Shares of L3Harris Technologies (LHX) declined approximately 3% during Monday’s session after the aerospace and defense company disclosed that CEO Christopher Kubasik had resigned immediately following an internal behavioral investigation.
The shares changed hands at $282.54, representing a 3.2% decrease, even as the S&P 500 experienced only a modest 0.1% dip.

According to the company’s statement, L3Harris “became aware of certain conduct by Kubasik that was not consistent with the values of the Company as outlined in its Code of Conduct.” The organization emphasized that these behavioral matters were entirely separate from financial disclosures, control mechanisms, customer interactions, or day-to-day business performance.
After conducting a thorough review with assistance from outside legal advisors, the board of directors determined that reaching a separation agreement with Kubasik served the company’s best interests.
Lewis Hay III, who was appointed Lead Independent Director and Independent Chairman of the Board, stated: “The Board and Chris have agreed that implementing our succession plan today is the right thing to do. We thank him for his service.”
The board selected Sam Mehta as the company’s new president and chief executive officer. Mehta came to L3Harris in 2023 and previously led the Space and Mission Systems division as well as the Communications and Spectrum Dominance segments, which collectively generate over 80% of the firm’s total revenues.
“I am honored by the opportunity to serve as President and CEO of L3Harris,” Mehta commented. “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.”
The leadership transition included two other executive changes. Lauren Barnes assumed the role of President of SMS, while Christopher Aebli became President of CSD, with both appointments taking effect immediately.
Kubasik’s tenure at the company spanned nearly a decade. He initially joined L3 Technologies in 2015, navigated the 2019 combination with Harris Corporation, assumed the chief executive position of the merged entity in June 2021, and directed the 2023 purchase of Aerojet Rocketdyne.
At the time Kubasik took over as CEO, LHX shares traded near $215. Prior to Monday’s session, the stock had climbed roughly 35% during his leadership, though this gain lagged the S&P 500 by approximately 45 percentage points across the same timeframe.
Rob Stallard, an analyst at Vertical Research Partners, observed on Monday that “it has not escaped investors’ attention that L3 Harris Technologies’ stock has underperformed its U.S. defense peers under Kubasik’s leadership,” noting that the underperformance relative to industry competitors stands at roughly 45 percentage points over a five-year span.
Stallard expressed cautious optimism about the incoming leader: “We have high regard for Sam Mehta, who in our experience has been an effective manager and a good communicator. He may be a catalyst for closing the performance gap.”
The stock faced headwinds even before Monday’s announcement. LHX had dropped nearly 20% since conflict escalated in Iran during early March, reflecting investor concerns about potential defense budget cuts if Democrats were to regain control of the House during the 2026 midterm elections.
Notwithstanding the executive transition, L3Harris confirmed its complete 2026 financial outlook, including projections for consolidated revenue, organic growth rates, segment operating margins, GAAP earnings per share, and free cash flow generation.
