanded our Matrix adjuvant's utility both within and potentially beyond infectious disease in areas like oncology, and drove further proof points and data to develop new assets with which we can partner.

We also continued our progress in stabilizing the Company financially, streamlining our operating expenses to enable value creation. In 2025, we reduced combined R&D and SG&A expenses by 31%, as compared to 2024.

Throughout the year, the Board, along with Mr. Jacobs, sought to build and strengthen the team in order to advance these efforts. The Compensation Committee believes that the 2025 compensation for our Named Executive Officers appropriately reflects the operational progress achieved by Novavax and will motivate the continued achievement of our corporate strategy and anticipated milestones in 2026 and beyond, with the goal of creating value for our stockholders. Our operational results in 2025 included the following highlights:

2025 was a pivotal year, as the Company has evolved from a global commercial organization with a singular focus on COVID-19 to driving value through partnerships and R&D innovation. Through leadership changes, aggressive cost cutting and reducing liabilities, developing partnerships, and driving innovation on our technology platform, management has positioned the Company for long-term growth via a diversified revenue base and on a path to non-GAAP profitability as early as 2028.

**Executive Officers and Compensation**

***Executive Transitions***

Effective June 20, 2025, Mr. Trizzino's employment as President and Chief Operating Officer terminated with us. In connection with his termination, the Company and Mr. Trizzino entered into a consulting agreement pursuant to which Mr. Trizzino provided consulting services to the Company following his termination as President and Chief Operating Officer, until March 31, 2026, and received certain payments and benefits.

In addition, effective March 27, 2026, Dr. Draghia-Akli's employment as Executive Vice President, Research & Development was terminated as an Involuntary Termination without Cause as described on page [56](#i1f3a64f1628f4c4e9d8b954d619c9033_1-0-1-1-59240) below.

**OBJECTIVES OF THE EXECUTIVE COMPENSATION PROGRAM**

The Compensation Committee believes the compensation for our executive officers should be designed to attract, retain, and reward highly qualified executive officers responsible for the success of Novavax and should be determined within a framework that rewards performance and aligns the interests of the executive officers with the interests of the Company's stockholders.

Within this overall philosophy, the Compensation Committee's objectives are to:

---

| | | | | |
|:---|:---|:---|:---|:---|
| ![02_NVAX_CircleNumber_1.jpg](nvax-20260427_g86.jpg) | ![02_NVAX_CircleNumber_2.jpg](nvax-20260427_g87.jpg) | ![02_NVAX_CircleNumber_3.jpg](nvax-20260427_g88.jpg) | ![02_NVAX_CircleNumber_4.jpg](nvax-20260427_g89.jpg) | ![02_NVAX_CircleNumber_5.jpg](nvax-20260427_g90.jpg) |
| Attract and retain appropriately qualified and industry experienced executives | Align executive compensation with competitive market practices | Align executives' interests with those of our stockholders | Reward executives for meeting the strategic goals and objectives of the Company | Reward strong individual performance |

---

***Attract and Retain Appropriately Qualified and Industry Experienced Executives***<br>

Our executive compensation program is designed to attract, motivate, and retain, from a limited pool of available talent, individuals who are appropriately qualified and industry experienced with proven records of success, and to provide total compensation that is competitive with Company peers within the biotechnology and pharmaceutical industries.

***Align Executives' Interests with Those of Our Stockholders***

The Compensation Committee believes that the Company's long-term success depends upon aligning executives' and stockholders' interests. To support this objective, Novavax provides executive officers with the opportunity to receive equity grants in various forms. We consider grants of stock options to align the interests of our executives with our stockholders' interests because value is created in such grants only when the value of Common Stock appreciates after the grant. We also view RSUs granted to our executive officers as important incentives, designed to encourage retention and stock ownership as well as value creation.

We generally grant equity awards on a predetermined annual cadence, and do not have a typical practice of awarding off-cycle, special, or supplemental equity awards.

For a discussion of equity grants made to our NEOs, see "Equity Awards" below.

***Reward Executives for Meeting Strategic Goals and Objectives of the Company***

The Compensation Committee believes a significant portion of an executive officer's total compensation should reflect overall Company performance. The executive compensation program rewards the Company's executive officers for achieving specified corporate performance goals, as well as goals that fall within their individual functional areas. Incentives are based on meeting criteria in each of these categories and reflect the executive officer's overall contribution to the Company's performance. The Compensation Committee also believes that it is appropriate to partially reward our executive officers for their contributions to important corporate performance goals that are partially, but not fully, achieved.

**Executive Officers and Compensation**

***Reward Strong Individual Performance***

As described under "Incentive Cash Bonus Program" below, the Compensation Committee assessed individual performance for each of Mr. Kelly, Ms. O'Hara, Mr. Casey, and Dr. Draghia-Akli and determined that such individual performance was achieved at a level of 120%, 117%, 110%, and 100% of target, respectively. Each executive's bonus payout was different in 2025, which reflects each executive's individual performance and contributions and areas of oversight.

Mr. Jacobs' 2025 annual bonus was based 100% on achievement of the 2025 Objectives, as described below.

In addition, as a result of his termination of employment, Mr. Trizzino was not eligible to receive a 2025 annual bonus.

**OVERSIGHT AND OPERATION OF THE EXECUTIVE COMPENSATION PROGRAM**

The Compensation Committee is appointed by the Board to assist in the development, review, and approval of the compensation of the Company's directors and executive officers, as well as the development of the Company's compensation plans. For details on the Compensation Committee's oversight of the executive compensation program and details of the Committee's charter, see the section titled "Information Regarding the Board and Corporate Governance Matters — Compensation Committee" beginning on page [14](#i79c18862af5c43c1a67d638f571250a0_52) of this Proxy Statement.

The CEO evaluates and provides to the Compensation Committee performance assessments and compensation recommendations for each executive officer other than himself. The Board Chairman, in concert with the Compensation Committee, evaluates the CEO's performance and makes compensation recommendations for the CEO to the Compensation Committee. The Compensation Committee considers the CEO's and the Board Chairman's recommendations, information provided by the Human Resources team, and advice provided by its compensation consultant in its deliberations regarding executive compensation and determines the compensation of the executive officers based on such deliberations. In 2025, the CEO and the Executive Vice President, Chief Human Resources Officer generally attended Compensation Committee meetings, but, other than to address specific questions from the Compensation Committee, were not present for executive sessions or any discussion of their own compensation.

***Independent Compensation Consultant***

The Compensation Committee retains an independent compensation consulting firm to assist and advise on executive and Board compensation. As required by rules adopted by the SEC under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the Compensation Committee engaged Pearl Meyer as an independent compensation consultant after assessing Pearl Meyer's independence. Based upon this assessment, it was determined that the engagement of Pearl Meyer did not raise any conflicts of interest or similar concerns. The Compensation Committee assesses Pearl Meyer's independence and potential conflicts of interest on a regular basis and no less than annually.

Our outside compensation consultant is independent, reports directly to the Compensation Committee, and advises on compensation levels and practices. The role of the Compensation Committee's independent compensation advisor includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reviewing executive compensation marketplace trends and best practices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Informing the Compensation Committee of regulatory developments relating to executive compensation practices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Advising the Compensation Committee on peer companies for compensation plan designs and competitive pay levels;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Assessing the competitiveness and appropriateness of compensation plans and pay levels;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Generally advising the Compensation Committee on other relevant matters; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Providing compensation risk assessments.

**Executive Officers and Compensation**

Pearl Meyer is authorized by the Compensation Committee to work with certain executive officers of the Company, as well as other employees in the Company's Human Resources, Legal, and Finance departments in connection with its work on behalf of the Compensation Committee.

**PROCESS FOR SETTING EXECUTIVE COMPENSATION**

Generally, compensation packages for each executive officer are analyzed and discussed separately at the first Compensation Committee meeting each year. Prior to that meeting, the Compensation Committee's independent compensation consultant performs a comprehensive competitive analysis on the compensation package for each executive officer. In the fourth quarter of 2024, Pearl Meyer completed a thorough competitive analysis for 2025 executive compensation, and this analysis was used by the Compensation Committee to inform decisions made regarding base salaries, target incentive cash bonus opportunities, and equity awards granted to our executive officers. The Compensation Committee generally targets the 50<sup>th</sup> percentile of the applicable Market Data for each role, and reserves the right to compensate an individual above or below that level based on relevant factors at that time.

Pearl Meyer followed a similar process in 2025 to assist the Compensation Committee in determining 2026 compensation arrangements for our NEOs.

***Use of Market Data***

When determining overall compensation for 2025, the Compensation Committee reviewed an analysis, provided by Pearl Meyer, based on relevant market data from a combination of life sciences industry compensation survey data and compensation information from an individual set of comparable publicly traded companies (the "Peer Group"), collectively referred to as "Comparative Market Data."

The Compensation Committee selected the companies in the Peer Group with the assistance of Pearl Meyer based on factors including, but not limited to, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• industry sector

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• stage of development

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• market capitalization

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• business focus

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• employee headcount

The Peer Group utilized in 2025 consists of the following 20 companies\*:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp;• ACADIA Pharmaceuticals Inc.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Alkermes plc<br>&nbsp;&nbsp;&nbsp;&nbsp;• Amphastar Pharmaceuticals, Inc. <br>&nbsp;&nbsp;&nbsp;&nbsp;• ANI Pharmaceuticals, Inc.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Arvinas, Inc<br>&nbsp;&nbsp;&nbsp;&nbsp;• Beam Therapeutics Inc.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Bicycle Therapeutics plc | &nbsp;&nbsp;&nbsp;&nbsp;• BioCryst Pharmaceuticals, Inc.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Corcept Therapeutics Incorporated <br>&nbsp;&nbsp;&nbsp;&nbsp;• Crinetics Pharmaceuticals, Inc.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Denali Therapeutics Inc.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Dynavax Technologies Corporation <br>&nbsp;&nbsp;&nbsp;&nbsp;• Emergent BioSolutions Inc. | &nbsp;&nbsp;&nbsp;&nbsp;• Intellia Therapeutics, Inc.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Pacira BioSciences, Inc. <br>&nbsp;&nbsp;&nbsp;&nbsp;• PTC Therapeutics, Inc.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Sana Biotechnology, Inc.<br>&nbsp;&nbsp;&nbsp;&nbsp;• Supernus Pharmaceuticals, Inc. <br>&nbsp;&nbsp;&nbsp;&nbsp;• Ultragenyx Pharmaceutical Inc. <br>&nbsp;&nbsp;&nbsp;&nbsp;• Vir Biotechnology, Inc.  |

---

\*&nbsp;&nbsp;&nbsp;&nbsp;The following companies were removed from the 2024 peer group: Amarin Corporation plc, Amneal Pharmaceuticals Inc., Halozyme Therapeutics, Inc., Insmed Incorporated, Organogenesis Holdings, Inc., and Vanda Pharmaceuticals Inc. due to being outside of our stated size criteria (market cap, revenue, headcount); and Intercept Pharmaceuticals, Inc due to the Company being acquired. The following companies were added to the 2025 peer group: Arvinas, Inc, Beam Therapeutics Inc., Bicycle Therapeutics plc, Crinetics Pharmaceuticals, Inc., Denali Therapeutics Inc., Intellia Therapeutics Inc., and Sana Biotechnology, Inc.

In addition to the Peer Group, Pearl Meyer provided industry and size-appropriate compensation survey data for Named Executive Officer positions where an adequate peer group sample was not available.

**Executive Officers and Compensation**

For 2025, Pearl Meyer benchmarked each executive officer's current total cash compensation against the 50<sup>th</sup> percentile of the Comparative Market Data. The Compensation Committee determined that this benchmarking was appropriate for targeting compensation opportunities, such as target bonus levels, in order to ensure that our programs remain aligned with market practices and position the overall cost of our program reasonably relative to those of our peers. In line with our compensation philosophy of pay-for-performance, actual compensation levels, such as earned bonuses, will reflect the Company's and the individual's performance.

***Internal Factors***

In addition to Comparative Market Data, the Compensation Committee considers various internal factors when evaluating compensation decisions. These factors include, but are not limited to, internal equity, an executive's experience both broadly and in his or her current role, the scope of the role, individual performance, contributions, and how critical the role is to the Company's business objectives and long-term business strategy. These factors help ensure the Company is fair in its compensation practices across roles similar in scope and level of responsibility.

***Say on Pay Vote Results*** <br>

We conducted our most recent advisory vote on executive compensation at our 2025 Annual Meeting of Stockholders. The Board and the Compensation Committee value the opinions of our stockholders. Close attention was given to the outcome of this vote even though it is non-binding. Approximately 72.3% of the votes cast on the advisory vote on executive compensation were in favor of our Named Executive Officer compensation as disclosed in our 2025 proxy statement.

We continued our stockholder outreach in 2025 to seek feedback on our governance and executive compensation practices, and the information we obtained from these engagements is highly valued. We contacted our top stockholders representing approximately 78% of our institutional ownership and 46% of shares outstanding. As part of this outreach we reached out to each of our top 20 institutional stockholders offering conversations with management and members of the Board in an effort to better understand their views specifically on our executive compensation program following the results of the say-on-pay vote on 2024 Named Executive Officer compensation and gather feedback on how to address stockholders' expectations going forward. This engagement effort was supported by Board members including the Chairman of the Compensation Committee, as well as members of management including our Chief Executive Officer, Chief Financial Officer, Chief Legal Officer, and head of Investor Relations.

Through this outreach we sought continued alignment with our stockholders on how to further enhance the design of our executive compensation program to achieve our shared objectives. Stockholder feedback during this year's outreach was largely positive, with investors expressing support for the progress Novavax has made in recent years, including the design of the compensation program and related disclosures given the evolution of the Company strategy. No stockholders during this year's outreach suggested or recommended changes to the structure or elements of our current executive compensation program, and the Committee viewed this as validation of our program design. We will continue to regularly engage with our stockholders on compensation matters and will continue to address issues and suggestions received through these stockholder outreach efforts. Our Board and the Compensation Committee remain committed to ongoing dialogue with our stockholders and incorporating such feedback with the objectives of our compensation philosophy when designing our executive compensation program in 2026.

**WHAT THE COMPENSATION PROGRAM IS DESIGNED TO REWARD**

***Company & Individual Performance***

The executive compensation program is designed to reward both individual and Company performance. Because of the key roles the executive officers play in the success of the Company, a significant portion of the achievement of corporate goals and the Compensation Committee's assessment of overall Company Performance is reflective of the executive officers' individual performance. Accordingly, a significant portion of an executive officer's total compensation package is based on objective measures of the Company's performance and the achievement of designated corporate goals. In 2025, the Company set five corporate objectives ("2025 Objectives"), that are described below under "2025 Performance and Outcomes." In addition, the Compensation Committee also evaluated individual performance for our currently employed Named Executive Officers, other than our CEO, whose incentive compensation was based partially on achievement of the 2025 Objectives and overall Company Performance and the discretion of the Board.

**Executive Officers and Compensation**

**ELEMENTS OF COMPENSATION**

The Compensation Committee believes the most effective executive compensation program is one that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provides a competitive base salary

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• rewards the achievement of established goals and objectives

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provides an incentive for retention

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• aligns compensation with the interest of stockholders

For this reason, the executive compensation program is comprised of three primary elements:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)base salary — the base salary provides recognition of an individual's role, responsibility, and experience

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)an incentive cash bonus program — variable pay designed to reward achievement of objectives and overall business performance

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)equity awards — variable compensation that promotes a culture of ownership and aligns the interests of the executive with those of the stockholders

The Compensation Committee believes these three elements provide an effective way to motivate and retain executive officers. Equity-based compensation is the most significant portion of compensation for our Named Executive Officers.

The Compensation Committee has not adopted any formal guidelines for allocating total compensation between equity compensation and cash compensation, but generally seeks to provide an overall executive compensation package designed to attract and retain appropriately qualified and industry experienced executive officers, align their compensation with competitive market practices, align their interests with the interests of our stockholders, and reward them for meeting the strategic goals and objectives of the Company, as well as strong individual performance.

***Base Salary***

The Compensation Committee's philosophy is to maintain base salaries at a competitive level sufficient to recruit and retain individuals possessing the skills and capabilities necessary to achieve the Company's goals over the long term. The Compensation Committee determined to provide modest annual base salary increases for our Named Executive Officers for 2025. The Compensation Committee considered Comparative Market Data, and the internal factors described above, as well as retention and succession considerations in determining salary increases.

The base salaries for our currently employed NEOs and Dr. Draghia-Akli as of December 31, 2025, were:

---

| | | | |
|:---|:---|:---|:---|
| **Executive**<sup>(1)</sup> | **Base Salary<br>($)** | **Percentage Increase in Base<br>Salary from December 31, 2024** | **Nature of Increase** |
| John C. Jacobs | 797500 | 3.6% | Merit |
| James P. Kelly | 576223 | 3.6% | Merit |
| Elaine O'Hara | 565136 | 4.5% | Merit |
| Mark J. Casey, J.D. | 581196 | 3.6% | Merit |
| Ruxandra Draghia-Akli, M.D., Ph.D.<sup>(2)</sup> | 600000 | —% |  |

---

(1)Mr. Trizzino is not included in this table because his employment terminated effective June 20, 2025. His annual salary at time of departure was $601,778.

(2)Dr. Draghia-Akli was not eligible for an increase in salary because she joined the Company in November 2024.

***Incentive Cash Bonus Program***

The 2025 incentive cash bonus program was designed to motivate and reward executive officers for the achievement of specific corporate objectives and to drive overall Company performance. The purpose of the incentive cash bonus program is to align company, departmental, and individual goals throughout the Company and to provide an incentive that further ties compensation to individual contribution and teamwork.

A target bonus for each Named Executive Officer is set as a percentage of the executive officer's base salary, with such percentages based on market data, although the ultimate amount of any bonus payout is at the discretion of the Compensation Committee and based on the level of achievement of applicable bonus plan objectives and an assessment of overall Company performance, as well as individual performance. We did not make any increases to the target bonus opportunities for our Named Executive Officers in 2025 from 2024.

In the first quarter of 2025, the Compensation Committee set and approved the performance objectives for the 2025 incentive cash bonus program (the "2025 Objectives"). In setting the 2025 Objectives, the Committee considered the evolution of the Company's business strategy from a global commercial organization with a singular focus on COVID-19 to driving value through partnerships and R&D innovation. The objectives reflect the Company's ongoing strategic transformation in 2025 and are intended to promote future value creation for shareholders, with focus on optimizing future cash flow through partnerships and royalties, creating long-term stability through operational expense reduction, and advancing our early-stage pipeline. Under our partnership agreement with Sanofi, they became responsible for commercialization of Nuvaxovid in 2025.

We replaced the commercial objective from 2024 with two objectives: advancing our Sanofi partnership and closing additional business development deals. Each of these objectives was given a weight of 30%, reflecting the importance of generating milestone payments and future royalties to creating long-term value for shareholders. A continued focus on advancing our technology platform and early-stage pipeline remained important in 2025 for long-term growth opportunities. Additionally, the objectives reflect our continued focus on refining our organization, cost, and capital structure critical for long-term stability, as well as evolving our company capabilities and culture in support of the ongoing business transformation.

**Executive Officers and Compensation**

As described above, for 2025, the Board set five 2025 Objectives: advance Sanofi partnership (30%), close additional business development deals (30%), generate data to advance value of technology platform and pipeline (15%), refine organization, cost, and capital structure (20%) and evolve company capabilities and culture (5%). The maximum cash bonus amount for fiscal 2025 was capped at achievement of 150% of target, which the Company considered appropriate to minimize excessive risk taking while still aligning pay-for-performance.

In December 2025, the Compensation Committee reviewed the Company's performance related to the 2025 Objectives. As described above under "2025 Performance and Outcomes," the overall achievement of the 2025 Objectives was 93%. In addition to its assessment of corporate performance against the pre-established 2025 Objectives, the Compensation Committee also considered the overall Company performance in 2025 in the context of unforeseen challenges during a pivotal and transformational year and management's ability to substantially deliver on all objectives and navigate in an unprecedented environment, and as a result, modestly increased the level of the 2025 corporate achievement to 95%. The Compensation Committee considered the magnitude of this adjustment and its effect on total payouts under the 2025 incentive cash bonus program and determined that the adjustments were appropriate in size and did not result in a disproportionate increase in the overall achievement percentage.

