We will continue working to provide strong governance and independent oversight to represent your interests as Emergent builds upon the success of its stabilization efforts and moves toward turnaround and transformation.

The Board is divided into three classes, with one class being elected each year and members of each class serving for staggered three-year terms.

Corporate Governance Guidelines
We are strongly committed to the highest standards of ethical conduct and corporate governance. These standards are consistent with our corporate culture. We understand that adhering to sound principles of corporate governance is critical to earning and maintaining the trust of our customers, employees and stockholders. Accordingly, our Board has adopted corporate governance guidelines to assist in the exercise of its duties and responsibilities and to serve the best interests of the Company and our stockholders. These guidelines, which provide a framework for the conduct of the Board’s business, include the following:
•The Board’s principal responsibility is to oversee the management of the Company;
•A majority of the members of the Board shall be independent directors;
•The independent directors shall meet regularly in executive session;
•Directors shall have full and free access to management and, as necessary and appropriate, independent advisors;
•New directors shall participate in an orientation program and all directors are expected to participate in continuing director education on an ongoing basis;
•At least annually, the Board and its committees will conduct a self-evaluation to determine whether they are functioning effectively; and
•In the interest of the Company and its stockholders, the Board oversees sustainability and corporate responsibility activities.
Copies of our corporate governance guidelines and code of conduct are available on our website at www.emergentbiosolutions.com under “Investors — Governance.”

Board Independence
Under applicable New York Stock Exchange (“NYSE”) rules, a director will qualify as “independent” only if our Board affirmatively determines that such director has no material relationship with us, either directly or as a partner, stockholder or officer of an organization that has a relationship with us. Our Board has established guidelines to assist it in determining whether a director has such a material relationship. Under these guidelines, a director is not considered to have a material relationship with us if our Board determines that such director is independent under Section 303A.02 of the NYSE Listed Company Manual, even if such director:
•Is an executive officer of another company which is indebted to us, or to which we are indebted, unless the total amount of either company’s indebtedness to the other is more than 1% of the total consolidated assets of the company with which such director serves as an executive officer; or
•Serves as an officer, director or trustee of a tax-exempt organization to which we make contributions, unless our discretionary charitable contributions to the organization are more than the greater of $1 million or 2% of that organization’s consolidated gross revenues. Our matching of employee charitable contributions would not be included in the amount of our contributions for this purpose.
In addition, ownership of a significant amount of our stock, by itself (as under NYSE listing standards), does not constitute a material relationship. For relationships not covered by the guidelines set forth above, the determination of whether a material relationship exists is made by the other members of our Board who are independent.
Independence Determinations
Our Board has determined that all of our current directors except Mr. Papa meet the foregoing independence standards, that none of these directors has a material relationship with us and that each of these directors is “independent” as determined under Section 303A.02 of the NYSE Listed Company Manual.
Meetings and Attendance
In 2024, our Board met 7 times and the committees of the Board met 47 times in aggregate. During 2024, no director attended fewer than 75% of the total number of meetings of the Board of Directors and the total number of meetings of the committees of which the director was a member that occurred during the period that such director served.
Our corporate governance guidelines provide that directors are expected to attend the annual meetings of stockholders. All members of our Board at the time of the 2024 annual meeting of stockholders attended the meeting.
The Board’s Role in Risk Oversight
Our Board is actively engaged in the oversight of risks we face and consideration of the appropriate responses to those risks. The Audit and Finance Committee of our Board periodically discusses risk management, including guidelines and policies to govern the process by which our exposure to risk is handled, with our senior management. The Audit and Finance Committee also reviews and comments on a periodic risk assessment performed by management. After the Audit and Finance Committee performs its review and comment function, it reports any significant findings to our Board. The Board is responsible for the oversight of our risk management programs and, in performing this function, receives periodic risk assessment and mitigation initiatives for information and approval as necessary.
The Board’s other committees oversee risks associated with their respective areas of responsibility. For example, the Compensation Committee considers the risks associated with our compensation policies and practices for both executive compensation and compensation generally. In addition, the Audit and Finance Committee assists the Board in the oversight of our financial risk management function. In addition, the Quality, Compliance, Manufacturing and Risk Management Committee assists the Board in fulfilling its oversight responsibilities relating to the Company’s ethics and compliance program, including the Code of Conduct and Business Ethics. The Quality, Compliance, Manufacturing and Risk Management Committee also has oversight of compliance with laws, regulations, and industry standards that, if breached, may cause significant business, regulatory, or reputational damage to the Company, including oversight of the Company’s Enterprise Risk Management program and its cyber and information security risks.

Director Nomination Process
The process followed by our Nominating and Corporate Governance Committee to identify and evaluate director candidates includes requests to members of our Board, management and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by members of the committee and the Board.
In considering whether to recommend any particular candidate for inclusion in the Board’s slate of director nominees, our Nominating and Corporate Governance Committee considers the candidate’s integrity, business acumen, knowledge of our business and industry, experience, diligence, conflicts of interest and the ability to act in the interests of all stockholders, as well as the needs of the Board for a specific skill set or experience. The Nominating and Corporate Governance Committee does not assign specific weights to particular criteria and no particular criterion is a prerequisite for a prospective nominee. The Nominating and Corporate Governance Committee does not have a formal policy with respect to diversity but believes that the backgrounds and qualifications of its directors, considered as a group, should provide a composite mix of experience, knowledge and abilities that will allow it to fulfill its responsibilities. Additionally, as previously noted, our corporate governance guidelines state that it is a goal of the Board to strive for diversity in the composition of the membership of the Board.
Stockholders may recommend to our Nominating and Corporate Governance Committee individuals for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials and a statement as to whether the stockholder or group of stockholders making the recommendation has beneficially owned more than 5% of our common stock for at least a year as of the date such recommendation is made, to the Nominating and Corporate Governance Committee, c/o Corporate Secretary, Emergent BioSolutions Inc., 300 Professional Drive, Gaithersburg, Maryland 20879. Assuming that appropriate biographical and background material has been provided on a timely basis, in accordance with the procedures described under the heading “Additional Matters — Stockholder Proposals for the 2025 Annual Meeting,” the Nominating and Corporate Governance Committee will evaluate candidates recommended by stockholders by following the same process, and applying the same criteria, as it follows for candidates submitted by others.
Skills/Attributes Composition
We believe our directors possess the skills and attributes necessary to meet our current and future business needs. The Board periodically assesses the mix of skills, attributes and experience of the directors.
Core Attributes for all Board Members
•High level of integrity and character;
•Demonstrated track record of success;
•Advanced degree in science or other relevant discipline; and
•A commitment to contribute the time necessary for active involvement.
Below is a summary of the broader skills possessed by our board members, in the areas of finance/accounting and corporate governance as well as specialized industry experience.

