• Net revenue of $533.8 million
• GAAP gross margin of 34.0%; Non-GAAP gross margin of 39.4%
• GAAP operating margin of 1.3%; Non-GAAP operating margin of 18.7%
• GAAP diluted net income per share of $0.05; Non-GAAP diluted net income per share of $1.10

Lumentum Holdings Inc. (“Lumentum” or the “Company”) today reported results for its fiscal first quarter ended September 27, 2025.

“In our fiscal first quarter, we saw year-over-year revenue growth of 58 percent and operating margin expansion of over 1,500 basis points on a non-GAAP basis. Revenue, operating margin, and earnings per share all came in at the high end of our guidance ranges,” said Michael Hurlston, Lumentum President and CEO.

“Our first-quarter results and forward guidance underscore our strong momentum across data center, data center interconnect, and long-haul markets. Our guidance indicates we expect more than 20 percent sequential revenue growth, even before meaningful contributions from two of our next major growth engines—optical circuit switches and co-packaged optics. Our third driver, cloud transceivers, is expected to grow in our second quarter and should now be on a sustainable upward path. With our broad optical portfolio, we are well positioned to support the rapid expansion of AI compute.”

Fiscal First Quarter Highlights:

Net revenue for the first quarter of fiscal year 2026 was $533.8 million, with GAAP net income of $4.2 million, or $0.05 per diluted share. Net revenue for the fourth quarter of fiscal year 2025 was $480.7 million, with GAAP net income of $213.3 million, or $2.96 per diluted share. Net revenue for the first quarter of fiscal year 2025 was $336.9 million, with GAAP net loss of $82.4 million, or $1.21 per diluted share.

Non-GAAP net income for the first quarter of fiscal year 2026 was $86.4 million, or $1.10 per diluted share. Non-GAAP net income for the fourth quarter of fiscal year 2025 was $63.3 million, or $0.88 per diluted share. Non-GAAP net income for the first quarter of fiscal year 2025 was $12.2 million, or $0.18 per diluted share.

The Company held $1,121.8 million in total cash, cash equivalents, and short-term investments at the end of the first quarter of fiscal year 2026, up $244.7 million from the end of the fourth quarter of fiscal year 2025.

The tables above provide comparisons of quarterly results to prior periods, including sequential quarterly and year-over-year changes. A reconciliation between GAAP and non-GAAP measures is contained in this release under the section titled “Use of Non-GAAP Financial Measures.”

Business Outlook

Lumentum expects the following for the second quarter of fiscal year 2026:

• Net revenue in the range of $630 million to $670 million
• Non-GAAP operating margin of 20.0% to 22.0%
• Non-GAAP diluted earnings per share of $1.30 to $1.50

We have not provided reconciliations from GAAP to non-GAAP financial measures or the equivalent GAAP measure for non-GAAP financial measures in our outlook, as they cannot be provided without unreasonable effort. A large portion of non-GAAP adjustments, such as stock-based compensation, acquisition related costs, integration related costs, restructuring and related charges, non-GAAP income tax reconciling adjustments, 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.

The following financial tables are presented in accordance with GAAP, unless otherwise specified.

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, 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, 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 importantly, to evaluate the methodology and information used by management to monitor, manage, evaluate and measure the Company’s business and results of operations. However, 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. Moreover, the non-GAAP financial measures we present may be different from non-GAAP financial measures used by other companies or may not be comparable to similarly titled measurements reported by other companies, limiting their usefulness for comparison purposes. We do not consider non-GAAP financial measures to be a substitute for, or superior to, the information provided by GAAP financial measures, and 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.

Our non-GAAP measures used in this press release exclude (i) stock-based compensation and related payroll taxes, (ii) acquisition related costs, (iii) integration related costs, (iv) amortization of acquired intangibles, (v) restructuring and related charges, (vi) foreign exchange (gains) losses, net, (vii) non-cash interest expense on convertible notes, (viii) intangible assets write-off, (ix) inducement expense on partial repurchase of 2026 Notes, (x) non-GAAP income tax reconciling adjustments, and (xi) other charges or income 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 2026 is 16.5%. 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.