For each of our NEOs who were employed as of December 31, 2025 (except for Mr. Jacobs, whose 2025 annual bonus was based 100% on achievement of the 2025 Objectives and overall Company performance as outlined above), the Compensation Committee reviewed the assessment and recommendation provided by Mr. Jacobs, for each such NEO's individual contribution to company performance as outlined below:

Based on the CEO's assessment of, and the Compensation Committee's review of, individual performance, the Compensation Committee determined that each of Mr. Kelly, Mr. Casey, Ms. O'Hara, and Dr. Draghia-Akli achieved his/her applicable individual performance metrics at 120%, 110%, 117%, and 100%, respectively, of target. The actual bonus paid to each executive, other than the CEO, was determined by multiplying the overall company achievement factor of 95% by 65% of the target bonus value and multiplying the individual achievement factor for each executive multiplied by 35% of the target bonus value.

(1)Mr. Trizzino is not included in this table because his employment terminated effective June 20, 2025, and therefore was not eligible for a 2025 bonus.

(2)The 2025 bonus payouts for all NEOs were determined on a prorated basis to account for the increases in base salaries during the year.

(3)Based on the CEO's assessment of, and the Compensation Committee's review of, individual performance, the Compensation Committee determined that each of Mr. Kelly, Mr. Casey, Ms. O'Hara, and Dr. Draghia-Akli achieved his/her applicable individual performance metrics at 120%, 110%, 117%, and 100%, respectively, of target.

***Equity Awards***<br>

Equity awards are a fundamental incentive component in the Company's executive compensation program because they emphasize long-term performance, as measured by creation of stockholder value, and foster a commonality of interest between stockholders and executives. In addition, they are crucial to a competitive compensation program for executive officers because they act as a powerful retention tool. The Compensation Committee believes that equity awards create appropriate incentives for rewarding our executives for increases in stock performance as a result of our efforts towards improved global health and align the executives' interests with those of our stockholders. We generally grant equity awards on pre-determined annual cadence and do not have a typical practice of awarding off-cycle, special, or supplemental equity awards.

The Compensation Committee reviews the structure and design of our equity awards each year as part of the compensation planning process. The Company has historically granted an equity mix comprised of both stock options and RSUs to executive officers. For 2025, the Compensation Committee considered implementing performance-based equity awards as part of our equity mix, but ultimately determined that this equity vehicle was not suitable at this time in light of our ongoing strategic transformation. In addition, the Committee's independent Compensation Consultant, Pearl Meyer, confirmed that the use of a mix of stock options and RSUs is the most common approach in the peer group, and that granting performance-based equity is a minority practice. In evaluating the use of the different equity award instruments, the Committee carefully considered these competitive market findings and the objective to structure a compensation program that reflects the competitive market. For 2025, the Committee determined that each executive would receive 50% of their annual award in stock options and 50% of their annual award in RSUs.

In the case of stock options, the recipients are motivated by the potential appreciation in stock price above the exercise price at which they are granted. RSUs encourage continued employment as these awards require the executive to remain in continued service with the Company for three years before the award is fully vested. The Compensation Committee believes it is important to tie the long-term benefit potentially realizable by the executive to a long-term commitment with Novavax.

Annual equity grants are awarded to executive officers at the discretion of the Board upon a recommendation by the Compensation Committee or at the discretion of the Compensation Committee pursuant to the authority delegated to it by the Board. In making its recommendations or determinations, the Compensation Committee considers Company performance, market data provided to the Compensation Committee by Pearl Meyer, and the individual's scope of responsibility and performance. After reviewing guidance from Pearl Meyer based on its analysis of competitive data, annual equity awards were awarded to eligible employees, including Mr. Jacobs, Mr. Kelly, Mr. Casey, Ms. O'Hara and Dr. Draghia-Akli in March 2025.

***Annual Stock Option Awards***

In March 2025, the Compensation Committee awarded options to purchase shares of Common Stock to each of Mr. Jacobs, Mr. Kelly, Mr. Casey, Ms. O'Hara, and Dr. Draghia-Akli. Each stock option vests as to 25% of the shares underlying the option on the first anniversary of the grant date and as to the remaining 75% of the shares in equal monthly installments over a three-year period, generally subject to continued service with the Company through the applicable vesting date. The following table sets forth the number of shares underlying the time-vesting stock options granted to the NEOs in 2025:

---

| | |
|:---|:---|
| **Executive** | **Time-Vesting<br>Stock Options** |
| John C. Jacobs | 676,000 |
| James P. Kelly | 194,500 |
| Elaine O'Hara | 253,500 |
| Mark J. Casey, J.D. | 169,000 |
| Ruxandra Draghia-Akli, M.D., Ph.D. | 120,000 |

***Annual Restricted Stock Unit Awards***

In March 2025, the Compensation Committee awarded time-vesting RSUs to each of Mr. Jacobs, Mr. Kelly, Ms. O'Hara, Mr. Casey, and Dr. Draghia-Akli. Such time-vested RSUs vest in three equal annual installments on the first three anniversaries of the date of grant, in each case generally subject to continued service with the Company through the applicable vesting date. The following table sets forth the RSUs granted to each of the NEOs.

---

| | |
|:---|:---|
| **Executive** | **Time-Vesting<br>Restricted Stock Units** |
| John C. Jacobs | 450,500 |
| James P. Kelly | 129,500 |
| Elaine O'Hara | 169,000 |
| Mark J. Casey, J.D. | 112,500 |
| Ruxandra Draghia-Akli, M.D., Ph.D. | 80,000 |

***Clawback Policy***

In June 2023, we adopted our Second Amended and Restated Recoupment Policy (the "Clawback Policy") in compliance with the requirements of the Dodd-Frank Act, final SEC rules and applicable Nasdaq listing standards, which covers our current and former executive officers. If the Company is required to prepare an accounting restatement due to material errors or non-compliance with financial reporting requirements under applicable securities laws, covered incentive-based compensation paid or awarded to covered executives will be subject to reduction and/or repayment if the amount of such compensation was calculated based on the achievement of financial results that were the subject of the restatement and the amount of such compensation that would have been received by the covered executives had the financial results been properly reported would have been lower than the amount actually awarded.

**Executive Officers and Compensation**

***Stock Ownership Guidelines***

In June 2021, the Board adopted the Stock Ownership Guidelines for our executive team and Board. The Stock Ownership Guidelines require that by the fifth anniversary of the guideline's effective date (i.e., June 17, 2026) or the fifth anniversary of an individual becoming subject to the guidelines (whichever is later), that individual is required to hold a number of shares of Common Stock equivalent in value to a multiple of the individual's salary or, in the case of directors, their annual cash retainer, as follows:

---

| | | |
|:---|:---|:---|
| **CEO** | **Executive Vice President and above** | **Non-Employee Directors** |
| ![04_NVAX_Stock Ownership_CEO.jpg](nvax-20260427_g96.jpg) | ![04_NVAX_Stock Ownership_EVP.jpg](nvax-20260427_g97.jpg) | ![04_NVAX_Stock Ownership_NED.jpg](nvax-20260427_g98.jpg) |

---

The Stock Ownership Guidelines provide that the following shares or share equivalents count towards satisfaction of the guidelines:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• shares owned outright by the executive or director or a member of his or her immediate family residing in the same household,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• shares held in trust for the benefit of the executive or director or a member of his or her immediate family residing in the same household,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• shares or share equivalents held in any Company employee stock purchase plan or deferred compensation retirement plan, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• unvested restricted stock units.

Other unvested equity awards, vested and unexercised stock options, and unearned performance-based equity awards do not count toward satisfaction of the guidelines.

Until the required ownership level is reached, covered executives and non-employee directors are required to retain at least 50% of the shares, net of applicable tax withholding and the payment of any exercise or purchase price (if applicable), received upon the vesting or settlement of equity awards or the exercise of stock options or stock appreciation rights. Once the requisite level has been achieved, ownership of the guideline amount must be maintained for as long as the individual is subject to the Stock Ownership Guidelines.

As of December 31, 2025, all of the covered executives and non-employee directors were in compliance with, or within the five-year grace period under, the Stock Ownership Guidelines.

**EQUITY GRANT POLICIES AND PROCEDURES** 

Our practice is to grant stock options and similar awards in the ordinary course of business in connection with our annual compensation program, hiring new employees, and the retention of employees from time to time. Although we do not have a formal policy with respect to the timing of our equity award grants, we typically grant annual stock options to employees including executive officers at our regularly scheduled first quarter Compensation Committee meeting with the grant date to be effective each March after the public release of earnings for the previous fiscal year. Stock options are granted with an exercise price equal to the closing price of our common stock on the grant date.

We grant annual equity awards to non-employee directors on the date of the annual meeting of stockholders in accordance with our Non-Employee Director Compensation Policy. We do not time the granting of equity awards with any favorable or unfavorable news released by the Company. We do not take material nonpublic information into account when determining the timing and terms of equity awards or for the purpose of affecting the value of executive compensation. Proximity of any awards to an earnings announcement or other market events is coincidental. In the event material nonpublic information were to become known to the Compensation Committee before the grant of an equity award, the Compensation Committee would consider the information and use its business judgment to determine whether to delay the grant to avoid any appearance of impropriety.

All of the NEOs are eligible to participate in the Company's benefit plans offered to all employees during their employment, including health, dental, and vision insurance, a prescription drug plan, flexible spending accounts, short- and long-term disability, life insurance, and a 401(k) plan. The NEOs were also eligible to participate in the ESPP during their employment.

**EMPLOYMENT AGREEMENTS AND SEVERANCE BENEFITS**

As of December 31, 2025, the Company had employment agreements in place with all of the currently employed NEOs and Dr. Draghia-Akli. The employment agreements provide for certain payments if the NEO is terminated by the Company without cause or leaves for good reason. The terms of these agreements are described in greater detail in the section titled "Overview of Employment and Change in Control Agreements." All of the NEOs were "at will" employees during their employment with us.

The Company has established an Amended and Restated Change in Control Severance Benefit Plan (the "Severance Plan"), which provides for severance payments to participating employees if the participant's employment is terminated in connection with a change in control. This plan is described in greater detail in the section titled "Overview of Employment and Change in Control Agreements." The Compensation Committee believes it is important to provide such employees with an incentive to remain with the Company amid the uncertainty that often accompanies efforts to consummate a corporate sale or similar transaction that may enhance stockholder value. All of the currently employed NEOs participate in the Severance Plan.

**TAX AND ACCOUNTING IMPLICATIONS**

Section 162(m) generally limits to $1 million the amount a company may deduct for compensation paid to certain current and former executive officers. The Compensation Committee believes its primary responsibility is to provide a compensation program that attracts, retains, and rewards the executives necessary for our success. Accordingly, the Compensation Committee has authorized, and will continue to authorize, compensation arrangements that are not deductible in whole or in part. The Compensation Committee may consider the accounting implications of significant equity-related compensation decisions.

**INSIDER TRADING POLICY** 

Our Board has adopted an Insider Trading Policy governing the purchase, sale, and other dispositions of the Company's securities that applies to all Company personnel, including directors, officers, employees, and consultants, and other covered persons, which the Company believes is reasonably designed to promote compliance with insider trading laws, rules and regulations and listing standards applicable to the Company. A copy of our Insider Trading Policy was filed as Exhibit 19 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, filed with the SEC on February 26, 2026.

**PROHIBITION ON HEDGING AND PLEDGING**

Our Insider Trading Policy prohibits all directors, officers, and other employees from engaging in short sales or publicly traded options of Company securities (such as puts, calls, and other derivative securities), as well as engaging in hedging of Company securities or similar transactions that transfer to another, in whole or in part, any of the economic consequences of ownership of Company securities. Further, our insider trading policy provides that no director, executive officer, or vice president may engage in any transaction involving pledging of Company securities or holding Company securities in a margin account.

**COMPENSATION RISK ASSESSMENT**

The Compensation Committee regularly reviews the Company's compensation and benefits programs, policies and practices, including its executive compensation program and its incentive-based compensation programs for its executive officers, to determine whether such programs, policies and practices create risks that are reasonably likely to have a material adverse effect on the Company. Our compensation and governance-related policies are enhanced by our clawback policy, described in the section titled "Elements of Compensation — Clawback Policy" on page [45](#i79c18862af5c43c1a67d638f571250a0_172) of this Proxy Statement, as well as a policy prohibiting hedging and pledging of our securities by our directors and officers, including our NEOs and employees, as described above. At the Compensation Committee's direction, on an annual basis the Compensation Committee's independent compensation consultant conducts a risk assessment of our compensation programs. The Compensation Committee and its independent compensation consultant reviewed and discussed the assessment, and the Compensation Committee concurred with the assessment that our compensation programs do not create risks that are reasonably likely to have a material adverse effect on our business.

(1)The target cash bonus amount for fiscal 2025 was based on achievement of 100% of the 2025 Objectives (and, if applicable, 100% of individual performance objectives) and the individual's earned base salary for 2025 and represented 85% of Mr. Jacobs' base salary, and 50% of each of Messrs. Kelly's, and Casey's, Ms. O'Hara's, and Dr. Draghia-Akli's base salary. The maximum cash bonus amount for fiscal 2025 was capped at achievement of 150% of target. The target and maximum amounts reported in the table account for the increase to NEO's base salary during the year. Mr. Trizzino was not eligible for a cash bonus due to his termination effective June 20, 2025.

(2)Represents time-vesting RSUs granted under the 2015 Stock Plan that vest in three equal annual installments on the first three anniversaries of the grant date. In each case, vesting is generally subject to the NEO's continued service with the Company through the applicable vesting date.

(3)Represents time-vesting stock options granted under the 2015 Stock Plan. These stock options have a ten-year term and vest as to 25% of the shares underlying the option on the first anniversary of the grant date and as to the remaining 75% of the shares in equal monthly installments thereafter over a three-year period, in each case generally subject to the NEO's continued service with the Company through the applicable vesting date.

(4)The stock options granted to the NEOs have an exercise price equal to the closing price of a share of Common Stock as reported on Nasdaq on the date of grant (or, if no closing price is reported on that date, the closing price on the immediately preceding date on which a closing price was reported).

(5)With respect to stock options and RSUs granted to each of our NEOs reflects the grant date fair value of each RSU and option award, calculated in accordance with FASB ASC Topic 718. Assumptions used in the calculation of this amount for options are included in Note 14 to the Company's Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 26, 2026. The grant date fair value of the RSU awards was determined by multiplying the number of RSUs subject to the award by the closing price of a share of Common Stock on the date of grant (or, if no closing price was reported on that date, the closing price on the immediately preceding date on which a closing price was reported).

(1)All stock options and SARs included in this table were awarded under the Amended and Restated 2015 Stock Plan, or the Inducement Plan and, except as noted, vest as to 25% on the first anniversary of the grant date, and as to the remaining 75% in equal monthly installments over the following three years, generally subject to continued service with the Company through the applicable vesting date.

(2)All RSUs included in this table were awarded under the 2015 Stock Plan, or the Inducement Plan and, except as noted, vest in three equal annual installments on the first three anniversaries of the date of grant, generally subject to continued service with the Company through the applicable vesting date.

(3)The exercise price of stock options and base value of SARs is equal to the closing price of a share of Common Stock on the date of grant (or, if no closing price is reported on that date, the closing price on the immediately preceding date on which a closing price was reported).

(4)Amounts in this column have been calculated by multiplying the number of RSUs subject to the applicable award by $6.72 which was the closing price of the Common Stock on December 31, 2025, the last trading day in 2025.

(5)Represents performance- and time-vesting stock options that vest subject to the satisfaction of a performance-based vesting requirement, followed by time-based vesting. The performance metric required that the Company initiate a COVID-19 Phase 2 clinical trial within 12 months of the grant date, which occurred when the Company initiated its Phase 2 clinical trial of NVX-CoV2373 in the U.S. on August 24, 2020. As a result of the attainment of the performance objective, these options vested as to 50% of the underlying shares on August 24, 2021 and as to 50% of the underlying shares on August 24, 2022.

**OPTIONS EXERCISED AND STOCK VESTED**

**Executive Officers and Compensation**

**OVERVIEW OF EMPLOYMENT AND CHANGE IN CONTROL AGREEMENTS**

***Employment Agreements; Separation and Consulting Agreements***<br>

The Company has employment agreements in place with each of our currently employed NEOs. The terms "cause" and "good reason" referred to below are defined in the respective NEO's employment agreement.

Each employment agreement provides for a base salary subject to review each year (but, in the case of Mr. Jacobs, not subject to reduction, other than an across-the-board reduction not in excess of 10% of Mr. Jacobs' annual base salary, applicable to all similarly situated executives of the Company) and the eligibility to receive an incentive bonus and equity awards. Salary information and the target amount of the incentive bonus are described in greater detail beginning on page [40](#i79c18862af5c43c1a67d638f571250a0_145) in the CD&A. The amount of any incentive bonus and the form of payment (cash, equity, or some combination of the two) are at the discretion of the Board or the Compensation Committee.

The employment agreement with each NEO requires the NEO to maintain the confidentiality of the Company's proprietary information and provides that all work product discovered or developed by the NEO in the course of the NEO's employment belongs to the Company. In addition, in the employment agreements, the NEOs have agreed not to compete with the Company, directly or indirectly, within the United States or interfere with or solicit the Company's contractual relationships, in each case during the term of his or her employment and for the duration of the 12-month period (or 18 months for Mr. Jacobs) following the termination of his or her employment.

If a currently employed NEO's employment is terminated without "cause" or the NEO leaves the Company for "good reason", the NEO may receive a lump sum separation payment pursuant to the employment agreements. The amount of these payments is more specifically described in the section "Potential Payments Upon Termination or Change in Control" beginning on page [58](#i79c18862af5c43c1a67d638f571250a0_220). To be entitled to such a payment, the NEO must execute and deliver to the Company a waiver and separation agreement, releasing the Company from any claims.

Mr. Jacobs' employment agreement provides that during his employment, the Company will pay or reimburse him for housing and commuting expenses in an amount not to exceed $100,000 per year. Mr. Casey's employment agreement provides that during his employment, the Company will pay or reimburse him for housing and commuting expenses in an amount not to exceed $6,000 per month, plus an additional sum to reimburse him for personal income taxes associated with his commuting allowance. Ms. O'Hara's employment agreement provides that during her employment, the Company will pay or reimburse her for housing and commuting expenses in an amount not to exceed $5,000 per month, plus an additional sum to reimburse her for personal income taxes associated with her commuting allowance. Dr. Draghia-Akli's employment agreement provides that during her employment, the Company will pay or reimburse her for housing and commuting expenses in an amount not to exceed $6,000 per month, plus an additional sum to reimburse her for personal income taxes associated with her commuting allowance.

In connection with the termination of his employment, the Company and Mr. Trizzino also entered into a consulting agreement (the "Trizzino Consulting Agreement") pursuant to which Mr. Trizzino provided consulting services to the Company commencing on June 20, 2025 until March 31, 2026 (subject to earlier termination, the "consulting period"). The Trizzino Consulting Agreement provided that the Company would pay Mr. Trizzino a consulting fee of $15,000 per month and provided that the equity awards previously granted to Mr. Trizzino would continue to vest, subject to his continued service during the consulting period, in accordance with their existing terms, and any stock options that remained outstanding and unexercised as of the last day of the consulting period will remain exercisable for a period of 90 days following the end of the consulting period. Upon termination of the Trizzino Consulting Agreement, any unvested portion of the non-statutory stock options granted pursuant to the March 7, 2023 option award immediately vested as of the termination date. All other provisions of the Non-Statutory Stock Option Agreement remained unchanged.

Additionally, pursuant to Mr. Trizzino's employment agreement, upon Mr. Trizzino's termination of employment without "cause" and execution of a waiver and separation agreement, releasing the Company from any claims, Mr. Trizzino received a lump sum separation payment equal to $601,778 (equal to twelve (12) months of his base salary at the time of termination). Additionally, Mr. Trizzino was eligible for a Cobra Subsidy equal to 12 months of health insurance premiums (medical, dental, vision, and EAP premiums plus 2%) with a total value of $37,413.

**Executive Officers and Compensation**

In connection with the termination of her employment without "cause", the Company and Dr. Draghia-Akli entered into a general release of claims and separation agreement (the "Draghia-Akli Separation Agreement"). Pursuant to the Draghia-Akli Separation Agreement, consistent with the terms of her employment agreement and in consideration of Dr. Draghia-Akli's execution and non-revocation of a general release of claims and her compliance with the applicable restrictive covenants, the Company paid Dr. Draghia-Akli separation pay of a gross amount of $609,000 (equal to twelve (12) months of her base salary at the time of termination) less applicable withholdings and deductions and, subject to Dr. Draghia-Akli timely electing COBRA coverage, the Company would also pay the amount of Dr. Draghia-Akli's full COBRA premiums for up to 12 months (or, if earlier, Dr. Draghia-Akli becomes eligible for health insurance coverage through a new employer, or ceases to be eligible for COBRA during the 12 month period).