| EMERGENT BIOSOLUTIONS INC. |  |  | 2025 Proxy Statement | 7

Corporate Governance |

Finance and Accounting
Financial Experience; Risk Management/Internal Controls; Investment Banking and Mergers and Acquisitions. A significant number of our directors possess financial experience (a critical understanding of accounting and financial reporting). Most of our directors possess experience with risk management/internal controls (for assessing and managing key company risks and their potential impact on compliance, including but not limited to cybersecurity and data control, regulatory compliance and financial risk management). More than half of our directors have indicated possessing skills in investment banking and mergers and acquisitions (the planning of mergers and acquisitions and other strategic opportunities, capital market transactions and debt financing).
Corporate Governance
Governance Oversight and Executive Compensation. All of our directors have corporate governance skills, with vast experience in governance oversight relationships at public companies, including experience with succession planning and building relationships between Board members and senior management and corporate responsibility initiatives. Many have experience as divisional or functional leaders within a complex organization. With respect to executive compensation skills, our directors are experienced in managing a compensation function and/or implementing a program designed to compensate for executive job performance, including knowledge of broad-based performance and incentive planning and measuring.
Specialized Experience
Pharma/Biotech; Medicine/Science; Government (Health, Defense, Intelligence, Security). Most of our directors have experience in healthcare and scientific research and many have diverse backgrounds in the development and licensing of innovative pharmaceutical countermeasures, vaccines and therapeutics. A significant number of our directors held appointed positions in federal, state and international government agencies, providing them with extensive knowledge of government relations and regulatory pathways in highly regulated industries. Our Board includes several members with a background in oversight of government defense mechanisms, public health preparedness and political affairs.
Sales/Marketing/Distribution/International Business. Our Board includes several members with a working knowledge of expansion strategies for product growth, regulatory interfacing, marketing and branding. Their backgrounds involve, among other things, exposure to growth markets and economies outside of the United States, including oversight of interactions with government agencies, global health trends and regulatory pathways of international operations (e.g., tech transfer).
Investor/Public Relations. Nearly all of our directors have experience with investor/public relations, enabling them to recognize the alignment between company strategic decision-making and investor relationships and an understanding of investor perception, stockholder activism and public relations.
Governance Structure
Our Board of Directors is led by an independent Chairman who provides effective oversight of management. Our Board previously determined to separate the positions of chief executive officer and board chairman. Our Board believes that separating these roles aligns the Company with best practices for corporate governance of public companies and accountability to stockholders. The Board also believes that this separation provides a leadership model that clearly distinguishes the roles of the Board of Directors and management. This structure affords our Chairman the time to focus on managing Board operations and effectiveness and other corporate governance matters, including independent Board leadership.
As an independent Chairman, Dr. Harsanyi serves as the presiding director at all executive sessions of our non-management or independent directors, facilitates communications between the President and Chief Executive Officer and other members of the Board, determines the need for special meetings of the Board and consults with the President and Chief Executive Officer on matters relating to corporate governance and Board performance.
In the event the chairman of our Board of Directors is not an independent director, our corporate guidelines provide that a majority of the Board’s independent directors may appoint an independent director, who has been nominated by the Nominating and Corporate Governance Committee, to serve as Lead Director.
Communicating with the Board of Directors
Our Board will give appropriate attention to written communications that are submitted by stockholders and other interested parties and will respond if and as appropriate. The Chairman of the Board, with the assistance of our corporate secretary is primarily responsible for monitoring communications from stockholders and other interested parties and for providing copies or summaries to the other directors as the Chairman of the Board considers appropriate.
Under procedures approved by a majority of our independent directors, communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that the Chairman of the Board considers to be important for the directors to know. In general, communications relating to corporate governance and corporate strategy are more likely to be

8 | 2025 Proxy Statement |  |  | EMERGENT BIOSOLUTIONS INC.

| Corporate Governance

forwarded than communications relating to personal grievances and matters as to which we receive repetitive or duplicative communications.
Stockholders and other interested parties who wish to send communications on any topic to our Board of Directors or independent directors as a group should address such communications to the Board of Directors or Independent Directors, as applicable, c/o Corporate Secretary, Emergent BioSolutions Inc., 300 Professional Drive, Gaithersburg, Maryland 20879. At the direction of the Board, the corporate secretary will review all such correspondence and forward to the Board or independent directors a summary and/or copies of any such correspondence that deals with the functions of the Board or its committees or that he or she otherwise determines requires their attention.
Delinquent Section 16(a) Reports
Section 16(a) of the Exchange Act requires that our executive officers and directors, and holders of more than 10% of our common stock file reports of ownership and changes in ownership with the SEC and provide us with copies of such reports. Subject to certain exceptions, the Company undertakes to file Section 16 reports on behalf of its directors and executive officers, pursuant to a power of attorney granted to certain attorneys-in-fact at the Company. Based solely on the Company’s review of these reports and executive officer and director certifications, the Company believes that all Section 16(a) filing requirements applicable to its directors and executive officers were complied with during fiscal year 2024 except for inadvertent late Form 4 report filed on February 27, 2024 (two days late), by Richard Lindahl of a transaction exempt from liability under Section 16(b) of the Securities Exchange Act of 1934 relating to the determination of a 0% payout of a performance-based restricted stock unit award.

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

Ernst & Young LLP currently serves as our independent registered public accounting firm. After consideration of the firm’s qualifications and past performance, the Audit and Finance Committee has appointed Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2025.
Under NYSE and SEC rules and the Audit and Finance Committee charter, the Audit and Finance Committee is directly responsible for the selection, appointment, compensation and oversight of the Company’s independent registered public accounting firm and is not required to submit this appointment to a vote of the stockholders. Our Board and the Audit and Finance Committee, however, consider the appointment of our independent registered public accounting firm to be an important matter of stockholder concern and are submitting the appointment of Ernst & Young LLP for ratification by our stockholders as a matter of good corporate practice. One or more representatives of Ernst & Young LLP is expected to be present at the virtual annual meeting and will have an opportunity to make a statement and respond to appropriate questions from stockholders. In the event that our stockholders fail to ratify the appointment of Ernst & Young LLP, it will be considered as a direction to the Audit and Finance Committee to consider the appointment of a different firm. Even if the appointment is ratified, the Audit and Finance Committee in its discretion may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.
Vote Required
Ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm requires the affirmative vote of the majority of votes properly cast on such matter at the annual meeting. Abstentions will have no effect on the outcome of this vote.

PROPOSAL 3 — ADVISORY VOTE TO APPROVE 2024 COMPENSATION OF NEOS

Our Board has determined to provide our stockholders the opportunity to vote each year to approve, on an advisory basis, the compensation of our NEOs as disclosed in this proxy statement.
Our executive compensation programs are designed to attract, motivate, and retain executive officers, who are critical to our success. Under these programs, our NEOs are rewarded for the achievement of our near-term and longer-term financial and strategic goals and for driving corporate financial performance and stability. The programs contain elements of cash and equity-based compensation and are designed to align the interests of our executives with those of our stockholders.
The “Executive Compensation” section, including “Compensation Discussion and Analysis,” each beginning on page 28, describes in detail our executive compensation programs and the decisions made by the Compensation Committee and the Board with respect to 2024. Highlights of our executive compensation program include the following:
1.Pay should be linked to performance;
2.Compensation opportunities should be competitive with relevant peer companies;
3.The equity compensation program should align executive interests with those of stockholders; and
4.Supplemental benefits and perquisites should be limited and used selectively in specific circumstances to attract and retain executives.
As we describe in the “Compensation Discussion and Analysis” section of this proxy statement, our executive compensation program embodies a pay-for-performance philosophy that supports our business strategy and aligns the interests of our executives with those of our stockholders. Our Board believes this link between compensation and the achievement of our near- and long-term business goals has helped drive our performance over time. At the same time, we believe our program does not encourage excessive risk-taking by management and that our compensation policies and practices are not reasonably likely to have a material adverse effect on us.
Pursuant to Section 14A of the Exchange Act, our Board is asking stockholders to approve, on an advisory basis, the following resolution:
RESOLVED, that the compensation paid to Emergent BioSolutions Inc.’s named executive officers in 2024, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the compensation discussion and analysis, the compensation tables and any related narrative discussions disclosed in this proxy statement, is hereby approved on an advisory basis.
As an advisory vote, this proposal is not binding. Although the vote is non-binding, our Compensation Committee and Board value the opinions expressed by our stockholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for our executive officers.
Vote Required
Approval of the advisory vote on NEO compensation for 2024 requires the affirmative vote of the majority of the votes properly cast on the matter at the annual meeting. Abstentions and broker non-votes will have no effect on the outcome of this vote.

| The Board of Directors recommends a vote “FOR” the approval, on an advisory basis, of the 2024 compensation of our named executive officers. |

2024 Say-on-Pay

At our 2024 annual meeting of stockholders, over 97% of votes from our stockholder were cast in favor of our say-on-pay resolution confirming continued support for our executive compensation framework. A positive and supportive indication of our governance practices and our compensation program. |  |  | 97% votes in favor |

