Kimberly A. Fields has become president and CEO of Dallas-based ATI Inc. as part of a planned leadership transition in which she succeeds Robert S. “Bob” Wetherbee, who becomes executive chairman.

ATI is a global producer of high-performance materials and solutions for the global aerospace and defense markets, and critical applications in electronics, medical and specialty energy.

Fields said that she is honored to lead a “fantastic team.”

“ATI is in a great position: we’re executing on a clear strategy, with tremendous capabilities and strong customer partnerships,” Fields said in a statement. “We’re ready to accelerate, delivering the high-performance materials that make our customers’ extraordinary achievements possible.”

She added that everyone with the company appreciates the leadership of her predecessor, Wetherbee, in “transforming this organization and positioning ATI for such great success.”

Fields served as ATI’s chief operating officer since 2022, and became president in July 2023. During her tenure, ATI said it has grown as one integrated operation, sharpening its operational advantages, increasing capacity and capability for the extraordinary materials customers value most.

Wetherbee now will serve as the company’s executive chairman of the board.

He was named president and CEO in 2018 and became board chair in 2020. Under his leadership, ATI said it transformed to become an aerospace and defense leader, growing share and creating value for customers and shareholders.

In February, when Fields was elected to succeed Wetherbee as president and CEO, he said that “ATI is well-positioned, on a clear path to $5 billion in revenue and $1 billion in EBITDA by 2027. We have the capabilities, and the team is aligned to deliver.”

He added: “As ATI’s next CEO, Kim will further accelerate our growth and value creation.”