***Amended and Restated Change in Control Severance Benefit Plan***

In 2021, the Board adopted the Severance Plan. The purpose of the Severance Plan is to provide severance pay and benefits to employees of the Company at the level of Executive Vice President and above in the event their employment with the Company is terminated following a change in control event, to provide such employees with an incentive to remain with the Company, and help the Company consummate a strategic corporate sale or transaction that maximizes stockholder value. Each of our currently employed NEOs participates in the Severance Plan and, prior to their termination, Mr. Trizzino and Dr. Draghia-Akli were also eligible to participate in the Severance Plan. This section summarizes the terms of the Severance Plan for each of our eligible NEOs.

The Severance Plan provides for the payment of benefits upon certain triggering events. A triggering event occurs if a participant's employment is terminated due to an "Involuntary Termination without Cause" for a reason other than cause death or disability or as a result of a "Constructive Termination" either (i) within a certain protected period set forth in the table below (not to exceed 24 months) after the effective date of a "Change in Control" or (ii) within the one-year period prior to the Change in Control but after the first day on which the Board and/or senior management of the Company has entered into formal negotiations with a potential acquirer that results in the consummation of the Change in Control.

The specific periods of time following the effective date of a Change in Control during which payment of benefits under the Severance Plan may be triggered by termination, and the severance payment and benefits provided pursuant to the Severance Plan, are as follows:

---

| | | | |
|:---|:---|:---|:---|
| | | **Severance**<sup>(1)(2)</sup> | |
|<br>**Executive** | **Protected Period** | **Severance<br>Payment** | **Continuation of <br>Benefits Period** |
| John C. Jacobs | 24 months | 24 months salary | 18 months |
| James P. Kelly | 12 months | 12 months salary | 12 months |
| Elaine O'Hara | 12 months | 12 months salary | 12 months |
| Mark J. Casey, J.D. | 12 months | 12 months salary | 12 months |
| Ruxandra Draghia-Akli, M.D., Ph.D. | 12 months | 12 months salary | 12 months |

---

(1)If a triggering event occurs, the participant is entitled to a lump sum severance payment; a bonus equal to 100% of the target annual performance bonus for the year in which the termination date occurred multiplied by the length in years of the participant's severance benefit period; and an amount equal to the product of 1.02 multiplied by 12 (or 18 for Mr. Jacobs) multiplied by the monthly premium for the cost of insuring the NEO and the NEO's eligible dependents under the company's group health plans in which the NEO participated immediately prior to the date of such termination (the "COBRA Subsidy").

(2)The NEOs are also entitled to certain payments and benefits upon termination of employment that are provided on a non-discriminatory basis to salaried employees generally upon termination of employment. These include accrued salary and accrued but unused vacation pay, and availability for distribution of plan balances under the Company's 401(k) plan.

In addition, all time-based equity or equity-based awards held by the participant will vest in full upon the triggering event and all performance-based equity or equity-based awards will become vested as to the number of shares that would have vested based on the greater of (A) assumed achievement of the applicable performance goals at the target level of performance and (B) actual achievement of the applicable performance goals through the date of the Change in Control, in either case determined as if any applicable service-based vesting requirement had been met. In addition, all vested awards will remain exercisable, as applicable, for a specified period (24 months for Mr. Jacobs and 12 months for Messrs. Kelly and Casey, Ms. O'Hara, and Dr. Draghia-Akli) or for the original term of the award, if shorter.

(1)On December 31, 2025, the Company had employment agreements with Messrs. Jacobs, Kelly, and Casey, Ms. O'Hara, and Dr. Draghia-Akli which provided for a lump sum cash severance payment if the executive's employment was terminated without "cause" or the executive resigned for "good reason" equal to 18 months' base salary for Mr. Jacobs and 12 months' base salary for Messrs. Kelly and Casey, Ms. O'Hara, and Dr. Draghia-Akli. In addition, each of Messrs. Kelly and Casey, Ms. O'Hara, and Dr. Draghia-Akli was also entitled to a payment of a specified number of months of the COBRA Subsidy (18 months for Mr. Jacobs and 12 months for Messrs. Kelly and Casey, Ms. O'Hara, and Dr. Draghia-Akli). Mr. Jacobs was further entitled to the full accelerated vesting of the unvested portion of his stock option grant and RSU grant made by the Company on January 23, 2023, and is entitled to exercise all such outstanding vested stock options held at termination (including any accelerated options or grants) during the 90-day period following the date of termination.

(2)In the event an NEO's employment or service is terminated for cause or the NEO resigns without good reason, the Company has no further obligation to the NEO other than the obligation to pay any unpaid base salary and unused vacation accrued through the termination date.

(3)In the event an NEO's employment or service is terminated as a result of Death or Disability, the Company has no further obligation to the NEO other than the obligation to pay any unpaid base salary and unused vacation accrued through the termination date, as well as the equity acceleration set forth above.

(4)On December 31, 2025, each of our NEOs (other than Mr. Trizzino) was eligible to participate in the Severance Plan, which provides for payments and benefits upon an executive's qualifying termination during the protected period, as described in more detail above under "Amended and Restated Change in Control Severance Benefit Plan." Under the Severance Plan, all time-based equity or equity-based awards held by the participant will vest in full upon the triggering event and all performance-based equity or equity-based awards will become vested as to the number of shares that would have vested based on the greater of (A) assumed achievement of the applicable performance goals at the target level of performance and (B) actual achievement of the applicable performance goals through the date of the Change in Control, in either case determined as if any applicable service-based vesting requirement had been met.

(5)Bonus equals 100% of the NEO's target annual bonus award for 2025, expressed as a monthly payment, multiplied by the participant's severance benefit period, expressed monthly (24 months for Mr. Jacobs and 12 months for each of Messrs. Kelly and Casey, Ms. O'Hara, and Dr. Draghia-Akli).

(6)Column (3) amounts represent the value of all unvested equity awards outstanding at the closing price on December 31, 2025, the last trading day in 2025, $6.72, minus any applicable exercise price.

(7)Reflects the premiums for medical, dental, vision and EAP coverage under the Company's group health insurance program. Amounts are based on the premiums in effect at December 31, 2025.

***Termination as a Result of Death or Disability***

In the event an NEO's employment or service is terminated as a result of death or disability, all outstanding equity awards granted to the NEO on or after March 2016 will vest as to 50% of the unvested portion of each grant as of the termination date. Otherwise, the Company has no further obligation to the NEO other than the obligation to pay any unpaid base salary and unused vacation accrued through the termination date. If the NEO dies while he is a service provider to the Company (or within three months after the date on which the NEO ceases to be a service provider), vested and exercisable options may be exercised by the NEO's estate for one year following the NEO's death (or until the end of the original term of the option, if earlier). If the NEO becomes disabled while he is a service provider to the Company, vested and exercisable options may be exercised by the NEO for a period of one year after the NEO ceases to be a service provider due to a disability (or until the end of the original term of the option, if earlier).

**Executive Officers and Compensation**

**2025 CEO Pay Ratio**

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, the following information describes the relationship of the annual and quarterly total compensation of our employees and the annual total compensation of John C. Jacobs, our President and Chief Executive Officer, who was serving as our Chief Executive Officer as of the determination date.

For 2025:

---

| | | |
|:---|:---|:---|
| | **2025 Annual Total<br>Compensation<br>($)** | **Pay Ratio Estimate<br>(Approximately)** |
| Mr. Jacobs (our President and Chief Executive Officer) | 8856015 |  |
| The median of all employees, other than Mr. Jacobs | 169449 |  |
|  |  | **52:1** |

---

To identify its median employee and determine the annual total compensation of that median employee and the CEO:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company determined that, as of December 31, 2025, its employee population consisted of approximately 751 individuals, with approximately 587 employees based in the United States, 148 employees located in Sweden, 15 employees located in the Czech Republic, and 1 employee located in Switzerland. All employees are included, whether employed as full-time, part-time, temporary, or seasonal employees, and base compensation was annualized for any full-time employee that was not employed for all of fiscal year 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We identified our median employee by reviewing data reflected in compensation records consisting of base salary and annual cash incentive payments, which were consistently applied to all employees included in the calculation. Base salary and annual cash incentive payments were used because they represent the Company's principal broad-based compensation elements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• No cost-of-living adjustments were made in identifying the median employee. For compensation of employees located in Sweden, Czech Republic, and Switzerland, the exchange rate used was the same as for financial statement translation purposes at December 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• All of the elements of such employee's compensation for 2025 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, were totaled, resulting in annual total compensation of $169,449.

The CEO Pay Ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules, based on our internal records, and the methodology described above. The SEC rules for identifying the median compensated employee allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the CEO Pay Ratio reported above, as other companies have different employee populations and compensation practices and may use different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

(a)Compensation Actually Paid excludes the amounts reported in the Stock Awards and Option Awards columns from the relevant fiscal year's Summary Compensation Table.

For the values of equity awards included in the above table, fair values are calculated in accordance with FASB ASC Topic 718. which, in the case of performance-based awards, are based on the probable outcome of the performance conditions as of the applicable measuring date or actual performance results approved by the Compensation Committee as of the applicable vesting date. Otherwise, the valuation assumptions used to calculate fair values did not materially differ from those used in our disclosures of fair value as of the grant.

(6)Represents the cumulative total return on $100 invested in the Company's Common Stock as of the last day of public trading of the Company's Common Stock in fiscal year 2020 through the last day of public trading of the Company's Common Stock in the applicable fiscal year for which the cumulative total return is reported. The Company did not pay dividends for any of 2025, 2024, 2023, 2022, or 2021.

(7)Represents the weighted cumulative total return on $100 invested as of the last day of public trading in fiscal year 2020 through the last day of public trading in the applicable fiscal year for which the cumulative total return is reported, weighted according to the respective companies' stock market capitalization at the beginning of each period for which a return is indicated. The peer group used for this purpose is the Russell 2000 Growth Biotechnology Subsector Index for all four fiscal years disclosed, which is the same peer group used in our Annual Report on Form 10-K for each of these years for purposes of Item 201(e) of Regulation S-K. The return of this index is calculated assuming reinvestment of dividends during the period presented.

(8)The dollar amounts reported represent the amount of net income (loss) reflected in our Annual Report on Form 10-K for the applicable year.

(9)The dollar amounts reported represent the amount of revenue reflected in our Annual Report on Form 10-K for the applicable year. We have identified revenue as our company selected measure ("CSM") as we believe it represents the most important financial performance measure used to link compensation actually paid to our NEOs to Company performance.

**Proposal 3—Amendment and Restatement of the 2015 Stock Plan**

At the Annual Meeting, stockholders will be asked to approve the adoption of the Amended and Restated 2015 Stock Incentive Plan, which was adopted by our Board on April 22, 2026 (the "Amended 2015 Stock Plan"). The 2015 Stock Plan was originally adopted by our Board on March 5, 2015, and approved by Novavax stockholders on June 18, 2015, with an amendment thereto approved by our stockholders on June 9, 2016, and an amendment and restatement thereof approved by our stockholders on each of June 15, 2017, June 14, 2018, June 28, 2019, June 25, 2020, June 17, 2021, June 16, 2022, and July 11, 2023. Currently, 27,470,000 shares are authorized for issuance under the 2015 Stock Plan.

As discussed further below, stockholders are being asked to approve the Amended 2015 Stock Plan to enable us to increase the number of shares of Common Stock available for issuance pursuant to awards under the plan (including pursuant to the exercise of incentive stock options) by 9,400,000 shares.

&nbsp;&nbsp;**If stockholders do not approve this proposal, the Amended 2015 Stock Plan will not become effective and our 2015 Stock Plan will remain in effect in accordance with its terms.**<br>

Equity grants are an essential element of our compensation program. Stockholder approval of the Amended 2015 Stock Plan will allow us to continue to attract and retain high quality and high performing directors, executives, and other employees with equity incentives.

&nbsp;&nbsp;**The Company is in a critical stage for its ultimate long-term success. As we remain focused on driving both near and long-term value with our Matrix-M technology built on a lean and efficient operating model, it is essential that we continue to be able to attract, retain, and reward highly qualified talent in an extremely competitive recruitment and retention market, and our ability to grant equity awards is key to our successful retention efforts.**<br>

The Board approved the Amended 2015 Stock Plan and the additional shares of Common Stock authorized for issuance under it based upon its review and consideration of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Company's historical rates of equity award issuances

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the dilutive impact to stockholders

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• equity plan guidelines established by certain institutional investors and proxy advisory firms

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• advice provided by Pearl Meyer, the Compensation Committee's independent consultant

The Board believes that it is in the best interest of the Company's stockholders for the Company's employees (including its officers), directors, and consultants to have an ownership interest in the Company and that granting equity awards to such persons motivates them to contribute to the Company's success.

Given the emphasis placed on equity awards in the Company's compensation philosophy, we anticipate that the remaining shares of Common Stock available for issuance under the 2015 Stock Plan are not sufficient to continue implementing the Company's stock incentive program over the next year, taking into account our historical burn rate (discussed below) and certain other factors, including the Company's anticipated need to retain and attract employees with appropriate levels of experience and talent. As of April 23, 2026, our 2015 Stock Plan had 2,677,122 shares of Common Stock available for future grant as equity awards. Accordingly, on April 22, 2026, our Board approved the Amended 2015 Stock Plan, subject to stockholder approval, to increase the number of shares of Common Stock reserved for issuance under the Amended 2015 Stock Plan by 9,400,000 shares and to increase the number of shares of Common Stock that may be issued under the Amended 2015 Stock Plan upon the exercise of incentive stock options by 9,400,000 shares. The Amended 2015 Stock Plan is being submitted to the Company's stockholders for approval.

**Executive Officers and Compensation**

The Board believes the Amended 2015 Stock Plan continues to promote the interests of our stockholders and continues to be consistent with principles of good corporate governance including:

![02_NVAX_Ticker_Check.jpg](nvax-20260427_g63.jpg)&nbsp;&nbsp;&nbsp;&nbsp;***Independent Committee.*** The Amended 2015 Stock Plan will continue to be administered by the Compensation Committee and its authorized delegates. The Compensation Committee is composed entirely of independent directors who meet the Nasdaq Global Select Market ("Nasdaq") standards for independence and "non-employee directors" under Rule 16b-3(b)(3) of the Exchange Act.

![02_NVAX_Ticker_Check.jpg](nvax-20260427_g63.jpg)&nbsp;&nbsp;&nbsp;&nbsp;***Stockholder Approval is Required for Additional Shares.*** The Amended 2015 Stock Plan does not contain an annual "evergreen" provision. The Amended 2015 Stock Plan authorizes a fixed number of shares and, as a result, stockholder approval is required to issue any additional shares under awards under the Amended 2015 Stock Plan. This gives our stockholders the opportunity to provide direct input on our equity compensation programs.

![02_NVAX_Ticker_Check.jpg](nvax-20260427_g63.jpg)&nbsp;&nbsp;&nbsp;&nbsp;***Limit on Non-Employee Director Compensation.*** Under the Amended 2015 Stock Plan, the aggregate value of all compensation paid or granted to a non-employee director for services to the Board in any year, including awards under the Amended 2015 Stock Plan and cash fees or other compensation paid outside the Amended 2015 Stock Plan in respect of such individual's service on the Board, may not exceed $1,500,000 in the case of the chairman of the Board and $1,000,000 in the case of any other non-employee director (or $1,500,000 with respect to the year in which a non-employee director commences service on the Board).

![02_NVAX_Ticker_Check.jpg](nvax-20260427_g63.jpg)&nbsp;&nbsp;&nbsp;&nbsp;***No Discounted Stock Options or SARs.*** All stock options and SARs under the Amended 2015 Stock Plan must have an exercise price or base value that is not less than the closing price of a share of Common Stock on the date of grant (or, if no closing price is reported on that date, the closing price on the immediately preceding date on which a closing price was reported).

![02_NVAX_Ticker_Check.jpg](nvax-20260427_g63.jpg)&nbsp;&nbsp;&nbsp;&nbsp;***Performance Awards.*** Under the Amended 2015 Stock Plan, the Compensation Committee may grant performance-based awards designed to reward individual and Company performance.

![02_NVAX_Ticker_Check.jpg](nvax-20260427_g63.jpg)&nbsp;&nbsp;&nbsp;&nbsp;***No Repricing.*** Other than in connection with a corporate transaction affecting the Company, the Amended 2015 Stock Plan prohibits any repricing of stock options or SARs without obtaining stockholder approval in accordance with Nasdaq requirements.

![02_NVAX_Ticker_Check.jpg](nvax-20260427_g63.jpg)&nbsp;&nbsp;&nbsp;&nbsp;***No Liberal Share Recycling.*** Shares retained or withheld by or delivered to the Company to satisfy the purchase or exercise price of (or withholding taxes applicable to) an award and the total number of shares subject to a SAR any portion of which is settled in shares reduce the number of shares available for issuance under the Amended 2015 Stock Plan. In addition, the number of shares available for delivery under the Amended 2015 Stock Plan will not be increased by any shares that have been delivered under the Amended 2015 Stock Plan that are subsequently repurchased using proceeds directly attributable to stock option exercises.

![02_NVAX_Ticker_Check.jpg](nvax-20260427_g63.jpg)&nbsp;&nbsp;&nbsp;&nbsp;***Minimum Vesting Provisions.*** The Amended 2015 Stock Plan requires a minimum vesting period of at least one year for all awards granted under the plan, subject to carve-outs for awards not exceeding five percent of the total shares of Common Stock reserved for issuance under the Amended 2015 Stock Plan and awards to non-employee directors that vest on the earlier of the one-year anniversary of the grant date and the next annual meeting of shareholders which is at least 50 weeks after the immediately preceding year's annual meeting.

![02_NVAX_Ticker_Check.jpg](nvax-20260427_g63.jpg)&nbsp;&nbsp;&nbsp;&nbsp;***Non-Discretionary Treatment of Awards on a Change in Control.*** The Amended 2015 Stock Plan provides that, upon the consummation of a corporate transaction (as described below), if an award is not assumed or substituted by the acquiring or succeeding company in such transaction, the vesting of the award will automatically accelerate, with the performance-based vesting of any award determined based on the greater of (a) assumed achievement of the applicable performance goals at 100% of target with the result prorated based on the period of the Participant's actual employment or service relationship with the Company prior to the

corporate transaction during the applicable full performance period, or (b) actual achievement of the applicable performance goals through the date of the corporate transaction.

![02_NVAX_Ticker_Check.jpg](nvax-20260427_g63.jpg)&nbsp;&nbsp;&nbsp;&nbsp;***Clawback Policy.*** Awards under the Amended 2015 Stock Plan are subject to recoupment in accordance with any applicable Company clawback or recoupment policy that may be adopted by the Board or as otherwise required by law or applicable listing standards. The Board has adopted the Clawback Policy, which provides that, if the Company is required to prepare an accounting restatement due to material errors or non-compliance with financial reporting

requirements under applicable securities laws, certain incentive-based compensation paid or awarded to covered executives will be subject to reduction and/or repayment if the amount of such compensation was calculated based on the achievement of financial results that were the subject of the restatement and the amount of such compensation that would have been received by the covered executives had the financial results been properly reported would have been lower than the amount actually awarded.

![02_NVAX_Ticker_Check.jpg](nvax-20260427_g63.jpg)&nbsp;&nbsp;&nbsp;&nbsp;***Payment of Dividends.*** The Amended 2015 Stock Plan expressly prohibits the payment of dividends or dividend equivalents on unvested awards.

**EXISTING EQUITY PLAN INFORMATION**

We maintain our 2015 Stock Plan under which we have granted equity awards since its adoption in 2015. In 2023, our Board adopted the Novavax, Inc. 2023 Inducement Plan (the "Inducement Plan"), pursuant to which equity awards may be granted to new employees in accordance with Nasdaq Listing Rule 5635(c)(4) as an inducement material to such employees entering into employment with the Company (see "Equity Compensation Plan Information" below for more information on the Inducement Plan).

In 2025, the Company granted options to purchase a total of 2,461,163 shares and 3,705,898 RSUs under the 2015 Stock Plan and did not grant any awards under the Inducement Plan. Our 2025 burn rate (which excludes shares granted under our ESPP) was determined to be 3.8%. Under our ESPP, we granted options to purchase 576,825 shares in 2025, 468,215 shares in 2024 and 196,239 shares in 2023. The following table provides information regarding the three-year average burn rate for the preceding three fiscal years (not including ESPP shares) as follows:

| Three-year average | 1579867 | 3990978 |  | 5570845 | 4.2% |

(1)Our weighted average common shares outstanding in each of the last three years was: 2025, 161,991,000; 2024, 152,190,000; and 2023, 100,768,000. Our burn rate is calculated by taking the total awards granted divided by the weighted average common shares outstanding for the relevant fiscal year.

