L3HARRIS INVESTOR LETTER 3Q 2022 Refer to endnotes on page 19 Page 2 When I reflect on this past quarter, I’m reminded of the movie title “The Good, the Bad and the Ugly.” Our strategy is sound and we’re winning, we’re reducing our guidance for the year and external factors continue to challenge our business. The Good: Our mission at L3Harris remains the same – be the non-traditional prime that creates innovative solutions via our Trusted Disruptor strategy to address the heightened threat environment for government customers seeking alternatives. With hard work from our team, this strategy is progressing as evidenced by several pivotal prime awards and a portfolio enhancing acquisition to further solidify our unique networking position. The combination of increased urgency among government customers and traction with our strategy led to a book-to- bill1 of nearly 1.2x in the quarter, which reflects strength across all segments. Pivotal prime awards include approximately $3.0 billion for U.S. Special Operations Command’s Armed Overwatch program, $800 million for satellites as part of SDA’s National Defense Space Architecture and nearly $400 million for an integrated U.S. Navy sensor and fire control system. L3Harris was also selected by the U.S. Air Force to be part of a digital infrastructure consortium to define requirements and standards for key networking solutions within its Advanced Battlefield Management System program. Post quarter close, we announced an agreement to acquire Viasat’s Tactical Data Links product line for $1.96 billion. This acquisition will enhance L3Harris’ networking capability and provide immediate access to the ubiquitous Link 16 waveform, better positioning the company to enable the DoD’s integrated architecture goal in JADC2. We look forward to closing the acquisition in the first half of 2023 and will remain opportunistic with our balance sheet. The Bad: Despite our progress, as well as rising demand, the current backdrop remains a challenge and has contributed to a reduction in our financial guidance for the year. Third quarter results fell short of our expectations. Reported revenue was flat year-over-year, but expanded 3% organically2 with growth in each business segment. Net margin and GAAP EPS were weighed down by goodwill impairments. Segment adjusted operating margin3 was down versus the prior year largely due to the macroeconomic environment that impacted program performance and timing, resulting in flattish non-GAAP EPS3. We reported cash flow from operating activities and adjusted free cash flow3 of over $500 million. On full-year guidance, we are reducing our outlook across all financial metrics to reflect the above factors carrying into the fourth quarter and, most notably, the timing of a Mideast aircraft missionization program and supply disruptions. Though challenges are ongoing, our team is focused on “controlling the controllables” such as key customer deliveries, our e3 cost savings program, employee engagement and capital allocation. and the Ugly: With the conflict between Russia and Ukraine entering its ninth month, threats still emanating from China and North Korea and political tension rising in the Mideast, geopolitical risks remain elevated. Accordingly, the urgency and commitment around increased funding to combat these risks have held steady. In several international markets such as France and Japan, efforts are underway to ramp defense spending over the medium term. In the U.S., the GFY23 DoD budget is showing strength; however, we began the government fiscal year with another continuing resolution, while mid-term elections are approaching and national debt is expanding. The lack of budget visibility continues to strain the industry, as well as our business, and runs contrary to urgent needs. We are actively engaged with our suppliers, though many are experiencing the same challenges related to material shortages, labor attrition and inflation straining the overall defense industrial base. We will be analyzing this situation over the next few months prior to providing our 2023 guidance. Notwithstanding the ongoing challenges, we are focused on executing our strategy of being the Trusted Disruptor and remain optimistic about growth opportunities for continued value creation.

Page 5 Refer to endnotes on page 19 L3HARRIS INVESTOR LETTER 3Q 2022 The increased urgency and focus related to global defense spending have been sustained for another quarter. Geopolitical tensions across Asia and the Middle East have been more prominent in recent months, while the conflict between Russia and Ukraine enters its ninth month. Customers, both domestic and international, continue to revisit spending levels to address threats across all domains, which L3Harris is positioned to support. The improving contracting environment and the company's unique opportunity set was evident with this quarter’s strong orders results. Funded book-to-bill1 was 1.19x, with strength across each segment, and total backlog expanded 1%, and 2% adjusted for divestitures, versus prior year. This keeps the current range of U.S. DoD budget proposals at $773 billion to $819 billion, indicating a 4%-10% increase versus GFY22. These mark-ups, as well as the PBR, highlight support for many L3Harris offerings across domains, including responsive satellites, Intelligence, Surveillance and Reconnaissance (ISR) aircraft, tactical communications, networked maritime systems and classified cyber solutions.