Alignment of Pay with Performance
These achievements exceeded the expectations we had at the start of 2024. Reflecting our commitment to designing executive compensation programs that align pay and performance, this resulted in the following:
•Above target outcomes for annual cash incentive awards. Our corporate performance factor yielded results above target, which would have resulted in a 130% payout for the year. Upon evaluating the outstanding accomplishments in 2024, the Compensation Committee approved a 140% payout for the year. As discussed in the following section, executive officers were ineligible for awards under the Company’s 2023 Annual Bonus Plan following the approval of a Key Employee Retention Plan (“KERP”) that was implemented in July 2023. The final payments from this plan were made in 2024.
•2022-2024 PSUs were forfeited due to not achieving the threshold performance goals. The performance stock unit (PSU) awards granted in 2022 concluded their three-year performance period on December 31, 2024. The three-year cumulative adjusted EBITDA margin for the performance period as presented to and determined by the Compensation Committee on February 14, 2025 to be 6.2%, resulting in a 2022 PSU payout factor of 0% of target.
•Outstanding equity is valued below threshold. Reflecting our stock price at the end of 2024, recent equity awards have an economic value substantially lower than their grant date fair value, and some historical stock option awards are underwater with no intrinsic value. The pay versus performance disclosure beginning on page 57 of this proxy statement further illustrates the declining equity values over the past five years and the impact this has had on “compensation actually paid,” as defined in SEC rules relating to our pay versus performance disclosures.
2024 Compensation at a Glance
The Compensation Committee approves the target compensation levels, mix and design for our executive officers. Our executive compensation program in 2024 was modified from the prior year and was comprised of base salary, target annual cash incentive, and a fixed share annual equity grant solely in stock options. The Compensation Committee approved the compensation program for our executive officers, other than Mr. Papa, effective January 1, 2024.
CEO Compensation
Effective February 21, 2024, the Company announced that Mr. Papa had been appointed as President, CEO and Director succeeding Mr. Miller who had served as Interim CEO since June 24, 2023. In connection with Mr. Papa’s appointment, the Compensation Committee approved the following compensation:
•Base salary. Mr. Papa’s annual base salary was set at $1,000,000.
•Annual incentive for 2024 performance. Mr. Papa’s annual cash incentive was set at 130% target, which aligns with the target annual cash incentive set forth his employment agreement, please see “CEO Employment Agreement” beginning on page 55.
•Equity and performance grants in 2024. In connection with his hiring, Mr. Papa received the equity and performance grants as set forth in his employment agreement, please see “CEO Employment Agreement” beginning on page 55.
Former CEO Compensation
Haywood Miller, who had been an advisor to the Company since April 2023, was announced as Interim CEO effective June 24, 2023. The Compensation Committee approved payment of monthly cash compensation in the value of $125,000 to Mr. Miller until the earlier of the appointment of a permanent CEO and June 24, 2024. Mr. Miller did not receive any other compensation in connection with his role. Mr. Miller ceased to serve as Interim CEO effective February 21, 2024, following the appointment of Mr. Papa.

| Executive Compensation

Other NEO Compensation
For 2024, the Compensation Committee approved the following compensation program for NEOs, other than Mr. Papa:
•Limited increases to base salaries. Executive officers received salary increases for 2024, which ranged from approximately 4 - 5%.
•Annual cash incentive opportunities with weighting of financial measures increased. Payouts were earned based on a combination of corporate, which increased the financial performance measure, and individual performance goals weighted 90% and 10%, respectively. Corporate performance reflected a combination of financial and operational priorities for the year, along with an increased weighting of financial goals to formally account for equal to or greater than 50% overall corporate performance factor. Otherwise, there were no changes to NEOs’ annual cash incentive opportunities for 2024, other than a 10% increase to target cash incentive for Messrs. WIlliams and Hartzel.
•Annual equity awards granted solely in stock options. The usage of fixed stock option shares allowed us to minimize the usage of our share pool leaving an adequate reserve for strategic hires and promotions. Also, due to the risks of setting multi-year performance goals during a period of significant transformation, the Compensation Committee determined that executive equity awards for 2024 would be granted in stock options. Awards were approved as a consistent fixed share amount that vest over a three-year period subject to continued service, with one-third of the total grant vesting on the day prior to each of the 1 st, 2 nd and 3 rd annual anniversaries of the date of grant. The 2024 option grants will expire immediately prior to the 7 th annual anniversary of the date of grant.
Looking to 2025
CEO Compensation
The Compensation Committee approved the compensation for Mr. Papa, effective January 1, 2025, as follows:
•Increase to base salary. Based on its evaluation of Mr. Papa’s 2024 performance, the Compensation Committee increased Mr. Papa’s base salary from $1,000,000 to $1,040,000, a 4% increase.
•2024 annual cash incentive. Based on its evaluation of corporate performance as indicated by the corporate factor, the Compensation Committee determined to award Mr. Papa a cash bonus of $1,566,474 for his contributions to the Company’s performance in 2024, which was 140% of his 2024 annual cash incentive target opportunity, prorated for his February 21, 2024 hire date.
•Annual equity award granted in 50% stock option and 50% PSU’s. An equity award consisting of 282,500 stock options and 282,500 Performance stock units (PSUs) were approved and granted on March 6, 2025. The stock options will vest over a three-year period subject to continued service, with one-third of the total grant vesting on the day prior to each of the 1 st, 2 nd and 3 rd annual anniversaries of the date of grant. The PSU will vest over a three-year period subject to continued service, subject to the attainment of certain adjusted EBITDA targets for 2025.
Other NEO Compensation
For 2025, the modest changes approved by the Compensation Committee for NEOs, other than Mr. Papa, are summarized below:
•Limited increases to base salaries. Executive officers received salary increases for 2025, which ranged from approximately 3.5 - 3.75%.
•Unchanged annual cash incentive opportunities with unchanged weighting of financial measures. There were no changes to the annual cash incentive opportunities for 2025. Payouts will continue to be earned based on a combination of corporate and individual performance goals weighted 90% and 10%, respectively. Corporate performance will continue to reflect a combination of financial and operational priorities for the year, with the continued weighting of financial goals to formally account for equal to or greater than 50% of the overall corporate performance factor.
•Annual equity awards in the form of 50% stock options and 50% RSUs. The annual equity awards will vest over a three-year period subject to continued service, with one-third of the total grant vesting on the day prior to each of the 1 st, 2 nd and 3 rd annual anniversaries of the date of grant. The 2025 option grants will expire the day immediately prior to the 7 th annual anniversary of the date of grant.
The Compensation Committee made these decisions holistically with due consideration of multiple factors and focused on the best interests of our stockholders. Our compensation program continues to emphasize equity-based compensation and pay-for-performance.

COMPENSATION GOVERNANCE

Executive Compensation Processes
The Compensation Committee has implemented an annual review program for our executive officers under which it determines annual salary increases, annual cash bonus amounts and annual equity awards granted to our executive officers. Our chief executive officer and chief human resources officer prepare compensation recommendations regarding the compensation of each of the executive leadership team, which includes all of our executive officers and certain other senior officers of the Company, other than the chief executive officer, and present these recommendations to the Compensation Committee for approval. The Compensation Committee evaluates the overall performance of the chief executive officer and the other executive officers based on achievement of corporate goals and objectives, achievement of individual goals, performance of job responsibilities and demonstration of behavioral competencies. The Compensation Committee then makes individual compensation decisions for the chief executive officer and the executive officers based on these evaluations and competitive market data.
Our chief executive officer, chief financial officer and chief human resources officer have the authority to grant stock options and RSUs to employees under the Emergent BioSolutions Inc. Amended and Restated Stock Incentive Plan. However, neither our chief executive officer nor any other officer has authority to grant stock options or RSUs: (i) to himself or herself; (ii) to any other director, executive officer, officer or other person whose compensation is determined by the Compensation Committee; or (iii) to any person whom the Board or the Compensation Committee may from time to time designate in writing.
Role of the Compensation Committee
The primary purpose of the Compensation Committee is to oversee the discharge of the responsibilities of the Board relating to compensation of the Company’s executive officers, and comprises four independent directors, chaired by Dr. Sullivan.
The core duties of the Compensation Committee include:
•Evaluating the performance of and determining compensation for the CEO.
•Evaluating the performance of other executive officers.
•Reviewing compensation recommendations prepared by the CEO and chief human resources officer for other executive officers.
•Overseeing our incentive plans, including approving performance goals and objectives applicable to executive officers, and the Company’s employee stock purchase plan.
•Reviewing and discussing this Compensation Discussion and Analysis of executive compensation and the Compensation Committee Report.
•Overseeing compensation risk management.
•Staying abreast of emerging market trends and regulatory/legislative developments and evaluating the potential impact on broader compensation policies/programs, as appropriate.
Role of Advisors
The Compensation Committee has the authority to retain compensation consultants and other outside advisors to assist in the evaluation of executive officer compensation. During 2024, the Compensation Committee retained WTW (formerly known as Willis Towers Watson) as an independent outside compensation consultant, which has been WTW’s role with the Compensation Committee for the last several years. In this capacity, WTW was invited to provide advice on market compensation practices, programs, and policies; provide competitive compensation data; review compensation-related recommendations from management; and assist with the implementation of various compensation decisions. Furthermore, WTW, frequently meets with management to gain input on objectives with respect to executive compensation in order to assist the Compensation Committee in its deliberations.
The Compensation Committee reviews independence annually, in accordance with SEC requirements, to understand any relationships between WTW and Emergent. Following an assessment in 2024, the Compensation Committee determined that WTW’s work had not raised a conflict of interest and that WTW is an independent compensation advisor to the Compensation Committee and the Company.

