Keysight disclaims any intention to, and undertakes no responsibility to, update or revise any forward-looking statement, whether as a result of new information, a future event, or otherwise. The forward- looking statements contained herein include, but are not limited to, predictions, guidance, projections, beliefs, opinions, and expectations regarding the company's future goals, revenues, financial condition, earnings, and operations that involve risks and uncertainties that could cause Keysight's results to differ materially from those expressed in such statements. Such risks and uncertainties include, but are not limited to, impacts of supply chain constraints; inflation, recession or depression; geopolitical tension and conflict; impacts related to endemic and pandemic conditions; changes in the demand for current and new products, technologies, and services; customer purchasing decisions and timing; delays in customer spending, order cancellations; delays in delivery, and impacts of increased trade tensions and tightening of export control regulations. For additional risks and uncertainties that could impact Keysight's actual results, please see our latest Form 10-Q for the fiscal quarter ended January 31, 2023 included but not limited to the discussion under "Risk Factors” therein, which may be viewed at www.sec.gov. This presentation includes a number of different financial measures, both GAAP and non-GAAP, in analyzing and assessing the overall performance of the business, for making operating decisions and for forecasting and planning for future periods. Non-GAAP measures exclude primarily the impacts of amortization of acquisition- related balances, share-based compensation, acquisition and integration costs, restructuring and related costs, and any one-time adjustments that may have a material effect on the Company's expenses and income from operations calculated in accordance with GAAP. Also excluded are tax benefits or expenses that are not directly related to ongoing operations and which are either isolated or cannot be expected to occur again with any regularity or predictability. For future periods, most of these excluded amounts pertain to events that have not yet occurred and are not currently possible to estimate with a reasonable degree of accuracy. This limits our ability to provide a reconciliation of the expected non-GAAP earnings per share to the GAAP equivalent. The definitions of these non-GAAP financial measures may differ from similarly titled measures used by others, and such non-GAAP measures should be considered supplemental to and not a substitute for financial information prepared in accordance with GAAP. Keysight generally uses non-GAAP financial measures to facilitate management's comparisons to historic operating results, to competitors' operating results and to guidance provided to investors. In addition, Keysight believes that the use of these non-GAAP financial measures provides greater transparency to investors of information used by management in its financial and operational decision-making. Refer to appendix for more details on the use of non-GAAP financial measures. ✔ KEYSIGHT 3