The CR is a risk the industry is monitoring alongside the mid-term elections, a growing budget deficit and the persistent uncertainty surrounding inflation impacts. Over the next six weeks, the U.S. Congress must act to resolve the CR to avoid it extending into 2023. As part of the current CR, an additional $12 billion Ukraine aid package was enacted, bringing the total to $66 billion. A portion of these funds are addressable for L3Harris solutions, including tactical communications, night vision goggles and ISR, among others.

In the aggregate, U.S. Government defense spending priorities supporting integrated deterrence through modernized solutions, as highlighted in the recent National Security Strategy, continue to validate L3Harris’ strategy of investing in future technologies through leading internal Research & Development (R&D) spend, along with innovation accelerators. In international markets, the North Atlantic Treaty Organization (NATO) continues to evolve its strategy on multiple levels. Several countries, including Finland and Sweden, are pursuing NATO membership, while existing members such as France have in recent months supported increased spending beyond the 2% of gross domestic product (GDP) target. Recently, additional countries such as Japan have followed similar paths with expanded defense budgets due to persistent threats. In international markets, the North Atlantic Treaty Organization (NATO) is evolving its strategy via increased troop levels, expanded membership and higher spending commitments. In regard to defense spending, NATO leadership noted its 2% of gross domestic product (GDP) target as being a “floor,” with the United Kingdom, Poland, Germany, Italy and others signaling larger commitments. Additional regions and countries, such as Japan and Taiwan, are following similar paths due to persistent threats. LHX International Revenues Last Twelve Months (LTM) Europe Asia-Pacific Middle East & North Africa Americas (excluding U.S.) With international expansion a key pillar of L3Harris’ growth strategy, the company is positioned to capitalize on demand and offer a range of solutions to customers, including aircraft missionization, fighter jet upgrades, maritime platform expansion, soldier modernization and resilient communications.

Page 9 Refer to endnotes on page 19 L3HARRIS INVESTOR LETTER 3Q 2022 The macroeconomic backdrop continues to present challenges. For L3Harris, supply chain disruptions, labor mobility and rising inflation have all had an impact that management is working to address. While the company has made progress in its efforts, impacts to program performance and timing have contributed to the reduced 2022 financial guidance. Longer-term effects, however, are anticipated to be limited given actions such as pricing adjustments and cost controls as well as a shorter-cycle portfolio mix that will help offset rising input costs including labor, material and overhead. Supply Chain Global supply chain disruptions stemming from shifts in demand, labor shortages and structural factors continue to create headwinds for a range of industries, including Aerospace & Defense. The effects of these disruptions have been pervasive throughout L3Harris’ portfolio and most acute for businesses that rely on electronic components, including tactical and public safety radios, night vision goggles and imaging sensors, among others. Supplier disruptions had a greater than expected impact on the third quarter. Revenues at product- based businesses were affected by ~$70 million in the quarter and ~$200 million year-to-date, reflecting consistent headwinds sequentially. However, the company still met key customer commitments and within Tactical Communications, the company’s largest product- based business, trends improved modestly quarter-over-quarter with the business delivering topline growth and expanding backlog from “pent- up” demand. Represents product-based portion of Tactical Communications business L3Harris continues to deploy strategies to address the current supply chain environment. They include longer-term commitments, inventory redesigns and building “smart inventory,” among others. In addition, the company has expanded its engagement with the supplier base from its top suppliers at merger to over 500,000 incorporating lower tiers. Nonetheless, L3Harris still anticipates headwinds to continue into year end and 2023. Labor Labor markets have tightened considerably over the last year and more recently have been characterized by rising wages and higher attrition across skill levels, attributed in part to increased labor mobility.