Stockholder Engagement
Our Board and Compensation Committee recognize the importance of receiving regular input from our stockholders on important issues, including our executive compensation program. Our annual non-binding advisory vote on executive compensation provides an opportunity for all of our stockholders to have a regular say-on-pay, the results of which are considered by the Compensation Committee. Consistent with prior years, we received high levels of support with over 97% of votes cast in favor of our 2024 say-on-pay resolution. The Compensation Committee considered this outcome a positive reinforcement of our framework in light of a challenging operating environment, which informed discussions on our 2025 executive compensation framework, which remains largely unchanged.
Use of Market Data

The Compensation Committee reviews compensation levels and program design at comparable companies as part of its decision-making process so it can set total compensation levels that it believes are competitive and aligned with performance. Several peer groups are utilized to ensure high quality, relevant and reliable competitive market data that supports informed decision-making. The compensation committee generally sets NEO target total direct Compensation to be Competitive within this context, taking into consideration the scope of job responsibilities, individual performance, experience, internal pay equity and other relevant factors. |  |  |  |

Five new companies were added in 2024 to improve Emergent’s comparability with the peer group median, and two companies were removed, in one case to outsized revenues and in the other because the company was acquired and de-listed. The Compensation Committee determined that the 2024 additions combined with the remaining 15 companies provided a sufficiently robust and relevant group to reference. The following companies were included in the Proxy Peer Group to inform 2024 compensation decisions.

Compensation and Risk
The Company maintains a number of policies intended to reflect our compensation philosophy. The key terms of these policies are summarized below.
Stock Ownership Requirements
We continue to believe it is important for directors and executives to have an equity stake in our company to help align their interests with those of our stockholders. Stock ownership guidelines are periodically reviewed and were last increased in 2020.

| Minimum Executive Guidelines | •Chief Executive Officer: Five times base salary(1) •Other Executive Officers: Two times base salary
| Minimum Board Member Guidelines | •Five times Board annual retainer fees(2)
| Period to Comply | •Five years from becoming a covered person under the policy
| Counted Equity Interests | •Stock owned outright by the officer or director •Unvested and vested RSUs and vested PSUs •Stock options are not counted as equity interests
| Retention Requirement | •Retention of 50% of the after-tax shares received upon the vesting of RSUs and PSUs or exercise of stock options until the time the applicable minimum guideline is met

1.Only applies if the Chief Executive Officer is also a member of the Board of Directors.
2.Annual retainer fees exclude meeting fees, committee retainers, committee chair retainers and lead independent director retainers (if applicable).
The Board regularly monitors ownership levels to ensure executives and directors have strong ties to stockholder value, long-term company performance, etc. For 2024, all directors and executives were in compliance with the stock ownership policy.
Compensation Recovery Policy
We have an executive compensation recovery policy that is intended to encourage sound risk management and drive individual accountability, reflecting our commitment to leadership values as part of our compensation philosophy. The Board adopted a revised executive compensation recovery policy (the “Policy”) in October 2023 which complied with NYSE listing standards, a copy of which was filed as Exhibit 97.1 to the Form 10-K filed for the fiscal year ended December 31, 2024. Capitalized terms in this section “Compensation Recovery Policy” that are not otherwise defined have the meanings set forth in the Policy.
The Policy provides that in the event the Company is required to prepare an Accounting Restatement, any Executive Officer who received excess compensation during the lookback period will be required to repay or forfeit any such Excess Compensation reasonably promptly. Recovery of erroneously received compensation under the Policy is on a “no fault” basis, meaning that it will occur regardless of whether the Executive Officer engaged in misconduct or was otherwise directly or indirectly responsible, in whole or in part, for the Accounting Restatement.

| EMERGENT BIOSOLUTIONS INC. |  |  | 2025 Proxy Statement | 37

Executive Compensation |

| Covered Employees | •An individual who is, or was during an applicable Look-back Period, an Executive Officer pursuant to Rule 10D-1(d) of the Exchange Act.
| Covered Compensation | •Incentive-Based Compensation previously awarded up to three completed fiscal years preceding the date on which the Board determines that reimbursement is required. •Incentive-Based Compensation means “[a]ny compensation that is granted, earned or vested based wholly or in part on stock price, total shareholder return, and/or the attainment of (i) any financial reporting measure(s) that are determined and presented in accordance with the accounting principles used in preparing the company’s financial statements and/or (ii) any other measures that are derived in whole or in part from such measures. •This can include: (i) bonus, equity awards or incentive compensation previously awarded; (ii) unvested, restricted, or deferred equity awards previously granted; (iii) profits realized on the sale of certain securities; and (iv) any other compensation covered by Section 304 of the Sarbanes-Oxley Act.
| Covered Events | •“Accounting Restatements,” which means any accounting restatement due to the material noncompliance of the company with any financial reporting requirement.
| Board Authority | •Administering the Policy, including seeking to recoup Excess Compensation in the case of an Accounting Restatement and determining the means of such recoupment.

The Policy provides that the Board will seek to recover excess compensation by all legal means available, including, but not limited to, by requiring any affected executive officer to repay to the Company in a lump sum or over time, by set-off, by cancelling outstanding awards, by reducing future compensation of the affected executive officer, or by such other means or combination of means as the Board, in its sole discretion, determines to be appropriate. In accordance with the Board’s direction, the Company shall take all actions reasonable and appropriate to recover any excess compensation from any applicable Executive Officer, and such Executive Officer shall be required to reimburse the Company for any and all expenses reasonably incurred (including legal fees) by the Company in recovering such excess compensation in accordance with the Policy.
Notwithstanding the above, the Board also may determine that repayment of excess compensation (or a portion thereof) is not required only where it determines that recovery would be impracticable and (i) the direct expense paid to a third party to assist in enforcing this Policy would exceed the amount to be recovered, provided the Company has (A) made a reasonable attempt to recover such excess compensation, (B) documented such reasonable attempt, and (C) provided such documentation to the NYSE, or (ii) recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees, to fail to meet the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and the regulations thereunder.
In addition, the Policy clarifies that forfeiture or recoupment thereunder is in addition to any other remedy available by law or available company policy.
Insider Trading Policy
Our Insider Trading Policy prohibits our directors and executive officers from entering into derivative transactions such as puts, calls, or short sales of our common stock (commonly referred to as hedging), among many other actions. Advance approval is required by the General Counsel if any director or executive officer wishes to pledge Emergent securities or hold Emergent securities in a margin account. We provide training and distribute periodic reminders to our directors and executive officers regarding this policy.
A copy of the Insider Trading Policy is filed as Exhibit 19 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

