EXECUTIVE COMPENSATION HIGHLIGHTS

We have designed our executive compensation program to meet our business objectives, including attracting and retaining top-level executive talent, using various compensation elements and to align executive pay with the long-term and short-term interests of our shareholders. We received more than 96% shareholder support for our Say-on-Pay vote in 2024. We recognize and reward our executive officers through compensation arrangements that link their pay to the Company’s performance, and we ensure an alignment of interests with our shareholders, by including a significant portion of total compensation consisting of at-risk performance-based compensation.

✔Significant portion of executive compensation is variable and entirely contingent on performance against pre-established Company and individual performance goals✘Repricing of options without stockholder approval
✔Incentive award metrics that are tied to key company performance measures✘Hedging or pledging transactions or short sales by executive officers or directors
✔One-year minimum vesting for equity awards✘Tax gross ups for Named Executive Officers
✔Double-trigger severance benefits upon a change-in-control✘Automatic single-trigger equity vesting upon a change-in-control
✔Limited perquisites✘Excise tax gross-ups under change-in-control agreements
✔Share ownership guidelines applicable to executive officers and independent directors✘Excessive pension benefits or defined benefit supplemental executive retirement plan
✔Compensation recoupment policies✘Excessive use of non-performance-based compensation
✔Annual Say-on-Pay vote by stockholders✘Excessive severance benefits
✔Independent compensation consultant

See “Compensation Discussion and Analysis (CD&A)” and “Components of 2024 Executive Compensation” for more information on our executive compensation program.

ECONOMIC, ENVIRONMENTAL AND SOCIAL HIGHLIGHTS

We are focused on helping ensure the work we do satisfies long-term energy needs in a way that balances the interests of our stakeholders. Guiding principles that shape and inform how we make many of our decisions include, but are not limited to:

-Requiring that people must be at the center of any effort aimed at shifting to a cleaner, more sustainable energy model.
-Recognizing the decisions we make have a lasting and meaningful effect on its customers, employees, the communities we serve, our shareholders, and other stakeholders.
-Having a balanced, holistic approach in identifying solutions that allow us to remain flexible and adaptable for future policy changes, advancements in technology, and changing market conditions.

We announced a goal of net-zero greenhouse gas emissions by 2040 covering both Scope 1 and Scope 2 emissions (“Net-Zero Goal”). Our Net-Zero Goal builds on greenhouse gas emission reductions achieved to-date and demonstrates that continued execution of our long-term business plan will drive further greenhouse gas emission reductions. We plan to achieve our Net-Zero Goal primarily through continuation and enhancement of existing programs, such as the retirement of coal-fired electric generation with low- or zero-emission electric generation, ongoing pipe replacement and modernization programs, and deployment of advanced leak detection technologies. In addition, we plan to advance other low- or zero-emission energy resources and technologies, which may include hydrogen, renewable natural gas, long-duration storage, and/or deployment of carbon capture and utilization technologies, if and when these become technologically and economically feasible.

We are keenly aware that in addition to being a business entity, we are also a social and community enterprise that includes our employees, partners, customers and the communities we serve.