In 2025 and through April 23, 2026, the Company granted options to purchase a total of 4,520,245 shares and 6,705,634 RSUs under our 2015 Stock Plan. In 2025 and through April 23, 2026, the Company did not grant any options to purchase shares or any RSUs under the Inducement Plan. As of April 23, 2026, our 2015 Stock Plan had 2,677,122 shares of Common Stock available for future grant as equity awards. If the Amended 2015 Stock Plan is approved, the total number of shares of Common Stock that will be available for future awards under the Amended 2015 Stock Plan will be 12,077,122, which is the sum of 9,400,000 shares, plus the number of shares currently available under the 2015 Stock Plan. If the stockholders do not approve the Amended 2015 Stock Plan, the Amended 2015 Stock Plan will not become effective, and additional awards will only be granted from the shares currently available under the 2015 Stock Plan. Equity awards have historically been granted deep within the Company employee base, demonstrating that the 2015 Stock Plan is truly a broad-based plan. All of our U.S.-based employees are eligible to receive annual equity awards, with only 44% of total annual equity awards granted to our executive officers in 2026.

Our burn rate does not include the ESPP. The number of shares issued under the ESPP in the past three years is: 2025, 576,825; 2024, 468,215; and 2023, 196,239 For more information about the ESPP, including the proposed additional shares requested to become available for issuance under the ESPP, please see Proposal 4.

**POTENTIAL DILUTION**

As of April 23, 2026, 164,427,429 shares of Common Stock were outstanding. The following table provides information regarding the number of shares subject to each type of outstanding award under the 2015 Stock Plan, the 2005 Stock Plan (though no future awards were made under such plan following the adoption of the 2015 Stock Plan), and the Inducement Plan, the number of shares of our Common Stock available for future awards under the 2015 Stock Plan and the Inducement Plan, the number of additional shares that would be available for future awards under the Amended 2015 Stock Plan, if approved by stockholders, and the dilutive impact of each to our stockholders as of April 23, 2026.

(2)Includes the Inducement Plan, pursuant to which equity awards may be granted to new employees in accordance with Nasdaq Listing Rule 5635(c)(4).

**REASONS FOR SEEKING STOCKHOLDER APPROVAL**

Our Board believes the ability to grant equity compensation to all employees has been, and will continue to be, essential to the Company's ability to attract and retain appropriately qualified and industry experienced employees and directors. Our Board also believes equity compensation motivates our employees, including our executive officers, and our directors to contribute to the achievement of our corporate objectives and encourages the alignment of their interests with the interests of our stockholders. After a review of its routine historical practice and an estimation of the Company's future growth, the Company believes the availability of 9,400,000 additional shares of Common Stock under the Amended 2015 Stock Plan would provide a sufficient number of shares to enable the Company to continue to make awards at historical average annual rates for the next two years. The Compensation Committee determined that reserving shares sufficient for approximately two years of new awards at historical grant rates is in the range of common practice within our industry. However, we cannot predict our future equity grant practices, the future price of our shares or future hiring activity with any degree of certainty at this time, and the share reserve under the Amended 2015 Stock Plan could last for a shorter or longer period of time.

**SUMMARY OF THE AMENDED 2015 STOCK PLAN**

The following summary describes the material terms of the Amended 2015 Stock Plan. This summary of the Amended 2015 Stock Plan is not a complete description of all provisions of the Amended 2015 Stock Plan and is qualified in its entirety by reference to the Amended 2015 Stock Plan, which is filed as Appendix A to this Proxy Statement.

***Purpose***

The purpose of the Amended 2015 Stock Plan is to secure for the Company and its stockholders the benefits arising from capital stock ownership by employees, officers, and directors of, as well as consultants and advisors to the Company, its parents, and its subsidiaries.

***Administration***

The Amended 2015 Stock Plan is administered by the Compensation Committee and its authorized delegates. Subject to the terms of the Amended 2015 Stock Plan, the Compensation Committee has the authority to determine the individuals to whom, and the time or times at which, awards are made, the number of shares of Common Stock subject to each award, and the terms of all awards and all award agreements; to construe the plan and the award agreements under the plan; to prescribe the forms, rules and procedures relating to the plan; to determine the form of settlement of awards (whether in cash, shares of Common Stock, or other property); and to make all other determinations and take all other actions that are, in the Compensation Committee's judgment, necessary or desirable for the administration of the Amended 2015 Stock Plan. The Compensation Committee's construction and interpretation of the terms and provisions of the Amended 2015 Stock Plan and any award agreement are final and conclusive.

***Shares Reserved***

Subject to adjustment as described below, the number of shares of Common Stock that are reserved for issuance under the Amended 2015 Stock Plan is 36,870,000 shares. Shares of Common Stock underlying any award made under the Amended 2015 Stock Plan to the extent the award expires, terminates or is forfeited, in whole or in part, without the issuance of shares become available for issuance again under the Amended 2015 Stock Plan. Shares of Common Stock that are retained or withheld by or delivered to the Company to satisfy any purchase or exercise price or tax withholding obligation, and the total number of shares of Common Stock subject to a SAR, any portion of which is settled in shares of Common Stock, are treated as issued under the Amended 2015 Stock Plan. The shares available for issuance under the Amended 2015 Stock Plan are not increased by any shares that have been delivered under the Amended 2015 Stock Plan that are subsequently repurchased using the proceeds directly attributable to stock option exercises. The closing price of a share of Common Stock as reported on Nasdaq on April 23, 2026 was $8.15 per share.

***Maximum Number of Shares Available under Incentive Stock Options***

The maximum aggregate number of shares that may be issued under the Amended 2015 Stock Plan upon the exercise of incentive stock options is 36,870,000.

***Non-Employee Director Limits***

The aggregate value of all compensation paid or granted to a non-employee director solely for services to the Board in any year, including awards under the Amended 2015 Stock Plan and cash fees or other compensation paid outside the Amended 2015 Stock Plan, may not exceed $1,500,000 in the case of the chairman of the Board and $1,000,000 in the case of any other non-employee director (or $1,500,000 with respect to the year in which a non-employee director commences service on the Board). These limitations do not apply to any compensation granted or paid to a non-employee director for his or her services to the Company other than as a non-employee director, including as a consultant or advisor.

***Eligible Participants***

The Compensation Committee may select recipients of awards from among key employees, officers, or directors of, or consultants or advisors to the Company and its parents and subsidiaries who are expected to contribute to the Company's future growth and success. Eligibility for stock options intended to be "incentive stock options" within the meaning of Section 422 of the Internal Revenue Code, (the "Code") is limited to employees of the Company or its parents and subsidiaries, in accordance with Section 422 of the Code. As of April 23, 2026, 691 employees, including all of our executive officers, 17 consultants and advisors, and 8 directors are eligible to participate in the Amended 2015 Stock Plan.

***Awards***

The Amended 2015 Stock Plan provides for grants of stock options, restricted stock, unrestricted stock, SARs, stock units, RSUs, and performance awards. Dividend equivalents may also be provided in connection with awards under the Amended 2015 Stock Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Restricted and Unrestricted Stock.*** A restricted stock award is an award of stock subject to forfeiture restrictions, while an unrestricted stock award is not subject to restrictions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Stock Options and SARs.*** The Amended 2015 Stock Plan provides for the grant of incentive stock options, non-statutory stock options and SARs. Stock options entitle the holder to acquire shares of Common Stock upon payment of the exercise price. A SAR is a right entitling the holder upon exercise to receive an amount (payable in cash or in shares of Common Stock of equivalent value) equal to the excess of the closing price of the shares of Common Stock subject to the SAR on the exercise date over the base value from which appreciation under the SAR is to be measured. The exercise price of a stock option, and the base value against which a SAR is to be measured, may not be less than the closing price (or, in the case of an incentive stock option granted to a ten percent stockholder, 110% of the closing price) of a share of Common Stock on the date of grant (or, if no closing price is reported on that date, the closing price on the immediately preceding date on which a closing price was reported). The Amended 2015 Stock Plan will be administered based on closing prices on the dates of grants (or, on the immediately preceding date on which a closing price was reported, as described above), which may differ substantially from market prices shortly following the grants. The Compensation Committee will determine when stock options or SARs become exercisable and the terms on which such awards remain exercisable. Stock options and SARs will generally have a maximum term of ten years (or, in the case of an incentive stock option granted to a ten percent stockholder, five years); however, in general, if (i) a participant holds an outstanding but unexercised stock option or SAR on the date that is ten years from the date of grant (or, in the case of a stock option or SAR with a maximum term of less than ten years, the last day of such maximum term) and has not exercised such stock option or SAR as of the regular closing time of the exchange on which shares of Common Stock are traded on the last day of the applicable term of the stock option or SAR, (ii) on such date shares of Common Stock is publicly traded, and (iii) at such time the value of a share of Common Stock (measured based on the closing price of a share of Common Stock) is greater than the exercise price or base value applicable to such stock option or SAR, such stock option or SAR to the extent then vested and exercisable will be automatically exercised on the last day of the applicable term and the number of shares of Common Stock otherwise to be delivered upon exercise of the stock option or SAR will be reduced by, in the case of a stock option, a number of shares having a value equal to the aggregate exercise price of the stock option being exercised and, in the case of a stock option or SAR, a number of shares having a value equal to the amount necessary to satisfy any applicable tax withholding obligation (but not in excess of the maximum withholding amount consistent with the award being subject to equity accounting treatment under FASB ASC Topic 718 or any successor provision).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Stock Units.*** A stock unit award is denominated in shares of Common Stock and entitles the recipient to receive stock or cash measured by the value of the shares in the future. The delivery of Common Stock or cash under a stock unit may be subject to the satisfaction of performance or other vesting conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Performance Awards.*** A performance award is an award of a stock option, SAR, restricted stock, or RSU, the vesting, settlement, or exercisability of which is subject to specified performance criteria.

***Vesting***

The Compensation Committee will determine the time or times at which awards will vest or become exercisable, provided that no award may vest prior to the first anniversary of the grant date, subject to the Compensation Committee's discretion to accelerate the vesting of an award. However, this one-year minimum vesting provision does not apply to awards to non-employee directors that vest on the earlier of the one-year anniversary of the grant date and the next annual meeting of stockholders which is at least 50 weeks after the immediately preceding year's annual meeting or to awards representing a number of shares of Common Stock not exceeding five percent of the number of shares of Common Stock that may be delivered in satisfaction of awards under the Amended 2015 Stock Plan.

***Termination of Employment or Service***

The Compensation Committee determines the effect of the termination of employment or service on an award. Unless otherwise provided by the Compensation Committee, upon a termination of employment or service, all unvested stock options and SARs will terminate, all other unvested awards will be forfeited, and vested stock options and SARs then held by the participant will remain exercisable for a period of three months, or 12 months in the case of death or disability, following such termination of employment or, in each case, until the applicable expiration date, if earlier. All stock options and SARs held by a participant, whether vested or unvested, immediately prior to the participant's termination of employment or service will terminate if such termination is for cause.

***Non-Transferability of Awards***<br>

In general, awards under the Amended 2015 Stock Plan may not be transferred except by will or the laws of descent and distribution, unless, in the case of awards other than incentive stock options, expressly permitted in the agreement evidencing the award. Awards other than incentive stock options may be transferred pursuant to a domestic relations order (within the meaning of Rule 16a-12 of the Exchange Act).

***Recovery of Compensation***

The Compensation Committee may cancel, rescind, withhold, or otherwise limit or restrict any award at any time under the Amended 2015 Stock Plan, and may provide that any proceeds from the exercise or disposition of any award, and any other amounts received in respect of any award will be subject to forfeiture and disgorgement to the Company, with interest and other related earnings, if the participant is not in compliance with the provisions of the Amended 2015 Stock Plan or the award or if the participant breaches any agreement with the Company with respect to non-competition, non-solicitation, no-hire, non-disparagement, invention assignment, confidentiality, or other restrictive covenant by which the participant is bound. The Compensation Committee also may recover any award or payments or gain with respect to any award under the Amended 2015 Stock Plan in accordance with any applicable Company clawback, recoupment or similar policy or policies, including but not limited to the Clawback Policy, as any such policy or policies may be in effect from time to time, or as otherwise required by applicable law or applicable stock exchange listing standards. The Board has adopted the Clawback Policy, which provides that, if the Company is required to prepare an accounting restatement due to material errors or non-compliance with financial reporting requirements under applicable securities laws, certain incentive-based compensation paid or awarded to covered executives will be subject to reduction and/or repayment if the amount of such compensation was calculated based on the achievement of financial results that were the subject of the restatement and the amount of such compensation that would have been received by the covered executives had the financial results been properly reported would have been lower than the amount actually awarded.

***Adjustment Provisions***

If the outstanding shares of Common Stock are exchanged for a different number or kind of shares or other securities of the Company or increased or decreased as a result of any recapitalization, reclassification, stock dividend, stock split or reverse stock split, 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 Common Stock or other securities, an appropriate and proportionate adjustment will be made to (a) the maximum number and kind of shares reserved for issuance under the Amended 2015 Stock Plan, (b) the maximum number of shares that can be issued upon exercise of incentive stock options under the Amended 2015 Stock Plan, (c) the number and kind of shares or other securities subject to any then outstanding awards under the Amended 2015 Stock Plan, and (d) the exercise or purchase prices (or base values) relating to awards and any other provision of awards affected by such change, without (in the case of stock options or SARs) changing the aggregate exercise price (or base values) for such awards.

***Change in Control***

In the event of a corporate transaction in which awards are not assumed or substituted by the acquiring or succeeding corporation (or an affiliate thereof), the Compensation Committee will provide for the accelerated vesting or delivery of shares under awards and may provide for (a) the cash-out of outstanding awards or (b) the termination of awards that are not exercised prior to the consummation of the transaction. In the event of a corporate transaction in which awards are assumed or substituted by the acquiring or succeeding corporation (or an affiliate thereof), the Compensation Committee will provide that such awards will continue in existence with appropriate adjustments or modifications. The performance-based vesting of any award will be determined based on the greater of (a) assumed achievement of the applicable performance goals at 100% of target, with the result prorated based on the period of the Participant's actual employment or service relationship with the Company prior to the corporate transaction during the applicable full performance period, or (b) actual achievement of the applicable performance goals through the date of the corporate transaction. Except as the Compensation Committee may otherwise provide in any case, all awards will terminate automatically or, in the case of restricted stock, will be forfeited automatically upon the consummation of a covered transaction other than awards that are assumed by the acquiring or succeeding corporation. In general, a corporate transaction under the Amended 2015 Stock Plan means a consolidation, merger, combination or reorganization of the Company, the sale, lease or other disposition of all or substantially all of the assets of the Company, a transaction or series of related transactions involving a person or entity, or a group of affiliated persons or entities in which such persons or entities become the owners, directly or indirectly, of securities of the Company representing more than 50% of the combined voting power of the Company's then outstanding securities other than by virtue of a merger, consolidation or similar transaction, or a dissolution or liquidation of the Company.

***Prohibition on Repricing***

Except in connection with certain corporate transactions involving the Company, the Company may not, without obtaining stockholder approval, amend the terms of outstanding stock options or SARs to reduce the exercise price or base value of such awards, cancel outstanding stock options or SARs in exchange for stock options or SARs with an exercise price or base value that is less than the exercise price or base value applicable to the original award, or cancel outstanding stock options or SARs that have an exercise price or base value greater than the closing price of a share of Common Stock on the date of such cancellation in exchange for cash or other consideration.

***Plan Amendments and Termination***

The Board may at any time, and from time to time, modify or amend the Amended 2015 Stock Plan in any respect, except that any such modification or amendment will be subject to stockholder approval to the extent required by applicable tax or securities laws or stock exchange listing requirements, and no such modification or amendment may adversely affect the rights under an award previously granted to a participant without such participant's consent. The Compensation Committee may amend outstanding award agreements only with the consent of the affected participant, except that the Administrator, without the consent of the affected participant, may amend or modify the terms and provisions of the Amended 2015 Stock Plan and of any outstanding incentive stock options granted under the Amended 2015 Stock Plan to the extent necessary to qualify any or all such stock options as incentive stock options or to the extent necessary to ensure the qualification of the Amended 2015 Stock Plan under Rule 16b-3 (if then applicable) or compliance with, or exemption from, Section 409A of the Code. The Board may at any time suspend or terminate the Amended 2015 Stock Plan except that any such suspension or termination may not adversely affect the rights under an award previously granted to a participant while the Amended 2015 Stock Plan is in effect without the consent of the affected participant. Unless sooner terminated by the Board, the Amended 2015 Stock Plan will terminate on April 19, 2034. Awards outstanding on that date will remain in force and effect in accordance with their terms.

**Executive Officers and Compensation**

**FEDERAL INCOME TAX CONSEQUENCES**

The following is a summary of some of the material federal income tax consequences associated with the grant and exercise of awards under the Amended 2015 Stock Plan under current federal tax laws and certain other tax considerations associated with awards under the Amended 2015 Stock Plan. The summary does not address tax rates or non-U.S., state, or local tax consequences, nor does it address employment tax or other federal tax consequences except as noted.

***Restricted Stock***

A participant who is awarded or purchases shares subject to a substantial risk of forfeiture generally does not have income until the risk of forfeiture lapses. When the risk of forfeiture lapses, the participant has ordinary income equal to the excess of the value of the shares at that time over the purchase price, if any, and a corresponding deduction is generally available to the Company. However, a participant may make an election under Section 83(b) of the Code to be taxed on restricted stock when it is acquired rather than later, when the substantial risk of forfeiture lapses. An 83(b) election must be made not later than thirty (30) days after the transfer of the shares to the participant and must satisfy certain other requirements. A participant who makes an effective 83(b) election will realize ordinary income equal to the value of the shares as of the time of acquisition less any price paid for the shares. A corresponding deduction will generally be available to the Company. If a participant makes an effective 83(b) election, no additional income results by reason of the lapsing of the restrictions.

For purposes of determining capital gain or loss on a sale of shares awarded under the Amended 2015 Stock Plan, the holding period in the shares begins when the participant realizes taxable income with respect to the transfer. The participant's tax basis in the shares equals the amount paid for the shares plus any income realized with respect to the transfer. However, if a participant makes an effective 83(b) election and later forfeits the shares, the tax loss realized as a result of the forfeiture is limited to the excess of what the participant paid for the shares (if anything) over the amount realized (if any) in connection with the forfeiture.

***Incentive Stock Options***

In general, a participant realizes no taxable income upon the grant or exercise of an incentive stock option. However, the exercise of an incentive stock option may result in an alternative minimum tax liability to the participant. With some exceptions, a disposition of shares purchased under an incentive stock option within two years from the date of grant or within one year after exercise produces ordinary income to the participant (and, generally, a deduction to the Company) equal to the value of the shares at the time of exercise less the exercise price. Any additional gain recognized on the disposition is treated as a capital gain, for which the Company is not entitled to a deduction. If the participant does not dispose of the shares until after the expiration of these one-and two-year holding periods, any gain or loss recognized upon a subsequent sale is treated as a long-term capital gain or loss, for which the Company is not entitled to a deduction.

***Non-statutory Stock Options***

In general, a participant has no taxable income upon the grant of a non-statutory stock option but realizes income in connection with exercise of the option in an amount equal to the excess (at time of exercise) of the value of the shares acquired upon exercise over the exercise price. A corresponding deduction is generally available to the Company. Upon a subsequent sale or exchange of the shares, any recognized gain or loss is treated as a capital gain or loss for which the Company is not entitled to a deduction. An incentive stock option that is exercised more than three months after termination of employment (other than termination by reason of death) is generally treated as a non-statutory stock option. Incentive stock options are also treated as non-statutory stock options to the extent they first become exercisable by an individual in any calendar year for shares having a value (determined as of the date of grant) in excess of $100,000.

**Executive Officers and Compensation**

***SARs***

The grant of a SAR does not itself result in taxable income, nor does taxable income result merely because a SAR becomes exercisable. In general, a participant who exercises a SAR for shares of stock or receives payment in cancellation of a SAR will have ordinary income equal to the amount of any cash and the value of any stock received, less any applicable base value. A corresponding deduction is generally available to the Company.

***Restricted Stock Units***

The grant of an RSU does not itself result in taxable income. Instead, the participant is taxed upon delivery of the underlying shares (and a corresponding deduction is generally available to the Company). If the shares delivered are restricted for tax purposes, the participant will be subject to the rules described above for restricted stock.

