This Investor Letter contains non-GAAP financial measures (as listed on page ## 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. 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 non-GAAP financial measures enhance the ability of investors to analyze L3Harris business trends and to understand L3Harris performance. 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. See “Reconciliation of Non-GAAP Financial Measures” below for detail on the adjustments to our non-GAAP financial measures. Non-GAAP Financial Measures
