Moving fast requires trust, Moving forward requires disruption. Investor Letter 3Q 2023 October 26, 2023

Letter from the CEO PAGE 2 | L3HARRIS INVESTOR LETTER 3Q 2023 Refer to endnotes on page 16 Operationally at AR, my team and I are focused and actively working to stabilize and enhance performance on a few visible programs that are behind schedule. We are leveraging L3Harris standard tools, processes and global operations resources, and we expect to drive continuous improvement throughout the AR portfolio. At the foundation of this effort is a modernization plan that utilizes Defense Production Act funding to increase capacity and efficiency to support long-term growth. Regardless of the volatile and uncertain environment, we are focusing on what we can control and our third quarter results reflect our progress. I want to thank the more than 50,000 L3Harris employees for their focus on execution as we strive to meet commitments to our stakeholders. Christopher E. Kubasik Chair and Chief Executive Officer 3Q Fast. Facts. 3Q23 revenue vs. 3Q22 YTD funded book-to-bill1 EPS / non-GAAP EPS1 cash from ops / adjusted FCF1 dividends paid $32B 16% $2.02 / $3.19 $543M / $635M $216M 1.17x total backlog Our third quarter financial results reflect the momentum we are building and underscore the resilience and effectiveness of our Performance First focus. 3Q23 financial takeaways: Year-over-year • Strong backlog growth of 49% driven by continued demand and strategic, national security-focused acquisitions, providing longer- term visibility • Delivered a 5th consecutive quarter of revenue growth • Higher adjusted free-cash-flow performance Sequentially • Solid revenue growth • Margin expansion: net income margin expanded 30 bps and segment operating income margin expanded 20 bps ◦ IMS segment operating margin up 180 bps to 11.9% • Increased earnings per share • Double-digit growth in cash from operations and adjusted FCF1 Since closing the Aerojet Rocketdyne (AR) acquisition on July 28, the leadership team and I have been actively engaged with our new colleagues across various sites. These sessions reaffirm our acquisition thesis with strong customer relationships, an energized employee base, and increasing product demand amid a heightened threat environment. We are already seeing the benefits of combining our resources and expertise with AR’s propulsion and energetics capabilities. Investors, Customers, and Employees, National security is at the core of our mission and the customers we serve. Following the recent terrorist attacks in Israel, there are heightened geopolitical tensions worldwide further emphasizing the need for strengthened deterrence to support the U.S. and its allies. Despite these threats, the U.S. has begun the government fiscal year under a 48-day Continuing Resolution and with the looming threat of a government shutdown if Congress fails to act. Budgets will be further pressured as the U.S. attempts to balance priorities and a rising national debt. In times like these, our Trusted Disruptor strategy sets L3Harris apart from our peers. With a national security, technology-focused portfolio, we can meet our customers’ evolving needs across all domains. Demand for L3Harris solutions remains robust, and in the third quarter we received $5.0B in orders, bringing year-to-date funded book-to-bill to 1.17x. These orders were underpinned by strategic awards, including a $220 million contract for advanced solid rocket motors for the Army's Guided Multiple Launch Rocket System (GMLRS), and a $200 million prime contract to deliver Maritime Underwater Tracking Ranges for the Royal Australian Navy.

PAGE 9 | L3HARRIS INVESTOR LETTER 3Q 2023 Refer to endnotes on page 16 Incorporating Aerojet Rocketdyne L3Harris has updated its 2023 guidance to incorporate the five-month post-acquisition period for AR. There is no change to the underlying guidance excluding AR. The company now expects revenue of $19.2 billion to $19.4 billion, up from prior guidance of $18.0 billion to $18.3 billion as a result of including AR. The company also increased segment operating income to $2.8 billion to $2.9 billion as a result of additional income from AR, up from prior guidance of $2.7 billion to $2.8 billion. This results in expected segment operating margins of ~14.8% in 2023. Non-operating income includes an approximately $125 million increase in interest expense associated with debt to fund the AR acquisition resulting in total 2023 expected interest expense of approximately $545 million, up from prior guidance of $420 million. L3Harris 2023 Consolidated Guidance LHX excluding Aerojet Rocketdyne Aerojet Rocketdyne LHX Prior Current (no change) New Updated* Revenue YoY growth $18.0B - $18.3B up ~5.5% - 7.0% $18.0B - $18.3B up ~5.5% - 7.0% $1.0B+ NA $19.2B - $19.4B up ~13% - 14% Segment operating income1 $2.7B - $2.8B $2.7B - $2.8B ~$120M $2.8B - $2.9B Segment operating margin1 ~ 15% ~ 15% ~14.8% EPS1 $12.15 - $12.55 $12.25 - $12.45 $12.25 - $12.45 Cash flow1 $2.0B+ $2.0B+ $2.0B+ Financial Guidance Net FAS/CAS pension adjustment has also been updated to reflect a $15 million increase due to the incorporation of pension assets and liabilities related to AR. FAS/CAS net pension adjustments are now expected to be approximately $410 million in 2023. AR pension income is reported within the FAS / CAS pension adjustments. AR had previously reported pension income in segment margins. Other financial information related to guidance can be found in Table 5 - Other Financial Information and Net FAS / CAS Pension Adjustment. These updates result in a tightened non-GAAP EPS guidance of $12.25 to $12.45 per share, unchanged from the prior guidance at the midpoint. Adjusted free cash flow also remains unchanged and is still expected to be $2.0 billion+. * Assumes no U.S. Government shutdown