Page 10 Refer to endnotes on page 19 L3HARRIS INVESTOR LETTER 3Q 2022 The broader Aerospace & Defense industry and L3Harris have experienced similar trends, which the company to date has actively managed by offering flexible work arrangements and competitive wages, with a continual focus and prioritization of employee engagement. Since its formation, company headcount, adjusted for divestitures, has been stable, and year-to-date L3Harris has added ~6,000 new hires, including ~850 new college graduates. The labor market is anticipated to remain tight and, in the short term, continue to be a challenge for both supply chain and program execution. Over the long term, L3Harris expects revenue and labor trends to be aligned, pointing toward an upward bias. Inflation The above factors relating to supply chain disruptions and labor mobility alongside other factors have led to rising U.S. inflation in the high- single-digit range, with on-going uncertainty and risk regarding its duration. For L3Harris, impacts to its cost structure have steadily increased. In the third quarter, supply chain-related inflation was partially offset by mitigation strategies that included operational improvements, escalation clauses, supply chain negotiations and re-pricing efforts. In addition, for the full year, and consistent with current guidance, L3Harris expects inflation impacts to continue into year end and 2023. Over the long term, with a balanced portfolio of fixed-price and cost reimbursable contracts along with a relatively short duration of approximately one year, on average, for its backlog, the company is positioned to minimize potential impacts. In aggregate, the company anticipates these macroeconomic challenges to persist into 2023 with management’s focus on controllable factors to limit the effects relating to program performance and program timing as well as higher input costs from the rising supply chain, inflation and labor costs.

Page 11 L3HARRIS INVESTOR LETTER 3Q 2022 Refer to endnotes on page 19 3Q22 Highlights L3Harris has partnered with Embraer to develop an “Agile Tanker,” a tactical aerial refueling option to address the U.S. Air Force’s operational imperatives. The partnership expands the capabilities of Embraer’s KC-390 Millennium tactical tanker aircraft, including the addition of advanced boom operations and mission systems as well as JADC2 requirements. As part of the ongoing support for Ukraine military aid, the L3Harris Vehicle-Agnostic Modular Palletized ISR Rocket Equipment (VAMPIRE) was among the systems highlighted in recent Ukrainian aid packages. VAMPIRE is a portable solution that can be installed on most vehicles with a cargo bed for launching the advanced precision kill weapons system and other laser-guided munitions. L3Harris participated in the 2022 Rim of the Pacific exercise with the Nomad unmanned surface vehicle. Nomad is designed to support multiple maritime missions, providing ISR and maritime domain awareness. During the exercise, Nomad successfully operated autonomously, while maintaining vessel awareness and complying with collision avoidance guidelines. On October 17, Integrated Mission Systems (IMS) Segment President, Sean Stackley, became Senior Vice President, Strategy & Growth, for L3Harris. Succeeding Sean, Jon Rambeau joined the company as President of the IMS Segment. Jon is a veteran of the Aerospace & Defense industry, most recently serving as Vice President and General Manager, Integrated Warfare Systems and Sensors with Lockheed Martin.

Page 16 Refer to endnotes on page 19 L3HARRIS INVESTOR LETTER 3Q 2022 On October 3, L3Harris announced the signing of a definitive agreement to acquire Viasat’s TDL product line for approximately $1.96 billion, expanding the company’s resilient communication and networking capabilities. TDL Product Line Overview The TDL network, also known as Link 16, is integrated on over 20,000 military aircraft, ground vehicles, surface vessels and operating bases, enabling warfighters to securely share voice and data communications across all domains. The TDL business is comprised of approximately 450 employees, with operations focused in Carlsbad, CA. Strategic Rationale The acquisition aligns with L3Harris Trusted Disruptor strategy to provide customers innovative and alternative solutions. TDL technology will improve the company’s JADC2 capability and provide immediate access to Link 16 waveform, platforms, prime contracts and a path to Advanced Tactical Data Links (ATDL) for future, integrated solutions. TDL will expand the company’s commercial pricing portfolio focused on defense applications across all domains for DoD and U.S. allies as a prime contractor. L3Harris expects the acquisition to close in the first half of 2023, subject to required regulatory approvals and customary closing conditions. Financial Highlights > Purchase price of $1.96 billion, subject to customary adjustments > Transaction structured as an asset purchase, resulting in ~$500 million in gross tax benefits with a NPV of ~$350 million > LTM adjusted EBITDA multiple of ~14x, net of tax asset and with run rate cost synergies > LTM Revenue / Operating Margins3: ~$400 million / 20%+ > Transaction is expected to be accretive to revenue, segment operating margins3, non- GAAP EPS3 and adjusted FCF3,4 CAPITAL ALLOCATION Image/Viasat

