We believe all of our directors possess the following core skills crucial to a successful Board:

A substantial percentage of our nominees have the following critical skills and backgrounds that bring important perspectives to the boardroom:

The Company’s Corporate Governance Guidelines require that a majority of the members of the Board be independent of the Company’s executive leadership and its significant shareholders. For a director to be deemed “independent,” the Board must affirmatively determine that the director has no material relationship with the Company or its affiliates (either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company or its affiliates), or any person (including the director) that, with its affiliates, is the beneficial owner of 5% or more of the Company’s outstanding voting stock or any member of the executive leadership of the Company or

his or her affiliates. Material relationships include commercial, banking, industrial, consulting, legal, accounting, charitable and familial relationships. For making this determination, the Board has adopted a set of director independence standards as required by the NYSE. These independence standards can be found in the Company’s Corporate Governance Guidelines at www.swn.com.

Our Board has determined that all of the nominees for director, other than our CEO, Mr. Way, are independent under our applicable independence standards.

Each member of the Board is expected to bring a valuable and often different perspective to the governance of the Company. When these differing skill sets and backgrounds are combined in an environment of interaction and respect, they give a greater overall skill set to the

Board and provide a strong governance structure. Our Corporate Governance Guidelines, which are available on our website at www.swn.com, set forth certain criteria that apply to the selection of director candidates.

The Nominating and Governance Committee evaluates the qualifications of each director candidate against the foregoing criteria in making a recommendation to the Board concerning that individual’s election or re-election as a director, including members of the Nominating and Governance Committee. The Nominating and Governance Committee, with direct input and advice from our CEO, is responsible for assessing the appropriate mix of skills and characteristics required of Board members based on the Board’s needs at a given point in time and periodically reviews and updates the foregoing criteria as deemed necessary. The Company is committed to considering candidates for the Board regardless of gender, ethnicity and national origin. Any search firm retained to assist the Nominating and Governance Committee in seeking candidates is instructed to seek diverse candidates from traditional and nontraditional candidate groups.

In 2020, the Board added one new director, which means 56% of this year’s nominees have been added since 2017. Their selection followed a thorough search process, aided by an external search firm. The following key goals informed these choices:

Each director’s continuation on the Board is reviewed near the end of his or her term and before that director is reconsidered for election. As described more fully on page 25, the Nominating and Governance Committee conducts a peer review evaluation process for directors and, with this information and in consultation with the Chairman of the Board, reviews and assesses the contributions of those directors selected for re-election. At the conclusion of this process, the Chairman of the Nominating and Governance Committee reports the Nominating and Governance Committee’s conclusions to the full Board. Once a director reaches the age of 75, he or she may not be considered for re-election to the Board of Directors, with certain exceptions provided in our Corporate Governance Guidelines.

The Board recognizes the importance of soliciting new candidates for Board membership and that the needs of the Board, in terms of the relative experience and other qualifications of candidates, may change over time. Candidates for membership on the Board may be suggested by any director or shareholder, and the Board may retain professional search firms to identify suitable candidates. Shareholders may nominate candidates for directors by following the procedures described on page 26 under “Shareholder Nominations.”

The shares of common stock represented by the enclosed proxy will be voted as instructed by the shareholder for the election of the nominees named in this section. If no direction is made, the proxy will be voted “FOR” the election of all of the nominees named above other than in the case of broker non-votes, which will be treated as described below. This year, with no shareholders having made nominations, the number of nominees equals the number of directors to be elected. Our bylaws provide that, in any uncontested election of directors (an election in which the number of nominees does not exceed the number of directors to be elected), any nominee who receives a greater number of votes cast “FOR” his or her election than votes cast “AGAINST” his or her election will be elected to the Board.

Shares not represented in person or by proxy at the Annual Meeting, abstentions and broker non-votes, will have no effect on the election

of directors, other than counting for purposes of a quorum. Our bylaws also provide that any nominee who does not receive a majority of votes cast “FOR” his or her election in an uncontested election is expected to tender his or her conditional resignation to the Chairman of the Board promptly following the certification of the vote, which resignation shall be promptly considered through a process overseen by the Nominating and Governance Committee, excluding (other than in certain limited circumstances set forth in our bylaws) any nominees who did not receive a majority vote. If any nominee becomes unavailable for any reason, or if a vacancy should occur before the election, the shares of common stock represented by the enclosed proxy may be voted for such other person as the Board may recommend. The Company does not expect that any nominee will be unavailable for election.