CS operating income is expected to be in the $1.20 billion to $1.23 billion range. Aerojet Rocketdyne (AR) AR revenue is expected to be more than $1.0 billion, reflecting the five-month post-acquisition period. AR operating income is expected to be $120 million. Space & Airborne Systems (SAS) SAS revenue is expected to be in the $6.7 billion to $6.8 billion range with bias toward the higher end, driven by increased demand for space systems. SAS operating income is expected to be in the $735 million to $760 million range also biased toward the higher end driven by strong year-to-date performance and the increase in space revenue. Integrated Mission Systems (IMS) IMS revenue is expected to be in the $6.7 billion to $6.8 billion range with bias toward the lower end driven primarily by negative EAC adjustments within ISR and macro headwinds. IMS operating income is expected to be in the $765 million to $800 million range with bias toward the lower end driven by the changes in revenue noted above, EAC adjustments and macro headwinds.

PAGE 11 | L3HARRIS INVESTOR LETTER 3Q 2023 Refer to endnotes on page 16 Now, following the attacks in Israel, the White House and Congress may consider providing funding for both countries via a supplemental measure or via separate pieces of legislation, either of which could be addressed separately from broader GFY24 budget negotiations. L3Harris is consistently experiencing robust demand for its offerings, as evidenced by its year-to-date total orders exceeding $16 billion and impressive year-to- date funded book-to-bill1 ratio of 1.17x. Continuing Resolution On September 30th, Congress passed a 48-day Continuing Resolution (CR) to fund the government through November 17th at government fiscal year (GFY) 2023 levels. Congress must pass all 12 appropriations bills before the CR expires or pass another CR to prevent a government shutdown. Quantifying the potential impact of an extended CR remains challenging at this time. The company is closely monitoring developments in Congress. While the GFY24 budget still needs to go to conference, it is worth noting that a consensus appears to be forming around the President's budget request at $842 billion. The CR did not include additional funding for Ukraine, despite the August White House request for $24 billion in aid and continued support for some level of assistance from many members of Congress.

Missiles & Munitions

PAGE 13 | L3HARRIS INVESTOR LETTER 3Q 2023 Refer to endnotes on page 16 Space to Grow - Following successful hardware and software integration and testing, in preparation for delivery, L3Harris is entering final checkout procedures on the four missile-tracking satellites for Space Development Agency (SDA) tracking tranche 0. Once launched, the satellites will form a robust, multilayered military satellite network for missile warning and defense, and demonstrate agility in scaling capabilities and solutions to align with an ever-evolving threat environment. Leveraging Innovative Solutions - The company delivered the first fighter aircraft of the Hornet Extension Project (HEP) from our state-of-the-art Canadian fighter aircraft center of excellence in Mirabel, Canada. L3Harris has responsibility for the majority of the design work and the entirety of the aircraft's modifications and upgrades, central to the HEP's success. Delivering First Compass Call Aircraft - L3Harris successfully delivered the first of ten EC-37B Compass Call aircraft to the U.S. Air Force for formal combined developmental and operational testing. As the platform integration prime, L3Harris seamlessly integrated the Compass Call mission system, ensuring that the cutting-edge EC-37B will empower the customer to continue serving its vital electromagnetic warfare mission. Propelling Innovation - L3Harris played a pivotal role in NASA's historic success in delivering the United States' first asteroid sample to Earth. Our propulsion technology was integral in propelling and steering the spacecraft throughout its mission, highlighting the reliability and performance of our in-space propulsion products, and reaffirming our dedication to advancing space exploration. ‘Trusted Disruptor’ strategy in action Operational Update Photo Credit: (NASA/Keegan Barber)

