![](q4updatedoutlook002.jpg)© 2024 Lumentum Operations LLC 2 Forward Looking Statements and Financial Presentation This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These include statements regarding our guidance with respect to future net revenue, non-GAAP diluted earnings per share, and non-GAAP operating margins, and related assumptions. These forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those projected. Among the factors that could cause actual results to differ from those contemplated are: (a) uncertainty and volatility in the global markets, including uncertainty and volatility in the macroeconomic environment, volatility and uncertainty with respect to economic growth, inflationary pressures, changes in the political or economic environment, such as geopolitical conflicts, war, trade and export restrictions, including for certain rare earth minerals, and the imposition of tariffs or other duties, and the effect of such market disruptions on demand for our products, technology spending by our customers, our costs and expenses and our ability to obtain components for our products; (b) quarter-over-quarter product mix fluctuations, which can materially impact profitability measures due to the broad gross margin ranges across our portfolio; (c) decline of average selling prices across our businesses or increase in costs, either of which will also decrease our margins; (d) effects of seasonality; (e) the ability of our suppliers and contract manufacturers to meet production, quality, and delivery requirements for our forecasted demand; (f) changes in customer demand, including due to changes in inventory practices and end-customer demand; (g) our ability to attract and retain new customers, particularly in the cloud photonics and imaging and sensing markets; (h) the risk that our markets will not grow or develop as expected or that our strategies and ability to compete in those markets are not successful, (i) the risk that Lumentum's financing or operating strategies will not be successful; (j) risks related to our restructuring initiatives and changes to our operations, and (k) failure to successfully integrate Cloud Light into our business or that we will not achieve the expected benefits. For more information on these and other risks, please refer to the "Risk Factors" section included in the Company's Quarterly Report on Form 10-Q for the fiscal quarter ended March 29, 2025, filed with the Securities and Exchange Commission (the "SEC"). The forward-looking statements contained in this presentation are made as of the date hereof and the Company assumes no obligation to update such statements, except as required by applicable law. Unless otherwise stated, all financial results and projections are on a non-GAAP basis. Our GAAP results, details about our non-GAAP financial measures, and a reconciliation between GAAP and non-GAAP results can be found in our fiscal third quarter of 2025 earnings press release which is available on our web site, www.lumentum.com, under the investors section. We have not provided reconciliations from GAAP to non-GAAP measures for our outlook. A large portion of non-GAAP adjustments, such as stock-based compensation, acquisition related costs, amortization of acquired intangibles, amortization of acquired inventory fair value, restructuring and related charges, foreign exchange gains and losses, net, non-cash interest expense on convertible notes, intangible assets write-off, integration related costs, non-GAAP income tax reconciling adjustments, and other costs and contingencies unrelated to current and future cash flows, are by their nature highly volatile and we have low visibility as to the range that may be incurred in the future.
