WASHINGTON — L3Harris Technologies has terminated Chris Kubasik from his positions as chairman and chief executive officer following an internal investigation that determined he violated the company’s code of conduct, the defense contractor announced Monday.
Effective immediately, Sam Mehta, a defense industry veteran who currently heads L3Harris’s space business, will assume the role of chief executive. Lewis Hay, the board’s lead independent director, will succeed Kubasik as chairman.
The abrupt leadership change rattled investors, sending L3Harris shares down approximately 3 percent in morning trading. However, analysts suggest the transition is unlikely to have a lasting material impact on the company’s operations or strategy.
L3Harris declined to disclose the specific nature of the misconduct, stating only in a press release that it “became aware” of behavior by Kubasik “that was not consistent” with its code of conduct. The company emphasized that the matter was unrelated to financial reporting, internal controls, customer relationships, or operational performance. Following an investigation conducted with independent counsel, the board concluded that a separation agreement was in the company’s best interest.
Kubasik’s departure marks the second time his career has been derailed by a conduct issue. He joined L3 Technologies as chief operating officer in 2015 after resigning from Lockheed Martin in 2012, when he was CEO-elect, over an improper relationship with a subordinate. He became L3’s CEO in 2018 with a stated goal of transforming the company into a “sixth prime” contractor dealing directly with the Pentagon. Following the 2019 merger with Harris Corporation, he served as chief operating officer before ascending to the CEO role in 2021. During his tenure, L3Harris acquired Aerojet Rocketdyne in 2023.
The shakeup arrives weeks after the company reported second-quarter earnings, during which Kubasik and other executives announced a one-year delay — to 2027 — for the planned spinoff of the missile solutions business, citing market conditions. In Monday’s statement, L3Harris reaffirmed its 2026 financial guidance and reiterated its commitment to a previously announced $3 billion capital investment to expand solid rocket motor production and bolster supply chain resilience.
Analysts noted that while the departure invites speculation, the underlying business fundamentals remain intact. Robert Stallard of Vertical Research Partners wrote in a morning note that investors will likely conclude the management change does not impact the core business. He added that L3Harris has underperformed its U.S. defense peers under Kubasik’s leadership and expressed high regard for Mehta, suggesting the incoming CEO could be a catalyst for closing that performance gap.
Mehta brings extensive experience from top-tier defense primes, including serving as president of advanced structures at RTX’s Collins Aerospace and president of defense systems at Lockheed Martin’s Sikorsky unit. He joined L3Harris in 2023 as president of its communications unit and was promoted earlier this year to lead the combined space and mission systems and communications and spectrum dominance segments.
“I am honored by the opportunity to serve as President and CEO of L3Harris,” Mehta said in a statement. “Today, L3Harris has a portfolio purpose-built for the future of warfare, and we are well-positioned to continue executing our focused growth strategy as The Trusted Disruptor.”
In conjunction with the transition, Lauren Barnes, currently president of the spectrum superiority division, has been appointed president of space and mission systems. Christopher Aebli, currently president of mission critical communications, will serve as president of communications and spectrum dominance.