PAGE 14 | L3HARRIS INVESTOR LETTER 3Q 2023 Refer to endnotes on page 16 Stabilizing Operational Challenges Improving and consistent operational performance remains a key focus. Through management’s actions to address these challenges, the company has begun to realize stabilized improvement throughout the portfolio. In the third quarter, overall net EAC adjustments improved sequentially, continuing a recent favorable trend in performance, particularly in our program-based businesses. AR has identified operational bottlenecks and supplier challenges and is leveraging L3Harris standardized tools, processes and operations resources to improve, including developing a modernization plan that leverages Defense Production Act funding. Supply Chain & Labor L3Harris continues to see positive trends driven by supply chain resiliency initiatives. However, full supply chain recovery remains uneven. The company continues to work closely with suppliers to mitigate future potential impacts, and has been successful in mitigating most of these challenges to manage the evolving 'new normal' in supply chain operations. Labor attrition continues a measured and steady improvement for the fourth consecutive quarter, trending toward pre-pandemic levels. LHX NeXt In 1Q23 the company launched a multi-year, multi- phase enterprise transformation program called “LHX NeXt.” L3Harris expects the program to yield gross run-rate savings of $500 million exiting year 3 and invest approximately $400 million over a 3-year period. LHX NeXt differs from the L3 and Harris integration as this is the second phase to transform the business. These actions are more complex and require both one-time and on-going enabling investments back in the business. The company has made early progress on quick initiatives to streamline and optimize and is laying the foundation to capture targeted savings. Earlier this month, L3Harris established a multiyear strategic partnership agreement that strengthens the supply chain by identifying and streamlining manufacturing and design processes and improves the company’s capability, agility, and competitiveness. Functionally, the company has also established proposal centers of excellence, implemented a communications shared service and centralized talent acquisition, enabling reduced headcount and higher efficiency in those functional areas. L3Harris is in the early stages of implementing modernized IT systems and successfully developed and tested a unified data layer across disparate Enterprise Resource Planning systems. Further development is anticipated to provide opportunities to simplify processes that result in cost savings. Ultimately, net of reinvestment back in the business, LHX NeXt is anticipated to provide tailwind opportunity for margin expansion over the next three years. During our Investor Day in December, management will provide additional information about how these savings will strengthen the company's future financial profile. Operational Update

PAGE 15 | L3HARRIS INVESTOR LETTER 3Q 2023 Refer to endnotes on page 16 Capital Deployment > The company’s top capital deployment priority is debt repayment and it made progress during the third quarter by deploying the majority of FCF1 towards that objective, resulting in total debt of $13.5 billion as of September 30, 2023. L3Harris is targeting a leverage ratio of less than 3.0x > This objective implies a debt reduction goal of approximately $3.0 billion, to be achieved through the prioritization of capital allocation to debt repayments, potentially accelerated with proceeds from non-core asset divestitures > This strategic focus on debt reduction will enhance the company’s long-term financial flexibility, allowing for a balanced capital allocation approach that will optimize total shareholder return > In 3Q23, L3Harris returned $216 million in cash to shareholders through dividends > On October 20, 2023 the L3Harris Board of Directors declared a quarterly cash dividend of $1.14 per common share, payable December 1, 2023, to shareholders of record on November 17, 2023 Cash Flow > L3Harris reported 3Q23 cash flow from operations of $543 million, down versus 3Q22 primarily due to higher cash tax and interest payments. Adjusted free cash flow1 was $635 million, up versus 3Q22 primarily due to the exclusion of AR acquisition related expenses partially offset by higher capital expenditures Leverage > During the quarter, L3Harris had net borrowings of $4.7 billion primarily to fund the acquisition of AR. Net borrowings were derived from new issuances of 3, 10 and 30-year senior notes for a combined $3.3 billion and a $1.5 billion increase to outstanding commercial paper. As of September 30, 2023 the company’s outstanding commercial paper was $2.0 billion, which is included as a component of short-term debt > As of September 30, 2023, L3Harris’ net-debt-to- adjusted EBITDA1 leverage ratio was 3.7x Balance Sheet & Cash Flow Management Cash Flow ($M) $588 $546$543 $635 3Q22 3Q23 Operating Cash Flow Adjusted FCF1 Net-debt / adj.

