RTX CIO Robin Diamonte to Retire, Deputy Joe Fazzino Named Successor

Robin Diamonte

Robin Diamonte, the CIO of aerospace company RTX Corp., will retire early next year after serving in the role since December 2004, according to a company memo seen by CIO and dated December 12. Joe Fazzino, RTX’s deputy CIO, will succeed Diamonte in the role, effective January 5, 2026. Diamonte will then retire in March 2026, according to a person familiar with her plans.

Diamonte says she does not see retirement as slowing down. Instead, the woman who has been an industry leader through groups including the Pension Benefit Guaranty Corp. and the Committee on Investment of Employee Benefit Assets, says she will enjoy her time and continue to work on issues important to her.

“I still have a few months to go but I do know that retirement for me isn’t about slowing down—it’s about finally having the time to do the things I love: seeing more of the world, playing plenty of pickleball, helping people feel more confident about their financial future, and getting involved with boards and causes that matter to me,” Diamonte wrote in an email in response to questions.

Fazzino joined RTX—then United Technologies—in 2008, eventually overseeing fixed income, private equity and real estate at the company’s corporate pension. He was named deputy CIO in December 2021.

Fazzino was named to CIO’s NextGen list in 2019 and to CIO’s 40 Under 40 list in 2014.

In 2019, Diamonte was presented with CIO’s Lifetime Achievement Award. At CIO’s 2025 Industry Innovation Awards, she was named a winner in the category of corporate plans.

I’m grateful that Robin and Joe will work together to ensure a smooth transition.”

As CIO, Fazzino will report to Mitchill.

RTX managed $107 billion in assets as of December 31, 2024, including $47 billion in a defined benefit plan. Under Diamonte’s leadership, DB assets grew from $15 billion, while defined contribution assets grew to $58 billion from $12 billion.