| Jennifer Fox | 60% | 90% | 10% |

1.As Interim CEO, Mr. Miller was not eligible for a 2024 Target Cash Incentive.
Key Employee Retention Plan
In 2023, the Committee worked with its independent compensation consultant and outside counsel to implement a Key Employee Retention Plan (the “KERP”). The intent of the KERP was to retain critical members of the executive team during a period of continued uncertainty while the Board undertook a search for a new CEO. In approving the KERP, the Compensation Committee considered practices among companies that have deployed in comparable situations. In summary the KERP provided for the following:
•Executive cash retention payments worth 130% of salary. The award was split into two installments: 50% was paid on approval in July 2023 with a 12-month repayment clause; the remaining 50% was paid on the first anniversary of the Compensation Committee’s approval of the KERP in July 2024 (the “Original KERP”). In conjunction with approving the awards, the Compensation Committee determined that executives would not be eligible to receive any annual cash incentive in 2024 relating to 2023 performance.
•Enhanced severance benefits on a change in control, for a period of one year. The Senior Management Severance Plan provisions were reviewed and updated during the one-year critical retention period. The only change was to the cash severance multiple on a change in control, which was increased from 0.75 - 1.5 times base plus target bonus to 1.0 - 2.5-times, varying by level. In July 2024, the severance multiples reverted to their prior values.
•Executive officers were ineligible to participate in the annual cash incentive plan in respect of 2023 performance.
6-Month Extension of KERP
In March 2024, the KERP was extended for a six-month period, which resulted in an additional installment equal to 50% of the award (the “Extended KERP”). Following the payment of the additional installment, the KERP expired.
The following table summarizes the aggregate KERP incentive amounts paid to each eligible NEO in 2024 pursuant to the Original KERP and the Extended KERP:

| Role(1) | Original KERP Incentive(2) ($) | Extended KERP Incentive(3) ($) |
| Joseph Papa(4) | N/A | N/A |
| Richard Lindahl | 399,753 |  | 399,753 |  |
| Coleen Glessner | 373,761 |  | 373,761 |  |
| Paul Williams | 291,500 |  | 291,500 |  |
| William Hartzel | 292,500 |  | 292,500 |  |
| Jennifer Fox | 380,250 |  | — |  |

1.Mr. Miller was ineligible for bonus or retention awards, including the KERP.

4.Mr. Papa was hired on February 21, 2024 and did not participate in the Original KERP or the Extended KERP.

| Executive Compensation

Executive Compensation
The Compensation Committee met in the first quarter of 2025 to assess corporate and individual performance in order to provide executives with feedback regarding 2024 performance. Like other companies in our industry, rather than adopting a formulaic scorecard, judgement is applied in assessing performance against a number of objectives with reference to (i) annual corporate goals, (ii) the corporate operating plan goals and (iii) other general considerations. Performance is assessed against each objective and a rating is assigned indicating the extent to which goals were or were not met. The Compensation Committee can then apply judgement, taking into account broader performance considerations in determining a final corporate factor.
The following table summarizes the outcome in respect of 2024 corporate performance.

| Corporate Objective | Not Met | Meets Expectations | Significantly Exceeds |
| Strengthen financial profile to achieve cost efficiencies and improve business performance. |  |  | ● |
| Execute core business to protect and support public health preparedness. |  | ● |  |
| Deliver near-term organic growth and create longer-term growth opportunities. |  | ● |  |
| Engage our people and evolve our culture in alignment with our business needs and strategy. |  | ● |  |
| Continue to build confidence and trust through sustained quality and compliance. |  | ● |  |
| Corporate Performance Score Payout (eligible employees) |  |  | 140% |

Equity Incentives
Equity incentives represent the largest proportion of an NEOs’ target compensation, other than for Mr. Miller who was not eligible for equity-based compensation in his capacity as Interim CEO. The Compensation Committee considers survey data and peer proxy data, as applicable with reference to market median, but actual grants may be positioned above or below based on any number of factors, including role scope and criticality, individual performance, internal equity and broader market dynamics. The Compensation Committee reviews all components of each executive’s compensation when determining equity awards to ensure that an executive’s total compensation conforms to our overall philosophy and objectives. The Compensation Committee may also consider the value of previously granted equity awards although this, or existing levels of ownership, will not necessarily cause the Compensation Committee to forego making, or reducing the amount of, any future award.
Equity compensation serves a distinct purpose with respect to our compensation philosophy and principles, as summarized below.

| Equity Type and Weighting | Purpose | Key Features
| Stock Options (100%) | •Align executives’ interests with the long-term interests of our stockholders; and •Reward for increases in stock price above the exercise price. | •Exercise price equal to the fair market value of our common stock on the date of grant (defined as the closing sales price of our common stock on the NYSE on the trading day immediately preceding the date of grant); •Seven-year term; and •Vest in three equal annual installments beginning on the day prior to the one-year anniversary of the date of grant.

We generally make an equity grant in the month following the hire date for new executives and in the month following the date of executive promotions. If circumstances warrant, we also may make equity grants at various other points throughout the year. The Compensation Committee approved all awards to executive officers in 2024.
In 2024, the Compensation Committee determined that equity grants for the year would be made in a fixed share option grant due to share pool constraints. Grant date fair values are calculated utilizing a Black Scholes valuation model for stock option awards. This approach meant that grant date fair values were lower than the values approved by the Compensation Committee as a result of the share price decreasing between the date of approval and the date of grant.

| EMERGENT BIOSOLUTIONS INC. |  |  | 2025 Proxy Statement | 41

The Compensation Committee approved the following 2024 annual equity awards.

| William Hartzel | 125,000 | $187,175 |  |
| Jennifer Fox(4) | 125,000 | $187,175 |  |

1.As Interim CEO, Mr. Miller was not eligible for equity incentive awards.
2.Represents underlying shares for 2024 annual equity incentive award, which is based on a fixed amount of shares, granted as stock options.
3.Mr. Papa was not eligible for 2024 equity incentive awards. See “CEO Employment Agreement” beginning on page 55 of this proxy statement for details regarding equity awards made to Mr. Papa in connection with his joining the Company on February 21, 2024.
4.In connection with Ms. Fox’s termination, all stock options awarded in 2024 were forfeited.
2022-2024 Performance Stock Units (PSUs)
Since 2017, the Compensation Committee has utilized PSUs as a means to further align executives’ long-term interests with those of our stockholders, and link pay to multi-year performance objectives of strategic importance. For awards granted between 2020 and 2022, performance goals have been based on a 3-year cumulative adjusted EBITDA as a percentage of GAAP revenue, reflecting our focus on adjusted EBITDA performance as a key profitability metric. Prior to that, performance was based on final year adjusted net income as a percentage of GAAP revenue.
The table below discloses the potential range of performance objective targets under the 2022 PSUs (Threshold, Target and Maximum), the final level of achievement and the ultimate payout factor. Given cumulative adjusted EBITDA margin results fell below the threshold level, none of the PSU awards were vested in early 2024.

| Performance Ranges and Final Outcome Under 2022 PSUs |
| Performance Measure | Performance Objective Targets | Final Level of Achievement(1) | Final 2022 PSU Payout Factor |
| Threshold (50% Vests) | Target (100% Vests) | Maximum (150% Vests) |
| Adjusted EBITDA Margin | 20.5% | 23.5% | 26.5% | 6.2% | 0% |

1.The three-year cumulative adjusted EBITDA margin for the performance period as presented to and determined by the Compensation Committee on February 14, 2025 to be 6.2%.
In addition, the table below reports the original number of shares granted under the 2022 PSUs as well as the number of pre-tax shares actually issued based upon the final level of achievement of adjusted EBITDA margin.

| Role | Number of PSUs Originally Granted (Target) | Number of Shares Issued (Pre-Tax) |
| Richard Lindahl | 16,916 | 0 |

Benefits
We maintain broad-based benefit arrangements that are generally available to all employees as summarized below.

| Benefit | Eligible | Key Features
| Health & Welfare Insurance Benefits | All employees | •Executives are eligible to participate on the same basis as other employees. •Includes health insurance, life and disability insurance and dental insurance.
| 401(k) Plan | All employees | •Executives are eligible to participate on the same basis as other employees. •Matching contribution of 50% of elective deferrals for the year, up to 6% of the participant’s eligible compensation, subject to IRS limitations. •Matching contribution is fully and immediately vested.

