Simplify's Take

What believers are saying

  • Q2 2026 revenue reached $5.9 billion, with backlog climbing to a record $42 billion.
  • Management raised 2026 guidance to $23.2 billion-$23.7 billion after 7.3 billion orders.
  • Intuitive Machines will build 18 spacecraft for L3Harris's SDA Tranche 3 missile-tracking mission.

What critics are saying

  • Aug. 17, 2026 CEO ouster exposes governance weakness after misconduct review and abrupt board turnover.
  • U.S. government concentration is dangerous; 74% of year-to-date revenue came from federal customers.
  • Missile-production buildouts need years; any program slip, defect, or cancellation hits backlog conversion hard.

What makes L3Harris Technologies unique

  • L3Harris spans missile propulsion, secure communications, and space payloads across all warfighting domains.
  • Aug. 2026 Roman telescope launch showcases decade-long NASA integration and radiation-hardened optical systems.
  • July 27, 2026 PAC-3 agreement and THAAD expansion lock L3Harris into critical interceptor supply.

L3Harris tech powers NASA's Roman Space Telescope to map universe 1,000 times faster than Hubble

L3Harris Technologies has provided key components for NASA's Nancy Grace Roman Space Telescope, which recently launched successfully. The company supplied the 2.4-metre Optical Telescope Assembly and radiation-hardened electronics for the observatory, which will operate approximately 1 million miles from Earth. The telescope is designed to survey the cosmos 1,000 times faster than the Hubble Space Telescope. Once operational, it will conduct three primary surveys, including scanning roughly 12% of the entire sky in under 18 months to measure the universe's expansion rate and study supernova explosions from up to 8 billion years ago. The project represents more than a decade of collaboration between L3Harris and NASA's Goddard Space Flight Center. L3Harris has previously contributed technology to missions including the James Webb Space Telescope and Mars rovers.

L3Harris taps Intuitive Machines to build 18 spacecraft for $1.8B missile defence mission

L3Harris Technologies selected Intuitive Machines on 4 August to build 18 advanced spacecraft platforms for the Space Development Agency's Accelerated Missile Defense Tranche 3 mission. Intuitive Machines will manufacture and deliver the satellite platforms to host L3Harris' payload technology for national security space operations. L3Harris reported Q2 2026 revenue of $5.9 billion, an 8% year-over-year increase, with net income of $600 million. The company raised its full-year 2026 revenue guidance to $23.2 billion–$23.7 billion, backed by a $42.0 billion backlog. Intuitive Machines reported Q2 2026 revenue of $206 million, more than four times its prior-year level. However, the company posted an operating loss of $47 million and burned $84 million in cash during the quarter, leaving $367 million in cash. Its backlog expanded to a record $1.8 billion.

L3 Harris CEO ousted amid misconduct allegations, echoing 2012 Lockheed Martin exit

Christopher Kubasik has been ousted as CEO of L3 Harris following allegations of misconduct. According to Semafor, citing sources familiar with the matter, an investigation found he was engaged in an inappropriate relationship with a subordinate. This marks the second time Kubasik has been forced out of a leadership position under similar circumstances. In 2012, he was set to become CEO of Lockheed Martin but resigned after an ethics investigation confirmed he had a close personal relationship with a subordinate employee. L3 Harris, headquartered in Melbourne, Florida, announced Kubasik's departure on 17 August. The company said the misconduct was unrelated to financial reporting, controls, customer relationships or operational performance. Kubasik will retain some vested stock options but won't receive severance payments.

L3Harris CEO steps down after conduct review, shares fall 2.7%

L3Harris Technologies announced the immediate departure of CEO Christopher Kubasik following a conduct review, causing shares to fall roughly 2.7% in premarket trading Monday. The board appointed Sam Mehta as president and CEO, whilst Lewis Hay III became independent chairman. The company stated Kubasik's conduct was inconsistent with its Code of Conduct, though unrelated to financial reporting, controls, customer relationships, or operational performance. Following an investigation with independent counsel, the board entered into a separation agreement with Kubasik. Mehta joined L3Harris in 2023 and brings over 25 years of aerospace and defence leadership experience. He previously led segments comprising more than 80% of the company's total revenue. Despite the leadership change, L3Harris reaffirmed its 2026 consolidated revenue and financial guidance.

L3Harris completes hot-fire test of stage two rocket motor for Next Generation Interceptor program

L3Harris Technologies has successfully completed a hot-fire test of its stage two advanced large solid rocket motor for the Missile Defense Agency's Next Generation Interceptor programme. The company conducted the test as part of the Lockheed Martin team developing the homeland missile defense system. The test validated the system's design integrity, with the motor completing a full-duration burn in a simulated high-altitude, vacuum environment. Engineers evaluated performance in conditions mimicking Earth's upper atmosphere. L3Harris serves as the primary propulsion and control systems provider for NGI, producing both stage one and stage two rocket motors, plus the Attitude Control System and Divert and Attitude Control System. The company manufactures components across facilities in California, Virginia, Alabama, and Arkansas.