Southwestern Energy recognizes that strong corporate governance plays an important part in achieving our objective of enhancing the Company’s long-term value for our shareholders. Executive leadership, led by the CEO, is responsible for running the Company’s operations, under the oversight of the Board of Directors.

The Board has adopted corporate governance principles that serve as the framework of the Board and its committees. From time to time, the Board revises its corporate governance policies in response to changing regulatory requirements, evolving best practices and the perspective of our shareholders and other stakeholders.

Southwestern Energy Company is committed to providing the energy that powers our world, today and into the future. Creating Value+ is SWN’s core goal, with a clear focus on continuous improvement, innovation, integrity and responsibility. We seek to create value for our shareholders while providing a safe and healthy workplace for

our people, acting as good environmental stewards and being respected members of the communities in which we operate. Our Corporate Responsibility Report provides additional insight into our operations, goals, strategy and performance. It is located at www.swn.com/responsibility.

The Board provides a process for shareholders and other interested persons to send communications to the independent Chairman of the Board, the non-employee directors as a group or any of the other directors, including the entire Board. Shareholders and other interested persons may send written communications to the non-employee directors, the Chairman of the Board or any of the other directors to

the attention of the Secretary, Southwestern Energy Company, 10000 Energy Drive, Spring, Texas 77389-4954. The Secretary will review, sort and summarize the communications and forward them to the intended recipient(s) on a periodic basis, but no less frequently than every calendar quarter.

The Board has four standing committees: the Audit Committee, the Compensation Committee, the Nominating and Governance Committee, and the Health, Safety, Environment and Corporate Responsibility Committee. In addition, the Board may from time to time authorize additional standing or ad hoc committees, as it deems

appropriate. The Board creates ad hoc committees from time to time for special matters, such as finance or strategy. The following table lists our director nominees’ standing committee assignments and chairmanships as of December 31, 2020.

During 2020, the Audit Committee, among other things:

During 2020, the Compensation Committee, among other things:

The Compensation Committee continued to engage Meridian Compensation Partners, LLC (“Meridian”) as its independent compensation consultant for 2020 to advise on all matters related to executive compensation. In particular, Meridian collected and provided quantitative competitive market data for peer companies and advised in the selection of the peer groups of companies for compensation levels and performance-based long-term incentives. The Compensation Committee has sole authority to retain and terminate consultants such as Meridian and determines the interaction between consultants and Company management and personnel. Meridian provides no other services to the Company other than supplying the Nominating and Governance Committee with comparative data for compensation of non-employee directors and providing the Company on a quarterly basis data to assist in valuing unvested performance units for the purpose of applying generally accepted accounting principles regarding liability award accounting, the fees for which are about $65,000 annually. The Compensation Committee regularly meets with Meridian without any Company officers or employees present.

During 2020, the Nominating and Governance Committee, among other things:

The Nominating and Governance Committee devoted time in 2020 to Board assessment and refreshment. The Committee engaged

in a lengthy and deliberate process, assisted by an outside search firm, of identifying and analyzing a qualified candidate whose skills and background complement those of the continuing directors and increase the collective knowledge and insights of our Board. In particular, the Committee deliberately sought out an individual with strategic perspectives on our industry, leadership experience, and other complementary skills for this stage in the Company’s history. The Company is committed to considering diverse candidates for the Board and the search firm was instructed to seek diverse candidates from traditional and nontraditional candidate groups. We were guided by the criteria set forth in our Corporate Governance Guidelines, which are available to view on our website at https://www.swn.com/investors/corporate-governance/.

Our Committee recommended, and the Board elected, S. P. “Chip” Johnson IV as a new independent director in 2020. He is the former President and CEO of Carrizo Oil & Gas and brings important experience to the Board’s mix of skills. The Committee also recommended, and the Board approved, certain realignments in the composition of our standing committees to take advantage of our new director’s skills. We have eight independent directors with a variety of backgrounds, both inside our industry and relevant to it.

During 2020, the Health, Safety, Environment and Corporate Responsibility Committee, among other things:

Currently an independent director, Catherine A. Kehr, serves as Chairman of the Board of Directors. At many times in our past, the Board has named the CEO as Chairman with an independent director serving as presiding, or lead, director. The Board may modify the current structure again in the future if it determines that it would be more effective and likely to advance the interests of the Company and its shareholders.