Severance and Change in Control
We provide severance and change in control arrangements to select employees, including our NEOs, which are reflected in our Senior Management Severance Plan, effective on July 16, 2015. The plan provides for payments and benefits as a result of involuntary termination without cause or termination of employment in particular circumstances in connection with a change in control. The purpose is to ensure ongoing retention of key executives when considering potential transactions that may create uncertainty as to their future employment.
Severance payments are expressed as a multiple of base salary and target bonus. Multiples range from 1.25 to 2.00 depending on an executive’s role and increase to 2.00 or 2.50 for a termination on a change in control. Other entitlements are also stipulated, including payment of unpaid base salary, earned but unpaid annual bonus, accrued paid time-off and a pro-rata target annual bonus for the year of termination. There are also provisions related to benefits continuation and equity treatment. Detailed information can be found in the “Executive Compensation – Payments Upon Termination or Change in Control” section of this proxy statement.
ADDITIONAL INFORMATION

Tax and Accounting Considerations
Sections 280G and 4999 of the Internal Revenue Code of 1986, as amended (the “Code”) impose certain adverse tax consequences on compensation treated as excess parachute payments. An executive is treated as having received excess parachute payments if such executive receives compensatory payments or benefits that are contingent on a change in control, and the aggregate amount of such payments and benefits equals or exceeds three times the executive’s base amount (which is generally such executive’s average compensation from us over the five years prior to the change in control). The portion of the payments and benefits in excess of one-times base amount is treated as excess parachute payments and are subject to a 20% excise tax, in addition to any applicable federal income and employment taxes. Also, our compensation deduction in respect of the executive’s excess parachute payments is disallowed. If we were to undergo a change in control, certain amounts received by our executives (for example, certain severance payments and amounts attributable to the accelerated vesting of stock options, RSUs and PSUs) could be excess parachute payments under Sections 280G and 4999 of the Code. As discussed below under “Payments Upon Termination or Change in Control” of this proxy statement, we do not provide executive officers with tax gross up payments in the event that Sections 280G and 4999 apply to their compensatory payments.

Payments Upon Termination or Change in Control
Senior Management Severance Plan
Our Compensation Committee adopted the Second Amended and Restated Senior Management Severance Plan (the “Senior Management Severance Plan”), which replaced our Amended and Restated Senior Management Severance Plan. The Senior Management Severance Plan was put into place for the benefit of employees with the title of executive chair, chief executive officer, president, executive vice president, senior vice president or vice president who have been designated to participate in the Senior Management Severance Plan by our Board or, with the authorization of our Board, by our chief executive officer. Our chief executive officer is authorized to designate the greater of 7% of the total number of our employees or 35 employees to be participants in the Senior Management Severance Plan at any particular time, on the basis of name, title, function or compensation level. Our chief executive officer will at all times be a participant under the Senior Management Severance Plan and will have no less favorable rights under the Senior Management Severance Plan than any other participant. Each of the NEOs is currently a participant in the Senior Management Severance Plan.
For-cause terminations. If we terminate a participant’s employment with cause, as defined in the Senior Management Severance Plan, then the participant will not be entitled to receive any compensation, benefits or rights under the Senior Management Severance Plan, and any stock options or other equity participation benefits vested on or prior to the date of the termination, but not yet exercised, will immediately terminate.
Without-cause terminations. If we terminate a participant’s employment without cause, as defined in the Senior Management Severance Plan, the participant will be entitled to:
•Any unpaid base salary and accrued paid time-off through the date of termination;
•A pro-rata portion of the participant’s target annual bonus in respect of the year of termination;
•Any bonus earned but unpaid as of the date of termination for any previously completed year;
•Reimbursement for any unreimbursed expenses incurred by the participant prior to the date of termination;
•An amount equal to a specified percentage of the participant’s annual base salary and target bonus, as indicated in the table below;
•Employee and fringe benefits and perquisites, if any, to which the participant may be entitled as of the date of termination under our relevant plans, policies and programs; and
•Continued eligibility for the participant and his or her eligible dependents to receive employee benefits (such as medical, dental, life insurance (not to exceed one year), and pension benefits), for a stated period following the participant’s date of termination as indicated in the table below, except when the provision of employee benefits would result in a duplication of benefits provided by any subsequent employer.
The following table sets forth the percentage of base salary and the stated period for continued employee benefits to which each of our NEOs was entitled to receive had we terminated the executive officer’s employment without cause on December 31, 2024. Ms. Fox voluntarily terminated from the Company on August 16, 2024, as such she did not receive any payments pursuant to the Senior Management Severance Plan or any other arrangement in connection with her separation from the Company.

If the resulting value of accelerated vesting of stock options was $0.00 or less, no value was attributed. If vesting of stock option is subject to attaining a stock price hurdle, only those stock options for which the applicable stock price hurdle was achieved on or before December 31, 2024 was accelerated and valued.

The value of accelerated vesting of PSUs was calculated by multiplying the number of shares subject to accelerated vesting under PSU grants by $9.56, which was the closing market price per share of our common stock on December 31, 2024, with an associated performance factor of 100%.
General provisions. All payments under the Senior Management Severance Plan will be reduced by any applicable taxes required by law to be paid or withheld by us. If at the time a participant’s employment is terminated, the participant is a “specified employee” within the meaning of Section 409A of the Internal Revenue Code (“Section 409A”), then any payments to the participant that constitute non-qualified deferred compensation within the meaning of Section 409A will be delayed by a period of six months. All such payments that would have been made to the participant during the six-month period will be made in a lump sum on the date that is six months and one day following the date of termination, and all remaining payments will commence in the seventh month following the date of termination. Our Board or any committee thereof designated by our Board is authorized to administer the Senior Management Severance Plan and has authority to adopt, amend and repeal the administrative rules, guidelines and practices relating to the Senior Management Severance Plan as it deems advisable.

Employment Agreements
During fiscal year 2024, none of our NEOs, other than Mr. Papa, had an employment agreement with us. On February 19, 2024, the Company and Mr. Papa entered into a written executive employment agreement concerning Mr. Papa’s employment (the “CEO Employment Agreement”), which is described below under “CEO Employment Agreement.” On an annual basis, the Compensation Committee determines salary increases, cash bonus amounts and equity awards for our NEOs. In addition, the Compensation Committee determines target annual cash bonuses as a percentage of each NEO’s annual base salary. We do not have any formal or informal policy for the amount of executive salary and bonus in proportion to total compensation.
Notwithstanding the above, the Board engaged Haywood Miller of Berkley Research Group (“BRG”) to serve as the Company’s Interim CEO from June 24, 2023 to February 21, 2024. As compensation for Mr. Miller’s professional services as Interim CEO, BRG received monthly cash compensation of $125,000 (or prorated portion thereof) in addition to the reimbursement of reasonable and documented direct out-of-pocket expenses related to Mr. Miller’s provision of services consistent with the Company’s travel and reimbursement policies.

Inducement Plan (the “Inducement Plan”), which will vest upon achievement of certain stock price hurdles ($5, $10 and $15 per share), provided that in no event will vesting occur prior to the first anniversary of the grant date. Mr. Papa also received options under the Inducement Plan to purchase 250,000 shares of the Company’s common stock, which will vest in equal installments over three years, subject to Mr. Papa’s continued service through each vesting date. Mr. Papa also received stock options to purchase up to 500,000 shares of common stock under the Emergent BioSolutions Inc.