Page 17 Refer to endnotes on page 19 L3HARRIS INVESTOR LETTER 3Q 2022 Integrated Mission Systems L3Harris has reduced its full-year outlook across all financial metrics, reflecting the timing and ramp of key awards and continued macroeconomic headwinds that impact program performance, program timing and volumes. The company expects organic revenue2 to be down ~2.0% year-over-year, with segment margins3 of ~15.5%, non-GAAP EPS3 in the range of $12.75 to $13.00, and adjusted free cash flow3,4 of ~$2.0 billion. IMS revenue is expected to be ~$6.8 billion and down ~3.0%, versus the prior outlook of the low end of $7.1 billion to $7.3 billion and up 2% to 4%. This is driven by the timing of an international ISR award and related revenue, as well as increased supply chain disruptions within Electro Optical. IMS operating margin is anticipated to be ~13.00%, versus a prior outlook of the low end of 13.50% to 13.75%, as a result of macroeconomic factors impacting volumes, program performance and higher input cost. 2022 Guidance Revenue ~$16.8B (vs. $17.3B - $17.7B, low end) Organic revenue change2 down ~2.0% (vs. up 1.0% - 3.0%, low end) Net income margin ~6.80% (vs. 12.00% - 12.25%, low end) Segment operating margin3 ~15.50% (vs. 16.00% - 16.25%, low end) GAAP EPS $5.80 - $6.05 (vs. $10.75 - $11.05, low end) Non-GAAP EPS3 $12.75 - $13.00 (vs. $13.35 - $13.65, low end) Operating cash flow4 ~$2.2B (vs. $2.4B - $2.5B, low end) Adjusted free cash flow3,4 ~$2.0B (vs. $2.15B - $2.25B, low end) 2022 Guidance by Segment Revenue Segment Operating Margin3 IMS ~$6.8B down ~3.0% (vs.up 2.0% - 4.0%, low end) ~13.00% (vs. 13.50% - 13.75%, low end) SAS ~$6.0B flat (vs. flat - up 2.0%, low end) ~12.00% (vs. 12.50% - 12.75%, low end) CS ~$4.2B down ~3.0% (vs. flat - up 2.0%) ~24.25% (vs. 24.25% - 24.50%, high end) FINANCIAL GUIDANCE

Continued traction in responsive space will largely be offset by pressure in the airborne businesses, as they transition to modernization over the coming years, and classified award timing within Intel & Cyber. SAS operating margin is expected to be ~12.00% versus the prior outlook of the low end of 12.50% to 12.75%, resulting from macroeconomic factors impacting program performance. Free Cash Flow and Capital Allocation The adjusted free cash flow3,4 guide of $2.0 billion, compared to the prior outlook of $2.15 billion to $2.25 billion, is primarily driven by the reduced outlook for revenue and margins as well as an increase in working capital stemming from the supply constrained environment. The company’s guidance continues to incorporate current tax regulations, which required the company to begin capitalizing and amortizing R&D at the beginning of 2022, resulting in a cash tax payment increase of ~$600 million, versus the prior of $600 million to $700 million. Net FAS/CAS pension adjustment ($M) ~$535 (vs ~$540) Net interest expense ($M) ~$275 (vs ~$265) Integration expenses ($M) ~$75 Effective tax rate (non-GAAP) ~14% (vs ~15%) Average diluted shares (million shares) ~193 Capital expenditures ($M) ~$300 2022 Other Financial Guidance Space & Airborne Systems Communication Systems CS revenue is expected to be ~$4.2 billion and down ~3.0% year-over-year versus the prior outlook of $4.3 billion to $4.4 billion, and flat to up 2.0%, from ongoing supply chain disruptions and the timing of new awards.

