#### SECURITIES TRADING POLICY
The Company has a Securities Trading Policy (“Securities Trading Policy”) governing the purchase, sale and other dispositions of the Company’s securities that applies to directors, officers and employees and to the Company itself in the repurchase of its own securities. We believe our Securities Trading Policy and repurchase procedures are reasonably designed to promote compliance with insider trading laws, rules and regulations, and the listing standards applicable to the Company. A copy of the Company’s Securities Trading Policy was filed as Exhibit 19.1 to its Annual Report on Form 10-K for the year ended December 31, 2024.

#### Board Leadership Structure
The GCR Committee annually reviews the leadership structure of the Board. In 2024, the GCR Committee affirmed that having an independent director serve as non-executive Chair of the Board continues to be in the best interest of our shareholders. Under our Corporate Governance Guidelines, the Board does not have a policy on whether the roles of Chair of the Board and CEO should be separate or combined. Instead, the Board selects the structure that it believes will provide the most effective leadership and oversight for the Company in the circumstances.

Our CEO is responsible for setting our strategic direction and providing day-to-day leadership, while the Chair of the Board sets the agenda for Board meetings, presides over meetings of the full Board and provides regular experience-based consultation to our CEO. We believe this structure provides a greater role for the independent directors in the oversight of our Company and active participation of the independent directors in establishing priorities and procedures for our Board.

#### Board Self-Evaluation
The Board believes that robust and constructive self-evaluation is an essential element of good corporate governance, Board effectiveness and continuous improvement. Our Board and each of its committees annually conduct a self-evaluation to assess and identify opportunities to improve their respective performance.