Policies and Procedures for
Related Person Transactions
Our Board has adopted written policies and procedures for the review of any transaction, arrangement or relationship in which we are a participant, when the amount involved exceeds $120,000 and one of our executive officers, directors, director nominees or 5% stockholders (or their immediate family members), each of whom we refer to as a related person, has a direct or indirect material interest.
If a related person proposes to enter into such a transaction, arrangement or relationship, which we refer to as a related person transaction, the related person must report the proposed related person transaction to our general counsel. The policy calls for the proposed related person transaction to be reviewed and, if deemed appropriate, approved by the Audit and Finance Committee. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance review and approval is not practicable, the Audit and Finance Committee will review, and, in its discretion, may ratify the related person transaction if it deems ratification appropriate under the circumstances. The policy also permits the chair of the Audit and Finance Committee to review and, if deemed appropriate, approve proposed related person transactions that arise between Audit and Finance Committee meetings, subject to ratification by the Audit and Finance Committee at its next meeting. Any related person transactions that are ongoing in nature are reviewed annually.
A related person transaction reviewed under the policy will be considered approved or ratified if it is authorized by the Audit and Finance Committee after full disclosure of the related person’s interest in the transaction. As appropriate for the circumstances, the Audit and Finance Committee will review and consider:
•The related person’s interest in the related person transaction;
•The approximate dollar value of the amount involved in the related person transaction;
•The approximate dollar value of the amount of the related person’s interest in the transaction without regard to the amount of any profit or loss;
•Whether the transaction was undertaken in the ordinary course of our business;
•Whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unrelated third party;
•The purpose of, and the potential benefits to us of, the transaction; and
•Any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.
The Audit and Finance Committee may approve or ratify the transaction only if the Audit and Finance Committee determines that, under all of the circumstances, the transaction is consistent with our best interests. The Audit and Finance Committee may impose any conditions on the related person transaction that it deems appropriate. In addition to the transactions that are excluded by the instructions to the SEC’s related person transaction disclosure rule, the Board has determined that the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not related person transactions for purposes of this policy:
•Interests arising solely from the related person’s position as an executive officer of another entity (whether or not the person is also a director of such entity) that is a participant in the transaction, where (a) the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity, (b) the related person and his or her immediate family members are not involved in the negotiation of the terms of the transaction and do not receive any special benefits as a result of the transaction, (c) the amount involved in the transaction equals less than the greater of $1 million dollars or 2% of the annual gross revenues of the other entity that is a party to the transaction, and (d) the amount involved in the transaction equals less than 2% of our annual gross revenues; and
•A transaction that is specifically contemplated by provisions of our third restated certificate of incorporation (the “Certificate of Incorporation”) or By-laws.
The policy provides that transactions involving compensation of executive officers shall be reviewed and approved by the Compensation Committee in the manner specified in its charter.
Since January 1, 2024, there were no related party transactions, nor are there currently any proposed related party transactions, which in accordance/ with SEC rules, would require disclosure in this proxy statement.

Indemnification Agreements
We have entered into an indemnification agreement with each of our directors and executive officers. Our form of indemnification agreement, and our Certificate of Incorporation and By-laws, require us to indemnify and advance expenses to these persons to the full extent permitted by Delaware law. We also intend to enter into an indemnification agreement with each of our future directors and executive officers.
QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING

Why am I receiving this proxy statement and accompanying proxy card?
This proxy statement and the accompanying proxy card are being furnished to you by the Board of Directors (the “Board” or “Board of Directors”) of Emergent BioSolutions Inc. (“Emergent”, the “Company”, “we”, “us” or “our”) to solicit your proxy to vote your shares at our 2025 annual meeting of stockholders and at any adjournment or postponement of the meeting. The annual meeting will be conducted in virtual format via live audio webcast on April 30, 2025, at 9:00 a.m. Eastern Time. Stockholders can attend the meeting via the internet at www.virtualshareholdermeeting.com/EBS2025.
This proxy statement describes matters on which you may vote and provides you with other important information so that you can make informed decisions. You are requested to vote on each of the proposals described in this proxy statement and are invited to attend the virtual annual meeting.
What does it mean to vote by proxy?
It means that you give someone else the right to vote your shares in accordance with your instructions. In this way, you ensure that your vote will be counted even if you are unable to attend the annual meeting. When you submit your proxy by internet, by telephone or by mail, you appoint each of Joseph Papa, our president and chief executive officer, Richard Lindahl, our executive vice president, chief financial officer and treasurer, and Jessica Perl, our senior vice president, general counsel and corporate secretary, or their respective substitutes or nominees, as your representatives — your “proxies” — at the meeting to vote your shares in accordance with your instructions. If you give your proxy but do not include specific instructions on how to vote, the individuals named as proxies will vote your shares as the Board recommends, and may vote in their discretion with respect to any other matters properly presented at the annual meeting.
Who is entitled to vote at the annual meeting?
Holders of the Company’s common stock as of the close of business on the record date, March 3, 2025, may vote by proxy or virtually at the annual meeting. As of the close of business on March 3, 2025, there were 54,337,026 shares of common stock outstanding and entitled to vote and held by 41 holders of record. The common stock is the only outstanding voting security of the Company, and each share of common stock is entitled to one vote on each matter properly brought before the annual meeting.
What is the difference between holding shares as a stockholder of record and as a beneficial owner?
You may own shares of the Company’s common stock in two different ways:
•Record Ownership. If your stock is represented by one or more stock certificates registered in your name or if you have a Direct Registration System account in your name evidencing shares held in book-entry form, with our transfer agent, Broadridge Financial Solutions, Inc., and you are a “stockholder of record.”
•Beneficial Ownership. If your shares are held in a brokerage account or by a bank or other nominee, those shares are held in “street name” and you are considered the “beneficial owner” of the shares. As the beneficial owner of those shares, you have the right to direct your broker, bank or other nominee how to vote your shares, and you will receive separate instructions from your broker, bank or other nominee describing how to vote your shares.
If I hold shares in street name by my bank or broker, will my bank or broker automatically vote my shares for me?
If you hold shares through an account with a bank or broker, the voting of the shares by the bank or broker when you do not provide voting instructions is governed by the rules of the NYSE. These rules allow banks and brokers to vote shares in their discretion on “routine” matters for which their customers do not provide voting instructions. On matters considered “non-routine,” banks and brokers may not vote shares without your instruction.

62 | 2025 Proxy Statement |  |  | EMERGENT BIOSOLUTIONS INC.

| Policies and Procedures for Related Person Transactions

What is a “broker non-vote” and how would it affect the vote?
Shares that banks and brokers are not authorized to vote on a particular proposal are referred to as “broker non-votes.” The ratification of the Company’s independent registered public accounting firm is considered a routine matter. Accordingly, banks and brokers may vote shares on this proposal without your instructions and, as a result, we do not expect to receive broker non-votes with respect to this proposal.
We expect all other proposals to be voted upon at the annual meeting to be considered to be non-routine, meaning that banks and brokers would not be able to vote your shares on those proposals without your instructions. Please note that if you want your vote to be counted on those proposals, including the election of directors, you must instruct your bank or broker how to vote your shares. If you do not provide voting instructions, no votes will be cast on your behalf with respect to those proposals.
Broker non-votes will be counted for purposes of establishing a quorum but will not affect the outcome of the vote on any proposal presented at the annual meeting.
What is an “abstention” or a “vote withheld” and how would it affect the vote?
An “abstention” occurs when a stockholder submits a proxy with explicit instructions to decline to vote regarding a particular matter and a “vote withheld” occurs when a stockholder submits a proxy with explicit instructions to decline to vote in favor of a director nominee. Abstentions and votes withheld are counted as present for purposes of determining a quorum. Because an abstention is not considered to be a vote “cast” for a particular matter, it will have no effect on any of the proposals presented at the annual meeting. In addition, because a vote withheld with respect to the election of directors does not have legal effect under the existing plurality voting standard, a director may be elected with as little as one affirmative vote.
What does it mean if I receive more than one proxy card from the Company?
It means that you have more than one account for your shares. Please vote by internet or telephone using each of the identification numbers, or complete and mail all proxy cards to ensure that all of your shares are voted.
What is “householding” and how does it affect me?
The SEC has adopted rules that permit companies and intermediaries, such as brokers, to satisfy delivery requirements for proxy statements with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or proxy statement and annual report addressed to those stockholders. This process, commonly referred to as “householding,” potentially provides extra convenience for stockholders and cost savings for companies. Because we utilize the “householding” rules for proxy materials, stockholders who share the same address generally will receive only one copy of the Notice of Internet Availability of Proxy Materials or proxy statement and annual report, unless we receive contrary instructions from any stockholder at that address. If you prefer to receive multiple copies of the Notice of Internet Availability of Proxy Materials or proxy statement and annual report at the same address, additional copies will be provided to you promptly upon request. If you are a stockholder of record, you may obtain additional copies upon written or oral request to Emergent BioSolutions Inc., Attn: Investor Relations, 300 Professional Drive, Gaithersburg, Maryland 20879; Telephone: (240) 631-3200, Email: investorrelations@ebsi.com. Eligible stockholders of record receiving multiple copies of the Notice of Internet Availability of Proxy Materials or proxy statement and annual report can request householding by contacting us in the same manner.
If you are a beneficial owner and hold your shares in a brokerage or custody account, you can request additional copies of the Notice of Internet Availability of Proxy Materials or proxy statement and annual report or you can request householding by notifying your broker, bank or other nominee.
How do I attend the annual meeting? When and where will the annual meeting be held?
The annual meeting will be held on April 30, 2025. This year, we will be once again hosting the annual meeting live via the internet. You will not be able to attend the annual meeting in person. Any stockholder can listen to and participate in the annual meeting live via the internet at www.virtualshareholdermeeting.com/EBS2025. To participate in the virtual annual meeting, you will need the 16-digit control number which appears on your proxy card, voting instruction form or notice you will receive. The annual meeting webcast will begin promptly at 9:00 a.m., Eastern Time. We encourage you to access the annual meeting webcast prior to the start time. Online check-in will begin, and stockholders may begin submitting written questions, at 8:45 a.m., Eastern Time, and you should allow ample time for the check-in procedures. If you do not have a control number, you may attend as a guest (non-stockholder), but will not have the option to vote your shares at the virtual meeting.