The independent directors are required to meet in executive sessions as appropriate matters for their consideration arise, but, in any event, at least once a year. During 2020, the Board conducted these executive

sessions at each of its regularly scheduled meetings. The agenda of these executive sessions includes such topics as the participating directors determine. The Chairman of the Board (or the presiding director if the CEO is Chairman) acts as the chair of all executive sessions and is responsible for coordinating the activities of the other outside directors, as required by our corporate governance guidelines and the NYSE listing standards. The Chairman (or the presiding director if the CEO is Chairman) also acts as the liaison director for any informal, confidential communications with the CEO outside of the normal committee and Board procedures.

The Board regularly reviews emergency and long-term succession plans for the CEO and other senior leadership positions. In assessing future possible CEOs, the independent directors identify the skills, experience and attributes they believe are required to be an effective CEO in light of the Company’s business strategies, opportunities and challenges. The Board also ensures that directors have substantial opportunities over the course of time to engage with possible succession candidates.

The Board also considers its own composition and succession plans. The Nominating and Governance Committee is responsible for establishing criteria for nominees, screening candidates (in consultation with the CEO), and upon review and feedback from the remaining directors, making a recommendation for final approval of candidates for the full Board. The decision to name a new director is made by the full Board.

Under our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws, our shareholders have the right to call a special meeting of shareholders and to nominate director candidates to appear in our proxy. Holders of at least 20% of our common stock meeting certain “net long” holding requirements may require the Secretary to call a special meeting. Our Amended and Restated Bylaws allow shareholders to nominate candidates for

director, as described in the section “Shareholder Nominations.” This includes a “proxy access” right. We have no supermajority voting requirements. Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws are available to shareholders at no charge upon request to the Secretary or on our website at www.swn.com.

Our Amended and Restated Bylaws permit shareholders to nominate directors for consideration at an annual meeting of shareholders. During the past year, no shareholder nominated a candidate for the Company’s Board pursuant to procedures discussed in our Amended and Restated Bylaws or otherwise formally suggested a candidate to the Nominating and Governance Committee.

The chairman of the meeting may disregard any nomination of a candidate for director if it is not made in compliance with the procedures in our Amended and Restated Bylaws or other requirements under the Securities Exchange Act of 1934, as amended. For more information

on shareholder participation in the selection of director nominees, please refer to Section 2.4 of our Amended and Restated Bylaws, which can be found on our website at www.swn.com under “Corporate Governance.”

It is the policy of the Nominating and Governance Committee to consider properly submitted shareholder nominations for directors as described under “Succession Planning.” In evaluating such nominations, the Nominating and Governance Committee seeks to address the criteria set forth under “Election of Directors–Selection Criteria for Nominees for Directors.”

A shareholder, or a group of up to 20 shareholders (with funds having specified relationships constituting a single shareholder), owning 3% or more of the Company’s outstanding common stock continuously for at least the preceding three years may nominate and include in the Company’s proxy materials director candidates constituting up to 20% of the Board or two directors, whichever is greater, provided that the shareholder(s) and the nominee(s) satisfy the requirements specified in the Amended and Restated Bylaws. Shares that have been loaned during any portion of the three-year holding period count as being owned as long as certain conditions for the recall of shares are met. This is in addition to the right of any shareholder to nominate director candidates outside the proxy access process.

To make a proxy access nomination, an eligible shareholder (as defined in our Amended and Restated Bylaws) generally must deliver a qualifying notice to the Secretary at the principal executive offices of the Company not less than 120 days nor more than 150 days prior to the first anniversary of the date that the Company first distributed its proxy statement to shareholders for the previous year’s Annual Meeting of Shareholders and otherwise comply with all of the requirements of the Amended and Restated Bylaws. For the 2022 Annual Meeting, we must receive notice of the nomination for inclusion in the Company’s proxy materials no earlier than November 9, 2021 and no later than December 9, 2021.

Our Amended and Restated Bylaws also allow any shareholder to nominate a candidate for election to the Board without the nomination included in the Company’s proxy materials by delivering written notice by mail to the Secretary at the principal executive offices of the Company generally not less than 90 days nor more than 120 days prior to the anniversary date of the immediately preceding Annual Meeting of Shareholders, assuming that meeting is held within 25 days of such anniversary. The notice must include information specified in the Amended and Restated Bylaws. For the 2022 Annual Meeting,

assuming it is held within 25 days of May 18, 2022, we must receive notice of intention to nominate a director no earlier than January 18, 2022 and no later than February 17, 2022. If the meeting is not held within 25 days before or after the first anniversary of the preceding year’s annual meeting, we must receive notice of a shareholder’s intention to nominate a director (or to introduce an item of business) no later than the close of business on the tenth day following the day on which we send notice of the annual meeting or otherwise publicly disclose such date, whichever first occurs.