***Section 162(m)***

Section 162(m) limits to $1 million the amount a company may deduct for compensation paid to certain current and former executive officers, subject to limited exceptions.

***Certain Change in Control Payments***

Under Section 280G of the Code, the vesting or accelerated exercisability of stock options or the vesting and payment of other awards in connection with a change in control of a corporation may be required to be valued and taken into account in determining whether participants have received compensatory payments contingent on the change in control in excess of certain limits. If these limits are exceeded, a substantial portion of amounts payable to the participant, including income recognized by reason of the grant, vesting, or exercise of awards, may be subject to an additional 20% federal tax and may be non-deductible to the Company.

**NEW PLAN BENEFITS**

No awards under the Amended 2015 Stock Plan have been granted to date. Because future awards under the Amended 2015 Stock Plan will be granted in the discretion of the Compensation Committee, the type, number, recipients, and other terms of such awards cannot be determined at this time.

The following table sets forth the awards that were granted to our Named Executive Officers, our executive officers as a group, our non-employee directors as a group, and our other employees (who are not executive officers) as a group under the 2015 Stock Plan since its inception.

***2023 Inducement Plan***

On January 5, 2023, our Board adopted the Inducement Plan, pursuant to which equity awards may be granted to new employees in accordance with Nasdaq Listing Rule 5635(c)(4) as an inducement material to such employees entering into employment with the Company. Pursuant to the terms of the Inducement Plan, the Company may grant non-statutory stock options, restricted stock, unrestricted stock, SARs, stock units, RSUs, and performance awards to individuals who were not previously an employee or director of the Company or individuals returning to employment after a bona fide period of non-employment with the Company. The Inducement Plan allows the Company to deliver up to 1,000,000 shares, subject to adjustment as contemplated by the provisions of the Inducement Plan. No equity was granted pursuant to the inducement plan during the year ended December 31, 2025.

**Proposal 4—Amendment and Restatement of the ESPP**

At the Annual Meeting, stockholders will be asked to approve the ESPP, as amended and restated, adopted by our Board on April 22, 2026 (the "Amended ESPP"). The ESPP was originally adopted by our Board on April 11, 2013, and approved by Novavax stockholders on June 13, 2013. As discussed further below, stockholders are being asked to approve the Amended ESPP to enable us to increase the number of shares of our Common Stock available for issuance pursuant to awards under the ESPP by 1,000,000 shares and respectively increase the overall cap on the shares available for issuance under the ESPP, such that the number of shares available for issuance under the Amended ESPP will be the lesser of (a) 3,375,888 shares of Common Stock increased on January 1 of each year by 5% of the share pool on such January 1 (rounded down to the nearest whole share) and (b) 4,820,564 shares of Common Stock. If stockholders approve the Amended ESPP, immediately following such approval there will be 3,375,888 shares available for issuance under the ESPP, which is eligible to be increased on January 1 of each year by 5% of the share pool subject to the overall cap of 4,820,564 shares.

The purpose of the Amended ESPP is to enable eligible employees of the Company to use payroll deductions to purchase shares of our Common Stock and thereby enhance the sense of participation in the affairs of the Company. Our Board believes that providing eligible employees with the opportunity to acquire an ownership interest in the Company has been, and will continue to be, essential to the Company's ability to attract and retain appropriately qualified and industry experienced employees. Our Board also believes that the ownership of shares of our Common Stock by our employees motivates our employees to contribute to the achievement of our corporate objectives and our success.

We do not believe that the shares of our Common Stock currently available for purchase under the ESPP are sufficient to continue offering shares for purchase under the ESPP until its expiration in 2034. As of April 23, 2026, 351,942 shares of our Common Stock were available for purchase under the ESPP. Accordingly, on April 23, 2026 our Board adopted the Amended ESPP, subject to stockholder approval, which will increase the number of shares of our Common Stock reserved for purchase under the ESPP by 1,000,000 shares, such that the number of shares available for issuance under the Amended ESPP will be the lesser of (a) 3,375,888 shares of Common Stock increased on January 1 of each year by 5% of the share pool on such January 1 (rounded down to the nearest whole share) and (b) 4,820,564 shares of Common Stock (the "Share Increase"). In establishing the Share Increase, our Board considered the potential dilutive impact to stockholders and the projected participation rate over the remaining term of the plan based on historic rates of participation in the ESPP. For information about options and RSUs outstanding under our existing equity plans and the number of shares available for issuance under such plans, each as of December 31, 2025, please see "Equity Compensation Plan Information" elsewhere in this Proxy Statement. For additional information about dilution related to our equity compensation plans, please see Proposal 3.

**SUMMARY OF THE AMENDED ESPP**

The following summary describes the material terms of the Amended ESPP. This summary of the Amended ESPP is not a complete description of all provisions of the Amended ESPP and is qualified in its entirety by reference to the Amended ESPP, which is filed as Appendix B to this Proxy Statement.

***Purpose***<br>

The purpose of the Amended ESPP is to enable our eligible employees and eligible employees of certain of our subsidiaries to purchase shares of our Common Stock and thereby enhance their sense of participation in the affairs of the Company. The Amended ESPP will allow eligible employees to purchase, through payroll deductions, shares of our Common Stock at a discount from the market price of the stock at the time of purchase. The Amended ESPP is intended to qualify as an employee stock purchase plan within the meaning of Section 423 of the Code.

**Executive Officers and Compensation**

***Administration***<br>

The Compensation Committee of the Board will administer the Amended ESPP, but is authorized to delegate its duties and authority to officers and employees of the Company in its discretion and to the extent permitted by applicable law. The Compensation Committee has the authority to determine eligibility under the Amended ESPP, to interpret the Amended ESPP, to prescribe forms, rules, and procedures under the Amended ESPP, to adopt, amend, rescind, administer, and interpret such forms, rules, or procedures and otherwise to do all things necessary or advisable to carry out the terms of the Amended ESPP. All determinations and decisions by the Compensation Committee regarding the interpretation and application of the Amended ESPP are final and binding on all parties.

***Stock Subject to the Amended ESPP***<br>

Subject to adjustment, as described below, the maximum aggregate number of shares of our Common Stock available for purchase under the Amended ESPP is the lesser of (a) 3,375,888 shares of Common Stock increased on January 1 of each year by 5% of the share pool on such January 1 (rounded down to the nearest whole share) and (b) 4,820,564. If any right to purchase shares under the Amended ESPP expires or terminates for any reason without having been exercised in full or ceases for any reason to be exercisable in whole or in part, the unpurchased shares of our Common Stock subject to such right will again be available for purchase under the Amended ESPP. The closing price of share of Common Stock as reported on Nasdaq on April 23, 2026 was $8.15 per share.

***Eligibility***<br>

Our employees who (i) customarily work at least 20 hours per week, (ii) customarily work more than five months in a calendar year, and (iii) have been employed by the Company no less than five business days as of the first day of an offering period are eligible to participate in the Amended ESPP. The Compensation Committee may establish additional eligibility requirements prior to the commencement of the applicable offering period. An employee who is an eligible employee on the first day of an offering period may elect to participate in the Amended ESPP for such offering period. Approximately 528 employees were eligible to participate in the Amended ESPP as of April 23, 2026, including all of our executive officers.

***Offerings; Purchase Dates***<br>

Unless otherwise determined by the Board, offering periods under the Amended ESPP will be consecutive and overlapping 24-month periods that commence every six months on August 1 and February 1 and end 24 months later on July 31 or January 31, with each offering period having four six-month purchase periods that commence on August 1 or February 1 and end on January 31 or July 31 each year during the offering period, unless the offering period is terminated earlier. Purchases under the Amended ESPP will be made on the last day of each purchase period (the "purchase date"). Our Compensation Committee may change the frequency and duration of offering periods, purchase periods and purchase dates with respect to offering periods that have not yet commenced, in accordance with Section 423 of the Code. Our Compensation Committee may also amend the terms of the Amended ESPP or an offering, or provide for separate offerings under the Amended ESPP, in order to, among other things, reflect the impact of local law for eligible employees outside of the U.S., and may establish one or more sub-plans to reflect any amended provisions.

On a purchase date, a participant's accumulated payroll deductions withheld during the purchase period will be applied to purchase the maximum number of whole shares of our Common Stock that can be purchased with such funds, subject to the limitations described below under Limitations on Purchase and Participation.

**Executive Officers and Compensation**

***Participation***<br>

Eligible employees may become participants in the Amended ESPP by completing an enrollment agreement and filing it with us no later than five business days before the first day of an offering period (unless the Compensation Committee has set a later time for the filing of such subscription agreement). A participant may participate in only one offering period at any time.

Employees electing to participate in the Amended ESPP will authorize us to deduct after-tax dollars from their compensation each payroll period during an offering period. Participants may authorize no more than 15% (in whole percentages) of their compensation to be withheld through payroll deductions. A participant's accumulated payroll deductions will be applied to the purchase of the maximum number of whole shares that may be purchased on each semi-annual purchase date during the offering period in which the participant participates, subject to the limitations described below under Limitations on Purchase and Participation. Compensation for purposes of the Amended ESPP includes the following forms of cash compensation paid to or earned by an employee: base wages, salary, overtime, payments for paid time off and holidays, bereavement pay, jury/witness duty pay, pay during a period of suspension, compensation deferred pursuant to Section 401(k) or Section 125 of the Code, distributions under any nonqualified deferred compensation plan and any other compensation or remuneration that the Compensation Committee or the Board approves as "compensation" in accordance with Section 423 of the Code.

***Limitations on Purchase and Participation***<br>

No employee may be offered the right to purchase shares under the Amended ESPP if, immediately after the election to participate, such employee would own stock (including stock such employee may purchase under outstanding rights under the Amended ESPP) representing 5% or more of the total combined voting power or value of all classes of our stock. In addition, no participant may be offered the right to purchase shares of our Common Stock under the Amended ESPP if the rights of the participant to purchase stock under the Amended ESPP and all employee stock purchase plans maintained by us or our subsidiaries would accrue at a rate that exceeds $25,000 (or such other maximum as may be prescribed from time to time by the Code) of the fair market value of such stock (determined at the time the right is granted) for each calendar year. A maximum of 25,000 shares may be purchased by any participant on any single purchase date.

***Purchase Price***<br>

For each purchase period, the purchase price per share of our Common Stock will be equal to 85% of the fair market value per share on the first day of the offering period or, if lower, 85% of the fair market value per share on purchase date. Under the Amended ESPP, the fair market value of a share of our Common Stock on any date will be the closing price of a share of our Common Stock on Nasdaq on the date of determination (or, if such day is not a trading day, on the immediately preceding trading day).

If the fair market value of a share of our Common Stock on a purchase date during an offering period is less than the fair market value of a share of our Common Stock on the first day of the offering period, a participant's accumulated payroll deductions for the applicable purchase period within such offering period will be applied to purchase shares of our Common Stock on the purchase date and the offering period will then terminate. A participant in the terminated offering period will automatically be enrolled in the next offering period, with the participant's payroll deductions determined by reference to the last payroll deduction authorization properly submitted by the participant to the Company in accordance with the terms of the Amended ESPP.

***Termination of Participation***<br>

Employees may end their participation in an offering period by providing written notice of such termination to the Compensation Committee no later than 15 days before a purchase date. A participant's participation in the Amended ESPP will automatically terminate upon a termination of the participant's employment with us or one of our subsidiaries or upon the participant's failure to qualify as an eligible employee. Upon a termination of the employee's participation in the Amended ESPP, such employee's payroll deductions not already used to purchase shares of our Common Stock under the Amended ESPP will be returned to the employee.

***Adjustment Provisions***<br>

In the event of certain transactions with our stockholders not involving our receipt of consideration, such as a stock split, spin-off, stock dividend, or certain recapitalizations, or, if the Board or the Compensation Committee determines that adjustments would be appropriate to prevent dilution or enlargement of benefits under the Amended ESPP, in the event of the payment of a dividend or other distribution, reorganization, merger, or other changes in corporate structure, the Board or the Compensation Committee will equitably adjust (a) the class of shares of our Common Stock issuable and the maximum number of shares of our Common Stock available under the Amended ESPP, (b) the class and number of shares of our Common Stock and the purchase price per share of our Common Stock with respect to any outstanding right to purchase shares of our Common Stock under the Amended ESPP, and (c) the class and maximum number of shares of our Common Stock that may be issued to a participant during any purchase period.

However, no such adjustment may be made unless the Board or the Compensation Committee, as applicable, is satisfied that it will not constitute a modification of the rights granted under the Amended ESPP or otherwise disqualify the Plan as an employee stock purchase plan under the provisions of Section 423 of the Code.

In the event of (i) a merger or similar transaction in which we are not the surviving corporation or that results in our stockholders ceasing to own shares of our Common Stock, (ii) a sale of all or substantially all of our assets, (iii) an acquisition resulting in ownership of more than 50% of the shares of our Common Stock by any one person (or more than one person acting as a group) that did not own more than 50% of the shares of our Common Stock immediately prior to the acquisition, or (iv) the replacement during any 12-month period of a majority of the directors of the Board by new directors whose appointment was not endorsed by a majority of the directors of the Board prior to the date of the appointment or election, each offering period then in progress will continue unless otherwise provided by the Board or the Compensation Committee, which may in its discretion (a) if the Company is merged with or acquired by another corporation, provide that each outstanding offering will be assumed or exchanged for a substitute right granted by the acquirer or successor corporation, (b) cancel each offering period then in progress and return any unused payroll deductions to the participants, or (c) terminate any and all purchase periods on or before the date of the proposed transaction. In the event of our proposed dissolution or liquidation, each offering period then in progress will be cancelled immediately prior to the consummation of such dissolution or liquidation and accumulated payroll deductions will be returned to participants, unless our Compensation Committee or the Board provides otherwise in its sole discretion.

***Amendment and Termination of the ESPP***<br>

The Board may at any time and for any reason amend, suspend, or terminate the Amended ESPP. In general, no amendment may affect an offering period in progress at the time of the amendment or may adversely affect the rights of any participant without such participant's consent unless such amendment is required to satisfy the requirements of Section 423 of the Code, is made in connection with a transaction described above under "Adjustment Provisions," or is determined by the Board to be advisable in the event of changes to the financial accounting treatment for the Amended ESPP (as described below). Additionally, no amendment may be made without approval of our stockholders within 12 months of its adoption by the Board if such amendment would increase the number of shares that may be issued under the Amended ESPP or change the designation of the corporations whose employees (or class of employees) are eligible to participate in the Amended ESPP or otherwise would be treated as the adoption of a new plan under Section 423 of the Code.

Without stockholder consent and without regard to whether any participant rights may be considered to have been "adversely affected," the Board is entitled to make such amendments to the Amended ESPP as it determines are advisable if the continuation of the Amended ESPP or any offering period would result in financial accounting treatment for the Amended ESPP that is different from the financial accounting treatment in effect on the date the Amended ESPP was initially adopted by the Board.

No offers to purchase shares of our Common Stock may be granted under the Amended ESPP after April 19, 2034.

**FEDERAL INCOME TAX INFORMATION**

The following is a general summary under current law of the material federal income tax consequences to participants in the Amended ESPP. This summary deals with the general tax principles that apply and is provided only for general information. Certain types of taxes, such as state and local income taxes, are not discussed. Tax laws are complex and subject to change and may vary depending on individual circumstances and from locality to locality. The summary does not discuss all aspects of income taxation that may be relevant to a participant in light of his or her personal investment circumstances. This summarized tax information is not tax advice.

The Amended ESPP, and the right of participants to make purchases thereunder, is intended to qualify under the provisions of Section 423 of the Code.

Under the applicable Code provisions, no income will be taxable to a participant until the sale or other disposition of the shares of our Common Stock purchased under the Amended ESPP (the "ESPP shares"). Upon such sale or disposition, the participant will generally be subject to tax in an amount that depends upon the participant's holding period with respect to the ESPP shares. If the ESPP shares are sold or disposed of more than two years from the first day of the offering period and more than one year from the date of purchase, or upon the participant's death while owning the ESPP shares, the participant will recognize ordinary income measured as the lesser of (1) the excess of the fair market value of the ESPP shares at the time of such sale or disposition over the purchase price or (2) an amount equal to 15% of the fair market value of the ESPP shares as of the first day of the offering period. Any additional gain will be treated as long-term capital gain. If the ESPP shares held for the periods described above are sold and the sale price is less than the purchase price, there is no ordinary income and the participant has a long-term capital loss equal to the difference between the sale price and the purchase price.

If shares are sold or otherwise disposed of before the expiration of the holding periods described above, other than following the participant's death while owning the shares, the participant will recognize ordinary income generally measured as the excess of the fair market value of the ESPP shares on the date the ESPP shares are purchased over the purchase price. Any additional gain or loss on such sale or disposition will be long-term or short-term capital gain or loss, depending on the participant's holding period with respect to the ESPP shares. We are not entitled to a deduction for amounts taxed as ordinary income or capital gain to a participant except to the extent of ordinary income recognized upon a sale or disposition of shares prior to the expiration of the holding periods described above. We will treat any transfer of record ownership of shares as a disposition, unless we are notified to the contrary. In order to enable us to learn of dispositions prior to the expiration of the holding periods described above and ascertain the amount of the deductions to which we are entitled, participating employees will be required to notify us in writing of the date and terms of any disposition of shares purchased under the Amended ESPP.

**NEW PLAN BENEFITS**

The amounts of future stock purchases under the Amended ESPP are not determinable because, under the terms of the Amended ESPP, purchases are based upon elections made by participants. Future purchase prices are not determinable because they are based upon fair market value of shares of our Common Stock.

The following table shows the number of shares of our Common Stock that have been purchased under the ESPP by certain persons from its inception through 2025.

**AUDIT MATTERS**

**Proposal 5—Ratification of the Appointment of Ernst & Young LLP as the Company's Independent Registered Public Accounting Firm for the Fiscal Year Ending December 31, 2026**

The Audit Committee, comprised solely of independent directors, has appointed the firm Ernst & Young LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit related services. Our Board has directed that this appointment be submitted to our stockholders for ratification. Although ratification is not required by the Company's By-laws or otherwise, the Company believes it is advisable to give stockholders an opportunity to ratify this selection.

If the appointment of Ernst & Young LLP as the Company's independent auditor is ratified, the Audit Committee may, in its discretion, change the appointment at any time during the year should it determine such a change would be in the best interest of the Company and its stockholders. If the stockholders, however, do not ratify the appointment, the Audit Committee will reconsider whether to retain Ernst & Young LLP, but may proceed with the retention of Ernst & Young LLP if it deems it to be in the best interest of the Company and its stockholders.

Representatives of Ernst & Young LLP are expected to be present at the Annual Meeting and will have an opportunity to address the Annual Meeting if they desire to do so. They will also be available to respond to appropriate questions from stockholders.

**Fees and Services**

**Audit Matters**

**Audit Committee Pre-Approval Policies and Procedures**

As contemplated by applicable law and as provided by the Audit Committee's charter, the Audit Committee is responsible for the appointment, compensation, retention, and oversight of the work of the Company's independent registered public accounting firm. In connection with such responsibilities, the Audit Committee is required, and it is the Audit Committee's policy, to pre-approve the audit and permissible non-audit services (both the type and amount) performed by the Company's independent registered public accounting firm in order to ensure that the provision of such services does not impair the firm's independence, in appearance or fact.

Under the policy, unless a type of service to be provided by the independent registered public accounting firm has received general pre-approval, it will require separate pre-approval by the Audit Committee. If fees for a proposed service of a type that has been pre-approved exceed the pre-approved amount, the Audit Committee and the independent registered public accounting firm must confer, and the Audit Committee must grant its approval before further work may be performed. For audit services (including the annual financial statement audit, quarterly statement reviews, and other procedures required to be performed by the independent registered public accounting firm to be able to form an opinion on the Company's consolidated financial statements), the independent registered public accounting firm must provide to the Audit Committee in advance an engagement letter, outlining the scope of audit services

proposed to be performed with respect to the audit for that fiscal year and associated fees. If, in advance of its meeting, the Audit Committee agrees to the engagement letter, the engagement will be formally accepted by the Audit Committee at its next regularly scheduled meeting.

All permissible non-audit services not specifically approved in advance must be separately pre-approved by the Audit Committee, as noted above, with the exception of certain services of limited financial expense for which the Audit Committee has authorized the Audit Committee Chair to hire at their discretion. Generally, requests or applications to provide services must be in writing and include a description of the proposed services, the anticipated costs and fees, and the business reasons for engaging the independent registered public accounting firm to perform the services. The request must also include a statement as to whether the request or application is consistent with SEC rules on registered public accounting firm independence.