Policies and Procedures for Related Person Transactions |

What if during the check-in time or during the annual meeting I have technical difficulties or trouble accessing the virtual meeting?
We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual meeting. If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the Virtual Stockholder Meeting log in page.
Why are we holding the annual meeting virtually?
We have determined that hosting a virtual annual meeting of stockholders will provide expanded access, improved communication, and cost savings. Hosting a virtual meeting enables increased stockholder attendance and participation since stockholders can participate from any location around the world. We intend that the virtual meeting format will provide stockholders a similar level of transparency to the traditional in-person meeting format and we will take steps to ensure such an experience. Our stockholders will be afforded the same opportunities to participate at the virtual annual meeting as they would at an in-person annual meeting of stockholders. Our virtual annual meeting allows stockholders to submit questions and comments before and during the annual meeting. After the annual meeting, we will be answering stockholder questions that comply with the rules of conduct for the annual meeting; which will be posted on the virtual annual meeting web portal. To the extent time does not allow us to answer all of the appropriately submitted questions, we will answer them in writing on the Company’s website at www.emergentbiosolutions.com under the section “Investors,” soon after the meeting. If we receive substantially similar questions, we will group such questions together and provide a single response to avoid repetition.
How can I change my vote or revoke my proxy?
If you hold shares in your own name as a stockholder of record, you may change your vote or revoke your proxy at any time before voting begins by:
•Giving notice of revocation to our Corporate Secretary, at Emergent BioSolutions Inc., 300 Professional Drive, Gaithersburg, Maryland 20879 (by mail or overnight delivery);
•Executing and delivering to our Corporate Secretary, at the address noted above, a proxy card relating to the same shares bearing a later date;
•Voting by the internet or telephone prior to the time the voting facilities close (your latest internet or telephone vote will be counted); or
•Logging onto and voting at the virtual annual meeting.
If you decide to revoke or change your vote other than by voting at the annual meeting, we must receive the notice of revocation or new vote by 11:59 p.m., Eastern Time, on Tuesday, April 29, 2025, the date prior to the date of the annual meeting.
If your shares are held in “street name,” you must contact your broker, bank or other nominee to revoke or change your vote. The revocation or change must be made by the broker, bank or other nominee before the annual meeting.
What is the “quorum” for the annual meeting and what happens if a quorum is not present?
In order to conduct business at the annual meeting, the holders of at least a majority of the total number of shares of the Company’s common stock issued and outstanding and entitled to vote as of the March 3, 2025, record date, or 54,337,026 shares, must be present in person or represented by proxy. This requirement is called a “quorum.” If you vote by internet or by telephone, or submit a properly executed proxy card, your shares will be included for purposes of determining the existence of a quorum. Proxies marked “abstain” or “withhold” will be counted in determining the presence of a quorum. If the shares present in person or represented by proxy at the annual meeting are not sufficient to constitute a quorum, the annual meeting may be adjourned to a different time and place to permit further solicitations of proxies sufficient to constitute a quorum.
Does the Company offer an opportunity to receive future proxy materials electronically?
Yes. If you vote on the internet, simply follow the prompts for enrolling in electronic proxy delivery service. This will reduce our printing and postage costs, as well as the number of paper documents you will receive.
If you are a stockholder of record, you may enroll in this service at the time you vote your proxy or at any time after the annual meeting and can read additional information about this option and request electronic delivery by going to www.proxyvote.com. If you hold shares in street name, please contact your broker, bank or other nominee to enroll for electronic proxy delivery.

| Policies and Procedures for Related Person Transactions

Who will conduct the proxy solicitation and who will bear the cost?
The costs of soliciting proxies will be borne by us. The solicitation is being made primarily through the mail and electronic mail, but our directors, officers and employees may also engage in the solicitation of proxies in person, by telephone, electronic transmission or by other means. No compensation will be paid by us in connection with the solicitation of proxies, except that we may reimburse brokers, banks, custodians, nominees and other record holders for their reasonable out-of-pocket expenses in forwarding proxy materials to beneficial owners.
Who will count the votes?
Broadridge Financial Solutions, Inc. will tabulate the votes cast by internet, telephone and mail. Richard Lindahl will tabulate any votes cast at the annual meeting and will act as inspector of election to certify the results.
Where can I find the voting results of the meeting?
We will publish the voting results in a Form 8-K filed with the SEC within four business days after the annual meeting. You can read or print a copy of that report by going to either the Company’s website at www.emergentbiosolutions.com under the section “Investors –Financials – SEC Filings” or the SEC’s website at www.sec.gov.
Will a list of stockholders entitled to vote at the annual meeting be available?
A list of stockholders of record as of March 3, 2025, the record date, will be available for inspection by stockholders for any purpose germane to the annual meeting during normal business hours for the ten days prior to the meeting date, at our corporate headquarters at 300 Professional Drive, Gaithersburg, Maryland 20879. This list will also be available during the virtual annual meeting for examination by any stockholder at www.virtualshareholdermeeting.com/EBS2025.

Additional Matters
Other Matters
Our Board has no knowledge of any other matters that may come before the meeting. However, if any other matters are properly presented at the meeting, it is the intention of the persons named in the accompanying proxy to vote, or otherwise act, in accordance with their judgment on those matters.

Appendix A
DEFINITIONS AND RECONCILIATIONS OF NON-GAAP TO GAAP FINANCIAL MEASURES

Certain financial measures presented in our proxy statement have not been presented or prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). Certain of these financial measures are considered not in conformity with GAAP (“non-GAAP financial measures”) under the rules promulgated by the Securities and Exchange Commission.
We define Adjusted EBITDA, which is a non-GAAP financial measure, as net loss before income tax provision (benefit), interest expense, net, depreciation, amortization of intangible assets, excluding the impact of changes in fair value of financial instruments, acquisition and divestiture-related costs, severance and restructuring costs, settlement charges, net, exit and disposal costs, impairment charges, gain (loss) on sale of business, non-cash amortization charges, contingent consideration milestones and other income (expense) items. We believe that this non-GAAP financial measure, when considered together with our GAAP financial results and GAAP financial measures, provides management and investors with a more complete understanding of our operating results, including underlying trends. In addition, EBITDA is a common alternative measure of operating performance used by many of our competitors. It is used by investors, financial analysts, rating agencies and others to value and compare the financial performance of companies in our industry, although it may be defined differently by different companies. Therefore, we also believe that these non-GAAP financial measures, considered along with corresponding GAAP financial measures, provide management and investors with additional information for comparison of our operating results with the operating results of other companies.
We define Adjusted Net Loss, which is a non-GAAP financial measure, as net loss excluding the impact of changes in fair value of financial instruments, acquisition and divestiture-related costs, severance and restructuring costs, settlement charges, net, exit and disposal costs, impairment charges, gain on sale of business, non-cash amortization charges, contingent consideration milestones, and other income (expense) items. Management uses Adjusted Net Loss to assess total Company operating performance on a consistent basis. We believe that these non-GAAP financial measures, when considered together with our GAAP financial results and GAAP financial measures, provide management and investors with an additional understanding of our business operating results, including underlying trends.
Non-GAAP financial measures are not defined in the same manner by all companies and may not be comparable with other similarly titled measures of other companies. In addition, non-GAAP financial measures used for computing executive officer annual incentive pay may be defined differently from similarly titled measures used for financial reporting purposes. Non-GAAP financial measures should be considered in addition to, but not as a substitute for or superior to, the information contained in our Consolidated Statements of Operations.
