Our Strategy and Growth Initiatives

At nVent, we are inventing the electrified future. We are a global electrical manufacturing company that connects and protects mission-critical systems and infrastructure — from data centers to power utilities, from smart facilities to commercial buildings. It’s why some of the world’s leading companies bring their most complex challenges to us. We believe our growth strategy will continue to drive differentiated performance, supported by our focus on high-growth verticals, global growth and acquisitions, and new products and innovation.

With our focus onhigh-growth verticals, we continued to expand our portfolio in the infrastructure vertical, which now represents 45 percent of our sales. Data Center sales grew to $1billion, and we invested in expanded capacity for our liquid cooling solutions, as we see accelerating demand from AI data centers and high-performance computing.

The Electrical Product Group acquisition, expanded our engineered building solutions platform, adding switchgear and further integration capabilities. With increasing power demands, driven by AI data centers and the trend of electrification, we are well-positioned to provide solutions to support the build-out of electrical infrastructure.

New products and innovation continue to be a core element of our growth strategy. In 2025, new products contributed 10 points to our sales growth. At the Supercomputing 2025 show late last year, we showcased several new liquid cooling products, including a new cooling distribution unit (CDU) designed for the higher power densities and heat loads of AI data centers. We continue to innovate, working closely with customers, and we are proud to be in Nvidia’s partner network.

People and our culture continue to be key to our success. In 2025, we received numerous awards and recognitions for our efforts. Most notably, for the second straight year, we were recognized by Ethisphere as one of the World’s Most Ethical Companies®, reflecting our commitment to absolute integrity — one of our core values at nVent. For the fourth consecutive year, nVent earned a Great Place to Work® Certification™, which recognizes employers who create an outstanding employee experience. We were recognized on Newsweek’s World’s Greenest Companies list for our environmental sustainability performance. We also received a gold sustainability rating from EcoVadis, placing us in the top two percent of companies assessed in our industry and the 95th percentile of all businesses assessed. This year, we were also named to the 2025 Fortune Best Workplaces in Manufacturing & Production™ List. This honor highlights organizations that excel in creating positive, inclusive, and engaging environments. These are just a few of the many awards and recognitions that reinforce our people, and culture are differentiators for nVent.

Looking Ahead

Our transformation is driving our success and is evident in our performance. I am proud of our team and all we have accomplished this past year. I am even more excited about what we are building. We are a high-growth electrical company, well positioned within the trends of digitalization, electrification, and sustainability. Our future is bright.

Understanding the issues our shareholders care about is critical to good governance.

Executive Compensation Highlights

These executive compensation highlights should be read in connection with the Executive Compensation section of this Proxy Statement, including the Compensation Discussion and Analysis section (see page 31).

Our Compensation Philosophy

The Compensation and Human Capital Committee believes that the most effective executive compensation program aligns executive initiatives with shareholders’ economic interests. The Committee seeks to accomplish this by rewarding the achievement of specific annual and long-term and strategic goals that create lasting shareholder value. The Committee’s specific objectives include:

•

to motivate and reward executives for achieving annual and long-term financial objectives;

​

•

to align management and shareholder interests by encouraging employee stock ownership;

​

•

to provide rewards commensurate with individual and company performance;

​

•

to encourage growth and innovation; and

​

•

to attract and retain top-quality executives and key employees.

​

To balance these objectives, our executive compensation program uses the following direct compensation elements:

•

base salary, to provide fixed compensation competitive in the marketplace;

​

•

annual incentive compensation, to reward short-term performance against specific financial targets; and

​

•

long-term incentive compensation, to link management incentives to long-term value creation and shareholder return.

​

The Compensation and Human Capital Committee reviews total compensation for executive officers and the relative levels of each of these forms of compensation against the Committee’s goals. The mix of total direct compensation (shown at target) for 2025 for our Chair and Chief Executive Officer and the average of the other executive officers named in the Summary Compensation Table below (our “Named Executive Officers”) is shown in the charts below.