To ensure prompt handling of unexpected matters, the Audit Committee has delegated authority to pre-approve audit and permissible non-audit services between regularly scheduled meetings of the Audit Committee to its Chair, who is responsible for reporting any pre-approval decisions to the Audit Committee at its next scheduled meeting. The Audit Committee has not and will not delegate to management of the Company the Audit Committee's responsibilities to pre-approve services performed by the independent registered public accounting firm. The Audit Committee pre-approved all audit services provided to the Company by each independent registered public accounting firm engaged during the fiscal years ended December 31, 2024 and 2025.

| **Audit Committee Report**<br>The Audit Committee operates under a written charter adopted by the Board of Directors and monitors the Company's financial reporting process on behalf of the Board of Directors. This report reviews the actions taken by the Audit Committee with regard to the Company's financial reporting process during 2025 and particularly with regard to the Company's audited consolidated statements of financial condition as of December 31, 2025, and the related statements of operations, comprehensive loss, changes in stockholders' deficit, and cash flows for each of the years in the three-year period ended December 31, 2025.<br>The Audit Committee believes it has taken the actions necessary or appropriate to fulfill its oversight responsibilities under the Audit Committee's charter. In fulfilling its oversight responsibilities, the Audit Committee has reviewed and discussed the Company's audited financial statements with management and with Ernst & Young LLP, the Company's independent registered public accounting firm, the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (PCAOB) and SEC, which includes, among other items, matters related to the conduct of the audit of the Company's financial statements. The Audit Committee meets with the independent registered public accounting firm, with and without management present, to discuss the results of its examinations, its evaluations of the Company's internal controls, the overall quality of the Company's financial reporting, and their judgments as to the Company's accounting principles and such other matters as are required to be discussed with the Audit Committee in accordance with PCAOB standards. The Audit Committee has also received the written disclosures and the letter from Ernst & Young LLP required by the PCAOB independence and ethics rule, Rule 3526, "Communication with Audit Committees Concerning Independence," relating to the firm's independence from the Company and its related entities, discussed with Ernst & Young LLP its independence from the Company and considered the compatibility of the firm's provision of non-audit services with maintaining its independence. Management and the Company's internal and independent auditors also made presentations to the Audit Committee throughout the year on specific topics of interest, that include but are not limited to:<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** information technology systems, controls, and security<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** critical accounting policies<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** the impact of new accounting guidance<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** compliance with internal controls required under Section 404 of the Sarbanes-Oxley Act<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** compliance with Company's Code of Conduct<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** risk management initiatives and controls<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** significant legal matters<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** insider and related party transactions<br>Additionally, the Audit Committee discussed with the Company's internal and independent auditors the overall scope and plan for their respective audits.<br>Based on the review and discussions referred to above, the Audit Committee recommended to the Company's Board of Directors that the Company's audited financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025 for filing with the SEC. |

---

This Proxy Statement, the form of proxy, and the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the "Annual Report") are being mailed or made available to our Record Date stockholders on or about April 27, 2026.

***Why am I receiving these materials?***

The Company has made these proxy materials available to you on the Internet or, upon your request, has delivered print versions of these proxy materials to you by mail, in order to provide you with information regarding the matters on which you may vote at the Annual Meeting. You are invited to attend the live virtual webcast of the Annual Meeting and are requested to vote on the proposals described in this Proxy Statement.

***Can I access the materials on the Internet instead of receiving paper copies?***<br>

Yes, stockholders may access the Proxy Statement and the Annual Report via the Internet and vote online at www.proxyvote.com. On or about April 27, 2026, a Notice of Internet Availability of Proxy Materials (the "Notice") was mailed to stockholders of record as of the close of business on the Record Date. We are furnishing our proxy materials to our stockholders on the Internet in lieu of mailing a printed copy of our proxy materials. You will not receive a printed copy of our proxy materials unless you request one. If you would like to receive a printed or electronic copy of the proxy materials, free of charge, you should follow the instructions for requesting such materials in the Notice. The Notice instructs you as to how you may access and review on the Internet all of the important information contained in these proxy

materials or request a printed copy of those materials. The Notice also instructs you as to how you may vote your proxy.

The Company encourages stockholders to take advantage of the availability of the proxy materials on the Internet to help reduce the environmental impact of printing and mailing annual meeting materials.

***What is "householding" and how does it affect me?***

The Company has adopted the process called "householding" for mailing annual meeting materials to stockholders who share the same address. These stockholders will have received a notice from their bank, broker, or other holder of record, indicating they will receive only one copy of this Proxy Statement and Annual Report.

If you own your shares through a bank, broker, or other holder of record and wish to either stop or begin householding, you may do so, or you may request a separate copy of this Proxy Statement and Annual Report, either by contacting your bank, broker, or other holder of record at the telephone number or address provided in the above referenced notice, or contacting Novavax:

| **6** | Transaction of such other business as may properly come before the Annual Meeting or any adjournments or postponements thereof |

---

In addition, management will report on the Company's performance during fiscal year 2025 and respond to questions from stockholders.

***Who is entitled to vote?***

The only class of stock of the Company entitled to vote at the Annual Meeting is its Common Stock. Only the record holders of shares of Common Stock at the close of business on the Record Date may vote at the Annual Meeting. On the Record Date, there were 164,427,429 shares of Common Stock outstanding and entitled to be voted. Each share entitles the holder to one vote on each of the matters to be voted upon at the Annual Meeting.

***What is the quorum requirement for the Annual Meeting?***

A quorum must be present at the Annual Meeting for any business to be conducted. The presence at the Annual Meeting, in person virtually or represented by proxy, of the holders of one-third (33 1/3%) of the shares of Common Stock issued and outstanding and entitled to vote on the Record Date will constitute a quorum for the transaction of business at the Annual Meeting. If a quorum is not present, (i) holders of a majority of the shares of Common Stock present in person virtually or represented by proxy at the Annual Meeting and entitled to vote or (ii) any officer entitled to preside at or to act as a secretary of the Annual Meeting have the power to adjourn the Annual Meeting. No further stockholder notification of the adjournment is required, so long as such adjournment is less than 30 days and a new record date is not fixed. At any adjourned meeting at which a quorum is present, any business may be transacted that might have been transacted at the Annual Meeting as originally scheduled. Abstentions and broker non-votes will count in determining whether a quorum is present at the Annual Meeting.

***Why is the Company holding a virtual Annual Meeting?***

In an effort to encourage greater stockholder participation at our Annual Meeting, this year's Annual Meeting will be held in a virtual meeting format only. We have designed our virtual format to enhance, rather than constrain, stockholder access, participation, and communication. For example, the virtual format allows stockholders to communicate with us in advance of, and during, the Annual Meeting so they can ask questions of our Board of Directors or management. Similar to our in-person meetings, we may answer questions as they come in during the live Q&A session of the Annual Meeting, as well as address questions in advance, to the extent relevant to the business of the Annual Meeting as time permits.

**Information about the Annual Meeting and Voting**

16-digit control number in order to vote your shares during the Annual Meeting. If you are unable to obtain a legal proxy to vote your shares, you will still be able to attend the Annual Meeting (but will not be able to vote your shares) so long as you demonstrate proof of stock ownership such as a copy of your proxy card, voter instruction card, Notice of Internet Availability, or brokerage statement showing proof of your ownership of Common Stock as of April 23, 2026. Instructions on how to connect and participate via the Internet, including how to demonstrate proof of stock ownership, are posted at www.virtualshareholder meeting.com/NVAX2026.

***What is the difference between a stockholder of record and a beneficial owner of shares held in street name?***<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Stockholder of Record.** If your shares are registered directly in your name with the Company's transfer agent, Computershare, Inc., you are considered the stockholder of record with respect to those shares, and the proxy materials were sent directly to you by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Beneficial Owner of Shares Held in Street Name.** If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the "beneficial owner" of shares held in "street name." As a beneficial owner, you have the right to instruct your broker, bank, or other nominee how to vote your shares.

***How does discretionary voting authority apply?***

All properly executed proxies will be voted in accordance with the instructions of the stockholder. If you are a stockholder of record and you sign and return a proxy card without giving specific instructions, then the persons named as proxy holders, John C. Jacobs and Mark J. Casey, will vote your shares in the manner recommended by the Board on all matters presented in this Proxy Statement and as the proxy holders may determine in their discretion with respect to any other matters properly presented for a vote at the Annual Meeting, including any floor proposals.

Broker non-votes occur when a beneficial owner of shares held in street name does not give instructions to the broker, bank, or other nominee holding the shares as to how to vote on matters deemed "non-routine." Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the broker, bank, or other nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker, bank, or other nominee can still vote the shares with respect to matters that are considered to be "routine," but not with respect to "non-routine" matters. Under the rules and interpretations of the New York Stock Exchange, which generally govern this issue regardless of the exchange on which the company is listed, "non-routine" matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, equity compensation matters, and the election of directors, even if they are not contested.

Although the determination of whether a broker, bank, or other nominee will have discretionary voting power for a particular matter is typically determined only after proxy materials are filed with the SEC, we expect that your broker, bank, or other nominee will be permitted to vote your shares only with respect to the ratification of the appointment of Ernst & Young LLP as the Company's independent auditor for the year ending December 31, 2026 (Proposal 5), even if they do not receive instructions from you in a timely manner, so long as they hold your shares in their name and have requested your instructions. Furthermore, we do not expect your broker, bank, or other nominee to have authority, discretionary or otherwise, to vote your shares for the election of directors, the approval, on an advisory basis of the compensation of our Named Executive Officers, the amendment of the 2015 Stock Plan, or the amendment of the ESPP (Proposals 1, 2, 3 and 4), unless they receive proper instructions to do so from you in a timely manner.

In order to minimize the number of broker non-votes, the Company encourages you to vote or to provide voting instructions with respect to each proposal to the organization that holds your shares by carefully following the instructions provided in the proxy card or voting instruction form.

**Appendix A**

**APPENDIX A: NOVAVAX, INC. 2015 STOCK INCENTIVE PLAN AMENDED AND RESTATED APRIL 22, 2026**<br>

**NOVAVAX, INC.**

**2015 STOCK INCENTIVE PLAN**

**AMENDED AND RESTATED APRIL 22, 2026**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.<u>Purpose</u>.

The purpose of the Plan is to secure for the Company and its stockholders the benefits arising from capital stock ownership by employees, officers and directors of, and consultants or advisors to, the Company. Capitalized terms and operational rules related to such terms not otherwise defined in the Plan are defined on <u>Exhibit A</u>, which is incorporated herein by reference.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.<u>Type of Stock Awards and Administration</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)*<u>Types of Stock Awards</u>*. The Plan provides for the grant of Options (including Incentive Stock Options and Non-Statutory Options), Restricted Stock, Unrestricted Stock, Stock Appreciation Rights (or SARs), Stock Units, Restricted Stock Units (or RSUs) and Performance Awards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)*<u>Administration</u>.*

&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)The Plan will be administered by the Administrator, whose construction and interpretation of the terms and provisions of the Plan and any Award Agreement shall be final and conclusive. The Administrator may in its sole discretion grant Stock Awards with respect to shares of Common Stock and direct the Company to issue shares of Common Stock upon the grant, vesting or exercise of such Stock Awards as provided in 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;(ii)Subject to the express provisions of the Plan, the Administrator shall have authority:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)To determine the individuals to whom, and the time or times at which, Stock Awards are made, the number of shares subject to each Stock Award and the terms of all Stock Awards and Award Agreements, which need not be identical;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)To construe the Plan and Award Agreements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)To prescribe forms, rules and procedures relating to 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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)To determine the form of settlement of Stock Awards (whether in cash, shares of Common Stock or other property); 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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5)To make all other determinations and take all other actions that are, in the judgment of the Administrator, necessary or desirable for the administration of the Plan.

------

**Appendix A**<br>

&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 Administrator may correct any defect, supply any omission or reconcile any inconsistency in the Plan or in any Award Agreement (or any inconsistency between the Plan and any Award Agreement) in the manner and to the extent it shall deem expedient to carry the Plan into effect and it shall be the sole and final judge of such expediency. No director or individual acting pursuant to authority delegated by the Administrator shall be liable for any action or determination under the Plan made in good faith.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.<u>Participant Eligibility</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)*<u>General</u>*. The Administrator may select Participants from among key employees, officers or directors of, or consultants or advisors to, the Company who are expected to contribute to the Company's future growth and success; <u>provided</u>, <u>however</u>, that the class of persons to whom Incentive Stock Options may be granted shall be limited to employees of the Company, and <u>provided</u>, further, that persons to whom Non-Statutory Options or SARs may be granted shall be limited to persons employed by or providing services to the Company and its "qualifying subsidiaries." For these purposes, a "qualifying subsidiary" means a subsidiary in which the Company owns a "controlling interest" as described in Treasury Regulations §1.409A-1(b)(5)(iii)(E)(1).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)*<u>Grant of Stock Awards to Directors and Officers</u>*. In the discretion of the Administrator, the selection of a director or officer (as defined for purposes of Rule 16b-3) as a Participant, and the terms of any Stock Award granted to such Participant, including the grant date, the purchase or exercise price, the number of shares underlying the Stock Award and other terms and conditions, shall be determined either (i) by the Board, of which all members shall be "non-employee directors" (as hereinafter defined) or (ii) by the Compensation Committee, consisting of two or more directors having full authority to act in the matter, each of whom shall be a "non-employee director" (with any action of the Compensation Committee subject to approval or ratification by the Board, if required). For the purposes of the Plan, a director shall be deemed to be a "non-employee director" only if such director qualifies as a "non-employee director" within the meaning of Rule 16b-3.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.<u>Stock Subject to Plan</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)*<u>Number of Shares</u>*. Subject to adjustment as provided in Section 10 below, the maximum number of shares of Common Stock that may be delivered in satisfaction of Stock Awards under the Plan shall be 36,870,000 shares. Subject to adjustment as provided in Section 10 below, the maximum aggregate number of shares that may be issued upon the exercise of Incentive Stock Options shall in no event exceed 36,870,000 shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)*<u>Reversion of Shares to the Share Reserve</u>*. Shares of Common Stock underlying any Stock Award to the extent the Stock Award, for any reason, expires, terminates or is forfeited, in whole or in part, without the issuance of shares, shall revert to and again become available for issuance under the Plan. Shares of Common Stock that are retained or withheld by or delivered to the Company to satisfy any purchase or exercise price or tax withholding obligation, and the total number of shares of Common Stock subject to a SAR any portion of which is settled in shares of Common Stock, will be treated as issued under the Plan. The shares of Common Stock available for issuance pursuant to Section 4(a) will not be increased by any shares that have been delivered under the Plan that are subsequently repurchased using the proceeds directly attributable to stock option exercises.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)*[Reserved.]* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)*<u>Non-employee Director Limits</u>.* Notwithstanding any other provision of the Plan to the contrary, effective January 1, 2022, the aggregate value of all compensation paid or granted to a Participant who is a non-

------

**Appendix A**

employee director with respect to any calendar year, including Stock Awards under the Plan and cash fees or other compensation paid by the Company to such director outside the Plan, solely with respect to his or her services as a director during such calendar year, may not exceed $1,500,000 in the case of the Chairman of the Board or $1,000,000 in the case of any other non-employee director (except with respect to the initial calendar year in which a non-employee director commences service on the Board, such annual limit shall be $1,500,000). In applying the foregoing limits, the value of any Stock Awards is calculated based on the grant date fair value in accordance with the Accounting Rules, assuming a maximum payout. For the avoidance of doubt, the limitation in this Section 4(d) will not apply to any compensation granted or paid to a non-employee director for his or her services to the Company or a subsidiary other than as a non-employee director, including without limitation, as a consultant or advisor to the Company or a subsidiary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.<u>Provisions Applicable to Options and Stock Appreciation Rights</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)*<u>Forms of Award Agreements</u>*. As a condition to the grant of an Option or SAR under the Plan, each recipient of an Option or SAR shall execute an Award Agreement in such form not inconsistent with the Plan as may be approved by the Administrator. Such Award Agreements may differ among Participants and among Stock Awards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)*<u>Exercise Price and Base Value</u>.* Subject to Section 3(b), the exercise price, or base value from which appreciation is to be measured, per share of Common Stock subject to a Stock Option or SAR, as applicable, shall be determined by the Administrator; <u>provided</u>, <u>however</u>, that the exercise price of an Option or base value of a SAR shall not be less than 100% of the Fair Market Value of a share of Common Stock at the time of grant of such Option or SAR, or less than 110% of such Fair Market Value in the case of an Incentive Stock Option granted to a Participant described in Section 6(b). Except in connection with a corporate transaction involving the Company (which term shall include, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination, or exchange of shares) or as otherwise contemplated by Section 10 or Section 11 of the Plan, the Company may not, without obtaining stockholder approval in accordance with the applicable requirements of the NASDAQ Global Select Market, (A) amend the terms of outstanding Stock Options or SARs to reduce the exercise price or base value of such Stock Options or SARs, (B) cancel outstanding Stock Options or SARs in exchange for Stock Options or SARs with an exercise price or base value that is less than the exercise price or base value of the original Stock Options or SARs, or (C) cancel outstanding Stock Options or SARs that have an exercise price or base value greater than the Fair Market Value of a share of Common Stock on the date of such cancellation in exchange for cash or other consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)*<u>Payment of Exercise Price</u>*. Payment of the exercise price of Options granted under the Plan shall be made by delivery of cash or a check to the order of the Company in an amount equal to the exercise price of such Options or through a broker-assisted exercise program acceptable to the Administrator, or, to the extent legally permissible and acceptable to the Administrator, (i) by delivery to the Company of shares of Common Stock of the Company already owned by the Participant having a Fair Market Value equal in amount to the exercise price of the Options being exercised, (ii) through the withholding of shares of Common Stock otherwise to be delivered upon exercise of the Option having a Fair Market Value equal to the aggregate exercise price of the Option being exercised, or (iii) by any other means approved by the Administrator. The fair market value of any non-cash consideration which may be delivered upon exercise of an Option shall be determined by the Administrator.

------

**Appendix A**<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)*<u>Maximum Term</u>*. Except as otherwise provided in Section 6 regarding Incentive Stock Options, Options and SARs will have a maximum term of 10 years from the date of grant, subject to earlier termination as provided in the Plan or the applicable Award Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)*<u>Exercise of Options and SARs</u>*. Unless the Administrator expressly provides otherwise, no Option or SAR will be deemed to have been exercised until the Administrator receives a notice of exercise (in form acceptable to the Administrator), which may be an electronic notice, signed (including electronic signature in form acceptable to the Administrator) by the appropriate person and, in the case of an Option, accompanied by any payment required under the Option. An Option or SAR exercised by any person other than the Participant will not be deemed to have been exercised until the Administrator has received such evidence as it may require that the person exercising the Stock Award has the right to do so. Notwithstanding the foregoing, unless otherwise provided by the Administrator in an Award Agreement, if (i) a Participant holds an outstanding but unexercised Option or SAR on the date that is ten (10) years from the date of grant (or, in the case of an Option or SAR with a maximum term of less than ten (10) years, the last day of such maximum term) and has not exercised such Option or SAR as of the regular closing time of the exchange on which the Common Stock is traded on the last day of the applicable term of the Option or SAR, (ii) on such date the Common Stock is publicly traded, and (iii) at such time the Fair Market Value of a share of Common Stock is greater than the exercise price or base value applicable to such Option or SAR, such Option or SAR, to the extent then vested and exercisable, shall be automatically exercised on the last day of the applicable term, and the number of shares of Common Stock otherwise to be delivered upon exercise of the Option or SAR shall be reduced by, in the case of an Option, a number of shares having a Fair Market Value equal to the aggregate exercise price of the Option being exercised and, in the case of an Option or SAR, a number of shares having a Fair Market Value equal to the amount necessary to satisfy any applicable tax withholding obligation (but not in excess of the maximum withholding amount consistent with the award being subject to equity accounting treatment under the Accounting Rules).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)*<u>Vesting and Effect of Termination of Employment or Other Service Relationship</u>*. Subject to Section 8(b) below, the Administrator will determine the time or times at which an Option or SAR will vest or become exercisable and the terms on which an Option or SAR will remain exercisable. Unless the Administrator expressly provides otherwise, however, the following rules will apply when a Participant's employment or other service relationship with the Company ceases:

&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)Immediately upon the cessation of the Participant's employment or other service relationship and except as provided in (ii) and (iii) below, each Option or SAR that is then held by the Participant or by the Participant's permitted transferees, if any, will cease to be exercisable and will terminate.

