Business Outlook

Lumentum expects the following for the fiscal first quarter of 2025:

• Net revenue in the range of $315 million to $335 million
• Non-GAAP operating margin of 0% - 3.0%
• Non-GAAP diluted earnings per share of $0.07 to $0.17

We have not provided reconciliations from GAAP to non-GAAP measures or the equivalent GAAP measure for non-GAAP measures in our outlook, as they cannot be provided without unreasonable effort. A large portion of non-GAAP adjustments, such as restructuring charges, stock-based compensation, non-GAAP income tax reconciling adjustments, acquisition related costs, and other costs and contingencies unrelated to current and future operations are by their nature highly volatile and we have low visibility as to the range that may be incurred in the future.

Use of Non-GAAP Financial Measures

In this press release, Lumentum provides investors with certain non-GAAP financial measures: gross profit, gross margin, research and development expense, selling, general and administrative expense, operating margin (loss), income (loss) from operations, interest and other income (expense), net, income before income taxes, provision for income taxes, net income (loss), and net income (loss) per share on a non-GAAP basis, as well as the non-GAAP measures of EBITDA and Adjusted EBITDA. Lumentum believes this non-GAAP financial information provides additional insight into the Company’s on-going business operations and results, as well as cash generation, and has therefore chosen to provide this information to investors for a more consistent basis of comparison and to help them evaluate the results of the Company’s on-going operations and enable more meaningful period to period comparisons. In addition, the Company believes that providing certain of these measures allows investors to better understand the Company’s operating performance and cash flows and, importantly, to evaluate the methodology and information used by management to monitor, manage, evaluate and measure the Company’s business, results of operations, and cash flows. However, these measures may be different from non-GAAP measures used by other companies, limiting their usefulness for comparison purposes. The non-GAAP financial measures used in this press release should not be considered in isolation from measures of financial performance prepared in accordance with GAAP. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, many of the adjustments to our GAAP financial measures reflect the exclusion of items that are recurring and will be reflected in our financial results for the foreseeable future. Further, these non-GAAP financial measures may not be comparable to similarly titled measurements reported by other companies.

Our non-GAAP measures used in this press release exclude (i) stock-based compensation, (ii) acquisition related stock-based compensation, (iii) acquisition related costs, (iv) amortization of acquired intangibles, (v) amortization of acquired inventory fair value adjustments, (vi) restructuring and related charges, (vii) foreign exchange (gains) losses, net, (viii) non-cash interest expense on convertible notes, (ix) gain on repurchase of convertible notes, (x) non-recurring expenses related to litigation matters, (xi) intangible assets write-off, (xii) integration related costs, (xiii) abnormal excess capacity, (xiv) foreign exchange gains and losses, (xv) non-GAAP income tax reconciling adjustments, and (xvi) other (gains) charges related to non-recurring activities.

We utilize a long-term projected non-GAAP tax rate to compute our non-GAAP income tax provision. The long-term projected non-GAAP tax rate is based on a multi-year projection of our estimated annual GAAP income tax forecast, adjusted to account for the tax effect of non-GAAP pretax adjustments as well as the effects of significant non-recurring and period specific tax items. Our non-GAAP tax provision for fiscal year 2024 is 14.5%. The difference between our GAAP income tax provision and our non-GAAP income tax provision is presented as non-GAAP income tax reconciling adjustments.

A quantitative reconciliation between GAAP and non-GAAP financial data with respect to historical periods is included in the supplemental financial table attached to this press release.