FY'23 Third Quarter Summary OTHER FINANCIAL INFORMATION AND NET FAS/CAS PENSION ADJUSTMENT (Unaudited) support

PAGE 23 | L3HARRIS INVESTOR LETTER 3Q 2023 Non-GAAP Adjustment Definition Amortization of acquisition-related intangibles Consists of amortization of identifiable intangible assets acquired in connection with business combinations. Amortization charges are recorded over the estimated useful life of the related acquired intangible asset, and thus are generally recorded over multiple years. Additional cost of sales related to the fair value step-up in inventory sold Difference between the balance sheet value of inventory from the acquiree and the acquisition date fair value. Merger, acquisition, and divestiture- related expenses In 2023, transaction and integration expenses associated with TDL and AR acquisitions. In 2022, transaction and integration expenses associated with the L3Harris merger. Also, includes external costs related to pursuing acquisition and divestiture portfolio optimization, non-transaction costs related to divestitures and salaries of employees in roles established for and dedicated to planned divestiture and acquisition activity. Sale of asset group and business divestiture-related gains, net In 2023, related to gains or losses associated with business divestitures. In 2022, related to an asset sale in our Integrated Mission Systems segment. Impairment of goodwill and other assets In 2022, charges for goodwill impairment recorded at our Integrated Missions Systems and Space & Airborne Systems Segments related to a weakened outlook for precision weapons and other solutions and higher interest rates, and charges recorded at our Communication Systems segment related to a lower outlook on legacy platforms and higher interest rates. LHX NeXt Costs associated with transforming multiple functions, systems and processes to increase agility and competitiveness. The LHX NeXt effort is expected to continue for the next three years with one-time costs for workforce optimization, incremental IT expenses for implementation of new systems, third party consulting and other costs totaling $400M. We expect gross run-rate savings of $500M exiting year 3. In 3Q 2023, costs consisted of $33M for third-party consulting, workforce optimization, incremental IT, and other. Charges for severance and other termination costs Charges associated with a formal restructuring plan and primarily related to employee severance and benefit arrangements. In 2022 we incurred charges associated with severance and other benefits related to employees that accepted a voluntary retirement plan with an effective retirement date of September 30, 2022. Charges related to an additional pre- merger legal contingency Accrual associated with an ongoing legal matter that is disproportionately large related to our routine legal expenses or accruals. Non-operating income adjustments 2022 includes an $8 million adjustment for equity method investment earnings. This Investor Letter contains non-GAAP financial measures (NGFMs) (as listed on page 16 and defined by endnote 1 within this Letter) within the meaning of Regulation G promulgated by the Securities and Exchange Commission (SEC). L3Harris management believes excluding the adjustments outlined below for the purposes of calculating certain non- GAAP measures is useful to investors because these costs do not reflect our ongoing operating performance. While L3Harris has excluded certain items from its Non-GAAP financial measures, there is no guarantee that such items will not reoccur in future periods.These adjustments, when considered together with the unadjusted 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 adjustments to our NGFMs enhance the ability of investors to analyze L3Harris business trends, to understand L3Harris performance and to evaluate our initiatives to drive improved financial performance. L3Harris may utilize NGFMs as guides in forecasting, budgeting and long-term planning processes and to measure operating performance for some management compensation purposes. NGFMs should be considered in addition to, and not as a substitute for, or superior to, financial measures presented in accordance with GAAP. See “Reconciliation of Non-GAAP Financial Measures” below for detail on the adjustments to our NGFMs. Non-GAAP Financial Measures

PAGE 24 | L3HARRIS INVESTOR LETTER 3Q 2023 To supplement our condensed consolidated financial statements presented in accordance with U.S. generally accepted accounting principles (GAAP), we provide additional non-GAAP measures, including organic revenue, segment operating income and margin, non-GAAP operating income, non-GAAP EPS, net-debt-to-adjusted- EBITDA, and adjusted free cash flow (FCF). L3Harris management believes that these NGFMs, 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 NGFMs enhance the ability of investors to analyze L3Harris’ business trends and to understand L3Harris’ performance and to evaluate our initiatives to drive improved financial performance. In addition, L3Harris may utilize NGFMs as guides in its forecasting, budgeting, and long-term planning processes and to measure operating performance for some management compensation purposes. Any analysis of NGFMs should be used only in conjunction with results presented in accordance with GAAP. A reconciliation of these NGFMs with the most directly comparable financial measures calculated in accordance with GAAP follows. We also provide our expectation of forward-looking NGFMs, including expected non-GAAP EPS, segment operating income and margin, adjusted free cash flow and non-GAAP tax rate for the full-year 2023. A reconciliation of forward-looking NGFMs to comparable GAAP measures is not available without unreasonable effort because of inherent difficulty in forecasting and quantifying the comparable GAAP measures and the applicable adjustments and other amounts that would be necessary for such a reconciliation, including due to potentially high variability, complexity and low visibility as to the applicable adjustments and other amounts, which may, or could, have a disproportionately positive or negative impact on the company's future GAAP results, such as the integration of TDL and AR and costs associated with LHX NeXt on our results and other potential business divestiture-related gains and losses, and other unusual gains and losses, or their probable significance and extent of tax deductibility. The variability of the applicable adjustments and other amounts may have a significant, unpredictable impact on our future GAAP results. Reconciliation of Non-GAAP Financial Measures