&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)Subject to (iii) and (iv) below, all Options and SARs held by the Participant or the Participant's permitted transferees, if any, immediately prior to the cessation of the Participant's employment or other service relationship with the Company, to the extent then exercisable, will remain exercisable for the lesser of (i) a period of three months or (ii) the period ending on the latest date on which such Option or SAR could have been exercised without regard to this Section 5(f)(ii), and will thereupon immediately terminate.

&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)All Options and SARs held by a Participant or the Participant's permitted transferees, if any, immediately prior to (A) the cessation of the Participant's employment or other service relationship due to his or her death or disability (within the meaning of Section 22(e)(3) of the Code or any successor provision thereto) or (B) the Participant's death within three months following the Participant's termination of employment, to the extent then exercisable, will remain exercisable for the lesser of (i) a period of twelve (12) months or (ii) the period ending

------

**Appendix A**

on the latest date on which such Option or SAR could have been exercised without regard to this Section 5(f)(iii), and will thereupon immediately terminate.

&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)All Options and SARs (whether or not exercisable) held by a Participant or the Participant's permitted transferees, if any, immediately prior to the cessation of the Participant's employment or other service relationship with the Company will immediately terminate upon such cessation of employment or other service relationship if the termination is for Cause.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.<u>Special Provisions for Incentive Stock Options</u>.

Options granted under the Plan which are intended to be Incentive Stock Options shall be subject to the following additional terms and conditions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)*<u>Express Designation</u>*. All Incentive Stock Options granted under the Plan shall, at the time of grant, be specifically designated as such in the Award Agreement evidencing the grant of Incentive Stock Options.

&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)the exercise price per share of the Common Stock subject to such Incentive Stock Option shall not be less than 110% of the Fair Market Value of one share of Common Stock at the time of grant; 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;(ii)the Option may not be exercisable after the expiration of five years from the date of grant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)*<u>Dollar Limitation</u>*. For so long as the Code shall so provide, Options granted to any employee under the Plan (and any other incentive stock option plans of the Company) which are intended to be Incentive Stock Options shall not be Incentive Stock Options to the extent that such Options, in the aggregate, become exercisable for the first time in any one calendar year for shares of Common Stock with an aggregate Fair Market Value (determined as of the respective date or dates of grant) of more than $100,000.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)*<u>Continuous Employment</u>*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)*<u>Award Provisions</u>*. The Administrator will determine the terms of all Stock Awards, subject to the limitations provided in the Plan. By accepting (or, under such rules as the Administrator may prescribe, being deemed to have accepted) a Stock Award, the Participant will be deemed to have agreed to the terms of the Stock Award and the Plan. Notwithstanding any provision of this Plan to the contrary, awards of an acquired company that are converted, replaced or adjusted in connection with the acquisition may contain terms and conditions that are inconsistent with the terms and conditions specified herein, as determined by the Administrator.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)*<u>Vesting</u>*. Notwithstanding anything provided in Section 5(f), Section 7(a)(iii), Section 7(b)(ii) or Section 11 hereof, no Stock Award shall vest prior to the first anniversary of the grant date; <u>provided</u>, <u>however</u>, that (i) a number of shares of Common Stock not exceeding 5% of the number of shares of Common Stock that may be delivered in satisfaction of Stock Awards may be delivered in satisfaction of Stock Awards that are not subject to this one-year minimum vesting period and (ii) this one-year minimum vesting period shall not apply to Stock Awards granted to non-employee directors that vest on the earlier of the one-year anniversary of the date of grant and the next annual meeting of stockholders which is at least 50 weeks after the immediately preceding year's annual meeting. Nothing in this Section 8(b) shall preclude the Administrator from taking action, in its sole discretion, to accelerate the vesting of any Stock Award (or any portion thereof), including pursuant to Section 11 below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)*<u>Nontransferability of Stock Awards</u>*. Except as provided in this Section 8(c), Stock Awards shall not be assignable or transferable by the person to whom they are granted, either voluntarily or by operation of law, other than by will or the laws of descent and distribution, and, in the case of Options and SARs, during the life of the Participant, shall be exercisable only by the Participant. Awards, other than Incentive Stock Options, may be transferred pursuant to a domestic relations order (within the meaning of Rule 16a-12 promulgated under the Exchange Act) or as otherwise expressly permitted by the Administrator in the applicable Award Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)*<u>Investment Representations</u>*. The Company may require any person to whom a Stock Award is granted, as a condition of receiving or exercising such Stock Award, as applicable, to give written assurances in substance and form satisfactory to the Company to the effect that such person is acquiring the Common Stock subject to the Stock Award for his or her own account for investment and not with any present intention of selling or otherwise distributing the same, and to such other effects as the Company deems necessary or appropriate in order to comply with federal and applicable state securities laws, or with covenants or representations made by the Company in connection with any public offering of its Common Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)*<u>Compliance with Securities Laws</u>*. Each Stock Award shall be subject to the requirement that if, at any time, counsel to the Company shall determine that the listing, registration or qualification of the shares subject to such Stock Award upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, or that the disclosure of non-public information or the satisfaction of any other condition is necessary as a condition of, or in connection with, the issuance or purchase of shares thereunder, such Stock Award may not be issued or exercised, as applicable in whole or in part, unless such listing, registration, qualification, consent or approval, or satisfaction of such condition shall have been effected or obtained on conditions acceptable to the Administrator. Nothing herein shall be deemed to require the Company to apply for or to obtain such listing, registration or qualification, or to satisfy such condition.

------

**Appendix A**<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)*<u>Additional Restrictions</u>.* The Administrator may cancel, rescind, withhold or otherwise limit or restrict any Stock Award at any time, and may provide that any proceeds from the exercise or disposition of any Stock Award, and any other amounts received in respect of any Stock Award will be subject to forfeiture and disgorgement to the Company, with interest and other related earnings, if the Participant is not in compliance with all applicable provisions of the applicable Award Agreement and the Plan, or if the Participant breaches any agreement with the Company with respect to non-competition, non-solicitation, no-hire, non-disparagement, invention assignment, confidentiality, or other restrictive covenant by which the Participant is bound. Without limiting the generality of the foregoing, the Administrator may recover Stock Awards made under the Plan and payments under or gain in respect of any Stock Award in accordance with any applicable Company clawback, recoupment or similar policy or policies, including the Novavax, Inc. Second Amended and Restated Recoupment Policy, as any such policy or policies may be amended and in effect from time to time, or as otherwise required by applicable law or applicable stock exchange listing standards, including, without limitation, Section 10D of the Exchange Act. In addition, each Stock Award will be subject to any policy of the Company or any of its subsidiaries that relates to trading on non-public information and permitted transactions with respect to shares of Common Stock, including limitations on hedging and pledging. Each Participant, by accepting or being deemed to have accepted a Stock Award under the Plan, agrees (or will be deemed to have agreed) to the terms of this Section 8(f) and to any clawback, recoupment or similar policy of the Company or any of its subsidiaries and further agrees (or will be deemed to have further agreed) to cooperate fully with the Administrator, and to cause any and all permitted transferees of the Participant to cooperate fully with the Administrator, to effectuate any forfeiture or disgorgement described in this Section 8(f). Neither the Administrator nor the Company nor any other person, other than the Participant and his or her permitted transferees, if any, will be responsible for any adverse tax or other consequences to a Participant or his or her permitted transferees, if any, that may arise in connection with this Section 8(f).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)*<u>Dividend Equivalents, Etc</u>.* The Administrator may provide for the payment of amounts (on terms and subject to conditions established by the Administrator) in lieu of cash dividends or other cash distributions with respect to Common Stock subject to a Stock Award whether or not the holder of such Stock Award is otherwise entitled to share in the actual dividend or distribution in respect of such Stock Award. Any entitlement to dividend equivalents or similar entitlements will be established and administered either consistent with an exemption from, or in compliance with, the requirements of Section 409A. Dividends or dividend equivalent amounts payable in respect of Stock Awards that are subject to restrictions may be subject to such limits or restrictions as the Administrator may impose. Notwithstanding the foregoing, no dividends or dividend equivalents may be paid to a Participant in connection with a Stock Award prior to the date on which such Stock Award vests.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)*[Reserved.]*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)*<u>Coordination with Other Plans</u>*. Stock Awards under the Plan may be granted in tandem with, or in satisfaction of or substitution for, other Stock Awards under the Plan or awards made under other compensatory plans or programs of the Company. For example, but without limiting the generality of the foregoing, awards under other compensatory plans or programs of the Company may be settled in Common Stock (including, without limitation, Unrestricted Stock) if the Administrator so determines, in which case the shares delivered will be treated as awarded under the Plan (and will reduce the number of shares thereafter available under the Plan in accordance with the rules set forth in Section 4).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j)*<u>Section 409A</u>*. Each Award Agreement will contain such terms as the Administrator determines, and will be construed and administered, such that the Stock Award either qualifies for an exemption from the requirements of Section 409A or satisfies such requirements.

------

**Appendix A**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.<u>Rights as a Stockholder</u>.

Nothing in the Plan will be construed as giving any person the rights as a stockholder with respect to any shares of Common Stock underlying a Stock Award (including, without limitation, any rights to receive dividends or non-cash distributions with respect to such shares) except as to shares of Common Stock actually issued under the Plan. Except as otherwise provided in an Award Agreement, no adjustment shall be made for dividends or other rights for which the record date is prior to the date such shares of Common Stock are issued.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.<u>Adjustment Provisions for Recapitalizations and Related Transactions</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)If (i) the outstanding shares of Common Stock are (A) exchanged for a different number or kind of shares or other securities of the Company or (B) increased or decreased as a result of any recapitalization, reclassification, stock dividend, stock split or reverse stock split or (ii) 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 Common Stock or other securities, an appropriate and proportionate adjustment shall be made to (1) the maximum number and kind of shares reserved for issuance under the Plan, (2) the maximum number of shares that can be issued upon exercise of Incentive Stock Options under the Plan, (3) the limitations on Stock Awards pursuant to Section 4(d), (4) the number and kind of shares or other securities subject to any then outstanding Stock Awards under the Plan, and (5) the exercise or purchase prices (or base values) relating to Stock Awards and any other provision of Stock Awards affected by such change, without (in the case of Options or SARs) changing the aggregate exercise price or base values for such Stock Awards. Any adjustment made pursuant to this Section 10 shall be made by the Administrator having due regard, where applicable, for the qualification of Incentive Stock Options under Section 422 and the requirements of Section 409A.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Any adjustments under this Section 10 will be made by the Administrator, whose determination as to what adjustments, if any, will be made and the extent thereof will be final, binding and conclusive. No fractional shares will be issued under the Plan on account of any such adjustments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11.<u>Merger, Consolidation, Asset Sale, Liquidation, etc</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)*<u>General</u>*. In the event of (i) a consolidation, merger, combination or reorganization of the Company in which outstanding shares of Common Stock are exchanged for securities, cash or other property of any other corporation or business entity, (ii) the sale, lease or other disposition of all or substantially all of the assets of the Company, (iii) a transaction or series of related transactions involving a person or entity, or a group of affiliated persons or entities (but excluding any employee benefit plan or related trust sponsored or maintained by the Company or an affiliate) in which such persons or entities become the owners, directly or indirectly, of securities of the Company representing more than fifty percent (50%) of the combined voting power of the Company's then outstanding securities (a "***Securities Acquisition***") other than by virtue of a merger, consolidation or similar transaction, or (iv) a dissolution or liquidation of the Company (hereinafter, each of the events described in (i) through (iv) above shall be a "***Corporate Transaction***"), if Stock Awards are not assumed, or equivalent stock awards are not substituted, by the acquiring or succeeding corporation (or an affiliate thereof), the Administrator will provide that all or any outstanding Stock Awards shall become vested and exercisable (or that any reacquisition or repurchase rights held by the Company shall lapse) at or immediately prior to such event, and will (1) upon written notice to the Participants, provide that all Stock Awards that are outstanding, whether vested or unvested and whether exercisable or unexercisable, including Stock Awards that are "out-of-the-money" or "underwater," will terminate immediately prior to the consummation of a Corporate Transaction, unless exercised (to the extent then

------

**Appendix A**<br>

vested and exercisable) by the Participant within a specified period following the date of such notice, if applicable, or (2) in the event of a consolidation, merger, combination, reorganization or Securities Acquisition under the terms of which holders of the Common Stock of the Company will receive upon consummation thereof a payment for each share surrendered in the transaction (the "***Sale Price***"), make or provide for a cash payment to the Participant equal to the difference between (A) the Sale Price times the number of shares of Common Stock subject to such outstanding Stock Awards (to the extent then vested or exercisable at prices not in excess of the Sale Price), and (B) the aggregate exercise price of all such outstanding Stock Awards (to the extent then vested or exercisable at prices not in excess of the Sale Price) in exchange for the termination of such Stock Awards. In the event of a Corporate Transaction, if such Stock Awards are assumed, or equivalent stock awards are substituted, by the acquiring or succeeding corporation (or an affiliate thereof), the Administrator shall provide that such Stock Awards shall continue in existence with appropriate adjustments or modifications, provided that any such options substituted for Incentive Stock Options shall meet the requirements of Section 424(a) of the Code. Notwithstanding anything to the contrary in this Section 11(a), the vesting of any performance-based Stock Awards will be determined based on the greater of (i) assumed achievement of the applicable performance goals at 100% of the performance target, as provided in the Award Agreement with the result prorated based on the period of the Participant's actual employment or other service relationship with the Company prior to the Corporate Transaction during the applicable full performance period, or (ii) actual achievement of the applicable performance goals, as provided in the Award Agreement, through the date of the consummation of the Corporate Transaction. Except as the Administrator may otherwise determine in any case, each Stock Award will automatically terminate (and in the case of outstanding shares of Restricted Stock will be forfeited automatically) upon consummation of the Corporate Transaction, other than Stock Awards assumed pursuant to clause (1) of this Section 11(a).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)*<u>Substitute Options</u>*. The Company may grant Stock Awards under the Plan in substitution for Stock Awards held by employees of another corporation who become employees of the Company, or a subsidiary of the Company, as the result of a merger, consolidation, combination or reorganization of the employing corporation with the Company or a subsidiary of the Company, or as the result of the acquisition by the Company, or one of its subsidiaries, of property or stock of the employing corporation. The Company may direct that substitute Stock Awards be granted on such terms and conditions as the Administrator considers appropriate in the circumstances.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.<u>No Employment Rights</u>.

Nothing contained in the Plan or in any Award Agreement shall confer upon any Participant any right with respect to the continuation of his or her employment or other service relationship with the Company or interfere in any way with the right of the Company at any time to terminate such employment or to increase or decrease the compensation of the Participant. The loss of existing or potential profit in a Stock Award will not constitute an element of damages in the event of a termination of a Participant's employment or other service relationship with the Company for any reason, even if the termination is in violation of an obligation of the Company to the Participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13.<u>Other Employee Benefits</u>.

Except as to plans which by their terms include such amounts as compensation or as otherwise specifically determined by the Administrator, the amount of any compensation deemed to be received by an employee as a result of the issuance of a Stock Award, the lapse of any restrictions thereon, or the exercise of an Option or SAR, or the sale of shares received upon such exercise will not constitute compensation for purposes of determining any other employee benefits of such employee, including, without limitation, benefits under any bonus, pension, profit sharing, life insurance or salary continuation plan.

**Appendix A**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14.<u>Amendment of the Plan and Stock Awards</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)The Board may at any time, and from time to time, modify or amend the Plan in any respect, except that any such modification or amendment (i) shall be subject to stockholder approval if the approval of the stockholders of the Company is required under Section 422 or any successor provision with respect to Incentive Stock Options, Rule 16b-3 (if then applicable), or any other applicable tax or securities law or stock exchange listing requirements, and (ii) shall not adversely affect the rights under any Stock Award previously granted to a Participant without the Participant's consent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)With the consent of the affected Participant, the Administrator may amend outstanding Stock Award Agreements in a manner not inconsistent with the Plan, <u>provided</u>, <u>however</u>, that, without the consent of the affected Participant, the Administrator shall have the right to amend or modify (i) the terms and provisions of the Plan and of any outstanding Incentive Stock Options granted under the Plan to the extent necessary to qualify any or all such Options for such favorable federal income tax treatment (including deferral of taxation upon exercise) as may be afforded incentive stock options under Section 422, (ii) the terms and provisions of the Plan and of any outstanding Stock Award to the extent necessary to ensure (A) the qualification of the Plan under Rule 16b-3 (if then applicable) or (B) compliance with, or exemption from, Section 409A.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15.<u>Withholding</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)The delivery, vesting and retention of Common Stock, cash or other property under a Stock Award are conditioned upon full satisfaction by the Participant of all tax withholding requirements with respect thereto. The Administrator will prescribe such rules for the withholding of taxes as it deems appropriate. The Company shall have the right to deduct from payments of any kind otherwise due to a Participant any federal, state or local taxes of any kind required by law to be withheld with respect to any shares of Common Stock issued, or cash or other property delivered, in settlement of a Stock Award, upon the exercise of Options or SARs, and upon the lapse of any restrictions with respect to a Stock Award. Subject to the prior approval of the Administrator, which may be withheld in its sole discretion, a Participant may elect (i) to cause the Company to hold back shares of Common Stock from a Stock Award or (ii) to deliver to the Company shares of Common Stock already owned by the Participant in satisfaction of tax withholding obligations but, in each case, not in excess of the maximum withholding amount consistent with the award being subject to equity accounting treatment under the Accounting Rules. The shares of Common Stock so delivered or held back shall have a Fair Market Value equal to such withholding obligation. The Fair Market Value of the shares used to satisfy such withholding obligation shall be determined by the Company as of the date that the amount of tax to be withheld is to be determined. A Participant who has made an election pursuant to this Section 15(a) may only satisfy his or her withholding obligation with shares of Common Stock which are not subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Notwithstanding the foregoing, in the case of a Reporting Person, no election to use shares for the payment of withholding taxes shall be effective unless made in compliance with any applicable requirements of Rule 16b-3 (unless it is intended that the transaction not qualify for exemption under Rule 16b-3).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16.<u>Effective Date and Duration of the Plan</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)*<u>Effective Date</u>*. The Plan is effective as of the Amendment Date, subject to its approval by the Company's stockholders at the Company's annual meeting in 2026. Amendments to the Plan not requiring

------

**Appendix A**<br>

stockholder approval shall become effective when adopted by the Board; amendments requiring stockholder approval (as provided in Section 14) shall become effective when adopted by the Board, but no Options or SARs granted after the date of such amendment shall become exercisable (to the extent that such amendment to the Plan was required to enable the Company to grant such Options or SARs). If such stockholder approval is not obtained within twelve months of the Board's adoption of such amendment, any Options or SARs granted on or after the date of such amendment shall terminate to the extent that such amendment was required to enable the Company to grant such Options or SARs. Subject to this limitation, Stock Awards may be granted under the Plan at any time after the Amendment Date and before the termination of the Plan as provided in Section 16(b) below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)*<u>Termination</u>*. The Board may suspend or terminate the Plan at any time, except that such suspension or termination of the Plan shall not adversely affect a Participant's rights under a Stock Award previously granted to the Participant while the Plan is in effect without the consent of the Participant. Unless sooner terminated in accordance with this Section or Section 11, the Plan shall terminate upon the close of business on the day immediately preceding the (10<sup>th</sup>) tenth anniversary of April 19, 2024. Stock Awards outstanding on such date shall remain in force and effect in accordance with their terms.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17.<u>Provision for Foreign Participants; Sub Plans</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)The Administrator may, without amending the Plan, modify Stock Awards granted to Participants who are foreign nationals or employed outside the United States to recognize differences in laws, rules, regulations or customs of such foreign jurisdictions with respect to tax, securities, currency, employee benefit or other matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The Board may from time to time establish one or more sub-plans under the Plan for purposes of satisfying applicable blue sky, securities or tax laws of various jurisdictions. The Board will establish such sub-plans by adopting supplements to the Plan setting forth (i) such limitations on the Board's discretion under the Plan as it deems necessary or desirable and (ii) such additional terms and conditions not otherwise inconsistent with the Plan as it deems necessary or desirable. All supplements so established will be deemed to be part of the Plan, but each supplement will apply only to Participants within the affected jurisdiction (as determined by the Administrator).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18.<u>Miscellaneous</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)*<u>Waiver of Jury Trial</u>*. By accepting a Stock Award under the Plan, each Participant waives any right to a trial by jury in any action, proceeding or counterclaim concerning any rights under the Plan and any Stock Award, or under any amendment, waiver, consent, instrument, document or other agreement delivered or which in the future may be delivered in connection therewith, and agrees that any such action, proceedings or counterclaim will be tried before a court and not before a jury. By accepting a Stock Award under the Plan, each Participant certifies that no officer, representative, or attorney of the Company has represented, expressly or otherwise, that the Company would not, in the event of any action, proceeding or counterclaim, seek to enforce the foregoing waivers. Notwithstanding anything to the contrary in the Plan, nothing herein is to be construed as limiting the ability of the Company and a Participant to agree to submit disputes arising under the terms of the Plan or any Stock Award made hereunder to binding arbitration or as limiting the ability of the Company to require any eligible individual to agree to submit such disputes to binding arbitration as a condition of receiving a Stock Award hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)*<u>Limitation of Liability</u>*. Notwithstanding anything to the contrary in the Plan, neither the Company nor the Administrator, nor any person acting on behalf of the Company or the Administrator, will be liable to any Participant or to the estate or beneficiary of any Participant or to any other holder of a Stock Award by reason of any

------

**Appendix A**

acceleration of income, or any additional tax (including any interest and penalties), by reason of the failure of a Stock Award to satisfy the requirements of Section 422 or Section 409A or by reason of Section 4999 of the Code, or otherwise asserted with respect to the Stock Award.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.<u>Governing Law</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)*<u>Certain Requirements of Corporate Law</u>*. Stock Awards will be granted and administered consistent with the requirements of applicable Delaware law relating to the issuance of stock and the consideration to be received therefor, and with the applicable requirements of the stock exchanges or other trading systems on which the Common Stock is listed or entered for trading, in each case as determined by the Administrator.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)*<u>Other Matters</u>*. Except as otherwise provided by the express terms of an Award Agreement, under a sub-plan described in Section 17(b) or as provided in Section 19(a) above, the provisions of the Plan and of Stock Awards under the Plan and all claims or disputes arising out of or based upon the Plan or any Stock Award under the Plan or relating to the subject matter hereof or thereof will be governed by and construed in accordance with the domestic substantive laws of the State of Maryland without giving effect to any choice or conflict of laws provision or rule that would cause the application of the domestic substantive laws of any other jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)*<u>Jurisdiction</u>*. By accepting a Stock Award, each Participant will be deemed (a) to have submitted irrevocably and unconditionally to the jurisdiction of the federal and state courts located within the geographic boundaries of the United States District Court for the District of Maryland for the purpose of any suit, action or other proceeding arising out of or based upon the Plan or any Stock Award; (b) to agree not to commence any suit, action or other proceeding arising out of or based upon the Plan or a Stock Award, except in the federal and state courts located within the geographic boundaries of the United States District Court for the District of Maryland; and (c) to have waived and agreed not to assert, by way of motion as a defense or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that the Plan or a Stock Award or the subject matter thereof may not be enforced in or by such court.

