Filed by: Harris Corporation Commission File No. 1-3863 Pursuant to Rule 425 under the Securities Act of 1933 and deemed filed pursuant to Rule 14a-12 under the Securities Exchange Act of 1934 Subject Company: L3 Technologies, Inc. Commission File No. 1-37975 IMO Icebreaker: Carrie George and Bob Leskow on Exploring Opportunities to Become More Agile Bob Leskow and Carrie George have both an intricate challenge and an exciting opportunity before them: Planning to harmonize the 2,500- employee Finance function across L3 and Harris. “As we work through this process, we’ve been very intentional about considering each other’s strengths while also seeing if there are additional solutions beyond what we’re currently doing,” says George, IMO Finance Lead and Senior Director of Finance for Harris. “We plan to take the best of both and add in some new ideas that will help us streamline the overall Finance function post-close.” “The pace can be likened to running a relay race while navigating a maze at the same time,” adds Leskow, L3’s IMO Finance Lead and former CFO for Aerospace Systems. “It’s both challenging and exciting, but we also must work together as a team to win. We have to rely on the expertise of the L3 and Harris leads of six interdependent subteams and coordinate with them on a weekly basis to ensure smooth handoffs and the overall success of the integration.” The subteams’ scope of operations is wide-ranging, and each will have distinct responsibilities when the merger closes: • Accounting will be responsible for closing the books, external reporting and passing audits. • Financial Planning & Analysis (FP&A) will handle consolidation of financial results and forecasts, driving external guidance. • Compliance will ensure adherence to government regulations and coordinate government communications and indirect cost allocations, with an initial focus on corporate expenses. • Tax will close the books at the end of the fiscal year and prepare new tax provision estimates. • Treasury will ensure proper structure to meet financial obligations at close. • Delegation Authority will coordinate management of corporate policies and procedures for decision-making and signing authority. According to Leskow and George, detailed planning is paramount, so they are taking a three-phased approach to managing the integration process:

• Phase 1: Close. Identify and work toward systems, tools and processes that need to be in place on the day of close. • Phase 2: Post-Close. Identify the tasks that cannot be worked until post-close due to limitations on data sharing. These tasks will be included in the 100-day plan. • Phase 3: Long-term Vision. Define a long-term vision for the combined company, which could take up to three years to fully roll out. “While preparing for close is our near-term objective, the end state is where we can really make a difference,” Leskow noted. “Our long-term goal is to improve processes and provide better tools for employees, so we can facilitate an even more agile and efficient workforce.” George echoed these thoughts, emphasizing that the integration team is preparing to put plans in place that will help the organization grow and offer employees new opportunities. “Take a program analyst in Finance, for example. We know that analysis is what they really enjoy doing,” George said. “If we can give them new tools to automate data entry, it will free up time for more analysis, which not only gives them more job satisfaction, but it also adds more value to the programs they support.” In the days immediately following close, Leskow says it will generally be business as usual, but as new systems, tools, policies and procedures are rolled out, communication and training will be provided to those affected. Whether looking short- or long-term, creating a combined Finance function that is stronger and more streamlined – and that employees are happy to be a part of – remains a primary goal. “I’m excited to have the chance to add value to what will become the combined L3 Harris culture,” George said. “It’s gratifying to have the opportunity to work with such talented people and know that our efforts will result in a more efficient and stronger L3 Harris Technologies.” Forward-Looking Statements Certain of the matters discussed in this communication are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.
