Appointment of Leader of Space & Mission Systems and Communications & Spectrum Dominance Segments On April 16, 2026, L3Harris Technologies, Inc. (the “Company”), through its wholly owned subsidiary, Aerojet Rocketdyne Holdings, Inc. (“AJRD”), entered into definitive agreements with the United States Department of War (the “Investor”). The agreements provide for the issuance and sale of shares of Series A Convertible Preferred Stock of AJRD (the “Series A Preferred Stock”) and warrants (the “Warrants”) to purchase common stock of AJRD (the “Common Stock”) for an aggregate purchase price of $1 billion. The purpose of the investment is to strengthen the U.S. defense industrial base by providing funding for AJRD to expand and modernize its facilities, accelerate research and development, and increase production capacity for critical technologies. The Series A Preferred Stock will be convertible into shares of AJRD’s Common Stock at the Investor’s option. In the event of an initial public offering (“IPO”) of AJRD’s Common Stock, the Series A Preferred Stock will automatically convert into Common Stock of the IPO Company at a conversion price equal to 80% of the price to the public in the IPO (the “IPO Price”) reflecting a mutually agreed-upon valuation that aligns with the strategic objectives of the investment, and the Warrants will be automatically exchanged for new warrants, which are exercisable from time to time to purchase 3% of the common stock of the IPO Company, on a fully diluted basis, with an average exercise price of 110% of the IPO Price. Upon completion of the IPO, the Investor is expected to own less than 10% of the IPO Company’s common stock on an as-exercised basis. The agreements contain customary representations, warranties, and covenants by the Company and the Investor. The Agreement also provides for certain registration rights for the shares of Common Stock issuable upon conversion of the Series A Preferred Stock. Under the terms of the agreements, AJRD may redeem the Series A Preferred Stock and Warrants held by the Investor under certain conditions.