**APPENDIX B: NOVAVAX, INC. 2013 STOCK PURCHASE PLAN AMENDED AND RESTATED APRIL 22, 2026**<br>

**NOVAVAX, INC.**

**2013 EMPLOYEE STOCK PURCHASE PLAN**

**AMENDED AND RESTATED APRIL 22, 2026**

**Section 1.Purpose of Plan**

The Novavax, Inc. 2013 Employee Stock Purchase Plan, as amended and restated April 22, 2026 (the "Plan"), is intended to enable eligible employees of Novavax, Inc. (the "Company") and such of its Subsidiaries (including any corporation that becomes a Subsidiary of the Company after the adoption and approval of the Plan) as the Board of Directors of the Company (the "Board") may from time to time designate (the Company and such Subsidiaries being hereinafter referred to as the "Company") to purchase shares of common stock, $0.01 par value, of the Company (such common stock being hereafter referred to as "Stock"), and thereby enhance the sense of participation in the affairs of the Company. For purposes of the Plan, a "Subsidiary" is any corporation that would be treated as a subsidiary of the Company under Section 424(f) of the Internal Revenue Code of 1986, as amended (the "Code"). The Plan is intended to qualify under Code Section 423 and to be exempt from the application and requirements of Code Section 409A, and is to be construed accordingly.

**Section 2.Administration of Plan**

The Plan shall be administered by the Compensation Committee of the Board (the "Committee"), which shall have the authority to determine eligibility under the Plan, to interpret the Plan, to prescribe forms, rules and procedures under the Plan, to adopt, amend, rescind, administer, and interpret such forms, rules and procedures and otherwise to do all things necessary or advisable to carry out the terms of the Plan. To the extent permitted by applicable law, the Committee in its discretion may delegate any or all of its powers under the Plan to one or more officers or employees of the Company. All references in the Plan to the "Administrator" shall mean the Committee and the person or persons so delegated to the extent of such delegation, as applicable. All determinations and decisions by the Administrator regarding the interpretation or application of the Plan shall be final and binding on all parties.

------

**Appendix B**<br>

**Section 3.Options to Purchase Stock**

Subject to adjustment as provided in Section 15, the maximum aggregate number of shares of Stock available for purchase pursuant to the exercise of options ("Options") granted under the Plan to employees of the Company or its designated Subsidiaries ("Employees") who meet the eligibility requirements set forth in Section 4 ("Eligible Employees") shall be the lesser of (a) 3,375,888 shares increased on January 1 of each year by 5% of the share pool on such January 1 (rounded down to the nearest whole share), and (b) 4,820,564 shares.

The Stock to be delivered upon exercise of Options under the Plan may be either shares of authorized but unissued Stock or shares of reacquired Stock, as the Board may determine. If any Option granted under the Plan shall expire or terminate for any reason without having been exercised in full or shall cease for any reason to be exercisable in whole or in part, the unpurchased Stock subject to such Option shall again be available for purchase pursuant to the exercise of Options under the Plan.

**Section 4.Eligibility**

Subject to the limitations set forth in Section 5, each Employee whose customary employment is at least 20 hours per week, whose customary employment is for more than five months during the calendar year and who has been employed by the Company for not less than five business days as of the first day of an Option Period (as defined in Section 5) shall be eligible to participate in the Plan for such Option Period. The Administrator may, for Option Periods that have not yet commenced, establish additional eligibility requirements not inconsistent with Code Section 423.

**Section 5.Option Periods**

Unless otherwise determined by the Board (and except as otherwise provided in Section 8), the "Option Periods" shall be consecutive and overlapping 24-month periods that shall commence every six months on August 1 and February 1 and end 24 months later on July 31 or January 31, with each Option Period having four six-month "Purchase Periods" that shall commence on August 1 or February 1 and end on January 31 or July 31 each year during the Option Period. Each January 31 and July 31 during an Option Period shall be a "Purchase Date". The Administrator may change the frequency and duration of the Option Periods, Purchase Periods and Purchase Dates with respect to Option Periods that have not yet commenced, except as provided in Section 15, in accordance with Code Section 423.

------

**Appendix B**<br>

**Section 6.Participation and Option Grant**

Each person who is an Eligible Employee on the first day of any Option Period may elect to participate in the Plan for such Option Period in accordance with this Section 6, Section 7 and any other procedures established by the Administrator. Except as otherwise provided in Section 8, to become a Participant and enroll in an Option Period, an Eligible Employee must complete an enrollment and payroll deduction authorization form in a form prescribed by the Administrator and submit it to the Company no later than five business days before the first day of each Option Period, or such later time as determined by the Administrator, and shall thereby become a participant ("Participant") on the first day of such Option Period. A Participant may participate in only one Option Period at any time.

Each person who is a Participant on the first day of an Option Period shall automatically be granted on that day an Option for such Option Period entitling the Participant to purchase shares of Stock on each Purchase Date within the Option Period on which the Participant is an Eligible Employee. No more than 25,000 shares may be purchased by a Participant on any Purchase Date, and no more than 15% of a Participant's Compensation at any time may be used to purchase shares of Stock under an Option. A Participant's "Compensation" for any period shall be the sum of the following forms of compensation paid to or earned by a Participant: base wages, salary, overtime, payments for paid time off and holidays, bereavement pay, jury/witness duty pay, pay during a period of suspension, compensation deferred pursuant to Code Sections 401(k) or 125, distributions under any nonqualified deferred compensation plan and any other compensation or remuneration that the Committee or the Board approves as "compensation" in accordance with Code Section 423. Notwithstanding the foregoing:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)No Participant shall be granted an Option under the Plan who, immediately after the Option is granted, would own (or pursuant to Code Section 424(d) would be deemed to own) stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company or of its Subsidiaries; 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;(b)No Participant shall be granted an Option under the Plan that would permit the Participant to accrue rights to purchase shares of stock under all employee stock purchase plans of the Company and its Subsidiaries at a rate that exceeds $25,000 (or such other maximum as may be prescribed from time to time by the Code) for any calendar year, determined using the closing stock price on the grant date, all as determined in accordance with Code Section 423(b)(8).

The Administrator shall reduce, on a substantially proportionate basis, the number of shares of Stock that may be purchased by each Participant for an Option Period or for one or more

------

**Appendix B**<br>

Purchase Periods in the event that the number of shares then available under the Plan is insufficient.

**Section 7.Method of Payment**

Payment for Stock purchased upon the exercise of an Option shall be made with funds withheld through regular payroll deductions. Each payroll deduction authorization shall request withholding for each payroll period at a whole percentage of the Participant's Compensation not exceeding 15% of Participant's Compensation for the payroll period. Withholding shall be accomplished by means of deductions made on payroll dates occurring in the Option Period. A Participant may decrease his or her payroll deduction rate two times during a Purchase Period within an Option Period; provided, however, that the second decrease during any such Purchase Period will reduce the payroll deduction rate to 0%. The payroll deduction rate as decreased by a Participant during a Purchase Period will automatically be applied to the next Purchase Period within the applicable Option Period unless the Participant elects to increase the payroll deduction rate for such next Purchase Period by notifying the Administrator not less than five business days prior to the first day of such Purchase Period. The Administrator may, in its discretion, further limit the number of payroll deduction changes during any Option Period. A change in the payroll deduction rate shall be effective with the first full payroll period following 10 business days after the Company's receipt of the new payroll deduction authorization unless the Company elects to process a given change in payroll deductions more quickly.

All amounts withheld pursuant to this Section 7 (whether by payroll deductions or otherwise) shall be credited to a withholding account maintained in the Participant's name on the books of the Company (each, an "Account"). Amounts credited to the Account shall not be required to be set aside in trust or otherwise segregated from the Company's general assets.

**Section 8.Purchase Price**

The purchase price of Stock issued pursuant to the exercise of an Option on each Purchase Date shall be the lower of 85% of the fair market value of the Stock on the date on which the Option was granted pursuant to Section 5 (i.e., the first day of an Option Period) and 85% of the fair market value of the Stock on the last day of the Purchase Period (i.e., the Purchase Date). For purposes of this Section 8, the fair market value of the Stock for any day shall be the reported closing price of the Stock for such day on the national exchange or trading system on which such shares of Stock are traded; *provided*, that if such day is not a trading day, the fair market value of the Stock on such national exchange or trading system shall be the reported closing price of the Stock for the immediately preceding day that is a trading day.

------

**Appendix B**<br>

If the fair market value of the Stock on any Purchase Date during an Option Period is less than the fair market value of the Stock on the first day of the Option Period, the balance in a Participant's Account shall be applied to purchase Stock on that Purchase Date in accordance with Section 9 and that Option Period shall then terminate. A Participant in the terminated Option Period shall automatically be enrolled in the next Option Period with the Participant's payroll deductions determined by reference to the last payroll deduction authorization properly submitted to the Company in accordance with the Plan.

**Section 9.Exercise of Options**

Subject to the limitations set forth below in this Section 9, each Employee who is a Participant in the Plan on the last day of a Purchase Period shall be deemed to have exercised on such date the Option granted to him or her for the Option Period that includes that Purchase Period. Upon such exercise, the Company shall apply the balance of the Participant's Account to the purchase of the maximum number of whole shares of Stock that can be purchased under the Option with the Account balance at the purchase price determined under Section 8, and as soon as practicable thereafter shall evidence the transfer of shares or shall deliver the shares to the Participant and shall return to the Participant's Account the balance, if any, of his or her Account in excess of the total purchase price of the shares so issued within a reasonable time thereafter. No fractional shares shall be purchased; any payroll deductions accumulated in a Participant's Account that are not sufficient to purchase a full share shall be retained in the Participant's Account for the subsequent Purchase Period, subject to earlier withdrawal by the Participant as provided in Section 12 hereof.

Any amounts contributed by a Participant or withheld from a Participant's Compensation that are not to be used for the purchase of Stock, whether because of such Participant's withdrawal from participation in an Option Period or for any other reason, shall be repaid to the Participant or his or her designated beneficiary or legal representative, as applicable, within a reasonable time thereafter.

Notwithstanding anything herein to the contrary, no Option may be exercised after twenty-seven (27) months from its grant date.

**Section 10.Interest**

No interest shall be payable on any amount held in the Account of any Participant.

**Section 11.Taxes**

Payroll deductions shall be made on an after-tax basis. The Company shall have the right, as a condition of exercise, to make such provision as it deems necessary to satisfy its obligations

------

**Appendix B**<br>

to withhold federal, state and local income or other taxes incurred by reason of the purchase or disposition of Stock under the Plan. The Company in its discretion may, to the extent permitted by law, satisfy its withholding obligations by deduction from any payment of any kind due to the Participant or by withholding shares of Stock purchased under the Plan, which shares shall be valued at fair market value (defined as the closing stock price on the date of withholding).

**Section 12.Cancellation and Withdrawal**

Subject to Section 7, a Participant who holds an Option under the Plan may cancel all of his or her Option and thereby terminate his or her participation in the Plan by written notice delivered to the Administrator. To be effective with respect to the Purchase Period then in progress, written notification of such termination must be submitted to the Administrator no later than 15 days before the last day of the Purchase Period. Upon such cancellation, the balance in the Participant's Account shall be returned to the Participant as soon as administratively practicable.

**Section 13.Termination of Employment; Death of Participant**

Upon the termination of a Participant's employment with the Company for any reason or the death of a Participant during an Option Period, or in the event the Participant ceases to qualify as an Eligible Employee, the Participant shall cease to be a Participant, any Option held by the Participant under the Plan shall be deemed canceled, the balance of his or her Account shall be returned to the Participant (or to the Participant's estate or designated beneficiary in the event of the Participant's death) as soon as reasonably practicable, and the Participant shall have no further rights under the Plan.

**Section 14.Equal Rights; Participant's Rights Not Transferable; Establishment of Sub-Plans**

All Participants granted Options under the Plan shall have the same rights and privileges. Any Option granted under the Plan shall be exercisable during the Participant's lifetime only by the Participant and may not be sold, pledged, assigned, or transferred in any manner. In the event a Participant violates or attempts to violate the terms of this Section, any Options held by the Participant shall be deemed terminated and, upon return to the Participant of the balance of his or her Account, all of the Participant's rights under the Plan shall terminate.

Notwithstanding the foregoing or any provision of the Plan to the contrary, consistent with the requirements of Code Section 423, the Administrator may, in its sole discretion, amend the terms of the Plan, or an offering and/or provide for separate offerings under the Plan in order to, among other things, reflect the impact of local law outside of the United States as applied to

------

**Appendix B**<br>

one or more Eligible Employees of a designated Subsidiary and may, where appropriate, establish one or more sub-plans to reflect such amended provisions.

**Section 15.Change in Capitalization, Merger**

The Board or the Committee may make adjustments in accordance with and as described in this Section 15 in the event of (i) a transaction with the holders of Stock of the Company not involving the receipt by the Company of consideration, including a stock split, spin-off, stock dividend, and certain recapitalizations (such transactions, "Equity Restructurings"), or (ii) the payment of a dividend or other distribution, reorganization, merger, or other changes in corporate structure (such transactions, "Corporate Transactions"). In the event of an Equity Restructuring or, to the extent the Board or the Committee determines that adjustments would be appropriate to prevent dilution or enlargement of benefits under the Plan, a Corporate Transaction, the Board or the Committee shall equitably adjust (a) the class of Stock issuable and the maximum number of shares of Stock available under the Plan, (b) the class and number of shares of Stock and the purchase price per share of Stock with respect to any outstanding Option, and (c) the class and maximum number of shares of Stock that may be issued to a participant during any Purchase Period, *provided*, that no such adjustment may be made unless the Board or the Committee, as applicable, is satisfied that it will not constitute a modification of the rights granted under the Plan or otherwise disqualify the Plan as an employee stock purchase plan under the provisions of Section 423 of the Code.

In the event of (i) a merger or similar transaction in which the Company is not the surviving corporation or that results in the Company's shareholders ceasing to own shares of Stock, (ii) a sale of all or substantially all of the assets of the Company, (iii) an acquisition resulting in ownership of more than 50% of the Stock by any one person (or more than one person acting as a group) that did not own more than 50% of the Stock immediately prior to the acquisition, or (iv) the replacement during any 12-month period of a majority of the directors of the Board by new directors whose appointment was not endorsed by a majority of the directors of the Board prior to the date of the appointment or election, each Option Period then in progress will continue unless otherwise provided by Board or the Committee, which may in its discretion (a) if the Company is merged with or acquired by another corporation, provide that each outstanding Option will be assumed or exchanged for a substitute Option granted by the acquiror or successor corporation, (b) cancel each outstanding Option and return the balances in Participant Accounts to the Participants, or (c) terminate any and all Purchase Periods on or before the date of the proposed transaction. In the event of our proposed dissolution or liquidation, each Option Period then in progress will be cancelled immediately prior to the consummation of such dissolution or liquidation and the balances in Participant's Accounts will be returned to Participants unless Board or the Committee provides otherwise in its sole discretion.

------

**Appendix B**<br>

**Section 16.Amendment and Termination of Plan**

The Board reserves the right at any time or times and for any reason to amend the Plan to any extent and in any manner it may deem advisable, by vote of the Board; except that (a) no amendment may affect an Option Period in progress at the time of the amendment or may adversely affect the rights of any Participant without such Participant's consent unless (i) such amendment is required to satisfy the requirements of Code Section 423, (ii) such amendment is made in connection with a transaction described in Section 15, or (iii) the Board in its discretion determines that the continuation of the Plan on its current terms or any Option Period would result in financial accounting treatment for the Plan that is different from the financial accounting treatment in effect on the date the Plan was initially adopted by the Board, and (b) any amendment that would be treated as the adoption of a new plan for purposes of Code Section 423 and the regulations thereunder shall not take effect unless approved by the shareholders of the Company within twelve months before or after its adoption.

The Plan may be suspended or terminated at any time by the Board. In connection therewith, the Board may provide that outstanding Options shall be exercisable either at the end of the applicable Purchase Period or at such earlier date as the Board may specify (in which case such earlier date shall be treated as the last day of the applicable Purchase Period).

**Section 17.Approvals**

The Plan was approved by the shareholders of the Company on [June 18], 2026, which date was within twelve months after the date the Plan was adopted by the Board.

Notwithstanding anything herein to the contrary, the Company's obligation to issue and deliver shares of Stock under the Plan shall be subject to any required approval of any governmental authority in connection with the authorization, issuance, sale or transfer of said shares, to any requirements of any national securities exchange applicable thereto, and to compliance by the Company with other applicable legal requirements in effect from time to time.

**Section 18.Information Regarding Disqualifying Dispositions**

By electing to participate in the Plan, each Participant agrees to provide such information about any transfer of Stock acquired under the Plan as may be requested by the Company or any Subsidiary in order to assist it in complying with applicable tax laws.

**Section 19.Participants' Rights as Shareholders and Employees**

A Participant shall have no rights or privileges as a shareholder of the Company and shall not receive any dividends in respect of any Stock covered by an Option granted hereunder until

------

**Appendix B**<br>

the Option has been exercised, full payment has been made for the Stock, and the Stock has been issued to the Participant.

Nothing contained in the provisions of the Plan shall be construed as giving to any Employee the right to be retained in the employ of the Company or as interfering with the right of the Company to discharge, promote, demote or otherwise re-assign any Employee from one position to another within the Company at any time.

**Section 20.Governing Law**

&nbsp;&nbsp;&nbsp;&nbsp;The Plan shall be governed by and interpreted in accordance with the laws of the State of Delaware, except as may be necessary to comply with applicable requirements of federal law.

**Section 21.Effective Date and Term**

&nbsp;&nbsp;&nbsp;&nbsp;The Board adopted this Plan, as amended and restated on April 22, 2026. The Plan shall terminate and no rights shall be granted hereunder after April 19, 2034.
