PagerDuty (NYSE: PD) announced John DiLullo will serve as Chief Executive Officer starting May 11, 2026, replacing Jennifer Tejada who has led the company since 2016. Tejada will transition to Executive Chair of the Board of Directors.

"With retention stabilizing, new customer and expansion business accelerating, continued operating margin expansion and momentum in our AI-first Operations Cloud platform, I am confident this is the right time for this transition," Tejada stated.