This includes incremental funding and adjustments to previous awards, and excludes unexercised contract options or potential orders under indefinite delivery, indefinite quantity contracts. The funded book-to-bill ratio is considered a key performance indicator in the Aerospace and Defense industry as it measures how much backlog is utilized in a certain period. 2Organic revenue and organic revenue change exclude the impact of completed divestitures; refer to non-GAAP financial measure (NGFM) reconciliations in the tables accompanying this Investor Letter and to the disclosures in the non-GAAP section of this Investor Letter for more information. 3Segment operating margin, non-GAAP operating income (loss), non-GAAP EPS, adjusted backlog, net-debt-to- EBITDA, non-GAAP tax rate and adjusted free cash flow (FCF) are NGFMs; refer to NGFM reconciliations in the tables accompanying this Investor Letter for applicable adjustments and/or exclusions and to the disclosures in the non- GAAP section of this Investor Letter for more information. 4Operating cash flow and adjusted FCF results and guidance (2022) assumes a provision in the Tax Cuts and Jobs Act of 2017 that went into effect on January 1, 2022 requiring companies to capitalize and amortize R&D expenditures over five years rather than deducting such expenditures in the year incurred is not modified, repealed or deferred beyond 2022, resulting in additional cash income tax payments of ~$600 million in fiscal 2022. Adjusted FCF excludes cash income taxes paid or avoided related to taxable gains and losses resulting from sales of businesses, and also reflects the types of adjustments and/or exclusions presented in the FCF and adjusted FCF NGFM reconciliation in the tables accompanying this Investor Letter; refer to the disclosures in the non-GAAP section of this Investor Letter for more information. ENDNOTES

Page 20 L3HARRIS INVESTOR LETTER 3Q 2022 This Investor Letter contains non-GAAP financial measures within the meaning of Regulation G promulgated by the Securities and Exchange Commission (“SEC”), including non-GAAP EPS, segment operating margin, non-GAAP segment operating income (loss) and adjusted free cash flow for the third quarters of 2022 and 2021; organic revenue change; segment operating income (loss) and margin for the Integrated Mission Systems and Communication Systems segments for third quarter of 2022; debt to net-debt-to-EBITDA (adjusted earnings before interest, taxes, depreciation and amortization ratio); adjusted backlog; adjusted tax rate and expected organic revenue change, segment operating margin, EPS, and adjusted free cash flow, non-GAAP effective tax rate for 2022; in each case, adjusted for certain costs, charges, expenses, losses or other amounts as set forth in the reconciliations of non-GAAP financial measures included in the financial statement tables accompanying this Investor Letter. A “non-GAAP financial measure” is generally defined as a numerical measure of a company’s historical or future performance that excludes or includes amounts, or is subject to adjustments, so as to be different from the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles (“GAAP”). L3Harris management believes that these non-GAAP financial measures, when considered together with the GAAP financial measures, provide information that is useful to investors in understanding period-over-period operating results separate and apart from items that may, or could, have a disproportionately positive or negative impact on results in any particular period. L3Harris management also believes that these non-GAAP financial measures enhance the ability of investors to analyze L3Harris business trends and to understand L3Harris performance. In addition, L3Harris may utilize non-GAAP financial measures as guides in forecasting, budgeting and long-term planning processes and to measure operating performance for some management compensation purposes. Non-GAAP financial measures should be considered in addition to, and not as a substitute for, or superior to, financial measures presented in accordance with GAAP. NON-GAAP FINANCIAL MEASURES

L3Harris management also believes that these non-GAAP financial measures enhance the ability of investors to analyze L3Harris’ business trends and to understand L3Harris’ performance. In addition, L3Harris may utilize non-GAAP financial measures as guides in its forecasting, budgeting, and long-term planning processes and to measure operating performance for some management compensation purposes.
